ABSTRACT

This study aimed to identify the related substances of phloroglucinol injection by two-dimensional liquid chromatography quadrupole time-of-flight mass spectrometry (2D-LC-Q-TOF/MS). The first-dimensional separation was carried out on an HSS T3 (250 mm × 4.6 mm, 5 μm) column by gradient elution using 1.36 g·L-1 potassium dihydrogen phosphate buffer solution (pH adjusted to 3.0 with diluted phosphoric acid) and acetonitrile as the mobile phases. The separated components were then trapped in switch valve tube lines respectively and delivered to the second-dimensional desalting gradient elution which was performed with a BDS C18 (100 mm × 4.6 mm, 2.4 μm) column using 0.1% formic acid and methanol as the mobile phases. After rapid desalting, electrospray-ionization quadrupole time-of-flight high resolution mass spectrometry was used for determining the accurate masses and elemental compositions of the parents and their product ions for both phloroglucinol and its related substance. Structures of the related substances were then figured out by mass spectrometry elucidation, organic reaction mechanism analysis, and/or comparison with reference substances. Under the established analytical conditions, phloroglucinol and its related substances were adequately separated, 17 main related substances were detected and identified in the injection and its stressed samples for the first time. The identification results can provide reference for the quality control of phloroglucinol injection.

ABSTRACT

In recent years, the research on the anti-tumor effect of traditional Chinese medicine has been increasing year by year. Both the effective extracted ingredients of Chinese medicine and its compound preparations have significant efficacy and advantages in tumor treatment. Costunolide, the active ingredient of Aucklandia lappa (a traditional Chinese medicine), is a natural sesquiterpene lactone, which has a variety of pharmacological effects, such as anti-oxidation, anti-inflammation, hypoglycemic effect, anti-microbial effect etc. In recent years, more and more experimental studies in vivo and in vitro have shown that this component has anti-tumor activity, which can inhibit the growth of breast cancer, gastric cancer, melanoma cancer, prostate cancer, leukemia, liver cancer, lung cancer, ovarian cancer, esophageal cancer, colorectal cancer, osteosarcoma and other tumors. Its antitumor mechanism mainly lies in the regulation of PI3K/AKT/mTOR, AKT-MDM 2-p53, ROS-AKT/GSK-3β, Bcr / Abl, Stat5 and other signaling pathways, which affects reactive oxygen species, apoptosis-related proteins, autophagy-related proteins, and cyclin, and thus induces apoptosis, causes autophagy and arrests cell cycle in G2 / M phase, G1 phase, and S phase. In addition, the combination of costunolide with imatinib and doxorubicin can attenuate toxicity and enhance anti-tumor effect, and also reverse tumor drug resistance. By consulting and sorting out the relevant research literature at home and abroad, the author summarized the research progress of costunolide on the antitumor effect and mechanism, the combined drug use and the reversal of tumor drug resistance in order to provide theoretical basis for the development and utilization of new drugs of this ingredient.

ABSTRACT

Objective: To investigate the expression differences of LLGL2 between prostatic ductal adenocarcinoma (PDA) and prostatic acinar adenocarcinoma, and its potential clinical significance. Methods: Eighteen patients diagnosed of PDA or prostatic acinar adenocarcinoma with PDA component by histopathology during January 2015 and December 2019 in the Beijing Hospital, China were retrospectively studied. The transcriptome analysis was conducted using the tissue of PDA and prostatic acinar adenocarcinoma. Differentially expressed genes and the differences in expression profiles were identified. Further, differentially expressed proteins were verified by immunohistochemistry. Results: The tissue from 8 of the 18 patients were used for transcriptome analysis, the results of which were compared with data from public databases. 129 differentially expressed genes were identified. 45 of them were upregulated while 84 were downregulated. The results of gene enrichment analysis and gene oncology (GO) analysis revealed that the differentially expressed genes were mostly enriched in the hypertrophic cardiomyopathy and interleukin-17 related pathways. GPAT2, LLGL2, MAMDC4, PCSK9 and SMIM6 were differentially expressed between PDA and prostatic acinar adenocarcinoma. Moreover, LLGL2 was more likely expressed in the cytoplasm (P=0.04) than the nucleus (P<0.01) in PDA, compared with prostatic acinar adenocarcinoma. Conclusions: The gene expression profiling indicates that PDA are very similar to prostatic acinar adenocarcinoma. Among the differentially expressed proteins screened and verified in this study, the expression of GPAT2, LLGL2, MAMDC4 and PCSK9 is increased in PDA, while that of SMIM6 is reduced in PDA. The expression of LLGL2 shows significantly different patterns between PDA and prostatic acinar carcinoma, and thus may help differentiate PDA from prostatic acinar adenocarcinoma in clinical practice.

ABSTRACT

Type 2 diabetes (T2D) is often accompanied with an induction of retinaldehyde dehydrogenase 1 (RALDH1 or ALDH1A1) expression and a consequent decrease in hepatic retinaldehyde (Rald) levels. However, the role of hepatic Rald deficiency in T2D progression remains unclear. In this study, we demonstrated that reversing T2D-mediated hepatic Rald deficiency by Rald or citral treatments, or liver-specific Raldh1 silencing substantially lowered fasting glycemia levels, inhibited hepatic glucogenesis, and downregulated phosphoenolpyruvate carboxykinase 1 (PCK1) and glucose-6-phosphatase (G6PC) expression in diabetic db/db mice. Fasting glycemia and Pck1/G6pc mRNA expression levels were strongly negatively correlated with hepatic Rald levels, indicating the involvement of hepatic Rald depletion in T2D deterioration. A similar result that liver-specific Raldh1 silencing improved glucose metabolism was also observed in high-fat diet-fed mice. In primary human hepatocytes and oleic acid-treated HepG2 cells, Rald or Rald + RALDH1 silencing resulted in decreased glucose production and downregulated PCK1/G6PC mRNA and protein expression. Mechanistically, Rald downregulated direct repeat 1-mediated PCK1 and G6PC expression by antagonizing retinoid X receptor α, as confirmed by luciferase reporter assays and molecular docking. These results highlight the link between hepatic Rald deficiency, glucose dyshomeostasis, and the progression of T2D, whilst also suggesting RALDH1 as a potential therapeutic target for T2D.

ABSTRACT

Objective:For tympanosclerosis patients with ossicular chain fixation, we use ossicular chain bypass technique and evaluate its long-term effects. Methods:From June 2017 to June 2019, 147 patients with tympanosclerosis who underwent middle ear surgery with otoscopy in Yinchuan First People's Hospital were reviewed. The subjects were divided into three groups according to the implemented operation plan, 51 cases in the ossicular chain mobilization group(OCM), 56 cases in the ossicular chain bypass reconstruction group(OCB), and 40 cases in the malleus-incus complex resection reconstruction group(MICR). Through a three-year follow-up, the medium and long-term effects of different operation plans were compared and analyzed. Results:There was no significant difference among the three groups in the incidence of tympanic membrane perforation, delayed facial nerve palsy, and the dispatch and displacement of PORP. The incidence of tympanic membrane retraction pocket or cholesteatoma after operation in OCB group(0) was significantly lower than that in OCM group(11.76%) and MICR group(7.5%)(P<0.05). At 12 months after operation, ΔABG of OCB group and MICR group were better than that in the OCM group(P<0.05). At 36 months after operation, ΔABG of OCB group was better than that in the OCM group(P<0.05), and there was no significant difference between OCB group and MICR group. The audiological performance of patients with epitympanic sclerosis(ETS) at 12, 24 and 36 months after operation was better than that of patients with posterior tympanosclerosis(PTS) and total tympanosclerosis(TTS)(P<0.05). Conclusion:Compared with patients undergoing ossicular chain mobilization and malleus-incus complex resection for ossicular chain reconstruction, patients with tympanosclerosis undergoing bypass technique have better and stable hearing prognosis in medium and long term. This technique can effectively prevent the formation of retracted pocket and cholesteatoma in patients with tympanosclerosis after operation.

ABSTRACT

Objective:To analyse the association between triglyceride glucose (TyG) index and the number of coronary artery lesions in patients with stable coronary artery disease.Methods:It was a cross-sectional study. Patients with stable coronary artery disease who were admitted to Zhongshan Hospital, Fudan University from 1st January 2019 to 30th April 2020 for percutaneous coronary intervention (PCI) were selected. We collected general clinical information and laboratory results from the enrolled patients, then calculated the TyG index. We evaluated coronary artery lesions by coronary angiography and analysed the factors associated with the number of coronary artery lesion branches by the logistic regression model.Results:A total of 832 patients were included in this study, 641 (77.0%) were male, the age was (64.6±11.5) years. The mean TyG index was 8.78. Patients with the TyG index≥8.78 were included in the high TyG index group (411 patients), and those with the TyG index<8.78 were included in the low TyG index group (421 patients). Compared with the low TyG index group, the high TyG index group had the higher body mass index and diastolic blood pressure, more smokers and diabetes mellitus, younger age of onset of coronary heart disease (all P<0.05), and a lower proportion of patients using statins ( P=0.027). Compared with the low TyG index group, the high TyG index group had the higher levels of erythrocyte count, hemoglobin, white blood cell count, albumin, urea nitrogen, uric acid, fasting blood glucose, HbA1c, triglyceride, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, apolipoprotein B, apolipoprotein E, and C-reactive protein (all P<0.05). However, the levels of high density lipoprotein, apolipoprotein A1 and apolipoprotein A were lower in the high TyG index group than those in the low TyG index group (all P<0.05). The number of coronary artery lesions in patients in the high TyG index group was 2.35±0.91, more than the low TyG index group 2.10±0.95 ( P<0.001).After adjusting for the other factors, multivariate logistic regression analysis showed that male, smoking history (smoking cessation or smoking), TyG index and troponin T levels were independently positively associated with the number of coronary artery lesions (all OR>1, P<0.05), while ApoA1 was independently negatively associated with the number of coronary artery lesions ( OR=0.140, P=0.007). Conclusions:TyG index is positively associated with the number of coronary artery lesions in patients with stable coronary artery disease.

ABSTRACT

Objective:To analyze the risk factors of three-vessel disease (TVD) in patients with stable coronary artery disease (SCAD).Methods:The clinical data of 447 patients with SCAD diagnosed in Zhongshan Hospital from May 2019 to April 2020 were retrospectively analyzed, including 108 cases with the single-vessel disease (SVD), 136 cases with the two-vessel disease, and 203 cases with three-vessel disease. The general data and hematological indexes were compared between patients with SVD and those with TVD; the related factors for TVD in SCAD patients were analyzed with univariate and multivariate logistic regression.Results:There were 244 males (78.5%) and 67 females (21.5%) with a median age of 57 years (64, 69). Univariate analysis showed that there were significant differences in diabetes history ( χ2=7.75, P=0.005), uric acid ( Z=-2.10, P=0.036), glycosylated hemoglobin ( Z=-2.77, P=0.006) and high density lipoprotein cholesterol (HDL-C) ( Z=-2.99, P=0.003) levels between SVD and TVD groups. Multivariate analysis showed that the high level of blood uric acid ( OR=1.01, 95% CI: 1.00-1.01, P<0.05) and the low level of HDL-C ( OR=3.29, 95% CI:1.23-8.85, P<0.05) were related risk factors of TVD. Conclusion:High blood uric acid level and low HDL-C level are related factors for TVD in patients with SCAD.

ABSTRACT

Objective:To evaluate the efficacy and safety of Rezūm Water Vapor Thermal Therapy system in the treatment of patients with benign prostatic hyperplasia (BPH).Methods:The clinical data of 22 patients with benign prostatic hyperplasia treated with Rezūm Water Vapor Thermal Therapy system in Boao Yiling Life Care Center in Hainan from December 2020 to January 2021 were retrospectively analyzed, with age of (61.0±5.9) years, prostate volume of (43.7±8.4) ml. international prostate symptom score (IPSS) of (19.3±3.7), quality of life (QOL) score of (4.2±0.8), maximum urinary flow rate (Q max) of (11.9±3.4) ml ml/s, and residual urine volume (PVR) of (14.0±19.0). For 19 patients with sexual life, the International Index of Erectile Function Questionnaire-5 (IIEF-5) were 17.0±5.5, the Men's Sexual Health Questionnaire-Ejaculatory Dysfunction Score (MSHQ-EjD) ejaculatory function score were 10.0±3.2, and the ejaculatory satisfaction score were 1.5±1.0. Twenty-two patients underwent Rezūm Water Vapor Thermal Therapy under intravenous anesthesia (general anesthesia without intubation) in the dorsal lithotomy position. The Rezūm system consisted of reusable thermal steam treatment device and disposable prostate thermal steam treatment instrument. The thermal steam treatment device used radiofrequency energy to heat sterile distilled water, generating high-temperature steam at 103℃. In a 9-second timeframe, the tissue temperature within each treatment area was raised approximately 70℃, causing cell death and resulting in a shrink in prostate tissue volume. The disposable prostate thermal steam treatment instrument could be inserted through a cystoscope and had a retractable needle tip that extends to a length of 10.25 mm. The needle tip had 12 evenly distributed holes arranged in three rows of four holes each, with a spacing of 120° between rows, allowing for even diffusion of thermal steam along the circumference. The patient was placed in a lithotomy position, and the disposable prostate thermal steam treatment instrument was used to examine the prostate, urethra, and bladder via cystoscopy, assessing the lateral lobes and median lobe of the prostate. The tissue spacing within each field of view of the treatment instrument is 0.5 cm, and the distance from the bladder neck to the verumontanum is calculated. The first needle was injected at 3 o’clock along the left lobe, withdrawing 2 fields of view each time. During the release of thermal steam, the needle tip was positioned perpendicular to the prostate urethral mucosa, and each needle injection delivered 0.42 ml of sterile distilled water-formed thermal steam into the prostate tissue. The thermal steam injection lasted for 9 seconds, followed by a 2-3 seconds waiting period before retracting the needle tip. One needle was injected per 2 fields of view, progressing towards the proximal urethra of the verumontanum. The same method was used to treat the right lobe. For cases with significant median lobe enlargement, two fields of view were retracted at the bladder neck, and the needle was inserted at a 45° angle. The second needle was injected at intervals determined by the extent of median lobe enlargement. Each puncture point was observed for no significant bleeding, and the instrument was then removed, with an F16/F18 silicone catheter left in place. The operative time as well as indwelling catheter time were recorded. The clinical parameters such as IPSS, QOL, prostate volume, Qmax, PVR, QOL, IIEF-5 and MSHQ-EjD at preoperative and 12 to 22 weeks post operation were compared. Adverse events from the Rezūm procedure to 12-22 weeks postoperatively were recorded. Results:All the operations were successfully completed. The operation time of Rezūm system was 3.9±1.6 min, and the indwelling catheter time after operation was 4.8±1.1 days. The IPSS scores of 22 patients at 12-22 weeks after operation were 4.4±3.3, whose reduction was 14.9±4.4 compared with these at baseline( P<0.01). The PV was (37.7±8.4)ml, Qmax was (25.5±9.6)ml/s, PVR was (6.2±8.1)ml, and QOL was 1.6±0.9, all demonstrating statistically significant differences compared to preoperative values ( P<0.05). Among the 19 cases with sexual activity, the IIEF-5 score was 20.4±3.2, and the ejaculatory function score of MSHQ-EjD was 13.1±3.1, both showing statistically significant differences compared to preoperative scores ( P<0.05). The ejaculatory satisfaction score of MSHQ-EjD was 1.1±0.5, and there was no statistically significant difference compared to preoperative scores ( P>0.05). None of the 22 cases required medication or further surgical treatment for BPH after surgery. There were no urethral injuries, rectal or bladder perforations during the surgeries, and no severe complications such as rectal fistula or bladder neck contracture occurred postoperatively. There were no deaths reported. Postoperative discomfort in the urethra occurred in 19 cases, urethral pain in 8 cases, hematuria in 15 cases, poor sleep quality in 2 cases, and constipation in 1 case, all of which resolved within 7 to 10 days after surgery. Erectile dysfunction and retrograde ejaculation occurred in one case each at 4 to 5 weeks postoperatively but did not reoccur thereafter. Prostatitis and nodular hyperplasia of the middle lobe of the prostate occurred in one case each at 21 weeks and 25 weeks postoperatively, respectively, and no treatment was administered. Conclusions:In the real world, the short-term overall effect of Rezūm Water Vapor Thermal Therapy system in the treatment of benign prostatic hyperplasia is satisfactory, which shows good efficacy and safety.

ABSTRACT

Objective:To compare the complications associated with various urinary flow diversion methods and identify the factors that contribute to the decline in renal function after radical total cystectomy for myoinfiltrating urothelial carcinoma.Methods:This study conducted a retrospective analysis on the clinical data of 46 patients with pathologically confirmed muscle-invasive bladder cancer.The patients underwent laparoscopic radical cystectomy with either ileal conduit diversion(n=21)or ureterocutaneous diversion(n=25)between January 2017 and December 2021.Perioperative data, postoperative pathology, postoperative complications, and follow-up results were compared between the two groups.Results:The study found significant differences between the two groups in terms of age[(67±6)years vs.(73±8)years, t=3.132, P=0.003], Charlson comorbidity index adjusted for age[(3.80±1.15) vs.(4.52±1.03), t=2.223, P=0.031], prognostic nutritional index[(48.81±5.74) vs.(43.64±4.74), t=3.347, P=0.002], operation time[(449±108)minutes vs.(326±130)minutes, P=0.001]], hospital stay[(20.1±11.1)days vs.(13.3±5.2)days, t=2.762, P=0.008], proportion of Clavien grade 3 or higher complications within 3 months after surgery(4/21 vs 0/25, χ2=2.105, P<0.05), and proportion of stoma-free patients(18/21 vs.5/25, χ2=6.373, P<0.01). According to Logistic multivariate analysis, perioperative blood transfusion and urinary tract infection were identified as independent risk factors for renal function decline 12 months after surgery.Escherichia coli was found to be the most common bacteria cultured from urinary tract infections in both groups after surgery. Conclusions:Laparoscopic radical cystectomy with ureterocutaneous diversion offers benefits such as shorter hospital stays and fewer perioperative complications for older and frail patients.However, a higher proportion of patients may require ureteral stenting.It is important to note that perioperative blood transfusion and urinary tract infection are major risk factors for renal function decline following radical cystectomy.

ABSTRACT

Objective:To investigate the practicality and safety of performing a radical prostatectomy(RP)shortly after the diagnosis of prostate cancer using a combination of prostate targeted biopsy and intraoperative frozen section.Methods:Prospective enrollment was conducted for patients suspected of having prostate cancer based on abnormal prostate specific antigen(PSA)levels.The inclusion criteria for the study were as follows: patients aged 80 years or younger with an ECOG score of 1 or lower.Prior to biopsy, patients underwent both prostate magnetic resonance imaging(MRI)and prostate specific membrane antigen positron emission tomography/computed tomography(PSMA PET/CT)to determine the likelihood of prostate cancer with clinical stages within T 2-3aN 0M 0.In order to be included in the study, patients must agree to receive RP after their prostate cancer diagnosis has been confirmed by biopsy.All enrolled patients underwent a targeted prostate biopsy, consisting of 1-2 cores.These specimens were then examined through frozen section analysis.For patients diagnosed with prostate cancer through intraoperative frozen section pathology, RP was immediately performed.In this study, transperineal prostate targeted+ systematic biopsy was utilized for patients with undiagnosed prostate cancer.Additionally, routine pathological examination of specimens was conducted.The study analyzed the baseline data, surgical conditions, pathological results, and follow-up information of patients in a descriptive manner. Results:Seven patients, ranging in age from 54 to 77 years with a mean age of 66.7 years, were enrolled in the study.Their mean PSA level was 12.668 μg/L, ranging from 4.359 to 22.195 μg/L.Of these patients, 4 had a PI-RADS score of 4 and 3 had a score of 5.The maximum diameter of the index lesion was 1.3 cm, ranging from 0.5 to 2.2 cm.PSMA PET/CT scores were 4 in 1 case and 5 in 6 cases.The index lesions detected by PSMA PET/CT were consistent with those detected by MRI, and the maximum standardized uptake value(SUVmax)was 15.7, ranging from 5.3 to 39.4.Prostate cancer was diagnosed through targeted biopsy and intraoperative frozen section pathology.Four cases had a Gleason score of 3+ 3=6, while one case had a Gleason score of 3+ 4=7, another had a score of 4+ 3=7, and the last had a score of 4+ 4=8.All patients underwent RP treatment immediately after the prostate cancer diagnosis.Only one patient had slight adhesion at the apex of the prostate, while the other six patients were evaluated by surgeons as having no obvious adhesion at the apex.All surgeries were completed successfully, with a mean operation time of 149.7(ranging from 108 to 255)minutes.After RP, whole mount pathology results indicated that all cases were prostate adenocarcinoma, with a Gleason score of 3+ 4=7 in four cases and 4+ 3=7 in three cases.The pathological stages were pT2 in three cases and pT3a in four cases, with five cases having negative surgical margins and two cases with positive surgical margins.During the study, all patients were monitored for a period of 5.4 months(ranging from 3 to 7 months)and no complications of Clavien Dino≥Ⅰ were observed.PSA levels were measured at 6 weeks and 3 months after surgery, with readings of 0.020 μg/L(ranging from 0 to 0.079 μg/L)and 0.016 μg/L(ranging from 0 to 0.087 μg/L), respectively.No hormonal therapy or radiotherapy was administered during this time.Four patients were able to recover from urinary continence.Conclusions:Based on a combination of MRI and PSMA PET/CT, it is both safe and feasible to promptly perform RP following the diagnosis of prostate cancer through targeted biopsy for index lesions, along with intraoperative frozen section.

ABSTRACT

Objective:To explore the difference of clinical characteristics between senile Parkinson's disease(PD)with depression and unipolar depression.Methods:From March 2019 to March 2020, 53 patients with Parkinson's disease depression and 57 patients with unipolar depression who were admitted to the neurology department of Beijing Hospital were continuously collected.The gender, age and education level of the patients were recorded.The course of disease and other general data of the patients with Parkinson's disease were also recorded.Depression and anxiety of the patients were evaluated by Beck Depression Inventory(BDI)and Generalized Anxiety Disorder Scale(GAD-7). Quality of life of patients with Parkinson's disease was evaluated by 8-item Parkinson's disease questionnaire(PDQ-8). Differences in the assessment results and quality of life scores between the two groups were analyzed.Results:The incidence of depression comorbid with anxiety in elderly PD patients was 52.8%(28/53), lower than that in elderly unipolar depression patients comorbid with anxiety [84.2%(48/57)]( χ2=12.664, P<0.001). The scores of activity inhibition [(1.8±0.8)points]and hyposexuality [(0.4±1.0)points]in elderly PD patients with comorbid depression were higher than that in patients with unipolar depression [(1.1±0.8)points, (0.0±0.0)points]( t=4.399, 2.942, P<0.001, =0.005). Moreover, the incidence of activity inhibition(98.1%)and hyposexuality(15.1%)in PD patients with comorbid depression was higher than that in patients with unipolar depression(78.9%, 0.0%)( χ2=9.680, 9.279, both P=0.002). The scores of self-blame [(1.0±0.8)points]and pain [(1.0±0.8)points]in elderly patients with unipolar depression were higher than those in PD patients with comorbid depression [(0.5±0.7)points, (0.9±0.7)points]( t=-3.902, -2.486, P<0.001, =0.014). Moreover, the incidence of self-blame(66.7%), irritability(78.9%)and image distortion(56.1%)in elderly patients with unipolar depression was higher than that in PD patients(35.8%, 56.6%, 35.8%)( χ2=10.447, 6.320, 4.547, P=0.001, 0.012, 0.033). The scores of PDQ-8 in PD patients with comorbid depression and anxiety [14.8(10.8, 19.0)points]( Z=-3.544, P<0.001)were higher than those in PD patients with depression only [7.0(4.8, 11.0)points]. Conclusions:The focus of depression in elderly PD patients is different from that in elderly unipolar depression patients.Elderly patients with unipolar depression are more likely to be comorbid with anxiety.Depression reduces the quality of life in PD patients, and the comorbidity of anxiety further reduces the overall quality of life in PD patients with depression.

ABSTRACT

Objective:To assess the efficacy of Tamsulosin monotherapy for overactive bladder(OAB)symptoms in benign prostatic hyperplasia(BPH)patients with the prostate volume(PV)<40 ml, and to analyze related factors affecting the efficacy.Methods:300 BPH patients with OAB were enrolled, with an average age of(66.9±7.7)years and the PV<40 ml.Smoking, drinking and other living habits were investigated.Data on the Overactive Bladder Symptom Score(OABSS), International Prostate Symptom Score(IPSS)and Quality of Life Scale(QOLS)were collected before and after 4 weeks of treatment with Tamsulosin 0.2 mg QN.The maximum urine flow rate(Qmax)and bladder residual urine volume(PVR)were measured before and after treatment.OBASS was used as the main assessment parameter to analyze the correlation of efficacy with age, lifestyle, pre-treatment symptom scores, PV, Qmax and PVR.Results:257 patients completed the study, and 169 patients were treated effectively, with an overall effectiveness rate of 65.8%.The effectiveness rates of the mild, moderate and severe OAB groups were 83.6%, 62.4% and 38.5%, respectively, with statistical significance( χ2=13.037, P=0.001).3 patients showed adverse drug reactions, including 2 patients with mild dizziness and 1 patient with nausea.The baseline OABSS score, the proportion of smoking patients and the proportion of drinking patients in the effectively treated OAB group were significantly lower than those in the ineffectively treated group.Multivariate analysis showed that baseline OABSS score( OR=0.735, P<0.001)and smoking( OR=2.111, P=0.029)were correlated with tamsulosin's efficacy in treating BPH patients with OAB with PV<40 ml. Conclusions:The effectiveness rate of Tamsulosin for the treatment of BPH patients with mild OAB with PV<40 ml is high.The baseline OABSS score and smoking are factors affecting the efficacy of Tamsulosin on OAB symptoms in these patients.

ABSTRACT

Objective:To investigate the safety and efficacy of MR-guided focused ultrasound surgery (MRgFUS) in treating localized prostate cancer.Methods:Six patients with localized prostate cancer who underwent MRgFUS treatment from August 2020 to September 2021 in Beijing Hospital were prospectively enrolled in this study. The patients were all over 18 years old, with an average age of (68±10) years, and had not received any prior treatment for prostate cancer. Pretreatment pelvic MR and CT scans were performed to determine the region of treatment (ROT). Different urinary catheterization measures were given based on the location of the lesion. Under general anesthesia, the lesions were treated by MRgFUS using a specialized rectal ultrasound transducer on the treatment bed. The patients were followed up at 1, 3, and 6 months after treatment and annually thereafter. During follow-up, prostate-specific antigen (PSA) levels, pelvic MR scans, International Prostate Symptom Score (IPSS), International Index of Erectile Function-15 (IIEF-15) scores, and adverse events were assessed.Results:(1) All six patients underwent MRgFUS treatment for six lesions, with an average duration of (126±56) minutes, an average number of (7.3±3.2) focal ultrasound pulses per lesion, and an average non-perfusion volume of (3.8±1.1) cm 3, which covered the entire treatment target area. No treatment-related adverse events were reported. (2) The PSA levels at baseline, 1, 3, 6, and 12 months after treatment were (6.6±0.8), (3.6±1.3), (3.4±3.0), (2.5±1.7), and (2.3±1.8) ng/ml, respectively. PSA levels increased in 2 out of 6 patients during follow-up, and pelvic MR scan revealed recurrent lesions, while PSA levels continued to decrease in the remaining 4 patients, and pelvic MR scan were normal. (3) The IPSS scores at baseline, 1, and 3 months after treatment were 13.0 (4.0, 16.0), 10.0 (4.0, 12.0), and 5.0 (3.0, 6.0) points, respectively. For the three sexually active patients, the IIEF-15 scores at baseline were 40, 51, and 14 points, respectively, and IIEF-15 at 1 month after treatment were 9, 8, and 14 points, respectively, and at 3 months after treatment were 9, 66 and 26 points, respectively. (4) One patient was diagnosed with recurrence 10 months after treatment, and another patient was found to have a new lesion 6 months after treatment. Conclusions:MRgFUS might be a safe, non-invasive, and effective treatment for localized prostate cancer, but regular follow-up is vital for detecting tumor recurrence.

ABSTRACT

Objective:To explore the value of fetal lung volume and mediastinal shift angle (MSA) based on fetal MRI in predicting the prognosis of congenital diaphragmatic hernia (CDH).Methods:Fetuses with left CDH that did fetal MRI in Xinhua Hospital Affiliated with Shanghai Jiao Tong University School of Medicine from September 2016 to January 2022 were retrospectively collected. There were 65 patients, and their gestational age was 29 (26, 35) weeks when they were diagnosed with left CDH by MRI. Observed fetal lung volume and MSA were measured based on fetal MRI, and observed/expected lung volume (o/eFLV) based on gestational age was calculated. The clinical data were collected from birth to discharge, and patients were divided into survival group and death group in case of prognosis at discharge, with 54 cases in the survival group and 11 cases in the death group. The student′s t test was used to compare the difference of o/eFLV and MSA between the survival group and the death group, and the receiver operating characteristic (ROC) curve was used to evaluate the value of o/eFLV and MSA in predicting the prognosis of left CDH. Results:The o/eFLV of the survival group was 51.5%±18.3%, higher than that of the death group (27.8%±4.4%), and the difference was significant ( t=8.29, P<0.001). The MSA of the survival group was 33.1°±1.2°, lower than that of the death group (41.8°±2.7°), and the difference was significant ( t=-11.15, P<0.001). The area under the ROC curve (AUC) of o/eFLV to predict the fetal survival or death was 0.939 (95%CI 0.851-0.983), the cutoff value was 33.8%, the sensitivity was 100%, the specificity was 88.9%. The AUC of MSA was 0.998 (95%CI 0.941-1.000), the cutoff value was 37.2°, the sensitivity was 100%, the specificity was 98.2%. Conclusions:The o/eFLV and MSA that were measured based on fetal MRI can effectively predict the fetus′s prognosis with left CDH.

ABSTRACT

Objective:To investigate the clinical features, diagnostic methods and treatments of left ventricular apical fibroma.Methods:The clinical manifestations, ECG, imaging features and treatment plans of 2 patients with giant fibroma of left ventricular apex diagnosed in September 2020 and May 2022 were analyzed retrospectively, and the related literature was reviewed.Results:Both patients had slight chest distress and discomfort after activities. The ECG showed T-wave inversion of different degrees, which were misdiagnosed as “myocarditis” and “coronary heart disease” respectively. The cardiac magnetic resonance imaging and echocardiography showed left ventricular apical mass. Coronary artery stenosis was not found in coronary angiography. One patient required conservative treatment, and there was no significant change in clinical symptoms and tumor size in the follow-up for half a year; Another patient underwent cardiac mass removal, and the pathological examination after operation confirmed that it was cardiac fibroma, and there was no recurrence in the follow-up 2 years.Conclusion:Fibroma of left ventricular apex is a rare cardiac tumor, which is easy to be missed and misdiagnosed, and is one of the rare causes of T-wave inversion. Cardiac magnetic resonance imaging, CT and echocardiography are commonly used imaging methods to diagnose cardiac fibroma, and surgical resection is an effective treatment.

ABSTRACT

Objective:To investigate the clinical efficacy of radical resection of rectal cancer with different surgical approaches and influencing factors of postoperative complications.Methods:The retrospective study was conducted. The clinicopathological data of 3 418 patients who underwent radical resection of rectal cancer in the Second Affiliated Hospital of Harbin Medical University from July 2011 to September 2020 were collected. There were 2 060 males and 1 358 females, aged (61±11)years. Patients meeting the requirements of radical resection and surgical indications underwent surgeries choosing from open radical colorectal cancer surgery, laparoscopic radical colorectal cancer surgery, and natural orifice specimen extraction surgery (NOSES). Observation indicators: (1) intraoperative and postoperative conditions of patients undergoing different surgical approaches; (2) comparison of preoperative clinical characteristics in patients undergoing different surgical approaches; (3) comparison of postoperative histopathological characteristics in patients undergoing different surgical approaches; (4) postoperative complications of patients undergoing different surgical approaches; (5) analysis of influencing factors of postoperative complications. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range), and comparisons between groups was analyzed using the Kruskal-Wallis rank test. Comparison of ordinal data was analyzed using the non-parameter rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Multivariate analysis was conducted using the Logistic regression model. Results:(1) Intraoperative and postoperative conditions of patients undergoing different surgical approaches. Of the 3 418 patients, 1 978 cases underwent open radical colorectal cancer sur-gery, 1 028 cases underwent laparoscopic radical colorectal cancer surgery and 412 cases underwent NOSES, respectively. The operation time, volume of intraoperative blood loss, cases with permanent stoma, preventive stoma or without fistula, time to postoperative first flatus, time to postoperative liquid food intake, cases transferred to intensive care unit after surgery, duration of postoperative hospital stay were 145(range, 55?460)minutes, 100(range, 30?1 000)mL, 435, 88, 1 455, 72(range, 10?220)hours, 96(range, 16?296)hours, 158, 10(range, 6?60)days, respectively, in patients undergoing open radical colorectal cancer surgery. The above indicators were 175(range, 80?450)minutes, 50(range, 10?800)mL, 172, 112, 744, 48(range, 14?120)hours, 72(range, 38?140)hours, 17, 9(range, 4?40)days, respectively, in patients undergoing laparoscopic radical colorectal cancer surgery and 180(range, 80?400)minutes, 30(range, 5?500)mL, 0, 45, 367, 48 (range, 14?144)hours, 72(range, 15?148)hours, 1, 6(range, 3?30)days, respectively, in patients undergoing NOSES. There were significant differences in the above indicators among the patients undergoing different surgical approaches ( H=291.38, 518.56, χ2=153.82, H=408.86, 282.97, χ2=78.66, H=332.30, P<0.05). (2) Com-parison of preoperative clinical characteristics in patients undergoing different surgical approaches. The gender, age, body mass index, cases with diabetes, cases with hypertension, cases with coronary heart disease, cases with anemia, cases with hypoproteinemia, cases with intestinal obstruction, tumor location, preoperative carcinoembryonic antigen, preoperative CA19-9 showed significant differences among patients undergoing open radical colorectal cancer surgery, laparoscopic radical colorectal cancer surgery and NOSES ( P<0.05). (3) Comparison of postoperative histopathological characteris-tics in patients undergoing different surgical approaches. Tumor histological type, tumor differentiation degree, tumor diameter, number of lymph node detected, nerve invasion, vascular invasion, lymph node invasion, tumor T staging, tumor N staging, tumor M staging, tumor TNM staging showed significant differences among patients undergoing open radical colorectal cancer surgery, laparos-copic radical colorectal cancer surgery and NOSES ( P<0.05). (4) Postoperative complications of patients undergoing different surgical approaches. Cases with postoperative complications as anastomotic leakage, abdominal infection, intestinal obstruction, anastomotic bleeding, incision complications, pulmonary infection, other complications were 52, 21, 309, 8, 130, 51, 59, respectively, in patients undergoing open radical colorectal cancer surgery. The above indicators were 33, 17, 75, 3, 45, 58, 9, respectively, in patients undergoing laparoscopic radical colorectal cancer surgery and 13, 4, 8, 0, 11, 10, 15, respectively, in patients undergoing NOSES. There were significant differences in the intes-tinal obstruction, incision complications, pulmonary infection, other complications among patients undergoing different surgical approaches ( χ2=122.56, 13.33, 20.44, 15.59, P<0.05) and there was no significant difference in the anastomotic leakage, abdominal infection, anastomotic bleeding among patients undergoing different surgical approaches ( χ2=0.96, 2.21, 3.08, P>0.05). (5) Analysis of influencing factors of postoperative complications. ① Analysis of influencing factors of intestinal obstruction in patients with radical resection of rectal cancer. Age as 20?39 years and 40?59 years, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of intestinal obstruction in patients with radical resection of rectal cancer ( odds ratio=0.46, 0.59, 0.43, 0.13, 95% confidence interval as 0.21?1.00, 0.36?0.96, 0.33?0.56, 0.06?0.27, P<0.05). ② Analysis of influencing factors of incision complications in patients with radical resection of rectal cancer. Body mass index as 24.0?26.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of incision complications in patients with radical resection of rectal cancer ( odds ratio=0.24, 0.63, 0.46, 95% confidence interval as 0.11?0.51, 0.44?0.89, 0.24?0.87, P<0.05). ③ Analysis of influencing factors of pulmonary infection in patients with radical resection of rectal cancer. The surgical approach as laparoscopic radical colorectal cancer surgery was an independent risk factor of pulmonary infection in patients with radical resection of rectal cancer ( odds ratio=2.15, 95% confidence interval as 1.46?3.18, P<0.05), and tumor TNM staging as 0?Ⅰ stage was an independent protective factor ( odds ratio=0.10, 95% confidence interval as 0.01?0.88, P<0.05). ④ Analysis of influencing factors of other complica-tions in patients with radical resection of rectal cancer. Age as 20?39 years, 40?59 years, 60?79 years, body mass index as <18.5 kg/m 2, 18.5?23.9 kg/m 2, 24.0?26.9 kg/m 2, 27.0?29.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery were independent protective factors of other complications in patients with radical resection of rectal cancer ( odds ratio=0.10, 0.29, 0.37, 0.08, 0.22, 0.35, 0.32, 0.29, 95% confidence interval as 0.01?0.81, 0.13?0.64, 0.17?0.78, 0.02?0.40, 0.09?0.52, 0.15?0.83, 0.12?0.89, 0.14?0.59, P<0.05). Conclusions:Compared to laparoscopic radical colorectal cancer surgery and NOSES, open radical colorectal cancer surgery has wide indication and short operation time, but less perioperative treatment effect. Laparoscopic radical colorectal cancer surgery and NOSES can achieve better surgical result and less postoperative complication when patients meeting surgical indications.

ABSTRACT

ObjectiveTo explore the association between daily executive function and core symptoms, the symptoms of attention deficit hyperactivity disorder (ADHD) in children with autism spectrum disorder (ASD), and the moderating effect of theory of mind and other cognitive abilities on this association. MethodsChildren aged 6-12 years with ASD were recruited, and 86 children were identified according to the inclusion and exclusion criteria. Wechsler Intelligence Test for Children, Fourth Edition (WISC-Ⅳ), Strange Story Test (SST) and Behavior Rating Inventory of Executive Function (BRIEF) were used to evaluate children's cognitive ability. Swanson Nolan and Pelham-Version Ⅳ Scale (SNAP-Ⅳ), Social Responsiveness Scale (SRS), and Repetitive Behavior Scale-Revise (RBS-R) were used to assess the severity of ADHD symptoms, social impairment, and repetitive stereotyped behavior. Multiple linear regression was used to explore the association between daily executive function and ADHD symptoms, social impairment, repetitive stereotyped behaviors. ResultsAfter controlling for the score of strange stories, verbal comprehension index (VCI) and other factors, the full scale score and each index of BRIEF were positively correlated with full scale score of SNAP (b = 0.619-0.741, b’ = 0.637-0.755), SRS (b = 0.928-1.200, b’ = 0.417-0.513) and RBS-R (b = 0.326-0.525, b’ = 0.339-0.520) in children with ASD (P< 0.05), and the SNAP total score was more strongly correlated with the full scale BRIEF score and each index score (b’ = 0.637-0.755,P< 0.01). In addition to daily executive function, strange stories score (b = -2.218- -1.839) and age (b = 3.181-4.037) were also the important factors affecting the social function of children with ASD (P< 0.01). There were no moderating effects of strange stories score and age on the association between BRIEF score and full scale score of SNAP, SRS, and RBS-R(P> 0.05). ConclusionThe deficits of daily executive function in school-aged ASD children are significantly associated with core symptoms and ADHD symptoms, and the association is independent of other cognitive domains, such as theory of mind and verbal comprehension intelligence quotient.

ABSTRACT

ObjectiveTo explore the prenatal diagnostic methods of 18q deletion syndrome and improve understanding on the value of non-invasive prenatal testing (NIPT) in prenatal diagnosis of 18q deletion syndrome. Methods18q deletion syndrome was detected by conventional methods such as serological screening, ultrasonic imaging examination, chromosome karyotype analyses of both amniotic fluid cells and parental peripheral blood, and molecular biological techniques including NIPT, chromosomal microarray analysis (CMA) and copy number variation sequencing (CNV-Seq). Genetic counseling was conducted based on these examination results. ResultsNIPT identified a 24 MB deletion on the chromosome 18 which contained 17 genes including BCL2 by karyotype analysis of amniotic fluid cells and CMA. Further ultrasonic imaging examination confirmed the diagnosis of 18q deletion syndrome and karyotype analysis of parental peripheral blood revealed a de novo deletion mutation. ConclusionsInterventional prenatal diagnosis is an integral standard for the diagnosis of 18q deletion syndrome. NIPT, as an important screening test in middle pregnancy, can indicate the early possible chromosome segment deletion and reduce the time and economic cost when no abnormality is found in ultrasonic imaging.

ABSTRACT

This work aimed to investigate the differences of pharmacokinetics and tissue distribution of four alkaloids in Ermiao Pills and Sanmiao Pills in normal and arthritic model rats. The rat model of arthritis was established by injecting Freund's complete adjuvant, and ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) in the positive ion multiple reaction monitoring(MRM) mode was used for the determination of four alkaloids in plasma and tissues of normal and arthritic rats after administration of Ermiao Pills and Sanmiao Pills, respectively. The differences in pharmacokinetics and tissue distribution of the four active components were compared, and the effect of Achyranthis Bidentatae Radix on the major components of Sanmiao Pills was explored. This study established an UPLC-MS/MS for simultaneous determination of four alkaloids, and the specificity, linearity, accuracy, precision, and stability of this method all met the requirements. Pharmacokinetics study found that as compared with normal rats, the AUC and C_(max) of phellodendrine, magnoflorine, berberine and palmatine in model rats were significantly decreased after administration of Ermiao Pills, the clearance rate CL/F was significantly increased, and the distribution and tissue/plasma concentration ratio of the four alkaloids in the liver, kidney, and joint were significantly reduced. Achyranthis Bidentatae Radix increased the AUC of phellodendrine, berberine, and palmatine, reduced the clearance rate, and significantly increased the distribution of the four alkaloids in the liver, kidney, and joints in arthritic rats. However, it had no significant effect on the pharmacokinetics and tissue distribution of the four alkaloids in normal rats. These results suggest that Achyranthis Bidentatae Radix may play a guiding role in meridian through increasing the tissue distribution of effective components in Sanmiao Pills under arthritis states.
