ABSTRACT

Objective: To investigate the outcome of patients with esophagogastric junction cancer undergoing thoracoscopic laparoscopy-assisted Ivor-Lewis resection. Methods: Eighty-four patients who were diagnosed with esophagogastric junction cancer and underwent Ivor-Lewis resection assisted by thoracoscopic laparoscopy at the National Cancer Center from October 2019 to April 2022 were collected. The neoadjuvant treatment mode, surgical safety and clinicopathological characteristics were analyzed. Results: Siewert type Ⅱ (92.8%) and adenocarcinoma (95.2%) were predominant in the cases. A total of 2 774 lymph nodes were dissected in 84 patients. The average number was 33 per case, and the median was 31. Lymph node metastasis was found in 45 patients, and the lymph node metastasis rate was 53.6% (45/84). The total number of lymph node metastasis was 294, and the degree of lymph node metastasis was 10.6%(294/2 774). Among them, abdominal lymph nodes (100%, 45/45) were more likely to metastasize than thoracic lymph nodes (13.3%, 6/45). Sixty-eight patients received neoadjuvant therapy before surgery, and nine patients achieved pathological complete remission (pCR) (13.2%, 9/68). Eighty-three patients had negative surgical margins and underwent R0 resection (98.8%, 83/84). One patient, the intraoperative frozen pathology suggested resection margin was negative, while vascular tumor thrombus was seen on the postoperative pathological margin, R1 resection was performed (1.2%, 1/84). The average operation time of the 84 patients was 234.5 (199.3, 275.0) minutes, and the intraoperative blood loss was 90 (80, 100) ml. One case of intraoperative blood transfusion, one case of postoperative transfer to ICU ward, two cases of postoperative anastomotic leakage, one case of pleural effusion requiring catheter drainage, one case of small intestinal hernia with 12mm poke hole, no postoperative intestinal obstruction, chyle leakage and other complications were observed. The number of deaths within 30 days after surgery was 0. Number of lymph nodes dissection, operation duration, and intraoperative blood loss were not related to whether neoadjuvant therapy was performed (P>0.05). Preoperative neoadjuvant chemotherapy combined with radiotherapy or immunotherapy was not related to whether postoperative pathology achieved pCR (P>0.05). Conclusion: Laparoscopic-assisted Ivor-Lewis surgery for esophagogastric junction cancer has a low incidence of intraoperative and postoperative complications, high safety, wide range of lymph node dissection, and sufficient margin length, which is worthy of clinical promotion.

ABSTRACT

@#Objective     To explore the causes of conversion to thoracotomy in patients with minimally invasive esophagectomy (MIE) in a surgical team, and to obtain a deeper understanding of the timing of conversion in MIE. Methods     The clinical data of patients who underwent MIE between September 9, 2011 and February 12, 2022 by a single surgical team in the Department of Thoracic Surgery of the Fourth Hospital of Hebei Medical University were retrospectively analyzed. The main influencing factors and perioperative mortality of patients who converted to thoracotomy in this group were analyzed. Results     In the cohort of 791 consecutive patients with MIE, there were 520 males and 271 females, including 29 patients of multiple esophageal cancer, 156 patients of upper thoracic cancer, 524 patients of middle thoracic cancer, and 82 patients of lower thoracic cancer. And 46 patients were converted to thoracotomy for different causes. The main causes for thoracotomy were advanced stage tumor (26 patients), anesthesia-related factors (5 patients), extensive thoracic adhesions (6 patients), and accidental injury of important structures (8 patients). There was a statistical difference in the distribution of tumor locations between patients who converted to thoracotomy and the MIE patients (P<0.05). The proportion of multiple and upper thoracic cancer in patients who converted to thoracotomy was higher than that in the MIE patients, while the proportion of lower thoracic cancer was lower than that in the MIE patients. The perioperative mortality of the thoracotomy patients was not significantly different from that of the MIE patients (P=1.000). Conclusion     In MIE, advanced-stage tumor, anesthesia-related factors,extensive thoracic adhesions, and accidental injury of important structures are the main causes of conversion to thoracotomy. The rate varies at different tumor locations. Intraoperative conversion to thoracotomy does not affect the perioperative mortality of MIE.

ABSTRACT

Objective:To investigate the effect of immune checkpoint inhibitors combined with concurrent chemotherapy for non-small cell lung cancer (NSCLC) and the effect of this regimen on serum levels of tumor marker and immune cells of patients.Methods:The clinical data of 60 NSCLC patients in Xuzhou Cancer Hospital from February 2020 to February 2022 were retrospectively analyzed, and they were divided into chemotherapy combined with immune checkpoint inhibitor treatment group (combination treatment group) and conventional chemotherapy group by treatment methods, with 30 cases in each group. Before treatment and 6 weeks after treatment, the patients' serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), vascular endothelial growth factor (VEGF), cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) were detected by chemiluminescence immunoassay, and the levels of serum tumorous M2 pyruvate kinase (TuM2-PK) and fatty acid synthase (FAS) were detected by double-antibody sandwich enzyme-linked immunosorbent assay. The levels of T cell subsets were measured by flow cytometry, and the quality of life of patients was evaluated according to the World Health Organization quality of life scale brief version (WHOQOL-BREF). The clinical efficacy, tumor markers levels, immune cells levels, quality of life and adverse reactions were compared between the two groups.Results:The overall effective rate of patients in the combination treatment group was 46.67% (14/30), which was higher than 20.00% (6/30) in the conventional chemotherapy group ( χ2 = 4.80, P = 0.029). The differences in serum CEA, CA125, VEGF, CYFRA21-1, TuM2-PK, FAS levels and the proportions of CD3 +, CD4 +, CD8 + T cells and WHOQOL-BREF scores between the two groups before treatment were not statistically significant (all P > 0.05); the levels of CEA, CA125, VEGF, CYFRA21-1, TuM2-PK, FAS and the proportion of CD8 + T cells at 6 weeks after treatment were lower than those before treatment in both groups (all P < 0.05), and the proportions of CD3 + and CD4 + T cells and WHOQOL-BREF scores were higher than those before treatment (all P < 0.05); the levels CEA, CA125, VEGF, CYFRA21-1, TuM2-PK and the proportions of CD8 + T cells in the combination treatment group at 6 weeks after treatment were higher than those in the conventional chemotherapy group at 6 weeks after treatment (all P < 0.001), and the proportions of CD3 + and CD4 + T cells and WHOQOL-BREF scores were higher than those in the conventional chemotherapy group at 6 weeks after treatment (all P < 0.05). The differences in the incidence of gastrointestinal reactions, alopecia, leukopenia, thrombocytopenia, and liver and kidney function impairment between the two groups were not statistically significant (all P > 0.05). Conclusions:Immune checkpoint inhibitors combined with chemotherapy in NSCLC patients are more effective than conventional chemotherapy, and the combined treatment can more effectively reduce the serum tumor marker levels of patients and enhance the anti-tumor immune effect, with the adverse reactions comparable to conventional chemotherapy.

ABSTRACT

Objective: To investigate the neural connections between Shenmen (HT7)-heart and the brain by observing the tracing viruses co-labeled brain nuclear groups after injection of the pseudorabies viruses (PRV), the reverse transsynaptic virus tracer carrying different fluorescent protein genes, into the myocardium and Shenmen (HT7) point, respectively.Methods: Pseudorabies virus 531 (PRV531) carrying the green fluorescent protein gene and pseudorabies virus 724 (PRV724) carrying the red fluorescent protein gene were injected into the left ventricular wall and Shenmen (HT7) point area of the left forelimb of six C57BL/6 mice, respectively. After 120 h, whole brain tissue was extracted under 4% paraformaldehyde perfusion to prepare brain sections. Neuronal co-labeling with the tracing viruses was observed under fluorescence microscopy. Results: Co-labeled signals from the mouse ventricular wall and Shenmen (HT7) point region were found at all levels of the mouse central nervous areas, such as the cerebral cortex, hypothalamus, midbrain, pons, and medulla oblongata. The number of co-labeled neurons was higher in the primary motor area, the hypothalamic paraventricular nucleus, the subceruleus nucleus, and the paramedian reticular nucleus. Conclusion: There is a neural connection between Shenmen (HT7), the heart, and the brain, which may be most closely related to the autonomic nervous system.

ABSTRACT

Objective:To explore the clinical value of aspirin combined with atorvastatin in the prevention of new onset atrial fibrillation after off-pump coronary artery bypass grafting (OPCABG).Methods:208 patients with coronary artery bypass grafting in our hospital from June 2019 to June 2021 were selected as the research subjects and divided by a random number table method into groups. The control group (104 cases) was treated with aspirin before operation, and the observation group (104 cases) was treated with aspirin and atorvastatin before operation. ECG monitoring was carried out continuously for 7 days of patients in the two groups, and the occurrence and duration of AF were recorded. The clinical therapeutic efficacy, incidence and adverse reactions of AF, left atrial diameter and high-sensitivity C-reactive protein (hs-CRP) level were observed before and after treatment.Results:The incidence of AF in the observation group was significantly lower than that in the control group, the difference was statistically significant ( P<0.05). There was no statistical significant difference in the starting time of AF between the two groups after operation ( P>0.05). The duration of AF in the observation group was better than that in the control group, the difference was statistically significant ( P<0.05). Before treatment, there was no statistical significant difference in left atrial diameter and hs-CRP level between the two groups ( P>0.05). After treatment, the left atrial diameter in the observation group returned to that before treatment, and there was no statistical significant difference in the same group ( P>0.05). The left atrial diameter in the control group was higher than that before treatment, and there was statistical significant difference in the same group ( P<0.05). The level of hs-CRP was lower than that in the control group, the difference was statistically significant ( P<0.05). There were no adverse reactions in both groups. Conclusion:Aspirin combined with atorvastatin has a significant effect in preventing new onset AF after OPCABG. It can reduce the incidence of postoperative AF, shorten the duration of AF, effectively control the inner diameter of left atrium, reduce the degree of postoperative inflammatory reaction, and has no adverse effects. It is worthy of clinical application.

ABSTRACT

Objective:To explore the potential genetic causes of unexplained neonatal encephalopathy.Methods:This retrospective study enrolled 113 infants diagnosed with unexplained neonatal encephalopathy and underwent genetic testing in the Children's Hospital of Hunan Province from January 2019 to May 2021. Perinatal data, clinical manifestations, electroencephalograph, brain MRI findings, genetic information, and prognosis of those patients were analyzed. T-test or Chi-square test were used for data analysis. Results:Of the 113 infants enrolled, 74 (65.5%) were males. The gestational age at birth was (38.6±1.5) weeks, and the birth weight was (2 957±561) g. The most common clinical manifestation was the disturbance of consciousness (83/113, 73.5%), followed by seizures (39/113, 34.5%). There were 38.2% (34/89) of the patients with abnormal brain MRI, and 80.4% (74/92) presented abnormal electroencephalography. Among the 113 infants, 60 (53.1%) had genetic abnormalities, including 48 with single nucleotide variations, eight with copy number variations, and four with chromosome abnormalities. Single nucleotide variations in the 48 patients were classified into syndromic ( n=18, 37.5%), metabolic ( n=16, 33.3%), epileptic ( n=11, 22.9%) and mitochondrial-related genes ( n=3, 6.3%), of which 14 were not included in any database. Among the 103 cases which were successfully followed up until December 31, 2021, 75 (72.8%) had a poor prognosis, including 52 (50.5%) death cases and 23 (22.3%) cases of development retardation. Birth weight and the incidence of seizures in the poor prognosis group were both lower than those in the non-poor prognosis group [(2 876±536) vs (3 254±554) g, t=3.15; 29.3% (22/75) vs 53.6% (15/28), χ2=5.20; both P<0.05], while the incidence of disturbance of consciousness was higher [80.0% (60/75) vs 53.6% (15/28), χ2=7.19, P<0.05]. The proportion of infants with genetic abnormalities in the poor prognosis group was higher than that in the non-poor prognosis group, but the difference was not statistically significant [53.3% (40/75) vs 46.4% (13/28), χ2=0.39, P=0.533]. Conclusions:Genetic abnormality is one of the leading causes of unexplained neonatal encephalopathy. Nucleotide variation is the most common genetic type. Syndromic, metabolic, and epileptic variants are frequently detected in these patients.

ABSTRACT

Anaplastic thyroid cancer (ATC) is the most malignant thyroid cancer with a low incidence but high mortality. ATC is highly aggressive, rapidly progressing, and has poor prognosis. Current treatment options is not efficacious, so there is an urgent need to investigate its pathogenesis to update the treatment and improve the survival rate. Previous studies have found that most ATC can develop from well-differentiated thyroid cancer, and BRAF and RAS mutations are the key driving factors of ATC. TP53, PI3K pathway, PTEN, TERT, SWI/SNF complex Subunit, NF2 and other mutations also play an important role in the occurrence of ATC. Recent studies have found that single gene mutation is often not sufficient to drive the occurrence of ATC, and ATC is usually developed from the accumulation of multiple mutations in well-differentiated thyroid cancer. Therefore, this paper reviews the role of common combined mutations in ATC, deepens the understanding of the pathogenesis, and provides a basis for finding effective therapeutic targets.

ABSTRACT

Objective:To investigate the effect of total anatomical reconstruction (TAR) during robot-assisted radical prostatectomy (RARP) .Methods:The clinical data of 99 patients with RARP performed by a single doctor in our hospital from January 2018 to January 2021 were analyzed retrospectively.There were 38 patients in the TAR+ vesicourethral anastomosis (VUA) group and 61 patients in the VUA group. There were no significant differences between the two groups in the age of patients [ 65.5 (60.8, 71.0) years vs. 66.0 (61.5, 69.0) years], body mass index[ (24.92±2.65) kg/m 2 vs. (25.51±2.80) kg/m 2], prostate volume [28.13 (25.21, 36.53) ml vs. 26.33 (19.75, 47.84) ml], PSA [15.67 (9.02, 31.49) ng/ml vs. 14.58 (9.23, 30.06) ng/ml], neoadjuvant therapy [50.0% (19/38) vs. 63.9% (39/61)], Gleason score (6/7/8/9-10 scores: 8/16/5/9 cases vs. 16/25/9/11 cases) and clinical T stage (T 1/T 2/T 3 stage: 4/29/5 cases vs. 3/53/5 cases)(all P>0.05). The TAR technique was performed as follows. ①The two layers of posterior reconstruction involved the residual Denonvilliers fascia, the striated sphincter and medial dorsal raphe (MDR), and the vesicoprostatic muscle (VPM), the fascia which was 1-2 cm from the cranial side of the bladder neck and MDR. ②The one layer of anterior reconstruction involved detrusor apron, tissues around the urethra and the visceral and parietal layers of the endoplevic fascia. The VUA technique was suturing the bladder neck and urethra consecutively. Perioperative indexes were compared between the two groups. Results:All 99 operations were successfully completed. There were no statistically significant differences between the TAR+ VUA and VUA groups in operation time [ (174.16±47.21) min vs. (188.70±45.39) min], blood loss [ 50 (50, 100) ml vs. 100 (50, 100) ml], incidence of postoperative complications [10.5% (4/38) vs. 14.8% (9/61)], phathological T stage [pT 2/pT 3~4 stage: 25/12 cases vs. 42/19 cases, P=0.895], and the time of indwelling catheter [ 21.0 (19.0, 21.0) d vs. 21.0 (21.0, 21.0) d] (all P>0.05). The difference in postoperative length of stay between the two groups was statistically significant[6.0 (5.0, 6.0) d vs. 7.0 (6.0, 7.5)d, P<0.001]. Follow-up was performed for 1 year after surgery. The recovery rate of urinary continence 3 months after surgery in TAR+ VUA and VUA groups were 86.8% (33/38) vs. 65.6% (40/61), which were statistically significant( P=0.019). There were no significant differences between TAR+ VUA and VUA groups in recovery rate of urinary continence 1 months after surgery [47.4% (18/38) vs. 45.9% (28/61)], 6 months after surgery [94.7% (36/38) vs. 85.2% (52/61)], and 12 months after surgery [94.7% (36/38) vs. 93.4% (57/61)] (all P>0.05). Conclusions:TAR technique has good surgical safety, and can promote recovery of early urinary continence after RARP.

ABSTRACT

Objective:To assess whether urinary incontinence after holmium laser enucleation of the prostate (HoLEP) is associated with membranous urethral length(MUL)on preoperative magnetic resonance imaging.Methods:The data of 96 patients who underwent HoLEP from January 2019 to April 2021 in Peking University Third Hospital were retrospectively analyzed. For all patients, the average age was (70.0±7.7) years old, the average body mass index was (23.9±2.9)kg/m 2, median pre-biopsy PSA was 3.79(2.48, 6.03)ng/ml, the average prostatic volume was (60.5±35.0)ml. 22 patients(22.9%) suffered with diabetes mellitus, and 17 patients(17.7%)had at least one time urinary retention. MUL was measured on MRI as the vertical distance from prostatic apex to the entry of the urethra into the penile bulb. All patients' median MUL was 13(11, 17)mm. The recovery of continence was followed up 2 weeks after HoLEP. The difference of age, body mass index, preoperative PSA, diabetes mellitus, urinary retention, prostate volume and MUL between urinary continence and incontinence group 2 weeks after HoLEP operation. The variables with P<0.1 were included in multivariable logistic regression to analyze the independent risk factors of urinary incontinence after HoLEP were compared. Results:All operations were successfully completed. The continence returned to normal in 72 cases (75.0%) and urinary incontinence existed in 24 cases (25.0%) in 2 weeks after surgery. There were 27 cases (37.5%) in continence group and 16 cases (66.7%) in incontinence group for those aged≥70 years. 21 cases (29.2%) in continence group and 13 cases (54.2%) in incontinence group had prostate volume ≥ 60 ml. There were 30 cases (41.7%) in continence group and 20 cases (83.3%) in incontinence group with MUL<13 mm. χ 2 test showed that age ( P=0.013), prostate volume ( P=0.027) and MUL ( P<0.001) were related to the incontinence after surgery. The age, prostate volume and MUL were included in the multivariate logistic regression analysis. Multiple logistic regression showed that MUL<13 mm( P<0.001) was independent predictor for incontinence after HoLEP. Conclusions:The incidence of urinary incontinence was high 2 weeks after HoLEP. Short MUL, which is less than 13 mm, is significantly associated with delayed recovery of urinary continence after HoLEP.

ABSTRACT

Objective:To investigate the clinical efficacy of triamcinolone acetonide peribulbar injection combined with vitrectomy for rhegmatogenous retinal detachment associated with choroidal detachment (RRD-CD).Methods:This study was a retrospective case series study. Nineteen cases (19 eyes) with RRD-CD who had undergone pars plana vitrectomy at the Dalian No.3 People′s Hospital were analyzed. All the cases received 20 mg triamcinolone acetonide peribulbar injection within 3 to 7 days before surgery. The severity of patient′s uveitis was assessed before and after peribulbar injection of triamcinolone acetonide. Best corrected visual acuity (BCVA) and intra ocular pressure (IOP) before and after surgery, the area of retinal detachment, the rate of retinal reattachment, the rate of recurrent retinal detachment and surgical complications were analyzed. Patients′ blood pressure and blood glucose levels were also monitored.Results:19 patients were followed up for (13.1±1.5)months. The severity of uveitis reduced to different extents compared with preoperative condition. The IOP was (8.73±3.38)mmHg before injection and (10.95±2.46)mmHg after injection, and the difference was statistically significant ( t=-7.571, P=0.027). The choroid detachment range was 4-12(9.37±2.69)sites before injection, and 0-11(4.63±4.10)sites after injection, and the difference was statistically significant ( Z=-3.834, P=0.001). Compared with the preoperative results, the BCVA increased in 12 patients, unchanged in 5 cases and decreased in 2 cases. In the final follow-up of 18 patients with retinal reattachment, 17 eyes underwent a single operation, 2 eyes had recurrent retinal detachment, and 1 eye had retinal reattachment after a second operation. There were no significant difference in blood glucose and blood pressure before and after injection (all P>0.05). There were no other complications besides temporarily elevated IOP and cataract. Conclusions:Vitrectomy combined with triamcinolone acetonide peribulbar injection is effective and safe for patients with RRD-CD.

ABSTRACT

Objective:To investigate the effects of continuous renal replacement therapy (CRRT) on plasma concentration, clinical efficacy and safety of colistin sulfate.Methods:Clinical data of patients received with colistin sulfate were retrospectively analyzed from our group's previous clinical registration study, which was a prospective, multicenter observation study on the efficacy and pharmacokinetic characteristics of colistin sulfate in patients with severe infection in intensive care unit (ICU). According to whether patients received blood purification treatment, they were divided into CRRT group and non-CRRT group. Baseline data (gender, age, whether complicated with diabetes, chronic nervous system disease, etc), general data (infection of pathogens and sites, steady-state trough concentration, steady-state peak concentration, clinical efficacy, 28-day all-cause mortality, etc) and adverse event (renal injury, nervous system, skin pigmentation, etc) were collected from the two groups.Results:A total of 90 patients were enrolled, including 22 patients in the CRRT group and 68 patients in the non-CRRT group. ① There was no significant difference in gender, age, basic diseases, liver function, infection of pathogens and sites, colistin sulfate dose between the two groups. Compared with the non-CRRT group, the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) were higher in the CRRT group [APACHE Ⅱ: 21.77±8.26 vs. 18.01±6.34, P < 0.05; SOFA: 8.5 (7.8, 11.0) vs. 6.0 (4.0, 9.0), P < 0.01], serum creatinine level was higher [μmol/L: 162.0 (119.5, 210.5) vs. 72.0 (52.0, 117.0), P < 0.01]. ② Plasma concentration: there was no significant difference in steady-state trough concentration between CRRT group and non-CRRT group (mg/L: 0.58±0.30 vs. 0.64±0.25, P = 0.328), nor was there significant difference in steady-state peak concentration (mg/L: 1.02±0.37 vs. 1.18±0.45, P = 0.133). ③ Clinical efficacy: there was no significant difference in clinical response rate between CRRT group and non-CRRT group [68.2% (15/22) vs. 80.9% (55/68), P = 0.213]. ④ Safety: acute kidney injury occurred in 2 patients (2.9%) in the non-CRRT group. No obvious neurological symptoms and skin pigmentation were found in the two groups. Conclusions:CRRT had little effect on the elimination of colistin sulfate. Routine blood concentration monitoring (TDM) is warranted in patients received with CRRT.

ABSTRACT

Objective:To evaluate the active monitoring methods and population characteristics of trimetazidine-associated Parkinson's syndrome.Methods:The clinical data of patients with trimetazidine-associated Parkinson's syndrome who received treatment in Liaocheng People's Hospital from January 2019 to December 2020 were retrospectively analyzed using the China Hospital Pharmacovigilance System (CHPS).Results:In 4 883 patients included in the study,167 patients were alarmed by CHPS, of which 26 patients were confirmed positive by manual rechecks. The rate of positive pre-alarming by CHPS was 15.57%. The actual incidence of trimetazidine-associated Parkinson's syndrome was 0.53%. The average age of the 26 patients with Parkinson's syndrome was (75.08 ± 10.79) years. None of the 26 patients had a past history/family history of idiopathic Parkinson's disease. There were 21 patients (80.77%) aged over 65 years, 19 patients (73.08%) with a history of ischemic encephalopathy, 17 patients (65.38%) with positive symptoms in both limbs, 20 patients (76.92%) with abnormal brain CT or MRI findings, and 21 patients (80.77%) with medication doses of 60-70 mg/d. Among the 26 patients, 18 were female patients (69.23%) and 18 were patients with normal renal function (69.23%). The follow-up results showed that trimetazidine administration was not terminated in 14 patients (53.85%), symptoms were not alleviated or worsened in 8 patients (30.77%), and symptoms were alleviated or disappeared in 18 patients (69.23%).Conclusion:The use of CHPS can timely detect trimetazidine-associated Parkinson's syndrome. CHPS has significant advantages over traditional monitoring modes. Age > 65 years and a previous history of ischemic encephalopathy are risk factors for developing trimetazidine-associated Parkinson's syndrome. No history/family history of idiopathic Parkinson's disease, positive Alzheimer's disease symptoms in both limbs and abnormal brain CT and MRI findings contribute to early diagnosis and differentiation of trimetazidine- associated Parkinson's syndrome. Trimetazidine-associated Parkinson's syndrome is more common in women than in men. Trimetazidine-associated Parkinson's syndrome can also occur in a population with normal renal function or under a normal trimetazidine dose condition. Trimetazidine-associated Parkinson's syndrome is relatively rare. Patients with trimetazidine- associated Parkinson's syndrome have low awareness. Because of the difficult diagnosis and serious consequences, there is a need to strengthen research on trimetazidine-associated Parkinson's syndrome.

ABSTRACT

Claudin18.2(CLDN18.2)is a tight junction protein that is overexpressed in a variety of solid tumors such as gastrointestinal cancer and oesophageal cancer.It has been identified as a promising target and a potential biomarker to diagnose tumor,evaluate efficacy,and determine patient prognosis.TST001 is a recombinant humanized CLDN18.2 antibody that selectively binds to the extracellular loop of human Claudin18.2.In this study,we constructed a solid target radionuclide zirconium-89(89Zr)labled-TST001 to detect the expression of in the human stomach cancer BGC823CLDN18.2 cell lines.The[89Zr]Zr-des-ferrioxamine(DFO)-TST001 showed high radiochemical purity(RCP,>99%)and specific activity(24.15±1.34 GBq/μmol),and was stable in 5%human serum albumin,and phosphate buffer saline(>85%RCP at 96 h).The EC50 values of TST001 and DFO-TST001 were as high as 0.413±0.055 and 0.361±0.058 nM(P>0.05),respectively.The radiotracer had a significantly higher average standard uptake values in CLDN18.2-positive tumors than in CLDN18.2-negative tumors(1.11±0.02 vs.0.49±0.03,P=0.0016)2 days post injection(p.i.).BGC823CLDN18.2 mice models showed high tumor/muscle ratios 96 h p.i.with[89Zr]Zr-DFO-TST001 was much higher than those of the other imaging groups.Immunohistochemistry results showed that BGC823CLDN18.2 tumors were highly positive(+++)for CLDN18.2,while those in the BGC823 group did not express CLDN18.2(-).The results of ex vivo biodistribution studies showed that there was a higher distribution in the BGC823CLDN18.2 tumor bearing mice(2.05±0.16%ID/g)than BGC823 mice(0.69±0.02%ID/g)and blocking group(0.72±0.02%ID/g).A dosimetry estimation study showed that the effective dose of[89Zr]Zr-DFO-TST001 was 0.0705 mSv/MBq,which is within the range of acceptable doses for nuclear medicine research.Taken together,these re-sults suggest that Good Manufacturing Practices produced by this immuno-positron emission tomog-raphy probe can detect CLDN18.2-overexpressing tumors.

ABSTRACT

Objective:To investigate the short-term outcomes of totally robotic surgical system and robotic surgical system assisted radical gastrectomy for gastric cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 290 patients who under-went robotic surgical system radical gastrectomy for gastric cancer in the First Affiliated Hospital of Army Medical University from January 2018 to November 2021 were collected. There were 208 males and 82 females, aged 58 (range, 24?84)years. Of the 290 patients, 125 patients undergoing totally robotic surgical system radical gastrectomy combined with reconstruction of digestive tract were divided into the totally robot group, and 165 patients undergoing robotic surgical system radical gastrectomy combined with a small midline incision-assisted reconstruction of digestive tract were divided into the robotic-assisted group. Observation indicators: (1) surgical and postoperative situations; (2) postoperative complications. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Comparison of ordinal data was conducted using the non-parameter rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Surgical and postoperative situations. The operation time, volume of intraoperative blood loss, length of incision, duration of postoperative analgesic using, time to postoperative gastric tube removal, time to postoperative initial water intake, time to postoperative first anal flatus, duration of post-operative hospital stay were (246±43)minutes, (104±51)mL, 4(range, 3?6)cm, (2.2±0.5)days, 36(range, 10?112)hours, 62(range, 32?205)hours, 63(range, 18?138)hours, 8(range, 6?50)days in patients of the totally robot group, versus (296±59)minutes, (143±87)mL, 6(range, 3?13)cm, (3.6±0.7)days, 42(range, 12?262)hours, 90(range, 18?262)hours, 80(range, 16?295)hours, 9(range, 6?63)days in patients of the robotic-assisted group, showing significant differences in the above indicators between the two groups ( t=8.04, 4.42, Z=?13.98, t=18.46, Z=?5.47, ?5.87, ?6.14, ?4.04, P<0.05). (2) Post-operative complications. Cases with systemic related complications and cases with pulmonary infection were 7 and 4 in patients of the totally robot group, versus 31 and 16 in patients of the robotic-assisted group, showing significant differences in the above indicators between the two groups ( χ2=10.86, 4.68, P<0.05). Further analysis showed that there were significant differences in age ≥60 years, body mass index ≥25 kg/m 2, tumor diameter ≥3 cm, TNM staging as stage Ⅲ of cases with postoperative complications between the totally robot group and the robotic-assisted group ( odds ratio=0.44, 0.17, 0.40, 0.31, 95 confidence interval as 0.20?1.00, 0.03?0.88, 0.18?0.89, 0.11?0.84, P<0.05). Conclusion:Totally robotic surgical system radical gastrectomy for gastric cancer is safe and feasible with advantages of minimal trauma and quick recovery, especially for patients as age ≥60 years, body mass index ≥25 kg/cm 2, tumor diameter ≥3 cm and TNM stage Ⅲ in complication controlling.

ABSTRACT

Objective:To explore the role of continuous renal replacement therapy (CRRT) combined with extracorporeal carbon dioxide removal (ECCO 2R) in the treatment of children with respiratory failure. Methods:The clinical data of 12 children with respiratory failure who were treated with CRRT+ECCO 2R in PICU of Jinan Children's Hospital from July 2020 to August 2022 were collected and analyzed retrospectively. The outcomes and the external pipeline usage of the patients were observed, and the blood gas analysis and ventilator parameters before 1 h and after 1, 6, 12 and 24 h of the treatment were compared by one-way ANOVA with LSD post hoc correction. Results:Six patients successfully withdrew from CRRT+ECCO 2R and mechanical ventilation, three patients were transferred to ECMO treatment. Three cases died after voluntary withdrawal of treatment, and two cases died due to treatment failure. The mortality rate was 41.7%. After continuous treatment of CRRT+ECCO 2R for 15 to 112 h, two cases experienced extracorporeal circuit obstruction. After 1 h of treatment, PaCO 2 decreased from (64.67±24.4) mmHg to (49.42±15.54) mmHg, pH increased from (7.28±0.20) to (7.38±0.11), FiO 2 decreased from (0.85±0.13) to (0.78±0.15), PC decreased from (19.42±4.34) cmH 2O to (17.75±4.00) cmH 2O. After 24 h of treatment, PaCO 2 decreased to (39.2±5.55) mmHg, pH increased to (7.41±0.04), FiO 2 decreased to (0.46±0.11), and PC decreased to (13.8±3.36) cmH 2O, and the differences were statistically significant compared with before treatment ( P < 0.05). Conclusions:The combination of CRRT and ECCO 2R therapy can safely substitute for partial lung ventilation/perfusion function, and play a role in protecting right heart function and improving lung-kidney interaction. It can be considered as an option for extracorporeal respiratory, circulatory, and renal support, and consequently has broad prospects.

ABSTRACT

Objective:To compare the quality of Astragali Radix at different harvest time; To revise the content determination indexes of Astragali Radix in Chinese Pharmacopoeia. Methods:An Agilent Eclipse XDB-C18 column (4.6 mm × 150 mm, 5 μm) was used for the determination of saponins with acetonitrile-water solution as mobile phase in a gradient mode. The drift tube temperature of ELSD was 60 ℃; the pressure was 30 psi; the gain was 800 ℃; the flow rate was 1.0 ml/min; the column temperature was 30 ℃; the injection volume was 20 μl; the acetonitrile-0.2% formic acid solution was used as mobile phase for the determination of flavonoids in a gradient mode; the flow rate was 1.0 ml/min; the detection wavelength was 260 nm; the column temperature was 30 ℃; the 10 μl was injected. The limited range as an indicator for determining Astragali Radix content was determined by investigating the extraction method and extraction time of Astragaloside Ⅰ and detecting the content of Astragaloside Ⅰ in 12 batches of Astragali Radix from different origins. The moisture, total ash, and water-soluble extracts in Astragali Radix were determined according to the drying method, total ash determination method, and cold soaking method in the four parts of Chinese Pharmacopoeia (2020 edition), respectively. Results:The content of total saponins in Astragali Radix harvested in spring and autumn in different origins was not significantly different, but the content of total flavonoids was significantly different. Except for H11, the content of Astragaloside Ⅰ in the other batches of Astragali Radix was ≥ 0.05%, so the content limit of Astragaloside Ⅰ was proposed to be≥0.05%. The results of moisture, total ash and water-soluble extracts in the 12 batches of Astragali Radix all meet the requirements in the Chinese Pharmacopoeia. Conclusions:Astragali Radix harvested in autumn is with higher content of active components and better quality. At the same time, this study can provide a reference that the new version of Chinese Pharmacopoeia can revise the Astragaloside Ⅳ in the content determination index of Astragali Radix to Astragaloside Ⅰ .

ABSTRACT

Objective:To investigate the risk factors related to the contrast-induced nephropathy(CIN)occurring after carotid artery stenting(CAS)in patients with carotid artery stenosis.Methods:The clinical data of 137 patients with carotid artery stenosis, who were treated with CAS at Xuanwu Hospital, Capital Medical University during the period from January to Decmber 2021 were retrospectively analyzed. Record demographic characteristics (age, gender, height, weight), history of underlying diseases (hypertension, diabetes, kidney disease, etc.), history of medications, etc. Observe the clinical parameters such as creatinine, blood urea nitrogen, albumin, hemoglobin, hematocrit, degree of stenosis and estimated glomerular filtration rate (eGFR). Measurement data conforming to the normal distribution were expressed as the mean±standard deviation( ± s), and the t-test was used for comparison between groups; the measurement data that does not conform to the normal distribution were expressed as the median (interquartile range) [ M( Q1, Q3)], and the Rank-sum test was used for comparison between groups; the Chi-square test or Fisher exact test was used for comparison of count data between groups. Relevant variables were subjected to univariate analysis, and statistically significant indicators were selected according to the results of univariate analysis to be included in the multivariate Logistic regression analysis. Results:After CAS, a total of 29 patients (21.2%) among the 137 patients developed CIN. Univariate analysis indicated that bilateral carotid artery stenosis, uncontrolled hypertension before surgery, history of angiotensin converting enzyme inhibitor drugs, diabetes mellitus, history of insulin drugs, eGFR<45 mL/(min·1.73 m 2), body weight were the influencing factors associated with the occurrence of CIN after CAS in patients with carotid artery stenting; multivariate regression analysis revealed that the presence of bilateral carotid artery stenosis( OR=4.724, 95% CI: 1.455-15.338, P=0.010), diabetes mellitus( OR=3.451, 95% CI: 1.345-8.858, P=0.010) and eGFR <45 mL/(min·1.73 m 2)( OR=4.582, 95% CI: 1.001-20.971, P=0.050) were the independent risk factors related to the CIN after CAS. Conclusion:Patients with the presence of bilateral carotid artery stenosis, diabetes mellitus or eGFR <45 mL/(min·1.73 m 2) are more likely to develop CIN after CAS.

ABSTRACT

BackgroundMost of the researches on continuous nursing education is from the perspective of patients, and there is a lack of studies on the impact of continuous nursing education on patient caregivers, and the care quality of caregivers is closely related to postoperative rehabilitation status of the patients. ObjectiveTo investigate the effect of continuous nursing education on anxiety relief of caregivers of patients with all-robot coronary artery bypass surgery, and to provide references for improving caregivers' anxiety and promoting patients' recovery. MethodsA total of 120 caregivers of patients with all-robot coronary artery bypass surgery at the First and Sixth Center of 301 Chinese PLA General Hospital were included from January 1, 2021 to December 31, 2022. The caregivers were randomly divided into study group and control group with 60 cases in each group by systematic random sampling method. Before the patient discharge from the hospital, all caregivers received routine nursing education. The study group received continuous nursing education for 4 weeks after patient discharged. Self-rating Anxiety Scale (SAS) was used to evaluate the two groups before and one month after discharge. ResultsOne month after discharge, SAS score in the study group was significantly lower than that in the control group [(57.77±14.08) vs. (70.19±13.60), t=-4.913, P<0.01], and the proportion of SAS score above 60 in the study group was significantly lower than that in the control group (41.67% vs. 75.00%, χ2=-13.714, P<0.01). ConclusionContinuous nursing education may help reduce the level of anxiety in caregivers of patients with all-robot coronary artery bypass surgery.

ABSTRACT

OBJECTIVE@#To observe the effects of electroacupuncture (EA) pretreatment on cardiac function, sympathetic nerve activity, indexes of myocardial injury and GABAA receptor in fastigial nucleus in rats with myocardial ischemia reperfusion injury (MIRI), and to explore the neuroregulatory mechanism of EA pretreatment in improving MIRI.@*METHODS@#A total of 60 male SD rats were randomly divided into a sham operation group, a model group, an EA group, an agonist group and an agonist+EA group, 12 rats in each group. The MIRI model was established by ligation of the left anterior descending coronary artery. EA was applied at bilateral "Shenmen" (HT 7) and "Tongli" (HT 5) in the EA group and the agonist+EA group, with continuous wave, in frequency of 2 Hz and intensity of 1 mA, 30 min each time, once a day for 7 consecutive days. After intervention, the MIRI model was established. In the agonist group, the muscone (agonist of GABAA receptor, 1 g/L) was injected in fastigial nucleus for 7 consecutive days before modeling, 150 μL each time, once a day. In the agonist+EA group, the muscone was injected in fastigial nucleus 30 min before EA intervention. The data of electrocardiogram was collected by PowerLab standard Ⅱ lead, and ST segment displacement and heart rate variability (HRV) were analyzed; the serum levels of norepinephrine (NE), creatine kinase isoenzyme MB (CK-MB) and cardiac troponin I (cTnI) were detected by ELISA; the myocardial infarction area was measured by TTC staining; the morphology of myocardial tissue was observed by HE staining; the positive expression and mRNA expression of GABAA receptor in fastigial nucleus were detected by immunohistochemistry and real-time PCR.@*RESULTS@#Compared with the sham operation group, in the model group, ST segment displacement and ratio of low frequency to high frequency (LF/HF) of HRV were increased (P<0.01), HRV frequency domain analysis showed enhanced sympathetic nerve excitability, the serum levels of NE, CK-MB and cTnI were increased (P<0.01), the percentage of myocardial infarction area was increased (P<0.01), myocardial fiber was broken and interstitial edema was serious, the positive expression and mRNA expression of GABAA receptor in fastigial nucleus were increased (P<0.01). Compared with the model group, in the EA group, ST segment displacement and LF/HF ratio were decreased (P<0.01), HRV frequency domain analysis showed reduced sympathetic nerve excitability, the serum levels of NE, CK-MB and cTnI were decreased (P<0.01), the percentage of myocardial infarction area was decreased (P<0.01), myocardial fiber breakage and interstitial edema were lightened, the positive expression and mRNA expression of GABAA receptor in fastigial nucleus were decreased (P<0.01). Compared with the EA group, in the agonist group and the agonist+EA group, ST segment displacement and LF/HF ratio were increased (P<0.01), HRV frequency domain analysis showed enhanced sympathetic nerve excitability, the serum levels of NE, CK-MB and cTnI were increased (P<0.01), the percentage of myocardial infarction area was increased (P<0.01), myocardial fiber breakage and interstitial edema were aggravated, the positive expression and mRNA expression of GABAA receptor in fastigial nucleus were increased (P<0.01).@*CONCLUSION@#EA pretreatment can improve the myocardial injury in MIRI rats, and its mechanism may be related to the inhibition of GABAA receptor expression in fastigial nucleus, thereby down-regulating the excitability of sympathetic nerve.
