ABSTRACT

ABSTRACT Introduction: This study aimed to compare the early postoperative outcomes of right anterior thoracotomy minimally invasive aortic valve replacement (RAT-MIAVR) surgery with those of median full sternotomy aortic valve replacement (MFS-AVR) approach with the goal of identifying potential benefits or drawbacks of each technique. Methods: This retrospective, observational, cohort study included 476 patients who underwent RAT-MIAVR or MFS-AVR in our hospital from January 2015 to January 2023. Of these, 107 patients (22.5%) underwent RAT-MIAVR, and 369 patients (77.5%) underwent MFS-AVR. Propensity score matching was used to minimize selection bias, resulting in 95 patients per group for analysis. Results: After propensity matching, two groups were comparable in preoperative characteristics. RAT-MIAVR group showed longer cardiopulmonary bypass time (130.24 ± 31.15 vs. 117.75 ± 36.29 minutes, P=0.012), aortic cross-clamping time (76.44 ± 18.00 vs. 68.49 ± 19.64 minutes, P=0.004), and longer operative time than MFS-AVR group (358.47 ± 67.11 minutes vs. 322.42 ± 63.84 minutes, P=0.000). RAT-MIAVR was associated with decreased hospitalization time after surgery, lower postoperative blood loss and drainage fluid, a reduced incidence of mediastinitis, increased left ventricular ejection fraction, and lower pacemaker use compared to MFS-AVR. However, there was no significant difference in the incidence of major complications and in-hospital mortality between the two groups. Conclusion: RAT-MIAVR is a feasible and safe alternative procedure to MFS-AVR, with comparable in-hospital mortality and early follow-up. This minimally invasive approach may be a suitable option for patients requiring isolated aortic valve replacement.

ABSTRACT

Objective: To evaluate the value of nasal nitric oxide (nNO) measurement as a diagnostic tool for Chinese patients with primary ciliary dyskinesia (PCD). Methods: This study is a retrospective study. The patients were recruited from those who were admitted to the respiratory Department of Respiratory Medicine, Children's Hospital of Fudan University from March 2018 to September 2022. Children with PCD were included as the PCD group, and children with situs inversus or ambiguus, cystic fibrosis (CF), bronchiectasis, chronic suppurative lung disease and asthma were included as the PCD symptom-similar group. Children who visited the Department of Child health Care and urology in the same hospital from December 2022 to January 2023 were selected as nNO normal control group. nNO was measured during plateau exhalation against resistance in three groups. Mann-Whitney U test was used to analyze the nNO data. The receiver operating characteristic of nNO value for the diagnosis of PCD was plotted and, the area under the curve and Youden index was calculated to find the best cut-off value. Results: nNO was measured in 40 patients with PCD group, 75 PCD symptom-similar group (including 23 cases of situs inversus or ambiguus, 8 cases of CF, 26 cases of bronchiectasis or chronic suppurative lung disease, 18 cases of asthma), and 55 nNO normal controls group. The age of the three groups was respectively 9.7 (6.7,13.4), 9.3 (7.0,13.0) and 9.9 (7.3,13.0) years old. nNO values were significantly lower in children with PCD than in PCD symptom-similar group and nNO normal controls (12 (9,19) vs. 182 (121,222), 209 (165,261) nl/min, U=143.00, 2.00, both P<0.001). In the PCD symptom-similar group, situs inversus or ambiguus, CF, bronchiectasis or chronic suppurative lung disease and asthma were significantly higher than children with PCD (185 (123,218), 97 (52, 132), 154 (31, 202), 266 (202,414) vs. 12 (9,19) nl/min,U=1.00, 9.00, 133.00, 0, all P<0.001). A cut-off value of 84 nl/min could provide the best sensitivity (0.98) and specificity (0.92) with an area under the curve of 0.97 (95%CI 0.95-1.00, P<0.001). Conclusions: nNO value can draw a distinction between patients with PCD and others. A cut-off value of 84 nl/min is recommended for children with PCD.

ABSTRACT

Objective:To explore the clinical outcomes of intraoperative fluoroscopy on femoral tunnel placement in treating professional snow sports athletes with anterior cruciate ligament (ACL) injury.Methods:A retrospective case series study was used to analyze the clinical data of 13 professional snow sports athletes with ACL injury treated in the National Institute of Sports Medicine, General Administration of Sport of China from January 2016 to January 2019. There were 5 males and 8 females, aged 16-27 years [(18.5±3.0)years]. Intraoperative lateral fluoroscopy combined with quadrant method was performed for the accurate femoral tunnel placement in single-bundle ACL reconstruction by using autologous hamstring tendon in all patients. KT1000 side-to-side difference (KT1000-ssd), pivot shift test, International Knee Documentation Committee (IKDC) subjective score, Lysholm score, Marx activity scale and maximum extension and flexion resistance ratio of the involved and uninvolved knee were compared before operation (or before injury) and at 3, 6, 12 and 24 months after operation. Whether returning to the field, time taken in returning to the field and re-injury were recorded at each follow-up visit. ACL graft signal intensity ratio (SIR) in MRI of the involved knee was evaluated at postoperative 24 months.Results:All patients were followed up for 24-33 months [(25.8±2.7)months]. There were 7 patients with KT1000-ssd degree I, 5 with degree II and 1 with degree III before operation, compared to 12 patients with KT1000-ssd degree 0 and 1 with degree I at 3 and 6 months after operation and 13 patients with KT1000-ssd degree 0 at 12 and 24 months after operation. The pivot shift test was grade I in 8 patients and grade II in 5 before operation, compared to 11 patients with degree 0 and 2 with degree I at 3 months after operation and 12 patients with degree 0 and 1 with degree I at 6, 12 and 24 months after operation. IKDC subjective score was (68.0±4.3)points, (84.7±7.9)points, (94.6±3.3)points and (96.5±1.8)points at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, IKDC subjective score was significantly improved compared to the preoperative (48.3±25.0)points (all P<0.01). The Lysholm score was (63.4±6.6)points, (80.1±6.5)points, (93.8±4.6)points and (96.5±2.4)points at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, the Lysholm score was significantly improved compared to the preoperative (47.5±29.4)points (all P<0.01). The Marx activity scale was (7.4±0.5)points, (13.8±0.7)points, (14.6±0.8)points and (15.0±0.7)points at postoperative 3, 6, 12 and 24 months, respectively, significantly lower than (16.0±0.0)points before the injury (all P<0.01). The maximum extension resistance ratio of the involved and uninvolved knee was 0.60±0.10, 0.85±0.08, 0.91±0.06 and 0.97±0.04 at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, the maximum extension resistance ratio of the involved and uninvolved knee was significantly increased compared to the preoperative 0.57±0.18 (all P<0.01).The maximum flexion resistance ratios of involved and uninvolved knee were 0.64±0.09, 0.82±0.06, 0.89±0.04 and 0.94±0.06 at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, the maximum flexion resistance ratio of the involved and uninvolved knee was significantly increased compared to the preoperative 0.60±0.12 (all P<0.01). Thirteen athletes returned to the field within 12 months after operation with the time taken in returning to the field ranging from 5-12 months [(8.7±1.9)months]. There was no ACL re-injury at postoperative 24 months. The ACL graft SIR in MRI of the involved knee was 1.80±0.20 at postoperative 24 months. Conclusion:Intraoperative fluoroscopy on femoral tunnel placement in the treatment of professional snow sports athletes with ACL injury can significantly improve the knee joint stability, subjective function, sports performance and muscle strength within 6 months, and can help them return to the field within 12 months, and accelerates graft healing.

ABSTRACT

OBJECTIVE@#To establish 10-color fluorescent antibody combination panels for the detection of minimal residual disease (MRD) of acute myeloid leukemia (AML) in our laboratory and discuss the value of clinical application.@*METHODS@#According to the antigen expression characteristics of leukemia cells of incipient AML patients, MRD in bone marrow were detected by multiparameter flow cytometry, and the test results were compared with both bone marrow cell morphology and PCR results, then 10-color fluorescent antibody combination panels in our lab for MRD detection was determined.@*RESULTS@#The immunophenotypic characteristics of 392 incipient patients with AML in the First Affiliated Hospital of Zhengzhou University were analyzed, among them 357 (91.07%) cases showed abnormal immunophenotypes, which mainly included cross-lineage expression, cross-stage expression, deficiency of antigen expression or abnormal antigen intensity and other abnormal expression. The 10-color fluorescent antibody combination panels established according to abnormal immunophenotypic characteristics of leukemia cells were applied for detecting MRD in 156 patients with AML, the positive rate (43.6%) was higher than 26.8% of morphology, and the results were highly consistent with PCR detection results (96.49%), moreover, the recurrence rate of MRD positive patients (86.96%) was significantly higher than 5.75% of MRD negative patients. Therefore, this method could truly reflect the load of leukemia cells and prompt change of disease condition.@*CONCLUSION@#Multiparameter flow cytometry can detect various abnormal immunophenotypes of AML. The 10-color fluorescent antibody combination panels in our lab based on the characteristics of antigens expression in leukemia cells can well detect MRD of leukemia cells, so as to predict relapse and provide basis for clinical treatment.

ABSTRACT

Objective: To assess the clinical features and treatment outcomes in patients with primary ovarian squamous cell carcinoma (POSCC). Methods: Fifteen patients with primary ovarian squamous cell carcinoma diagnosed from January 2009 to December 2018 in Cancer Hospital of the University of Chinese Academy of Sciences were collected. The expression of p16, hMLH1, hMSH2, hMSH6 and PMS2 in POSCC was detected by immunohistochemistry, and the status of high-risk human papillomavirus (HPV) by RNAscope test. Results: Squamous cell carcinoma with different degrees of differentiation was found in 15 cases, including three cases with high differentiation and 12 cases with medium to low differentiation. There were four cases with in situ squamous cell carcinoma, four cases with teratoma, one case with endometrial carcinoma/atypical hyperplasia, and one case with endometriosis. p16 was expressed in five cases (5/15), indicating coexisting high-risk HPV infection. There was no high-risk HPV infection in the remaining 10 cases, and p16 staining was negative. There was no deficient mismatch repair protein in all cases. The overall survival time (P=0.038) and progression free survival (P=0.045) of patients with high-risk HPV infection were longer than those without HPV infection. Conclusions: POSCC is more commonly noted in postmenopausal women and often occurs unilaterally. Elevated serological indexes CA125 and SCC are the most common finding. Morphologically, the tumors show variable degrees of differentiation, but the current data suggest that the degree of differentiation cannot be used as an independent prognostic index. High-risk HPV infection may be associated with the occurrence of POSCC, and that the prognosis of POSCC patients with HPV infection is better than that of patients without infection.

ABSTRACT

【Objective】 To investigate the prevalence of occult hepatitis C virus infection (OCI) in Shaanxi blood donors and characterize the occult hepatitis C virus in this cohort. 【Methods】 Between July and September of 2019, 112, 117, 46, and 75 blood samples were obtained from eligible donors, alanine aminotransferase (ALT) elevated donors(ALT>50 U/L), hepatitis B virus surface antigen (HBsAg) positive donors, and anti-hepatitis C virus (anti-HCV) positive donors, respectively. Peripheral blood lymphocytes (PBMCs) were isolated from all the samples. HCV 5′UTR was amplified from total RNA of PBMCs using reverse transcription nested PCR (RT-Nested PCR) to detect the infection status of OCI in blood donors. HCV RNA core/E2 region was amplified from HCV RNA positive samples with RT-Nested PCR to determine HCV genotypes and subtypes via sequencing. 【Results】 Two (2.67%, 2/75) cases of OCI were identified in anti-HCV positive samples, 1(0.85%, 1/117) case of OCI was identified in abnormal ALT samples, and all OCI were genotyped as 1b. OCI was not found in HBsAg positive and eligible blood donors. 【Conclusions】 Our findings suggest that OCI does exist among Shaanxi blood donors and that ALT may be useful in diagnosing OCI.

ABSTRACT

Objective: To compare the value of 25-hydroxyvitamin D3 (25-(OH)D3) with other clinical parameters in the prediction and diagnosis of eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP). Methods: Eligible chronic rhinosinusitis with nasal polyps (CRSwNP) patients and healthy subjects in the Affiliated Hospital of Guizhou Medical University from January to April of 2021 were included for this study. The age, gender, past history and other basic characteristics of all subjects were recorded. The CRSwNP patients were classified into ECRSwNP and non-eosinophilic chronic rhinosinusitis with nasal polyps (nECRSwNP) endotypes by the percentage of tissue eosinophils. Serum 25-(OH)D3 levels measurements were performed in all subjects. Paranasal sinus CT scans, blood eosinophil counts, and determination of total immunoglobulin E (total IgE), Th1/Th2 plasma cytokines and nasal nitric oxide (nNO) levels were performed before surgery. Logistic regression analysis was used to evaluate the related factors of ECRSwNP. Receiver operating characteristic (ROC) curves was used to evaluate the predictive potential of the clinical parameters. Results: One hundred and twenty-seven CRSwNP patients and 40 healthy subjects were recruited, including 74 males and 93 females of the patients, with the age of (38.73±13.05) years. In patients with ECRSwNP, serum 25-(OH)D3 levels were significantly lower than those in nECRSwNP patients ((26.14±4.58) ng/ml vs (35.71±7.86) ng/ml, t=-8.564, P<0.01). The prevalence of asthma, prevalence of allergic rhinitis, peripheral blood eosinophil counts, total IgE levels, nNO levels and CT scores ratio for ethmoid sinus and maxillary sinus (E/M ratio) of ECRSwNP patients were significantly higher than those in nECRSwNP patients (all P<0.05). However, there was no significant difference in Th1/Th2 cytokines levels between the histological types of CRSwNP (all P>0.05). Among the predictive indicators, 25-(OH)D3 had the highest predictive value, with ROC area under curve (AUC) value of 0.882. The best cut-off point of 28.5 ng/ml for 25-(OH)D3 demonstrated a sensitivity of 0.871 and a specificity of 0.762 for ECRSwNP. Conclusion: Measurement of serum 25-(OH)D3 level may be used as an effective method to distinguish between ECRSwNP and nECRSwNP.

ABSTRACT

Rhododendron molle G. Don is first recorded in Shengnong's Herbal Classic, and its fruits, which are termed as Liuzhouzi, are often used to treat rheumatoid arthritis in Chinese folk. During our ongoing investigation to develop a safer and potential new arthritis therapy, a process for the preparation of diterpenoid fraction from Rhododendron mollefruits was established. In order to evaluate the main components and the anti-rheumatoid arthritis effect of the diterpenoid fraction, phytochemical and pharmacological experiments were used. As the result, the main components of diterpenoid fraction were identified as rhodojaponin III (1), rhodojaponin VI (2), 2-O-methylrhodojaponin (3), and 5'-β-D-glucopyranosy-loxyjasmonic acid (4). These four components constitute greater than 95% of diterpenoid fraction using area normalization method of HPLC-ELSD. The results of CIA rat experiment showed that high dose of diterpenoid fraction (0.6 mg·kg

ABSTRACT

Objective:To compare the clinical effects of two enteral nutritional emulsions, TP-HE and TPF, in elderly patients with severe pneumonia.Methods:This was a randomized study with contemporaneous controls.A total of 56 elderly patients over 65 years old who met the diagnostic criteria for severe pneumonia and were receiving insulin were enrolled.They were randomly divided into the observation group(n=28, enteral TPF-HE at a uniform rate through a nasogastric tube)and the control group(n=28 cases, enteral TPF at a uniform rate through a nasogastric tube). The total daily energy supply was calculates based on the ideal weights of patients.Prealbumin(PA), serum albumin(ALB), body mass index(BMI)and hemoglobin(Hb)were continuously measured at 1, 2, 3, 4, 5, 6 and 7 days after treatment.The effects of the enteral nutritional emulsions in elderly patients with severe pneumonia were analyzed by using repeated measures analysis of variance in a general linear model.Results:There was no significant difference in PA(244.5±55.1)mg/L vs.(237.8±40.4)mg/L, ALB(37.6±5.6)mg/L vs.(38.3±5.5)mg/L, BMI(21.9±0.2)kg/m 2vs.(22.4±0.2)kg/m 2)or Hb(104.4±26.8)mg/L vs.(103.6±25.6)mg/L between the TP-HE group and the TPF group before admission( P>0.05). The energy received from the enteral nutritional emulsions was not significantly different between the TP-HE group and the TPF group(79.8±4.8)kcal/d vs.(79.3±6.6)kcal/d( P>0.05). PA and serum ALB levels had significant differences between the TP-HE group and the TPF group at 1, 2, 3, 4, 5, 6 and 7 days after treatment( P<0.01 or 0.05). Increases in PA and serum ALB levels varied at certain time points between the TP-HE group and the TPF group.Hb levels had no significant difference at 1 and 2 days( P>0.05), but were significantly different at other time points between the two groups( P<0.01). There was no significant difference in BMI between the two groups( F=1.709, P>0.05). Conclusions:Both of the enteral nutrition emulsions can improve PA, ALB and Hb levels, with TP-HE offering more significant effects on PA, ALB and Hb levels.There is no difference in BMI at any time point whether patients receive TP-HE or TPF.

ABSTRACT

Objective: To explore the impact of bundle branch block (BBB) on acute coronary syndrome (ACS) prognosis in patients after percutaneous coronary intervention (PCI). Methods: A total of 6 429 ACS patients received PCI in our hospital from 2013-01 to 2013-12 were enrolled. According to BBB diagnosis at discharge, the patients were divided into 2 groups: BBB group, n=159 and Non-BBB group, n=6 270. The incidences of 2-year major adverse cardio and cerebral-vascular events (MACCE) including all-cause death, cardiac death, myocardial infarction, revascularization, in-stent thrombosis and stroke were compared between 2 groups; relationship between existing BBB and clinical outcomes was assessed. Results: Compared with Non-BBB group, BBB group had the elder age (62.97±11.37) years vs (58.26±10.36) years, lower BMI (25.31±3.02) vs (25.89±3.20), decreased glomerular filtration rate (86.89±16.15)ml/min vs (91.05±15.53)ml/min and LVEF (59.27±9.86)% vs (62.37±7.36) %, all P<0.05; other baseline condition, angiographic and interventional features were similar between 2 groups, all P>0.05. During 2-year follow-up period, compared with Non-BBB group, BBB group showed the higher incidences of cardiac death (2.5% vs 0.7%) and in-stent thrombosis (3.1% vs 0.8%), both P<0.05; other incidences of MACCE were similar between 2 groups, all P>0.05. With adjusted propensity score matching, 2-year incidence of MACCE was similar between 2 groups, P>0.05; 2-year incidences of MACCE in BBB group including LBBB and RBBB were similar to Non-BBB group, P>0.05. Cox regression analysis revealed that BBB was not related to ACS prognosis after PCI. Conclusion: BBB was not an independent risk factor for long-term MACCE occurrence in ACS patients after PCI.

ABSTRACT

BACKGROUND: Previous studies have found that polygonatum sibiricum polysaccharide (PSP) exhibits anti-osteoporosis effect, but its therapeutic effect in ovariectomized osteoporotic rats and the molecular mechanisms are poorly understood. OBJECTIVE: To investigate the effect of administration of PSP on the bone microstructure, bone mineral density as well as osteoblast- and osteoclast-related gene expression in rats. METHODS: Twenty-five infertile female Sprague-Dawley rats aged 3 months were randomly allotted into five groups (n=5 per group): sham operation (same volume normal saline), model, zoledronate (0.2 mg/kg?d), high-dose PSP (800 mg/kg?d) and medium-dose PSP (400 mg/kg?d) groups. All rats were subjected to ovariectomy except sham operation group. The administration was intragastrically given every 2 days beginning at 7 days after modeling and lasted 12 weeks. Then, the rats were sacrificed, and the uterus was weighed. The bilateral tibias were removed, one side for histomorphometric analysis by micro-CT, and the other one for RNA detection by qualified PCR. RESULTS AND CONCLUSION: Compared with the sham operation group, the rat body mass in the model group was significantly increased and the weight of uterus was significantly decreased (P < 0.05). Compared with the model group, zoledronate and high-dose PSP could significantly alleviate the excessive increase in body mass (P < 0.05). The bone mineral density in the model group was decreased by 63% compared with the sham operation group (P < 0.01), Compared with the model group, after 12-week high-dose PSP and zoledronate administration, the bone mineral density was increased by 44% and 38%, respectively (P < 0.01); the trabecular bone volume fraction and trabecular number rose significantly(P<0.05),while the trabecular separation decreased significantly(P<0.05).In vivo,PSP could significantly promote the expression levels of osteoblast-related genes (alkaline phosphatase, RUNX2, Col1a1 and osteocalcin), and significantly inhibit the expression levels of osteoblast-related genes (ACP5 and CTSK) (P < 0.05). These results imply that high-dose PSP can reduce bone loss and decrease of bone mineral density, improve the destruction of bone microstructure, as well as promote osteoblast-related genes but inhibit osteoclast-related gene mRNA expression in the ovariectomized rats.

ABSTRACT

<p><b>BACKGROUND</b>The ST-segment elevation myocardial infarction (STEMI) patients due to stent thrombosis (ST) remain a therapeutic challenge for a clinician. Till date, very few researches have been conducted regarding the safety and effectiveness of primary percutaneous coronary intervention (PCI) with second-generation drug-eluting stents (DES) for STEMI caused by very late ST (VLST). This retrospective study evaluated the safety, efficacy, and outcomes of primary PCI with second-generation DES for STEMI due to VLST compared with primary PCI for STEMI due to de novo lesion.</p><p><b>METHODS</b>Between January 2007 and December 2013, STEMI patients with primary PCI in Fuwai Hospital had only second-generation DES implanted for de novo lesion (558 patients) and VLST (50 patients) were included in this retrospective study. The primary end points included cardiac death and reinfarction. The secondary end points included cardiac death, reinfarction, and target lesion revascularization. Continuous variables were expressed as mean (standard deviation) or median (interquartile range) and compared by Student's t- test or Mann-Whitney U-test as appropriate. Categorical variables were expressed as counts and percentages, and comparison of these variables was performed with Chi-square or Fisher's exact test. A two-tailed value of P < 0.05 was considered statistically significant for all comparisons. Statistical analyses were performed by SAS software (version 9.4, SAS Institute Inc., Cary, USA) for Windows.</p><p><b>RESULTS</b>In-hospital primary end point and the secondary end point were no significant differences between two groups (P = 1.000 and P = 1.000, respectively). No significant differences between two groups were observed according to the long-term primary end point and the secondary end point. Kaplan-Meier survival curves showed no significant difference between the two groups in the primary end point and the secondary end point at 2 years (P = 0.340 and P = 0.243, respectively). According to Cox analysis, female, intra-aortic balloon pump support, and postprocedural thrombolysis in myocardial infarction flow 3 were found to be independent predictors for long-term follow-up.</p><p><b>CONCLUSION</b>Primary PCI with second-generation DES is a reasonable choice for STEMI patients caused by VLST.</p>

ABSTRACT

OBJECTIVE:To prepare total flavonoids of Hippophae rhamnoides(TFH)-PVP K30 solid dispersion,and to char-acterize and study its in vitro dissolution. METHODS:Solvent method was used to prepare TFH-PVP K30 solid dispersion with dif-ferent drug-loading ratio of 1:1,1:2,1:3,1:4,1:5;single factor test was designed to screen drug-loading ratio using dissolution parameter Td as index;orthogonal test was designed to optimize ultrasonic time,temperature of water bath and drying time for prep-aration technology using in vitro dissolution rate as index,and then validated. SEM,DSC and FT-IR were used to characterize sol-id dispersion. RESULTS:Td of TFH-PVP K30 solid dispersion was the lowest when drug-loading ratio was 1:3. Optimal technolo-gy was ultrasonic time 10 min,temperature of water bath 60 ℃ and drying time 12 h. 90 min accumulative dissolution rate of pre-pared TFH-PVP K30 solid dispersion was 90.22% in average(RSD=1.74%,n=3). The results of SEM,DSC and FT-IR showed that the drug as amorphous form dispersed in the PVP K30,the formation of hydrogen bond of the both. CONCLUSIONS:TFH-PVP K30 solid dispersion is prepared successfully,and in vitro dissolution rate of it is improved significantly.
