Objective To investigate the relationship between occurrence of unexplained recurrent spontaneous abortion(URSA) and immune function of T lymphocytes. Methods T lymphocyte subsets and CD + 4 T helper subsets (including T helper 1 and T helper 2 cells) in peripheral blood from 30 cases with URSA and 24 healthy women (controls) were detected by enzyme-linked immunospot assay (ELISPOT). Results The percentage of CD + 4 positive T lymphocytes in URSA group was higher than that in the controls (60% vs 45%, P

Objective To study the consistency and complementarity of endoscopic ultrasonography (EUS),white light endoscopy (WLE) and magnifying endoscopy (ME) in diagnosis of ulcerative colitis (UC).Methods We collected 125 cases of UC patients diagnosed by WLE and EUS (including 51 cases of WLE + ME + EUS).According to UC mucosal morphology under WLE and crypt openings under ME,we divided all the cases into several groups and analyzed intestinal wall thickness (TWT) under EUS in each group.Results According to the results of UC inflammation degree under WLE,all patients were divided into four groups: 16 severe cases,46 moderate cases,44 mild,and 19 remission stage.TWT results were (5.903 ± 1.551 ) mm,(4.673 ± 1.235 ) mm,(3.756 ± 1.322 )mm and ( 3.464 ± 0.970) mm,respectively.Differences were significant between any two groups ( P ＜ 0.05 ),except for that between mild and remission groups.According to the results of UC inflammation degree under ME,all patients were divided into six groups: 9 cases of villous-like structure,9 cases of typical coral reef-like structure,8 severe coral reef-like structure,13 regular crypt opening,6 epithelial minimal defect and 6 small yellow spot (SYS).TWT results were (5.701 ±0.941 )mm,(5.518 ±0.581 )mm,(5.181 ±0.751 )mm,(3.763 ±0.659) mm,(3.587 ±0.461 )mm and (2.505 ± 0.330 )mm,respectively.Differences were significant between any two groups ( P ＜ 0.05 ) except for those between epithelial minimal defect and regular crypt opening,typical coral reeflike structure,villous-like and severe coral reef-like structure.EUS results showed SYS (6/6) and regular crypt opening ( 10/13 ) were mostly located in mucosa,while lesions of severe coral reef-like structure (8/8) invaded the muscularis propria.Conclusion EUS shows high consistency with WLE and ME in diagnosis of UC inflammation degree and invasive depth.It could assist and even substitute ME for evaluation.

Objective To compare the efficacy of alfentanil and remifentanil in minimizing the propofol injection pain. Methods A total of 175 adult female patients undergoing gynecological procedures with general anesthesia were randomly divided into four groups.Patients received alfentanil 1mg(2 mL,AL group,n=43),remifentanil 0.01 mg(2 mL,REM1 group,n=43),remifentanil 0.02 mg(2 mL,REM2 group,n=45) or normal saline(2 mL,control group,n=44) 30 seconds prior to propofol administration.Visual analogue scale(VAS) was employed to evaluate the subjective feelings of pain due to propofol injection,and adverse effects were recorded. Results One patient in REM2 group and one patient in control group were excluded due to difficulty in venous catheterization.The injection pain in AL group,REM1 group and REM2 group was significantly less severe than that in control group(P

Objective:To study the influence of Wnt5a gene silence on the proliferation,migration and invasion of lung squamous carcinoma cells.Methods:A recombinant plasmid pHI-siRNA~(Wnt5a-)was constructed and used to deliver small interference RNA (siRNA)targeting Wnt5a in SK-MES-1 cells;the transfected cells were screened to establish a stable transgenic cell line.MTT,cell cycle and Transwell assays were employed to evaluate the effect of Wnt5a gene silence on the proliferation,migration and invasion of lung squamous carcinoma cells.Results:Western blotting assay revealed that Wnt5a was lowly expressed in SK-MES-1~(Wnt5a-)(13.6%).The proliferation index(PI)of transgenic cell line was slightly lower than that of the control cell line([28.3?3.8]% vs[30.5?5.2]%). The migration and invasion capabilities of SK-MES-1~(Wnt5a-)cells were(47.3?9.2)% and(39.7?11.7)% of the control cells, respectively.Conclusion:Low Wnt5a expression can significantly inhibit the migration and invasion capabilities of SK-MES-1 cells, indicating that Wnt5a might be a potential target for gene therapy of lung squamous carcinoma.

Objective:To investigate the association of surrogate indexes of insulin resistance with the risk of nonalcoholic fatty liver disease(NAFLD)and advanced liver fibrosis in newly diagnosed patients with type 2 mellitus.Methods:A total of 429 newly diagnosed type 2 diabetic patients hospitalized in the Department of Endocrinology and Metabolism, Shanghai Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine from June 2018 to June 2020 were included. The patients were divided into NAFLD group( n=263)and non-NAFLD group( n=166)according to the results of abdominal ultrasound, NAFLD patients were divided into advanced liver fibrosis group( n=33)and non-advanced liver fibrosis group( n=230)according to the NAFLD fibrosis score(NFS). The correlation of the triglyceride/high density lipoprotein-cholesterol ratio(TG/HDL-C), triglyceride glucose index(TyG), visceral adiposity index(VAI), triglyceride glucose-body mass index(TyG-BMI), homeostasis model assessment of insulin resistance index(HOMA-IR)with NAFLD and the occurrence of advanced liver fibrosis were analyzed. Results:The prevalence of NAFLD in newly diagnosed type 2 diabetic patients was 61.3%, and the prevalence of advanced liver fibrosis was 12.5%. After adjusting the potential confounders, multivariate logistic regression analysis showed that TG/HDL-C, TyG, VAI, TyG-BMI, and HOMA-IR were independently and positively correlated with NAFLD, and only TyG-BMI was independently and positively correlated with advanced liver fibrosis( OR=1.021, 95% CI 1.009-1.034, P<0.01). The receiver operating characteristic analysis showed that the area under the curue of TyG-BMI was more than those of TG/HDL-C, TyG, VAI and HOMA-IR for predicting the occurrence of NAFLD in newly diagnosed type 2 diabetic patients(0.83 vs 0.73, 0.74, 0.73, 0.67, P<0.01), but had no predictive value for advanced liver fibrosis. Conclusion:TyG-BMI is superior to TG/HDL-C, TyG, VAI and HOMA-IR for predicting the occurrence of NAFLD in newly diagnosed type 2 diabetic patients, and it is also an independent risk factor for advanced liver fibrosis.

ObjectiveTo evaluate the short-term effectiveness of tension-free vaginal tapeobturator system(TVT-O) on the type Ⅰ,Ⅱ stress urinary incontinence(SUI) in the elderly female patients. Methods Elderly female patients (73 cases) with SUI type Ⅰ and Ⅱ were selected in 0.5-3.0 years after TVT-O surgical treatment,and they reached the age over 60 years before TVT-O.Difference of daily life and lower urinary tract symptoms before and after surgery were compared by the incontinence impact questionnaire ( Ⅱ Q-7) and the urogenital distress inventory (UDI-6) through telephone survey.Results Totally 73 patients were followed up successfully,aged 60 to 72 years (mean 64.0±4.5).Preoperative patients' daily life quality such as making housework,activities,entertainment,go-out,social contact and emotion had obviously been affected with a score of 9 to 25 by their own scoring (mean 17.0±6.7).Lower urinary tract symptoms including urgency,frequent urination,movement,leakage of urine volume,odynuria and dysuria were from 8 to 21 (mean 14.0±4.7) scores.Mild urinary frequency was 8.2％ (6 cases).Urinal pad usage was in 71 cases (97.3％)After TVT-O,patients' symptoms improved by their own scoring.The Ⅱ Q-7 scores were ranging from 2 to 13 (mean 6.4±3.2),and lower urinary tract symptoms scores from 1 to 9 (mean 5.4±3.2).Mild urinary frequency after surgery was 1.4 ％ (1 case).The urinary incontinence in 39 cases completely disappeared (53.4 ％ ),urinal pad usage were in 34 cases (46.6 ％ ).18 cases (24.7 ％ ) had suprapubic area pain or discomfort postoperatively.Conclusions TVT-O is an ideal choice for type Ⅰ and Ⅱ SUI in elderly female patients.

Objective:To explore the related risk factors of antepartum depression and anxiety,and to provide the theoretical support for early screening,clinical intervention and prevention of antepartum depression and anxiety.Methods:At the time of 28 weeks of prenatal examination,the Edinburgh Postnatal Depression Scale (EP-DS),Self-Rating Anxiety Scale (SAS)were used to survey 2112 pregnant women who were selected from Maternal and Child Health Hospital of Kunming City.Non conditional logistic regression analysis was used to explore the re-lated risk factors of prenatal depression and anxiety.Results:At the 28 weeks of pregnancy,the detection rate of de-pression symptoms and anxiety symptoms were 25.4% and 6.6%.Logistic regression analysis showed that the risk factors for perinatal depression symptoms were younger age (OR =0.80,95%CI:0.68 -0.94),not stick to work during pregnancy (OR =1.18,95%CI:1.02 -1.36),not satisfied with the living environment (OR =1.50,95%CI:1.23 -1.83),expectations for boys (OR =0.86,95%CI:0.77 -0.96),not only daughter (OR =1.37,95%CI:1.06 -1.76),unplanned pregnancy (OR =1.38,95%CI:1.10 -1.72).The risk factors for perinatal anxiety symp-toms were being not satisfied with the living environment (OR =1.64,95%CI:1.19 -2.26),not harmonious with her husband (OR =2.01,95%CI:1.20 -3.37),unplanned pregnancy (OR =1.50,95%CI:1.05 -2.14).Conclu-sion:It suggests that the pregnant women with younger age,less working during pregnancy,being not satisfied with the living environment,having more expectations for boys,being not only daughter,with unplanned pregnancy are more likely to suffer from antepartum depression;those being not satisfied with living environment,having harmoni-ous relation with her husband,and with unplanned pregnancy are more likely to suffer from antepartum anxiety.

Objective To investigate the performance of MSCT in the diagnosis of metanephric adenoma.Methods The imaging data of 5 cases of metanephric adenoma confirmed by operation and pathology in our hospital were collected and analyzed retrospectively.The location, size, shape, density and enhancement of the lesion were further retrospectively analyzed.Results In the incorporated 5 cases of metanephric adenoma, the male to female ratio of cases was 1:4, all were unilateral, including 2 cases of the right kidney,3 cases of the left kidney,2 cases were located in the upper pole, 2 cases in the polar region, 1 case in the lower pole of the kidney.Maximum diameter of the metanephric adenoma ranged from 2.9 cm to 8.4 cm, with an average value of 4.8 cm.The shape of metanephric adenoma was classified into: round (3 cases) and oval (2 cases).On plain scanning slightly lower density was found in 2 cases, equidensity in 2 cases and slightly higher density in 1 case.Furthermore,1 case had small punctatel calcification in the edge of the lesion,1 case with renal papillary carcinoma.4 cases underwent plain and enhanced scanning,and 1 case plain scanning,in which slight density increase after intravenous enhancement was showed in 3 cases,moderate enhancement in 1 case,more uniform enhancement in 3 cases,uneven enhancement in 1 case,delayed enhancement in 4 cases.Conclusion The characteristic MSCT features of metanephric adenoma have a certain specificity.Preoperative correct understanding is helpful to guide the operation scheme.

Objective To explore the pathologic changes in the brain areas corresponding to specific cognitive function and underlying mechanism of cognitive impairment in patients with epilepsy by DTI study.Methods Forty-four Patients and 20 control subjects received the test of Wechsler Adult Intelligence Scale and the Diffusion-Tensor Imaging examination.Mean diffusivity (MD) and fractional anisotropy (FA) in the normal appearing white matter of interested area were measured.T test was employed to compare the MD and FA between patients and healthy controls,patients with normal and impaired FIQ respectively.The relationships between FIQ and DTI value were analyzed by Bivariate correlations.Results VIQ (100.52?17.63),PIQ (95.10?16.72) and FIQ (98.19?17.76) of the patients with epilepsy were significantly lower than those of health controls (VIQ,PIQ and FIQ were 109.77?13.54,108.11? 12.17 and 109.81?10.57,respectively).Significant reduction of FA in both side of posterior limb of internal capsule (P

OBJECTIVETo study the effects of severe acute pancreatitis (SAP) on absorption kinetic parameters of rhubarb free anthraquinones.

METHODSEleven healthy Beagle dogs were randomly divided into the normal group (n = 6) and the SAP group (n = 5). The SAP animal model was prepared by surgery through portal vein blood channel building to collect blood from normal dogs and dogs with SAP. The free anthraquinones (20 mg/kg) was given by gastrogavage. The concentrations of five anthraquinones (aloe emodin, rhein, emodin, chrysophanol, and physcion) in the blood plasma of the portal vein and the femoral artery were determined using high performance liquid chromatography (HPLC). The kinetic parameters were calculated using MATLAB2007B Software. The half life (t(1/2Ka)), the absorption peak time (Tmax), the peak concentration (Cmax), the area under the curve [AUC(0-infinity)], and the mean residence time (MRT) were calculated using the statistical moment method. The transport velocity of corresponding medicines from the gastrointestinal tract to the blood (ka) was calculated.

RESULTSThere was no difference in the chemical composition absorption type of the portal vein and the femoral artery between the two groups. Aloe emodin could be detected in the portal vein of each animal at each time point, and they were in the quantitative range. Rhein could be detected in the portal vein of each animal at each time point, and they were lower than the quantitative limit at few time points. Emodin and chrysophanol could be detected in the portal vein of partial animals at each time point, and most of them were higher than the quantitative limit. Physcion could be detected only in the portal vein of less animals at few time points. Rhein could be detected in the femoral artery at most time points, but the rhein plasma concentration at most time points were lower than the quantitative limit. Lower concentration of aloe emodin, emodin, and chrysophanol could be detected in the femoral artery at only few time points. Physcion was not detected in the femoral artery. The rhein plasma concentration of the femoral artery and the chrysophanol Cmax of the portal vein at 45 min were higher in the SAP group than in the normal group with statistical difference (P<0.05). There was no statistical difference in the rest indices. The AUC of rhein in the two groups were 59.32% and 66.07% of the total free anthraquinones respectively.

CONCLUSIONSSAP could not obviously affect the absorption kinetics parameters of rhubarb free anthraquinones. The intestinal tract and the liver might possibly play important roles in metabolizing or transforming rhubarb free anthraquinones.
