Objective To investigate the diagnostic value of serum soluble transferrin receptor(sTfR) in children with iron deficiency anemia(IDA).Methods Sixty-three children with microcytic hypochromic anemia were divided into IDA and non-IDA(n-IDA)groups,on which sTfR and other iron metabolism related indexes such as serum ferritin(SF) and serum iron(SI) were measured,and(t-test) between groups and analysis of ROC curve were carried out.Results The mean concentration of sTfR in the group of IDA was above normal value and t-test difference was extremely significant compared with n-IDA group(P

OBJECTIVE To study the HBV-DNA level and its replication with only HBsAb positive for transplantation. METHODS Serial serum samples were studied with the quantitative determination of HBV-DNA by a quantitative PCR assay and determination of HBsAb by ELISA. RESULTS The positive rate of HBV-DNA was 8.4% in the patients with only HBsAb positive and that was 11.11% in the patients who had not been injected with vaccine;the level of HBV-DNA in 11 samples was less than 10~4 copies/ml and five samples showed the amount between 10~4-10~6 copies/ml.The positive rate of HBV-DNA was 8.4% in the patients with only HBsAb positive and that was 11.11% in the patients who had not been injected with vaccine;the level of HBV-DNA in 11 samples was less than 10~4 copies/ml and five samples showed the level between 10~4-10~6 copies/ml. CONCLUSIONS Patients with only HBsAb positive are still infective,which should be paid attention in transplantation.

Objective To analyze the X-ray,CT and MRI findings of synovial tuberculosis,and to evaluate the role of MRI in diagnosing synovial tuberculosis.Methods Fourteen eases of synovial tuberculosis comfirmed by operation and pathology were retrospectively analyzed and summarized. All patients were examined by MRI and X-ray,and CT scans were performed in 3 cases. Results X-ray showed joint swelling(8 cases),articular space narrowing(7 cases),marginal joint erosions(4 cases), and periarticular osteoporosis(9 cases).The joint swelling was detected on CT in all 3 cases,and bony erosion and speckled sequestra were seen in 2 cases.MRI in all of patients showed joint swelling and synovial proliferation in different drgees,demonstrated as heterogeneously low signal on T_1 WI and slight high signal(7 cases)and obvious high signal(6 cases)on T_2WI,and diffuse synovial proliferation was demonstrated as massive and nodular signal in 8 cases.Joint effusion was present in 7 cases as low signal on T_1WI and high signal on T_2 WI.Osseous erosion lesions were seen in 7 cases,and intra-artieular cartilage thinned,partly or mostly disappeared in 11 cases.Periarticular bone marrow edema was found in 7 cases. Conclusion MRI was superior to X-ray and CT in the diagnosis and differential diagnosis of synovial tuberculosis.

Objective To investigate the radiosensitization effects of the combination treatment of clioquinol (CQ) and zinc on human cervical cell line HeLa in vitro.Methods Cells were divided into the 4 groups:controls,drug,radiation,and combined drug and radiation group.Cytotoxic effect of CQ and zinc on cell viability was determined by CCK-8 assay.Radiosensitization effect of CQ and zinc on HeLa cells was detected by colongenic assay,and the single-hit multi-target model was used to stimulate the doseresponse curve of survival and to calculate radiosensitization parameters.The cell cycle and apoptosis of HeLa cells were analyzed with flow cytometry.Luciferase reporter assay was used to study NF-κB activity of HeLa cells.Results The combination of CQ and zinc inhibited cell growth in a dose-dependent manner (F =188.00,P ＜ 0.01).The mean lethal dose was 3.16 and 2.04 Gy for radiation group and combined drug and radiation group,respectively,and hence the SER was 1.55.Compared with the radiation group,the ratio of G2-phase cells in the combined drug and radiation group decreased(t =10.39,P ＜ 0.05),the apoptosis rate increased at 24 h post-irradiation (t =5.64,P ＜ 0.01),and the NF-κB activity decreased (t =21.42,P ＜ 0.05).Compared to the control group,the NF-κB activity increased in the radiation group(t=6.23,P＜0.05),but decreased in the drug group(t =12.48,P＜0.05).Conclusions The combination of CQ and zinc could increase the radiosensitivity of HeLa cells by decreasing the ratio of G2-phase cells,increasing apoptosis and the inhibiting of NF-κB activity.

Objective To observe the expression of estrogen receptor(ER)? and ER? in the vaginal wall of women with anterior vaginal prolapse,and to investigate the relationships of ER subtypes with the development of pelvic organ prolapse(POP).Methods Seven premenopausal women and 33 postmenopausal women with anterior vaginal prolapse who underwent surgery in our hospital from July 1999 to July 2004 were analyzed.Nine premenopausal and 8 postmenopausal women with squamous carcinoma of cervix who underwent surgery served as controls.The expression of ER? and ER? in squamous epithelium (SE),lamina propria(LP)and muscular layer(ML)of anterior vaginal wall were studied by immunohistochemical staining.Results(1)Both ER? and ER? were expressed in SE,LP,ML of vaginal wall of premenopausal and postmenopausal women.(2)The expression of ER? was not significantly different in premenopausal and postmenopausal women;the expression of ER? was not significantly different in premenopausal and postmenopausal women with POP;however,it was decreased in postmenopausal women without POP(P

Objective: To explore the association of hypertriglyceridemic waist phenotype ( HTGW ) with impaired fasting glucose ( IFG ) and diabetes, so as to provide reference for the early prevention and control of diabetes. Methods: The survey was conducted among 35 to 75-year-old residents in 8 project sites in Jiangsu Province from 2015 to 2019. The information about demography and lifestyle was collected by the general information questionnaire and the primary screening questionnaire from the National Center for Cardiovascular Diseases; waist circumference, height, weight, triglyceride, high-density lipoprotein cholesterol, total cholesterol and fasting plasma glucose were measured. The multinomial logistic regression model was employed to analyze the association of HTGW with IFG and diabetes. Results: A total of 118 383 subjects were included, among whom 21 851 cases of HTGW, 27 245 cases of IFG and 22 899 cases of diabetes were identified, with the prevalence of 18.46%, 23.01% and 19.34%. The multinomial logistic regression analysis showed HTGW was statistically associated with IFG ( OR=1.414, 95%CI: 1.343-1.489 ) and diabetes ( OR=2.216, 95%CI: 2.098-2.341 ). Conclusion HTGW is associated with IFG and diabetes, which make it possible to be an indicator for screening and assessment of glucose abnormality in middle-aged and elderly population.

Objective To observe the effects of fosinopril(FOS),a new generation angiotensin-converting enzyme inhibitor(ACEI),on protein and mRNA expression of transforming growth factor-?_1(TGF-?_1) of rat glomerular mesangial cell(GMC) induced by lipopolysaccharide(LPS);to demonstrate the preventive mechanism against glomerular sclerosis by applying FOS.Methods The cultured GMC in classic way were divided into 3 groups:control group;LPS group;LPS+FOS group.TGF-?_1 concentration in GMC supernatant fluid was detected by ELISA;TGF-?_1 mRNA expression was determined by semiquantitative real-time RT-PCR.Results LPS group was obviously higher than control groups in TGF-?_1 secretion and mRNA expression,while LPS+FOS group decreased distinctively in TGF-?_1 secretion and mRNA expression compared with LPS group.Conclusions FOS has obviously inhibited on TGF-?_1 expression of rat GMC both at protein level and mRNA level,which reveals that it may be an important mechanism by FOS on restraining the development of glomerulosclerosis.
