Purpose cerebral venous sinus thrombosis (CVST) has no specific manifestations in clinic, it is often misdiagnosed and the treatment is delayed. This paper aims to evaluate magnetic resonance venography (MRV) in the detection of CVST by meta-analysis. Materials and Methods The articles concerning the diagnosis of CVST by using MRV were searched in the databases such as Cochrane Library, PubMed, Embase, Web of Science, CBM, VIP, Wanfang and CNKI. The QUADAS items were used to evaluate the quality of the included studies. The results were analyzed with software Metadisc1.4 and RevMan 5.0. The pooled weighted sensitivity, specificity, and the diagnostic odds ratio were calculated, and complete summary receiver operating characteristic curve (SROC) was drawn. Results Twelve studies of eight articles met the inclusion criteria. The pooled sensitivity, specificity, diagnostic odds ratio and area under SROC curve for the MRV were 0.86 (0.80-0.91), 0.87 (0.83-0.93), 29.65 (12.48-70.47), and 0.9125, respectively. Conclusion MRV can be used as an effective method with its high value in the diagnosis of CVST.

Objective To evaluate the association between maternal serum levels of vitamin B12 and folate and neural tube defects (NTD) in Shanxi Province which with the extremely high prevalence of NTD in China. Methods A case-control study was conducted in five counties of Shanxi Province, China. Maternal concentrations of vitamin B12 and folate [expressed as G (P5-P95)]in NTD-affected pregnancies were dichotomized at a cut-off of 10th percentile of the mean values of control women to calculate the risk of NTD for the lower level group. Results The mean levels of serum vitamin B12 and folate in the NTD pregnancies were significantly lower than in the control [vitamin B12 83. 8 pmol/L(30. 5-209. 1) pmol/L vs 102. 6 pmol/L(51. 9-269. 7) pmol/L, P<0. 05; folate:10. 5 pmol/L(4. 4-24. 5) nmol/L vs 12. 9 pmol/L(6. 3-32. 7) nmol/L, P<0. 01]. In cases complicated with spina bifida, lower maternal serum vitamin B12 and folate levels were detected compared with the control group. While, in those complicated with anencephaly, only lower levels of maternal folate were shown. There was no statistical significance in maternal serum concentrations of vitamin B12 and folate between those cases with encephalocele and controls. Higher risk of NTDs were found in pregnant women with lower level of vitamin B12 and folate (AOR = 2. 58, 95% CI: 1. 20-5. 51; AOR= 2. 76, 95%CI: 1. 30-5. 87). Conclusions Deficiency or insufficiency of folate or vitamin B12 is associated with the increased risk of NTD, especially in high risk population.

Early small hepatocellular carcinoma (SHCC) can be cured by surgery and interventional operation to improve the survival rate of paitents,so the accurate diagnosis of SHCC is of great significance.Presently,the dynamic contrast-enhanced MR scan could only obtain single arterial phase imaging by single breath hold,and it had breathing motion artifact because of the long scanning time.The early arterial transient enhancement of SHCC was easy to be misdiagnosed.The CAIPIRINHA-Dixon-TWIST-VIBE (CDT-VIBE) sequence couldobtain high-quality multiple arterial phases images and hepatic arterial dominant (HAD) images in short-time scanning.And it could not only detect small focal lesions which were difficult to find by other imaging examination,but also find the start enhanced difference between lesions which were relevant to lesions property and blood supplement.The CDT-VIBE has a high clinical value in diagnosis and treatment of SHCC.The research progresses of CDT-VIBE in diagnosis of SHCC was reviewed in this article.

Objective To evaluate the reliability and validity of hepatocellular carcinoma (HCC)using the liver imaging reporting and data system (LI-RADS).Methods By using the LI-RADS v2013.1,two radiologists evaluated 1 62 patients with cirrhosis or with a risk of HCC according to an inclusion criteria.The Kappa value was used to evaluate the consistency between two different diagnoses and was compared with pathological and follow-up results.The accuracy of the LI-RADS was assessed including sensitivi-ty,specificity,positive predictive value,negative predictive value,positive likelihood ratio,negative likelihood ratio and accuracy rating.Results In all 1 62 patients,there were HCCs in 97 patients including 7 patients belonging to the LR3,benign diseases in 50,and other kinds of malignancy in 1 5.The Kappa value was 0.882 (P =0.000)between two observers on LI-RADS grading. The sensitivity,specificity and accuracy rating of LI-RADS grading in diagnosing HCC was 100.00%,91.30%,and 97.06%,re-spectively.Conclusion The LI-RADS has high consistency and stability in evaluation and diagnosis of HCC by enhanced CT.LR3 di-agnosis should be cautious because of a susceptible development to HCC,which can be improved through the combination of clinic and laboratory examination.

Objective To investigate the effect of extract ofTangshen-HuazhuoRecipe(TSHZR) on the serum concentrations of transforming growth factorβ1(TGF-β1) and platelet derived growth factor(PDGF) in patients withⅣ stage of diabetic nephropathy(DN).Methods From June 2012 to December 2012, 98 patients ofⅣstage DN in our hospital outpatient were enrolled and randomly divided into treatment group(n=48) and control group(n=50) using random number table. All patients received conventional therapies of controlling blood sugar, lipid, blood pressure and anticoagulant therapy. On such basis, the control group was treated by irbesartan, 150 mg/d, and the treated group treated by TSHZR combined with irbesartan,150 mg/d, for 6 months. Serum TGF-β1 and PDGF were determined with ELISA before and after treatment,and urinary albumin excretion rate,HbA1c,serum creatinine,blood urea nitrogen and lipid profiles were examined as well. ResultsIn the treated group, the TGF-β1 was(172.5±31.3), (123.6±21.2)pg/ml, the PDGF was(860.9± 131.2), (500.6±130.2)pg/ml before the treatment and after the treatment, respectively. The TGF-β1 and PDGF after the treatment were significantly decreased than those before the treatment(P<0.01). After the treatment, TGF-β1 and PDGF in the treated group were statistically significant compared to the control group[TGF-β1 is(157.4±39.6)pg/ml, PDGF is(765.7±161.8)]pg/ml,P<0.01). After the treatment, the treatment group was superior to the control group in TG(1.72±0.25)mmol/L,(2.09±0.27)mmol/L,(P<0.01), TC(4.56± 0.64)mmol/L,(6.11±0.93)mmol/L, (P<0.01), HDL-C(1.56±0.50)mmol/L,(1.36±0.44)mmol/L, (P<0.01), LDL-C(2.46±1.08)mmol/L(3.32±0.87)mmol/L,(P<0.05)and UAER(100.73±204.24)μg/min, (226.24±396.38)μg/min, (P<0.01).Conclusion TSHZR can inhibit the progressive of IV stage of diabetic nephropathy by suppressing TGF-β1 and PDGF expression level.

Objective: To investigate the application of one stage otoptasty for congenital atresia of the external acoustic canal and malformations of the middle ear and the auricle. Method: patients with the ear malformations were given surgical reconstruction of one stage otoplasty. The auricle was reconstructed with the rib which was encapsuled with the superthin temporal flap. According to the malformations of the middle ear in patients, Ⅰ style tympanoplasty and Ⅲ style tympanoplasty were carried out respectively. All patients were performed myringoplasty with temporal fascia and reconstructed the external acoustic canal with full thickness skin-grafting. Result:A long term follow-up (4～6 years)demonstrated that 11 ears were survival of which 8 ears figuration were ideal. The hearing improvement was observed in all patients. Conclusion:one stage otoplasty is effective for treatment of the congenital malformations of the external and middle ear.

Objective To investigate the efficacy and safety of domestic exenatide injection versus imported exenatide injection in type 2 diabetic patients with inadequate glycemic control on monotherapy or combination therapy of metformin and insulin secretagogues. Methods A multicenter, randomized, parallel-controlled, and non-inferiority trial was carried out. A total of 240 subjects were randomized at a 1:1 ratio to add domestic exenatide injection (trial group) or imported exenatide injection (control group) on the background therapies. The primary endpoint of efficacy was HbA1C change from baseline to week 16. The secondary endpoints of efficacy were the proportion of HbA1C<7.0%, and the changes in fasting plasma glucose (FPG), 2 h plasma glucose after standard meal (2hPG), 7-point self monitoring of blood glucose (7P-SMBG), and body weight from baseline to week 16. Results Among subjects of per-protocol sets, adjusted mean HbA1C reduction was -1.07% in the trial group versus -1.06% in the control group after 16 weeks of treatment. The lower boundary of the two-sided 95% confidence intervals of the mean HbA1C reduction difference between the trial and control groups was -0.29%, which was more than -0.35%, suggesting that the predefined statistical criterion for non-inferiority was achieved. The proportions of subjects achieving HbA1C<7.0% at the end of the 16-week treatment were 56.19% and 54.08% in the trial and control groups, respectively (P>0.05). The changes in FPG, 2hPG, 7P-SMBG and body weight from baseline to week 16 were comparable between the two groups (all P>0.05). Moreover, the incidences of hypoglycemia and adverse events were similar between the two groups (both P>0.05). Conclusion In type 2 diabetic patients inadequately controlled by monotherapy or combination therapy of metformin and insulin secretagogues, the efficacy of cotreatment with domestic exenatide injection is not inferior to that of imported product ones, with a similar safety profile.

Objective: To explore the relationship between adolescents physical fitness and depressive symptoms, and to provide reference for the early prevention and intervention of depressive symptoms and improvement of physical fitness in Chinese adolescents. Methods: From September to December 2021, a total of 8 102 adolescents were selected by random cluster sampling method in Shanghai, Urumqi, Changsha and Kunming. The Center for Epidemiologic Studies Depression Scale(CES-D) was used to investigate the depressive symptoms, and completed grip strength, standing long jump, 50 m running, modified sitting forward flexion, 20 s repeated traverse, 30 s sit ups, 20 m round trip running (20 m SRT) test. χ 2 test, Goodman Kruskal Gamma and Logistic regression analysis were used to analyze the relationship between physical fitness index(PFI) and depressive symptoms. Results: The overall detection rate of depressive symptoms in adolescents with high level PFI was 23.4%, and the detection rate of low level adolescents was 26.3%, with a statistically significant difference ( χ 2=6.73, P =0.01). There was a significant positive correlation between PFI and depressive symptoms in the high school group ( G=0.09, P <0.05) and the boy group ( G=0.12, P < 0.05 ), and there was no significant association between PFI and depressive symptoms in the junior high school group and the girl group ( P >0.05). After adjusting for gender and age in the Logistic regression model, compared with those with high PFI, the risk of depressive symptoms in those with low PFI was 1.18 times (95% CI =1.05-1.33). Conclusion There is a correlation between physical fitness and depressive symptoms in adolescents. Adolescents with low PFI are at higher risk of developing depressive symptoms than those with high PFI.

Objective: This study aimed to examine the mediating effects of sleep quality in the association between beverages consumption and depressive symptoms in Chinese university students, and to provide a theoretical reference for preventing and reducing depression symptoms. Methods: This school-based cross-sectional survey was carried out among 4 624 university students from 2 universities in Anhui and Jiangxi provinces of China. The patient health questionnaire-9 items (PHQ-9) was used to assess depressive symptoms. The Pittsburgh sleep quality index（PSQI） was used to assess sleep quality, and a self-reported dietary frequency questionnaire was used to measure beverages consumption. The quantile regression model was used to association analysis, and the latent variable mediation model was used to analyze the mediation effect. Results: The positive rates of mild, moderate, moderate to severe and severe depression in 4 624 university students were 31.4%, 7.5%, 4.1% and 2.0%, respectively. There was a significant association between the beverages consumption score, the PSQI score, and the PHQ-9 score( P <0.01). The higher the quantile of the beverage consumption and PSQI score, the greater the regression coefficient ( β ), and a significant dose-response relationship was observed( P <0.01). In the latent variable mediation model of beverages consumption associated with depressive symptoms in Chinese university students, the mediating effect value of sleep quality was 0.12, and the ratio of mediating effect to total effect was 71.3%. Conclusion Our study demonstrates that poor sleep quality partially mediates the association between beverages consumption and depressive symptoms in Chinese university students.

Objective To investigate the prevalence and risk factors of diabetic retinopathy (DR) in a Beijing population during routine medical examinations. Methods This was a cross-sectional study during a routine health examination at the Tongren Hospital of Beijing,from March 2014 to February 2015. Fundus photography was conducted by experienced ophthalmologists.Medical history,height,weight,waist and hip circumference,and blood pressure were recorded.Routine laboratory examinations were performed. Logistic regression models were used to estimate the odds ratio (OR) and 95% confidence interval (CI) of diabetic retinopathy for each risk factor,adjusted for age and gender. Results The prevalence of DR was 7.0% among diabetic individuals.The multivariate analysis showed that disease durations[OR(95% CI),2.1 (1.564-2.752),P<0.001],fasting plasma glucose[1.2(1.093-1.273),P<0.001],body mass index[1.8(1.010-3.100),P=0.046],and triglyceride[0.794(0.638-0.987),P=0.038]were independently associated with DR. The prevalence of diabetes mellitus (DM) and DR significantly increased in populations aged>30 years. Conclusion Fundus photography (nonmydriatic) should be recommended as a routine screening method for people 30 years and elder to effectively prevent occurrence of visual impairment and blindness.
