Objective To understand the effect of anti-cysticercus therapy for patients with cerebral cysticercosis and the changes of cysticercus on CT image after treatment. Methods The patients with cerebral cysticercosis were classified by the presentation of their brain CT image before treatment, then the effect of anti-cysticercus therapy on them after treatment was analyzed and the presentations of their brain CT images between before and after treatment were compared. Results There were different changes on CT image of cysticercus in brain tissues after anti-cysticercus therapy for different types of patients with cerebral cysticercosis. Type Ⅰ: the focus was absorbed completely after treatment in the majority of patients and calcificated in the minority. Almost all the patients were cured clinically after anticysticercus therapy. Type Ⅱ: the focus was absorbed completely in the minority, and one to two or more calcification dots were observed in the majority of patients. Anti-cysticercus therapy was effective. Type Ⅲ and Ⅳ: the absorption of focus was not very good and the effect of anti-cysticercus therapy was lower relatively. Conclusion The changes of CT image such as absorption, calcification, has important significance in forecasting prognosis and instructing clinical usage.

Objective To evaluate the diagnostic performances of seven estimation formulas for glomerular filtration rate (GFR) in pre-operative patients with renal cell carcinoma.Methods A total of 386 pre-operative patients with renal cell carcinoma in the first affiliated hospital of Chongqing medical university from January 2012 to October 2014 were selected.All the patients' GFRs were measured by the renal dynamic imagingwith 99mTc-DTPA as reference (rGFR) and the seven GFR estimation equations (eGFR) were compared with the rGFR respectively.Their correlations and consistencies were observed with spearman correlation analysis and Bland and Altman analysis.The diagnostic sensitivity,specificity and likelihood ratios were calculated and the eGFR accuracies were assessed with receiver operator curve (ROC) analysis.Results The correlations between the rGFR and eGFRs were significantly (P＜0.001).In addition,CKD-EPI-Asian Crea and Ruijin formula were more accurate than others in different stages with larger ROC area in diagnosing renal cell carcinoma.Conclusion There were significant correlations between the eGFRs and rGFR,but some deviations existed.CKD-EPI-Asian Crea and Ruijin formula were more suitable for assessment of eGFR of pre-operative patients with renal cell carcinoma.However,both of these equations had a few limitations.

Recently, the Th17 cells and IL-17 have been shown to play a critical role in the immune-mediated liver injury in hepatitis B, while their functions in acute liver failure have not been well elucidated yet. In this study, we primarily investigated the role of IL-17 in the development of mouse hepatitis virus strain 3 (MHV-3)-induced acute liver failure. IL-17 mRNA levels in liver tissue were quantified by using quantitative real-time polymerase chain reaction, and cytokine IL-17 levels in liver tissue and serum were determined by using ELISA in MHV-3-induced murine fulminant hepatitis model. The IL-17 expression levels on CD4(+)T and CD8(+)T cells were determined by using flow cytometry. The correlation between IL-17 level and liver injury was studied. Th17 associated cytokines were also investigated by intracellular staining. Our results showed that the IL-17 expression was significantly elevated in the liver and serum of BALB/cJ mice infected with MHV-3. Moreover, a time course study showed that the percentage of both IL-17-producing CD4(+)T cells and IL-17-producing CD8(+)T cells was increased remarkably in the liver starting from 48 h and peaked at 72 h post-infection. There was a close correlation between hepatic or serum IL-17 concentration and the severity of liver injury defined by ALT level, respectively. Th17 associated cytokines, IL-6, IL-21 and IL-22, were also increased significantly at 72 h post-infection. It was concluded that IL-17 may contribute to the pathogenesis of MHV-3-induced acute liver failure.

Objective To investigate the relationship between lymph nodes count after selective neck lymph node dissection and the prognosis of patients with pathologically lymph node-negative (pN0) hypopharyngeal squamous cell carcinoma (HPSCC). Methods The clinical data of 96 patients with pN0 HPSCC undergoing selective neck dissection (bilateralⅡ-Ⅳregion) from October 1995 to October 2012 in Shanxi Provincial Cancer Hospital were analyzed retrospectively. The optimal lymph nodes count cutoff values were determined by using the X-tile program in different prognostic groups, and the univariate and multivariate survival analysis in different groups were analyzed by using SPSS 19.0 software. Results A total of 2116 lymph nodes were detected in this cohort, with a median number of 22 (3-52). Except for the tumor site (P= 0.011), there were no statistical differences in lymph nodes count of patients with different age, gender, history of smoking or drinking, T stage, and differentiation degree (all P> 0.05). Applying 9 and 23 nodes as the cutoff values determined by using X-tile program, all patients could be divided into the high-risk (13 cases, lymph nodes count 3-9), the middle-risk (37 cases, lymph nodes count 10-22) and the low-risk (46 cases, lymph nodes count 23-52) groups. And the 5-year overall survival (OS) rate was 23.1 ％, 55.9％and 86.0％in the high, middle, low risk groups respectively (χ2= 21.73, P< 0.001). Multiple-factor analysis showed that lymph nodes count, T stage and degree of tumor differentiation were independent prognostic factors in patients with pN0 HPSCC (all P< 0.05). Further analysis showed that when the cutoff value of lymph nodes count was 9, the patients could be divided into two groups with significantly differentprognosis. The 5-year OS rate was 23.1％ in the high-risk group and 73.2 ％ in the low-risk group, and the difference was statistically significant (χ2 = 17.87, P< 0.001). Conclusions Lymph nodes count after selective neck lymph node dissection can be used to predict the prognosis of patients with pN 0 HPSCC. It is likely that 9 is the minimum number of lymph nodes in pN0 HPSCC patients.

Objective:To observe different efficacies of low-frequency electroacupuncture (EA) on pancreatic endocrine system in male and female patients with simple obesity due to spleen deficiency-related dampness.Methods:A total of 80 simple obesity patients were assigned to a male group (n=37) and a female group (n=43). Both groups received a 30-minute low-frequency EA at Yinlingquan (SP 9), Sanyinjiao (SP 6), Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Guanyuan (CV 4). The treatment was done once a day, and 10 times made up a course of treatment. Patients in both groups were treated for 2 courses. Then the changes in body mass index (BMI), serum insulin, insulin antibodies and leptin level in the two groups were observed and analyzed.Results:After treatment, the BMI, serum insulin, insulin antibodies and leptin levels were significantly reduced in both groups (P<0.01 orP<0.05); the BMI and serum insulin concentration were more significantly reduced in the male group than those in the female group (bothP<0.01); and the leptin level was more significantly reduced in the female group than that in the male group (P<0.01).Conclusion: EA can significantly regulate BMI and pancreatic endocrine system in both men and women with simple obesity; however, there is a gender difference: better effect for men in reducing BMI and serum insulin and better effect for women in reducing serum leptin level.
