Flexure Syndrome is a chronic disorder that seems to be caused by trapped gas at bends(flexures) in the colon.Symptoms include bloating,muscle spasms,and upper abdominal discomfort and its pathogenesis is an open question.Chinese medicine theory discriminates it as hypochondriac pain or stomachache due to dysfunction on qi,and processes valid treatment on the basis of an overall analysis on personal organs and meridian.

Objective To obtain reasonable treatment by urodynamic detection and analysis in patients with diabetic cystopathy (DCP) complicated with benign prostatic hyperplasia (BPH).Methods Sixty patients with DCP complicated with BPH were selected,among the total 32 patients (duration of diabetes ＞ 12 years,blood glucose control was not ideal) were recognized as experimental group,and 28 patients (duration of diabetes ≤ 8 years,blood glucose control was stable) were recognized as control group.Using the Laborie UDS-120XLT urodynamic detection instrument,the urodynamic was detected and the international prostate symptom score (IPSS) was evaluate,and the results were compared between the 2 groups.Results There was no statistical difference in residual urine volume between experimental group and control group [(146 ±71) ml vs.(160 ±64) ml,P ＞0.05].The maximum urinary flow-rate in experimental group was significantly lower than that in control group [(5.4 ± 2.0) ml/s vs.(8.0 ± 3.2) ml/s],the symptom total score of IPSS was significantly higher than that in control group [(25.8 ± 4.1) scores vs.(22.6 ±5.0) scores],there were statistical differences (P ＜0.01).The maximum bladder capacity,compliance,incipient micturition desire volume in experimental group were significantly lower than those in control group,there were statistical differences (P ＜ 0.01).Conclusions The influence of DCP on the function of the bladder in BPH patients is significant.Urodynamic detection can provide objective basis for the selection of therapeutic methods,suitable to be operated and forecast the postoperative effect.It has an important reference value in DCP complicated with BPH patients.

Objective: To investigate the clinical characteristics and the effectiveness of surgical treatment of adrenal cysts. Methods: The clinical data of adrenal cysts in Affiliated Zhangye people′s Hospital, Hexi College from May 2005 to July 2018 were retrospectively analyzed, including clinical manifestations, diagnosis, surgical methods, postoperative pathological results and follow-up process. Seventeen patients with adrenal cysts were identified including 10 males and 7 females. The median age was 45.6 ranging from 30 to 75. There were 12 left lesions and 5 right lesions. Only 4 patients (23.5%) had clinical symptoms, including low back pain, abdominal pain and dizziness caused by hypertension. Ultrasound, CT and MRI were the main imaging methods for preoperative diagnosis. Results: All patients underwent surgical treatment. Laparoscopic surgery was adapted in 14 cases. The average operation time was (70.2 ± 18.5) min and the average bleeding was (47.0 ± 12.1) ml. For open surgery in 3 cases, the average operation time was (103.5 ± 25.0) min and the average bleeding was (85.6 ± 20.5) ml. Postoperative pathological results showed endothelial cysts in 11 cases, epithelial cysts in 3 cases and pseudocysts in 3 cases. No recurrence of cysts or hypoadrenalism occurred in 3-75 months′ follow-up. Conclusions Adrenal cysts are relatively rare and generally benign lesions. Imaging examination, especially abdominal enhanced CT is essential for diagnosis. Laparoscopic surgery is a safe and effective method for the treatment of adrenal cysts.

Objective To evaluate the effect and mechanism of tribulus terrestris in kidney calcium oxalate stone in rats.Methods Sisty healthy male Wistar rats were divided into control group,model group,low-dose prevention group,high-dose prevention group,low-dose treatment group,high-dose treatment group by random number table method,each group of 10 rats.The control group was had free access to water,the model group was given 1％ ethylene glycol had free access to water,and the low-dose prevention group was given 1％ ethylene glycol had free access to water while was added in Tribulus terrestris extract 250 mg/(kg · d) treated by gavage,the high-dose prevention group was given 1％ ethylene glycol had free access to water while was added in Tribulus terrestris extract 500 mg/(kg · d) treated by gavage.The low-dose treatment group received 1％ ethylene glycol had free access to water while was added in tribulus terrestris extract 250 mg/(kg · d) treated by gavage on the 15th day.The high-dose treatment group received 1％ ethylene glycol had free access to water while was added in tribulus terrestris extract 500 mg/(kg · d) treated by gavage on the 15th day.At the end of the experiment on the 28th day,the body weight,blood urea nitrogen,creatinine,P,Ca2+,Mg2+ content,24 h urine volume,24 h urine Ca2+,Mg2 +,P,oxalic acid secretion,renal tissue homogenate detection of superoxide dismutase (SOD),glutathione peroxidase (GPX),malondialdehyde content of each group were detected.The crystal deposition and pathological changes of calcium oxalate were observed under the microscope.Measurement data were expressed as mean ± standard deviation (Mean ± SD),multiple comparisons between groups were performed using LSD-t test,and comparison between groups was performed by one-way anova analysis of variance.Results Compared with the control group,the rats in the model group had blood urea nitrogen (28.93 ±3.37) mmol/L,creatinine (162.31 ± 34.08) μmol/L,24 h uric acid (132.67 ± 27.96) μmol,Ca2+ (18.24 ± 1.94) μmol/24 h,the content of malondialdehyde (191.04 ± 20.56) nmol/mgprot in kidney homogenate was significantly increased,blood Ca2+ (2.01 ±0.28) mmol/L,renal GPX (479.82 ± 136.97) μmol/gprot,SOD(1.54 ±0.21) U/mgprot decreased significantly,these differences were statistically significant (P ＜ 0.05).Renal histopathology showed low-dose and high-dose prevention and treatment groups kidney calcium oxalate crystals and kidney damage were less than the model group.Conclusion The extract of Tribulus terrestris has a beneficial effect against calcium oxalate urinary stone formation induced by ethylene glycol.

Objective:To evaluate the expression of Vimentin and its relationship with clinical pathological data and prognosis in patients with metastatic renal cell carcinoma (mRCC).Methods:A total of 269 mRCC patients, from June 2007 to June 2017, treated with tyrosine kinase inhibitors (TKI) in Zhongshan Hospital, Fudan University were included in the study. Vimentin was assessed by immunohistochemistry on continuous paraffin embedded slides. To analyzed the relationship between Vimentin expression and clinicopathological data and prognosis. Measurement data were expressed as mean±standard deviation ( Mean± SD). The relationship between Vimentin expression and clinicopathological data of mRCC patients was determined by Chi-square test. Survival analysis used Kaplan-Meier survival curve, Log-rank test to judge the relationship between Vimentin expression and patient′s overall survival, and COX regression analysis was used for univariate and multivariate analysis. Results:Vimentin was expressed in cytoplasm of tumor cells. Vimentin expression in mRCC patients′ tissues was positively correlated with tumor Fuhrman grade ( P=0.002), and negatively correlated with prognostic overall survival ( P=0.001). Multivariate regression analysis showed that Vimentin expression was an independent risk factor for overall survival in patients with mRCC ( P=0.006). Conclusions:Vimentin expression can be used as a prognostic indicator of mRCC. It is expected that Vimentin can provide prediction for the prognosis of mRCC patients treated with TKI.
