Objective To study the role of autophagy in the curcumin (Cur) enhancing the chemosensitivity of the colorectal cancer LoVo cells to irinotecan (CPT-11). Methods The LoVo cells were separated into 4 groups:the control group,the Cur group,the CPT-11 group and the Mix group.Western blot assay was applied to determine the expression of autophagy-related protein LC3-Ⅱ and P62. LC3-Ⅱ was detected by immunofluorescence method. Transmission electron microscopy was used to detect the autophagosome. CCK-8 assay was applied to detect the cell growth inhibitory rate of LoVo cells ,which were pre-treated with autophagy inhibitor 3-MA before 24-h treatment of Cur and/or CPT-11. Western blot assay was applied to detect the expression of LC3- Ⅱ and P62. Results The mixed treatment significantly increased the expression of LC3-Ⅱwhile decreased P62 expression,compared with the Cur and CPT-11 treatments. The autophagosomes in cells of Mix group were significantly more than those in cells of the Cur and Cpt group. Pre-treatment of 3-MA significantly reduced cell growth rate in the Cur group,the Cpt group and the Mix group. Pre-treatment of 3-MA significantly decreased the expression of LC3-Ⅱ,while increased P62 expression,compared with the Mix group. Conclution Combinations of curcumin and CPT-11 could enhance the chemosensitivity of LoVo cells to CPT-11,which might be related to the activation of autophagy.

Objective To investigate the effects of short-term continuous subcutaneous insulin infusion (CSII) on plasma visceral adipose tissue-derived serine protease inhibitor ( vaspin ) levels in patients with recentonset type 2 diabetes mellitus, and to study the association between insulin sensitivity and vaspin levels.Methods Thirty patients with recent-onset type 2 diabetes mellitus were treated with CSII for 2 weeks.Euglycemic-hyperinsulinemic clamps (EHC) were performed to evaluate the insulin sensitivity in type 2 diabetes group. Plasma vaspin levels were measured by an ELISA kit. The association between plasma vaspin levels and metabolic parameters were analyzed. Results Fasting plasma vaspin levels were higher in type 2 diabetes than in impaired glucose regulation and normal glucose tolerance groups [( 1.83±0.55 vs 0. 43±0.21 and 0.56±0.26) ng/ml,P＜0.05]. With CSII,vaspin levels [( 1.19 ±0.57 vs 1.83 ±0.55 ) ng/ml, P＜0.05] and homeostasis model assessment for insulin resistance [HOMA-IR ,2.30 ( 1.09-7.2 ) vs 4.28 ( 1.7-6.47 ), P＜0.05] were significantly decreased,accompanied with an increase in glucose metabolic rate [(5. 10±0.51 vs 2.99±0.42 )mg·kg-1·min-1 ,P＜0.05] in type 2 diabetes group. Changes in circulating vaspin concentrations were correlated positively with changes in HOMA-IR. Conclusion In type 2 diabetic patients,elevated plasma vaspin levels are significantly decreased after CSII treatment. Vaspin may play a role in improving insulin sensitivity of diabetic humans.

Objective To study the surgical diagnosis and treatment of renal tuberculosis(TB). Methods The clinical data of 42 cases with renal TB were analyzed retrospectively and the experiences of clinical diagnostic and treatment were summarized. Results Cystic irritation symptoms(78.6% ,33/42)and gross hematuria(64. 3%,27/42)were the most common symptoms in these patients. Abnormal urine were found in 83.3 % cases. Acid-fast stains on urinary sediment were positive in 28.6%(12/42)of cases. The diagnostic accuracy of B-ultrasonicgraphy,IVU,retrograde pyelography and CT examination in these patients were 19.0%(8/42),33.3% (14/42),26.2%(11/42)and 71.4%(30/42)respectively. Among all cases enrolled in the study,6 patients received antiphthisic medicine treatment,3 of them were cured and the other 3 accepted nephrectomy and partial ureterectomy after 6-12 months because of severe renal function impairment 36 cases received surgical treatment. In the 39 cases treated with operation,all of them were proved to carry renal tuberculosis by the postoperative pathological examinations. Conclusions The medical history,urine analysis,image examination should be considered synthetically in the clinical diagnosis of renal tuberculosis. The patients should be followed up closely during antiphthisic treatment period. Seriously damaged or nonfunctioning kidney should be removed promptly.

Objective To investigate the prevalence and risk factors of adult chronic kidney disease (CKD) in the Xishuangbanna district of Yunnan province with a big population of minorities. Methods Residents aged 20 years and older in the area of Xishuangbannan were randomly selected by using a stratified, multi-stage sampling method. All the residents were tested for morning spot urine of albumin tO creatinine ratio (ACR) (abnormal≥ 30 mg/g); morning spot urine dipstick of hematufia (abnormal 1+ or greater) was confirmed by urine microscopy (abnormal ＞ 3 red blood cells/HP); and modified simplified MDRD equation for Chinese adult was applied to characteristics, health characteristics (e.g. hyperglycemia, hyperlipidemia and hypertension) and indicators of kidney damage were also examined. Results Eligible data of 5566 subjects were included in the study. The prevalence of albuminuria was 8.06%, hematuria was 4.01% and reduced eGFR was 2.89%. Apart from the repetition among microalbuminuria, hematuria and reduced eGFR, approximately 12.53% subjects had at least one indicator of kidney damage. The prevalence of CKD in stratified subgroups with age, gender, nations and CKD risk factors was coincidence with the Logistic regression results. Age increase, hypertension, byperlipidemia and fasting plasma glucose increase were independently associated with albuminuria; age increase, hypertension were independently associated with reduced renal function; age increase was independently associated with hematouria. Conclusions The prevalence of adult chronic kidney disease is 12.53% in the Xishuangbanna district of Yunnan province. Independent risk factors associated with kidney damage are age, hyperglycemia, hyperlipidemia and hypertension.
