OBJECTIVE:To study the current situation and developing trend of the antidiabetics used in Guangdong re?gion.METHODS:The antidiabetics used in44hospitals in Guangdong region during the period2000～2003were analysed concerning the kinds of drug,sum of money for consumption and frequency of drug use.RESULTS:The sum of money for consumption of antidiabetics increased year by year so did its proportion in sum of money for consumption of total drug.Among them,consumption of insulin increased very quickly and oral antidiabetics assumed a tendency of increase as well.CONCLUSI_ ON:The variety of insulin is stable and new oral antidiabetics is going into market occasionally in this region,but frequency of use is primary to sulfonylurea,biguanides and glycosidase-inhibitors.

Objective To study the effect of Shenqi Fuzheng injection (SQFZI,参芪扶正注射液) on renal function in patients after cardiac surgery and cardiopulmonary bypass (CPB).Methods Forty patients ready for receiving CPB and cardiac surgery were randomly assigned to two groups,20 being in each group. Patients in the SQFZI group were administered of 250 ml SQFZI intravenously before anesthesia,125 ml SQFZI before CPB in CPB mechanical equipment,and 250 ml SQFZI once a day after operation for 3 days. Equal volume balanced solution was received in control group.Creatinine (Cr) in blood and Cr,microalbumin (m-Alb),?_2-microglobulin (?_2-MG) and N-acetylglucosaminidase (NAG) in urine were measured and endogeneous creatinine clearance (CCr) was calculated in 40 patients at the time points of before anesthesia, at the end of operation,and 1,3 and 5 days after operation.Results Urinary levels of m-Alb,?_2-MG and NAG were increased significantly after CPB in both groups at different time points at the end of and after the operation (all P0.05).Conclusion CPB has a deteriorating effect on renal function,and the application of SQFZI in peri-operational period has a protective effect on renal function in patients who undergo CPB.

OBJECTIVETo determine the physiological role of D-bifunctional protein (DBP) in bile acid biosynthesis through investigating the effect of increasing activity of DBP on bile acid biosynthesis.

METHODSTwenty male Wistar rats were divided into two groups: diethylhexyl phthalate (DEHP) group (n = 10) and control group (n = 10). Serum triglyceride, total cholesterol, hepatic DBP activity, and fecal bile acids were assayed. The mRNA levels of hepatic peroxisome proliferator-activated receptor alpha (PPARalpha), DBP, and cholesterol 7alpha-hydroxylase (CYP7A1) were detected by RT-PCR.

RESULTSCompared with control group, serum triglyceride level was decreased significantly and PPARalphamRNA level was increased significantly in DEHP group (P < 0.01). Together with a sharp induction of DBP mRNA expression and DBP activity in DEHP group (P < 0.01), the levels of CYP7A1 mRNA and fecal bile acids were significantly increased by 1.9 times and 1.6 times respectively compared to control group (P < 0.01). There was a significantly positive correlation between DBP mRNA level or DBP activity and CYP7A1 mRNA level (r = 0.89, P < 0.01; r = 0.95, P < 0.01).

CONCLUSIONThe up-regulation of DBP mRNA and activity in liver can result in the increase in CYP7A1 mRNA expression and bile acid biosynthesis, suggesting that DBP may be involved in bile acid biosynthesis together with CYP7A1.

Objective To explore the three criteria of Ranson,CT severity index (CTSI) and the bedside index of severity in acute pancreatitis (BISAP) in assessment of severity and prognosis of acute pancreatitis.Methods A total of 503 diagnosed acute pancreatitis patients from January 2008 to April 2011 were studied retrospectively,including 356 mild acute pancreatitis (MAP) cases and 147 severe acute pancreatitis (SAP) cases.The differences of the three criteria of Rason,CTSI and BISAP in assessment of severity and prognosis of acute pancreatitis were compared with receiver operating characteristic (ROC) curve.The SAP group was divided into no organ failure group and organ failure group,and the predictive value of the three criteria in acute pancreatitis with organ failure was compared.Results There was significant differences between MAP group and SAP group with Rason,CTSI and BISAP score (x2 =236.88、126.24 and 101.27,P＜0.01).The sensitivity (97.3％) and AUC value (0.93) of Ranson criterion was highest.In no organ failure group and organ failure group of 147 SAP patients,there was significant difference between Ranson criterion and BISAP criterion (x2 =17.67 and 26.12,P＜0.01),both sensitivity were 100％,the specificity were 96％ and 85％ respectively,and the area under ROC curve (AUC) value of BISAP criterion (0.8) was the highest.In illness improved group and deteriorated group,the difference of score between Ranson criterion and BISAP criterion was significant (x2 ＝ 9.53 and 10.19,P＜0.05),and the AUC value of BISAP criterion (0.74) was the highest.Conclusions All three criteria can be used to determine the severity of acute pancreatitis.In predicting the risk of SAP with organ failure and prognosis,BISAP criterion is better than Ranson criterion.BISAP criterion is simple and easy to practice,which provides an important rule for evaluating the clinical condition of acute pancreatitis.

Objective To investigate the dynamic changes in achalasia patients by using high resolution manometry (HRM).Methods Twenty-four achalasia patients were enrolled for HRM examination and typing.The esophageal pressure of patients with different subtypes was analyzed.Chi-square test was used for count data analysis.Two independent samples t-test was used for measurement data.Results Among twenty-four achalasia patients,five patients were type Ⅰ and maledominated,18 patients were type Ⅱ and female was more than male,and only one male patient was type Ⅲ.The frequency of weight loss in type Ⅰ was higher than that of type Ⅱ (x2 =6.97,P=0.008).The frequency of chest pain and food reflux in type Ⅰ was higher than that of type Ⅱ (both P＞0.05).The average distance from the nares to the upper edge of the lower esophageal sphincter (LES) with the electrode successfully inserted into the stomach was (44.9±3.3) cm and to the lower edge of the LES was (48.0±3.2) cm.The average LES length was (3.1 ±0.7) cm,average intraabdominal LES length was (2.1 ±0.5) cm.The average LES resting pressure was (34.6 ± 13.8) mm Hg (1 mm Hg =0.133 kPa) and the integrated relaxation pressure (IRP) was (31.1 ± 12.0) mm Hg.Conclusion Esophageal manometry is the golden standard for achalasia diagnosis,and HRM may be a simple,direct viewing and accurate method for accessing esophageal motor function.

Objective To evaluate the incidence and significance of perineural invasion (PNI) in cervical cancer. Methods Retrospective chart review of patients with cervical cancer (stages Ⅰa2-Ⅱb) who underwent radical hysterectomy and pelvic lymphadenectomy from 2007 to 2012. To evaluate the incidence and significance of PNI in cervical and uterine tissues by microscopic examination. Results A total of 238 patients were included, 9.2% (22/238) patients with PNI in the cervical stroma. Patients with PNI were more likely to have adverse histopathologic features, including lymphoma vascular space invasion, parametrical invasion, depth of invasion, tomor size and lymph nodes metastases (all P<0.05). PNI were independent of age, international federation of gynecology and obstetrics (FIGO) stage, histopathology type and grade, and positive vaginal margin (all P>0.05). Patients with PNI had shorter disease-free and overall survival (P=0.002 and P=0.008, respectively). On multivariate analysis, risk factors for recurrence and death included parametrical invasion and depth of invasion (P<0.05). Similarly, risk factors for recurrence included lymph nodes metastases (P=0.024). However, PNI was not identified as an independent risk factor for either recurrence or death (P>0.05). Conclusions PNI exists in early cervical cancer. PNI is associated with tumor size, depth of invasion, parametrical invasion, lymphoma vascular space invasion and lymph nodes metastases. PNI represente a decreasing disease-free and overall survival in patients with early-stage cervical cancer, and is independently associated with multiple high-risk factors, which be informed management decisions regarding adjuvant therapy.

Mounting evidence has shown that side population (SP) cells are enriched for cancer stem cells (CSCs) responsible for cancer malignancy. In this study, SP technology was used to isolate a small subpopulation of SP cells in human gallbladder cancer cell line GBC-SD, and SP cells which had superior potential for proliferation in vitro and tumorigenesis in vivo were identified. Importantly, the abundance of GBC-SD SP cells was increased by a transforming growth factor-β (TGF-β)-induced epithelial-mesenchymal transition (EMT), and this effect was accompanied with a strong up-regulation of ABCG2 mRNA expression, and a decreased sensitivity to mitoxantrone. SP cells were restored upon the removal of TGF-β and the reversion of the cells to an epithelial phenotype, and smad3-specific siRNA reduced SP abundance in response to TGF-β. In conclusion, TGF-β-induced EMT by smad-dependent signaling pathway promotes cancer development and anti-cancer drug resistant phenotype by augmenting the abundance of GBC-SD SP cells, and a better understanding of mechanisms involved in TGF-β-induced EMT may provide a novel strategy for preventing cancer progression.
