A novel method for analysis of three active components curcumin, demethoxycurcumin and bisdemethoxycurcumin in Curcuma longa L. was developed by HPLC coupled with electrochemical detection. Three curcuminoids were well separated on a C18 column and detected with high sensitivity. A mobile phase containing acetonitrile and 10 mM Na2HPO4-H3PO4 (pH 5.0) (50:50, v/v) was used. Good linearity was obtained in the range of 0.208-41.6, 0.197-39.4, and 0.227-114μM for curcumin, demethoxycurcumin and bisdemethoxycurcumin respectively. The limit of detection reached up to 10 ? 8 M, which was lower than that by UV detection. The relative standard deviations (RSDs) ranged from 1.06%to 1.88%for intra-day precision and from 4.30%to 5.79%for inter-day precision, respectively. The proposed method has been applied in real herb sample and recoveries ranging from 86.3%to 111%were obtained.

Objective To assess the effectiveness of a novel mobile health patient management system involving doctors, nurses, and patients ( TRIO mode) on glycemic control and self-monitoring of blood glucose (SMBG) compliance among the type 2 diabetes mellitus ( T2DM) patients using basal insulin standardization treatment in China. Methods From April 2014 to April 2015, 416 hospitals in 110 cities of 30 provinces, municipalities, and autonomous regions across China were selected to participate in the program. A Online-to-Offline ( O2O) integrated mobile health patients management system with mobile terminals for the doctors, nurses, and patients was applied in the program for patient education, follow-up, and data collection. For all the newly recruited patients, the baseline information was collected and a first-day patient education program were provided by a designated nurse. In the 12-week follow-up period, data of basal insulin doses and fasting plasma glucose ( FPG) values were collected from the patients by text messages or tracking phone call by the nurse. The patients also received timely standardized patients health education and glycemic control guidance by participating in thepatient education forum anddoctors' hotline in order to help them achieve the glycemic control goals. Results A total of 102 524 patients using basal insulin treatment were eligible and enrolled in the program. 64 420 patients completed the 12 weeks follow-up and provided at least one FPG value at all five follow-ups. In total, 62. 6% (40 334 / 64 420) of the patients reached the FPG control target(FPG≤7. 0 mmol/ L) at the end of follow-up period. The weekly average FPG for patients with complete SMBG data decreased from 10. 58 mmol/ L to 6. 91 mmol/ L while the FPG control rates increased from 13. 4% to 69. 2% . The weekly average FPG for the patients provided incomplete SMBG data decreased from 10. 54 mmol/ L to 7. 13 mmol/ L while the FPG control rates increased from 13. 6% to 62. 2% . The FPG control rates for the patients provided complete SMBG were 1. 74 times higher than those patients provided incomplete SMBG. Based on a GEE model, the average decline of the FPG and the increase of the FPG control rates were significantly better for patients who provided complete SMBG as compared to the patients with incomplete SMBG data. The results of the multivariate logistic regression analysis showed that factors such as receiving the first-day education, participating in the follow-up patient education forum, and the doctors' hotline were significantly associated with the improvement of the SMBG compliance, the treatment adherence, and the FPG control rates. The SMBG compliance and the treatment adherence for patients who completed first-day education were 1. 68 times and 1. 22 times higher, respectively. For the patients who participated in follow-up education activities, their SMBG compliance and treatment adherence were 3. 17 times and 3. 36 times higher, respectively. Conclusion The innovativeTRIOmobile health patient management mode was feasible and effective for better managing the type 2 diabetes patients initiated on basal insulin treatment in China. Active participation in the first-day education program and the follow-up patient education activities can effectively improve the SMBG compliance and the treatment adherence, and therefore play an important role in helping patient achieving FPG control in a faster manner.

Objective To summarize and analyze the perioperative complications of irreversible electroporation (IRE) ablation in treating tumors at different locations and to discuss their managements. Methods A total of 200 patients with tumors, including pancreatic tumor (n=71), liver tumor (n=64) and other tumors (n =65), were enrolled in this study. All patients received IRE ablation treatment. The perioperative complications were recorded and the data were statistically analyzed. The causes of severe complications and the treatment of complications were discussed. Results None of the patients died during the course of IRE ablation procedure. Severe postoperative complications occurred in the patients with pancreatic tumor or liver tumor, including duodenal artery bleeding in 3 patients with pancreatic tumor, which occurred at 10 days, 11 days and 15 days after IRE ablation respectively, and gastrointestinal bleeding (n =1) and biliary septic shock (n=1) in 2 patients with liver tumor, which occurred at 9 days after IRE ablation, the clinical symptoms were controlled after interventional embolization and/or vascular ligation together with anti-infective therapy. All minor complications were relieved after symptomatic treatment within 14 days. Conclusion IRE ablation has less systemic inflammatory response, and both the intraoperative and postoperative adverse reactions can be easily controlled, besides, IRE ablation has higher clinical safety. Although IRE ablation procedure may damage the internal or peripheral vessels of the pancreatic tumor, this severe complications can be effectively avoided if proper measures are adopted based on the causes of complications.

BACKGROUNDSelf-monitoring of blood glucose (SMBG) by individuals with type 2 diabetes (T2D) is crucial for long-term health, yet numerous cultural, economic and health factors can reduce SMBG. Most studies on SMBG adherence have come out of the US and Europe, and their relevance to Asia is unclear. The aims of the present study were to assess the current state of SMBG in China and analyze demographic and diabetes-related characteristics that may influence it.
METHODSIn this multi-center, cross-sectional study, 5 953 individuals with T2D from 50 medical centers in 29 provinces across China filled out a standardized questionnaire that requested information on demographic characteristics, education level, occupation, income, lifestyle risk factors, duration of diabetes, chronic complications, and frequency of SMBG. Respondents were also asked whether their glycosylated hemoglobin (HbA1c) had been checked in the past 6 months. The most recent values for fasting plasma glucose, 2-hour postprandial blood glucose and HbA1c were recovered from medical records.
RESULTSOnly 1 130 respondents (18.98%) performed SMBG with the recommended frequency, while 4 823 (81.02%) did not. In fact, nearly 2 105 (35.36%) reported never performing SMBG. In the subset of 3 661 individuals on insulin therapy, only 266 (7.27%) performed SMBG at least once a day, while 1 210 (33.05%) never performed it. In contrast, 895 of 2 292 individuals (39.05%) on diet/exercise therapy or oral hypoglycemic therapy never performed it. Multivariate Logistic regression identified several factors associated with SMBG adherence: female gender, higher education level, higher income, longer T2D duration and education about SMBG.
CONCLUSIONSSMBG adherence in our Chinese population with T2D was less frequent than that in developed countries. Several factors influence SMBG adherence: gender, education level, income, T2D duration, therapy regimen and exposure to education about SMBG.

BACKGROUNDInsulin injection therapy is one of the most effective treatments for type 2 diabetes mellitus (T2DM). Many people with T2DM in western countries resist starting insulin therapy; whether the same is true in China is unknown. This survey-based study assessed acceptance and rejection of insulin therapy among individuals with T2DM in China and self-reported reasons for these therapy choices. It also examined what methods may be useful for increasing the rate of insulin acceptance.
METHODSA multi-center, cross-sectional survey was conducted between April and July 2010 to a convenience sample of inpatients and outpatients at 50 medical centers across 29 administrative divisions in China. Data were collected on sociodemographic and T2DM characteristics, therapy regime, and attitudes toward insulin therapy.
RESULTSA total of 6 043 patients were surveyed, and 5 961 complete questionnaires (98.6%) were used in the analysis. Just over half the respondents (3 460, 58.0%) reported negative attitudes to insulin therapy, including 2 508 of the 4 469 patients (56.1%) whose physicians had recommended it to them. Of the patients counseled to use insulin, 800 (17.9%) were unwilling to start therapy and cited the following reasons: inconvenience (64.3%); concerns over addiction (24.6%); pain (14.3%); side effects (14.1%); and high cost (13.6%). Logistic regression suggested that respondents would be more willing to undertake insulin therapy if they had received diabetes education, had positive attitudes to the treatment, had higher glycosylated hemoglobin level, or had suffered diabetes for a longer period or with more complications.
CONCLUSIONSPatients with T2DM in China are often resistant to insulin therapy if they have been diagnosed with the disease for a relatively short time or if the disease has been relatively mild. Educating patients on the benefits of insulin therapy, not only at the initial diagnosis with T2DM but also when insulin therapy becomes necessary, will likely increase their willingness to undertake it.

OBJECTIVE:To analyze the effects of mangiferin (MGF)on glucose and lipid metabolism in insulin resistance (IR)HepG2 cells,and to explore the potential mechanism. METHODS :Using human hepatoma HepG 2 cells as research objects , 1 mmol/L palmitic acid and 2 mmol/L oleic acid were used to establish the IR-HepG 2 cell model. Using metformin hydrochloride as positive control ,the effects of low-concentration ,medium-concentration and high-concentration MGF (125,250,500 μmol/L)on the corrected glucose consumption ,the contents of triglyceride (TG)and total cholesterol (TC)in IR-HepG 2 cells were detected. The mRNA expression of APN ,AdipoR2,APPL1,AMPK in the upstream of AMPK signaling pathway and IRS- 1,Akt and GLUT4 in the downstream insulin signaling pathway were detected by RT-PCR. The phosphorylation level of AMPK protein was detected by Western blot assay. RESULTS :Compared with control group ,corrected glucose consumption ,mRNA expression of APN,AdipoR2,APPL1,AMPK,IRS-1 and GLUT 4,as well as the phosphorylation level of AMPK protein were decreased significantly in model group ,while the contents of TG and TC were increased significantly (P<0.05 or P<0.01). Compared with model group , corrected glucose consumption , mRNA expression of APN (except for MGF medium-concentration and high-concentration groups ),AdipoR2,APPL1,AMPK(except for MGF medium-concentration and high-concentration groups ), IRS-1(except for MGF medium-concentration and high-concentration groups ),Akt(except for positive control group ),GLUT4 (except for MGF high-concentration group )were increased significantly in administration groups ,while the contents of TG and TC were decreased significantly (P<0.05 or P<0.01). CONCLUSIONS :Mangiferin may activate APN ,which is the upstream target of pathway ,and then regulate AMPK signaling pathway ,so as to promote glucose uptake of IR-HepG 2 cells,reduce TG and TC contents,and improve IR and abnormal glucose and lipid metabolism.
