Objective To assess the effects of very-low-carbohydrate diet (VLCD) on body function and body composition in obese or overweight subjects.Methods Thirty five overweight or obese subjects were enrolled in the study,including 10 males and 25 females with a mean age of (43 ± 10) years.All subjects received VLCD intervention and 30 min moderate-intensity exercise daily for 3 months.The height,weight,blood pressure,heart rate,blood lipids and body composition were measured before and 1,3 months after intervention.ANOVA or nonparametric test was used for statistical analysis.Results After 3-month intervention,compared to baseline,the average body weight was decreased by 17.2 and 5.9 kg,waist circumference was decreased by 15.1 and 4.5 cm,BMI index decreased by 4.3 and 3.4 kg/cm2,waist to hip ratio was decreased by 0.1 and 0.1,for males and females,respectively (F =11.65 and 5.28,8.36 and 3.73,9.28 and 12.06,3.32 and 19.43,all P ＜ 0.05).Compared with the baseline,the systolic pressure was decreased by 12.2 and 9.2 mmHg(1 mmHg =0.133 kPa),triglycerides were decreased by 0.25 and 0.42 mmol/L,fasting blood glucose was decreased by 0.13 and 0.43 mmol/L after 1 month and 3 months of intervention,respectively.The proportion of patients with fatty liver was decreased from 69％ (24/35) at baseline to 49％ (17/35) at 1 month after intervention and further to 6％ (2/32) at 3 months after intervention (x2 =27.52,P ＜ 0.05).Conclusion The results indicate that VLCD can effectively control the body weight,and significantly improve the state of body function disorder.

To investigate the association between Helicobacter pylori ( Hp ) infection and type 2 diabetes.Total 4 129 health check up subjects aged (49.1 ±11.3) years (18-92 years), including 2 649 males and 1 480 females were enrolled in this cross-section study.Hp infection was confirmed by 13 C-urea breath test;type 2 diabetes mellitus was diagnosed according to WHO criteria (1999).Single factor analysis and multiple regression analysis were used to evaluate the association between Hp affection and the prevalence of type 2 diabetes.Hp infection rate in diabetic group was significantly higher than that in non-diabetic group (45.6%vs.39.0%, P<0.05).Hp infection rate in subjects with newly diagnosed diabetes was highest than those with previously diagnosed diabetes and non-diabetic subjects ( P<0.05).The glycosylated hemoglobin level in Hp infection group was higher than that in non infection group [ ( 5.88 ±0.64 )% vs.( 5.62 ± 0.88)%, P<0.05];the fasting plasma glucose and postprandial blood glucose levels in Hp infection group were also higher than those in non-infection group ( P<0.05 ).Logistic regression analysis showed that Hp infection was one of the independent risk factors of type 2 diabetes (OR=2.002, 95%CI:1.564-2.563, P<0.05).The study indicates that Hp infection is closely associated with type 2 diabetes mellitus.

Objective To explore the short- term efficacy of argon- helium knife cryotherapy followed by chemotherapy in treating advanced non- small cell lung cancer (NSCLC) and to investigate its effect on the long- term survival. Methods During the period from March 2005 to March 2008, a total of 61 patients withⅢb or Ⅳ stage NSCLC received argon- helium knife cryotherapy followed by chemotherapy (study group), and other 52 patients with Ⅲb or Ⅳ stage NSCLC were treated with chemotherapy only (control group). The clinical data were retrospectively analyzed. The pain was evaluated by numeric rating scale (NRS) and the quality of life (QOL) was assessed by functional assessment of cancer therapy- general (FACT- G) scale. The clinical effect was evaluated according to RECIST criteria for solid tumor, and the patient’s survival time was recorded. Results (1) Twenty- six patients had local pain before the treatment, and the pain was relieved in different degrees after cryotherapy. The QOL, including all respects of FACT - G, was significantly improved after cryotherapy in all 61 patients. (2) The remission rate of the study group and the control group was 34.4% and 15.4% respectively, the difference between the two groups was statistically significant (P <0.05). (3) The median survival time of the study group and the control group was 12.9 months and 9.5 months respectively, and the one- year survival rate of the study group and the control group was 53.6% and 35.4% respectively. The differences between the two groups were statistically significant (P < 0.01). Conclusion Argon- helium knife cryotherapy is a safe and effective local treatment for advanced NSCLC, which can quickly reduce the tumor load, relieve the pain and improve patient’s quality of life. Cryotherapy with subsequent chemotherapy is superior to simple chemotherapy in improving the patient’s survival rate.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion for adjuvant treatment of depression in Parkinson disease and explore its mechanism. Methods: A total of 80 patients with Parkinson disease coupled with depression were randomized into an observation group and a control group, with 40 cases in each group. The control group was treated with levodopa and benserazide hydrochloride tablets and paroxetine tablets, while the observation group was treated with heat-sensitive moxibustion on the basis of the medications in the control group. The treatment course was 2 months. The Hamilton depression scale-17 (HAMD-17), unified Parkinson's disease rating scale (UPDRS) and Parkinson's disease quality of life questionnaire-39 (PDQ-39) were scored before and after the treatment, and the efficacy was evaluated after treatment. Levels of patients' serum dopamine (DA), 5-hydroxytryptamine (5-HT), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before and after the treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). The HAMD-17 scores in the two groups decreased significantly after treatment (both P<0.05), and the score in the observation group was obviously lower than that in the control group (P<0.05). The component scores and total scores of UPDRS in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (all P<0.05). The score of PDQ-39 in the observation group decreased significantly (P<0.05), and was lower than that in the control group (P<0.05). After treatment, the serum DA and 5-HT levels in the observation group increased significantly (both P<0.05) and the TNF-α and IL-6 levels decreased significantly (both P<0.05), which were statistically different from those in the control group (all P<0.05). Conclusion: Heat-sensitive moxibustion has certain auxiliary effect in treating depression in Parkinson disease, significantly improving clinical symptoms and the quality of life, which may be related to the up-regulation of DA and 5-HT levels and down-regulation of TNF-α and IL-6 levels.

The Stata 11.0 software was used in the statistical analysis. The results showed that a total of 19 articles involving 1080 patients were included. It showed that TCM in combination with bisphosphonates can significantly relieve pain (RR=0.8079,95%CI =0.754-0.85,P <0.001), improve the activity of daily living (RR =0.787,95%CI =0.69-0.897,P <0.001), promote sclerotin reparation (RR =0.71,95%CI =0.52-0.96,P =0.026), and improve KPS (RR=0.7268,95%CI =0.61-0.85,0.58-0.81,P <0.001). It was concluded that TCM decoction in combination with bisphosphonates can significantly improve its therapeutic effect as well as improve the patients’ quality of life.

AIMTo investigate the effects of resveratrol (Res) on the proliferation of VSMCs induced by Ang I and the expression of calmodulin (CaM) and calcineurin (CaN) in the proliferation of VSMCs treated by Ang 1 and to discuss the mechanism.

METHODSRabbit arterial VSMCs were cultured in vitro and VSMCs were identified with the method of immunocytochemistry. A cell proliferating model of VSMCs induced by AngII was established. VSMCs were cultured for 4-8 passages. The experiments were randomly divided into control group, AngII group (0.1 micromol/L) and AngII + Res groups with different concentrations(20, 40, 80, 160) micromol/L. VSMCs proliferation was determined with MTT colorimetric method. CaM was detected with Coomassie brilliant blue method and CaN was determined by enzyme reaction phosphorus measurement.

RESULTSRabbit VSMCs were cultured successfully and could be passaged. After immunocytochemistry staining, all the cells cytoplasm were stained and positive. Cell proliferation, CaM and CaN activities were increased significantly in VSMCs proliferation induced by AngII (P <0.05, P < 0.01). The index of AngII + Res groups were obviously reduced compared with AngII group ( P < 0.01).

CONCLUSIONThe VSMCs proliferation induced by AngII can be inhibited by Res significantly, and the inhibiting mechanism of Res may be related to inhibiting CaM and CaN activities then restraining the proliferation of VSMCs in a dose dependent manner.

In order to study the the impact of cognitive difference between doctors and patients on doctor-patient relationship, five tertiary hospitals in city B were investigated with questionnaire and quantitative interviews, and the outcomes were analyzed with SPSS16. 0 software. Cognitive differences were found in the nature of the relationship, the main part of responsibility for the relationship, and principles for communication between the parties. By analyzing the causes of the difference and their impact on the relationship, it draw the conclusion that this cognitive difference found between the two parties functions as a key to the conflicts between doctors and patients. Return of health care back to non-profit nature, encouragement of patient-doctor communication and mutual understanding will be conducive to minimizing such a cognitive difference, and building a harmonious doctor-patient relationship.
