Insulin sensitivity index (SI).glucose effectiveness (SG) and insulin secretion function were assessed by modified minimal model method (MMM) with frequently sampled intravenous glucose tolerance (FSIGT) test in the controls, in patients with impaired glucose tolerance (IGT), and type II diabetes mellitus (NIDDM). There was significant correlation between modified MMM and standard MMM in evaluating SI and SG. The results indicated that SI and SG were significantly elevated in the control than in the IGT and NTDDM groups. SI diminished much more in IGT group than in NIDDM group (P

Objective Using solid dispersion technique to prepare Silymarin Dropping Pill to accelerate dissolution and to improve bioavailability. A central composite design-response surface method was employed to select the optimum formulations. Methods Independent variables were Poloxamer 188 content and silymarin content, while dependent variables were disintegrating time and percent of silymarin dissoluted at a definite time. Linear, two and three order quadratic models were used to estimate the relationship between independent and dependent variables. Response surfaces were delineated according to best-fit mathematic models and optimum formulations were selected there from. Prediction was carried out through comparing the observed and predicted values. Results Three order quadratic equation was the best-fitted mathematic models to describe the relationship between dependent and independent variables, with a regression coefficient of 0.998. Bias between observed and predicted values of disintegrating time and dissolution percentage of optimum formulation dropping pill were negligible, indicating the high predictability of the fit models. Percent dissolution of Silymarin Dropping Pill at 60 min was 19 times as that of conventional tablets. Conclusion Dissolution speed of silymarin can be effectively improved through incorporating into dropping pills. It shows that the optimum mathematic model is highly predictive. The central composite design-response surface method can be fairly used in formulation screening.

Background and purpose:Esophageal carcinoma is a common malignant tumor.Patients with esophageal carcinoma have a low survival rate.CD44 gene and CYP2E1 gene are related to invasion and metastasis of esophageal cancer,therefore we studied CD44 and CYP2E1 gene polymorphism in regard to its relationship with esophageal cancer. Methods :We analyzed CD44 and CYP2E1 genetic polymorphism in 45 cases with esophageal cancer and adjacent tissues by PCR technology. Results :CD44 protein was significantly over-expressed in tumor tissues than that in adjacent tissue(P

Objective: To explore the efifcacy and safety of sildenaifl for treating the patients of congenital heart disease (CHD) with severe pulmonary hypertension in plateau area.
Methods: A total of 50 CHD patients combining severe pulmonary hypertension treated in our hospital from 2010-01 to 2013-10 were studied. The patients were randomly divided into 2 groups, n=25 in each group. Control group, the patients received conventional treatment and Sildenaifl group, based on conventional treatment, the patients received additional sildenaifl medication. The hemodynamic, blood gas, routine and biochemistry were recorded and compared between 2 groups.
Results: Compared with Control group, Sildenaifl group had more reduction of pulmonary artery pressure, increased arterial pressure of oxygen, left ventricular output, cardiac index and oxygenation index, all P<0.05. The patients’ arterial pressure, blood routine and biochemistry were similar between 2 groups, P>0.05. There was no obvious adverse reaction observed in Sildenaifl group.
Conclusion: Based on conventional treatment, Sildenafil may effectively reduce the pulmonary artery pressure in CHD patients combining pulmonary hypertension in plateau area, it improving the cardiac function without adverse reaction.

Objective To conduct the diagnostic treatment in the children under 5 years old with suspected asthmatic disease and to evaluate its safety .Methods The children outpatients with suspected asthmatic diseas were selected and divided into the experi‐mental group and the control group according to odd days and even days .The conventiona therapy of anti‐infection ,relieving cough , reducing sputum and supporting treatment were administered in both groups .The experimental group was added tulobuterol tape . The cough relieve on daytime and nighttime ,initial effective time ,cough disappearance time and occurrence rate of adverse events at 24 ,72 h and on 5 d after treatment were compared between the two groups .Results The total effective rate of cough sysmptom re‐lief in the experimental group at 3 time points and nighttime was higher than that in the control group with statistical difference be‐tween the two groups(P < 0 .05) .The initial effective time had no statistically significant difference in daytime between the two groups(P> 0 .05) ,but which in daytime showed the statistically significant difference (P < 0 .05) ,especially the cough disappear‐ance time at nighttime in the experimental group was significantly shortened than that in the control group( P < 0 .05) .The oc‐curence rate of adverse events had no statistical difference between the two groups(P > 0 .05) .Conclusion Tulobuterol tape by transdermal delivery as one of diagnostic treatment measures for children under 5 years old with suspected asthmatic disease is defi‐nitely effective ,safe and convenient in application with the high compliance for children patients and acceptability by the family members ,obviously shortens the course of treatment ,which is worthy of being promoted .

UNLABELLEDOBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.

METHODSBy adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment. Patients in the JTXZC group took JTXZC, 4 pills each time, three times per day, while those in control group took Pioglitazone Tablet, 15 mg each time, once daily. The therapeutic course for all was 8 weeks. The body weight (BW), the height, body mass index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), and scoring of Chinese medicine (TCM) symptoms were observed. Levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), glycated hemoglobin (HbA1c), tumor necrosis factor alpha (TNF-alpha), nuclear factor kappaB (NF-kappaB), and plasminogen activator inhibitor 1 (PAL-1) were detected. The safety indices such as liver and renal functions and adverse reactions were also observed.

RESULTSCompared with before treatment, BW, BMI, HbA1c, and PBG were obviously lower after 8-week treatment than before treatment in the JTXZC group (P < 0.05). There was no statistical difference in post-treatment BW, BMI, HbA1c, or 2 h PBG between the two groups (P < 0.05). Compared with before treatment, levels of TNF-alpha and PAI-1 were lowered after 8 weeks of treatment in both groups (P < 0.01). The level of NF-kappaB was obviously lowered after 8 weeks of treatment in the control groups (P < 0.05), but it also decreased in the JTXZC group with no statistical difference. The scorings of CM symptoms were somewhat improved after treatment in the two groups (P < 0.01). Besides, better effects were obtained in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the whole therapeutic course.

CONCLUSIONSJTXZC showed similar therapeutic effect to pioglitazone. Both of them could effectively improve patients' clinical symptoms, the inflammation and fibrinolytic activities in different pathways, with no severe adverse reaction.

The higher medical education in China starts late and needs further exploration and improvement.While in Germany,it is elite education with a long history.Compared with China,in curriculum setting,Sociology,Medical health security,Humanities and Social Sciences and Organ system classification courses are more emphasized,and in terms of degree,it only has Doctor degree but with higher quality in Germany.Higher medical education in China will also take the path of the elite education.We can learn from the German medical education development experience and pay attention to solving the lack of the curriculum by supplementing social medicine and medical health security,increase the autonomy of the instructors in the training process,strengthen the medical students' social responsibility,and improve the quality of higher medical education in China.
