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.

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: 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.

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 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 .

OBJECTIVETo observe the clinical efficacy and safety of sildenafil in the treatment of high altitude heart disease associated with severe pulmonary arterial hypertension (PAH) in children.

METHODSFifty children (aged 2 months to 2 years) with high altitude heart disease associated with severe PAH, who were continuously transferred to the Intensive Care Unit between January 2011 and October 2013, were randomly assigned to observation and control groups. The control group was given conventional treatment, while the observation group received oral sildenafil [1 mg/(kg . d)] three times daily for 7-10 days in addition to the conventional treatment. Before and after treatment, hemodynamics, blood gas, routine blood parameters, and blood biochemical parameters were recorded.

RESULTSAfter treatment, the observation group had a significantly higher decrease in mean pulmonary artery pressure and significantly higher increases in arterial partial pressure of oxygen, cardiac output, cardiac index, and oxygenation index compared with the control group (P<0.05). In the observation group, there were no significant changes in mean arterial pressure, routine blood parameters and blood biochemical parameters (P>0.05), and no obvious adverse reactions were found.

CONCLUSIONSFor children with high altitude heart disease associated with severe PAH, sildenafil can effectively reduce pulmonary artery pressure and improve cardiac function and does not cause adverse reactions. This therapy has good safety according to the preliminary evaluation.

Objective To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) with scissors knife in difficult cases.Methods A total of 36 sessions of ESD in 34 patients were performed from May 2010 to May 2012 with application of new scissors knife.The complications and followup outcomes were recorded.Results All lesions were removed successfully with an en bloc resection rate at 91.7％.Delayed bleeding occurred in 2 patients (5.6％),and both of them were cured sucessfully with endoscopy.No perforation happened and the average hospitalization time was 5 days.Follow-up endoscopy performed 6 or 12 months after ESD in 6 patients revealed no recurrence or residual lesions.Other patients are under follow-up now.Conclusion The scissors knife is easy to manipulate,which can ensure the safety and efficiency of ESD.
