Objective To evaluate the outcomes after implementing gestational diabetes mellitus(GDM) specialist practice model. Methods GDM specialist practice model contained four modules(first visit,follow-up visit,hospital-ization,postpartum),eight aspects of practice contents which included specialist evaluation,diet & exercise survey, diet & exercise prescription,GDM health guidance,weight management during pregnancy. Pregnancy outcomes were compared before and after GDM specialist practice. Results GDM specialist practice model was able to signifi-cantly decrease insulin utilization rate,reduce number of hospitalized patients due to poor blood sugar control,short-en length of hospitalization. Conclusion GDM specialist practice model can effectively save medical costs,and GDM specialist nurses play an important role in management of women with GDM.

Objective To explore feasibility of laparoscopic hepatectomy for hepatic hemangioma.Methods Twelve patients were treated by laparoscopic hepatectomy, including left lateral lobectomy in 5 cases and local liver resection in 7 cases. Three cases of hepatic hemangioma associated with gallbladder stone were performed cholecystectomy synchronously. Results Laparoscopic procedures were successfully performed in all 12 cases. The mean operative time was 155 min. The mean blood loss was 230 mL. The mean postoperative hospital stay was 8 days. The pospostoperative recovery was smooth except that 1 case had pulmonary infection. During a follow-up of 6-20 months for 12 cases,there were no recurrence. Conclusion Laparoscopic hepatectomy for hepatic hemangioma is safe and feasibile with good effect under the condition of strict indication selection and experienced surgeons operating.

In surgery operations, wound should be cleaned with warm sterilized saline solution. In order to reach rapidly warming the washing solution from the room temperature during the surgery, we designed a thermostatic medical infusion pump. The present paper mainly presents researches on the two temperature control methods in the standby mode and in the flushing mode of the system. In the standby mode, the traditional proportional-integral-derivative (PID) control algorithm was adopted. In the flushing mode, dynamic characteristics of the system was changed in real time, which made the thermostatic control process more complex, and the fitted control function combined with the PID control algorithm was adopted in this mode. The temperature control parameters were adjusted in real time according to the initial temperature and the flow rate of the washing solution to obtain a constant temperature of the washing solution, no matter how the initial temperature and the flow rate are changed. The experiment results showed that this kind of control system performed well with a high accuracy.

Objective　To Compare the anti hypertensive effects of felodipine and amlodipine on 24 hours blood pressure in patients with essential hypertensin. Method A Radomized， single blind and contro11ed study was perfo rmed and blood pressuree was measured by 24 hours ambulatory blood pressure monitoring. Results Felodipine and amlodipine signiflcantly reduced both s ysto1ic and diasto1ic casual b1ood preessure when compared with placebo and no differences were observed between the two drugs． Felodipine and amlodipine reduce 24h mean，daytime mean ambulatory blood pressure．The rapid rise in blood pressure i n the morning hours was well contro11ed by the two drugs. Conclusion:Felodipine and amlodipine used once daily could cont rol 24 h blood pressure effectively in patients of essential hypertension．

Objective:To study the function of transcription factor 4 (TCF4) and to prepare TCF4 polyclonal antibody.Methods:pET-41/TCF4 was transformed into E.coli BL21(DE3) and induced by IPTG.The purified GST-TCF4 fusion protein was applied to immunize rabbit to produce antiserum. The specificity of the affinity of purified anti-TCF4 antibody was examined by Western blotting analysis of the eukaryotic expressed products of TCF4. Dig-labeled probe and antibody against TCF4 were used to examine the expression of TCF4 in Saos-2 cells under mechanical stretch. Results:Western blotting showed that the antibody could bind to TCF4 specifically. The expression of TCF4 mRNA and protein were significantly increased in Saos-2 cells under mechanical stretch. Conclusion: TCF4 antibody has been prepared successfully.

The angiotensinogen(AGT) expression and angiotensin Ⅱ (AngⅡ ) secretion levels in cultured SD rat mesangial cells were determined. High glucose up-regulated AGT mRNA(0. 29±0.07 vs 0. 20±0. 05,P< 0.05)and protein(0.66±0.23 vs 0.37±0. 15,P<0.05) expression and Ang Ⅱ secretion [(9.85±2.08 vs 7.50± 1. 51) pg/ml,P<0. 05]levels, which were down-regulated by pyrrolidine dithiocarbamate( PDTC) treatment via inhibiting NF-κB activity.

OBJECTIVE:To establish a HPLC method for a simultaneous determination of moxifloxacin hydrochloride and ephedrine hydrochloride in compound moxifloxacin nasal drops.METHODS:The separation was performed on VP-ODS chromatographic column with column temperature at 30℃. The mobile phase consisted of phosphate buffer solution (which contained 0.02mol?L-1 sodium dihydrogen phosphate and 0.3% triethylamine, adjust pH to 3.0 by phosphoric acid) - methanol(60∶40) with flow rate at 1.0mL?min-1, detection wavelength at 214nm and sample size at 20?L. RESULTS: The linear ranges of moxifloxacin hydrochloride and ephedrine hydrochloride were 0.1～0.8(r=0.999 7,n=5) and 0.125～1.000?g (r=0.999 9, n=5), respectively,and their average recoveries were 98.94% (RSD=0.89%) and 99.67%(RSD=1.26%),respectively.CONCLUSION: The technique is simple, rapid, accurate, and reproducible, and it can be used as the quantity control of compound moxifloxacin nasal drops.

Objective:To analyze the effects of essential medicine system on revenue structures at primary med-ical institutions. Methods:Data on revenue status and structures from 58 township health centers in Shanxi Province was collected to analyze changes and trends. Results:Along with growing government investments in primary medical institutions, the essential medicine system has fundamentally realized full coverage. The percentage of essential medi-cine revenue to pharmaceutical revenue rose from 20 . 45% in 2009 to 97 . 03% in 2013 , though the percentage of pharmaceutical revenue to total revenue dropped by 18 . 43%. The percentage of fiscal subsidy revenue in total reve-nue rose from 25 . 77% in 2009 to 54 . 16% in 2013 , though the percentage of business revenue to total revenue dropped in general. Conclusions:The essential medicine system requires the government’s financial support. Essen-tial medicine lists and primary financial aid policies should be further improved;doctor reimbursement and incentive mechanisms should be improved as well and unreasonable doctor service pricing and reimbursement mechanisms should be reformed.

Objective:To investigate the effectiveness of irbesartan in combination with ramipril for treatment of chronic heart failure in patients with rheumatic heart disease(RHD).Methods:A total of 120 RHD patients with chronic heart failure were randomized into treatment group(n=60)and control group(n=60)after valve replacement.All patients received regular ramipril treatment(5 mg/d);treatment group were also given irbesartan(150 mg/d).The patients were followed up for 6 months.The indices of observation included cardiac function(NYHA Class),6-Minute Hall Walk distance,and echocardiographie parameters.Results:Six months later the cardiac function in the treatment group was obviously improved compared with the control group;the patients in the treatment group had significant increase in 6-Minute Hall-Walk distance and improvement in echocardiographic parameters(left ventricle end-systolic diameters,end-diastolic diameter,ejection fraction, fractional shortening,P
