Objective:To observe the clinical effect and safety of diammonium glycyrrhetate(DG) in the treatment of psoriasis vulgaris.　Methods:48 patients were randornly divided into two groups treated group(28 cases)and controlled group(20 cases). Both were given DG or common drugs, respectively.　Results:Effective rate was 67.9%(19/28), mean effect-begining time was 17.42±2.36 days in the treated group, they were significantly increased in comparison with controlled group(Effective rate was 30.0%, mean effect-begining time was 25.65±3.54 days). Any side effect was not occurred in treated group. 　Conclusion:DG is effective and safe in the treatment patients with psoriasis vulgaris.

The therapy course of both groups were 30 days.　Results:The total effective rate of two groups was 82.2%. The effective rate of A group and B group were 88.9% and 73.1%, respectively. There was siginfinant difference by the analysis(ridit test)between two groups(U＝2.76，P＜0.01).　Conclusion:The effect of He-Ne laser combined with ammonium glycyrrhetate in the treatment of patients with psoriasis vulglar than that of ammonium glycyrrhetatealone.

Objective: To observe the effectiveness of combinative use of gentamycin, metronidazole and rifampin in the treatment of ulcerative colonitis and explore the etiology of the disease.　Methods: 30 and 26 patients were allocated to treatment group and control group, respectively. Maintained clysis with a combination of gentamycin, metronidazole and rifampin in warm normal saline were administered to those in the treatment group twice a day for two weeks, while SASP and prednisone were administered to those in the control group for two weeks.　Results: The alleviation rate of the treatment group is higher than that of the control group.　Conclusion: Combinative use of gentamycin, metronidazole and rifampin for maintained clysis is a effective treatment for ulcerative colonitis.

Objective: To improve the safety of anesthesia of the neonates at high risk during surgical operation. 　Methods:Before the operation, Anisodamine, Ketamine and Vecuronium bromide were injected intravenously with dosage of 0.06mg, 2mg*kg-1 and 0.08-0.1mg*kg-1, respectively. Tracheal cannula or topical anesthesia using 1% of lidocaine hydrochloride was performed. The tracheal cannulation was performed after administration of sodium hydroxybutyrate and Ketamine by injection with dosages of 50-80 mg*kg-1 and 2mg*kg-1 body weight. Anesthesia apparatus and combinative anesthesia were used. The concentrations of SpO2 were monitored during the operation. A dosage of 1-2mg*kg-1 body weight was used for resuscination of the patients after the operation. 　Results: A total of 100 cases of operation were performed using the regime of anesthetic intervention described above. A 100% of success rate was achieved and no death occurred during the operation. 　Conclusion:Significant improvement of safety in anesthesia of the neonates at high risk during surgical operation can be achieved with sufficient preoperational preparation, adequate monitoring during the operation and rational use of anesthetics as well as restrict selection of suitable anesthetical interventions.

Objective:To evaluate the clinical effects of clindamycin injection on respiratory tract infections. 　Methods:Clindamycin injection was used in 50 respiratary tract infections patients aged over 18 years by intravenous drip with a dosage of 1.2 g once a day for a consecutive of 10 days. The symptoms and signs of the patients were observed, and the laboratory tests made.　Results: The numbers of patients who were cured, remarkably improved, improved and without any improvement were 25, 19, 5 and 1, respectively. The total effectiveness rate was 98.0%.　Conclusion: Clindamycin injection is significantly effective for treating the mild to moderate respiratory tract infections, especially for those caused by haemolytic streptococcus, streptococcus pneumoniae and lamellar bacillus. It has very little and mild side effects and is suitable for those allergic to penicillin.

Objective: To observe the effects of erigeron injection on the biochemical indicators of hepatotoxicity caused by ischemia and reperfusion of the mice intestine.　Methods:A experimental model of liver lesion induced by ischemia－reperfusion of the mice intestine was set up. Serum was obtained after 20 minutes of ischemia followed by 1 hour of reperfusion. Contents of SOD and MDA in liver were measured.　Results: The serum ALT significantly increased following ischemia and reperfusion, which was attenuated by the erigeron injection (P＜0.01). Erigeron injection can also increase the contents of SOD and MDA in the mice liver (p＜0.05 and 0.01, respectively).　Conclusion: Erigeron injection can improve the biochemical indicators of liver lesion induced by ischemia and reperfusion of the mice intestine. It is indicated that the protective effects of erigeron injection was related to anti－oxidation mechanisms.

Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.

Objective To observe the protective effect of meicha protein on the heart of spontaneously hypertensive rats(SHR),and explore its mechanism.Methods Fourty healthy SHR rats were randomly divided into 4 groups:model control group,Meicha protein low dose group(70 mg·kg-1)、Meicha protein high dose group(140 mg·kg-1),Compound Kendir Leaves Tablets group(50 mg·kg-1),n=10.The rats were orally administered twice daily by gavage for seven weeks,measuring blood pressure in each group fort nightly.1 h after the last administration,drawing off the blood from carotid,stripping off the heart tissue,and the organ index was calculated;Taking a part of the tissue with 4% paraformaldehyde for Pathological histology.Detection of serum NO,ET-1 levels as well as the organization of the ACE and Ang II mRNA expression to explore the mechanism of its buck.Results Meicha protein could significantly reduce the blood pressure of SHR;The impact on the rat organ coefficient was not obvious,but had a protective effect on heart tissue.Compared with the model control group,the contents of NO an ET-1 were significantly increased(P<0.01).Compared with the model group,the high dose of Meicha protein could induce ACE,AngⅡ,CYP11B2.The expression of mRNA was significantly decreased(P<0.01).Conclusion The possible mechanism of Meicha protein antihypertensionis relevant to increase the content of NO in serum,reduce the content of ET-1 in serum,reduce mRNA expression of ACE and AngⅡin cardiac tissue.

Objective To evaluate the uncertainty for the determination of salicylic acid in human plasma by ultra performance liquid chromatography(UPLC).Methods All sources of uncertainty in the whole process of salicylic acid determination were analyzed,then the combined and expanded uncertainty were evaluated.Results The expanded uncertainty at concentrations of the lowest limit of quantitation(0.23 μg·mL-1) and a high level(39.43 μg·mL-1) of salicylic acid(P=95%,k=2) was 0.014 and 7.34 μg·mL-1,respectively.Conclusion The uncertainty of salicylic acid determination in human plasma by UPLC was mainly caused by recovery,repeatability and sample preparation at the lowest limit of quantitation and high qulity control concentration.
