OBJECTIVE:To explore optimal regime and less ADR for lupus nephritis(LN) by adopting self-made TCM prescription.METHODS:109 LN patients were assigned into control group(n=48) and therapy group(n=61).Both groups were treated with metacortandracin and cyclophosphamide.Control group were additionally given self-made TCM prescription.The clinical efficacy and adverse drug reaction(ADR) of 2 groups were compared.RESULTS:The curative rate and total response rate of therapy group were 77.05%(47/61) and 95.08%(58/61) respectively and those of control group 58.33%(28/48) and 77.08%(37/48).The curative rate and total response rate of therapy group were all higher than those of control group.There were significant difference between 2 groups(P

OBJECTIVE To investigate the ?-lactamases producing rate in Haemophilus influenzae(HIN) and the antibiotics sensitivity,to guide the treatment of Haemophilus species infection.METHODS The strains from respiratory tract samples,were isolated and cultivated in chocolate cultures 2006 to 2007.Drug sensitivity test and beta-lactam enzyme test of Haemophilus species were taken.The results were analyzed by software SPSS11.5.RESULTS Totally 195 isolates of HIN were isolated 32 produced ?-lactamases(16.4%).The sensitivity of H.influenzae to cefuroxime,cefotaxime and ampicillin/sulbactam was 90.8%,93.8% and 95.4%,respectively.CONCLUSIONS Cefotaxime,ampicillin/sulbactam and cefuroxime are the most effective antibiotics for H.influenzae infection.

Pulmonary arterial hypertension (PAH) is an incurable fatal disease, with the mechanism of imbalance of vascular contraction and relaxation which start as a series of pathophysiological reactions. Angiotensin-converting enzyme 2-angiotensin (1-7)-G protein-coupled receptor axis [ACE2-Ang(1-7)-Mas], an expanded vascular axis which is considered as new axis of renin-angiotensin system (RAS) is a negative regulator of the classical angiotensin-converting enzyme-angiotensin Ⅱ-angiotensin Ⅱ type 1 receptor axis (ACE-AngⅡ-AT1R), a contraction vessel, proliferation axis. A retrospective study concerning the pathophysiological mechanism of ACE2 in the treatment of PAH was done and found that ACE2-Ang-(1-7)-Mas axis could reduce PAH induced by monocrotaline (MCT) through declining the inflammatory cascade, improving endothelial dysfunction and regulating autonomic nerve, reduce PAH induced by hypoxia through inhibiting the proliferation of pulmonary artery smooth muscle cells and reduce PAH induced by congenital heart disease. Therefore, ACE2 may become a future drug of preventing and treating PAH.

Objective To investigate the serum lipoprotein (Lp) (a) level in patients with acute ischemic stroke and the prediction for short-term functional outcome. Methods The levels of serum Lp(a) were measured in 210 patients with acute ischemic stroke (within 24 h after onset) and 100 healthy people matched the gender and age. The patients were assessed with National Institutes of Health Stroke Scale (NIHSS) as admission, and modified Rankin Scale (mRS) as discharge. Results The median of Lp(a) was 325 mg/L (IQR: 180~545) in patients,significantly more than 148 mg/L (IQR: 69~265) in the normal controls (P<0.001). Level of serum Lp(a) was an independent variable for functional outcome (OR=1.004, 95%CI: 1.001~1.007, P<0.001) and death (OR=1.006, 95%CI: 1.001~1.008, P<0.001) in patients. In the receiver operating characteristic curve, the area under curve was more in the combined model [Lp(a) and NIHSS] than the NIHSS alone.Conclusion Serum Lp(a) increased in the in patients with acute ischemic stroke, and may predict the short-term outcome independently.

Objective To optimize the extraction conditions of Hyperici Perforate Herba, Coptidis Rhizoma, Schisandrae Chinensis Fructus, and Ziziphi Spinosae Semen forJinzao Yuanzhi Capsule.Methods Hyperin extraction rate was set as index, and HPLC was used for determination. The extraction conditions of ethanol concentration, ethanol quantity, extraction time and other factors were studied with orthogonal test and comparative test.Results Ethanol concentration and extracting times were remarkable factors in the test. The optimum extraction technology forJinzao Yuanzhi Capsule was to reflux and extract the materials with 8 times of 70% ethanol for 2 times, reflux extraction for 1.5 hours, filtration. Then 6 times of 70% ethanol was added for 1.5 hours’ reflux, filtering, and merging extracted liquid.Conclusion The optimum extraction technology is reasonable and feasible.

Objective To explore drug abuse prevention measures by surveying the changes before and after methadone maintenance treatment(MMT). Methods The baseline survey data were obtained from patients who participated in the MTT program for the first time at Wuhan First Health Clinic of Mental Health Center Affiliated to Tongji Medical College between March 2006 and December 2013,and the general conditions of these patients were analyzed. Results There were 1 186 drug abusers, with a male and low education(junior high school and below)dominance. After the initiation of the MMT program,the number of addicted people was highest in 2008,and then gradually decreased after 2009.MMT program achieved obvious social benefits.The proportion of injectable drug use alone was decreased and the rates of oral drug use and snorting were increased over time.Fixed salary and temporary salary were obviously increased in drug abusers after 2009. Daily drug cost was decreased over time. The proportion of community/ media propaganda through which people got to know MMT remained low. Conclusion The community support and educational propaganda should be strengthened at the same time when MMT is carried out.

Objective The purpose of this study was to investigate the effect of blood supply decrease on glycosaminoglycans(GAG)of the cartilage in the temporomandibular joint(TMJ) . Method Four rabbits were used as controls, and 16 rabbits were injected 5% sodirm morrhumate through carotid artery unilaterlally. All specimens were examimined histochemically. Result A reduction in alcian(AB) blue staining was observed after operation, a gradual increase in AB staining with blood supply restoration of TMJ tissue was observed. Conclusion The result suggests that the decrease in blood supply of the temporomnandibular jorint leads to the loss of GAG in the condylar cartilage, which may play an important role in pathogenesis of osteoarthrosis.

The in vitro antitumor activity of bakuchiol was exploited, compared with tamoxifen. The result of biological activities showed that bakuchiol could inhibit human breast cancer and the IC50 values were 2.89 x 10(-5) mol L(-1) and 8.29 x 10(-3) mol L(-1) against the cells line T-47D and MDA-MB-231 respectively. On the other hand, the key intermediate to synthesize bakuchiol was obtained by the method of Ireland-Claisen rearrangement. Comparing with traditional Claisen rearrangement, the reaction conditions are milder and the reaction reagents are safer.

Objective To investigate effect to kill primary breast cancer cells by dendritic cell (DC)with self-freeze thawing antigens of primary breast cancer cells co-cultured with cytokine induced killer cell (CIK). Methods Self-neoplasm antigen by primary cells of breast cancer in log phase growth was prepared and DC and CIK cells was cultured from peripheral blood. The CIK of co-cultured DC loaded self-neoplasm antigen was compared to PBMC, CIK cells with self-neoplasm antigen and the single CIK cells. Results Killing efficiency of PBMC, CIK, Ag-CIK and Ag-DC-CIK were (34.35±3.28) %, (45.91±2.78) %, (50.88±3.22) %, (62.10±5.94) %. There were significant difference between Ag-DC-CIK group and CIK-Ag and CIK group to primary cells of breast cancer (P <0.01). Conclusion The CIK induced from cocultured DC loaded with self-neoplasm antigen show a special killing activity to self-primary tumor cells.
