Objective To investigate the applications of antibacterial agents to outpatients in primary hos -pitals in Hefei City of Anhui Province,and to provide reference for rational use of antibacterial agents.Methods In 2011, fourty-five primary hospitals in Hefei City were selected randomly ,including urban community health service centers (Group A) and township hospitals(Group B),and thirty or fourty outpatient prescriptions were analyzed monthly . Results In Group A, the percentage and intensity of antimicrobial usage , the proportion of the combination and injectable formulation were ( 45.36 ±20.02 )%, ( 89.73 ±25.50 ) DDDs · ( 100 cases ) -1 · d-1 , 13.34%, 23.16%,respectively,and the data in Group B were (61.36 ±17.18)%,(108.46 ±32.27)DDDs· (100 cases) -1 · d-1,29.13%,46.39%,respectively,which the former were significantly lower than the latter.Conclusion In primary hospitals,the applications of antibacterial agents to outpatiants are not rataional ,including high percentages of usage and unreasonable selection of species ,and more supervision and training need to be given to the medical staff , especially in township hospitals .

Objective To investigate the risk factors of hepatitis B virus (HBV) reactivation after microwave ablation (MWA) and its prevention.Methods 72 patients who met the inclusion criteria were enrolled into the study.30 patients were in the control group and 42 patients in the prophylactic antivirus group.Results 8.3％ (6/72) patients developed HBV reactivation.A high HBV DNA load and no prophylactic antivirus therapy were independent risk factors of viral reactivation.Conclusion Prophylactic antivirus therapy can prevent HBV reactivation.

AIM:To study testicular pathological change and its pathogenesis. METHODS:Testicular structure of alloxan induced diabetic rats was observed under light microscopy (LM)and transmission electron microscopy(TEM). Activity of superoxide dismutase(SOD),glutathione peroxidase(GSH-PX)，nitric oxide synthase(NOS)and content of malondialdehyde (MDA),nitric oxide(NO) were detected biochemically in testicular homogenate. RESULTS:It is manifestated as atrophy of seminiferous tubule and germinal arrest under LM and expansion of mitochondria and smooth endoplasmic reticulum, cytoplasmic inclusion of sertoli cell under TEM.Activity of SOD, GSH-PX decreased while activity of NOS, content of MDA, NO increased in diabetic rats compared with control one. CONCLUSION:Disturbance of spermatogenesis and damage of sertoli cell are the main morphological change of diabetic testis, lipid peroxidation and NO may be involved in it.

Objective To explore the clinical characteristics,therapy reactions and prognosis of the elderly patients with idiopathic thrombocytopenic purpura(ITP). Methods A total of 43elderly ITP patients(age≥60 years old)including 16 men and 27 women were reviewed and further followed up for 1 month to 15 years. Results Until June 2007,35 elderly ITP patients survived,platelet counts were sustained(30-50)×109/L in 7 cases,but no significant bleeding was found.Thirty-six patients had adrenocorticosteroid therapy first, 25 patients were sensitive to adrenocorticosteroid therapy,4 patients underwent splenectomy,and 3 patients achieved a normal platelet count. Immunosuppressive agents(vinscristine,cyclophosphamide, azathioprine and Cyclosporin A)treatments were held in 5 6 case-times,Cyclosporin A and azathioprine were more effective than vinscristine and cyclophosphamide.The refractory rate was 13.9%.One patient progressed to monoclonal gammopathy of unknown significance and 1 to lymphoma.Eight patients died.1 patient died of brain bleeding after trauma,3 patients died of malignant neoplasm,4 patients died of heart failure induced by infection. Conclusions The clinical features of elderly ITP patients are atypical.the mortal bleeding in them was rare,treatment strategy should be individualized tO each elderly patient.

Objective Neuroinflammation following traumatic brain injury (TBI) may give rise to neurodisorder.This study aimed to investigate the effect of intranasal delivery of nerve growth factor ( NGF) on neuroinflammation following TBI and its action mechanism in rats. Methods Thirty-six male adult Sprague-Dawley rats were equally divided into a sham , a TBI, and a TBI+NGF group.The rats in the TBI +NGF group were treated with NGF intranasally at 12 and 24 hours after TBI.The levels of IL-1βand TNF-αin the injured cerebral cortex were detected by ELISA , the DNA-binding activity of NF-κB evaluated by EMSA , and the expres-sion of amyloid-β( Aβ42 ) determined by Western blot . Results NGF attenuated the inflammation following TBI .Compared with the TBI group, the level of IL-1βwas obviously decreased in the TBI +NGF group at 12 hours (70.65 ±3.10 vs 37.51 ±1.92) and 24 hours (68.85 ±8.10 vs 36.23 ±2.99, P<0.05), and so was that of TNF-α(47.12 ±7.38 vs 27.63 ±5.77 and 56.15 ±11.20 vs 29.94 ±8.62, P<0.05).The DNA-binding activity of NF-κB was reduced to 111.62 ±0.49 and 131.52 ±0.88, and the expression of Aβ42 to 0.23 ±0.008 and 0.52 ±0.004 at 12 and 24 hours respectively after treatment with NGF , both with statistically significant differences from the TBI group (P<0.05). Conclusion Intranasal administration of NGF attenuates TBI-induced neuroinflamma-tion in rats, which may be associated with its regulatory effect on the Aβ42/NF-κB signaling pathway .

Growth patterns of trichome and contaminative bacteria in Spirulina sp. liquid culture were observed, and it was found that the number of neutral and alkalophilic bacteria was always 105～106 times of that of Spirulina sp. trichome. It would be very difficult to get real pure Spirulina sp. strain by classical methods of dilution plate, capillary and single trichome selecting methods. A great deal of contaminative bacteria was washed out by two pretreatment processes. Low speed centrifugation was designed to wash the strains which usually deposit at bottom, and filtration method was designed to treat the strains usually floating at surface. Sandwich plate and dilution plate were designed for the purification of the mobile strains and non-mobile strains, respectively. A lot of strains were purified by the above processes and pure single trichome formed pure colonies on plates.

Objective To evaluate the efficacy of radiosynovectomy with 32P colloid in haemophilic synovitis of adolescents. MethodsRadiosynovectomy with 32P colloid was primary performed on 26 male haemophilic patients(26 joints),whose average age was 16 years(11 to 21 years).The average dose of 32P colloid was 2.1 mCi(1.0 to 3.0 mCi). Results After 6-month interval,haemarthrosis was reduced by no less than 30% in 23 patients,with a total efficacy of 88.5%.The mean frequency of haemarthrosis was reduced from 1.9 per month of presynovectomy to 0.3 per month of postsynovectomy(P
