OBJECTIVE:To provide reference for the rational clinical prophylactic use of antibiotics. METHODS:The cases in whom the clinical prophylactic use of antibiotics between 2006 and 2007 in our hospital showed failure in efficacy were monitored to analyze the cause of failure,meanwhile the clinical samples were sent for culture,isolation,identification and drug susceptibility tests as well as drug resistance analysis. RESULTS:Cephalosporins,Quinolones,Penicillins,Cefhalosporins + enzyme inhibitor were more commonly used antibiotics in our hospital,with drug resistance rates at 57.21%,65.14%,68.63%,and 18.81% respectively. Among the total 240 cases monitored,the prophylactic use of antibiotics totaled 877 times,of which,388 (44.24%) were non-indicated drug use,459 (52.34%) showed drug resistance,286 (32.61%) involved improper drug choice,and 42 (17.50%) showed dual infection. CONCLUSION:The clinical prophylactic use of antibiotics in our hospital is far from perfect; therefore,it is urgent to tighten control on the standard prophylactic use of antibiotics.

In order to set up a base for stem cells to be widely used in clinical medicine, we tried to optimize, in this study, the technique that induces human mesenchymal stem cells (hMSCs) to differentiate into neural stem cells by using cerebrospinal fluid (CSF) from the different groups. After the induction, presence of neural stem cells was confirmed with microscope observation, flow cytometry analysis, immunohistochemistry and fluorescent immunohistochemistry. At the same time, we also compared and analysed the data of the number of stem cells when it totally met the requirements for clinical treatment and the days required. At last, we confirmed that hMSCs could be induced to differentiate into neural stem cells, and that the number of cells totally met the requirements for clinical treatment. But there were some differences both in the number of cells and the days required. Among the groups, the group that marrow mesenchymal stem cells from patients own induced by CSF from healthy volunteers used the shortest time and the quantity of the cells was significantly higher than those of the others.

Objective To summarize the experience on diagnosis and treatment of splenic neoplasm. Methods Clinical data of 40 patients with primary splenic space occupying lesion treated in our hospital were retrospectively analyzed. Results Thirty four out of the 40 cases were diagnosed as primary splenic neoplasm preoperatively. The detectable rate of B-US was 94%, and that of CT was 96%. The discrimination rate of benignancy and malignancy by CT was 84%. Serum AKP and ?-GT were significanfiy increased in most of the malignancies. Seventeen among 22 cases with benignancy were treated by splenectomy, and the others underwent partial splenectomy or tumor resection. Sixteen of 18 patients with malignancy underwent splenectomy, and two did biopsy. Pathology revealed cysts in 13, angiocavernoma in 4, inflammatory pseudotumor in 3, caverous lymphangioma in 1, and cystic degeneration of liomyoma in 1; malignant lymphoma and lymphsarcoma in 9, hemangiosarcoma in 3, and fibrosarcoma, liomyosarcoma, malignant fibrous histiocytoma in 1 each. Three cases with malignancy have survived more than 5 years. Conclusions Splenic neoplasm is diagnosed mainly according to clinical manifestation and image examination. The discrimination of benignancy and malignancy depends on CT, angiography, and serous AKP and ?-GT level. Radical operation and complex treatment could improve the prognosis of splenic malignant tumor.

To study the effect of chinese herbal medicine preventing gallstone formation, morphology of livers and gallbladders as well as conjugated bile acids of the bile. 58 female guinea pigs were randomly divided into three groups. The control group was fed on normal diet; the lithogenous groups was high cholesterol diet (HCD) and the antilithic group was high cholesterol and the chinese herbal medicine capsule (13.5 g/kg). 8 weeks later the guinea pigs were killed. Liver and gallbladder were removed for light and electroscope observation. Gallbladder bile were withdrawn and gallbladder were collected. The minute construction of gallstones were observed by scanning electron microscope and gallstone components were quantified by Fourier Transform Infrand Spectros Copy (FT-IR). The morphology of liver and gallbladder were observed by light microscope and transmission electron microscope. Conjugated bile acid of biles were determined by Thin-layer Chromatograph. The effect of chinese herbal medicine preventing gallstone formation, morphololgy of livers and gallbladders as well as conjugated bile acids of the bile were also observed. We measured conjugated bile acids in all groups and found that decreased in lithogenic group and increased notably in antilithic group (P<0.01). The gallstone formation rate was 100% when the animals were fed on HCD in lithogenic group. The rate decreased to 5.3% when the animals were fed on HCD and Chinese herbal medicine capsule inantilithic group. It indicates that changes in diet is an important factor in the process of gallstone formation and the chinese herbal medicine can prevent gallstone formation effectively.

This study was aimed at evaluating the antioxidant activities of methanol extract of Thamnolia vermicularis. The antioxidant activity, reducing power, superoxide anion radical scavenging and free radical scavenging activities were studied. The antioxidant activity of the extract correlated with its concentration (0.2~2 mg/ml) in the reaction mixtures containing linoleic acid. Upto 67% of lipid peroxidation was inhibited by 2 mg/ml of the lichen extract. The extract showed strong free radical scavenging activity similar to that of BHA (positive control) in a manner of concentration dependent. The lichen extract also showed moderate effects on superoxide anoin scavenging activity and reducing power, which was not so effective as that of Quercetin and BHA used as positive controls. This study suggests that T. vermicularis lichen can be used as a novel source of natural antioxidant.
