OBJECTIVE:To study the correlation between the rate of inpatients using antibacterials and the cross-sectional rate of inpatients using antibacterials.METHODS:A cross sectional study was conducted on the use of antibacterials in 1040 inpatients between May 22 and May 23 in 2007.Besides,the discharge case histories of 100 cases were collected randomly for an analysis.RESULTS:Of the total 1 040 inpatients,510(49.04%)used antimicrobials.The rate of inpatients using antibacterials in comprehensive ICU took the lead at 100%,followed by pediatric department(86.05%)and the department of nephrology(84.62 %).The average rate of inpatients using antibacterials in surgery department was significantly higher than in the department of internal medicine(63.52% vs.33.94%).81% of the discharged cases used antibacterials.The irrational use of antibacterials manifested as improper timing of medication,prolonged use of antibacterials for prophylactic purpose etc.CONCLUSION:The proportion of the patients using antibacterials in descending order were inpatients,cross-sectional inpatients and outpatients.It is necessary to tighten control on the rational use of antimicrobials.

ObjectiveTo introduce the progressing history of DO technique,and report the characteristics of the home-made type MS-1 internal mandibular distracter, and the effects of application of it in animal experiment. Methods15 Mongrel dogs were subjected to be lengthened of the unilateral or bilateral mandibles using the home-made type MS-1 mandibular distracter, and the regular X-ray ex aminations were made. ResultsAbout (20±5)mm in length of the andible had been achieved by the DO (distraction of osteogenesis)technique using the device. The accuracy of the distracter on lengthening would be attained to 98 % of the expectancy. The mineralization of the new bone fulfilled the gap zone about 5 weeks after the distraction had been finished during the consolidation period. ConclusionThe MS-1 type internal mandibular lengthening device has its special advantages on ap plication of cranio-maxillofacial surgery with a great expectancy.

Objective To establish a method for the determination of silybin in Fufang Yiganling tablet. Methods RP-HPLC was used and the mobile phase was consisted of methanol-water-glacial acetic acid (48∶52∶1). The detection wavelength was 286 nm. Results The calibration curve of Silybin was linear in the range of 0.238 0～2.380 ?g, linear equation:Y=2.146?106X +1.818?103, r=0.999 9, with average recovery of 98.17% (RSD=1.3%). Conclusions The method is simple, accurate and with good reproducibility. It can be used to control the quality of silybin in Fufang Yiganling tablet.

Cholangiocarcinoma is a rarely malignant tumor with poor overall prognosis. Radical surgery is the only strategy to improve the long-term survival of patients with cholangio-carcinoma of early-stage. For most patients with advanced cholangiocarcinoma, systematic treatment has become the main strategy. But the available first-line drugs for the treatment of cholangiocarcinoma are limited and the curative effect is limited. In recent years, immunotherapy strategies such as immune checkpoint inhibitors have achieved encouraging results in a variety of solid tumors by using the host immune system to carry out effective anti-tumor responses. The authors summarize the research advances of immune checkpoint inhibitors in the treatment of cholangiocarcinoma.

Objective To investigate radiation-induced alternations of phospholipids in epithelial cells,and to provide experimental evidence for understanding the mechanism of radiation-induced intestinal injury.Methods The intestinal epithelial cells(IEC-6)in rats were divided into three groups:normal control group,8 Gy X-ray irradiation group and 12 Gy X-ray irradiation group.Phospholipids were extracted at 6 h or 24 h after radiation and then measured by high-performance liquid chromatography and mass spectrometry(HPLC-MS).Results At 6 h after radiation,the phospholipids in 8 Gy irradiation group didn't vary significantly,while those in 12 Gy irradiation group changed.The PG,PI and Lyso PC were significantly up-regulated(F=5.37,9.60,9.88,P＜0.05).However,at 24 h after radiation,many PE and PG species in both irradiation groups declined(F=5.15-99.77,P＜0.05)and SM species increased in 12 Gy irradiation group(F=4.35-7.92,P＜0.05).Conclusions The ionizing radiation could disorder phospholipid metabolism in IEC-6 cells with a dose-dependent manner.

Objective To investigate the clinical efficacy of different treatment in 35 chronic lymphocytic leukemia (CLL) patients. Methods Patients were treated with different regimen according to Binet stage. Patients at stage A were subcutaneously injected with interferon (3-6) MU/day, consecutive for 5 days every week. The dosage could be reduced to 2-3 times a week in long term maintenance phase after the 6 months loading treatment if there was no disease progression. Those at stage B or C were initially treated with chemotherapy regimen of FC/FC -R or CHOP/COP, and interferon were administered during chemotherapy interval, after complete remission (CR) or partially remission (PR) as maintenance therapy.Results Twenty patients were at stage A and treated with interferon, with 5 patients(25%) achieving partial remission (PR), 14 patients at stable status while no patients acquiring CR. Three of the 5 patients who achieved PR collapsed after 36.3 months at average. Eight of the 14 patients at stable status deteriorated to stage B and received chemotherapy after mean 74 months interferon maintenance treatment. In total, 27 patients in the current observation were finally included at stage B or C. Patients at stage B or C in FC/FC-R chemotherapy regimen achieved CR at 38.9% and total effective rate 77.8%, which were superior to that of CHOP/COP prescription (CR 11.1 %). The mean survival time for patients at stage A, B and C were 155.2,97.5 and 82.9 months, respectively and were statistically significant via Kaplan-Meier analysis method (P =0.032). Ten patients died in this observation, 2 at stage A, 4 at stage B and C, respectively, among whom 9died of infection and 1 for gastric cancer bleeding. The side effects of interferon were generally mild during the long term treatment. Conclusion Patients with CLL need to be individually treated with different regimen by considering disease stage and other prognosis criteria. Interferon could be applied at early phase of CLL and may reduce occurrence of infection after long term treatment.
