OBJECTIVE:To establish a method for simultaneous determination of notoginsenoside R1,ginsenoside Rg1 and gin-senoside Rb1 in Shenqi xinshu capsule. METHODS:HPLC was performed on the column of Zorbax SB-C18(150 × 4.6 mm,5 μm) with mobile phase of acetonitrile-water at a flow rate of 1.0 ml/min,detection wavelength was 203 nm,column temperature was 30℃,and the injection volume was 10 μl. RESULTS:The linear range was 0.199 8-3.996 0 μg for notoginsenoside R1,0.842 8-10.143 0 μg for ginsenoside Rg1 and 0.823 4-9.978 0 μg for ginsenoside Rb1;RSDs of precision,stability and reproducibility tests were low-er than 2%;recoveries were 95.17%-100.17%(RSD=1.81%,n=9),97.32%-101.18%(RSD=1.44%,n=9)and 95.22%-98.89%(RSD=1.22%,n=9). CONCLUSIONS:The method is simple,accurate and reproducible,and can be used for the simultaneous contents determination of notoginsenoside R1,ginsenoside Rg1 and ginsenoside Rb1 in Shenqi xinshu capsule.

Objective To establish a multiplex polymerase chain reaction (PCR) method for rapid detection of three kinds of di‐arrheagenic Escherichia coli(EPEC ,EIEC ,EHEC)simultaneously .Methods The eae gene of EPEC ,ipaH gene of EIEC and stx1 gene of EHEC were selected to design primers ;the reaction system and condition were adjusted to optimize the multiplex PCR sys‐tem .Results The target gene fragments were amplified correctly with these primers .The three target bacteria could be detected at the same time by multiplex PCR .Conclusion A rapid multiplex PCR system were successfully established for detection of three di‐arrheagenic Escherichia coli ,and this system could be suitable for rapid screening in food safety .

Objective To evaluate the therapeutic effect of lentinan combined with conventional antituberculous therapy in women with pelvic tuberculosis.Methods A total of 90 women with pelvic tuberculosis were enrolled and recruited into a control group and a treatment group by random number table,45 in each group.The control group was treated with anti-tuberculosis program (2HRZE/4HRE),while the treatment group was treated with lentinan tablets on the basis of the control group.Both groups were treated for 6 months.Serum levels of carbohydrate antigen 125 (CA125) and erythrocyte sedimentation rates (ESRs) were determined before and after treatment,and the therapeutic effect was evaluated.Results After treatment,the serum CA125 level (28.61 ± 9.08 U/ml vs.39.72 ± 12.13 U/ml;t=4.919,P＜0.01) and the ESR (36.13 ± 8.33 mm/h vs.41.35 ± 12.45 mm/h;t=2.338,P＜0.05) in the treatment group were significantly lower than those in the control group.The negative rate of serum CA125 after treatment than before treatment in the treatment group (93.3％ vs.20.0％;X2=46.335,P＜0.01) and the control group (82.2％ vs.8.9％;X2=37.396,P＜0.01);but there was no difference in negative rate of serum CA125 after treatment between two groups (X2=1.6571,P=0.198).The total effective rate in the treatment group was significantly higher than that in the control group (93.3％ vs.77.8％;X2=4.406,P=0.036).Conclusion Lentinan combined with conventional antituberculous therapy is effective in treatment of pelvic tuberculosis in women.

HLA-G belongs to non-classical HLA-class Ⅰ genes.It is expressed in the fetal-maternal interface on the extravillous cytotrophoblast and in such immune privilege tissues as the cornea and pancreas.However, under pathological conditions, such as tumor, inflammatory diseases and post transplantation, HLA-G is expressed abnormally.HLA-G can interact with its acceptors or immune cells and suppress the function of immune cells, which facilitates the escape of the surveillance of the human immune system and the consequent damage.In clinical studies,HLA-G is related to some clinical parameters.This review will focus on the expression, function and regulatory mechanisms of HLA-G in cancer immunology.

Objective To study the clinical and X-ray findings of primary reticulocytic sarcoma of bone in order to improve its diagnosis and differential diagnosis.Methods X-ray representations of primary reticulocytic sarcoma of bone in 11 cases proved by operations and pathologies in combination with clinical manifestations were analyzed.Results The tumors located in tubular bone were 5 cases(45%),in vertebra,in costa and pelvis were 2 cases respectively.The main X-ray sign was osteolytic lesion.The soft tissue masses were seen in 7 cases and pathologic fracture in 1 case,only 2 cases appeared lightly periosteal reaction.Conclusion When the osteolytic lesions in company with soft tissue mass are showed on X-ray films,but the clinical symptoms of the disease are not as serious as those of other malignant bone tumors,the bone reticulocytic sarcoma should be considered,and the final diagnosis of the disease desponds on pathologic result.

OBJECTIVE To investigate the distribution and resistance of non-fermenting bacteria isolated from our hospital and offer the basis for the treatment of bacterial infection.METHODS Totally 2177 strains of non-fermenting bacteria were isolated from clinical sputum samples between Jan 2006 and Dec 2008.All of the isolated bacteria were identified with API identified test(API Inc,France) and Kirby-Bauer(K-B) test used for the antibiotics susceptive test.RESULTS From them the most common bacteria were Pseudomonas auruginosa(34.9%),followed by Acinetobacter baumannii(28.4%) and Stenotrophomonas maltophilia(11.4%).These bacteria had various resistances to the tested antibiotics.CONCLUSIONS Non-fermenting bacteria have high isolate rate and multi-antibiotic resistance,so antibiotics should be correctly used under the guidance of antibiotic susceptibility test.
