[Objective] To sum up teacher He Lingzhi’s clinical experience and academic ideas on diagnosing and treating IgA nephrosis. [Method] From casa morbi, mechanism and clinical treatment based on differentiation of signs, it expounds teacher He Lingzhi ’s clinical experience and academic points, exampled with a case. [Result] The disease has main mechanism of Qi deficiency, teacher He Lingzhi divides the IgA nephrosis into types of Qi deficiency of lung and spleen, spleen and kidney, both deficiency of lung and kidney, Yang deficiency of spleen and kidney, Yin deficiency of liver and kidney, both deficiency of Qi and Yin, Yin and Yang, thus forms the treating rules of tonifying Qi to reinforce spleen, tonifying lung to nourish kidney, tonifying liver and kidney, Qi and Yin, Yin and Yang. The case here was relieved the nephrosis symptoms with the treatment. [Conclusion] Teacher He Lingzhi has rich clinical experience in treating IgA nephrosis with differentiation of signs, with definite cure effect.

Objective To explore the relationship of human papilloma virus (HPV) genotype and loading dose with development of cervical intraepithelial neoplasia (CIN) or squamous cell carcinoma of the cervix ( SCC),and explore the relationship of HPV genotype and CIN or SCC.Methods One hundred and twenty four patients in Sun Yat-sen Memoral Hospital of Sun Yat-sen University with CIN or SCC from September 2005 to December 2010 were selected in this study.HPV DNA was detected by Hybrid capture Ⅱand flow-through hybridization and gene chip.The relationship between the infection of HPV and CIN or SCC was analyzed.The influencing factors of CIN or SCC were analyzed by logistic regression.Results The total detection rate of HPV was 75.8％,and it was 44.4％,70.0％,95.7％ and 76.2％ in CIN Ⅰ,CIN Ⅱ,CIN Ⅲ and SCC group,respectively.The detection rate of HPV in high-grade lesion group ( 84.5％ ) was higher than low-grade lesion group(44.4％ ).The median of HPV load decreased in order as CIN Ⅲ,SCC,CIN Ⅱ and CIN Ⅰgroup.Infection of multi-genotypes or single genotype of high-risk HPV accounted for 97.9％.In logistic regression,HPV loading dose had significant influence on degree of cervical lesion.Conclusions Infection of HPV is a main etiological factor for SCC.There is some kind of correlation between HPV loading dose and development of SCC.

Acetabulum fracture, the inner fracture of the joint, has be en divided into 10 kinds. Because acetabulum is an irregular body, no single ope ration approach can solve all kinds of acetabular fracture. Appropriate selectio n of the operative approach according to the type of fracture is very important. Kocher-Langenbeck approach, extended-iliofemoral approach and ilioinguinal ap proach are often used in clinic now. Because of its complicated procedures and m any complications resulting from the approach, the application of extended-ilio femoral approach is decreasing. Because of its predominant advantage and improve ment of the operation techniques, the use of ilioinguinal approach is obviously increasing in proportion. Since the united approach can reveal clearly so that i t facilitates reduction and internal fixation, it is recommended by the surgeons at home and abroad.

Objective To investigate the correlation between serum homocysteine(Hcy) ,folic Acid ,vitamin B12 ,ferritin levels and cerebral infarction ,and provide a new way for prevention and treatment of cerebral infarction .Methods Forty -eight hospital‐ized patients with ischemic cerebrovascular disease who were in the neurology ward department of the hospital from April 2012 to November 2014 were enrolled in the study as cerebral infarction group .Meanwhile ,30 healthy elderly patients were recruited ran‐domly as a healthy control group during the same period .There was no significant difference in sex and age between the two groups .People with other diseases were excluded .Hospitalized patients were diagnosed within 24 -72 hours and received CT and MRI scan and other related auxiliary examination after being admitted to hospital .All these patients underwent plasma Hcy ,folic acid ,vitamin B12 ,ferritin level tests which were determined by using chemiluminescence and radioimmunoassay .SPSS17 .0 statistical software was used for statistical analysis ,and the correlation between Hcy ,folic acid ,vitamin B12 ,ferritin and cerebral infarction were analyzed .Results The plasma Hcy and ferritin levels in cerebral infarction group were higher than those in control group ,and the difference is significant(P<0 .05) .Meanwhile ,folic acid ,vitamin B12 levels in cerebral infarction group were lower than those in control group and the difference was significant(P<0 .05) .There were significant differences in levels of Hcy ,folic acid ,vitamin B12 ,ferritin between groups of different cerebral infarction levels .Conclusion Detections of serum Hcy ,folic acid ,vitamin B12 and ferritin could be of important clinical value in cerebral infarction .

Objective To establish neoplasm transplantation models of breast cancer cells in BALB /c nude mice and to isolate tumor infiltrating myeloid cells.Methods pHAGE-EF-ZsG-DEST plasmid,pMD2.G plasmid and psPAX2 were transfected into BT474 using the method of calcium phosphate transfection .The positive cells were selected by flow cytometry and implanted in the fat pad of nude mice .A tumor model of breast cancer cells implanted in nude mice was constructed, and the tumor infiltrating myeloid cells were isolated .Conclusion Tumor infiltrating myeloid cells are successfully isolated, which will contribute to the study of the functions of tumor infiltrating myeloid cells .

Objective To observe the change rules of expressions of IL-1β, IL-4, IFN-γ and TGF-β1 in serum and colon tissue in rats with ulcerative colitis of spleen-kidney yang deficiency type; To explore the action in the progress of ulcerative colitis of spleen-kidney yang deficiency type.MethodsComposite method was used to establish rat models with ulcerative colitis of spleen-kidney yang deficiency type. 75 Wistar rats were randomly divided into blank group, model 3 d group, model 7 d group and model 21 d group. ELISA was used to test the levels of IL-1β, IL-4, IFN-γ and TGF-β1 in serum and colon tissue.Results Compared with the blank group, contents of IL-1β and IFN-γ in model group increased significantly (P<0.05,P<0.01), and the contents of IL-4 and TGF-β1 content decreased (P<0.05,P<0.01),especially in the model 7 d group (P<0.01).ConclusionThe pro-inflammatory factor IL-1β, IFN-γ and anti-inflammatory factor IL-4 and TGF-β1 play an important role in rats with ulcerative colitis of spleen-kidney yang deficiency type.

OBJECTIVE:To compare the curative effect of domestic cefoperazone/sulbactam and imported one for lower respiratory infection. METHODS:The curative effects of domestice vs. imported cefoperazone/sulbactam in 201 vs. 198 patients with lower respiratory infection in recent two years in our hospital were analyzed retrospectively. RESULTS:The effective rate was 61.6% for imported product and 51.7% for domestic product. Significant difference was noted between 2 groups statistically(P

Abstract: Fifteen novel ligustrazine-tetrahydroisoquinoline derivatives were designed and synthesized according to the association principle of pharmaceutical chemistry. The structures were identified by IR, NMR and ESI-MS. The inhibitory activities of platelet aggregation induced by ADP and AA have been measured by Bron method. Preliminary pharmacological results showed that compounds 7g, 7h and 7n had potent inhibitory activity against platelet aggregation induced by AA, and the compound 7o showed significant inhibitory activity against platelet aggregation induced by ADP.
