[Objective] Domestic literatures on misdiagnosis of osteonecrosis of femoral head(OFH)in the past 15 years are reviewed to distinguish OFH from other 9 similar diseases.The symptoms in early,middle and late stages of OFH are similar to other diseases,which is easy to be misdiagnosed as OFH.Pathological changes in different hip joint diseases have different specific performances.Careful and discriminative diagnosis is important in clinical practice.

Objective The study aims to assess the health education effects of popular scientific brochure with pictures on infant vulvovaginitis. Methods Parents of female child outpatients aged 0～5 years old with vulvovaginitis of our hospital were selected for health education, mainly about how to prevent vulvovaginitis. Popular scientific brochure with pictures was designed for use. Eighty six parents of female child patients aged 0～5 with vulvovaginitis were randomly divided into the control group and the observation group with 43 people in each group. In the control group, health brochures were issued and face-to-face guidance were carried out. In the observation group, popular scientific brochures with pictures were issued and faceto-face guidance were carried out Phone call investigations were done 4-8 weeks after issuing of education materials. Results Awareness rate, vulvovaginitis cure rate of their female child and satisfaction rate to education method of the observation group were significantly higher than the control group. Conclusions Health education guidance in form of popular scientific brochure with pictures can get more satisfactory effects.

Objective To evaluate the therapeutic efficacy and toxicity of oxaliplatin (OXA)-based systemic chemotherapy in patients with advanced hepatocellular carcinoma (HCC).Methods Thirty patients with advanced HCC admitted to our hospital from June 2009 to June 2013 were randomly divided into CapeOX group (15 patients,treated with OXA and capecitabine or CAP)and FOLFOX group (15 pa-tients,treated with OXA and calcium folinate or CF,followed by fluorouracil or 5 -FU).The therapeutic effects were evaluated after two cycles of treatment using the Response Evaluation Criteria in Solid Tumors (RECIST 1 .1 ).Assessment criteria included overall response rate (OR),time to tumor progression (TTP),and overall survival (OS)analyzed by Kaplan-Meier survival curves,as well as the toxicity profile of the combination chemotherapy.Comparison of OR was made by chi-square test;assessment of tumor response and toxicity profile was performed by Mann-Whitney U test;OS and TTP were analyzed by log -rank test.Results In the CapeOX group,the OR was 13.3%,and the mean OS and TTP were 10.4 months and 5.0 months,respectively.In the FOLFOX group,the OR was 6.7%,and the mean OS and TTP were 9.0 months and 4.7 months,respectively.The differences between the two groups had no statistical significance in all three parameters (P=0.543,0.606,and 0.769,respectively).Compared with the FOLFOX group,the CapeOX group had significant-ly lower toxicity rates in gastrointestinal tract and myelosuppression (P=0.006 and 0.002,respectively).Conclusions The OXA-based systemic chemotherapy shows anti-tumor effects for advanced HCC,and there is no significant difference in efficacy between the two regi-mens.Decisions regarding the choice of specific treatment should be based on the patients'clinical conditions.

Objective To investigate the factors that influence the patients to understand the stroke they suffering from.Methods 61 stroke patients were investigated with a questionnaire designed by ourselves.ResultsThe age,sex and educated level affected the stroke patients' understanding,but the time after onset,the degree of locomotory injured and hemiplegic side did not.ConclusionDistinguishing direction of rehabilitation should be established according to the age,sex and educated level of patients.

Tissue microarray is a special biologic microarray, which was invented on the base of cDNA microarray. The principle of the tissue microarray is arraying the tissue on the solid carrier according demand, then hybridizing, marking and dyeing, for researching the special expression of aimed gene or production among the different tissue. The application of tissue microarray is abroad, especially the determinant of tumor predisposing factor, the screening of the special gene and antibody, the earlier diagnosis, the therapy, and the judgment of prognosis. Compared with the traditional pathological investigation, tissue microarray has the behavior of small volume, high throughput (information), and design by different demand. Tissue microarray has important practical significance and broad market prospect in the investigation of the relation between the gene and disease (tumor), the verification of the associated gene of the disease, the development and screening of new drug, the molecular diagnosis of disease, the dynamic observation during therapy, and the judgment of prognosis.

Objective To investigate the effects of benazepril on urinary excretion of endothelin 1(Et 1) and the level of plasmic Et 1 (PEt) in patients with diabetes mellitus (DM) and diabetic nephropathy(DN).Methods PEt and 24 hours urinary excretion of Et 1 (UEtV) in 54 patients with DM and 39 patients with DN before and after taking benazepril (7.5～12.5mg/d) for two months were measured using radioimmunoassay method.Results PEt and UEtV in patients with DM were significantly higher than in normal control group ( P

0.05).Conclusion The reduction of neoronal proliferation in dentate gyrus may be responsible for the damage of learning and memory ability in aged rats.

Objective To explore the causes and treatment measures of hyponatremia after liver transplantation. Methods The clinical data of 27 patients with hyponatremia after liver transplantation were analyzed retrospectively. Results Among the 27 patients, postoperative hyponatremia occurred in 25 cases in about one week, and preoperative hyponatremia occurred in 2 cases and severe ~hyponatre -mia occurred immediate after operation. Acute hyponatremia occurred in one case. Blood natrium was 130 to 135 mmol/L in 10 cases, 120 to 130 mmol/L in 12 cases and less than 120 mmol/L in 5 cases. The levels of blood potassium, phosphor and calcium were all normal. Urinary natrium, potassium and chlorine levels were all normal. The ascites natrium level was higher than blood natrium at the same time. Hyponatremia was treated by supply of hypertonic saline via gastrointestine an/or veins. Conclusion Various causes could result in hyponatremia after liver transplantation. The hyponatremia was treated by supply of hypertonic saline constantly and slowly.

Objective To investigate tile clinical significance of IL-13 gene expression in peripheral blood mononuclear cell(PBMC) and level of plasma IL-13 from patients with lupus nephritis(LN). Methods Ten healthy volunteers and 16 patients with LN were included in this study. All patients had been performed percutaneous renal biopsy and examined by light and immunofluorescence microscopy. The expression of IL-13 nRNA in PBMC was evaluated by RT-PCR. The level of plasma IL-13 was determined using an IL-13 specific ELISA. Results The expression of IL-13 mRNA in PBMC and the levels of Plasma IL-13 from patients with LN were significantly higher than those of the controls(l .99 ? 0.29 vs 0.68 ? 0. 15, P

Objective:To study whether caspase-6 was activated during resveratrol(Res)- induced apoptosis of nasopharyngeal carcinoma cells CNE-2Z. Methods:The cleavage of pro-caspase-6 was analyzed by Western-blot. TTie changes of caspase-6 mKNA was detected by semi-quantitative RT-PCR. The changes of caspase-6 activity was determined by colorimetric assay. Results: After CNE-2Z cells were treated with 0 (control), 25, 50, 100, 200 pmol/L Res for 24 h, respectively, the expression of pro-caspase-6 was decreased with concentration increasing. Caspase-6 active fragment P20(20 kD) appeared at 100 fjtmol/L and was increased at 200 (junol/L.The expression of caspase-6 mR-NA was increased in a concentration-dependent manner ( P
