In order to investigate the mutation of HBV polymerase gene reverse transcription conserved region (P region) in chronic hepatitis B (CHB) patients, 212 CHB patients who took antiretroviral treatment with nucleotide analogues were chosen. The drug resistance mutations of HBV P region and HBV genotype were detected by Pyrosequencing. Sequence analysis showed that the drug resistance sites of HBV P region located at sites 173; 180; 181; 184; 204; 236 and 250. The main site of HBV P region drug resistance was 204 and 180, accounting for 35.8% and 23.5%, respectively. There were significant differences in the mutation rate of site 180 among different age groups. There were also significant differences in the mutation rate of site 204 among younger than 30 age group, 41 to 50 age group and 51 to 60 age group. (P < 0.05, P < 0.01). The mutation rate of site 180 combined with site 204 was 66.6%. The mutation rate of site 181 combined with site 236 was 23.3%. The age of C genotype infected patients was significantly older than B genotype infected patients (P < 0.01). M204V/I mutation mostly existed in the form of joint L180M mutation, the mutation rate was age-related. The detection of HBV genotypes and drug resistance sites of HBV P region have important clinical implications for the treatment and prognosis of patients with CHB.

Objective To evaluate the application efficacy of responsibility system for holistic nursing system in high-quality nursing service in the department of respiratory medicine.Methods Department of respiratory medicine unit which was the quality nursing service demonstrated unit in our hospital was selected.The nursing responsibility-bound grouping system was first performed and the nurse-incharge would provide the patients with whole and continuous nursing service.Before and 6 months after the application,the nursing job satisfaction was conducted and the nursing grouping system satisfaction was also evaluated among nurses and doctors.Results Six months after the application of nursing responsibility-bound grouping system,the patient satisfaction with nursing job was raised obviously in the unit.Conclusions The application of responsibility-bound grouping system can not only promote the activity but also mobilize the enthusiasm of nurses,and then high-quality nursing service was resulted.So the service system was worthy of clinical application.

Objective To investigate the roles of aberrant expression of c-myc,c-myb,and c-erbB-2 in the development of breast cancer and its clinical significance.Methods Immunohistochimical technique (S-P method)was used to detect the expression of c-myb,c-myc and c-erbB-2 protein in 150 cases of breast cancer and 30 cases of benign proliferative lesions.heir relation to clinical pathological parameters were analyzed.Results The protein expression levels of c-myc,c-myb,and c-erbB-2 in breast cancer were higher than those in benign proliferative lesions and the difference was significant(all P ＜0.05).Expression of c-myc protein had obvious relationship to histological grade,lymph nodes metastasis and pathological types(all P ＜ 0.05).Expression of c-myb protein related significantly to histological grade (P ＜ 0.05).c-erbB-2 was associated with the tumor size,grading,PR expression (all P ＜ 0.05).The association among the three kinds of genetic proteins was observed.Conclusion Expressions of oncogenes c-myc,c-myb,and c-erbB-2 proteins are higher in breast cancer and lower in benign proliferative lesions.The difference is significant.They are related to the grading and some other prognostic factors such as tumor size,pathologic types,PR expression and lymph node metastasis.The results suggest that these oncogenes are activated in the development of breast cancer and provoke cancerous cells multiplication.Expressions of oncogenes c-myc,c-myb and c-erbB-2 mightbe considered to be the prognostic indicators of breast cancer.

As a functional imaging method, positron emission tomography (PET) is widely used in tumor diagnosis, pathological classification, stage assessment, and clinical outcome evaluation. Combination of metabolic information acquired from ~(18)F-fluorodeoxyglucose (~(18)F-FDG) PET with pathological grading results is helpful for further defining the grade of sarcomas and predicting prognosis. ~(18)F-FDG PET appears to be superior to other imaging modalities in detecting bone metastases or pulmonary metastases of sarcoma patients, so it could be used in clinical staging and restaging of sarcoma. Tumor-to-background ratio (TBR) and standardized uptake value (SUV) are two important parameters for quantitative analysis and are helpful for assessing chemotherapy response of tumor. PET imaging offers important information to help maximize the clinical benefit of patients with sarcoma. This article reviews the clinical value of ~(18)F-FDG PET and ~(18)F-FDG PET/CT in diagnosis of sarcoma.

OBJECTIVE　A HPLC method was established for the determination of racecadotril and its impurities.METHODS　A ODS column was used and the mixture of acetonitrile-potassium dihydrogen phosphate (KH2PO4) solution (70∶30) was used as the mobile phase.The detection wavelength was 210 nm.RESULTS　The liner range of the racecadotril was 0.08～0.24 mg*mL-1 and the regression equation was Y=15847X+3873(r=0.9997).The liner range of benzylthiorphan disulphide was 2.40～21.56 μg*mL-1 and the regression equation was Y=1826x+46 (r=0.9999).The measurable lowest limit was 1 μg*mL-1.The average recovery was 100.0%.CONCLUSION　The method was convenient,accurate and specific.

Objective To observe the curative effect and safety of Xiaoer zhixie decoction in treatment children with infectious diarrhea.Methods 84 cases with infectious diarrhea were randomly divided into 3 groups (positive control group,Xiaoer zhixie decoction group and control group).The control group (n =27) was treated with conventional therapy such as nutritional therapy.The Xiaoer zhixie decoction group (n =28) was given Xiaoer zhixie decoction through clysis.Positive control group(n =29) was treated with oral.Smectite powder.The therapeutic effect of 3 groups was observed during the 3rd day,the 5th day and the 7th day after treatment.Results The total effective rate of control group was 40.7％,positive control group was 79.3％ and Xiaoer zhixie decoction group was 78.6％ after 3 days treatment.Compared with control group,positive control group and Xiaoer zhixie decoction group achieved obvious effect(P ＜0.01).The positive control group and Xiaoer zhixie decoction group did not have significant difference(P ＞0.05).Conclusion The clinical effect of Xiaoer zhixie decoction in treatment children with infectious diarrhea is significant.

ObjectiveTo detect the expression of ARHI protein in adenocarcinoma of the uterine cervix and normal uterine cervix tissue, and explore the pathogenesis of cervical cancer. MethodsThe expression of ARHI protein in 30 cases of adenocarcinoma of the uterine cervix tissue and 30 cases of normal uterine cervix tissue was detected by immunohistochemistry and analyzed the relationship between ARHI protein and adenocarcinoma of the uterine cervix. ResultsThe expression of ARHI protein in adenocarcinoma of the uterine cervix tissue[46.67％(14/30)]was lower than that in normal uterine cervix tissue[90.00％(27/30)],the difference was significant (P＜0.05). There was intimate correlation between ARHI protein and histological grade, FIGO stage of adenocarcinoma of the uterine cervix tissue (P ＜ 0.05), there was no correlation between ARHI protein and lymphatic metastasis (P＞0.05). ConclusionsThe expression of ARHI protein in adenooarcinoma of the uterine cervix decreases which indicates the expression of ARHI protein take part in the carcinogenesis of adenocarcinoma of the uterine cervix. It can be used as a new diagnostic indicator of adenocarcinoma of the uterine cervix.
