Objective:To evaluate the reliability and validity of the Chinese version of concise health status questionnaire (SF-36 scale) in evaluating the quality of life of patients with chronic Keshan disease, and to provide a scientific basis for studying the quality of life and the evaluation of treatment and rehabilitation of this population.Methods:In the August 2017, using cluster random sampling method, 175 patients with chronic Keshan disease treated by self-management of family beds in Pingliang City, Gansu Province in 2017 were selected as survey subjects, and demographic and disease data were collected. The Chinese version of SF-36 scale was used to investigate the quality of life. Split-half reliability and Cronbach's α coefficient were used to evaluate the reliability of the SF-36 scale; the factor analysis, correlation and differences between groups were used to evaluate the validity of the SF-36 scale.Results:The split-half reliability value of SF-36 scale was 0.916, and the Cronbach's α coefficient was 0.869. Factor analysis extracted 3 common factors from 8 dimensions of SF-36 scale, and the cumulative contribution rate of the 3 common factors to the total variance was 72.08%. In addition to the correlation coefficient ( r) between Role-Emotional and Bodily Pain dimension, the r value between total score and the scores of each dimension, and the scores of each dimension of SF-36 scale were 0.140 - 0.769. Except for the Bodily Pain dimension, there were statistically significant differences in the scores of Physiological Functioning, Role-Physical, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health dimension of the quality of life of patients with different grades of cardiac function ( F = 4.66, 10.73, 6.77, 14.61, 5.58, 9.57, 7.10, P < 0.05). Conclusion:The Chinese version of SF-36 scale has good reliability and validity in evaluating the quality of life of patients with chronic Keshan disease, and can be used to evaluate the quality of life of the patients.

Ossifying fibroma (OF) and fibrous dysplasia (FD) are two fibro-osseous lesions with overlapping clinicopathological features, making diagnosis challenging. In this study, we applied a whole-genome shallow sequencing approach to facilitate differential diagnosis via precise profiling of copy number alterations (CNAs) using minute amounts of DNA extracted from morphologically correlated microdissected tissue samples. Freshly frozen tissue specimens from OF (n = 29) and FD (n = 28) patients were obtained for analysis. Lesion fibrous tissues and surrounding normal tissues were obtained by laser capture microdissection (LCM), with ~30-50 cells (5 000-10 000 µm

Objective: To investigate the clinical effect and safety of entecavir (ETV) versus tenofovir disoproxil fumarate (TDF) in the treatment of previously untreated HBeAg-positive chronic hepatitis B (CHB) patients with a high viral load. Methods: A retrospective analysis was performed for the clinical data of 152 HBeAg-positive CHB patients with a high viral load (HBV DNA≥10⁶ IU/ml) who were firstly treated with ETV (ETV group) or TDF (TDF group), with 76 patients in each group. The serum levels of alanine aminotransferase (ALT), HBV DNA, HBeAg, anti-HBe, creatinine, and creatine kinase were measured at baseline, and the patients were followed up and evaluated at weeks 4, 12, 24, 36, 48, 60, 72, 84, and 96 of treatment. The Kaplan-Meier survival curves were used to analyze cumulative complete virologic response, HBeAg seroconversion, and ALT normalization rate. The Cox proportional hazards regression model was used to identify the influencing factors for virologic response. P < 0.05 was considered statistically significant. Results: There were no significant differences in ALT normalization rate between the ETV group and the TDF group at weeks 4, 12, 24, 48, 72, and 96 of treatment (18.1%/55.6%/83.3%/90.3%/93.1%/97.2% vs 16.0%/53.6%/75.4%/94.2%/100%/100%, P > 0.05). There were also no significant differences in virologic response rate between the ETV group and the TDF group at weeks 48 and 96 of treatment (89.5%/97.3% vs 93.4%/98.7%, P > 0.05). The multivariate analysis showed that the baseline parameters were not predictive factors for virologic response. At week 48 of treatment, the TDF group had a significantly higher HBeAg seroconversion rate than the ETV group (14.5% vs 3.9%, P = 0.048); at week 96 of treatment, there was no significant difference in HBeAg seroconversion rate between the two groups (15.8% vs 7.9%, P = 0.132). The Kaplan-Meier survival analysis showed that there were no significant differences between the two groups in cumulative ALT normalization rate, cumulative HBV DNA undetectable rate, and cumulative seroconversion rate. Only one patient in the ETV group experienced virologic breakthrough from weeks 60 to 72 of treatment, and there were no serious adverse reactions. Conclusion TDF and ETV had similar clinical effects, HBeAg seroconversion rate, and safety in previously untreated HBeAg-positive CHB patients with a high viral load.

OBJECTIVETo prepare a monoclonal antibody (mAb) against the fusion protein preM/EIII of West Nile virus (WNV) for clinical detection of WNV.

METHODSSp2/0 cells were fused with the spleen cells of BALB/c mice immunized with the recombinant fusion protein preM/EIII expressed in E. coil to obtain the hybridoma cell line that secreted preM/EIII mAb. The hybridoma cells were injected into the peritoneal cavity of BALB/c mice and the ascites was collected and purified. The specificity and titer of the obtained mAb were determined using ELISA and Western blotting.

RESULTSOne hybridoma cell line secreting preM/EIII mAb, named ME1, was obtained. The titer of the purified mAb was 10(-6). Identified as a mAb of the Ig subclass IgG1, ME1 was capable of specific reactions with preM/EIII protein and WNV without cross-reactions with other viruses such as JEV, SLEV, YFV and DENV. The accuracy of clinical testing of MNV with ME1 was 97.78%.

CONCLUSIONThe mAb against preM/EIII obtained have a high specificity and accuracy in clinical testing of MNV and can be used in clinical diagnosis of MNV infection.

OBJECTIVE: To investigate the maxillary sinus development and provide data for sinus surgery on children. METHOD: Two thousand two hundred and thirty-eight children were randomly selected among those who underwent skull and nasal sinus CT scanning because of certain symptoms and signs. Patients were divided into eighteen age cohorts based on their age at the time of the scan. Anterior-posterior, transverse diameters and vertical height of the maxillary sinus were measured and statistically analyzed. RESULT: The maxillary sinus volume was enlarging even in adult, hut the growth of maxillary sinus was relatively stable in adolescent. The difference of transverse and anterior-posterior diameters of maxillary sinus had no statistical significance between female and male (P > 0.05), while there was statistically significant difference in the vertical height of maxillary sinus (P < 0.05). CONCLUSION The results will aid the physicians when correlating the clinical and radiographic findings of pediatric patients who are being evaluated for sinus disease and potential surgical intervention.

Objective To explore the diagnostic value of GP-/3 protein in gene detection in the patient of primary hepatic carcinoma, to discuss the joint roles of serum GP73 and AFP, and provide a novel method for the diagnosis for PHC and screening for high-risk population. Methods ELISA was used to detect the serum level of GP73 and AFP in 73 cases of PHC, 13 cases of hepatic cirrhosis, 32 cases of hepatitis and 62 cases of health people. SYBR Green real time fluorescence quantitative PCR was used to detect the relative value of GP73 mRNA in the peripheral blood cells of each group. Comparative Ct method was used to evaluate the relative expression levels. Eight cases of normal liver tissues and 8 cases of PHC tissues were detected at the same time to compare the relative expression levels. Results Kruskal-Wallis test showed that the serum levels of GP73 and AFP had significant differences between four groups(H value were 89. 6 and 52.0, P ＜ 0. 01) and the whole blood GP73 mRNA had no significant differences(H =4. 33, P ＞ 0. 05). Mann-Whitney test showed that the serum levels of GP73 had significant differences among PHC groups[166. 7 (162. 7-231.8) μg/L] and liver cirrhosis[57. 3 (46. 6-113. 6) μg/L], hepatitis[29. 6(26. 2-54. 5) μg/L], health group[25.1 (20. 8-29. 4) μg/L] (U value were 246, 297, 349, P ＜ 0. 01).The A FP levels of the four groups were 380. 9 (258.5-503.2) μg/L, 3.8 (1.3-14. 5) μg/L, 5. 1 (2. 4-7. 8)μg/L and 2. 8(2. 2-5.7) μg/L. It also showed significant differences (U value were 246,419 and 790,P ＜0. 01). The GP73 mRNA expression of PHC liver tissues(12. 64) was significant higher than normal liver tissues (1.00). The critical values for GP73 and AFP was determined to be 123. 2 μg/L and 10. 6 μg/L through the 8OC curves. Under the critical value the sensitivity of GP73 and AFP were 65.8% and 53.4% ,and the specificity of CP73 and AFP were 95.3% and 92. 5% respectively. Joint detection could increase the sensitivity up to 79. 5%, and achieve the high specificity of 90. 7%. Conclusions As a new diagnositic marker of primary hepatic carcinoma, GP73 protein has the very good sensitivity and specificity. The GP73 mRNA in the whole blood sample could not be used for the diagnosis of PHC. But it woule be a good molecular marker for diagnosis of PHC in the liver tissue sample. The joint detection of GP73 and AFP could improve PHC diagnostic performance, and provide an effective approcach to the PHC high-risk screening.

OBJECTIVETo investigate the correlation between glutathione S-transferase (GST) M1 and T1 genotypes and endometriosis risk (EM).

METHODSPolymerase chain reaction (PCR) technique was used to detect the presence or absence of the GSTM1 and GSTT1 genes in genomic DNA isolated from the blood samples of 68 Han Chinese women with endometriosis and 28 without endometriosis.

RESULTSThe frequencies of GSTM1 and GSTT1 null genotypes in women with endometriosis were 0.721 (49/68) and 0.779 (53/68), respectively, and in women without endometriosis were 0.429 (12/28) and 0.321 (9/28), respectively. There was a significant difference with regard to the frequencies of GSTM1 and GSTT1 null genotypes between the women with and without endometriosis (P < 0.01). Furthermore, the frequencies of GSTM1 and GSTT1 null genotypes were significantly higher in the patients with stage III and IV endometriosis [0.731 (38/52) and 0.788 (41/52), respectively] than in women without endometriosis (P < 0.01), and the frequency of GSTT1 null genotype was statistically higher in patients with stage I and II endometriosis [0.75 (12/16)] than in the women without endometriosis (P < 0.01). No correlation between GSTM1 and GSTT1 null genotypes and age, induced abortion or dysmenorrhea was detected in this study (P > 0.05).

CONCLUSIONGSTM1 and GSTT1 null genotypes may be risk factors for the development of endometriosis.
