Objective To observe the virology response after the treatment of chronic hepatitis C by polyethylene glycol interferon in combination with ribavirin and the etiological characteristics of chronic hepatitis C.Methods A retrospective analysis of chronic hepatitis C infection route,hepatitis C virus(of hepatitis C virus,HCV)load and its gene typing of 120 patients in our hospital from August 2009 to July 2012.And the patients were given pegylated interferon (PEG-IFN-2a),or ordinary interferon (IFNα) alone or in combination with ribavifin.HCV-RNA load and liver function were monitored before and after 4,12,24,36,48 weeks.Results Blood transfusion was the main way of HCV infection(71/120).109 cases (90.8％) patients with serum HCV-RNA load between 5.0 ～ 7.0 logl0 copies/ml.76 patients were made HCV viral genetics testing,test results,65 cases of HCV-RNA 1b type,2 cases of HCV-RNA 1c type,HCV-RNA 2a type and HCV-RNA 6a type and HCV-RNA type 3b was 3 cases,especially.The application of PEG-IFN-2a of the two groups was significantly better than the application of IFNα of the two groups(P ＜ 0.05).Conclusion Chronic hepatitis C is mainly to infected by blood transfusion.HCV-RNA load between 5.0 ～ 7.0 log10 copies/ml.88.2％ of the cases of genotype 1(most of which is type 1b).PEG-IFN-2a combined with ribavirin combined with individualized treatment can effectively improve SVR rates.

Objective To compare the rutin contents in 7 kinds of commercial Fructus jujubae by HPLC method. Methods The analysis was carried on MN NUCLEODUR C18 column. The mobile phase consisted of acetonitrile-0.05 % H3PO4(15 ∶ 85), flow rate was 1.0 mL/min, determination wavelength was 257 nm and the column temperature was at 40 ℃ . Results The linear range was 0.050 5～ 0.404 4 ? g and r= 0.998 7.The recovery was 96.2 % and RSD 1.6 % (n=6). Conclusion This method can eliminate the interference of sugar ingredients efficiently and is with good repeatability. It is suggested that the plumper the fruits of jujubae, the higher the content of rutin.

Different from fasting blood glucose reflecting the basal glucose level of the body, the post-prandial blood glucose gives us the information about the highest glucose level during a day. It has been proved that post-prandial hyperglycemia (PPG) is associated with cardiovascular diseases more closely, which may be caused by oxidative stress, hence the management of PPG is of great meanings. But what is the effect of PPG control on the treat-to-target blood glucose management? This is a question worth discussing.

MicroRNAs (miRNAs) are a class of non coding small RNAs. MiRNAs can regulate cell signal transduction and gene expression, affect cell proliferation, apoptosis and other cell physiological processes, and play a crucial role in maintaining normal biological metabolism and homeostasis of the intracellular environment. In addition, miRNAs are widely involved in the occurrence and progress of cancer. Studies have shown that miRNA27a, a member of the miRNAs family, can play the role of oncogene or tumor suppressor gene in different cancer disease models. This article will review the expression, mechanism and potential clinical application of miRNA27a in different malignant tumors.

Objective To explore the causes of congenital hypothyroidism by single photon emission computed tomography(SPECT) thyroid imaging.Methods Nineteen cases with congenital hypothyroidism were collected,and SPECT thyroid imaging was performed 15 minutes late after injected 99m TcO_ 4- 18.5-37.0 MBq.Results Five cases were found with normal glands,1 case with enlarged thyroid, 2 cases with enlarged thyroid and increased radiation,4 cases with ectopic thyroid,4 with a hypogenetic thyroid,and the last 3 cases showed no thyroid imaging.Conclusions The causes of congenital hypothyroidism can be found by SPECT thyroid imaging,which is important to the diagnosis of congenital hypothyroidism combined with detection of T_3,T_4,TSH.

Objective: To make a preliminary prediction of the Q-marker of Glycyrrhizae Radix et Rhizoma from the perspective of the effectiveness and measurability of chemical components based on the concept of Q-marker of Chinese materia medica. Methods: Based on literature integration and data analysis, the source range of Glycyrrhizae Radix et Rhizoma Q-marker was screened, and the effectiveness of the ingredients was analyzed through network pharmacology. Qualitative and quantitative analysis of 15 batches of Glycyrrhizae Radix et Rhizoma from four places of origin was performed by HPLC. The pattern recognition method was used to screen out the main marker components that caused the differences between groups, which were combined with network pharmacological results to further determine the Q-marker of Glycyrrhizae Radix et Rhizoma. Results: Literature studies had determined that flavonoids and triterpenoids were the main source of Glycyrrhizae Radix et Rhizoma Q-marker; Network pharmacology results showed that liquiritin, glycyrrhizic acid and other components had high connectivity in the "component-target-pathway" network and were the main active components; The fingerprints of 15 batches of Glycyrrhizae Radix et Rhizoma samples were established, and five components, including liquiritin and liquiritin apioside, were identified as the main marker components by PLS-DA analysis; The content determination results of liquiritin, liquiritin apioside, glycyrrhizic acid and glycyrrhetinic acid showed that there were significant differences in the content of ingredients among different production areas. The qualitative and quantitative research on pharmacology combined with network pharmacology revealed that liquiritin, liquiritin apioside, glycyrrhizic acid and glycyrrhetinic acid can be used as Glycyrrhizae Radix et Rhizoma Q-marker. Conclusion: Taking flavonoids and triterpenoids as the source of Q-marker for Glycyrrhizae Radix et Rhizoma, the qualitative and quantitative (measurability) study of Glycyrrhizae Radix et Rhizoma herbs from multiple producing areas combined with network pharmacology (effectiveness) revealed liquiritin, liquiritin apioside, glycyrrhizic acid and glycyrrhetinic acid as the potential Q-marker of Glycyrrhizae Radix et Rhizoma are scientific and reasonable, which provide reference for quality control of Glycyrrhizae Radix et Rhizoma.

Objective To evaluate the roles of B-type natriuretic peptide (BNP) in predicting the severity of community-acquired pneumonia (CAP) by studying the correlation between them.Methods A total of 202 patients with CAP admitted from December 2011 to December 2012 were enrolled in this study.All these patients were checked with laboratory tests for BNP level,C-reactive protein (CRP),white blood cell count (WBC) as well as other markers needed for obtaining pneumonia severity index (PSI).The differences in BNP levels,CRP levels,and WBC were compared among different degrees of pneumonia severity,and the correlation between BNP levels and PSI was investigated by a linear correlation analysis.The patients enrolled were divided into a high-risk group (defined as Ⅳ-Ⅴ grade of PSI) and a low-risk group (defined as Ⅰ-Ⅲgrade of PSI).Meanwhile,they were also divided into a survivor group and a non-survivor group according to outcomes.BNP levels between the two groups were compared,and a receiver operating characteristic (ROC) curve analysis was performed on the BNP levels versus PSI.Results BNP levels increased with CAP severity (r =0.782,P ＜0.01).The mean level of BNP (263.2 ± 119.6) pg/mLof patients in the high-risk group was significantly higher than that of patients (71.5 ± 54.3) pg/mL in the low-risk group (P ＜ 0.01).The patients in the non-survivor group had significantly higher BNP levels compared to the survivor group [(343.86 ± 125.49) vs.(183.00 ±121.71) pg/mL,P ＜ 0.01].In addition,there were positive correlations between BNP levels and PSI (r =0.782,P＜0.001),between BNP levels and CRP levels (r =0.560,P＜0.01),and between BNP levels and WBC (r =0.513,P＜0.001).The BNP level had a high accuracy in predicting the severity of CAP (AUC =0.952).The optimal cut-off point of BNP level for distinguishing high-risk from low-risk patients was 125.0 pg/mL,with a semitivity of 0.891 and a specificity of 0.946.Moreover,BNP level had a definite accuracy in predicting mortality (AUC =0.823).Its optimal cut-off point for predicting death was 299.0 pg/mL,with a sensitivity of 0.675 and a specificity of 0.816; its negative predictive cut-off value was 0.926,and positive predictive value was 0.426.Conclusions BNP level is positively correlated with the severity of CAP.The patient with BNP level above 125.0 pg/mL should be hospitalized immediately and patients with BNP level higher than 299.0 pg/mL are at the high risk of death.Therefore,BNP is a useful biomarker for evaluating the severity of patients with CAP.
