Hepatitis B virus (HBV) infection is an important global public health concern and a major cause of chronic hepatitis, cirrhosis and liver cancer. Many studies have shown that different genotypes and subtypes have significant differences in pathogenicity, thus affecting the disease progression and prognosis of infected individuals. So far, a total of 10 HBV genotypes and more than 40 subtypes have been reported across the world, and these subtypes have shown distinct distribution characteristics. In the present review, we systematically summarized the current situation on the global distribution of HBV genotypes.

Objective To address the mediating role of cognitive emotion regulation in the relationship between parenting styles and health risk behavior in left-behind children.Methods A total of 404 leftbehind children were surveyed with the egna minnen av barndoms uppfostran (EMBU),the cognitive emotion regulation questionnaire-Chinese version (CERQ-C) and the adolescent health related risky behavior inventory (AHRBI).Results (1) The whole average score of AHRBI was (1.47±0.24);the scores of positive and negative cognitive emotion regulation respectively were (10.52±2.56) and (9.51±2.55);the scores of Authoritative,authoritarian and permissive/neglecting parenting styles respectively were (44.06± 8.50),(18.89±3.44) and (10.15±2.32).(2)The health risk behaviors of left-behind children were negatively related with authoritative parenting style (r=-0.26 ～-0.46,P＜0.01) and positive cognitive emotion regulation(r=-0.19～-0.44,P＜0.01),and positively related with authoritarian parenting style,permissive/neglecting parenting styles(r=0.19 ～ 0.40,P＜0.05) and negative cognitive emotion regulation (r=0.25 ～0.51,P＜0.05).(3) Authoritative parenting style was positively related with positive cognitive emotion regulation (r=0.30 ～ 0.47,P＜0.01),and negatively related with negative cognitive emotion regulation (r=-0.21 ～-0.30,P＜0.01),while authoritarian and permissive/neglecting parenting styles were negatively related with positive cognitive emotion regulation (r=-0.11 ～-0.16,P＜ 0.05),and positively related with negative cognitive emotion regulation (r=0.12～0.40,P＜0.05).(4)The mediating effect of cognitive emotion regulation between Authoritative,authoritarian and permissive/neglecting parenting styles and the health risk behaviors of left-behind children respectively were 0.62(87％),0.40(75％) and 0.48(60％).Conclusion The results suggests that parenting styles impact the health risk behavior in left-behind children mainly via the mediating effect of cognitive emotion regulation.

PURPOSE: The study aimed to search and identify genes that were differentially expressed in breast cancer, and their roles in cancer growth and progression. MATERIALS AND METHODS: The Gene Expression Omnibus (Oncomine) and The Cancer Genome Atlas databases (https://cancergenome.nih.gov/) were screened for genes that were expressed differentially in breast cancer and were closely related to a poor prognosis. Gene expressions were verified by quantitative real-time polymerase chain reaction, and genes were knocked down by a lentivirus-based system. Cell growth and motility were evaluated and in vivo nude mice were used to confirm the in vitro roles of genes. Markers of epithelial-to-mesenchymal transition and the associations of KIF11 with the classical cancer signaling pathways were detected by Western blot. RESULTS: A series of genes expressed differentially in patients with breast cancer. The prognosis associated with high KIF11 expression was poor, and the expression of KIF11 increased significantly in high stage and malignant tumor cells. Inhibiting KIF11 expression in lentivirus-suppressed cells revealed that KIF11 inhibition significantly reduced cell viability and colony formation, inhibited migration and invasion, but promoted apoptosis. The sizes and weights of KIF11-inhibited tumors in nude mice were significantly lower than in the negative controls. Western blot showed that E-cadherin in breast cancer was significantly upregulated in KIF-inhibited cells and tumor tissues, whereas N-cadherin and vimentin were significantly down-regulated. BT549 and MDA231 cells with KIF11 knockdown exhibited decreased ERK, AMPK, AKT, and CREB phosphorylation. CONCLUSION: KIF11 acts as a potential oncogene that regulates the development and progression of breast cancer.

PURPOSE: The purpose of this study was to investigate the effect of 21-gene recurrence score (RS) on predicting prognosis and chemotherapy decision in node micrometastases (N1mi) breast invasive ductal carcinoma (IDC). MATERIALS AND METHODS: Patients with stage T1-2N1mi and estrogen receptor-positive IDC diagnosed between 2004 and 2015 were included. The associations of 21-gene RS with breast cancer-specific survival (BCSS), chemotherapy decision, and benefit of chemotherapy were analyzed. RESULTS: We identified 4,758 patients including 1,403 patients (29.5%) treated with adjuvant chemotherapy. In the traditional RS cutoffs, 2,831 (59.5%), 1,634 (34.3%), and 293 (6.2%) patients were in the low-, intermediate-, and high-risk RS groups, respectively. In 3,853 patients with human epidermal growth factor receptor-2 (HER2) status available, most patients were HER2-negative disease (98.3%). A higher RS was independently related to chemotherapy receipt, and 14.0%, 47.7%, and 77.8% of patients in the low-, intermediate-, and high-risk RS groups received chemotherapy, respectively. The multivariate analysis indicated that a higher RS was related to worse BCSS (p < 0.001). The 5-year BCSS rates were 99.3%, 97.4%, and 91.9% in patients with low-, intermediate-, and high-risk RS groups, respectively (p < 0.001). However, chemotherapy receipt did not correlate with better BCSS in low-, intermediate-, or high-risk RS groups. There were similar trends using Trial Assigning Individualized Options for Treatment RS cutoffs. CONCLUSION: The 21-gene RS does predict outcome and impact on chemotherapy decision of N1mi breast IDC. Large cohort and long-term outcomes studies are needed to identify the effects of chemotherapy in N1mi patients by different 21-gene RS groups.

OBJECTIVE: This study aims to establish an effective and stable periodontal ligament cell line stably expressing human telomerase reverse transcriptase (hTERT) gene by using the adenovirus method. METHODS: Polymerase chain reaction (PCR) was used to amplify the full length of hTERT gene to construct recombinant adenovirus plasmid pAd-pshuttle-cmv-hTERT. Packaged adenovirus particles were used for infection of human periodontal ligament cells. The expression levels of hTERT and osteogenic genes, such as alkaline phosphatase, Runt-related transcription factor 2, bone sialoprotein, osteocalcin, osteopontin, and collagen Ⅰ mRNA, were detected by quantitative real-time PCR (qRT-PCR). The ability of osteogenic differentiation was observed by alizarin red staining, and the cell proliferation was determined by CCK-8. RESULTS: Adenovirus particles containing the hTERT gene were successfully constructed and infected with periodontal ligament cells. The infected cells were similar to normal periodontal ligament cells. The qRT-PCR results showed that hTERT and osteogenesis-associated genes were highly expressed in the periodontal ligament cell lines constructed by adenoviruses. Alizarin red staining showed that the periodontal ligament cell line had strong osteogenic differentiation capability. CCK-8 showed that the periodontal ligament cell line had strong proliferation capability. CONCLUSIONS The human periodontal ligament cell line with high efficiency and stable expression of hTERT was established by the adenovirus method, thereby providing an ideal cell line for studying the mechanism of periodontal regeneration.

OBJECTIVE: People in Western Africa suffer greatly from febrile jaundice, which is caused by a variety of pathogens. However, yellow fever virus (YFV) is the only pathogen under surveillance in Sierra Leone owing to the undeveloped medical and public health system there. Most of the results of YFV identification are negative. Elucidation of the pathogen spectrum is required to reduce the prevalence of febrile jaundice. METHODS: In the present study, we used Ion Torrent semiconductor sequencing to profile the pathogen spectrum in archived YFV-negative sera from 96 patients in Sierra Leone who presented with unexplained febrile jaundice. RESULTS: The most frequently identified sequencing reads belonged to the following pathogens: cytomegalovirus (89.58%), Epstein-Barr virus (55.21%), hepatitis C virus (34.38%), rhinovirus (28.13%), hepatitis A virus (20.83%), coxsackievirus (10.42%), Ebola virus (8.33%), hepatitis E virus (8.33%), lyssavirus (4.17%), leptospirosis (4.17%), chikungunya virus (2.08%), Crimean-Congo hemorrhagic fever virus (1.04%), and hepatitis B virus (1.04%). CONCLUSION The distribution of sequencing reads suggests a broader spectrum of pathogens for consideration in clinical diagnostics and epidemiological surveillance in Sierra Leone.

The aim of this study was to systematically evaluate the clinical efficacy of Tripterysium Glycosides Tablets( TGT) alone or in combination with methotrexate( MTX) in the treatment of rheumatoid arthritis( RA) based on the laboratory index criteria and to provide a basis for the clinical application of TGT against RA. Six databases including CNKI,Wan Fang,VIP,PubMed,EMbase and Cochrane were retrieved for randomized controlled trials( RCT) about TGT alone or combination with MTX in the treatment of RA.Then risk assessment tools were used for quality evaluation of the studies,and data extraction and analysis were conducted by using Rev Man 5.3 software for Meta-analysis. A total of 1 709 articles were retrieved,and finally 25 studies were included,with a total sample size of 2 507 cases. Meta-analysis results showed that between TGT alone and TGT alone,MDESR=-2. 66,95%CI[-8.17,2.86],P = 0.35; MDCRP=-2.38,95%CI[-9.01,4.24],P = 0.48; between TGT combined with MTX and MTX alone,MDESR= 8.74,95%CI[6.72,10.76],P<0.000 01; MDCRP= 5.37,95%CI[3.71,7.03],P<0.000 01; SMDRF= 1.05,95%CI[0.51,1.60],P = 0.000 1.The effect of TGT on decreasing CRP and ESR in RA patients was similar to the MTX. In addition,TGT combined with MTX were more effective in decreasing CRP,ESR,RF than MTX alone. However,due to the potential bias in the included studies,more and high-quality randomized controlled trials would be needed to improve the level of evidence.

To systematically review the improvement effects of Tripterygium Glycosides Tables( TGT) alone or in combination with methotrexate( MTX) on the clinical signs and symptoms of rheumatoid arthritis( RA),and provide a basis for the rational use of TGT in clinic,in the current study,six literature databases including CNKI,Wan Fang,VIP,PubMed,EMbase,and Cochrane Library,were systematically searched,according to the inclusion and exclusion criteria. Review Manager 5.3 software was used to input the literatures,and we assessed the risk bias on the level of outcome indicators for each included literature. A total of 18 literatures were included,and the classification results showed that: compared with MTX,TGT alone can reduce the number of joint swelling( MD =0. 18,95%CI[-1.06,1.42],P = 0.78) and joint tenderness( MD =-0.06,95% CI[-1.69,1.56],P = 0.94) in RA patients with the same effect as MTX. In terms of drug combination,TGT combined with MTX had an advantage over MTX alone in lessening the morning stiffness time( MD = 18. 24,95% CI[12. 64,23. 84],P < 0. 000 01) of RA,joint tenderness( MD = 2. 65,95% CI[1. 85,3. 44],P<0.000 01) and joint swelling( MD = 3.01,95% CI[2.09,3.39],P< 0.000 01). In conclusion,this Meta-analysis suggest that TGT alone was superior to MTX in improving joint swelling and tenderness in RA patients,TGT combined with MTX may improve the clinical manifestation of RA patients better than MTX alone.

OBJECTIVE: To evaluate the efficacy and safety of Tongxiening Granules (, TXNG) in the treatment of irritable bowel syndrome with predominant diarrhea (IBS-D). METHODS: A randomized, double-blind, double-dummy, and positive parallel controlled clinical trial was conducted from October 2014 to March 2016. Totally 342 patients from 13 clinical centers were enrolled and randomly assigned (at the ratio of 1:1) to a treatment group (171 cases) and a control group (171 cases) by a random coding table. The patients in the treatment group were administered orally with TXNG (5 g per time) combined with pinaverium bromide Tablet simulator (50 mg per time), 3 times per day. The patients in the control group were given TXNG simulator (5 g per time) combined with pinaverium bromide Tablets (50 mg per time), 3 times per day. The treatment course lasted for 6 weeks. The improvement of Irritable Bowel Syndrome Symptom Severity Score (IBS-SSS) was used to evaluate the primary outcome. Secondary outcomes included adequate relief (AR) rate, Irritable Bowel Syndrome-Quality of Life Questionnaire (IBS-QOL), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and the recurrence rate at follow-ups. Safety indices including the adverse events (AEs) and related laboratory tests were evaluated. RESULTS: Primary outcome: IBS-SSS at baseline, weeks 2, 4, 6 showed no statistical significance in both full analysis set (FAS) and per protocol set (PPS, P>0.05). After 6 weeks of treatment, the total effective rate of IBS-SSS scores in the treatment group (147/171,86.0%) was higher than the control group (143/171, 83.6%) by FAS (P>0.05). In regard to secondary outcomes, after 6-week treatment, there was no significant difference in AR rate, total score of IBS-QOL, improvement of HAMD and HAMA total scores between the two groups (P>0.05). The recurrence rate at 8-week follow-up was 12.35% (10/18) in treatment group and 15.79% (12/76) in control group, respectively (P>0.05). A total of 21 AEs occurred in 15 cases, of which 11 occurred in 8 cases in the treatment group and 10 AEs in 7 cases in the control group. The incidence of AEs had no statistical significance between the two goups (P>0.05). CONCLUSION Tongxiening Granules could relieve the symptoms of patients with IBS-D and the treatment effect was comparable to pinaverium bromide. (No. ChiCTR-IPR-15006415).
