OBJECTIVETo investigate the effect of SIRT6/NF-κB signal axis in delaying hematopoietic stem/progenitor cell senescence with ginsenoside Rg1, in order to provide theatrical and experimental basis for looking for methods for delaying HSC senescence.

METHODSca-1 + HSC/HPC was isolated by magnetic cell sorting (MACS) and divided into five groups: the normal control group, the aging group, the positive control group, the Rg1 anti-senescence group, and the Rg1-treated group. Senescence-associated β-galactosidase (SA-β-Gal) staining, cell cycle analysis and hemopoietic progenitor cell mix (CFU-Mix) were adopted to determine the effect Rg1 in delaying or treating Sca-1 + HSC/HPC senescence biology. The mRNA and protein of senescence regulation molecules SIRT6 and NF-KB were examined by realtime fluorescence quantitative PCR (FQ-PCR) and western blotting.

RESULTCompared with the senescence group, the Rg1 anti-senescence group and the Rg1-treated group showed lower percentage in SA-β-Gal-stained positive cells, decreased cell proportion in G1 phase, increased number of CFU-Mix, up-regulated in SIRT6 mRNA and protein expression, down-regulation in NF-KB mRNA and protein expression. The Rg1 anti-senescence group showed more evident changes in indexes than the Rg1-treated group.

CONCLUSIONRg, may inhibit Sca-1 + HSC/HPC senescence induced by t-BHP by regulating SIRT6/NF-KB signal path.

Objective To analyze the status, changing trends and determinants of mental health of migrant adolescents in junior high schools. Methods All of the data came from China Education Panel Survey (CEPS). CEPS baseline survey was conducted during the 2013-2014 school year by using a stratified multistage probability sampling design. 10 279 nationally representative adolescents from the seventh grade in junior high schools were enrolled in the base school year of data collection and 9 449 participants were followed up at the second wave of data collection during the 2014-2015 school year. Our analytic sample (n=1 645) included all the migrant adolescents who had valid data on mental health. Based on CEPS self-reported mental health scale, t-test method and multivariate linear regression model were used to examine the determinants of mental health of migrant adolescents by performing univariate analysis and multivariate analysis. Results The baseline mental health score of migrant adolescents was (8.33±3.31), higher than that of non-migrant adolescents, and significantly increased to (8.60±3.79) in the follow-up school year. 43.3% of participants had negative mental status at higher frequency as time went on. Sex, cognitive skills, co-residence arrangements, numbers of siblings and school rankings were significant influencing factors for mental health score of migrant adolescents. Conclusions The mental health status of migrant adolescents are more vulnerable than that of non-migrant adolescents and continue deteriorating. Among migrant adolescents, female, those with weak cognitive skills, those who do not live with both parents, those who are not only children and those in schools ranking medium and above are more likely to have a poor mental health state.

OBJECTIVETo investigate the gene mutation in the areas of pre core/core (Pre C/C) and basic core promotor (BCP) of HBV DNA and its clinical significance.

METHODSThe nt 1 735-1 965 segment of HBV DNA was amplified with PCR in 54 cases with chronic hepatitis B and 10 cases with post-hepatitis cirrhosis. Then the PCR product was sequenced.

RESULTSThere were 168 site mutations in 48.5% (33/68) cases with hepatitis B. The first ten mutation sites were nt 1 764 (58.8%), 1 762 (48.5%), 1 799 (21.0%), 1 766 (14.7%), 1 896 (13.2%), 1 754 (8.8%), 1 899 (8.8%), 1 768 (7.4%), 1 814 (7.4%) and 1 913 (7.4%). Three rare mutations of nt 1907, 1 922 and 1 923 were also detected. The mutations of nt 1 896, 1 764 and 1 762 were found in 16.7%, 35.2% and 35.2% of chronic hepatitis, and in 30.0%, 60.0% and 60.0% respectively of post-hepatitis cirrhosis cases. There was statistical significance between the two groups (P < 0.01).

CONCLUSIONThe mutations in the areas of Pre C/C and BCP of HBV DNA might possibly be associated with liver fibrosis. There are many mutation sites in HBV DNA and mutation occurs frequently, therefore gene sequencing is helpful to the design of gene chip and to clinical application.

OBJECTIVETo establish whether Coblation is a suitable modality for removal of early glottic carcinoma.

METHODSFourteen patients with early glottic carcinoma (Tis-T2) without lymph node metastasis underwent resection of laryngeal cancer lesions using transoral endoscopic coblation (TEC), without pre- or post-operative radiotherapy and chemotherapy.

RESULTSNo severe complication such as bleeding and dyspnea occurred in the cases. Only mild postoperative pain happened to the patients. All patients could eat and pronounce on the surgery day. With following-up of 25 - 37 months, no recurrence was observed in 13 cases. One case, with poorly differentiated squamous cell lesion in the anterior commissure invading subglottic, recurred 3 months postoperatively. The patient received the re-resection of laryngeal lesion by coblation, but another recurrence happened to the patient 6 months postoperatively, and then was cured by partial laryngectomy, with recurrence-free survival 21 months postoperatively.

CONCLUSIONThe observation suggests that transoral endoscopic coblation is a reliable and safe modality for the resection of early glottic carcinoma.

OBJECTIVETo observe abnormalities in heart rate variability (HRV) in diabetic rats and to explore the effects of treatment with Guizhi Decoction ([symbols; see text]) on cardiac autonomic nervous (CAN) imbalance.

METHODSA radio-telemetry system for monitoring physiological parameters was implanted into rats to record electrocardiac signals and all indictors of HRV [time domain measures: standard deviation of all RR intervals in 24 h (SDNN), root mean square of successive differences (RMSSD), percentage of differences between adjacent RR intervals greater than 50 ms (PNN50), and standard deviation of the averages of RR intervals (SDANN); frequency domain measures: low frequency (LF), high frequency (HF), total power (TP), and LF/HF ratio]. The normal group was randomly selected, and the remaining rats were used to establish streptozocin (STZ)-induced diabetic model. After 4 weeks, the model rats were divided into the model group, the methycobal group, and the Guizhi Decoction group, 9 rats in each group. Four weeks after intragastric administration of the corresponding drugs, the right atria of the rats were collected for immunohistochemical staining of tyrosine hydroxylase (TH) and choline acetyltransferase (CHAT) to observe the distribution of the sympathetic and vagus nerves in the right atrium. The myocardial homogenate from the interventricular septum and the left ventricle was used for determination of TH, CHAT, growth-associated protein 43 (GAP-43), nerve growth factor (NGF), and ciliary neurotrophic factor (CNTF) levels using an enzyme-linked immunosorbent assay.

RESULTS(1) STZ rats had elevated blood glucose levels, reduced body weight, and decreased heart rate; there was no difference between the model group and the drug treated groups. (2) Compared with the model group, only RMSSD and TP increased in the methycobal group significantly (P<0.05); SDNN, RMSSD, PNN50, LF, HF, and TP increased, LF/HF decreased (P<0.05), and SDANN just showed a decreasing trend in the Guizhi Decoction group (P>0.05). TH increased, CHAT decreased, and TH/CHAT increased in the myocardial homogenate of the model group (P<0.05). Compared with the model group, left ventricular TH reduced in the methycobal group; and in the Guizhi Decoction group CHAT increased, while TH and TH/CHAT decreased (P<0.05). Compared with the model group, CNTF in the interventricular septum increased in the methycobal group (P<0.05); GAP-43 increased, NGF decreased, and CNTF increased (P<0.05) in the Guizhi Decoction group. There were significant differences in the reduction of NGF and elevation of CNTF between the Guizhi Decoction group and the methycobal group (P<0.05). (3) Immunohistochemical results showed that TH expression significantly increased and CHAT expression significantly decreased in the myocardia of the model group, whereas TH expression decreased and CHAT expression increased in the Guizhi Decoction group (P<0.05).

CONCLUSIONGuizhi Decoction was effective in improving the function of the vagus nerve, and it could alleviate autonomic nerve damage.

OBJECTIVETo investigate the anti-fibrosis effects and mechanisms of fenofibrate on hepatic fibrosis using a mouse model of fibrosis induced by carbon tetrachloride (CCl4).

METHODSTwenty-six male C57BL mice were divided into the following three groups: CCL4-induced untreated model control (n = 10), CCl4-induced fenofibrate-treated model (n = 10), and uninduced/untreated normal control (n = 6). All animals were sacrificed after the 5 weeks of induction and treatment. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronic acid (HA) and procollagen III amino-terminal peptide (PIIINP) were determined by routine biochemistry assays. Liver content of hydroxyproline (HYP) was measured by spectrophotometry. Liver content of malonic aldehyde (MDA) and superoxide dismutase (SOD) was measured by enzymatic assays. mRNA expression levels of liver fibrosis-associated factors were determined by PCR, and included alpha-smooth muscle actin (a-SMA), transforming growth factor-beta1 (TGFbeta1), type I collagen-alpha (Collagen1a), peroxisome proliferator-activated receptor-alpha (PPARa), and the inflammatory cytokines tumor necrosis factor alpha (TNFa) and interleukin-6 (IL-6). Finally, the degree of inflammation and fibrosis were assessed by histological analysis using hematoxylin-eosin and Sirius red staining.

RESULTSCompared to the untreated model group, the fenofibrate-treated model group showed significantly lower levels of serum ALT (55.72+/-1.20 vs. 38.72+/-1.25 IU/L), HA (236.20+/-17.57 vs. 152.9+/-13.06 mug/L) and PIIINP (41.66+/-1.89 vs. 34.32+/-1.53 mug/L) (all P less than 0.05). The fenofibrate-treated group also showed a significantly higher level of hepatic SOD content (untreated model: 67.00+/-4.65 vs. 101.1+/-5.32) but significantly lower level of hepatic MDA content (14.67+/-0.93 vs. 10.17+/-0.60 nmol/mg) and lower level of hepatic HYP content (0.67+/-0.80 vs. 0.41+/-0.50 mg/g) (all, P less than 0.05). In addition, the fenofibrate-treated group showed significantly reduced mRNA expression levels of a-SMA (6.83+/-0.88 vs. untreated model: 11.57+/-1.31), TGFbeta1 (67.83+/-4.65 vs. 112.30+/-4.81), Collagen1a (67.83+/-4.65 vs. 112.30+/-4.81), TNFa (17.43+/-2.32 vs. 37.83+/-4.69), and IL-6 (4.00+/-0.49 vs. 5.62+/-0.54), but significantly increased PPARa (0.30+/-0.03 vs. 0.18+/-0.03) (all, P less than 0.05). Finally, the degree of CCL4-induced hepatic fibrosis was attenuated by the fenofibrate treatment.

CONCLUSIONFenofibrate can reduce the degree of liver fibrosis in mice induced by CCl4. The mechanism may involve up-regulation of PPARa, inhibition of the inflammatory response, and enhancement of SOD antioxidant activity.

OBJECTIVETo understand the epidemiological, clinical and etiological characteristics of an Echovirus type 6 meningitis outbreak in Jinzhai county, Liu'an city in Anhui, and to find out the proper way in controlling the aseptic meningitis outbreak.

METHODSA surveillance system for aseptic meningitis was established in Jinzhai to confirm the case definition. Stool or cerebrospinal fluid (CSF) specimens from some cases were collected for entero-viruses isolation and identification. Case-control study was conducted. The case group involved patients while the controls would include: patients' classmate with same gender and the age difference was not over one year. Neutralization antibody in serum specimens were collected and tested in cases and in healthy people.

RESULTS105 cases were distributed in 17 of the 30 towns in Jinzhai county while 41.0% of the cases were in Banzhuyuan town with an incidence rate of 203/10(5). Cases were clustered by school and classroom with age ranging from 3 to 15 years old and the highest as 10.9/10(5) in the 6 to 10 group. The incidence in males was 24.2/10(5) compared to 8.4/10(5) in females. The main clinic characteristics of cases were: fever, headache and vomiting. Echovirus type 6 from 25 of the 72 CSF samples (35%) was isolated. When comparing the cases group with control group, the OR of drinking home-made beverages was 4.1 (95% CI: 1.4-12.0), especially the beverages sacked by plastic bag: 3.3 (95% CI: 1.3-8.8). 6 out of 7 workers engaging in producing home-made beverages were detected to have carried Echovirus type 6 from their stool specimens. The Echovirus type 6 neutralization antibody positive rate in cases (73.5%) was significantly higher than that in 100 healthy people (46.0%) (X2 = 12. 526, P = 0.000).

CONCLUSIONThis episode of meningitis outbreak was caused by Echovirus type 6. The proportion of drinking home-made beverages, especially the beverages sacked by plastic bag in cases group was higher than in control group.
