OBJECTIVETo evaluate the efficacy and potential renal impairment of one-year combination therapy de novo of adefovir dipivoxil (ADV) and lamivudine (LMV) for decompensated cirrhosis related to HBV.

METHODSA total of 36 patients with decompensated cirrhosis related to HBV, nobody had nucleos(t)ide analogs (NAs) treatment history, were recruited and were divided into two group (control group and observation group) randomly. A monotherapy of LMV (100 mg per day) was selected to individuals in control group (n = 18), in contrast, a combination therapy de novo of ADV (10 mg per day) and LMV (100 mg per day) was applied to those in observation group (n = 18). Basic approaches including liver protection, symptom-driven intervention, and supporting therapy, were given to all of the individuals. A course of one year was applied to all. Liver function, Child-Pugh score, serum creatinine (sCr) level, virological response (VR) rate, and virological breakthrough rate were observed pro- and post- treatment, differences between the two populations were analysed statistically.

RESULTS(1) The averages of gender, age, HBeAg status, HBV viral load, sCr level, and Child-Pugh score were all compatible in the two groups at baseline (P > 0.05 for all). (2) At the endpoint of treatment, none of deaths was reported. Comparing with the status before treatment in each group itself, liver function, Child-Pugh score, and viral load were improved statistically (P < 0.01 for all), especially in observed group (P < 0.01 for all variables, vs control group), as for VR rate, result is significant superior to that of control group too (88.89% vs 66.67% , P < 0.05). (3) Virological breakthrough occurred to none in observed group and three cases (16.67%) in control group, all of them were confirmed to be rtM204V variant in the following detection of direct sequencing. (4) Elevated level of sCr didn't arised at the end of treatment in two groups.

CONCLUSIONPresent study reveals that in populations with decompensated cirrhosis related to HBV, one-year combination therapy de novo of ADV and LMV is superior to monotherapy of LMV, and the renal safety is favorable within one year.

OBJECTIVETo investigate the effects of sleep deprivation on intelligence development in primary school students.

METHODSBetween June 2009 and April 2010, 316 grade 5 students aged 10-11 years were selected from four primary schools in four administrative districts of Changsha, China by stratified random sampling. The intelligence characteristics of children with varying degrees of sleep deprivation were investigated using the Chinese Wechsler Intelligence Scale for Children.

RESULTSA total of 286 valid questionnaires were received, with a response rate of 90.5%. The survey was comprised of a sleep deprivation group (sleep time <8 hours per night; n=180) and a control group (sleep time ≥8 hours per night; n=106). The sleep deprivation group had significantly lower subtest scores, verbal intelligence quotient (IQ) (VIQ), performance IQ (PIQ) and full scale IQ (P<0.05) and significantly lower verbal comprehension factor score and memory/attention factor score compared with the control group (P<0.05). Compared with the control group, the moderate sleep deprivation subgroup had significantly decreased VIQ and full scale IQ as well as verbal comprehension factor score and memory/attention factor score (P<0.05), and the severe sleep deprivation subgroup showed decreases in all scores (P<0.05). The sleep deprivation group and moderate and severe sleep deprivation subgroups had significantly higher proportions of children with VIQ-PIQ imbalance than the control group.

CONCLUSIONSSleep deprivation adversely affects intelligence development, especially VIQ, in primary school students, and the adverse effects of sleep deprivation are mainly seen in students with moderate and severe sleep deprivation.

Nivolumab is an anti-programmed cell death (anti-PD-1) monoclonal antibody, which is a new drug for tumor immunotherapy. A 73-year-old female patient with colorectal cancer 3 years after surgery was treated in the Endocrinology Department of Third Xiangya Hospital, Central South University, who developed severe hypothyroidism resulting from treatment with nivolumab. After 4 months treatment of nivolumab, this patient presented with symptoms such as fatigue, dizziness, jaundice and palpebral edema, with decreased levels of FT3 and FT4 and elevated levels of TSH. Subsequently, nivolumab treatment was terminated. This patient's symptoms were relieved and thyroid function returned to normal after thyroxine replacement therapy. The clinical diagnosis was considered to be nivolumab-induced autoimmune thyroid damage, which was an immune-related adverse reaction in the treatment.

Objective: To investigate the association between high sensitivity C-reactive protein (hsCRP) level and new-onset hypertension in different age groups. Methods: This was a prospective cohort study involving non-hypertensive population in Kailuan Group community who participated in health examination between 2006 and 2007.Follow-up was conducted every 2 years, and the time of new onset of hypertension was used as the endpoint of follow-up. The endtime of follow-up for patients without hypertension was the time of death or the last follow-up (December 31, 2017).According to the baseline hsCRP level, the participants were divided into low-risk group (hsCRP<1.0 mg/L), medium-risk group (hsCRP ≥1.0 and ≤3.0 mg/L), and high-risk group (hsCRP>3.0 mg/L), and further stratified by age. Kaplan-Meier method was used to calculate the cumulative incidence of hypertension in each group. Multivariate Cox regression model was used to analyze the association between hsCRP level and new-onset hypertension. Results: A total of 51 179 participants were included in this study, including 38 606 males (75.43%) with an average age of (48.1±12.2) years. The baseline hsCRP was 0.64 (0.25, 1.60) mg/L. The baseline hsCRP was 0.30 (0.16, 0.59), 1.57 (1.20, 2.10), 5.17 (3.80, 7.10) mg/L respectively in low-, medium- and high-risk groups. During the follow-up of (8.1±2.2) years, a total of 9 523 (18.60%) patients developed hypertension, and the cumulative incidence rates of low-, medium- and high-risk groups were 17.41%, 20.48% and 20.73%, respectively. The cumulative incidence of hypertension in low-, medium- and high-risk groups of<45, 45-54, 55-64, ≥65 years old were 13.53%, 15.82%, 16.76%; 19.27%, 22.84%, 21.62%; 21.55%, 24.19%, 24.88%;20.20%, 22.35%, 19.11%, respectively. Except for people aged ≥65 years, there were significant differences in the cumulative incidence of hypertension in low-, medium- and high-risk groups (all P<0.05).Multivariate Cox regression analysis showed that the risk of new-onset hypertension in the high risk group was 1.11 times higher than that in the low risk group (HR=1.11, 95%CI 1.05-1.18). The risk of new-onset hypertension in the high-risk group was 1.22 times (HR=1.22, 95%CI 1.08-1.38), 1.14 times (HR=1.14, 95%CI 1.04-1.26), 1.16 times (HR=1.16, 95%CI 1.04-1.30), and 1.02 times (HR=1.02, 95%CI 0.86-1.20) of the low-risk group, in the<45, 45-54, 55-64, and ≥65 years old groups, respectively. Conclusion: Higher hsCRP level is a risk factor for new-onset hypertension, and the risk of developing hypertension caused by elevated hsCRP is age-dependent.

Paeoniae Radix Rubra is a traditional Chinese medicine commonly used in clinical practice， it is mostly wild and widely distributed in different areas of China. In addition， the plant of Paeoniae Radix Rubra also has ornamental value. Modern phytochemical researches showed that the chemical constituents of Paeoniae Radix Rubra were complex. Up to now， more than 300 chemical constituents have been found， mainly including monoterpene glycosides， triterpenoids， flavonoids， tannins， phenolic acids， saccharides， steroids， volatile oils and so on. Among them， the content of monoterpene glycosides was the highest， and the types of volatile oil were the most. Paeoniae Radix Rubra has a wide range of pharmacological effects， exerting different curative effects in multiple systems such as blood， cardiovascular， nervous and digestive system. It can protect myocardial cells and nerve cells， stabilize microcirculation， anti-endotoxin， anti-atherosclerosis， reduce pulmonary hypertension， anti-depression， protect liver， anti-gastric ulcer， anti-tumor， slow down aging， treat Parkinson's syndrome and diabetes and its complications， anti-radiation， anti-inflammatory， anti-virus and so on. Through reviewing the literature on chemical constituents and pharmacological effects of Paeoniae Radix Rubra， it was found that total glycosides and monomers such as paeoniflorin， albiflorin， benzoylpaeoniflorin and gallic acid may be the main active components of Paeoniae Radix Rubra. At present， the research on Paeoniae Radix Rubra mainly focused on monoterpene glycosides， while the research on flavonoids and volatile oil in Paeoniae Radix Rubra was less. It is suggested that research on these two components should be strengthened in the future.

Objective To summarize clinical characteristics and investigate possible pathogenic gene of Klippel-Feil syndrome(KFS)by the self-designed multigene panel sequencing,so as to decipher the molecular basis for early diagnosis and targeted therapy.Methods From January 2015 to December 2018,we consecutively recruited 25 patients who were diagnosed with KFS in Peking Union Medical College Hospital.The demographic information,clinical manifestations,physical examination and radiological assessments were analyzed.Multigene panel sequencing was performed after DNA extraction from peripheral blood.The possible pathogenic mutations of KFS were explored on the basis of bioinformatics analysis.Results The KFS cohort consisted of 25 patients,including 15 males and 10 females,with a mean age of(12.9±7.3)years.Limited cervical range of motion was the most common clinical feature(12 cases,48%).Based on the Samartzis classification,the proportion of patients suffered from short neck(P=0.031)and limited cervical range of motion(P=0.026)in type Ⅲ KFS was significantly higher than that in type Ⅱ and type Ⅰ KFS.Panel sequencing detected a total of 11 pathogenic missense mutations in eight patients,including COL6A1,COL6A2,CDAN1,GLI3,FLNB,CHRNG,MYH3,POR,and TNXB.There was no pathogenic mutation found in five reported pathogenic genes(GDF6,MEOX1,GDF3,MYO18B and RIPPLY2)associated with KFS.Conclusions Our study has shown that patients with multiple contiguous cervical fusions are more likely to manifest short neck,limited cervical range of motion,and clinical triad.Therefore,these patients need additional attention and follow-up.Our analysis highlights novel KFS-related genetic variants,such as COL6A and CDAN1,extending the spectrum of known mutations contributing to this syndrome and providing a basis for elucidating the pathogenesis of KFS.

The mammalian epididymis not only plays a fundamental role in the maturation of spermatozoa, but also provides protection against various stressors. The foremost among these is the threat posed by oxidative stress, which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids, proteins, and nucleic acids. In mice, the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5 (GPX5) as a major luminal scavenger in the proximal caput epididymidal segment. Accordingly, the loss of GPX5-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx5
