Dyslipidemia is a risk factor for cardiovascular diseases (CVDs) in patients with diabetes, and non-high-density lipoprotein cholesterol (non-HDL-C) is a better predictor of CVDs than low-density lipoprotein cholesterol (LDL-C) in patients with diabetes. Therefore, we aimed to investigate the distribution of non-HDL-C and the prevalence of high non-HDL-C level in Chinese patients with diabetes mellitus and identify the associated risk factors. Non-HDL-C concentration positively correlated with total cholesterol, triglycerides, and LDL-C concentrations. Although both non-HDL-C and LDL-C concentration both related positively with TC concentration, the magnitude of correlation was relatively higher for non-HDL-C. The prevalence of high non-HDL-C (⋝4.14 mmol/L) was higher in two age groups (55-64 years: 46.7%; 65-79 years: 47.3%) than other age groups (18-24 years: 4.2%; 25-34 years: 43.6%; 35-44 years: 38.1%; 45-54 years: 41.0%). It was also higher among overweight (45.1%), generally obese (50.9%), or abdominally obese (47.3%) subjects, compared with normal weight subjects (34.5%). The risk of high non-HDL-C increased with advancing age. Both general obesity [odds ratio (OR)=1.488, 95% confidence interval (CI): 1.003-2.209] and abdominal obesity (OR=1.561, 95% CI: 1.101-2.214) were significantly associated with high non-HDL-C levels.

BACKGROUNDOne of the reasons for poor neuroregeneration after central nervous system injury is the presence of inhibitory factors such as Nogo. Here, we tested the inhibition of Nogo by RNA interference both in vitro and in vivo, using recombinant adenovirus-mediated transfection of short hairpin RNAs, to explore a new method of treatment for spinal cord injury.

METHODSWe designed and cloned two Nogo-specific short hairpin RNAs and an unrelated short hairpin RNA, packaged the clones into adenovirus, and amplified the recombinant virus in 293 cells. We then tested the inhibition of Nogo expression both in vitro in adenovirus-transfected oligodendrocytes and in vivo in spinal cord tissue from adenovirus-transfected spinal cord injury model rats. We tested Nogo expression at the mRNA level by reverse-transcription PCR and at the protein level by Western blotting and immunohistochemistry.

RESULTSIn vitro, the two specific Nogo short hairpin RNAs decreased Nogo mRNA expression by 51% and 49%, respectively, compared with Nogo expression in cells transfected with the unrelated control small hairpin RNA (P < 0.005). Similarly, Nogo protein expression decreased by 50% and 48%, respectively (P < 0.005). In vivo, in spinal cord injury model rats, the two specific Nogo short hairpin RNAs decreased Nogo mRNA expression by 45% and 40%, respectively, compared with Nogo expression in spinal cord injury model rats transfected with the unrelated control short hairpin RNA (P < 0.005). The Nogo protein level was similarly decreased.

CONCLUSIONSWe were successful in specifically downregulating Nogo at the mRNA and protein levels by adenovirus-mediated delivery of short hairpin RNAs, both in vitro and in vivo. This confirms the effectiveness of RNA interference for the inhibition of Nogo gene expression and the efficiency of using adenovirus for delivery. Thus gene therapy may be an effective treatment for spinal cord injury.

OBJECTIVETo investigate the relationship between mutations of rtM204V/I (methionine to valine or isoleucine at position rt204 of reverse transcriptase domain) in the hepatitis B virus (HBV) polymerase gene and the G1896A and G1899A single mutations in the pre-eore (PC) region and the A1762T and G1764A double-mutations in the basal core promoter (BCP) region.

METHODSA total of 2,849 hepatitis B complete genome sequences were retrieved from the GenBank/EMBL/DDBJ. The amino acid sequence of the of reverse transcriptase domain and genome sequences of the PC region and the BCP region were aligned using MEGA4 software. Data were calculated using Microsoft Excel and evaluated using SPSS 13.0 statistical software.

RESULTSAmong the 2, 849 HBV complete genome sequences, 217 (8%) strains were identified with Y(I/V) DD and 120 of those had the YIDD mutation and 97 had the YVDD mutation. Of the 1543 strains (54.2%) with PC-BCP mutations, seven mutation patterns of G 1896A-G 1899A-G 1896A-G 1899A-A 1762T/G 1764A, A 1762T/G 1764AG 1896A, A 1762T/G 1764A-G 1899A, and A 1762T/G 1764A-G 1896A-G 1899A were identified. of YMDD and PC-BCP had a higher incidence than the single YMDD mutation (76% vs 24.0%, x2=45.283, P=0.000). The double-mutations of YIDD and PC-BCP had a higher incidence than the double-mutation of YVDD and PC-BCP (85% vs 64.9%, x2=11.836, P=0.000). The double-mutation for lamivudine resistance of YMDD and PC-BCP had a higher incidence than the double pre-existent YMDD and PC-BCP mutations (89.3% vs 58.9%, x2=27.084, P=0.000). The three mutation patterns of G1896A-G1899A (P=0.000, OR=7.573), A1762T/G1764A-G1899A (P=0.000, OR=6.539) and A1762T/G1764A-G1896A-G1899A (P=0.000, OR=6.596) were associated with a greater risk of developing the YIDD mutation, according to binary logistic analysis.

CONCLUSIONThere is a relationship between the HBV YI/VDD mutation and PC-BCP mutations. Different PC-BCP mutation patterns have different effects on the YI/VDD mutation.

Objective:To observe any effect of virtual reality (VR) training on the cognitive functioning and functional fitness of nursing home residents with subjective cognitive decline (SCD).Methods:Fifty-six of such residents were randomly divided into an observation group and a control group, each of 28. Both groups received health education and routine care, but the observation group was additionally provided with 45 minutes of VR training three times a week for 6 months. The training included Baduanjin, magic, flying bird, supermarket shopping, gravity ball and gym episodes. Both groups′ cognition was evaluated using the subjective cognitive decline questionnaire (SCD-Q), the Montreal cognitive assessment (MoCA), the Rivermead Behavioural Memory Test (second edition) (RBMT-Ⅱ), a digit symbol substitution test (DSST), an animal fluency test (AFT) and trail-making test A-B (TMT A-B). Functional fitness was quantified using the 8-foot up-and-go test (8UGT), a 30-second arm curl test (30sACT), a 30-second chair stand test (30sCST), a back scratching test (BST), the sit-and-reach test (CSRT) and a 2-minute step test (2MST) before and after the 6-month intervention.Results:After the intervention, the average SCD-Q, MoCA, RBMT-Ⅱ, DSST, TMT-A, and TMT-B scores of the observation group were significantly better than before the intervention, and significantly better than the control group′s averages. And except for the back scratching their functional results were also significantly better, on average, than those of the control group.Conclusions:VR training can effectively improve the cognition and functional fitness of nur-sing home residents with SCD. Such training is worthy of promotion and wider application in nursing homes.

The growth and metabolism of bone are controlled by osteogenesis of osteoblasts and absorption of osteoclasts, and osteoblasts play a main role in the process of osteogenesis. Overload will affect proliferation and differentiation of osteoblasts, while the loading mode, intensity, duration and other factors can change the biological properties of osteoblasts and further affect the functional activity of osteoblasts. However, the mechanism of osteoblast response to overload is still at the exploratory stage and needs in-depth study. Numerous studies have demonstrated that icariin, a kind of Chinese herbal medicine, can promote proliferation and differentiation of osteoblasts, and icariin with a certain concentration plays an important role in the repair of osteoblast injuries. In this paper, the response of osteoblasts to overload stimulation and repair of osteoblast injuries by icariin were summarized.

Objective: To investigate the prevalence and risk factors of non-alcoholic fatty liver disease(NAFLD) in patients with chronic hepatitis B(CHB) receiving antiviral treatment. Methods: The cross-sectional study included 3 477 cases with CHB who received antiviral therapy. The prevalence of NAFLD was investigated, and then the risk factors were screened and analyzed by stepwise regression method in CHB patients with NAFLD as the dependent variable and the related influencing factors as independent variables. Results: The prevalence of NAFLD was 24.1% in CHB patients who received antiviral therapy. After adjusting for age and gender, central obesity (OR: 7.44, 95%CI: 6.06 ~ 9.14), hypertension (OR: 1.74, 95%CI: 1.51 ~ 2.20), and triglyceride (OR: 1.52, 95%CI: 1.18 ~ 1.96) were positively associated with NAFLD, and cirrhosis was negatively associated with NAFLD (OR: 0.42, 95%CI: 0.34 ~ 0.53). Patients with long-term antiviral therapy had increased risk of NAFLD. Conclusion A significant proportion of CHB patients receiving antiviral therapy have suffered from NAFLD. Therefore, CHB patients receiving long-term antiviral treatment should pay more attention to the prevalence of NAFLD.

To eliminate viral hepatitis as a public health threat, the World Health Organization has set the ambitious goal of reducing the prevalence of hepatitis B surface antigen (HBsAg) in children to 0.1% by 2030, and the key to this grand goal is cutting off hepatitis B virus (HBV) transmission from mother-to-child. Previously, national and international guidelines for the management of chronic hepatitis B recommended the use of hepatitis B vaccine and hepatitis B immunoglobulin (HBIG) or combination of any in neonates and antiviral drugs for pregnant women with high viral load in late pregnancy. However, a recent study in Thailand found that the addition of antiviral drugs in pregnant women with high viral load in the third trimester did not significantly lower the incidence of mother-to-child HBV transmission, but no case of chronic HBV infection was seen with strict standards hepatitis B vaccine and HBIG combined immunoprophylaxis and the use of tenofovir disoproxil in pregnant women with high viral load in the third trimester. In addition, the incidence of mother –to- child transmission of HBV in the antiviral group was 0, while the incidence of HBV transmission in the placebo group was 2%. Therefore, it is not possible to deny the efficacy of adding antiviral drugs in treating pregnant women with high viral load in the third trimester with combined immunoprophylaxis. There is an urgent need for more real-world studies in clinical practice to further reveal the principles and existing problems of mother- to- child transmission of HBV.
