Objective: The study aims to predict 10-year cardiovascular disease (CVD) risk and explore its association with sleep duration among Chinese urban adults. Methods: We analyzed part of the baseline data of a cohort that recruited adults for health screening by cluster sampling. The simplified Pittsburgh Sleep Quality Index (PSQI) and Framingham 10-year risk score (FRS) were used to measure sleep duration and CVD risk. Demographic characteristics, personal history of chronic diseases, lifestyle factors were collected using a questionnaire. Height, weight, total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C) were also measured. Multiple logistic regression models were performed to explore the association of sleep duration with the predicted CVD risk. Results: We included 31, 135 participants (median age 44 years, 53.02% males) free of CVD, cerebral stroke, and not taking lipid-lowering agents. Overall, 14.05%, and 25.55% of participants were at medium and high predicted CVD risk, respectively. Short sleep was independently associated with increased odds of medium to high risk of predicted 10-year CVD among males ( Conclusion A substantial number of adults free of CVD were at high 10-year CVD risk. Short sleep was associated with increased odds of predicted CVD risk.

Objective:To introduce the construction of Henan Cerebral Palsy Register and Rehabilitation Management System (HCPRRMS) and to explore the construction project of regional register and surveillance of cerebral palsy. Methods:The construction process, registration content and preliminary results of HCPRRMS were systematically introduced. Results:HCPRRMS was independent developed in 2014. Since March, 2015, the system has been used to register information of patients with cerebral palsy in the Third Affiliated Hospital of Zhengzhou University. Until September, 2019, a total of 23 child rehabilitation institutions had used the registration management system. There were 1357 patients with cerebral palsy registered in this system, in which 936 cases (68.98%) were male, 501 cases (36.92%) were with gestational weeks < 37, 443 cases (32.65%) were with birth weight < 2500 g, and 430 cases (31.69%) were born with hypoxic-ischemic encephalopathy. Among them, the spastic cerebral palsy patients (1117 cases, 86.74%) accounted for the highest proportion. There was significant difference among types of cerebral palsy and the classification of GMFCS. A total of 1117 patients with cerebral palsy showed MRI-identified brain abnormalities, in which, periventricular leukomalacia accounted for the most (480 cases). For the complications, epilepsy accounted for 14.44% (196 cases), vision impairment accounted for 8.03% (109 cases), hearing impairment accounted for 11.64% (158 cases). Among 769 cases aged more than two years, language-speech dysfunction accounted for 52.66% (424 cases); and among 216 cases aged more than four years, mental retardation accounted for 37.96% (82 cases). Conclusion:HCPRRMS could help to understand the risk factors, clinical characteristics, and complications of cerebral palsy.

BACKGROUND: We previously found that the intestinal epithelial chemokine (C-C motif) ligand 7 (CCL7) plays an important role in the development of toxin-induced acute liver damage. The detailed effects of intestinal epithelial CCL7 on chronic diseases; however, are still unclear. Here, we aimed to investigate the impact of intestinal epithelial CCL7 overexpression on high-fat diet (HFD)-induced obesity and steatohepatitis in mice. METHODS: Intestinal epithelial CCL7 overexpression (CCL7) mice and their wild-type (WT) littermates were fed with normal chow or HFD for 16 weeks to induce obesity and non-alcoholic fatty liver disease. Body weight gain, as well as adipose tissue index were assessed. Liver injury was monitored by histological analysis and real time polymerase chain reaction. Gut microbial composition was analyzed by 16S rRNA gene sequencing. RESULTS: We found that the CCL7 mice on a HFD had markedly decreased weight gain (8.9 vs. 17.0 g, P < 0.05) and a lower adipose tissue index that include mesenteric fat (1.0% vs. 1.76%, P < 0.05), gonadal fat (2.1% vs. 6.1%, P < 0.05), subcutaneous fat (1.0% vs. 2.8%, P < 0.05) compared to WT animals. HFD-induced glucose intolerance and insulin resistance were also significantly improved in CCL7 mice compared to WT. Furthermore, HFD-fed CCL7 mice displayed less hepatic lipid accumulation and lower expression of inflammatory factors than WT mice. 16S rRNA gene sequencing demonstrated that CCL7 overexpression in intestinal epithelial cells improved HFD-induced gut microbial dysbiosis. CONCLUSIONS Our study revealed that CCL7 overexpression in the intestinal epithelium protects mice against the progression of diet-induced obesity, hepatic steatosis, and enteric dysbiosis.

Objective To investigate the effects of transient receptor potential vanilloid-1 (TRPV1) antagonist AMG517 on cerebral ischemic / reperfusion injury in mice. Methods Forty male C57BL / 6 mice were assigned to the following groups: sham group, vehicle + ischemia / reperfusion group (vehicle), capsaicin + ischemia / reperfusion group (capsaicin), and AMG517 + ischemia / reperfusion group (AMG517) . Ischemic / reperfusion injury was induced by permanent middle cerebral artery occlusion(MCAO) and neurological deficits were evaluated 72 hours after MCAO. Then, infarct volume, brain edema, mRNA expression of TRPV1 and serum concentrations of tumor necrosis factor α(TNF-α) and interleukin-10 (IL-10) were measured. Results Compared with the vehicle group, AMG517 significantly decreased the infarct volume (P < 0. 01) . Neurobehavioral score significantly decreased following administration of AMG517 (P < 0. 01) 72 hours after MCAO. Compared with the sham group, the mRNA expression of TRPV1 significantly increased in vehicle group (P < 0. 01) . AMG517 significantly increased the anti-inflammatory cytokine IL-10 and decreased the inflammatory cytokine TNF-α (P<0. 05) . Conclusion AMG517 can improve ischemia / reperfusion injury in mice and may play a neuroprotective effect by alleviating inflammation.

OBJECTIVE: Ideal cardiovascular health (CVH) could predict a lower risk of developing cardiovascular diseases. This study was conducted to investigate the association between ideal CVH and subclinical atherosclerosis in a population cohort of Chinese adults aged ⪖ 40 years. METHODS: This study was designed as a cross-sectional analysis of 8,395 participants who had complete data at baseline and a prospective analysis of 4,879 participants who had complete data at 4.3 years of follow-up. Ideal CVH metrics were defined according to the American Heart Association. Subclinical atherosclerosis was evaluated by plaques in carotid arteries, carotid intima-media thickness (CIMT), brachial-ankle pulse wave velocity (baPWV), and urinary albumin-to-creatinine ratio (UACR). RESULTS: Both the prevalence and incidence of atherosclerosis measures were found to be decreased with increasing numbers of ideal CVH metrics at baseline (all P values for trend < 0.01). The levels of CIMT and UACR at follow-up showed an inverse and significant association with the numbers of ideal CVH metrics at baseline (both P values for trend < 0.05) but a borderline significant association with baPWV (P for trend = 0.0505). Taking participants with 0-1 ideal metric as reference, we found that participants with 5-6 ideal metrics had significantly lower risks of developing carotid plaques (odds ratio, OR = 0.46; 95% confidence interval, CI 0.27-0.79), increased CIMT (OR = 0.60; 95% CI 0.42-0.84), and increased baPWV (OR = 0.57; 95% CI 0.34-0.97) after full adjustments. A significant interactive effect of age and CVH was detected on CIMT and baPWV progression (both P values for interaction < 0.05). CONCLUSION The numbers of ideal CVH metrics showed a significant and inverse association with the risk of developing subclinical atherosclerosis in middle-aged and elderly Chinese adults, whereas its dose-response effect was attenuated in individuals aged ≥ 60 years and partially weakened in male participants.

Objective: To observe short-term and long-term efficacies of Danlu Tongdu tablets on lumbar disc herniation (LDH) with kidney deficiency and stasis syndrome, and its effect on nucleus pulposus reabsorption and immunoinflammatory factors. Method: One hundred and sixty patients were randomly divided into control group (80 cases) and observation group by random number table. Patients in control group (80 cases) got acupoint massage and acupuncture, 1 time/day. In addition to the therapy of control group, patients in observation group were also given Danlu Tongdu tablets, 4 tablets/time, 3 times/days. A course of treatment was 12 weeks, and a 9-month follow-up was recorded. Lumbago and leg pain were recorded by visual simulation (VAS) before treatment and at the first, second, third month after treatment. Before and after treatment, Japanese orthopaedic association (JOA), symptoms and signs were scored. During the 9-month follow-up, relapse rate and relapse time were recorded, and VAS and JOA were scored. Absorption of nucleus pulposus was assessed, and levels of interleukin-1 (IL-1), IL-17, tumor necrosis factor-α (TNF-α), matrix metalloproteinases-3 (MMP-3) were detected. Result: By rank sum test, the clinical efficacy in observation group was better than that in control group (Z=2.125, P<0.05), and scores of JOA was better than that in control group (Z=1.924, P<0.05). At the first, second and third months after treatment, VAS scores of low back pain, leg pain were lower than those in control group (P<0.01), while the decline range were more than that in control group (P<0.01). And scores of symptoms and signs were lower than that in control group (P<0.01), whereas scores by dimensions of JOA scale and the total score of JOA were all higher than those in control group (P<0.01). Complete absorptivity of nucleus pulposus in observation group was 61.11%, which was higher than 42.03%in observation group (χ²=5.138, P<0.05). Levels of IL-1, IL-17, TNF-α and MMP-3 were lower than that in control group (P<0.01). Relapse rate in observation group was 23.61%, which was lower than 40.58%in control group (χ²=4.668, P<0.05). Average recurrence time was longer than that in control group (P<0.05), score of VAS was lower than that in control group (P<0.05), and the total score of JOA was higher than that in control group (P<0.05). Conclusion: In addition to acupuncture and massage therapy, Danlu Tongdu tablets can also be used to relieve pain and ameliorate function, improve clinical efficacy, reduce relapse rate, promote nucleus pulposus reabsorption, and relieve inflammation of nerve root.
