Objective To investigate the effect of cordyceps sinensis from different origins on immune response in mice. Methods Cordyceps sinensis from two origins were prepared into powder, and then the mice were divided into high, middle and low dose(0.4,0.2,0.1 g.kg-1)groups, respectively.In addition, purified water was given as the normal control group.Effects of cordyceps from two different origins were observed by detecting spleen lymphocyte proliferation induced by ConA, delayed type hypersensitivity ( DTH) in mice induced by sheep red blood cells ( SRBC ) , the number of antibody-producing cells, carbon clearance and peritoneal macrophages Swallow fluorescent microspheres, as well as the activity of NK cells. Results The ability of spleen lymphocyte proliferation induced by ConA, carbon clearance and peritoneal macrophages Swallow fluorescent microspheres, and the activity of NK cells were significantly enhanced in the middle and high dose group of two different origins cordyceps, compared with normal control group (P<0.05).Additionally, the number of antibody-producing cells was obviously increased in medium dose group of both origins cordyceps and decreased in the high dose group (P<0.05).The middle and high dose Qinghai cordyceps significantly improved DTH in mice, while Tibet cordyceps sinensis had no obvious effect, and there was significant difference (P<0.05) between the high dose group of Qinghai and three dose groups of Tibet Cordyceps sinensis.In addition, levels of serum hemolysin in mice were significantly increased in the middle and high dose group of Qinghai and high dose group of Tibet Cordyceps sinensis (P<0.05), and the differences of corresponding medium and high doses of two origins were significant ( P<0.05) . Conclusion Cordyceps sinensis of both different regions significantly improved the immune response of mice.However, the efficacy between the two origins was roughly equivalent and had no significant difference.

Aim To investigate the effects of harpagide on cerebral ischemia and the mitochondria mediated Caspase dependent apoptotic signaling pathway in mice.Methods The MCAO was employed to establish MCAO model.When the models were established, the mice were given harpagide (4, 8, 12 mg·kg-1) and edaravone (3.2 mg·kg-1) [0.1 ml·(10 g)-1] by tail vein injection after MCAO immediately.And the model and control mice were given equivalent normal saline by the same way.After MCAO for 6 h, the behavior, volume of cerebral ischemia and pathological changes in the brain were observed.Westernblot was employed to determine the contents of Cyt C in mitochondrion and pro-caspase-3 in endochylema.Results Compared with the model group, harpagide (4, 8, 12 mg·kg-1) could significantly decrease the increased nerve functional score, brain index, brain water content and volume of cerebral ischemia induced by cerebral ischemia.Harpagide (4, 8, 12 mg·kg-1) could reduce the contents of Cyt C in mitochondrion and pro-caspase-3 in endochylema.Conclusion Harpagide may have protective effect on the cerebral ischemia injury in mice, which might be related to the inhibition of the cerebral mitochondria mediated Caspase dependent apoptotic signaling pathway.
8.Report on childhood obesity in China (1)--body mass index reference for screening overweight and obesity in Chinese school-age children.
Biomedical and Environmental Sciences 2005;18(6):390-400
PURPOSETo establish and propose a national body mass index (BMI) reference for screening overweight and obesity in Chinese school-age children and adolescents.
METHODS2000 CNSSCH (Chinese National Survey on Students Constitution and Health) data, including 216 620 primary and secondary school students aged 7 to 18 years old, were used as a reference population. Compared with those of the NCHS international reference, three temporary sets of cut-off BMI were proposed by testing different combinations of P85, P90, and P95. When physiological and biochemical measures between and among "obesity", "overweight", and "normal weight" groups were taken into consideration, set II was selected to be the most appropriate one. The sex-age-specific curves were then plotted and smoothed by using B-spline method.
RESULTSBased on the samples from costal developed metropolis, the BMI curves successfully overcame the shortcomings of lower and level-off tendency of the Chinese total population. Temporary set II, composed by cut-offs of P85 for overweight and P95 for obesity, was finally selected by its sensitivity and peculiarity. BMI 24 and 28 were used as cut-offs for overweight and obesity for both males and females aged 18 years old. These cut-offs, consistent with Chinese Adult's Reference, was proposed as the Body mass index reference for screening overweight and obesity in Chinese school-age children and adolescents.
CONCLUSIONThe new reference clearly showed its superiorty in both prospectivity and actuality. The proposed reference minimized the gaps of the BMI curve between Chinese adolescents and the international reference. Most importantly was that it was consistent with the Eastern Asia ethnic characteristics of body fatness growth. It was therefore proposed by the Working Group on Obesity in China (WGOC) to use it as an nationwide reference for screening overweight and obesity of school-age children and adolescents in China.

Biomedical and Environmental Sciences 2005;18(5):334-340
OBJECTIVETo understand the prevalence and rehabilitation status of autism and mental retardation in China.
METHODSScreening test and clinical assessment were conducted for the diagnosis of autism and mental retardation. The assessment included investigation of the histories of medical conditions and development of these two disorders, utilization and needs for the rehabilitation service, and related intellectual and behavioral appraisal.
RESULTSAmong the 7345 children investigated, the prevalence of autism disorder was 1.10 cases per 1000 children aged 2-6 years (95% CI=0.34 to 2.54), and the prevalence of mental retardation was 10.76 cases per 1000 children (95% CI=8.40 to 13.12). All the children suffering from autistic disorder were intellectually disabled, whereas 31.0% of the non-autism mental retardates had other disabilities. The medical conditions prior to birth and perinatal period were important potential factors for autism. Half of the autistic children and 84% of the children with non-autism mental retardation had never received any rehabilitative service.
CONCLUSIONSThe prevalence of autistic disorder in children aged 2-6 years in Tianjin is rather high. It is urgent to improve the status of the autistic and intelligently disabled young children in China. In order to upgrade the level of early diagnostic and improve the intervention to autism and mental retardation, public awareness and training courses should be heightened.

Objective:To systematically review the severe risk in common chronic diseases and coronavirus disease 2019 (COVID-19) cases.Methods:PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, China Biology Medicine disc, medRxiv, SSRN and ChinaXiv were searched for clinical and epidemiological studies that reported chronic diseases in patients with COVID-19. Only studies of severe COVID-19 in comparison with non-severe controls were included. The prevalence rates of chronic diseases including chronic obstructive pulmonary disease (COPD), diabetes mellitus, hypertension, malignant tumor, cardiovascular diseases, cerebrovascular disease, chronic kidney disease, and chronic liver disease were estimated. Pooled odds ratio ( OR) with 95% confidence interval ( CI) between patients with severe COVID-19 and non-severe groups were calculated. R 3.6.3 software was used for meta-analysis. Results:The search yielded 2 455 articles. A total of 19 eligible comparative studies with 4 792 patients were included in a quantitative analysis. Meta-analysis showed that there was a proportion of 55.0% (95% CI 40.0%-80.0%) male among patients with COVID-19, and the overall pooled prevalence of any chronic diseases in COVID-19 cases was 30.4% (95% CI 24.0%-37.0%). The most prevalent comorbidity was hypertension (16.9%(95% CI 14.0%-20.0%)), followed by diabetes mellitus (8.3%(95% CI 8.0%-9.0%)). The proportion of male patients with severe COVID-19 was higher than that of male patients with non-severe COVID-19 (64.4% vs 52.8%, OR=1.49, 95% CI 1.08-2.05, Z=4.63, P<0.01). The prevalence rates of COPD, cerebrovascular disease, diabetes mellitus, chronic kidney disease, hypertension, cardiovascular diseases and malignant tumor in severe COVID-19 patients were higher than those of non-severe patients ( OR=5.77, 95% CI 3.80-8.74; OR=4.47, 95% CI 2.71-7.38; OR=3.55, 95% CI 2.86-4.40; OR=3.05, 95% CI=1.76-5.28; OR=2.82, 95% CI=1.96-3.97; OR=2.39, 95% CI=1.77-3.23; OR=2.15, 95% CI 1.27-3.66, respectively, Z=8.37, 6.01, 11.60, 4.20, 5.46, 5.71, 3.12, all P<0.01). There was no significant difference in the prevalence of chronic liver disease between severe and non-severe patients ( OR=1.35, 95% CI 0.84-2.17, P=0.11). Conclusion:COVID-19 patients with chronic diseases have higher risk of developing severe disease, and the ORs from high to low are COPD, cerebrovascular disease, diabetes mellitus, chronic kidney disease, hypertension, cardiovascular diseases and malignant tumor.
