Objective To analyze blood lipid components in simple obesity children and to explore the effects of obesity in the lipid metabolism and its clinical significance.Methods A total of 90 children,including 50 simple obesity children(obesity group)and 40 normal children(control group),were enrolled in this study.The age ranged from 2.5 to 16.0 years.Their blood lipid profiles of all the children were analyzed.The blood lipid profiles were examined by biochemical analysis,including triglyeride(TG),total cholesterol(TC),low density lipoprotein(LDL) and high density lipoprotein(HDL),and the livers of all the children were analyzed.The blood lipid profiles were examined by ultrasonograph.Results 1.There were no significant differences in age and height in obesity group and control group,but there were significant differences in body mass index(BMI) and blood pressure(P0.05),which had no statistical meaning.3.Liver ultra sonogram showed that 18 cases had fatty liver(36%) in simple obesity children.Conclusions Metabolic disorder of blood lipid is present in simple obesity children,who have a tendency to get fatty liver.LDL is markedly elevated in obesity group.Arteriosclerotic cardiovascular disease should be prevented at earlier period of childhood.

Objective To compare the rehabilitation effect of free rehabilitation, the needle therapy and the hand function recovery machine combined with free rehabilitation on movement function, the feeling function as well as the movement pattern of newly stroke patients with hemiplegia. Methods 49 newly stroke patients were divided into the free rehabilitation group, the acupuncture group and the hand function recovery machinegroup, each group received corresponding intervention. The movement function, the feeling function as well as the movement pattern were compared among the three groups using blind method. Results Brunnstrom evaluation for hands feeling-movement function, the Fugl- Meyer evaluation score showed obvious progress compared to before the treatment, score of fine hand - function assessment of Carrshepherd showed no change. Two weeks after treatment,Brunnstrom evaluation for hands feeling-movement function and the Fugl - Meyer evaluation score showed no difference between the free rehabilitation group and the acupuncture group, but the hand function recovery machine group showed better results than the other two groups. One months after treatment,Brunnstrom evaluation for hands feeling-movement function was different among these groups, but not the Fugl-Meyer evaluation score, the hand function recovery machine group showed better results than the other two groups, still score of fine hand-function assessment of Carrshepherd showed no change. Conclusions Acupuncture, free rehabilitation, hand function recov - ery machine all make progress in hand function recovery for newly stroke patients with hemiplegia, but hand function recovery machine combined with free rehabilitation proved to be the best method. Its effect for hand intricate function needs to be enhanced.

A new phenolic glycoside was isolated from the spikes of Prunella vulgaris. Its structure was elucidated as gentisic acid 5-O-beta-D-(6'-salicylyl)-glucopyranoside by spectroscopic evidence and chemical analysis.

Objective To explore the effects of low molecular weight heparin (LMWH) on the virological and pathological changes of newborn mouse liver congenitally infected with human cytomegalovirus (HCMV).Methods Sixty healthy pure line clean level BALB/c mice which were about 10 weeks old (half were female) were divided into five groups (six pairs in each group).The mice in LMWH intervention group and positive control group were intraperitoneally inoculated with 6.0 lg tissue culture infective dose50 (TCID50) of HCMV AD169; those in blank control group were intraperitoneally injected with 0.5 mL dulbecco's modified Eagles medium (DMEM) ; then all the mice were paired to mate.The pregnant mice in LMWH intervention group Ⅰ were subcutaneously injected with LMWH 1000 U/kg daily for 10 days; those in group Ⅱ were subcutaneously injected with LMWH 1000 U/kg daily for 5 days and their newborn mice were subcutaneously injected with LMWH 1000 U/kg daily for 5 days; those in group Ⅲ were subcutaneously injected with LMWH 1000 U/kg daily for 10 days in their newborn mice.All these newborn mice were sacrificed at day 10 of birth.The liver was removed for virus isolation,dry-wet weight determination,pathology examination and quantitative fluorescence-polymerase chain reaction (PCR) detection.The comparison among groups was done by analysis of variance.Results HCMV was isolated from the supernatant of liver tissue homogenate in 10-day positive control newborn mice,while HCMV was isolated in 24-day newborn mice of the other three groups of LMWH intervention.Pathology confirmed that positive control liver tissue had inflammatory changed,liver cell inflammatory swelling degeneration,vacuoles degeneration,specific HCMV inclusion body in nuclear,and portion of liver cell necrosis,while liver pathological results of LMWH intervention group showed mild liver cell inflammatory changes and slight cell inflammatory swelling degeneration,which were similar to the blank control group.The moisture of liver tissue contents in LMWH intervention group decreased more obviously than positive control group.The HCMV DNA loads in 50 mg liver tissues of LMWH intervention groups Ⅰ,Ⅱand Ⅲ were (3.26±0.43),(3.26±0.41) and (3.32±0.51) lg copy,respectively,which were significantly lower than that of positive control group [(7.38 ± 0.53) lg copy; F =314.620,P0.01],while there were no significant differences among LMWH intervention groups (P＞0.05).Conclusion LMWH intrauterine and postnatal interventions can significantly reduce HCMV DNA replication in hepatocytes,and relieve inflammatory changes in liver tissue.

Objective: To explore myocardial protection effect of artificial subhibernation therapy on rabbits with acute myocardial infarction (AMI) and its possible mechanism. Methods: A total of 24 rabbits were randomly and equally divided into sham operation group, AMI control group and AMI subhibernation group. Changes of their body temperature, heart rate and respiratory frequency were observed. Serum concentration of creatine kinase isoenzyme (CK-MB) was measured by immunosuppression method, and plasma concentration of norepinephrine (NE) was measured by high performance liquid chromatography-electrochemical method. Percentage of myocardial infarct area in left ventricular area (I/LV) and apoptosis index (AI) were compared between two AMI groups. Results: Compared with control group 4 h after establishment of AMI model, there were significant decrease in body temperature [(37.333±0.427)℃ vs. (34.988±0.488)℃], I/LV [(19.281±1.687)% vs. (16.263±2.275)%] and AI [(36.636±1.671)% vs. (34.521±1.356)%], and concentration of CK-MB [(759.863±64.111)U/L vs. (560.225±65.837)U/L] and NE [(200.475±43.581) ng/ml vs. (143.813±43.383) ng/ml] in subhibernation group, P<0.05,or <0.01, but there were no significant changes in heart rate and respiratory frequency between two groups. Conclusion: Artificial subhibernation therapy possesses significant myocardial protection effect on rabbits with acute myocardial infarction through reducing stress response, inducing low temperature and inhibiting cell apoptosis etc.

Objective To identify the species classification of an ornamental Planorbidae from a flower market in Shanghai and analyze its potential distribution in China. Methods In August 2013,six freshwater snail specimens were collected from the Wanshang flower market. The species was identified by morphology and molecular biology. An ecological niche model was constructed based on the native geographic presence occurrence data,and projected onto the whole of China to predict the poten?tial distribution. Results Their shell external morphology suggested that the specimens belonged to Planorbella trivolvis(Say 1817)of Planorbidae,which is native in North America. The sequence data of a fragment of the mitochondrial cytochrome c oxi?dase subunit I(COI)confirmed its identification. A total of 2 294 georeferenced occurrence points in North America were car?ried out from the Global Biodiversity Information Facility databases and 614 records with coordinates were used to produce a North American native niche model by a maximum entropy method(Maxent). The projection on China results suggested high probabilities of occurrence mostly in Henan Province and its borderland with nearby provinces. Conclusions P. trivolvis is sim?ilarly with Biomphalaria species from shell morphology. It is the first records of the species in China,and the field dispersal is not clear.
