Though prokaryotic cells could hardly express recombinant human beta nerve growth factor (rhNGF-?) with a proper three-dimensional conformation, using of E. coli as a host for industrial production of rhNGF-? is controversial. Recombinant human beta NGF was expressed in E. coli and was refolded in vitro. The isolated products was shown to be consistent with those expressed and secreted by CHO cells in biochemical characters by SDS-PAGE, RP-HPLC, mass spectrometry, N terminal analysis and bioassay determined using DRG and PC12 cells. The products can be acquired with 95% purity, 1.8 ng/U biological activity from both expression system,which remain invariable biological activity when lyophilized in excipient and store at 37℃?2℃, RH 75%?5% for 3 months. Moreover, the product refolded from inclusion bodies of E. coli shows the predominance in homogeneity and the lower cost.

Objective To observe the curative effect of whole-body mild hypothermia therapy on massive cerebral infarction(MCI).Methods 68 MCI patients were divided randomly into the mild hypothermia group(35 cases) and control group(33 cases).At the basic of routine treatment in the two guoups,the mild hypothermia group received whole-body mild hypothermia therapy,including the cooling blanket cave all the body for decrease temperature,Chlorpromazine(50 mg) plus Promethazine(50 mg),Vecuroniumbromide(200～400 mg),0.9% sodium chloride to 50 ml;and Midazolam(50 mg) plus 0.9 % sodium chloride to 50 ml intravenous infusion slowly by trace-pump and continued 6～11 d.The rectal temperature was maintained between 32～33℃.The curative effect was evaluated according to American National Institute of Health Stroke Scale(NIHSS) scores and Barthel index(BI) pre and post-treatment.The mortality and incidence of epilepsy in the two groups were statistical.Results Compared to pre-treatment,the scores of NIHSS were significantly reduced and BI were apparently increased in the both groups post-treatment(all P

Objective To analyse the correlation of apolipoprotein E genotype and Alzheimer's disease(AD) in old population in Urumqi.Methods The polymerase chain reaction and restriction fragment length polymorphism(PCR-RFLP) techniques were used to detect the distribution of genotype, gene frequency of ApoE alleles in 60 cases with sporadic AD and 90 normals as control.Results The frequency of ApoE?2, ApoE?3, ApoE?4 was 6.67%, 75.83% and 17.50% respectively in AD group, while in control group, it was 13.33%, 79.45% and 7.22% respectively. The frequency of ApoE?4 allele in AD group was higher than that in control group( P

Objective To analyse the association of apolipoprotein E genotype with cerebral infarction and myocardial infarction in the old population of Urumqi. Methods The polymerase chain reaction and restriction fragment length polymorphism technique were used to detect the distribution of genotype and gene frequency of ApoE alleles in 56 cases of cerebral infarction(CI), 60 cases of myocardial infarction (MI) and 104 healthy subjects as control. Results The frequency of ApoE ?3/?4 and ?4/?4 genotypes in CI and MI groups was higher than that in control group(P

OBJECTIVETo observe the difference in the therapeutic effects on knee osteoarthritis (KOA) among auricular electroacupuncture therapy plus isolated moxibustion with Lingxian herbal paste (combined therapy), electroacupuncture (EA) and TDP irradiation.

METHODSEighty-nine cases were randomized into three groups. In the combined therapy group (30 cases), the auricular electroacupuncture therapy was adopted together with the isolated moxibustion with Lingxian herbal paste. The auricular points were xi (AH4), pizhixia (AT4), shenmen (TF4), etc. The Lingxian herbal paste was applied at Yanglingquan (GB 34), Dubi (ST 35), Zusanli (ST 36), Neixiyan (EX-LE 4), Heding (EX-LE 2) and Ashi points. In EA group (29 cases), EA was applied at the acupoints that were same as those in the isolated moxibustion with Lingxian herbal paste. In TDP group (30 cases), TDP irradiation was given at the affected knee. The treatment was given once every day, 10 treatments made one session and there was 1 week at the interval among sessions. Totally, 3 sessions of treatment were required. KOA clinical symptom and physical sign score and the single item pain symptom score of Lequesne index were observed before treatment and 1 week after treatment in the patients of each group separately. The efficacies were compared among the three groups.

RESULTSOne week after treatment, the total score of symptoms and physical signs of the patients in each group was reduced significantly as compared with that before treatment (all P < 0.05). The improvements in the symptoms and physical signs in the combined therapy group were better than those in the other two groups (1.50 +/- 1.57 vs 2.52 +/- 1.82, 2.63 +/- 1.97, both P < 0.05). The improvement in pain in the combined therapy group was also better than that in the other two groups (2.37 +/- 0.81 vs 2.83 +/- 0.92, P < 0.05; 2.37 +/- 0.81 vs 3.03 +/- 0.77, P < 0.01). The curative rate in the combined therapy group was 40.0% (12/30), which was higher than 17.2% (5/29) in EA group and 20.0% (6/30) in TDP group separately (both P < 0.01). The overall efficacy in the combined therapy group was superior to the other two groups (P < 0.05).

CONCLUSIONThe auricular electroacupuncture therapy plus isolated moxibustion with Lingxian herbal paste is advantageous at the total score of the symptoms and physical signs and the overall efficacy in the patients of KOA as compared with EA at the local acupoints and local TDP irradiation.

OBJECTIVE To explore the correlation of allergic rhinitis symptoms in preschool children with the household environment dust mites and house dust-mite-specific IgE, as to provide theoretical basis for pediatric allergic disease prevention and control work. METHODS The children with rhinitis who was born in the Second People's Hospital of Wuhu were selected in this study. When the children were 3 or 4 years old, they were followed up. The allergic rhinitis symptoms integral of the children were evaluated, the household environment dust samples of the children were collected. The content of dermatophagoides pteronyssinus allergen components 1(Der p1) and dermatophagoides farinae allergen components 1(Der f1) in dust samples were determined by the method of enzyme-linked immunosorbent(ELIEA). The children house dust-mite-specific serum IgE(sIgE) level was also examined. RESULTS Pediatric allergic rhinitis symptoms had a positive correlation with dermatophagoides pteronyssinus sIgE and dermatophagoides farinae sIgE(P<0.05); Pediatric allergic rhinitis symptoms had a positive correlation with Derp1 and Derf1(P<0.05). There were no statistically significant correlation between Der p1 and Der f1 exposure levels and dust mite sIgE level (P>0.05). CONCLUSION The allergic rhinitis symptoms of the children are positively correlated with household environment dust mites and dust mites specific IgE. That indicated the severity of allergic rhinitis symptom in children may be determined by detecting specific IgE levels. The prevention of allergic disease and improvement the quality of life of the allergic children can be done by strengthening the health education of dust mites and decreasing the content of bedroom environment dust mites.

ObjectiveTo observe the influence of rehabilitation training on heart rate of stroke patients in the early stage.MethodsThe heart rate (HR) of 30 patients within one week after the onset of stroke was evaluated by FUKUDA DS 880A teleelectrocardiograph and the rating of perceived exertion (RPE) was collected during practicing bridging, rolling and moving the arms.ResultsThe HR of 30 patients was only increased 7.57, 6.23 and 6.57 beats per minute during practicing bridging, rolling and moving the arms. RPE of all patients was less than 11.ConclusionAppropriate rehabilitation training is safety and unable to increase the loading of heart in the early stage after the onset of stroke.
