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.

A total of 906 subjects with no history of diabetes who had undergone coronary angiography were included in this study and categorized into four groups according to the level of fasting plasma glucose (FPG):≤5.5 mmoL/L,5.6-6.0 mmol/L,6.1-6.9 mmoL/L,and ≥ 7.0 mmol/L.Significant coronary artery disease (CAD) was defined as ≥ 50％ reduction of lumen diameter at least in one major coronary artery.The severity of coronary atherosclerosis was defined by the Gensini score.The clinical data,laboratory indexes,and coronary angiography results were compared among various groups.The risk factors for the prevalence and severity of angiographic CAD were analyzed.The results showed that the prevalence of angiographic CAD,the number of diseased vessels,and the Gensini score were increasing with increasing FPG levels among four groups (P＜0.05 or P＜0.01).The FPG level was significantly correlated with angiographic CAD (P =0.004) and the Gensini score (P =0.010),suggesting that FPG was an independent risk factor for the prevalence and severity of angiographic CAD.

OBJECTIVETo observe the effect differences on post-stroke dysphagia among acupoint injection combined with neural electrical stimulation, acupoint injection, neural electrical stimulation, and swallowing training respectively, so eligible intervention can be applied to this kind of disease.

METHODSOne hundred and eight-three patients of post-stroke dysphagia were randomized into a comprehensive treatment group (42 cases), an acupoint injection group (44 cases), a neural electrical stimulation group (49 cases) and a swallow training group (48 cases) and were treated with the comprehensive therapy of acupoint injection and neural electrical stimulation, acupoint injection, neural electrical stimulation and swallowing training separately. The treatments for 10 days made one session. There were 3 days at the interval among treatment sessions and 3 sessions were required totally. The cases in those treatment groups were blankly controlled with the other 47 patients of post-stroke dysphagia. All the patients received basic rehabilitation treatment. The modified water swallowing test was conducted to assess the efficacy before treatment, 10 days after treatment and 30 days after treatment in each group separately. The clinical efficacy, score of water swallowing test and improvement in water swallow test were compared among the groups.

RESULTSAfter 10-day treatment, the differences in efficacy and score of water swallow test were not significant in each group (all P > 0.05). After 30-day treatment, the effective rate (94.29%, 33/35) in the comprehensive treatment group was apparently better than 68.75% (22/32) in the acupoint injection group, 80.00% (32/40) in the neural electrical stimulation group, 67.50% (27/40) in the swallowing training group and 42.86% (12/28) in the blank group separately. The score in water swallow test in the comprehensive treatment group was lower than that in each of the other groups (1.37 ± 0.60 vs 2.03 ± 1.00, 1.90 ± 0.90, 2.20 ± 0.72, 2.71 ± 0.90, all P < 0.05). The differences in the effective rate and score in water swallow test were not significant among the acupoint injection group, neural electrical stimulation group and swallowing training group (all P > 0.05), which indicated that the improvement in swallowing function in the comprehensive treatment group was significantly superior to the other groups (all P < 0.05).

CONCLUSIONThe comprehensive therapy of acupoint injection and neural electrical stimulation achieves the much better efficacy on post-stroke dysphagia.

Tetraspanins belongs to the transmembrane 4 superfamily(TM4SF). They can be as a bridge to connect the proteins outside or inside the cell membrane. A tetraspanins web is formed by the tetraspnins-proteins complex, and the web is believed to involve in fundamental functions of immunity system, and consequnently, signaling between cells and inside cells, regulating cell activation and adhesion, participating in the identification and infection of some virus. As a family of conservative transmembrane proteins, tetraspanins play multiplex roles in invertebrate. It was described how tetraspanin microdomains might have functions in the immune system, and how they contact with virus. In addition, the important role of tetraspanins in the innate immune system of invertebrate were discussed.
