Objective　To evaluate the efficiency of low molecular weight heparin(LMWH, fraxiparine) given as a single predialysis bolus injection with reused dialyzers in comparison with standard heparin(SH) administered with a continuous infusion. Methods　30 hemodialysis patients were studied in a radomized crossover fashion. Dialyzers fibrer bundle volumes(FBV), predialysis hemocrit and 2 h clearance of urea, creatinine were observed in the first, the fourth dialysis. The plasma heparin activities(anti-Fxa levels) were measured by the chromogenic substrate assay in 0 h, 2 h, 4 h of dialysis. Results　Significant increase (P<0.05) was seen in the number of dialyzer reuse in LMWH group compared with SH group; there was not significant decrease in dialysis FBV as well as 2 h clearance of urea, creatinine (P>0.05); in addition, the plasma heparin activity(anti-Fxa levels) were comparable in both groups after 2 h of dialysis, however, they were significantly higher after 4 h in the LMWH than those in the SH group (P<0.05). Conclusion　LMWH as a single bolus dose can prevent decrease in dialyzer clearance. It is clinically worthy of further popularity.

This study is designed to obtain recombinant human acetylcholinesterase (rhAChE) and apply it in screening acetylcholinesterase inhibitors. The rhAChE was overexpressed in HEK293 cells transfected by plasmid of pCMV-AChE with the cationic liposome and rhAChE was found to be secreted into cell culture medium. AChE activity was assayed according to modified Ellman method to obtain kinetic parameters. IC so50 values for donepezil compounds of rhAChE were calculated to determine their activities of inhibition. The results showed that Km value was 151.9 micromol.L-1 donepezil inhibited rhAChE in a mixed competitive-noncompetitive way (Ki= 16.03 nmol.L-1, Ki = 18.36 nmol.L-1) and that most new compounds tested exhibited high activities of inhibition on rhAChE. The study suggests that rhAChE is available to be applied in screening AChE inhibitors in vitro.

Objective To observe the clinical efficacy of acupuncture at Xinming points (Extra) plus strong rein-forcing mani- pulation in treating optic atrophy.Methods Forty (56 eyes) optic atrophy patients were randomly allocated to a treatment group of 20 cases (29 eyes) and a control group of 20 cases (27 eyes). The control group received conventional medications, and the treatment group received acupuncture at Xinming points (Extra) plus strong reinforcing manipulation in addition. The visual acuity, the mean visual sensitivity (MS) of visual field and the P100 wave latency of P-VEP were recorded in the two groups before and after the treatment. The clinical therapeutic effects were compared between the two groups.Results The visual acuity, the MS of visual field and the P100 wave latency of P-VEP were significantly changed after treatment in both two groups (P<0.05). After the treatment, there were statistically significant differences in the visual acuity, the MS of visual field and the P100 wave latency of P-VEP between the two groups (P<0.05). The total efficacy rate was 75.0% in the treatment group versus 35.0% in the control group, and the difference was statistically significant (P<0.05).Conclusions Acupuncture at Xinming points (Extra) plus strong reinforcing manipulation is an effective method for optic atrophy.

OBJECTIVETo study the primary and secondary factors of the allergic history, the frequency of acupoint application and the time of acupoint application in the treatment of bronchial asthma and optimize its scheme.

METHODSEighty patients of bronchial asthma were selected as the subjects in the orthogonal trial. The herbal medicines were the empirical formula of acupoint application (prepared at the ratio as 2:2:1:1:1:1:1:1:1 of,, unprocessed,,,,,and) and used on bilateral Feishu (BL 13), Xinshu (BL 15), Geshu (BL 17) and Shenshu (BL 23). Firstly, two groups were divided according to allergic history (40 cases with allergic history and 40 cases without allergic history), and then four subgroups were divided on the basis of the two main groups, 10 cases in each one. Through studying three factors and two levels, i.e. allergic history (Factor A:A:with allergic history; A:without allergic history), the frequency of acupoint application (Factor B:B:4 times; B:10 times, in which, in the group of 4-time applications, the application was given once every 10 days; in the group of 10-time applications, the application was given once every 4 days); and the time of application (Factor C:C:4 h; C:8 h), the optimal scheme was screened on the basis of the attack frequency before and after treatment and the score of the asthma quality life questionnaire (AQLQ) before treatment and 6 months after treatment in the patients of each group.

RESULTS① The orthogonal trial indicated that the best optimal scheme was ABC, meaning the patients with allergic history were treated with acupoint application for 10 times, remained for 4 h. ②Factor B (frequency of acupoint application) and C (time of acpoint application) were the significant influential factors of AQLQ scores (both<0.05). ③The comparison of the attack frequency and AQLQ score before and after treatment in all of the patients showed that the different combinations of factor levels induced the different impacts on the asthma attack frequency and AQLQ scores. Except in the group No.1 and the group No.5, the improvements were all significant in the rest groups, indicating the significant differences (<0.05,<0.01).

CONCLUSIONSAcupoint application reduces apparently the attack frequency of asthma in the patients and improves the living quality. The primary and secondary relationship among the allergic history, the frequency of acupoint application and the time of acupoint application for the impacts on the therapeutic effects are:the frequency of acupoint application > the time of acupoint application > the allergic history. The best optimal scheme is ABC, meaning the patients with allergic history are treated with acupoint application for 10 times, remained for 4h.

OBJECTIVE: To investigate the molecular genetic mechanism of Charcot- Marie-Tooth (CMT) disease in a pedigree. METHODS: Genomic DNA was extracted from the peripheral blood of the family members of a pedigree with autosomal dominant CMT disease, and 65 candidate genes of the proband were screened using target exon capture and the next generation sequencing, and the suspicious genes were verified using Sanger sequencing. PolyPhen-2, PROVEAN and SIFT software were used to predict the function of the mutant genes, and PyMOL-1 software was used to simulate the mutant protein structure. RESULTS: A heterozygous missense mutation [c.371A>G (p.Y124C)] was detected in exon 3 of gene of the proband. This heterozygous mutation was also detected in both the proband's mother and her brother, but not in her father. Multiple sequence alignment analysis showed that tyrosine at codon 124 of GDAP1 protein was highly conserved. All the 3 prediction software predicted that the mutation was harmful. Molecular structure simulation showed a weakened interaction force between the amino acid residues at codon 124 and the surrounding amino acid residues to affect the overall stability of the protein. CONCLUSIONS The mutation of gene may be related to the pathogenesis of autosomal dominant AD-CMT in this pedigree. The newly discovered c.371A>G mutation (p.Y124C) expands the mutation spectrum of gene, but further study is needed to clarify the underlying pathogenesis.
