Objective To analyze mutations in the GJB2 gene in a Chinese patient with keratitis-ichthyosis-deafness (KID)syndrome complicated by cutaneous squamous cell carcinoma. Methods Clinical data were collected from a patient with KID syndrome complicated by cutaneous squamous cell carcinoma. Peripheral blood samples were obtained from the patient and her parents, and DNA was extracted from these blood samples. PCR was performed to amplify the exon 2 of the GJB2 gene followed by direct DNA sequencing. Results A mutation (c.148G > A)was identified at position 148 in exon 2 of the GJB2 gene, which caused a codon change from GAC to AAC and resulted in the substitution of aspartate by asparagine at position 50 in the connexin26 (Cx26)protein (p.Asp50Asn). Inaddition,anothermutation(c. 79G > A), which led to the substitution of valine by isoleucine at codon 27 in Cx26 (p.Val27Ile), was found at position 79 in exon 2 of the GJB2 gene. Neither of the two mutations was detected in the patient′s parents. Literature review revealed that 13 cases of KID syndrome complicated by cutaneous squamous cell carcinoma had been reported in abroad, and the mutation c.148G > A was detected in the GJB2 gene in all the 7 cases finally diagnosed by gene sequencing. Conclusion GJB2 gene mutations may be responsible for the clinical phenotype of KID syndrome in this Chinese patient, and the mutation c.148G > A may be related to the development of cutaneous squamous cell carcinoma.

OBJECTIVE To observe the effect of Qi Kwai Granule particles on the expression of in-terleukin 6 (IL-6), monocyte chemotactic protein 1(MCP-1) and transforming growth factor-β1(TGF-β1) in diabetic nephropathy(DN)rats and evaluate the protective effect of Qi Kwai Granule particles against renal injury of diabetic nephropathy. METHODS This experiment adopts adopted the high-sugar-high-fat diet and intraperitoneal injection of 2％ STZ+unilateral renal ligation to establish rat model of diabet-ic nephropathy.50 model rats were then randomly divided into model group,Irbesartan group,Qi Kwai Granule particles of high, medium, low dose group, 10 rats in each group. 10 normal rats were set as the sham operation group.Intragastric administration for 8 weeks were measured in rats.Measure the value of rat blood glucose by blood glucose meter,the determination of serum interleukin 6(IL-6)con-tent by ELISA, the expression of MCP-1 and TGF-β1by immunohistochemistry method. The value of rat blood glucose were measured by blood glucose meter.Serum interleukin 6(IL-6)were determinat-ed by ELISA.Expression of MCP-1 and TGF-β1were evaluated by immunohistochemistry method.RE-SULTS The blood glucose of Qi Kwai Granule particles of high,medium groups were decreased com-pared with those of the model group(P<0.05).The content of IL-6 of Qi Kwai Granule particles of high, medium groups were reduced(P<0.01). The content of MCP-1, TGF-β1in kidney of Qi Kwai Granule particles of high, medium, low dose groups were decreased (P<0.01).

BACKGROUND:Long course of treatment and complications limit the extensive application of distraction osteogenesis, which cannot meet the clinical requirements. OBJECTIVE:To investigate the effect of general administration of eucommia alcohol extract on new bone regeneration based on the rabbit model of mandibular distraction osteogenesis. METHODS:Twenty-four New Zealand white rabbits were randomly divided into experimental group and control group. Unilateral mandibular distraction osteogenesis model was established by 1 mm/12 h distraction protocol. During the distraction period, the rabbits in the experimental group were intragastricaly administered with eucommia alcohol extract and the control animals received the same amount of physiological saline, respectively. Six weeks later, the animals were sacrificed for osteogenic testing. RESULTS AND CONCLUSION: New bone formation was observed in the distracted gap in both groups. However, the amount, mineralization and biomechanical strength of new regenerated bone in the experimental group were obviously greater than those in the control group by histological observation, dual energy X-ray absorptiometry, micro-CT and biomechanical test. General administration of eucommia alcohol extract can markedly promote distraction osteogensis in rabbit mandibular osteodistraction.

Objective To compare the efficacy, adverse reactions and cost-effectiveness between domestic pantoprazole (Pan Li Su) and imported omeprazole (Losec) in the treatment of non-steroidal anti-inflammatory drugs (NSAID) associated ulcer bleeding.Methods Fifty-eight hospitalized patients with NSAID associated ulcer bleeding were randomly divided into pantoprazole group (n=31)and omeprazole group (n= 27) according to random number table.Pantoprazole group was given 40 mg domestic pantoprazole dissolved 100 ml 0.9% sodium chloride solution intravenously every 12 hours.Omeprazde group was given 40 mg omeprazole dissolved in 100 ml 0.9% sodium chloride solution intravenously every 12 hours.The two groups were both treated for seven days.Finally, the efficacy and adverse effect were observed, and cost-effectiveness was analyzed with pharmacoeconomics.Results The total effective rate of pantoprazole group was 93.5%, omeprazole group was 96.3% .The drugs of the two groups could effectively stop bleeding, the difference was not statistically significant (P= 1.00).The rate of adverse effect was 3.2 % and 7.4 % in the two groups accordingly.The cost-effectiveness ratio (C/E) was 7.76 and 20.73 respectively.Compared with pantoprazole group, the incremental cost-effectiveness ratio of omeprazole group was 454.Conclusions Domesic pantoprazole is an effective, safety and economical medicine for NSAID associated ulcer bleeding.

Streptomyces sp.X-435 isolated from a soil sample collected in the suburbs of Beijing was proved to be a produce Virginiamycin.To improve the productivity of the Virginiamycin of Streptomyces sp.X-435,the spores of strain X-435 were treated with UV.The three types of colony,strawhat,wrinkled,blad,were isolated on Gaose's medium plates after mutation.Among them,the colonies of strawhat type exhibited positive mutation and were picked up as objects of screening.After five generation of mutation,the mutant F5-25-u-28 was selected which potency of Virginiamycin was about 20times higher than that of the beginning strain by flask fermentation and was also genetic stable.

The standardization of acupuncture and moxibustion in Canada is increasingly flouring nowadays:on one hand,acupuncture industry in legislated provinces is in the charge of direct administrative departments and associations of acu-moxi; on the other hand,according to the local situations,relevant regulations have been made,which are concentrated on two aspects-technical and administrative standards.Undoubtedly,Canadian Alliance of Regulatory Bodies for TCM Practitioners and Acupuncturist (CARB),united by each provincial TCM/Acupuncture Administration,is the first step to issue federal standards and establish federal level management institution.However,now the releasing of a fundamental regulatory file is in need of active corporation and publicity from each province and association.Therefore,it shows that the body of standardization in Canada is still not relatively perfect.Through introducing and analyzing the relevant information,the author expects that the readers can know the current development of acupuncture and moxibustion standardization in Canada.
