Bloodletting acupuncture at -well points along three- meridians of foot combined with acupuncture on migraine:a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the analgesic effect of bloodletting acupuncture at -well points along three- meridians of foot combined with routine acupuncture and simple routine acupuncture on migraine.@*METHODS@#A total of 60 patients with migraine were randomized into an observation group and a control group, 30 cases in each one, of which, 4 cases were dropped out in the observation group, 1 case was dropped out in the control group. In the observation group, bloodletting acupuncture at -well points combined with routine acupuncture were applied. The bloodletting acupuncture was applied at corresponding -well points of three- meridians of foot [Lidui (ST 45), Zhiyin (BL 67), Zuqiaoyin (GB 44)] according to pain location. And routine acupuncture was adopted at Sizhukong (TE 23), Shuaigu (GB 8), Taiyang (EX-HN 5), Fengchi (GB 20), Hegu (LI 4), Taichong (LR 3), Zulinqi (GB 41), Yanglingquan (GB 34) and Waiguan (TE 5). In the control group, routine acupuncture was applied, acupoint selection and operation were the same as the observation group. The treatment was given once a day, 30 min a time, 5 days as one course with 2 days interval, and 2 courses were required. Before treatment, immediately after needle withdrawal, 4 h after needle withdrawal and after 2 courses of treatment, the visual analogue scale (VAS) score was compared in the two groups. Before and after treatment, the migraine comprehensive score was observed in the two groups, and the therapeutic effect was evaluated.@*RESULTS@#Immediately after needle withdrawal, 4 h after needle withdrawal and after 2 courses of treatment, the VAS scores in the two groups were decreased (0.05).@*CONCLUSION@#Bloodletting acupuncture at -well points along three- meridians of foot combined with routine acupuncture and simple routine acupuncture have analgesic effect, and the combined therapy is superior to simple routine acupuncture.

Prior periodontal intervention lowers incidence of lower respiratory infection in patients receiving oral and maxillofacial tumor surgery / 南方医科大学学报

The one-time periodontal intervention was completed within 24 h in the intervention group and two-week mouthwash was prescribed in the control group before oral and maxillofacial tumor surgery. Five periodontal indexes were examined at baseline and at 6 weeks after the treatment. The clinical symptoms and incidence of lower respiratory infections were compared between the two groups at 6 weeks.</p><p><b>RESULTS</b>The PLI, BOP, PPD, and CAL were significantly lower and GR was higher in the intervention group than in the control group (P<0.01). The periodontal status was significantly improved in the intervention group. The incidence of lower respiratory infection was significantly lower in the intervention group than in the control group (2.22% vs 7.11%, P<0.01). The incidences of cough and expectoration in the intervention group were significantly lower than those in control group (P<0.01).</p><p><b>CONCLUSIONS</b>Periodontal infection is one of the risk factors for lower respiratory infection after oral and maxillofacial tumor surgery. The periodontal status can be effectively controlled and improved by periodontal intervention. Compared with mouthwash, periodontal intervention can significantly reduce the incidences of cough and expectoration and lower the incidence of lower respiratory infections.</p>

Significance of V444A polymorphism of ABCB11 gene in neonatal cholestasis / 中华实用儿科临床杂志

Objective To explore the association between one common variant in ABCB11-1331T ＞ C (V444A) and neonatal cholestasis.Methods One hundred and ninety-two children with neonatal cholestasis were enrolled as case group,and 196 healthy children were selected as healthy control group.The SNP site of V444A was tested by fluorescent quantitative PCR.Fisher's exact test was performed to detect the differences in allele and genotype distribution between the 2 groups.Wilcoxon rank-sum test was used to test the differences of total bilirubin,total bile acid,γ-glutamyl transpeptidase levels among the patients with different genotypes.Results TT,TC and CC genotypic distribution of V444A were not significantly different between patients and controls (P =0.530).The T allele in the case group accounted for 29.9％,in the healthy control group accounted for 26.3％,there was no significant difference between the 2 groups(OR =1.12,P =0.264).Total bilirubin,total bile acid,γ-glutamyl transpeptidase levels in patients with different genotypes of V444A were also not statistically different (all P ＞ 0.05).Conclusion Only V444A variant may have no impacts on neonatal cholestasis.

Simultaneous separation and detection of principal component isomer and related substances of raw material drug of ammonium glycyrrhizinate by RP-HPLC and structure confirmation / 药学学报

A simple, fast and sensitive analytical method for the simultaneous separation and detection of 18alpha-glycyrrhizinic acid, 18beta-glycyrrhizinic acid, related substance A and related substance B by RP-HPLC and drug quality standard was established. The structures of principal component isomer and related substances of raw material drug of ammonium glycyrrhizinate have been confirmed. Reference European Pharmacopoeia EP7.0 version, British Pharmacopoeia 2012 version, National Drug Standards of China (WS 1-XG-2002), domestic and international interrelated literature were referred to select the composition of mobile phase. The experimental parameters including salt concentration, pH, addition quantities of organic solvent, column temperature and flow rate were optimized. Finally, the assay was conducted on a Durashell-C18 column (250 mm x 4.6 mm, 5 microm) with 0.01 mol x mL(-1) ammonium perchlorate (add ammonia to adjust the pH value to 8.2) -methanol (48 : 52) as mobile phase at the flow rate of 0.8 mL x min(-1), and the detection wavelength was set at 254 nm. The column temperature was 50 degrees C and the injection volume was 10 microL. The MS, NMR, UV and RP-HPLC were used to confirm the structures of principal component isomer and related substances of raw material drug of ammonium glycyrrhizinate. Under the optimized separation conditions, the calibration curves of 18 alpha-glycyrrhizinic acid, 18beta-glycyrrhizinic acid, related substance A and related substance B showed good linearity within the concentration of 0.50-100 microg x mL(-1) (r = 0.999 9). The detection limits for 18alpha-glycyrrhizinic acid, 18beta-glycyrrhizinic acid, related substance A and related substance B were 0.15, 0.10, 0.10, 0.15 microg x mL(-1) respectively. The method is sensitive, reproducible and the results are accurate and reliable. It can be used for chiral resolution of 18alpha-glycyrrhizinic acid, 18Pbeta-glycyrrhizinic acid, and detection content of principal component and related substances of raw material drug of ammonium glycyrrhizinate. It is concluded that the separation of principal component isomer of raw material drug of ammonium glycyrrhizinate and the validity of the substance's structure assignments of retention time being 1.2 in the European pharmacopoeia EP7.0 version, British pharmacopoeia 2012 version remains open to question. It may be of practical value for the quality control of raw material drug, preparation, and Chinese herbal medicine of ammonium glycyrrhizinate.
