Objective To investigate the feasibility and outcome of resection and reconstruction of hepatic artery in hilar cholangiocacinoma (HCC).Methods The data of 29 patients with HCC with hepatic artery reconstruction carried out from March 2009 to August 2013 in our center were retrospectively analyzed.23 right hepatic arteries and 6 common hepatic arteries were involved.In-situ anastomosis was carried out in 20 patients and a double anastomosis using gastrodoudenal artery grafts was carried out in 9 patients.Results There were no arterial thrombosis or other related complications on prolonged follow-up.Conclusion Hepatic artery resection and reconstruction should be carried out if the artery was invaded by a hilar cholangiocarcinoma to produce a high resection rate and a better outcome.

With the advance of drug development and research techniques, the drug metabolic processes and mechanism can be more deeply achieved. As the drug metabolism and pharmacokinetics process are mediated by drug metabolizing enzymes and transporters, study of drug metabolizing enzymes and transporters has become an important part for drug development. The traditional immunoassays with low sensitivity and poor specificity can not reflect the accurate expression level of drug metabolizing enzymes and transporters. We now give a brief review on the quantitative study of drug metabolizing enzymes and transporters by mass spectrometry-based proteomic approach.

Objective To observe effect of scalp acupuncture combined with cognitive rehabilitation training in ameliorating cognitive dysfunction in stroke patients. Methods Eighty-four stroke patients with cognitive dysfunction were randomly divided into a treatment group ( n = 42) and a control group (n = 42 ) . All of the patients in both groups received routine therapy including cognitive rehabilitation training by professional therapists aimed at improving their orientation, perception, attention and thinking. The patients in the treatment group also received prolonged scalp acupuncture, in which the acupuncture needle remained in the scalp for 6 hours. All cases were evaluated using Loewenstein's occupational therapy cognition assessment (LOTCA) before and 10 weeks after treatment. Results The LOTCA scores were significantly different before and after treatment in both groups. The effect in the treatment group was significantly better than in the control group. Conclusions Prolonged scalp acupuncture combined with cognitive rehabilitation training can significantly improve the cognitive ability of stroke patients.

OBJECTIVETo elucidate the development of mapping and localization of susceptible genes on chromosomes to asthma related phenotypes.

DATA SOURCESPublished articles about susceptibility genes for asthma related phenotypes were selected using PubMed.

STUDY SELECTIONUsing methods of candidate gene positional clone and genome-wide scan with linkage and association analysis to determine the location in the genome of susceptibility genes to asthma and asthma related phenotypes.

RESULTSThere are multiple regions in the genome harboring susceptibility genes to asthma and asthma related phenotypes, including chromosomes 5, 11, 12, 6, 2, 3, 13, 7, 14, 9, 19 and 17. Many of these regions contain candidate genes involved in asthma development and progression. Some susceptible genes may affect the phenotype expression or response to therapy. In addition, the interaction of multiple genes with the environment may contribute to the susceptibility to asthma.

CONCLUSIONSAs an essential step toward cloning the susceptible genes to asthma, fine mapping and localization on chromosomes are definitely needed. Novel powerful tools for gene discovery and the integration of genetics, biology and bioinformatics should be pursued.

Objective To summarize the clinical experience of hepatic artery bypass reconstruction using gastroduodenal artery in radical resection of hilar cholangiocarcinoma,and to provide assistance for surgeons applying artery reconstruction technique correctly in radical operation of hilar cholangiocarcinoma.Methods 9 cases of hilar cholangiocarcinoma with hepatic artery invasion wcrc subjected to radical resection combined with tumor invaded hepatic artery resection and reconstruction.Hepatic artery bypass reconstruction was performed by end-to end anastomosis,using the gastroduodenal artery interposition graft.The clinical data of these patients were reviewed retrospectively.Results All tumors of these cases with hilar cholangiocarcinoma were involved right hepatic artery,and the in volvement length was not less than 2 cm.The artery reconstruction was one-time successfully per formed in all cases.The median time required for anastomosis was (23.0±3.1) min.No postoperative complications,the dysfunction of gastrointestinal peristalsis or abnormal gastric drainage volume for example,related to the gastro-duodenal artery resection was observed.None of the patients devel oped any complications related to the arterial bypass reconstruction in the follow-up period,which was confirmed by abdominal CT scan.Conclusion Hepatic bypass reconstruction using gastro duodenal artery graft decreases the morbidity related to artery reconstruction and has little effect on gastrointes tinal function,which is the optimal choice for arterial reconstruction in radical operation for hilar cholangiocarcinoma.

Objective To develop a new strategy for preparing large-area full-thickness skin grafts with donor incisions small enough to allow direct suture under low pressure.Methods A geometrical analysis was carried out to design the best strategy to obtain skin grafts with minimal donor defect.In this strategy,two semicircular donor skin grafts are subjected to a malpositioned joining to form a circle which is equal in size to the large-area skin defect.Seven patients with cutaneous malignancy were managed by this operation regimen,including three cases of basal cell carcinoma,three cases of squamous cell carcinoma,and one case of malignant melanoma.Tumors were located in the face or head in five patients,and in feet in two patients.Results The width of donor incisions was significantly reduced by this strategy,and donor defects were sutured directly with the minimal loss of donor graft.Of the five patients with malignancies of the head or face,three achieved complete survival of skin grafts,two experienced mild erosion at the margin of skin grafts.A 10％-20％ necrosis of skin graft was observed in the sole of feet in 2 patients,which healed 1-2 months after dressing changes.Conclusion Joined grafts of equal size may be an effective approach to the repair of large skin defect.

To optimize the water extraction process for glycyrrhiza. Methods: HPLC was used to determine the con-tents of glycyrrhizic acid and liquiritin. The comprehensive index included the contents of glycyrrhizic acid and liquiritin and the yield of dry extract. The water amount and the extraction time were selected as the independent variables, and the comprehensive index was set as the dependent variable. Design-expert 8. 06 software was used to fit multivariate linear or quadratic multinomial models for the experimental values. Response surface methodology was used to optimize the water extraction process. The prediction was carried out through comparing the observed and predicted values. Results:The regression coefficient of binomial fitting complex model was as high as 0. 979 7. The optimum conditions of extraction process were as follows:12-fold amount of water, extracting 3 times with 90 min for each time. The deviation between the observed and predicted values was -1. 72%. Conclusion: Central composite design-response surface methodology is convenient and highly predictive in optimizing the water extraction process for glycyrrhiza, which can be applied in the further membrane separation and purification.

The clinical efficacy of acupuncture and moxibustion for post-stroke constipation was systematically reviewed. By computerized and manual retrieval of clinical research literature regarding acupuncture and moxibustion for post-stroke constipation, the randomized control trials (RCTs) that met the inclusive criteria were collected. Cochrane systematic review method was used and Revmen 5.2 software was adopted to perform this Meta analysis. Totally 8 articles were included, involving 610 cases of post-stroke constipation. As a result, the total effective rate and cured rate of acupuncture and moxibustion for post-stroke constipation were significantly superior to those of the control group [total effective rate: OR = 2.10, 95% CI (1.25, 3.54), Z = 2.78, P = 0.005; cured rate: OR = 2.37, 95% CI (1.57, 3.58), Z = 4.10, P < 0.0001]. This result indicated that acupuncture was effective for post-stroke constipation and had some advantages compared with other therapies. But the quality of included RCTs was low, and high-quality, large-sample and multi-center RCTs were needed to perform further verification.
