Aim To investigate the effects of isoliquiritigenin(ISL) on cognition dysfunction and brain energy metabolism following repeated cerebral ischemia-reperfusion in mice.Methods Mouse models of learning and memory deficits were made by repeated occlusion of bilateral common carotid arteries and reperfusion. Step-down test and Y-maze task were used to examine the learning and memory abilities of mice. The brain energy state was analyzed by reversed-phase high performance liquid chromatogra phy. Results ISL 10, 20 and 40 mg?kg -1 ig reduced the n umber of errors and extended the latency of memory in step-down test, decreased the number of cumulated stimulation and increased the number of right choices i n Y-maze task. ISL(10, 20, 40 mg?kg -1) increased the levels of ATP, ener gy charge (EC) and total adenine nucleotides(TAN) in a dose-dependent manner. Conclusion The results suggest that ISL improves cognition dysfun ction induced by repeated cerebral ischemia-reperfusion in mice, which may be r elated to the improvement of brain energy metabolism.

Objective To study the effect of liver transplantation using right liver lobe Ⅴ and Ⅷ segments with middle hepatic vein(MHV) and without main MHV on the regeneration of liver transplantation. Methods 25 pair of donors and receptors of liver transplantation were divided in to two groups:with M HV group (group A, n= 14) and without main MHV (group B, n=11). The volumes of Ⅴ and Ⅷ segments of liver were measured in donors presurgicaUy,half month and 3 month in receptors postsurgically, the rates of regeneration of the Ⅴ and Ⅷ segment were calculated half month and 3 months postsurgically and compared between two groups. Results In group A,the regenerate rates of the Ⅴ,Ⅷ segment were 0.360±0.043 and 0.853±0.059 half month after surgery,0.253±0.043 and 0.708±0.059 three months after surgery respectively. In group B, the regenerate rates of the Ⅴ,Ⅷ segment were 0.306±0.049 and 0.815±0.066, respectively half month after graft, 0.161±0.049 and 0.627±0.066, respectively three months after surgery. There were no statistically significant differences in regenerate rates of the Ⅴ, Ⅷ segment of graft be-tween the two groups (P= 0.685 ,P>0.05 and P= 0.738, P>0.05). Conclusion The right lobe living donor liver transplantation, maintaining the MHV or reconstruct MHV tributaries without MHV has similar effects on the regeneration of Ⅴ,Ⅷ segment of graft.

Background:Tuberculosis (TB) is one of the most debilitating diseases worldwide.Current studies have shown that vitamin D plays a significant role in host immune defense against Mycobacterium tuberculosis,but clinical trials reported inconsistent results.Therefore,we systematically reviewed the literature to investigate whether vitamin D supplementation could improve the effect of anti-TB therapy.Methods:We systematically searched PubMed,Embase,and the Cochrane Central Register of Controlled Trials from their inception to February 8th,2019 for randomized controlled trials on vitamin D supplementation in patients with pulmonary TB receiving anti-TB therapy.The primary outcomes were time to sputum culture and smear conversion and proportion of participants with negative sputum culture.The secondary outcomes were clinical response to treatment and adverse events.A random-effects model was used to pool studies.Data were analyzed using RevMan 5.3 software.Results:Five studies with a total of 1126 participants were included in our meta-analysis.Vitamin D supplementation did not shorten the time to sputum culture and smear conversion (hazard ratio [HR] 1.04,95％ confidence interval [CI] 0.89-1.23,P =0.60;HR 1.15,95％ CI 0.93-1.41,P =0.20,respectively) and did not lead to an increase in the proportion of participants with negative sputum culture (relative risk [RR] 1.04,95％ CI 0.97-1.11,P =0.32).However,it reduced the time to sputum culture conversion in the sub-group of participants with TaqI tt genotype (HR 8.09,95 ％ CI 1.39-47.09,P =0.02) and improved the multidrug-resistant (MDR) TB sputum culture conversion rate (RR 2.40,95 ％ CI 1.11-5.18,P =0.03).There was no influence on secondary outcomes.Conclusions:Vitamin D supplementation had no beneficial effect on anti-TB treatment,but it reduced the time to sputum culture conversion in participants with tt genotype of the TaqI vitamin D receptor gene polymorphism and improved the MDR TB sputum culture conversion rate.

OBJECTIVETo compare the clinical efficacy difference between electroacupuncture (EA) at qijie area combined with spine balance-regulating massage and medication for posterior circulation ischemia (PCI).

METHODSOne hundred cases of PCI were randomly divided into a treatment group (50 cases) and a medication group (50 cases). The treatment group was treated with EA at Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Shenshu (BL 23), Danzhong (CV 17), etc. in qijie area combined with spine muscle-relieving massage and comprehensive chiropractic. The medication group was treated with oral administration of nimodipine (30 mg per time, three treatments per day) and vinpocetine injection with 500 mL of glucose injection or intravenous drip of 500 mL 0.9% sodium chloride injection, once a day. Ten treatments were taken as one course in both groups, and two courses were given. The symptom score, mean resistance index (RI) of vertebral artery (VA) and basilar artery (BA), mean velocity of blood flow (Vm) and comprehensive clinical efficacy were compared before and after treatment in two groups.

RESULTSThe cured and markedly effective rate was 79.6% (39/49) in the treatment group, which was superior to 54.7% (23/42) in the medication group (P<0.05). The symptom score was both significantly improved after treatment in two groups (both P<0.05), which was more obvious in the treatment group (P<0.05). The RI of VA and BA, Vm of VA and BA were significantly improved after treatment in two groups (all P<0.05), which were more obvious in the treatment group (all P<0.05).

CONCLUSIONThe electroacupuncture combined with spine balance-regulating massage has superior effect on improving mean velocity of blood flow and resistance index of vertebral artery and basilar artery as well as symptom score to medication, and is believed to be a safe and effective treatment for posterior circulation ischemia.

In this study, the induction of hairy roots of Bupleurum chinense DC. was explored and established after experiments at different conditions: A. rhizogenes A4 was used to infect the leaves bases of B. chinense tube seedlings. The explants were co-cultured on Phytagel-solidified media for 3 days and then, were turned into solid media, similar with the co-culture media except that bacteriostat was added. After 10 days, rootlets began to appear and after 4 to 5 weeks, rootlets can be converted into liquid shaking culture stage. Plants regeneration from hairy root was useful for the research of new germplasm production and the variety improvement breeding. In the present study, the regenerated plants were obtained. One approach was to continuously culture under light conditions the seedlings which parting off spontaneously from the hairy roots during liquid shaking culture. The other approach was to culture the callus-like tissues produced by hairy roots with the optimized regeneration media for the induction of regenerated plants. The results of present study provide a technique to induce hairy roots and plantlet regeneration of B. chinense and this technique is helpful for the researches on metabolism, especially on the Agrobacterium-mediated genetic transformation of B. chinense.
