Today,more and more patients with diabetes are requiring surgical intervention.Not only the metabolic disturbance of carbohydrate will be aggravated by surgical stress,but also the risk of perioperative complications and mortality have been greatly increased in patients with diabetes.Therefore,a complete preoperative assessment and blood glucose management of preoperative,intraoperative,and postoperative periods are needed to get full assurance for diabetic patients to undergo surgery and to pass through the perioperative period smoothly.

Reflex sympathetic dystrophy after stroke,also called shoulder-hand syndrome(SHS),is a common complication of stroke.It is presumed that SHS is consequence of many factors,including periphery injury,effect of sympathetic never system,neurogenic inflammation,and plasticity of central nervous system.

Objective To evaluate the effect of maternal separation stress on the behavior of neonatal rd mice.Methods Neonatal rd mice were divided into maternal separation (MS) group (n=9) and control group (n=9).MS-stress was induced in the MS group by 4-hour-separation per day for 28 days.Open field test,elevated plus maze test,forced swim test and tail suspension test were used to evaluate the anxiety-like and depression-like behavior of the neonatal rd mice.Results The stay time and distance travelled of MS group in the central zone were 0.88％ and 28.17±5.65 cm,respectively,significantly shorter than that of the control group (2.61％,109.9±9.79 cm.P =0.04,P =0.001).Compared with the control group,the stay time in open arms of the MS group was significantly decreased (P<0.01),while the immobility time in forced swim test and tail suspension test of the MS group were 126.5±10.22 s and 21.56±6.83 s,significantly longer than that of the control group (77.75±16.83 s,P =0.02,7.37±3.22 s,P =0.03).Conclutions The 28-day maternal separation stress can significantly increase the anxiety-like and depression-like behavior in neonatal rd mice.

This study aimed to evaluate emerging trends of drug resistance to nucleoside reverse transcriptase inhibitors (NRTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs) among 290 former blood donor HIV-1 infected patients in Hubei,China,from 2004 to 2006,all of whom had received anti-HIV-1 therapy.The presence of NRTI- and NNRTI-associated mutations were established by sequencing; genotypic and predicted phenotypic drug resistance were evaluated using HIVdb Program version 5.0.1 (http://hivdb.stanford.edu/pages/algs/HIVdb.html).Genotypic drug resistance analysis showed significant increases in percentages of patients carrying HIV-1 strains with M41L,T215Y/F,D67N,K103N,G190A/S,Y181C/F or L210W mutations.Of the variants' predicted phenotypic drug resistance,highly significant increases were detected in percentages of patients carrying HIV-1 with high resistance to zidovudine (AZT) or stavudine (D4T) in NRTIs,and to delavirdine (DLV),efavirenz (EFV) or nevirapine (NVP) in NNRTIs; intermediate resistance to abacavir (ABC),AZT,D4/T,didanosine (DDI) or tenofovir disoproxil fumarate (TDF) in NRTIs,and to etravirine (ETR) in NNRTIs; and low and potential low resistance to lamivudine (3TC),ABC,emtricitabine (FTC) or TDF in NRTIs,and to ETR in NNRTIs.

Heavy-ions have the similar characteristic of depth-dose distribution with protons, but exhibit enhanced physical and radiobiological benefits. With increasing development in technical and clinical research, more facilities are being installed in the world. At the same time, many critical techniques of heavy-ion therapy facility were optimized and completed. This paper classified and reviewed the basic structure of heavy-ion system equipments, especially the accelerator, gantry, nozzle , TPS.

Objective To investigate whether Tumor Necrosis Factor-alpha (TNFα) is capable of activating Rho kinase pathway which leads to smooth muscle cell proliferation and the intervention function of Rosuvastatin, and clarify the mechanism and intervention manner of anti-atherosclerosis by Rosuvastatin. Methods Wistar neonate rat smooth muscle cells were cultured, and the activity of cell proliferation was determined by methyl thiazolyl tetrazolium (MTT). The expression of Rho kinase genes after the stimulation of TNFα was evaluated by RT-PCR. Western blot method was used to measure the protein expression of proliferating cell nuclear antigen (PCNA) after TNFα stimulation and Rosuvastatin intervention in smooth muscle cell. Results The TNFα stimulation significantly enhanced the expression of Rho kinase and increased the expression of PCNA protein in smooth muscle cells (P < 0.05). These effects were positively correlated with prolonged treatment whereas additional Rosuvastatin administration inhibited the above-mentioned effects (P < 0.05). Conclusions The activation of TNFα mediated Rho kinase signaling pathway can significantly promote smooth muscle cell proliferation, and Rosuvastatin can not only inhibit this pathway but also the induced proliferation.

Objective To analyze the relationship and genetic diversity of Stemona tuberosa in different populations. Methods ISSR molecular technique was be used to decipher the genetic diversity of S. tuberosa in South of the Yangtze River, The genetic relationships among different populations were analyzed based on software POPGEN32 and the DNA molecular dendrogram was structured according to the software NTSYSpc-2.10E. Results Seventy-four obvious bands of different S. tuberosa populations were amplified with seven suitable ISSR primers, 74 of them were polymorphic sites, and the percentage of polymorphism bands reached to 100%; Effective number of alleles (Ne) is 1.524 4, the average Nei's genetic diversity (He) index is 0.314 6, the average Shannon's information index is 0.478 6, the genetic distance among populations is 0-0.950 2, and the average distance is 0.416 3. Conclusion The study revealed that a relative high genetic diversity occurred in different populations of S. tuberosa, the genetic variation is related to geographical distance in different populations of S. tuberosa. The study will throw light on how to introduce and cultivate traditional Chinese medicinal plant, how to screen peculiar pyrrolidine alkaloids from S. tuberosa, and how to build to scientific standards and theoretical basis for traditional geo-authentic crude drug in China.

ObjectiveTo observe the effect of early partial body weight support on walking ability for stroke patients with hemiplegia.Methods60 stroke patients were divided into 3 groups, receiving conventional early rehabilitation: group A (20 cases) received conventional rehabilitation for 8 weeks; group B (20 cases) received 2 weeks conventional rehabilitaion and 6 weeks partial body weight support; group C (20 cases) received 5 weeks conventional rehabilitaion and 3 weeks partial body weight support. Fugl-Meyer Assessment(FMA), Barther Index(BI) and Berg Balance Scale(BBS) were used to assess the effect before and after treatment.ResultsThe socres of FMA, BI and BBS improved in walking function after the treatment(P<0.05). Comparing with groups A and C, group B improved more significantly after treatment (P<0.05), and group C was better than group A (P<0.05). ConclusionPartial body weight support can improve walking function of hemiplegic patients at early stage.
