Objective To find out the risk factors of postoperative low cardiac output syndrome(LCOS) of patients undergoing cardiac valvular surgery in ICU in order to provide basic for prevention and control measures.Methods Ninety-six valve replacement patients with valvular heart disease were enrolled as our subjects and they were hospitalized in ICU of the First People's hospital of Yichang from Jan.2008 to May.2013.The patients postoperative LCOS (Dopamine ＞ 10 μg/(kg · min)) were served as observation group (n =41),and the other were control groups(n =55).All data of the patients were recorded.Non-conditions Logistic regressions analysis were adopted to analyze the independent risk factors which resulted in LCOS undergoing cardiac valvular surgery.Results Of 96 patients undergoing cardiac vavular surgery,41cases (42.7％) had postoperative LCOS.Single factor analysis showed that hepatomegaly (P =0.007),course of diseases ≥ 15 years (P =0.042),cardiopulmonary bypass ≥ 120 min (x2 =3.937,P =0.047),pre-operative cardiac function ≥ Ⅲ degree (P =0.003) were the independent risk factors of postoperative LCOS undergoing cardiac valvular surgery.The Logistic multi factor regression analysis showed that the independent risk factors of postoperative LCOS undergoing cardiac valvular surgery included course of diseases ≥ 15 years (OR =2.825,95％ CI =(1.015-7.861)),Pre-operative cardiac function ≥ Ⅲ degree (OR =7.306,95％ CI =(2.050-26.035),P=0.002).Conclusion Course of diseases ≥15 years and Pre-operative cardiac function≥ Ⅲ-Ⅳ degree are the independent risk factors of LCOS undergoing cardiac valvular surgery.

Objective To analyze the differential proteomics of ASMC stimulated by wild IL-13 and mutant IL-13 and to investigate the relations of protein profiles of ASMC to asthma and possible targets for the treatment of bronchial asthma.Methods The total proteins of ASMC stimulated by wild IL-13 and mutant IL-13 were separated by immobilized pH gradient(IPG)-based 2-DE and the differentially expressed protein spots were identified by matrix assisted laser desorption-time of flight mass spectrometry(MALDI-TOF-MS). Results The 2-DE detected approximately(840?21)spots on wild IL-13 samples and(892?17)spots on mutant IL-13 samples(n=3)and(685?19)spots matched.Six significantly differential proteins were subjected to MALDI-TOF-MS analysis and three of them were identified as stathmin 1,Ribosomal protein p~0 and NADH dehydrogenase.Conclusions ASMCs stimulated by wild IL-13 and mutant IL-13 present different proteomic profiles that may shed some light on the mechanism for the asthma causing effect of wild IL-13 and mutant IL-13.

OBJECTIVETo detect the effect of genistein on mandible metabolism in ovariectomized rats.

METHODSForty 12 week-old female SD rats were randomly assigned to four groups: (1) sham operated; (2) ovariectomized; (3) ovariectomized and treated with estradiol; (4) ovariectomized and received genistein, 45 mg/kg body weight per day. After 12 weeks, bone mineral density (BMD), serum level of alkaline phosphatase (ALP), acid phosphatase (ACP), osteocalcin, IL-1beta, TNF-alpha, IL-6 and calcitonin (CT) were evaluated. In addition, the serum estradiol and the weight of uteri were also examined to indicate the side effect of genistein to the uteri.

RESULTSOvariectomized animals had a significant decrease in BMD, and increased serum level of ALP, ACP, IL-1beta and osteocalcin compared with sham rats. After treated with genistein, BMD and the serum level of ALP, ACP, osteocalcin increased significantly, while the serum level of IL-1beta and TNF-alpha decreased. Especially, the increase of ALP and osteocalcin was higher than that of estradiol-treated animal. Additionally, the uterus weight index and the serum estradiol in genistein-treated rats were lower significantly than those of estradiol-treated rats.

CONCLUSIONSGenistein can improve the mandible bone metabolism as well as its effect on femur through the promotion of bone formation and the prevention of bone resorption with slight side effect. Genistein provides an additional viable way to therapy for osteoporosis in the jaw bones.

Objective To understand the pathogenesis of primary hypothyroidism associated with polymyositis-like syndrome.Method Four cases were presented and the clinical characteristics were analyzed.Results All of the four patients were male.Complaints of weakness primarily affecting proximal muscles and elevation of muscle enzymes were presented.Primary hypothyroidism was diagnosed after clinical examination.Complaints of weakness and the elevated muscle enzymes were all improved after the substitution of thyroxine.Conclusion Hypothyroidism could cause polymyositis-like syndrome,and thyroid function should be screened when elevation of muscle enzymes is presented.

OBJECTIVETo explore the effects of stromal interaction molecule 1 (STIM1) on the expression of apoptosis-related proteins in prostate cancer PC-3 cells.

METHODSWe transfected the lentivirus vector STIM1-pGCSIL-GFP carrying STIM shRNA into human hormone-independent prostate cancer PC-3 cells, and 3 days later observed the transfection efficiency by fluorescence microscopy. At 7 days after transfection, we determined the expression of STIM1 in the PC-3 cells by RT-PCR and Western blot and those of apoptosis-related proteins Bcl-2, Bax, survivin and activated Caspase-3 by Western blot.

RESULTSAt 3 days, inverted microscopy revealed a transfection efficiency of > 80%. At 7 days, the STIM1 expression was significantly inhibited at both mRNA and protein levels. The Bcl-2/Bax rate was remarkably decreased as compared with that of the control group (0. 31 vs 1.24 ) , and the survivin expression was markedly reduced, 0. 14 times that of the relative expression in the control. However, the Caspase-3 cleavage was significantly activated, 1.52 times that of the control (P <0.05).

CONCLUSIONSTIM1 can be regarded as an oncogene in prostate cancer PC-3 cells. Inhibition of its expression can induce PC-3 cell apoptosis by reducing the Bcl-2/Bax rate, decreasing the survivin expression, and activating the Caspase-3 pathway.

BACKGROUND: Stellate ganglion block has the ability to improve the imbalance of the autonomic nervous system in perimenopausal syndrome. Lumbosacral plexus is an automatic nervous block, and exerts similar effects with stellate ganglion block. OBJECTIVE: To investigate the effect of lumbosacral plexus block on the serum level of hormones and histology of the ovary in rabbits, thus providing a new treatment strategy for perimenopausal syndrome. METHODS: This was a randomized controlled animal experiment, which was finished at the Animal Center of Guiyang Medical Unversity, China. The healthy rabbits were randomly divided into experimental and control groups, and underwent lumbosacral plexus block by injecting 0.5 mg of vitamin B12, 100 mg of lidocaine and 10 mL of normal saline into the psoas compartment, and the same volume of normal saline, respectively. The effect of lumbosacral plexus block on the serum levels of hormones (estradiol, gonadotropin releasing hormone, follicle-stimulating hormone and luteinizing hormone) at rabbit proestrus, estrus and metaestrus were observed, respectively. The pathological changes of the ovary in a complete estrus cycle were observed. The relationship between the treatment time of lumbosacral plexus block and the levels of hormones was investigated after 1, 3 and 6 complete estrus cycles. The experimental followed the national guidelines for the Care and Use of Laboratory Animals, and Consensus author guidelines on animal ethics and welfare by the International Association for Veterinary Editors (IAVE), and prepared in accordance with the Animal Research: Reporting of In Vivo Experiments Guidelines (ARRIVE Guidelines). RESULTS AND CONCLUSION: Lumbosacral plexus block can increase the serum level of estrogen, reduce the serum levels of follicle-stimulating hormone and luteinizing hormone, and regulate the hypothalamic-pituitary-ovary axis function. Presumably, it may be used as a treatment method or adjuvant therapy of perimenopausal syndrome. Future experiments are needed to explore the effect of lumbosacral plexus block on the serum levels of hormones in a rabbit after oophorectomy to determine whether it exhibits the same effect on ovarian failure.

ObjectiveTo investigate the changes of non-linear dynamics characteristic of EEG in patient with acute cerebral stroke under eyes closed state. MethodsEEG were recorded in 31 patients with acute cerebral infarction and 22 healthy volunteers under eyes closed state. Correlation dimension (D2) and Approximate Entropy (ApEn) were calculated for all subjects. ResultsD2 and ApEn of uninjured forehead cortex (FP1,FP2)reduced significantly in the group of cerebral infarction as compared with the group of normal control at eyes closed state. ConclusionDynamic analysis based on D2 and ApEn topographic maps might be helpful in understand the changes of mental functions after stroke, that can be used in the study of mental function.
