0.05).Conclusion The expression of TM in different TCM syndromes of gastric carcinoma was different.There exists a certain relation in the expression of TM1 and TM2 in different TCM syndromes of gastric cancer.

0.05).The recurrence of pterygium was related to the age.If the age increased five years,the risk of recurrence decreased 18.1%. Conclusion The application of MMC(during) the operation could decrease the recurrence rate of pterygium.The recurrence rate of pterygium was not related to the time of application of 0.02% MMC,and detainment for 3 min was enough during the operation.

Objective To study the prospective memory and the severity of the impairment of event- based prospective memory(EBPM)and time-based prospective memory(TBPM)in normally aging adults. Methods We set a neuropsychological battery to measure the education-matched 40 adults and 40 normally aging adults who were given EBPM and TBPM tasks.Results Compared with the young controls(EBPM, 6.25?1.60;TBPM,5.38?0.87),both EBPM(2.50?0.85)and TBPM(4.93?1.07)in the elderly had been impaired,especially EBPM(t = 13.117,P

Objective To investigate the effect and mechanism of hydrogen saline on oxidative stress damage in rats brain tissues after cardiopulmonary resuscitation (CPR). Methods Eighteen adult male pathogen-free Sprague-Dawley (SD) rats were randomly divided into control group (Con group), conventional resuscitation group (ROSC group) and hydrogen saline treatment group (ROSC+HRS group), with 6 rats in each group. All rats were asphyxiated by tracheal clip method to establish cardiac arrest (CA) model, and received first aid with CPR, electric defibrillation and adrenaline until return of spontaneous circulation (ROSC). The rats in ROSC+HRS group were intraperitoneally injected with 2% hydrogen saline (5 mL/kg for the first time and 3 mL/kg every 2 hours). The rats in Con group were only tracheal intubated and mechanical ventilated. The rats were sacrificed after ROSC for 12 hours, and the brain tissue was harvested to determine the contents of malonaldehyde (MDA), superoxide dismutase (SOD), and catalase (CAT). The protein expression of heme oxygenase-1 (HO-1) was determined with Western Blot, and the mRNA expression of HO-1 was determined with reverse transcription-polymerase chain reaction (RT-PCR). Results Compared with the Con group, the MDA was significantly elevated in ROSC group (nmol/mg: 8.15±0.11 vs. 3.68±0.16, P < 0.05), the SOD and CAT were significantly decreased [SOD (U/mg): 69.30±2.39 vs. 94.65±2.75, CAT (U/mg): 74.38±1.65 vs. 95.68±1.88, both P < 0.05], HO-1 mRNA expression was significantly elevated (gray value: 1.383±0.194 vs. 1.117±0.083, P < 0.05), and HO-1 protein expression showed no significant change (gray value: 0.350±0.049 vs. 0.175±0.026, P > 0.05). Compared with the ROSC group, the MDA was significantly decreased in ROSC+HRS group (nmol/mg: 4.72±0.28 vs. 8.15±0.11, P < 0.05), the SOD and CAT were significantly elevated [SOD (U/mg): 83.02±1.10 vs. 69.30±2.39, CAT (U/mg): 85.07±1.94 vs. 74.38±1.65, both P < 0.05], HO-1 mRNA expression was significantly elevated (gray value: 3.200±0.200 vs. 1.383±0.194, P < 0.05), and the HO-1 protein expression was significantly elevated (gray value: 0.788±0.059 vs. 0.350±0.049, P < 0.05). Conclusions Oxidative stress damage is an important mechanism of CPR brain damage. Hydrogen saline can increase the expression of HO-1 in brain tissue, and decrease oxidative stress damage of brain after CPR.

OBJECTIVETo investigate the factors influencing the pregnancy outcomes of artificial insemination with donor sperm (AID), improve the pregnancy rate, and evaluate the safety of the offspring.

METHODSWe retrospectively analyzed 7,761 cycles of AID for 5,109 infertile couples performed between July 1, 2005 and June 30, 2013 in the Center of Reproductive Medicine of Shenyang No 204 Hospital, the outcomes of pregnancy, and the incidence of birth defects.

RESULTSTotally, 2 252 clinical pregnancies were achieved by AID, in which the pregnancy rate per cycle was 29. 02% and the cumulative pregnancy rate was 44. 08%. The clinical pregnancy rate was remarkably higher in the females of ≤ 35 years than in those of > 35 years old (30.31% vs 20.18%, P < 0.01), in the women with < 5-year infertility than in those with > 5-year infertility (30.83% vs 28.16%, P < 0.01), and in the patients of the ovarian stimulation group than in those of the natural cycle group (33.22% vs 28.68%, P < 0.01) The clinical pregnancy rate was the highest in the first treatment cycle (29.87%), with statistically significant difference from the fourth cycle (23.61%) (P < 0.05), but not between the other cycles (P > 0.05). There were 28 cases of birth defects in the offspring (1.40%), including 6 cases (21.43%) involving the cardiovascular system, 4 (14.29%) involving the musculoskeletal system, 3 (10.71%) involving the urogenital system, 3 (10.71%) involving the central nervous system, 2 cases (7.14%) of cleft lip and palate, 2 (7.14%) involving the respiratory system, 2 (7.14%) involving the gastrointestinal digestive system, and other anomalies.

CONCLUSIONFemale age, infertility duration, and ovarian stimulation treatment are important factors influencing the clinical pregnancy rate of AID. Artificial insemination with cryopreserved donor sperm does not increase the incidence of birth defects, which is considered as a relatively safe technique of assisted reproduction.

OBJECTIVETo study the therapeutic mechanism of Zhizhu Pill (ZP) for treating functional dyspepsia (FD) rats.

METHODSTotally 30 ten-day-old male rats were randomly divided into the normal control group (n =10) and the model group (n = 20). The FD rat model was induced using gastric administration of 0.1% iodoacetamide (IA) combined tail clamping. The model was evaluated when rats were 8-week old. Successfully modeled rats were randomly divided into the model group (n = 10) and the ZP group (n = 10). Rats in the normal group and the model group were administered with normal saline by gastrogavage, while those in the ZP group were administered with ZP Decoction (2 mL/100 g) by gastrogavage. All medication lasted for 7 successive days. The contractile activity in in vitro longitudinal gastric muscle was recorded using Power Lab biological signal collecting system. The expression of growth hormone secretagogue receptor (GHSR) in stomach of FD rats was detected using Western blot and immunohistochemistry (IHC).

RESULTSCompared with the normal group, average frequencies of gastric contraction and changing rates of amplitude obviously decreased in the model group (P < 0.05). Results of Western blot and IHC showed that the expression of GHSR decreased in the model group (P < 0.01). Compared with the model group, average frequencies of gastric contraction and changing rates of amplitude obviously increased in the ZP group (P < 0.05). Results of Western blot and IHC showed that the expression of GHSR increased in the ZP group (P < 0.01).

CONCLUSIONZP could promote the gastric motility in FD rats induced by gastric administration of IA combined tail clamping, and its mechanism might be related to up-regulating GHSR protein level.

OBJCETIVETo investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro.

METHODSFrom October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells.

RESULTSThe number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs.

CONCLUSIONIt was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.
