Objective To investigate the interrelationship between Golgi phosphoprotein 3 ( GOLPH3 ) expression with vasculoar endothelial growth factor( VEGF) expression in the progression of human gastric cancer by detecting the expression level of GOLPH3 and VEGF. Methods Immunohistochemistry ( IHC) was used to detect the ex-pression of GOLPH3 and VEGF in 55 cases of gastric cancerous and carcinoma-adjacent tissues. Pearson correlation analysis was used to discuss the association between GOLPH3 expression with VEGF expression. Results The im-munohistochemical detection showed that the positive expression rates of GOLPH3 and VEGF were 67. 27%, 58. 18% respectively, which were significantly higher than the positive expression rates in carcinoma-adjacent tis-sues ( P<0. 05 ) . A statistical analysis revealed that the positive expression rate of GOLPH3 and VEGF in the gas-tric cancer tissues were strongly correlated with depth of invasion ( P<0. 05 ) , distant metastasis ( P<0. 01 ) and TNM stages (P<0. 01), whereas it did not significantly correlate with age or gender or size of tumor. Compared with the negative for the GOLPH3 expression, the VEGF expression in gastric cancer tissues positive for the GOL-PH3 expression was significantly higher. The protein level of GOLPH3 expression was positively correlated with VEGF expression (r=0. 508,P<0. 01). Conclusion GOLPH3 overexpression may regulate gastric angiogenesis by upregulating the expression of VEGF, which affects the invasion and metastasis of gastric cancer.

Objective To investigate the possible pathogenic mechanisms of narrow pharynx in obstructive sleep apnea syndrome (OSAS) induced by neurogenic inflammation Methods The levels of nitric oxide (NO) and calcitonin gene related peptide (CGRP) in fasting plasma and pharyngeal soft tissue homogenate from mild, moderate, and severe OSAS patients, the normal controls, and patients undergoing uvulopalatopharyngoplasty (UPPP) were detected by immunoradioassay and enzyme reduction Results Plasma NO level in serious OSAS patients was the lowest in the five groups and that in the control group was the highest [severe OSAS=(53 33?7 83) mmol/L, controls=(74 30?6 40) mmol/L, UPPP group=(68 12?7 46) mmol/L, moderate OSAS=(60 45?7 51) mmol/L, mild OSAS=(69 24?6 32) mmol/L, P 0 05) [severe OSAS =(44 18?5 80) mmol/L, moderate OSAS=(48 04?6 66), mild OSAS=(50 72?5 33) mmol/L, controls =(54 37?4 43) mmol/L, UPPP group =(54 10?3 70) mmol/L] NO level in pharyngeal tissue of OSAS increased significantly [OSAS =(0 748?0 053) ?mol/g, controls=(0 382?0 031) ?mol/g, P

Objective To evaluate the efficacy and safety of argatroban versus aspirin plus clopidogrel in the treatment of acute ischemic stroke. Methods Seventy five patients with acute ischemic stroke within 48h of symptom onset were randomly divided into two groups: argatroban group (argatroban was used for 7 days according to the instructions, followed by aspirin 100mg per day plus clopidogrel 75mg per day until discharge, n=35), and combination antiplatelet group (300mg of clopidogrel for the first day, then 75mg daily plus aspirin 100mg daily until discharge, n=40). Oxfordshire Community Stroke Project (OCSP) classification was assessed in patients before treatment. National Institutes of Health Stroke Scale (NIHSS) was used for rating neurological deficit score of patients, and Barthel index for rating activities of daily life (ADL), and modified Rankin scale for handicap score. NIHSS was assessed one week after enrollment, while ADL and mRS assessment were recorded 3 months after onset. Brain imaging, liver and kidney function, blood routine tests and blood coagulation capacity of the patients were measured before and one week after enrollment to observe changes in hemorrhage and biochemical indicators. Drugs-related adverse events were recorded during treatment. All patients received TOAST analysis before leaving hospital. Results 1. In both groups, NIHSS was reduced after oneweek treatment, compared with that before treatment, while ADL was improved at three-month follow-up, compared with those at admission. The results showed statistically significant difference (P<0.01) in each group, but no significant difference (P>0.05) was found between two groups. The transient ischemic attacks (TIA) disappeared in both groups. Brain imaging showed that in three patients the lesion advanced to infarction in argatroban group (total 6 patients), and two patients in the combined antiplatelet group (total 5 patients) suffered from the same change. 2. The brain imaging and measuring of relevant laboratory indicators of patients in both groups were performed again after one-week treatment. There was no bleeding events (including intracranial hemorrhage and hemorrhage in other organs) or impairment of hepatorenal function (P>0.05). 3. In both groups, OCSP classifications of patients were mainly divided into the partial anterior circulation infarction (PACI), lacunar infarction (LACI) and posterior circulation infarction (POCI), while TOAST etiological analyses of patients were mainly large-artery atherosclerosis (LAA) and small artery occlusion (SAO). In both groups, the neurological defects were improved after treatment, and there was no significant bleeding events during treatment period. There was no significant difference of NIHSS one week after enrollment between PACI subgroups (P>0.05), while better neurological improvement was showed in the POCI subgroup of argatroban group. Conclusions Argatroban anticoagulant and combination antiplatelet therapy with aspirin plus clopidogrel can effectively improve neurological deficit of patients, reduce recurrence rate and deterioration of the illness in acute phase, and improve patients' daily activities (ADL). Argatroban therapy showed better neurological function improvement in the posterior circulation infarction patients. As a new anticoagulant drug, argatroban is safe in the treatment of acute ischemic stroke. For the patients who have infarction involving the posterior circulation, argatroban, as a more aggressive treatment, should be recommended. (The trial registered number: ChiCTR TRC-13003384)

OBJECTIVETo explore the underwater decompression schedule for 100 m Trimix conventional diving operations and evaluate its safety through a simulated rabbits Trimix conventional diving.

METHODSAccording to the Haldane theory, the assumed time units, the classification of tissue compartments, the nitrogen super-saturation safety coefficient and the selection of methods used for the calculation of the simulated 100 m Trimix conventional diving schedule were properly selected, and the calculating method for the dive decompression schedule was thus firmly established. In our experiments, five tissue compartments were selected during the calculation of decompression schedule: 5 min, 10 min, 20 min, 40 min and 75 min, and the nitrogen super-saturation safety coefficient was calculated by 1.6. Eight New Zealand rabbits were performed a simulated 100 m Trimix dive program which was established according to the Haldane theory, and eight rabbits for intact group. The tissues wet/dry ratio and ethology were detected and observed before and after the simulated diving to evaluate the safety of decompression schedule.

RESULTSBy using the developed underwater decompression schedule, abnormal ethology changes in rabbits could not be observed after compression and decompression to the surface; and the tissues wet/dry ratio of simulated diving rabbits had no significant changes compared with the intact group (P > 0.05).

CONCLUSIONThe decompression schedule calculated by Haldane theory seemed to be safe and reliable, the diving breathing gas concentration did not cause oxygen toxicity and nitrogen narcosis among the dive rabbits, and dive efficiency was greatly improved by using enriched oxygen gas in UPTD safety range during decompression.

To explore the population composition and the morbidities and treatment of hypertension and diabetes mellitus among the patients at 4 community healthy service stations at Gaobeidian,Chaoyang District of Beijing during the period of February 2009 to October 2010.A cross-sectional survey was conducted by self-reporting questionnaires.Most patients were above 40 years old,had a lower income level and education status and their treatment costs were mainly covered by social health insurance.Their incidences of hypertension and diabetes mellitus were high.Though most of them could recognize and treat their illnesses,the control rate remained non-satisfactory.Targeting incoming patients,community health service stations should take its advantages of managing chronic diseases and enroll more patients from local communities.

The primary aim of this research is to systematically sort out and analyze available clinical documents for chronic congestive heart failure in traditional Chinese medicine (TCM) and integrated traditional Chinese and Western medicine, and to explore the diagnosis and treatment rule of TCM syndrome factors with data mining method.

Objective To explore the efficacy of long- and short-acting triptorelin on pituitary down-regulation in long protocol and the pregnancy outcome in vitro fertilization and embryo transfer (IVF-ET) . Methods Three hundred and seventeen patients for IVF-ET were enrolled as study and randomized them into two groups. In group A (n=145), patients received single dose subcutaneous injection of 1.25 mg long-acting diphereline in mid-luteal phase. In group B (n=172), patients received 0.1 mg/d subcutaneous injection of short-acting diphereline in mid-luteal phase for 14-18 days until pituitary suppression were got,and then reduced to 0.05 mg/d until the injection of HCG. Results The dose and the days of gonadotropin administration in group A were bigger and longer than those in group B ( <0.05) . There were no significant differences in the number of retrieved oocytes, fertilization rate,high quality embryos,implantation rate and clinical pregnancy rate between the two groups (all > 0.05) . But clinical pregnancy rate of group B had increasing trend. Conclusion Administration of short-acting diphereline has the similar effect with that of long-acting diphereline on pituitary down-regulation in long protocol. Short-acting diphereline requires lower amount of gonadotropin and is more flexible,so it should be recommended.
