Objective To investigate the clinical intervention effect of superficial needling at point Fenglong on gastroscopy side reaction.Methods Eighty-two gastroscopy patients were randomly allocated to treatment and control groups, 40 cases each. The treatment group received gastroscopy and superficial needling at point Fenglong, and the control group, gastroscopy and sham acupuncture at point Fenglong. The pain score and the incidence of nausea and vomiting were observed in the two groups during gastroscopy.Results There was a statistically significant difference in the pain score between the two groups (P<0.05). The incidence of nausea and vomiting was 31.7% in the treatment group and 65.9% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Superficial needling at point Fenglong can effectively reduce the incidence of gastroscopy side reaction.

Objective To investigate the clinical effect of laparoscopy combined with leuprolide on patients with mild endometriosis and infertility and effects on fertility function of patients. Methods A total of 60 patients with mild endometriosis and infertility in our hospital were randomly divided into the control group (n=30) and the observation group (n=30). The control group was treated with laparoscopic surgery, the observation group was treated with leuprorelin treatment, and the levels of FSH, E2, luteinizing hormone and PROG were tested by automatic biochemical analyzer between two groups before and after treatment, the pregnancy rate as assessment of reproductive function in patients. Clinical curative effect and effect on fertility of 2 groups were compared. Results Levels of FSH, E2, LH and PROG in the observation group were lower than those in the control group (P<0.05) in 3 months after treatment, and the pregnancy rates in the observation group after 1 months, 2 months and 3 months were higher than that in the control group (P<0.05). Conclusion The treatment of Laparoscopy combined with Leuprolide for mild endometriosis and infertility in patients has ideal effect, and is worthy of popularization and application.

ObjectiveTo investigate the effects of HIF-1α,on mitochondrial function of cardiomyocytes stimulated by lipopolysaccharide (LPS).MethodsCultured neonatal cardiomyocytes were randomly (random number) distributed to four groups (n =5).Control group:the neonatal cardiomyocytes were cultured in normal condition without any treatmeat; LPS group:cardiomyocytes were exposed to 1 μg/ml LPS for 2 h; YC-1 + LPS group:cardiomyocytes were exposed to 4 μmol/L YC-1 for 8 h before LPS treatment; YC-1 group:cardiomyocytes were exposed to 4μmol/L YC-1 for 8 h.As indexes of mitochondrial function,MMP,the content of ATP and the activity of cytochrome oxidase were measured,COX1/2 protein expression was determined by Western blotting.Results Compared with control group,LPS decreased MMP,the content of ATP and the activity of COX obviously ( P ＜0.05 ),depressed the expression of COX- 1 protein ( P ＜ 0.05 ),induced the expression of COX-2 protein ( P ＜ 0.05 ).Compared with the LPS group,MMP,the content of ATP and the activity of COX were markedly attenuated ( P ＜ 0.01 ),the expression of COX-1 was significantly increased and the expression of COX-2 was decreased in theYC-1 +LPS group (P ＜ 0.01 ).ConclusionsYC-1 attributes to the dysfunction of mitochondrial of myocyte by alterating the expression of COX-1 and 2, HIF-1α may attenuate the mitochondrial dysfunction of cadiomyocytes stimulated by LPS.

Objective To explore the relation among depression,hopelessness and suicide risk,as well as the mediating effect of hopelessness between depression and suicide risk.Methods 1 381 students were recruited from five junior middle schools in Linyi by using cluster random sampling.They were investigated with General Situation Questionnaire,Scale for Suicide Ideation(SSI),Beck Hopelessness Scale (BHS) and Beck Depression Iventory (BDI).Results Suicide risk in junior middle school was significant positively correlated with depression and hopelessness (r=0.43 and 0.64 respectively,P＜0.01).Hopelessness partly mediated the relationship between depression and suicide risk (55.8％).Furthermore,hopelessness showed partial mediating effect on the relationship between depression and suicide risk in boys (42.7％) and in 7th Grade students (29.9％),and also complete mediating effect in girls (74.1％) and in 8th Grade students (95.3％).Conclusion The suicide risk in middle school students increase with the increasing of the severity of depression and hopelessness.The hopelessness plays different mediating effects on relation between depression and suicide risk in students with different gender and grade.

The changes of erythrocytic membrane band 3 protein and intraery-throcytic and extrar rythrccytic gases and electrolytes were studied in 69 cases of cor pulmonale and 50 normal subjects.It was found that in the patients of cor pulmonale accompanied with type Ⅱ respiratory failure,the relative low level of erythrocytic membrane band 3 protein and the restriction of HCO-3/Cl-exchange were the factors to aggravate CO2 retention and respiratory acidosis,relative intraerythrocytic alkalosis resulted from the relative increase of intra-erythrocytic HCO-3([HCO-3]),and prompt adminstration of oxygen to cor pulmonale patients with hypoxemia could not only improve extraerythrocytic acid-base imbalance but also increase intraerythcocytic P5O2 and the tissue capacity to store oxygen.

AIM: To investigate the relationship between alteration of CHOP/GADD153 protein expression and cardiomyocyte apoptosis induced by angiotensin Ⅱ (AngⅡ), and inhibitory effects of CHOP/GADD153 antisense oligodeoxynucleotide (anti-ODN) on apoptosis in vitro.METHODS: Cultured neonatal cardiomyocytes were exposed to AngⅡ with or without preincubation of CHOP/GADD153 anti-ODN. Variability of myocytes was measured by MTT assay, the lactate dehydrogenase (LDH) release was also detected, the percentage of annexin V positive myocytes was monitored by flow cytometry as apoptosis rate, CHOP/GADD153, Bcl-2 and Bax expressions were determined by Western blotting.

AIM： To evaluate the role of Na＋/H＋ exchanger-1（NHE-1）in the proliferation and apoptosis of pulmonary artery smooth muscle cells in rats. METHODS: Twenty Wistar rats were equally randomized into the control group and 3-week hypoxic group. Intracellular pH (pHi) of the smooth muscle was determined with fluorescence measurement of the pH-sensitive dye BCECF-AM and the expression of NHE-1 mRNA was detected with RT-PCR. The primary culture of pulmonary artery smooth muscle cell in vitro was performed. In situ cell death detection kit (TUNEL) was used to study the effect of specific NHE-1 inhibitor, dimethyl amiloride (DMA), on the apoptosis of muscle cells which had intracellular acidification. RESULTS: pHi value and expression of NHE-1 mRNA of pulmonary artery smooth muscle cell were significantly higher respectively in the hypoxic group than those in the control group (P＜0.01). DMA elevated the apoptotic ratio significantly. The effect was enhanced when DMA concentration was augmented and the time was prolonged. CONCLUSION： With the function of adjusting pHi, NHE-1 may play an important role in the proliferation and apoptosis of pulmonary artery smooth muscle cells.
