Objective:To compare the effects of different anesthesia methods on stress hormones and hemodynamic changes in the patients with gynecological laparoscopic surgery. Methods:Retrospective analysis was carried out. Totally 145 patients with gynecolog-ical laparoscopic surgery were divided into two groups according to the anesthesia method, the control group with 72 cases was given routine remifentanyl propofol intravenous anesthesia, and the observation group with 73 cases was given routine propofol isoflurane com-posite anesthesia. Such hemodynamic indices as SBP, DBP and HR, and plasma NE, E, cort and AT II levels at different time points in the two groups were studied and compared, and adverse drug reactions were also observed in the two groups. Results:The BP and HR at T2 and T3 time point in the two groups were significantly lower than those at T0 time point (P<0. 05), and those in the obser-vation group were lower than those in the control group at the same time point(P<0. 05). The levels of NE, E, cort and ATⅡat T2 and T3 time point in the two groups were significantly higher than those at T0 time point (P<0. 05), while the increase in the observa-tion group was lower than that in the control group (P<0. 05). The incidence of adverse drug reactions (ADR), such as respiratory depression, hypertension, bradycardia and so on, and the total incidence of ADR in the observation group were both lower than those in the control group (P<0. 05). Conclusion:Compared with remifentanyl propofol intravenous anesthesia, propofol isoflurane composite anesthesia can keep the hemodynamic stability more effectively and reduce the stress reaction with fewer ADR and promising safety, which is worthy of wider application in clinics.

Objective To research in correlations between occupational pressure,social support and subjective well-being,in order to explore effective ways to reduce the occupational pressure.Methods Nurses from a certain grade 2A hospital in Wuhan were selected as research objects.Questionnaires were used to investigate the correlations between occupational pressure,social support and subjective well-being.Results Nurses endured a high level burden.The subjective well-being of nurses was negatively correlated with occupational pressure,the higher the occupational pressure,the lower the subjective well-being.The subjective well-being of nurses was positively correlated with social support.The occupational pressure and social support could predict the subjective well-being of nurses.Conclusions There exists potential relationships between occupational pressure,social support and subjective well-being of nurses.This results supports evidence for nursing managers to cultivation and management of nurses,which is helpful to establish effective nursing manage-ment measures.

OBJECTIVE:To analyze the effects of different disinfectants on results of antibiotics skin test,and to improve the accuracy of the judgment results of antibiotics skin test. METHODS:1 500 patients undergoing antibiotics skin test of penicillin and cephalosporin were randomly divided into group A and group B with 750 patients in each group. Group A was given 75% etha-nol disinfection,and group B was given iodine disinfection. The incidence of false positive results were compared after disinfected with 2 kinds of disinfectants. RESULTS:The incidence of false positive result in group B was lower than in group A,with statisti-cally significant difference (χ2=10.004,P<0.05). CONCLUSIONS:For skin disinfection of antibiotics skin test,iodine is better and safer than 75%ethanol.

Objective To compare the clinical efficacy of ilaprazole standard triple therapy with omeprazole standard triple therapy in the treatment of patients with Helicobacter pylori ( Hp ) positive duodenal bulb ulcer. Methods 100 patients with Hp positive duodenal bulb ulcer were randomly divided into the two groups by lottery, given ilaprazole standard triple therapy and omeprazole standard triple therapy respectively.After 5 weeks of the course,take gastroscopy and the enzyme 13C-urea breath test,and the Hp eradication rate,clinical efficacy,ulcer heal-ing rate and adverse reactions were observed.Results The Hp eradication rate is better than the omeprazole group (92%vs 78%,χ2 =3.853,P<0.05),while the ulcer healing rate were no significant (96%vs 90%,χ2 =1.561, P>0.05).Conclusion It is a good method in the treatment of Hp positive duodenal bulb ulcer for ilaprazole stand-ard triple therapy.

Objective To establish an expression system of TCRγ9/δ2-Fc protein by baculovirus vector ex-pression system and identify biological function of expressed TCRγ9/δ2-Fc protein. Methods γ9Fc and 82 (OT3) Fc gene fragments were amplified by overlap PCR and inserted into expression vector pBACp10ph. The recombinant plasmid pBACp10ph-γ9/δ2(OT3)-Fc and the baculovirus DNA were co-transfected into st9 cells. The expression position of TCRγ9/δ2 (OT3)-Fc was identified by Western blot and the expression efficiency of γ9Fc and δ2 (OT3) Fc was tested by flow cytometry (FCM). Furthermore, the binding activity of TCRγ9/δ2 (OT3)-Fc protein with SKOV3 ceils and MNS protein was evaluated with laser scanning confocal microslopy and surface plasmon resonance (SPR). Results The recombinant vector pBACp10ph-γ9/δ2(OT3)-Fc was constructed and TCRγ9/δ2(OT3)-Fc protein was expressed in sf9 ceils. However, the expression efficiency of γ9Fc and 82 (0T3) Fc was quite differ-ent. It was proved that purified TCRγ9/δ2 (OT3)-Fc protein can bind with SKOV3 cell and MNS protein. Conclu-sion TCRγ9/δ2-Fc protein is successfully expressed in baculovirus vector expression system and TCRγ9/δ2-Fc protein can simulate the binding activity of TCR in vitro.

ObjectiveTo investigate the expressions of folate receptor alpha (FOLR1) in 40 esophageal cancerous tissues and its relevance of ABO blood group.MethodsABO blood groups were analyzed in 40 patients.Immunohistochemistry (IHC) and real-time quantitative reverse transcription PCR detection were used to detect the expression of folate receptor in cancer and adjacent tissues.Results20％of esophageal cancer was suspected positive (+), 50％ of cancer adjacent tissue was suspected positive (+), 10％ were positive (+), the difference was statistically significant (x2 = 14.48, P ＜0.01).Real Time RT-PCR analysis showed FOLRI low expression in esophageal cancer and adjacent tissues, compared to normal esophageal mucosa, the differences were statistically significant (F1 =53.247, F2 = 116.500, P ＜0.01).ABO blood type and FOLRi in esophageal cancer patients were not significant correlated (P =0.647, P ＞0.05).ConclusionsFOLRI expression was decreased in the esophageal lesions compared with adjacent tissues.Detection of FOLRl expression level in esophageal cancerous tissues and the paired adjacent tissues was helpful for judging the extent of disease and guiding surgery treatment.The FOLRI expression level in esophageal carcinoma tissues had no relationship with ABO blood types.

AIM: To assess the changes of macular thickness of acquire immunodeficiency syndrome ( AIDS) patients.
METHODS:The study based on the data analysis of 38 human immunodeficiency virus ( HIV ) positive patients ( 64 eyes ) . According to CD4 count and whether cytomegalovirus retinitis ( CMVR) happened, the patients were divided into 3 groups. Group A included 16 patients (32 eyes), in which CD4 count was < 50cells/μL and CMVR did not happen. Group B included 10 patients ( 20 eyes), in which CD4 count was>50cells/μL and CMVR did not happen. Group C included 12 patients (12 eyes), in which CD4 count was < 50cells/μL and CMVR just happened. Group D included 10 healthy people ( 20 eyes ) , as normal control group. By using optical coherence tomography ( OCT ) , thickness of retina along with a 1mm diameter circle centered on macular was evaluated.
RESULTS:The mean foveal thicknesses in groups A, B, C and D were 254. 03±15. 63μm, 263. 11±17. 12μm, 304. 50±50. 62μm and 257. 64±8. 54μm in order. Compared with foveal thickness in each group, there were significant differences in general (F=12. 933, P=0. 000). The mean foveal thickness in groups CMVR increased, which was of significant difference (P= 0. 000), compared with other groups.
CONCLUSION: CMVR can impair the structure and function of macular, which then seriously affects the visual function of patients. It's helpful to understand the progress and prognosis of CMVR disease by observing macular structure with OCT in early time.
