Objective To discuss the management and maintenance of clean operation room. Methods The equipment and operation section in operation room were managed and maintained to meet the requirement of clean operation room. Results Under the management, all indexes reached the standard. Conclusion Only if the importance be attached to the management and maintenance of clean operation room, and the rules be strictly observed, does the clean operation room be well maintained, the hospital infection caused by operating room be effectively controlled and the quality of medical treatment be improved.

Objective To investigate the protective effect of gynostemma on myocardium and its mechanism in patients with diabetes associated with hyperlipemia.Methods 178 patients with type 2 diabetes mellitus with hyperlipidemia from the department of endocrinology in our hospital were selected and divided into two groups, 89 cases in the control group treated with basic treatment of diabetes+atorvastatin, 89 cases in the experiment group received gynostemma on the basis of the control group, myocardial injury index, blood glucose level, blood lipid level, serum cytokine levels and serum oxidative stress response indexes were detected and compared after the treatment.Results Compared with the control group, serum levels of aspartate aminotransferase(AST), creatine kinase(CK), CK-MB, lactate dehydrogenase(LDH)were lower in the experiment group after treatment, fasting plasma glucose(FPG), 2h postprandial blood glucose(2hPG), HbA1c level were lower after treatment, serum levels of total cholesterol(TC), triglycerides( TG ) , low-density lipoprotein cholesterol ( LDL-C ) were lower, high-density lipoprotein cholesterol ( HDL-C ) level was higher after treatment, serum level of adiponectin(ADPN) was higher, tumor necrosis factor-alpha(TNF-α), interleukin-6(IL-6), interleukin-18(IL-18) levels were lower after treatment, serum levels of malondialdehyde(MDA), reactive oxygen species(ROS) were lower, glutathione peroxidase(GSH-Px), superoxide dismutase(SOD) levels were higher after treatment, with significant difference (P<0.05).Conclusion Gynostemma can significantly reduce the cardiac muscle damage of patients with diabetes associated with hyperlipemia , plays a role in myocardial protection, the mechanism may be to reduce blood glucose and blood lipid levels, inhibit the inflammatory reaction caused by inflammatory cytokines, improve the antioxidant capacity of the body and reduce oxidative stress damage.

In order to investigate the relationship between the expression of heme oxygenase-2 (HO-2) mRNA and the pathogenesis of Hirschsprung's disease (HD), total ribonucleic acid (RNA) was extracted in the aganglionic and ganglionic segments of colon respectively from 15 cases of HD. The single-stranded cDNA of HO-2 was synthesized and further amplified by reverse transcription-polymerase chain reaction (RT-PCR). The expression of HO-2 mRNA was normal in ganglionic segments, but absent in aganglionic segments. It is concluded that the absence of HO-2 mRNA expression may be an important mechanism responsible for HD.

Objective To evaluate the value of high frequency color Doppler ultrasound in diagnosis of malignant tumor in the parotid gland.Methods High frequency ultrasound was used to observe shape and internal echo texture of tumor,color Doppler flow imaging(CDFI) was added to observe blood flow signal,peak systolic velocity(PSV) and resistance index(RI) were measured by pulsed wave Doppler, and lymphonodus around parotid gland were examined.Results The features of ultrasonography included round,lobulated and irregular shape.Three types of boundary were clear but not smooth,unclear,irregular and invasive.Internal echo texture included low and irregualr echo,cystic echo,spot like and intensive echo,honey comb like echo.CDFI showed spet like,stick like blood flow signal.PSV and RI were 4.6 17.5 cm/s,and 0.69 1.14 .Eight cases were misdiagnosed for benign tumor,the correspondent rate was 87.1% .Conclusions The high frequency ultrasonogram of malignant tumor in the parotid gland were similar and specific,adding the CDFI,PSV,RI and lymphonodus examination around the parotid gland may help to improve the diagnostic accuracy.

Visual perceptual learning refers to the special improvement of perceptual performance benefit from repetitive training with a visual task.A typical time course of visual perceptual learning presents an initial rapid improvement,and then gradually processes like an asymptote in gain.During the process of perceptual learning,the influence of critical amount and perceptual learning rules on learning effect,memory consolidation and interference,and the role of sleep on preventing interference and promoting consolidation in perceptual learning,all get involved.This article reviewed the aforesaid content and then elaborated some strategies in application of visual perceptual learning in the treatment of amblyopia.

Objective To explore the efficacy and safety of terminating biochemical pregnancy (the stage in which intrauterine or ectopic pregnancy cannot be confirmed) with mifepristone and misoprostol. Methods Mifepristone (150 mg) combined with misoprostol (600 ?g) 3 days later were given to 500 biochemical pregnancies (G_1),500 early clinical pregnancies (G_2) and 500 clinical pregnancies (G_3) which were classified according to amenorrhea days,serum human chorionic gonadotropin-beta subunit (?- hCG) and vaginal B-ultrasonic examinations.All were observed for 6 hours after taking misoprostol and returned for assessment per week.Results Expulsion of conceptus was G_1 123 (24.6%,123/500),G_2 438 (87.6%,438/500) and G_3 467 (93.4%,467/500).Failure rate was G_1 6 (1.2%,6/500),G_2 24 (4.8%,24/500) and G_3 79 (15.8%,79/500) for ongoing pregnancies,hospitalizations for suspected ectopic pregnancies and surgical intervention for heavy or long-time bleeding.Bleeding cases during the administration of mifepristone were G_1 272 (54.4%,272/500),G_2 141 (28.2%,141/500) and G_3 87 (17.4%,87/500);the mean bleeding days were G_1 (5.8?1.5),G_2 (9.0?2.9) and G_3 (14.3?5.9) days.Other side effects including abdominal pain,nausea,vomiting and diarrhea were low and light in each group,increasing with advancing gestational age.Menses recovery was 486 (97.2%,486/500),452 (90.4%,452/500) and 433 (86.6%,433/500) for each group on scheduled time.Satisfaction was 499 (99.8%,499/500),485 (97.0%,485/500) and 369 (73.8%,369/500) respectively.Conclusion Mifepristone and misoprostol in combination is as safe,and effective for termination of biochemical pregnancies as ordinary medical abortion.It does not need to wait till ectopie pregnancy is excluded.
