As a vital component in an overall laboratory animal care and use program , development of a disaster plan plays a critical role for every research institution .Currently, most of domestic institutions would draw up an“emergency operation plan , EOP”, but ignoring a practicable “business continuity plan , BCP” in establishing a disaster plan.In this article, we will discusse about the definition of disaster , how to set up an EOP, and how to establish a thorough BCP , in order to show an integrated and professional disaster plan in laboratory animal care and use program .

Objective To compare the safety and effectiveness of three types of intrauterine device (IUD) inserted immediately after artificial abortion.Methods A randomized controlled clinical trial was performed in 4 family planning service stations in Pudong New Area from January to December 2012.Total 1 200 eligible women were randomly assigned to receive three types of IUD:MYCu,TCu380A or G-Cu200 (n =400 in each group) immediately after vacuum aspiration.All subjects were followed up for 12 months.The cumulative rates of termination of three IUD after 12 months were analyzed with WHO LTA 2.0 life table.Results Total 1 199 subjects were followed up for 12 months with a drop-out rate of 0.08％ (1/1 200).No any uterine perforation was found.During the 12 months the pregnancy rates with IUD in situ in MYCu,TCu380A and G-Cu200 groups were 0.26/100 women year,0 and 0.52/100 women year,respectively (x2 =1.951,P ≥ 0.2).The rates of expulsion in three groups were 0.26/100 women year,1.84/100 women year and 2.05/100 women year,respectively(x2 =5.539,P =0.066).The remove rates related to bleeding and paining in three groups were 1.26/100 women year,7.29/100 women year and 2.76/100 women year,respectively (x2 =21.625,P =0.001).The discontinuation rates related to IUD use in there groups were 3.25/100 women year,9.00/100 women year and 5.50/100 women year,respectively(x2 =12.191,P =0.004).The rates of Abnormal position in three groups were 1.51/100 women year,0 and 0.26/100 women year,respectively (x2 =8.649,P =0.014).Conclusion Three IUDs inserted immediately after vacuum aspiration are all effective.Among three IUDs,MYCu shows lower expulsion rate,lower discontinuation rate related to IUD use and higher continuous rate; but the abnormal position rate of MYCu is higher than other two types IUD.

The types of the voltage-dependent calcium channels (VDCCs) in human ejaculatory sperm and the effects of calcium channel blocker (CCB) on human sperm motility parameters in vitro were investigated. The human sperm motility parameters in vitro in response to the pharmacological agents nifedipine (NIF, inhibitor of L-type VDCC) and co-conotoxin (GVIA, inhibitor of N-type VDCC) were compared and analyzed statistically. The results showed that NIF (1, 5, 10 micromol/L) could not only significantly affect human sperm's shape but also spermatozoa motility after incubated at least 10 min in vitro (P<0.001). GVIA (0.1, 0.5 and 1 micromol/L) could just only significantly affect human sperm's progressive motility (a %+b %) after incubated for 20 min in vitro (P<0.01), but they both could not significantly affect spermic abnormality rate. It is suggested that L-type VDCC, non L-type VDCCs and isoform of L-type VDCC exist in the cell membrane of human sperm solely or together, and they participate in the spermic physiological processes especially the spermic motility.

Objective To review the experience in the management of gastric cancer with liver cirrhosis and portal hypertension.Method A retrospective analysis was made in 35 gastric cancer cases with liver cirrhosis and portal hypertension admitted into our hospital from January 2000 through June 2009.Result There were no intraoperative death in this group.Postoperative ascites occurred in 19 patients,anastomotic leakage in one case,anastomotic bleeding in 2 cases,wound bleeding in 2 cases,intraabdominal infection in 17 cases (of which combined fungal infection in 4 patients),incision infection in one patient and chylous leakage in one case.The morbidity rate was 71%.Four patients died during hospitalization including multiple organ dysfunction syndrome in 2 cases,with mortality rate of 11%. Conclusion In order to reduce the incidence of mortality and complications,we should complete preoperative evaluation,correct perioperative management,guide surgery with damage control concept,follow individualized principles and emphasize on preventive devascularization.

Objective To investigate the clinical application value of ultrasonic rapid paraffin section in intraoperative diagnosis of breast tumor.Methods Twenty-five patients of breast tumor specimens were admitted from December 2012 to December 2013,including 19 cases from surgery,4 cases from gynecology,2 cases from medical patients.Twenty-five cases were used with ultrasonic rapid paraffin section and the remaining tissues were used as conventional paraffin section,then compared the two methods.Results This study took two different ways but the same results were achieved with 23 cases,the diagnostic accuracy was 92.0％ (23/25).Two of 25 cases were misdiagnosed with the misdiagnosis rate was 8.0％ (2/25).One patient appeared delayed diagnosis,accounting for 4.0％(1/25).After 25 cases of breast cancer biopsy treated with ultrasonic rapid paraffin section,benign lesions was 20 patients,with the highest incidence of breast adenosis of 9 cases (36.0％,9/25).The malignant lesions was 4 patients with invasive ductal carcinoma in which the highest incidence,accounting for 3 cases (12.0％,3/25).Delay diagnosed 1 case of intraductal papilloma.Conclusion Ultrasonic rapid parafifin section is widely used in clinical application,with high quality and diagnostic biopsy rate and other characteristics,so it is worthy of clinical application.

Objective To investigate the effect of comprehensive nursing intervention on the quality of life of patients suffering from hypertension. Methods A total of 120 cases of essential hypertension were evenly randomized into observation group and control group. Both groups received conventional antihypertensive drug and nursing, and additionally, the observation group was given intervention of comprehensive nursing including dietary regulation, exercise training, emotional care and medication instruction. The intervention lasted 3 months. Before and after the intervention, traditional Chinese medicine ( TCM) symptom classifying list and World Health Organization ( WHO) QOL-BRIEF were applied to evaluate the therapeutic effect of the two groups. The changes of blood pressure, clinical manifestation and the quality of life were also compared between the two groups. Results (1) After intervention, the systolic pressure and diastolic pressure were both improved in the two groups ( P<0.05 or P<0.01 compared with those before treatment) , and the improvement in the observation group was superior to that in the control group (P<0.01). (2) After intervention, the scores of TCM symptom scores and QOL-BRIEF total scores were improved in the two groups ( P<0.05 or P<0.01 compared with those before treatment) , and the improvement in the observation group was superior to that in the control group ( P<0.01). Conclusion TCM comprehensive nursing intervention can effectively relieve hypertension and improve the quality of life of hypertension patients.

Objective: To explore the relationship between the ratio of neutrophil/lymphocyte (NLR) and in-hospital major adverse cardiac events (MACE) in patients with acute ST-elevation myocardial infarction (STEMI) at early admission.
Methods: A total of 420 acute STEMI patients admitted and received primary PCI in our hospital from 2010-01 to 2014-12 were retrospectively studied. The patients were divided into 2 groups:In-hospital MACE group, n=47 and Normal discharged group, n=373. Uni-and multivariate analyses were conducted to assess whether high NLR is the independent predictor for in-hospital MACE occurrence.
Results: Univariate regression analysis indicated that the occurrence rate of in-hospital MACE in high NLR patients were higher than those in low NLR patients (OR=3.19, 95%CI 1.55-2.65, P=0.012). Multivariate regression analysis showed that high NLR was the independent risk factor for in-hospital MACE occurrence in STEMI patients (OR=3.05, 95%CI 1.59-10.54, P=0.015).
Conclusion: High NLR is the independent risk factor for in-hospital MACE occurrence in STEMI patients at the early admission.
