Objective To investigate the protective effects of Green Tangerine induced hypertension and mild hypothermia on focal cerebral ischemia and reperfusion and local cerebral glucose utilization(LCGU)in the in- farction rim in rats.Methods A total of 64 rats were used and randomly divided into a control group,a Green Tan- gerine induced hypertension group,a mild hypothermia group and a combination therapy group.The neurologic defi- cits,infarct size and LCGU were observed in the rats with focal cerebral ischemia and reperfusion.Results Com- pared with the control group,the neurologic deficits(P

Objective To explore the analgesic effect of ropivacaine combined with sufentanil in epidural anesthesia on walk on painless labor.Methods 134 cases of maternal pregnancy were selected and randomly divided into two groups.61 cases were treated with conventional delivery,73 cases in the experiment group were treated with walk on painless labor.The visual analogue scale and improved Bromage classification score were compared at the first stage of labor,the second stage of labor,the third stage of labor.Results Compared with the control group,the rate of cesarean section was higher(P<0.05),The visual analogue scale was higher at the first stage of labor,the second stage of labor,the third stage of labor,the duration of labor were lower at the first stage of labor,the second stage of labor,the third stage of labor(P<0.05),and there was no significant difference between the two groups in the motor nerve block.Conclusion Ambulatory labor analgesia on maternal effect significantly,can significantly reduce the pain degree of maternal birth process and deliverry time,postpartum less complications.

Objective To analyze the correlation of hypersensitive C-reactive protein(hs-CRP),homocysteine(Hcy) and D-dimer(D-D) with pathological change degree of coronary heart disease(CHD),and to investigate the diagnostic specificity and sensitivity of joint detection in CHD.Methods A total of 100 cases of CHD patients(experimental group) and 100 healthy subjects(control group) were enrolled,.Patients of the experimental group were divided into four groups on the basis of complications,including simple CHD group(32 cases),amalgamating hypertension group(46 cases),amalgamating diabetes group(9 cases),amalgamating hypertension diabetes group(13cases).The levels of hs-CRP,Hcy and D-D in the five groups were detected and analyzed.Results The levels of hs-CRP,Hcy and D-D in the experimental group were all higher than the control group(P<0.05).Logistic regression confirmed that three indexes were the independent risk factors for CHD.Each indicator has a certain clinical significance to the diagnosis and treatment of CHD but the value of Hcy could be better.Joint detection of hs-CRP and Hcy could be an ideal combination of detection,and the three joint detection might not be suitable for early diagnosis and treatment of CHD.The levels of hs-CRP and D-D in simple CHD group,amalgamating hypertension group,amalgamating hypertension diabetes group were all higher than amalgamating diabetes group(P<0.05).Conclusion hs-CRP,Hcy and D-D could be the independent risk factors of CHD,and joint detection might be with important clinical value for diagnosis of CHD.

Objective To study the clinical outcome of endoscopic vessel harvesting system (EVH) for the treatment of lower limbs varicose veins.Methods Patients (n =41) with varicose veins admitted from Jan 2011 to May 2013 were randomly divided into EVH group (n =20) and stripping group (n =21).Indexes as postoperative VAPS (48 hours and 1 week),subcutaneous ecchymosis (1 week),hematoma(1 week),skin numbness (1 week),CEAP classification (3 months),surgery effect and satisfaction scores(3 months) were compared between the two groups.Results 48 hours and 1 week VAPS was lower in EVH group(P ＜0.01).After EVH there was less subcutaneous ecchymosis (1 week),hematoma(1 week) and skin numbness (1 week) (all P ＜ 0.01).Postoperative CEAP classification improved significantly in both groups (P ＜ 0.01),while surgery effect and satisfaction scores (3 months) were better in EVH group (P ＜ 0.05).Conclusions EVH is a safe and minimally invasive technique in treatment of varicose veins of the lower limbs.

NGOs play an important role in global health governance, and have become the key partners of World Health Organization ( WHO) , European and American governments. The goal of the sustainable development of the United Nations also proposes to strengthen NGOs as global health governance partners. Taking WHO, the Unit-ed States and Britain as case examples, this study reviewed the NGOs positioning and cooperation in their global health strategies. The results found that these entities explicitly define the roles of NGOs and strengthen cooperation in their global health strategies to expand their influence in the field of global health. Results also found that WHO, US and UK have given NGOs a clear positioning, that is, they have strengthened the mutual cooperation ( partner-ships) in the same way of expanding their influence in the field of global health for China’s global health strategy de-velopment referred to those NGOs. Therefore, China should incorporate NGOs into the global health strategy, estab-lish NGOs management and cooperation mechanism and define their roles and make it an important complement to global health. China should also strictly select international NGOs to cooperate with and strive to nurture and support Chinese NGOs to participate in global health programs set by the Government, formulate the cooperation list and neg-ative list for NGOs, and at the same time strengthen the supervision and audit to avoid possible risks of NGOs.

OBJECTIVETo evaluate the clinical outcome of surgical venous thrombectomy and simultaneous stenting in patients with acute, symptomatic iliofemoral deep venous thrombosis (DVT).

METHODSFrom October 2008 to December 2010, a total of 15 patients with acute symptomatic DVT underwent combined surgical venous thrombectomy and endovascular stenting in ipsilateral iliac vein. There were 6 male and 9 female patients, with a mean age of 57.4 years (ranging from 36 to 71 years). All patients underwent Duplex ultrasonography for diagnosis of DVT. The location of thrombosis was femoro-ilio-caval vein in 2 cases, bilateral iliac vein in 1 case and left iliofemoral vein in 12 cases. All patients had leg swelling and 12 cases had severe leg pain. The mean time of symptomatic DVT occurring at operation was 3.3 d. The factors related to DVT were operation in 6 cases, DVT reoccur in 2 cases. Coexist diseases were digestive tract bleeding in 1 case, gastric ulcer in 1 case, hypertension in 3 cases and 1 case had cerebral infarction. The inferior vena cava filter was inserted before thrombectomy, iliac vein compression and residual stenosis were treated with a self-expandable stent after thrombectomy.

RESULTSIntraoperative venography showed severe venous stenosis in all patients including 80% of iliac vein compression syndrome, 18 self-expandable stents were inserted successfully, the procedural successful rate was 100%, the 30-day mortality rate was 0.One case was suffered from hematoma at incision after operation. 3 patients were lost during follow-up. Median follow-up was 10.3 months (ranging from 2 to 26 months). There was no case of re-thrombosis. Leg pain was disappeared in all cases and only 2 patients showed slight leg swelling after excise.

CONCLUSIONCombined surgical thrombectomy and endovascular treatment for patients with acute symptomatic iliofemoral venous thrombosis is an effective and safe technique with low morbidity and good clinical results.

OBJECTIVETraditional detection approaches for non-O157 STEC are both time and labour consuming in diseases surveillance. Virulence genes detection based on multiplex PCR could not only improve the detection efficiency but also increase the accuracy.

METHODSSix virulence genes of non-O157:H7 (stx1, stx2, eae, hly, etpD, katP6) were detected by two groups of trebling PCRs. The multiplex PCRs were optimized by melting curve analysis in SYBR Green I real-time PCR. Testing result of multiplex PCR was consistent with serological testing.

RESULTSThe sensitivity limits of the multiplex PCR for stx1, stx2, eaeP, etpD, katP, and hly were 10 ng/ml, 120 ng/ml, 110 ng/ml,165 ng/ml, 85 ng/ml, and 15 ng/ml, respectively, which is similar with that of single PCR. When the multiplex PCR was applied in 120 adults and 90 children diarrhea samples detection, 13 cases were detected for non-O157 positive.

CONCLUSIONThe method we established can be used for non-O157 STEC virulence genes detection and screening with high efficiency and accuracy.

OBJECTIVETo analyze the polymorphism of natural killer cell immunoglobulin-like receptor (KIR)gene and the characteristics of its genotypes and haplotypes in Korean ethnic group of Jilin area, and to compare with that of Han nationality.

METHODSDNA samples randomly collected from 214 Han and 160 Korean populations were genotyped with PCR-SSP method, and KIR genotypes and haplotypes were assigned according to the standard model by Hsu et al.

RESULTSAll individuals contain KIR 3DL3, KIR 2DL4, KIR 3DL2 with the genotype frequency of 100%; the most common genotypes were 2DL1, 2DL3, 3DL1, 3DP1(*)003 and 2DP1; the genotypes with low frequency were 2DL2, 2DS2, 2DS3, 3DP1(*)001/002/004. Thirty-nine different KIR genotype and 16 haplotypes had been found in Korean and Han individuals. The most common KIR genotypes were AJ and AF with frequency of 18.1%, 19.4% and 31.8%, 19.6%, respectively. The most common KIR haplotype was haplotype 2 with frequency of 41.8% (n = 127) and 51.2% (n = 216) (P < 0.05), respectively.

CONCLUSIONKIR gene distribution in Jilin Korean ethnic group showed some common features of KIR gene polymorphisms in Chinese Han population, but also showed this nation's unique characteristics of KIR gene polymorphism.

Objective: To investigate the current status of prevention and control of occupational hazards in a city in 2017, to understand the capability to prevent and control occupational hazards and the level of occupational health supervision and management, and to propose measures to urge employers to assume the main responsibility for the prevention and control of occupational diseases. Methods: An analysis of the main factors influencing the prevention and control of occupational hazards in the city was performed to screen out six semi-quantitative assessment indicators (including the training of the main responsible persons and occupational health management personnel in companies) and four qualitative assessment indicators (including the coverage of supervision and inspection of occupational hazards performed by the district safety supervision department) , which could be used to measure the prevention and control effects of regional occupational hazards. Each indicator was scored. The typical investigation method was used to do data review and on-site inspection of 170 companies, 17 district-level occupational health supervision departments, and 16 sub-district (township) occupational health supervision departments in the city from October to December, 2017. The prevention and control of occupational diseases in each district was scored, and the completion rate and completion situation of each indicator in the city were analyzed. Results: The mean score of prevention and control of occupational hazards in the city was 84.9. The scores of two districts were relatively high, being 88.9 and 88.7, respectively; the scores of 9 (52.9%) districts were higher than 85. The pass rate of training for the main responsible persons and occupational health management personnel in companies in the city was 95.9%, the pass rate of occupational health training for workers was 84.7%, the pass rate of occupational health examination for workers was 96.5%, the pass rate for the inspection of occupational hazardous factors in workplaces was 95.3%, the pass rate for notifying occupational hazards in workplaces is 95.9%, and the pass rate for applying the warning signs of occupational hazards in workplaces was 76.5%. Conclusion The awareness of the importance of prevention and control of occupational hazards in all districts of the city has been increased, but the effectiveness of occupational health training for workers needs to be strengthened. The supply and demand of occupational health technical services are still not matched, and the ways and methods of occupational health supervision and inspection need to be improved.
