Objective To study the hemorheology,platelet-activating and hemostasis of severe asphyxiated newborns. Methods Erythrocyte filtration index(IF) ,granule membrane glycoprotein (GMP-140),D-dimer(DD) and yon Willebrand factor(vWF) were measured in 60 severe asphyxiated term newborns and 20 healthy term newborns. The effect of platelet-activating-factor (PAF) antagonist-EGb761 were also obserred. 60 term newborns with severe asphyxia were divided into two groups :treatment group(n= 30) and control group(n = 30). Results During the first day of life the IF,GMP-140,vWF and DD of the severe asphyxiated newborns increased significantly compared with those of healthy newborns(P0.05). Conclusion 1. Severe asphyx iated newborns vary in hemorheology,platelet-activating and hemostasis,which leads to disturbance of microcirculation and organ injury. 2. PAF plays a role in the pathophysiologic process, and PAF antagonist can improve the microcirculation of severe asphyxiated newborns.

Objective To compare the clinical effects and safety of treating newly diagnosed type 2 diabetes patients by combining Glargine insulin with Metformin or/and Acarbose. Methods 84 patients with newly diagnosed type 2 diabetes ,who have a history of weight loss, body mass index( BMI )23 ～ 28kg/m2 and poorly controlled blood glucose in Metformin at least a month ,were randomly divided into three groups. Glargine insulin plus Mefformin were used in group A. Glargine insulin plus Acarbose(without mefformin)were used in group B, Glargine insulin, Acarbos and metformin were used in Group C. All three groups were given a 12-week follow-up. Results FBG,2hBG and HbA1c levels were lower in the patients after treatment( P ＜0. 05 ). HbA1c of patients was partly up to the standard in group A and group B,but HbA1c of patients was all up to the standard in group C. The effects in group C were better than those in group A and group B. It had the shortest time to achieve the target and the smallest dose of insulin in group C. BMI in group A and B did not change but decreased in group C(P＞0.05).The incidence of low blood sugar in all three groups was low and no significant difference observed among three groups (P＞0.05). And in all three groups no severe hypoglycemia occurred. Conclusion The method of combining Glargine insulin with Mefformin or/and Acarbose could effectively control blood sugar had little impact on body weight of the newly diagnosed type 2 diabetes patients, and moreover, the incidence of low blood sugar in the newly diagnosed type 2 diabetes patients was lower. It would be the ideal method to treat newly diagnosed type 2 diabetes patients considering the general safety and effectiveness and convenience.

Objective To evaluate the effect of schistosomiasis control in Yunnan Province since achieving the transmission control standards,so as to provide the evidence for formulating the next prevention and control strategy. Methods The schistoso-miasis epidemic monitoring reports,annual reports,relevant information about Oncomelania hupensis snails,and schistosomiasis patient conditions were collected and analyzed for epidemic condition and characteristics of schistosomiasis in Yunnan Province from 2009 to 2012. Results The various epidemic monitoring indicators all decreased. In 2012,compared with 2009,the preva-lence reduced by 33.33%after correction;the number of villages with schistosomiasis patients reduced by 55.56%;the adjusted positive rate of livestock stool tests reduced by 45.45%;the number of villages with infected cow reduced by 42.25%;the actual area with snails reduced by 13.58%;the density of living snails reduced by 25.66%,and no schistosome infected snails were found in 2012. Conclusion There still exist schistosome infections in human and animals in some local areas of Yunnan Prov-ince,and it is difficult to achieve the standard of schistosomiasis transmission interrupted in a short period.

Objective To evaluate the clinical application of enteral nutrition by nasojejunal tube insertion and by percutaneous endoscopic gastrostomy (PEG) in elderly patients.Methods A total of 65 elderly patients with dysphagia recruited at our department from January 2010 to November 2014 were divided into the nasojejunal tube feeding group (35 cases) and the PEG feeding group (30 cases).Differences between these two groups in nutritional indexes,immunological indexes,complications and mortality were analyzed retrospectively.Results Serum total protein,albumin and prealbumin and upper arm circumferences all increased after treatment with nasojejunal tube feeding or percutaneous endoscopic gastrostomy (P＞0.05).There was overall improvement in nutritional status,as assessed by Nutritional Risk Screening 2002 (NRS2002).Specifically,the before/one month-after-treatment ratio of scores was 3.72±0.91/1.90±0.61 (t=7.24,P＜0.01) for the nasojejunal tube feeding group and 3.52±1.23/2.02±0.53 (t=4.17,P＜0.01) for the PEG feeding group.Compared with NRS2002 scores at one month post-operation,further improvement was achieved at 3 months postoperation both for the nasojejunal tube feeding group (1.89±0.65,t=5.21,P＜0.01) and for the PEG feeding group (1.91±0.62,t=4.40,P＜0.01).There was no difference in the indexes of nutrition,immune status or mortality between the two groups (P＞0.05).Although improvement in CD3+,CD4+,CD8+,CD4+/CD8+,IgA,IgG,and IgM was seen in both groups after operation,the differences did not reach statistical significance (P＞0.05).The incidence of aspiration pneumonia was notably lower (P＜0.05) while the incidence of diarrhea was much higher (P＜0.05) in the nasojejunal tube feeding group than in the PEG feeding group at one month and three months.The two groups had similar causes of death and mortality rates.Conclusion Both nasojejunal tube and PEG feeding can improve the nutritional status of elderly patients with dysphagia.However,the choice for the route of nutrition should be individualized.

0.05)and the TNM staging (P=0.55).A mild elevated compared other pathological classification was found in small cell lung cancer (0.191?0.275).Conclusions The results showed that RFQ-PCR was suitable for measurement of the mRNA level of PLKI in bronchoscopic bioptic specimens.This study suggest elevated expression of PLK1 might play a important role in development of lung cancer,so that PLK1 might be a potential tumor marker for Lung cancers.Advanced studies will be needed to clarify that PLKI mRNA level do not relate to TNM staging and pathological classification.

Objective To explore the sleep characteristics of adult partial epilepsy patients. Methods 45 patients newly diagnosed as adult partial epilepsy and 40 cases of healthy controls were monitored with sleep encephalogram (EEG), the sleep parameters were analyzed.Epworth Sleepiness Scale (ESS) was used to evaluate the daytime sleepiness next day. The sleep parameters and ESS score were compared between 2 groups, and the correlation between sleep parameters and ESS score in the patients were analyzed. Results The ESS score was higher in the patients than in the controls (P<0.05); Compared with the controls, the total sleep time decreased (P<0.05), the sleep efficiency reduced (P<0.05), the percentage of non-rapid eye movement sleep (NREM) stages 1 and 2 and the wakefulness stage increased (P<0.05), the percentage of NREM stages 3 and 4 decreased (P<0.05) in the patients; There was no significant difference in total recording time, sleep latency, REM latency, and arousal times between the patients and the controls (P>0.05). The ESS score was higher in the patients who attacked 3 times a month or more (group A) than less than 3 (group B). Compared with group B, the total sleep time decreased (P<0.05), the sleep efficiency reduced (P<0.05), the percentage of NREM stages 1 and 2 and the wakefulness stage increased (P<0.05), the percentage of NREM stages 3 and 4, and REM decreased (P<0.05) in group A. There was no significant difference in sleep latency, REM latency and arousal times between 2 groups (P>0.05). The ESS score of the patients was negatively correlated with sleep efficiency (r=-0.49, P<0.05) and the percentage of NREM stages 3 and 4 (r=-0.54, P<0.05), and was not correlated with other sleep parameters (P>0.05). Conclusion The sleep architecture of patients with adult partial epilepsy is abnormal, and their daytime sleepiness is more than healthy persons. Epileptic seizure can aggravate sleep architecture abnormality and daytime sleepiness. Abnormal sleep parameters are related with ESS score.

The purity of 4,4′-dimethoxy-5,6,5′,6′-bis (methylenedioxy)-2′-morpholine methylenebiphenyl-2-methyl formate methanesulfonate (IMH), a new drug for fatty liver treatment, was determined through differential scanning calorimetry (DSC). Analysis of two-factor non repeatability method was performed in the investigation the effects of two factors (heating rate and sample weight) on purity determination. The DSC experimental parameters were optimized as follows: heating rate was 10 ℃·min^-1, temperature range was 150-300 ℃, sample weight was 2.0-4.1 mg, and N₂ flow rate was 80 mL·min^-1. The linear correlation coefficient (r) of this DSC method was 0.999 8. The RSD value (n = 6) of precision was 0.03%. The standard value and uncertainty of the purity results of the multiple batches of IMH drugs were (99.74 ± 0.29)%, (99.91 ± 0.28)%, (99.90 ± 0.28)%, and (99.81 ± 0.28)% with inclusion factor (K) of 2 and confidence probability (P) of 0.95. The results were basically consistent with the results of the mass balance method. The DSC mehod is a simple, rapid and accurate method, and provides a new reference method for determining the purity of IMH drugs, improves the accuracy and reliability of purity determination.
