Objective To discuss the nursing care after the treatment of lower limb deep venous thrombosis by using thrombolytic drug from lateral dorsum of foot vein.Methods 32 patients with lower limb deep venous thrombosis were treated by using micropump pumping thrombolytic drug from lateral dorsum of foot vein,and administration of heparin sodium,706 artificial plasma and danshen root,in combination with nursing care,healthy guidance,observing the signs,symptoms and the effect of treatment.Results Of 32 cases,12 cases were complete recovery,19 cases were partial recovery and 1 case was noneffective.Conclusion Correct nursing care is important in the patients with lower limb deep venous thrombosis after thrombolytic treatment.

Objective To develop a method for the determination of 13 kinds of organic phosphorus pesticides in the water by gas chromatography-mass spectrometry with solid phase extraction(SPE).Methods The 13 organic phosphorus pesticide residues,including dichlorvos,mevinphos,phorate,diazinon,propetamphos,ddimethoate,methyl parathion,malathion,fenitrothion,parathion,phenthion,methidathion,ethion,were separated on DB-1701P elastic silica capillary column followed by SPE with carbon-amino group complicated column and analyzed by gas chromatography mass spectrometry.Methylene dichloride was elution solvent,injection inlet temperature was 280 ℃ and column flow rate was 1.2 ml/min.Results The leaner range and limit of detection was 0.05-2.5 mg/L,0.49 ?g/L for dichlorvos;0.10-2.5 mg/L,1.4 ?g/L for mevinphos;0.05-2.5 mg/L,0.96 ?g/L for phorate;0.05-2.5 mg/L,0.73 ?g/L for diazinon;0.05-2.5 mg/L,0.60 ?g/L for propetamphos;0.05-2.5 mg/L,1.8 ?g/L for ddimethoate;0.10-2.5 mg/L,2.2 ?g/L for methyl parathion;0.05-2.5 mg/L,0.34 ?g/L for malathion;0.05-2.5 mg/L,1.1 ?g/L for fenitrothion;0.10-2.5 mg/L,0.58 ?g/L for parathion;0.05-2.5 mg/L,1.2 ?g/L for phenthion;0.05-2.5 mg/L,0.77 ?g/L for methidathion;0.50-2.5 mg/L,0.26 ?g/L for ethion.For all thirteen organic phosphorus pesticides,the correlation coefficient was above 0.99.The average recovery rates were 94.40%-100.80% and RSDs were found in the range of 4.17%-14.73%.Conclusion The method is simple,rapid,sensitive,accurate and applicable to the simultaneous determination of 13 kinds of organic phosphorus pesticide residues in water.

Objective To evaluate the effects of percutaneous balloon mitral valvuloplasty (PBMV) on repeated rheumatism attacks after continual anti rheumatic treatment in vain over a long period of time.Methods 23 cases received treatment by PBMV and follow up visits were performed.Results After operation,patients' cardiac function and their physique were improved obviously and the activity of rheumatism ceased after routine anti rheumatic treatment and prevention of streptococcal infection.Follow up visits for 36～81 months showed that mitral re stenosis occurred to only 2 patients.Conclusion Patients with mitral stenosis whose rheumatism attacks repeatedly in spite of longterm anti rheumatic treatment may be treated with PBMV first and then given anti rheumatism.In this way,a better curative effect can be obtained.

AIM: To establish a standard for quality control of Xinfang Biyan Capsule(Radix Saponikovae, Radix Angelicae Dahuricae, Radix Scutellariae, etc.). METHODS: TLC and HPLC were used. RESULTS: Flos Magnoliae, Radix Saponikovae, Flos Chrysanthemi, Radix Bupleuri in the capsule could be identified by TLC, and baicalin content in the capsule could be measured by RP-HPLC with a linear relatioship at a range of 0.243 ?g- 2.43 ?g(r= 0.999 8 ). The average recovery was 98.15% and RSD was 0.15% . CONCLUSION: The methods are accurate and can be used for the quality control of Xinfang Biyan Capsules.

Objective:To identify the effect of ?-synuclein overexpression on mitochondrial membrane structure with atomic force microscopy. Methods:?-syn expression was mediated by AAV (adeno-associated viral vector) and Recombinant AAV/?-syn and AAV/LacZ viral particles were stereotaxically injected in the left side of rat substantia nigra (SN) for rat model of ?-synuclein overexpression. Mitochondria were isolated from rats SN of Brain. Mitochondria were analysis with JC-1 staining,atomic force microscopy and Western blot. Results:By 16 weeks post-infection of AAV-?-syn,the level of ?-syn increased about 2 times in mitochondrial fraction with Western blot and mitochondrial membrane potential (??) decreased with JC-1 staining. Furthermore,mitochondria swelling and porous like structure formed on the mitochondrial membrane with atomic force microscopy. Conclusion:The data suggested that ?-syn could accumulate in mitochondria,might form mitochondrial membrane pores and lead to ?? decreases. ?-syn might lead to mitochondrial dysfunction in Parkinson's disease.

Objective To observe the clinical effect and safety of umbilical cord blood mesenchymal stem cell(UCB-MSC) transplantation in the treatment of diabetic foot. Methods UCB-MSC suspension (cell concentration (3 -7) × 107/L,0.3 -0.5 ml per point) was injected into multiple spots on affected lower limb with a 3 cm × 3 cm istance among each point. Demixing injection could be performed in regions with multilayer muscles. Clinical symptoms and related index were routinely observed from the first day to three months after operation. Results After three months of UCB-MSC transplantation, pain of patients was relieved, skin temperature increased, intermittent claudication ameliorated, ulcer healed, ankle-brachial index and transcutaneous partial pressure of oxygen increased. The lower extremity lesions showed an abundant collateral vessel formation after the treatment in 2 patients by angiography. Both patients had no severe complications and adverse reactions, none underwent amputation. Conclusions Umbilical cord blood mesenchymal stem cell transplantation is a safe and effective treatment of diabetic lower limb ischemic disease, which can exempt the patient from amputation and improve their quality of life.

Objective To study cost-effectiveness of primary cerebral infarction patients. Methods The neural function of primary cerebral infarction patients was studied by the National Institutes of Health Stroke Scale (NIHSS) with rank test and multiple regression analysis. Results After treatment in hospitals of different grades, no obvious difference was detected in the NIHSS score, but difference was found in therapy cost and therapy time; the NIHSS score and therapy time of primary cerebral infarction patients in different attack positions were obviously different, but therapy cost had no significant statistical difference. The NIHSS score of primary cerebral infarction patients with different treatments was obviously different, but therapy cost and therapy time was not. Conclusions Patients are advised to choose grade hospitals in nearby cities for treatment. Clinician are expected to choose low-cost treatment plan to relieve patients' economic burden.

OBJECTIVE:To provide scientific reference for rational,effective and economical drug use in pediatric depart-ment. METHODS:A total of 9771 prescriptions were randomly selected from children's branch of our hospital during May 2012-Apr. 2016. Those prescriptions were analyzed statistically in respects of drug type,prescription cost,utilization rate of injec-tion,utilization rate of essential medicine,clinical diagnosis,irrational drug use,use of antibiotics,etc. RESULTS:Among 9771 prescriptions,2.91 types of drugs were used in each prescription,and each prescription expended 77.10 yuan;utilization rate of in-jection was 57.11％,and that of national essential medicine was 67.80％. Respiratory tract disease was main disease (84.17％). There were 284 irrational prescriptions(2.91％),including 156 non-standard prescriptions,165 unsuitable prescriptions and 65 ex-traordinary prescriptions. Utilization rate of antibiotics was 18.25％,among which that of Cefoxitin sodium injection was the high-est(15.48％),but its utilization index was the lowest(0.58). The detection rate of microorganism isolated from bronchitis patients was in low level(45.10％). CONCLUSIONS:The rate of qualified prescription in the children's branch of our Hospital is higher than the requirement of the former Ministry of Public Health concerning the rate of qualified prescription >95％;utilization rate of antibiotics and injection are both in high level. In the future,it is necessary to strengthen prescription evaluation and promote stan-dard and rational use of drugs so as to guarantee safe,effective and economical use of drugs in clinic.
