2.Analysis of the relative factors of angiographic no reflow phenomenon after percutaneous coronary intervention of patients with H type hypertension merge acute myocardial infarction
Chinese Journal of Primary Medicine and Pharmacy 2013;20(20):3092-3094
Objective To study the related factors of coronary no-reflow phenomenon in H-hypertensive acute myocardial infarction (AMI) patients after percutaneous coronary intervention (PCI).Methods 120 AMI patients were selected as the study subjects,all patients were given PCI,the infarct-related coronary artery stenosis forward flow(TIMI) grade ≦ 2 level was the no-flow criteria.The patients were divided into two groups:the no-reflow group (35 patients),the other 85 cases classified as normal blood group.The age,gender,body mass index (BMI),history of diabetes,hyperlipidemia hyperlipidemia history,family history,blood glucose,homocysteine (Hcy),white blood cell count,C-reactive protein (CRP),erythrocyte sedimentation rate (ESR),creatine kinase (CK),creatine kinase (CK-MB),triglycerides,total cholesterol,high density lipoprotein (HDL),low density lipoprotein (LDL),troponin-Ⅰ (cTn-Ⅰ),treatment time and other factors were observed and compared.Logistic regression analysis was used to identify relevant factors of no-reflow.Results 120 patients with primary PCI,no-reflow in 35 patients,the incidence rate was 30.1%.The sex,smoking history,history of hyperlipidemia,diabetes,history of angina,and Killip classification before treatment,time from chest pain to before treatment between no-reflow patients and normal blood flow patients had no significant differences (t =1.275,P > 0.05).Multivariate Logistic regression analysis showed that:age,diabetes,triglycerides,HCY,cTn-Ⅰ,CK-MB,CRP were related factors of no-reflow(t =3.427,P < 0.05).Conclusion Age,without pre-infarction history of angina,coronary artery open long hours,admission NYHA low,white blood cell count high,CK-MB and cTn-Ⅰ levels higher are independent risk factors of no-reflow phenomenon,PCI with no-reflow phenomenon indicates the poor prognosis.

Journal of Chongqing Medical University 1986;0(03):-
Objective: To evaluate the diagnostic value of IL-6,IL-8,and TNF-? in malignant pleural effusion and tuberculous pleural effusion.Methods:We detected IL-6,IL-8,and TNF-? in malignant pleural effusion(21 cases)and tuberculous pleural effusion(13cases).Results:The mean values of the three cytokines measured in tuberculous pleural effusion were significantly higher than malignant pleural effusion( P
4.Treatment of renal tuberculosis complicated with active pulmonary tuberculosis
Journal of Chongqing Medical University 2003;0(05):-
Objective:To implove the level of diagnosis and treatment of renal tuberculosis complicated with active pulmonary tuberculosis.MethodsThe diagnosis and treatment of 28 cases with renal tuberculosis complicated with active pulmonary tuberculosis were analyzed.Results:88.2% of patients were negative in PPD test, and 55.6% positive in the sputum acid fast stain. All the patients except 4 received thetreatment of anti-tuberculosis continuosly for 3-6 months before surgery.Conclusion:It is necessary to treat the patients with anti-tuberculosis drugs and improve their immune function before proper surgical treatment.Patients in fair general condition could be operated on 2 weeks after anti-tuberculosis therapy.

Objective: To study the quality standard of Fangtuoshengfaling Lotion (Radix et Rhizoma Rhei, Radix Sophorae Flavescentis, Radix Polygoni Multiflori, Radix Angelicae Sinensis, Radix Astragali seu Hedysarion, etc.). Methods: Radix et Rhizoma Rhei, Radix Sophorae Flavescentis were identified by TLC. The content of 2,3,5,4′ tetrahydroxystibene 2 O ? D glucoside in Radix Polygoni Multiflori of lotion was assayed by HPLC. Results: The linearity of 2,3,5,4′ tetrahydroxystibene 2 O ? D glucoside was found in the range from 0.36~1.84ng. The average recovery was 96.866% and RSD =0.898%( n =5). Conclusion: The method was found to be simple, accurate and with a good reproducibility and may be used for the quality control of the Lotion.
7.Determination of 39 Polybrominated Diphenyl Ethers in Coastal Sediments by Ultrasonic Extraction Coupled with Gas Chromatography-Mass Spectrometry
Chinese Journal of Analytical Chemistry 2009;37(11):1627-1632
A method was developed for the determination of 39 polybrominated diphenyl ethers(PBDEs) from mono- to hepta-brominated in coastal sediment by gas chromatography/mass spectrometry. The sample was extracted with a solution of dichloromethane: n-hexane( 1:1,V/V) ,followed by ultrasonic extraction for 60 min at 25℃. The clean-up step was optimized using silica gel and alumina. The detection limit of the method was in the range of 0.003 - 0.10μg/kg. The results indicate that the average recovery of the internal standard was from 66.2% to 118. 6%. The relative standard deviation RSD( % ) was from 0. 8 % to 18. 2%. The method for the detection of 39 PBDE congeners in coastal sediment was sensitive,high reproducible with satisfactory recoveries.

10.Clinical value of preoperative biliary drainage for the outcomes of pancreaticoduodenectomy in the patients with jaundice caused by malignant obstruction hi the low bile duct
Clinical Medicine of China 2011;27(7):747-750
Objective To investigate the effects of preoperative biliary drainage ( PBD ) on the morbidity and mortality of pancreaticoduodenectomy in patients with malignant obstructive jaundice in the lower bile duct. Methods Clinical data of 74 cases undergoing pancreaticoduodenectomy from Jan. 2000 to Dec. 2005 with preoperative total bilirubin level over 85 μmol/L were collected and retrospectively analyzed. Comparison was performed between patients receiving PBD and those not. Before surgery. The parameters sincluding perioperative situation, in-hospital death rate, post-operative complications and were calculated to evaluate the influence of pre-operative biliary drainage on the outcomes. Univariate analysis and Logistic analysis were used to identify the risk factors for post-operative complications. Results Forty (40/74) cases received PTCD procedure. The total bilirubin was significantly reduced from (338. 10±88. 38 )μwnol/L to ( 228. 50±82.24) μ,mol/L in PTCD population and was significantly lower than ( 328. 60±93. 02) μmol/L of the non-PTCD group. There was no significance between the two groups in terms of total complications and individual complication Logistic regression analysis showed that preoperative TB over 340 μmol/L and blood loss over 600 ml were important risk factors for post-operative complications. Conclusion High pre-operative total bilirubin over 340 μmol/L increases the risk of post-operative complications in the patients with malignant jaundice. Preoperative biliary drainage is useful to reduce the total bilirubin and improve the hepatic function of the patients. Prolonged pre-operative biliary drainage could be considered in the patients with high preoperative bilirubin,poor nutritional condition and impaired coagulation to enhance the tolerance of surgery.
