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 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.

Chinese Journal of Radiology 2013;47(9):820-823
Objective To assess the role of MRI in the preoperative characterization and local staging of testicular neoplasms.Methods A retrospective study of 24 patients suspected of testicular neoplasm was conducted.The histological diagnosis of testicular neoplasms was made and local extension of testicular malignancy was evaluated.The MRI findings were correlated with the pathologic results.Results Histological examination revealed 26 intratesticular lesions,14 of which were nalignant,including 4 cases of diffuse large B cell lymphoma,7 cases of seminoma,2 cases of embryonal carcinoma,one case of teratoma.Twelve lesions were benign,including 5 cases of epidermoid cyst,2 cases of simple cyst,2 cases of inflammatory granuloma,2 cases of testicular mediastinal tubular expansion and one case of testicular pseudo fibroma.Six malignant testicular tumors were confined within the testis,4 invaded the testicular tunicae or epididymis,2 invaded the spermatic cord,and 2 invaded the scrotal wall.The accuracy of MRI in the diagnosis of intratesticular lesions was 92%.The accuracy of MRI diagnosis in the local staging of testicular tunors was 86%.Conclusions MRI is highly accurate in the preoperative characterization and local staging of testicular neoplasms.It is of great significance to the clinical diagnosis and treatment.

8.Application of Care kV combined with Care Dose 4D in abdominal CT
Chinese Journal of Radiological Medicine and Protection 2017;37(1):68-72
Objective To study the application of the intelligent optimum tube voltage ( Care kV) combined with automatic tube current ( Care Dose 4D) technique in dual source CT scanning for the abdomen .Methods 180 adult patients underwent whole abdominal CT examination from February 2016 to March 2016 of were selected as the retrospective research objects .On the basis of reference mAs of the image quality the patients were divided into three groups using completely randomized grouping method with 60 patients in each group, such as 250 mAs group, 200 mAs group, and 150 mAs group.The other scanning parameters and image reconstruction parameters were the same .The liver parenchyma CT values and image noise( SD) at the second hepatic portal level were measured .The signal-to-noise ratios ( SNR) in the three groups were compared as well as contrast to noise ratio ( CNR ) , noise ( SD ) , the average volume CT dose index (CTDIvol), dose length product (DLP) and effective dose(E).Results The kV and mAs values in the plain scan , arterial phase scan and portal phase scan in the three groups of patients had statistically significant differences(F=35.25, P<0.05).With the reducing of the refference mAs, the frequency of choosing lower kV in three groups of patients increased gradually .The CTDIvol, DLP and E of plain scan, arterial and portal phase in three groups of patientshad significant difference (F=31.51, P<0.05).With the decline of the reference mAs, the radiation dose decreased gradually , with 150 mAs group lowest.The SNR, CNR and noise of three phases in 250 mAs group and 200 mAs group had no statistically significant difference (F=1.61, P>0.05).In 250 mAs group and 150 mAs group, the SNR and the noise of plain scan and arterial phase images had no statistically significant difference ( F=1.98, P>0.05) , and SNR of portal phase images and CNR of three phases had statistically significant difference (F=27.64, P<0.05);In group 200 mAs and group 150 mAs, the SNR, CNR and noise of plain scan and arterial phase images had no statistically significant difference (F=1.95, P>0.05), and the SNR and CNR of portal phase images had significant difference (F=19.63, P<0.05).Conclusions For the combined use of Care kV and Care dose 4D,it is feasible to select appropriate reference mAs in reducing radiation dose without sacrificing imaging quality .

Chinese Journal of General Surgery 1993;0(03):-
ObjectiveTo study the effect of fibrin glue(FG) and growth hormone(GH) on the anastomosis of the small bowel at peritonitis. MethodsResection and anastomoses of the small bowel at peritonitis was performed in rats. In group N:normal control;in group A:a standard anastomosis was constructed with 12 silk sutures;in group B:an incomplete anastomosis was constructed with only 4 silk sutures;in group C: incomplete anastomosis+FG;in group D: incomplete anastomosis+GH;in group E: incomplete anastomosis+FG+GH.On days 1,3 and 5,ten rats in each group were sacrificed.The healing of anastomosis were evaluated,the anastomotic bursting pressure and hydroxyproline concentration were measured. Results In group A the bursting pressure was low from day 1 to day 3(18?10?mm?Hg and 36?11?mm?Hg each).The percent of false-healing was 30%,significantly higher than group N.The bursting pressure in group C was significantly higher than in group A(32?7?mm?Hg and 65?9?mm?Hg each),the healing of the anastomosis was significantly improved,the percent of false-healing was 11.7%.Hydroxyproline concentration of each group showed no differences. Conclusion Fibrin glue helps the healing of the anastomosis of the small bowel at peritonitis in rats,and can protect it from complications. The addition of GH does not improve healing.

Chinese Pharmacological Bulletin 1986;0(06):-
AIM To study the effect of Topotecan(TPT) on cell cycle and apoptosis of hunman lung cancer SPC A 1 cells and the role of Caspase 3 and bcl 2 involved in TPT induced apoptosis. METHODS Cells were incubated with TPT(5,10,15 and 20 mg?L -1 ) for 24 h. Apoptosis was detected by TUNEL staining, electronic microscope and DNA agarose gel electropheresis. Flow cytometer was used to analyse cell cycle changes and to detect apoptotic rates and bcl 2 expression of cells treated with TPT or TPT and 50 ?mol?L -1 Ac DEVD CHO(specific Caspase 3 inhibitor). RESULTS Apoptosis of cells treated with TPT(5 mg?L -1 ) was not detected, but apoptosis rates increased with the increase of TPT concentration and there was significant difference between each concentration group( P
