Objective　To evaluate the diagnosis and tre atment of testicular torsion.　Methods　18 cases of testic ular torsion were reviewed and reported.　Results　The tes ticles of 5 cases with short time or incomplete torsion were salvaged by operati ve detorsion.The testicles of 13 cases with testicular necrosis were removed (re moval rate 70%).　Conclusions　Testicular torsion has to b e diagnosed correctly on time and the detorsion has to be performed early.For di agnosis of testicular torsion color-Doppler ultrasonography image is a reliable method.Preventive orchiopexy has to be performed in order to avoid recurrence o r relapse.

Objective To explore the clinical application of array comparative genomic hybridization (aCGH) and karyotype a-nalysis in the prenatal evaluation of fetal with small supernumerary marker chromosome (sSMC) .Methods One case was indenti-fied with de novo small supernumerary marker chromosome .G-banding analysis indicated that the fetus had a karyotype of 47 , XY ,+Mar .aCGH was used to define the precise location and size of de novo chromosome .Results aCGH revealed that there was 2 .03 Mb duplication from 15q11 .1-q11 .2 in the fetus .aCGH revealed the presence of small supernumerary marker chromosome . Conclusion The technologies of aCGH can be used for identifying the origin of small supernumerary marker chromosome and defi-ning the loci of the chromosome .Combined with the karyotype analysis ,it can be applied to genetics analysis and prenatal diagnosis .

With Indian ink vasoperfusion and microangiography,the vessel rebuilding in fresh xenogenic bone graft of 33 rabbits,which had been given glucocortiocoid for a short period of time has observed.The results were as follows:(1)The vessel rebuilding ofxenogenic bone marrow was formed by the hostbone vessel growing in, however,that of the compact bone was formed by the inward penetration of the vessels from the host periost.(2)with glucocorticoid having been used for a short period of time,the vessel rebuilding rate was almost the same between fresh xenogenic bone and autogenic bone.(3)Vessel invasion which happened before osteogenesis regulated osteogenic action. The vessel invasion of different or- igins and under different conditions may have different influence on osteogenesis and osteolysis.

Objective To provide references for clinical rational use of Chinese patent medicine. Methods Totally 387 specifications of Chinese patent medicine in our hospital were analyzed, and were judged by pregnancy contraindication according to China Pharmacopeia (2010 edition). Results The 387 Chinese patent medicines involved 32 prohibited pregnancy ingredients, 1 taboo ingredient. In 89 Chinese patent medicines contraind prohibited ingredients, 33 marked prohibited ingredients, 18 marked contraindicated ingredients, 14 marked cautious ingredients, and 24 marked without-contraindication ingredients. 68 Chinese patent medicines contained pregnancy contraindication labels but without prohibited ingredients. Conclusion A unified standard of pregnancy contraindication should be established;researches on pregnancy contraindication should be strengthened;medicine specifications should be standardized and perfected.

Objective To investigate the application value of high-sensitivity troponin T (hs-cTnT)in acute coronary syndrome (ACS).Methods Serum hs-cTnT,CK and CK-MB were detected 198 patients with chest pain including 105 cases of acute myocar-dial infarction(AMI)and 93 cases of unstable angina(UA),and 83 cases of healthy physical examination as control.Results The positive rates of hs-cTnT,CK and CK-MB in the patients with diagnosed AMI were 88.6%,48.6% and 71.4% respectively,which were significantly higher than those in the patients with UA and the healthy controls(P <0.05 ).The positive rate of hs-cTnT in early AMI patients was higher than that of CK and CK-MB.Conclusion Compared with CK and CK-MB in myocardial Zymogram, hs-cTnT has very high sensitivity and specificity for diagnosing myocardial injury,could reduce the misdiagnosis and missed diagno-sis of ACS and is a marker for diagnosing the myocardial injury in early ACS.

Objective To evaluate the clinical significance of monitoring of D‐dimer ,fibrinogen and fibrin degradation products after hip replacement for diagnosing and preventing the lower extremity deep venous thrombosis .Methods A total of 66 cases of patients who carried out hip replacement from April 2013 to April 2015 in the department of orthopaedic in this hospital were se‐lected .Patients complicated with lower extremity deep venous thrombosis were enrolled into the observation group ,while patients without lower extremity deep venous thrombosis were enrolled into the control group .Levels of D‐dimer ,fibrinogen and fibrin deg‐radation products were strictly monitored after hip replacement and were comparatively analysed .Results There were no statisti‐cally significant differences in levels of fibrinogen and fibrin degradation products between the two groups (P>0 .05) ,while statisti‐cally significant difference was found in level of D‐dimer between the two groups(P<0 .05) .Conclusion The monitoring of D‐di‐mer ,fibrinogen and fibrin degradation products after hip replacement could have clinical significance for diagnosing and preventing lower extremity deep venous thrombosis .

Objective To evaluate the effects ofYinhuangdecoction and external application ofXilei decoction in treating vesicular stomatitis.Methods From January 2012 to October 2013, 126 enrolled cases were randomly divided into a treatment group and a control group with 63 in each. The treatment group, which was treated with acycloguanosine tablets as the control group did, was additionally given orallyYinhuang decoction and external application ofXilei decoction. The symptoms, clinical effects comparison were observed before and after the treatment.Results After 7-days treatment, the cure rate of the treatment group was 95.2%(60/63), and the control group was 73.0%(46/63). Their difference was conspicuous(χ2=17.407,P<0.05). The treatment group attained better curative effects(P<0.05) and got shorter symptomatic relief time of the duration of fever, time of tain disappeared, time of ulcer dissipated and cure time(The T-value is respectively 9.590, 6.983, 5.864, 5.814,P<0.01).ConclusionsYinhuang decoction and external application ofXilei decoction is effective for treating vesicular stomatitis.

Objective To investigate the expression and clinical significance of high-sensitivity C-reactive protein(hs-CRP) and interleukin-6 (IL-6) in patients with recurrence of atrial fibrillation(AF) after radiofrequency catheter ablation.Methods Retrospective analysis was made among a total of ninety-seven cases of paroxysmal atrial fibrillation treated by radiofrequency catheter ablation in Chaoyang Central Hospital from January 2011 to December 2015.The patients were divided into recurrent group and successful group,depending on whether they had recurrence in six months after radiofrequency catheter ablation.The concentration of the patients'' serum hs-CRP and IL-6 before radiofrequency catheter ablation were detected and compared with those of the healthy subjects (control group) during the same period.Logistic regression analysis was used to analyze the risk factors in atrial fibrillation recurrence after radiofrequency catheter ablation.Results The levels of serum hs-CRP was (4.6±1.2) mg/L and IL-6 was(0.19±0.05) mg/L in the recurrent group,higher than those in the control group ((2.0±0.3) mg/L,(0.10±0.03) mg/L).The differences between the two groups were statistically significant (P=0.037,0.046).According to the atrial fibrillation recurrence,97 patients were divided into recurrent group (29 cases) and successful group (68 cases).The levels of serum hs-CRP and IL-6 in the recurrent group were (5.61±2.30) mg/L,(0.30±0.07) mg/L,respectively,while the data of the successful group were (3.29±1.62) mg/L,(0.15±0.06) mg/L,respectively.There were significant differences between the two groups (P=0.047,0.036).Logistic regression analysis showed that the left ventricular anterior and posterior diameter (OR=2.073,95%CI:1.078~4.126,P=0.031),levels of serum hs-CRP (OR=1.943,95%CI:1.025-3.698,P=0.042) and serum IL-6 (OR=2.071,95%CI:1.089-10.101,P=0.027) were all risk factors in atrial fibrillation recurrence after radiofrequency catheter ablation.Conclusions Inflammatory factors might be involved in the occurrence and maintenance of atrial fibrillation.The expression levels of serum hs-CRP and IL-6 are related to the recurrence of AF,which could be independent predictors of postoperative atrial fibrillation recurrence.
