0.05, all statistically insignificant. Conclusions: Primary PCI was equally effective for the treatment of one vessel and multivessel AMI patients.

[Objective]To compare the immediate therapeutic effects of the treatment of gluteal muscle constracture(GMC)with arthroscopic release of contractured tissue and conventional surgery.To investigate the indications of arthroscopic surgery.[Method]Ninty-six limbs of 48 patients with traditional surgery and 84 limbs of 42 patients with arthroscopic surgery were analyzed in terms of operation time,length of the incision,postoperative pain,complications,the time of exercise,postoperative hospital stay and one-year recurrence rate.[Result]Arthroscopic surgery group had smaller incisions,earlier exercise,less postoperative pain and shorter hospital stay than conventional surgery group,but the two groups showed no significant difference in operative time,complications,effects of operation and one-year recurrence rate.[Conclusion]Arthroscopic release of contracture tissue is a safe,effective,economical and cosmetic way to treat the gluteal muscle contracture.This method is worthy of wide promotion.

Objective\ To investigate the possible mechanism of fasicular ventricular tachycardia(FVT).Method\ Ten cases of FVT with different ECG manifestion and treatment were analysed.Of the 10 cases,8 exhibited LAD and 2 RAD.Ablation was performed on 5 cases;3 cases were treated with verapamil,1 case with lidocaine;in another case ventricular rate was 68bpm,and ventricular escape rhythm was considered.One case exhibited Wenckenbach conduction.Reentry seemed unlikely in these 2 cases.Result\ Reentry was the basis in most cases of FVT,but in some,enhanced automaticity could be the underlying mechanism.

AIM: To explore the effects of hyperbaric oxygen (HBO) therapy on language function of aphasics and it's mechanisms. METHODS: Forty patients with aphasics after mild and moderate cerebral trauma and stroke were chosen and divided into therapy group (20 patients) and control group (20 patients). All the patients in both groups received routine therapy.Besides routine therapy, patients in therapy group also received HBO therapy. The HBO treatment contained three courses, each lasts for 15 days at an interval of 3 days. The language functions ( including 11 sub - items) were tested with the Apparatus ZM2.1for Diagnosis and Treatmern of Language Disorders (Language Disorders ZM2.1) before and after each course of HBO and be compared between the two groups. RESULTS: The therapeutic effects between the therapy group and the control group: the scores of 10 sub- items are significantly higher than those of the control group after the 2nd course (P＜0. 05); After the 3rd course, all 11 sub - items were improved significantly ( P ＜ 0.05). The therapeutic effects before and after each course of the therapy group:the scores of the advanced dictation, voice expression and semantic expression increased significantly after the 1st and the 2nd course ( P ＜ 0.05). CONCLUSIONS: The HBO therapy might facilitate the recovery of the language function of the aphasics by promoting the recovery and the self- reparation of the neurocytes and alleviating the focal ischemia - reperfusion. The result of this effect would facilitate the original recovery velocity and not be focused on some language functions and much more obvious in the 1st and the 2nd course.

Objective To explore the methods of improving diagnosis correctness between the patients with prostate cancer and benign prostatic hyperplasia.Methods Totally 87 patients with benign prostatic hyperplasia or prostate cancer which confirmed by MRI and prostate biopsy for the PSA significantly increased in our hospital from July 2013 to March 2016 were collected.By using the three methods of the PI-RADS V2 score,the T2WI+DWI/ADC+DCE-MRI+MRS and PI-RADS V2 score+MRS to diagnose,and comparing with the pathology results,the diagnostic consistency of the two physicians were analyzed.The sensitivity,accuracy and specificity of three ways were compared,and the correlation between PI-RADS V2 score and Gleason score were calculated.Results The diagnostic consistency of the two physicians:PI-RADS V2 score,K=0.951;T2WI+DWI/ADC+DCE-MRI+MRS score,K=0.838;PI-RADS V2+MRSI score,K=0.937.The correlation between PI-RADS V2 score and Gleason score,r=0.871,P=0.001 4;diagnostic sensitivity,specificity and accuracy of PI-RADS V2 score were 77.3％,74.4％,75.9％;diagnostic sensitivity,specificity and accuracy of T2WI+DWI/ADC+DCE-MRI+MRS were 88.6％,76.7％,82.8％;diagnostic sensitivity,specificity and accuracy of PI-RADS V2+MRSI score were 86.4％,81.4％,83.9％,respectively.Conclusion Compared with the traditional diagnostic methods,the combination of new prostate report and data system and MRSI can improve the diagnostic accuracy of prostate cancer and benign prostatic hyperplasia.The PI-RADS V2 score is more objective and accurate in the description of the lesion,but the low signal of benign hyperplastic nodules in transitional zone should be dialogued carefully through a variety of image parameters.

Objective To investigate the changes of airway resistance before and after Bronchial Diulation Test in patients with senile asthma and the effect of age on the degree of airway resistance. Methods A total of 29 (> 60 years)senile asthma patients and 21 younger(< 60 y)patients were enrolled in the study. The status of their pulmonary function was determined by MEFV(Maximum expiratory flow?volume curve)and an IOS(impulse oscillometry) system before and after Bronchial Diulation Test,The spirometric indexes such as forced vital capacity,total respiratory impedance,respiratory resistance and respiratory system reactance were collected and analyzed. Results Significant decreases of indexs were found after Bronchial Diulation Test compared with those before Bronchial Diulation Test in the study group(P<0.05,respectively). No significant difference in improvement of indexs was found between the group of patients with senile asthma(age > 60 years)and the group of healthy control(age < 60 years ). Each index of the airway resistance has a very good correlation with FEV1%,with the highest degree of relation is X5%. Conclusion The airway resistance of senile asthmatic patients was significantly improved after diuslation test and these indexes IOS would be valuable in evaluating the changes of airway resistance of senile asthma.

BACKGROUND:Young patients with cruciate ligament injury and high activity levels are prone to grade III medial colateral ligament injury in knee joint. Conventional construction methods such as direct restoration of injured ligaments and muscle-tendon transposition may induce the loosening of medial colateral ligament complex. OBJECTIVE:To explore the clinical effect of autologous tendon transplantation for grade III medial colateral ligament injury of the knee joint. METHODS: Forty-seven patients with grade III medial colateral ligament rupture were treated by operative repair and reconstruction. After repairing the anatomical structure of medial colateral ligaments, we liberated organic semitendinous tendon, bone-patela tendon-bone, and hamstring tendon, to reconstruct superficial medial colateral ligament. RESULTS AND CONCLUSION:Thirty-seven patients were folowed up for 48 months. Preoperative Lysholm score, IKDC score, Tegner score at the final folow-up, and the widened medial joint space on valgus stress X-Ray films were significantly improved compared with before reconstruction (P < 0.05). According to clinical efficacy scores, 12 cases achieved excelent reconstruction, 18 cases achieved good reconstruction, 4 cases achieved moderate reconstruction, and 3 cases achieved poor reconstruction. The excelent and good rate was 82%. Medial colateral ligament reconstruction based on repairing the anatomical structure is effective and satisfactory. Autologous bone-patela tendon-bone or semitendinous tendon is a good choice for medial colateral ligament reconstruction.

Objective Cervical lymph node enlargement may be attributed to inflammation or tumors .This study was to analyze the pitfalls in fine-needle aspiration cytology ( FNAC) of cervical lymph nodes and the measures for avoiding misdiagnosis of cervical lymph node lesions . Methods We retrospectively analyzed the data about 435 cases of FNAC in comparison with the results of corre-sponding tissue biopsies in cervical lymph nodes . Results Among the 435 cases, 7 showed disagreement between the results of cytolog-ic and histologic diagnoses, which included 5 males and 2 females, at the age of 41 to 71 (58.4 ±8.9) years.Six of the cases presented with local lymph node enlargement and 1 with generalized lymphadenopathy, all with enlarged lymph nodes palpable 1-4 cm in diameter . Based on the results of FNAC, 1 case of malignant lymphoma was misdiagnosed as lowly differentiated adenocarcinoma, 1 case of lympho-ma misdiagnosed as poorly differentiated metastatic carcinoma, 2 cases of lymphoma diagnosed as lymphoproliferation and recommended for biopsy, 1 case suggestive of malignant tumor without further classification, and 2 cases microscopically characterized and recommended for lymph node biopsy.Compared with the results of the biopsy, FNAC achieved a 99.3%coincidence rate of qualitative diagnosis (432/425), with a misdiagnosis rate of 1.6%(7/435). Conclusion FNAC plays a very important role in the initial identification of the nature of lymph node lesions and the type of tumors.Practiced puncture skills and intimate knowledge about the histopathological features, diagnostic criteria, and differential diagnosis of the lymphatic system disorders are essential for improving the diagnostic accuracy of FNAC .
