OBJECTIVETo study therapeutic effects between hook plate fixation and modified Weaver-Dunn surgery for the treatment of acromioclavicular joint dislocation.

METHODSForty patients with fresh acromioclavicular joint dislocations of type III according to Rockwood classification were reviewed. All the patients were divided into two groups: hook plate fixation group and modified surgery group. There were 20 patients in hook plate fixation group, including 13 males and 7 females, with an average age of (37.45 +/- 14.29) years old; 12 patients had injuries in the left and 8 patients had injuries in the right; preoperative Constant-Murley score was 40.75 +/- 10.40. And there were 20 patients in modified surgery group,including 11 males and 9 females, with an average age of (41.65 +/- 14.83) years old; 11 patients had injuries in the left and 9 patients had injuries in the right; preoperative Constant-Murley score was 42.75 +/- 8.18. The Lazzcano standard, Constant-Murley score and imaging changes were used to evaluate shoulder joint function before and after surgery.

RESULTSAll the patients were followed up,and the duration ranged from 7 to 32 months,with an average of 24 months. According to Lazzcano evaluation, 16 patients got an excellent result,3 good and 1 poor in modified surgery group with no re-dislocation, and 1 patient had pain more than middle degree; while in hook plate fixation group, 9 patients got an excellent result, 7 good and 4 poor, 1 patient had re-dislocation, and 3 patients got pain more than middle degree. The therapeutic effects of modified surgery group were better than those of hook plate fixation group. Constant-Murley scores:preoperative 42.75 +/- 8.18 vs 93.40 +/- 4.04 at the latest follow-up in modified surgery group; preoperative 40.75 +/- 10.40 vs postoperative 88.40 +/- 4.81 and 92.05 +/- 4.49 at the latest follow-up in hook plate fixation group. The postoperative scores all improved compared to preoperative scores in two groups. And there was no statistical difference of scores at the latest follow-up between two groups.

CONCLUSIONThe surgery of allograft tendon transplantation combined with anchor fixation to strengthen coracoclavicular ligament, as well as part transposition of acromiocoracoid ligament and resection at the distal part of clavicle may got safety fixation and less postoperative complications compared with hook plate internal fixation.

Objective To evaluate the clinical significance of serum levels of ProGRP, TPS and NSE in diagnosis and therapy monitoring in small cell lung cancer patients. Methods The levels of serum ProGRP, TPS and NSE in 51 SCLC patients (SCLC group), 60 benign pulmonary disease patients (benign disease group ) and 60 healthy people (healthy group ) were determined using chemiluminescent immunoassay, ELISA and electrochemiluminescent immunoassay respectively. Blood samples were collected and detected prior to therapy, before the second course of chemotherapy and the third course of chemotherapy consecutively in all the 51 SCLC patients. Results The serum ProGRP, TPS and NSE concentrations prior to chemotherapy in limited stage SCLC (LSCLC) were 136. 9(22.8-631.7)ng/L, 78. 2(56.4-114.6) U/L and 28.1(20.9-46.1)μg/L, respectively; And in extensive stage SCLC patients (ESCLC) were 1 106.6(41.2-2161.1) ng/L, 230. 9( 143.5-259.0) U/L and 81.1 (34.3-140.0)μg/L, respectively. The serum concentrations of the 3 markers in benign disease group were 19. 7 ( 9. 5-29. 1 )ng/L, 48. 7 ( 17.9-95.4) U/L and 12. 1(1.2-13.9) μg/L; and in healthy group were 20.3(10.7-30.6) ng/L, 50.3(19.5-70.7) U/L and 11.7 (1.1-13.4)μg/L, respectively. The Kruskal-Wallis test showed significantly statistical difference in different groups of the 3 tumor markers, Chi-Square were 51. 368,36. 532 and 81. 645( P ＜0. 01 ). Significant statistically differences showed when the concentrations of the 3 marks of the 2 control group were compared with that of the LSCLC group ( U =491, 827, 609 and 476, 831, 585,respectively, P ＜ 0. 05 ). Differences were also statistically significant when the 2 control group compared with that of the ESCLC group ( U = 314,532,456 and 302,553,430, respectively, P ＜ 0. 01 ). The AUC of ProGRP was 0.832 +0.029(95% CI:0.774-0.890). When cutoff value of ProGRP set as 37.7 ng/L, the diagnostic sensitivity, specificity, positive predictive value, negative predictive value and Youden's index were 71% (36/51), 97% (116/120), 90% (36/40), 89% ( 116/131 ) and 67%, respectively; show good detection performance. The sensitivity increased to 92%, 86%, 92% and 88%, when combination detection of ProGRP + TPS + NSE, ProGRP + TPS, ProGRP + NSE and TPS + NSE were used, and the specificities were 77%, 77% , 92% and 77% accordingly. The Fridman test showed significantly statistical difference in the 3 tumor markers at different stages of treatment, x2 were 49. 120, 10. 614 and 44. 392, P ＜0. 01. After the first chemotherapy course, all the tumor marker levels except TPS decreased significantly in comparison with the pretreatment concentrations. However, only ProGRP levels showed a progressive drop during the two consecutive courses of therapy, and the median concentrations were 68.0 ( 18. 6-158.4 ) and 21.0( 14. 9-63.5) ng/L (compared to the level before therapy,Z=-4. 889 and -5. 594, P ＜0. 01 ). The median of serum TPS increased slightly to 105.2 (54. 1-181.2 ) U/L after the first chemotherapy course (Z=-1.248, P＞0.05), and decreased significantly to 79.0(48.7-155.3) U/L after the second chemotherapy course (Z=-2.484, P＜0. 05 ). As to the NSE, the median concentration decreased to 11.8(8.0-16.0)μg/L after the first chemotherapy course ( Z= - 5. 568, P ＜ 0. 01 ). However, the median was 10. 6(9.0-12.7)μg/L, which showed no significant decrease after the second chemotherapy course (Z=-1.851, P＞0.05).Forty-six SCLC patients evaluated as clinical remission ( 3 CR and 43 PR) after the second chemotherapy course, among them there were 38 patients (83%) with normal serum ProGRP, TPS and NSE level ( 19 patients) or with only 1 abnormal tumor level ( 19 patients). There were only 2 patients with all abnormal serum ProGRP, TPS and NSE level, and both patients were evaluated as clinical PD. Two patients with 2 abnormal tumors results were classified as SD, the only 1 patient without therapy evaluation also had 2 abnormal tumor marker results. Conclusions The serum ProGRP, TPS and NSE are valuable tumor markers for diagnosis and treat monitoring of SCLC, particularly the ProGRP + NSE shows the highest clinical value. Combing detection of the 3 tumor markers are valuable for therapy monitoring and prognosis in SCLC patients.

Objective: To evaluate the impact of intracoronary administration of eptifibatide oncoronary no-reflow and myocardium perfusion in patients with ST-elevation myocardial infarction (STEMI) at percutaneous coronary intervention (PCI). Methods: A total of 80 STEMI patients with emergent PCI were randomly divided into 2 groups: Eptifibatide group, the patients received intracoronary administration of eptiifbatide and Control group, the patients received the same volume of normal saline.n=40 in each group. The baseline condition, post-operative vascular recanalization, changes of platelet aggression at pre- and post-medication were compared between 2 groups. Echocardiography was examined at immediately and 24 weeks after operation;myocardial infusion imaging was examined at l week after operation. All patients were followed-up for 24 weeks to observe the incidence of major adverse cardiovascular events (MACE). Results: Compared with Control group, Eptifibatide group showed increased ratios of post-operative TIMI grade 3 (72.5%vs 92.5%) and myocardium perfusion (70.0% vs 90.0%), bothP<0.05; decreased post-operative and 2h post-medicinal platelet aggression and they were both lower than Control group at the same period, allP<0.05. Eptiifbatide group had obviously improved LVEDD and LVEF at 24-week than 1-week after PCI and they were both superior to Control group, allP<0.05. There were 7 (17.5%) patients in Eptiifbatide group and 7 (7.5%) in Control group suffering from small bleeding events, P>0.05; no severe bleeding eventand no in-hospital thrombocytopeniaoccurred. MACE occurrence rates during 24-week follow-up period were 12.5% vs 22.5%, P>0.05. Conclusion: Intracoronary administration of eptiifbatide in STEMI patients at emergent PCI could effectively improve coronary blood lfow,increase myocardium perfusion and enhance cardiac function without severe bleeding events.
