Objective: To explore the clinical characteristics of ST elevation and non-ST elevation acute myocardial infarction (AMI) related with left circumflex artery (LCX) occlusion. Methods: Clinical data of 86 consecutively enrolled patients with LCX occlusion -related AMI undergoing percutaneous coronary intervention (PCI) were retrospectively analyzed. According to manifestations of electrocardiography, the patients were divided into ST elevation myocardial infarction (STEMI) group (n=32) and non STEMI (NSTEMI) group (n=54). Clinical features and prognosis were compared between two groups. Results: Compared with NSTEMI group, there were significant increase in serum level of creatinine [(80±23) μmmol/L vs. (100±30) μmmol/L], in rates of intra-aortic balloon counterpulsation (IABP)support (3.7% vs. 18.8%), usage of invasive respiratory machine (1.9% vs. 15.6%), ischemic mitral reflux (13.0% vs. 40.6%), complete atrioventricular block (0 vs. 9.4%), proportion of left coronary artery dominant type (7.4% vs. 28.1%) and left ventricular end-diastolic diameter [LVEDd,(46±4)mm vs.(48±5)mm?]; And significant decrease in percentage of triple-vessel coronary disease (72.2% vs. 46.9%) in STEMI group, P<0.05 or <0.01. There was no significant difference in mortality rate during admission (3.1% vs. 0, P>0.05) between STEMI group and NSTEMI group. Conclusions: Compared with patients with NSTEMI, patients with STEMI have poorer heart function in patients with left circumflex artery occlusion, which may be related to more left coronary dominance.

OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.
METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.
RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).
CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

Background and purpose:Liver cancer resection and splenectomy are the main methods to treat hepatocellular carcinoma and hypersplenism. The aim of this study was to discuss the safety and feasibility of simultaneous radiofrequency ablation (RFA) and laparoscopic splenectomy (LS) for the treatment of small hepatocellular carcinoma with hypersplenism.Methods:Twenty-seven patients with small hepatocellular carcinoma and cirrhotic hypersplenism underwent RFA and LS. The clinical data were also analyzed.Results:The surgery was converted to an open surgery in 1 patient, while laparoscopic splenectomy in a hand-assisted manner was performed in 2 patients. There were 31 liver tumors treated with RFA. Blood loss were 110-900 mL (mean=320 mL). Operation time were 72-127 min (mean=107 min). Subcutaneous emphysema occurred in 1 patient, and pancreatic leakage in another patient. Nine patients developed ascites. one patient suffered from massive haemorrhage, and emergency operation was adopted to stop bleeding. This patient recovered well after operation. No death was found during the hospitalization. Conclusion:Combining RFA with LS for the treatment of liver cancer and hypersplenism is minimally invasive, safe, and feasible.

AIM: To evaluate the changes of corneal high - order aberration (including Coma, Spab, RMSh) after laser in situ keratomileusis (LASIK) with femtosecond laser, sub- Bowman keratomileusis ( SBK ) and laser epithelial keratomileusis (LASEK). METHODS: Of 82 myopic patients ( 164 eyes ), 31 patients (62 eyes) were treated by FS-LASIK, 31 patients (62 eyes) were treated by SBK, 20 patients (40 eyes) were treated by LASEK. Sirius system was used for measuring the coma aberration, spherical aberration, and high order aberration at 1, 15d,1, 3mo after surgery. RESULTS: 1) Vision: The uncorrected visual acuity of the three groups had no differences (P>0. 05). 2) Corneal aberrations: Three kinds of surgical procedure for patients with corneal aberration had significant impact. The C7, C8, C12 and RMSh of three groups were increased significantly (P<0. 05). The C7, C8, C12 and RMSh were not recovered to preoperative levels after 3mo. But the increase of patients after FS- LASIK was smaller than the other two groups, with statistical significance (P<0. 05). CONCLUSION: Compared with SBK and LASEK, FS - LASIK has better visual acuity in the early postoperative and corneal higher-order aberrations increase is relatively small.

Objective To evaluate the clinical efficacy and safety of domestic Sirolimus-eluting stents (Firebird) and imported Zotalimus-eluting stents ( Resolute) in the treatment of patients with unprotected left main coronary artery disease ( ULMCA) . Methods We retrospectively enrolled 76 patients with ULMCA treated by percutaneous coronary intervention (PCI) under the guidance of IVUS in our hospital. According to the different stents used in the procedure, the patients were divided into two groups: Domestic Sirolimus-Eluting Stents group (Firebird group, n = 42) and Imported Zotarolimus-Eluting Stents group (Resolute group, n = 34) . We analyzed the baseline characteristics, coronary artery lesion characteristics, stenting strategies and any changes in left ventricular ejection fraction ( LVEF) in both groups and investigated the long-term clinical outcomes. Results There were no significant differences in the baseline characteristics, the SYNTAX scores of the coronary artery lesion and the rate of complete revascularization between the two groups. Compared with that in Firebird group, there were more cases involving the distal left main (79. 4% vs. 45. 2% , P ﹤ 0. 05) and more patients using two stents strategies (29. 4% vs. 7. 1% , P ﹤ 0. 05) in the Resolute group. The change in LVEF post-PCI had no difference between the two groups. The patients were followed up for a mean of (23. 3 ± 10. 7) months. During the follow-up period, the occurrence of MACCE had no significant difference between the two groups. In the Firebird group, there were one sudden cardiac death, one nonfatal myocardial infarction, one stroke and five patients with recurrence of angina pectoris. In the Resolute group there were one sudden cardiac death, one target lesion revascularization and four patients with recurrence of angina pectoris. Conclusions Compared with the imported Zotalimus-Eluting Stents, the domestic Sirolimus-Eluting Stents are safe and effective in the treatment of patients with unprotected left main lesions under the guidance of IVUS. The two kinds of stent showed similar long-term clinical outcomes.
