Objective To estimate the clinical efficacy of naloxone and trimetazidine in the treatment of severe viral myocarditis.Methods40 patients with severe viral myocarditis were randomly divided into two groups: control group(20cases) and treatment group(20 cases).All patients in control group and treatment group received conventional therapy.In adition,the patients in treatment group received naloxone and trimetazidine treatment.After 14 days,the changes of clinical symptoms were observed.In addition,serum creatinine kinase(CK)-MB and cardiac troponin I(cTnI) levels were measured.ResultsAlthough the symptoms,CK-MB and cTnI were significantly improved in two groups,but significant difference was still found between control group and treatment group(P

Objective To investigate the variation of lipid profile in patients with acute myocardial infarction (AMI) of different age groups.Methods Total 1214 patients of AMI were admitted to our hospital from May 2007 to July 2011.The age of patients ranged 40-89 years,and patients were divided into 5 age groups with 10-years step.Differences in lipid levels were observed by using pair-wise comparison among different age groups.Results Pair-wise comparisons among different age groups indicated that TC levels were higher in 40-69 years age groups [(4.71 ± 1.08),(4.80 ± 1.30),(4.69 ± 1.03) mmol/L,respectively] than those in the 70-89 age groups [(4.41 ± 0.96),(4.38 ± 1.03) mmol/L],all P ＜ 0.05(t values were 2.381,2.323,4.382,3.965,3.317,3.096).TG levels among three age groups ＜ 59 years had no significant difference,which were higher than those in groups over 60 years.Among 50-89 years age groups,TG gradually reduced with increase of age.HDL levels were lower in 40-59 years age groups [(1.03 ± 0.23),(1.05 ± 0.26) mmol/L,respectively] than those in 60-89 years age groups [(1.11 ±0.28),(1.11±0.28),(1.16±0.34) mmol/L,respectively],allP＜0.05 (t values were-2.777,-2.789,-3.731,-2.543,-2.566,-3.644).Total cholesterol (TC) (r =-0.123,P ＜0.01),lowdensity lipoprotein cholesterol (LDL) (r =-0.139,P ＜ 0.01) and triglyceride (TG) (r =-0.287,P ＜0.01) were negatively but high-density lipoprotein cholesterol (HDL) (r =0.125,P ＜ 0.01) was positively correlated with age of patients.TC levels in female patients were higher than those in male patients in 50-89 years age groups; LDL levels in female patients were higher than those in male patients in 50-69 years age groups and HDL levels in female patients were higher than those in male patients in 40-79 years age groups (all P ＜ 0.05,t values were-2.878,-3.007,-3.352,-3.333).Conclusions Results show that the non-elderly AMI patients (＜60 years) have higher levels of TC,LDL and TG,and lower level of HDL than the elderly patients; the TC,LDL and HDL levels are higher in female AMI patients than those in male patients at the same age groups.

· AIM: This study was designed to evaluate the effectiveness of anterior lens capsule inclusion in combined trabeculectomy and cataract surgery in preventing scar formation of the filtering bleb in rabbit model.· METHODS: Twerty-Four eyes (12 rabbits) with glaucoma model were studied, anterior lens capsule inclusion in trabeculectomy with the small-incision cataract surgery were performed on all right eyes (experimental group) and no implants were applicator in trabeculectomy with the small-incision cataract surgery on all left eyes (control group). These operated eyes were followed up from day 1 to 6 months postoperatively. Intraocular pressure (IOP) was measured and filtering blebs were observed after surgery. Other main outcome measures: cornea、conjunctiva、formation of the anterior chamber, anterior chamber depth、inflammatory reaction、achievement ratio of operation and complications were analyzed. On week 1, 2, 4, 12 and 24 after surgery the animal were killed in batch. Tissue was harvested from the bleb area and was made pathological section. HE staining、light microscope and micro photo analysis technique were applied to observe the cytological and histopathologic characteristics of the filtering tunnels.· RESULTS: There were significant differences between the two groups on IOP (1, 2, 4 weeks)、filtration bleb, achievement ratio of operation and complications. In experimental group, at the first month postoperatively, anterior lens capsule absorption started with inflammatory characteristics. The peak of inflammatory reaction occurred 1 week after operation and all the cells in the filtrating tunnel disappeared 6month after surgery. The fibroblast proliferation in control group occurred at I week and the filtrating tunnel closed with angiogenesis at 1 month after surgery. Fibroblast proliferation started 1week after surgery with no statistical difference during the time course (P ＞0.05). Significant statistical differences were observed by comparing the fibro blasts numbers per unit area in the filtrating tunnel in experimental group and those in control groups (P＜0.05).· CONCLUSION: Anterior lens capsule was totally absorbed at 6 months postoperatively. Anterior lens capsule inclusion in trabeculectomy with cataract surgery can possibly control intraocular pressure effectively, long-term sustainability of functional filtration bleb, inhibition of the proliferation of fibroblasts and opening of the filtrating pathway in the experimental animal models were satisfied. Compared to the control group, anterior lens capsule application has less complication.

OBJECTIVETo compare the difference in the clinical efficacy on cervical spondylosis of vertebral artery type (CSA) treated with thermosensitive moxibustion at different dosages.

METHODSSixty cases of CSA were randomized into a saturated moxa dosage group and a regular moxa dosage group, 30 cases in each one. The thermosensitive moxibustion was adopted in the two groups. The mild suspended moxibustion was applied at two acupoints with the strongest thermosensitization. In the saturated moxa dosage group, the moxibustion time was determined by the disappearance of thermosensitization. In the regular moxa dosage group, 15 min was required on each acupoint. The treatment was given twice a day for first 4 days in the two groups. Since the 5th day, the treatment was given once a day, continuously for 10 times, and totally 14 days were required. The score of symptoms and function and clinical efficacy were compared between the two groups before and after treatment as well as 6-month follow-up after treatment.

RESULTSThe curative and effective rate was 56.7% (17/30) after treatment and 60.0% (18/30) in 6-month follow-up after treatment in the saturated moxa dosage group, which were superior to 26.7% (8/30) and 30.0% (9/30) in the regular moxa dosage group respectively (P < 0.01, P < 0.05). The scores of clinical symptoms and function after treatment and in follow-up were improved apparently as compared with those before treatment in both groups (all P < 0.01). The scores of clinical symptoms and function after treatment and in follow-up in the saturated moxa dosage group were increased much more apparently than those in the regular moxa dosage group (after treatment: 22.32 +/- 4.64 vs 17.43 +/- 3.21; in follow-up: 23.01 +/- 4.76 vs 18.32 +/- 2.13, both P < 0.01).

CONCLUSIONThe thermosensitization moxibustion of saturated dosage achieves the superior short-term and long-term efficacies in the treatment of CSA as compared with the regular moxibustion dosage.

OBJECTIVETo investigate the applications of percutaneous screw fixation for the treatment of pelvic fractures and its related surgical considerations.

METHODSFrom June 2010 to June 2012,19 patients with pelvic fractures were treated with percutaneous hollow screws. There were 13 males and 6 females, with an average age of 41 years (ranged from 22 to 58 years). Fractures were caused by traffic accidents in 11 cases, by falling down from high place in 8 cases. Based on the Tile classification, there were 15 cases of Tile C type and 4 case of Tile B type. The indexes such as screw inserting time, intraoperative blood loss, complications, functional recovery and reduction conditions were observed. Fixation methods included sacroiliac screws, cannulated screw fixation of the pubic ramus and cannulated screw fixation of the pubic symphysis separation.

RESULTSAnatomical reduction achieved in 7 cases, satisfactory reduction 11 cases, and unsatisfactory reduction 1 case. Union time of fracture union ranged from 8 to 12 weeks (mean 10 weeks). Wound infection,ununion of fracture and nerve injuries were not found. According to the Majeed standards, 12 patients obtained an excellent results, 6 good and 1 fair.

CONCLUSIONPercutaneous screw fixation for the treatment of pelvic fractures under fluoroscopy has several advantages such as less trauma, less blood loss, fewer rates of complications, reliable fixation and no blood transfusion, which can reconstruct the stability of the pelvic ring, but it needs adequate preoperative preparation and high requirements for the surgeon.
