AIM: To present the epidemiology, cause of injury, ocular status and final visual acuity after management of severe ocular trauma required hospitalization during 7 years in a representative urban Chinese population.METHODS: A retrospective analysis of the hospital admission files of ocular trauma patients admitted to the Daping hospital from January 2000 to December 2006 was carried out.RESULTS: A total of 268 patients were open-globe injury and the remaining 294 patients were closed-globe types. The most common causes of ocular injuries were metal (29.4%), explosive (14.6%) and stone (13.9%). And the visual outcomes of most of eye injury patients in this study were poor; half of injured eyes ended with visual acuity worse than 0.1.CONCLUSION: Therapeutic methods to ocular trauma make a great progress in recent years, but the visual outcomes are poor.

Purpose: To explore the clinical value of 99mTc-MIBI imaging in differentiating malignancies from benign breast masses. Methods: 195 patients underwent the examination for 99m Tc-MIBI. Comparative diagnosis was done by postoperative pathology in all cases. Results: 69 of the 84 cases of breast cancer were preoperatively diagnosed by 99mTc-MIBI, the causes of false-negative results were small size of the mass and the higher degree of malignancy. 102 of the 111 patients with benign lesions were scintimammographically negative, the cause of false-positive results was large fibroadenomas with surplus blood supply. The sensitivity was 82. 1%, specificity was 92.0%, and the diagnostic accuracy was 89.2%. Conclusions: 99mTc-MIBI examination is an effective, simple and noninvasive diagnostic method for primary breast cancer.

Based on M9 culture medium,the concentration of ingredients of culture medium was optimized for the fermentation of pNSR32/BL21(DE3),the engineering bacterial with spider silk protein,and lactose as an inducer.The condition of optimum culture medium was obtained for the expression of the high molecular weight recombinant spider silk protein by using orthogonal and individual factor experimental design.The result was showed that the optimum culture medium was consisted of 0.3% glycerol,3% yeast,0.75% tryptone,0.05%(NH_4)_2SO_4 and a little inorganic salt_.It was confirmed that the optimum culture medium will benefit the growth of bacterial and expression of recombinant spider silk protein.The production level of propose protein will attain at 20% of the total proteins in the fermentation.

Objective To evaluate the efficacy and safety of repeated endoscopic sclerotherapy injection(ESI) and endoscopic variceal ligation(EVL) in eradication of esophageal varices among patients who survive an episode of first variceal hemorrhage with a high risk of rehaemorrhagia and death. Methods The correlated literatures were identified from Medline,Embsae,the Library Cochrance,PubMed and CNKI.RevMan 4.2 Software provided by the Library Cochrance was used for data analysis. Results A total of 4 randomized controlled trials were included.It was demonstrated that there was no significant difference in the esophageal varices eradication rate between repeated ESI and EVL(OR=0.75,95%CI: 0.48-1.15;P=0.19).However,the rehaemorrhagia rate of EVL after emergency hemostasis was significantly lower than that of ESI(OR=2.19,95%CI:1.44-3.31;P=0.000 2).Meanwhile,there was no significant difference in mortality between ESI and EVL(OR=1.34,95%CI:0.82-2.17;P=0.24).Little publication bias was found with funnel plot analysis. Conclusion EVL outperforms ESL in prevention of rehaemorrhagia in treatment of esophageal varices,while does no better than ESL in eradication of esophageal varices and mortality.

Objective To report a retroperitoneal laparoscopic surgery for ureteropelvic junction obstruction (UPJO) by double renal veins.Methods A 28-year-old male patient with left low back pain for 6 months was diagnosed as left hydronephrosis and UPJO.A ureteral stent had been placed 3 months before and failed to improve hydronephrosis,so the ureteral stent was pulled out.CT scan showed that left UPJ went through the two renal veins,suggesting UPJO.Nephrogram showed that left GFR and right GFR were 35 ml/min and 34 ml/min,respectively.These results indicated mechanical obstruction of left upper urinary tract.The patient underwent retroperitoneal laparoscopic Anderson-Hynes dismembered pyeloplasty.Results The surgical procedure was successful.Two left renal veins were found,and the ventral one was in front of ureter,compressing the ureter.An aberrant renal artery went into left kidney with the ureter.0.5 cm stenosis of ureteropelvic junction was excised,and pyeloplasty was performed.A ureteral stent was placed into the ureter,then the pelvis and the ureter were sew up in front of the ventral renal vein.The surgical time was 240 min,and blood loss was 50 ml.Postoperative hospital stay time was 4 d.During 4 months' follow up,hydronephrosis was attenuated significantly.Conclusion Retroperitoneal laparoscopic surgery for UPJO with aberrant two renal vein might be a minimally-invasive and effective procedure.

Objective To analyze CT manifestations of inguinal canal lipomas (ICLS).Methods CT datas of 104 pa tients with ICLS was retrospectively analyzed.And the imaging features were observed by MPR.Results The main CT manifestations of the ICLS were fat density in the inguinal canal and were unconnected with the abdominal fat.Among the 104 ICLSpatients,male (90/104,86.54％) was more than famale(14/104,13.46％;x2=55.538,P＜0.001).Thele sions were located at bilateral sides in 8 cases,left side in 66 cases and right side in 30 cases.The lesions in left side were more than those in right side (x2 13.500,P＜0.001).The mean maximum cross-sectional area of ICLS was (3.89 ± 2.12)cm2.There was no statistically significant difference between male and famale in maximum cross-sectional area (t=1.038,P=0.302).Conclusion In ICLS patients,male is more than famale.And more lesions are located at the left side.The CT manifestations of ICLS have certain characteristics,and MPR images are helpful in diagnosing ICLS.

0.05).In the patients with 4G/4G polymorphism of PAI1 gene,the GMP-140,vWF,FⅦa,D-D and PAI-1 levels in plasma were significantly increased at immediate postoperative period(P0.05).In the patients with 4G/5G and 5G/5G genotypes,all indexes mentioned above were significantly increased at immediate postoperative period(P0.05).In the patients with 4G/4G genotype,the PAI-1 level in plasma was significantly higher than those in the patients with 4G/5G and 5G/5G genotypes 24 h after PCI(P

Acupuncture clinical trials are designed to provide reliable evidence of clinical efficacy, and SCI papers is one of the high-quality clinical efficacy of acupuncture research. To analyze these papers published in high impact factor journals on acupuncture clinical trials, we can study clinical trials from design to implementation, the efficacy of prevention and cure, combined with international standard practices to evaluate the effectiveness and safety of acupuncture. That is the core of acupuncture clinical trials, as well as a prerequisite for outstanding academic output. A scientific and complete acupuncture clinical trial should be topically novel, designed innovative, logically clear, linguistically refining, and the most important point lies in a great discovery and solving the pragmatic problem. All of these are critical points of papers to be published in high impact factor journal, and directly affect international evaluation and promotion of acupuncture.
