Objective To determine the anatomical and visual outcome of indocyanine-green (ICG)-assisted internal limiting membrane (ILM) peeling for idiopathic macular holes. Methods Thirty-one eyes of 31 patients with 3- (14 eyes, 45.2%) and 4-staged (17 eyes, 54.8%) primary idiopathic macular holes were analyzed. All the patients underwent the subtotal pars plana vitrectomy with removal of the posterior vitreous. ICG solution with the concentration of 1.25 mg/ml was injected into vitreous cavity. The ILM was stained and removed in a circular fashion of 2 to 3 disc-diameter from the edge of the hole. At the end of the surgery, 14% C 3F 8 mixed gas was used and the patients were required to maintain a prostrate posture for two weeks postoperatively. The mean follow-up duration was 9.1 months. Results The preoperative median visual acuity was 20/200. In the final follow-up, 28 eyes (90.3%) had anatomical restoration of the macular holes, 21 eyes had improvement of two lines or more of visual acuity. There was no direct complication or toxicity related to ICG-assisted ILM peeling except one patient with retinal detachment caused by peripheral retinal hole. Conclusion ICG-assisted retinal ILM removal appears beneficial and safe for primary idiopathic 3 and 4-staged macular holes.

Objective: To investigate the relationship between dietary -related behaviors of college students and their health , so as to provide the evidence for the health education for college students .Methods:A question-naire survey was conducted among 2105 college students from Xi′an Jiaotong University with stratified cluster ran-dom sampling .Results:In this survey , college students generally had unhealthy dietary behaviors , cognitive bia-ses of self-images and blind unhealthy weight -losing phenomenon as well .And there was a difference of dieting behaviors between college students of different sex and those of different body mass index .Conclusions:Unhealth-y dietary behaviors of college students were one of the main reasons leading to their abnormal BMI .Hence , it was necessary to improve health ethics education and dietary health guidance for college students , so as to introduce them to consciously assume their own health responsibilities and manage their health .

Aim To investigate the preventive effects of misoprostol on osteoporosis in aged ovariectomized(OVX)rats.Methods Female,10-month-old SD rats were ovariectomized(OVX)and,2 months later,were treated with misoprostol or controls for 2 months.The static and dynamic parameters in trabecular bone of the forth lumbar vertebrae(LV4)were examined with histomorphometrical analyses;the fifth lumbar vertebrae(LV5)was used to perform the compression test.Results Compared with the data from the sham-operated rats,the percent trabecular area and elastic modulus significantly decreased in OVX rats.Correspondingly,the bone break load and break stress decreased of post OVX was compared with those of sham-operated rats.Misoprostol increased the percent trabecular area by 21.6% compared with OVX rats,but it couldn't meet the statistical significance.Misoprostol enhanced the break load and elastic modulus compared with OVX rats.Conclusion Misoprostol can improve biomechanics of bone in ovariectomized osteoporosis rats.

Objective To analyse the results of Zephir semiconstrained or Window dynamic cervical plates with autogenous cortical bone graft in treating the cervical spondylotic myelophathy(CSM). Methods A retrospective review was performed with 43 patients who underwent anterior cervical discectomy, autogenous cortical bone graft with endplate retaining, fixation with Zephir or Window cervical plates. Follow-up period ranged from 0.5 to 4.0 years (in average of 22 months). The clinical effect, the fusion rate, the intervertebral height and the degeneration of adjacent levels were observed. Results The JOA score after operation was significant higher than that before operation (P

Objective To compare the efficacy and safety of ivermectin with metronidazole in patients with intestinal acariasis.Methods 24 patients with typical intestinal acariasis were selected and divided into two groups,each group had 12 members.Double-blind,randomized clinical trial of ivermectin versus metronidazole was assigned.Results 24 patients completed 3 courses.The total cure rate of ivermectin and metronidazole were 100%(12/12) and 25%(3/12),respectively.There was statistical difference between the two groups(P

The survey of the soluble IL-2 receptor (sIL-2R) level in the sera and the membrane IL-2 receptor (mIL-2R) expression on the peripheral blood mononuclear cells (PBMCs) from 47 cases of late schistosomiasis japonica was reported. The measurement for sIL-2R was done with the double antibody sandwich ELISA. Indirect immunflurescence was performed in the measurement for mIL-2R. The levels of sIL-2R in sera from 47 patients with late schistoso-miasis was found to be higher than that in control (P

AIM:To establish a HPLC fingerprint of Stellera chamaejasme L. from Inner Mongolia Region. METHODS: The RP-HPLC method was used with Akzonobel Kromasil C_ 18 (250 mm?4.6 mm, 5 ?m) the acetonitrile-0.5% phosphoric acid (gradient elution) was used as mobile phase, analytic time was 60 min, and detective wavelength was at 297 nm, the column temperature of 15℃ were adopted. RESULTS: The HPLC fingerprint of Stellera chamaejasme L. set up showed that 14 peaks were co-possessing in different sources. The results of method validation met technical standard of fingerprint, the similarities of Stellera chamaejasme L. were 0.9 to 1.0. CONCLUSION: The method is stable and reliable with a good reproducibility and provides a reference standard for the quality control of Stellera chamaejasme L. from Inner Mongolia Region.

Objective To discuss the outcomes of the clinically insignificant residual fragments after minimally invasive percutaneous nephrolithotomy. Methods 75 patients (11％) with CIRF among 655 who underwent initial MPCNL from January 2008 to December 2010 were diagnosed by CT scan.Clinical data of 68 patients (39 male and 29 female) were analyzed retrospectively.Previous open surgery hadbeen performed in 13 and ESWL in 20 cases.The median residual fragment size was 1.8 mm.The anatomical distribution of CIRF was 9 at upper pole,14 at middle,34 at lower,9 at renal ureteropelvic junction and 2 at upper and lower pole.Stone analysis showed 40 cases of calcium oxalate calculi,15 of calcium oxalate calculi mixed with carbonate calculi,2 calcium oxalate calculi mixed with uric acid,3 calcium oxalate calculi mixed with struuvite stone,3 struuvite stone,2 uric acid stone and 3 carbonate apatite mixed with struvite stone.Mean follow up was 23 months (12-36).Follow-up consisted of physical examination,serum routine,urine routine and CT imaging. Results 14(21％) patients (3 upper pole,1 middle pole,4 lower pole and 6 ureteropelvic junction) had symptomatic episodes,including 9 hematuria,2 renal colic pain,5 lower urinary tract symptoms,12 with size of CIRF ＞ 4 rmm.8 patients required surgical procedures.5 patients (1 middle,2 upper pole and 2 renal pelvis) underwent ESWL.3 patients with ureteral CIRF were performed ureteroscopic lithotripsy.The CIRF were clear after surgeries.4 paticnts with CIRF ＞ 4 mm did not have symptoms.These patients were recommended to conservational treatments.2 patients with ureteral CIRF had renal colic pains.The stones were excluded after spasmolytic analgesic treatments.27％ (3/11)CIRF located in upper pole had symptom,compared with 4％ (1/14) in middle pole,11％ (4/36) in lower pole and 67％ (6/9) in ureteropelvic junction. Conclusions CIRF can be located variously in the kidney and ureter.Most CIRF are calcium oxalate calculi and locate in the lower pole.Patients with the history of previous open surgery or SWL are more likely to get CIRF.Medium-term follow-up of CIRF revealed that CIRF located in the renal ureteropelvis junction are more likely to have clinical symptoms.
