Genetic factors play an important role in the occurrence and development of AMD. ln recent years, the studies found that complement factor H ( CFH) gene has obvious correlation with the incidence of AMD. ln this article, we reviewed the researches on the CFH in AMD.

Abstract?AIM: To obtain the prevalence and risk factors of symptomatic dry eye disease ( SDED ) among college students in China.?METHODS:Population-based cross-sectional study. Students in Medical School of Lanzhou University were approached. A questionnaire was used to evaluate the prevalence of SDED and its risk factors. The diagnosis of SDED was based on reported symptoms and was established if the participants reported “often” or “all the time” once or more for 6-item questionnaire. Positive tests included a tear-film breakup time ( TBUT)≤10s and a fluorescein staining score ( FSS ) ≥1. Demographic information and possible factors that may contribute to SDED were analyzed in a step-wise multivariate logistic regression modelto assess risk factors of SDED.? RESULTS: There were 1139 participants ( 84. 37%response rate ) have completed the questionnaire, 475 males and 664 females aged 16-26y. The prevalence of SDED was 18. 70% [95% confidence interval ( CI)= 16. 59-20. 81]. A TBUT of ≤10s and a FSS≥1 were noted in 47. 67%(95% CI=44. 95-50. 57) and 13. 97%(95% CI=11. 95-15. 99) for all participants, respectively. The multivariate regression analysis revealed the following risk factors:daily reading time of≥4h(OR=1. 58,95% CI=1. 15-2. 18), daily computer use of≥4h ( OR= 1. 52, 95% CI= 1. 02-2. 25), and constant eyeglasses wearing (OR=1. 54,95%CI=1. 08-2. 13). The female gender, refractive surgery and contact lens ( CLs) wearing were not risk factors for SDED in this analysis.? CONCLUSION: The prevalence for SDED is high in Chinese college students. The risk factors include daily reading time of≥4h, daily computer use of≥4h and constant eyeglasses wearing.

Objective To evaluate the efficacy and safety of clip traction in endoscopic submucosal dissection (ESD) for heterotopic pancreas in stomach.Methods Data of 62 patients with pathologically confirmed heterotopic pancreas treated by ESD between May 2013 and February 2016 were retrospectively studied in Department of Gastroenterology of Xinqiao Hospital,whose lesions were single and origins were submucosal.Thirty-six cases underwent ESD with clip traction (clip group,n=36),and 26 cases underwent ESD without clip traction (non-clip group,n =26).The procedure time,visualization of the submucosal during dissection,complications and the result of follow-up were evaluated between the two groups.Results ESD was successful in all cases.The procedure time was significantly shorter in the clip group than in the non-clip group (19.35±10.34 min VS 27.02± 14.27 min,t'=2.333,P=0.023),and good visualization was obtained by applying clip traction.The rate of bleeding in the clip group was 55.6％ (20/36),and that in the non-clip group was 61.5％ (16/26).There was no significant difference between the two groups(x2 =0.222,P =0.638).Moreover,perforation did not occur in the clip group,but occurred in one patient in the non-clip group (3.8％,1/26).There was no significant difference between the two groups (P =0.419).All patients were followed up,there was no recurrence.Conclusion ESD is effective and safe for heterotopic pancreas in stomach.Clip traction can shorten the operation time and reduce complications of ESD.

OBJECTIVE:To strengthen the supervision of clinical antibiotics use through establishing electronic consultation system. METHODS:Based on hospital information system(HIS)and antibiotic management system,consultation system for anti-biotics of special use(ASU)was established,and the effects of the system after used(Jan. 2014)were also evaluated. RESULTS:Real-time consultation of ASU medical orders and related consultation results inquiry and statistics could be achieved through de-signing ASU consultation application form,establishing consultation experts and confirming their working content,adding statistics function,etc. The consultation have been finished 8275 times from 2014 to 2015. The inspection rate for pathogenic microbes in ASU patients rose from 78.68% in 2013 to 83.90% in 2015. CONCLUSIONS:The establishment and application of ASU consulta-tion system can improve consultation efficiency and quality,so as to promote rational use of antibiotics in the clinic.

Objective:To observe the efficacy and safety of intrapleural injection with urokinase ( UK) in the treatment of tubercu-lous pyothorax. Methods:Totally 120 patients with tuberculous pyothorax were randomly divided into two groups. The vomicae in the control group were rinsed with 5% sodium bicarbonate, and those in the observation group were treated with UK. The total effective rate, symptom relief time, closure time of vomicae, pleural thickness changes and adverse reactions were observed in the two groups. Results:The total effective rate of the control group and the observation group respectively was 81. 7% and 98. 3%, which showed sta-tistically significant difference (P<0. 01). The symptom remission time and the pus cavity closure time of the observation group were shorter than those of the control group (P<0. 05). The pleural thickness of the observation group was thinner than that of the control group at the end of the treatment (P<0. 05). The incidence of adverse drug reactions in the observation group was significantly higher than that in the control group (P<0. 01). Conclusion:The curative effect of UK in the treatment of tuberculous pyothorax is better than that of sodium bicarbonate, however, it is necessary to pay attention to monitoring such adverse reactions as bleeding, low heat and the others.

To investigate the prognostic effects of integrated traditional Chinese and Western medicine therapy without antibiotics in treatment of patients with severe acute pancreatitis (SAP).

OBJECTIVETo investigate results of total knee arthroplasty using the long-stem tibial component combined with metallic wedge of knee prosthesis for the treatment of proximal defects.

METHODSFrom January 2011 to May 2013, 10 patients (11 knees) were treated with total knee arthroplasties using the long-stem tibial component with metallic tibial wedge of knee prosthesis. All the patients were female and the average age was 67 years old (ranged, 60 to 77 years old). All the patients were osteoarthritis. All the patients were classified as T2A style. The patients were evaluated according to knee score system (KSS).

RESULTSAll the patients were followed up for 12 months on average (ranged 3 to 29 months). The clinical outcome was assessed using KSS score, including knee pain score, knee stability score, knee range of motion score and knee walking score, knee stairs score. There were significantly differences at 6 weeks, 3 months, 6 months and 12 months between pre-and postoperative KSS score.

CONCLUSIONThe mechanical stability of tibial fixation in primary TKA is significantly increased by using the long-stem tibial component with metallic wedge of knee prosthesis, even in the presence of poor proximal bone.

OBJECTIVETo analyse the video-oculographic findings of positional tests and evaluate the efficacy of canalith repositioning procedure (CRP) in patients with paroxysmal positional vertigo ( BPPV) of the anterior semicircular canal (ASC).

METHODSA retrospective study of 31 patients with ASC BPPV. Then the CRP was performed.

RESULTSTwenty-two individuals (70.97%) presented a unilateral positional nystagmus during the Dix-Hallpike test, in 17 individuals had torsional nystagmus component, 5 individuals only had pure positional down beat nystagmus. Nine patients presented bilateral positional nystagmus, 7 individuals had torsional component positional nystagmus, in 2 patients the direction of the torsional component were the same during right and left Dix-Hallpike test, in 4 patients the torsional component were concurrent with positional down beat nystagmus but the direction could not be ascertained clinically, in 2 patients had pure positional down beat nystagmus. Nineteen patients (61.29%) had unilateral lesion, 11 patients had the left ASC BPPV, 8 patients had right ASC BPPV. Eleven patients had with both ASC and PSC BPPV in the ipsilateral. Twenty-one patients (67.74%) were cured, 29 patients (93.55%) were improved, 2 (6.45%) patients were inefficacy. CRP effectively resolved the nystagmus and vertigo in 14 patients (45.16%) when applied only once, The average number of CRP was 1.7 times, there were 5 patients recurrence during the follow-up.

CONCLUSIONSASC BPPV was not a common condition. The torsional nystagmus component of ASC BPPV might be weak during the Dix-Hallpike test. The positional nystagmus of ASC BPPV was triggered bilaterally. Based on these findings, CRP could be one of the most effective treatment methods for ASC BPPV.

OBJECTIVETo investigate the clinical effect of penile augmentation with superficial fascia retrocession.

METHODSThe first annular incision line was designed, reserving the inner plate 0.5 -0.8 cm. The second annular incision line was determined, according to the length of penile erection. The skin tissue between the double loops was stripped, reserving the superficial fascia and the superficial dorsal veins. Before the closure of two annual incision with no tension, the superficial fascia tissue was pushed proximally and fixed sectionally to augment penis.

RESULTSFrom Jun 2009 to Jun 2011, 60 patients with redundant prepuce or phimosis were treated with this method. During 3 to 12 months follow-up, the postoperative penile perimeter increased significantly. The glans were exposed and the prepuce looked smooth. The function of the penis maintained undamaged.

CONCLUSIONSThe penile augmentation with superficial fascia retrocession can make full use of autologous tissue to augment penis, meanwhile, redundant prepuce can be resected. It is very practical for clinical application.
