Objective: To investigate the factors associated with the patient's adherence to screening in the five years before the diagnosis of hepatocellular carcinoma (HCC) related to chronic hepatitis B ( CHB ), so as to provide reference for improving the screening rate. Methods: From June 2016 to April 2018, the patients with newly diagnosed HCC and a history of CHB for more than five years in Southwest Hospital in Chongqing were interviewed. The information about socio-demographic characteristics, health status, medical care and HCC screening in the past five years were collected. A multivariate logistic regression model was used to analyze the factors associated with adherence to screening. Results: Among 420 participants, 140 ( 33.33% ) adhered to HCC screening, 124 ( 29.53% ) had irregular/incomplete screening, while 156 ( 37.14% ) never had screening. The proportion of early-stage HCC at diagnosis was significantly higher in patients who adhered to screening ( 77.14% ) than that in patients who had irregular/incomplete screening (35.48%) or no screening ( 12.82% ) and the differences were statistically significant ( P<0.05 ). The multivariate analysis demonstrated that five factors were significantly associated with patient's adherence to screening, including education level of high school and above ( OR=2.346, 95%CI: 1.370-4.017), family history of HCC ( OR=2.795, 95%CI: 1.457-5.362 ), history of chronic diseases ( OR=3.860, 95%CI: 2.052-7.262), acceptance of antiviral therapy ( OR=17.816, 95%CI: 9.702-32.716 ) and specialized clinic visits ( OR=8.332, 95%CI: 1.588-43.710 ). Conclusions Adherence to screening is conducive to the early detection of HCC, but the screening rate is low in the patients with CHB. Education level, history of HCC, health status and medical status are significantly related to screening adherence.

AIM: To evaluate the effects of 23G vs 20G pars plana vitrectomy ( PPV ) combined with internal limiting membrane peeling, phacoemulsification and intraocular lens implantation for macular epiretinal membrane with cataract. ·METHODS: Totally 45 eyes of 45 patients with macular epiretinal membrane and cataract were enrolled in this retrospective non-randomized controlled clinical study. All eyes were treated with PPV combined with internal limiting membrane peeling, phacoemulsification and intraocular lens implantation. There were 20 eyes in 23G PPV group, and 25 eyes in 20G PPV group. The best corrected visual acuity ( BCVA ) , intraocular pressure (IOP), counting of corneal endothelial cells ( CEC) and central retinal thickness ( CRT ) were examined before surgery. BCVA results were converted to the logarithm of the minimum angle of resolution ( LogMAR ) visual acuity. All operations were performed by the same doctor. Operation time for vitrectomy and membrane peeling, average ultrasound energy ( AVE) and effective phacoemulsification time ( EPT ) were recorded. BCVA and CRT were observed postoperatively at 30d and 90d, counting of CEC was observed postoperatively at 90d. IOP was observed postoperatively at 1d and 7d. ·RESULTS:The mean operation time for vitrectomy were 12. 57± 1. 35min in 23G group and 17. 30 ± 1. 19min in 20G group. The difference was statistically significant ( t =-12. 488, P<0. 01). There were no statistical significances in operation time for membrane peeling, AVE and EPT between 23G and 20G groups ( t=-0. 68,-1. 186,-0. 737, P=0. 500, 0. 242,0. 465). On 1d after surgery, IOP in 23G group was lower than that in 20G group, the difference was statistically significant (t= -2. 345, P=0. 024). The BCVA and CRT of the two groups both improved after operations. There were no statistically significant differences between two groups in terms of IOP, BCVA, and CRT ( F = 0. 465, 1. 895, 0. 689; P = 0. 499, 0. 176, 0. 411). IOP, BCVA and CRT were significant statistical different in different time-point within each group ( F=291. 245, 103. 06, 665. 402, P<0. 01 ). Different surgical methods of 23G and 20G had interactive effects on IOP with different time points ( F = 13. 245, P<0. 01 ), but different surgeries had no interactive effects on BCVA and CRT with different time points (F=1. 212, 2. 293;P=0. 283, 0. 129). The counting CEC in 23G group was more than that in 20G group postoperatively at 90d, the difference was statistically significant (t=2. 049, P=0. 048). ·CONCLUSION: The 23G PPV combined with internal limiting membrane peeling, phacoemulsification, intraocular lens implantation for macular epiretinal membrane with cataract is effective. Compared with 20G PPV, 23G PPV has advantages in operation time for vitrectomy and counting CEC. But lower IOP is likely in 23G PPV on 1d after surgery

AIM: To explore the frequency of drug injection of alloxan diabetes on the established model of rabbit.METHODS: Thirty-six healthy rabbits, weighing 2-2.5kg, were randomly divided into one time drug injection group (group A, n=12), two times drug injection group (group B, n=12) and three times drug injection group (group C, n=12). Each rabbit was injected with a total amount of 150mg/kg of alloxan. Fasting blood glucose was measured. The success rate and death rate of each group were also calculated.RESULTS: The success rate of diabetic rabbit model in group B was higher than that in group A (P<0.01) and its death rate was lower than that of group A (P<0.01); the success rate of diabetic rabbit model in group C was highest and the death rate was the lowest in three groups(P<0.01). CONCLUSION: Multiple administration of alloxan can improve success rate in establishing diabetic rabbit model with decreased death rate and increased stability.

OBJECTIVETo explore the clinical effects of transforaminal endoscopic spine system in surgical revision of lumbar vertebrae.

METHODSFrom January 2012 to October 2013,14 patients who needed reoperations of lumbar vertebrae were treated using transforaminal endoscopic spine system (TESSYS). There were 8 males and 6 males, aged from 27 to 84 years old with an average of (50.4 ± 18.9) years. Visual analogue scale (VAS) and Japanese Orthopaedic Association Scores (JOA) were compared before and after surgical revision. Macnab standard was used to assess the clinical effect.

RESULTSAll the patients were followed up from 6 to 27 months with the mean of 18 months. Preoperative VAS score was 6.79 ± 1.31, and in a week,3 months and 6 months after operation were 2.50 ± 1.29, 2.21 ± 1.53, 1.64 ± 1.08, respectively, which were all much lower (P < 0.01) than preoperative score. Preoperative JOA score was 12.43 ± 1.95, and the above corresponding postoperative JOA scores were 21.50 ± 3.78, 21.93 ± 4.55, 23.36 ± 4.33, respectively, which were all much higher than preoperative score (P < 0.01). According to the modified Macnab criteria, 5 patients got an excellent results, 7 good, 1 fair and 1 poor. The nerve root injury of L5 occurred in 1 case during paracentesis and no other complications were found.

CONCLUSIONSelecting the appropriate indications using TESSYS in surgical revision of lumbar vertebrae can successfully avoid the operation scar, reduce the surgical complications and obtain satisfactory clinical outcomes.
