Objective To observe the cervical regeneration outcome after different loop electrosurgical excision procedures(LEEP) for the management of cervical lesions.Methods A total of 209 patients with cervical lesions including cervical epithelial neoplasia,cervical HPV infection,cervical polyp and condyloma,and severe cervicitis were performed LEEP in our hospital.The types of LEEP included shallow ring excision,deep ring excision,LEEP conization,and that similar to cold-knife conization.The width and depth of removed cervical tissues were recorded,and the cervical regeneration was observed during the follow-up. Results Among the 209 cases,179(85.6%) were satisfactory cervical regeneration,24(11.5%) were little satisfactory cervical regeneration,and 6(2.9%) were unsatisfactory cervical regeneration.Shallow ring excision,deep ring excision and cone excision had higher satisfactory situation.Extroversion of cervical columnar epithelium was observed in 15 cases(7.2%) in little satisfactory cervical regeneration.Severe extroversion of cervical columnar epithelium of 3 cases occurred in unsatisfactory cervical regeneration.Besides,there were 2 case of cervical shortening and 1 case of severe erythema in unsatisfactory cervical regenerations. Conclusion Although having such complications as extroversion of cervical columnar epithelium,cervical shortening and erythema,LEEP performs a high satisfactory cervical regeneration after management of cervical lesions.It is in great need to analyze the condition of different patients in managing cervical lesions by LEEP.

To evaluate the efficacy and safety of limbal relaxing incision ( LRl) for correcting corneal astigmatism during implantable collamer lens ( lCL) surgery.METHODS:A total of 185 eyes of 105 patients with high myopia and corneal keratometric astigmatism were included in the study. lCL surgery with concomitant relaxing incision was performed in 105 eyes of 60 patients in LRls group ( Group A) . Eighty eyes of 45 patients only underwent lCL surgery were in control group ( Group B) . All patients undergone ophthalmic examination that included uncorrected visual acuity ( UCVA ) , best -corrected visual acuity ( BCVA ) , Pentacam analysis system to observe the changes of corneal astigmatism before and 1wk, 1 and 3mo after surgery.RESULTS: Respectively comparing UCVA between two groups in 1 and 3mo postoperatively, the P values were considered statistically significant ( P < 0. 05 ). But, respectively comparing BCVA between two groups in 1wk, 1 and 3mo postoperatively, the P values were considered no statistically significant ( P > 0. 05 ). Preoperative corneal astigmatism was 1. 52 ± 0. 55D in group A and 1. 48 ± 0. 57D in group B, there was no statistically significant difference (P>0. 05). One week postoperatively, the astigmatism was 0. 55 ± 0. 41D in group A and 1. 20 ± 0. 48D in group B. One month postoperatively, the astigmatism was 0. 60 ± 0. 38D in group A and 0. 93 ± 0. 47D. Three months postoperatively, the astigmatism was 0. 51 ± 0. 32D in group A and 0. 96 ± 0. 40D in group B. The difference between the two groups were statistically significant ( P<0. 05 ). The difference value of corned astigmatism before surgery and 1wk, 1 and 3mo after surgery had statistical significance ( P<0. 05). ln LRls group, at preoperative and postoperative time points, the average corneal astigmatism changes were also considered statistically significant difference (P<0. 05). CONCLUSlON: LRls performed during lCL surgery appeared to be an effective and safer procedure to reduce pre-existing corneal astigmatism and improve UCVA as well as the visual quality.

Objective To investigate the diagnostic value and feasibility of PTC diagnosis on pancreaticobiliary maljunction (IBM), and to summarize the PTC radiological characteristics of PBM. Methods Clinical findings and cholangiopancreatographic results were analyzed retrospectively for a group of consecutive 363 patients with obstructive jaundice receiving the PTCD therapy. Meanwhile the standard selected for cases and diagnostic conditions were established. The length and diameter of pancreaticobiliary common duct, the diameter of pancreatic duct and common bile duct and the confluence angle were measured respectively. The t test and rank sum test were used to analyze the result statistically. Results Thirty-eight cases were radiologicaUy diagnosed as PBM owing to the reference standard and the detection rate was 10.5% (38/363). The length of common duct was (12.6±7.9)mm. The significant difference existed between it and normal value (6ram) (t=5.15 , P <0.05). The site of duodenal papilla had influence on the length of common duct. The diameter of common bile duct, pancreatic duct and common duct near the confluence are (3.7±1.9 ) mm, (2.4±1.3) mm, (3.3±1.4 ) mm, respectively. There was no statistical difference between them and the normal value (t=1.79,2.85,5.72, P>0.05). Fifteen patients' duodenal papilla located the middle of descending duodenum. The length of common duct was (10.6±9.1)mm , the confluence angle was 51.1°±28.0°, the number of the duodenal papilla locating in the inferior 1/3 of descending duodenum, juncture , horizontal part of duodenum was 10, 8,5, respectively. The length of common duet were (9.9±3.7), ( 18.6±8.9), ( 13.9±3.5 ) mm, respectively. The confluence angle were 54.0°±18.6°、48.7°±12.6°、74.4°±18.5°, respectively . The site of duodenal papilla had significant influence on the length of common duct(X2=14.51, P <0.05). Conclusion PTC is a safe, feasible, method to diagnose PBM, and it demonstrates the characteristic findings of PBM.

Objective To explore the application value of uric indicant monitoring on patients with impaired glucose tolerance. Methods 9 6 health examination people were selected who with glucose tolerance impairment diagnosis standard population in Jan to Feb 2015 in LaiZhou,There were no significant differences in age and sex composition between the two groups in 48 cases of experimental group and 48 cases in control group.There were no other diseases,and no drugs were taken to con-trol blood glucose.IGT patients in the experimental group using uric indican monitoring to establish personal diet guide, while the control group used normal health education guidance,the two groups respectively before experiment and at the end of detecting urinary indican,fasting blood glucose,2h glucose tolerance levels,and were compared.Results According to the findings of the two groups follow up and the experimental data collected during one year,at the end of the experiment the IGT patients in the experimental group levels of urinary indicant was (50.7±6.2 mg/L vs 78.5±7.9 mg/L),fasting blood glucose was (6.34±0.11 mmol/L vs 6.91±0.29 mmol/L),2h glucose tolerance was (7.81 ± 0.52 mmol/L vs 9.57 ± 1.13 mmol/L)which was lower than the control group.There was significant difference between two groups (t=2.0,2.6, 3.06,P<0.05).Compared with IGT in the experimental group at the end of the experiment,the level of uric indican was (50.7±6.2 mg/L vs 78.3±8.1 mg/L),fasting glucose was (6.34±0.11 mmol/L vs 6.78±0.19 mmol/L),2h glucose tol-erance was (7.81±0.52 mmol/L vs 9.33±0.93 mmol/L)was lower than before the start of the level (t=2.01,2.28, 2.83,P<0.05),and the difference was statistically significant.In terms of the outcome of the various stages of diabetes, IGT patients in the experimental group was significantly better than the control group (χ2=10.85,P<0.05),the difference was statistically significant.Conclusion Through the determination of uric indican to guide the glucose tolerance decrease in patients with a reasonable diet,is conducive to glucose tolerance in the patients with impaired on blood glucose control,can effectively reduce the glucose tolerance decrease (IGT)conversion to diabetes mellitus (DM),change to a positive direction.
