Objective To study the effect of double capsulorhexis combined with anterior vitrectomy in children with congenital cataract.Methods 42 (71 eyes) (age from 3 months to 14 years) underwent posterior continuous circular capsulorhexis (PCCC) and anterior vitrectomy after cataract extraction, and intraocularlens (IOL) were implanted in some eyes.The median follow-up time was 24 months.Results Among the 61 eyes of 37 patients who could do the visual examination,39 eye shada corrected visual acutiy of 0.5 or better, 16 eyes had a corrected visual acutiy of 0.3 or better;6 eyes had a corrected visual acuity of 0.3 or below.The postoperative complications included uveitis in 9 eyes,cornealede main 8 eyes,posterior capsular opacity(PCO) in 5 eyes.Some severe complications such as off centre IOL,cystoid macularedema and retinal detachment did not occur.Conclusion The double capsulorhexis combined with anterior vitrectomy and IOL implanted into eye should be a safe and effective method to prohibit after cataract in children with congenital cataract.

Objective To investigate the effect of 12 Fr catheter on the catheteration for the patients with prostatic hypertrophy after stroke. Methods One hundred and four sixteen patients with prostatic hypertrophy from urinary detention were divided into the control group (n=80) and the observation group (n=84) based on the odd and even numbers of admission date according to a digit random table. The control group received catheteration with a 14~20 Fr catheter, and the observation group did with a 12 Fr catheter. The two groups were compared in terms of pains, urethral injury and leakage of urine during intubation. Result The pain, urethral injury, leakage of urine in the observation group were all significantly lowered than those of the control group (all P<0.05). Conclusions 12 Fr catheter for catheteration for the patients with post-stroke prostatic hypertrophy can significantly reduce the degree of pain, the urethral injury and leakage of urine. Thus it is worthy of clinical application.

OBJECTIVE:To study sterility test after using Non-PVC bivalve soft-bag injection in PIVAS. METHODS:The test was divided into 3 groups according to the type of transfusion solution packaging and dispensing environment. Group 1 received Glucose solution using bivalve soft-bag,dispensed in PIVAS;group 2 received Glucose solution using bivalve soft-bag,dispensed in wards area;group 3 received Glucose solution using plastic bottle,dispensed in wards area. After puncturing 1,3,6,9 times (n=80),finished products placed in ward for 0,2,4,6 h(n=20),and then sterility test was conducted with membrane filtra-tion method stated in second part of Chinese Pharmacopoeia (2010 edition). Infusion contamination of 3 groups was analyzed at 9th puncture. RESULTS:The growth of bacteria was not found in group 1;the positive detection rate of group 2 and 3 were 2.5%and 3.8%(n=320). The total positive detection rates after puncturing 1,3,6,9 times were 0,0.4%,0.4%,7.5%(n=240);the positive detection rates of group 1 were all 0,those of group 2 were 0,1.25%,0,8.75%and those of group 3 were 0,0,1.25%, 13.75%(n=80). After 9 times of puncture,the positive detection rates of group 1 after placing 0,2,4,6 h were all 0,those of group 2 were 25%,5%,0,5%;those of group 3 were 5%,15%,5%,30%(n=20). CONCLUSIONS:The use of the Non-PVC bi-valve soft-bag injection in PIVAS can effectively prevent microbial contamination.

Diagnostics is one of the most important bridge courses for medical students from basic to clinical. Doctor-patient communication runs through the whole process of patient diagnosis and treatment. How to improve medical students' ability of doctor-patient communication? Our teaching team has carried out continuous reform and explored the scientific effective teaching mode. Recently, through the construction of "doctor-patient communication skills" quality online course, efforts have made to build an online and offline blended learning mode, which has gradually realize the integration with diagnostics teaching, and has achieved remarkable results. It also provides a scientific practical basis for the integration of doctor-patient communication and other clinical courses, which is worthy of promotion.

Objective To investigate the correlation between neutrophil-lymphocyte ratio (NLR) and disease activity of systemic lupus erythematosus (SLE),and the changes of NLR in different organ involvement of SLE patients.Methods A total of 155 SLE patients and 135 healthy controls from the Rheumatology Department of Xiangya Hospital were enrolled in this study from 2010 to 2018.Patients with SLE were divided into lupus nephritis group (LN group) and non-lupus nephritis group (non-LN group),serositis group and non-serositis group,according to whether they had kidney involvement or serositis.According to the SLE disease activity index 2000(SLEDAI-2000),the patients were divided into mild to moderate disease activity group (SLEDAI score ＜ 15) and severe disease activity group (SLEDAI score≥ 15).The NLR values of the above groups were compared.Spearman's correlation analysis was used to analyze the correlation between NLR and SLE patients' laboratory indexes.Multiple linear regression model was used to analyze the relationship between NLR and SLE disease activity.Receiver operating characteristic curve (ROC) was used to evaluate the value of NLR in SLE diagnosis and activity assessment.Results (1)The NLR value of SLE patients was significantly higher than that of healthy control group,and the difference was statistically significant (P ＜ 0.01).(2)The NLR value of SLE patients in the LN group was higher than that in the non-LN group,and the NLR value of SLE patients with serositis was higher than that in the group without serositis,with statistically significant differences (both P ＜ 0.05).(3)The NLR value of SLE patients in the severe disease activity group was higher than that in the mild and moderate disease activity group,and the difference was statistically significant (P ＜ 0.01).(4)NLR of SLE patients was positively correlated with CRP (rs=0.188,P=0.019),SLEDAI score (rs=0.264,P=0.001),and negatively correlated with total serum protein (rs=-0.250,P=0.002) and serum albumin (rs=-0.329,P ＜ 0.001),respectively.(5) Multiple linear regression showed that NLR was independently associated with SLE disease activity (B=0.351,95％CI 0.012-0.690,t=2.047,P=0.042).(6) According to ROC curve,the optimal cut-off value of NLR for SLE diagnosis was 2.17 (sensitivity 60.0％,specificity 83.1％,AUC=0.744),and the best cut-off value for predicting the activity of severe disease activity in SLE patients was 3.28 (sensitivity 58.5％,specificity 78.1％,AUC=0.700).Conclusion NLR is closely related to renal involvement,serositis and disease activity in SLE patients,which indicates that NLR,as a new inflammatory indicator,is of great significance for the assessment of SLE disease activity and organ involvement.
