Objective To investigate the effect of proteasome inhibitor MG132 on the proliferation of human lens epithelial cells SRA01/04. Methods The SRA01/04 cells were treated with MG132 by different concentrations (0, 0. 1, 0. 5, 1. 0, 2. 5, 5.0, 10. 0μmol/L) for 36 hours. The cell viability in all groups was determined using methylthiazoltetrazolium (MTT) test. The effect of MG132 on the apoptosis and regulation of cell cycle about SRA01/04 cells were detected by flow cytometry (FCM). The SRA01/04 cells treated with MG132 were observed after Annexin V/FITC-PI staining by fluorescence microscope. Results The inhibitory effect of MG132 on SRA01/04 cells proliferation was enhanced with the increase of MG132 concentration. The 50% inhibiting concentration ( IC50 ) of MG132 was 2. 50μmol/L after SRA01/04 cells were treated with MG132 for 36 hours. The apoptosis index of the cells treated by MG132 at 2. 5μmol/L and 5 μmol/L for 36 hours was 6. 55 ± 0. 35% and 13.75 ± 3.18%, and 0. 75 ± 0. 21% for 5.0μmol/L for 36 hours in control group. After cells were treated with MG132 for 48h, the percentages of cells at G0/G1 phase were (42. 57 ± 0. 64) %, (73.42 ± 3.10) %, ( 80. 95 ± 3.83 ) % 0, 2. 5,5.0 μmol/Lgroups respectively, and those at S phase were (49. 44±1.36)%, ( 17. 40 ± 1.50)%, ( 19. 57 ± 1.29)%.Annexin V/FITC-PI staining was used, and MG132 was found to result to apoptosis. Conclusions MG132 could inhibit the proliferation of SRA01/04 cells by the effect of inducing apoptosis and regulation of cell cycle. The proteasome inhibitor-might play a key role in the prevention of posterior capsular opacification.

Objective To study the effect of predictive nursing combined with 317 nursing-nurse's education assistant on the bowel preparation of elderly patients.Methods The elderly patients who was hospitalized or physically examined between March and December 2017 were divided into two groups with their wills:60 cases in the observation group and 58 cases in the control group.In the former group, the education with the predictive nursing and the 317 nursing-nurse's education assistant by primary nurses was conducted and in the latter,the traditional oral and paper method was used for the bowel preparation. Results The quality of bowel preparation in the observation group was significantly higher than that in the control group. The complication rate in the observation group was significantly lower than that in the control group (P<0.05). Conclusion The predictive nursing combined with the 317 nursing-nurse's education assistant can improve the bowel preparation quality and reduce the complication rate in the elderly patients.

Objective: To explore the effects of multidisciplinary team based nursing intervention on nutritional status, muscle strength, physical function and daily living ability of super-aged patients with sarcopenia. Methods: A total of 29 super-aged patients with sarcopenia from July to November in 2017 in Department of Geriatric, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School were selected as the observation group with multidisciplinary team intervention. And 29 super-aged patients with sarcopenia from February to June 2017 were selected as the control group with routine management. Nutritional indicators, muscle strength, physical activity function and daily living ability scores were compared between the two groups at 1 and 6 months after intervention. Results: After 1 month of intervention, hemoglobin and serum albumin was (118.79±11.47), (35.86±5.73) g/Lin the observation group and (112.27±11.69), (31.35±5.48) g/L in the control group, the difference between the two groups was statistically significant (t value was 2.09, 2.98, P<0.05 or 0.01). After 6 months of intervention, hemoglobin, serum albumin, muscle strength, physical activity function and daily living ability was (124.66±13.52) g/L, (38.47±6.02) g/L, (23.75±3.61) g, (9.18±1.85) points, (86.19±14.36) points in the observation group, and (112.03±11.89) g/L, (31.01±5.91) g/L, (19.15±3.19) g, (6.14±1.69) points, (64.12±15.83) points in the control group, the difference between the two groups was statistically significant (t value was 3.68-6.37, all P<0.01). Conclusions Nursing intervention based on multidisciplinary team can improve the nutritional status, muscle strength,physical function and quality of life of super-aged patients with sarcopenia.

Objective To assess the tear film stability and morphological characteristics of the tarsal gland in myopic children.Methods In this prospective descriptive study,myopic children who performed refractive examinations in the Pediatric Ophthalmology & Refraction Clinic,Jinan Mingshui Eye Hospital from November 2021 to November 2022 were in-cluded.An Ocular Surface Disease Index(OSDI)questionnaire survey was carried out;tear meniscus height(TMH),non-invasive first breakup time(NIf-BUT)and images of the tarsal glands were obtained by OCULUS Keratograph 5M compre-hensive ocular surface analyzer.In addition,the atrophy and tortuosity of tarsal glands were scored to analyze the tear film stability and clinical characteristics of tarsal glands in myopic children.Results A total of 48 myopic children(91 eyes)aged from 7 to 16(10.25±2.23)years were recruited,including 27 males(56.25％)and 21 females(43.75％).The aver-age TMH was(0.19±0.04)mm(95％CI:0.18-0.19)and the average NIf-BUT was(5.40±2.62)s(95％CI:4.90-5.94);the TMH was positively correlated with NIf-BUT(r=0.223,P=0.034).The tarsal gland atrophy score was 1(0,1).The tortuosity score of the upper and lower tarsal gland was 0(0,1)and 0(0,0),respectively,with a statistically significant difference(Z=3.692,P＜0.001).In all subjects,49 eyes(53.85％)had tarsal gland atrophy,and 37 eyes(40.66％)had tarsal gland tortuosity.There were significant differences in TMH and NIf-BUT between children aged＜12 years and children aged &ge;12 years(both P＜0.05).There was a significant difference in TMH between children with an OSDI score＜13 and children with an OSDI score &ge; 13(t=2.305,P=0.026).There was a significant difference in NIf-BUT between mild and moderate myopia children(t=2.300,P=0.024);the spherical equivalent was positively correlated with NIf-BUT(r=0.283,P=0.023).Conclusion Children with mild to moderate myopia show low tear film stability and a certain proportion of abnormal morphology in tarsal glands.In addition to the refractive status of children,attention should also be paid to ocular surface health in the refraction clinic.
