AIM: To explore correlation,consistency and comfort between traditional tear film examination methods and Oculus Keratograph.METHODS: A retrospective study.Totally 101 cases (101 eyes) were diagnosed myopia and then accepted LASEK (laser epithelial keratomileusis).Non-invasive tear film break-up time(NIBUT),lower tear meniscus height(LTMH) were measured with Oculus Keratograph,fluorescein tear film break-up time(fl-BUT) and Schimer Ⅰ test (SⅠt) were performed on all cases.The correlations analysis between NIBUT and fl-BUT,LTMH and SⅠt were performed by Spearman rank correlation,consistency check between NIBUT and fl-BUT by Bland-Altman analysis.Visual analogue scale(VAS) was applied on evaluating the comfort of two kinds of examination methods.RESULTS: LTMH and SⅠt showed positive correlation (rs=0.346,P=0.001).NIBUT and fl-BUT showed positive correlation (rs=0.393,P=0.001),95% consistency limits range-9.62 to 14.18 in Bland-Altman Figure.There was significant difference between VAS of NIBUT and VAS of fl-BUT(z=-2.324,P=0.020).There was significant difference between VAS of LTMH and VAS of SⅠt (z=-8.845,P=0.001).CONCLUSION: Oculus Keratograph can objectively measure NIBUT and LTMH,and was more comfortable than traditional tear film examination methods.It can effectively assess tear film function before corneal refractive surgery.

AIM:To investigate the difference of non - invasive tearfilm break - up time (NIBUT) by Keratograph 5M beforeand after forced eye opening in healthy individuals.METHODS: Prospective case self - control study. Fortynormal volunteers (79 eyes ) were enrolled. Tear filmimages were captured, non-invasive first tear film breakuptime(NIBUTf ), non- invasive average tear film breakuptime (NIBUTav ) and dry eye level were measured byKeratograph 5M automatically before and after forced eyeopening in each subject. For the first time, we checkedthe left eye after the right eye, and the second timechecked the right eye after the left eye.RESULTS: The average of NIBUTf and NIBUTav were9 18士5. 52s, 11. 74 士5. 59s respectively and percentage ofevery level of dry eye were 43% , 37% , 20% respectivelybefore forced eye opening. The average of NIBUTf andNIBUTav were 8. 91士5. 54s, 11. 76士5. 58s and percentage ofdry eye at different levels were 35% , 48% , 16%respectively after forced eye opening. There was nosignificant difference on NIBUT and dry eye level byOculus keratograph 5M in normal subjects (t = 0. 37, P =0 72; t = -0. 038, P = 0. 97; Z = -0. 42, P = 0. 68).CONCLUSION: There is no influence on NIBUT and dryeye level by detected Keratograph 5M before and afterforced eye opening in healthy subjects.

Objective:To study the distribution of TCM constitutions in maintenance hemodialysis (MHD) patients.Methods:This is a multicenter cross-sectional study. The general clinical data, dialysis-related parameters and physical and chemical examination data of MHD patients from 6 dialysis centers in Sichuan were collected. At the same time, DS01-A tongue and facial pulse information collection system was used for TCM constitution discrimination.Results:A total of 232 MHD patients were enrolled , and 417 kinds of TCM constitutions were detected, including 59 patients (25.43%) with moderate constitution and 173 patients (74.57%) with biased constitution. Phlegm-dampness was the most common type of solid constitution 47 patients (20.26%). The most common deficiency constitution was qi deficiency 86 patients (37.07%). There were certain differences in the physical distribution of patients with different gender, age, dialysis age, BMI, and whether they had diabetes, hypertension or anemia.Conclusions:The TCM constitutions of MHD patients are mainly biased constitution. Gender, age, BMI, diabetes or hypertension have a certain impact on the distribution of TCM constitutions. At the same time, different constitutions may have an impact on the anemia of MHD patients. The intervention of TCM constitutions on MHD patients may be beneficial to the prognosis of MHD patients.

ABSTRACT:OBJECTIVE To observe the differences of curative effect among superficial needle therapy,Xiakucao oral solu-tion and Vitamin E soft capsules on the breast tenderness caused by mammary glands hyperplasia and to explore the optimum therapeutic method.METHODS 105 patients with mammary glands hyperplasia were randomly divided into the superficial needling group,the Xiakucao group and the Vitamin E group,with 35 cases in every group.Patients in the superficial needling group were treated with the superficial needling retaining for 5 hours.Patients in the Xiakucao group and the Vitamin E group took medicine with oral administration.Treatment in the three groups all began from 7 ± 3 days before menstruation and stopped during menstruation.The superficial needling group was treated once every other day with total 3 times.Patients in the Xiakucao group took medicine twice a day in the morning and evening.The Vitamin E group was treated once a day.Com-pare the scores of short form McGill pain Questionnaire(SF-MPQ) before and after the treatment and after one month follow-up.Record the time needed for pain relieving in the first treatment of the superficial needling group and the adverse effects in the three groups.RESULTS After the treatment,the breast tenderness was improved obviously in the three groups (P <0.01)and the superficial needling group was superior to the other groups(P <0.01).During the one-month follow up,the su-perficial needling group showed good effects(P <0.01).It also showed fast effect on relieving the pain in the first treatment. The Xiakucao group was superior to the Vitamin E group in the improvement of the breast tenderness(P <0.05).CONCLU-SION The superficial needling therapy shows fast and lasting effects on relieving the pain of mammary glands hyperplasia, which is superior to Xiakucao oral solution and Vitamin E soft capsules.

·AIM: To evaluate the effect of bupivacaine in non-catheter infiltration anesthesia during vitretomy operation.·METHODS:Fifty-eight patients (58 eyes) with vitreous retinal surgery were selected. Patients were randomly divided into observation group ( 28 eyes ) and control group ( 30 eyes ) . The observation group were received non-catheter infiltration anesthesia. The control group were received traditional Sub- Tenon's block ( STB ) . Degree of pain, basic vital signs, the duration of anesthesia and analgesia grade were recorded and compared between two groups.·RESULTS: No significant difference was found in the 11-point numeric rating scale ( NRS - 11 scoring ) of anesthesia process, sclera incision, intraocular operation and the end of operation between two groups (P>0. 05). The difference were not significant in heart rate and blood pressure between two groups(P>0. 05). There was statistically significant difference in the duration of anesthesia between two groups (P<0. 05).·CONCLUSION: Both groups can provide the same anesthetic effect. Compared to STB, non - catheter infiltration anesthesia takes short time, and it is a safe and effective anesthesia methods. In addition, compare to the mixture of bupivacaine and lidocaine injection, bupivacaine injection can provide the same anesthetic effect.

Objective: To examine the association of body mass index (BMI) and waist circumference (WC) with frailty among oldest-old adults in China. Methods: A total of 7 987 people aged 80 years and older (oldest-old) who participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2017-2018 were included. Information on demographic characteristics, behavior pattern, diet, activities of daily living, cognitive function, health status, disease condition were collected by questionnaire and physical examination. Generalized linear mixed model and restricted cubic splines (RCS) were used to analyze the association of BMI and WC with frailty. Results: The mean age of all participants was 91.7 years, and their mean BMI and WC were (21.3±3.5) kg/m² and (82.9±10.5) cm, respectively. The proportion of male was 42.3% (3 377/7 987), and the proportion of people with frailty was 33.7% (2 664/7 987). After controlling confounding factors, compared with T₂ (19.1-22.1 kg/m²) of BMI, the OR (95%CI) of the female T₁ (<19.1 kg/m²) and T₃ (≥22.2 kg/m²) group was 1.39 (1.17-1.65) and 1.27 (1.07-1.52), respectively. Compared with T₂ (77-85 cm) of WC, the OR (95%CI) of female T₁ (<77 cm) and T₃ (≥86 cm) group was 1.20 (1.01-1.42) and 1.10 (0.93-1.31), respectively. The results of multiple linear regression model with restrictive cubic spline showed that there was a non-linear association of BMI and WC with frailty in female. Conclusion: There is a U-shaped association of BMI and WC with frailty in female participants.
