Background Blepharitis caused by Demodex infestation is very common in clinical practice.There are various methods mentioned in the study of Demodex infestation in China,but a unified introduction and evaluation of the operating procedures is lacked.A quick and accurate clinical diagnostic method for Demodex infestation needs to be further studied.Objective This study aimed to establish operation procedures for the clinical examination of eyelid Demodex infestation,which were applied to evaluate the conditions of eyelid Demodex infestation in ocular patients with discomfort.Methods One thousand and fifty-two patients with eye dryness,eye itchiness or other symptoms were selected for slit lamp examination and photographing of the eyelid margin area.Three eyelashes with associated scurf from each superior eyelid were plucked out for examination of Demodex under the microscope.Positive findings included observation of Demodex mites or eggs.Their amounts were recorded individually for all eyelash samples.Results A procedure for observing,recording and reporting eyelid Demodex infestations in patients was successfully established.By using this procedure,1 052 patients were investigated for the examination of Demodex infestations.Demodex mites or eggs were found in 582 cases (55.3％).The positive rate of Demodex infestation increased with age,and the population over 60 years group had the highest positive rate,showing a significant difference among the different age groups (x2=10.547,P=0.001).There was no significant difference in positive rate between male patients and female patients (P =0.352).The test turnaround time (TAT) for one examination was (11.4±5.2) seconds.Conclusions The operational procedure for examining the palpebral margin Demodex infestation by the slit-lamp,optical microscope,photographing and laboratory reports is established.It is simple and quick in the appliation for the clinical diagnosis of eyelid Demodex infestation.

Objective:To investigate the influencing factors of textbook outcomes in liver surgery (TOLS) after radical resection of gallbladder carcinoma.Methods:The retrospective case-control study was conducted. The clinicopathological data of 530 patients who underwent radical resection of gallbladder carcinoma in 15 medical centers, including the First Affiliated Hospital of Army Medical University et al, from January 2014 to January 2020 were collected. There were 209 males and 321 females, aged (61±10)years. Patients underwent radical resection of gallbladder carcinoma, including cholecystectomy, hepatectomy, invasive bile duct resection, and lymph node dissection. Observation indicators: (1) situations of TOLS; (2) influencing factors of TOLS. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Mann-Whitney U test. The univariate analysis was conducted using the corresponding statistical methods based on data type, and variables with P<0.10 were included in multivariate analysis. Multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Situations of TOLS. All 530 patients underwent radical resection of gallbladder carcinoma, and there were 498 cases achieving R 0 resection, 508 cases without ≥grade 2 intra-operative adverse events, 456 cases without postoperative grade B and grade C biliary leakage, 513 cases without postoperative grade B and grade C liver failure, 395 cases without severe com-plications within postoperative 90 days, 501 cases did not being re-admission caused by severe com-plications within postoperative 90 days. Of the 530 patients, 54.53%(289/530) of patients achieved postoperative TOLS, while 45.47%(241/530) of patients did not achieve postoperative TOLS. (2) Influencing factors of TOLS. Results of multivariate analysis showed that American Society of Anesthesiologists classification >grade Ⅱ, preoperative jaundice, T staging as T3?T4 stage, N staging as N2 stage, liver resection as right hemi-hepatectomy, and neoadjuvant therapy were independent factors influencing TOLS in patients undergoing radical resection of gallbladder carcinoma ( odds ratio=2.65, 1.87, 5.67, 5.65, 2.55, 3.34, 95% confidence interval as 1.22?5.72, 1.18?2.95, 2.51?12.82, 2.83?11.27, 1.41?4.63, 1.88?5.92, P<0.05). Conclusion:American Society of Anesthesiologists classification >grade Ⅱ, preoperative jaundice, T staging as T3?T4 stage, N staging as N2 stage, liver resection as right hemi-hepatectomy, and neoadjuvant therapy are independent factors influencing TOLS in patients undergoing radical resection of gallbladder carcinoma.
