AIM: To investigate the therapeutic effect of optimal pulse technology combined with tea tree essential oil paste in the treatment of Demodex blepharitis.

METHODS: Prospective clinical study. Totally 283 patients(566 eyes)with Demodex blepharitis were selected and randomly divided into three groups. Group A(94 cases, 188 eyes)was treated with optimal pulse technology, group B(96 cases, 192 eyes)was treated with tea tree essential oil paste, and group C(93 cases, 186 eyes)was treated with optimal pulse technology combined with tea tree essential oil paste. After 6wk of treatment, the number of Demodex, subjective symptom score, clinical sign score, tear film rupture time and corneal fluorescein staining were analyzed.

RESULTS: There was no significant difference in Demodex count, symptom score, sign score, tear film rupture time and corneal fluorescein staining among the three groups before treatment(P>0.05). After treatment, the number of Demodex among the three groups were significantly reduced(P<0.05), and there were significant differences among group C, group A and group B(P<0.05). The scores of subjective symptoms and signs of the three groups were significantly improved after treatment(P<0.05), and the improvement of group C was more significant than that of group A and group B(P<0.05). After treatment, tear break-up time of the group B not significantly improved, tear break-up time that of group C was significantly longer than that of groups A and B(P<0.05); Fluorescent staining scores of three groups before and after treatment were significantly improved(P<0.05). The statistical results of group C were better than those of groups A and B, but there was no difference among the three groups. No obvious complications occurred in all patients.

CONCLUSION: The effect of optimal pulse technology combined with tea tree essential oil in the treatment of acariasis blepharitis is significant, which is significantly better than that of single optimal pulse technology therapy and single use of tea tree essential oil.

Accurately assessing and positioning the current development status of disciplines can help hospitals formulate targeted disciplinary development strategies and achieve disciplinary development goals. In 2022, a large tertiary public hospital established a discipline-demand-oriented " pyramid" hierarchical discipline evaluation system based on Maslow′s need-hierarchy theory. The discipline evaluation system set six levels of evaluation indicators from low to high, including medical quality and safety, department operation, sub specialty construction, scientific and educational achievements, platform construction, and talent cultivation(including 6 primary indicators, 21 secondary indicators, and 44 tertiary indicators). By applying the evaluation system and providing feedback on the evaluation results in the form of " disciplinary diagnostic reports" and " disciplinary evaluation conferences, " the hospital′s discipline construction had been improved at six levels. From 2022 to 2023, the hospital added five national clinical key specialties; The number of sub major construction disciplines increased from 18 in 2021 to 61 in 2023, and patient satisfaction increased from 94.64% to 96.25%. This evaluation system could objectively reflect the level of discipline development, lead the high-quality development of disciplines, and provide references for other public hospitals to promote discipline development.

Objective:Investigate and analyze the etiology and serological diagnosis capabilities of pertussis in medical institutions in Shandong Province in 2018.Methods:Using the census method, a questionnaire survey was conducted among 603 second and above level medical institutions in Shandong Province. The deadline for the survey was December 2018, and a total of 543 questionnaires have been recovered, and the validity rate of the questionnaires was 90%. Surveyed the pertussis etiology and serology test items (pertussis IgM and IgG, pertussis nucleic acid and pertussis bacterial culture) and the start time of each test item by questionnaire. The reported cases (confirmed cases and clinically diagnosed cases) between January 1, 2012 and December 31, 2018 were derived from the Chinese Disease Control and Prevention Information System according to the onset date. We used indicators such as fixed-base development speed, chain development speed, and chain growth speed for analysis. The chi test was used to analyze the differences in the composition ratio of medical institutions with detection ability in different levels and regions, and analyze the changes in the number of reported cases before and after the development of pertussis etiology and serology testing.Results:A total of 543 medical institutions accounted for 90.0% (543/603) of all secondary and above level medical institutions in the province, 356 secondary medical institutions (65.6%), and 187 tertiary medical institutions (34.4%). There were 10 medical institutions that carry out pertussis IgM, IgG and nucleic acid testing, accounting for 1.8% (10/543) of the surveyed medical institutions respectively. 2 medical institutions that carried out bacterial culture, accounting for 0.4% of the surveyed medical institutions (2/543). 20 medical institutions have carried out the above tests (8 secondary medical institutions and 12 tertiary medical institutions), accounting for 3.7% (20/543). The proportion of tertiary medical institutions with pertussis IgM, IgG detection and nucleic acid detection capabilities [6.42% (12/187)] was significantly higher than that of secondary medical institutions [2.25% (8/356)] ( χ2=6.01, P=0.014). From 2012 to 2018, the fixed base ratio development speed of reported cases was 3 834.69% in Shandong Province, among which medical institutions with etiology and serological testing capabilities reached 4 533.33%. In 13 medical institutions, the average annual number of reported cases after pertussis etiology and serological testing were higher than that of reported cases before testing. Conclusion:The ability of pertussis etiology and serology diagnosis of secondary and above medical institutions in Shandong Province needs to be improved.

Objective To analyze the clinical value of postoperative radiotherapy for node-positive middle thoracic esophageal squamous cell carcinoma ( TESCC ) and to modify the target volume .Methods A total of 286 patients with node-positive middle TESCC underwent radical surgery in Cancer Hospital, Chinese Academy of Medical Sciences, from 2004 to 2009.In addition, 90 of these patients received postoperative intensity-modulated radiotherapy.The Kaplan-Meier method was used to calculate survival rates, and the log-rank test was used for survival difference analysis.The Cox model was used for multivariate prognostic analysis.The chi-square test was used for comparing the recurrence between patients receiving different treatment modalities.Results The 5-year overall survival ( OS) rates of the surgery alone ( S) group and surgery plus postoperative radiotherapy ( S+R) group were 22.9%and 37.8%, respectively, and the median OS times were 23.2 and 34.7 months, respectively ( P=0.003) .For patients with 1 or 2 lymph
node metastases (LNMs), the 5-year OS rates of the S group and S+R group were 27.3%and 44.8%, respectively ( P=0.017);for patients with more than 2 LNMs, the 5-year OS rates of the S group and S+R group were 16.7%and 25.0%, respectively (P=0.043).The peritoneal lymph node metastasis rates of N1 , N2 , and N3 patients in the S group were 2.9%, 10.9%, and 20.0%, respectively ( P=0.024) .The S+R group had a significantly lower mediastinal lymph node metastasis rate than the S group ( for patients with 1 or 2 LMNs:8.0%vs.35.3%, P=0.003;for patients with more than 2 LNMs, 10.0%vs.42.3%, P=0.001) , and had a prolonged recurrence time compared with the S group ( 25.1 vs.10.7 months, P=0.000) .However, for patients with more than 2 LNMs, the S+R group had a significantly higher hematogenous metastasis rate than the S group (46.7%vs.26.1%, P=0.039).Conclusions Patients with node-positive middle TESCC could benefit from postoperative radiotherapy.The target volume can be reduced for patients with 1 or 2 LNMs.Prospective studies are needed to examine whether it is more appropriate to reduce the radiotherapy dose than to reduce the target volume for patients with more than 2 LNMs.A high hematogenous metastasis rate warrants chemotherapy as an additional regimen.

[ Abstract] Objective To investigate the clinical efficacy of preoperative three-dimensional radiotherapy (3DRT) with or without concurrent chemotherapy for esophageal carcinoma.Methods We retrospectively analyzed 103 esophageal carcinoma patients who received preoperative 3DRT with or without concurrent chemotherapy from 2004 to 2014 in Cancer Hospital CAMS.The median radiation dose was 40 Gy, and the TP or PF regimen was adopted for concurrent chemotherapy if needed.The overall survival (OS) and disease-free survival ( DFS) were calculated by the Kaplan-Meier method, and the survival difference and univariate prognostic analyses were performed by the log-rank test.The Cox proportional hazards model was used for multivariate prognostic analysis.Results The number of patients followed at 3-years was 54.The 3-year OS and DFS rates were 61.1% and 54.9%, respectively, for all patients.There were no significant differences between the 3DRT and concurrent chemoradiotherapy (CCRT) groups as to OS (P=0.876) and DFS (P=0.521).The rates of complete, partial, and minimal pathologic responses of the primary tumor were 48.0%, 40.2%, and 11.8%, respectively.There were significant differences in OS and DFS between the complete, partial, and minimal pathologic response groups (P=0.037 and 0.003). No significant difference in pathologic response rate was found between the 3DRT and CCRT groups (P=0.953).The lymph node metastasis rate was 26.5%, and this rate for the complete, partial, and minimal pathologic response groups was 14%, 30%, and 67%, respectively, with a significant difference between the three groups (P=0.001).The OS and DFS were significantly higher in patients without lymph node metastasis than in those with lymph node metastasis (P=0.034 and 0.020).The surgery-related mortality was 7.8% in all patients.Compared with the 3DRT group, the CCRT group had significantly higher incidence rates of leukopenia (P=0.002), neutropenia (P=0.023), radiation esophagitis (P=0.008), and radiation esophagitis ( P=0.023).Pathologic response of the primary tumor and weight loss before treatment were independent prognostic factors for OS and DFS (P=0.030,0.024 and P=0.003,0.042). Conclusions Preoperative 3DRT alone or with concurrent chemotherapy can result in a relatively high complete pathologic response rate, hence increasing the survival rate.Further randomized clinical trials are needed to confirm whether preoperative CCRT is better than 3DRT in improving survival without increasing the incidence of adverse reactions.

Objective: To study the fatigue symptoms of adult patients with primary immune thrombocytopenia (ITP) and to analyze the possible factors that affect the severity of fatigue. Methods: Eligible adult patients with ITP who admitted to Institute of Hematology & Blood Diseases Hospital were enrolled in this study and the questionnaires including a Chinese version of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) , the Pittsburgh sleep quality index (PSQI) , the Hospital Anxiety and Depression scale (HADS) and demographic information were completed. The predictors of fatigue were determined with multiple linear regression analyses. Results: A total of 207 patients with ITP were enrolled, including 70 males (33.8%) and 137 females (66.2%) , the median age was 42 (18-72) years old. The FACIT-F score in ITP patients was (37.50±9.05) . The FACIT-F severity of ITP patients was positively correlated with the platelet count (r=0.307, P<0.001) . The FACIT-F severity was negatively correlated with bleeding severity (r=-0.276, P<0.001) , sleep quality (r=-0.654, P<0.001) , depression (r=-0.598, P<0.001) and anxiety (r=-0.616, P<0.001) . A multiple linear regression analysis revealed that the severity of ITP-related fatigue was significantly correlated with platelet count (P<0.001) , bleeding severity (P=0.004) , sleep quality (P<0.001) and depression (P<0.001) . Conclusion Fatigue was determined by complicated factors in adult ITP patients. Interventions addressing depressive symptoms, sleep quality, bleeding symptoms and platelet count could be potential avenues for treatment of fatigue in patients with ITP.

Objective:To investigate the risk factors for abdominal infection after liver transplantation (LT).Methods:The retrospective case-control study was conducted. The clinical data of 356 patients who underwent LT in the First Affiliated Hospital of Xi′an Jiaotong University from January 2015 to December 2018 were collected. There were 273 males and 83 females, aged from 21 to 67 years, with the median age of 46 years. Observation indications: (1) abdominal infec-tion after LT and distribution of pathogens; (2) analysis of risk factors for abdominal infection after LT; (3) follow-up and survival. Follow-up was performed using outpatient examination and tele-phone interview to detect postoperative 1-year survival rate and cases of death up to June 2020. Measurement data with normal distribution were represented as Mean±SD. Measurement data with skewed distribution were described as M(range). Count data were expressed as absolute numbers or percentages. Univariate analysis was conducted using the chi-square test, t test, Mann-Whitney U test and Fisher exact probability. Multivariate analysis was done using the Logistic regression model. The Kaplan-Meier method was used to calculate sruvival time and survival rates. Log-Rank test was used for survival analysis. Results:(1) Abdominal infection after LT and distribution of pathogens: 63 of 356 recipients had abdominal infection after LT, with the overall incidence of 17.70%(63/356). Of the 63 recipients, 41 cases had abdominal infection within postoperative 2 weeks, 17 cases had multi-drug resistant organism infection. A total of 116 strains of bacteria were isolated from 63 recipients with abdominal infection, 52 of which were gram-negative bacteria, 48 were gram-positive bacteria, 16 were fungi. (2) Analysis of risk factors for abdominal infection after LT: results of univariate analysis showed that preoperative model for end-stage liver disease (MELD) score, preoperative serum albumin, preoperative leukocytes, preoperative prothrombin time, preoperative alanine aminotransferase, preoperative aspartate aminotransferase, operation time, volume of intraoperative blood loss, days of postoperative antibiotic use, postoperative renal failure, postoperative delayed graft function,duration of postoperative intensive care unit stay were related factors for abdominal infection after LT ( Z=-2.456, t=-1.982, Z=-3.193, -2.802, -2.336, -2.276, -2.116, -3.217, χ2=15.807, 10.395, 6.750, Z=-4.468, P<0.05). Liver retransplantaiton and postoperative bile leakage were related factors for abdominal infection after LT ( P<0.05). Results of multivariate analysis showed that preoperative MELD score>20 and liver retransplantation were independent risk factors for abdominal infection after LT ( odds ratio=2.871, 12.875, 95% confidence interval as 1.106-7.448, 1.290-128.521, P<0.05). (3) Follow-up and survival: 356 recipients were followed up for 1-66 months, with a median follow-up time of 32 months. The postoperative 1-year overall survival rate of 63 recipients with abdominal infection and 293 recipients without abdominal infection were 84.60% and 97.03%, respectively, showing a significant difference ( χ2=11.660, P<0.05). During the follow-up, 58 recipients died. Conclusion:Preoperative MELD score>20 and liver retransplantation are independent risk factors for abdominal infection after LT.

Objective:To analyze the intensity and epidemiological characteristics of hepatitis B virus (HBV) reactivation among inactive HBsAg carriers (IHC) of rural areas in Ji'nan.Methods:In 2018 and 2020, follow-up investigations were conducted on IHC identified in the population physical examination in Zhangqiu district of Ji'nan. The results of the two follow-up visits were compared to analyze the incidence and distribution characteristics of HBV reactivation in IHC at the community level.Results:A total of 424 IHC completed two follow-up visits, and 47 cases of HBV reactivation were found, the cumulative reactivation rate was 11.08%, and the incidence density was 5.46/100 person-years. Multivariate analysis showed that gender, age, smoking, drinking , family history of liver disease and chronic diseases were not associated with HBV reactivation ( P>0.05), and baseline HBV DNA load was associated with reactivation ( P<0.05), in the HBV DNA level ≥1 000 IU/ml group, the reactivation rate could reach 18.92%. After reactivation, the mean level of ALT increased from baseline and the abnormal rate increased, liver function tended to be abnormal in reactivated patients. 4 (8.51%) reactivators had hepatitis, and 1 (2.13%) had jaundice hepatitis. Conclusions:The incidence of HBV reactivation was higher among IHC in rural communities in Ji'nan. Most of the reactivators were asymptomatic or mildly reactivated. Follow-up of inactive HBsAg patients should be strengthened and changes in ALT and HBV DNA levels should be closely monitored.
