Objective To construct an evaluation index system for the capability of comprehensive control of mountain-type zoonotic visceral leishmaniasis based on the One Health concept, so as to provide insights into the control and elimination of mountain-type zoonotic visceral leishmaniasis using the One Health approach. Methods A preliminary evaluation index system was constructed based on literature review, panel discussions and field surveys. Thirty-three experts were selected from 7 provincial disease control and prevention centers in Beijing Municipality, Hebei Province, Shanxi Province, Henan Province, Sichuan Province, Shaanxi Province and Gansu Province where mountain-type zoonotic visceral leishmaniasis was endemic, and two rounds of expert consultations were conducted to screen the indicators. The positive coefficient, degree of concentration, degree of coordination, and authority of the experts were calculated, and the normalized weights of each index were calculated with the analytic hierarchy process. Results The response rates of questionnaires during two rounds of expert consultation were both 100.00% (33/33), and the authority coefficients of the experts were 0.86 and 0.88, respectively. The coefficients of coordination among experts on the rationality, importance, and operability of the indicators were 0.392, 0.437, 0.258, and 0.364, 0.335, 0.263, respectively (all P values < 0.05). Following screening, the final evaluation index system included 3 primary indicators, 17 secondary indicators, and 50 tertiary indicators. The normalized weights of primary indicators “external environment”, “internal support” and “comprehensive control” were 16.98%, 38.73% and 44.29%, respectively. Among the secondary indicators of the primary indicator “external environment”, the highest weight was seen for natural environment (66.67%), and among the secondary indicators of the primary indicator “internal support”, the lowest weight was seen for the scientific research for visceral leishmaniasis control (8.26%), while other indicators had weights of 12.42% to 13.38%. Among the secondary indicators of the primary indicator “comprehensive control”, the weight was 16.67% for each indicator. Conclusions An evaluation index system has been constructed for the capability of comprehensive control of mountain-type zoonotic visceral leishmaniasis based on the One Health concept. In addition to assessment of the effect of conventional mountain-type zoonotic visceral leishmaniasis control measures, this index system integrates the importance of top-level design, organizational management, and implementation of control measures, and includes indicators related to multi-sectoral cooperation.

Objective:To investigate the role of heparin-binding protein (HBP) as a predictor of early bacterial infections in patients with traumatic intracerebral hemorrhage.Methods:Patients with traumatic intracerebral hemorrhage admitted to the Emergency Department of the First Hospital of Shanxi Medical University from September 2021 to June 2022 were collected prospectively. Patients with bacterial infection diagnosed by pathogenic examination were classified as the infected group, and those with negative pathogenic examination were classified as the non-infected group. Peripheral blood HBP counts were measured within 48 h of admission, and general information and relevant laboratory tests were collected. The differences of the indicators between the two groups were compared, the receiver operating characteristic (ROC) curve was drawn, the predictive value of the indicators for patients with co-infection was assessed, and the valuable predictors were screened out using multivariate logistic regression analysis.Results:Eighty-five patients [44 males and 41 females, aged (55.09±1.18) years] , were included in the study. Among the patients included in the study, 39 patients had bacterial infection and 46 were non-infected. Patients in the infected group were older , and had more surgeries, higher respiratory rate and injury severity score, and higher levels of HBP [(33.00±3.49) ng/mL vs. (16.27±1.61) ng/mL, P<0.001], leukocytes, and neutrophils [(15.32±3.19) ×10 9/L vs. (6.69±0.57) ×10 9/L, P=0.005] than in the non-infected group, while the Glasgow Coma Scale [(8.72±0.63) vs. (11.37±0.48), P=0.001] was lower than that in the non-infected group, with statistically significant differences (all P<0.05). There was no significant differences in lymphocytes, red blood cells, platelets, calcium, procalcitonin and coagulation indexes between the two groups (all P>0.05). Logistic regression analysis showed that neutrophils ( OR=1.252, 95% CI: 1.075-1.457, P=0.004) and HBP ( OR=1.081, 95% CI: 1.025-1.141, P=0.004) were independent risk factors for infection in patients with traumatic cerebral hemorrhage. The area under ROC curve for HBP of diagnosing early co-infection in patients with traumatic intracerebral hemorrhage was 0.82 (95% CI: 0.71-0.88), the sensitivity was 92.31%, and the specificity was 52.17%. Conclusions:HBP is a valuable predictor of early traumatic intracerebral hemorrhage complicated with bacterial infection in the emergency department, and has a good supplementary value to the existing test indicators.

Objective:To investigate the effect of epidermal growth factor receptor tyrosine kinase inhibitor on the radiosensitivity of human non-small cell lung cancer cells and its possible mechanism.Methods:Human non-small cell lung cancer cells H1299 were cultured in vitro. CCK-8 was used to detect the toxic effects of erlotinib on H1299 cells, IC 50 and IC 20 were calculated, and IC 20 was utilized as the drug concentration for subsequent experiments. The colony formation assay was performed to identifiy the effect of X-ray combined with erlotinib on H1299 cells, the radiosensitivity parameters were calculated, and the cell survival curves were delineated. Flow cytometry was conducted to detect the cell cycle distribution and apoptosis. Western blot analysis was used to detect the expression of EGFR/PI3K/AKT pathway and apoptosis-related proteins. Results:Erlotinib exerted inhibitory effect upon the proliferation of H1299 cells, IC 50 was calculated as 27.3 μmol/L, and 3.3 μmol/L for IC 20. X-ray combined with IC 20 concentration of erlotinib could reduce the cloning ability of H1299, increased the proportion of G 0/G 1 phase and G 2/M phase, decreased the proportion of S phase, aggravated cell apoptosis, down-regulated the expression of pEGFR and pAKT proteins, and up-regulated the expression of apoptosis-related proteins including Active Caspase 3 and Cleaved PARP. Conclusions:Erlotinib exerts a radiosensitizing effect on H1299. The possible mechanism is that erlotinib combined with radiation can suppress the EGFR/PI3K/AKT pathway, reduce the ability of repairing cell damage, change cell growth cycle and induce cell apoptosis.

Temporomandibular disorders (TMD) is one of the most common diseases in the orofacial region. The occurrence, development and outcome of TMD are affected by many factors. Among various risk factors, the psychological factors, especially anxiety, depression and somatic symptoms, are getting more and more attention in the etiology, diagnosis and treatment of TMD. Psychological factors are associated with the occurrence of TMD, and the accurate diagnostic criteria is conducive to the assessment of the patient′s psychological state. If necessary, an appropriate psychological treatment according to a patient′s psychological status can effectively improve the effect of clinical treatment. This article, based on domestic and international literatures, reviews the research progress of the correlation between the psychological factors and the etiology, diagnosis and treatment of TMD, in order to provide new ideas for clinicians to diagnose and treat TMD.

Objective: To discuss the feasibility and effectiveness of using micro-CT in bone-implant contact (BIC) evaluation in dogs, and to provide reference for clinical and scientific research. Methods: Bilateral mandibular second premolar and first molar of six male Beagle dogs were extracted. After 3 months′ healing, eight implants were placed in bilateral mandible of each dog, four on each side. Dogs were sacrificed at 2 weeks, 4 weeks and 8 weeks after implant placement, two on each time point. Samples were scanned with micro-CT and digitally reconstructed. Bone-implant interface was analyzed at different analysis regions (25, 50 and 100 μm from implants′ surface), different detection range models were obtained (each time point consists 48 models), and BIC was evaluated, and the results were counted as micro-CT₂₅, micro-CT₅₀, and micro-CT₁₀₀ groups. Then undecalcified slides were made (three slides for each sample) and stained with toluidine blue for observation and analysis of BIC using an optical microscope, and the results were counted as optical microscope groups. The advantages and disadvantages, evaluation efficiency and BIC of different methods were analyzed. Results: To evaluate BIC of single sample, it took about 90 minutes by micro-CT, which was much lower than the time of 14 days by optical microscope. The success rates of modeling of micro-CT₂₅, micro-CT₅₀, and micro-CT₁₀₀ groups all were 100.0% (48/48), and total success rate of micro-CT group was 100.0% (144/144). For optical microscope groups, the success rates of making slides 2, 4, 8 weeks were 89.6% (43/48), 93.8% (45/48) and 93.8% (45/48), respectively, and total success rates of optical microscope group was 92.4% (133/144). At 2, 4,8 weeks after implantation, BIC in micro-CT₂₅ group was significantly smaller than that in optical microscope group at the same time point (P<0.05). However, at 2, 4,8 weeks after implantation, BIC of the micro-CT₅₀ and micro-CT₁₀₀ groups showed no significant difference with optical microscope groups at the same time point (P>0.05). A significant correlation (P<0.001, each) was seen between slides and micro-CT (25, 50, 100 μm groups) concerning BIC (r=0.680, r=0.892, r=0.713), and error bias was -19.4%, -0.9%, 3.0%, respectively. The probability within the 95% limits of agreement were 97.9%. Conclusions Micro-CT is a faster, simpler and more efficient way to analyze BIC at the implant-bone interface than optical microscope observation. BIC analysis by selecting 50 μm from implants′ surface as analysis region using micro-CT is in consistent with that using the optical microscope.

Objective To explore the effectiveness of self-care intervention for elderly patients with diabetes mellitus in rural community. Methods We randomly selected 100 elderly patients with diabetes from January 2013 to December 2013 in rural community health service station in Yizhou, Guangxi Zhuang Autonomous Region. Individualized intervention of diabetes-related knowledge was delivered to patients. Fasting blood glucose and glycated hemoglobin were compared before and after the intervention. The effectiveness of intervention was investigated by diabetes self-care scale. Results Levels of fasting blood glucose [(5. 91 ± 0. 10)mmol/L] and glycated hemoglobin [(4. 62 ± 0. 14)%] from 100 patients were lower than those before the intervention after 1 year intervention (t=11. 840,12. 379;P<0. 01). After intervention, the total score of diabetes self-care scale was improved to (89. 66 ± 1. 56) from (75. 32 ± 1. 50) (t = -7. 597,P <0. 01). Conclusions Blood glucose can be effectively controlled by helping the rural elderly diabetic patients to learn about self-care.

To evaluate the feasibility and accuracy of contrast-enhanced ultrasonography (CEUS) for the measurement of hemodialysis access recirculation (AR) and access flow rate (Qa), a two pump system was used to simulate access and dialyzer flow. AR and Qa under different conditions, such as reversal connection of dialysis lines and the needle orientation, were compared with each other. The value of access flow and recirculation flow were calculated based on the formulas introduced in this paper, and the correlation and consistency between true flow rate and calculated values were analyzed. The measured R correlated well with true value of flow rate (r = 0.57, P = 0.038, Qa > Qb; r = 0.95, P = 0.001, Qa < Qb). The Bland-altman test showed good agreement between the calculated value based on CEUS and true values. The CEUS can be used as a new advanced technology for AR and Qa measurement.
