Background How to control progression of myopia is a central issue in clinical optometry.Some clinical trials showed that wearing base-in (BI) prism can slow down progression of myopia to certain degree.However,whether BI prism or base-out (BO) prism should be used is worth discussing.Objective This study was to investigate the influences of different prisms on accommodative response and microfluctuation in emmetropias.Methods This clinical trail was approved by Ethic Committee of Peking University People's Hospital.During July in 2014,twenty-two emmetropias of 22 normal volunteers aged 21-27 years were recruited from Peking University People's Hospital under the written informed consent.An open-field infrared refractometer was used to monitor and record pupil diameter and accommodative response under three conditions including non-prism,3△ BI prism,and 3△ BO prism.The accommodative response value was calculated as the difference between reading value and-3.0 D,and root mean square (RMS) of accommodative response value served as amplitude of accommodative microfluctuation.Spectrum of accommodative response was analyzed by one dimension discrete Fourier transformation.The differences of accommodative response value,amplitude of accommodative microfluctuation and pupil diameter among three conditions were compared using repeated one-way ANOVA.Results The accommodative response values were (+0.31±0.78),(+0.51±0.75) and (+0.18±0.72) D under the non-prism,3△BI prism and 3△BO prismconditions,respectively,with a significant difference among them (F =28.078,P =0.000),and compared with the non-prism condition,the accommodative lag of 3△BI prism condition was increased and that of 3△BO prism condition was reduced (P =0.000,0.012).No significant difference was found in the amplitude of accommodative microfluctuation among the three conditions (F=0.062,P =0.879).The percentages of low frequency signal power (0-0.5 Hz)/total power (0-2.5 Hz) was 97.5％,98.3％ and 91.4％ under the non-prism,3△BI prism and 3△BO prism condition,respectively.The pupil diameter was (5.37-±0.69) mm under the 3 △ BI prism condition,which was larger than (5.07±0.66) mm under the non-prism condition and (5.01 ±0.69) mm under the 3△ BO prism condition (both at P =0.000).Conclusions Compared with wearing 3△ BI prism,wearing 3△ BO prism lessens the accommodative lag,decreases the pupil diameter and reduces the power of low frequency component in accommodative response.

Objective: To analyze the medical care seeking of local and non-local pulmonary tuberculosis (TB) patients in Beijing from 2016 to 2021 and provide evidence for TB prevention and control in Beijing. Methods: The reported pulmonary TB data from 2016 to 2021 were collected from tuberculosis management information system and standard code management system of Chinese information system for disease control and prevention. The map data were obtained from the Institute of Geographic Sciences and Natural Resources Research. Excel 2016, SPSS 19.0, Python 3.9 and ArcGIS 10.6 softwares were used for data analysis and visualization for the inter-provincial mobility and inter-district mobility of pulmonary TB patient's medical care seeking in Beijing. Results: Among the reported pulmonary TB patients in Beijing from 2016 to 2021, 35.27%(24 307/68 926) were from 30 provinces (autonomous regions, municipalities) and Xinjiang Production and Construction Corps. The top 5 provinces with pulmonary TB patients medical care seeking in Beijing were Hebei (39.58%,9 620/24 307), Shanxi (8.82%,2 145/24 307), Inner Mongolia Autonomous Region (8.66%,2 105/24 307), Heilongjiang (6.95%,1 690/24 307) and Henan (6.88%,1 672/24 307). Patients from these 5 provinces accounted for 70.89% (17 232/24 307) of total pulmonary TB patients from other provinces. The pulmonary TB patients from other provinces mainly flowed to Tongzhou district of Beijing, accounting for 46.72% (11 356/24 307). These pulmonary TB patients mainly visited grade Ⅲ (A) hospitals, such as Beijing Chest Hospital of Capital Medical University with the highest proportion of 44.76% (10 880/24 307). Among pulmonary TB patients with current residence in Beijing, those sought medical care in other districts accounted for 55.06% (24 566/44 619). The outflow and inflow of TB cases' medical care seeking occurred in 16 districts of Beijing. The median proportion of cross district medical care seeking in 16 districts was 59.30% (56.05%, 65.13%). The inflow of the medical care seeking in Tongzhou, Haidian and Xicheng district was greater than the outflow, and the outflow was greater than the inflow in the other 13 districts. The pulmonary TB patients in Beijing mainly went to Beijing Chest Hospital in Tongzhou for medical care seeking, accounting for 42.18%(18 822/44 619). Conclusions: The proportions of non-local pulmonary TB patients seeking medical care in Beijing from 2016 to 2021 and local pulmonary TB patients seeking medical care in other districts in Beijing were high, and the hospitals where non-local pulmonary TB patients and local pulmonary TB patients sought medical care respectively belonged to grade Ⅲ (A) and municipal designated medical institutions of TB.

Pathological findings included 8 cases of squamous cell carcinoma, 4 cases of basal cell carcinoma and 1 case of fibrosarcoma. Using Mohs method resect the skin tumor (Rapid pathology intraoperatively to ensure lesion was all removed ). According to the diameter and location of the defect, the mandibular Flap was used to repair the large scale defects in a one-stage operation. Results: All mandibular Flap survived. During a follow-up period from 6 to 24 months, all patients obtained excellent functional and aesthetic result, and none had local recurrence. Conclusions The flexible application of mandibular Flap can basically solve the problem of repairing a large area of facial skin and soft tissue defect in zygomatic, buccal and parotid masseter of the face, which is one of the ideal methods to repair the tissue defects after resection of facial malignant tumor for the middle and old age.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
