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 verify the reliability and validity of the Youth Quality of Life-Deafness Specific Scale (YQOL-DHH) in Chinese version. Methods In order to local and revise the YQOL-DHH, 193 deafnessadolescents were selected as the research objects by convenient sampling. The Chinese version ofYQOL-DHH and WHOQOL-DIS Scales for PD were applied to carry out the investigation. Results 32 items of the original scale were reserved in the Chinese version of the YQOL-DHH.By exploratory factor analysis, the scale could be divided intoself-acceptance, stigma and social participation, which could explain 76.8％ of variability; there was a significant correlation between the factors and the total score (P<0.01);the total content validity of the scale was 0.95;the score of the scale was significantly correlated with the correlation coefficient of WHO-DIS score (P<0.01). The Cronbachαcoefficient of the scale was 0.911 and the test-retest correlation coefficient was 0.634. Conclusions The Chinese version of YQOL-DHH has good reliability and validity, which can be used to measure the quality of life of deafnessyouth.

Objective: To explore the application effect of tarso-conjunctival flap for one-stage repairing eyelid posterior defect after resection of eyelid tumors. Methods: From June 2014 to December 2016, 33 patients with 33 cases of eyelid posterior tumors were treated, including 21 cases of Pigmented nevus of eyelid, 7 cases of eyelid basal cell carcinoma, 3 cases of eyelid adenocarcinoma and 2 cases of eyelid squamous cell carcinoma. Direct resection was performed for eyelid nevus, Mohs method (intraoperative delivery of frozen sections to control the cut edge) resection was performed for malignant tumors. According to the scope and location of the defect, the tarso-conjunctival flap was used to repair the posterior defect of the eyelid, and the eyelid anterior defect was treated with local flap transfer. Results: All 33 patients were followed up for 3 to 24 months. In addition to the absence of eyelashes in the defect area, one case had mild blepharoptomy (1 mm) and recovered after self-recovery. The remaining cases had recovered in appearance and function of eyelid with no serious complications. Conclusions The flexible application of tarso-conjunctival flap can basically solve the problem of repairing eyelid posterior defect after resection of eyelid tumors. The operation method has clinical practical value.

Objective: To explore the effect of the mandibular flap application on one-stage repairing facial large defects after resection of skin tumors. Methods: Thirteen patients with malignant facial skin tumors were treated from June 2016 to June 2018 in Taizhou First Hospital department of Plastic Surgery. The lesion included zygomatic in 3 cases (including 2 cases of non-adjacent defects in zygomatic area), buccal area area in 2 cases, parotid masseter in 6 cases and compound area in 2 cases. 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.

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.
