Objective To investigate the effects of noise from the subway cars on the preferred listening volumes using different kinds of earphones.Methods A total of 75 subjects with normal hearing were investigated to listen the same song wearing 4 kinds of earphones: insert earphones, intra-concha earphones, supra-concha earphones, and circumaural earphones, in the semi-anechoic background and inside the Line 7 subway-cars of the Beijing subway (the mean of LAeq,1s is 80.3 dB A and then selected personally preferred listening volumes.The effects of noise in the subway cars and earphone types on the preferred listening volumes were then analyzed.Results Inside subway-cars, the preferred listening levels using insert earphones, intra-concha earphones, supra-concha earphones, circumaural earphones were 76.6±4.7, 84.3±5.0, 82.3±4.2, and 80.8±4.2 dB A, respectively.The levels were respectively 65.5±6.8, 71.9±7.1, 69.5±7.5, 67.9±7.3 dB A for those in the semi-anechoic background.The preferred listening levels increase more than 10 dB averagely when stepped into noisy subway-cars background from silent background.According to the threshold levels stipulated in the WHO, to avoid hearing impairment, the daily noise exposure duration should not exceed 134 mins when exposed to subway-cars noise and the duration should not exceed 315, 54, 85, and 120 mins respectively when wearing those 4 kinds of earphones in subway-cars.Conclusion The noise and earphones types have great effects on the preferred listening volumes.The noise exposure levels in the ear canal wearing earphones with good sound insulation and listening at highly increased volume may be lower than that without earphones.

Objective To investigate the distribution of circadian typology of patients with type 2 diabetes mellitus (T2DM) and to analyze its consequent impact on glycemic control. Methods From January 2016 to June 2016, a total of 283 T2DM patients were interviewed in this study. Self designed questionnaire, Morningness-Eveningness Questionnaire (MEQ), Pittsburg Sleep Quality Index (PSQI) and Center for Epidemiological Survey-Depression Scale (CES-D) were used to collect information on diabetes history, circadian typology, sleep quality and depression. HbA1c and other biochemical indicators were determined. The glycemic control target was<7%. The 283 T2DM patients were divided into three groups:morning type group, evening type group and neither type group according to MEQ score. Results Of the 283 subjects, 97 (34.3%) were classified as morning type, 42 (14.8%) as evening type, and 144 (50.9%) as neither. Participants with evening type were younger, shorter diabetes duration, more depressive symptoms, higher perceived sleep debt, higher FBG and higher HbA1c than those with morning type. The binary Logistic regression analysis showed that HbAlc≥7%was associated with higher FBG, higher PSQI score, higher sleep debt, lower HDL-C, and lower MEQ scores (OR=0.189-2.904, all P<0.05). Conclusions Evening type was associated with higher HbA1c and poorer glycemic control in T2DM patients compared with morning type and may be one of the risk factors affecting glycemic control.

Objective:To investigate the clinical effect of using free bilateral anterolateral thigh flaps(ALTF) in series to repair large area soft tissue defects of forearm.Methods:The clinical data of 11 patients with large soft tissue defects of forearm admitted in the Department of Plastic(Repair and Reconstruction) Surgery, Lishui Hospital of Zhejiang University from March 2014 to December 2021 were retrospectively analyzed, including 8 males and 3 females. Aged 36 to 68 years old, with an average of 48 years old. VSD treatment was performed after debridement, and until fresh removed 3 to 5 days after the operation. Until the wound was fresh. The wound was repaired with free bilateral ALTF in series until fresh. The size of the forearm wound was 18 cm×15 cm-28 cm×13 cm. The cut area of a single flap was 10 cm×8 cm-20 cm×13 cm. The series of bilateral flaps: One of the flaps was used as the proximal flap, and its vascular pedicle was anastomosed with the arteries and veins of the recipient area. The other flap was used as the distal flap, and the arteries and veins between the 2 ALTFs on both sides were anastomosed. The vascular pedicle beyond the distal flap was ligated or anastomosed to the distal end of the ulnar artery or the distal end of the radial artery. The flap and the surrounding skin of the recipient area were sutured immediately. The donor sites of the flap was closed directly. Periodic and regular outpatient follow-up was performed after operation and the clinical efficacy was analyzed.Results:All the flaps successfully survived after the surgery. The postoperative follow-up lasted for 6-18 months, 12 months in average. The flaps survived well with good soft texture, without swelling, the capillary reaction time was normal, without surface ulceration, in rosy colour and restored protective sensations. The hand function of the affected limb recovered well. The wound at donor sites healed well without complications. At the last follow-up, the hand function of the affected limb was evaluated by the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, the result was 7 in excellent and 4 in good. The patients were satisfied with the flap and the therapeutic effect.Conclusion:The free bilateral ALTF in series can be used to repair a wound surface with large area, and the donor site can be closed at the same time. It is an effective method to repair large soft tissue defect of forearm.

Objective:To establish an in vitro capsular bag model and compare the inhibitory effects of different 360° square-edge intraocular lens (IOL) on lens epithelial cells (LECs) migration. Methods:In vitro capsular bag model with posterior capsule opacification (PCO) was established using Transwell compartment, cell climbing slices, human collagen type Ⅳ, and IOL.The models were divided into Plate-loop HydroSmart group, C-loop HydroSmart group, and C-compensation-loop Hydrophobic group according to the different square-edge IOL implanted.A blank control group was set using the Transwell compartment without IOL.The early PCO pathological manifestations in lens epithelial cell line SRA01/04 cultured in the Transwell compartment were observed with an inverted microscope.The cell morphology in different groups was observed by hematoxylin and eosin staining.The cell counting and cell migration inhibition rate of anterior capsule and posterior capsule were calculated by Transwell assay and cell-exclusion zone assay, respectively. Results:The early pathological characteristics of PCO, such as early Soemmering ring and small Elschnig pearl, could be found in cells in the in vitro capsular bag model after 48-hour culture.The migrating cells in model groups were fibrous.No changes mentioned above were found in blank control group.The number of migrating cells in the anterior capsule of Plate-loop HydroSmart group, C-loop HydroSmart group, C-compensation-loop Hydrophobic group was 18.80±5.53, 24.67±9.80, and 34.47±10.80, respectively, and the number of migrating cells in the optical area of the posterior capsule of the three groups was 56.43±9.00, 162.20±16.38, and 121.30±12.01, respectively.The cell migration inhibition rate in the anterior capsule of Plate-loop HydroSmart group, C-loop HydroSmart group, C-compensation-loop Hydrophobic group was (92.02±1.94)%, (89.76±3.10)%, (86.27±4.54)%, respectively, and the cell migration inhibition rate in optical area of the posterior capsule of the three groups was (91.60±3.65)%, (70.14±5.35)%, (78.43±3.48)%, respectively.The number of migrating cells in the anterior capsule was lower and the cell migration rate inhibition was higher in Plate-loop HydroSmart group than C-compensation-loop Hydrophobic group, with significant differences (both at P<0.05). The number of migrating cells in the optical area of the posterior capsule and the cell migration inhibition rate was greater than those of C-loop HydroSmart group and C-compensation-loop Hydrophobic group, showing statistically significant differences (all at P<0.001). Conclusions:The in vitro capsular bag model can be used in PCO research.Compared with C-loop HydroSmart IOL and C-compensation-loop Hydrophobic IOL, Plate-loop HydroSmart IOL can more effectively inhibit the migration of LECs to the optical area of the posterior capsule.
