Background With the changes of diet and living style,the diabetes has become the major diseases affecting human health.Diabetic cataract is a common complication of diabetes. Objective The present study was to investigate the difference of lens proteomics between diabetic cataract and age related cataract using two dimensional electrophoresis (2-DE) and mass spectrometry in order to postpone happening of diabetic cataract and offer the effective approach to the prevention and therapy of diabetic cataract. Methods The lenses were obtained from 8 diabetic patients and 12 age-related cataract patients during the surgery to extract the protein by lysis and centrifugation.The lens proteins were separated using immobilized pH gradients 2-DE.Image analysis was carried out using PDQuest Advanced-8.0.1 software package.Significant difference of the crystallines was identified by matrixassisted laser adsorption/ionization time of-flight-mass spectrometry (MALDI-TOF-MS) and peptide mass fingerprint combined with protein database. Results The maps of 2-DE showed that lens proteins of diabetic cataract and age related cataract were in the section of pH 5-9 with the relative molecular weight 14000-97000;while relative molecular weight of more abundant crystalline was localized at 20000-31000.About 3 differential protein spots were detected by image analysis software.Two crystallines,αB and βB1 crystallin,were identified using MALDI-TOF-MS.Conclusions Proteomic analysis of lens can be accomplished and the proteins can be well separated,moreover,differential proteins can be analyzed using 2-DE and mass spectrometry between diabetic cataract and age related cataract.These results indicate that αB and βB1 crystallin proteins accelerate the development of diabetic cataract.This technique offers a new avenue for clarity of lens proteins of diabetic cataract other than age related cataract.

Objective:
To evaluate the effectiveness of the SHARP intervention model for increasing students’ moderate to vigorous physical activity (MVPA) levels,and to provide a reference for physical activity enriching intervention among middle schools students’.
Methods:
One-year interventional teaching was carried out in 6 schools selected in the terms of scale and demographics from Nanjing City, Jiangsu Province. Data were collected during physical education (intervention group 105, control group 113; pre-intervention 119, post-intervention 99) data for 218 students. MVPA was assessed at baseline and post-intervention using the Observed Health and Coaching Time System(SOFIT). Interviews with 19 teachers were conducted with intervention schools to explore teachers’ views on interventions.
Results:
The two-way analysis of variance showed that the intervention of the SHARP model had a significant impact on MVPA, VPA, and motor skills of middle school students. Proportion of the average MVPA class time of the intervention school students(62.80±9.11), and the average proportion of the VPA class time of the intervention school(24.33±12.55), the average class time for intervention in the school’s mastery of skills(32.34±11.78)(t=-7.46, -4.82, -12.08, P<0.01). The MVPA of students in control school remained relatively constant while the VPA decreased. Classroom teaching capability improved significantly in intervention schools, which was further confirmed by teacher interviews.
Conclusion
The SHARP intervention model can effectively increase the MVPA level of middle school students.

Objectives To screen the high-risk population of stroke in China using color Doppler flow imaging (CDFI)and to establish a stroke risk prediction model in Chinese population in order to prevent and treat stroke early. Methods Forty-one base hospitals and 715 286 people in the project areas of the first 6 provinces of China conducted routine physical examinations and investigated the related risk factors for cardiocerebrovascular diseases from July 2011 to April 2012 using a cross-sectional study,among them 61 860 patients underwent carotid CDFI screening,and 49 386 of them were high-risk population (exposed to≥3 risk factors). The bilateral common carotid interma-media thickness (IMT),the number of plaques and the degree of carotid stenosis were screened and documented. And whether carotid IMT thickening or not,with or without carotid plaques,and degree of carotid artery stenotic rate 0-49% and≥50% were performed by multivariate logistic regression analysis with the risk factors for stroke,respectively. Results (1)Logistic regression analysis showed that hypertension,atrial fibrillation,smoking,and lack of physical exercise were the independent risk factors for carotid IMT thickening (hypertension:OR,1. 17;95%CI 1. 12-1. 22;atrial fibrillation:OR,1. 15;95%CI 1. 09-1. 21;smoking:OR,1. 13;95%CI 1. 08-1. 17;and lack of physical exercise:OR,1. 12;95%CI 1.08-1. 16). (2)Hypertension,atrial fibrillation, smoking,and diabetes were the independent risk factors for carotid plaque and carotid artery stenosis rate≥50%(carotid plaque,hypertension:OR,1. 55;95%CI 1. 47-1. 62;atrial fibrillation:OR,1. 13;95%CI 1.06-1. 21;smoking:OR,1. 16;95%CI 1. 11-1. 22;and diabetes:OR,1. 30;95%CI 1. 24-1. 37). Carotid stenosis rate≥50%,hypertension:OR,1. 78;95%CI 1.55-2. 03;atrial fibrillation:OR,1. 59;95%CI 1. 39-1. 81;smoking:OR,1. 33;95%CI 1. 20-1. 48;and diabetes:OR,1. 30;95%CI 1. 17-1. 45. Simple obesity did not increase the incidences of carotid atherosclerotic plaque and carotid artery stenosis ≥50%(OR,0. 78, 0.83;95%CI 0. 75-0. 82 ,0. 75-0. 92,respectively).

OBJECTIVETo examine the changes in 25-hydroxyvitamin D[25-(OH)D] level in children with Henoch-Schönlein purpura (HSP) and its clinical significance.
METHODSA total of 92 HSP children were included in this study, and were divided into HSP nephritis (HSPN) group (31 cases) and HSP group (61 cases) based on the presence or absence of HSPN. Alternatively, the patients were divided into purpura alone group (22 cases), purpura with joint symptoms group (joint symptom group, 24 cases), purpura with gastrointestinal symptoms group (gastrointestinal symptom group, 20 cases), and purpura with joint and gastrointestinal symptoms (mixed group, 26 cases) based on their clinical symptoms. In addition, 42 healthy children were selected as healthy control group. The level of 25-(OH)Din each group was measured using enzyme-linked immunoassay.
RESULTSThe 25-(OH)Dlevel in the HSP and HSPN groups was significantly lower than that in the healthy control group (P<0.05), and the 25-(OH)Dlevel in the HSPN group was significantly lower than that in the HSP group (P<0.05). Although there was no significant difference in the 25-(OH)Dlevel between the joint symptom, gastrointestinal symptom, and mixed groups (P=0.22), the 25-(OH)Dlevel in the three groups was all significantly lower than that in the purpura alone group (P<0.05).
CONCLUSIONSThe level of 25-(OH)Dis reduced in children with HSP, particularly those with HSPN or with joint and gastrointestinal symptoms. Therefore, the reduction in 25-(OH)Dlevel may serve as a predictor of whether HSP is associated with other impairments.

Objective: To compare the therapeutic efficacy between warm needling moxibustion and electroacupuncture (EA) in the treatment of simple obesity due to yang deficiency of the spleen and kidney. Methods: Seventy patients with simple obesity due to yang deficiency of the spleen and kidney were randomly divided into a warm needling moxibustion group and an EA group, with 35 subjects in each group. Same major acupoints were selected for the two groups, including Shuifen (CV 9), Guanyuan (CV 4), Daheng (SP 15), Shuidao (ST 28), Shousanli (LI 10), Zusanli (ST 36), Sanyinjiao (SP 6) and Taixi (KI 3). The warm needling moxibustion group received warm needling moxibustion, while the EA group received EA treatment. The interventions were performed once every other day, with 15 treatments as one course. The therapeutic efficacy, body weight and body mass index (BMI) were then observed and compared. Results: The total effective rate in the warm needling moxibustion group was 85.7% versus 77.1% in the EA group, and the between-group difference was statistically significant (P<0.05). The warm needling moxibustion was remarkably superior to the EA in weight loss and lowering BMI, both with statistical significance (P<0.05, P<0.01). At the three-month follow-up, the body weight and BMI further decreased in the warm needling moxibustion group (both P<0.05), and the levels were lower than those in the EA group (P<0.05, P<0.01). Conclusion: Warm needling moxibustion can produce reliable and consistent efficacy in the treatment of simple obesity due to yang deficiency of the spleen and kidney. Compared with EA, warm needling moxibustion shows advantage in both short-term and long-term efficacies, and thus is worth promotion in clinical practice.

Objective:To explore the clinical features and treatment strategies of the transsyndesmotic ankle fracture dislocation.Methods:Data of 26 patients of transsyndesmotic ankle fracture dislocation who were treated in our hospital from December 2013 to November 2020 were retrospectively analyzed. There were 16 men and 10 women with an average age of 49.54±12.81 years (range, 26-68 years). Open injuries in 17 cases, of which the Gustilo-Anderson II type in 6 cases, IIIA type in 11 cases, closed injuries in 9 cases. According to the AO/OTA fracture classification, 44B type in 4 cases, 44C type in 22 cases. According to the Lauge-Hansen classification, there were 16 cases of pronation-abduction, 10 cases of pronation-external rotation, including 4 cases of Maisonneuve fractures, and of the 4 cases of Maisonneuve fractures, there were 3 cases of double Maisonneuve fracture. The talar dislocation was anterior, neutral, and posterior within the distal tibiofibular joint in 10 cases, 7 cases, and 9 cases. Fibular fractures in 26 cases, medial malleolar fractures in 24 cases, deltoid ligament rupture in 2 cases, posterior malleolar fractures in 13 cases, and anterior malleolar fractures in 8 cases. All closed injuries were closed reduction and plaster fixation and all open injuries were emergently debridement and reduced under the tibial plafond in the emergency department. Surgical treatment was taken until the soft tissue conditions to be allowed. The reduction quality was assessed by postoperative radiography according to the criteria proposed by Burwell-Charnley. The function of the ankle joint was assessed by the ankle-hindfoot rating system of the American Orthopaedic Foot and Ankle Society (AOFAS), and the posttraumatic arthritis and objectively quantified was assessed using the Kellgren-Lawrence grading scale.Results:There were 4 cases were unreduced due to the tibial posterior tendon to flip through the ankle joint and dislocate anterior to the tibia through the interosseous membrane. Stabilization of fibular fractures were achieved with plate in 25 cases. There were 24 cases of medial malleolar fractures, and the fixation were achieved with cannulated screws in 23 cases and with K-wire fixation in 1 case. There were 12 cases of posterior malleolar fractures treated with open reduction and internal fixation including cannulated screws in 9 cases and antiglide plates in 3 cases. There were 7 cases of anterior malleolar fractures treated with open reduction and internal fixation including suture anchors in 1 case and cannulated screws in 6 cases. Stabilization of syndesmosis was achieved with syndesmotic screws in 14 cases and with TightRope in 2 cases. All patients were followed up for 20.23±9.70 months (range, 12-60 months). According to the Burwell-Charnley criteria of reduction quality, anatomic reduction was obtained in 22 cases, and satisfactory reduction was gained in 4 cases. All fractures healed in 16.31±3.64 weeks (range, 10-24 weeks). Functional examination of the ankle joint (angle measurement method): dorsiflexion average angle 10.38°±6.66°, plantarflexion average angle 34.04°±7.20°. At latest follow up, the AOFAS score was 83.30±13.94 (range, 24-100). Ten (38%) of 26 patients had radiographic evidence of posttraumatic ankle arthritis. According to the Kellgren-Lawrence grading scale criteria, there were grade I in 5 cases, II in 2 cases, III in 2 cases, and IV in 1 case. 2 cases of wound dishence were recovered through changing dressing and 2 cases of skin necrosis were recovered by skin graft and flap transposition respectively. There were no significant complications such as infection, nonunion, or implant failure.Conclusion:The transsyndesmotic ankle fracture dislocation, represents an exceptional pattern of high-energy fractures with significant syndesmotic disruption, and potential soft tissue compromise. Careful attention to radiographic findings can identify unique fracture characteristics relative to operative decision-making. Tibialis posterior tendon dislocation, a rare complication in the transsyndesmotic ankle fracture dislocation injuries, can impede anatomical reduction of the ankle mortise. The open reduction and internal fixation may be an optimal approach to treat transsyndesmotic ankle fracture dislocation injuries. However, the rate of posttraumatic arthritis is relatively high.
