Objective To get a controllable acetabulum component inclination angle during the total hip arthroplasty(THA) with the lateral position,a new method using a self-made instrument was introduced.Methods Totally 80 consecutive patients undergoing THA at the lateral position were enrolled.Forty acetabular components were assembled using a new method with a self-made instrument referring to the 42 degrees' angle drawn on the wall(group A),while another 40 acetabular cups were implanted free-handedly(group B).The postoperative inclination angle was evaluated on the anterior-posterior pelvic radiographs.Results The average inclination angle was 43.3° ± 3.7°(34.7°～49.1°) in group A and 40.3 ± 4.5o(32.8°～50.7°) in group B.Moreover,40/40 of group A and 38/40 of group B were in the Lewinnek's inclination safe zone(P＞0.05),without significant differences between the two groups.Conclusion It is practical and reliable to decide the acetabular component orientation using the lateral position instrument and reference angle on the wall.

Objective: To investigate the prevalence and risk factors of diabetic peripheral neuropathy in type 2 diabetic patients under community management programs. Methods: A cross-sectional study was conducted on T2DM patients in eight communities in Wuhan and Changshu cities. Data would included questionnaire, body measurement, blood testing and clinical examination. The criterion of diabetic peripheral neuropathy was under the combination of symptoms with five physical examinations. Binary logistic regression model was used to analyze the influential factors. Results: The overall prevalence of peripheral neuropathy was 71.2% among the diabetic patients who were managed in primary care health services in the two cities. The binary logistic regression method identified older age (≥60 years, OR=2.39, 95%CI:1.95-2.94), longer diabetic duration (≥10 years, OR=1.25, 95%CI: 1.02-1.54), and worse postprandial glucose control (2 h postprandial plasma glucose >10.0 mmol/L: OR=1.65, 95%CI:1.33-2.04) (all P<0.05) as risk factors for the presence of diabetic peripheral neuropathy, while higher education level was protective factor (compared to patients with education levels of primary school or below, OR=0.52, 95%CI: 0.41-0.66; OR=0.59, 95%CI: 0.44-0.79; OR=0.64, 95%CI: 0.44-0.94 for those with education levels of junior high school, senior high school, and college, respectively). Conclusions High rates of diabetic peripheral neuropathy among T2DM patients suggested the urgent need for early screening and standardized management at the community levels. It is necessary to promote appropriate screening techniques and methods to identify the peripheral neuropathy, in the primary health service institutions.

ObjectiveTo study the effect of upper limb robot-assisted therapy on upper limb function and cerebral cortex activation in stroke patients using functional near-infrared spectroscopy (fNIRS). MethodsFrom January, 2022 to January, 2023, 32 stroke patients in Zhejiang Rehabilitation Medical Center were randomly divided into control group (n = 16) and experimental group (n = 16). Both groups received routine neurological medication and routine rehabilitation. The control group received routine upper limb exercises, the experimental group received upper limb robot-assisted therapy. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and fNIRS (oxyhemoglobin, deoxyhemoglobin, and total hemoglobin) before and four weeks after treatment. NIRS_SPM was used for activation analysis, Homer2 was used for blood oxygen concentration analysis. ResultsAfter treatment, the score of FMA-UE increased in both groups (|t| > 5.910, P < 0.001), and was higher in the experimental group than in the control group (t = -2.348, P < 0.05). fNIRS activation results showed that, the activation increased in the experimental group after treatment in channel 17 (F = 9.354, P < 0.01), and it was more than that in the control group (F = 5.217, P < 0.05). fNIRS blood oxygen concentration results showed that, the blood oxygen concentration increased in the experimental group after treatment in channel 17 (F = 12.179, P < 0.01), and it was more than that in the control group (F = 4.883, P < 0.05). ConclusionThe upper limb robot-assisted therapy can improve the upper limb motor function and cerebral cortex activation of stroke patients.
