Objective To apply a hand function laserimager to evaluate the effect of acupuncture on hand dysfunction after stroke. Meth-ods From January to June, 2016, 18 stroke patients with upper limb dysfunction were divided into control group (n=9) and acupuncture group (n=9). The control group received routine medication and rehabilitation, while the acupuncture group received acupuncture in addi-tion. They were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) of upper limb motor function and modified Bathel Index (MBI) before and after three-week treatment, while the region of interest (ROI) of their hands was tested with the hand func-tion laserimager. Results The scores of MAS and FMA improved after treatment in both groups (t>4.44, P<0.01), and improved in the score of MBI in the acupuncture group (t=3.95, P<0.01). The scores of MAS, FMA, and MBI improved more in the acupuncture group than in the control group (t>3.17, P<0.01). Meanwhile, the scores of ROI decreased in the affected hands after treatment (t>7.78, P<0.001), and de-creased more in the acupuncture group than in the control group (t=-2.23, P<0.05). No significant difference was observed in the scores of ROI of the unaffected hands (t=-0.11, P>0.05) between groups. Conclusion The hand function laserimager, which responds to the blood perfusion of the hand, can be used as a tool to evaluate the hand function.

Objective:
To explore the factors affecting the prevalence of HIV-associated neurocognitive disorders (HAND) among HIV/AIDS patients, so as to provide insights into developing HAND prevention measures.
Methods:
HIV/AIDS patients aged 18 years and above in the Infection Department of Nanjing Second Hospital were selected.Demographic data, treatment regimen and blood biochemical indicators were collected. Depression was evaluated using Patient Health Questionnaire Depression Scale, frailty was evaluated using Chinese version of Tilburg Frailty Indicator, and HAND was evaluated by Montreal Cognitive Assessment Scale. Factors affecting HAND were analyzed using a multivariable logistic regression model.
Results:
Totally 440 questionnaires were allocated and 426 valid questionnaires were recovered, with an effective rate of 96.82%. The median age of patients investigated was 33.00 (interquartile range, 10.00) year. There were 407 males, accounting for 95.54%; 232 patients with bachelor degree or above, accounting for 54.46%; 171 patients with HAND, accounting for 40.14%. Multivariable logistic regression analysis showed that educational level (bachelor degree or above, OR=0.291, 95%CI: 0.157-0.541), depression (OR=2.499, 95%CI: 1.530-4.083), frailty (OR=2.121, 95%CI: 1.307-3.441) and treatment regimen including efavirenz (OR=2.223, 95%CI: 1.367-3.615) were the influencing factors for HAND among HIV/AIDS patients.
Conclusion
Educational level, depression, frailty and use of efavirenz may be associated with HAND risk.

BACKGROUND : After femoral neck fracture, incidences of ischemic necrosis and bone non-healing are closely related to biomechanical characteristics of internal fixation devices. Compression stress can improve fracture healing, tension force can delay fracture healing, and shear stress can inhibit fracture healing. How to relieve shear stress and expand compression stress is of significance for theories and clinical applications.OBJECTIVE: To compare the biomechanical characteristics of the two geometric configurations of three cannulated compression screws in the fixation for femoral neck fracture and to provide a theoretical foundation in the treatment of femoral neck fracture.DESIGN : Observational contrast study.SETTING: Department of Orthopaedics, the 251 Hospital of Chinese PLA; Department of Orthopaedics, the Third Hospital, Hebei Medical University.PARTICIPANTS: The experiment was carried out in the Hebei Orthopaedic Institute from November 2002 to March 2003. Five cadavers including 4 males and 1 female with similar bone mineral density (BMD) were provided by Department of Anatomy, Hebei Medical University. X-ray photographs proved that all the cadavers did not have rheumatism, tuberculosis, tumor, fracture or deformity.METHODS: Ten femurs were randomly divided into inverted and upright isosceles triangle with 5 in each group. Femur samples with femoral neck fracture were fixed with three cannulated screws and measured with the biomechanical machine (CSS-44020, made in Changchun Experimental Researching Institute, provided by Hebei Orthopaedics Institute). The compression strength, torsibility and the maximal vertical loading were compared between the two configurations of screws.MAIN OUTCOME MEASURES:①Displacement of femoral head at 600 N and 750 N during torsibility test; ②torque-moment at 2°and 4°during torsibility test;③load during maximal vertical loading test.CONCLUSION: The effect of three cannulated compression screws configured as an inverted isosceles triangle on the treatment of femoral neck fracture is superior to that of three cannulated compression screws as an upright isosceles triangle.

BACKGROUND: Previously, more researches are about the pathological changesinskeleton, nerveandmuscularofcongenitalclubfoot(CCF). Researches are exploring the changes in the surrounding soft tissues of the deformed feet.OBJECTIVE: To investigate the relationships between the pathogeny,pathology and pathogenesis of CCF and extracellular matrix (ECM).DESIGN: A completely randomized controlled trial.SETTING: Institute of Orthopeadics of the Fourth Military Medical University.PARTICIPANTS: The study was conducted in the Institute of Orthopeadics of the Fourth Military Medical University from November 1997 to August 2003. The deep fascia of study group was obtained from 15 CCF patients who received operative corrections including 11 males and 4 females with an average of 9 months. Five infant corpses who died from non-neural muscular diseases and non-collagen diseases aged between 4 and 21 months with an average age of 11 months were selected in the control group.METHODS: Immunohistochemical investigation was used for the assay of both study and control group. Slices were quantitatively analyzed by Letica Q,570c color image analysis and management system.MAIN OUTCOME MEASURES: Positive expressions of collagen Ⅰ, Ⅱ and Ⅲ, and the relative contents in the deep fascia of both groups.RESULTS: The grey values for relative contents of collagen Ⅰ, Ⅱ and Ⅲ in the interior foot were 116. 43 ± 11. 80, 132. 91 ± 8. 88, and 184. 40 ± 11.82respectively in the study group, and 169.28 ± 8.17, 176. 33 ± 9.47, and 194. 38 ±5.87 in the control group. The contents of collagen Ⅰ, Ⅱ and Ⅲincreased in the contractured tissues of CCF group with the most significant increase in collagen Ⅰ, followed by collagen Ⅲ and the increase of collagen Ⅱwas least. Additionally, collagen Ⅰ was negatively correlated with collagen Ⅲ. The positive expression of collagen Ⅱ might be an accompanying phenomenon, which had no correlation with collagen Ⅰ and Ⅲ.CONCLUSION: ECM changes in CCF are accorded with fibrosis in tissues and organs and general fibroelastosis. Therefore, CCF might be caused by the fibrosis of interior foot.
