1.Advances on biomechanics and kinematics of sprain of ankle joint.
China Journal of Orthopaedics and Traumatology 2015;28(4):374-377
Ankle sprains are orthopedic clinical common disease, accounting for joint ligament sprain of the first place. If treatment is not timely or appropriate, the joint pain and instability maybe develop, and even bone arthritis maybe develop. The mechanism of injury of ankle joint, anatomical basis has been fully study at present, and the diagnostic problem is very clear. Along with the development of science and technology, biological modeling and three-dimensional finite element, three-dimensional motion capture system,digital technology study, electromyographic signal study were used for the basic research of sprain of ankle. Biomechanical and kinematic study of ankle sprain has received adequate attention, combined with the mechanism research of ankle sprain,and to explore the the biomechanics and kinematics research progress of the sprain of ankle joint.

4.Effects of strontium on proliferation and osteogenic differentiation of human bone marrow mesenchymal stem cells in vitro
Medical Journal of Chinese People's Liberation Army 1981;0(04):-
Objective To study the effects of strontium (Sr) on proliferation and osteogenic differentiation of human marrow mesenchymal stem cells (hMSCs) in vitro,and to determine its optimal concentration.Methods Six milliliter of bone marrow was obtained from a healthy adult volunteer,the hMSCs were then isolated and cultured in vitro,and the cell phenotype was identified by flow cytometry.The 4th passage cells were used for experiment,and they were randomly divided into 5 groups:the osteogenic agents (10-8mol/L dexamethasone,50?g/ml ascorbic acid and 10mmol/L beta-sodium glycerophosphate) were used alone in the control group (group A),and the combination of osteogenic agents and different doses of strontium chloride (3.75?10-3,3.75?10-2,3.75?10-1 and 3.75mmol/L) were used in group B,C,D and E.The proliferation level,alkaline phosphatase (ALP) activity and osteocalcin (OCN) content of MSCs were determined by MTT colorimetric assay,enzyme-labeled method and radioimmunological method,respectively.The amount and area of calcium nodules in each group were observed by alizarin red staining.Results The proliferation and osteogenic differentiation rate of each group increased significantly with the lapse of culture time(P
5.The analysis for images of multi-slice spiral CTE performance levels in active ulcerative ;colitis
China Medical Equipment 2016;13(9):67-69,70
Objective: To investigate the imaging characteristics of the intestinal multi-slice spiral CT enterography (CTE) in active ulcerative colitis(UC), analyze and summarize its application value. Methods: A total 43 cases diagnosed with active UC from April 2014 to April 2015 in our hospital were selected and divided into mild, moderate and severe three levels with each level as a group, treated by multi-slice spiral CTE examination system based on the improved Mayo system, comparing different performances of CTE levels. Results:43 cases of UC patients participating in the study, eight patients were mild, 16 cases were moderate and 19 cases were severe. There was statistically different in the intestinal mucosa in the presence of air bubbles between the mild and moderate group (x2=21.62; P<0.05). There were statistical differences between moderate group and severe group in the case of colon bags disappearing, as well as the lymph nodes of the intestinal wall layering (x2=25.95, x2=17.46, x2=19.46;P<0.05). At the same time, the differences of three groups of patients were not statistically significant on an increase in mesenteric vascular (P<0.05), the degree of enhancement in the intestinal mucosa, intestinal wall thickening, perirectal fat deposition, luminal stenosis and other projects (F=0.36, F=1.58, F=0.31;P>0.05). Conclusion:UC patients CTE examination, which can effectively conduct a comprehensive assessment against bowel, intestinal and parenteral, provide favorable conditions for the activity of UC clinical diagnosis and classification.
6.Moderating effects of gender on relationship between love relationship satisfaction and empathy in college students
Chinese Mental Health Journal 2017;31(7):573-576
Objective:To explore the moderating effect of gender between love relationship satisfaction and empathy in college students.Methods:Totally 175 pairs of college couples were enrolled.They were assessed with the Quality of Relationship Index (QRI) and Interpersonal Reactivity Index-C (IRI-C) to evaluate love relationship satisfaction and empathy.IRI-C included 4 dimensions named perspective taking (PT),personal distress (PD),fantasy (FS) and empathetic concern (EC).Multiple regression analysis was used to investigate the moderating effects of gender on relationship between love relationship satisfaction and empathy in college students.Results:The scores of QRI and PT were higher in the males than in the females,but the PD scores were lower in the males [(36.6 ±5.9) vs.(35.2 ±6.0),(10.9 ±3.4) vs.(9.9 ± 3.4),(6.0 ±4.1) vs.(8.1 ±4.3),Ps <0.01].The QRI scores were the lowest in the students who were in love for less than 3 months (33.1 ±7.1).The PT scores positively predicted the QRI scores (3 =-0.19),the PD scores multiplied by gender negatively predicted the QRI scores (β =-0.17),and the EC scores multiplied by gender positively predicted the QRI scores (β =-0.21).Conclusion:Male students may experience higher love relationship satisfaction than females.The gender plays a moderating role to the influence of empathy on love relationship satisfaction in college students.
7.Substitute popliteal vein valve operation for primary deep vein insufficiency of lower limbs
Chinese Journal of General Surgery 1997;0(06):-
Objective To investigate the clinical value of substitute popliteal vein valve operation (SPVSO) for primary lower limb deep vein insufficiency(DVIS). Methods The clinical data of 859 cases(907 legs) of DVIS who underwent SPVSO in the past 10 years in our hospital were analyzed retrospectively. Results Symptoms of edema and fatigue distinctly reduced or disappeared after the operation.Pigmentation in the lower portion of the leg began to disappear in 1 week, and nearly or totally disappeared within 2 weeks after the operation.Ulcer in the lower portion of the leg recovered three weeks after the operation. Patients were followed up for 6 to 120 months. The effective rate within 60 months was 96.8%, and the effective rate over 60 months was 87.2%. Conclusions The curative effect of SPVSO on primary deep vein insufficiency of lower extremity is definite and it is worthy to be clinical practice.

9.Several points in therapy of uveitis
Ophthalmology in China 1993;0(03):-
Therapies for uveitis include drug treatment and surgery.Medical therapies including proper administration of corticos- teroids,immunosuppressive drugs,nonsteroidal anti-inflammtion drugs and anti-infective drugs are important in management of the in- traocular inflammation and decreasing the risk of complications,furthermore,are the basis for surgical treatment of uveitis.
10.Inhibitory effect of 5-aminolevulinic acid photodynamic therapy on human papillomavirus replication in condyloma acuminatum lesions
Chinese Journal of Dermatology 2014;47(10):739-741
Objective To detect the changes in DNA loads of human papillomavirus (HPV) type 6/11 in lesions of patients with condyloma accuminatum (CA) before and after 5-aminolevulinic acid photodynamic therapy (ALA-PDT).Methods After removal of warts by electrocautery,HPV6/11-positive patients with CA were divided into two groups:treatment group (32 cases) receiving two sessions of ALA-PDT with intervals of 7-10 days,and control group (29 cases) remaining untreated.Exfoliated cells were collected from the lesional sites of these patients before and 3 months after the first session of ALA-PDT,and fluorescence-based quantitative PCR was conducted to estimate the DNA loads of HPV 6/11 in these cells.Results Three months after the first session of ALA-PDT,89.7% (26/29) of the patients in the treatment group and 68.4% (13/19) in the control group became HPV DNA negative,with significant differences between the treatment group and control group in the DNA loads of HPV ((1.70 ± 7.86) × 105 vs.(1.27 ± 2.21) × 106 copies/ml,P < 0.05).Conclusion ALA-PDT can reduce HPV DNA loads in lesions of CA in patients.
