OBJECTIVE: To study the etiological factors of knee osteoarthritis and to provide the anatomical basis of corrective therapy for knee joint deformity by comparing the biomechanical differences of the knee joints between the osteoarthritis patients and the normal people. METHODS: The sexes, ages, heights, weights, painful characters and accompanied symptoms were recorded, and the femoral angle, tibial angle, femorotibial angle, joint space angle, and the height and width of condylus medialis and lateralis were measured for 29 selected knee osteoarthritis patients. And the biomechanical data of the patients were compared with those of the 19 normal people. RESULTS: The femoral angle of the osteoarthritis patients was smaller and the joint space angle was greater statistically than that of the normal people, and the ratios of height and width of condylus medialis and condylus lateralis of the osteoarthritis patients were greater than those of the normal people. CONCLUSION: In the patients, the gravity line of the lower limb inclines to the condylus medialis, so the condylus medialis is more vulnerable. And the configuration of the condylus of the patients, which is narrower and longer, is different from that of the normal people. It may be one of the etiological factors of knee osteoarthritis.

Objective To detect the expressions of nerve growth factor (NGF) and its receptors tyrosine kinase A (TrkA) as well as p75 neurotrophin receptor (p75NTR) in the lesions of lichen planus.Methods Biopsy specimens were collected from the lesions of 32 patients with lichen planus and normal skin of 12 healthy human controls and subjected to paraffin embedding.Immunohistochemical avidin-biotin complex (ABC) method was used to detect the expressions of NGF,TrkA and p75NTR.Results NGF and TrkA,which were located in the cytoplasm of keratinocytes,were strongly or moderately expressed in the lesional skin specimens,but absent or weakly expressed in the normal skin specimens (both P ＜ 0.01).No significant differences were observed in the expression of p75NTR between the lesional and normal skin specimens,or in the expressions of NGF,TrkA or p75NTR among specimens from patients in different age groups,patients of different gender or lesions at different sites (all P ＞ 0.05).There was a positive correlation between the expression of NGF and TrkA in the lesions of lichen planus (R2 =0.535,P ＜ 0.01).Conclusion NGF may play a certain role in the development of lichen planus via its highaffinity receptor TrkA.

OBJECTIVE: To explore a simple speedy specific and sensitive method to detect specific IgM (sIgM) and IgG (sIgG) antibodies of hemorrhagic fever with renal syndrome (HFRS),and to study the therapeutic effects of integrated traditional Chinese and western medicine on HFRS. METHODS: The serum of 559 patients with HFRS were tested with colloidal gold immuno-dot assay (CGIDA) for sIgM and sIgG antibodies and compared with enzyme linked immunosorbent assay (ELISA) or indirect fluorescent antibody test (IFAT). One hundred and one patients with HFRS were randomized into treatment group (n=50),treated with Kuhuang Injection, Shenmai Injection and Huangqi Liquid) and control group (n=51),treated with Ribarvirin and Ganlixin Injection). RESULTS: The positive rate of sIgM detected with CGIDA was 70.8% and the positive rate of sIgG detected with CGIDA was 87.5%. The days for fever decline, symptoms alleviation and sign relief between the treatment group and control group were similar (P>0.05). The days for recovery of kidney function in the control group was less than that in the treatment group (P<0.01). The rate of crossing shock stage in the treatment group was higher than that of the control group (P<0.01). CONCLUSION: CGIDA was more simple, speedy, specific and sensitive than ELISA or IFAT in detecting the sIgM or sIgG antibodies in serum of patients with HFRS. Although the sensitivity of CGIDA was lower than that of ELISA the CGIDA had no false positive reaction the sensitivity of CGIDA was higher than that of IFAT on detecting IgG. The effect of the treatment group was similar to that of the control group. But the crossing shock stage rate in the treatment group was higher than that of the control group while the control group was better than the treatment group in recovering the kidney function.
