Femurs of 206 Chinese adults (122 males and 84 females) were used for the present study. Their lengths, and torsional and inclinational angles were measured after Martin's method. The results are as follows:1. The Lengths of FemurThe average length of the femur in males is 43.68?2.02 cm. (43.77?2.02 cm. on the left side, and 43.61?2.04 cm. on the right), while that in females is 40.96?2.84 cm. (41.05?2.84 cm. on the left side and 40.93?2.84 cm. on the right). No significant difference has been found between the femoral lengths of both sides; however, there is a significant difference between both sexes.2. The inclinational angles of femoral neckTheir average value in the male is 128.46??6.58?(128.87??6.76?on the left side, and 127.46??6.60? on the right), but that in the female is 130.52??6.44?(130.88??6.10? on the left side, and 130.17??6.80? on the right). No significant difference exists between both sides; however, there is a significant difference between both sexes.3. The Torsional Angles of FemurTheir average value in the male is 11.95??8.89? (14.51??8.08? on the left side, and 9.20??7.75? on the right), whereas that in the female is 12.80??9.07? (15.95??9.63? on the left side, and 9.63??7.31? on the right). There is a significant difference between two sides, but no significant difference between both sexes.4. The relationship between the inclinational and torsional angles on one hand and the changes in the femoral lengths on the other has been studied by dividing the femurs into groups according to their lengths. It has been shown that the changes in the femoral length exert no effect upon the inclinational and torsional angles of the femoral necks, neither in the male nor in the female.Besides, a comparison has also been made between the femurs of both sides and both sexes, between the femoral lengths and the inclinational and torsional angles, and between the variant ranges of the torsional angles of femurs. A discussion on these problems has been made with reference to the racial differences.

Objective To observe the effect of residual tumor after radiotherapy on survival rate of patients with nasopharyngeal carcinoma (NPC). Methods From Jan. 1989 to Dec. 1998, 108 of 304 NPC patients pathologically confirmed, had residual tumor after radical radiotherapy, of whom, 26, 68, 14 had residual lesion in the nasopharyngeal cavity alone, cervical lymph node alone, and nasopharyngeal cavity plus cervical lymph node. Results The overall 1 , 3 , 5 , and 10 year survival rates (OS) significantly decreased in the residual group. The highest OS was in the group with nasopharynx residual alone, and the lowest in nasopharynx plus residual lymph node group. The bigger the residual lesion, the lower the OS. Conclusions The overall survival rate decreases in patients with residual lesion after radiotherapy, especially in patients with both nasophrynx and regional lymph node residual. Tumor residual after radiotherapy can be a prognostic indicator for patients with NPC.

Objective To evaluate the therapeutic efficacy and its related factors of entecavir treatment for patients with acute on chronic hepatitis B liver failure (ACHBLF).Methods One hundred and eight patients with ACHBLF were enrolled and divided into entecavir group (n=53) and control group (n=55).HBV DNA level, liver function and 48-week survival rate were observed, and C ox regression model was established to identify the factors which may affect the efficacy of entecavir treatment.Results Totally 70 patients died in the study and 66 died within 12 weeks.The statistical difference on cumulative survival rate between two groups was observed from the third week on (χ2=5.357, P ＜ 0.05).The 48-weekcumulative survival rate in entecavir group was 47.2% (25/53), while that in the control group was 23.6%(13/55) (χ2=7.432, P ＜ 0.01).In entecavir group, for patients aged ＜ 40 with serum bilirubin level ＜513 μnol/L and international normalized ratio (INR) ＜ 2.5, the fatality rates decreased 74.9%, 75.3%and 76.0%, respectively.Conclusions Entecavir may improve the survival rate of patients with ACHBLF.Age, serum bilirubin level and INR are major factors related to the therapeutic efficacy.

Objective To investigate the change of serum osteoprotegerin level and relationships between serum osteoprotegerin level and coronary heart disease (CHD) in patients with type2 diabetes mellitus (DM) complicated with CHD.Methods One hundred and eight patients with type 2 DM complicated with CHD were selected as DM with CHD group,including 68 cases with acute coronary syndrome and 40 cases with stable angina pectoris.In addition,60 type 2 DM patients without CHD (DM without CHD group) and 40 healthy people (control group) were selected.Serum osteoprotegerin level was measured by enzyme linked immunosorbent assay.Results The serum osteoprotegerin level in DM with CHD group was significantly higher than that in DM without CHD group and control group [(4.12 ± 0.71)ng/L vs.(2.69 ± 0.52) and (2.14 ± 0.37) ng/L],and there were statistical differences (P＜ 0.05 or ＜ 0.01).In DM with CHD group,the serum osteoprotegerin level in acute coronary syndrome was significantly higher than that in stable angina pectoris [(4.56 ±0.92) ng/L vs.(3.61 ±0.76) ng/L],and there was statistical difference (P ＜ 0.05).The serum osteoprotegerin level in patients with Gensini score ＞ 40 scores (41 cases)was significantly higher than that in patients with Gensini score 20-40 scores (53 cases) and patients with Gensini score ＜ 20 scores (14 cases) [(4.92 ± 0.89) ng/L vs.(4.08 ± 0.75) and (3.39 ± 0.85) ng/L],and there were statistical differences (P ＜ 0.01 or ＜ 0.05).The serum osteoprotegerin level in patients with Gensini score 20-40 scores was significantly higher than that in patients with Gensini score ＜ 20 scores,and there was statistical difference (P ＜0.05).The serum osteoprotegerin level in single-vessel lesion (16 cases),double-vessel lesion (57 cases) and three-vessel lesion (35 cases) [(3.52 ± 0.82),(4.54 ± 0.68),(4.75 ±0.93) ng/L] were significantly higher than those in control group,and there were statistical differences (P ＜ 0.05); and the serum osteoprotegerin level in double-vessel lesion and three-vessel lesion were significantly higher than those in single-vessel lesion,and there were statistical differences (P ＜ 0.05) ;there was no statistical difference between three-vessel lesion and double-vessel lesion(P＞ 0.05).The results of Logistic regression analysis showed that glycosylated hemoglobin,total cholesterol,high sensitivity C reactive protein and osteoprotegerin were independent risk factors of type 2 DM complicated with CHD.Conclusions Serum osteoprotegerin level in patients with type 2 DM complicated with CHD is significantly increased.There is a significant association between serum osteoprotegerin level and the presence and severity of CHD,and the serum osteoprotegerin level is independent risk factors of type 2 DM complicated with CHD.

Objective To investigate the balance of Th1/Th2 cytokines and its relationship with prognosis of severe chronic hepatitis B ( CHB ). Methods Peripheral blood samples were collected from 112 severe CHB patients, 30 CHB patients and 30 healthy controls. IL-4, IFN-γ levels and HBV DNA loads were measured by ELISA and fluorescent PCR, respectively. The levels of cytokines in different stages, and their correlations with HBV DNA loads and short-term prognosis were analyzed. Results Higher levels of IL-4, IFN-γ and Th1/Th2 ratios in peripheral blood were detected in patients with severe CHB than those with CHB and the healthy controls (Z = 8.968, 10. 004 and 26. 067, P =0. 009, 0. 007 and 0. 000). IL4 levels in patients with end-stage server CHB were markedly higher than those in other stages ( Z = 3. 672 and 3. 158, P= 0.000 and 0.002), while their Thl/Th2 ratios were lower (Z=3. 161 and 2. 166, P=0.002 and 0. 030). No significant differences on levels of IL-4, IFN-γ and Th1/Th2 ratios were observed in severe CHB patients with different HBV DNA levels (Z =4.431, 2.626 and 0. 140, P =0.219, 0.403 and 0. 987). Elevated IL-4 was closely correlated with the high case-fatality rate within 12 weeks. Conclusions The balance between Th1 and Th2 cytokines is- disturbed in patients with severe CHB. Thl/Th2 ratio decreases with the aggravation of diseases, which may indicate unfavorable short-term prognosis.
