0.05) except for the positive reaction in the smooth muscle cells of the small vascular walls. While in the symptomatic group, significant expression of ?-SMA was observed besides the expression in the smooth muscle cells of the small blood vessels, and the positive fields were mainly located in the cellular plasm. The positive fields were diffusely distributed between the proliferous nerve fibers and collagen tissues most of which showed the streak or linear shapes together with some dot like expression figures. The difference of the expression level among the three groups was significant(F=289.534, P0.05). Correlation analysis indicated that the expression level of ?-SMA was positively correlated with the scale of the pain assessed by means of a 10 point visual analogue scale (VAS)(rs =0.980,P

Objective To investigate the effects of total hip replacement (THR) and dynamic hip screw (DHS) to intertrochanteric fracture in the geriatric with serious osteoporosis. Methods The clinical data of 51 senile cases (age over 60 years) with serious osteoporosis (Singh index less than grade Ⅲ ) cured from January 2003 to March 2008 were retrospectively reviewed. Two different groups were randomly selected from all cases treated with THR and DHS. Nineteen cases of THR were selected in THR group, modified Gibson approach was taken to complete hip joint replacement Thirty-two cases of DHS were selected in DHS group,lateral hip approach was employed to complete DHS fixation. Mobilization by CPM from the 2nd day and weight burdening from 3rd to 7th day according to general physical condition after surgery were carried out in THR group, mobilization and weight bearing start according to different conditions from the 2nd to 10th week in DHS group. Results Among 51 cases, 47 cases had got follow-up for 5.0 -40.5 (28.1 ± 11.9) months. Nineteen cases in THR group had got follow-up, Harris hip score of 18 cases (94.7% ) were good or excellent, and the other 1 case was bad. Twenty-eight cases in DHS group had got follow-up. Harris hip score of 23 cases (82.1% ) were good or excellent, and the other 5 cases were bad. There was statistical significance between the two groups (P < 0.05 ) . The average periods to start partly weight bearing of THR group and DHS group were( 8.3 ±4.2) days and (43.6 ± 15.3) days respectively, there was statistical significance between the two groups (P< 0.05). Conclusion To the geriatric intertrochanteric fracture with serious osteoporosis, THR is a better choice than DHS, because THR has shorter recovery period before full weight bearing, higher hip functional outcome evaluated by Harris hip score, earlier recovery of mobilization and less complications related with long term bed-bound .

The nutritional status, serum protein, albumin, calcium, zinc, iron, SF, FEP, vitamin A, activity of RBC transketolase, and blood glutathione redu-ctase of 349 normal primigravidas, 30 healthy non-pregnant women and 42 toxemic gravidas were estimated longitudinally from the 1st trimester to delivery. It was noted that serum protein, albumin, Ca, Zn, and Fe decreased markedly in the course of pregnancy. The content of serum vitamin A showed no variation or decrease in the 3rd trimester in 1/3 of the pregnant women observed. Insufficiency of thiamine and riboflavin were noted in 16.7% and 47% of the normal pregnant women respectively. The adequate nutrients intakes in pregnancy were considered to be: Energy, +200 kcal/d; Protein, + 15g/d in the 2nd trimester and +25g/d in the 3rd trimester; Calcium 1000 mg/d in the 2nd trimester and 1500mg/d in the 3rd trimester; Zinc, 20mg/d; Iron 26 or 30 mg/d by supplementation if possible; vitaminA 1000 ?gRE/d; both thiamine and riboflavin 1.8 mg/d.
