BACKGROUND: Alendronate has been recently used for treating osteoporosis by inhibiting the activity of osteoclasts, but further clinical observation is necessary to compare its therapeutic effect with exclusive use of calcium supplement.OBJECTIVE: To observe the therapeutic effect of oral alendronate (tianke tablet) on the clinical symptoms and bone mineral density (BMD) of middle-aged and elderly patients for comparison with calcium gluconate.DESIGN: A self-controlled study and controlled trial with concurrent patients.SETTING: Department of Orthopedics, Shenzhen Hospital, Peking UniversityPARTICIPANTS: Sixty-eight middle-aged and elderly patients with osteoporosis were admitted in the Department of Orthopedics, Shenzhen Hospital of Peking University between July 1999 and July 2000. From these patients 62 at the age over 45 years without secondary osteoporosis were selected for this study, who were randomly divided into oral alendronate group (n=32) and oral calcium gluconate group (n=30).INTERVENTIONS: On the basis of comprehensive therapies, the patients in the alendronate group were given 10 mg alendronate daily and those in calcium gluconate group had 20 mL oral calcium gluconate solution (containing 100 mg calcium gluconate, equivalent to 9 mg calcium in every 10 mL) three times daily for three months. According to bodily pain relief, occurrence of new fracture and improvement in BMD, the therapeutic effect was assessed in three grades.RESULTS: Thirty patients in the alendronate group and 26 in the calcium gluconate group completed the study. Alendronate treatment for 3months significantly increased BMD of the patients [(0.716±0.082) g/cm2in comparison with that before treatment [(0.667±0.083) g/cm2, t= 2.473,P ＜ 0.01], whereas the BMD underwent no obvious changes after treatment with calcium gluconate [(0.671±0.081) g/cm2 before vs (0.680±0.073) g/cm2after treatment, t=1.812, P ＞ 0.05]. Significant difference in BMD after treatment was noted between the two groups (t=2.384, P ＜ 0.01). The effective rate was significantly higher in alendronate group than in calcium gluconate group (X2=14.9, P=0.005), but 7 patients complained of abdominal discomfort in the former group and the patients in calcium gluconate group reported no adverse effects.CONCLUSION: Alendronate can inhibit bone absorption, promote the recovery of bone matrix, and increase the bone mass, producing better effect than exclusive use of calcium gluconate oral solution in treatment of the osteoporosis in the middle-aged and the elderly.

Objective To observe the effects of dexmedetomidine on the perioperative stress response and immunologic function in hepatectomy patients with hepatitis cirrhosis.Methods Forty patients(Child-Pugh A or B),ASA Ⅱ or Ⅲ with hepatitis cirrhosis undergoing hepatectomy were randomly divided into dexmedetomidine group(group D)and control group(group C)with 20 cases in each.Patients in group D were administered 0.5 μg/kg bolus dose of dexmedetomidine over 10 min, followed by 0.4 μg·kg-1 ·h-1 infusion until closing abdomen.And patients in group C were given normal saline by the same way as in group D.Flow cytometry was used to detect peripheral blood T lymphocytes (CD3 + ,CD4 + ,CD8 + ,CD4 +/CD8 + ),NK cells at 30 min before anesthesia(T0 ),imme-diately(T1 ),24 h(T2 )and 48 h(T3 )after surgery.Enzyme-linked immunosorbent assay was used to detect the levels of inflammatory cytokines concentration(IL-2,IL-10)at T0-T3 and stress hormones (Cor,ACTH,ALD)at T0 ,T2 and T3 .The levels of SBP,DBP and CVP at T0 ,immediately with intu-bation(Ta ),T1 and extubation(Tb ).Results Compared to those at T0 ,the levels of CD3 + ,CD4 + , CD8 + ,CD4 +/CD8 + at T1 and T2 were significantly lower in both groups(P <0.05),and the levels in group D were obviously higher than those in group C(P <0.05).The levels in group D were back to preoperative levels at T3 ,but the levels in group C were still lower than those at T0 (P <0.05).The levels of NK cells were higher at T1 in both groups,and the levels in group D was significantly higher than those in group C(P <0.05).Compared to those at group D,the concentration of IL-2 was lower at T1 and T2 ,the concentration of IL-10 was higher at T2 and T3 in group C (P <0.05).The levels of Cor,ALD,ACTH at T2 and T3 were significantly higher than those at T0 in both groups,but those in group D were markedly lower than those in group C (P < 0.05 ).The SBP,DBP and CVP of two groups was no statistically significant difference at T0 ,and SBP,DBP and CVP of the group D at Ta , T1 ,Tb was lower than that of T0 and group C (P <0.05).Conclusion Patients with hepatitis cirrho-sis underwent general anesthesia has certain immune suppression after liver cancer surgery,and con-tinuous intravenous infusion of dexmedetomidine during anesthesia may suppress the perioperative stress reaction effectively and alleviate the inhibition of immunologic function.

Histopathological and ultrastructural changes of the lungs were observed in various intervals after high-velocity bullet wounds of the two thighs of dogs. It was found that histologically there were microvascular dilatation, congestion, capillary rupture, interstitial and alveolar bleeding, focal atelecta-sis and pulmonary emphysema in the first half hour and the 6th hour after injury. In addition, microvascular embolism and hyaline membrane formation were seen in the 24th and 72nd hour after injury. Under electron microscopy, there were swelling of capillary endothelium, swelling, degeneration and necrosis of type I pneumocytes, shortening and decreasing of the microvilli of type II pneu-mocytes, significant vacuolation of the lamonar bodies, accumulation of leucocytes and platelets in the capillary lumen,and obvious decrease of the granules in the leucocytes. The mechanism of the pulmonary injury accompanying bullet wound of the thighs was discussed.
