Objective To study the effects of extracorporeal shock wave therapy (ESWT) on avascular nec-rosis of the femoral head. Methods Thirty-two rabbits were used to make the avascular necrosis of the femoral headmodel by use of freezing method. Two rabbits were chosen to check the result of the model. Thirty rabbits were ran-domly divided into 2 groups : a treatment group and a control group. Each group was observed 2, 4 and 8 weeks aftertreatment. Morphological and pathological changes of the femoral head were observed. An immunohistochemicalmethod was used to examine the distribution of vessel endothelium growth factor (VEGF) and fibroblast growth factor(bFGF) immunoreactive-positive cells in the bone tissues. Results Morphologically, the femoral heads of treat-ment group were smoother and glossier than those of the control group. The empty lacunae ratio, the number of theosteoblast was significantly different between the treatment and the control group. The expression of VEGF and hFGFin the bone tissues of treatment group increased significantly when compared with control group. Conclusion ES-WT can promote healing of avascular necrosis of femoral head.

Objective To understand the clinical effect of conservative lapamscopic surgery with stripping corpus luteum for fallopian pregnancy to prevent persistent ectopic pregnancy.Methods From January 2005 to Augnst 2008.82 cases of fallopian pregnancy (6 cases for the second time) were performed conservative operatio through laparoscopic surgery with stripping corpus luteum.Seventy one cases underwent salpingostomy to remove the embryo, and other 11 cases were performed with extrusion of embryo sac at ampulla.The level of serum progesterone,β-HCG were measured before and after the therapy.All patients were followed up for one year.Results All patients'surgery had been successfully done through laparoscopie surgery.The duration of stripping corpus luteum was 5 to 10 minutes.The serum β-HCG(Mean±SD:(1213.51±118.84)U/L)and progesterone(Mean±SD:(3.25±2.44)nmol/L)arer operation were significantly lower than before the therapy(Mean±SD:(4267.86±983-56)U/L.(13.71±6.24)nmol/L,respectively)(P<0.01).The decrease of β-HCG value wag significantly correlated with the decreasing of progesterone(r=0.697,P<0.05).Only one patient had a persistent ectopic pregnancy.Fallopian examination through hysterosalpingography after 3 months was unobstructed in 71.1%(32/45 cases)and oh-strueted in 7 cases(15.6%).After one year ofthetherapytwo patients hadectopic pregnancy atthe same fallopian tube.Conclusions For females who have reproductive requirements with experience of fallopian pregnancy,conservative operation through laparoscopic surgery with stripping corpus luteum is safe and effective,and might have an important clinical effect to prevent postoperative persistent ectopic pregnancy.

Since the emergence in 1980s,community-associated methicillin-resistant Staphylococcus Aurues (CA-MRSA) has caught great attention of the researchers and clinical practitioners all over the world. In recent scientific papers,people found that CA-MRSA's capability to adapt itself to the hostile environment and to colonize is a kind of important virulence factor. A newly unveiled gene,designated arginine catabolic mobile element (ACME),in USA300 stains contributes much to this sort of ability. The arginine deiminase encoded by ACME plays an important role in colonization.

OBJECTIVE:To observe therapeutic efficacy and safety of low-molecular-weight-heparin-sodium combined with dy-drogesterone in the treatment of threatened abortion. METHODS:Medical information of 72 patients with threatened abortion were analyzed retrospectively and divided into control group(36 cases)and observation group(36 cases). Control group was given Dy-drogesterone tablet with initial dose of 40 mg,one day later every 12 h 10 mg/time. Observation group was additionally given ab-dominal subcutaneous injection of Low-molecular-weight-heparin-sodium injection 5000 U,once a day,on the basis of control group. Both groups were treated for a week. Clinical efficacies of 2 groups were observed,and lumbar acid,vaginal bleeding,ab-dominal pain time,total treatment time,neonatal birth weight were also observed. The levels of hs-CRP,fibrinogen,D-dimer and platelet,the occurrence of ADR were observed before and after treatment. RESULTS:The total response rate of observation group was significantly higher than that of control group(91.7%vs. 80.6%),the backache,vaginal bleeding,abdominal pain time and to-tal treatment time of observation group were significantly shorter than those of control group,the neonatal birth weight and gesta-tional age of observation group were significantly more than those of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the levels of hs-CRP,fibrinogen,D-dimer and platelet between 2 group(P>0.05);after treatment,the levels of hs-CRP,fibrinogen,D-dimer and platelet in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Based on routine treatment,low-molecu-lar-weight-heparin-sodium combined with dydrogesterone shows good therapeutic efficacy and safety for threatened abortion.
