Purpose:To observe the effect of thalidomide combined with chemotherapy in the treatment of newly diagnosed multiple myeloma. Methods:34 patients were divided into two groups at random. 14 cases in the treated group were initially administered thalidomide at doses ranging from 100mg~200 mg/d,and the dosage was escalated by 100mg~200 mg every two weeks until patients could not tolerate the treatment.The maximal dose did not exceed 600mg/d.MP or M 2 protocol was delivered to those patients in the treated group concomitantly.20 cases in the control group received chemotherapy consisting of MP or M 2 protocol only.Evaluation of 3-months effective(partial remission plus progress)rate,one-year event free survival and two-years overall survival was done in both groups. Results:3-months effective rate is 85.7% in the treated group and 60% in control group.One-year EFS is 71.4% in the treated group while that in the control group is 35%.Two-years OS are 57.1% and 25% respectively.The side effects of thalidomide are tolerable,and constipation is the most common. Conclusions:The combination of thalidomide and chemotherapy is an effective treatment for newly diagnosed MM,and it demonstrates an improvement in effective rate,one-year EFS and two-years OS.

Objective To investigate the effect of penehyclidine (PHCD) pretreatment on Toll-like receptor 4 (TLR4) mRNA expression in the lung following acute lung injury (ALI) induced by hemorrhagic shock in rats. Methods Forty healthy SD rats of both sexes weighing 200-250 g were randomly divided into 5 groups( n = 8 each): group Ⅰ sham operation (group S); group Ⅱ ALI (group ALI); group Ⅲ, Ⅴ, PHCD 0.3,1.0, 3.0 mg/kg were given iv respectively at 30 min before hemorrhagic shock (P1-3). Hemorrhagic shock was induced by exsanguinations. MAP was maintained at 35-45 mm Hg for 60 min. The animals were killed at 4 h after resuscitation. Their lungs were removed for microscopic examination, W/D lung weight ratio and determination of TLR4 mRNA expression in the lung tissue (by RT-PCR). NF-κB p65 protein expression in the lung tissue was determined (by immuno-histochemical staining). Results Hemorrhagic shock significantly increased TLR4 mRNA and NF-κB p65 protein expression in the lung tissue and W/D lung weight ratio. Pretreatment with PHCD 1.0 or 3.0 mg/kg significantly inhibited hemorrhagic shock-induced increase in TLR4 mRNA and NF-κB p65 protein expression in the lung and W/D lung weight ratio. The lung injury was significantly ameliorated in group P2,3 as compared to group ALI. Conclusion PHCD pretreatment can attenuate ALI induced by hemorrhagic shock through down-regulation of TLR4 mRNA expression and decreasing NF-κB activity in the lung.

Objective: To explore the treatment effect of sticking-needle acupuncture plus tendon-regulating manipulation on pain, swelling and joint dysfunction due to acute ankle sprain.Methods: A total of 80 patients with acute ankle sprain were recruited and divided into a control group and a treatment group according to the random number table method, with 40 patients in each group. Both groups received the same conventional interventions. The control group was treated with additional tendon-regulating manipulation, and the treatment group was treated with tendon-regulating manipulation plus sticking-needle acupuncture. The pain, swelling and joint dysfunction of the ankle were observed in both groups before and after 3 d, 7 d and 14 d of treatment. Results: Before treatment, there was no statistically significant difference in the visual analog scale (VAS) score of pain between the two groups (P>0.05). After treatment, the VAS scores of both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the VAS scores in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). Before treatment, there was no statistically significant difference in the degree of swelling between the two groups (P>0.05). After treatment, the degrees of swelling in both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d and 7 d of treatment, the degrees of swelling in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). There was no statistical difference in the degree of swelling between the two groups after 14 d of treatment (P>0.05). Before treatment, there was no statistically significant difference in the American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot scale score between the two groups (P>0.05). After treatment, the AOFAS ankle-hindfoot scale scores of both groups showed an increasing trend over time, and all the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the AOFAS ankle-hindfoot scale scores in the treatment group were higher than those in the control group, with statistically significant differences (P<0.05). Conclusion: Based on the routine intervention, the addition of sticking-needle acupuncture and tendon-regulating manipulation was better in alleviating pain and swelling and improving joint function in patients with acute ankle sprain than the addition of tendon-regulating manipulation alone.

Objective To investigate the effect of combined Metformin and esomeprazole therapy on plasma levels of gastrin,blood glucose,glycosylated hemoglobin(HbA1c) and insulin in elderly patients with type 2 diabetes.Methods A randomized,double-blind,placebo-controlled study of 41 elderly patients with type 2 diabetes was conducted.Patients were randomly assigned into treatment group(combination therapy with Metformin 0.5 g,bid or tid and Esomeprazole 20 mg,qd,for 12 weeks)and placebo group(Metformin monotherapy 0.5 g,bid or tid,for 12 weeks).Fasting blood samples were taken from vein before and after treatment.Fasting serum levels of gastrin,glucose,HbA1c,insulin,lipids,liver and renal functions were compared between the two groups.The homeostasis model of assessment for insulin resistance index(HOMA-IR) and insulin secretion index (HOMA-β)were calculated,and complications were recorded.Results There were no significant differences in body mass index and waist circumference between the two groups.Serum gastrin level was slightly increased in the treatment group 12 weeks after treatment,but without statistically significance [(127.20±9.21)ng/L vs.(131.53±7.84)ng/L,P>0.05],and serum gastrin level had no significant differences in the placebo group before and after treatment [(128.42±4.58)ng/L vs.(127.51±3.47)ng/L,P>0.05].However,there were no significant differences in the changes of blood glucose,HbA1c,insulin,HOMA-β and HOMA-IR before versus after therapy,and between the two group(all P>0.05).Conclusions Combined Metformin and insulin therapy cannot increase serum gastrin and insulin levels and has no significant effect on reducing blood glucose and HbA1c levels in elderly patients with type 2 diabetes.

Objective To study the prenatal genetic diagnostic methods for hemophilia A fetus.Methods From 2002 to 2006,19 hemophilia A families were diagnosed either by long distance-polymerase chain reaction(LD-PCR)for factor Ⅷ intron 22 inversion or by the DNA polymorphism genetic linkage analysis of factorⅧin the Beijing Chaoyang Hospital.Results (1)Totally 19 women,with 22pregnancies received the prenatal diagnosis of fetal hemophilia A.The average week at diagnosis was 23(17-34)weeks.All the direct fetal blood sampling(DFBS)were successful.There was no fetal-loss caused by the procedures.(2)Of the 19 hemophilia A families,14 appeared to be factorⅧintron 22inversion,in which 16 prenatal diagnoses were done,10 fetuses were diagnosed as genetical hemophilia A patients,and 6 fetuses were normal.(3)Using combined polymorphism genetic linkage analysis 6 prenatal diagnoses were done,including one woman's two pregnancies,in which both her fetuses were diagnosed as genetical hemophilia A patients.(4)Factor Ⅷ levels of 16 fetuses were measured,and 6 fetuses were unmeasured either because the pregnancy weeks were lower than 20 weeks or the parents refused.Factor Ⅷlevel ranged from 0 to 198%.There were 11 fetuses whose factor Ⅷ levels were lower than 10%.Ten of them were diagnosed to be genetical hemophilia A patients,and in only one boy the factorⅧlevel was 2%,but the genetic diagnosis was normal and for one year's follow up he was doing normal.Conclusion LDPCR combined with polymorphism genetic linkage analysis enables a quick and correct detection ofhemophilia A carrier.For a carrier pregnancy.prenatal diagnosis could be done for the male fetus.Factor Ⅷ deficiency of the fetus could help make the diagnosis but the final diagnosis should be based on genetic evidence.
