Objective To study the effects of an extended-interval dosing regimen of gonadotropin releasing hormone agonist(GnRH-a) in the treatment of adenomyosis. Methods 20 patients with adenomyosis who asked for medicine treatment were divided into two groups randomly(n=10). The patients in the study group were given four doses of triptorelin depot 3. 75mg every 6 weeks in a new extended-interval dosing regimen. The other patients in the control group were given triptorelin 3.75mg in the conventional depot regimen of six doses,each given 4 weeks apart. The changes of degree of dysmenorrhea and the uterine volume were investigated. And the level of sexual hormone was also detected both before and after therapy.Results After six months of therapy,the reliving rate of dysmenorrheal was 100% both in the new regimen and the conventional regimen. The uterine volume was reduced at 46.7 % and 47. 5 % . And the level of LH, FSH and E2 were decreased significantly(P 0.05).Conclusion The use of the extended-interval dosing regimen of triptorelin depot in adenomyosis results in a consistent hypoestrogenised state,which is similar to that achieved by the conventional regimen. The new regimen thus reduces the cost of treatment obviously.

Objective To investigate effect of first, second, and third trimester placental factors (PF) on CD4, CCR5, and CXCR4 expression in human peripheral blood lymphocytes (PBLs), and to explore their influence on human immunodeficiency virus (HIV) vertical transmission.Methods Human peripheral blood mononuclear cells (PBMCs) were treated with first, second,and third trimester PF (concentration 25%) respectively for 24 hours. The expression of CD4, CCR5,and CXCR4 in PBLs, and the percentages of CCR5+, CXCR4+,and CCR5+CXCR4+ cells in peripheral blood CD4+ lymphocytes were determined with flow cytometry.Results All trimester PFs reduced CCR5 expression in PBLs. The efficiency of the first trimester PF was higher than that of the second and third trimester PF. The percentage of CCR5+ cells in peripheral blood CD4+ lymphocytes of PF groups was significantly lower than that of the control group, and the percentage of CCR5+ cells in peripheral blood CD4+ lymphocytes of the first trimester PF group was significantly lower than that of the second and third trimester group. The percentages of CCR5+CXCR4+ cells in peripheral blood CD4+ lymphocytes of PF groups were significantly decreased as compared with the control group, and the percentage of CCR5+CXCR4+ cells in peripheral blood CD4+ lymphocytes of the first trimester PF group was significantly lower than that of the third trimester PF group.Conclusion PF can reduce the expression of CCR5 in human PBLs and peripheral blood CD4+ lymphocytes, indicating that PF might reduce R5 virus infection via preventing HIV entry, and might play an important role in reducing R5 virus intrauterine infection.

Objective To investigate the effect of external fixator on repairing the vascular injuries in the knee and calf.Methods From May 2004 to October 2010,208 patients (234 sides) with vascular injuries in knee and calf,treated with external fixation,were retrospectively analyzed,including 192 males (217 sides) and 16 females (17 sides) with an average age of 39.6 years (range,14-67).Blood vessel damage:the popliteal artery injury in 84 patients (86 sides),the anterior tibial artery injury in 36 (46),the posterior tibial artery injury in 41(49),the anterior tibial artery and the posterior tibial artery injury in 47 (53).Complete ischemic of the injured distal limb existed in 129 patients(141 sides),incomplete ischemia in 79 patiets (93 sides).All patients underwent emergency surgery.The AO external fixators were used in 164 patients,the chuangsheng inlaid external fixators in 37,and the hybrid external fixators in 7.The injured vessels were anastomosed directly,or indirectly with great saphenous vein.The wounds were treated with phase Ⅰ bandage,skin grafts,flap transplantation or VSD suction.Results One hundred and ninty four patients obtained successful limb salvage; but 14 patients underwent amputation owing to serious damage of limb and poor general condition.One hundred and twenty seven patients underwent the second stage debridement combined with skin graft or flap transplantation; 24 patients underwent the first stage free skin graft or flap transplantation;wound cicatrized by oneself in 43 patients.One hundred and forty eight patients were followed up for 8 months to 3 years.External fixators were removed after an average of 7.2 months (range,1-18).The average healing time of fracture in 102 patients was 5.6 months (range,3-13).Forty patients suffered bone nonunion or bone defect; after treated by fracture fixation,bone graft or bone transport,all of them got bone union.Conclusion The external fixation can shorten operation time as well as the time of limb ischemia,which is an effective option on repairing vascular injuries in knee and calf.

The individual intervention control of risk factors in high-risk population is one of key preventive measures of chronic disease.A total of 312 volunteers consulted physicians in one selected community.And 23 high-risk individuals of chronic disease were screened.The physicians customized the limit or requirement of diet,activity,tobacco and alcohol for each individual and made interventions of life behaviors according to the plans.The results showed that physical state of 20 (87％) of them converted from high-risk to health after interventions.Therefore customized control plan of individual risk factors is an effective control method of chronic disease.

To refine and analyze the characteristics and laws of acupoint selection in treatment of hyperlipidemia with acupuncture and moxibustion. By retrieving the main databases of Chinese and English version, the clinical research literature is included on the definite acupoints for hyperlipidemia treated with acupuncture and moxibustion, and the characteristics and laws are analyzed on the acupoint selection for hyperlipidemia treated with acupuncture and moxibustion. It is found out that the special points have been mainly used in treatment of hyperlipidemia. The first five top acupoints of high frequency use include Fenglong (ST 40), Zusanli (ST 36), Sanyinjiao (SP 6), Neiguan (PC 6) and Tianshu (ST 25). Totally 10 meridians are involved in acupoint prescriptions. The meridians of higher frequency use include the Stomach Meridian, the Spleen Meridian, the Conception Vessel, the Bladder Meridian and the Pericardium Meridian. The specific points are mainly from the Stomach Meridian, the Spleen Meridian, the Conception Vessel, the Bladder Meridian and the Pericardium Meridian in the treatment of hyperlipidemia. The acupoint prescription of acupuncture and moxibustion for hyperlipidemia is characterized as determining the treating principle based on the spleen theory, selecting the acupoints along the running courses of the spleen and stomach meridians, combining the nearby acupoints with the distal ones, selecting the acupoints for adjusting the deficiency and excess of zangfu and syndrome differentiation, collaborating the acupoints located in the front and on the back, as well as supplementing the acupoints based on symptoms.
