The long-acting cabotegravir and rilpivirine injection regimen（CAB+RPV regimen）is the first approved long-acting antiretroviral therapy（ART）for HIV in China，administered once every two months. This regimen provides an innovative alternative to daily oral ART，benefiting virologically suppressed patients. Several large clinical-studies have shown that the CAB+RPV regimen achieves comparable virologic suppression and safety to daily oral regimens，while significantly enhancing patient satisfaction. Based on international and domestic HIV/AIDs guidelines and clinical evidence，this consensus offers expert recommendations on patient selection，clinical management，and key communication strategies for healthcare providers to support the effective use of this regimen，aiming to improve quality of life for people living with HIV and accumulate domestic clinical experience with this advanced treatment approach.

Objective To analyze and summarize the risk factors of failed internal fixation for intertrochanteric fracture.Methods From April 2008 to April 2011,267 patients with intertrochanteric fractures in 4 hospitals were treated with internal fixation.The relationship between the failure of internal failure and possible factors as age,gender,hypertension,diabetes,the abuse of alcohol and tobacco,use of glucocorticoid,the degree of osteoporosis and fractures type were studied.According to the surgical risk assessment table,the patients were divided into low-risk,mid-risk,and high-risk group.The rate of internal fixation failure was compared in the 3 groups.Results We found 42 cases which showed radiographic failures.The internal fixation failure directly related with advanced age,diabetes,severe osteoporosis,unstable type fracture,but not gender,hypertension,the abuse of alcohol and tobacco,use of glucocorticoid.Risk factors of internal fixation failure included diabetes,osteoporosis degree,and fracture stability.Failed intertrochanteric fracture fixation mainly occurred in the mid-risk and high-risk groups.Conclusion Severe osteoporosis,unstable fracture,diabetes are risk factors of failure of intertrochanteric fracture fixation.These factors will affect the quality of surgery.For the patient with intertrochanteric fractures in the low-risk groups,internal fixation should be the first choice for treatment.For the patients in the mid-risk and high-risk group,internal fixation should be applied cautiously.For the aged patients in high-risk groups,hip arthroplasty is a wise option.

Objective Analysis of the expression of CD38,CD133 antigen and their clinical significance in myelodysplastic syndrome (MDS).Methods CD38 and CD133 antigen were analyzed by flow cytometry in 31 cases of MDS patients.Results CD38 was expressed in 18 cases (58.1% ),among them,12 cases were found to be myelodysplastic syndrome refractoryanermia ( MDS-RA ),accounting for 57.1%,6 cases were found to be MDS-RAEB,accounting for 66.7%.CD133 was expressed in 20 cases(64.5% ) ,among them,11 cases were found to be MDS-RA ( 52.4% ),1 case MDS-RAS,and 8 cases of MDS-RAEB,accounting for 88.9% .CD38 expressed significantly higher in MDS than anemia and relatively normal group ( P ＜ 0.05 ).CD133 expression in anemia groups was different from MDS-RA without statistical significance ( P ＞ 0.05 ),but was significantly different from relatively normal group (P ＜0.05).CD133 expression was significantly higher in these with MDS-RAEB than those in anemia and normal group ( P ＜ 0.05 ).Conclusions Combining with conventional antibodies,flow cytometry used in detection of CD38 ,CD133 ,could improve the diagnostic rate of MDS.

The resident infection rate of schistosomiasis in Xinnong Village,Chuanxin Town,a national surveillance site of schistosomiasis.decreased to 0.14% in 2008.which suggested that the surveillance site reached the criteria for trammission control.
