Objective To summarize the safety and efficacy of Sunitinib in the treatment of metastatic renal clear cell carcinoma. Methods Fifteen patients with clear cell metastatic RCC were treated with Sunitinib,with 11 males and 4 females,aged from 26 to 74 years with median age of 55 years.Thirteen cases of 15 were T3 to T4 stage,and 8 cases underwent radical nephrectomy,while 5 other cases underwent renal biopsy with the pathological diagnosis of renal cancer.The other two cases (one man and one woman)with the solitary kidney renal cell carcinoma ( stage T1a) and renal insufficiency,were diagnosed as metastatic renal cell carcinoma by biopsy.Sunitinib monotherapy was administered by the regimen of 6 weeks per cycle with daily oral Sunitinib 4 weeks,followed by 2 weeks off ( from 1 - 10 cycles).Response was evaluated by RECIST.Renal tumor was 9.52 ± 3.3 cm in diameter at baseline,and the assessment of metastases included retroperitoneal lymph nodes (6 cases),mediastinal lymph nodes (3 cases),brain (2 cases),lung (6 cases),bone (2 cases) and liver (2 cases).Karnofsky score,tumor changes,adverse events and the survival of each patient was assessed and recorded. Results The follow-up duration was from 1.5 - 15months,with median follow-up of 6 months,and tumor response was evaluated by RECIST.Seven of 15 patients (46.7%) treated with Sunitinib achieved partial responses (PR),7 patients (46.7%) demonstrated stable disease (SD),and 1 patient (6.7%) developed progressive disease (PD) during the follow-up.Objective Response Rate (ORR) was 46.7%,PR + SD was 93.3%,6 months PFS was 93.3%,and median PFS was 12 months,respectively.Renal tumor was 8.7 ± 4.0 cm in diameter after therapy.Two PR patients with the obvious effectiveness had experienced progressed hypertension,and one cases with hypertension that could be controlled below 140/90 mm Hg ( 1 mm Hg =0.133 kPa) by a single drug before treatment,showed increased blood pressure ( > 160/105 mm Hg) following the second cycles treatment,who were administered increased dosage and combination therapy.The other case without history of hypertension,showed high blood pressure ( > 150/100 mm Hg) in the third cycle,and could be controlled well by antihypertensive drugs.Fortunately,the tumor of these two cases reduced obviously by more than 50%. 1/2 adverse reactions of 12 cases:yellowing of the skin and yellow sweat ( 12 cases,80% ),fatigue ( 12 cases,80% ),4 cases of hypothyroidism (26.7%),bilirubin and triglyceride levels elevated in 7case (46.7%); Four cases showed 3/4 degree adverse events with the emergence of gastrointestinal bleeding in one case secondary to platelets reduction (6.7%).Three cases (20%) showed serious fatigue,nausea,vomiting and severe hand-foot skin reaction. Conclusions Sunitinib is recommended for the treatment of metastatic renal clear cell carcinoma with good efficacy and safety.

OBJECTIVETo measure hip bone mineral density (BMD) on different femoral rotations and to identify the influence of femoral rotation during hip densitometry.
METHODSForty women were recruited at the out-department of orthopedic, with the average age of 60.7 years (45-85 years), the average height of 161.8 cm (150-175 cm), and the average weight of 67.4 kg (48-80 kg). BMD measurement of hip was done in neutral position (0 degrees), 15 degrees and 30 degrees of internal rotation under quality control of DXA machine. All the subjects were asked to get down scan table and reposition after each measuring in different rotation.
RESULTSHip BMD of proximal femur (femoral neck, Ward's area and trochanter region) have significant variations in measurement (P < 0.01) among neutral position, 15 degrees and 30 degrees of internal rotation. There were more BMD change at the cancellous region (Ward's triangle and trochanter region) than at cortical bone area (femoral neck region). Statistical analysis showed a significant positive correlation for hip BMD change between neutral degrees to 15 degrees of internal rotation and 15 degrees to 30 degrees of internal rotation. But no correlation between neutral degrees to 30 degrees of internal rotation for hip BMD change.
CONCLUSIONSFemoral rotation was shown to have a significant effect on hip BMD measurements. Cortical bone region of hip have a less BMD change than cancellous bone region. Proper positioning of the femur during scan can improve precision significantly.

In order to explore the genotype distribution and molecular evolution of non-polio enterovirus (NPEVs)in Yunnan Province,the People's Republic of China, we sequenced and analyzed the partial VP1 coding region of 105 NPEVs isolated from acute flaccid paralysis (AFP) surveillance in Yunnan province during a 5- year study period from 2006 to 2010. The viral genomes of 105 NPEVs were translated to corresponding amino acid sequences and compared with those of the prototype strains, and the phylogenetic tree was constructed among these VP1 nucleotide sequences and other prototype strains from GenBank. Analysis showed that 18 isolates were classified into 7 serotypes of human enterovirus A species, while 77 isolates into 22 serotypes of B and 10 isolates into 4 serotypes of C species. However, we did not isolate any viruses which belonged to human enterovirus D species. Thus, under AFP surveillance, human enterovirus B species accounted for 73. 3% of the 105 isolates and was considered as the predominant one,followed by human enterovirus A(17. 1%) and human enterovirus C(9. 5%). Phylogenetic analysis showed that various serotypes of the virus and the corresponding prototype strains or other representative strains clustered into the same grooup, however, Yunnan strains and prototype strains were located in the different branches (except CA2,EV90 and EV76). The degree of variation was different even among the same genotype strains. This report showed that different genotype strains spread widely in Yunnan Province.

Deep vein thrombosis(DVT)is a common complication after surgery for lower limb fracture.It has the features of high morbidity,high disability rate and high mortality.At present,the measures for clinical prevention and treatment of post-operative DVT in lower limb fracture mainly include perioperative nursing,intervention with medical auxiliary instruments,western medicine prevention and treatment,traditional Chinese medicine(TCM)intervention,and patients'self-cooperation.The patients'self-cooperation is the basis for the smooth implementation of other measures for prevention and treatment,and the patients'active cooperation is the premise of achieving the efficacy of prevention and treatment.Perioperative nursing is helpful for the patients to understand the risk factors of postoperative DVT and the possible risks after the occurrence of DVT,guides the patients to choose the food,assists the patients to do postoperative exercises,improves the level of patients'hemorheological indexes,and reduce the incidence of postoperative DVT.Medical devices are helpful for assisting patients to do postoperative rehabilitation exercises,improving the levels of hemodynamic indicators,promoting patients'rehabilitation and reducing the incidence of postoperative DVT.Western medicines such as low molecular weight heparin,Rivaroxaban,Enoxaparin and other anticoagulant drugs can reduce the aggregation of coagulation factors and blood viscosity,and reduce the incidence of postoperative DVT.TCM interventions mainly include oral administration of Chinese medicine and external treatment such as acupuncture,moxibustion and massage.Oral administration of Chinese medicine is helpful for improving blood flow status.Acupuncture,moxibustion and massage are beneficial to the activation of the function of zang-fu organs,and can stimulate the healthy qi to improve the qi-blood state of the whole body.Each method of prevention and treatment has its advantages and disadvantages.In clinical application,reasonable prevention and treatment methods should be selected according to the specific conditions and individual conditions of the patients.TCM intervention of DVT can be performed in patients with lower limb fracture before and after surgery,and has the advantages of low cost and definite efficacy,which is worthy of continuous research and inheritance and innovation.

OBJECTIVETo compare the safety, feasibility and efficacy of transperitoneal and retroperitoneal laparoscopic partial nephrectomy (LPN) in the treatment of renal tumors with R. E. N. A. L score more than 7.
METHODSThe clinical data were collected from 62 patients undergoing transperitoneal LPN (32 cases) and retroperitoneal LPN (30 cases) for a complex renal mass (R.E.N.A.L. score≥7) between January 2012 and March 2014. The surgical and early postoperative outcomes and complications were analyzed to evaluate the efficacy of the treatments. The mean operative time, estimated blood loss, warm ischemia time, surgical complications, blood transfusion rate, tolerating regular diet time, postoperative hospital stay and surgical margin were compared between the two groups.
RESULTSThe operations were completed successfully in all cases except for 1 case in transperitoneal group and 3 in retroperitoneal group that required conversion to open surgery. No significant differences were found in age, body mass index, ASA score, Charlson comorbidity index, tumor size or R.E.N.A.L. nephrometry score (P>0.05), nor in estimated blood loss, warm ischemia time, intraoperative complication, blood transfusion rate or surgical margin between the two groups (P>0.05, respectively). The transperitoneal LPN group had a shorter mean operative time than retroperitoneal LPN group (210.4∓59.2 vs 252∓58.3 min, P<0.05) but showed longer tolerating regular diet time (47∓10 h vs 23∓6 h, P<0.05) and postoperative hospital stay time (8.4∓1.9 days vs 6.5∓1.6 days, P<0.05).
CONCLUSIONBoth transperitoneal LPN and retroperitoneal LPN are safe, feasible and effective for surgical management of complex localized tumors, but the transperitoneal procedure offers larger operative space with better exposure; the retroperitoneal procedure better promotes postoperative recovery of the patients.
