Objective To explore the characteristic clinical profiles and treatment modalities of Fetal rhabdomyomatous nephroblastoma(FRN).Methods A retrospective study was conducted for 14 FRN patients from Jan.2000 to Oct.2015.Their clinical data were collected including clinical presentations,pathology and treatment modalities.There were 8 males and 6 females with a mean age of 23 months.There were 3 cases at left side and right side 5 cases,bilateral 6 cases.2 patients were classified as stage Ⅰ,1 stage Ⅱ,5 stageⅢ and 6 stageⅤ.Abdominal mass was the main clinical presentation in 11 patients,and 1 case with hematuria,1 with abdominal pain,and 1 with vomit.Most tumors showed cysts or completely solid from the ultrasonography.Computed tomographic scan revealed a large inhomogeneous enhancement tumor from the kidney pole with necrotic,cystic,bleeding or calcification.Ultrasonography and Computed tomography (CT) had no different performance from Wilms' tumor.9 patients received preoperative chemotherapy,and the response was none in all of them.8 unilateral patients underwent tumor nephrectomy and another 4 had nephron-sparing surgery.Results Pathology showed that FRN contained more than 70％ of fetal rhabdomyomatous tissue.Immunohistochemistry had no specificity,most FRN shows Desmin (+) and Myogenin(+).Bilateral FRN tumors were seen in 2,one side with FRN and another side with nephroblastomatosis were seen in 3,one side with FRN and another side with Wilm's tumor was seen in 1 patient.Postoperative pathology confirmed FRN in all 14 cases.All patients received postoperative chemotheraphy:Act-D and VCR for 6 month(stage Ⅰ),Act-D and VCR for 15 month(stage Ⅱ),Act-D +VCR + ADR and radiotherapy for 15 month(stageⅢ).During follow-up of 6 months to 15 years,10 of them were alive without tumor and no evidence of recurrence.Conclusions FRN is a rare histologic variant of Wilm's tumor with less aggressive behavior.FRN usually has a huge volume and is bilateral with a poor responder to preoperative chemotherapy,but it is associated with a generally favorable outcome.Surgery and chemically treatment appears the effective measure.

At present,the combined interventional therapy that is based on transcatheter arterial chemoembolization (TACE) technique can control the progression of primary hepatocellular carcinoma (PHC)in different degrees,at the same time the clinical objectives,such as relieving portal hypertension,eliminating portal vein occlusion,controlling refractory ascites and lowering upper gastrointestinal bleeding probability,can be reliably achieved.Thus,the quality of life of the patients can be effectively improved and the survival time will be reliably prolonged.This paper aims to make a comprehensive review about the medical articles concerning TACE combined with other interventional therapies for PHC complicated by portal vein tumor thrombus,which have been published both at home and abroad in recent years,in order to provide practical help for clinical diagnosis and treatment of PHC.

Objective To assess the safety and feasibility of CT-guided percutaneous argon-helium cryoablation in the treatment of adrenal tumors.Methods 1 7 patients with adrenal tumors were treated with CT-guided percutaneous argon-helium cryoablation. Three of these patients were retreated second cryoablation three months later due to the lager tumor diameters.Percutaneous tran-scatheter arterial embolization was performed in four patients because of rich blood supply before cryoablation.Continuous arterial blood pressure monitoring was performed in eight pheochromocytoma patients.Results Technical success was achieved in all pa-tients.There were no serious complications.Eight pheochromocytoma patients experienced a significant increase in systolic blood pressure and diastolic pressure when compared with the basic values (P <0.05).There were no enhancement on enhanced CT and/or up-take on FDG PET-CT in the ablated zones during the follow-up period (3-24months).Conclusion It is safety and efficacy of CT-guided percutaneous argon-helium cryoablation for adrenal tumor.It might be initial treatment of choice for the patients who were not suitable for resection.

Objective: To investigate the efficacy and safety of scolosis-specific exercises (SSE) in reducing adolescent idiopathic scoliosis (AIS) progression, and to provide a reference for developing and promoting AIS non-surgical treatment methods and public health decisions. Methods: By using "scoliosis" "spine" "scoliosis-specific exercises" "spinal deformities" "idiopathic" "adolescent" "etiology" "treatment" "exercise" as Chinese and English search terms, literature search was conducted in PubMed, Embase, Sport, Discus, Central, Web of Science and CNKI databases from December, 2019. The RevMan 5.3 software was used for Meta-analysis. Results: Compared with the control group, SSE shows positive effects on improving scoliosis, including reduction of Cobb Angle in cervical vertebra (n=245, MD=-6.88, 95%CI=-7.70--6.05,P<0.01), reduction of Cobb Angle in lumbar vertebra (n=135, MD= -6.85, 95%CI=-10.06--3.63, P<0.01), improvement of physiological curve of spine (n=217, MD=-4.13, 95%CI=-7.92--0.35, P<0.01); In terms of improving quality of life, compared with the control group, patients in the SSE group were better able to improve the function of SRS-22 (n=276, SMD= 2.00, 95%CI=1.69-2.30, P<0.01) and self-image of SRS-22 (n=250, SMD=0.86, 95%CI=0.58-1.14, P<0.01) and reduce the pain value of SRS-22 (n=206, SMD=0.81, 95%CI=0.51-1.10, P<0.01). Conclusion SSE treatment can better improve the function of AIS patients and obtain better orthopedic effects than other types of sports or standard nursing methods. In the future, more high-quality researches are needed to further evaluate the efficacy and safety of SSE treatment and other types of sports or standard care methods for AIS.

ObjectiveTo explore the effect of swimming on motor behavior and expression of brain derived neurotrophic factor(BDNF) and trkB in adrenal body.MethodsSD adult rats were divided into normal cotrol group and swimming group ( n=10 in each group).All rats in swimming group were subjected 6 weeks swimming for 1h each day.Motor performances including swimming speed and distance were recorded and expression of BDNF and trkB in adrenal body was measured.ResultsThere was a significant increase in swimming speed ( ( 157 ± 60) m/min) and distance ( (283.36 ±49.50)m) in swimming group,compared with control group ( (283± 60) m/min,( 156.92 ± 29) m) (P ＜ 0.05 ).Simultaneously,expression of BDNF in adrenal body had been significantly unregulated (0.93 ± 0.09 vs 0.56 ± 0.19 ) (P ＜ 0.05 ),while expression of trkB kept to be not changed.ConclusionSwimming increases notor ability in rats,and the possible mechanism may be related the upregulation of BDNF in adrenal body.

Objective To investigate the efficacy of transcatheter selective cystic arterial infusion chemotherapy embolization in the treatment of invasive bladder cancer with hemorrhage.Methods 81 cases of with invasive bladder cancer and hemorrhage treated by superselective intervention in hospital were selected,as well as postoperative complications and tumor volume changes were recorded in followG up.Results The success rate of intubation and embolization was 100%,the immediate hemostasis rate was 97.53%,and the preoperative bladder tumor volume (4.08±1.66)cm was significantly larger than that of the six months after surgery (3.45±1.33)cm.Conclusion Superselective cystic arterial perfusion embolization is a safe and effective treatment for patients with invasive bladder cancer complicated with hemorrhage.

Objective To investigate the clinical curative effect and significance of partial splenic artery embolization (PSE) for the treatment of patients with hypersplenism at high altitude region. Methods The clinical data of 66 patients with cirrhosis complicated by portal hypertension and hypersplenism, who lived in Xining City of Qinghai Province, the high altitude region in China, and were admitted to authors' hospital during the period from March 2015 to December 2016 to receive PSE, were retrospectively analyzed. White blood cell (WBC) count, red blood cell (RBC) count and platelet (PLT) count were calculated at one day before operation as well as at one, 7, 30 and 90 days after operation. Results The technical success rate of PSE was 100％. The mean WBC count determined at one, 7, 30 and 90 days after PSE was obviously different from that determined at one day before PSE, the differences were statistically significant (P＜0. 05). Conclusion For the treatment of patients with cirrhosis complicated by portal hypertension and hypersplenism, who live at high altitude region, PSE has reliable curative effect, therefore, this therapy is worth promoting in clinical practice.
