RESUMO
Objective@#To evaluate the effects on reduction of peripherally inserted central catheter-related venous thrombosis by hand grip exercise.@*Methods@#A detailed search was performed to identify literature about the impact of handgrip exercise on peripherally inserted central catheter-related venous thrombosis, using the Cochrane Library and the databases of PubMed, CINAHL, Embase, CNKI, WanFang and CBM. The meta-analysis or descriptive review were performed after two authors in-dependently searching databases,extracting data and assessing quality of included studies.@*Results@#Seven RCTs were included in a total of 789 patients. Meta-analysis showed the effectiveness of handgrip exercise on reduction of peripherally inserted central catheter-related venous thrombosis (RR=0.27, 95% CI 0.17-0.42, P<0.01); and improving vein maximum velocity (WMD=6.53, 95%CI 3.34-9.73, P<0.01) and time-mean flow velocity (WMD=6.05, 95%CI 3.24-8.87, P<0.01).@*Conclusions@#Handgrip exercise can improve axillary vein blood flow parameters and reduce peripherally inserted central catheter-related venous thrombosis. Due to a small number of included studies and heterogeneity of indicators, multi-centered, high-quality RCTs with large sample size are needed in the future to assess the effect of handgrip exercise in PICC patients.

RESUMO
Objective To discuss the pathological and clinical characteristics,treatments and prognosis of schwannoma of the kidney.Methods Two cases of schwannoma of the kidney in our hospital were reviewed with clinicopathological data and their follow-up.The related literatures were reviewed.The first case was a male patient,28 years old,complained about paroxysmal abdominal pain with nausea over 2 weeks.The physical exam found a 10 cm,qualitative hard,poor activity,tenderness mass in kidney region.MRI preoperative diagnosis was right renal cell carcinoma with renal vein and inferior vena cava tumor thrombus formation.The second patient,female,53 years old,the mass on upper right kidney was found occasionally.It was diagnosed as adrenal pheochromocytoma before operation,laparoscopic resection of right renal hilum mass and right partial adrenectomy plus right nephrectomy were performed.There was no tumor recurrence in the follow-up.Results The abdominal aortography and double renal arteriography were done and right renal artery embolization and inferior vena cava filter were allocated.Then right radical nephrectomy and inferior vena cava tumor thrombus removal were carried out on the first patient.The first malignant and the second benign renal schwannoma patient showed significant difference in pathological presentations.Their immunohistochemistry also showed great diversity.Malignant renal schwannoma was significantly stained by Ki-67 ＞ 40％,S-100 was negative.Ki-67 in benign neurilemmomas was about 2％,and S-100 in benign renal schwannoma was positive.Conclusions Schwannoma of the kidney is rare with a favorable prognosis.The golden standard of diagnosis is pathology.Surgical resection has become the first choice for treatment.Recurrence and malignant transformation would happen after the surgery so that all the patients should be followed up.
