OBJECTIVE: To investigate the curative effect of electrocorticography (ECoG) monitoring in the microsurgical treatment of cavernous angiomas. METHODS: Clinical data of 71 patients with epileptogenic cavernous angiomas,who had been performed ECoG monitoring during the operation,were analyzed retrospectively. RESULTS: The foci of cavernous angiomas and epilepsy of the 71 patients were resected during the operation. In the 58 patients who were followed up,42 had not epileptic seizure,and 16 still had epileptic seizure,while the frequencies of 13 patients reduced to below 10%,and 3 patients over 10%. CONCLUSION The drug treatment of epileptogenic cavernous angiomas can not control epileptic seizure,and the patients should receive the microsurgical treatment early. Electrocorticography monitoring can direct the surgical procedure,and control the postoperative epileptic seizure.

Objective To observe the effects of aerobic training and aerobic combined with resistance training on motor function, like muscle strength,cardiopulmonary endurance and so on,in patients with chronic kidney disease(CKD). Methods From July,2015 to August,2016,60 patients with CKD were randomly divided into control group(A,n=20), aerobic training group(B,n=20)and aerobic combined with resistance training group(C,n=20).Group B per-formed cycle ergometer at 50% peak oxygen uptake(VO2peak)for 30 minutes a time,and group C performed one section of Thera-Band resistance training based on group B, three times a week for twelve weeks.All patients were evaluated with one repetition maximum-upper limb (1 RM-U), one repetition maximum-lower limb (1 RM-L),Cardiopulmonary Exercise Test(CPET),Arm Curl Test(ACT),30-second Chair Stand(CS-30),Six-Min-ute Walk Test(6MWT),and estimated gomerular filtration rate(eGFR)and serum creatinine(sCr)were calculat-ed and recorded before and after training. Results There was no significant difference in all indexes among three groups before training(F<1.841,P>0.05).After training,all indexes improved in groups B and C(t>2.162,P<0.05),and were better in groups B and C than in group A(t>2.132, P<0.05).After training, 1 RM-U, 1 RM-L, VO2peak,ACT, CS-30 and 6MWT were better in group C than in group B(t>2.081,P<0.05). Conclusion Aerobic training could improve the motor function of patients with CKD,and it is more effective combined with resistance training.

Objective To study the relationship between the expression of apoptosis inducing factor (AIF) and neuronal apoptosis in rats with focal ischemia reperfusion.Methods Wistar rats were divided into sham-operated (n=6) and model (n=30) groups.Middle cerebral artery occlusion (MCAO)models were established by thread ligation.The expression of AIF in the ischemic penumbra was observed in the sham-operated and model groups 6 h and 1,2,3 and 7 d after the reperfusion; the changes of neuronal apoptosis in corresponding region were observed by TUNEL staining at the same time.Results AIF-positive cells in the ischemic penumbra were significantly increased in the model group 6 h after the ischemic reperfusion,reaching its peak level at 48 h of reperfusion (130.47±11.32 cells).Cell apoptosis occurred at each time point of ischemic reperfusion and the percentage of apoptosis cells at 48 h ofreperfusion (118.53±11.67 ceils) was the highest among all the time points.Significant differences between the 2 groups were found between each 2 time points (P<0.05).Conclusion Focal ischemia reperfusion can induce the increased expression of AIF positive cells and neuronal apoptosis.

BACKGROUNDSeveral isoforms of p53 have been reported, which may have varying functions and expressions. This study aimed to analyze the expression patterns of p53 isoforms in renal cell carcinoma (RCC) at the mRNA and protein levels and their associations with clinical and pathologic factors to explore the mechanism of p53 isoforms' activity in RCC.

METHODSThe specimens of tumours (T) and clinically normal tissues (N) adjacent to them were collected from 41 patients with RCC. mRNA expression levels of p53 isoforms were detected using RT-PCR followed by nested PCR. Protein expression levels were detected using immunohistochemisty and Western blotting with the anti-p53 antibodies DO-1 and DO-12. The data were analyzed with clinicopathological features by chi(2) test or Fisher's exact test.

RESULTSp53 mRNA was expressed in all tumours and matched clinically normal tissue adjacent to the tumour. All six isoforms could be detected in tumour and normal tissues, with the exception of the Delta133p53beta isoform, which was not detected in the normal tissue. Of the six isoforms, p53beta mRNA was significantly overexpressed in tumour samples (P < 0.001), and correlated with tumour stage. Nested PCR results consistently indicated the presence of p53gamma (19T/22N), Delta133p53 (33T/26N), Delta133p53beta (2T/0N), and Delta133p53gamma (13T/9N). Immunohistochemical analysis showed that p53 was expressed only in tumour tissues and correlated with tumour stage and grade. The results of Western blotting analysis were consistent with these findings.

CONCLUSIONSAlthough all six isoforms are present in RCC, their function in tumour development or progression might be different. Our findings suggest that p53beta might play an important role in the formation of RCC and it might be used as a new predictor and therapeutic target for RCC.

OBJECTIVEThe pathogenesis of minimal change nephrotic syndrome (MCNS) remains unclear. This study aimed to investigate the expression of interleukin-6 (IL-6) in rats with doxorubicin-induced nephropathy and its possible roles in the pathogenesis of MCNS.

METHODSEighty-three male Wistar rats were randomly assigned into a control group (n=32) and a nephropathy group (n=51). Nephropathy was induced by a single tail vein injection of doxorubicin (5 mg/kg). The control group was injected with normal saline. Twenty-four-hour urinary protein excretion was measured 7, 14, 28 and 42 days after doxorubicin injection. IL-6 expression in urine and renal tissues was determined using ELISA 7, 14, 28 and 42 days after doxorubicin injection.

RESULTSThe urinary protein excretion increased significantly in the nephropathy group 7, 14, 28 and 42 days after doxorubicin injection compared with that in the control group (P<0.01). IL-6 expression in urine and renal tissues increased significantly 7, 14, 28 and 42 days after doxorubicin injection compared with that in the control group (P<0.01). IL-6 expression in urine and renal tissues was positively correlated with 24-hour urinary protein excretion in the nephropathy group (r=0.794, P<0.01; r= 0.870, P<0.01). IL-6 expression in urine was positively correlated with that in renal tissues (r=0.739, P<0.01).

CONCLUSIONSIL-6 expression in the urine and renal tissues is increased in MCNS rats. IL-6 might play an important role in the pathogenesis of MCNS.

Background & Objective: Radiotherapy and temozolomide are the standard therapy for newly diagnosed glioblastoma multiforme (GBM). However, it is unclear whether adding another agent to the commonly used radiotherapy-temozolomide (RT + TMZ) benefits newly diagnosed GBM patients. The present network meta-analysis aimed to assess the efficacy of combining other agents with RT + TMZ for GBM treatment. Methods: A comprehensive literature search was conducted on PubMed, EMBASE.com, Web of Science, and the Cochrane Central Register of Controlled Trials from inception to September 23, 2014, to include all randomized controlled trials of RT + TMZ-based therapy in GBM patients. Pairwise and network meta-analyses were performed to compare the therapeutic regimens. Results: Seventeen studies involving 4,148 patients were identified. The results of pairwise meta-analysis indicated no significant differences among most comparison groups, except for bevacizumab + RT + TMZ versus RT + TMZ for progression-free survival (hazard ratio [HR] = 0.71, 95% confidence interval [CI]: 0.59–0.86; P = 0.000) and RT + TMZ versus RT alone for overall survival (HR = 0.71, 95% CI: 0.58–0.88; P = 0.001). The results of network meta-analysis also showed no significant differences in most comparisons; however, adverse events were more common among patients receiving additional therapeutic agents other than RT + TMZ. The ranking probability analysis indicated that bevacizumab + RT + TMZ and nimustine + cisplatin + RT + TMZ were associated with the best progression-free and overall survival, but they also caused the most adverse events in GBM patients. RT + bevacizumab + irinotecan had the highest probability of being the best regimen for minimizing adverse events. Conclusions: The addition of other targeted agents, particularly bevacizumab and nimustine, to RT + TMZ could be slightly effective for the treatment of newly diagnosed GBM patients; however, adverse events remained common.

Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.
