Objective To investigate the causes and prevention on complications of percutaneous vertebroplasty(PVP). Methods Forty three cases with 64 vertebrae were performed PVP from May 2001 to October 2003. The incidence of complication was 13 cases (30.2%). Leakage of polymethylmethacry (PMMA) without symptoms occurred in 4 cases. Leakage with pain occurred in 3 cases. No leakage but with pain occurred in 4 cases after the procedure. Fracture of adjacent vertebrae occurred in 2 cases. All cases were followed up from 3 to 29 months (in average of 13.2 months). Results There wasn′t severe complications in 7 leakage cases. The pain in 7 cases was relieved and disappeared at 2-7 days after the procedure. The symptoms of pain in 2 cases of adjacent vertebrae fracture were relieved. Conclusion If sufficient preventive measures are applied before or during the procedure of PVP,the complications may be reduced effectively.

Primary liver cancer is one of the most common malignant tumors in the world, and hepatocellular carcinoma accounts for the majority of liver cancer. Hepatectomy is one of the most important treatment methods, but the high postoperative recurrence rate is the leading cause of treatment failure, which seriously reduces the long-term survival rate and reduces quality of life. Therefore, preventing the recurrence of liver cancer is an important part of treatment. At present, there is no standard program for the treatment of hepatocellular carcinoma to prevent recurrence after surgery, most of the treatment programs include transarterial chemoembolization, antiviral therapy, traditional Chinese medicine treatment, targeted therapy, immunity therapy, etc., which has certain clinical significance in preventing recurrence. This paper reviewed the research progress on preventing recurrence of hepatocellular carcinoma after surgery, which may provide guidance for the clinical study.

Branch atheromatous disease(BAD) refers to cerebral infarction that occurs at the opening or bifurcation of the perforating artery and is caused by the stenosis or occlusion of the lumen of the perforating artery due to atherosclerosis. Since BAD was proposed,it has attracted wide attention due to its characteristic imaging manifestations and clinical features of early neurological deterioration. However,since it is unable to visualize the perforating artery on conventional imaging,it is difficult to clarify and unify the diagnostic criteria and therapeutic strategies for BAD. The application of high-resolution magnetic resonance and high-field magnetic resonance can help to display the hemodynamics and luminal plaques of the perforating artery,which will provide assistance for the development of more high-level BAD studies. This article reviews the epidemiology,clinical and imaging manifestations,diagnostic criteria,and treatment of BAD,so as to improve the early identification of this disease among clinicians and provide a reference for the diagnosis and treatment of this diseases.

Objective To identify potential serum biomarkers specific for hepatocellular carcinoma (HCC).Methods Eighty-one patients wilh hepatitis B-related HCC and 80 healthy controls were randomly divided into a training set (48 HCC,47 controls) and a testing set (33 HCC,33 controls).Serum proteomic profiles were measured using surface-enhanced laser desorption/ionization time-offlight mass spectroscopy (SELDI-TOF-MS).A classification tree was established by the Biomarker Pattern Software.Candidate biomarkcrs were separated by HPLC and identified by MA1DI-MS/MS and database searching.Forty-eight patients with HCC,54 cirrhotic patients and 42 healthy subjects were clinically validated using candidate biomarkers by SELDI-Immunoassay.Real-time reverse transcriptase-polymerase chain reaction was performed to observe GRO-1 and Thrombin in 55 HCC tissues and 13 normal hepatolage tissues.Results Two up-regulated protein peaks were automatically chosen as a classification tree in the training set.These biomarkers were identified as thrombin light chain and CXC chemokines ligand 1 (GRO-1).The sensitivity and specificity of this classification tree were 89.6％.The multivariate model using the two biomarkers and alpha-fetoprotein (AFP) resulted in a sensitivity of 91.7％ and specificity of 92.7％,which was significantly better than AFP alone.The mRNA expression of GRO-1 and Thrombin were found in all HCC tissues.There were significant associations between GRO-1 gene expression and some clinical and pathological findings such as metastasis and recurrence (P＜0.05).Significant differences of 5-year survival rates wee observed among subgroups according to the expression of GRO-1 (P＜0.05).There were significant associations between Thrombin gene expression and some clinical and pathological findings such as recurrence and AFP (P＜0.05).Significant differences of 5-year survival rates were observed among the subgroups according to the expression of THROMBIN (P＜0.05).A positive correlation was found between GRO-1 and Thrombin (r=0.73,P＜0.01).Conclusion Thrombin light chain and GRO-1 are potential biomarkers of HCC.The expression of GRO-1 in HCC tissues was a valuable indicator in estimating metastasis and recurrence in HCC patients.

Objective To retrospectively assess the prognostic impact of diabetes mellitus (DM) on patients with hepatocellular carcinoma (HCC) after curative resection.Methods A total of 417 HCC patients who had undergone curative hepatic resection were included into two groups.108 patients were classified into DM group and 309 patients into the non-DM group.Overall survival,disease-free survival,postoperative morbidity and mortality were compared between the two groups after reducing confounding bias by propensity score matching.Independent prognostic predictors were determined by Cox proportional hazards model.Results Propensity score matching resulted in 89 patients in each group,and variables were balanced between two groups.In the matched cohort,DM and non-DM groups showed similar morbidity and 30-and 90-day mortality after curative hepatectomy (respectively x2 =0.837,x2 =Fisher,x2 =Fisher,all P ＞ 0.05),the 1-,3-,and 5-year overall survival rates were 82.0％,59.9％,and 33.4％ in DM group and 90.7％,79.1％,and 69.3％ in non-DM group,respectively(P =0.001),however,there was no significant difference in disease-free survival between DM and non-DM groups.Cox multivariate analysis revealed that DM is an independent risk factor for overall survival in patients with HCC after curative resection,but not for disease-free survival.Conclusions DM does not increase the postoperative morbidity or mortality for patients with HCC after curative resection,however,DM may increase the risk of mortality of HCC patients in the long-term.

Objective To explore the effect of preoperative antiviral therapy on hepatitis B virus ( HBV ) reactivation and postoperative liver function in perioperative patients with HBV-DNA-negative hepatocellular carcinoma(HCC).Methods 74 patients with preoperative HBV-DNA-negative scheduled which were analyzed.Patients were divided into two groups according to antiviral therapy or not:20 cases in antiviral treatment group received antiviral therapy for three days, 54 cases in non-antiviral teatment group did not receive antiviral therapy, and both groups received antiviral therapy after post-operative resuming to diets.The indicators of liver function and HBV-DNA levels were detected on pre-operative, post-operative 3rd and 7th day in two groups, and HBV-DNA-positive ( HBV-DNA>500 IU/mL) was defined as reactivation, conversely as inactivation.The indicators of liver function on pre-operative, post-operative 3rd and 7th day were compared between reactivation group and inactivation group.Results The reactivative rate was 21.6%(16/74) in all patients;27.7%(15/54) in pre-operative non-antiviral teatment group, 5.0%(1/20) in antiviral teatment group, and there was significant differences in reactivative rate between two groups ( P=0.035 ).The results of Logistic regression showed that pre-operative nonantiviral therapy was an independent risk factor of post-operative HBV reactivation (OR=13.952,95% confidence interval[CI]:1.358-143.379,P=0.027).The recovery of albumin (ALB) on post-operative 3rd, 7th days in antiviral treatment group was faster than those in nonantiviral treatment group, respectively (P=0.035,0.043).The recovery of ALB and alanine aminotransferase (ALT) on post-operative 7th day in reactivation group were slower than those in inactivation group, respectively (P=0.016, 0.048).Conclusion The pre-operative nonantiviral therapy is an independent risk factor of post-operative HBV reactivation in patients with HBV-DNA-negative HCC.The pre-operative antiviral therapy could inhibit post-operative HBV reactivation effectively and accelerate the post-operative recovery of liver function.
