Hepatocellular carcinoma(HCC) is the fifth most common cancer and the third cause of cancer-related death worldwide;meanwhile,it is also one of the fastest growing malignancies.The causes of HCC are multiple;HBV is the most important cause in China,with about 25%-30% of HBV infection patients finally develop hepatic cirrhosis and liver cancer.At present,large scale epidemiological studies revealed that the metabolic syndrome(MS) was closely related to liver cancer,and it even served as an independent risk factor for the occurrence and progression of liver cancer.Non-alcoholic fatty liver disease is a metabolic syndrome clinically manifested in the liver;recently it has been indicated to be closely related with HCC development and progression.This paper reviews the recent researches on metabolic syndrome and liver cancer,so as to provide literature for preventive and therapeutic studies on non-virus-related liver cancer.

Objective To investigate the clinical manifestations,pathological features,treatment and prognosis of nongesta-tional choriocarcinomas.Methods The clinicopathological data in 4 cases of nongestational choriocarcinoma were retrospectively analyzed and the relevant literatures were reviewed.Results All 4 patients had no confirmed diagnosis at first visit to hospital.All patients received the operative therapy and postoperative bleomycin,etoposide and cis-platinum (BEP)regimen chemotherapy.The followed up lasted for 3-32 months.One case died at postoperative 26 months due to pulmonary metastasis;one case was loss of follow up;two cases had relatively favorable condition.Conclusion Nongestational choriocarcinoma is a rare and highly invasive trophoblastic neoplasm,and is prone for early distant metastasis.The treatment is recommended to adopt operation combined with postoperative combined chemotherapy of multiple drugs.

Objective To approach the feasibility of identifying the specific biomarker of ovarian cancer by SELDI TOF mass spectrometry. Methods The relative contents of serum protein of both 24 the patients with ovarian cancer and 56 cases of healthy people were tested by IMAC3 chip and proteinchip reader (CipherGen Inc., VS). Results On the M/Z values ranged from 4000Da to 10000Da, there were six kinds of protein contents in the serum of the were obviously different between the two groups. Among them the serum protein of M/Z value 4472Da may be regarded as a specific biomarker of ovarian cancer. In the learning mode, all the 24 patients and 56 control people were diagnosed and distinguished out correctly, while in the test mode, 23 patients were correctly diagnosed and 56 control people were distinguished out, the total accuracy was 98 75%(79/80), and the sensitivity and specificity were 95 8%(23/24) and 100%(56/56), respectively. Conclusion Ovarian cancer can be quickly and correctly diagnosed by this method with high sensitivity and specificity. That will be widely used in clinical application

Objective To establish a serum protein fingerprinting technique with a pattern matching algorithm to distinguish Dukes A stage from colorectal cancer of Dukes B,C,D stage. Methods Serum samples were collected from both reserved group and test group, each of the groups comprised 10 patients of colorectal cancer in Dukes A stage and 68 patients in Dukes B,C,D stage. The sera of the reserved group was combined with the surface of the IMAC3 proteinchip. Then the data of SELDI TOF MS was read and analyzed by BioMarker Wizard software and BioMarker Pattern software to get a classificatory pedigree tree, which is a standard configuration that can distinguish the sera of colorectal cancer patients of Dukes A from colorectal cancer patients of Dukes B,C,D, and the standard was confirmed by double blind test in the test group. Results At the M/Z values of 8 320 Da, 8 604Da, 8 867Da and 15 872Da, the protein contents in reserved group are obviously different between the two classes of patients. The accuracy of classification was 97 4%(76/78), corresponding sensitivity was 100%(10/10) and corresponding specificity was 97 1%(66/68). By double blind examination in test group, the corresponding accuracy was 100%(10/10), the corresponding sensitivity was 94 1%(64/68) and the corresponding specificity was 94 1%(64/68). Conclusion Colorectal cancer of Dukes A can be quickly and exactly diagnosed by this method with high sensitivity and specificity. That will be widely used in clinical application

Objective To investigate the effect of oral exercise method combined with shaker exercise on dysphagia in patients with cerebral hemorrhage.Methods 112 patients with dysphagia caused by cerebral hemor-rhage were randomly divided into control group (28 cases,conventional treatment),oral exercise method group (28 cases,conventional treatment combined with oral exercise method),shaker exercise group (28 cases,conventional treatment combined with shaker exercise)and combination group (28 cases,conventional treatment combined with oral exercise method and shaker exercise).Four groups were assessed with video fluoroscopic swallowing study (VF-SS)before treatment and after treatment.Results (1)There were no differences on VFSS among four groups before treatment (P >0.05).After treatment,there were significant differences on VFSS among four groups(F =9.40,P <0.05).Combination group[(8.68 ±4.74)points]with the highest score,followed by shaker exercise group[(6.52 ± 3.12)points]and oral exercise method group[(6.43 ±2.84)points],control group[(3.96 ±2.02)points]with the lowest score.There were no differences on VFSS between before treatment and after treatment in control groups (F =0.945,P >0.05).In the remaining groups,the scores of VFSS after treatment were significant higher than that of before treatment (P <0.05).(2)The total effective rate in combination group was higher than that of the remaining groups(χ2 =37.76,P <0.01).Combination group (96.43%)combined with the highest total effective rate,followed by shaker exercise group (75.00%)and oral exercise method group (71.43%),control group (21.42%)combined with the lowest total effective rate.Conclusion The application of oral exercise method combined with shaker exercise on patients with dysphagia caused by cerebral hemorrhage could improve the swallowing function.

BACKGROUND: Carbamylated erythropoietin (CEPO) cannot only remarkably promote the prognosis of cerebral infraction, but also improve the microcirculation. OBJECTIVE: To explore the underlying mechanism of CEPO promoting the microcirculation following cerebral infraction. METHODS: 150 Wistar rats were selected, and 120 rats were used for establishing the models of cerebral infarction, followed by allotted into four groups. The model rats were treated with 500, 1000 and 2000 u/kg CEPO as experimental groups, and those received no treatment as model group. The other 30 rats were as controls. Vascular endothelial cells were isolated and cultured in vitro, and the cell proliferation was detected by cell counting kit-8 assay. The expression levels of proliferation-related genes (Ki67 and p16) and vascular endothelial growth factor (VEGF) were detected using western blot assay. After selective silencing of VEGF through RNA interference, all above indicators were detected again. RESULTS AND CONCLUSION: Cell counting kit-8 assay results showed that the proliferation ability of vascular endothelial cells was increased with CEPO concentration increasing. Western blot assay results showed a significant upregulation of Ki67, p16 and VEGF. After shRNA-VEFG interference, these indicators had no positive correlation with the increased concentration of CEPO. Our findings indicate that CEPO can improve the proliferation of vascular endothelial cells in an animal model of cerebral infarction via upregulating the VEGF expression.

Objective To evaluate the method and outcome of surgical treatment for refractory slow-transit constipation (STC). Methods Clinicopathologic data of 24 patients with severe STC which underwent (colectomy) in recent years were retrospectively analyzed. Results 18 of the patients underwent pancolectomy,and 6 underwent subtotal colectomy. All of the 14 STC patients complicated with outlet obstructive (constipation)(OOC) were corrected preoperatively by related surgery. The curative rate of surgical (treatment) was 95.8%,with an average of(3?1.9) times of bowel motion per day. The incidence of (abdominal) distention decreased from 75% to 12.5%. One patient who underwent ileorectal anastomosis (developed) recurrent constipation. Conclusions Colectomy produces satisfactory results in the majority of (patients) with refractory slow-transit constipation.Patients complicated with OOC should undergo energetic (preoperative) correction therapy,in order to ensure a satisfactory surgical outcome.
