Objective To explore the possibility of immune therapy for hepatocellular carcinoma (HCC) with MAGE-3 antigen peptide (FLWGPRALV). Methods The expression of HLA-A2 in HCC patients were examined with microcytotoxicity assay .The mRNA of MAGE-3 genes in the tumor tissues were detected by RT-PCR, the CD8 positive T lympocytes were separated as effector cells with immunobeads from peripheral blood mononuclear cells (PBMCs) of those patients. The irradiated autologous CD8 negative PBMC were pulsed with MAGE-3 peptide as APC. Some effector cells were co-cultured with APC, and some not as the control. After 14 days′ culture with IL-2, the frequency of effector cells secreting IFN-? in response to MAGE-3 peptide were monitored by IFN-? secretion assay. The hepatocellular carcinoma cell line HLE was used as the target cells.ResultsNine HCC patients were HLA-A2 positive in 25 HCC patients, and 3 of them were MAGE-3 mRNA positive. After two weeks′ culture, the effector cells increased by 4-6 folds. The frequency of CD8 positive cells secreting IFN-? in response to MAGE-3 peptide was 22.0% in 3 MAGE-3 mRNA positive patients(n=3),and 0.5% in 6 negative patients( n=6) (?

The contents of the total ash, acid- insoluble ash and water were similar in the different specifications and the total ash content was lower than 7 % which was in accordance with that recorded in China Pharmacopoeia.Conclusion Volatile oil, acid- insoluble ash, water and synephrine with a definite content limit can be chosen as the parameters for the research of quality standard of Frutus Aurantii Immaturus, which will supply evidence for the medicinal trade and research of Frutus Aurantii Immaturus.

Gender differences in fatigue, manifesting as female more prone to feel exhausted with lower muscle endurance, still remains unclear mechanism. Here, we investigated whether orosomucoid, an endogenous anti-fatigue protein which can enhance muscle endurance, is involved in this regulation. Female rats showed lower muscle endurance, and this gender difference was disappeared in orosomucoid 1-deficient mice. Female rats also displayed weaker orosomucoid induction in serum, liver and muscle in response to fatigue when compared to male ones. Ovariectomy in female rats results in elevated orosomucoid level and increased swimming time which was reversed by estrogen replenishment, while exogenous estrogen treatment both in male or female mice produced opposite effects. In vitro C2C12 muscle and Chang liver cells, estrogen decreased orosomucoid expression and its promoter activity, and this effect was abolished when estrogen receptor or MAPK was blocked. Thus, estrogen negatively regulates orosomucoid expression, which is responsible for the weaker muscle endurance in females.

This study was aimed to analyze the clinical features of paroxysmal kinesigenic dyskinesia (PKD) and extend the understanding of this disease. From August, 2008 to October, 2010, 9 patients were diagnosed with PKD in the Department of Neurology of the First Affiliated Hospital of Zhejiang University, China. The data involving clinical demographic characteristics, somatosensory evoked potentials, results of electromyography, video electroencephalography (EEG), brain magnetic resonance imaging (MRI) and computerized tomography (CT) were collected. All PKD patients exhibited unilateral or bilateral recurrent episodic dyskinetic attacks triggered by sudden voluntary movements. The duration of the attacks ranged from several seconds to one minute. The attack frequency ranged from approximately once in several months to more than 10 times in a day. Patients suffered from no conscious disorders during the attack, and no neurological signs were found during the period between attacks. No abnormal somatosensory evoked potentials were found. Routine EEG, video EEG monitoring or brain imaging showed normal findings. Classical treatment for anti-epilepsy, including carbamazepine and topiramate, was administered to the patients and proved to be effective. It was concluded that PKD is characteristically triggered by sudden voluntary movement; no abnormal electroneurophysiological findings are observed in PKD, and antiepileptic drugs are effective in treating the disorder.

Objective To analyze clinicopathologic characteristics and prognostic factors of the patients with invasive lobular carcinoma of breast. Methods Clinical data of 125 patients with invasive lobular carcinoma of breast treated at Cancer Center of Sun Yat-sen University from Jan. 1990 to Dec. 2008, were analyzed. The clinical characteristics, recurrence and survival of the patients were summarized. Results Median age of 125 patients was 45 years old (range, 27 to 76 years old). The patients with large tumor mass (≥ 3cm), positive local lymph node, more than Ⅱ stage and positive hormone receptor at diagnosis were 77 cases(61.6 %), 64 cases(51.2 %), 101 cases(80.8 %) and 112 cases(89.6 %), respectively. The median time of follow-up was 58 months (range, 11-222 months). Of the 125 patients, 32 had local recurrence and metastasis, and 18 died. The 5-year disease-free and overall survival rates were 82.2 % and 87.3 %, respectively. Multivariate COX regression analysis showed that whether endocrine therapy or not was only a prognostic factor of patients with invasive lobular carcinoma of breast. Conclusion There is no difference in media age of patients with invasive lobular carcinoma of breast at diagnosis from other pathologic type of breast cancer. These patients are usually with larger tumor masses, more lymph node metastasis and a higher proportion of positive hormone receptor. The prognosis of patients is not affected by clinicopathologic parameters.

Objective:To evaluate the effects of different denture cleansers on the physical and mechanical properties of heat-cured denture base resin.Methods:Heat-curing denture base resin samples were prepared and respectively immersed in Polident,Stera-dent,0.5% sodium hypochlorite solution and distilled water for 60 h.The flexural strength and elastic modulus were measured(n =10)using 3-point bending test in a universal testing machine.A surface analyzer was used to measure the surface roughness of each specimen(n =10).Results:There were no significant differences of flexural strength and elastic modulus among Polident,Steradent and distilled water(P >0.05).The 0.5% sodium hypochlorite treatment produced lower flexural strength and elastic modulus than the other cleaners(P <0.05).No statistical significance of roughness was found among the solutions(P >0.05).Conclusion:Both Poli-dent and Steradent don't affect the physical and mechanical properties of the heat-cured acrylic resin.0.5% sodium hypochlorite solu-tion doesn't affect the surface roughness,but decreases the flexural strength and elastic modulus of the resin.

Objective To evaluate the impact of obesity and spleen length on laparoscopic splenectomy combined with pericardial devascularization.Methods We retrospectively analyzed 121 patients with portal hypertension who underwent laparoscopic splenectomy combined with pericardial devascularization in our hospital.Using BMI,these patients were classified as the obesity and the non-obesity groups.Using length of the spleen,the patients were divided into two subgroups:spleen AC diameter ＞ 20 cm and spleen AC diameter ≤20 cm.Results (1) For the Obesity group,the operation time,the rate of conversion to open operation and the complication rate after operation were higher than the non-obesity group [(184.0 ± 49.0) min vs (142.0 ±39.0) min,26.1％ vs 8.0％,26.1％ vs 6.7％,respectively,P＜0.05].However,the differences were not significant for mean blood loss,intraperitoneal drainage and complication rate after operation.For patients with massive splenomegaly,the obesity group had higher rates of conversion into open operation and complication (42.9％ vs 11.7％,33.3％ vs 8.8％,respectively,P ＜0.05).For patients with non-massive splenomegaly,the differences were not significant between the obesity and non-obesity groups (P ＞ 0.05).(2) For obesity patients,the spleen AC diameter ＞ 20 cm group had a longer operation time and a higher rate of conversion to open operation [(224.0 ± 42.0) min vs (152.0 ± 44.0) min,42.9％ vs 12.0％,respectively,P ＜ 0.05].The length of spleen had no effect on the operation and its complication (P ＞ 0.05).Conclusions Obesity extended the operation time and increased the rates of conversion to open operation and complication after operation.The spleen length had a major impact on the rates of conversion to open operation and complication after operation for the groups of obesity patients.
