Objective:To analyze the effects of the clinical applications of vaccine for esophageal cancer to provide treatment ba-sis. Methods:Tumor-soluble antigen was extracted from clinical samples of esophageal cancer tissue. Vaccine for esophageal cancer was prepared using antigen and superantigen staphylococcal enterotoxin C (SEC). One group of patients with esophageal cancer was treated with vaccine after surgery (treatment group). Another group of patients with esophageal cancer was treated using routine meth-ods (control group). After five years, the patients were followed up to analyze survival. Results:After five years of follow up, the sur-vival rates of treatment and control groups were 173/328 (49.71%) and 67/326 (20.55%), respectively. Survival rates significantly dif-fered between the two groups (P<0.05). Furthermore, the survival rates of the female patients were higher than those of the male pa-tients (P<0.05). In the treatment group, the survival rates of patients with low-differentiation cancer were higher than those of patients with high-differentiation cancer (P<0.05). In the control group, the survival rates of patients with low-differentiation cancer were lower than those of patients with high-differentiation cancer (P<0.05). Conclusion:Tumor vaccine prepared with esophageal cancer antigen and superantigen SEC could increase the survival rate of patients with esophageal cancer, particularly female patients and those with low-differentiation cancer.

Objective To explore the anticancer mechanism of esophageal cancer vaccines and clinical effect.Methods Esophagus cancer cells (Eca109) were cultured and the soluble antigen were extracted from the cells.Esophagus cancer vaccine was constructed with the antigen and superantigen SEC.Lymphocytes were isolated from peripheral blood and then stimulated with the vaccine in vitro.Phenotypes of the cells were checked by FCM and killing activity was tested with cytotoxic assays.One hundred and six early esophageal cancer patients were selected after surgery,who were divided into the observation group of 53 cases with esophageal cancer vaccine therapy and 53 cases in the control group with conventional treatment.Then clinical effect was observated and 3 year follow-up survival rate was observed of the of two groups of patients.Results Proliferation of vaccine stimulated lymphocyte group was the strongest,and high peaked at 72 h (A =0.22),and raise CD8+ T cell populations of CTLs.The killing activity of lymphocyte group stimulated by the vaccine against target cells was significantly higher than that of lymphocyte group ((97.36±2.11) ％) vs.(79.27±5.57) ％,F =38.62,P＜0.01).Three years follow up shows that the survival rates of experiment group were 48.27％ (male) and 45.83％ (female) respectively,and control group were 21.43％ (male) and 24.00％ (female),and the difference was significant (x2 =5.06,6.28,P ＜ 0.05).Conclusion The tumor vaccine constructed with esophagus cancer antigen and superantigen SEC can induce PBMC to activate and proliferate into CD8+ CTL with specific cytotoxicity against the cells which the antigen comes from.The vaccine may raise the survival rate of the patients with Esophagus cancer.

ApoE ε4 was more frequent in VD than in MCI （P=0.044）. ConclusionApoE ε4 allele is a risk factor in AD, and may be associated with VD and MCI.

We detected Zika virus (ZIKV) in a febrile case returning from Suriname and entry China from Guangzhou Baiyun International Airport Port.Serum and saliva samples were collected from a suspected case returning from Suriname.We detected ZIKV RNA using real-time fluorescence RT-PCR methods by both in-house reagent and commercial detection kits.RT-PCR detection was carried out with saliva sample and sequence analysis was performed.Phylogenetic tree was constructed to analyze the source of imported cases.Real-time fluorescent RT-PCR result showed that saliva was detected ZIKV RNA positive while for serum was weakly positive.A specific 1 500 bp fragment in size was amplified with saliva sample by RT-PCR.Sequence analysis showed 99％ homologous to the corresponding sequence of Brazil ZIKV (GenBank No.KX197250).Phylogenetic tree indicated it was located on African lineage.According to the epidemiological investigation results,clinical manifestations and nucleic acid detection of case,the suspected case was confirmed to infect Zika virus,being the first case from Suriname into Guangdong Province.

Our primary health care institution began to implement national essential medicine system in 2009. In past fi ve years, the goal of national essential medicine system has been initially achieved. For examples, medicine price is steadily reducing, the quality of medical services is improving and residents' satisfaction is substantial increasing every year. However, at the same time, we also found some urgent problems needed to be solved. For examples, the range of national essential medicine is limited, which is difficult to guarantee the quality of essential medication. In addition, how to compensate the primary health care institution is still a question.

Objective:To investigate the effect of triptolide on the apoptosis of human melanoma A375 cells through the inositol-requiring enzyme 1 (IRE1) /c-Jun N-terminal kinase (JNK) signaling pathway, and to explore its possible mechanisms.Methods:Cultured A375 cells were treated with triptolide at different concentrations of 0, 50, 100, 200 nmol/L (experimental control group, 50, 100, 200 nmol/L triptolide groups, respectively), and a blank control group (DMEM high-glucose medium without cells) was set up. Methyl thiazol tetrazolium (MTT) assay was performed to evaluate the cell viability at 24, 48, and 72 hours after the start of treatment, flow cytometry to detect cell apoptosis at 24 hours after the start of treatment, and real-time fluorescence-based quantitative PCR (RT-qPCR) and Western blot analysis were conducted to determine mRNA and protein expression of IRE1, JNK, and c-Jun, respectively. After pretreatment with the JNK inhibitor SP600125 for 72 hours, some A375 cells were then treated with 100 nmol/L triptolide for 24 hours (SP600125 + 100 nmol/L triptolide group), and the A375 cells only treated with 100 nmol/L triptolide served as control group (100 nmol/L triptolide group). Effects of triptolide on the mRNA expression of IRE1, JNK, and c-Jun in A375 cells, as well as on cell apoptosis, were investigated. Statistical analysis was performed using two-way analysis of variance, one-way analysis of variance, and Dunnett′s test.Results:After the treatment with different concentrations of triptolide for different durations, the cell viability was significantly lower in all triptolide groups than in the experimental control group ( Ftriptolide concentration = 18.36, P = 0.002), and gradually decreased over time ( F time = 8.54, P = 0.018). After 24-hour treatment, the apoptosis rate of A375 cells significantly differed among the 4 groups treated with different concentrations of triptolide ( F = 5 234.97, P < 0.001) ; additionally, the apoptosis rate was significantly higher in the 50, 100, and 200 nmol/L triptolide groups (16.99% ± 0.33%, 30.78% ± 0.40%, 38.91% ± 0.51%, respectively) than in the experimental control group (4.33% ± 0.02%, all P < 0.05), and gradually increased with the rising concentrations of triptolide. The mRNA expression levels of IRE1, JNK, and c-Jun were all significantly higher in the 50, 100, and 200 nmol/L triptolide groups than in the experimental control group (all P < 0.05), and gradually increased with the increase of triptolide concentration. Moreover, the protein expression levels of IRE1, JNK, c-Jun, p-JNK, and p-c-Jun in A375 cells in the triptolide groups also showed the same trend. After pretreatment with the JNK inhibitor SP600125 for 72 hours, the apoptosis rate was significantly lower in the SP600125 + 100 nmol/L triptolide group (21.88% ± 0.55%) than in the 100 nmol/L triptolide group without SP600125 pretreatment (30.78% ± 0.40%, t = -22.51, P < 0.001), and the mRNA expression levels of IRE1, JNK, and c-Jun were also significantly decreased in the SP600125 + 100 nmol/L triptolide group compared with the 100 nmol/L triptolide group (all P < 0.05) . Conclusion:Triptolide may induce apoptosis of human melanoma A375 cells by activating the IRE1/JNK signaling pathway.

Objective: Cognition impairments are considered as a fundamental characteristic of severe mental disorders (SMD). Recent studies suggest that hyperprolactinemia may exert a detrimental influence on cognitive performance in patients with SMD. The objective of this study was to investigate the correlation between serum prolactin levels and cognitive function in female individuals diagnosed with SMD. Methods: We conducted a study on 294 patients with SMD and 195 healthy controls, aged between 14 to 55 years old. Cognitive function was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), while prolactin levels were measured in serum. Descriptive analysis and comparative analysis were performed to compare cognitive function and prolactin levels between groups, and linear regression models were used to explore the relationship between prolactin and cognitive function. Results: Compared to the healthy control, individuals with SMD exhibited significantly higher levels of prolactin, while scoring lower on RBANS total and every index scores. Furthermore, a negative association between prolactin levels and cognitive function (RBANS total index score, attention, and delayed memory) was observed in SMD patients. Importantly, this inverse correlation between prolactin and cognition function (RBANS total index score, total scale score, and attention) persisted in patients who were not taking medications that could potentially influence serum prolactin levels. Conclusion Our study reveals a significant correlation between elevated prolactin levels and cognitive impairment in female patients with SMD, underscoring the importance of monitoring prolactin levels in order to prevent cognitive deterioration among female SMD patients.
