With the developmetn of the medical humanistic education,more and more problems appear.The casualness of the medical humanistic curriculum,the monotony of the method of the evaluation,the insufficiency of the content,the inadequacy of the quality of the teachers,and the poor effect of the education are the factors affecting the development of our medical humanistic education.Through comparison of the humanistic education home and abroad,we find the key to these problems are the innovation of the curriculum and evaluation.

Objective To investigate the expression of pSTAT5 in 7 pancreatic carcinoma cell lines,and the change of expression of pSTAT5 in pancreatic carcinoma cells SW1990 after growth hormone (GH) treatment, and explore its molecular mechanism. Methods Human pancreatic carcinoma cell lines (SW1990, Cap-1, Colo, Mia, AsPc, P3, PANC1) were cultured in vitro, and Western blotting was used to detect the expression of pSTAT5 in these cell lines. SW1990 in exponential growth phase was collected and nude Balb/c mice were inoculated with SW1990 cells. When tumors became palpable after inoculation, mice (normal saline group). 1 h, 2 h and 24 h after the last dose of GH treatment, the mice were sacrificed.Western blotting was used to detect the expression of pSTAT5 in SW1990 and inoculation tumor cells after GH injection. Results Positive expression of pSTAT5 was observed in all human pancreatic carcinoma cell lines (SW1990, Cap-1, Colo, Mia, Aspc, P3, PANC1). 5 minutes after GH (50 ng/ml) stimulation, the expression of pSTAT5 in SW1990 was 0.57 ±0.05, which was significantly increased; and it reached 0.64 ±0.04 at 10 minutes, then decreased to 0.39 ±0.03 at 15 minutes, however, it remained higher than that in the control group at 1 h (0.33 ± 0.02 vs 0.25 ± 0.06), and its expression at 2 h was 0.26 ± 0.03 and returned to the normal level. The expression of pSTAT5 in xenograft was not significantly changed. Conclusions GH could rapidly up-regulate the expression of pSTAT5 in SW1990 but the effect lasted for a relatively short period. GH had no significant effect on the expression of pSTAT5 in xenograft.

OBJECTIVETo get the message about the developing feature of pneumoconiosis by analyzing the data from 353 cases of pneumoconiosis diagnosed in our hospital recent 6 years.

METHODSTo analyze the onset age, onset service years and incubation period of 353 cases of pneumoconiosis, especially in silicosis, coal worker's pneumoconiosis and potter's pneumoconiosis.

RESULTS353 patients referred to 10 species of pneumoconiosis, the silicosis, coal worker's pneumoconiosis and potter's pneumoconiosis were accounted for 28.90%, 43.34% and 15.01% of total pneumoconiosis respectively. Diagnosed patients who began to exposed to dust during 1950's to 1980's accounted for 84.99% of all the diagnosed patients. The onset age, onset service years and incubation period of silicosis, coal worker's pneumoconiosis and potters pneumoconiosis all showed a shorten trend compared each other every decade, especially after 1980's, but excluded potter's pneumoconiosis because of that the ceramics industry switched to other products in Beijing. There was a positive correlation relationship between average onset age and incubation period in three main species of pneumoconiosis mentioned above, but no significant difference could be seen in average promotion years. Additionally, comparing with other type of work, jade machining workers showed such a characteristic as younger onset and short incubation period.

CONCLUSIONThe development situation of silicosis, coal worker's pneumoconiosis is still no so optimistic, and the strict surveillance and administration especially to the township enterprises with poor production conditions should get further strengthen.

BACKGROUNDMiR-34a dysregulation has been implicated in tumorigenesis and progression of gastric cancer, but its role in prognosis of patients with gastric cancer remains unknown. The aim of this study was to investigate the expression and prognostic significance of miR-34a in gastric cancer patients after radical gastrectomy.

METHODSQuantitative real-time polymerase chain reaction was performed to detect the expression of miR-34a in human gastric cancer cell lines and tissues in 76 patients with gastric adenocarcinoma from China. Results are assessed for association with clinical features and overall survival (OS) using Kaplan-Meier analysis. Prognostic values of miR-34a expression and clinical outcomes were evaluated by Cox regression analysis. A molecular prognostic stratification scheme incorporating miR-34a expression was determined using receiver operating characteristic analysis.

RESULTSThe results show that the expression level of miR-34a was decreased in human gastric cancer cell lines and tissues, and down-regulated expression of miR-34a was associated with Lauren classification (P = 0.034). Decreased miR-34a expression in gastric cancer tissues was positively correlated with poor OS of gastric cancer patients (P = 0.013). Further multivariate Cox regression analysis suggested that miR-34a expression was an independent prognostic indicator for gastric cancer (P = 0.027). Applying the prognostic value of miR-34a expression to tumor node metastasis (TNM) stage system showed a better prognostic value in patients with gastric cancer than miR-34a expression (P = 0.0435) or TNM stage (P = 0.0249) alone.

CONCLUSIONThe results reinforce the critical role for the down-regulated miR-34a expression in gastric cancer and suggest that miR-34a could be a prognostic indicator for this disease.

Objective To investigate the changes in CD8+T lymphocyte count and effect on immune function in patients with sepsis after continuous renal replacement therapy (CRRT).Methods General data of septic patients who admitted to the emergency department of a hospital between October 2015 and August 2016 were collected,pe-ripheral blood was taken from patients before and after single CRRT,the total CD8+T cell count,interferon-γ(IFN-γ)-secreting CD8+T cell count,the levels of inhibitory molecules and costimulatory molecules as well as IFN-γand tumor necrosis factor-α(TNF-α)produced by CD8+T cells were detected.Results A total of 37 hospitalized septic patients were infected with gram-negative bacteria, pathogens causing infection were Klebsiella pneumoniae (22 strains),Acinetobacter baumannii (1 1 strains),and Enterobacter cloacae (3 strains).After CRRT,the body temperature,heart rate,white blood cell count,urea nitrogen,and serum creatinine levels in septic patients were all lower than those before CRRT (all P＜0.05).After CRRT,the total CD8+T cell count in septic patients didn’t change significantly (P＞0.05),but IFN-γ-secreting CD8+T cell count increased (P＜0.05).Levels of cytotoxic T lymphocyte-associated antigen 4(CTLA-4),programmed death-1 (PD-1),T-cell immunoglobulin and mucin-do-main-containing molecule 3 (TIM-3)after CRRT were all lower than those before CRRT (all P＜0.05 ),while levels of costimulatory molecules CD28 and secreting IFN-γ elevated after CRRT(all P＜0.05).Conclusion CRRT can not only improve the vital signs and renal function of patients with sepsis,but also enhance the immune function of CD8+T cells.

OBJECTIVETo investigate UbcH10 expression in hepatocellular carcinoma and explore its clinicopathological implications.

METHODSWe detected UbcH10 mRNA expression using RT-PCR in normal liver cell line, cancer cell lines, surgically removed hepatocellular carcinoma tissue and corresponding adjacent non-tumor tissue and evaluated the clinicopathological significance of UbcH10. Immunohistochemistry was performed to investigate UbcH10 protein expression in hepatocellular carcinoma tissue, the adjacent tissue, and normal liver tissue specimens.

RESULTSNormal liver cell line L02 showed significantly lower UbcH10 mRNA expression levels than the cancer cell lines BEL-7402, Hep3B, HepG2 and SMMC-7721 (P<0.05). UbcH10 mRNA expression was also was significantly higher in hepatocellular carcinoma tissues than in the corresponding non-tumor tissues (P<0.05). Clinicopathological evaluation suggested that UbcH10 expression was associated with tumor invasion of the portal vein, tumor size, TNM staging, and tumor differentiation (P<0.05). Immunohistochemistry identified stronger UbcH10 expression in hepatocellular carcinoma tissues than in the adjacent tissues and normal liver tissues (68.6%, 28.6%, and 26.7%, respectively).

CONCLUSIONUbcH10 is over-expressed in hepatocellular carcinoma and may serve as a novel biomarker as well as a therapeutic target of hepatocellular carcinoma.
