1.Problems and challenges confronting ideological and political work in hospitals
Chinese Journal of Hospital Administration 1996;0(10):-
At present ideological and political work in hospitals is characterized by limitedness, openness, autonomy and extensiveness. In doing ideological and political work in hospitals, it is therefore important to create for the staff diversified ideological platforms, extensive participation platforms, and swift and smooth information platforms. It is also essential to guide the ideological and political work in hospitals with a scientific view of development, adhere to people-oriented and scientific development, keep up with the times, constantly make innovations, and provide powerful intellectual impetus to hospital reform and development.

Objective To investigate the protective effect of rhein lysinate (RHL)on the liver of the models with diabetic rats,and to provide basis for research on treatment of fatty liver in the patients with diabetes mellitus. Methods The models of diabetic rats were established by intraperitoneally injecting streptozotocin(STZ).40 rats were divided into control,model,25 mg·kg-1 RHL,and 50 mg·kg-1 RHL groups(n=10).The levels of malonaldehyde (MDA)and the activities of superoxide dismutase (SOD)and glutathione peroxidase (GSH-Px) were detected by thiobarbituric acid method, pyrogallol autoxidation method, and NADPH coupling method, respectively.The pathological changes of liver tissue were observed by hematoxylin and eosin (HE)staining;the content of fat in liver tissue was observed by Nile red staining;the expression levels of fat synthesis-related proteins were detected by Western blotting method.Results Compared with control group,the body weight of the rats in model group was decreased and the levels of blood glucose,total cholesterol(TC)and triglyceride(TG)were increased (P<0.05);the activities of SOD and GSH-Px in liver tissue were decreased (P<0.05);there were a plenty of fat vacuoles and fat accumulation in liver tissue. The signal pathway of fat synthesis-related ERK1/2-SREBP-1c was activated in model group;compared with model group,it was inhibited in 25 and 50 mg· kg-1 RHL groups (P<0.05).Compared with model group,the blood glucose,TC and TG of the rats in 25 and 50 mg ·kg-1 RHL groups were decreased (P<0.05);the activities of SOD and GSH-Px were increased (P<0.05);however the body weight had no change. Compared with model group, the fatty vacuoles and the fatty accumulation of liver tissue in 25 and 50 mg·kg-1 RHL groups were decreased. Conclusion The hepatic protection of RHL is correlated with the inhibition of oxidative stress, fat degeneration and fatty accumulation of liver tissues.

Objective:To explore the relationship between the lipid accumulation product index (LAP) and the risk of carotid atherosclerosis in different gender groups.Methods:The data of 2 740 employees of Dalian municipal government and institutions, including 1 583 males and 1 157 females, who had underwent physical examination in Dalian Municipal Central Hospital Affiliated of Dalian Medical University from January to June 2018 were analyzed retrospectively. The general data, laboratory indexes and carotid ultrasound data of the population were collected, and the body mass index (BMI) and LAP value were calculated. According to carotid intima-media thickness (IMT), the subjects were divided into carotid atherosclerosis group (IMT ≥ 1.0 mm) and carotid normal group (IMT<1.0 mm). The clinical indicators between the two groups were compared. Independent risk factors for carotid atherosclerosis were analyzed by binary Logistic regression, and the cutoff point for predicting carotid atherosclerosis by LAP was calculated by receiver operating characteristic (ROC) curve.Results:The age, waist circumference (WC), hip circumference (HC), LAP, BMI, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), fasting plasma glucose (FPG), systemic blood pressure (SBP), diastolic blood pressure (DBP) and the prevalence of hypertension and diabetes in the male and female population carotid atherosclerosis groups were significantly higher than those in the normal group ( P<0.05). The results of binary Logistic regression analysis showed that after adjusting age, BMI, HC, WC, smoking, drinking, hypertension, diabetes, TC and LDL-C, the risk of carotid arteriosclerosis still increased 1.316 times with each quartile interval of LAP in women ( OR= 1.316, 95% CI 1.063 to 1.629, P = 0.012). In men, after adjusting for these factors, the independent effect of LAP on the risk of carotid atherosclerosis disappeared. In women, the area under curve (AUC) of LAP in predicting carotid atherosclerosis was 0.713, significantly higher than that of BMI (AUC 0.614) and WC (AUC 0.654), and the differences were statistically significant ( P<0.05). But there was no significant difference among the three indexes in the male population in predicting carotid atherosclerosis. According to ROC curve, the best cut-off value of LAP for predicting carotid atherosclerosis was 32.13 cm·mmol/L in men and 33.70 cm·mmol/L in women. Conclusions:LAP is an independent risk factor for carotid atherosclerosis in female population, and its predictive ability for carotid atherosclerosis is higher than that of body mass index and waist circumference. LAP ≥ 33.70 cm·mmol/L can be used as the best cut-off value for screening carotid atherosclerosis in female population.

A 19-year-old man was admitted to the hospital for erythema and nodules on the face and postauricular region for 6 years. Microscopic examination of lesion scrapings revealed brown septate hyphae. A restricted, velvety and black colony grew on Sabouraud's dextrose agar. Slide culture on potato dextrose agar plate showed flask-shaped phialides at the apex of or around the hyphae with clear collarettes and flaring apex,mucilage-encapsuled, round to oval, semi-endogenous phialosporae accumulating at the apex of the phialides,giving a flower-like appearance. Anti-fungal susceptibility test showed that the fungus was sensitive to itraconazole, terbinafine and amphotericin B, but resistant to fluconazole. Sequence analysis of the ITS1-ITS4 region revealed a 98% consistency with the reference sequence of ITS1-ITS4 of Phialophora verrucosa. On the basis of above findings, the patient was diagnosed with cutaneous phaeohyphomycosis. Clinical improvement was seen after treatment with oral itraconazole (400 mg/d).

Objective To investigate nerve growth factor (β-NGF) and its receptors expression in human pancreatic ductal adenocarcinoma. Methods Expression and distribution of β-NGF, tyrosine kinase A (TrKA) and P75NGFR were detected in operation tissue specimens of pancreatic ductal adenocarcinoma with immunohistochemistry and real-time PCR. Relations of β-NGF and its receptors with clinicalpathological characters, especially nerve invasion were analyzed. Results β-NGF and TrKA expression are higher in pancreatic adenocarcinoma than normal pancreas, and the differences are significant (P < 0. 01). Β-NGF and TrKA expression are associated with the differentiation grades(DG), lymphatic node metastasis, nerve invasion and surgical pathological stages. Poorer of DG and later stages, more expression of β-NGF and TrKA. Β-NGF and TrKA expression have positive correlations. Β-NGF, TrKA and P75NGFR mRNA expression have significantly increased 3.84,4. 23 and 2. 41 times than normal tissues by real-time PCR, respectively. Conclusions β-NGF and TrKA might play potential rules in carcinogenesis for pancreatic cancer,have affinity with clinicopathological characters of pancreatic cancer. Β-NGF and TrKA may have mutual effect in signal transduction leading to perineural invasion of pancreatic carcinoma.

Objective To investigate the role of and relationship between reactivity to autologous serum and dermatophagoides farinae (Df) in the pathogenesis of chronic urticaria (CU). Methods Autologous serum skin test (ASST) and skin prick test (SPT) to Df were carried out in 831 patients with CU. The correlation between reactivity to autologous serum and Df was statistically analyzed. Results The positivity rate of ASST and SPT to Df was 51.74% and 64.62%, respectively in the 831 patients. SPT was positive in 56.52% of patients with positive ASST and in 73.86% of those with negative ASST (P < 0.05). In patients with positive ASST, the degree of autologous serum reactivity was negatively correlated with that of reactivity to Df (P < 0.05). Conclusions The skin reactivity to Df and autologous serum plays an important role in the pathogenesis of CU, and the degree of the reactivity to Df and autologous serum is negatively correlated. To conduct ASST and SPT simultaneously in patients with CU may favor the clinical classification and therapy of CU.

Objective To detect the expression levels of the miR-205 in lung cancer tissue and A549 cells and its targeted gene YES1 using qRT-PCR and dual fluorescence protein repoter assay system,and to explore the possible mechanism of miR-205 to inhibit the proliferation of lung cancer A549 cells.Methods The expression levels of miR-205 in 10 cases of lung cancer tissue and adjacent normal lung tissue were detected with qRT-PCR.The cell growth curve and colony formation assay were used to determine the proliferation rate of A549 cells after transfected by miR-205 mimics and control mimics.The sequences of YES1 3′UTR (untranslated region)and mutation target sites of YES1 3′UTR were inserted into the plasmid which expressed green fluorescence protein (pcDNA3/EGFP) respectively to construct the green fluorescence protein plasmids of YES1-3′UTR and mut-YES1-3′UTR. There were six groups in the study:YES1-3′UTR, YES1-3′UTR and miR-205 mimics, YES1-3′UTR and control mimics,mut-YES1-3′UTR, mut-YES1-3′UTR and miR-205 mimics, mut-YES1-3′UTR and control mimics;after the plasmids expressed red fluorescent protein (pDsRed2-N1 )were cotransfected into A549 cells,the extracted protein was detected with fluorescence spectrophotometer.Results Compared with adjacent normal lung tissue,the expression levels of miR-205 in lung cancer tissue and A549 cells were decreased (P<0.05 );the proliferation rate of A549 cells in miR-205 mimics group was lower than that in control mimics group (P<0.05). The fluorescence protein expression level in YES1-3′UTR and miR-205 mimics co-transfected group was lower than that in YES1-3′UTR and control mimics co-transfected group, the difference was statistically significant (P<0.01).The number of cell colony formation of A549 cells in highly expressed YES1 group was higher than that in cell control group (P<0.05).Conclusion MiR-205 may inhibit the proliferation of A549 cells through regulating of the expression of YES1 directly.miR-205 and YES1 are potential therapeutic targets for the biological treatment of tumor.
