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 study the methods of graduation of benign prostatic hyperplasia.Methods Transrectal digital palpation,transabdominal and transrectal ultrasonography,uroflowmetry and measuring residual urine volume were carried out for 320 cases of benign prostatic hyperplasia.Results①The measuring prostatic volume by means of transrectal digital palpation and ultrasound was similar.There was no significant difference between the groups(P=0.991).②The obstructive degree of the urethra was not consistent with the prostatic volume(P<0.01),it was closely related to the degree and site of hypertrophy node.③Measurement of size of prostatic internal gland,proportion between internal and external gland,site of internal ostium of urethra and sonography during urination were carried out by transrectal ultrasonography.The results were similar with obstruction pressure of the urethra and clinical manifestation(P=0.848, 0.966,0.592).Conclusions The transrectal ultrasonography graduation is not only a reliable method for diagnosis of benign prostatic hyperplasia,but also can guide the treatment of benign prostatic hyperplasia.

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.

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.

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 evaluate the structure and stiffness of the common carotid artery (CCA) in patients with obstructive sleep apnea syndrome (OSAS) by RFQIMT and RFQAS technology and analyze the relationships between the parameters of CCA and cardiovascular risk factors.Methods 113 participants with habitual snoring suspected OSAS were divided into control group,mild,moderate and severe OSAS groups according to apnea hypopnea index(AHI)＜5,5-20,20-40,＞40 event/hour respectively.Carotid parameters included intima-media thickness (IMT),diameter (D),distension (Dis),distensibility coefficient (DC),compliance coefficient (CC),pulse wave velocity (PWV),stiffness index α and β were collected by RFQIMT and RFQAS.Multivariate linear regression analysis was applied to analyze the relationships between CCA parameters and cardiovascular risk factors.Results ①The clinical characteristics:blood pressure had significant difference among the four groups (P ＜0.05).SO2,SO2 min decreased and T90,ODI increased significantly in mild,moderate and severe group (P ＜0.05).②The structure parameters of CCA:IMT,D and plaques had no significant difference among the four groups (P ＞0.05).③The elasticity parameters of CCA:Compared with control group,Dis increased significantly in mild group (P ＜0.05).PWV,α,β increased significantly in moderate group (P ＜ 0.05).Compared with mild group,PWV,α,β increased significantly in moderate group (P ＜0.05).Compared with moderate group,α,β increased significantly in severe group (P ＜0.05).④By multivariate linear regression analysis,age was an independent predictor of IMT,Dis,D,CC,PWV,α,β(P ＜0.05).A blunted nocturnal fall was an independent predictor of D,DC,CC,PWV (P ＜0.05),SBP,DBP and PP of daytime had an important effect on D (P ＜0.05).SO2 was independently correlated with PWV (P ＜0.05).PP was an independent predictor of PWV,α,β (P ＜0.05).Smoking was an independent predictor of plaque (P ＜0.05).Conclusions ①Stiffness is damaged earlier than morphology of CCA in patient with OSAS.②PP,a blunted nocturnal fall and SO2 are correlated with stiffness of CCA significantly.It indicates that abnormal circadian blood pressure rhythm and hypoxia are associated significantly with stiffness of CCA in patient with OSAS.

pancreatic carcinoma by some signal transduction.

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 explore therapeutic effect of recombinant human brain natriuretic peptide (rhBNP) in aged patients with acute decompensated heart failure (ADHF).Methods: A total of 98 aged ADHF patients treated in our hospital were selected and randomly divided into routine treatment group (n=50) and rhBNP group (n=48, received intravenous injection of rhBNP based on routine treatment group).After 72h treatment, cardiac function indexes, total effective rate and incidence of adverse drug reactions (ADR) were measured and compared between two groups.Results: Compared with before treatment, after 72h treatment, there were significant rise in left ventricular ejection fraction (LVEF) and 24h urine volume in both groups(P=0.001 all);compared with routine treatment group after treatment, there were significant rise in LVEF [(45.9±7.8)% vs.(57.4±7.9)%] and 24h urine volume [(1637.5±103.2)ml vs.(1836.4±118.4)ml], P=0.001 all.On 7d after treatment, total effective rate of rhBNP group was significantly higher than that of routine treatment group (93.75% vs.82.00%, P=0.033).There was no significant difference in incidence rate of ADR between two groups, P=0.898.Conclusion: Recombinant human brain natriuretic peptide can significantly improve heart function, and the therapeutic effect is significant in aged patients with acute decompensated heart failure.
