Objective To discuss the effect of comprehensive mental intervention on mental health and sleep quality among the crew members during the Escort Mission in the Gulf of Aden.Methods The same batch of two escort ships was divided into study group and control group.The study group was intervened by comprehensive psychological intervention methods involving diversified forms of psychological training, counseling, behavioral intervention and cooperation between various departments.A psychological survey was conducted with Symptom Checklist 90( SCL-90) , Self-rating Anxiety Scale (SAS), Self-rating Depression Scale(SDS) and Pittsburgh Sleep Scale(PSQI) before and 3 months after intervention. Results There was no significant difference between the two groups before intervention (P>0.05).After intervention,the score of SCL-90 of study group was significantly better than that of the control group in somatization,obsessive compulsive disorder,interpersonal relationship,depression, anxiety,bigotry and hostility (P<0.05), while the score of SAS and SDS was lower(P <0.05).Sleep quality, the time taken to fall asleep, sleep time, dyssomnia,sleep efficiency,daytime dysfunction factor and the total score of PSQI were significantly more desirable than in control group (P<0.01).Conclu-sion Comprehensive intervention can effectively improve mental health and sleep quality of the crew members in the escort mission in the Gulf of Aden.It is worthy of popularization and application.

Objective To establish the nonalcoholic fatty liver disease(NAFLD) model in SD rats and to investigate if endoplasmic reticulum stress(ERS) plays a role in the pathogenesis of NAFLD. Methods A total of 36 male SD rats were randomly divided into 4 groups: normal control group 1(N1,n=8), normal control group 2 (N2,n=8), model group 1(M1,n=10) and model group 2(M2,n=10). The two control groups were fed with normal diets, whereas the two model groups were provided diets enriched in fat (10% lard oil and 2% cholesterol). The rats in N1 and M1 groups were sacrificed at the 12th week, and those in N2 and M2 groups were sacrificed at the 20th week. The serum alanine aminotransferase (ALT), aspartate aminotransferase(AST), alkaline phosphatase (ALP), total protein (TP), triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL) were measured. The steatosis, immflamation and fibrosis of the liver were observed with HE and Masson staining. The expressions of GRP78, CHOP and procaspase-12 mRNA were tested using real-time PCR and the activation of procaspase-12 protein was detected by Western blot. Results At the 12th week, the liver index and the serum levels of ALT, AST,ALP,TP,TC,LDL in M1 group were significantly higher than those in N1 group (P<0.01), but HDL level was significantly lower in M1 group than that in N1 group (P<0.01). At the 20th week, the concentrations of TC and LDL in M2 group were significantly increased in comparison with N2 group. The histochemical study revealed that the hepatic steatosis and inflammation in M1 and M2 groups were more serious than those in N1 and N2 goups(P<0.01). The slight fibrosis was seen in M2 group. At the 12th and 20th weeks, the expressions of GRP78,CHOP and procaspase-12 mRNA and protein in M1 and M2 groups did not differ in N1 and N2 groups. Conclusions The fat-rich diet might successfully induce NAFLD in rats and there is no ERS observed in the study, which suggests that ERS may not be involved in the pathogenesis of NAFLD.

Objective To ivevstigate the feasibility, the effects and the therapy of peritoneal dialysis(PD) on severe acute pancreatitis (SAP). Method From January,2001 to Jaly 2006,48 patients of SAP were divided randomly into PD group and non-PD group in Qingzhou hospital. Both groups were treated by the conventional mode of therapy. In PD group , using the concept of PD,24 patients of SAP were treated with PD and NPD group were treated only with common therapy. The release time of abdominal pain and distention, CT scores, APACHE II scores, the time of hospital stay, cost of treatment in hospital, operative rate and rate of complications and recovered rate of the two groups were compared. Simutaneously. the concentration of serum and fluid filtrated inflammatory cytokines TNFα,IL-6,IL-8,IL-10 and CRP were also determined pro and post the therapy. Results In the PD and NPD group, the duration for disappear-ance of abdominal pain and tenderness,and amelioration for abdominal distension was (19.70 ±7.32) hvs. (81.46±36.68) h and (23.16±6.95) h vs.(78.19± 29.26) h;So that the PD group was precede to that in NPD group ( P < 0.05). The concentration of serum and fluid filtrated pro-inflammatory cytokines TNFα, IL-6, IL-8 and CRP at each observation points after PD was decreased significantly (P <0.05) in the PD group. But the concentration of the serum and fluid filtrated anti-inflammatory cytokines IL-10 was increased significantly (P < 0.05) as compared with that of the NPD group. Conclusions Through PD, the imbalance of pro-inflammatory and anti-inflammatory cytokines has been corrected at early stage of SAP. But the PD is method that is easy, quick, small wou-ndell,few complicated and effective in patients with early-phase SAP, and will be of great value in wide application and further study.

Objective To investigate the significance of renal tubular dysfunction in patients with refractoriness nephrotic syndrome(RNS)and the effect of interference treatment of Valsartan (VAL).Methods 79 cases of RNS and 68 healthy controls were recruited into the study. The 79 patients of RNS were divided randomly into the VAL group and the dipyridam group. On the basis of routine therapy, the VAL group was given VAL(80mg/d),and the dipyridam group taken dipyridam (150mg/d)orally for 12 weeks The glomerular tubular function(u-RBP,α1-MG,β2-MG,mAlb,NAG)were detected and the pathologic changes of tubukinterstitium were observed by using the methods of ELISA, biochemistry and scoring of the pathologic damage of tubulointerstitium before and after 12 weeks of VAL treatment in all of the cases. Results Urinary RBP,α1-MG,β2-MG,mAlb and NAG in all patients with RNS was evidently higher than that in healthy controls(P＜0.01).Those had positive correlations with damages of tubulointerstitium(r=0.436,0.626,0.499,0.668,0.657,P＜0.01).The interference outcome displayed that the excretion rates of urinary series of protein after oral use VAL in treatment group were markedly lower, while the control group had no distinct change. Conclusion There were various injury of tubulointerstitium and the disfiguration of renal tubular function in all cases with RNS. Damages of renal tubular function had positive correlation with tubulointemtitium injury and renal globular injury. Interference treatment with ARB in patients with RNS could improve renal tubular function, which is of great significance in delaying the progress of RNS.

Objective:To explore the expression of caveolin-1 (Cav-1) and Chitinase-40 (YKL-40) in acute cerebral infarction and the value of combined detection in prognosis evaluation.Methods:118 patients with acute cerebral infarction admitted to the First Affiliated Hospital of Hebei Northern University from January 2016 to June 2019 were selected as the research objects. According to the cerebral infarction volume, the patients were divided into small infarction group (<5 cm 3), middle infarction group (5-10 cm 3) and large infarction group (>10 cm 3). 108 healthy people were selected as the healthy control group. The serum levels of Cav-1 and YKL-40 were compared in the 3 groups, and the correlation between the degree of cerebral infarction and serum levels of Cav-1 and YKL-40 was analyzed. Receiver operating characteristic curve (ROC) was used to analyze the diagnostic value of the expression levels of Cav-1 and YKL-40 in patients with acute cerebral infarction; the patients were followed up for one year and the prognosis was evaluated by modified Rankin Scale (mRS); the correlation between serum Cav-1 and YKL-40 and prognosis was analyzed. Results:The expression levels of serum Cav-1 and YKL-40 in patients with acute cerebral infarction were significantly higher than those in healthy group ( P<0.001). The serum levels of Cav-1 and YKL-40 were positively correlated with the infarct volume of acute cerebral infarction ( r=0.854, P=0.004; r=0.867, P=0.002). ROC curve analysis showed that the sensitivity, Youden index and area under ROC curve of Cav-1 (21.78 μg/L) combined with YKL-40 (158.69 ng/ml) in the diagnosis of acute cerebral infarction were 85.59%, 0.532 and 0.896 (95% CI: 0.741-0.932), respectively, which were significantly higher than those of single index ( P<0.05). At 8 and 12 months of follow-up, the proportion of death and mRS score in the positive group were significantly higher than those in the negative group ( P<0.05). Conclusions:The serum Cav-1 and YKL-40 levels are significantly higher in patients with acute cerebral infarction. The combined examination of Cav-1 and YKL-40 can improve the diagnostic efficiency and has potential application value for early diagnosis and prognosis prediction of patients.

Objective To investigate the expression of transforming growth factor β1,transforming growth factor beta receptor(TBR)Ⅰ,TβR Ⅱ,Smad4 and C-Jun in rats with nonalcoholic fatty liver disease(NAFLD)and to find out the mechanisms of liver fibrosis in patients with NAFLD.Methods A total of 18 male SD rats were randomly divided into normal control group(n=9)and model group(n=9).The rats in control group were fed with normal diet,and those in model group were fed with fat-rich diet(consisted of 10%lard oil+2%cholesterol).An rats were sacrificed at the 20th week.The levels of TGFβ1,TβR Ⅰ and TβR Ⅱ mRNA were examined by RT-PCR.The expressions of TGFβ1 and Smad4 in liver tissue were detected by immunohistochemistry.The expression of C-Jun protein was detected by Western blotting.Results The NAFLD model was successfully established.The immunohistochemistry examination revealed that TGFβ1 and Smad4 were expressed weekly in control group,but strongly expressed in model group.RT-PCR showed that A values of TGFβ1,TβR Ⅰ and TβR Ⅱ mRNA were 0.46±0.12,5.z4±2.70 and 3.35±1.95,respectively,in model group,which were higher than those in control group(0.21±0.09,1.36±0.77 and 0.52±0.19,all P values＜0.01).The Western blotting results demonstrated that the expression of C-Jun protein in model group(0.93±0.41)was higher than that in control group (0.32±0.25,P=0.001).Conclusion TGFβ1/Smad4 signal pathway might be involved in the development of hepatic fibrosis in NAFLD.Blocking TGFβ1/Smad4 signal pathway will be helpful in treatment of NAFLD.
