ObjectiveTo study the effect of hyperbaric oxygen therapy on the cholinergic neurons of hippocampus and praxiology of vascular dementia rats.MethodsThe vascular dementia models were made and divided into control and therapy group. After 30 days of HBO therapy, abilities of learning and memory of rats were tested by using the Morris water maze. Immunochemistry staining was used to observe the number of cholinergic neurons of CA1 subfield of hippocampus. ResultsAbilities of learning and memory of rats and the number of the neurons positive to ChAT like immunoreaction in the CA1 subfield of the hippocampus significantly increased in therapy group.ConclusionHyperbaric oxygen therapy is effective on the vascular dementia model rats.

Objective To evaluate the clinical features,therapies and prognosis in patients with mucosa-assoeiated lymphoid tissue (MALT) lymphoma in ocular adnexal marginal zone (OAML).Methods A retrospective analysis was made upon clinical data from 21 patients with OAML admitted into Beijing Tongren Hospital from June,2008 to December,2011.Results There were 12 (57.1 ％) men and 9(42.9％) women,with a median age of 57 (23-79) years old.Majority of patients had localized pathological changes.Among them,16 patients (76.2％) were in stage Ⅰ E,and 5 (23.8％) in stage Ⅳ E.Surgical resection as the sole treatment was performed in 13 patients (61.9％),and positron emission tomography CT(PET-CT) imaging demonstrated normal fluorine 18-fluorodeoxyglucose (FDG) uptake after surgical resection,who were managed with no further therapy.All the 13 patients were followed up for median 14 (5-38) months,and all in complete remission.Combination chemotherapy was given to 8(38.1％) patients.Three patients in stage Ⅰ E treated with COP (cyclophosphamide,vineristine and prednisone) or CHOP (cyclophosphamide,adriamycin,vincristine and prednisone) were all in partial remission.Five patients in stage ⅣE were treated with COP/CHOP in combination with rituximab,and all in complete remission.The 3-year overall survival rate and disease-free survival rate in the total patients were 100.0％ and 74.9％ respectively.Conclusions The patients with OAML generally have localized disease,show indolent clinical course,and present low lymphoma-related mortality.Surgical resection is a very important treatment in the patients with local disease.Systemic chemotherapy should be considered in patients at advanced stages.Rituximab in combination with chemotherapy can improve the remission rate.

Objective To study the effect and possible mechanism of diazoxide on myocardial ischemia/reperfusion (I/R) injury in diabetic rats, and the influence of insulin intervention which aims to maintain blood sugar levels within the normal range on the protective function of cardiomyocytes. Methods 126 health male Sprague-Dawley (SD) rats were intraperitoneally injected with one dose of 60 mg/kg streptozotocin (STZ) to reproduce diabetic model. The diabetic rats were randomly divided into seven groups, with 18 rats in each group. Myocardial I/R model was established by 30 minutes ligation of the left anterior descending branch of the coronary artery, and 120 minutes blood circulation recover. Sham group was only threaded without ligation. Rats in I/R group, diazoxide group (DZ group), and Ottawa vine penicillin (WNT) group were infused intravenously with 2 mL of 0.1% dimethyl sulphoxide (DMSO), DZ (7 mg/kg), and WNT (15 μg/kg), respectively, after 25 minutes of ischemia. Sham group was only injected with 2 mL of 0.1% DMSO. DZ+WNT group was infused with WNT 5 minutes before the injection of DZ. Insulin intervention (RI) group received a continuous insulin infusion to maintain the blood sugar at the level of 4-6 mmol/L. RI+DZ group was infused with DZ after ischemia for 25 minutes based on blood sugar control. Hemodynamic parameters in each group were monitored continuously. The pathological changes of myocardium were observed with hematoxylin and eosin (HE) staining. The expressions of phosphorylated protein kinase B (p-Akt) and phosphorylated glycogen synthase kinase-3β (p-GSK-3β) were determined by Western Blot. Results Compared with sham group, the cardiac functions of the intervention groups were significantly decreased, and severe myocardial injury was observed. Compared with I/R group, the cardiac functions of intervention groups were not obviously improved. However, after insulin intervention by which blood sugar was maintained within normal range, the cardiac function and myocardial injury were further aggravated. Compared with sham group (the expression value of sham group was set as 1), the expressions of p-Akt in other groups including I/R group, DZ group, RI group, and RI+DZ group showed no statistically significant difference (gray value: 1.07±0.09, 1.03±0.07, 1.07±0.07, 1.02±0.08 vs. 1.00, all P > 0.05). However, the expressions of p-Akt were decreased in WNT group and DZ+WNT group as compared with those of sham group and I/R group (gray value: 0.54±0.06, 0.51±0.05 vs. 1.00 and 1.07±0.09, all P < 0.05). The expressions of p-GSK-3βshowed no statistically significant difference in I/R group, DZ group, WNT group, and DZ+WNT group as compared with sham group (gray value: 0.97±0.08, 1.00±0.11, 0.98±0.06, 0.97±0.09 vs. 1.00, all P > 0.05). However, the expression of pGSK-3β was increased in RI group, RI+DZ group as compared with sham group and I/R group (gray value: 1.68±0.08, 1.70±0.05 vs. 1.00 and 0.97±0.08, all P < 0.05), and it was significantly higher in RI+DZ group than that of DZ group (gray value: 1.70±0.05 vs. 1.00±0.11, P < 0.05). Conclusions Diazoxide after myocardial injury could not protect the myocardium from I/R injury in diabetic rats, and did not trigger the activation of the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway. Insulin intervention by which blood sugar was maintaine d within the normal range exacerbates myocardial I/R injury in diabetic rats.

Objective:To observe the influence of commonly used dental cast metal posts and cores on magnetic resonance imaging (MRI)for head and neck.Methods:Six kinds of posts and cores made of metal alloy (Ni-Cr alloy,Co-Cr alloy,titanium alloy,pure titanium,Pd-Au alloy and Au-Pt alloy)were respectively fixed on the mucosa of left palate of a volunteer.The maxillofacial region of the subjects was scanned by routine head sequences SE-T1WI and TSE-T2WI respectively.Results:ANOVA of factorial design analy-sis indicated significant differences of artifacts among metal materials(F=153.63,P<0.05),scanning sequences(F=70.94,P<0.05)and the number of cast posts and cores(F=102.73,P<0.05).In both sequences the size of metal artifacts were as following:Pd -Au alloy>Co-Cr alloy>Ni-Cr alloy>Au-Pt alloy>titanium alloy>pure titanium;two posts and cores>one post and core;SE-T1WI>TSE-T2WI.Conclusion:Different cast metal posts and cores have different influences on MRI artifact.Reasonably choosing the metal materials and scanning sequences can minimize artifacts on MRI.

Objective To investigate hospital staffs' appraisals on public hospitals reform.Methods 890 medical staffs were randomly investigated by questionnaire,to learn their comments on the implementation of reform measures,public-benefit nature and reform outcomes of the reform,as well as problems found with the government and improvement suggestions,and difficulties encountered in such a reform.Results The hospital staffs' appraisals on the reform tend to be low,as 36.4％ of them hold that the reform is less effective in its outcomes or a mere formality (19.8％).The staff blamed the lack of system breakthrough (67.9％),lack of financial support (61.1％),and insufficient support from the doctors as stakeholders (49.1 ％),for most of the problems of the reform.Conclusion It is suggested to win over support of the medical staff for the reform; to improve the laws and policies related to the reform; and to establish an effective supervision system for public hospitals.

Objective To explore the clinical significance of STING in peripheral blood in patients with primary biliary cirrho-sis.Methods Admitted 28 PBC patients hospitalized in Shanghai Changhai Hospital and Shanghai Changzheng Hospital from January 2014 to October 2015.Also enrolled 28 healthy controls.Baseline data and laboratory indicators were extrac-ted,and STING mRNA expression was determined using q-PCR.The correlation between STING and clinical parameters were analyzed.The changes of STING mRNA in 5 followed-up patients with PBC were analyzed.Results Compared with healthy controls,STING mRNA was significantly increased in PBC patients and was increased in patients with severer dis-ease stages (U=0.00,P<0.05).STING was positively correlated with Mayo risk and GGT (R=0.45,R=0.42,P<0.05),and not AST,ALT or ALP (R=0.33,0.21,0.27,P>0.05).After therapy,STING mRNA were significantly re-duced in 5 PBC patients (U=0.00,P<0.05).Conclusion STING may be involved in PBC pathogenesis.
