Objective To investigate the properties of the abilities of spontaneous counterfactual thinking(SCFT) and induced counterfactual thinking(ICFT) produced by undergraduate students with depressive symptoms.Methods Undergraduates were induced to produce SCFT after recalling a negative event and ICFT after reading a story about a traffic event.Then the undergraduates were demanded to complete the counterfactual inference test(CIT).The amount and rationality of CFT and the scores of CIT were analyzed.Results Mild depressive students(MDS) generated a higher amount of SCFT than non-depressive students(NDS),midrange depressive students and severe depressive students(SVDS)(P0.05).The rationality of SCFT generated by four groups were significantly different(P

Aim To study the effects of telmisartan upon serum calcineurin.Methods 92 male SD rats with the same age were randomly divided into control group (N), sham operation group (S), 2K1C+distilled water group (K) and 2K1C+telmisartan group (T).S rats were performed the open-abdomen surgery without being restricted any renal artery, but the K and the T rats were restricted their left renal artery. Beginning from the third week after the surgery, the K rats started to be treated with the intragastric infusion of distilled water 10 ml·(kg·d)~(-1) , while the T rats with telmisartan 10 mg·(kg·d)~(-1) .And after being treated for 2, 4 and 8 weeks, rats were respectively measured the systolic blood pressure (SBP), the diastolic blood pressure (DBP) of the abdominal aorta. Before and after the operation, ultrasonography with probe of 7.5 MHz was used to obtain the structure and functional indexes, such as IVSd, IVSs, LVPWd, and serum calcineurin were evaluated by ELISA and colorimetric assay kit.Result Compared with the S group and the N group, ① the results of blood pressure (SBP, DBP) were significantly higher in K group (all P <0.01), after use of telmisartan, blood pressure was significantly reduced(P <0.01);② the thickness of interventricular septal and left ventricular posterior wall at the end of diastolic and systolic were significantly higher in K group (all P <0.01), after use of telmisartan, the thickness of those declined(all P <0.01);③ the level and activity of serum calcineurin were significantly higher in K group (all P <0.01), after use of telmisartan, the level and activity of calcineurin significantly fell(P <0.01).Conclusion The serum calcineurin of artery was also raised in the left ventricular remodeling. Telmisartan ameliorates ventricular remodeling effectively, which may be associated with decreasing the expression of artery serum calcineurin.

Objective:To investigate the effects of enteral immunonutrition on the intestinal barrier function and immune function in patients with severe pneumonia.Methods:Ninety patients with severe pneumonia were randomly divided into experimental group (n =45) and control group (n =45).All patients were received conventional therapy.In addition,patients in experimental group were given enteral immunonutrition,while patients in control group were given regular enteral nutrition.The changes of general conditions,intestinal barrier function index and immune function index were determined before treatment,on day 5 and 10 after treatment.The time of invasive mechanical ventilation,APACHE Ⅱ score and clinical effects of two groups were determined on day 10 after treatment.Results:Compared with those before treatment,in both groups,body temperature,respiration,heart rate,white blood cell count were all significantly decreased on day 5 and 10 after treatment (P < 0.05).The above parameters were significantly lower in experimental group than control group on day 10 after treatment (P < 0.05).The levels of serum ET,DAO were significantly decreased on day 5 and 10 after treatment in two groups compared with those before treatment (P < 0.05),and these parameters were significantly lower in experimental group than control group(P <0.05).The number of CD3 and CD4 positive cell and the ratio of CD4 +/CD8 + were significantly increased on day 5 and 10 after treatment in two groups when compared with those before treatment (P < 0.05),and these parameters were higher in experimental group than those in control group(P < 0.05).The time of invasive mechanical ventilation,APACHE Ⅱ score were lower in experimental group than those in control group on day 10 after treatment (P < 0.05).The rate of clinical response were higher in the experimental group than that in the control group on day 10 after treatment (P < 0.05).Conclusion:Enteral immunonutrition is more effective in protecting the intestinal barrier function,improving the immune status,enhancing the immunity,reducing the time of invasive mechanical ventilation,and achieving the clinical effects of patients with severe pneumonia.

To investigate the mutation site of pathogenic gene in patients with hypertrophic cardiomyopathy (HCM) and to analyze the relationship between the genotype and clinical phenotype. Methods: Targeted exon capture sequencing was conducted in a HCM proband for 30 coding exons related HCM gene by all exon amplification and high-throughput sequencing. Furthermore, Sanger sequencing was performed in other family member and in 200 healthy volunteers for verification. The familial investigation included in clinical presentation, physical examination, electrocardiogram and echocardiography. Results: There were 3/6 blood relatives carrying cardiac myosin-binding protein gene MyBPC3 G772A heterozygous mutation, the mutation site was at 258 amino acid of MyBPC3 as glutamic acid (Glu) was substitute to lysine (Lys), such mutation was not found in rest of family member and not in healthy volunteers. The onset of proband and her daughter was rather late, they had palpitation and chest tightness; echocardiography showed interventricular septum basal segment thickening (16-18) mm. Proband was complicating paroxysmal ventricular tachycardia, malignant arrhythmia and heart failure, the maximum pressure gradient of left ventricular outflow was 56 mmHg, which with the high risk for sudden death. Conclusion: Comprehensive gene test has been helpful for clinical stratification, early diagnosis and treatment. MYBPC3 site mutation c.G772A might be the pathogenic mutation in that specific HCM family.

Objective:To investigate the effect of mannose on the radiosensitivity of six human non-small cell lung cancer cell lines and its possible mechanism.Methods:The expression of mannose phosphate isomerase in six lung cancer cell lines were detected by Western blot. The inhibitory effect of mannose on the proliferation of lung cancer cell lines were observed by MTT assay. When irradiated with 0, 2, 4, 6, 8 and 10 Gy, the effect of mannose on the radiosensitivity of six lung cancer cell lines was detected by plate clone formation assay, respectively; and the apoptosis rates of normal control, mannose, irradiation and combined groups were detected by flow cytometry.Results:The expression levels of mannose phosphate isomerase were different among six lung cancer cell lines. Among them, A549 cells had the highest expression level and H460 cells showed the lowest expression level. When aD ministrated with 11.1 mmol/L mannose, the same inhibitory effect was observed on both A549 and H460 cell lines. Moreover, the inhibitory effect on H460 cell line was significantly increased with the increase of mannose concentration. In addition, aD ministration of 11.1 mmol/L mannose could significantly increase the radiosensitivity and apoptosis rate of H460 cell line. However, it exerted limited effect upon the radiosensitivity and apoptosis rate of A549 cell line. Conclusion:In six lung cancer cell lines with high expression of mannose phosphate isomerase, the aD ministration of mannose can enhance the radiosensitivity of partial tumors cells.
