Objective To explore the executive function and working memory ability of patients with social phobia. Methods The study included 42 social phobia patients whose age, sex, and level of education were matched with those of a healthy control group. Wisconsin Card Sorting Test and Digit Span, Spatial Span, Multiple-Objects-Spatial span were used to study the executive function and working memory. Results Patients with social phobia scored higher than the control group in terms of the number of non perseverative errors on the Wisconsin Card Sorting Test ( 18. 75 ± 6. 20, 8. 89 ± 3. 22 respectively ). No differences were observed in perseverative errors and other scores between the patient and control group. Patients with social phobia scored lower than the control group in terms of Digit Span(7.25 ±1.35,8.03 ±2. 30 respectively) ,Spatial Span(6. 11±1.85,8.61 ±2.87 respectively) and Multiple-Objects-Spatial span(4.03 ± 1. 39 ,5. 18 ± 1.07 respectively). Conclusion Working memory ability in the social phobia patients is impaired, and this may cause the poor performance in patients with the social phobia in academic and social working.

ObjectiveTo explore the influence of clinical symptoms and applicability of discontiguous naikan cognitive therapy(DNCT) among convalescent schizophrenic patients.MethodsApplying DNCT,100 convalescent paranoid schizophrenic patients with convalescent clinical state were consecutively recruited.All the patients were randomly divided into DNCT group and control group and were pretreated with antipsychotic agent therapy,40 patients in DNCT group and 49 patients in control group entered the statistic analysis,11 lost.In DNCT group,the patients received DNCT for successive 28 days.In control group,the patients only received antipsychotic agent therapy.Positive and Negative Syndrome Scale (PANSS),Nurses'Observation Scale for Inpatient Evaluation (NOSIE) were administered to all subjects pre- and post-treatment.ResultsAfter treatment,in the study group,total PANSS scales ( (54.00 ± 10.19 ) vs (45.05 ± 5.28 ),t =5.430,P ＜ 0.01 ),the positive symptom item ((11.00±3.33) vs (9.53 ±1.85),t=3.670,P=0.01),negative symptoms item((12.15 ±4.38) vs (9.40± 2.15 ),t =4.371,P ＜ 0.01 ),general psychopathology item ( (26.90 ± 5.66) vs (22.65 ± 3.07 ) 分,t =4.494,P＜0.01 ) scored lower than before,The difference was statistically significant.PANSS study group after treatment,total scores( (45.05 ±5.28 ) vs (52.04 ± 10.36),t=-3.876 P＜0.01 ),negative symptom item score( t =- 3.789,P ＜ 0.01 ),composite item ( t =2.251,P =0.027 ),the general psychopathology item ( t =- 3.336,P =0.01 ),score significantly lower than the control group.After twelve weeks follow-up study,in the study group,PANSS total scores ( t =4.764,P ＜ 0.01 ),item score of positive symptoms ( t =2.335,P =0.025 ),negative symptoms item score( t =3.083,P =0.004) ),genial psychopathology item score ( t =4.325,P ＜ 0.01 ) was still significantly lower than before treatment,the difference was statistically significant.In study group,after treatment,NOSIE Scale total negative factors scores( t =3.083,P =0.004) were significantly lower than before,total positive factors( t =-2.446,P=0.019),the total estimated factor in the disease scores ( t =-4.730,P ＜ 0.001 )were significantly higher than before treatment.After treatment,in the study group,negative factors ( t =-3.953,P=0.000) were significantly lower than the control group,twelve weeks follow-up,study group total negative factors of NOSIE scale score( t =2.126,P =0.040) was still lower than before treatment,the difference was statistically significant,total positive factor( t =- 2.054,P =0.047 ) still higher than before treatment,the difference was statistically significant.ConclusionDNCT can possibly improve part clinical symptoms of patients with convalescent schizophrenia to a certain extent,especially negative symptom,and the impact remained to the twelve weeks,but need to further prove the effect of naikan cognitive therapy.

Objective To explore the difference of the oxytocin levels between social phobia patients and normal controls,and the relationship of symptoms severity of social phobia with the oxytocin levels and the relationship of drug effects with oxytocin levels.Methods Twenty seven 16-26 years old social phobia patients and thirty one normal controls were tested by an enzyme-linked immunosorbent assay to evaluate the oxytocin levels,and the Liebowitz Social Anxiety Scale was used to evaluate the symptoms severity of social phobia in patient group.Paroxetine was used to treat the patients with the drugs of 20mg per day,the Clinical Global Impression Scale were used to evaluate the drug effects after 4 weeks treatment.Results Mann-Whitney test showed there were significantly differences in oxytocin level between patients and controls ( (202.93 ± 145.06) pg/ml vs ( 152.29 ± 101.89 ) pg/ml,Z =- 1.307,P=0.030).Multiple liner regression analyses showed that the level of oxytocin was an impact factor of the severity of social phobia symptom (adjusted R2 =0.158,F=5.888,P=0.023 ).Logistic regression analyses showed that the level of oxytocin was an impact factor of the effective of drug treatment( OR=3.132,P =0.029 ).Conclusion This study indicate that the value of plasma oxytocin maybe significantly differences between social phobia and normal controls and the plasma oxytocin level maybe a factor which influence the symptoms severity and the effective of drug treatment in social phobia patients.

Objective:To explore the regulatory effect of glutathione S-transferase P1(GSTP1) on the radiosensitivity of mouse Lewis lung cancer (LLC) cells.Methods:GSTP1-shRNA lentivirus and negative control lentivirus were used to respectively infect the LLC cells, and stable transgenic strains were selected. Real-time PCR and Western blot were conducted to quantitatively measure the expression levels of GSTP1 mRNA and protein in the LLC cells to verify the knockdown effect. The cell counting kit-8(CCK-8) assay was used to detect cell viability after irradiation. The colony formation assay was utilized to assess the cell proliferation ability after irradiation. Flow cytometry was performed to assess the level of cell apoptosis after irradiation. The tumor-bearing mice were established and irradiated to detect the changes in the tumor volume after irradiation. TUNEL staining was employed to detect the level of tumor apoptosis after irradiation. Immunofluorescence was used to detect the number of CD 4+ CD 8+ T cells in the tumor after irradiation. Results:Real-time PCR and Western blot showed that after shRNA lentivirus interference, the expression levels of GSTP1 mRNA and protein were significantly down-regulated. Down-regulation of GSTP1 reduced cell viability and proliferation, and increased the rate of cell apoptosis after irradiation. The tumor volume of the tumor-bearing mice after irradiation in the GSTP1 knockdown group was significantly smaller than that in the NC group, whereas the tumor apoptosis rate was significantly higher and the number of infiltrating CD 4+ CD 8+ T cells in the tumor was remarkably higher compared with those in the control group. Conclusion:Knockdown of GSTP1 can significantly increase the radiosensitivity of LLC cells and enhance the infiltration of lymphocytes in tumor tissues.

ObjectiveTo explore the evolution principles of symptoms including deficiency， phlegm and blood stasis， and of the functional near-infrared spectroscopy （fNIRS） cerebral hemodynamic characteristics at various stages in patients of Alzheimer's disease. MethodsA total of 497 patients with complaint of memory loss were included， and were divided into subjective cognitive decline （SCD） group （198 participants）， mild cognitive impairment （MCI） group （228 participants） and dementia （AD） group （71 participants）. Neuropsychological evaluation， traditional Chinese medicine （TCM） syndrome investigation， and fNIRS data collection of prefrontal cortex were performed in each group. Descriptive statistics were used to analyze the distribution of TCM syndromes and the difference of TCM syndrome scores in each group； logistic regression was used to analyze the influence of TCM syndromes on the incidence of the patients； association rules were used to analyze the TCM syndromes of the patients； the hemodynamic characteristics of fNIRS in the prefrontal cortex of each group were compared. ResultsKidney essence deficiency syndrome was the dominant syndrome in all stages of AD. There were statistically significant differences in the distribution frequency of kidney essence deficiency， phlegm turbidity obstructing orifices， blood stasis obstructing collaterals， qi and blood deficiency， heat toxin in the interior， and fu-organ stagnation and turbidity retention syndromes among the three groups （P＜0.01）， and the scores of kidney essence deficiency syndrome among the three groups were statistically significant （P＜0.01）. Logistic regression analysis showed that kidney essence deficiency， and qi and blood deficiency syndromes were the main risk factors for the SCD group （P＜0.05）， phlegm turbidity obstructing orifices syndrome was the main risk factor for the MCI group （P＜0.05）， and heat toxin in the interior， and fu-organ stagnation and turbidity retention syndromes were the main risk factors for the AD group （P＜0.05）. The association rule analysis showed that the combination of kidney essence deficiency plus phlegm turbidity obstructing orifices had the highest support （33.33%） in the SCD group， and the combination of kidney essence deficiency plus blood stasis obstructing collaterals had the highest support （32.90% and 52.13%） in both the MCI and AD group. The prefrontal fNIRS results showed that the mean ∆HbO₂ concentration in the left dorsolateral prefrontal cortex （LDLPFC） decreased sequentially among the three groups （P＜0.05）， and the mean ∆HbO₂ concentration in the LDLPFC was negatively correlated with the MoCA score among the three groups （r = -0.142， P＜0.05）. Further analysis showed that the mean ∆HbO₂ concentration in the LDLPFC of patients with kidney essence deficiency syndrome were statistically significant differences among the three groups （P＜0.05）. ConclusionKidney deficiency is the basis of the pathogenesis of AD， and the key brain area damaged is the LDLPFC. Turbid pathogens such as phlegm and blood stasis are the pathological factors that aggravate the disease， and the syndromes of AD show the evolution law of deficiency and excess as “kidney deficiency→phlegm turbidity→blood stasis→turbid toxin”. The changes in prefrontal hemodynamics based on fNIRS are consistent with the changes in the characteristics of symptoms， which can be used to assess the degree of cognitive impairment in AD patients.
