Objective To explore the impact of the systematic social skills training on recovery of in -patients with chronic schizophrenia.Methods A total of 78 cases of long -term hospitalized patients with chronic schizophrenia were randomly divided into intervention group and control group on the basis of random number table. The two groups received psychiatric routine therapy and nursing,and general entertainment therapy,and the patients in the intervention group received group social skills training for 12 weeks.IPROS and SSSI were respectively used to evaluate two groups before the intervention,trained for 12 weeks.Results After 12 weeks'of systematic social skills training,social function defect levels SSSI score in the intervention group was apparently higher than that in the control group,and the difference was significant (χ2 =8.952,P <0.05 ).Compared with the control group (19.4 ± 4.5)points,(16.5 ±4.7 )points,(13.6 ±4.1 )points,(5.5 ±3.1 )points,(18.2 ±4.2 )points,(73.2 ± 16.3)points,in the intervention group public medical situation (10.3 ±5.5)points,life ability(12.1 ±5.7)points, social ability(6.2 ±3.5)points,antiseptic ability (3.3 ±3.3)points,concern and interest (9.6 ±4.5)points as well as the total score of IPROS (44.6 ±20.4),the differences were significant(t =7.760,6,188,8.165,2.568, 6.632,8.259,all P <0.05).Compared with before intervention,each factor in IPROS and the total score in the inter-vention group had statistically significant differences (t =8.890,7.923,8.321,3.195,8.21,9.852,all P <0.01). Conclusion The systematic social skills training can greatly promote the recovery of in -patients with chronic schiz-ophrenia,improve their social skills and life qualities.Compared with control group,the social function of patients in the intervention group has recovered positively.

OBJECTIVE:To study the affinity of penehyclidine optical isomers to muscarinic(M)receptor subtypes,and pro-vide reference for revealing the action targets and efficacy selectivity of penehyclidine. METHODS:Homology modeling,molecu-lar docking and other molecular simulation technologies were used to analyze and predict the binding energy of 4 optical isomers to M receptor subtypes and judge its affinity by comparing the binding energy of different optical isomers R1 (3R,2′R),R2 (3R, 2′S),S1(3S,2′R),S2(3S,2′S)with M receptor subtypes M1-M5. RESULTS:All the 4 optical isomers can dock into the ac-tive sites of M receptor subtypes,and different optical isomers showed great differences in the molecular docking with different M receptor subtypes. Penehyclidine isomers showed larger binding energy to M3,the binding energy of 4 optical isomers ranged in 5736.519-5907.143 kcal/mol. The binding energy of R1 to M1 was 1190.041 kcal/mol;while those of other optical isomers to each receptor subtype were lower or negative. CONCLUSIONS:R1 shows the affinity to M1 receptor. And all the 4 optical isomer show the affinity to M3.

Objective To explore the impact of the systematic social skills training on recovery of chronic schizophrenia patients with negative symptom and social skills defects.Methods A total of 82 cases of long -term hospitalized patients with chronic schizophrenia were randomly divided into intervention group and control group by digital table,41 cases in each group.The two groups received psychiatric routine therapy and nursing,and general entertainment therapy,and systemic social skills training was conducted in the intervention group for 12 weeks.PANSS and SSC were respectively used to evaluate the two groups before and after the intervention.Results After 12 weeks of systematic social skills training,the total score of SSC[(24.5 ±4.5)points]in the intervention group was apparently lower than that in the control group[(29.2 ±5.2)points],and the difference was statistically significant(t =3.212, P <0.01).Compared with the control group[(20.5 ±4.3)points,(27.2 ±4.2)points,(59.1 ±9.5)points],in the intervention group the score of negative symptom mental pathology and total score of PANSS were (14.9 ± 3.7)points,(24.5 ±3.5)points,(52.8 ±7.1)points.The differences of total score between the two groups were sta-tistically significant(t =5.199,3.317,3.239,all P <0.01),while the positive symptoms score was not statistically significant(P >0.05).Compared with before intervention,in the negative symptom table,the differences of total score N2,N3,N4,N6 had statistically significant differences(t =4.533,5.413,4.501,4.668,all P <0.01).Conclusion The systematic social skills training can greatly promote chronic schizophrenia patients with negative symptom and social skills defects,improve their social skills and life qualities.

Objective To explore the effects of signaling pathways inducing activation of DC-SIGN promoter on the activity of HIV-1 5'LTR.Methods The sequences of DC-SIGN promoter and HIV-1 5'LTR were amplified by PCR and then cloned into pGL-3/Basic plasmid to constructluciferase reporter plasmids for DC-SIGN promoter and HIV-1 5'LTR.Differentiated THP-1 cells stimulated by PMA (phorbol myristate acetate) were used as the in vitro model of DCs.The activaties of DC-SIGN promoter and HIV-1 5'LTR induced by IL-4 in differentiated THP-1 cells were studied using luciferase reporter plasmids.The signaling pathways were identified by using specific inhibitors.Results IL-4 induced signaling pathways could increase the activities of HIV-1 5'LTR and DC-SIGN promoter for more than two times in THP-1 cells transfected with luciferase reporter plasmids.However,the activity of HIV-1 5'LTR was weaker than that of DCSIGN promoter.ERK/JAK-STAT/NF-κB signal pathway blockers could inhibit the luciferase activity driven by DC-SIGN promoter,of which ERKI/2 blocker showed the strongest inhibitory effect that almost completely blocked IL-4 induction.NF-κB blocker had a significant inhibitory effect on HIV-1 5'LTR activity at a rate of 52.32％,followed by the ERK blocker at a rate of 43.31％.Conclusion This study suggested that IL-4-induced signaling pathways mediate the activation of DC-SIGN promoter and HIV-1 5'LTR through NFκB and ERK.

Objective To investigate the protective effect of GuanXinShiWeiWan on ischemia reperfusion(I-R) injury rat.Methods 50 Wistar rats were randomly divided into normal group, model group, GuanXinShiWeiWan low ( 0.3 mg/kg ) and high ( 0.9 mg/kg ) dose group and positive group, each had 10 rats.Adopting the model of ischemia reperfusion injury of isolated rat hearts, the contents of SOD,MDA,LDH,CK and Ca2 +-ATP, Ca2 +-Mg2 +-ATP, Na +-K +-ATP in cardiac muscle tissue were tested and compared.Results Compared with model group, GuanXinShiWeiWan significantly improved the activities of SOD、Ca2 +-ATP,Ca2 +-Mg2 +-ATP and Na +-K +-ATP (P<0.05 or P<0.01) in cardiac muscle tissue which injured by ischemia reperfusion, while reducing markedly the contents of MDA,LDH,CK(P<0.05 or P<0.01).Conclusion GuanXinShiWeiWan can profect the cardiac muscle of ischemia reperfusion.

Background To investigate the expression of the early growth response gene-1 ( Egr-1 ) mRNA after focal cerebral ischemia / reperfusion in rats.Methods Ten healthy male SD rats weighing 200 ～ 250 g were used to create model of focal cerebral ischemia. The expression of Egr-1 after focal cerebral ischemia/reperfusion in rats was determined using in situ hybridization and RT-PCR.Results (1) The result of the in situ hybridization: A trace amount of Egr-1 mRNA expressed in the neurons and the glial cells in the sham operated group. The expression of Egr-1 mRNA at the ischemic side increased dramatically following ischemia and reached peaks after 4 hours' reperfusion. Egr-1 expression started to subside following 22 hours' reperfusion and further decreased following 166 hours' reperfusion, which was still significantly higher than that in the sham operated group. (2) The result of RT-PCR: The expression of Egr-1 mRNA at the ischemic side was significantly higher than that in the sham operated group at all time points after ischemia/reperfusion in the rats(P ＜0. 01). Expression of Egr-1 increased 2 h after ischemia and reached the peak 4 h following reperfusion, and then decreased dramatically at 46 h after reperfusion which was still higher than that in the sham operated group (P ＜ 0. 01). As the ischemia/reperfusion period prolonged, the expression of Egr-1 mRNA increased gradually, but still detectable even 166 h following reperfusion. The expression of Egr-1 was significantly higher than that in the sham operated group at all time points (P ＜0. 01).Conclusions The expression of Egr-1 mRNA increase in the neurons and the glial cells after ischemia/reperfusion, which may have protective effects on ischemic brain tissues.
