Objective To explore the efficacy of low -frequency repetitive transcranial magnetic stimulation (rTMS)and setraline in treating Parkinson's disease patients with depression.Methods 80 cases of Parkinson's dis-ease with depression were randomly divided into the study group(administered with rTMS and setraline)and the con-trol group(administered only with setraline)according to random number table,40 cases in each group.Hamilt De-pression Rating Scale(HAMD),Unified Parkinson's Disease Rating Scale(UPDRS)and Treatment Emergent Symp-toms Scale(TESS)were assessed before treatment and 1,2,4 weeks after treatment.Results The scores of HAMD and UPDRS in the study group were lower than those in the control group[the score of HAMD at 2nd week in the study group was (18.44 ±5.56 )points,the score of HAMD at 4th week in the study group was (10.51 ± 4.27)points,the score of HAMD at 2nd week in the control group was (21.23 ±5.18)points,the score of HAMD at 4th week in the control group was (14.05 ±4.10)points,t2w =-2.322,t4w =-3.782,all P <0.05],and the score of UPDRS at 2nd week in the study group was (30.14 ±4.92)points,the score of HAMD at 4th week in the study group was (28.39 ±3.38)points,the score of UPDRS at 2nd week in the control group was (33.74 ±4.87)points, the score of HAMD at 4th week in the control group was (31.09 ±3.94)points (t2w =-3.289,t4w =-3.290,all P <0.05),while the effective rate of the study group(77.5%)was significantly higher than that in the control group (45.0%)(χ2 =4.450,P <0.05 ).Conclusion The efficacy of rTMS combined with setraline for Parkinson 's disease with depression is superior to that of using setraline alone.

Objective To explore the efficacy of shugan -jieyu capsule and escitalopram in treating post -stroke depression (PSD).Methods 80 cases with PSD were randomly divided into the study group(administered with shugan -jieyu capsule and escitalopram)and the control group(administered only with escitalopram),40 cases in each group.Hamilt Depression Rating Scale(HAMD),Modified Einberg -Scandinavian Stroke Scale(MESSS)and Treatment Emergent Symptoms Scale(TESS)were used to assess treatment effect before treatment and at the weekend of 2nd,4th,8th after treatment.Results The scores of HAMD and MESSS in the study group were much lower than those in the control group.The scores of HAMD at 4th weekend and 8th weekend in the study group were (16.92 ± 3.75),(8.60 ±3.25),those in the control group were (19.27 ±4.11),(11.13 ±3.72)(t2w =-2.671,t4w =-3.239,P <0.05).The scores of MESSS at 4th weekend and 8th weekend in the study group were (20.06 ±3.87), (12.47 ±3.97),which in the control group were (21.68 ±3.12),(15.09 ±3.20)(t2w =-2.061,t4w =-3.250, P <0.05),while the effective rate in the study group(80.0%)was significantly higher than that in the control group (45.0%)(χ2 =5.227,P <0.05).Conclusion The efficacy of shugan -jieyu capsule combined with escitalopram for PSD is superior to use escitalopram alone.

Objective To explore effects of shuanghuanglian combined with levofloxacin on antibiotic resistance of Staphylococcus Aureus ATCC29213 to levofloxacin. Methods Tissue cage infection model with Staphylococcus aureus was established in rabbits, and the infected animals were given with levofloxacin alone ( group A ) or in combination with shuanghuanglian ( group B) for 5 days respectively. Steady-state concentration of levofloxacin in tissue cage, bacteria recovery and bacterial resistance in tissue cage infection model were studied. Results Steady-state concentration of levofloxacin in tissue cage was not significantly different between group A and group B. The recovery rate of bacteria was significantly lower in group B than in group A (20. 0% vs. 100. 0%). The minimum inhibitory concentration (MIC) was lower in group B than in group A. Conclusion Shuanghuanglian combined with levofloxacin is helpful to reduce antibiotic resistance of Staphylococcus aureus to levofloxacin, indicating that some Chinese traditional medicine combined with antibiotics can reduce antibiotic resistance.

Objective To observe the effects of red blood cell lysis buffer on the isolation and culture of human bone marrow mesenchymal stem cells (hMSCs) in vitro.Methods Twenty-two bone marrow samples were randomly divided into 2 groups,including 11 samples of crushed red blood cell prepared with Tris-NH4Cl red blood cell lysis agent and 11 samples prepared without red blood cell lysis agent.The intervals from primary generation to 1,2 and 3 passages and the time of expansion to l07 cells were compared between the two groups.Results The times for P1,P2 and P3 passage was ( 9.3 ± 4.9 ) days vs.( 7.2 ± 1.0 ) days,( 14.4 ±4.7) days vs.( 14.5 ± 3.5 ) days,and ( 18.5 ± 5.0 ) days vs,( 20.1 ± 4.4 ) days,respectively,in crushed red blood cell group and non-crushed red blood cell group.The differences were not significant ( t =1.39,t =0.06,t =0.80,P ＞ O.05 ).The time for expansion to 107 cells in two groups was not significantly different ( t =0.80,P ＞0.05).Conclusion Tris-NH4Cl agent in red blood cell lysis has no significant effects on hMSCs isolation,culture and cell proliferation,which indicates erythrocyte lysing may be not an independent step for hMSCs isolation and expansion in vitro.

Abstract: Neurotensin receptor-1 (NTR1), which can stimulate the intracellular cascade signal pathway, belongs to the large superfamily of G-protein coupled receptors. NTR1 is related to the occurrence and development of several kinds of diseases. In order to screen the inhibitors for the cancers associated with NTR1 protein, we established a CHO (Chinese hamster ovary) cell line in which human neurotensin receptor-1 was highly expressed. The method is to construct the recombinant plasmid which was lysed with the hNTR1 gene and transfect it into CHO cells. After selected with G418, the cell line was evaluated by Western blotting analysis and calcium flux assays. Through the calcium flux assays on FlexStation 3, we got the EC50 value of neurotensin peptide which is the natural NTR1 agonist, and the IC 50 value of SR48692 which is the known NTR1 antagonist. The established human CHO/NTR1 cell line can be used to study the profile of NTR1 biological activity and further screen of NTR1 antagonists and agonists.

Objective To explore the effect of prevention and treatment on steroid-induced osteonecrosis of mice femoral head(ONFH) treated with metformin. Methods Thirty-six Kunming mice were randomly divided into three groups (n = 12):A (Control Group), B (Model Group)and C (Prevention Group). For producing ONFH mice models, did the intraperitoneal injection of horse serum (10 mL/kg) to B and C firstly. After two weeks, continuing the intraperitoneal injection of horse serum (5 mL/kg) again with the prednisolone intramuscularly [45 mL/(kg· day), totally for 5 days]. Meanwhile, feeding normal saline 10 mL/(kg·day) to B and feeding metformin hydrochloride [0.2 g/(kg·day)] to C. For A, mice were only given normal saline intramuscularly and intragastrically in equal quantity at the same time. The contents of serum cholesterol (TC), triglycerid (TG), plasma von willebrand factor (VWF) and plasminogen activator inhibitor 1 (PAI-1) were determined at the 2nd, 4th and 6th week after treatment. The micewere sacrificed at 2nd, 4th, and 6th weekafter treatment, and femoral heads were harvested to do histopathology analysis. Results The appearance and shape of the femoral head and the surface of cartilages were normal. The percentage of empty osteocyte lacunae in B was significantly higher than that in C (P < 0.05), there was no significant difference between A and C (P>0.05). TC and TG contents in C were significantly lower than that in B in 2th、4th、6th weeek(P<0.05), and higher than that in A(P<0.05). VWF and PAI-1 level in C were significantly lower than that in B at 2nd and 4th week (P<0.05), but there were no statistical significance at 6th week. there were no statistical significance for the comparison between A and C. Conclusion Metformin can prevent steroid-induced ONFH by improving hyperlipemia, hypercoagulability and hypofibrinolysis, then effectively prevent osteonecrosis.

Objective To research the resilience and influencing factors of the plateau soldiers.Methods Resilience Scale for Adult (RSA),Symptom Checklist (SCL-90),Eysenck Personality Questionnaire (EPQ) and General Self-Efficacy Scale (GSES) was used in this study to 756 plateau soldiers.Results ①The high resilience has been found in plateau soldiers (2.78 ± 0.47 ).There were significantly differences in three education levels of the plateau soldiers in planned of future (F =3.261,P =0.039 ),family cohesion (F =6.428,P =0.002 ),structure style(F=4.135,P=0.016) and RSA scores(F=4.162,P=0.016),and college ＞ senior high school ＞ junior high school.②Compared to the lower group in the RSA,the higher group scored significantly higher in extraversion ( t =13.004,P =0.000) and self-efficacy ( t =12.956,P =0.000 ),while lower in SCL-90 ( t =10.308,P =0.000) and neuroticism( t =11.297,P =0.000).③Resilience had significantly positive relation with self-efficacy ( r =0.48 ) and extraversion ( r =0.46 ),and negative relation with neuroticism ( r =- 0.42 ) andSCL-90( r =-0.41 ).The self-efficacy extraversion and neuroticism have nice predictive ability (42％).Conclusion The Resilience of plateau soldiers are good condition,self-efficacy,extraversion,and neuroticism are important influencing factors for plateau soldiers.
