Post-stroke infection mainly includes stroke-associated pneumonia and urinary tract infection.It is one of the major causes of increasing disability and mortality in patients with stroke.Its occurrence and development is associated with the basal state,stroke location,infarct volume,severity,dysphasia,aphasia and other factors of the whole body system in patients with stroke.In recent years,stroke-induced immunosuppression is receiving increasing attention.

Objective To observe the intervention effect of Wuxing-Jiangu exercise for different syndrome types of elderly patients with chronic low back pain.Methods A total of 199 patients who met the criteria of chronic low back pain (CLBP) were divided into a Wuxing-Jiangu exercise group (86 cases), a control group (85 cases) and a health education group (28 cases). On the basis of health education, theWuxing-Jiangu exercise group was given Wuxing-Jiangu exercise; the control group was treated with the warm type frequency therapeutic instrument; health education group was only given health education guide. The changes of the score of CLBP patients before and after treatment with different syndrome types were observed.Results After 3 months of treatment, the score of the kidney deficiency syndrome and spleen deficiency syndrome in the Wuxing-Jiangu exercise group, the control group and the health education group had significant differences (H were12.554, 8.014, respectively;all P<0.01); After 3 months of treatment, the score of kidney deficiency syndrome and spleen deficiency syndrome in the Wuxing-Jiangu exercise group reduced than before the treatment (Z were -5.975,-5.025, respectively)and 1 month after the treatment(Z were -5.976,-5.026, respectively) (all P<0.01).Conclusion Wuxing-Jiangu exercise can reduce the score of the kidney deficiency syndrome and spleen deficiency syndrome and improve clinical syndrome.

Objective To discuss the advance and experience of postoperative management in multivisceral transplantation(MVT).Methods Five patients with abdominal multiple organs malig- nances were subjected to multivisceral transplantation.The excised specimens included the liver,pan- creas,duodenum,stomach,spleen,mesentery and all of the involved lymph nodes.The transplanted organs were liver,pancreas,duodenum and parts of intestine.Patients were monitored and sustained stably in breath,hemodynamics and homoeostasis.The coagulation was also monitored and kept in balance.The intensive immunosuppressive protocol,including steroid,tacrolimus,mycophenolate mofetil and Zenapax,was used to prevent the acute rejection.The endocrine and exocrine of pancreas were tested,color Doppler examination was done every day,and Somatostatin was used to prevent pancreatitis.Drugs to bacteria,fungus and virus infection were prophylactically used.Results All patients waked up with 4-6 h after operation and began recovering with 3-7 days.Dynamic examina- tions revealed that the functions of grafted liver,pancreas and duodenum were satisfactory.No com- plications of acute rejection,pancreatitis,bleeding and thrombosis occurred.Conclusion Many ques- tions in postoperative management related to multivisceral transplantation are devoted to study.Nice experience of management to organ transplantation,detailed monitoring and prophylactically medica- tions are safeguards to steady recovering and further prognosis.

BACKGROUND: Results from clinical trials suggested that clopidogrel and ticlopidine had side effects of granulopenia, and aspirin could inhibit endothelial progenitor cell proliferation. There is no report of effects of these drugs on human bone marrow mesenchymal stem cells (hBMSCs) in stem cell transplantation. OBJECTIVE: To investigate the effects of antiplatelet drugs including clopidogrel, ticlopidine and aspirin on hBMSC proliferation and secretion. DESIGN, TIME AND SETTING: The cytology in vitro observation was performed at the Laboratory of Toxicology, Shanghai Municipal Center for Disease Control and Prevention from March to December 2006.MATERIALS: The second passage of hBMSCs was kindly donated from Shanghai Tissue Engineering Research & Development Center, Shanghai Ninth People's Hospital. Clopidogrel (Lot number J20040006) and ticlopidine (Lot number H19980186) were obtained from Hangzhou Sanofi-Synthelabo Minsheng Pharmaceutical CO., Ltd. Aspirin (Lot number 20050059) was obtained from Bayer Vital GmbH. METHODS: The standard culture medium consisted of DMEM-LG, 10% heat-inactivated FBS, 100 U/mL penicillin and 100 μg/mL streptomycin. After being cultured in vitro expanded out to passage 6, hBMSCs were treated with antiplatelet drugs of different concentrations and compared with control group. MAIN OUTCOME MEASURES: Cell proliferation was assessed by 3- (4, 5-dimethylthiazol -2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay, level of vascular endothelial growth factor (VEGF) of culture medium was detected by enzyme-linked immunoadsordent assay (ELISA), and surface antigens of hBMSCs were analyzed by the flow cytometry. RESULTS: A570 values of hBMSCs treated by clopidogrel or ticlopidine of 0.02,0.1,0.4,2,10,40 μmol/L were higher than control group (P < 0.01), while A570 values of aspirin group of 60, 600, 2 000 μmol/L were lower than control group(P < 0.05). Antiplatelet drugs had no obvious effect on cell surface antigens(CD34, CD105, CD106)expressed by hBMSCs. Treated by high dose clopidogrel or ticlopidine (40 μmol/L), VEGF level from hMSCs was lower than that of control group(P < 0.01), but VEGF level of low dose (0.02 μmol/L) ticlopidine group was higher than control group(P < 0.01), and there was no significantly difference of VEGF level among low dose clopidogrel group (0.02 μmol/L), aspirin group (5, 2 000 μmol/L), and control group(P > 0.05). CONCLUSION: Clopidogrel and ticlopidine improve proliferation of hBMSCs, but aspirin inhibits proliferation of hBMSCs. High dose of clopidogrel and ticlopidine suppress VEGF secretion of hBMSCs, while low dose of ticlopidine promote it. Antiplatelet drugs have no obvious effect on hBMSCs differentiation.

Objective To investigate the resting-state functional connectivity of the two hemispheres between multiple system atrophy (Parkinsonian type,MSA-P) and Parkinson's disease (PD).Methods A total of 25 MSA-P,29 PD patients and 29 well-matched healthy controls recruited in the Nanjing Brain Hospital Affiliated to Nanjing Medical University from June 2013 to December 2015 were scanned with resting-state functional magnetic resonance imaging for voxel mirrored homotopic correlation (VMHC) analysis.The Mini Mental State Examination,Montreal Cognitive Assessment,Frontal Assessment Battery and Unified Parkinson's Disease Rating Scale-Ⅲ (UPDRS-Ⅲ) were used to assess the clinical symptom.Then the relationship between the change of VMHC values and severity of clinical symptoms was investigated.Results Compared with healthy controls,MSA-P and PD patients both showed decreased VMHC in bilateral cerebellum posterior lobe,precuneus gyrus,middle temporal gyrus,and postcentral gyrus.Compared with PD or healthy controls,MSA-P patients exhibited lower VMHC in bilateral putamen.Significant negative correlation between VMHC values of putamen and UPDRS-Ⅲ scores was found in MSAP patients (r =-0.607,P =0.001).Conclusion These functional changes suggest that the abnormal interhemispheric synchrony probably plays an important role in pathophysiology of both MSA-P and PD,and abnormal VMHC values in putamen of MSA-P may be helpful in differentiating MSA-P from PD.

Background and Purpose:It has been proved that CD117 may be used as an immunology marker for diagnosis of leukemia of myeloid origin.The relationship between CD117 expression and effect of chemotherapy on the patients with Acute Nonlymphoblastic Leukemia(ANLL) remains unclear.This study is to investigate the relationship between CD117 expression and the response of patients with ANLL to chemotherapy.Methods:Flow cytometery(FCM) was used to detect the positive rate and the levels of CD117 expression of the bone marrow mononuclear cell(BMMNC) from 38 patients with acute lymphoblastic leukemia(ALL) and 81 patients with ANLL,respectively.All-trans Retinoic Acid(ATRA) was taken to treat M_(3) type of ANLL and protocol DA and/or HA was used to treat the other types.ANLL was divided into two groups: positive(+) and negative(-) expression of CD117.At the same time we compared the difference of rates of complete remission(CR) between CD117(+) and CD117(-) groups from ANLL after chemotherapy.Results:Positive percentage of expression of CD117 in ALL and ANLL groups were 13% and 70% respectively(P=0.000).Positive levels of CD117 decreased successively as follows: M_(3)/ M_(1)、M_(2)/ M_(6) / M_(4)、M_(5).CR rates of CD117(+) and CD117(-) groups of ANLL after chemotherapy were 51%(29/57) and 67%(16/24)(P=0.192),respectively.Conclusions:CD117 may serve as an immunology marker for the diagnosis of ANLL,but positive or negative expression of CD117 in ANLL was not associated with the response of the patients with ANLL to chemotherapy.

Objective:To study expressions of CD117 and CD34 in the patients with acute promyelocytic leukemia(APL,M3) and in M1-M2 subtype from FAB classification for acute leukemia(AL).The focus of the study would be laid on the clinical significance of CD117/CD34 co-expression in the patients of M3 subtype.Methods:Researched cases of acute nonlymphoblastic leukemia(ANLL) were divided into two groups:M1-M2 subtype and M3 subtype.Flow cytometery(FCM) was used to detect the rates of positive expression of CD117 and CD34 on bone marrow mononuclear cell(BMMNC) in 54 patients of M3 and 63 patients of M1-M2 subtype respectively.Meanwhile,we compared the differences between the rates of expression of CD117 and CD 34.And,the rates of CD117/CD34 co-expression in patients of M1-M2 subtype and M3 subtype were studied.Results:Our results revealed that the positive rates of CD117 expression in M1-M2 subtype and M3 subtype were 71.4%(45/63) and 66.7%(36/54) respectively(P=0.58).The positive rates of CD34 expression in M1-M2 subtype and M3 subtype were 66.7%(42/63) and 11.1%(6/54) respectively(P=0.000).The positive rates of CD117/CD34 co-expression in M1-M2 subtype and M3 subtype were 71.1%(45/63) and 7.4%(4/54) respectively(P=0.000).Conclusion:CD117 may be used as immunology marker for leukemia of myeloid origin.CD34 had lower expression in M3 subtype than in M1-M2 subtype.The positive rate of CD117/CD34 co-expression in M3 subtype was significantly lower than that in M1-M2 subtype,which can help for diagnosis of M3 subtype and help differentiate M3 subtype from M1-M2 subtype as well.

0.05). Regarding to the grade of irradiation mucositis, the majority of patients in the treatment group were at stage Ⅰ-Ⅱ,while those in the control at stage Ⅲ-Ⅳ(P0.05).No adverse drug reaction was observed in both groups during irradiation process.Conclusion:Actovegin can postpone the development of irradiation oropharyngeal mucositis and decrease the incidence of gradeⅢ and Ⅳmucositis.

Codon usage bias is an important characteristic of genetic information transfer in organisms. Analysis of codon usage bias of different species is important for understanding the rules on genetic information transfer. The previous method for analysis of codon usage bias is mainly based on genomic data. However, this method is greatly limited, because the genome sequences of higher organisms are still not available up to now. In this study, we found that we could obtain the same optimal codons of Ganoderma lucidum (Curtis: Fr.) P. Karst based on its whole genomic data or large-scale transcriptomic data from its liquid-cultured hyphae, primordium and fruiting body, separately. This result indicated the feasibility to understand the codon usage bias based on the large-scale transcriptomic data. By calculating the proportion of rare codons of Escherichia coli and Saccharomyces cerevisiae in 26 terpene synthases (TS) of G. lucidum, we found that the rare codons of S. cerevisiae have a higher proportion in TS genes, while the rare codons of E. coli have relatively lower, suggesting that the TS genes of G. lucidum are possibly more difficult to be expressed in S. cerevisiae than in E. coli. Chemical synthesis of TS genes according to the yeast optimal codons will be an effective way to solve the problem on the mismatch of gene codon bias between the foreign genes and the host strain.
