Objective To investigate the effects of human umbilical cord mesenchymal stem cells (hUCMSCs)transplantation on the treatment of hypoxic-ischemic encephalopathy(HIE). Methods A total of 25 HIE patients were randomly divided into stem cell transplantation group(15 case)and control group(10 cases). The patients in transplantation group were given intravenous infusion of hUCMSCs,which isolated under sterile condition in vitro and cultured, while in control group were treated with routine drug treatment. Neurological function( American National Institutes of Health Stroke Scale( NIHSS ),Barthel index (BI)),extrapyramidal function(Unified Parkinson's disease questionnaire(UPDRS)),cognition and emotional reaction(The mini mental state examination(MMSE),the 14 item Hamilton Depression Scale(HAMD14)and HAMD24)were all assessed before and after transplantation for 14 d,90 d and 180 d respectively to evaluate the clinical efficacy of hUCMSCs transplantation. Results There was no significant difference between two groups in terms of each function before transplantation. The scores of transplantation group were all obviously improved after treatment for 14 d,90 d and 180 d compared to that of before treatment,and the therapy effect in transplantation group was significantly better than that of the control group( NIHSS:Ftime =4. 372,P=0. 031;Ftime*group =4. 175,P=0. 038;Fgroup =3. 897,P=0. 045.BI:Ftime =4. 728,P=0. 044;Ftime*group =4. 894,P=0. 037;Fgroup =4. 284,P=0. 039.UPDRS:Ftime =5. 112,P=0. 047;Ftime*group =4. 895,P=0. 045;Fgroup=3. 879,P =0. 031.MMSE:Ftime =5. 135,P =0. 039;Ftime*group =3. 213,P =0. 036;Fgroup =4. 184,P=0. 045.HAMD14:Ftime =3. 977,P =0. 049;Ftime*group =4. 587,P =0. 038;Fgroup =4. 381,P =0. 041.HAMD24:Ftime =3. 845,P =0. 033;Ftime*group =4. 125,P=0. 035;Fgroup =3. 547,P=0. 034). Conclusion Transplantation of hUCMSCs is safe and effective for treatment of HIE,which can significantly improve the neurological function,extrapyramidal function,cognition and emotion.

BACKGROUND:Currently, neural stem celltransplantation can be performed through three main approaches:local lesions, blood circulation, and cerebrospinal fluid.
OBJECTIVE:To review the transplantation of neural stem cells or neural precursor cells via the cerebrospinal fluid in the treatment of central nervous system diseases.
METHODS:A computer-based search of PubMed and CHKD databases was performed to retrieve articles concerning transplantation of neural stem cells via the cerebrospinal fluid, and its application and therapeutic mechanism in the treatment of central nervous system diseases in both animal experiment and clinic study published from 2000 to 2009.
RESULTS AND CONCLUSION:It is suitable for neural stem cellsurvival, proliferation, and differentiation in the cerebrospinal fluid. Transplantation of neural stem cells via the cerebrospinal fluid is effective and feasible to treat central nervous system diseases. However, some problems have not been solved, such as the source of neural stem cells, the optimal time window and celldose, the safety and the long-term effect. Further studies are needed to pave the way for the intrathecal injection of neural stem cells in the treatment of central nervous system diseases.

Objective:To preliminarily study the effect of Louqin Zhisou decoctions with the mechanism of clearing heat and resol-ving phlegm on the blood level of neutrophil elastase ( NE) in the rat model of acute exacerbation of chronic obstructive pulmonary dis-ease ( AECOPD) . Methods:The rat model of AECOPD was established by passive cigarette smoking, intratracheal instillation of li-popolysacchricle ( LPY) and intranasal instillation of staphylococcus aureus. Totally 60 AECOPD rats were randomly divided into 3 groups, the model control group (n=20), ambrohexel group (n=20), and Louqin Zhisou decoctions group (n=20). NE was detec-ted by ELISA. Results:Compared with that before the treatment, NE in ambrohexel group and Louqin Zhisou decoctions group was de-creased significantly(P<0. 01). Conclusion:Clearing heat and resolving phlegm method probably can decrease NE by reducing air-way mucus hypersecretion and obstruction in AECOPD rats.

Objective:To investigate clinical significance of the detection of bone mineral density(BMD)and serum levels of vitamin D in elderly patients with Parkinson's disease(PD).Methods:Sixty elderly patients with PD(the PD group)admitted in our hospital from June 2016 to December 2018 were enrolled in this retrospective study.And 60 healthy persons confirmed by annual health check-up matched for age and sex during the same period were included as the control group.PD patients were divided into the osteoporosis group(n=23)and the non-osteoporosis group(n=37). The clinical data, bone mineral density and serum vitamin D level were compared between the two groups.Multivariate Logistic regression method was used to analyze related factors for osteoporosis in PD patients.Results:The incidences of osteoporosis and vitamin D deficiency were higher in PD group than in control group[23 cases(38.3%) vs.13 cases(21.7%)、35 cases(58.3%) vs.21 cases(35.0%), all P<0.05]. Bone mineral density and serum 25-(OH)D level were lower in PD group than in control group[(0.77±0.08)g/m 2vs.(0.83±0.09)g/m 2, (25.65±8.65)nmol/L vs.(39.80±10.74)nmol/L, t=4.381 and 8.439, P<0.05]. The age, course of disease and H-Y grade were higher and serum level of 25-(OH)D was lower in the osteoporosis group than in the control group( P<0.05). Spearman correlation analysis showed that BMD and 25-(OH)D were negatively correlated with age, course of disease and H-Y stage, respectively, and BMD was positively correlated with 25-(OH)D( r=0.396, P<0.05). Multivariate Logistic regression analysis showed that vitamin D deficiency was an independent risk factor for osteoporosis in elderly PD patients( OR=2.332, 95% CI: 1.772-8.224, P<0.01). Conclusions:The incidence of osteoporosis is high in elderly PD patients, and vitamin D deficiency is often present.Vitamin D deficiency may be an independent risk factor for osteoporosis.
