Objective To explore the effect of community comprehensive rehabilitation on quality of life in patients with stroke sequelae under the family medical service mode. Methods From October, 2013 to October, 2014, 51 patients with stroke sequelae received compre-hensive rehabilitation intervention for three months, including rehabilitation training, rehabilitation guidance, health education and psycho-logical counseling. They were assessed with modified Barthel index (MBI), WHO-Disability Assessment Schedule (WHO-DASⅡ), Short Form 36 Health Survey Questionnaire (SF-36), Brain Injury Community Rehabilitation Outcome Scales (BICRO-39), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) before and after intervention. Results The scores of physical functionning, role physical, general health, mental health, social functioning and the total score in SF-36 increased after intervention (t>2.072, P<0.05). The scores of so-cial contact, locomotivity, self handling transaction ability and the total score in BICRO-39 decreased after intervention (t>2.434, P<0.05), as well as the scores of getting along with people, housework and society and participation in WHO-DAS II (t>2.507, P<0.05). Conclusion In the community health service, comprehensive rehabilitation guided by multidisciplinary rehabilitation team can facilitate to improve the quality of life in patients with stroke sequela.

Objective:To analyze the biomechanical stress distribution on the sagittal fractured of the mandibular condyle(SFMC) fixed by double plates in 3 different ways.Methods:The fixation finite element models with double straight plates(SS),one straight and one L-form plates(SL),and double L-form plates(LL)were established.The biomechanical stresses on condyle were calculated with finite element analysis.Results:In the model of SS fixation the maximum equivalent stress (MES),maximum total displacement (MTD)and maximum total corner(MTC)of condylar stump were 525.475 MPa,0.902 2 mm and 0.260 1°;MES,MTD,and MTC on fractured free-end were 4.425 MPa,0.882 7 mm and 0.019 9°,respectively.In the model of SL fixation MES,MTD and MTC on condylar stump were 1 135 MPa,0.9367 mm and 0.126 1°;MES,MTD and MTC on fractured free-end were 2.656 MPa,0.887 1 mm and 0.016 9°,respectively.In the model of LL fixation MES,MTD and MTC on condylar stump were 2 208 MPa,0.923 8 mm and 0.172 2°;MES,MTD and MTC on fractured free-end were 14.66 8 MPa,0.876 6 mm and 0.018 1°,respectively.Conclusion:Double L plates fixation is a proper way for SFMC.

Objective_To investigate whether hUCMSCs undergo malignant transformation when exposed to MCF-7B breast cancer microenvironment and whether the abnormal activation and over expression of STAT3 play an impor-tant role in this transformation.Methods_The experiment was divided into three groups:blank group ( hUCMSCs were separately cultured),experimental group(hUCMSCs were indirectly co-cultured with MCF-7B breast cancer cells),positive control group(MCF-7B breast cancer cells were separately cultured).Morphology of cells was detec-ted by invertedmicroscope.Cell cycle was detected by flow cytometry.The mRNA expression of STAT3, c-Myc and Bcl-xL was tested by real-time PCR.The protein expression and location of p-STAT3,c-Myc and Bcl-xL were detected by immunofluorescence.The protein expressions of p-STAT3,STAT3,c-Myc and Bcl-xL were also meas-ured by Western blot.Results_The experimental group cells showed typical morphology of the tumor cells.The cells proportion of experiment group in G1 phase was significantly lower than that of the blank group(P<0.05),but which in S and G2 phase were significantly higher than those of the blank group(P<0.05).The mRNA expression levels of STAT3 ,c-Myc and Bcl-xL in experimental group was significantly higher than those in blank group ( P<0.05).p-STAT3,STAT3,c-Myc and Bcl-xL protein were significantly higher than those of the blank group(P<0.05),and they were mainly located in the nuclei.The protein expression of STATS also showed significant changes in experimental group.Conclusions_hUCMSCs trends to malignant transformations when exposed to MCF-7B breast cancer microenvironment.The abnormal activation and over expression of STAT3 are of important factors leading to the malignant transformation of hUCMSCs.

The secondary metabolites of plants are important sources of natural drugs. Betula plants have abundant pharmacological value, complex mechanism and wide applications, which are closely related to the triterpenoids of theirs. Triterpenoids in Betula species are mainly divided into dammarane-type, ocotillol-type, oleanane-type, lupane-type and cycloaltunane-type. The extracts of Betula species have varieties of activities such as anti-tumor, anti-inflammatory, anti-oxidant, anti-bacterial, etc. And the biosynthetic pathways of triterpenoids after 2,3-oxidosqualene are split into four branches of dammarenediol-II, lupeol, cycloartenol and amyrin according to the different oxidosqualene cyclases. This review summarizes the chemical constituents, pharmacological activities and biosynthetic pathways of triterpenoids in Betula plants. It provides a reference for the research and development of new drugs and the production of these triterpenoids in microbial cell factories by synthetic biology methods.

The aim of this thesis is to prepare etoposide submicro-emulsion (ESE) for intravenous injection and investigate its characteristics in vitro and in vivo. High-pressure homogenization was used to prepare ESE, using 10% (w/w) soybean oil and 10% (w/w) medium-chain triglyceride as mixed oil phase, and 1.8% (w/w) fabaceous lecithin as emulsifier. The pH was adjusted to 5.5 with 0.1 mol x L(-1) NaOH to keep the most stability of ESE. The particle size distribution and zeta potential were measured using photon correlation spectroscopy. Ultrafiltration was used to estimate the relative percentages of etoposide in each phase. Long-term storage test and accelerated isothermal test-Weibull distribution method were used to estimate the physical and chemical stability of ESE. Plasma pharmacokinetics in rats was monitored by high performance liquid chromatography by comparison with etoposide nonaqueous solution at the same time. The mean particle size, zeta potential and entrapment efficiency of ESE were (189.9 +/- 54.6) nm, - 32.6 mV and 91.7%, respectively. The emulsion was stable during 9 month storage at 4 degrees C. The shelf life (T0.9) of etoposide in lipid emulsion was estimated to be about 665 days at 4 degrees C. The drug concentration-time curves of ESE and solution were similar and could be described by two compartment model. The area under the curve of concentration versus time from zero to the last time point and the mean residence time of ESE and solution were (18.30 +/- 8.74) and (19.32 +/- 6.45) microg x h x mL(-1), and (1.46 +/- 0.32) and (1.71 +/- 0.52) h, respectively. Etoposide was incorporated in submicro-emulsion to improve its physical and chemical stability without addition of organic solvents with insignificant different characteristics in vivo when compared with solution.

Objective To analyze the influential factors of healthy children′s heart rate turbulence (HRT). Methods One hundred and six healthy children with ventricular premature beat (VPB) were selected in this study and the correlation among HTR parameters as turbulence onset (TO) and turbulence lope (TS) and age, gender, basic heart rate, the number of VPBs were analyzed. Results It was observed that among three age groups, TO decreased with the age, and the difference was statistically significant (P < 0.05), but there was no significant gender difference (all P > 0.05). TS increased with the age, and intergroup difference was statistically significant (P < 0.05). In the group of children aged over seven, significantly higher TS was observed among boys (P < 0.05), while in the group of children aged 1 to 3 and the group aged 3 to 7 , there was no significant gender difference (P > 0.05). TO and TS decreased with the decline of heart rate (r = 0.494, P < 0.00; r = -0.569,P < 0.00 respectively), and the correlation between TO and HR, TS and HR was found.The number of VPBs had no significant correlation with TO or TS (r = 0.104,P = 0.290; r = 0.122,P =0.212). Conclusions The results demonstrate that influenced by age and basic heart rate, healthy children′s HRT increases with the age and the decline of heart rate. Therefore, the reference index of children′s HRT should differ from that of adults, which requires further evaluation.

Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.
