A triple-transgenic (tyrosine hydroxylase/dopamine decarboxylase/GTP cyclohydrolase 1, TH/DDC/GCH1) bone marrow mesenchymal stem cell line (BMSCs) capable of stably synthesizing dopamine (DA) transmitters were established to provide experimental evidence for the clinical treatment of Parkinson's disease (PD) by using this cell line. The DA-BMSCs cell line that could stably synthesize and secrete DA transmitters was established by using the triple transgenic recombinant lentivirus. The triple transgenes (TH/DDC/GCH1) expression in DA-BMSCs was detected using reverse transcription-polymerase chain reaction (RT-PCR), Western blotting, and immunofluorescence. Moreover, the secretion of DA was tested by enzyme-linked immunosorbent assay (ELISA) and high-performance liquid chromatography (HPLC). Chromosome G-banding analysis was used to detect the genetic stability of DA-BMSCs. Subsequently, the DA-BMSCs were stereotactically transplanted into the right medial forebrain bundle (MFB) of Parkinson's rat models to detect their survival and differentiation in the intracerebral microenvironment of PD rats. Apomorphine (APO)-induced rotation test was used to detect the improvement of motor dysfunction in PD rat models with cell transplantation. The TH, DDC and GCH1 were expressed stably and efficiently in the DA-BMSCs cell line, but not expressed in the normal rat BMSCs. The concentration of DA in the cell culture supernatant of the triple transgenic group (DA-BMSCs) and the LV-TH group was extremely significantly higher than that of the standard BMSCs control group (P < 0.000 1). After passage, DA-BMSCs stably produced DA. Karyotype G-banding analysis showed that the vast majority of DA-BMSCs maintained normal diploid karyotypes (94.5%). Moreover, after 4 weeks of transplantation into the brain of PD rats, DA-BMSCs significantly improved the movement disorder of PD rat models, survived in a large amount in the brain microenvironment, differentiated into TH-positive and GFAP-positive cells, and upregulated the DA level in the injured area of the brain. The triple-transgenic DA-BMSCs cell line that stably produced DA, survived in large numbers, and differentiated in the rat brain was successfully established, laying a foundation for the treatment of PD using engineered culture and transplantation of DA-BMSCs.

Objective:To explore the distribution characteristics of brachial-ankle pulse wave velocity (BaPWV) in adolescents.Methods:Cross sectional survey research.A total of 1 607 adolescents aged 12-17 years from 5 middle schools in the Haidian District, Beijing from June 2020 to May 2021 were enrolled for measuring their blood pressure, weight, height and the body mass index (BMI), including 782 males and 825 females.BaPWV was measured using an arteriosclerosis detector.They were divided by the age, sex and obesity.Differences of measurement data among multiple groups were compared by one-way ANOVA, followed by the LSD test, and those between groups were compared by the two-sample t-test.The correlation between BaPWV and other indexes was assessed by the Pearson correlation analysis. Results:The median level of BaPWV in adolescents aged 12-17 years increased with age, which was 982.50 cm/s in adolescents aged 12 years, and maximum 1 113.50 cm/s those aged 17 years.BaPWV in adolescents aged 12-17 years was positively correlated with age ( r=0.936, P=0.006). Subgrouped by the sex, the median BaPWV of male and female adolescents aged 12 years was 962.25 cm/s and 997.50 cm/s, respectively, which reached 1 122.50 cm/s and 1 096.00 cm/s in those aged 17 years, respectively.BaPWV of male and female adolescents was positively correlated with the age ( r=0.903, P=0.014; r=0.945, P=0.004). In male adolescents, BaPWV was positively correlated the systolic and diastolic blood pressure, age, weight, height, BMI( r=0.308, P<0.001; r=0.289, P<0.001; r=0.478, P<0.001; r=0.190, P<0.001; r=0.315, P<0.001; r=0.109, P=0.002). In female adolescents, BaPWV also was positively correlated the systolic and diastolic blood pressure, age, weight, height, BMI( r=0.340, P<0.001; r=0.285, P<0.001; r=0.379, P<0.001; r=0.115, P=0.001; r=0.170, P=0.001; r=0.097, P=0.014). In the overall population, BaPWV was statistically significant between the obese and normal groups ( t=-3.428, P=0.001). No significant difference in BaPWV between male and female adolescents aged 12-13 years was identified ( t=0.123, P=0.902 ), but it was significantly lower in female adolescents aged 14-15 years and 16-17 years than those of age-matched males( t=2.315, P=0.021; t=2.152, P=0.032). Conclusions:The median BaPWV level in adolescents aged 12-17 years, increases with the age.Systolic blood pressure, diastolic blood pressure, body weight, BMI, age and height are positively correlated with BaPWV in adolescents.Obesity can increase the stiffness of blood vessels, which is influenced by the sex.

OBJECTIVE: To investigate the effect of calmodulin (CaM) and its mutants on binding to voltage-gated Na channel isoleucine-glutamine domain (Na1.2 IQ). METHODS: The cDNA of Na1.2 IQ was constructed by PCR technique, CaM mutants CaM, CaM and CaM were constructed with Quickchange site-directed mutagenesis kit (QIAGEN). The binding of Na1.2 IQ to CaM and CaM mutants under calcium and calcium free conditions were detected by pull-down assay. RESULTS: Na1.2 IQ and CaM were bound to each other at different calcium concentrations, while GST alone did not bind to CaM. The binding affinity of CaM and Na1.2 IQ at [Ca]-free was greater than that at 100 nmol/L [Ca] ( < 0.05). In the absence of calcium, the binding amount of CaM wild-type to Na1.2 IQ was greater than that of its mutant, and the binding affinity of CaM to Na1.2 IQ was the weakest among the three mutants ( < 0.05). CONCLUSIONS The binding ability of CaM and CaM mutants to Na1.2 IQ is Ca-dependent. This study has revealed a new mechanism of Na1.2 regulated by CaM, which would be useful for the study of ion channel related diseases.

Objective To establish the regression equation of blood pressure in population based on the pulse wave transit time (PWTT) and verify its accuracy. Methods A convenient sampling method was used to collect gender, age, arm circumference, arm length, PWTT, history of hypertension, and body height, etc. of 4 121 outpatients' information from the Hainan Branch of Chinese PLA General Hospital from June 2016 to May 2018 to establish a binary variable logistic regression equation for blood pressure elevation or not and screen out the influencing factors of time point blood pressure. The accuracy of the equation was then verified in 252 outpatients. Results Logistic regression analysis showed that PWTT, gender, age, history of hypertension present or not, body height might be the influencing factors of blood pressure elevation [odds ratio (OR) values were 0.995, 0.530, 0.980, 107.128, 0.979, 95% confidence interval (95% CI) were 0.991-0.999, 0.405-0.695, 0.971-0.989, 73.935-155.223, and 0.962-0.996, respectively, all P < 0.05]. The classification prediction equation: Ln [P / (1-P)] = 2.087-0.005×PWTT-0.635×gender (man = 1, woman = 2)-0.02×age + 4.674×hypertension history present or not-0.021×body height [P indicates the probability of a positive result: systolic blood pressure≥140 mmHg (1 mmHg = 0.133 kPa) and/or diastolic blood pressure≥90 mmHg]. The overall test results showed that χ2 = 1 835.305, P < 0.05, statistically significant; The goodness of fit test results:χ2 = 5.881, P > 0.05, the data was conform to the equal proportion distribution. Model-confirmed results showed that in patients with a history of hypertension, the probability of predicting accuracy was 95%-99%. In patients without a history of hypertension, the probability of predicting accuracy was 45%-89%. Conclusion The predictive value of blood pressure elevation with this model in patients with a history of hypertension is superior to that of patients without the history of hypertension.

Objective: To evaluate the effects of the intervention based on WeChat on blood pressure control in patients with essential hypertension. Methods: The databases of CNKI，Wanfang，VIP，PubMed and the Cochrane Library were researched for the literatures about effects of the intervention based on WeChat on blood pressure control in patients with essential hypertension published from 2011 to 2018. These papers were retrieved and evaluated according to inclusion and exclusion criteria. Stata 12.0 software was used for meta analysis. Results: Eleven out of 880 papers were included into meta analysis. There were 1 174 cases，with 587 cases in the experimental group and 587 cases in the control group. The results of the meta analysis showed that compared with traditional health intervention method，the intervention based on WeChat significantly reduced the level of systolic blood pressure（WMD=14.77，95%CI：11.76-17.77）and diastolic blood pressure（WMD=8.17，95%CI：5.67-10.67）of hypertensive patients. Subgroup analysis showed that the longer the intervention，the better the effects（P<0.05）. Conclusion The intervention based on WeChat is more helpful than traditional health intervention for blood pressure control of patients with essential hypertension.

This study was designed to investigate the correlation between autophagy and polarization of macrophages in atherosclerosis (AS) plaque in arteriosclerosis obliterans amputees. Femoral artery specimens from arteriosclerosis obliterans amputees were performed hematoxylin and eosin (HE) staining, oil red O and immunofluorescence staining to observe the morphology of atherosclerotic plaque, phenotype of macrophages and autophagy in plaque; using real-time quantitative RT-PCR technology to detect the mRNA level of M1 and M2 type markers in arterial tissue; to analyze polarized signal pathway and autophagy protein levels in macrophages by Western blotting. Arterial specimens staining showed obvious lipid deposition and obvious infiltration of amount of foam cells and inflammatory cells. Macrophages were mainly expression M1 type in percentage in fibrous plaque. Although both M1 and M2 macrophages were upregulated in atheromatous plaque, the increase was dominant in M2 type in percentage. The level of autophagy was significantly higher in the atheromatous plaque than that of fibrous plaque. The expression of tumor necrosis factor- α (TNF-α), monocyte chemotactic protein-1 (MCP-1), inducible nitric oxide synthase (iNOS), interleukin-6 (IL-6) and interleukin-12 (IL-12) mRNA was significantly higher in fibrous plaque than that of atheromatous plaque (P < 0.01 or 0.05), and arginase-1 (Arg-1), transforming growth factor-β (TGF-β), CD163 and interleukin-10 (IL-10) mRNA was significantly lower than that in atheromatous plaque (P < 0.01). The levels of p-STAT1 and NF-κB were significantly increased in fibrous plaque (P < 0.01), while p-STAT6 expression was significantly increased in atheromatous plaque (P < 0.01). The level of LC3-II was significantly higher in atheromatous plaque than that in fibrous plaque (P < 0.01). Macrophages in early atherosclerotic plaque were induced to M1 type through p-STAT1/NF-κB pathway and expressed moderate levels of autophagy; while macrophages in advanced plaques were induced to polarization of M2 type through p-STAT6 pathway. M2 macrophages expressed a higher level of autophagy than M1 macrophages.
