OBJECTIVE: To study the preventive effect of Breviscapus Injection on the chronic hypoxic myocardium injury in rats and its mechanism. METHODS: Transmission electron microscope and biochemical analysis were used to assay the therapeutic effect of Breviscapus Injection in rat model induced by 4 week's hypoxia. RESULTS: The contents of malondialdehyde (MDA) and Ca(2+) in the homogenate of myocardial tissue of the hypoxic rats were significantly higher than those of the control rats. The activities of superoxide dismutase (SOD), nitric oxide synthase (NOS) in the homogenate of myocardial tissue and the plasmic NO levels of the hypoxic rats were significantly lower than those of the control rats. Breviscapus Injection reduced the contents of MDA and Ca(2+), and increased the levels of SOD, NOS and NO. Ultrastructural examination revealed that the injuries of the ultrastructure of heart in hypoxic rats were improved by treatment with Breviscapus Injection. CONCLUSION: Breviscapus Injection can effectively prevent and treat the hypoxia-induced myocardial damage. One of its mechanisms may relate to its adjusting NO level, anti-damaging of free radicals and inhibiting calcium overload.

Conclusion 99mTc2ECD SPECT imaging had been proved to be an objective parameter for evaluating the therapeutic effect of the various treatments of AMI. Thrombolysis plus delayed stenting was more effective than thrombolysis.

Objective: To investigate the quality of life and its influencing factors among patients with gestational diabetes mellitus (GDM), so as to provide insights into the improvements in the quality of life among patients with GDM. Methods: GDM patients admitted to Department of Obstetrics and Gynecology, Hangzhou First People's Hospital Affiliated to Zhejiang University Medical School from June 2021 to June 2022 were recruited. Participants' demographics, diagnosis and treatment, sleep quality, depression and social support level were collected. Patients' quality of life was evaluated using the Quality of Life Scale for Pregnant Women with Gestational Diabetes Mellitus, and the factors affecting the quality of life were identified among patients with GDM using a multivariable linear regression model. Results: A total of 300 questionnaires were allocated, and 284 valid questionnaires were recovered, with an effective recovery rate of 94.67%. The respondents had a mean age of (32.81±4.93) years, and the mean scores for the quality of life was (92.63±14.10) points. Multivariable linear regression analysis identified depression (β'=-0.293), sleep disorder (β'=-0.177), insulin therapy (β'=-0.316), regular exercise (β'=0.272) and social support level (medium: β'=0.153; high: β'=0.381) as factor affecting the quality of life among GDM patients. Conclusions GDM patients have a low quality of life. Depression, sleep disorders, insulin therapy, and lack of exercises may cause a decline in the quality of life among GDM patients, and strong social support facilitates the improvements in the quality of life among GDM patients.

Objective To establish a TaqMan probe-based real-time fluorescent quantitative PCR ( real-time PCR) for the quantitative and rapid detection of viral reservoir in peripheral blood mononuclear cells (PBMCs) isolated from rhesus monkeys with simian immunodeficiency virus (SIV) infection and to evaluate its preliminary application. Methods A pair of primers and one TaqMan probe were designed ac-cording to the conserved sequence of SIVmac239 strain for real-time PCR amplification. A length of 2 090 bp of nucleotide fragment was digested from the plasmid p239SpSp5 containing 5′-end long segments of SIV-mac239 strain by restriction enzymes EcoRⅠand SpeⅠ. The standards used for quantitative detection of SIV DNA in peripheral blood samples were prepared by a 10-fold serial dilution and used for graphing the stand-ard curve. The numbers of SIV DNA ( copies per 106 PBMCs) in rhesus monkeys during acute and chronic phases of SIVmac239 infection were determined and the virological characteristics of SIV DNA at different phages of infection were analyzed. Results A linear positive correlation between cycle threshold ( Ct) val-ues and concentrations (10 copies/μl to 109 copies/μl) of the standards was found. High levels of SIV DNA were monitored in SIV-infected monkeys 14 to 22 days after acute infection. The levels of SIV DNA in the acute phase of infection were about 1 to 2 logs higher than those in the chronic phase of infection. The num-bers of SIV DNA ( copies per 106 PBMCs) were 1 log lower than the SIV viral load in peripheral blood of the same monkey. The ratios of SIV DNA load to SIV RNA load ( DNA/RNA) in chronic phase of infection were higher than those in the acute phase. Conclusion The established TaqMan probe-based real-time fluorescent quantitative PCR was a highly sensitive and specific assay for the detection of SIV DNA with an advantage of wide linear range. It could be used for the quantitative evaluation of latent reservoirs of SIV.
