Russia's post-degree medical education first appeared in the end of the 19th century and had improved along with the progress in science, technology and education. From 1990s, new waves of technology revolution and the rise of post-occupation training further pushed the post-degree medical education to move forward. Legally established post-degree education as a form of occupational education enables Russian medical professionals to constantly update knowledge and absorb new information to keep up with the new developments in medical science and technology. In this sense, post-degree medical education has become a major way to train not only medical professionals but professionals of acupuncture and moxibustion, and thus has been of great significance for TCM and acupuncture to transmit and develop in Soviet Union and Russia. This paper introduced the general situation of post-degree medical education in Russia, its influence to the transmission and development of TCM and acupuncture in Soviet Union and Russia, as well as the enlightenment to medical education.

OBJECTIVE:
To observe the expression and anti-apoptosis of microRNA-21(miR-21) in rat myocardium during early ischemia-reperfusion injury (I/R).
METHODS:
Sprague-Dawley rats were randomly divided into 5 groups: a control group (transfected with rAAV9-ZsGreen by coronary injection), a miR-21group (transfected rAAV9-ZsGreen-premiR- 21 by coronary injection), a sham group (open-chest only), an I/R group (I/R), and an I/ R+miR-21 (I/R after transfected rAAV9-ZsGreen-pre-miR-21 by coronary injection). Realtime PCR was used to assess the expression level of miR-21. Immunohistochemistry and Western blot were used to determine the expression of Bcl-2, Bax, caspase-3 and Bcl-2/Bax.
RESULTS:
MiR-21 was increased by 4.43 times in the miR-21 group (P<0.001). MiR-21 was downregulated in the ischemia zone after I/R compared with the sham group (P<0.05), but that in the non-ischemia zone was significantly increased compared with the sham group (P<0.01). MiR- 21 expression was decreased in the I/R group compared with that in the sham group at 1 h, 2 h and 6 h after I/R (P<0.05), and it was up-regulated in the I/R+miR-21 group at the same time point compared with the I/R group (P<0.01). The expression of Bcl-2, Bax, and caspase-3 was upregulated and Bcl-2/Bax was decreased in the ischemia zone in the I/R group and I/R+miR-21 group than the sham group(P<0.05). Compared with the I/R group, the expression of Bcl-2 and caspase-3 was down-regulated and Bcl-2/Bax was increased in the ischemia zone in the I/ R+miR-21 group (P<0.05).
CONCLUSION
MiR-21 expression is down-regulated and cell apoptosis is increased in rat myocardium during early ischemia-reperfusion injury. Myocardial cell apoptosis may be alleviated by miR-21 over-expression.

Objective To investigate the clinical effect of induction chemotherapy plus concurrent radiochemotherapy in the treatment of locally advanced non-small cell lung cancer (NSCLC) through a meta-analysis.Methods CBM, CNKI, Cochrane Library, PubMed, and EMbase were searched for the articles on comparison between induction chemotherapy plus concurrent radiochemotherapy and concurrent radiochemotherapy for patients with locally advanced NSCLC.According to the inclusion and exclusion criteria, the data on short-term outcome and survival were collected.A Meta-analysis was performed to evaluate the clinical effect of induction chemotherapy followed by concurrent radiochemotherapy.Results A total of 5 articles were included, which involved 845 patients.The results showed that the short-term outcome and the 2-and 3-year survival rates were similar between patients receiving induction chemotherapy plus concurrent radiochemotherapy and those receiving concurrent radiochemotherapy ( OR=0.875, 95% CI 0.507-1.510, P=0.631;HR=0.770, 95% CI 0.515-1.151, P=0.203;HR=0.809, 95% CI 0.559-1.172, P=0.262), but the patients receiving induction chemotherapy plus concurrent radiochemotherapy showed a significantly higher incidence rate of grade ≥ 3 leukopenia than those receiving concurrent radiochemotherapy alone ( OR=0.637, 95% CI 0.435-0.931, P=0.020).Conclusions Induction chemotherapy plus concurrent radiochemotherapy shows no significant advantages over concurrent radiochemotherapy alone in the short-term outcome and 2-and 3-year survival rates, but it significantly increases myelosuppression.Since there are few studies involving a limited number of cases included in this analysis, more multicenter randomized trials are needed to provide more detailed data and further clarify the clinical value of induction chemotherapy plus concurrent radiochemotherapy.

Objective To examine the effects of different pre-treatment nutritional status and inflammatory markers on acute adverse reactions in esophageal cancer patients during concurrent intensity-modulated radiation therapy (IMRT) and chemotherapy.Methods The acute adverse reactions of 338 eligible esophageal cancer patients who received concurrent IMRT and chemotherapy in our hospital from 2006 to 2014 were reviewed.The effects of different pre-treatment nutritional status, such as body mass index level (BMI), albumin level (ALB), total lymphocyte count (TLC), the presence or absence of anemia, and inflammatory indicators including neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR), on acute adverse reactions in the patients were examined.Data were analyzed using the chi-square test with continuity correction and logistic regression analysis.Results The incidence rate of malnutrition in the patients based on their nutritional status was 5.62%-54.14%.The incidence rate of grade≥2 acute radiation esophagitis (RE) was significantly higher in the low ALB group than in the normal ALB group (P=0.000).The incidence rate of adverse reactions in the hematologic system increased as TLC decreased (P=0.006), but the incidence rate of acute radiation pneumonitis (RP) was reduced as TLC decreased (P=0.001).In addition, the incidence rate of grade ≥2 acute RE was significantly higher in the anemia group than in the non-anemia group.Inflammatory marker analysis demonstrated that the incidence rate of acute RE was significantly higher in the high NLR group and high PLR group than in the low NLR group and low PLR group (P=0.000 and P=0.024, respectively).Logistic regression analysis of nutritional status and inflammatory markers showed that TLC was an independent risk factor for acute adverse reactions in the hematologic system (P=0.001), and ALB and PLR were independent risk factors for acute RE (P=0.017 and P=0.011,respectively).Conclusions Nutritional status and inflammatory markers are associated with concurrent chemoradiotherapy-induced acute adverse reactions in esophageal carcinoma patients, and hence may be valuable indicators of acute adverse reactions during treatment.In addition, nutritional treatment and support care should be actively provided to the patients to prevent the development of acute adverse reactions during treatment.

OBJECTIVE:
To investigate the expression of periostin in in vitro cultured vascular smooth muscle cells (VSMCs) induced by TGF-β1 and the relationship between periostin expression and the migration and proliferation of the VSMCs. Further, to investigate the effects of atorvastatin on the above-mentioned processes and the molecular mechanisms of atorvastatin inhibition of TGF-β1- induced periostin production.
METHODS:
Rat aorta smooth muscle cells were cultivated by the method of tissue explants adherence. Cells of generation 3 to 6 were used as the experimental system. Primary cultured rat vascular smooth muscle cells were treated by TGF-β1 and different concentrations of atorvastatin,Y-2763 (Rho kinase inhibitor), or atorvastatin plus MVA for 24 hours. The expression of periostin was measured by RT-PCR and Western blot. A Boyden chamber assay was used to measure cell migration, and an MTT test was used to measure cell proliferation.
RESULTS:
Periostin expression in rat VSMCs stimulated by TGF-β1 increased significantly (4.158 ± 0.515 vs 0.385 ± 0.031), VSMC migration(25 ± 4 vs 8 ± 2) and proliferation (0.85 ± 0.06 vs 0.32 ± 0.03) also increased significantly. Atorvastatin significantly inhibited TGF-β1-induced periostin production in rat VSMCs, as well as VSMC migration and proliferation, in a dose-dependent manner. Rho kinase inhibitor Y-27632 significantly inhibited TGF-β1-induced periostin production in rat VSMCs (2.082 ± 0.245). The inhibitory effect of atorvastatin on periostin upregulation induced by TGF-β1 was reversed by mevalonate (3.838 ± 0.326).
CONCLUSION
Periostin can promote rat VSMC migration and proliferation. Atorvastatin inhibition of periostin expression induced by TGF-β1 in VSMCs may be exerted by inhibition of the production of MVA and other isoprene compounds and by blocking the Rho/Rho kinase signaling pathway.
