BACKGROUND:Poststroke depression is one of the most common psychological behavior disorders after stroke and its mechanism remains unclear. Studies have suggested that microRNAs (miRNAs) involved in neurogenesis and synaptogenesis may play an important role in psychology diseases. OBJECTIVE:To observe the expression of miR-137 in the blood and brain of poststroke depression rats and its effect on the behaviors of rats. METHODS:Thirty-six rats were equal y divided into six groups:control, model, agomir-137, agomir-NC, agomir-137+Grin2A and agomir-137+vector groups. Control group had no treatment. Poststroke depression models were established by ligation of middle cerebral artery and chronic mild stimulation in the latter four groups fol owed by receiving an injection of nothing, agomir-137, agomir-NC, LV-CMV-Grin2A or control plasmids into the left lateral ventricle, respectively. RESULTS AND CONCLUSION:We found significantly lower miR-137 levels in the brain and peripheral blood of post-stroke depression rats compared with normal rats. Vertical scores and horizontal scores on the behavior test were significantly higher in the agomir-137 group than the agomir-NC and model groups at 3 weeks after cerebral ischemia;while, sucrose consumption percentage was also higher in the agomir-137 group at the end of 2 weeks after cerebral ischemia. Luciferase assays showed miR-137 bound to the 3’ UTR of Grin2A, regulating Grin2A expression in a neuronal cel line. Grin2A gene overexpression in the brain of post-stroke depression rats noticeably suppressed the inhibitory effect of miR-137 on post-stroke depression. Overal , these findings show that miR-137 suppresses Grin2A protein expression through binding to Grin2A mRNA, thereby exerting an inhibitory effect on post-stroke depression and offering a new therapeutic target for poststroke depression.

OBJECTIVETo observe the therapeutic effect of Qingfei Huatan Quyu method (QHQ, a Chinese medicinal therapy for clearing Fei-heat and dissolving phlegm-stasis) combined with hormone-antibiotic therapy (HAT) on radiation pneumonia (RP).

METHODSEighty-one patients with RP were randomized into two groups, 41 patients in the control group and 40 in the treatment group were treated with HAT alone and HAT combined with QHQ respectively for 21 days. The severity of RP was evaluated before and after treatment according to the criteria of the radiation therapy oncology group. The effect on TCM symptoms and chest roentgenogram, as well as on plasma levels of interleukin-6 ( IL-6) and transform growth factor-beta (TGF-beta) were detected.

RESULTSAfter treatment, number of patients with RP graded as 0, 1, 2, 3, and 4 in the treatment group was 23, 10, 4, 2, and 1, respectively, while in the control group, 14, 9, 11, 4, and 3, respectively. The combined therapy showed effects in improving RP grading (P <0.01) and TCM syndromes were superior to those of HAT respectively (P < 0.05). Besides, levels of IL-6 and TGF-beta were lowered after treatment in the treatment group, showing a significant difference to those in the control group (P <0.05).

CONCLUSIONQHQ combined with HAT has a definite therapeutic effect on RP. It could efficiently decrease the plasma levels of IL-6 and TGF-beta in patients with RP.

Based on the literatures published from January 1994 to December 2008 on chronic respiratory diseases treated by the therapy of “Dongbing-Xiazhi” (which means treating diseases occurred in winter but treated in summer),the time,region,specific therapies,herbs,and acupoints of these literature were reviewed end analyzed by bibliometric methods to explore its distribution and trends.The research showed that the therapy was effective and widely used in recurrent chronic respiratory diseases.It also demonstrated that such studies as focusing on the scientific design and the mechanism were needed.

The preventative treatment theory is a very important part of traditional Chinese medicine. When this theory is used in the treatment of common cold disease, it focuses on the prevention of common cold disease. The preventative treatment theory is very important and can be applied in the whole process of the treatment common cold disease.

Objective To study the effect of exogenous rhBMP-2(recombinant human bone morpho- genetic protein-2)on the expression of endogenous TGF-?1 during osteogenesis in rabbits.Methods After successfully duplicating experimental rabbit skull defect model,we detected and analyzed the expression of en- dogenous TGF-?1 of the pericranium in different stages by using immunohistochemieal method in both the ex- perimental group and the control group.Results In the experimental group a lot of mesenchymal cells with positive expression of endogenous TGF-?1 of the pericranium aggregated in duramater in the early stage after operation,and the expression level increased rapidly with the differentiation of mesenchymal cells,and reached the peak at 17,19 day postoperation.Positive cell number of TGF-?1 of pericranium was statistically analyzed in both groups at 7,15,21 days,showing significant difference(t-test,P＜0.01 ).Conclusion Exogenous rhBMP-2 can induce and enhance the expression of endogenous TGF-?1 during osteogenesis.

OBJECTIVE To study the differentiation of PC12 cells induced by total salvianolic acid (Tsa) and the mechanism. METHODS MTT assay was used to detect the effect of Tsa 0.01, 0.1 and 1.0 μg·L-1on proliferation of PC12 cells and on the cells damaged by oxygen and glucose deprivation (OGD).The number of projections of PC12 cells was statistically analyzed.Western blotting was applied to detect the levels of microtubule-associated protein2 (MAP-2), extracellular signal-regulated kinase1/2 (ERK1/2), phosphorylated ERK1/2(p-ERK1/2), mitogen-activated protein kinase kinase1/2(MEK1/2) and p-MEK1/2 proteins.MEK inhibitor U0126 was examined for its effect on expressions of p-ERK1/2 and ERK1/2 protein in PC12 cells induced by Tsa 1.0 μg·L-1.RESULTS Compared with normal control group, Tsa 1.0 μg·L-1could promote PC12 cell proliferation, and the survival rate was increased by 90%, but the survival rate of PC12 cells was not affected by Tsa 0.01 or 0.1 μg·L-1. Compared with OGD injured group,PC12 cells injured by OGD could be repaired by Tsa 0.1 or 1.0 μg·L-1,and the survival rate was increased to (47.7±1.8)% and (63.2±13.0)%, respectively (P<0.05, P<0.01). Compared with normal control group,Tsa 0.01,0.1 and 1.0 μg·L-1could promote the growth of PC12 cell projections (P<0.01). Western blotting results showed that Tsa could promote the expressions of MAP-2, p-ERK1/2 and p-MEK1/2 proteins, and this effect could be blocked by U0126 inhibitor (P<0.01). CONCLUSION Tsa can induce the proliferation and differentiation of PC12 cells, the mechanism of which is possibly the activation of p-MEK and p-ERK1/2.

Objective To observe the effect of excretory/secretory products from Trichinella spiralis adult worms(AES)on cecal ligation and puncture(CLP)?induced sepsis in mice. Methods Forty?eight BALB/c mice were randomly divided into 3 groups:a sham operation group(PBS+sham group,Group A),a CLP?induced sepsis group(PBS+CLP group,Group B)and an AES treatment group(AES+ CLP group,Group C). The mice of each group were intraperitoneally injected with 25 μg of AES or PBS only as a control in a total volume of 200μl. Eight mice from each group were selected randomly for survival analy?sis of 96 hours. The other 8 mice in each group were observed for pathological changes in the lung,liver and kidney tissues by HE staining 12 h after CLP,and then determined for the detection of cytokines including TNF?α,IL?1β,IL?6,IL?10 and TGF? βin the sera by ELISA. Results The difference among the survival rates of mice in the 3 groups was statistically significant (χ2=21.16,P<0.05). Compared to Group A(100%),the survival rate of mice in Group B(0)decreased significantly(P<0.05),and also the pathological damage degrees in the lung,liver and kidney tissues of the mice in Group B increased signifi?cantly after CLP. Compared with the mice in group B,the survival rate of those in Group C(70%)increased significantly(P<0.05),and the pathological damage degrees in the lung,liver and kidney tissues of the mice in Group C decreased significantly after the treatment with AES. The differences among the levels of pro?inflammatory cytokines TNF?α(F=27.11,P<0.05),IL?1β(F=18.75,P<0.05)and IL?6(F=100.93,P<0.05)in the sera of the mice in the three groups were statistically signifi?cant. Compared with the mice in Group A,the levels of the 3 cytokines of those in Group B increased significantly(all P <0.05). However,after the treatment with AES,the levels of the pro?inflammatory cytokines of those in Group C decreased signifi?cantly(all P<0.05). The differences among the levels of immunoregulatory cytokines IL?10(F=10.88,P<0.05)and TGF?β(F=11.37,P<0.05)in the sera of the mice in the three groups were also statistically significant. Compared with the mice in Group B,the levels of IL?10 and TGF?β of those in Group C were higher after treatment with AES(both P<0.05). Conclu?sion T. spiralis AES has a therapeutic potential for alleviating sepsis induced by CLP in mice.

Objective:To explore the correlation between serum microRNA(miR)-124 and miR-181c expression and the treatment outcome of Solitaire stent thrombectomy in patients with acute cerebral infarction and its influencing factors.Methods:Eighty-one patients with acute cerebral infarction performed Solitaire stent thrombectomyfrom June 2018 to October 2020 in the Affiliated Hospital of Jining Medical College were selected. The predictive value of miR-124, miR-181c expression in patients with acute cerebral infarction were analyzed.Results:In 81 patients, 21 patients with poor outcome(poor outcome group) and 60 patients with favorable outcome (favorable outcome group). The ratio of age ≥ 60 years in poor outcome group was higher than that in the favorable outcome group: 76.19% (16/21) vs. 46.67% (28/60), there was statistical difference ( χ2 = 5.46, P<0.05). The levels of miR-124, miR-181c before surgery and postoperative 1-day, 7-day in the favorable outcome group were higher than those in poor outcome group: 2.81 ± 0.82 vs. 2.24 ± 0.74, 3.01 ± 1.52 vs. 2.07 ± 1.04, 3.25 ± 1.67 vs. 1.86 ± 0.92; and the levels of miR-181c before surgery and postoperative 1-day, 7-day in the favorable outcome group were lower than those in the poor outcome group: 1.43 ± 0.59 vs. 1.79 ± 0.65, 1.35 ± 0.62 vs. 1.94 ± 0.79, 1.24 ± 0.60 vs. 2.16 ± 1.08, there were statistical differences ( P<0.05). The results of Logistic multivariate analysis showed that the age, the levels of miR-124, miR-181c before operation and postoperative 1-day, 7-day were influencing factors for the treatment outcome of Solitaire stent thrombectomy. The receiver operating characteristic (ROC) curve analysis showed that the area under the curve of miR-124, miR-181c on the postoperative 7-day were 0.806, 0.861, and were higher than those before operation and the postoperative 1-day, the diagnostic sensitivity were 71.43%, 76.19%, the specificity were 88.33%, 85.00%. Conclusions:The expression of miR-124 and miR-181c in the serum of acute cerebral infarction is related to the outcome of Solitaire stent thrombectomy, especially the expression level on the postoperative 7-day has better application value. It can be used to predict the outcome of surgery.
