Objective To investigate the effects of erythropoietin (EPO) on complement 3a (C3a)-induced renal tubular epithelial to mesenchymal transition. Methods The HK-2 cells were divided into 6 groups namely control group,EPO group,TGF-β group,TGF-β+EPO group,C3a group and EPO+C3a group.The mRNA and protein expressions of α-SMA,E-cadherin and C3 were investigated by RT-PCR,Western blot and immunofluorescence respectively. Results Compared with control group and EPO group,the mRNA and protein expressions of α-SMA in HK-2 cells were up-regulated after the intervention of C3a or TGF-β (all P<0.05).On the contrast,the mRNA and protein expressions of E-cadherin were down-regulated(P<0.05),the mRNA and protein expressions of C3 were enhanced (all P<0.05).However,all those above effects of C3a or TGF-β were inhibited after the intervention of EPO (all P<0.05). Conclusion EPO is capable of suppressing the epithelial to mesenchymal transition induced by C3a.

OBJECTIVETo explore the effects of principal-subordinate acupoints combination on improving myocardial ischemia, and the gene regulatory pathways for the protection of myocardial ischemia.
METHODSAccording to the random number table method, 70 SPF Wistar male rats were divided into a normal group, a model group, a LY294002 group, an insulin-like growth factors-1(IGF-1) group, a Neiguan group, an acupoint combination group and an acupoint combination + LY294002 group, 10 rats in each one. Rats in the normal group were injected with 0.9% NaCl solution, while rats in the remaining groups were treated with abdominal subcutaneous injection of isoroterenol hydrochloride to establish the rat model of myocardial ischemia. Rats in the LY294002 group and IGF-1 group were treated with injection of LY294002 solution and IGF-1 solution for 14 days. Rats in the Neiguan group were treated with electroacupuncture (EA) at "Neiguan" (PC 6) by using Han-200 EA apparatus for 10 min per treatment. Rats in the acupoint combination group were treated with EA at "Neiguan" (PC 6), "Zusanli" (ST 36) and "Guanyuan" (CV 4) by using Han-200 EA apparatus for 10 min per treatment. Rats in the acupoint combination + LY294002 group were treated with LY294002 solution for 14 days, and EA at "Neiguan" (PC 6), "Zusanli" (ST 36) and "Guanyuan" (CV 4) was given before model establishment, once a day for 21 days. EA pretreatment was given before model establishment in all acupuncture groups. The heart rate (HR) and ST segment voltage were detected before and after treatment; the myocardial pathological morphology was observed by HE staining; the expressions of P13K mRNA and Akt mRNA were tested.
RESULTSAfter modeling, HR and ST segment voltage in all intervention groups were higher than those in the normal group (all P < 0.01); after the intervention, the HR and the ST segment voltage in the acupoint combination group, IGF-1 group and IGF-1 group were improved (P < 0.01, P < 0.05), which was more significant in the acupoint combination group and Neiguan group (all P < 0.01). As for the myocardial pathological morphology, obvious myocardial ischemia was observed in the model group, and that in the LY294002 group was the most serious, and that in the acupoint combination+ LY294002 group was moderate. After intervention, the myocardial pathological damage in the IGF-1 group, Neiguan group and acupoint combination group was significant improved, which was more significant in the IGF-1 group and acupoint combination group. As for the expression of PI3K mRNA and Akt mRNA, compared with normal group, the expression of PI3K mRNA was increased in the remaining groups after modeling (P < 0.01, P < 0.05), which was more significant in the IGF-1 group and acupoint combination group (all P < 0. 01). The expression of Akt mRNA in the LY294002 group and acupoint combination + LY294002 group was reduced (P < 0. 01, P < 0.05), while that in the remaining groups was increased (P < 0.01, P < 0.05), which was more significant in the IGF-1 group and acupoint combination group (all P < 0.01).
CONCLUSIONThe principal-subordinate acupoints combination could improve heart rate and ST segment voltage in rats with chronic myocardial ischemia, reduce myocardial pathological damage, which is superior to single selection of "Neiguan" (PC 6). The PI3K/Akt signaling pathway may be involved in the regulation mechanism of principal-subordinate acupoints combination for the protection of chronic myocardial ischemia.

Objective:To investigate the effects of survival status in Stanford type A aortic dissection (TAAD) patients over 70 years old by different treatment methods.Methods:The clinical data of 151 TAAD patients over 70 years old from January 2012 to January 2022 in the Affiliated Hospital of Jining Medical University were retrospectively analyzed. Among them, 60 patients were treated with surgery (surgical treatment group), and 91 patients with conservative method (conservative treatment group). The duration of hospitalization and complications (including pericardial effusion, acute myocardial infarction, pericardial tamponade, shock, stroke, mesenteric ischemia and acute renal failure) were recorded. The patients were followed up within 30 d after the onset of illness. The survival status was recorded. The multivariate Cox regression analysis was used to analyze the independent risk factors of death in TAAD patients over 70 years old.Results:The duration of hospitalization in surgical treatment group was significantly longer than that in conservative treatment group: 14.00 (7.00, 19.75) d vs. 5.00 (2.00, 10.00) d. The incidences of pericardial tamponade, shock and acute renal failure: 1.7% (1/60) vs. 13.2% (12/91), 8.3% (5/60) vs. 24.2% (22/91) and 0 vs. 9.9% (9/91), with statistical differences ( P<0.01 or <0.05), but no statistical differences in the incidences of pericardial effusion, acute myocardial infarction, stroke, mesenteric ischemia between two groups ( P>0.05). Patient follow-up for 30 d, the mortality rate in surgical treatment group was significantly lower than that in conservative treatment group: 15.0% (9/60) vs. 46.2% (42/91), with statistical difference ( χ2 = 15.69, P<0.01). The multivariate Cox regression analysis result showed that conservative treatment, female, increased aortic root diameter and concomitant stroke were the independent risk factors of death in TAAD patients over 70 years old ( RR = 2.311, 2.135, 1.051 and 3.737; 95% CI 1.056 to 5.057, 1.083 to 4.212, 1.004 to 1.100 and 1.393 to 10.026; P<0.05 or <0.01). Conclusions:The early surgical treatment is recommended in TAAD patients over 70 years old with surgical indications.

Objective To investigate the effect of Brahma-related gene 1 (Brg1) on mucus hypersecretion in the airway of asthmatic mice and explore the mechanism. Methods Female C57bl/6 mice aged 6-8 weeks were randomized into wild-type control group, wild-type asthma group, Brg1-/-group with Brg1 gene knockdown in type II alveolar epithelial cells, and Brg1-/-+asthma group (n=10). The mice in asthma group and Brg1-/-+asthma group were sensitized with ovalbumin (OVA) to establish asthmatic models. PAS staining was used to determine the number of goblet cells and mucus secretion in the airway. Real-time PCR was used to detect the expression of MUC5AC mRNA in the lung tissues. The levels of mucin MUC5AC and interleukin-13 (IL-13) in the bronchoalveolar lavage fluid (BALF) were detected with ELISA and immunohistochemistry, and the expressions of STAT6 and p-STAT6 in the lung tissue were detected using Western blotting. Results Compared with the control mice, wild-type asthmatic mice showed obvious mucus hypersecretion and increased MUC5AC mRNA in the airway with significantly increased IL-13 and MUC5AC levels in the BALF and activation of p-STAT6 in the lung tissues (P<0.05). In the transgenic mice with Brg1 gene knockdown, airway mucus secretion and MUC5AC mRNA expression was significantly reduced following OVA challenge compared with those in the wild-type asthmatic mice; IL-13 and MUC5AC levels in the BALF and p-STAT6 expression in the lung tissues were also significantly decreased in the transgenic mice (P<0.05). Conclusion Brg1 gene knockdown in type II alveolar epithelial cells alleviates OVA-induced airway mucus hypersecretion and reduces the expression of MUC5AC in C57bl/6 mice possibly by inhibiting STAT6 activation, suggesting the role of Brg1 in promoting asthmatic airway mucus hypersecretion.
