Objective:To observe the effect of moxibustion on the mRNA and protein expressions of heat-shock protein 70 (HSP70) in gastric cancer-bearing rats. Methods: A total of 40 healthy Sprague-Dawley (SD) rats were adaptively fed for one week. The gastric cancer model was prepared by Walker-256 cancer tissue transplantation. After 7 d, 10 rats were randomly selected to verify the successful modeling, and the remaining 30 rats were divided into a model group, a moxibustion group and an infrared group by the random number table method, with 10 rats in each group. After enrollment, the moxibustion group received suspended moxibustion at Zhongwan (CV 12), Guanyuan (CV 4) and bilateral Zusanli (ST 36), (the first group of acupoints) on the 1st day, and suspended moxibustion at bilateral Pishu (BL 20) and Weishu (BL 21), (the second group of acupoints) on the 2nd day, 20 min each time, once a day. Moxibustion was alternately performed every other day at the two groups of acupoints for 21 d. From the day of enrollment, rats in the infrared group were irradiated with the infrared radiation at the stomach area on the 1st day, and at the T12-T13 interspinous region on the 2nd day, 20 min each time, once a day, and the two locations were alternately irradiated every other day for 21 d. During the treatment, rats in the model group were intervened by grasping and fixation without treatment. At the end of the treatment, blood was collected from the inner eye orbit, and the HSP70 expression in peripheral blood was determined by enzyme linked immunosorbent assay (ELISA). Rats were sacrificed, the tumor volume and growth inhibition rate were measured. The position and changes of HSP70 in gastric cancer were observed by streptavidin-perosidase (SP); HSP70 protein expression was determined by ELISA; HSP70 mRNA expression in cancer tissues was determined by reverse transcription-polymerase chain reaction (RT-PCR) assay. Results: In comparison of the model group, the volume growth of the gastric cancer in the moxibustion group was significantly restricted (P＜0.01); the volume growth inhibition rate in the moxibustion group was 37.93%; the HSP70 expression in peripheral blood and the cancer tissues was significantly increased (both P＜0.01); the expression of HSP70 mRNA and HSP70 content in gastric tumor were both obviously increased in the moxibustion group (P＜0.01); and a large amount of HSP70 was released to the outside of cancer cells in the moxibustion group. In comparison of the model group, the volume growth of the gastric cancer in the infrared group was slightly restricted (P＜0.05) with a volume growth inhibition rate of 15.89%; the HSP70 expression in the infrared group was increased significantly in peripheral blood (P＜0.01) and in the gastric cancer tissues (P＜0.05); more HSP70 was released outside of the cancer cells in the infrared group. In comparison of the infrared group, the volume growth of gastric cancer was more restricted in the moxibustion group (P＜0.05), and the HSP70 expression in the gastric cancer tissues was also higher (P＜0.05); more HSP70 was released outside of the cancer cells in the moxibustion group. Conclusion: Moxibustion and infrared treatment inhibit the gastric cancer growth in the gastric cancer-bearing rats, up-regulate the HSP70 expression in gastric cancer tissues, and promote the production and extracellular release of HSP70, and the effect of moxibustion is more obvious.

To investigate the cardioprotective effect of formononetin (FMN) on no-reflow (NR) after myocardial ischemia-reperfusion and its molecular mechanism based on integrated pharmacology and experimental verification, firstly, human breast cancer MCF-7 cells and myocardial NR rats were used to confirm the estrogenic activity and the effect of alleviating NR of FMN, respectively. Male SD rats were divided into Sham, NR, FMN (20 mg·kg^-1) and sodium nitroprusside (SNP, 5.0 mg·kg^-1) groups, which were administered once a day for one week, the experiment was approved by the Ethics Committee of Tianjin University of Traditional Chinese Medicine (TCM-LAEC2019095). The pharmacological analysis and in vivo study of NR rats were integrated to reveal the mechanism of FMN improving NR. The results showed that FMN had estrogenic effect and reduced NR by improving cardiac structure and function, reducing NR, ischemic myocardial area and pathological injury of cardiomyocytes. Integrated pharmacology predicts that the mechanism of FMN improving NR is mainly related to phosphatidyinositol-3-kinase-protein kinase B (PI3K-Akt) signal pathway. Phytoestrogens play a role in cardiovascular protection mainly by activating G protein-coupled estrogen receptor (GPER). GPER is also an important regulator in the upstream of PI3K-Akt signaling pathway. This study found that FMN can significantly activate GPER, p-PI3K, p-Akt and phospho-endothelial nitric oxide synthase (p-eNOS). It has good binding ability with GPER and eNOS protein. In this study, through the integration of pharmacology and experimental evaluation, it is revealed that FMN activates PI3K/Akt/eNOS signal pathway by activating GPER, thus significantly improving NR.

OBJECTIVETo explore the immune mechanism of moxibustion on protecting gastric mucosa injury.

METHODSForty healthy SD rats were randomly divided into four groups: a blank group, a model group, a moxibustion acupoint group and a moxibustion non-acupoint group, 10 rats in each one. Eight days before model establishment, moxibustion at "Zusanli" (ST 36), "Zhongwan" (CV 12), "Guanyuan" (CV 4), "Pishu" (BL 20) and "Weishu" (BL 21) was applied in the moxibustion acupoint group while these acupoints' controlled points were selected in the moxibustion non-acupoint group, and no treatment was given in the model group, once a day in three groups for continuous 16 days. The helicobacter pylori (Hp) model was established by intragastric administration of Hp. HE staining microscopic examination was used to observe inflammation severity in gastric mucosa, and enzyme-linked immunosorbent assay (ELISA) was adapted to measure content of heat shock protein (HSP) 72, TNF-alpha and IL-1beta, and real-time quantitative PCR was used to measure the expression of TLR2 mRNA, TLR4 mRNA, CD14 mRNA and MyD88 mRNA in peripheral blood mononuclear cells, and western blot method was used to measure content of NFkappaB and IkappaBalpha in peripheral blood mononuclear cells.

RESULTSCompared with the blank group, the expression of HP could be seen in the smear of gastric mucosa by Gram's staining in the model group; the inflammation severity score was obviously increased as well as content of serum HSP 72 and TNF-alpha and IL-1beta in gastric tissue; and expression of TLR2, 4 mRNA, CD14 mRNA, MyD88 mRNA, NFkappaB was increased (P < 0.01), but the expression of IkappaBalpha was reduced (P < 0.05). After the moxibustion, the inflammation severity score was reduced in the moxibustion acupoint group, and the content of serum HSP 72 was increased, and the expression of TNF-alpha and IL-1beta in gastric tissue and expression of TLR2 mRNA, TLR4 mRNA, CD14 mRNA, MyD88 mRNA and NFkappaB were reduced (P < 0.01), but the expression of IkappaBalpha was increased (P < 0.05). The differences between the moxibustion non-acupoint group and the model group were not significant (P > 0.05).

CONCLUSIONThe pretreatment of moxibustion at acupoints could induce the over expression of serum HSP 72. By combining TLR 2 and 4 receptors to trigger receptor signal transduction pathways, the releases of downstream signal substances are regulated; as a result, the releases of related immune substances are regulated to relieve the gastric mucosa injury of rats with HP gastritis.

OBJECTIVETo observe the effect of CKJ Recipe (consisting of Cordyceps sinensis polysaccharide, amygdaloside, and gypenosides) containing serum on the activation of rat primary hepatic stellate cells (rHSCs) and to explore its pharmacological mechanism.

METHODSrHSCs were isolated form liver and cultured for four days. Then they were divided into the normal control group, the model group, and the CKJ group. rHSCs in the model group and the CKJ group were treated with 2.5 ng/mL transforming growth factor beta1 (TGF-beta1) in serum-free DMEM for 24 h. Serum free DMEM (containing no TGF-beta1) was taken as the control for the normal control group. rHSCs in the CKJ group were treated with 5% CKJ-containing serum for 24 h. rHSCs in the other two groups were treated with 5% blank serum for 24 h.The protein expression level of a smooth muscle actin (alpha-SMA) was determined using high throughput screening (HCS) and Western blot. mRNA expression levels of alpha-SMA, collagen I (Col-I), platelet-derived growth factor receptor beta (PDGF-betaR), TGF-beta1, transforming growth factor beta receptor 1 (TGF-betaR1), and transforming growth factor beta receptor 2 (TGF-beta R2) were detected using quantitative RT-PCR.

RESULTSCompared with the normal control group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-betaR1, and TGF-betaR2 significantly increased in the model group (P<0.05, P<0.01). Compared with the model group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-beta1, and TGF-beta R2 significantly decreased in the CKJ group (P<0.05, P<0.01).

CONCLUSIONCKJ containing serum could inhibit the protein expression level of o-SMA, which was probably related with inhibiting TGF-beta1 and its related receptors.

Objective:To observe the effect of moxibustion on T lymphocyte subsets in peripheral blood of rats with gastric cancer. Methods:Sixty healthy Sprague-Dawley (SD) rats were adaptively fed for one week. By the random number table method, 10 rats were randomly selected as a blank group, and 12 rats were randomly selected to simulate the tumor transplantation process; after transplantation, 10 rats were randomly selected as a sham operation group. The remaining 38 rats were used to prepare gastric cancer models by gastric transplantation of the Walker-256 tumor tissue; 8 rats were randomly selected to verify the successful modeling after 7 d; the remaining 30 rats were randomly divided into a model group, a moxibustion group and an infrared group by the random number table method, with 10 rats in each group. From the first day of enrollment, the rats in the moxibustion group received mild moxibustion at Zhongwan (CV 12), Guanyuan (CV 4) and bilateral Zusanli (ST 36) (the first group) and bilateral Pishu (BL 20) and Weishu (BL 21) (the second group), and the two groups of acupoints were alternated every other day. The rats in the infrared group received infrared radiation on the stomach area and the area on the back between the T12-T13 spinous processes, the two areas were alternated every other day. Rats in the moxibustion group and the infrared group were treated for 20 min each time, once a day for 21 d. Rats in the blank group, the sham operation group, and the model group were simultaneously grasped and fixed, and no other treatment was performed. After 21 d of intervention, the rats in each group were fasted for 12 h, and blood was collected from the orbits. The numbers of CD3+, CD3+CD4+, CD3+CD8+ T lymphocytes in peripheral blood were determined by flow cytometry, and the ratio of CD3+CD4+/CD3+CD8+ was calculated. The rats were sacrificed and the thymus was dissected under sterile conditions to calculate the thymus index. Results:Compared with the blank group, the thymus index, peripheral blood CD3+, CD3+CD4+, CD3+CD8+ and CD3+CD4+/CD3+CD8+ ratio in the sham operation group did not change significantly (allP>0.05). Compared with the blank group, the thymus index of the model group was increased (P<0.05), the CD3+ and CD3+CD8+ T lymphocytes were increased (bothP<0.01), and the CD3+CD4+/CD3+CD8+ ratio was decreased (P<0.05). Compared with the model group, the thymus index of the moxibustion group was increased (P<0.01), and CD3+, CD3+CD4+ and CD3+CD8+ T lymphocytes and the ratio of CD3+CD4+/CD3+CD8+ in peripheral blood were increased (allP<0.05). Compared with the infrared group, the thymus index of the moxibustion group was significantly increased (P<0.05), the CD3+ and CD3+CD4+ T lymphocytes in the peripheral blood were significantly increased (bothP<0.01), and the CD3+CD8+ was increased (P<0.05). Conclusion:Moxibustion can significantly increase the thymus index of gastric cancer-bearing rats and activate CD3+CD4+ and CD3+CD8+ T lymphocytes in peripheral blood.

Objective: To investigate the mechanisms of electroacupuncture (EA) at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) in intervening diabetic gastroparesis (DGP) based on calcium-activated chloride channel. Methods: Forty Sprague-Dawley rats were randomly divided into four groups, including a normal control group (group A), a model group (group B), an EA group (group C) and a metoclopramide group (group D), with 10 rats in each group. A single intraperitoneal injection of 2％ streptozotocin (STZ) combined with 8-week high-glucose high-fat diet was used to establish a DGP rat model. After intervention, gastrointestinal propulsive rate was observed; the expression level of transmembrane protein 16A (TMEM16A) was examined by immunohistochemistry; the Ca2+ concentration in interstitial cells of Cajal (ICCs) was detected by immunofluorescence; and whole-cell patch-clamp technique was applied to detect the current intensity of calcium-activated chloride channel (ICaCC) in ICCs in gastric antrum. Results: After modeling, the blood glucose levels in group B, group C and group D were significantly increased compared with group A (all P<0.01); after intervention, compared with group B, the blood glucose levels in group C and group D were significantly decreased (P<0.05, P<0.01); the intra-group comparison of blood glucose level between after modeling and after intervention found significant difference only in group C (P<0.01). The gastrointestinal propulsive rates in group B, group C and group D were significantly different from that in group A (P<0.01 or P<0.05); the gastrointestinal propulsive rates were markedly higher in group C and group D than in group B (P<0.01, P<0.01). The expressions of TMEM16A in group B and group C were decreased compared with group A (P<0.01, P<0.05); the expressions of TMEM16A in group C and group D were increased compared with group B (P<0.01, P<0.05). The fluorescence intensity of Ca2+ was significantly lower in group B than in group A (P<0.01); the fluorescence intensity of Ca2+ was significantly higher in group C and group D than in group B (P<0.01, P<0.05). ICaCC in ICCs in group B was significantly decreased compared with group A; ICaCC in group C and group D were increased compared with group B. Conclusion: EA at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) can significantly improve gastrointestinal motility in DGP rats by up-regulating the ICaCC in ICCs.

Objective To explore the relationship between SpO2/FiO2(S/F) and PaO2/FiO2(P/F) so as to determine the possibility of ARDS severity identification based on noninvasive parameters. Methods The physiological parameters of corresponding patients were acquired from Medical Information Mart for Intensive Care (MIMIC-Ⅲ),and then divided into a training set and a test set randomly.In the training set the linear relationship between lg(S/F)and lg(P/F)was established with generalized linear regression model,and a log linear regression model was formed with the optimal regression equation;the linear relationship between lg(S/F)and lg(P/F)was compared with that between S/F and P/F.In the test set,the two models were compared on the identification of ARDS in case P/F values were 100(mild ARDS),200(moderate ARDS)and 300(severe ARDS)respectively.Results In the training set(n=61 634)the linear relationship between lg(S/F)and lg(P/F)was deduced as lg(S/F)=1.277+0.437×lg(P/F) (r=0.66,P<0.000 1),and the S/F thresholds in case P/F values were 100,200 and 300 respectively were 131,201 and 271.In the test set (n=26 758)the identification effect was verified with the acquired S/F thresholds,which proved better than that of traditional regression model.Conclusion Noninvasive parameter SpO2/FiO2can replace PaO2/FiO2for the auxiliary diagnosis of ARDS in case the result of blood gas analysis is absent.
