ABSTRACT
Objective To explore the effect and mechanism of ginsenoside Re on the intestinal mucosa of severe acute pancreatitis (SAP) mice by regulating the Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/ STAT3) pathway. Methods Totally 48 mice were divided into : control group, SAP group, SAP + ginsenoside Re group and SAP + ginsenoside Re + LY2784544 group (n = 12). The mice were intraperitoneally injected with caerulein solution (after fasting for 12 hours, 100 μg/kg, 6 times, injection interval 60 minutes) to establish SAP models. Mice in the SAP+ ginsenoside Re group were intraperitoneally injected with ginsenoside Re (4 mg/kg, 1 time a day for 7 consecutive days). Intraperitoneal injection of 12.7 mg/kg LY2784544 was used to inhibit the JAK2/STAT3 pathway. Pancreatic and intestinal mucosal injury were detected in each group. The wet to dry weight ratio of pancreas, serum amylase and inflammatory factor levels were detected in each group. The intestinal mucosal barrier function was analyzed by detecting the levels of D-lactic acid and fluorescein isothiocyanate dextran (FITC-D). The damage of pancreatic tissue and intestinal mucosa tissue was observed by HE staining. Western blotting was used to detect the levels of apoptotic proteins Bax and Bcl-2 in the intestinal mucosa. The JAK2/STAT3 pathway expression levels in pancreatic tissue and intestinal mucosa tissue were detected by Realtime PCR and Western blotting. Results The pancreatic index, serum amylase, interieukin 6 (IL-6) and tumor necrosis factor a (TNF-a), FITC-D, D-lactic acid, Bax protein levels, JAK2 and STAT3 mRNA and protein levels in the SAP group were significantly higher than those in the control group, while Bcl-2 protein was significantly lower than that in the control group (P<0.05). The Bcl-2 protein of SAP+ginsenoside Re group was significantly higher than that of SAP group, and other indexes were significantly lower than those in SAP group (P<0.05). The Bcl-2 protein of SAP+ginsenoside Re+ LY2784544 group was significantly higher than that of SAP + ginsenoside Re group, and other indexes were significantly lower than those in the SAP+ginsenoside Re group (P<0.05). Conclusion Ginsenoside Re may reduce the pancreatic injury in SAP model mice by inhibiting the JAK/STAT pathway to alleviate the inflammatory response, and may protect the small intestinal mucosal barrier by alleviating pancreatitis and inhibiting the intestinal mucosal JAK/STAT pathway to inhibit cell apoptosis.
ABSTRACT
To analyze the collaborative use and separation reasons of lifting-thrusting and twirling reinforcing and reducing manipulation. Lifting-thrusting manipulation and twirling manipulation are two important contents of acupuncture methods. In traditional acupuncture and moxibustion, the two methods were used in reinforcing and reducing concert, which was mainly related to the therapeutic thought guided by the

Objective To investigate the effects of 654-2 acupoint injection at Zusanli combined with shiatsu at Neiguan acupoint for colonoscopy analgesia. Methods Totally 140 patients underwent colonoscopy were divided into observation group and control group according to the random number table method, with 70 cases in each group. The observation group were given 654-2 acupoint injection at Zusanli (5 mg each side) combined with shiatsu at Neiguan acupoint (the patient to feel the acid, swelling, hemp began to check, until colonoscopy to return to the ileocecum, stop pressing), and the control group were given 654-2 muscle injection (10 mg) 10 min before colonoscopy. The pain scores, checking time and patients'' satisfaction degree of the two groups were compared, and serum beta-endorphin (β-EP) and substance P (SP) level of the two groups before and after examination were compared. Results The pain degrees during colonlscope inserting and passing the sigmoid, splenic flexure of colon of the observation group were significantly lower than those of the control group (P<0.001); testing time was less than that of the control group (P<0.001); patient satisfaction scores were higher than those of the control group (P<0.001); serum β-EP level after examination was higher than that of the control group (P<0.001); SP level was lower than that of the control group (P<0.001). Conclusion 654-2 acupoint injection at Zusanli combined with shiatsu at Neiguan acupoint for colonoscopy analgesia can adjust the serum levels of β-EP and SP, with obvious analgesic effect, which can shorten the testing time.
ABSTRACT
By using rice SSRP, RAPD and AFLP molecular markers, the genome of rice transgenic line "Minghui 63-Xa21" was analyzed. 32 SSRP primers, 42 RAPD primers and 8 AFLP primers could produce obvious PCR bands in the analysis of at least 12 individual plants selected randomly from "Minghui 63-Xa21" T3 generation. Totally 550 PCR bands, equivalent to 550 genomic sites, were detected. Different individual plants of the transgenic homozygous line displayed almost the same PCR pattern. Compared with the control "Minghui 63", no difference was found in their PCR patterns. This indicated that the introduction of Xa21 into the genome of "Minghui 63" did not change these 550 genome sites and their heredity. Very few variant PCR bands were observed in some individual plants from both "Minghui 63-Xa21" and "Minghui 63". However, the variant percentage was equivalent between the transgenic line and the non-transgenic control line.
