In recent years,endoscopic ultrasound has been widely used in the diagnosis of submucosal disease of the esophagus,stomach,colon and other organs.However,the small intestine is still unable to diagnose.Intra-small intestinal ultrasonography primary layer of the small intestine diseases can be used to accurately determine the depth of invasion,The result is to improve the diagnosis rate.But mode of operation,equipment selection and diagnostic criteria still need to study.

Objective To study the application of intra-luminal ultrasonography (intra-small intestinal ultrasonography,ISIU) in demonstration of normal small intestine and diagnosis of small bowel lesions.Methods From December 2011 to December 2012,ISIU was performed in 50 patients who were screened by capsule endoscopy,gastroscopy,colonoscopy,and double-balloon enteroscopy to observe the normal tissue structures and lesions of the small intestine.Additional abdominal ultrasound (US) and spiral CT (SCT) were applied in patients with identified lesions in small intestine.Results ISIU was completed in 47patients out of 50 enrolled ones.A total of 10 lesions in small intestine were detected,all of them were identified by ISIU,while in which only 1 was found by US and 3 by SCT.Normal small intestinal wall demonstrated 6 layers under ISIU,with slight difference between jejunum and ileum.Conclusion ISIU provides high-resolution image of the structure at all levels of the normal small intestine,and can clearly observe lesion source and internal echo,and thus help to improve the rate of diagnosis of diseases of the small intestine.

Objective To study the levels of soluble thrombomodulin (sTM)in patients with acute coronary syndrome (ACS) and evaluate its clinical significance. Method Measured the sTM levels with enzyme linked immunosorbent assay, and described the characteristics of coronary arteriography, risk factors of coronary heart disease, and adverse events in a case-control study of 48 ACS patients (ACS group)and 10 normal people (control group). Results The level of sTM in ACS group was (3.67±1.71) μg/L, and (2.34±0.43)μg/L in control group (P<0.05). The level of sTM in the patients of risk factors or impaired vessels number more than 2 increased significantly than those in the patients of risk factors or impaired vessols number inferior or equal to 2, (4.93±2.76) μg/Lvs (3.13±0.81) μg/L, P<0.05, (4.60± 2.83) μg/L vs (2.91±0.23) μg/L, P < 0.05 respectively. The incidence of cardiac events in the patients of sTM more than 3.2 μg/L (70.0%)was higher significantly than that in the patients of sTM inferior or equal to 3.2 μg/L(35.7%), P< 0.05. Conclusions The levels of sTM are valuable markers to evaluate the impaired degree and scope of endothelial cells in ACS. They are also associated with the number of risk factors, and useful in predicting the extent and prognosis of the disease.

Objective: To investigate the effect of chromium picolinate on egg production, egg quality, serum biochemical indices and immune response. Methods: A total of 120 49 w old Beijing Red commercial layers were randomly allotted to one of five treatments, and fed a basal corn soybean meal diet and the basal diet supplemented with 0.4,2.0,10.0 or 20.0 mg/kg Cr as chromium picolinate under heat stress for 30 days.Results: Cr increased average egg weight(P0.20) on egg yield, feed intake and feed/egg ratio. Added Cr at 0.4 ,2.0,10.0 mg/kg enhanced (P

0.10)between the two Cr sources was observed in all indices studied; Cr level affected the relative weight of spleen (P

Objective: : Nicotinamide mononucleotide adenylyl transferase 2 (NMNAT2) is a crucial factor for the survival of neuron. The role of NMNAT2 in damage following traumatic brain injury (TBI) remains unknown. This study was designed to investigate the role of NMNAT2 in TBI-induced neuronal degeneration and neurological deficits in rats. Methods: : The TBI model was established in Sprague-Dawley rats by a weight-dropping method. Real-time polymerase chain reaction, western blot, immunofluorescence, Fluoro-Jade C staining, and neurological score analyses were carried out. Results: : NMNAT2 mRNA and protein levels were increased in the injured-side cortex at 6 hours and peaked 12 hours after TBI. Knocking down NMNAT2 with an injection of small interfering RNA in lateral ventricle significantly exacerbated neuronal degeneration and neurological deficits after TBI, which were accompanied by increased expression of BCL-2-associated X protein (Bax). Conclusion : NMNAT2 expression is increased and NMNAT2 exhibits neuroprotective activity in the early stages after TBI, and Bax signaling pathway may be involved in the process. Thus, NMNAT2 is likely to be an important target to prevent secondary damage following TBI.

Objective: To evaluate and compare the clinical value of early enteral nutrition (EEN) and total parenteral nutrition (TPN) af-ter esophageal cancer surgery. Methods: We retrospectively analyzed 237 patients who underwent esophageal cancer surgery at Bei-jing Shijitan Hospital from March 2011 to March 2019. They were assigned into two groups based on the postoperative nutritional sup-port used: EEN (136 cases) and TPN (101 cases). Nutritional status, liver function, recovery of gastrointestinal function, days of hospital-ization, and postoperative complications were compared between the two groups after propensity score matching. Results: Using 1 :1 nearest neighbor matching, we successfully matched 91 pairs of patients. The prealbumin (PA) level was significantly higher in the EEN group than in the TPN group 7 days after surgery (P<0.05); however, there was no significant difference in albumin (ALB) level before surgery, 3 or 7 days after surgery. Additionally, the levels of ALT and AST in the EEN group were significantly lower than those in the TPN group 3 and 7 days after surgery (P<0.05). The incidence of acid reflux, vomiting, and diarrhea in the EEN group was higher than that in the TPN group, while the incidence of pulmonary edema and pulmonary infection was lower in the EEN group than in the TPN group (P<0.05). Conclusions: Compared with TPN, EEN is associated with a high incidence of acid reflux, vomiting, and diarrhea after esophageal cancer surgery, but it has a lower impact on liver function. EEN can promote the recovery of intestinal function, improve nutritional indicators, and shorten hospitalization time.

Objective To analyze the dosimetric features of chest wall radiotherapy after modified radical mastectomy for left breast cancer using the beam’s eye view (BEV) in intensity-modulated radiation therapy (B-IMRT). Methods A total of 13 patients treated with modified radical mastectomy for left breast cancer in the Liaocheng People’s Hospital from May 2020 to November 2020 were recruited. They were treated with postoperative radiotherapy using the plans of B-IMRT or tangential fields in intensity-modulated radiation therapy (T-IMRT). The mean dose, conformity index and homogeneity index of the target field, and dose volume parameters of left lung and heart were compared between two groups. Results Compared with those of T-IMRT group, B-IMRT significantly improved the conformity and homogeneity of the target field (P < 0.05), and their mean dose of target field was similar. In addition, V₅, V₁₀, V₂₀, V₃₀ and D_mean of the left-side lung, and V₅, V₁₀, V₃₀ and D_mean of the heart in B-IMRT group were significantly reduced compared with those of T-IMRT group (P < 0.05). In comparison to those of T-IMRT, B-IMRT decreases V₅, V₁₀, V₂₀, V₃₀ and D_mean of the left-side lung by 9.23%, 13.29%, 9.54%, 8.28% and 10.35%, respectively, which decreases V₅, V₁₀, V₃₀ and D_mean of the heart by 27.62%, 29.72%, 21.45% and 24.88%, respectively. Conclusion Compared with T-IMRT planning, B-IMRT presents dosimetric advantages in the conformity and homogeneity of the target field in the postoperative radiotherapy of patients treated with modified radical mastectomy for left breast cancer, especially in reducing the radiation dose and volume of the heart and lungs.

Renal tubulointerstitial fibrosis is the common ending of progressive renal disease. It is worth developing new ways to stop the progress of renal fibrosis. Peroxisome proliferator-activated receptor-γ (PPARγ) agonists have been studied to treat diabetic nephropathy, cisplatin-induced acute renal injury, ischemia reperfusion injury and adriamycin nephropathy. In this study, unilateral ureteral obstruction (UUO) was used to establish a different renal fibrosis model. PPAR? agonist pioglitazone was administrated by oral gavage and saline was used as control. At 7th and 14th day after the operation, mice were sacrificed for fibrosis test and T lymphocytes subsets test. Unexpectedly, through MASSON staining, immunohistochemistry for α-SMA, and Western blotting for a-SMA and PDGFR-β, we found that pioglitazone failed to attenuate renal fibrosis in UUO mice. However, flow cytometry showed that pioglitazone down-regulated Th1 cells, and up-regulated Th2 cells, Th17 cells and Treg cells. But the Th17/Treg ratio had no significant change by pioglitazone. Real-time PCR results showed that TGF-β and MCP-1 had no significant changes, at the same time, CD4(+) T cells associated cytokines were partially regulated by pioglitazone pretreatment. Taken together, pioglitazone failed to suppress renal fibrosis progression caused by UUO.
