Objective To study the effects of 16-detector row CT on the measurement of abdominal fat in diabetic patients. Methods Forty patients with diabetes mellitus were enrolled in this study(diabetes group), 40 healthy subjects served as control (control group). Several indexes of abdominal adipose were measured with 16-slice spiral CT including the volume of abdominal adipose (VAA)ranging within 2.5cm of the umbilicus, volume of visceral adipose (VVA) and volume of subcutaneous adipose (VSA). Meanwhile, visceral adipose area (VA) and subcutaneous adipose area (SA) were measured also. Results The volumes of VAA,VVA,VSA,VA,SA,VVA/VSA and VA/SA in diabetes group were significantly larger than that in control group (all P＜0.05).Conclusion Diabetes patients have the accumulation of abdominal fat.

Objective: To explore the application effect of preoperative administration of immunomodulating enteral nutrition for gastric cancer. Methods: From January 2016 to December 2017, 90 cases with gastric cancer in the Second People′s Hospital of Lianyungang were selected and randomly divided into observation group, control group A and control group B, with 30 cases in each group.The observation group was given enteral nutrition emulsion(TPFT, Ruineng) before and after operation, the control group A was given Ruineng before operation and the enteral nutrition emulsion(TP, Ruisu) after operation, the control group B was given Ruisu before operation and Ruineng after operation.The recovery, serum markers of nutritional status and immune function were evaluated and compared, and the postoperative situations were observed. Results: There were no statistically significant differences in the total protein, albumin, prealbumin and transferrin among the three groups during admission, 1 day before operation and 5 days after operation(all P>0.05). There was no statistically significant difference in immune indicators among the three groups during admission and 1 day before operation(all P>0.05). At 5 days after operation, IgA, IgM, IgG, CD₄⁺ and CD4/CD8 in the observation group were (2.9±0.6)g/L, (1.4±0.4)g/L, (12.4±0.9)g/L, (37.4±5.1)%, (2.2±0.7), respectively, which were significantly higher than those in the control group A[(2.3±0.8)g/L, (1.1±0.6)g/L, (10.8±0.8)g/L, (34.2±4.8)%, (1.7±0.8), respectively, t=3.324, 2.250, 7.100, 2.506, 2.660, all P<0.05], the IgA and CD4/CD8 in the observation group were higher than those in the control group B[(2.6±0.8)g/L, (1.9±0.7), t=2.021, 2.127, all P<0.05]. The postoperative exhaust time of the observation group, control group A and control group B were (56.4±7.8)h, (78.6±10.4)h, (60.7±10.6)h, respectively, and the postoperative exhaust time of the observation group was significantly shorter than that of the control group A(t=9.323, P<0.05). There was no statistically significant difference in the gastrointestinal symptoms and postoperative complications among the three groups (P>0.05). Conclusion In perioperative period, immunomodulating enteral nutrition has little effect on the nutritional indicators of patients with gastric cancer and the incidence of postoperative complications, but it can improve the immune function.

Objective: To compare the effects of laparoscope and open complete mesocolic excision (CME) in the treatment of right colon cancer. Methods: The retrospective case-control study was adopted.The clinical data of 139 patients with right colon cancer who underwent CME at the Second People's Hospital of Lianyungang from January 2014 to November 2017 were collected.The patients were divided into laparoscopy group(55 cases) and open group(84 cases). The postoperative recovery and oncology efficacy were compared. Results: The operation time in the laparoscopy group[(172.8±25.9)min]was longer than that in the open group[(142.3±20.6)min](t=7.387, P<0.05), but the blood loss of the laparoscopy group[(111.6±36.7)mL] was less than that in the open group[(150.1±61.1)mL](t=4.017, P<0.05). There was no statistically significant difference in numbers of lymph nodes harvested.Compared with open group, there were advantages in the laparoscopy group such as less anal exhaust time, less postoperative eating liquid diet time and shorter hospitalization time, the differences were statistically significant (t=4.695, 5.517, 4.642, all P<0.05). There was no statistically significant difference in postoperative complication rate (P>0.05). There were no statistically significant differences in the cumulative recurrence rate, cumulative survival rate and cumulative survival rate between the two groups after 3 years (all P>0.05). Conclusion Laparoscopic CME is minimally invasive and quick recovery, and laparoscopic CME has the same oncologic clearance effects, and is worthy of clinical application.

Objective To observe the effects of Jianpi Qutan Huayu Prescription on oxidative stress and inflammatory response in mini-pigs with atherosclerosis(AS);To explore its mechanism based on the NOX5-ERK1/2 signaling pathway.Methods Twelve Bama mini-pigs were randomly divided into control group,model group,and Jianpi Qutan Huayu Prescription low-and high-dosage groups,with 3 pigs in each group.A high-fat diet was used to feed for 24 weeks to construct an AS model,and the treatment group was also supplemented with Jianpi Qutan Huayu Prescription in the feed.The general condition of mini-pigs(body length,abdominal circumference,body mass,food intake,and fecal water content)was measured at week 0,16,and 24 of administration,HE staining was used to observe the morphology of aortic tissue,while oil red O staining was used to observe lipid deposition in aortic and myocardial tissue,transmission electron microscopy was used to observe the ultrastructure of aortic tissue,and a fully automated biochemical analyzer was used to detect serum contents of TC,HDL-C,and LDL-C.ELISA was used to detect the contents of serum reactive oxygen species(ROS),interleukin(IL)-6,IL-10,tumor necrosis factor(TNF)-α,hypersensitivity-C-reactive protein(hs-CRP),vascular cell adhesion molecule-1(VCAM-1),and intercellular adhesion molecule-1(ICAM-1).Western blot was used to detect the expressions of NADPH oxidase 5(NOX5),extracellular signal regulated kinase 1/2(ERK1/2),p-ERK1/2,VCAM-1,and proliferating cell nuclear antigen(PCNA)proteins.Results Compared with the control group,the abdominal circumference,body mass,and food intake of mini-pigs in the model group increased at 16 and 24 weeks(P<0.01),there was significant thickening of the inner membrane of aorta,destruction of endothelial cells,lipid deposition,edema of smooth muscle cells,and significant swelling of mitochondria,serum TC,LDL-C contents and the contents of ROS,IL-6,IL-10,TNF-α,hs-CRP,VCAM-1,and ICAM-1 increased,while the content of HDL-C decreased(P<0.01);the expressions of NOX5,p-ERK1/2,VCAM-1,and PCNA proteins in aortic tissue increased(P<0.01).Compared with the model group,Jianpi Qutan Huayu Prescription low-and high-dosage groups showed a decrease in abdominal circumference,body mass,and food intake at 16 and 24 weeks(P<0.05,P<0.01),the plaque area and lipid deposition were reduced,and the damage to endothelial cells was alleviated,serum TC,LDL-C contents and the contents of ROS,IL-6,IL-10,TNF-α,hs-CRP,ICAM-1,and VCAM-1 decreased,and the content of HDL-C increased(P<0.01,P<0.05);the expressiond of NOX5,p-ERK1/2,VCAM-1,and PCNA proteins in aortic tissue decreased(P<0.01,P<0.05).Conclusion Jianpi Qutan Huayu Prescription can effectively alleviate AS in mini-pigs,and its mechanism may be related to inhibiting the activation of the NOX5-ERK1/2 signaling pathway and alleviating oxidative stress-induced inflammatory response.

Objective:To explore the application value of enhanced recovery after surgery (ERAS) in colorectal cancer patients.Methods:From January 2017 to December 2018, 60 patients with colorectal cancer who admitted to the Second People′s Hospital of Lianyungang were selected and divided into ERAS group and control group according to the random digital table method, with 30 patients in each group.The inflammation, nutritional indicators, immune indicators and clinical manifestations before and after surgery in the two groups were compared.Results:At 1 d and 3 d after surgery, the C-reactive protein (CRP) levels in the ERAS group were (70.2±10.3)mg/L, (82.5±8.2)mg/L, respectively, which were lower than those in the control group [(81.5±9.9)mg/L, (110.2±12.9)mg/L] ( t=4.324, 9.911, all P<0.05). On the third day after operation, the levels of albumin and prealbumin in the ERAS group were (31.6±4.8)g/L, (196.8±40.6)g/L, respectively, which were higher than those in the control group [(28.0±5.8)g/L, (172.1±38.8)g/L]( t=2.621, 2.409, all P<0.05). The immune parameters(IgA, IgM, IgG, CD 4+, CD 4+ /CD 8+) in the ERAS group were higher than those in the control group( t=2.132, 2.223, 6.063, 4.253, 2.828, all P<0.05). The number of cases with thirsty and hunger on the day of surgery in the ERAS group was 3 cases and 7 cases, respectively, which were less than 21 cases and 25 cases of the control group(χ 2=22.500, 21.696, all P<0.05). The first exhaust time, defecation time and hospital stay time in the ERAS group were (36.2±12.1)h, (63.4±13.4)h and (9.5±3.2)d, respectively, which were shorter than those in the control group [(54.7±13.8)h, (96.5±18.8)h and (12.1±4.0)d] ( t=5.513, 7.845, 2.761, all P<0.05). The incidence of complications between the two groups had no statistically significant difference ( P>0.05). Conclusion:ERAS can significantly reduce the physical and psychological traumatic stress of patients with colorectal cancer, achieve rapid recovery, improve the treatment effect, shorten the length of hospital stay, reduce social and family burden, and provide a basis for the choice of clinical treatment program.

Objective:To explore the effect of nurse-led outpatient myopia education model in the prevention and control of myopia in children and adolescents.Methods:From July to September 2021, convenience sampling was used to select children who were treated in the Ophthalmology Clinic of Beijing Tongren Hospital and their parents as the research subject. The subjects were divided into the control group and the experimental group according to the date of visit, with 272 children and 272 parents in each group. The subjects in the experimental group were managed by the nurse-led outpatient myopia education model, and the control group received the routine medical treatment model. The myopia knowledge, eye-use habit knowledge, compliance of the parents of the two groups, and eye-use behavior scores of the two groups of children were compared before and after the intervention. In each group, 128 children who were matched for gender and age were selected, and the right eye was used as the research eye to observe the baseline, changes of diopter and axial after half a year.Results:After six months of intervention, the parents' myopia knowledge, eye-use habit knowledge, compliance scores of prevention and control methods, and children's eye-use behavior scores in the experimental group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . The spherical equivalent increase was -0.13 (-0.34, 0.13) D, and the axial growth was 0.16 (0.09, 0.24) mm in the experimental group, respectively -0.25 (-0.50, -0.25) D and 0.23 (0.18, 0.26) mm in the control group, and the differences between groups were statistically significant ( P<0.05) . Conclusions:The nurse-led outpatient myopia education model applied to the prevention and control of myopia in children and adolescents can effectively improve the cognition of myopia prevention and control of parents, the eye-use behavior of children and adolescents, and has a good effect on delaying the progression of myopia.

Objective:To investigate the knowledge level, compliance, attitude and demand of parents of myopic children regarding prevention and control of myopia.Methods:This study was a cross-sectional study. Using the convenient sampling method, a total of 642 children and their parents who visited the ophthalmology clinic of Beijing Tongren Hospital, Capital Medical University from June to September 2021 were selected as the research objects. They were investigated with Self-made Questionnaire on Cognitive Behavior and Demand for Myopia Prevention and Control. A total of 642 questionnaires were sent out in this study, and 638 were effectively received with effective recovery of 99.38% (638/642) .Results:The scores of knowledge, behavior and attitude of 638 parents in the cognitive behavior questionnaire for myopia prevention and control were 13 (11, 15) , 7 (6, 8) , 8 (8, 9) , respectively. 78.68% (502/638) of parents of myopic children thought that they were in great need of myopia prevention and control knowledge. 52.66% (336/638) of parents of myopic children preferred to obtain knowledge about prevention and control of myopia through face-to-face explanation by medical personnel.Conclusions:Parents of myopia children have poor knowledge of myopia prevention and control, and their compliance with prevention and control is at a moderate level. Most parents have a positive attitude towards myopia prevention and control, hoping to receive a reasonable and efficient new model of myopia prevention and control health education to improve their knowledge level, and to cooperate with medical institutions, schools, and the government to take corresponding myopia prevention and control intervention measures to reduce the incidence of high myopia and improve the visual health of myopia children.
