Objective:To study the effect of ulinastatin combined with early enteral nutrition on severe acute pancreatitis and its effect on nuclear factor-κB(NF-κB) and Toll-like receptor 4 (TLR4).Methods:Ninety severe acute pancreatitis patients who were treated in Central Hospital of Lijin County from January 2016 to January 2020 were selected and were divided into U+EEN group (ulinastatin combined with early enteral nutrition therapy) and EEN group (early enteral nutrition therapy) by random number table method, with 45 patients in each group. Curative effect, complications, nutritional indicators, immunoglobulins and inflammatory factors were detected and compared with analysis of variance. Western blot was used to detect the expression of NF-κB and TLR4 in pancreatic tissue in two groups.Results:The hospitalization time, ICU admission time, intestinal ventilation time, hospitalization costs and organ failure rate, pancreatic cysts, diabetes, chronic pancreatitis, incidence of sepsis in U + EEN group were lower than those in EEN group: (2.1 ± 0.4) months vs. (2.4 ± 0.6) months, (16.9 ± 2.1) d vs. (21.7 ± 2.8) d, (23.7 ± 3.8) d vs. (27.4 ± 4.1) d, (11.4 ± 1.5) thousand Yuan vs. (14.1 ± 2.1) thousand Yuan and 8.9%(4/45) vs. 20.0%(9/45), 13.3%(6/45) vs. 28.9%(13/45), 11.1%(5/45) vs. 24.4%(11/45), 8.9%(4/45) vs. 26.7%(12/45), 6.7%(3/45) vs. 22.2%(10/45), and the differences were statistically significant ( P<0.05). The levels of prealbumin (PA), albumin (ALB) and total protein (TP) after treatment in U + EEN group were higher than those in EEN group: (107.4 ± 6.5) mg/L vs. (102.8 ± 4.7) mg/L, (46.1 ± 3.5) g/L vs. (43.4 ± 2.8) g/L, (55.9 ± 3.4) g/L vs. (53.7 ± 3.1) g/L, and the differences were statistically significant ( P<0.05). The levels of IgG, IgA, IgM after treatment in U+EEN group were higher than those in EEN group: (10.5 ± 1.6) g/L vs. (9.5 ± 1.3) g/L, (8.9 ± 1.4) mg/L vs. (8.3 ± 1.2) mg/L, (60.5 ± 3.6) mg/L vs. (55.9 ± 3.4) mg/L, the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-8 in U+EEN group were lower than those in EEN group: (25.1 ± 2.9) mg/L vs. (30.6 ± 4.1) mg/L, (20.1 ± 1.9) mg/L vs. (24.6 ± 1.5) mg/L, (17.8 ± 1.9) mg/L vs. (20.1 ± 2.3) mg/L, and the differences were statistically significant ( P<0.05). The expressions of NF-κB and TLR4 protein in pancreatic tissue of patients in U + EEN group were significantly lower than those in EEN group (0.3 ± 0.2 vs. 0.5 ± 0.2, 0.2 ± 0.1 vs. 0.5 ± 0.1, P<0.05). Conclusions:Ulinastatin combined with early enteral nutrition can significantly improve the nutritional status and immune function and improve the prognosis of patients with severe acute pancreatitis, which may be related to ulinastatin′s reduction effect of NF-κB and TLR4′s expressions.

Objective To evaluate the clinical effect of vertebra pedical nail strengthened by bone cement.Methods 48 cases with vertebral illness were divided into two groups,each group of 24 cases.One group goes ahead of the restvertebra pedical nail dishpour into viscous polymethyl methacrylate(PMMA),another group fixed by regular vertebra pedical nail.VAS score,spinal stability and JOA score were adopted to evaluate curative effect synthetically.Results After 1 month,6 months,12 months,the VAS scores in the treatment group were(3.12 ± 1.65),(3.08 ±1.10),(3.09 ± 1.25),and the VAS scores in the control group were(4.31 ±2.13),(4.22 ± 1.48),(4.12 ±1.34),the VAS scores had statistically significant differences between the two groups postoperative 1 month,6months,12 months(t =2.15,2.08,1.97,all P＜0.05);after 1 month,6 months,12 months JOA scores in the treatment group were(26.76 ±4.36),(26.78 ±2.10),(26.96 ± 1.89),and JOA scores in the control group were (24.13 ± 5.28),(24.32 ± 1.68),(24.32 ± 1.99),the JOA score differences had statistically significances between the two groups(x2 =5.031,P ＜0.05);the excellent rates of the treatment group was 90.13％,which was higher than 85.01％ of the control group(t =3.54,3.39,3.56,all P ＜ 0.05).Conclusion Patients receiving vertebra pedical nail strengthened by bone cement was better than regular vertebra pedical nail skill.

Objective To observe the influence of low protein diet with α-keto acid on kidney sclerosis and renin-angiotensin system in renal ablation rats. Methods Chronic renal failure rat model was established by renal ablation in 30 male SD rats,then the animals were randomly assigned to the following diet groups:normal protein group (NPD:18%casein protein),low protein group (LPD:6%casein protein) and supplemented low protein group (LK:5%casein protein+1%α-keto acids).Ten male SD sham-operated rats received 18%casein protein as control.All the rats were killed at the end of the 12th week.Pathologic changes were assessed by PAS staining.Ang II in homogenate and plasma were measured by radioimmunoassay and ELISA respectively.Immunohistochemistry and Western blotting were used to detect the protein expression of TGF-β1,renin and AT1R.Real-time PCR was used to detect the gene expression of renin and ATla,the main subtype of AT1 receptor. Results Body weight,total protein and serum albumin had not significant difference among the four groups(all P>0.05).Serum creatinine and proteinuria of nephrectomized rats were significantly higher compared to the control group (all P<0.05).Proteinuria of the LK group was lower than that of NPD and LPD groups (all P<0.05).Pathological results indicated fibrosis indices were significantly improved after LPD and LK intervention.Expressions of renin,Ang II and AT1R in LK group were significantly lower than those in NPD group (all P<0.05). Conclusions Low protein diet with α-keto acids supplement therapy exhibits renal protective effects of reducing urine protein excretion and improving renal fibrosis,which might be related to the attenuation of local renin-angiotensin system in activity nephrectomized rats.

AIM:To observe the situation of rat retinal tissue DNA damage at early diabetic period, discuss the role of the blood glucose fluctuations, and provide a new method for studying the pathogenesis of diabetic retinopathy ( DR) .
METHODS: SD rats were randomly divided into four groups:normal control group (NC), normal fluctuation group ( NF ) , diabetes group ( DM ) and diabetes fluctuation group ( DF ) . Diabetic models were established through intraperitoneal injection of STZ. A certain amount of glucose was injected in the rats of group NF and DF in an intraperitoneal mode three times a day after the model was established, thereby causing blood glucose fluctuations. Rats were killed and the retinal tissues were taken in the 8th week. Single cell gel electrophoresis ( SCGE ) technique was adopted for detecting DNA injury extent in the retina tissue.
RESULTS:Groups NF and DF showed significant and regular fluctuations. The curve of blood glucose fluctuations was relatively stable. All values of MBG, SDBG, LAGE and M were significantly increased compared with group NC. Group DF was increased more significantly. It was statistically significant (P<0. 01). SCGE showed that there were DNA damages in different levels in the cells of group NF, DM and DF. Indicators of cells such as TL, TDNA %, TM, OTM were higher than that in group NC. It was statistically significant ( P<0-01). The comparison difference between two groups was also significant (P<0. 01).
CONCLUSION: Rat retinal tissues have DNA injury during early diabetic period. DNA injury is gradually aggravated with blood glucose fluctuation. It indicates that high blood glucose and blood glucose fluctuation are involved in the mechanism of cell DNA injury, and they may be one of DR early event, have played a certain role in the incidence of DR.

Objective To evaluate the application value of DNA ploidy detection using flow cytometry method(FCM)in malignant tumor identifi?cation,so as to provide the theoretical basis for the clinical diagnosis of malignant tumors. Methods Two researchers finished the literature screen?ing independently,and all the literatures were given the secondary screening according to the inclusion and exclusion criteria. The included literature data was analyzed by Meta?DiSc 1.4,including heterogeneity test,sensitivity,specificity,diagnostic odds ratio(DOR)and summary receiver operat?ing characteristic(SROC)etc. Results Totally 12 literatures were included in the study finally,including a total of 1 340 subjects consisting of 516 cases with malignant tumor and 824 cases with benign tumor. Heterogeneity inspection results showed that the Spearman correlation coefficient of sensitivity logarithm and(1-specificity)logarithm was-0.343 and there was no threshold effect(P=0.275). DOR curves was Cochran?Q=26.49 (P=0.005 5),indicating the heterogeneity was caused by non threshold effects. Combined statistical quantity was calculated with a random effects model and the results were as followings:the sensitivity was 0.72(95%CI:0.68?0.76,I2=50.1%)and the specificity 0.84(95%CI:0.81?0.86,I2=65.5%). SROC curve drawing,DNA ploidy detection of benign and malignant tumors showed AUC=0.845 3 and Q*=0.776 8. Conclusion FCM DNA heteroploid has a high accuracy for diagnosis of malignant tumor,which can be an important supporting means for the discrimination between benign and malignant tumor.
