Objective To compare the short-term efficacy and occurrence of complication of endoscopic laminar fenestration (Endo-LOVE) and percutaneous endoscopic transforaminal decompression (PETD) in patients with degenerative lumbar lateral recess stenosis (LSLRS). Methods A total of 160 patients with LSLRS were enrolled as study objects, and were randomly assigned to control group (treated with PETD) and observation group (treated with Endo-LOVE), with 80 patients in each group. Surgical indicators, occurrence of complications, and therapeutic effects were observed and compared between the two groups. Bone lateral recess angle, soft lateral recess angle, Oswestry Disability Index (ODI) score, pain score, and Japanese Orthopaedic Association (JOA) score were compared before and after surgery. Results The observation group had less intraoperative blood loss, and shorter operative and hospital stays than the control group (P < 0.05). There were no statistically significant differences in the incidence of complications such as lower limb numbness, fever, and postoperative low back pain between the two groups (P>0.05). There were no statistically significant differences in preoperative bone lateral recess angle or soft lateral recess angle between the two groups (P>0.05). At 72 hours postoperatively, both angles increased in both groups compared with preoperative values, and the observation group had larger angles than the control group (P < 0.05). There were no statistically significant differences in preoperative pain score, ODI score, or JOA score between the two groups (P>0.05). At 3 months postoperatively, JOA scores increased and pain scores as well as ODI scores decreased in both groups compared with preoperative values, with the observation group having higher JOA scores and lower pain scores as well as ODI scores than the control group (P < 0.05). The excellent and good rate was 96.25%(77/80) in the observation group, which was higher than 87.50%(70/80) in the control group (P < 0.05). Conclusion Compared with the PETD approach, the Endo-LOVE approach for the treatment of LSLRS offers shorter operative time, less intraoperative blood loss, and better short-term efficacy.

Objective:To analyze the association between healthy lifestyle and mortality among Henan Province 35-74 years old individuals.Methods:Data from the programme of screening and intervention subjects with high-risk cardiovascular disease 99 133 adults were analyzed in a provincial cohort study of 16 counties. Four healthy lifestyle behaviors were assessed based on a questionnaire survey. Information on mortality endpoints was retrieved from the national death surveillance system. Cox proportional hazards regression models were used to estimate the associations between healthy lifestyles, mortality risk and population attributable fraction (PAF).Results:Out of the adult participants in Henan, 50.6% adhered to a healthy lifestyle, and only 0.1% adhered to 4 healthy lifestyle behaviours. During a mean of 4.5 years, 2 685 all-cause death and 1 283 cardiovascular deaths were documented. The decreased risk of mortality among individuals with non-smoking, moderate drinking, adequate exercise and healthy diet were 0.85 (95% CI: 0.77-0.94), 0.75 (95% CI: 0.63-0.89), 0.73 (95% CI: 0.67-0.79) and 0.86 (95% CI: 0.77-0.96), while the adjusted PAF for all-cause deaths were 5.2% (95% CI: 2.5%-7.9%), 24.0% (95% CI: 10.7%-36.4%), 19.4% (95% CI: 13.8%-24.8%) and 12.3% (95% CI: 3.4%-20.9%), respectively. A combined healthy lifestyle can bring more health benefits. Adherence to 4 healthy lifestyle behaviours could avoid 49.1% of all-cause death. Conclusion:Adherence to a healthy lifestyle can reduce the risk of death, and participants with a healthy lifestyle had a lower mortality risk.

Objective:To explore the mechanism of Dahuangfuzi decoction on intestinal motility disorder by observing its effect on serum motilin, Cajal interstitial cells and motilin receptor in rats with severe acute pancreatitis (SAP).Methods:Eighteen clean male Sprague-Dawley rats were randomly divided into the control group, SAP group and Dahuangfuzi group ( n=6 each group). The SAP rat model was prepared by retrogradely injected 4% sodium taurocholate into cholangiopancreatic duct. The rats in the SAP group were given 2 mL normal saline (37℃) enema at 12 and 24 h after operation. The rats in the Dahuangfuzi group was given 2 mL Dahuangfuzi decoction (37℃) enema at 12 and 24 h respectively. For the control group, the pancreas was exposed in the same way and then the abdomen was closed. Forty-eight h after operation, the abdominal aorta blood samples were taken for determination of serum endotoxin and amylase, and for detection of serum motilin by enzyme-linked immunosorbent assay (ELISA); the pathological changes of pancreas and ileum were observed by hematoxylin-eosin (HE) staining. The expression of c-kit and motilin receptor protein in ICC in ileum tissue was detected by immunohistochemistry. Results:Compared with the control group, the levels of serum endotoxin and amylase in the SAP group were significantly higher [(504.98±88.81) pg/mL vs. (17.76±5.01) pg/mL; (532.28±66.53) vs. (69.45±3.61) U/L, P<0.05], while the levels of serum motilin were significantly lower [(195.4±6.7) ng/L vs. (301±8.10) ng/L, P<0.05], and the scores of c-kit and motilin receptor protein were decreased ( P<0.05); compared with the SAP group, the levels of serum endotoxin and amylase in the Dahuangfuzi group were significantly reduced [(189.9±38.23) pg/mL vs. (504.98±88.81) pg/mL; (294.23±25.66) vs. (532.28±66.53) U/L, P<0.05], while the levels of serum motilin were significantly increased [(264.2±8.3) ng/L vs. (195.4±6.7) ng/L, P<0.05], and the scores of c-kit and motilin receptor protein were increased ( P<0.05). Conclusions:Dahuangfuzi decoction can improve the intestinal motility of SAP rats by promoting the secretion of motilin, increasing the activity of ICC cells and the expression of motilin receptor.

Objective:To study the effects of hydrogen molecule on the formation of pelvic and abdominal adhesions in dogs, and to explore its possible mechanism.Methods:The Beagle pelvic and abdominal adhesion model was constructed. 15 Beagle dogs were randomly divided into 3 groups: model control group, hydrogen treatment group and blank control group. The Phillips adhesion score was used to evalute the morphological adhesion degree. The morphology of intestinal, uterus and ovarian tissues was evaluated by hematoxylin-eosin (HE) staining. The inflammation biomarkers and oxygen free radical index were detected before modeling and on the 1st, 4th, 7th and 14th day after modeling. C-reactive protein (CRP), tumor necrosis factors-α (TNF-α) and interleukin(IL)-6 content in serum were detected by enzyme-linked immunosorbent assay (ELISA) kit; hydroxylamine method was used to detect the serum superoxide dismutase (SOD); thiobarbituric acid (TBA) colorimetric method was used to measure malondialdehyde concentration.Results:The Phillips adhesion score of the model control group was significantly higher than that of the blank control group ( P<0.05). The Phillips adhesion score of the hydrogen treatment group was significantly lower than that of the model control group ( P<0.05). In the hydrogen treatment group, the thickening of serous layer on the surface of intestine, uterus and ovary and the degree of inflammatory infiltration were lower than those in the model control group.The inflammatory indexes (leukocyte count, CRP, IL-6, TNF-α) and malondialdehyde level in the model control group were higher than those in the blank control group on the first day after modeling, and the superoxide dismutase (SOD) level was lower than that in the blank control group (all P<0.05); the inflammatory indexes and malondialdehyde level in the hy-drogen treatment group were lower than those in the model control group on the first day after modeling ( P<0.05), and the SOD level was higher than that in the model control group ( P<0.05). Conclusions:Hydrogen molecule can effectively inhibit the formation of pelvic adhesion in Beagle dogs, and its possible mechanism is to neutralize oxygen free radicals and reduce inflammatory reaction.

Objective: To investigate the effect and mechanism of atorvastatin (ATV) on the inflammatory response of human renal tubular epithelial cells (HK-2 cells) induced by calcium oxalate crystals. Methods: HK-2 cells were divided into control group (normal medium), ATV group (after 3 h pretreatment with 40 μmol/L ATV, replaced with normal medium), calcium oxalate crystal stimulation group (4 mmol/L calcium oxalate crystal) and ATV treatment group (after 3 h pretreatment with 40 μmol/L ATV, replaced with 4 mmol/L calcium oxalate crystals). After 12 h, the cells were collected, and the expression levels of NLRP3 and Cleaved caspase-1 were detected by immunohistochemical staining and Western blotting. The expression level of NF-κB was detected by immunofluorescence and Western blotting. The cell culture supernatant was collected to detecte the concentrations of interleukin-1β (IL-1β) and interleukin-18 (IL-18) by enzyme linked immunosorbent assay (ELISA). Results: Western blot analysis showed that the relative expression of NLRP3 (0.125±0.013 vs. 0.135±0.007) and Cleaved caspase-1 (0.090±0.014 vs. 0.095±0.006) was decreased in the ATV group compared with the control group, but the difference was not statistically significant (P>0.05). The relative expression of NLRP3 (0.315±0.021 vs. 0.135±0.007, P<0.001) and Cleaved caspase-1 (0.235±0.008 vs. 0.095±0.006, P<0.001) was significantly increased in the calcium oxalate crystal stimulation group compared with the control group. While the relative expression of NLRP3 (0.245±0.007 vs. 0.315±0.021, P<0.05) and Cleaved caspase-1 (0.170±0.017 vs. 0.235±0.008, P<0.05) in the ATV treatment group was significantly lower than that in the calcium oxalate crystal stimulation group. The results of immunohistochemical staining showed that the expression trends of NLRP3 and Cleaved caspase-1 in each group were consistent with those obtained by Western blotting. The ELISA results showed that the concentration of inflammatory factors IL-1β [(162.00±21.21)pg/ml vs. (183.50±7.78) pg/ml, P>0.05] and IL-18 [(176.50±24.12)pg/ml vs.(182.50±20.51)pg/ml, P>0.05] in the ATV group was lower than that in the control group, but the difference were not statistically significant (P>0.05). The concentrations of IL-1β[(850.50±48.79)pg/ml vs. (183.50±7.78)pg/ml, P<0.001] and IL-18 [(526.00±39.61)pg/ml vs. (182.50±20.51)pg/ml, P<0.001] were significantly increased in the cell culture medium of the calcium oxalate crystal stimulation group compared with the control group, while the concentrations of IL-1β [(452.50±36.06)pg/ml vs. (850.50±48.79) pg/ml, P<0.01] and IL-18 [(403.50±23.33)pg/ml vs. (526.00±39.61)pg/ml, P<0.05] was significantly reduced in the cell culture medium of the ATV treatment group compared with the calcium oxalate crystal stimulation group. Western blot analysis showed that the relative expression of NF-κB (0.105±0.021 vs. 0.100±0.014) in the ATV group was decreased compared with the control group, but the difference was not statistically significant (P>0.05). The relative expression of NF-κB (0.295±0.035 vs. 0.100±0.014, P<0.001) in the calcium oxalate crystal stimulation group was significantly increased compared with the control group. While the relative expression of NF-κB (0.160±0.012 vs. 0.295±0.035, P<0.05) in the ATV treatment group was significantly lower than that in the calcium oxalate crystal stimulation group. The expression of NF-κB by immunofluorescence staining was consistent with the results of Western blotting. Conclusions Calcium oxalate crystals can induce the inflammatory response of HK-2 cells, while ATV can exert anti-inflammatory effects by inhibiting the activation of NLRP3 inflammasome and decreasing the secretion of inflammatory factors IL-1β, IL-18 and the expression of NF-κB.

[Abstract] Objective: To explore the mRNA molecular targets for diagnosis of hepatic carcionoma and to investigate their functional roles in proliferation and cell cycle of hepatic cancer cells. Methods: Based on the statistical analysis of miRNA expression data from 377 hepatic carcionoma samples and 37 adjacent non-cancerous samples in TCGAdatabase, a group of 33 differentially expressed miRNAs were identified.A further screen of these differentially expressed miRNAs was performed using the receiver operating characteristic curve (ROC curve) and Kaplan-Meier survival analysis; and with referring to the current publications, miR-451 was screened as the study subject. HepG2 cells were transfected with pLVX-shRNA2-miR-451 to over-express miR-451. The effect of miR-451 over-expression on the proliferation of HepG2 cell was determined by CCK-8 assay; while the effect on cell cycles was detected by flow cytometry. Results: The expression of miR-451 in the adjacent non-cancerous tissues was significantly lower than that in cancer tissues ([473.40±390.24] vs [1 990.47±2 118.04], P<0.05). MiR-451 could be used as an early diagnostic biomarker of hepatic carcionoma, with a high ROC value of 0.91 (sensitivity 0.89, specificity 0.87). The results of in vitro experiments showed that the proliferation of HepG2 cells was significantly decreased after miR-451 over-expression (48 h: [0.69±0.04] vs [1.08±0.05]; 72 h: [0.76±0.07] vs [1.52± 0.02]; all P<0.01), and a large number of cells were blocked in S phase(P<0.05). Conclusion: miR-451 has the potential to be used as a biomarker for hepatic carcionoma diagnosis and prognosis; moreover, it also exhibits the inhibitory effect on proliferation of hepatic cancer cells.
