Objective To investigate the effects of heme oxygenase-1/carbon monoxide (HO-1/CO) pathway on mitochondrial fusion in rat alveolar epithelial type Ⅱ cells (AECⅡ) stimulated by lipopolysaccharide (LPS). Methods Once the cultured in vitro rat AECⅡcells line RLE-6TN reached confluency of 85%, they were subcultured and randomly divided into seven groups (n = 5 each). RLE-6TN cells were routinely cultured in control group. The cells in LPS group was stimulated with 10 mg/L LPS to reproduce the model of endotoxin challenge in AECⅡ cells. The cells in carbon monoxide-releasing molecule-2 (CORM-2, in vitro CO release agent) + LPS group (CL group) and Hemin (HO-1 inducer) + LPS group (HL group) were pretreated with 100 μmol/L CORM-2 or 20 μmol/L Hemin for 1 hour, respectively, followed by 10 mg/L LPS stimulation. The cells in zinc protoporphyrin-Ⅸ (ZnPP-Ⅸ, HO-1 inhibitor) + LPS group (ZL group) was pretreated with 10 μmol/L ZnPP-Ⅸ for 0.5 hour followed by 10 mg/L LPS stimulation. The cells in CORM-2 + ZnPP-Ⅸ + LPS group (CZL group) and Hemin + ZnPP-Ⅸ + LPS group (HZL group) were pretreated with 100 μmol/L CORM-2 or 20 μmol/L Hemin respectively for 1 hour, and other treatments were similar to those previously described in ZL group. At 24 hours after LPS stimulation, interleukin-6 (IL-6)and tumor necrosis factor-α (TNF-α) in the supernatant were determined by enzyme linked immunosorbent assay (ELISA), the protein expressions of HO-1, mitochondrial fusion related proteins 1 and 2 (Mfn1, Mfn2) and optic atrophy 1 (OPA1) were determined by Western Blot. Results Compared with control group, IL-6 and TNF-α contents in the supernatant were increased, HO-1 protein expression was up-regulated, Mfn1, Mfn2 and OPA1 protein expressions were down-regulated in all treatment groups. Compared with LPS group, IL-6 and TNF-α contents were significantly decreased after CORM-2 or Hemin pretreatment [IL-6 (ng/L): 48.6±3.7, 48.4±3.1 vs. 58.7±2.5; TNF-α (ng/L):40.7±5.3, 39.4±4.3 vs. 51.8±5.1], the protein expressions of HO-1, Mfn1, Mfn2 and OPA1 were significantly up-regulated (HO-1 protein: 0.873±0.051, 0.839±0.061 vs. 0.671±0.044; Mfn1 protein: 0.673±0.037, 0.654±0.025 vs. 0.568±0.021; Mfn2 protein: 0.676±0.044, 0.683±0.035 vs. 0.571±0.043; OPA1 protein: 0.648±0.031, 0.632±0.031 vs. 0.554±0.032; all P < 0.05); while opposite effects were found after ZnPP-Ⅸ preincubation, and there were significant differences in IL-6 and TNF-α contents and protein expressions of HO-1, Mfn1, Mfn2 and OPA1 as compared with those of LPS group [IL-6 (ng/L): 69.8±5.1 vs. 58.7±2.5, TNF-α (ng/L): 61.9±3.3 vs. 51.8±5.1, HO-1 protein: 0.545±0.023 vs. 0.671±0.044, Mfn1 protein: 0.406±0.051 vs. 0.568±0.021, Mfn2 protein:0.393±0.051 vs. 0.571±0.043, OPA1 protein: 0.372±0.050 vs. 0.554±0.032; all P < 0.05]. There were no significant differences in the parameters mentioned above between HL group and CL group, as well as among LPS, CZL and HZL groups. Conclusion HO-1/CO pathway promotes mitochondrial fusion and alleviates inflammatory response in LPS-induced rat AECⅡ cells.

OBJECTIVETo explore the value of spinal canal and dural sac dimensions for the treatment of lumbar disc herniation in MRI.

METHODSThe clinical data of 144 patients with single-level lumbar disc herniation underwent nonsurgical or surgical treatment from January 2010 to December 2012 were retrospectively analyzed. There were 91 patients in the nonsurgical group, including 55 males and 36 females, ranging in age from 20 to 68 years old with an average of (43.37±12.48) years; and there were 53 patients in the surgical group, including 28 males and 25 females, ranging in age from 20 to 64 years old with an average of (42.98±12.95) years. JOA scores (29 scores) were used to evaluate clinical manifestation (including subjective symptoms, objective findings, limitation of daily activities and bladder function) and outcomes. The parameters related to spinal canal and dural sac dimensions (including spinal canal midsagittal diameter and available diameter, lateral recess width, spinal canal and dural sac cross-sectional area) in the initial axial T2-weighted MRI were measured, and odds ratio of available diameter to midsagittal diameter, odds ratio of lateral recess width to midsagittal diameter and area ratio of dural sac to spinal canal were calculated. Then, the differences of all parameters between two groups, and the correlations with initial JOA scores were analyzed.

RESULTS(1) All patients were followed up from 1 to 3 years with an average of 2.1 years. JOA scores before treatment were 16.27±2.96 in nonsurgical group and 12.64±3.30 in surgical group, there was statistically significant difference (t=6.319, P<0.01). At final follow-up time, there was no statistically significant difference in JOA scores (25.41±2.22 vs 25.76±2.29), improvement rate [(72.95±12.54)% vs (76.80±9.45)%], and the excellent and good rate (84.91% vs 78.02%) between two groups (P>0.05). But, the relapse rate of nonsurgical group was higher than surgical group (14.29% vs 5.67%). (2) Spinal canal midsagittal diameter and available diameter, lateral recess width, spinal canal and dural sac area, the ratio of available diameter to midsagittal diameter, and the ratio of lateral recess width to midsagittal diameter in surgical group were smaller than that of nonsurgical group, but the area ratio of dural sac to spinal canal was larger, and there were statistically significant differences between two groups (P<0.01). (3) The initial JOA scores showed significantly positive correlation with spinal canal midsagittal diameter and available diameter, lateral recess width, and canal and dural sac area (P<0.01); also presented positive correlation with the ratio of available diameter to midsagittal diameter and the ratio of lateral recess width to midsagittal diameter (P<0.05); but there was a significantly negative correlation between initial JOA scores and the area ratio of dural sac to spinal canal.

CONCLUSIONBoth nonsurgical and surgical treatment of lumbar disc herniation can obtain good effect, but the recurrence rate of non-surgical treatment is higher. Preoperative MRI measurement parameters of spinal canal and dural sac dimensions has certain value for the treatment selection of lumbar disc herniation, but further refinement and validation is still required.

This study was aimed to compare the efficacy of gastric banding (GB), Roux en-Y gastric bypass (RYGBP) and biliopancreatic diversion (BPD) in the treatment of rats with type 2 diabetes mellitus (T2DM). Ani-mal models of T2DM were induced by streptozotocin (STZ) injection and high-sugar-fat diets. A total of 70 T2DM rats were randomly allocated into the GB group (G group, n = 20), RYGBP group (R group, n = 20), BPD group ( B group , n = 20 ) , and the sham operation group ( S group , n = 10 ) . The fasting blood glucose ( BG ) , triglyceride ( TG ) , total cholesterol ( TC ) and insulin ( INS ) content were determined before and 1 , 2 , 3 , 4 , 8 , 16 weeks after operation. The insulin sensitivity index (ISI) was calculated. The mortality and complications were ob-served in each group. The results showed that the fasting weight of the GB group, RYGBP group and BPD group were (324.4 ± 22.5) g, (338.9 ± 17.5) g, (333.3 ± 28.4) g, respectively. The BG content was (12.44 ± 1.29) mmol/L, (9.70 ± 0.81) mmol/L, (11.93 ± 2.39) mmol/L, respectively. The TC content was (2.32 ± 0.45) mmol/L, (2.22 ± 0.79) mmol/L, (2.13 ± 0.31) mmol/L, respectively. The TG content was (1.38 ± 0.32) mmol/L, (1.16± 0.41) mmol/L, (1.23 ± 0.35) mmol/L, respectively. The ISI were (-6.38 ± 0.29), (-6.67 ± 0.24), (-6.65 ±0.23), respectively. And the INS content of the RYGBP group were (69.43 ± 18.73) mU/L. There were signifi-cant differences between before and after operation on the 16th week ( P < 0 . 05 , P < 0 . 01 ) . The mortality rate was 5% in the GB group, 20% in the RYGBP group, and 35% in the BPD group. It was concluded that the GB, RYGBP and BPD are effective in reducing blood glucose and blood lipids in the treatment of rat with T2DM. The treatment effect is obvious in the improvement of insulin resistance ( IR ) .

The traditional Chinese medicine (Tripterygium wilfordiiHook.f.,TWH) has been clinically used to treat primary and secondary renal diseases and proteinuria for nearly 40 years.However,there is a rare literature about the effect of triptolide (the main active ingredient of TWH) on the expression of oxidative carbonyl protein (OCP) in diabetic nephropathy (DN).This study aimed to provide experimental evidence for triptolide treatment on DN through its effect on the expression of OCP,in order to investigate the effects of triptolide on the expression of OCP in rats with DN.Sixty SD rats were randomly divided into five groups:control group,high-dose triptolide (Th) group,low-dose triptolide (T1) group,DN model group,and positive control (benazepril) group.The DN model was established using streptozotocin.Urinary protein excretion,fasting blood glucose (FBG),superoxide dismutase (SOD) in renal homogenate,malondialdehyde (MDA) in renal homogenate and renal nitrotyrosine by immunohistochemistry,and the expression of OCP by oxyblotimmune blotting were detected.In the DN model group,rat urinary protein excretion and renal MDA were significantly increased,while renal SOD significantly decreased and nitrotyrosine expression was obviously upregulated in the kidney.After triptolide treatment,24-h urinary protein excretion (61.96±19.00 vs.18.32±4.78 mg/day,P＜0.001),renal MDA (8.09±0.79 vs.5.45±0.68 nmol/L,P＜0.001),and nitrotyrosine expression were decreased.Furthermore,renal OCP significantly decreased,while renal SOD (82.50±19.10 vs.124.00±20.52 U/L,P＜0.001) was elevated.This study revealed that triptolide can down-regulate the expression of OCP in the renal cortex of DN rats.
