ABSTRACT

OBJECTIVE: The aim of this study was to compare the efficacy and safety of ultrasonic bone curette (UBC) and conventional surgical instruments in thoracic laminectomy decompression (TLD) for the treatment of thoracic spinal stenosis (TSS) by meta-analysis. MATERIALS AND METHODS: Two authors independently searched Medline via PubMed, Embase, Cochrane Library, Web of Science, Wanfang Database, and China National Knowledge Infrastructure for the period from the establishment of the database until January 2023 to identify the studies on the safety and efficacy of UBC vs. conventional instruments for TSS. Data extraction and quality assessment were performed by two researchers independently. We used RevMan 5.4 software (Review Manager Web, The Cochrane Collaboration, Copenhagen, Denmark) to analyze the data. RESULTS: Eight retrospective studies were included in the present work. This meta-analysis revealed that no significant differences in the preoperative JOA scores, the JOA scores at the last follow-up, the improvement rate of JOA scores, and the incidence of cerebrospinal fluid leakage/dura injury were detected between the two groups (p>0.05). However, there were significant differences in the operative time and intraoperative blood loss during single-level TLD [operative time: MD=-1.47, 95% CI (-1.86, -1.09), p<0.001; intraoperative blood loss: MD=-46.62, 95% CI (-53.83, -39.40), p<0.001], total operative time [MD=-56.88, 95% CI (-69.66, -44.10), p<0.001], total intraoperative blood loss [MD=-143.52, 95% CI (-212.49, -74.54), p<0.001], the incidence of neurological deterioration/nerve root injury [RR= 0.29, 95% CI (0.09, 0.91), p=0.03] between the groups. CONCLUSIONS: The application of UBC in TLD to treat TSS is safe and effective. UBC can significantly shorten operation time and reduce intraoperative blood loss compared to traditional surgical instruments. Moreover, it has the advantage of reducing perioperative nerve injury.

ABSTRACT

OBJECTIVE: The aim of this study was to evaluate and aggregate the evidence from the published studies to determine the effectiveness of intradiscal steroid injection (ISI) in patients with symptomatic Modic type I change (MCI). MATERIALS AND METHODS: A systematic literature search was independently performed by two authors. The electronic database, including PubMed, Embase, the Cochrane Library, and Web of Science, were searched with the given search terms but without language restriction. The studies that met the inclusion criteria were included. The relevant data were extracted, and two authors independently assessed the quality of the included studies. We performed the present study using the STATA software package. RESULTS: The present work included seven studies with 434 patients with chronic low back pain (CLBP). The risk of bias in the included randomized controlled trials (RCTs) was rated from low to unclear, and all the included observational studies were rated as high quality. The result of the meta-analysis revealed that there were significant differences in pain intensity [standardized mean difference (SMD): 3.09, 95% confidence interval (CI): 1.60-4.58; p<0.01] and self-assessed improvement/satisfaction [odds ratio (OR): 11.41, 95% CI: 3.39-38.41; p=0.05] after ISI compared to before treatment. However, no significant differences in the proportion of patients with full or part-time employment (OR: 1.03, 95% CI: 0.55-1.91; p>0.05), receiving additional care for CLBP (OR: 0.78, 95% CI: 0.36-1.71; p>0.05), and serious adverse events (OR: 1.09, 95% CI: 0.58 to 2.05; p>0.05) were detected between the groups. CONCLUSIONS: Among CLBP patients with MCI, the use of ISI was significantly associated with a reduction in pain intensity in the short term.

ABSTRACT

OBJECTIVE: A 28-d trial was conducted to evaluate the effect of diets with different energy and lipase levels on performance, nutrient digestibility, serum profiles, gut health, and carcass quality in broilers. METHODS: A total of 720 one-day-old male Ross 308 broilers (45.4±0.5 g) were randomly assigned to one of the following four treatments: i) RET, reduced energy treatment (metabolizable energy = 2,950 and 3,100 kcal/kg for starter and finisher diet), ii) BDT, basal diet treatment (metabolizable energy = 3,050 and 3,200 kcal/kg for starter and finisher diet, iii) RET015, RET+0.15 g/kg lipase, and iv) RET03, RET+0.3 g/kg lipase. There were 10 replications (cages) per treatment with 18 birds per cage. RESULTS: During d 1 to 14, broilers fed BDT, RET015, and RET03 diets had higher (p<0.05) body weight gain than those fed RET diet. During d 1 to 14, 15 to 28 and the overall experiment, feed conversion ratio in RET03 treatment was lower (p<0.05) compared with RET treatment. On d 14, the apparent total tract digestibility (ATTD) of dry matter (DM), ether extract (EE), and gross energy in RET03 treatment was higher (p<0.05) than those in RET treatment, while the ATTD of N was increased (p<0.05) by RET03 treatment. On d 28, broilers fed RET03 diet had higher (p<0.05) ATTD of DM than those fed RET and RET015 diets, while the ATTD of EE in BDT and RET03 treatments was increased (p<0.05) compared with RET and RET015 treatments. Broilers fed RET03 diet had higher villus height (VH) and VH:crypt depth (CD) ratio than those fed RET and BDT diets. The activity of pancreatic lipase in BDT and RET03 treatments was higher (p<0.05) than that in RET treatment. CONCLUSION: Taken together, lipase supplementation (3,000 U/kg feed) increased growth performance, nutrient digestibility, VH, VH:CD ratio and lipase activity, but decreased triglyceride, low-density lipoprotein cholesterol and the abdominal fat percentage in broilers fed reduced energy diet.

ABSTRACT

Bumetanide is a selective inhibitor of the Na+-K+-Cl--co-transporter 1(NKCC1). We studied whether bumetanide could affect axonal growth and behavioral outcome in stroke rats. Adult male Wistar rats were randomly assigned to four groups: sham-operated rats treated with vehicle or bumetanide, and ischemic rats treated with vehicle or bumetanide. Endothelin-1 was used to induce focal cerebral ischemia. Bumetanide administration (i.c.v.) started on postoperative day 7 and continued for 3 weeks. Biotinylated dextran amine (BDA) was injected into the right imotor cortex on postoperative day 14 to trace corticospinal tract (CST) fibers sprouting into the denervated cervical spinal cord. Nogo-A, NKCC1, KCC2 and BDNF in the perilesional cortex and BDA, PSD-95 and vGlut1 in the denervated spinal cord were measured by immunohistochemistry and/or Western blot. Behavioral outcome of rats was assessed by the beam walking and cylinder tests. The total length of CST fibers sprouting into the denervated cervical spinal cord significantly increased after stroke and bumetanide further increased this sprouting. Bumetanide treatment also decreased the expressions of NKCC1 and Nogo-A, increased the expressions of KCC2 and BDNF in the perilesional cortex and enhanced the synaptic plasticity in the denervated cervical spinal cord after cerebral ischemia. The behavioral performance of ischemic rats was significantly improved by bumetanide. In conclusion, bumetanide promoted post-stroke axonal sprouting together accompanied by an improved behavioral outcome possibly through restoring and maintaining neuronal chloride homeostasis and creating a recovery-promoting microenvironment by overcoming the axonal growth inhibition encountered after cerebral ischemia in rats.

ABSTRACT

This study aims to determine the effects of exercise training on carbohydrate and lipid catabolism in the swimming muscles of Nile tilapia (Oreochromis niloticus) by measuring the levels of related enzymes, lipids and free fatty acids. We designed one control group and two training groups of fish that were exercised at different training intensities [0, 1 and 1.5 body lengths per second (bl/s)]. The fish in the experimental groups were trained for 12 h/day for 4 weeks. Compared with the control group, the 1 and 1.5 bl/s groups showed significantly increased hexokinase and pyruvate kinase activities in red muscle (p < 0.05). In white muscle, pyruvate kinase activity was significantly higher in the 1.5 bl/s group than in the control group (p < 0.05), and hexokinase activity did not significantly differ between the groups. The activities of hormone-sensitive lipase and carnitine palmitoyltransferase I in both muscle types were significantly lower in the training groups than in the control group (p < 0.05). The plasma-free fatty acid level decreased (p < 0.05), while the lipid percentages increased in red muscle (p < 0.05) after exercise training. These findings clearly indicated that with exercise training, glycolysis increased and lipid oxidation decreased in the swimming muscle of tilapia.

ABSTRACT

Oncostatin M (OSM) is a multifunctional cellular regulator acting on a wide variety of cells, which has potential roles in the regulation of gene activation, cell survival, proliferation and differentiation. Previous studies have shown that OSM can induce morphological and/or functional differentiation and maturation of many tumor cells. However, the action of OSM on the induction of differentiation of human hepatocellular carcinoma (HCC) has not been reported. Here, we investigated the effects of different concentrations of OSM on human HCC cell line SMMC-7721 growth, proliferation, cell cycling, apoptosis and differentiation in vitro. Cell growth was determined via MTT assay, proliferation by cell cycle analysis, apoptosis by flow cytometry, morphology by transmission electronic microscopy, and cell function by detection of biochemical markers. Our results demonstrated that OSM strongly inhibited the growth of SMMC-7721 cells in a dose-dependent manner, associated with decreased clonogenicity. Cell cycle analysis revealed a decreased proportion of cells in S phase, with arrest at G0/G1. The apotosis rate was increased after OSM treatment compared to the control. These changes were associated with striking changes in cellular morphology, toward a more mature hepatic phenotype, accompanied by significant reduction of the expression of AFP and specific activity of γ-GT, with remarkable increase in secretion of albumin and ALP activity. Taken together, our findings indicate that OSM could induce the differentiation and reduce cell viability of SMMC-7721 cells, suggesting that differentiation therapy with OSM offers the opportunity for therapeutic intervention in HCC.

ABSTRACT

Type 1 diabetes mellitus (T1DM) is mainly caused by reduction of the endogenous insulin secretion due to autoimmune destruction of pancreatic ß cells, and a promising therapeutic approach for T1DM is pancreas and islet cell replacement. The major obstacle is the limited source of insulin-producing cells. Here, we report an efficient approach to induce human adipose-derived stromal cells (hADSCs) to differentiate into insulin-producing cells, with glucagon-like peptide-1 (GLP-1). hADSCs were successfully isolated from the adipose tissue, with adipogenic and osteogenic differentiation potency. Islet-like cell clusters formed in the culture, which was enhanced with the treatment of GLP-1. Reverse transcription polymerase chain reaction analysis showed the expression of the pancreas-related genes in the differentiated cells, such as pdx-1, ngn3, insulin, glucagon, somatostatin, glucokinase n and glut2. Immunocytochemical analysis showed that the induced cells co-expressed insulin, C-peptide and PDX-1. The GLP-1 receptor was present in the differentiated cells. In addition, flow cytometry analysis and ELISA showed that, in the presence of GLP-1, the percentage of insulin-producing cells was increased from 5.9% to 28.0% and the release of insulin increased from 9.53±0.7 pmol/106 cells to 15.86±1.3 pmol/106 cells. Insulin was released in response to glucose stimulation in a manner comparable to that of adult human islets. These results indicated that hADSCs isolated from adipose tissues can be induced to differentiate into insulin-producing cells, which is further enhanced with the treatment of GLP-1. These findings confirm that the differentiation of hADSCs to insulin-producing cells is indeed possible and indicate that the differentiated insulin-producing cells can be used as a potential source for transplantation into patients with T1DM.
