STUDY DESIGN. Meta-analysis of literature. OBJECTIVE. To evaluate the effect of perioperative nonsteroidal anti-inflammatory drugs (NSAIDs) on the success rate of adult spinal fusion. SUMMARY OF BACKGROUND DATA. NSAIDs are commonly used to treat postsurgical orthopedic pain. Studies on animal models have shown a significant inhibiting effect of NSAIDs on osteogenesis process, on which spinal fusion also depends. Recently, great interest has been shown in the effect of NSAIDs on the success rate of adult spinal fusion. Clinical trials have tested the effect of perioperative NSAIDs in spinal fusion procedures. A cumulative result of these studies would give more credit to the final conclusions. METHODS. A systematic search of electronic databases and references from eligible articles was conducted. Comparative studies reporting on the results of primary spinal fusion including treatment group of NSAIDs perioperatively were regarded eligible. A pooled estimate of effect size was produced using both random and fixed effect model. RESULTS. Five retrospective comparative studies (n = 1403 participants) were included in the present study. The mean age of these patients was more than 40 years and none of them had NSAIDs for longer than 14 days following spinal fusion surgery. High-dose ketorolac showed a statistically significant adverse effect on spinal fusion (P = 0.001, RR = 2.87, 95% CI = 1.53 = - 5.38) with no statistical heterogeneity (I = 3%, P = 0.38), whereas normal-dose NSAIDs (ketorolac, diclofenac sodium, celecoxib, or rofecoxib) did not appear to produce inferior results than the no-NSAIDs group (P = 0.30, RR = 1.39, 95% CI = 0.74 - 2.61) with no statistical heterogeneity (I = 0%, P = 0.50). CONCLUSION. Although randomized controlled trials would be optimal for meta-analyses, the data of this review revealed that short-time (<14 days) exposure to normal-dose NSAIDs (ketorolac, diclofenac sodium, celecoxib, or rofecoxib) were safe after spinal fusion, whereas short-time (<14 days) exposure to high-dose ketorolac increased the risk of nonunion, which meant that the effect of perioperative NSAIDs on spinal fusion might be dose-dependent. Further studies would be needed to find out whether long-time exposure to normal-dose NSAIDs could also increase the risk of nonunion and which type of NSAIDs would like to have a worse effect on spinal fusion. © 2011 Lippincott Williams & Wilkins, Inc.

Background. Robotic colorectal surgery may solve some of the problems inherent to conventional laparoscopic surgery (CLS). We sought to evaluate the advantages of robot-assisted laparoscopic surgery (RALS) using the da Vinci Surgical System over CLS in patients with benign and malignant colorectal diseases. Methods. PubMed and Embase databases were searched for relevant studies published before July 2011. Studies clearly documenting a comparison of RALS with CLS for benign and malignant colorectal diseases were selected. Operative and postoperative measures, resection margins, complications, and related outcomes were evaluated. Weighted mean differences, relative risks, and hazard ratios were calculated using a random-effects model. Results. The meta-analysis included 16 studies comparing RALS and CLS in patients with colorectal diseases and 7 studies in rectal cancer. RALS was associated with lower estimated blood loss in colorectal diseases (P = 0.04) andrectal cancer (P<0.001) and lower rates of intraoperative conversion in colorectal diseases (P = 0.03) and rectal cancer (P<0.001) than CLS. In patients with colorectal diseases, however, operating time (P<0.001) and total hospitalization cost (P = 0.06) were higher for RALS than for CLS. Conclusions. RALS was associated with reduced estimated blood loss and a lower intraoperative conversion rate than CLS, with no differences in complication rates and surrogate markers of successful surgery. Robotic colorectal surgery is a promising tool, especially for patients with rectal cancer. © Society of Surgical Oncology 2012.

Recently, numerous types of human dental tissue-derived mesenchymal stem cells (MSCs) have been isolated and characterized, including dental pulp stem cells, stem cells from exfoliated deciduous teeth, periodontal ligament stem cells, dental follicle progenitor cells, alveolar bone-derived MSCs, stem cells from apical papilla, tooth germ progenitor cells, and gingival MSCs. All these MSC-like cells exhibit self-renewal, multilineage differentiation potential, and immunomodulatory properties. Several studies have demonstrated the potential advantages of dental stem cell-based approaches for regenerative treatments and immunotherapies. This review outlines the properties of various dental MSC-like populations and the progress toward their use in regenerative therapy. Several dental stem cell banks worldwide are also introduced, with a view toward future clinical application. Stem Cells 2015;33:627-638 © 2014 AlphaMed Press.

Subarachnoid hemorrhage (SAH) is a frequent occurrence in cerebrovascular accidents, and inflammation occurs in the subarachnoid space after SAH. Arachnoid cells have the capability to present antigens and active T-lymphocytes after stimulation by cerebrospinal fluid (CSF). However, the effect of CSF on T-lymphocytes and arachnoid cell adhesion was not clearly understood. In this study, we used ELISA to detected tumor necrosis factor-α (TNF-α) content in CSF of SAH patients. CSF or recombinant TNF-α were applied on arachnoid cells and T-lymphoctes, and RT-PCR and western blotting were performed to determine the expression of intercellular adhesion molecule-1 (ICAM-1) in arachnoid cells and Lymphocyte Function-Associated Antigen-1 (LFA-1) in T-lymphocytes, respectively. Meanwhile, the Matrix Metal Proteinase-9 (MMP-9) expression in these cells was also determined. We found that the content of TNF-α in the CSF was significantly increased in the CSF of SAH patients (from 22±8 pg/mL of healthy people to 436-450 pg/mL of SAH patients). Treatement with CSF could increase the expression of ICAM-1in arachnoid cells and that of LFA-1 in T-lymphocytes, mainly through the increased levels of TNF-α. We also found that the co-culture of arachnoid cells and T-lymphocytes increased the expression of MMP-9 in both cells through the interaction of ICAM-1 of and LFA-1. All of these results suggested that arachnoid cells are involved in the T-lymphocytes invasion in the subarachnoid space after SAH. © 2013 Elsevier B.V.

Clofazimine has shown activity against Mycobacterium tuberculosis, including multidrug-resistant strains in vitro and in animal studies. However, clinical experience with clofazimine in multidrug-resistant tuberculosis (MDR-TB) is scarce. We reported our clinical experience with 39 MDR-TB patients treated with combination regimens that included clofazimine. From January 2008 to March 2011, 39 patients received clofazimine for the treatment of MDR-TB in Shanghai Pulmonary Hospital. Patients had isolates resistant to a median of six drugs (range, 2-11 drugs). Of the 39 cases, 36 had cavitary changes noted on initial chest radiograph or chest computed tomography, and positive sputum-smear microscopy results at the time of MDR-TB diagnosis. At data censure, 15 of the 39 patients had successful therapy, with at least five consistently negative cultures documented for the final 12 months of treatment. Eleven continued to receive treatment. There were no deaths. Thirteen patients had a poor outcome, including four defaults and nine treatment failures. Culture conversion occurred in 22 cases at a median of 12weeks. Side-effects occurred in 34 patients, mainly including skin discolouration, ichthyosis and gastrointestinal adverse events. No patients reported significant toxicity likely to be attributable to clofazimine therapy. Adverse events were managed by combinations of dose adjustment and symptom management. In our experience, clofazimine was well tolerated and may have efficacy in the treatment of MDR-TB. © 2011 European Society of Clinical Microbiology and Infectious Diseases.

Berberine is an isoquinoline alkaloid present in several plant species, including Coptis sp. and Berberis sp. In traditional medicine, extracts of berberine are used in the treatment of diarrhea of different origins. Recent studies have shown that berberine and its derivatives have significant biological effects on gastrointestinal (GI) and other functions and may become therapeutics for the treatment of diarrhea, gastroenteritis, diabetes, hyperlipidemia, cardiovascular diseases and inflammatory conditions. This paper summarizes the current knowledge on the actions of berberine in the GI tract. Binding and target sites, activated intracellular pathways, as well as the absorption and metabolism of berberine are discussed. Effects that may be useful in future clinical treatment, like antidiarrheal, anti-inflammatory and antitumor effects are critically reviewed and potential clinical applications are presented in detail. © 2014 World Scientific Publishing Company and Institute for Advanced Research in Asian Science and Medicine.

To investigate the clinical results of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for lumbar spinal stenosis with lumbar instability. Retrospective study was done on 42 cases of lumbar spinal stenosis with lumbar instability treated with bilateral decompression via unilateral approach and MIS-TLIF through an expandable tubular retractor from March 2010 to January 2011. There were 18 males and 24 females, and mean age was 61.7 years (rang, 48 - 79 years). The level of surgery was L(3-4) in 4 patients, L(4-5) in 26 patients, and L(5)-S(1) in 12 patients. All patients had symptoms of intermittent claudication. And 24 patients had symptoms of lower extremity pain and numbness in one side, and 18 patients had same symptoms in both legs. Operation time, intra-operative bleeding, postoperative hospital stay and complications were recorded. Visual analogue scale (VAS) scores for low back pain and leg pain were recorded before and after surgery. Oswestry disability index (ODI) scores were also recorded before and after surgery. The Bridwell criterion was used for evaluating the interbody fusion, and the MacNab criterion was used for assessment after surgery. The mean operative time was 150.4 minutes (range, 120 - 170 minutes), and mean blood loss was 147.1 ml (range, 50 - 400 ml). The hospitalization time after surgery was 5 - 18 d, an average of 8.8 d. All cases were followed-up for 6 - 14 months (average 11 months). VAS score of low back pain before surgery was 7.3 ± 1.0, and were 2.9 ± 0.8 and 2.0 ± 0.8 at three months after surgery and the last follow-up respectively. VAS score of leg pain before surgery was 7.9 ± 0.7, and were 2.0 ± 0.5 and 1.0 ± 0.7 at three months after surgery and the last follow-up respectively. ODI score was 75% ± 6% before surgery, were 16% ± 6% and 12% ± 5% at three months after surgery and the last follow-up respectively. VAS and ODI scores showed statistically significant improvements (t = 3.110 - 56.323, P < 0.01). There were 40 cases were grade I and II, according to the Bridwell criteria. The clinical results were excellent in 16 cases, good in 22 cases and fair in 4 cases to the MacNab criteria at the final follow-up. MIS-TLIF is an ideal surgical method for single segment lumbar spinal stenosis with lumbar instability, but close attention should be paid to specific patients, surgeons and hospitals.

Background: MicroRNAs (miRNAs) are small, non-coding RNAs (20-24 nucleotides) that post-transcriptionally modulate gene expression by negatively regulating the stability or translational efficiency of their target mRNAs. The aim of this study was to investigate the expression pattern of microRNA-26b (miR-26b) in human breast cancer, and its potential role in disease pathogenesis. Methods: Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was performed to determine the expression level of miR-26b in 38 breast cancer specimens and adjacent normal breast tissues. MTT assays were conducted to explore the impact of miR-26b overexpression on the proliferation of human MDA-MB-231 breast cancer cells. Luciferase reporter assays were employed to validate regulation of a putative target of miR-26b. The effect of modulating miR-26b on endogenous levels of this target were subsequently confirmed via qRT-PCR and Western blot. Results: MiR-26b expression was relatively decreased in breast cancer specimens compared with adjacent normal tissues (P<0.01). Overexpression of miR-26b suppressed MDA-MB-231 cell growth. Luciferase assays using a reporter carrying a putative miR-26b target site in the 3' untranslated region of PTGS2 revealed that miR-26b directly targets PTGS2. Overexpression of miR-26b led to downregulation of PTGS2 at the mRNA and protein level, as assessed by qRT-PCR and Western blot. Targeted knockdown of PTGS2 by siRNA significantly inhibited the proliferation of MDA-MB-231 breast cancer cells. Conclusions: MiR-26b may act as a tumor suppressor in breast cancer. The overexpression of miR-26b inhibits cellular growth by targeting PTGS2, suggesting its use as a potential therapeutic target for breast cancer. © 2013 Li et al; licensee BioMed Central Ltd.
