Objective To observe high glucose induced expression of hepatocyte growth factor (HGF) and c met in human kidney fibroblast. Methods The effects of glucose concentrations on expression of HGF, c met and plasminogen activator inhibitor (PAI) 1 in cultured human kidney fibroblasts were observed by RT PCR. In the same system, the effect of exogenous HGF on the expression of PAI 1 was investigated. Results Human kidney fibroblasts cultured in high glucose concentration (25 mmol/L) showed higher HGF and c met expressions in the early stage and then manifested a gradient decrease of HGF and c met expressions, but PAI 1 expression was gradiently increased. Exogenous HGF resulted in inhibiting PAI 1 expression. Conclusion HGF is a potential anti fibrogenic factor and activates matrix degradation pathways in diabetic kidney by reducing PAI 1 expression.

Objective To examine the interrelations among vascular calcification, bone denaity,osteoprotegerin (OPG) and soluble receptor activator of NF-kB ligand (sRANKL) in maintenance hemodialysis (MHD) patients. Methods The levels of serum OPG and sRANKL from 39 MHD patients were measured by ELISA. The vascular calcification was detected by plain radiographs. Bone mineral density (BMD) was measured with dual-energy X-ray absorptionmeter.Interrelations among above parameters were examined statistically. Results (1) Among 39 MHD patients, 25 cases were identified as vascular calcification by radiographic film. The proportion of patients with mild vascular calcification was 41.0% (16 cases), moderate and severe vascular calcification was 23.1% (9 cases). Compared to patients with mild vascular calcification,serum OPG level [(342.50±171.53) ng/L vs (206.21±137.88) ng/L,t=-2.253, P=0.0251 and OPG/sRANKL ratio (454.65±455.63 vs 135.31±136.81, t=59, P=0.035)were significantly higher in patients with moderate and severe vascular calcification,while serum sRANKL level [(0.10±0.08) pmol/L vs (0.12±0.08) pmol/L, t=0.534, P>0.05] was not significantly different. Multiple linear regression analysis showed that OPG/sRANKL ratio was independent factor of vascular calcification score. (2)Compared to patients with normal bone volume, the patients with abnormal bone volume had higher serum OPG level [(249.05±137.66) ng/L vs (226.67±170.12) ng/L], lowerserum sRANKL level [(0.11±0.08) pmol/L vs (0.12±0.02) pmol/L], and higher OPG/sRANKL ratio(202.31±219.24 vs 148.08±210.10), but these parameters were not significantly different betweenthese two groups. Multiple linear regression analysis showed that OPG/sRANKL ratio was anindependent factor of T score of lumbar vertebra. (3)Muhiple linear regression analysis revealed that vascular calcification score was an independent factor of T score of lumbar vertebra and hip.Conclusions Vascular calcification score is an independent factor of BMD of lumbar vertebra and hip in MHD patients. Serum OPG/sRANKL ratio may play an important role in the association between vascular calcification and BMD in MHD patients.

Objective:To compare the clinical effects of discectomy combined with transpedicular dynamic stabilization and transforaminal lumbar interbody fusion (TLIF) in treating single-level lumbar disc herniation.Methods:From November 2012 to November 2015, a total of 96 patients with single-level lumbar disc herniation (disc height decreased more than 1/3, the width of the basilar part of the herniated disc >6 mm, massive disc herniation or Modic type I endplate changes) treated by discectomy combined with Dynesys dynamic stabilization (Dynesys group, n=48) or TLIF (fusion group, n=48) were enrolled. Clinical assessments included operation duration, intraoperative blood loss, MacNab score, visual analogue scale (VAS), Oswestry disability index (ODI) and rate of complications. Radiographs were evaluated for lumbar mobility, intervertebral height, etc. Results:A total of 86 patients were included in the final analysis (44 in Dynesys group and 42 in fusion group) and were evaluated after 5 years follow-up. The operation duration of Dynesys group (159.61±37.29 min) was less than that of the fusion group (177.42±39.90 min) significantly ( t=2.140, P=0.035). Intraoperative blood loss in Dynesys group (151.78±50.88 ml) was less than that in fusion group (197.74±76.55 ml) with significant difference ( t=3.293, P=0.001). At 5 years follow-up, there were 2 cases with screw loosening and 5 cases with adjacent segmental degeneration in Dynesys group without symptom. In fusion group, there were 12 cases with adjacent segmental degeneration and two of them with symptom. There were significant differences in the incidence of adjacent segment degeneration between the two groups ( χ2=4.012, P=0.045). According to the MacNab criteria, excellent or good cases accounted for 95% in Dynesys group and 93% in fusion group without significant differences ( Z=0.425, P=0.671). VAS back, VAS leg and ODI scores were improved significantly in both groups after 2 years and 5 years ( P<0.05). However, there were no significant differences between the two groups ( P<0.05). The activity of the surgical segment was 4.59°±0.48° in Dynesys group and 1.00°±0.42° in fusion group at 5 years after surgery. The height of intervertebral space in Dynesys group decreased from 11.19±2.07 mm before surgery to 9.98±2.02 mm at 2 years after surgery and to 9.86±1.64 mm at 5 years after surgery ( F=6.462, P=0.002). However, there was no statistically significant difference between the 2 and 5 years follow-up ( q=0.415, P>0.05). At 5 years after surgery, the activity of the first proximal segment in the two groups was 9.74°±3.29° and 11.69°±3.89°, respectively ( t=2.514, P=0.014). Conclusion:Both discectomy combined with dynamic stabilization and TLIF can achieve satisfied clinical effects in treating single-level lumbar disc herniation. Dynamic stabilization preserves the intervertebral activity of surgical segments and results in a lower incidence of adjacent segment degeneration compared with that in fusion surgery. Furthermore, discectomy combined with dynamic stabilization is a less invasive intervention with shorter operation duration and less blood loss compared with TLIF.

Rheumatoid arthritis (RA) is a systemic autoimmune disease with local joint pain as the main clinical manifestation. It is one of the diseases specifically responding to traditional Chinese medicine (TCM). The occurrence of RA is not only related to innate factors like genetic disorder but also associated with environmental factors, such as diets and microbial infection. The intestine, a vital human organ with digestive and immune functions, is a place where microorganisms colonize and exert intestinal metabolism-improving, barrier-protecting, and immunomodulatory effects. As the research on the onset and treatment of RA is deepening, the potential relationship of intestinal structural and functional abnormalities with the pathogenesis and progression of RA has been revealed. As clinical and experimental studies indicated, joint inflammation coexists with the impaired barrier function, imbalanced immune cells, and disordered gut microbiota. The theory of the gut-joint axis in the pathogenesis, progression, and treatment of RA is highly consistent with the holistic view in TCM. The recent pharmacological studies have shown that Chinese medicine prescriptions and active components can inhibit inflammation, protect joints, and maintain the intestinal function. This article summarizes the basic connotation of the gut-joint axis in RA and the mechanism by which TCM protect the intestinal barrier and modulate the immunity by regulating the gut microbiota structure and improving microbial metabolism in the treatment of RA. This review gives insights into the future research on the gut-joint axis in RA.

Lung cancer has the highest mortality rate among all malignant tumors. The key to reducing lung cancer mortality is the accurate diagnosis of pulmonary nodules in early-stage lung cancer. Computer-aided diagnostic techniques are considered to have potential beyond human experts for accurate diagnosis of early pulmonary nodules. The detection and classification of pulmonary nodules based on deep learning technology can continuously improve the accuracy of diagnosis through self-learning, and is an important means to achieve computer-aided diagnosis. First, we systematically introduced the application of two dimension convolutional neural network (2D-CNN), three dimension convolutional neural network (3D-CNN) and faster regions convolutional neural network (Faster R-CNN) techniques in the detection of pulmonary nodules. Then we introduced the application of 2D-CNN, 3D-CNN, multi-stream multi-scale convolutional neural network (MMCNN), deep convolutional generative adversarial networks (DCGAN) and transfer learning technology in classification of pulmonary nodules. Finally, we conducted a comprehensive comparative analysis of different deep learning methods in the detection and classification of pulmonary nodules.
