BACKGROUND:Lumbar degenerative disease is a common and frequently occurring disease in spinal surgery. With increasing age, the incidence rate is increased. OBJECTIVE: To elevate clinical outcomes and improve the quality of life of patients by analyzing spinal stability after lumbar implant fixation fusion and functional training in treatment of lumbar degenerative disease. METHODS: (1) We used a prospective randomized controled design. The 52 patients with I° or II° degenerative lumbar spondylolisthesis were randomly divided into two groups, with 26 cases in each group. Conventional exercises were carried out in the control group and core stabilization exercises for the treatment group, with course of treatment for 24 weeks. Curative effects of numerical rating scale and the Oswestry Disability Index were compared at 6, 12 and 24 weeks after treatment respectively. (2) Spinal stability after lumbar fusion and fixation of the implant for degenerative lumbar spondylolisthesis was evaluated by database document retrieval. RESULTS AND CONCLUSION:(1) After 24 weeks, numerical rating scale score and the Oswestry Disability Index were significantly lower in the treatment group than in the control group (P < 0.05 orP < 0.01). Core stabilization exercises apparently relieve lumbar pain and improve the ability of activities. Core stabilization exercises are better than conventional training. (2) Pedicle instrument fixation combined with interbody fusion is effective for lumbar spondylolisthesis within the second degree. Posterior interbody fusion has predominant mechanical property in maintaining spondylolisthesis orthopedic and stabilizing the structure. Correction loss and fixation failure easily occur after posterolateral fusion, but clinical effects are not affected.

BACKGROUND:Hematopoietic stem cel transplantation is a promising treatment for a variety of malignant and nonmalignant disorders. But noninfectious pulmonary complications folowing hematopoietic stem cel transplantation are a major cause of morbidity and mortality in these patients. And the diagnosis and treatment are difficult. OBJECTIVE: To review the noninfectious pulmonary complications after hematopoietic stem cel transplantation in terms of onset time, risk factors, clinical manifestations, characteristics of the high-resolution CT, histopathological measurement, related genes and treatment options. METHODS: A computer-based search of VIP, PubMed and Sciencedirect databases was performed for articles related to noninfectious pulmonary compli cations after hematopoietic stem cel transplantation published from January 2005 to October 2014. The key words were “HSCT, pulmonary complications, non-infectious, pirfenidone” in Chinese and English in the title and abstract. Finaly, 31 articles were included in result analysis. RESULTS AND CONCLUSION: The incidence of noninfectious pulmonary complications after hematopoietic stem cel transplantation has become more and more, with atypical clinical manifestations and limited diagnosis and treatments. According to the different clinical onset time, diagnostic criteria, clinical manifestations and the appropriate laboratory tests, clinicians can make early diagnosis and early intervention. Especialy, the usage of high-resolution chest CT and bronchofiberscope for bronchoalveolar lavage as wel as the timely drug administration can improve the survival rate of patients with noninfectious pulmonary complications after hematopoietic stem cel transplantation.

Objective To study the effect of resveratrol on hepatitis B virus (HBV) and hepatic fibrosis.Methods The rat model of HBV infection was established by intraperitoneal injection of rAAV8-1.3HBV.After successfully establishing the modle, were randomly divided into four groups:negative control group, resveratrol low dose group, high dose group, positive control group, and five rats in each group.Giving a physiological saline, 20 mg/kg respectively resveratrol, 40 mg/kg, 0.1 mg/kg acyclovir via gastrogavage respectively.2、4、8、12 weeks later ,we detected the HBsAg, HBeAg, HBV-DNA via tail vein blooding.HSC-T6 cell model was established.Then rats were divided into two groups, control and resveratrol serum group.Each group was administrated with normal sodium and resveratrol via gastrogavage to make serum.The HSC-T6 viability was observed by AlamarBlue assay.The expression of Col I and TGP-β1 mRNA was determined by Realtime PCR.The expressions of Col I and TGP-β1 Protein was analyzed by WesternBlot.Results Using ELISA method to detect HBsAg、HBeAg、HBV-DNA and found that the expression of HBsAg and HBeAg of negative control group were significantly higher than the rest of the three groups (P<0.05) at the second and the fourth week.The highest expression of HBsAg and HBeAg were (4118 ±367) IU/mL、(160.2 ±56.90) NCU/mL at the second week.The expression of HBV-DNA of negative control group is significantly higher than the rest of the three groups (P<0.05) at the second week.AlamarBlue assay indicated that different concentration of serum of resveratrol can inhibit HSC-T6 proliferation.Compared with control group, serum with drug resveratrol significantly down-regulated the mRNA and protein expression of Col I and TGP-β1.Conclusion Resveratrol inhibits HBV and liver fibrosis by inhibiting type I collagen and TGF-β1.

Objective Bone defect repair remains a challenge in regenerative medicine, which has triggered a research upsurge on improving the bone repairing effect using heterogeneous bone combined with growth factors.The aim of this study was to evaluate local bone formation following surgical implantation of coralline hydroxyapatite (CHA), a heterogeneous bone, in combination with the concentrated growth factor (CGF).Methods This randomized prospective study included 24 New Zealand rabbits, which were equally divided into a CHA/CGF+CHA, a CHA/CGF+autograft and a CHA+autograft group.A defect 10 mm in diameter was made in the parietal bone of each animal and filled with CHA/CGF, CHA or autograft.At 6 and12 weeks after the operation, we observed the bone formation by micro-CT and histological examination.Results The bone volume (BV) was significantly higher in the CHA/CGF+CHA than in the CHA+autograft group both at 6 weeks ([39.00±7.61] vs [32.12±6.55] mm3, P<0.05) and at 12 weeks after the operation ([49.75±2.36] vs [39.45±7.02] mm3, P<0.05), and so was the bone mineral density (BMD) ([308.30±29.82] vs [256.85±151.25] mg/mL, P<0.05;[389.00±31.87] vs [302.53±127.05] mg/mL, P<0.05).Histological examination showed that the new bone was distributed throughout the CHA scaffold in the CGF/CHA group at 6 weeks, and the new bone was observed only in the periphery region of the CHA scaffold in the CHA group.The bone defects in the CGF/CHA group were fully repaired at 12 weeks, while those in the CHA group were partly repaired with bone and fibrous tissue in the central region of the defects.Conclusion Combination of CHA with CGF could effectively enhance bone healing.CHA/CGF compound artificial bone is an ideal substitute in bone transplantation.

Objective\ The adrenal gland is a linkage between nervous system and endocrine system.Its cortex results from mesoderm,and medulla derives from neuroectoderm.Searching its double characteristic of nervous and endocrine tissue is our aim. Methods\ Histochemical and immunohistochemical staining techniques were used,and immunostained sections were observed under a light microscopy. Results\ NPY positive neuron and nerve fiber,CGRP positive nerve fiber existed in adrenal cortex.NADPH d positive neuron and nerve fiber, c fos positive neuron and nerve fiber,CGRP positive nerve fiber,SP positive nerve fiber were detected in adrenal medulla.NADPH d positive cell,NPY positive cell,CGRP positive cell,SP positive cell were found among the adrenal chromaffin cells.The zona glomerulosa,zone fasciculata and zona reticularis were stained strongly by NADPH d in cortex. Conclusion\ The adrenal gland was innervated by NO ergic,NPY ergic,CGRP ergic,SP ergic, c fos ergic nerves.The adrenal parenchyma,especially chromaffin cells can produce NO,NPY,CGRP,SP which regulate adrenal endocrine by itself.The nervous control of adrenal function and neuroendocrine function of adrenal gland is more complex than hitherto believed.\;

Objective Our purpose is to explore the occurrence and distribution of glutamate and metabotropic glutamate receptor in earthworm, P. aspergillum and to analyze their function significance. Methods By employing immunocytochemistry tchnique, the positive cells of glutamate and metabotropic glutamate receptor, mGluR1, mGluR2/3, mGluR4 in earthworm, P. aspergillum were investigated under a light microscope. Results It was found that glutamate positive cells existed in cerebroganglion, subpharyngeal ganglion, ventral ganglion, neurons between muscle cells,intestinal epithelium and epidermis, that thin and dense glutamate positive fibers distributed in pharyngeal nerve cycle, subpharyngeal ganglion, ventral neurochain, that mGluR1 or mGluR4 positive neurons were detected in cerebroganglion and mGluR2/3 positive neurons weren't observed in earthworm. Conclusion During glutamate positive neurons, some possess remarkable processes and matured appearance from which glutamate positive fibers in pharyngeal nerve cycle, subpharyngeal ganglion, ventral neurochain derive, another have few branches, unmatured appearance in which glutamate doesn't serve as neurotransmitter acting to mGluR1 or mGluR4 of neurons in earthworm cerebroganglion.
