MethodsBefore sling exercise therapy (SET), 22 patients with chronic nonspecific low back pain were measured the rotary strength of core muscles of trunks with Proxomed Tergumed functional spinal evaluation and training system and the core stability of the low back with SET system. Their correlation was analyzed. ResultsThe core rotary strength was positively correlated with the local stability in patients with chronic nonspecific low back pain (r=0.876, P<0.001). ConclusionIncreasing the rotary strength of trunks is important to improve local stability in patients with chronic nonspecific low back pain.

Objective To investigate the effects of Zafirlukast on emotions and Th1/Th2 cytokines in asthmatic children.Methods One hundred and eight asthmatic children were randomly allocated to 3 groups.The children in group A inhaled Pulmicort aerosol 200 ?g twice every day.On the basis of inhaled Pulmicort aerosol,the children in group B took orally Zafirlukast orally 10 mg once every day.The children in group C only took orally Zafirlukast 10 mg once every day.The course of treatment of all children were 4 weeks.Anxiety,depression status and the levels of IFN-? and IL-4 in blood serum were respectively detected before and after treatment.Results Scores of anxiety and depression after treatment in 3 groups were significantly lower than those before treatment(Pa0.05).Conclusions Zafirlukast or Glucocorticoid inhalation has the same effect on improving emotional status and accommodating disequilibrium of Th1/Th2 for asthmatic children,but effect of Zafirlukast combined with Glucocorticoid inhalation are better.

AIM: To investigate the effectiveness and safety of intravitreal injection of anti-vascular endothelial growth factors (VEGF) drugs to the patients with proliferative diabetic retinopathy before vitrectomy treatment.METHODS: A Meta-analysis.A comprehensive retrieval was conducted using the database including EMbase,the Cochrane Library,Pubmed,CBM,WanFang Database,CNKI and so on.The retrieval time was limited from the building time of database to Jan.2017.The randomized controlled trial was adopted with no requirements on languages.The Jadad scale and Cochrance cooperation were used as the tool of the risk and bias evaluation to analyze the literature quality.Quality estimation of evidence-based medicine on the parameters of each evaluation index was made via GRADEpro Software.The publishing biases of enclosed documents were inspected with funnel plot.At last,the Meta analysis was conducted with Review Manager 5.3.RESULTS: Totally 16 literatures published from 2008-2016 were finally put into randomized controlled trial.A total of 923 cases were included,among which 493 cases were grouped as intravitreal injection of anti-VEGF before the combined operation of PPV group (the experimental group),and 430 cases were involved in simple PPV group (the control group).The results of Meta-analysis show: (1) The probability of intraoperative bleeding was remarkably lower than the control group [OR=0.06,95%CI (0.02,0.15),P<0.01],with statistically significant differences.(2) The duration of operation was obviously shorter than that of the control group[WMD=-29.13,95% CI (-36.95,-21.30),P<0.01],with statistically significant differences.(3) The probabilities of both early and late postoperative vitreous hemorrhage were lower than those of the control group[OR=0.34,95%CI (0.20,0.58),P<0.01],with highly statistically significant differences.(4) The best corrected visual acuity after surgery was no better than that of the control group,[WMD=-0.51(LogMAR),95%CI(-1.10,0.08),P=0.09] with no statistical significance.(5) The occurrence of iatrogenic retinal rupture was lower than that of the control group[OR=0.24,95%CI(0.14,0.40),P<0.01],with statistically significant differences.(6)Among the 493 patients included in the 16 literature,no case of ocular and general adverse effects due to anti-VEGF injections was reported.CONCLUSION: It is effective and safe for the patients with proliferative diabetic retinopathy to inject anti-VEGF drugs into vitreous cavity before vitrectomy.And it can reduce the occurrence of complications during and after surgery,improving the general treatment effects.However,the specific implementation plans,such as the injection does,the interval between the injection and the operation and so on,still need further exploration and perfection.

The corneal reconstruction is tosurgial recover the structure integrity and corneal function after suffered from various trauma, inflammation and degenerative diseases.The corneal diseases caused millions of people worldwide suffering from eyesight damages and even blindness.At present, the corneal transplant is the main therapy for corneal blindness.However, the shortage in donor corneal issue is a worldwide problem and the failure due to the immunologic rejection of host is common.Nowadays, with the development of tissue culture and bioengineering technology, the application prospect of autologous stem cell transplantation is becoming more and more popular which might replace the allogeneic transplantation, becoming an important clinical treatment of regenerative medicine.Human dental pulp stem cells (hDPSCs) is a class of adult stem cell divided from the third molar teeth.Both hDPSCs and corneal cell are from the cranial nerve in embryonic ectoderm.Extensive researches show that the hDPSCs have the potentialities in corneal cell differentiation without causing immunologic rejection of the recipient.These findings manifested the potentials of hDPSCs in the clinical applications related to ocular surface reconstruction.In this paper, the features and current investigation status of hDPSCs in ocular surface reconstruction are reviewed.

Background Oxidative damage is a major cause of age-related cataracts,and the ubiquitinproteasome system is involved in lens differentiation and development.Ubiquitin carboxy-terminal hydrolase L1 (UCHL1),one of key enzymes of ubiquitin-proteasome system,was discovered to participate in the age related diseases and oxidative stress damage. Objective This study was to investigate the effects of UCHL1 on the formation and development of age-related cataract. Methods Lens capsule were collected from 24 patients with age-related cataract(including 12 cases of cortical cataract and 12 cases of nuclear cataract) during the surgery.Five normal lens capsule membranes were obtained from eye bank of Tongji University.Human lens epithelial cells (LECs) line (SRA01/04) was also collected in this study.Expression of UCHL1 in the lens epithelial layer of different samples was assayed using immunofluorescence technology.UCHL1 eukaryotic expressing vector was constructed and transfected into cultured SRA01/04 by liposome,and green fluorescent protein (GFP) eukaryotic expressing vector was transfected at the same method as the control group.UCHL1 over-expressing cells were then exposed to different concentrations (0.2,0.3,0.4 and 0.5 mol/L) of tert-butyl hydroperoxide (TBHP) for 24 hours and subsequently monitored for cell viability evaluation by MTT assay. Results Immunofluorescence showed that UCHL1 was expressed in human lens epithelial layer,but significantly different expressing levels were seen among normal lens capsular membrane,cortical cataract and nuclear cataract ( F =13.411,P =0.000),and UCHL1 expressing levels were lower in cortical cataract and nuclear cataract than the normal lens (P =0.000,P =0.000).No significant difference was found in UCHL1 expressing level between cortical cataract and nuclear cataract ( P =0.164).Western blot analysis verified that UCHL1 exhibited a stranger expression in the UCHL1 transfected group compared with the GFP transfected group,illuminating a successful transfection of UCHL1 in SRA01/04 cells.MMT assay revealed that the A570/630 value in UCHL1 transfected cells was significantly elevated in comparison with GFP transfected cells following the treatment of 0.3 mol/L TBHP. Conclusions UCHL1 has an antioxidative ability,and it might plays an important role in the progress of age-related cataract.

Objective To explore the expression of brain-derived neurotrophic factor(BDNF) and highaffinity receptors tropomyosin receptor kinase B(TrkB) protien in the prefrontal cortex of the post stroke depression in the rats.Methods Focal cerebral ischemic rat models were made with thread embolization method.Post stroke depression rat models were established with comprehensive separately breeding and chronic unpredicted mild stress (CUMS) on this basis.Normal control group,depression group and stroke group were used to compared with PSD group.6 rats were used in each group.Immunohistochemistry for detecting the expression of BDNF and TrkB in the prefrontal was used at 29th day since the CUMS.Results The number of BNDF immunopositive cells in PSD group was the least ((21.00 ± 12.41) per microscope field of vision) than other groups.Whereas there was no statistical difference among groups(P＞ 0.05).The number of TrkB immunopositive cells in the prefrontal cortex in PSD group was the least (20.78 ± 7.20) among three groups,and depreesion group was secondary (21.00 ±5.61).Stroke group has the most number of immunopositive cells(31.67 ± 7.38) in the prefrontal cortex among four groups.One way ANOVA statistical analysis showed the number of TrkB immunopositive cells decreased significantly in the PSD group and depression group compared with stroke group (P＜0.05).Conclusion The downregulation of TrkB immunopositive cells in the prefrontal cortex may be responsible for the pathogenesis of PSD.
