Objective To compare the safety and efficacy of greenlight photos selective vaporization and RevoLix 2 micron continuous wave laser vaporesection for the treatment of superficial bladder tumor. Methods Under sacral anesthesia or epidural anesthesia,a total of 42 patients with superficial bladder tumor were treated with greenlight photos selective vaporization while the other 42 patients received the RevoLix 2 micron continuous wave laser Vaporesection. The clinical stage of the patients was T1-T2,and the pathology grade was G1-G2. Results The greenlight photos selective vaporization and RevoLix 2 micron continuous wave laser vaporesection were successfully completed in all of the patients. No patients required blood transfusion. No complications such as obturator nerve reflex,bladder perforation or overhydration occurred. No significant difference was noticed in the operation time [(15.3?10.5) min vs (14.3?6.5) min,t=0.525,P=0.601],catheterization time [(6.3?0.5) d vs (6.3?1.2) d,t=0.000,P=0.999],and postoperative hospital stay [(6.3?3.5) d vs (7.2?2.4) d,t=-1.374,P=0.173]. The patients were followed up for 6 months,during the period the recurrence rate was 11.9%(5/42) and 7.1%(3/42) respectively in the greenlight group and RevoLix group (?2=0.138,P=0.710). Conclusions Both greenlight photos selective vaporization and RevoLix 2 micron continuous wave laser vaporesection are effective and safe for superficial bladder tumor and lead to low rates of postoperative complications and recurrence. Further studies are necessary to evaluate its long-term effect. For T2 and higher grades of bladder tumors,open surgery should be performed.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

Aiming at local field potential, the present paper introduces a method of estimating lag of neuron activities between brain areas based on windowed Harmonic wavelet transform (WHWT). Firstly, the WHWT of signals of two brain areas are calculated. Secondly, the instantaneous amplitude of the signals is calculated and finally, these amplitudes are cross-correlated and the lag at which the cross-correlation peak occurs is determined as the lag of neurons activities. Comparing with amplitude cross-correlation based on Gabor wavelet transform (GWT) or Hilbert transform (HT), this method is more precise and efficient in estimating the directionality and lag.

AIM: To compare the visual acuity and contrast sensitivity of eyes with different corneal spherical aberration implanted with the same aspherical IOL and evaluate the effect of different ocular spherical aberration on visual performance after phacoemulsification.
METHODS:It was a prospective case series study. Forty-six eyes of thirty-nine age-related cataract patients in our department were included. The patients were divided into 3 groups according to the value of preoperative corneal spherical aberration. Eyes with corneal spherical aberration≤0. 2μm were assigned to group A, those with corneal spherical aberration >0. 2μm and ≤0. 3μm to group B, and those with corneal spherical aberration≥ 0. 3μm to group C. All patients underwent phacoemulcification and recieved AcrySof IQ aspheric IOL. Uncorrected visual acuity ( UCVA ) , best-corrected visual acuity( BCVA) , contrast sensitivity, and total ocular higher - order aberrations for a 6. 0mm pupil were recorded 3mo postoperatively. ANOVA were used to analyze the data.
RESULTS: There were no significant differences in UCVA and BCVA between the 3 groups (P=0. 287, 0. 115). Contrast sensitivity was no statistically significant difference between the 3 groups at any spatial frequency under photopic、 mesopic, and mesopic with glare conditions (P>0. 05). With a 6. 0mm pupil diameter, root mean square values for total ocular higher - order aberrations were lower in groups A and B than that in group C (P=0. 000). The difference of total ocular spherical aberration was statistically significant between the 3 groups (P=0. 000). Coma and trefoil were similar between the groups (P=0. 788,0. 590), with no statistically significant differences.CONCLUSION:Implantation of the same aspherical IOL in eyes with different corneal spherical aberration results in similar visual acuity and contrast sensitivity. Small differences of ocular spherical aberration after phacoemulsification have no effect on visual performance.

BACKGROUND:Stem cel s with wide variety of sources have the potential of differentiation and self-renewal. In additional, autologous stem cel s can avoid immune rejection after transplantation, and thus it has become one of the most promising alternative strategies for tissue/organ transplantation. However, due to the adverse environments at injured sites, such as oxidative stress and inflammation, current stem cel transplantation efficacy is relatively low. OBJECTIVE:To review the effects of oxidative stress on stem cel s and on their transplantation efficiency as wel as relevant mechanisms. METHODS:PubMed database was searched by the first author for relevant articles about stem cel s published from 1990 to 2015. The keywords were“stem cel transplantation, stem cel , oxidative stress, molecular mechanism”. After eliminating literatures which had poor authority or similar content, 97 articles were involved in result analysis. RESULTS AND CONCLUSION:Different types of stem cel s have different basal endogenous antioxidant stress levels. Oxidative stress through multiple molecular pathways causes cel aging, apoptosis and cancer, which also can result in apoptosis of cancer cel s. Stem cel s can adjust endogenous antioxidant levels through multiple paths. To improve the endogenous antioxidant stress level using a variety of methods can increase stem cel transplantation efficiency and prevent stem cel cancerization due to oxidative stress, which makes the clinical application of stem cel transplantation therapy safer and more popular.

Objective To explore the effects of Sanban manipulation of spine on ankylosing spondylitis (AS) at the early-middle stage.Methods 60 AS patients at the early-middle stage were divided into drug group (n=30) and manipulation group (n=30). The drug group wastreated with sulfasalazine and the sustained-release pills of Zhengqingfengtongning, while the manipulation group were treated with Sanbanmanipulation of spine additionally. Self-developed questionnaire were used to follow up before and 1, 3 and 6 months after treatment. ResultsThe Schober index and the finger-floor distance improved more in the manipulation group than in the drug group (P<0.05) 3 months aftertreatment. All the index improved more in the manipulation group than in the drug group (P<0.05) 6 months after treatment. ConclusionSanban manipulation of spine can improve the thoracolumbar activities in the AS patients at the early-middle stage.

italic>γ-Aminobutyric acid (GABA) is a crucial inhibitory neurotransmitter found in various cells in the human body. While the GABAergic system is typically associated with the nervous system, recent research has revealed that immune cells and tumor cells also express components of this system. In the tumor microenvironment (TME), GABA is secreted to act extracellularly on other cells. GABA is metabolized
