Objective It compared the power consumption and electrical parameters between Thulium fiber laser devices(TFL)and Holmium laser devices(HoL)in transurethral enucleation of prostate(TUEP).Methods A sin-gle surgeon conducted TUEP by THL or HoL in 10 patients respectively.The enucleation efficiency,the laser energy output and the electric parameters were recorded and analyzed.Results The data from both groups of surgeries were tested for normal distribution,and the t-test found that the difference in the enucleation efficiency between the two surgeries was not statistically significant(P=0.818),and the energy consumption indexes of the two devices were comparable.The difference in the total kilojoules of laser emission between the two lasers during surgery was not statistically significant(P=0.148),but the power consumption of the thulium laser was about one-tenth of that of the holmium laser(P＜0.001),suggesting that the former utilised electrical energy significantly more efficiently than the latter.The maximum current of the HoL was significantly higher than that of the TFL(P＜0.001),requiring a spe-cial high-power power outlet.Conclusion TFL was superior to HoL in terms of lower power consumption,higher en-ergy-efficient and electrical convenient in transurethral enucleation of the prostate.

Objective To investigate the activated phenotype and the expression of the receptor of advanced glycation endproducts(RAGE)of astrocytes after hypoxic-ischemic brain damage(HIBD)in neonatal rats and the effects of gastrodin(GAS)intervention on them.Methods Totally 48 neonatal 3 days SD rats were used to construct HIBD model and randomly divided into sham group,HIBD group and HIBD+GAS group(100 mg/kg),and the expressions of Al type astrocyte marker C3,A2 type astrocyte marker S100A10,RAGE,tumor necrosis factor-α(TNF-α),brain-derived neurotrophic factor(BDNF),and insulin-like growth factor(IGF-1)in the corpus callosum of the ischemic side were detected by Western blotting and immunohistochemical staining on day 1 and day 3 after HIBD.TNC-1 cells were divided into control group,oxygen glucose deprivation(OGD)group,OGD+GAS(0.34 mmol/L)group and GAS group,and then the protein expressions of RAGE,TNF-α,BDNF and IGF-1 were detected by Western blotting and immunofluorescence.Results In vivo,Western blotting showed that compared with the sham group,the protein expression levels of C3,S100A10,RAGE,TNF-α and IGF-1 in the 1 day and 3 days groups after HIBD group in 1 day group were significantly higher than those in the sham group(P＜0.05),but the protein expression level of BDNF decreased in 1 day group and increased in 3 days group(P＜0.05).Compared with the HIBD group,the C3,RAGE and TNF-α protein expression levels were significantly attenuated in the HIBD+GAS group(P＜0.05),and the protein expression levels of BDNF and IGF-1 further increased(P＜0.05).The protein expression of S100A10 in the 3 days group was higher than that in the HIBD group after GAS treatment(P＜0.05).The immunohistochemical staining results of C3,S100A10,and RAGE in the 1 day and 3 days groups after HIBD were consistent with Western blotting results.Furthermore,the protein expressions of RAGE and TNF-α were significantly enhanced in OGD-stimulated astrocytes(P＜0.05).After GAS intervention,while the expressions of both RAGE and TNF-α decreased significantly(P＜0.05),the expressions of BDNF and IGF-1 increased significantly(P＜0.05).Conclusion With inhibiting the up-regulation of RAGE signal in astrocyte after HIBD and expressions of A1 astrocyte and neuroinflammatory factors,gastrodin can promot the expressions of A2 astrocyte and nutritional factors,which play an important role in neuro-protective effect.

Objective: To examine the safety and effectiveness of a new stent graft system for endovascular repair of abdominal aortic aneurysm(AAA). Methods: This is a prospective,multi-center,single-arm clinical trial. The patients with AAA treated with a new stent graft system were enrolled at 21 centers from September 2018 to September 2019 in China. Follow-up was performed before discharge, and at 30, 180, 360 days after operation, respectively. The primary safety endpoint was the incidence of major adverse events(MAE) within 30 days. The primary efficacy endpoint was the success rate of AAA treatment at 360 days. Secondary safety endpoints were the incidence of perioperative access complications and acute lower limb ischemia,all-cause mortality, AAA related mortality and incidence of serious adverse events (SAE) at 180 and 360 days. Secondary efficacy endpoints were the incidence of type Ⅰ or Ⅲ endoleak,stent displacement,and conversion to open surgery or re-intervention at 180 and 360 days. Results: One hundred and fifty-six patients were enrolled,including 137 males and 19 females. The age was (68.9±6.9) years (range:48.2 to 84.6 years).Maximum aneurysm diameter was (50.8±11.2) mm (range:25.0 to 85.0 mm),diameter of proximal landing zone was (21.2±2.5) mm (range:17.0 to 29.5 mm),and length of proximal landing zone was (31.4±13.0) mm (range:11.0 to 75.0 mm).The incidence of MAE was 1.3% (2/156) at 30 days,both were all-cause death cases. The success rate of AAA treatment was 88.5% (138/156) at 360 days. No perioperative access complication and acute lower limb ischemia occurred. All-cause mortality was 2.0% (3/154) at 180 days and 2.6% (4/153) at 360 days,and there was no AAA related death. The incidence of SAE was 23.0%(35/152) at 180 days and 30.5%(46/151) at 360 days, and no device-related SAE occurred. The incidence of type Ⅰor Ⅲ endoleak was 3.4% (5/147) at 180 days and 3.5% (5/144) at 360 days. Conclusion: The new stent graft system is easy to operate,and early-term safety and effectiveness results are expected.
