Objective To explore how to treat open neck trauma in time and with reason in the primary hospital.Methods 57 cases of neck open injury were hospitalized from Aug.1997 to Jan.2()07,and injury cause,mechanism,diagnosis and treatment of them are analyzed retrospectively.Results There were 29 incisal wounds and 23 penetrating wounds and 5 contusing wounds.Among 57 patients there were 12 significant injuries and 55 minor injuries cases.53 patients had been treated with operative exploration and 10 patients had therapeutic exploration.The result of treatment showed that 50 patients were cured,and 4 patients died of head injury,cervical spinal injury and respiratory failure,anoxic encephalopathy from airway obstruction and hemorrhagic shock from combined injuries of common carotid artery and internal jugular vein.Conclusion The mainstay of choice of treatment is the injury mechanism and clinical signs and symptoms of patient.

A number of research has shown that the plant polyphenol resveratrol,one of the most prominent small molecules,has beneficial protective effects in multiple organisms,including worms,flies,and killifish.To understand the effects of resveratrol on lifespan,we evaluated its effects in the silkworm Bombyx mori.In this study,we found that lifespan was significantly prolonged in both female and male silkworms treated with resveratrol.Silkworm larval weight was significantly increased from day 3 of the 5th larval instar(L5D3) to day 7 of the 5th larval instar (L5D7).However,the weight of the pupa,cocoon,and total cocoon was not significantly different in female silkworms with resveratrol treatment than that in controls.Meanwhile,resveratrol significantly improved the thermotolerance of the silkworms,which enhanced their survival rate.Moreover,antioxidant activity was increased by resveratrol in both female and male silkworms.Furthermore,an antioxidant-related signalling pathway,SIRT7-FoxO-GST,was activated in silkworms with resveratrol treatment.Collectively,these results help us to understand the molecular pathways underlying resveratrol induced pro-longevity effects and indicate that silkworm is a promising animal model for evaluating the effects of lifespan-extending drugs.

【Objective】 To explore the efficacy of flexible ureteroscopic lithotripsy (FURL) under local anesthesia (LA) in the treatment of upper urinary tract calculi, and to analyze the risk factors of pain. 【Methods】 Clinical data of 255 patients treated during Apr.2022 and Sep.2022 were reviewed, including visual analogue score (VAS) of pain during ureteroscopy, sheath placement, holmium laser lithotripsy, 1 hour and 8 hours after operation. VAS ≥5 was defined as significant pain. Clinical and follow-up data of the significant pain group and non-significant pain group were analyzed with logistic regression to analyze the risk factors of pain in FURL under LA. 【Results】 Altogether 198 patients (77.6%) successfully completed the operation, and the stone-free rate (SFR) was 89.9% (178/198). The VAS of ureteroscopy was the highest (4.49±1.08), and 73 patients (28.6%) experienced significant pain. Univariate analysis showed that significant pain was associated with gender, previous surgical history, age, body mass index (BMI), education level, and ASA classification (P<0.05). Multivariate analysis showed that male (OR=2.896, 95%CI:1.413-5.933, P=0.040) and BMI≥28 (OR=7.776, 95%CI:2.268-26.657, P=0.001) were independent risk factors of significant pain, while age ≥65 years (OR=0.237, 95%CI:0.083-0.672, P=0.007) and previous surgical history (OR=0.156, 95%CI:0.032-0.754, P=0.021) were the protective factors. 【Conclusion】 It is feasible and effective to treat upper urinary tract calculi with FURL under LA. The presence of significant pain is associated with factors such as gender, age, BMI and previous surgical history.
