Objective To analyze the differences of video laryngoscope, direct laryngoscopy and fibreoptic bron﹣choscope nasal intubation on hemodynamics, inflammatory and stress response. Methods 117 patients underwent surgery from November 2013 to March 2015 were chose as research subjects and randomly divided into video laryn﹣goscope group, direct laryngoscopy group, fiberoptic bronchoscope group based on different cannula enrolled way. Then compared the hemodynamics, inflammation, stress level after intubation among the three groups. Results Com﹣pared with the T0, the three groups patients' systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), C-reactive protein (CRP), interleukin -6 (IL-6), tumor necrosis factor (TNF-α), norepinephrine (NE), plasma cortisol (Cor), angiotensinⅡ(ATⅡ) differences had no significant difference (P>0.05);compared with direct laryn﹣goscopy group, video laryngoscope group, fiberoptic bronchoscope group patients' T1, T2, T3 SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ levels were lower; compared with the video laryngoscope group, optical fiber bron﹣choscopy group patients SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ low levels at T1, T2, T3 were lower (P<0.05). Conclusions Fibreoptic bronchoscope nasal intubation has less influence on patients, will not cause severe stress and inflammatory response, it is one of the ideal instrument anesthesia induction intubation.

The clinical data of a child with perianal necrotizing fasciitis admitted to the Department of Pedia-trics of Guangzhou First People′s Hospital were retrospectively analyzed.The child, girl, more than 5 months old, the clinical features of the onset of fever and diarrhea, only 10 days after the onset, the child′s skin progressed from redness and swelling to perianal skin and soft tissue ulcers, fat liquefaction, visible rectum exposure.After surgical incision, thorough debridement and drainage and selection of sensitive antibiotics, the child recovered and was discharged.Perianal necrotizing fasciitis is a rare necrotizing soft tissue infection caused by a variety of bacterial infections.Because its early performance is difficult to distinguish, the symptoms are serious, and the mortality rate is high.It should been pain attention in clinical work.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion for adjuvant treatment of depression in Parkinson disease and explore its mechanism. Methods: A total of 80 patients with Parkinson disease coupled with depression were randomized into an observation group and a control group, with 40 cases in each group. The control group was treated with levodopa and benserazide hydrochloride tablets and paroxetine tablets, while the observation group was treated with heat-sensitive moxibustion on the basis of the medications in the control group. The treatment course was 2 months. The Hamilton depression scale-17 (HAMD-17), unified Parkinson's disease rating scale (UPDRS) and Parkinson's disease quality of life questionnaire-39 (PDQ-39) were scored before and after the treatment, and the efficacy was evaluated after treatment. Levels of patients' serum dopamine (DA), 5-hydroxytryptamine (5-HT), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before and after the treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). The HAMD-17 scores in the two groups decreased significantly after treatment (both P<0.05), and the score in the observation group was obviously lower than that in the control group (P<0.05). The component scores and total scores of UPDRS in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (all P<0.05). The score of PDQ-39 in the observation group decreased significantly (P<0.05), and was lower than that in the control group (P<0.05). After treatment, the serum DA and 5-HT levels in the observation group increased significantly (both P<0.05) and the TNF-α and IL-6 levels decreased significantly (both P<0.05), which were statistically different from those in the control group (all P<0.05). Conclusion: Heat-sensitive moxibustion has certain auxiliary effect in treating depression in Parkinson disease, significantly improving clinical symptoms and the quality of life, which may be related to the up-regulation of DA and 5-HT levels and down-regulation of TNF-α and IL-6 levels.

ObjectiveTo demonstrate the effect of moderate hypothermia and doule carotid ice applied to acute intracerebral hemorrhage (ICH) and the best opportunity of treatment.Methods174 cases with ICH were randomly divided into treated group and control group, 87 cases for each group. Each case of both groups was treated by routine therapy, moreover, all cases in treated group were treated by moderate hypothermia (MHT).The clinical effect and prognosis between treated group and control group were contrasted,so to do between the cases in the treated group who were treated no more than 3 hours and more than 3 hours after attack.ResultsCompared with the control group, the neurological function improved in the treated group(P<0.05), as well as survival rate and recovery(P<0.05).Cases who treated no more than 3 hours after attack was better than that of more than 3 hours(P<0.05).ConclusionModerate hypothermia can effectively ease the neurologic deficits after ICH, decrease mortality and disable rate.The best therapy time is within 3 hours after ICH.

ObjectiveTo observe the effects of hypoxia inducible factor-1 alpha (HIF-1α)-targeting small interfering RNA(siRNA) on the expression of HIF-1α and vascular endothelial growth factor (VEGF) in HaCaT ceils under hypoxic conditions. MethodsHaCaT cells were cultured and divided into four groups, normal control group (without any treatment), hypoxia group (cultured under hypoxic conditions for 24 hours),liposome control group (transfected with liposome followed by hypoxic culture for 24 hours), RNA interference group (transfected with HIF-1α-targeting siRNA/liposome complexes followed by hypoxic culture for 24 hours). Fluorescence real-time quantitative PCR was utilized to determine HIF-1oα and VEGF mRNA expression in HaCaT cells, and Western blot to detect HIF-1α and VEGF protein expression. ResultsNo significant difference was observed in the mRNA expression of HIF-1α between the hypoxia group and normal control group(0.907 ± 0.032 vs. 0.878 ± 0.034, F =1.108, P ＞ 0.05), while the expression levels of VEGF mRNA,HIF-1α and VEGF proteins were significantly higher in the hypoxia group than in the normal control group (0.935 ± 0.032 vs. 0.652 ± 0.053, 0.813 ± 0.047 vs. 0.236 ± 0.014, 0.791 ± 0.030 vs. 0.316 ± 0.013, all P ＜0.05). A significant decline was noted in the mRNA and protein expression levels of VEGF (0.230 ± 0.044 vs.0.978 ± 0.030, 0.213 ± 0.026 vs. 0.817 ± 0.049, both P ＜ 0.05) and HIF-1α(0.497 ± 0.033 vs. 0.806 ±0.040, 0.249 ± 0.028 vs. 0.833 ± 0.052, both P ＜ 0.05) in the RNA interference group than in the liposome control group. ConclusionsHypoxia may enhance the expression of HIF-1α and VEGF in HaCaT cells, and to inhibit the HIF-1α expression may suppress the expression of VEGF in HaCaT cells under hypoxia.
