ObjectiveTo investigate the efficacy of stellate ganglion block (SGB) on postoperative palpebral edema in patients undergoing intracranial aneurysm surgery. MethodsSixty patients who were scheduled to undergo intracranial aneurysm surgery between September 2012 and Novermber 2014 were recruited, and were assigned into 2 groups randomly with 30 in each:SGB group and control group. Patients in SGB group were administered SGB by injecting 0.3% ropivacaine on the operative side under the ultrasound guidance after surgery completed, while patients in the control group received injection of saline on the operative side under the ultrasound guidance. Incidence of postoperative palpebral edema at hour 24, 48, and 72 after surgery were measured. Numerical rating scale (NRS) was used to detect the severity of uncomfortable symptoms for palpebral swelling during rest state. The severity of palpebral edema was evaluated with continuous rating scale (0-5, 0 indicated normal palpebral, and higher score indicated more serious palpebral edema). Complications related with SGB were recorded. ResultsThe overall incidence of palpebral edema at hour 24 after surgery in SGB group was lower than that in the control group (P<0.05). There was no statistically significant difference in the overall incidence of palpebral edema at hour 48 and 72 after surgery between the two groups (P>0.05). The palpebral edema rating scores of the SGB group at hour 24 after surgery were lower than those of the control group (P<0.01).The incidence of palpebral edema which was scored 3 or more at hour 24 and 48 after surgery in SGB group was lower than that in the control group (P<0.05). No statistically significant difference was found in the incidence of palpebral edema which was scored 3 or more at hour 72 after surgery between the two groups (P>0.05). No complication related with SGB was found. ConclusionSGB can safely reduce the incidence of postoperative palpebral edema in patients undergoing intracranial aneurysm surgery, and reduce the severity of palpebral edema.
Objective To investigate the effects of tobacco smoke exposure on histone deacetylase 2 (HDAC2),interleukin-8(IL-8)and tumor necrosis factor-α(TNF-α)expression in peripheral blood of patients with lung adenocarcinoma and analyze the relationships among them. Methods Seventy-three cases diagnosed as lung adenocarcinoma were collected in the First Affiliated Hospital and Affiliated Tumor Hospital of Guangxi Medical University from April 2014 to March 2015.All patients underwent lung function test preoperatively.Fourteen healthy volunteers without tobacco smoke exposure and chronic obstructive pulmonary disease (COPD)were recruited as healthy control.According to the lung function and tobacco smoke exposure,all cases were divided into four groups,ie. a healthy control group (group A,14 cases),a group without tobacco smoke exposure and COPD(group B,19 cases),a group with tobacco smoke exposure and without COPD(group C,33 cases),and a group with tobacco smoke exposure and COPD(group D,21 cases).The expressions of HDAC2 mRNA,IL-8 mRNA and TNF-α mRNA in peripheral blood mononuclear cells (PBMCs)were detected by real-time polymerase chain reaction (PCR).The contents of IL-8 and TNF-α in serum were detected by ELISA. Results Compared with group A,the HDAC2 mRNA expression in PBMCs had no difference in group B(P>0.05),and was down-regulated significantly in group C and D (P<0.05),which in group D was the most obvious.Compared with group A,the expressions of IL-8 mRNA and TNF-α mRNA in PBMCs and the contents of IL-8 and TNF-α in serum were significantly higher in all lung adenocarcinoma patients(all P<0.05),and the up-regulation was more obvious in group D.The relative expression of HDAC2 mRNA in PBMCs showed no significant difference with respect to age,gender or TNM stage (P>0.05).IL-8 and TNF-α in PBMCs and serum showed no significant difference with respect to age and gender (P>0.05),and were higher in the patients with TNM stage Ⅲ lung adenocarcinoma than those with stage Ⅰ and Ⅱ(P<0.05),with no obvious difference between stage Ⅰ and stage Ⅱ (P>0.05). Conclusion Tobacco smoke exposure causes lower expression of HDAC2 and over-expression of IL-8 and TNF-α in peripheral blood of patients with lung adenocarcinoma,can aggravate inflammatory response especially when complicated with COPD,which may be related to the prognosis of lung adenocarcinoma.
