Objective To investigate the safety and feasibility of early removal of chest tubes after video-assisted thoracoscopic (VAST) lobectomy for lung cancer. Methods A retrospective study was performed based on the clinical data of sixty consecutive patients who underwent VATS lobectomy plus mediastinal lymph nodes dissection for lung cancer from October 2013 to September 2014 in a single center. Thirty patients were enrolled into the early removal management group (chest tubes removal when the drainage volume is less than 300 mL/d), while the other thirty patients were enrolled into the traditional management group (chest tubes removal at the drainage volume less than 100 mL/d ). Results Patients who underwent early removal management had a shorter time of chest tubes removal and postoperative hospital stay compared to the patients in the traditional management group [(2.10 ± 0.99) d vs. (3.83 ± 1.41) d, t = 5.485, P = 0.000; (7.97 ± 1.54) d vs. (9.20 ± 2.01)d, t = 2.669, P = 0.010)]. No statistically significant differences were observed among the drainage volume, postoperative complications and symptoms on fifteen days post-operation. No complication occurred on thirty days post-operation. Conclusions Early removal of the chest tubes after VATS lobectomy ,when the drainage volume is less than 300 mL/d,is safe and feasible. This leads to a shorter length of hospital stay without addtional risk of early postoperative complications.

BACKGROUND: The middle-school stage is the key period of personality figuring and taking shape.The mentation in this period is filled with a lot of special psychological contradictions and conflicts. Long-term psychological worry will affect the formation of perfect personality.OBJECTIVE: To understand the psychological health status in the middle-school students of Zhuang nationality and the main factors of influence.DESIGN: Randomized cluster sampling and questionnaire investigation based on middle-school students.SETTING: Department of Preventive Medicine, Youjiang Medical College of Nationalities.PARTICIPANTS: 2 000 middle-school students of 34 classes from 3 middle schools in Baise City and Longlin County were selected to attend the investigation with randomized cluster sampling method in November 2003.METHODS: The psychological health statuses of middle-school students were evaluated with symptom checklist (SCL).The list contained 90 items,including 9 factors of psychological symptom such as somatization,compulsion,sensitivity to human relations,anxiety,depression,hostility,dread,paranoia and psychosis.The grading system from 1 to 5 grades was used and the standard of the adult norm of the whole country was refered to:Factor score＜1.8 was normal;Factor score from 1.8 to 2.0 was mild abnormality;Factor score from 2.1 to 3.0 was moderate abnormality;Factor score＞3.0 was severe abnormality. Instructive words were unified.The investigative method and behavior were normalized.The questionnaires were filled in without recording the names and taken back from the spot and then compared with the norm of the whole country.MAIN OUTCOME MEASURES: The evaluated result of psychological health in middle-school students.RESULTS: 2 000 questionnaires were provided and 1 855 were valid after return with the effective rate 92.75%. ①The average scores of each factor of SCL were all higher in the middle-school students of Zhuang nationality than in the norm of the whole country. The significance of difference existed(P=0.000).②The scores of somatization,depression,anxiety,dread and psychosis were all higher in the schoolgirls than in the schoolboys.The significance of difference existed (P=0.000).③Except hostility factor,the scores of other factors were higher in the senior middle-school students than in the junior middle-school students.The difference was statistically significant(P=0.000).④The arranged sequences(from bigness to smallness) of each factor that affected psychological health of middle-school students of Zhuang nationality in Baise were depression,somatization,compulsion,anxiety,sensitivity to human relations,psychosis,paranoia,hostility and dread.The sensitivity to human relations ranked 4th and the anxiety ranked 6th in the schoolboys,but the orders of the 2 factors were just the opposite in the schoolgirls and the orders of other factors were the same in both the schoolboys and the schoolgirls.The first 3 factors all were:depression,somatization, compulsion.CONCLUNSION: The psychological health status was lower in the middle-school students of Zhuang nationality than in the norm of the whole country and the first 3 factors that affected their psychological health were:depression,somatization and compulsion. The levels of psychological health on somatization,depression,anxiety,dread and psychosis were lower in the schoolgirls than in the schoolboys. The psychological problems were more serious in the senior middle-school students than in the junior middleschool students. The levels of psychological health in middle-school students of Zhuang nationality were relatively lower and the psychological education and intervention study should be provided aiming at psychological characteristics of different population.

Objective To study the expression of vascular endothelial growth factor (VEGF) and its receptors(VEGFR) mRNA at different time points after focal cerebral ischemic-reperfusion(CIR) in rats. Methods Following the establishment of the of transient ischemia modelof middle cerebral artery in rats by Zea-Longa′s method, the expression of VEGF and its receptors mRNA was measured with semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) at different time points. Results The expression of VEGF mRNA increased 3 h after CIR,and peaked at 6 h, and then declined, returned to the baseline at 7 d. The expression of Flt-1 and Flk-1 mRNA was enhanced at 3 h, and reached its peak at 3 d, then declined gradually. Conclusion The expression of VEGF、Flt-1 and Flk-1 mRNA can be induced by focal CIR in rats.

Objective To explore the expression of growth associated protein-43(GAP-43)in the inferior colliculus in rats following bilateral cochlear ablation.Methods 35 healthy adult SD rats were randomly divided into 7 groups:3,7,14,21,28,90 days following bilateral cochlear ablation and the sham operation group as the control group.The immunohistochemistry was used to observe the expression of GAP-43 after bilateral cochlear ablation in each group.Results GAP-43 was expressed in each group.The GAP-43 expression in bilateral cochlear ablation group were higher than that in the control group.The expression increased at 3 days,followed by a constant increase at 7 to 14 days with the peak on day 14.On day 21 the GAP-43 expression began to decrease.The mean gray level of GAP-43 in all the staining of groups had statistic significance compared to the control group except the group of day 90.However,in all the 7 groups,the mean gray level between the left and right ears had no statistic significance.Conclusion The change of GAP-43 expression in the inferior colliculus following bilateral cochlear ablation reflects synaptic plasticity in inferior colliculus the neurons.

Objective To investigate the effect of remifentanil pretreatment on lipid peroxidation following acute myocardial ischemia/reperfusion (1/R) in rabbits. MethodsForty healthy adult rabbits of both sexes weighing 1.5-2.5 kg were randomly divided into 5 groups (n = 8 each): group control (group Ⅰ ); group I/R(group Ⅱ ); group morphine pretreatment + I/R (group Ⅲ ); group remifentanil (group Ⅳ ) and group remifentanil pretreatment + I/R (group Ⅴ ). The animals were anesthetized with intraperitoneal 2％ pentobarbital 45 mg/kg and were mechanically ventilated after tracheal intubation. PET CO2 was maintained between 35-45 mm Hg. Myocardial I/R was induced by iv pituitrin 2.5 U/kg in group Ⅱ , Ⅲ and Ⅴ. In group Ⅰ and Ⅳ normal saline 0.3 ml/kg was injected iv instead of pituitrin. In group Ⅲ morphine 3.3 mg/kg was injected iv at 30 min before iv pituitrin. In group Ⅳ and V remifentanil was infused at 3.3 μg· kg-1 ·min-1 for 30 min before iv normal saline and pituitrin.Venous blood samples were taken before (baseline) and at 24 h and 48 h after iv pituitrin for determination of serum cTnI concentration. The myocardial specimens were taken at T3 after blood sampling for microscopic examination and determination of SOD activity and MDA content. ResultsIntravenous pituitrin 2.5 U/kg significantly increased serum cTnI concentration and myocardial MDA content and decreased myocardial SOD activity in group Ⅱas compared with group Ⅰ . Morphine or remifentanil preatment significantly attenuated the myocardial I/R-induced changes mentioned above. Microscopic examination showed that myocardial tissue damages were ameliorated in group V as compared with group Ⅱ . ConclusionRemifentanil pretreament can attenuate acute myocardial ischemic injury by inhibiting lipid peroxidation.
