The influence of different method of mediastinal lymph node excision on perioperative immune function of lung cancer patients / 肿瘤研究与临床

Objective To explore the influence of different method of mediastinal lymph node excision on the immune function of non-small cell lung cancer patients.Metbods Clinical data was collected continuously from 415 cases of inhospital patients with non-small cell lung cancer from March 2009 to March 2012,who were divided into system lymph node dissection group (SLND,216 cases) and lymph node sampling group (LNS,199 cases).The total lymphocytes,NK cells,CD4+ T cells and CD8+ T cells in blood samples taken preoperatively and at 3rd and 7th day postoperation were analyzed.Results Total lymphocytes,NK cells and CD8+ T cells were reduced significantly in the SLND group compared with those in LNS group at 3rd day and 7th day postoperation (3rd day:LC (0.95±0.57) × 109/L vs (1.10±0.65) × 109/L,CD8+ T cells (19.53± 6.48) ％ vs (20.93±6.70) ％,NK (17.36±6.06) ％ vs (18.57±5.97) ％,P ＜ 0.05; 7th day:LC (0.86±0.53) × 109/L vs (1.00±0.60) × 109/L,CD8+ T cells (17.27±5.64) ％ vs (18.40±5.26) ％,NK (13.11±4.84) ％ vs (14.20± 5.30) ％; P ＜ 0.05).CD4+ T cells in the SLND group were reduced significantly at 3rd day postoperation compared with LNS group ((29.59±6.53) ％ vs (31.19±6.32) ％,P ＜ 0.05).Conclusion LNS can reduce immunosuppression compared with SLND for postoperative patients.

Relationship of the fragmented QRS and the fragmented QRS time limit with ventricular arrhythmia in old myocardial infarction / 中国医师进修杂志

ObjectiveTo explore the relationship of the fragmented QRS (fQRS) and the fQRS time limit with ventricular arrhythmia in old myocardial infarction (OMI) patients through contrasting the incidence of ventricular arrhythmia in OMI patients whether fQRS or not and ventricular arrhythmia in different fQRS time limit.MethodsAccording to the routine electrocardiogram,321 OMI patients were divided into group A (fQRS appearance,167 cases) and group B(fQRS non-appearance,154 cases).The lead with fQRS extense was ehosen and traced another 50 mm/s electrocardiogram,and 3 consecutive fQRS time limit were measured and them average was taken in group A.According to the fQRS time limit,the patients in group A were divided into 3 groups: group X( ≤0.100 s,96 cases),group Y (0.101-0.119 s,54 cases) and group Z( ≥0.120 s,17 cases).All the patients were continuously monitored with 24 hours dynamic electrocardiogram,and the incidence of ventricular arrhythmia was analyzed.ResultsThe incidence of ventricular arrhythmia in group A [ 78.4％ ( 131/167 ) ] was higher than that in group B [ 63.6％(98/154) ] (P＜ 0.01 ).The incidence of premature ventricular contraction(PVC) ＞ 720/24 hours in group A [ 28.7％(48/167 ) ] was higher than that in group B[ 17.5％(27/154) ] (P ＜ 0.05 ).The incidence of multifocal PVC,coupled PVC,nonsustained ventricular tachycardia and Lown 3-5 grades PVC was 16.2％ (27/167),33.5％ (56/167),12.0％ (20/167),34.1％ (57/167) in group A,7.8％ (12/154),21.4％ (33/154),4.5％(7/154),23.4％(36/154) in group B,there were significant differences between two groups (P＜ 0.05 ).The incidence of ventricular arrhythmia in group Z [ 100.0％( 17/17 ) ] was significantly higher than that in group Y [79.6％(43/54)] and group X [74.0％(71/96)](P＜ 0.05).The incidence of Lown 3-5 grades PVC in group Z[ 70.6％( 12/17 )] was significantly higher than that in group Y[ 42.6％(23/54)] and group X [ 22.9％(22/96) ],and the incidence of Lown 3-5 grades PVC in group Y was significantly higher than that in group X (P＜ 0.05).ConclusionsOMI patients with fQRS have higher incidence and severe degree in ventricular arrlhythmia than those without fQRS.With the fQRS time limit widened,PVC and Iown 3-5 grades PVC significantly increased.So fQRS is a new predicting index of OMI,and fQRS time limit has definite value in predicting the heart event for OMI patients.

Treatment of superior sulcus tumors using the improved antero-cervical parasternal approach / 中国医师进修杂志

ObjectiveTo investigate the experience of resection of superior sulcus tumors using the improved antero-cervical parastemal approach.MethodsThe clinical data of 3 patients with superior sulcus tumor from July 2005 to May 2010 were analyzed retrospectively.Three patients with superior sulcus tumor underwent en bloc resection using the improved antero-cervical parastemal approach.The 1st to 3rd rib were excised,1 case with 1/5 centrum vertebra excision,1 case with the 1st transverse process of thoracic vertebra excision,1 case with the 1 st and 2nd transverse process of thoracic vertebra excision,1 case with T1 nerve root and sellate ganglion excision.ResultsAll the patients recovered well after operation.There was no serious complication except for 1 case with secondary Horner syndrome.The mild paradoxicalbreathing was found in 3 cases postoperative dressing change,but they had no dyspnea and tolerance well.The paradoxical breathing was disappeared when the mediastinum was fixed after 14 d thoracic wall pressure dressing.The pathological diagnosis after operation:2 cases with squamous-celled carcinoma,1 case with adenosquamous carcinoma,there was no mediastinal lymph node metastasis,cutting edge was negative.Stage:2 cases with T3N0M0,1 case with T4N0M0.Three cases were treated with chemotherapy (NP plan) for 4 cycles after operation without radiotherapy.Three cases were followed up for 53,37, 13 months after operation,they were all survival without recurrence and good quality life.ConclusionsFor the treatment of especially anterior and middle seated superior sulcus tumors,improved antero-cervical parasternal approach provides a safe and effective exposure.The improved antero-cervical parasternal approach is worthy of promotion.

Clinical analysis of autologous serum injection cobined with urokinase through continuous drainage in lumbar occipital angle on encephalocoele hemarrage patients / 中国综合临床

Objective To study the clinical effects of autologous serum injection combined with urokinase through continuous drainage in lumbar occipital angle on encephalocoele hemarrage patients. Methods 106 cases of encephalocoele hemarrage were randomly allocated to treatment group (n = 53) and control group (n = 53). Urokinase injection were applied to both group through double occipital angle puncture, and additional autolagous serum were given to these in treatment group. Results There were 39 cases(73.6%) with effectiveness, 6 cases(11.3%) without any effects and 8 (15.1%) deaths in the control group and in the treatment group, these were 47 (88.7%), 4 (7.5%) and 2 (3.8%) (P < 0.05). The ratio of Hemarrage disappearing in both group are 77.4% and 92.5% respectively (P < 0.05). Conclusion Autologous serum injection combined with tradition treatment is a better alternative.
