【Abstract】 Objective To summarize the effectiveness of surgical removal combined with adjuvant therapy onthe aural region keloid. Methods From January 2000 to December 2005, 42 patients (71 side ears) with keloid at the auralregion were treated. There were 8 males and 34 females, aged 16 to 50 years (mean 26.2 years). The course of diseaseranged from 6 months to 4 years. The causes of disease included earhole piercing (n=32), ear trauma(n=7), and postoperativehyperplasia(n=3); the sizes of keloids ranged from 0.3 cm × 0.3 cm× 0.2 cm to 6.0 cm × 4.0 cm × 1.0 cm with globular, dumb-bell,nodular shapes. According to the different sizes and the range of keloids, different operations to remove the keloids and repairthe defect tissue were chosen. Wounds were exposed to the electron beam at first 24 hours after operation, once a day at 2 Gyeach time for 10 days. An immediate local injection for the keloid with hormones anti-scar drugs, which was a mixture of Betamethasone(Diprospan) and 2% Lidocaine with a proportion of 1 ∶ 3, was given to the patients who had recurrence trend 3 times,every 3 weeks. Results After operation, all the wounds healed by first intention. And 37 cases(64 lateral ears) were followedup for 1 year, and all achieved cl inical cure. Five cases (7 lateral ears) had the trend of recurrence 3-6 months after operation andwere cured after the immediate local injection for the keloid with hormones anti-scar drugs. According to LIU Wenge’s curativecriterion, 37cases were cured and 5 cases responded to treatment. Conclusion Surgical removal combined with local radiationand hormones infiltrated individually as early as possible can effectively treat aural region keloids. And it is an optimal method.

Objective To discuss the performance of multi-disciplinary team (MDT) of colorectal cancer treatment within West China Hospital in Sichuan University. Methods To compare the therapeutic effect between groups of MDT model and non-MDT model by retrospectively analyzing the data of patients who diagnosed colorectal cancer and accepted in-hospital therapy during December 2006 and May 2007. Results The in-hospital days of the MDT model group during the perioperative period and in the surgical ward were less than that of the non-MDT model group ( Plt; 0. 05) , but there was no significant difference between the two groups about the total hospitalization time. And the MDT model group had a higher rate of cancer resection ( P lt; 0. 05) . Although the incidence of anastomotic leakage and bleeding as early postoperative complications didn’t show any variations between the two groups , the non-MDT model groupencountered more early postoperative ileus ( Plt; 0. 05) . During the 5－ 10 months follow-up , there came out less cancer recurrence rate in the MDT model group than the other ( P lt; 0. 05) . And the morbidity of anastomotic stricture and ileus didn’t show any statistical difference between the two groups. Conclusion The combined-therapy st rategy ofcolorectal cancer has showed a priority to routine ways , not only the more reasonable time arrangement for therapy , but also the more satisfied surgical outcomes. However , the factors correlated to the efficacy of the MDT model are not clear ; the MDT model still needs to be improved that a morereasonable and effective perioperative MDT model may come t rue.
Objective To investigate the depression status，score of asthma control test (ACT) and quality of life in asthma patients before and after health care education according to Global Initiative for Asthma guidelines.Methods 59 enrolled outpatients with asthma were asked to self-administer the CES-D (center for epidemiologic studies-depression) scale，ACT scale and the quality of life (QOL) questionnaire respectively.All the patients were educated and treated by health care professionals under the guidance of GINA 2004.After average of 2.5 months ± 15 days，they were asked to self-administer all the scales and questionnaire mentioned above once again on return visit.The data was collected and analyzed statistically based on whether or not the patient had depression according to the CES-D score and the data before and after the education was compared statistically.Results （A）40.7% (24/59) of the patients had depression emotion before guided treatment，and after that the percentage significantly decreased to 13.6% (8/59) (Plt;0.05).（B）Comparing the depressive and non-depressive groups，there was significant difference in 3 of 5 domains in QOL excluding limitation of activity and self concern about health (Plt;0.05) before guided treatment.While on return visit 3 domains in QOL excluding limitation of activity and psychologic status had shown a significant difference (Plt;0.05).There was no significant difference in ACT score before guided treatment，while wise versa after that (Plt;0.05).（C）Before guided treatment the depression status was inversely correlated with 3 in 5 domains of QOL (symptoms of asthma，psychologic status and response to irritant)，as well as QOL as a whole (Plt;0.05)，but not with the other two domains of QOL scale and ACT score.After guided treatment，the depression status had inverse correlation with QOL and 3 in 5 domains of QOL scale (excluding limitation of activity and psychologic status) (Plt;0.05)，as well as ACT score (Plt;0.05).Conclusions The symptoms of asthma and response to irritants are common factors that influence the depressive emotion in asthma population.While psychologic status and self concern about health are both important factors that can not be overlooked.Health care education is important for asthma patients in view of appropriate treatment，symptom control and relief of depression emotion.
ObjectiveTo analyze the clinical and dosimetric impacts on radiation pneumonitis (RP), and provides data for radiotherapy planning. MethodsWe reviewed 59 non-operative esophageal cancer patients who underwent radiotherapy from October 2010 to November 2012 to identify the correlation between the clinical and dosimetric parameters with acute radiation pneumonitis (ARP) and severe acute radiation pneumonitis (SARP) by t-Test, Chi-Square Test and logistic regression analysis. ResultsAmong the 59 patients, 33 (55.9%) developed ARP, in whom 9 (15.3%) developed SARP. Univariate analysis showed that lung infection during radiotherapy, mean lung dose (MLD), and dosimetric parameters are significantly correlated with RP. Multivariate analysis revealed lung infection during radiotherapy, MLD≥13 Gy, and V30≥13% were significantly correlated with the increasing risk RP. ConclusionLung infection during radiotherapy, MLD, and V30 are the influencing factors of RP, which should be seriously considered when formulating radiotherapy plan to avoid RP.
ObjectiveTo investigate clinical outcomes of isolated atrial septal defect (ASD)repair on the beating or non-beating heart through minimally invasive right axillary approach. MethodsForty-five patients underwent isolated ASD repair through minimally invasive right axillary approach in Research Institute of Surgery, Daping Hospital of the Third Military Medical University from September 2009 to August 2011. According to different surgical techniques, all the patients were divided into a beating-heart group and a non-beating heart group. In the beating-heart group, there were 22 patients including 13 males and 9 females with their mean age of 3.2±2.1 years and body weight of 13.1±4.0 kg. There were 20 patients with ostium secundum ASD and 2 patients with ostium primum ASD. Mean ASD diameter in the beating-heart group was 12.2±5.1 mm. In the non-beating heart group, there were 23 patients including 14 males and 9 females with their mean age of 3.5±2.5 years and body weight of 12.9±3.3 kg. There were 18 patients with ostium secundum ASD, 3 patients with sinus venosus ASD, and 2 patients with ostium primum ASD. Mean ASD diameter in the non-beating heart group was 11.6±4.7 mm. Serum creatine kinase (CK), creatine kinase isoenzyme (CK-MB), aspartate aminotransferase (AST)and highly sensitive cardiac troponin I (cTnI)were examined preoperatively, after weaning from cardiopulmonary bypass (CPB), 6 hours and 24 hours postoperatively. ResultsThere was no in-hospital death. Postoperatively, 1 patient had right atelectasis and another patient had right pneumothorax. CPB time and operation time of the beating-heart group were significantly shorter than those of the non-beating heart group (P < 0.05). There was no statistical difference in intraoperative blood transfusion, mechanical ventilation time, length of postoperative ICU stay or hospital stay, chest drainage within 24 hours postoperatively, or postoperative cardiac function between the 2 groups (P > 0.05). Preoperative levels of CK, CK-MB, AST and cTnI were all within the normal limit, and there was no statistical difference between the 2 groups (P > 0.05). After CPB, CK, CK-MB, AST and cTnI levels increased in both groups, but increased significantly greater in the non-beating heart group (P < 0.05). Postoperative levels of CK, CK-MB, AST and cTnI of the beating-heart group were significantly lower than those of the non-beating heart group (P < 0.05). ConclusionIsolated ASD repair on the beating heart via minimally invasive right axillary approach is a safe and cosmetic procedure with shorter operation time and less myocardial injury.
