The injuries caused by earthquake were characterized as complicated injuries, multiple injuries, crush injury, commonly accompanied by the impairment of the organs, open wound with susceptibility to contamination, difficulties in the implementation of in-time treatment, and resource-limited settings. Considering the specialty of early treatment of earthquake victims and existing misconduct, we propose recommendations according to general principles of early rationale use of antibiotics, in order to treat the earthquake victims safely, effectively and feasibly, and to decrease wound infection rates after surgery.
Objective To evaluate long-term effectiveness of recombinant human growth hormone (rhGH) for children with idiopathic short stature (ISS). Methods The randomized controlled trials (RCTs) about rhGH in treating ISS published from 1985 to 2010 were searched in PubMed, ScienceDirect, EBSCOHost, EMbase, The Cochrane Library, CBM, CNKI and VIP. According to the Cochrane Handbook, two reviewers independently screened literature, extracted data, assessed methodological quality, and conducted meta-analysis using RevMan 5.0 software. Results A total of 11 RCTs involving 607 ISS children were included. The results of meta-analysis showed that, compared with the blank/placebo control group after 1-year treatment, the rhGH group resulted in a significant increase in height standard deviation score (SDS) (MD=0.29, 95%CI 0.03 to 0.54, P=0.03), growth velocity (MD=2.68 cm/year, 95%CI 1.70 to 3.65, Plt;0.000 01), and adult SDS (MD=0.46, 95%CI 0.29 to 0.63, Plt;0.000 01). Conclusion rhGH can effectively promote the growth of ISS children. But due to the limitation of quality and small sample size of the included studies, its effectiveness still needs to be further proved by more high quality RCTs.

Methods: From December 2007 to March 2009, 29 patients were treated with tricuspid valve annuloplasty. These were 16 patients in modified De Vega annuloplasty group and the others (13 patients) in traditional De Vega annuloplasty group. The grade of tricuspid regurgitation、New York Heart Association (NYHA) functional class、ejection fraction (EF) and the right ventricular enddiastolic dimension of two groups were followed and reviewed. Results: There was no statistically difference between two groups about preoperative characteristics and followup time. There was 1 patient with severe TR, 5 patients with moderate TR, 5 patients with mild TR and 2 patients without TR in traditional De Vega annuloplasty group after the operations. In modified De Vega annuloplasty group, no patient was observed with severe or moderate TR, 8 patients with mild TR, and 8 patients without TR. At interval time, there was significant difference in the grade of tricuspid regurgitation between two groups (Plt;0. 05). Both tricuspid valve plasty techniques could reduce the right ventricular enddiastolic dimension and improve ejection fraction significantly (Plt; 0. 05), and there was significant difference in the right ventricular enddiastolic dimension and ejection fraction at interval time between two groups (Plt;0.05). Conclusions: The outcome of modified tricuspid De Vega technique is superior to that of traditional De Vega technique in correcting severe tricuspid regurgitation.

Objective To compare BODE index with GOLD staging for the severity evaluation in patients with chronic obstructive pulmonary disease ( COPD) . To investigate the relationship between BODE index and quality of life. Methods A total of 100 patients with stable COPD were enrolled. All participants were examined with lung function test and St George’s Respiratory Questionnaire ( SGRQ) for evaluation of quality of life. BODE index and it’s four components including body mass index( BMI) , airflow obstruction ( FEV1%pred) , dyspnea( MMRC) , and exercise capacity( 6MWD) were calculated. The participants were divided into four groups of severity using GOLD guidelines and BODE index quartiles. Results The associations between SGRQ total score and SGRQ subscales, and BODE index were significant( P lt;0. 01) .BODE index was a significant predictor of the quality of life, explaining 41. 3% of the total score of the SGRQ ( P lt;0. 01) . However, GOLD classification showed a correlation only with SGRQ activity score ( P lt;0. 05) but not with other SGRQ scores. There were significant differences in SGRQ total score and SGRQsubscales between different severity groups of BODE index( P lt;0. 01) . But there was no difference in SGRQ score between different severity groups of GOLD classification, except SGRQ activity score. Conclusion BODE scoring system is better correlated with the quality of life as assessed by the disease severity inpatients with COPD than the GOLD staging criteria.
Abstract: Objective To summarize the clinical experiences of videoassisted thoracoscopic surgery (VATS) lobectomy performed on a series of 300 consecutive patients, and report the results of a 3year followup. Methods We retrospectively analyzed the clinical data of 300 consecutive patients who underwent VATS lobectomy from September 2006 to December 2009 in the Department of Thoracic Surgery, People’s Hospital of Peking University. Of the 300 patients, there were 159 males and 141 females with the age ranged from 18 to 86 years (58.30±13.90 years). Preoperative diagnosis showed that there were 266 patients of mass in the lung, 22 of bronchiectasis, 5 of cyst/abscess in the lung, 3 of pulmonary sequestration, 2 of fungus infection, and 2 of pneumothorax. We assessed the perioperative variables by standard descriptive statistics and estimated the 3year survival rate by KaplanMeier analyses. Results Sixtysix patients were diagnosed to have benign diseases and 234 patients were with malignancies. A percentage of 81.82% (54/66) of the benign patients had infectious diseases, and the majority of the malignancies was nonsmall cell lung cancer (213 patients), especially adenocarcinomas which comprised 73.08% (171/234) of all the malignancies. A total of 273 patients accomplished VATS lobectomy, of whom 27 patients required conversion to thoracotomy at a conversion rate of 9.00%(27/300). In the VATS lobectomy accomplished group, the mean operation time was 317±088 h, and the blood loss was 225.70±195.20 ml. Benign surgery took significantly less time (t=2.280, P=0.0032) and had shorter drainage time(t=1.392, P=0.0304) than those of malignancies. Dense adhesions between lymph nodes and blood vessels was the primary reason for conversion to thoracotomy in 17 patients at a percentage of 62.96%(17/27). Bleeding was the second reason for conversion in 5 patients at a percentage of 1852%. The patients in the upper lobe lobectomy group showed significantly higher risk of conversion compared with those in the nonupper lobe surgery group (χ2=6.131, P=0.013), while gender (χ2=1.182, P=0.277), pathology (χ2=0.210, P=0.647) and the tumor located in left or right side(χ2=2.933, P=0.087) didn’t influence the risk of conversion. The result of the 3year followup showed that there was no reoccurrence of symptoms in patients with benign diseases; Nonsmall cell lung cancer patients had a 3year survival rate of 0.87 with the 95% confidence interval (CI) from 0.77 to 0.96, and pathologic stage I patients at 0.91 with the 95%CI from 0.85 to 0.98. Conclusion VATS lobectomy is safe and effective. This research shows that domestic technologies of VATS lobectomy and its midterm results have reached the international standard.
Objective To find out the best time and investigate the indications for conversion to horacotomy in completely thoracoscopic lobectomy. Methods Between Sep. 2006 and Feb. 2009, 172 patients including 88 male and 84 female with the median age of 58.9 years, underwent completely thoracoscopic lobectomy. Postoperative pathology showed that there were 133 cases of primary lung cancer, 7 cases of lung cancer metastasis and other malignant tumors, and 32 cases of benign diseases. Among them, 46 patients had the tumor on the right upper lobe (RUL), 23 on the right middle lobe (RML), 31 on the right lower lobe (RLL), 36 on the left upper lobe (LUL) and 36 on the left lower lobe (LLL). Three incisions were made in all operations. The procedures of systematic lymphadenectomy and anatomic lobectomy were similar with routine thoracotomy. If there was mediastinal lymph node adhesion, metastasis or bleeding, the incision would be extended to 12-15 cm and the surgery would be converted to thoracotomy. According to whether the maximum tumor dimension was above 5 cm or under 3 cm, the patients were divided into two groups. At the same time, we also divided the patients into two groups based on whether thoracotomy was performed. The data of both two groups were compared respectively. Results All surgeries were carried out safely with no serious complications or perioperative deaths. The average surgical duration was 185 minutes, and the average blood loss was 213 ml. Thirteen operations were converted to thoracotomy with a conversion rate of 7.6%. Among them, 9 were interfered by lymph nodes and bleeding happened in 4 operations. Lobectomy was performed on 12 patients and pneumonectomy was performed on 1 patient after thoracotomy. For the 16 cases of tumor with its dimension larger than 5 cm, the average operation time was 187 minutes and the average blood loss was 203.8 ml, while for the 98 cases of tumor with its dimension smaller than 3 cm, the average operation time was 202 minutes and the average blood loss was 231.3 ml. The difference between these two groups was not statistically significant. Among the 13 cases of conversion to thoracotomy, the mean age of the patients was 68.7 years old and the average tumor dimension was 23.8 mm. For the 159 cases without thoracotomy, the average age was 59.3 years old and the tumor dimension averaged 27.8 mm. There was a significant difference between them (P=0.016). Conclusion Interference by lymph nodes and bleeding are the most important causes of conversion to thoracotomy in completely thoracoscopic lobectomy while size of tumor, fused fissure or plural adhesions can be always managed thoracoscopically.
Objective To investigate the safety and efficacy of completely thoracoscopic lobectomy and the indications of this procedure. Methods Between Sep. 2006 and Jun. 2008, 100 consecutive patients（46 men，54 women, median age60.1±12.5 years，range from 18 to 82 years) underwent completely thoracoscopic lobectomy. All candidates were either peripheral pulmonary nodules suspected of lung cancer (85 pts.) or benign lesions (15 pts.) localized within single lobe who needed to receive lobectomy. The lobectomy was completed through three tiny incisions in the intercostal space. Anatomic lobectomies were carried out in all cases and systemic lymph node dissection was performed in malignancies. This group consisted of lobectomies of right upper lobe (n=25), right middle lobe (n=14), right lower lobe (n=22), left upper lobe (n=18), and left lower lobe (n=21). Results All procedures were successfully completed except for 3 conversions to thoracotomy. Postoperative diagnosis were primary lung cancer (n=81), lymphoma (n=1), metastasis of clear cell carcinoma from kidney (n=1), and, benign lesions (n=17). Five patients had mild complications in which two had atelectasis, one needed temperately echanical ventilation, one had pneumonia and one had chylothorax. All were treated conservatively without reoperation. No operative mortality or serious complications occurred in this group. The operative duration was 186.4±52.9min (range from 60 to 300 minutes). The blood loss was 233.9±275.9ml（range from 50 to 750ml）, and only one case needed blood transfusion. Chest drainage time was 7.1±3.0 days. Postoperative hospital stay was 9.5±3.2 days. Followedup time was for 1 to 27 months, metastasis happened in two patients with primary lung cancer 15 and 3 months separately after operation. Conclusion The completely thoracoscopic lobectomy is a safe and feasible surgical procedure with minimal invasiveness. The advocated indications include selected peripheral typed early stage lung cancer and benign pulmonary lesions which need lobectomy.
Objective To discuss the diagnostic value of multidetector CT(MDCT) on encapsulated fat necrosis after operation of abdominal cancer, and to investigate the key differences of CT features between encapsulated fat necrosis and postoperative recurrence or metastasis. Methods CT data of 36 patients with encapsulated fat necrosis after operation of abdominal cancer, who received CT in our hospital between Feb. 2012 to May. 2014 during followed-up were retrospectively analyzed, for the purpose of summarizing the CT characteristics. In addition, the clinical presentation, level of carcinoembryonic antigen (CEA) and CA-125 before and after operation were also taken into account, to explore the difference between encapsulated fat necrosis with tumor recurrence and metastasis. Results Among the 36 patients who had suffered from encapsulated fat necrosis after operation of abdominal cancer, 3 patients (8.3%) had 2 lesions and the rest of 33 patients (91.7%) had solitary lesion(a total of 39 lesions). All lesions showed non homogeneous masses consistent with the surgery path and surrounded by fat density ring and soft tissue density capsule. The size of most lesions (94.8%, 37/39) decreased over time. All lesions were found slightly enhancement in portal phase. Five patients with postoperative tumor metastasis, 31 patients had no recurrence or metastasis. Among the 5 patients who had postoperative tumor metastasis at the same time, postoperative CEA was positive in 3 patients, and postoperative CA-125 was positive in 2 patient. Among the other 31 patients who had no recurrence or metastasis, the levels of postoperative CEA and CA-125 of 1 patient were unknown, and the postoperative CEA and CA-125 of 27 patients in the rest patients(90.0%, 27/30) were both negative. Most of them had no special clinical symptoms, only a few (1 patient)patient had mild abdominal pain without other associated symptoms. Conclusion CT is a valuable tool to reveal and diagnose encapsulated fat necrosis in postoperative abdominal cancer. Combined CT findings(such as location, shape, and density) with CEA, CA-125, and clinical presentation, that is easy to differ it from postoperative recurrence and metastasis.
ObjectiveTo compare the short-term clinical outcomes of laparoscopic pancreaticoduodenectomy (LPD) with open pancreatoduodenectomy (OPD).MethodsClinical data of 29 patients receiving LPD and 27 patients receiving OPD in the department of hepatobiliary surgery of the Second Affiliated Hospital of Chongqing Medical University from March 2016 to December 2018 were collected. Note that both LPD and OPD were performed by the same chief surgeon. Effectiveness and safety of LPD were compared with those of OPD.ResultsThere was no significant difference in age, sex, body mass index, total bilirubin level, direct bilirubin level, preoperative morbidities, focus size, TNM stage and ASA grade between the LPD group and the OPD group (P>0.05). The operative time of the LPD group was significantly longer than that of the OPD group ［(482±86 ) min vs. (349±73) min, P<0.01］. Patients in the LPD group had shorter postoperative anal exhaust time than that in the OPD group ［(3.3±0.8) d vs. (5.3±1.0) d , P<0.05］. There was no significant difference in the length of hospital stay after operation, blood loss in operation, transfusion, second operation, death and postoperative complications between the LPD group and the OPD group (P>0.05).ConclusionsThe preliminary results of this study suggest that compared with OPD, LPD can shorten the postoperative anal exhaust time but not increase the incidence of postoperative complications and blood loss in operation. Nevertheless, this conclusion is needed to be validated by clinical studies with large sample size.
