Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.

Objective: To investigate the effect of remifentanil combined anesthesia on serum cytokines and oxidative stress indices in patients undergoing laparoscopic surgery for colon cancer

Study design: Experimental study

Place and duration of study: Department of anesthesiology, Yuhuangding Hospital affiliated to Qingdao University, Yantai, China, from may 2016 to march 2018

Methodology: A total of 154 patients undergoing laparoscopic surgery for colon cancer were randomly divided into control group and observation group, with 77 cases in each group. Control group received fentanyl combined anesthesia, and observation group received remifentanil combined anesthesia. Levels of serum cytokines IL-8, IL-6, CRP, TNF- alpha; and the levels of oxidative stress indices SOD, MDA, CAT, and GSH on the first day after operation were compared. Occurrence of adverse reactions during anesthesia recovery was observed and recorded in both groups

Results: On the first day after surgery, levels of serum cytokines IL-8, IL-6, CRP, TNF- alpha; and MDA in the observation group were lower than those in the control group [all p<0.001]; levels of serum SOD, GSH, and cat in the observation group were higher than those in the control group [all p<0.001]. The frequency of adverse reactions such as nausea and vomiting, chills, restlessness, cough, and tachycardia in the observation group was lower than that in the control group [p=0.029, 0.016, 0.009, 0.025, and 0.003, respectively]

Conclusion: Compared with fentanyl combined anesthesia, the remifentanil combined anesthesia can significantly reduce serum levels of cytokines IL-8, IL-6, CRP, TNF- alpha; and oxidative stress level, and is, therefore, more secure for patients undergoing laparoscopic surgery for colon cancer

Objective To discuss the key points of endovascular therapy for complex subclavian artery occlusive diseases. Methods During the period from January 2012 to December 2013, a total of 92 patients with complex subclavian artery occlusive disease were admitted to Xuanwu Hospital of Capital Medical University, Beijing, China. The clinical data were retrospectively analyzed. The features of the lesions, the success rate of endovascular therapy, the use of combined approaches, the relief of symptoms after treatment, etc. were evaluated. Results The complex subclavian artery occlusive diseases could be divided into three types. Type Ⅰ: long segment of the left subclavian artery was occluded; type Ⅱ: ostial stenosis or occlusion of the right subclavian artery; and type Ⅲ: subclavian artery stenosis or occlusion was associated with the ostial disorder of the vertebral artery, or the opening of vertebral artery was affected by the subclavian artery stenosis or occlusion. The technical success rate was 82.6%. Combination use of femoral artery and brachial artery approach was employed in 27.2% of patients, which had improved the technical success rate. After the treatment the symptom improvement rate was 81.6%. Conclusion Upper limb artery approach can improve the re-canalization rate of left subclavian artery with long segment occlusion, and can ensure the accurate positioning of stent at the site of right subclavian artery opening. During the procedure of endovascular intervention for subclavian artery occlusion disease, attention should be paid to the protection of the vertebral artery.

<p><b>BACKGROUND</b>Totally laparoscopic aortic surgery is still in its infancy in China. One of the factors preventing adoption of this technique is its steep learning curve. The objective of this study was to evaluate the feasibility and safety of laparoscopic surgery for aortoiliac occlusive disease (AIOD).</p><p><b>METHODS</b>From November 2008 to November 2012, 12 patients were treated for severe AIOD with a totally laparoscopic bypass surgery at our university hospital. The demographic data, operative data, postoperative recovery data, morbidity and mortality were analyzed and compared with those of conventional open approach.</p><p><b>RESULTS</b>Twelve totally laparoscopic aortic surgery procedures, including two iliofemoral bypasses (IFB), three unilateral aortofemoral bypasses (UAFB), and seven aortobifemoral bypasses (ABFB), were performed. Conversion to open procedures was required in three patients. The mean operation time was 518 (range, 325-840) minutes, mean blood loss was 962 (range, 400-2500) ml, and mean aortic anastomosis time was 75 (range, 40-150) minutes. Compared with conventional open approach for aortofemoral bypasses performed concomitantly during this period, laparoscopic patients required fewer narcotics and a shorter in-hospital stay and earlier recovery. Postoperative complications developed in four patients, including a single patient with transient left hydronephrosis, ischemic colonic fistula and pneumonia, residual aortic stenosis proximal to the anastomotic site, and asymptomatic partial left renal infarction. All patients recovered and were discharged on postoperative Days 7-14 except one patient that died of respiratory failure on Day 46. All grafts were patent with follow-up imaging performed by Duplex examination, with a mean follow-up time of 10.7 (range, 2-61) months.</p><p><b>CONCLUSION</b>Totally laparoscopic bypass surgery is a feasible and safe procedure for AIOD, but attention needs to be paid to improve laparoscopic skills of vascular surgery in order to minimize morbidity during the learning curve of this advanced procedure.</p>

<p><b>BACKGROUND</b>In-hospital medical complications are associated with poorer clinical outcomes for stroke patients after disease onset. However, few studies from China have reported the effect of these complications on the mortality of patients with acute ischemic stroke. In this prospective work, the China National Stroke Registry Study, we investigated the effect of medical complications on the case fatality of patients with acute ischemic stroke.</p><p><b>METHODS</b>From September 2007 to August 2008, we prospectively obtained the data of patients with acute stroke from 132 clinical centers in China. Medical complications, case fatality and other information recorded at baseline, during hospitalisation, and at 3, 6, and 12 months after stroke onset. Multivariable Logistic regression was performed to analyze the effect of medical complications on the case fatality of patients with acute ischemic stroke.</p><p><b>RESULTS</b>There were 39 741 patients screened, 14 526 patients with acute ischemic stroke recruited, and 11 560 ischemic stroke patients without missing data identified during the 12-month follow-up. Of the 11 560 ischemic patients, 15.8% (1826) had in-hospital medical complications. The most common complication was pneumonia (1373; 11.9% of patients), followed by urinary tract infection and gastrointestinal bleeding. In comparison with patients without complications, stroke patients with complications had a significantly higher risk of death during their hospitalization, and at 3, 6 and 12 months post-stroke. Having any one in-hospital medical complication was an independent risk factor for death in patients with acute ischemic stroke during hospital period (adjusted OR = 6.946; 95%CI 5.181 to 9.314), at 3 months (adjusted OR = 3.843; 95%CI 3.221 to 4.584), 6 months (adjusted OR = 3.492; 95%CI 2.970 to 4.106), and 12 months (adjusted OR = 3.511; 95%CI 3.021 to 4.080). Having multiple complications strongly increased the death risk of patients.</p><p><b>CONCLUSION</b>Short-term and long-term outcomes of acute stroke patients are affected by in-hospital medical complications.</p>

<p><b>BACKGROUND</b>Percutaneous transluminal renal angioplasty with stent is an effective procedure for atherosclerotic renal artery stenosis. However, the decision to perform this procedure has recently raised considerable debate. The aim of this study was to assess the effects of percutaneous transluminal renal angioplasty with stent in atherosclerotic renal artery stenosis patients, especially as it relates to blood pressure control and renal function improvement.</p><p><b>METHODS</b>A retrospective analysis was made of the clinical data from 125 atherosclerotic renal artery stenosis patients who underwent percutaneous transluminal renal angioplasty from July 2004 to June 2008 in the Department of Vascular Surgery of Beijing Chaoyang Hospital. We compared blood pressure, number of oral antihypertensive medications, and renal function changes pre and post-procedure at 24 months follow-up.</p><p><b>RESULTS</b>A total of 125 atherosclerotic renal artery stenosis patients underwent percutaneous transluminal renal angioplasty and 143 stents were placed. At 24 months follow-up, both systolic and diastolic blood pressure and the number of oral antihypertensive medications were significantly reduced (P < 0.05). Overall, the estimated glomerular filtration rate did not change significantly (P > 0.05); however, a significant increase in estimated glomerular filtration rate was observed in the subgroup of patients with a lower baseline estimated glomerular filtration rate and in the subgroup of patients with bilateral renal artery stenosis (P < 0.05).</p><p><b>CONCLUSION</b>Percutaneous transluminal renal angioplasty is a safe procedure for atherosclerotic renal artery stenosis patients, providing a significant improvement in blood pressure control and reduction in the number of oral antihypertensive medications.</p>

<p><b>OBJECTIVE</b>To observe the effect of parecoxib on morphine dosage in patient-controlled analgesia (PCA) following thoracoscope-assisted thoracotomy.</p><p><b>METHODS</b>A consecutive series of 100 patients undergoing thoracoscope-assisted thoracotomy were randomized into 5 groups and received PCA with morphine doses at 0, 5, 10, 15, and 20 mg given in 200 ml saline (groups P(1), P(2), P(3), P(4), and P(5), respectively). Parecoxib (40 mg) was given in all the patients immediately before the operation, and the mixture (4-5 ml) of lidocaine and ropivacaine was administered into the 3 intercostal spaces upper and lower to the incision before chest closure. PCA was administered for each patient. The visual analogue scale (VAS) at rest and coughing and the respiratory functional parameters were recorded at 1, 2, 4, 8, 12, 24, 36, and 48 h after the start of PCA, and the actual and effective button-pressing times (D(1)/D(2)) in PCA were also recorded.</p><p><b>RESULTS</b>No patients showed signs of respiratory inhibition within 24 h after the operation, and the resting VAS was comparable between the groups within the initial 6 postoperative hours. At 8 to 24 h postoperatively, the VAS scores at rest and coughing were significantly higher in P(1) group than in the other groups (P<0.05), and no significant differences were found between the groups at 36 to 48 h. D(1)/D(2) in groups P(1) and P(2) were significantly different from those in the other 3 groups at 4-24 h, but no such difference was found between groups P(3), P(4), and P(5).</p><p><b>CONCLUSION</b>The application of parecoxib may reduce the dosage of morphine in PCA following thoracoscope-assisted thoracotomy and results in good analgesic effect without affecting the patients respiratory function and sputum elimination.</p>

<p><b>OBJECTIVE</b>To explore the effect and mechanism of tagalsin on hepatoma cells.</p><p><b>METHODS</b>The animal models were established by transplanting H(22) mouse hepatoma cells to mouse liver, and ten days later the mice were randomly divided into five groups: blank group, carmofur positive group and tagalsin groups, including low-dose, middle-dose and high-dose groups. Then medicine or oil was given to the mice by gastric gavage in consecutive 5 days with a 2-days interval as a course of treatment, two courses in all. All mice were killed at 24 hours after medication, and the survival period, ascites conditions, aggressive conditions intra- or extra-liver, weight changes, tumor volume and spleen index of the tumor-bearing mice were observed. Pathological changes of the tumors were examined. Apoptotic factors p53 and Bcl-2 protien and mRNA were detected by immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>tagalsin inhibited the hepatoma growth effectively without influencing spleen index to some extent. The tumor inhibition rate of tagalsin low, middle and high dose groups were 17.9%, 63.1% and 71.8%, respectively. Immunohistochemical results showed that the p53 and Bcl-2 protein positive cell counts of the positive control and experimental groups were significantly lower than those of the blank group (P < 0.01). RT-PCR results showed that the p53 mRNA expression was significantly enhanced and Bcl-2 mRNA expression was decreased in the positive control groups and tagalsin treatment groups, especially in the high dose group, compared with those of the blank group (P < 0.05).</p><p><b>CONCLUSIONS</b>tagalsin can inhibit the growth of mouse hepatoma cells significantly. The mechanism of its anti-tumor effect may work via up-regulating the wild type p53 gene expression and down-regulating Bcl-2 gene expression and thus regulating tumor cell apoptosis.</p>

<p><b>BACKGROUND</b>Diagnosis and treatment for respiratory symptoms (RSs) of gastroesophageal reflux disease (GERD) is more difficult than that for common esophageal symptoms. The goal of this study was to evaluate the efficacy and safety of radiofrequency (RF) treatment on RSs of GERD in a preliminary 12-month follow-up observation.</p><p><b>METHODS</b>From April 2006 to October 2008, 505 GERD patients with mainly respiratory presentations such as wheezing, chronic cough or hoarseness, were treated by endoscopic RF. A questionnaire was completed before and after treatment, using a six-point scale ranging from 0 to 5 to assess symptom severity and frequency. The symptom score was the sum of frequency and severity.</p><p><b>RESULTS</b>Symptom scores were significantly improved at the end of the follow-up period. The mean heartburn score decreased from 5.31 to 1.79. The mean regurgitation score decreased from 5.02 to 1.64; mean cough score decreased from 6.77 to 2.85; mean wheezing score decreased from 7.83 to 3.07; and mean hoarseness score decreased from 5.13 to 1.81 (P < 0.01). No major complications or deaths occurred. Minor complications included temporary post-procedural retrosternal unease or pain (n = 106; 21.0%), mild fever (n = 86; 17.0%), transient nausea/vomiting (n = 97; 19.2%), and transient dysphagia (n = 42; 9.3%). Thirty-five (6.9%) patients had recurrence of symptoms. Endoscopic RF treatment was repeated in six patients, and laparoscopic fundoplication was performed in seven.</p><p><b>CONCLUSION</b>Endoscopic RF is an effective and safe means to treat RSs in patients with GERD.</p>

<p><b>BACKGROUND</b>Takayasu's arteritis (TA) is a chronic idiopathic inflammatory disease that affects large and medium size arteries. The brachiocephalic trunk is the most frequently involved site in TA, and multi-vessel lesions are common. Surgical treatment includes vessel reconstruction surgery and percutaneous transluminal angioplasty (PTA). Herein, we report our preliminary experience with surgical treatment of cerebral ischemia caused by cervical arterial lesions due to TA.</p><p><b>METHODS</b>From January 2000 to December 2007, 38 patients with cerebral ischemia caused by cervical arterial occlusive lesions due to TA were treated surgically. There were three males and 35 females, with an age range of 15 - 42 years (mean 26.5 years). All patients had operative repairs undertaken. Twenty eight patients received bypass operation and 10 patients received percutaneous transluminal angioplasty. One case with coronary stenosis received coronary artery bypass simultaneously. Patients were followed up for 11 months to eight years.</p><p><b>RESULTS</b>There were no peri-operative deaths in cerebrovascular reconstruction patients. Symptoms of cerebral ischemia were improved or cured in 25 of 38 patients. There was a low incidence of cerebral reperfusion syndrome. Two patients died at five and seven years after surgery due to heart failure. Another 8 patients (20%) required further surgery for stenosis (5 patients) or anastomotic aneurysms (3 patients). Percutaneous transluminal angioplasty was performed successfully for treatment of aortic and renal lesions. Repeated angioplasty for revascularization was performed in six PTA cases with restenosis after 5 - 24 months.</p><p><b>CONCLUSIONS</b>When cerebral perfusion has potential to be affected by TA, a definitive corrective procedure is advised when the patient is relatively stable. Although the recurrence rate is very high, percutaneous transluminal angioplasty is the first choice procedure. Bypass operation is optimal for brachiocephalic-vessel involvement in TA. Cerebral reperfusion syndrome can be avoided by careful selection of the operation method and improved post-operative treatment.</p>

<p><b>OBJECTIVE</b>To investigate the effects of microwave irradiation on the expression and regulation of heat shock proteins (HSPs) in primary cultured rat hippocampal neurons.</p><p><b>METHODS</b>Neurons were exposed to 90 mW/cm(2) microwave irradiation for 10 minutes. Western blot was used to determine the expression of HSP27, HSP70, HSP90 and heat shock factor 1 (HSF1) at 0, 3, 6, 12 and 24 hour respectively. Real-time RT-PCR was used to determine the mRNA expression of HSF1. DNA-binding activity of HSF1 was measured by electrophoretic mobility shift assay (EMSA).</p><p><b>RESULTS</b>The protein expression of HSP27 was significantly increased by 22%, 36%, 18% at 3, 6, 12 h, respectively (P < 0.05). The protein expression of HSP70 was significantly increased by 23%, 32%, 26% at 3, 6, 12 h, respectively (P < 0.05, P < 0.01). The protein expression of HSP90 was significantly increased by 27%, 33% at 6, 12 h, respectively (P < 0.05, P < 0.01). The DNA-binding activity of HSF1 was stimulated, however, no significant change of the expression of HSF1 was observed on both the mRNA and protein levels.</p><p><b>CONCLUSION</b>The transcriptional activity of HSF1 is activated by microwave irradiation, which promotes the expression of HSPs. Heat shock response which contributes to establish a cytoprotective state is induced by microwave irradiation in primary cultured rat hippocampal neurons.</p>

<p><b>OBJECTIVE</b>To evaluate medium-long term patency of below-knee bypass on patients who suffered from diabetic lower limb ischemia.</p><p><b>METHODS</b>Clinical and follow-up data of 51 patients was retrospectively analyzed who underwent 56 below-knee bypass because of diabetes from November 2001 to December 2006. There were 35 male and 16 female with an average age of 68 years. They endured 26 months ischemic time lag in average, and had suffered from diabetes for 11 years. All of the patients were performed bypass to below-knee (posterior tibial, anterior tibial or peroneal) arteries. Kaplan-meier method was applied. The subgroups of different operative methods and different out-flow vessels were compared by Log-rank tests.</p><p><b>RESULTS</b>An average follow-up time of 23 months was achieved, and lost-follow-up rate was 15%. The total 1- and 5-year primary patent rates were 68% and 54% respectively, secondary patent rate were 70% and 60% respectively, limb salvage rates were 69% and 65%, survival rates were 82% and 60%. One year (3 years) of patent rate(s) of operative method subgroups of femoral-popliteal-infrageniculate bypass with composite grafts, femoral/popliteal-infrageniculate bypass with artificial grafts and femoral/popliteal-infrageniculate bypass with autologous veins were 70% (50%), 33% (33%) and 70% (70%) respectively. One year (4 years) of patent rate(s) of out-flow vessel subgroups of posterior tibial artery, anterior tibial artery and peroneal artery were 65% (60%), 80% (53%) and 77% (66%) respectively. However, both subgroups did not show any statistic differences by log-rank tests.</p><p><b>CONCLUSIONS</b>Partial or whole autologous veins as bypass grafts should be chosen when infrageniculate bypass is considered in diabetic patients. Considerable patent rates are acceptable no matter what kinds of out-flow vessels are chosen.</p>
