OBJECTIVETo summarize the perioperative and postoperative complications follow laparoscopic intersphincteric resection (LapISR) in the treatment of low rectal cancer and their management.
METHODSAn observational study was conducted in 73 consecutive patients who underwent LapISR for low rectal cancer between June 2011 and February 2016 in our hospital. The clinicopathological parameters, perioperative and postoperative complications, and clinical outcomes were collected from a prospectively maintained database. Perioperative and postoperative complications were defined as any complication occurring within or more than 3 months after the primary operation, respectively.
RESULTSForty-nine(67.1%) cases were male and 24(32.9%) were female with a median age of 61(25 to 79) years. The median distance from distal tumor margin to anal verge was 4.0(1.0 to 5.5) cm. The median operative time was 195 (120 to 360) min, median intra operative blood loss was 100 (20 to 300) ml, median number of harvested lymph nodes was 14(3 to 31) per case. All the patients underwent preventive terminal ileum loop stoma. No conversion or hospital mortality was presented. The R0 resection rate was 98.6% with totally negative distal resection margin. A total of 34 complication episodes were recorded in 21(28.8%) patients during perioperative period, and among which 20.6%(7/34) was grade III(-IIII( according to Dindo system. Anastomosis-associated morbidity (16.4%,12/73) was the most common after LapISR, including mucosa ischemia in 9 cases(12.3%), stricture in 7 cases (9.6%, 4 cases secondary to mucosa necrosis receiving anal dilation), grade A fistula in 3 cases (4.1%) receiving conservative treatment and necrosis in 1 case (1.4%) receiving permanent stoma. After a median follow up of 21(3 to 60) months, postoperative complications were recorded in 12 patients (16.4%) with 16 episodes, including anastomotic stenosis (8.2%), rectum segmental stricture (5.5%), ileus (2.7%), partial anastomotic dehiscence (1.4%), anastomotic fistula (1.4%), rectovaginal fistula (1.4%) and mucosal prolapse (1.4%). These patients received corresponding treatments, such as endoscopic transanal resection, anal dilation, enema, purgative, permanent stoma, etc. according to the lesions. Six patients (8.2%) required re-operation intervention due to postoperative complications.
CONCLUSIONAnastomosis-associated morbidity is the most common after LapISR in the treatment of low rectal cancer in perioperative and postoperative periods, which must be strictly managed with suitable methods.

Duodenal injury is a serious abdominal organ injury. Duodenal fistula is one of the most serious complications in gastrointestinal surgery, which is concerned for its critical status, difficulty in treatment and high mortality. Thoracic and abdominal compound closed injury and a small part of open injury are common causes of duodenal injury. Iatrogenic or traumatic injury, malnutrition, cancer, tuberculosis, Crohn's disease etc. are common causes of duodenal fistula, however, there has been still lacking of ideal diagnosis and treatment by now. The primary treatment strategy of duodenal fistula is to determine the cause of disease and its key point is prevention, including perioperative parenteral and enteral nutrition support, improvement of hypoproteinemia actively, avoidance of stump ischemia by excessive separate duodenum intraoperatively, performance of appropriate duodenum stump suture to ensure the stump blood supply, and avoidance of postoperative input loop obstruction, postoperative stump bleeding or hematoma etc. Once duodenal fistula occurs, a simple and reasonable operation can be selected and performed after fluid prohibition, parenteral and enteral nutrition, acid suppression, enzyme inhibition, anti-infective treatment and maintaining water salt electrolyte and acid-base balance. Double tube method, duodenal decompression and peritoneal drainage can reduce duodenal fistula-related complications, and then reduce the mortality, which can save the lives of patients.

To discuss the protective effect of aralosides (AS) on I/R-induced rat myocardial injury. The adult rat ventricular myocyte ischemia model was established through perfusion with sodium lactate perfusate and reperfusion with Ca(2+) -containing Tyrode's solution simulation. The cell contraction and ion concentration synchronization determination system was applied to detect the effect of AS on single I/R cell contraction and Ca2+ transients. According to the findings, AS could increase resting sarcomere length, contraction amplitude, ± dL/dt(max), calcium transient amplitude and speed of post-reperfusion myocardial cells (P < 0.05, P < 0.01), and decrease in time for achieving 90.0% of maximum relaxation, time for achieving peak value, resting calcium ratio, contraction period [Ca2+] i, time for achieving 50.0% of maximum relaxation and attenuation rate of intracellular calcium transient (P < 0.05, P < 0.01). Therefore, it is suggested that AS improved the post-reperfusion cell contraction and injury of calcium homeostasis.

To observe the protective effect and mechanism of Sailuotong capsule in focal cerebral ischemia/reperfusion. The 90 min middle cerebral artery occlusion (MCAO) reperfusion model was established. The expressions of dynamin-related protein 1 ( Drp1) and optic atrophy 1 (Opa1) were tested by Western blot. The transmission electron microscope was used to observe the changes in the mitochondrial ultra-structure. The pathological morphological changes were observed through the HE staining. The immunohistochemical method was used to test Drp1 and Opa1 expressions. Sailuotong capsule (33, 16.5 mg x kg(-1), ig) can inhibit the abnormal mitochondrial fission and fusion in the cortical area on the ischemia side and the mitochondrial fission gene expression and promote the mitochondrial fusion gene Opa1 expression, so as to alleviate the energy metabolism disorder caused by ischemia/reperfusion. Sailuotong capsule can inhibit the abnormal mitochondrial dynamics in peri-ischemic regions and maintain the normal morphology of mitochondria, which may be the mechanism of Sailuotong capsule in promoting the self-recovery function in the ischemic brain region.

OBJECTIVETo analyze the trends in treatments of lower extremity peripheral arterial disease and their prognosis in the recent 10 years.
METHODSClinical data of inpatients with lower extremity peripheral arterial disease who received surgical treatments in Xuanwu Hospital from January 2002 to December 2011 were analyzed retrospectively. Patients were stratified into two groups (group 1: from 2002 to 2006, group 2: from 2007 to 2011). The demographics, risk factors, clinical presentation, lesion anatomy, therapies, limb salvage and survival were observed. χ(2) test, Fisher exact test, and t test were used to compare the data between the two groups.
RESULTSFrom 2002 to 2006, 170 limbs (47.49%) underwent conventional bypass surgery, 72 limbs (20.11%) underwent endovascular interventions and the rest 116 limbs (32.40%) received stem cell treatment. While from 2007 to 2011, the percentages were 18.49%, 68.73%, 8.27%, respectively. Furthermore, gene-based drug appeared, 67 limbs (4.51%) underwent the new treatment. Former group had decreased limb salvage rates compared with latter group (87.15% vs. 93.41%, χ(2)=15.71, P=0.000). However, survival rates did not differ from the two groups (84.67% vs. 84.31%, χ(2)=0.02, P=0.880).
CONCLUSIONWith the appearance of new medical instruments and operating methods, the percentage of the patients with lower extremity peripheral arterial disease receive endovascular interventions increases, with a improved limb salvage rates.

6.Research progress of acupuncture for cerebral ischemia reperfusion injury in recent 10 years.
Chinese Acupuncture & Moxibustion 2015;35(7):749-752
By searching relevant data from the PubMed database, Chinese National Knowledge Infrastructure (CNKI) database and Wanfang database, a comprehensive analysis and review regarding acupuncture for cerebral ischemia reperfusion injury (CIRI) in recent 10 years were performed. The results showed that acupuncture could inhibit the inflammatory reaction, reduce oxidative stress injury, restrain brain edema formation, inhibit apoptosis, promote neural and vascular regeneration, etc. Acupuncture methods used included electroacupuncture, scalp acupuncture, eye acupuncture and "consciousness-restoring resuscitation needling", etc. The existing problem was that the intervention action of acupuncture was mainly focused on inhibiting inflammatory reaction and oxidative stress injury, and the study on apoptosis and neural and vascular regeneration was needed. It is suggested that from the aspect of multiple target points, the intervention mechanism of acupuncture for CIRI should be systemically studied in the future, which could provide new idea for clinical diagnosis and treatment on ischemic cerebrovascular diseases.

8.Clinical Application of Adipose Stem Cells in Plastic Surgery.
Journal of Korean Medical Science 2014;29(4):462-467
Adipose stem cells (ASCs) are a type of adult stem cells that share common characteristics with typical mesenchymal stem cells. In the last decade, ASCs have been shown to be a useful cell resource for tissue regeneration. The major role of regenerative medicine in this century is based on cell therapy in which ASCs hold a key position. Active research on this new type of adult stem cell has been ongoing and these cells now have several clinical applications, including fat grafting, overcoming wound healing difficulties, recovery from local tissue ischemia, and scar remodeling. The application of cultured cells will increase the efficiency of cell therapy. However, the use of cultured stem cells is strictly controlled by government regulation to ensure patient safety. Government regulation is a factor that can limit more versatile clinical application of ASCs. In this review, current clinical applications of ASCs in plastic surgery are introduced. Future stem cell applications in clinical field including culturing and banking of ASCs are also discussed in this review.

The purpose of this study was to determine the combined effect of transmyocardial laser revascularization (TMLR) and the implantation of endothelial progenitor cells (EPCs) on cardiac function of ischemic hearts in canines. The left anterior descending artery (LAD) was occluded to establish the canine model of acute myocardial infarct (AMI). Four weeks later, the animals were randomly divided into four groups: TMLR group, in which transmyocardial laser-induced channels were established at the ischemic region; EPCs+TMLR group, in which EPCs were locally transplanted into laser-induced channels at the ischemic region; EPCs group, in which the EPCs were injected into the ischemic region; control group, in which the AMI animals received neither TMLR nor EPCs. The peripheral blood (50 mL) was sampled in all groups. Mononuclear cells from the peripheral blood were separated and cultured to obtain spindle-shaped attaching (AT) cells in vitro. AT cells were labeled with 1, 1'-dioctadecyl-1 to 3,3, 3',3'-tetramethyl-indocarbocyanine perchlorate (DiI) before injecting into the laser-induced channels or ischemic region. Four weeks after the first operation, TMLR was performed in the TMLR group and EPCs+TMLR group, and at the same time, the EPCs originating from the AT cells were mixed with calcium alginate (CA). Then the EPCs-CA composites were implanted into myocardial channels induced by laser in the EPCs+TMLR group, and into the myocardial infarct area in the EPCs group. All dogs underwent echocardiography at second month after LAD occlusion. Finally the samples of myocardium around the LAD were subjected to histochemical and immunohistologic examinations. The results showed there was no significant difference in the diameter of left atrium and ventricle before treatment among all groups (P>0.05). Eight weeks after modeling, the regional contractility in the LAD territory in the EPCs+TMLR group was increased as compared with control group and TMLR group, but there was no significant difference between control group and TMLR group. Neoangiogenesis was observed in the EPCs+TMLR group, and the fibrosis was seen in the TMLR group. There was no significant difference in neoangiogenesis around the channels induced by laser among EPCs+TMLR, EPCs and TMLR groups. It was concluded that TMLR combined with EPCs could improve the regional and global cardiac function in AMI, and augment neovascularizaiton in channels of ischemic myocardium induced by laser.

OBJECTIVETo explore the effects and action mechanism of electroacupuncture (EA) pretreatment on rats with transient cerebral ischemia/reperfusion.
METHODSA total of 144 healthy SD male rats were randomly divided into a sham operation group (group S), an ischemia/reperfusion group (group I/R) and an EA pretreatment group (group EA), 48 rats in each one. The model of cerebral ischemia/reperfusion was established by using 4-vessel occlusion method in the group I/R; after 5 min of cerebral ischemia, the reperfusion was performed. The group EA was treated with EA at "Dazhui" (GV 14) and "Baihui" (GV 20) 5 days before model establishment, 30 min per time, once a day. In group S, bilateral foramen alares were exposed without burning on the vertebral arteries, and bilateral common carotid arteries were unfolded and not occluded. The rats in the group I/R and group EA were sacrificed 6 h, 12 h, 24 h and 48 h after reperfusion and those in the group S were sacrificed at corresponding time to collect hippocampus example. The Western-blot method was used to measure the expression of glucose-regulated protein 78 (GRP 78), and HE staining method was used to count the number of surviving neurons, and TUNEL method was used to measure the number of apoptotic neurons.
RESULTSCompare with the group S, the number of surviving neurons in hippocampus was reduced at each reperfusion time point and the number of apoptotic neurons was increased (all P<0.05) in the group I/R and the group EA; the expression of GRP 78 at each reperfusion time point in group I/R and group EA was increased (P<0.05). Compared with the group I/R, the number of surviving neurons in hippocampus was increased at each reperfusion time point and the number of apoptotic neurons was reduced in the group EA (P<0.05); the expression of GRP 78 at each reperfusion time point was further increased (P<0.05).
CONCLUSIONThe electroacupuncture pretreatment has obvious cerebral protection on rats with ischemia/reperfusion, which is related with further increasing the expression of GRP 78 in ischemia area, leading to relieved endoplasmic reticulum stress.
