Abstract
Objective: To examine the safety and feasibility of using fusion indocyanine green fluorescence imaging (FIGFI) technique for intraoperative evaluation of colorectal perfusion in the totally laparoscopic left colectomy. Methods: A retrospective cohort study was conducted to collect the clinical data of 58 patients with left colon cancer who underwent totally laparoscopic surgery at the Colorectal Surgery Department, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to December 2019. There were 39 males and 19 females, aging (57.0±10.1)years(range:28 to 75 years). According to whether the FIGFI was used during the operation, they were divided into 36 cases in the study group and 22 cases in the control group. The clinical pathological characteristics, operative and postoperative recovery of the two groups were compared by t test, χ2 test, and Fisher exact test. Results: All the 58 patients underwent R0 resection with totally laparoscopic surgery. In the study group, due to poor bowel blood flow after cutting the mesentery (Sherwinter score = 1), 1 patient had to be expanded the resection range until the blood flow was rich(Sherwinter score≥3), and 1 patient in the control group had the complication of postoperative anastomotic leakage of grade A. Compared with the control group, the operation time in the study group was shorter ((156.3±43.5) minutes vs. (180.4±41.3) minutes, t=-2.083, P=0.042). However, there were no significant differences in the amount of blood loss, postoperative hospital stay, postoperative time of anal exhaust, length of bowel resection, number of lymph nodes dissected, and in the incidence of postoperative complications between the two groups. Median follow-up period was 23 months (range: 18 to 37 months). There were no long-term postoperative complications such as ischemic enteritis and anastomotic stenosis in both groups. Conclusions: The FIGFI is safe and feasible to assess the blood supply of intestinal segment and anastomosis during totally laparoscopic left hemicolectomy, and is easy to operate. It is expected to reduce the incidence of anastomotic leakage.

Abstract
Objective: To explore the value of night pulse oximetry monitoring in the prediction and classification of obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: From January 2018 to December 2019, 580 snoring patients admitted to the Sleep Center of Tianjin Medical University General Hospital were analyzed retrospectively. There were 418 males and 162 females, aging 13-85(49±14) years. All subjects underwent polysomnography, and the apnea hypopnea index (AHI)was 0-101.4(43.06±27.47) times/hour. There were 52 cases in the non-OSAHS group (AHI<5 times/h), 69 cases in the mild OSAHS group (5 times/h<AHI≤15 times/h), 98 cases in the moderate OSAHS group (15 times/h<AHI≤30 times/h), and 361 cases in the severe OSAHS group (30 times/h<AHI).Correlation analysis was performed between indicators extracted from SpO2 signal and AHI, and 11 blood oxygen indicators related to AHI were selected (3% oxygen reduction recovery index, the area of SpO2 under the 90% curve, average lowest SpO2, lowest SpO2, the average SpO2, the percentage of time SpO2 under 95%, 90%, 85%, 80%, 75%, 70%). Finally, gender, age and body mass index (BMI) were added. We ysed multiple linear regression (MLR) method to achieve AHI prediction, and back propagation neural network (BPNN) multi-classification method to achieve OSAHS severity classification. Statistical analysis was performed based on SPSS 25.0. The measurement data were analyzed using Pearson correlation test. Results: The MLR method achieved high prediction performance, with a prediction correlation coefficient r=0.901 (P<0.05) and a goodness of fit r2 = 0.848 (P<0.05).The specificity and negative prediction rate of BPNN method classification results were both around 90%, and the sensitivity and positive prediction rates were also high. Among them, the sensitivity of the non-OSAHS group (AHI<5 times/h) was 88.46%±4.50%, and the sensitivity of the severe OSAHS group (AHI>30 times/h) was 94.74%±0.76%. Conclusion: Based on the signals recorded by the SpO2 monitor, the methods of using MLR model for AHI prediction and using BPNN model for multi-classification may have higher value for the prediction and classification of OSAHS.

Abstract
Atherosclerosis is a chronic inflammatory vascular disease. Atherosclerotic cardiovascular disease is the main cause of death in both developed and developing countries. Many pathophysiological factors, including abnormal cholesterol metabolism, vascular inflammatory response, endothelial dysfunction and vascular smooth muscle cell proliferation and apoptosis, contribute to the development of atherosclerosis and the molecular mechanisms underlying the development of atherosclerosis are not fully understood. Ubiquitination is a multistep post-translational protein modification that participates in many important cellular processes. Emerging evidence suggests that ubiquitination plays important roles in the pathogenesis of atherosclerosis in many ways, including regulation of vascular inflammation, endothelial cell and vascular smooth muscle cell function, lipid metabolism and atherosclerotic plaque stability. This review summarizes important contributions of various E3 ligases to the development of atherosclerosis. Targeting ubiquitin E3 ligases may provide a novel strategy for the prevention of the progression of atherosclerosis.

Abstract
Research of in-situ induced repair and regeneration is a multi- and inter-disciplinary field, which is of important potentials in the treatment of both large-area deep burns and chronic wounds such as diabetic skin ulcers. In-situ forming injectable hydrogels which are hydrogel-like biomaterials that can spontaneously gelatinize in physiological condition when applied in local wounds have been explored in recent years. This kind of biomaterials contain extracellular matrix, in which cells promoting wound repairing can be added if required, and can work as release-controlled carriers for active peptides such as growth factors to simulate local wound microenvironment and induce the repair and regeneration. Herein, characteristics and function of promoting wound repair and regeneration about in-situ forming injectable hydrogels were reviewed, including material types and their relevant working mechanisms, advantages, existing problems, etc.

Abstract
Objective: To analyze the clinical characteristics of infantile Takayasu arteritis and the efficacy of infliximab (IFX). Methods: Clinical manifestations, laboratory investigations and infliximab intervention of a case with infantile Takayasu arteritis, who was admitted to Department of Rheumatism and Immunology, Children's Hospital, Capital Institute of Pediatrics in January 2018, were reviewed and analyzed. The related literature published from the beginning to March 2020 were retrieved from CNKI, Wanfang, SinoMed and PubMed with the keywords of"Takayasu arteritis","Infant" in both Chinese and English. Results: This case was a 70-day-old boy admitted due to recurrent fever for 20 days. On admission, his blood pressure were 104/90, 95/59, 125/80, and 152/125 mmHg (1 mmHg=0.133 kPa) in the right arm, left arm, right leg, and left leg, respectively. The complete blood cell count showed leukocytosis (22.6×109/L), thrombocytosis (858×109/L) and mild anemia (80 g/L). He also had elevated erythrocyte sedimentation rate (119 mm/1h), serum ferritin (598 μg/L) and C-reactive protein (112 mg/L). Computed tomographic angiography (CTA) showed narrowing of the thoracic and abdominal aorta, with thickening and heterogenous enhancement of the vessel wall. Coronary artery ultrasound detected dilatation and wall thickening of the bilateral coronary arteries, and uneven dilatation of the middle segment of the right coronary artery, showing bead-like change. Vessel wall thickening was also found in the other main arteries, including both femoral arteries, axillary arteries, carotid arteries, and subclavian arteries, and both superficial femoral arteries were slightly narrowed in the distal segments. The diagnosis of TA was confirmed, and the boy was treated with infliximab monotherapy (5 mg/(kg·every time), a total of 13 times). Then his body temperature and all inflammatory markers were normalized, and the vascular pathology was resolved according to the radiography. No side effects such as allergy or infection were noted during the treatment. During the 2 years and 6 months of follow-up, the boy maintained normal growth and development. Literature review found 8 related articles, and one of them was in Chinese but had limited information. In the other 7 papers, a total of 7 infants with TA were reported. The most common symptom was fever (5 cases), and inflammatory markers usually elevated, and the most common affected artery was abdominal aorta (6 cases). Most cases were treated with glucocorticoid. Conclusions: TA is a rare disease in infants, usually presents with fever and increased inflammatory markers. At the early stage, infliximab monotherapy could effectively control the symptoms and ensure normal growth and development.

Abstract
Objective: In laparoscopic-assisted left hemicolectomy, previous studies have suggested that preserving the inferior mesenteric artery (IMA) may improve intestinal blood flow and reduce the incidence of anastomotic leakage. However, whether IMA should be retained is controversial currently. This study aims to investigate the short-term efficacy of the inferior mesenteric artery preservation (IMAP) and the inferior mesenteric artery resection (IMAR) on the laparoscopic-assisted radical resection of left hemicolon cancer. Methods: A retrospective cohort study was conducted to collect the clinical data of 195 patients with left colon cancer who underwent laparoscopic surgery in the Colorectal Surgery Department of Cancer Hospital of Chinese Academy of Medical Sciences from October 2012 to February 2019. After D3 radical resection for left semicolon cancer, they were divided into the IMAR group (91 cases), and the IMAP group (104 cases). In IMAR group, the left colon artery (LCA) and 1-2 branches of sigmoid artery (SA) were identified about 5 cm away from the root of the IMA, then the main IMA trunk was transected at the distal end. In IMAP group, the main trunk of IMA was dissected and the lymph nodes around IMA were cleaned. After the LCA and the first branch of SA (SA1) were separated, the LCA and SA1 were closed and cut off at the root. The intraoperative and postoperative data were compared between two groups, including the morbidity of complications within 30 days after operation, postoperative follow-up recovery, operation time, intraoperative blood loss, number of harvested lymph nodes, length of specimens, postoperative passage of gas and hospital stay. Results: The operation was successfully completed in all the cases without any death related to the operation. Compared with the IMAP group, the operation time was shorter [(161.8±48.0) minutes vs. (182.9±49.4) minutes, t=2.985, P=0.003], the intraoperative blood loss was less [(38.5±30.8) ml vs.(52.9±32.2) ml, t=2.088, P=0.038], the length of the resected bowel was longer [(19.2±6.0) cm vs.(17.2±5.4) cm, t=-2.447, P=0.015] in the IMAR group, whose differences were statistically significant (all P<0.05). There were no significant differences in the number of harvested lymph nodes, time of postoperative passage of gas and postoperative hospital stay between two groups (all P>0.05). There was no significant difference in overall morbidity of postoperative complications between the two group [6/91 (6.6%) vs. 7/104 (6.7%), χ(2)=0.001, P=0.969]. In the IMAR group, one case developed postoperative abdominal infection, two cases developed incision infection, one case developed lung infection, two cases developed intestinal obstruction, and no anastomotic bleeding occurred. In IMAP group, one case developed postoperative lung infection, one case developed incision infection, one case developed abdominal bleeding, two cases developed intestinal obstruction and two cases developed anastomotic bleeding. There was no anastomotic leakage in either group. All complications were treated by conservative treatment successfully. After a median follow-up of 12 (range 3-24) months, patients in the two groups had good intestinal blood supply after surgery, and there was no clear manifestation of congestive or ischemic enteritis under colonoscopy. Conclusion: Laparoscopic-assisted left hemicolectomy with IMA resection in patients with left hemicolon cancer provides better short-term efficacy safely and feasibly, including shorter operative time, less intraoperative bleeding and without increasing postoperative complications.

Abstract
BACKGROUND AND PURPOSE Comprehensive geriatric assessment (CGA) is a diagnostic method to assess the physical and mental health status of older patients. The purpose of this study was to assess the safety and efficacy of preoperative concurrent chemoradiotherapy (preCRT) for intermediate or locally advanced rectal cancer in older people who were classified as "fit" by CGA. The interim analysis focusing on safety was reported here as the first part of this trial. METHODS AND MATERIALS This is a single arm, multicenter, phase II trial. The eligible patients for this study were aged 70 years or above that fulfilled the standard of intermediate or locally advanced risk category, and met the standard of fit (SIOG1) evaluated by CGA. All patients received preCRT (50 Gy) with Raltitrexed (3 mg/m2 on d1 and d22). Qualitative and quantitative variables were described using descriptive statistics. The surgery adherence predicting was analyzed by multivariate logistic regression. RESULTS Thirty-nine fit patients were enrolled. All patients except one finished radiotherapy without dose reduction. Thirty-two patients finished the prescribed Raltitrexed therapy as scheduled. A serious toxicity was observed in 12 patients (30.8%), and only six patients (15.4%) experienced non-hematological side effects. CONCLUSION Overall, our results showed that preCRT was feasible and safe in older patients with rectal cancer who were evaluated as fit based on CGA, supporting the use of CGA to tailor oncological treatment and predict the tolerance of a specific therapy. Completing this trial as planned would provide further valuable insights.

Abstract
The derived feathering phenotype beard in domestic birds is an ideal resource to investigate the genetic mechanisms controlling feather development and differentiation. In the present study, we performed a GWAS and QTL linkage analysis on the trait of beard in Beijing fatty chicken. One major QTL (1.2-1.9 Mb) was identified that could explain 34% of the phenotypic variation. The copy number variation that was copied from the region (GGA27:3 578 409-3 592 890 bp) containing homebox B7 (HOXB7) and homebox B8 (HOXB8) was validated to be only exhibited in the genome of bearded chickens. Protein-protein interaction analysis indicated that HOXB7 and HOXB8 proteins could highly interact with the HOXB family members, including HOXB4, HOXB5 and HOXB6, whose genomic locations near HOXB7 and HOXB8 suggested that they may regulate their family members to involve in the formation of the beard trait in chickens. Overall, our work provides basic data for understanding the mechanisms regulating beard development and differentiation.

Abstract
Objective: To investigate the risk factors of severe postoperative complications in elderly patients with colorectal cancer aged over 80 years old. Methods: A retrospective case-control study was conducted to collect and analyze the clinicopathological data of patients (≥80 years old) who underwent radical colorectal cancer surgery at department of Colorectal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from January 2010 to December 2018. A total of 269 patients were included in the study, including 160 males and 109 females. The average age was 83 (80-94) years. Among them, the pathological TNM stage was 16 in stage I, 76 in stage II, 167 in stage III, and 10 in stage IV. According to Clavien-Dindo classification, the postoperative complications of grade III and above were defined as serious complications. To analyze the relationship between the patient's clinical data, such as general information, the surgeon's experience (whether to complete more than 500 radical colorectal cancer surgery), intraoperative conditions and the occurrence of severe complications. Univariate analysis was conducted with the chi-squared test. Multivariate logistic regression analysis was used for statistically significant variables in univariate analysis. Results: Of the 269 patients, 34 (12.6%) had severe complications after surgery. The incidence of postoperative complications ranged from high to low, respectively, for pulmonary infection (8/269,3.0%), intestinal obstruction (8/269, 3.0%) and anastomotic leakage (7/269, 2.6%). One patient died of pulmonary embolism and one patient died of multiple organ failure, with a perioperative mortality rate of 0.7% (2/269). On univariate analysis, the occurrence of severe postoperative complications was associated with age (χ(2)=8.181, P=0.004), American society of anesthesiologists grade (χ(2)=7.945, P=0.005), preoperative albumin level (χ(2)=9.088, P=0.003), operation experience (χ(2)=9.395, P=0.002). Multivariable logistic regression analysis showed that age ≥85 years old (OR=4.415, 95% CI: 1.702-11.453, P=0.080), preoperative albumin <35 g/L (OR=2.544, 95%CI: 1.083-5.974, P=0.032), and less-experieced group (OR=2.475, 95% CI:1.082-5.661, P=0.032) was independent risk factor for severe postoperative complications. The incidence of serious postoperative complications was similar in patients undergoing laparoscopy and laparotomy [10.1% (17/169) vs. 17.0% (17/100), χ(2)=2.741, P=0.098]. Conclusion: Adequate preoperative evaluation, appropriate perioperative nutritional support and experienced specialists are the key factors to ensure the successful perioperative period of elderly patients with colorectal cancer aged over 80 years old. In addition, more attention should be paid to the elderly patients aged ≥85 years.

Abstract
Objective: To evaluate the safety, feasibility and short-term efficacy of totally laparoscopic left colectomy for left colon cancer by using overlapped delta-shaped anastomosis technique for digestive tract reconstruction. Methods: A retrospective cohort study was conducted to collect the clinical data of 86 patients with left colon cancer who underwent laparoscopic surgery in Cancer Hospital of Chinese Academy of Medical Sciences from October, 2017 to February, 2019. The patients were divided into totally laparoscopic left-sided colectomy (TLLC) (treatment group, n=25 cases) and laparoscopic-assisted left-sided colectomy (LALC) (control group, n=61 cases). The intraoperative and postoperative data were compared between the two groups. Results: There were no surgical-related deaths in both groups. All the patients in the TLLC group underwent laparoscopic resection, while one patient in the LALC group transfer to open surgery. The operation time in TLLC group and LALC group were (164.5±42.3) min and (171.0±43.1) min, respectively, without statistically significant difference (P=0.516). However, the intraoperative blood loss of patients in the TLLC group was (36.4±22.7) ml, which was significantly less than (52.9±32.2) ml in the LALC group (P=0.026). The anastomosis time in the TLLC group was (39.1±6.5) min, which was significantly longer than (24.9±5.4) min in the LALC group (P<0.001). Postoperative exhaust time in the TLLC group was (2.6±0.5) days, which was significantly shorter than (3.3±0.8) days in the LALC group (P<0.001). The incision length in the TLLC group was (4.2±2.2) cm, significantly shorter than (7.0±2.5) cm in the LALC group (P<0.001). The length of the resected bowel was (21.0±7.3) cm in the TLLC group, which was significantly longer than (17.5±5.4) cm in the LALC group (P=0.037). The length of hospital stay in the TLLC group was (6.2±1.9) days, which was significantly shorter than (7.9±1.5) days in the LALC group (P<0.001). The incidences of postoperative complications in the TLLC group and LALC group were 0 and 4.9% (3/61), respectively, without statistically significant (P=0.553). No anastomotic complications occurred in both groups. During the follow-up period, neither group of patients was hospitalized again, and no tumor metastasis or recurrence occurred. Conclusions: It is safe and feasible to apply the TLLC with overlapped delta-shaped anastomosis in patients with left colon cancer. It has better short-term effects such as shorter incisions, faster recovery, and shorter postoperative hospital stays, and is worthy of further promotion.

Abstract
Caged layer osteoporosis (CLO) is a common bone metabolism diseases and poses a great threat to the production of laying hens. So far, there is no effective nutrition intervention to prevent CLO. The objective of this study was to evaluate the effects of dietary total flavonoids from Rhizoma Drynariae (TFRD), a Chinese herbal, on bone health, egg quality, and serum antioxidant capacity of caged laying hens. A total of two hundred sixteen, 54-wk-old Lohmann Pink-shell laying hens at were allocated to 3 groups with 6 replicates of 12 hens per replicate. The control group was fed a basal diet (BD) and 2 treatment groups additionally supplied with 0.5 or 2.0 g/kg TFRD, respectively. Results showed that supplying 2.0 g/kg TFRD enhanced the activities of serum total antioxidant capacity (P < 0.01) and glutathione peroxidase (P < 0.05) and had higher femur and tibia bone mineral density (both P < 0.05) compared with the control group. Dietary 2.0 g/kg TFRD also reduced the activities of serum alkaline phosphatase (P < 0.01), tartrate resistant acid phosphatase (P < 0.01), and the contents of osteocalcin (P < 0.01). Furthermore, tibia histomorphology observation showed that the microstructure of bone tissue was improved after TFRD treatment. Egg quality was not affected by TFRD while the egg weight significantly increased (P < 0.01). These findings suggested that TFRD has beneficial effects on bone health in older caged laying hens.

Abstract
AIM AND OBJECTIVE Phenazines are substances with an extensive range of important applications. Recently, the synthesis of N-arylation has been made more feasible owing to the advent of a new methodology. But because the toxicity of the used oxidant and the low yield, it is necessary to find a nonpoisonous or less toxic oxidant. We report on the use of potassium permanganate as an oxidant to synthesize phenylphenazin-5- ium chlorides via sequential aniline arylation. MATERIALS AND METHODS The corresponding 2-substituted-3-amino-5-phenyl-7-N,N-dimethylamino phenazinium chlorides were obtained via various o-substituted toluidines reacted with 4-amino-N,N-dimethyamine and aniline using potassium permanganate as an oxidant under different conditions such as temperature, pH, reaction time and the ratio of raw materials. Infrared (IR) absorption data were acquired on a Thermo Nicolet Nexus 670 FT-IR spectrometer with DTGS KBr detector. All the products were characterized by Mass, 1H and 13C NMR spectroscopy. The total C, H, N, content was measured by the elemental analyzer. RESULTS The yields of 3-amino-7-(N,N-dimethylamino)-2-substituted-5-phenylphenazin-5-ium chlorides are from 42.5% to 75.8% based on the electrophilic ability of different substituted groups under the temperature of 95°C, pH 4.5 and the reaction time of 8hrs. CONCLUSION 3-Amino-7-(N,N-dimethylamino)-2-substituted-5-phenylphenazin-5-ium chlorides have been synthesized in high yields via the oxidative cyclization with potassium permanganate. This route is a simple, economic, efficient and environmentally friendly.

Abstract
Objective: To report the clinical features of anti-MDA5 antibody positive juvenile dermatomyositis (JDM) complicated with severe interstitial lung disease (ILD). Methods: The clinical data of three patients, who was admitted to the Department of Rheumatology and Immunology, Children's Hospital of the Capital Institute of Pediatrics from September 2016 to July 2017, with anti-melanoma differentiation associated gene 5 (MDA5) antibody positive JDM complicated with ILD were retrospectively extracted and analyzed. Meanwhile, PubMed database, CNKI, Wanfang database and China Biology Medicine disc (from their establishment to February 2019) with the key words "juvenile dermatomyositis" "interstitial lung disease" , and "anti-MAD5 antibody" both in English and Chinese were searched. Results: There were 2 females and 1 male (P1-P3), aged from 10 years 3 months to13 years 4 months, the time from onset to diagnosis were 2 months, 4 months and 10 months. All presented with rash. One of them had decreased muscle strength, and two had decreased activity tolerance. Creatine kinase was 588, 915 and 74 U/L, and serum ferritin were 1 792, >2 000 and 195.4 μg/L. All three patients had positive anti-MDA5 antibodies. At the time of diagnosis, all of them had ILD, pneumothorax and mediastinal emphysema, but had no respiratory symptoms. All three patients received oral methylprednisolone and cyclophosphamide pulse therapy, while human immunoglobulin was given only to P1 and P2. P1 developed rapid progressive pulmonary interstitial disease (RPILD) and died of respiratory failure after 2 months. While P2 and P3 were followed up for 1 to 2 years, who had complete remission, as anti-MDA5 antibody turned to negative and ILD improved significantly. Ten related reports in literature were retrieved, without reported Chinese cases, and most cases initiated with rash and very likely complicated with arthritis. Some of them were more likely to have ILD rather than muscle weakness. It also showed that Japanese JDM children had higher rate of positive anti-MDA5 antibody than patients from the U.S. and U.K., and are more susceptible to ILD and RPILD. The mortality rate of patients with RPILD is extremely high. Conclusions: The cases of JDM with positive anti-MDA5 antibody mainly presented with rash and mild muscle weakness, and could be complicated with ILD, pneumothorax and mediastinal emphysema without respiratory symptoms at early stage. Anti-MDA5 antibody titer is related to disease activity and can turn to negative after treatment.

Abstract
Objective: This study aims to explore the clinical value of fusion indocyanine green fluorescence imaging (FIGFI) in total laparoscopic radical resection for right colon cancer. Methods: From October, 2018 to December, 2018, 15 patients who underwent total laparoscopic radical resection for right colon cancer using FIGFI in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were retrospectively enrolled in this study. Data regarding surgical outcomes, postoperative recovery, pathological outcomes and complications were collected and analyzed. Results: All patients successfully underwent total laparoscopic radical resection for right colon cancer using FIGFI. 1 patients (6.7%) received extended resection of bowel due to poor blood supply after mesentery excision. The average operation time was 133.7 minutes and intraoperative blood loss was 26.7 ml. The average time to ground activities, fluid diet intake, first flatus and postoperative hospitalization were 19.1 h, 11.7 h, 32.5 h and 5.0 d, respectively. The average length of tumor was 4.5 cm. The average proximal and distal resection margins were 14.9 cm and 12.1 cm, respectively. The average number of lymph nodes retrieved was 29.3 per patient. Only one patient suffered from incisional fat liquefaction after surgery and was managed effectively by regular dressing change. No severe complications such as indocyanine green allergy, anastomotic stenosis, anastomotic leakage, abdominal bleeding, bowel obstruction, pulmonary infection, and abdominal infection occurred in any patients. Conclusions: FIGFI is helpful to judge the blood supply of intestinal segments and anastomotic stoma in total laparoscopic radical resection for right colon cancer quickly. It is a safe and feasible technique with satisfactory short-term effect.

Abstract
BACKGROUND As one effective treatment for lateral pelvic lymph node (LPLN) metastasis (LPNM), laparoscopic LPLN dissection (LPND) is limited due to the complicated anatomy of the pelvic sidewall and various complications after surgery. With regard to improving the accuracy and completeness of LPND as well as safety, we tried an innovative method using indocyanine green (ICG) visualized with a near-infrared (NIR) camera system to guide the detection of LPLNs in patients with middle-low rectal cancer.
AIM To investigate whether ICG-enhanced NIR fluorescence-guided imaging is a better technique for LPND in patients with rectal cancer.
METHODS A total of 42 middle-low rectal cancer patients with clinical LPNM who underwent total mesorectal excision (TME) and LPND between October 2017 and March 2019 at our institution were assessed and divided into an ICG group and a non-ICG group. Clinical characteristics, operative outcomes, pathological outcomes, and postoperative complication information were compared and analysed between the two groups.
RESULTS Compared to the non-ICG group, the ICG group had significantly lower intraoperative blood loss (55.8 ± 37.5 mL vs 108.0 ± 52.7 mL, P = 0.003) and a significantly larger number of LPLNs harvested (11.5 ± 5.9 vs 7.1 ± 4.8, P = 0.017). The LPLNs of two patients in the non-IVG group were residual during LPND. In addition, no significant difference was found in terms of LPND, LPNM, operative time, conversion to laparotomy, preoperative complication, or hospital stay (P > 0.05).
CONCLUSION ICG-enhanced NIR fluorescence-guided imaging could be a feasible and convenient technique to guide LPND because it could bring specific advantages regarding the accuracy and completeness of surgery as well as safety.

Abstract
Plant invasion is the outcome of complicated interactions of both biotic and abiotic environments (i.e. eutrophication and human-induced propagules) under global anthropogenic change. Here, we want to know why some alien clonal plant species become invasive and others do not in the introduced range with variations of both abiotic and biotic environments under global anthropogenic change. We selected three invasive alien and three co-occurring, non-invasive alien clonal plant species in China, and grew them under the constant or variable soil nutrient environments in a native community with low or high vegetative propagule pressure (i.e. simulating pressure of anthropogenic alien propagules). Invasive alien species produced more biomass than non-invasives. Interestingly, invasive species benefited significantly greater from high propagule pressure than non-invasives. Biomass and evenness of native communities were greater with non-invasive than with invasive target species. Invasive plants showed a greater increase of leaf N and decrease of leaf C: N ratio when subject to variable nutrients in comparison to constant nutrients than non-invasives. The negative effects of variable nutrients on evenness of native communities were significantly greater under invasive than non-invasive target species. Moreover, biomass of native communities was significantly negatively related to biomass of invasive species. Variable nutrients significantly promoted the negative biomass relationship between non-invasive species and native communities under high propagule pressure and the negative biomass-evenness relationship between invasive species and native communities. Our study suggests that soil nutrient variability and vegetative propagule pressure influence the growth and leaf C and N uptake of alien clonal plant species in native experimental communities, especially under the high propagule pressure and nutrient variability. Invasive alien clonal species have higher performance and advantages over non-invasives. Future studies should also test the mechanisms that invasive and non-invasive or native plants differ in native communities of native or introduced ranges in the field.

Abstract
Objective: The aim of this study was to explore the clinical safety, feasibility and short-term effect of overlapped delta-shaped anastomosis in total laparoscopic transverse colectomy. Methods: The records, which were based on China National Cancer Center, of 20 and 31 patients who underwent total laparoscopic transverse colectomy with overlapped delta-shaped anastomosis and laparoscopic-assisted transverse colectomy with conventional extracorporeal anastomosis, from March 2017 to May 2018 were reviewed retrospectively. Data regarding surgical outcomes, postoperative recovery, pathological outcomes and perioperative complications were collected and compared. Results: There was no difference between the two groups in overall operation time, anastomosis time and intraoperative blood loss (P>0.05), however, the length of incision was significantly shorter in overlapped delta-shaped group [(4.7±0.6) cm vs. (5.5±1.0) cm, P=0.002]. The time to ground activities, first flatus and postoperative hospitalization did not differ between the two groups (P>0.05). The postoperative visual analogue scale was lower in the overlapped delta-shaped group than the control group on postoperative day 1 (3.7±0.7 vs. 4.2±0.9, P=0.015) and postoperative day 3 (2.7±0.5 vs. 3.2±0.9, P=0.040). The perioperative complication rates were 10.0% and 12.9% in the overlapped delta-shaped group and the control group, respectively, and the difference was not significant (P=0.753). Conclusion: Compared to conventional extracorporeal anastomosis, total laparoscopic transverse colectomy with overlapped delta-shaped anastomosis was a safe and feasible procedure with satisfactory short-term effect, shorter incision and less postoperative pain.

A multi-species comparison of selective placement patterns of ramets in invasive alien and native clonal plants to light, soil nutrient and water heterogeneity.

Abstract
A worth noticing pattern in current invasive biology is the clonal ability of many of the world's worst invasive plants. Selective placement of ramets (i.e. foraging behavior) can intensify ramet performance and allocation, and place more ramets in the more favorable microhabitats, which can maximum utilize resource and share risk in heterogeneous environments. Still little is known about whether invasive alien and native clonal plants differ in the selective placement patterns of ramets in invasive clonal plants or not. We used five congeneric pairs of naturally co-occurring invasive alien and native clonal plant species in China. In a glasshouse, we grew all species in pots under a homogeneous and three heterogeneous conditions (i.e. light, soil nutrients or water) subjected to resource-high or -low patches. All biomass parameters and number of ramets significantly increased in resource-high patches in all three types of heterogeneous environments. Interestingly, growth of invasive alien plants benefited significantly more from resource-high patches than native plants in all heterogeneous environments. Overall, invasive had higher biomass parameters per ramet than natives. Ramet parameters of invasive plants also benefited more from resource-low patches than natives. Three different selective placement patterns of ramets in resource-low patches were exhibited in invasive plants: ramet increasing shoot investment (above pattern), increasing root investment (below pattern) and increasing both investments (complete pattern) in the light, soil water and nutrient heterogeneity, respectively. Investment on less, larger ramet was the adaptive strategy of invasive plants in resource-poor patches. The results suggest that adaptively selective placement patterns of ramets promote a higher morphology plasticity and performance in invasive clonal plants over natives. When alien clonal plants spread new areas with light, soil nutrients or water heterogeneity, selective placement patterns of ramets might play an important role in plant performance and competitive superior by capitalizing more on additional resources.

Abstract
Background and objective Intra-corporeal delta-shaped anastomosis (IDA) is an important development in laparoscopic digestive-tract reconstruction. We applied it in laparoscopic right hemicolectomy for right colon cancer and compared the short-term outcomes between the patients treated with IDA and conventional extracorporeal anastomosis (EA). Methods Between 1 January 2016 and 1 October 2017, 36 and 50 patients who underwent IDA and EA, respectively, were included. Data on clinicopathological characteristics, surgical outcomes, post-operative recovery and complications were collected and compared between the two groups. Results Surgical outcomes and clinicopathological characteristics were similar between the two groups except the length of incision, which was significantly shorter in the IDA group than in the EA group (4.6 ± 0.6 vs 5.6 ± 0.7 cm, P < 0.001). The time to ground activities, fluid diet intake and post-operative hospitalization did not differ between the groups; however, the time to first flatus was significantly shorter in the IDA group than in the EA group (2.8 ± 0.5 vs 3.2 ± 0.8 days, P = 0.004). The post-operative visual analogue scale for pain was lower in the IDA group than in the EA group on post-operative Day 1 (4.0 ± 0.7 vs 4.5 ± 1.0, P = 0.002) and post-operative Day 3 (2.7 ± 0.6 vs 3.4 ± 0.6, P < 0.001). The surgical complication rates were 8.3 and 16.0% in the IDA and EA groups (P = 0.470), respectively. No complications such as anastomotic bleeding, stenosis and leakage occurred in any patient. Conclusions IDA is safe and feasible and shows more satisfactory short-term outcomes than EA.

Abstract
Poplar is a major afforestation tree species in flood-prone areas. Here, we compared molecular and physiological responses in the roots of two full-sib poplar clones, LS1 (flood-tolerant) and LS2 (flood-susceptive), subjected to stagnant flooding using transcript and metabolite profiling. LS1 displayed less phenotypic damage and superior leaf gas exchange and plant growth compared with those of LS2. We concluded that three characteristics might contribute to the differences in flood tolerance between LS1 and LS2. First, fermentation was initiated through lactic dehydrogenation in LS1 roots under flooding and subsequently dominated by alcohol fermentation. However, lactic dehydrogenase was persistently active in flooded LS2. Second, 13 differentially expressed genes associated with energy and O2 consumption processes under soil flooding had lower transcript levels in LS1 than those in LS2, which might contribute to better energy-/O2-saving abilities and behaviours in flood-tolerant LS1 than those in flood-susceptible LS2 under hypoxic stress. Third, LS1 possessed increased reactive oxygen species scavenging abilities compared with those of LS2 under edaphic flooding. Our data are a valuable contribution to understanding the mechanisms involved in the flood tolerance of poplar.

Abstract
Objective: The aim of this study was to explore the clinical safety and feasibility of intracorporeal delta-shaped anastomosis in total laparoscopic left hemicolectomy. Methods: From January 1, 2017 to October 1, 2017, 11 patients who were diagnosed with left colon cancer and underwent total laparoscopic left hemicolectomy with intracorporeal delta-shaped anastomosis were retrospectively enrolled in this study. Clinicopathologic characteristics, surgical and postoperative outcomes were collected and analyzed. Results: The median operation time was 121.8 minutes and the median time for anastomosis was 14.9 minutes. The median intraoperative blood loss was 45.5 ml. The lengths of the upper and lower segments of resection from colon cancer were 11.4 cm and 8.5 cm, respectively. The median number of lymph nodes retrieved was 29.5. The median time to ground activities, time to flatus, time to fluid diet intake and length of hospital stay were 1.4 days, 3.0 days, 3.8 days and 6.9 days, respectively. Only one patient suffered from incision infection during his hospitalization due to preoperative long-term smoking history. No mobility related to the anastomosis such as anastomotic bleeding, stenosis, obstruction and leakage occurred in any patients. Conclusion: Total laparoscopic left hemicolectomy with intracorporeal delta-shaped anastomosis is a safe and feasible procedure with a satisfactory short-term effect.

Abstract
Objective: To analyze the clinical characteristics of eperythrozoonosis complicated with hemophagocytic syndrome (HPS) in 4 children. Methods: Four patients diagnosed with eperythrozoonosis complicated with HPS in the Children's Hospital Affiliated Capital Institute of Pediatrics during the period from June 2014 to July 2016 were enrolled. The clinical manifestations, laboratory examination data and therapeutic strategies were analyzed. A literature search (search terms included 'eperythrozoonosis' and 'hemophagocytic syndrome') was conducted using CNKI, Wanfang database, Chinese biomedical literature database and PubMed to include recently published studies (searched from the database establishment to January 2017). Results: Four patients were included in the study. One was boy and the other three were girls. The age range of the 4 patients was between 9 months and 17 years (9 months, 2 years and 17 years, 11 months respectively). All the patients presented with recurrent high fever. During the course of fever, 3 patients presented with rash, and 2 patients presented with joint pain and swelling, which mimicked systemic juvenile idiopathic arthritis. Only 1 patient had the contact history of infectious disease. All patients had normal or decreased white blood cell count ((0.80-13.12)×109/L), suffered from varied degrees of anemia and showed the increased C reactive protein (13.0-84.7 mg/L) anderythrocyte sedimentation rate (13-72 mm/1 h). Examination of peripheral blood smears confirmed eperythrozoonosis. After fever continued about 1 month, all the 4 patients rapidly progressed. Among the 4 patients, 1 patient died for giving up further therapy, and the other 3 patients completely recovered after treatment, including azithromycin for the treatment of eperythrozoonosis, and high-dose intravenous methylprednisolone pulse therapy and human immunoglobulin for the treatment of HPS. For the disease not satisfactory, the hemophagocytic lymphohistiocytosis-2004 (HLH-2004) protocol is given. After the hospitalization of 1 to 2 months, the conditions improved and the children were discharged from hospital. Three patients were followed up for 8 months to 2 years, and their conditions were stable. In the PubMed database, no report was found. Nine cases of children with eperythrozoonosis were found in CNKI, Wanfang database and Chinese biomedical literature database, and 1 case was complicated with HPS. These findings, taken together our report, provided the data of 5 children with eperythrozoonosis complicated with HPS (4 cases were younger than 2 years old). A patient had contact history of infectious disease. Five patientss showed fever of unknown origin. All the patients had severe eperythrozoonosis, and 2 cases at younger age died. Conclusions: Children with eperythrozoonosis often present with the protracted fever of unknown origin, and clinical manifestations mimic those of juvenile idiopathic arthritis (systemic type). The patients with eperythrozoonosis of mild-to-moderate disease severity may have a good prognosis. Children with severe eperythrozoonosis, especially those HPS cases with early onset before 2 years old, may have high risk of mortality. Once the patient's condition aggravates in the course of fever, HPS should be highly suspected. For the patients with eperythrozoonosis complicated with HPS, early diagnosis and the combination of anti-infection with the treatment of HPS are crucial for a good prognosis. For the treatment of HPS, HLH-2004 protocol is recommended.
