Abstract
Objective: To evaluate the safety of early enteral nutrition (EEN) support in patients with severe intra-abdominal infection and intestinal fistulas. Methods: This was a retrospective cohort study. We collected relevant clinical data of 204 patients with severe intra-abdominal infection and intestinal fistulas who had been managed in the No. 1 Department of General Surgery, Shanghai Ninth People's Hospital, Shanghai Jiaotong University between 1 January 2017 and 1 January 2020. The patients were allocated to EEN or delayed enteral nutrition (DEN) groups depending on whether enteral nutrition had been instituted within 48 hours of admission to the intensive care unit. The primary outcome was 180-day mortality. Other outcomes included rates of intraperitoneal hemorrhage, septic shock, open abdominal cavity, bloodstream infection, mechanical ventilation, and continuous renal replacement therapy. Risk factors for mortality were analyzed by logistic regression. Results: There were no significant differences in hematological data or other baseline characteristics between the two groups at the time of admission to the intensive care unit (all P>0.05). However, septic shock (31.2% [15/48] vs. 15.4% [24/156], χ2=4.99, P=0.025), continuous renal replacement therapy (27.1% [13/48] versus 9.0% [14/156], χ2=8.96, P=0.003), and 180-day mortality (31.2% [15/48] vs. 7.7% [12/156], χ2=15.75, P<0.001) were significantly more frequent in the EEN than the DEN group (all P<0.05). Multivariate regression analysis showed that older age (OR=1.082, 95%CI:1.027-1.139,P=0.003), worse Acute Physiology and Chronic Health Evaluation (APACHE) II scores (OR=1.189, 95%CI: 1.037-1.363, P=0.013), higher C-reactive protein (OR=1.013, 95%CI:1.004-1.023, P=0.007) and EEN (OR=8.844, 95%CI:1.809- 43.240, P=0.007) were independent risk factors for death in patients with severe intra-abdominal infection and intestinal fistulas. Conclusion: EEN may lead to adverse events and increase mortality in patients with both enterocutaneous fistulas and severe abdominal infection. EEN should be implemented with caution in such patients.

Abstract
Objective: To explore the characteristics, prevention and treatment strategies of lower urinary tract injury in transvaginal reconstructive pelvic surgery (vRPS). Methods: A retrospective analysis was conducted on 24 patients who suffered lower urinary tract injuries occuring in vRPS from January 2005 to June 2021, among which 4 cases were referred to our hospital from other hospitals. Results: (1) In our hospital, 1 952 patients underwent vRPS for anterior and (or) middle pelvic organ prolapse during that study period, with a 1.0% (20/1 952) incidence of lower urinary tract injuries occurring in 20 cases. (2) Ureteral injuries were observed in 14 cases who underwent transvaginal high uterosacral ligament suspension (1.4%, 14/966). The symptoms were relieved after the removal of sutures. (3) Bladder injuries occurred in 6 cases in our hospital, with 4 cases (0.7%, 4/576) in anterior transvaginal mesh surgery (aTVM), one (0.4%, 1/260) in colpocleisis, and one (0.7%, 1/150) in apical suspension for fornix prolapse. An additional 4 cases of bladder injury were referred to our hospital after aTVM. Among the 8 cases of bladder injury during aTVM, 2 cases were intraoperative incidents. Cystoscopy confirmed that the superficial branch or puncture rod of anterior vaginal mesh had penetrated into the bladder. Re-puncturing and placement of the mesh were successfully performed. No abnormalities were observed during a follow-up period of 4-5 years. Postoperative bladder injuries were identified in 6 cases, characterized by mesh erosion into the bladder and formation of calculi. These injuries were confirmed between 6 months to 2 years after vRPS. The exposed mesh and calculi in the bladder were removed through laparotomy or cystoscopy, followed up for 2-12 years. One case experienced slight re-erosion of mesh to the bladder. Conclusions: Lower urinary tract injuries are difficult to avoid in vRPS, particularly in transvaginal high uterosacral ligament suspension and aTVM. However, the incidence is low. Lower urinary tract injuries during vRPS could be easily detected and managed intraoperatively because of the use of cystoscopy. As long-term postoperative complications, erosion of transvaginal mesh to lower urinary tract postoperatively could be treated correctly, seldom with severe sequelae.

Abstract
Objective: To investigate the trend of postoperative cavity status in patients with eosinophilic chronic sinusitis with nasal polyps (eCRSwNP) who underwent total nasalization surgery and partial reboot surgery. And to discuss the relationship between tissue eosinophil counts and status of postoperative cavity. Methods: Patients with eCRSwNP in four tertiary medical centers (Longgang ENT Hospital, Xiamen Humanity Hospital, Guangdong Clifford Hospital and the First Affiliated Hospital of Sun Yat-Sen University) from March 2018 to October 2021 were divided into 2 groups. The group without previous surgery history was performed for the nasalization surgery, and another group with previous surgery history underwent the part-reboot surgery. The follow-up time after operation was defined as the following 5 stages: 6, 12, 20-24, 36 and more than 42 months. According to FESS-95 Guangzhou standard, status of sinus cavity was assessed and classified into 3 categories: good, better and bad. The association between the sinus cavity status and tissue eosinophil counts in the above 5 stages was analyzed by one-way ANOVA, and P<0.05 was considered statistically significant. Results: A total of 72 eCRSwNP patients finished the follow-up in this study. There were 47 males and 25 females in these patients, aged from 11 to 67 years. A total of 50 cases underwent nasalization surgery and 22 cases underwent partial reboot surgery. With the follow-up time from 6 to 48 months, there were 72 cases (100.0%) who completed 6 months and 12 months follow up, 46 cases (63.9%) for 20-24 months, 36 cases (50.0%) for 32-36 months and 16 cases (22.2%) with the follow-up time more than 42 months. No matter what kind of surgery, there was no "bad" situation of the surgical cavity status 6 months after the operation, and the differentiation gradually occurred more than 12 months after the surgery. Moreover, the rates of "good" cavity status for the 5 stages in the group of nasalization surgery were 78.0%, 66.0%, 56.7%, 47.6% and 42.9%, and were 63.6%, 45.5%, 25.0%, 20.0% and 11.1% in the partial reboot surgery group, respectively, suggesting that the status of nasal cavity in nasalization surgery group was always better than that in partial reboot surgery group in every period. In addition, the "bad" rate was 0, 8.0%, 10.0%, 14.3% and 28.6% in the group of nasalization surgery, and was 0, 27.3%, 18.8%, 33.3% and 55.6% in the partial reboot surgery group, respectively. The average percentage of tissue eosinophil counts in the 72 cases was 42.1%, which had no obvious effect on the status of the surgical cavity (P>0.05). Conclusions: For eCRSwNP patients, the operative cavity status in the patients without previous operation history treated with nasalization surgery is good. The time of 1-2 years after surgery is the main period for sinus lesions. The counts of tissue eosinophils has no significant influence on surgical sinus cavity status in the eCRSwNP patients.

Abstract
Objective: To understand the common viral infection among the surveillance cases of fever respiratory syndrome (FRS) in nine provinces in China. Methods: The research data were obtained from nine provinces (Anhui, Beijing, Guangdong, Hebei, Hunan, Jilin, Shandong, Shaanxi and Xinjiang) in the "Infectious Disease Surveillance Technology Platform Information Management System" of the Chinese Center for Disease Control and Prevention from January 2009 to June 2021. Finally, 8 243 FRS cases with nucleic acid detection results of eight viruses [human influenza virus (HIFV), human respiratory syncytial virus (HRSV), human adenovirus (HAdV), human parainfluenza virus (HPIV), human rhinovirus (HRV), human metapneumovirus (HMPV), human coronavirus (HCoV) and human Boca virus (HBoV)] were included in the study. The χ2 test/Fisher exact probability method was used to analyze the difference of virus detection rate in different age groups, regions and seasons. Results The M (Q1, Q3) age of 8 243 FRS cases was 4 (1, 18) years old, and 56.56% (4 662 cases) were children under 5 years old. Males accounted for 58.1% (4 792 cases) of all cases. All cases were from outpatient/emergency department (2 043 cases) and inpatient department (6 200 cases). The virus detection rates of FRS cases from high to low were HRSV, HIFV, HPIV, HRV, HAdV, HMPV, HCoV and HBoV. Two or more viruses were detected simultaneously in 524 cases, accounting for 15.66% of virus-positive cases. The difference of the virus detection rate in different age groups was statistically significant (all P values<0.05), and the virus detection rate in children<5 years old was higher (49.96%). The positive rate of any virus in south China was higher than that in north China (P<0.001). The virus-positive FRS cases were detected throughout the year. The detection rate of HRSV was higher in autumn and winter. The detection rate of HIFV was higher in winter. The detection rate of HMPV was higher in winter and spring. The detection rates of HPIV, HRV, HCoV and HBoV were higher in summer and autumn, while there was no significant difference in the detection rate of HAdV in different seasons. Compared with 2009-2019, the detection rate of any virus in 2020-2021 decreased from 41.37% to 37.86%. The detection rate of HIFV decreased sharply from 10.62% to 1.37%. The detection rate of HPIV decreased from 8.24% to 5.88%. The detection rate of HRV and HBoV increased from 5.43% and 1.79% to 9.67% and 3.19%, respectively. Conclusion: HRSV and HIFV infections are more common among FRS cases in nine provinces in China from 2009 to 2021, and the epidemiological characteristics of eight common respiratory viruses vary in different age groups, regions and seasons.

Abstract
Objective: To analyze the genotype characteristics of children with monogenic nephrolithiasis. Methods: The clinical data and genetic test results of 56 children with monogenic nephrolithiasis diagnosed and treated in Beijing Friendship Hospital, Capital Medical University from January 2016 to December 2020 were analyzed retrospectively. All pediatric patients were diagnosed by whole exome sequencing, and the genotype characteristics of the children were analyzed. Results: Among 56 children with monogenic nephrolithiasis, there were 39 males and 17 females, with an average age of 4 years (range, 5 months to 14 years). A total of 11 genes were found to have mutations, including 7 autosomal recessive genes, 1 X-linked recessive gene, and 3 genes with both recessive and dominant, of which HOGA1 gene mutation was the most common (16 cases, 28.6%), followed by AGXT gene (15 cases, 26.8%), SLC3A1 gene (6 cases, 10.7%), SLC7A9 gene (5 cases, 8.9%) and GRHPR gene (5 cases, 8.9%). The mutation types included nonsense mutations, frameshift mutations and splicing mutations, with 14 novel mutations. Genes such as AGXT, GRHPR and HOGA1 have hotspot mutations or hotspot mutation regions, which are c. 815-816 insGA and c. 33dupC mutation, c.864-865delTG mutation and c. 834-834+1 mutation region; SLC3A1 and SLC7A9 genes had 9 novel mutations, but no hotspot mutation or hotspot regions were found. Conclusion: Monogenic nephrolithiasis is rare and mostly autosomal recessive in Chinese children, with mutations in the causative genes HOGA1, AGXT, SLC3A1,SLC7A9 and GRHPR. AGXT, GRHPR and HOGA1 genes have hotspot mutations or hotspot mutation regions, and mutations may have ethnic differences.

Abstract
Abstract
Background and aims
The present study aimed to develop and validate separate risk prediction models for thrombosis events (TEs) and major bleeding (MB) in patients with multi-vessel coronary artery lesions who had undergone primary percutaneous coronary intervention (PCI).
Methods and results
TEs were defined as the composite of myocardial infarction recurrence or ischemic cerebrovascular events, whereas MB was defined as the occurrence of bleeding academic research consortium (BARC) 3 or 5 bleeding. The derivation and validation cohorts comprised 2976 patients who underwent primary PCI between January 2010 and June 2017. At a median follow-up of 3.07 years (1122 days), TEs and MB occurred in 167 and 98 patients, respectively. Independent predictors of TEs were older age, prior PCI, non-ST elevated MI (NSTEMI), and stent thrombosis (ST). Independent predictors of MB were triple therapy at discharge, coronary artery bifurcation lesions, lesion restenosis, target lesion of the left main coronary artery, and PTCA. In the derivation and validation cohorts, the areas under the curve were 0.817 and 0.820 for thrombosis and 0.886 and 0.976 for bleeding, respectively. In the derivation cohort, high thrombotic risk (n=755) was associated with a higher 3-year incidence of TEs, major adverse cardiovascular events (MACEs), and all-cause death, compared to low risk (n=1275) (p=0.0022, 0.019, 0.012, respectively). High bleeding risk (n=1675) was associated with a higher incidence of bleeding, MACEs, cardiac death, compared to low risk (n=355) (p<0.0001).
Conclusion
Simple risk scores can be useful in predicting the risks of ischemic and bleeding events after primary PCI, thereby stratifying thrombotic or MB risks and facilitating clinical decisions.

Abstract
PURPOSE To compare the clinical outcomes of patients with and without early enteral nutrition after colorectal cancer surgery. METHODS This is a retrospective comparative study using propensity score-matched cases. The study subjects were patients who received colorectal cancer resection surgeries during 2013 and 2018 in a Taiwan medical center. Data of the following variables were retrieved from subjects' medical records: age, sex, diagnosis, pathological stage, surgical approach, comorbidity, risk of malnutrition, anesthesia duration, enteral nutrition, time to the first postoperative flatus, time to the first defecation, feeding associated symptoms, nutrition interruptions, time to achieve nutrition goals, postoperative complications, the length of hospital stay. Subjects who received enteral nutrition within 48 h after the surgery were considered as the early enteral nutrition group. RESULTS After propensity score matching, 227 subjects in each group were included in the final analysis. The early enteral nutrition group showed better results in the time to first postoperative flatus (mean difference: 0.96, 95% confidence interval: 1.16 ~ -0.76), the time to achieve nutrition goals (mean difference: 1.26, 95% confidence interval: 0.65 ~ -1.87), and the length of hospital stay (mean difference: 1.53, 95% confidence interval: 2.56 ~ -0.42), compared with the delayed enteral nutrition group. There were no between-group differences in the incidences of vomiting, distension, ileus, anastomosis leak, infection, re-operation, and interruptions of enteral nutrition. CONCLUSIONS Enteral feeding after colorectal cancer surgery can accelerate the recovery of gastrointestinal tract activities, promote nutrient intake, and shorten the length of hospital stay without increasing postoperative complications.

Abstract
Objective: To analyze and summarize the diagnosis, treatment and prognosis of granulomatosis with polyangiitis (GPA) with nasal symptoms as the first clinical manifestation. Methods: The data of 18 patients of GPA with nasal mucosal symptoms as the first clinical manifestation from the Department of Otorhinolaryngology Head and Neck Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University between 2005 and 2019 was collected, including 8 males and 10 females, aged from 5 to 68 years. Nasal endoscopy, imaging examination, laboratory examination, immunological and histopathological examination of nasal mucosa were completed. All patients were treated with glucocorticoid combined with cyclophosphamide and were followed up for 2 to 15 years. Descriptive statistical method was used for analysis. Results: All the 18 patients had the nasal mucosal symptoms as the first clinical manifestation, including nasal obstruction, running nose and epistaxis. Nasal endoscopy showed swelling, erosion, scab and bleeding of nasal mucosa, and 6 cases had nasal septal perforation. Nasal sinus CT scan showed high density shadow of sinus, as well as hyperostosis and osteosclerosis. CT imaging features of pulmonary showed nodular lesion or patchy infiltration in 12 patients and cavitation was found in 6 cases. Laboratory results showed that 13 cases were positive for anti-neutrophil cytoplasmic antibodies (ANCA), and 5 cases were negative. During follow-up period, thirteen patients were symptomatic controlled and survived; two patients died of disease progression; one patient gave up treatment and died; two patients were lost to follow-up. Conclusions: Nasal symptoms are the first clinical manifestation of GPA. Early diagnosis and early treatment with glucocorticoid combined with cyclophosphamide can effectively improve the survival rate.

Abstract
Objective: To evaluate the indications, surgical skills and clinic outcomes of abdominal minimal incision sacrocolpopexy (AMISC) for treatment of advanced pelvic organ prolapse (POP). Methods: The retrospective study analyzed 30 women with advanced POP who underwent AMISC between June 2016 and October 2019, including 9 cases of recurrent prolapse and 10 cases of vault prolapse. AMISC was especially applicable to: (1) patients with several medical complications who was unable to tolerate general anesthesia or laparoscopic surgery, but able to tolerate combined spinal-epidural anesthesia and open surgery; (2) other abdominal procedures were indicated to perform with AMISC simultaneously, such as myomectomy, subtotal hysterectomy etc, the specimens were easy to get out of the abdominal cavity and morcellation was avoided; (3) surgeons preferring open surgery to laparoscopic surgery or skilled in open surgery; (4) patients with prior pelvic operations, presenting severe abdominal and pelvic adhesions. Objective outcomes were assessed by pelvic organ prolapse quantification (POP-Q) system. Subjective outcome were assessed by pelvic floor distress inventory-short form 20 (PFDI-20), pelvic floor impact questionnaire-short form (PFIQ-7) and patient global impression of improvement (PGI-I). Results: All patients with 1-3 medical complications were successfully performed with AMISC without stopping procedure, enlarging the incision or changing to other procedure, the operation duration was (110±19) minutes. The mean time of follow-up was (33.5±12.4) months (range: 8-49 months). The postoperative points of Aa, Ba, C, Ap, Bp reduced significantly and point C improved from (2.33±2.50) cm to (-7.54±1.18) cm after AMISC (P<0.01). The objective cure rates were both 100% (30/30) in apex and posterior compartment, while 97% (29/30) in anterior compartment. Postoperative scores of PFDI-20 and PFIQ-7 were all significant decreased (all P<0.01). About PGI-I, 29 patients chose "significant improvement", subjective satisfaction was 97% (29/30). Anterior sacral plexus hemorrhage occurred in 2 cases (7%, 2/30). There was no intestinal obstruction or injury of bladder, bowel and ureter intra- and postoperation. Two cases (7%, 2/30) had mesh exposure. Conclusion: AMISC is a safety, convenient, minimal traumatic and durable procedure for apical prolapse with short learning curve in the most of cases.

Abstract
Objective: To evaluate the prognosis of tooth extraction in elderly mellitus patients with fasting plasma glucose (FPG)>8.88 mmol/L and ≤10.00 mmol/L. Methods: This study was a prospective cohort study. One hundred elderly mellitus patients, 53 males and 47 females, aged 65-95 years old (75.8±8.0), were recruited for tooth extraction at the ECG monitoring out-patient clinic in the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from Oct 2018 to Oct 2019. Fifty cases were selected into the observation group with FPG>8.88 mmol/L and ≤10.00 mmol/L before tooth extraction, while the rest 50 cases were in the control group with FPG≤8.88 mmol/L. The levels of glycosylated hemoglobin (HbA1c) of patients were required to be≤8.5% before tooth extraction in both groups. Post-operative pain, swelling, pus discharge, fistula at local sockets and systemic fever were observed 24 h and 1 week after the extraction. The healing of tissues around the extraction socket was observed 1 month after operation. The correlation between blood glucose control target and the effects of socket healing before and after tooth extraction was analyzed statistically using SPSS 25.0 software. Results: The pre-operative FPG levels of observation group and control group were (6.92±0.99) and (9.88± 0.68) mmol/L, and HbAlc levels were (6.76±0.83)% and (7.69±0.75)%, respectively. There were no significant differences in age, gender, diabetes history, extraction position, gingival index and tooth looseness between the two groups (P>0.05). Ninety-four percent (47/50 in each group) of patients in the two groups healed well within 24 h after the extraction. There were 6 patients, 3 in each of the two groups, complained tolerable post-operative pain in tooth extraction sockets. However, no redness, swelling and pus in the surrounding tissues were observed. There was no statistical difference of socket healing after the extractions between two groups (P>0.05). Conclusions: The pre-operative levels of FPG≤10.00 mmol/L and HbA1c≤8.5% are reasonable creteria for evaluating tooth extraction risk for the elderly diabetic patients.

Abstract
Objective: To investigate the prevalence of asthma among the elderly people in China and to analyze the clinical features, self-management and cognitive level of elderly asthma patients. Methods: According to the multi-stage random cluster sampling methods, a total of 164 215 subjects were visited by a questionnaire in the last epidemiology survey from eight provinces (Beijing, Shanghai, Guangdong, Liaoning, Henan, Shanxi, Jiangsu, Sichuan provinces) and seven regions (north, northeast, southern china, east, south, southwest and northwest) in China from February 2010 to August 2012. 2 034 were diagnosed as asthma. The elderly patients aged ≥65 years were selected from the 2 034 asthma patients. The clinical characteristics, comorbidities, the status of asthma control and self-management and insights of the disease in elderly asthma patients were analyzed. Results: Among the 2 034 asthma patients, 584 (28.7%) were elderly asthmatics aged ≥65 years old and 1 450 (71.3%) were<65 years old. In the elderly asthma group, Early-onset asthma accounted for 439 (75.2%) and 145 (24.8%) were late-onset. The common clinical manifestations of elderly asthma patients were: chest distress 395 (67.6%), wheezing 304 (52.1%), cough 298 (51.0%). Common comorbidities of elderly asthmatics were: chronic obstructive pulmonary disease 144 (24.7%), allergic rhinitis 122(20.9%), gastroesopheal reflux disease (GERD) 114(19.5%), allergic conjunctivitis 86 (14.7%), eczema 82 (14.0%), chronic bronchitis 76 (13.0%). The Asthma Control Test (ACT) scores of elderly asthmatics and non-elderly asthmatics were (18.5±3.2) and (21.7±3.4) respectively. There was a significant difference between the two groups (P=0.042). Of the elderly asthmatics, only 13 (2.2%) patients monitored daily using a peak flow meter. 93 (15.9%) patients aware that asthma was characterized by chronic airway inflammation. 64 (11.0%) asthmatics understood that the treatment goal. Conclusions: The clinical manifestations of elderly asthmatics are atypical, especially paroxysmal wheezing. Asthma in elderly people causes more comorbidities and mortality. The self-management and cognitive level of patients with asthma needs to be improved.

Abstract
Objective: To investigate the clinical characteristics and risk factors of severe bronchial asthma in Chinese people over 14 years old. Methods: According to the multi-stage random cluster sampling methods, a total of 164 215 subjects were visited by a questionnaire in the epidemiology survey from eight provinces (Beijing, Shanghai, Guangdong, Liaoning, Henan, Shanxi, Jiangsu, Sichuan provinces) located in seven regions (north, northeast, east, central China, south, southwest and northwest) of China from February 2010 to August 2012. A total of 2 034 were diagnosed as asthma. The clinical characteristics and related risk factors of patients with severe asthma in China were analyzed. Results: Among all asthma patients, 560 were newly diagnosed, accounting for 27.5% (560/2 034) and the percentage of previously confirmed patients was 72.5% (1 474/2 034). A total of 145 were eligible for severe asthma, accounting for 9.8% (145/1 474) of previously confirmed asthmatics and 7.1% (145/2 034) of all asthmatics. 83.5% (121/145) severe asthmatics had at least one trigger factor. Correlation analysis showed that the risk factors of severe asthma were: smoking (OR=1.543, 95%CI: 1.250-1.814), obesity (OR=2.186, 95%CI: 1.972-2.354), petting (OR=2.135, 95%CI: 1.904-2.283), combined with allergic rhinitis (OR=3.456, 95%CI: 2.721-4.326), gastroesophageal reflux disease (OR=1.842, 95%CI: 1.682-2.140), bronchiectasis (OR=1.665, 95%CI: 1.347-1.912) or chronic obstructive pulmonary disease (OR=1.312, 95%CI: 1.171-1.694). Conclusions: The most common comorbidities in severe asthmatics in China are allergic rhinitis and gastroesophageal reflux disease. The risk factors of severe asthma include obesity, allergic rhinitis, gastroesophageal reflux disease, chronic obstructive pulmonary disease, bronchiectasis, smoking and petting.

Abstract
Objective: To understand the consistency of ALK Ventana-D5F3 immunohistochemistry (IHC) interpretation in Chinese lung adenocarcinoma among histopathologists from different hospitals, and to recommend solution for the problems found during the interpretation of ALK IHC in real world, with the aim of the precise selection of patients who can benefit from ALK targeted therapy. Methods: This was a multicenter and retrospective study. A total of 109 lung adenocarcinoma cases with ALK Ventana-D5F3 IHC staining were collected from 31 lung cancer centers in RATICAL research group from January to June in 2018. All cases were scanned into digital imaging with Ventana iSCANcoreo Digital Slide Scanning System and scored by 31 histopathologists from different centers according to ALK binary (positive or negative) interpretation based on its manufacturer's protocol. The cases with high inconsistency rate were further analyzed using FISH/RT-PCR/NGS. Results: There were 49 ALK positive cases and 60 ALK negative cases, confirmed by re-evaluation by the specialist panel. Two cases (No. 2302 and No.2701) scored as positive by local hospitals were rescored as negative, and were confirmed to be negative by RT-PCR/FISH/NGS. The false interpretation rate of these two cases was 58.1% (18/31) and 48.4% (15/31), respectively. Six out of 31 (19.4%) pathologists got 100% accuracy. The minimum consistency between every two pathologists was 75.8%.At least one pathologist gave negative judgement (false negative) or positive judgement (false positive) in the 49 positive or 60 negative cases, accounted for 26.5% (13/49), 41.7% (25/60), respectively, with at least one uncertainty interpretation accounted for 31.2% (34/109). Conclusion: There are certain heterogeneities and misclassifications in the real world interpretation of ALK-D5F3 IHC test, which need to be guided by the oncoming expert consensus based on the real world data.

Abstract
Objective: To assess the five-year effect of the transvaginal high uterosacral ligament suspension (HUS) with or without additional concomitant native-tissue anterior and (or) posterior repair in women suffering from middle compartment defect. Methods: A retrospective review of records identified 79 women who underwent transvaginal HUS with or without additional concomitant native-tissue anterior and (or) posterior repair from January 2007 to January 2018 in Fourth Medical Center, General Hospital of People's Liberation Army. The middle compartment defects were predominant in these patients with point C no less than point Ba or Bp if accompanied with anterior or posterior vaginal wall prolapse. Follow-up visits were performed 2,6 and 12 months after surgery and then annually. Anatomic results of pelvic organ prolapse (POP) was established by pelvic examination using pelvic organ prolapse quantitation system (POP-Q) staging. Funtional results were obtained by patient global impression of improvement (PGI-I) scale in POP, pelvic floor distress inventory-short form 20 (PFDI-20) and pelvic floor impact questionnaire short form (PFIQ-7). Surgical success required the fulfillment of all 3 criteria: (1) anterior or posterior vaginal wall prolapsed leading edge of 0 cm or less and apex of 1/2 total vaginal length or less; (2) the absence of POP symptoms as reported on the PFDI-20 question No.3 ( "Do you usually have a bulge or something falling out that you can see or feel in your vaginal area?" ); and (3) no prolapse reoperations or pessary use during the study period. Results: Of 79 women, 51(65%, 51/79) women completed the five-year follow-up during the study period. The median follow-up time was 5.2 years (2.8-8.3 years). The overall surgery success rate was 86% (44/51) according to above all 3 criteria. Prolapse recurrence rates were isolated anterior 8% (4/51), isolated apical 0, isolated posterior 2% (1/51) and multiple compartments 4% (2/51). Seven women (14%,7/51) developed anterior or posterior prolapse beyond the hymen with the leading edge≤1 cm. No apical prolapsed occurred. None of recurrent women underwent retreatment,including either surgery or pessary usage at last follow-up. The subjective satisfaction rate was 90% (46/51). There was a 1% (1/79) rate of intraoperative ureteral kinking and 3% (2/79) rate of postoperative morbidity. Conclusions: The transvaginal HUS for middle compartment defect offers good long-term anatomical results with excellent vault suspension. With additional concomitant native-tissue anterior and (or) posterior repair, it will be a reconstructive surgery for the majority of moderate-to-severe POP. It is minimal traumatic and worthy of being popularized for clinical application.

Abstract
Objective: To evaluate the indications and clinic outcomes of vaginal high uterosacral ligament suspension (HUS) for treatment of recurrent advanced pelvic organ prolapse (POP). Methods: This retrospective study analyzed 42 women with recurrent advanced POP who were referred to Fourth Medical Center of PLA General Hospital and underwent transvaginal HUS between November 2005 and January 2018. Primary surgeries included 30 vaginal colporrhaphy, 5 Manchester operation, 5 transvaginal mesh repair,2 sacrospinous ligament fixation.The median time for recurrence from primary pelvic floor repair surgery was 9 months, including 14 cases (33%, 14/42) ≤3 months (median time was 2 months) and 25 cases (67%, 28/42) longer than 3 months (median time was 18 months).The rate of recurrent prolapse in stage Ⅲ or Ⅳ was 79% (33 cases), 45% (19 cases) and 17%(7 cases) in anterior, apical and posterior compartment respectively. Results: Transvaginal high bilateral uterosacral ligaments were identified and used for successful vaginal vault suspension after vaginal hysterectomy and residual cervical resection in all 42 consecutive patients. The cases of transvaginal mesh used in anterior wall and posterior wall were 25 (60%, 25/42) and 3 (7%, 3/42) respectively. There was no major intra- and postoperative complications,such as ureter and other pelvic organ injury. The median time of follow-up was 5.3 years after transvaginal HUS. The points of pelvic organ prolapse quantification system reduced significantly and point C improved from +0.3 cm to -8.2 cm after reoperation (P<0.01). The objective cure rate were 100% (42/42) both in apex and posterior compartment,while 93% (39/42) in anterior compartment. None had reoperation or pessary usage for recurrence of prolapse. Conclusion: Transvaginal HUS with vaginal wall repair could be as a safety, cost-effective, minimal traumatic and durable procedure for recurrent POP in the most of cases.

Abstract
Objective: Exosomes are considered to mediate intercellular communication by delivering biomolecules like mRNA, miRNA into recipient cells. The purpose of this study was to evaluate the effects of exosomes secreted by fibroblasts from women with stress urinary incontinence (SUI-EXO) on endothelial cells angiogenesis. Methods: Primary fibroblasts were acquired from periurethral vaginal wall tissues and exosomes were prepared by ultracentrifugation of fibroblasts cells conditioned medium. The expression levels of pro-angiogenic and anti-angiogenic genes were assessed using qRT-PCR analysis. Migration of endothelial cells was measured by transwell assay, and the effects of SUI-EXO on angiogenesis were evaluated by performing a tube formation assay in vitro. Results: SUI-EXO was successfully isolated from fibroblasts cells conditional medium and transferred to endothelial cells efficiently. When the endothelial cells were treated with SUI-EXO, the expression levels of pro-angiogenic genes in fibroblasts were downregulated, and the expression levels of anti-angiogenic genes were upregulated significantly (P<0.01). Endothelial cells exhibited a decreased migratory capacity after treatment with SUI-EXO compared to exosomes from health women (64.6±8.7 vs 114.5±14.2,P<0.01), and tube formation of endothelial cells was also significantly inhibited in the SUI-EXO treated group as determined by the increase of the tube length (87.6±13.3 vs 168.5±28.3,P<0.01). Conclusion: This study suggests that SUI-EXO plays related roles in regulating endothelial cells angiogenesis and SUI-EXO maybe involve in the pathogenesis of SUI.

Abstract
BACKGROUND A histological, tumour-free surgical margin does not guarantee recurrence-free survival in patients with cancer. This study investigated the association between microsatellite alteration in tumour-free surgical margins and local recurrence in patients with oral cavity squamous cell carcinoma. METHODS Patients with histologically confirmed oral cavity squamous cell carcinoma were enrolled in this prospective study. Cancerous specimens, corresponding surgical margins and peripheral blood were obtained. Microsatellite alteration was investigated using six dinucleotide microsatellite markers. All samples were amplified by PCR, followed by automatic fragment analysis. RESULTS Microsatellite alteration was identified in 100 specimens (69·0 per cent) from 145 patients. Among them, 85 specimens carried loss of heterozygosity, whereas 55 had microsatellite instability (MSI). Patients with MSI at the surgical margin had a higher risk of local recurrence on multivariable analysis (odds ratio 7·17, 95 per cent c.i. 3·49 to 14·73). CONCLUSION Molecular assessment of surgical margins can help identify patients at risk of local recurrence.

Abstract
As a newly developed technique for hemodynamic monitoring, pulse contour cardiac output (PiCCO) monitoring takes great advantages in guiding shock resuscitation and fluid administration. PiCCO has been used more and more in burn patients in recent years, however there is no clinic consensus on how to apply PiCCO monitoring, understand the significance of PiCCO monitored parameters, and guide the treatment using PiCCO monitored parameters in patients with severe burns. Based on the current literatures and the experts' clinical experience, national experts consensus on application of pulse contour cardiac output monitoring technique in severe burn treatment (2018 version) is now issued by the Burn and Trauma Branch of Chinese Geriatrics Society, aiming to provide practical guidance for its usage in clinic.

Abstract
Objective: This cross-sectional study aimed to address the relationship between the volume of epicardial adipose tissue (EAT) with cardiovascular risk factors and coronary artery calcification(CAC) in the community residents. Methods: Individuals were recruited from the Jidong Community (Tangshan City, Northern China) which mainly comprised employees of the Jidong Co. Ltd. and their family members. From July 2013 to August 2014, 2 647 participants aged ≥40 years were included in this study. The volume of EAT and coronary artery calcification score (CAC score) were determined by a 64-slice CT. Carotid intima-media thickness (CIMT) was measured by a trained sonographer using a high-resolution B-mode topographic ultrasound system. Venous blood samples were analyzed by automated analyzers in the central laboratory. A validated questionnaire specifically designed for this study was used to collect demographic data from all participants by trained doctors. Characteristics of study cohort were compared according to quartiles of EAT volume (n=660, 663, 662, 662, repectively). Results: (1) The mean age of participants was (55.31±7.76) years and 49.94% (n=1 322) were men. The median EAT volume (interquartile) was 129.42 (95.66, 176.51)cm(3). (2) Age, BMI, waist circumference and hip circumference, systolic blood pressure, LDL-C, triglycerides, and fasting blood glucose were significantly higher, while HDL-C level was significantly lower in participants with higher EAT volume than participants with lower EAT volume (all P<0.05). Carotid intima-media thicken (CIMT) and higher CAC score were also significantly higher in participants with higher volume of EAT. Furthermore, percentage of diabetes mellitus, hypertension, hyperlipidemia increased in proportion with increasing EAT volume (P<0.05). (3) In the linear regression, significant positive relations were found for age (β=0.019 3, 95%CI 0.017-0.021, P<0.001), waist circumference (β=0.012 7, 95%CI 0.009-0.016, P<0.001), BMI (β=0.022 4, 95%CI 0.013-0.032, P<0.001), LDL-C (β=0.048 4, 95%CI 0.021-0.076, P<0.001), and HDL-C (β=-0.098 1, 95%CI-0.164--0.032, P<0.001) was inversely related to the EAT volume. (4) Logistic regression analysis indicated that EAT volume was an independent risk factor for CAC score>0 (OR=1.233, 95%CI 1.205-1.262, P<0.001) . Conclusions: Our findings indicate that EAT volume is strongly correlated to cardiovascular risk factors and coronary calcification and is an independent risk factor of increased coronary calcification in community residents.

Abstract
A novel allelic variant in HLA-B*40 lineage, HLA-B*40:298:02, has been identified in an individual of Han ethnicity afflicted with nasopharyngeal carcinoma in Hunan province, southern China. Following polymerase chain reaction-Sanger sequence-based typing (PCR-SBT), this new variant was further confirmed by two distinct strategies of cloning and sequencing. HLA-B*40:298:02 differs from HLA-B*40:298:01 by a single synonymous cytosine substitution at nucleotide position 26 (T→C) in exon 3, which corresponds to codon 99 of the mature HLA-B mRNA molecule. This new allele has an estimated frequency of 0.0002, in about 2,500 sequence-based typed subjects from the same population.

Abstract
Objective: To determine whether thyroid hormone (TH) level could also be an independent and incremental predictor of adverse events in patients with hypertrophic cardiomyopathy (HCM). Methods: A total of 982 consecutive patients with HCM at the National Center for Cardiovascular Diseases (China) from October 2009 to December 2013 were included in the present study, and followed up till the end of December 2016. The patients were divided into three groups according to the levels of free triiodothyronine (FT3): the group 1 (FT3≤4.28 pmol/L, n=335), the group 2 (FT3>4.28-<4.79 pmol/L, n=310), and the group 3 (FT3 4.79-6.30 pmol/L, n=337). Results: After a follow-up period of (53.8±14.1) months, 39 patients (4.0%) either suffered death with all causes or received a cardiac transplantation (7.8%, 2.9% and 1.2% of the patients in the group 1, group 2 and group 3, respectively). A multivariable Cox regression analysis revealed that FT3≤4.28 pmol/L was associated with a significantly higher risk of all-cause mortality or cardiac transplantation (HR 8.83, 95% CI 1.115- 69.905,P=0.039) in HCM patients. Conclusions: Low levels of FT3 is a risk factor of adverse events for patients with HCM, indicting a role of FT3 as a marker for assessing the risk of long-term adverse events in these patients.

Abstract
Objective: To determine the value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) on predicting the long-term outcome of patients with hypertrophic cardiomyopathy (HCM) . Methods: NT-proBNP was measured in 831 consecutive patients with HCM at Fuwai Hospital from October 2009 to December 2013 and patients were followed up clinically for (53.3±15.4) months. Patients were divided into 3 groups according to NT-proBNP values: NT-proBNP<860 pmol/L (n=276) , 860 pmol/L≤NT-proBNP≤1 905 pmol/L (n=278) , NT-proBNP>1 905 pmol/L (n=277) . The related baseline data, laboratory examination and echocardiographic results were compared among groups. The primary endpoints of this study were all-cause mortality and cardiac transplantation. Cox proportional hazards model was used to estimate hazard ratio (HR) . Kaplan-Meier analysis was used to evaluate the survival status of patients among the 3 groups. Results: During a median follow-up of (53.3±15.4) months, all-cause mortality or cardiac transplantation occurred in 37 patients (4.5%) , event rate was 1.4% (4/276) , 4.0% (11/278) and 7.9% (22/277) in patients with NT-proBNP<860 pmol/L, 860 pmol/L≤NT-proBNP≤1 905 pmol/L and NT-proBNP>1 905 pmol/L, respectively. Multivariable Cox regression analysis identified that age (HR 1.066, 95%CI 1.027-1.107) and NT-proBNP (HR 1.026, 95% CI 1.010-1.042) were independent predictors of all-cause mortality or cardiac transplantation. Among the 3 groups, the survival rate of the NT-proBNP<860 pmol/L group was the highest,and that of the NT-proBNP>1 905 pmol/L group was the lowest (P<0.01) . Conclusions: The level of NT-proBNP provides clinically relevant information for long-term adverse events risk stratification in patients with HCM.

Abstract
Objective: To evaluate the value and feasibility of preservation of the left colonic artery (LCA) in laparoscopic anterior resection for rectal cancer. Methods: The clinical data of 97 patiens who received laparoscopic anterior resection of rectal cancer from 2009.3 to 2015.3 were randomly divided into two groups, including 52 cases with preservation of LCA and 45 cases without preservation of LCA. The operation time, quantity of bleeding, number of lymph nodes removed around the root of inferior mesenteric artery (IMA), the rate of lymph node metastasis around the root of IMA, the incidence of transverse colostomy and anastomotic leak were compared between the two groups. Results: All 97 operations were successfully completed by laparoscopic operation. There were significantly statistical differences in operation time, quantity of bleeding and transverse colon stoma between two groups(P<0.05), but no difference in the number of lymph nodes removed and the rate of lymph node metastasis. Conclusions: The preservation of the left colonic artery in laparoscopic anterior resection of rectal cancer can preserve more supplying vessels for anastomosis and prevent anastomotic leak.

Abstract
Objective: To compare the curative effect of two different artificial tears on dry eye after phacoemulsification. Methods: Prospective randomized controlled clinical trial. From March to June in 2012, 102 patients (102 eyes) with age-related cataract were treated with phacoemulsification at Beijing Tongren Hospital, Capital University of Medical Sciences, and these eyes were randomly divided into blank group (group A ) 32 cases, treatment group 1 (group B) 35 cases and treatment group 2 (group C) 35 cases. Group A was treated with conventional antibiotics. Group B was sodium hyaluronate eye drop, group C was lipid-containing carbomer gel respectively. All patients finished a dry eye questionnaire called Ocular Surface Disease Index (OSDI), and Schimmer's test (SIt), break up time (BUT) and fluorescein staining (FL) tests were performed before surgery and at 7, 30 and 90 days after surgery respectively. Optometry were performed at 90 days after surgery. The χ(2) test was used to analyze the sex of the patients, and the age of the patients was analyzed by one-way ANOVA. Partial data in eye tests and in OSDI does not meet the normal distribution. Therefore, they were analyzed by Kruskal-Wallis H test. If significant difference existed, these data were then analyzed by independent sample Wilcoxon rank sum test. Results: Twelve patients were lost to visit within 3 months. A total of 90 patients were followed up for 90 days. The mean age of all patients was (69.5±9.5) years (46.0-89.0 years), 38 males and 64 females. There were 30 patients in Group A, group B and group C respectively. The prevalence of dry eye was 56. 7% (60/102). There was no significant difference among the three groups (P>0.05). OSDI questionnaire showed that OSDI score was significantly different among the three groups at 7, 30 and 90 days after operation (H=9.89, 55.53, 45.43, P<0.05). At 30 and 90 days after operation, the median OSDI scores were 12.50 and 10.42 in group C, respectively, which were better than those of group A scores 27.09 and 20. 8 (Z=- 6.30, -5.94, P<0.05), and were better than those of group B scores 17.71 and 13. 54 (Z=-3.40, -3.52, P<0.05). At 90 days after operation, the median BUT of B and C treatment groups was 9. 00, which was better than that of group A (4.00). The difference was statistically significant (H=21.51, P<0.05), There was no significant difference between group B and group C (Z=-0.34, P>0.05). Conclusion: The treatment of artificial tears with lipid composition in the early stage after phacoemulsification is beneficial to the improvement of postoperative symptoms and signs of dry eye.

Abstract
Objective: To study the relationship between bronchial asthma and smoking status in Chinese people. Methods: Asthma epidemiological survey and stratified-cluster-random method survey were performed in residents over 14 years in 8 provinces (cities) of China from February 2010 to August 2012. Asthma was diagnosed based upon case history, clinical signs and lung function test. Smoking status was investigated by questionnaire. Results: Sampling population was 180 099 and 164 215 were valid. A total of 2 034 subjects were diagnosed as asthma including 79 692 men and 84 523 women. The overall prevalence rate of asthma was 1.24% (2 034/164 215). Smokers were 23.8% (39 137/164 215) in the whole population. Smokers were 34.5% (702/2 034) in asthmatic patients, compared with 23.7% (38 435/162 181) in no-asthmatic population. The incidence of asthma was 1.79% and 1.06% in smokers and non-smokers respectively (P<0.001), suggesting that OR of smoking was 1.70 (95% CI 1.55-1.86, P<0.001). According to asthma control test (ACT) score, the level of asthma control in non smoking group was higher than that in smoking group(43.2% vs 35.3%). The times of hospitalization due to acute exacerbations(0.51 vs 0.41 events/person/year), total hospitalization rate(27.35% vs 20.12%), annual emergency room visits (0.80 vs 0.60 events/person/year) and emergency room visit rate (31.77% vs 24.47%) were all much higher in smoking asthmatic patients than those in non smoking asthmatic patients, indicating that the level of asthma control in smoking patients was significantly worse than in non smoking patients. Conclusions: The smoking rate in Chinese people over 14 years is still high. The prevalence rate of asthma in smokers is significantly higher than that of non-smokers. The level of asthma control in smokers is significantly worse than that in non smokers.

Abstract
Objective: To assess the long-term effectiveness of the transvaginal high uterosacral ligament suspension (HUS) in women suffering from advanced pelvic organ prolapse (POP). Methods: A retrospective review of records identified 118 women who underwent transvaginal HUS with or without additional concomitant anterior and (or) posterior repairs from June 2003 to August 2009 in the First Affiliated Hospital, General Hospital of People's Liberation Army. Of 118 women, 104 women completed the follow-up during study period; these 104 women were analysed. Follow-up visits were performed 2, 6 and 12 months after surgery and then annually. Anatomic results of POP was established by pelvic examination using pelvic organ prolapse quantitation system (POP-Q) staging. Funtional results were obtained by patient global impression of improvement (PGI-I), pelvic floor distress inventory-short form 20 (PFDI-20) and pelvic floor impact questionnaire short form (PFIQ-7). Surgical success required the fulfillment of all 3 criteria: (1) prolapse leading edge of 0 cm or less and apex of 1/2 total vaginal length or less; (2) the absence of pelvic organ prolapse symptoms as reported on the PFDI-20 question No. 3 ( "Do you usually have a bulge or something falling out that you can see or feel in your vaginal area?" ); and (3) no prolapse reoperations or pessary use during the study period. Results: The mean follow-up time was (9.1±1.5) years. The overall surgery success rate was 91.3% (95/104) according to above all 3 criteria. Prolapse recurrence rates were isolated anterior 6.7% (7/104), isolated apical 0, isolated posterior 2.9% (3/104) and multiple compartments 1.0% (1/104). Five women (4.8%, 5/104) developed bothersome vaginal bulge symptoms. None of recurrent women underwent retreatment, including either surgery or use of a pessary at last follow-up. The subjective satisfaction rate was 90.4% (94/104). PFDI-20 and PFIQ-7 scores showed a statistically significant improvement from preoperative 72 and 65 points to postoperative 17 and 9 points respectively (all P<0.01). There was a 2.9% (3/104) rate of intraoperative ureteral kinking and 3.8% (4/104) rate of postoperative morbidity. Conclusions: The transvaginal HUS for vault prolapse offers good long-term anatomical results with excellent vault suspension. With additional concomitant anterior and (or) posterior repairs, it will be a reconstructive surgery for the majority of advanced POP. It is minimal traumatic and appropriate for different type of POP, especially for the eldly patients. It is worthy of being popularized for clinical application.

Abstract
Objective: To analyze the prevalence of severe asthmain China. Methods: The epidemiological data was collected from 2 034 asthmatics who were diagnosed in the last epidemiological survey from 2009 to 2010 in 8 provinces. Results: According to the questionnaire survey, among the 2 034 patients, the previously diagnosed patients accounted for 72.47% (1 474/2 034) and the percentage of newly-diagnosed patients was 27.53% (560/2 034). In those 1 474 previously diagnosed asthmatics, 122 (8.28%) were classified into severe asthma, while 6.00% (122/2 034) of all asthmatics and 0.07% (122/164 215) of total respondents presented as severe cases. Statistically, there was no difference in the prevalence of severe patients between men and women. The morbidity rate of severe asthma was the lowest in the 21-30 year old group and the highest in 61-70 year old group (0.85% and 8.31% respectively). The difference among ages was statistically significant (χ2=18.791, P=0.005). In addition, the prevalence rates of severe asthma were also significantly diverged among patients with different education background(χ2=24.639, P<0.000 1). A negative relation was found between education level and the proportion of severe cases. Moreover, the morbidity of severe asthma in smoking patients and non-smoking patients were significantly different as well (χ2=7.447, P<0.05). Compared with asthma patients who do not smoke, smokers were more likely to suffer severe asthma (OR=1.663, 95% CI 1.150-2.404). Conclusions: The prevalence rate of severe asthma in China is similar to that in other countries.Elderly patients have higher risk of severe asthma. Smoking is considered as a risk factor for severe asthma.

Abstract
Objective: Breast intraductal papillary tumors are clinically common diseases derived from the ducts. The aim of this study is to investigate the clinicopathological characteristics of intraductal papillary tumors and risk factors for carcinogenesis. Methods: The clinicopathological data of 674 patients with breast intraductal papillary tumors, who underwent surgery in the National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences from January 2010 to July 2015, were retrospectively analyzed. Results: The median follow-up time was 46 months. The 674 cases were classified into 547 intraductal papilloma, 88 cases of intraductal papillary carcinoma, 32 cases of intracystic papillary carcinoma, and 7 cases of solid papillary carcinoma of breast. After a median follow-up time of 46 months, 13 out of 547 (2.4%) intraductal papillomas had local recurrence in the original dissected quadrat, another 10 cases developed breast cancer in the original dissected quadrat. The 3-year recurrence-free survival rates in intraductal papilloma and intraductal papilloma accompanied with atypical ductal hyperplasia were 97.7% and 93.5%, respectively, the recurrence-free survival curves showed a significant difference (P=0.011). Multivariate analysis indicated that atypical ductal hyperplasia was a major prognostic factor affecting the recurrence-free survival of intraductal papilloma (RR=0.183, 95%CI=0.054 to 0.777, P=0.020). Four cases (3.1%) of intraductal papillary carcinoma had local recurrence. The logistic analysis showed that patient aged >45 years, clinical manifestations of a breast lump, maximum tumor diameter greater than 2 cm are possible clinical manifestation of malignant breast intraductal papillary tumors (RR=1.735, 95%CI=1.007-2.990, P=0.047; RR=2.849, 95%CI=1.207-6.711, P=0.017; RR=3.792, 95%CI=2.162-6.653, P<0.001). Conclusions: Intraductal papillary tumors have a certain recurrence rate. Age, clinical features and tumor size may be predictive factors of intraductal papillary carcinoma.

Abstract
OBJECTIVE To explore the feasibility, safety and clinical application value of sentinel lymph node biopsy(SLNB)in patients with breast cancer after local lumpectomy. METHODS Clinical data of 195 patients who previously received local lumpectomy from January 2005 to April 2015 were retrospectively analyzed. All the patients with pathologic stage T1-2N0M0 (T1-2N0M0) breast cancer underwent SLNB. Methylene blue, carbon nanoparticles suspension, technetium-99m-labeled dextran, or in combination were used in the SLNB. The interval from lumpectomy to SLNB was 1-91 days(mean, 18.3 days)and the maximum diameter of tumors before first operation was 0.2-4.5 cm (mean, 1.8 cm). RESULTS The sentinel lymph node was successfully found in all the cases and the detection rate was 100%. 42 patients received axillary lymph node dissection (ALND), 19 patients had pathologically positive sentinel lymph node, with an accuracy rate of 97.6%, sensitivity of 95.0%, false negative rate of 5.0%, and specificity of 100%, and the false positive rate was 0. Logistic regression analysis suggested that the age of patients was significantly associated with sentinel lymph node metastasis after local lumpectomy. CONCLUSIONS For early breast cancer and after breast tumor biopsy, the influence of local lumpectomy on detection rate and accuracy of sentinel lymph node is not significant. Sentinel lymph node biopsy with appropriately chosen tracing technique may still provide a high detection rate and accuracy.

Abstract
Aims: The multilineage differentiation potential of human umbilical cord mesenchymal stem cells (HUCMSCs) holds therapeutic promise for non-healing ulcers and tissue regeneration. The present study evaluated the effects of HUCMSC transplantation after angioplasty for treatment of diabetic foot. Methods: Included in the study were 53 patients (72 limbs) with severe symptoms of Fontaine II-IV diabetic foot accompanied by varying degrees of lower extremity arterial disease. The patients were randomly apportioned to a control group (25 patients; 38 limbs) or an experimental group (28 patients; 34 limbs). Patients of both groups received interventional treatment with angioplasty; those in the experimental group also received HUCMSCs by endovascular infusion and injection around the foot ulcer. Results: Within the 3-month follow-up, relative to patients in the control group, those in the experimental group experienced significantly greater and more stable improvements in skin temperature, ankle-brachial pressure index, transcutaneous oxygen tension, and claudication distance. Notably, 3 months after treatment a significant increase in neovessels, accompanied by complete or gradual ulcer healing, was shown in the experimental group. In addition, no serious complications or adverse reactions were associated with the treatment. Conclusion: Therefore, our results indicate that HUCMSC transplantation after angioplasty is a safe and effective clinical therapy for severe diabetic foot.

Abstract
MicroRNA-452 (miR-452) is dysregulated in some human malignancies, and is correlated with tumor progression. However, its expression and function in human colorectal cancer (CRC) remain unclear. The aim of our study was to explore the effects of miR-452 in CRC tumorigenesis and development. Using reverse transcription quantitative real-time polymerase chain reaction, we detected miR-452 expression in CRC cell lines and primary tumor tissues. We also examined the association between miR-452 expression and clinicopathological factors. We then investigated the effects of miR-452 on the biological behavior of CRC cells. miR-452 expression was significantly downregulated in CRC compared with the adjacent noncancerous tissues. A low level of miR-452 was associated with larger tumor size, deeper invasion depth, and advanced TNM stage. Multivariate Cox regression analysis identified decreased miR-452 expression as an independent factor predicting poor prognosis for CRC patients. In addition, in vitro functional analysis showed that overexpression of miR-452 in HCT116 cells reduced cell proliferation, promoted cell apoptosis, and inhibited cell invasion and migration. These findings indicate that miR-452acts as a tumor suppressor in CRC, and would serve as a novel molecular therapeutic agent for the treatment of the disease.

Abstract
Obesity has become one of the greatest public health concerns especially in China and obstructive sleep apnea-hypopnea syndrome (OSAHS) is prevalent among morbidly obese patients. Metabolic and bariatric surgery has been proved to be a typical multidisciplinary strategy for obese patients with OSAHS but no related bariatric surgical guideline for OSAHS was found by now. In this paper, we extend to share our preliminary single-center experiences in the multidisciplinary treatment of severe obese with OSAHS.

Abstract
UNLABELLED The aim of the study was to review patients characteristics, describe the exact anatomic locations and size of the endometriosis in the abdominal wall, and discuss the factors that may contribute to mesh use during abdominal wall endometriosis (AWE) resection. MATERIALS AND METHODS Patients diagnosed with AWE in their surgical scars from January 2008 to December 2014 were documented. Descriptive data was collected and analyzed. RESULTS A total of 95 patients with an age ranging from 26 to 48 years, with a mean age of 33.5 ?5.0 years at the time of excision were analyzed. The mean diameter of the mass was 3.25 cm in the present series with an average of 4.97 cm in the mesh group by ultrasound. A total of 18 patients had mesh therapy for fascia defect compared with 77 non-mesh therapy patients. The size of the lesions, the mean duration of symptoms for painful mass, and level of the serum CA125 were statistically different between mesh group and non-mesh group (p < 0.05). Cases of endometriosis lesions limited to the adipose layer had significant lower chance of using mesh (p < 0.05). However, adipose layer endometriosis lesions that had penetrated through the fascia layer and invaded into rectus abdominis muscle layer with/without peritoneum layer had significant higher chance of using mesh (p < 0.05). CONCLUSIONS The more common position for scar endometriosis may be in the adipose layer at the corner of the surgical scar. Mesh therapy should be considered before surgery when the diameter of the abdominal wall mass detected by ultrasound is more than five em and/or when the lesions invade into rectus abdominis muscle with/without peritoneum tissues from adipose and fascia layers.

Abstract
Successful spin injection into graphene makes it a competitive contender in the race to become a key material for quantum computation, or the spin-operation-based data processing and sensing. Engineering ferromagnetic metal (FM)/graphene heterojunctions is one of the most promising avenues to realise it, however, their interface magnetism remains an open question up to this day. In any proposed FM/graphene spintronic devices, the best opportunity for spin transport could only be achieved where no magnetic dead layer exists at the FM/graphene interface. Here we present a comprehensive study of the epitaxial Fe/graphene interface by means of X-ray magnetic circular dichroism (XMCD) and density functional theory (DFT) calculations. The experiment has been performed using a specially designed FM1/FM2/graphene structure that to a large extent restores the realistic case of the proposed graphene-based transistors. We have quantitatively observed a reduced but still sizable magnetic moments of the epitaxial Fe ML on graphene, which is well resembled by simulations and can be attributed to the strong hybridization between the Fe 3dz2 and the C 2pz orbitals and the sp-orbital-like behavior of the Fe 3d electrons due to the presence of graphene.

Abstract
A novel MICB allele, MICB*030, has been identified in a healthy Chinese individual of Mongol ethnicity residing in northern China by polymerase chain reaction sequence-based typing (PCR-SBT) and confirmed by cloning and sequencing. MICB*030 was linked to HLA-B*35. Aligned with MICB*005:02, MICB*030 has a nonsynonymous adenine substitution at nucleotide position 50 in exon 3, leading to amino acid change from serine to arginine at codon 102 of the mature MICB molecule.

Abstract
We conducted a case-control study to clarify the asso-ciations between inflammatory cytokine, including interleukin (IL)-1b, IL-6, IL-8, and IL-10, polymorphisms and risk of acute pancreatitis. Genotyping analyses of IL-1β+3954 C/T (rs1143634), IL-1β-511 C/T (rs16944), IL-6 -174 G/C (rs1800795), IL-6 -634 C/G (rs1800796), IL-8 -251T/A (rs4073), IL-10 -1082A/G (rs1800896), and IL-10 -819C/T (rs1800871) were conducted using polymerase chain reaction-restriction fragment length of polymorphism. Unconditional logistic regression analysis was utilized to assess the potential association be-tween genotype frequencies and risk of acute pancreatitis. Multivari-ate regression analyses showed that subjects carrying the IL-8 -251 AA genotype had a significantly increased risk of acute pancreatitis, with an adjusted odds ratio (95% confidence interval) of 1.55 (1.02-2.36). However, we found no significant association between IL-1β +3954 C/T, IL-1β -511 C/T, IL-6 -174 G/C, IL-6 -174 G/C, IL-6 -634 C/G, IL-10 -1082A/G, or IL-10 -819C/T polymorphisms and risk of acute pancreatitis. We found that the IL-8 -251T/A polymorphism was associated with a higher susceptibility to acute pancreatitis in a Chinese population.

Abstract
One of the most important uses of DNA markers is cultivar identification. However, no DNA fingerprint analysis strategy is available for making DNA markers helpful in practical plant cultivar identification, especially for the identification of a large number of cultivars. We developed a manual cultivar identification diagram strategy for efficient identification of plant cultivars, from which a cultivar identification diagram (CID) of genotyped plant individuals can be constructed manually. This CID could be used as a reference for quick identification of plant cultivars of interest. We used 11-mer RAPD primers to amplify DNA samples of 32 ornamental peach genotypes; all the cultivars were well distinguished by fingerprints from 6 primers. The utility of this CID was verified by identification of three randomly chosen groups of cultivars among the 32 ones that we selected. This CID generated will be useful for the identification of commercially important ornamental peach cultivars.

Abstract
OBJECTIVE To study the de novo symptoms and their impact on life quality in patients that underwent transvaginal reconstructive pelvic surgery (RPS) with polypropylene mesh. MATERIALS AND METHODS From May 2004 to March 2011, 114 severe pelvic organ prolapse (POP) patients with Stage III-IV by POP-Q system underwent RPS with polypropylene mesh. Patients completed pelvic floor distress inventory short form (PFDI-20) and pelvic floor impact questionnaire short form (PFIQ-7) preoperatively and repeated them at two and six months, and one year postoperatively. RESULTS Ninety-six (84%, 96/114), 85 (75%, 85/114), and 77 (68%, 77/114) patients, respectively, completed the questionnaires at two months, six months, and one year postoperatively. All patients had POP-Q staging scoring < or = I at one year after surgery. Nineteen (19.8%, 19/96) patients had mesh exposure at two and six months (7.8%, 6/77) at one year follow-up. Most vaginal and pelvic symptoms, urinary and obstructive defecation bothersome symptoms improved significantly at two months postoperatively and this improvement was maintained at the one year follow-up. Mean score of PFDI-20 and PFIQ-7 all improved significantly postoperatively at two and six months and at one year follow-up (p < 0.01). Fifty percent (48/96) of patients had postoperative de novo symptoms at the two months follow-up predominantly presented with bothersome vaginal discharge (35.4%, 34/96) and pelvic muscle symptoms (20.8%, 20/96). Patients with de novo symptoms had higher postoperative mean POPDI-6 and POPIQ-7 scores (p < 0.05) than those without at the two month follow-up, but no significant difference was seen at the six month and at one year follow-ups. Patients with bothersome vaginal discharge had higher vaginal mesh exposure rate (41.2%, 14/34) than patients without (8.1%, 5/62) (p = 0.0003). One year after operation, 77 (68%) patients completed the non-validated satisfaction questionnaire. Seventy-four (96%, 74/77) patients said that they were either 'very satisfied' or 'satisfied' with the outcome of their surgery, while three (4%, 3/77) reported unsatisfactory results. CONCLUSIONS De novo symptoms were common after transvaginal RPS with polypropylene mesh, but most of them were moderate and resolved within six months postoperatively and seldomly had a long-term negative impact on their quality of life. The impact of dyspareunia on patients' sexual function requires further research.
