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
Presently, knowledge on the partitioning of polybrominated biphenyl ethers (PBDEs) from mother to fetus and the relationship between PBDE exposure and the levels of thyroid hormones (THs) needs to be extended further. In the present study, we investigated the concentrations of PBDEs in paired mother-fetus samples from 72 pregnant women in Wenling, China. The detection of PBDE concentration suggested that the expectant women living in Wenling for over 20 years might be highly exposed to PBDEs, which is largely ascribed to e-waste recycling activities in the local environment. The median concentration ratios between paired cord serum and maternal serum for higher-brominated BDEs were smaller than those for lower-brominated BDEs (p < 0.05). This result indicated that the placenta could hinder the transfer of PBDEs from mother to fetus, and the hindrance effect increased with higher-brominated congeners. Median ratios of paired placenta vs. maternal serum concentrations varied in a narrow range (0.15-0.25), with significantly lower value for BDE-209 than that for BDE-28 (p < 0.01). The extent of transplacental transfer was larger than that of placental retention for eight BDE congeners (p < 0.01). The concentration of BDE congeners among the paired samples could be fitted by equations, implying that their distribution could be predicted for each other (p < 0.001). There was a significant association between BDE-153 and TT4 levels in maternal serum from Wenling local residents (p < 0.05), suggesting potential implications for fetal development and their mothers' health in e-waste recycling environment. In addition, it was found that the relationship between BDEs and TH levels was likely affected by the exposure duration of the population to PBDEs.

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.
