Abstract
Objective: To evaluate the accuracy of the clinical staging by comparing preoperative clinical stage and pathological stage in gastric cancer patients, and to explore the potential beneficial population of neoadjuvant chemotherapy for gastric cancer. Methods: We retrospectively collected the clinical data of consecutive patients with gastric cancer who met the inclusion criteria (gastric adenocarcinoma, undergoing laparoscopic or open D2 radical operation, definite cTNM and pTNM) for admission of the Gastrointestinal Center of Peking University Cancer Hospital from July 2013 to April 2019. Patients with the number of harvested lymph nodes less than 16, history of gastric operation or preoperative radiochemotherapy were excluded. Preoperative clinical stage was obtained from abdominal and pelvic enhanced CT by radiologists, and postoperative pathological stage was derived from postoperative pathology reports. The concordance rate between preoperative clinical stage and postoperative pathological stage, and the proportion of pathological stage I in patients with specific preoperative clinical TNM stage were analyzed and compared. The potential beneficial population of neoadjuvant chemotherapy were considered as pI < 5%. Relationship between clinical features and concordance rate of stage was further analysed. Results: A total of 459 patients were included in the analysis, including 321 males and 138 females with mean age of 60 (23 to 85) years old. The concordance rate from T1 to T4 between preoperative clinical T staging and postoperative pathological T staging was 82.5% (33/40), 31.1% (28/90), 34.4% (62/180), and 55.0% (96/149), respectively. The concordance rate from N0 to N3 between preoperative clinical N staging and postoperative pathological N staging was 58.8% (134/228), 22.1% (19/86), 23.6% (26/110), and 54.3% (19/35), respectively. The sensitivity and specificity of abdominal enhanced CT in the diagnosis of lymph node metastasis were 64.5% (171/265) and 69.1% (134/194) respectively. The clinical stage of cT3/T4 patients with pathological stage I was 9.1% (30/329), and the sensitivity of corresponding pathological stage III was 94.8% (164/173), while the cT3/4+cN1-3 patients with pathological stage I stage was 1.4% (3/218), and the sensitivity of corresponding pathological phase III was 76.9% (133/173). Tumor location was associated with the concordance of cT/pT staging [gastroesophageal junction: 64 (56.6%), upper stomach: 9 (9/17), middle stomach: 31 (40.3%), lower stomach: 97 (39.9%), whole stomach: 4(4/9), χ(2)=9.845, P=0.043]; the degree of tumor differentiation was associated with the concordance of cN/pN staging [poorly differentiated: 94 (42.3%), moderated differentiated: 92 (41.1%), well differentiated: 12 (12/13), χ(2)=13.261, P=0.001], whose differences were statistically significant (all P<0.05). Conclusion: Based on a single-center retrospective data from Peking University Cancer Hospital, we think that the potential beneficial population of neoadjuvant chemotherapy for gastric cancer are those clinically staged as cT3/4+N1-3.

Abstract
Objective: To assess the clinical value of neutrophil-to-lymphocyte ratio (NLR) in predicting anastomotic leak of postoperative rectal cancer patients. Methods: The clinical data of 787 rectal cancer patients who underwent anterior resection from January 2014 to December 2017 in Affiliated Tumor Hospital of Zhengzhou University were collected. The postoperative numbers of white blood cell (WBS) on postoperative day (POD)1, 3 and 5 were detected, and the NLR was calculated. The relationship of NLR and the incidence of anastomotic leak was analyzed, and the area under the receiver-operating characteristic (ROC) curves was calculated. The accuracy of postoperative NLR in predicting the incidence of anastomotic leak was evaluated. Results: WBC counts of patients with leak on POD1, POD3 and POD5 were 13.2×10(9)/L, 9.1×10(9)/L and 8.9×10(9)/L, respectively, while those of patients without leak were 12.9×10(9)/L, 9.0×10(9)/L and 8.8×10(9)/L. The WBC count was not significantly different between patients with or without leak (P>0.05). The average NLR values of patients with or without leak were 13.3 and 11.6 on POD1, 10.9 and 7.6 on POD3, 9.3 and 5.3 on POD5, respectively. The NLR values of patients with leak on POD3 and POD5 were significantly higher than those of patients without leak (P<0.05). The cutoff value of NLR on POD3 was 8.6, the sensitivity and specificity of detecting the leakage was 73.2% and 75.6%, respectively, and the area under curve (AUC) was 0.744. The cutoff value of NLR on POD5 was 5.5, the sensitivity and specificity was 69.6% and 75.5%, the AUC was 0.726. The multivariate analysis result showed that NLR >8.6 was an independent factor for anastomotic leak prediction. Conclusion: Postoperative NLR on day 3 is useful in predicting anastomotic leak and can decrease the incidence of complication in rectal cancer patients who underwent anterior resection.

Abstract
BACKGROUND AND AIMS The unique anatomical and physiological function of the perineum region makes it difficult to be repaired after tumor resection. We aim to evaluate the efficacy of PSC divisional reconstruction strategy in the reconstruction of perineal skin defect. MATERIALS AND METHODS This study includes patients undergoing perineal skin defect reconstruction with PSC strategy-P (penis), S (scrotum), C (circum-penoscrotal skin) divisional reconstruction strategy. RESULTS From August 2013 to August 2018, 47 patients were enrolled in the surgical procedure. The defect area after resection measured 2 cm × 2.5 cm, minimum, and 12 cm × 18 cm, maximum. Among them, the cases involved one, two, and three zones are 12, 10, and 25, respectively. The skin defects were divisionally repaired. All flaps were well survived without complications or scar contracture. No tumor recurrence happened. CONCLUSION The application of PSC divisional reconstruction strategy is a promising way to repair wounds in circum-penoscrotal skin area. Moreover, this strategy is easy to process and shows no significant complications during follow-up period.

Abstract
OBJECTIVES To evaluate the negative effect of physical restraint use on the hospital outcomes of older patients. DESIGN A retrospective cohort study. SETTING Internal medicine wards of a tertiary medical center in Taiwan. PARTICIPANTS Subjects aged 65 years and over who were admitted during April to Dec 2017 were recruited for study. MEASUREMENTS Demographic data, geriatric assessments (polypharmacy, visual impairment, hearing impairment, activities of daily living before and after admission, risk of pressure sores, change in consciousness level, mood condition, history of falls in the previous year, risk of malnutrition and pain) and hospital conditions (admission route, department of admission, length of hospital stay and mortality) were collected for analysis. RESULTS Overall, 4,352 participants (mean age 78.7±8.7 years, 60.2% = male) were enrolled and 8.3% had physical restraint. Results of multivariate logistic regression showed that subjects with physical restraints were at greater risk of functional decline (adjusted odds ratio 2.136, 95% confidence interval 1.322-3.451, p=0.002), longer hospital stays (adjusted odds ratio 5.360, 95% confidence interval 3.627-7.923, p<0.001) and mortality (adjusted odds ratio 4.472, 95% confidence interval 2.794-7.160, p<0.001) after adjustment for covariates. CONCLUSION The use of physical restraints during hospitalization increased the risk of adverse hospital outcomes, such as functional decline, longer length of hospital stay and mortality.

Abstract
This study was conducted to determine the effects of residual superdoses of phytase on growth performance, tibia mineralization, and relative organ weight in ducks fed phosphorus-deficient diets. In Exp. 1, 4 kinds of commercial phytase were used to determine retention rate of phyatse with the phytase C being the highest via both high water-bath temperature (90%) and pelleting (50%), followed by phytase A, B, and D. In Exp. 2, a total of 560 male ducks were blocked based on body weight, and then allocated randomly to 7 treatments (5 replicates with 16 birds per replicate). Treatments included a maize-soybean meal-based diet with recommended calcium and 4.0 g non-phytate phosphorus (nPP)/kg starter diet or 3.8 g nPP/kg grower diet (positive control; PC), an nPP-deficient diet with 1.3 g nPP/kg starter diet or 1.1 g nPP/kg grower diet (negative control; NC), NC diets with increasing levels of residual phytase C (500, 1,000, 2,000, 3,000, and 4,000 units/kg feed) after pelleting. Birds fed NC diets had lower (P < 0.05) average daily gain (ADG) and average daily feed intake (ADFI) throughout the experiment compared with those fed PC diet. Supplementing NC diet with increasing residual superdoses of phytase improved (P < 0.05) ADG and ADFI quadratically in the entire experiment, while reduced feed-to-gain ratio (P < 0.05) quadratically during day 0 to 14. On day 14 and 35, birds fed NC diet had lower (P < 0.05) tibia length, weight, ash, calcium, phosphorus, and manganese contents than those fed PC diet. Increasing residual superdoses of phytase in NC diet increased (P < 0.05) tibia weight and ash, calcium, phosphorus contents quadratically on day 14 and 35. NC treatment increased (P < 0.05) the duodenum, jejunum, ileum, and cecum index compared with other treatments on day 14 and 35. Taken together, feeding increasing residual superdoses of phytase could counteract or exceed the negative effects of NC diet on growth performance, tibia mineralization, and relative organ weight in ducks.

Abstract
Objective: To explore the feasibility of assessing complications registration through medical information. Methods: A descriptive case series study was performed to retrospectively collect medical information and complication registration information of gastric cancer patients at Department of Gastrointestinal Cancer Center Ward I, Peking University Cancer Hospital from November 1, 2016 to March 1, 2017 (the first period), and from November 1, 2018 to March 1, 2019 (the second period). Case inclusion criteria: (1) adenocarcinoma confirmed by gastroscopy and biopsy; (2) patients undergoing open surgery or laparoscopic radical gastrectomy; (3) complete postoperative medical information and complication information. Patients who were directly transferred to ICU after surgery and underwent emergency surgery were excluded. Because difference of the complication registration procedure at our department existed before and after 2018, so the above two periods were selected to be used for analysis on enrolled patients. The prescription information during hospitalization, including nursing, medication, laboratory examination, transference, surgical advice, etc. were compared with the current Standard Operating Procedure (SOP, including preoperative routine examinations, inspection, perioperative preventive antibiotic use, postoperative observational tests, inspection, routine nutritional support, prophylactic anticoagulation, and prophylactic inhibition of pancreatic enzymes, etc.) for gastric cancer at our department. Medical order beyond SOP was defined as medical order variation. Postoperative complication was diagnosed using the Clavien-Dindo classification criteria, which was divided into I, II, IIIa, IIIb, IVa, IVb, and V. Medical order variation and complication registration information were compared between the two periods, including consistence between medical order variation and complication registration, missing report, underestimation or overestimation of medical order variation, and registration rate of medical order variation [registration rate = (total number of patients-number of missing report patients)/total number of patients], severe complications (Clavien-Dindo classification ≥ III), medical order variation deviating from SOP and the corresponding inferred grading of complication. The data was organized using Microsoft Office Excel 2010. Results: A total of 177 gastric cancer patients were included in the analysis. The first period group and the second period group comprised 89 and 88 cases, respectively. The registrated complication rate was 23.6% (21/89) and 36.4% (32/88), and the incidence of severe complication was 2.2% (2/89) and 4.5% (4/88) in the first and the second period, respectively. The complication rate inferred from medical order variation was 74.2% (66/89) and 78.4% (69/88), and the incidence of severe complication was 7.9% (7/89) and 4.5% (4/88) in the first and second period, respectively. In the first and second period, the proportions of medical order variation in accordance with registered complication were 36.0% and 45.5% respectively; the proportion of underestimation, overestimation and missing report were 5.6% and 4.5%, 4.5% and 4.5%, 53.9% and 45.5%, respectively; the registration rate of medical order variation was 46.1% and 54.5%; the number of case with grade I complications inferred from medical order variation was 34 (38.2%) and 25 (28.4%), respectively; and the number of grade II was 12 (13.5%) and 15 cases (17.0%), respectively. The reason of the missing report of medical order variation corresponding to grade I complication was mainly the single use of analgesic drugs outside SOP, accounting for 76.5% (26/34) and 64.0% (16/25) in the first and second period respectively, and that corresponding to grade II complication was mainly the use of non-prophylactic antibiotics, accounting for 9/12 cases and 5/15 cases, respectively. Conclusions: Medical information can evaluate the morbidity of complication feasibly and effectively. Attention should be paid to routine registration to avoid specific missing report.

Abstract
Objective: Using data of health information system (HIS) of medical institutions to study the incidence and hospitalization of herpes zoster in three districts of Beijing. Methods: According to the different level of economic development and geographical features in Beijing, 3 districts of Xicheng, Changping and Miyun were chosen and all 110 medical institutions of the first level and above in the 3 districts are included in the survey. All the outpatient and inpatient herpes zoster cases in 2015 were retrospectively reviewed by HIS system. After distinguishing the reduplicated cases, Using the first outpatient case as a molecule and the resident population as denominator to estimate the annual incidence rate, as well as the annual hospitalization rate was estimated based on primary diagnostic hospitalized cases as molecule and the resident population as denominator. Results: A total of 32 313 primary visit outpatient cases were investigated, of which 18 360 cases (56.8%) were women and 20 923 cases (64.8%) were ≥50 years old. The overall estimated incidence of the 3 districts was 8.8‰ with an increase trends with age and reached to the highest in ≥80 years old (30.5/1 000). The incidence of Xicheng, Changping and Miyun districts are respectively 16.2‰, 4.0‰ and 5.7‰. A total of 701 primary visit inpatient cases were identified, of which 366 cases (52.2%) were women and 651 cases (92.9%) were ≥50 years old. The estimated annual hospitalization rate was 19.4/100 000, with the primary and secondary diagnostic hospitalization rate are respectively 5.9/100 000 (212 cases) and 13.5/100 000 (489 cases). The disease types of secondary diagnostic inpatient herpes zoster cases were as follows: cardiovascular disease (19.0%, 93 cases), stroke (14.5%, 71 cases), pneumonia/chronic obstructive pulmonary disease (14.1%, 69 cases), tumor (12.5%, 61 cases) and diabetes (5.7%, 28 cases). Conclusion: Most of the herpes zoster cases in Beijing are over 50 years old, and the incidence of female is slightly higher than male. This disease should become a public health issue of great concern.

Abstract
Objective: To investigate the clinical, pathological and CT features associated with the effective mutation of epidermal growth factor receptor (EGFR) in multiple primary lung cancers (MPLCs) , and to determine the target population of EGFR mutations tests. Methods: A total of 558 nodules from 232 patients with MPLCs who underwent surgery in the Cancer Hospital of Chinese Academy of Medical Sciences from August 2017 to December 2017 were selected. Two hundreds and sixteen nodules were detected by DNA direct sequencing. Chi-square test and Mann-Whitney U test were used to compare the clinical, pathological and CT features of 216 nodules in the EGFR effective mutation group and the non-effective mutation group. Logistic regression analysis was used to explore the independent risk factors of EGFR mutation. The cut off value was determined using the receiver operating characteristic(ROC) curve. Of 232 cases 558 nodules of surgically resected MPLCs, EGFR mutation of 216 nodules was determined by direct DNA sequencing. Results: There were 58 males and 174 females with MPLCs(male︰female=1︰3). There were 117 cases of age ≥59 years old and 115 cases of age <59 years old. There were 192 non-smokers, accounting for 82.8% of all patients. There were 2-7 nodules in the patient's lungs, of which 170 patients had two nodules in the lungs, 44 patients had 3 nodules, and another patient had 7 nodules. Among them, 216 nodules were detected by EGFR gene, 136 were effective mutations, and 80 were non-effective mutations (including wild type and null mutation). EGFR effective mutation group and non-effective mutation group were statistically significant in lung adenocarcinoma patients with different gender, age, smoking history, histological type, and differentiation degree (P=0.006, 0.002, 0.002, 0.015, 0.025).Among them, the effective mutation group were 107 females, 85 cases≥ 59 years old, 117 cases with no smoking history, 68 acinar-based, 89 moderate differentiation. In the count data, 127 nodule edges were lobed, and only 9 nodule edges were smooth. Among the measurement data, the GGO CT value was approximately (-459±147) HU in the EGFR mutation group, with statistical difference (P=0.037). The GGO diameter was approximately (11±9)mm,P=0.279.Multivariate Logistic regression analysis showed that GGO diameter (OR=0.873, 95%CI: 0.780-0.997; P=0.018) and smooth margins (OR=0.183,95%CI: 0.041-0.824; P=0.027) were independent protective factors of effective mutations of EGFR. Conclusions: In MPLCs, effective EGFR mutation is more common, and associated with elder female, age≥59 years, non-smoking, GGO attenuation <-548 HU, moderately differentiated, predominant invasive papillary adenocarcinoma. Patients with MPLCs and these risk factors may be encouraged to have postoperative EGFR molecular test.

Abstract
Objective: To describe the clinicopathological features of conjunctival actinic keratosis (AK) and relation to the infection of human papillomavirus (HPV). Method: Retrospective case series study. Eighteen cases (18 eyes) of conjunctival AK were obtained in Tianjin Eye Hospital and Institute (2005-2018). The clinical and histopathological features were studied. HPV was detected by a modified general primer HPV polymerase chain reaction (PCR) system in all formalin-fixed, paraffin-embedded specimens. Results: The male to female ratio was 5∶1. The mean age at diagnosis was 60 years (range: 43-79 years). Sixteen cases were located in the nasal interpalpebral region, and two cases were located in the temporal interpalpebral region. All cases were located in corneal limbus, and the mean distance of corneal invasion was 2 mm (range, 1-4 mm). The mean diameter was 4.6 mm (range, 2.0-8.0 mm). Clinically, most lesions (16 cases) appeared as a white or milky, flat plaque with clear borderline and conjunctival hyperemia; a few lesions (2 cases) showed a brown-black mass, partially white. Pathologically, conjunctival AK was a proliferation of epithelium with prominent parakeratosis or hyperkeratosis, stratum spinosm thickening and basal cell proliferation. Many AKs show solar elastosis and a mild inflammatory infiltrate of lymphocytes and plasma cells in the stroma. Most lesions (15 cases) were hypertrophic type, two cases were pigmented type, and one case was acantholytic type. HPV was negative in 18 cases. All case were removed by complete surgical excision. The rage of follow-up period was 1.0-10.4 years, ten cases were recorded, and no case recurred after surgical excision. Conclusions: Conjunctival AK is epithelial precancerous lesion that occurs in the keratoconjunctival margin. HPV infection might not be a causative factor in conjunctival AK.

Abstract
Objective: To analyze the risk factors of cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. Methods: 530 patients with esophageal cancer underwent thoracoscopic-lapacoscopic esophagectomy at the Cancer Hospital, Chinese Academy of Medical Sciences from Jan 2011 to Dec 2015. The demographic, surgical and clinical data of patients were retrospectively analyzed. Multivariate logistic regression was used to evaluate risk factors of cervical anastomotic leakage in these patients. Results: A total of 530 patients undergoing thoracoscopic-lapacoscopic esophagectomy were enrolled in this study. There were 421 males and 109 females. The mean age was (59.40±8.08) years old, and 91 patients with cervical anastomotic leakage. Sigle factor analysis revealed that the risk grading by American Society of Aneshesiologists, previous history of chest surgery, respiratory comorbidity, diffusion capacity for carbon monoxide of the lung, operation time, anastomosis, average days of postoperative hospitalization, death within 30 days after surgery, respiratory complications, pleural effusion or empyema, and poor healing of the incision were statistically associated with cervical anastomotic leakage (all P<0.05). Multivariate analysis showed that previous history of chest surgery, hepatic insufficiency, manual anastomosis, prolonged postoperative hospitalization, and poor healing of the incision were independent risk factors for cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy (all P<0.05). Conclusions: Previous history of chest surgery, hepatic insufficiency, poor healing of the incision, manual anastomosis and prolonged postoperative hospitalization were significantly associated with cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. It's important to strengthen perioperative nursing and surgical techniques to prevent anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.

Abstract
Optical chaos communication has advantages of high speed and long transmission distance. Unfortunately, the key space of the traditional transceiver, i.e. semiconductor laser with mirror feedback, is limited due to the time delay signature. In this paper, we propose and numerically demonstrate a key space enhancement by using semiconductor laser with optical feedback from a chirped fiber Bragg grating (FBG). The chirped FBG feedback can make feedback delay a key parameter by eliminating the time delay signature. Moreover, the grating dispersion and center frequency can also be used as new keys. As a result, the dimension of key space is increased. By taking a bidirectional communication scheme as an example, numerical results show that the key space is raised by 244 times as against mirror feedback with a data rate of 2.5 Gb/s and a coupling strength of 0.447. As the coupling strength decreases, the key space increases due to the fact that chaos synchronization becomes more sensitive to parameter mismatch.

Abstract
Objective: To evaluate the diagnostic efficiency of combination of CT multiplane 3D reconstruction (CT-3DR), radial endobronchial ultrasound (R-EBUS), and rapid on-site evaluation (ROSE) for peripheral solitary pulmonary nodules (SPN). Methods: A total of 176 patients with peripheral solitary pulmonary nodule were included from the Nanjing Chest Hospital from March 2016 to March 2017. According to different methods, all the patients were divided into four groups: EG (i.e. R-EBUS+Guiding sheath (GS))group, CTE (i.e. CT-3DR+R-EBUS) group, RE (i.e. ROSE+R-EBUS) group, and triad (i.e. CT-3DR+ROSE+R-EBUS) group. Sampling was performed by transbronchial lung biopsy. The diagnostic yield and complications, procedure time and influencing factors in these four groups were retrospectively analyzed. The value of ROSE and combination of CT-3DR+ROSE+R-EBUS in diagnosis for SPN also was evaluated. Results: The diagnostic yield for total SPNs among four groups were 70.5% in EG group, 70.0% in CTE group, 69.0% in RE group and 74.0% in triad group, respectively. There was no significant difference among four groups (all P>0.05). The procedure time of EG group, CTE group, RE group and triad group were (34.0±6.3), (26.6±6.8), (27.2±7.8) and (19.4±5.4) min, respectively. The procedure time was the shortest in triad group compared with the other three groups (all P<0.001) and the time of CTE and RE groups were significantly shorter than the EG group (both P<0.001). The coincidence rates of CT-3DR navigation position with target bronchus were 87.5% in CTE group and 90.0% in triad group with no significant difference between these two groups (P>0.05). The diagnostic yield was higher for SPNs with their major diameter ≥2 cm than those with their major diameter<2 cm in all four groups (all P<0.05). The positive diagnostic yield was higher with ultrasonic probe located within SPN lesion than the probe adjacent to or deviated the lesion in all four groups (all P<0.05). In EG and RE groups, for those SPNs with the distance between the lesion and pleura≥2 cm, the diagnostic yield were higher than those withe the distance<2 cm (P<0.05) but no similar phenomenon was observed in CTE and triad groups. No significant correlation was detected between the diagnostic yield and the density of SPN lesions among four groups (all P>0.05). ROSE was used in RE and triad groups. The coincidence rate of ROSE with histopathology was 82.6% and the value of Kappa was 0.608. The diagnostic sensitivity, specificity, positive predictive value and negative predictive value of ROSE were 0.818, 0.846, 0.931 and 0.647, respectively. Conclusions: CT-3DR navigation and ROSE help to improve the diagnostic efficiency of R-EBUS for SPN. Combination of CT-3DR, R-EBUS and ROSE is of diagnostic value for peripheral SPN and with significant shortening of procedure time.

Abstract
OBJECTIVES To determine whether nutritional status can predict 3-year cognitive and functional decline, as well as 4-year all-cause mortality in older adults. DESIGN Prospectively longitudinal cohort study. SETTING AND PARTICIPANTS The study recruited 354 men aged 65 years and older in the veteran's retirement community. MEASURES Baseline nutritional status was evaluated using the Mini-Nutritional Assessment-Short Form (MNA-SF). Cognitive function and Activities of Daily Living (ADL) function were determined by the Mini-Mental State Examination (MMSE) and the Barthel Index, respectively. Three-year cognitive and functional decline were respectively defined as a >3 point decrease in the MMSE scores and lower ADL scores than at baseline. Univariate and multivariable logistic regression analyses were conducted to identify nutritional status as a risk factor in poor outcome. The Kaplan-Meier method and Cox proportional regression models were used to estimate the effect of malnutrition risk on the mortality. RESULTS According to MNS-SF, the prevalence of risk of malnutrition was 53.1% (188/354). Multivariate logistic regression found risk of malnutrition significantly associated with 3-year cognitive decline (Adjusted odds ratio [OR] 2.07, 95% Confidence Interval [CI] 1.05-4.08, P =0.036) and functional decline (Adjusted OR 1.83, 95% CI 1.01-3.34, P =0.047) compared with normal nutritional status. The hazard ratio (HR) for all-cause mortality was 1.8 times higher in residents at risk of malnutrition (Adjusted HR 1.82, 95% CI 1.19-2.79, P =0.006). CONCLUSIONS Our results provide strong evidence that risk of malnutrition can predict not only cognitive and functional decline but also risk of all-cause mortality in older men living in a veteran retirement's community. Further longitudinal studies are needed to explore the causal relationship among nutrition, clinical outcomes, and the effect of an intervention for malnutrition.

Abstract
Objective: To evaluate Magnetic Resonance Imaging (MRI) at 3.0T in differential diagnosis of the origin of adenocarcinoma at the junction of the lower uterine segment and endocervix. Methods: 71 patients with adenocarcinoma at the junction of the lower uterine segment and endocervix were retrospectively collected. Pelvic MR examinations, including diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) sequences, were performed within 2 weeks before surgery. MR images were analyzed and measured by two radiologists, including the location of the tumor center, the enhancement pattern, the anterior and posterior diameters, the left and right diameters, the upper and lower diameters, and the apparent diffusion coefficient (ADC) of the tumor. Immunohistochemical method was used as gold standard in distinguishing cervical adenocarcinoma and uterine adenocarcinoma. Results: The upper and lower diameters of uterine adenocarcinoma were [(5.80±2.31) cm], significantly larger than those of cervical adenocarcinoma [(4.16±2.17) cm, P=0.009]. Using 4.5cm as the best cutoff point value, the sensitivity and specificity in distinguishing uterine adenocarcinoma and cervical adenocarcinoma were 68.4% and 65.4%, respectively. According to the location of tumor center, the sensitivity and specificity were 84.2% and 73.1%, respectively. Using tumor enhancement pattern as the criterion, the sensitivity and specificity of diagnosing uterine adenocarcinoma and cervical adenocarcinoma were 68.4% and 80.8% respectively. Conclusions: MRI has certain clinical value in evaluating the origin of adenocarcinoma at the junction of the lower uterine segment and endocervix. The lesions can be diagnosed according to the main location, the characteristics of dynamic enhancement and the growth pattern of the tumor.

Abstract
Objective:To investigate the expression and significance of CTHRC1 in patients with papillary thyroid cancinoma.Method:We collected 63 specimens of papillary thyroid carcinoma tissue with 36 specimens of the adjacent normal thyroid tissue and 23 specimens of thyroid nodular goiter. The expressions of CTHRC1 protein in these tissues were detected by immunohistochemical staining. The correlations between the expressions of CTHRC1 with clinicopathologic features,E-cadherin and Vimentin expression were analyzed.Result:CTHRC1 protein expression levels in papillary thyroid carcinoma tissue were significantly higher than those in adjacent normal thyroid tissue and benign disease(P<0.01);CTHRC1 expression was significantly correlated with lymph node metastases(P<0.05). Moreover,CTHRC1 expression was correlated with the expression of E-cadherin and Vimentin(P<0.01).Conclusion:CTHRC1 is related with the occurrence and miligant transformation of papillary thyroid cancinoma. We speculated that CTHRC1 might play a role in the epithelial-mesenchymal transition of papillary thyroid cancinoma.

Abstract
Objective: To investigate the effect of α7nAChR mediated cholinergic anti-inflammatory pathway on inhibition of atrial fibrillation by low-level vagus nerve stimulation(LL-VNS). Methods: Eighteen beagles were randomized into control group (n=6), LL-VNS group (n=6) and methyllycaconitine (MLA) + LL-VNS group (n=6). All the beagles were subjected to rapid atrial pacing at 800 beats/min for 6 hours.And the effective refractory period (ERP) of atriums and pulmonary veins and induced atrial fibrillation (AF) were measured hourly during non-pacing.After cessation of pacing for 3 hours, the beagles in control group were injected with saline into four ganglionated plexis (GPs), the beagles in LL-VNS group were given LL-VNS and saline injected into four GPs, and the beagles in MLA+ LL-VNS group were injected with MLA into four GPs combined with LL-VNS.And the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and acetylcholine (ACh) in the plasma at baseline condition, 3 h and 6 h were measured.At the end of this experiment, atrial tissues were collected to examine the levels of TNF-α, IL-6, ACh, NF-κBp65 and STAT3 proteins. Results: During the right atrium pacing for the first 3 hours, the ERPs were gradually decreased while AF inducibility were gradually increased in all groups. At the end of this experiment, compared with the control group and MLA+ LL-VNS group, the ERPs in LL-VNS group were increased, and the induced times and duration of AF were significantly decreased. The levels of TNF-α and IL-6 in plasma were all significantly decreased in LL-VNS group and MLA+ LL-VNS group when compared with the control group(pg/ml) [IL-6: (101±6) vs (119±7), P<0.05; (102±5) vs (119±7), P<0.05; TNF-α: (17.8±1.7) vs (22.1±2.0), P<0.05; (17.9±2.2) vs (22.1±2.0), P<0.05]. And the levels of ACh were higher than in the control group(μg/ml)[(151±13) vs (123±10), P<0.05; (145±5) vs (123±10), P<0.05]. After cessation of pacing for 6 hours, compared with the control groupand MLA+ LL-VNS group, the tissue levels of TNF-α and IL-6 were significantly decreased in LL-VNS group (P<0.05). The concentrations of NF-κBp65 proteins in atrial tissues were lower in the LL-VNS group (P<0.05), and the levels of STAT3 proteins in those tissues were higher in the LL-VNS group than in thein the two other groups (P<0.05). Conclusion: LL-VNS could inhibit the atrial electrical remodeling and atrial fibrillation induction; cholinergic anti-inflammatory pathway mediated by α7nAChR may be the important mechanism in vagal nerve regulated AF.

Abstract
Objective: To evaluate the application value of intravoxel incoherent motion (IVIM) and diffusion tensor imaging (DTI) in detecting early-stage diabetic nephropathy and to assess the damage of ralated renal function. Methods: A total of 52 patients with type 2 diabetes diagnosed in Zhongda Hospital were collected from April 2016 to May 2017 and were assigned to DM group (diabetes without nephropathy, n=32) and DN group (diabetes with nephropathy, n=20) according to detection of microalbuminuria, a cohort of healthy recipients were included as control group (n=27) in the meantime. All of the subjects underwent IVIM and DTI examination. The cortical and medullary parameters[IVIM: perfusion fraction f, tissue diffusivity D, pseudodiffuvisity D(*;) DTI: fractional anisotropy FA, apparent diffusion coefficient ADC, principal diffusivities (λ1, λ2, λ3)]were obtained respectively and were compared among groups. The relationship between MRI related parameters and estimated glomerular filtration rate (eGFR) were statistically investigated; and diagnostic performance of IVIM and DTI in discriminating DM and DN group was evaluated by receiver operating characteristic analysis. Results: The cortical and medullary f, D values in DN group were lower than those in DM group and control group (F=17.32, 15.69, 6.71, 10.94, all P<0.05). D values of all subjects showed positive correlations with eGFR (cortex r=0.518, medulla r=0.538, both P<0.05). The diagnostic efficiency of cortical f values to discriminate diabetes and diabetic nephropathy was 0.817, the cut-off value was 0.205. The medullary FA value in DM group was lower than that in control group ((0.371±0.051 vs 0.423±0.043, t=4.188, P<0.05); and the medullary FA value in DN group (0.315±0.062) was lower than that in control and DM group (F=25.08, P<0.05). The medullary λ3 values in DM group and DN group were all significantly higher than that in control group (F=7.86, P<0.05). The diagnostic efficiency of medullary FA values to discriminate diabetes and diabetic nephropathy was 0.763, the cut-off value was 0.344. Conclusion: IVIM and DTI can reflect the abnormal perfusion and diffusion during early-stage diabetic nephropathy and have the potential value to assess the damage of ralated renal function.

Abstract
To investigate the expression of microRNA-34a (miR-34a) in patients with chronic lymphocytic leukemia (CLL) in Xinjiang Uygur and Han nationalities and its prognostic significance. Our data showed that miR-34a expression in Uygur and Han CLL patients was significantly higher than that in their respective healthy controls, while miR-34a levels were similar between Uygur and Han patients. By comparing with known prognostic factors, receiver operating characteristic (ROC) curves showed that miR-34a was a good predictive factor for the prognosis of CLL (demarcation value was 3.567 6). Survival analysis was further performed according to miR-34a expression level, that low expression of miR-34a translated into poor prognosis.

Abstract
BACKGROUND Presurgical hand washing is crucial for preventing surgical site infections (SSIs). Chlorhexidine gluconate (CHG) and povidone-iodine (PI) products have been conventionally used as hand scrubs for presurgical hand preparation. However, waterless hand rub (WHR) products have been developed for operating room staff. AIM The aim of this study was to conduct a systematic review and meta-analysis to compare the antiseptic efficacies of WHR, CHG, and PI in surgical settings. METHODS PubMed, Embase, and Cochrane Library databases as well as the ClinicalTrials.gov registry were searched for studies published before October 2018. Randomized controlled trials (RCTs) comparing the clinical outcomes of the use of WHRs, CHG, or PI for presurgical hand washing were included. A random effects model was used for meta-analysis. Colony-forming unit (cfu) counts, SSI rates, and preference and compliance were determined to measure efficacies. FINDINGS Eleven RCTs involving 5135 participants were included. Residual cfu counts were significantly lower in the WHR and CHG groups than in the PI group. The differences in cfu counts between the WHR and CHG groups were non-significant. No significant differences were observed in the SSI rates between the WHR and traditional hand scrub groups. Moreover, WHRs were considered most favourable and were associated with higher compliance rates than the other products. CONCLUSION WHRs and CHG exhibited higher antiseptic efficacies than PI. However, additional studies with consistent outcome measurements and accurate grouping are required to obtain comprehensive results. Moreover, preference, compliance, and the cost determine the selection of hand wash products.

Abstract
Objective: To explore the surgical results and clinicopathological features of gastric cancer patients with liver metastases. Methods: The clinicopathological data and post-operative survival of 37 patients who underwent resection of liver metastasis from gastric cancer at our department from Dec. 2007 to Dec. 2014 were analyzed. Results: The 1-, 3-, and 5-year overall survival rates after resection were 91.4%, 57.9%, and 22.0%, respectively, with a median survival of 37 months. Univariate analysis revealed that lymph node metastasis, multiple hepatic metastases and no preoperative chemotherapy are unfavorable prognostic factors for overall survival. Multivariate analysis identified that lymph node metastasis and number of liver metastasis are independent prognostic factors. Conclusions: Gastric cancer patients with a solitary liver metastasis may be good candidates for gastric D2 resection combined with liver R0 resection.

Abstract
Paclitaxel is used for the treatment of several types of cancers. However, one of its significant limiting complications is painful peripheral neuropathy during therapy. Gender is considered to play a role in modifying pain intensity. The present study examined the effects of female sex hormones on paclitaxel-induced neuropathic pain and the engagement of inflammatory signal of sensory nerves. Ovariectomies were performed on rats and subsequent hormone replacement with the combination of 17β-estradiol and progesterone was given. ELISA was used to determine the levels of proinflammatory cytokines (PICs) such as IL-1β, IL-6 and TNF-α in the dorsal root ganglion (DRG) of rats with different conditions of female sex hormones; moreover, Western blot analysis was used to examine expression of PIC receptors. The results of our study demonstrated that the increases of IL-1β, IL-6 and TNF-α; and expression of their respective receptors induced by paclitaxel were less in the DRG of ovariectomized rats with lack of female sex hormones. Thresholds of pain responses to mechanical and thermal stimuli appeared to be greater in ovariectomized rats with lack of female sex hormones. Overall, the findings indicate that circulating 17β-estradiol and progesterone contribute to the modulation of neuropathic pain response after administration of paclitaxel, likely via PIC signal in the sensory nerves, which is implicated to consider sex difference for pain management with application of chemotherapeutic paclitaxel.
