Abstract
Objective: To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy. Methods: This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0-1; and (7) ASA score I-III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores). Result: [1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10-1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4-13) days. The median time to postoperative oral intake was 7 (range, 2-14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3-18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457). Conclusion: Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.

Abstract
Objective: To explore the correlation between pulmonary quantitative CT measurement indicators and respiratory symptoms in patients with stable chronic obstructive pulmonary disease (COPD). Methods: A total of 186 patients with COPD in stable stage who visited in the outpatient department of Beijing Hospital from March 2021 to February 2022 were prospectively included. Demographic data, respiratory symptoms and lung function were collected. The original DICOM data of high-resolution CT (HRCT) were processed using the FACT medical imaging information system and the pulmonary emphysema index pixel index-950 (PI-950) and the airway wall thickness (4-6 T) and the percentage of airway area (4-6 WA%) of the 4-6 generation bronchi which represent the segmental and subsegmental bronchi were measured automatically. According to the modified British medical research council dyspnea scale (mMRC, 0-1 point for low score group, 2-4 points for high score group), chronic obstructive pulmonary disease assessment test (CAT, score<10 points for low score group,≥10 points for high score group), cough, expectoration and wheezing (asymptomatic group and symptomatic group), they were divided into two groups as dependent variables. The relationship between imaging parameters and the above symptoms was evaluated using a logistic regression model. Results: The study ultimately included 186 patients who met the inclusion criteria, including 162 males and 24 females, aged (68.9±9.3) years old. There were 83 patients in the high mMRC group, 120 patients in the high CAT group, 146 patients in the cough group, 154 patients in the expectoration group, and 65 patients in the wheezing group. The age and emphysema parameter PI-950 in the high score group of mMRC were higher than those in the low score group, while the percentage of the forced expiratory volume in 1 second (FEV1) predicted value (FEV1 pred) after medication, the percentage of carbon monoxide diffusion volume (DLCO) predicted value (DLCO pred), and the percentage of the maximum midexpiratory flow (MMEF) predicted value (MMEF pred) after medication were lower than those in the low score group (all P<0.05). The age of the high CAT group was higher than that of the low score group, while FEV1 pred and MMEF pred after medication were lower than those of the low score group (all P<0.05). The proportion of males, patients with smoking history, and smoking index in the cough group were higher than those in the non cough group, while the 4 WA% was lower than that in the non cough group (all P<0.05). The proportion of males, patients with smoking history, smoking index, and PI-950 in the expectoration group were higher than those in the non expectoration group, while FEV1 pred after medication and 4 WA% were lower than those in the non expectoration group (all P<0.05). The 5 WA% and 6 WA% of the wheezing group were higher than those of the non wheezing group, while MMEF pred after medication was lower than that of the non wheezing group (all P<0.05). Multivariate logistic regression analysis showed that after adjusting for demographic characteristics, smoking, combined diseases, lung function and other confounding factors, for every 10% increase in PI-950, the likelihood of developing more severe dyspnea for the patients (high score group according to mMRC) increased by 67.3% (OR=1.673, 95%CI: 1.052-2.658); Every 10% increase in 6WA% increased the likelihood of wheezing by 3.189 times (OR=4.189, 95%CI: 1.070-16.395). No correlation was found between various imaging indicators and cough, expectoration, and CAT scores (P>0.05). Conclusion: Quantitative CT measurement indicators in stable COPD patients can explain the presence and severity of respiratory symptoms, the pulmonary emphysema indicator is associated with dyspnea, and the percentage of proximal airway wall area is associated with wheezing.

Abstract
Objective: To analyze the clinical characteristics and complications of esophageal foreign bodies of button battery ingestion in children. Methods: A retrospective descriptive study included 83 children who were hospitalized in our hospital on account of button battery ingestion from January 2011 to December 2021. There were 50 males (60.2%) and 33 females (39.8%). The age ranged from 7.6 months to one month off 10 years, with a median age of 18 months. The data of patient demographics and time from ingestion to admission, location, symptoms, management, complications, and follow-up outcome were recorded. SPSS17.0 software was used for statistical analysis. Results: Seventy-two children (86.7%) were younger than 3 years old. The time from ingestion to admission ranged from 1 h to 2 months, with a median time of 8 h. Among the 63 children who were first diagnosed in our hospital, the most common clinical symptoms were nausea and vomiting (32 cases, 50.8%), dysphagia (31 cases, 49.2%), salivation (11 cases, 17.5%) and fever (10 cases, 15.9%). Seventy-three of 83 cases had complete preoperative diagnostic tests, and 55 cases (75.3%) were diagnosed by X-ray. In 56 cases (76.7%), the foreign badies were impacted in the upper third of esophagus. In 72 cases (86.7%), the foreign badies were removed by rigid esophagoscopy. 23 (27.7%) had serious complications, including tracheoesophageal fistula in 15 cases(TEF;65.2%), vocal cord paralysis (VCP;34.8%) in 8 cases, esophageal perforation in 3 cases (EP;13.0%), hemorrhage in 3 cases(13.0%), mediastinitis in 3 cases (13%), and periesophageal abscess in 1 case (4.3%). There were significant differences in the exposure time of foreign bodies and unwitnessed ingestion by guardians in the complications group (P<0.05). 2 cases died (2.4%)respectively due to arterial esophageal fistula bleeding and respiratory failure caused by stent displacement during the treatment of tracheoesophageal fistula. Conclusion: Accidental button battery ingestion can be life-threatening. and it mostly happens in children under 3 years old. Serious complications may happen cause of non-specific clinical manifestations and unwitnessed ingestions. Anterior and lateral chest X-ray is the first examination choice. Tracheoesophageal fistula is the most common serious complication.

Abstract
Objective: To examine the safety and effectiveness of inflatable video-assisted mediastinoscopic transhiatal esophagectomy (IVMTE). Methods: Totally 269 patients admitted to the Anhui Provincial Hospital of Anhui Medical University who underwent IVMTE (IVMTE group, n=47) or thoracoscopy combined with minimally invasive Mckeown esophageal cancer resection (MIME group, n=222) from September 2017 to December 2021 were analyzed retrospectively. There were 31 males and 16 females in IVMTE group, aged (68.6±7.5) years (range: 54 to 87 years). There were 159 males and 63 females in MIME group, aged (66.8±8.8) years (range: 42 to 93 years). A 1∶1 match was performed on both groups by propensity score matching, with 38 cases in each group. The intraoperative conditions and postoperative complication rates of the two groups were compared by t test, Wilcoxon rank, χ2 test, or Fisher exact probability method. Results: Patients in IVMTE group had less intraoperative bleeding ((96.0±39.2) ml vs. (123.8±49.3) ml, t=-2.627, P=0.011), shorter operation time ((239.1±47.3) minutes vs. (264.2±57.2) minutes, t=-2.086, P=0.040), and less drainage 3 days after surgery (85(89) ml vs. 675(573) ml, Z=-7.575, P<0.01) compared with that of MIME group. There were no statistically significant differences between the two groups in terms of drainage tube-belt time, postoperative hospital stay, and lymph node dissection stations and numbers (all P>0.05). The incidence of Clavien-Dindo grade 1 to 2 pulmonary infection (7.9%(3/38) vs. 31.6%(12/38), χ²=6.728, P=0.009), total complications (21.1%(8/38) vs. 47.4%(18/38), χ²=5.846, P=0.016) and total lung complications (13.2%(5/38) vs. 42.1%(16/38), χ²=7.962, P=0.005) in the IVMTE group were significantly lower. Conclusion: Inflatable video-assisted mediastinoscopic transhiatal esophagectomy combined with laparoscopic esophagectomy is safe and feasible, which can reach the same range of oncology as thoracoscopic surgery.

Abstract
Objectives: To investigate the feasibility of using a porcine fibrin sealant to wrap and remove kidney calculi fragments through an isolated porcine kidney model. Methods: In the isolated porcine kidney stone model (implanted with 100 mg, air dried, ≤1 mm human stone fragments, n=6;implanted with 100 mg, air dried, ≤3 mm human stone fragments, n=6), the ureteral soft mirror combined with the 12/14Fr UAS was used to test the effect of stone extraction using only two stone extraction methods: basket extraction (control group, ≤1 mm stone fragments, n=3; ≤3 mm stone fragments, n=3) and basket-sealant extraction (test group, ≤1 mm stone fragments, n=3; ≤3 mm stone fragments, n=3). Compare the stone removal rate and operation time of the two stone retrieval methods. The sealant was put into urine of normal human and observed. Results: Porcine Fibrin Sealant can form a gel in saline and urine and adhere and wrap stone fragments. The time of procedures of test (basket-sealant) and control (basket) group in kidneys implanted with ≤ 1 mm stone fragments were (14.0±4.2) and (29.0±0.7)min (P<0.05) stone clearance rates were (90.9±1.4)% and (48.4±15.7)% (P<0.05), respectively. In kidneys implanted with ≤ 3 mm fragments, time of procedures were (12.8±4.0) and (30.0±0)min (P<0.05) Stone clearance rates were (91.1±5.0)% and (20.7±8.0)% (P<0.05). The Sealant dissolves by itself in normal human urine and normal saline at 37 ℃ for 24 hours. Conclusion: The appropriate concentration of Porcine Fibrin Sealant assisted stone retrieval may become a new method for removing small stone fragments in retrograde intrarenal surgery.

Abstract
Ion cyclotron resonance heating (ICRH), one of the main auxiliary methods, for high-power and long-pulse plasma heating had been developed in Experimental Advanced Superconducting Tokamak (EAST). An impedance matching system, one important part of ICRH, had been developed for high-power injection and transmitter protection by reducing the reflected power from the antenna. The input impedance in the outlet of the stub tuner can be measured by voltage-current probes installed on the coaxial transmission line between the antenna and triple liquid stub tuners, and the optimum liquid levels in the stub tuners can be calculated based on the input impedance. The calculation and adjustment process of the optimum liquid levels are described comprehensively in this article. Finally, impedance matching had been achieved between two shots during EAST experiments. In the near future, a real-time impedance matching system will be developed to prevent large variations of the ICRH antenna impedance and achieve steady-state and long-pulse operation with the ICRH system.

Abstract
Background The aim of this study was to identify novel genetic features of Hunner’s lesion interstitial cystitis (HIC) via comprehensive analysis of the Gene Expression Omnibus (GEO) database. Methods The GSE11783 and GSE28242 datasets were downloaded from GEO for further analysis. Differentially expressed genes (DEGs) were identified and analyzed for functional annotation. The diagnostic markers for HIC were screened and validated using the least absolute shrinkage and selection operator (LASSO) logistic regression and support vector machine recursive feature elimination (SVM-RFE) algorithms. Finally, the cell-type identification by estimating relative subsets of RNA transcripts (CIBERSORT) algorithm was adopted to investigate the correlation between immune cell infiltration and diagnostic markers in HIC. Results A total of 7837 DEGs were identified in GSE11783 and 1583 DEGs in GSE28242. Venn diagrams were used to obtain 16 overlapping upregulated and 67 overlapping downregulated DEGs separately. The LASSO logistic model and SVM-RFE algorithm were used to identify 6 genes including KRT20, SLFN11, CD86, ITGA4, PLAC8, and BTN3A3 from DEGs as diagnostic markers for HIC. Their diagnostic potential in HIC and bladder pain syndrome/interstitial cystitis (BPS/IC) were acceptable. PLAC8 exhibited the best diagnostic performance in BPS/IC with an area under the curve of 0.916. The results of immune infiltration involving GSE11783 revealed that the plasma cell ratio (p = 0.017), activated memory CD4+ T cells (p = 0.009), activated dendritic cells (p = 0.01), eosinophils (p = 0.004), and neutrophils (p = 0.03) were significantly higher in HIC than in normal samples, in contrast to resting mast cells (p = 0.022). A positive correlation existed between diagnostic markers and infiltrating immune cells. Conclusion KRT20, SLFN11, CD86, ITGA4, PLAC8, and BTN3A3 represent novel and potent diagnostic markers for HIC. They also exhibit certain diagnostic potential in BPS/IC. Immune cell infiltration might play a key role in the pathogenesis and progression of BPS/IC.

Abstract
Objective: To investigate the relationship between the examined number of lymph nodes at the N1 station and the clinicopathological characteristics and prognosis of patients with pT1-3N0M0 non-small cell lung cancer (NSCLC). Methods: A total of 337 patients with pT1-3N0M0 NSCLC who underwent radical lung cancer surgery at the Provincial Hospital Affiliated to Anhui Medical University from January 2013 to March 2015 were selected. The receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut-off value for predicting 5-year survival in pT1-3N0M0 NSCLC patients by the examined number of lymph nodes at the N1 station. The relationships between the examined number of lymph nodes at the N1 station and the clinicopathological characteristics and prognosis of patients with pT1-3N0M0 NSCLC were analyzed according to the optimal cut-off group. Results: A total of 1 321 lymph nodes at N1 station were examined in 337 patients, with a mean of 3.9 nodes per patient. The median survival time was 42.0 months, with 1-, 3- and 5-year survival rates of 82.2%, 57.1% and 24.9%, respectively. ROC curve analysis showed that the optimal cut-off value of 4.5 lymph nodes examined at the N1 station was used to predict 5-year survival in patients with pT1-3N0M0 NSCLC. After rounding off the number, the number of lymph nodes examined at the N1 station was 5 as the cut-off value, and the patients were divided into the group with <5 lymph nodes examined (212 cases) and the group with ≥5 lymph nodes examined (125 cases). The proportion of patients received adjuvant chemotherapy was 19.2% in the group with ≥5 lymph nodes examined, which was higher than 9.0% in the group with <5 lymph nodes examined (P=0.007), and the differences in other clinicopathological characteristics between the two groups were not statistically significant (P>0.05). The median survival time for patients in the group with <5 lymph nodes examined was 38.0 months, with 1-, 3- and 5-year survival rates of 80.1%, 52.5% and 15.6%, respectively. The median survival time for patients in the group with ≥5 lymph nodes examined was 48.0 months, and the 1-, 3- and 5-year survival rates were 85.6%, 64.0% and 36.0%, respectively. The survival rate of patients in the group with ≥5 lymph nodes examined was better than that in the group with <5 lymph nodes examined (P=0.002). Multifactorial Cox regression analysis showed that T stage (OR=1.408, 95% CI: 1.118-1.670) and the examined number of lymph nodes at N1 station (OR=0.670, 95% CI: 0.526-0.853) were independent influence factors for the prognosis of pT1-3N0M0 NSCLC patients. Conclusion: The examined number of lymph nodes at the N1 station is associated with the prognosis of patients with pT1-3N0M0 NSCLC, and the examination of at least 5 lymph nodes at N1 station at the time of postoperative pathological examination improves the 5-year survival rate of patients.

Abstract
Objective: To compare the efficacy and safety of Tonghua Dongbao's insulin aspart injection (Rishulin) and NovoRapid (Novo Nordisk) in the treatment of diabetes. Methods: A 26-week, randomized, open-label, parallel-group, positive control drug and non-inferiority trial was conducted in 23 centers in China. A total of 563 diabetes with poor blood glucose control treated with insulin for at least 3 months before were included. The subjects were randomized(stratified block random method) into those receiving Rishulin or NovoRapid at a ratio of 3∶1. Both groups were combined with basal insulin (Lantus). The primary endpoint was the change in glycosylated hemoglobin (HbA1c) from baseline to the end of 24 weeks of treatment. Results: For full analysis set, after 24 weeks of treatment, HbA1c level of Ruishulin group decreased from (8.66±1.28)% to (7.77±1.09)% (P<0.001), and that of NovoRapid group decreased from (8.47±1.28) % to (7.65±0.97) % (P<0.001). Treatment difference in HbA1c (NovoRapid group-Ruishulin group) was -0.061% (95%CI -0.320-0.199). HbA1c<7.0% target reacing rates were 24.26% and 21.21% (P=0.456), and HbA1c<6.5% target reacing rates were 9.65% and 6.82% (P=0.310) in Ruishulin group and NovoRapid group, repectively. The standard 2 hours postprandial blood glucose (2hPG) in Ruishulin group decreased from (16.23±5.22) mmol/L to (12.65±4.57) mmol/L (P<0.001), and 2hPG in NovoRapid group decreased from (16.13±5.37) mmol/L to (11.91)±4.21) mmol/L (P<0.001). The fingertips blood glucose at 7-point of both groups exhibited varying degrees of reduction compared with those at baseline, repectively. Positive ratios of specific antibodies were 31.68% in Ruishulin group and 36.36% in NovoRapid group (P=0.320). Ratios of negative to positive were 7.43% and 10.61% (P=0.360), and ratios of positive to negative were 10.40% and 7.58% (P=0.360) in Ruishulin group and NovoRapid group, respectively. The incidence of hypoglycemia was 60.05% and 55.40% (P=0.371), and the incidence of adverse events was 76.60% and 77.70% (P=0.818) in Ruishulin group and NovoRapid group, respectively. Conclusions: Rishulin is not inferior to NovoRapid, and has shown good efficacy and safety. It can be an ideal choice for clinicians in patients with poor blood glucose control with insulin.

Abstract
OBJECTIVE To investigate the distribution and density of Culex mosquito populations and the resistance of Culex pipiens pallens to insecticides in Jiangsu Province in 2018 and 2019. METHODS During the period from June to October in 2018 and 2019, six counties (districts, cities) were sampled in southern, northern and central Jiangsu Province as surveillance sites. The density of Culex mosquitoes was measured overnight using the light trapping technique. In addition, Culex pipiens pallens mosquitoes were collected from Hai'an of Nantong City and Yandu District of Yancheng City, central Jiangsu Province, and the sensitivity of female first filial generations to dichlorodiphenyltrichloroethane (DDT), malation, proposur, beta cypermethrin and deltamethrin was tested using the standard WHO insecticide susceptibility test assay. RESULTS A total of 104 423 Culex mosquitoes were captured in six surveillance sites of Jiangsu Province in 2018 and 2019, and Culex quinquefasciatus (49.11%), Culex pipiens pallens (28.38%), and Culex tritaeniorhynchus (21.04%) were predominant species. The density of Culex mosquitoes started to increase since early June, peaked in July and tended to be low in late October. Culex pipiens pallens mosquitoes captured from Hai'an was susceptible to malation, while those from Yandu District were moderately resistant to malation. Culex pipiens pallens mosquitoes from both Yandu and Hai'an were moderately resistant to proposur, and were resistant to DDT, beta cypermethrin and deltamethrin. CONCLUSIONS Culex quinquefasciatus, Culex pipiens pallens and Culex tritaeniorhynchus are predominant Culex species in Jiangsu Province. Culex pipiens pallens is resistant to DT, beta cypermethrin and deltamethrin in central Jiangsu Province.

OBJECTIVE To analyze the changes of small molecular metabolites in the larvae of a deltamethrin-sensitive strain of Anopheles sinensis following exposure to deltamethrin, so as to provide the scientific basis for investigating the metabolic pathway and screening metabolic markers of deltamethrin in An. sinensis. METHODS The 50% and 75% lethal concentrations (LC50 and LC75) of deltamethrin against the larvae of a deltamethrin-sensitive strain of An. sinensis were calculated in laboratory. The type and content of An. sinensis larvae metabolites were detected using high performance liquid chromatography and mass spectrometry (LC-MS/MS) following exposure to deltamethrin at LC50 and LC75 for 30 min and 24 h, and the changes of metabolites were analyzed. RESULTS The LC50 and LC75 values of deltamethrin were 4.36 × 10-3 µg/mL and 1.12 × 10-2 µg/mL against thelarvae of a deltamethrin-sensitive strain of An. sinensis. Following exposure of the larvae of a deltamethrin-sensitive strain of An. sinensis to deltamethrin at LC50 and LC75 for 30 min, the differential metabolites mainly included organic oxygen compounds, carboxylic acid and its derivatives, fatty acyl and pyrimidine nucleotides, with reduced glucose levels. Following exposure for 24 h, the differential metabolites mainly included organic oxygen compounds, carboxylic acid and its derivatives, aliphatic acyl and purine nucleotides, with increased glucose level detected. CONCLUSIONS Carbohydrate, carboxylic acid and its derivatives, fatty acyls, amino acids and their derivatives may play important roles in deltamethrin metabolism in the larvae of a deltamethrin-sensitive strain of An. sinensis.

Abstract
The long non-coding RNA 00858 (LINC00858) has been reported to be an oncogene for various cancer diseases, including osteosarcoma and colorectal cancer. However, the expression pattern and function of LINC00858 in bladder cancer remain largely unknown. The expression level of LINC00858 was measured in tumor tissues and cell lines by RT-qPCR. The role of LINC00858 in bladder cancer cells were studied by gain- and loss-of-function strategies in vitro. Cell proliferation, migration and invasion were assessed by CCK-8, colony formation, wound healing and Transwell chamber assays. At the molecular level, dual luciferase reporter and RNA RIP assays were performed to identify the interaction among LINC00858, microRNA (miR)-3064-5p and cellular communication network factor 2 (CTGF). The results revealed that the expression level of LINC00858 was upregulated in bladder cancer tissues and cell lines including T24, J82 and 5637. Moreover, knockdown of LINC00858 suppressed cell proliferation, migration and invasion in vitro. Mechanistically, LINC00858 functioned as a competitive RNA to increase the expression level of oncogene CTGF by sequestering miR-3064-5p. In conclusion, LINC00858 knockdown inhibited the proliferation, migration and invasion of bladder cancer cells via regulation of the miR-3064-5p/CTGF axis.

Abstract
Objective: To discuss the complications and postoperative outcomes of tracheotomy with different etiology in children. Methods: One hundred and eighty-six patients underwent tracheotomy were retrospectively analyzed from January 2016 to December 2018,including 117 males and 69 females. The children aged from 4 days to 14 years (median age 31.5months). One case was operated under local anesthesia in emergency room, 2 cases were operated under local anesthesia in pediatric intensive care unit, the rest 183 cases were operated under general anesthesia in operation room. The 186 children were divided into four groups according to their direct causes of tracheotomy. Group A(90 cases): Neuromuscular disease and severe infection,Group B(26 cases): Head and neck tumor,Group C(57 cases): Congenital malformation and upper airway obstruction,Group D(13 cases): Accidental injury. The basic information, surgical complications and postoperative outcomes were recorded and analyzed. All patients were followed up by clinic or by telephone. Spss 19.0 software was used for statistical analysis. Results: One hundred and eighty-six patients were followed up for one to four years. 33 children lost the follow-up and 46 died. Among the 186 patients, 23 cases had emergency tracheotomy (12.4%). The rate of emergency tracheotomy in group C(16 cases, 28.1%) was higher than that in the other three groups(χ2=28.08,P<0.05). The average age of patients and hospital stay in group C were significantly lower than those in the other three groups (F=33.76,P<0.05; F=14.95,P<0.05). Incision bleeding occurred in 11 cases, Subcutaneous emphysema occurred in 6 cases and accidental decannulation occurred in 10 cases (4 cases within 2 weeks and 6 after 2 weeks). Six patients underwent tracheocutaneous fistula closure operation after decannulation and the stoma healed spontaneously in other extubated children. Two patients underwent secondary tracheotomy due to accidental decannulation, and three patients underwent secondary tracheotomy for dyspnea after decannulation. In 107 cases of survival children, decannulation was successful in 65 patients and failed in 42 patients. The average duration of wearing tracheal tube was 8.8 months. The decannulation rates in the four groups were 55.6%, 45%, 69% and 77.8%, with no significant difference. Conclusions: The complications after tracheotomy in children are rare, and no severe complications occurred in long-term tracheotomy patients. The duration of wearing tracheal tube is related to the treatment of their primary disease.

Abstract
BACKGROUND A vascular tumor is a benign tumor with unique clinical and pathological features. Perirenal vascular tumor is extremely rare and has not yet been reported. Clinically, it manifests as soreness and swelling. Color ultrasound and renal angiography illustrated the perirenal mass, which was closely connected with the kidney and the surrounding tissues and organs. Histology showed extensive embedded perirenal fat, and thin-walled vascular tissue displayed a pink stain due to red blood cells.
CASE SUMMARY Herein, a case of robot-assisted retroperitoneal laparoscopic excision of a perirenal vascular tumor is reported. Analysis of the clinical, biological, and histological features of the perirenal vascular tumor can provide an in-depth understanding of the disease, which provides a theoretical and practical basis for better diagnosis and treatment.
CONCLUSION This study contributes to a practical basis for the diagnosis and treatment of perirenal hemangiom.

Abstract
Objective: To examine the overall status of the Jiangsu Province Coronary Artery Bypass Grafting Registry database. Methods: The patients date of Jiangsu Province Coronary Artery Bypass Grafting Registry database from October 2017 to December 2019 was collected retrospectively.Risk factors, history, cardiac function (New York Heart Association class), extent of coronary artery lesion, European system for cardiac operative risk evaluation Ⅱ (EuroSCORE Ⅱ), cardiopulmonary bypss, arterial grafts, the numbers and flow of grafts and postoperative major adverse cardiac and cerebrovascular event(MACCE) information were analyzed. The clinical data of patients underwent on-pump CABG(ONCABG) or off-pump CABG (OPCAB) were compared by t test or χ(2) test. Results: Up till December 2019, the database enrolled 7 138 patients, in which 4 661 patients receiving primary isolated CABG. There were 3 486 males and 1 175 females with the age of (64.6±8.1) years (range:31 to 87 years). There were coronary left main disease in 960 patients, triple vessel disease in 3 934 patients, both left main and triple vessel disease in 837 patients, ejection fraction>50% in 3 841 patients, cardiac function class Ⅲ to Ⅳ in 1 664 patients. EuroSCORE Ⅱ was (2.3±0.7)% (range: 0.5% to 35.8%). There were 2 731 patients (58.59%) underwent ONCABG and 1 930 patients (41.41%) underwent OPCAB. There were 4 144 patients (88.91%) for whom the left internal thoracic artery was harvested. Seven centers (2 centers routinely) used left radial artery, 5 centers (3 centers routinely) used the transit time flow meter. The graft was 3.4±0.7 (range:1 to 7), the aortic crossclamp time was (65.0±20.4) minutes (range: 21 to 196 minutes), the cardiopulmonary bypass time was (90.0±24.2) minutes (range: 33 to 227 minutes). In-hospital death ocurred in 84 patients(1.80%), while re-operation in 93 patients (2.00%), myocardial infarction in 71 patients (1.52%), cerebral infarction in 33 patients (0.71%) and dialysis in 56 patients (1.20%). There were 2 936 patients prescribed with secondary prevention drugs(62.99%).Comparing with OPCAB group, ONCABG group had younger age, more female, more diabetes mellitus, more history of myocardial infarction and percutaneous transluminal coronary angioplasty, poorer cardiac function and coronary lesions, higher EuroSCORE Ⅱ, preoperatively (all P<0.05), and was associated with higher MACCE (135/2 731 vs. 71/1 930, χ(2)=4.280, P=0.039), and of more grafts, transfusion and intra-aortic balloon counterpulsation application (all P<0.05). Conclusions: Jiangsu Province Coronary Artery Bypass Grafting Registry database is generally in good operation, and some parameters still need to be improved. Comparing with OPCAB group, ONCABG has more severe preoperative general conditions, while the outcomes is acceptable.

Abstract
Objective: To analyze the improvement of clinical symptoms and recovery of neurological function in adult Japanese encephalitis, and study the prognostic factors. Methods: Follow-up was conducted for 112 hospitalized patients with Japanese encephalitis (JE) in adults at the Department of Neurology of three hospitals in Gansu province from July to October 2016, from July to October 2017, 6 months and 1 year after onset, respectively. The neurological functional recovery was evaluated by modified Ranking Scale (mRS).The influencing factors were analyzed by logistic regression model. Results: Among the 112 adult patients with JE after 1year follow-up, 57% (64/112) were completely recovered (mRS score=0), and 14%(16/112) had mild neurological dysfunction (mRS score=1 or 2 points), 20% (22/112) had moderate to severe neurological dysfunction (mRS score 3 to 5), and 9% (10/112) died. In 102 survivors, decreased consciousness were fully recovered (100%), 75% of the mental and behavior disorders, 64% of cognitive/memory impairment, 71% of language function disorder, 61% of paralysis, 73% of extrapyramidal symptoms were fully recovered, and 92% of the seizures were controlled. Comparison of clinical data of initial on-set between good prognosis group (mRS score≤2, 80 cases) and poor prognosis group (mRS score>2, 32 cases) showed that initial clinical manifestation with seizures, consciousness (GCS score), cerebrospinal fluid pressure, and lesion of MRI involved in midbrain had statistically significant differences (all P<0.05) . Multivariate analysis demonstrated that cerebrospinal fluid (CSF) pressure>250 mmH(2)O and lesion of midbrain in MRI were independent risk factors of poor prognosis in adult patients with JE. Conclusion: JE is an acute and infectious viral encephalitis of the central nervous system with high disability and mortality. Most patients were completely recovered, and some had neurological sequelae. CSF pressure>250 mmH(2)O and lesion of midbrain in MRI are independent risk factors for poor prognosis.

Abstract
Objective:To discuss the diagnosis and evaluation of upper airway obstruction in neonates, classify the possible causes of neonatal upper airway obstruction, establish a standardized diagnosis and treatment procedure to improve the of treatment efficacy. Method:Clinical data of 71 cases with upper airway obstruction history were retrospective analyzed, 38 cases were treated by combined medical and surgical treatment, 17 cases underwent medical treatment, 16 cases abandonment the treatment. The effectiveness of fibrolaryngoscope, CT, neck ultrasound, MRI and other results was evaluated, and to analyze the prognosis of the treatment, the outcomes and risk factors were also analysed, to evaluate risk factors associated with upper airway obstruction. Result:Fifty-five cases were cured or improved. The mortality rate of 16 children who gave up treatment and left hospital automatically was 81.25%(13/16). The accuracy rate of flexible laryngoscope in detecting the level of upper airway obstruction was 100%, the coincidence rate of B-ultrasound for upper airway cystic occupation was 100%. Etiological order from high to low was congenital space-occupying lesions, congenital upper airway malformation, vocal cord paralysis, Pierre-Robin syndrome. The site of obstruction has a significant influence on the severity of upper airway obstruction(P<0.05). The cure rate of the non-endotracheal intubation group was higher than that of the endotracheal intubation group(P<0.05). Conclusion:The obstruction site of upper airway significantly affects the outcome and the severity of the disease. Upper airway space occupying lesions are the primary causes of upper airway obstruction in neonates. Early assessment and timely treatment can improve the cure rate and improve the prognosis. Internal medicine combined with surgical treatment is effective in relieving upper airway obstruction.

Abstract
Objective: To investigate the snoring status and related family factors of children from 3 to 14 years old in Beijing. Methods: From May to July, 2015, data of children from 3 to 14 years old were obtained from a status survey from 7 districts(Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou) in Beijing. A total of 11 420 children from 25 primary and middle schools were randomly selected. Pediatric Sleep Questionnaire (PSQ) and a self-administered questionnaire were carried out for the adopted children. Self-administered questionnaire included the snoring related family factors. Logistic regression was used to estimate the odd ratio(OR) with 95% confidence intervals for variables. Results: A total of 9 198 children meet the inclusion criteria and are analyzed in the study, of whom 901 (9.80%) were found with snoring behavior. The incidence of boys is higher than girls. Obese children take higher risk of snoring. Compared with younger children (≤6 years old), older children (≥12 years old) have a significantly lower risk of snoring (OR=0.464, 95%CI 0.368-0.585). There is no statistical association between full-term infants, infant feeding pattern, parental cigarette smoking and child snoring.The children with family history of snoring have a significantly higher risk of snoring occurrence. The educational background of mother is statistically related to children snoring (OR=1.241, 95%CI 1.058-1.457). Conclusions: The incidence of children snoring in Beijing is 9.80%, male gender, obesity, and young age are all risk factors for children snoring. There is a significantly statistical relationship between snoring and related family factors, such as family snoring history and education experience.

Abstract
Objective: To investigate the sleep quality of children in Beijing and to analyze the related factors. Methods: The data were collected from the survey of 3-14 years old children in 7 urban districts of Beijing in 2015. By using multi-stage stratified cluster random sampling method, 26 kindergartens and primary and secondary schools in 7 districts and counties, including Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou, were randomly selected, with a total of 11 420 children. Children's sleep status was investigated with Children's Sleep Questionnaire (PSQ), and the proportion of children with sleep quality problems when the PSQ score was greater than 7. Various sleep related factors were investigated with self-made questionnaire. A multilevel model was used to analyze the relationship between PSQ score and related factors. Results: The average PSQ score of the children was 3.60±2.69. The proportion of children with sleep quality problems was 8.87%(816/9 198). Multilevel model analysis showed that the younger the children, the higher the PSQ score (<6 years old vs. 6~12 years old vs. >12 years old: 3.94±2.58 vs. 3.58±2.66 vs. 3.30±2.84, F=33.015, P<0.001); male PSQ score higher than female (3.89±2.75 vs. 3.30±2.60, t=10.560, P<0.001); and snoring, obesity, father/mother snoring, playing games before bed, surfing the internet, eating and other factors were statistically related to PSQ. Conclusions: Sleep quality of children in Beijing should not be neglected, especially preschool children with high PSQ scores. Parents should pay attention to children's snoring problems and try to reduce some pre-sleep behaviors that may affect sleep quality.

Abstract
Objective The amplitude of low-frequency fluctuation (ALFF) fMRI technique was used to study the changes of spontaneous brain activity in patients with diabetic retinopathy and nephropathy (DRN), and to explore the application of ALFF technique in the potential prediction and the targeted prevention of diabetic microangiopathy. Methods Nineteen patients with diabetic retinopathy and nephropathy and 19 healthy controls (HCs) were matched for age and gender. Spontaneous cerebral activity variations were investigated using the ALFF technique. The average ALFF values of the DRN patients and the HCs were classified utilizing receiver operating characteristic (ROC) curves. Results In contrast to the results in the HCs, the patients with DRN had significantly higher ALFF values in the cerebellum (bilaterally in the posterior and anterior lobes) and the left inferior temporal gyrus, but the ALFF values of the bilateral medial frontal gyrus, right superior temporal gyrus, right middle frontal gyrus, left middle/inferior frontal gyrus, bilateral precuneus, and left inferior parietal lobule were lower. ROC curve analysis of each brain region showed the accuracy of AUC was excellent. However, the mean ALFF values in the different regions did not correlate with clinical performance. The subjects showed abnormal neuronal synchronization in many areas of the brain, which is consistent with cognitive and visual functional deficits. Conclusion Abnormal spontaneous activity was detected in many areas of the brain, which may provide useful information for understanding the pathology of DRN. Abnormal ALFF values of these brain regions may be of predictive value in the development of early DRN and be a targeted intervention indicator for individualized treatment of diabetic microvascular diseases.

Abstract
Objective: To investigate the sleep structure and related factors in children with severe obstructive sleep apnea-hypopnea syndrome(OSAHS). Method: We summarized the characteristics of 250 children withsevere OSAHS diagnosed by polysomnography(PSG)in our hospital from January 1, 2017 to December 31, 2017. According to AHI, the patients were divided into three groups, 159 in group A with 20 < AHI≤0, 57 in group B with 40 < AHI≤60, and 34 in group C with AHI > 60. We collected the basic data, sleep parameters (sleep efficiency, latency, sleep stage, sleep index, etc.), preoperative arterial blood gas test results (awake and postsleep state), echocardiographic findings of the three groups. Statistical comparisons between groups were performed with SPSS19.0. Result: BMI, AHI, OAHI, LSaO₂ was significantly different with among the three groups (all P<0.01), and there was a linear correlation between BMI and AHI (r=0.251). There was significant differences in sleep efficiency (SE), sleep latency (SO), and rapid eye movement (REM) latency among the three groups. Compared with group A, the proportion of sleep in stage 1 increased by 38%, the proportion of sleep in stage 3+4 was decreased by 19%, and the proportion of REM was decreased by 14% in group C. There was no significant difference between group A and B. There was a significant linear correlation between AHI and ODI in NREM and REM, respectively (r¹=0.663, r₂=0.499, P< 0.001), and the ODI in REM (63.8±35.0) was significantly higher than that in NREM (29.7±36.0), accounting for 68% of the sleep. Sixty-five children had received preoperative arterial blood gas test (awake and post-sleep state). There was a significant negative correlation between AHI and SaO₂ after sleep (r=-0.444, P=0.000), and no significant correlation in awake state. Forty-four patients underwent preoperative echocardiographic examination. There was significant differences between group A and C in interventricular septum thickness, left ventricular diameter, and main pulmonary artery diameter (P<0.05). There was no significant difference between group A and B. There were no significant differences in aortic annulus diameter, left atrial diameter, left ventricular end diastolic dimension (LVEDD), ejection fraction(EF), and right ventricular anteroposterior diameter among the groups (P>0.05). Conclusion: Obesity is an important factor affecting the severity of OSAHS. As the severity of disease increased, the proportion of awakening time and stage 1 of sleep increased, but stage 3, 4 and REM decreased significantly. The SE, SO, and REM latency were significantly associated with the severity of OSAHS. The severity of hypoxemia is significantly related to AHI, and mainly occur in REM stage. Severe OSAHS is risk factor for cardiovascular complications.

Abstract
The aim of the study was to estimate the value of detecting pepsinogen (PG) I, PGII, and gastrin-17 (G-17) levels in serum for chronic atrophic gastritis (CAG) screening and to determine the clinical applicability of combined measurement of serum G-17, pepsinogens (PGI, PGII) and PGI/PGII ratio (PGR) as a screening test for CAG. The PGI, PGII, and G-17 levels were detected by ELISA in 68 patients with CAG and 86 healthy volunteers who underwent gastroscopy for gastroduodenal diseases at Taizhou Municipal Hospital between January 2016 and December 2016. Concentrations of all measured serum markers were lower in patients with CAG in comparison to healthy volunteers and achieved statistical significance (P<0.01) in PGI (93.25 vs 126.98) and PGR (12.67 vs 17.09). Receiver operating characteristic (ROC) curve analysis revealed the optimal cut-off values for PGI, PGII, PGR, and G-17 at 98.10 μg/l, 6.92 ng/l, 15.77 and 1.94 pmol/l, with sensitivities of 72.10%, 58.10%, 61.60%, and 59.30% and specificities of 61.8%, 51.50%, 77.90%, and 55.90%, respectively. The areas under the curve (AUCs) of PGI, PGR, and G-17 were 0.728, 0.726, and 0.556, respectively. The increase of AUC was observed only in PGR and G-17 combination (0.741) with increased sensitivity (69.10% vs 61.60%) of screening for CAG, whereas the specificity was reduced (72.10% vs 77.90%) in comparison to PGR alone. Combination of serum indicators can raise the diagnosis accuracy of CAG in some respects. However, further research including a larger sample size is necessary in order to accurately determine the sensitivity and specificity of combined detection of serum indicators.

Abstract
As the most commonly occurring form of primary renal tumor, renal cell carcinoma (RCC) is a malignancy accompanied by a high mortality rate. 3-phosphoinositide-dependent protein kinase 1 (PDK1) has been established as a protein target and generated considerable interest in both the pharmaceutical and academia industry. The aim of the current study was to investigate the effect of si-PDK1 on the RCC cell apoptosis, proliferation, migration, invasion and epithelial mesenchymal transition (EMT) in connection with the PI3K-PDK1-Akt pathway. Microarray analysis from the GEO database was adopted to identify differentially expressed genes (DEGs) related to RCC, after which the positive expression of the PDK1 protein in tissue was determined accordingly. The optimal silencing si-RNA was subsequently selected and RCC cell lines 786-O and A498 were selected and transfected with either a si-PDK1 or activator of the PI3K-PDK1-Akt pathway for grouping purposes. The mRNA and protein expressions of PDK1, the PI3K-PDK1-Akt pathway-, EMT- and apoptosis-related genes were then evaluated. The effect of si-PDK1 on cell proliferation, apoptosis, invasion and migration was then analyzed. Through microarray analysis of GSE6344, GSE53757, GSE14762 and GSE781, PDK1 was examined. PDK1 was determined to be highly expressed in RCC tissues. Si-PDK1 exhibited marked reductions in relation to the mRNA and protein expression of PDK1, PI3K, AKT as well as Vimentin while elevated mRNA and protein expressions of E-cadherin were detected, which ultimately suggested that cell migration, proliferation and invasion had been inhibited coupled with enhanced levels of cell apoptosis. While a notable observation was made highlighting that the PI3K-PDK1-Akt pathway antagonized the effect of PDK1 silencing. Taken together, the key observations of this study provide evidence suggesting that high expressions of PDK1 are found in RCC, while highlighting that silencing PDK1 could inhibit RCC cell proliferation, migration, invasion and EMT by repressing the PI3K-PDK1-Akt pathway.

Abstract
Sporadic Creutzfeldt-Jakob disease (sCJD), the most common human prion disease, is transmissible through iatrogenic routes due to abundant infectious prions [misfolded forms of the prion protein (PrPSc)] in the central nervous system (CNS). Some epidemiological studies have associated sCJD risk with non-CNS surgeries. We explored the potential prion seeding activity and infectivity of skin from sCJD patients. Autopsy or biopsy skin samples from 38 patients [21 sCJD, 2 variant CJD (vCJD), and 15 non-CJD] were analyzed by Western blotting and real-time quaking-induced conversion (RT-QuIC) for PrPSc Skin samples from two patients were further examined for prion infectivity by bioassay using two lines of humanized transgenic mice. Western blotting revealed dermal PrPSc in one of five deceased sCJD patients and one of two vCJD patients. However, the more sensitive RT-QuIC assay detected prion seeding activity in skin from all 23 CJD decedents but not in skin from any non-CJD control individuals (with other neurological conditions or other diseases) during blinded testing. Although sCJD patient skin contained ~103- to 105-fold lower prion seeding activity than did sCJD patient brain tissue, all 12 mice from two transgenic mouse lines inoculated with sCJD skin homogenates from two sCJD patients succumbed to prion disease within 564 days after inoculation. Our study demonstrates that the skin of sCJD patients contains both prion seeding activity and infectivity, which raises concerns about the potential for iatrogenic sCJD transmission via skin.

Abstract
Objective: To investigate the snoring status of school-aged children in Beijing and explore the association of snoring and academic performance. Methods: A total of 7 925 children aged from 6 to 14 were selected from 15 primary and middle schools at 7 districts (Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou) in Beijing in 2015, using multi-stage stratified cluster random sampling method. The recruited children were asked to complete the Pediatric Sleep Questionnaire (PSQ) and a questionnaire related to sleep behavior. The multiplelogistic regression was used to analyze the association of snoring and academic performance. Results: A total of 794 (12.44%) children showed a decline in academic performance among 6 383 eligible respondentsfor data analysis. 580 (9.08%) children with snoring was identified, of which 333 and 247 were in frequency of 1-2 times per week and frequency of ≥3 times per week, respectively; 357, 170 and 53 were in snoring grade Ⅰ, grade Ⅱ and grade Ⅲ, respectively. Compared with the children without snoring, the OR (95%CI) for children with 1-2 times per week and ≥3 times per week was 1.363 (1.000-1.857) and 1.605 (1.135-2.269), respectively; and the OR (95%CI) for children with grade Ⅰ, grade Ⅱ and grade Ⅲ of snoring was 1.226 (0.893-1.683), 1.595 (1.062-2.397) and 2.31 (1.17-4.565), respectively. Conclusion: There is a statistical relationship between snoring and the decline of academic performance. The decline of academic performance positively associated with increased frequency and grade of snoring.

Abstract
Objective: To analyze the learning curve of uniportal video-assisted thoracoscopic surgery (VATS) lobectomy for the treatment of resectable lung cancer. Methods: The clinical data of 160 patients with resectable lung cancer who underwent uniportal VATS lobectomy by a single surgical team between May 2016 and April 2017 at Department of Thoracic Surgery, the First Affiliated Hospital of the University of Science and Technology of China were analyzed retrospectively. The study group consisted of 90 male and 70 female patients with age of 28 to 84 years (median: 62 years). The patients were divided into four groups from group A to D according to chronological order. The operation time, incision length, intraoperative blood loss, number of dissected lymph nodes and nodal stations, the proportion of changes in operation mode, postoperative complications, chest drainage duration and hospitalization time were individually compared among the four groups by variance analysis and χ(2) test. Results: The 4 groups were similar in terms of incision length, chest drainage duration, number of dissected lymph nodes and nodal stations and postoperative hospitalization time (P>0.05). The difference of the operation time ((185.9±17.9) minutes vs. (139.9±10.7) minutes vs.(128.7±7.8) minutes vs.(124.0±9.3) minutes, F=219.605, P=0.000), intraoperative blood loss ((233.9±135.8) ml vs. (126.8±18.1) ml vs. (116.4±22.6) ml vs.(112.8±25.3) ml, F=26.942, P=0.000), the proportion of changes in operation mode (17.5% vs.7.5% vs. 5.0% vs. 5.0%, χ(2)=8.300, P=0.040), and the incidence of postoperative complications (27.5% vs. 10.0% vs. 10.0% vs. 7.5%, χ(2)=8.643, P=0.034) among the 4 groups was statistically significant. Conclusions: Uniportal VATS lobectomy can be safely and feasibly performed for resectable lung cancer, learning curve for uniportal VATS lobectomy is approximately 40 cases. Operation time, intraoperative blood loss, postoperative complications and the proportion of changes in operation mode can be used as the main measures during surgery.

Abstract
Diabetes has been recognized as a major risk factor to cause macrovascular diseases and plays a key role in aortic wall remodeling. However, the effects of diabetes on elastic properties of aortas remain largely unknown and quantitative mechanical data are lacking. Thirty adult rabbits (1.6-2.2 kg) were collected and the type 1 diabetic rabbit model was induced by injection of alloxan. A total of 15 control and 15 diabetic rabbit (abdominal) aortas were harvested. Uniaxial and biaxial tensile tests were performed to measure ultimate tensile strength and to characterize biaxial mechanical behaviors of the aortas. A material model was fitted to the biaxial experimental data to obtain constitutive parameters. Histological and mass fraction analyses were performed to investigate the underlying microstructure and dry weight percentages of elastin and collagen in the control and the diabetic aortas. No statistically significant difference was found in ultimate tensile strength between the control and the diabetic aortas. Regarding biaxial mechanical responses, the diabetic aortas exhibited significantly lower extensibility and significantly higher tissue stiffness than the control aortas. Notably, tissue stiffening occurred in both circumferential and axial directions for the diabetic aortas; however, mechanical anisotropy does not change significantly. The material model was able to fit biaxial experimental data very well. Histology showed that a number of isolated foam cells were embedded in the diabetic aortas and hyperplasia of collagen was identified. The dry weight percentages of collagen within the diabetic aortas increased significantly as compared to the control aortas, whereas no significant change was found for that of elastin. Our data suggest that the diabetes impairs elastic properties and alters microstructure of the aortas and consequently, these changes may further contribute to complex aortic wall remodeling.

Abstract
Laryngotracheal stenosis includes congenital laryngotracheal stenosis and secondary laryngotracheal stenosis. Congenital laryngotracheal anomalies are rare, accounting for 0.3%-1.0% of all laryngotracheal stenosis(LTS). Despite the management of pediatric LTS over the past 30 years had been considerable improved, primary surgery still failed in a significant number of complex LTS cases. In some severe LTS cases combined with glottic stenosis, the primary surgery failed around 30%, even with the latest available techniques. Children with LTS usually need multiple operations, and need the tracheostomy tube for months or even years. Therefore, the etiology, clinical features, diagnosis and treatment of laryngotracheal stenosis are summarized in this paper.

Abstract
The present study aims to compare the operative outcomes following the use of robot-assisted retroperitoneal partial nephrectomy (RARPN) with radius, exophytic/endophytic, nearness to sinus, anterior/posterior, and location (RENAL) scoring or laparoscopic retroperitoneal partial nephrectomy (LRPN) for the treatment of renal tumors. Eighty-three nephron-sparing surgery (NSS) procedures performed between January 2013 and December 2015 were reviewed. The study set consisted of 26 robot-assisted retroperitoneal laparoscopes, of which 3 were high risk (RENAL score ≥10), 11 were medium risk (RENAL score ≥7 < 9), and 12 were low risk (RENAL score <7) and 57 laparoscopic retroperitoneal partial nephrectomy procedures (7 high, 22 medium, and 28 low risk). All surgeries were successful in the absence of conversion or transfusion. Operative times were 96.0 ± 16.9 and 110.0 ± 19.4 min for RARPN and LRPN, respectively (P < 0.05). Warm ischemia times (WITs) were 17.6 ± 3.1 and 22.8 ± 3.5 min, respectively (P < 0.05). Estimated blood losses (EBLs) were 45 ± 15 and 97 ± 25 mL, respectively (P < 0.05). No statistical significance was found in duration of drainage, intestinal recovery time, hospital stay, serum creatinine, and perioperative complications (P > 0.05). RARPN affords significant advantages in outcomes of WIT, EBL, and recovery time over conventional LRPN owing to an increased accuracy in excision and suturing. Patients bearing high-risk renal tumors (RENAL score ≥10) are suitable candidates for RARPN.

Abstract
The aim of this study was to evaluate the performance of three new high-risk human papillomavirus (HPV) assays for primary cervical cancer screening, by using self-collected samples, and to identify an HPV assay that could overcome the major obstacles faced during large-scale population-based screening. Two hundred and ten women showing abnormal cervical cytology (and referred for a colposcopy) were recruited in this study. Self-collected samples obtained from all women were tested with the Cobas, Seq, and BioPerfectus Multiplex Real Time HPV assays; simultaneously, clinician-collected samples (from the same women) were tested with the gold-standard Cobas HPV assay. The results of all the assays were consistent. The sensitivity, positive predictive value, and negative predictive value for cervical intraepithelial neoplasia 2+ (CIN2+) and CIN3+ were comparable between the self-collected samples tested with the three new assays and the clinician-collected samples tested with the Cobas HPV assay (P > 0.05). The single-genotype HPV load per sample did not differ significantly between the self- and clinician-collected samples (P = 0.195). In conclusion, the results of this study demonstrated the applicability of the three new HPV assays for primary cervical cancer screening based on self-collection.

Abstract
The objective of this study was to identify disrupted pathways in teratozoospermia by systematically tracking dysregulated modules in reweighted protein-protein interaction (PPI) networks. We inferred and reweighted the PPI networks of normal and teratozoospermia groups based on Spearman correlation coefficients. Modules in the PPI networks were explored via a clique-merging algorithm and altered modules were identified based on maximum weight bipartite matching. Furthermore, pathway-enrichment analyses of genes in altered modules were performed by Database for Annotation, Visualization, and Integrated Discovery (DAVID) to illuminate the biological pathways in teratozoospermia. A total of 20,102 genes were screened from the expression profile. We explored 2406 and 2101 modules in normal and disease PPI networks, respectively. Moreover, we obtained 875 altered modules by comparing modules in normal and teratozoospermia PPI networks. At P < 0.01, the genes involved in 2855 interactions with score changes >1 were mainly enriched in 66 pathways and the genes in altered modules were enriched in 71 pathways. The activity genes (missed and added genes in the disrupted modules) were enriched in 41 common pathways. There were 36 mutual enriched pathways under the five different conditions. Moreover, the cell cycle pathway was disrupted in the first 10 pathways of each condition. This study provides a powerful biomarker discovery platform to better understand the progression of teratozoospermia by systematically tracking dysregulated modules. This method uncovered potential diagnostic and therapeutic targets of teratozoospermia. This information might lead to improved monitoring and treatment of teratozoospermia.

Abstract
Recently, abnormal tumor suppressor gene (TSG) methylation has become a hotspot in the research on colorectal cancer (CRC). This study aimed to explore the influence of CHD5 methylation of CRC TSG on its clinical and pathological characteristics. A total of 40 operation samples as well as corresponding tissue specimens were collected from CRC patients treated in the First Affiliated Hospital of Zhengzhou University from January to December in 2014. CHD5 gene methylation in tissue specimens was detected with methylation specific polymerase chain reaction (MSP); moreover, messenger ribose nucleic acid (mRNA) expression of CHD5 in each tissue was tested using reverse transcription-polymerase chain reaction (RT-PCR), and Western blot was applied to detect the expression of CHD5 protein in those tissues and to analyze the correlation between mRNA and protein of cancer tissue CHD5 as well as the relationship between CHD5 methylation and protein expression. Results revealed that the expression rate of CHD5 methylation in 40 normal mucosal tissues, para-carcinoma tissues, adenoma tissues and CRC tissues was 12.5% (5/40), 22.5% (9/40), 47.5% (19/40) and 72.5% (33/40), respectively. The mRNA expression of CHD5 in the above tissues was 0.225±0.276, 0.169±0.231, 0.147±0.159 and 0.013±0.011 and the protein expression of CHD5 was 0.438±0.205, 0.398±0.180, 0.156±0.1 and 0.024±0.311, respectively. Methylation rate of CHD5 was 87% (20/23) in 23 cases of CHD5 protein loss expression and 52.9% (9/17) in 17 cases of CHD5 protein expression. Results of chi-squared test indicated that there was a significant difference in methylation rate (P less than 0.05), that is, the methylation rate of negatively expressed CHD5 protein was obviously higher than positively expressed protein. Thus, it can be concluded that the CHD5 methylation rate rises gradually in the evolution of CRC, which is related to the occurrence and development of CRC. Furthermore, CHD5 mRNA is positively correlated with protein expression and CHD5 gene methylation is associated with protein loss expression. Therefore, TSG CHD5 methylation of rectal cancer has a great effect in influencing its clinical and pathological features.

Abstract
The cellular prion protein (PrPC), a protein most noted for its link to prion diseases, has been found to play a protective role in ischemic brain injury. To investigate the role of PrPC in the kidney, an organ highly prone to ischemia/reperfusion (IR) injury, we examined wild-type (WT) and PrPC knockout (KO) mice that were subjected to 30-min of renal ischemia followed by 1, 2, or 3 days of reperfusion. Renal dysfunction and structural damage was more severe in KO than in WT mice. While PrP was undetectable in KO kidneys, Western blotting revealed an increase in PrP in IR-injured WT kidneys compared to sham-treated kidneys. Compared to WT, KO kidneys exhibited increases in oxidative stress markers heme oxygenase-1, nitrotyrosine, and Nε-(carboxymethyl)lysine, and decreases in mitochondrial complexes I and III. Notably, phosphorylated extracellular signal-regulated kinase (pERK) staining was predominantly observed in tubular cells from KO mice following 2 days of reperfusion, a time at which significant differences in renal dysfunction, histological changes, oxidative stress, and mitochondrial complexes between WT and KO mice were observed. Our study provides the first evidence that PrPC may play a protective role in renal IR injury, likely through its effects on mitochondria and ERK signaling pathways.

Abstract
AIM To examine the association between depression and impaired glucose regulation, newly diagnosed diabetes and previously diagnosed diabetes in middle-aged and elderly Chinese people, and whether depression was associated with different treatment regimens or durations of diabetes. METHODS A cross-sectional study was performed among 229,047 adults living in the community aged ≥ 40 years from 25 centres in China. The self-reported depression rating scale Patient Health Questionnaire 9 (PHQ-9) was used to diagnose probable and sub-threshold depression. Glucose metabolism status was determined according to World Health Organization 1999 diagnostic criteria. RESULTS The numbers of participants with normal glucose regulation, impaired glucose regulation, newly diagnosed diabetes and previously diagnosed diabetes were 120,458, 59,512, 24,826 and 24,251, respectively. The prevalence of sub-threshold depression in the total sample of participants was 4.8% (4.8%, 4.8%, 4.4% and 5.6% from normal glucose regulation to previously diagnosed diabetes, respectively), and the prevalence of probable depression was 1.1% (1.1%, 1.0%, 0.9% and 1.8% from normal glucose regulation to previously diagnosed diabetes, respectively). Compared with participants with normal glucose regulation, those with previously diagnosed diabetes had increased odds of probable depression [odds ratio (OR) = 1.61, 95% confidence interval (CI) 1.39-1.87] and sub-threshold depression (OR = 1.14, 95% CI 1.06-1.24), after adjustment for multiple confounding factors. Newly diagnosed diabetes or impaired glucose regulation was not associated with depression. Among those with previously diagnosed diabetes, insulin treatment was associated with greater odds of depression compared with no treatment or oral anti-diabetic medicine. CONCLUSION Previously diagnosed diabetes, but not newly diagnosed diabetes or impaired glucose regulation, was associated with a higher prevalence of depression. Patients receiving insulin were more likely to have depression than those not receiving treatment or being treated with oral anti-diabetic medicine.

Abstract
Dendritic cell (DC)-based vaccines are a promising therapeutic modality for cancer. Results from recent trials and approval of the first DC vaccine by the U.S. Food and Drugs Administration for prostate cancer have paved the way for DC-based vaccines. A total of 21 hormone refractory prostate cancer (HRPC) patients with a life expectancy >3 months were randomised into two groups. DC loaded with recombinant Prostate Specific Membrane Antigen (rPSMA) and recombinant Survivin (rSurvivin) peptides was administered as an subcutaneous (s.c.) injection (5×10(6) cells). Docetaxel (75 mg/m(2) intravenous (i.v.)) and prednisone (5 mg, bis in die (b.i.d.)) served as control. Clinical and immunological responses were evaluated. Primary endpoints were safety and feasibility; secondary endpoint was overall survival. Responses were evaluated on day 15, day 30, day 60, and day 90. DC vaccination was well tolerated with no signs of grade 2 toxicity. DC vaccination induced delayed-type hypersensitivity reactivity and an immune response in all patients. Objective Response Rate (ORR) by Response Evaluation Criteria in Solid Tumours (RECIST) was 72.7% (8/11) versus 45.4 (5/11) in the docetaxel arm and immune related response criteria (irRC) was 54.5% (6/11) compared with 27.2% (3/11) in the control arm. The DC arm showed stable disease (SD) in 6 patients, progressive disease (PD) in 3 patients, and partial remission (PR) in two patients compared to SD in 5 patients, PD in 6 patients, and PR in none in the docetaxel arm. There was a cellular response, disease stabilization, no adverse events, and partial remission with the rPSMA and rSurvivin primed DC vaccine.

Abstract
In transmission studies with Alzheimer's disease (AD) animal models, the formation of Aβ plaques is proposed to be initiated by seeding the inoculated amyloid β (Aβ) peptides in the brain. Like the misfolded scrapie prion protein (PrPSc) in prion diseases, Aβ in AD shows a certain degree of resistance to protease digestion while the biochemical basis for protease resistance of Aβ remains poorly understood. Using in vitro assays, histoblotting, and electron microscopy, we characterize the biochemical and morphological features of synthetic Aβ peptides and Aβ isolated from AD brain tissues. Consistent with previous observations, monomeric and oligomeric Aβ species extracted from AD brains are insoluble in detergent buffers and resistant to digestions with proteinase K (PK). Histoblotting of AD brain tissue sections exhibits an increased Aβ immunoreactivity after digestion with PK. In contrast, synthetic Aβ40 and Aβ42 are soluble in detergent buffers and fully digested by PK. Electron microscopy of Aβ40 and Aβ42 synthetic peptides shows that both species of Aβ form mature fibrils. Those generated from Aβ40 are longer but less numerous than those made of Aβ42. When spiked into human brain homogenates, both Aβ40 and Aβ42 acquire insolubility in detergent and resistance to PK. Our study favors the hypothesis that the human brain may contain cofactor(s) that confers the synthetic Aβ peptides PrPSc-like physicochemical properties.

Abstract
Tuberous sclerosis complex (TSC) is an autosomal dominant neurogenetic disorder caused by mutations in the TSC1 or TSC2 genes and is frequently associated with hamartoma formation in multiple organ systems. Here, we report two novel mutations in the TSC2 gene, including a splicing mutation (IVS 29 +1G>C) in intron 29 and a deletion/insertion mutation (C.5090-5092delCCA- inAG) in exon 39 in two Chinese Han children with TSC whose first clinical manifestation was seizure. The identification of these two mutations confirmed the diagnosis of TSC and expands the spectrum of TSC2 mutations causing TSC.

Abstract
We propose a compact nanotube-mode-locked all-fiber laser that can simultaneously generate picosecond and femtosecond solitons at different wavelengths. The pulse durations of picosecond and femtosecond solitons are measured to be ∼10.6 ps and ∼466 fs, respectively. Numerical results agree well with the experimental observations and clearly reveal that the dynamic evolutions of the picosecond and femtosecond solitons are qualitatively distinct in the intracavity. Our study presents a simple, stable, low-cost, and dual-scale ultrafast-pulsed laser source suitable for practical applications in optical communications.

Abstract
Differentiating iatrogenic Creutzfeldt-Jakob disease (iCJD) from sporadic CJD (sCJD) would be useful for the identification and prevention of human-to-human prion transmission. Currently, the diagnosis of iCJD depends on identification of a recognized source of contamination to which patients have been exposed, in addition to fulfilling basic requirements for the establishment of diagnosis of CJD. Attempts to identify differences in clinical manifestations, neuropathological changes and pathological prion protein (PrPSc) between iCJD and sCJD have been unsuccessful. In the present study, using a variety of more sophisticated methods including sucrose step gradient sedimentation, conformational stability immunoassay, protein misfolding cyclic amplification (PMCA), fragment-mapping, and transmission study, we show no significant differences in gel profiles, oligomeric state, conformational stability and infectivity of PrPSc between iCJD and sCJD. However, using PMCA, we find that convertibility and amplification efficiency of PrPSc is greater in iCJD than in sCJD in a polymorphism-dependent manner. Moreover, two protease-resistant PrP C-terminal fragments (termed PrP-CTF12/13) were detected in all 9 cases of sCJD but not in 6 of 8 cases of iCJD tested in this study. The use of fragment mapping- and PMCA-based assays thus provides a means to distinguish most cases of iCJD from sCJD.

Abstract
Selective photothermolysis is the basic principle for laser treatment of vascular malformations such as port wine stain birthmarks (PWS). During cutaneous laser surgery, blood inside blood vessels is heated due to selective absorption of laser energy, while the surrounding normal tissue is spared. As a result, the blood and the surrounding tissue experience a local thermodynamic non-equilibrium condition. Traditionally, the PWS laser treatment process was simulated by a discrete-blood-vessel model that simplifies blood vessels into parallel cylinders buried in a multi-layer skin model. In this paper, PWS skin is treated as a porous medium made of tissue matrix and blood in the dermis. A two-temperature model is constructed following the local thermal non-equilibrium theory of porous media. Both transient and steady heat conduction problems are solved in a unit cell for the interfacial heat transfer between blood vessels and the surrounding tissue to close the present two-temperature model. The present two-temperature model is validated by good agreement with those from the discrete-blood-vessel model. The characteristics of the present two-temperature model are further illustrated through a comparison with the previously-used homogenous model, in which a local thermodynamic equilibrium assumption between the blood and the surrounding tissue is employed.

Abstract
Highly ordered mesoporous Co3O4 nanostructures were prepared using SBA-15 silica as hard templates. The mesoporous structures were characterized by X-ray diffraction, high resolution transmission electron microscopy, and N2 adsorption/desorption isotherm analysis. The results demonstrated that the as-prepared mesoporous Co3O4 has an ordered P6mm symmetric mesoporous structure. The optical absorption properties of the mesoporous Co3O4 were investigatted by UV-Vis spectroscopy and the results indicate that the mesoporous Co3O4 materials are semiconducting with direct band gaps of 2, 1.385 and 0.38 eV. The gas-sensing performance of the mesoporous Co3O4 was tested towards a series of typical solvents. They demonstrated a good sensing performance towards these vapour with rapid response and high sensitivity at low operating temperature.

Abstract
Variations in foliar stable carbon isotope signatures (δ(13)C) of different plant functional groups (PFGs) and their relationships with environmental factors in China were investigated in this meta-analysis. There were some significant, but small differences in δ(13)C among PFGs categorised by life form (<1‰). Trees (-26.78‰) and shrubs (-26.89‰) had similar mean δ(13)C that were significantly higher than those of herbs (-27.49‰). Evergreen shrubs (-25.82‰) had significantly higher mean δ(13)C than deciduous shrubs (-26.92‰). Perennial herbs (-26.83‰) had significantly higher mean δ(13) C than annual herbs (-27.10‰). Grasses (-26.46‰) had significantly higher mean δ(13)C than forbs (-26.96‰). For pooled data, δ(13)C was significantly and negatively correlated with mean annual precipitation (MAP) and mean annual temperature (MAT), while it was significantly and positively correlated with latitude and altitude. There was a threshold value of MAP along the gradients, and δ(13)C did not change significantly with higher rainfall. The δ(13) C of PFGs changed with altitude, suggesting that increases in δ(13)C with altitude cannot be generalised. Differences in δ(13)C between PFGs were generally much <1‰ and therefore insignificant. In contrast, MAP and MAT had relatively large effects on δ(13) C (more than 4‰ between extremes). The δ(13)C of some PFGs responded to environmental gradients in the same manner, while their 'rates' of change were significantly different in some cases. This information could help predict potential changes in the distribution of PFGs in response to future climate change.

Abstract
An elemental sulfur and multi-walled carbon nanotube (S-MWNT) composite was synthesized by dissolving sulfur in ammonium sulfides and then precipitating on MWNT. Morphology observation by scanning electron microscopy (SEM) confirmed that S-MWNT product was successfully prepared by incorporating sulfur into MWNT network. Without additional conducting material, the S-MWNT composite cathodes were prepared for electrochemical tests. The properties measured in discharge-charge cycling test showed that the composite had the initial discharge capacity of 1024 mAh g(-1), which is about 61% sulfur utilization. However, in the subsequent cycling, the capacities faded. To determine the reason of rapid capacity drop, S-MWNT composite cathodes were compared in the cycling tests with varying three kinds of electrolytes and the cathode was subjected to physical force by rolling. The changes in the cycle performances proved that the deterioration of S-MWNT composite cathodes was not related to the electrolytes but to physical bonding that may not maintain the conducting path between sulfur and MWNT.

Abstract
OsGSTL2 is one of three tandem-arranged glutathione S-transferase, lambda class genes in chromosome 3 of rice (Oryza sativa L.). It includes 9 introns and 10 exons, and encodes a protein of 244 amino acid residues with a calculated molecular mass of 27.37 kDa. The predicted three-dimensional structure of OsGSTL2 showed a typical glutathione S-transferase fold. Using semi-quantitative RT-PCR analysis, OsGSTL2 transcript was detected in the roots and leaves of seedling stage and tillering stage, and the roots, leaves and panicles of heading stage from rice plants, and the expression level of OsGSTL2 mRNA in rice roots show significant change under chlorsulfuron stress. The OsGSTL2 gene was cloned into pYTV vector and was transformed into yeast strain PEP4. Western blot analysis showed the exogenous OsGSTL2 was expressed in transformed yeast. GST activity of crude extracts of yeast showed the OsGSTL2 transgenic yeast had higher levels of GST activities than control yeasts. These findings suggested that the OsGSTL2 is a glutathione S-transferase and has potential use in detoxification.

Abstract
Prion diseases are a group of incurable transmissible neurodegenerative disorders. The key molecular event in the pathogenesis of prion diseases is the conversion of the cellular prion protein (PrP(C)) into its pathological isoform (PrP(Sc)), accompanied by a conformational transition of α-helix into β-sheet structure involving the structured α-helix 1 domain from residues 144-154 of the protein (PrP144-154). Blocking the accessibility of PrP144-152 with anti-PrP antibody 6H4 was found to prevent PrP conversion and even to cure prion infection in cell models ( Enari et al. 2001 ). Previously, Yuan et al. (2005 ) demonstrated that the reduction and alkylation of PrP induced concealment of the 6H4 epitope. This study examined the ability of mechlorethamine (MCT), an alkylating antitumor drug, to conceal the 6H4 epitope and block PrP conversion in the presence of a reducing reagent. Mechlorethamine treatment significantly decreased in vitro amplification of PrP(Sc) in the highly efficient protein misfolding cyclic amplification system. Our findings suggest that MCT may serve as a potential therapeutic agent for prion diseases.

Abstract
The epitope of the 3F4 antibody most commonly used in human prion disease diagnosis is believed to consist of residues Met-Lys-His-Met (MKHM) corresponding to human PrP-(109-112). This assumption is based mainly on the observation that 3F4 reacts with human and hamster PrP but not with PrP from mouse, sheep, and cervids, in which Met at residue 112 is replaced by Val. Here we report that, by brain histoblotting, 3F4 did not react with PrP of uninfected transgenic mice expressing elk PrP; however, it did show distinct immunoreactivity in transgenic mice infected with chronic wasting disease. Compared with human PrP, the 3F4 reactivity with the recombinant elk PrP was 2 orders of magnitude weaker, as indicated by both Western blotting and surface plasmon resonance. To investigate the molecular basis of these species- and conformer-dependent preferences of 3F4, the epitope was probed by peptide membrane array and antigen competition experiments. Remarkably, the 3F4 antibody did not react with MKHM but reacted strongly with KTNMK (corresponding to human PrP-(106-110)), a sequence that is also present in cervids, sheep, and cattle. 3F4 also reacted with elk PrP peptides containing KTNMKHV. We concluded that the minimal sequence for the 3F4 epitope consists of residues KTNMK, and the species- and conformer-dependent preferences of 3F4 arise largely from the interactions between Met(112) (human PrP) or Val(115) (cervid PrP) and adjacent residues.
