Abstract
Purpose: Urbanization is causing an increasingly negative effect on public health in China. This study was established to examine the associations between socio-economic and environmental exposures and the potential impact of gene-environment interactions and cancer risk of urban population in Chongqing, China. Participants: The cohort was established in Beibei District of Chongqing in southwest China. Between March 2016 and December 2016, we enrolled 57,332 adults who were 40-69 years of age, and collected baseline data on demographic information, socio-economic status, lifestyle, family and personal disease histories through face-to-face interviews using a standardized questionnaire. Regular follow-up including face-to-face interviews will take place every 5 years. Findings to date: Ninety-nine percent (56658/57332) of the participants completed the baseline assessment. The eligible participants had a mean age of 54.8 years, and 51.42% were females. Nearly three-fifths of participants having a normal BMI (18.5 to 23.9 kg/m2) and one-third being overweight (24.0 to 27.9 kg/m2). Among males, 29.58% were smokers and 21.08% were alcohol users. Among females, 1.49% were smokers and 1.66% were alcohol users. Among all participants, 7.03% of males and 9.08% of females reported their family history of cancer. Future plans: The relationships of modifiable risk factors with the cancer risk will be analyzed. Meanwhile, participants will be closely tracked to minimize loss to follow-up. We plan to construct a risk prediction model on cancer and verify the prediction model by genome-wide association studies (GWAS). The successful completion of this cohort study will allow for better targeting of cancer screening to those at highest risk in urban population of China and provide clinicians and policymakers with a practical predication rule.

Abstract
Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound, the examiner and interpreter of the image are critical care medicine physicians. The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes. With the idea of critical care medicine as the soul, it can integrate the above information and clinical information, bedside real-time diagnosis and titration treatment, and evaluate the therapeutic effect so as to improve the outcome. CUS is a traditional technique which is applied as a new application method. The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept, implementation and application of CUS. It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure. At the same time, the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications, and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS. Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group, based on the rich experience of clinical practice in critical care and research, combined with the essence of CUS, to learn the traditional ultrasonic essence, established the clinical application technical specifications of CUS, including in five parts: basic view and relevant indicators to obtain in CUS; basic norms for viscera organ assessment and special assessment; standardized processes and systematic inspection programs; examples of CUS applications; CUS training and the application of qualification certification. The establishment of applied technology standard is helpful for standardized training and clinical correct implementation. It is helpful for clinical evaluation and correct guidance treatment, and is also helpful for quality control and continuous improvement of CUS application.

Abstract
Objective: To investigate the efficacy and safety of Compound Lactobacillus Tablets or Saccharomyces boulardii Sachets combining with bismuth quadruple therapy for Helicobacter pylori(H.pylori) eradication. Methods: A total of 360 H. pylori- infected patients were enrolled and randomly assigned into three groups. Group A received esomeprazole 20 mg bid+ bismuth potassium citrate 220 mg bid+ amoxicillin 1 000 mg bid+ furazolidone 100 mg bid for 10 days. Group B or group C received the same quadruple therapy for 10 days as group A, as well as Compound Lactobacillus Tablets 1 000 mg tid or Saccharomyces boulardii Sachets 500 mg bid for 14 days. Drug-related side effects and adverse reactions were collected during the therapy, and H. pylori eradication results were confirmed by (13)C/(14)C-UBT at least 4 weeks after cessation of therapy. Results: The H. pylori eradication rates in group A, B and C were 81.7%, 84.2% and 85.0% by ITT analysis (P=0.768) and 92.5%, 90.1% and 93.6% by PP analysis (P=0.770), respectively. The overall side effects and adverse reactions rates (P=0.008) and occurrence of diarrhea (P<0.001) were significantly lower in group B than group A. The overall side effect rates (P=0.003) and occurrence of diarrhea (P<0.001), abdominal distension (P=0.004) and constipation(P=0.002) were significantly lower in group C than group A. There was no significant difference in side effects and adverse reactions rates between the two probiotics groups. Conclusions: Both Compound Lactobacillus Tablets and Saccharomyces boulardii Sachets, combining with bismuth quadruple therapy, reduced the overall side effects and adverse reactions rates for H. pylori eradication. Moreover, the former can reduce the incidence of diarrhea, and the latter can reduce the incidence of diarrhea, abdominal distension and constipation.

Abstract
Objective: To study the relationship between the weight change trend of initial treatment patients with pulmonary tuberculosis and the dose change trend of isoniazid, and therefore to analyze the appropriate dose of isoniazid. Methods: Data of initial treatment inpatients with pulmonary tuberculosis from May 1955 to December 2012 were retrospectively analyzed. Elderly patients with pulmonary tuberculosis, patients with drug-resistant tuberculosis, extrapulmonary tuberculosis and those with complications were excluded from the study. The time period was separated as 20th century 1950s to 1960s, 1970s, 1980s, 1990s, 21th century 2000s and 2010s. Samples were selected in each year and month between 1950s to 1960s and 1970s. After 1980s, samples of 1 year were taken from each 5 years. The sex, age and weight for every patient were collected, as well as the dose of isoniazid of every inpatient on a day in therapeutic regimen. Meanwhile, the weight change trend of the patients in different ages and the dose change trend of isoniazid were compared. The total number of cases was 1 398, with 924 males and 474 females, averaging (36.7±14.4) years old. Results: The weight of the patients increased when it was compared between that in 1950s to 1960s, 1970s or 1980s and that in 2000s, with a increasing weight of 3 kg, 3.5 kg and 3 kg respectively. The difference showed statistical significance (P<0.003). The difference was also significant when the weight in 70s was compared with that in 2010s (P=0.002). The therapeutic dose of isoniazid remained invariable regardless of the weight change. At 1990s, 2000s and 2010s, the dose of isoniazid per kilogram of body weight would reduce to 0.005 4 g, 0.005 2 g and 0.0054 g relative to patients' weight increase, and the difference was statistically significant (P<0.001). Conclusions: The weight of pulmonary tuberculosis inpatients increased in recent 60 years. The weight has a close relation with the dose of isoniazid. A fixed dose of isoniazid (0.3 g/d) regardless of the weight change could result in low blood drug concentration . To avoid tolerance of isoniazid and increase the cure rates of pulmonary tuberculosis, the dosage of isoniazid should be increased based on the weight increase of patients.

Abstract
Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR(2)) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR(2) rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR(2). All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR(2) compared with non-KIT D816 group (23.1% vs 57.1%, χ(2)=7.559, P=0.006), and patients with longer CR(1) duration achieved significantly higher CR(2) than those with CR(1) duration less than 12 months (74.1% vs 31.9%, χ(2)=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR(1) duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion: KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.

Abstract
Feed represents two-thirds of the total costs of poultry production, especially in developing countries. Improvement in feed efficiency would reduce the amount of feed required for production (growth or laying), the production cost, and the amount of nitrogenous waste. The most commonly used measures for feed efficiency are feed conversion ratio (FCR) and residual feed intake (RFI). As a more suitable indicator assessing feed efficiency, RFI is defined as the difference between observed and expected feed intake based on maintenance and growth or laying. However, the genetic and biological mechanisms regulating RFI are largely unknown. Identifying molecular mechanisms explaining divergence in RFI in laying ducks would lead to the development of early detection methods for the selection of more efficient breeding poultry. The objective of this study was to identify duodenum genes and pathways through transcriptional profiling in 2 extreme RFI phenotypes (HRFI and LRFI) of the duck population. Phenotypic aspects of feed efficiency showed that RFI was strongly positive with FCR and feed intake (FI). Transcriptomic analysis identified 35 differentially expressed genes between LRFI and HRFI ducks. These genes play an important role in metabolism, digestibility, secretion, and innate immunity including (), (), (), β (), and (). These results improve our knowledge of the biological basis underlying RFI, which would be useful for further investigations of key candidate genes for RFI and for the development of biomarkers.

Abstract
BACKGROUND Traumatic brain injury (TBI) is a common occurrence following gastrointestinal dysfunction. Recently, more and more attentions are being focused on gut microbiota in brain and behavior. Glucagon-like peptide-1 (GLP-1) is considered as a mediator that links the gut-brain axis. The aim of this study was to explore the neuroprotective effects of Clostridium butyricum (Cb) on brain damage in a mouse model of TBI. METHODS Male C57BL/6 mice were subjected to a model of TBI-induced by weight-drop impact head injury and were treated intragastrically with Cb. The cognitive deficits, brain water content, neuronal death, and blood-brain barrier (BBB) permeability were evaluated. The expression of tight junction (TJ) proteins, Bcl-2, Bax, GLP-1 receptor (GLP-1R), and phosphorylation of Akt (p-Akt) in the brain were also measured. Moreover, the intestinal barrier permeability, the expression of TJ protein and GLP-1, and IL-6 level in the intestine were detected. RESULTS Cb treatment significantly improved neurological dysfunction, brain edema, neurodegeneration, and BBB impairment. Meanwhile, Cb treatment also significantly increased the expression of TJ proteins (occludin and zonula occluden-1), p-Akt and Bcl-2, but decreased expression of Bax. Moreover, Cb treatment exhibited more prominent effects on decreasing the levels of plasma d-lactate and colonic IL-6, upregulating expression of Occludin, and protecting intestinal barrier integrity. Furthermore, Cb-treated mice showed increased the secretion of intestinal GLP-1 and upregulated expression of cerebral GLP-1R. CONCLUSIONS Our findings demonstrated the neuroprotective effect of Cb in TBI mice and the involved mechanisms were partially attributed to the elevating GLP-1 secretion through the gut-brain axis.

Abstract
Essentials The best imaging modality for joint blood detection in hemophilia is unknown. Blood appearance and detection thresholds were studied with ultrasound and conventional MRI. Ultrasound is sensitive to low volume and concentration of blood, whereas conventional MRI is not. The findings establish the validity of ultrasound for rapid bleed detection in hemophilia care. SUMMARY Background There is increasing demand for musculoskeletal ultrasound (MSKUS) to detect hemophilic joint bleeding, but there is uncertainty regarding blood detection concentration thresholds or if magnetic resonance imaging (MRI) is more accurate. Aims Compare the sensitivity of blood detection by MSKUS and MRI. Methods Increasing blood concentrations in plasma were imaged with MSKUS and MRI 1-2 h, 3-4 days and 7 days after blood withdrawal in vitro, and after injection into cadaveric pig joints. Additionally, effusions in the joints of two patients with hemophilia joints were imaged, followed by aspiration. MSKUS was performed using an 8-18-MHz linear transducer; MRI was performed at 3T using T1-weighted and T2-weighted fat-suppressed sequences. Images were reviewed by a hematologist certified in MSKUS and a musculoskeletal radiologist. Results MSKUS permitted the detection of blood in vitro and in pig joint spaces at concentrations as low as 5%, demonstrated by the presence of echogenic signals that were absent with plasma alone. In contrast, no differences between fluids were discernible on the T1-weighted or T2-weighted MRI images. Results were confirmed in the two patients with hemophilia. Blood clots demonstrated varying and dynamic echogenicity patterns over time and, using MRI, were visualized best with T2 sequences. Conclusion MSKUS is extremely sensitive in detecting low concentrations of intra-articular blood and in discriminating between bloody and non-bloody fluid, whereas conventional MRI is not. These observations demonstrate the advantages of MSKUS over MRI in detecting intra-articular blood, and show that MSKUS is ideal for rapid bleed detection in the clinic.

Abstract
We demonstrate that a bipolar non-volatile resistive switching behaviour with negative differential resistance (NDR) effect is realized in a Cu/BaTiO3/Ag device, which was deposited on a Si substrate via magnetron sputtering equipment. We suggest that the bipolar resistive switching is dominated by the trapping/detrapping of electrons at the BaTiO3-Cu interface. In addition, we demonstrate that the device exhibits good performance, including a large on/off ratio, high reliability and long retention time. Therefore, BaTiO3 may become a good candidate for application in resistive switching random access memory (RRAM) devices.

Abstract
AIM MICAL2, a cytoskeleton dynamics regulator, is identified associated with survival and metastasis of several types of cancers recently. This study was designed to investigate the role of MICAL2 in breast cancer cell migration as well as its underlying mechanisms. METHODS The relationship between MICAL2 and EGF/EGFR signalling was analysed by gene overexpression and knock-down techniques. Cell migration was measured by wound-healing assays. Activation of EGF/EGFR signalling pathways were evaluated by immunofluorescence, qPCR, Western blotting and zymography techniques. Rac1 activity was assessed by pull-down assay. Correlation of MICAL2 and EGFR in breast cancer specimens was examined by immunohistochemical analysis. RESULTS Ectopic expression of MICAL2 in MCF-7 cells augmented EGFR protein level, accompanied by the promotion of cell migration. Silencing MICAL2 in MDA-MB-231 cells destabilized EGFR and inhibited cell migration. In mechanism, the maintaining effect of MICAL2 on EGFR protein content was due to a delay in EGFR degradation. Expression of MICAL2 was also shown positively correlated with the activation of P38/HSP27 and P38/MMP9 signallings, which are the main downstream signalling cascades of EGF/EGFR involved in cell migration. Further analysis indicated that Rac1 activation contributed to the maintaining effect of MICAL2 on EGFR stability. In addition, analysis of breast cancer specimens revealed a positive correlation between MICAL2 and EGFR levels and an association between MICAL2 expression and worse prognosis. CONCLUSION MICAL2 is a major regulator of breast cancer cell migration, maintaining EGFR stability and subsequent EGFR/P38 signalling activation through inhibiting EGFR degradation in a Rac1-dependent manner.

Abstract
Objective: To evaluate the consistency in detection of T790M mutation of epidermal growth factor receptor gene (EGFR) in plasma and tumor samples of patients with lung adenocarcinoma. Methods: The tumor tissues or cytological specimens of 12 patients with operable lung adenocarcinoma(stage Ⅰ-ⅢA) and 100 patients with advanced stage ⅢB-Ⅳ lung adenocarcinoma were collected, among which 11 patients showed acquired resistance for gefitinib (11/100). In the same period, peripheral blood samples were collected from all patients and 50 healthy volunteers. Amplification refractory mutation system (ARMS) was used to detect EGFR mutations in tumor specimens. Next Generation Sequencing(NGS) based circulating single-molecule amplification and resequencing technology (cSMART)was performed to quantitatively detect the EGFR mutations in circulating tumor DNA (ctDNA) from plasma specimens. Results: The sensitivity, specificity and concordance rate of EGFR T790M mutation between plasma and tissue specimens from 100 advanced stage patients were 50.0%, 72.9% and 72.0%, respectively. For L858R mutation and exon 19 deletion mutations, the above mentioned sensitivity, specificity and concordance rate were 91.7%, 100.0%, and 98.0%, as well as 79.2%, 100.0% and 95.0%, respectively. The L858R mutation and exon 19 deletion mutations were not detected in plasma of 50 healthy volunteers, whereasT790M mutation(1.0±0.0 copies) was found in 7 individuals(7/50, 14.0%). Similarly, in 12 resectable patients, 4 (4/12, 33.3%) T790M mutations were found in plasma (1.2±0.2 copies), but no L858R mutation and 19 exon deletion mutations. In comparison, 28.0% of patients with advanced lung adenocarcinoma (28/100)had detectable T790M mutation in plasma with copy numbers (34.0±22.7 copies). Furthermore, the copy numbers of T790M were 268.2±119.9 in plasma of 5 cases with acquired gefitinib-resistance. Conclusions: In patients with advanced stages of lung adenocarcinoma, the detection of T790M mutation in plasma and tumor specimens is low. The T790M mutation also exists in the plasma of some healthy controls, suggesting that T790M mutation participates in EGFR signaling pathway and it might function in healthy population.

Abstract
Objective: To analyze clinical features, prognosis and treatment of lymphocytic hypophysitis (LYH). Methods: The clinical data, treatments and outcomes of 18 cases diagnosed as LYH at Chinese PLA General Hospital between January 2001 and July 2017 was respectively reviewed. Results: Eighteen patients with histology-proven LYH (13 females and 5 males ) were identified. All lymphocytic adenohypophysitis (LAH) were females(n=6), two of whom were associated with pregnancy. Eleven patients (6 females and 5 males) had lymphocytic panhypophysitis (LPH) and one(female) had hypothalamitis. Pre-treatment evaluation revealed that 11 patients presented with symptoms of intracranial space-occupying lesions, 12 patients had symptoms of anterior pituitary hormone deficiencies, and 12 patients had central diabetes insipidus (CDI). All patients had space-occupying lesions on magnetic resonance imaging (MRI), which were symmetrically enlarged and homogenously enhanced with or without pituitary stalk thickening. Before or after surgery, 11 patients received immunosuppressant therapy or radiotherapy to alleviate space-occupying effect. After 4-204 months follow-up, 5 patients had a relapse and received immunosuppressants, radiotherapy or surgery to achieve remission. Full recovery (both symptomatic and radiographic) was seen in 6 patients, and 11 patients maintained stable replacement therapy. Conclusions: LYH presents with acute space-occupying effects such as headache, visual disturbances, hypopituitarism, CDI and mild hyperprolactinemia, especially with characteristic radiographic manifestations. Usually, surgery reliably establishes diagnosis, and immunosuppressant therapy is a necessity. On the whole, LYH has a good prognosis.

Abstract
Setting: Three projects of the Fund for Innovative DOTS Expansion through Local Initiatives to Stop TB. Objectives: To assess unfavourable treatment outcomes (UTOs), including failure, died, loss to follow-up (LTFU), transferred out and unknown outcome, and to identify risk factors associated with UTOs. Design: This was a cross-sectional study using routine programme data. Results: Of 30 277 new smear-positive tuberculosis (TB) patients, 4261 (14.1%) had UTOs: 2048 (6.8%) LTFU, 1418 (4.7%) transferred out, 390 (1.3%) died, 340 (1.1%) failed and 65 (0.2%) had an unknown outcome. Risk factors for LTFU (including LTFU, transfer out and unknown outcome) were residing in Anhui, age > 55 years, service delay > 10 days, patient delay < 30 days, directly observed treatment (DOT) provided by a family member or others and unknown DOT provider. The outcome of 'died' was associated with residing in Shaanxi, age > 55 years, male sex, patient delay > 30 days and unknown DOT provider. 'Failed' was associated with having unlimited access to health services, patient delay of >30 days and unknown DOT provider. Conclusion: This study highlights the predominance of lost patients among UTOs. Patients with family members or other non-medical DOT providers or unknown DOT providers had a high risk of a UTO. There is an urgent need to address these service-related factors.

Abstract
Objective: To summarize and analyze the clinical features and etiologies in hospitalized patients with syndrome of inappropriate antidiuretics (SIAD) during the past 25 years. Methods: All data of 128 patients with SIAD admitted to Chinese PLA General Hospital since January 1991 to January 2016 were collected. SIAD was diagnosed based on the 1957 criterion. Results: (1) The most frequent causes of increased inappropriate secretion of vasopressin were malignant tumors, lung diseases (e. g. pneumonia), and central nervous system diseases, in which malignant tumors accounted for 38.28% of the SIAD. (2) During the past 25 years, the proportion of malignant diseases declined from 4/7 to 35.29%, while, the proportion of pulmonary infection increased from 1/7 to 35.29% (P<0.05). (3) The patients with malignant tumors had the lowest serum sodium and serum osmolality among all SIAD patients. (4) CT scan had a high diagnostic value for chest and brain detection. (5) Among three SIAD subjects with unknown reasons at onset, two were diagnosed with small cell lung cancer and one with gastric cancer during follow-up. Conclusion: The etiology of SIAD is complex and it could be attributed to multifarious etiological factors. Malignant tumors account for the largest proportion of all patients, and pulmonary infection was ranked in second place. Cautions on tumors have to be taken when serum sodium of a SIAD patient is below 118.1 mmol/L.

Abstract
The closure of gaps within epithelia is an essential part of many physiological and pathological processes, such as embryonic development, organ remodeling and wound healing. Emerging evidence proved that the physical microenvironment plays important roles in cell behaviors. However, the effect of osmolarity of extracellular medium on gap closure is least understood. Using a gap closure model of epithelial cells, we found that hypotonic condition significantly facilitated the process of gap closure. Moreover, instead of actomyosin ring, enhanced migration leading by lamellipodia primarily contributed to the rapid gap closure in hypotonic condition. These findings provide insights for understanding the physiology of epithelial gap closure.

Abstract
Primary ovarian insufficiency (POI) is the depletion or loss of normal ovarian function, which cause infertility in women before the age of 40 years. Two homozygous germline truncation mutations in STAG3 gene had been reported to causes POI in consanguineous families. Here, we aimed to identify the genetic cause of POI in 2 affected sisters manifested with primary amenorrhea and partial development of secondary sexual characters with normal range of height of a consanguineous Han Chinese family. Whole-exome and Sanger sequencing identified a homozygous donor splice-site mutation (NM_012447.2: c.1573+5G>A) in the STAG3 gene. RT-PCR revealed that the mutation causes loss of wild-type donor splice-site which leads to aberrant splicing of STAG3 mRNA and consecutive formation of STAG3 alternative transcript (p.Leu490Thrfs*10) . This is the first report of splice-site mutation of STAG3 gene causes POI in 2 Han Chinese patients.

Abstract
Objective: To evaluate whether early postoperative serum uric acid level can predict postoperative acute renal injury (AKI) among patients undergoing coronary artery bypass grafting (CABG). Methods: The study retrospectively enrolled 1 306 patients undergoing CABG in Fuwai Hospital between September 2012 and December 2013. The patients were divided into 5 groups by the concentrations of serum uric acid measured on the morning of the first postoperative day, and uric acid categories were as follow: less than 195 μmol/L (Q1 group, 262 cases), 195-236 μmol/L (Q2 group, 263 cases), 237-280 μmol/L (Q3 group, 260 cases), 281-336 μmol/L (Q4 group, 261 cases), more than 336 μmol/L (Q5 group, 260 cases). The primary end points were AKI (RIFLE criteria), severe AKI (AKI≥stage Ⅰ), postoperative continuous renal replacement therapy (CRRT) requirement, in-hospital death, length of stay in hospital and intensive care unit(ICU). The area under the receiver-operating characteristic (ROC) curve (AUC) was used to determine the ability of the early postoperative serum uric acid level as a risk factor for postoperative AKI prediction. Results: Among the 1 306 patients enrolled in the study, AKI was found in 335 patients (25.65%). After adjusting for variables that were different between the 5 groups, the Q5 group had significantly higher risk of AKI, AKI≥ stage Ⅰ and the requirement of CRRT (P<0.01). The ROC for the outcome of postoperative AKI had an AUC of 0.648 (95% CI: 0.612-0.683) when serum creatinine levels alone were used and 0.722 (95% CI: 0.688-0.755) when serum uric acid levels alone were used (both P<0.001). Early postoperative serum uric acid was a better predictor than serum creatinine(P<0.001). Conclusion: The serum uric acid concentration within 12 hours after operation is an independent predictor of postoperative AKI in patients undergoing CABG, which could be used to identify patients at high risk for AKI.

Abstract
To improve the differential diagnosis of sellar region mass, 4 cases with sellar mass and misdiagnosed as lymphocytic hypophysitis (LYH) were reviewed retrospectively.The 4 patients (2 male and 2 female) aged 20-60 years old were all presented with symptoms of headache, polydipsia and polyuria.Biochemical studies confirmed the diagnoses of central diabetes insipidus and hypopituitarism.Head MRI scans showed LYH like image for all the cases, and, thus, high dose methylprednisolone pulse therapy (HDMPT) was applied to the patients.Their symptoms deteriorated and the sellar mass enlarged after a short period of partial improvement.Operations were performed in all the patients.Histology study showed craniopharyngioma with abscess, primary abscess, secondary hypophysitis caused by Wegener's granulomatosis, and germinoma with secondary hypophysitis, respectively.In conclusion, surgery or biopsy is necessary for those who presented with sellar region mass and was suspected to be with LYH, but with poor response or even worse after HDMPT.

Abstract
BACKGROUND AND PURPOSE Skull base chordoma has been widely studied in recent years, however, imaging characteristics of this tumor have not been well elaborated. The purpose of this study was to establish an MR imaging grading system for skull base chordoma. MATERIALS AND METHODS In this study, 156 patients with skull base chordomas were retrospectively assessed. Tumor-to-pons signal intensity ratios were calculated from pretreatment MR images RT1 (ratio of tumor to pons signal intensity in T1 FLAIR sequence), RT2 (ratio of tumor to pons signal intensity in T2 sequence) and REN (ratio of tumor to pons signal intensity in enhanced T1 FLAIR sequence), and significant ratios for overall survival and progression-free survival were selected to establish a grading system. Clinical variables among different MR imaging grades were then analyzed to evaluate the usefulness of the grading system. RESULTS RT2 (P < .001) and REN (P = .04) were identified as significant variables affecting progression-free survival. After analysis, the classification criteria were set as follows: MR grade I, RT2 > 2.49 and REN ≤ 0.77; MR grade II, RT2 > 2.49 and REN > 0.77, or RT2 ≤ 2.49 and REN ≤ 0.77; and MR grade III, RT2 ≤ 2.49 and REN > 0.77. MR grade III tumors had a more abundant tumor blood supply than MR grade I tumors (P < .001), and the intraoperative blood loss of MR grade III tumors was higher than that of MR grade I tumors (P = .002). Additionally, skull base chordoma progression risk increased by 2.071 times for every single MR grade increase (P < .001). CONCLUSIONS A higher RT2 value was a negative indicator of tumor progression, whereas a higher REN value was a positive risk factor of tumor progression. MR grade III tumors showed a more abundant blood supply than MR grade I tumors, and the risk of skull base chordoma progression increased with every single MR grade increase.

Abstract
Bank plant systems provide effective biological control for pests infesting commercially important crops. Aphids cause physical damage to crops by feeding on the leaves, as well as transmitting damaging viral diseases. To develop a bank plant system to control aphids that damage vegetable crops, we initially reared the parasitoid Aphelinus albipodus (Hayat and Fatima) on the soybean aphid, Aphis glycines (Matsumura) reared on the soybean plant, Glycine max (L.) that was elected as the alternate host. Parasitoid adults that emerged from A. glycines were allowed to parasitize second instar nymphs of the aphid Myzus persicae (Sulzer) which were reared on sweet pepper and chili pepper leaves. The results showed that A. albipodus females feeding and parasitizing M. persicae nymphs reared on sweet pepper lived for 18.9 days, with an average fecundity of 337.3 progenies/female, while females feeding and parasitizing on M. persicae nymphs reared on chili pepper lived for 18.8 days, with an average fecundity of 356.2 progenies/female. There were no significant difference in the development time and reproduction of A. albipodus individuals parasitizing M. persicae nymphs reared on sweet pepper and chili pepper plants. The intrinsic rate of increase (r), net reproductive rate (R 0), net aphid killing rate (Z 0), and finite aphid killing rate (θ) of A. albipodus parasitizing sweet pepper and chili pepper M. persicae was 0.2258 days-1, 171.7 progeny adults, 222.6 aphids, and 0.4048 and 0.2295 days-1, 191.8 progeny adults, 243.3 aphids, and 0.4021, respectively. Our results suggested that A. glycines could serve as an effective alternative host for supporting A. albipodus against M. persicae infesting sweet pepper and chili pepper.

Abstract
OBJECTIVE To explore the protective function of vitamin D (VD)/vitamin D receptor (VDR) on the development of oral lichen planus (OLP) and elaborate the underling mechanism of it. METHODS H&E staining, myeloid peroxidase (MPO) assays, quantitative PCR (qPCR), Western blotting, and Elisa were used to test the human biopsies and serum. QPCR, Western blotting, Elisa, and siRNA transfection were also performed in LPS-induced keratinocytes to observe the functions of vitamin D and VDR. RESULTS The lack of VDR in the diseased biopsies from OLP patients was associated with activated helper T-cell type 1 (Th1)-driven inflammatory response. Importantly, the status of serum 25-hydroxyvitamin D of OLP patients was reduced consistently. In a cultured cell model, 1,25(OH)2 D3 could downregulate excessive production of pro-inflammatory factors induced by lipopolysaccharide (LPS) in keratinocyte HaCat cells. Mechanistically, even though LPS-induced cytokines in keratinocytes were inhibited both by nuclear factor-κB (NF-κB) inhibitor and by activator protein 1 (AP-1) inhibitor, VDR-dependent 1,25(OH)2 D3 blocked the activation of phosphorylated-NF-κB p65 rather than c-Jun/c-Fos in the presence of LPS stimulation. CONCLUSION These results suggest that 1,25(OH)2 D3 plays an anti-inflammatory role in OLP by mediating NF-κB signaling pathway but not AP-1 signaling pathway with a VDR-dependent manner, predicting vitamin D supplement may be a potential strategy for the OLP management.

Abstract
OBJECTIVE To summarize ultrasound features associated with medullary thyroid carcinoma (MTC) and investigate the predictive value of ultrasonography in preoperative diagnosis of MTC. METHODS The sonographic and clinical data were studied in a series of nodules histologically proven as MTC collected from January 1993 to January 2013. RESULTS A total of 86 patients (92 nodules proven as MTC) were enrolled in the study with an average age of (47±12) years.Among the MTCs, 21.7%(20/92) were excluded because of missing data and the remained 78.3%(72/92) had complete data with the average diameter of (2.1±1.3) cm.The common US findings for MTC were solid, hypoechogenicity, regular sharp, well-defined margin, AP/ TR<1 and calcification (mostly microcalcification). Calcification and vascularization were more common in MTC nodules(48.6% vs 5.6%, P=0.001). Nodules with enlargement of cervical lymph node tended to be undergone FNAB(76.0% vs 55.3%, P=0.084), and ill-defined margin was more common in MTC nodules with cervical lymph node metastasis(36.4% vs 12.8%, P=0.009). CONCLUSION Despite having a few US features closely linked to the malignant nodules such as solid, hypoechogenicity and with microcalcification, the MTC nodules also have specific US imaging characteristics as regular sharp, well-defined margin and AP/ TR<1.

Abstract
A 3.5 nm amorphous CoFeB film was sputtered on GaAs (001) wafer substrate without applying magnetic field during deposition, and a significant in-plane uniaxial magnetic anisotropy (UMA) field (Hu) of about 300 Oe could be achieved. To precisely determine the intrinsic Gilbert damping constant (α) of this film, both ferromagnetic resonance (FMR) and time-resolved magneto-optical Kerr effect (TRMOKE) techniques were utilized. With good fitting of the dynamic spectra of FMR and TRMOKE, α is calculated to be 0.010 and 0.013, respectively. Obviously, the latter is 30% larger than the former, which is due to the transient heating effect during the TRMOKE measurement. In comparison with ordinary amorphous CoFeB films with negligible magnetic anisotropies, α is enhanced significantly in the CoFeB/GaAs(001) film, which may be mainly resulted from the enhanced spin-orbit coupling induced by the CoFeB/GaAs interface. However, the significant in-plane UMA plays minor role in the enhancement of α.

Abstract
OBJECTIVE 5-Aminolevulinic acid photodynamic therapy (5-ALA-PDT) for condylomata acuminate (CA) is effective and safe, but how this treatment affects immune reaction is poorly understood. We aimed to explore the effects of PDT on local immunity in CA. PATIENTS AND METHODS Immunohistochemical analysis before and after PDT was performed to analyze local changes in the distribution of T lymphocytes, CD123+ plasmacytoid dendritic cells (pDCs) and CD1a+ myeloid DCs. Quantitative Real-time PCR (qRT-PCR) was used to detect changes in mRNA levels of interferon (IFN), ISG-15, Mx-2, TLR9, and IRF7. RESULTS Compared to the healthy foreskin, tissue from patient showed increased CD3+ and CD8+ cells but no significant changes in CD4+ cells or CD123+ pDCs, and a significantly decreased CD1a+ Langerhans cells (LCs). Twenty-four hours after a PDT session, local CD3+, CD4+, and CD123+ pDCs in lesions significantly increased and migrated to the superficial dermis. CD1a+ LCs in the epidermis gradually decreased, while DCs gradually increased. The number, distribution, and morphology of CD8+ cells did not change after a PDT session. The mRNA expressions of IFN-γ, IFN-α, IFN-β, ISG-15, Mx-2, TLR9, and IRF7 were all elevated. As compared to the patients without significantly increased IFN-a and IFN-b after a PDT session, patients with significant increases needed fewer sessions of PDT for a cure. CONCLUSIONS These results suggest that PDT for CA can activate T-lymphocyte-meditated immunity, and pDC-related immunity is also activated. The clinical efficacy of 5-ALA-PDT against CA may be related to the increased IFN-α and IFN-β after treatment.

Abstract
OBJECTIVE To evaluate the impacts of high glucose on the repair function of kidney stem cells (KSC) conditional medium to the hypoxia-injured renal tubular epithelium cells (RTEC). METHODS KSC were isolated from the renal papilla in 4-week-Sprague-Dawley rats. The KSC were pretreated in media with high glucose (30 mmol/L) or with normal glucose (5.6 mmol/L), respectively. The supernatants of the pre-treated KSC were collected as the conditional media. The hypoxia/reoxygenation (H/R) model of rat RTEC was established using the NRK-52E cell line. The effects of KSC conditional media on the H/R RTEC were investigated. RESULTS (1) The best H/R model of RTEC was established using hypoxia for 4 h and reoxygenation 2 h. (2) After hypoxia, the early and late cell apoptosis rates of the H/R RTEC were increased. The H/R RTEC were co-cultured with KSC conditional media for 12 h and 24 h, respectively. The H/R RTEC were co-cultured with DMEM/F12 as a control group. The cell apoptosis rate of H/R RTEC was lower after co-cultured with KSC conditional media (P<0.01), and the cell apoptosis rate of H/R RTEC in high glucose group was much higher than that in normal glucose group after co-cultured 24 h (P=0.02). (3) After hypoxia, the lactic dehydrogenase (LDH) and malondialdehyde (MDA) levels of the H/R RTEC supernatant were increased, and the superoxide dismutase (SOD) level decreased. The LDH and MDA levels were lower and the SOD level was higher after co-cultured with KSC conditional media for 12 h and 24 h, respectively (P<0.01). The LDH and MDA levels of H/R RTEC supernatant were much higher in the high glucose group than in the normal glucose group (P<0.05), and the SOD level of H/R RTEC supernatant was much lower in the high glucose group than in the normal glucose group (P<0.01). CONCLUSION KSC conditional media could repair the H/R injury of RTEC. The effects were mainly by inhibiting cell apoptosis, and reducing oxidative stress; the anti-cell apoptosis ability and the anti-oxidative stress capacity of the conditional medium were reduced after KSC were pre-treated with high glucose.

Abstract
INTRODUCTION Detection of recurrent genetic abnormalities is of great significance for a refined diagnosis and assessment of prognosis in leukemia. Conventional nested reverse transcription PCR is labor intensive and time-consuming. METHODS We have developed a novel dual-color TaqMan probe-based real-time PCR method for the simultaneous screening of 45 fusion transcripts in 12 parallel reactions. The method was tested and validated with cell lines carrying known fusion transcripts and patient samples. RESULTS A multiplex real-time PCR method was successfully developed for rapid detection of 45 fusion genes and validated for 15 of the more commonly detected fusion genes. Intra-assay reproducibility assessed for the most frequent rearrangements ranged from 0.41% to 0.74% for the coefficient of variation (CV) of cycle threshold (Ct) and the interassay reproducibility ranged from 1.62% to 2.83% in five separate experiments. The lowest detection limit for the translocations tested ranged between 1 : 16 000 and 1 : 32 000. Validation of the method with 213 patient samples showed 100% specificity and excellent consistence with conventional nested RT-PCR. CONCLUSION Overall, we believe that this method is easily applicable, cost-effective, and clinically useful for a rapid screening of fusion genes in the initial diagnostic phase of leukemia. Its use can also be extended to the monitoring of minimal residual disease.

Abstract
OBJECTIVE To fill up the absence of data on causes of death of urban residents in Beijing during 1965-1974 and provide evidence for the similar study in other areas. METHODS All possible sources for death data during 1965-1974 were identified through expert consultations and record search. Stratified sampling was conducted to collect the death data of urban residents during this period in Beijing. The mortality rate, death cause constituent and rank of death causes were used in this descriptive analysis. RESULTS A total of 11 668 records of deaths from 1965 to 1974 were collected from 10 local police stations in urban area of Beijing. The top 10 death causes in the urban residents were heart disease, tumor, cerebrovascular disease, accidental injury, respiratory system disease, digestive system disease, communicable disease and parasitic disease, nervous system disease, urogenital and reproductive system disease, endocrine and nutrition metabolic diseases. The deaths caused by these diseases accounted for 84.19% of the total deaths. Accidental injury accounted for 13.22% of the total deaths, which was significantly higher than that in either 1964 or 1975, two years before and after this period(P<0.01). Suicide accounted for 54.47% of the total accidental injury deaths. For men, accidental injury was the leading death cause, followed by cancer and heart disease; for women, heart disease, cancer and cerebrovascular disease were the top three death causes. CONCLUSION The major death cause in urban residents changed from infectious diseases to chronic and non-communicable diseases during 1965-1974. A remarkable high proportion of deaths caused by accidental injury was due to the historical background during that period in Beijing, China.

Abstract
A highly integrated, high performance, and re-configurable device, which is designed for the Nitrogen-Vacancy (N-V) center based quantum applications, is reported. The digital compartment of the device is fully implemented in a Field-Programmable-Gate-Array (FPGA). The digital compartment is designed to manage the multi-function digital waveform generation and the time-to-digital convertors. The device provides two arbitrary-waveform-generator channels which operate at a 1 Gsps sampling rate with a maximum bandwidth of 500 MHz. There are twelve pulse channels integrated in the device with a 50 ps time resolution in both duration and delay. The pulse channels operate with the 3.3 V transistor-transistor logic. The FPGA-based time-to-digital convertor provides a 23-ps time measurement precision. A data accumulation module, which can record the input count rate and the distributions of the time measurement, is also available. A digital-to-analog convertor board is implemented as the analog compartment, which converts the digital waveforms to analog signals with 500 MHz lowpass filters. All the input and output channels of the device are equipped with 50 Ω SubMiniature version A termination. The hardware design is modularized thus it can be easily upgraded with compatible components. The device is suitable to be applied in the quantum technologies based on the N-V centers, as well as in other quantum solid state systems, such as quantum dots, phosphorus doped in silicon, and defect spins in silicon carbide.

Abstract
OBJECTIVE To investigate the relationship between the gene polymorphism of osteoprotegerin (OPG) and bone mineral density (BMD) in hemodialysis patients. PATIENTS AND METHODS A total of 147 patients with end-stage renal disease (ESRD) who were admitted to the Weifang People's Hospital for maintenance hemodialysis between January 2014 and December 2015 were enrolled. Peripheral blood was collected from the subjects for assay of the polymorphism of A163G and G1181C loci of OPG. The measurements of the levels of RANK, RANKL, TNF-α, IL-6, PINP, CTX-I, CTX-II and TRACP5 in the isolated serum were taken. RESULTS For the polymorphism of A163G locus on the OPG gene, the BMDs of left femoral neck and lumbar poster anterior L1-L4 of the AA genotype were significantly higher than those of the AG and GG genotypes. There was no significant difference in comparison of BMDs at the forearm (distal 1/3) between the AA genotype and AG and GG genotypes. No significant differences were found in the comparison of BMDs at all sites between AG and GG genotypes. The serum level of RANKL of the AA genotype was significantly higher than levels of AG and GG genotypes, but the levels of RANK, TNF-α, IL-6, PINP, CTX-I, CTX-II and TRACP5 were prominently lower than those levels of AG and GG genotypes. For the polymorphism of G1181C locus on the OPG gene, the BMDs of left femoral neck and lumbar poster anterior L1-L4 of the CC genotype were significantly higher than the BMDs of GG and GC genotypes, There was no significant difference in the comparison of BMDs at the forearm (distal 1/3) between the CC genotype and GG and GC genotypes. No significant differences were found in the comparison of BMDs at all sites between GG and GC genotypes. The serum level of RANKL of the CC genotype was significantly higher than the level of GG and GC genotypes. However, the levels of RANK, TNF-α, IL-6, PINP, CTX-I, CTX-II and TRACP5 were prominently lower than those levels of GG and GC genotypes. CONCLUSIONS The polymorphisms of A163G and G1181C loci on the OPG gene were correlated with the BMD of hemodialysis patients. The genotype AA of A163G and genotype CC of G1181C were identified as the protective factors for BMD.

Abstract
Objective: To analyze the clinical features and outcomes of congenital adrenal hyperplasia (CAH) with adenomatoid adrenal gland. Methods: Nineteen patients clinically confirmed as CAH with adenomatoid adrenal gland, from 2008 to 2015 in Deparment of Endocrinology of Chinese PLA General Hospital, were retrospectively analyzed, and the outcomes of the treatment were followed up. Results: Seventy-six patients were clinically confirmed as CAH, from 2008 to 2015 in PLA hospital. Nineteen of them have accompanied with adenomatoid adrenal gland. Of the 19 confirmed cases, 7 were male, and 12 were female. The mean age was (33.3±14.8) years old. Nineteen confirmed cases were consisted of 10 cases of 21-hydroxylase deficiency (OHD), 6 cases of 17α-OHD, and 3 cases of 11β-OHD. Of the 19 cases, 5 cases presented with adrenal hyperplasia with left side adenomatoid solid lesion, 2 cases presented with adrenal hyperplasia with right side adenomatoid solid lesion, and 8 cases presented with double side adenomatoid solid lesion. The proportion of adrenal hyperplasia with unilateral cystic or calcified changes was 21.1%. Nine of the 19 patients underwent operation or fine needle biopsy. The pathology showed 7 adenomas (21-OHD/17α-OHD 5/2) and 2 myelolipomas (21-OHD/17α-OHD 1/1). Four patients were admitted into hospital because of the incidentaloma, while others because of the clinical symptoms. The average follow-up time was 31 months. CT images were rechecked among 7 patients. After the treatment, 1 patient's tumor shrunk, 4 cases had no recurrence, 1 case's tumor disappeared, and the other one case had no change. Symtoms of eleven followed-up patients relieved. Conclusions: The image of adrenal of CAH with adenomatoid adrenal gland is various. It may occur in each type of CAH presented as unilateral or bilateral, adenoma or myelolipoma.
