Abstract
Objective: To establish an ultra-high performance liquid chromatography method for the determination of mifepristone in the air of workplaces. Methods: From January to July 2018, glass fiber filter membrane was used to collect mifepristone in the workplace air, eluted with acetonitrile/water solution, and determined by ultra-high performance liquid chromatography-UV method. Results: The detection limit of mifepristone determination method was 0.005 μg/ml, the lower limit of quantification was 0.015 μg/ml, and the lowest detection concentration was 0.14 μg/m(3) (calculated by collecting 75 L air samples) . The concentration of mifepristone has a good linear relationship between 0.015-40.24 μg/ml, r=0.9999. The accuracy and elution efficiency of the method were calculated based on the recovery rate, ranging from 92.7% to 100.0%. The average sampling efficiency was 99.6%-100.0%. The intra-assay precision of the method was 0.92% to 5.41%, and the inter-assay precision was 0.89% to 6.25%. The sample could be stored stably for 3 days at 4°C. Conclusion: The ultra-high performance liquid chromatography method for determination of mifepristone is easy to operate, and its indicators meet the requirements of GBZ/T 201.4-2008 "Guidelines for the Establishment of Occupational Hygiene Standards Part 4: Methods for Determination of Chemical Substances in Workplace Air", which is suitable for the detection of mifepristone in the air of the workplace.

Abstract
OBJECTIVES The West China Health and Aging Trends study (WCHAT) is intended to focus on the research that will guide efforts to reduce disability, maximize health and independent functioning, and enhance quality of life at older ages in different ethnicities. And provide the basis for understanding trends and dynamics in late-life functioning, how these differ in various ethnic subgroups, and the economic or social consequences of aging and disability in western China. PARTICIPANTS The cohort enrolled 7536 participants and 7439 participants aged 50 years and older in the baseline in 2018 and every year would be followed up. Finding to date: The data in WCHAT were prospectively collected from Yunnan, Guizhou, Sichuan and Xinjiang by 7 medical institutions. A number of age-related outcome measures were collected though corresponding geriatric assessments. Blood testing, saliva, urine and feces testing are available for all cohort participants. Future plans: The data in WCHAT can be used for various types of epidemiological research, particularly for examining how the culture specific life styles and diet influences geriatrics related outcomes. We are initially planning cohort studies and established a sample biobank in relation to the risk and prognosis of frailty, sarcopenia and other geriatric syndromes. Strengths and limitations of this study: It is a first multi-ethnic cohort study in West China that aimed to investigate the influence of culture specific life styles, diet and living environment on the prevalence of geriatric syndromes like frailty, sarcopenia and so on. This is a prospective multi-center observational study, which will be conducted in various ethnic groups gathering places. This study collected information that related to fatigue, falls, and cognition were obtained through self-reports, which might have recall bias and grouping errors. This study has problems such as the interviewees' refusal to visit, death, going out, and large population mobility may lead to high loss of visit rates. This study collected information from a comparatively healthier elderly population in which external validity was limited.

Abstract
OBJECTIVES To determine the risk of poor health-related outcomes in older adults with cooccurring hearing impairment and cognitive impairment, and to compare the risk of hearing impairment only, cognitive impairment only, and multiple morbidities. DESIGN Cross-sectional study. SETTING Community-dwelling older adults aged 60 years and older were included. PARTICIPANTS The data of missing hearing and cognitive status were excluded, and 3770 older people participated in the study. MEASUREMENTS The hearing function evaluation was conducted by questionnaire survey. Assessment of cognitive function was completed using the SPMSQ scale. The subjects were divided into hearing impairment and cognitive impairment group, hearing impairment only group, cognitive impairment only group and neither group. Multiple logistic regression was used to analyze the risks of hearing and cognitive impairment and health-related condition. RESULTS The prevalence of hearing impairment and cognitive impairment, hearing impairment only, cognitive impairment only, and neither were 9.4%, 8.3%, 29.9% and 52.4%, respectively. Compared with the control group, the individuals with hearing impairment and cognitive impairment were associated with depression (OR=3.48, 95% CI=2.66, 4.56), anxiety (OR=2.35, 95% CI=1.92, 3.33), frailty (OR=4.30, 95% CI=2.89, 6.40), and ADL impairment (OR=2.77, 95% CI=2.03, 3.77). CONCLUSION The studies shows that hearing impairment combined with cognitive impairment is significantly associated with anxiety, depression, frailty, and ADL impairment. Comprehensive management and intervention should be provided for older people to reduce the occurrence of adverse health consequences.

Abstract
Objective: To investigate the correlation between tissue oxygen saturation during one lung ventilation and postoperative neuro cognitive dysfunction (PND) in elderly patients in thoracic surgery. Methods: One hundred and twenty-eight elderly patients who underwent selective lobectomy from August 2017 to September 2018 in the Forth Hospital of Hebei Medical University were enrolled. The patients were divided into PND group (n=34) and non-PND group (n=94) according to whether PND occurred 3 days after surgery. Tissue oxygenation was monitored at bilateral forebrain, brachioradialis muscle and quadriceps. Cognitive function was assessed by the Montreal Cognitive Assessment (MoCA) at baseline and the third day after the operation. Postoperative cognitive dysfunction was diagnosed if postoperative MoCA decreased at least 2 scores compared with preoperative baseline value. Outcomes included the incidence of PND, the incidence of tissue oxygen desaturation during one lung ventilation, postoperative complications within 30 days and length of postoperative in-hospital stay. Logistic regression was used to screen independent risk factors of PND. Results: The incidence of postoperative cognitive dysfunction was 26.6% (34/128). The two groups had no significant difference in the incidence of non-neurogenic complications (new occurred arrhythmia, pulmonary infection, pulmonary embolism, acute renal insufficiency, sepsis, deep vein thrombosis, all P>0.05). However, the length of postoperative in-hospital stay of PND group was 7.0 (6.0, 8.5) d, which was longer than that of non-PND group [6.0 (5.0, 8.0) d]. There was significant difference (U=2.394, P=0.017) . There was no correlation between the two groups within the minimum of SmtO(2) in upper limbs (OR=0.988, 95%CI: 0.954-1.024, P=0.519) and the range of desaturation (OR=1.010, 95%CI: 0.979-1.042, P=0.514) , as well as the minimum of SmtO(2) in legs (OR=0.996, 95%CI: 0.961-1.032, P=0.832) and the range of desaturation (OR=0.997, 95%CI: 0.971-1.025, P=0.851) . Multivariate logistic regression analysis showed that the high ASA grade (OR=2.617, 95%CI: 1.112-6.157, P=0.029) and the minimum of cerebral oxygen saturation during one lung ventilation (OR=0.931, 95%CI: 0.880-0.986, P=0.014) were independent risk factors of PND. There was no statistical correlation between muscle oxygen saturation and PND. Conclusion: Cerebral desaturation during one lung ventilation increased the risk of PND in elderly patients, while the muscle desaturation has no statistical correlation with PND.

Abstract
Objective: To evaluate the clinical value of ultrasound attenuation parameters (UAP) in diagnosing the liver steatosis degree in patients with chronic liver disease, and to explore the relevant factors that affect UAP detection values. Methods: 130 cases with chronic liver disease diagnosed as liver steatosis by liver biopsy during January 2014 to May 2019 were selected from the Hepatology Department of Integrated Traditional Chinese and Western Medicine of the Third Hospital of Hebei Medical University. UAP and liver stiffness (LSM) were detected by iLivTouch, and the body mass index (BMI) was calculated. Simultaneously, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltransferase (GGT), total bilirubin (TBil), triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL) levels and peripheral platelet (PLT) counts were measured. The correlation between UAP and liver steatosis was analyzed based on the liver histopathological results. SPSS 21.0 statistical software was used for statistical analysis. Receiver operating characteristic curve (ROC) was used to analyze the accuracy and specificity of UAP in the diagnosis of liver steatosis in patients with chronic liver disease. Spearman's rank correlation analysis was used to study the relevant factors affecting UAP value. Results: The histopathological changes of liver biopsy showed that there were 43 cases of grade F1, 47 cases of F2, 32 cases of F3 and 8 cases of F4. UAP and BMI (r = 0.363, P < 0.001), and UAP and liver steatosis degree (r = 0.380, P < 0.001) were positively correlated. BMI and the liver steatosis degree were independent predictors of UAP value. The cut-off points for UAP to diagnose liver steatosis degree were 276 dB/m for F≥2, 288 dB/m for F≥2, 293 dB/m for F≥3, and F = 4, respectively. The sensitivity and specificity was 0.379, 0.500, 0.750, and 0.930, 0.922, 0.836, respectively. Conclusion: Ultrasonic attenuation parameters cannot only determine the presence or absence of liver steatosis in patients with chronic liver disease, but also can better assess the liver steatosis degree.

Abstract
OBJECTIVE The aim of this study was to investigate the role of the insulin-like growth factor-1 receptor (IGF-1R)/β-catenin signaling axis in bone impairment induced by hyperglycemia in ovariectomized rats. METHODS Rats were divided into four groups. The sham group received sham operation and a single intraperitoneal administration of vehicle. The ovariectomy (OVX) group was subjected to bilateral OVX and vehicle injection. The streptozotocin (STZ) group received sham operation and a single STZ injection to induce hyperglycemia. The OVX + STZ group received bilateral OVX and a single STZ injection. Dual-energy X-ray absorptiometry measurement, bone biomechanics test, micro-computed tomography scan, and hematoxylin-eosin staining were performed to evaluate bone alteration in this model. The expression of relevant signals including IGF-1R, glycogen synthase kinase-3β (GSK-3β), and β-catenin were examined by quantitative real-time polymerase chain reaction and western blot. RESULTS The OVX, STZ, and OVX + STZ groups induced bone loss, attenuated bone strength, and impaired microarchitecture compared with the sham group, respectively. Compared with OVX, more serious bone damage was found in the OVX + STZ group, which showed enhanced phosphorylation of IGF-1R, GSK-3β, and β-catenin. CONCLUSION OVX plus STZ induced more serious bone impairment than OVX alone, which involves the IGF-1R/β-catenin signaling axis in the pathogenesis. This may provide a potential target for treatment of postmenopausal diabetic osteoporosis.

Abstract
OBJECTIVE To explore the role of phospholipase C epsilon 1 (PLCE1) in regulating cell apoptosis of non-small cell lung cancer (NSCLC) and its underlying mechanism. PATIENTS AND METHODS The mRNA and protein levels of PLCE1 in NSCLC tissues, adjacent normal tissues and NSCLC cell lines (A549 and H1299) were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and Western blot, respectively. Methylation status in the promoter region of PTEN in NSCLC cells was accessed using the relative commercial kit. Cell apoptosis after transfection of PLCE1 siRNA in NSCLC cells was detected by flow cytometry. Protein expressions of apoptosis-related genes in NSCLC cells after altering PLCE1 expression were detected by Western blot. RESULTS PLCE1 was highly expressed in NSCLC tissues and cell lines than that of controls. PLCE1 knockdown promoted PTEN expression and inhibited methylation in H1299 cells. Transfection of PLCE1 siRNA in NSCLC cells remarkably induced cell apoptosis. CONCLUSIONS PLCE1 inhibits cell apoptosis of NSCLC by promoting PTEN methylation.

Abstract
Ischemic stroke is the leading cause of human disability and mortality in the world. Neuroinflammation is the main pathological event following ischemia which contributes to secondary brain tissue damage and is driven by infiltration of circulating immune cells such as macrophages. Because of neuroprotective properties against ischemic brain damage, estrogens have the potential to become of therapeutic interest. However, the exact mechanisms of neuroprotection and signaling pathways is not completely understood. In the current study, 12-week-old male Wistar rats underwent an experimental ischemia by occluding the middle cerebral artery transiently (tMCAO) for 1 h. Male rats subjected to tMCAO were randomly assigned to receive 17β-estradiol or vehicle treatment. The animals were sacrificed 72 h post tMCAO, transcardially perfused and the brains were proceeded either for TTC staining and gene analysis or for flow cytometry (CD45, CD11b, CD11c, CD40). We found that 17β-estradiol substitution significantly reduced the cortical infarct which was paralleled by an improved Garcia test scoring. Flow cytometry revealed that CD45+ cells as well as CD45+CD11b+CD11c+ cells were massively increased in tMCAO animals and numbers were nearly restored to sham levels after 17β-estradiol treatment. Gene expression analysis showed a reperfusion time-dependent upregulation of the markers CD45, CD11b and the activation marker CD40. The reduction in gene expression after 72 h of reperfusion and simultaneous 17β-estradiol substitution did not reach statistical significance. These data indicate that 17β-estradiol alleviated the cerebral ischemia-reperfusion injury and selectively suppressed the activation of the neuroinflammatory cascade via reduction of the number of activated microglia or infiltrated monocyte-derived macrophages in brain.

Abstract
Objective: To study the bacterial pathogen, the optimal plan of antibacterial drugs and the prognostic factors in patients with liver cirrhosis combined with bacterial pneumonia. Methods: Data of 324 cases with liver cirrhosis from the Department of Traditional and Western Medical Hepatology, the Third Hospital of Hebei Medical University were collected, including 217 cases of bacterial pneumonia. Baseline characteristics of the patients, factors affecting the efficacy of antibacterial treatment and prognosis were compared and analyzed. Logistic regression analysis was used to screen and predict the antibacterial efficacy indicators and a prediction model was established. Receiver operating characteristic curve was used to evaluate the value of the established model and Child-Turcortte-Pugh, model for end-stage liver disease, and model for end-stage liver disease combined with serum sodium concentration predict the therapeutic efficacy. Results: Chronic HBV and HCV infections were the main causes of cirrhosis, followed by cryptogenic cirrhosis and alcoholic cirrhosis. Diabetes, cardio-cerebrovascular and chronic obstructive pulmonary disease were susceptible factors for bacterial pneumonia. As infection occurred, the ratio of neutrophils to lymphocytes, serum C-reactive protein, procalcitonin, alanine aminotransferase, and total bilirubin levels had increased significantly. The results of pathogenic analysis showed that the top three pathogenic bacteria were Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Staphylococcus aureus. The resistance rate of Klebsiella pneumoniae to ceftriaxone was 50.0%, and that of ceftazidime, cefepime, and cefoperazone sulbactam were 27.8%. Imipenem and piperacillin tazobactam containing β-lactamase inhibitors were the most effective antibacterial therapies. Regression analysis showed that age, procalcitonin, and albumin was significantly correlated with antibacterial effects. The PAA model was established and had predicted the efficacy of Child-Turcortte-Pugh, model for end-stage liver disease, and model for end-stage liver disease combined with serum sodium. The specificity and sensitivity of the PAA was confirmed to be 94.12% and 93.62%, which was significantly higher than other models. Conclusion: The main common pathogenic bacterium of cirrhosis combined with bacterial pneumonia is Klebsiella pneumonia (G-bacilli). In addition, gram positive cocci (Staphylococcus aureus) and other are also visible. The elderly, diabetics and patients using hormones are prone to secondary fungal infections. Age, procalcitonin and serum albumin can accurately predict the antibacterial effect, guide clinical treatment and judge the prognosis of the established PAA model.

Abstract
BACKGROUND Ocular involvement can occur at any stage of syphilis. Prompt diagnosis and proper treatment of ocular syphilis are vital to avoid long-term consequences. OBJECTIVES To describe the risk factors for ocular syphilis and clinical features of blindness caused by syphilis. METHODS We report risk factors for ocular syphilis amongst patients seen at the Shanghai Skin Disease Hospital between October 2009 and October 2017. We identify patients with ocular syphilis resulting in blindness and report the clinical characteristics, laboratory findings and treatment outcomes of these patients. RESULTS A total of 8310 new cases of syphilis were seen, of which 213 patients had ocular disease and 50 patients had blindness due to syphilis. Increasing age and higher RPR titres were associated with ocular involvement but there was no association with HIV status. Blindness in syphilis was restricted predominantly to patients with optic nerve involvement and not patients with isolated uveitis. Fifty patients (and a total of 67 eyes) met the WHO definition of blindness prior to treatment for syphilis. At the end of follow-up, vision had improved in 24 of 67 eyes (35.8%) after treatment. Successful treatment of uveitis was associated with the best improvement in visual acuity, whilst patient with underlying optic atrophy prior to treatment had the worst visual outcome. CONCLUSIONS Ocular involvement is an important manifestation of syphilis which may result in blindness. Our data demonstrate outcomes for ocular syphilis are poor if detected late; early recognition and diagnosis is therefore vital to avoid permanent visual loss.

Abstract
Objective: To investigate the expression of IGF1R-Ras and RAGE-HMGB1 signaling pathways in colorectal cancer patients with type 2 diabetes mellitus and their significance. Methods: The resected cancer tissues were obtained from 59 patients with colorectal cancer (CRC), including 29 patients with type 2 diabetes mellitus (CRC/DM group) and 30 with CRC alone (CRC group). The expressions of IGF1R, Ras, RAGE and HMGB1 in cancer tissues were detected by immunohistochemistry. The differences between the two groups were compared and the relationship between the expression and clinicopathological characteristics was analyzed. Results: In CRC/DM group, the positive rates of IGF1R and Ras were both 65.5% (19/29), and 51.7% (15/29) patients had IGF1R+ Ras+ immunophenotype, which were significantly higher than those in CRC group [33.3% (10/30), 36.7% (11/30) and 20.0% (6/30); P=0.013, 0.027 and 0.011, respectively]. The expression of IGF1R and Ras in CRC / DM group was positively correlated (r=0.479, P=0.017). The positive rate of RAGE expression in CRC group and CRC/DM group was 70.0% (21/30) and 72.4% (21/29) respectively, and the positive rate of HMGB1 expression was 46.7% (14/30) and 58.6% (17/29) respectively, neither was observed with significant difference (P=0.358 and 0.838). However, the proportion of patients with RAGE+ HMGB1+ immunophenotype in CRC/DM group [55.2% (16/29)] was higher than that in CRC Group [26.7% (8/30)] which was statistically significant (P=0.026), and the expression of both proteins was positively correlated in CRC/DM group (r=0.578, P=0.003). The clinicopathological analysis showed that in both groups the expression of IGF1R, Ras, RAGE and HMGB1 had no correlation with the sex, age, differentiation degree, tumor length, T stage and lymph node metastasis (P>0.05). Conclusion: Both IGF1R-Ras and RAGE-HMGB1 pathways may be involved in the oncogenesis of colorectal cancer in patients with type 2 diabetes.

Abstract
Background:Refractory gout manifests as recurrent flares, chronic arthritis and progressive tophaceous deposits. Febuxostat is a widely-used potent serum urate-lowering reagent, but some gout patients cannot achieve target serum uric acid (sUA) after they used this reagent.Objectives:To determine whether febuxostat-resistance should be a criterion for refractory gout, characteristics of gout patients who were resistance to febuxostat or allopurinol were compared.Methods:This study was performed from December 2015 to December 2019. Medical records of gout patients who met the 2015 gout classification criteria [1] and undertook febuxostat (febuxostat group) or allopurinol (allopurinol group) urate-lowing therapy (ULT) were assessed. Dose of ULT was adjusted till sUA was below 6 mg/dL and 5 mg/dL for patients with urate deposition. We screened gout patients who had contraindication or history of failure to normalize sUA for≥ 3 months of treatment with the maximum medically appropriate febuxostat (febuxostat-resistance) or allopurinol (allopurinol-resistance) dose as defined by physicians. Furthermore, these screened patients met the traditional criteria of refractory gout except therapeutic reaction [2].Demography and clinical characteristics were recorded. Features between febuxostat-resistance and allopurinol-resistance patients were compared.Results:(1) Of 683 gout patients who were included, 516 and 167 of them used febuxostat or allopurinol. (2) Age (41.92±11.58 vs. 42.26±9.41 years), Male gender (97.50% vs. 97.01%), duration of gout (5.78±4.74 vs. 5.05±4.72 years) and sUA (6.30±2.50 vs. 6.67±2.14 mg/dL) were similar between febuxostat group and allopurinol group (P>0.05). (3) Dose of febuxostat or allopurinol were 47.28mg/day and 178.24mg/day. (4) Sixteen patients were febuxostat-resistance, while 6 patients were allopurinol-resistance. Prevalence rates of treatment resistance were comparable between groups (3.10% vs. 3.59%,P>0.05). (5) Some parameters were different between resistance patients and non-resistance patients in both groups (Table 1,P<0.05). However, characteristics of febuxostat-resistance and allopurinol-resistance patients were similar (P>0.05).Table 1Characteristics of gout patients in febuxostat group and allopurinol groupParametersFebuxostat GroupAllopurinol GroupNon-resistance(n=500)Resistance(n=16)Non-resistance(n=161)Resistance(n=6)Age (year)41.93±11.6541.67±9.5842.22±13.3344.50±16.98Male Gender (%)97.40100.0096.89100.00BMI (kg/m2)25.44±3.4626.22±3.4725.86±3.9725.60±6.42Duration of gout (years)5.75±4.767.00±3.97*4.96±4.737.75±2.62*Flares in previous 18 months (times)1.31±0.443.67±0.70*1.13±0.243.25±0.50*Presence of Tophi (%)23.80100.00*14.90100.00*Presence of Complication (%)35.8100.00*31.06100.00*sUA (mg/dL)6.21±2.479.13±1.24*6.42±2.3210.15±3.55*SCr (μmol/L)100.67±15.03163.96±29.41*96.93±22.91133.75±31.60*ESR (mm/L)24.59±19.2842.83±21.13*27.49±24.1056.50±28.12*CRP (mg/L)18.92±18.5928.81±23.85*23.12±22.6332.28±23.64**P<0.05 compared with non-resistance patients in the same group.BMIbody mass index,sUAserum uric acid,SCrserum creatinine,ESRerythrocyte sedimentation rate,CRPC-reactive proteinConclusion:Febuxostat-resistance is a potential criterion for refractory gout, because febuxostat-resistance patients shares similar characteristics of patients with refractory gout.References:[1]Neogi T, Jansen TL, Dalbeth N, et al. 2015 Gout classification criteria: an American College of Rheumatology/European League Against Rheumatism collaborative initiative.

Abstract
Background:The prevalence of gouty patients with ulcerations over tophi are increasing over time and it has been reported that gouty patients have significantly poor quality of life (QoL) compared to those healthy controls. [1, 2] there is no study on comparison of the QoL in patients with or without ulceration over tophi.Objectives:To compare the QoL in gout patients with or without ulcerations over tophi.Methods:A total of 79 inpatients with gout who were admitted to Guangdong Second Provincial General Hospital from January 2019 to January 2020 were included. Among them, ulcerations were identified in 28 patients. Short Form-36 Scales (SF-36) were chosen to assess patients. Differences between the groups were tested with Student’s t test or Mann-Whitney U test for continuous variables, and Chi-square tests for categorical variables.Results:Of 79 subjects, 74 were male, mean age was 54.23±14.3 years, disease duration was 10.94±7.06 years. Gouty patients had moderate- to high-quality levels in general health, vitality, social functioning, role emotional, and mental health (median: 65, 75, 75, 88, and88, respectively), while had low levels of quality in role physical, and bodily pain (median: 0, and 22, respectively). Patients presenting with ulcerations over tophi had worse scores on five SF-36 domains, the mental component summary (MCS) and the physical component summary (PCS) than gout patients without ulcerations [mean (SD); P < 0.05 for all]: Bodily pain, 30.86(31.59) vs 35.17(33.40); General health, 49.46(27.01) vs 64.17(23.69); Vitality, 57.14(32.53) vs 72.84(26.38); Mental health, 75.4(22.43) vs 83.05(20.96); Reported health transition, 3.58(0.89) vs 3.78(1.42); MCS, 52.62(21.82) vs 66.65(21.44); PCS, 35.85(21.17) vs 46.67(23.86).Conclusion:Patients with ulcerations over tophi present much worse QoL compared those without ulcerations.

Abstract
Background:Compliance to urate-lowering therapy (ULT) is poor in gout patients, which contributes to increased frequency of acute gout attacks, deposition of tophi and urate nephropathy [1]. Optimistic status is probably a potential and considerable factor affecting compliance to ULT in gout patients.Objectives:To compare optimistic status between gout patients and healthy controls, and also between gout patients with good and poor compliance. Relationship between optimistic status and compliance to ULT, sUA target achievement of gout patients were assessed as well.Methods:This was a monocentric and observational study which was performed from August 2018 to December 2019. Adult patients who met the 2015 gout classification criteria were included in this study. The healthy controls were individuals who were free of gout, hyperuricemia and other rheumatic diseases from the physical examination center of our hospital. Demographic data, including age, gender and education were collected from all individuals. Serum uric acid (sUA) were collected from gout patients at enrollment and again after 3 months. Disease duration of gout, visual analogue scale (VAS) of pain were also assessed for gout patients at enrollment. Compliance to ULT was measured using the medication possession ratio (MPR) in the following 3 months. Poor compliance was defined as MPR<0.8 and good compliance was defined as MPR≥0.8. All subjects completed the life orientation test-revised (LOT-R) for optimistic status assessment.Results:Five hundred and thirty gout patients and 307 healthy controls matched by age (41.4±12.3 vs. 42.1±9.3 years), gender (male 97.1% vs. 95.1%) and education (college graduated 54.2% vs. 58.0%) were included in this study. Of the 530 gout patients, the mean disease duration was 5.7±4.9 years, and 292 (55.1%) patients’ MPR were lower than 0.8. There was no statistic difference in LOT-R between gout patients and healthy controls (19.0±2.4 vs. 19.2±2.5, P>0.05) (Table 1). Gout patients with poor compliance (MPR<0.8) had higher level of sUA (525.5±138.0 vs. 471.2±152.5 μmol/L, P<0.05), followup sUA (450.1±154.5 vs. 361.6±120.0 μmol/L, P<0.05) and higher LOT-R (19.6±2.6 vs. 17.8±1.7, P<0.05) than those with good compliance (MPR≥0.8). Of the 292 gout patients with poor compliance, there were only 83 (28.4%) patients achieved sUA target after 3 months, and their LOT-R were significantly lower than those did not achieve sUA target (18.8±2.1 vs. 19.6±2.4, P<0.05). Finally, LOT-R correlated positively with sUA (r=0.131, P<0.05) and followup sUA (r=0.09, P<0.05), but negatively with MPR (r=-0.473, P<0.05) of gout patients (Table 2).Table 1Demographic and optimistic status of gout patients and healthy controlsVariablesGout patients(n=530)Controls(n=307)PAge (years)41.4±12.342.1±9.30.116Male gender, n (%)511 (96.4)292 (95.1)0.368College graduated, n (%)287 (54.2)178 (58.0)0.312LOT-R19.0±2.419.2±2.50.189LOT-R:life orientation test-revisedTable 2Correlation analysis between LOT-R and clinical variables in gout patientsVariablesLOT-RrPAge00.994Disease duration-0.0580.182VAS0.0340.432sUA0.1310.003*Followup sUA0.1260.016*MPR-0.393<0.001*LOT-R: life orientation test-revised,VAS:visual analogue scale,sUA:serum uric acid,MPR:medication possession ratio*P<0.05Conclusion:Gout patients share similar optimistic status to healthy controls.

Abstract
Abstract
Introduction
People with narcolepsy type 1 report that cataplexy is triggered most often by positive social experiences such as laughing with friends, yet the mechanisms through which social interaction promotes cataplexy are unknown. We hypothesize a subpopulation of central amygdala neurons that are sensitive to the prosocial neuropeptide, oxytocin (CeAOTR), respond to positive valence and trigger cataplexy.
Methods
We have used in vivo calcium imaging, chemogenetic and optogenetic approaches to characterize the activity pattern of these neurons and to manipulate their activity state.
Results
Cre-dependent anterograde tracing of the CeAOTR neurons of the central amygdala indicate a moderate to dense projection to the REM sleep-regulatory region of the ventral lateral periaqueductal gray (vlPAG). Additionally, Channel Rhodopsin Assisted Circuit Mapping (CRACM) experiments show that CeAOTR neurons inhibit vlPAG neurons that innervate the REM atonia-promoting region, the sublaterodorsal nucleus. Targeted photostimulation (15Hz (10ms) for 20sec every hour) of the CeAOTR fibers in the vlPAG doubled the amount of cataplexy. Preliminary in vivo calcium imaging indicates that the CeAOTR are active just prior to the onset of cataplexy. Chemogenetic and optogenetic activation of CeAOTR neurons increased cataplexy.
Conclusion
We conclude that the CeAOTR subpopulation is sufficient to promote cataplexy. Our future directions include determining the necessity of these oxytocin sensitive neurons in cataplexy under different conditions of positive valence.

Abstract
We designed and built a diagnostic based on a cathodoluminescent screen for the detection of turbulent plasma structures with high spatial resolution. The screen is coated with a low threshold energy cathodoluminescent powder that emits light when exposed to a plasma. The emitted light is imaged with a fast frame camera combined with an image intensifier and an optical bandpass filter. The diagnostic is used to study turbulent structures and seeded blobs. The results are analyzed with pattern recognition algorithms to track the turbulent structures and study their evolution in time.

Abstract
Magnetic skyrmions are promising candidates for future storage devices with a large data density. A great variety of materials have been found that host skyrmions up to the room-temperature regime. Lorentz microscopy, usually performed in a transmission electron microscope (TEM), is one of the most important tools for characterizing skyrmion samples in real space. Using numerical calculations, this work relates the phase contrast in a TEM to the actual magnetization profile of an isolated Néel or Bloch skyrmion, the two most common skyrmion types. Within the framework of the used skyrmion model, the results are independent of skyrmion size and wall width and scale with sample thickness for purely magnetic specimens. Simple rules are provided to extract the actual skyrmion configuration of pure Bloch or Néel skyrmions without the need of simulations. Furthermore, first differential phase contrast (DPC) measurements on Néel skyrmions that meet experimental expectations are presented and showcase the described principles. The work is relevant for material sciences where it enables the engineering of skyrmion profiles via convenient characterization.

Abstract
Objective: To investigate the effects of ticagrelor on cardiorespiratory fitness in patients with coronary heart disease after percutaneous coronary intervention (PCI). Methods: A total of 1 073 patients, who were diagnosed as coronary heart disease and underwent cardiopulmonary exercise testing (CPET) within 1 year after PCI, were enrolled from September 2017 to September 2019 in Peking University Third Hospital, including 309 patients in ticagrelor group and 764 patients in clopidogrel group. Clinical information, blood test results, echocardiographic parameters, cardiorespiratory fitness related parameters (including peak oxygen uptake (VO(2)), anaerobic threshold VO(2), peak oxygen pulse (VO(2)/HR) and carbon dioxide ventilation equivalent (VE/VCO(2)) slope), coronary lesions and intervention information were obtained. Cardiopulmonary fitness related indexes were compared between the two groups, and the correlation between ticagrelor use and cardiopulmonary fitness related indexes was analyzed by multivariate logistic regression. Patients who underwent CPET within 1 month after PCI were included in the subgroup analysis. Results: In ticagrelor group, the age was (60.3±10.3) years, and 253(81.9%) cases were male. The age of clopidogrel group was (60.6±10.0) years, and there were 608(79.6%) males. No significant differences were observed in peak VO(2), anaerobic threshold VO(2), and peak VO(2)/HR between the two groups (all P>0.05), but the VE/VCO(2) slope was significantly higher in the ticagrelor group than in the clopidogrel group (30.075 (27.207, 33.603) vs. 28.853 (25.970, 32.336), P<0.001). Logistic regression analysis suggested that the peak VO(2), anaerobic threshold VO(2) and peak VO(2)/HR were not significantly correlated with the ticagrelor use (all P>0.05), while the VE/VCO(2) slope was independently correlated with ticagrelor use (OR=1.098, 95%CI 1.032-1.168, P=0.003). Subgroup analysis of patients who underwent CPET within 1 month after PCI also indicated that no significant difference were observed in peak VO(2), anaerobic threshold VO(2), peak VO(2)/HR and VE/VCO(2) slope between the two groups (all P>0.05). Logistic regression analysis suggested that the peak VO(2), anaerobic threshold VO(2) and peak VO(2)/HR were not significantly correlated with ticagrelor use (all P>0.05), while the VE/VCO(2) slope was significantly correlated with ticagrelor use (OR=1.132, 95%CI 1.030-1.244, P=0.010). Conclusion: Among coronary heart disease patients after PCI, treatment with clopidogrel does not result in significant decrease in exercise endurance as compared with patients treated with ticagrelor.

Abstract
Direct-acting antiviral agents (DAAs) are the main antiviral therapeutics for hepatitis C virus-related decompensated stage cirrhosis. DAAs of NS3/4A protease inhibitors use is not recommended for patients with decompensated cirrhosis due to characteristics of DAAs metabolism in liver. The recent guidelines have recommended sofosbuvir (SOF)-based plan including pan-genotype plan of sofosbuvir(SOF)/velpatasvir (VEL), sofosbuvir combined with daclatasvir (DCV), genotype 1,4,5,6 specific plan of sofosbuvir (SOF) / ledipasvir (LDV) for 24 weeks or above in combination with ribavirin for 12 weeks because NS5B and NS5A inhibitors has no obvious effect on CYP450 enzyme system and achievement of sustained virological response (SVR) rates at 12/24 weeks is achievable in 88% ~ 100%, and liver reserve function improves in 42% ~ 53% of patients. Furthermore, approximately 15.5% ~ 49% of patients waiting for liver transplantation after treatment with DAAs do not require liver transplantation for short-term and 10.3% ~19.2% of patients receiving SOF/LDV, and SOF combined with DCV not needed liver transplantation. Thus, the clinical application of DAAs provides a safe and reliable antiviral treatment plan for hepatitis C virus-related decompensated stage cirrhosis.

Abstract
OBJECTIVES To investigate the association between sensory impairment and all-cause mortality among the oldest-old (aged 80 and older) in China. DESIGN Prospective cohort study. SETTING Community-based setting in 22 provinces of China. PARTICIPANTS A total of 8788 older adults aged 80 and over at baseline with complete hearing and vision function data were included as the study population. MEASUREMENTS Sensory impairment was categorized as no sensory impairment, hearing impairment (HI) only, vision impairment (VI) only and dual sensory impairment (DSI) according to hearing and vision function. Deaths were identified through interviews by close family members. Cox proportion hazards regression models were used to examine the association of sensory impairment with mortality, adjusting for socio-demographic data, life style factors and health status. RESULTS The mean age was 92.3 ± 7.6 years old, and 60.1% of participants were female. Among 8788 participants, 9.8% were recognized as DSI, 9.7% were HI only and 10.4% with VI only. Comparing with participants with no sensory impairment, those with VI only (HR=1.10, 95% CI=1.01-1.20) and DSI (HR=1.21, 95% CI=1.09-1.35) were significantly associated with higher risk of all-cause mortality in the fully adjusted model. CONCLUSION Our results demonstrated that VI only and DSI were significantly associated with higher risk of mortality among Chinese older adults aged 80 and over. The finding advocated that it is necessary to identify and manage sensory impairments for the advanced ages to reduce mortality risks.

Abstract
OBJECTIVES To estimate the prevalence of sarcopenia in different ethnic groups and the association with cultural life styles in west China. DESIGN A cross-sectional study. SETTINGS The communities in Yunnan, Guizhou, Sichuan, and Xinjiang provinces. PARTICIPANTS 4500 participants aged 50 years or older in west China were enrolled in this study. Sarcopenia was defined according to the diagnostic algorithm of the Asia Working Group for Sarcopenia (AWGS). MEASUREMENTS We measured gait speed, handgrip strength and muscle mass by using bioelectrical impedance analysis (BIA) for all eligible participants. Life-style information were collected by reviewers. Relationships between sarcopenia and ethnic groups were analyzed using univariate and multivariate analyses. RESULTS We found 869 (19.31%) adults aged 50 years old or older were sarcopenia. The mean age is 62.4±8.3 years. The main ethnic groups enrolled in this study is Han, Tibetan, Qiang, Yi and Hui. The crude prevalence of sarcopenia is 22.3% in Han, 18.2% in Tibetan, 11.8% in Qiang, 34.7% in Yi and 26.7% in Hui. Compared to Han, after adjusting sex and age, Qiang has a lower prevalence of sarcopenia (odds ratio [OR]: 0.44, 95% CI 0.35-0.55), Yi has a higher prevalence of sarcopenia (OR: 1.78, 95% CI 1.29-2.43). While adding adjusting other potential cofounders, sarcopenia is still less prevalent in Qiang (OR: 0.44, 95% CI 0.34-0.57). CONCLUSIONS The crude prevalence of sarcopenia is 22.3% in Han, 18.2% in Tibetan, 11.8% in Qiang, 34.7% in Yi and 26.7% in Hui. Sarcopenia was less prevalent in Qiang compared with Han. Further studies to determine related factors of sarcopenia among different ethnic groups are recommended.

Abstract
OBJECTIVE Frailty and poor oral health are both common age-related conditions. However, the association between oral health and frailty has not been explored thoroughly among older Chinese adults. We aimed to investigate the associations between number of teeth, denture use, and frailty among older adults in western China. DESIGN Cross-sectional study. SETTING Community-based. PARTICIPANTS Participants were 4037 community-dwelling individuals aged 60 and older from the West China Health and Aging Trend (WCHAT) study. MEASUREMENTS Frailty was assessed using the physical frailty phenotype (PFP) and categorized as non-frail, prefrail and frail. In addition, number of teeth and denture use were examined by calibrated dentists. Multinomial logistic regression models were performed to examine the association between number of teeth, denture use, and frailty. RESULTS The overall prevalence of frailty was 6.7% among 4037 participants aged 60 and older in western China. Participants with no more than 20 teeth were associated with higher odds of being prefrail or frail whether wearing dentures or not. Denture using could not help lower the odds of being prefrail or frail for older adults with fewer teeth. CONCLUSIONS This study suggested that frailty was associated with having fewer teeth (≤20 teeth) among older Chinese adults. Future research involving targeted interventions addressing number of teeth may help provide information to establish effective strategies for frailty prevention in older adults.

Abstract
OBJECTIVE To identify the prevalence, lifestyle factors, chronic disease status, and assessing the metabolic profile, comparing key differences in a cohort of subjects with non-sarcopenia/non-obesity (H), sarcopenia/non-obesity (S), non-sarcopenia/obesity (O) and sarcopenia obesity (SO) in a multi-ethnic population in west China. DESIGN A cross-sectional study. SETTING The communities in Yunnan, Guizhou, Sichuan, and Xinjiang provinces. PARTICIPANTS We included 4,500 participants aged 50 years or older who did bioelectrical impedance in our analysis from West China Health and Aging Trend (WCHAT) study. MEASUREMENTS We measured gait speed, handgrip strength and muscle mass by using bioelectrical impedance analysis (BIA) for all participants. We defined sarcopenia using the diagnostic algorithm recommended by the Asian Working Group for Sarcopenia (AWGS). Obesity was defined as the highest sex-specific quintile of the percentage body fat. Different variables like anthropometry measures, life styles, chronic disease and blood test were collected. Analysis of variance and a multinomial logistic regression analysis adjusting for covariates were used to assess the differences of metabolic profiles among different groups. RESULTS Of 4500 participants aged 50 years old or older, the proportions of H, O, S, SO were 63.0%, 17.7%, 16.7% and 2.6%, respectively. And the prevalence of S subjects in men was 18.3% and 15.7% in women, while the prevalence of SO was 3.7% in men and 2.0% in women. Data showed that the prevalence of S and SO has an aging increase pattern which was opposite with O. Both S and SO tends to be older, lower educational level, without spouse, smoking, comorbidity of chronic disease, poor nutrition status, depression and cognitive decline compared to H and S seems to be worse than SO. Compared to H, S cohort showed a decrease in Vitamin D, triglyceride, albumin, fasting glucose, insulin, creatinine, ALT, nutrition scores and increase in HDL. SO cohort were observed for an increase in cholesterol, LDL, total protein and decrease in vitamin D. While O cohort showed an increase in triglyceride, cholesterol, LDL, total protein, glucose, insulin, WBC, uric acid, ALT and nutrition scores, but a decrease in HDL and vitamin D level. CONCLUSIONS Among individuals aged 50 years old or older in West China. S, O and SO participants demonstrate distinct differences in the life-styles, chronic disease profile, and metabolic profiles. The prevalence of S and SO has an aging increase pattern contrary to O. Both S and SO tend to be older, lower educational level, without spouse, smoking, comorbidity of chronic disease, poor nutrition status, depression and cognitive decline compared to H and S looks like to be worse than SO. Besides, the S subjects seem to have more metabolic index changes than SO compared to H. While O subjects have some contrary metabolic index to S subjects.

Abstract
OBJECTIVES Previous literature has reported that physical frailty (PF) closely associated with cognitive impairment (CI). In this study, we aim to describe and evaluate the prevalence and associated factors with different patterns of PF and cognitive impairment. DESIGN A cross-sectional study. SETTING AND PARTICIPANTS Community-dwelling older adults aged ≥60 from the West China Health and Aging Trend (WCHAT) study were included in this study. MEASUREMENTS Participants were assessed the PF and cognitive impairment. PF was assessed using the physical phenotype as defined by Fried's criteria. Cognitive impairment was identified using the Short Portable Mental Status Questionnaire (SPMSQ). According different patterns of PF and cognitive impairment, participants were divided into 4 groups: not-PF and cognitive intact ( "neither" group), not-PF and cognitive impairment ("CI only" group), PF and cognitive intact ("PF only" group), and PF and cognitive impairment ("both" group). Multinomial logistic regression was used to explore the association between medical conditions and different patterns of PF and cognitive impairment after adjusting the demographic characteristics. RESULTS Among 4,103 participants (age 67.8 + 5.9 years, female 58.3%), 78.8%, 3.9%, 14.5% and 2.9% were "neither", "PF only", "CI only", and "both", respectively. The prevalence of "PF only", "CI only" and "both" were associated with age, lower education level and single status. In addition, there was substantial ethnicity heterogeneity in the prevalence of different patterns of PF and cognitive impairment. Comparing with "neither", PF and/or cognitive impairment had higher association with depression, ADLs impairment, and malnutrition. Of note, obesity was only significantly associated with "PF only", but not associated with "CI only" or "both". CONCLUSIONS We found the substantial demographic and medical conditions disparities in different patterns of PF and cognitive impairment. Further research should focus on the efficient and practical screen to predict the risk of "PF only", "CI only" and "both".

Abstract
Currents play critical roles in neurons. Direct observation of current flows in cells at nanometre dimensions and picoampere current resolution is still a daunting task. In this study, we investigated the current flows in hippocampal neurons, PC12 cells and astrocytes in response to voltages applied to the cell membranes using conductive atomic force microscopy (CAFM). The spines in the hippocampal neurons play crucial roles in nerve signal transfer. When the applied voltage was greater than 7.2 V, PC12 cells even show metallic nanowire-like characteristics. Both the cell body and glial filaments of astrocytes yielded CAFM test results that reflect different electrical conductance. To our best knowledge, the electrical characteristics and current transport through components of cells (especially neurons) in response to an applied external voltage have been revealed for the first time at nanometre dimensions and picoampere current levels. We believe that such studies will pave new ways to study and model the electrical characteristics and physiological behaviours in cells and other biological samples.

Abstract
Immune tolerance is one of the leading causes of chemotherapy resistance in carcinoma cases. Studies have shown that programmed cell death ligand-1 (PD-L1), an inhibitory molecule expressed by cancer cells, plays a significant role in immune tolerance through the induction of T cell dysfunction. The results of our RNA sequencing in previous studies revealed that microRNA-145 (miR-145), which is known to be down-regulated by cisplatin in cisplatin-resistant ovarian cancer cells, also represses gene PD-L1 expression. However, the mechanism by which miR-145 contributes to regulate PD-L1 expression in cisplatin resistance of ovarian cancer is yet to be fully understood. Here, we show that cisplatin-mediated miR-145 down-regulation increased PD-L1 expression via targeting the c-Myc transcription factor, thereby inducing T cell apoptosis in vitro. We also report that expression of miR-145 is negatively correlated with PD-L1 expression in human ovarian cancer tissues, malignant grades and the recurrent risks of ovarian cancer after chemotherapy. In summary, our findings suggest that the miR-145/c-Myc/PD-L1 axis contributes to cisplatin resistance in ovarian cancer and support that miR-145 might act as an adjuvant therapeutic target in chemotherapy of ovarian cancer.

Abstract
Objective: To analyze the clinical characteristics of newly treated high-risk group neuroblastoma (NB) patients with bone marrow metastasis and to explore the prognostic factors. Methods: The clinical features (sex, age, stage, risk group, pathological type, metastatic site, etc.) of 203 newly treated high-risk NB patients with bone marrow metastasis admitted to Hematology Oncology Center, Beijing Children's Hospital from January 2007 to December 2016 were analyzed retrospectively. There were 118 males (58.1%) and 85 females (41.9%). Kaplan-Meier method was used for survival analysis and Cox regression was used to analyze the prognostic factors. Results: The age at onset of the 203 patients was 41 months (9-147 months). The metastatic sites at diagnosis were as follows: bone in 195 cases (96.1%), distant lymph nodes in 104 cases (51.2%), skull and endomeninx in 61 cases (30.0%), orbit in 30 cases (14.8%), pleura in 16 cases (7.9%), liver in 13 cases(6.4%), canalis spinalis in 13 cases (6.4%), other sites in 11 cases (5.4%) and skin and soft tissue in 10 cases (4.9%). In all, 194 cases were enrolled for prognostic analysis. The follow-up time was 36 months (1 day-138 months) , and the 5-years event free survival (EFS) and overall survival (OS) were 36.1% and 39.7%, respectively. A total of 118 patients (60.8%) had events (first relapse or death) with the time to event occurrence was 15 months (1 day-72 months), whereas 112 patients (57.7%) died with the event occurrence to death time was 3 months (1 day-21 months). There was no significant difference in 5-years OS between radiotherapy group and non-radiotherapy group (42.3% vs. 38.3%, χ(2)=3.671, P=0.055). The 5-years OS in transplantation group was significantly better than the non-transplantation group (44.3% vs. 35.5%, χ(2)=8.878, P=0.003), and the radiotherapy combined transplantation group also had a better 5-years OS rate than the non-radiotherapy combined transplantation group (45.8% vs. 37.3%, χ(2)=5.945, P=0.015). Univariate survival analysis showed lactate dehydrogenase ≥ 1 500 U/L, the amplification of MYCN, the metastatic sites of orbit, canalis spinalis and pleura were associated with poor prognosis of newly diagnosed high-risk NB patients (χ(2)=21.064, 13.601, 3.998, 6.183, 15.307, all P<0.05). The amplification of MYCN and the metastatic sites of pleura were risk factors for prognosis of newly diagnosed high-risk NB patients by Cox regression models (HR=1.896,1.100, 95%CI: 1.113-3.231, 1.020-1.187, both P<0.05). Conclusions: The prognosis is unfavorable in high-risk group NB patients with BM metastasis. Radiotherapy combined with transplantation can further improve the prognosis of these patients. The amplification of MYCN and the metastatic sites of pleura were the poor prognostic factors for high-risk NB patients with bone marrow metastasis.

Abstract
Objective: To explore the expression levels of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) protein and the change of MMP-9/TIMP-1 ratio in wound exudates of patients with stages Ⅲ and Ⅳ pressure ulcers during wound healing. Methods: From July 2017 to July 2018, 30 patients with stage Ⅲ pressure ulcers [30 wounds, 16 males and 14 females, aged (65±10) years] and 34 patients with stage Ⅳ pressure ulcers [50 wounds, 17 males and 17 females, aged (65±9) years] admitted to Hebei General Hospital who met the inclusion criteria were enrolled in this prospective cohort study. According to the principle of wound treatment and the characteristics and needs of wound in different periods, individualized intervention measures were formulated for patients and appropriate dressings were selected. At the time of admission and on 7, 14, 21, 28 days of treatment, the healing of pressure ulcer wounds was evaluated by Pressure Ulcer Healing Scale. Afterwards, the wound exudate was collected at each time point to detect the expression levels of MMP-9 and TIMP-1 protein by enzyme-linked immunosorbent assay, and the MMP-9/TIMP-1 ratio was calculated. Data were processed with analysis of variance for repeated measurements of single group and linear trend test. Results: (1) There were significantly statistical differences in wound healing scores of patients with stages Ⅲ and Ⅳ pressure ulcers among the time of admission and on 7, 14, 21, 28 days of treatment within each stage (F=145.382, 153.234, P<0.01), and they all showed a gradually decreasing trend (F=170.466, 284.585, P<0.01). (2) At the time of admission and on 7, 14, 21, 28 days of treatment, the expression levels of MMP-9 protein in wound exudates of patients with stages Ⅲ and Ⅳ pressure ulcers were (171±104), (138±88), (110±70), (85±55), (62±41) ng/L and (193±107), (173±104), (139±83), (114±70), (89±56) ng/L, respectively. There were significantly statistical differences within each stage (F=58.007, 111.680, P<0.01), and they all showed a gradually decreasing trend (F=62.901, 134.628, P<0.01). At the time of admission and on 7, 14, 21, 28 days of treatment, the expression levels of TIMP-1 protein in wound exudates of patients with stages Ⅲ and Ⅳ pressure ulcers were (6.2±3.9), (5.6±3.4), (5.1±3.1), (4.4±2.5), (3.8±2.3) ng/L and (4.8±2.5), (4.7±2.6), (4.4±2.6), (4.6±2.7), (4.1±2.4) ng/L, respectively. There were significantly statistical differences within each stage (F=25.479, 7.778, P<0.01), and there was a gradually decreasing trend in stage Ⅲ (F=62.901, P<0.01) and a decreasing trend in stage Ⅳ (F=134.628, P<0.01). At the time of admission, the expression levels of MMP-9 and TIMP-1 in wound exudates of patients with stage Ⅲ pressure ulcers were similar to those of patients with stage Ⅳ pressure ulcers (t=-1.03, 1.47, P>0.05). (3) At the time of admission and on 7, 14, 21, 28 days of treatment, the MMP-9/TIMP-1 ratios in the wound exudates of patients with pressure ulcers of stages Ⅲ and Ⅳ were 30±13, 25±9, 22±9, 20±8, 17±6 and 43±19, 37±13, 32±10, 26±9, 22±9, respectively. There were significantly statistical differences within each stage (F=37.173, 97.191, P<0.01), and they all showed a gradually decreasing trend (F=54.183, 130.088, P<0.01). At the time of admission, the MMP-9/TIMP-1 ratio in wound exudates of patients with stage Ⅳ pressure ulcers was significantly higher than that of patients with stage Ⅲ pressure ulcers (t=-3.42, P<0.01). Conclusions: During the wound healing process of patients with stages Ⅲ and Ⅳ pressure ulcers, the expression levels of MMP-9 and TIMP-1 protein and the MMP-9/TIMP-1 ratio in wound exudates show a decreasing trend. The stage of wound healing can be predicted according to the expression level of MMP-9 protein and the MMP-9/TIMP-1 ratio.

Abstract
Objective: To investigate the anatomy and application of endoscopic transpterygoid intervention in lesions of lateral recess of sphenoid sinus(LRSS). Method: Four hospitalized patients with lesions of LRSS were studied. The clinical presentations included spontaneous cerebrospinal fuild(CSF) leakage in 2 cases, meningoencephaolece complicated CSF leakage in 1 case and chronic invasive fungal sphenoid sinusitis invading the base of the middle fossa in 1 case. Endoscopic transpterygoid intervention and repairment of skull base defects were performed under general anesthesia. Result: he operations were successfu1 in all patients. One patient suffered from postoperative palatal hypesthesia and all the symptoms mentioned above relieved gradually 6 months after operation. No recurrence was found during the follow-up ranging from 6 to 45 months(mean follow-up period,22.75 months).Conclusion: Endoscopic transpterygoid intervention in lesions of LRSS is a minimally invasive and safe surgical approach.

Abstract
OBJECTIVE Accumulating data show that platelet to lymphocyte ratio (PLR) and neutrophil to monocyte ratio (NMR) undergo changes during inflammation in various diseases; however, the clinical features remain unclear in knee osteoarthritis (OA) patients. The purpose of our study was to evaluate PLR and NMR in knee OA patients, and assess their relationship to knee OA's radiographic grades. METHODS A retrospective study on 132 adult knee OA patients and 162 healthy controls (HC) was performed. All clinical characteristics of the knee OA patients were obtained from their medical records. PLR and NMR were compared between knee OA patients and HC by non-parametric tests. Correlations of PLR and NMR with Kellgren-Lawrence (KL) classification (KL grade 2, KL grade 3, and KL grade 4) were also analyzed through a Spearman correlation test. Ordinal polytomous logistic regression was used to determine independent factors influencing radiographic grades of knee OA patients. RESULTS PLR was increased significantly in knee OA patients, while a statistical difference in NMR was not observed. However, PLR was not relevant to KL grades, while NMR was negatively correlated with these (r = -0.330, P < 0.01) and was independently associated with KL grades of knee OA. CONCLUSION PLR could reflect the inflammation response of knee OA. NMR emerged as an independent factor and could be used as a potential marker indicating the severity of knee OA.

Abstract
Body conformation at birth and teat number are economically important traits in the pig industry, as these traits are usually explored to evaluate the growth and reproductive potential of piglets. To detect genetic loci and candidate genes for these traits, we performed a GWAS on 269 pigs from a recently developed Chinese breed (Sushan) using 38 128 informative SNPs on the Affymetrix Porcine SNP 55K Array. In total, we detected one genome-wide significant (P = 1.31e-6) SNP for teat number on chromosome X and 15 chromosome-wide significant SNPs for teat number, body weight, body length, chest circumference and cannon circumference at birth on chromosomes 1, 3, 4, 6, 7, 9, 10, 13, 14, 15, 17 and 18. The most significant SNP had an additive effect of 0.74 × total teat number, explaining 20% of phenotypic variance. Five significant SNPs resided in the previously reported quantitative trait loci for these traits and seven significant SNPs had a pleiotropic effect on multiple traits. Intriguingly, 12 of the genes nearest to the significant SNPs are functionally related to body conformation and teat number traits, including SPRED2, MKX, TMSB4X and ESR1. GO analysis revealed that candidate genes proximal to the significant SNPs were enriched in the G-protein coupled receptor and steroid hormone-mediated signaling pathway. Our findings shed light on the genetic basis of the measured traits and provide molecular markers especially for the genetic improvement of teat number in Sushan and related pigs.
