Abstract
The progressive degradation in the trabecular meshwork (TM) is related to age-related ocular diseases like primary open-angle glaucoma. However, the molecular basis and biological significance of the aging process in TM have not been fully elucidated. Here, we established a dynamic single-cell transcriptomic landscape of aged macaque TM, wherein we classified the outflow tissue into 12 cell subtypes and identified mitochondrial dysfunction as a prominent feature of TM aging. Furthermore, we divided TM cells into 13 clusters and performed an in- depth analysis on cluster 0, which had the highest aging score and the most significant changes in cell proportions between the two groups. Ultimately, we found that the APOE gene was an important differentially expressed gene in cluster 0 during the aging process, highlighting the close relationship between cell migration and extracellular matrix regulation, and TM function. Our work further demonstrated that silencing the APOE gene could increase migration and reduce apoptosis by releasing the inhibition on the PI3K-AKT pathway and downregulating the expression of extracellular matrix components, thereby increasing the aqueous outflow rate and maintaining intraocular pressure within the normal range. Our work provides valuable insights for future clinical diagnosis and treatment of glaucoma.

Abstract
AIM To explore the value of preoperative computed tomography (CT) histogram features in predicting the expression status of Ki-67 in patients with solid pseudopapillary pancreatic tumours (SPTP). MATERIALS AND METHODS This retrospective study analysed venous phase CT images of 39 patients with SPTP confirmed at surgery and histopathology and measured using the Ki-67 proliferation index from November 2015 to February 2022. According to the Ki-67 proliferation index, they were divided into high expression (Ki-67 ≥ 4%) and low expression (Ki-67 < 4%) groups. The histogram features of quantitative parameters were extracted using MaZda software, and the quantitative parameters of CT histograms were compared between groups. The receiver operating characteristic (ROC) curves of the patients were plotted according to the parameters, with statistically significant differences. The area under the curve (AUC), sensitivity, and specificity were calculated, and the effectiveness of the histogram parameters in predicting Ki-67 expression was analysed and evaluated. RESULTS In total, 27 SPTP patients were enrolled, including 11 with high expression of Ki-67 and 16 with low expression. Comparative analysis of the Ki-67 high- and low-expression groups revealed a statistically significant in necrosis and variance (p<0.05). ROC curve analysis showed that the AUC of necrosis and variance predicting Ki-67 expression status were 0.753 and 0.841, the sensitivities were 81.8% and 81.3%, and the specificities were 68.7% and 81.8%, respectively. CONCLUSION Preoperative CT histogram features help predict Ki-67 expression status in patients with SPTP.

Abstract
Glaucoma is a highly heritable disease, and myocilin was the first identified causal and most common pathogenic gene in glaucoma. Serine-to-proline mutation at position 341 of myocilin (MYOCS341P) is associated with severe glaucoma phenotypes in a five-generation primary open-angle glaucoma family. However, the underlying mechanisms are underexplored. Herein, we established the MYOCS341P transgenic mouse model and characterized the glaucoma phenotypes. Further, we systematically explored the functional differences between wild-type and MYOCS341P through immunoprecipitation, mass spectrometry, and RNA-seq analyses. We found that MYOCS341P transgenic mice exhibit glaucoma phenotypes, characterized by reduced aqueous humor outflow, elevated intraocular pressure, decreased trabecular meshwork (TM) cell number, narrowed Schlemm's canal, retinal ganglion cell loss, and visual impairment. Mechanistically, the secretion of dysfunctional MYOCS341P accumulated in the endoplasmic reticulum (ER), inducing ER stress and dysregulation of autophagy, thereby promoting TM cell death. We describe an effective transgenic model for mechanistic studies and the screening of therapeutic targets. Our data generated from high-throughput analyses help elucidate the mechanism underlying mutant MYOC-related glaucoma.

Abstract
AIM To investigate the value of pre-chemotherapy spectral computed tomography (CT) parameters in predicting neoadjuvant chemotherapy (NAC) response in gastric cancer (GC). MATERIALS AND METHODS Sixty patients with GC who received NAC and underwent spectral CT examination before chemotherapy were enrolled retrospectively and divided into a responsive group and a non-responsive group according to the postoperative pathological tumour regression grade. Clinical characteristics were collected. The iodine concentration (IC), water concentration (WC), and effective atomic number (Eff-Z) of the portal venous phases were measured before chemotherapy, and IC was normalised to that of the aorta to provide the normalised IC (NIC). An independent samples t-test, Mann-Whitney U-test, or chi-square test was used to analyse the differences between the two groups, and the receiver operating curve (ROC) was used to evaluate the predictive performance of different variables. RESULTS The neutrophil-to-lymphocyte ratio (NLR) was lower in the responsive group than in the non-responsive group (p<0.05). IC, NIC, and Eff-Z values were significantly higher in the responsive group than in the non-responsive group (p<0.01). The areas under the ROC curves for the NLR, IC, NIC, and Eff-Z were 0.694, 0.688, 0.799, and 0.690, respectively. The combination of NIC, Eff-Z, and NLR values showed good diagnostic performance in predicting response to NAC in GC, with an area under the ROC curve of 0.857, 76.92% sensitivity, 80% accuracy, and 85.71% specificity. CONCLUSION Spectral CT parameters may serve as non-invasive tools for predicting the response to NAC in patients with GC.

Abstract
BACKGROUND From November 2022 to February 2023, the Chinese mainland experienced a surge in COVID-19 infection and hospitalization, and the hospital-based healthcare workers (HCWs) might suffer serious psychological crisis during this period. This study aims to assess the depressive and anxiety symptoms among HCWs during the surge of COVID-19 pandemic and to provide possible reference on protecting mental health of HCWs in future infectious disease outbreaks. METHODS A multicenter cross-sectional study was carried out among hospital-based HCWs in the Chinese mainland from 5 January to 9 February 2023. The PHQ-9 (nine-item Patient Health Questionnaire) and GAD-7 (seven-item Generalized Anxiety Disorder Questionnaire) were used to measure depressive and anxiety symptoms. Ordinal logistic regression analysis was performed to identify influencing factors. RESULTS A total of 6522 hospital-based HCWs in the Chinse mainland were included in this survey. The prevalence of depressive symptoms among the HCWs was 70.75%, and anxiety symptoms was 47.87%. The HCWs who perceived higher risk of COVID-19 infection and those who had higher work intensity were more likely to experience depressive and anxiety symptoms. Additionally, higher levels of mindfulness, resilience and perceived social support were negatively associated with depressive and anxiety symptoms. CONCLUSION This study revealed that a high proportion of HCWs in the Chinese mainland suffered from mental health disturbances during the surge of the COVID-19 pandemic. Resilience, mindfulness and perceived social support are important protective factors of HCWs' mental health. Tailored interventions, such as mindfulness practice, should be implemented to alleviate psychological symptoms of HCWs during the COVID-19 pandemic or other similar events in the future.

Abstract
The pathogenesis of glaucoma is still unknown. There are few studies on the dynamic change of tissue-specific and time-specific molecular pathophysiology caused by ocular hypertension (OHT). This study aimed to identify the early proteomic alterations in the retina, optic nerve head (ONH), and optic nerve (ON). After establishing a rat model of OHT, we harvested the tissues from control and glaucomatous eyes and analyzed the changes in protein expression using a multiplexed quantitative proteomics approach (TMT-MS3). Our study identified 6403 proteins after 1-day OHT and 4399 proteins after 7-days OHT in the retina, 5493 proteins after 1-day OHT and 4544 proteins after 7-days OHT in ONH, and 5455 proteins after 1-day OHT and 3835 proteins after 7-days OHT in the ON. Of these, 560 and 489 differential proteins were identified on day 1 and 7 after OHT in the retina, 428 and 761 differential proteins were identified on day 1 and 7 after OHT in the ONH, and 257 and 205 differential proteins on days 1 and 7 after OHT in the ON. Computational analysis on day 1 and 7 of OHT revealed that alpha-2 macroglobulin was upregulated across two time points and three tissues stably. The differentially expressed proteins between day 1 and 7 after OHT in the retina, ONH, and ON were associated with glutathione metabolism, mitochondrial dysfunction/oxidative phosphorylation, oxidative stress, microtubule, and crystallin. And the most significant change in retina are crystallins. We validated this proteomic result with the Western blot of crystallin proteins and found that upregulated on day 1 but recovered on day 7 after OHT, which are promising as therapeutic targets. These findings provide insights into the time- and region-order mechanisms that are specifically affected in the retina, ONH, and ON in response to elevated IOP during the early stages.

Abstract
Low intracranial pressure (LICP)-induced translaminar cribrosa pressure difference (TLCPD) elevation has been proven as a risk factor in glaucomatous neurodegeneration, whereas the underlying retinal immune features of LICP-induced retinal ganglion cells (RGC) injury remain elusive. Here, we identified the retinal immune characteristics of LICP rats, and minocycline (Mino) treatment was utilized to analyze its inhibitory role in glia-mediated retinal inflammation of LICP rats. The results showed that retrograde axonal transport was decreased in LICP rats without significant RGC loss, indicating the RGC injury was at an early stage before the morphological loss. The activation of retinal microglia and astrocytes with morphologic and M1 or A1-marker alternations was detected in TLCPD elevation rats, the activation level is more dramatic in HIOP rats than in the LICP rats (P<0.05). Besides, we detected reduced retinal tight junction protein expressions, accompanied by specific imbalance patterns of T lymphocytes in the retina of both LICP and HIOP rats (P<0.05). Further Mino treatment showed an effective inhibitory role in glia-driven inflammatory responses in LICP rats, including improving retrograde axonal transport, inhibiting retinal glial activation and proinflammatory subtype polarization, and alleviating the blood-retina barrier compromise. This study identified the glia-mediated retinal inflammation features triggered by LICP stimulus, and Mino application exhibited an effective role in the inhibition of retinal glia-mediated inflammation in LICP-induced TLCPD elevation rats.

Abstract
OBJECTIVES To provide reference values of trans-laminar cribrosa pressure difference (TLCPD) and reveal the association of TLCPD with systemic biometric factors. METHODS In this cross-sectional study, 526 quasi-healthy subjects (including 776 eyes) who required lumbar puncture for medical reasons were selected from 4915 neurology inpatients from 2019 to 2022. Patients with any diseases affecting intraocular pressure (IOP) or intracranial pressure (ICP) were excluded. The ICPs of all subjects were obtained by lumbar puncture in the left lateral decubitus position. IOP was measured in the seated position by a handheld iCare tonometer prior to lumbar puncture. TLCPD was calculated by subtracting ICP from IOP. Systemic biometric factors were assessed within 1 h prior to TLCPD measurement. RESULTS The TLCPD (mean ± standard deviation) was 4.4 ± 3.6 mmHg, and the 95% reference interval (defined as the 2.5th-97.5th percentiles) of TLCPD was -2.27 to 11.94 mmHg. The 95% reference intervals for IOP and ICP were 10-21 and 6.25-15.44 mmHg, respectively. IOP was correlated with ICP (r = 0.126, p < 0.001). TLCPD was significantly negatively correlated with body mass index (r = -0.086, p = 0.049), whereas it was not associated with age, gender, height, weight, blood pressure, pulse, or waist and hip circumference. CONCLUSIONS This study provides reference values of TLCPD and establishes clinically applicable reference intervals for normal TLCPD. Based on association analysis, TLCPD is higher in people with lower BMI.

Abstract
Diabetes mellitus-induced hyperglycemia is responsible for multiple pathological ocular alternations from vasculopathy to biomechanical dyshomeostasis. Biomechanical homeostasis is crucial to maintain the normal physiological condition of the eyes. Biomechanical features vary in eye tissues regarding different anatomical positions, tissue components, and cellular functions. The disturbance in biomechanical homeostasis may result in different ocular diseases. In this review, we provide a preliminary sketch of the latest evidence on the mechano-environment of the eyeball and its possible influencing factors, thereby underscoring the relationship between the dyshomeostasis of ocular biomechanics and common eye diseases (e.g., diabetic retinopathy, keratoconus, glaucoma, spaceflight-associated neuro-ocular syndrome, retinal vein occlusion and myopia, etc.). Together with the reported evidence, we further discuss and postulate the potential role of biomechanical homeostasis in ophthalmic pathology. Some latest strategies to investigate the biomechanical properties in ocular diseases help unveil the pathological changes at multiple scales, offering references for making new diagnostic and treatment strategies targeting mechanobiology.

Abstract
Objective: To investigate the impact of lung metastases on the prognosis of patients with gestational trophoblastic neoplasia (GTN). Methods: Patients with International Federation of Gynaecology and Obstetrics (FIGO) stage Ⅰ-Ⅲ GTN receiving primary chemotherapy in Peking Union Medical College Hospital between July 2014 and December 2018 were retrospectively analyzed and divided into group 1 with lung metastasis and group 2 without lung metastasis. The baseline characteristics and treatment outcomes of the two groups were compared. The optimal cut-off values of the diameter of largest lung nodule associated with recurrence were identified by receiver operating characteristic (ROC) curves. Logistic regression analyses were performed to identify risk factors for prognosis. Survival analysis was performed by Kaplan-Meier method and Log rank test. Results: Of the 381 GTN patients enrolled (216 with lung metastases and 165 without lung metastases), the pretreatment β human chorionic gonadotrophin [median: 12 572 IU/L (1 832-51 594 IU/L) vs. 5 614 IU/L (559-26 140 IU/L), P=0.001] and FIGO score [median: 3 (1-6) vs. 2 (1-4), P=0.038] were significantly higher in patients with lung metastases than those without lung metastases. In patients with FIGO score≥5, the emergence of resistance (26.76% vs. 10.26%, P=0.036) and median number of chemotherapy courses to achieve complete remission [6 (6-8) vs. 5 (4-6), P<0.001] were significantly higher than patients with lung metastases. In patients with FIGO score 0-4, no significant difference was found in the treatment outcomes between the two groups(P=0.833). Among all patients with lung metastases, the ROC curve showed a sensitivity and specificity of 62.5% and 78.8%, respectively, for predicting recurrence when the length of the largest lung nodule was 1.6 cm, with an area under the curve (AUC) of 0.711 (95% CI: 0.550, 0.871, P=0.044). Multivariate logistic regression analysis suggested a significantly higher recurrence rate when the largest lung nodule was ≥1.6 cm (OR=7.394, 95% CI: 1.003, 54.520, P=0.049). The 1-year disease-free survival rate was significantly lower in patients with the largest lung nodule ≥1.6 cm than in patients with the nodule <1.6 cm (98.2% vs. 82.4%, P=0.001). Conclusions: Lung metastasis is associated with increased first-line chemotherapy resistance in patients with FIGO scores≥5. The diameter of the largest lung metastatic nodule ≥1.6 cm is an effective factor for predicting recurrence.

Abstract
Objective: To evaluate the oncologic outcomes of different laparoscopic radical hysterectomy. Methods: From January 2011 to December 2014, the laparoscopic operation cases of cervical cancer at stage Ⅰb1, Ⅰb2, Ⅱa1 and Ⅱa2, including the histologic subtypes of squamous-cell carcinoma, adenocarcinoma and adenosquamous carcinoma, were collected in five clinical centers. The data were divided into two groups according to the surgical procedures, that is, modified laparoscopic-vaginal radical hysterectomy (mLVRH) and total laparoscopic radical hysterectomy (TLRH). The overall survival rate (OS), disease-free survival rate (DFS) at 5 years were retrospectively analyzed in this study. Results: There were 674 cases in total, including 377 cases of mLVRH, 297 cases of TLRH. (1) The OS at 5 years: the mLVRH was 96.1% and the TLRH was 92.0%, and the mLVRH was higher than that of TLRH (P=0.010). Stratify analysis, including stage of disease (Ⅰb1 and Ⅱa1), histologic subtypes (squamous-cell carcinoma, adenocarcinoma), lymph node metastasis, revealed that, ① Stage of disease: in stage Ⅰb1, the OS at five years of mLVRH was higher than that in TLRH group (98.6% vs 93.6%, P=0.012). In stage Ⅱa1, there was significant difference between the two groups, the OS at five years of mLVRH and TLRH were 93.6% and 77.6% (P=0.007). ② Histologic subtypes: for the OS at five years of squamous-cell carcinoma, mLVRH and TLRH were 96.1% and 92.3%, and there was significant difference (P=0.046); for adenocarcinoma, the OS at five years were 91.0% and 88.6%, and there was no difference between two groups (P=0.230). ③ Lymph node metastasis: the mLVRH and TLRH with lymph node metastasis, the OS at five years were 98.6% and 96.4%; the mLVRH and TLRH without lymph node metastasis, the OS at five years were 89.3% and 80.8%. There were no significant differences between the two groups,respectively (P=0.156, P=0.093). (2) The DFS at 5 years: there was no significant difference between mLVRH and TLRH (94.1% vs 90.9%, P=0.220). Stratify analysis for stage of disease, the mLVRH group was higher than that in the TLRH group in stage Ⅰb1 (97.0% vs 92.8%, P=0.039). However, for stage Ⅱa1, there was no significant difference between mLVRH and TLRH group (88.2% vs 75.8%, P=0.074). Conclusions: The results of this retrospective study indicated that different laparoscopy surgical procedures had diverse oncologic outcomes. The OS at 5 years of the mLVRH is superior to the TLRH. The DFS at 5 years in Ⅰb1 stage, the mLVRH is higher than the TLRH. Therefore, the modified laparoscopy is still an alternative surgery for early cervical cancer patients when following the principle of no-tumor-exposure.

Abstract
Objective: To evaluate the clinical characteristics and prognosis of gallbladder cancer (GBC) patients in China. Methods: This retrospective multicenter cohort study enrolled 3 528 consecutive GBC patients diagnosed between January 2010 to December 2017 in 15 hospitals from 10 provinces. There were 1 345 (38.12%) males and 2 183 (61.88%) females.The age of diagnosis was (63.7±10.8) years old (range: 26 to 99 years old) .There were 213 patients (6.04%) in stage 0 to Ⅰ, whereas 1 059 (30.02%) in stage Ⅱ to Ⅲ, 1 874 (53.12%) in stage Ⅳ, and 382 (10.83%) unavailable. Surgery was performed on 2 255 patients (63.92%) . Three hundred and thirty-six patients received chemotherapy or radiotherapy (9.52%; of which 172 were palliative); 1 101 (31.21%) received only supportive treatment.The patient source, treatment and surgery, pathology, concomitant gallstone, and prognosis were analyzed. Results: Among the 3 528 GBC patients, 959 (27.18%) were from East China, 603 (17.09%) from East-North China, 1 533 (43.45%) from Central China, and 433(12.27%) from West China. Among the 1 578 resectable tumor, 665 (42.14%) underwent radical surgery, 913 (57.86%) underwent surgery that failed to follow the guidelines.Eight hundred and ninety-one (56.46%) patients were diagnosed before surgery, 254 (16.10%) during surgery, and 381 (24.14%) after surgery (time point of diagnosis couldn't be determined in 52 patients) .Among the 1 578 patients with resectable tumor, 759 (48.10%) had concomitant gallstone.Among the 665 patients underwent radical surgery, 69 (10.4%) showed positive resection margin, 510 (76.7%) showed negative resection margin, and 86 (12.9%) unreported margin status.The 5-year overall survival rate (5yOS) for the 3 528-patient cohort was 23.0%.The 5yOS for patients with resectable tumor was 39.6%, for patients with stage ⅣB tumor without surgery was 5.4%, and for patients with stage ⅣB tumor underwent palliative surgery was 4.7%. Conclusions: More than half GBC patients in China are diagnosed in stage Ⅳ.Curative intent surgery is valuable in improving prognosis of resectable GBC.The treatment of GBC needs further standardization.Effective comprehensive treatment for GBC is in urgent need.

Abstract
Objective: To investigate and analyze the current situation, screening, clinical characteristics, prevention and treatment of bleeding esophageal varices in cirrhotic patients with portal hypertension in Tibet region. Methods: Clinical data of cirrhotic patients with portal hypertension through March 2017 to February 2020 from Tibet region were collected and analyzed retrospectively. Results: 511 cases with liver cirrhosis were included in the study, of which 185 cases (36.20%) had compensated cirrhosis and 326 cases (63.80%) had decompensated cirrhosis. Further analysis of the etiological data of liver cirrhosis showed that 306 cases (59.88%) were of chronic hepatitis B, 113 cases (22.11%) of alcoholic liver disease, and 68 cases (13.31%) of chronic hepatitis B combined with alcoholic liver disease. Among patients with compensated liver cirrhosis, 48 cases (25.95%) underwent endoscopic examination of which 33 diagnosed as high-risk variceal bleeding. However, none of these 33 cases had received non-selective β-blocker therapy, and only four patients had received endoscopic variceal banding therapy. Among patients with decompensated liver cirrhosis, 83 cases (25.46%) had a history of upper gastrointestinal bleeding, 297 cases (91.10%) had ascites, 23 cases (7.05%) had hepatic encephalopathy, and 3 cases (0.92%) had hepatorenal syndrome. Among the patients with a history of upper gastrointestinal bleeding, 42 cases (50.60%) had received secondary preventive treatment for bleeding esophageal varices, including 39 cases of endoscopic treatment, 1 case of endoscopic combined drug treatment, 3 cases of interventional treatment, and 2 cases of surgical treatment. Conclusion: Chronic hepatitis B and alcoholic liver diseases are the main causes of liver cirrhosis in Tibet region. Moreover, this region lacks screening, prevention and treatment for bleeding esophageal varices in cirrhotic patients with portal hypertension. Therefore, it is necessary to increase the screening of high-risk groups to prevent and improve the first-time bleeding, and promote multidisciplinary team to prevent and treat re-bleeding.

Abstract
Objective: To investigate the therapeutic effect of programmed cell death receptor 1 (PD-1) inhibitor in drug-resistant recurrent gestational trophoblastic neoplasia (GTN). Methods: Clinicopathological features, previous treatments, PD-1 inhibitor treatment and prognosis of 8 patients with drug-resistant recurrent GTN treated with PD-1 inhibitor pembrolizumab, in Peking Union Medical College Hospital of Chinese Academy of Medical Sciences from August 2018 to June 2019 were collected and retrospectively analyzed. Results: (1) Clinicopathological features: the average age of onset of 8 GTN patients was 32.9 years old (31-39 years old); pathological types: choriocarcinoma in 7 cases, epithelioid trophoblastic tumor in 1 case. International Federation of Gynecology and Obstetrics (FIGO) stages: stage Ⅲ in 5 cases, stage Ⅳ in 3 cases; FIGO score: 4 patients with 7-12 points (high-risk group) and 4 patients with ≥13 points (ultra high-risk group). All the 8 patients had lung metastasis, 2 patients with brain metastasis, 1 patient with kidney and 1 patient with intestinal metastasis. (2) Previous treatments: ① Chemotherapy: 8 patients with GTN received an average of 21.1 courses (5-30 courses) of chemotherapy; the main route was systemic intravenous chemotherapy. One patient received intrathecal methotrexate chemotherapy due to brain metastasis. ② Surgery: 7 of 8 patients with GTN received surgical treatment, including 5 cases of pelvic surgury, 6 cases of pulmonary lobectomy and 1 case of right hemicolectomy. ③ Radiotherapy: 2 of 8 patients with GTN received radiotherapy, among which 1 patient received radiotherapy for lung for 8 times due to lung metastasis, and the other one received radiotherapy for lung, right sacroiliac joint and skull for a total of 22 times. (3) PD-1 inhibitor treatment: 8 patients with GTN received PD-1 inhibitor treatment with a mean course of 9 (2-12 courses). Six patients appeared Ⅰ-Ⅱ grade of immune related adverse events (AE), and no severe AE occurred. (4) Prognosis: after 2-3 courses of PD-1 inhibitor treatment, serum β-hCG level came to normalization in 4 patients. They were followed up for 2-7 months without any recurrence after 0-9 courses of consolidation treatment. One patient received 12 courses of PD-1 inhibitor treatment. The serum β-hCG level normalized after the 6th courses but increased 1 months later, and then received bevacizumab treatment due to the progression of the disease. The remaining 3 patients received other chemotherapy regiments due to disease progression during PD-1 inhibitor treatment. Conclusions: PD-1 could be used as a remedial treatment for drug-resistant recurrent GTN, with a high effective rate and relatively mild AE. However, more cases need to be accumulated clinically and efficacy should be comprehensively evaluated in combination with pathology and immunohistochemical examination.

Abstract
Apocynum venetum L. is a traditional Chinese medicinal herb with great potential to treat angiocardiopathy. Its major medicinal constituents are flavonoids. However, the natural habitats of A. venetum are typically affected by salt stress, which can modify both biomass and accumulation of medicinal compounds. In this study, the effects of salt stress on growth and development of A. venetum, accumulation of flavonoids and expression patterns of genes involved in flavonoid biosynthesis were evaluated. In general, the growth and development of seedlings (seedling height, root length, leaf length, leaf width and seed germination) were inhibited by salt stress. Unlike typical halophytes, there was no optimal NaCl concentration range that promoted growth and development, but seedlings had an elevated DW/FW ratio under salt stress (induced by irrigation with 50, 100, 200 or 400 mm NaCl). Furthermore, quercetin and kaempferol were significantly accumulated in A. venetum seedlings under salt stress, resulting in a balanced content and reduced FW. Moreover, the expression of AvCHS, AvCHI and AvF3GT was inhibited by salt stress; however, AvF3'H, AvF3H and AvFLS, which are involved in the flavonol synthesis pathway, were up-regulated under salt stress, consistent with a decrease in total flavonoids and an increase of flavonols (quercetin and kaempferol). In summary, cultivation of A. venetum in saline soils appeared to be feasible and improved the medicinal quality of A. venetum (quercetin and kaempferol accumulation under salt stress), thus this species can effectively utilize saline soil resources.

Abstract
Parathyroid hormone (PTH) is a crucial regulator of calcium homeostasis and bone remodeling, and the parathyroid hormone 1 receptor (PTH1R) belongs to a class II G-protein-coupled receptor. PTH activates PTH1R, which mediates catabolic and anabolic processes in the skeleton. However, the functional mechanism of PTH1R has not been thoroughly elucidated in organisms. This study identified a 51 bp indel mutation in the first intron of the PTH1R gene and elucidated the effect of this gene mutation on the growth and carcass traits in chickens. The results indicated that the 51 bp indel was significantly associated with subcutaneous fat thickness, abdominal fat weight, body weight and daily gain over 4-8 weeks. Furthermore, we found that PTH1R gene expression was highest in the kidney and liver tissues, and it showed a trend of decreasing in leg and breast muscle tissues at different embryonic stages. In addition, we examined the expression of the three genotypes of the PTH1R gene in the liver, breast muscle and abdominal fat and found that the II genotype was significantly higher than the DD and ID genotypes. In summary, these findings suggest that the PTH1R gene can serve as a potential molecular marker for chicken breeding.

Abstract
Retinal ganglion cell (RGC) degeneration, leading to irreversible blindness in chronic optic neuropathies, commonly begins with dendritic shrinkage followed by axon degeneration. Although limited axon regeneration in the optic nerve is possible with a genetic deletion of PTEN/SOCS3 after optic nerve injury, the roles of PTEN/SOCS3 on dendritic preservation and regeneration remain unclear. This study investigated the effect of PTEN/SOCS3 genetic deletion on the structural integrity of RGC dendrites and axons in the retina following optic nerve crush. Using time-lapse, in vivo confocal scanning laser ophthalmoscopy to serially image dendritic and axonal arborizations of RGCs over six months after injury, RGC dendrites and axons were only preserved in Thy-1-YFP/PTEN-/- and Thy-1-YFP/PTEN-/-SOCS3-/- mice, and axons in the retina regenerated at a rate of 21.1 μm/day and 15.5 μm/day, respectively. By contrast, dendritic complexity significantly decreased in Thy-1-YFP-SOCS3-/- and control mice at a rate of 7.0 %/day and 7.1 %/day, respectively, and no axon regeneration in the retina was observed. RGC survival probability was higher in Thy-1-YFP/PTEN-/- and Thy-1-YFP/PTEN-/-SOCS3-/- mice compared with Thy-1-YFP-SOCS3-/- and control mice. The differential responses between the transgenic mice demonstrate that although a genetic deletion of PTEN, SOCS3, or PTEN/SOCS3 allows partial axon regeneration in the optic nerve after optic nerve crush, a deletion of PTEN, but not SOCS3, ameliorates RGC dendritic shrinkage. This shows that the signaling pathways involved in promoting axon regeneration do not equally contribute to the preservation of dendrites, which is crucial to the translational application of neuroregenerative therapies for visual restoration.

Abstract
Objective: To examine minimally invasive tricuspid valve operations applied in tricuspid valve insufficiency patients with previous left-sided valve surgery. Methods: Between September 2017 and June 2019, thirty-six consecutive patients received minimally invasive totally thoracoscopic tricuspid surgery through right thoracotomy at Department of Cardiovascular Surgery, Fisrt Medical Center, People's Liberation Army General Hospital. There were 13 males and 23 females, aging (56±11) years (range: 43 to 79 years). All the patients had isolated significant tricuspid regurgitation after previous left-sided cardiac surgeries. A right anterolateral thoracotomy incision about 4 cm was made from the fourth intercostal space as main operating port. The arterial cannula was placed in femoral artery. The venous cannula was placed in femoral vein using Seldingger technique. Tricuspid valve operation was performed on beating heart by assist of vena vacuum. Results: Tricuspid valve repair was performed in 7 patients. Tricuspid valve replacement with bioprosthesis was performed in 29 patients. The operation time was (2.9±0.3) hours (range:2.5 to 3.6 hours). There was no conversion to sternotomy during operation. There was no severe complications during operation period. There were no complications related to this cannulation technique. The time of cardiopulmonary bypass establishment was (22±5) minutes (range: 12 to 24 minutes) and pump time was (82±16) minutes (range: 62 to 93 minutes). The length of hospital stay was (9±3) days after operation (range: 5 to 13 days). There was no early death in hospital. All patients were followed up for 3 to 22 months. No patient died. Conclusions: One single port-based minimally invasive approach seems to be safe, feasible, and reproducible in case of redo tricuspid valve operations. Only cannulation of inferior vena cava significantly simplified the complexity of isolated redo tricuspid surgery.

Abstract
Microtia is a congenital malformation of the external ear that can be observed in many species including sheep. However, the genetic basis of microtia still remains unclear. Here, a GWAS was conducted to investigate the genetic basis underlying microtia. A total of 55 samples from 26 microtia and 29 normal animals were genotyped with Illumina OvineHD BeadChip. The strongest significant SNP was identified on OAR6, approximating the evolutionarily conserved region of the HMX1 gene, which is related to congenital malformations of the external ear in other species such as cattle and rats. Sequencing an evolutionarily conserved region surrounding HMX1 revealed a duplication of 76 bp, which is concordant with microtia, suggesting a dominant inheritance mode. Identification of this causal mutation in the HMX1 gene indicates the role of this particular gene in the development of the external ear and provides a genetic marker for selection against microtia.

Abstract
To investigate the current status of postgraduates training in public health and preventive medicine in China. In this study, a questionnaire survey was conducted among directors of enrollment and teaching in 22 universities with postgraduate admission qualifications in corresponding disciplines nationwide. In 2016, full-time postgraduates were mainly academic masters. In addition to the graduate entrance examination, the common enrollment mode in colleges was to enroll a high qualified student with recommendations from relevant experts or institutions and an exemption from entrance examination (20/22). The emphasis on training contents between academic and public health master was different. Currently, the scale of public health postgraduate enrollment in public health and preventive medicine in China is stable, and the training program is reasonable, but there is an issue of monotonous model and uneven distribution of enrollment.

Abstract
In order to understand the status of the cultivation of the masters of public health (MPH) in colleges in China and improve the cultivation model, an electronic questionnaire survey were conducted among 22 schools of public health in colleges. The result showed that the size and the enrolment scale of Chinese MPH students were relatively small, and the training objectives were still unclear. There was no obvious difference between the curriculum setting for MPH and academic master degree. The practical skill-oriented courses and emergency response ability of public health practice were insufficient. The cultivation model of MPH should be improved in future.

Abstract
Investigation of neurodegeneration in glaucoma, a leading cause of irreversible blindness worldwide, has been obfuscated by the lack of an efficient model that provides chronic, mild to moderate elevation of intraocular pressure (IOP) with preservation of optical media clarity for long term, in vivo interrogation of the structural and functional integrity of the retinal ganglion cells (RGCs). Here, we designed and formulated an injectable hydrogel based on in situ cross-linking of hyaluronic acid functionalized with vinyl sulfone (HA-VS) and thiol groups (HA-SH). Intracameral injection of HA-VS and HA-SH in C57BL/6J mice exhibited mild to moderate elevation of IOP with daily mean IOP ranged between 14 ± 3 and 24 ± 3 mmHg, which led to progressive, regional loss of RGCs evaluated with in vivo, time-lapse confocal scanning laser ophthalmoscopy; a reduction in fractional anisotropy in the optic nerve and the optic tract projected from the eye with increased IOP in diffusion tensor magnetic resonance imaging; a decrease in positive scotopic threshold response in electroretinography; and a decline in visual acuity measured with an optokinetic virtual reality system. The proportion of RGC loss was positively associated with the age of the animals, and the levels and the duration of IOP elevation. The new glaucoma model recapitulates key characteristics of human glaucoma which is pertinent to the development and pre-clinical testing of neuroprotective and neuroregenerative therapies. STATEMENT OF SIGNIFICANCE: A new model to study chronic neurodegeneration in glaucoma has been developed via intracameral injection of a specifically designed hyaluronic acid functionalized with vinyl sulfone and thiol groups for cross-linking. Intracameral injection of the chemically cross-linked hydrogel generates mild to moderate IOP elevation, resulting in progressive degeneration of the retinal ganglion cells, optic nerve, and optic tract, and a decline in visual function. The model recapitulates the key features of neurodegeneration in human glaucoma, which will facilitate and expedite the development of neuroprotective and neuroregenerative therapies.

Abstract
Objective: To analyze the clinicopathological features and prognosis of patients in endometrial cancer with bone metastases. Methods: A retrospective review of medical records was performed to analyze patients with endometrial cancer who developed bone metastases at Peking Union Medical College Hospital (PUMCH) from January 2004 to December 2017, including patients with bone metastases at the diagnosis of endometrial cancer and at recurrence of endometrial cancer. The patient's clinicopathological features, bone metastasis characteristics, treatment process and prognoses were also analyzed. Results: The incidence of bone metastasis of endometrial cancer in PUMCH from 2004 to 2017 was 0.57% (14/2 458). (1) General clinical pathological features: the median age of the 7 patients with bone metastases diagnosed at the time of initial diagnosis was 50 years old, and the main pathological type was endometrioid carcinoma (n=5). The median age of the other 7 patients was 57 years old, with no significant difference comparing to the former groups (P=0.559). (2) The majority site of bone metastasis in endometrial cancer were discovered in pelvic bones, followed by the tibia. (3) Treatment: according to the staging of endometrial cancer, a comprehensive treatment based on surgery was performed, and one patient with isolated bone metastases underwent resection of bone metastasis. (4) Prognosis: nine out of the 14 patients died during the follow-up period. The median over all survival time was 25.5 months (range: 7.7-258.0 months). The median survival of population after diagnosis of bone metastases was 15.0 months (range: 3.0-51.0 months). The survival rate of endometrial cancer at 1-year after diagnosis of bone metastasis was 71.4%. The 2-year survival rate was 40.8%. (5) No independent prognostic factors affecting survival was found (P>0.05). Conclusions: The incidence of bone metastasis in endometrial cancer is less than 1%. Bone metastasis could occur at the diagnosis of endometrial cancer or recurrence of endometrial cancer. Bone metastasis suggests a poor prognosis. There is no standard follow-up and treatment protocols so that individualized treatment is needed.

Abstract
Glutaminyl-peptide cyclotransferase-like (QPCTL) is an isoenzyme of glutaminyl-peptide cyclotransferase (QPCT). QPCTL and QPCT catalyze the formation of N-terminal modified pyroglutamate-fractalkine and the chemokine CCL2. The objective of this study was to investigate the association between insertions/deletions in the chicken QPCTL promoter region with growth traits in chickens. We first detected two insertion/deletion variants of QPCTL via whole-genome resequencing analysis of DNA samples from Xichuan chickens. A total of 1896 individuals from 12 breeds were genotyped for 52- and 224-bp insertions/deletions. We found two novel insertions/deletions in the promoter region of the chicken QPCTL gene and studied their association with chicken body weight and carcass traits. Our findings show that QPCTL can be a molecular marker for chicken genetics and breeding programs.

Abstract
Objective: To analyze the prevalence and related factors of HBV infection among people aged 18 years old and above in Mianyang city. Methods: A total of 260 950 residents, living in Mianyang city more than 6 months, aging 18 years old and above were employed by multi-stage random sampling method from November 2014 to September 2015. Questionnaire survey was conducted on participants using a self-designed questionnaire, including general demographic characteristics, family history of Hepatitis B, history of Hepatitis B vaccination and history of present illness, etc. 5ml blood was collected from all participants, and the blood samples were detected for HBsAg by enzyme-linked immunosorbent assay (ELISA). The multivariate unconditional logistic regression was performed to identify the related factors of positive HBsAg. Results: Among the 260 950 subjects, 113 184 were males (43.37%), 147 766 were females (56.63%), and the average age was (47.68±17.36) years old. The positive rate of HBsAg was 6.10%(15 822 cases). Subjects who were 25-34 years old (OR=1.23), 35-44 years old (OR=1.26), 45-54 years old (OR=1.23), and 55-64 years old (OR=1.34) were more likely to be HBsAg positive,65 years and older (OR=0.88) were less likely to be, compared with subjects aging 18-24 years old; males were more likely to be HBsAg positive compared with females (OR=1.35); people living in Fucheng district were more likely to be HBsAg positive compared with who living in Jiangyou district(OR=1.91); married people were more likely to be HBsAg positive compared with unmarried ones (OR=1.36); medical staff were less likely to be HBsAg positive compared with non-medical staff (OR=0.61); subjects with a surgery history were more likely to HBsAg positive compared with who without (OR=1.13); subjects with trauma history were more likely to HBsAg positive compared with who without (OR=1.13); people with history of Hepatitis B were more likely to HBsAg positive compared with who without (OR=4.21); people with Hepatitis B vaccination history were less likely to be HBsAg positive compared with who without (OR=0.48); all the P values above were less than 0.05. Conclusion: The positive rate of HBsAg among adults in Mianyang city was very high, and we should pay more attention to people aging between 25 and 64 years old, male, medical staff, with surgery history, trauma history, and a family history of Hepatitis B and Hepatitis B vaccination history.

Abstract
Objective: Using a questionnaire to evaluate different regimens of chemotherapy on ovarian function and quality of life of patients with gestational trophoblastic neoplasia (GTN) . Methods: At least 6 months after completion of chemotherapy, 200 patients with GTN treated in Peking Union Medical College Hospital from January 2010 to June 2017 were randomly selected to fill up the questionnaire. The questionnaire items were included the patient's menstrual cycles, sexual life, gestational issues and common health. The patients were divided into 3 groups by chemotherapy regimens: actinomycin D (Act-D) group, floxuridine+Act-D+vincristine (FAV) or floxuridine+Act-D+etoposide+vincristine (FAEV) group (FAV-FAEV group) , and etoposide+methotrexate+Act-D (EMA) /vincristine+cyclophosphamide (CO) or EMA/ etoposide+cisplatin (EP) group (EMA/CO-EMA/EP group) . Chi-square test was used with a significance level of P-value less than 0.05. Results: One hundred and seventy-three (86.5%,173/200) of the patients completed the questionnaire. Forty three point two percent (43.2%, 19/44) in the EMA/CO-EMA/EP group had a normal menstrual cycle, which were significantly lower than those of Act-D group (84.6%,22/26) and FAV-FAEV group (71.2%, 37/52; all P<0.05) . Amenorrhea rate was also significantly higher in EMA/CO-EMA/EP group (25.0%, 11/44) than in Act-D group (0) and FAV-FAEV group (17.3%, 9/52; all P<0.05) . The sexual life parameters were comparable among 3 groups. Ten out of thirty-two patients conceived after chemotherapy, 2 had miscarriages and 8 had full-term delivery of healthy babies. The common health and labor capacity were significantly decreased after chemotherapy (all P<0.05) . Conclusions: EMA/CO or EMA/EP regimen have a worse impact on ovarian function than Act-D and FAV or FAEV regimen. Gynecologic oncologist should be concerned about the ovarian function and quality of life of GTN patients.

Abstract
Objective: To summarize and analyze the clinical outcomes of gestational trophoblastic neoplasia (GTN) patients receiving primary treatment at Peking Union Medical College Hospital from 1985 to 2015, and investigate the changes in treatment efficacy between the first and the second 15 years. Methods: Clinical data of GTN patient receiving primary chemotherapy at Peking Union Medical College Hospital from January 1985 to December 2015 were retrospectively analyzed. It further compared the therapeutic results and chemotherapy cycles given to GTN patients, according to International Federation of Gynecology and Obstetrics (FIGO, 2000) prognostic score system, who were classified to different stages and low- or high-risk groups. Results: In total, 1 711 GTN patients were included in this study. Comparing the 1985-2000 group and the 2001-2015 group, the results showed that: (1) while the overall complete remission (CR) rate was 93.7% (1 603/1 711) , the CR rate of 2001-2015 group was significantly higher than that of 1985-2000 group [98.4% (1 155/1 174) vs 83.4% (448/537) , χ(2)=139.353, P<0.01]. This difference was significant between stage Ⅲ and Ⅳ patients, but nonexistent between stage Ⅰ and Ⅱ patients, including low- and high-risk groups. (2) The relapse rate of patients who had been in CR was 2.7% (43/1 603) , with no significant differences between the groups of 1985-2001 and 2001-2015 [3.6% (16/448) vs 2.3% (27/1 155) , χ(2)=6.867, P=0.142]. (3) The overall mortality rate was 2.6% (44/1 711) , which significantly decreased in 2001-2015 group compared to 1985-2000 group [1.6% (19/1 174) vs 4.7% (25/537) , χ(2)=13.830, P<0.01]. This difference appeared only in high-risk patients with stage Ⅲ disease (χ(2)=9.505, P<0.01) . (4) Fluorouracil was gradually replaced by floxridine in chemotherapy regimens. The total cycles of chemotherapy regimens given to low-risk patients with stage Ⅲ disease significantly decreased in 2001-2015 group, but no statistical difference was shown with patients at other stages. Moreover, the cycles of consolidation treatment were significantly reduced in patients with stage Ⅲ patients. Conclusions: GTN patients could obtain satisfactory curative results after appropriate and standard treatment. Peking Union Medical College Hospital has achieved better curative effect in the latest 15 years than before.

Abstract
We explore the effect of microbial activity stimulated by root exudates on the penetrometer resistance of soil and its elastic modulus. This is important because it is a measure of the mechanical strength of soil and it correlates closely with the rate of elongation of roots. A sandy soil was incubated with a synthetic root exudate at different temperatures, for different lengths of time and with selective suppression of either fungi or bacteria. The shape of the temperature response of penetrometer resistance in soil incubated with synthetic exudate was typical of a poikilothermic temperature response. Both penetrometer resistance and small strain shear modulus had maximum values between 25 and 30°C. At temperatures of 20°C and less, there was little effect of incubation with synthetic root exudate on the small strain shear modulus, although penetrometer resistance did increase with temperature over this range (4-20°C). This suggests that in this temperature range the increase in penetrometer resistance was related to a greater resistance to plastic deformation. At higher temperatures (> 25°C) penetrometer resistance decreased. Analysis of the DNA sequence data showed that at 25°C the number of Streptomyces (Gram-positive bacteria) increased, but selective suppression of either fungi or bacteria suggested that fungi have the greater role with respect to penetrometer resistance. HIGHLIGHTS Effect of microbial activity stimulated by synthetic root exudates on the mechanical properties.We compared penetrometer measurements and estimates of elastic modulus with microbial community.Penetrometer resistance of soil showed a poikilothermic temperature response.Penetrometer resistance might be affected more by fungi than bacteria.

Abstract
Objective: To discuss the effects of prophylactic chemotherapy on the outcomes and prognosis of invasive mole patients. Methods: One hundred and fifteen invasive mole (IM) patients older than 40 years were registered in Peking Union Medical Collage Hospital.Eleven of them were treated with prophylactic chemotherapy before diagnosed as IM prophylactic chemotherapy group, while the other 104 cases received therapeutic chemotherapy after diagnosed as IM (non-prophylactic chemotherapy group). The general clinical data (including age, clinical stage, risk factor score), treatment, outcomes and relapse of patients were retrospectively compared between two groups. Results: (1) The age of prophylactic chemotherapy group and non-prophylactic chemotherapy group were (47±5) versus (46±4) years old. Ratio of clinical stageⅠ-Ⅱ were 3/11 versus 29.8% (31/104), clinical stage Ⅲ-Ⅳ were 8/11 versus 70.2% (73/104). Ratio of risk factor score 0-6 were 11/11 versus 84.6% (88/104), risk factor score >6 were 0 versus 15.4% (16/104). There were no significant statistical differences between two groups in age, clinical stage or risk factor score (all P>0.05). (2) Treatment: the total chemotherapy courses between prophylactic chemotherapy group and non-prophylactic chemotherapy group (median 7 versus 5) were significantly different (Z=3.071,P=0.002). There were no significant statistical differences between two groups in the chemotherapy courses until negative conversion of β-hCG, consolidation chemotherapy courses, total therapeutic chemotherapy courses or ratio of hysterectomy (all P>0.05). (3) Outcomes and relapse: between the prophylactic chemotherapy group and the non-prophylactic chemotherapy group, the complete remission rate were 11/11 versus 98.1%(102/104), the relapse rate were 0 versus 1.0%(1/102). There were no significant difference between the two groups in outcomes or relapse rate (P>0.05). Conclusions: Prophylactic chemotherapy does not substantially benefit the IM patients older than 40 years. Prophylactic chemotherapy may not significantly improve patients' prognosis, in which increased sample size is required in further study.

Abstract
Objective: To investigate the possibility of the Protein Phosphatase 2A (PP2A) inhibitor, LB100, in reversing acquired resistance to gefitinib in lung adenocarcinoma with epidermal growth factor receptor (EGFR) gene mutation. Methods: Cell line NCI-H1975 and established primary culture cell line 44-1 with gefitinib resistance were sequenced to determine the mutation type of EGFR gene. Cells were treated with gefitinib alone or combined with LB100 to determine the half maximal inhibitory concentration (IC50), and sensitivity of 44-1 and NCI-1975 to gefitinib alone or combined with LB100 was compared. The volume of NCI-H1975 xenografts with different drug treatments was observed to determine the efficiency of gefitinib with or without LB100 in tumor growth inhibition. Results: Both 44-1 and NCI-1975 cells had double EGFR mutation (sensitive L858R mutation and resistant T790M mutation). Both cells showed significant gefitinib resistance (IC50: 23.0 μmol/L in 44-1, 16.7 μmol/L in NCI-1975). When combined with LB100, IC50 of gefitinib decreased to 6.9 μmol/L in 44-1 cell and decreased to 3.4 μmol/L in NCI-H1975 cells. In NCI-1975 xenografts experiments, LB100 enhanced the ability of gefitinib in tumor growth inhibition (P<0.05). Conclusion: LB100 reverses acquired resistance to gefitinib in lung adenocarcinoma cell lines.

Abstract
The acute respiratory distress syndrome (ARDS), a clinical complication of severe acute lung injury (ALI) in humans, is a leading cause of morbidity and mortality in critically ill patients. Here, we explored the association between IL-17 and development of ALI using LPS-induced murine model. We found that IL-17 level was elevated in bronchoalveolar lavage (BAL) fluid of ALI mice. Upregulation of IL-17 resulted in increased severity of ALI as evidenced by decreased body weight and survival rate, elevated level of total protein and albumin in BAL fluid, as well as more apparent histopathology changes of lung. Induction of ALI was impaired in IL-17-deficient mice. Management of IL-17 could modulate LPS-induced pulmonary inflammation, as reflected by the total cell and neutrophil counts, proinflammatory cytokines, as well as chemokines in BAL fluid. Of note, blockade of IL-17 effectively inhibited the lung inflammation and alleviated ALI severity. Finally, we confirmed the clinical relevance and found that IL-17 expression was elevated and associated with the disease severity in patients with ARDS. In essence, IL-17 was crucial for development of ALI, suggesting a potential application for IL-17-based therapy in clinical practice.

Abstract
In this opinion article we examine the relationship between penetrometer resistance and soil depth in the field. Assuming that root growth is inhibited at penetrometer resistances > 2.5 MPa, we conclude that in most circumstances the increases in penetrometer resistance with depth are sufficiently great to confine most deep roots to elongating in existing structural pores. We suggest that deep rooting is more likely related to the interaction between root architecture and soil structure than it is to the ability of a root to deform strong soil. Although the ability of roots to deform strong soil is an important trait, we propose it is more closely related to root exploration of surface layers than deep rooting.

Abstract
UNLABELLED As a paramyxovirus, Newcastle disease virus (NDV) has the ability to edit its P (phosphoprotein) gene to synthesize three kinds of viral protein (P, V and W). It is technically very difficult to differentiate P, V and W mRNAs, and little was known about NDV regulation of RNA-editing frequency. To investigate the rules of NDV RNA editing, the ratio of the P gene-derived transcripts (P, V and W) was determined by sequencing at different time points post-infection. The results showed unstable ratio of V and W mRNA at different time points, and the frequency of NDV editing was significantly increased at the early period of infection (P KEYWORDS Newcastle disease virus; phosphoprotein; RNA editing; G insertion.

Abstract
Reduction-oxidation (redox) active molecules hold potential for memory devices due to their many unique properties. We report the use of a novel diruthenium-based redox molecule incorporated into a non-volatile Flash-based memory device architecture. The memory capacitor device structure consists of a Pd/Al2O3/molecule/SiO2/Si structure. The bulky ruthenium redox molecule is attached to the surface by using a 'click' reaction and the monolayer structure is characterized by x-ray photoelectron spectroscopy to verify the Ru attachment and molecular density. The 'click' reaction is particularly advantageous for memory applications because of (1) ease of chemical design and synthesis, and (2) provides an additional spatial barrier between the oxide/silicon to the diruthenium molecule. Ultraviolet photoelectron spectroscopy data identified the energy of the electronic levels of the surface before and after surface modification. The molecular memory devices display an unsaturated charge storage window attributed to the intrinsic properties of the redox-active molecule. Our findings demonstrate the strengths and challenges with integrating molecular layers within solid-state devices, which will influence the future design of molecular memory devices.

Abstract
PURPOSE To determine the levels of Th17-associated cytokines, particularly interleukin (IL)-17 and IL-22 in tears of patients with dry eye syndrome. METHODS Tear samples were collected from 20 healthy volunteers, 20 dry eye (DE) patients with non-Sjögren's syndrome (NSSDE) and 20 DE patients with Sjögren's syndrome (SSDE). Symptom questionnaire was self-administered and multiple dry eye disease (DED)-related clinical tests were performed. The levels of IL-17 and IL-22 in tears were measured by enzyme-linked immunosorbent assay. RESULTS The levels of IL-17 and IL-22 were significantly increased in tears of DE patients compared with those of controls and also higher in SSDE patients compared with those of NSSDE patients (P<0.05). Moreover, the levels of IL-17 and IL-22 were positively correlated with questionnaire score and keratopathy score but negatively correlated with tear film break-up time and Schirmer I test in both NSSDE and SSDE patients (P<0.05). CONCLUSIONS The levels of IL-17 and IL-22 in tears were significantly increased in DE patients, which were associated with the disease severity. Therefore, Th17 cell-associated cytokines, particularly IL-17 and IL-22, may have important roles in the immunopathogenesis of the DED.
