Abstract
Bone loss is a major issue for patients with osteoporosis, arthritis, periodontitis, and bone metastasis; however, anti-resorption drugs used to treat bone loss have been linked to a variety of adverse effects. Helminthostachys zeylanica (L.) Hook, belonging to the family Ophioglossaceae, is commonly used in traditional Chinese medicine to treat inflammation and liver problems. In the current study, ugonin L extracted from H. zeylanica was shown to reduce the receptor activator of nuclear factor kappa beta ligand (RANKL)-induced osteoclastogenesis in RAW264.7 cells in a concentration-dependent manner. Ugonin L treatment also inhibited the mRNA expression of osteoclast markers. Ugonin L was also shown to promote cell apoptosis in mature osteoclasts and suppress RANKL-induced ERK, p38, JNK, and NF-κB activation. Taken together, ugonin L appears to be a promising candidate for the development of novel anti-resorption therapies.

Abstract
Lymph node metastasis is a recognized prognostic factor in esophageal cancer. Adipokines, including visfatin, and the molecule vascular endothelial growth factor (VEGF)-C, are implicated in lymphangiogenesis, but whether any association exists between esophageal cancer, adipokines and VEGF-C is unknown. We examined the relevance of adipokines and VEGF-C in esophageal squamous cell carcinoma (ESCC) in the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases. We found significantly higher levels of visfatin and VEGF-C expression in esophageal cancer tissue than in normal tissue. Immunohistochemistry (IHC) staining identified that higher levels of visfatin and VEGF-C expression were correlated with advanced stage ESCC. Visfatin treatment of ESCC cell lines upregulated VEGF-C expression and VEGF-C-dependent lymphangiogenesis in lymphatic endothelial cells. Visfatin induced increases in VEGF-C expression by activating the mitogen-activated protein kinase kinases1/2-extracellular signal-regulated kinase (MEK1/2-ERK) and Nuclear Factor Kappa B (NF-κB) signaling cascades. Transfecting ESCC cells with MEK1/2-ERK and NF-κB inhibitors (PD98059, FR180204, PDTC, and TPCK) and siRNAs inhibited visfatin-induced increases in VEGF-C expression. It appears that visfatin and VEGF-C are promising therapeutic targets in the inhibition of lymphangiogenesis in esophageal cancer.

Abstract
Bone metastases during lung cancer are common. Bone sialoprotein (BSP), a non-collagenous bone matrix protein, plays important functions in bone mineralization processes and in integrin-mediated cell-matrix interactions. Importantly, BSP induces bone metastasis in lung cancer, but the underlying mechanisms remain unclear. This study therefore sought to determine the intracellular signaling pathways responsible for BSP-induced migration and invasion of lung cancer cells to bone. Analyses of the Kaplan-Meier, TCGA, GEPIA and GENT2 databases revealed that high levels of BSP expression in lung tissue samples were associated with significantly decreased overall survival (hazard ratio = 1.17; p=0.014) and with a more advanced clinical disease stage (F-value = 2.38, p<0.05). We also observed that BSP-induced stimulation of matrix metalloproteinase (MMP)-14 promoted lung cancer cell migration and invasion via the PI3K/AKT/AP-1 signaling pathway. Notably, BSP promoted osteoclastogenesis in RAW 264.7 cells exposed to RANKL and BSP neutralizing antibody reduced osteoclast formation in conditioned medium (CM) from lung cancer cell lines. Finally, at 8 weeks after mice were injected with A549 cells or A549 BSP shRNA cells, the findings revealed that the knockdown of BSP expression significantly reduced metastasis to bone. These findings suggest that BSP signaling promotes lung bone metastasis via its direct downstream target gene MMP14, which reveals a novel potential therapeutic target for lung cancer bone metastases.

Abstract
Lung cancer is an extremely common cancer and metastatic lung cancer has a greatly low survival rate. Lymphangiogenesis is essential for the development and metastasis of lung cancer. The adipokine angiopoietin-like protein 2 (ANGPTL2) regulates tumor progression and metastasis, although the functions of ANGPTL2 in lung cancer are unknown. Analysis of data from TCGA genomics program, the GEPIA web server and the Oncomine database revealed that higher levels of ANGPTL2 expression were correlated with progressive disease and lymph node metastasis. ANGPTL2 enhanced VEGF-A-dependent lymphatic endothelial cell (LEC) tube formation and migration. Integrin α5β1, p38 and nuclear factor (NF)-κB signaling mediated ANGPTL2-regulated lymphangiogenesis. Importantly, overexpression ANGPTL2 facilitated tumor growth and lymphangiogenesis in vivo. Thus, ANGPTL2 is a promising therapeutic object for treating lung cancer.

Abstract
Chondrosarcoma is the second most common type of bone cancer. Surgical resection is the best choice for clinical treatment. High-grade chondrosarcoma is destructive and is more possible to metastasis, which is difficult to remove using surgery. Doxorubicin (Dox) is the most commonly used chemotherapy drug in the clinical setting; however, drug resistance is a major obstacle to effective treatment. In the present study, we compared Dox-resistant SW1353 cells to their parental cells using RNA sequencing (RNA-Seq). We found that the apelin (APLN) pathway was highly activated in resistant cells. In addition, tissue array analysis also showed that APLN was higher in high-grade tissues compared to low-grade tissues. APLN is a member of the adipokine family, which is a novel secreted peptide with multifunctional and biological activities. Previously, studies have shown that inhibition of the APLN axis may have a therapeutic benefit in cancers. However, the role of APLN in chondrosarcoma is completely unclear, and no related studies have been reported. During in vitro experiments, APLN was also observed to be highly expressed and secreted in Dox-resistant cells. Once APLN was knocked down, it could effectively improve its sensitivity to Dox. We also explored possible upstream regulatory microRNAs (miRNAs) of APLN through bioinformatics tools and the results disclosed that miR-631 was the most likely regulator of APLN. Furthermore, the expression of miR-631 was lower in the resistant cells, but overexpression of miR-631 in the Dox-resistant cell lines significantly increased the Dox sensitivity. These results were also observed in another chondrosarcoma cell line, JJ012 cells. Taken together, these findings will provide rationale for the development of drug resistance biomarkers and therapeutic strategies for APLN pathway inhibitors to improve the survival of patients with chondrosarcoma.

Abstract
BACKGROUND Percutaneous cervical nucleoplasty (PCN) is a simple, safe, and effective treatment for contained cervical herniated intervertebral disc (CHIVD). However, few studies have compared the actual benefits of PCN against conservative treatment (CT), either clinically or radiographically. PURPOSE The present study sought to analyze and to compare the outcomes of symptomatic contained CHIVD treated with PCN or CT. METHODS The present study was designed as a case-control comparative study. Patients who indicated for PCN after a failed CT for more than 6 months were recruited. After the exclusion of some patients who did not meet the selection criteria of the study, we finally enrolled 71 patients treated with PCN. In addition, another 21 patients who indicated for PCN but finally chose to receive CT continuously were also enrolled and categorized as the control group. All patients completed the 6-month follow-up. Pain levels and functional outcomes were evaluated pre- and post-operatively by assessing the visual analog scale (VAS), Oswestry Disability Index (ODI), and Neck Disability Index (NDI). Radiographic images of 72 of 104 intervened segments were collected to measure disc height and other cervical spinal alignments, such as range of motion, C2-7 Cobb's angle, and C2-7 sagittal vertical axis. RESULTS Compared with the CT group, the PCN group showed significantly better outcomes on VAS, ODI, and NDI at the 1-month post-operative follow-up, which continued through at least the 6-month follow-up (P < 0.01 for VAS and P < 0.05 for ODI and NDI). The mean disc height significantly decreased, from 6.04 ± 0.85 mm to 5.76 ± 1.02 mm, 3 months after PCN treatment (P = 0.003). However, the degree of disc height decrease did not correlate with the changes of the substantial VAS improvement. CONCLUSIONS To provide therapeutic benefits for symptomatic contained CHIVD patients after an invalid CT for 6 months, PCN seems to be a better option than CT. The reduced disc heights did not alter the clinical outcomes of PCN.

Abstract
BACKGROUND Discussing the quality measurements based on interrupted time series in ischemic stroke, delays are often attributed to weekends effect. This study compared the metrics and outcomes of emergent endovascular thrombectomy (EST) during working hours versus non-working hours in the emergency department of an Asian medical center. METHODS A total of 297 patients who underwent EST between January 2015 and December 2018 were retrospectively included, with 52.5% of patients presenting during working hours and 47.5% presenting during nights, weekends, or holidays. RESULTS Patients with diabetes were more in non-working hours than in working hours (53.9% vs. 41.0%; p=0.026). It took longer during nonworking hours than working hours in door-to -image times (13 min vs. 12 min; p=0.04) and door-to-groin puncture times (median: 112 min vs. 104 min; p=0.042). Significant statistical differences were not observed between the two groups in neurological outcomes, including successful reperfusion and complications such as intracranial hemorrhage and mortality. However, the change in National Institute of Health Stroke Scale (NIHSS) scores in 24 hours was better in the working-hour group than in the nonworking-hour group (4 vs. 2; p=0.058). CONCLUSION This study revealed that nonworking-hour effects truly exist in patients who received EST. Although delays in door-to-groin puncture times were noticed during nonworking hours, significant differences in neurological functions and mortality were not observed between working and non-working hours. Nevertheless, methods to improve the process during non-working hours should be explored in the future.

Abstract
Men who have sex with men (MSM) is a group of people at high risk for HIV infection in China, Pre-exposure prophylaxis (PrEP) is a bioprophylaxis strategy in the prevention of HIV infection in MSM, which can reduce the risk for HIV infection in this population effectively. However, in the paractice, the use level of PrEP in MSM is low in China, and there are MSM who know PrEP but receive no PrEP. This paper summarizes the current status of the awareness, willingness to use, actual use of PrEP in MSM and influencing factors both at home and abroad to provide a reference for the promotion of PrEP use in MSM in China.

Abstract
Malignant brain tumors consist of malignancies originated primarily within the brain and the metastatic lesions disseminated from other organs. In spite of intensive studies, malignant brain tumors remain to be a medical challenge. Patient-derived organoid (PDO) can recapitulate the biological features of the primary tumor it was derived from and has emerged as a promising drug-screening model for precision therapy. Here we show a proof-of-concept based on early clinical study entailing the organoids derived from the surgically resected tumors of 26 patients with advanced malignant brain tumors enrolled during December 2020 to October 2021. The tumors included nine glioma patients, one malignant meningioma, one primary lymphoma patient, and 15 brain metastases. The primary tumor sites of the metastases included five from the lungs, three from the breasts, two from the ovaries, two from the colon, one from the testis, one of melanoma origin, and one of chondrosarcoma. Out of the 26 tissues, 13 (50%) organoids were successfully generated with a culture time of about 2 weeks. Among these patients, three were further pursued to have the organoids derived from their tumor tissues tested for the sensitivity to different therapeutic drugs in parallel to their clinical care. Our results showed that the therapeutic effects observed by the organoid models were consistent to the responses of these patients to their treatments. Our study suggests that PDO can recapitulate patient responses in the clinic with high potential of implementation in personalized medicine of malignant brain tumors.

Abstract
Advanced prostate cancer often develops into bone metastasis, which is characterized by aberrant bone formation with chronic pain and lower chances of survival. No treatment exists as yet for osteoblastic bone metastasis in prostate cancer. The indolamine melatonin (N-acetyl-5-methoxytryptamine) is a major regulator of the circadian rhythm. Melatonin has shown antiproliferative and antimetastatic activities but has not yet been shown to be active in osteoblastic bone lesions of prostate cancer. Our study investigations reveal that melatonin concentration-dependently decreases the migratory and invasive abilities of two osteoblastic prostate cancer cell lines by inhibiting FAK, c-Src, and NF-κB transcriptional activity via the melatonin MT1 receptor, which effectively inhibits integrin α2 β1 expression. Melatonin therapy appears to offer therapeutic possibilities for reducing osteoblastic bone lesions in prostate cancer.

Abstract
Objective: To examine the effectiveness and safety of application of the ureteral access sheath in the treatment of middle or lower ureteral calculi in patients with large-volume benign prostatic hyperplasia above grade Ⅲ, which is expected to avoid the simultaneous or staged treatment of benign prostatic hyperplasia via eliminate the difficult angle and resistance of ureteroscopy caused by severe prostatic hyperplasia. Methods: From April 2018 to December 2020, the clinical data of 27 patients with massive benign prostatic hyperplasia above grade Ⅲ and middle and lower ureteral calculi treated with indwelling ureteral access sheath plus ureteroscopy holmium laser lithotripsy at Department of Urology, Zhejiang Quhua Hospital were retrospectively analyzed and followed up. All the patients were male, aged (69.7±12.8) years (range: 55 to 87 years). Prostate volume measured by transrectal ultrasound was (94.8±16.2) cm3 (range: 85 to 186 cm3). The ureteral access sheath was indwelled in advance, and then the semirigid ureteroscopy was introduced through the working channel of the sheath. Holmium laser lithotripsy was performed, and intraoperative and postoperative complications were recorded. Urinary abdominal plain X-ray or CT urography were performed at 1-and 2-month postopaerative to evaluate the residual stones and clinical efficacy. Results: The ureteral access sheath was placed and holmium laser lithotripsy under a semirigid ureteroscopy was performed successfully in all the 27 patients. In 2 patients, a second session of auxiliary procedure was required due to the large load of preoperative stones and residual stones after surgery, among whom 1 patient received extracorporeal shock wave lithotripsy and 1 patient underwent extracorporeal shock wave lithotripsy plus ureteroscopic lithotripsy. The stone free rate at 1-and 2-month postoperative were 92.6% (25/27) and 100% (27/27), respectively. There were no severe complications such as ureteral avulsion and perforation, perirenal hematoma, septic shock, severe hematuria, urinary retention, iatrogenic ureteral stricture occurred during and after the surgery. The ureteral calculus was wrapped by polyps heavily in 1 patient, he was diagnosed as ureteral stenosis 1 month postoperative, receiving laparoscopic resection of ureteral stricture plus anastomosis 3 months postoperative. Conclusions: In the operations of middle and lower ureteral calculi in patients with large-volume prostatic hyperplasia above grade Ⅲ, the ureteral access sheath can be placed first to effectively eliminate the difficult angle and resistance of ureteroscopy caused by severe prostatic hyperplasia, and then semirigid ureteroscopic lithotripsy can be safely performed. It could avoid the treatment of benign prostatic hyperplasia at the same time or by stages.

Abstract
Objective: To investigate the related factors of thrombosis in patients with non-valvular atrial fibrillation (NVAF), and whether the combination of D-dimer, left atrial anteroposterior diameter and CHA2DS2-VASc score can be used to exclude left atrial thrombosis. Methods: A total of 75 NVAF patients with left atrial thrombosis confirmed by transesophageal echocardiography in Peking University People's Hospital from January 1, 2015 to December 31, 2019 were enrolled as the thrombus group. From January 1 to October 31, 2019, 80 patients with NVAF without left atrial thrombosis were enrolled as the control group. The clinical data, CHA2DS2-VASc score, hematological biomarkers, ultrasound data of two groups were compared. The independent factors associated with left atrial thrombosis were screened by univariate analysis and multivariate logistic regression analysis. The positive predictive value and negative predictive value for the diagnosis of left atrial thrombosis were gained by the score calculated based on the independent related factors. Results: There were no significant differences in age, gender, proportion of persistent atrial fibrillation and duration of atrial fibrillation between the two groups. The CHA2DS2-VASc score [M (Q1, Q3)] of the thrombus group was higher than that of the control group [2.5 (1.0, 3.0) vs 1.8 (1.0, 3.0), P=0.012]. The prothrombin time activity [M (Q1, Q3)] of the thrombus group was 81.1 (72.0, 93.0)%, which was lower than that of the control group 88.8 (83.0,96.0)% (P=0.008). The activated partial thromboplastin time (APTT) of the thrombus group was longer than that of the control group [(32.1±4.8) s vs (30.2±3.7) s, P=0.006]. D-dimer [M (Q1, Q3)] of the thrombus group was 231.0 (71.5, 272.2) ng/ml, which was higher than that of the control group 121.7 (49.0, 140.0) ng/ml (P<0.001). The left atrial anteroposterior diameter in thrombus group was larger [(44.6±6.6) mm vs (38.9±5.3) mm, P<0.001], the proportion of mitral regurgitation was higher (58.1% vs 26.8%, P<0.001). The left ventricular ejection fraction [M (Q1, Q3)] of the thrombus group was 56.7% (45.8%, 66.3%), which was lower than that of the control group 63.3% (60.5%, 70.2%) (P=0.003). Multivariate logistic regression analysis showed that the factor related to left atrial thrombosis was left atrial anteroposterior diameter (OR=4.480, 95%CI: 1.616-12.423). The negative predictive value of the new scoring system combined with D-dimer, left atrial anteroposterior diameter and CHA2DS2-VASc score for left atrial thrombosis was 100%. Conclusions: In NVAF patients, the factor independently associating with left atrial thrombosis is left atrial anteroposterior diameter. The combination of D-dimer, left atrial anteroposterior diameter, and CHA2DS2-VASc score can help exclude left atrial thrombosis before ablation of NVAF.

Abstract
Objective: To describe the epidemiological characteristics of COVID-19 outbreak in Gaocheng district of Shijiazhuan. Methods: Data and epidemiological survey reports of COVID-19 cases in the outbreak were collected from China's Infectious Disease Information System, Shijazhuang Municipal Center for Diseases Prevention and Control and official information published by the National Health Commission of China. The data were analyzed, using the descriptive epidemiological method. Results: From January 2nd to February 14th, 2021, a total of 1 033 laboratory confirmed COVID-19 cases were reported in Shijiazhuang. The attack rate was 9.36/100 000. The cases were distributed in 14 counties, and most cases (859/1 033, 83.16%) were reported in Gaocheng, and the disease spread to 5 provinces. The cases in Xiaoguo village (299 cases), Liujiazhuo village (107 cases) and Nanqiaozhai village (162 cases) of Zengcun township in Gaocheng accounted for 54.99% of the total cases in Shijiazhuang. The attack rates in the villages mentioned above were 7 412.00/100 000, 10 348.16/100 000 and 6 612.24/100 000, respectively. The ratio of urban cases to rural cases was 1∶15.53. The male to female ratio of the cases was 1∶1.34. The average age of the cases was 40.49 years. The incidence peaks occurred on January 3rd (9.97%, 103 cases) and on January 9th (9.10%, 94 cases). A total of 307 clusters occurred, in which 228(74.27%) occurred in households and 48 (15.64%) occurred in schools or child care settings. But the clusters related with church ceremony had the highest case numbers (82.67 cases/time), followed by wedding feast or feast celebrating the first month of newborn (28.29 cases/time). About 33.02% (313/948) of symptomatic cases only visited the village doctors or private clinics and had no medical care seeking history before the outbreak. Conclusions: The COVID-19 epidemic in Gaocheng of Shijiazhuang was a typical one in rural area. The rapid and hiding transmission of the outbreak was mainly due to the poor health service seeking of the rural residents and the frequent mass gathering.

Abstract
A study was conducted to investigate the inclusion effects of sugar beet pulp and rice straw mixture silage with inoculation (BRMS), in place of whole-plant corn silage (CS), on the dry matter intake, total-tract nutrient digestibility, plasma metabolites, rumen fermentation, and lactation performance in high-production dairy cows. Sixteen multiparous Holstein cows (body weight, 622 ± 35 kg; days in milk, 90 ± 11 d; mean ± standard deviation) were used in our experiments; the experiments were based on a repeated 4 × 4 Latin square design for 21 d, and each experimental period consisted of 14 d of adaptation, followed by 7 d of data collection. The 4 dietary treatments used were (dry matter basis): (1) 0% BRMS and 28.6% CS (0BRMS); (2) 4.3% BRMS and 24.3% CS (15BRMS); (3) 8.60% BRMS and 20.0% CS (30BRMS); and (4) 12.9% BRMS and 15.7% CS (45BRMS). The increasing inclusion of dietary BRMS was observed to linearly increase the total volatile fatty acids and the propionate concentration. The dry matter intake and digestibility values of neutral detergent fiber and acid detergent fiber increased linearly as the percentage of BRMS increased up to 45%. Milk yield linearly increased with the increase in the content of BRMS (39.0, 39.8, 40.9, and 40.3 kg/d for 0BRMS, 15BRMS, 30BRMS, and 45BRMS, respectively). The increasing inclusion of dietary BRMS induced a decrease in the ammonia nitrogen and milk urea nitrogen concentration, leading to a linear increase in milk protein production (1.15, 1.26, 1.35, and 1.27 kg/d for 0BRMS, 15BRMS, 30BRMS, and 45BRMS, respectively). In conclusion, the diets with the replacement of CS with BRMS up to 45% were beneficial to the production performance of high-production dairy cows, indicating that this method may be an appropriate use of sugar beet pulp and rice straw.

Abstract
Objective: To evaluate the efficiency of left cardiac sympathetic denervation (LCSD) in inherited arrhythmia patients with adrenergic activity-induced malignant ventricular arrhythmia, and observe exercise-stress test features before and after LCSD. Methods: This retrospective observational study included catecholaminergic polymorphic ventricular tachycardia(CPVT) and long QT syndromes(LQTS) patients who underwent video-assisted LCSD at Beijing Tsinghua Changgung Hospital and Peking University People's Hospital from September 2006 to May 2020. The indications for LCSD surgery were intolerant or refractory to beta-blocker medication. Clinical and exercise-stress tests data of included patients were collected before and 1 month after LCSD. Heart rate, exercise tolerance, atrial and ventricular arrhythmia, QTc interval and predictors for sudden cardiac death were analyzed. Patents were regularly followed up at 1, 3, 6, and 12 months after LCSD and then once every year thereafter. Cardiac events and medication adjustment records were collected. Results: Five patients (2 CPVT, 1 LQT1, and 2 LQT2)were included in the study. All patients experienced syncope as first symptom at the median age of 12(10, 16)years, and underwent LCSD at the median age of 21(16, 26)years, Baseline heart rate was similar before and after LCSD ((65.6±6.5) beats/min vs. (68.0±11.1) beats/min, P=0.57); while maximum workload tended to be lower after LCSD ((12.1±2.8) metabolic equivalents (METS) before surgery vs. (10.5±2.4) METS after surgery, P=0.07). Incidence of atrial and ventricular arrhythmia were significantly reduced post LCSD, and the ventricular arrhythmia score was decreased after LCSD in CPVT patients (4 points before LCSD vs. 3 points after LCSD in case 1;5 points before LCSD vs. 3 points after LCSD in case 2). QTc interval was shortened significantly in three LQTs patients (QTc interval at baseline heart rate: (546.6±72.3) ms before surgery vs. (493±61.1) ms after LCSD, P=0.047; QTc interval at maximal exercise heart rate: (516.3±73.7) ms before surgery vs. (486.7±64.2)ms after LCSD, P=0.035). Additionally, sudden cardiac death risk indicator ΔHRR1 (heart rate decreasing value within the first 1 min during recovery phase) decreased from (51.5±21.1) beats/min before surgery to (32.0±13.9) beats/min after surgery (P=0.035). During a median follow-up of 1(1, 4) year, all five patients were on low dosage of propranolol (37.0±21.7) mg/d. Cardiac events free survival was achieved in four out of 5 patients (80%) after sympathectomy, while 1 case suffered from sudden cardiac death after emotional stress. Conclusion: LCSD surgery can be safely and effectively performed in most hereditary arrhythmia patients with adrenergic activity-induced life-threatening cardiac events. Exercise stress test results show that LCSD could reduce malignant arrhythmias and improve sudden cardiac death risk indicators without decreasing heart rate.

Abstract
The measurement of the energy spectrum of cosmic ray helium nuclei from 70 GeV to 80 TeV using 4.5 years of data recorded by the Dark Matter Particle Explorer (DAMPE) is reported in this work. A hardening of the spectrum is observed at an energy of about 1.3 TeV, similar to previous observations. In addition, a spectral softening at about 34 TeV is revealed for the first time with large statistics and well controlled systematic uncertainties, with an overall significance of 4.3σ. The DAMPE spectral measurements of both cosmic protons and helium nuclei suggest a particle charge dependent softening energy, although with current uncertainties a dependence on the number of nucleons cannot be ruled out.

Abstract
Objective: To investigate the clinical efficacy of percutaneous vertebroplasty (PVP) combined with iodine-125 ((125)I) seed brachytherapy in the treatment of spinal metastatic epidural spinal cord compression (MESCC) and toassess the changes inthe grade of epidural spinal cord compression (ESCC) by magnetic resonance imaging (MRI). Methods: A total of 37 MESCC patients treated with PVP combined with (125)I seed brachytherapy in the interventional and vascular surgery department of Zhongda Hospital affiliated to Southeast University from January 2014 to June 2019 were retrospectively analyzed, including 23 cases of bilateral lower limbs paralysis. Total diseased vertebrae are 39 segments. Visual analogue scale (VAS) and paralysis of lower extremities were evaluated regularly before and after treatment, and VAS values at different follow-up time points were compared. At the same time, MRI was used to evaluate the changes of ESCC grade in the spinal canal and calculate the local lesion efficiency after operation. The postoperative local lesion efficiency at different follow-up times was compared. Results: PVP combined with (125)I seed implantation in all diseased vertebral bodies was successful. The average injection volume of polymethylmethacrylate (PMMA) was (3.2±1.3) ml/segment, the average number of (125)I seed implanted was (25.0±8.6) seeds/segment and the average radiation dose was (15.0±5.1) mCi/segment. The VAS before operation was 8.5, and postoperative VAS were respectively 3.6±1.3, 3.8±1.5, 3.4±1.4, 5.5±1.0, 5.9±1.4 at 5 days, 1 month, 3 months, 6 months, and 1 year after operation. The differences between all follow-up time points and preoperative VAS values were statistically significant (all P<0.001). Compared with 5 days, 1 month and 3 months after operation, VAS increased significantly at 6 months and 1 year after operation, and the difference was statistically significant (all P<0.001); there was no significant difference between the VAS value at 6 months after operation and 1 year after operation (P=0.405). At a follow-up of 3 months, 22 of 23 patients with paralysis of bilateral lower limbs regained the functions of autonomous walking and voiding; the effective rates of MESCC local lesions evaluated by MRI at 1 month, 3 months, 6 months, and>1 year were 89.7%, 91.9%, 90.6%, and 94.7%, respectively, and there was no statistically significant differences among those follow-up time points (all P>0.05). Conclusions: PVP combined with (125)I seed brachytherapy in the treatment of MESCC has significant improvement in immediate pain relief and spinal cord function. After combined treatment, MRI showed that the tumors around the spinal cord regressed dramatically, which could considerably reduce the MESCC grade and remain stable for a long time.

Abstract
OBJECTIVES To explore the associations of TNF-α -308 G>A (rs1800629) and TNF-β 252 A>G (rs909253) with physical function and plasma B-type natriuretic peptide (BNP). METHODS Data of 1747 community-dwelling elders from the ageing arm of the Rugao Longevity and Ageing Study was used. Physical function was measured by handgrip strength, Timed Up and Go (TUG) test and 5-meter walking test (5MWT). RESULTS AA genotype of the TNF-α -308 G>A was associated with higher mean time of TUG test and 5MWT (multivariable adjusted β=5.75 and 5.70, respectively, p<0.05), compared with GG genotype. For the TNF-β 252 A>G polymorphism, GG genotype was associated with higher mean time of TUG test and 5MWT (multivariable adjusted β=1.55 and 0.83, respectively, p<0.05) and lower handgrip strength (multivariable adjusted β=-0.69, p<0.05), compared with AA genotype. Further, GG was associated with greater odds of low handgrip strength (OR=1.47, 95% CI=1.06-2.04), low speed of TUG test (OR=1.87, 95% CI=1.20-2.01) and elevated BNP (OR=1.30, 95% CI=1.08-1.84). GG also interacted with elevated BNP to be associated with greater odds of low handgrip strength and 5MWT. CONCLUSIONS TNF-β 252 A>G was associated with physical function measurements, plasma BNP level, and odds of elevated BNP in an elderly population. TNF-β 252 A>G also interacted with elevated BNP to be associated with greater odds of physical function measurements.

Abstract
Objective: To assess the feasibility, safety, and efficacy of a novel fully covered radioactive stent for the treatment of advanced esophageal and gastric cardia cancer. Methods: Data of 122 patients, who underwent esophageal radioactive stent placement for advanced esophageal or gastric cardia cancer between January 2012 and September 2017 in Zhongda Hospital, were retrospectively analyzed. Patients were divided into the novel stent group (n=59; 45 males, 14 females; mean age 73±10 years old) and the conventional stent group (n=63; 51 males, 12 females; mean age 72±9 years old), according to the types of radioactive stents. No significant difference was found between the two groups in baseline characteristics (all P>0.05). Outcomes were measured in terms of technical success, dysphagia score, stent restenosis, stent migration, major complications, and overall survival. Results: The technical success rate was 98.3% in the novel stent group, and 100.0% in the conventional stent group (P=0.484) . The dysphagia scores 3 days after surgery decreased from 3.27±0.45 and 3.37±0.49 to 1.25±0.66 and 1.32±0.50, respectively (all P<0.01), and the variances were comparable (P=0.709). Compared with conventional stents, novel stents were significantly associated with a decreased in the rate of stent restenosis, 11.9% vs 27.0%; cause-specific hazard ratio 0.387, 95%CI 0.160-0.934 (P=0.035); sub-distributional hazard ratio 0.401, 95%CI 0.167-0.963 (P=0.041), while the stent migration rate was statistically comparable (13.6% vs 6.3%, P=0.181). There was no significant difference between the novel stent group and the conventional stent group in major complications (all P>0.05), including moderate-severe chest pain (22.0% vs 25.4%), hemorrhage (11.9% vs 11.1%), fistula formation (1.7% vs 4.8%), and aspiration pneumonia (5.1% vs 6.3%). The median overall survival was 146(95%CI 115-177) days in the novel stent group, and 147(95%CI 98-196) days in the conventional stent group, and no significant difference was found (P=0.967). Conclusions: In patients with advanced esophageal or gastric cardia cancer,placement of a novel fully covered radioactive stent is safe and effective. This novel stent can relieve dysphagia rapidly and prevent stent restenosis effectively.

Abstract
Objective: To investigate the expression of microRNA-1 (miR-1) and its regulatory function on fibronectin (FN) in human trabecular meshwork cells (HTMC) under oxidative stress. Methods: Experimental study. After HTMC were treated with 0, 60, 100, 200, 400 μmol/L hydrogen peroxide (H(2)O(2)) for 6 h, respectively, the cells were placed in culture medium for 24 h. The expression of miR-1 and FN mRNA in these cells were detected by real-time quantitative PCR. According to bioinformatics analysis, the target gene of miR-1 is predicted to be FN; pcDNA3/pri-miR-1 vectors, pcDNA3/enhanced green fluorescent protein (EGFP)-FN-3'UTR vectors and pcDNA3/EGFP-FN-3'UTRmut vectors were constructed. pcDNA3/pri-miR-1 were co-transfected with pcDNA3/EGFP-FN-3'UTR or pcDNA3/EGFP-FN-3'UTRmut respectively into HTMC. pDsRed2-N1 was taken as internal reference. After 48 h transfection, the absorbance of EGFP and red fluorescent protein (REP) was detected with fluorescence spectrophotometer to explore the effect of miR-1 on FN expression. HTMC was stimulated with 200 μmol/L H(2)O(2) for 24 h after overexpression plasmid of miR-1 was transfected into it, and then FN mRNA and protein levels were detected via real time PCR, Western blotting and immunofluorescence. Data were analyzed via one-way analysis of variance or t test. Results: With the increase of H(2)O(2) concentration, miR-1 decreased (F=390.80, P<0.01) while FN increased (F=13.16, P<0.01). The level of miR-1 in HTMC stimulated by 200 μmol/L and 400 μmol/L H(2)O(2) decreased to 0.608±0.014 (t=21.67, P<0.01) and 0.409±0.020 (t=29.91, P<0.01), respectively, compared with untreated control cells (1.000); whereas, the mRNA levels of FN increased to 1.630±0.233 (t=4.47, P=0.011) and 1.903±0.246 (t=6.15, P=0.003), respectively, compared with untreated control cells(1.000). Through bioinformatics analysis, miR-1 might have candidate binding site in FN mRNA 3'-UTR. Meanwhile, these cells co-transfected with pcDNA3/pri-miR-1 and pcDNA3/EGFP-FN-3'UTRmut (0.562±0.018) had higher EGFP expression than cells co-transfected with pcDNA3/pri-miR-1 and pcDNA3/EGFP-FN-3'UTR (0.329±0.015) (t=17.39, P<0.01). Compared with the control (1.000), after overexpressing miR-1 the mRNA expression and the protein level of FN decreased to 0.294±0.081 (t=11.01, P<0.01) and 0.584±0.022 (t=5.57, P<0.01), respectively. Conclusions: MiR-1 decreases while FN increased in HTMC under oxidative stress. MiR-1 inhibits FN expression through targeting FN 3'-UTR. (Chin J Ophthalmol, 2019, 55: 355-360).

Abstract
Debates regarding the most beneficial medical or surgical procedures for patients with spontaneous intracerebral hemorrhage (sICH) are still ongoing. We aimed to evaluate the risk of subsequent vascular disease and mortality in patients with sICH treated with and without surgical intervention, in a large-scale Asian population. Patients hospitalized within 2000 to 2013 who were newly diagnosed with sICH were identified using the National Health Insurance Research Database of Taiwan. Neuroendoscopy and craniotomy groups comprised patients who underwent surgical treatment within 1 week, while those in the control group did not undergo early surgical treatment. Outcomes included subsequent hemorrhagic and ischemic stroke, following acute myocardial infarction, congestive heart failure, and mortality. After propensity score matching, there were 663 patients in each group. Compared to that in the control group, the neuroendoscopy and craniotomy groups had a significantly higher risk of secondary vascular events at 1 to 3 months of follow-up (adjusted HR, 2.08 and 1.95; 95% CI, 1.21-3.58 and 1.13-3.35; p < 0.01 and p < 0.05, respectively), but a significantly lower risk after 3 years of follow-up (adjusted HR, 0.52 and 0.52; 95% CI, 0.35-0.78 and 0.35-0.77; p < 0.01 and p < 0.01, respectively). The mortality rate was higher in the craniotomy group at 6 to 12 months of follow-up (adjusted HR, 2.18; 95% CI, 1.06-4.49; p < 0.05) compared to that in the control group. Thus, a timely surgical intervention for hematoma evacuation is advantageous in preventing secondary vascular events and improving outcomes in the long term. However, greater attention to secondary ischemic stroke following the initial sICH episode is needed.

Abstract
Objective: To assess the feasibility and safety of endovascular denervation (EDN) with a multi-electrode radiofrequency ablation catheter on beagles. Methods: A total of 18 beagles, (10.2±1.1) kg,of either gender,were provided by the Animal Center of Southeast University (SYXK (Su) 2016-0013). They were divided equally into three groups:the instant euthanizing group, the long-term follow-up group and the sham operation group. Beagles in the instant euthanizing group were euthanized immediately after EDN. Beagles in the long-term follow-up group were euthanized three months after EDN. Beagles in the sham operation group underwent sham operation and were euthanized three months later. Blood biochemistry was measured at baseline, and immediately, 15 days, 30 days and 90 days after the surgery. Computerized tomographic (CT) angiography was determined before the surgery and 60 days after the surgery. Digital subtraction angiography (DSA) was determined 90 days after the surgery. Histopathologic analyses were used to identify the changes of arterial wall and neuron cells. Results: Beagles in the long-term follow-up group and the sham operation group all underwent EDN successfully without accidental death. No abdominal aortic perforation and peripheral tissue necrosis were found at Necropsy. No vascular injuries were found by CTA and DSA in each group. There was no statistical difference in hematological analyses, 90 days after the surgery:white blood cell:(12.5±1.5)×10(9)/L vs (13.2±0.7)×10(9)/L, P=0.275; red blood cell:(7.0±0.6)×10(9)/L vs (6.3±0.4)×10(9)/L, P=0.089; total bilirubin:(2.9±0.4) μmol/L vs (3.0±0.6) μmol/L, P=0.681; glutamic-pyruvic transaminase:(40±11) U/L vs (37±6) U/L, P=0.168; glutamic oxalocetie transaminase:(51±11) U/L vs (48±9) U/L, P=0.221; urea nitrogen:(7.2±1.2) mmol/L vs (6.9±0.8) mmol/L, P=0.505; creatinine:(60±9) μmol/L vs (59±9) μmol/L, P=0.81; prothrombin time:(7.2±0.7) s vs (7.0±0.7) s, P=0.719. Histopathological analyses showed that there were hypercellular appearance of nerve bundle and thickened perineurium in EDN groups, while normal perineurium around nerve bundle in the sham operation group. Conclusion: EDN could be applied in beagles safely and feasibly.

Abstract
Objective: To understand the trends on the epidemics of acute meningitis and encephalitis (AME) among children under 18 years-old in Shijiazhuang city, 2007-2017. Methods: Surveillance programs on acute meningitis and encephalitis (AMES) had been conducted in population less than 18 years-old, since 2007. Hospitals at county level or above in Shijiazhuang had been included to carry out the epidemiologic surveillance, including 6 on pathogens, regarding AMES. Qualitative description was performed to describe the epidemiologic patterns and pathogenic spectrums. Annual percent change (APC) was used to demonstrate the secular trends of AME. Results: In 2007-2017, 11 222 locally developed AME cases that younger than 18 years-old, were reported in Shijiazhuang, with the annual average incidence rate as 108.62/100 000 (1 021/939 974) and APC as 4.81%(95%CI: 3.90%-5.93%)(t=23.01, P<0.001). Age-specific incidence appeared the highest among 4-5 years-old (242.96 cases per 100 000 children per year). Significant differences were found among children of other aged years except aged 0- years (aged 1- years t=20.21, P=0.004; aged 2- years t=19.41, P=0.006; aged 3- years t=23.50, P<0.001; aged 4- years t=31.76, P<0.001; aged 5- years t=18.53, P=0.008; aged 10-17 years t=12.82, P=0.023). The ratio of male to female was 1.46 ∶ 1 (6 652/4 570). The ratio of urban to rural cases was 0.28 ∶ 1 (2 456/8 766). A total of 57.73% (6 478/11 222) of the cases were seen between June and September. The overall positive rate of pathogens was 20.07% (658/3 123) among these patients. The top five pathogens appeared as Enterovirus (44.68%, 264/658), Cryptococcus neoformans (9.12%, 60/658), Japanese encephalitis virus (8.66%, 57/658), Streptococcus pneumoniae (6.99%, 47/658) and Varicella-zoster virus (6.69%, 44/658). Conclusions: AME seriously harms the health of population under 18 years-old in Shijiazhuang city, with aged 3- years, aged 4- years in particular. Continued improvement on surveillance and expanded immunization are important to AME prevention and control.

Abstract
This study aimed to compare the differences in radiological outcomes and complications between single- and multilevel anterior cervical discectomy and fusion (ACDF) by using a polyetheretherketone (PEEK) cage-plate fusion system.Fifty-seven patients who underwent ACDF via the PEEK cage-plate fusion system were enrolled and subjected to ≥6 months of follow-up. The patients were divided into 4 groups according to different cage-plate implantation levels: 1-level group (n = 17), 2-level group (n = 24), 3-level group (n = 12), and 4-level group (n = 4). Fusion time, changes in segment and global lordotic angle, subsidence rate, and changes in disc and adjacent segmental disc height were subjected to radiological evaluation.The fusion period of multilevel ACDF was longer than that of single-level ACDF. The fusion period of the 3-level (4.09 ± 0.94, P = .004) and 4-level (5.25 ± 0.89, P = .004) group was also significantly longer than that of the 1-level group. The mean lordotic angle in all of the groups was changed in the immediate postoperative period and in the final follow-up. The cage subsidence rates were 11.76% (2/17) in the 1-level group, 20.83% (5/24) in the 2-level group, and 2/12 (16.67%) in the 3-level group. No subsidence occurred in the 4-level groups. Changes in the lower adjacent segmental disc height were significantly increased in multilevel ACDF compared with those in single-level ACDF.Despite the longer fusion time, the outcomes of the proposed system were even better with the greater number of treatment levels by using PEEK cage-plate fusion system. Changes in the lower adjacent segmental disc height should also prolong follow-up duration to investigate the symptomatic adjacent segment degeneration in multilevel ACDF.

Abstract
Objective: To evaluate the effectiveness of cement augmentation on the osteolytic lesion in patients with vertebral metastasis. Methods: A total of consecutive 132 patients with 268 vertebral metastatic lesions treated with PVP from January 2008 to December 2016 in Zhongda Hospital were enrolled in this study. Retrospective analysis of preoperative, postoperative 3 days, 3 months, 6 months, 12 months and ≥ 18 months imaging data on CT, the local control and progression of the tumor were evaluated by MDA response criteria. The local control rates were compared between the groups with the different rate of cement filling by Chi2-test. Results: Vertebroplasty procedures were performed successfully in all 268 vertebrae under DSA guidance, and the mean volume of PMMA injected in each vertebra was 0.7-8.5(3.9±1.5)ml.The rate of local control at 3 months, 6 months, 12 months and ≥18 months after PVP was respectively 98.9%, 95.1%, 91.8%, and 85.2%, the difference was statistically significant(all P<0.05). The local control rate showed a statistically significant relationship to the groups with the rate of cement filling at 6 months, 12 months and ≥18 months after PVP, but there was no statistical difference at postoperative 3 months. The rate of local control was higher in 68 patients with lung or gastrointestinal cancer than in 17 patients with liver or kidney cancer at 3 months, 6 months and 12 months, the difference was statistically significant (P<0.05). Conclusion: Cement augmentation has a local anti-tumor effect on vertebral osteolytic metastatic lesion, and the anti-tumor effect will decrease as the follow-up time extended.

Abstract
In this study of Th17/Treg cells, the therapeutic effect of Astragalus glycoprotein on collagen-induced arthritis in mice (CIA) was explored, and a basis for the clinical treatment of rheumatoid arthritis is provided. Sixty mice were selected for the establishment of a CIA mouse model, and were then randomly divided into a CIA model group, a hydrocortisone control group, a low, medium, and high dose group of Astragalus glycoprotein, respectively. The same number of control groups with same number of mice was established and after basic immunization, intraperitoneal injections were given once daily for two weeks in the treatment. At the end of the treatment, the mice in each group were selected and the proportion of Th17/Treg cells was detected by flow cytometry. The expression and positive expression of RORt, Foxp3, P-STAT3 and P-STAT5 protein were detected by Western blot and immunohistochemistry. Astragalus glycoprotein was shown to potentially improve the diet and mental state, reduce the arthritis index score and improve the pathological state of synovial membranes in the mice. Moreover, flow cytometry results showed that, compared with the CIA model group, the proportion of Th17 cells in the four other groups of mice decreased, while the proportion of Treg cells increased. This difference was statistically significant (P less than 0.05). From the experiment, the following conclusions were drawn: Astragalus glycoprotein can reduce Th17 cells and their transcription factors in the peripheral blood of CIA mice, up-regulate Treg cells and their transcription factors, and correct the balance of Th17/Treg cells so as to achieve an effective of treatment for CIA mice.

Abstract
Neurological deterioration of intracerebral hemorrhage (ICH) mostly occurs within the first 24 hours. Together with the microglia/macrophages (MMΦ), astrocytes are important cell population responsible for many brain injuries but rarely being highlighted in acute stage of ICH. In present study, we induced rats ICH either by collagenase or autologous blood injection. Experimental groups were classified as vehicle or Ethyl-1-(4-(2,3,3-trichloroacrylamide)phenyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate (Pyr3) treatment group (n = 9, each group). MRI assessments after ICH were used to evaluate the hematoma progression and blood-brain barrier (BBB) integrity. The glia cells accumulations were examined by GFAP and Iba1 immunohistochemistry, respectively. Abundant astrocytes but few MMΦ were observed in hyperacute and acute ICH. Upon suppression of astrocyte activity, ICH rats exhibited decreased size of hematoma expansion, less BBB destruction, reduced astrocyte accumulation in perihematomal regions, postponed course of hemoresolution and gain better outcomes. These finding provide evidence that activated astrocytes are crucial cell populations in hyperacute and acute ICH, and their modulation may offer opportunities for novel therapy and patient management.

Abstract
Objective: To assess the feasibility and safety of the irradiation stent system in portal vein on normal beagles. Methods: A portal vein irradiation stent system was composed of an Iodine-125 seeds-carrier and a conventional stent.Twenty beagle dogs were randomly assigned to receive treatment with a conventional stent (5 beagle dogs) or an irradiation stent system (15 beagle dogs in three groups received 11.1, 22.2, 33.3 MBq radioactivity, n=5 in each dose group). Follow-up methods included blood biochemical test, color Doppler sonographyand CT scan at 0, 15, 30, 60, and 120 days after implantation of irradiation stent system.Pathological tissues were obtained from sacrificed beagle dogs on the 120th day. Results: The portal vein irradiation stent systems and the conventional stents were successfully deployed into the targeted portal vein segment in all beagles, none was dislodged during the deployment or the follow-up period.Differences of blood biochemical indexes and portal vein flow volume measured by color Doppler sonography were not significant (P>0.05). Stent systems were morphologically intact and patent.None of the peripheral organs had hemorrhage, necrosis or perforation.Pathological tissues revealed that the systems were surrounded by fibrous tissues and a few inflammatory cells, but with no significant differences in all groups. Conclusion: It indicates that portal veinirradiation stent system is safe in all dose groups, and it is feasible to design a special irradiation stent system for each patient according to the size of the portal vein tumor thrombus.

Abstract
Objective: To explore the effects of varicocele on the expressions of inhibin B in rat testes and the relationship between expression of inhibin B and spermatogenesis dysfunction. Methods: Twenty specific-pathogen-free Sprague-Dawley (SD) male rats were randomly divided into two groups with random number table: 4-week control group (C4) and 4-week experimental group(V4). Experimental varicocele was created by partial ligation of left renal vein in the V4 group; vein isolation without ligation was performed in the C4 group.Spermatogenetic function in the two groups were assessed. The expression of inhibin B in the rat testis was analyzed by immunohistochemistry, the expressions of inhibin B, Fas and Fas ligand(FasL)mRNA measured by reverse transcription-polymerase chain reaction(RT-PCR), and the inhibin B protein expression by Western blot. Results: In comparison of spermatogenetic function in left rat testes, the Johnsen scores in the V4 group were significantly lower than those in the C4 group (9.79±0.05 vs 9.97±0.02, P=0.023), the seminiferous epithelium in the V4 group was significantly thinner than that in the C4 group [(48.35±0.99)μm vs (57.58±1.98)μm, P=0.000], and the number of sperms in the left epididymis was significantly lower than in the right one in the V4 group [(933±161)×106/(ml·g) vs(1 552±184)×106/(ml·g), P=0.017]. Both Western blot and immunohistochemical assay showed that the expression of inhibin B in the rat testes was significantly lower in the V4 group than in the C4 group(0.407±0.053 vs 0.608±0.076, P=0.038; 0.161±0.004 vs 0.183±0.005, P=0.008). RT-PCR also detected reduced expression of inhibin B mRNA in the V4 group compared with the C4 group(0.522±0.050 vs 1.106±0.210, P=0.003. Compared to the C4 group, the expression of Fas mRNA in the V4 group was significantly lower, while the expression of FasL mRNA in the V4 group was significantly higher(P=0.019, 0.015). Conclusions: Varicocele can lead to decreased expressions of inhibin B in rat testes and cause spermatogenesis dysfunction. There may be a close correlation between down-regulation ofinhibin B expression and spermatogenesis dysfunction.Inhibin B may play a significant rolein the mechanisms underlying male infertility due to varicocele.

Abstract
We investigated the role of two functional polymorphisms, IL-6-174G>C (rs1800795) and IL-6-572C>G (rs1800796), in the development of prostate cancer. A total of 212 consecutive primary prostate cancer patients and 236 control subjects were recruited between May 2012 and May 2014. The IL-6-174G>C (rs1800795) and IL-6-572C>G (rs1800796) polymorphisms were assessed by polymerase chain reaction-restriction fragment length polymorphism. The genotype distributions of IL-6-174G>C (rs1800795) and IL-6-572C>G (rs1800796) met the Hardy-Weinberg equilibrium in the controls. Unconditional logistic regression analyses showed that the GG genotype of IL-6-572C>G (rs1800796) was associated with an elevated risk of prostate cancer compared with the CC genotype, and the OR (95%CI) for the GG genotype was 2.06 (1.11-3.87). In conclusion, we suggest that the IL-6-572C>G (rs1800796) gene polymorphism influences the development of prostate cancer.

Abstract
Five lipid-producing yeast strains, CHC08, CHC11, CHC28, CHC34, and CHC35, were revealed by Sudan Black B staining to contain lipid droplets within cells. Molecular analysis demonstrated that they were 2 strains of Candida parapsilosis, Pseudozyma parantarctica, Pichia manshurica, and Pichia occidentalis. Following batch fermentation, P. parantarctica CHC28 was found to have the highest biomass concentration, total lipids and lipid content levels. The major fatty acids in the lipids of this yeast strain were C16 and C18. Predictions of the properties of yeast biodiesel using linear equations resulted in values similar to biodiesel made from plant oils. Preliminary production of yeast biodiesel from P. parantarctica CHC28 was accomplished through esterification and transesterification reactions. It was found that yeast lipids with high acid value are easily converted to biodiesel at an approximately 90% yield. Therefore, it is possible to use crude lipids as alternative raw materials for biodiesel production.

Abstract
We present a novel in situ reaction cell for heterogeneous catalysis monitored in situ by x-ray absorption spectroscopy (XAS) and resonant inelastic x-ray scattering (RIXS). The reaction can be carried out at a total pressure up to 1 atm, a regime that has not been accessible to comparable in situ techniques and thus closes the pressure gap to many industrial standard conditions. Two alternate catalyst geometries were tested: (A) a thin film evaporated directly onto an x-ray transparent membrane with a flowing reaction gas mixture behind it or (B) a powder placed behind both the membrane and a gap of flowing reaction gas mixture. To illustrate the working principle and feasibility of our reaction cell setup we have chosen ethylene epoxidation over a silver catalyst as a test case. The evolution of incorporated oxygen species was monitored by total electron/fluorescence yield O K-XAS as well as O K-RIXS, which is a powerful method to separate contributions from inequivalent sites. We find that our method can reliably detect transient species that exist during catalytic reaction conditions that are hardly accessible using other spectroscopic methods.

Abstract
BACKGROUND Osteoporosis is a significant public health issue worldwide. The underlying mechanism of osteoporosis is an imbalance between bone resorption and bone formation. However, the exact pathology is still unclear, and more related genes are on demand. AIM Here, we aim to identify the differentially expressed genes in osteoporosis patients and control. MATERIALS AND METHODS Biblio-MetReS, a tool to reconstruct gene and protein networks from automated literature analysis, was used for identifying potential interactions among target genes. Relevant signaling pathways were also identified through pathway enrichment analysis. RESULTS Our results showed that 56 differentially expressed genes were identified. Of them, STAT1, CXCL10, SOCS3, ADM, THBS1, SOD2, and ERG2 have been demonstrated involving in osteoporosis. Further, a bibliometric network was constructed between DEGs and other genes through the Biblio-MetReS. CONCLUSIONS The results showed that STAT1 could interact with CXCL10 through Toll-like receptor signaling pathway and Chemokine signaling pathway. STAT1 interacted with SOCS3 through JAK/STAT pathway.

Abstract
Cystic fibrosis (CF) transmembrane conductance regulator (CFTR) is expressed in the epithelial cells of a wide range of organs/tissues from which most cancers are derived. Although accumulating reports have indicated the association of cancer incidence with genetic variations in CFTR gene, the exact role of CFTR in cancer development and the possible underlying mechanism have not been elucidated. Here, we report that CFTR expression is significantly decreased in both prostate cancer cell lines and human prostate cancer tissue samples. Overexpression of CFTR in prostate cancer cell lines suppresses tumor progression (cell growth, adhesion and migration), whereas knockdown of CFTR leads to enhanced malignancies both in vitro and in vivo. In addition, we demonstrate that CFTR knockdown-enhanced cell proliferation, cell invasion and migration are significantly reversed by antibodies against either urokinase plasminogen activator (uPA) or uPA receptor (uPAR), which are known to be involved in various malignant traits of cancer development. More interestingly, overexpression of CFTR suppresses uPA by upregulating the recently described tumor suppressor microRNA-193b (miR-193b), and overexpression of pre-miR-193b significantly reverses CFTR knockdown-enhanced malignant phenotype and abrogates elevated uPA activity in prostate cancer cell line. Finally, we show that CFTR gene transfer results in significant tumor repression in prostate cancer xenografts in vivo. Taken together, the present study has demonstrated a previously undefined tumor-suppressing role of CFTR and its involvement in regulation of miR-193b in prostate cancer development.

Abstract
Larvae of many holometabolous insects possess abdominal appendages called prolegs. Lepidoptera larvae have prolegs in the segments A3-A6. Functions of Lepidoptera hox genes on these abdominal appendages development is still a controversial issue. In this article, we report the use of double strand RNA (dsRNA)-mediated interference (RNAi) to dissect the function of some hox genes, specifically E-complex genes Ubx, abd-A, and Abd-B, in the ventral appendage development of the Lepidoptera silkworm, Bombyx mori. We found that Ubx RNAi caused leg identity in A1 segment, abd-A RNAi caused severe defect of abdominal prolegs and Abd-B RNAi allowed proleg identity in more posterior abdominal segments. These results confirm that Lepidoptera hox genes Ubx and Abd-B have evolved the repressing function to ventral appendage development, which is similar to those of Drosophila. However, Lepidoptera abd-A might have been modified distinctively during evolution, and has important roles in directing the development of prolegs.

Abstract
AIMS To investigate the effect of tea polyphenol (TP) and Hanseniaspora uvarum alone or in combination against Botrytis cinerea in grapes and to evaluate the possible mechanisms involved. METHODS AND RESULTS TP alone was effective in controlling grey mould in grape at all concentrations. TP at 0.5 and 1.0% in combination with H. uvarum (1 x 10(6) CFU ml(-1)) showed a lower infection rate of grey mould. TP at 0.01% or above significantly inhibited the spore germination of B. cinerea. TP at 0.1% showed inhibition ability on mycelium growth of B. cinerea. The addition of TP did not affect the growth of H. uvarum in vitro and significantly increased the population of H. uvarum in vivo. CONCLUSIONS TP exhibited an inhibitory effect against B. cinerea and improved the biocontrol efficacy of H. uvarum. The inhibitory effects of spore germination and mycelial growth of B. cinerea and the increased populations of H. uvarum in vivo may be some of the important mechanisms of TP. SIGNIFICANCE AND IMPACT OF THE STUDY The results suggested that TP alone or in combination with biocontrol agents has great potential in the commercial management of postharvest diseases of fruits.

Abstract
Soil acidification is a major problem in soils of intensive Chinese agricultural systems. We used two nationwide surveys, paired comparisons in numerous individual sites, and several long-term monitoring-field data sets to evaluate changes in soil acidity. Soil pH declined significantly (P < 0.001) from the 1980s to the 2000s in the major Chinese crop-production areas. Processes related to nitrogen cycling released 20 to 221 kilomoles of hydrogen ion (H+) per hectare per year, and base cations uptake contributed a further 15 to 20 kilomoles of H+ per hectare per year to soil acidification in four widespread cropping systems. In comparison, acid deposition (0.4 to 2.0 kilomoles of H+ per hectare per year) made a small contribution to the acidification of agricultural soils across China.

AIMS To investigate the effect of tea polyphenol (TP) and Candida ernobii alone or in combination against postharvest disease (Diplodia natalensis) in citrus fruit and to evaluate the possible mechanisms involved. METHODS AND RESULTS TP at concentrations of 0.1%, 0.5% and 1.0% alone, or in combination with C. ernobii (1x10(6) CFU ml(-1)), showed a lower infection rate of stem-end rot. TP at the concentration of 0.5% or above significantly inhibited the spore germination of D. natalensis. TP at the concentration of 1.0% showed inhibitary ability on mycelium growth of D. natalensis. The addition of TP did not affect the growth of C. ernobii in vitro and significantly increased the population of C. ernobii in vivo. CONCLUSIONS TP exhibited an inhibitory effect against D. natalensis and improved the biocontrol efficacy of C. ernobii. It was direct because of the inhibitory effects of TP on spore germination and mycelial growth of D. natalensis in vitro and indirect because of the increased populations of C. ernobii in vivo. SIGNIFICANCE AND IMPACT OF THE STUDY The results suggested that TP alone or in combination with biocontrol agents has great potential in commercial management of postharvest diseases in fruits.

Abstract
Early life vaccination is necessary to protect young children from dental caries. Our group had previously reported that a plasmid DNA vaccine pGJA-P/VAX against the glucosyltransferase (GTF) enzyme and cell surface antigen AgI/II (PAc) of Streptococcus mutans (S. mutans) elicited a specific and protective immunity in adult experimental animal models. In this report, early life immunization with the same plasmid was studied following intranasal (i.n.) and intramuscular (i.m.) delivery in murine models. The potential of inducing mucosal and systemic immune responses to special antigens was measured by ELISA. In addition, cytokine production and protection effectiveness against dental caries formation were also investigated. In the i.n. route, rats were primed when they were 5 days old, and boosted after 10 and 20 days with either plasmid pGJA-P/VAX-bupivacaine complexes, or pGJA-P/VAX alone, or empty vector. The pGJA-P/VAX-bupivacaine combination was able to mount the immune responses characterized by increased antibody levels of specific salivary IgA and serum IgG, preferential IFN-gamma production and significant reduction in the dental caries lesions. In the i.m. route, rats were vaccinated with either pGJA-P/VAX alone or empty vector with the same immunization schedule as the i.n. route. Plasmid pGJA-P/VAX alone induced a significant increase in the serum IgG and IFN-gamma production. However, it was not effective in eliciting specific salivary IgA and in decreasing the dental caries formation. All these findings indicate the feasibility of immunity with a targeted fusion DNA vaccine to a young immune system.
