Abstract
Objective: To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China. Methods: This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis. Results: Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) (Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS (Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion: Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

Abstract
Carboxymethyl chitosan and resistant starch exhibit good performance in diabetes regulation. We prepared carboxymethyl chitosan - resistant starch complex. Test the properties of composite resistant starch by using X-ray diffraction, water contact angle, infrared spectroscopy, and scanning electron microscopy, interactions with intestinal microbiota and mouse experiments were also conducted. The results indicated that the composite resistant starch had a good effect on promoting the proliferation of probiotics on Bifidobacterium and a significant inhibitory effect on Escherichia coli than resistant starch (P < 0.05). After administration, the water intake and weight of diabetic mice were significantly reduced. The blood glucose of diabetic mice was also reduced, and oral glucose tolerance showed that the glucose degradation rates of composite resistant starch were significantly improved compared to model mice. Cholesterol, triglycerides, high-density lipoprotein and low-density lipoprotein were significantly lower than those in the diabetes group (P < 0.05). The diversity of the gut microbiota was also proven.

Abstract
Cadmium (Cd) is a common contaminant in aquatic environments. However, little is known about the mechanisms underlying Cd toxicity in the freshwater snail Cipangopaludina cathayensis (Heude, 1890). This study to investigate the toxic effects of Cd on the standard metabolism, antioxidant activities, immune function, and hepatopancreas transcriptome profiles of C. cathayensis. C. cathayensis was exposed to 0.25, 0.5, 1.0, or 1.5 mg/L Cd for 3 h, with results showing that Cd significantly inhibited oxygen consumption and ammonia excretion and disrupted the respiratory metabolism of C. cathayensis. In addition, the O:N ratio dropped below 7, indicating that C. cathayensis may rely exclusively on proteins as an energy source under Cd stress. To understand how Cd impacts the antioxidant activities, immune function, and transcriptional profiles, C. cathayensis were exposed to 0.5 (low exposure, L14) or 1.5 (high exposure, H14) mg/L Cd for 14 days. Our results indicate that Cd exposure leads to oxidative stress and immunosuppression, with the latter effect being larger for exposure to higher Cd concentrations. A total of 2172 differentially expressed genes (DEGs) were identified by transcriptome analysis of the hepatopancreas, of which 885 were upregulated and 1287 were downregulated. Gene ontology and KEGG analyses revealed that the DEGs in the H14 group are enriched for energy generation terms and the "oxidative phosphorylation" pathway, respectively. Therefore, up-regulation of energy metabolism may be an adaptive strategy under Cd stress. Moreover, several genes involved in antioxidant activity were downregulated, whereas genes related to reactive oxygen species generation were upregulated. In addition, many immunity-related genes were identified within the DEGs, indicating that Cd toxicity may affect immune defense. Further, DEGs in the H14 group were enriched for disease-associated pathways. Taken together, our results indicate that Cd exposure leads to metabolic disorders, oxidative stress, and immunosuppression and thus may potentially contribute to disease outbreaks.

Abstract
Dissolved organic carbon (DOC) plays a crucial role in the assessment of greenhouse gas emission and carbon balance in peatlands. However, limited research has been conducted on the seasonal variations and properties of soil water DOC content at different depths in the permafrost peatlands of the Great Hing'an Mountains. In this study, we analyzed the seasonal patterns of soil water DOC contents (surface, 10 cm, 20 cm, 30 cm, 40 cm, and permafrost layer) the permafrost peatlands of the Great Hing'an Mountains (Tuqiang Forestry Bureau), and investigated the influencing factors, such as electrical conductivity, dissolved oxygen, HCO3- concentration, pH value, oxidation-reduction potential, and CO2 content. The stability of DOC was assessed by using UV-Vis spectrum. There were significant seasonal dynamics of DOC content in soil water, with higher contents in autumn and lower content in summer, ranging from 55.7 to 188.1 mg·L-1. There were significant differences in DOC content among different soil depths, with the highest levels detected in the permafrost layer. The DOC content showed a significantly positive correlation with pH value and electrical conductivity, while showed a significantly negative correlation with redox potential, HCO3- concentration, and dissolved oxygen content. Additionally, there was a significantly positive correlation between DOC and CO2 contents. The dissolved CO2 content in soil water increased with soil depth, with the highest content observed in the permafrost layer. Results of spectral analysis showed higher aromaticity in autumn compared to summer, indicating greater stability of DOC during the autumn season. Our results clarified the seasonal variations of soil water DOC in permafrost peatlands of the Great Hing'an Mountains and could provide important data to understand the carbon cycling in the region.

Abstract
Transition metal coordination complexes have provided cancer treatment with new insights to overcome the limitations of current chemotherapeutic agents. Utilization of bifunctional tetrazole-carboxylate ligands with Zn(ii) obtained two self-assembled complexes [Zn(HL1)(bipy)3/2(H2O)]·CH3OH·4(H2O) (1) (H3L1 = 1,3,5-tri(2-carboxymethyltetrazol-5-yl) benzene) and [Zn(L2)2(H2O)2]2·2H2O (2) (HL2 = (5-pyridin-3-yl-tetrazol-2-yl)-acetic acid). The X-ray diffraction results showed that the two complexes displayed a two-dimensional (2D) layer structure and a one-dimensional (1D) layer structure. Nanocoprecipitation with DSPE-PEG-2000 resulted in the formation of complex nanoparticles (NPS) with excellent water dispersion. In vitro CCK-8 assay indicated the two NPs exert high cytotoxicity and sensitivity and a low half-maximum inhibitory concentration (IC50) towards HeLa than HepG2 cells. In addition, the cytotoxicity was also confirmed by live/dead co-stained experiments. The presented experimental results showed the 1 and 2 NPs were capable of inhibiting cell proliferation in vitro and may help design coordination complex-based anticancer candidates for cancer cells.

Abstract
Green agriculture has become the "wind vane" of agricultural reform in the new era. The development concept of Chinese materia medica(CMM) ecological agriculture and the emergence of new technologies provide momentum for the supply of high-quality green ecological products. As special ecological products, Dao-di herbs have medicinal, economic, ecological, and cultural values. The ecological planting of CMM and the value realization of ecological products are of great significance for the high-quality development of CMM agriculture and for prospering agriculture by improving quality. Therefore, this paper reviews the development status and typical cases, and puts forward the advantages of ecological product value realization of Dao-di herbs. On this basis, a value accounting system for ecological products of CMM was constructed from three aspects: supply services, ecological services, and cultural services. Finally, the suggestions for realizing the value of CMM ecological products are put forward.(1)It is suggested to strengthen the practice of ecological planting and production of CMM, and innovate the value realization model of ecological products.(2)The ecological planting bases of Dao-di herbs should be constructed to enhance the supply capacity of high-quality ecological products.(3)The quality and safety of ecological CMM should be improved to create the ecological planting brand of Dao-di herbs.(4)The ecological product value system and mechanism should be improved for realizing the value of CMM ecological products.(5)The education and publicity should be strengthened to raise the public awareness of the value of CMM ecological products.

Abstract
This study aims to explore the soil fertility in the main Artemisia argyi planting areas in Qichun county.To be specific, the soil physical and chemical properties in the main planting areas of A.argyi in Qichun county were analyzed.On this basis, 12 indexes were selected for principal component analysis(PCA) which was then combined with the norm value of each index and the correlation coefficients between the indexes to establish the minimum data set(MDS).The radar map was plotted to directly demonstrate the level of each index and the comprehensive level of the sampling sites.The comprehensive index model was used to calculate the soil fertility quality index(SFQI) of the total data set(TDS) and MDS(SFQI-TDS and SFQI-MDS, respectively), and linear regression of the two was performed.The results showed that the indexes that made up the MDS for soil fertility evaluation were pH, available potas-sium, available iron, available zinc, available manganese, available copper, and available magnesium.The radar map suggested the greatest difference in soil organic matter and smallest difference in available nitrogen among the 14 sampling sites.Moreover, the overall content of available phosphorus and available iron was high, while that of available nitrogen was the lowest.The SFQI-MDS which was yielded based on the weight of each index in MDS calculated with the norm value was more sensitive and the SFQI had stronger correlation with TDS-SFQI, which can better represent TDS-SFQI.SFQI-MDS was in the range of 0.298-0.784, with the average of 0.565 and variation coefficient of 18.38%.Caohe Town had the highest average SFQI-MDS.Clustering of SFQI-MDS value suggested that the soil fertility can be classified into 4 levels: level Ⅰ(SFQI ≥ 0.677) indicated excellent soil fertility, which accounted for 11.24%(mainly in Qingshi town, Balihu, and Zhangbang town); level Ⅱ(0.571≤SFQI≤0.680) meant good fertility, which made up 43.82%(mainly in Caohe town, Hengche town, and Pengsi town); level Ⅲ(0.466≤SFQI≤0.557) indicated average fertility, which took up 32.58%(mainly in Chidong town and Zhulin town); level Ⅳ(SFQI≤0.421) suggested poor fertility, which accounted for 12.36%(mainly in Guanyao town).It is recommended that nitrogen, potassium, magnesium, and calcium fertilizers should be increased and organic ferti-lizer should be applied for the cultivation of A.argyi in Qichun county to improve soil fertility and soil physical and chemical properties.

Abstract
Gastrodia elata, as the valuable Chinese medicinal material, has been used for more than 2 000 years in China. With the increasing market demand for G. elata, the traditional wild resources have been unable to transform into commodities. At present, local authorities give full play to the advantages of natural resources and vigorously cultivate G. elata to form the cultivation mode and technical system with local characteristics. Huanggang Comprehensive Experimental Station of National Technical System of Chinese Medicinal Materials Industry has optimized and summarized the paddy-upland rotation of G. elata-Oryza sativa in Dabie Mountains of Hubei province through field visits and guidance for four consecutive years. Based on the ecological adaptability and planting characteristics of G. elata and O. sativa, and the actual production experience of farmers, analyzed the principle of paddy-upland rotation from production environment selection and fungus treatment, and evaluated the paddy-upland rotation of G. elata-O. sativa from production status, ecological benefits, and economic benefits. The paddy-upland rotation of G. elata-O. sativa has achieved efficient cultivation of G. elata and produced considerable economic benefits. Through the summary, analysis, and evaluation of the paddy-upland rotation mode of G. elata-O. sativa in Dabie Mountains, the present study put forward the optimization strategy of cultivation technology for G. elata in low-altitude areas, i.e., to use artificial Armillaria sticks instead of traditional cut-log for substitute cultivation of G. elata, which can effectively alleviate the "bacteria-forest contradiction" arising from the cultivation of G. elata. It can also improve the ecological environment and production status of the Dabie Mountains and even the G. elata producing areas at the same altitude.

Abstract
Trigeminal schwannomas are rare tumours comprising 0.2% of all intracranial tumours and 0.5% of all head and neck tumours. Patients with trigeminal schwannomas presented with facial hypoesthesia and pain. We presented a case with left bulging oropharynx. The CT scan showed a 3.8x2.6x4.9cm left parapharyngeal tumour compressed to the oropharynx and middle cranial fossa. We performed 3 ways in two times of operation to excise the whole tumour. We chose the transoral approach for parapharyngeal space, trans-parotid approach for deep parotid part and the endoscopic endonasal trans-pterygoid approach and trans-maxillary with Canine fossa trephination for intracranial lesions. The pathology showed schwannoma. A huge schwannoma extended from intracranial to several spaces is difficult to resect just by one approach. We should separate the tumour to several parts by clinical image before the operation and design a plan to remove the whole tumour in different approach. The different space of tumour involvement had several ways to access. We needed to choose the less harm but with better surgical field.

Abstract
Objective To investigate the characteristics of response inhibition of overweight/obese people, using behavior experiments combine with neural electrophysiological technology and discussing the difference in impulse level between obesity/overweight and normal-weight people through EEG data, questionnaire, and behavior experiment. Method (1) All participants completed the Go/Nogo task; meanwhile, behavior data and 64 channel EEG data were recorded. (2) Participants completed the Stop-Signal task and behavior date was recorded. Results (1) During Go/Nogo task, no significant differences were found in reaction time, omission errors of the Go task between the two groups, while commission errors of the Nogo task of the control group were significantly greater than the overweight/obesity group. (2) About SSRT during the Stop-Signal Task, the interaction of stimulus type (high-calorie food picture, low-calorie food picture) and group (control group, overweight/obesity group) was significant (p = 0.008). (3) No significant differences were found between the two groups in amplitude and latency of N2. About the amplitude of P3, the interaction of task type (Go task, Nogo task), electrode point (Cz, CPz, Pz), and groups were significant (p = 0.041), the control group P3 amplitude was significantly greater than overweight/obesity group during the Nogo task. Regarding about latency of P3, the interaction of group and electrode point were not significant (p = 0.582), but the main effect of task type was significant (p = 0.002). Conclusion (1) In terms of behavioral outcomes, overweight-obese subjects had lower dominant response inhibition and response cessation compared to normal-weight subjects. (2) In terms of EEG results, overweight-obese subjects showed no difference in processing speed and level of conflict monitoring for early inhibitory processing compared to normal-weight subjects, but there was a deficit in behavioral control for late inhibitory processing.

Abstract
Carbon dioxide peaking and carbon neutrality have become hot issues of political and economic activities in China and abroad. The structure and development of various industries in China will be profoundly affected in the process of accomplishing "Dual Carbon" goals. Eco-agriculture of Chinese medicine(EACM) highlights the balance and sustainable development of the ecosystem while producing high-quality medicinal materials. With chemically synthesized fertilizers, pesticides, and growth regulators prohibited, EACM emphasizes the recycling of agricultural and sideline products and the reduction of waste output, which results in the minimal negative impact on the ecological environment. Therefore, it is typical agriculture with low-carbon sources and high-carbon sinks. This study reviewed the mechanism and potential of EACM in carbon dioxide peaking and carbon neutrality, analyzed the specific ways of EACM in reducing carbon sources and increasing carbon sinks based on the typical ecological planting pattern, and proposed the point of view to strengthen EACM as well as the "Dual Carbon" theory and research methods, so as to direct low-carbon and efficient deve-lopment. Furthermore, this study advocated to comprehensively promote the transformation of Chinese medicine production from chemical agriculture to eco-agriculture to improve the comprehensive benefits of contribution rate of carbon neutrality, explore and establish carbon sink compensation mechanism to ensure the sustainable and healthy development of EACM, and strengthen the training of EACM and "Dual Carbon" theory and technologies to continuously improve the capacity of EACM in sustainable development. This study is expected to provide a reference for the development of ecological functions in EACM and the development of economic functions through ecological functions.

Abstract
Ovarian cancer (OC) is a common gynecological malignant tumor that seriously endangers the health of women worldwide. Tripartite motif containing 29 (TRIM29) is a TRIM family member that is frequently overexpressed in OC. However, the specific role of TRIM29 in OC remains obscure. To investigate the underlying molecular mechanism, a global proteomics analysis identified SET binding protein 1 (SETBP1) as a crucial target of TRIM29. Subsequently, the SETBP1/SET/Protein phosphatase 2 (PP2A) axis was confirmed to be required for the recovery of cancer stem cell (CSC)-like phenotype suppressed by TRIM29 knockdown. Mechanistically, TRIM29 facilitated SETBP1 transcriptional activation via the VEZF1 transcription factor. More importantly, TRIM29 promoted VEZF1 mRNA translation by recruiting RNA binding protein BICC1 to its 3'UTR. The clinical significance was established by the association of TRIM29 and SETBP1 expression with clinicopathological features in OC samples. The SETBP1/SET/PP2A axis driven by TRIM29 via transcription factor VEZF1 is at least one of the primary mechanisms underlying TRIM29 maintenance of the CSC-like characteristics in OC.

Abstract
Ovarian cancer is the most lethal gynecologic malignant cancer, frequently due to its late diagnosis and high recurrence. Cancer stem cells (CSCs) from different malignancies including ovarian cancer have been linked to chemotherapy resistance and poor prognosis. Therefore, identifying the molecular mechanisms mediating therapy resistance is urgent to finding novel targets for therapy-resistant tumors. Aberrant O-glycosylation ascribed to subtle alteration of GALNT family members during malignant transformation facilitate metastasis in various cancers. The current study demonstrated that BAG3 was upregulated in platin-resistant ovarian cancer tissues and cells, and high BAG3 predicted dismal disease-free survival of patients with ovarian cancer. In addition, the current study showed that BAG3 facilitated CSC-like properties of ovarian cancer cells via regulation of GALTN10. In a term of mechanism, BAG3 epigenetically regulated GALNT10 transactivation via histone H3 lysine 4 (H3K4) presenter WDR5. We demonstrated that WDR5 increased H3K4 trimethylation (H3K4me3) modification at the promoter regions of GALNT10, facilitating recruitment of transcription factor ZBTB2 to the GALNT10 promoter. Collectively, our study uncovers an epigenetic upregulation of GALNT10 by BAG3 via WDR5 to facilitate CSCs of platin-resistant ovarian cancers, providing additional information for further identification of attractive targets with therapeutic significance in platin-resistant ovarian cancer.

Abstract
The pathogenesis of papillary thyroid cancer (PTC), the most common type of thyroid cancer, is not yet fully understood. This limits the therapeutic options for approximately 7% of invasive PTC patients. The critical role of AUF1 in the progression of thyroid cancer was first reported in 2009, however, its molecular mechanism remained unclear. Our study used CRISPR/Cas 9 system to knockdown AUF1 in IHH4 and TPC1 cells. We noticed that the expression of TRIM58 and ZBTB2 were increased in the AUF1 knockdown IHH4 and TPC1 cells. When TRIM58 and ZBTB2 were inhibited by small hairpin RNAs (shRNAs) against TRIM58 (shTRIM58) and ZBTB2 (shZBTB2), respectively, the proliferation, migration, and invasion ability of the AUF1-knockdown IHH4 and TPC1 cells were increased. In addition, two ZBTB2 binding sites (-719~-709 and -677~-668) on TRIM58 promoter and two AUF1 binding sites (1250-1256 and 1258-1265) on ZBTB2 3’-UTR were identified. These results suggested that AUF1 affecting thyroid cancer cells via regulating the expression of ZBTB2 and TRIM58.

Abstract
Ovarian cancer is the most frequent cause of gynecologic malignancies associated death. Primary or acquired cisplatin resistance is frequently occurred during ovarian cancer therapy. Cancer stem cells (CSC) tend to form minimal residual disease after chemotherapy and are implicated in relapse. The ability of cancer cells to reprogram their metabolism has recently been related with maintenance of CSC and resistance to chemotherapies. The current study found that BAG5 expression was decreased in cisplatin-resistant ovarian cancer cells and clinical tissues. Our data demonstrated that BAG5 knockdown was implicated in metabolic reprogramming and maintenance of cancer stem cell (CSC)-like features of ovarian cancer cells via regulation of Rictor and subsequent mTORC2 signaling pathway. In addition, the current study demonstrated that Bcl6 upregulation was responsible for repression of BAG5 transactivation via recruitment on the BAG5 promoter in cisplatin-resistant ovarian cancer. The current study also demonstrated reverse correlations between BAG5 and Bcl6, BAG5 and Rictor in ovarian serous adenocarcinoma tissues. Collectively, the current study identified the implication of Bcl6/BAG5/Rictor-mTORC2 signaling pathway in metabolic reprograming and maintenance of CSC-like features in cisplatin-resistant ovarian cancer cells. Therefore, further studies on the mechanism underlying regulation of metabolic reprogramming and CSC-like characteristics of cisplatin-resistant ovarian cancer cells may contribute to the establishment of novel therapeutic strategy for cisplatin-resistance.

Abstract
As the most advanced environment-friendly production model in the international society, ecological agriculture of Chinese materia medica(CMM) is the only way for the development of modern agriculture. With the proposal of the declaration on ecolo-gical agriculture of CMM, "Don't grab land from farmland, don't be enemies of grass and insects, don't be afraid of barren slopes and forests, and live up to the green and green mountains", the ecological planting of CMM has blossomed all over the country, and formed a scientific theory, technology and model. Based on the theory and method of economics, this paper expounds the comprehensive benefits and development advantages of ecological agriculture of CMM from the perspectives of farmers(producers), patients(consumers) and the country. From the perspective of medicinal farmers, the input and output income of conventional agriculture and ecological agriculture of CMM such as Panax ginseng, Astragalus propinquus, Atractylodes lancea, and Bupleurum chinense were compared, and it was found that ecological agriculture of CMM had obvious advantages in net income, average annual income and input-output ratio, which could better promote farmers' income. From the perspective of patients, according to the same dose, the content of active ingredients in ecologically planted CMMs is significantly higher than that in conventionally-planted herbs, and the amount of effective substances taken by patients is also higher, so as to achieve better therapeutic effect. At the national level, ecological planting of CMM is the key to ensuring the high-quality development of CMM industry, increasing farmers' income, ensuring the safety of people's drug use and promoting the sustainable development of agriculture. It is also an important part of realizing the harmonious development of economy, society and environment and promoting ecological civilization. In general, the declaration on ecological agriculture of CMM embo-dies the core characteristics and goals of ecological agriculture, and also points of the path and vision of ecological agriculture of CMM in the future. The declaration will guide production practice, promote the benefit of farmers, and lay the foundation for the sustainable development of CMM industry.

Abstract
HYOU1 is upregulated in many kinds of cancer cells, and its high expression is associated with tumour invasiveness and poor prognosis. However, the role of HYOU1 in papillary thyroid cancer (PTC) development and progression remains to be elucidated. Here, we reported that HYOU1 was highly expressed in human PTC and associated with poor prognosis. HYOU1 silencing suppressed the proliferation, migration and invasion of PTC cells. Mechanistic analyses showed that HYOU1 silencing promoted oxidative phosphorylation while inhibited aerobic glycolysis via downregulating LDHB at the posttranscriptional level. We further confirmed that the 3'UTR of LDHB mRNA is the indirect target of HYOU1 silencing and HYOU1 silencing increased miR‐375‐3p levels. While LDHB overexpression significantly suppressed the inhibitory effects of HYOU1 silencing on aerobic glycolysis, proliferation, migration and invasion in PTC cells. Taken together, our findings suggest that HYOU1 promotes glycolysis and malignant progression in PTC cells via upregulating LDHB expression, providing a potential target for developing novel anticancer agents.

Abstract
TRIM29 is dysregulated in pancreatic cancer and implicated in maintenance of stem-cell-like characters of pancreatic cancer cells. However, the exact mechanisms underlying oncogenic function of TRIM29 in pancreatic cancer cells remain largely unclarified. Using a global screening procedure, the current study found that adenylate kinase 4 (AK4) was profoundly reduced by TRIM29 knockdown. In addition, our data demonstrated that TRIM29 knockdown altered bioenergetics and suppressed proliferation and invasion of pancreatic cancer cells via downregulation of AK4 at the posttranscriptional level. The current study demonstrated that upregulation of microRNA-2355-3p (miR-2355-3p) upregulated AK4 expression via facilitating DDX3X recruitment to the AK4 transcript, and TRIM29 knockdown thereby destabilized the AK4 transcript via miR-2355-3p downregulation. Collectively, our study uncovers posttranscriptional stabilization of the AK4 transcript by miR-2355-3p interaction to facilitate DDX3X recruitment. Regulation of AK4 by TRIM29 via miR-2355-3p thereby provides additional information for further identification of attractive targets for therapy with pancreatic cancer.

Abstract
OBJECTIVE To investigate the epidemiological characteristics of malaria and implementation of the "1-3-7" approach in malaria elimination in Yunnan Province, so as to provide the data support for the development of post-elimination surveillance interventions. METHODS All data pertaining to malaria cases in Yunnan Province from 2014 to 2019 were captured from the Notifiable Disease Reporting System of Chinese Center for Disease Control and Prevention, and the changes in the epidemic situation of malaria were analyzed during the 5-year period. In addition, the core indexes regarding the "1-3-7" approach in malaria elimination of Yunnan Province from 2014 to 2019 were retrieved from the Malaria Control System in the Parasitic Disease Information Reporting System, and all changes in the indexes were descriptively analyzed. RESULTS During the period from 2014 to 2019, a total of 2 283 malaria cases were reported in Yunnan Province, including 1 927 cases with vivax malaria, 326 cases with plasmodium malaria, 29 cases with other species of malaria, and one case with unidentified species. There were 64 local cases, 2 219 overseas imported cases. Among the 2 283 malaria cases, the male/female ratio was 4.58∶1, and 80.25% of the cases were aged from 15 to 50 years. Farmer (70.00%) was the predominant occupation, and 76.70% (1 751/2 283) of the cases were identified in 25 border counties (districts). Malaria cases were reported in each month during the 5-year period, and the number of malaria cases increased from April, peaked on May to July, and started to decline on August. From 2014 to 2019, the reporting rate of malaria cases within 24 hours upon diagnosis was 100%, and the detection of malaria cases was 99.69% (2 276/ 2 283) in the laboratory, with a 99.65% (2 275/2 283) rate of definite diagnosis. In addition, the percentage of individual epidemiological investigations within 3 days was 100.00% (2 283/2 283), and the number of epidemic foci survey and treatment within 7 days was 576 during the 3-year period from 2017 to 2019. The goal of malaria elimination was achieved in Yunnan Province on June, 2020. CONCLUSIONS Malaria has been eliminated in Yunnan Province, and management of overseas imported malaria is the primary challenge to consolidate the malaria elimination achievements in the future. However, the approach in malaria elimination remains to be maintained, and the role of the Yunnan Provincial Malaria Diagnostic Reference Laboratory requires to be strengthened.

Abstract
Ovarian cancer is the deadliest gynaecologic malignancy, and the five-year survival rate of patients is less than 35% worldwide. Cancer stem cells (CSCs) are a population of cells with stem-like characteristics that are thought to cause chemoresistance and recurrence. TRIM29 is aberrantly expressed in various cancers and associated with cancer development and progression. Previous studies showed that the upregulation of TRIM29 expression in pancreatic cancer is related to stem-like characteristics. However, the role of TRIM29 in ovarian cancer is poorly understood. In this study, we found that TRIM29 expression was increased at the translational level in both the cisplatin-resistant ovarian cancer cells and clinical tissues. Increased TRIM29 expression was associated with a poor prognosis of patients with ovarian cancer. In addition, TRIM29 could enhance the CSC-like characteristics of the cisplatin-resistant ovarian cancer cells. Recruitment of YTHDF1 to m6A-modified TRIM29 was involved in promoting TRIM29 translation in the cisplatin-resistant ovarian cancer cells. Knockdown of YTHDF1 suppressed the CSC-like characteristics of the cisplatin-resistant ovarian cancer cells, which could be rescued by ectopic expression of TRIM29. This study suggests TRIM29 may act as an oncogene to promote the CSC-like features of cisplatin-resistant ovarian cancer in an m6A-YTHDF1-dependent manner. Due to the roles of TRIM29 and YTHDF1 in the promotion of CSC-like features, they may become potential therapeutic targets to combat the recurrence of ovarian cancer.

Abstract
Papillary thyroid cancer (PTC) is the most common endocrine tumor with an increasing incidence, has a strong propensity for neck lymph node metastasis. Limited treatment options are available for patients with advanced or recurrent metastatic disease, resulting in a poor prognosis. Tripartite motif protein 29 (TRIM29) is dysregulated in various cancer and functions as oncogene or tumor suppressor in discrete cancers. In this study, we found that both TRIM29 and fibronectin 1 (FN1) were upregulated with positive correlation in PTC tissues. Neither overexpression nor downregulation of TRIM29 altered the proliferation of PTC cells significantly. Overexpression of TRIM29 significantly promotes, while knockdown of TRIM29 significantly decreases migration and invasion by regulating FN1 expression in PTC cells. In terms of mechanism, we found that TRIM29 altered the stability of FN1 mRNA via regulation of miR-873-5p expression. The current study also demonstrated that long non-coding RNA (LncRNA) CYTOR suppressed maturation of miR-873-5p via interaction with premiR-873, and TRIM29 decreased miR-873-5p via upregulation of CYTOR. This study suggests that involvement of TRIM29 in migration and invasion in PTC cells may reveal potential metastatic mechanism of PTC and represent a novel therapeutic target and strategy.

Abstract
Numerous studies showed that the growth of medicinal plants in their native areas was simultaneously affected by abiotic stress combinations. Compared with single stress, plants have unique responses to a combination of different abiotic stresses and cannot be inferred directly from plants' responses to each individual stress. The effect of combined stresses on plants usually has three types of synergistic antagonism or independence. The secondary metabolism in the process of medicinal plant stress combination response also played a vital role, and environmental stresses can spur the accumulation of secondary metabolites, but under the stress combination, plants induce specific gene expression of key enzymes on secondary metabolic pathways, in turn, the accumulation of secondary metabolites against stress is formed. When plants are subjected to stress combination, the interaction of multiple signaling pathways makes it highly complex for plants to respond to stress combination. This paper summarized the effects of stress combination on physiological and secondary metabolism of medicinal plants, and discussed the related physiological, biochemical and molecular mechanisms. It provides theoretical basis for improving the adaptability of medicinal plants to adversity, improving the quality of Chinese medicinal materials, and further optimizing the cultivation of medicinal plants.

Abstract
Objective: To evaluate the clinical characteristics and diagnostic strategies of early hydatidiform mole. Methods: A retrospective cohort study was conducted of 526 women with hydatidiform mole who underwent suction curettage and were confirmed by histopathology in Dalian Maternal and ChildHealth Care Hospital from Feb. 2013 to Feb. 2018, including 484 women with gestational age less than or equal to 12 weeks (the early group) and 42 women with gestational age greater than 12 weeks (the late group). The clinical characteristics between the two groups were compared, and the pathological diagnosis and pre-evacuation ultrasound examination of the early group were further discussed. Results: Compared with the late group, the clinical characteristics of the early group tended to be atypical, and the incidence of vaginal bleeding, excessive uterine size, theca lutein cysts (>6 cm) and pregnancy complications decreased significantly (all P<0.05). The serum level of β-hCG in the early group was significantly lower than that in the late group (Z=-2.382, P=0.017). While there was no significant difference in the pre-evacuation ultrasound detection rate between the two groups (53.5% vs 66.7%; χ(2)=2.697, P=0.101). Five hundred and fifteen patients completed the follow-up, and 38 patients with post-mole neoplasia were all cured. There was no significant difference in the malignant transformation rate of hydatidiform mole between the two groups (7.0% vs 11.9%; χ(2)=0.745, P=0.388). In the early group, 302 cases of complete hydatidiform mole (CHM), 179 cases of partial hydatidiform mole (PHM) and 3 cases of unclassified hydatidiform mole (UHM) were histologically diagnosed, according to pathological morphology combined with p57(KIP2) immunohistochemical staining. Compared with pathological diagnosis, the overall pre-evacuation ultrasound detection rate in the early hydatidiform mole was 53.5% (259/484), which was significantly better for complete (78.1%, 236/302) versus partial (11.7%, 21/179) hydatidiform moles (χ(2)=199.224, P<0.01). There was significantly weak negative correlation between the overall ultrasound detection rate and gestational age of hydatidiform mole (r=-0.211, P<0.01). The gestational age of early PHM was significantly longer than that of CHM (68.0 vs 58.5 days; Z=-8.048, P<0.01). Conclusions: The clinical presentations of early hydatidiform mole are not typical. Although ultrasound examination identifies only about half of hydatidiform moles, ultrasonography is still an important auxiliary examination method. Morphological examination combined with p57(K)IP2 immunohistochemical staining could effectively diagnose early hydatidiform mole, so as to reduce the missed diagnosis of hydatidiform mole.

Abstract
Solid tumour frequently undergoes metabolic stress during tumour development because of inadequate blood supply and the high nutrient expenditure. p53 is activated by glucose limitation and maintains cell survival via triggering metabolic checkpoint. However, the exact downstream contributors are not completely identified. BAG3 is a cochaperone with multiple cellular functions and is implicated in metabolic reprogramming of pancreatic cancer cells. The current study demonstrated that glucose limitation transcriptionally suppressed BAG3 expression in a p53‐dependent manner. Importantly, hinderance of its down‐regulation compromised cellular adaptation to metabolic stress triggered by glucose insufficiency, supporting that BAG3 might be one of p53 downstream contributors for cellular adaptation to metabolic stress. Our data showed that ectopic BAG3 expression suppressed p53 accumulation via direct interaction under metabolic stress. Thereby, the current study highlights the significance of p53‐mediated BAG3 suppression in cellular adaptation to metabolic stress via facilitating p53 accumulation.

Abstract
The traditional sulfur fumigation processing method has been widely used in the initial processing and storage of traditional Chinese medicinal materials due to its economy, efficiency, convenience, high operability and effect on mold and insect prevention. However, excessive sulfur fumigation of traditional Chinese medicinal materials would lead to the changes in chemical compositions, and even endanger human health. This study showed that traditional Chinese medicinal materials were sulfur fumigated directly after being harvested for quick drying, or fumigated after being weted in the storage process for preventing mold and insects. We found that the sulfur dioxide limits for traditional Chinese medicinal materials were stricter than those for foods. Based on the existing limit standards, we obtained the data of sulfur dioxide residues for 35 types of traditional Chinese medicinal materials in a total of 862 batches. According to the limit standard in the Chinese Pharmacopoeia (150, 400 mg·kg⁻¹), the average over-standard rate of sulfur dioxide was as high as 52.43%, but it was reduced to 29.47% if calculated based on the limit for vegetable additive standard (500 mg·kg⁻¹). Sulfur fumigation issue shall be considered correctly: sulfur dioxide is a type of low toxic substance and less dangerous than aflatoxin and other highly toxic substances, and a small amount of residue would not increase the toxicity of traditional Chinese medicinal materials. However, sulfur fumigation might change the content of chemical substances and affect the quality of traditional Chinese medicinal materials. Furthermore, the exposure hazards of toxic substances are comprehensively correlated with exposure cycle, exposure frequency, and application method. In conclusion, it is suggested to strengthen the studies on the limit standard of traditional Chinese medicinal materials, formulate practical and feasible limit standard for sulfur dioxide residues in traditional Chinese medicinal materials that are consistent with the medication characteristics of traditional Chinese medicinal materials and can guarantee people's demand for safe medication.

Abstract
Glucose limitation activates p53, which functions as an adaptive response to maintain cell survival. However, p53 is frequently deleted or mutated in a variety of tumors, while most cancer cells can acclimatize themselves to metabolically unfavorable surrounding, indicating that alternative mechanisms other than p53 transactivation underly adaptive response of cancer cells with p53 deletion or mutation to metabolically hostile environment. Sestrin 2 (SESN2) is a p53 downstream target, which plays a protective role against various stressful stimuli, such as genotoxic, energetic, and oxidative stress. In the current study, we demonstrated that SESN2 transcript was stabilized by glucose limitation at the posttranscriptional level irrespective of p53 status. Importantly, SESN2 also protected cells from metabolic stress triggered by glucose limitation in a p53-independent manner. Our data indicated that stabilization of SESN2 transcript might be an alternative adaptive response to metabolic stress other than p53 activation. Thereby, the current study highlights the significance of stabilization of SESN2 transcript in adaptation of cells with p53 deletion or mutation to metabolic stress.

Abstract
BAG3 is constitutively expressed in multiple types of cancer cells and its high expression is associated with tumour progression and poor prognosis of PDAC. However, little is known about the role of BAG3 in the regulation of stromal microenvironment of PDAC. The current study demonstrated that beside PDAC tumour cells, BAG3 was also expressed in some activated stroma cells in PDAC tissue, as well as in activated PSCs. In addition, the current study demonstrated that BAG3 expression in PSCs was involved in maintenance of PSCs activation and promotion of PDACs invasion via releasing multiple cytokines. The current study demonstrated that BAG3‐positive PSCs promoted invasion of PDACs via IL‐8, MCP1, TGF‐β2 and IGFBP2 in a paracrine manner. Furthermore, BAG3 sustained PSCs activation through IL‐6, TGF‐β2 and IGFBP2 in an autocrine manner. Thereby, the current study provides a new insight into the involvement of BAG3 in remodelling of stromal microenvironment favourable for malignant progression of PDAC, indicating that BAG3 might serve as a potential target for anti‐fibrosis of PDAC.

Abstract
Rhizosphere bacteria play a vital role in plant nutrition absorption,growth and disease resistance. In this study,high-throughput sequencing technology was used to analyze the rhizosphere bacterial communities of Salvia miltiorrhiza and S. miltiorrhiza f. alba. Moreover,the function of dominant rhizosphere bacterial communities was analyzed. We found that Sphingobacteriales,Sphingomonadales and Nitrosomonadaceae were both dominant and specific bacteria in the rhizosphere of S. miltiorrhiza. The main functions of dominant rhizosphere bacteria communities in both species include promoting transformation of soil nutrients,improving plant immunity and ability of stress tolerance. This study was the first to compare rhizobacterial communities structure and function of S. miltiorrhiza and S. miltiorrhiza f. alba,which provided a new theoretical reference for studing the rhizosphere mechanism of healthy S. miltiorrhiza planting in the future.

Abstract
Pancreatic stellate cells (PSCs) are a subset of pancreatic cancer-associated fibroblasts, which play a critical role in pancreatic fibrosis, a characteristic feature of pancreatic cancer. The interplay between PSCs and pancreatic cancer cells is vital for promotion of tumor progression and metastasis. BAG3 is correlated with poor prognostics in patients with pancreatic ductal adenocarcinoma (PDAC), however, the exact mechanisms remain largely unknown. In this study, we demonstrated that BAG3 downregulation decreased IL6 release by PDACs, and IL6 reduction was, at least partially, responsible for suppression of PSCs activation by PDACs with BAG3 downmodulation. Importantly, BAG3 expression positively correlated with fibrosis in pancreatic cancer tissue. With regard to the underlying mechanism, we demonstrated that BAG3 knockdown facilitated recruitment of Agonaute 2 (Ago2) to IL6 mRNA, resulting in destabilization of IL6 mRNA. In addition, the current study demonstrated that phosphorylation at Serine (Ser) 387 site was required for recruitment of Ago2-containing miRISC to IL6 mRNA and BAG3 knockdown facilitated Ago2 loading to IL6 mRNA via increasing its phosphorylation at Ser 387. This study shed new light on the tumor-promoting role of BAG3 in PDAC tumors, suggesting BAG3 might represent an interesting therapeutic opportunity to PDAC patients.

Abstract
Bcl-2 associated athanogene 3 (BAG3) is an important molecule that maintains oncogenic features of cancer cells via diverse mechanisms. One of the important functions assigned to BAG3 is implicated in selective macroautophagy/autophagy, which attracts much attention recently. However, the mechanism underlying regulation of autophagy by BAG3 has not been well defined. Here, we describe that BAG3 enhances autophagy via promotion of glutamine consumption and glutaminolysis. Glutaminolysis initiates with deamination of glutamine by glutaminase (GLS), by which yields glutamate and ammonia in mitochondria. The current study demonstrates that BAG3 stabilizes GLS via prohibition its interaction with SIRT5, thereby hindering its desuccinylation at Lys158 and Lys164 sites. As an underlying molecular mechanism, we demonstrate that BAG3 interacts with GLS and decreases SIRT5 expression. The current study also demonstrates that occupation by succinyl at Lys158 and Lys164 sites prohibits its Lys48-linked ubiquitination, thereby preventing its subsequent proteasomal degradation. Collectively, the current study demonstrates that BAG3 enhances autophagy via stabilizing GLS and promoting glutaminolysis. For the first time, this study reports that succinylation competes with ubiquitination to regulate proteasomal GLS degradation.

Abstract
Nowadays, the cultivation of traditional Chinese medicinal materials is faced with the problems of pesticides illegal uses and pesticides residues. In the early period of eco-agriculture of Chinese materia medica, the uses of pesticides in special time is still inevitable. However, the registration of pesticides for Chinese medicinal materials now is far from enough to meet demand. So it is necessary to publish policies to expand the pesticides registration for Chinese medicinal materials. We collected and analyzed the data of pesticide registration for Chinese medicinal materials, the results showed that till March 2018, there were 10 kinds of Chinese medicinal materials, 91 pesticide products and 46 kinds of pesticide ingredients registered. Based on the current status of the pesticide management in China and the experience of the registration pesticide for minor crops in countries around the world, we point out that the pesticide registration for Chinese medicinal materials should be carried out in the form of minor crops and some specific methods are also provided in this paper.

Abstract
The soil fertility has great impacts on the yielding of Chinese medicinal materials, as well as the generation of major components. The practices showed that soil fertility has been decayed with the growth of cultivation years,which is leading to adverse effect on quality and quantity of Chinese medicinal materials. However, there was a lack of domestic unified standard for assessment of soil fertility of Chinese medicinal material cultivation, which has seriously limited the soil management and quality control. In this text, we reviewed the progress on research of soil fertility evaluation, built the soil fertility evaluation index including soil texture,soil bulk density,soil organic matter,soil acidity and alkalinity,soil available nitrogen,soil available phosphorus, soil available potassium,soil animals and soil microorganisms. It would provide the direction and thought for standard-settin on soil fertility evaluation of Chinese medicinal material cultivation.

Abstract
As Gastrodiae Rhizoma (GR) is one of the herbs more seriously affected by sulfur fumigation, so its quality has been always of a great concern. In this paper, GR samples collected from eight main producing areas and in three forms were fumigated with sulfur and quantitatively and qualitatively analyzed based on UPLC-Q-TOF-MS/MS. The results showed that the contents of gastrodin, parishin, parishin B and parishin C were decreased, while the content of parishin E was increased after sulfur fumigation treatment. Besides, a new sulfur marker named p-hydroxybenzyl hydrogen sulfite was produced in sulfur-fumigated GR samples. As compared with producing origins, forms had a greater impact on the quality of GR, especially in Hongtianma and Wutianma. Besides, the contents of gastrodins and parishins in Hongtianma from Jilin were lowest as compared with those in other producing areas. This might be correlated with planting patterns and environmental factors. In conclusion, sulfur fumigation has a more obvious impact on the quality of GR than origins and forms, which is attributed to the generation of new sulfur fumigated markers.

Abstract
Studies on the characteristic chemical markers of sulfur fumigation have become an effective auxiliary way for quality control of traditional Chinese medicine. This study established a quantitative analysis method for the determination of p-hydroxybenzyl hydrogen sulfite (p-HS) in Gastrodiae Rhizoma (GR) based on UPLC-MS/MS. Then, 37 batches of GR were screened, and the results showed that 27 batches of them were sulfur-fumigated. Especially, the GR samples in Yunnan producing areas were sulfur-fumigated more seriously. Based on the stability of p-HS after different storage time and heat treatment methods, it was found that the content of p-HS was stable and reliable in the storage period of 8 months and under normal heat treatment (50, 60, 70, 80 °C) conditions. In conclusion, this study shows a high sensitivity, good selectivity and good stability of p-HS, which can provide reference for the quality control and sulfur fumigation screening of GR.

Abstract
Achyranthes bidentata Blume (AB) is a health food and a sulfur-free herbal medicine that is one of the most heavily sulfur-fumigated herbs in the marketplace. In this work, a comprehensive approach using ultra-performance liquid chromatography coupled with quadrupole time-of-flight-MS (UPLC-Q-TOF-MS) and multivariate statistical analysis was developed to identify characteristic sulfur-fumigation markers, elucidate chemical transformation mechanisms and characterize the degree of sulfur-fumigation of AB. Non-fumigated and sulfur-fumigated AB samples were compared by UPLC-Q-TOF-MS/MS analysis. Three triterpene saponins (Betavulgarosides II-IV) and two amides (Feruloyl-4-O-methyldopamine and Moupinamide) were identified as characteristic markers, which were positively correlated with two active AB components, namely oleanic acid and ferulic acid, respectively. Moreover, the extent of the sulfur-fumigation under different weight ratios of sulfur to herbal materials (1:20, 1:40, and 1:80) was analyzed based on chemical transformations and sulfur dioxide residues. Further verification showed that the ratio of 1:40 within 1 h was reasonable and efficient for herb quality preservation and assurance. This study provides a reliable sulfur-fumigation protocol for the quality control of AB and other herbs.

Abstract
To study the effect of different storage time on the chemical compositions and sulfur dioxide residues of sulfur-fumigated Gastrodiae Rhizoma (GR), and provide scientific basis for solving the quality and safety issues of sulfur-fumigated traditional Chinese medicinal materials. GR, sulfur-fumigated GR and its medicinal slices were stored under the same conditions, and then 8 active ingredients and sulfur dioxide residues were measured respectively. The results showed that the content of gastrodins in sulfur-fumigated GR and its medicinal slices was significantly lower than that in the non-fumigated GR. Moreover, the content of sulfur dioxide residue in sulfur-fumigated GR was significantly higher than that in its medicinal slices. That is to say, sulfur fumigation degree had significantly higher effect on GR quality as compared with its medicinal slices. During the whole storage time (8 months), the content of the eight chemical components in GR was not changed greatly in general. However, after the storage for 4 months, the content of 8 components and sulfur dioxide residues in all of GR samples were significantly changed. In particular, the content of sulfur dioxide residue in GR medicinal materials decreased up to 50% or more.

Abstract
Posttranscriptional regulation process plays important roles in renal disease pathogenesis. AU-rich element RNA-binding protein (AUF1) interacts with and destabilizes mRNAs containing AU-rich elements (AREs) in their 3'UTR. The current study demonstrated that AUF1 was increased in unilateral ureteral obstruction (UUO) animal models. While proliferation and migration of HK2 cells was unaltered by AUF1 downregulation under normal condition, proliferative inhibition and migratory promotion mediated by TGF-β was significantly compromised. Mechanically, AUF1 downregulation decreased phosphorylated Smad2/3 via increasing their E3 ligase Nedd4L at the posttranscriptional level. In addition, the current study identified Nedd4L as a previously unreported target of AUF1. AUF1 regulates Nedd4L expression at the posttranscriptional level by interaction with AREs in the 3'UTR of the Nedd4L mRNA. Collectively, the current study indicates that AUF1 might be a potential player in renal tubulointerstitial fibrosis through modulation of TGF-β signal transduction via posttranscriptional regulation of Nedd4L.

Abstract
Bcl-2 associated athanogene 3 (BAG3) contains a modular structure, through which BAG3 interacts with a wide range of proteins, thereby affording its capacity to regulate multifaceted biological processes. BAG3 is often highly expressed and functions as a pro-survival factor in many cancers. However, the oncogenic potential of BAG3 remains not fully understood. The cell cycle regulator, S-phase kinase associated protein 2 (Skp2) is increased in various cancers and plays an important role in tumorigenesis. The current study demonstrated that BAG3 promoted proliferation of ovarian cancer cells via upregulation of Skp2. BAG3 stabilized Skp2 mRNA via its 3'-untranslated region (UTR). The current study demonstrated that BAG3 interacted with Skp2 mRNA. In addition, miR-21-5p suppressed Skp2 expression, which was compromised by forced BAG3 expression. These results indicated that at least some oncogenic functions of BAG3 were mediated through posttranscriptional regulation of Skp2 via antagonizing suppressive action of miR-21-5p in ovarian cancer cells.

Abstract
The occurrence and progression of hepatocellular carcinoma (HCC) are affected by complicated signal transduction factors. Our previous study identified Ikaros as a novel reactivated therapeutic target that acts as a transcriptional repressor and reactivates anticancer mechanisms in HCC therapy. Annexin A4 (ANXA4) is a member of the Annexin family that plays an essential role in several cancers, but it has not been investigated in HCC proliferation. Using cDNA microarrays, ANXA4 was shown to be associated with Ikaros in Ikaros-overexpressing cells. The aim of this work was to characterize the relationship between Ikaros and ANXA4 and the role of ANXA4 in HCC. The effect of Ikaros on ANXA4 was analyzed in HCC cell lines and HCC patient samples, and functional recovery experiments were performed between Ikaros and ANXA4. Furthermore, the effect of ANXA4 on cell proliferation in vitro was analyzed by MTT and colony formation assays in HCC cells. We used a subcutaneous xenograft model to elucidate the role of ANXA4 in vivo. We found that ANXA4 overexpression promotes HCC cell proliferation, but Ikaros can inhibit ANXA4 expression by repressing its promoter activity. Moreover, we demonstrated that downregulated expression of ANXA4 inhibited HCC cell proliferation and tumorigenesis in vitro and in vivo. Our findings indicate that ANXA4 may be a critical factor in HCC tumorigenesis. Ikaros is an attractive inhibitor of ANXA4 and may function as an anticancer agent in HCC.

Abstract
Objectives: To study the relationship between the anatomical parameters of transverse foramen and intervertebral discs in the cross-section of the cervical spine in healthy adults, and to evaluate the risk of vertebral artery injury in the anterior cervical spine surgery. Methods: There were 24 healthy adults(12 male, 12 female) underwent neck CT angiography with clear vertebral artery and the adjacent structure imaging from June to December 2014 in Huashan Hospital, Fudan University. The anatomical parameters of vertebral artery V2 segment with lower cervical vertebrae and intervertebral discs were measured by cross-sectional images of C(3-6). The corresponding parameters of different sex and both sides of the same segment were analyzed by independent samples t-test and paired t test, respectively. The least significant difference(LSD) t test was used to compare the corresponding data between different segments. Results: The vertebral artery was not walking in the middle of the transverse foramen in healthy individual, but partial medial, partial front walking. Transverse diameter of transverse foramen in male and female were 6.62-6.89 mm and 6.21-6.45 mm, and sagittal diameter was 5.41-6.48 mm and 5.40-6.10 mm, respectively.The transverse foramen were slightly oval. The distance between vertebral artery and midline in male and female were 14.23-16.12 mm and 13.60-15.04 mm, respectively, which was much larger than the width of cervical vertebral corpectomy. Compared with C(3-4), intervertebral disc, the transverse distance between the vertebral artery and the uncovertebral joint of C(4-5), C(5-6) was smaller, and the distance from the vertebral artery to the posterior margin of the uncovertebral joint was relatively small, the difference was statistically significant (t=2.449, P=0.022). The distance from vertebral artery to the posterior margin of uncinate process was 1/5-2/5 of the distance between the anterior and posterior edge of the corresponding segmental vertebra. Conclusion: Based on this anatomical study, the risk of vertebral artery injury in conventional anterior cervical decompression is small, and the risk of vertebral artery injury in different segments is slightly different.

Abstract
INTRODUCTION Lipopolysaccharide-binding protein (LBP) is widely reported as a biomarker to differentiate infected from non-infected patients. The diagnostic use of LBP for sepsis remains a matter of debate. We aimed to perform a systematic review and meta-analysis to assess the diagnostic accuracy of serum LBP for sepsis in adult patients. METHODS We performed a systematic review and meta-analysis to assess the accuracy of LBP for sepsis diagnosis. A systematic search in PubMed and EMBASE for studies that evaluated the diagnostic role of LBP for sepsis through December 2015 was conducted. We searched these databases for original, English language, research articles that studied the diagnostic accuracy between septic and non-septic adult patients. Sensitivity, specificity, and other measures of accuracy, such as diagnostic odds ratio (DOR) and area under the receiver operating characteristic curve (AUC) of LBP were pooled using the Hierarchical Summary Receiver Operating Characteristic (HSROC) method. RESULTS Our search returned 53 reports, of which 8 fulfilled the inclusion criteria, accounting for 1684 patients. The pooled sensitivity and specificity of LBP for diagnosis of sepsis by the HSROC method were 0.64 (95% CI: 0.56-0.72) and 0.63 (95% CI: 0.53-0.73), respectively. The value of the DOR was 3.0 (95% CI: 2.0-4.0) and the AUC was 0.68 (95% CI: 0.64-0.72). Meta-regression analysis revealed that cut-off values accounted for the heterogeneity of sensitivity and sample size (> = 150) accounted for the heterogeneity of specificity. CONCLUSIONS Based on the results of our meta-analysis, LBP had weak sensitivity and specificity in the detection of sepsis. LBP may not be practically recommended for clinical utilization as a single biomarker.

Abstract
We performed annealing control primer (ACP)-based differential-display reverse transcription-polymerase chain reaction (DDRT-PCR) to isolate differentially expressed genes (DEGs) from the stage IV ovary and ovotestis of the rice field eel, Monopterus albus. Using 20
arbitrary ACP primers, 14 DEG expressed-sequence tags were identified and sequenced. The transcriptional expression of one DEG, G2, was significantly greater in the ovotestis than the stage IV ovary. To understand the role of G2 in sex inversion, G2 cDNA was cloned and semi-RT-PCR, real time PCR were performed during gonad development. The full-length G2 cDNA was 650 base pairs (bp) and it comprised a 5′-untranslated region (UTR) of 82 bp, a 3′-UTR of 121 bp and an open reading frame of 444 bp that encoded a 148-amino acid protein. The expression of G2 was weak during early ovarian development
until the stage IV ovary, but expression increased significantly with gonad development. We speculate that G2 may play an important function during sex inversion and testis development in the rice field eel, but the full details of the function of this gene requires further research.

Abstract
We report a design of low-loss THz Bragg fibers with a core size on the order of wavelength that operates near the cutoff frequency of its TE01 mode. We also propose a broadband Y-type mode converter based on branched rectangular metallic waveguides to facilitate coupling between the TE01 mode of the Bragg fiber and the TEM mode in free space with 60% efficiency. Our fiber holds strong promise to facilitate beam-wave interaction in gyrotron for high-efficiency THz generation.

Abstract
Programmed necrosis or necroptosis is an alternative form of cell death that is
executed through a caspase-independent pathway. Necroptosis has been implicated in
many pathological conditions. Genetic or pharmacological inhibition of necroptotic
signaling has been shown to confer neuroprotection after traumatic and ischemic brain
injury. Therefore, the necroptotic pathway represents a potential target for
neurological diseases that are managed by neurosurgeons. In this review, we summarize
recent advances in the understanding of necroptotic signaling pathways and explore
the role of necroptotic cell death in craniocerebral trauma, brain tumors, and
cerebrovascular diseases.

Abstract
BACKGROUND Although Saccular intracranial aneurysm (sIA) is the most common type abnormality of all intracranial aneurysms, the biological mechanisms of sIA are not fully understood. METHODS We downloaded microarray datasets from Gene Expression Omnibus (GEO) database which includes 11 ruptured intracranial aneurysm samples and 8 unruptured intracranial aneurysm samples. Significant Analysis of Microarray (SAM) was employed to identify the differentially expressed genes (DEGs) between ruptured and unruptured intracranial aneurysms. RESULTS We found 2129 genes differentially expressed in rupture sIA, of which 1062 genes up-regulated and 1057 genes down-regulated. Functional analysis demonstrated these genes were significantly associated with inflammatory response, wounding response and defense response. Protein-protein interaction (PPI) analysis revealed that these genes may play important roles in the pathogenesis of sIAs. Results suggested that four transcription factors (TFs) could cooperated with each other, together with several microRNAs play roles in the pathonegensis of ruptured sIAs. CONCLUSIONS All of above results indicate the existence of DEGs between ruptured and unruptured sIAs, which regulating the pathogenesis of ruptured sIAs. TFs and microRNAs may also play key roles in ruptured sIAs. This research hints a new thought to the therapy of ruptured sIAs.

Abstract
Background In 2003, Plasmodium vivax malaria has re-emerged in central eastern China including Yongcheng prefecture, Henan Province, where no case has been reported for eleven years. Our goals were to detect the space-time distribution pattern of malaria and to determine significant environmental variables contributing to malaria incidence in Yongcheng from 2006 to 2010, thus providing scientific basis for further optimizing current malaria surveillance and control programs. Methods This study examined the spatial and temporal heterogeneities in the risk of malaria and the influencing factors on malaria incidence using geographical information system (GIS) and time series analysis. Univariate analysis was conducted to estimate the crude correlations between malaria incidence and environmental variables, such as mosquito abundance and climatic factors. Multivariate analysis was implemented to construct predictive models to explore the principal environmental determinants on malaria epidemic using a Generalized Estimating Equation (GEE) approach. Results Annual malaria incidence at town-level decreased from the north to south, and monthly incidence at prefecture-level demonstrated a strong seasonal pattern with a peak from July to November. Yearly malaria incidence had a visual spatial association with yearly average temperature. Moreover, the best-fit temporal model (model 2) (QIC = 16.934, P<0.001, R2 = 0.818) indicated that significant factors contributing to malaria incidence were maximum temperature at one month lag, average humidity at one month lag, and malaria incidence of the previous month. Conclusions Findings supported the effects of environment factors on malaria incidence and indicated that malaria control targets should vary with intensity of malaria incidence, with more public resource allocated to control the source of infections instead of large scale An. sinensis control when malaria incidence was at a low level, which would benefit for optimizing the malaria surveillance project in China and some other countries with unstable or low malaria transmission.

Random repeated cross sectional study on breeding site characterization of Anopheles sinensis larvae in distinct villages of Yongcheng City, People's Republic of China. Parasit Vectors 2012; 5:58.

Abstract
BACKGROUND Characterizing the breeding site of Anopheles sinensis is of major importance for the transition from malaria control to elimination in China. However, little information is available especially regarding the characteristics and influencing factors of breeding sites of An. sinensis in Yongcheng City, a representative region of unstable malaria transmission in the Huang-Huai River region of central China. The aims of this study were to determine the breeding site characteristics of An. sinensis and related environmental and physicochemical parameters, to find out which breeding site characteristics could best explain the presence of An. sinensis larvae, and to determine whether the breeding habit of An. sinensis has changed or not. METHODS Random repeated cross sectional study was undertaken in six villages of the Yongcheng city characterized by different levels of the historical incidence of P. vivax malaria. The potential breeding sites of An. sinensis larvae in each village were examined twice per month both in the household courtyards and the village surroundings. The larval sampling was done by the standard dipping method. Some important breeding site characterizations were recorded and characterized. The anopheline mosquito larvae and emerged adults were identified to the species level morphologically and to sub-species by the ribosomal DNA PCR technique. Chi-square analysis and logistic regression analysis were applied to determine the importance of factors for explaining the presence or absence of An. sinensis larvae. RESULTS According to the ribosomal DNA PCR assay, all sampled anopheline mosquito larvae and emerged adults belonged to An. sinensis. Only 3 containers that were sampled from the household courtyards were found to contain An. sinensis larvae. There were no differences in the species composition of mosquito larvae among containers that contained water in the household courtyards (P > 0.05). An. sinensis larvae were shown to be present in a total of 60 breeding sites in the village surroundings, this included 8 (13.3%) river fringes, 26 (43.3%) ponds, 23 (38.3%) puddles, and 3 (5.0%) irrigation/drainage ditches. Logistic regression analysis revealed that the breeding site type, water depth, chemical oxygen demand (COD), ammonia nitrogen, and sulphate were found to be the key factors determining the presence of An. sinensis larvae. Approximately 94.9% of An. sinensis larvae inhabited relatively large and medium-sized water bodies, with depths between 0.5 m and 1.0 m (73.3%), COD lower than 2 mg/L (75%), ammonia nitrogen lower than 0.4 mg/L (86.7%), and sulphate lower than 150 mg/L (58.3%), respectively. CONCLUSION These results indicate that the majority of An. sinensis larval breeding sites were relatively large and medium-sized water bodies with depths between 0.5 m and 1.0 m, and containing low levels of COD, ammonia nitrogen, and sulphate, respectively. For effective An. sinensis larval control, the type of breeding site, water depth, COD, ammonia nitrogen, and sulphate should be given higher priority over other factors in areas where it is the primary vector.
