Abstract
A novel acidic glucuronogalactomannan (STHP-5) was isolated from the aboveground part of Tetrastigma hemsleyanum Diels et Gilg with a molecular weight of 3.225 × 105 kDa. Analysis of chain conformation showed STHP-5 was approximately a random coil chain. STHP-5 was composed mainly of galactose, mannose, and glucuronic acid. Linkages of glycosides were measured via methylation analysis and verified by NMR. In vitro, STHP-5 induced the production of nitric oxide (NO) and secretion of IL-6, MCP-1, and TNF-α in RAW264.7 cells, indicating STHP-5 had stimulatory activity on macrophages. STHP-5 was proven to function as a TLR4 agonist by inducing the secretion of secreted embryonic alkaline phosphatase (SEAP) in HEK-Blue™-hTLR4 cells. The TLR4 activation capacity was quantitatively measured via EC50, and it showed purified polysaccharides had stronger effects (lower EC50) on activating TLR4 compared with crude polysaccharides. In conclusion, our findings suggest STHP-5 may be a novel immunomodulator.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tetrastigma hemsleyanum Diels et Gilg, is one of the perennial evergreen plants with grass vine, which has obvious curative effect on severe infectious diseases. Although Tetrastigma hemleyanum has long been recognized for its capacity of antipyretic and antitoxic, its specific mechanism is unknown. AIM OF THE STUDY To evaluate the antipyretic effect of Tetrastigma hemleyanum polysaccharide (THP) on mice with dry yeast-induced fever, and to explore its specific antipyretic mechanism. METHODS In this study, THP was administered by aerosol in febrile mice. The rectal temperatures of treated animals were monitored at different time points. Histopathological evaluation and various inflammatory indexes were used to assess inflammatory damage. The concentration variations of the central neurotransmitter, endocrine system, substance and energy metabolism indicators were measured to explore the physiological mechanism. Quantitative real-time PCR, Western bolt and Immunohistochemistry were performed to identify the correlation between antipyretic and TLR4/NF-κB signaling pathway. RESULTS THP reduced the body temperature of febrile mice induced by dry yeast, as well as the levels of thermogenic cytokines and downregulated the contents of thermoregulatory mediators. THP alleviated the pathological damage of liver and hypothalamus caused by fever. In addition, THP decreased the secretion of thyroid hormone, substance and energy metabolism related indicators. Furthermore, THP significantly suppressed TLR4/NF-κB signaling pathway-related indicators. CONCLUSIONS In conclusion, our results suggest that inhaled THP exerts antipyretic effect by mediating the thermoregulatory mediator, decreasing the content of pyrogenic factors to lower the body temperature, and eventually restoring the high metabolic level in the body to normal via inhibiting TLR4/NF-κB signaling pathway. The study provides a reasonable pharmacodynamic basis for the treatment of polysaccharide in febrile-related diseases.

Abstract
The anti-inflammatory activity of polysaccharides derived from Melastoma dodecandrum Lour. was evaluated in pyretic mice and HEK-Blue™ hTLR4 cells. The testing led to the identification of MDP2-1, which was then investigated for its structural characteristics and anti-inflammatory effects. Results showed that MDP2-1 had a molecular weight of 29.234 kDa and primarily consisted of galactose, arabinose, rhamnose, glucose, glucuronic acid, and galacturonic acid. Its main backbone was composed of →4)-α-D-GalpA-(1→, →2)-α-L-Rhap-(1→, →3,4)-α-D-GalpA-(1→, →2,4)-α-D-GlcpA-(1→, and its side chains were connected by →4)-α-D-Galp-(1→, α-D-Galp-(1→, →4)-β-D-Glcp-(1→, and α-L-Araf-(1→. In vivo experiments on mice demonstrated that MDP2-1 attenuated LPS-induced acute lung injury, and in vitro experiments on RAW264.7 cells showed that MDP2-1 reduced the levels of inflammatory mediators and mitigated LPS-induced inflammatory damage by inhibiting the activation of the TLR4 downstream NF-κB/MAPK pathway. These findings suggest that MDP2-1 is a novel anti-inflammatory agent for therapeutic interventions.

Abstract
The control of flowering time in maize is crucial for reproductive success and yield, and it can be influenced by environmental stresses. Using the approaches of Ac/Ds transposon and transposable element amplicon sequencing techniques, we identified a Ds insertion mutant in the ZmPRR37 gene. The Ds insertion showed a significant correlation with days to anthesis. Further research indicated that ZmPRR37-CR knockout mutants exhibited early flowering, whereas ZmPRR37-overexpression lines displayed delayed flowering compared to WT under long-day (LD) conditions. We demonstrated that ZmPRR37 repressed the expression of ZmNF-YC2 and ZmNF-YA3 to delay flowering. Association analysis revealed a significant correlation between flowering time and a SNP2071-C/T located upstream of ZmPRR37. The SNP2071-C/T impacted the binding capacity of ZmELF6 to the promoter of ZmPRR37. ZmELF6 also acted as a flowering suppressor in maize under LD conditions. Notably, our study unveiled that ZmPRR37 can enhance salt stress tolerance in maize by directly regulating the expression of ABA-responsive gene ZmDhn1. ZmDhn1 negatively regulated maize salt stress resistance. In summary, our findings proposed a novel pathway for regulating photoperiodic flowering and responding to salt stress based on ZmPRR37 in maize, providing novel insights into the integration of abiotic stress signals into floral pathways.

Abstract
Objective: To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023. Methods: The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed. Results: A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M (Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant (P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age (P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion: Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bletilla striata polysaccharides (BSP) extracted from the B. striata tuber, have been demonstrated to possess anti-inflammatory properties. However, their potential protective effect against ARDS and their role in regulating cell pyroptosis remained unexplored. AIM OF THE STUDY The aim of this study was to investigate the therapeutic effect of BSP in the alleviation of lipopolysaccharide (LPS)-induced ARDS, and to explore its mechanism of action. METHODS The effect of BSP was assessed by LPS injection into the intraperitoneal cavity in vivo; pathological changes of ARDS mice were gauged by immunohistochemical, hematoxylin and eosin staining, and immunofluorescence assays. MH-S cells were used to model the pyroptosis in vitro. Finally, the pyroptosis of alveolar macrophage was detected by western blots, qPCR, and flow cytometry for NLRP3/caspase1/GSDMD and HMGB1/TLR4 pathway-associated proteins and mRNA. RESULTS BSP could significantly increase the weight and survival rate of mice with ARDS, alleviate the cytokine storm in the lungs, and reduce lung damage in vivo. BSP inhibited the inflammation caused by LPS/Nigericin significantly in vitro. Compared with the control group, there was a remarkable surge in the incidence of pyroptosis observed in ARDS lung tissue and alveolar macrophages, whereas BSP significantly diminished the pyroptosis ratio. Besides, BSP reduced NLRP3/caspase1/GSDMD and HMGB1/TLR4 levels in ARDS lung tissue and MH-S cells. CONCLUSIONS These findings proved that BSP could improve LPS-induced ARDS via inhibiting pyroptosis, and this effect was mediated by NLRP3/caspase1/GSDMD and HMGB1/TLR4, suggesting a therapeutic potential of BSP as an anti-inflammatory agent for ARDS treatment.

Abstract
Triclosan (TCS) is a broad-spectrum antibacterial chemical widely presents in people's daily lives. Epidemiological studies have revealed that TCS exposure may affect female puberty development. However, the developmental toxicity after low-dose TCS continuous exposure remains to be confirmed. In our study, 8-week-old ICR female mice were continuously exposed to TCS (30, 300, 3000 μg/kg/day) or vehicle (corn oil) from 2 weeks before mating to postnatal day 21 (PND 21) of F1 female mice, while F1 female mice were treated with TCS intragastric administration from PND 22 until PND 56. Vaginal opening (VO) observation, hypothalamic-pituitary-ovarian (HPO) axis related hormones and genes detection, and ovarian transcriptome analysis were carried out to investigate the effects of TCS exposure on puberty onset. Meanwhile, human granulosa-like tumor cell lines (KGN cells) were exposed to TCS to further explore the biological mechanism of the ovary in vitro. The results showed that long-term exposure to low-dose TCS led to approximately a 3-day earlier puberty onset in F1 female mice. Moreover, TCS up-regulated the secretion of estradiol (E2) and the expression of ovarian steroidogenesis genes. Notably, ovarian transcriptomes analysis as well as bidirectional validation in KGN cells suggested that L-type calcium channels and Pik3cd were involved in TCS-induced up-regulation of ovarian-related hormones and genes. In conclusion, our study demonstrated that TCS interfered with L-type calcium channels and activated Pik3cd to up-regulate the expression of ovarian steroidogenesis and related genes, thereby inducing the earlier puberty onset in F1 female mice.

Abstract
Although cisplatin is an effective chemotherapy drug for the treatment of various cancers, its clinical use is limited due to its side effects, especially nephrotoxicity. Unfortunately, acute kidney injury (AKI) caused by cisplatin remains one of the main challenges in effective cancer treatment. Evidence increasingly suggests that renal inflammation and pyroptotic inflammatory cell death of renal tubular epithelial cells (RTECs) mainly determine the progression and outcome of cisplatin-induced AKI. However, it is not clear how cisplatin regulates the pyroptosis of RTECs cells in AKI. The current study aimed to determine the regulation mechanism of AKI induced by cisplatin. We used cisplatin to induce AKI in vivo. We performed H&E staining of mouse kidney tissue sections and evaluated serological indicators of kidney injury (including blood urea nitrogen (BUN), serum creatinine, and tumor necrosis factor-alpha (TNF-alpha)). We used immunohistochemistry and western blot to detect the important substrate protein gasdermin D (GSDMD) and key target caspase-1 of pyroptosis, respectively. Cisplatin induced mouse AKI and RTECs pyroptosis. HK2 cell-derived exosomes treated with cisplatin influenced pyroptosis of the surrounding HK2 cells. Cisplatin-treated HK2 cells exosome-derived miR-122 regulated pyroptosis in the surrounding cells. Exosome-derived miR-122 affected cisplatin-induced AKI and HK2 cells pyroptosis by regulating the expression of embryonic lethal abnormal vision (ELAVL1). These results suggest that exosome miR-122 inhibited pyroptosis and AKI by targeting ELAVL1 under cisplatin treatment, and this offers a potential target for the treatment of AKI.

Abstract
The healing process of a diabetic wound (DW) is often impeded by a series of interrelated factors, including severe infection, persistent inflammation, and excessive oxidative stress. Therefore, it is particularly crucial to develop a medical dressing that can address these issues simultaneously. To this end, different ratios of Bletilla striata polysaccharide (BSP) and berberine (BER) were physically blended with Carbomer 940 (CBM940) to develop a composite hydrogel as a medical dressing. The BSP/BER hydrogel was characterized using SEM, FTIR, rheological testing and other techniques. The anti-inflammatory, antioxidant, and antibacterial properties of the hydrogel were evaluated using cell and bacterial models in vitro. A DW model of ICR mice was established to evaluate the effect of the hydrogel on DW healing in vivo. The hydrogel exhibited excellent biocompatibility and remarkable antibacterial, anti-inflammatory, and antioxidant properties. In addition, animal experiments showed that the BSP/BER hydrogel significantly accelerated wound healing in DW mice. Among the different formulations, the LBSP/BER hydrogel (2% BSP, mBER:mBSP = 1:40) demonstrated the most remarkable efficacy. In conclusion, the BSP/BER hydrogel developed exhibited immense properties and great potential as a medical dressing for the repair of DW, addressing a crucial need in clinical practice.

Abstract
HPLC method is the standard method for the separation and quantification of impurities from quinolone antibiotics. However, due to the large differences in the UV absorption of the impurities in quinolone antibiotics, quantitative analysis without the availability of corresponding reference substances currently poses a challenge. A sensitive and direct method using high performance liquid chromatography coupled with diode array detector and charged aerosol detector (HPLC-DAD-CAD) was developed for the analysis of impurities in quinolone antibiotics. The chromatographic conditions were optimized for good separation and output signal of CAD detector by response surface method (RSM). The systematic variation of CAD parameter settings, such as nebulization temperature, filter constant and power function value (PFV), were used to study the effect of on the detector response of signal-to-noise ratios (S/N) and linearity for ofloxacin, ciprofloxacin and their impurities. In the method validation, good linearity of each component was obtained with coefficient of determination (r) greater than 0.999 in the range of 0.5-300 μg mL-1. The average recoveries of each component were 99.02-102.39 % by DAD, were 98.22-101.91 % by CAD, RSDs were less than 2.5 % for intra-day and inter-day precision by DAD-CAD, with good precision and accuracy. The correction factor experimental results showed that the developed method provided a uniform response to the impurities with differences chromophores and could unbiasedly and directly detect the impurities in quinolone antibiotics. The method is first reported application of HPLC-DAD-CAD method for the analysis of impurities in quinolone antibiotics and it can be used for quality control of quinolone antibiotics.

Abstract
In this study, the therapeutic effects of Tetrastigma hemsleyanum polysaccharide (THP) on inflammatory bowel disease (IBD) and its possible mechanisms were investigated based on the IBD mouse model induced by dextran sodium sulfate (DSS) and the lipopolysaccharide (LPS)-stimulated Caco-2 cell model. THP significantly alleviated the signs and symptoms of DSS-induced IBD mice, including the reduced weight, shortened colonic length, and increased colitis disease activity index. In vivo, THP significantly reduced inflammatory cell infiltration and oxidative damage, promoted intestinal mucus secretion, and restored the integrity of the intestinal epithelial barrier and mucus barrier. Furthermore, THP reversed the changes in the intestinal flora of colonized mice and restored the levels of short-chain fatty acids (SCFAs) by increasing the abundance of potentially beneficial bacteria and increasing the abundance of butyrate-producing bacteria. In addition, THP upregulated the expression of G-protein-coupled receptors (GPR41 and GPR43) both in vivo and in vitro. In summary, the current investigation showed that THP effectively protected against intestinal inflammation and impairment in the intestinal barrier in the setting of DSS-induced IBD, possibly by regulating gut microbiota structure and corresponding SCFA metabolites, and the pathway of SCFAs action may be related to SCFA-GPR41/43 signaling pathway.

Abstract
Diabetic wounds impose enormous distress and financial burden on patients, and finding effective dressings to manage wounds is critical. As a Chinese herbal medicine with a long history of Clinical application, Bletilla striata has significant medicinal effects in the therapy of various wounds. In this study, PLA and the pharmacodynamic substances of Bletilla striata were prepared into fibrous scaffolds by emulsion electrospinning technology for the management of diabetic wounds in mice. The results of scanning electron microscopy showed that the core-shell structure fibre was successfully obtained by emulsion electrospinning. The fibre membrane exhibited excellent water absorption capability and water vapor transmission rate, could inhibit the growth of Staphylococcus aureus and Pseudomonas aeruginosa, had good compatibility, and achieved excellent healing effect on diabetic wounds. Especially in the in vivo wound healing experiment, the wound healing rate of composite fibre membrane treatment reached 98.587 ± 2.149% in 16 days. This work demonstrated the good therapeutic effect of the developed fibrous membrane to diabetic wound, and this membrane could be potentially applied to chronic wound healing.

Abstract
A new reduced phase derived from the excitonic insulator candidate Ta2NiSe5 has been synthesized via the intercalation of lithium. LiTa2NiSe5 crystallizes in the orthorhombic space group Pmnb (no. 62) with lattice parameters a = 3.50247(3) Å, b = 13.4053(4) Å, c = 15.7396(2) Å, and Z = 4, with an increase of the unit cell volume by 5.44(1)% compared with Ta2NiSe5. Significant rearrangement of the Ta-Ni-Se layers is observed, in particular a very significant relative displacement of the layers compared to the parent phase, similar to that which occurs under hydrostatic pressure. Neutron powder diffraction experiments and computational analysis confirm that Li occupies a distorted triangular prismatic site formed by Se atoms of adjacent Ta2NiSe5 layers with an average Li-Se bond length of 2.724(2) Å. Li-NMR experiments show a single Li environment at ambient temperature. Intercalation suppresses the distortion to monoclinic symmetry that occurs in Ta2NiSe5 at 328 K and that is believed to be driven by the formation of an excitonic insulating state. Magnetometry data show that the reduced phase has a smaller net diamagnetic susceptibility than Ta2NiSe5 due to the enhancement of the temperature-independent Pauli paramagnetism caused by the increased density of states at the Fermi level evident also from the calculations, consistent with the injection of electrons during intercalation and formation of a metallic phase.

Abstract
Traditional Chinese medicine (TCM) that is used worldwide possesses the satisfactory function of disease prevention, treatment and health care, and this natural medicine seems to be favored due to its low side effects. Endocrine disrupting chemicals (EDCs), which exist in all aspects of our lives, may interfere with the synthesis, action and metabolism of human sex steroid hormones, resulting in the development and fertility problems as well as obesity and the disturbance of energy homeostasis. From planting to processing, TCM may be polluted by various EDCs. Many studies pay attention to this problem, but there are still few reviews on the residues and toxicity risks of EDCs in TCM. In this paper, researches related to EDCs in TCM were screened. The possible contamination sources of TCM from planting to processing and its toxic effects were introduced. Moreover, the residues of metals, pesticides and other EDCs in TCM as well as the health risks of human exposure to EDCs through ingestion of TCM materials were reviewed.

Abstract
OBJECTIVE To explore the influential factors associated with functional status of those patients who undertook a full-endoscopic lumbar discectomy operation. METHODS A prospective study was conducted. A total of 96 patients who undertook a full-endoscopic lumbar discectomy operation and met inclusive criteria were enrolled in the study. The postoperative follow-up was held 1 month, 3 months and 6 months after operation. The self-developed record file was used to collect the patient's information and medical history. Visual analogue scale (VAS) score, Oswestry disability index (ODI) score, Gene-ralised anxiety disorder-7 (GAD-7) scale score and patient health questionnaire-9 (PHQ-9) scale score were applied to measure pain intensity, functional status, anxiety status and depression status. Repeated measurement analysis of variance was used to explore the ODI score 1 month, 3 months and 6 months after operation. Multiple linear regression was recruited to illuminate the influential factors associated with functional status after the operation. Logistic regression was employed to explore the independent risk factors related to return to work 6 months after operation. RESULTS The postoperative functional status of the patients improved gradually. The functional status of the patients 1 month, 3 months and 6 months after operation were highly positively correlated with the current average pain intensity. The factors influencing the postoperative functional status of the patients were different according to the recovery stage. One month and 3 months after operation, the factors influencing the postoperative functional status were the current average pain intensity; 6 months after operation, the factors influencing the postoperative functional status included the current average pain intensity, preoperative average pain intensity, gender and educational level. The risk factors influencing return to work 6 months after operation included women, young age, preoperative depression status and high average pain intensity 3 months after operation. CONCLUSION It is feasible to treat chronic low back pain with full-endoscopic lumbar discectomy operation. In the process of postoperative functional status recovery, medical staffs should not only take analgesic mea-sures to reduce the pain intensity experienced by the patients, but also pay attention to the impact of psychosocial factors on the recovery. Women, young age, preoperative depression status, and high average pain intensity 3 months after operation may delay return to work after the operation.

Abstract
Thermal processing is one of the important techniques for most of the plant-based food and herb medicines before consumption and application in order to meet the specific requirement. The plant and herbs are rich in amino acids and reducing sugars, and thermal processing may lead to Maillard reaction, resulting as a high risk of acrylamide pollution. Acrylamide, an organic pollutant that can be absorbed by the body through the respiratory tract, digestive tract, skin and mucous membranes, has potential carcinogenicity, neurological, genetic, reproductive and developmental toxicity. Therefore, it is significant to conduct pollution determination and risk assessment for quality assurance and security of medication. This review demonstrates state-of-the-art research of acrylamide focusing on the toxicity, formation, contamination, determination, and mitigation in taking food and herb medicine, to provide reference for scientific processing and ensure the security of consumers.

Abstract
Ofloxacin ear drops contain a large proportion of organic solvents, which have a great effect on the photodegradation of ofloxacin. The photodegradation impurities of ofloxacin in aqueous solution has been studied, however, the photodegradation of ofloxacin in non-aqueous solution with a high proportion of organic solvents has not been reported. In this article, the impurity profile in non-aqueous ofloxacin ear drops was studied for further improvement of official monograph in pharmacopoeia and quality control of drug. The liquid chromatography combined with ion trap/time-of-flight mass spectrometry was applied to separate and characterize the structures of the impurities in non-aqueous ofloxacin ear drops. Mass fragmentation pattern of ofloxacin and its impurities were studied. The structures of seventeen impurities in ofloxacin ear drops were elucidated based on the high-resolution MSn data in positive ion modes, and ten of them were unknown impurities. The results showed that the impurity profile of non-aqueous ofloxacin solution was significantly different from that of aqueous ofloxacin solution. The effects of packaging materials and excipients on the photodegradation of ofloxacin ear drops were also investigated. The results of correlation analysis showed that the packaging materials with low light transmittance could reduce the light degradation, and ethanol of excipients could significantly decrease the light stability of ofloxacin ear drops. This study revealed the impurity profile and key factors affecting the photodegradation of non-aqueous ofloxacin ear drops, and guided enterprises to improve drug prescription and packaging materials to ensure the safety of drug use by the public.

Abstract
Anaplastic lymphoma kinase (ALK) rearrangements occur in ∼3%-6% of patients with advanced non-small-cell lung cancer (NSCLC). Small molecular drugs that effectively inhibit ALK gene have revolutionized the therapeutic paradigm for patients with ALK rearrangements, resulting in significant improvements in objective response rate, progression-free survival, and overall survival compared with classical platinum-based chemotherapy. Several ALK tyrosine kinase inhibitors (ALK-TKIs), including crizotinib, alectinib, ceritinib, brigatinib, ensartinib, and lorlatinib, have been recommended as standard first-line treatment for advanced NSCLC patients with ALK rearrangements. Patients with ALK rearrangements typically exhibit long-term durable responses to ALK-TKIs; therefore, the management of adverse drug reactions (ADRs) with ALK-TKIs is crucial in clinical practice to maximize clinical benefits, prevent an adverse impact on quality of life, and improve patient compliance. In general, ALK-TKIs are well tolerated. There are, however, a number of serious toxicities that may necessitate dose modification or even discontinuation of treatment and the management of ADRs with ALK-TKIs has grown in importance. The therapeutic use of this class of medications still carries some risk because there are currently no pertinent guidelines or consensus recommendations for managing ADRs caused by ALK-TKIs in China. In order to improve the clinical management of ADRs with ALK-TKIs, the Chinese Society of Clinical Oncology (CSCO) Non-small Cell Lung Cancer Professional Committee led the discussion and summary of the incidence, diagnosis and grading standards, and prevention and treatment of ADRs caused by ALK-TKIs.

Abstract
OBJECTIVE To predict the targets and pathways in the therapeutic mechanism of Guizhi Gancao Decoction (GZGCD) against heart failure (HF) based on network pharmacology. METHODS The chemical components of GZGCD were analyzed using the databases including TCMSP, TCMID and TCM@Taiwan, and the potential targets of GZGCD were predicted using the SwissTargetPrediction database. The targets of HF were obtained using the databases including DisGeNET, Drugbank and TTD. The intersection targets of GZGCD and HF were identified using VENNY. Uniport database was used to convert the information, and the components-targets-disease network was constructed using Cytoscape software. The Bisogene plug-in, Merge plug-in, and CytoNCA plug-in in Cytoscape software were used for protein-protein interaction (PPI) analysis to acquire the core targets. Metascape database was used for GO and KEGG analysis. The results of network pharmacology analysis were verified with Western blot analysis. Three factors (PKCα, ERK1/2 and BCL2) were screened according to the degree value of network pharmacology results and the degree of correlation with heart failure process. The pentobarbtal sodium was dissolvein H9C2 cells treated with serum-free high glucose medium to simulate the ischemic anoxic environment of heart failure. The total proteins of myocardial cells were extracted. The protein contents of PKCα, ERK1/2 and BCL2 were determined. RESULTS We identified a total of 190 intersection targets between GZGCD and HF using Venny database, involving mainly the circulatory system process, cellular response to nitrogen compounds, cation homeostasis, and regulation of the MAPK cascade. These potential targets were also involved in 38 pathways, including the regulatory pathways in cancer, calcium signal pathway, cGMP-PKG signal pathway, and cAMP signal pathway. Western blot analysis showed that in an in vitro H9C2 cell model of HF, treatment with GZGCD downregulated PKCα and ERK1/2 expressions and upregulated BCL2 expression. CONCLUSION The therapeutic mechanism of GZGCD for HF involves multiple targets including PRKCA, PRKCB, MAPK1, MAPK3, and MAPK8 and multiple pathways including the regulatory pathway in cancer and the calcium signaling pathway.

Abstract
Objective: To investigate dose-response associations between fluid overload (FO) and hospital mortality in patients with sepsis. Methods: The current cohort study was prospective and multicenter. Data were derived from the China Critical Care Sepsis Trial, which was conducted from January 2013 to August 2014. Patients aged≥18 years who were admitted to intensive care units (ICUs) for at least 3 days were included. Fluid input/output, fluid balance, fluid overload (FO), and maximum FO (MFO) were calculated during the first 3 days of ICU admission. The patients were divided into three groups based on MFO values: MFO<5%L/kg, MFO 5%-10%L/kg, and MFO≥10% L/kg. Kaplan-Meier analysis was used to predict time to death in hospital in the three groups. Associations between MFO and in-hospital mortality were evaluated via multivariable Cox regression models with restricted cubic splines. Results: A total of 2 070 patients were included in the study, of which 1 339 were male and 731 were female, and the mean age was (62.6±17.9) years. Of 696 (33.6%) who died in hospital, 968 (46.8%) were in the MFO<5%L/kg group, 530 (25.6%) were in the MFO 5%-10%L/kg group, and 572 (27.6%) were in the MFO≥10%L/kg group. Deceased patients had significantly higher fluid input than surviving patients during the first 3 days [7 642.0 (2 874.3, 13 639.5) ml vs. 5 738.0 (1 489.0, 7 153.5)ml], and lower fluid output [4 086.0 (1 367.0, 6 354.5) ml vs. 6 130.0 (2 046.0, 11 762.0) ml]. The cumulative survival rates in the three groups gradually decreased with length of ICU stay, and they were 74.9% (725/968) in the MFO<5% L/kg group, 67.7% (359/530) in the MFO 5%-10%L/kg group, and 51.6% (295/572) in the MFO≥10%L/kg group. Compared with the MFO<5%L/kg group, the MFO≥10%L/kg group had a 49% increased risk of inhospital mortality (HR=1.49, 95%CI 1.28-1.73). For each 1% L/kg increase in MFO, the risk of in-hospital mortality increased by 7% (HR=1.07, 95% CI 1.05-1.09). There was a"J-shaped"non-linear association between MFO and in-hospital mortality with a nadir of 4.1% L/kg. Conclusion: Higher and lower optimum fluid balance levels were associated with an increased risk of in-hospital mortality, as reflected by the observed J-shaped non-linear association between fluid overload and inhospital mortality.

Abstract
The intestinal mucosal barrier is one of the important barriers to prevent harmful substances and pathogens from entering the body environment and to maintain intestinal homeostasis. This study investigated the reparative effect and possible mechanism of Tetrastigma hemsleyanum polysaccharides (THP) on ceftriaxone-induced intestinal mucosal damage. Our results suggested that THP repaired the mechanical barrier damage of intestinal mucosa by enhancing the expression of intestinal tight junction proteins, reducing intestinal mucosal permeability and improving the pathological state of intestinal epithelial cells. Intestinal immune and chemical barrier was further restored by THP via the increment of the body's cytokine levels, intestinal SIgA levels, intestinal goblet cell number, intestinal mucin-2 levels, and short-chain fatty acid levels. In addition, THP increased the abundance of probiotic bacteria (such as Lactobacillus), reduced the abundance of harmful bacteria (such as Enterococcus) to repair the intestinal biological barrier, restored intestinal mucosal barrier function, and maintains intestinal homeostasis. The possible mechanisms were related to sphingolipid metabolism, linoleic acid metabolism, and d-glutamine and D-glutamate metabolism. Our results demonstrated the potential therapeutic effect of THP against intestinal flora disorders and intestinal barrier function impairment caused by antibiotics.

Abstract
RATIONALE The polymerized impurities in oxacillin sodium can induce allergic reaction, which can seriously threaten the health of patients. Gel filtration chromatography (GFC) is currently widely used for the analysis of polymerized impurities, but it has drawbacks. To effectively control the polymerized impurities in oxacillin sodium, a high-performance size exclusion chromatography (HPSEC) method and a reversed-phase high performance liquid chromatography (RP-HPLC) method were established to replace the classical GFC method. METHODS By studying the chromatographic behavior of polymerized impurities and small molecular weight impurities in both methods with different chromatographic separation mechanisms, the polymerized impurities in oxacillin sodium were separated and detected effectively. Column-switching two-dimensional liquid chromatography was applied to eluted polymerized impurities from the HPSEC method for oxacillin sodium. Ion trap/time-of-flight mass spectrometry was applied to characterize the structures of polymerized impurities and unknown impurities eluted from the HPSEC/RP-HPLC method for oxacillin sodium. RESULTS The structures of 25 unknown impurities in oxacillin sodium were elucidated based on the high-resolution massn data. Thirteen polymerized impurities were found and characterized. The corresponding relationship of impurities between the two methods was established and the specificity of the two methods was compared. The RP-HPLC method for analysis of the polymerized impurities not only has higher column efficiency and more specificity than the HPSEC method, but also higher sensitivity. CONCLUSIONS The mechanisms of the formation of degradation impurities in oxacillin sodium were studied. The newly established RP-HPLC methods could effectively separate and detect polymerized impurities and unknown impurities in oxacillin sodium. The study of the impurity profile in oxacillin sodium provided a scientific basis for the improvement of official monographs in pharmacopoeias.

Abstract
BACKGROUND The incidence of infections among cancer patients is as high as 23.2-33.2% in China. However, the lack of information and data on the number of antibiotics used by cancer patients is an obstacle to implementing antibiotic management plans. AIM This study aimed to investigate bacterial infections and antibiotic resistance in Chinese cancer patients to provide a reference for the rational use of antibiotics. DESIGN This was a 5-year retrospective study on the antibiotic resistance of cancer patients. METHODS In this 5-year surveillance study, we collected bacterial and antibiotic resistance data from 20 provincial cancer diagnosis and treatment centers and three specialized cancer hospitals in China. We analyzed the resistance of common bacteria to antibiotics, compared to common clinical drug-resistant bacteria, evaluated the evolution of critical drug-resistant bacteria and conducted data analysis. FINDINGS Between 2016 and 2020, 216 219 bacterial strains were clinically isolated. The resistance trend of Escherichia coli and Klebsiella pneumoniae to amikacin, ciprofloxacin, cefotaxime, piperacillin/tazobactam and imipenem was relatively stable and did not significantly increase over time. The resistance of Pseudomonas aeruginosa strains to all antibiotics tested, including imipenem and meropenem, decreased over time. In contrast, the resistance of Acinetobacter baumannii strains to carbapenems increased from 4.7% to 14.7%. Methicillin-resistant Staphylococcus aureus (MRSA) significantly decreased from 65.2% in 2016 to 48.9% in 2020. CONCLUSIONS The bacterial prevalence and antibiotic resistance rates of E. coli, K. pneumoniae, P. aeruginosa, A. baumannii, S. aureus and MRSA were significantly lower than the national average.

Abstract
Objective: To analyze associated factors and adverse pregnancy outcomes of postpartum hemorrhage in the caesarean section of puerperae with different types of placenta previa. Methods: This retrospective research was a case-control study. Puerperae with cesarean section of placenta previa from January 2019 to December 2020 in Women's Hospital, School of Medicine, Zhejiang University were collected and divided into the<1 000 ml control group or ≥1 000 ml postpartum hemorrhage group according to the amount of blood loss during cesarean section. Differences in continuous variables were analyzed by t-test and categorical variables were analyzed by χ2 test. The risk factors of postpartum hemorrhage were analyzed by logistic multivariate regression. Results: A total of 962 puerperae were enrolled with 773 cases in the control group and 189 cases in the postpartum hemorrhage group. The incidence of gestational weeks, gravidity, parity, induced abortion, placental accreta and preoperative hemoglobin<110 g/L was significantly different between two groups in different types of placenta previa (P<0.001). Logistic multivariate regression model analysis showed that the independent risk factors of postpartum hemorrhage in the caesarean section of low-lying placenta included placental accreta (OR=12.713, 95%CI: 4.296-37.625), preoperative hemoglobin<110 g/L (OR=2.377, 95%CI: 1.062-5.321), and prenatal vaginal bleeding (OR=4.244, 95%CI: 1.865-9.656). The independent risk factors of postpartum hemorrhage in the caesarean section of placenta previa included once induced abortion (OR=2.789, 95%CI:1.189-6.544), induced abortion≥2 (OR=2.843, 95%CI:1.101-7.339), placental accreta (OR=6.079, 95%CI:3.697-9.996), HBsAg positive (OR=3.891, 95%CI:1.385-10.929), and placental attachment to the anterior uterine wall (OR=2.307, 95%CI:1.285-4.142). The rate of postpartum hemorrhage and premature delivery in puerperae with placenta previa was higher than that in puerperae with low-lying placenta (P<0.001). Conclusions: The associated factors of postpartum hemorrhage in puerperae with different types of placenta previa are different. Placenta accreta is the common risk factor of postpartum hemorrhage in puerperae with low-lying placenta and placenta previa.

Abstract
OBJECTIVE To observe the changes in systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) during normal pregnancy and establish appropriate reference intervals (RIs) for healthy pregnant women. PATIENTS AND METHODS This retrospective study was conducted from March 2018 to February 2019. Blood samples were collected from healthy pregnant and nonpregnant women. The complete blood count (CBC) parameters were measured, and SII, NLR, LMR, and PLR were calculated. RIs were established using the 2.5th and 97.5th percentile of the distribution. Besides, the differences in CBC parameters between three pregnant trimesters and maternal ages were also compared to assess their influences on each indicator. RESULTS SII and NLR in three pregnant trimesters increased in pregnant women, and the upper limit of SII and NLR in trimester 2 showed the highest value. On the contrary, LMR decreased in all three pregnant trimesters compared with nonpregnant women, and the values of LMR and PLR showed a gradual downward trend along with the trimesters. Besides, RIs of SII, NLR, LMR, and PLR during different trimesters in different age partitions showed that the values of SII, NLR, and PLR increased with age in a general trend, while LMR showed the opposite trend (p < 0.05). CONCLUSIONS The SII, NLR, LMR, and PLR showed dynamic changes during pregnant trimesters. RIs of SII, NLR, LMR, and PLR for healthy pregnant women according to pregnant trimesters and maternal age were established and validated in this study, which will promote the standardization of clinical application.

Abstract
BACKGROUND The Emergency Department Interventions for Frailty (EDIFY) program was developed to deliver early geriatric specialist interventions at the Emergency Department (ED). EDIFY has been successful in reducing acute admissions among older adults. OBJECTIVES We aimed to examine the effectiveness of EDIFY in improving health-related quality-of-life (HRQOL) and length of stay (LOS), and evaluate EDIFY's cost-effectiveness. DESIGN A quasi-experiment study. SETTING The ED of a 1700-bed tertiary hospital. PARTICIPANTS Patients (≥85 years) pending acute hospital admission and screened by the EDIFY team to be potentially suitable for discharge or transfer to low-acuity care areas. INTERVENTION EDIFY versus standard-care. MEASUREMENTS Data on demographics, comorbidities, premorbid function, and frailty status were gathered. HRQOL was measured using EQ-5D-5L over 6 months. We used a crosswalk methodology to compute Singapore-specific index scores from EQ-5D-5L responses and calculated quality-adjusted life-years (QALYs) gained. LOS and bills in Singapore-dollars (SGD) before subsidy from ED attendances (including admissions, if applicable) were obtained. We estimated average programmatic EDIFY cost and performed multiple imputation (MI) for missing data. QALYs gained, LOS and cost were compared. Potential uncertainties were also examined. RESULTS Among 100 participants (EDIFY=43; standard-care=57), 61 provided complete data. For complete cases, there were significant QALYs gained at 3-month (coefficient=0.032, p=0.004) and overall (coefficient=0.096, p=0.002) for EDIFY, whilst treatment cost was similar between-groups. For MI, we observed only overall QALYs gained for EDIFY (coefficient=0.102, p=0.001). EDIFY reduced LOS by 17% (Incident risk ratio=0.83, p=0.015). In a deterministic sensitivity analysis, EDIFY's cost-threshold was SGD$2,500, and main conclusions were consistent in other uncertainty scenarios. Mean bills were: EDIFY=SGD$4562.70; standard-care=SGD$5530.90. EDIFY's average programmatic cost approximated SGD$469.30. CONCLUSIONS This exploratory proof-of-concept study found that EDIFY benefits QALYs and LOS, with equivalent cost, and is potentially cost-effective. The program has now been established as standard-care for older adults attending the ED at our center.

Abstract
Pyrethroid insecticides are ubiquitously detected in environmental media, food, and urine samples. Our previous epidemiological study reported a correlation between increased pyrethroid exposure and delayed pubertal development in Chinese girls. In this study, we further investigated the effects of perinatal exposure to low doses of cypermethrin (CP) on pubertal onset and hypothalamic-pituitary-ovarian axis in the female mice offspring. The treatment of CP with 60 μg/kg/day from gestation day 6 (GD6) to postnatal day 21 (PND21) significantly decreased the time to puberty in the female offspring. Exposure of CP increased the serum levels of gonadotropin-releasing hormone (GnRH) and the expression of GnRH genes in a dose-dependent manner in the female offspring. CP also induced the serum levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as the expression of gonadotropin subunit genes [LHβ, FSHβ, and chorionic gonadotropin α (Cgα)]. Furthermore, CP induced serum estradiol (E2) levels and the expression of steroidogenesis-related genes [steroidogenic acute regulatory (StAR) and Cytochrome p 450, family 11, subfamily A, polypeptide 1 (CYP11A1)] in the ovary. In accordance with the in vivo tests, administration of CP (6.7, 20, and 60 μg/L) stimulated a dose-dependent increase in the synthesis and secretion of the puberty-related hormones in the explants of hypothalamus, pituitary, and ovary. The interference with calcium channels in the ovary may be responsible for CP-induced pubertal onset. Our study provided evidence that perinatal exposure to low doses of CP induced puberty-related hormones and decreased the time to puberty in the female offspring.

Abstract
Objective: To identify clinical subphenotypes of sepsis by clinical variables, and the association between fluid balance (FB) and outcomes in sepsis patients with different subphenotypes. Methods: Data were derived from China Critical Care Sepsis Trial. A total of 2 075 patients were included in the study, with a mean age of (62.5±17.4) years, 1 362 (65.6%) were male, 713 (34.3%) were female. In-hospital mortality was the primary outcome. Clinical variables were entered into the latent profile analysis (LPA) model which was used to identify the subphenotypes of sepsis. Multivariable logistic regression model was used to explore the association of FB on the first 2 days admitted to ICU and in-hospital mortality. Results: Total of 687 (33.1%) patients died in the hospital. Four subphenotypes of sepsis were identified by the PLA model: 1 421 (68.5%) patients were identified as profile 1, which was characterized by the lowest in-hospital mortality (28.3%, 402/1 421) and was considered as the baseline subphenotype; profile 2 was characterized by multiple organ dysfunction(232, 11.2%); profile 3 was characterized by respiratory dysfunction (196, 9.4%) and profile 4 was characterized by kidney injury/failure (226, 10.9%). Profile 2 showed the highest in-hospital mortality (54.3%, 126/232), followed by profile 4 (39.4%, 89/226), profile 3 (35.7%, 70/196). Profile 2 had the highest FB of 68.5(34.7, 89.4)ml/kg on day 1 and decreased rapidly to 29.4(13.6, 49.8) ml/kg on day 2. Multivariable analysis showed that for every 10 ml/kg of FB increased on the first 48 hours admitted to ICU, the risk of in-hospital mortality decreased 14% (OR=0.86, 95%CI: 0.81-0.97) in profile 2, and increased 4% (OR=1.04, 95%CI:1.02-1.07) in profile 4. However, there were no significant association between FB on the fist 2 days admitted to ICU and the risk of in-hospital mortality in profile 1 (OR=1.06, 95%CI: 0.94-1.19)and in profile 3 (OR=0.99, 95%CI: 0.94-1.05). Conclusions: Four subphenotypes of sepsis were identified according to the clinical variables, which showed different characteristics, distributions, outcomes and responses to fluid balance.

Abstract
RATIONALE Reversed-phase, high-performance liquid chromatography (RP-HPLC) and high-performance size exclusion chromatography (HPSEC) methods were developed to effectively separate unknown impurities and polymerized impurities in cefamandole nafate. The liquid chromatography-tandem ion trap/time-of-flight mass spectrometry (LC-IT-TOF-MS) was applied to characterize the structures of the impurities. Ultraviolet (UV) spectrum characteristics and mass spectrum characteristics of △3 -isomer and 7-epimer in cefamandole nafate were studied to distinguish the isomers. METHODS RPLC-IT-TOF-MS was used to characterize the structures of unknown impurities and polymerized impurities eluted from the C18 column. On this basis, the two-dimensional (2D) HPSEC-IT-TOF-MS was used to confirm the structures of polymerized impurities eluted from the TSK-gel G2000SWxl column. Complete fragmentation patterns of impurities were studied and used to obtain information about the structures of the impurities. RESULTS The structures of 19 unknown impurities in cefamandole nafate were elucidated based on the high-resolution MSn data with both positive and negative modes, assisted by the UV spectra and stress testing, of which 2 impurities were polymerized impurities. Cefamandole nafate produced a series of degradation impurities, and another principal component cefamandole acid also produced a series of similar degradation impurities. The disciplines between mass fragmentation pattern/UV spectrum and structure for △3 -isomer and 7-epimer were presented to distinguish their structures. CONCLUSIONS The results of this study provided a scientific basis for the improvement of official monographs in pharmacopoeias to effectively control the impurities and ensure drug safety for the public. This study also revealed the formation mechanisms of degradation impurities in cefamandole nafate, which may guide industry to improve the manufacturing process and storage conditions to reduce the content of impurities in products.

Abstract
Leaf angle (LA) is a critical agronomic trait enhancing grain yield under high-density planting in maize. A number of researches have been conducted in recent years to investigate the quantitative trait loci/genes responsible for LA variation, while only a few genes were identified through map-based cloning. Here we cloned the ZmDWF1 gene, which was previously reported to encode Δ24-sterol reductase in the brassinosteroids (BRs) biosynthesis pathway. Overexpression of ZmDWF1 resulted in enlarged LA, indicating that ZmDWF1 is a positive regulator of LA in maize. To reveal the regulatory framework of ZmDWF1, we conducted RNA-Sequencing and yeast-two hybrid (Y2H) screening analysis. RNA-Sequencing analyzing results indicate ZmDWF1 mainly affected expression level of genes involved in cell wall associated metabolism and hormone metabolism including BR, gibberellin, and auxin. Y2H screening with Bi-FC assay confirmed three proteins (ZmPP2C-1, ZmROF1, and ZmTWD1) interacting with ZmDWF1. We revealed a new regulatory network of ZmDWF1 gene in controlling plant architecture in maize.

Abstract
At the beginning of clinical application, unilateral biportal endoscopy (UBE) was mainly applied to lumbar degenerative diseases, and lumbar disc herniation or lumbar spinal stenosis accounted for the majority. With the improvement of technology and equipment, the range of diseases being treated continues to expand, and the indications are extended to cervical and thoracic spinal decompression, and it can also be used in conjunction with minimally invasive techniques such as percutaneous pedicle screws and oblique lumbar interbody fusion, which plays an important role in lumbar interbody fusion. However, the development of unilateral biportal endoscopic technology is still in its initial stage in China and has not been widely applied. There are still relevant issues that need to be clarified and further studied. Therefore, this paper discusses the technical superiority, the application expansion and the shortcomings of UBE technique and related issues.

Abstract
To investigate the correlation between serum cytomegalovirus (CMV) IgM antibody/viral load and infection-related clinical symptoms in neonates infected with CMV, and provide basis for clinical assessment and monitoring of neonatal CMV infection. A total of 70 neonates with CMV infection admitted to neonatology in Women's Hospital, School of Medicine Zhejiang University, from January 2014 to December 2020 were included in this study. Using real-time quantitative PCR as the diagnostic criteria, congenital cytomegalovirus-infected neonates (n=29) was diagnosed within the first 3 weeks of life, otherwise, it was postnatally acquired cytomegalovirus infection (n=41). The differences in general information and clinical indicators between IgM antibody positive and negative patients were analyzed, combined with the PCR result, the correlation between the IgM/viral load and the occurrence of symptoms were analyzed. T-test and non-parametric test were used to compare the differences of indicators between groups, logistic regression was used for multivariate analysis, and ROC curve was used to evaluate the auxiliary diagnostic value of relevant indicators. In the congenital CMV infection group and the postnatally acquired CMV infection group, viral load and the proportion of symptomatic patients in IgM positive group were significantly higher than IgM negative group (Z=-2.616, P=0.008; 80% vs. 21%, P=0.005) (Z=-2.405, P=0.016; 56% vs. 19%, P=0.025). Logistic regression analysis of the included population showed the risk factors of CMV infection-related symptoms were IgM positive (OR 4.562, 95%CI:1.461-14.246,P=0.009) and viral load (OR 1.728, 95%CI:1.068-2.798,P=0.026). Regressive analysis for single symptom with correction showed IgM antibody positive was associated with hearing dysfunction(OR 3.954, 95%CI:1.066-14.677,P=0.040),the CMV viral load was associated with thrombocytopenia (OR 2.228, 95%CI:1.124-4.413,P=0.022), and brain imaging abnormalities (OR 3.956, 95%CI:1.421-11.011, P=0.008). Receiver operating characteristic (ROC) analysis showed the area under ROC curve of CMV viral load for brain imaging abnormalities was 0.883 (P<0.001), with a sensitivity of 75.0% and specificity of 90.3%. For neonates infected with CMV, the risk of infection-related clinical symptoms and hearing dysfunction may be increased when IgM antibody was positive. Meanwhile, the higher the CMV viral load at diagnosis, the higher the risk of thrombocytopenia and abnormal brain imaging.

Abstract
Tetrastigma hemsleyanum Diels et Gilg is a traditional Chinese herbal medicine with high medicinal value, and antitumor, antioxidant and anti-inflammatory biological activities. However, while several studies have focused on flavonoids in Tetrastigma hemsleyanum tubers, there are few studies on the enhanced immune effect of Tetrastigma hemsleyanum polysaccharides (THP). In this study, we evaluated the antitumor effect of THP in a lung tumor model and explored the mechanism of antitumor activity through intestinal flora. In addition, a cyclophosphamide (CTX)-induced immunosuppression model was used to declare the immunomodulatory effect of THP in the immunosuppressive state induced by antitumor drugs. The results showed that THP increased the content of ileum secreted immunoglobulin A (SIgA) and cecum short-chain fatty acids (SCFAs) and improved microbial community diversity, regulating the relative abundance of dominant microbiota flora from the phylum level to the genus level, and recovering the intestinal microflora disorder caused by tumors. Additionally, THP can increase the organ indices and improve immune organ atrophy. THP can upregulate routine blood counts and stimulate the production of the serum cytokines. THP also promoted the macrophage phagocytic index, NK-cell activation, and complement and immunoglobulin (IgG, IgA, IgM) levels. The detection of Splenic lymphocyte proliferation and T lymphocyte subsets also sideways reflects that THP can restore CTX-induced immune inhibition in mice. In conclusion, this study suggests that THP can effectively achieve the enhanced antitumor effects, regulate gut microbiota and improve the immunosuppression induced by antitumor drugs. Therefore, THP can enhance the immune capacity and provide novel immunomodulatory and antineoplastic adjuvant agents.

Abstract
Nuclear pore complex (NUP) is the main transport channel between cytoplasm and nucleoplasm, which plays an important role in stress response. The function of NUPs was widely reported in yeast and vertebrate but rarely in plants. Here, we identified a nuclear pore complex (ZmNUP58), that is tightly associated with drought and salt tolerance phenotype accompanied with phenotypic and physiological changes under drought and salt stress. The overexpression of ZmNUP58 in maize (Zea mays L.) significantly promotes both chlorophyll content and activities of antioxidant enzymes under drought- and salt-stressed conditions. RNA-Seq analysis showed that ZmNUP58 could regulate the expression of genes related to phytohormone synthesis and signaling, osmotic adjustment substances, antioxidant enzyme system, cell wall biosynthesis, glucose metabolism and aquaporin. The results provide novel insights into the regulatory role of ZmNUP58 in improving drought and salt tolerance through regulating phytohormone and other stress response genes in maize.

Abstract
With the increasing use of antibiotics worldwide, antibiotic monitoring has become a topic of concern. After metabolizing of antibiotics in animals, the metabolites enter the environment through excreta or ingested by the human body via food chain that may exacerbate the emergence of antibiotic resistance and then threaten human's life. This article summarized several analytical methods used for the determination of antibiotics in recent 10 years. Due to the complex matrices and low concentration level of antibiotics in the food samples, a reliable analysis method is required to maximize the recovery rate. Several techniques like solid phase extraction (SPE), dispersive liquid-liquid microextraction (DLLME) and QuEChERS have been frequently used in the pretreatment process for analytes extraction and concentration. After the pretreatment, ultra-high performance liquid chromatography combined with mass spectrometry has been a reliable method for quantitative analysis and is able to determine multiple antibiotics simultaneously. This review also gives an overview about analytical conditions for antibiotics residues in different food samples and their method validation parameters.

Methods: 111 elderly patients with COVID-19 admitted to the Department of Infectious Diseases, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from February 5 to March 3, 2020 were enrolled. According to the severity of disease and liver function condition, they were divided into severe group (n=40), normal group (n=71), abnormal liver function group (n=86) and normal liver function group (n=25). The indexes related to liver function changes [total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and γ-glutamyl transferase (GGT)] and related influencing factors were analyzed. Results: Among 111 cases, 86 (77.5%) had abnormal liver function of varying degrees, and 28 (25.2%) had liver injury. The abnormal rates of TBil, AST, ALP and GGT were significantly higher in the severe group than normal group (P<0.05). There were no significant differences in age, ribavirin, glucocorticoid and the application of lopinavir-ritonavir tablets between the abnormal liver function and the normal group (P>0.05). The proportion of male was significantly higher in the abnormal liver function than normal liver function group (P<0.05). Conclusion: Elderly COVID-19 patients have a higher proportion of abnormal liver function, and patients in the severe group are more likely to have higher level of TB, AST, ALP and GGT. The abnormal liver function may be related to the direct viral infection of the liver and the inflammatory immune response of the body after infection in elderly patients.

Abstract
To effectively control the polymerized impurities in cefmetazole sodium, novel high performance gel filtration chromatography (HPSEC) with TSK-gel G2000SWxl column and RP-HPLC method with C18 column were used in replace of classical gel filtration chromatography with Sephadex G-10 gel. By studying the chromatographic behavior of polymerized impurities in both chromatographic systems with different chromatographic separation principles, the polymerized impurities in cefmetazole sodium were separated and detected effectively. The two-dimensional liquid chromatography tandem ion trap/time-of-flight mass spectrometry (2D LC-IT-TOF MS) was applied to characterize the structures of polymerized impurities eluted from HPSEC method, and liquid chromatography tandem ion trap/time-of-flight mass spectrometry was applied to characterize the structures of polymerized impurities and other unknown impurities eluted from RP-HPLC method. The structures of fourteen unknown impurities in cefmetazole sodium were deduced based on the MS n data, nine of which were polymerized impurities. The corresponding relationship between impurities in the HPSEC method and RP-HPLC method was established, and the specificity of the two methods was evaluated. The RP-HPLC method for analysis of the polymerized impurities has higher column efficiency and specificity than the HPSEC method. The RP-HPLC method is suitable for quality control of the polymerized impurities in cefmetazole sodium. The forming mechanisms of degradation impurities in cefmetazole sodium were also studied.
