In this paper, by referring to ancient and modern literature, the textual research of Kochiae Fructus has been conducted to clarify the name, origin, distribution of production areas, quality specification, taste and efficacy, harvesting time, processing and compatibility taboo, so as to provide reference and basis for the development and utilization of related famous classical formulas. According to the investigation, it can be seen that Difuzi was first published in Sheng Nong's Herbal Classic, and has been used as the official name throughout history. It is also known by other names such as Dimai, Dikui, and Luozhou. The mainstream source of Difuzi in materia medica throughout history is the dried ripe fruit of Kochia scoparia, which is consistent throughout history. In the Han dynasty, it was recorded that Kochiae Fructus was produced in Jingzhou(Hubei province), while modern literature records its distribution throughout the country, so it does not have obvious geoherbalism. The harvesting period of Kochiae Fructus is mostly in the late autumn, and the quality is best when it is full, gray green in color, and no impurities. There are two processing methods for its origin:from the Southern and Northern dynasties to the Ming dynasty, it was dried in the shade, and after the founding of the People's Republic of China, it was dried in the sun. There are few records about the processing of Kochiae Fructus, and its clinical application is mostly based on raw products as medicine. The seedlings are harvested in February of the lunar calendar, and the leaves are taken in April and May, processing in the place of origin is shade drying, the processing methods include burning ash and frying frost, pounding juice and wine soaking. For internal use, it is mostly decocted or mashed, while for external use, it is mostly washed with decoction or taken in a soup bath. Throughout history, it has been recorded that Kochiae Fructus is bitter and cold, and is mainly used for treating bladder fever. After the founding of the People's Republic of China, most of the literature classified it as damp-clearing medicine. Since the 1985 edition of Chinese Pharmacopoeia, it has been recorded that Kochiae Fructus has a pungent and bitter taste, and a cold nature. Returning to the kidney and bladder meridians with functions of clearing heat and dampness, dispelling wind and relieving itching. The clinical contraindications are mainly prohibited for those with deficiency and no dampness and heat. Throughout history, it has been recorded that the taste of the seedlings and leaves is bitter and cold for treatment of dysentery. Since modern times, it has been used to regulate the liver, spleen and large intestine meridians, with functions such as clearing heat and detoxifying, and diuresis. Based on the textual research, it is recommended to use the dried ripe fruit of K. scoparia when developing the famous classical formulas containing Kochiae Fructus, and processing shall be carried out according to the original processing requirements. If the original formula does not specify the processing requirements, the raw products is taken into medicine.

In this paper, by referring to ancient and modern literature, the textual research of Cnidii Fructus has been conducted to clarify the name, origin, distribution of production areas, quality specification, nature and flavour, efficacy, harvesting and processing, compatibility taboo and others, so as to provide reference and basis for the development and utilization of the relevant famous classical formulas. After textual research, it can be verified that Cnidii Fructus was first published in Sheng Nong's Herbal Classic, the materia medica of all dynasties was named Shechuangzi, and there are also aliases such as Shesu, Shemi, and Qiangmi. The main source for generations was the dried ripe fruit of Cnidium monnieri, and ancient and modern consistent. From the Eastern Han dynasty to Tang dynasty, the origin of Cnidii Fructus was Zibo, Shandong province. During the Five dynasties, it expanded to Yangzhou in Jiangsu province and Xiangyang in Hubei province, the Song dynasty added Shangqiu in Henan province, and it was considered that Yangzhou, Xiangyang and Shangqiu were its genuine producing areas. It was more widely distributed in Ming and Qing dynasties. After the founding of the People's Republic of China, the origin is clearly distributed throughout the country. For its quality evaluation, generally full grain, gray yellow color, strong aroma is the best. The harvesting period in the past dynasties was mostly the fifth lunar month, and the fruit was collected to remove impurities and dry. The mainstream processing in producing area of the past dynasties was net selection of raw products, mixing and steaming with the juice of Rehmanniae Radix and stir-frying were the mainstream processing methods in the past, there were also stir-frying with honey, stir-frying with salt and rice wine, immersing and steaming with rice wine and other methods. In recent times, it has been used in raw products as medicine. Sheng Nong's Herbal Classic recorded Cnidii Fructus was bitter, Supplementary Records of Famous Physicians recorded its acrid for the first time. It was recorded in the Ming dynasty that its nature was warm, acted on the kidney meridian, and had small toxicity. After the founding of the People's Republic of China, most of the literature classified it as a medicine to attack poison, kill insects and relieve itching with the functions of dispelling pathogenic wind and removing dampness, destroying parasites and elieving itching, warming kidney and activating Yang. Clinical contraindications are mainly contraindicated for people with damp-heat from the lower-jiao or kidney heat. Based on the textual research, it is suggested that when developing the famous classical formulas containing Cnidii Fructus, the source shall be the dried ripe fruit of C. monnieri, and then it shall be processed according to the original formulas. If there is no requirement for processing in the formulas, the raw products can be taken into medicine.

Recent clinical studies have shown that mutation of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene in cancer cells may be associated with immunosuppressive tumor microenvironment (TME) and poor response to immune checkpoint blockade (ICB) therapy. Therefore, efficiently restoring PTEN gene expression in cancer cells is critical to improving the responding rate to ICB therapy. Here, we screened an adeno-associated virus (AAV) capsid for efficient PTEN gene delivery into B16F10 tumor cells. We demonstrated that intratumorally injected AAV6-PTEN successfully restored the tumor cell PTEN gene expression and effectively inhibited tumor progression by inducing tumor cell immunogenic cell death (ICD) and increasing immune cell infiltration. Moreover, we developed an anti-PD-1 loaded phospholipid-based phase separation gel (PPSG), which formed an in situ depot and sustainably release anti-PD-1 drugs within 42 days in vivo. In order to effectively inhibit the recurrence of melanoma, we further applied a triple therapy based on AAV6-PTEN, PPSG@anti-PD-1 and CpG, and showed that this triple therapy strategy enhanced the synergistic antitumor immune effect and also induced robust immune memory, which completely rejected tumor recurrence. We anticipate that this triple therapy could be used as a new tumor combination therapy with stronger immune activation capacity and tumor inhibition efficacy.

ObjectiveAlthough expression of the TEAD1 protein in preadipocytes has been established, its function remains unclear. In this study, we sought to detect transcripts of TEAD1 in chicken and to examine the effects of this protein on the proliferation, migration, apoptosis, and differentiation of immortalized chicken preadipocyte cell lines (ICP1). MethodsThe full-length sequence of the TEAD1 gene was cloned and the two transcripts were subjected to bioinformatics analysis. The subcellsular localization of TEAD1 transcripts was determined based on indirect immunofluorescence. The effects of TEAD1 transcripts overexpression on the proliferation of ICP1 cells were examined by RT-qPCR, CCK-8, and EdU assays; the effects of TEAD1 transcripts on ICP1 cells migration were examined based on the scratch test; and the effects of TEAD1 transcripts overexpression on ICP1 cells apoptosis were analyzed using apoptosis-Hoechst staining and RT-qPCR. The expression of TEAD1 transcripts in different tissues, cells lines, and ICP1 at different periods of differentiation was analyzed by RT-qPCR. The effects of TEAD1 transcripts overexpression on lipid droplet accumulation and adipogenic-related gene expression in ICP1 cells were analyzed based on Oil Red O and BODIPY staining, RT-qPCR, Western blot, and dual-luciferase reporter gene assays. Finally, the content of triglyceride (TG) was measured in TEAD1 overexpressed ICP1 cells. ResultsThe full-length TEAD1 was cloned and two TEAD1 transcripts were identified. The TEAD1-V1 protein was found to be localized primarily in the cell nucleus, whereas the TEAD1-V2 protein is localized in the cell cytoplasm and nucleus. The overexpression of both TEAD1-V1 and TEAD1-V2 significantly inhibited the proliferation of ICP1 cells. Whereas the overexpression of TEAD1-V1 promoted ICP1 cell migration, the overexpression of TEAD1-V2 had no significant effects on ICP1 migration; the overexpression of both TEAD1-V1 and TEAD1-V2 significantly promoted the apoptosis of ICP1 cells. We found that the different transcripts of TEAD1 have similar expression pattern in different tissues and cells lines. During induced preadipocyte differentiation, the expression of these genes initially declined, although subsequently increased. Overexpression of TEAD1-V1 promoted a significant reduction in lipid droplet formation and inhibited C/EBPα expression during the differentiation of ICP1 cells (P<0.05). However, the overexpression of TEAD1-V2 had no significant effect on lipid droplet accumulation or the expression of adipogenic-related proteins (P>0.05). Overexpression of TEAD1-V1 significantly decreased triglyceride content in ICP1 cells (P<0.05), while overexpression of TEAD1-V2 had no effect on triglyceride content in ICP1 cells (P>0.05). ConclusionIn this study, for the first time, identified two TEAD1 transcripts. Overexpressed transcripts TEAD1-V1 and TEAD1-V2 both inhibited the proliferation of chicken preadipocytes and promoted apoptosis of chicken preadipocytes. TEAD1-V1 inhibited the differentiation of preadipocytes and promoted the migration of preadipocytes, while TEAD1-V2 had no effect on the differentiation and migration of preadipocytes.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System(BRICS)were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute(CLSI). WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period,9 035 strains of Gram-negative bacteria were collected from 51 hospitals,of which 7 895(87.4%)were Enterobacteriaceae and 1 140(12.6%)were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli( n=4 510,49.9%), Klebsiella pneumoniae( n=2 340,25.9%), Pseudomonas aeruginosa( n=534,5.9%), Acinetobacter baumannii complex( n=405,4.5%)and Enterobacter cloacae( n=327,3.6%). The ESBLs-producing rates in Escherichia coli, Klebsiella pneumoniae and Proteus spp. were 47.1%(2 095/4 452),21.0%(427/2 033)and 41.1%(58/141),respectively. The prevalence of carbapenem-resistant Escherichia coli(CREC)and carbapenem-resistant Klebsiella pneumoniae(CRKP)were 1.3%(58/4 510)and 13.1%(307/2 340);62.1%(36/58)and 9.8%(30/307)of CREC and CRKP were resistant to ceftazidime/avibactam combination,respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)complex was 59.5%(241/405),while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa(CRPA)was 18.4%(98/534). There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions,with statistically significant differences in the prevalence of CRKP and CRPA( χ2=20.489 and 20.252, P<0.001). The prevalence of CREC,CRKP,CRPA,CRAB,ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals( χ2=11.953,81.183,10.404,5.915,12.415 and 6.459, P<0.01 or <0.05),while the prevalence of CRPA was higher in economically developed regions(per capita GDP ≥ 92 059 Yuan)than that in economically less-developed regions(per capita GDP <92 059 Yuan)( χ2=6.240, P=0.012). Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend,and Escherichia coli is ranked in the top,while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different,and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.
