Through data collection and collation combined with bibliometrics， this study conducted a series of textual research on Yanghetang， such as the name and origin， the evolution of prescription composition and modern clinical application. Yanghetang was first recorded in Bencao Yidu of WANG Ang in the Qing dynasty. In addition to Yanghetang， there were 3 bynames of Jiawei Yanghetang， Quanshengji Yanghetang and Zhenjun Yanghetang. Regarding the composition of the formula， a total of 4 versions of Yanghetang were collected. The first version is the 5 medicines version of Cervi Cornus Colla， Rehmanniae Radix Praeparata， Cinnamomi Cortex， Zingiberis Rhizoma and Ephedrae Herba in Bencao Yidu. The second version is the 7 medicines version of Waike Zhengzhi Quanshengji， changing Zingiberis Rhizoma to Zingiberis Rhizoma Praeparatum Carbonisata（ZRPC） and adding Sinapis Semen and Glycyrrhizae Radix et Rhizoma（GRR） on the basis of Bencao Yidu， and most of the Yanghetang is of this version. The third version is the 6 medicines version of Wushi Yifang Huibian， that is， on the basis of Bencao Yidu， Zingiberis Rhizoma is changed into ZRPC， and Sinapis Semen is added. The fourth version is the 6 medicines version in Yifang Jiedu， that is， on the basis of Bencao Yidu， Zingiberis Rhizoma is changed into Zingiberis Rhizoma Praeparatum， and GRR Praeparata cum Melle is added. Regarding the dose of Yanghetang， the doses of the medicines in Waike Zhengzhi Quanshengji was converted into the modern doses as follows：37.3 g of Rehmanniae Radix Praeparata， 1.87 g of Ephedrae Herba， 11.19 g of Cervi Cornus Colla， 7.46 g of Sinapis Semen， 3.73 g of Cinnamomi Cortex， 3.73 g of GRR， and 1.87 g of ZRPC. The origins of the above medicines are consistent with the 2020 edition of Chinese Pharmacopoeia. The processing specification of Rehmanniae Radix Praeparata is steaming method， ZRPC is ginger charcoal， Sinapis Semen is the fried products， and the rest of the medicines are raw products. The decoction method was verified by the decoction method in Chonglou Yuyao， which is similar in the time， and it is recommended that the above medicines should be added with 600 mL of water， decocted to 100 mL， and taken warmly 30 min after meal. For each dose， it is recommended to use 1-3 doses per day according to the doctor's advice in combination with clinical practice. The diseases involved in the ancient applications involved 42 diseases in 11 departments， including orthopedics， dermatology and gynecology， which were dominated by Yin-cold syndrome. However， the diseases involved in modern research also include 148 related diseases in 10 departments， such as orthopedics， obstetrics and gynecology， which is consistent with the ancient books. In recent years， the research hotspots of Yanghetang have focused on more than 10 fields， including osteoblasts， malignant tumors， wound healing， traditional Chinese medicine fumigation and so on， which are widely used. It is suitable for comprehensive research and development because of its rational formula composition， clear origin， processing and decoction method， and wide clinical application.

Excavating the quantitative trait locus (QTL) associated with rice cooking quality, analyzing candidate genes, and improving cooking quality-associated traits of rice varieties by genetic breeding can effectively improve the taste of rice. In this study, we used the indica rice HZ, the japonica rice Nekken2 and 120 recombinant inbred lines (RILs) populations constructed from them as experimental materials to measure the gelatinization temperature (GT), gel consistency (GC) and amylose content (AC) of rice at the maturity stage. We combined the high-density genetic map for QTL mapping. A total of 26 QTLs associated with rice cooking quality (1 QTL associated with GT, 13 QTLs associated with GC, and 12 QTLs associated with AC) were detected, among which the highest likelihood of odd (LOD) value reached 30.24. The expression levels of candidate genes in the localization interval were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR), and it was found that the expression levels of six genes were significantly different from that in parents. It was speculated that the high expression of LOC_Os04g20270 and LOC_Os11g40100 may greatly increase the GC of rice, while the high expression of LOC_Os01g04920 and LOC_Os02g17500 and the low expression of LOC_Os03g02650 and LOC_Os05g25840 may reduce the AC. The results lay a molecular foundation for the cultivation of new high-quality rice varieties, and provide important genetic resources for revealing the molecular regulation mechanism of rice cooking quality.

BACKGROUND:Currently,there have been studies on the regulatory mechanism of lncRNA\miRNA\mRNA co-expression network on the occurrence and development of osteoarthritis.Our research group has screened qualified NONHSAT248596.1 and miR-146a-5p through the database in the previous stage,but the corresponding in vivo experiments to verify the above regulatory mechanisms are still lacking. OBJECTIVE:To explore the role of NONHSAT248596.1 in regulating competitive endogenous RNA of miR-146a-5p in cartilage degeneration mediated by stromal cell derived factor type 1/chemokine receptor 4 axis in vivo. METHODS:The models of osteoarthritis were established in 36 New Zealand rabbits by injecting stromal cell derived factor 1 solution into the knee joint of the right hind limb.According to the random number table method,they were divided into four groups.lncRNA group,miRNA group,ceRNA group and control group were injected with lentivirus vector overexpressing NONHSAT248596.1,lentivirus vector overexpressing miR-146a-5p,lentivirus vector overexpressing miR-146a-5p+NONHSAT248596.1 and empty lentivirus vector into the molded knee joint,respectively.At 4,8 and 12 weeks of modeling,cartilage tissues and subchondral bone tissues of the knee joint were taken for relevant detection. RESULTS AND CONCLUSION:Hematoxylin-eosin staining and safranin fast green staining showed different degrees of degeneration in the four groups.At 4 weeks,the cartilage tissue of the lncRNA group showed swelling of chondrocytes,loss of cell polarity,destruction of extracellular matrix,surface erosion,fracture formation and partial or full layer loss of cartilage tissue.The degree of cartilage injury was gradually aggravated with time.The progression of articular cartilage inflammation in the miRNA group was the slowest among the four groups.qRT-PCR showed that at the same time point,mRNA expression levels of NONHSAT248596.1,chemokine receptor 4,matrix metalloproteinase 3,matrix metalloproteinase 9 and matrix metalloproteinase 13 in cartilage tissue of the lncRNA group were higher than those of the other three groups(P＜0.05).The mRNA expression levels of miR-146a-5p,aggrecan and type Ⅱ collagen were lower than those of the other three groups(P＜0.05).The mRNA expression levels of NONHSAT248596.1,chemokine receptor 4,matrix metalloproteinase 3,matrix metalloproteinase 9 and matrix metalloproteinase 13 in the miRNA group were lower than those in the ceRNA group and control group at 8 and 12 weeks after the model construction(P＜0.05).The mRNA expressions of miR-146a-5p,aggrecan and type Ⅱ collagen were higher than those of the ceRNA group and control group(P＜0.05).Western blot assay showed that at the same time point,the expression levels of aggrecan and type Ⅱ collagen in cartilage tissue of the lncRNA group were always lower than those of the other three groups(P＜0.05).The expression levels of aggrecan and type Ⅱ collagen in cartilage tissue of the miRNA group at 8 and 12 weeks after modeling were higher than those of the ceRNA group and control group(P＜0.05).The results showed that miR-146a-5p,as the target of NONHSAT248596.1,could be inhibited by the effect of its ceRNA.After acting on miR-146a-5p,NONHSAT248596.1 regulates the stromal cell derived factor type 1/chemokine receptor 4 axis to affect the expression of matrix metalloprotein,type Ⅱ collagen,and aggrecan in osteoarthritis chondrocytes,resulting in the degradation of extracellular matrix and the loss of proteoglycan.

BACKGROUND:With the further development of minimally invasive concepts,unicompartmental knee arthroplasty has become an important treatment for osteoarthritis of the knee;however,early postoperative pain adversely affects the recovery process,so effective analgesic measures are necessary.Femoral nerve block and cocktail therapy are common analgesic methods for unicompartmental knee arthroplasty,but there is a lack of studies confirming the analgesic effect and safety of their combined application. OBJECTIVE:To investigate the analgesic effect of cocktail therapy combined with femoral nerve block in unicompartmental knee arthroplasty. METHODS:One hundred patients who received unicompartmental knee arthroplasty from October 2021 to January 2023 were selected as the study subjects.They were divided into a control group(n=50)and a study group(n=50)using a random number table method.The femoral nerve block was used in the control group,while cocktail therapy combined with femoral nerve block was used in the study group during unicompartmental knee arthroplasty.Postoperative analgesia effect,analgesic frequency of dezocine injection within 2 days after surgery,motion range of affected knee joint,KSS function scores,and the occurrence of postoperative adverse reactions were compared between the two groups. RESULTS AND CONCLUSION:(1)Visual analog scale scores in the study group were lower than those in the control group at 12,24,and 48 hours after surgery(P<0.05).(2)The analgesic frequency of dezocine in the study group was less than that in the control group within 2 days after surgery(P<0.05).(3)The motion range in the study group was higher than that in the control group 1 and 3 days after surgery(P<0.05).On day 14 after surgery,there was no significant difference in motion range between the two groups(P>0.05).(4)The knee KSS score in the study group was higher than that in the control group at 2 weeks after surgery(P<0.05).There was no statistically significant difference in knee KSS scores between the two groups from 6 weeks to 6 months after surgery(P>0.05).(5)The difference in the occurrence of adverse reactions within 14 days after surgery was not significant between the two groups(P>0.05).(6)These results show that the use of cocktail therapy combined with femoral nerve block in unicompartmental knee arthroplasty can effectively reduce postoperative pain,improve the analgesic effect,reduce the frequency of analgesic drugs,and improve motion range of the early affected knee joint of patients.

Objective:To investigate the effect and mechanism of the V-set and immunoglobulin domain-containing 4 ( VSIG4 ) gene mutation on the function of microglia in retinitis pigmentosa (RP). Methods:Localization of VSIG4 in the retina was detected by immunofluorescence.HMC3 cells (human microglial cells) were transfected with wild-type (Len-WT) VSIG4 gene, mutant type (Len-Mut) VSIG4 gene and empty vector virus (Len-Cont) and stimulated by the presence or absence of lipopolysaccharide (LPS), then divided into control group, LPS-Len-Mut group, LPS-Len-WT group, LPS-Len-Cont group, Len-Mut group, Len-WT group and Len-Cont group.The mRNA expression levels of the inflammatory factors interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were detected by real-time fluorescence quantitative PCR.Protein expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1), glutathione peroxidase 4 (GPX4), nuclear transcription factor-κB (NF-κB) p65 subunit (P65), and phosphorylated P65 (PP65) were detected by Western blot.Cell phagocytic function was detected by phagocytosis assay.Cell migration ability was detected by cell scratch and transwell migration assay.LPS- stimulated HMC3 cells were co-cultured with 661W cells (mouse retinal photoreceptor cells), and the expression levels of B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X (Bax) proteins of the cells were detected by Western blot.The number of apoptotic cells was determined by apoptosis assay. Results:VSIG4 was localized to microglia in mouse retina.The real-time fluorescence quantitative PCR results showed that compared with LPS-Len-WT group, the relative expression levels of IL-1β and TNF-α mRNA in HMC3 cells were significantly increased in LPS-Len-Mut group (both at P<0.05).The Western blot results showed that compared with LPS- Len-WT group, the protein expression levels of Nrf2, HO-1, and GPX4 in HMC3 cells were significantly reduced in LPS-Len-Mut group, and the PP65/P65 ratio was significantly increased (all at P<0.05).The phagocytic experiment results showed that the phagocytic rates of HMC3 cells in Len-Cont group, LPS-Len-Cont group, LPS-Len-WT group, and LPS-Len-Mut group were (35.67±3.22)%, (63.67±10.07)%, (84.00±3.46)%, and (64.67±2.31)%, respectively, showing a statistically significant difference ( F=59.06, P<0.001).Compared with LPS-Len-WT group, the phagocytic rate of HMC3 cells was significantly reduced in LPS-Len-Mut group ( P<0.05).The results of cell scratch and transwell migration assay showed that compared with LPS-Len-WT group, the migration rate of HMC3 cells at 24 and 48 hours and the number of invading cells per unit area at 24 hours were significantly reduced in LPS-Len-Mut group (all at P<0.05).Compared with LPS-Len-WT group, the expression ratio of Bax/Bcl-2 protein and the number of cell apoptosis were significantly increased in the LPS-Len-Mut group under the co-culture system (both at P<0.05). Conclusions:VSIG4 is localized to mouse retinal microglia.When the VSIG4 gene in RP mutates, HMC3 cells under LPS stimulation exhibit a series of changes, including activation of the NF-κB signaling pathway, decreased activation of the Nrf2/HO-1 signaling pathway, increased secretion of inflammatory cytokines, reduced phagocytic and migratory abilities, and increased cell apoptosis in co-culture systems.

Objective:To screen the host interaction proteins of the severe fever with thrombocytopenia syndrome virus(SFTSV)nonstructural protein(NSs)by immunoprecipitation combined with mass spectrometry analysis,to discuss the functions,subcellular localization,and biological pathways of these interaction proteins,and to provide the basis for clarifying the replication and pathogenic mechanism of SFTSV.Methods:The eukaryotic expression vectors pSFTSV-NSs-Flag(experimental group)and Flag-CMV-3(negative group)were transfected into the human embryonic kidney 293T cells,and contorl group(no treatment)was set up.The lysates of the cells in various groups were collected,and the expression and localization of SFTSV NSs in the host cells were verified by indirect immunofluorescence and Western blotting methods.The protein lysates were treated with protein A/G and immunoprecipitation was used to enrich host proteins binding to NSs.The captured interaction proteins were initially analyzed by silver staining and Coomassie brilliant blue staining to observe the differential protein bands in various groups;liquid chromatography-tandem mass spectrometry was used to obtain the information of protein sequences;the reliable proteins were retained and searched by UniProt database;Gene Ontology(GO)functional enrichment analysis,IPR,eukaryotic orthologous groups(KOGs)functional annotation,Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis,subcellular localization,and transcription factor(TF)functional annotation were used to determine the subcellular structure,gene functions,and biological processes of the interaction proteins.Results:The immunofluorescence results showed that the SFTSV NSs expressed a single specific band at relative molecular mass 33 000 and was localized in the cytoplasm in a granular inclusion body-like manner.The silver staining and Coomassie brilliant blue staining results showed there were significant differential protein bands between experimental group and negative group.The mass spectrometry results identified 46 potential interaction proteins.The GO functional enrichment analysis,KOGs functional annotation,and KEGG signaling pathway enrichment analysis results showed that the biological pathways related to viral translation,cellular metabolism,and protein transport were enriched with a considerable number of proteins.Eight annotated proteins had intermediate filament domains.The highest percentage of subcellular localization was cytoplasmic proteins,consistent with the NSs localization site.The TF functional annotation analysis results showed one protein from the NF-Y family.Conclusion:The interaction proteins play roles in assisting the proper protein folding,participating in the cribosome translation,and forming the cytoskeleton,which may be involved in antiviral replication.These proteins can be used as candidate proteins for further study on the replication mechanism of SFTSV.

Childhood obesity is an escalating public health concern，with its prevalence rising year by year.This condition can lead to a series of metabolic disorders such as type 2 diabetes mellitus，hypertension，hyperlipidemia，and hyperuricemia.While various factors contribute to obesity，genetics plays a significant role，accounting for 40% to 70% of childhood obesity cases.Most of the identified loci harbor genes are involved in pathways affecting neuro-circuits that regulate appetite and satiety，insulin secretion and action，adipogenesis，and lipid metabolism.To date，using genome-wide association studies，over 1 100 obesity susceptibility loci have been identified，with notable examples being leptin，leptin receptor，and melanocortin-4 receptor gene.In this review，the correlation between genetic factors and childhood obesity and the possible mechanisms are elaborated to provide potential directions for its clinical management.

ObjectiveTo investigate the relationship between serum 25(OH)D and gestational diabetes mellitus in the second trimester (GDM), to analyze the interaction effect of key risk factors, so as to provide a basis for clinical personalized vitamin D supplementation. MethodsA total of 266 pregnant women who registered and took regular obstetric check-ups in Shanghai Pudong New Area Health Care Hospital for Women and Children from June to December 2022, were selected as the research subjects. According to the results of oral glucose tolerance test (OGTT), the subjects were divided into the GDM group (131) and control group (135). The level of serum 25(OH)D at the time of OGTT were detected and other clinical indicators were followed up. ResultsThe age, systolic blood pressure in early pregnancy, pre-pregnancy BMI, FPG, OGTT 1-hour and 2-hour glucose, GHb, HOMA-IR, TG, AST, Cr, D-D, FDP and SF at 35 weeks’ gestation of the pregnant women were higher in the GDM group than that of the pregnant women in the normal group, while gestational weight gain and serum 25(OH)D level were significantly lower than that of the pregnant women in the normal group. Serum 25(OH)D was negatively correlated with HOMA-IR and WBS’s, but positively correlated with TG and ALT. Serum 25(OH)D was non-linearly correlated with the risk of GDM in an inverted J-shape, and there was an interaction effect of advanced age, pre-pregnancy obesity and vitamin D deficiency on the risk of GDM. ConclusionVitamin D is non-linearly associated with the risk of GDM. The risk of GDM is significantly reduced when serum 25(OH)D level ≥30 ng∙mL^-1.
