Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

Objective To discuss the potential mechanisms by which programmed cell death(PCD)might contribute to the pathogenesis of diabetic kidney disease(DKD).Methods Retrieve the datasets GSE30529 and GSE30122 from the Gene Expression Omnibus database and analyze them to obtain differentially expressed genes(DEGs)associated with DKD.Utilize the Gene Set Enrichment Analysis website,the ferroptosis database,and the autophagy database,along with relevant literature,to identify genes associated with apoptosis,necroptosis,pyroptosis,autophagy,and ferroptosis.Cross-reference these genes with the DKD DEGs to identify PCD-related genes that are differentially expressed in DKD.Perform Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses to explore the biological functions and potential pathways of the core genes.Conduct a protein-protein interaction network analysis to examine the interaction relationships of the target genes,and use the CytoHubba plugin in Cytoscape to screen for Hub genes.Results In the GSE30529 dataset,a total of 460 DEGs were identified,while the GSE30122 dataset yielded 992 DEGs.After merging and removing duplicates,932 DEGs were obtained.By intersecting these DEGs with PCD-related genes,61 apoptosis-related genes,7 necroptosis-related genes,39 pyroptosis-related genes,18 autophagy-related genes,and 16 ferroptosis-related genes associated with DKD were identified.The KEGG analysis results indicated that the DEGs related to apoptosis,necroptosis,pyroptosis,and autophagy in PCD were primarily enriched in pathways associated with diabetic complications,including the AGE-RAGE,IL-17,NF-κB,and TNF signaling pathways.In contrast,DEGs related to ferroptosis were mainly enriched in the fatty acid degradation pathway.GO enrichment analysis revealed that the biological processes of the differentially expressed PCD related genes in DKD were primarily involved in the regulation of signals such as NF-κB-inducing kinase/NF-κB,IL-1,and IL-17.Conclusions Differentially expressed PCD-related genes in DKD are mainly enriched in related signal pathways such as AGE-RAGE,IL-17,NF-κB and TNF,suggesting a critical role of PCD in the pathogenesis of DKD.

Robotic surgery is known as the"third technological revolution"in the field of surgery,and is an important milestone in the development of modern surgery.However,our country's innovative surgical robot industry is still in its early stages,and it is only being utilized in certain surgical fields.To explore the effectiveness of the application of do-mestic surgical robot in oral and maxillofacial surgery,the author successfully completed a case of benign parotid tumor resection with the assistance of a domestic autonomous robot.The operation was successful,facial nerve function was preserved,and postoperative wound healing was good.

Objective:To study the clinicopathological, immunophenotypic and molecular genetic characteristics of nodular fasciitis (NF) in unusual sites.Methods:A total of 50 cases of NF diagnosed between January 2015 and January 2021 were reviewed in the Department of Pathology, Henan Provincial People′s Hospital, and the clinical and pathologic data were analyzed. Among them, 14 cases from unusual sites were included in this study. Immunohistochemical (IHC) staining was used to detect the expression of related proteins, and fluorescence in situ hybridization (FISH) was used to detect the breakage of the USP6 gene.Results:There were seven males and seven females in the 14 NF respectively. The lesions were located in the extremities, perineum, breast, wrist joints, the gap between lumbar vertebra 4/5, and in eight cases there was involvement of unusual tissues (six cases in skeletal muscle, one case in nerve root, and one case was intravascular). The tumor boundary was unclear with infiltrating growth. Spindle-shaped myofibroblasts were arranged in bundles or chaotically, with mild pleomorphic, small nucleoli and various mitotic figures. The tumor stroma showed collagenization to myxoid degeneration with erythrocyte extravasation and infiltration of inflammatory cells. IHC staining showed that the spindle cells expressed SMA focally or partially, and p16 diffusely and strongly. FISH showed that 12 of 14 cases had USP6 gene breakage, and two of them occurred in the intrathoracic skeletal muscle with the red signal amplification of USP6 gene.Conclusions:NF in unusual sites shows similar clinicopathological and genetic characteristics to classic NF, but the tumor mostly has infiltrating borders, non-specific and strong expression of p16, and USP6 red signal amplification. The pathological diagnosis of NF in rare sites should be highly vigilant.

Objective To investigate the effects of lentivirus-mediated RNA interference (RNAi) targeting DNA binding protein A (dbpA) on the proliferation and the biological behavior of colorectal cancer cell line SW620.Methods The experiment was divided into 3 groups:KD group (siRNA-dbpA,lentivirus interference group),CON group (non-specific sequence group) and NC group (blank control group).The lentiviral vector siRNA-dbpA was constructed and verified by PCR and DNA sequencing.SW620 cells were transfected with siRNA-dbpA plasmid,nontargeting siRNA plasmid,or empty plasmid.After 48 h the transfection,the cells were examined for dbpA expression using Western blot.After 72 hrs transfection,flow cytometry was used to detect the cell apoptosis and cell cycle changes.The cell growth inhibition rate was detected by MTT (4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide) assay,and then clone formation was detected,and the ability of SW620 cells to form tumors in vivo after dbpA was silenced was studied in nude mice.Results PCR analysis and DNA sequencing demonstrated that the RNAi sequence targeting dbpA gene was successfully inserted into the lentiviral vector.siRNA-dbpA transfection resulted in reduced expression of dbpA in SW620 cells.After transfection,the apoptosis rate of siRNA-dbpA-transfected cells increased to 26.60％ ± 0.38％,significantly higher than that in cells transfected with the nontargeting plasmid or the empty plasmid 12.54％ ± 0.25％ and 4.46％ ± 0.19％,respectively (F =28.159,P ＜0.01).The growth inhibition test indicate that the OD value of the fifth day in siRNA-dbpA group was 0.194 ±0.037,significantly lower than that in the other two groups 0.814 ±0.043 and 1.625 ±0.061,respectively(F =23.214,P ＜ 0.01).The colony formation number is 37 ± 3,64 ± 5and 175 ± 10 respectively,siRNA-dbpA is significantly higher than that in the other two groups(F =40.254,P ＜ 0.01).After the completion of nude mouse transplantation tumor model,through the detection of tumor volume,KD group (group siRNA-dbpA) tumor volume after 14 d and CON and NC group had obvious difference (F =38.256,P ＜ 0.05),and after 21d is more significant difference in tumor size (F =40.241,P ＜ 0.01),can be clearly observed after 35 d KD group (group siRNA-dbpA) growing tumors had differences with the control group (F =30.257,P ＜ 0.05).Conclusion Lentivirus-mediated RNAi targeting dbpA can effectively suppress the expression of dbpA in colorectal tumor in nude mice,it is proved that dbpA silencing has a significant inhibitory effect on the growth of living tumor cells and decrease the proliferation of the colorectal cells.

OBJECTIVETo investigate the association of serum folate level with the severity of white matter hyperintensity (WMH) and presence of cerebral microbleeds (CMB).

METHODSClinical data of WMH patients from the second affiliated Hospital, Zhejiang University school of Medicine during July 2011 and February 2016 were retrospectively reviewed. According to Fazekas score based on T2-Flair images, patients were classified into mild WMH (0-3) and severe WMH (4-6). The presence of CMB was assessed on susceptibility weighted imaging (SWI). Binary logistic analysis was conducted to identify the independent predictors for severe WMH and the presence of CMB.

RESULTSTwo hundred and twenty eight patients with WMH were included, among whom 149(65.35%)had severe WMH. In patients with high folate (≥ 15.68 nmol/L), low folate (6.8-15.67 nmol/L) and folate deficiency (<6.8 nmol/L), the proportions of severe WMH were 52.88%, 73.33% and 89.47%, respectively. Binary logistic regression analysis revealed that compared with high folate group, severe WMH was more common in groups with low folate (=2.109, 95%:1.112-4.001,<0.05) and folate deficiency (=6.383, 95%:1.168-34.866,<0.05). Eighty-eight(48.09%) of 183 patients receiving SWI scan presented with CMB. Although the subjects with CMB had lower serum folate level than those without CMB(13.42 vs 16.51 nmol/L,<0.01), binary logistic regression analysis did not reveal the independent association between serum folate level and the presence of CMB after adjusting for hyperhomocysteinemia (>0.05).

CONCLUSIONSLower serum folate level is independently associated with severe WMH, but not with the CMB concurrence.

Objective To investigate the expression of DNA binding protein A (dbpA) in patients with colorectal carcinoma of different stages and its significance.Methods Expression of dbpA protein and mRNA in specimens of normal tissues and colorectal cancer were detected by immunohistochemistry,expression of dbpA mRNA and protein of colorectal cancer cell lines SW480,RKO,SW620,DLD-1,HT-29,SW1463 and tissues were detected by immunohistochemistry,RT-PCR and Western blot.Results There was no positive staining dbpA protein and mRNA in normal colorectal tissues.However,dbpA was expressed in epithelial cells of colorectal mucosa [dbpA mRNA:80.0 ％ (48/60),10.0 ％ (6/60);dbpA protein:83.3 ％ (50/60),10.0 ％ (6/60),P ＜ 0.01].And there was no expression in normal colorectal cell,but its expression was high in 6 colorectal cancer cells (P ＜ 0.05).The high expression of dbpA was correlation with the infiltration depth,lymph node metastasis and type of histology (P ＜ 0.05),and had effect in prognosis of colorectal cancer (P ＜ 0.05).Conclusion Elevated dbpA may be related to the pathogenesis and development of colorectal carcinoma,and dbpA may be a prognostic factor of colorectal carcinoma.
