Huangqintang， with its accurate efficacy， is a classic formula specialized in treating dysentery recommended and promoted by medical experts from successive generations， and it was included in the Catalogue of Ancient Classic Prescriptions （the Second Batch， Han Chinese medicine prescriptions） published by the National Administration of Traditional Chinses Medicine （TCM） in 2023. The method of bibliometrics was applied in this study to conduct textual research on the classic formula Huangqintang and provide a literature reference for the development of modern preparations of Huangqintang. A total of 2 026 pieces of ancient literature were searched with "Huangqintang" as the key word， and 23 pieces of effective data were selected， involving 15 ancient TCM books. The historic evolution， composition， dosage， origin， processing methods， preparation and decocting methods， efficiency， and application of Huangqintang were carefully reviewed. The results showed that Huangqintang was first recorded in the Treatise on Febrile Diseases written by ZHANG Zhongjing. It has the effect of clearing heat， stopping dysentery， regulating the middle， and downbearing counterflow and has become one of the classic formulas widely used in clinical practice. Because of its accurate efficacy， medical experts from later generations have modified it from its original composition. Though many prescriptions have different names， it is the manifestation of physicians' inheritance and development of the thought of ZHANG Zhongjing. Ancient literature showed this prescription had wide indications yet centered on digestive system diseases such as dysentery and abdominal pain. Modern applications of Huangqintang involve digestive， respiratory， ophthalmology and otolaryngology， gynecological， skin， musculoskeletal system， and connective tissue， and this prescription has great potential in treating ulcerative colitis， diarrhea， acute enteritis， and damp-heat dysentery. Through a systematic textual excavation and review of the ancient literature about Huangqintang， the paper has confirmed its key information， so as to provide a scientific basis for the clinical application and new drug development of classic formulas.

Abstract Traditional Chinese medicine (TCM) has demonstrated unique advantages in the prevention and treatment of chronic diseases such as glycolipid metabolism disorder. However, its widespread application has been hindered by the unclear biological essence of TCM syndromes and therapeutic mechanisms. As an emerging interdisciplinary field, phenomics integrates multi-dimensional data including genome, transcriptome, proteome, metabolome, and microbiome. When combined with TCM's holistic philosophy, it forms TCM phenomics, providing novel approaches to reveal the biological connotation of TCM syndromes and the mechanisms of herbal medicine. Taking glycolipid metabolism disorder as an example, this paper explores the application of TCM phenomics in glycolipid metabolism disorder. By analyzing molecular characteristics of related syndromes, TCM phenomics identifies differentially expressed genes, metabolites, and gut microbiota biomarkers to elucidate the dynamic evolution patterns of syndromes. Simultaneously, it deciphers the multi-target regulatory networks of herbal formulas, demonstrating their therapeutic effects through mechanisms including modulation of insulin signaling pathways, improvement of gut microbiota imbalance, and suppression of inflammatory responses. Current challenges include the subjective nature of syndrome diagnosis, insufficient standardization of animal models, and lack of integrated multi-omics analysis. Future research should employ machine learning, multimodal data integration, and cross-omics longitudinal studies to establish quantitative diagnostic systems for syndromes, promote the integration of precision medicine in TCM and western medicine, and accelerate the modernization of TCM.

BACKGROUND:As the incidence of spinal cord injury increases with the years and axon regeneration after spinal cord injury was very difficult.How to promote the recovery from spinal cord injury and improve the transplantation efficiency of stem cells and other therapeutic cells after spinal cord injury has been the focus of clinical and scientific research. OBJECTIVE:To establish the efficient transplantation and replacement of mouse spinal cord microglia in the spinal cord injury model. METHODS:CX3CR1 creER-/+::LSL-BDNF-/+-tdTomato mice,CX3CR1+/GFP mice,β-actin GFP mice and C57 BL/6J wild-type mice at 8-10 weeks of age were selected.According to the requirements of the experiment,they were randomly divided into six groups.(1)Sham operation group:eight C57 BL/6J wild-type mice were used when only the lamina was removed without injury.(2)Spinal cord contusion injury group:eight C57 BL/6J wild-type mice were used.(3)Spinal cord crush injury group:eight C57 BL/6J wild-type mice were used.(4)Conjoined symbiotic spinal cord strike injury group:β-actin GFP mice with green fluorescent blood were surgically stitched together with C57 BL/6J wild-type mice,using eight β-actin GFP mice and eight C57 BL/6J wild-type mice.(5)Mr BMT-X Ray group(using PLX5622 to eliminate the spinal microglia and bone marrow transplantation with X-ray radiation):Bone marrow cells from four CX3CR1 creER-/+::LSL-BDNF-/+-tdTomato mice were extracted and transplanted into eight C57 BL/6J wild-type mice for spinal cord injury modeling.(6)Mr BMT-Busulfan group(using PLX5622 to eliminate the spinal microglia and bone marrow transplantation with Busulfan):Bone marrow cells from four CX3CR1+/GFP mice were transplanted into eight C57 BL/6J wild-type mice.The percentage of cell transplantation replacement in this group was observed,and the spinal cord injury model was not established in this group.The sham operation group,spinal cord contusion injury group and spinal cord crush injury group were sampled by perfusion on day 14 after spinal cord injury.The conjoined symbiotic spinal cord strike injury group was sampled by perfusion on day 7 after spinal cord injury.Mr BMT-X Ray group was sampled by perfusion on day 28 after spinal cord injury.Mr BMT-Busulfan group was sampled by perfusion on day 28 after transplantation.The sampling site was a 1.2 cm long spinal cord with the T10 segment as the center.In the Mr BMT-X Ray group and Mr BMT-Busulfan group,additional mouse brain tissue was retained to see if it would lead to brain transplantation and replacement.The number and proportion of transplanted and replaced cells in the damaged area were measured using transgenic mice,symbiosis and immunofluorescence. RESULTS AND CONCLUSION:Compared with the traditional peripheral blood transplantation(9.8%)of mice in the conjoined symbiotic spinal cord strike injury group,the new transplantation methods,Mr BMT-X Ray and Mr BMT-Busulfan,could greatly improve the proportion of spinal microglia transplantation and replacement,which could reach 84.8%and 95.6%,respectively.The difference was significant(P<0.05).The results showed that Mr BMT-X Ray and Mr BMT-Busulfan could achieve efficient replacement of spinal microglia cells,and could improve the problems of low cell transplantation efficiency,few survival numbers and unclear differentiation of the traditional cell transplantation methods.In addition,Mr BMT-X Ray can only replace the microglia in the spinal cord,while Mr BMT-Busulfan could avoid brain inflammation and injury caused by X-ray radiation transplantation.

BACKGROUND:Although the clinical application of Masquelet technology has achieved extensive success,the research on optimizing all aspects of Masquelet technology is still being carried out.The focus of doctors is to speed up bone healing and shorten bone healing time after bone grafting. OBJECTIVE:To observe the effect of calcium phosphate combined with recombinant human bone morphogenetic protein-2 in repairing tibial infectious bone defects. METHODS:Thirty-one patients with tibial infectious bone defects were selected from The People's Hospital of Jianyang City from June 2017 to June 2022.They were treated with the Masquelet membrane induction technique.During the second stage of operation,they were divided into a control group(n=15)and a study group(n=16)according to different bone graft materials.Patients in the control group were implanted with autologous bone/allogeneic bone particles,and those in the study group were implanted with calcium phosphate combined with recombinant human bone morphogenetic protein-2/autologous bone particles.Six months after the second stage operation,peripheral blood inflammatory indexes such as white blood cell count,C-reactive protein,and erythrocyte sedimentation rate were detected.Imaging bone healing time,bone healing X-ray score,bone defect healing classification,and adjacent joint function were recorded.The presence of nail track infection,implant absorption,pain,and infection in the bone extraction area were observed. RESULTS AND CONCLUSION:(1)White blood cell count,erythrocyte sedimentation rate,and C-reactive protein levels of the two groups 6 months after the second stage operation were significantly lower than those before the first stage operation(P<0.05).There was no significant difference in each index between the two groups(P>0.05).(2)Bone healing time in the study group was shorter than that in the control group(P<0.05).(3)The Samantha X-ray score of the study group 6 months after the second stage operation was higher than that of the control group(P<0.05).The excellent and good rate of bone defect healing and adjacent joint function of the study group was higher than that of the control group(P<0.05).There was no significant difference in the recurrence rate and complication rate between the two groups(P>0.05).(4)These findings indicate that the effect of calcium phosphate combined with recombinant human bone morphogenetic protein-2 during the second stage operation of the Masquelet membrane induction technique in the treatment of tibial infectious bone defect is good and safe.

ObjectiveThis study aimed to evaluate the clinical efficacy of Ruyi Zhenbaowan（RYZBW）in the treatment of initial and early knee osteoarthritis （KOA） through a prospective multicenter，randomized，double-blind，and placebo-parallel controlled trial. MethodFrom October 13^th， 2021 to December 25^th， 2021， 240 KOA subjects meeting the acceptance criteria were enrolled in 15 sub-centers including Wangjing Hospital， Chinese Academy of Chinese Medical Sciences， and they were randomly divided into observation group and control group， with 120 cases in each group. The intervention measures for the observation group were RYZBW + health education， and the intervention measures for the control group were RYZBW placebo + health education. The intervention period in both groups was four weeks， and they were followed up for four weeks after the intervention. The primary outcome measure was the total score of Western Ontario and McMaster University Osteoarthritis Index score （WOMAC score）， and the secondary outcome measures were the response rate of visual scale （VAS） pain score， WOMAC sub item scores （joint pain， joint stiffness， and joint function）， quality of life （SF-12） score， and traditional Chinese medicine （TCM） syndrome score. Result（1） Efficacy evaluation. The marginal model results showed that the observation group was better than the control group in improving the WOMAC total score and WOMAC pain score in the treatment of KOA with RYZBW， and the difference was statistically significant （P<0.05）. There was no significant difference between the two groups in improving VAS score response rate， WOMAC function score， WOMAC stiffness score， SF12-PCS （quality of life-physical health） score， SF12-MCS （quality of life-mental health） score， and TCM syndrome score. （2） Subgroup analysis. ① In terms of VAS score response rate， the response rate of the observation group was higher than that of the control group for subjects with baseline VAS score of （4， 5］， and the difference was statistically significant （P<0.05）. ② In terms of TCM syndrome score， for subjects aged ［56， 60］ and ［61， 65］， the decrease in total TCM syndrome score in the observation group was better than that in the control group， and the difference was statistically significant （P<0.05）. ConclusionTibetan medicine RYZBW has good clinical efficacy in improving WOMAC total score， VAS score response rate， WOMAC pain score， WOMAC function score， and TCM syndrome score for patients with initial and early KOA， which can fill the lack of Tibetan medicine RYZBW in the treatment of KOA and make a demonstration study for the inheritance and development of ethnic medicine.

Objective To investigate the in vitro effect of lncRNA UCA1 on gemcitabine(GEM)resistance of blad-der cancer cell line T24 and its related molecular mechanism.Methods The mRNA expression of UCA1 in T24 cells and in T24/GEM cells was detected by RT-qPCR.The T24/GEM cells were incubated with varying concentra-tions(0.1,1,and 10 μmol/L)of GEM for 48 hrs.LC3 staining microscopy was employed to visualize autophagic puncta,while the expression of autophagy-related proteins was assessed by Western blot.UCA1-shRNA and UCA1-shRNA+pcDNA-Bcl-2 were transferred into T24/GEM cells,the sensitivity of cells to GEM was evaluated by MTT method and flow cytometry;the expressions of p53 and Bcl-2 were detected by Western blot.Results The expres-sion level of UCA1 in T24/GEM cells was significantly higher than that of parental T24 cells(P＜0.05).The con-centration of GEM in the range of 0-10 p.mol/L significantly induced dose-dependent autophagy in T24/GEM cells(P＜0.05).Knockdown of UCA1 enhanced the sensitivity of T24/GEM cells to GEM(P＜0.05),while reducing autophagy(P＜0.05)and down-regulating the expression of p53 and Bcl-2(P＜0.05).Over-expression of Bcl-2 partially reversed the GEM sensitization and autophagy inhibition of UCA1-shRNA in T24/GEM cells(P＜0.05).Conclusions Knockdown of lncRNA UCA1 reduces GEM resistance of T24/GEM cells by inhibiting Bcl-2 mediated autophagy.

Objective:To explore the current status and influencing factors of meaning in life among postoperative lung cancer patients, providing reference and guidance for the development of nursing interventions.Methods:From January to March 2023, convenience sampling was used to select 170 lung cancer patients with surgery in Department of Chest Surgery of the Cancer Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College as the study subject. The patients were surveyed using the General Information Questionnaire, Chinese version of Meaning in Life Questionnaire (C-MLQ), and the Cancer Fatigue Scale (CFS) .Results:The score of meaning in life among postoperative lung cancer patients was (45.71±5.90). Hierarchical linear regression analysis showed that living alone, educational level, and cancer-related fatigue were the influencing factors on the meaning in life among postoperative lung cancer patients ( P<0.05) . Conclusions:The meaning in life of postoperative lung cancer patients is at a moderate level. Medical and nursing staff should focus on patients who live alone and have a low level of education, and can also improve their meaning in life by alleviating cancer-related fatigue.

Objective:To explore the genetic etiology of a child with Cowden syndrome 1 (CS1).Methods:A child who had visited the Ningbo Women and Children's Hospital on August 26, 2022 was selected as the study subject. Clinical information of the child was collected. Genomic DNA was extracted from peripheral blood samples of the child and his family members and subjected to whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing.Results:The child, a 13-year-old boy, had manifested with severe mental retardation, hyperactivity, autistic behavior, sparse and prominent teeth, macrocephaly, and skin freckles on the penis. His mother had presented with multiple papules, hamartomatous polyps, thyroid adenoma and macrocephaly. WES results revealed that the child has harbored a nonsense c. 781C>T (p.Q261*) variant of the PTEN gene, which was inherited from his mother. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.781C>T variant was classified as likely pathogenic (PVS1+ PM2_Supporting). Conclusion:The c. 781C>T variant of the PTEN gene probably underlay the pathogenesis in the child and his mother. Above finding has facilitated genetic counseling for this family.

Objective:To explore the clinical characteristics and genetic etiology of four children with Phelan-McDermid syndrome (PMS).Methods:Four children who had visited the Affiliated Women and Children′s Hospital of Ningbo University between June 2, 2022 and May 8, 2023 were selected as the study subjects. Clinical data of the children were collected. Genomic DNA was extracted from peripheral blood samples of the children and their parents and subjected to whole exome sequencing (WES). Candidate variants were verified by Sanger sequencing and quantitative PCR (q-PCR) analysis. This study was approved by the Medical Ethics Committee of the Affiliated Women and Children′s Hospital of Ningbo University (Ethics No. EC2020-048).Results:All children had presented with speech and language delays and intellectual disability. Children 3 and 4 also presented with autistic behaviors. WES showed that the children 1 and 2 had respectively carried a heterozygous c.731T>C (p.Leu244Pro) and a c.2782_2851del (p.Gly928ArgfsTer4) variant of the SHANK3 gene. Sanger sequencing confirmed that their parents did not carry the same variant, suggesting that they were de novo in origin. Children 3 and 4 had respectively harbored a 121 kb and 52.02 kb heterozygous deletion at chromosome 22q13.33, which had both encompassed the SHANK3 and ACR genes mapped to 22q13.33. q-PCR results showed that the deletion of SHANK3 and ACR genes were de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics, the c. 731T>C and c. 2782_2851del variants were predicted to be likely pathogenic (PS2+ PM2_Supporting+ PP3) and pathogenic (PVS1+ PM2_Supporting+ PS2_Supporting), respectively. Furthermore, the 52.02 kb and 121 kb heterozygous deletions in 22q13.33 were both predicted to be pathogenic (2D+ 4C, 1.05 in score; 2D+ 4C, 1 in score). Conclusion:The four children were all diagnosed with PMS by genetic testing. Above finding has enriched the phenotypic and mutational spectrum of PMS, and provided a basis for clinical diagnosis and genetic counseling for their families.
