Gastric cancer is a common malignant tumor of the digestive tract and can be classified as “fullness of the stomach”， “epigastric pain”， “noise” and other categories in the field of traditional Chinese medicine. Sijunzi decoction is composed of Panax ginseng， Poria cocos， Atractylodes macrocephala， and honey-fried Glycyrrhiza uralensis， and it has the effect of tonifying qi and strengthening the spleen. This article summarizes the active ingredients， mechanism of action， and clinical application research progress of Sijunzi decoction in treating gastric cancer. The results show that the main active ingredients of Sijunzi decoction include ginsenosides， atractylenolide， pachymic acid， glycyrrhizic acid， etc.； Sijunzi decoction and its effective ingredients can play an anti-gastric cancer role by inhibiting the proliferation of gastric cancer cell， inducing apoptosis of gastric cancer cell， enhancing gastric cancer cell chemotherapy sensitivity， and inhibiting invasion and metastasis of gastric cancer cell. In addition， Sijunzi decoction can enhance the efficacy of chemotherapy drugs， strengthen the immune function of the body and lower serum cancer marker levels during the clinical treatment of gastric cancer.

Objective To analyze the current status,hotspots,and trends in the research field of traditional Chinese medicine and pharmacy combined with transcatheter arterial chemoembolization(TACE)for the treatment of hepatocellular carcinoma.Methods The relevant literatures on traditional Chinese medicine and pharmacy combined with TACE treatment for hepatocellular carcinoma collected by China National Knowledge Infrastructure from January 1994 to December 2022,and use CiteSpace 6.1.R6 software to analyze its publication volume,authors,research institutions,and key words.Results This study included a total of 686 articles.The publication volume showed a fluctuating upward trend from 1994 to 2015,but it had decreased since 2016,indicating that further breakthrough research was needed in this field.The communication between authors and research institutions needed to be strengthened,with low levels of cross institutional and cross regional cooperation and uneven geographical distribution.Cooperation should be strengthened.High frequency key words included hepatocellular carcinoma,Chinese materia medica,interventional therapy,therapeutic,etc.,resulting in 9 key word clustering labels.Conclusion Currently,there is a lack of experimental research and related mechanism research,the future research hotspots of traditional Chinese medicine and pharmacy combined with TACE treatment for hepatocellular carcinoma will focus more on traditional Chinese medicine and pharmacy,interventional therapy,clinical observation,and cell apoptosis,which provides new ideas for researchers conducting related research in the future.

BACKGROUND:As a dominant breed pig in southwest China,the southern Yunnan small-ear pig has been widely used as an experimental animal in the basic research of other disciplines,but there are still no reports on its application in anterior cruciate ligament reconstruction. OBJECTIVE:To establish a large animal model of the southern Yunnan small-ear pig with anterior cruciate ligament with autologous Achilles tendon was established. METHODS:Twenty adult female Yunnan small-ear pigs were equally randomized into two groups.In the autologous Achilles tendon group,the right knee anterior cruciate ligament was reconstructed with autologous Achilles tendon as a graft,while in the sham-operated group,a similar operation was performed on the right knee without any treatment of the anterior cruciate ligament.General conditions of each pig were observed and recorded before and 12 months after surgery.Ligaments and grafts were taken for gross observation and MAS scoring.Hematoxylin-eosin staining was performed to observe morphological characteristics of ligaments.The staining and arrangement of type I and type Ⅲ collagen were evaluated by immunohistochemistry.Transmission electron microscopy was used to observe the type,size,diameter,ratio,and distribution of collagen fibers in ligaments. RESULTS AND CONCLUSION:All animals had normal diet and activity,good wound healing,no obvious inflammatory reaction,no local purulent infection,and no significant changes in mental and urinary conditions compared with those before surgery.The reconstructed cruciate ligament of the knee was intact,with no stiffness and normal range of motion.Both the anterior drawer and Lachman tests were negative.Gross observation of the graft:12 months after surgery,the grafts was in good position,with good integrity,obvious tension,ligament color close to the original anterior cruciate ligament,and complete surface synovial coverage.Most of the intraarticular ligaments in the autologous Achilles tendon group were defined as MAS I type and a few were defined as MAS Ⅱ type.In the sham-operated group,the intraarticular ligament was defined as MAS I type.Hematoxylin-eosin staining indicated that,12 months after surgery,collagen fibers in the autologous Achilles tendon group began to appear bundled,isotropic,and uniformly arranged,with more obvious isotropic corrugations,and the nuclei were mainly linear or spindle-shaped,which were similar to those in normal anterior cruciate ligament tissue of the sham-operated group.Immunohistochemistry results indicated that,12 months after surgery,there was a higher expression of type I collagen and significantly less expression of type Ⅲ collagen in the reconstructed anterior cruciate ligament in the autologous Achilles tendon group.The degree of type I and type Ⅲ staining was similar in the two groups.Under the transmission electron microscope,the diameter,arrangement and density of collagen fibers in the reconstructed anterior cruciate ligament of the autologous Achilles tendon group were similar to those of the original anterior cruciate ligament at 12 months after surgery,indicating that the ligament remodeling process had been basically completed in the autologous Achilles tendon group at 12 months after surgery.Through a comprehensive evaluation of animal general conditions,ligament general view,MAS score,hematoxylin-eosin staining,immunohistochemistry,and transmission electron microscopy observation,we successfully established a large animal model of anterior cruciate ligament reconstruction using autogenous Achilles tendon in southern Yunnan small-ear pigs,with good morphological,histological and ultrastructural results.

Objective To investigate the clinical features and prognosis of hepatocellular carcinoma(HCC).Methods Medical records were collected from 850 HCC patients who were admitted to Hubei Provincial Hospital of Traditional Chinese Medicine from December 2014 to May 2022,and their clinical and prognostic features were analyzed.The chi-square test were used for comparison of categorical data between groups;the Kaplan-Meier method was used to calculate survival time and survival rate,and the log-rank test was used for comparison of survival time based on baseline features.Results Among the 850 HCC patients,male patients accounted for 82.6%,and the median age at initial diagnosis was 58.0(49.0,66.0)years,with the highest proportion of patients aged 50-69 years(59.8%).The patients with HBV infection accounted for the highest proportion of 77.4%;at initial diagnosis,49.2%of the patients had portal vein tumor thrombus,and 20.2%of the patients had extrahepatic metastasis,among which pulmonary metastasis accounted for the highest proportion of 44.2%(76/172).The patients with Barcelona Clinic Liver Cancer(BCLC)stage A(0),B,C,and D HCC accounted for 20.4%,22.5%,41.5%,and 15.6%,respectively.There was a significant difference in the distribution of BCLC stages between different groups based on sex(χ2=16.631,P=0.001),age(χ2=24.261,P=0.019),place of residence(χ2=39.776,P＜0.001),presence or absence of viral hepatitis(χ2=8.338,P=0.040),and presence or absence of regular antiviral therapy before initial diagnosis(χ2=26.140,P＜0.001).Follow-up was performed for 489 patients till death,with a median survival time of 19.99 months(95%confidence interval[CI]:14.86-25.12),and the 1-,3-,5-,and 10-year cumulative survival rates were 60.7%,39.9%,29.4%,and 22.7%,respectively.There was a significant difference in survival time between different groups based on age(χ2=13.452,P=0.009),history of viral hepatitis(χ2=6.123,P=0.013),regular antiviral therapy before initial diagnosis(χ2=15.505,P＜0.001),comorbidity with type 2 diabetes(χ2=9.820,P=0.002),the number of tumors(χ2=57.713,P＜0.001),maximum tumor diameter(χ2=41.862,P＜0.001),portal vein tumor thrombus(χ2=293.909,P＜0.001),extrahepatic metastasis at initial diagnosis(χ2=118.329,P＜0.001),BCLC stage(χ2=465.638,P＜0.001),surgical resection(χ2=78.86,P＜0.001),local treatment(χ2=36.216,P＜0.001),immune checkpoint inhibitor treatment and/or anti-tumor angiogenesis therapy(χ2=7.182,P=0.007),traditional Chinese medicine decoction treatment(χ2=30.050,P＜0.001),and comprehensive treatment regimens(χ2=13.221,P=0.004).Progression-free survival(PFS)was recorded for 259 patients(30.5%),with a median PFS of 10.98 months(95%CI:8.54-13.42).Conclusion HCC patients exhibit epidemiological characteristics in terms of sex,age,place of residence,presence or absence of viral hepatitis,regular antiviral therapy before initial diagnosis,tumor characteristics,treatment modality,and prognosis,with a low early detection rate and a short overall survival time,and therefore,it is urgent to perform early screening,early diagnosis,and early treatment.

Stem cell exosome therapy has shown significant potential in treating hair loss, but its safety profile has not been thoroughly studied. This paper reported a case of a 32-year-old female patient who experienced an allergic reaction following adipose-derived stem cell exosomes injection for hair loss treatment at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences in June 2023. Within 24 hours post-injection, the patient developed swelling of the forehead and right postauricular lymph nodes, accompanied by mild pain, and left posterior ear lymph nodes 48 hours later. Ultrasound examination revealed thickening of the local soft tissue and enlarged lymph nodes. The condition was diagnosed as an injection-induced allergic reaction. The symptoms gradually subsided after combined treatment with lidocaine, 5-fluorouracil, and triamcinolone acetonide injections. During a 6-month follow-up period, the patient did not experience any recurrence of allergic reactions, and the therapeutic effects remained stable. This case report highlights the potential risk of allergic reactions associated with stem cell exosome therapy for hair loss, underscoring the need for close monitoring and timely intervention in clinical applications to ensure both safety and efficacy.

Periodontitis is a common chronic inflammatory disease that causes the periodontal bone destruction and may ultimately result in tooth loss.With the progression of periodontitis,the osteoimmunology microenvironment in periodontitis is damaged and leads to the formation of pathological alveolar bone resorption.CD301b+macrophages are specific to the osteoimmunology microenvironment,and are emerging as vital booster for conducting bone regeneration.However,the key upstream targets of CD301b+macrophages and their potential mechanism in periodontitis remain elusive.In this study,we concentrated on the role of Tim4,a latent upstream regulator of CD301b+macrophages.We first demonstrated that the transcription level of Timd4(gene name of Tim4)in CD301b+macrophages was significantly upregulated compared to CD301b-macrophages via high-throughput RNA sequencing.Moreover,several Tim4-related functions such as apoptotic cell clearance,phagocytosis and engulfment were positively regulated by CD301b+macrophages.The single-cell RNA sequencing analysis subsequently discovered that Cd301b and Timd4 were specifically co-expressed in macrophages.The following flow cytometric analysis indicated that Tim4 positive expression rates in total macrophages shared highly synchronized dynamic changes with the proportions of CD301b+macrophages as periodontitis progressed.Furthermore,the deficiency of Tim4 in mice decreased CD301b+macrophages and eventually magnified alveolar bone resorption in periodontitis.Additionally,Tim4 controlled the p38 MAPK signaling pathway to ultimately mediate CD301b+macrophages phenotype.In a word,Tim4 might regulate CD301b+macrophages through p38 MAPK signaling pathway in periodontitis,which provided new insights into periodontitis immunoregulation as well as help to develop innovative therapeutic targets and treatment strategies for periodontitis.

Objective:To explore the medication law of TCM compounds used in the treatment of non-small cell lung cancer (NSCLC).Methods:Clinical literature about TCM compounds in the treatment of NSCLC was retrieved from CNKI, Wanfang Data, PubMed and Web of Science core collection database from January 1st, 2003 to May 1st, 2023. The Python and the ancient and modern medical record cloud platform V2.3.7 were used to analyses frequency statistics and properties, and clustering analysis, factor analysis and association rule analysis were performed.Results:A total of 866 articles were included, with 660 effective TCM compounds, 647 kinds of Chinese materia medica. There were 36 kinds of high-frequency Chinese materia medica, such as Astragali Radix, Atractylodis Macrocephalae Rhizoma and Poria; the efficacy categories of Chinese materia medica mainly included tonics and phlegm resolving cough relieving and asthma relieving drugs. Cluster analysis obtained 4 clusters, factor analysis extracted 11 common factors, and association rule analysis obtained 37 highly supported combinations of Chinese materia medica. The most reliable triple drug combination among them was Astragali Radix-Atractylodis Macrocephalae Rhizoma-Hedyotis diffusa willd, and the double drug combination was Astragali Radix-Ligustri Lucidi Fructus.Conclusion:TCM for the treatment of NSCLC mainly focuses on strengthening the healthy qi, clearing heat, resolving phlegm and detoxifying toxins, supplemented by tonifying qi and activating blood circulation, dispelling dampness and resolving phlegm.

Objective To studyexplore the reversal effect of S-adenosylmethionine(SAM)on chemotherapy resistancechemoresis-tance of pancreatic cancer and explore its related mechanisms.Methods After treatment of human pancreatic cancer resistant cell lines PANC-1/GEM with SAM,the cell proliferation activity of PANC-1/GEM cells and their resistance to gemcitabine(GEM)were ana-lyzed by MTT assay;The the effect of SAM on apoptosis rate of PANC-1/GEM cells was detected by flow cytometry;the change of SAM on the migration activity of drug-resistant cell lines was detected by cell scratch assay;the expression of NEDD4-1 protein in drug-re-sistant cell lines and the changes of NEDD4-1,p-JAK2,p-STAT3 and P-gp protein levels after SAM treatment were detected by Western blot.Results SAM could inhibit the activity of pancreatic cancer PANC-1/GEM resistant cell lines and significantly decreased its resistance to GEM chemotherapy.The IC50 value decreased from 1557.50±201.10nmol/L to 218.39±20.61 nmol/L(P＜0.01);SAM can obviously induced the apoptosis of drug-resistant cell lines and inhibited their migration activity;the expression of NEDD4-1 protein was up-regulated in drug-resistant cell lines,and SAM could inhibit the activation levels of NEDD4-1,p-JAK2,p-STAT3 and P-gp proteins.Conclusion SAM can reduce the chemotherapy resistance of PANC-1/GEM cells to GEM by regulating NEDD4-1 to inhibit the activity of JAK2/STAT3 pathway and regulate the activity of P-gp protein,which provides some experimental evidence for the clinical application of SAM in the treatment of chemotherapy resistance in tumor patients.
