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.

Chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH) are both chronic progressive respiratory diseases that cannot be completely cured. COPD is characterized by irreversible airflow limitation, chronic airway inflammation, and gradual decline in lung function, whereas PH is characterized by pulmonary vasoconstriction, remodeling, and infiltration of inflammatory cells. These diseases have similar pathological features, such as vascular hyperplasia, arteriolar contraction, and inflammatory infiltration. Despite these well-documented observations, the exact mechanisms underlying the occurrence and development of COPD and PH remain unclear. Evidence that mitochondrial dynamics imbalance is one major factor in the development of COPD and PH. Mitochondrial dynamics is precisely regulated by mitochondrial fusion proteins and fission proteins. When mitochondrial dynamics equilibrium is disrupted, it causes mitochondrial and even cell morphological dysfunction. Mitochondrial dynamics participates in various pathological processes for heart and lung disease. Mitochondrial dynamics may be different in the early and late stages of COPD and PH. In the early stages of the disease, mitochondrial fusion increases, inhibiting fission, and thereby compensatorily increasing adenosine triphosphate (ATP) production. With the development of the disease, mitochondria decompensation causes excessive fission. Mitochondrial dynamics is involved in the development of COPD and PH in a spatiotemporal manner. Based on this understanding, treatment strategies for mitochondrial dynamics abnormalities may be different at different stages of COPD and PH disease. This article will provide new ideas for the potential treatment of related diseases.

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.

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.
