Traditional Chinese medicine （TCM）， through its multi-target and systematic regulatory effects， has demonstrated unique advantages in the treatment of gastric precancerous lesions （GPL）. At present， TCM theoretical research on GPL is mainly reflected in three aspects， the integration of macroscopic syndrome differentiation， the inflammation-carcinoma transformation mechanism， as well as the systematization and scientization of theoretical inheritance from famous TCM practitioners. High-quality evidence-based research findings serve as the foundation for clinical practice guidelines on GPL， and TCM has gained international academic recognition in the field of GPL prevention and treatment. Research on TCM mechanisms has yielded a series of important outcomes in the aspects of signaling pathways， gene expression regulation， cellular epigenetics， histone modification， and intestinal microecology. It is proposed that future research on GPL should focus on four key directions， establishing multi-omics data， exploring targeted intervention strategies on key regulatory nodes， advancing the standardization process of integrated traditional Chinese and western medicine prevention and treatment technologies， and constructing stratified screening and intervention platforms. The in-depth integration of TCM microcosmic mechanism of action with its macroscopic syndrome differentiation and treatment system， coupled with interdisciplinary research， will provide valuable references for the clinical treatment and scientific research of GPL.

ObjectiveTo explore the mechanism by which Xianglian Huazhuo prescription ameliorates chronic atrophic gastritis （CAG） through regulating the Golgi protein 73 （GP73）/protein kinase R-like endoplasmic reticulum kinase （PERK）/activating transcription factor 4 （ATF4） signaling pathway and modulating endoplasmic reticulum stress （ERS）. MethodA mouse model of CAG was induced by multiple factors， including ranitidine， N-methyl-N′-nitro-N-nitrosoguanidine （MNNG）， and irregular feeding. The CAG mice were randomized into five groups： model， Morodan （2.0 g·kg^-1）， and high-dose， medium-dose， and low-dose （7.6， 3.8， 1.9 g·kg^-1， respectively） Xianglian Huazhuo prescription， with 10 mice in each group. At the same time， 10 mice in normal group were set up. The mice in the Morodan group and the high-dose， medium-dose， and low-dose groups of Xianglian Huazhuo prescription were administrated with corresponding agents by gavage， and those in the normal group and the model group were administrated with an equal volume of normal saline. All the mice were intervened once a day for 60 consecutive days. After the last administration， the overall morphological changes of the gastric tissue were observed. Hematoxylin-eosin （HE） staining and transmission electron microscopy （TEM） were used to evaluate the pathological morphology and the endoplasmic reticulum ultrastructure in the gastric tissue. The serum levels of pepsinogen Ⅰ （PGⅠ）， pepsinogen Ⅱ （PGⅡ）， gastrin-17 （G-17）， and GP73 were determined by enzyme-linked immunosorbent assay （ELISA）. The pepsinogen ratio （PGR， PGⅠ/PGⅡ） was calculated. The protein levels of GP73， PERK， phosphorylated （p）-PERK， glucose-regulated protein 78 （GRP78）， ATF4， CCAAT enhancer-binding protein homologous protein （CHOP）， cysteinyl aspartate-specific protease-12 （Caspase-12）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） were assessed by Western blot. The expression of GRP78 was detected by immunofluorescence （IF） assay， and the location of Bcl-2 and Bax by immunohistochemistry （IHC）. ResultsCompared with the normal group， the model group showed pale gastric mucosa with flattened folds and reduced and loosely arranged gastric mucosal glands， declined serum levels of PGI， PGR， G-17， and GP73 （P<0.01）. downregulated protein levels of GP73， p-PERK， ATF4， GRP78， CHOP， Caspase-12， and Bax in the gastric tissue， and upregulated protein level of Bcl-2 （P<0.01）. Compared with the model group， the Morodan group and each Xianglian Huazhuo prescription group exhibited red gastric mucosa with increased folds， alleviated pathological damage， swelling endoplasmic reticulum， elevated serum levels of PGI， G-17， and GP73 （P<0.05， P<0.01）， and upregulated protein levels of Caspase-12 and Bax and downregulated protein level of Bcl-2 in the gastric tissue （P<0.05， P<0.01）. The Morodan group and the high-dose and medium-dose Xianglian Huazhuo prescription groups exhibited increased serum level of PGR （P<0.05， P<0.01） and upregulated protein levels of GP73， p-PERK， ATF4， GRP78， and CHOP in the gastric tissue （P<0.05， P<0.01）. ConclusionXianglian Huazhuo prescription can activate the GP73/PERK/ATF4 signaling pathway and induce ERS-mediated apoptosis to alleviate the pathological damage of the gastric mucosa， thereby demonstrating a protective effect against CAG in mice.

Objective:To explore a new surgical approach [anteromedial approach of the hip (AMA)] for Pipkin Ⅰ and Ⅱ femoral head fractures through an imaging and anatomical study.Methods:The hip imaging data were collected of the 38 patients who had undergone lower limb CT angiography for open tibiofibular fractures at Department of Orthopaedics, The Sixth People’s Hospital, School of Medicine, Shanghai Jiao Tong University from June 2023 to January 2024. There were 20 males aged (40.9±3.5) years and 18 females aged (41.5±3.3) years. The origins and shapes of the femoral artery and its main branches were observed. The distances between the femoral head and the femoral artery, the medial femoral circumflex artery, and the lateral femoral circumflex artery were measured. Four fresh adult cadavers were collected, including 2 males and 2 females. Their ages of death were 56, 65, 72 and 78 years old, respectively. An incision was made along the axis of the limb at the midpoint of the inguinal ligament at the 4 fresh cadavers. After the femoral head was exposed through the gap between the femoral artery and the femoral nerve, the range of the femoral head exposed was marked.Results:The femoral artery ran along the anteromedial side of the femoral head. The shortest distance between the medial femoral circumflex artery and the femoral head was (13.1±5.7) mm, and the shortest distance between the origin of the lateral femoral circumflex artery and the femoral head (21.6±8.6) mm. On the lateral view of CT angiography, the distance between the femoral artery and the femoral head was (20.6±4.9) mm at the level of the apex of greater trochanter. Gross observation on the cadavers found only small branches of vessels between the femoral artery and the femoral nerve. After the femoral artery and femoral nerve were respectively pulled medially and laterally, the anterior-inferior part of the femoral head was exposed directly by pulling the muscles to open the joint capsule. The exposure range of the femoral head was further expanded through internal and external rotation of the hip joint under traction. The anatomical gap between the femoral artery and the femoral nerve was named the AMA.Conclusion:AMA utilizes the potential gap between the femoral artery and the femoral nerve, providing a new surgical approach for exposure and fixation of Pipkin type Ⅰ and Ⅱ femoral head fractures.

Objective To study the efficacy of hemoperfusion(HP)in series with continuous renal replace-ment therapy(CRRT)integrated combined blood purification under extracorporeal citrate anticoagulation in the treatment of severe hypertriglyceridemic acute pancreatitis(HTG-AP).Methods A total of 62 patients with severe HTG-AP admitted to the Affiliated Hospital of Xuzhou Medical University from June 2022 to May 2024 were selected and randomly divided into control group and observation group,with 31 cases in each group.The control group was treated with conventional medical treatment+HP combined with CRRT staged combined blood purifica-tion treatment,and the observation group was treated with conventional medical treatment+HP in series with CRRT integrated combined blood purification treatment under extracorporeal citrate anticoagulation.The indexes and clinical efficacy before and 7 days after treatment were compared between the two groups.Results The single CRRT time of the observation group was longer than that of the control group,and the frequency of CRRT was less than that of the control group(P<0.05).There were no significant differences in the total CRRT time,single HP time,HP frequency and total HP time between the two groups(P>0.05).The blood routine,inflammatory factors,blood biochemistry and clinical scores of the two groups after treatment were improved compared with those before treatment(P<0.05).After treatment,the hemoglobin(Hb)and platelet count(Plt)of the observation group were higher than those of the control group(P<0.05),and there were no significant differences in other indexes of blood routine,inflammatory factors,blood biochemistry and clinical scores between the two groups(P>0.05).There were no significant differences in clinical indexes,prognosis and complications between the two groups(P>0.05).Conclusions Without affecting the efficacy,HP in series with CRRT integrated combined blood purification under extracorporeal citrate anticoagulation in the treatment of severe HTG-AP can prolong the use time of CRRT blood filter and pipeline,reduce the use of consumables,reduce the risk of bleeding,and avoid multiple catheter removal of HP and CRRT operation separately,and reduce the risk of related infection.It is worthy of clinical application.

Objective To investigate the therapeutic effect of Sheng Mai San mixed Jiawei Sheng Xian Tang on patients with heart failure with reduced ejection fraction(HFrEF)of Qi deficiency blood stasis type,and its impact on the immune inflammatory response of patients.Methods Ninety patients with HFrEF of Qi deficiency blood stasis type were selected and divided into two groups according to the treatment plan.Patients of the conventional group(42 cases)took sacubitril/valsartan sodium tablets orally.Patients of the combined group(48 cases)were treated with Sheng Mai San combined with Jiawei Sheng Xian Tang on the basis of the conventional group,one dose per day,and divided it in two servings used in the morning and evening.The symptoms of the patients were evaluated by using traditional Chinese medicine(TCM)syndrome score before and after the treatment respectively.Echocardiography technology was used to measure the left ventricular end-diastolic diameter(LVEDD)and left ventricular ejection fraction(LVEF).Enzyme-linked immunosorbent assay was used to detect pentaggrin 3(PTX3),tumor necrosis factor-α(TNF-α),galectin-3(Gal-3),interleukin(IL)-8,IL-6,IL-33 and angiotensin Ⅱ(Ang Ⅱ).N-terminal pro-brain natriuretic peptide(NT-proBNP)was detected by immunofluorescence analysis.The therapeutic effect was evaluated based on the symptoms and the New York Heart Association(NYHA)cardiac function classification in the United States.Results After treatment,the levels of TCM syndrome scores,LVEDD,TNF-α,PTX3,IL-8,IL-6,IL-33,NT-proBNP,Gal-3 and AngⅡ decreased in both groups,and those in the combined group were lower than those in the conventional group(P＜0.05).The LVEF increased,and which were higher in the combined group than those of the conventional group(P＜0.05).After the treatment,the total effective rate of the combined group was higher than that of the conventional group(P＜0.05).Conclusion The Sheng Mai San mixed Jiawei Sheng Xian Tang as adjuvant therapy can effectively reduce the levels of immune inflammatory cytokines in HFrEF patients of Qi deficiency blood stasis type,improve their clinical symptoms and enhance therapeutic effect.

ObjectiveTo explore the mechanisms of action of Ganlu Xiaodu Dan in treating viral pneumonia by combining network pharmacology and molecular docking with in vivo experimental validation. MethodsNetwork pharmacology and molecular docking were used to predict the core components， target genes， and major pathways of Ganlu Xiaodu Dan. Molecular docking was then applied to verify the interactions between the core components and key targets. Sixty male C57BL/6 mice were randomly divided into six groups （n = 10 per group）， including blank， model， dexamethasone， and Ganlu Xiaodu Dan low-， medium-， and high-dose groups. The blank and model groups were gavaged with physiological saline （10 mL·kg^-1） every 12 h. The dexamethasone group received intraperitoneal injections of dexamethasone （5 mg·kg^-1）. The low-， medium-， and high-dose groups of Ganlu Xiaodu Dan were gavaged with solutions at concentrations of 7.2， 14.4， and 21.6 g·kg^-1， respectively， every 12 h. Lung wet/dry weight ratio （W/D） was measured. Hematoxylin-eosin （HE） staining was used to observe pathological changes in lung tissue. Enzyme-linked immunosorbent assay （ELISA） was employed to determine the expression levels of tumor necrosis factor-α （TNF-α）， interleukin （IL）-17， and IL-1β in bronchoalveolar lavage fluid （BALF）. Western blot was performed to detect the expression of phosphoinositide 3-kinase （PI3K） and protein kinase B （Akt） in lung tissue for further validation. ResultsTwelve potential active components of Ganlu Xiaodu Dan were identified through network pharmacology. A total of 306 overlapping target genes were obtained between Ganlu Xiaodu Dan and viral pneumonia. PPI network analysis identified the top 20 key targets， and GO and KEGG enrichment analyses revealed the top 20 signaling pathways. An “active component–target–pathway” network was constructed. Molecular docking demonstrated strong affinity between the core components of Ganlu Xiaodu Dan and key targets related to viral pneumonia. In animal experiments， compared with the blank group， the model group showed severe bronchial epithelial damage， disordered alveolar structure， massive inflammatory cell infiltration， widened alveolar septa， and obvious interstitial edema. W/D， levels of IL-1β， TNF-α， and IL-17 in BALF， and protein expression of p-PI3K/PI3K and p-Akt/Akt in lung tissue were all significantly increased （P<0.05）. Compared with the model group， lung injury in the Ganlu Xiaodu Dan groups and the dexamethasone group was alleviated. W/D and TNF-α levels were significantly decreased （P<0.05）. IL-1β and IL-17 levels were significantly reduced in the medium- and high-dose groups and the dexamethasone group， and the protein expression levels of p-PI3K/PI3K and p-Akt/Akt in lung tissue were significantly decreased （P<0.05）. ConclusionGanlu Xiaodu Dan can alleviate lung injury in viral pneumonia by suppressing the inflammatory response， and its mechanism may be related to the inhibition of PI3K/Akt pathway activation.
