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.

Objective:To observe the clinical effect of comprehensive reconstruction of grades Ⅰ-Ⅱ thumb and finger defects with hallux osteo-onychocutaneous flaps of great toe.Methods:This is a retrospective study. From June 2020 to December 2023, comprehensive reconstruction surgery for Grade Ⅰ-Ⅱ digital defect were performed with hallux osteo-onychocutaneous flaps of great toe for 3 thumbs and 7 fingers in 9 patients in the Department of Hand and Microsurgery of Baoji Third Hospital. Causes of digital injury were: 4 of machine crush, 3 of electric saw cut, 1 of door crush, and 1 of electrical burn. There were 6 grade I digital defects (beyond the nail root) and 4 grade Ⅱ defects (last segment of digit). The defects of the digits were reconstructed by taking references of the shape and structure of the contralateral normal thumbs and fingers. Then the hallux osteo-onychocutaneous flaps of great toe were designed and harvested accordingly from the left and right great toes. Donor sites were covered by skin grafting or local dressing change. One patient was treated in emergency surgery, 6 in sub-emergency surgery and 2 in elective surgery. Integrated perioperative patient management was provided to all of the patients. Postoperative follow-ups were conducted through the visit of outpatient clinic, telephone calls or WeChat interviews. Flap survival, appearance and sensation recovery were evaluated according to the Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association.Results:Vascular insufficiency of 1 digit occurred in surgery, and relieved by local treatment with lidocaine and warm saline. All 10 digits successfully survived, and all donor sites healed spontaneously. The postoperative follow-up period was 10 to 30 months, with an average of 18 months. One transferred nail was found in poor appearance (not flat), the rest of the reconstructed digits were good in appearance and function. The nail, finger print and fine sensation (TPD 5~8 mm), as well as digital flexion, extension, grasping and opposition of the reconstructed digits were all good. According to the Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association, at the last follow-up visit, 5 digits were in excellent, 4 in good and 1 in fair.Conclusion:The comprehensive reconstruction of grades Ⅰ-Ⅱ digital defects with hallux osteo-onychocutaneous flap of great toe is an ideal surgical technique that can reconstruct the nail, finger print and sensation of a digit, with good postoperative function as well as an aesthetic and realistic appearance.

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.

This paper presents an automatic acquisition and analytic procedure of acupuncture manipulation based on optical navigation, aiming at solving the shortcomings of existing acquisition methods of acupuncture manipulation. An acquisition holder installed at the handle tail of filiform needle was designed to display the movement trajectory of the needle during acupuncture delivery by collecting the movement trajectory of holder. The 3-month old male Bama miniature pig was selected as the experimental subject, and 6 points, "Bojian" "Qiangfeng" "Housanli" "Xiaokua" "Huiyang" (BL35) and "Baihui" (GV20), were selected during acupuncture manipulation. The optical navigation system was used to collect the real-time data, and these data were per-processed and analyzed using mean filtering and Fourier transform. The acupuncture procedure was divided into 3 stages, inserting, lifting-thrusting, and twisting. The results showed that the accuracy was 96.3% at lifting-thrusting stage, and that was 100.0% at twisting stage. The decomposition effect of the entire procedure was satisfactory. This study provides a new approach to the quantitative analysis of acupuncture manipulation. In the future, it needs to further optimize the algorithm and expand the sample size so as to improve the accuracy of this analytic technique.

ObjectiveTo explore the quantity-quality transfer process of medicinal materials， decoction pieces and standard decoction of Haliotidis Concha（Haliotis discus hannai） by analyzing the physical phase and compositional changes， so as to provide references for the effective control of its quality. MethodsA total of 20 batches of Haliotidis Concha（H. discus hannai） from different habitats were collected and prepared into corresponding calcined products and standard decoction， and the content of CaCO₃ of the three samples were determined and the extract yield and transfer rate of CaCO₃ were calculated. The changes in elemental composition and their relative contents were investigated by X-ray fluorescence spectrometry（XRF）， X-ray diffraction（XRD） was used to study the changes in the phase compositions of the three samples and to establish their respective XRD specific chromatogram. Fourier transform infrared spectrometry（FTIR） was used to study the changes in the chemical composition and content changes of the three samples and to establish their respective FTIR specific chromatogram， while combining hierarchical cluster analysis（HCA）， principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） to find the common and differential characteristics， in order to explore the quantity-quality transfer relationship in the preparation process of standard decoction of Haliotidis Concha（H. discus hannai）. ResultsThe CaCO₃ contents of the 20 batches of medicinal materials， decoction pieces and standard decoction of Haliotidis Concha（H. discus hannai） were 93.87%-98.95%， 96.02%-99.97% and 38.29%-51.96%， respectively， and the extract yield of standard decoction was 1.71%-2.37%， and the CaCO₃ transfer rate of decoction pieces-standard decoction was 0.68%-1.27%. XRF results showed that the elemental species and their relative contents contained in Haliotidis Concha and its calcined products had a high degree of similarity， and although there was no obvious difference in the elemental species contained in decoction pieces and standard decoction， the difference in the relative contents was obvious， which was mainly reflected in the decrease of the relative content of element Ca and the increase of the relative content of element Na. XRD results showed that Haliotidis Concha mainly contained CaCO₃ of aragonite and calcite， while calcined Haliotidis Concha only contained CaCO₃ of calcite， and standard decoction mainly contained CaCO₃ of calcite and Na₂CO₃ of natrite. FTIR results showed that there were internal vibrations of O-H， C-H， C=O， HCO₃^- and CO₃^2- groups in Haliotidis Concha， while O-H， HCO₃^- and CO₃^2- groups existed in the calcined products and standard decoction. ConclusionThe changes of Haliotidis Concha and calcined Haliotidis Concha are mainly the increase of CaCO₃ content， the transformation of CaCO₃ aragonite crystal form to calcite crystal form and the absence of organic components after calcination， and the changes of calcined products and standard decoction are mainly the decrease of CaCO₃ content and the increase of Na₂CO₃ relative content. The method established in the study is applicable to the quality control of the shellfish medicines-decoction pieces- standard decoction， which provides a new idea for the study of quality control of dispensing granules of shellfish medicines.

BACKGROUND:Exercise is an effective method for preventing and treating osteoporosis,but it is unclear whether its effect on postmenopausal osteoporosis is related to changes in bone autophagy levels. OBJECTIVE:To observe the effects of exercise via cellular autophagy on the morphology and mechanical properties of bone tissue in ovariectomized rats,and to explore the mechanism of exercise on bone mass in ovariectomized rats from the perspective of autophagy. METHODS:A rat model of postmenopausal osteoporosis was established,and a 24-week moderate-intensity exercise was used for intervention.After the experiment,serum estradiol levels were measured by ELISA,and bone mineral density and bone microstructure of the cortical and trabecular bone were detected by micro-CT.The biomechanical indicators of the tibia were tested by a three-point bending test.Autophagosomes were observed by transmission electron microscopy.The expression of LC3 and ATG7 proteins was analyzed by western blot. RESULTS AND CONCLUSION:The serum estradiol level in the ovariectomized group was significantly lower than that of the sham-operation group and ovariectomized+exercise group(P＜0.01).The body mass of rats in each group increased,and the order was the ovariectomized group＞the ovariectomized+exercise group＞the sham-operation group＞the sham-operation+exercise group.The bone mineral density and bone mass of rats in all groups significantly increased(P＜0.01),but the increase in the ovariectomized group was significantly lower than that of the other groups,and the increase in the ovariectomized+exercise group was significantly higher than that of the ovariectomized group.Compared with the sham-operation group,the bone mineral density of the tibial cancellous bone in the sham-operation+exercise group was significantly increased(P＜0.01),while the bone mineral density in the ovariectomized and ovariectomized+exercise groups was significantly decreased(P＜0.01).Compared with the ovariectomized+exercise group,the ovariectomized group showed significantly lower bone volume fraction,number of trabeculae,and bone mineral density of cancellous bone(P＜0.05),extremely significantly lower trabecular thickness(P＜0.01),and significantly higher mean trabecular pattern factor,trabecular separation,and structural model index(P＜0.01).Compared with the ovariectomized group,the LC3-Ⅱ/LC3-I ratio and the relative expression of ATG7 protein significantly increased in the ovariectomized+exercise group(P＜0.05).Compared with the sham-operation and ovariectomized groups,the number of autophagosomes increased in the sham-operation+exercise and ovariectomized+exercise groups,respectively.To conclude,moderate-intensity treadmill exercise can improve the bone microstructure and biomechanical properties of the tibial cancellous bone and increase bone mass in ovariectomized rats by increasing serum estradiol levels and bone autophagy levels.
