Objective:To explore the acupoint selection law of acupuncture and moxibustion in treating diabetic gastroparesis (DGP) using data mining technology.Methods:The clinical literature on acupuncture and moxibustion treatment for DGP was retrieved from CNKI, Wanfang Data, VIP, SinoMed, PubMed, the Cochrane Library from the establishment of the databases to July 31, 2023. The acupoint prescriptions were extracted to Excel 2016 to establish a database, and the statistics of acupoint frequency, meridian, distribution site and specific acupoint use were collected. SPSS Modeler 18.0 was used to analyze the association rules among acupoints, and SPSS Statistics 25.0 was used for clustering analysis and factor analysis to summarize the acupoint selection law for acupuncture treatment of DGP.Results:Totally 153 articles were included, involving 59 acupoints, with a total frequency of 802 times. The 5 most frequently used acupoints were "Zusanli" (ST 36), "Zhongwan" (CV 12), "Neiguan" (PC 6), "Sanyinjiao" (SP 6), "Pishu" (BL 20). The commonly used meridians were stomach meridian, Conception Vessel and bladder meridian. The involved acupoints were mostly located in the chest-abdomen and lower limbs, and most of them were Wushu acupoints, Mu acupoints, and Xiahe acupoints. The core acupoints group was "Zusanli (ST 36)-Zhongwan (CV 12)-Neiguan (PC 6)-Pishu (BL 20)-Weishu (BL 21)-Sanyinjiao (SP 6)-Tianshu (ST 25)", 24 groups of association rules, 5 effective clusters and 6 factors were obtained.Conclusion:Acupuncture and moxibustion treatment of DGP focuses on both spleen and stomach, treating both symptoms and root causes, and uses methods of combining acupoints such as distant and near matching, combining Mu acupoints, and Xiahe acupoints, and combining of Wushu acupoints and Mu acupoints, to achieve the therapeutic effect of nourishing yin and tonifying qi, dispelling upper abdominal fullness and resolving turbidity, and harmonizing stomach and strengthening spleen.

Ferroptosis is a form of programmed cell death driven by iron-dependent lipid peroxidation and is closely associated with a wide range of biological processes, such as aging, immunity, and cancer. Tumor multidrug resistance, especially resistance to apoptosis, has prompted the urgent search for a new antitumor treatment option. Remarkable progress has been made in the study of the role of ferroptosis in antitumor, especially the interaction with immune cells. Studying immunotherapy based on ferroptosis pathways has become a new direction in antitumor research. In this work, we review the role of ferroptosis in immune cells and antitumor immunotherapy to provide new ideas for ferroptosis-mediated antitumor immunotherapy.

Tbx18,Wt1,and Tcf21 have been identified as epicardial markers during the early embryonic stage.However,the gene markers of mature epicardial cells remain unclear.Single-cell transcriptomic analysis was performed with the Seurat,Monocle,and CellphoneDB packages in R software with standard pro-cedures.Spatial transcriptomics was performed on chilled Visium Tissue Optimization Slides(10x Genomics)and Visium Spatial Gene Expression Slides(10x Genomics).Spatial transcriptomics analysis was performed with Space Ranger software and R software.Immunofluorescence,whole-mount RNA in situ hybridization and X-gal staining were performed to validate the analysis results.Spatial transcriptomics analysis revealed distinct transcriptional profiles and functions between epicardial tissue and non-epicardial tissue.Several gene markers specific to postnatal epicardial tissue were identified,including Msln,C3,Efemp1,and Upk3b.Single-cell transcriptomic analysis revealed that cardiac cells from wildtype mouse hearts(from embryonic day 9.5 to postnatal day 9)could be categorized into six major cell types,which included epicardial cells.Throughout epicardial development,Wt1,Tbx18,and Upk3b were consistently expressed,whereas genes including Msln,C3,and Efemp1 exhibited increased expression during the mature stages of development.Pseudotime analysis further revealed two epicardial cell fates during maturation.Moreover,Upk3b,Msln,Efemp1,and C3 positive epicardial cells were enriched in extracellular matrix signaling.Our results suggested Upk3b,Efemp1,Msln,C3,and other genes were mature epicardium markers.Extracellular matrix signaling was found to play a critical role in the mature epicardium,thus suggesting potential therapeutic targets for heart regeneration in future clinical practice.

Hippo signaling pathway is highly conservative in evolution. MST1/2, LATS1/2, and the effector protein YAP/TAZ are the core members of this signaling pathway in mammalian cells. There have been many studies on YAP/TAZ and its downstream, however, the upstream regulatory factors of the Hippo signaling pathway remain unclear, and become one of the hot research directions of this pathway at present. In addition, Hippo signaling pathway can cross-talk with other signaling pathways such as Wnt and Notch signaling pathways, and plays an important role in controlling organ size, maintaining tissue homeostasis, and promoting tissue repair and regeneration. Abnormal Hippo signaling pathway may lead to the occurrence of a variety of tumors, especially gastrointestinal cancers such as liver cancer, colorectal cancer and gastric cancer. The abnormal expression of its members in gastrointestinal cancers is related to cancer cell proliferation, apoptosis, invasion and migration. Hippo signaling pathway is vital for liver repair and regeneration. Its inactivation will lead to the occurrence of primary liver cancer. The mechanism of YAP in liver cancer mainly depends on TEAD-mediated gene transcription. Hippo signaling pathway is also important for maintaining intestinal homeostasis, and its imbalance can lead to the occurrence and recurrence of colorectal cancer. In primary and metastatic gastric cancer, the expression of YAP/TAZ is significantly up-regulated, but the specific molecular mechanism is unclear. This article summarizes the recent progress on Hippo signaling pathway and its upstream regulatory factors, its roles in the development of gastrointestinal cancers and related molecular mechanisms; and also discusses the future research directions of Hippo signaling pathway.

Objective To evaluate the clinical application of CTA in the bronchial artery embolization treatment.Methods TwentyGeight patients undergoing bronchial artery embolization treatment were divided into two groups.Patients with the examination of bronchial artery CTA before interventional treatment were in group A,others in group B.In group A,according to the distribution of the bronchial artery shown by the CTA,the appropriate catheter was selected for the bronchial artery angiography and embolization.In group B,various catheters for the bronchial artery angiography were performed to find the responsible blood vessels for embolization.The total therapeutic effect, operation time,DSA exposure time and contrast agent were compared between the two groups.Results The pretreatment CTA and DSA contrast were compared and the consistency of the bronchial artery was 90.9%.The effective efficiency of group A was 100%, and the effective rate of group B was 83.3 3%.The time of operation was (6 6.9 ± 1 4.5 )min in group A and (1 3 3.5 ± 1 9.4)min in group B,respectively.DSA exposure time was (2 7.9 ± 1 3.8)min and (5 5.1 ± 1 7.2 )min respectively,and the contrast agent dosage was (89.7±1 7.1)mL and (235.1±1 6.6)mL respectively.The differences between the two groups were statistically significant (P＜0.0 1).Conclusion The bronchial artery CTA examination before interventional treatment is an advantage in increasing the success rate,saving time,and improving efficacy.

Objective To explore the application value of platelet parameters detection in early diagnosis of breast cancer.Methods Platelet parameters of intravenous blood from 103 breast cancer patients and 117 fibroadenoma patients within 24 hours of admission between January 2015 and December 2015 were collected and retrospectively analyzed,including platelet count(PLT),plateletcrit(PCT),mean platelet volume(MPV),mean platelet component concentration(MPC),mean platelet component mass (MPM),platelet distribution width(PDW),and compared with control group of 100 healthy women.The diagnostic efficiency of platelet parameters were assessed using receiver operating characteristic(ROC) curve.Results PLT and PCT in breast cancer group and fibroadenoma group were significantly higher than those in control group(P＜0.01);MPC,PMM and PDW were significantly lower than those in control group(P＜0.01);MPV had no significant statistically difference(P＞0.05).The levels of MPC in breast cancer group were obviously lower than that in fibroadenoma group(P＜0.01).The diagnostic efficiency of MPC in breast cancer had the highest area under curve(AUC=0.835).While the cutoff value of MPC was 249.5 g/L,sensitivity and specificity were 82.5 ％ and 73.6 ％,respectively.Conclusion The detection of platelet parameters,especially MPC,have certain application value in early diagnosis of breast cancer.

OBJECTIVETo analyze the clinical feature and constituent ratio of adult hip fractures in Southwest China.

METHODSThe data of adult inpatients and outpatients with hip fractures treated between January 2010 and December 2011 in 11 hospitals of the Southwest China were collected and analyzed. The data includes gender, age, age distribution and fracture pattern according to AO classification.

RESULTSThere were a total of 2,833 adult hip fractures, including 1,340 (47.30%) males and 1,493 (52.70%) females, with a male-to-female incidence ratio of 1: 1.11 and a mean age of (66±18) years. The highest frequency of hip fractures was seen in the 71 to 85 years age group (42.18%, 1,195/2,833). There were 844 fractures (29.79%) in the young and middle-aged group (16-<60 years) and 1 898 fractures (70.21%) in the geriatric group (≥60 years). Men had a higher rate than women (men: 577 fractures, 68.4%) in the young and middle-aged group, while women had a higher rate than men (women: 1,226 fractures, 61.64%) in the geriatric group, with a significant difference in the sex distribution between the two groups (χ2=214.001, P<0.01). The proportion of intertrochanteric fracture (type 31-A), femoral neck (type 31-B) and femoral head fracture (type 31-C) was 46.59%, 49.74% and 3.67% respectively. The highest frequency of the sub-type in each fracture type was type 31-A2, type 31-B2 and type 31-C2.

CONCLUSIONSWomen have a higher rate than men in Southwest China. Geriatric patients are more than the young and middle-aged patients. The femoral neck fractures, intertrochanteric fractures and femoral head fractures are in descending orders according to the proportion of the three different hip fractures.

Objective To observe the preliminary effects of the treatment for early non-traumatic osteonecrosis of the femoral head with Madopar. Methods Thirty-one patients with 48 hips of early stage (Ficat Ⅰ,Ⅱ) non-traumatic necrosis of the femoral head were treated with oral administration of Madopar since 2002. The disease was associated with consumption of alcohol in 16 cases with 27 hips; use of steroids in 10 cases with 13 hips; both consumption of alcohol and use of steroids in 2 cases with 4 hips; the remaining 3 cases, the condition was idiopathic. According to the criteria of Ficat et al., there were 4 hips in stage Ⅰ; 40 in stage Ⅱa and 4 in stage Ⅱb. Eighteen patients had received madopar for 10-28 months; 13 patients had been receiving the drug until now. Follow-up examinations were made by radiography, MRI and Charnley modified Merle d'Aubigne score. Results All patients were followed up for 12-84 months (average 27.8 months). The clinical symptoms improved in all cases. X-ray films showed that the bone density increased in nearly all the femoral heads, and 68.75%(33/48) of them maintained their shapes. The follow-up MRI showed their necrotic indices had decreased. The rate of clinical satisfaction was 91.67%(44/48), and the successful rate of treatment was 72.92%(35/48), and the collapse rate of early stage necrosis of the femoral head is 27.08%(13/48). Conclusion The preliminary results showed that madopar could prevent or delay collapse of the femoral head in early stage of osteonecrosis.

Objective To study the anti-apoptotic effects of Levodopa on osteonecrosis of the femoral head induced by methylprednisolone (MPS).Methods Forty-four rabbits were randomly divided in to 3 groups.The model group (n=15) was injected with lipopolysaccharide (LPS,10 μg/kg) and then MPS (20 mg/kg) was given 3 times with 24 h interval.The treatment group (n=1 5) was firstly treated by the same methods as the model group,then was administered Levodopa (0.4 g·kg~(-1)·d~(-1)) orally after the last injection of MPS.The control group (n=14) was injected with sodium chloride alone.On the 6th and 8th week after modeling,radiography and MR images were taken in 7 rabbits of each group,specimens taken from the femoral heads were observed by HE stain and TUNEL analysis was made.Blood samples were taken for detection of insulin-like growth factor-1 (IGF-1) on the 8th week.Results On the 6th and 8th week,the average percentage of empty osteocyte lacunae in the treatment group (13.33‰±3.06‰,25.97‰±6.29‰) was significantly lower than that of the model group (21.44‰±4.77‰,33.86‰±8.38‰,P<0.01),and the average apoptosis index in the treatment group (74.93‰±14.32‰,120.67‰±13.13‰) was significantly lower than that of the model group (102.56‰±18.96‰,202.02‰±18.99‰.,P<0.01).On the 8th week,the level of IGF-1 in the treatment group was (14.78±2.37)ng/ml,which was higher than that of the model group obviously (10.12±2.49)ng/ml(P<0.01).Conclusion The Levodopa can decrease apoptosis of osteocytes and effectively prevent the progress of steroid-induced osteonecrosis of the femoral head.
