Varicocele is a common disease of the male reproductive system, and the pampiniform plexus in the spermatic cord manifests abnormal dilatation, extension, and circuity, which is a vasculopathy. In this article, we believe that the relevance of the essence chamber collaterals to the spermatic vein in terms of anatomical morphology and physiological function is high and that when pathogenic qi invades the essence chamber, the qi and collaterals of the essence chamber are out of harmony, the fluid collaterals are impassable, and the blood collaterals are obstrcuted, and the essence chamber collaterals are blockaded with several pathological products, and even intermingled phlegm and blood stasis in the blood collaterals and form vascular clusters, resulting in the formation and development of varicocele. Based on this, this article proposes the core treatment principle of healing, harmonizing, activating, and dredging the collaterals, with the basic treatment method of nourishing qi and harmonizing collaterals, activating blood collaterals, and dredging blood stasis to, respectively treat degree Ⅰ, Ⅱ, and Ⅲ varicocele, aiming to prevent the change of the varicocele, dredge the curvature of the varicocele, and dissipate the knots of the varicocele. The proposal of essence chamber collaterals is of great significance to understanding the common law and pathological aspects of the occurrence and development of essence collateral and vascular lesions from the perspective of integrated traditional Chinese and Western medicine.

Objective: To develop a non-invasive predictive model for coronary artery stenosis severity based on adaptive multi-modal integration of traditional Chinese and western medicine data. Methods: Clinical indicators, echocardiographic data, traditional Chinese medicine (TCM) tongue manifestations, and facial features were collected from patients who underwent coronary computed tomography angiography (CTA) in the Cardiac Care Unit (CCU) of Shanghai Tenth People's Hospital between May 1, 2023 and May 1, 2024. An adaptive weighted multi-modal data fusion (AWMDF) model based on deep learning was constructed to predict the severity of coronary artery stenosis. The model was evaluated using metrics including accuracy, precision, recall, F1 score, and the area under the receiver operating characteristic (ROC) curve (AUC). Further performance assessment was conducted through comparisons with six ensemble machine learning methods, data ablation, model component ablation, and various decision-level fusion strategies. Results: A total of 158 patients were included in the study. The AWMDF model achieved excellent predictive performance (AUC = 0.973, accuracy = 0.937, precision = 0.937, recall = 0.929, and F1 score = 0.933). Compared with model ablation, data ablation experiments, and various traditional machine learning models, the AWMDF model demonstrated superior performance. Moreover, the adaptive weighting strategy outperformed alternative approaches, including simple weighting, averaging, voting, and fixed-weight schemes. Conclusion The AWMDF model demonstrates potential clinical value in the non-invasive prediction of coronary artery disease and could serve as a tool for clinical decision support.

Methods: From September 3, 2018, to March 23, 2024, participants with essential hypertension (receiving antihypertensive medication treatment, hypertension group) and normal blood pressure (control group) were recruited from the Cardiology Department of Shanghai Hospital of Traditional Chinese Medicine, the Coronary Care Unit of Shanghai Tenth People's Hospital, the Physical Examination Center of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and the Gaohang Community Health Service Center. This study employed the propensity score matching (PSM) method to reduce study participants selection bias. Spectral information in the facial visible light spectrum of the subjects was collected using a flame spectrometer, and the spectral chromaticity values were calculated using the equal-interval wavelength method. The study analyzed the differences in spectral reflectance across various facial regions, including the entire face, forehead, glabella, nose, jaw, left and right zygomatic regions, left and right cheek regions as well as differences in parameters within the Lab color space between the two subject groups. Feature selection was conducted using least absolute shrinkage and selection operator (LASSO) regression, followed by the application of various machine learning algorithms, including logistic regression (LR), support vector machine (SVM), random forest (RF), Naïve Bayes (NB), and eXtreme Gradient Boosting (XGB). The reduced-dimensional dataset was split in a 7 : 3 ratio to establish a classification and assessment model for facial coloration related to primary hypertension. Additionally, model fusion techniques were applied to enhance the predictive power. The performance of the models was evaluated using metrics including the area under the curve (AUC) and accuracy. Shapley Additive exPlanations (SHAP) was used to interpret the outcomes of the models. Results: A total of 114 participants were included in both hypertension and control groups. Reflectance analysis across the entire face and eight predefined areas revealed that the hypertensive group exhibited significantly higher reflectance of corresponding color light in the blue-violet region (P < 0.05) and a lower reflectance in the red region (P < 0.05) compared with control group. Analysis of Lab color space parameters across the entire face and eight predefined areas showed that hypertensive group had significantly lower a and b values than control group (P < 0.05). LASSO regression analysis identified a total of 18 facial color features that were highly correlated with hypertension, including the a values of the chin and the right cheek, the reflectance at 380 nm and at 780 nm of the forehead. The results of the multi-model classification showed that the RF classification model was the most effective, with an AUC of 0.74 and an accuracy of 0.77. The combined model of RF + LR + SVM outperformed a single model in their classification performance, achieving an AUC of 0.80 and an accuracy of 0.76. SHAP model visualization results indicated that the top three contributors to ideal prediction results based on the characteristics from the facial spectrum were the reflectance at 380 nm across the entire face and of the nose as well as the a value of the chin. Conclusion Within the same age group, patients with essential hypertension exhibited significant and regular changes in facial color and facial spectral reflectance parameters after the administration of antihypertensive drugs. Furthermore, facial reflectance indicators, such as the overall reflectance at 380 nm and the a value of the chin, could offer valuable references for clinically assessing the drug efficacy and health status of patients with essential hypertension.

Male infertility,a common condition in andrology,falls under the category of"no son"in traditional Chinese medicine(TCM).Unhealthy eating habits and excessive sexual activity,prevalent due to improved living standards,have contributed to the increasing incidence of male infertility.YE Tianshi proposed the theory of"maintaining with the sweet and restoring the body fluids",which emphasizes the importance of ample body fluid for the nourishment of the male essence chamber.Sufficient body fluid is crucial for normal sperm generation.In TCM,the primary pathogenesis of male infertility involves the loss of body fluids and insufficiency of yin essence.Sweet Chinese herbal medicinal is recommended as it nourishes yin,enriches essence,and replenishes male reproductive essence without producing phlegm and dampness.Therefore,when treating male infertility,attention should be given to the use of sweet Chinese herbal medicinal,adhering to the principle of"abundant body fluids nourish kidney yin,and abundant kidney yin supports semen production".Therapies such as purging fire to preserve body fluids with Zengye Decoction,nourishing yin to enrich essence with Guilu Erxian Decoction,benefiting qi to promote fluid production with Buzhong Yiqi Decoction,and warming yang and transporting fluids with Xianfu Shezi Decoction should be considered.Medication and dosage adjustments should be made based on the specific etiology,pathology,and related symptoms to improve the quality of male sperm and enhance the chances of conception.

The study aimed to investigate the expression of ITGB1 in gastric cancer tissues and its impact on the efficacy of immunotherapy,and to find a new biomarker for prognosis assessment and prediction of immunotherapy response in gastric cancer.By utilizing bioinformatics methods to analyze the transcriptomic data,clinical pathological characteristics,and survival information of gastric cancer patients in the Cancer Genome Atlas(TCGA)database,this study evaluates the expression of ITGB1 in gastric cancer and its correlation with clinical features.Furthermore,an in-depth analysis was conducted for evaluating the relationship of ITGB1 expression with immune infiltration,immune checkpoint-related genes,immune subtypes and immunotherapy response.Data showed that high ITGB1 expression in gastric cancer tissues is associated with later T stage,lower survival rates,and lower overall survival.Analysis of immune infiltration scores showed the score for CD4+T cells,CD8+T cells,neutrophils,macrophages and dendritic cells were higher in the high ITGB1 expression group.Additionally,the levels of immune checkpoint-related genes such as SIGLEC15,TIGIT,CD274,HAVCR2,CTLA4 and PDCD1LG2 were elevated in the high ITGB1 expression group,and the expression of ITGB1 was positively correlated with the expression of immune checkpoint-related genes including SIGLEC15,TIGIT,CD274,HAVCR2,CTLA4,LAG3 and PDCD1LG2.Analysis based on the data from the TISIDB database revealed differential expression of ITGB1 in various immune subtypes of gastric cancer,with significantly higher expression levels in the C6 subtype(TGF-β dominant type).The TIDE algorithm indicated a high score for the group with high ITGB1 expression,suggesting poor efficacy of immune checkpoint blockade therapy.To sum up,we find that high expression of ITGB1 in gastric cancer tissues is a poor prognostic indicator for gastric cancer patients,thus ITGB1 may serve as a potential biomarker for assessing prognosis and predicting the efficacy of immunotherapy in gastric cancer.

Objective:To explore the clinicopathological characteristics and prognosis of pancreatic gastrointestinal interstitial tumors(pGISTs).Methods:Three cases of pGISTs diagnosed in the Affiliated Tumor Hospital of Guangxi Medical University from August 2015 to October 2019 were analyzed retrospectively. Relevant literatures at home and abroad were searched and reviewed through PubMed, China knowledge Network, Wanfang and VIP databases. The sex, age, tumor size, tumor location, cystic or solid tumor, mode of treatment, mitosis, gene mutation, survival status and survival time were recorded, and the correlation between tumor cystic-solid characteristics and clinicopathological parameters was analyzed. Kaplan-Meier′s method was used to calculate the overall survival (OS) rate and disease-free survival (DFS) rate. Univariate and multivariate Cox regression models were used to analyze the independent risk factors affecting the prognosis of pGISTs.Results:In this group, 3 cases were combined with 71 cases reported in the literature, and a total of 74 cases of pGISTs were included. Among them, 36 cases were male and 38 were female, the age of onset was 55(19-84) years, and the diameter of the tumor was 8 cm(2-35 cm). The tumor location of 71 patients was recorded by literature; 30 cases (42.3%) were located in the head of the pancreas. The solid-cystic characteristics of tumor in 63 patients were recorded by literature, and 33 cases (52.4%) were solid. The mode of treatment of 74 patients was recorded, and 60 cases (81.1%) underwent radical resection. The mitosis figures of 59 patients were recorded, and 33 cases (55.9%) were <5/50 high power field of vision (HPF). The gene mutation of 14 patients was recorded, and 11 cases (78.6%) were c-kit exon gene mutation. Correlation analysis showed that the cystic-solid characteristics of the tumor were significantly correlated with tumor location, tumor diameter and mitosis figures, but not with age, sex, histological type, Ki-67 index and modification National Institutes of Health(mNIH) classification. The 5-year OS rate of 51 patients after radical resection was 88.8%, and the 5-year DFS rate was 60.3%. The 1-year OS rate of patients receiving palliative treatment was 51.9%, and the 1-year fatality rate was 33.3%. Univariate Cox regression analysis showed that male ( P=0.083), mitosis figures >5/50 HPF ( P=0.008)and CD 34 negative ( P=0.055)were risk factors for postoperative recurrence of pGISTs, while multivariate Cox regression analysis showed that mitosis figures >5/50 HPF ( P=0.023)was an independent risk factor for the prognosis of pGISTs. Kaplan-Meier survival analysis showed that patients with mitosis figures ≤5/50 HPF had a higher survival rate ( P=0.0003), but there was no significant difference on prognosis between patients with 10/50 HPF and >10/50 HPF( P=0.3075). Conclusions:pGISTs usually occured in the head of pancreas, and the tumor volume was usually found to be large. The main treatment was radical operation, and the main mutation type was exon mutation of c-kit gene. Nuclear fission image figures >5/50HPF was an independent risk factor for postoperative recurrence.

Objective:To synthesize 177Lu-prostate-specific membrane antigen (PSMA)-617 with domestic 177Lu (made in China), and explore its optimal labeling condition, biodistribution, stability, and safety. Methods:177Lu-PSMA-617 was prepared with domestic 177Lu by a manual method. The optimal labeling condition, radiochemical purity, stability ( in vivo and in vitro), lipid-water partition coefficient, and plasma protein binding rate were determined. The uptake rate of 177Lu-PSMA-617 was evaluated by using 22RV1 cells. Biodistribution and SPECT/CT imaging were performed on normal mice with imported 177Lu-PSMA-617 as control group. The blood routine test was performed to evaluate the safety. Results:The best labeling result of domestic 177Lu-PSMA-617 can be obtained under the following conditions: pH=4.5, 100 ℃ for 30 min. And the radiochemical purity was ≥99%. The product was stable in vivo and in vitro, with the radiochemical purity >95% in 72 h. The plasma protein binding rate was (35.3±5.3)%, the lipid-water partition coefficient was -2.27±0.06, and the specific uptake rate of domestic 177Lu-PSMA-617 by 22RV1 cells reached the highest in 1 h ((7.58±0.84)%), which was slightly lower than the imported 177Lu-PSMA-617 ((7.86±0.96)%), but there was no significant difference between them ( t=-0.439, P>0.05). The distribution and SPECT/CT imaging of normal mice showed that domestic and imported 177Lu-PSMA-617 in blood were cleared quite fast, and both of them were excreted mainly through the kidneys. No obvious adverse reactions were found in the toxicity test of domestic and imported 177Lu-PSMA-617. There was no obvious abnormality in blood routine and liver and kidney metabolism. Conclusion:The domestic 177Lu-PSMA-617 has many advantages, such as qualified quality control, good biological properties and safety, which support its potential application value in diagnosis of prostatic neoplasms.

Purpose: Microtubule-associated protein 1 light chain 3B (LC3B) serves as a key component of autophagy,which is associated with the progression of carcinoma. Yet, it is still unclear whetherLC3B is also an independent risk factor for intrahepatic cholangiocarcinoma (ICC). We aimto explore the predictive value of LC3B on prognosis of ICC, and to establish a novel andavailable nomogram to predict relapse-free survival (RFS) and overall survival (OS) for thesepatients after curative-intent hepatectomy. Materials and Methods: From August 2004 to March 2017, 105 ICC patients were eligibly enrolled in the ThirdAffiliated Hospital of Sun Yat-sen University. Preoperative clinical information of enrolledpatients was collected. Expression LC3B in the ICC specimen was detected by immunohistochemistry. Results: The 5-year RFS and OS in this cohort were 15.7% and 29.6%, respectively. On multivariateCox regression analysis, independent risk factors for 5-year OS were cancer antigen 125,microvascular invasion, LC3B expression and lymph node metastasis. Except for the above4 factors, neutrophil/lymphocyte ratio and tumor differentiation were independent factorsfor 5-year RFS. The area under the curve of nomograms for OS and RFS were 0.820 and0.747, respectively. Conclusion The nomograms based on LC3B can be considered as effective models to predict postoperativesurvival for ICC patients.
