Malignant tumors are one of the major diseases that endanger human life and health. Chinese medicine has unique advantages in clinical anti-tumor treatment. However, how to translate the anti-tumor effects of Chinese medicine into clinical practice is the core issue that must be addressed in the process of treating malignant tumors with traditional Chinese medicine (TCM). Unlike modern chemical drugs, the compatibility application of Chinese medicine is the key factor that determines whether Chinese medicine can achieve optimal anti-tumor efficacy and realize the goal of "enhancing efficacy and reducing toxicity". The formulation structure based on this compatibility is the basic form for the safe, efficient, and rational clinical use of anti-tumor Chinese medicine, and it mainly includes three categories: herb pairs, tri-herbal combinations, and compound compatibility. Although herb pairs have the characteristics of a simple structure and strong targeting (enhancing efficacy and reducing toxicity), they often have a single effect and cannot fully address the complex pathogenesis of tumors. As a result, herb pairs are rarely used alone in practice. Compared to herb pairs, tri-herbal combinations broaden the application scope of herbs in clinical treatment, but their therapeutic range remains limited. The traditional "sovereign, minister, assistant, and guide" compound prescription, which includes herb pairs and tri-herbal combinations, improves the efficacy of herbs in treating serious diseases, hypochondriasis, chronic diseases, and miscellaneous disorders. However, due to the limitations of its historical background, it has not been integrated with modern clinical practice and modern pharmacological research, which restricts the development of compound compatibility theory. With the emergence of modern medical technology, it has been combined with traditional compatibility theory of Chinese medicine to create an innovative modern compatibility theory. This includes the "aid medicine" theory derived from modern Chinese medicine pharmacology, which compensates for the inability of the "sovereign, minister, assistant, and guide" theory to accurately apply medicine. Additionally, the "state-targeted treatment based on syndrome differentiation" theory, developed from pharmacology and modern medicine, addresses the deficiency in disease cognition in the "sovereign, minister, assistant, and guide" theory. Under the guidance of these compatibility forms and theories, clinical anti-tumor Chinese medicine can exert its maximum anti-tumor efficacy, which is of great significance for the application of Chinese medicine in clinical tumor treatment.

[Objective] To analyze the distribution of Rh blood group phenotype in some ethnic groups in China, so as to provide references for accurate blood transfusion. [Methods] The data of CNKI, Wanfang data and VIP were retrieved using "Rh blood group" and "nationality", and the search of PubMed database was conducted with the keywords "Rh blood group", "nationalities", "ethnic groups" and "China", with retrieval time until September 19, 2024 Data were extracted from eligible studies and the literature quality was evaluated using the criteria for cross-sectional studies in STROBE statement. Meta analysis was performed using Stata 11.0 software. [Results] A total of 350 relevant literature were retrieved, of which 26 were included. The total sample size for Rh phenotype distribution detection were 31 432, and the total population for RhD negative screening was 47 227, covering 26 ethnic groups. Meta-analysis revealed that the Rh blood groups phenotype distribution in certain ethnic populations in China was mainly CCDee 46.7% (95%CI=46.2%-47.2%), CcDEe 30.1% (95%CI=29.5%-30.6%), and CcDee 9.0% (95%CI=8.7%-9.3%). Analysis of the RhD-negative phenotype indicated an negative rate of RhD of 0.3% (95%CI=0.2%-0.3%), with the main phenotype distributions of ccdee at 0.2% (95%CI=0.1%-0.2%) and ccdEe at 0.2% (95%CI=0.0%-0.4%). The meta-analysis results of the distribution of common phenotypes among different ethnic groups showed that the CCDee phenotype was mainly distributed as Hani>Dong>Buyi>Miao>Tujia>Hui>Zang>Kazakh>Mongol>Uygur; the CcDEe phenotype: Zang>Mongol>Hui; the CcDee phenotype: Uygur>Kazakh>Mongol>Zang>Hui>Dong>Miao>Tujia>Buyi; the ccDEE phenotype: Zang>Hui=Mongol. The results of this study are similar to those of Qingdao population in China, but differ from studies conducted in North India, German individuals of European ancestry and Saudi Arabian populations. [Conclusion] The distribution of Rh blood group phenotypes in some ethnic groups in China shows no significant difference compared to the Han population, but there are differences when compared to populations in other countries and regions.

ObjectiveTo investigate the effect of transplantation of bone marrow mesenchymal stem cells (BMSCs) co-cultured with bone marrow-derived M2 macrophages (M2-BMDMs), named as BMSCM2, on a rat model of liver cirrhosis induced by carbon tetrachloride (CCl4)/2-acetaminofluorene (2-AAF). MethodsRat BMDMs were isolated and polarized into M2 phenotype, and rat BMSCs were isolated and co-cultured with M2-BMDMs at the third generation to obtain BMSCM2. The rats were given subcutaneous injection of CCl4 for 6 weeks to establish a model of liver cirrhosis, and then they were randomly divided into model group (M group), BMSC group, and BMSCM2 group, with 6 rats in each group. A normal group (N group) with 6 rats was also established. Since week 7, the model rats were given 2-AAF by gavage in addition to the subcutaneous injection of CCl4. Samples were collected at the end of week 10 to observe liver function, liver histopathology, and hydroxyproline (Hyp) content in liver tissue, as well as changes in the markers for hepatic stellate cells, hepatic progenitor cells, cholangiocytes, and hepatocytes. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the N group, the M group had significant increases in the activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (P<0.01); compared with the M group, the BMSC and BMSCM2 groups had significant reductions in ALT and AST (P<0.01), and the BMSCM2 group had significantly better activities than the BMSC group (P<0.05). Compared with the N group, the M group had significant increases in Hyp content and the mRNA and protein expression levels of alpha-smooth muscle actin (α-SMA) in the liver (P<0.01); compared with the M group, the BMSC and BMSCM2 groups had significant reductions in Hyp content and the expression of α-SMA (P<0.05), and the BMSCM2 group had a significantly lower level of α-SMA than the BMSC group (P<0.01). Compared with the N group, the M group had significant increases in the mRNA expression levels of the hepatic progenitor cell markers EpCam and Sox9 and the cholangiocyte markers CK7 and CK19 (P<0.01) and significant reductions in the expression levels of the hepatocyte markers HNF-4α and Alb (P<0.01); compared with the M group, the BMSC and BMSCM2 groups had significant reductions in the mRNA expression levels of EpCam, Sox9, CK7, and CK19 (P<0.05) and significant increases in the mRNA expression levels of HNF-4α and Alb (P<0.05), and compared with the BMSC group, the BMSCM2 group had significant reductions in the mRNA expression levels of EpCam and CK19 (P<0.05) and significant increase in the expression level of HNF-4α (P<0.05). ConclusionM2-BMDMs can enhance the therapeutic effect of BMSCs on CCl4/2-AAF-induced liver cirrhosis in rats, which provides new ideas for further improving the therapeutic effect of BMSCs on liver cirrhosis.

ObjectiveTo investigate the efficacy and safety of sofosbuvir/velpatasvir alone or in combination with ribavirin in Chinese patients with genotype 3B HCV/HIV infection. MethodsA total of 299 patients with genotype 3B HCV/HIV infection who attended The Third People’s Hospital of Kunming from January 2017 to December 2020 were enrolled and treated with sofosbuvir/velpatasvir alone or in combination with ribavirin for 12 weeks, and they were followed up for 12 weeks after drug withdrawal. The patients were evaluated in terms of sustained virologic response at 12 weeks after treatment (SVR12) and adverse reactions. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; the Agresti-Coull method was used to evaluate the 95% confidence interval (CI) of SVR12; univariate and multivariate non-conditional logistic regression analyses were used to investigate the influencing factors for SVR. ResultsThe 299 patients with genotype 3B HCV/HIV infection had a mean age of 43.92±6.84 years, among whom the male patients accounted for 77.3% (231/299), the patients with liver cirrhosis accounted for 36.5% (109/299), the patients with a history of antiviral therapy accounted for 13.4% (40/299), and the patients receiving sofosbuvir/velpatasvir combined with ribavirin accounted for 27.8% (83/299). The overall SVR was 87.0% (260/299) for all patients, and there was no significant difference in SVR12 between the patients receiving sofosbuvir/velpatasvir alone and those receiving sofosbuvir/velpatasvir combined with ribavirin (87.5% vs 85.5%, χ2=0.203, P=0.653). There was a significant difference in SVR12 between the patients without liver cirrhosis and those with liver cirrhosis (90.0% vs 81.7%, χ2=4.256, P=0.039), and the patients receiving antiviral therapy for the first time had a significantly higher SVR12 than the treatment-experienced patients (93.4% vs 45.0%, χ2=71.670, P<0.001). The univariate and multivariate logistic regression analyses showed that platelet count (odds ratio [OR]=0.957, 95%CI: 0.931 — 0.984, P=0.002), liver stiffness measurement (OR=1.446, 95%CI: 1.147 — 1.822, P=0.002), and experience in treatment (OR=13.807, 95%CI: 2.970 — 64.174, P=0.001) were independent influencing factors for SVR in patients with genotype 3B HCV/HIV infection. There were 41 cases of serious adverse events, all of which occurred within 2 weeks after antiviral therapy, and 28 cases were resolved without drug withdrawal or active treatment, while 13 cases were not resolved after active treatment and were resolved after the antiviral drugs were stopped for 2 — 5 days, with no similar reactions observed when the drugs were used again after remission. ConclusionSofosbuvir/velpatasvir alone or in combination with ribavirin has relatively good efficacy and safety in patients with genotype 3B HCV/HIV infection.

Objective:To explore the correlation between clinical classification and genotype and prognosis among Chinese children with Very-long chain acyl-CoA dehydrogenase deficiency (VLCADD).Methods:A Chinese pedigree affected with VLCADD admitted at the First People′s Hospital of Yunnan Province in February 2019 was selected as the study subject. The characteristics of disease onset, diagnosis and treatment and prognosis were retrospectively analyzed. Relevant literature was also systematically searched and reviewed.Results:The proband, a 1-year-old boy, had the clinical manifestations of frequently vomiting, hypoglycemia, abnormal liver function and myocardial enzymes. Tandem mass spectrometry screening showed significantly elevated C14, C14: 1, C16: 1, C16: 2, C18 and C14/C8. Genetic testing revealed that he has harbored compound heterozygous variants of the ACADVL gene, namely c. 664G>A (p.G222R) and c. 1345G>A (p.E449K), which were respectively derived from his father and mother. The child was diagnosed with VLCADD cardiomyopathy type and deceased 2 weeks later. Literature review has identified 60 Chinese children with VLCADD. The clinical classifications were mainly cardiomyopathy type and liver disease type, which accounted for 73.3% (43/60). The combination of ACADVL gene variants were correlated with the clinical classifications of VLCAD. Children with one or two loss-of-function (LOF) mutations showed more severe clinical manifestation and a higher mortality. Cardiomyopathy type had the poorest prognosis, with a mortality rate of 76.9% (20/26). C14: 1 may be used as an indicator for the diagnosis of VLCADD, but cannot be used for clinical subtyping and prognosis evaluation. The c. 1349G>A (p.R450H) variant had the highest frequency among the Chinese patients, accounting for 10.8% (13/120). Conclusion:The clinical classifications of VLCADD are strongly correlated with the prognosis, and LOF mutations are more common in those with severe clinical manifestations. c. 1349G>A (p.R450H) may be the most common variant among the Chinese patients, and early screening and diagnosis can greatly improve the prognosis of patients.

Objective :
The unintentional retention of needles in patients can lead to severe consequences. To enhance acupuncture safety, the study aimed to develop a deep learning-based cloud system for automated process of counting acupuncture needles.
Methods:
This project adopted transfer learning from a pre-trained Oriented Region-based Convolutional Neural Network (Oriented R-CNN) model to develop a detection algorithm that can automatically count the number of acupuncture needles in a camera picture. A training set with 590 pictures and a validation set with 1 025 pictures were accumulated for finetuning. Then, we deployed the MMRotate toolbox in a Google Colab environment with a NVIDIA Tesla T4 Graphics processing unit (GPU) to carry out the training task. Furthermore, we integrated the model with a newly-developed Telegram bot interface to determine the accuracy, precision, and recall of the needling counting system. The end-to-end inference timewas also recorded to determine the speed of our cloud service system.
Result:
In a 20-needle scenario, our Oriented R-CNN detection model has achieved an accuracy of 96.49%, precision of 99.98%, and recall of 99.84%, with an average end-to-end inference time of 1.535 s.
Conclusion
The speed, accuracy, and reliability advancements of this cloud service system innovation have demonstrated its potential of using object detection technique to improve acupuncture practice based on deep learning.

ObjectiveTo investigate the infestation and disposal of bedbugs in Shanghai, and provide scientific evidence for comprehensive prevention and control of bedbugs. MethodsA questionnaire survey was conducted in the pest control operations (PCOs) of Shanghai Association for Health Promotion to investigate the infestation and disposal of bedbugs. The questionnaire included basic information of the unit, bedbug disposal experience, type of environment of bedbug infestation, main disposal site, main treatment method, main drug and formulation, and evaluation of the disposal. Chi-square test was used for comparison between groups. ResultsOf the 116 PCOs, 78 (67.24%) had conducted bedbug disposal, and 29.49% had conducted the disposal no less than 5 times in the past three years. The main types of environment of bedbug infestation were dormitories (46.96%), hotels (18.78%), and households (20.44%). Additionally, bedbug infestation was found in nursing homes, prisons and detention centers, and transport vehicles. Bed frame/bed board/mattress (32.42%) was the main site of bedbug infestation, followed by mat (19.63%). Chemical spraying was the most common method for bedbug disposal (98.72%), followed by high-temperature steam (11.54%). The main drug used in chemical spraying were pyrethroids (69.23%), nicotinoids (60.26%) and organophosphorus (42.31%), for which the main formulation were suspended insecticides (55.13%), followed by wettable powders (43.59%) and emulsifiers (43.59%). Furthermore, 89.74% of the PCOs performed the assessment after disposal, in which the control effect was generally satisfactory. ConclusionBedbug infestation is relatively common in Shanghai. Dormitories, hotels and households are places where bedbug infestation is more likely to occur. Bed frame, bed board and mattress are the most vulnerable sites to bedbug infestation. Combination of physical and chemical methods should be used for disposal of bedbug infestation.

Objective:To determine the clinical application value of transcranial sonography (TCS) in the diagnosis of attention deficit hyperactivity disorder (ADHD) in children.Methods:A total of 50 children aged 6-12 years diagnosed with ADHD (ADHD group) and 45 age-matched healthy children (control group) who presented to Suzhou Municipal Hospital and Children′s Hospital of Soochow University from August 2021 to August 2022 were prospectively enrolled for TCS examination. ADHD was diagnosed in accordance with the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-Ⅴ) criteria established by the American Psychiatric Association.Based on clinical symptom characteristics, ADHD was further classified into 3 subtypes, including 14 cases of predominantly inattentive, 3 cases of predominantly hyperactive/impulsive, and 33 cases of combined presentation. The substantia nigra(SN) hyperechoic area and the ratio of SN hyperechoic area to midbrain area (S/M) were measured and compared between the two groups. The examination of the correlation was performed between SN hyperechoic area, S/M ratio, and DSM-Ⅴ scores within the ADHD group.Results:Semi-quantitative analysis: the proportion of the SN grade Ⅲ or more in ADHD group was significantly higher than that in control group [96.00%(48/50) vs 13.3%(6/45), P<0.05]. Quantitative analysis: the area of SN hyperechogenicity and the ratio of S/M were significantly larger in ADHD group than in control group [0.32(0.22, 0.38)cm 2 vs 0.00(0.00, 0.00)cm 2, 7.08(5.11, 8.75)% vs 0.00(0.00, 0.00)%, all P<0.05]. Correlation analysis: The SN hyperechoic area and S/M ratio showed no significant correlations with DSM-Ⅴ scores in the ADHD group ( r=0.144, 0.142, all P>0.05). Conclusions:TCS can detect the SN echo enhancement of ADHD children, and the proportion of SN echo enhancement, SN hyperechoic area and S/M ratio are significantly higher than those of normal children, but the SN hyperecho area and S/M ratio are not significantly correlated with DSM-Ⅴ scores.
