The shaoyang meridian is an important pivot between the internal organs and meridians system， with the functions of regulating qi and blood， balancing yin and yang， and coordinating the ascending and descending movement of qi. Dysfunction of the shaoyang pivot can lead to spleen and kidney deficiency， impaired liver and gallbladder qi regulation， and stagnation of qi and blood. It is believed that the onset and progression of Crohn's disease are closely related to shaoyang pivot dysfunction， with the core pathogenesis characterized by shaoyang disharmony， spleen deficiency， dampness retention， and blood stasis. Based on this understanding， the treatment principle centers on harmonizing the shaoyang pivot， supplemented by methods such as warming and nourishing the spleen and stomach， tonifying shaoyang， and soothing the liver and benefiting the gallbladder. Acupuncture is employed to target key acupoints along the shaoyang meridian to restore its regulatory functions， improve spleen and stomach transformation and transportation， facilitate liver and gallbladder qi flow， and promote the circulation of qi and blood. This provides a practical therapeutic approach for acupuncture-based treatment of Crohn's disease.

Objective: To design and establish a new method for flow cytometry-based detection of commonly observed highly expressed antigens on red blood cells, and to further evaluate the differences and distribution characteristics of antigen expression levels between ABO blood type homozygotes and heterozygotes in healthy individuals. Methods: Residual blood samples after donor blood type identification by Shanghai Blood Center in April 2024 were collected. Among them, samples of 19 homozygous and 19 heterozygous individuals of type A and type B were selected. Then the expression level of ABO antigen on red blood cells were detected using the new method established in this study and the traditional aldehyde fixed red blood cell method. Both methods were tested independently three times and the results were compared. Results: The mean values of the three detection results of the new method was (×10 /RBC): AA homozygous 3.3±0.5, AO heterozygous 2.8±0.3, BB homozygous 3.6±0.3, BO heterozygous 3.1±2.8. The mean values of the three detection results of the aldehyde fixation method were AA homozygous 5.9±0.9, AO heterozygous 5.0±1.4, BB homozygous 3.8±0.6, and BO heterozygous 3.3±0.4. The average antigen distribution of each genotype followed a normal distribution. Comparing the average antigen expression levels of homozygotes and heterozygotes, both methods showed that A/B homozygotes had higher antigen levels than heterozygotes, with AA being 1.17 to 1.18 times that of AO and BB being 1.15 to 1.16 times that of BO. Comparing the inter batch differences in the three test results of two methods, the new method showed no significant difference in the three test results for four genotypes (P>0.05). The aldehyde fixation method showed significant differences in the test results for all three genotypes (P<0.01) except for BB homozygotes (P>0.05). The reliability and reproducibility of the new method were better than those of the traditional aldehyde fixation method. Conclusion: The antigen expression level of ABO homozygotes is higher than that of heterozygotes, and the difference in antigen level between type A homozygotes and heterozygotes is slightly higher than that of type B. The new method is superior to traditional aldolization fixation methods.

It is believed that the occurrence and development of squamous cell carcinoma （SCC） is closely associated with inflammatory responses. The theory of fire and heat， advocated by LIU Wansu， provides significant clinical guidance for understanding the pathogenesis and treatment of SCC. Based on this theory， the pathological mechanisms and clinical characteristics of SCC at different stages were analyzed. In the precancerous and early stages， the primary pathogenesis is qi stagnation leading to internal generation of constrained heat； in post-surgery， the condition shifts to qi deficiency with latent yin fire； during the treatment phase， the pathogenesis involves accumulation of pathogenic factors， excess toxins， and severe heat toxicity； in the late stage， the main pathology is yin deficiency with toxic heat， and phlegm-stasis obstruction of the internal organs. Corresponding stage-based treatment strategies are proposed. In the early stage， regulating qi movement to dissipate constrained heat； for post-surgery， tonifying qi and raising yang to dispel latent fire； during treatment stage， clearing heat and detoxifying to eliminate cancerous toxins； and in the late stage， nourishing yin and unblocking the bowels to clear deficiency heat.

ObjectiveTo investigate the microbial contamination status of commercially available ready-to-eat (RTE) foods in Songjiang District of Shanghai, to verify the potential food safety hazards, so as to provide a scientific basis for the local regulation of RTE foods and the prevention of foodborne diseases. MethodsA total of 882 food samples from 9 categories of RTE foods were collected in Shanghai from 2017 to 2022. Salmonella, Listeria monocytogenes, Vibrio parahaemolyticus, Staphyloccus aureus and Bacillus cereus were detected according to the standard operating procedures in the Manual for China National Food Contamination and Harmful Factors Risk Monitoring, and which were determined with reference to relevant standards. ResultsA total of 77 samples were found to carry foodborne pathogens, with a total detection rate of 8.73%. Among the 5 foodborne pathogens, Bacillus cereus had the highest detection rate (8.35%), followed by Vibrio parahaemolyticus (5.05%), and the difference of detection rates among the 5 foodborne pathogens was statistically significant (χ²=112.307, P<0.001). Among the 9 categories of RTE food products, the detection rate of foodborne pathogens in RTE fermented/non-fermented soybean products was the highest (27.50%), followed by cold noodles (17.33%) and raw edible aquatic products (9.50%), and the difference in the detection rates of foodborne pathogens among different RTE food categories was statistically significant (χ²=45.909, P<0.001). The detection rate of foodborne pathogens in the third quarter of the year was 10.99%, significantly higher than that in other quarters (χ²=10.329, P=0.016). The detection rate of foodborne pathogens in samples from supermarkets was highest (15.08%), followed by snack bars (11.58%), with a statistically significant difference (χ²=14.108, P=0.015). ConclusionFoodborne pathogens contamination is found in commercially available RTE foods in Songjiang District of Shanghai, especially in RTE fermented/non-fermented soybean products, RTE cold noodles and raw edible aquatic products from supermarkets, snack bars and farm products markets during summer and autumn. Therefore, it is crucial to strengthen supervision and management to avoid the foodborne diseases.

Objective: To summarize the laboratory findings of a case of hemolytic disease of the fetus and newborn (HDFN) caused by Rh system anti-c antibodies and to review the literature, so as to explore the characteristics of anti-c HDFN. Methods: The ABO blood type, Rh blood type, direct antiglobulin test (DAT) results, and the presence of unexpected antibodies and their titers were determined by serological methods. The cases of anti-c HDFN in our laboratory in China and abroad were statistically analyzed, and the incidence of severe HDFN caused by anti-c, anti-D and anti-E was compared. Results: The blood type of the child was B (Rh CcDee) with a positive DAT. Anti-c antibody was detected in both serum and eluate, with a serum antibody titer of 4. The mother’s blood type was AB (Rh CCDee) with a negative DAT, and anti-c antibody was detected in the serum with a titer of 128. Among 20 cases of anti-c HDFN, 17 were DAT positive, and 9 (45%, 9/20) underwent blood transfusion or exchange transfusion. The incidence of severe HDFN was 47.60% (10/21) for anti-c, 47.60% (10/21) for anti-D and 31.30% (5/16) for anti-E. Conclusion: Maternal pregnancy and/or blood transfusion are the main reasons for the production of Rh alloantibodies such as anti-c. The prevention and management of anti-c should be similar to that of anti-D. Rh antigen-matched (five antigens of Rh blood group) transfusion is necessary for women of childbearing age to avoid antibody production, and Rh typing and antibody screening during prenatal examination is recommended to ensure early detection, intervention and treatment.

Objective　This study aims to investigate and compare the clinical characteristics and prognostic factors among primary liver cancer (PLC) patients who had hepatitis B virus (HBV)-induced cirrhosis associated with liver cancer, alcoholic cirrhosis associated with liver cancer, or both HBV and alcoholic cirrhosis associated with liver cancer. 　　　Methods　Inpatients diagnosed with PLC admitted to the First Affiliated Hospital of Fujian Medical University between January 2010 and September 2020 were enrolled and divided into three groups based on the etiology. The follow-up period ends in October 2024. Survival analyses were performed using Kaplan-Meier curves, univariate analysis, and multivariate Cox regression. Results　During the study period, 45 cases of alcoholic cirrhosis associated liver cancer (ALD group), and 71 cases of hepatitis B combined with alcoholic cirrhosis associated liver cancer (HBV+ALD group) were enrolled. At the same time, 73 patients with hepatitis B cirrhosis associated liver cancer (HBV group) during the same period were randomly selected with a ratio of about 1∶1.5, totaling 189 cases. And 183 (96.8%) of the patients were male and 6 (3.2%) were female. The age was (55.93±10.20) years. 109 deaths (57.7%) were recorded. The median survival times were 12 months for the entire cohort, 55 months for HBV group, 36 months for ALD group and 11 months for HBV+ALD group. And the 10-year death rate was 42.5% in HBV group, compared to 66.7% in ALD group and 67.6% in HBV+ALD group. In this study, 93 patients chose either the surgical resection or the radiofrequency ablation as their treatments. The recurrence rate was 69.9%, the median recurrence time was 8 months and the median overall survival time was 39 months. Univariate Cox regression identified that etiology of HBV and ALD, alpha-fetoprotein (AFP)>1 200 ng/mL, Child-Pugh class B and C, Barcelona Clinic Liver Cancer (BCLC) stages of C and D and curative therapies such as surgery and radiofrequency ablation were significantly correlated with overall survival (all P<0.05). Multivariate Cox regression revealed that patients with both HBV and ALD (HR=1.750，95%CI: 1.107-2.765，P=0.017), AFP>1 200 ng/mL (HR=1.649，95%CI: 1.060-2.564，P=0.027), and BCLC stages of C and D (HR=3.404，95%CI: 2.254-5.142，P<0.001) were independent risk factors of mortality in PLC patients with cirrhosis. Conclusions　Among HBV, ALD and HBV+ALD groups, the HBV+ALD group had the shortest median survival time and the highest overall mortality rate, suggesting that alcohol consumption and HBV infection may accelerate the progression of PLC with cirrhosis and worsen its prognosis. HBV infection combined with alcoholic consumption, AFP>1 200 ng/mL, and BCLC stages of C and D were independent risk factors for mortality in PLC patients with cirrhosis.

Objective:To explore the cognition and intention of patients with lower limb deep vein thrombosis (DVT) to participate in patient-reported outcomes (PROs), so as to provide references for the promotion, application, and practice of PROs in lower limb DVT patients in China.Methods:This study adopted the phenomenological qualitative research method. From February to June 2023, 13 lower limb DVT patients admitted to Peking Union Medical College Hospital were selected for semi-structured in-depth interviews. Colaizzi 7-step analysis method was used for analyzing and summarizing data.Results:Thirteen patients with lower limb DVT highly recognized their own value in participating in PROs, namely health benefits, prevention of DVT complications, and reduction of disease uncertainty. Lower limb DVT patients expected to receive support from healthcare professionals, families, and portable and simplified reporting formats to promote their participation in PROs. From the patient 's own perspective, they perceived that insufficient attention to DVT caused by lack of awareness of the hazards of DVT and limited understanding of PROs made it difficult for them to participate in PROs. Conclusions:Lower limb DVT patients have a high intention to participate in PROs. The application and promotion of PROs in lower limb DVT patients in China require joint support from various sectors of society, among which strengthening effective health education for patients and their families and providing multi-channel reporting forms are the key to promoting of PROs.
