Objective: To perform serological identification and molecular analysis of four samples with antibodies against high-frequency antigens, and to track the condition of newborns after delivery. Methods: Blood group serological tests were conducted using tube method, and unexpected antibody screening and identification were performed using polybrene and human globulin card. Gene haplotype analysis of blood group system was performed using PacBio third-generation sequencing. The DNA mutations were confirmed through Sanger sequencing. Results: Four samples showed normal blood types in common blood type systems. However, they were positive in all unexpected antibody screening and identification, with negative direct antiglobulin tests results. Third-generation sequencing revealed 3 cases of c.376C>T homozygous mutation and 1 case of c.421C>A homozygous mutation in the ABCG2 gene. Three pregnant women gave birth to four children, all of whom developed hyperbilirubinemia, accompanied by decreased red blood cell count and normal or low hemoglobin concentration. Conclusion: Four samples were obtained from individuals with the rare Jr(a-) blood group. Immunization during pregnancy led to the production of anti-Jr antibody, which may contribute to hyperbilirubinemia in newborns.

Objective To explore the value of high-frequency ultrasound in the detection of metastatic hepatocellular carcinoma and displaying lesion characteristics. Methods A total of 38 paitients with hepatocellular carcinoma satellite lesions within 40 mm of subcutaneous tissue were underwent low-frequency (1-5 MHz) and high-frequency (6-9 MHz) ultrasound. Detection rates and ultrasonic features were compared. Results High-frequency grayscale ultrasound had a higher detection rate (71.1% vs. 36.8%, P＜0.001). Subgroup analysis showed higher detection rates with chemotherapy history (88.9% vs. 33.3%, P＝0.002), fatty liver (71.9% vs 31.3%, P＜0.001) or superficial lesion (within 20 mm, 76.5% vs 41.2%, P＝0.031). High-frequency ultrasound also showed clearer margins (P＝0.004) and more arterial-phase rim enhancement (P＝0.007). Conclusions 6-9 MHz ultrasound detects metastatic hepatocellular carcinoma, especially superficial lesions, more effectively than 1-5 MHz ultrasound and better visualizes characteristics.

Shengma Gegentang is one of the classic formulas in the Catalogue of Ancient Classic Prescriptions （Second Batch）. This study reviewed ancient and modern literature and used literature tracing and bibliometric methods to analyze the historical evolution， efficacy， indications， dosage decoctions， and modern clinical disease spectrum of Shengma Gegentang. The results indicated that the earliest record of Shengma Gegentang can be found in the Taiping Huimin Heji Jufang of the Song dynasty， but its origin can be traced back to the Shaoyao Siwu Jiejitang in the Beiji Qianjin Yaofang of the Tang dynasty. The composition dosage of Shengma Gegentang is 413 g of Cimicifugae Rhizoma， 619.5 g of Puerariae Lobatae Radix， 413 g of Paeoniae Radix Alba， and 413 g of Glycyrrhizae Radix et Rhizoma， which are ground into coarse powder. Each dose is 12.39 g， and the amount of water added is 300 mL. 100 mL of solution is decocted and taken at the right time. The four drugs in the formula play the role of relieving exterior syndrome， penetrating pathogenic factors， and detoxicating together. Its indications are widely involved in internal medicine， pediatrics， surgery， ophthalmology and otorhinolaryngology， obstetrics and gynecology， sexually transmitted diseases， and other diseases， such as measles， sores， acne， spots， surgical gangrene， red eyes， toothache， chancre， and fetal poison. The epidemic diseases treated by Shengma Gegentang are complicated， including rash， pox， macula， numbness， summer diarrhea， dysentery， sha disease， febrile symptoms， spring warmth， winter warmth， and cold pestilence. At the same time， it is a plague prevention formula. Although Shengma Gegentang has a wide range of indications， it cannot be separated from the pathogenic mechanism of evil Qi blocking the muscle surface and heat in the lungs and stomach. The modern clinical disease spectrum of Shengma Gegentang involves the ophthalmology and otorhinolaryngology system， nervous system， pediatric-related diseases and syndromes， skin system， hepatobiliary system， and digestive system. It plays a key role in the treatment of epidemic diseases such as measles， chronic hepatitis B， dysentery， and tetanus.

Insufficient alveolar bone thickness increases the risk of periodontal dehiscence and fenestration, especially in orthodontic tooth movement. Abaloparatide (ABL), a synthetic analog of human PTHrP (1-34) and a clinical medication for treating osteoporosis, has recently demonstrated its potential in enhancing craniofacial bone formation. Herein, we show that intraoral submucosal injection of ABL, when combined with mechanical force, promotes in situ alveolar bone thickening. The newly formed bone is primarily located outside the original compact bone, implying its origin from the periosteum. RNA sequencing of the alveolar bone tissue revealed that the focal adhesion (FA) pathway potentially mediates this bioprocess. Local injection of ABL alone enhances cell proliferation, collagen synthesis, and phosphorylation of focal adhesion kinase (FAK) in the alveolar periosteum; when ABL is combined with mechanical force, the FAK expression is upregulated, in line with the accomplishment of the ossification. In vitro, ABL enhances proliferation, migration, and FAK phosphorylation in periosteal stem cells. Furthermore, the pro-osteogenic effects of ABL on alveolar bone are entirely blocked when FAK activity is inhibited by a specific inhibitor. In summary, abaloparatide combined with mechanical force promotes alveolar bone formation via FAK-mediated periosteal osteogenesis. Thus, we have introduced a promising therapeutic approach for drug-induced in situ alveolar bone augmentation, which may prevent or repair the detrimental periodontal dehiscence, holding significant potential in dentistry.

Objective To analyze the epidemiological characteristics of newly diagnosed occupational diseases in Guangdong Province from 2019 to 2023. Methods Data on newly diagnosed occupational diseases reported in Guangdong Province from 2019 to 2023 were collected from the national occupational disease network reporting system. The spectrum of occupational diseases and their distribution by region, industry, and population were analyzed. Results A total of 4 136 newly diagnosed occupational disease cases were reported in Guangdong Province from 2019 to 2023, showing an overall downward trend. Newly diagnosed cases were classified into eight categories and 53 types of occupational diseases. In terms of the number of cases, the top five categories were occupational diseases of the ear, nose, throat and oral cavity;occupational pneumoconiosis and other respiratory diseases; occupational diseases caused by physical factors; occupational chemical poisoning; and occupational tumors, accounting for 98.62% of all cases. The top ten specific disease types were occupational noise-induced deafness, occupational silicosis, occupational other pneumoconiosis, occupational chronic benzene poisoning, occupational heatstroke, occupational hand-arm vibration disease, occupational coal workers′ pneumoconiosis, occupational welders′ pneumoconiosis, occupational tumor (leukemia caused by benzene exposure), and occupational chronic n-hexane poisoning, accounting for 94.85% of all cases. Most of the cases were distributed in the Pearl River Delta region, accounting for 89.19%; as well as manufacturing industry, accounting for 84.89%. Male cases accounted for 87.02%. Most diagnoses occurred in individuals aged >40-60 years, accounting for 74.73%. Conclusion Newly diagnosed occupational diseases in Guangdong Province from 2019 to 2023 showed the following characteristics: concentration of categories and disease types, polarization of regional distribution, industry clustering, and population difference. The disease spectrum is evolving from a dual-disease predominance toward a multi-disease predominance.

Objective The aim of this study was to explore the predictive value of the systemic inflammatory immune nutri-tion score(SIINS)for the prognosis of immunotherapy for advanced gastric cancer.Methods A retrospective analysis was conducted on the clinical data of 202 patients with advanced gastric cancer who received treatment with programmed death-1(PD-1)inhibitors at the Harbin Medical University Cancer Hospital from October 2018 to July 2022.The LASSO regression analysis was used to screen prognostic indicators,construct SIINS indicator,determine the optimal cutoff value for predicting prognosis using subject operating characteristic curves,and divide patients into the high SIINS and low SIINS groups.Independent prognostic factors for overall survival(OS)were determined using univariate and multivariate Cox regression analyses.Results Four indicators,including lymphocyte count,lactate dehydrogenase,and neutrophil lymphocytes,were selected to construct the SIINS index.The prognosis of patients in the high SIINS group was significantly lower than that in the low SIINS group(P<0.05).The results of the multifactorial Cox regression a-nalysis showed that the Eastern Cooperative Oncology Group(ECOG)score,Geriatric Nutritional Risk Index(GNRI),SIINS,treatment regimen,and number of treatment lines(P<0.05)could serve as the independent predictive prognosis of immunotherapy for advanced gastric cancer.Conclusion SIINS can predict the prognosis of patients with advanced gastric cancer treated with PD-1 inhibitors.

Objective To evaluate the effectiveness of the PDCA cycle in critical value management.Methods PDCA cycle method was applied to manage critical values in an occupational disease hospital.Critical value data from October 2021 to March 2022 were analyzed to identify root causes,followed by corrective measures development and implementation.Post-inter-vention data,from July 2022 to November 2022,were compared with the pre-management data to evaluate the implementation effect of the PDCA cycle on critical value management.Results The application of the PDCA cycle led to a statistically signifi-cant increase in the execution compliance rate for emergency value execution in medical and technical departments increased to 100.00％,and in the clinical departments to 96.77％(P＜0.05).Conclusion PDCA cycle can improve the qualified rate of the implementation of critical value system,ensure patients safety,significantly reduce medical risks,and advance the level of standardization and precision in critical value management within our hospital.

Objective To analyze the value of combined prediction of peripheral blood CD4+,CD3-CD16+CD56+,CD8+,CD19+for the risk of death in patients with Epstein-Barr virus-associated hemophagocytic syn-drome(EBV-HLH).Methods A total of 84 patients with EBV-HLH who were treated in Beijing Friendship Hospital Affiliated to Capital Medical University and Peking University First Hospital from May 2021 to A-pril 2023 were selected and divided into a death group(17 cases)and a survival group(67 cases)according to their survival outcomes within 6 months.The general information and peripheral blood T lymphocyte subsets of the two groups were compared,multivariate Logistic regression analysis was conducted to investigate the influencing factors of death in EBV-HLH patients,and receiver operating characteristic(ROC)curve was used to evaluate the predictive value of peripheral blood T lymphocyte subsets on death in EBV-HLH patients.Results The platelet count,hemoglobin,CD4+and CD3-CD16+CD56+levels in the death group were lower than those in the survival group,while the levels of CD8+and CD19+were higher than those in the survival group(P＜0.05).Multivariate Logistic regression analysis showed that platelet count,hemoglobin,CD4+,and CD3-CD16+CD56+were all independent protective factors for the death of EBV-HLH patients,while CD8+and CD19+were independent risk factors for the death of EBV-HLH patients(P＜0.05).The ROC curve results showed that the area under the curve of combined prediction of CD4+,CD8+,CD19+,CD3 CD16+CD56+for death in EBV-HLH patients was 0.923,with sensitivity and specificity of 94.12％and 80.60％,respectively,which were significantly higher than those predicted by each individual indicator(P＜0.05).Conclusion The abnormal expression of CD4+,CD3-CD16+CD56+,CD8+,and CD19+in peripheral blood of EBV-HLH patients is associated with their survival outcomes,and the combined prediction of CD4+,CD3-CD16+CD56+,CD8+,and CD19+has high reference value for predicting patients'death.
