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.

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.

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.

The circadian clock is a highly conserved timekeeping system in organisms, which maintains physiological homeostasis by precisely regulating periodic fluctuations in gene expression. Substantial clinical and experimental evidence has established a close association between circadian rhythm disruption and the development of various malignancies. Research has revealed characteristic alterations in the circadian gene expression profiles in tumor tissues, primarily manifested as a dysfunction of core clock components (particularly circadian locomotor output cycles kaput (CLOCK) and brain and muscle ARNT-like 1 (BMAL1)) and the widespread dysregulation of their downstream target genes. Notably, CLOCK demonstrates non-canonical oncogenic functions, including epigenetic regulation via histone acetyltransferase activity and the circadian-independent modulation of cancer pathways. This review systematically elaborates on the oncogenic mechanisms mediated by CLOCK/BMAL1, encompassing multidimensional effects such as cell cycle control, DNA damage response, metabolic reprogramming, and tumor microenvironment (TME) remodeling. Regarding the therapeutic strategies, we focus on cutting-edge approaches such as chrononutritional interventions, chronopharmacological modulation, and treatment regimen optimization, along with a discussion of future perspectives. The research breakthroughs highlighted in this work not only deepen our understanding of the crucial role of circadian regulation in cancer biology but also provide novel insights for the development of chronotherapeutic oncology, particularly through targeting the non-canonical functions of circadian proteins to develop innovative anti-cancer strategies.

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 To investigate the value of intravoxel incoherent motion diffusion weighted imaging(IVIM-DWI)in quantitatively evaluating the involved muscle in idiopathic inflammatory myopathies(IIM).Methods Totally,50 patients with clinically diagnosed IIM(IIM group)and 15 healthy controls(control group)were selected for bilateral thigh MRI examination,including IVIM-DWI sequences.The right quadriceps(vastus lateralis,vastus intermedius,vastus medialis,and rectus femoris)of all subjects were selected as region of interest(ROI).Single-exponential and double-exponential analysis were employed to quantitatively measure IVIM-DWI parameters,including apparent diffusion coefficient(ADC),D,f,and D*.Based on T1WI and T2WI fat-suppressed images of the right quadriceps,these muscles were divided into affected and unaffected groups.One-way analysis of variance was used to compare IVIM-DWI parameters between affected group,unaffected group,and control group.Receiver operating characteristic(ROC)curve was performed to analyze the differences in IVIM-DWI parameters among the above groups.Results The D and ADC values were significantly higher in the affected group compared to the unaffected group and the control group(P＜0.001).ROC curve analysis revealed that D and ADC values had moderate diagnostic significance with area under the curve(AUC)of 0.794 and 0.882,respec-tively.The cutoff values for D values and ADC values were 1.63×10-3 mm2/s and 1.44×10-3 mm2/s,respectively.Additionally,MRI follow-up performed one year after treatment in three patients with IIM showed significant resolution of inflammatory edema in thigh muscles,accompanied by a marked decrease in IVIM-DWI parameter values,particularly D values and ADC values.Conclusion The affected muscle in IIM show distinctive diffusion characteristics,and IVIM-DWI parameters,especially D values and ADC val-ues,show a higher diagnostic value for assessing muscle status in IIM.In addition,IVIM-DWI parameters also demonstrate a promis-ing value in the follow-up of IIM,which requires further confirmation in larger cohorts.

Objective:To analyze the effect of analysis plan, do, check, and action (PDCA) cycle in improving the completion rate of sepsis bundle treatment in sepsis patients and the knowledge-attitude-practice of sepsis bundle treatment in medical staff.Methods:Using the historical control method, sepsis patients admitted to the Emergency Trauma Intensive Care Unit of Shandong Provincial Hospital Affiliated to Shandong First Medical University were selected as the research objects by convenience sampling. The 35 patients admitted from January to December 2021 will be included in the control group; from June 2022 to June 2023, 28 patients were admitted to the observation group. The control group received routine nursing care, while the observation group received intervention based on the PDCA cycle. The completion rate of sepsis bundle treatment before and after PDCA cycle implementation was compared. The 27 nurses and 5 doctors working in trauma care unit were investigated by using a self-designed questionnaire on their knowledge and practice level of sepsis bundle treatment. The completion rate of sepsis bundle treatment before and after the implementation of PDCA cycle was compared.Results:The control group included 19 males and 16 females, aged (61.77 ± 8.64) years. The observation group included 13 males and 15 females, aged (60.61 ± 10.20) years. After the implementation of PDCA cycle, the completion rate of 3h bundle treatment for sepsis in the observation group was 89.29% (25/28), which was higher than 31.42% (10/35) in the control group, with a statistically significant difference ( χ2=23.22, P<0.05). The completion rate of sepsis bundle treatment within 6 hours in the observation group was 11/11, which was higher than 5/9 in the control group, with a statistically significant difference ( χ2=6.11, P<0.05). Moreover, after the implementation of PDCA cycle, the total score and sub-scale scores of the knowledge-attitude-practice among medical staffs increased from 86.60 ± 10.33, 21.00 ± 4.74, 18.00 ± 1.58, and 47.60 ± 4.10 to 100.00 ± 5.20, 27.60 ± 2.51, 19.60 ± 0.55, and 52.80 ± 2.28 respectively, with statistically significant differences ( t values were -5.10 - -3.14, all P<0.05). Conclusions:PDCA cycle can improve the completion rate of sepsis bundle treatment and improve the level of knowledge, attitude and practice of medical staff.
