ObjectiveTo investigate the potential mechanisms and pathways through which Gandouling （GDL） exerts its effects in the treatment of liver fibrosis in Wilson disease. MethodsSixty male SD rats were randomly divided into six groups： the normal group， the model group， the GDL low-， medium-， and high-dose groups （0.24， 0.48， 0.96 g·kg^-1）， and the penicillamine group （90 mg·kg^-1）， with 10 rats in each group. A copper-loaded Wilson disease rat model was established by gavage administration of 300 mg·kg^-1 copper sulfate pentahydrate to all groups except the normal group. Hematoxylin-eosin （HE） staining and Masson staining were used to observe the pathomorphological changes in the liver. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of hyaluronic acid （HA）， laminin （LN）， procollagen type-Ⅲ peptide （PC-Ⅲ）， and collagen type-Ⅳ （C-Ⅳ）. Transmission electron microscopy was used to examine the ultrastructure of liver tissues. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect the expression levels of liver tissues and serum exosomal long noncoding RNA H19 （LncRNA H19）， phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， and mammalian target of rapamycin （mTOR）. Western blot analysis was performed to assess the expression levels of PI3K， Akt， mTOR， and their phosphorylated forms， as well as autophagy-related proteins Beclin1 and microtubule-associated protein 1 light chain 3B （LC3-Ⅱ/LC3-Ⅰ） in liver tissues. Beclin1 and LC3-Ⅱ fluorescence signal intensity was observed by immunofluorescence. ResultsCompared with the normal group， the model group exhibited inflammatory cell infiltration in hepatocytes， unclear nuclear boundaries with cell cleavage and necrosis， and collagen fiber deposition around confluent areas. The levels of HA， LN， PC-Ⅲ， and C-Ⅳ were significantly elevated （P<0.01）. Transmission electron microscopy revealed an increased number of autophagic vesicles， with autophagic lysosomes exhibiting a single-layer membrane structure following degradation of most envelopes. Expression levels of Beclin1 and LC3-Ⅱ/LC3-Ⅰ were significantly increased （P<0.01）， and fluorescence signals of Beclin1 and LC3-Ⅱ were markedly enhanced. The protein expression levels of PI3K， Akt， mTOR， p-PI3K， p-Akt， and p-mTOR were reduced （P<0.01）， while LncRNA H19 expression was increased （P<0.01）， and mRNA expression levels of PI3K， Akt， and mTOR were decreased （P<0.01）. After treatment with GDL， the degree of liver fibrosis was significantly improved， with decreased levels of HA， LN， PC-Ⅲ， and C-Ⅳ. The number of autophagic vesicles was significantly reduced， and expression levels of Beclin1 and LC3-Ⅱ/LC3-Ⅰ proteins were lower （P<0.01）. The fluorescence signals of Beclin1 and LC3-Ⅱ weakened dose-dependently. The protein levels of PI3K， Akt， mTOR， p-PI3K， p-Akt， and p-mTOR were elevated （P<0.01）， while the expression level of LncRNA H19 was reduced （P<0.01）. Furthermore， the mRNA expression levels of PI3K， Akt， and mTOR increased （P<0.05， P<0.01）. ConclusionGDL may alleviate liver fibrosis and reduce liver injury by regulating the PI3K/Akt/mTOR autophagy signaling pathway via LncRNA H19.

This paper reported a case of juvenile trabecular ossifying fibroma（JTOF） originating from the uncinate process. The main clinical manifestation was nasal obstruction and epiphora. Contrast-enhanced sinus CT revealed an irregular heterogeneous soft tissue mass centered in the right uncinate process, with involvement of the right anterior ethmoid sinus, maxillary sinus ostium, frontal process of the maxilla, and partial nasolacrimal duct. The solid components of the tumor demonstrated enhancement on contrast imaging. The patient underwent endoscopic resection of the right sinonasal tumor under general anesthesia. Postoperative pathological examination confirmed the diagnosis of JTOF. No tumor recurrence was observed during the 3-month follow-up period.

OBJECTIVES: To explore the value of ferroptose-related genes in the diagnosis and prediction of ulcerative colitis (UC). METHODS: We used UC dataset from the GEO database to screen for differentially expressed genes (DEGs) in UC. The DEGs related to ferroptositis were screened from the FerrDb database and their functions were analyzed. The hub genes were identified by constructing the protein-protein interaction network (PPI), the differences in immune infiltration levels between UC and the control group were evaluated using CIBERSORT, and the diagnostic values of the hub genes for UC were verified by using the training set. In a mouse model of UC, we examined the expression levels of the hub genes in the colon tissues of the mice using real-time fluorescence quantitative PCR (qPCR). RESULTS: We identified a total of 76 DEGs related to ferroptosis. Functional enrichment analysis showed that these genes were significantly enriched in ferroptosis and hypoxia pathways. The PPI network identified 10 hub genes, and 9 of them were highly expressed in UC. Analysis of immune cell infiltration showed that 27 cell types were significantly increased in UC (P<0.05), and the immune checkpoints-related genes had the strongest correlation with the hub gene PPARG (P<0.05). Verification analysis using the training set showed that P4HB, PPARG and STAT3 had the best predictive value for UC (P<0.05). In the UC mouse model, the expression of PPARG was significantly decreased and the expressions of P4HB and STAT3 were significantly increased in the colon tissues of the mice as compared with the normal mice. CONCLUSIONS Ferroptose-related genes have significant value for diagnosis and prediction of UC.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.

In this research， a comprehensive examination of historical materia medica， medical literature， medical books and contemporary literature was conducted to systematically compile and verify the naming， origin， geographical variations， quality， medicinal properties and processing of Tremolitum， and combined with the physical analysis of 15 batches of samples， with a view to providing a basis for the quality evaluation. The evidences unequivocally support Yangqishi as the rectification of name， while alternative aliases include Baishi， Shisheng， Yangjushi and Yangshi. The primary source of Tremolitum has been the silicate hornblende mineral tremolite throughout recorded history， and its accompanied minerals are mainly chlorite， talc schist， anthophyllite asbestos， etc. In ancient times， the main production area of Tremolitum was situated in the "Yaoshan Mountain" region of Jinan， Shandong province. Presently， it is primarily produced in Hubei， Henan， Shanxi， Hebei and Shandong provinces. The ancient quality evaluation of Tremolitum includes "white color"， "wolf teeth"， "cloud head and rain foot"， "heron hair"， etc. While， modern materia medica mostly evaluates its quality in terms of color， luster and texture， including the characteristics of needle bundle， grayish-white， glossy and easy to be twisted and crushed. Tremolitum is slightly warm， non-toxic， and possesses a salty taste. It is associated with the kidney meridian， known for its benefits in nourishing the fire of the gate of life， warming the kidneys and strengthening the Yang. Common processing methods include fire calcination， elutriation， and processing with wine. Additionally， there is an exclusive processing method known as the "ascending Tremolitum method". Through the X-ray diffraction（XRD） analysis， the commercially available Tremolitum is mainly composed of tremolite［Ca₂Mg₅（Si₄O₁₁）₂（OH）₂］， and the accompanied minerals are calcite and quartz， etc. Its color includes white， light gray， light green and so on， and it is weight and soft texture， irregular cross-section， with obvious fibrous texture and mostly glassy luster. Among the commercially available Tremolitum， samples with high content of tremolite are characterized by high quality features， such as "white color"， "heron hair" and "ease of tearing". Also， Tremolitum is the Fe-bearing heterogeneous species of tremolite， and the two are often symbiotic. Therefore， by the herbal textual research and the comparison of the properties and composition of Tremolitum and its similar species， it has been verified that the primary source of Tremolitum is the silicate hornblende minerals tremolite and actinolite.

Radiation-induced injury, a body dysfunction caused by irradiation, is associated with the dose, duration, and speed of radiation and is predominantly derived from radiation therapy for patients with malignant tumors. The current clinical treatment mainly includes amelioration of injury, alleviation of symptoms, and improvements in function restoration of the affected sites because of lack of targeted agents specific to radiation-induced injuries. Research and development of preventive and therapeutic agents against radiation-induced injuries are of great significance to reduce the body damages caused by radiotherapy and improve the quality of life of cancer survivors. This review summarizes the radiation-induced injury and its mechanisms, radioprotectants, and therapeutic agents for radiation, and proposes future development directions, so as to provide a reference for alleviation of radiation-induced injury and improvement in prognosis.

Objective To compare the results of accumulation and continuation methods in indoor radon measurement. Methods The radon concentrations in 30 households in 7 provincial capital cities of China were simultaneously measured using both accumulation and continuation methods. Results The radon concentration measured by accumulation method in 30 households ranged from 21 to 323 Bq/m³, with a median M(P₂₅, P₇₅) of 70.5 (43.8, 111). The radon concentration measured by the continuation method ranged from 16.1 to 258 Bq/m³, with a median M(P₂₅, P₇₅) of 100 (51.3, 141). The average relative percent deviation between the two measurement methods was 41.8%. There were significant differences among the measurement results at 8, 16, and 24 h by the continuation method. Pairwise comparisons showed there were statistical diffferences between 8 h and 16 h, as well as between 8 h and 24h; however, no statistical significance was found (P < 0.05), between 16 h and 24 h. Conclusion The overall continuous measurement results of the 30 households were higher than those of cumulation method. The comparison between accumulation and continuation measurement results did not show a high level of correlation (r=0.49). The continuation method is significantly affected by environmental factors, and the length of the measurement period can affect the measurement results. The selection of indoor radon measurement methods should consider the purpose, sample size, and environmental conditions.

Objective:To observe the clinical effect of Shenfu injection in preventing septic cardiomyopathy (SIC) in septic patients.Methods:From June 2022 to January 2023, patients with sepsis or septic shock who did not develop SIC were randomly divided into treatment group and control group according to the ratio of 1:1. In the treatment group, Shenfu injection (50 mL) was pumped intravenously once every 12 hours for 5 days. In the control group, 50 mL of normal saline was pumped intravenously once every 12 hours, and the course of treatment was 5 days. The primary end point was the incidence of SIC in the first 5 days. The secondary end points were the application time of vasoactive drugs, fluid balance in the previous week, hospitalization time in ICU, total ventilation time and 28-day mortality.Results:112 patients were randomly divided into two groups. Seven patients in the treatment group were excluded twice, and finally 49 patients were included in the analysis, while six patients in the control group were excluded twice and 50 patients included in the analysis. The total incidence of SIC in the treatment group within 5 days was significantly lower than that in the control group (42.9% vs. 64.0%, P = 0.035). Among them, the left ventricular systolic dysfunction in the treatment group was significantly lower than that in the control group (24.5% vs 52.0%, P=0.005), and there was no significant difference in the incidence of left ventricular diastolic dysfunction between the two groups. The incidence of right ventricular dysfunction in the control group was 28.0%, which was significantly higher than 10.2% in the treatment group ( P = 0.025). The duration of using vasoconstrictors in the treatment group was 75(48, 97) hours, which was significantly lower than 97(66, 28) hours in the control group ( P = 0.039). The duration of inotropic drugs use in the treatment group was 32(18, 49) h, which was also significantly shorter than 44(25, 61) h in the control group ( P=0.046). The fluid balance of the control group in the first week was (1 260±850) mL, which was significantly higher than (450±520) mL in the treatment group ( P=0.008). There was no statistical difference in ICU stay, total ventilation time and 28-day mortality between the two groups (all P > 0.05). Conclusion:Early application of Shenfu injection can significantly reduce the incidence of SIC, accompanied by less use of vasoactive drugs and positive fluid balance, which has a good clinical application prospect.

Objective:To analyze the trends in refractive error and ocular biological parameters in elementary school students over 5 years, and to investigate the patterns of change before and after myopia onset.Methods:A cohort study was adopted.A total of 1 986 first-grade students from the Anyang Childhood Eye Study were enrolled in this cohort study and their right eye data were taken for analysis, including 1 126 boys and 860 girls.Every year, cycloplegic autorefraction was performed with 1% cyclopentolate eyedrops to obtain the spherical equivalent (SE).The axial length (AL), anterior chamber depth, lens thickness, mean corneal curvature (Km) and other parameters were obtained by ocular biometry.The lens refractive power (LP) was calculated using the Bennett formula.The subjects were assigned to persistent myopia group, non-myopia group and new onset myopia group.According to the age of myopia onset, the new onset myopia group was subdivided into the 8-, 9-, 10-, 11- and 12-year-old myopia groups to compare the differences in refractive error and ocular bioparameters among groups at different time points of follow-up.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Beijing Tongren Hospital, Capital Medical University (No.TRECKY2018-030).Written informed consent form was obtained from the guardians of each subject.Results:All children had a gradual SE drift toward myopia and a gradual increase in the AL with age, and there were significant differences in SE and AL between adjacent follow-up ages within the three groups (all at P<0.05).The earlier the onset of myopia, the higher the myopia SE and the longer the AL of the eye at the same follow-up age, the differences in SE between adjacent groups were statistically significant (all at P<0.05), and the differences in AL between adjacent groups at the follow-up age of 8 to 12 years were statistically significant (all at P<0.05).In the nonmyopia group, SE drifted toward emmetropia at a slow and steady rate of (-0.23±0.27)D/year, and AL also increased slowly and steadily at (0.18±0.13)mm/year.In the new onset myopia group, the changes in SE in the third, second, and first years before myopia onset were (-0.32±0.25), (-0.45±0.33), and (-0.98±0.44)D, and the increases in AL were (0.25±0.12), (0.32±0.15), and (0.48±0.19)mm, respectively.Both SE and AL change rates began to accelerate before myopia onset and slowed down after myopia onset, with statistically significant differences in the overall comparison of SE and AL change rates at different time intervals before and after myopia onset (all at P<0.001).The AL at myopia onset in boys was (24.11±0.70)mm, which was longer than (23.60±0.66)mm in girls ( t=159.71, P<0.01).LP decreased with age in all groups, with a faster rate before the age of 9 years and a slower rate after the age of 9 years.The mean decrease rate in LP was (-0.48±0.19), (-0.44±0.20), (-0.49±0.16), (-0.51±0.18), and (-0.48±0.19)D/year in the persistent myopia group and 8~11-year-old myopia group, respectively, which were significantly faster than -0.42±0.17 D/year in 12-year-old myopia group and (0.37±0.15)D/year in nonmyopia group (all at P<0.05).There was no statistically significant difference in Km among groups at different follow-up ages (all at P>0.05). Conclusions:The AL begins to grow at an accelerated rate 3 years before myopia onset, and the increase rate of the AL slows down after the onset of myopia, but it is still significantly faster than that of non-myopic children.In this process, the decrease in LP plays a compensatory role; there is no significant change in corneal curvature.The AL of males at the onset of myopia is longer than that of females at the same age.AL is an important indicator for the prevention and control of myopia.It is important to consider gender differences and to pay more attention to the growth rate when assessing AL.

Objective:To explore effects and mechanisms of medium and low doses X-ray irradiation on polarization type changes of tumor associated macrophages(TAMs).Methods:Mouse RAW264.7 macrophage line was cultured with supernatant of 4T1 tumor cell culture(4T1-TCS)of mouse breast cancer,and induced to M2 TAMs.On this basis,medium and low doses X-ray irra-diation was conducted,and NO was detected by Griess method,CD86 and CD206 were detected by flow cytometry.ELISA was use to detect cytokines IL-10 and IL-12p70,immunofluorescence was use to detect iNOS and Arg-1.Western blot was used to detect polariza-tion related pathway proteins,and whether medium and low doses of radiation could alter polarization type of TAMs was observed.Results:4T1-TCS induced TAM had decreasing NO secretion and increasing CD206 and Arg-1 expressions,iNOS expression was decreased;with low doses irradiation(0.075 Gy,0.5 Gy,1 Gy)of TCS-TAM,compared with non irradiation group,NO secretion,expressions of CD86,CD206,Arg-1 and iNOS showed no significant changes;medium doses(2 Gy,4 Gy,6 Gy)of irradiation on TCS-TAM resulted in increased secretion of NO,and flow cytometry results showed increased expressions of CD86,decreased CD206 expression;immunofluorescence results showed an increase in iNOS expression and a decrease in Arg-1 expression in cells;ELISA results showed an increase in secretion of IL-12p70 by cells and a decrease in secretion of IL-10.Western blot results showed that NOX2,ATMS1981*,IRF5 proteins expressions were increased.Conclusion:4T1-TCS can successfully induce macrophage RAW264.7 polarize into M2 phenotype,while low dose irradiation has no significant effect on polarization phenotype of TCS-TAM.Medium dose irradiation can induce TCS-TAM polarization into M1 phenotype that inhibits tumor growth,and reversal mechanism of polarization may be related to IRF5 pathway.
