This paper summarizes Professor WANG Xiuxia's clinical experience in treating hyperprolactinemia using the liver soothing therapy. Professor WANG identifies liver qi stagnation and rebellious chong qi （冲气） as the core pathomechanisms of hyperprolactinemia. Furthermore， liver qi stagnation may transform into fire or lead to pathological changes such as spleen deficiency with phlegm obstruction or kidney deficiency with essence depletion. The treatment strategy centers on soothing the liver， with a modified version of Qinggan Jieyu Decoction （清肝解郁汤） as the base formula. Depending on different syndrome patterns such as liver stagnation transforming into fire， liver stagnation with spleen deficiency， or liver stagnation with kidney deficiency， heat clearing， spleen strengthening， or kidney tonifying herbs are added accordingly. In addition， three paired herb combinations are commonly used for symptom specific treatment， Danggui （Angelica sinensis） with Chuanxiong （Ligusticum chuanxiong）， Zelan （Lycopus lucidus） with Yimucao （Leonurus japonicus） ， and Jiegeng （Platycodon grandiflorus） with Zisu （Perilla frutescens）.

Objective: To study the effect of nano hemoglobin-based oxygen carrier (nano-HBOC) on radiosensitivity of lung cancer H385 cells. Methods: Using 95% N and 5% CO , a lung cancer cell line was constructed in a hypoxic environment, and H385 cells were treated with different concentrations of nano-HBOC and irradiated (4Gy) by an irradiator, and the IC50 concentration was calculated. The cells were detected by flow cytometry (reactive oxygen species, ROS) ROS test. Using GEO database, KEGG pathway enrichment analysis was carried out to predict possible pathways. The levels of lipid peroxidation and Fe were observed by fluorescence microscope, and the proteins related to iron death pathway were detected by Western-blot. Results: Compared with the control cells, the activity and density of the cells were significantly decreased by nano-HBOC combined with radiotherapy, with a notable proportion of cells exhibiting deteriorated status. There is a positive correlation between ROS level and nano-HBOC concentration, especially after radiotherapy. Radiotherapy combined with nano-HBOC significantly increased the levels of lipid peroxidation and Fe in H385 cells, while decreasing the levels of iron death pathway proteins slc7a11 and GPX4, and increasing the level of ACSL4. Conclusion: Nano-HBOC enhances the radiosensitivity of lung cancer H385 cells.

[Objective] To extract hemoglobin (Hb) from red blood cells using osmotic pressure swelling method, expected to achieve a hemoglobin dissolution rate of ≥80% and a cell membrane integrity rate of ≥70%. [Methods] Human umbilical cord blood red blood cells were used as raw materials and phosphate buffer solution was used as the swelling solution for red blood cells. A three factor three-level orthogonal experiment (n=3) was conducted to determine the optimal matching conditions for selecting the osmolality molar concentration of phosphate buffer solution, pH value of hypotonic phosphate buffer solution and volume ratio of hypotonic phosphate buffer solution to washed red blood cells. Red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions. The hemoglobin dissolution rate and cell membrane integrity rate were checked. In the expanded comparative experiment, red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions, which was filtered by ultrafiltration membranes. The filtration time and hemoglobin yield were checked. [Results] The optimal matching conditions for preparing red blood cell swelling solution were obtained through orthogonal experiment as follows: osmotic pressure molar concentration was 30 mOsmol/Kg, pH was 7.8, and phosphate buffer to red blood cell volume ratio was 6∶1. On the basis of the above conditions, the red blood cell swelling solution sample was compared with the original process sample: the hemoglobin dissolution rate was (82.4±1.8)% vs (78.6±3.0)% (P<0.05), and the cell membrane integrity rate was (65.8±4.0)% vs (28.7±2.3)% (P<0.05). In the expanded comparative experiment, the optimal matching conditions were compared with the original process conditions: filtration time(s) (327±9) vs (434±13) (P<0.05), and hemoglobin yield was (72.3±1.2)% vs (66.0±1.4)% (P<0.05). [Conclusion] Compared with the original preparation process, the hemoglobin extraction process which optimized through orthogonal experiments greatly reduces the cell membrane fragmentation rate and minimizes the entry of cell membrane matrix into the target solution, ensuring a slightly higher hemoglobin dissolution rate, and reducing the preparation difficulty for the subsequent cell membrane separation and further purification.

Objective:To analyze the short-term clinical efficacy and safety of arsenic trioxide (ATO) combined with a modified N7 induction regimen in the treatment of children with high-risk neuroblastoma (NB).Methods:This study was a prospective, single-arm, multicenter phase Ⅱ clinical study. Sixty-seven high-risk NB children from eight units of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, Wuhan Children′s Hospital of Tongji Medical College of Huazhong University of Science and Technology, First Affiliated Hospital of Guangxi Medical University, Hainan General Hospital, Affiliated Hospital of Guangdong Medical University, Kunming Children′s Hospital, Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology, and Guangdong Provincial Agricultural Reclamation Center Hospital were enrolled from January 2019 to August 2023 and were treated with ATO combined with a modified N7 induction regimen. The efficacy and adverse effects at the end of induction chemotherapy were assessed and analyzed, and the differences in the clinical characteristics were further compared between the treatment-responsive and treatment-unresponsive groups by using the Fisher′s exact test.Results:Among 67 high-risk NB children, there were 40 males (60%) and 27 females (40%), with the age of disease onset of 3.5 (2.6, 4.8) years. Primary NB sites were mostly in retroperitoneum (including adrenal gland) (56/67, 84%) and the common metastases sites at initial diagnosis were distant lymph node in 25 cases (37%),bone in 48 cases (72%),bone marrow in 56 cases (84%) and intracalvarium in 3 cases (4%). MYCN gene amplification were detected in 28 cases (42%). At the end of induction, 33 cases (49%) achieved complete remission, 29 cases (43%) achieved partial remission, 1 case (1%) with stable disease, and 4 cases (6%) were assessed as progressive disease (PD). The objective remission rate was 93% (62/67) and the disease control rate was 94% (63/67). The percentage of central system metastases at the initial diagnosis was higher in the treatment-unresponsive group than in the treatment-responsive group (2/5 vs. 2% (1/62), P=0.013), whereas the difference in MYCN gene amplification was not statistically significant between two groups (3/5 vs.40% (25/62), P=0.786). Grade Ⅲ or higher adverse reactions during the induction chemotherapy period were myelosuppression occurred in 60 cases (90%), gastrointestinal symptoms occurred in 33 cases (49%), infections occurred in 20 cases (30%), hepatotoxicity occurred in 4 cases (6%), and cardiovascular toxicity occurred in 1 case (2%). There were no chemotherapy-related deaths. Conclusion:ATO combined with N7-modified induction regimen had a superiority in efficacy and safety, which deserved further promotion in clinical practice.

Acute disseminated encephalomyelitis（ADEM）is a common inflammatory demyelinating disease of the central nervous system in children.The etiology is not yet clear，but it is currently mainly believed to be related to the activation of autoimmune reactions following infection.ADEM is typically a monophasic disease，unlike other demyelinating diseases such as multiple sclerosis and neuromyelitis optica spectrum disorders.With the increasing recognition，understanding，and detection of myelin oligodendrocyte glycoprotein antibodies in recent years，the diagnosis and treatment of ADEM may further evolve.The diagnosis of ADEM is clinical and requires exclusion of other infectious，inflammatory，neoplastic，and genetic conditions.The acute phase treatment methods include intravenous injection of high-dose corticosteroids，therapeutic plasma exchange，and intravenous immunoglobulin，with a generally good prognosis.This review summarizes the current knowledge on the pathogenesis，epidemiology，clinical features，diagnosis and differentiation，treatment，and prognosis of ADEM in children.

Objective To systematically analyze and identify key risk factors for postoperative pulmonary hemorrhage u-sing a combination of the random forest(RF)model and traditional logistic regression analysis,so as to provide data support for clinical practice.Methods This study included patients who underwent needle biopsy of lung masses from January 2020 to December 2023 in the Department of Interventional Therapy,Cancer Hospital,Tianjin Medical University.There were 844 cases,including 387 males and 457 females,ranging in age from 39 to 82 years.Clinical data and puncture-related characteristics were collected,including tumor size,puncture depth,puncture angle,presence of emphysema,lesion loca-tion in the lung,body position during puncture,whether the puncture passed through the interlobar fissure,and the number of punctures.The RF model was used to rank the importance of all variables,identifying those with the highest predictive value.Subsequently,a multivariate logistic regression model was applied to the top-ranked important variables to further e-valuate their independent impact on postoperative pulmonary hemorrhage.Results The RF model results showed that tumor size and puncture depth had the highest importance in predicting the risk of postoperative pulmonary hemorrhage.Multivari-ate logistic regression analysis further confirmed that smaller tumor size(HR:0.980,95％CI:0.971-0.989,P＜0.05)was significantly associated with a lower risk of hemorrhage,while greater puncture depth(HR:1.146,95％CI:1.063-1.235,P＜0.05)was closely related to a higher risk of hemorrhage.Additionally,other factors such as puncture angle,age,lesion location in the lung and presence of emphysema showed some influence but did not reach statistical significance in the multi-variate analysis.Conclusion This study successfully identified tumor size and puncture depth as independent risk factors for postoperative pulmonary hemorrhage by combining the RF model with multivariate logistic regression analysis.The appli-cation of the RF model improved the accuracy of feature selection,allowing us to focus on the most contributory predictive variables.These findings provide important support for preoperative risk assessment,suggesting that clinicians should priori-tize these key factors in preoperative evaluations to develop safer and more effective surgical plans,thereby reducing the risk of postoperative hemorrhage and other complications.

Ovarian cancer is a common malignant tumor in the female reproductive system,and its pathogenesis and regulato-ry mechanisms are extremely complex and still unclear.Fatty acid metabolism mainly involves the processes of fatty acid uptake,syn-thesis,and oxidation.Previous studies have shown that fatty acid metabolism plays a unique role in the occurrence and development of ovarian cancer.Therefore,this article reviews existing literature and delves into the correlation between fatty acid metabolism and ovarian cancer,aiming to provide new perspectives and reflections on the mechanism of fatty acid metabolism and targeted treatment of ovarian cancer.

Objective: To explore periodontal health knowledge and behavior among adolescents aged 12-15 years in Henan Province so as to provide scientific basis for oral health care. Methods: According to the basic methods of the Fourth National Oral Health Survey, 3 786 school adolescents, aged 12-15 years, were selected from 12 middle schools in two district and two country in Henan by multi-stage stratified equal capacity random sampling. Oral examination and a questionnaire survey were performed among these students. Results: The rate of periodontal health was 6.08%, the prevalence of gingival bleeding in these adolescents was 93.92%, its calculus existence was 90.99%. The rate of brushing teeth was 77.79%. However, the rate of brushing teeth twice or more per day was 17.56%, the rate of using fluoride toothpaste was 4.57%. The rate of periodontal health of adolescents who brushing teeth, using fluoride toothpaste were higher than adolescents who did not brush teeth, did not use fluoride toothpaste (χ2=10.81, 5.96, P<0.05). The recognition of oral care knowledge was 62.31%; except for "bacteria can cause dental caries", the awareness rate of other related periodontal diseases is more than 50.00%. Conclusion The status of periodontal health among adolescents aged 12-15 in Henan Province was not optimistic. Adolescents are lake of knowledge and health behavior towards periodontal health, The promotion of adolescents’s oral health education should be strengthened.
