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.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

[Objective]To evaluate the utility of left atrial(LA)volume and strain measured by 4D auto left atrial quantification(4D auto LAQ)in differentiating pre-capillary from post-capillary pulmonary hypertension(PH),and to compare its discriminative performance with echocardiographic pulmonary to left atrial global strain ratio(ePLAGS).[Methods]A total of ninety-eight subjects with intermediate to high probability of PH were prospectively enrolled.Clinical history and laboratory data were collected.All patients underwent comprehensive transthoracic echocardiography,and LA volume and strain parameters were measured by dedicated commercial software for LA 4D analysis.[Results]Based on pulmonary arterial wedge pressure,patients were divided into pre-capillary PH group[n=39;mean age(53±24)years]and post-capillary PH group[n=59;mean age(57±18)years].Compared to the pre-capillary PH group,the post-capillary PH group showed significantly higher LAVImax,LAVImin and LAVIpreA but markedly lower LASr and LAScd.Multivariate logistic regression identified LAVImax[OR:1.40;95%CI:(1.052,1.872);P=0.021]and LAScd[OR:1.76;95%CI:(1.183,2.489);P=0.004]as independent predictors of post-capillary PH.ROC analysis demonstrated that LAVImax(AUC=0.82,P＜0.001)and LAScd(AUC=0.78,P＜0.001)had strong discriminating power for predicting post-capillary PH group,with optimal cutoff values of 35.69 mL/m2(sensitivity 86%,specificity 74%)and-9%(sensitivity 80%,specificity70%).[Conclusion]LAVImax and LAScd measured with 4D auto LAQ are robust parameters for distinguishing pre-capillary PH from post-capillary PH.

Objective:To explore the prognostic value of peripheral blood lymphocyte subsets in patients with newly diagnosed multiple myeloma (NDMM) .Methods:The study retrospectively analyzed 133 patients with NDMM admitted to the General Hospital of Tianjin Medical University General Hospital between 2017 and 2022. The least absolute shrinkage and selection operator (LASSO) regression was used to screen the predictive subgroups from the peripheral blood lymphocyte subsets, and the optimal cutoff value was calculated through receiver operating characteristic curve analysis. A nomogram was constructed based on the results of the multiple-factor analysis, and the predictive performance of the nomogram was evaluated by the concordance index and calibration curve. Kaplan-Meier curves and log-rank tests were conducted to compare the differences in overall survival (OS) and progression-free survival between the high-risk and low-risk immune risk scores groups.Results:Using LASSO regression, the percentages and absolute counts of CD16 +CD56 + NK cells, CD3 + T lymphocytes, CD3 +CD8 + T lymphocytes, and CD3 -CD19 + B lymphocytes were selected as predictive subgroups. The immune risk score of patients with NDMM was calculated based on the coefficients of each lymphocyte subgroup. The area under the curve of the immune risk score was 0.737, and the optimal cutoff value was -1.834. Based on this, the patients were divided into high-risk and low-risk groups. Survival analysis showed a significant difference in the 3-year OS rate between the high-risk and low-risk immune risk score groups (87.4% vs 49.0%, P<0.001), and a significant difference in the 3-year OS rate between the high-risk and low-risk immune risk score groups in patients with minimal residual disease negative (100% vs 68.6%, P=0.001). Multivariate analysis showed that serum calcium ( P=0.034), high-risk cytogenetic abnormalities ( P=0.002), and immune risk score ( P<0.001) were prognostic factors for patients with NDMM, and a nomogram was constructed based on these factors. The consistency index of the nomogram was 0.793, and the calibration curve showed good predictive ability. The nomogram can accurately classify the risk of different prognostic staging systems. Conclusions:The combined analysis of lymphocyte subsets in the peripheral blood has an important value in predicting the prognosis of patients with NDMM.

Objective:To explore the correlative factors for insomnia severity in chronic insomnia patients using MemTrax memory test.Methods:Two hundred and twenty-two chronic insomnia patients (insomnia≥3 days per week with a duration≥3 months) recruited from Center for Preventive Treatment of Diseases, Guangdong Provincial Hospital of Chinese Medicine or through in-hospital advertisements from April 2024 to September 2024 were chosen. Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep quality over the last month; according to PSQI score, these patients were divided into mild insomnia group (scores of 7-10), moderate insomnia group (scores of 11-15) and severe insomnia group (scores of 16-21). MemTrax memory test was used to record the picture recognition accuracy and picture recognition reaction time, and MemTrax comprehensive index (MTx-Cp) was calculated; Patients' Health Questionnaire (PHQ-9), and Generalized Anxiety Disorder-7 scale(GAD-7) were used to evaluate the depression and anxiety status of these patients in recent 2 weeks. The clinical data, MemTrax test results, PHQ-9 and GAD-7 scores of patients with different degrees of chronic insomnia were compared. Spearman rank correlation analysis was used to investigate the correlation between insomnia severity and clinical data such as cognitive memory function in chronic insomnia patients.Results:Among the 220 chronic insomnia patients, 54 had mild insomnia, 111 had moderate insomnia, and 55 had severe insomnia. Severe insomnia patients had significantly higher percentages of those>50 years old and those using hypnotics compared with mild insomnia patients and moderate insomnia patients ( P<0.05). Compared with the mild insomnia patients and moderate insomnia patients, the severe insomnia patients exhibited significantly lower picture recognition accuracy (90%[86%, 94%], 88%[82%, 94%], 84%[78%, 92%]), significantly lower MTx-Cp (88.55±18.67, 84.41±20.93, 76.69±17.43), and significantly higher PHQ-9 score (9[6, 11], 9[6, 15], 12[8, 16], P<0.05). Moreover, severe insomnia patients had significantly longer picture recognition reaction time and higher GAD-7 score than mild insomnia patients (1.11[1.03, 1.24] s vs. 1.04[0.90, 1.15] s; 7[5, 13] vs. 6[3, 9], P<0.05). Spearman rank correlation analysis showed that insomnia severity in chronic insomnia patients was positively correlated with age, PHQ-9 score, GAD-7 score, and picture recognition reaction time, and negatively correlated with picture recognition accuracy and MTx-Cp ( P<0.05). Conclusion:Insomnia severity in patients with chronic insomnia is correlated with age, cognitive memory function, depression and anxiety.

Pulmonary sarcomatoid carcinoma(PSC)is a group of rare non-small cell lung cancers that are highly aggressive,prone to metastasis and recurrence and have poor prognosis.They are usually diagnosed at an advanced stage,when surgery is no longer an option,and are unresponsive to radiotherapy and chemo-therapy.The research found that PSC's programmed death receptor-1/programmed death receptor-ligand 1 was highly expressed and most of them had genetic mutations.Chinese medicines are widely used in clinical treatment for various malignant tumors due to their multi-targeting characteristics,low side effects,and good efficacy,demonstrating significant anti-tumor effects.Given the breakthrough success of immunotherapy and targeted therapy in recent years,the article promises to provide new ideas and targets for treating this highly malignant disease with a poor prognosis.

[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 characteristics of Hashimoto thyroiditis(HT)and Graves disease(GD),two autoimmune thyroid diseases aged 10-59 in Qingdao City from 2022 to 2024,and to provide scientific basis for making targeted prevention and treatment measures.Methods:A cross-sectional study design was adopted,based on the data of the Regional Health Information Platform in Qingdao,the con-firmed cases of HT and GD from 2022 to 2024 were included,and combined with the data of the seventh population census,the three-year and annual prevalence rates of HT and GD were calculated,and the time trend of annual prevalence was analyzed by Cochran-Armitage trend test.The distribution characte-ristics of HT and GD prevalence in different age groups and regions were analyzed,and Chi-square test was used to compare the differences between the groups.Results:The total number of HT patients among women aged 10-59 in Qingdao City from 2022 to 2024 was 40 362.The proportion of HT patients in 30-34 years old was the highest(19.83％).The proportion of HT patients in Huangdao District was the highest(17.72％).The three-year prevalence of HT was 1 206.53/100 000.In 2022-2024,the annual prevalence of HT increased significantly(P＜0.001),from 385.32/100 000 in 2022 to 1 206.32/100 000 in 2024.The three-year prevalence of HT was significantly different in age distribution(P＜0.001).The three-year prevalence of HT in 25-29 years(2 354.44/100 000)and 35-39 years(2 022.20/100 000)was higher than that in other age groups,showing a bimodal distribution.There were significant differences in the three-year prevalence of HT in different regions(P＜0.001),among which the three-year prevalence of HT in Shinan District was the highest(2 392.90/100 000),followed by Licang Dis-trict(1 492.41/100 000),and Laixi City was the lowest(659.940/100 000).The total number of GD patients was 2 095,among which the proportion of GD patients in the 35-39 age group was the highest(15.42％),and the proportion of GD patients from Jimo District was the highest(12.27％).From 2022 to 2024,the three-year prevalence rate of GD was 62.63/100 000,and the annual prevalence rate of GD showed an increasing trend(P＜0.001),from 20.33/100 000 in 2022 to 62.63/100 000 in 2024.There were significant differences in the prevalence of GD by age(P＜0.001).The three-year prevalence of GD reached the highest value in the 25-29 age group(98.90/100 000),followed by the 35-39 age group(85.21/100 000),and the lowest in the 10-14 age group(14.43/100 000).In the regional distribution,there were significant differences in the 3-year prevalence of GD(P＜0.001).Laoshan District had the highest three-year prevalence of GD(107.58/100 000),followed by Shinan District(97.83/100 000)and Huangdao District(28.92/100 000).Conclusion:The three-year pre-valence of HT and GD in females aged 10-59 years in Qingdao City from 2022 to 2024 is low,but the annual prevalence is on the rise,and the three-year prevalence of HT and GD in females aged 25-39 years is higher than that in other age groups,so it is necessary to strengthen the screening and monitoring of this population.
