This paper summarized professor ZHANG Boli's experience in syndrome differentiation and treatment of metabolic syndrome （MetS） based on the theory of "diseases related to damp， turbidity， phlegm， and rheum". It is considered that damp， turbidity， phlegm， and rheum are the key pathological factors in the onset of MetS. The core pathogenesis of this disease includes the failure of the liver to govern the free flow of qi， the depletion of spleen and kidney， and the accumulation and impairment caused by damp， turbidity， phlegm， and rheum. It is important to emphasize early intervention， sequential treatment， and thorough elimination of pathogenic factors. The treatment takes fortifying the spleen and promoting middle jiao （焦）， soothing the liver and regulating qi， and tonifying the kidney to restore transformation as the fundamental principles. Furthermore， targeted treatments are implemented according to the evolution of damp， turbidity， phlegm， and rheum， including treating damp early， examining the tongue coating to eliminate turbidity， differentiating and treating concurrent phlegm， and applying warm dredging moderately. At the same time， specific medicinals are combined based on abnormal indicators such as blood glucose， blood lipids， blood pressure， and uric acid， aiming to address both root causes and symptoms simultaneously.

Objective:This study aimed to investigate the role of heat shock protein family A member 5 (HSPA5) in ferroptosis at its regulatory mechanisms in ulcerative colitis (UC), using both a dextran sulfate sodium (DSS)-induced mouse model of acute colitis and in vitro cell experiments.Methods:Differentially expressed genes in UC were identified using the GSE87466 dataset from the Gene Expression Omnibus, cross-referenced with the ferroptosis-related gene database FerrDB (version 2). A protein-protein interaction (PPI) network was constructed, identifying HSPA5 as a core hub gene. To validate its role in vivo, acute colitis was induced in C57BL/6 mice using DSS, followed by treatment with the ferroptosis inhibitor Ferrostatin-1 (Fer-1). Lipid peroxidation and ferroptosis levels were assessed by measuring malondialdehyde (MDA) and iron content in colon tissues. The expression of ferroptosis-related proteins, including prostaglandin-endoperoxide synthase 2 (PTGS2), glutathione peroxidase 4 (GPX4), ferritin light chain (FTL), activating transcription factor 4 (ATF4), and HSPA5, in addition to tight junction proteins ZO-1 and Occludin, were evaluated using immunohistochemistry and Western blotting. In vitro, an inflammatory model was established using lipopolysaccharide (LPS)-stimulated Caco-2 cells. Lentiviral knockdown of HSPA5 was performed to assess its regulatory effects on ferroptosis by assessing MDA levels, GPX4 activity, and the expression of related proteins. Statistical analyses were conducted with SPSS (version 29.1), with t-tests or one-way ANOVA for normally distributed data and the Mann-Whitney U test for ordinal data. Statistical significance was set at P<0.05. Results:Based on the PPI analysis and previous research, HSPA5 emerged as a key gene linking UC and ferroptosis. In DSS-treated mice, colonic injury was accompanied by elevated MDA levels ( t=5.72, P<0.001) and iron accumulation ( t=6.32, P<0.001). DSS also increased the expression of PTGS2 and proteins in the ATF4-HSPA5 pathway, while reducing the levels of GPX4, FTL, ZO-1, and Occludin. These findings could be partially reversed by Fer-1 (MDA: t=2.92, P<0.05; iron: t=5.84, P<0.001). In Caco-2 cells, LPS treatment elevated the expression of PTGS2, ATF4, and HSPA5, and elevated the MDA content ( t=9.63, P<0.001), while reducing the expression of FTL, GPX4, ZO-1, and Occludin, as well as GPX4 enzyme activity ( t=-11.20, P<0.001). Knockdown of HSPA5 further exacerbated these changes, significantly increasing MDA levels ( t=4.15, P<0.01), decreasing GPX4 activity ( t=-9.81, P<0.001), and altering ferroptosis-related protein expression. Conclusion:HSPA5 appears to protect against intestinal damage in UC by enhancing GPX4 expression and activity, thereby reducing ferroptosis and preserving epithelial barrier integrity through the maintenance of tight junction proteins.

Objective:To analyze the clinicopathological features of giant ovarian masses(mean diameter≥10 cm)and analyze the clinical characteristics of patients in different age groups.Methods:The clinicopathological characteristics of 311 patients diagnosed with giant ovarian masses by surgery at Nanjing Drum Tower Hospital,Affiliated Hospital of Medical School,Nanjing University from January 2014 to December 2022 were retrospectively analyzed.Patients were further stratified by age and mass size to compare the differences of clinical and patho-logical features among different age groups and different mass diameter groups.Results:①The median age of thepatients were 44(24,60)years old.The first symptoms were as follows:ovarian mass discovered during physi-cal examination,abdominal pain,bloating,conscious abdominal distension,and symptoms of compression.②The surgical methods were as follows:unilateral oophorectomy(30.5％,95/311),ovarian cystectomy(28.9％,90/311),tumor staging or cytoreductive surgery(28.0％,87/311),total hysterectomy with bilateral adnexectomy(12.5％,39/311).③The pathological types were benign(49.5％,154/311),malignant(31.8％,99/311)and borderline(18.7％,58/311).④ Patients complained abdominal distension in＜20 years old group were signifi-cantly higher than the other two groups(P＜0.05).The ovarian resection rate in the＞50-year-old group was higher than that of the other two groups(P＜0.05),and the rate of unilateral ovarian resection in the＜20-year-old group was still as high as 30.1％(15/49).⑤ The size of the mass correlated with the duration of the disease.When the disease course was between 1 to 6 months,the mass diameter line＞30 cm was the most common(P＜0.05).The incidence of borderline tumors in the＞30 cm group was significantly higher than that in the other two groups,and the difference was statistically significant(P＜0.05).Conclusions:Ovarian mucinous and mucinous borderline tumors are the most common types of giant adnexal masses.The size of the mass tends to increase with the prolongation of the disease course.The incidence of borderline tumors increases with the in-crease of mass.Health education for young people should be strengthened.When abdominal pain,abdominal bloating,especially lower abdominal distension occurs,they should seek medical treatment in time to avoid adnex-ectomy due to borderline tumors.

Objective To investigate the prognostic value of N6-methyladenosine (m⁶A) modification related genes and immune infiltration in colorectal cancer (CRC) and construct a risk model for predicting outcome of patients. Methods The transcriptome data and matched clinical information of CRC patients were downloaded from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database. The prognostic value of m⁶A modification related genes and immune infiltration were investigated using the consensus clustering method and single sample gene set enrichment analysis. The weighted gene co-expression network analysis (WGCNA) was used to identify prognostic genes related with m⁶A modification and immune infiltration. Lasso regression analysis was used to construct a multi-gene risk model. The expression differences of prognostic genes identified were further validated through expression differential analysis in the Gene Expression Profiling Interactive Analysis (GEPIA) database. Finally, the Kaplan-Meier was used to evaluate the predicting performance of the model in different subgroups and external validation cohorts. Results Both the m⁶A modification and immune infiltration phenotype could effectively stratify the prognosis of CRC patients from the TCGA cohort. Most m⁶A modification related genes were significantly correlated with immune infiltration in CRC tissues. Four following prognostic genes were selected using the WGCNA method combined with Lasso regression analysis: intelectin-1, lymphocyte antigen 6 complex locus G6D, atonal homolog 1 and matrix metalloproteinase 28. In colorectal cancer tissues, the expression levels of lymphocyte antigen 6 complex locus G6D and matrix metalloproteinase 28 exhibited significant differences compared to adjacent non-cancerous tissues (P < 0.05). The risk model constructed based on the above prognostic genes can effectively identify the potential risk population with poor prognosis in different clinical subgroups of the TCGA cohort and the GEO validated cohort. Conclusion A risk model based on m⁶A modification and immune infiltration could effectively predict the clinical outcome of CRC patients, and related prognostic genes have potential to be developed as molecular targets for CRC therapy.

This paper summarized professor ZHANG Boli's experience in treating stubborn bi （痹） with the herbal pair of Ruxiang （Olibanum）- Moyao （Myrrha）. The basic pathogenesis of stubborn bi is channel and collateral stasis and obstruction. Ruxiang and Moyao are thus used in mutual reinforcement to rectify qi and diffuse bi， activate blood and relieve pain， thereby removing static and obstructed qi and blood， unblocking the obstructed channels and colla-terals， which is especially suitable for stubborn bi caused by channel and collateral obstruction. In clinical practice， the herbal pair of Ruxiang-Moyao is used together with qi-moving and blood-activating medicinals to treat chest bi by expelling stasis and diffusing stagnation， dissipating cold and unblocking vessels. To treat long-term wither and weakness in late stage of stroke， the medicinals of boosting qi and invigorating blood， unblocking channels and venting collaterals can be added to the herbal pair so as to soothe and drain vessels and collaterals， harmonize and regulate qi and blood. Simiao Yongan Decoction （四妙勇安汤） can be integrated in the treatment of vessel bi by moving qi and dissolving stasis， and for the long-term stubborn vessel bi， integrated internal and external treatment is suggested by external use of Ruxiang-Moyao to vent bi with aromatics. Moreover， it is emphasized to use the herbal pair of Ruxiang-Moyao in accordance with indications and cautions.

Recent studies have found that the brain-gut-microbiome axis(BGMA)is closely related to the occurrence and development of Alzheimer's disease(AD). BGMA can affect AD in various aspects such as neuro-immune regulation and intestinal microflora, and is a potential new target for the treatment of AD.The "Sanjiao" acupuncture method is proposed by professor Han Jingxian, a famous Chinese medicine practitioner, based on his theory of "dysfunction of Qi activity of Sanjiao leads to aging" , and has been widely used in the treatment of AD and other age-related diseases in clinical practice.This article reviews the theory of "dysfunction of Qi activity of Sanjiao leads to aging" and the relationship between the "Sanjiao" acupuncture method and BGMA, with the hope that the "San Jiao" acupuncture method can become a new target for treatment of AD in the future.

Objective To quantify the setup errors for the different anatomical sites of patients who received intensity-modulated radiotherapy (IMRT) with linear accelerator on-board kilovolt fan beam CT(kV-FBCT) as non-isocenter IGRT and megavolt cone beam CT (MV-CBCT) as isocenter IGRT. Methods A retrospective analysis was performedon 70 patients who underwent radiotherapy, kV-FBCT, and/or MV-CBCT scans after each routine setup prior to IMRT. The average displacement (M), systematic error (Σ), and random error (б) at different treatment sites in the left-right, anterior-posterior, and cranial-caudal directions were calculated according to the individual displacements. The formula 2.5Σ+0.7б was used to estimate the PTV margin in respective direction. For each single patient, the root mean square in three directions was used as 3D displacement. Results A total of 1130 displacements were recorded in the 70 patients. The PTV margin was estimated to be 1.9-3.1 mm in head and neck cancer, 2.8-5.1 mm in thoracic cancer, 4.6-5.1 mm in breast cancer, 3.0-5.5 mm in upper abdominal cancer, and 3.5-6.8 mm in pelvic tumor. For the 3D mean displacements, the head and neck, thoracic, breast, upper abdominal, and pelvic cancer were 2.4±1.0, 4.0±1.6, 4.1±2.0, 4.6±2.1, and 4.6±2.1 mm, respectively. The average 3D displacement obtained by kV-FBCT and MV-CBCT were 4.1 and 3.4 mm, respectively (P=0.212). Conclusion The quantitative setup-error data can be obtained using linear accelerator on-board FBCT, and the non-isocenter IGRT induced set-up error cannot be negligible.

OBJECTIVE To study the neuroprotective effects of Shenzao jianna o oral liquid （SZJN）on Alzheimer ’s disease （AD）model mice and its mechanism. METHODS The mice were randomly divided into sham operation group ，model group ， Donepezil hydrochloride tablet group （0.65 mg/kg），SZJN low-dose ，medium-dose and high-dose groups （0.3，1.5 and 7.5 g/kg， calculated by crude drug quantity ），with 12 mice in each group ，half male and half female. Each group was given relevant medicine（intragastric administration of water at constant volume in sham operation group and model group ），twice a day ，for consecutive 28 d. On the 15th day of administration ，intracerebroventricular injection of β-amyloid 1-42（Aβ1-42）combined with intraperitoneal injection of scopolamine hydrobromide were used to induce AD model. Morris water maze was used to detect the learning and memory ability of mice. HE staining and Nissl staining were used to evaluate the pathological changes of brain tissue in mice. The levels of MDA and SOD in brain tissue of mice were detected. The phosphorylation level of cyclic adenosine monophosphate response element binding protein （CREB） and expression of brain-derived neurotrophic factor （BDNF） in hippocampal tissues were detected by Western blot. RESULTS Compared with sham operation group ，the escape latency of the model group was significantly prolonged ，and the number of crossing the platform and the percentage of residence time in the target quadrant were significantly reduced （P＜0.01）. The level of SOD in brain tissue ，the phosphorylation level of CREB and the expression level of BDNF in hippocampus decreased significantly （P＜0.01），while the level of MDA increased significantly （P＜ 0.01）. In hippocampal CA 1 area and cortical tissue ，nerve cells showed significantly decreased number ，the disordered arrangement and large gap ；the shape of nucleus was irregular and deeply stained ，and Nissl body was blurred ，loosely arranged and the number decreased. Compared with model group ，the escape latency of mice in each dose group of SZJN was significantly shortened ，and the times of crossing the platform and the percentage of residence time in the target quadrant were significantly jing- increased（P＜0.01）. Above indexes of brain tissue in mice were reversed sig nificantly in SZJN high-dose group （P＜0.01），and pathological damage of brain tiss ue was improved. CONCLUSIONS SZJN can significantly improve the learning and memory ability of AD model mice ，and alleviate the pathological injury and oxidative stress of brain tissue ，which may be related to the activation of CREB/BDNF signaling pathway.

Objective:To observe the effect of customized orthotic insoles on the gait and balance of hemiplegic stroke survivors.Methods:Sixty stroke survivors with gait abnormalities were randomly divided into a group fitted with ankle foot orthoses (AFO) ( n=30) and a group who received customized orthotic insoles ( n=30). All received conventional rehabilitation training for 4 weeks. Before the fitting, as well as 8 hours and 4 weeks afterward, both groups were evaluated using the Tinetti gait scale (TGS), the plantar pressure balance index, the difference in length between their right and left step, step width, the Timed Up and Go test (TUGT), the Fugl-Meyer lower extremity assessment (FMA-LE), the 6-minute walk test (6MWT), a trunk impairment scale (TIS), the Berg Balance Scale (BBS) and the Barthel Index (BI). Results:At 8 hours after the fitting all of the insole group′s measurements were better than those of the AFO group, on average, but the differences were not statistically significant. After 4 weeks the average TGS, balance index barefoot and wearing the orthosis, step length difference, BBS and BI of the insoles group were significantly better than the AFO group′s averages. The other indicators were not significantly different.Conclusions:Customized orthotic insoles are more effective than an AFO in relieving the biomechanical abnormalities in hemiplegic patients′ feet and ankles, and enhancing their balance and gait.
