To summarize the clinical experience of Professor LIU Shangyi in treating pruritus vulvae. It is believed that women have the physiological characteristics of liver and kidney as the root， and their pubic area is easily attacked by wind-dampness pathogenic qi， so the core mechanism of pruritus vulvae is proposed as wind-dampness accumulation and deficiency of liver and kidney. The core treatment method is to dispel wind-dampness and nourish the liver and kidneys， and modify the Danggui Decoction （当归饮子） to form a self-prescribed Yinyang Formula （阴痒方） as the basic prescription to treat pruritus vulvaen.

Growth arrest DNA damage-inducible protein 45 β (GADD45B) has been reported to be a regulatory factor for active DNA demethylation and is implicated in the modulation of synaptic plasticity and chronic stress-related psychopathological processes. However, its precise role and mechanism of action in stress susceptibility remain elusive. In this study, we found a significant reduction in GADD45B expression specifically in the ventral, but not the dorsal hippocampal CA1 (dCA1) of stress-susceptible mice. Furthermore, we demonstrated that GADD45B negatively regulates susceptibility to social stress and NMDA receptor-dependent long-term potentiation (LTP) in the ventral hippocampal CA1 (vCA1). Importantly, through pharmacological inhibition using the NMDA receptor antagonist MK801, we provided further evidence supporting the hypothesis that GADD45B potentially modulates susceptibility to social stress by influencing NMDA receptor-mediated LTP. Collectively, these results suggested that modulation of NMDA receptor-mediated synaptic plasticity is a pivotal mechanism underlying the regulation of susceptibility to social stress by GADD45B.

High mobility group box 1 (HMGB1), when released extracellularly, plays a pivotal role in the development of spinal cord synapses and exacerbates autoimmune diseases within the central nervous system. In experimental autoimmune encephalomyelitis (EAE), a condition that models multiple sclerosis, the levels of extracellular HMGB1 and interleukin-33 (IL-33) have been found to be inversely correlated. However, the mechanism by which IL-33 deficiency enhances HMGB1 release during EAE remains elusive. Our study elucidates a potential signaling pathway whereby the absence of IL-33 leads to increased binding of P300/CBP-associated factor with HMGB1 in the nuclei of astrocytes, upregulating HMGB1 acetylation and promoting its release from astrocyte nuclei in the spinal cord of EAE mice. Conversely, the addition of IL-33 counteracts the TNF-α-induced increase in HMGB1 and acetylated HMGB1 levels in primary astrocytes. These findings underscore the potential of IL-33-associated signaling pathways as a therapeutic target for EAE treatment.

Objective To establish normal reference values for left ventricular trabecular and papillary muscle mass(TPMM)in Chinese adults using MRI and to explore its impact factors.Methods A total of 168 healthy Chinese adults were retrospectively included,and compacted and total left ventricular myocardial mass(LVM)were measured using traditional and dedicated methods,respectively.TPMM was calculated from the difference between total and compacted LVM.Independent sample t-tests and analysis of variance were used to explore the differences in TPMM among genders and age groups,while multiple linear regression was used to explore the independent correlation between TPMM and age,gender,heart rate,systolic blood pressure(SBP),fasting blood glucose(FBG),and body mass index(BMI).Results TPMM for men was significantly larger than that for female(P<0.001).TPMM in the elderly group was significantly larger in female(P<0.05),but not in men.Multiple linear regression showed that BMI and SBP were both independently positively correlated with TPMM,and female and heart rate were independently negatively correlated with TPMM(P<0.05).Conclusion This study provides age-and gender-specific normal reference values for TPMM in Chinese adults.Gender,heart rate,BMI,and SBP are all independently associated with TPMM.

This paper summarized the clinical experience of Professor HE Chengyao in treating recurrent miscarriage complicated with subclinical hypothyroidism. It is believed that kidney yang insufficiency is the root of the disease， while the functional decline of the five zang （脏） organs and the obstruction of the sanjiao （三焦） pivot are the key links of the pathogenesis. In clinical practice， the division of yang numbers in the Book of Changes （《周易》） is followed， and 9 months is advocated as the basic treatment cycle for recurrent miscarriage complicated with subclinical hypothyroidism. During the first half of the period before pregnancy （the first 3 months）， it is recommended to warm the pivot and sanjiao （三焦）， and Yougui Pills （右归丸） is commonly used as the basic prescription to warm and supplement the kidney yang， together with the medicinals of invigorating blood and dissolving stasis， regulating and unblocking qi movement. During the second half of the period before pregnancy （the second 3 months）， it is better to nourish essence and nature the embryo commonly with Wuzi Yanzong Pills （五子衍宗丸） in modification. After pregnancy （the third 3 months）， it is suggested to supplement kidney and consolidate chong mai （冲）， replenish qi and nourish blood mainly， supplemented by warming and nourishing heart yang， and self-made Bushen Antai Formula （补肾安胎方） which is modified based on the combination of Shoutai Pills （寿胎丸） and Wenbao Beverage （温胞饮） is commonly used.Additionally， it is recommended to adjust lifestyle and diet so as to balance yin and yang and improve the physical condition.

Objective:To analyze the association between zygomatic change and bone setback or resection and propose a quantitative guidance for L-shaped reduction malarplasty by linear regression analysis based on computed tomographic (CT) scan images.Methods:A retrospective observational study was conducted on patients who underwent L-shaped reduction malarplasty with mortice and tenon joint at the zygomatic arch in Department of Orthognathic and Temporomandibular Joint Surgery, West China Hospital of Stomatology, Sichuan University from January 2017 to September 2022. Bone setback and resection were performed in cases required a classical L-shaped osteoectomy with oblique bone resection (Group Ⅰ). Bone setback was performed in cases required a modified L-shaped osteotomy without bone resection (Group Ⅱ). Wound healing and the occurrence of complications were followed up after operation. The amount of bone setback and resection were calculated by using preoperative and postoperative CT scan images. The unilateral width changes of the anterior, middle, and posterior zygomatic regions(ΔZBP-MFP, ΔZMP-MFP, ΔZAP-MFP, respectively) as well as zygomatic protrusion change(Δzygomatic protrusion) were also evaluated. SPSS 20.0 software was used for statistical analysis. The measurement data was expressed as Mean±SD. Zygomatic width and protrusion change of the two groups was compared by independent t-test. Comparison of complication rates between the two groups was performed using the χ2 test. Correlation analysis using Pearson correlation coefficients was performed between bone resection or setback and zygomatic width or protrusion change. Linear regression analysis was also performed. Results:A total of 80 patients were enrolled. Group Ⅰ consisted of 40 patients [6 males and 34 females; aged (25.2±3.8) years, ranging from 19 to 33 years] who underwent a classical L-shaped osteotomy with both bone setback and resection, while Group Ⅱ consisted of 40 patients [10 males and 30 females; aged (26.0±3.0) years, ranging from 20 to 35 years] who underwent a modified L-shaped osteotomy with bone setback but without bone resection. All patients healed uneventfully during the follow-up period[(12.5±3.3) months, ranging from 5 to 20 months]. There was no significant difference in the incidence of complications such as infection, transient paresthesia, severe swelling and hematoma between the two groups ( P>0.05). No severe complications, such as facial asymmetry, sagging cheek, bone nonunion, were observed. All patients significantly improved facial contours. There was a statistically significant difference (all P<0.01) in ΔZBP-MFP [ (2.52±0.76) mm vs. (1.85±0.40) mm], ΔZMP-MFP [ (3.30±0.54) mm vs. (2.94±0.51) mm] and Δzygomatic protrusion [ (4.42±1.20) mm vs. (3.59±0.84) mm] between Group Ⅰ and Group Ⅱ. No statistical difference was found in ΔZAP-MFP ( P>0.05). Significant correlation was observed between the bone setback or resection and the changes of anterior, middle zygomatic width as well as protrusion in both the two groups ( r=0.60-0.92, all P<0.01), and the linear regression equation was established. The correlation between bone setback or resection and the posterior zygomatic width change was not significant ( P>0.05). Conclusion:There are linear correlations between the unilateral anterior, middle zygomatic width change, zygomatic protrusion change and the unilateral bone setback or resection. The linear regression equations can be used as a quantitative guidance for preoperative surgical planning.

Objective:To analyze the clinical efficacy and prognostic factors of comprehensive treatment for atypical teratoid / rhabdomyoma tumor (AT/RT).Methods:Clinical data of children diagnosed with AT/RT who underwent radiotherapy in Department of Oncology of Xinhua Hospital affiliated to Shanghai Jiao Tong University School of Medicine from November 2012 to September 2022 were retrospectively analyzed. Pearson Chi-square test or continuous-corrected Chi-square test or Fisher's exact probability method were used for inter-group comparison of categorical variables. Independent sample t-test or Wilcoxon rank-sum test were used for inter-group comparison of continuous variables. Kaplan-Meier method was used to calculate the 1-year and 2-year overall survival (OS) rate and progression free survival (PFS) rate. Univariate and multivariate Cox regression analyses were employed to determine relevant prognostic factors. Results:A total of 45 patients were included, with a male/female ratio of 1.65:1, including 27 children aged ≥3 years old. All patients received surgery and radiotherapy in which 39 patients received chemotherapy, 41 craniospinal irradiation (CSI), and 4 whole brain or focal radiation therapy. The median follow-up was 28 (13.5, 49) months. A total of 14 patients died after comprehensive treatment. The 1-year OS rate was 80.0% and the PFS rate was 71.1%. The 2-year OS rate was 75.5% and the PFS rate was 65.7%. Survival prognostic analysis showed negative imaging assessment after radiotherapy ( HR=0.087, 95% CI: 0.011-0.697, P=0.022) was a favorable factor for PFS. The primary tumor<4.8 cm ( HR=0.221, 95% CI: 0.052-0.935, P=0.040) and CSI ( HR=0.085, 95% CI: 0.011-0.651, P=0.018) were favorable factors for OS. In subgroup analysis, CSI also improved OS in children aged ≥3 years ( HR=0.014, 95% CI: 0-0.470, P=0.017), but there was no significant difference in PFS. In children without cerebrospinal fluid dissemination, negative radiographic results after radiotherapy ( HR=0.066, 95% CI: 0.009-0.481, P=0.007; HR=0.076, 95% CI: 0.008-0.695, P=0.024, respectively) and CSI (HR=0.105, 95% CI: 0.012-0.937, P=0.044; HR=0.054, 95% CI: 0.005-0.629, P=0.020, respectively) were favorable factors for PFS and OS in children, and the primary tumor<4.8 cm also suggested a longer OS ( HR=0.094, 95% CI: 0.013-0.690, P=0.020). Conclusions:Comprehensive treatment including radiotherapy improves clinical prognosis of children with AT/RT. Our study shows that negative imaging results after radiotherapy are associated with PFS improvement. The primary tumor<4.8 cm and CSI are favorable factors for OS. CSI is also a significantly positive prognostic factor in children aged ≥3 years and those without cerebrospinal fluid dissemination.

OBJECTIVES: Hypertrophic cardiomyopathy (HCM) frequently leads to myocardial ischemia and cardiac dysfunction. Even genotype-positive/phenotype-negative (G⁺/P^-) individuals, carriers of pathogenic sarcomere gene mutations without left ventricular hypertrophy, remain at risk of progression to clinical HCM. This study aims to evaluate myocardial perfusion and contractile function in familial HCM patients and their first-degree relatives using myocardial contrast echocardiography (MCE) and velocity vector imaging (VVI), in order to identify early myocardial dysfunction and at-risk individuals within families. METHODS: Thirty-five genetically confirmed HCM patients with left ventricular hypertrophy were assigned to a G⁺/P⁺ group. A total of 30 first-degree relatives carrying sarcomere mutations but without echocardiographic evidence of left ventricular hypertrophy were assigned to a G⁺/P^- group. A total of 38 age- and sex-matched gene-negative healthy family members served as controls. All participants underwent MCE and VVI assessments. Myocardial perfusion parameters, including peak intensity (PI), time to peak concentration (TP), and the ratio of declining intensity and declining time (dI/dT), as well as strain parameters including global longitudinal strain (GLS), global radial strain (GRS), and global circumferential strain (GCS) were recorded and analyzed for differences and correlations. RESULTS: Compared to both the G⁺/P^- and normal control groups, the G⁺/P⁺ group had significantly lower PI, dI/dT, GLS, and GRS, along with significantly increased TP (all P<0.05). GLS and GRS were positively correlated with PI (r=0.629 and r=0.613, respectively; both P<0.01) and negatively correlated with TP (r=-0.597 and r=-0.571, respectively; both P<0.01). Compared to the normal control group, the G⁺/P^- group showed a significant reduction in GLS (P<0.05), but no significant differences in GRS, GCS, PI, TP, or dI/dT (all P>0.05). CONCLUSIONS Myocardial contractile dysfunction in HCM patients is closely related to impaired perfusion. Even in the absence of wall hypertrophy, sarcomere mutation carriers show early signs of subclinical left ventricular dysfunction. MCE and VVI can quantitatively assess myocardial perfusion and function, offering valuable tools for early detection and risk stratification in HCM patients and their relatives.
