ObjectiveTo establish a model that can quickly identify the aroma components in different parts of Nardostachys jatamansi, so as to provide a quality control basis for the market circulation and clinical use of N. jatamansi. MethodsHeadspace solid-phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS) combined with Smart aroma database and National Institute of Standards and Technology(NIST) database were used to characterize the aroma components in different parts of N. jatamansi, and the aroma components were quantified according to relative response factor(RRF) and three internal standards, and the markers of aroma differences in different parts of N. jatamansi were identified by orthogonal partial least squares-discriminant analysis(OPLS-DA) and cluster thermal analysis based on variable importance in the projection(VIP) value >1 and P<0.01. The odor data of different parts of N. jatamansi were collected by Heracles Ⅱ Neo ultra-fast gas phase electronic nose, and the correlation between compound types of aroma components collected by the ultra-fast gas phase electronic nose and the detection results of HS-SPME-GC-MS was investigated by drawing odor fingerprints and odor response radargrams. Chromatographic peak information with distinguishing ability≥0.700 and peak area≥200 was selected as sensor data, and the rapid identification model of different parts of N. jatamansi was established by principal component analysis(PCA), discriminant factor alysis(DFA), soft independent modeling of class analogies(SIMCA) and statistical quality control analysis(SQCA). ResultsThe HS-SPME-GC-MS results showed that there were 28 common components in the underground and aboveground parts of N. jatamansi, of which 22 could be quantified and 12 significantly different components were screened out. Among these 12 components, the contents of five components(ethyl isovalerate, 2-pentylfuran, benzyl alcohol, nonanal and glacial acetic acid,) in the aboveground part of N. jatamansi were significantly higher than those in the underground part(P<0.01), the contents of β-ionone, patchouli alcohol, α-caryophyllene, linalyl butyrate, valencene, 1,8-cineole and p-cymene in the underground part of N. jatamansi were significantly higher than those in the aboveground part(P<0.01). Heracles Ⅱ Neo electronic nose results showed that the PCA discrimination index of the underground and aboveground parts of N. jatamansi was 82, and the contribution rates of the principal component factors were 99.94% and 99.89% when 2 and 3 principal components were extracted, respectively. The contribution rate of the discriminant factor 1 of the DFA model constructed on the basis of PCA was 100%, the validation score of the SIMCA model for discrimination of the two parts was 99, and SQCA could clearly distinguish different parts of N. jatamansi. ConclusionHS-SPME-GC-MS can clarify the differential markers of underground and aboveground parts of N. jatamansi. The four analytical models provided by Heracles Ⅱ Neo electronic nose(PCA, DFA, SIMCA and SQCA) can realize the rapid identification of different parts of N. jatamansi. Combining the two results, it is speculated that terpenes and carboxylic acids may be the main factors contributing to the difference in aroma between the underground and aboveground parts of N. jatamansi.

As one of the core pathogenesis during treatment with traditional Chinese medicine,liver heat runs through different stages of liver disease. The interpretation of its meaning in different medicine categories(traditional Chinese medicine,Tibetan medicine,Mongolian medicine,Uygur medicine,Dai medicine,Yao medicine,etc.) is not unified, and the phenomena of the same name with different meanings,confusion, and misappropriation emerge. This seriously restricts the inheritance,innovation, and clinical application of traditional Chinese medicine and ethnomedicine. By tracing and analyzing liver heat, it is found that liver heat in traditional Chinese medicine is caused by disordered rest and diet, as well as internal injury due to emotional disorder, which leads to liver dysfunction, Qi stagnation, and heat turning to fire in the liver meridian. The liver heat in Tibetan medicine is caused by the accumulated heat of the liver nature and the evil heat in the liver, which stimulates the toxin of Chiba fever. The liver heat in Mongolian medicine derives from the abnormal diet and rest, making excessive Sheila accumulate in the liver and causing disease. The above etiologies are all related to diet, rest,exogenous evil,emotion,and so on, and the pathogenesis is related to the imbalance of Qi and the metabolic disorder of organs. The clinical symptoms are pain in the liver region,yellow eyes, bitter mouth, fever,digestion,and loss of appetite. The principle of treatment and compatibility of prescription are heat-based, with auxiliary detoxification. Other ethnomedicine, such as Uygur medicine, Dai medicine, Yao Medicine,Miao medicine, and She medicine do not have a clear discussion on liver heat,and their etiology, pathogenesis, treatment,and prescription are not systematic,mostly based on a single drug or proven prescriptions.Through the systematic tracing,mining,induction,analysis, and arrangement of the liver heat based on existing literature information database in China,this paper regarded syndrome as the outline and disease as the goal,clarified the similarities and differences of the pathogenesis of liver heat in traditional Chinese medicine,and determined the relationship between liver heat and liver disease and the status quo of syndrome and treatment.This review provides evidence and reference for clinical prevention and treatment,as well as drug development for liver disease.

This paper summarizes Professor AI Rudi's experience in the diagnosis and treatment of skin pruritus based on the "unity of restoring form, regulating qi, and harmonizing spirit", employing internal herbal medicine combined with external treatments. It is believed that the core pathogenesis of pruritus is the "imbalance of form, qi, and spirit", with disturbed spirit as the onset, disordered qi as the key pathogenic factor, and physical changes as the manifestation of the disease. The treatment principle follows "restoring form-regulating qi-harmonizing spirit", with a combination of internal and external therapies, and differentiation based on deficiency and excess. For excess conditions caused by pathogenic disturbances to the heart spirit, treatment is based on different patterns of wind-heat, damp-heat, and blood-heat, using Sangye (Morus alba)-Sangbaipi (Morus alba cortex)-Longchi (Draconis os) to disperse wind and clear heat, calm the spirit; Difuzi (Kochia scoparia)-Qinghao (Artemisia annua)-Tanxiang (Santalum album) to clear damp-heat and aromatically open the spirit; Mudanpi (Paeonia suffruticosa)-Chuanxiong (Ligusticum chuanxiong)-Shuiniujiao (Bubalus bubalis cornua) to cool the blood, activate circulation, and calm the spirit. For deficiency conditions caused by insufficient nourishment of the heart spirit, treatment is based on patterns of qi deficiency or blood deficiency, using Huangqi (Astragalus membranaceus)-Fuping (Lemna minor)-Wuweizi (Schisandra chinensis) to tonify the qi and stabilize the exterior; Heshouwu (Polygonum multiflorum)-Jili (Tribulus terrestris)-Shouwuteng (Polygonum multiflorum vine) to nourish the blood, moisten dryness, and calm the spirit. External treatments integrate traditional Chinese medicine therapies such as medicinal baths, gua sha, and ear acupuncture, with custom herbal wash formulas for restoring form, jojoba oil gua sha for regulating qi, and ear seed therapy using Wangbuliuxing (Vaccaria segetalis) for harmonizing the spirit, achieving a holistic treatment effect for form, qi, and spirit.

To analyze the disease burden, temporal trends, and attributable risk factors of early-onset female breast cancer (EOBC) in China and globally from 1990 to 2021. Data on the absolute numbers and crude rates of incidence, mortality, and disability-adjusted life years (DALYs) for EOBC (diagnosis age < 50 years) in China and globally were extracted from the Global Burden of Disease (GBD) 2021 database. Attributable DALY proportions for five risk factors (smoking, alcohol use, physical inactivity, high red meat consumption, elevated fasting plasma glucose) and all combined risk factors were obtained. Joinpoint regression analysis was performed to assess temporal trends in age-standardized rates, quantified by annual percentage change (APC) and average annual percentage change (AAPC). From 1990 to 2021, age-standardized incidence rates of EOBC increased significantly in both China (AAPC=2.25%) and globally (AAPC=0.64%; pairwise comparison, China's age-standardized EOBC incidence is rising rapidly and approaching global levels, while mortality and DALY rates have increased over the past decade, underscoring persistent challenges in disease control. Future efforts should prioritize expanding the coverage of breast cancer screening programs, optimizing screening protocols, and enhancing public awareness of cancer prevention to mitigate the growing burden of EOBC in China.

This paper summarizes Professor AI Rudi's clinical experience in treating skin abscesses using the method of "three parts and six methods", which emphasize a combined internal and external therapeutic approach. He identifies retained pathogenic heat in the skin as the key etiological factor and proposes treatment principles tailored to the anatomical location of the lesions. For abscesses in the upper part of the body (head, face and neck), wind-heat and blood-heat are considered dominant, and the treatment focuses on dispersing the exterior, clearing heat, cooling the blood, and reducing swelling, with custom formulations such as self-fomulated Shufeng Xiaodu Decoction (疏风消毒饮) and Jiedu Xiaozhong Decoction (解毒消肿汤). For those in the middle part of the body (chest, abdomen, back and upper limbs), constrained heat and deficiency-heat predominate, and the treatment aims to relieve internal heat stagnation, reduce swelling, and expel toxins, using formulations like self-fomulated Qinggan Jiedu Decoction (清肝解毒汤) and Xiaozhong Erchen Decoction (消肿二陈汤). For abscesses in the lower part of the body in the (buttocks, perineum and lower limbs), damp-heat and stagnant heat are the main patterns, and the strategy is to clear damp-heat and resolve blood stasis, with formulations such as self-fomulated Jiedu Simiao Powder (解毒四妙散) and Qingjie Sanyu Decoction (清解散瘀汤). External therapies are equally emphasized: for unruptured lesions, self-fomulated Wumiao Ointment (五妙膏) is used to detoxify and reduce swelling, while for ruptured lesions, Danhuang Oil (蛋黄油) is applied to promote wound healing and relieve pain.

ObjectiveTo investigate the effects of Xinjia Congrong Tusizi decoction (XJCTD) on ovarian functions in the rat model of premature ovarian insufficiency (POI) and decipher the mechanism of regulating the tumor suppressor protein (p53)/nuclear factor E2-related factor 2 (Nrf2) pathway to attenuate granulosa cell ferroptosis. MethodForty-eight SPF-grade female SD rats were randomized into control, model, low-, medium-, and high-dose (1.1, 2.2, 4.4 g·kg-1) XJCTD, and Western medicine (coenzyme Q10, 0.002 7 g·kg-1) groups, with eight rats in each group. The rat model of POI was established by gavage of triptolide (TP), and after successful modeling, each group was administrated with the corresponding drugs by gavage for 14 d. The body weight and ovarian weight of each rat were weighed and the ovarian index was calculated. The morphology of the ovarian tissue was observed by hematoxylin-eosin staining, and the proportions of growing follicles and atretic follicles were calculated. The serum levels of anti-Müllerian hormone (AMM), estradiol (E2), and follicle-stimulating hormone (FSH) were measured by enzyme-linked immunosorbent assay (ELISA). The DCFH-DA fluorescent probe was used to measure the reactive oxygen species (ROS) content in granulosa cells. The content of cellular Ferrous ion (Fe2+), lipid peroxide (LPO), malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) was detected by colorimetry. The expression of the tumor suppressor protein p53,Nrf2, solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) was determined by immunohistochemistry and Western blot. ResultCompared with the control group, the model group showed decreased ovarian weight, body weight, and ovarian index (P<0.01), reduced ovarian tissue volume and proportion of growing follicles (P<0.01), increased proportion of atretic follicles (P<0.01), lowered AMH and E2 levels and elevated FSH level in the serum (P<0.01), and elevated levels of Fe2+, ROS, LPO, and MDA (P<0.01) and lowered levels of GSH and SOD in granulosa cells (P<0.01). Moreover, the modeling up-regulated the expression of p53 (P<0.01) and down-regulated the expression of Nrf2, SLC7A11, and GPX4 (P<0.05, P<0.01) in the ovarian tissue. Compared with the model group, XJCTD increased the body weight, ovarian weight, and ovarian index (P<0.01), alleviated the pathological changes in the ovarian tissue, increased the proportion of growing follicles (P<0.01), decreased the proportion of atretic follicles (P<0.01), and reduced the content of ROS in granulosa cells (P<0.05, P<0.01). In addition, medium- and high-dose XJCTD lowered the FSH level (P<0.01) and raised E2 and AMH levels (P<0.01) in the serum, reduced the Fe2+ content (P<0.05, P<0.01), and increased the SOD content (P<0.01) in granulosa cells. High-dose XJCTD reduced the LPO and MDA content (P<0.01) and increased the SOD content (P<0.01) in the granulosa cells, down-regulated the expression of p53 (P<0.05), and up-regulated the expression of Nrf2, SLC7A11, and GPX4 in the ovarian tissue (P<0.05, P<0.01). ConclusionXJCTD may protect the ovarian function in the rat model of POI by regulating the p53/Nrf2 signaling pathway to attenuate the ferroptosis of ovarian granulosa cells.

BackgroundThere exist differences in the subjective and objective cognitive functions of patients with depressive disorder, ane there are limited research on influencing factors of such phenomenon currently. ObjectiveTo explore the differences in subjective and objective cognitive function in patients with depressive disorder as well as influencing factors, and to provide references for further understanding of cognitive impairment in patients with depressive disorder. MethodsA total of 77 patients with depressive disorder who received outpatient or inpatient treatment in the Fourth People's Hospital of Chengdu from January 13, 2022 to December 11, 2023 were selected for the study. These patients also met the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders, fifth edition(DSM-5). Various tools were employed to assess patients in this study: Montgomery-Asberg Depression Rating Scale (MADRS) for the depressive symptoms, Perceived Deficits Questionnaire for Depression (PDQ-D) and Chinese Version of Brief Neurocognitive Test Battery (C-BCT) for the subjective and objective cognitive function, Sheehan Disability Scale (SDS) for the social function, and Clinical Global Impression-Severity of Illness(CGI-SI) for the severity of patient's condition. Pearson correlation analysis was used to examine the correlation of subjective and objective cognitive function and their differences with age, years of education, MADRS total score, SDS total score, and CGI-SI score. Multiple linear regression was used to explore the influencing factors of the differences between subjective and objective cognitive function. ResultsThere was a statistically significant difference in the total PDQ-D scores and the difference of subjective and objective cognitive function (D value) between depressive patients with and without medication (t=-4.228, -2.392, P<0.05 or 0.01). There was no statistically significant correlation in subjective and objective cognitive function in patients with depressive disorder (r=-0.148, P>0.05). Negative correlations can be observed between the PDQ-D total score and age or years of education (r=-0.333, -0.369, P<0.01). The PDQ-D total score was positively correlated with MADRS total score, SDS total score and CGI-SI score (r=0.487, 0.637, 0.434, P<0.01). D value was negatively correlated with age and years of education (r=-0.411, -0.362, P<0.01), while positively correlated with MADRS total score, SDS total score and CGI-SI score (r=0.259, 0.468, 0.299, P<0.05 or 0.01). Age (β=-0.328, P<0.01) and SDS total score (β=0.409, P<0.01) were two predictive factors for D value. ConclusionThe difference between subjective and objective cognitive function among patients with depressive disorder is related to several factors including age, years of education, severity of symptoms and impairment of social function.

Objective To observe the regulatory mechanism of drug-containing serum of Jinghou Zengzhi Prescription based on qi and blood replenishing method on the expression of growth and differentiation factor 9(GDF9)and apoptosis of ovarian granulosa cells in rats with controlled ovarian hyperstimulation(COH).Methods Serum of COH rats(blank serum)and serum of COH rats gavaged by the Jinghou Zengzhi Prescription were prepared.A COH rat model was established and ovarian granulosa cells were collected.The experiment was divided into 5 groups:blank serum group,drug-containing serum group,drug-containing serum+SB203580[p38 mitogen-activated protein kinase(p38MAPK)inhibitor]group,drug-containing serum + PDTC[nuclear transcription factor κB(NF-κB)inhibitor]group,drug-containing serum + SB203580 + PDTC group.The mRNA expression levels of p38MAPK,casein kinase 2(CK2),nuclear transcription factor κB inhibitor α(IκBα),NF-κB and GDF9 were detected by real-time quantitative polymerase chain reaction(qRT-PCR),and GDF9 protein expression level was detected by Western Blot,and ovarian granulosa cell apoptosis was detected by terminal-deoxynucleoitidyl transferase mediated nick end labeling(TUNEL).Results The drug-containing serum of Jinghou Zengzhi Prescription decreased the mRNA expressions of p38MAPK and NF-κB,elevated the mRNA expressions of CK2 and IκBα,increased the mRNA and protein expression levels of GDF9,and decreased the apoptosis rate of ovarian granulosa cells in COH rats.The addition of p38MAPK inhibitor SB203580 alone and the addition of NF-κB inhibitor PDTC alone both promoted the mRNA and protein expressions of GDF9 and reduced the apoptosis rate of granulosa cells.Conclusion The drug-containing serum of Jinghou Zengzhi Prescription based on qi and blood replenishing method can promote the expression of GDF9 and inhibit the apoptosis of ovarian granulosa cells in rats with COH,and its mechanism may be related to the regulation of the expression of genes of the dual signaling pathways of p38MAPK and NF-κB.
