ObjectiveTo analyze the differences in color, odor and volatile components of Citri Reticulatae Pericarpium(CRP) before and after being stir-fried with Halloysitum Rubrum, and to explore the material basis of enhancing the effect of strengthening spleen after processing and the scientific connotation of decoction pieces processed with Halloysitum Rubrum as the auxiliary material. MethodsThe volatile components of the samples before and after processing were identified and relatively quantified by headspace gas chromatography-mass spectrometry(HS-GC-MS), and the volatile components were analyzed by principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). According to the principle of variable importance in the projection(VIP) value>1.5, volatile differential components before and after processing were screened. And combined with intelligent sensory technologies such as colorimeter and electronic nose, the chroma and odor information of CRP before and after being stir-fried with Halloysitum Rubrum were identified. Pearson correlation analysis was used to explore the correlation between volatile differential components and chroma values. ResultsA total of 112 volatile components were identified from CRP and CRP stir-fried with Halloysitum Rubrum, of which 84 were from CRP and 97 were from CRP stir-fried with Halloysitum Rubrum. And 7 differential components were selected, including α-pinene, β-myrcene, linalool, sabinene, ocimene isomer mixture, A-ocimene, and δ-elemene. After being processed with Halloysitum Rubrum, the brightness value(L*), yellow-blue value(b*) and total chromatic value(E*ab) of CRP were decreased(P<0.01), and red-green value(a*) was increased(P<0.01), the response values of S4, S5, S10 and S13 sensors were significantly increased(P<0.05), and the response values of S3 and S8 sensors were significantly decreased(P<0.05). Correlation analysis showed that α-pinene and β-myrcene were negatively correlated with L* and E*ab, but positively correlated with a*. Sabinene was positively correlated with L* and E*ab. Linalool was positively correlated with L* and E*ab, and negatively correlated with a*. The ocimene isomer mixture was positively correlated with the L*. ConclusionAfter being processed with Halloysitum Rubrum, the appearance color, odor and volatile components of CRP change significantly, and α-pinene, β-myrcene, sabinene, linalool and A-ocimene are the characteristic volatile components before and after processing, which can provide references for the quality evaluation and clinical application of CRP and its processed products.

Lung cancer is the malignant tumor with the highest incidence and mortality rates globally. Current treatment methods for lung cancer primarily include surgery, chemotherapy, targeted therapy, and immunotherapy. However, the main limitations of these treatments are their side effects, the drug resistance, and the economic burden they impose. As a critical cancer pathway, the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathway regulates tumor occurrence and development through multiple mechanisms by influencing various downstream targets. Consequently, the JAK/STAT signaling pathway offers a promising avenue for lung cancer treatment research. Numerous studies have demonstrated that the JAK/STAT signaling pathway plays a key role in the proliferation and growth of lung cancer cells, angiogenesis, epithelial-mesenchymal transition (EMT), metabolic alterations, remodeling of the immune microenvironment, and the development of treatment resistance. Traditional Chinese medicine (TCM) has garnered increasing attention due to its minimal side effects, low economic burden, and its potential to enhance efficacy and reduce toxicity when used in conjunction with Western medicine. In addition to traditional Chinese medicine compounds, a growing number of Chinese medicine monomers have come into the spotlight because of their more targeted effects. Numerous studies investigating the regulation of the JAK/STAT signaling pathway by TCM in the treatment of lung cancer have demonstrated that TCM can inhibit the proliferation and invasion of lung cancer cells, tumor angiogenesis, and EMT, improve the inflammatory and immunosuppressive microenvironments, and enhance treatment sensitivity by intervening in the JAK/STAT signaling pathway, thereby impeding the progression of lung cancer. In recent years, the research on the regulation of this pathway by TCM in the treatment of lung cancer has been updated rapidly. However, the summary of these studies has not been updated in time. This review summarizes and reflects on the recent research findings regarding the regulation of the JAK/STAT signaling pathway by TCM to intervene in lung cancer from three aspects, introducing the JAK/STAT pathway, elaborating the mechanism of this pathway in lung cancer, and exploring the intervention of TCM in the treatment of lung cancer through this pathway, to provide more reference for the treatment of lung cancer in the future.

Pemphigus vulgaris (PV) is the most common subtype of pemphigus. It predominantly affects adults, with pediatric cases being exceedingly rare. Despite advancements in clinical treatment, the mortality rate of pediatric PV (PPV) has historically been alarmingly high, ranging from 70% to 100% in the absence of proper diagnosis and treatment. Although recent improvements in therapeutic strategies have led to a gradual decline in mortality, early and appropriate intervention remains crucial, particularly for children with acute onset and rapid disease progression, to prevent severe complications. However, due to the rarity of PPV, no standardized diagnostic and treatment guidelines are currently available. This study retrospectively analyzed 104 PPV cases recorded in the PubMed and China National Knowledge Infrastructure (CNKI) databases between 1969 and 2024, with the aim of providing insights for the standardized diagnosis and management of PPV. PPV presents with flaccid blisters affecting both cutaneous and mucosal surfaces. Upon rupture, these blisters result in painful, sharply demarcated erythematous erosions, accounting for approximately 1.4%-3.7% of all reported PV cases. The age of onset ranges from 1.5 to 18 years, with an average of 12.4 years, and no significant gender differences have been observed. In pediatric patients, the oral mucosa is typically the earliest and most frequently affected site, with an involvement rate as high as 87.3%, and it most commonly affects the buccal mucosa (27.9%). Other mucosal sites are affected in 52.9% of cases, with genital (28.8%) and perianal (6.7%) involvement being more frequent than in adult patients. Skin lesions are present in 80.4% of pediatric cases, a significantly higher rate than 16.0%-68.4% observed in adults. If lesions are relatively localized, local glucocorticoid therapy can be attempted first, with 8.3% of children achieving complete remission through local treatment alone. Systemic glucocorticoid therapy is the preferred option for cases that respond poorly to local therapy. Among these cases, 75.3% of pediatric patients were treated with prednisone, with 85.1% starting at an oral dose of 0.5-1.5 mg/kg/day, while 14.9% received an initial dose of 2 mg/kg/day. Alternative treatments, such as immunosuppressants, biologics, or other adjuvant medications, may be considered for pediatric patients who exhibit an inadequate response to glucocorticoid therapy or experience severe adverse effects. The most commonly used agents include azathioprine (24.0%), dapsone (21.7%), and rituximab (12.5%). The follow-up period for pediatric patients ranged from 1 to 120 months, with an average duration of 38 months. Prognosis in pediatric patients was more favorable compared to adults, with 43.8% achieving complete remission (cessation of treatment), 37.5% achieving partial remission (low-dose maintenance therapy), 9.6% still undergoing treatment, and only 1.1% succumbing to pneumonia or sepsis. Compared to adults, prolonged corticosteroid use in children poses a greater risk to physiological and psychological well-being, making them more susceptible to adverse effects related to growth, metabolism, and ocular health. Severe adverse reactions occurred in 22.1% of pediatric patients receiving corticosteroids, with Cushingoid facies (73.9%) and weight gain (39.1%) being the most common. In addition, 30.4% experienced growth and skeletal abnormalities, including growth retardation (17.4%), osteoporosis (8.7%), and fractures (4.3%). While PPV shares certain etiological, clinical, and histopathological characteristics with adult PV (APV), early diagnosis and timely intervention remain critical for optimal outcomes. Multidisciplinary collaboration is often necessary to ensure comprehensive management, improve treatment adherence, and safeguard the physical and psychological health of pediatric patients.

The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.

6.Effect and Mechanism of N-acetylcysteine in Ischemic Stroke
Journal of Sun Yat-sen University(Medical Sciences) 2024;45(2):190-195
Ischemic stroke (CIS) refers to ischemic necrosis or softening of localized brain tissue caused by cerebral blood circulation disorders, ischemia and hypoxia. The incidence of CIS is the highest among cerebrovascular diseases. Reduced supply of oxygen and nutrients leads to severe loss of neurons and deficits in brain function in stroke patients. Developing treatments for ischemic stroke remains an important challenge in clinical medicine. The antioxidant N-acetylcysteine (NAC) is a precursor of glutathione, and evidence from animal models of ischemic stroke and some clinical studies suggest that NAC can effectively protect the brain from ischemic damage. In this paper, the mechanism of NAC in CIS is described from various aspects, such as anti-oxidation, inhibition of inflammation, protection of cerebral nerve and mitochondrial function, stabilization of arterial plaque and thrombolytic function, aiming to explore the relationship between NAC and CIS in depth from the basic level, and to provide a theoretical basis for the further application of NAC in the prevention and treatment of patients with ischemic stroke.

Objective:To investigate the efficacy and safety of en-bloc Holmium laser enucleation of the prostate (HoLEP) with an early apical mucosa dissection technique for the treatment of benign prostate hyperplasia (BPH).Methods:The clinical data of 215 patients treated with HoLEP for BPH from January 2020 to January 2023 in the Department of Urology, Beijing Friendship Hospital, Capital Medical University were retrospectively analyzed. According to different treatment methods, the patients were divided into study group ( n=112) and control group ( n=103). Patients in the study group were treated by the en-bloc HoLEP with an early apical mucosa dissection technique, while patients in the control group were treated by the classical two or three-lobes HoLEP. The primary endpoints included the rates of urinary incontinence at 1-month, 3-month, and 6-month after surgery in two groups of patients. The secondary endpoints included operative time, hemoglobin decrease, dissected prostate weight, postoperative indwelling catheter time, postoperative hospital stay, and international prostate symptom score (IPSS), quality of life (QoL), Qmax, and postvoid residual urine (PVR) at 3-month and 6-month after surgery. The measurement data were tested by Shapiro-Wilk normality test. The normal distribution of the measurement data were expressed as mean ± standard deviation ( ± s), and independent sample t-test was used for comparison between two groups. Measurement data of skewness distribution were expressed as median (interquartile distance) [ M( Q1, Q3)], and Wilcoxon or Mann-Whitney U test were used for comparison between two groups. The count data in the two groups were compared by the Chi-square test. Results:The incidence of urinary incontinence in the study group was 9.0% (10/112) and 3.6% (4/112) at 1-month and 3-month after surgery, which was significantly lower than those in the control group [18.5% (19/103) and 11.7% (12/103)], and the differences were statistically significant ( P< 0.05). Urinary incontinence in two groups recovered completely 6-month after surgery. The operation time of the study group was (68.74±23.71) min, which was lower than that of the control group [(88.04±25.43) min], and the difference was statistically significant ( P<0.05). There were no significant differences in hemoglobin decrease, dissected prostate weight, postoperative indwelling catheter time, postoperative hospital stay in the two groups ( P> 0.05). The IPSS, QoL, Qmax and PVR of the two groups were significantly improved at 3-month and 6-month after surgery ( P< 0.05), but there was no significant difference between the two groups ( P> 0.05). Conclusion:En-bloc HoLEP with an early apical mucosa dissection technique is safe and reliable in treating BPH, and has advantages over classic HoLEP in terms of short-term urinary continence rates, shortening operation time.

Objective:To analyze the pathogen distribution and prognostic risk factors of catheter-related bloodstream infection (CRBSI) in patients with maintenance hemodialysis (MHD) during non-hospitalization.Methods:A retrospective comparative study was conducted. Thirty-four patients of MHD with semi-permanent catheter admitted to the department of nephrology of Gansu Provincial Hospital from January 2020 to May 2023 due to CRBSI during non-hospitalization were enrolled. The distribution characteristics of pathogens causing CRBSI in MHD patients during non-hospital period were analyzed. All patients were actively given anti-infection treatment after admission. The general data, laboratory indicators and prognosis during hospitalization were collected through the electronic medical record system. Patients were divided into poor prognosis group (14 cases) and good prognosis group (20 cases) according to the treatment results during hospitalization. Univariate and binary Logistic regression were used to analyze the risk factors affecting the prognosis of patients, and receiver operator characteristic curve (ROC curve) was drawn to evaluate its predictive value for prognosis.Results:A total of 28 pathogenic bacteria were isolated from 34 patients, of which 25 were Gram-positive, Staphylococcus was the most common pathogen, accounting for 82.15% of the total, and 16 strains of Staphylococcus aureus (57.15%), including 6 methicillin-resistant Staphylococcus aureus (MRSA, 21.43%). There were 7 strains of Staphylococcus epidermidis (25.00%), including 3 strains of methicillin-resistant Staphylococcus epidermidis (MRSE, 10.71%). There were 3 strains of Gram-negative bacteria, 1 strain each of Pseudomonas aeruginosa, Escherichia coli and Acinetobacter baumannii. Univariate analysis showed that the fever duration of MHD patients with CRBSI in the poor prognosis group was significantly longer than that in the good prognosis group [days: 8.50 (3.75, 45.00) vs. 2.50 (1.00, 4.75), P < 0.01], serum erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and random blood glucose (GLU) were significantly higher than those in the good prognosis group [ESR (mm/1 h): 82.36±24.98 vs. 56.95±35.65, CRP (mg/L): 123.45±74.10 vs. 67.35±55.22, GLU (mmol/L): 8.74±3.66 vs. 6.42±1.95, all P < 0.05]. Binary Logistic regression analysis showed that serum CRP was an independent risk factor for poor prognosis in MHD patients with CRBSI [odds ratio ( OR) = 1.020, 95% confidence interval (95% CI) was 1.002-1.038, P = 0.025]. ROC curve analysis showed that the area under the curve (AUC) of serum CRP in predicting poor prognosis of MHD patients with CRBSI was 0.711; when the optimal cut-off value was 104.65 mg/L, the sensitivity was 64.3% and the specificity was 85.0%, indicating that it has good predictive value. Conclusions:Gram-positive bacteria are the main pathogens of CRBSI in MHD patients during non-hospital period. The poor prognosis is mainly related to the high level of serum CRP. Serum CRP level can effectively screen the high-risk group of MHD patients with CRBSI with poor prognosis.
