This article aimed to summarize the clinical experience of treating sjögren's syndrome of yin-deficiency and heat-toxin type based on the theory of exuberance of shaoyang ministerial fire accumulating to heat toxin. It is believed that sjögren's syndrome of yin-deficiency and heat-toxin type is attributed to dysfunction of shaoyang gallbladder， disruption in the circulation of sanjiao， stagnation of qi leading to fire， and prolonged accumulation of toxins causing damage. The core disease mechanism involves shaoyang dysfunction， hyperactivity of ministerial fire， and accumulation of heat toxins. In clinical practice， the therapeutic principles focus on regulating shaoyang， stabilizing and subduing ministerial fire， enriching yin and resolving toxins. For shaoyang dysfunction with internal stagnation of heat toxins， treatment should aim to unblock shaoyang， clear fire and expel toxins， using modified Sangchai Decoction （桑柴饮）； for shaoyang transformation into fire with symptoms of wood （the gallbladder） disease， the approach involves soothing and regulating gallbladder， clearing heat and resolving toxins， using modified Chaihu Shaoyao Decoction （柴胡芍药汤）； for disordered ministerial fire with excessive heat toxins， the strategy is to rescue the sovereign fire and stabilize the ministerial fire， employing modified Xinshen Liangjiao Decoction （心肾两交汤）； for unregulated ministerial fire with disordered distribution， treatment focuses on increasing body fluids and nourishing yin， stabilizing the ministerial fire， using modified Buyin Decoction （补阴汤）.

N6-methyladenosine(m6A)is produced by methylation of the 6th nitrogen atom of ade-nine.The m6A methylation modification is the most common internal modification of RNA,and the modifica-tion process mainly relies on m6A-related enzymes,including methyltransferases,demethylases and binding proteins.The core structure of the methyltransferase complex(MTC)is methyltransferase-like 3(METTL3).The pathogenesis of osteoarthritis(OA)is intricate and complex,and various factors interact with each other.This paper summarizes the mechanism of action of m6A and related enzymes,and elaborates the pathogenesis of os-teoarthritis from the aspects of chondrocytes,proteases,cytokines and signaling pathways,emphatically intro-duces the regulatory role of METTL3 on OA in m6A methylated modification.The aim is to provide new per-spectives on the pathogenesis of osteoarthritis in order to provide new ideas and approaches for the treatment of osteoarthritis.

Objective:To explore the clinical manifestations, diagnosis and treatment methods, and prognosis of hepatic portal venous gas (HPVG).Methods:Retrospective case analysis was used in the case data of 7 patients with HPVG, who were treated in Lishui Central Hospital from January 2017 to July 2024, including 5 males and 2 females. Age ranged from 46 to 90 years, with an average age of 69 years. Abdominal pain was the first manifestation in 6 cases, and septic shock occurred in 2 cases. The initial symptoms, primary diseases, comorbidities, laboratory results, imaging examinations, treatment plans, and prognosis were analyzed. Prognostic follow-up was conducted by telephone, with the focus on whether the patient had experienced HPVG recurrence and postoperative complications. The deadline for follow-up was July 31, 2024.Results:All patients had elevated white blood cells and C-reactive protein (CRP), and prothrombin time was prolonged in 4 patients. pH and base excess decreased in 4 cases, and lactic acid increased in 5 cases. Alanine aminotransferase increased in 2 cases, and total bilirubin increased in 3 cases. Blood culture was positive in 3 cases. Contrast-enhanced abdominal CT showed clear gas shadows in the portal vein and its branches in all 7 cases, which were confined to the left liver in 4 cases and distributed in both sides of the liver in 3 cases. The primary diseases were intestinal obstruction and necrosis in 4 cases, intestinal perforation and necrosis in 1 case, inflammatory bowel disease in 1 case, and acute pancreatitis in 1 case. Five patients were complicated with hypertension, diabetes and other diseases. Two patients received surgical treatment, and the average time from surgery to diagnosis was 6.8 h. Five cases received conservative treatment, 2 cases were cured and 3 cases died, with an average time from onset to death of 21.2 h.Conclusions:Contrast-enhanced abdominal CT should be the preferred method for the diagnosis of HPVG. The primary disease and its severity should be fully evaluated in the treatment of HPVG. Patients with intestinal necrosis should undergo laparotomy as soon as possible, and enterostomy should be performed during the operation. Clinicians should strengthen the awareness of HPVG in order to improve the prognosis of patients.

Objective To investigate the curative effect of interventional therapy on postoperative multiple metastases of breast cancer.Methods A total of 15 patients with multiple metastases after breast cancer surgery were treated with interventional therapy.After comprehensive evaluation,all patients were treated with chemoembolization.The therapeutic regimen was docetaxel loaded on drug-eluting bead(DEB)combined with carboplatin,once in 1 d for 21 d,2 times in total,and then the regimen was changed to docetaxel and carboplatin combined with ordinary embolization microspheres,once in 1 d for 21 d,4 times in total.CT/MRI was performed on every 2 cycles and 1,3,and 6 months after interventional therapy to evaluate its efficacy and record adverse reactions.Results The overall remission rate(ORR)at 3 months after treatment was 75％,and the disease control rate(DCR)was 91.7％.The ORR and DCR at 6 months after treatment were 50％and 83.3％,respectively.Most of the common adverse reactions were below grade Ⅲ.Conclusion Interventional therapy for multiple metastases of breast cancer after operation has a definite short-term effect,with little adverse reactions.It is worthy of further promotion in the comprehensive treatment of postoperative metastases of breast cancer.

Objective To observe the value of artificial neural network(ANN)model based on recursive feature elimination-support vector machine(RFE-SVM)for differentiating ductal carcinoma in situ(DCIS)and DCIS complicated with microinvasion(DCISM).Methods Totally 296 female patients with single breast cancer(244 cases of DCIS and 52 cases of DCISM)were retrospectively collected as training set.Then 120 female patients with single breast cancer(87 cases of DCIS and 33 cases of DCISM)were prospectively enrolled as validation set.The general data,mammography and MRI findings were compared between sets.The optimal feature subsets for establishing ANN model were screened.Receiver operating characteristic curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficacy of ANN model for differentiating DCIS and DCISM.Results Ki-67 index,the minimum apparent diffusion coefficient(ADCmin),nuclear grade,ADCheterogeneity,maximum diameter of lesion,patient's age,P63,lesion enhancement type,calcification status and necrosis were the selected top 10 optimal feature subsets.The accuracy,sensitivity,specificity,positive predictive,negative predictive and AUC of ANN model for differentiating DCIS and DCISM was 91.55％,63.46％,97.54％,84.62％,92.61％and 0.950 in training set,respectively,while was 80.00％,69.70％,83.91％,62.16％,87.95％and 0.896 in validation set,respectively.The calibration curves of ANN model were consistent with the ideal curves in both training and validation set(P=0.355,0.480),which also expressed high clinical net benefit.Conclusion ANN model based on SVM-RFE could be used to differentiate DCIS and DCISM effectively.

Objective:To investigate the types, incidences, and clinical characteristics of shock in polytrauma patients at different stages after polytrauma.Methods:A retrospective study was conducted on polytrauma patients admitted to multiple trauma centers from June 2020 to December 2021. The inclusion criteria were patients >18 years old and treated due to polytrauma. Exclusion criteria included an admission time of more than 48 h after trauma, a history of malignancy, or metabolic, consumptive, and immunological diseases. The early stage was defined as the period of ≤48 h after polytrauma, and the middle stage was defined as the period between 48 h and 14 days. The patient’s medical history, clinical manifestations, laboratory tests, imaging examination, injury severity score (ISS), and Glasgow coma scale (GCS) were collected. The types, incidences, and clinical characteristics of shock in different stages after polytrauma were analyzed, according to the diagnostic criteria of each type of shock. The differences between the groups were compared by Student’s t test, χ2 test or Mann-Whitney U test. Results:The incidence of the early and middle stage shock after polytrauma were 73.1% and 36.4%, respectively, with statistically significant difference between stages ( P<0.01). There were significant differences in the incidence of hypovolemic shock (83.6% vs. 28.4%), distributed shock (13.7% vs. 80.9%) and cardiogenic shock (3.5% vs. 6.6%) between stages (all P<0.05). The incidence of obstructive shock (8.4% vs. 9.7%, P>0.05) was similar between stages. The incidence of undifferentiated shock was 1.6% and 1.2%, respectively. There were 9.5% patients with multifactorial shock in the early stage and 14.4% in the middle stage. Totally 7 combinations of multifactorial shock were found in different stages after polytrauma. In the early stage, the combination of HS and DS accounted the highest ratio (42.3%) and followed by HS and OS for 28.8%. In the middle stage, the combination of HS and DS was the most common (48.6%) and followed by DS and OS (24.3%). Conclusions:The incidence of shock in polytrauma patients is high. Different types of shock can occur simultaneously or sequentially. Therefore a comprehensive resuscitation strategy is significant to improve the success rate of treatment.
