The Yin-Fire theory is the core content of Li Dongyuan's academic thought and has profound and extensive clinical guidance value.This paper analyzes the connotation and background of the Yin-Fire theory,and proposes that the core pathogenesis of Yin-Fire syndrome is qi deficiency without movement,and stagnation turning into fire;qi deficiency without rise,and dampness and turbidity flowing downward;qi deficiency without astringent,and Xiang-Fire rushing upward;qi deficiency and fire hyperactivity,which hurts body fluid and burns blood.This article summarizes the key points of diagnosis and treatment of various diseases by sorting out the commonly used prescriptions and medicines of Yin-Fire theory and its clinical application in miscellaneous internal medicine diseases,and deepens the understanding of the connotation of Yin-Fire syndrome.

Objective:To explore the effect of discharge preparation service based on timing theory on the care readiness and benefit finding of caregivers for elderly dementia patients.Methods:From January 2021 to December 2022, 100 caregivers of elderly dementia patients from the Neurology Department and Rehabilitation Department of Jingjiang People's Hospital were selected as the subject by convenient sampling. Caregivers were divided into a control group and a study group based on their enrollment time, with 50 cases in each group. The control group received routine nursing, while the study group was treated with discharge preparation services based on timing theory. The effect was evaluated using the Caregiver Preparedness Scale (CPS) and Caregiver Benefit Finding Questionnaire.Results:After intervention, the CPS score of the study group was (22.80±2.83), which was higher than the control group's (17.92±2.60), and the difference was statistically significant ( P<0.05). After three months of discharge, the score of the Caregiver Benefit Finding Questionnaire in the study group was (117.50±6.25), which was higher than the control group's (109.98±9.89), and the difference was also statistically significant ( P<0.05) . Conclusions:The discharge preparation service based on timing it right can improve the care readiness and benefit finding of caregivers for elderly dementia patients.

BACKGROUND: Endocrine therapy (ET) and ET-based regimens are the preferred first-line treatment options for hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer (HR+/HER2- MBC), while chemotherapy (CT) is commonly used in clinical practice. The aim of this study was to investigate the efficacy and clinical outcome of ET and CT as first-line treatment in Chinese patients with HR+/HER2- MBC. METHODS: Patients diagnosed with HR+/HER2-MBC between January 1st, 1996 and September 30th, 2018 were screened from the Chinese Society of Clinical Oncology Breast Cancer database. The initial and maintenance first-line treatment, progression-free survival (PFS), and overall survival (OS) were analyzed. RESULTS: Among the 1877 included patients, 1215 (64.7%) received CT and 662 (35.3%) received ET as initial first-line treatment. There were no statistically significant differences in PFS and OS between patients receiving ET and CT as initial first-line treatment in the total population (PFS: 12.0 vs. 11.0 months, P = 0.22; OS: 54.0 vs . 49.0 months, P =0.09) and propensity score matched population. For patients without disease progression after at least 3 months of initial therapy, maintenance ET following initial CT (CT-ET cohort, n = 449) and continuous schedule of ET (ET cohort, n = 527) had longer PFS than continuous schedule of CT (CT cohort, n = 406) in the total population (CT-ET cohort vs. CT cohort: 17.0 vs . 8.5 months; P <0.01; ET cohort vs . CT cohort: 14.0 vs . 8.5 months; P <0.01) and propensity score matched population. OS in the three cohorts yielded the same results as PFS. CONCLUSIONS ET was associated with similar clinical outcome to CT as initial first-line treatment. For patients without disease progression after initial CT, switching to maintenance ET showed superiority in clinical outcome over continuous schedule of CT.

Objective:To construct and validate a predictive model for the risk of excessive blood loss in pa-tients with ruptured tubal pregnancy,and to provide a basis and tool for the assessment of changes in the condi-tion of patients with ruptured tubal pregnancy.Methods:Clinical data of inpatients with ruptured tubal pregnancy from January 2014 to July 2021 were retrospectively analyzed,who underwent surgical treatment in the Depart-ment of Gynecology,Dongguan Maternal and Child Health Hospital.The pelvic blood volume was categorized into excessive blood loss and non-excessive blood loss groups based on whether the amount of pelvic blood was found to be≥750 ml intraoperatively.Factors influencing the occurrence of excessive blood loss were screened and modeled by univariate analysis,Lasso regression,and multi-factor Logistic stepwise regression.The area un-der the subject working characteristic curve(AUC)was used to evaluate the discrimination of the predictive mod-el,the model's consistency was evaluated by calibration curve and goodness-of-fit test,and the clinical utility of the model was evaluated and validated by the decision analysis curve.Finally,column line plots were drawn.Results:①A total of 386 patients with ruptured tubal pregnancy were included,of whom 124(32.12%)had blood loss≥750 ml.②The optimal predictors for predicting concomitant blood loss in patients with ruptured tubal preg-nancy were screened,including:days of abdominal pain,dizziness,pallor,fatigue,the maximum diameter of para-metrial mass,human chorionic gonadotropin(β-hCG),and hemoglobin(Hb)and the model and the column line graphswere constructed accordingly.③The prediction model AUC was 0.827(95%CI 0.781-0.873);the cut-off value was 0.391,at which point the specificity and sensitivity were 68.55%and 84.35%,respectively,and the AUC validated within the model by resampling was 0.804.Clinical decision curves showed that the threshold probability intervals for the maximum net benefit values ranged from 8.5%-97%,respectively.Conclusions:The constructed prediction model was validated to suggest good discriminatory efficacy and degree of consistency.As a tool,it has clinical application value in predicting the risk of hemorrhage in patients with ruptured tubal pregnan-cy.It can help to determine the occurrence of adverse events such as hemorrhagic shock at an early stage and improve the success rate of rescue treatment.

BACKGROUND: Metastasis is the main cause of tumor-associated death and mainly responsible for treatment failure of breast cancer. Autophagy accelerates tumor metastasis. In our work, we aimed to investigate the possibility of microRNAs (miRNAs) which participate in the regulation of autophagy to inhibit tumor metastasis. METHODS: MiRNA array and comprehensive analysis were performed to identify miRNAs which participated in the regulation of autophagy to inhibit tumor metastasis. The expression levels of miR-3653 in breast cancer tissues and cells were detected by quantitative real-time polymerase chain reaction. In vivo and in vitro assays were conducted to determine the function of miR-3653. The target genes of miR-3653 were detected by a dual luciferase reporter activity assay and Western blot. The relationship between miR-3653 and epithelial-mesenchymal transition (EMT) was assessed by Western blot. Student's t -test was used to analyze the difference between any two groups, and the difference among multiple groups was analyzed with one-way analysis of variance and a Bonferroni post hoc test. RESULTS: miR-3653 was downregulated in breast cancer cells with high metastatic ability, and high expression of miR-3653 blocked autophagic flux in breast cancer cells. Clinically, low expression of miR-3653 in breast cancer tissues (0.054 ± 0.013 vs . 0.131 ± 0.028, t  = 2.475, P  = 0.014) was positively correlated with lymph node metastasis (0.015 ± 0.004 vs . 0.078 ± 0.020, t  = 2.319, P  = 0.023) and poor prognosis ( P  < 0.001). miR-3653 ameliorated the malignant phenotypes of breast cancer cells, including proliferation, migration (MDA-MB-231: 0.353 ± 0.013 vs . 1.000 ± 0.038, t  = 16.290, P  < 0.001; MDA-MB-468: 0.200 ± 0.014 vs . 1.000 ± 0.043, t  = 17.530, P  < 0.001), invasion (MDA-MB-231: 0.723 ± 0.056 vs . 1.000 ± 0.035, t  = 4.223, P  = 0.013; MDA-MB-468: 0.222 ± 0.016 vs . 1.000 ± 0.019, t  = 31.050, P  < 0.001), and colony formation (MDA-MB-231: 0.472 ± 0.022 vs . 1.000 ± 0.022, t  = 16.620, P  < 0.001; MDA-MB-468: 0.650 ± 0.040 vs . 1.000 ± 0.098, t  = 3.297, P  = 0.030). The autophagy-associated genes autophagy-related gene 12 ( ATG12 ) and activating molecule in beclin 1-regulated autophagy protein 1 ( AMBRA1 ) are target genes of miR-3653. Further studies showed that miR-3653 inhibited EMT by targeting ATG12 and AMBRA1 . CONCLUSIONS Our findings suggested that miR-3653 inhibits the autophagy process by targeting ATG12 and AMBRA1 , thereby inhibiting EMT, and provided a new idea and target for the metastasis of breast cancer.

Objective:To investigate the clinical manifestations, imaging features and prognosis of posterior reversible encephalopathy syndrome with spinal cord involvement (PRES-SCI).Methods:The clinical data of 1 patient with PRES-SCI admitted to the Department of Neurology of the First Affiliated Hospital of Zhengzhou University in November 2021 were analyzed, and the data of 38 patients with PRES-SCI reported in domestic and foreign databases and this patient were collected for pooled analysis.Results:The main clinical manifestations of 39 PRES-SCI patients (including this patient) included headache (79.5%, 31/39), visual disturbance (79.5%, 31/39), vomiting (46.2%, 18/39), disturbance of consciousness (38.5%, 15/39), limb weakness (28.2%, 11/39) and seizure (23.1%, 9/39). There were up to 97.4% (38/39) of patients who had significantly elevated blood pressure. The imaging feature was long-segment spinal cord lesion involving central gray matter. Approximately 89.7% (35/39) of the spinal cord lesions originated from the junction of the medulla oblongata and the cervical spinal cord. The median number of abnormal spinal cord segments corresponding to the vertebral body was 9 (the shortest was 4 and the longest was the entire spinal cord). Thirty-eight patients had brain lesions, and the most frequently involved sites were medulla oblongata (82.1%, 32/39), occipital lobe (46.2%, 18/39), pons (43.6%, 17/39), parietal lobe (41.0%, 16/39), and cerebellum (38.5%, 15/39). Among 38 patients completing the follow-up, 31 patients (81.6%) were clinically recovered.Conclusions:Posterior reversible encephalopathy syndrome could involve the spinal cord. For patients with long-segment spinal cord lesions and significantly increased blood pressure or other risk factors, PRES-SCI should be considered. Timely identification and treatment could make most patients recovery.

Objective:To explore the obstacle factors and promoting factors of exercise guidance and implementation after breast cancer surgery, so as to provide reference and basis for the formulation of exercise program after breast cancer patients.Methods:Using the objective sampling method, a total of 10 medical staff and 10 patients with breast cancer after operation from the breast surgery department of the Seven People's Hospital Affiliated to Shanghai University of Traditional Chinese Medicine hospital in Shanghai were selected as research objects from July to September 2022. A semi-structured interview was conducted. The interview outline was developed based on the knowledge transformation framework, and the results were analyzed by the content analysis method.Results:The study extracted three levels of influencing factors. The system level included caregiver workload, educational materials, norms and responsibilities and trust in evidence-based evidence. The practitioner level included the level of exercise knowledge, the concern about patient compliance and the emphasis on exercise. The patient level included sports knowledge level, personality and interest, venous line, adverse reaction of treatment, psychological state, weather environment, attention to health and concern of family members.Conclusions:The medical staff need to consider the postoperative exercise guidance for breast cancer patients from the department, themselves and patients, and should fully consider the patients' conditions and subjective experience to improve the patients' exercise compliance.

OBJECTIVE To sort out and analyze the expression and provisions of drug standards in the text of the newly revised Drug Administration Law ，and to explore the connotation and legal positioning of drug registration standards so as to provide reference for the rational application and interpretation of relevant provisions of drug standards in Drug Administration Law . METHODS Through the review of the evolution of drug standard management in China ，the legal provisions of drug standard in the Drug Administration Law were analyzed. Comparative study and literature research methods were used to analyze the legal expression and connotation of drug standards. RESULTS & CONCLUSIONS There were different expressions about “national drug standards ”“drug standards ”and“quality standards ”in the current provisions of the newly revised Drug Administration Law ； the legal position of the provincial-level standard for the preparation of Chinese herbal pieces was not clear ，and there may be insufficient legal regulation in the enforcement of drug administration. It is necessary to make an administrative interpretation for the content of relevant drug standards and provisions ，and further clarify the legal attributes of drug standards in the processing of provincial Chinese herbal pieces in order to promote the standardized management of Chinese herbal pieces.

Objective:To explore the risk factors of spontaneous rupture of hepatocellular carcinoma (HCC), and to analyze the prognosis of transcatheter arterial embolization (TAE) in the treatment of spontaneous rupture of HCC.Methods:From January 2008 to December 2018, at Tianjin Third Central Hospital, 126 patients diagnosed with spontaneous rupture of HCC (spontaneous rupture group) and in the same period 252 patients diagnosed as HCC without rupture (non-spontaneous rupture group) were retrospectively selected. Independent sample t test, Mann-Whitney U test and chi-square test were used to compare the general data, laboratory test results and imaging results between spontaneous rupture group and non-spontaneous rupture group. Multivariate logistic regression was used to analyze the independent risk factors of spontaneous rupture of HCC. Kaplan-Meier method and log-rank test were used for survival analysis of 92 patients treated with TAE and 31 patients treated with conservative treatment in patients with spontaneous rupture of HCC, and multivariate Cox proportional hazard regression was used to analyze the independent prognostic factors of patients treated with TAE. Results:The proportions of tumor maximum diameter ≥5 cm, tumors mainly located in segment Ⅱ, Ⅲ, Ⅳ and Ⅵ of the liver, tumors protruding height from the surface of liver ≥1 cm, liver cirrhosis and portal vein thrombosis (PVT) in spontaneous rupture group were all higher than those in non-spontaneous rupture group (46.8%, 59/126 vs. 35.7%, 90/252; 61.1%, 77/126 vs. 46.0%, 116/252; 73.0%, 92/126 vs. 18.7%, 47/252; 81.7%, 103/126 vs. 69.0%, 174/252; 20.6%, 26/126 vs. 11.5%, 29/252), and the level of fibrinogen is lower than that in non-spontaneous rupture group ((3.07 ±1.38) g/L vs. (3.92±1.13) g/L), and the differences were statistically significant ( χ2=4.343, 7.644, 106.780, 6.918 and 5.628, t=-3.276, all P<0.05). The results of multivariate logistic regression analysis showed that the location of tumors in segment Ⅱ, Ⅲ, Ⅳ, Ⅵ of the liver, the height of tumors protruding from the surface of liver ≥1 cm, liver cirrhosis and the fibrinogen was lower than the lower limit of the reference value were independent risk factors of spontaneous rupture of HCC (odds ratio ( OR)=1.354, 5.726, 1.152, 1.892; 95% confidence interval ( CI) 1.062 to 2.008, 1.049 to 19.575, 1.016 to 1.895, 1.267 to 3.346; all P<0.05). Among 92 patients with spontaneous rupture of HCC treated with TAE, the TAE technical success rate and clinical success rate were 100.0% (92/92) and 93.5% (86/92), respectively. Thirty-one patients received conservative treatment. The median survival time of the patients treated with TAE was 243 d (38 d, 377 d), which was about 10 times that of the patients who accepted conservative treatment (23 d (9 d, 51 d)). The 1-month, 3-month, 6-month, 1-year and 3-year survival rates of the patients treated with TAE were 72.8%, 50.8%, 46.0%, 31.1% and 13.6%, respectively, and those of patients who accepted conservative treatment were 25.8%, 17.2%, 11.5%, 5.7% and 0, respectively; and the differences in survival rates between the two groups were statistically significant ( χ2=34.606, P<0.01). Log-rank test analysis showed that initial hemoglobin <60 g/L, C grade of liver function, total bilirubin (TBil)≥50 μmol/L, complicated with portal vein tumor thrombus, hepatic lobe embolism during TAE, and tumor maximum diameter ≥10 cm were all correlated with poor survival rates of patients with spontaneous rupture of HCC after TAE ( χ2=3.752, 4.146, 22.318, 4.087, 5.685 and 7.893, all P<0.05). The results of multivariate Cox proportional hazard regression analysis showed that TBil ≥ 50 μmol/L, hepatic lobe embolism during TAE, and tumor maximum diameter ≥10 cm were independent factors of poor prognosis of spontaneous rupture of HCC treated with TAE ( OR=25.873, 8.415, 18.620; 95% CI 4.916 to 126.005, 1.136 to 27.319, 2.754 to 84.368; all P<0.05). Conclusions:In HCC patients with tumors located in segments Ⅱ, Ⅲ, Ⅳ and Ⅵ of the liver, the height of tumors protruding from the surface of liver ≥1 cm, liver cirrhosis or the fibrinogen is lower than the lower limit of the reference value, close attention should be paid to the risk of spontaneous tumor rupture. TAE is an effective treatment for acute spontaneous rupture of HCC, and the prognosis of patients treated with TAE is better than that of patients receiving conservative treatment. However, patients with TBil ≥50 μmol/L, hepatic lobe embolism during TAE and tumor maximum diameter ≥10 cm have a poor prognosis after TAE treatment.

This paper summarizes and analyzes the current conditions of Tanzania traditional medicine practitioners, organization structure, herbal medicine resources, and the exported pharmaceutic products and related companies. The result shows that Tanzania government gradually pays the attention to the development of its own traditional medicine industry. Due to the current TCM cooperation dilemma with Tanzania, coping strategies should be adopted to provide certain references for the next stage of China-Tanzania TCM cooperation, such as adjusting the professional fields of dispatched experts, adjusting cooperative fields, including the export and investigation of TCM companies to Tanzania.
