Systemic lupus erythematosus （SLE） may lead to secondary gynecological and obstetric disorders such as decreased ovarian reserve function， menstrual abnormalities， and adverse pregnancy outcomes. Based on "bi （痹） of both body and viscera" theory， this paper proposed that the core mechanism of SLE secondary gynecological and obstetric diseases lies in the mutual transformation between "body bi" and "viscera bi"， which together affect the uterus. Physiologically， uterus forms an internal-external network with the body and viscera through the meridians and blood vessels. Pathologically， when the healthy qi is deficient， nourishment of the body and viscera is impaired； when toxins and stasis accumulate， pathogenic factors disturb the uterus through the chong （冲） and ren （任） meri-dians. The resulting obstruction in the uterus can， in turn， manifest externally and aggravate damage to the body and viscera. Therefore， the pathogenesis of SLE secondary gynecological and obstetric diseases follows a dynamic trajectory of "body bi first， body bi affecting viscera， and then bi of both body and viscera". In treatment， the principle of harmonizing and balancing the healthy qi is emphasized. The main approach is to regulate the viscera， stabilize the body， and nourish the uterus， with the coordination of nourishing the viscera through the body， thereby achieving simultaneous treatment of both body and viscera. This highlights the guiding significance of the "bi of both body and viscera" theory in preventing and treating SLE secondary gynecological and obstetric diseases.

Objective To investigate the role of macrophages in the process of fine particulate matter (PM2.5)exposure induced damage to pulmonary blood-air barrier.Methods Eighteen male BALB/C mice (aged of 10 weeks,weighing 24～27 g)were randomly divided into control group and low-and high-dose PM2.5 exposure groups (receiving 1 .8 and 16.2 mg/kg,respectively),with 6 mice in each group.The control group received tracheal instillations of normal saline on days 1,4,and 7,whereas the exposure groups were administered corresponding dose of PM2.5 exposure at the same time points.In 24 h after last exposure,pathological changes in the lung tissues were observed,and the contents of total protein (TP ),lactate dehydrogenase (LDH ),and alkaline phosphatase (AKP ) in bronchoalveolar lavage fluid (BALF ),and F4/80 protein level in lung tissue were measured to evaluate the blood-air barrier damage and macrophage infiltration within the lung tissues.Additionally,an in vitro model of the blood-air barrier was established using A549 alveolar epithelial cells and EA.hy926 vascular endothelial cells.In combination with a THP-1 macrophage model,the supernatant PM2.5 supernatant,macrophage supernatant,and PM2.5-macrophage supernatant were incubated with the barrier model for 24 h,respectively.Transmembrane electrical resistance (TEER),sodium fluorescein permeability of the barrier model,and LDH release from the barrier cells were measured to ascertain the extent of macrophage-mediated enhancement in barrier damage induced by PM2.5 exposure.Furthermore,the expression of inflammatory cytokines,such as TNF-α,IL-1β,IL-6,and IL-8 in the macrophages after PM2.5 exposure was analyzed with quantitative real-time PCR (qPCR)and enzyme-linked immunosorbent assay (ELISA).Results PM2.5 exposure induced lung tissue damage in mice in a dose-dependent manner,significantly elevated the contents of TP,LDH and AKP in the BALF and caused marked infiltration of macrophages into the lung tissue,especially the high-dose exposure when compared with the mice from the control group (P<0.01 ).In vitro barrier model exposure experiments showed that in comparison with the treatment of 150 and 300 μg/mL PM2.5 and macrophage supernatant,the same doses of PM2.5-macrophage supernatant resulted in notably decreased TEER and significantly enhanced permeability in the barrier model (P<0.01 ),and markedly increased LDH release from epithelial and endothelial barrier cells (P<0.01 ).Additionally,the exposure of 150 and 300μg/mL PM2.5 led to a significant up-regulation of TNF-α,IL-1β,IL-6,and IL-8 in the macrophages (P<0.01 ).Conclusion Macrophages deteriorate PM2.5-induced functional impairment of the pulmonary blood-air barrier.

Visual hallucination(VH)is a common symptom of schizophrenia,the underlying mechanism has not been fully elucidated.It has been found that the dysfunction of dopamine(DA)system,the overactivation of α-amino-3-hydroxy-5-methyl-4-isoxazole-propionate(AMPA)receptor in glutamate system and the dysfunction of γ-aminobutyric acid(GABA)ergic neurons can induce VH in patients with schizophrenia.In addition,abnormalities in brain structural and functional networks and visual networks are also closely related to the occurrence of VH.The purpose of this paper is to review the neurochemistry and nerve injury mechanism of VH in schizophrenic patients to deeply understand the characteristics of VH,and make more accurate judgment in the early diagnosis,condition evaluation and treatment plan of schizophrenic patients.

ObjectiveTo evaluate the clinical efficacy and safety of Tripterygium wilfordii polyglycoside tablets （TWP） in the treatment of rheumatoid arthritis （RA） in the real world. MethodDiagnosis and treatment data of patients with RA in Chinese medicine rheumatology registration research information platform information database （CERTAIN） from January 1，2019 to January， 2024 were collected. According to the inclusion and exclusion criteria， data were screened. The included data were divided into an exposure group and a control group according to the use of TWP or not. Propensity score matching （PSM） was used in both groups to keep the baseline balanced and comparable. The disease activity score （DAS28-ESR） of 28 joints based on the erythrocyte sedimentation rate （ESR）before and after treatment was compared between the two groups， as well as health assessment questionnaire （HAQ），visual analogue scale （VAS），tender joint count （TJC），swollen joint count （SJC）， patient's global assessment （PGA），evaluator's global assessment （EGA），laboratory indexes， clinical curative effect， and adverse reactions. ResultA total of 3 978 patients were included，including 929 in the exposure group and 3 049 in the control group. Before PSM，there were significant differences in demographic information，DAS28-ESR score，PGA，EGA，HAQ，VAS scores，SJC， and TJC between the two groups （P<0.05）. After successful PSM matching，922 patients in the exposure group and 922 patients in the control group were included. There was no significant difference in demographic information and DAS28-ESR between the two groups before treatment，and the differences in other indexes between the two groups decreased to varying degrees. After treatment，the DAS28-ESR，PGA，EGA，HAQ，SJC，TJC，VAS scores， ESR，and IgG immune index of the two groups were significantly lower （P<0.01）. Compared with those in the control group after treatment，the DAS28-ESR，PGA，EGA，HAQ，VAS scores， and ESR in the exposure group after treatment decreased more significantly （P<0.05，P<0.01）. There was no significant difference in TJC in the exposure group after treatment. However， TJC in the exposure group was significantly higher than that in the control group before treatment （P<0.05）. In terms of TJC reduction，the exposure group performed better than the control group. There was no significant difference in SJC and IgG between the exposure group and the control group after treatment. After treatment，the clinical symptoms of poor appetite，insomnia and many dreams，upset，fatigue，and fear of wind and cold in the two groups were improved. Except that the proportion of women in the exposure group was higher than that in the control group （P<0.01），there was no significant difference in the incidence of other adverse reactions between the two groups after treatment. ConclusionTWP to treat RA can effectively reduce DAS28-ESR，PGA，EGA，HAQ，TJC，and VAS scores and improve the general symptoms. Except for the women at childbearing age with fertility requirements that TWP is not applicable，it shows good security.

Abdominal aortic aneurysm (AAA) is a life-threatening disease associated with chronic inflammation in the vascular wall while its specific pathogenesis is not fully understood. Recently, a growing number of studies have indicated that pyroptosis, which is a pro-inflammatory kind of programmed cell death might play a vital role in AAA. In this review, we first summarize the role of pyroptosis in AAA progression by not only providing a literature review on the expression changes of NLRP3 inflammasome components and effector mediators in clinical and experimental AAAs, but also discussing the effects of genetic defects or pharmacological inhibition of NLRP3 inflammasome components on experimental AAAs. Next, we introduce the mechanism of canonical and non-canonical pathway of pyroptosis and its activation and execution process. Finally, we discuss several pyroptosis-related drug targets for treating AAA by inhibiting the assembly of NLRP3 inflammasome and its effector mediators. In conclusion, we believe that pyroptosis might be a new treatment target of AAA.

Student standardized patient refers to that students are trained to become standardized patients, and then they are applied to clinical teaching or examinations. The training of student standardized patients in China started late, but the development is relatively balanced and rapidly in recent years. Although an outline-style standardized teaching model has not yet been formed, the basic training framework of "basic training-case-specific training-training assessment" tends to be consistent, and different universities have certain specific innovations. The review combs the literature on the current training mode of student standardized patients in China, summarizes the innovations in four aspects: training population, training mode, training purpose and application method, then makes the conclusion about the objective problems and subjective difficulties faced by the current training, and proposes corresponding countermeasures and prospects.

Objective:To analyze the influencing factors of catheter-related bloodstream infection (CRBSI) in chronic renal failure (CRF) hemodialysis patients and to construct a risk prediction model.Methods:Using the convenient sampling method, a total of 90 CRF patients who underwent hemodialysis in International Medical Department of Peking Union Medical College Hospital, Chinese Academy of Medical Sciences from May 2018 to May 2021 were selected as the research objects. The gender, age, catheter placement site, catheter type, catheter retention time, catheter care times, tube sealing method, strict hand hygiene, combination with diabetes, hemoglobin, serum albumin, dialysis time, immunosuppressant and other data of the patients were analyzed. Univariate analysis and multivariate Logistic regression were used to analyze the influencing factors of CRBSI in CRF patients and a prediction model was established. Hosmer-Lemeshow (H-L) test and area under the receiver operating characteristic curve ( AUC) were used to verify the fitting effect and discrimination of the model. Results:Among the 90 CRF hemodialysis patients, 16 patients developed CRBSI, with an incidence rate of 17.78% (16/90) . The results of univariate analysis showed that age, catheter placement site, catheter type, catheter retention time, catheter nursing times, strict implementation of hand hygiene, combination with diabetes mellitus, hemoglobin, and serum albumin were the influencing factors of CRBSI in CRF patients ( P<0.05) . Multivariate Logistic regression analysis showed that femoral vein, temporary catheter, catheter retention time greater than 2 weeks, not strictly implementing hand hygiene, complicated with diabetes and serum albumin less than 30 g/L were independent risk factors for CRBSI in CRF hemodialysis patients ( P<0.05) . The H-L test results showed that the model had good goodness of fit (χ 2=7.978, P=0.436) . The receiver operating characteristic curve analysis showed that the AUC of the model was 0.889, the best cut-off value was 0.732, the sensitivity was 81.30% and the specificity was 91.90%. Conclusions:There are many risk factors for CRBSI in RF hemodialysis patients. The establishment of the early warning model is conducive to the early risk assessment of CRBSI occurrence and the formulation of countermeasures to reduce the actual incidence of CRBSI.

Objective:To investigate the effect of IKKε on autophagy during abdominal aortic aneurysm formation in mice.Methods:We stimulated ApoE -/- mice and ApoE -/-IKKε -/- mice with AngⅡ and saline for 28 days. Metaboilic levels and aortic diameter of ApoE -/- mice and ApoE -/-IKKε -/- mice were measured. The arterial fibrosis of mice was detected by Masson staining and HE staining, mitochondrial reactive oxides were detected by fluorescence assay, the expression levels of autophagy factors LC3B and Beclin-1 were detected by immunohistochemistry, and the protein level of LC3B was detected by Western blot. Results:There was no significant difference in metaboilic levels between ApoE -/- mice and ApoE -/- IKKε -/- mice. However, the aortic diameterf ApoE -/-IKKε -/- mice was significantly less than that of ApoE -/- mice. The fibrosis level of ApoE -/-IKKε -/- mice was significantly lower than that of ApoE -/- mice. Furthermore, ROS in ApoE -/-IKKε -/- mice was lower than that in ApoE -/- mice. In addition, immunohistochemical and western blot showed that the expression levels of LC3B and Beclin-1 in ApoE -/-IKKε -/- mice were significantly lower than in ApoE -/- mice. Conclusion:IKKε -/- deficiency can significantly inhibit autophagy, thus reducing the development of abdominal aortic aneurysm in mice.

Decision-making aid for cancer patients is of great significance in the diagnosis and treatment for diseases. Breast cancer is one of the most common malignant tumors in women all over the world, and breast cancer patients have become the main target population for decision-aided research. Application of decision-making assistance for patients in Western countries has developed to a certain extent, while relevant research in China is still at the early stage. There are kinds of intervention forms for patients' decision aids, including traditional brochures and videos, decision aids systems, decision coaching, multidisciplinary breast cancer teams, etc. The tools for decision-making quality evaluation include the patients' awareness for decision-making, participation, decision-making conflict, decision-making satisfaction, decision-making regret, which can provide important guidance for the application of decision-making aid treatment in breast cancer patients in the future.
