Severe acute pancreatitis （SAP） is closely related to dysfunction of the spleen-stomach ascent and descent. Due to the influence of modern lifestyle and dietary factors， Qi deficiency in the spleen and stomach has become the pathological basis of SAP. Its pathogenesis is characterized by dampness， heat， pathogenic factors， stasis， stagnation， obstruction， Fu-organs Qi obstruction， pathogenic excess， and healthy Qi deficiency. At different stages of the disease course of SAP， there is a focus on both pathogenic excess and healthy Qi deficiency. It is specifically manifested as Fu-organs stagnation and heat accumulation， as well as pathogenic excess and healthy Qi deficiency， during the systemic inflammatory response phase， intermingling of blood stasis and pathogenic factors， as well as Qi deficiency and blood stasis， during the infection period， and weakness of the spleen and stomach， as well as healthy Qi deficiency and lingering pathogenic factors， during the residual infection period. Based on the theory that "the spleen and stomach are the acquired foundation"， a staged treatment method centered on the core principle of "strengthening healthy Qi to eliminate pathogenic factors" was developed. The staged treatment method included "clearing the Fu-organs to expel turbidity， replenishing Qi to harmonize the stomach， activating blood circulation to expel pathogenic factors， replenishing Qi to relieve pain， promoting digestion to stimulate appetite， and replenishing Qi to invigorate the spleen". In clinical practice， Hewei Tongxie mixture， Yikang mixture， and Shiwei Jianpi Xiaoshi powder were selected for staged treatment of SAP. This article systematically summarized the theoretical basis of traditional Chinese medicine， Western medicine foundation， modern pharmacological mechanisms， and clinical application experience of the staged treatment of SAP with "strengthening the healthy Qi to eliminate pathogenic factors"， providing new ideas for the treatment of SAP with traditional Chinese medicine.

Objective:To investigate the predictive value of cardiopulmonary exercise test (CPET) indexes for major adverse cardiovascular events (MACE) in patients with coronary heart disease (CHD).Methods:This study was a retrospective cohort study. CHD patients were consecutively enrolled who procedure CPET before discharge from the Department of Cardiology, General Hospital of Northern Theater Command from November 2015 to September 2021 were enrolled. Demographic information, past medical history, CPET indexes and other baseline data were collected and the patients were followed up. Patients were divided into a MACE group and a control group according to the presence or absence of MACE. A multivariate Cox proportional hazard regression model was used to analyze the CPET indexes with predictive value for MACE in CHD patients.Results:A total of 3 800 patients were eligible for the criterion, age (57.2±8.8) years, 2 920 (76.84%) males. During a follow-up of 1 237 (695, 1 596) days, 390 (10.26%) patients were in MACE group, and 3 410 (89.74%) patients were in control group. In adjusted multivariable analysis, higher metabolic equivalent of tasks (MET) at anaerobic threshold (AT) is an independent protective factor for MACE in patients with CHD ( HR=0.75, 95% CI 0.62-0.90, P=0.002), higher VE/VCO 2 is an independent risk factor for MACE in CHD patients ( HR=1.05, 95% CI 1.02-1.07, P=0.001). Conclusion:In CPET, high MET at AT is an independent protective factor for MACE in patients with CHD, and high VE/VCO 2 is an independent risk factor for MACE in CHD patients.

Objective:To investigate the changes in cardiopulmonary exercise testing (CPET) characteristics before and after the outbreak of COVID-19 in patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI).Methods:This is a cross-sectional study that included ACS patients who underwent PCI at the General Hospital of the Northern Theater Command from July 2018 to February 2023. Based on the timeline of the COVID-19 pandemic, patients were divided into two groups: the pre-pandemic group and the during-pandemic group, with January 2020 as the dividing line. Clinical data were collected from both groups, and a comparative analysis was performed on their postoperative CPET outcomes, including peak oxygen uptake (peak VO 2), peak metabolic equivalents (peak MET), and other indicators. Weber′s classification was used to assess cardiac function. In addition, the 7-tiem generalized anxiety disorder scale (GAD-7) and the patient health questionnaire-9 (PHQ-9) were used to assess the patients′ psychological anxiety and depression states, respectively. Multivariate logistic regression was used to analyze the influencing factors of CPET after PCI. Results:A total of 4 310 post-PCI ACS patients were included, with an average age of (58.7±9.1) years, and 3 464 (80.37%) were male. There were 1 698 patients in the pre-pandemic group and 2 612 patients in the during-pandemic group. The main indicator of the CPET, peak VO 2 (15.04±3.93) ml·min -1·kg -1 in the during-pandemic group, was lower than that in the pre-pandemic group (15.52±3.68) ml·min -1·kg -1, and the difference was statistically significant ( P<0.001). Multivariate logistic regression analysis showed that advanced age, female gender, high body mass index, elevated high-sensitivity C-reactive protein, reduced high-density lipoprotein cholesterol, smoking history, history of myocardial infarction, more severe ACS classification, and mild to moderate degree of depression were related to poor cardiopulmonary outcomes ( P<0.05). Conclusion:The COVID-19 pandemic had a negative impact on the cardiopulmonary outcomes of ACS patients after PCI. Reduced physical activity, and increased psychological stress should be given consideration and attention regarding their impact on patients′ cardiopulmonary function.

Objective:To investigate the different types of renal artery involvement in Stanford type B aortic dissection (TBAD) and the comparison of clinical effecacy after thoracic endovascular aortic repair (TEVAR).Methods:This is a retrospective cohort study included 330 patients with TBAD and renal artery involvement treated with TEVAR from June 2002 to September 2021 in General Hospital of Northern Theater Command of the PLA. According to aortic CTA image, unilateral renal artery involvement conditions were divided into 5 types: the true lumen type (renal artery opening completely from the true lumen), false lumen type (renal artery opening completely from the false lumen), double lumen type (renal artery opening from the true and false double lumen), compression type (renal artery opening connected with the true lumen, but the renal artery opening was extremely squeezed by the inner membrane), open type (renal artery opening with intimal tear). There were seven types of bilateral renal artery involvement: true-true type (true lumen-true lumen type), true and false type (true lumen-false lumen type), true-double type (true lumen-double lumen type), true-opening type (true lumen-opening type), false-false type (false lumen-false lumen type), false-compression type (false lumen-compression type), double-double type (double lumen-double lumen type). The primary observation index of this study was the comparison of postoperative renal function and the incidence of clinical adverse events of different types of renal artery involvement. One-way ANOVA test, Kruskal-Wallis H test and paired sample rank sum test were used to compare postoperative renal function between different types of bilateral renal artery involvement. The Chi-square test or Fisher′s exact probability test were used to compare the near and long term adverse events between different types of bilateral renal artery involvement. Kaplan-Meier method was used to compare the all-cause mortality of patients with severe renal functional injury and non-severe renal functional injury before surgery. Results:The average age of the patients included in this study was (53±11) years, including 276 males (83.6%) and 54 females (16.4%). There were statistical difference in the level of serum creatinine (preoperative: H=18.686, P=0.005, postoperative: H=18.101, P=0.006) and cystatin C (preoperative: H=17.566, P=0.007, postoperative: H=10.433, P=0.016), pre-and post-operative, between the seven groups of TBAD patients with different renal artery involvement types ( P<0.05), and the false-false type group shown the worst kidney function. However, no statistically significant differences were shown when comparing their pre- and post-operative change values ( P>0.05). The 30-day follow-up result showed that there were statistically significant differences in the incidence of postoperative acute kidney injury ( χ2=15.623, P=0.007), aorta-related adverse events ( χ2=15.523, P=0.010), and intraoperative endoleak ( χ2=17.935, P=0.004) among the seven groups, and the false-false group was the highest (2/9, 5/9 and 5/9, respectively). In terms of long-term follow-up results, there were statistically significant differences in all-cause death ( χ2=14.772, P=0.011) and non-aortic death ( χ2=15.589, P=0.008) among the seven groups. Kaplan-Meier survival analysis showed that patients with worse pre-operative renal function showed higher long-term all cause death (17.7% vs. 4.8%, P=0.009). Conclusions:For TBAD patients with renal artery involvement, there were differences in renal function among different types, and TEVAR showed no significant effect on renal function in TBAD patients. The long-term all cause death was higher in patients with worse renal function pre-operative.

With the rapid development of modern biomedicine, subjective factors such as human emotion and disease experience are diluted. Accurate data, programmed diagnosis and treatment process and other objective factors cut off the effective communication between doctors and patients, aggravating the already tense doctor-patient relationship and intensifying various conflicts in the clinic. In order to improve clinical humanistic care, medical and nursing workers have launched reflections and explorations. Narrative medicine is a new form of medical humanistic practice, while parallel chart, as an important way of its practice, records patients’ subjective experiences and painful feelings. It is of great theoretical significance and clinical value to sinicize narrative medicine and construct and promote parallel chart in Traditional Chinese Medicine (TCM) by studying the research progress of parallel chart in China and its application in TCM.

Objective To evaluate the safety and efficacy of transcatheter arterial embolization (TAE) in the management of refractory hematuria of prostatic origin (RHPO). Methods This retrospective study from 6 hospitals in china consisted of 31 patients (mean age 75.0±7.5 years, range 58 to 84 years) who underent transcatheter arterial embolization (TAE) for RHPO between February 2011 and January 2017. Patients with RHPO who had complete imaging and clinical data were enrolled. Patients with incomplete clinical data, inability to assess hemostasis, and contraindications to TAE were excluded. The cause of RHPO was benign prostatic hyperplasia (BPH) in nine patients, prostate cancer in twelve, transurethral resection of prostate in four, open prostatectomy in two and prostatic sarcoma in four.
