Recently， Asian Pacific Association for the Study of the Liver published the recommendations for the diagnosis and management of non-cirrhotic portal fibrosis （NCPF）/idiopathic portal hypertension （IPH）. The guidelines mainly elaborate on the definition， diagnosis， histological features， natural history， and management of NCPF/IPH， in order to strengthen the understanding of NCPF/IPH-related issues and establish a global consensus. This article makes an excerpt of the key statements in the guidelines.

Shengjiangsan is a classic formula for treating warm diseases with wide clinical application and accurate efficacy. There are different opinions on the origin of this formula and lacks key information research on this formula. Therefore， in this study， we conducted systematic research into the historic origin， composition， and other key information of this Shengjiangsan. Results showed that Shengjiangsan has different versions， with "Neixian Fufang"， "Jiawei Jianghuangwan"， "Peizhensan"， and "Taijiwan" being the same formula with different names. Shengjiangsan was first recorded as "Neixian Fufang" in Wanbing Huichun written by GONG Tingxian from the Ming dynasty， inherited and developed by YANG Lishan from Qing dynasty， and has been passed down to modern times. Pills and powder are two main forms of Shengjiangsan， and powder has become more popular nowadays. According to the measurement system of Ming and Qing dynasties， the recommended dosage and usage of Shengjiangsan are as follows. For the pill version of Shengjiangsan， Bombyx Batryticatus of 74.6 g， Curcumae Longae Rhizoma of 9.325 g， Cicadae Periostracum of 9.325 g， and Rhei Radix et Rhizoma of 149.2 g were processed into pills for preparation. Single dosage is Bombyx Batryticatus of 1.15 g， Curcumae Longae Rhizoma of 0.14 g， Cicadae Periostracum of 0.14 g， and Rhei Radix et Rhizoma of 2.3 g， with halved dosage applied for children. For the powder version of Shengjiangsan， the dosage varied in accordance with the severity of the disease. Bombyx Batryticatus of 1.84 g， Curcumae Longae Rhizoma of 0.28 g， Cicadae Periostracum of 0.92 g， and Rhei Radix et Rhizoma of 3.68 g were processed into powder for patients with mild symptoms. Bombyx Batryticatus of 2.48 g， Curcumae Longae Rhizoma of 0.37 g， Cicadae Periostracum of 1.23 g， and Rhei Radix et Rhizoma of 4.91 g were processed into powder for patients with severe symptoms. Bombyx Batryticatus of 3.68 g， Curcumae Longae Rhizoma of 1.84 g， Cicadae Periostracum of 0.55 g， and Rhei Radix et Rhizoma of 7.36 g were processed into powder for patients with critical conditions. In this formula， four herbs were ground to fine powder. For patients with mild symptoms， the whole formula was divided into four dosages， and each dosage weighed 6.71 g. The 200 mL yellow rice wine and 18.65 g honey were added， and the solution was stirred and taken cold till full recovery. For patients with severe symptoms， the whole formula was divided into three dosages， and each weighed 8.95 g. 300 mL yellow rice wine and 27.98 g honey were added， and the solution was stirred and taken cold. For patients with critical conditions， the whole formula was divided into two dosages， and each weighed 13.43 g. 400 mL yellow rice wine and 37.3 g honey were added， and the solution was stirred and taken cold. Shengjiangsan has the effect of ascending lucidity and descending turbidity， dissipating wind， and clearing heat. It is specialized in treating severe heat in exterior， interior， and triple energizers in warm diseases and has a wide modern clinical application. In this study， the historic evolution and key information of Shengjiangsan were reviewed and analyzed， and the key information table of Shengjiangsan was attached， serving as a reference for scholars' research and a theoretical basis for its market transformation.

Objective:To discuss the protective effect of velvet antler peptide(VAP)in the osteoporosis(OP)model rats,and to clarify the possible mechanism.Methods:Sixty 12-week-old SD rats were randomly divided into control group,model group,positive drug group(treated with 1 mg·kg-1·d-1 of alendronate sodium by gavage),low dose of VAP group(treated with 100 mg·kg-1·d-1 VAP),medium dose of VAP group(treated with 200 mg·kg-1·d-1 VAP),and high dose of VAP group(treated with 300 mg·kg-1·d-1 VAP),and there were ten rats in each group.Except for control group,the rats in the other groups were injected with dexamethasone(2 mg·kg-1)to replicate the OP rat model,while the rats in control group were injected with the equivalent volume of saline twice a week for 11 consecutive weeks.Dual-energy X-ray absorptiometry was used to detect the bone mineral density(BMD)of femur tissue of the rats in various groups;enzyme-linked immunosorbent assay(ELISA)method was used to detect the levels of serum calcium(Ca2+),phosphate(P),osteoprotegerin(OPG),alkaline phosphatase(ALP),and osteocalcin(OCN)in serum of the rats in various groups;biochemical method was used to detect the malondialdehyde(MDA)level and superoxide dismutase(SOD)activity in serum of the rats in various groups;HE staining was used to observe the pathomorphology of bone tissue of the rats in various groups;Western blotting method was used to detect the expression levels of silent information regulator 1(SIRT1),catalase(CAT),Runt-related transcription factor 2(RUNX2),and forkhead box protein O1(FOXO1)proteins in bone tissue of the rats in various groups.Results:Compared with control group,the BMD of femoral tissue of the rats in model group was decreased(P<0.05);compared with model group,the BMD of femur tissue of the rats in positive drug group,medium dose of VAP group,and high dose of VAP group were increased(P<0.05 or P<0.01).Compared with control group,the levels of Ca2+,P,OPG,and SOD activities in serum of the rats in model group were decreased(P<0.05),and the levels of ALP,OCN,and MDA were increased(P<0.05);compared with model group,the level of OPG in serum of the rats in low dose of VAP group was significantly increased(P<0.05),the levels of Ca2+,P,OPG,and activities of SOD in serum of the rats in positive drug group,medium dose of VAP group,and high dose of VAP group were significantly increased(P<0.05 or P<0.01),and the levels of ALP,OCN,and MDA in serum of the rats in positive drug group and different doses of VAP groups were decreased(P<0.05 or P<0.01).The HE staining results showed that compared with control group,the rats in model group had fewer bone cells and disordered arrangements in the bone tissue,thinner bone trabeculae with large fractures,and an expanded marrow cavity;compared with model group,the rats in positive drug group,medium dose of VAP group,and high dose of VAP group had thicker bone trabeculae arranged more tightly.The Western blotting results showed that compared with control group,the expression levels of SIRT1,CAT,RUNX2,and FOXO1 proteins in bone tissue of the rats in model group were decreased(P<0.05);compared with model group,the expression levels of SIRT1,CAT,RUNX2,and FOXO1 proteins in bone tissue of the rats in positive drug group,medium dose of VAP group,and high dose of VAP group were significantly increased(P<0.05 or P<0.01).Conclusion:VAP has the protective effect against OP in the rats,and its mechanism may be related to mediating the antioxidant stress action through the SIRT1/FOXO1 signaling pathway.

Objective:To investigate the therapeutic effect of high-flow nasal cannula oxygen therapy (HFNC) and non-invasive positive pressure ventilation (NPPV) on patients with pulmonary edema caused by seawater drowning.Methods:A retrospective analysis method was used. Based on the Utstein database of emergency drowning in the First Hospital of Qinhuangdao, the clinical data of patients with seawater drowning pulmonary edema admitted to the emergency medicine department of the First Hospital of Qinhuangdao from January 1, 2019 to December 31, 2022 were collected. The patients were divided into NPPV group and HFNC group according to different ventilation methods. The general data, endotracheal intubation rate in 7 days, arterial blood gas analysis indexes [arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2), arterial oxygen saturation (SaO 2)] and hemodynamic indexes (systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, blood lactic acid) before and after treatment, length of stay in intensive care unit (ICU), oxygen therapy comfort of the two groups were compared. Results:A total of 54 patients were enrolled, including 21 patients in the NPPV group and 33 patients in the HFNC group. There were no significant differences in gender, age, state of consciousness and other general information between the two groups. Compared with NPPV group, the rate of endotracheal intubation in HFNC group within 7 days was significantly lower [24.2% (8/33) vs. 33.3% (7/21), P < 0.05]. Before treatment, there were no significant differences in arterial blood gas analysis and hemodynamics between the two groups. After treatment, the above indexes in both groups were significantly improved compared with those before treatment, and PaO 2, SaO 2, systolic blood pressure, diastolic blood pressure and mean arterial pressure in HFNC group were significantly higher than those in NPPV group [PaO 2 (mmHg, 1 mmHg≈0.133kPa): 93.56±6.37 vs. 82.14±6.25, SaO 2: 1.02±0.09 vs. 0.95±0.11, systolic blood pressure (mmHg): 117.37±8.43 vs. 110.42±8.38, diastolic blood pressure (mmHg): 79.43±7.61 vs. 72.21±4.32, mean arterial pressure (mmHg): 92.34±6.32 vs. 85.12±5.38], PaCO 2, heart rate and blood lactic acid were significantly lower than those in NPPV group [PaCO 2 (mmHg) : 34.26±5.63 vs. 37.24±6.22, heart rate (times/min): 73.38±7.56 vs. 86.25±5.41, blood lactic acid (mmol/L): 1.38±0.36 vs. 2.25±1.14], and the differences were statistically significant (all P < 0.05). In addition, the length of ICU stay in HFNC group was significantly shorter than that in NPPV group (days: 13.30±2.38 vs. 16.27±4.26), and the comfort rate of oxygen therapy was significantly higher than that in NPPV group [66.7% (22/33) vs. 42.8% (9/21)], with statistical significance (all P < 0.05). Conclusion:HFNC can improve the oxygenation of patients with pulmonary edema caused by seawater drowning, improve hemodynamics, reduce the rate of tracheal intubation, shorten the length of ICU stay, and improve the comfort of oxygen therapy, which has certain clinical application value.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To explore the safety key points of total pancreaticoduodenectomy in the era of vascular resection technology and the important factors affecting rapid postoperative recovery.Methods:The clinical data of 52 patients with pancreatic cancer who underwent total pancreaticoduodenectomy in Beijing Chaoyang Hospital Affiliated to Capital Medical University from November 2014 to September 2022 were retrospectively analyzed, including 34 males and 18 females, aged (62±9). The intraoperative situation, incidence of postoperative complication, postoperative blood glucose control and postoperative survival rate were analyzed.Results:All operations of the 52 patients were successfully completed, including 48 patients underwent total pancreaticoduodenectomy combined with portal vein resection and allograft vascular grafts via artery approach. The portal vein occlusion time was (20±5) min. The incidence of postoperative complications was 28.8% (15/52), including 2 cases of abnormal gastric empty, 2 cases of diarrhea, 2 cases of chylous fistula, 4 cases of abdominal infection, 1 case of gastrointestinal fistula, 3 cases of gastrointestinal bleeding, and 1 case of pulmonary infection. Subcutaneous short-acting insulin injection was used to control blood glucose in the early stage after surgery, short-acting insulin combined with long-acting insulin was used for subcutaneous injection before sleep for diet recovery. All patients did not experience uncontrolled hyperglycemia. The median survival time of 52 patients was 13 months, and the longest follow-up time was 38 months. There were 37 patients died of tumor recurrence, 4 patients died of cardiovascular and cerebrovascular accidents, and 1 patient died of pulmonary infection in the 42 died patients.Conclusions:Total pancreaticoduodenectomy via artery approach can improve the R 0 resection rate in pancreatic cancer patients with vascular invasion, the rate of postoperative complication and mortality has no significant increase. The postoperative blood sugar control is satisfactory and the quality of life is guaranteed.

Lung cancer is the top cause of cancer deaths globally.Advances in immune checkpoint inhibitors(ICIs)have transformed cancer treatment,but their use in lung cancer has led to more side effects.This study examined if past pulmonary tuberculosis(TB)affects ICIs'effectiveness and safety in lung cancer treatment.We reviewed lung cancer patients treated with ICIs at Beijing Chest Hospital from January 2019 to August 2022.We compared outcomes and side effects between patients with and without prior TB.Of 116 patients(40 with TB history,76 without),prior TB didn't reduce treatment effectiveness but did increase severe side effects.Notably,older patients(≥65 years)faced a higher risk of severe side effects.Detailed cases of two patients with severe side effects underscored TB as a risk factor in lung cancer patients receiving ICIs,stressing the need for careful monitoring and personalized care.

Objective To compare the outcomes of transplant kidneys and patient survival between simultaneous pancreas-kidney transplantation(SPKT)recipients and deceased donor kidney transplant(DDKT)recipients in patients with type 2 diabetes mellitus(T2DM)complicated with end-stage renal disease(ESRD),and to analyze the risk factors affecting patient survival post-SPKT.Methods Clinical and prognostic data of patients who underwent kidney transplantation from January 27,2003,to January 1,2021,were retrieved from the United Network for Organ Sharing(UNOS)database.A total of 50 230 cases were selected based on inclusion criteria,with 48 669 cases in DDKT group and 1561 cases in SPKT group.Kaplan-Meier analysis was employed to compare transplant kidney and patient survival between the two groups,and propensity score matching(PSM)was utilized to balance confounding factors between the groups.Cox regression model was used to analyze independent risk factors affecting patient survival post-SPKT.Results Compared with DDKT group,recipients in SPKT group had a younger median age(P<0.001),a higher proportion of males(P<0.001),lower BMI(P<0.001),shorter dialysis and transplant waiting times(P<0.001),a higher percentage of private medical insurance(P<0.001),a lower proportion of previous transplants(P<0.001),a younger age at diabetes diagnosis(P<0.001),and a lower incidence of peripheral vascular disease(P=0.033).Compared with DDKT group,the donors in SPKT group had a younger median age(P<0.001),a higher proportion of males(P<0.001),lower BMI(P<0.001),and a lower prevalence of hypertension and diabetes history(P<0.001).In terms of transplant-related factors,the SPKT group had a shorter donor kidney cold ischemia time(P<0.001),a higher degree of HLA mismatch(P<0.001),and a lower Kidney Donor Profile Index(KDPI)(P<0.001)when compared with DDKT group.The SPKT group had lower serum creatinine levels at discharge(P<0.001),lower rates of postoperative delayed graft function(DGF)and acute rejection(AR)(P<0.001),but longer hospital stays(P<0.001)when compared with DDKT group.Kaplan-Meier survival analysis curves,both original and after propensity score matching(PSM),consistently showed significantly higher transplant kidney and patient survival rates in SPKT group compared with DDKT group(P<0.001).Cox regression model analysis indicated that recipient age,recipient race,donor age,and donor kidney cold ischemia time were independent risk factors influencing patient survival post-SPKT.Conclusions For ESRD patients with T2DM,SPKT offers improved long-term graft and patient survival rates compared with DDKT.Recipient age,recipient ethnicity,donor age,and cold ischemia time for the donor's kidney are independent risk factors affecting post-SPKT patient survival.

Objective To investigate the correlation between the level of N-terminal pro-Brain natriuretic peptide(NT-proBNP)and cardiorespiratory fitness following acute exposure to high altitude.Methods Forty-six subjects were recruited from the Second Affiliated Hospital of Army Medical University in June 2022,including 19 males and 27 females.After completing cardiopulmonary exercise test(CPET),serological detection of myocardial cell-related markers,and multiple metabolites at a plain altitude(300 meters above sea level),all subjects flew to a high-altitude location(3900 meters above sea level).Biomarker testing and CPET were repeated on the second and third days after arrival at high altitude.Changes in serum biomarker and key CPET indicators before and after rapid ascent to high altitude were compared,and the correlation between serum levels of various myocardial cell-related markers and metabolites and high altitude cardiorespiratory fitness was analyzed.Results Compared with the plain altitude,there was a significant decrease in maximal oxygen uptake after rapid ascent to high altitude[(25.41±6.20)ml/(kg.min)vs.(30.17±5.01)ml/(kg.min),P<0.001].Serum levels of NT-proBNP,Epinephrine(E),plasma renin activity(PRA),angiotensin Ⅱ(Ang Ⅱ),angiotensin-converting enzyme 2(ACE2)and leptin(LEP)significantly increased,with all differences being statistically significant(P<0.05)after acute high altitude exposure.In contrast,no statistically significant differences were observed for creatine kinase MB(CK-MB),cardiac troponin I(cTnI),myoglobin(Myo)and norepinephrine(NE)(P>0.05).Correlation analysis showed a significant negative correlation between NT-proBNP at plain altitude(r=-0.768,P<0.001)and at high altitude(r=-0.791,P<0.001)with maximal oxygen uptake at high altitude.Multivariate linear regression analysis indicated that maximal oxygen uptake at plain altitude(t=2.069,P=0.045),NT-proBNP at plain altitude(t=-2.436,P=0.020)and at high altitude(t=-3.578,P=0.001)were independent influencing factors of cardiorespiratory fitness at high altitude.Conclusion Cardiorespiratory fitness significantly decreases after rapid ascent to high altitude,and the baseline NT-proBNP level at plain altitude is closely related to cardiorespiratory fitness at high altitude,making it a potential predictor indicator for high altitude cardiorespiratory fitness.
