OBJECTIVETo investigate whether emodin exerts protective effects on mouse with allergic asthma.

METHODSA mouse model of allergic airway inflflammation was employed. The C57BL/6 mice sensitized and challenged with ovalbumin (OVA) were intraperitoneally administered 10 or 20 mg/kg emodin for 3 days during OVA challenge. Animals were sacrificed 48 h after the last challenge. Inflammatory cell count in the bronchoalveolar lavage fluid (BALF) was measured. The levels of interleukin (IL)-4, IL-5, IL-13 and eotaxin in BALF and level of immunoglobulin E (IgE) in serum were measured with enzyme-linked immuno sorbent assay kits. The mRNA expressions of IL-4, IL-5, heme oxygenase (HO)-1 and matrix metalloproteinase-9 (MMP-9) were determined by real-time quantitative polymerase chain reaction.

RESULTSEmodin induced significant suppression of the number of OVA-induced total inflammatory cells in BALF. Treatment with emodin led to significant decreases in the levels of IL-4, IL-5, IL-13 and eotaxin in BALF and total IgE level in serum. Histological examination of lung tissue revealed marked attenuation of allergen-induced lung eosinophilic inflammation. Additionally, emodin suppressed IL-4, IL-5 and MMP-9 mRNA expressions and induced HO-1 mRNA expression.

CONCLUSIONEmodin exhibits anti-inflammatory activity in the airway inflammation mouse model, supporting its therapeutic potential for the treatment of allergic bronchial asthma.

OBJECTIVETo investigate the relationship between the clinical character and therapeutic strategy and prognosis in severe acute pancreatitis.

METHODSFrom January 2001 to December 2005, 783 patients with SAP were treated. Therapeutic strategy was selected based on the preliminary scheme for diagnosis and treatment of severe acute pancreatitis by pancreatic surgery society of CMA. All the patients were divided into biliary group and non-biliary group, while 375 patients in biliary group, with 182 patients treated operatively and 193 patients treated nonoperatively; and 408 patients in non-biliary group, with 147 patients treated operatively and 261 patients treated nonoperatively.

RESULTSThere were 698 survivals, the overall survival rate was 89.1%. 357 survivals in the biliary SAP group, the survival rate was 95.0%, in which 171 survivals from operation treated cases, with the survival rate of 94.0%, and 186 survivals from non-operation treated cases, with the survival rate of 96.4%; 341 survivals in the non-biliary SAP group, the survival rate was 84.0%, in which 110 survivals from operation treated cases, with the survival rate of 74.8%, and 231 survivals from non-operation treated cases, with the survival rate of 88.5%. 48.3% patients of the survival group had organ dysfunction, and 18.3% patients had multiple organ dysfunctions, while 100% patients of the death group had organ dysfunction, and 97.6% patients had multiple organ dysfunction. Respiratory dysfunction was found to be the most common cause totally followed by nerve system dysfunction and shock, with the rates of 26.3%, 11.7% and 10.3%, respectively. Respiratory dysfunction, renal dysfunction and cardiac dysfunction are most commonly in death group, with the rate of 94.1%, 60.0% and 60.0%, respectively. The rate of fungi infection in the survival group and death group were 8.9% and 37.6%. The rates of alimentary tract fistula in the survival and death group were 0.9% and 14.1%, respectively.

CONCLUSIONSThe therapy aiming at the cause for biliary SAP and the operation aiming at infected pancreatic necrosis is helpful to improve curative rate; MODS is the main cause of death in severe acute pancreatitis. Respiratory dysfunction, renal dysfunction and cardiac dysfunction are high risk factors.

BACKGROUNDAcute gout is an intensely painful, inflammatory arthritis. Although the non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for this condition, the efficacy is based on only a few studies, particularly in China. We tried to assess the safety and efficacy of etoricoxib in the treatment of acute gouty arthritis in China.

METHODSA randomized, double-blind, active comparator study was conducted at 10 sites in China. Patients (n = 178; ≥ 18 years of age) with acute gouty attack (< 48 hours) were treated for 5 days with etoricoxib (120 mg/d; n = 89) or indometacin (75 mg twice daily; n = 89). The primary efficacy end point was self-assessed pain in the affected joint (0-4 point Likert scale) from days 2 - 5. Secondary end points included investigator assessments of tenderness and swelling, patient/ investigator global assessments of response to therapy, and patients discontinuing treatment. Safety was assessed by adverse events (AEs).

RESULTSEtoricoxib and indometacin had comparable primary and secondary end points. Mean change difference from baseline from days 2 - 5 was 0.03 (95% confidence interval (CI) -0.19 to 0.25; P = 0.6364), which fell within the prespecified comparative bounds of -0.5 to 0.5. No severe AEs were associated with etoricoxib use. Non-severe AEs were mainly digestive and general, and most (73.7%) were mild, although they caused withdrawal of two subjects in the etoricoxib group, due to bilateral renal calculi and uronephrosis of the left kidney (unrelated to etoricoxib) and fever and chills (potentially etoricoxib-related). Overall, AEs were similar, although the absolute number of AEs in the etoricoxib group (n = 31) was less than the indometacin group (n = 34).

CONCLUSIONSEtoricoxib (120 mg once daily) is effective in treating acute gout, is generally safe and well-tolerated, and is comparable in efficacy to indometacin (75 mg twice daily).

Objective: To explore the safety and efficacy of a novel lead locking device (LLD) in the procedure of cardiac lead extraction for heart rhythm implants. Methods: A total of 6 patients using LLD for cardiac lead extraction in our hospital were retrospectively reviewed. Clinical parameters, the reason of cardiac lead extraction, lead locking stylet condition, outcome of lead extraction and operative complications were summarized. Results: There were 6 patients including 1 female with the median age at 62.5 years. LLD was used and 13 cardiac leads were extracted including 1 scrap electrode wire and 12 functional electrode wire. Among those, LLD was successfully inserted and locked on the top of 11/13 (85%) leads for whole procedure and 2 (15%) leads were not locked for whole procedure; 12 (92 %) leads were completely removed and 1 (8%) lead was partially removed. No severe complications occurred. Conclusion: The novel LLD may safely and effectively extract electrode lead which is beneficial for complete cardiac lead extraction.

Objectives:To analyze the clinical characteristics, etiological distribution of inpatients with syncope in our center. Methods:Patients with syncope were consecutively enrolled from September 2014 to April 2017 in Center of Arrhythmia of Fuwai Hospital. Demographics, medical history, physical examination results and laboratory tests were collected according to screen algorism to investigate the possible etiologies of syncope. Risk stratification was performed based on guidelines for the diagnosis and management of syncope (version 2009,ESC)and Chinese expert consensus on the diagnosis and treatment of syncope (version 2014). Results:After collecting medical history, physical examination and performing laboratory tests, three hundred patients who experienced the latest syncope within 180 days before admission was identified from 5 191 patients, the average age was (57.7 ± 15.4) years, 177 (59.0%) were male, 235 (78.3%) experienced syncope within 30 days before admission, 9.7% patients had recurrent episodes, 80.7% were defined as high risk syncope patients, 144(48.0%)patients suffered structural heart disease. Cardiac syncope was the most common etiology (214 cases,71.3%), followed by reflex syncope(44 cases,14.7%) and orthostatic hypotension (8 cases,2.7%), while etiology was not identified in the rest 34 patients (11.3%). Among all the etiologies of syncope, brandy arrhythmia was the most common reason for syncope (37.3% [112 cases]). During onset of syncope prior to hospitalization, five patients were diagnosed with severe intracranial hematoma or cerebral hemorrhage, six cardiopulmonary resuscitations were performed, and eleven patients received external direct current cardioversion. Conclusions:Etiology could be defined in most of the syncope patients admitted to our center, the prevalence of high-risk syncope and syncope due to brady arrhythmias is high in this patient cohort, treatments of the syncope patients could be improved by etiological and timely prognosis.

The paper introduces the clinical experience of GAO Hong in treatment of tic disorder. GAO Hong believes that tic disorder results from the primary qi deficiency and mind disturbance. Acupuncture for cultivating the primary and regulating the mind is proposed specially for tic disorder. This acupuncture technique focuses on harmonizing and regulating governor vessel and conception vessel. In clinical practice, the conception vessel acupoints on the abdomen and the governor vessel acupoints on the head are selected particularly, e.g. Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6) and Guanyuan (CV 4) on the abdomen; Baihui (GV 20), Shenting (GV 24), Benshen (GB 13) and Yintang (GV 24⁺) on the head. The needling sequence and the insertion depth are emphasized, which affect the curative effect and GV 20 is generally punctured first. Besides, considering to the type of disorder and the affected site, tic disorder is treated in view of both syndrome/pattern differentiation and symptom differentiation.

Chronic psychological stress can promote vascular diseases, such as hypertension and atherosclerosis. This study aims to explore the effects and mechanism of chronic psychological stress on aortic medial calcification (AMC). Rat arterial calcification model was established by nicotine gavage in combination with vitamin D₃ (VitD₃) intramuscular injection, and rat model of chronic psychological stress was induced by humid environment. Aortic calcification in rats was evaluated by using Alizarin red staining, aortic calcium content detection, and alkaline phosphatase (ALP) activity assay. The expression levels of the related proteins, including vascular smooth muscle cells (VSMCs) contractile phenotype marker SM22α, osteoblast-like phenotype marker RUNX2, and endoplasmic reticulum stress (ERS) markers (GRP78 and CHOP), were determined by Western blot. The results showed that chronic psychological stress alone induced AMC in rats, further aggravated AMC induced by nicotine in combination with VitD₃, promoted the osteoblast-like phenotype transformation of VSMCs and aortic ERS activation, and significantly increased the plasma cortisol levels. The 11β-hydroxylase inhibitor metyrapone effectively reduced chronic psychological stress-induced plasma cortisol levels and ameliorated AMC and aortic ERS in chronic psychological stress model rats. Conversely, the glucocorticoid receptor agonist dexamethasone induced AMC, promoted AMC induced by nicotine combined with VitD₃, and further activated aortic ERS. The above effects of dexamethasone could be inhibited by ERS inhibitor 4-phenylbutyrate. These results suggest that chronic psychological stress can lead to the occurrence and development of AMC by promoting glucocorticoid synthesis, which may provide new strategies and targets for the prevention and control of AMC.

Applying Chinese medicine (CM) is an important strategy for malignant tumor treatment in China. One of the significant characteristics of CM is to treat diseases based on syndrome differentiation. For Western medicine, it is of important clinical significance to formulate guidelines for the diagnosis and treatment of cancer patients based on the characteristics of disease differentiation. In Chinese clinical practice, the combination of disease differentiation and syndrome differentiation is an important feature for cancer treatment in the past. Currently, molecular profiling and genomic analysis-based precision medicine optimizes the anticancer drug design and holds the greatest success in treating cancer patients. Therefore, we want to know which populations of cancer patients can benefit more from CM treatment if the theory of precision medicine is applied to CM clinical practice. So, we developed a novel diagnostic and therapeutic strategy "disease-syndrome differentiation-genomic profiling-prescriptions" for cancer patients by CM syndrome differentiation and precision medicine. As a result, this strategy has greatly enhanced the anti-tumor efficacy of CM and improved clinical outcomes for cancer patients with some gene mutations. Our idea will hopefully establish a novel approach for the inheritance and innovation of CM.

Objective: To analyze the clinical characteristics of children with multisystem inflammatory syndrome (MIS-C) associated with SARS-CoV-2 in China, and to improve the understanding of MIS-C among pediatricians. Methods: Case series study.Collect the clinical characteristics, auxiliary examinations, treatment decisions, and prognosis of 64 patients with MIS-C from 9 hospitals in China from December 2022 to June 2023. Results: Among the 64 MIS-C patients, 36 were boys and 28 were girls, with an onset age being 2.8 (0.3, 14.0) years. All patients suffered from fever, elevated inflammatory indicators, and multiple system involvement. Forty-three patients (67%) were involved in more than 3 systems simultaneously, including skin mucosa 60 cases (94%), blood system 52 cases (89%), circulatory system 54 cases (84%), digestive system 48 cases (75%), and nervous system 24 cases (37%). Common mucocutaneous lesions included rash 54 cases (84%) and conjunctival congestion and (or) lip flushing 45 cases (70%). Hematological abnormalities consisted of coagulation dysfunction 48 cases (75%), thrombocytopenia 9 cases (14%), and lymphopenia 8 cases (13%). Cardiovascular lesions mainly affected cardiac function, of which 11 patients (17%) were accompanied by hypotension or shock, and 7 patients (12%) had coronary artery dilatation.Thirty-six patients (56%) had gastrointestinal symptoms, 23 patients (36%) had neurological symptoms. Forty-five patients (70%) received the initial treatment of intravenous immunoglobulin in combination with glucocorticoids, 5 patients (8%) received the methylprednisolone pulse therapy and 2 patients (3%) treated with biological agents, 7 patients with coronary artery dilation all returned to normal within 6 months. Conclusions: MIS-C patients are mainly characterized by fever, high inflammatory response, and multiple organ damage. The preferred initial treatment is intravenous immunoglobulin combined with glucocorticoids. All patients have a good prognosis.
