Metabolic-associated fatty liver disease (MAFLD) and osteoporosis (OP) are two very common metabolic diseases. A growing body of experimental evidence supports a pathophysiological link between MAFLD and OP. MAFLD is often associated with the development of OP. Rutaecarpine (RUT) is one of the main active components of Chinese medicine Euodiae Fructus. Our previous studies have demonstrated that RUT has lipid-lowering, anti-inflammatory and anti-atherosclerotic effects, and can improve the OP of rats. However, whether RUT can improve both fatty liver and OP symptoms of MAFLD mice at the same time remains to be investigated. In this study, we used C57BL/6 mice fed a high-fat diet (HFD) for 4 months to construct a MAFLD model, and gave the mice a low dose (5 mg·kg^-1) and a high dose (15 mg·kg^-1) of RUT by gavage for 4 weeks. The effects of RUT on liver steatosis and bone metabolism were then evaluated at the end of the experiment [this experiment was approved by the Experimental Animal Ethics Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences (approval number: IMB-20190124D₃03)]. The results showed that RUT treatment significantly reduced hepatic steatosis and lipid accumulation, and significantly reduced bone loss and promoted bone formation. In summary, this study shows that RUT has an effect of improving fatty liver and OP in MAFLD mice.

After 50 years of clinical development， endoscopic retrograde cholangiopancreatography （ERCP） has become the preferred method for the clinical diagnosis and treatment of cholangio-pancreatic duct diseases； however， the major postoperative complications of ERCP， such as pancreatitis， hemorrhage， and perforation， are still a difficult issue faced by clinicians， and postoperative perforation is associated with an extremely high risk of death. Therefore， it is very important to explore the risk factors for perforation after ERCP， make a definite diagnosis of perforation in a timely manner， and formulate precise prevention and treatment measures. By reviewing a large number of articles， this article summarizes the influencing factors for perforation after ERCP and related diagnosis and treatment measures.

According to the "Regulations on clinical application management of medical technologies", physicians intending to carry out restricted technologies must undergo standardized training and pass assessments in accordance with the clinical application management standards for the respective technology. As ventricular assist technology is classified as a nationally restricted technology, standardized training is one of the essential conditions for its application. This paper primarily explores the standardized training for the clinical application of ventricular assist technology in Shanghai, in light of its background, clinical application, and current training status. It proposes the training requirements for ventricular assist technology, animal training assessment standards, and clinical practice assessment standards in Shanghai, aiming to promote the standardized development and high-quality advancement of ventricular assist technology in Shanghai.

Background Affected by concentration, composition, and population tolerance of air pollutants, the relationship between air pollutants and population health has regional differences. There is still a research gap in Guiyang. Objective To explore the short-term effects of air pollutant concentrations in low-pollution areas on the outpatient volume of respiratory diseases. Methods Spearman correlation analysis was used to evaluate the correlation between air pollutants, meteorological factors, and respiratory outpatient volume from January 1, 2013 to December 31, 2020 in Guiyang City. A single pollutant distribution lag nonlinear model and a multi-pollutant interaction model were established based on Poisson distribution. A three-dimensional diagram was drawn to display the relationship between air pollutants and respiratory outpatient volume. Quantitative analysis was conducted on the attribution risk and lag effect of air pollutant concentration on outpatient volume of respiratory diseases in Guiyang City. Results The results of the single pollutant model showed that fine particulate matter (PM_2.5), nitrogen dioxide (NO₂), carbon monoxide (CO), and sulfur dioxide (SO₂) elevated the outpatient volume of respiratory diseases. The maximum relative risk (RR) and 95%CI values of PM_2.5, NO₂,CO, and SO₂ appeared on Day 2, 0, 5, and 6, respectively, which were 1.019 (1.015, 1.023), 1.146 (1.122, 1.171), 1.129 (1.116, 1.143), and 1.046(1.040, 1.052), respectively. For every quartile concentration increment of PM_2.5, NO₂, CO, or SO₂, the outpatient volume of respiratory diseases increased by 0.943% (0.111%, 1.782%), 4.050% (3.573%, 4.529%), 0.595% (0.317%, 0.874%), or 0.667% (0.235%, 1.100%), respectively. The maximum RR (95%CI) of O₃ was 1.015 (1.007, 1.023) and appeared on Day 0. The results of multi-pollutant model showed that PM_2.5, NO₂, CO, SO₂, and O₃ all elevated the outpatient volume of respiratory diseases. The maximum RR values of PM_2.5, NO₂, CO, SO₂ and O₃ appeared on Day 14, 0, 5, 7 and 0, respectively, which were 1.027 (1.021, 1.034), 1.213 (1.179, 1.248), 1.059 (1.043, 1.074), 1.016 (1.005, 1.026), and 1.024 (1.015, 1.033), respectively. Compared with the single pollutant model, the RR values of PM_2.5, NO₂, and O₃ on the outpatient volume of respiratory diseases in the multi-pollutant model showed an upward trend, while the RR values of CO and SO₂ in the multi-pollutant model showed a downward trend. Conclusion The impact of low concentrations of PM_2.5, NO₂, CO, and SO₂ on human health cannot be ignored.

Objective To explore the antimicrobial resistance of carbapenem-resistant Klebsiella pneumoniae(CRKP)isolated from blood and the related risk factors for infection in patients.Methods Clinical data of 383 KP-infected patients from whose blood Klebsiella pneumoniae(KP)were isolated during hospitalization period in a hos-pital from January 2018 to December 2021 were retrospectively analyzed.Patients were divided into CRKP group(n=114)and non-CRKP group(n=269)based on antimicrobial resistance.According to the prognosis,114 patients in the CRKP group were subdivided into the death group(n=30)and the survival group(n=84).General informa-tion,underlying diseases,antimicrobial use,and infection outcomes of two groups of patients were compared,and risk factors for infection and death after infection were analyzed.Results The resistance rates of KP to tigecycline and compound sulfamethoxazole showed upward trends,with statistically significant differences(both P=0.008).The CRKP group had higher resistance rates to amikacin,aztreonam,compound sulfamethoxazole,ciprofloxacin,cefepime,cefoperazone/sulbactam,piperacillin/tazobactam,tigecycline,ceftazidime,tobramycin,and levofloxacin,as well as higher in-hospital mortality than the non-CRKP group,with statistically significant differences(all P＜0.05).Acute pancreatitis prior to infection(OR=16.564,P＜0.001),hypoalbuminemia(OR=8.588,P＜0.001),stay in in-tensive care unit prior to infection(OR=2.733,P=0.017),blood transfusion(OR=3.968,P=0.001),broncho-scopy(OR=5.194,P=0.014),surgery within 30 days prior to infection(OR=2.603,P=0.010),and treatment with carbapenems(OR=2.663,P=0.011)were independent risk factors for the development of CRKP blood-stream infection(BSI).Cardiac insufficiency before infection(OR=11.094,P=0.001),combined with pulmonary infection(OR=20.801,P=0.010),septic shock(OR=9.783,P=0.002),disturbance of consciousness(OR=11.648,P=0.001),and receiving glucocorticoid treatment(OR=5.333,P=0.018)were independent risk factors for mortality in patients with CRKP BSI.Conclusion The resistance rate of KP from BSI to tigecycline and com-pound sulfamethoxazole presents upward trend.Underlying diseases,invasive procedures,and carbapenem treat-ment are closely related to CRKP BSI.Cardiac insufficiency,pulmonary infection,septic shock,disturbance of con-sciousness,and glucocorticoid treatment can lead to death of patients with CRKP BSI.

Objective To investigate the effect of brachial plexus block on stress response in patients who underwent shoulder arthroscopic surgery.Methods A total of 150 patients with shoulder arthritis who underwent shoulder arthroscopic surgery in the Shanghai Fifth People's Hospital,Fudan University from December 2021 to December 2022 were selected as the study subjects.All patients were divided into the control group and the observation group by random number table method,with 75 cases in each group.Patients in the control group were given general anesthesia,while patients in the observation group were given brachial plexus block on the basis of the control group.The mean arterial pressure(MAP),heart rate(HR),norepinephrine(NE),cortisol(Cor)before operation(T0),10 minutes after operation(T1),30 minutes after operation(T2),at the end of operation(T3)and 30 minutes after extubation(T4)of the two groups were compared.The transforming growth factor-β1(TGF-β1),tumor necrosis factor-α(TNF-α),C-reactive protein(CRP)before and 3 days after operation of the two groups were compared.The visual analogue scale(VAS)scores at postoperative wakefulness and 6,12 and 24 hours after operation of the two groups were compared.Results Compared with T0,the levels of MAP and HR at T1,T2,T3,and T4 in the observation group and the control group were obviously decreased(P<0.01),the levels of NE and Cor were obviously increased(P<0.01),while the levels of MAP,HR,NE,and Cor at T1,T2,T3,and T4 in the observation group were obviously lower than those in the control group(P<0.01).The levels of TGF-β1,TNF-α,and CRP 3 days after operation in the observation group and the control group were obviously increased compared with those before operation (P<0. 01), and the above indicators after operation in the observation group were obviously lower than those in the control group (P<0. 01). The VAS scores at postoperative wakefulness and 6, 12 and 24 hours after operation in the observation group were obviously lower than those in the control group (P<0. 01). Conclusion Ultrasound-guided brachial plexus block by interscalene approach can ensure the stability of the vital signs of patients with shoulder arthritis during shoulder arthroscopic surgery, alleviate pain, reduce stress, and reduce inflammatory response.

Dental pulp stem cells (DPSC) are pluripotent stem cells with high differentiation potential isolated from dental pulp. Using DPSC for vascular regeneration may be a good option. Hypoxia inducible factor-1α (HIF-1α) is an upstream gene of vascular endothelial growth factor (VEGF), and the small ubiquitin like protease 1 (SENP1) can reverse the small ubiquitin like (SUMO) modification of HIF-1α. Through the regulation of SENP1/HIF-1α, good vascular regeneration characteristics have been demonstrated in many in vitro and in vivo experiments. The SENP1/HIF-1α signaling axis has varying degrees of promoting and inhibiting effects on many solid tumors. Although there is relatively little literature on the role of the SENP1/HIF-1α signaling axis in dental pulp stem cells, it can be determined that SENP1/HIF-1α plays an important role in the angiogenesis of dental pulp stem cells. This article will elucidate the SENP1/HIF-1α signaling pathway and its mechanism of promoting vascular differentiation of DPSC.

Objective To investigate the impacts of cinobufotalin combined with docetaxel+cisplatin chemotherapy on the disease control and the level of vascular endothelial growth factor(VEGF)in serum of patients with non-small cell lung cancer.Methods Totally 70 patients with non-small cell lung cancer admitted to Zhejiang Veteran Hospital from March 2019 to March 2022 were included.They were randomly divided into combination group(cinobufotalin combined with docetaxel+cisplatin,n= 35)and control group(docetaxel+cisplatin chemotherapy alone,n=35).The disease control rates of two groups,serum VEGF level,carcinoembryonic antigen(CEA),cy-tokeratin 19(CK19)and carbohydrate antigen 125(CA125)were measured using ELISA;life quality of patients was evaluated with the KPS score;The adverse events between two groups were compared.Results The disease control rate in the combination group(33/35,94.29％)was higher than that that of control group(25/35,71.43％,)(P＜0.05).After treatment,the level of VEGF in both groups of patients decreased,and the KPS score increased(P＜0.05)especially in the combination group(P＜0.05).After treatment,the level of serum CEA,CA125,and CK19 of control group and combination group were obviously lower than those before treatment(P＜0.05),while those in the combination group were even lower(P＜0.05).The incidence of adverse events in the combination group(5/35,14.29％)was lower than that in the control group(13/35,37.14％)(P＜0.05).Conclusions Cinobufotalin combined with docetaxel+cisplatin chemotherapy as a potential new chemotherapy significantly reduces the level of VEGF and tumor biomarkers in serum factor,improves the life quality of patients.The combined therapy is proved tobe safe.

Screening and evaluating the diseases responding specifically to traditional Chinese medicine （TCM） will help to highlight the advantages of TCM treatment， and the evaluation method should be standardized with consideration to the unique characteristics of the diseases. The incidence of Sjögren's Syndrome （SS） is increasing year by year， while the pathogenesis of this disease remains unclear. Modern therapies for this disease include biological agents and immunosuppressants， which generally have unsatisfactory efficacy. The TCM treatment of SS focuses on the harmony of the physical and mental health. The Rheumatology Branch of the China Association of Chinese Medicine organizes experts in TCM， Western medicine， and evidence-based medicine to form working groups. Delphi method and bibliometric method were used for analysis， and SS was selected as a disease responding specifically to TCM. Furthermore， the evaluation system was established for this disease， and the consensus regarding this disease was reached after seminar discussion. This paper summarized the whole process of the evaluation of the advantages of TCM treatment of SS. First， because TCM atomization is widely used in clinical practice and enriches TCM administration methods， this therapy is included after other non-drug therapies were taken as characteristic therapies. Second， the evaluation indicators of therapeutic effect should be determined with consideration to international acceptance and the current research status. Third， the expression method should be accurate， standardized， and objective， highlight the natural advantages of TCM， and avoid arbitrary extension. This paper provides a reference for clinicians to explore other diseases responding specifically to TCM.

Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.
