Bupivacaine is a long-acting local anesthetic widely used clinically,but its 6-8 hours duration is insufficient for postoperative analgesia.Designing drug dosage forms to prolong the action time of local anesthetics is the research content of local anesthetics.In 2011,the FDA approved a bupivacaine liposome preparation based on DepoFoam TM technology:Exparel,which can be used for more than 72 hours.This article reviewed the clinical safety research of Exparel and the research progress of its application in clinical postoperative analgesia.

The blood-brain barrier (BBB) impairment plays a crucial role in the pathological processes of aging-accompanied neurological diseases (AAND). Meanwhile, circadian rhythms disruption and gut microbiota dysbiosis are associated with increased morbidity of neurological diseases in the accelerated aging population. Importantly, circadian rhythms disruption and gut microbiota dysbiosis are also known to induce the generation of toxic metabolites and pro-inflammatory cytokines, resulting in disruption of BBB integrity. Collectively, this provides a new perspective for exploring the relationship among circadian rhythms, gut microbes, and the BBB in aging-accompanied neurological diseases. In this review, we focus on recent advances in the interplay between circadian rhythm disturbances and gut microbiota dysbiosis, and their potential roles in the BBB disruption that occurs in AAND. Based on existing literature, we discuss and propose potential mechanisms underlying BBB damage induced by dysregulated circadian rhythms and gut microbiota, which would serve as the basis for developing potential interventions to protect the BBB in the aging population through targeting the BBB by exploiting its links with gut microbiota and circadian rhythms for treating AAND.

In recent years， coronary microvascular disease （CMVD）， a main type of ischemic heart disease with high incidence and low diagnosis rate， has become a new research hotspot and received much clinical attention. The etiology of CMVD is complex and the symptoms are various. Traditional Chinese and Western medicine have different opinions on its pathogenesis and treatment plan. Western medicine believes that CMVD is related to structural abnormalities （such as microvascular remodeling， vascular invasion， lumen obstruction， sparse vascular vessel and perivascular fibrosis） and functional abnormalities （such as endothelial dysfunction， smooth muscle cell dysfunction， microvascular constriction， microvascular spasm， inflammation and autonomic nervous dysfunction） of coronary microvascular vessels as well as the extravascular factors （such as heart rate and blood pressure）. In clinics， conventional western medicines are usually used for empirical treatment， but with undesirable effects. Traditional Chinese medicine （TCM） believes that CMVD belongs to the category of "chest impediment"， "heart pain" and "collateral disease"， and the common syndromes include Qi deficiency and blood stasis， Qi stagnation and blood stasis， Qi and Yin deficiency， congealing cold in heart vessel， heart and spleen deficiency， blood stasis obstructing collaterals， combined phlegm and blood stasis， and liver and kidney deficiency， with a variety of treatment methods. Specifically， Chinese patent medicines， self-designed prescriptions， modified classical prescriptions and TCM characteristic therapies have achieved certain effects. This review discussed the risk factors， pathological mechanism， TCM etiology and pathogenesis and traditional Chinese and Western medicine treatment of CMVD， to provide reference for the study and treatment of CMVD.

Immunotherapy combined with effective therapeutics such as chemotherapy and photodynamic therapy have been shown to be a successful strategy to activate anti-tumor immune responses for improved anticancer treatment. However, developing multifunctional biodegradable, biocompatible, low-toxic but highly efficient, and clinically available transformed nano-immunostimulants remains a challenge and is in great demand. Herein, we report and design of a novel carrier-free photo-chemotherapeutic nano-prodrug COS-BA/Ce6 NPs by combining three multifunctional components-a self-assembled natural small molecule betulinic acid (BA), a water-soluble chitosan oligosaccharide (COS), and a low toxic photosensitizer chlorin e6 (Ce6)-to augment the antitumor efficacy of the immune adjuvant anti-PD-L1-mediated cancer immunotherapy. We show that the designed nanodrugs harbored a smart and distinctive "dormancy" characteristic in chemotherapeutic effect with desired lower cytotoxicity, and multiple favorable therapeutic features including improved ¹O₂ generation induced by the reduced energy gap of Ce6, pH-responsiveness, good biodegradability, and biocompatibility, ensuring a highly efficient, synergistic photochemotherapy. Moreover, when combined with anti-PD-L1 therapy, both nano-coassembly based chemotherapy and chemotherapy/photodynamic therapy (PDT) could effectively activate antitumor immunity when treating primary or distant tumors, opening up potentially attractive possibilities for clinical immunotherapy.

With the aging of Chinese society and the deepening of the reform of the medical and health system， pharmaceutical professionals are committed to providing patient-centered， efficient and scientific pharmaceutical care. Continuous pharmaceutical care has become the focus of scholars in this field. In this paper， the concept， importance， dimensions and evaluation indicators of continuous pharmaceutical care， as well as the development status at home and abroad， are reviewed by literature research， and suggestions for development are put forward. The continuous pharmaceutical care has been relatively mature in some developed countries. But in China， due to its late development， it is urgent to explore and develop evaluation indicators suitable for China’s medical and health service system. The continuous pharmaceutical care in China is mainly based on the coordination between comprehensive medical institutions and primary medical institutions within the medical consortium， achieves orderly two-way referral between medical institutions according to the individual situation of patients， and provides individualized drug treatment management for patients during disease prevention， treatment and after treatment.It is suggested to homogenize the pharmaceutical care of medical institutions at different levels， promote the cooperation among the government， medical insurance， superior medical institutions， etc.， so as to improve the pharmaceutical care of primary medical institutions and accelerate the construction of a continuous pharmaceutical care system.

Objective:To evaluate the efficacy and safety of azacitidine combined with HAG regimen in the treatment of newly diagnosed elderly acute myeloid leukemia (AML) patients ineligible for intensive chemotherapy.Methods:Eighteen newly diagnosed elderly AML patients ineligible for intensive chemotherapy from July 2019 to September 2021 in the Second People's Hospital of Shenzhen were prospectively enrolled in this study. They were non-randomly divided into azacitidine combined with HAG regimen (AZA-HAG) group (9 cases) and decitabine combined with HAG regimen (DEC-HAG) group (9 cases). The primary endpoint of the study was overall response [complete remission (CR)+partial remission], and the secondary endpoints included CR + complete remission with incomplete count recovery (CRi), overall survival (OS) and drug safety. Kaplan-Meier method was used to analyze the OS.Results:The median age of 18 patients was 67 years old (60-77 years old) , and 8 of them were in high-risk group. After one course of treatment, the overall response and CR+CRi were observed in 7 of 9 patients in AZA-HAG group, and they were observed in 8 of 9 patients in DEC-HAG group, and there was no significant difference between the two groups (both P = 1.000). The median duration of CR+CRi was 7 months in both groups, and the median OS time was 12 months in both groups; there was no significant difference in OS between the two groups ( χ2 = 0.02, P = 0.895). In AZA-HAG group, 1 patient with TP53 mutation and 1 patient with ASXL1+RUNX1 mutation acquired CR, and 1 patient with NPM1 wild-type combined with FLT3-ITD and ASXL1 mutation did not respond. There was no significant difference in the incidence of grade 3-4 hematological adverse reactions between the two groups (all P < 0.05). Conclusions:Azacitidine combined with low-dose HAG regimen in the treatment of newly diagnosed elderly AML patients ineligible for intensive chemotherapy has satisfactory efficacy and long-term survival, and the adverse reactions can be tolerated.

Objective:To explore the role of creative mind mapping combined with problem-based learning (PBL) in the teaching of standardized residency training of oncologists.Methods:A total of 37 doctors who were trained in the Department of Oncology of Linyi People's Hospital Affiliated to Shandong University from July 2018 to June 2019 were included in the control group, receiving traditional clinical teaching; 39 doctors who were trained from July 2019 to June 2020 were included in the observation group, having creative mind mapping combined with PBL teaching. The two groups were compared with each other in terms of the examination scores (theoretical and practical operation), each dimensional scores and the total score of the Chinese version of the Critical Thinking Disposition Inventory (CTDI-CV) before and after teaching, clinical quality and teaching satisfaction. SPSS 22.0 was used for t test, chi-square test and Z test. Results:There was no statistically significant difference in the scores of theoretical knowledge and operational skills between the two groups before the regular training. After the training, the scores of theoretical knowledge and operational skills of the observation group were both higher than those of the control group [(93.42±4.21) vs. (86.58±5.32), (92.81±4.39) vs. (87.96±5.89), ( P<0.05)]. There was no significant difference between the scores of all dimensions of the CTDI-CV and the total scores of the two groups before the training ( P>0.05). After the training, the scores of the two groups were both improved, and the improvement of the observation group was more significant ( P<0.05). After the training, the scores of the doctors in the observation group on expression and communication ability, humanistic care and literacy, inductive analysis ability, clinical work adaptability, contingency handling ability, hands-on ability, and autonomous learning ability were significantly higher than those of doctors in the control group ( P<0.05). After the training, the total satisfaction of the doctors in the observation group was higher than that in the control group [97.44% (38/39) vs. 81.08% (30/37)], and the difference was statistically significant ( P<0.05). Conclusion:The application of creative mind mapping combined with PBL in the teaching of standardized residency training of oncologists can significantly improve the learning effect of the training doctors, improve their critical thinking ability and clinical comprehensive ability, and can also improve their total satisfaction with teaching.

Lateral epicondylitis is a common clinical disease with characteristics of lateral elbow pain, insidious onset and easy recurrence, which can cause forearm pain and decreased wrist strength, seriously affecting patients′ daily life and work. Although there are various treatment methods for lateral epicondylitis with different effects, standard treatments are still lacking nowadays. Platelet-rich plasma (PRP) has good effects on bone and tendon repair, and is now widely used in the treatment of lateral epicondylitis. However, there is a lack of a unified understanding of the technology and specifications of PRP in the treatment of lateral epicondylitis. Therefore, the Sports Medicine Branch of the Chinese Medical Association and Physical Medicine and Rehabilitation Branch of the Chinese Medical Association organized experts in the fields of sports medicine and rehabilitation medicine in China to formulate the "clinical expert consensus on platelet-rich plasma treatment for lateral epicondylitis (2022 version)", and proposed suggestions based on evidence-based medicine mainly from the concept, epidemiology and pathophysiology of lateral epicondylitis, symptoms, signs and imaging manifestations of lateral epicondylitis, PRP concept and application component requirements, quality control of PRP preparation technology, indications and contraindications of PRP in the treatment of lateral epicondylitis, PRP injection in the treatment of lateral epicondylitis, application of PRP in the operation of lateral epicondylitis, related problems after PRP treatment of lateral epicondylitis, evaluation of the results after PRP treatment of lateral epicondylitis, and health and economic evaluation of PRP treatment of lateral epicondylitis, so as to provide guidance for clinical diagnosis and treatment.

Shexiang Baoxin pills （SBP） are prescribed based on Suhexiang Pills derived from the Formulary of the Bureau of Taiping People's Welfare Pharmacy （《太平惠民和剂局方》） in the Song Dynasty. As the classic Chinese patent medicine in warming and dredging with aromatics， SBP have been widely used in clinical treatment for 30 years by virtue of their unique efficacy in coronary atherosclerotic heart disease （CHD）. Angiogenesis is a biological process in which the body activates angiogenesis-related factors in the body to act on endothelial cells under local vascular injury， tumor growth， local inflammation， and other stimuli to promote the proliferation， migration， and infiltration of endothelial cells， and form new sprouting or non-sprouting blood vessels. As a new strategy for ischemic diseases such as CHD， therapeutic angiogenesis is of great significance in the prevention and treatment of CHD in promoting angiogenesis of ischemic myocardium and establishing effective collateral circulation. However， for the atherosclerotic plaque and tumor， angiogenesis promotion is a risk factor for accelerating the disease progression. Therefore， safe and effective regulation of ischemic myocardial angiogenesis has become the focus of the current prevention and treatment of CHD. Studies in recent years have shown that SBP can intervene in angiogenesis with multiple pathways and targets， which can exert therapeutic angiogenesis effect on CHD and also inhibit atherosclerotic plaque and tumor angiogenesis to varying degrees. This study reviewed the experimental and clinical trials on the regulatory effect of SBPs on angiogenesis in CHD to provide references for the research on Chinese medicine intervention in angiogenesis of CHD.

Objective:To investigate the efficacy and safety of hemodiafiltration (HDF) in treating CAR-T related grade 3-4 cytokine release syndrome after ineffective treatment with IL-6 receptor inhibitors.Methods:Between July 2015 and July 2021, retrospective analysis of hemodiafiltration for the treatment of 3 patients, including 2 cases of acute B-lymphoblastic leukemia and 1 case of diffuse large B-cell lymphoma, with grade 3-4 CRS after CAR-T cell therapy and ineffective treatment with IL-6 receptor inhibitor was carried out.Results:The patient's clinical symptoms, including body temperature, blood pressure, and blood oxygen, were relieved within 12 hours of all treatments, and the cytokines (IL-6, IL-10, TNF-α, INF-γ) and C-reactive protein (CRP) levels decreased significantly. No adverse side effects were observed during the follow-up period of 3 months.Conclusion:HDF can be a safe and feasible method to treat CAR-T related grade 3- 4 CRS after ineffective treatment with IL-6 receptor inhibitors.
