Objective:To systematically review qualitative studies on the experiences of musculoskeletal symptoms in breast cancer patients undergoing endocrine therapy, and to gain insights into the initiation, development, and effects of these symptoms, along with their implications for patients, to guide the creation of targeted strategies for symptom management.Methods:The qualitative studies on the experiences of musculoskeletal symptoms in breast cancer patients undergoing endocrine therapy were performed across several databases, which included the Cochrane Library, Joanna Briggs Institute Evidence based Healthcare Center Database, PubMed, Embase, CINAHL, Web of Science, Scopus, CNKI, Wanfang Data, and Chinese Biomedical Literature Database. The retrieval period was from the establishment of the database to April 30, 2024. The studies' quality was evaluated utilizing the iteration of the Joanna Briggs Institute Qualitative Assessment and Review Instrument designed for qualitative research. Data synthesis was carried out using Meta-aggregation techniques.Results:A total of 15 articles were included and 41 results were extracted, which were grouped into 11 new categories and integrated into 3 primary themes: the manifestation of bone and joint symptoms was highly unique and varied, prominently featuring experiences such as migratory joint pain, morning stiffness, and cramps affecting both large and small joints, frequently associated with functional limitations; these symptoms significantly influence patients' everyday activities and mental health, contributing to feelings of anxiety, avoidance behaviors, fear, and a reduction in overall quality of life; to manage the intricate nature of their symptoms, patients employ a variety of coping mechanisms, such as engaging in physical activity, taking dietary supplements, consulting about medications, and seeking support from external sources.Conclusions:During endocrine therapy for breast cancer, patients exhibit diverse characteristics of musculoskeletal symptoms, and the resulting fear of recurrence, avoidance behaviors, and anxiety have a negative impact on their psychological well-being and overall health. Healthcare professionals should take into account individual differences, such as age, menopausal status, type of endocrine therapy, medication adherence, and factors that may exacerbate or alleviate symptoms, in order to effectively predict, assess, and manage bone and joint symptoms during endocrine therapy.

To summarize the clinical experience of Professor WANG Jie in treating palpitation using the method of tonifying the kidneys and invigorating blood. It is believed that kidney yang deficiency and heart vessel stasis are the key pathogenesis of palpitation, and it is advocated to treat palpitation by tonifying the kidney and invigorating the blood. Meanwhile,the methods of draining water, dissolving phlegm, and fortifying the spleen to supplement the blood should be applied. For palpitation with kidney yang deficiency and heart vessel stasis with upward water, the treatment could use self-prescribed Bushen Huoxue Lishui Formula (补肾活血利水方); for palpitation with phlegm obstruction in blood vessel, the treatment could use self-prescribed Bushen Huoxue Huatan Formula (补肾活血化痰方); for palpitation with spleen yang deficiency, the treatment could use self-prescribed Bushen Huoxue Jianpi Formula (补肾活血健脾方).

Objective:To investigate the characteristics of clinical manifestations and parameters of 24 hour multichannel intraluminal impedance and pH monitoring (24 h MII-pH) in patients with low mean nocturnal baseline impedance (MNBI) of proximal esophagus.Methods:From November 4, 2014 to February 18, 2024, 308 patients who underwent 24 h MII-pH at Peking University First Hospital due to typical gastroesophageal reflux disease symptoms and(or) extra-esophageal symptoms were retrospectively enrolled. MNBI at 17 or 15 cm above the lower esophageal sphincter (LES) < 2 292 Ω was defined as low proximal esophageal impedance (LPEI), both MNBI at 17 and 15 cm above the LES ≥ 2 292 Ω was defined as normal proximal esophageal impedance (NPEI). The 24 h MII-pH parameters were compared between patients with LPEI and patients with NPEI, as well as the incidence of extra-esophageal symptoms. And the 24 h MII-pH parameters were compared between patients with and without extra-esophageal symptoms. Independent sample t-test, Mann-Whitney U test and chi-square test were used for statistical analysis. Results:Among the 308 patients, 71 patients with LPEI, 236 patients with NPEI, and 1 patient was excluded due to missing the 24 h MII-pH data; and there were 215 patients with extra-esophageal symptoms and 93 without extra-esophageal symptoms. The proportion of extra-esophageal symptoms in the LPEI patients was higher than that in the NPEI patients(81.7% (58/71) vs. 66.1% (156/236)), the times of postprandial total reflux, postprandial acid reflux detected by impedance, proximal total reflux, and proximal acid reflux in the LPEI patients were more than those in the NPEI patients (22.5 (22.8) vs. 17.0 (19.0), 10.5 (13.3) vs. 7.0 (13.0), 9.0 (12.0) vs. 5.0 (11.0), 5.0 (10.0) vs. 3.0 (7.0)), and the differences were statistically significant( χ2=6.28, Z=-1.99, -2.06, -2.26 and -2.44; all P<0.05). The times of weak acidic reflux at supine position, proximal total reflux, proximal acid reflux, and proximal non-acid reflux of the patients with extra-esophageal symptoms were more than those in patients without extra-esophageal symptoms (2.0(5.0) vs. 1.0(4.0), 6.0(13.0) vs. 4.0(10.0), 4.0(10.0) vs. 3.0(7.0), 2.0(4.0) vs. 1.0(3.0)), the MNBI at 15 cm above the LES in patients with extra-esophageal symptoms was lower than that in patients without extra-esophageal symptoms ((3 222.4±1 018.7) Ω vs. (3 512.3±1 032.1) Ω), and the differences were statistically significant ( Z=-2.32, -2.25, -2.00 and -2.13, t=-2.28; all P<0.05). Conclusions:LPEI patients have higher proportion of extra-esophageal symptoms, more times of proximal and postprandial acidic reflux. The proximal esophageal impedance and proximal reflux parameters should be emphasized in the diagnosis and treatment of patients with extra-esophageal symptoms.

Epilepsy is a chronic neurological disorder that often begins in childhood and can extend over the entire life course; therefore, it is necessary to establish a long-term, systematic life-course management model. Whole life-cycle disease management emphasizes interventions at key points in time and focuses on diagnosis and treatment points at all stages of life and disease processes. Guided by the concept of holism and preventive treatment, this article discussed the application strategies of TCM in the prevention, control, treatment, health and management of epilepsy in children at different stages. In the prevention period, the disease should be prevented first, and early screening should be carried out; in the control period, the disease should be prevented from changing, and the early intervention of Chinese materia medica should be carried out; during the treatment period, the combination of disease and syndrome and dynamic syndrome differentiation by stages were adopted; during the rehabilitation period, the treatment of different diseases with the same treatment should be emphasized to manage the comorbidity and improve the prognosis; in the long-term management period, the prevention and recovery after stroke should be focused on, and the comprehensive management scheme of TCM in the transition period from children to adults should be put forward. This article systematically expounded the role of TCM in improving seizure control rate and prognosis in the whole life-cycle management of childhood epilepsy, and actively explored the construction of the whole process health management system of chronic diseases.

Objective:To observe the efficacy and safety of vitrectomy combined with subretinal injection of alteplase (tPA) and intravitreal injection of Conbercept in the treatment of large area submacular hemorrhage (SMH) secondary to polypoidal choroidal vasculopathy (PCV).Methods:A retrospective clinical study. From January to September 2021, 32 eyes of 32 patients with massive SMH secondary to PCV diagnosed in the Affiliated Eye Hospital of Nanchang University were included in the study. Large SMH was defined as hemorrhage diameter ≥4 optic disc diameter (DD). There were 32 patients (32 eyes), 20 males and 12 females. The mean age was (72.36±8.62) years. All patients had unilateral disease.The duration from onset of symptoms to treatment was (7.21±3.36) days. All patients underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examination. BCVA examination was performed using the international standard visual acuity chart, which was converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. The central macular thickness (CMT) was measured by spectral domain-OCT. The average size of SMH was (6.82±1.53) DD. The logMAR BCVA 1.73±0.44; CMT was (727.96±236.40) μm. All patients were treated with 23G pars plana vitrectomy combined with subretinal injection of tPA and intravitreal injection of Conbercept. At 1, 3, 6 and 12 months after treatment, the same equipment and methods were used for relevant examinations before treatment. The changes of BCVA and CMT, the clearance rate of macular hemorrhage, and the complications during and after surgery were observed. BCVA and CMT before and after treatment were compared by repeated measures analysis of variance.Results:Compared with before treatment, BCVA gradually increased at 1, 3, 6 and 12 months after treatment, and the differences were statistically significant ( F=77.402, P<0.001). There was no significant difference in BCVA between any two groups at different time points after treatment ( P>0.05). Correlation analysis showed that BCVA at 12 months after treatment was negatively correlated with the course of disease ( r=-0.053, P=0.774). One week after treatment, macular hemorrhage was completely cleared in 30 eyes (93.75%, 30/32). The CMT was (458.56±246.21), (356.18±261.46), (345.82±212.38) and (334.64±165.54) μm at 1, 3, 6 and 12 months after treatment, respectively. Compared with before treatment, CMT decreased gradually after treatment, and the difference was statistically significant ( F=112.480, P<0.001). There were statistically significant differences in different follow-up time before and after treatment ( P<0.001). The number of treatments combined with Conbercept during and after surgery was (4.2±1.8) times. At the last follow-up, there was no recurrence of SMH, retinal interlamellar effusion and other complications. Conclusion:Subretinal injection of tPA combined with intravitreal injection of Conbercept is safe and effective in the treatment of large SMH secondary to PCV, and it can significantly improve the visual acuity of patients.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5%were gram-positive and 70.5%were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3%,76.7%and 77.9%,respectively.Overall,94.0%of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8%of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2%in the isolates from children and 95.7%in the isolates from adults.The resistance rate to carbapenems was lower than 13.1%in most Enterobacterales species except for Klebsiella,21.7%-23.1%of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1%to 13.3%.The prevalence of meropenem-resistant strains decreased from 23.5%in 2019 to 18.0%in 2022 in Pseudomonas aeruginosa,and decreased from 79.0%in 2019 to 72.5%in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.
