Ultrasound-guided peripheral nerve block is widely used in perioperative pain management of hip fracture patients,which not only provides better analgesia,but also reduces the use of opioids,while tradi-tional techniques such as femoral nerve block and iliofascial space block often result in motor block,which is not conducive to the early rehabilitation of patients.The newly proposed pericapsular nerve block and iliopsoas plane block of the hip can preserve motor function while providing satisfactory analgesia,further in-depth re-search has found that it has great significance in the diagnosis and treatment process of patients with hip frac-tures.This article reviews the innervation of the hip joint,the methods of operation and clinical application of ultrasound-guided pericapsular nerve block and iliopsoas plane block of the hip joint,in order to provide refer-ence for clinical practice.

Objective To analyze the main epidemiological characteristics of fungal infection in this hospital in the past 7 years,and to provide reference for clinical treatment and prevention and control strategies of fun-gal infection.Methods The fungal data and clinical data of related patients isolated from clinical samples in Peking Union Medical College Hospital from early January 2018 to the end of May 2024 were selected,and the main epidemiological characteristics of fungal infection in this hospital were identified and described through multi-angle statistical analysis.Results A total of 4 479 patients with filamentous fungal infection were en-rolled.The proportion of male patients[57.5％(2 576/4 479)]was higher than that of female patients[42.5％(1 903/4 143)],mainly distributed in internal medicine,Intensive Care Unit(ICU)and emergency de-partment,among which internal medicine accounted for the highest proportion[50.0％(2 241/4 479)].About 90.0％of the specimens were from the lower respiratory tract,in addition to specimens from skin and soft tis-sue,tissue,ear and blood culture.In terms of seasonal distribution,there are more patients in winter.The fun-gi were mainly composed of Aspergillus,Mucor,Cerdosporium,Fusarium and Penicillium,among which As-pergillus was the most abundant,accounting for 74.6％of the total.Aspergillus fumigatus was the most a-bundant Aspergillus,accounting for 42.5％of the total Aspergillus(1 418/3 340).Among the related infec-tions caused by mold,Aspergillus was the most common in the lower respiratory tract,accounting for 76.8％.Among them,Aspergillus fumigatus accounted for the highest proportion(33.6％).98.6％of the molds infected the ear were Aspergillus,of which Aspergillus niger and Aspergillus terreus were the most common.Skin infections are mainly caused by Sporothrix schenckii,Trichophyton rubrum,Microsporum ca-nis.The results of in vitro drug sensitivity test showed that the four common Aspergillus isolated in this hos-pital were sensitive to voriconazole,and amphotericin B had better antifungal activity against Mucorales in vitro.Conclusion Based on the main epidemiological characteristics of fungal infections in this hospital,it is recommended that special attention be paid to the admission of patients in the respiratory department during the peak infection period in autumn and winter.In the treatment of fungal infections in different regions and on different body parts,attention should be paid to the differences in the distribution of bacterial species.

Objective To evaluate the changes of bronchial mucosa observed by fiberoptic bronchoscopy after bronchial arterial embolization(BAE)treatment.Methods A total of 176 patients,who received BAE at the First Affiliated Hospital of Guangzhou Medical University of China from May 2019 to March 2024,were enrolled in this study.The pre-BAE and post-BAE bronchial mucosa was checked by fiberoptic bronchoscopy.Results Of the 176 patients,fiberoptic bronchoscopy showed no abnormal findings in 143 and showed abnormal findings in 33.All the abnormal findings were mucosal congestion and oedema,in some cases coexisting vascular bulge was seen,but no manifestations of ischemia or necrosis of the bronchial mucosa could be found.In 22 patients,the preoperative and postoperative 7-day fiberoptic bronchoscopy revealed that both preoperative and postoperative examinations showed no obvious abnormalities of the bronchial mucosa in 13 patients,preoperative examination had abnormalities of the bronchial mucosa in 9 patients,postoperative examination showed no obvious abnormalities of the bronchial mucosa in 3 patients,and in one patient the postoperative degree of bronchial mucosal congestion and oedema was significantly improved when compared with its preoperative degree.Conclusion BAE does not cause ischemic necrosis or shedding of bronchial mucosa,and BAE can reduce the degree of bronchial mucosal congestion in some patients.

With the process of China’s aging population intensifying， palliative care， as an important guarantee for improving the quality of life of terminally ill patients， is receiving more and more social attention， and the demand is constantly increasing. Palliative care needs versatile professionals， and general education can enhance people’s awareness and understanding of it， enabling more people to understand， accept， and participate in palliative care. With the advancement of knowledge and technology in palliative care， the traditional cramming education models are no longer able to meet the actual needs. Therefore， there is an urgent need to innovate palliative care education strategies. By analyzing the current problems in the general education of palliative care in China， this paper proposed thoughts and suggestions for general and innovative education of palliative care in several aspects， such as establishing general and innovative education systems and evaluation systems of palliative care， diversifying educational contents and methods， strengthening medical staffs training， promoting diversified student groups， and strengthening the popularization of palliative care knowledge among the public.

Objective:To investigate the relationship between thyroid autoimmunity and pregnancy outcome in patients with unexplained recurrent abortion.Methods:A retrospective cohort study of 354 patients with normal thyroid function with recurrent abortion of unknown cause admitted to Sun Yat-sen Memorial Hospital, Sun Yat-sen University from January 2015 to June 2022 was used to detect thyroid antibody and thyroid function levels during pregnancy or early pregnancy. They were divided into TAI group ( n=144) and non-TAI group ( n=210) according to whether thyroid autoimmunity (TAI) was complicated or not. Tracking pregnancy outcomes. Results:Compared with the non-TAI group, the TAI group had a higher proportion of pregnancy outcomes resulting in miscarriage [42.4%(61/144) vs 27.1%(57/210), P=0.004]. In patients with unexplained recurrent abortion, TAI significantly increased the risk of spontaneous abortion [ OR(95% CI): 2.13(1.34, 3.41), P=0.001]. Positive TPOAb or TgAb also increased the risk of spontaneous abortion [ OR(95% CI): 2.18(1.37, 3.50), P=0.001; OR(95% CI): 2.33(1.31, 4.13), P=0.004]. TAI, TPOAb and TgAb had no significant interaction with age ( P=0.482, 0.724, 0.740). Conclusions:TAI is positively associated with the risk of spontaneous abortion in patients with unexplained recurrent abortion. TAI may be a potential risk factor for unexplained recurrent abortion, expanding the diagnosis and treatment of unexplained recurrent abortion.

Objective:This study focuses on the use of narrative medical records in palliative care teams and analyzes text from cases.The goal is to establish a foundation for standardizing and structuring narrative content, providing guidance for incorporating future narratives into medical record writing.Methods:Three cases of narrative medical records from the palliative care team at Peking Union Medical College Hospital were chosen for text analysis to demonstrate the clinical significance of narrative medical records within palliative care teams.These records included medical consultation records, social work service records, and disease progress records, authored by nurses, social workers, and doctors, respectively.Results:Our study discovered that narrative medical records demonstrate traits such as structured writing, cooperative writing, and comprehensive documentation.Furthermore, the narrative information contained in these records can be efficiently organized and condensed.Conclusions:By examining the cases and utilization of narrative medical records in the healthcare community, we emphasize the potential benefits of incorporating narrative elements into existing medical documentation.These results offer valuable insights for enhancing medical education in the future.

Specific tumor-targeted gene delivery remains an unsolved therapeutic issue due to aberrant vascularization in tumor microenvironment (TME). Some bacteria exhibit spontaneous chemotaxis toward the anaerobic and immune-suppressive TME, which makes them ideal natural vehicles for cancer gene therapy. Here, we conjugated ZIF-8 metal-organic frameworks encapsulating eukaryotic murine interleukin 2 (Il2) expression plasmid onto the surface of VNP20009, an attenuated Salmonella typhimurium strain with well-documented anti-cancer activity, and constructed a TME-targeted Il2 delivery system named Il2/ZIF-8@Salmonella. Both in vitro and in vivo experiments demonstrated that Il2/ZIF-8@Salmonella maintained the tumor-targeting feature of bacteria, and could be effectively phagocytosed by intratumoral macrophages, thus leading to the expression and secretion of IL2 in TME. The detailed analysis of tumor immune microenvironment (TIME) showed that one dose of combinatorial Il2/ZIF-8@Salmonella achieved synergistic actions on a potent remodeling of TIME, marked by the activation of cytotoxic T cells and M1-polarization of macrophages in TME, thus leading to significant anti-tumor effects in melanoma, orthotopic hepatocellular carcinoma, and pulmonary metastasis models. More importantly, Il2/ZIF-8@Salmonella exhibited high safety to major organs and hematopoietic systems. Taken together, we report a novel plasmid/ZIF-8@Salmonella system that simultaneously achieves effective TME-targeted delivery of therapeutic gene, as well as synergistic re-activation of TIME.

The incidence rate of chronic hepatitis B remains high in China. Antiviral therapy can significantly reduce the risk of progressive liver disease and hepatocellular carcinoma in patients with chronic hepatitis B. However, all current antiviral treatments can only inhibit HBV replication and not completely eliminate the hepatitis B virus, so antiviral therapy for chronic hepatitis B is probably a long-term or even lifelong treatment. Antiviral therapy compliance is essential for achieving long-term clinical benefits and preventing nucleot(s)ide drugs resistance. Herein, we analyzed the relevant factors of antiviral therapy compliance and their impact on CHB treatment and explored feasible programs that can improve compliance with nucleot(s)ide drug treatment by conducting a literature search using PubMed and Scopus with search terms including hepatitis B, compliance, nucleot(s)ide drugs, antiviral therapy, viral suppression, and drug resistance.

Thoracentesis is common in daily medical practice. During the operation, it is easy to cause complications such as re-expansion pulmonary edema, pulmonary hypotension, liver and spleen injury, pleural reaction, intercostal artery injury, pneumothorax, and so on. If the operator does not master procedures properly, it is easy to damage the thoracic organs. Therefore, the department of the general practice of the First Hospital of Jiaxing improved the puncture needle device based on thoracic puncture cannula, developed a new type of disposable thoracic puncture cannula, and obtained the National Utility Model Patent of China (patent number: ZL 2019 2 2112955.7). New type of disposable thoracic puncture cannula comprises a flexible puncture cannula, a steel needle, a limit structure, and a second bolt. In the process of puncture, the length of the puncture is limited by the limit structure. If the puncture force is too strong, the limit structure will prevent further penetration of the needle. The device is easy to use, flexible to operate, easy to master, and can reduce the risk of thoracentesis, which is worth of clinical promotion.
