Objective:To investigate the status quo of pain management for cancer patients in hospice care wards of community health service centers.Methods:The electronic medical records of 373 cancer patients admitted in hospice wards of Kangjian Community Health Center of Xuhui District and Jinshanwei Town Community Health Center of Jinshan District from January 2015 to July 2021 were collected. The characteristics of cancer pain, the use of analgesic drugs, the effects of analgesic drugs and its influencing factors were analyzed.Results:The incidence of cancer pain in 373 patients was 93.0% (347/373), and the proportion of moderate to severe cancer pain was 55.6% (193/347). Analgesics were used in 304 patients, among whom 233 (76.6%) patients used oral analgesics, 297 (97.7%) used on time, 97.6%(285/292) used sustained-release opioids, and 94 (30.9%) used combinedly. Breakout pain occurred in 100 cases (32.9%), all of which was controlled with immediate-release morphine. Cancer pain was not relieved in 132 cases (43.42%), and multivariate logistic regression analysis showed that the pain degree on admission (moderate: OR=3.69, 95 %CI:2.09-6.49; severe: OR=5.52, 95 %CI:2.43-12.53), the presence of burst pain ( OR=3.28, 95 %CI:1.77-6.06), the type of analgesics used (non-steroidal+weak opioids: OR=0.39, 95 %CI:0.20-0.76; nonsteroidal+strong opioids: OR=0.20, 95 %CI:0.08-0.51) and the adverse reactions ( OR=1.92, 95 %CI:1.03-3.60) were the influencing factors of pain relief in cancer pain patients (all P<0.05). Conclusion:The pain of cancer patients admitted to community palliative care wards cannot be ignored. Although most cancer pain patients use analgesic drugs in a standard way, there are still a high proportion of patients whose pain is not controlled. Various factors affect the effect of analgesic treatment.

Objectives To generate an orthotopic left lung transplantation model in mice, and to observe the early changes of respiratory system resistance andγδT lymphocytes infiltrated in grafts? Methods The research time was from March 2014 to May 2015? The male C57BL/6 mice ( n=35) and BALB/c mice (syngenic group,n=10) were randomly divided into five groups. Control group (n=5): wild C57BL/6 mice; syngenic transplant group ( n=10 ): C57BL/6→C57BL/6; allogenic transplant group ( allogenic group,n=10): BALB/c→C57BL/6; each transplant group was randomly divided into 3?day and 7?day subgroups ( n=5 )? Respiratory system resistance and histological features of grafts were assessed, and differences in graft infiltrating γδT lymphocytes and mRNA expression of interleukin ( IL )?17A were quantified on 3 and 7 days after transplantation? Multiple comparisons were performed using one?way analysis of variance and least significant difference analysis? Results ( 1 ) The respiratory system resistance of syngenic group and allogenic group were (2?61±0?59) cmH2O·s/ml and (2?84±0?31) cmH2O·s/ml 3 days post?operation, both of them increased compared to control group (1?39±0?17) cmH2O·s/ml (1 cmH2O=0?098 kPa) (P=0?001, 0?000). The respiratory system resistance of allogenic group were (4?33±0?67) cmH2 O·s/ml 7 days post?operation, which was significantly higher than that of syngenic 7?day subgroup (1?87±0?27) cmH2O·s/ml and control group (1?39±0?17) cmH2O·s/ml (P=0?000, 0?000)?(2) The isografts of syngenic group showed a relatively normal histological appearance with minimal infiltration of inflammatory cells, and the allografts of allogenic group infiltrated apparently by inflammatory cells, especially 7?day subgroup showed acute cellular rejection? ( 3) The percentage of γδT lymphocytes infiltrated in isografts and allografts were 3?90%± 0?86% and 4?40%± 0?57%, respectively, which were significantly increased compared to that of control lungs 2?00%±0?23% 3 days post?operation(P=0?000, 0?000);The percentage ofγδT lymphocytes infiltrated in 7 days allografts was 5?40%±0?98% , which was higher compared to that of 7 days isografts 2?60%± 0?54% and control lungs 2?00%± 0?23% ( P=0?000, 0?000)?

Objective:To construct an evaluation index system for community hospice comfort care.Methods:This was a cross-sectional study. Two rounds of expert consultations were conducted using modified Delphi method from June to September 2023, 14 experts in the field of palliative care nursing were invited to participate in the consultations. Based on the consultation results, an evaluation index system for comfort care of community hospice was preliminarily developed.Results:All consultation experts were females, with an average age of (48±8) years; 9 held senior professonal titles, and 12 had more than 5 years of palliative care-related working experiencs. The positive coefficient of correspondence in two rounds of consultations was 100%, and the degree of authority was 0.841 and 0.834, respectively. The expert coordination coefficients for the importance of secondary indicators were 0.281 (χ 2=182.65) and 0.284 (χ 2=132.98), and the expert coordination coefficients for the operability of secondary indicators were 0.231 (χ 2=150.12) and 0.252 (χ 2=118.01), respectively. The constructed evaluation index system of hospice comfort care consisted of 5 primary indexes and 32 secondary indexes. The five primary indexes were environmental comfort, physiological comfort, psychological comfort, spiritual comfort and social comfort with a weight coefficient of 0.202 3, 0.205 3, 0.205 3, 0.199 4 and 0.187 7, respectively. Conclusion:An evaluation index system for comfort care in community hospice has been preliminarily developed in this study, after validation it would provide a reference for assessing the comfort needs of patients with palliative care.

OBJECTIVETo highlight current knowledge about M-type phospholipase A2 receptor (PLA2R) which is the first human autoantigen discovered in adult idiopathic membranous nephropathy.

DATA SOURCESRelevant articles published in English from 2000 to present were selected from PubMed. Searches were made using the terms "idiopathic membranous nephropathy, M-type PLA2R and podocyte."

STUDY SELECTIONArticles studying the role of M-type PLA2R in idiopathic membranous nephropathy were reviewed. Articles focusing on the discovery, detection and clinical observation of anti-PLA2R antibodies were selected.

RESULTSM-type PLA2R is a member of the mannose receptor family of proteins, locating on normal human glomeruli as a transmembrane receptor. The anti-PLA2R in serum samples from MN were primarily IgG4 subclass. Technologies applied to detect anti-PLA2R autoantibody are mainly WB, IIFT, ELISA and so on. Studies from domestic and overseas have identified a strongly relationship between circulating anti-PLA2R levels and disease activity.

CONCLUSIONRecent discoveries corresponding to PLA2R facilitate a better understanding on IMN pathogenesis and may provide a new tool to its diagnosis, differential diagnosis, risk evaluation, response monitoring and patient-specific treatment.
