ObjectiveTo investigate the efficacy and safety of cinobufagin tablets combined with thalidomide/dexamethasone （TD） regimen in the treatment of newly diagnosed multiple myeloma （NDMM） with phlegm and stasis obstruction. MethodsThe clinical data of 50 patients with NDMM of phlegm and stasis obstruction who were hospitalized at the Jiangsu Province Hospital of Chinese Medicine from June 1st， 2015 to July 31th， 2019 were retrospectively analyzed， and they were divided into a control group （bortezomib/dexamethasone-containing regimen， 27 cases） and an observation group （cinobufagin tablets combined with TD regimen， 23 cases）. The clinical efficacy and safety were compared between the two groups after two or three courses of treatment. The primary outcomes were clinical remission rate including overall response rate and deep remission rate， one-year and two-year overall survival rate， and adverse effects. The secondary outcomes were the proportion of plasma cells in bone marrow， hemoglobin， β2-microglobulin， lactate dehydrogenase， serum creatinine， blood urea nitrogen， bone pain score， and KPS functional status score （KPS score） before and after treatment. ResultsIn terms of clinical efficacy， there was no statistically significant difference （P＞0.05） in the overall response rate ［the observation group 69.57%（16/23） vs the control group 70.37% （19/27）］ and deep remission rate ［the observation group 56.52% （13/23） vs the control group 55.56% （15/27）］ between groups after the treatment. The one-year overall survival rates of the observation group and the control group were 90.9% and 92.4%， and the two-year overall survival rates were 81.8% and 80.9% respectively， with no statistically significant differences between groups （P＞0.05）. During the treatment， no renal function injury occurred in both groups. The incidence of peripheral nerve injury in the observation group was 8.70%， which was lower than 48.15% in the control group （P＜0.01）. After the treatment， the proportion of myeloma plasma cells， β2-microglobulin， serum creatinine level， and bone pain score decreased， while the hemoglobin level and KPS score increased in both groups （P＜0.05 or P＜0.01）. Compared between groups after treatment， the bone pain score of the observation group was lower than that of the control group， while the KPS score was higher than that of the control group （P＜0.05）. ConclusionThe clinical efficacy of cinobufagin tablets combined with TD in the treatment of NDMM is equivalent to bortezomib/dexamethasone-containing regimen， but the former is more helpful in relieving the pain and improving the quality of life， and has better safety.

Objective:To explore the effects of home hospice care team service model in patients with end-stage malignant tumors and main caregivers, so as to provide intervention programs for improving the quality of life of patients with end-stage malignant tumors.Methods:In the prospective and controlled study, 106 patients with malignant tumors who received end-stage hospice care in Yuebei People′s Hospital and main caregivers from May 2021 to July 2021 were selected by convenience sampling method, and divided into trial group (53 pairs) and control group (53 pairs) according to the random number table method. The control group was treated with routine nursing intervention, and the trial group was given home hospice care team service model intervention based on the control group. The occurrence of falls and negative emotions and quality of life of patients, psychological stress of primary caregivers before and after intervention were observed by using Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Relative Stress Scale (RSS) and European Organization for Research and Treatment of Cancer Quality of Life Scale (EORTC QLQ-C30).Results:Finally, 103 patients and main caregivers completed the study, with 52 pairs in the control group and 51 pairs in the trial group. In the control group, the patients were 29 males and 23 females, aged (54.33 ± 12.24) years old,and the main caregivers were 22 males and 30 females, aged (41.67 ± 8.14) years old. In the trial group,the patients were 27 males and 24 females,aged (55.17 ± 10.56) years old,and the main caregivers were 24 males and 27 females, aged (43.62 ± 7.39) years old. After intervention, the total incidence of falls and the total incidence of fall complications in the trial group were 7.84% (4/51) and 1.96% (1/51), respectively, which were lower than 25.00% (13/52) and 11.54% (7/52) in the control group, the differences were statistically significant ( χ2=5.50, 4.75, both P<0.05). There was no significant difference in the score of SAS, SDS, RSS, EORTC QLQ-C30 before intervention between the two groups (all P>0.05). After intervention, the scores of SAS and SDS in trial group were (32.66 ± 3.18), (31.19 ± 4.50) points,which lower than those in control group (34.54 ± 3.91), (34.31 ± 4.03) points, the differences were statistically significant ( t=2.67, 2.51, both P<0.05). After intervention, the RSS scores of psychological distress, life disruption, negative emotion and total score of the main caregivers in trial group were (3.52 ± 0.48), (3.66 ±0.56), (3.47 ± 0.82), (10.65 ± 0.67) points, which were lower than those in the control group (4.74 ± 2.75), (4.67 ± 2.64), (4.12 ± 2.13), (13.53 ± 2.26) points, the differences were statistically significant ( t values were 2.04-8.73, all P<0.05). After intervention, the EORTC QLQ-C30 score in the trial group was (74.14 ± 5.64) points, which was lower than that in the control group (70.54 ± 7.07) points, the difference was statistically significant ( t=2.85, P<0.05). Conclusions:The application of home hospice care team service model can effectively reduce the risk of falls in patients with malignant tumor chemotherapy, improve the negative emotions of patients and the psychological stress state of their main caregivers, and improve the quality of life 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.

Objective:The aim of this study is to develop a comprehensive index system for assessing the key first aid skills required for aeromedical evacuation of infected patients, with the goal of enhancing our army's medical support capabilities.Methods:This study combined literature review and two rounds of Delphi expert correspondence to construct the key first aid skills index system of aeromedical evacuation for infected patients. 19 experts from relevant disciplines were selected purposively to conduct Delphi expert consultation.Results:Both rounds of Delphi expert correspondence achieved a 100% response rate, indicating high effectiveness. The degree of authority among the experts was determined to be 0.87. In the first round, there was a Kendall coordination coefficient value of 0.184 for assessing the importance of primary indicators, while secondary indicators showed coefficients of 0.289 and 0.380 for importance and feasibility respectively. In the second round, these values increased slightly to 0.263, 0.304 (importance) and 0.398 (feasibility), respectively. The final evaluation index system of key first aid skills applied to the aeromedical evacuation of infected patients was constructed, including 3 primary indicators of life support technology, intensive care technology and isolation protection technology, and 40 secondary indicators.Conclusion:The evaluation index system of key first aid skills applied to the aeromedical evacuation of infected patients constructed through two rounds of Delphi expert correspondence is scientific and reasonable, which can provide reference for the training and assessment of key first aid skills applied to the aeromedical evacuation of infected patients, so as to promote the development of aeromedical evacuation for infectious patients in China.

This paper summarizes the experience of professor DING Yuanqing in treating post-stroke depression （PSD） of young and middle-aged patients with the method of regulating qi and promoting blood circulation. PSD is a syndrome resulting by vascular injury and impairment of brain marrow and vital activity after the stroke. Factors such as poor lifestyle， improper control of chronic diseases and sleep disorders，etc.，which can be harmful individually， or they can interact. Over time，these factors can block yang of defensive qi，obstract blood circulationg and disturb qi movement. Reverse ascending of defensive qi can generate wind and fire，generate phlegm and stasis from the fluid the blood. Qi stagnation， phlegm and stasis can combined with stagnation heat， phlegm heat， blood stasis heat which caused by stroke ， which can further aggravate pulse accumulation， damage the blood vessels and block the collaterals. Consequently， defensive qi is floating over and nutrient qi is not smooth， resulting in inadequate nourishment of the brain marrow，and disfunction of vital activity， causing depressive symptoms. Professor DING innovatively applied the method of regulating qi and promoting blood circulation. He selected the classic prescriptions such as Guizhi Decoction（桂枝汤）， Baoyuan Decoction（保元汤）， as well as self-fitting prescriptions like Erdan Decoction（二丹汤）， Erzhu Decoction（二竹汤）， to relieve qi and tonify qi，promote harmonious blood circulation， facilitate vasodilation， ease symptoms of depression， invigorate the mind， and provide an effective treatment for PSD.

ObjectiveTo explore the effect and mechanism of Sishenjian on synovial lesions induced by monosodium iodoacetate （MIA） in rats with knee osteoarthritis （KOA）. MethodSixty female Sprague-Dawley （SD） rats were randomly divided into the following six groups： normal group， model group， celecoxib group， and high-， medium-， and low-dose Sishenjian group. The KOA rat model was established by intra-articular injection of MIA. Celecoxib （18 mg·kg^-1） and Sishenjian （14.4， 7.2， 3.6 g·kg^-1） were administered by gavage according to the groups. All rats were euthanized after four weeks of continuous administration. The transverse diameter of the bilateral knee joints of rats was measured， and gross observation of the knee joint was performed. Pathological changes in knee joint synovial tissue were observed by hematoxylin-eosin （HE） staining and picrosirius red staining. Immunohistochemistry （IHC） was used to detect the expression of vascular endothelial growth factor A （VEGFA） in synovial tissue. The levels of inflammatory cytokines in the joint synovial fluid were detected by enzyme-linked immunosorbent assay （ELISA）. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the expression of mRNA and proteins related to the transforming growth factor-β₁ （TGF-β₁）/Smad2/3 pathway in knee joint synovium. ResultCompared with the normal group， the transverse diameter of the knee joint in the model group significantly increased （P<0.01）. Compared with the model group， the transverse diameter of the knee joint in rats of each Sishenjian group significantly decreased （P<0.01）. Compared with the normal group， the expression levels of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α） in the knee joint synovial fluid of model group significantly increased （P<0.01）. Compared with the model group， the expression levels of IL-1β and TNF-α in the knee joint synovial fluid of rats in each Sishenjian group significantly decreased （P<0.01）. Compared with the normal group， the expression levels of TGF-β₁， Smad2/3， phosphorylation（p）-Smad2/3， type Ⅰ collagen α1 （ColⅠ_α1）， type Ⅲ collagen α1 （ColⅢ_α1）， VEGFA proteins and TGF-β₁， Smad2/3， ColⅠ_α1， ColⅢ_α1 mRNA in knee joint synovium of model group significantly increased （P<0.01）. Compared with the model group， the expression levels of TGF-β₁， Smad2/3， phosphorylation （p）-Smad2/3， ColⅠ_α1， ColⅢ_α1， VEGFA proteins and TGF-β₁， Smad2/3， ColⅠ_α1， ColⅢ_α1 mRNA in knee joint synovium of rats in each Sishenjian group significantly decreased （P<0.05， P<0.01）. ConclusionSishenjian can inhibit synovial inflammation and angiogenesis， and may become a potential drug for treating synovial lesions in KOA by regulating the TGF-β₁/Smad2/3 pathway.

Objective:To construct core medical skill index system for helicopter medical rescue personnel by Delphi expert consensus method.Methods:This study combined literature review and two rounds of Delphi expert correspondence to construct the core skill index system. Total of 22 experts from relevant disciplines were selected purposively to conduct Delphi expert consultation.Results:The effective questionnaire recovery rates of the two rounds of Delphi expert correspondence was 100%; the authority coefficient of experts was 0.87; the Kendall coordination coefficients of the importance of the first and second level indexes were 0.380 and 0.338 in the first round of correspondence, and then 0.415 and 0.357 in the second round. the Kendall coordination coefficients of the feasibility of the second level indexes were 0.347 in the first round of correspondence and 0.354 in the second round. The final core skill index system for helicopter medical rescue personnel includes 4 primary indicators: core medical skill for diseases or trauma in respiratory system, circulatory system, sports system and other system, and 32 secondary indicators.Conclusions:The core medical skill index system for helicopter medical rescue personnel constructed through two rounds of Delphi expert correspondence is scientific and reasonable, which can provide a scientific basis to accurately understand, describe, analyze, and evaluate the competence level of helicopter medical rescue personnel, as well as serve as a content framework for training programs.

Objective:To systematically evaluate the correlation between chronic periodontitis and postmenopausal osteoporosis (PMOP).Methods:Electronic searches were conducted on Cochrane Library, Pubmed, Embase, Ovid, CNKI, CBM, VIP, and WF databases to collect research literature on the correlation between chronic periodontitis and PMOP. The Newcastle Ottawa Scale (NOS) criteria were used to evaluate the quality of the included literature, and RevMan 5.3 software was used for meta-analysis. The outcome measures were clinical attachment loss (CAL), probing depth (PD), plaque index (PI), calculus index (CI), bleeding on probing (BOP), and simplified oral hygiene index (OHI-S).Results:A total of 16 articles were included, with a total of 1587 patients. Compared with the postmenopausal non osteoporosis group, the osteoporosis group showed significant abnormalities in CAL [standardized mean difference (SMD)=1.09, 95% CI: 0.62-1.57, P<0.001], PD(SMD=0.71, 95% CI: 0.28-1.14, P<0.001), PI(SMD=0.43, 95% CI: 0.29-0.56, P<0.001), and OHI-S(SMD=0.28, 95% CI: 0.22-0.35, P<0.001) indicators, as well as in BOP(SMD=0.01, 95% CI: -0.48-0.49, P=0.97) and GI(SMD=0.01, 95% CI: -0.48-0.49, P=0.97). At the level of 0.24 and 95% CI: -0.34 to 0.81, P=0.42, there was no statistically significant difference. Conclusions:Women with PMOP exhibit more significant changes in indicators such as CAL, PD, PI, and OHI-S, suggesting that postmenopausal women with osteoporosis are more likely to suffer from periodontitis.

Objective:To analyze the occurrence of and risk factors for skin and mucosal infections after primary tumor resection in patients with paraneoplastic pemphigus, and to summarize relevant nursing experience.Methods:Clinical characteristics and postoperative skin and mucosal infections were retrospectively analyzed in patients with confirmed paraneoplastic pemphigus, who underwent primary tumor resection in Department of Dermatology, Peking University First Hospital between January 1999 and January 2021. Common infectious agents were analyzed, and infection-related risk factors were identified by logistic regression analysis.Results:A total of 44 patients with paraneoplastic pemphigus were included in this study, including 25 (56.8%) males and 19 (43.2%) females, and their age were 33.8 ± 15.4 years. Postoperatively, 21 (47.73%) patients developed skin and mucosal infections, and their postoperative hospital stay (median [ Q1, Q3]) was 38 (25, 60) days, which was significantly longer than that in patients without skin and mucosal infections (21 [12, 23] days, Z = -4.08, P < 0.001) . The most common pathogen was methicillin-resistant Staphylococcus aureus (15 cases, 34.09%) . High glucocorticoid dosage per kilogram of body weight ( OR = 1.21, 95% CI: 1.00 - 1.46, P = 0.047) and receiving assisted ventilation therapy ( OR = 9.20, 95% CI: 2.01 - 42.13, P = 0.004) were independent risk factors for postoperative skin and mucosal infections. After active treatment and care, 37 (84.1%) patients recovered well at discharge. Conclusion:Skin and mucosal infections are a common postoperative complication in patients with paraneoplastic pemphigus, and the pathogens are mostly drug-resistant bacteria, which can lead to prolonged hospital stay, so attention should be paid to postoperative skin care; high postoperative glucocorticoid dosage per body weight and respiratory support may be associated with postoperative skin and mucosal infections.
