RESUMO
Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective To explore the bioactive constituents of Shufeng Jiedu capsule and its potential mechanism in the treatment of acute lung injury(ALI)via network pharmacology,bioinformatics analysis and molecular docking methods.Methods The bioactive constituents of Shufeng Jiedu capsule were searched from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)database.The putative targets of Shufeng Jiedu capsule were obtained from TCMSP and Swiss Targets Predicion website.Targets associated with ALI were obtained from 5 disease target prediction databases,including DisGeNET,GeneCard,Online Mendelian Inheritance in Man(OMIM),Therapeutic Target Database(TTD),and National Center for Biotechnology Information(NCBI).The intersecting targets between drug-related targets and disease-related targets were defined as potential therapeutic targets of Shufeng Jiedu capsules in the treatment of ALI.A regulative network among drug,ingredients and potential therapeutic targets was explored,and it was further visualized by Cytoscape 2.6.1 software.The key bioactive ingredients and core therapeutic targets were speculated according to the topological parameters.Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis was applied to the potential therapeutic targets.AutoDock Vina 1.1.2 was used to perform molecular docking and the docking results were visualized by PyMol software.Results A total of 170 bioactive constituents of Shufeng Jiedu capsule were obtained from TCMSP database,and 104 potential therapeutic targets of ALI were obtained in the present study.Quercetin,Luteolin,Wogonin,Kaempferol,and Acacetin were taken as putatively key constituents via the drug-ingredients-targets network.Prostaglandin endoperoxidase 2(PTGS2),nitric oxide synthase 2(NOS2),glycogen synthase kinase-3β(GSK-3β),PIM1 kinase and peroxisome proliferator-activated receptor gene(PPARG)were identified as the hub targets and hypoxia-inducible factor-1(HIF-1)pathway et al was considered as the key pathway of Shufeng Jiedu capsule through KEGG analysis.Molecular docking showed a stable affinity between the key compounds and the hub targets,confirming the accuracy of the network pharmacology screening results.Conclusion The mechanism of Shufeng Jiedu capsule in treating ALI involves multiple active ingredients,therapeutic targets,and signaling pathways,which can provide new ideas for the clinical treatment of ALI.
RESUMO
Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
RESUMO
OBJECTIVE@#Scutellarin is a primary active composition come from Erigeron breviscapus. It is well known that scutellarin has anti-inflammatory and antioxidant physiological functions. In this study, we detected the effects of scutellarin on hepatocyte cell apoptosis in type 2 diabetes mellitus (T2DM) rats.@*METHODS@#Sprague Dawley (SD) (6-8 weeks, 160-180 g) rats were randomly divided into six groups: control, model, scutellarin low-dose, medium-dose, high-dose treatment, and rosiglitazone positive groups; with 10 SD rats in each group (n = 10). The changes of biochemical factors in serum were detected by automatic biochemical instrument, the pathological changes of liver tissue were detected by hematoxylin and eosin (HE) staining, the apoptosis of liver tissue and cells was detected by tissue staining and flow analyzer, and the expression of apoptosis-related factors were determined by qPCR, Western blot and immunohistochemistry in liver tissues or cells.@*RESULTS@#The results showed that scutellarin decreased the levels of fasting blood glucose, total cholesterol, triglyceride, and low-density lipoprotein and increased the levels of high-density lipoprotein. Meanwhile, scutellarin decreased the levels of alanine transaminase (ALT) and aspartate transaminase (AST) and improved liver function. In addition, scutellarin suppressed the secretion of interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) and reduced hepatocyte apoptosis. Furthermore, scutellarin inhibited the expression of cleaved Caspase-3, Bax, and cytochrome C (Cyt-C) and promoted the expression of Bcl-2.@*CONCLUSION@#Scutellarin can inhibit the apoptotic pathway, thereby relieving T2DM.
RESUMO
Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

RESUMO
Objective:To evaluate the clinical value of 5.0 T ultra-high filed MRI system in assessing intracranial arteries segments and vessel branchers.Methods:This study was a prospective study. Totally 40 consecutive healthy volunteers were recruited from Zhongshan Hospital, Fudan University from September 1, 2021 to November 30, and all participants who underwent either 3.0 T or 5.0 T time-of-flight MR angiography (TOF-MRA) in random order were divided into 3.0 T MR group and 5.0 T MR group with 20 volunteers for each group. Image quality was assessed by Likert 5 scoring systems and signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR),and score in visualization of intracranial arteries [middle cerebral artery (MCA) and its segments, anterior cerebral artery (ACA) and its segments, posterior cerebral artery (PCA) and its segments, lenticulostriate arteries (LA) and pontine artery (PA)] were assessed from 0 to 3 (≥2: good depiction of vessel segment). Quantitative indicators were compared between 2 groups using independent t test or Mann-Whitney U test. Results:Among the 40 subjects, there were 29 males and 11 females, aged 20-69 (50±12) years. SNR and CNR were both significantly higher in 5.0 T MR group than those in 3.0 T MR group (SNR: 187±9 vs 91±4, t=31.59, P<0.001; CNR: 156±7 vs 70±4, t=31.45, P<0.001), but there was no significant difference in subjective scores of image quality between the 5.0 T MR and 3.0 T MR groups [5.0 (4.0, 5.0), 5.0 (5.0, 5.0) points, respectively, Z=-1.23, P=0.218]. In the evaluation of cerebral arteries, the visualizations of the proximal and middle segments of MCA, ACA and PCA was better than those in the 3.0 T MR group, and there was no significant difference in the scores ( P>0.05), while the visualizations of proximal arteries in the 5.0 T MR group were significantly better than those in the 3.0 T MR group ( P<0.05). Furthermore, small vessel branches such as LA and PA in 5.0 T MR group were visualized better than those in 3.0 T MR group ( P<0.001). Conclusion:TOF-MRA by ultra-high filed 5.0-T provides an optimal choice in visualization of distal large arteries and small vessel branches, which could be useful for the diagnosis on cerebral vascular disease.
RESUMO
Objective:To investigate the effect of irradiation on the expression of miR-150-5p and miR-23a-3p in human peripheral blood serum by collecting peripheral blood of tumor patients before and after radiotherapy, so as to provide scientific basis for finding radiation biomarkers.Methods:A total of 63 tumor patients treated with radiotherapy from October 2021 to March 2022 were enrolled in this study. The relative expression levels of miR-150-5p and miR-23a-3p in peripheral blood serum in these patients were detected using the real-time fluorescence quantitative PCR (qPCR) before and after radiotherapy. The differential changes in the expression levels of the two miRNAs in the peripheral blood serum of the patients before and after radiotherapy were compared, and their relationships with factors such as cancer types were analyzed.Results:The relative expression levels of miR-150-5p and miR-23a-3p in peripheral blood serum of the patients after radiotherapy were significantly lower than those before radiotherapy ( t = 4.97, Z = -2.77, P < 0.05). Among different cancer types, the relative expression level of miR-150-5p in the patients with breast cancer, esophageal cancer, or other digestive tract cancer decreased after radiotherapy ( t = 3.47, 2.47, 2.87, P < 0.05), and the relative expression level of miR-23a-3p in the patients with digestive tract cancer decreased after radiotherapy ( Z = -1.99, P < 0.05). The changes in the expression level of miR-150-5p before and after radiotherapy were not affected by gender, age, chemotherapy, and cancer type ( P > 0.05). By contrast, the changes in the expression level of miR-23a-3p before and after radiotherapy were significantly affected by gender, age, and chemotherapy ( t=2.04, -3.34, -2.29, P<0.05). Conclusions:The expression of miR-150-5p in the serum of tumor patients may be affected by radiotherapy, which has the potential to be used as a biological indicator of radiation.
RESUMO
Objective:To investigate chromosomal aberrations in peripheral blood lymphocytes of underground miners, in order to explore the influencing factors involved in chromosomal aberration levels of non-uranium metal mines.Methods:Totall 135 workers were recruited from an iron mine and a gold mine located in different cities of Henan province, where 69 workers worked aboveground and 66 miners worked underground in the metal mines. The radon concentration in the mines was measured by solid-state nuclear track detectors. Chromosomal aberrations in peripheral blood lymphocytes from the subjects were detected using conventional analysis method, and the influence factors of chromosomal aberrations were analyzed.Results:Radon concentration was 30-2 943 Bq/m 3 in the aboveground workplace of the mines, and 62-28 314 Bq/m 3 in underground. The age of the underground group was obviously lower than that of the aboveground group( t=2.12, P<0.05), but the frequencies of dicentrics, translocation, acentric fragment, and total chromosome-type aberrations in the underground group were significantly higher than those in the aboveground group ( χ2=10.49, 16.74, 8.15, 29.50, P<0.01). Consistent results were obtained when only male workers were regarded as object of observation ( χ2=8.44, 11.63, 4.94, 20.81, P<0.05). The frequency of translocation ( χ2=8.44, P<0.05) was dependent on the length of service in the underground group. Poisson regression analysis indicated that the aboveground and undergroud grouping partly affected the levels of dicentrics, translocation, acentric fragment, and total chromosome-type aberrations (the underground group IRR=3.25, 2.69, 1.97, 2.18, P<0.05). Conclusions:The radon exposure in the underground workplace of the metal mines may be the main factor resulting in the increase of chromosome-type aberrations of miners. The occupational health and safety of the miners who may be exposed to high radon levels are worthy of great attention.

The experimental group participated in physical activities for 10 weeks (3 times a week, 1 hour each time) in the preset outdoor field (each physical activity was composed of 30 minutes of autonomous physical activity and 30 minutes of structured physical activity), while the control group had no intervention of site preset and specially designed activities. Before and after the experiment, 9 basic motor skills (including 3 fine motor skills and 6 gross motor skills) were tested.@*Results@#There were significant differences in double hand throwing, single leg balance (left), single leg balance (right), swing bridge balance and beam walking before and after intervention in experimental group(t=7.82,4.25,9.69,-10.01,-28.28,P<0.05), but there was no statistical significance in the improvement of heel toe coordinated walking(t=-0.60,P>0.05). There was no significant improvement in coin throwing (right hand), coin throwing (left hand) and square stacking(t=0.91,1.03,0.42,P>0.05), while in the control group, except for the balance of swinging bridge(t=4.27,P<0.05) and heel and toe walking(t=3.96,P<0.05), the improvement of other basic motor skills was not statistically significant(t=1.21, 0.74, 0.31, 0.97,P>0.05).@*Conclusion@#The quality of sports environment has a potential impact on the basic motor skills of preschool children. The basic motor skills of the pre-school children can be greatly improved by conducting structural and autonomous physical activities with a certain time and frequency.
RESUMO
Objective:To determine whether the neutrophil-lymphocyte-ratio (NLR) a inflammatory factor can predict tumor response to neoadjuvant chemoradiotherapy (CRT) in locally advanced rectal cancer.Methods:Between 2014 and 2019, 205 locally advanced rectal cancer patients underwent CRT before curative surgery. After propensity score matching, 148 patients (74 matched pairs) were enrolled in this study. The hematological parameters were collected and their relationship with tumor response was investigated.Results:After propensity score matching, NLR before CRT in good response group were significantly lower than that in poor response group(2.2±1.0 vs. 2.4±1.2, Z=-2.465, P<0.05), while there was no significant difference in all hematological characteristics between two groups after CRT. The cutoff values of pre-CRT NLR was 3.88 after receiver operating characteristic analysis(AUC=0.618, 95% CI: 0.528-0.708). Multivariate analysis model indicated that pre-CRT NLR≥3.88 was the predictor of poor tumor response ( OR=5.826, 95% CI: 1.299-26.132, P<0.05). Conclusion:The increased NLR before CRT can be regarded as a hematological factor for poor tumor response in locally advanced rectal cancer.
RESUMO
Objective:To evaluate the efficacy of preoperative interview with humanistic care in patients undergoing resection of tumor.Methods:Two hundred patients, aged 35-64 yr, with body mass index of 18-28 kg/m 2, of American Society Anesthesiologists physical status Ⅰ or Ⅱ, undergoing elective laparoscopic gastrointestinal tumor resection, were divided into 2 groups ( n=100 each) by a random number table method: conventional preoperative interview group (group C) and preoperative interview with humanistic care group (group H). Pre-interview anxiety was assessed using the Self-Rating Anxiety Scale (SAS) at 1 day before the interview (T 0), and pre-interview heart rate (HR) and mean arterial pressure (MAP) were recorded, followed by a preoperative interview.Conventional preoperative interview was given in group C, and preoperative interview with humanistic care was given in group H. Anxiety was assessed again after interview (T 1) and HR and MAP were recorded at 24 h. Venous blood samples were collected for determination of plasma norepinephrine (NE) and cortisol (Cor) concentrations by enzyme-linked immunosorbent assay at T 0 and T 1. Results:Compared with group C, the MAP, HR and SAS scores were significantly decreased at T 1, the incidence and degree of anxiety and plasma NE and Cor concentrations were decreased at T 1, and the incidence of abnormalities of MAP, HR and plasma Cor concentrations were decreased in group H ( P<0.05). Conclusion:Preoperative interview with humanistic care can alleviate the post-interview anxiety and reduce the over-stress response in patients undergoing resection of tumor.
RESUMO
Porcine deltacoronavirus (PDCoV) is an emerging swine enteric coronavirus that causes diarrhea in piglets. However, the biological characteristics of PDCoV are unclear. In this study, the hemagglutination (HA) abilities of two PDCoV strains (CH-01 and HNZK-04) were investigated. Our results showed that PDCoV has the ability to agglutinate rabbit erythrocytes after virion pretreatment with trypsin or neuraminidase. Additionally, the HA assay results showed a significant positive correlation with the infectious viral titer. Our results suggest that assessing the HA activity of PDCoV may be a useful diagnostic method for investigating and surveilling PDCoV infections.

That was, cIMT values increased with the number of abnormal metabolic indexes (Ptrend<0.001).@*Conclusion@#Abdominal obesity, elevated blood pressure, total triglyceride, fasting glucose and clustering of the above factors are associated with cIMT.
RESUMO
OBJECTIVE： To investigate the effects of rosuvastatin on in-stent restenosis in middle-aged patients with acute coronary syndrome（ACS）after percutaneous coronary intervention （PCI）. METHODS： Totally 400 middle-aged ACS patients underwent PCI were selected from Xuchang Central Hospital during Mar. 2016 to Apr. 2017， and then divided into control group and observation group according to random number table， with 200 patients in each group. Both groups were given conventional drugs for secondary prevention of coronary heart disease. Control group were given Clopidogrel hydrogen sulfate tablets 75 mg， once a day+Aspirin enteric-coated tablets 100 mg， once a day+Atorvastatin calcium tablets 20 mg， once at bed time every day orally after PCI. Observation group was given Clopidogrel hydrogen sulfate tablets 75 mg， once a day+Aspirin enteric-coated tablets 100 mg， once a day+Rosuvastatin calcium tablets 10 mg， once at bed time every day orally after PCI. Both groups were treated for consecutive 12 months. The serum levels of TG， TC， LDL-C， hs-CRP and IL-35 were recorded in 2 groups before surgery， 1， 3， 6 and 12 months after surgery； in-stent minimum lumen diameter （MLD） was observed immediately after surgery and 12 months after surgery. The occurrence of in-stent restenosis， major adverse cardiovascular events （MACE） and adverse drug reaction （ADR） were recorded. RESULTS： Totally 14 patients dropped out from control group and 18 from observation group， and 368 patients completed the study. Before surgery and immediately after surgery， there was no statistical significance in the serum levels of TG， TC， LDL-C， hs-CRP IL-35 or MLD （P＞0.05）. One day after surgery， the levels of hs-CRP were increased significantly in 2 groups， compared with before surgery （P＜0.05）. One， three， six and twelve months after surgery， the serum levels of TG， TC， LDL-C and hs-CRP were decreased significantly in 2 groups， while the levels of IL-35 were increased significantly， compared with before surgery； and the serum levels of TG and TC （1 and 3 months after surgery）， LDL-C （3 and 6 months after surgery） and hs-CRP （1 month after surgery） in observation group were significantly lower than control group； the level of IL-35 in observation group （1 month after surgery） was significantly higher than control group （P＜0.05）. Twelve months after surgery， MLDs of 2 groups were decreased significantly， and observation group was significantly higher than control group （P＜0.05）. There was no statistical significance in the incidence of in-stent restenosis or the total incidence of MACE and ADR between 2 groups after surgery （P＞0.05）. CONCLUSIONS： Rosuvastatin can effectively improve the levels of blood lipid and inflammatory factor in meddle-aged patients with ACS after PCI， and its effect is better than that of atorvastatin. The drug can delay in-stent restenosis after PCI in these patients， which is better than the effect of atorvastatin. At the same time， rosuvastatin can not increase the risk of MACE and ADR with good safety.
RESUMO
Objective The primary goal of this work is to discuss the molecular mechanism of multi-drug resistant Pseudomonas spp. resistance to carbapenam and aminoglycoside antibiotics. Methods From June 2012 to March 2013, six strains of P. aeruginosa and P. putida producing carbapenemasefrom 4 different district were collected. Species identification was performed using VITEK-2 compact system and by sequencing of 16S rDNA amplicons. Minimum inhibitory concentrations were determined by E-test method. Production of carbapenemase were detected by Carba NP method. Carbapenemase genes and aminoglycoside 16s rRNAmethylase genes were screened by PCR, and their subtypes combined with their immediate genetic context were worked out by assemble the sequence of overlapped PCR amplicons. SpeI-PFGE (Pulse field gel electrophoresis after SpeI enzyme digestion) were conducted to evaluate their clonal relatedness. S1-PFGE (Pulse field gel electrophoresis after S1 enzyme digestion) were conducted to conform the relatedness of plasmids they carried. Results Three multidrug resistant P. aeruginosa and three P. putida, were all positive for Carba NP test and conformed producing class B carbapenemase. PCR screening followed by sequencing confirmed carriage of blaIMP-45 and armA, which confer resistance to β-lactams (except aztreonam) and aminoglycosides. These two genes co-located in a Tn1548-associatedregion. SpeI-PFGE disclosed that these isolates were not clonal closely related to each other, except two P. aeruginosa isolates were clonal related. S1-PFGE results showed that these isolates all carried plasmids of large size (300-600 kb). Conclusions This study showed that Pseudomonas spp. isolates co-carried blaIMP-45 and armA were disseminated in clinical settings. Spread of these genes may attribute to horizontal gene transfer of related entities.
