Objective:To investigate which indicator is more advantageous when using arterial oxygen saturation(SaO2)and fingertip pulse oxygen saturation(SpO2)for blood oxygen detection in patients with hyperleukocytic acute leukemia(HAL).Methods:In this prospective research,the difference between SaO2 and SpO2 of 18 HAL patients(observation group)and 14 patients(control group),as well as the relationship between the difference and white blood cell(WBC)counts were analyzed.Results:SaO2 was lower than SpO2 in the observation group(P＜0.05),and SpO2-SaO2 difference was positively correlated with WBC counts(r=0.47).However,there was no statistical difference between SaO2 and SpO2 in the control group.SaO2 and PO2 showed a downward trend with the prolongation of detection time after arterial blood was collected in the observation group,but there was no statistical difference.There was no downward trend of SaO2 and PO2 in the control group.Conclusion:HAL patients have a phenomenon where SaO2 is lower than SpO2,that is pseudohypoxemia,and this phenomenon may be caused by excessive consumption of oxygen by the leukemia cells in vitro.SpO2 can be monitored bedside in real time and is non-invasive,it is a better way to detect the blood oxygen status of HAL patients.

Objective To explore the incidence and risk factors of perioperative ischemic stroke in non-cardiac and non-neurosurgical surgeries and its correlation with preoperative risk assessment of cerebrovascular events,so as to guide perioperative risk management.Methods A retrospective study was conducted on 40 patients aged≥18 years who underwent non-cardiac and non-neurosurgical surgeries and experienced perioperative ischemic stroke in the First Affiliated Hospital of Henan University of Science and Technology from January 2015 to January 2022,forming the stroke group.A control group of 160 patients without perioperative ischemic stroke was selected in a 1:4 case-control ratio,matched for gender,age,date of operation,and the surgeon.Clinical data and preoperative risk assessment of cerebrovascular events(including the single or combined application of head CT/MRI,transcranial Doppler ultrasound,carotid ultrasound,and neurological consultation)of the two groups of patients were collected and statistically analyzed.Multiple logistic regression analysis was used to identify risk factors associated with perioperative ischemic stroke.Results The incidence of perioperative ischemic stroke was 0.042%.Multiple logistic analysis results showed that hypertension(OR=7.858,95%CI 2.175-28.388,P=0.002),hyperlipidemia(OR=4.457,95%CI 1.320-15.049,P=0.016),renal insufficiency(OR=8.277,95%CI 1.480-46.282,P=0.016),and intraoperative hypotension(OR=3.862,95%CI 1.211-12.317,P=0.022)were independent risk factors for perioperative ischemic stroke in non-cardiac and non-neurological surgeries;preoperative cerebrovascular risk assessment(OR=0.130,95%CI 0.031-0.542,P=0.005)was a protective factor against it.Conclusions The incidence of perioperative ischemic stroke in non-cardiac and non-neurosurgical surgery is low but has a poor prognosis.Hypertension,hyperlipidemia,renal insufficiency,and postoperative hypotension are risk factors for perioperative ischemic stroke,while preoperative cerebrovascular event risk assessment is beneficial to reducing its incidence.

AIM To investigate the effects of aloperine on the pulmonary expressions of TREM-1 and TREM-2 in septic rats.METHODS The rats were randomly divided into the control group,the model group and the low,medium and high dose aloperine groups ( 25,50 and 100 mg/kg ).The corresponding intraperitoneal aloperine injection was administered 0.5 h before modeling,and the rats'Penh,Cdyn and EF50 were detected 24 hrs after modeling.The rats had their pathological injury of the lung tissue observed by HE staining;their pulmonary mRNA expressions of TREM-1,TREM-2,TNF-α,IL-1β and IL-10 detected by RT-qPCR method;and their pulmonary protein expressions of TREM-1,TREM-2,TNF-α,IL-1β,IL-10,p-p65,p-PI3K and p-Akt detected by Western blot.RESULTS Compared with the control group,the model group displayed increased Penh (P<0.01),decreased Cdyn and EF50 ( P<0.01);destroyed lung tissue structure and thickened alveolar septum,increased mRNA and protein expressions of TREM-1,TNF-αand IL-1β( P<0.05,P<0.01);decreased mRNA and protein expressions of TREM-2 and IL-10 ( P<0.05,P<0.01);and increased protein expressions of p-p65,p-PI3K and p-Akt (P<0.01).Compared with the model group,the aloperine groups shared decreased Penh ( P<0.01);increased Cdyn and EF50 ( P<0.01);improved pulmonary structure and thinner alveolar wall,decreased mRNA and protein expressions of TREM-1,TNF-α and IL-1β( P<0.05,P<0.01 );increased mRNA and protein expressions of TREM-2 and IL-10 ( P<0.05,P<0.01);and decreased protein expressions of p-p65,p-PI3K and p-Akt (P<0.05,P<0.01).CONCLUSION Aloperine can alleviate the inflammatory response of septic rats by down-regulating TREM-1 expression and up-regulating TREM-2 expression,which may be related to the inhibited activation of PI3K signaling pathway.

Coronary heart disease (CHD) and stroke are the most well-known cardiovascular diseases, which share many common pathological basis. Yindan Xinnaotong soft capsule (YDXNT) is a commonly used Chinese patent medicine in the treatment of stroke and CHD. However, its action of mechanism of co-treatment for stroke and CHD is still unclear. The aim of this study was to explore the common mechanism of YDXNT in co-treatment of CHD and stroke using network pharmacology, experimental verification and molecular docking. An integrated literature mining and databases of IPA, ETCM, HERB, Swiss Target Prediction, OMIM and GeneCards were used to screen and predict active ingredients and potential targets of YDXNT in co-treatment of CHD and stroke. The protein-protein interaction network, GO analysis and pathway analysis were analyzed by IPA software. The effect of YDXNT on core targets was verified by immunofluorescence. UPLC-QTOF/MS and molecular docking were used to screen and predict the main active constituents of YDXNT and their interactions with core targets. A total of 151 potential targets are predicted for YDXNT in co-treatment of CHD and stroke. Hypoxia-inducible factor-1α (HIF1α)-matrix metalloproteinase-9 (MMP9)-mediated HIF1α signaling pathway serves as one of the common mechanisms. YDXNT could reduce the increase of mitochondrial fluorescence intensity and the protein expression of HIF1α and MMP9 in HL-1 and HA induced by oxygen and glucose deprivation/reperfusion (OGD/R) in a dose-dependent manner. Baicalin may be the material basis for treating stroke and CHD with YDXNT. In conclusion, the HIF1α signaling pathway is one of the common key mechanisms of YDXNT in the co-treatment of stroke and CHD. The study provides support and basis for the in-depth scientific connotation of the traditional Chinese medicine theory of "same treatment to different diseases".

Four new sesquiterpene quinone meroterpenoids, dysideanones F-G (1-2) and dysiherbols D-E (3-4), were isolated from the marine sponge Dysidea avara collected from the South China Sea. The new structures were elucidated by extensive analysis of spectroscopic data including HR-MS and 1D and 2D NMR spectra, and their absolute configurations were assigned by single-crystal X-ray diffraction and ECD calculations. Anti-inflammatory evaluation showed that dysiherbols D-E (3-4) exhibited moderate inhibitory activity on TNF-α-induced NF-κB activation in human HEK-293T cells with IC₅₀ values of 10.2 and 8.6 μmol·L^-1, respectively.

Objective:To translate the Empathy for Pain Scale (EPS) and evaluate the reliability and validity of the Chinese version of EPS in medical students.Methods:The items of the Chinese version of EPS were determined by translation, back-translation, semantic analysis, expert consultation and culture adaptation. From June to October 2018, this study selected 531 undergraduate students by convenience sampling to carry out questionnaire survey. Correlation analysis and critical ratio were used to the item analysis. Validity test was implemented with the content validity, construct validity and criterion-related validity; and internal consistency was tested with the Cronbach's α value and split-half reliability.Results:The Chinese version of EPS had 12 items and two factors named as the body and mind discomfort reactions and empathy reactions with 69.059% for the total variance contribution. Content validity of items ranged from 0.83 to 1.00, and the total content validity was 0.94. The total score of the Chinese version of EPS had a positive correlation with the score of the interpersonal reactivity index (IRI-C) ( r=0.370, P< 0.01) . The Cronbach's α value of the scale was 0.914; Cronbach's α values of two dimensions, the body and mind discomfort reactions and empathy reactions, were 0.935 and 0.775 respectively. The split-half reliability of the scale was 0.896. Conclusions:The Chinese version of EPS has four scenes and two dimensions as well as a good reliability and validity which could be used to evaluate the level of empathy for pain among medical students in China.

To systemically evaluate the efficacy and safety of Jintiange Capsules in the treatment of postmenopausal osteoporosis(PMOP).Seven literature databases were retrieved systematically,and two reviewers independently searched and screened studies,extracted data,and included all the randomized controlled trials on Jintiange Capsules in the treatment of PMOP.Interventions included comparison of Jintiange Capsules with placebo and routine treatment,and the studies on Jintiange Capsules combined with routine treatment versus conventional treatment were also included.The evaluation indicators of the study included at least one of the followings:fracture,quality of life,daily living ability,clinical symptoms,death,adverse events/adverse reactions,bone density,and bone metabolism indexes.The original study quality evaluation was conducted by following the Cochrane Handbook standard and statistical analysis was performed by using Rev Man 5.2.A total of 7 randomized controlled trials were included and the study quality was low.Meta-analysis showed that as compared with conventional treatment alone,Jintiange Capsules combined with conventional treatment showed more obvious effects in pain relief(MD=-0.98,95% CI[-1.55,-0.41],P=0.000 8),increasing blood calcium levels(MD=0.05,95% CI[0.02,0.09],P=0.003) and lowering serum alkaline phosphatase levels(MD=-12.92,95% CI[-24.09,-1.75],P=0.02).In addition,the Chinese patent medicine alone or in combination with conventional treatment was relatively safe.In conclusion,Jintiange Capsules has a certain effect in treating PMOP,but the quality of evidence is low.It is necessary to conduct well designed randomized controlled trials and select recognized evaluation indicators,especially the end outcomes in order to further improve the clinical evidence.

OBJECTIVE: To investigate the clinical features of acute myeloid leukemia patients aged over 80 years. METHODS: The clinical data from 24 cases of acute myeloid leukemia (non-M3) aged over 80 years were analyzed retrospectively. Clinical characteristics, therapeutic efficacy and overall survival rate of the patients received low dose chemotherapy and/or decitabine were compared with that received only supportive care. RESULTS: According to FAB classification, the 10 patients were M2 subtypes (41.7%), the 7 patients were M4 subtypes (29.2%), the 4 patiens were M5 (16.7%), the 3 patients were unclassifed (16.5%). 22 patients (91.0%) were complicated with underling diseases. Among 13 patients received low dose chemotherapy or decitabine, 8 cases (61.5%) achived partial remission or higher remission. The median survival time of patients who reseived chemotherapy was 30 weeks, and signicantly longer than that of patients received supportive care (median survival time was 9 weeks (P<0.05)). The univariated analysis showed that WBC≥50×10/L, ECOG≥2 and received supportive care were unfavonrable prognostic factors for overall survival. CONCLUSION More than half of patients aged over 80 years who received individudized treatment can achieve partial remission or higher remission, and can have more longer survival time..
