OBJECTIVE To provide reference for the rational use of antiemetic drugs in tumor chemotherapy patients. METHODS The data of tumor patients who were given antiemetic drugs were collected from 9 departments of our hospital with hospital information system from Oct. 1st to Nov. 30th in 2022， such as oncology department， radiotherapy department， gynecology department， and gastroenterology department. The application of chemotherapy drugs and the use of antiemetic drugs were analyzed statistically， and the irrational use of antiemetic drugs was analyzed. RESULTS A total of 520 patients were included， involving 248 （47.69%） using chemotherapy drugs with a moderate emetogenic risk level and 135 （25.96%） with a high emetogenic risk level. A total of 461 cases （73.06%） of 5-hydroxytryptamine 3-receptor antagonists were used， including palonosetron in 333 cases， ondansetron in 106 cases， tropisetron in 15 cases and granisetron in 7 cases， and only 148 cases of patients were prioritized for the use of nationally procured medicines and national essential medicines （32.10%）. Neurokinin-1 receptor antagonists were used in 170 cases （26.94%）， including fosaprepitant in 112 cases and aprepitant in 58 cases. The use of antiemetic drugs was unreasonable in 162 patients （31.15%）； among the types of irrational drugs， the antiemetic regimen was unreasonable in the largest number of cases （22.40%）， followed by the irrational pharmacoeconomics （19.13%）. CONCLUSIONS The emetogenic risk levels of chemotherapy drugs used for tumor patients in our hospital are primarily moderate to high， and there is irrational use of antiemetic regimen and pharmacoeconomics. Clinicians， nurses， pharmacists and hospital departments should collaborate as multiple teams to strengthen full supervision of the standardization of antiemetic drugs， reasonably select antiemetic drugs based on emetogenicity rating， and improve the compliance of doctors with the guidelines to ensure the safety， effectiveness， and cost-effective of patient medication.

At present,there are many difficulties in the diagnosis and treatment of acute vestibular syndrome(AVS).For example,complex and difficult identification of the cause of disease,uneven diagnosis and treatment levels of clinical doctors,weak humanistic care awareness,lack of communication skills,intrinsic affinity and other reasons,which make it difficult for AVS patients in the process of diagnosis and treatment,and cannot receive timely and effective treatment,resulting in an exacerbation of doctor-patient conflicts.Therefore,it is recommended to explore new paths of AVS diagnosis and treatment work using the humanistic care concept,respect each other between doctors and patients,build a team of medical staff with the value orientation of"humanistic care",and promote the organic unity of theory and practice of"humanistic care",with a view to better promoting the implementation of AVS diagnosis and treatment work,helping more patients rebuild confidence,enhancing quality of life,and improving the doctor-patient relationship.

Objective:To reveal the effect of β-sitosterol on cerebral ischemia-reperfusion injury (CIRI) in rats and whether its mechanism is related to endoplasmic reticulum stress (ERS).Methods:Fifty-three CIRI rats (CIRI models established by modified Longa method) were randomly divided into model group ( n=14), β-sitosterol low-dose group ( n=13), β-sitosterol medium-dose group ( n=13) and β-sitosterol high-dose group ( n=13); 12 rats underwent the same operation without blocking the middle cerebral artery were selected as sham-operated group. Rats in the sham-operated group and model group were given intragastric administration of 1 mL 5 g/L sodium carboxymethyl cellulose daily. Rats in the β-sitosterol low-dose group, β-sitosterol medium-dose group and β-sitosterol high-dose group were given intragastric administration of 1 mL β-sitosterol at 10, 20 and 40 mg/kg/d (dissolved in 5 g/L sodium carboxymethyl cellulose), respectively, for 14 consecutive d. Neurological function was evaluated according to Zea Longa 5 method. Rats were sacrificed and brain tissues were collected. Volume of cerebral infarction was measured by 2,3,5-triphenyl tetrazolium chloride (TTC) staining. Brain injury and neuronal apoptosis were evaluated by HE staining, Nissl staining and TUNEL. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) contents were detected by water-soluble tetrazolium 1 (WST-1) method, colorimetric method or thiobarbituric acid (TBA) method, respectively. The mRNA and protein expression levels of protein kinase R-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme-1 (IRE-1), activated transcription factor-6 (ATF-6), glucose-regulated protein 78 (GRP78), C/EBP homologous protein (CHOP) and Caspase-12 in the brain tissues were detected by qRT-PCR or Western blotting. Results:Compared with the sham-operated group, the model group had significantly increased neurological function score, cerebral infarction volume and TUNEL positive rate, decreased SOD and GSH-Px content, increased MDA content, and increased mRNA and protein expressions of PERK, IRE-1, ATF-6, GRP78, CHOP and Caspase-12 ( P<0.05). Compared with the model group, the β-sitosterol low-dose group, β-sitosterol medium-dose group and β-sitosterol high-dose group had significantly decreased neurological function score, cerebral infarction volume, and TUNEL positive rate, increased SOD and GSH-Px content, and decreased MDA content ( P<0.05); the β-sitosterol low-dose group, β-sitosterol medium-dose group and β-sitosterol high-dose group had significantly decreased mRNA and protein PERK expressions (mRNA: 2.17±0.17, 1.79±0.07 and 1.33±0.07; protein: 5.11±0.52, 2.91±0.26 and 1.98±0.17), IRE-1 expressions (mRNA: 1.75±0.18, 1.65±0.08 and 1.32±0.08; protein: 5.00±0.31, 4.05±0.27 and 1.98±0.14), ATF-6 expressions (mRNA: 2.24±0.12, 1.77±0.14 and 1.37±0.13; protein: 4.93±0.45, 4.04±0.30 and 3.10±0.20), GRP78 expressions (mRNA: 2.67±0.16, 2.11±0.16 and 1.69±0.11; protein: 5.02±0.38, 2.97±0.26 and 2.05±0.22), CHOP expressions (mRNA: 2.01±0.16, 1.70±0.19 and 1.40±0.10; protein: 4.92±0.39, 4.02±0.27 and 3.08±0.22) and Caspase-12 expressions (mRNA: 1.85±0.09, 1.61±0.09 and 1.30±0.09; protein: 3.03±0.20, 2.19±0.11 and 1.82±0.11) compared with the model group (mRNA: 2.99±0.28, 2.27±0.12, 2.57±0.21, 3.46±0.20, 2.50±0.23 and 2.35±0.16; protein: 6.98±0.48, 6.03±0.58, 5.98±0.63, 7.10±0.45, 6.00±0.53 and 5.02±0.43, P<0.05). Conclusion:β-sitosterol attenuates CIRI in rats, whose mechanism may be related to inhibition of ERS signal pathway.

To improve overall satisfaction of patients with the hospital and build a harmonious doctor-patient relationship, a survey on satisfaction of patients with ECG examination was conducted in a tertiary A hospital. The analysis was carried out from the aspects of inspection environment, inspection process, inspection experience and overall satisfaction. Logistic regression model was used to analyze the effect of various variables on satisfaction. This paper found that the overall satisfaction rate of patients with ECG examination was 85.18%, lower than that of outpatients. Patients with different characteristics had different satisfaction degree with ECG examination. Patient satisfaction was lower on Mondays and Wednesdays than that on other inspection days, and was lower between 10 a.m. and 14 p.m. The longer the waiting time, the lower satisfaction degree of patients with examination. Based on the results, hospitals should improve the construction of humanistic soft environment to improve the medical environment, scientifically plan the medical treatment process of ECG examination, and further strengthen doctor-patient communication. The ECG room should further promote its management level and strengthen its cultural construction.

Objective:To evaluate the treatment effect of hemoperfusion(HP) on Henoch-Sch?nlein purpura(HSP) outcomes.Methods:PubMed, Cochrane library, Web of science, Wanfang database, CNKI and CBM database were searched from inception to February 2020.Literatures of randomized controlled trials(RCTs) that investigated the effect of HP on HSP outcomes were included.Articles screening, data extraction and quality assessment were accomplished by two investigators independently, and statistical analyses were performed by RevMan 5.3.Results:Thirteen RCTs were included with 803 cases, of which, 397 cases were in the HP group while 406 cases were in the control group.The Meta-analysis revealed the HP group had less disappearing time of hematuresis or albuminuria[ MD=-2.77, 95% CI(-3.18, -2.36), P<0.001], relieving time of abdominal pain[ MD=-1.70, 95% CI(-2.17, -1.23), P<0.001], disappearing time of hematochezia[ MD=-1.54, 95% CI(-1.68, -1.40), P<0.001], and the length of hospital stay[ MD=-3.23, 95% CI(-3.60, -2.87), P<0.001] than the control group. Conclusion:The HP could shorten disappearing time of hematuresis or albuminuria, relieving time of abdominal pain, disappearing time of hematochezia, and the length of hospital stay of HSP.

Myxomas are the most frequent, cardiac benign cardiac tumors which often present with stroke caused by tumorous orthrombotic emboli. The treatment of embolic stroke due to cardiac myxoma is still a clinical and technical challenge. A 61-year-old man who had an embolic stroke in the left middle cerebral artery was admitted to the Third Poeple′s Hospital of Huizhou. The initial National Institutes of Health Stroke Scale (NIHSS) score was 16. He received endovascular thrombectomy after intravenous recombinant tissue plasminogen activator (rt-PA) one hour after stroke onset. No intracranial hemorrhage developed. Pathological study of embolus showed a myxoma. A cardiac mass was found in the left atrium and removed surgically three weeks after stroke. Pathological study of the tumor showed a myxoma. At the one-month follow-up after excision of myxoma, the NIHSS score was 1 and the modified Rankin scale score was 0. No recurrence of embolism occurred after surgical resection. Endovascular thrombectomy after intravenous rt-PA (bridging therapy) for embolic stroke due to cardiac myxoma is safe and effective, and early resection of atrial myxoma can effectively avoid recurrence of cerebral infarction.

Objective To investigate the effectiveness and safety of intravenous thrombolytic therapy with low-dose alteplase for elderly patients with acute ischemic stroke.Methods The elderly patients with acute ischemic stroke were enrolled prospectively (onset within 4.5 h,aged ≥75 years).They were randomly divided into either a low-dose group (0.6 mg/kg) or a standard-dose group (0.9 mg/kg).The primary outcome was the modified Rankin Scale (mRS) score determined the good outcome (mRS score 0-2) and poor outcome (mRS score ＞2) at 90 d after treatment;the secondary outcome was intracranial hemorrhage and symptomatic intracranial hemorrhage at 24 h after thrombolysis,and death within 90 d.Results A total of 65 elderly patients with acute ischemic stroke were enrolled,including 32 in the low-dose group and 33 in the standard-dose group.There were no significant differences in all baseline clinical data between the two groups.Compared with before treatment,the proportions of patients with the mRS score 0-2 were significantly higher in both groups at 7 d,14 d,and 90 d after treatment,but there were no significant differences in good outcome rate at the same time point after treatment between the two groups.In addition,there were no significant differences in intracranial hemorrhage (36.4％ vs.25.0％;x2 =0.985,P =0.321),symptomatic intracerebral hemorrhage (21.2％ vs.9.4％;x2 =1.749,P =0.186) at 24 h after treatment,and incidence of death within 90 d after treatment (12.1％ vs.6.3％;x2 =0.151,P=0.697)between the two groups.Conclusions The effectiveness and safety of intravenous thrombolytic therapy with low-dose alteplase (0.6 mg/kg) in elderly patients with acute ischemic stroke is equivalent to the standard dose.

Objective To construct the core competency evaluation scale for nurses in Department of Cardiology, and evaluate its psychometric characteristics. Methods The core competency evaluation scale for nurses in Department of Cardiology was developed by literatures review and clinical situation. A total of 176 nurses in 5 class Ⅲ grade A hospitals in Shaanxi Province were selected by convenient sampling method and investigated anonymously. Results The choice rates of all alternatives were lower than 80%. One item was deleted because its coefficient of variation was less than 20%. Discrimination correlation coefficients were between 0.340 - 0.732. The content validity index was 0.928. Five factors were extracted by exploratory factor analysis, with the cumulative contribution of 67.6%. Five factors were expected. The factor analysis confirmatory showed that χ2/df=4.013, SRMR=0.051, RMSEA=0.062. The split half reliability was 0.842; Cronbach's alpha was 0.856, and the retest reliability was 0.908. Conclusions The core competency evaluation scale for nurses in department of cardiology has good validity and reliability which can be used to evaluate the core competency.

BACKGROUNDPatellofemoral osteoarthritis commonly occurs in older people, often resulting in anterior knee pain and severely reduced quality of life. The aim was to examine the effectiveness of arthroscopic patelloplasty and circumpatellar denervation for the treatment of patellofemoral osteoarthritis (PFOA).

METHODSA total of 156 PFOA patients (62 males, 94 females; ages 45-81 years, mean 66 years) treated in our department between September 2012 and March 2013 were involved in this study. Clinical manifestations included recurrent swelling and pain in the knee joint and aggravated pain upon ascending/descending stairs, squatting down, or standing up. PFOA was treated with arthroscopic patelloplasty and circumpatellar denervation. The therapeutic effects before and after surgery were statistically evaluated using Lysholm and Kujala scores. The therapeutic effects were graded by classification of the degree of cartilage defect.

RESULTSA total of 149 cases were successfully followed up for 14.8 months, on average. The incisions healed well, and no complications occurred. After surgery, the average Lysholm score improved from 73.29 to 80.93, and the average Kujala score improved from 68.34 to 76.48. This procedure was highly effective for patients with cartilage defects I-III but not for patients with cartilage defect IV.

CONCLUSIONSFor PFOA patients, this procedure is effective for significantly relieving anterior knee pain, improving knee joint function and quality of life, and deferring arthritic progression.
