Objective:To investigate the effects of Kanglaite injection combined with chemotherapy on quality of life and myelosuppression in patients with non-small cell lung cancer (NSCLC).Methods:The clinical data of 60 patients with NSCLC who received treatment at Zhejiang Jinhua Guangfu Tumor Hospital from August 2018 to February 2022 were retrospectively analyzed. These patients were divided into an experimental group and a control group, with 30 patients in each group according to the treatment methods used. The patients in the experimental group received the Kanglaite injection in combination with chemotherapy using gemcitabine and cisplatin, whereas the patients in the control group were treated solely with chemotherapy with gemcitabine and cisplatin. The quality of life was evaluated using the Karnofsky Performance Status score. Before and after treatment, a comparison was made between the two groups in terms of Karnofsky Performance Status score, the incidence of adverse reactions (such as myelosuppression), and clinical efficacy.Results:After treatment, the disease control rate and objective response rate in the experimental group were 86.67% (26/30) and 60.00% (18/30), respectively, which were significantly higher than 60.00% (18/30) and 30.00% (9/30) in the control group ( χ2 = 4.18, 4.31, both P < 0.05). Prior to treatment, the Karnofsky Performance Status scores in the experimental and control groups were (70.68 ± 3.75) points and (70.29 ± 5.11) points ( t = 0.34, P = 0.790), respectively. After treatment, the Karnofsky Performance Status scores in the experimental group were significantly higher than those in the control group [(67.02 ± 5.87) points vs. (62.37 ± 3.59) points, t = -5.29, P < 0.05]. The incidence of adverse reactions in the experimental group was significantly higher than that in the control group [40.00% (12/30) vs. 36.67% (11/30), χ2 = 0.07, P = 0.790). Additionally, the incidence of myelosuppression in the experimental group was significantly lower than that in the control group [56.67% (17/30) vs. 86.67% (26/30), χ2 = 6.90, P = 0.030]. Conclusion:Compared with chemotherapy alone, Kanglaite injection combined with chemotherapy can effectively relieve the clinical symptoms of patients with advanced non-small cell lung cancer, leading to improved prognosis.

Objective To investigate the factors affecting the early phase insulin secretion function in type 2 diabetes patients and guide the clinical improvement of islet function.Methods A total of 137 patients with type 2 diabetes mellitus were selected to undergo glucose tolerance test to determine multipoint blood glucose and C-peptide.According to the level of early insulin secretion index(IGI),secretion is divided into low IGI group,medium IGI group and high IGI group.Univariate and multivariate Logistic regression analysis was performed.Results Body mass index,fasting C-peptide,uric acid,triglyceride,steady-state model[3 cell secretion index and fatty liver in high IGI group were higher than those in low IGI group(P＜0.05).The 120-minute glucose and HBA1c in high IGI group were lower than those in low IGI group(P＜0.05).Body mass index,fasting C-peptide and fatty liver in medium IGI group were higher than those in low IGI group(P＜0.05).The 120-minute glucose and HBA1c in medium IGI group were higher than those in low IGI group(P＜0.05).Multi variate Logistic regression showed that glycosylated hemoglobin(OR=0.796,95％CI:0.676-0.938,P＜0.05)was an independent risk factor for IGI30,and the steady-state insulin resistance index(OR=3.161,95％CI:1.324-7.553,P＜0.05),triglyceride(OR=1.287,95％CI:1.005-1.650,P＜0.05)is a protective risk factor for IGI30.Conclusion Glycosylated hemoglobin is a risk factor for the secretion of pancreatic islet in early stage of type 2 diabetes mellitus.Insulin resistance is a protective factor for the secretion of early phase insulin function.

Objective To compare the differences in the levels of lactate dehydrogenase(LDH),creatine kinase(CK),and neuron-specific enolase(NSE)in the cerebrospinal fluid(CSF)between the patients with purulent meningitis(PM)and those with tuberculous meningitis(TBM)and evaluate the utility of the three biomarkers in the differentiation of PM and TBM.Methods Thirty-five PM patients and 45 TBM patients who attended the Department of Neurology from December 2019 to December 2021 were enrolled in this study.The CSF samples were collected from the patients before treatment.The levels of LDH,CK,NSE,and glucose,protein,and chloride in CSF were measured and compared between PM and TBM patients.The correlation between the biomarkers in CSF was analyzed by Pearson correlation coefficient.Linear regression analysis was performed to analyze the risk factors for the occurrence of TBM.Receiver operating characteristic(ROC)curves were plotted to evaluate the discriminative value of CSF LDH,CK,NSE alone or in combination in differential diagnosis of PM and TBM.Results Patient age,gender,clinical features such as fever,pathological signs,vomiting,limb twitching,and CSF levels of glucose and protein did not show significant difference between TBM patients and PM patients(P＞0.05).TBM was associated with significantly higher LDH and NSE levels in CSF and significantly lower CK level and chloride in CSF compared to PM(P＜0.05).Pearson correlation analysis showed that LDH level in CSF was negatively correlated with CK and chloride(r＜0,P＜0.05),and positively correlated with NSE(r＞0,P＜0.05).CK was negatively correlated with NSE(r＜0,P＜0.05),and positively correlated with chloride(r＞0,P＜0.05).NSE was negatively correlated with chloride(r＜0,P＜0.05).Linear regression analysis showed that LDH,CK,NSE,and chloride levels in CSF were all associated with the occurrence of TBM(P＜0.05).ROC curves demonstrated that the AUCs of CSF levels of LDH,CK,NSE alone and in combination for differentiation between PM and TBM were 0.849(95％CI:0.768-0.930),0.858(95％CI:0.779-0.937),0.851(95％CI:0.771-0.931),and 0.954(95％CI:0.911-0.996),respectively.Conclusions The clinical features are similar for PM and TBM patients.However,the levels of LDH,CK,and NSE in CSF are different between PM and TBM.LDH,CK,NSE in combination may improve the differential diagnosis between PM and TBM.

Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Objective:To investigate the ultrasonographic features and genetic etiology of complex talipes equinovarus (TE) in fetuses.Methods:This retrospective study enrolled 95 cases of complex TE (TE complicated by other abnormalities) who were diagnosed by prenatal ultrasound in the Third Affiliated Hospital of Zhengzhou University from March 2018 to December 2022. Chromosome karyotype analysis and/or chromosomal microarray analysis (CMA) [or copy number variation-sequencing (CNV-seq)] were performed on all cases for prenatal genetic diagnosis and those with normal results were further tested by whole exome sequencing (WES). Prenatal ultrasonographic and genetic features of complex TE in fetuses were summarized. Complicated abnormalities in the fetuses were classified into nine categories according to the involved system or site and based on each category these subjects were divided into with or without the corresponding complicated abnormalities groups. Besides, these cases were also divided into single-system and multi-system abnormality groups based on the number of involved systems or sites of complicated abnormalities. The detection rates of WES abnormality (pathogenic or likely pathogenic variants) and the overall detection rate of genetic abnormality [karyotype abnormality detected by chromosome karyotype analysis, pathogenic or likely pathogenic copy number variations (CNVs) detected by CMA (or CNV-seq), and pathogenic or likely pathogenic variation detected by WES] were compared between different groups using Chi-square test or Fisher's exact test. Results:Abnormal chromosome karyotypes were identified in 10 (24.4%) of 41 cases receiving chromosome karyotype analysis, pathogenic and likely pathogenic CNVs were found in seven (7.6%) of 92 cases by CMA (or CNV-seq). WES was performed on 37 cases with negative results of chromosomal karyotype analysis and CMA (or CNV-seq) and the detection rate of pathogenic and likely pathogenic variants was 43.2% (16/37). The detection rate of WES abnormality was higher in the fetuses with musculoskeletal abnormalities than in those without the abnormalities [71.4% (15/21) vs. 1/16, Fisher's exact test, P<0.001], while in those with other postural abnormalities was higher than that in the group without other postural abnormalities [12/16 vs. 19.0% (4/21), Fisher's exact test, P=0.001]. The genetic causes of complex TE were identified in 34.7% (33/95) of the fetuses by the sequential genetic diagnosis using chromosome karyotype analysis, CMA (or CNV-seq), and WES. The overall detection rate of genetic abnormality was higher in the group with multi-system abnormality than in the group with single-system abnormality [48.9% (22/45) vs. 22.0% (11/50), χ2=7.55, P=0.006], in the group with musculoskeletal system abnormalities and without [46.8% (22/47) vs. 22.9% (11/48), χ2=5.98, P=0.014], and in the group with other postural abnormality and without [47.2% (17/36) vs. 27.1% (16/59), χ2=3.99, P=0.046]. Nine cases that were considered isolated TE on initial ultrasound were corrected to a complex diagnosis on subsequent ultrasound examinations. Of all the involved system or site, the neurologic abnormalities were the most diverse (13 kinds) and had a diversity of ultrasound presentations. Conclusions:Genetic diagnosis should be performed when prenatal ultrasound suggests fetal complex TE. WES is conducive to improving the prenatal detection rate of monogenic diseases, especially in fetuses complicated by musculoskeletal abnormalities. Isolated TE fetuses require serial ultrasound examinations to correct the diagnosis in time and genetic testing should be performed if necessary. Additional attention should be paid to the TE fetus for comorbid neurologic abnormalities at the time of ultrasonography to rule out TE as an intrauterine harbinger of neuromuscular disease.

Objective:To investigate the predictive value of YKL-40 at admission on stroke-associated pneumonia (SAP) and poor outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to Taixing People’s Hospital from February 2020 to March 2021 were enrolled prospectively. The poor outcome was defined as 3-6 points on the modified Rankin Scale at 90 d after onset. Multivariate logistic regression analysis was used to determine the independent predictors of SAP and poor outcome, and the predictive value of serum YKL-40 on SAP and poor outcome was evaluated by receiver operating characteristic (ROC) curve. Results:A total of 377 patients with AIS were enrolled. The median serum YKL-40 was 127.16 μg/L. One hundred and four patients (27.6%) had SAP, and 126 (33.4%) had poor outcomes at 90 d after onset. Multivariate logistic regression analysis showed that after adjusting for confounding factors, YKL-40 was the independent predictors of SAP (odds ratio [ OR] 1.005, 95% confidence interval [ CI] 1.003-1.008; P=0.001) and poor outcome at 90 d ( OR 1.009, 95% CI 1.006-1.011; P=0.001). The ROC curve analysis showed that the area under the curve of YKL-40 for predicting SAP was 0.769 (95% CI 0.713-0.824; P<0.001), the best cutoff value was 168.70 μg/L, and the sensitivity and specificity were 71.2% and 75.1% respectively; the area under the curve of YKL-40 for predicting poor outcome at 90 d was 0.787 (95% CI 0.735-0.840; P<0.001), the best cutoff value was 195.56 μg/L, and the sensitivity and specificity were 68.3% and 84.1% respectively. Conclusion:Higher serum YKL-40 at admission has a good predictive value for SAP and poor outcome at 90 d in patients with AIS.

Objective: To test the reliability and validity of the Chinese version of the Handoff Clinical Examination Exercise (Handoff CEX). Methods: The Chinese version of the Handoff CEX was composed of two parts, one to assess the nurse providing the handoff and another to assess the nurse receiving the handoff. A total of 80 handoffs was evaluated to test the reliability and validity of the Chinese version of the Handoff CEX. Results: A total of 320 evaluations of handoff was obtained. The Cronbach α coefficient was 0.85 for the handoff provider, and that was 0.80 for the handoff recipient. Weighted kappa scores for provider evaluations ranged from 0.31-0.52, and that for recipient evaluations ranged from 0.35-0.55. The correlation coefficients between each factor ranged from 0.23 to 0.62, and that between each factor and the total scale ranged from 0.33 to 0.64 (P<0.05). Experienced nurses (>5 years) received significantly higher mean scores than inexperienced nurses(≤5 years) in all domains except organizational efficiency and professionalism(P<0.05). Conclusion The Chinese version of the Handoff CEX is a reliable and valid tool to assess the nursing handoff, which is useful for educators, supervisors and clinical nurses to provide training, ongoing assessment and feedback to improve the quality of handoff.

Ovarian cancer is the second deadliest gynecological malignancy around the world. The survival rate is closely related to the tumor stage and treatment. Radionuclide imaging, as a functional imaging at the molecular level, can provide a non-invasive method for in-depth understanding of pathophysiological process, which is important for the diagnosis and treatment of ovarian cancer. Nuclear imaging of malignant tumors has become a hot and important research topic in basic and clinical research. This review summarizes the current process in nuclear imaging of ovarian cancer, including glucose metabolism, cell proliferation, cellular receptors/proteins, and immune molecule imaging.

Objective: To explore the clinical and laboratory characteristics and therapeutic effect of acute promyelocytic leukemia (APL) with t(2;17;15). Methods: The G-banding technique was used for karyotypic analysis in a female patient with APL who was admitted to the First Affiliated Hospital of Zhengzhou University in December 2018. PML-RARα fusion gene was quickly detected by fluorescence in situ hybridization (FISH). The real-time quantitative polymerase chain reaction (RT-PCR) was used to detection 43 kinds of fusion gene, and the gene mutations were detected by next generation sequencing (NGS). The induction therapy was given with oral retinoic acid+ intravenous infusion of arsenic trioxide, followed by 3 courses of retinoic acid+ arsenic trioxide consolidation therapy. Results: The G-banding karyotypic analysis demonstrated 46, XX, t(2;17;15) (q31;q21;q22)[8]/46, XX[2]. FISH results indicated that 62.0% of analyzed cells were positive for the PML-RARα fusion gene. RT-PCR further revealed the positive PML-RARα fusion gene transcript. NGS detection of gene mutations showed no obvious abnormalities. After 39 days of induction therapy with retinoic acid and arsenic trioxide, the patient achieved complete remission (CR). The karyotype was 46XX[20], and PML-RARα/ABL was 0/100. Then, the patient was treated with 3 courses of consolidation therapy, and the results remained in CR. Conclusions APL with complex t(2;17;15) (q31;q21;q22) is rare, and the morphological characteristics are not typical, but it is still associated with the formation of PML-RARα fusion gene. Retinoic acid+ arsenic trioxide has a good therapeutic effect, and the long-term efficacy still needs follow-up.

Objective: To identify the impeding and promoting factors of role definition in nursing handoff, in order to increase the quality of nursing handoff. Methods: Two nursing managers, 22 head nurses and four nurses were recruited by purpose sampling. Data were collected by using focus group study, and analyzed using content analysis. Results: According to the framework of role transition theory, the factors could be classified as individual factors (37 items, 23.72%), organizational factors (105 items, 67.31%), effectiveness of role definition (11 items, 7.05%), and problems of role definition (3 items, 1.92%). Conclusions Role definition in nursing handoff helping the coming nurse check the performance of the last shift and transfer the nursing responsibility, contributes to the improvement of nursing quality, but there are still many factors affecting the role definition in nursing handoff.
