BackgroundThere exist differences in the subjective and objective cognitive functions of patients with depressive disorder， ane there are limited research on influencing factors of such phenomenon currently. ObjectiveTo explore the differences in subjective and objective cognitive function in patients with depressive disorder as well as influencing factors， and to provide references for further understanding of cognitive impairment in patients with depressive disorder. MethodsA total of 77 patients with depressive disorder who received outpatient or inpatient treatment in the Fourth People's Hospital of Chengdu from January 13， 2022 to December 11， 2023 were selected for the study. These patients also met the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders， fifth edition（DSM-5）. Various tools were employed to assess patients in this study： Montgomery-Asberg Depression Rating Scale （MADRS） for the depressive symptoms， Perceived Deficits Questionnaire for Depression （PDQ-D） and Chinese Version of Brief Neurocognitive Test Battery （C-BCT） for the subjective and objective cognitive function， Sheehan Disability Scale （SDS） for the social function， and Clinical Global Impression-Severity of Illness（CGI-SI） for the severity of patient's condition. Pearson correlation analysis was used to examine the correlation of subjective and objective cognitive function and their differences with age， years of education， MADRS total score， SDS total score， and CGI-SI score. Multiple linear regression was used to explore the influencing factors of the differences between subjective and objective cognitive function. ResultsThere was a statistically significant difference in the total PDQ-D scores and the difference of subjective and objective cognitive function （D value） between depressive patients with and without medication （t=-4.228， -2.392， P<0.05 or 0.01）. There was no statistically significant correlation in subjective and objective cognitive function in patients with depressive disorder （r=-0.148， P>0.05）. Negative correlations can be observed between the PDQ-D total score and age or years of education （r=-0.333， -0.369， P<0.01）. The PDQ-D total score was positively correlated with MADRS total score， SDS total score and CGI-SI score （r=0.487， 0.637， 0.434， P<0.01）. D value was negatively correlated with age and years of education （r=-0.411， -0.362， P<0.01）， while positively correlated with MADRS total score， SDS total score and CGI-SI score （r=0.259， 0.468， 0.299， P<0.05 or 0.01）. Age （β=-0.328， P<0.01） and SDS total score （β=0.409， P<0.01） were two predictive factors for D value. ConclusionThe difference between subjective and objective cognitive function among patients with depressive disorder is related to several factors including age， years of education， severity of symptoms and impairment of social function. ［Funded by Surface Project of National Natural Science Foundation of China （number， 62173069）； Technological Innovation 2030-Major Project of "Brain Science and Brain-Like Research" （number， 2022ZD0211700）； Key R&D Support Program and Major Application Demonstration Project of Chengdu Science and Technology Bureau （number， 2022-YF09-00023-SN）］

Objective To investigate the equivalent conversion of head injury criterion(HIC)under anterior-posterior(AP)and lateral-medial(LM)craniocerebral impact for mild craniocerebral injury in rats using motor evoked potential(MEP)and β-amyloid precursor protein(β-APP)immunohistochemistry(IHC).Methods Sixty healthy adult male SD rats were randomly divided into 0 m control group,0.5 m-AP and 0.5 m-LM injury groups,and 1 m-AP and 1 m-LM injury groups(12 rats in each group).The control group did not undergo any impact injury experiment.After the impact injury experiment,the injury and control groups were subjected to excessive anesthesia to produce β-APP immunohistochemical stained slices,and the percentage of positive area and integral optical density(IOD)in the brainstem pyramidal tract area of the slices were determined.The MEP groups were divided in the same manner as the IHC groups and the MEP amplitudes of the MEP and control groups were measured after the impact injury experiment.Results With an increase in the degree of injury,the decrease in MEP amplitude,percentage of positive areas,and IOD in the injury groups significantly increased.When the degree of injury was low,the sensitivity of IHC was higher than that of MEP.When the degree of injury was the same,the HIC in the LM direction was lower than that in the AP direction.When the HIC was the same,the degree of injury in the LM direction was greater than that in the AP direction.Conclusions The joint evaluation of MEP and β-APP can provide experimental references for the study of HIC equivalent conversion in AP-LM craniocerebral impact injury.

Objective:To analyze the distribution of clinically isolated fungal strains and their resistance to common antifungal drugs in Shandong province.Methods:Through the Shandong Children’s Bacterial & Fungal Drug Resistance Surveillance and Research Collaborative Network, a total of 1 030 fungi were collected in 46 hospitals of Shandong province from January 1 to December 31, 2018. The source and type of strains were analyzed, and antifungal drug sensitivity tests were performed by using the micro-dilution method. Whonet 5.6 and SPSS 22.0 were applied to analyze the data.Results:The overall main strains were Candida albicans (38.74%, 399/1 030), Candida tropicalis (16.99%, 175/1 030) and Candida parapsilosis (16.41%, 169/1 030); the main fungi strains in child patients were C. albicans (52.50%, 63/120), C. parapsilosis (12.50%, 15/120) and C. tropicalis (9.17%, 11/120); the main fungi strains in adult patients were C. albicans (36.37%, 331/910), C. tropicalis (17.03%, 155/910) and C. parapsilosis (15.27%, 139/910). The isolation rate of main Candida strains from January to March and August to December was much higher than that of other months. The drug resistance rates of C. albicans to fluconazole and voriconazole were 7.14% and 7.43%, respectively, and the drug resistance rates to itraconazole were 50.44%. The resistance rates of C. tropicalis to fluconazole, voriconazole and itraconazole were 29.05%, 23.29% and 48.65%, respectively. The sensitivity rates of C. parapsilosi to fluconazole, voriconazole and itraconazole were 93.06%, 93.75% and 94.44%, respectively. Candida glabrata showed a dose-dependent sensitivity rate of 2.33% to fluconazole. Analysis of 244 blood fungi strains showed that non-candida albicans bacteremia accounted for 70.08%. In the pathogen spectrum covering 92.22%, fluconazole was sensitive to 64.65% of the pathogens, voriconazole was 68.88%, and amphotericin B was 88.75%. After quantification, the effective rates of fluconazole, voriconazole and amphotericin B in the clinical treatment of fungal bacteremia were 70.10%, 74.69% and 96.23%, respectively. Among them, the sensitivity rate of voriconazole to C. tropicalis was lower than that of fluconazole. Conclusions:Candida is the main clinical fungus isolates in hospitals of Shandong province. The resistance rate of C. tropicalis to azole antifungal drugs is on the rise, and the sensitivity of other Candida species to clinically used antifungal drugs is basically stable.

EGFR tyrosine kinase inhibitor (EGFR-TKI) has been used successfully in clinic for the treatment of solid tumors. In the present study, we reported the discovery of from our in-house diverse compound library, which was validated to be a potent and selective EGFR-TKI. showed excellent inhibitory activities against EGFR (IC = 0.81 nmol/L), EGFR (IC = 1.2 nmol/L) and EGFR (IC = 1.1 nmol/L), but was less effective or even inactive against other nine kinases. also displayed excellent antiproliferative activities against a panel of human cancer cell lines, and exhibited the ability to reduce colony formation and wound healing the same as gefitinib. We found that upon oral administration showed better anti-tumor activity in A431 bearing xenograft mouse models compared to gefitinib. In addition, showed better intestinal absorption than gefitinib and had favorable pharmacokinetic properties and microsomal metabolic stability in different species.

Objective To evaluate the effects of turmeric volatile oil (TVO) combined with cisplatin on the proliferation and apoptosis of a human cutaneous squamous cell carcinoma cell line A431,and to explore their mechanisms.Methods Some cultured A431 cells at exponential growth phase were divided into several groups to be treated with 5,10,20,40 and 80 mg/L TVO,as well as high-glucose Dulbecco's modified Eagle's medium (DMEM) containing 1％ dimethyl sulfoxide (DMSO,control group),respectively.After 24-hour treatment,cell counting kit 8 (CCK8) assay was performed to estimate the proliferative activity of A431 cells in the above groups.Some other A431 cells were divided into 4 groups:control group treated with high-glucose DMEM containing 1％ DMSO,TVO group treated with 40 mg/LTVO,cisplatin group treated with 10 mg/L cisplatin,and TVO + cisplatin group treated with 40 mg/L TVO and 10 mg/L cisplatin.After 24-hour treatment,CCK8 assay was performed to estimate the cellular proliferative activity,inverted microscopy to observe changes in cell morphology,fluorescence microscopy to detect cell apoptosis after acridine orange (AO)/ethidium bromide (EB) double-staining,colorimetry to evaluate the activity of Caspase-3 and Caspase-9,and Western blot analysis to determine the protein expression of Caspase-3 and p-glycoprotein.Results After 24-hour treatment with 5,10,20,40 and 80 mg/L TVO,the cell proliferation rates were inhibited by (12.83 ± 6.4)％,(16.27 ± 11.4)％,(21.61 ± 9.1)％,(33.11 ± 2.0)％ and (46.00 ± 3.3)％ respectively,and the inhibition rates were all significantly higher in these groups than in the control group (4.03％ ± 1.4％,all P ＜ 0.05).The 50％ inhibitory concentration (IC50) of TVO at 24 hours was (61.66 ± 1.03) mg/L.Compared with the control group,the proliferation inhibition rates significantly increased in the TVO group,cisplatin group and TVO + cisplatin group (all P ＜ 0.05),suggesting that the combination of TVO and cisplatin showed synergistic inhibitory effects with a combination index of 1.366.Moreover,A431 cells turned round to different extents and became apoptotic in the TVO group and cisplatin group,and the TVO + cisplatin group showed obviously decreased number of cells and a large number of cell debris.The TVO + cisplatin group also showed significantly increased activity of Caspase-3 (1.520 ± 0.115) and Caspase-9 (2.760 ± 0.297) as well as protein expression of Caspase-3 (1.482 ± 0.016) compared with the TVO group (Caspase-3 activity:1.117 ± 0.095;Caspase-9 activity:1.259 ± 0.059;Caspase-3 protein expression:1.156 ± 0.006,all P ＜ 0.01) and cisplatin group (Caspase-3 activity:1.381 ± 0.089;Caspase-9 activity:1.829 ± 0.171;Caspase-3 protein expression:1.296 ± 0.021,all P ＜ 0.01),but significantly decreased p-glycoprotein expression (0.528 ± 0.014) compared with the TVO group (1.311 ± 0.011,P ＜ 0.01) and cisplatin group (1.169 ± 0.012,P ＜ 0.01).Conclusion TVO combined with cisplatin can synergistically inhibit the proliferation of A431 cells and induce cell apoptosis,which may be associated with activation of the caspase system and decreased expression of pglycoprotein.

Objective: To investigate and analyze the impact on PLT recovery of recombinant human thrombopoietin (rhTPO) in severe aplastic anemia (SAA) patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: A retrospective analysis of Hematology Division of General Hospital of Jinan Military Command was conducted in the 85 SAA cases who treated with allo-HSCT from January 2010 to March 2017. According to the administration of medicines for platelets, 85 patients were divided into rhTPO group (n=29), rhIL-11 group (n=27) and blank group (n=29), respectively. The median time of PLT ≥20×10⁹/L, PLT ≥50×10⁹/L, and PLT ≥100×10⁹/L, the numbers of megakaryocytes in marrow smear (25±5) days after transplantation and the quantities of platelet transfusion were analyzed retrospectively. The adverse events of rhTPO and rhIL-11 groups were observed. Results: There were no significant differences in the recovery of granulocytes and PLT ≥20×10⁹/L among the three groups (P>0.05). The time of PLT ≥50×10⁹/L in rhTPO group was shorter than that in blank group [16.5 (11-39) d vs 22 (14-66) d, P<0.05], as well as the time of PLT ≥100×10⁹/L [rhTPO: 23 (12-51) d; rhIL-11: 28 (12-80) d; blank group: 35 (18-86) d, P<0.05]. Platelet transfusions were also less in rhTPO group than in rhIL-11 and blank groups [20 (10-30) U, 30 (10-50) U, 35 (10-70) U, P<0.05]. The counts of megakaryocyte in rhTPO group, rhIL-11 group and blank group were 31.5 (0-200), 12 (0-142) and 11(0-187) (P<0.05), respectively. The difference between rhTPO group and rhIL-11 group was statistically significant (P<0.05), but no difference between rhIL-11 group and blank group (P>0.05). Multivariate analysis showed that rhTPO was an independent factor for platelet recovery [HR=4.01 (95%CI 1.81-9.97), P=0.010]. The rhTPO group had no obvious adverse events. Conclusion rhTPO can promote platelet recovery of SAA patients after allo-HSCT, reduce platelet transfusion with safety.

Objective To understand the status quo of the nurses′ perception of their practice environment and the conflict between work and family,and to explore the influencing factors of the conflict, so as to provide references for nursing managers to alleviate the work-family conflict of the operating room nurses. Methods From October to November in 2016,a total of 190 operating room nurses from 4 hospitals in Qingdao Shandong Province were selected by purposive sampling method and investigated with a general information questionnaire,the practice environment scale of the nursing work index (PES-NWI) and the work family conflict scale. The content of the investigation included the perception of nursing practice environment and the conflict between work and family of operating nurses. The stratified multivariate regression analysis was used to explore the factors affecting the work-family conflict. Results The total score of operating room nurses′perception of the nursing practice environment was (95.48±6.34),and the mean score was (3.08±0.44). The total score of the work-family conflict was (56.67±4.56),and the mean score was (3.15±0.48). The differences of work-family conflict score among nurses with different ages,working years,professional titles,the number of monthly night shifts,marital status and daily working time were statistically significant (P< 0.05). Additionally, the difference of work-family conflict among nurses in different levels of hospitals was statistically significant (P<0.05). The number of night shifts per month and the perception of nursing practice environment are the main factors influencing the work-family conflict. 40.0% of work-family conflicts can be predicted jointly by four dimensions of the nursing administrators′ ability and leading style,the doctor-nurse cooperation,the sufficient of human and material resources and nurses′ participating in hospital affairs in nursing practice environment. Conclusions The operating room nurses consider that the nursing practice environment of operating room is above the moderate level,and the work-family conflict is at the moderate level. The nurses′ perception of nursing practice environment is the main factor affecting the work-family conflict. Nursing managers should pay attention to the creation of optimal nursing practice environment and improve the recognition of it,so as to effectively alleviate the conflict between work and family.
