OBJECTIVE To investigate the current situation of the review and comment on inpatient medical orders in Beijing municipal hospitals， and to put forward countermeasures and suggestions for further improving related work. METHODS A questionnaire survey was conducted to investigate the current situation of the review and comment on inpatient medical orders in 22 Beijing municipal hospitals. The statistical analysis was conducted for the survey results. RESULTS A total of 22 questionnaires were distributed， with recovery effective rate of 100%. The 22 hospitals carried out inpatient medical order comment， but their proportion varied among hospitals （0.88%-98.54%）； medical order comment mainly focused on antibiotics， proton pump inhibitors， anesthetic drugs/class Ⅰ psychotropic drugs， auxiliary drugs and other categories； 205 pharmacists participated in the comment of inpatient medical orders， most of whom hold intermediate or higher professional titles （89.27%）； 21 hospitals conducted inpatient medical order comment and feedback the results to relevant departments/responsible persons， but the intervention situation was not the same. Eighteen hospitals had carried out the review of inpatient medical orders； reviewed drug category was roughly the same as the category involved in the medical order comment； review content involved the suitability of administration routes， dosage， etc. The review was conducted mainly through the cooperation of audit software and pharmacists. CONCLUSIONS The comment and review of inpatient medical orders in Beijing municipal hospitals carried out in an orderly manner， and preliminary results have been achieved； at the same time， it is necessary to further increase the ability of participating pharmacists， improve audit standards， optimize pre-audit （No.ZYLX201805） software， and promote rational drug use among hospitalized patients through doctor-pharmacist collaboration.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective:To compare the effects of unilateral thoracic paravertebal block with lidocaine on hemodynamic and the level of consciousness during double lumen endotracheal intubation.Methods:From June to october 2021,a total of 40 patients American Society of Anesthesiologists(ASA)physical status Ⅰ-Ⅱ,aged 19-65 years,scheduled for elective thoracic sugeries in Peking University Interna-tional Hospital block with under general anesthesia requiring orotracheal intubation were recruited and di-vided into two groups:The double-lumen endobronchial intubation(group C)and double-lumen endo-bronchial intubation after thoracic paravertebal block with lidocaine(group P).After an intravenous an-esthetic induction,the orotracheal double-lumen intubation was performed using a Macintosh direct laryn-goscopy,respectively.Invasive blood pressure(BP)and heart rate(HR)were recorded before and after anesthetic induction,immediately after intubation and 5 min after intubation with 1-minute interval and the intubation time was also noted.Rate-pressure product(RPP)were calculated.Results:After anes-thetic induction,BP and RPP in the two groups decreased significantly compared with their preinduction values.As comparison with their postinduction values,the orotracheal intubation in the two groups caused significant increases in BP,HR and RPP.Diastolic blood pressure(DBP)and mean arterial pressure(MAP)increased significantly and lasted for 1-minute in group C compared with the baseline values.Systolic blood pressure(SBP)was not significant change and DBP increased significantly immediately af-ter intubation in group P.HR of both groups after intubation were significantly higher than their baseline values and lasted for 4 min in group C,HR increased significantly immediately after intubation in group P.SBP,DBP,MAP,HR and RPP after intubation in group P were significantly lower than those of group C during the observation period.The value of BIS was similar between the two groups.Compared with group C,the incidence of SBP greater than 30％and RPP greater than 22 000 was significantly lower in group P in the observation period,and no patient in group P developed RPP greater than 22 000.At the end of the incidence of SBP less than 30％of the basal value and HR less than 30％of the baseline,no severe bradycardia occurred in both groups.Conclusion:During double-lumen endobronchial intubation,unilateral thoracic paravertebal block with lidocaine can provide less hemodynamic response and level of conscionsness.

Purpose To explore the cardioprotective effect of cang-ai volatile oil(CAVO)on rats with cardiac function impairment model under low-pressure and low-oxygen environment in Tibet Plateau based on 7.0T cardiovascular magnetic resonance(CMR)imaging.Materials and Methods Forty SD rats were randomly divided into the normal group,the high altitude model group,the CAVO-treated group and the rhodiola rosea-treated group,with 10 rats in each group.Except for the normal group,the rats in other groups were transferred from the plain(500 m above sea level)to the Tibet Plateau(4 250 m above sea level)for two months,and then administered with the corresponding drugs by gavage for 14 d.The left ventricle function was measured by using a 7.0T high-field strength CMR and myocardial strain was analysed by using tissue tracing technique.HE staining was used to observe the morphology of cardiomyocytes,Masson staining to observe interstitial fibrosis,wheat germ agglutinin staining to observe cardiomyocyte hypertrophy,and transmission electron microscopy to observe the morphological changes of mitochondria in each group.Serum levels of creatine kinase,creatine kinase isoenzyme,lactate dehydrogenase,cardiac troponin T,superoxide dismutase,malondialdehyde and glutathione peroxidase were detected.Intracellular reactive oxygen species levels were detected using flow cytometry.Results The left ventricular ejection fraction of rats in the CAVO-treated group was higher than that of the high altitude model group[(66.61±1.38)％vs.(60.94±3.21)％;t=3.969,P=0.032];meanwhile,the global circumferential strain of the left ventricle in the CAVO-treated group was higher than that of the high altitude model group(-25.68±1.30 vs.-22.84±1.17;t=3.967,P=0.003).HE,Masson and wheat germ agglutinin staining showed hypertrophy and necrosis as well as interstitial fibrosis and ultrastructural disruption of cardiomyocytes in the high altitude model group,which improved after CAVO treatment.The level of cardiac troponin T in the serum of rats with CAVO treatment group was significantly decreased compared with that of the high altitude model group[(314.03±20.05)pg/ml vs.(518.30±18.13)pg/ml;1=13.090,P=0.001].Conclusion CAVO treatment can reduce cardiac injury caused by low-pressure hypoxia in high altitude,and its effect can be detected dynamically and non-invasively by 7.0T high-field strength CMR.

Objective:To analyze clinical, immunoserological, and therapeutic features of patients with anti-p200 pemphigoid.Methods:Clinical data were collected from patients with confirmed anti-p200 pemphigoid at the Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2015 to February 2024. Their clinical, immunoserological, and therapeutic characteristics were retrospectively analyzed.Results:A total of 35 patients were included, with a male-to-female ratio of 2.5∶1 (25 males and 10 females) and ages of 57.74 ± 17.12 years. Two (5.71%) patients were accompanied by psoriasis. In these patients, anti-p200 pemphigoid exhibited heterogeneous clinical phenotypes, mimicking classic bullous pemphigoid (20 cases, 57.14%), linear IgA bullous dermatosis (8 cases, 22.86%), or eczema (4 cases, 11.43%). The positive rates of direct immunofluorescence (DIF), indirect immunofluorescence on salt-split skin (ss-IIF), Western blot analysis with dermal extracts as substrates, and Western blot analysis with laminin γ1 C-terminal region (Lnγ1C) as substrates were 100% (24/24), 82.86% (29/35), 100% (35/35), and 80.64% (25/31), respectively. Among the 35 patients, treatment and follow-up information was available for analysis in 33. Six patients (18.18%) received non-glucocorticoid systemic therapy and topical glucocorticoid therapy, with a follow-up period ( M [ Q1, Q3]) of 19.50 (6.50, 69.25) months, and 1 withdrew the drugs. Sixteen patients received systemic glucocorticoids combined with traditional anti-inflammatory drugs, with a follow-up period of 13.50 (4.25, 18.00) months, the initial dose of glucocorticoids was equivalent to 0.30 - 0.50 mg·kg -1·d -1 of prednisone, and the time to disease control was 15.31 ± 5.23 days; among the 16 patients, 3 experienced fluctuations in disease condition which were alleviated by adding dapsone, and 1 discontinued glucocorticoids. Five patients (15.15%) received systemic glucocorticoids combined with immunosuppressants, with a follow-up period of 26.00 (14.00, 90.00) months, the initial dose of glucocorticoids was equivalent to 0.50 - 0.75 mg·kg -1·d -1 of prednisone, and the time to disease control was 10.20 ± 3.27 days; among the 5 patients, 2 received maintenance treatment with glucocorticoids (5 - 10 mg/d prednisone), 2 withdrew the drugs, and 1 relapsed after discontinuing glucocorticoids. One patient (3.03%) received systemic glucocorticoids combined with rituximab therapy, with a follow-up period of 53 months, and discontinued glucocorticoids thereafter. One patient (3.03%) received systemic glucocorticoids combined with dupilumab therapy, which proved to be effective. Four patients (12.12%) received systemic glucocorticoids combined with Janus kinase inhibitors, and 3 responded well. Conclusions:Anti-p200 pemphigoid presented a heterogeneous clinical profile in this series of patients, but scarring and milia were rare. Some patients showed negative results in Western blot analysis with Lnγ1C as substrates. The prognosis of anti-p200 pemphigoid was usually favorable, and most patients could achieve complete remission and ultimately discontinue medication.

Objective:To analyze clinical and immunoserological features of patients with epidermolysis bullosa acquisita (EBA) .Methods:Clinical data were collected from patients with confirmed EBA at the Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2017 to January 2022, and their clinical and immunoserological characteristics were retrospectively analyzed.Results:A total of 20 patients were collected, including 7 males and 13 females, and they were aged 41.85 ± 18.43 years. Ten patients presented with the classical phenotype of EBA, 8 with the inflammatory phenotype of EBA, and 2 with the mixed phenotype of EBA. Mucosal involvement occurred in 19 cases, nail involvement occurred in 4, scarring was observed in 9, and milia in 13. Indirect immunofluorescence on salt-split skin showed IgG deposition on the dermal side in 19 cases. Enzyme-linked immunosorbent assay for type Ⅶ collagen revealed positive results in 19 cases, with a diagnostic sensitivity of 95%. Western blot analysis with dermal extracts as substrates revealed a protein band with a relative molecular mass of 290 000 in 16 cases, with a diagnostic sensitivity of 80%, and multiple autoantibodies against different basement membrane zone antigens were identified in 3 cases. Fifteen patients received systemic glucocorticoids, including 2 receiving combined immunosuppressive agents and 13 receiving combined anti-inflammatory agents with dapsone and colchicine as the first and second commonly used anti-inflammatory agents respectively; among 5 patients receiving non-glucocorticoid therapy, 2 with inflammatory EBA were sensitive to dapsone and colchicine, while the other 3 patients were lost to follow-up. Totally, 17 patients were followed up for an average duration of 26.21 months. Among the 17 patients, 1 achieved complete remission off therapy, 2 achieved complete remission on minimal therapy, and the remaining 14 patients achieved partial remission.Conclusions:The treatment of EBA is challenging, and anti-inflammatory agents such as dapsone and colchicine are often used. Immunoserological tests are of great value in the diagnosis of EBA.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

OBJECTIVES: The long-term trends of cognitive function and its associations with physical performance remain unclear, particularly in Asian populations. The study objectives were to determine cognitive trajectories in middle-aged and elderly Chinese individuals, as well as to examine differences in physical performance across cognitive trajectory groups. METHODS: Data were extracted from the China Health and Retirement Longitudinal Study. A total of 5,701 participants (47.7% male) with a mean age of 57.8 (standard deviation, 8.4) years at enrollment were included. A group-based trajectory model was used to identify cognitive trajectory groups for each sex. Grip strength, repeated chair stand, and standing balance tests were used to evaluate physical performance. An ordered logistic regression model was employed to analyze differences in physical performance across cognitive trajectory groups. RESULTS: Three cognitive trajectory groups were identified for each sex: low, middle, and high. For both sexes, higher cognitive trajectory groups exhibited smaller declines with age. In the fully adjusted model, relative to the low trajectory group, the odds ratios (ORs) of better physical performance in the middle cognitive group were 1.37 (95% confidence interval [CI], 1.17 to 1.59; p<0.001) during follow-up and 1.40 (95% CI, 1.20 to 1.64; p<0.001) at the endpoint. The ORs in the high trajectory group were 1.94 (95% CI, 1.61 to 2.32; p<0.001) during follow-up and 2.04 (95% CI, 1.69 to 2.45; p<0.001) at the endpoint. CONCLUSIONS Cognitive function was better preserved in male participants and individuals with higher baseline cognitive function. A higher cognitive trajectory was associated with better physical performance over time.

Objective:To analyze clinical and immunoserological features of patients with anti-p200 pemphigoid.Methods:Clinical data were collected from patients with confirmed anti-p200 pemphigoid in Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2015 to October 2021, and their clinical and immunoserological characteristics were retrospectively analyzed.Results:Seven patients with anti-p200 pemphigoid were included. Indirect immunofluorescence on salt-split skin (IIF-SSS) showed that serum IgG antibodies of the 7 patients were located in the dermis of the salt-split skin, and Western blot analysis with dermal extracts as substrates revealed a protein band with a relative molecular mass of 200 000. Four patients presented with classic bullous pemphigoid-like skin lesions, 2 initially presented with eczematous lesions, and 1 presented with linear IgA bullous dermatosis-like skin lesions. Circulating IgG antibodies could recognize the recombinant laminin γ1 C-terminal region in 6 cases. Four patients received different doses of systemic glucocorticoids, 1 of whom was resistant to high-dose systemic glucocorticoids (equivalent to 1.4 mg·kg -1·d -1 prednisone) ; 2 responded well to minocycline and dapsone; 1 was lost to follow-up. Four patients achieved complete remission and discontinued the treatment at a mean follow-up of 22.5 months; 2 received complete remissiona on minimal therapy at a mean follow-up of 8 months. Conclusion:Patients with anti-p200 pemphigoid presented with heterogeneous clinical manifestations, and the recombinant C-terminal fragment of laminin γ1 can serve as a reliable antigen substrate for the detection of autoantibodies in patients with anti-p200 pemphigoid; some patients can eventually achieve complete remission off treatment.
