Azvudine and nirmatrelvir/ritonavir (Paxlovid) are recommended for COVID-19 treatment in China, but their safety and efficacy in the elderly population are not fully known. In this multicenter, retrospective, cohort study, we identified 5131 elderly hospitalized COVID-19 patients from 32,864 COVID-19 patients admitted to nine hospitals in Henan Province, China, from December 5, 2022, to January 31, 2023. The primary outcome was all-cause death, and the secondary outcome was composite disease progression. Propensity score matching (PSM) was performed to control for confounding factors, including demographics, vaccination status, comorbidities, and laboratory tests. After 2:1 PSM, 1786 elderly patients receiving azvudine and 893 elderly patients receiving Paxlovid were included. Kaplan-Meier and Cox regression analyses revealed that compared with Paxlovid group, azvudine could significantly reduce the risk of all-cause death (log-rank P = 0.002; HR: 0.71, 95% CI: 0.573-0.883, P = 0.002), but there was no difference in composite disease progression (log-rank P = 0.52; HR: 1.05, 95% CI: 0.877-1.260, P = 0.588). Four sensitivity analyses verified the robustness of above results. Subgroup analysis suggested that a greater benefit of azvudine over Paxlovid was observed in elderly patients with primary malignant tumors (P for interaction = 0.005, HR: 0.32, 95% CI: 0.18-0.57) compared to patients without primary malignant tumors. Safety analysis revealed that azvudine treatment had a lower incidence of adverse events and higher lymphocyte levels than Paxlovid treatment. In conclusion, azvudine treatment is not inferior to Paxlovid treatment in terms of all-cause death, composite disease progression and adverse events in elderly hospitalized COVID-19 patients.

Objective To investigate the efficacy of Fuzheng Hejie Prescription(composed of Scutellariae Radix,Lonicerae Japonicae Flos,Agastachis Herba,Bupleuri Radix,Atractylodis Rhizoma,Glycyrrhizae Radix et Rhizoma,etc.)in the treatment of respiratory viral infections in children and to observe its effect on inflammatory factors and immune function.Methods A total of 203 children with respiratory viral infection of H1N1 virus were randomly divided into 101 cases in the observation group and 102 cases in the control group.Both groups were given the routine treatment for subsiding fever,maintaining water-electrolyte balance,and ensuring enough sleep.And additionally,the control group was given Ribavirin Granules and Ibuprofen Granules,and the observation group was given Fuzheng Hejie Prescription based on the treatment for the control group.The course of treatment covered 7 days.The changes of traditional Chinese medicine(TCM)syndrome scores and the levels of immunological indicators and inflammatory factors in the two groups were observed before and after the treatment.Moreover,the clinical efficacy,symptom resolution time and the incidence of adverse reactions were compared between the two groups of children.Results(1)In the course of the trial,one case fell off in the observation group and 2 cases fell off in the control group,and eventually 100 children in each group were included in the trial.(2)After 7 days of treatment,the total effective rate of the observation group was 93.00%(93/100),and that of the control group was 88.00%(88/100),and the intergroup comparison showed that the therapeutic effect of the observation group was superior to that of the control group,but the difference was not statistically significant(χ2= 1.454,P = 0.228).(3)After treatment,the scores of primary symptoms and secondary symptoms as well as the total TCM syndrome scores in the two groups were decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.01).(4)After treatment,the time for the resolution of clinical symptoms such as fever,cough,expectoration and sore throat in the observation group was significantly shorter than that in the control group(P＜0.01).(5)After treatment,the levels of immunological indicators of T lymphocyte subset CD3+ and CD4+ in the two groups were increased compared with those before treatment(P＜0.05),and the levels of CD8+ and B cells were decreased compared with those before treatment(P＜0.05).The intergroup comparison showed that the increase in the levels of CD3+ and CD4+ as well as the decrease in the levels of CD8+ and B cells of the observation group was significantly superior to that of the control group(P＜0.01).(6)After treatment,the levels of inflammatory factors of serum amyloid A(SAA),C-reactive protein(CRP),serum tumor necrosis factor alpha(TNF-α),soluble interleukin 2 receptor(SIL-2R),and interleukin 6(IL-6)in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the levels of interleukin 2(IL-2)and interferon γ(IFN-γ)ls were all significantly increased compared with those before treatment(P＜0.05).The intergroup comparison showed that the decrease of serum SAA,CRP,TNF-α,SIL-2R,and IL-6 levels and the increase of serum IL-2 and IFN-γ levels in the observation group were significantly superior to those in the control group(P＜0.01).(7)The incidence of adverse reactions in the observation group was 2.00%(2/100),which was significantly lower than that of 8.00%(8/100)in the control group,but the difference was not statistically significant(χ2 = 3.789,P = 0.052).Conclusion Fuzheng Hejie Prescription exerts certain effect in treating children with respiratory viral infection of H1N1 virus,which can effectively decrease children's TCM syndrome scores,regulate the inflammatory response,improve the immune function,accelerate the relief of clinical symptoms and shorten the course of the disease.

OBJECTIVES: To investigate the prevalence of polypharmacy and potentially inappropriate medication (PIM) in elderly patients with heart failure (HF) and their impact on readmission and mortality. METHODS: We conducted a study of 274 participants aged 60 years or older with HF. The prevalence of polypharmacy (defined as the use of five or more medications) was calculated, and the 2019 American Geriatrics Society Beers criteria were applied to access PIMs. Medications and PIMs were characterized at admission and discharge, and changes in prescriptions during hospitalization were compared. The impact of polypharmacy and PIM on readmission and mortality were investigated. RESULTS: The median age of this study population was 68 years old. The median number of prescribed drugs was 7 at admission and 10 at discharge. At discharge, 99.27% of all patients were taking five or more drugs. The incidence of composite endpoint and cardiovascular readmission increased with the number of polypharmacy within 6 months. The use of guideline-directed medical therapy reduced the incidence of composite endpoint events and cardiovascular readmission, while the use of non-cardiovascular medications increased the composite endpoint events. The frequency of PIMs was 93.79% at discharge. The incidence of composite endpoint events increased with the number of PIMs. "PIMs in older adults with caution" increased cardiovascular readmission and "PIMs based on kidney function" increased cardiovascular mortality. Several comorbidities were associated with cardiovascular mortality or non-cardiovascular readmission. CONCLUSIONS Polypharmacy and PIM were highly prevalent in elderly patients with HF, and their use was associated with an increased risk of composite endpoint events, readmission and mortality. Non-cardiovascular medications, "PIMs in older adults with caution", "PIMs based on kidney function" and several comorbidities were important factors associated with hospital readmission and mortality. Our findings highlight the importance of medication optimization in the management of HF in elderly patients.

OBJECTIVE: To investigate the clinical significance of the targeted next-generation sequencing assay for patients with suspected myeloid malignancies. METHODS: A total of 39 hematopenia patients with suspected myeloid malignamies in Department of Hematology of The Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from January 2018 to April 2019 were treated, 20 hot spot genes of myelodysplastic syndrome (MDS) were detected. RESULTS: Regarding the diagnostic type, there were 7 cases of idiopathic cytopenia of undetermined significance (ICUS), 8 cases of clonal cytopenias of undetermined significance (CCUS) and 24 cases of myeloid myeloid malignancies which included 18 cases of MDS, 4 cases of myelodysplastic/myeloproliferative neoplasms (MDS/MPN) and 2 cases of acute myeloid leukemia. Positive mutation was detected in 70.8% (17/24) of myeloid malignancy patients , and 72.7% (16/22) in MDS and MDS/MPN patients. The main mutation types were ASXL1, TET2 and RUNX1. Compared with gene negative group, there were no significant differences in sex, age (＜60 years old or ≥60 years old), proportion of bone marrow blast cells (＜5% or≥5%) and cytogenetics (good, medium and poor) (P＞0.05). Furthermore, all 8 CCUS patients showed positive mutation, and the incidence of double or multiple mutation in CCUS group was significantly lower than that of the MDS and MDS/MPN group (37.5% vs 54.5%) (P=0.002). The mutation types between the two groups were similar, and there was no significant difference in variant allele frequency (P＞0.05). CONCLUSION Our results suggest that there are high rates of double or multiple mutations in myeloid malignancies, especially in patients with MDS and MDS/MPN. Targeted sequencing assay can improve the diagnosis of myeloid malignancies, and guide clinical treatment.

OBJECTIVE: To investigate the clinical characteristics of essential thrombocytopenia (ET) patients with positive mutations including JAK2, CALR, MPL, or negative mutations. METHODS: A total of 66 newly diagnosed ET cases from January 2016 to December 2018 in Department of Hematology, Huaian No.1 People's Hospital affiliated to Nanjing Medical University were analyzed. Statistical analysis data included the patient's sex, age, symptoms, thrombosis and embolism events, spleen omegaly, platelet count (Plt), leukocyte (WBC) count, hemoglobin (Hb), fibrinogen (FIB), thrombus elastic diagram (TEG), serum potassium, blood glucose (GLU), lactate dehydrogenase (LDH), JAK2, CALR and MPL mutations, treatment options, and efficacy. RESULTS: All the patients were not MPL-positive, and divided in three groups: JAK2 mutation (46 cases, 69.7%), CALR mutation (9 cases, 13.6%) and gene negative mutation (11 cases, 16.7%) group. The average age of patients in the JAK2 mutation group was 63.2 years old, and significantly higher than that in the CALR mutation group (51.8 year) and gene negative group (50.2 year) (P＜0.05). Compared with the JAK2 mutation group and gene negative group, the CALR mutation group had lower WBC count (6.3×10/L vs 13.79×10/L) (P=0.003) (6.3×10/L vs 9.70×10/L) (P=0.009). Also the Hb level of patients in CALR mutation group was lower than the JAK2 mutation group (121.22 g/L vs 136.2 g/L) (P=0.036). However, there was higher tumor burden in the CALR mutation group, compared with the gene negative mutation group (300.11 U/L vs 227.4 U/L) (P=0. 033). There was no significant difference among the three groups, such as the Plt counts, serum potassium level, GLU level and FIB level (P＞0.05). In addition, thrombus and embolism appeared in 30.3% (20/66) cases. 18.2% (12/66) cases were complicated with hyperkalemia, which significantly correlated with Plt counts (r=0.518). TEG was performed in 34 patients, of which 41.2% (14/34) had abnormal TEG and 55.9% (19/34) were accompanied by Plt count ＞ 1 000 ×10/L, but there was no significant correlation between them (r=0.134). After routine clinical treatment, all the 66 cases achieved partial or complete hematological remission, but the disease usually repeated. Until now 4.5% (3/66) cases had been converted to myelofibrosis (MF) all with JAK2 mutation, but without advancing to acute myeloid leukemia. CONCLUSION ET patients with JAK2 mutation have higher incidence, moreover were in older age. However, the patients with CALR mutations display lower WBC count and Hb level, but higher tumor burden. In short, the multiple gene mutations of ET showed different clinical features closely relates with the prognosis, thus providing guidance for the clinical diagnosis and treatment.

OBJECTIVE: To investigate the efficacy and prognosis of acute myeloid leukemia (AML) patients with chromosome karyotype abnormalities. METHODS: The clinical features and treatment responses of 91 patients with AML were collected and analyzed retrospectively. The efficacy and survival rate of the AML patients with normal and abnormal chromosome karyotype were compared. RESULTS: Chromosome translocations and monosomal karyotypes were the main heterogeneity of AML. There was no significant difference in complete remission rate and overall response rate between the normal and abnormal karyotype groups, but the recurrence rate was higher in abnormal karyotype group. There was no significant difference in response of AML patients received the standard "3+7 regimen" and pre-excitation chemotherapy in the treatment of normal and abnormal karyotype groups. The relapse free survival time (RFS) was longer in the normal karyotype group, but there was no significant difference in overall survival time (OS). CONCLUSION The abnormal karyotype of AML is an independent prognostic factor, monosomal karyotype shows a poor prognosis, and the recurrence rate in AML patients with monosomal karyotype is higher.

OBJECTIVETo explore the expression of focal adhesion kinase (FAK) in patients with acute leukemia (AL) and its clinical significance.

METHODSThe FAK mRNA levels in leukemic cells of 50 patients with AL and bone marrow mononuclear cells(BMMNC) of 10 healthy controls were measured by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR). The bone marrow cell chromosomes were prepared using direct and short term culture, and karyotyping was performed by R-banding technique.

RESULTSThe expression positive rate of FAK mRNA in leukemic cells of 50 patients with AL was 66.0%, which was significantly higher than that in normal controls (20.0%) (P<0.05). The expression positive rates and levels of FAK mRNA in both ALL and ANLL cells were statistically significantly higher than those in normal controls (P<0.05), but the difference between ALL and ANLL cells was not significant (P>0.05). All the expression- positive rates and levels of FAK mRNA in newly diagnosed AL patients and the relapsed AL patients were significantly higher than those in normal controls (P<0.05), but the difference between the newly diagnosed AL patients and the relapsed AL patients was not significant (P>0.05). Morecover, the expression plsitive rate and levels of FAK mRNA in the remitted patients were lower than those in newly diagnosed and relapsed patients (P<0.05), but were no statistically significantly different from normal controls (P>0.05). The expression- positive rate and level of FAK mRNA in the AL patients with abnormal karyotype were significantly higher than those in the AL patients without abnormal karyotype (P<0.05).

CONCLUSIONFAK mRNA over-express in the leukemia patients, which may be related with the outome of disease, possibly providing novel targeting sites for the treatment of leukemia.

UNLABELLEDObjective：To explore the influence of co-inhibiting mTORC2 and HSP90 on the proliferation and apoptosis of multiple myeloma(MM) cell line U266.

METHODSDuring culture, the human MM cell line U266 were treated with 20 nmol/L of rapamycin, 600 nmol/L 17-AAG, 20 nmol/L of rapamycin + 600 nmol/L 17-AGG and phosphate-buffered saline (PBS), then the growth inhibition rate, morphologic changes, apoptosis rate and the expression of caspase 3 and ATK protein in U266 cells were compared and analyzed.

RESULTSThe rapamycin and 17-AAG both could inhibit the growth of U266 cells, while the inhibitory effect of rapamycin in combination with 17-AAG on growth of U266 cells was significantly higher them that of rapamycin and 17-AAG alone and control (PBS); the apoptosis rate of U266 cells treated with rapamycin, 17-AAG and their combination was higher than that of control PBS groups, and the efficacy of 2 drug conbination was higher than that of control PBS group, and the efficacy of 2 drug combination was superior to single drug. The expression levels of caspase 3 and ATK in U266 cells treated with rapamycin, 17-AAG and their combination were higher and lower than those in control group respectively, and the efficacy of 2 drug combination was superior to signle drug. There were significant difference between them (P<0.05).

CONCLUSIONThe co-inhibition of mTORC2 and HSP90 can suppress the proliferation and induce the apoptosis of MM cells.
