OBJECTIVE:To investigate the compatibility stability of Salvianolic acid for injection (SAFI) combined with 8 kinds of common solvents. METHODS:Referring to package inserts,SAFI was collected and combined with 0.9% Sodium chlo-ride injection,5% Glucose injection,10% Glucose injection,Compound sodium chloride injection,Mannitol injection,Glycerol fructose and sodium chloride injection,Sodium lactate Ringer's injection,Glucose and sodium chloride injection,250 mL each re-spectively,and then sealed in the dark at the room temperature. The appearance of mixtures were observed,pH value,the number of insoluble particles,maximal absorption wavelength and maximal absorbance were detected,and the contents of salvianolic acid B,rosmarinic acid,lithospermic acid and salvianolic acid Y in mixtures were determined by HPLC at 0,1,2,4,8 h after mix-ing. RESULTS:Under above condition,no obvious change was found in appearance or pH values of the mixtures within 8 h. Maxi-mal absorption wavelength ranged 284.5-286.0 nm. After mixed with Mannitol injection,the number of particles≥10μm(1-8 h af-ter mixing)and particles ≥25 μm(4-8 h after mixing)exceeded the scope of Chinese Pharmacopoeia(2015 edition);the maxi-mal absorbance changed significantly(RSD=9.17%,n=5);the relative content of salvianolic acid B,rosmarinic acid,lithosper-mic acid and salvianolic acid Y decreased by more than 10%(RSD=14.65%,6.45%,8.97%,12.49%,n=5);after mixed with Sodium lactate Ringer's injection,the relative content of rosmarinic acid and lithospermic acid changed greatly (RSD=14.57%, 7.28%,n=5);after mixed with 5% Glucose injection(4-8 h after mixing)and Glycerol fructose and sodium chloride injection(8 h after mixing),the relative content of rosmarinic acid were less than 90%(RSD=6.30%,4.86%,n=5);and the number of particles ≥25μm exceeded the scope of phamcopoeia after mixing with Glycerol fructose and sodium injection(0 h). The number of insoluble particles in other mixtures were in line with the standard of pharmacopoeia;maximal absorbance had no significant change(RSD<5%,n=5),and the relative content change of analytes were all less than 10%. CONCLUSIONS:Clinical appli-cation of SAFI combined with Mannitol injection,Sodium lactate Ringe's injection and Glycerol fructose and sodium injecrion should be avoided. After mixed with 5% Glucose injection,SAFI should be used within 4 h. SAFI can be compatible with 0.9%Sodium chloride injection,10% Glucose injection,Compound sodium chloride injection and Glucose and sodium chloride injec-tion.

ObjectiveTo analyze hospitalized death related factors in elderly patients with nonST-segment elevation myocardial infarction (NSTEMI). MethodsThree hundred and two patients (≥65 years old) with NSTEMI were included. Thirty-two patients of them died in hospital (death group). Their clinical data were retrospectively analyzed and correlated factors for in-hospital death were evaluated. ResultsCompared with survival group, patients in death group were more likely to have 3 or more chronic diseases,heart function killip grades Ⅲ- Ⅳ, heart rate＞ 100/min and peripheral blood WBC count＞10X 10＜'9＞/L on admission (all P＜:0.05). There was no significant difference in fasting plasma glucose level and serum creatinine on admission between the two groups (both P:＞0.05). But after glomerular filtration rate(eGFR) were estimated by the modified abbreviated MDRD equations based on the Chinese CKD patients, patients in death group were more likely to be with renal dysfunction and pulmonary infection (both P＜0.01 ). Multiple logistic regression analysis showed that heart function killip grades Ⅲ-Ⅳ, renal dysfunction evaluated by eGFR, pulmonary infection on admission were the independent predictors for in-hospital death in elderly patients with NSTEMI. ConclusionsCoexistence of 3 or more chronic diseases is a related factor of death and heart function killip grades Ⅲ-Ⅳ, renal dysfunction evaluated by eGFR and pulmonary infection are the independent predictors for in-hospital death in elderly patients with NSTEMI.

Objective:To analyze the clinical characteristics and causes of death of 80 dead cases with confirmed coronavirus disease 2019 (COVID-19).Methods:The clinical data of 80 dead patients with COVID-19 who were admitted to Renmin Hospital of Wuhan University from January 11 to February 11, 2020 were retrospectively analyzed.The laboratory examination indexes (including white blood cells, lymphocytes, procalcitonin (PCT), lactic acid, D-dimmer, fibrinogen degradation products, N-terminal pro-brain natriuretic peptide (N-proBNP), ultra sensitive-troponin I, lactate dehydrogenase (LDH) and CD4 + T lymphocyte) of the patients at the time of admission were compared with the indexes at the last time before death. Statistical analysis was conducted by using paired t test or Wilcoxon′s signed rank test. Results:The median age was 72 years old of the 80 patients, and 78.75%(63/80) of them were older than 60 years. Thirty-six cases (45.00%) were severe and 44(55.00%) were critical at admission. Fifty-eight cases (72.50%) had underlying diseases. The common underlying diseases were hypertension, diabetes mellitus, coronary atherosclerotic heart disease, and chronic obstructive pulmonary disease. Comparing the patients′ first laboratory tests at admission with those before death, white blood cells increased (8.01(4.86, 12.29)×10 9/L vs 12.55(8.25, 17.66)×10 9/L), lymphocytes decreased (0.70(0.46, 0.88)×10 9/L vs 0.54(0.39, 0.75)×10 9/L), PCT increased (0.20(0.11, 0.74) μg/L vs 1.00(0.20, 1.99) μg/L), lactic acid increased (2.10(1.40, 3.10) mmol/L vs 3.10(2.60, 4.10) mmol/L), D-dimmer increased (4.33(0.97, 18.98) mg/L vs 15.29(5.17, 53.44) mg/L), fibrinogen degradation products increased (15.90(3.58, 76.60) mg/L vs 63.14(21.23, 110.67) mg/L), N-proBNP increased (1 078.00(347.35, 2 996.50) ng/L vs 3 439.50(1 576.00, 9 281.50) ng/L), ultra-sensitive troponin I increased (0.08(0.03, 0.17) μg/L vs 0.33(0.14, 2.47) μg/L), LDH increased (397.00(327.00, 523.50) U/L vs 624.00(481.00, 854.00) U/L) and CD4 + T lymphocyte decreased (137.00(104.00, 168.00)/μL vs 97.00(67.00, 128.00)/μL). The differences between the two groups were all statistically significant ( W=238.00, 1 053.50, 150.00, 152.00, 192.00, 190.00, 108.00, 57.00, 53.00 and 40.00, respectively, all P<0.05). All patients received antiviral and respiratory-support therapy and the main cause of death was respiratory failure caused by intractable hypoxemia and multiple organ failure. Among them, seven cases died in one day hospitalization, and 66 cases died in seven days hospitalization. Conclusions:Elderly patients with a variety of chronic underlying diseases have poor prognosis. It′s essential to pay more attention and deal with the above clinical characteristics at an early stage to improve the outcome of the COVID-19 patients.

Objective To investigate the effect of genetic factors on the occurrence of chronic post-thoracotomy pain syndrome ( PTPS) from the perspective of genetic polymorphisms. Methods Two hun-dred patients of both sexes, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, aged 18-80 yr, scheduled for elective video-assisted thoracoscopic radical lung cancer surgery, were enrolled in this study. Blood samples were taken before operation for genotype analysis of 20 SNP loci, such as rs4073 and rs3774932, after DNA extraction. Postoperative multimodal analgesia was applied to maintain the visual an-alogue scale score ＜3. All the patients were followed up for 2-4 months after operation to record the occur-rence of PTPS. The patients were divided into 2 groups according to whether PTPS occurred: non-PTPS group (group N) and PTPS group (group P). Results The incidence of PTPS was 38. 7％ after surgery, and there were 114 patients in group N and 72 cases in group P . There was significant difference in A/T al-lele and genotype frequency at interleukin-8 rs4073 site and NF-κB1 rs3774932 site between the two groups (P＜0. 05). Conclusion Interleukin-8 and NF-kappa B1 genetic polymorphisms are associated with the occurrence of PTPS.

Objective To assess and compare the incidence,clinical characteristics,treatment,and prognosis of acute heart failure patients from different grades hospitals in Beijing.Methods In this prospective internet prognosis registered study (Beijing AHF Registry),a total of 3 335 consecutive patients admitted to 14 emergency departments in Beijing from January 1st 2011 to September 23rd 2012 were enrolled.According to hospital grade,these patients were divided into two groups,349 patients were from secondary hospitals,and 2 956 patients were from tertiary hospitals.Results Among the 3 335 patients,the medium age was 71 (58,79) years,and male accounted for 53.16％.The most common underlying disease were coronary disease (43.27％),hypertension (17.73％),cardiomyopathy (16.07％) etc.The average treatment time in Emergency Department was 66.82 h.The emergency department mortality rate was 3.81％ (127 cases).The 30-day and 1-year cumulative all-cause mortality were 15.3％ and 32.27％,respectively.The 30-day and 1-year cumulative all-cause readmission were 15.64％ and 46.89％,respectively.Compared with patients in tertiary hospitals,patients in secondary hospitals had more onset acute heart failure patients (63.64％ vs.49.93％),shorter emergency department treatment time (12 h vs.41 h),lower discharge rate (3.43％ vs.37.45％) and emergency department mortality(1.58％ vs.4.09％).Compared with those in tertiary hospitals,1-year cumulative all-cause mortality (25.6％ vs.33.2％),cardiovascular disease mortality (20.2％ vs.26.0％),aggravated heart failure mortality (22.4％ vs.28.8％) were lower in secondary hospitals.Following propensity score matching,compared to tertiary hospitals,patients in secondary hospitals showed lower utilization rate of beta-blockers and ACEFARB (4.51％ vs.28.17％,1.41％ vs.9.58％),except the pironolactone.Conclusion Acute heart failure in emergency department is associated with a high mortality rate and readmission rate.There is still a big gap between guidelines recommend medication current treatments for acute heart failure.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.
