Objective To investigate the clinicopathological diagnosis and differential diagnosis of leiomyoadenomatoid tumor of the uterus,to avoid clinical misdiagnosis and mistherapy.Methods The clinical histopathological and immunohistochemical features of 3 cases with leiomyo-adenomatoid tumor of the uterus were retrospectively evaluated,and the literatures were also reviewed.Results After hospitalization,before surgery,uterine smooth muscle tumor was diagnosed in 3 cases,adenomyomas were accompanied diagnosis in 2 cases.Through microscopic patterns of tumor and immunohistochemical staining showed,positive for MC and Calretinin,but negative for CD34,leiomyo-adenomatoid tumor of uterus was diagnosed,so gestrinone was stopped to use.Conclusion Pathological features and immunohistochemistry techniques are useful in establishing a correct diagnosis of leiomyo-adenomatoid tumor of the uterus,and avoiding misdiagnosis and mistherapy.

OBJECTIVE:To establish a method for simultaneous determination of 5 kinds residual ethanol,acetone,ethylacetate,N,N-diisopropylethylamine and toluene in favipiravir.METHODS:Headspace GC was adopted.The determination was performed on DB-624 capillary column,temperature programmed.The inlet temperature was 220 ℃,and detector was flame ionization detector with temperature of 250 ℃.Nitrogen was used as carrier gas at flow rate of 2.0 mL/min,split ratio was 10 ∶ 1,headspace equilibrium temperature was 80 ℃,equilibrium time was 20 min and headspace sample size was 1 mL.RESULTS:The linear range was 10.0-501.4 μg/mL for ethanol(r=0.999 9),10.0-501.4 μg/mL for acetone (r=0.999 9),10.1-502.6 μg/mL for ethylacetate (r=0.999 9),0.2-11.4 μg/mL for N,N-diisopropylethylamine (r=0.999 9)and 1.8-89.4 μg/mL for acetone(r=0.999 7).The limits of quantification were 5.3,3.4,5.2,6.1 and 20.4 μg/mL,and the limits of detection were 1.4,1.1,1.3,1.6,5.9 μg/mL.RSD of precision test was lower than 4.0％,and RSDs of acetone in stability and reproducibility tests were both lower than 4.0％.The recoveries were 96.61％-99.70％ (RSD=1.01％,n=9),95.81％-99.50％ (RSD=1.29％,n=9),96.42％-99.76％ (RSD=1.24％,n=9),96.36％-99.30％ (RSD=1.19％,n=9),97.00％-99.51％ (RSD=0.82％,n=9).CONCLUSIONS:The method is simple,accurate,reproducible and can be used for simultaneous determination of 5 organic solvents in favipiravir.

OBJECTIVE:To evaluate the similarity of in vitro dissolution of self-made and original preparation of Ramelteon tablet. METHODS:The paddle method was adopted with rotational speed of 50 r/min,using water,pH1.2 hydrochloric acid solu-tion,pH4.0 acetate buffer solution and pH6.8 phosphate buffer solution as dissolution media,HPLC was used to determine the cu-mulative dissolution of main components of self-made and original preparation of Ramelteon tablet at different time points,dissolu-tion profile was drew,then f2 was used to evaluate its similarity. RESULTS:In the 4 dissolution media,the f2 of self-made and original preparation of Ramelteon tablet was 62.8,80.0,77.7,76.2,respectively,which indicated that the dissolution profiles showed similarity. CONCLUSIONS:The established HPLC is suitable for the dissolution determination of Ramelteon tablet;the dissolution profiles of the self-made and original preparations are similar,it preliminary indicates the prescription and technological rationality of self-made preparation.

A series of farnesylthiosalicylamide derivatives(9a-9k)were designed and synthesized via condensating the carboxyl of farnesylthiosalicylic acid(FTS)with different amines, and the in vitro biological activity was evaluated. It was observed that eight of them displayed strong antitumor activity against five human cancer cells in vitro. Notably, compound 9k exhibited the most active with the IC50 values of 6. 05-8. 16 μmol/L range against the tested cancer cells, which were superior to those of FTS and even comparable to that of sorafenib in vitro. In addition, compound 9k down-regulated the protein of Bcl-2 and increased the expression levels of Bax and caspase-3 proteins, indicating that compound 9k could induce tumor cell apoptosis.

Objective:We try to screen out predictive indicators with higher value by analyzing the differences in clinical and laboratory indicators between severe fever with thrombocytopenia syndrome (SFTS) patients in the intensive care unit (ICU) group and non-ICU group.Methods:The clinical and laboratory index data of 69 SFTS patients diagnosed in the laboratory in a hospital from June to December 2019 were retrospectively collected. According to the clinical outcome of the patients, they were divided into ICU and non-ICU groups. The differences in clinical manifestations and laboratory indicators between the two groups were analyzed. The receiver operating characteristic curve (ROC) was used to screen the more valuable predictive indicators.Results:Compared with the non-ICU group, ICU group SFTS patients had significantly higher procalcitonin (PCT), C-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT), leucine aminopeptidase (LAP), glutamate dehydrogenase (GDH), adenosine deaminase (ADA), cystatin C (Cys C), α-hydroxybutyrate dehydrogenase (α-HBDH), creatine kinase (CK), lactate dehydrogenase (LDH) levels ( W=530.0, P=0.003; W=496.5, P=0.015; W=496.0, P=0.015; W=535.5, P=0.002; W=545.5, P=0.001; W=498.5, P=0.013; W=537.0, P=0.002; W=523.0, P=0.004; W=512.0, P=0.007; W=502.0, P=0.012; W=486.0, P=0.023; W=509.0, P=0.008; W=541.0, P=0.002) and significantly lower platelet count (PLT), indirect bilirubin (IBIL), albumin/globulin ratio(A/G) and superoxide dismutase (SOD) levels ( W=199.0, P=0.024; W=175.5.5, P=0.009; t=-2.9, P=0.004; W=209.5, P=0.036; t=-3.0, P=0.004). ROC result showed that ALP [area under the curve (AUC)=0.804, 95% confidence interval ( CI) (0.679~0.929)] and LDH [AUC=0.805, 95% CI (0.680~ 0.930)] have a higher value for predicting the risk of severe illness. Conclusions:Abnormal liver function, heart function, and renal function indicators in SFTS patients indicate that patients are at risk of exacerbation. Among them, ALP and LDH levels have higher predictive value for risk of severe disease, suggesting that the monitoring of patients with the above symptoms should be strengthened in the clinical nursing process.
