OBJECTIVE To evaluate mortality prediction by analyzing clinical features and pathogens of patients with candidemia in intensive care unit(ICU).METHODS The clinical data of candidemia cases admitted to ICU of the First Affiliated Hospital of Zhejiang University in recent five years were analyzed retrospectively,including risk factors,accompanied diseases,Candida species,drug sensitivity,mortality and prognosis.RESULTS Seventy five cases with candidemia were diagnosed in recent five years.Single factor Logistic regression analysis combined with multiple conditional Logistic regression model analysis was conducted.Compared to other risk factors,indwelling central venous catheter(97.2% vs 74.3%,P=0.043,OR=6.4,95%CI 1.06-38.72),hypoproteinemia(91.7% vs 56.4%,P=0.020,OR=6.01,95%CI 1.33-27.0)and APACHEⅡ score(19.6?3.7 vs 15.0?3.8,P=0.00,OR=1.36,95%CI 1.15-1.62) were markedly different.CONCLUSIONS Candidemia cases in ICU increase gradually and lead to higher mortality.Indwelling central venous catheter,hypoproteinemia and APACHEⅡ score are related to mortality of candidemia cases.

Objective To report two cases of familial Gitelman syndrome and literature review regarding the updates of relevant genes,classification,treatment,and prognosis.Methods The clinical data of two sisters with Gitelman syndrome were retrospectively analyzed.Results Their blood pressures were within normal range.Hypokalaemic alkalosis,hypomagnesemia,and hypocalciuria were corrected almost completely after three days of intravenous magnesium and potassium infusion,spirolactone and indometacin.However,the maintenance of normal potassium was unsuccessful over one year.Conclusion Hypokalaemic alkalosis,hypomagnesemia,and hypocalciuria were normalized in Gitelman syndrome.There was some debate in regard to using PGE2 synthetase inhibitors.Tolerance of long-term medication will be the big challenge for curative effect.

Objective To observe the effect of Astragalus injection on the expressions of inflammatory cytokines in human primary macrophages stimulated by lipoteichoic acid (LTA) and lipopolysaccharide (LPS),and investigate its effects on inflammatory reactions of Gram-positive (G+) and Gram-negative (G-) bacteria sepsis and its mechanisms.Methods Percoll density gradient centrifugation was used to isolate the human peripheral blood mononuclear cells,then they were purified by immune Anti-Biotin Microbeads with magnetic character and under the induction of recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF),the cells were cultivated for 12 days in vitro,eventually the human monocyte-derived macrophage was formed.The cultured human macrophages were inoculated in 96-well plates (each group 3 wells) and 6-well plates (each group 3 wells).The cells were divided into control group (200 μL DMEM added in each well),LTA 1 mg/L group,LPS 0.1 mg/L group and low astragalus injection (0.1 mg/L) and high astragalus injection (0.2 mg/L) dose groups.After the incubator plates were put in an incubator for 24 hours,the protein content of IL-8 and IL-10 in supernatant were detected by enzymelinked immunosorbent assay (ELISA),and the mRNA expression levels of IL-8 and IL-10 were detected by real time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-qPCR).Results LTA and LPS all can obviously up-regulate the expression levels of pro-inflammatory factor IL-8 and anti-inflammatory factor IL-10 of macrophage.The expressions of IL-8 and IL-10 protein and mRNA in LTA group and LPS group were significantly higher than those in control group after cuhure for 8 hours and 24 hours,the degrees of increment were more significantly at 24 hours [LTA stimute group:IL-8 protein (ng/L,× 103):41.57± 1.90 vs.1.58 ±0.24,IL-8 mRNA (A value):21.49±8.05 vs.1.00±0.16;IL-10 protein (ng/L):5.90±3.02 vs.2.91 ± 1.54,IL-10 mRNA (A value):1.35±0.34 vs.0.95±0.14;LPS stimute group:IL-8 protein (ng/L,× 103):345.00±22.80 vs.5.60±0.31,IL-8 mRNA (A value):29.84 ± 8.93 vs.1.00 ± 0.16,IL-10 protein (ng/L):122.37 ± 39.26 vs.44.79 ± 3.67,IL-10 mRNA (A value):7.38 ± 1.58 vs.1.35 ± 0.34,all P ＜ 0.05].The Astragalus injection could regulate LTA and LPS to stimulate the macrophage to decrease the expression levels of pro-inflammatory factor IL-8 protein and mRNA and increase the expression levels of anti-inflammatory factor IL-10 protein and mRNA in the macrophage;the changes of regulatory effect in the 24 hour-culture of Astragalus injection high dose group was the most significant [LTA stimute group:IL-8 protein (ng/L,×103):22.63±1.91 vs.41.57±1.90,IL-8 mRNA (A value):12.10±1.93 vs.21.49±8.05,IL-10 protein (ng/L):14.03±2.22 vs.5.90±3.02,IL-10 mRNA (A value):10.37±6.08 vs.1.35±0.34;LPS stimute group:IL-8 protein (ng/L,× 103):167.75 ± 19.90 vs.345.01 ±22.80,IL-8 mRNA (A value):15.61 ± 3.63 vs.29.84±8.93;IL-10 protein (ng/L):243.22±14.41 vs.122.37±39.26,IL-10 mRNA (A value):16.14±4.10 vs.7.38± 1.58,all P ＜ 0.05].Conclusions In the process of inflammatory response,the pro-inflammatory and anti-inflammatory factors co-exist simultaneously.Astragalus injection can inhibit the expression levels of pro-inflammatory factor gene and protein in the inflammatory response of G+ and G-bacteria sepsis and in the mean time,it can promote the expression levels of anti-inflammatory factor gene and protein,thus the immune mechanism of sepsis is affected,achieving the balance between pro-inflammation and anti-inflammation.

Objective: To understand the current status and influencing factors of attempts to e cigarettes use among Macao teenager, and to provide evidence for strategies to prevent and control the use of e cigarettes among teenager. Methods: Research data was 2 683 valid questionnaires collected from the "Macao Youth Tobacco Use Survey 2021", representing 19 480 teenagers from grade 1 to 4 in junior middle schools in Macao after sample weighting. Multivariate Logistic regression analysis was used to analyze the factors that may influencing attempts to e cigarettes use. Results: The total percent of attempt using e cigarettes was 11.3%(95% C =10.2%-12.6%), and male(12.1%) was higher than female(10.5%), the difference was statistically significant ( χ 2= 11.01 , P <0.01). Older adolescents (14-16, ≥17 years old), having more pocket money per week, believing e cigarettes to be less harmful, having been taught about the hazards of e cigarettes within 12 months, definitely believing that e cigarettes maked teenager more attractive, having been exposed to second hand smoke at home within 7 days, having seen tobacco advertisements on the Internet within 30 days, smoking by either parent, smoking among best friends were positively associated with attempts to e cigarettes use ( OR=1.48, 3.01, 1.79, 1.34, 1.67, 1.27, 1.33, 1.34, 1.58, 3.53, P <0.01). Conclusion Attempts to e cigarettes use is common among Macao teenagers, and there are many complex influencing factors. It is recommended to strengthen whole society cooperation and promote the prevention and control of teenager s use of e cigarettes through more targeted comprehensive measures.

Objective:To improve the understanding of the diagnosis and treatment of early T-cell precursor acute lymphoblastic leukemia (ETP-ALL).Methods:The clinical data of a patient with ETP-ALL who was misdiagnosed as peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) admitted to the Second Hospital of Lanzhou University in October 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient who presented "inguinal lymphadenopathy" as the first symptom underwent lymph node biopsy and pathological examination at local hospital, and he was diagnosed as PTCL-NOS according to the consultation of another 2 hospitals. After 2 courses of chemotherapy (CHOPE regimen, GLD regimen, unknown specific medication and dosage), the therapeutic efficacy was poor. For further diagnosis and treatment, this patient came to Lanzhou University Second Hospital. Flow cytometry found blast cells in the bone marrow, and then other related examinations were completed, he was finally diagnosed as ETP-ALL. The chemotherapy regimens of Hyper-CVAD and EA were alternatively used, progressive disease (PD) occurred after 3 courses of treatment, and chidamide was added in the 4th and 5th courses of treatment, the disease still progressed, and the patient died after follow-up. The disease course of the patient was about 12 months.Conclusions:ETP-ALL has unique immunophenotypic characteristics. ETP-ALL patients have a low remission rate after conventional induction therapy, high recurrence rate and poor prognosis. Currently, there is no effective standard treatment regimen, and allogeneic hematopoietic stem cell transplantation or timely addition of new drugs may improve the prognosis.

BACKGROUND: The literature recommends that reduced dosage of CPT-11 should be applied in patients with UGT1A1 homozygous mutations, but the impact of UGT1A1 heterozygous mutations on the adverse reactions of CPT-11 is still not fully clear. METHODS: A total of 107 patients with UGT1A1 heterozygous mutation or wild-type, who were treated with CPT-11 from January 2018 to September 2021 in Peking University Third Hospital, were retrospectively enrolled. The adverse reaction spectra of patients with UGT1A1*6 and UGT1A1*28 mutations were analyzed. Adverse reactions were evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) 5.0. The efficacy was evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. The genotypes of UGT1A1*6 and UGT1A1*28 were detected by digital fluorescence molecular hybridization. RESULTS: There were 43 patients with UGT1A1*6 heterozygous mutation, 26 patients with UGT1A1*28 heterozygous mutation, 8 patients with UGT1A1*6 and UGT1A1*28 double heterozygous mutations, 61 patients with heterozygous mutation at any gene locus of UGT1A1*6 and UGT1A1*28. Logistic regression analysis showed that the presence or absence of vomiting (P=0.013) and mucositis (P=0.005) was significantly correlated with heterozygous mutation of UGT1A1*28, and the severity of vomiting (P<0.001) and neutropenia (P=0.021) were significantly correlated with heterozygous mutation of UGT1A1*6. In colorectal cancer, UGT1A1*6 was significantly correlated to diarrhea (P=0.005), and the other adverse reactions spectrum was similar to that of the whole patient cohort, and efficacy and prognosis were similar between patients with different genotypes and patients treated with reduced CPT-11 dosage or not. CONCLUSIONS In clinical use, heterozygous mutations of UGT1A1*6 and UGT1A1*28 are related to the risk and severity of vomiting, diarrhea, neutropenia and mucositis in patients with Pan-tumor and colorectal cancer post CPT-11 therpy. In colorectal cancer, UGT1A1*6 is significantly related to diarrhea post CPT-11 use, efficacy and prognosis is not affected by various genotypes or CPT-11 dosage reduction.
