Objective To study the relationship between genetic polymorphisms of CYP2E1 and the susceptibility of the acute leukemia in Gansu population. Methods The C609T polymorphism of CYP2E1 gene was detected by polymerase chain reaction-ligase detection reaction (PCR-LDR) and 1∶1 matched casecontrol method in 100 healthy persons (control group) and 100 patients with acute leukemia (AL group).Results The C2 allele genotype and C1C2/C2C2 genotype of CYP2E1 gene occurred more frequently in AL group (13.5 % and 22 %, respectively) than those in control group (10.5 % and 19 %, respectively), however,both differences showed no statistical significant. Further stratified analysis, the C1C2/C2C2 genotype of CYP2E1 gene occurred more frequently in AML group (27%) than that in control group (19 %), but difference had no statistical significant, too. The occurrence frequency of the C2 allele genotype and C1C2/C2C2 genotype of CYP2E1 gene showed no significant difference in ALL group and control group (x2=0.446, P =0.504>0.05). Conclusion Genetic polymorphisms of CYP2E1 don't correlated to susceptibility of acute leukemia(AML and ALL) in Gansu population.

OBJECTIVE: To explore and compare the effect of clinical characters on quality of life (QOL) of laryngeal carcinoma postoperative patients. METHOD: We performed a retrospective cohort follow up study of 303 patients who underwent operation for laryngeal carcinoma. The Chinese version of the general and the head and neck specific quality of life questionnaires of the European Organization for the Research and Treatment of Cancer (EORTC QLQ-C30 and EORTC QLQ-H&H35) were used to measure the quality of life of those patients in the cohort, to study the relationship between QOL and clinical factors. RESULT: In the 303 cases, there were 78 cases retaining the permanent tracheostomies (59 total laryngectomy and 19 partial laryngectomy); 4 patient retain the nasal feed pipe. Female patients were worse than male patients in the domain of physical function and global QOL (P<0.05). Older patients were worse than younger patients in the domain of physical function and speech (P<0.05). Patients with glottic tumors experience better global QOL than their peers with under glottic or supraglottic tumors. The patients with supraglottic tumor have more problem with swallowings (P<0.05). Earlier stage patients have better suitation in many domains than later stage patients, but III stage have more difficulty with swallowing than IV stage. Patients who accepted minimally invasive operation and laryngofissure have better QOL than those accepted partial laryngectomy or total laryngectomy; total laryngectomee have more problems with physical, emotion function, global QOL, sense, speech, cough and morbid feeling than patients with partial laryngectomy, but less problem with fatigue, pain, dyspnea, swollowing and dry mouth; Patients with partial horizontal laryngectomy have more difficulty with swallowing. In the multivariable analysis, the operation mode was an independent factor to speech problem. Patients who accepted neck dissction have more negative outcomes than patients without neck dissection. In the univariable analysis, the permanent tracheostomy was a notable factor which affected many domains in the quality of life; multivariable analysis showed that permanent tracheostomy was an important factor which worked on global quality of life. CONCLUSION The quality of life was affected by many clinical factors. The operation mode was an independent factor which affect speech problem. Decannulation after partial laryngectomy was very important to keep the quality of life.

Objective: To evaluate the effectiveness of varicella vaccine in varicella outbreaks and to analyze the influencing factors, and to provide a reference for making the targeted prevention and controlling measures. Methods: A total of 3 888 students with no history of varicella were selected from 2 schools with varicella outbreak in Guangdong Province in 2021, a retrospective cohort study was conducted by using questionnaire survey, rate ratio ( RR ) and vaccine effectiveness ( VE ) values were calculated and Logistic regression was uses to analyze the factors influencing the protective effect of varicella. Results: There were 138 confirmed cases of varicella among the participants. There was no significant sex difference in the vaccination rate( χ 2=1.36, P =0.51), but there was significant difference in the vaccinattion rate of different age groups( χ 2=555.82, P <0.01). The overall protective effect of VarV was 66.94%(95% CI =56.17%-77.71%), and the protective effect of 2 doses of vaccine( VE = 90.02% , 95% CI =83.13%-96.90%) was higher than that of 1 dose( VE =49.40%, 95% CI =32.36%-66.44%)( χ 2=24.93, P < 0.01 ). The high fever rates in the vaccinated and unvaccinated groups were 7.69% and 25.81%, with significant difference( χ 2= 6.29 , P <0.05). The rates of moderate and severe skin lesions of vaccinated and unvaccinated groups was 20.00% and 50.00%, respectively, and the difference was statistically significant( χ 2=11.32, P <0.01). The protective effects of varicella vaccine against high fever and moderate to severe rash were 70.19%(95% CI =42.11%-98.27%) and 60.00%(95% CI =38.15%-81.85%). Stratified analysis showed that there were significant differences in different years of vaccination( χ 2=37.87, P <0.05), while there were no significant differences in age of vaccination and vaccine manufacturer ( P >0.05). Conclusion Varicella vaccination can prevent chickenpox infection and reduce the severity of the disease. However, the efficacy of varicella vaccine was affected by vaccination years. It is recommended to improve the vaccination coverage of varicella vaccine to prevent the outbreak of the epidemic.

Objective:To investigate the signaling pathway of inhibiting macrophage phagocytosis of TIR domain-containing protein encoded by Escherichia coli (TcpC) N-terminal ubiquitin ligase active fragments of uropathogenic Escherichia coli. Methods:Bioinformatics software was used to analyze the amino acid sequences and the function of TcpC N-terminal ubiquitin ligase active fragments as well as the functional sites. PCR was performed to amplify tcpc-330, tcpc-450 and tcpc-510 genes and a prokaryotic expression system was constructed to express the target proteins. The recombinant proteins rTcpC-N110, rTcpC-N150 and rTcpC-N170 were purified by Ni-NTA affinity chromatography. LPS in the recombinant proteins was removed by Detoxi-gel chromatography. The expression of MyD88 at protein and mRNA levels in macrophages incubated with rTcpC-N110, rTcpC-N150, rTcpC-N170 or rTcpC-TIR was detected by Western blot and qRT-PCR. The activation of NF-κB signal pathway and the levels of proinflammatory factors in macrophages incubated with the above TcpC protein fragments were measured by Western blot and ELISA, respectively. Results:Cys12, Trp104 and Trp106 in the N-terminal fragment of TcpC were crucial amino acids in maintaining its ubiquitin ligase activity. The target recombinant proteins rTcpC-N110, rTcpC-N150 and rTcpC-N170 were successfully expressed and purified. After Detoxi-gel chromatography, rTcpC-N110, rTcpC-N150 and rTcpC-N170 extracts were undetectable for LPS. TcpC ubiquitin ligase fragments inhibited the expression of MyD88 at protein level, but not affect its expression at mRNA level in macrophages. LPS-induced phosphorylation of NF-κB signaling pathway-related proteins p50 and p65 was significantly inhibited in macrophages treated with TcpC ubiquitin ligase fragments. Moreover, LPS-induced production of pro-inflammatory factors was also significantly inhibited.Conclusions:The recombinant proteins rTcpC-N110, rTcpC-N150 and rTcpC-N170 could inhibit the expression of MyD88 at protein level and suppress the activation of NF-κB signaling pathway, suggesting that they were closely related to the inhibition of innate immune activity of macrophages.

Objective:To investigate the role of TcpC in uropathogenic Escherichia coli (UPEC)-induced cystitis in mice and to preliminarily analyze the pathogenic mechanism. Methods:C57BL/6 mice were injected with 10 9 CFU wild-type UPEC CFT073 (CFT073 wt) or tcpc gene-deleted mutant (CFT073 Δ tcpc) from urethra into bladder to construct the mouse model of cystitis. The mice were sacrificed 3 d after infection and the bladders were taken to observe the gross pathological changes. Histopathological changes in bladder tissues were observed after HE staining. Immunohistochemistry was used to detect TcpC in bladder tissues. Bacterial loads in urine samples of UPEC-infected mice were counted by tenfold dilution method, and the presence of tcpc gene in the genomic DNA of bacteria from the bladder and urine samples of CFT073 wt-infected mice was measured by PCR. Real-time quantitative RT-PCR (qRT-PCR) and Western blot were performed to detect the expression of TcpC at mRNA and protein levels in macrophages after CFT073 wt infection. The influence of UPEC strains on the activation of NF-κB signaling pathway in macrophages were determined by Western blot. The levels of proinflammatory factors and the bacterial and cell activity after infecting macrophages with UPEC strains were detected by ELISA, laser confocal microscope and fluorescence microscope, respectively. Results:Compared with the mice with CFT073 Δ tcpc infection, CFT073 wt-infected mice had significantly enlarged bladder and severe neutrophil infiltration and abundant TcpC in bladder tissues. The number of bacteria in the urine of CFT073 wt-infected mice was significantly greater than that of the CFT073 Δ tcpc group. PCR results showed that the bacteria in bladder or urine were CFT073 wt. The expression of TcpC at both mRNA and protein levels in macrophages increased significantly after CFT073 wt infection. Moreover, in CFT073 wt-infected macrophages, the expression of IκBα was promoted and the phosphorylation of p65 and the production of proinflammatory factors were suppressed. TcpC was instrumental in the survival and invasion of CFT073 wt in macrophages. Conclusions:TcpC expression increased significantly in mice with CFT073 wt-induced cystitis. TcpC inhibited the activation of NF-κB signaling pathway and the production of proinflammatory factors in macrophages to improve the survival rate of CFT073 wt, which was closely related to the pathogenesis and immune evasion of UPEC.

Blinatumomab, as a novel bispecific antibody targeting CD19 and CD3, can induce T lymphocytes to precisely target CD19 positive B lymphocytes to apoptosis. At present, it is the only bispecific antibody approved for the treatment of hematological malignancies in China. Blinatumomab is effective in the treatment of newly diagnosed, relapsed/refractory, minimal residual disease positive patients with B-cell acute lymphoblastic leukemia (B-ALL) . It can improve the survival of the patients and is well tolerated. The further study of blinatumomab can provide theoretical basis and new ideas for induction therapy, salvage therapy and subsequent hematopoietic stem cell transplantation in patients with B-ALL.

Objective To investigate the efficacy of induction chemotherapy (ICT) followed by concurrent chemotherapy and helical tomotherapy (HT) in the patients with T4b squamous cell carcinoma of nasal cavity and paranasal sinus (SCCNP) for orbital organ preservation and high quality of life.Methods A total of 26 patients with the orbital involvement of T4b SCCNP between May 2008 and March 2013 were analyzed retrospectively.There were 17 males and 9 females;the average age was 54.7 years.The median follow-up time was 25 months (range 4-77 months).The patients received 1-2 cycles ICT with TP (docetaxel 70 mg/m2 on day 1 and cisplatin 40 mg/m2 on day 1-2,every 3 weeks) or TPF (docetaxel 70 mg/m2 on day 1 and cisplatin 70 mg/m2 on day 1-2,5-fu 700 mg/m2 on day 1-5,every 3 weeks),followed by concurrent HT (60-70 Gy) and chemotherapy with TP and/or epidermal growth factor receptor (EGFR) inhibitor.The Kaplan-Meier method was used to determine the 3-year overall survival rate and local control rate.Side-effects were evaluated with the established common terminology criteria for adverse events (CTCAE) version 4.0 criteria.Results All patients completed the planned chemotherapy and 96.2％ (25/26)patients completed the planned radiotherapy.The 3-year overall survival rate,the local control rate and real orbital preservation rate were 56.7％,79.5％ and 80.0％ respectively.The most common acute side effects higher than grade 2 were oral mucositis,radiodermatitis and dry eye syndrome.Conclusion The strategy including ICT followed by CCRT and/or EGFR inhibitor is an effective treatment for T4b SCCNP patients,with minimal toxicities,higher 3-year OS rate and orbital preservation rate,and also provides a new treatment option for T4b SCCNP patients.

Objective:To investigate the association among presenteeism, emotional intelligence, and professional identity among higher vocational nursing interns and the mediating role of emotional intelligence between presenteeism and professional identity, and to provide a basis for clinical intervention.Methods:A questionnaire survey was conducted among 308 higher vocational nursing interns using the general information questionnaire, Wong Law emotional intelligence scale (WLEIS), the Stanford presenteeism scale-6 (SPS-6), and professional identity questionnaire for nurse students (PIQNS). SPSS 22.0 was used for related analyses including descriptive analysis and Pearson correlation analysis, and the mediating role of emotional intelligence was examined based on the Bootstrap method.Results:The higher vocational nursing interns had a total score of (80.57±15.52) for emotional intelligence, (15.91±4.40) for presenteeism, and (64.93±12.83) for professional identity. The Pearson correlation analysis showed that emotional intelligence was positively correlated with professional identity ( r=0.712, P<0.001), and there was a negative correlation between any two of presenteeism, emotional intelligence, and professional identity ( r=-0.282 to -0.256, all P<0.001). The analysis of mediating effect showed that emotional intelligence played a partial mediating role between presenteeism and professional identity and had a mediating effect of -0.512, accounting for 62.14% of the total effect. Conclusions:Emotional intelligence is a mediating factor between presenteeism and professional identity among higher vocational nursing interns, and emotional intelligence can improve their presenteeism and professional identity.
