Objective To study the expression of STIM 1 gene in human hypopharyngeal carcinoma cell line FaDu and its effect on FaDu cell apoptosis .Methods Lentivirus infection was used to knock STIM 1 down in FaDu cells .Group STIM1-siRNA: the expression of STIM1 in FaDu cell was inhibited by STIM 1-siRNA lentivirus .Group control:FaDu cells were infected by negative control siRNA lentivirus . Real-Time PCR was applied to identify the efficacy of lenticirus infection and the expression of STIM 1 in FaDu cells.Western blot was used to identify the expression of STIM 1 protein after lenticirus infection .Flow cytometry assay was performed to detect the apoptosis of FaDu cells in the two groups.The data were statistically analyzed with SPSS 17.0 software.Results Compared with GAPDH (Ct=12.08 ±0.05),the expression of STIM1 in FaDu cells was significant expressed (Ct=22.21 ±0.05,P<0.001).Real-Time PCR analysis the relative mRNA expression of STIM1 in FaDu cells of control group and STIM 1-siRNA group were (1.00 ±0.08) and (0.12 ±0.01) respectively (P<0.001). Western blot showed that the expression of STIM 1 gene and protein in FaDu cells were inhibited significantly after STIM 1-siRNA lentiviral in-fection,which was in accordance with the results of Real-Time PCR analysis.Flow cytometry assay showed that the siRNA-mRNA group had a higher apoptosis percentage (9.81 ±0.56)% compared to the control group (4.36 ±1.32)%,with statistically significant difference (P<0.05).Conclusion STIM1 gene correlated significantly with FaDu cell apoptosis .It inhibits apoptosis of FaDu cells ,and it may be a potential diagnostic and therapeutic target for the hypopharyngeal carcinoma .

With the development of immunosuppressants and optimization of immunosuppressive regimens, the survival rates of kidney transplant recipients and grafts have been significantly increased, whereas the incidence of acute rejection and delayed graft function have also been significantly reduced. However, the standard triple immunosuppressive regimen (calcineurin inhibitor+antimetabolite+glucocorticoid) still cannot effectively control the rejection of transplant kidney. Consequently, immune induction before transplantation has been proposed. Immune induction therapy may delay the application time and reduce the dosage of calcineurin inhibitor, lower the incidence of short-term acute rejection after operation, and improve the middle- and long-term prognosis of the recipients. In this article, research progresses on monoclonal antibody-based immune induction regimen, polyclonal antibody-based immune induction regimen and mesenchymal stem cell-based immune induction regime were investigated, aiming to provide reference for optimizing the immune induction regime for kidney transplantation.

OBJECTIVETo evaluate the inhibition effect of STIM1 gene silencing on tumor growth of human hypopharyngeal carcinoma cell lines FaDu in nude mice.

METHODSSTIM1 gene in FaDu was silenced by lentiviral infection, and the effect of inhibition was detected by Real-time PCR and Western blot after lentiviral infection. Nude mice were divided into 2 groups, 5 mice in each group. Inhibition group: subcutaneous inject FaDu cells which STIM1 expression was inhibited.

CONTROL GROUPsubcutaneous inject FaDu cells infected with negative control siRNA-expressing lentivirus. Tumor volumes were measured by calipers, and small animal imaging was detected by NightOWL system on the day 10, 14, 18 and 22 after tumor inoculated. Tumor weights were evaluated in the day 22 after tumor inoculated. Statistical analysis was performed using standard student test(P value threshold was 0.05).

RESULTSThe expressions of human STIM1 gene and protein in FaDu cells were suppressed effectively after STIM1-siRNA lentiviral infection. The mean tumor volumes of control group and inhibition group were (51±25) mm3 and (40±35) mm3, respectively, on the day 10, (262±107) and (106±41) mm3 on the day 14, (716±226) and (340±158) mm3 on the day, (1 682±592) mm3 and (917±252)mm3 on the day 22 (P<0.05). On the day 22, the tumor weight was (1.22±0.41) g in control group and (0.66±0.26) g in STIM1-siRNA group (P<0.05). Small animal imaging showed that the tumors had a smaller fluorescence range with lower signal intensity in STIM1-siRNA group than in control group on the day 14, 18 and 22.

CONCLUSIONThe expression of STIM1 in human hypopharyngeal carcinoma cell lines FaDu can be inhibited effectively by lentiviral infection, causing the inhibition of tumor formation and growth.

OBJECTIVE To investigate the surgical efficacy and prognostic factors of patients with advanced nasal and sinuses malignancies,in order to provide more reference for surgical plan selection and prognosis evaluation.METHODS A total of 117 patients with advanced nasal and sinuses malignancies were retrospectively chosen in the period from January 2010 to January 2019 in our hospital.The clinical characteristics and follow-up survival data were analyzed,and the independent prognostic factors of advanced nasal and paranasal malignant tumors were evaluated by univariate and multivariate methods.RESULTS The progression free survival rate and overall survival rate were 48.71％and 62.39％,respectively.The median progression free survival time and overall survival time were 32.48 months and 39.80 months,respectively.Univariate and multivariate analysis showed that age,histopathological type,marginal status and whether adjuvant therapy was accepted were independent factors influencing progression free survival time and overall survival time after surgery for advanced nasal and sinus malignancies(P＜0.05).CONCLUSION The surgical efficacy of advanced nasal and sinusoidal malignancies is satisfactory and the clinical prognosis is related to age,marginal status and adjuvant therapy.

Objective To research the performance of direct settlement for allopatry medical insurance at a tertiary specialized children′s hospital in Beijing, and to analyze the basics of these inpatients and the structural characteristics of their diseases, for basis and suggestions for improving the policy of direct settlement of allopatry medical insurance. Methods A statistical description of direct settlement data was made for allopatry medical insurance at this hospital from August 2017 to July 2018, to study the age, hometown, attribute, distribution of inpatient departments and disease distribution of these children. Results The patients mainly came upon referrals, preschool children in most cases. The average daily hospitalization cost of the disease was high relatively, and the number of hospitalizations was high as well. Compared with children inpatients in Beijing, these patients tend to come for surgical treatment for malignant tumors and congenital diseases.Conclusions The allopatry direct settlement of children′s medical insurance settlement is found mostly with diseases those are complicated and severe. The management of such settlement can be improved by cooperating with their local institutions in advance, data checking in the course, simplifying the formalities for special diseases, and the differential reimbursement ratio for these patients.

【Objective】 To investigate the independent risk factors of urinary tract infection (UTI) in recipients under-going renal transplantation of donation after brain death (DBD), so as to provide a theoretical basis for the prevention and control of postoperative UTI. 【Methods】 A retrospective study was conducted for recipients who received renal transplantation of DBD in our hospital during Jan.2021 and Dec.2021. The recipients were divided into the infection group (n=26) and non-infection group (n=74) according to the incidence of UTI 3 months after operation. The risk factors of UTI were identified with univariate and multivariate analyses. 【Results】 The incidence of UTI was 26%. Univariate analysis showed that gender, postoperative urinary fistula, time of indwelling catheter and time of indwelling double J tube were the influencing factors of UTI (P<0.05). Forward stepwise regression analysis showed time of indwelling double J tube (OR=1.086,95%CI:1.003-1.177,P=0.042) and time of indwelling catheter(OR=4.687,95%CI:2.064-10.645, P<0.010) were the independent risk factors of UTI (P<0.05). 【Conclusion】 The time of indwelling catheter and time of indwelling double J tube are the independent factors of UTI after renal transplantation of DBD.
