Purpose To analyze the expression of SNAP23 in esophageal squamous cell carcinoma(ESCC)and its influence on invasion of ESCC cells.Methods A total of 41 cases of ESCC and paired normal adjacent tissue(NAT)were collected.The expression and localization of SNAP23 were detected by immunohistochemical EnVision method.The differences of SNAP23 expression levels between ESCC tissues and NAT tissues were compared to analyze the relationship between SNAP23 expression and clinicopathological characteristics.The expression level of SNAP23 in human immortalized esophageal epithelial cells SHEE and ESCC cell lines TE-1,TE-13 and KYSE150 were detected by Western blot.Lentiviral vector transfection technique was used to construct stable transfection cell lines with knock-down and overexpression of SNAP23 gene.The effect of SNAP23 on invasion of ESCC cell line TE-13 was evaluated by cell invasion experiment.Results The expression of SNAP23 in ESCC was significantly higher(53.7％,22/41)than that in the NAT group(19.5％,8/41),the difference was statistically significant(x2=10.303,P＜0.01).The expression level of SNAP23 in ESCC tissues was significantly correlated with maximum tumor diameter(x2=4.193,P＜0.05)and invasion depth(x2=7.264,P＜0.05),but was not correlated with patient gender,age,tumor site,tumor type,pathologic grade,vascular embolus,nerve invasion and lymph node metastasis(P＞0.05).Compared with human immortalized esophageal epithelial cells SHEE,SNAP23 was highly expressed in ESCC cell lines(P＜0.000 1).Compared with the sh-NT group,the invasion of ESCC cell line TE-13 was inhibited when SNAP23 expression was knocked down(P＜0.000 1);compared with the Vector group,the invasion of ESCC cell line TE-13 was enhanced after overexpression of SNAP23(P＜0.000 1).Conclusion SNAP23 is highly expressed in ESCC tis-sue and cell lines,and its expression level in ESCC tissues is positively correlated with tumor maximum diameter and invasion depth;SNAP23 promotes the invasion of ESCC cells.

Objective To explore the characteristics and prognosis of follicular lymphoma(FL)with bulky disease under rituximab-based first-line treatment.Methods A retrospective analysis was conducted on 525 FL patients diagnosed between September 2009 and September 2021 who received rituximab as a first-line treat-ment[342 patients received rituximab combined with chemotherapy(R-chemo),183 patients received rituximab plus lenalidomide(R2)].The clinicopathologic characteristics,gene mutations,and prognosis of bulky FL patients were analyzed.Results Compared to non-bulky FL patients,bulky FL patients had a significantly higher proportion of lymph node≥5 sites,≥2 extranodal involvement,bone marrow involvement,elevated LDH,and a higher proportion in the high-risk group of FLIPI1 and FLIPI2.Gene sequencing revealed a significantly higher mutation rate of ZNF608 in bulky FL patients compared to non-bulky FL patients.In patients receiving R-chemo as the first-line treatment,there was no significant difference in progression-free survival(PFS)and overall survival(OS)between bulky and non-bulky FL patients.However,in patients treated with R2,the PFS and OS of bulky FL patients was significantly shorter.Conclusions Bulky FL patients compared to non-bulky FL patients have a significantly higher proportion of high-risk baseline characteristics.For bulky FL at diagnosis,chemo-free regimens require further exploration on the basis of R2.

Objective:To explore the long-term efficacy of a modified unilateral cutaneous ureterostomy in bladder cancer patients receiving radical cystectomy.Methods:The medical data of 104 bladder cancer patients who underwent ureterostomy in our hospital from Janurary 2013 to December 2020 were retrospectively analyzed. The patients were divided into unilateral and bilateral group. The unilateral group contained 66 cases, with 53 males and 13 females, average age (71.8±9.8) years, body mass index (BMI)(23.3±3.2)kg/m 2. The bilateral group contained 38 cases, with 33 males and 5 females, average age (75.1±10.8) years; BMI (22.7±3.0)kg/m 2. There was no significant difference in the above characteristics between the two groups ( P>0.05). The pathology, survival status, long-term complications between the two groups were compared. Quality of life was assessed during follow-up using the European Core Questionnaire for Quality of Life in Cancer Patients (EORTC QLQ-C30). Results:The unilateral group contained 46(69.7%) muscle invasive bladder cancer (MIBC) cases, 15 (22.7%) cases with lymph node metastasis, 7 (10.6%) cases with distant metastasis. The bilateral group contained 24(63.2%) muscle invasive bladder cancer(MIBC) cases, 6 (15.8%) cases with lymph node metastasis, 2 (5.3%) cases with distant metastasis. There was no significant difference in disease specific survival between the two groups ( P>0.05). During the follow-up, the incidence of overall complication rate in the unilateral group was significantly lower than that in the bilateral group [43.9% (29/66) vs. 63.2% (24/38), P<0.001]. The incidence of pyelonephritis in unilateral group was significantly lower than that in the bilateral group [16.6%(11/66) vs. 42.1%(16/38), P=0.006]. There was no statistical significance in terms of quality of life before operation in the two groups. After operation, both physical function score[(54.9±7.1) vs.(49.2±6.7)] and emotional function score [(63.1±6.4) vs.(59.9±6.7)] in unilateral group were higher than that in bilateral group ( P<0.05). Conclusions:The modified unilateral cutaneous ureterostomy could achieve relatively low complication rate, and improve the quality of life to some extent compared with bilateral ureterostomy.

OBJECTIVE To establish a quantitative analysis method for the quality control components in Tenghuang jiangu capsules， and predict the possible action mechanism of the quality control components. METHODS Seven key quality control components in Tenghuang jiangu capsules were quantitatively analyzed by UHPLC-Q-Orbitrap HRMS. The “component-target” network was constructed based on network pharmacology， and the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis and gene ontology （GO） function enrichment analysis were further conducted to find the key signaling pathways. RESULTS The average contents of succinic acid， hyperoside， gallic acid， kaempferol， naringin， naringenin and protocatechuic acid in 20 batches of Tenghuang jiangu capsules were 520.92， 67.67， 129.48， 4.74， 397.45， 5.66 and 376.62 μg/g， respectively. The results of network pharmacology showed that the 62 key target genes of the quality control components of the drug included AKT1， TNF， VEGFA， MMP9， PTGS2， etc. They were mainly enriched in cytokine receptor interaction， nuclear factor， tumor necrosis factor， interleukin 17， rheumatoid arthritis， Toll-like receptor and other signal pathways， involving inflammatory reaction， signal transduction， protein phosphorylation and other biological processes， kytoplasm， cell membrane and other cell components， as well as enzyme activity， energy activity and other molecular functions. CONCLUSIONS The established UHPLC- Q-Orbitrap HRMS method can be used for the quantitative analysis of the quality control components of Tenghuang jiangu capsule. Its quality control components may be mapped to inflammatory pathways related to bone diseases such as rheumatoid arthritis and Toll-like receptors through AKT1， TNF， VEGFA and other key targets， so as to play a therapeutic role.

Objective:To evaluate the clinical effects of transurethral thulium laser coagulation combined with hyperbaric oxygen（HBO）therapy in the treatment of radiation-induced hemorrhagic cystitis（RIHC）.Methods:From January 2014 to June 2020，10 patients with gross hematuria were diagnosed as RIHC in the Department of Urology of the Tenth People’s Hospital of Tongji University. Their clinical data were retrospectively analyzed. There were 7 males and 3 females，with an average age of 69.4 yrs（range 47-81）. Their mean baseline hemoglobin level was 91.4 g/L（range 58-123）and mean overactive bladder syndrome score（OABSS）was 7.8（range 3-13）. All patients received transurethral thulium laser coagulation combined with HBO therapy and were followed up at 1，3，6，and 12 months after treatment. The follow-up examination included gross hematuria evaluation，OABSS，detection of hemoglobin，and the count of microscopic red blood cells. Cystoscopies were also performed at month 6 and 12 to assess the therapeutic effects.Results:All patients completed the treatment. No grade 3-4 perioperative complications occurred，and no severe side effects such as severe barotrauma，oxygen poisoning，and decompression sickness were found during HBO therapy. After treatment，the hemoglobin levels at month 1，3，6 and 12 were significantly increased，and the results of OABSS were significantly decreased at all time points. The increases of hemoglobin at month 1 and 3 as well as the decrease of OABSS at month 1 showed statistically significant difference from their former performance，respectively（ P<0.05）. In the follow-up at month 12，the cystoscopies showed that 6 patients were cured，3 patients got their symptoms relieved，while 1 patient still suffered from gross hematuria repeatedly. The total effective rate of the combined treatment was 90%. Conclusion:Transurethral thulium laser coagulation combined with HBO has a high effective rate. It can significantly improve gross hematuria and relieve urinary tract symptoms. Thus it’s an effective treatment method for RIHC.
