Background and purpose:There are few studies on the quality of life after transanal total mesorectal excision(TaTME)for rectal cancer,and there is a lack of evidence-based research.This study aimed to evaluate the impact of TaTME in comparison to laparoscopic total mesorectal excision(LaTME)on postoperative quality of life in patients.Methods:A retrospective analysis was conducted on clinical and pathological data from rectal cancer patients who underwent LaTME and TaTME between September 2019 and September 2022 at Renhe Hospital,Baoshan District,Shanghai,and Fudan University Shanghai Cancer Center.All the patients completed a set of validated questionnaires one year postoperatively,including the EORCT QLQ-C30,Low Anterior Resection Syndrome(LARS)score,International Prostate Symptom Score(IPSS),Generalized Anxiety Disorder-7(GAD-7),and Patient Health Questionnaire-9(PHQ-9).Comparative analysis of these survey results was performed.The study was approved by the Ethics Committee of Renhe Hospital,Baoshan District,Shanghai.The Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)checklist was followed for this study.Results:A total of 39 patients in the TaTME group and 38 patients in the LaTME group were included.There were no statistically significant differences between two groups regarding demographic variables such as gender and age,as well as clinical factors including tumor distance from the anal verge,tumor stage,and preoperative neoadjuvant treatment protocols.Analysis of EORCT QLQ-C30 results indicated equivalent overall quality of life between the two groups;however,the TaTME group reported significantly more severe insomnia(P=0.020).No significant differences were observed in LARS severity or total scores between the groups,though the TaTME group demonstrated superior functional outcomes in terms of incontinence for liquid stools and clustering of stools(P=0.007,P=0.004).Additionally,both groups exhibited comparable results in IPSS,and levels of depression and anxiety.Conclusion:The findings suggest that TaTME and LaTME yield similar outcomes in terms of anal and urinary function,overall quality of life,and psychological health,indicating that it is a viable and safe alternative to LaTME in terms of postoperative quality of life.

Objective:To investigate the effect of bupivacaine liposome for erector spinae plane block on the quality of postoperative recovery in patients undergoing thoracoscopic lung resection.Methods:From July 2023 to January 2024, 128 American Society of Anesthesiologists Physical Status classification ⅠorⅡ patients of either sex, aged 18-75 yr, with body mass index of 18-32 kg/m 2, scheduled for elective thoracoscopic lung resection at the First Affiliated Hospital of Soochow University, were assigned to either bupivacaine liposome group (BL group) or bupivacaine hydrochloride group (BH group) using a random number table method, with 64 patients in each group. Patients received an ultrasound-guided erector spinae plane block following anesthesia induction. BL group received an injection of bupivacaine liposome 20 ml (266 mg) plus normal saline 10 ml, while BH group received an injection of bupivacaine hydrochloride 20 ml (100 mg) plus normal saline 10 ml. The primary outcome was the Quality of Recovery-15 (QoR-15) score at 24 h postoperatively. Secondary outcomes included the QoR-15 score at 3 days postoperatively, time to first patient-controlled analgesia press, and total opioid consumption within the first 3 days postoperatively. Other outcomes assessed were the time to ambulation, duration of chest tube placement, length of hospital stay, patient satisfaction scores at discharge, and development of adverse reactions during hospitalization. Results:Compared to BH group, QoR-15 scores were significantly increased at 24 h and 3 days postoperatively, the time to first patient-controlled analgesia press was significantly prolonged, the consumption of opioid was reduced within the first 3 days postoperatively, the time to ambulation was shortened, and patient satisfaction scores at discharge were increased in BL group ( P<0.05). There were no statistically significant differences between the two groups in terms of the chest tube duration, length of hospital stay, and incidence of adverse reactions during hospitalization ( P>0.05). Conclusions:Bupivacaine liposome for erector spinae plane block can improve the quality of postoperative recovery in patients undergoing thoracoscopic lung resection.

Objective:To investigate the diagnostic value of prenatal MRI in the detection of abnormal placental cord insertions (APCIs) comparing with prenatal ultrasound and pathological examination.Methods:A retrospective data collection was conducted on 440 patients who underwent both prenatal placental ultrasound and MRI at the Foshan Women and Children Hospital from December 2013 to December 2021. Among them, 37 cases were APCIs confirmed by surgery or pathology. The prenatal placental MRI findings were analyzed and compared with prenatal ultrasound diagnosis. The diagnostic efficacy of prenatal MRI and ultrasound in diagnosing APCIs was calculated.Results:Among the 37 cases of APCIs confirmed by surgery or pathology, 17 cases had marginal cord insertion (MCI), 13 cases had velamentous cord insertion (VCI), 5 cases had vasa previa (VP), and 2 cases had VCI combined with VP. The sensitivity and specificity of ultrasound diagnosis for APCIs were 59.5% (22/37) and 97.8% (394/403), respectively. The sensitivity and specificity of MRI diagnosis for APCIs were 86.5% (32/37) and 98.5% (397/403), respectively. Among the 37 cases of APCIs, prenatal MRI missed diagnosis of 2 cases of MCI, 2 cases of VCI, and misdiagnosed 1 case of VCI as an accessory placenta. MRI identified 10 cases of APCIs missed by ultrasound, including 5 cases of MCI, 2 cases of VP, 2 cases of VCI, and 1 case of combined VCI with VP. Additionally, ultrasound misdiagnosed 4 cases of APCIs, including 2 cases of VCI misdiagnosed as MCI and 2 cases of MCI misdiagnosed as VCI.Conclusions:For APCIs complicated with abnormalities of placental location or morphology, or placental accretion spectrum disease in late pregnancy, MRI has a higher diagnostic efficacy than ultrasound.

【Objective】 To establish an experimental method for detecting phagocytosis of sensitized red blood cells in vitro by flow cytometry. 【Methods】 Mononuclear cells were isolated from the peripheral blood of blood donors and cultured in a cell incubator for 1 hour, and then adherent monocytes were isolated and obtained. Di^b-positive red blood cells (RBCs) were labeled with PKH26 and then sensitized with IgG anti-Di^b. The sensitized RBCs were added to monocytes for in vitro phagocytosis assay. Monocytes were labeled with FITC anti-human CD14, then phagocytosis was measured by flow cytometry, and the phagocytic efficiency was calculated. The method was used to detect the phagocytic efficiency of monocytes on human IgG anti-D sensitized RBCs with different titers. 【Results】 The phagocytic efficiency of monocytes was averaged at 5% (1.2%~7.6%, SD 3.30) versus 81% (71.4%~92.7%, SD 8.65) in the negative versus positive control group, respectively. Phagocytic activity of monocytes mediated by anti-D was correlated with the antibody titer. The phagocytosis efficiency was within 10% when the antibody titer was lower than 32 and increased sharply when the titer was between 32 to 128, it entered a plateau and stabilized at 80% at the titer above 256. 【Conclusion】 A detection platform for detecting phagocytosis-sensitized RBCs in vitro by flow cytometry has been successfully established. It can be used to assess the clinical significance of red blood cell allotype or autologous IgG antibodies.

Objective:To explore the risk factors of bladder recurrence in patients with upper urinary tract urothelial carcinoma (upper tract urothelial carcinoma, UTUC).Methods:We retrospectively analyzed the data of 815 patients underwent radical nephroureterectomy for upper tract urothelial carcinoma between June 2009 to June 2019.There were 519 males and 340 females, aged from 26-93 years old(average 66.5±9.6 years old). 396 patients were renal pelvic caicinoma.463 patients were ureteral caicinoma.675 patients were accompanied with hydronephrosis.664 patients were accompanied with preoperative gross hematuria. Preoperative diagnostic ureteroscopy was performed in 323 cases.283 patients had the history of smoking.48 patients were con-comitant with bladder carcinoma at the first diagnosis. Univariate analysis and logistic multivariate regression analysis were used to investigate the risk factors for bladder recurrence after UTUC radical surgery.Results:Among the 859 patients, 407 (47.4%) had low-stage tumor (T is/T a/T 1), 452 (52.6%) had high-stage tumor (T 2-T 4), 110 (12.8%) had low-stage tumor (G 1/G 2), and 749 (87.2%) had high-stage tumor (G 3). 126 (17.2%) of 859 patients had relapse during the follow-up period, the average follow-up time was 17 months, the median recurrence time was 12 months, 101(80.1%) of the relapse occurred within 2 years after operation. In univariate analysis, lower tumor stage ( P=0.047), higher tumor grade ( P=0.043), preoperative hematuria symptom ( P=0.023) and preoperative diagnostic ureteroscopy ( P=0.002) were closely related to bladder recurrence. Taking the above factors into the logistic multivariate regression analysis showed that tumor staging T is/T s/T 1 ( B=0.476, P=0.019), tumor grade G 3( B=0.848, P=0.024), preoperative hematuria symptom ( B=0.521, P=0.048), preoperative diagnostic ureteroscopy( B=0.521, P=0.002) were independent risk factors of postoperative recurrence of bladder. Conclusion:lower tumor stage, higher tumor grade, preoperative hematuria symptom and preoperative diagnostic ureteroscopy are the independent risk factors of postoperative bladder recurrence in patients with UTUC. Routine intravesical chemotherapy should be performed in patients with UTUC with the above risk factors, and routine diagnostic ureteroscopy is not recommended.

Objective To study the biomechanical properties of porous titanium cages used for different lumbar interbody fusion surgeries. Methods The three-dimensional (3D) finite element model of the lumbar spine was constructed, and mechanical parameters of porous materials were obtained by mechanical test.

Objective: Vascular endothelial growth factor A (VEGFA) was investigated as the key protein which might promote the specific metastasis progress of nasopharyngeal carcinoma. Methods: Sixteen specimens of pulmonary metastasis carcinoma and counterparts in primary nasopharyngeal carcinoma tissue were collected from patients. The expression of VEGFA through immunohistochemistry was investigated.VEGFA was knocked down by siRNA in two cell lines of nasopharyngeal carcinoma (CNE-1 and 5-8F), MTT and Transwell test were used to explore the role of VEGFA in praxiology. Then shRNA was used to cultivate the stable CNE-1 cell line with down-regulated-expression of VEGFA. The nude mice models were built through tail vein injection of specific nasopharyngeal carcinoma cells, and lungs were collected to perform further metastasis analysis. Results: Previous genetic studies showed that VEGFA had higher expression in metastasis tissue, and the result was validated in the present study using immunohistochemistry. The percentage of positive cells was 84.8% in pulmonary metastasis group, 51.5% in primary tissue group (t=8.639, P<0.05), average optical density was 0.154 in pulmonary metastasis group, 0.061 in primary tissue group (t=18.791, P<0.05). Low expression of VEGFA inhibited cell viability of optical density value of CNE-1 in siRNA gourp was 0.715, 0.902 in control group (t=7.274, P<0.05); 5-8F in siRNA group was 0.715, 0.935 in control group (t=7.751, P<0.05). Number counting suppressed migration of CNE-1 in siRNA group was 52 per high-power lens, 124 per high-power lens in control group (t=29.380, P<0.05), 5-8F in siRNA group was 65 per high-power lens, 155 per high-power lens in control group (t=18.181, P<0.05). Number counting invasion of CNE-1 in siRNA gourp was 38 per high-power lens, 86 per high-power lens in control group (t=27.665, P<0.05), 5-8F in siRNA group was 52 per high-power lens, 116 per high-power lens in control group (t=40.972, P<0.05) in vitro. Furthermore, knock-down of VEGFA in nasopharyngeal carcinoma reduced the pulmonary metastasis in vivo. Number counting of tumor volumes in shRNA group was 2.4, and 11.0 in control group (t=6.143, P<0.05); average optical density of immunohistochemistry in shRNA group was 0.033, and 0.176 in control group (t=15.734, P<0.05). Conclusions Results above reveal the overexpression of VEGFA in nasopharyngeal carcinoma can facilitate the pulmonary metastasis. Targeting VEGFA may provide a new biomarker of clinical study.
