OBJECTIVE To explore the short-term efficacy,safety and related influencing factors of subcutaneous immunotherapy(SCIT)in children with allergic rhinitis(AR).METHODS Retrospective analyzed the clinical data of 147 children with AR who underwent SCIT at Shenzhen Hospital of Southern Medical University from August 2020 to May 2024.The clinical characteristics and laboratory parameters were collected,the visual analogue scale(VAS),total symptom score(TSS),total medication score(TMS)and combined symptom medication score(CSMS)were compared at the baseline and 3,6 and 12 months after treatment.The incidence of local adverse reactions(LRs)and systemic adverse reactions(SRs)during treatment was also documented.RESULTS A total of 147 children with AR aged 5-18 years were included in the study.A significant reduction was observed in VAS,TSS,TMS and CSMS at months 3,6 and 12 of follow up compared with baseline(all P<0.001),and the short-term onset time was months 3 after treatment.The level of VitD3 in the effective group was significantly higher than that in the ineffective group(P<0.001).Serum VitD3 level was negatively correlated with clinical symptom(R=-0.3,P=0.026).The total number of injections in 147 children was 3201.LRs occurred in 52 children(35.4％),the number of injections was 69(2.2％).SRs occurred in 21 children(14.3％),and the number of injections was 34(1.1％).No grade Ⅲ or Ⅳ SRs occurred.In the logistic regression analysis,body mass index(BMI)was a risk factor for LRs(OR:2.220,95％CI:1.009-4.887,P=0.048).CONCLUSION SCIT demonstrates significant early efficacy and a favorable safety profile safety in children with AR.Serum Vitamin D3 deficiency can affect the short-term efficacy of SCIT.Overweight and obese children are prone to develop local adverse reactions.

Objective:To explore the technique methods and clinical application value of β-electrode (a plasma needle shape electrode) assisted laparoscopic repair of complex vesicovaginal fistula (VVF).Methods:Clinical data of one patient with complex VVF admitted to Chinese PLA General Hospital in April 2025 was retrospectively analyzed. A 36-year-old female presented with urinary leakage 2 months after hysterectomy. Computed tomography urography excluded ureterovaginal fistula. Cystoscopy revealed a 2 cm fistula on the posterior bladder wall with both ureteral orifices adjacent to the fistula edge. The procedure involved two steps: first, transurethral β-electrode pretreatment was performed to protect the ureteral orifices and create a passage from the bladder to the abdominal cavity. Then, laparoscopic separation, suture closure of the fistula, and omental flap coverage were conducted.Results:Total operation time was 180 min (the time of β- electrode operation was 30 min) with intraoperative estimated blood loss of 50 mL. The catheter was removed 3 weeks postoperatively, and the patient voided well without leakage during 4-month follow-up.Conclusions:β- electrode assisted laparoscopic repair of complex VVF have the advantage of precise manipulation, minimal invasion and rapid recovery. No similar technique have been reported domestically or internationally. This technique provides a new approach for the treatment of complex VVF.

Objective To investigate the action mechanism of long non-coding RNA(lncRNA)-N1LR on blood-brain barrier(BBB)after cerebral ischemia-reperfusion(I/R)injury.Methods Primary rat brain microvascular endothelial cells(BMECs)were cultured and treated with OGD/R to simulate cerebral I/R injury.The experiment was divided into normal control group,ln-cRNA-N1LR OGD group,overexpression group(lncRNA-N1LR overexpression after OGD treat-ment)and silence group(lncRNA-N1LR silence after OGD treatment).The mRNA levels of ln-cRNA-N1LR,claudin-5 and occludin in each group were detected by RT-qPCR.The BBB permea-bility was detected by FITC-dextran infiltration assay.The expression of claudin-5 and occludin were detected by Western blotting.Results The mRNA levels of lncRNA-N1LR,occludin and claudin-5 were significantly decreased(0.31±0.01 vs 1.00±0.10,0.42±0.03 vs 1.01±0.13,0.38±0.03 vs 1.00±0.15,P＜0.05),and the BBB permeability was significantly increased(58.79± 3.04 vs 8.87±0.63,P＜0.05)in the OGD group than the control group.The lncRNA-N1LR over-expression group increased the mRNA expression of lncRNA-N1LR,occludin and claudin-5(0.67±0.07 vs 0.31±0.01,0.92±0.02 vs 0.42±0.03,0.70±0.08 vs 0.38±0.03,P＜0.05),and decreased the BBB permeability(41.57±2.43 vs 58.79±3.04,P＜0.05)than the OGD group.lncRNA-N1LR silence resulted in lower mRNA levels of lncRNA-N1LR,occludin and claudin-5(0.21±0.02 vs 0.31±0.01,0.31±0.03 vs 0.42±0.03,0.22±0.02 vs 0.38±0.03,P＜0.05),and enhanced BBB permeability(72.34±1.43 vs 58.79±3.04,P＜0.05)when compared with the OGD group.Conclusion Up-regulation of lncRNA-N1LR may play a neuroprotective role by reducing BBB permeability.

Objective To explore the feasibility and safety of prolonging the use time of non-corng needles in totally implantable venous access ports for patients with breast cancer.Methods A total of 100 breast cancer patients implanted in the chest wall totally implantable venous access ports of Zhejiang Cancer Hospital in June to December 2022 were randomly divided equally into 7-day group and 8-day group by means of random number table according to the time of removing the non-destructive needle.Catheter function evaluation,catheter-related complications,comfort evaluation and cost calculation were used for investigation and analysis.Results In both groups,blood was returned from the infusion port catheter and the catheter flushed smoothly.There were 1 case of local skin allergy in 7-day group and 2 cases in 8-day group.In the comfort evaluation,comfort accounted for 86%in 7d group and 90%in 8d group,and the difference was not statistically significant(P>0.05).The maintenance cost of the infusion port per capita in the 7d group was higher than that in the 8d group,and the difference was statistically significant(P<0.05).Conclusion Under certain circumstances,after evaluation by nurses,the use time of non-corng needles in totally implantable venous access ports of breast cancer patients can be appropriately prolonged,which can improve work efficiency and reduce costs.

Objective:To evaluate the efficacy of robot-assisted Y-V plasty (RAYV) and laparoscopic Y-V plasty (LYV) in the treatment of refractory bladder neck contracture (BNC) after BPH surgery.Methods:A retrospective analysis was performed for the clinical data of 42 patients with refractory BNC after BPH surgery from January 2020 to July 2023, including 18 RAYV and 24 LYV. There were no significant differences between both groups( P>0.05) in term of median age [68(62, 81) years vs. 70(61, 76) years], median body mass index [20.7(17.6, 26.1) kg/m 2 vs. 19.8(16.3, 25.3) kg/m 2], median Q max [9.4(5.6, 13.2) ml/s vs. 8.9(6.2, 12.2)ml/s], median IPSS [20.5(15, 23) vs. 21.1(17, 23)], median QOL score [4.6 (4, 6) points vs. 4.8 (4, 6) points] and median postvoid residual volume [84.7(58, 125)ml vs. 78.3(50, 120)ml]. Preoperative examination of one patient in the RAYV group showed no contractile function of the external urethral sphincter.The surgical procedure was basically the same for both groups: entering into the retropubic space, and incision of the anterior wall of bladder and prostate urethra was performed in an inverted Y-shaped. After excising the scar around the anterior wall of bladder neck, the apex of inverted V-shaped bladder wall flap is brought to the base of the Y-shaped incision using two 3-0 running suture. The catheter was removed 2 weeks after surgery. Perioperative and follow-up data were compared between the two groups. Results:All surgeries were successfully completed without complications. The difference between RAYV and the LYV group in operation time [71.8(50, 98)min vs. 105.9(71, 143)min] and postoperative drainage removal time [2.7(2, 4)d vs. 4.5(3, 7)d] was statistically significant ( P<0.05). There was no significant difference between both groups in term of intraoperative blood loss [50.4(20, 100) ml vs. 60.8(40, 150) ml] and postoperative hospital stay [4.1(3, 5)d vs. 4.6(3, 7)d]( P>0.05). All patients were followed up with a median follow-up of 16.5(2, 41) months. There was no significant difference between RAYV and LYV in term of postoperative Q max [27.9(11.7, 37.6) ml/s vs. 22.4(12.3, 31.5)ml/s], IPSS[5.1(4, 9) points vs. 4.8(4, 10) points], QOL[1.6(1, 3) points vs. 1.5(1, 3) points] and postvoid residual volume [5.6(0, 15) ml vs. 7.2(5, 20) ml] ( P>0.05). The postoperative bladder neck patency rates in the RAYV group and the LYV group were 94.4%(17/18) and 95.8%(23/24), respectively, with no significant difference( P>0.05). In terms of urinary continence, 1 patient in the RAYV group had no contractile function of the external urethral sphincter before surgery, and none of the 41 patients with good preoperative continence had urinary incontinence after surgery. Conclusions:The effect of RAYV in the treatment of refractory BNC after BPH surgery is comparable to that of LYV, but RAYV can shorten the operation time and postoperative drainage time.

Objective To investigate the characteristics and rules of tongue image in patients with chronic fatigue syndrome(CFS)with different fatigue degree.Methods Totally 917 patients with severe chronic fatigue syndrome(severe CFS group),351 patients with mild chronic fatigue syndrome(mild CFS group)and 1216 healthy controls(healthy control group)were enrolled in the physical examination center of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine.The tongue image data of subjects in the three groups were collected using TFDA-1 digital tongue and face diagnostic instrument,and the color space indexes of RGB,HSI,Lab and YCrCb were used to analyze the tongue image differences of CFS people with different fatigue degrees and the tongue image features of CFS patients with liver-qi stagnation syndrome,damp-heat stasis syndrome and spleen deficiency syndrome.Results Compared with the healthy control group,the tongue image indexes TB-R,TB-G,TB-B,TB-I,TB-L,TB-Y,TC-H,TC-I,TC-L and TC-Y increased in the severe CFS group;TB-S,TB-a,TC-S,TC-a,TC-Cr decreased(P<0.05).TB-R,TB-G,TB-B,TB-I,TB-L,TB-Y,TC-R,TC-G,TC-B,TC-I,TC-L and TC-Y increased in severe CFS group compared with mild CFS group.TB-H and TB-b increased in mild CFS group compared with healthy control group.The comparison of syndromes in severe CFS group showed that TB-a,TB-Cr,TC-S,TC-a,TC-Cr and TB-S increased in liver-qi stagnation syndrome compared to damp-heat stasis syndrome;TB-G,TB-B,TB-I,TB-L,TB-Y,TB-b,TB-Cb,TC-G,TC-B,TC-H,TC-I,TC-L,TC-Y and perAll decreased(P<0.05).Compared with spleen deficiency syndrome,TB-a,TB-Cr,TB-CON,TB-ENT,TB-MEAN,TC-a,TC-Cr,TC-CON,TC-ENT,TC-MEAN increased in liver-qi stagnation syndrome;TB-ASM,TC-S and TC-ASM decreased(P<0.05).Compared with spleen deficiency syndrome,TB-a,TB-b,TB-Cr,TB-Cb,TB-CON,TB-ENT,TB-MEAN,TC-G,TC-B,TC-H,TC-I,TC-L,TC-a,TC-Y,TC-Cr,TC-CON,TC-ENT,TC-MEAN,perAll increased;TB-ASM,TC-S and TC-ASM decreased(P<0.05).The comparison of mild CFS syndrome showed that there was no statistical significance between liver-qi stagnation syndrome and spleen deficiency syndrome(P>0.05).TB-Cr,TC-a,TC-Cr and perAll increased and TC-S decreased in damp-heat stasis syndrome compared with spleen deficiency syndrome(P<0.05).TB-S,TB-a,TB-Cr,TC-S,TC-a,TC-Cr increased,and TB-G,TB-B,TB-I,TB-Cb,TB-b,TC-b and TC-Cb decreased(P<0.05)in liver-qi stagnation syndrome compared with damp-heat syndrome.The distribution trend of TC-S was as follows:dampness-heat syndrome

In the neonatal intensive care unit（NICU），maternal separation（MS）and pain are identified as two of the most prevalent early stressors experienced by infants.These stressors have been demonstrated to result in a range of adverse effects on the developing infant，including but not limited to increased pain sensitivity，alterations in neuroplasticity，dysregulation of the endocrine system，immune response imbalance，as well as the emergence of anxiety and depression.To further elucidate their potential mechanisms，this paper presents a summary of recent animal models investigating neonatal MS and pain，while also reviews advancements in understanding how these early stressors impact organisms and their underlying mechanisms.The objective is to provide novel insights and scientific evidence with a view to prevent potential adverse outcomes for infants in the context of hospitalisation in the NICU.

Objective:To investigated the efficacy and safety of transurethral bladder neck incision and laparoscopic modified bladder neck Y-V plasty in the treatment of bladder neck contracture (BNC)after transurethral resection of prostate (TURP).Methods:The clinical data of 57 patients with BNC after TURP who were treated in the Department of Urology, Sixth People's Hospital, Shanghai Jiaotong University School of Medicine from January 2013 to December 2022 were retrospectively analyzed.And the patients were divided into two groups based on the different surgical approaches. There were 22 cases in the transurethral bladder neck incision group, with an average age of (73.75±7.62) years and the preoperative urinary flow Q max of (3.92±2.73) ml/s. The preoperative International Prostate Symptom Score (IPSS) was (26.92±3.34) points, and the quality of life (QOL) score was (4.83±0.72) points. There were 35 cases in laparoscopic modified bladder neck Y-V plasty group, with an average age of (68.57±9.31) years and the preoperative urinary flow Q max of (2.56±1.27)ml/s. The preoperative IPSS was (27.08±3.06) points, and the QOL score was (5.08±0.84) points. The patients underwent transurethral bladder neck incision: Scar tissue was incised at 3, 9, and 12 o'clock in the bladder neck, and the incision depth reached the external fat of the bladder neck at 3 and 9 o'clock. Patients with significantly elevated bladder neck were treated with plasma electrosurgical resection to remove scar tissue. The patients underwent laparoscopic modified bladder neck Y-V plasty: After proper exposition of the bladder neck, the scar tissue was excised. the anterior bladder wall was incised in an inverted Y-shaped manner, the apex of the V-shaped flap was sutured to the distal urethrotomy to create a widened bladder neck. The postoperative urinary flow Q max, IPSS, and QOL of the two groups were compared. Results:All patients underwent surgeries successfully, with a one-time success rate of 94.3% (33/35) in the laparoscopic modified bladder neck Y-V plasty group, which was higher than the one-time success rate of 68.2% (15/22) in the transurethral bladder neck incision group( P<0.01). There were statistically significant difference in operation time [(31.75±12.81)min vs. (68.57±22.36)min] and postoperative hospital stay [(1.73±0.94)d vs. (5.17±2.12)d] between the transurethral bladder neck incision group and the laparoscopic modified bladder neck Y-V plasty group ( P<0.05). The median follow-up period was 12.6 (7.3, 27.8) months. The IPSS of the transurethral bladder neck incision group and the laparoscopic modified bladder neck Y-V plasty group were (9.92±2.56) points and (7.16±2.21) points, respectively. The QOL was (2.76±1.24) points and (1.31±0.95) points, respectively. The urinary flow Q max at 6 months after operation was (15.13±4.68)ml/s and (19.96±4.17)ml/s, respectively. There was statistical significance( P<0.05). Conclusions:Both laparoscopic modified bladder neck Y-V plasty and transurethral bladder neck incision are safe and effective in the treatment of BNC after TURP, and laparoscopic modified bladder neck Y-V plasty has a better clinical therapeutic effect.

Objective To investigate the feasibility and safety of transanal total mesorectal excision (TaTME) in re-operation for anastomosis recurrence rectal cancer. Methods Five patients with anastomosis recurrence rectal cancer underwent TaTME at Ruijin Hospital between April 2020 and December 2021 were retrospectively enrolled in this study. The peri-operative situation, pathological examination, and short-term follow-up results were analyzed. Results All cases were operated laparoscopic TaTME successfully. The operative time was (206.00±19.49) min without intraoperative complications. One case encountered incorrect dissection plane. Anastomotic leakage occurred in one case and anastomotic stenosis developed in another case. The specimens quality of mesorectum deemed complete in all cases without both positive circumferential resection margin and positive distal resection margin. There was (15.20±2.39) months of median follow-up and one case found defecation disorder. Tumor recurrence, metastasis and tumor-related death were not found. Conclusions For patients with anastomosis recurrence rectal cancer, laparoscopic TaTME procedure is novel type and would be safe and effective surgical approach with satisfactory short-term follow-up.

ObjectiveTo explore the association between dietary retinol intake and prognosis of patients with esophageal squamous cell carcinoma. MethodsThe study enrolled 388 cases with primary esophageal squamous cell carcinoma that was pathologically diagnosed in the first affiliated hospital of Fujian medical university and the cancer hospital of Fujian medical university from July 2014 to August 2019. Chi-square test was used to determine the relationship between retinol and patients' characteristics. Kruskal-Wallis rank sum test was used to analyze the relationship between retinol and multiple nutrients.
