Objective To explore the application effect of periodic feedback method in pelvic floor function exercise for patients with low anal preservation.Methods A total of 83 rectal cancer patients with low anal preservation admitted to Zhejiang Cancer Hospital from December 2023 to February 2024 were selected as subjects.They were divided into control group(n=42)and experimental group(n=41)by using a random number table method.The control group received routine health education,while experimental group received guidance on periodic feedback method-based pelvic floor exercises.The compliance with pelvic floor muscle exercises,symptom scores for low anterior resection,and quality of life improvement were compared between two groups.Results After intervention,compliance with pelvic floor exercises was higher,symptom scores for low anterior resection was reduced,overall quality of life was improved in experimental group compared to control group(P＜0.05).Conclusion Periodic feedback method can enhance compliance with pelvic floor exercises and improve overall quality of life for rectal cancer patients with low anal preservation.

Objective:To explore the application value of selective transurethral plasma kinetic resection of the prostate (PKRP) and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of diabetes benign prostatic hyperplasia (BPH).Methods:A total of 114 patients with diabetes BPH diagnosed and treated in Lanxi People′s Hospital from September 2020 to September 2023 were retrospectively selected and divided into resection group and enunciation group according to the operation method, with 57 cases in each group. The resection group received selective PKRP and the enucleation group received HoLEP. Preoperative and postoperative stress response indexes were compared between the two groups, as well as urodynamics indexes and complications before and 3 months after surgery.Results:The quality of prostatectomy in the enucleation group was higher than that in the resection group : (39.68 ± 3.02) g vs. (30.25 ± 2.84) g; the operation time, intraoperative blood loss, bladder irrigation time and hospital stay in the enucleation group were lower than those in the resection group: (63.84 ± 5.44) min vs. (72.58 ± 11.33) min, (62.38 ± 15.84) ml vs. (89.54 ± 17.91) ml, (1.84 ± 0.71) d vs. (2.35 ± 0.80) d, (4.98 ± 1.16) d vs.(5.64 ± 1.05) d, there were statistical differences ( P<0.05). The levels of serum cortisol (COR) and norepinephrine (NE) in the enucleation group at 1, 3 d after surgery were lower than those in the excision group [1 d after surgery: (279.76 ± 17.82) ng/L vs. (289.51 ± 18.37) ng/L, (287.44 ± 26.51) ng/L vs. (300.47 ± 28.35) ng/L; 3 d after surgery: (236.58 ± 15.98) ng/L vs. (247.46 ± 16.47) ng/L, (269.13 ± 23.51) ng/L vs. (278.76 ± 25.62) ng/L, there were statistical differences ( P<0.05). Three months after surgery, the maximum urine flow rate in the enucleation group was higher than that in the excision group : (21.51 ± 3.82) ml/s vs. (18.74 ± 4.17) ml/s, and the residual urine volume (RUV) was lower than that in the excision group : (8.47 ± 3.06) ml vs. (10.25 ± 2.43) ml, there were statistical differences ( P<0.05). There was no significant difference in the incidence of urethral stricture and urinary incontinence between the two groups ( P>0.05). Conclusions:HoLEP for the treatment of diabetes BPH can reduce stress response, promote disease recovery, improve urodynamics, and has a safety comparable to that of selective PKRP.

Objective:To explore the role and mechanism of IL-39 in K562 cells.Methods:The expressions of IL-39R and STAT1/STAT3 in K562 cells were detected via qRT-PCR;the protein levels of phospho-STAT1/STAT3 and STAT1/STAT3 in K562 cells were detected by Western blot;the mRNA regulated by IL-39 in K562 cells was predicted by RNA sequencing.Results:rIL-39 significantly promoted the expression of IL-39R in K562 cells;IL-39 affected K562 cells through STAT1 pathway;IL-39 significantly regulated the expression of mRNA in K562 cells,thus potentially affecting a series of biological processes.Conclusion:IL-39 can directly act on K562 cells,alter gene transcriptional expression and inhibit tumor growth through the STAT1 pathway.IL-39 may similarly modulate gene expression profile in human leukemia cells.

Objective To make a comprehensive analysis of the index of benefit and medical service ability of disease,and provide references for the operation management of public hospital based on disease.Methods TOPSIS was used to compre-hensively evaluate the income contribution,income structure,daily income,the proportion of operation/grade 4 operation,DRG-CMI and other indexes.According to the Boston matrix,two-dimensional quadrant analysis was carried out to determine the dominant diseases in the operation management.Results Twelve main diseases in a hospital specialty were analyzed,and the comprehensive scores of two dimensions of benefit and medical service ability were formed.According to the scores,a two-dimen-sional quadrant map was drawn,and the characteristics of diseases in each quadrant were summarized to identify the dominant diseases that contribute greatly to the economic operation and technical difficulty evaluation of the specialty.Conclusion The combined application of TOPSIS and Boston matrix in specialty operation analysis can help public hospital to realize the classifica-tion management of disease balancing benefit and difficulty,so as to optimize the disease structure and improve the utilization rate of medical resources.

Objective:To observe the clinical effect of free perforator flap of deep medial plantar artery and with sensory nerve in reconstruction of soft tissue defect in heel.Methods:From May 2022 to June 2023, a total of 15 patients with soft tissue defect of heels that caused by various reasons were admitted to the Department of Orthopedics, Zhengzhou Orthopaedic Hospital. The patients were 6 males and 9 females aged 21 to 45 years old, at 32 years old in average. The size of defects was 5 cm×8 cm-10 cm×14 cm. Free perforator flaps of deep medial plantar artery with cutaneous medial plantar nerve were used, at 5 cm×8 cm-11 cm×14 cm in size. Cover the first phase of VSD dressing in the supply site, remove it after 1 week, fill the wound with granulation tissue, and then perform full-thickness skin graft.Results:All 15 flaps survived after surgery. Postoperative outpatient follow-up lasted for 8 to 15 (average 12)months. Appearance and texture of the reconstructed heels were satisfactory, the affected feet were able to bear normal weight without obvious tenderness or ulcer formation. The reconstructed heals were resistant to wear and cold with good sensation. TPD of the flaps achieved 5 mm to 7 mm, without sense of heterotopia after rehabilitation. There was no obvious pigmentation or cicatricial contracture.Conclusion:It is satisfactory to apply a free perforator flap of deep medial plantar artery with sensory nerve in reconstruction of soft tissue defect of heel.

Objective: To investigate the incidence, risk factors and survival of bronchiolitis obliterans syndrome (BOS) in patients who had undergone haplo-hematopoietic stem cell transplantation (haplo-HSCT) . Methods: This study retrospectively analyzed clinical data of 444 consecutive patients who underwent haplo-HSCT and survived at least 100 days after transplantation in the First Affiliated Hospital of Soochow University between January 2013 and December 2015. Results: By the end of follow-up on January 1, 2018, 25 patients (5.63%) had BOS (BOS group) . The median onset time of BOS was 448 (165-845) d post transplantation, the 1-year, 2-year and 3-year cumulative incidence of BOS was 1.6% (95%CI 1.5%-1.6%) , 4.8% (95%CI 4.7%-4.8%) and 5.8% (95%CI 5.7%-5.8%) , respectively. Among patients with chronic graft-versus-host disease (cGVHD) , the cumulative incidence at the same intervals was 2.8% (95%CI 2.7%-2.8%) , 9.5% (95%CI 9.4%-9.5%) and 11.5% (95%CI 11.4%-11.6%) , respectively. In the multivariate analysis, the risk factors for BOS were high-risk primary disease, Ⅱ-Ⅳ aGVHD and preceding cGVHD with other organs. The 3-year overall survival (OS) was lower among patients with than those without BOS, but the difference was not significant [71.8% (95%CI 53.9%-89.6%) vs 72.4% (95%CI 68.1%-76.7%) , P=0.400]. Overall 1-year, 3-year survival of patients with BOS from the time of diagnosis was 78.4% (95%CI 61.5%-95.3%) and 37.0% (95%CI 2.5%-71.5%) , respectively, significantly less than those without (93.9% and 89.3%, from day 448 after transplantation, respectively, P<0.001) . Furthermore, we found a significantly higher incidence of transplantation-related mortality (TRM) in patients with compared with patients without BOS (28.2% vs 10.9%, P<0.001) . The main risk factor for OS of BOS patients was the severity of pulmonary impairment at the time of diagnosis. Patients who developed severe BOS had a worse OS than those with moderate and mild BOS (P=0.049) . Conclusion BOS is a severe pulmonary complication of haplo-HSCT. High-risk primary disease, Ⅱ-Ⅳ aGVHD and preceding cGVHD were independent risk factors for BOS. Patients who developed BOS had a worse OS than those without BOS. The main risk factor for OS of BOS patients was the severity of pulmonary impairment.

Objective To investigate the expression of CD133 and CD44 proteins in gastric stromal tumors (GST) and their clinical significances. Methods The expression of CD44 and CD133 proteins in the GST tissues of 112 patients was detected by immunohistochemical staining. The relation between the expression of CD44 and CD133 proteins and the clinicopathological characters was analyzed. The survival and prognosis of GST were also analyzed. Results Both CD44 and CD133 were expressed on the cell membranes. The expression rates of CD44 and CD133 were 58.04 % (65/112) and 42.86 % (48/112) separately; the co-expression rate of CD44 and CD133 was 27.68 % (31/112). CD44 and CD133 were negative in normal peritumoral tissues. No correlation was found between CD44 and CD133 and the clinicopathological parameters including gender, age and lymphatic vessel invasion (all P>0.05), but the expression levels of CD44 and CD133 in patients with the mitotic count ≥ 5/50 high-power field, large diameter and vascular invasion were significantly higher (all P<0.05). No correlation was found between co-expression of CD44 and CD133 and the clinical clinicopathological parameters including gender, age, the mitotic count ≥ 5/50 high-power field and vascular invasion (all P>0.05), but the co-expression level of CD44 and CD133 in patients with tumor diameter ≥5 cm was significantly higher than that in patients with tumor diameter < 5 cm (χ2=5.040, P=0.025). The overall survival rate of the patients with co-expression of CD44 and CD133 was shorter than that in other groups (χ2 = 8.758, P= 0.001). No correlation was found between CD44 and CD133 expression (r=0.126, P=0.210). Multivariate analysis with the Cox regression models showed that the tumor diameter ≥5 cm (P=0.042) and co-expression of CD44 and CD133 (P=0.003) were significantly associated with poor prognosis. Conclusion CD44 and CD133 as robust cancer stem cell markers in GST might be the prognostic factors.
