Objective:To measure the hospital culture by using Denison and Schein organizational culture models, hence evaluate hospital culture comprehensively and lay a foundation for improving hospital culture construction.Methods:In October 2019, two kinds of organizational culture models were used to measure the culture of a hospital. Denison organizational culture model was used to measure hospital culture with cultural measurement scale in all staff, and Schein organizational culture model was used from the surface layer, middle layer and core layer by inference and description, based on information consulting, field visiting, personal interviewing, group interviewing and expert discussing.Results:The case hospital culture was externally focused and flexible. There was consistency and conflict between the surface culture and the middle culture, so the deep hypothesis could be inferred and described, and the core culture was presented.Conclusions:The two organizational culture models measure the profile and details of hospital culture from qualitative and quantitative perspectives, and each has its own characteristics and application scenarios.

Objective:To investigate the effectiveness and safety of transurethral low power green laser enucleation of prostate (VREP) after transrectal prostate puncture.Methods:The clinical data of 96 patients with VERP in the First Affiliated Hospital of Xinxiang Medical College from October 2020 to October 2021 were retrospectively analyzed. They were randomly divided into the control group ( n=41) and the observation group ( n=55). The control group did not undergo prostate biopsy before operation, and the observation group underwent transrectal prostate biopsy within 1 week before operation. The general data, perioperative indexes, maximum urinary flow rate ( Qmax), international prostate symptom score (IPSS), quality of life score (QOL) and complications of the two groups were compared before and 3, 6 and 12 months after surgery. Results:Preoperatively, the PSA was higher in the observation group compared with the control group ( P<0.05), and the differences in other general information were not statistically significant (all P>0.05). Compared with the control group, the observation group had longer operation times and heavier resected specimens, and the differences were statistically significant (all P<0.05), but there were no statistically significant differences between the two groups in the comparison of enucleation efficiency, crushing efficiency, postoperative hemoglobin (HGB) decline value, postoperative hospitalization time, and postoperative ureter removal time (all P>0.05). At 3, 6 and 12 months postoperatively, Qmax, IPSS and QOL were significantly improved in the observation group compared with the control group (all P<0.05). However, there was no statistically significant difference between the two groups in the comparison of the above-mentioned indexes in the same period after surgery (all P>0.05). There was no statistically significant difference in the complication rate comparison between the two groups ( P>0.05). Conclusions:Transurethral low-power green laser prostate enucleation after transrectal prostate puncture is efficacious and has a certain degree of safety.

Objective To investigate the value of endoscopic carbon nanoparticles labeling technique assisted in situ resection after neoadjuvant chemoradiotherapy(nCRT)for middle and low locally advanced rectal cancer(LARC).Methods From January 2020 to January 2023,46 cases of middle or low LARC were selected for endoscopic injection of carbon nanoparticles suspension to label the lower edge of the tumor before nCRT,and laparoscopic anterior resection of the rectum was performed after nCRT.The main observations were the visualization of carbon nanoparticles marker during the operation,the length of each area(primary tumor area,tumor regression scar,distal resection margin,and regression area of lower edge of tumor)of surgical specimens and the positive rate of distal resection margins.Results The median interval between injection of carbon nanoparticles suspension and surgery was 105(77-182)d in the46 cases.Carbon nanoparticles remnants were observed on the rectal mucosal surface in all the patients after nCRT by endoscopy.During laparoscopic anterior rectal resection surgeries,carbon nanoparticles marker exposure on the surface of the rectal intrinsic fascia observed in 41 cases(89.1%),of which38 cases were judged as good exposure(the width of marker area≤1.5 cm,which assisted the operator accurately determining the distal surgical margins)and 3 cases were judged as inferior exposure(a larger range of black staining whereas in situ resection of the tumor still achievable).In another 5 cases,the carbon nanoparticles marker could not be observed and were judged as exposure failure.Intraoperative cryopathology showed that all distal resection margins were negative.Measurement of 30 surgical specimens with identifiable primary tumor area showed that the length of resected intestinal canal was 17.9(10.1-25.7)cm,the diameter of primary tumor area was(4.3±0.8)cm,the diameter of scar after tumor regression was 2.5(0.8-4.8)cm,and the length of regression of tumor lower margin was 1.0(0-2.9)cm.The length of distal resection margins in middle rectal cancer(n =17)was3.4(1.5-4.3)cm and in low rectal cancer(n =13)was1.6(0.5-2.8)cm.Conclusion Application of carbon nanoparticles labeling technology before nCRT for rectal cancer can effectively mark the lower margin of the primary tumor in a long time and assist surgeons to precisely remove the primary tumor area.

【Objective】 To explore the risk factors of severe postoperative hemorrhage in patients with staghorn renal calculi treated with mini-percutaneous nephrolithotomy (M-PCNL), and to construct a Bayesian network model to predict postoperative hemorrhage. 【Methods】 A retrospective analysis was conducted on 160 patients with staghorn renal calculi who were treated with M-PCNL by surgeons with equivalent qualifications at the First Affiliated Hospital of Xinxiang Medical College during Jan. 2020 and Jan. 2022.A computer-generated random number method was used to divide them into a modeling group (120 cases) and a validation group (40 cases).Patients in the modeling group were divided into severe bleeding group (38 cases) and non-severe bleeding group (82 cases).The general information of the two groups was compared, and the independent risk factors of severe postoperative hemorrhage were analyzed.A Bayesian network model was constructed using R software, the inference prediction was conducted using Netica software, and the performance of the model was evaluated with receiver operating characteristic (ROC) curve. 【Results】 Multivariate logistic regression analysis showed that renal insufficiency (OR: 2.845, 95%CI: 1.563-6.515), mixmum diameter of stones ≥2 cm (OR: 2.063, 95%CI: 1.824-4.555), operation time ≥90 minutes (OR: 3.632, 95%CI: 2.365-7.11), one-stage operation (OR: 2.321, 95%CI: 1.874-6.332), and multi-channel stone removal (OR: 1.842, 95%CI: 1.366-3.687) were independent risk factors of postoperative severe hemorrhage (P<0.05).Based on the above parameters, a Bayesian network model was established, which was then evaluated with the modeling and validation groups internally and externally.The AUC of the modeling group was 0.879 (95%CI: 0.804-0.931, P<0.001), with sensitivity and specificity being 87.68% and 89.63%, respectively.The AUC of the validation group was 0.875(95%CI: 0.818-0.908, P<0.001), with sensitivity and specificity being 87.55% and 89.40%, respectively.The model showed good discrimination. 【Conclusion】 Renal dysfunction, mixmum diameter of stones ≥2 cm, operation time ≥90 minutes, one-stage operation, and multi-channel stone removal are risk factors of severe hemorrhage in patients after M-PCNL.The prediction model has good predictive ability and can effectively describe the complex mechanism between diseases and risk factors.

OBJECTIVETo explore the effect of nano carbon tattooing on the lesion localization in the early colon cancer for additional surgical procedure after endoscopic resection.

METHODSThirty-five patients with early colon cancer accepted additional surgical procedures after endoscopic resection in Fuzhou General Hospital of PLA from May 2014 to November 2016. All the patients underwent nano carbon tattooing before the end of endoscopic resection: 0.1 ml carbon nanoparticles suspension was respectively injected into the normal intestinal submucosa from 1 cm outside the 4 sites (upper, lower, left and right) of the lesion border by colonoscopy, marking the original lesion location and guiding the subsequent additional surgery. Data of these 35 cases were summarized.

RESULTSAll the 35 cases, including 22 males and 13 females, with a mean age of 46.5 years(range 35-70), completed the endoscopic disposable carbon nano marking, and the mean operative time was 7.5 minutes(range 5-10). No bleeding, no perforation and no adverse reaction occurred. Four to 21(10±3.5) days after endoscopic resection, the patients received the additional surgery as a result of pathological specimens of endoscopic resection in 10 cases of vascular invasion, 7 cases of severe submucosal infiltration, 7 cases of more than grade G2 in tumor budding, 6 cases of poorly differentiated adenocarcinoma and undifferentiated carcinoma, and 5 cases of positive margin. All the patients underwent laparoscopic surgery. The mean time of intraoperative detection and lesion location was 3.0 minutes(range 1-5). All tattooings were clearly visible under the naked eye. The colon wedge resection were performed in 5 cases, colon segment resection in 14 cases, and radical resection of colon cancer in 16 cases. The operative time was 45 to 180(120±30) min, and the blood loss was 50 ~ 200(50±15) ml. There was no intraoperative complications. The first gas passage time was 12 to 48(24±8) h. The postoperative hospital stay was 10 to 3(6.5±2.5) d. There was no postoperative complication and no perioperative mortality.

CONCLUSIONNano carbon tattooing is helpful for the accurate location of primary lesions in the additional surgical operation after endoscopic resection of early colon cancer, and it can improve the safety and precision of surgical procedures, especially for laparoscopic surgery.
