Objective:To establish a machine learning model for the diagnosis of clinically significant prostate cancer based on transrectal contrast-enhanced ultrasound parameters and clinically relevant data.Methods:A retrospective analysis was performed on 151 patients in Chongqing University Cancer Hospital who underwent transrectal contrast-enhanced ultrasonography and transrectal ultrasound-guided needle biopsy from November 2018 to September 2021. The time intensity curve was drawn using VueBox software and 12 parameters such as rise time, peak time, average transit time, peak intensity, and rising slope were quantitatively analyzed. Age, total prostate-specific antigen, free prostate-specific antigen, free prostate-specific antigen ratio, volume, prostate-specific antigen density, and transrectal contrast-enhanced ultrasonography parameters, a total of 18 characteristic parameters, were analyzed and screened through relevant attribute values and information gain attribute values. The screening features were trained and tested by the machine learning single algorithm and integrated algorithm, and then the model was evaluated by the F1 value and the area under the ROC curve(AUC).Results:Using the related attribute value and the information gain attribute value, 12 variables and 5 variables were screened out respectively to establish a machine learning model. The model established by the ensemble algorithm was better than the single algorithm. For the two variable selection methods, the AUC (0.810 vs 0.789) and F1 values (0.748 vs 0.742) of the Bagging ensemble algorithm model, which basic algorithm was decision tree, were the highest, followed by Logistic regression and support vector machine(SVM) in order of AUC and F1 values.Conclusions:Based on transrectal contrast-enhanced ultrasound parameters and clinical data, the Bagging ensemble model based on decision tree has the best performance in diagnosing clinically significant prostate cancer.

Objective:To examine the clinical value of rapid detection of drug-resistant bacteria by immunochromatography and the effects of rapid detection on the prognosis of patients with severe intra-abdominal infection complicated by carbapenem-resistant Enterobacteriaceae (CRE) bloodstream infection.Methods:This was a retrospective cohort study. We analyzed clinical data of 73 patients with severe abdominal infections with sepsis or septic shock complicated by CRE bloodstream infection admitted to the general surgery department of Jinling Hospital between February 2022 and February 2023. Patients were divided into a colloidal gold immunochromatographic assay (GICA) group (17 patients) and conventional testing group (56 patients) based on whether a GICA for CRE had been performed on the patients' first blood culture sample during the diagnosis and treatment process. There were no statistically significant differences between the GICA and conventional testing groups in age ([55.9±17.3] vs. [47.6±16.4] years), sex ([16 men vs. one woman ] vs. [41 men vs. 15 women]), median Charlson comorbidity index (3.0[2.0,4.0] vs. 3.0[2.0, 4.8]), septic shock (10 vs. 39), or acute kidney injury (8 vs. 40) (all P>0.05). Both groups routinely underwent traditional bacterial identification and drug susceptibility testing. Additionally, patients in the GICA group were tested directly for positive blood cultures using a GICA carbapenemase test kit. The main outcomes were mortality rates on Days 28 and 90 after the first identification of CRE bloodstream infection in both groups. We also compared the microbial clearance rate, duration of hospitalization and intensive care unit stay, and time from onset of CRE bloodstream infection to initiation of targeted and appropriate antibiotics between the two groups. Results:The rate of microbial clearance of bloodstream infection was significantly greater in the GICA group than in the conventional testing group (15/17 vs. 34/56 [60.7%], χ 2=4.476, P=0.034), whereas the 28-day mortality tended to be lower in the GICA than conventional testing group [5/17 vs. 44.6% [25/56], χ 2=1.250, P=0.264). The 90-day mortality (8/17 vs. 53.6% [30/56], χ 2=0.222, P=0.638), median duration of hospitalization (37.0 [18.0, 46.5] days vs. 45.5 [32.2, 64.8] days, Z=-1.867, P=0.062), and median duration of intensive care unit stay (18.0 [6.5, 35.0] days vs. 32.0 [5.0, 51.8] days, Z=-1.251, P=0.209). The median time between the onset of bloodstream infection and administration of antibiotics was 49.0 (38.0, 69.0) hours in the GICA group, which is significantly shorter than the 163.0 (111.8, 190.0) hours in the conventional testing group ( Z=-5.731, P<0.001). The median time between the onset of bloodstream infection and administration of appropriate antibiotics was 40.0 (34.0, 80.0) hours in the GICA group, which is shorter than in the conventional testing group (68.0 [38.2, 118.8]) hours; however, this difference is not statistically significant ( Z=-1.686, P=0.093). Conclusions:GICA can provide information on carbapenemase- producing pathogens faster than traditional drug sensitivity testing, enabling early administration of the optimal antibiotics. The strategy of 'carbapenemase detection first' for managing bacterial infection has the potential to improve prognosis of patients and reduce mortality rate.

Objective:The purpose of this study was to analyze the course and outcome of patients with combined entero-atmospheric fistulas in open abdomen treatment.Methods:In this retrospective observational study, we collected data on 214 patients with open abdomen complicated by entero-atmospheric fistulas admitted to Research Institute of General Surgery, Jinling Hospital, Affiliated Hospital of Medical School from January 2012 to January 2021. We collected their basic characteristics, aetiology, treatment plan, and prognosis, including the durations of hospitalization and open treatment, time to resumption of enteral nutrition, duration and prognosis of definitive surgery, and overall prognosis.Results:Of the 214 patients with open abdomen complicated with entero–enteral fistulas, 23 (10.7%) died (11 of multiple organ failure caused by abdominal infection, five of abdominal cavity bleeding, four of pulmonary infection, one of airway bleeding, one of necrotizing fasciitis, and one of traumatic brain injury). The remaining 191 underwent definitive surgery at our hospital. The patients who underwent definitive surgery were predominantly male (156 patients, 81.7%); their age was (46.5±2.5) years. Trauma and gastrointestinal tumors (120 cases, 62.8%) predominated among the primary causes. The reasons for abdominal opening were, in order, severe abdominal infection (137 cases, 71.7%, damage control surgery (29 cases, 15.2%), and abdominal hypertension (25 cases, 13.1%). Temporary abdominal closure measures were used to classify the participants into a skin-only suture group (104 cases) and a skin-implant group (87 cases). Compared with the skin-implant group, in the skin-suture-only group the proportion of male patients was lower (74.7% [65/87] vs. 87.5% [91/104], χ 2=5.176, P=0.023), the mean age was older ([48.3±2.0] years vs. [45.0±1.9] years, t=-11.671, P<0.001), there were fewer patients with trauma (32.2% [28 /87] vs. 58.7% [61/104), χ 2=13.337, P<0.001), intensive care stays were shorter ([8.9±1.0] days vs. [12.7±1.6] days, t=19.281, P<0.001), total length of stay was shorter ([29.3±2.0] days vs. [31.9±2.0] days, t=9.021, P<0.001), there was a higher percentage of colonic fistulas (18.4% [16/87] vs. 8.7% [9/104], χ 2=3.948, P=0.047), but fewer multiple fistulas (11.5% [10/87] vs. 34.6% [36/104], χ 2=14.440, P<0.001). As to fistula management, a higher percentage of fistula sealing methods using 3D-printed intestinal stents were implemented in the skin-only suture group (60.9% [53/87] versus 43.3% [45/104], χ 2=5.907, P=0.015). Compared with the implant group, the skin-only suture group had a shorter mean time to performing provisional closure ( [9.5±0.8] days vs. [16.0±0.6] days, t=66.023, P<0.001), shorter intervals to definitive surgery ( [165.0±10.7] days vs. [198.9±8.3] days, t=26.644, P<0.001), and less use of biopatches (56.3% [49/87) vs. 71.2% [74/104], χ 2=4.545, P=0.033). Conclusions:Open abdomen complicated with entero-enteral fistulas is more common in male, and is often caused by trauma and gastrointestinal tumor. Severe intra-abdominal infection is the major cause of open abdomen, and most fistulae involves the small intestine. Collection and retraction of intestinal fluid and 3D-printed entero-enteral fistula stent sealing followed by implantation and skin-only suturing is an effective means of managing entero-enteral fistulas complicating open abdominal cavity. Earlier closure of the abdominal cavity with skin-only sutures can shorten the time to definitive surgery and reduce the rate of utilization of biopatches.

Objective:To investigate the safety and feasibility of transgluteal percutaneous drainage using double catheterization cannula in the treatment of deep pelvic abscess.Methods:A retrospective analysis of the clinical data of patients who underwent transgluteal percutaneous drainage using double catheterization cannula with deep pelvic abscesses admitted to the Jinling Hospital from May 2017 to September 2020 was conducted. Seven patients were enrolled, including 5 males and 2 females, who aged 26-74 (median 53.0) years old, and all of them had digestive fistula. One male patient was punctured again due to the tube falling off, and a total of 7 patients underwent 8 times of transgluteal percutaneous drainage, all under the guidance of CT. The puncture and drainage steps of the double catheterization cannula group are as follows: (1) Locate the puncture point under CT in the lateral position; (2) Place the trocar into the abscess cavity; (3) Confirm that the trocar is located in the abscess cavity under CT; (4) Pull out the inner core and insert into the double catheterization cannula through the operating hole; (5) Confirmthat the double catheterization cannula is located in the abscess cavity under CT; (6) The double catheterization cannula is properly fixed to prevent it from falling off. The white blood cells, C-reactive protein (CRP), procalcitonin, and interleukin-6 (IL-6) of all patients before the drainage and 1 days, 3 days, and 5 days after the drainage were collected, as well as the bacterial culture results of the drainage fluid. The changes of various infection biomarkers before and after the drainage were compared.Results:All 7 patients were cured. No complications such as hemorrhage and severe pain were observed. The average time with drainage tube was 60.8 (18-126) days. Five patients finally underwent gastrointestinal reconstruction surgery due to gastrointestinal fistula. The median serum interleukin-6 of patients before drainage, 1 day, 3 days and 5 days after drainage were 181.6 (113.0, 405.4) μg/L, 122.2 (55.8, 226.0) μg/L, 59.2 (29.0,203.5) μg/L and 64.1 (30.0,88.4) μg/L, respectively.The level of serum interleukin-6 at 3 days and 5 days after drainage was significantly lower than before drainage ( F=3.586, P=0.026). Although the white blood cell count, C-reactive protein, and procalcitonin decreased gradually after drainage compared with before drainage, the difference was not statistically significant (all P>0.05). Conclusion:Transgluteal percutaneous drainage with double catheterization cannula is simple and effective, and can be used for the treatment of deep pelvic abscess.

9. Comparative analysis of transrectal and transperineal biopsy in diagnosis of prostate cancer
Chinese Journal of Interventional Imaging and Therapy 2019;16(9):555-559
Objective: To compare the detection rate of prostate cancer (PCa) of transrectal and transperineal biopsy. Methods: Totally 128 patients with first time diagnosed PCa were enrolled, including 62 patients in transrectal approach group and 66 patients in transperineal approach group. The detection rate of PCa and clinically significant prostate cancer (CsPCa) of biopsy in patients with different total prostate specific antigen (TPSA) levels were compared between two approaches. Among them, 104 cases (42 cases in transrectal approach group and 62 cases in transperineal approach group) underwent CEUS on the basis of routine ultrasound examination, while 83 cases (28 cases in transrectal approach group and 55 cases in transperineal approach group) underwent targeted puncture. The detection rate of PCa and CsPCa of systematic puncture and targeted puncture were compared between the two groups. Results: The detection rate of PCa and CsPCa was 35.48% (22/62) and 25.81% (16/62) in transrectal approach group, 42.42% (28/66) and 28.79% (19/66) in transperineal approach group (P=0.471, 0.676). There was no significant difference in detection rates of PCa and CsPCa between the two approaches at different TPSA levels (all P>0.05). There was no significant difference in PCa detection rates (35.48% [22/62] vs 40.91% [27/66]; P=0.587), positive needle number/total times (14.25% [106/744] vs 14.52% [115/792]; P=0.879) nor CsPCa detection rates (25.81% [16/62] vs 28.79% [19/66]; P=0.676) between the two approaches. There were significant differences in PCa detection rates (35.71% [10/28] vs 14.55% [8/55]; P=0.002) and positive needle number/total times (30.77% [24/78] vs 6.76% [10/148]; P<0.001) between the two approaches. Conclusion: There is no significant difference in the detection rate of PCa and CsPCa between transrectal and transperineal approaches in ultrasound-guided prostate biopsy. CEUS can guide targeted prostate biopsy. Choosing the same patient position and anatomical section as CEUS can improve the detection rate of prostate cancer of biopsy.

Objective To systematical evaluate the effect of Xuebijing injection in the treatment of multiple organ dysfunction syndrome (MODS).Methods With the keywords including Xuebijing, multiple organ dysfunction syndrome, multiple organ dysfunction and multiple organ failure, PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), VIP and Wanfang Data from the database start until March 4th, 2018 were searched for relevant randomized controlled trials (RCTs) related to Xuebijing injection combined conventional treatment versus conventional treatment alone for MODS. The control group received conventional western medicine treatment, including etiological treatment, antibiotics, mechanical ventilation, nutritional support, and comprehensive treatment to maintain fluid, electrolyte, acid and alkali balance. The experimental group was given traditional western medicine combined with Xuebijing injection. The observation parameters included 7-day and 28-day mortality, acute physiology and chronic health evaluationⅡ (APACHEⅡ) and Marshall score, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), the number of platelets, activated partial thromboplastin time (APTT) and prothrombin time (PT). According to the inclusion and exclusion criteria, two evaluators independently screened the literature, extracted data and evaluated the methodological quality of the included studies. RevMan 5.3 software was used for Meta analysis. Funnel plot was used to analyze publication bias.Results A total of 35 RCTs and 2131 patients were enrolled, including 1076 in the experimental group and 1055 in the control group. The results of Meta analysis showed that compared with control group, Xuebijing combined conventional treatment was in favor to decrease the mortality of patients with MODS [7-day mortality: odds ratio (OR) = 0.42, 99% confidence interval (99%CI) = 0.26-0.69,P < 0.00001; 28-day mortality:OR= 0.31, 99%CI= 0.21-0.45,P < 0.00001], also could obviously reduce critical condition degree of APACHE Ⅱ score and the organ function of Marshall score [APACHEⅡ: mean difference (MD) =3.24, 99%CI = 2.00-4.49,P < 0.00001; Marshall score:MD = 1.95, 99%CI = 0.50-3.40,P = 0.0005]. Meanwhile, the results of conventional western medicine combined with Xuebijing in the removal of IL-6 and TNF-α, platelets increase and improvement of PT were better than those of conventional western medicine (IL-6:MD = 5.56, 99%CI = 1.44-9.68, P = 0.0005; TNF-α:MD = 4.97, 99%CI = 3.44-6.50,P < 0.00001; platelets:MD = -50.79, 99%CI = -74.84 to -26.74, P < 0.0001; PT:MD = 4.55, 99%CI = 3.96-5.14,P < 0.00001), however, there was no obvious advantage in improving APTT (MD = 0.96, 99%CI = -5.08-7.00,P = 0.68). The analysis of funnel map showed that the effect points of various studies were mainly centered on the amount of combined effect, and the "inverted funnel" type was generally symmetrical distribution. However, because the number of the included studies was less, the literature bias could not be completely eliminated.Conclusion Xuebijing injection may through its strong cytokines clearance, platelet increase and blood coagulation improvement to protect the organ function in patients with MODS, so as to reduce the mortality and improve the prognosis.
