A total of 18 pieces of evidence in 7 dimensions were summarized, including risk factors of VA-ECMO lower limb ischemia, evaluation before catheterization, evaluation and monitoring during treatment, prevention of lower limb ischemia, treatment of lower limb ischemia, management of distal perfusion catheter (DPC), and monitoring after VA-ECMO weaning.Conclusion:This evidence summary provides evidence-based recommendations for the prevention and management of lower limb ischemia in VA-ECMO patients, aiming to assist clinical healthcare professionals in developing tailored strategies for the prevention and management of lower limb ischemia based on during VA-ECMO support.

Objective:To analyze measurement results of serum allergen-specific immunoglobulin E (IgE) in patients with eczema/dermatitis.Methods:A retrospective analysis was conducted on serum allergen-specific immunoglobulin E (IgE) levels in 3 051 patients with eczema/dermatitis, who visited the allergy clinic of Huashan Hospital from April 1, 2021 to March 31, 2022. The serum allergen-specific IgE level was detected by using the Phadia allergen detection system, and positive rates of allergens were calculated to determine common inhaled allergens and food allergens in patients with eczema/dermatitis. Comparisons of enumeration data between groups were performed by chi-square test.Results:Among the 3 051 patients with eczema/dermatitis, there were 1 412 with atopic dermatitis and 1 639 were other eczema/dermatitis. Detection of serum allergen-specific IgE showed that 1 629 (53%) patients were positive for allergens, and the number of positive allergen-specific IgEs in each patient was 3.0 ± 1.6. The top 3 common inhaled allergens in patients with eczema/dermatitis were Dermatophagoides farinae (904/1 522, 59%) , Dermatophagoides pteronyssinus (891/1 513, 59%) and Alternaria alternata (206/1 068, 19%) , and the top 3 common food allergens were shrimps (251/1 432, 18%) , egg white (165/992, 17%) and cow milk (149/994, 15%) . Among the 3 051 patients, 25 (1%) were aged < 2 years, 571 (19%) aged 2 - 12 years, 285 (9%) aged 12 - 18 years, and 2 170 (71%) were aged > 18 years. The most common food allergens were both egg white in the age groups of < 2 years and 2 -12 years (77%, 37%, respectively) , and were both shrimps in the age groups of 12 - 18 years and > 18 years (31%, 17%, respectively) . Dermatophagoides pteronyssinus and Dermatophagoides farina were the top 2 common inhaled allergens in all age groups, with the positive rate ranging from 36% to 84%; in addition, the positive rate of molds was relatively high in the age group of 2 - 12 years (mold mixture: 37%; Alternaria alternata: 27%) . From April 2021 to March 2022, the positive rate of outdoor allergens ranged from 10% to 15% among outpatients in every month; the positive rates of tree pollen and grass pollen increased from April 2021, and peaked in October 2021. The patients with atopic dermatitis showed a significantly increased positive rate of allergens (73%) compared with those with other eczema/dermatitis (37%, χ2 = 389.36, P<0.001) , and the rank of common allergens in the patients with atopic dermatitis was basically the same as that in those with eczema/dermatitis. Conclusions:The common allergens were Dermatophagoides farina, Dermatophagoides pteronyssinus and Alternaria alternata in the patients with eczema/dermatitis. Food allergy was more common in infant patients, and inhalation allergy was more common in child, adolescent and adult patients. The positive rate of allergen-specific IgEs was markedly higher in the patients with atopic dermatitis than in those with other eczema/dermatitis.

【Objective】 To investigate the risk factors and predictive effectiveness of prostate imaging reporting and data system (PI-RADS) score for patients with clinically significant prostate cancer (CsPCa) whose PI-RADS score was 3, so as to provide evidence for the diagnosis and treatment. 【Methods】 The clinical and multi-parameter magnetic resonance imaging (mpMRI) data of 153 CsPCa patients treated during Jan.2017 and Dec.2021 whose PI-RADS score was 3 were retrospectively analyzed. With PI-RADS score of 3 as the independent risk factor for CsPCa, the other relevant independent risk factors in predicting CsPCa were evaluated. 【Results】 Univariate and multivariate analyses showed that prostate-specific antigen (PSA) density and apparent dispersion coefficient (ADC) were independent risk factors for the diagnosis of CsPCa (P<0.05). Analysis of receiver operating characteristic (ROC) curve showed that combined PSA density and ADC were more effective than PSA density and ADC alone (P<0.05). 【Conclusion】 The combination of PSA density and ADC can guide clinicians to identify high-risk CsPCa patients from patients with PI-RADS score of 3 points.

OBJECTIVE: To investigate the characteristics of cognitive impairment in critical patients, and to explore the role of early cognitive intervention training in improving cognitive impairment in critical patients. METHODS: A prospective cohort study was conducted. 133 patients in conscious and normal intelligence admitted to intensive care unit (ICU) of Hefei Second People's Hospital from January 2015 to June 2018 were enrolled. The patients were divided into control group (n = 66) and cognitive intervention group (n = 67) according to random number table based on chronological number for entry into the study. Cognitive function was assessed by Montreal cognitive assessment scale (MoCA scale) within 24 hours after ICU admission. The patients in the cognitive intervention group received a series of scientifically designed cognitive training sessions (playing electronic musical keyboard, learning simple Spanish, clock-drawing, psychological intervention) for 2 months, and follow-up was completed if the patient was discharged from ICU. While the patients in the control group did not undertake any cognitive training. After 2 months, the cognitive function of patients in both groups were assessed with MoCA scale. Subgroup analysis was conducted according to different age groups (20-40 years old, 41-60 years old, 61-80 years old) to explore the effect of cognitive intervention training in different age groups. According to the subjective evaluation of the patient's ability to live 2 months after cognitive intervention by the patient or his relatives, receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of the total score of MoCA for patients' ability to live after cognitive intervention. RESULTS: 133 critical patients were enrolled in the final analysis. There was no significant difference in gender, age, education, complications, ICU hospitalization, sedative or analgesic drug usage between the two groups, indicating that the data of the two groups were balanced and comparable. No significant difference in MoCA scale total score or sub-item cognitive domain score within 24 hours of ICU admission was found between the two groups. After 2 months of intervention, the incidence of cognitive impairment in the cognitive intervention group was significantly lower than that in the control group [38.8% (26/67) vs. 60.6% (40/66), χ² = 6.321, P = 0.015]. The total score of MoCA scale and four sub-item cognitive domain scores including visual space and execution power, protection of memory, attention execution, and orientation in the cognitive intervention group were significant higher than those in the control group (MoCA scale total score: 26.73±1.92 vs. 24.95±2.26, visual space and executive power score: 4.39±0.70 vs. 3.95±0.88, protection of memory score: 8.91±1.03 vs. 8.24±1.37, attention execution score: 5.21±0.77 vs. 4.79±1.00, orientation score: 5.67±0.53 vs. 5.44±0.68, all P < 0.05), but no significant difference was found in verbal skills score (2.55±0.56 vs. 2.53±0.56, P > 0.05). Subgroup analysis showed that the total MoCA scale score of the younger sample (20-40 years old, n = 20) was recovered by 2.10±1.55 in the cognitive intervention group after 2 months of cognitive intervention, which was significantly higher than that in the control group (n = 21; 0.24±2.76, P < 0.05). In the middle-aged and the older population [aged 41-60 years old (n = 20) and 61-80 years old (n = 27)], the total MoCA scale scores were recovered slightly after cognitive intervention as compared with those in the younger sample (0.43±1.47, -1.91±2.20 vs. 2.10±1.55, both P < 0.05), which were significantly lower than those in the control group [aged 41-60 years old (n = 21) and 61-80 years old (n = 24), -0.78±1.38, -4.41±2.17, both P < 0.01]. It was suggested that cognitive intervention training played an active role in the recovery of cognitive function in young critical patients. It was shown by ROC curve analysis that the area under ROC curve (AUC) of MoCA scale total score for predicting daily life ability after cognitive intervention was 0.732 with 95% confidence interval (95%CI) of 0.646-0.819. When the best cut-off value was 24.5, the sensitivity was 89.3%, the specificity was 60.2%, the positive predictive value was 85.7%, and the negative predictive value was 80.8%. CONCLUSIONS Early cognitive intervention could efficiently abate the deterioration of cognitive function in critical patients in ICU and had significant effects on the visual space and executive power, protection of memory, attention execution and orientation. Cognitive intervention exerted significantly positive effects on the recovery of cognitive function in the younger sample population (aged 20-40 years old).

Background and purpose:To perform whole mount technique in the diagnosis of the prostate cancer could provide orientation to the specimen. Whole mount technique has great value in pathologic diagnosis and morphological research. However, limited by the specimen-making technique, shortage of equipment and heavy workload, this technique has not been generally accepted in China. The aim of this study was to evaluate the signiifcance of whole mount technique in the diagnosis of the prostate cancer by comparing the clinical and pathological variables between whole mount patients and conventional ones after radical prostatectomy (RP).Methods:A total number of 229 patients’ whole mount RP specimens were recruited in the study from Dec. 2012 to Feb. 2014. The control group included 393 patients’ specimens which underwent conventional sampling from Jan. 2010 to Jun. 2012. We compared the clinical and pathological variables between the groups, including age, preoperative PSA level, methods of diagnosis, preliminary diagnostic Gleason score, clinical T stage, postoperative Gleason score, pathological T stage, positive surgical margin, extraprostatic extension, seminal vesicle invasion and pelvic lymph node metastasis.Results:Two groups shared similar preoperative parameters. Also there was no signiifcant difference between the whole mount and the conventional sampling groups in postoperative Gleason score, pathological T stage, extraprostatic extension and pelvic lymph node metastasis. However, positive surgical margin and seminal vesicle invasion rates were much higher in the whole mount group than the control one and both of the differences reached statistical signiifcance (26.2%vs 17.6%, 23.1%vs 17.0%;P=0.010, 0.025)Conclusion:After compared the clinical and pathological variables, we could conclude that whole mount technique has prevalence in the diagnosis of the positive surgical margin and seminal vesicle invasion compared with the conventional sampling technique. Thus, whole mount technique should be strongly recommended in the diagnosis of prostate cancer.

Objective To explore the inhibitory effect of Oldenlandia diffusa extract on colorectal cancer angiogenesis in BALB/c mice. Methods Thirty-two BALB/c mice with subcutaneous CT26 colon cancer animal model were randomly equally divided into four groups,including the control group (groupⅠ,saline 0.1 mL/(10. d), O. diffusa ethanol extract of 90 mg/(kg.d) (groupⅡ), O. diffusa ethanol extract of 180 mg/(kg.d) (groupⅢ) and O. diffusa ethanol extract of 360 mg/(kg.d) (group Ⅳ) . Each group of mice were treated with intragastric administration of law administration 12 days after vaccination, then stopped and continue fed to 32 days, and the mice were killed. Micro-vascular dense ( MVD) was observed and countered under the microscopy by immunohistory chemistry. Results The murine colon tumor volumes of GroupⅡ,ⅢandⅣwere significantly less than that of groupⅠ,with significant difference ( <0.05) . The tumor microvessel density values of four groups was (7.83±2.87), (5.32±1.27), (1.77±0.70) and (1.87±0.68),respectively. The number of tumor blood vessels in GroupⅡ,Ⅲ and Ⅳ were significantly less than that of Ⅰ group, with significant difference ( <0.05) . Conclusion Within a certain dose range, the ethanol extract of O. diffusa can significantly inhibit the mouse colon cancer and the mechanism may be realated to inhibiting tumor angiogenesis.

Objective To explore the inhibitory effect of the ethanol extract of Oldenlandia diffusa on the proliferation of CT-26 colon cancer cells which come from BALB/c mice. Method We determined the inhibitory effect of different concentrations of ethanol extract of Oldenlandia diffusa on CT-26 cells' proliferation by using methyl thiazolyl tetrazolium (MTT), and calculated the 50% inhibiting concentration (IC50) . Results As to the same concentration, the inhibitory effect of the ethanol extract of Oldenlandia diffusa on CT-26 cells was increased with time, for exsample:after treated with 0.08 mg/mL of ethanol extract of Oldenlandia diffusa for 24 h, 48 h and 72 h, the inhibitory rates of CT-26 cells were (16.67 ±9.35)%, (34.66 ±9.23)%and (40.07 ±9.16)%, respectively. After treating CT-26 cancer cells for 24 h, 48 h and 72 h, the IC50 values of the ethanol extract of Oldenlandia diffusa were 0.315,0.155 and 0.115 mg/mL, respectively. In the same treatment time, the inhibitory effect of the ethanol extract of Oldenlandia diffusa on CT-26 cells was increased with the increase of concentration:after treatment for 72 h with different concentrations (0.06 mg/mL,0.08 mg/mL,0.10 mg/mL,0.12 mg/mL, 0.14 mg/mL,0.16 mg/mL,0.18 mg/mL and 0.20 mg/mL) of the ethanol extract of Oldenlandia diffusa,the inhibitory rates of CT-26 cells were (35.46 ±3.59)%, (40.07 ±9.16)%, (40.77 ±6.92)%, (52.81 ±1.87)%, (54.22±2.35)%, (68.72±3.71)%, (70.04±8.03)%and (71.84±3.12)%, respectively. Conclusion The ethanol extract of olenlandia diffusa can inhibit the proliferation of CT-26 colon cancer cells from BALB/c mice in a time and dose dependent manner.
