Objective:To construct a predict model based on ultrasomics parameters that can identify moderate acute hypoxemic respiratory failure patients at risk of non-invasive respiratory strategies(NIRS) failure and evaluate its value.Methods:This is a prospective observational trial.The patients with moderate acute respiratory failure (100 mmHg≤PaO 2/FiO 2≤200 mmHg) in intensive care unit(ICU) ,emergency and respiratory ward of Changshu Hospital Affiliated to Soochow University from Oct 2020 to Jan 2023 were included, NIRS failure is defined as death or intubation while on therapy.At admission time and 24 h after treatment vital signs,biological and ultrasound parameters were determined.The study subjects were randomly ( random number) divided into a development group (70%) and a validation group (30%).Univariate and multivariate logistic regression was performed.The treatment failure prediction models were constructed according to ultrasonic parameters combined with clinical parameters.The models were also validated by ROC curves, calibration curves, NRI index and decision curve analysis (DCA).The nomograms were drawn. Results:A total of 193 patients were included in the study, 137 were allocated to the development group, and 56 to the validation group, there was no statistically significant difference between the two groups. NIRS failed in 112 (58%) of 193 patients..Univariate analysis revealed that PaO 2/FiO 2, DE at the time of admission and 24 h in the failure group were found to be statistically lower than the success group, RV/LV was higher (all P<0.05). RR, LUS at 24 h in the failure group were higher and ROX index was lower (all P<0.01). In addition, more patients in the failure group received vasopressors ( P= 0.001). Use of vasopressors( OR=4.709, P=0.012), RR( OR=1.254, P=0.035), LUS( OR=1.250, P=0.037), RV/LV( OR=1.057, P=0.008), PaO 2/FiO 2 ( OR=0.950, P=0.001), DE ( OR=0.107, P=0.001) in the development group were independent risk factors for NIRS failure.ROC analysis revealed that model B achieved a larger area under curve (AUC) than model A in the development group, with their AUC values of 0.928 and 0.872 ( P=0.009), AUC of model A and model B in the validation group were 0.867 and 0.932 respectively ( P=0.07).Two prediction models showed a good degree of calibration (all P>0.05). NRI analysis showed significant improvement in the predictive power of model B ( P<0.01). DCA showed that the model B had a good net benefit between the threshold probabilities of 0-80%. Conclusions:Ultrasomics parameters combined with Clinical parameters can effectively predict NIRS failure in moderate acute hypoxemic respiratory failure patients.

Objective:To evaluate the effect of high-flow nasal cannula (HFNC) therapy on patients with moderate acute respiratory failure.Methods:This was a randomized controlled trial. The patients with moderate acute respiratory failure in the Intensive Care Unit (ICU) of Changshu Hospital Affiliated to Soochow University from March 2019 to September 2020 were included. Patients with severe asthma or acute exacerbation of chronic respiratory failure, hemodynamic instability, disturbance of consciousness, non-invasive ventilation (NIV) contraindication, urgent need for endotracheal intubation, refusal of intubation, age <18 years and pregnancy were excluded. The patients were randomized to HFNC or NIV. Treatment failure was defined as the need for intubation and invasive ventilation. The vital signs, ROX index, blood gas analysis index, ultrasound parameters and endotracheal intubation rate were recorded at 1, 6, 12, 24 and 48 h after treatment. Kaplan-Meier method was used to draw the survival curve, and multivariate logistic regression was used to analyze the risk factors of treatment failure.Results:A total of 91 patients were included in the study, including 46 patients in the HFNC group and 45 patients in the NIV group. PaO 2/FiO 2 of the two groups were significantly increased after treatment compared with baseline ( P<0.05). The respiratory rate was lower in the NIV group than in the HFNC group at 1 and 24 h ( P<0.05). There were no significant differences in other vital signs, arterial blood gas and ultrasound parameters between the two groups (all P>0.05). The intubation rate was 52.2% in the HFNC group and 48.9% in the NIV group. Kaplan-Meier survival analysis showed that there was no significant difference in intubation rate and mortality between the two groups ( P>0.05). Multivariate logistic regression analysis showed that increased end-diastolic right ventricle/left ventricle ratio ( OR=1.044, 95% CI: 1.012~1.077) and high acute physiology and chronic health evaluationⅡ score ( OR=1.082, 95% CI: 1.006~1.163) at 0 h, lung ultrasound score ( OR=1.353, 95% CI: 1.034~1.772) and end-diastolic RV/LV ratio ( OR=1.097, 95% CI: 1.038~1.159) at 1 h were independent risk factors for non-invasive respiratory strategies failure. Increased diaphragm excursion ( OR=0.341, 95% CI: 0.165~0.704) at 0 h, high PaO 2/FiO 2 ( OR=0.929, 95% CI: 0.884~0.977), increased ROX index ( OR=0.524, 95% CI: 0.332~0.826), and increased diaphragm mobility ( OR=0.119, 95% CI: 0.030~0.476) at 1 h were independent protective factor for successful treatment. Conclusions:HFNC and NIV can improve oxygenation in patients with acute hypoxemic respiratory failure. There is no significant difference in intubation rate and mortality between HFNC and NIV. Ultrasound parameters may be helpful for predicting treatment failure.

Objective:To develop a prediction model of acute gastrointestinal injury (AGI) grading combined with qSOFA score for the diagnosis of sepsis, and evaluate its value.Methods:This was a prospective observational study. The patients with infection or suspected infection in the General Ward of Changshu Hospital Affiliated to Soochow University from September 2018 to September 2019 were included. Patients younger than 18 years, pregnant, abandoned treatment and died within 3 days after admission were excluded. Clinical characteristics, laboratory test results and AGI grading from 48 h before the infection to 24 h after the onset of infection were recorded. The patients were divided into the sepsis and non-sepsis groups according to whether they were diagnosed with sepsis. The patients were allocated randomly to a modeling cohort and a validation cohort with a ratio of 7:3. Univariate and multivariate logistic regression analyses were used to analyze the relevant risk factors for sepsis in the modeling cohort. Three types of diagnostic models were constructed in the modeling cohort: model A (qSOFA model), model B (the combined model of AGI grading and qSOFA score), and model C (the combined model of clinical parameters). The clinical usefulness of the diagnostic models was assessed by receiver operating characteristic curve (ROC), calibration curve and decision curve analysis (DCA) in the validation cohort. The nomograms were developed based on these models.Results:A total of 2 553 patients were enrolled in the study, 1 789 patients in the modeling cohort and 764 patients in the validation cohort. and 326 were diagnosed with sepsis. There was no statistical difference in the basic conditions of patients in the two groups. Univariate analysis showed that age, gender, the source of infection, temperature, heart rate, polypnea, changes in consciousness, severe edema, hyperglycemia, white blood cell, C-reactive protein and procalcitonin, hypotension, hypoxemia, acute oliguria, coagulation disorders, hyperlacticemia, capillary filling damage or piebaldskin, AGI grading and qSOFA score were significantly correlated with sepsis (all P<0.01). Multivariate logistic regression analysis showed that age ( OR=1.027, P<0.01), source of infection ( OR=2.809, P=0.03), hypotension ( OR=35.449, P<0.01), hypoxemia ( OR=57.018, P<0.01), and AGI grading ( OR=19.313, P<0.01) were significantly associated with sepsis. ROC analysis showed that the area under the curve (AUC) of model A, B and C were 0.784, 0.944 and 0.971 in the modeling cohort, and 0.832, 0.975 and 0.980 in the validation cohort, respectively. The sensitivities were 63.9%, 89.5% and 97.5% in the modeling cohort, and 72.7%, 90.9% and 96.6% in the validation cohort; and the specificities were 90.8%, 90.3% and 88.1% in the modeling cohort, and 92.2%, 94.5% and 92.8% in the validation cohort, respectively. AUC of model B and C were significantly higher than that of model A ( P<0.01). Model A in the validation cohort was poorly calibrated, with low accuracy and high risk of missed sepsis diagnosis ( P=0.044). The net benefits of model B and C were better than that of model A. Conclusions:AGI grading combined with qSOFA score has a high predictive value and accuracy in the diagnosis of sepsis.

Objective: To evaluate the long-term outcome of patients with hypertrophic obstructive cardiomyopathy(HOCM) after percutaneous transluminal septal ablation(PTSMA). Methods: HOCM patients who underwent PTSMA and surgical myectomy at the Chest Hospital of Shanghai Jiao Tong University from April 2001 to February 2019 were included in this retrospective analysis. Patients were divided into PTSMA group and surgical myectomy group. In addition, patients undergoing PTSMA were further divided into HOCM-PTSMA non-survivor group and HOCM-PTSMA survivor group. The general clinical information, procedural/surgical information and complications during hospitalization were compared between groups. Multivariate Cox regression model was used to analyze the independent risk factors for all-cause death in HOCM patients after PTSMA. Results: A total of 104 patients with HOCM who underwent PTSMA were enrolled. Mean age of the patients was (54±15) years old, including 41 females (38.7%). The follow-up time was 37.5(14.3, 76.8) months. At the last follow-up, 12 patients died (HOCM-PTSMA non-survivor group) and 92 were alive(HOCM-PTSMA survivor group). The proportion of patients with NYHA function class Ⅲ/Ⅳ was higher(P=0.036), and the posterior wall of the left ventricle was thicker(P=0.006) in the HOCM-PTSMA non-survivor group than in the HOCM-PTSMA survivor group. The immediate success rate of PTSMA in this cohort was 66%(70/104). The amount of absolute alcohol during the operation in the HOCM-PTSMA non-survivor group was (2.9±0.8) ml, which tended to be higher as compared to that in the HOCM-PTSMA survivor group((2.4±1.0)ml, P=0.056). Kaplan-Meier survival curve analysis showed that patients with HOCM who underwent PTSMA had an all-cause mortality-free survival rate of 90.1%, 78.3%, and 56.9% at 5, 10 and 15 years, and a HOCM-free survival rate of 91.3%, 79.4% and 57.7% at 5, 10 and 15 years, respectively. Multivariate Cox regression analysis showed that age≥ 65 years was an independent risk factor for all-cause death after PTSMA in patients with HOCM (HR=2.697, 95%CI 1.292-18.977, P=0.020). There were 32 patients in the surgical myectomy group. The proportion of patients with NYHA function class Ⅲ/Ⅳ was higher than that in the PTSMA group(P<0.001), while age, gender, and major comorbidities(atrial fibrillation, coronary heart disease, hypertension, and diabetes) as well as the left atrium dimension were all similar between the two groups(all P>0.05). Patients in the surgical myectomy group were followed up for 38.0(17.6, 64.2)months, and no deaths occurred during the follow-up period. Kaplan-Meier survival curve analysis showed that there were no statistically significant differences in all-cause-free and HOCM-free survival rates between patients in PTSMA group and surgical myectomy group(P=0.089 and 0.110, respectively). Conclusion: PTSMA is safe and effective for the treatment of patients with HOCM, and the long-term survival rate of patients after PTSMA is similar as patients undergoing classical surgical myectomy surgery.

BACKGROUND: Until now, there are no reliable methods for the treatment of urinary incontinence after radical prostatectomy. Some limitations exist in drug therapy, mid-urethral suspension, and filling agent treatment. Therefore, the use of autologous adipose-derived stem cells (ADSCs) is expected to become a first-line treatment strategy for urinary incontinence after radical prostatectomy. OBJECTIVE: To report our initial experience with transurethral injection of autologous ADSCs for the treatment of urinary incontinence after radical prostatectomy. METHODS: Patients and their families were informed of possible risks and benefits prior to the participation in the trial. After providing written informed consent, six patients with persistent urinary incontinence after radical prostatectomy were enrolled in the study. Under general anesthesia, about 50 mL of adipose tissue was obtained from each patient by liposuction. ADSCs were obtained by separation with centrifugation using the Celution cell-processing device. A mixture of ADSCs and adipose tissue was transurethrally injected into the submucosal space of the membranous urethra. Functional and anatomical improvement was assessed through a 24-hour pad test, validated patient questionnaire, urethral pressure profile, and magnetic resonance imaging (MRI) through 12-week follow-up. RESULTS AND CONCLUSION: Urine leakage volume was improved with time in all patients in the 24-hour pad test, with the exemption of temporal deterioration in two patients at the first 2 weeks post-injection. Subjective symptoms and quality of life assessed on the basis of questionnaire results showed similar improvement. The mean maximum urethral closing pressure increased from 4.312 kPa to 6.223 kPa at 12 weeks after cell injection. MRI results showed an increase in functional profile length (from 6.1 to 8.3 mm) between the lower rim of the pubic bone and the bladder neck. Adverse events, such as pelvic pain, inflammation, or de novo urgency, were undetected in any case during the follow-up. To conclude, the transurethral injection of autologous ADSCs can be a safe and effective treatment for urinary incontinence after radical prostatectomy.

Objective To explore the therapeutic effect of combining continuous venovenous hemofiltration (CVVH) with hemoperfusion (HP) on patients with septic shock.Methods A prospective study was conducted. Thirty-two patients with septic shock admitted to Changshu No.1 People's Hospital were enrolled, and they were divided into two groups according to random digits table. The observation group (17 cases) was given HP before CVVH, in the control group (15 cases), only CVVH treatment was carried out, and lasting for 5 days in both groups. The changes of pulse oxygen saturation (SpO2), central venous pressure (CVP), systemic vascular resistance index (SVRI), cardiac index (CI), extra-vascular lung water index (EVLWI) were observed before treatment and 5 days after treatment.Results Compared with those before treatment, the levels of SpO2, CVP, SVRI, CI were obviously elevated, and EVLWI was markedly decreased after treatment in two groups. Compared with those of control group, the degrees of improvement of above indicators in observation group were more prominent [SpO2: 0.966±0.035 vs. 0.939±0.036, CVP (mmHg, 1 mmHg = 0.133 kPa): 8.5±3.2 vs. 8.1±4.2, SVRI (kPa·s·L-1·m-2): 1 497.35±157.08 vs. 1 343.60±144.48, CI (mL·s-1·m-2): 120.36±15.34 vs. 106.69±12.33, EVLWI (mL/kg): 6.84±0.73 vs. 7.65±0.70, allP < 0.05].Conclusion Combing HP with CVVH for treatment of patients with septic shock can improve their prognosis more obviously than using CVVH alone.
Résumé
A total of 24 biologically pure entophytic fungal strains were isolated from stems, leaves, and seed coats of Xylocarpus plants by repeated purification, and identified with Internal Transcribed Spacer (ITS) rDNA molecular method, which belonging to 14 genera, 11 families, 9 orders and 3 classes. There were differences in genus and species levels among three plant materials from different habitats and species, and it was found that the strains of Phomopsis and Colletotrichum existed in all three plant materials. In vitro assay of antitumor activity by MTT method revealed that the EtOAc extracts of 15 strains exhibited potent antitumor activity. These results suggest that it is of value for further investigation on the above fungal strains.

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of selective serotonin re-uptake inhibitors (SSRIs) in the treatment of premature ejaculation (PE).</p><p><b>METHODS</b>From MEDLINE (Jan, 1950-Mar, 2008), EMBASE (Jan, 1980-Mar, 2008), The Cochrane Library (Issue 1, 2008) and CNKI (Jan, 1979-Mar, 2008), we retrieved and screened the randomized controlled trials (RCT) and randomized crossover trials (RT) as well as various related data, published and unpublished, on the treatment of PE with SSRIs. The methodological quality of the included trials was evaluated by 2 reviewers. Meta-analyses were conducted with RevMan 5.0 on the homogeneous studies.</p><p><b>RESULTS</b>Totally 22 studies on 4 291 patients were included. Meta-analyses showed that after treated with sertraline, fluoxetine, paroxetine, citalopram, dapoxetine and fluvoxamine, the WMD (95% CI) values of the changes in intravaginal ejaculatory latency time (IELT) were 2.63 (1.80, 3.46), 2.21 (1.50, 2.92), 4.31 (2.71, 5.91), 3.82 (3.39, 4.25), 1.57 (1.31, 1.84) and 0.01 (0.71, 0.73) respectively; the RR (95% CI) values of the sexual satisfaction rate of the patients were 1.65 (1.12, 2.43), 2.93 (0.50, 17.31), 3.08 (2.27, 4.17), 2.48 (1.99, 3.09) and 2.93 (2.36, 3.65), and those of their partners were 1.47 (0.98, 2.21), 2.88 (0.38, 21.77), 4.81 (3.15, 7.36), 5.38 (3.75, 7.72) and 2.91 (1.09, 7.78) respectively for sertraline, fluoxetine, paroxetine, citalopram and dapoxetine.</p><p><b>CONCLUSION</b>All the known SSRIs but fluvoxamine could prolong IELT, and some could improve the sexual satisfaction of both the patients and their partners, but their adverse effects should be noted. The moderate possibility of selection bias and publication bias in the included studies might have a negative impact on the evidence intensity of our results. We expect more reliable evidence from more randomized controlled trials.</p>
