Effects of preoperative mTOR inhibitors on partial nephrectomy for renal angiomyolipoma associated with tuberous sclerosis complex / 中华泌尿外科杂志

Objective:To investigate the effects of preoperative mammalian target of rapamycin(mTOR )inhibitor on partial nephrectomy for renal angiomyolipoma associated with tuberous sclerosis complex (TSC-RAML).Methods:A retrospective analysis was conducted on clinical data from 13 patients who were diagnosed with TSC-RAML and treated at Peking Union Medical College Hospital between August 2019 and July 2022. This cohort included 4 males and 9 females, with ages ranging from 22 to 66 years. All patients underwent partial nephrectomy, with 2 patients requiring two-stage surgeries due to bilateral RAMLs, resulting in a total of 15 surgeries being performed. Preoperative mTOR inhibitors, specifically everolimus (10 mg/d) or sirolimus (2 mg/d), were administered orally for at least 3 months prior to 7 of the surgeries. The effects of mTOR inhibitors on tumor size, tumor computed tomography attenuation value (CT value), and tumor CT enhancement were evaluated. The comparison of surgery-related clinical parameters was conducted between patients who received preoperative mTOR inhibitors and those who did not to assess the influences of mTOR inhibitors on surgery.Results:Compared to the baseline tumor, there was a significant reduction in tumor diameter after mTOR treatment [(6.4±3.1) cm vs. (8.7±3.9)cm], as well as in the CT value in both the unenhanced phase[(-18.63±48.73)HU vs. (-2.13±51.58)HU] and corticomedullary phase[(13.25±64.01)HU vs. (47.25±66.99)HU]. Additionally, tumor CT enhancement also decreased as compared with that before treatment [(31.88±18.20)HU vs. (49.38±20.63)HU]. Patients who received preoperative mTOR inhibitor showed a trend towards shorter operative time for removing per milliliter of tumor compared to those without preoperative mTOR inhibitor [1.06(0.18, 2.40) min/ml vs. 1.98(0.39, 5.03) min/ml] and so was the renal artery clamping time [0.17(0.03, 0.79) min/ml vs. 0.34(0.10, 1.71) min/ml]. Additionally, the amount of intraoperative bleeding for removing per milliliter of tumor was lower in patients with preoperative mTOR inhibitors compared to those without [0.72(0.19, 0.88) ml/ml vs. 1.69(0.59, 4.54) ml/ml].Conclusions:The administration of mTOR inhibitors before partial nephrectomy in patients with TSC-RAM have the potential to reduce tumor size and blood supply, as well as operative time, renal artery clamping time and intraoperative bleeding, which might contribute to surgery safety and preservation of renal function.

The predictive effect of adjusted Utrecht staging criteria on efficacy of mTOR inhibitors in TSC-AML patients / 中华泌尿外科杂志

Objective:To investigate the predictive effect of adjusted Utrecht staging criteria on efficacy of mammalian target of rapamycin (mTOR) inhibitors in patients with tuberous sclerosis-associated renal angiomyolipoma (TSC-AML).Methods:In this study, 39 adult patients with TSC-AML who attended the Peking Union Medical College Hospital from December, 2014 to December, 2020 were retrospectively analyzed, and were divided into 4 groups based on Utrecht staging criteria: Group 1, Utrecht staging ≤ stage 5, all AMLs <5 cm( n=6); Group 2, stage 6 with at least one AML ≥5 cm and normal renal anatomy( n=14); Group 3, stage 6 with at least one AML ≥5 cm and recognizable renal anatomy( n=10); Group 4, stage with at least one AML ≥5 cm and unrecognizable renal anatomy ( n=9). The mean age of patients in the 4 groups were 27.33±7.84, 28.64±12.36, 31.10±5.88 and 29.11±7.15 ( P=0.869). No statistic difference in gender was found among the different groups ( P=0.233). The mean maximum diameters of AML in the four groups were (3.54±0.52)cm, (8.11±2.08)cm, (11.58±4.60)cm and (17.08±3.61)cm, respectively( P<0.01). The mean levels of creatinine were (80.17±16.01)μmol/L, (76.36±18.72)μmol/L, (76.10±27.61)μmol/L and (71.89±18.66)μmol/L in the four groups( P=0.900). The numbers of patients with positive urine protein were 2, 3, 8 and 2 ( P=0.023). All the patients took Everolimus 10mg orally per day for at least 3 months. Differences in maximum AML shrinkage rate, creatinine level, severity of urine protein and microscopic hematuria were compared between the groups. Results:As AML severity increased, the shrinkage rates decreased significantly in turn [Group 1: (76.06±13.16)%, Group 2: (64.92±16.33)%, Group 3: (55.30±20.49)%, Group 4: (43.73±20.61)%, P=0.009]. After treatment, creatinine levels increased in all groups[Group 1: (8.50±7.61)μmol/L, Group 2: (5.71±8.54)μmol/L, Group 3: (7.70±7.18)μmol/L, Group 4: (6.11±7.04)μmol/L], but there was no significant difference among groups (P=0.856). Moreover the increase in urine protein worsened with the degree of severity (Group 1∶3, Group 2∶4, Group 3∶6, Group 4∶9, P=0.014). Conclusions:The adjusted Utrecht staging criteria could predict the maximum AML shrinkage rate and urine protein increase in TSC-AML patients with treatment of mTOR inhibitors.

The risk of Alzheimer′s disease transmitted by blood transfusion based on APP/PS1 double transgenic mice / 中国输血杂志

【Objective】 To explore the risk of Alzheimer′s disease (AD) transmitted by blood transfusion. 【Methods】 There were 10 APP/PS1 mice of 3, 6 and 9 months old, half female and half male, and the cognitive and behavioral abilities of C57 mice of the same age were measured, and the blood of the oldest APP/PS1 mice with no behavioral changes were collected to detect the contents of Aβ40 and Aβ42. The polymers Aβ40 and Aβ42 were prepared and Western blotting analysis was conducted. Kunming mice aged from 6 to 7 months were randomly divided into 6 groups (10 mice/ group, half male and half female). The blood of APP/PS1 mice was injected intravenously in experimental group 1-2(100 μL/mouse) with high frequency injection (3 times/week) and low frequency injection (1 time/week), respectively. In experimental group 3-4, Aβ40 and Aβ42 polymerized mixture (100 μL/mouse) were injected in high frequency and low frequency, respectively. The control group 1-2 was injected with the same amount of normal saline, with high frequency and low frequency, respectively. The above groups were injected for 4 weeks, and the cognitive and behavioral abilities were tested and analyzed one week after injection. Finally, the contents of Aβ40 and Aβ42 in blood of Kunming mice were detected. 【Results】 Change in cognitive and behavioral ability showed in 9 months old APP/PS1 mice, but not in 3 and 6 months old APP/PS1 mice. The contents of Aβ40 and Aβ42 (pg/mL) in blood of 6-7 months old APP/PS1 mice were 418.40±2.18 and 15.68±0.20, respectively. Except for monomers, most of the polymerized mixtures of Aβ40 and Aβ42 were dimers and trimers. In both high frequency and low frequency, Kunming mice transfused with blood of APP/PS1 mice (experimental group 1-2) showed a certain degree of anxiety-like behavior and short-term memory shortening in open-field test and conditioned fear test, but without significant difference. There was no significant difference in open field test, new object recognition, Barnes maze and cognitive behavior analysis of conditioned fear between experimental group 3-4 and the control group. The levels of blood Aβ40 and Aβ42(pg/mL) of Kunming mice detected by ELISA were 10.30±0.08 and 3.360±0.005, respectively, and there was no significant difference between the two groups. 【Conclusion】 Blood transfusion of APP/PS1 mice and the mixture of Aβ40 and Aβ42 have no significant effect on the cognitive function of healthy Kunming mice in a short time, and the risk of AD transmission is relatively low.

Feasibility of deep learning for renal artery detection in laparoscopic video / 中华泌尿外科杂志

Objective:To explore the feasibility of deep learning technology for renal artery recognition in retroperitoneal laparoscopic renal surgery videos.Methods:From January 2020 to July 2021, the video data of 87 cases of laparoscopic retroperitoneal nephrectomy, including radical nephrectomy, partial nephrectomy, and hemiurorectomy, were retrospectively analyzed. Two urological surgeons screened video clips containing renal arteries. After frame extraction, annotation, review, and proofreading, the labeled targets were divided into training set and test set by the random number table in a ratio of 4∶1. The training set was used to train the neural network model. The test set was used to test the ability of the neural network to identify the renal artery in scenes with different difficulties, which was uniformly transmitted to the YOLOv3 convolutional neural network model for training. According to the opinion of two senior doctors, the test set was divided into high, medium, and low discrimination of renal artery and surrounding tissue. High identification means a clean renal artery and a large exposed area. For middle recognition degree, the renal artery had a certain degree of blood immersion, and the exposed area was medium. Low identification means that the exposed area of the renal artery was small, often located at the edge of the lens, and the blood immersion was severe, which may lead to lens blurring. In the surgical video, the annotator annotated the renal artery truth box frame by frame. After normalization and preprocessing, all images were input into the neural network model for training. The neural network output the renal artery prediction box, and if the overlap ratio (IOU) with the true value box was higher than the set threshold, it was judged that the prediction was correct. The neural network test results of the test set were recorded, and the sensitivity and accuracy were calculated according to IOU.Results:In the training set, 1 149 targets of 13 videos had high recognition degree, 1 891 targets of 17 videos had medium recognition degree, and 349 targets of 18 videos had low recognition degree. In the test set, 267 targets in 9 videos had high recognition degree, 519 targets in 11 videos had medium recognition degree, and 349 targets in 18 videos had low recognition degree. When the IOU threshold was 0.1, the sensitivity and accuracy were 52.78% and 82.50%, respectively. When the IOU threshold was 0.5, the sensitivity and accuracy were 37.80% and 59.10%, respectively. When the IOU threshold was 0.1, the sensitivity and accuracy of high, medium and low recognition groups were 89.14% and 87.82%, 45.86% and 78.03%, 32.95%, and 76.67%, respectively. The frame rate of the YOLOv3 algorithm in real-time surgery video was ≥15 frames/second. The false detection rate and missed detection rate of neural network for renal artery identification in laparoscopic renal surgery video were 47.22% and 17.49%, respectively (IOU=0.1). The leading causes of false detection were similar tissue and reflective light. The main reasons for missed detection were image blurring, blood dipping, dark light, fascia interference, or instrument occlusion, etc.Conclusions:Deep learning-based renal artery recognition technology is feasible. It may assist the surgeon in quickly identifying and protecting the renal artery during the operation and improving the safety of surgery.

Preliminary study on the effect of IVIG with different Aβ antibody on cognitive function of Alzheimer′s disease model mice / 中国输血杂志

【Objective】 To investigate the effect of intravenous immunoglobulin(IVIG) with different Aβ antibody content on the cognitive function of Alzheimer′s disease model mice. 【Methods】 IVIG from 8 domestic blood products companies were selected. Enzyme-linked immunosorbent assay(ELISA) was used to detect the content of Aβ40/42 antibody. Three kinds of IVIG with high, middle and low Aβ42/40 antibody levels were selected to treat 3xTg-AD mice. Forty 3-month-old 3xTg-AD mice were randomly divided into 4 groups with 10 mice in each group(half male and half female). Three treat groups were intraperitoneally injected with three kinds of IVIG with 1g·kg-1 for 12 weeks(twice a week). The controls were injected with the same volume of saline. Behavioral tests were performed immediately by using the mouse behavior analysis system after a total of 24 injections. 【Results】 The concentrations of antibodies(μg/mL) against Aβ40 monomer in IVIG ranged 0.7±0.05 to 3.1±0.05, concentrations of antibodies against Aβ40 oligomer ranged 11.7±0.7 to 32.0±2.2, concentrations of antibodies against Aβ42 monomer ranged 1.8±0.1 to 27.9±0.3, and concentrations of antibodies against Aβ42 oligomeric ranged 2.3±0.1 to 49.4±2. High(IVIG-1), medium(IVIG-8) and low(IVIG-6) IVIG were selected for mice study. In the open field test, the time of four groups of mice entering the central area(s) was 0.5±0.9, 23.4±6.1(P<0.0001), 4.6±2.8 and 2.6±2.3, respectively; the number of feces(grains) was 1.6±0.7(P<0.0001), 1.2±0.4(P<0.0001), 2.4±0.5(P<0.001) and 3.8±0.8, respectively. In the novel object recognition test, the scores of exploring new objects were 71.3±29.5(P<0.05), 71.8±20.5(P<0.05), 75.9±26.9(P<0.01) and 25.6±23.7, respectively. In the Barnes maze test, the time of exploring the target hole in the IVIG-8 group was significantly longer than that in the control on the 6th day(50.3±19.3 vs 21±14.6, P<0.05) and the 13th day(58.2±20.9 vs 19.2±15.9, P<0.005), but there was no significant difference between the IVIG-1, 6 groups and the control. 【Conclusion】 There is a significant difference in the level of Aβ40/42 antibody among 8 kinds of domestic IVIG. Domestic IVIG could improve the cognitive function of 3-month-old 3xTg-AD mice after continuous intervention for 3 months. The improvement effect, however, was related to the Aβ antibody in IVIG, but not to the antibody concentration.

Simulation and Experimental Study on a Novel Biodegradable Intestinal Anastomosis Stent / 医用生物力学

Objective To design a novel biodegradable intestinal anastomosis stent and explore the relationship between pressure distance and biomechanical properties of the anastomosis, so as to provide new ideas and methods for compression anastomosis of intestinal tissues. Methods A compression anastomosis stent was designed for reconstruction of intestinal tissues, and the finite element model of compression anastomosis of intestinal tissues was established to investigate the relationship between pressurized distance (2, 1.6, 1.2, 0.8 mm) and tissue stress of the stent. The anastomosis effect of intestinal tissue under different pressurized distances was analyzed by the test of tear-off force and burst pressure. Results Biomechanical properties of the intestinal anastomosis were the best when the pressurized distance was 1.2 mm, and its maximum tensile strength reached 0.77 MPa. The tear-off force and burst pressure of tissues were (25.80±1.82) N and (12.30±0.26) kPa, respectively. The optimal intestinal anastomosis was achieved when tissues were compressed to 60% of the original thickness. Conclusions The biodegradable intestinal stent designed in this study can successfully achieve compression anastomosis of intestinal tissues, which provides theoretical references for the development and application of novel biodegradable compression anastomosis devices.

Is mild erectile dysfunction associated with severe psychological symptoms in Chinese patients with moderate-to-severe chronic prostatitis/chronic pelvic pain syndrome? / 亚洲男科学杂志(英文版)

This study aimed to assess the association between psychological disorders and erectile dysfunction (ED) in patients with different degrees of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). This was a retrospective study conducted from June 2017 to October 2019 and included 182 outpatients. Patients were interviewed using the Structured Interview on Erectile Dysfunction (SIEDY) for pathogenic quantification. The National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) and the International Index of Erectile Function-5 (IIEF-5) were used for the evaluation of CP/CPPS and ED. The Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) were used to assess anxiety symptoms and depressive symptoms. The number of patients with mild CP/CPPS and mild ED, mild CP/CPPS and moderate-to-severe ED, moderate-to-severe CP/CPPS and mild ED, and moderate-to-severe CP/CPPS and moderate-to-severe ED was 69 (37.9%), 36 (19.8%), 35 (19.2%), and 42 (23.1%), respectively. The corresponding PHQ-9 scores of the four groups were 6.22, 7.19, 10.69, and 7.71, respectively. The corresponding GAD-7 scores of the four groups were 5.26, 6.31, 8.77, and 6.36, respectively. Among patients with moderate-to-severe CP/CPPS, the PHQ-9 and GAD-7 scores of the moderate-to-severe ED group were significantly lower than those of the mild ED group (P = 0.007 and P = 0.010, respectively). The prevalence of ED and premature ejaculation (PE) in patients with moderate-to-severe CP/CPPS was significantly higher than that in patients with mild CP/CPPS (P = 0.001 and P = 0.024, respectively). Our findings proved that the severity of ED was negatively associated with psychological symptoms in outpatients with moderate-to-severe CP/CPPS.

Dynamic changes of total acid and bacterial communities during the traditional fermentation of Hong Qu glutinous rice wine

Background: Hong Qu glutinous rice wine (HQGRW) is brewed under non-aseptic fermentation conditions, so it usually has a relatively high total acid content. The aim of this study was to investigate the dynamics of the bacterial communities and total acid during the fermentation of HQGRW and elucidate the correlation between total acid and bacterial communities. Results: The results showed that the period of rapid acid increase during fermentation occurred at the early stage of fermentation. There was a negative response between total acid increase and the rate of increase in alcohol during the early fermentation stage. Bacterial community analysis using high-throughput sequencing technology was found that the dominant bacterial communities changed during the traditional fermentation of HQGRW. Both principal component analysis (PCA) and hierarchical clustering analysis revealed that there was a great difference between the bacterial communities of Hong Qu starter and those identified during the fermentation process. Furthermore, the key bacteria likely to be associated with total acid were identified by Spearman's correlation analysis. Lactobacillus, unclassified Lactobacillaceae, and Pediococcus were found, which can make significant contributions to the total acid development (| r| N 0.6 with FDR adjusted P b 0.05), establishing that these bacteria can associate closely with the total acid of rice wine. Conclusions: This was the first study to investigate the correlation between bacterial communities and total acid during the fermentation of HQGRW. These findings may be helpful in the development of a set of fermentation techniques for controlling total acid.

Changes in Cold and Hot Syndrome and Gastrointestinal Bacterial Community Structure in Mice by Intervention with Food of Different Nature / 中国结合医学杂志

OBJECTIVE@#To reveal the effect of foods with different natures on cold or hot syndrome and gastrointestinal bacterial community structure in mice.@*METHODS@#Forty-five 6-week-old male ICR Kunming mice of clean grade were divided into 5 groups, 9 per group, including the control (CK), hot nature herbs (HM), Hong Qu glutinous rice wine (RW), tea rice wine (TW), and cold nature herbs (CM) groups. Distilled water or corresponding herbs were administered to mice (0.01 mL/g body weight) in the 5 groups by gastric infusion respectively, once daily for 28 d. Appearance, behavior, and serum biochemical indicators, including 5-hydroxytryptamine (5-HT), thyroid stimulating hormone (TSH), noradrenaline (NE), cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), the hot nature index, as well as the gastrointestinal bacterial community structure were analyzed in all groups after treatment.@*RESULTS@#After supplementation for 28 d, CM and TW mice showed different degrees of cold syndrome, and HM and RW mice showed different degrees of hot syndrome. Compared with the HM and RW mice, the TSH, NE, cAMP levels and hot nature indices in the CM and TW mice were significantly decreased and 5-HT and cGMP levels were significantly increased (P<0.05). There was no obvious change in appearance or behavior in CK mice. Results of clustering analysis showed that the gastrointestinal bacterial community structures were highly similar in TW and CM mice as well as in RW and HM mice, and that they were from the same branch, respectively, when the distance was 0.02. The key microbes associated with cold syndrome were Lachnospiraceae uncultured, Lactococcus, etc., and the key microbes associated with hot syndrome were S24-7 norank, Ruminococcaceae uncultured, etc. CONCLUSION: The interventions with different nature foods could change cold or hot syndrome in mice, leading to changes in gastrointestinal bacterial community structure.

Characterization of Klebsiella pneumoniae associated with cattle infections in southwest China using multi-locus sequence typing (MLST), antibiotic resistance and virulence-associated gene profile analysis

Abstract Klebsiella pneumoniae is important human and animal pathogen that causes a wide spectrum of infections. In this study, isolates from cattle nasal swabs samples were identified by 16S rRNA, and to evaluate the antimicrobial susceptibility, virulence gene carrying levels, and multilocus sequence typing of K. pneumoniae isolates. 33 isolates of K. pneumoniae were isolated and identified in 213 nasal swabs samples, of which 12 were hypervirulent K. pneumoniae strains. Extended Spectrum Beta-Lactamases genes were found in 93.4% of the strains. Of which, TEM was the most prevalent (93.4%), followed by CTX-M and SHV were 57.6% and 39.4%, respectively. A main mutation pattern of quinoloneresistance-determining region, Thr83-Ieu and Asp87-Asn in gyrA and Ser87-Ile in parC, was detected in 33 K. pneumoniae isolates. All the isolates harbored at least two virulence factor genes, with ureA (97.0%) and wabG (91.0%) exhibiting high carriage rates in 33 K. pneumoniae isolates. MLST revealed 7 sequence types, of which 3 STs (2541, 2581 and 2844) were newly assigned. Using eBURST, ST2844 and ST2541 were assigned to new clonal complex 2844. Our study provides evidence and biological characteristics of K. pneumoniae isolates from cattle upper respiratory tract in Southwest China.

A comparison of the transnasal and transoral approaches to balloon dilatation in treating cricopharyngeal achalasia among stroke survivors / 中华物理医学与康复杂志

Objective To compare the effect of treating cricopharyngeal achalasia in stroke survivors using transnasal or transoral balloon dilatation.Methods Thirty stroke survivors with cricopharyngeal achalasia were randomly divided into a transnasal and a transoral balloon dilatation group (group N and group O),each of 15.Both groups were given routine swallowing rehabilitation training as well as the transnasal or transoral balloon dilatation.Their heart rate was monitored during the dilatation.Nasal bleeding,mucous membrane swelling and pain were also observed.Their swallowing function was evaluated using the Fujishima Ichiro swallowing efficacy score (FISE) and videofluoroscopy (VFSS) before and after the intervention.Results After the treatment,the average FISE and VFSS scores of both groups had improved significantly comnpared to before the treatment but there were no significant differences between the groups.During the treatment,the average heart rate of group O increased significantly less than that of group N.The treatment acceptance of group O was 98.2％,significantly higher than that of group N (80.1％).One case of mucosal bleeding was observed in group O,and laryngeal edema occurred significantly less often than in group N (9 cases vs.7).The average pain score was also significantly lower in group O.Conclusions Balloon dilatation facilitates swallowing among stroke survivors with cricopharyngeal achalasia.The transoral approach can help to reduce the occurrence of complications such as mucosal bleeding,laryngeal edema and pain,and has better patient acceptance.

Comparison of different kinds of combination of laparoscopic operation in treatment of acute appendicitis complicated with gallbladder stones / 中国内镜杂志

Objective To investigate the clinical effects differences of three-port and single-port invasively combination laparoscopic cholecystectomy and appendectomy in the treatment of acute appendicitis complicated with gallbladder stone. Methods 110 patients with acute appendicitis complicated with gallbladder stones from August 2012 to August 2015 were randomly divided into control group (55 patients) with three-port laparoscopic operation and observation group (55 patients) with single-port laparoscopic operation;and the clinical indexes for operation related, operation overall satisfaction score of Brown, the VAS score of depression and anxiety before and after operation and postoperative complications of both groups were compared. Results The incision length of observation group was significantly shorter than control group (P< 0.05). The operative time of observation group was significantly longer than control group (P < 0.05). The operation overall satisfaction of Brown of observation group was significantly higher than control group (P < 0.05). The VAS score of depression and anxiety after operation of observation group was significantly better than control group and before operation (P<0.05). There was no signiifcant difference in the incidence of postoperative complications between 2 groups (P < 0.05). Conclusion Compared with three-port laparoscopic operation, single-port invasively combination laparoscopic cholecystectomy and appendectomy in the treatment of acute appendicitis complicated with gallbladder stone can efifciently decrease the incision length, improve the aesthetic degree and postoperative negative emotions and not lead to increased risk of postoperative complications.
