Objective To investigate the ultrasonographic characteristics of acute Stanford type A aortic dissection (ATAAD) involving the renal arteries and their relationship with renal function. Methods Patients with ATAAD admitted to Deyang People's Hospital from February 2013 to May 2023 were selected for the study. Based on whether the renal arteries were involved in the dissection, the patients were divided into two groups: a renal artery involvement group and a renal artery non-involvement group. General data and ultrasound characteristics of the two groups were compared. Logistic regression analysis and model correction were performed to analyze the relationship between ultrasound characteristics and renal function involvement in ATAAD patients. Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of ultrasound characteristics for renal artery involvement in ATAAD patients. Additionally, patients in the renal artery involvement group were divided into normal renal function and abnormal renal function subgroups based on serum blood urea nitrogen (BUN) and serum creatinine (Scr) levels. Clinical data of the two subgroups were compared, and a log-binomial model was used to analyze the risk effects of ultrasound characteristics for abnormal renal function. Pearson correlation analysis was performed to assess the correlation between ultrasound characteristics of renal artery involvement and renal function indicators. Results A total of 163 patients were included, consisting of 106 males and 57 females, with a mean age of (50.06±10.46) years (ranging from 20 to 85 years). Significant differences in gender, Scr, and BUN were observed between the renal artery involvement group and the renal artery non-involvement group (P<0.001). Compared to the renal artery non-involvement group, the renal artery involvement group had an increased ascending aorta diameter, a greater proportion of ascending aortic dilation and poor renal perfusion (P<0.05). Logistic regression analysis indicated that ascending aorta diameter, ascending aortic dilation, and poor renal perfusion were independent factors for renal artery involvement (P<0.05). Ultrasonographic characteristics showed good predictive ability for renal artery involvement in ATAAD patients. Furthermore, the combination of the three characteristics yielded a higher predictive value for renal artery involvement. Compared to the normal renal function group, the abnormal renal function group had higher BUN and Scr levels, increased ascending aortic diameter, a greater proportion of ascending aortic dilation and poor renal perfusion (P<0.05). The log-binomial model analysis revealed that the risk ratios for ascending aortic diameter, ascending aortic dilation, and poor renal perfusion were statistically significant both before and after adjustment (P<0.05). Pearson correlation analysis revealed that ascending aortic diameter, ascending aortic dilation, and poor renal perfusion were strongly correlated with renal function parameters (P<0.05). Conclusion Ultrasound characteristics of ATAAD involving the renal arteries are associated with renal function. Ascending aorta diameter, ascending aortic dilation, and poor renal perfusion are independent risk factors for abnormal renal function.

ObjectiveTo investigate the risk factors for pyogenic liver abscess （PLA） comorbid with sepsis by analyzing clinical features， and to construct a predictive model. MethodsA retrospective analysis was performed for 489 patients who were hospitalized and diagnosed with PLA in The Affiliated Hospital of Xuzhou Medical University from January 2019 to December 2023， and according to the presence or absence of sepsis， they were divided into sepsis group with 306 patients and non-sepsis group with 183 patients. Related data were collected， including general information， laboratory markers， and outcome measures. The patients were further divided into a training set of 342 patients and a validation set of 147 patients at a ratio of 7∶3， and the training set was used for screening of variables and construction of a predictive model， while the validation set was used to test the performance of the model. An LASSO regression analysis was used for the screening of variables， and a multivariate Logistic regression analysis was used to construct the predictive model and plot a nomogram. The calibration curve， the receiver operating characteristic （ROC） curve， and the decision curve analysis were used for the validation of the model， and internal validation was performed for assessment. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical variables between groups. ResultsThere were significant differences between the sepsis group and the non-sepsis group in pulse rate， mean arterial pressure， duration pf symptoms， comorbidity of liver cirrhosis or malignant tumor， leukocyte count， neutrophil count， lymphocyte count， platelet count （PLT）， activated partial thromboplastin time， fibrinogen， C-reactive protein， aspartate aminotransferase， alanine aminotransferase， albumin， total bilirubin （TBil）， creatinine， potassium， and prognostic nutritional index （PNI） （all P<0.05）. In the training set， the LASSO regression analysis identified four predictive factors of pulse rate， PLT， TBil and PNI， and the multivariate Logistic regression analysis showed that pulse rate （odds ratio ［OR］=1.033， 95% confidence interval ［CI］： 1.006‍ ‍—‍ ‍1.061， P=0.018）， PLT （OR=0.981， 95%CI： 0.975‍ ‍—‍ ‍0.987， P<0.001）， TBil （OR=1.086， 95%CI： 1.053‍ ‍—‍ ‍1.125， P<0.001）， and PNI （OR=0.935， 95%CI： 0.882‍ ‍—‍ ‍0.988， P=0.019） were independent influencing factors for the risk of sepsis in patients with PLA. The model constructed based on these factors showed a good predictive ability， with an area under the ROC curve of 0.948 （95%CI： 0.923‍ ‍—‍ ‍0.973） in the training set and 0.912 （95%CI： 0.848‍ ‍—‍ ‍0.976） in the validation set. The decision curve analysis showed that the model has a good net benefit within the range of 0.3‍ ‍—‍ ‍0.9 for threshold probability. ConclusionThe nomogram prediction model constructed based on pulse rate， PLT， TBil， and PNI has a certain clinical value and can well predict the risk of sepsis in patients with PLA.

【Objective】 To explore the safety of transrectal ultrasound-guided transperineal injection of sodium hyaluronate to expand the Dirichlet gap in laparoscopic radical prostatectomy. 【Methods】 A total of 14 healthy male purebred beagle dogs were selected and randomly divided into 2 groups, with 7 in either group.The control group was treated with conventional laparoscopic radical prostatectomy, while the experimental group was treated with laparoscopic radical prostatectomy after 2.5 mL sodium hyaluronate was injected into the Dirichlet gap under the guidance of transrectal ultrasound.The total operation time, prostate separation time, intraoperative blood loss and rectal status of the 2 groups were observed. 【Results】 After the injection of sodium hyaluronate into the Dirichlet gap between the prostate and the rectum, no rectal tissue was found in the prostate, and no obvious damage was found in the posterior rectum in either groups.The postoperative hemoglobin (HGB) was [(118.70±2.56) g/L vs.(122.10±2.19) g/L, P=0.02]; the total operation time was [(141.40±9.80) min vs.(119.10±9.16) min, P<0.05]; the prostate separation time was [(24.99±1.75) min vs.(16.64±2.34) min, P<0.05]; the amount of bleeding was [(47.43±4.32) mL vs.(34.86±5.18) mL, P<0.05] in the control group and experimental group. 【Conclusion】 Laparoscopic radical prostatectomy performed after 2.5 mL of sodium hyaluronate injection into the Dirichlet gap under the guidance of transrectal ultrasound can shorten the total operation time, the separation and resection time of the prostate, and reduce the amount of bleeding, which can improve and reduce the incidence of rectal injury, and prove the feasibility of this approach for prostatic cancer.

Objective To compare the safety and efficacy of SpyGlass DS system laser lithotripsy and conventional fractional treatment under endoscopic retrograde cholangiopancreatography(ERCP)in treatment of large calculus of common bile duct.Method 38 patients with large calculus of common bile duct(>2 cm)during ERCP from November 2021 to October 2023 were selected and divided into experimental group(n=18)and control group(n=20).The experimental group was treated with SpyGlass DS system combined with laser lithotripsy.The patients in the control group were treated with split treatment(the first biliary stent was placed,and the calculus of common bile duct were removed under conventional ERCP again 3 months later).The success rate of stone clearance and the incidence of complications after ERCP were compared between the two groups.Magnetic resonance cholangiopancreatography(MRCP)was performed 3 months after surgery to determine whether there were residual calculus of common bile duct.Results The surgical time of the experimental group was longer than that of the control group,and the difference was statistically significant(P<0.05).There was no significant difference in the stone clearance rate and the incidence of short-term complications between the two groups(P>0.05).The incidence of long-term complications in the experimental group was lower than that in the control group,but the difference was not statistically significant(P=0.090).Conclusion SpyGlass DS guided laser lithotripsy is effective and safe for the treatment of large calculus of common bile duct,with a low recurrence rate.

Objective To compare the effect of posterior cruciate ligament retaining(CR)and posterior cruciate substituting(PS)prosthesis in knee arthroplasty.Methods 64 patients with knee osteoarthritis were admitted to our department from June 2021 to June 2022 and whom met the selection criteria were randomly selected and divided into observation group and control group(n = 32).CR prosthesis was used in the observation group,and PS prosthesis was used in the control group.Operation time,postoperative drainage volume,difference of hemoglobin(HGB)before and after operation,postoperative hospital stay,postoperative range of motion at 7 d,14 d,45 d,3 months and 1 year were recorded.ROM,visual analog pain Scale(VAS),Hospital for special surgery(HSS)score,and maximum forward and backward displacement of knee joint and the regular radiographs were also recorded,too.Results The two groups were similar in terms of operation time,postoperative hospital stay,postoperative VAS score and maximum anterior and posterior displacement of knee joint,with P values greater than 0.05,which had no statistical significance.The postoperative drainage volume in the observation group was significantly less than that in the control group,with statistical significance(P＜0.05).The HGB difference of observation group was significantly lower than that of control group,with statistical significance(P＜0.05).There was no statistically significant differ-ence in ROM and HSS scores between the two groups before surgery;the ROM and HSS scores of the control group at 7,14 and 45 days after surgery was better than that of the observation group,with statistical significance(P＜0.05);the ROM and HSS scores of the two groups at 3 months after surgery was not statistically significant.The ROM and HSS scores in the observation group was better than that in the control group at 6 months and 1 year after operation,and the difference was statistically significant(P＜0.05).Conclusions CR prosthesis is superior to PS prosthesis in terms of intraoperative blood loss and post-operative drainage volume,which can reduce surgical risk.Both kinds of prosthesis can achieve good knee stability after surgery,while PS prosthesis has better early clinical effect,while CR prosthesis has better long-term clinical effect.

Objective To analyze the epidemiological characteristics of newly reported advanced schistosomiasis cases in Sichuan Province, so as to provide the evidence for analyzing the causes and formulating targeted control measures of newly reported advanced schistosomiasis cases. Methods Individual case investigation forms for advanced schistosomiasis cases were collected from the Sichuan Provincial Epidemic Annual Report System from 2011 to 2022, and patients’ demographics, previous medical history and liver parenchymal grading were retrieved. All advanced schistosomiasis cases’ medical records were reviewed, and the subtypes of schistosomiasis-endemic villages where the cases’ household registration were, floating population, survival and death and time of death were collected. Results A total of 321 newly reported advanced schistosomiasis cases were found in Sichuan Province from 2011 to 2022, with a male to female ratio of 0.99 to 1. There were 274 cases at ages of over 50 years (85.4%), with the highest proportion seen at ages of 60 to 69 years (87 cases, 27.1%), and splenomegaly was the most common type (180 cases, 56.1%), with no dwarfism type detected. The highest number of cases was reported in 2011 (78 cases), followed by in 2022 (74 cases), and the highest number of cases were reported in Meishan City (199 cases, 62.0%), Dongpo District (131 cases, 40.8%), and hilly subtype areas (136 cases, 42.4%). As of the end of 2022, there were 111 deaths due to advanced schistosomiasis, with the highest number of deaths seen in 2018 (25 deaths), and the highest mortality was seen among patients with the ascites type (41.2%). There were 47 (37.3%), 40 (59.5%) and 4 (23.5%) cases with grade III liver parenchyma among patients with splenomegaly, ascites, and colonic proliferation types, respectively, and there was a significant difference in the grading of III liver parenchyma among three types of patients (H = 12.092, P < 0.05), with more severe liver parenchyma injuries seen among patients with the ascites type than among those with splenomegaly and colonic proliferation type (Z = 24.262 and 44.738, both P_adjusted values < 0.05). Conclusions There have been newly reported advanced schistosomiasis cases in Sichuan Province during recent years, and patients with the ascites type should be given a high priority among advanced schistosomiasis cases in Sichuan Province. Intensified clue surveys are needed for early identification and treatment of advanced schistosomiasis cases, so as to increase the survival rate and improve the quality of life.

OBJECTIVE: To compare the effectiveness of TiRobot-assisted and C-arm X-ray fluoroscopy assisted percutaneous kyphoplasty (PKP) via pedicle of vertebra in the treatment of osteoporotic vertebral compression fracture (OVCF) of thoracic vertebrae. METHODS: The clinical data of 85 patients with OVCF of thoracic vertebrae who were admitted between January 2020 and March 2023 and met the selection criteria was retrospectively analyzed including 40 patients (50 vertebrae) undergoing PKP assisted by TiRobot (group A) and 45 patients (50 vertebrae) undergoing PKP assisted by C-arm X-ray fluoroscopy (group B). There was no significant difference in the comparison of baseline data such as gender, age, body mass index, bone mineral density T-value, fracture segment, trauma history, and preoperative numerical rating scale (NRS) score, Oswestry disability index (ODI), and Cobb angle of injured vertebra between the two groups ( P>0.05). The effectiveness evaluation indexes of the two groups, including the operation time, the volume of injected cement, the times of fluoroscopies, the length of hospital stay, and the occurrence of postoperative complications were collected and compared. Anteroposterior and lateral X-ray films and CT of the injured vertebra were reviewed at 1 day after operation to observe whether there was cement leakage and to evaluate the distribution of cement in the injured vertebra. Before and after operation, pain was assessed using the NRS score, dysfunction was assessed using the ODI, and vertebral height recovery was assessed by measuring the Cobb angle of the injured vertebrae by X-ray films. RESULTS: Both groups of patients successfully completed the operation, the operation time, the volume of injected cement, the times of fluoroscopies, and the length of hospital stay in group A were significantly less than those in group B ( P<0.05). The patients in two groups were followed up 4-12 months (mean, 9.6 months). Bone cement leakage occurred in 5 vertebrae in group A and 15 vertebrae in group B after operation, all of which leaked to the intervertebral space and around the vertebral body, and the patients had no obvious clinical symptoms. The difference of bone cement leakage between the two groups was significant ( P<0.05). No severe complication such as intraspinal leakage, infection, or vascular embolism was found in the two groups. At 1 day after operation, the distribution index of bone cement in group A was mostly grade Ⅴ, which was well dispersed; while in group B, it was mostly grade Ⅱ and grade Ⅴ; the difference of bone cement distribution index between the two groups was significant ( P<0.05). The NRS score, ODI, and Cobb angle of injured vertebra in both groups were significantly improved at 1 day after operation when compared with preoperative ones ( P<0.05). There was no significant difference in the difference of the above indexes between the two groups before and after operation ( P>0.05). CONCLUSION TiRobot-assisted unilateral PKP in the treatment of OVCF of thoracic vertebrae is safe and effective, which can reduce the X-ray transmission times during operation, shorten the operation time, reduce the volume of bone cement injection, and thus decrease incidence of bone cement leakage.

ObjectiveTo establish an early predictive model using serological markers based on LASSO regression for predicting the possibility of HBsAg clearance in HBeAg-negative chronic hepatitis B （CHB） patients treated with pegylated interferon α-2b （PEG-IFNα-2b）， and to investigate the diagnostic value of the model. MethodsA total of 136 HBeAg-negative CHB patients who received PEG-IFNα-2b treatment in the Affiliated Hospital of Xuzhou Medical University from April 2020 to October 2021 were enrolled， among whom 47 received PEG-IFNα-2b for the first time （previously untreated） and 89 received PEG-IFNα-2b after 48 weeks of treatment with nucleos（t）ide analogues （treatment-experienced）. The patients were randomly assigned to a training set with 95 patients and a validation set with 41 patients at a ratio of 7∶3， and related data were collected for both groups， including virological markers， routine blood test results， and liver function at baseline and week 12 of treatment. According to HBsAg status at week 48 of treatment， the patients were divided into seroconversion group with 38 patients and non-seroconversion group with 98 patients. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical variables between two groups. The LASSO regression analysis and univariate and multivariate logistic regression analyses were used to establish a nomogram model； the receiver operating characteristic （ROC） curve was used to assess its predictive ability， and the area under the ROC curve （AUC） was used for comparison of predictive value. ResultsIn the training set， 95 HBeAg-negative CHB patients were treated with PEG-IFNα-2b for 48 weeks， among whom there were 27 patients in the seroconversion group and 68 in the non-seroconversion group. The univariate Logistic regression analysis， with P<0.2 as the criterion for screening， showed that 9 indicators were included in the LASSO regression analysis， i.e.， sex， baseline HBV DNA level， the reduction in HBV DNA in 0 — 12 weeks， baseline HBsAg level， the reduction in HBsAg in 0 — 12 weeks， baseline aspartate aminotransferase （AST） level， the reduction in AST in 0 — 12 weeks， baseline alanine aminotransferase （ALT） level， and the reduction in ALT in 0 — 12 weeks. The LASSO regression analysis showed that sex， baseline HBsAg level， the reduction in HBsAg in 0 — 12 weeks， and the reduction in ALT in 0 — 12 weeks were non-zero variables and were included in the multivariate Logistic regression analysis. The multivariate Logistic regression analysis obtained 4 independent predictive factors， i.e.， sex （odds ratio ［OR］=5.38， 95% confidence interval ［CI］： 1.11 — 34.21， P=0.049）， baseline HBsAg level （OR=0.12， 95%CI： 0.04 — 0.26， P<0.001）， the reduction in HBsAg in 0 — 12 weeks （OR=5.54， 95%CI： 1.97 — 19.18， P=0.003）， and the reduction in ALT in 0 — 12 weeks （OR=0.99， 95%CI： 0.97 — 1.00， P=0.039）. A nomogram model was established based on the results of the multivariate Logistic regression analysis， and the ROC curve was used to assess the predictive value of this nomogram model. This nomogram model had an AUC of 0.934 （95%CI： 0.886 — 0.981） in the training set and an AUC of 0.921 （95%CI： 0.838 — 1.000） in the validation set. In addition， the results of calibration curve and decision curve analyses showed that the model had good consistency and accuracy. ConclusionBased on general information and serological markers， the LASSO regression analysis is used to establish a nomogram model using sex， baseline HBsAg level， the reduction in HBsAg in 0 — 12 weeks， and the reduction in ALT in 0 — 12 weeks， and this model can be used to predict the probability of achieving HBsAg clearance in HBeAg-negative CHB patients treated with PEG-IFNα-2b， which provides important reference and theoretical support for the clinical treatment of patients.

【Objective】 To explore the risk factors of transfusion-related acute lung injury (TRALI). 【Methods】 The clinical symptoms, signs, imaging examinations, and laboratory test results of two patients with TRALI after blood transfusion were retrospectively analyzed, and human leukocyte antigen (HLA) genotyping of the patient and HLA antibodies typing of the plasma donors were performed. 【Results】 The clinical manifestations and laboratory parameters of two patients were consistent with those of TRALI after blood transfusion. After timely clinical respiratory support treatment, all patients were improved. Blood donors produced high titers of HLA-Ⅱ antibodies after pregnancy, including antibodies that specifically recognize the patient′s HLA antigen. 【Conclusion】 Two patients developed TRALI after platelet transfusion from a female blood donor, which was caused by HLA-Ⅱ antibodies.

BackgroundThe mental health level of the prison police is relatively low， so finding innovative ways to improve the mental health of them is of great significance for the safety of prison supervision and the implementation of peaceful China initiative. ObjectiveTo explore the relationship between perceived social support， perceived stress and psychological resilience with mental health of prison police， and to provide references for improving their mental health. MethodsIn March 2022， 424 policemen working in a male prison in a western province were selected by cluster sampling method， and investigated with the Perceived Social Support Scale （PSSS）， Chinese Perceived Stress Scale （CPSS）， Connor-Davidson Resilience Scale （CD-RISC） and General Health Questionnaire 20 （GHQ-20）， then Process 4.2 was used employed to verify the mediating role of perceived stress as well as the moderating role of psychological resilience in the relationship between perceived social support and mental health. Results①Male subjects scored higher on GHQ-20 than female subjects （t=2.095， P<0.05）. ②CPSS score was negatively correlated with PSSS and GHQ-20 scores （r=-0.670， -0.703， P<0.01）， and GHQ-20 score showed a positive correlation with PSSS and CD-RISC scores （r=0.580， 0.693， P<0.01）. ③Perceived social support positively predict mental health （β=0.154， 95% CI： 0.133~0.175， P<0.01）. ④Perceived stress played a mediating role in the relationship between perceived social support and mental health， and the mediation effect size was 0.087， accounting for 88.78% of the total effect （95% CI： 0.064~0.112， P<0.01）. ⑤Psychological resilience played a moderating role in the second half （perceived stress→mental health） of the mediating path of "perceived social support→perceived stress→mental health"（β=0.074， 95% CI： 0.046~0.102， P<0.01）. ⑥Psychological resilience also regulated the mediation effect of perceived stress on the relationship between perceived social support and mental health ［three regression coefficients tested in turn are significant： a=-0.537 （95% CI： -0.594~-0.480， P<0.01）， b1=-0.162 （95% CI： -0.197~-0.127， P<0.01）， b3=0.074 （95% CI： 0.046~0.102， P<0.01）］. ConclusionPerceived social support of prison police has an impact on their mental health both directly and indirectly through perceived stress. In addition， perceived social support of prison police has a moderated mediation effect on mental health， and it is partially moderated by psychological resilience.［ Funded by General Project of Sichuan Prison Administrative Bureau in 2022］
