Objective To analyze three-dimensional imaging characteristics and advantages for severe portal vein stenosis after liver transplantation, and to evaluate clinical efficacy of portal vein stent implantation. Methods Clinical data of 10 patients who received portal vein stent implantation for severe portal vein stenosis after liver transplantation were retrospectively analyzed. Imaging characteristics of severe portal vein stenosis, and advantages of three-dimensional reconstruction imaging and interventional treatment efficacy for severe portal vein stenosis were analyzed. Results Among 10 patients, 3 cases were diagnosed with centripetal stenosis, tortuosity angulation-induced stenosis in 2 cases, compression-induced stenosis in 2 cases, long-segment stenosis and/or vascular occlusion in 3 cases. Three-dimensional reconstruction images possessed advantages in accurate identification of stenosis, identification of stenosis types and measurement of stenosis length. All patients were successfully implanted with portal vein stents. After stent implantation, the diameter of the minimum diameter of portal vein was increased [(6.2±0.9) mm vs. (2.6±1.7) mm, P<0.05], the flow velocity at anastomotic site was decreased [(57±19) cm/s vs. (128±27) cm/s, P<0.05], and the flow velocity at the portal vein adjacent to the liver was increased [(41±6) cm/s vs. (18±6) cm/s, P<0.05]. One patient suffered from intrahepatic hematoma caused by interventional puncture, which was mitigated after conservative observation and treatment. The remaining patients did not experience relevant complications. Conclusions Three-dimensional visualization technique may visually display the location, characteristics and severity of stenosis, which is beneficial for clinicians to make treatment decisions and assist interventional procedures. Timely implantation of portal vein stent may effectively reverse pathological process and improve portal vein blood flow.

Objective To compare the efficacy of percutaneous transforaminal approach and translaminar approach in the treatment of L5/S1 disc herniation(LDH)under endoscopic discectomy.Methods Adopted a retro-spective case-control study,and selected 62 cases of patients with L5/S1 LDH who were treated with percutaneous endoscopic surgery in the spine surgery department of our hospital from June 2020 to December 2022,and the transforaminal approach was used.(TELD)in 32 cases(TELD group),and interlaminar approach(IELD)in 30 cases(IELD group).The observation indicators included intraoperative fluoroscopy times,operation time,hospitaliza-tion days,hospitalization expenses,leg pain VAS score,ODI score,modified MacNab curative effect evaluation and complications.Results All 62 patients successfully completed the operation and follow-up,and no serious complications occurred.There were statistically significant differences in operation time,fluoroscopy times,and hospitalization expenses between the two groups(P<0.001),but there was no significant difference in hospitaliza-tion days between the two groups(P>0.05).The lower extremity VAS scores at the last follow-up and the last follow-up were significantly improved compared with those before operation(P<0.001),and the ODI scores of the two groups were significantly improved at 2 days,1 month and at the last follow-up(P<0.001).At the same time point,there was no statistical difference(P>0.05);there was no significant difference in the excellent and good rate of surgery between the two groups(P>0.05).11 patients with high iliac crest in the TELD group successfully completed the surgery.Conclusions Both the endoscopic surgery through the intervertebral foramen and the inter-laminar approach can achieve satisfactory results in the treatment of L5/S1 LDH.However,local anesthesia through the intervertebral foramen approach reduces hospitalization costs,and patients with high iliac crest can successfully complete the surgery by selecting a suitable puncture path.The translaminar approach has fewer fluoroscopy times and shorter surgical time,but there is a higher risk of dura mater and nerve damage,which requires careful opera-tion for beginners.

Objective To investigate the risk factors for arrhythmia after robotic cardiac surgery. Methods The data of the patients who underwent robotic cardiac surgery under cardiopulmonary bypass (CPB) from July 2016 to June 2022 in Daping Hospital of Army Medical University were retrospectively analyzed. According to whether arrhythmia occurred after operation, the patients were divided into an arrhythmia group and a non-arrhythmia group. Univariate analysis and multivariate logistic analysis were used to screen the risk factors for arrhythmia after robotic cardiac surgery. Results A total of 146 patients were enrolled, including 55 males and 91 females, with an average age of 43.03±13.11 years. There were 23 patients in the arrhythmia group and 123 patients in the non-arrhythmia group. One (0.49%) patient died in the hospital. Univariate analysis suggested that age, body weight, body mass index (BMI), diabetes, New York Heart Association (NYHA) classification, left atrial anteroposterior diameter, left ventricular anteroposterior diameter, right ventricular anteroposterior diameter, total bilirubin, direct bilirubin, uric acid, red blood cell width, operation time, CPB time, aortic cross-clamping time, and operation type were associated with postoperative arrhythmia (P<0.05). Multivariate binary logistic regression analysis suggested that direct bilirubin (OR=1.334, 95%CI 1.003-1.774, P=0.048) and aortic cross-clamping time (OR=1.018, 95%CI 1.005-1.031, P=0.008) were independent risk factors for arrhythmia after robotic cardiac surgery. In the arrhythmia group, postoperative tracheal intubation time (P<0.001), intensive care unit stay (P<0.001) and postoperative hospital stay (P<0.001) were significantly prolonged, and postoperative high-dose blood transfusion events were significantly increased (P=0.002). Conclusion Preoperative direct bilirubin level and aortic cross-clamping time are independent risk factors for arrhythmia after robotic cardiac surgery. Postoperative tracheal intubation time, intensive care unit stay, and postoperative hospital stay are significantly prolonged in patients with postoperative arrhythmia, and postoperative high-dose blood transfusion events are significantly increased.

Objective To investigate the expression,synergistic relationship and clinical significance of alcohol de-hydrogenase(ADH1A)and vascular endothelial growth factor-A(VEGFA)in hepatocellular carcinoma(HCC).Methods The expression and correlation of ADH1A and VEGFA in HCC and adjacent normal tissues were ana-lyzed by GEPIA.TCGA and GSEA were used to analyze the pathway of ADH1A in HCC.The clinical and patho-logical data of 84 patients with HCC were collected,and 54 patients with paracancer normal tissue samples were se-lected as controls to analyze the correlation between ADH1A and VEGFA and clinicopathological parameters of HCC.Immunohistochemistry was used to detect the protein expression of ADH1A and VEGFA in cases and con-trols,and the correlation between the expression of ADH1A and VEGFA and the clinical progression and prognosis of patients with HCC was analyzed based on clinical pathological parameters and Kaplan-Meier.Results Bioinfor-matics analysis found that ADH1A was low-expressed in HCC and VEGFA was highly expressed in HCC,and there was a negative correlation between the two(P<0.001);immunohistochemical detection results showed that the expression of ADH1A in HCC tissue was lower than that in normal tissue adjacent to cancer(P<0.01)while the expression rate of VEGFA in HCC tissue was significantly higher than that of normal tissue adjacent to cancer(P<0.01);The recurrence rate of vascular thrombus and HCC patients in HCC group with high expression of ADH1A was lower(P<0.05).The proportion of tumor diameter>5 cm,high TNM stage,microsatellite and G2-G3 dif-ferentiation in HCC tissues in VEGFA high expression group was higher(P<0.05).Kaplan-Meier survival analy-sis showed that patients with high ADH1A expression and low VEGFA expression had a higher five-year survival rate.Conclusion Low expression of ADH1A and high expression of VEGFA in tumor tissues of patients with HCC indicate tumor progression and can be used as one of the prognostic evaluation indicators for patients with HCC.

Objective:To analyze the incidence trend and epidemiological characteristics of typhoid fever in Fujian Province from 2011 to 2022, and understand the high-incidence population and hotspot areas, and provide evidences to develop more targeted prevention and control measures.Methods:The surveillance data of typhoid fever during 2011-2022 in Fujian Province were obtained from the National Disease Reporting Information System and analyzed with SAS 9.4. The spatial autocorrelation analysis of typhoid fever incidence at county/district levels was performed with ArcGlS 10.8.Results:A total of 5 126 cases of typhoid fever were reported in Fujian Province from 2011 to 2022, with an average annual incidence rate of 1.10/100 000. The average annual incidence rate was 0.96/100 000 from 2011 to 2015, 1.49/100 000 from 2016 to 2019, and 0.81/100 000 from 2020 to 2022. The disease occurred all the year round, with high epidemic season from May to September. A total of 23.59% (1 209/5 126) of the cases occurred at the age of 0-4, and 9.62% (493/5 126) at the age of 5-9. The male to female ratio of the cases was 0.97∶1 (2 524∶2 602) for the whole population, 1.19∶1 (925∶777) for people under 10 years old, 0.75∶1 (1 060∶1 404) for people between 10 and 54 years old, and 1.28∶1 (539∶421) for people over 55 years old. Cases in Ningde City accounted for 30.65% (1 571/5 126) of the total cases. Most hotspots were occurred in Ningde City. Recurrent and clustered cases were found in family members.Conclusions:Typhoid fever was prevalent at a low level in Fujian Province during 2011-2022, indicating that strengthening the prevention and control measures should target key areas and populations. The incidence of typhoid fever in Fujian Province showed spatial aggregation phenomenon, and most cases gathered in Ningde City. Intensive study for the influencing factors of spatial clustering should be conducted.

Objective : To analyze the clinical characteristics of patients with abdominal type allergic purpura(HSP), to improve their diagnostic level, and to explore the risk factors for gastrointestinal bleeding in HSP patients. Methods : A retrospective analysis was conducted on the clinical manifestations, laboratory data, imaging, endoscopic, and pathological characteristics of 98 patients with abdominal type HSP. Based on the occurrence of gastrointestinal bleeding, 98 patients were divided into a bleeding group and a non-bleeding group, and the risk factors for gastrointestinal bleeding in HSP patients were analyzed. Results : Abdominal HSP often presented with abdominal pain, vomiting, vomiting blood, black stools, and bloody stools. Imaging often showed edema and thickening of the duodenum and jejunum, as well as enlargement of surrounding lymph nodes. Under endoscopy, the descending part of the duodenum and jejunum mucosa were commonly congested and edematous with erosion, and ulcers were seen in the distal ileum. Pathology commonly involved acute and chronic inflammation of the mucosa with congestion, edema, and local erosion. Patients with gastrointestinal bleeding had significantly higher levels of white blood cell count(WBC), neutrophil count(NEUT), C-reactive protein(CRP), D-dimer(D-D), and fibrinolytic products(FDP) compared to non-bleeding patients(P<0.05), while levels of red blood cell count(RBC), hemoglobin(HGB), and albumin(ALB) were significantly lower than those of non bleeding patients(P<0.05). Logistic regression analysis showed that decreased ALB and increased FDP were independent risk factors for gastrointestinal bleeding in patients with abdominal HSP(P<0.05). The areas under the ROC curves of ALB and FDP were(AUC=0.877, 95%CI:0.794-0.960,P<0.01) and(AUC=0.806, 95%CI:0.722-0.890,P<0.01), respectively. The maximum value of the Jordan index for ALB was 0.734, with sensitivity and specificity of 89.6% and 83.9%, respectively, and had a critical value of 38.2 g/L. The maximum value of the Jordan index for FDP was 0.577, with sensitivity and specificity of 64.2% and 93.5%, respectively, and had a critical value of 18.14 μg/ml. There was no statistically significant difference in the ROC curves between ALB and FDP. Conclusion For HSP with abdominal pain as the initial symptom, imaging and endoscopic examination are helpful for early diagnosis. Decreased ALB and elevated FDP are independent risk factors for gastrointestinal bleeding in adult patients with abdominal HSP.

Purpose To design PCR combined probes u-sing TaqMan technology to detect the expression of major driver genes in a variety of soft tissue sarcomas at one time,and to dis-cuss whether the combined probes can better assist clinicopatho-logical diagnosis based on histological features and FISH results.Methods Our research group designed 32 pairs of fusion gene probes related to soft tissue sarcoma based on TaqMan tech-nique,involving 10 types of sarcoma.The histopathological specimens of 70 patients with common fusion gene soft tissue sarcoma in our hospital were examined by fusion gene combina-tion,and the histopathological specimens of 30 patients with oth-er soft tissue sarcoma without fusion gene were set as controls.Individual common sarcoma types were analyzed with FISH probe detection.At the same time,the detection performance of the combined probe was evaluated by various methods.Results The soft tissue sarcoma-related fusion gene probe designed by our research group was used to detect the confirmed soft tissue sarcomas,and the results showed that the highest sensitivity was 100％.Among the three types of tumors,protuberant dermatofi-brosarcoma,synovial sarcoma and mucinous liposarcoma were verified by FISH,and the coincidence rate of the two methods was high,with no statistical significance(P＞0.05).The re-sults of interlot and intralot reproducibility of protuberous derma-tofibrosarcoma,mucinous liposarcoma and synovial sarcoma were consistent.Three different concentration limits were used to de-tect the positive plasmid of all the fused gene RNA,and 25 cop-ies/μL was the lowest concentration limit.Conclusion Com-bined with the pathological diagnosis results,TaqMan technology can be used to design PCR combined probes for soft tissue sarco-ma,which have high sensitivity and high specificity and good methodological performance,and meet the needs of primary medical institutions for one-time and rapid auxiliary pathological diagnosis of common soft tissue sarcoma.It provides a rapid and reliable method for the detection of multiple fusion genes in clin-ical soft tissue sarcoma.

Objective:To summarize the clinical features of 14 cases with clinically and genetically diagnosed progressive pseudorheumatoid dysplasia(PPRD) and analyze the characteristics of joint lesions caused by PPRD to provide references for clinical diagnosis and treatment of PPRD.Methods:A retrospective analysis was made on the clinical data and genetic test data of 14 patients admitted to Children′s Hospital, Capital Institute of Pediatrics and cooperative units, from December 2017 to September 2023.An observational retrospective analysis was performed on hospitalization and follow-up data, and correlation factors were analyzed using the Kendall correlation test.Results:The 14 patients, including 6 males and 8 females, were all Chinese Han children.The average age of onset was 6.12 years(2-11 years), the average age of diagnosis was 10.61 years old(5-17 years old), and the average duration of the disease was 4.46 years(0.5-6.0 years) at diagnosis.The number of joint involvements ranged from 4 to 14, with an average of 9.20.There were 12 patients with claudication as the first symptom.All these 14 children had limited hip mobility and no obvious hip pain.The hip joint imaging indicated that space narrowing occurred in 11 cases, femoral neck shortening in 2 cases, femoral head displacement in 4 cases, and articular surface sclerosis, cystic degeneration or bone destruction in 8 cases.The joints of the four limbs were mainly manifested as enlargement of the proximal interphalangeal joints and metacarpophalangeal joints of both hands.The other joints were knees(11 cases), elbows(8 cases), wrists(7 cases) and ankles(5 cases) in the order of easy involvement, and the shoulder joint was less involved(1 case).The spine was mainly characterized by changes in the curvature, and limited movement was found in 8 cases.Thoracic and lumbar spines were mainly involved(13 cases), while cervical involvement was rare(1 case).The duration of the disease at diagnosis was positively correlated with the number of joint involvements and the number of joint mobility limitations( r=0.584, 0.671; P=0.007, 0.002).In this study, 8 children were misdiagnosed as juvenile idiopathic arthritis, and the longest misdiagnosis time was 6 years.All the 14 children had CCN6 gene mutations, including 10 complex heterozygous mutations and 4 homozygous mutations.Five children had c. 342T>G and c. 667T>G, 4 children had c. 589 + 2(IVS4)T>C, 3 children had c. 866dup, and 2 children had c. 136C>T and c. 624dupA. Conclusions:PPRD is characterized by multiple joint involvements, among which hip involvement is the most common.The lesions are serious and easily misdiagnosed as juvenile idiopathic arthritis.The number of affected joints increases gradually with the prolongation of the disease course.
