Objective:To compare the efficacy and safety of transcatheter arterial embolization (TAE) and Viabahn covered stent placement (CSP) for the treatment of delayed hemorrhage after hepatobiliary and pancreatic surgery (DH-HPS).Methods:The clinical data of 41 patients with DH-HPS at the Affiliated Hospital of Xuzhou Medical University from January 2019 to June 2023 were retrospectively analyzed. Among these patients, 27 were male and 14 were female, with an average age of (63.1±10.3) years. 22 patients who underwent TAE was in TAE group and 19 who underwent Viabahn CSP was in CSP group. The interventional treatment effect, blood biochemical indexes and complications were compared between the two groups.Results:In the TAE group, the success rate of hemostasis was 90.9% (20/22), and the rebleeding rate was 9.1% (2/22) after interventional treatment. In the CSP group, the success rate of hemostasis was 94.7% (18/19), and the rebleeding rate of was 5.3% (1/19) after interventional treatment. There was no statistically significant difference in the success rate of hemostasis and the rebleeding rate between the two groups (both P>0.05). The rate of liver function exacerbation after the procedure was 100% (20/20) in the TAE group and 58.8% (10/17) in the CSP group, with a statistically significant difference between the two groups ( χ2=9.77, P=0.002). 37 patients were followed up (18.4±1.7) months, and no rebleeding occurred in all patients. Conclusion:TAE and CSP are both effective for DH-HPS, while CSP is superior to TAE in terms of liver function protection.

Background Few studies have been conducted on the associations of dietary habits with the risks of high normal blood pressure and hypertension in employees of chemical companies in northwest China. Objective To understand the excess intakes of red meat, offal, and salt, the current status of high normal blood pressure and hypertension detection among employees of a large chemical company in Gansu, China, and to analyze the relationships between different dietary habits and the risks of high normal blood pressure and hypertension. Methods A large state-owned chemical enterprise in Gansu Province was selected and 914 employees were recruited by age-stratified random sampling. A set of questionnaires and health examination were adopted for the survey. χ² test was used to compare dietary habits. A logistic regression model was used to analyze the relationships between different dietary habits and the risks of high normal blood pressure and hypertension in the chemical enterprise employees after including the factors significantly different in the χ² test. Results A total of 914 workers completed the survey. Significant differences were found in the distribution of normal blood pressure, high normal blood pressure, and hypertension among the participants grouped by gender, age, body mass index (BMI), and family history of hypertension (P < 0.001). The excess intake rates of red meat, offal, and salt were 25.4%, 29.0%, and 62.1%, respectively. Significant differences were found in the distribution of normal blood pressure, high normal blood pressure, and hypertension among the participants grouped by intakes of meat, offal, and salt (P < 0.001). The highest positive rate of high normal blood pressure was detected in the workers with excess intakes of offal and salt (P < 0.001). The prevalence rate of hypertension increased with higher intakes of red meat, offal, and salt (P < 0.001). After adjusting for gender, age, BMI, family history of hypertension, and other factors, the results of logistic regression showed that the risks of high normal blood pressure and hypertension in workers with excess red meat intake were 1.55 (95%CI: 1.00, 2.38) times and 2.88 (95%CI: 1.63, 5.07) times higher than those in workers with low red meat intake respectively. The risks of high normal blood pressure and hypertension in workers with excess offal intake were 1.75 (95%CI: 1.12, 2.72) times and 1.87 (95%CI: 1.01, 3.44) times higher than those in workers with no offal intake respectively. The risks of high normal blood pressure and hypertension in workers with excess salt intake were 1.80 (95%CI: 1.22, 2.65) times and 2.59 (95%CI: 1.63, 4.11) times higher than those in workers with moderate salt intake, respectively. Conclusion Excessive intakes of red meat, offal or salt are common among the chemical enterprise workers. Excess intakes of red meat, offal, and salt are risk factors for both high normal blood pressure and hypertension. The northwest chemical enterprise should further advocate a healthy and reasonable diet among employees, and propose to reduce the intakes of red meat, offal, and salt.

ObjectiveTo observe the effect of Dahuang Xiezhuo prescription on the clinical symptoms， blood uric acid， and renal tubular function of patients with immunoglobulin A （IgA） nephropathy in stages 1-2 of chronic kidney disease （CKD） complicated with hyperuricemia （HUA）. MethodSixty patients with IgA nephropathy in stages 1-2 of CKD complicated with HUA of spleen and kidney deficiency and combined turbidity and blood stasis syndromes were randomly divided into an observation group and a control group， with 30 cases in each group. The patients in the control group received basic treatment， i.e.， losartan potassium tablets 50-100 mg/time， once per day， and sodium bicarbonate tablets 0.5 g/time， three times per day by oral administration， combined with low-salt， low-fat， and low-purine diet. The patients in the observation group received Dahuang Xiezhuo prescription on the basis of basic treatment， one dose per day， twice a day in the morning and evening with warm water. Both groups were treated for two months. The total scores of traditional Chinese medicine（TCM）syndrome， blood pressure， 24 h urinary protein （24 h UTP）， blood urea nitrogen （BUN）， serum creatinine （SCr） ［glomerular filtration rate （eGFR） was calculated by CKD-epidemiology collaboration （CKD-EPI） formula］， serum uric acid （SUA）， and renal tubular function indexes ［urinary α₁-microglobulin （α₁-MG）， urinary β₂-microglobulin （β₂-MG）， urinary kidney injury molecule-1 （KIM-1）， and neutrophil gelatinase-associated lipocalin （NGAL）］ of the two groups before treatment and two months after treatment were recorded. The clinical efficacy of the two groups was evaluated two months after treatment. ResultAfter 2 months of treatment，the total effective rate in the observation group was 81.48%（22/27），higher than 50.00%（14/28） in the control group（χ² =6.661，P<0.05）. The total scores of TCM syndrome， 24 h UTP， and SUA in the observation group and the observation group were lower than those before treatment （P<0.05）， and compared with the control group after treatment， the observation group decreased more significantly （P<0.05）. After treatment， the blood pressure in the observation group and the observation group was lower than that before treatment （P<0.05）， and there was no significant difference in blood pressure between the two groups after treatment. After treatment， the levels of urinary α₁-MG， β₂-MG， KIM-1， and NGAL in the two groups were lower than those before treatment （P<0.05）， and the observation group was lower than the control group after treatment （P<0.05）. There were no significant inter-group and intra-group differences in BUN， SCr， and eGFR levels before and after treatment. There were no obvious abnormalities in blood routine， liver function， and electrolytes before and after treatment in the two groups， and no adverse reactions such as allergies occurred. ConclusionDahuang Xiezhuo prescription can effectively improve the clinical symptoms of IgA nephropathy with HUA （CKD1-2） patients with spleen and kidney deficiency and combined turbidity and blood stasis syndromes， reduce blood uric acid level， alleviate renal tubular injury， and protect the kidney. The curative effect is better than that of basic treatment.

Objective:To explore the technical points and efficacy of gradual traction-unlocking closed reduction technique (GT-UCRT) for Tile C old pelvic fractures.Methods:From August 2012 to June 2021, 6 patients with Tile C old pelvic fracture were treated and followed up at Department of Orthopedics, The Fourth Medical Center, General Hospital of Chinese PLA. They were 4 males and 2 females with an age of (35.8±10.5) years. By Tile classification: 4 cases of type C1.2, 1 case of type C1.3, and 1 case of type C2; time from injury to surgery: 153.8 (64.3, 204.8) days. The 6 patients were treated with GT-UCRT. The time for gradual traction reduction, operation time, hospital stay, intraoperative blood loss and complications were recorded. The modified Matta score was used to evaluate the reduction quality of pelvic fractures, and the Majeed score was used to evaluate the pelvic function at the last follow-up.Results:The 6 patients were followed up for (40.3±22.9) months (from 12 to 72 months) after surgery. The time for gradual traction reduction was (26.7±4.6) days, operation time (119.2±4.6) minutes, hospital stay (11.5±2.9) days, and intraoperative blood loss (533.3±189.6) mL. By the modified Matta score, the pelvic reduction after surgery was rated as satisfactory in 5 cases and as unsatisfactory in 1 case. The length disparity between both lower limbs in the 6 patients was (6.9±1.6) cm before surgery and (1.0±0.4) cm immediately after surgery, showing a statistically significant difference ( t=11.135, P<0.001). One fracture healed 3 months after surgery and 5 fractures 6 months after surgery. The Majeed pelvic score at the last follow-up was (80.8±9.0) points for the 6 patients, yielding 2 excellent cases, 3 good cases and 1 fair case. Delayed wound healing was reported in 1 patient, calf intermuscular venous thrombosis in 2 cases, and emotional anxiety and sleep disorder in 1 patient. No new lumbosacral plexus injury was found in any patient. Conclusions:In the treatment of Tile C old pelvic fractures, since our self-designed GT-UCRT combines the advantages of Ilizarov technique and unlocking closed reduction technique, it can not only protect the lumbosacral plexus but also obtain satisfactory reduction of the fracture.

【Objective】 To investigate the resource allocation status of blood testing laboratories in 14 blood stations in Gansu Province, explore the impact of differences in basic conditions on the comprehensive testing ability of laboratories, so as to promote the homogenization and standardization of blood screening capacity in blood stations in Gansu and improve blood safety and effectivenes. 【Methods】 An evaluation index system of laboratory resource allocation was constructed and a question-naire was designed. The data of human resources, infrastructure and key equipment of 14 blood stations were collected. The entropy weight -TOPSIS method was used to evaluate and rank the resource allocation of 14 blood stations. 【Results】 In the comprehensive evaluation of blood testing laboratory resource allocation in 14 blood stations in Gansu, the top three were laboratories A, B and I, and the last three were laboratories G, M and J. On the whole, the main issue was unreasonable structure of human resources: most laboratories had unreasonable age structure; except for Laboratory A, there was no personnel with bachelor's degree or above in laboratories; most laboratories had not established a team with intermediate professional titles. In terms of infrastructure, the size of seven laboratories could not meet the needs of modern laboratory testing, and all eight blood stations had no spare nucleic acid laboratories nor a mutual spare laboratory with other blood stations As for the key equipment, 5 laboratories had no automatic blood grouping diagnostic instrument, 5 laboratories only had one set of enzyme immunoassay detection system, 3 laboratories had no spare equipment for the key equipment, which means if the equipment failure could not be repaired in time, the release of results would be affected. 【Conclusion】 There were significant differences in human resources, infrastructure and key equipment of blood testing laboratories in 14 blood stations in Gansu, which had a great impact on laboratory testing capacity and subsequent development. It is suggested that governments at all levels and health administrative departments optimize the input of laboratory resource allocation according to the blood collection volume of blood stations to gradually narrow the differences in resource distribution between different regions, improve the degree of laboratory automation and optimize the personnel structure, so as to build high-quality and efficient blood testing laboratories and ensure the safety of clinical blood use.

Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.

Objective:To investigate the clinical features of JAK2V617F gene mutation and non-mutation in patients with Budd-Chiari syndrome (BCS).Methods:17 and 127 BCS cases with JAK2V617F gene mutation (mutation group) and non-gene mutation (non-mutation group) who were continuously treated with interventional therapy between January 2016 to December 2020 in the Affiliated Hospital of Xuzhou Medical University were selected as the research object for a comparative study. The hospitalization and follow-up data of the two groups were analyzed retrospectively, and the deadline for follow-up was June 2021. Quantitative data group differences were analyzed using the independent sample t-test and Wilcoxon rank sum test. Qualitative data group differences were analyzed with χ2 test or Fisher's exact test. Mann-Whitney U test was used to analyze the differences between groups in rank data. Kaplan-Meier method was used to calculate the patient survival and recurrence rate. Results:Age [(35.41±17.10) years vs. (50.09±14.16) years, t=3.915, P<0.001], time of onset (median duration: 3 months vs. 12 months), and the cumulative survival rate (65.5% vs 95.1%; χ2=5.21, P=0.022) were lower in mutation than non-mutation group. Aaspartate aminotransferase, alanine aminotransferase, prothrombin time, Child-Pugh score, Rotterdam score, Model for End-stage Liver Disease score, hepatic vein thrombosis incidence, and the cumulative recurrence rate after intervention were higher in mutation than non-mutation group. The above all indexes had statistically significant differences ( P<0.05) between the groups. Conclusion:Younger age, acute onset, severe liver injury, high incidence of hepatic vein thrombosis, and poor prognosis are the features of patients with BCS with JAK2V617F gene mutation than non-mutation.

Objective: The relationship between outdoor temperature and blood pressure (BP) has been inconclusive. We analyzed data from a prospective cohort study in northwestern China to investigate the effect of outdoor temperature on BP and effect modification by season. Methods: A total of 32,710 individuals who participated in both the baseline survey and the first follow-up in 2011-2015 were included in the study. A linear mixed-effect model and generalized additive mixed model (GAMM) were applied to estimate the association between outdoor temperature and BP after adjusting for confounding variables. Results: The mean differences in systolic blood pressure (SBP) and diastolic blood pressure (DBP) between summer and winter were 3.5 mmHg and 2.75 mmHg, respectively. After adjusting for individual characteristics, meteorological factors and air pollutants, a significant increase in SBP and DBP was observed for lag 06 day and lag 04 day, a 0.28 mmHg (95% Conclusions This study demonstrated a significant negative association between outdoor temperature and BP in a high-altitude environment of northwest China. Moreover, BP showed a significant seasonal variation. The association between BP and temperature differed by season and individuals' demographic characteristics (age, gender, BMI), unhealthy behaviors (smoking and alcohol consumption), and chronic disease status (CVDs, hypertension, and diabetes).

Objective:To investigate the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) using viabahn stent in patients with Budd-Chiari syndrome (BCS) with extensive hepatic vein occlusion.Methods:Technical success rates, portal pressure gradient (PPG), complications and shunt patency rate of 25 cases with BCS with extensive hepatic vein occlusion treated by TIPS using viabahn stent were retrospectively analyzed. Color Doppler ultrasound was used for postoperative follow-up. Patency rates were evaluated by Kaplan-Meier curve.Results:The technical success rate of TIPS was 100%. Mean PPG decreased from (22.7 ± 6.2) mmHg preoperatively to (9.7 ± 2.6) mmHg postoperatively ( t = 9.58, P < 0.05). Hepatic encephalopathy incidence was 8.0% (2/25), and there were no complications such as intra-abdominal hemorrhage. Twenty-five cases were followed up for 1 to 39 ( mean 19.0 ± 11.9) months, and one patient died of liver failure three months after interventional treatment. The primary patency rates at 1, 2, and 3 years after interventional treatment were 91.3%, 91.3%, and 78.2%, respectively, while the repatency rates were 100%, 92.9%, and 92.9%, respectively. Conclusion:TIPS using viabahn stent can bring better short-term and mid-term curative efficacy in treatment of BCS with extensive hepatic vein occlusion.
