ABSTRACT
Background: Radiofrequency ablation (RFA) is an alternative modality for thyroid nodules (TNs) and many studies have also confirmed its favorable efficacy and safety. The scope of RFA increases in clinical practice and the aim of our study was to evaluate the efficacy of RFA. Methods: We conducted a prospective study to evaluate the efficacy of RFA for thyroid nodules between January 2017 and December 2022 at our institution. We assessed the change in nodal volume, volume reduction ratio (VRR), technique effective (TE) rate, complete ablation (CA) rate, and nodal regrowth rate and time after RFA. Results: We performed RFA for 1703 patients with TNs between January 2017 and December 2022, of which a total of 970 eligible patients were enrolled in the study. The preoperative volume of TNs was 6.23 ± 8.11ml, with 821 benign and 149 malignant nodules. The post-RFA TE and adjusted TE rate were 80% and 88.8%, respectively. CA was achieved in 145 (14.9%) patients with a mean time of 18.32± 12.98 months; nodal regrowth occurred in 15 (1.5%) patients with a mean time of 29.80 ± 12.47 months. TNs volume and VRR changed significantly at years 1 and 2 after RFA and stabilized after 5 years. A serious postoperative adverse event occurred in one patient with cervical sympathetic chain injury resulting in Horner's syndrome. A transient or permanent damage of the recurrent laryngeal nerve could not be evaluated due to the lack of postoperative laryngoscopy, and this is a significant limitation of the study. Conclusion: The expanded RFA indications were also effective for TNs, with no significant change in long-term efficacy.

BACKGROUND: While the Ohkuma questionnaire is a simple, reliable, and easy-to-use tool to assess dysphagia, none of its versions can be used by the Chinese population. OBJECTIVE: The purpose of this study was to evaluate the internal consistency, reliability and clinical validity of a newly made Chinese version of the Ohkuma questionnaire, and to provide some objective basis for its application in screening dysphagia. MATERIALS AND METHODS: From September 21 to June 2022, 96 patients with dysphagia and 89 asymptomatic subjects were recruited from three hospitals in China to form an observation and a control group, respectively. All subjects completed the Ohkuma questionnaire, Eating Assessment Tool-10, and a Video Fluoroscopy Study of Swallowing. RESULTS: The Cronbach's α coefficient measured in the questionnaire was 0.867, indicating acceptable internal reliability. The analysis of variance generated four main factors to be assessed, showing a good aggregation effectiveness of the questionnaire. The AVE square root values of three factors were greater than the maximum absolute value of the correlation coefficients between factors, indicating good differentiation effectiveness. The sensitivity and specificity scores, together with the positive and negative likelihood as well as diagnostic odds ratios indicate a good reactivity of the questionnaire. Lastly, after adjusting for age and sex, the results of the stepwise linear regression analysis showed that there was a significant positive correlation between the Ohkuma questionnaire and the penetration aspiration scale. CONCLUSIONS: The Chinese version of the Ohkuma questionnaire has good reliability and validity, and can be used as a rapid and effective screening tool for dysphagia.
ABSTRACT
BACKGROUND:Semen cuscutae has the effect of tonifying the liver and kidney system and benefiting the essence.The main pathogenesis of osteoarthritis is deficiency of the liver and kidneys.Therefore,it is hypothesized that there is a link between semen cuscutae and osteoarthritis. OBJECTIVE:To explore the potential relationship between osteoarthritis and semen cuscutae and validate the mechanism of semen cuscutae based on the network pharmacology and molecular docking analysis. METHODS:First,the active ingredients and targets of semen cuscutae were screened in TCMSP,and the genes related to osteoarthritis were collected in the disease databases GeneCard's,OMIM and TTD.The intersected genes were taken and then subjected to a series of analyses and screened for hub genes.Through the enrichment analysis of hub genes,the pathway of semen cuscutae acting on osteoarthritis was selected.The role of hub genes was verified by molecular docking.Therefore,the appropriate active ingredients of semen cuscutae were selected for experimental verification. RESULTS AND CONCLUSION:There were 11 active ingredients of semen cuscutae,66 intersection target genes of semen cuscutae and osteoarthritis,and 12 hub genes,including tumor necrosis factor,interleukin 1B,TP53,RAC-alpha serine/threonine protein kinase(AKT1),vascular endothelial growth factor A,matrix metalloproteinase 9,prostaglandin peroxidase 2,cystatinase 3,epidermal growth factor,peroxisome proliferator-activated receptor gamma,interleukin 10,vascular cell adhesion factor 1.After the enrichment analysis of the hub genes,the classical inflammatory pathway,nuclear factor-κB signaling pathway,was selected for subsequent validation of semen cuscutae to alleviate osteoarthritic inflammation.Through the results obtained after molecular docking of each active ingredient and the hub gene of the pathway prostaglandin peroxidase 2,sesamin with the highest affinity was selected for subsequent cell experiments,and the experimental results confirmed that sesamin,the active ingredient of semen cuscutae,could reduce the expression of cyclooxygenase 2 by inhibiting the nuclear factor-κB signaling pathway induced by interleukin-1β.To conclude,sesamin,the active ingredient of semen cuscutae,reduces the expression of cyclooxygenase 2 by inhibiting the nuclear factor-κB signaling pathway induced by interleukin-1β,thereby improving inflammation in osteoarthritis and expanding the therapeutic effect of semen cuscutae in osteoarthritis.
ABSTRACT
Objective To investigate the effect of transcutaneous electrical acupoint stimulation(TEAS)on postoperative sore throat(POST)in patients undergoing double-lumen bronchial intubation based on general anesthesia.Methods A total of 103 patients,45 males and 58 females,aged 18-64 years,BMI 18-28 kg/m2,ASA physical status Ⅰ-Ⅲ,who received selective operation of double-lumen bronchial intubation under general anesthesia were selected.The patients were divided into two groups using the random number table method:TEAS group(n = 51)and control group(n = 52).In the TEAS group,TEAS on Tiantu acupoint and bilateral Hegu acupoints started 30 minutes before anesthesia induction,and the stimulation lasted until the patients were sent to the recovery room.In the control group,electrodes were placed on the same acupoints without electrical stimulation.The Mallampati grade,number of tracheal intu-bation attempts,compression of cricoid cartilage,resistance during intubation,and double-lumen endobron-chial tube(DLT)retention time were recorded.The incidence and severity of POST,VAS pain scores of sore throat,and the incidence of hoarseness 1 hour,6,and 24 hours after extubation were recorded.Results Compared with the control group,the incidence of POST,the incidence of POST level 1,and VAS pain scores of sore throat were significantly decreased 1 hour,6,and 24 hours after extubation(P＜0.05),the incidence of POST level 2 was significantly decreased 6 hours after extubation in the TEAS group(P＜0.05).There were no significant differences in the situations related to tracheal intubation,and the inci-dence of hoarseness 1 hour,6,and 24 hours after extubation between the two groups.Conclusion The transcutaneous electrical acupoint stimulation on Tiantu acupoint and bilateral Hegu acupoints can signifi-cantly reduce the incidence and severity of postoperative sore throat,and VAS pain scores of sore throat in patients undergoing double-lumen bronchial intubation.

ABSTRACT
Objective:To explore the correlation between post-traumatic stress disorder(PTSD),resilience and quality of life of front-line medical staff in public health emergencies.Methods:From Nov to Dec 2020,the medical staff of 4 COVID-19 designated hospitals in Wuhan were investigated with the general demographic questionnaire,10-item Connor-Davidson Resilience Scale,PTSD Checklist for DSM-5 and Simplify Qualify of Life Scale.Spearman correlation analysis and hierarchical regression analysis were used to investigate the correlation between PTSD,resilience and quality of life.Results:A total of 545 questionnaires were collected in this survey and the valid effective rate was 97.8% (533/545).The score of psychological resilience,PTSD and quality of life of medical staff were 26(20,30),17(8,25),and 20(18,23),respectively.And 13.1% (70/533)of medical staff had obvious PTSD symptoms.There were significant differences in the score of quality of life among medical staff with different genders,occupations and PTSD levels.Spearman correlation analysis results showed that the score of PTSD was negatively correlated with quality of life and psychological resilience(r=-0.488 and-0.464,P＜0.01).The score of psychological resilience was positively correlated with the score of quality of life(r =0.578,P＜0.01).Psychological resilience and PTSD were important predictors of quality of life,with an explanatory capacity of 37.0% .Conclusions:PTSD is a risk factor for quality of life,and psychological resilience is a protective factor for quality of life.In public health emergencies,improving psychological resilience,preventing and treating PTSD can improve the quality of life of medical staff.
ABSTRACT
BACKGROUND:With computer-aided design,melt electrowriting technology can precisely construct 3D tissue engineering scaffolds with specific morphology,which has attracted increasing attention in tissue engineering. OBJECTIVE:To elaborate on the progress of melt electrowriting technology in tissue engineering in recent years. METHODS:PubMed and CNKI were used to retrieve articles about applications of melt electrowriting technology in tissue engineering.The search time was from March 2008 to February 2023.The search terms were"melt electrowriting,melt electrospinning,electrospinning,tissue engineering,scaffold,regeneration"in English and"melt electrowriting,electrospinning,tissue engineering"in Chinese.A preliminary screening of articles was performed by reading the titles and abstracts.Finally,69 articles were included for review. RESULTS AND CONCLUSION:(1)Melt electrowriting technology can achieve precise layer-by-layer deposition of fibers compared to traditional electrospinning technology,which better simulates the complex structure of natural tissues.Compared to other 3D printing technologies,smaller-diameter fibers can be prepared by melt electrowriting technology,resulting in highly ordered porous structures.(2)By combining with other scaffold preparation techniques or materials,such as fused deposition modeling,solution electrospinning technology,and hydrogel,melt electrowriting technology shows great potential in preparing complex tissue engineering scaffolds,which provides certain possibilities for achieving complex tissue regeneration.(3)The regeneration of complex tissues often involves blood vessels,nerves,and soft and hard tissues at the same time.The regeneration of blood vessels and nerves is of great significance to realize the physiological reconstruction of tissues.However,soft and hard tissues have certain difficulties to realize the coordinated regeneration of both due to their different biological and mechanical properties.Melt electrowriting technology has certain advantages in the field of bionic scaffolds due to its good biocompatibility,the ability to prepare multi-scale scaffolds and high porosity.
ABSTRACT
Objective:To investigate the efficacy of combined repair therapy using recombinant bovine basic fibroblast growth factor (R-bFGF) gel and silver ion dressing on the donor site of patients with hand trauma undergoing skin grafting.Methods:Eighty patients with hand trauma who underwent skin grafting at Lishui Central Hospital between October 2020 and October 2021 were enrolled in this study. Using a simple random grouping method, the patients were randomly assigned to a control group and an observation group in a 1:1 ratio, with 40 patients in each group. The control group received conventional vaseline gauze treatment, while the observation group was treated with a combination of R-bFGF gel and silver ion dressing. After 2 weeks of treatment, the repair effects of both groups were evaluated. Before and after treatment, the Connor-Davidson Resilience Scale (CD-RISC) scores and Visual Analog Scale (VAS) scores were compared between the control and observation groups. Additionally, wound healing time, granulation tissue growth time, wound epithelium formation time, and dressing change times as well as total active motion of the fingers were evaluated and compared between the two groups.Results:The repair effect in the observation group was significantly superior to that in the control group ( Z = 4.92, P < 0.05). Furthermore, the recovery of hand function in the observation group was notably better than that in the control group ( Z = 4.31, P < 0.05). The CD-RISC score in the observation group was significantly higher than that in the control group [(77.54 ± 11.35) points vs. (70.61 ± 9.72) points, t = 2.93, P < 0.05]. Additionally, the VAS score, wound healing time, granulation tissue growth time, wound epithelium formation time, and dressing change times in the observation group were significantly lower or fewer than those in the control group [(4.95 ± 1.13) points vs. (5.52 ± 1.24) points, (10.43 ± 1.65) days vs. (15.54 ± 1.71) days, (7.42 ± 2.35) days vs. (11.56 ± 2.71) days, (10.25 ± 2.47) days vs. (12.82 ± 2.64) days, and (2.12 ± 0.63) times vs. (3.35 ± 0.86) times, t = -2.15, -13.60, -7.30, -4.50, -7.30, all P < 0.05]. Conclusion:The combined use of R-bFGF gel and silver ion dressing effectively enhances the repair outcomes of skin donor sites, thereby improving the psychological well-being and reducing pain perception in patients with hand trauma. This therapeutic approach markedly promotes the prognosis and functional recovery of these patients, offering valuable clinical reference for the treatment of hand injuries.
ABSTRACT
Objective To explore the effect of robotic training under position limitation on upper limb of patients with shoulder sub-luxation after stroke. Methods From March to December,2023,sixty patients with shoulder subluxation after stroke in the First Affiliated Hospital of Bengbu Medical University were randomized into conventional group(n = 20),robot group(n = 20)and position-limited group(n = 20).All the groups accepted conventional rehabilitation,while the robot group underwent robot training and the position-limited group underwent robot training under position limitation,for four weeks.Before and after treatment,Fugl-Meyer Assessment-Upper Extremities(FMA-UE)and modified Bar-thel Index(MBI)were used for evaluation,surface electromyography(sEMG)was used to measure the average electromyography(AEMG)and root mean square(RMS)of posterior deltoid fasciculus and supraspinatus during contraction,and musculoskeletal ultrasonography was used to determine the distance of acromion-greater tuber-osity(AGT)of the affected side. Results After treatment,FMA-UE score,MBI score,AEMG,RMS and the distance of AGT improved in all the groups(|t|>10.850,P<0.001),and all the indexes were optimal in the position-limited group(F>42.031,P<0.001). Conclusion Robotic training for upper limb under postural limitation can further improve upper limb function and sub-luxation status,activities of daily living,and peri-shoulder muscle in patients with shoulder subluxation after stroke.
ABSTRACT
Objective:To explore the evaluation value of serum levels of positive pentameric protein 3 (PTX3) and creatine kinase isoenzyme MB (CK-MB) on volume load in patients with chronic decompensated heart failure (CDHF).Methods:A total of 300 CDHF patients who visited the Xingtai Central Hospital from July 2019 to July 2022 were selected and divided into a capacity overload group ( n=182) and a non capacity overload group ( n=118) based on their capacity balance level. Two clinical data sets were compared and analyzed. The receiver operating characteristic (ROC) curve was used to analyze the evaluation value of serum PTX3 and CK-MB levels on the volume load of CDHF patients. The clinical disease characteristics of the two groups of patients were analyzed using univariate analysis, and the influencing factors of volume load of CDHF patients were analyzed using logistic regression. A column chart model was constructed and validated. Results:The body mass index (BMI), waist circumference, systolic blood pressure, diastolic blood pressure, fasting blood glucose (FBG), glycosylated hemoglobin (HbA 1c), C-reactive protein (CRP), uric acid (UA), homeostasis model assessment of insulin resistance (HOMA-IR) of patients in the capacity overload group were higher than those in the non-capacity overload group, and the differences were statistically significant (all P<0.05). The PTX3, CK-MB, pulmonary capillary wedge pressure (PCWP), and CVP levels of patients in the capacity overload group were higher than those in the non-capacity overload group, while albumin, hemoglobin, and hematocrit were lower than those in the non-capacity overload group, and the differences were statistically significant (all P<0.05). The ROC curve showed that the area under the curve (AUC) of PTX3 and CK-MB for predicting capacity overload in CDHF patients are 0.795 and 0.718, with sensitivity of 86.2% and 83.7%, specificity of 65.4% and 68.6%, respectively, indicating high predictive accuracy; The AUC of the two joint predictions is 0.817, the sensitivity was 92.5%, and the specificity was 70.6%. The prediction accuracy was higher than PTX3 ( Z=3.812, P<0.05) and CK-MB ( Z=3.365, P<0.05). PTX3, CK-MB, albumin, hemoglobin, hematocrit, PCWP, and central venous pressure (CVP) were all influencing factors of volume load status in CDHF patients (all P<0.05). The column chart risk prediction model established based on these factors had high accuracy and strong applicability in clinical treatment. Conclusions:Serum PTX3 and CK-MB levels are influencing factors for volume overload in CDHF patients. A column chart model constructed in combination with indicators such as albumin, hemoglobin, hematocrit, PCWP, and CVP has high predictive value for the volume overload status of CDHF.

ABSTRACT
Objective:To investigate the impact of matrix metalloproteinase 13 (MMP13) and low-density lipoprotein receptor-related protein 1 (LRP1) on autophagy of articular chondrocytes in patients with Kashin-Beck disease (KBD).Methods:Human articular cartilage samples obtained from 4 KBD patients and 4 control subjects were collected from Shaanxi Institute for Endemic Disease Prevention and Control, and the expression levels of MMP13 and LRP1 in cartilage tissue were determined using immunohistochemistry (IHC). Chondrocytes were extracted and cultured in vitro, the mRNA and protein expression levels of LRP1 and the autophagy related genes [Beclin 1 (BECN1), microtubule associated protein 1 light chain 3 (LC3)], cartilage injury related genes [MMP13, caspase-3 (CASP3)], chondrocyte differentiation related genes [collagen type Ⅱ alpha 1 chain (COL2A1), and SRY-box transcription factor 9 (SOX9)] were detected by real-time fluorescence quantitative PCR (qRT-PCR) and Western blot (WB), respectively. Chondrocytes from 3 KBD patients were extracted, and MMP13 gene silencing experiment was performed by RNA interference (RNAi) technology, the mRNA and protein expression levels of the above genes were detected by qRT-PCR and WB, respectively. In addition, the antagonist receptor associated protein (RAP) of LRP1 was used to block the LRP1 of human normal chondrocytes (C28/I2 cells), and qRT-PCR and WB were used to detect the mRNA and protein expression levels of LRP1, chondrocyte autophagy, differentiation and cartilage injury related genes, respectively. Results:The IHC results showed that the expression levels of MMP13 (1.67 ± 0.21, 0.59 ± 0.15, 0.51 ± 0.12) in the surface, middle, and deep layers of cartilage tissue of KBD patients were significantly higher than those of control subjects (0.25 ± 0.03, 0.26 ± 0.04, 0.06 ± 0.01), and the differences were statistically significant ( t = - 11.38, P < 0.001; t = - 3.82, - 6.26, P = 0.019, 0.003). The expression levels of LRP1 (0.10 ± 0.02, 0.03 ± 0.01, 0.17 ± 0.03) were significantly lower than those of control subjects (1.63 ± 0.40, 0.44 ± 0.12, 0.34 ± 0.08), and the differences were statistically significant ( t = 6.61, 5.61, 3.64, P = 0.003, 0.005, 0.022). The mRNA and protein expression levels of MMP13, CASP3, SOX9 in chondrocytes of KBD patients were significantly higher than those of control subjects, and the differences were statistically significant ( P < 0.05). The mRNA expression levels of LRP1, LC3, COL2A1 were significantly lower than those of control subjects, and the differences were statistically significant ( P < 0.05). After silencing the MMP13 gene in chondrocytes of KBD patients, there were no significant differences in the mRNA and protein expression levels of LRP1, BECN1, LC3, CASP3, COL2A1, and SOX9 ( P > 0.05). After blocking LRP1 with RAP, the protein expression levels of LRP1, BECN1, LC3, MMP13, COL2A1 and SOX9 in chondrocytes were significantly lower than those in control group ( P < 0.05). Conclusions:There is no direct correlation between MMP13 and abnormal autophagy of articular chondrocytes in KBD patients. After blocking LRP1, the expression of the autophagy related genes BECN1 and LC3 in chondrocytes is decreased.
ABSTRACT
Objective:To investigate the volume management of intermittent veno-venous hemofiltration (IVVH) guided by critical care ultrasound in the treatment of acute kidney injury (AKI) in patients with heart failure (HF).Methods:A total of 216 patients with HF and AKI treated with IVVH in the coronary care unit (CCU) of the Third Central Hospital of Tianjin from April 2019 to June 2022 were selected as the study subjects, the patients were randomly divided into conventional guidance group (107 cases) and ultrasound guidance group (109 cases). According to the recovery of renal function, IVVH was performed 12 hours every day or 12 hours every other day. The conventional guidance group selected the conventional method to formulate IVVH prescription, and the ultrasound guidance group used critical care ultrasound to adjust the treatment parameters of IVVH on the basis of the conventional guidance group. Respiratory variation index (RVI) of inferior vena cava (IVC), right left ventricular end-diastolic transverse area ratio, early diastolic peak mitral flow velocity/mitral annulus velocity peak (E/E'), aortic flow velocity time integral (VTI), cardiac output (CO), bilateral lung ultrasound B-line range, bilateral renal interlobar arteries resistance index (RI) were recorded before and 3, 6, 9 hours after each treatment. The net dehydration rate was adjusted in real time according to the comprehensive results. Urine volume, serum creatinine (SCr), estimated glomerular filtration rate (eGFR), blood B-type brain natriuretic peptide (BNP), β 2-microglobulin (β 2-MG) and cystatin C (Cys C) levels of patients in both groups were monitored before and 3, 7 and 10 days after initial treatment, and renal function recovery and clinical prognostic indexes of patients in both groups were recorded. Results:The dehydration rate of the ultrasound guidance group was slow at the beginning of IVVH, and gradually increased after 6 hours, and the overall dehydration rate was significantly slower than that of the conventional guidance group. In the ultrasound guidance group using critical care ultrasound, the RVI gradually increased, the right left ventricular end-diastolic area ratio gradually decreased, the E/E' ratio gradually decreased, and the range of B-line of bilateral lungs gradually decreased, RI of bilateral renal interlobar arteries decreased. At 3, 7 and 10 days after the first IVVH, renal function related indexes in both groups were significantly improved compared with before treatment, and the decline rate of β 2-MG and Cys C in the ultrasound guidance group was faster than that in the conventional guidance group at early (3 days) [β 2-MG (mg/L): 3.69±1.31 vs. 3.99±1.45, Cys C (mg/L): 2.91±0.95 vs. 3.14±0.96, both P < 0.05], urine volume, SCr and eGFR at 7 days were also significantly improved compared with the conventional guidance group [24-hour urine volume (mL): 1 128.23±153.92 vs. 1 015.01±114.18, SCr (μmol/L): 145.86±32.25 vs. 155.64±28.42, eGFR (mL/min): 50.26±11.24 vs. 46.51±10.61, all P < 0.05]. The time of SCr recovery, the time of reaching polyuria, the total time of IVVH treatment, the time of non-invasive mechanical ventilation and the time of living in CCU in the ultrasound guidance group were shorter than those in the conventional guidance group. The incidences of hypotension, long-term RRT, incidence of major cardiovascular adverse event (MACE) and at 28-day mortality were all lower than those in the conventional guidance group. Kaplan-Meier survival curve showed that the 28-day cumulative survival rate in the ultrasound guidance group was significantly lower than that in the conventional guidance group (Log-Rank test: χ 2 = 3.903, P = 0.048). Conclusion:The strategy of IVVH guided by critical care ultrasound in the treatment of HF with AKI has unique advantages.

Descriptive epidemiological methods were used to analyze the types of infectious diseases, population distribution, time distribution characteristics, as well as the etiological characteristics of major infectious diseases.Results:There were 219 260 cases reported, accounting for 5.73‰(219 260/38 295 800) of the total number of hospital cases, with two peaks of 25 469 and 22 928 cases in 2010 and 2019, respectively. The main category of infectious diseases was class C, accounting for 77.51%(169 947/219 260). According to the classification of transmission routes, fecal-oral transmission infectious diseases were the most common, with 144 712 cases (66.00%), followed by air and droplet transmission infectious diseases with 73 946 cases (33.73%), showing an increasing trend by year. The top five diseases in terms of incidence were hand, foot and mouth disease (114 864 cases), influenza (28 703 cases), varicella (22 190 cases), other infectious diarrheal diseases (21 040 cases) and scarlet fever (11 500 cases). Among the 219 260 children, there were 131 546 males and 87 714 females, with a male-to-female ratio of 1.5 to 1. Children aged≤6 years old comprised the majority, with a total of 189 593 cases (86.47%). The peak period of infectious diseases reporting was from May to July. Hand, foot and mouth disease was mainly caused by Coxsackie virus A16(35.02%(1 258/3 592)), while Coxsackie virus A6 had been increasing rapidly since 2017. The main pathogen of influenza was influenza A virus (62.18%(7 400/11 900)), while other infectious diarrhea was mainly caused by rotavirus (87.55%(4 283/4 892)).Conclusions:There is an intermittent outbreak in the incidence of childhood infectious diseases, and air and droplet transmission infectious diseases have shown an upward trend in recent years. Hand, foot and mouth disease, influenza, varicella, other infectious diarrheal diseases and scarlet fever are the main infectious diseases affecting children. Different diseases have the characteristics of age and onset season. The prevention and control of infectious diseases should be updated gradually according to the epidemic trend. Proper protection should be taken during peak seasons and for key populations.
ABSTRACT
Objective:The study aimed to analyze the clinical and endoscopic characteristics of adult celiac disease (CD) to provide a scientific basis for more effective CD diagnosis and treatment.Methods:In this cross-sectional study, the clinical and endoscopic data of 96 adult CD patients treated in the Department of Gastroenterology of the People′s Hospital of Xinjiang Uygur Autonomous Region from March 2016 to December 2021 were retrospectively collected and analyzed.Results:A total of 96 CD patients were diagnosed, including 33 men and 63 women. The average age was 47±14 years (range, 18-81 years). The disease occurred mainly in the age group of 31-60 years. The median course of the disease was 2.0 (0.2-40.0) years. There were 41 (42.7%) classical and 55 (57.3%) non-classical CD patients. All patients with classical CD showed chronic diarrhea, often accompanied by abdominal pain (46.3%, 19/41), abdominal distension (17.1%, 7/41), anemia (65.9%, 27/41), and chronic fatigue (48.8%, 20/41). The main manifestations of non-classical CD were chronic abdominal pain (58.2%, 32/55), abdominal distension (32.7%, 18/55), anemia (40.0%, 22/55), and osteopenia/osteoporosis (38.2%, 21/55). Compared with non-classical CD, anemia developed more frequently in classical CD, and the difference was statistically significant ( P = 0.012). The incidence of complications in CD patients was 36.5% (35/96), and the main complications were thyroid disease (19.8%, 19/96), connective tissue disease (6.2%, 6/96), and kidney disease (6.2%, 6/96). There was no significant difference between classical and non-classical CD ( P>0.05). The frequency of endoscopic manifestations in CD patients was 84.4% (81/96). Duodenal bulb endoscopy showed nodular changes (72.9%, 70/96), grooved changes (10.4%, 10/96), and focal villous atrophy (9.4%, 9/96). The main manifestations of descending endoscopy were the decrease, flattening, or disappearance of duodenal folds (43.8%, 42/96), scallop-like changes (38.5%, 37/96), and nodular changes (34.4%, 33/96). Conclusions:Adult CD patients are mostly female. CD occurred mainly in the age group of 31-60 years. The clinical manifestations were mainly those of non-classical CD. Some patients often had other autoimmune diseases. Patients with characteristic endoscopic manifestations should be warned about the possibility of developing CD. Clinicians should strengthen the understanding of CD and reduce the related rates of missed diagnosis.
ABSTRACT
Objective:To introduce the application of sleeve reconstruction with bovine pericardium in the reoperation of Behcet's disease with advanced aortic annulus invasion, and to report our experience and the early outcomes.Methods:From August 2012 to May 2022, 19 patients with Behcet's disease developed perivalvular leakage after previous surgery underwent aortic root replacement. They were analyzed retrospectively. Fifteen out of 19 cases underwent conventional aortic root replacement, 4 cases with advanced aortic annulus invasion underwent sleeve reconstruction with bovine pericardium. The medical records were reviewed. Demographic and perioperative data were collected, which included the aortic crossclamp time, intraoperative RBC consumption, length of ICU stay, and major postoperative complications.Postoperative follow-up was accomplished through telephone visit.Results:The median age was 39(36, 42) years old. Five were female. The median interval of diagnosis of perivalvular leak from index surgery was 5(3, 14)months. There was no perioperative death. Fifteen patients underwent conventional aortic root replacement. One patient had intraoperative ECMO impant due to low cardiac output as well as another one had IABP support. CABG was performed in 5 patients. One patient underwent permanent pacemaker implantation after surgery. The median follow-up time for the 15 patients was 55.00(29.25, 71.25)months. Two patients were lost during follow-up. One patient died of infection 3 years after surgery. One patient developed perivalvular leak. Two patient developed distal anastomotic pseudoaneurysm which need reintervention. The median follow-up time for the 4 patients with sleeve reconstruction was 5.5(5, 11.25)months. One patient underwent tracheotomy. Perivalvular leakage and pseudoaneurysm were not appreciated. Four patients were in NYHA class Ⅰ-Ⅱ.Conclusion:The sleeve reconstruction with bovine pericardium is safe and effective in reoperation treating patients with Behcet's disease and advanced aortic annulus invasion.

ABSTRACT
ObjectiveTo investigate the role of endoplasmic reticulum stress genes in the prognosis of pancreatic cancer， and to establish a prognostic prediction model based on the prognostic markers for pancreatic cancer. MethodsTranscriptome sequencing data were downloaded from TCGA and GTEx databases， and MsigDB website was used to obtain endoplasmic reticulum stress genes. A univariate Cox regression analysis was performed to obtain the genes associated with the prognosis of pancreatic cancer， and a consensus clustering analysis was used to construct the molecular typing of pancreatic cancer， while the differentially expressed genes between the two subgroups were obtained. A Lasso regression analysis was used to obtain the core genes associated with the prognosis of pancreatic cancer， which were used to construct a prognostic prediction model for pancreatic cancer. Related datasets were obtained from the GEO database to validate the predictive performance of the model. The CIBERSORT analysis was used to investigate the correlation between risk score and immune infiltration. Quantitative real-time PCR was used to measure the expression of genes in pancreatic cancer tissue and cell lines. The independent-samples t test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between groups. Survival was compared using Log-rank test. The predictive value of the model was evaluated by evaluating the area under the ROC curve. ResultsThe endoplasmic reticulum stress genes CEBPB， MARCKS， PMAIP1， and UBXN10 were independent risk factors for the prognosis of pancreatic cancer， and based on the expression characteristics of these genes， the TCGA pancreatic cancer cohort was divided into two subgroups， i.e.， cluster A and cluster B， while the cluster A patients had a significantly shorter overall survival time than the cluster B patients （P<0.01）. The Lasso regression analysis obtained 5 core genes from the differentially expressed genes affecting the prognosis of pancreatic cancer， and the risk scoring system was established as risk score=0.156×CDA+0.135×AHNAK2+0.020×RHOV+0.095×LY6D+0.054×SPRR1B. The ROC curve analysis showed that this model had good overall predictive performance， with the area under the ROC curve of 0.731 at 1 year， 0.712 at 3 years， and 0.686 at 5 years， and the low-risk group based on this model had a significantly longer overall survival time than the high-risk group （χ2=11.733， P=0.001）. The model showed good predictive performance in the external dataset GSE57495. Quantitative real-time PCR results showed that the expression levels of CDA， AHNAK2， RHOV， LY6D， and SPRR1B in 40 pancreatic cancer tissue samples were significantly upregulated compared with those in normal adjacent tissue samples （t=2.529， 2.458， 3.314， 3.583， and 5.082， all P<0.05）. ConclusionThe expression characteristics of CDA， AHNAK2， RHOV， LY6D， and SPRR1B can be used to predict the prognosis of pancreatic cancer， and the high expression levels of these genes are associated with the poor prognosis of pancreatic cancer patients.
