Objective To investigate the clinical manifestations of familial adenomatous polyposis(FAP).Methods The clinical data of 100 patients with FAP diagnosed in the First Affiliated Hospital of Zhengzhou University from 2011 to 2021 were analyzed retrospectively.Results The main clinical manifestations were bloody stool(44.0%),abdominal pain(40.0%),changes of stool characteristics(25.0%),abdominal distension(18.0%)and diarrhea(17.0%);The most common types of adenomas were villous tubular adenoma(44.9%)and tubular adenoma(32.1%);Extraintestinal manifestations:3 cases of desmoid fibroma,2 cases of osteoma and 1 case of lipoma.47 cases of gastric polyps and the mostly pathological type was fundic gland polyp(34.0%).18 cases of duodenal polyps including 6 cases of adenomatous polyps and most were located at descending duodenum(61.1%).Adenoma canceration occurred in 21 patients.The average age was 38.7 and the canceration mainly occurs in the rectum.The gender,family history,age of onset,number of adenomas,diameter and pathological type of adenomas were statistically compared between patients with and without canceration.It was found that there were significant differences in gender,average age of onset,number of adenoma polyps,diameter of adenoma and pathological type between the two groups(P<0.05).Conclusions FAP is mainly characterized by bloody stool and abdominal pain,with high canceration rate.The risk factors include the age of onset,the number and size of adenomas and the pathological type.The main pathological types are villous tubular adenoma and tubular adenoma.At present,preventive colorectal resection is still the most effective way to treat FAP.No matter what type of methods patients choose,they should be followed up strictly under endoscopy in order to find the lesions in time and treat if necessary.

Objective:To examine the validity and reliability of the Chinese version of the Body Acceptance by Others Scale-2(BAOS-2)in adults.Methods:Totally 616 adults(aged 18-56 years)were selected to test the structural validity,and internal consistency reliability of the scale.The Body Appreciation Scale-2(BAS-2),Func-tionality Appreciation Scale(FAS),Self-Compassion Scale(SCS),Self-Esteem Scale(SES)and Satisfaction with Life Scale(SWLS)were used as criteria to test criterion validity.A sample of 55 adults was retested 2 weeks later for the test-retest reliability.Results:The exploratory factor analysis extracted one factor,and the factor loading range of each item was 0.59-0.76.The confirmatory factor analysis showed that the factor model fit indices were acceptable(x2/df=2.99,CFI=0.91,GFI=0.90,TLI=0.89,RMR=0.04,RMSEA=0.08).The scores of the Chinese version of BAOS-2 were positively correlated with the scores of BAS-2,FAS,SCS,SES and SWLS(r=0.43-0.66,Ps＜0.001).The Cronbach a of the Chinese version of BAOS-2 was 0.90,and the test-retest reliabili-ty(ICC)was 0.65.Conclusion:The Chinese version of the Body Acceptance by Others Scale-2(BAOS-2)has i-deal validity and reliability.

Objective To explore the differences of bone age of radius,ulna,metacarpophalangeal and carpal bones in children with different physiques.Methods Radiographs of children's wrists aged between 4 and 12 years were collected.The bone age of radius,ulna,metacarpophalangeal,and carpal bones were assessed using the Chinese Children's Bone Age Score,and the difference between the two bone ages(the former minus the latter)was recorded.According to gender,age,and physical grouping,the physical group was divided into normal and abnormal groups.The abnormal group was further divided into thin,overweight,and obese groups.A comparative analysis was conducted to determine the differences in bone age between normal and abnormal groups for both males and females at all ages.Results A total of 3 028 children were included,and the differences between the two bone age results for normal boys aged 7-12 years and normal girls aged 5-12 years were not statistically significant(P＞0.05).In boys,there was no significant difference in bone age between the normal group and the thin group(P＞0.05),the difference in bone age between the normal and thin groups at the age of 5-6 years was greater than that between the overweight and obese groups,and the difference was statistically significant(P＜0.05),the difference in bone age between the normal group at 11-12 years and the thin group at 11 years was smaller than that between the overweight and obese groups(P＜0.05).The difference in bone age was smaller in the normal group than in the thin group at 6 years of age for girls(P＜0.05),and larger in the thin group than in the overweight and obese groups at 5 to 6 years old(P＜0.05).Conclusion The difference in bone age between the TW-C RUS series and TW-C C series bone age values is influenced by the child's gender,physique,and age.The difference in bone age between the majority of normal children and the thin group is not statistically significant,but differed from the overweight and obese groups at some ages,most are the overweight and obese boys.

BACKGROUND: Patients with mass-forming pancreatitis (MFP) or pancreatic ductal adenocarcinoma (PDAC) presented similar clinical symptoms, but required different treatment approaches and had different survival outcomes. This meta-analysis aimed to compare the diagnostic performance of contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT) in differentiating MFP from PDAC. METHODS: A literature search was performed in the PubMed, EMBASE (Ovid), Cochrane Library (CENTRAL), China National Knowledge Infrastructure (CNKI), Weipu (VIP), and WanFang databases to identify original studies published from inception to August 20, 2021. Studies reporting the diagnostic performances of CEUS and CECT for differentiating MFP from PDAC were included. The meta-analysis was performed with Stata 15.0 software. The outcomes included the pooled sensitivity, specificity, positive likelihood ratio (+LR), negative likelihood ratio (-LR), diagnostic odds ratio (DOR), and summary receiver operating characteristic (SROC) curves of CEUS and CECT. Meta-regression was conducted to investigate heterogeneity. Bayesian network meta-analysis was conducted to indirectly compare the overall diagnostic performance. RESULTS: Twenty-six studies with 2115 pancreatic masses were included. The pooled sensitivity and specificity of CEUS for MFP were 82% (95% confidence interval [CI], 73%-88%; I2  = 0.00%) and 95% (95% CI, 90%-97%; I2  = 63.44%), respectively; the overall +LR, -LR, and DOR values were 15.12 (95% CI, 7.61-30.01), 0.19 (95% CI, 0.13-0.29), and 78.91 (95% CI, 30.94-201.27), respectively; and the area under the SROC curve (AUC) was 0.90 (95% CI, 0.87-92). However, the overall sensitivity and specificity of CECT were 81% (95% CI, 75-85%; I2  = 66.37%) and 94% (95% CI, 90-96%; I2  = 74.87%); the overall +LR, -LR, and DOR values were 12.91 (95% CI, 7.86-21.20), 0.21 (95% CI, 0.16-0.27), and 62.53 (95% CI, 34.45-113.51), respectively; and, the SROC AUC was 0.92 (95% CI, 0.90-0.94). The overall diagnostic accuracy of CEUS was comparable to that of CECT for the differential diagnosis of MFP and PDAC (relative DOR 1.26, 95% CI [0.42-3.83], P  > 0.05). CONCLUSIONS CEUS and CECT have comparable diagnostic performance for differentiating MFP from PDAC, and should be considered as mutually complementary diagnostic tools for suspected focal pancreatic lesions.

Objective:To evaluate the accuracy of the domestic "Skywalker" surgical robot in implementing personalized lower limb alignment reconstruction scheme in total knee arthroplasty (TKA) and the short-term clinical outcome of robotic assisted TKA.Methods:From September 2020 to January 2021, the data of patients who received surgical robot assisted TKA in 5 clinical centers in China (Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Southwest Hospital affiliated to Third Military Medical University, The Affiliated Hospital of Qingdao University, The First Affiliated Hospital of Chongqing Medical University and Yantai Yuhuangding Hospital, and Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine was the group leader) were prospectively collected and retrospectively analyzed. There were 24 males and 82 females with an average age of 67.6±7.3 years, (range 45-80 years); Average body mass index 26.42±4.31 kg/m 2, all the operation were performed by "Skywalker" surgical robot system according to preoperative design based on CT. The operation time, intraoperative blood loss, hospitalization days and postoperative complications were recorded, and the imaging indexes including hip-knee-ankle (HKA), lateral distal angle of femur (LDFA) and medial proximal angle of tibia (MPTA) measured before and after the operation, implant model indexes (preoperative planning implant model and postoperative implant model) and short-term clinical efficacy indexes [Western Ontario and McMaster Universities (WOMAC) osteoarthritis index] pain score, stiffness score, joint function score, total score and SF-12 score before and 3 months after the operation) were compared. Results:The average follow-up period was 109.60±9.80 d, (range 95-143 d). The average operation time of 106 patients was 105.30±23.22 min; The average intraoperative blood loss was 141.70±58.33 ml; The average length of hospitalization was 5.82±2.80 d. One patient had ischemic stroke after operation, and one patient had abnormal liver function after operation. According to the judgment of the investigator, all of them were not related to the operation. The actual angle error is the difference between the preoperative planning angle and the postoperative measurement angle. The absolute error of 99.1% (105/106) of the HKA angle was within 3°, 90.8% (69/76) of LDFA, 98.7% (75/76) of the MPTA. In 45 patients in one center where data were available, the actual implant models used in all patients were consistent with the preoperative planning size, and there were only differences in version selection such as Asian condyle. WOMAC pain score, joint function score, total score was improved from 7.34±2.85, 25.10±9.85, 34.75±13.02 to 3.34±2.66, 14.68±9.64, 18.66±13.49 before and after operation, respectively, which were statistically significant ( P<0.001) and SF-12 physiological score and psychological score were improved form 27.24±6.42, 30.68±8.26 to 38.83±5.74, 39.36±7.85 before and after operation, respectively, which were statistically significant ( t=7.33, P<0.001; t=4.53, P=0.043). Conclusion:Domestic surgical robot system "Skywalker" can assist the surgeon to achieve accurate and personalized reconstruction of lower limb alignment and achieve satisfactory short-term clinical outcomes. The long-term clinical outcomes of personalized reconstruction and survival rate of implant still need to be further studied.

Objective:To investigate the effects of ultrasound-guided serratus anterior plane block (SAPB) on hemodynamics in children with microtia undergoing auricular reconstruction.Methods:This research was a prospective randomized control study. Patients were prospectively recruited from March 2022 to July 2022 at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Children with microtia undergoing auricular reconstruction with costal cartilage were randomly included in either a SAPB-pre group(SAPB pre-rib harvest group) or a SAPB-post group(SAPB post-rib harvest group). Both groups of children were anesthetized with combined intravenous and inhalation anesthesia. Anesthesia maintenance was provided with i. v. propofol 4-6 mg·kg -1·h -1 and remifentanil 0.1-0.3 μg·kg -1·min -1, sevoflurane at 1% concentration, and a flow rate of 2.5 L/min. During the operation, bispectral index(BIS) was maintained between 40-60, and alterations in mean arterial pressure (MAP) and heart rate (HR) were <20%, compared to the basic values. During the operation, 1% sevoflurane was inhaled to maintain anesthesia. The fluctuation of BIS, MAP, and HR was adjusted by the intraoperative infusion of remifentanil and propofol. Ultrasound-guided SAPB in the SAPB-pre group was performed by an anesthesiologist after tracheal intubation of general anesthesia. In the SAPB-post group, ultrasound-guided SAPB was performed by the same anesthesiologist before the tracheal catheter was removed at the end of the operation, and the concentration of ropivacaine was 0.25% (3 mg/kg). MAP, HR, and BIS were recorded at each time point of admission, pre-rib harvest, during-rib harvest, post-rib harvest, anesthesia extubation, leaving the room. The consumptions of propofol and remifentanil during the operation were also recorded. Continuous data were presented as Mean±SD. Non-repeated measurement parametric variables were compared using the independent samples t-test. Repeated measurement parametric variables were assessed using repeated measures analysis of variance. The same data at varying time points were compared using Dunnett- t test of multiple comparison procedures. Categorical data were compared using the Chi-square test. Results:Sixty children were randomized to SAPB-pre group and SAPB-post group and 30 in each group. The data of gender (boy 22/ girl 8 vs. boy 23/ girl 7), age[(8.03±1.07)years vs. (8.33±1.16)years], body mass index [(17.46±2.79)kg/m 2 vs. (17.23±2.11)kg/m 2], operation time[(185.33±16.29)min vs. (190.00±16.50)min] and length of costocartilage[(23.13±1.46)cm vs. (23.63±1.27)cm] between the two groups showed no significant differences ( P>0.05). There was no significant difference in MAP, HR and BIS values at the time of pre-rib harvest, during-rib harvest, and post-rib harvest in the SAPB-pre group ( P>0.05). In the SAPB-post group, the fluctuations of MAP, HR and BIS values at the time of pre-rib harvest, during-rib harvest and post-rib harvest were obvious ( P<0.01). The consumptions of propofol and remifentanil during the operation in the SAPB-pre group were significantly less than that in the SAPB-post group[(555.67±150.90)mg vs. (788.50±191.02)mg, P<0.01; (745.33±183.56)μg vs. (1 080.00±247.26)μg, P<0.01]. Conclusion:Ultrasound-guided serratus anterior plane block can stabilize the hemodynamics during auricular reconstruction using costal cartilage and reduce the consumption of general anesthetic.

Objective To evaluate the efficacy of bare mental stent (BMS) and covered stent (CS) in the treatment of complete central venous occlusive disease (CVOD) in hemodialysis patients.Methods A total of 66 cases of CVOD who have been treated by endovascular methods successfully in the First Affiliated Hospital of Sun Yat-sen University from Jan 2015 to Jan 2017 were enrolled in this study.According to the type of stent,the patients were divided into two groups,BMS group (n=46)and CS group (n=20).The demographic data,clinical signs and symptoms,and pre-procedure and post-procedure imaging data were followed up and recorded.The primary patency rates were calculated at 1,3,6,9,and 12 months.Results The related symptoms were improved within 2 day post-procedure.The primary patency rates of BMS group in 1,3,6,9 and 12 months were 97.83％,95.65％,69.56％,41.3％,and 34.78％ respectively.The rates of CS group were 100％,100％,95％,65％,and 60％respectively.They did not reached statistical significance for primary patency rates between two groups in 1,3,and 6 months (P ＞ 0.05 respectively).However,from 9 months after procedure,it began to show the significant difference between two groups (P ＜ 0.05).The median patency time of the CS group was (10.30±5.32) months,while BMS group was (8.52±0.49) months.The difference between the two groups was statistically significant (P=0.046).Conclusions Stent implantation for complete occlusion of central venous in hemodialysis patients can get credible effect.The use of CS for CVOD provides superior patency as well as patency time in long period after procedure as compared with BMS.

Objective To evaluate the feasibility and value of multi-detector computed tomography venography (MDCTV) and three dimensional reconstruction image in the assessment of central venous occlusive disease in hemodialysis patients,and in the value of guiding interventional treatments.Methods Sixty hemodialysis patients with swelling of upper limbs were scanned by Toshiba 128-multislice spiral computed tomography (128-MSCT) and totally 80-100 ml non-ionic contrast media was injected into each of the patients via the peripheral veins of the contralateral limb with the rate of 4 ml/s.MSCT scanning was taken by the technique of intelligent triggering after setting scanning triggering threshold,with the monitoring point set in the development of the lumen of inferior vena cava,to detect the position and degree of vascular stenosis.The images were reformed as maximum intensity projection (MIP),volume rendering (VR),curved planar reformation and threedimensional image reconstruction technique.Results MDCTV clearly demonstrated the lesion location in all cases enrolled.Seventy-five occlusive lesions were detected in the total of 60 hemodialysis patients with swelling of upper limbs by MDCTV,of which the lesions of brachiocephalic vein was 47,superior vena cava 15 and subclavian vein 13.Among the 75 stenosis lesions,the number of complete occlusive,severe,moderate and mild stenosis was 31,24,19 and only 1,respectively.MDCTV provided information coincident with that of digital subtraction angiography (DSA),which the correlation index was 0.401,while DSA showed that number of complete occlusive,severe,moderate and mild stenosis was 49,7,14 and 5,respectively.Pereutaneous transluminal angioplasty was performed in 53 patients,and stent placement was done in 40 patients.After interventional treatments,swelling of upper limbs were obviously relieved and vascular accesses got functional recovery to the extent that they could meet the requirement of hemodialysis.Conclusions MDCTV is the first choice to evaluate the condition of central venous occlusive diseases of hemodialysis patients with advantages of non-invasion,high definition and three-dimensional reconstruction.It can provide accurate evaluations of the conditions of occlusive lesions,which can be of great clinical significance to subsequent interventional therapy.
