Objective:To explore the influence of hypercholesterolemia on the risk of chronic kidney disease (CKD) in the middle-aged and elderly population and the gender differences.Methods:The data came from the "Epidemiological Survey of Chronic Kidney Disease among Adults in Urban Communities in Henan Province". The subjects came from 20 communities in Henan Province, aged ≥45 years old. Groups were based on the quartile of total blood cholesterol level and gender. Multivariate logistic regression and Cochran-Armitage trend test were used to analyze the effect of hypercholesterolemia on the risk of CKD and its gender differences.Results:A total of 4 779 subjects were enrolled into the study, with 1 934 males (40.5%) and 2 845 females (59.5%). The age was (61.3±7.7) years old and the blood cholesterol was (5.0±1.0) mmol/L. The prevalence rates of hypercholesterolemia, albuminuria, and reduced estimated glomerular filtration rate (eGFR) were 10.7%(305/2 845), 6.4%(182/2 845) and 2.8%(79/2 845) in females and 12.7%(245/1 934), 6.9%(133/1 934) and 2.3%(45/1 934) in males respectively. Compared with Q1 group, the prevalence of reduced eGFR in females were higher in Q2 and Q4 groups (both P<0.05). Among males, the prevalence of albuminuria and reduced eGFR increased with increasing blood cholesterol quartile (Cochran-Armitage trend test Z=12.231, 8.862, both P<0.001). Multivariate logistic regression analysis showed that hypercholesterolemia was an independent influencing factor for albuminuria and reduced eGFR ( OR=1.49, 95% CI 1.08-2.07, P=0.016 and OR=1.65, 95% CI 1.03-2.65, P=0.037, respectively). In subgroup analysis of different genders, female hypercholesterolemia was an independent influencing factor for albuminuria and reduced eGFR, while male hypercholesterolemia was not an independent influencing factor ( OR=1.54, 95% CI 0.96~2.46, P=0.075; OR=1.89, 95% CI 0.93-3.89, P=0.082, respectively). Further subgroup analysis based on the interquartile range of serum cholesterol levels found that female hypercholesterolemia was an independent influencing factor for reduced eGFR in the Q2 and Q4 groups ( OR=2.35, 95% CI 1.29-7.61, P=0.003; OR=2.51, 95% CI 1.38-8.39, P=0.001). In males, hypercholesterolemia was an independent influencing factor for albuminuria in the Q2, Q3 and Q4 groups ( OR=1.80, 95% CI 1.01-3.41, P=0.047; OR=1.85, 95% CI 1.02-3.35, P=0.044; OR=2.33, 95% CI 1.33-4.33, P=0.002). Conclusions:Hypercholesterolemia is an independent risk factor for CKD in middle-aged and elderly population, and there are gender differences, which provides a new idea for clinical prevention and control of CKD.

Objective:To construct a computed tomography (CT)-based three-dimensional digital model of small bowel, and investigate its application value for predication of small bowel length before bariatric surgery.Methods:The retrospective and descriptive study was conducted. The clinical data of 3 patients with obesity who were admitted to the Daping Hospital of Army Medical University from December 2018 to January 2019 were collected. There were 2 males and 1 female, aged from from 24 to 44 years, with a median age of 25 years. Patients underwent abdominal enhanced CT examination before operation, and the three-dimensional digital models of small bowel for each patient were constructed respectively. Of the 3 patients, 2 underwent sleeve gastrectomy and 1 underwent Roux-en-Y gastric bypass. The 3 patients were numbered as No.1, No.2, and No.3 according to the operation time. Observation indicators: (1) construction of three-dimensional digital model of small bowel and preoperative prediction of small bowel length; (2) intraoperative measurement of small bowel length and the relative error between preoperative prediction of small bowel length and intraoperative measurement of small bowel length. Count data were represented as absolute numbers or percentages.Results:(1) Construction of three-dimensional digital model of small bowel and preoperative prediction of small bowel length: the three-dimensional digital models of small bowel for each patient were constructed respectively before operation. The volume of small bowel, area of each cross-section for the 10 cross-sections of small bowel, average area of cross-section of small bowel, preoperative prediction of small bowel length in the three-dimensional digital model of small bowel of No.1 patient were 1 312 985 mm 3, 174 mm 2, 154 mm 2, 143 mm 2, 172 mm 2, 345 mm 2, 213 mm 2, 357 mm 2, 173 mm 2, 382 mm 2, 154 mm 2, 227 mm 2, 578 cm. The above indicators of No.2 patient were 1 817 224 mm 3, 274 mm 2, 196 mm 2, 487 mm 2, 413 mm 2, 520 mm 2, 254 mm 2, 231 mm 2, 170 mm 2, 212 mm 2, 168 mm 2, 293 mm 2, 620 cm. The above indicators of No.3 patient were 2 183 019 mm 3, 320 mm 2, 408 mm 2, 281 mm 2, 222 mm 2, 194 mm 2, 219 mm 2, 188 mm 2, 419 mm 2, 326 mm 2, 235 mm 2, 281 mm 2, 777 cm. (2) Intraoperative measurement of small bowel length and the relative error between preoperative prediction of small bowel length and intraoperative measurement of small bowel length: the length of small bowel measured intraoperatively for No.1, No.2, and No.3 patients were 570 cm, 600 cm, and 780 cm, respectively. The relative error between preoperative prediction of small bowel length and intraoperative measurement of small bowel length of No.1, No.2, and No.3 patients were 1.40%、3.33%、0.38%, respectively. Conclusion:Three-dimensional digital model of the small bowel can predict the small bowel length before bariatric surgery.

Objective: This study collected and analyzed data from patients with microtia in multiple clinical centers to obtain the incidence characteristics of microtia in Chinese. Methods: Data from 746 patients with microtia were collected from six hospitals, including theThird Hospital of Hebei Medical University, Hunan Provincial People′s Hospital, the Second Hospital of Hebei Medical University, Weihai Municipal Hospital, West China Hospital Sichuan University, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2016 to December 2017. These data included the results of physical examination and the results of auxiliary examination such as electrocardiogram, chest CT, and abdominal ultrasound. Then, the accompanying malformations of the microtia were statistically analyzed and discussed. Data were entered and processed using SPSS 19.0 statistical software. The relationship between microtia deformities and associated malformations was analyzed by Pearson χ² test. P<0.05 was considered statistically significant. Results: A total of 746 patients with microtia were included, including 513 males and 233 females, aged 5-27 years old. There were 678 cases of unilateral microtia, 68 cases of bilateral microtia; 128 cases of Ⅰ degree, 564 cases of Ⅱ degree, and 54 cases of Ⅲ degree. In addition, 336 cases (45%) were associated with dysplasia of other systems. Detected anomalies were 321 cases of the ear, face, and neck, 261 cases of musculoskeletal system and 76 cases of cardiovascular system, 30 cases of anomalies of the urogenital system, eye, 27 cases of respiratory system, 7 cases of central nervous system, 5 case of digestive system and 1case of diaphragmatic hernia. The proportion of male and female with microtia was 47.0% (241/513) and 40.8% (95/233), respectively, and there was no significant difference in between (χ²=2.493, P=0.114); The composition ratios of unilateral and bilateral associated malformations were 45.7% (310/678) and 38.2% (26/68 ), and there was no significant difference in between (χ²=1.400, P=0.237); The composition ratios of Ⅰ, Ⅱ, Ⅲ degree-associated malformations were 39.8% (51/128), 42.6% (240/564), and 83.3% (45/54), and the difference was statistically significant (χ²= 34.794, P<0.001). Conclusions Microtia has significant clinical heterogeneity with a higher proportion of associated malformations. A higher incidence of associated deformities in patients with severe microtia was observed. Systematic examination is required, which will be helpful to clinical therapy and etiology analysis.

Objective:To investigate the value of sedation in colonoscopy.Methods:A retrospective cohort study of colonoscopy procedures was performed in our institution. Inclusion criteria: (1) colonoscopy procedures were performed by well-trained gastrointestinal surgeons our institution; (2) medical records were complete and colonoscopy was documented properly by notes, videos, photographs, and traceable pathological reports. Those with incomplete records or performed in other institution were excluded. According to above criteria, clinical data of 49 057 cases of clinic and hospitalization receiving diagnostic or therapeutic colonoscopyat Department of Gastric and Colorectal Surgery, Daping Hospital from July 2007 to February 2017 were collected. Among them, there were 24 638 (50.2%) males and 24 419 females, with mean age of (50.6±14.1) (4 to 98) years. Based on the application of sedation during colonoscopy, patients were divided into the sedation group (39 412 cases, 80.3%) and the non-sedation group (9 645 cases, 19.7%). Clinical characteristics of two groups were compared.Results:The sedation rate increased from 45.6% (369/810) to 94.8% (917/967) from 2007 to 2017. As compared to non-sedation group, a higher proportion of females [51.0% (20 095/39 412) vs. 44.8% (4 324/9 645), χ 2=117.422, P<0.001] and younger median age (50.0 years vs. 51.0 years, Z=-4.774, P<0.001) were found in the sedation group, whose differences were statistically significant. In all the 9645 cases in the non-sedation group, about 5.5% (534) of them terminated the examination because of unbearable discomfort, including 244 (4.6%) males and 290 (6.7%) females (χ 2=20.522, P<0.001). Among all the screening population who were ≥50 years old, there was no significant difference in the polyp detection rate (PDR) between the sedation group and the non-sedation group [26.7% (4 737/17 753) vs. 27.4% (1 093/3 984), χ 2=0.937, P=0.330]. The cecal intubation rate (CIR) in the sedation group was significantly higher than that in the non-sedation group [(85.2% (14 422/16 933) vs. 76.1% (2 803/3 682), χ 2=180.032, P<0.001]. Five cases in the sedation group developed iatrogenic colonic perforation (ICP), with none in the non-sedation group. Conclusions:The application of sedation in colonoscopy is increasingly popular. Sedation can significantly improve CIR in colonoscopy, while it has no positive influence on PDR. Meanwhile, sedation increases the medical expense and may result in higher ICP rate.

Robotic-assisted transanal total mesorectal excision (R-TaTME) has unique advantage in low rectal cancer. Single incision plus oneport (SIPOP) laparoscopic operation can synchronously cooperate with robotic-assisted transanal operation, in order to the difficulty of operation, improve the quality of operation and shorten the time of operation. A retrospective analysis was conducted on the clinical and pathological data of one patient who underwent SIPOP synchronously combined with R-TaTME + sigmoid-anal anastomosis + ileostomy at the Department of General Surgery, Army Characteristic Medical Center on September 11, 2019. This 71-year-old patient was male with body mass index of 24.08 kg/m 2 and received preoperative chemotherapy. Rectal adenocarcinoma was confirmed by colonoscopy biopsy, and distance from tumor lower edge to anal verge was 3 cm. MRI indicated T2N1 stage. The operation was completed successfully, and the transabdominal and robotic transanal surgery totaled 117 minutes, with 15 minutes for the robotic transanal preparation step. There was about 20 ml of intraoperative blood loss and no blood transfusion was performed. The patient was discharged 6 days after operation. No intraoperative or postoperative complications occurred. The postoperative TNM staging was stage I (pyT2N0cM0). No recurrence or metastasis was found at postoperative 7 month. It is a safe, effective and feasible technique for patients with low rectal cancer.

Objective: In order to achieve superior aesthetic outcomes of reconstructed ear, analyze and summarize clinical therapeutic effect in completely applying expanded retroauricular flap to encapsulate cartilage scaffold in total auricular reconstruction. Methods: From January 2016 to October 2017, fifty-three congenital microtia patients were treated. A kidney-shaped tissue expander with 50 ml capacity was embedded under retroauricular skin in the first-stage. After excessive expansion to 70 ml and remaining stable for 4 weeks, secondary operation was performed to completely encapsulate cartilage scaffold with expanded retroauricular skin. Postoperative follow-up was carried out on a routine basis. Results: All patients had undergone operations successfully with primary healing of incision. Blood supply of the retroauricular flaps was excellent, and cartilage scaffolds totally survived with no infection and absorption. Satisfactory aesthetic outcome along with clear structure, reasonable symmetry and suitable auriculocephalic angle was acquired in all cases. No color aberration was observed between the front and back side of reconstructed ear. Scars of retroauricular incisions and costal cartilage harvesting incisions were unconspicuous. Conclusions Only using expansive retroauricular flap to fully cover reconstructed cartilage scaffold is reasonable and simple without skin grafting, which is worthy of more application in microtia treatment.
