CAPOS syndrome is an autosomal dominant neurological disorder caused by mutations in the ATP1A3 gene. Initial symptoms, often fever-induced, include recurrent acute ataxic encephalopathy in childhood, featuring cerebellar ataxia, optic atrophy, areflflexia, sensorineural hearing loss, and in some cases, pes cavus. This report details a case of CAPOS syndrome resulting from a maternal ATP1A3 gene mutation. Both the child and her mother exhibited symptoms post-febrile induction,including severe sensorineural hearing loss in both ears, ataxia, areflexia, and decreased vision. Additionally, the patient's mother presented with pes cavus. Genetic testing revealed a c. 2452G>A（Glu818Lys） heterozygous mutation in theATP1A3 gene in the patient . This article aims to enhance clinicians' understanding of CAPOS syndrome, emphasizing the case's clinical characteristics, diagnostic process, treatment, and its correlation with genotypeic findings.

Objective:To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy.Methods:This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0–1; and (7) ASA score I–III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores).Result:[1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10–1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4–13) days. The median time to postoperative oral intake was 7 (range, 2–14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3–18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457).Conclusion:Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.

Objective To evaluate the performance of an artificial intelligence ( AI ) assisted diagnosis system for diabetic retinopathy ( DR) based on deep learning theory. Methods Diagnostic performance of a robot assisted diagnosis system called SongYue for DR was trained by using 25297 retinal images tagged by fundus doctors from multiple hospitals in China. Four types of DR detection model consisting of abnormal DR,referable DR,severe non-proliferative and proliferative DR as well as proliferative DR according to fundus leisions identification were established. The ability of the system to distinguish DR was determined by using receiver operator characteristic (ROC) analysis,sensitivity and specificity of the system. Results SongYue system achieved an area under the ROC curve ( AUC) of 0. 920 for successfully distinguishing normal images from those DR with a sensitivity of 96. 0％at a specificity of 87. 9％. The AUC of SongYue for referable DR was 0. 925,sensitivity was 90. 4％,and specificity was 95. 2％. For severe non-proliferative and proliferative DR,AUC was 0. 845,sensitivity was 72. 7％,and specificity was 96. 2％. For proliferative DR, AUC was 0. 855, sensitivity was 73. 5％, and specificity was 97. 3％. Conclusions SongYue robot assisted diagnosis system has high AUC,sensitivity and specificity for identifying DR, showing good clinical applicable benefits.

Objective To explore the effect of umbilical cord mesenchymal stem cells with positive human leukocyte antigen(HLA)-G on inducing the production of regulatory T cells(Treg) in vitro.Methods Umbilical cord mesenchymal stem cells were isolated from umbilical cord of neonates. PEGFP-N1-HLA-G plasmid was transfected into the human umbilical cord mesenchymal stem cells by liposome transfection, as PEGFP-N1-HLA-G group. PEGFP-N1 empty vector plasmid was transfected into the human umbilical cord mesenchymal stem cells, as PEGFP-N1 group. The human umbilical cord mesenchymal stem cells without empty vector under the same conditions were set as blank control group. Markers of the umbilical cord mesenchymal stem cells were detected using flow cytometry. The expression of HLA-G protein in each group of cells was identified by Western Blot. After mixed-culturing with CD4+T cells in peripheral blood of healthy subjects for 24 h and 48 h, the proportion of CD4+CD25+Foxp3+Treg in total T cells of each group was detected by flow cytometry. Results CD45, CD34 and HLA-DR presented negative expression on umbilical cord mesenchymal stem cells, while CD29, CD44 and CD105 presented positive expression. HLA-G protein could be expressed in the PEGFP-N1-HLA-G group, which had statistically significant difference compared with the blank control group and PEGFP-N1 group (both P<0.01). After PEGFP-N1-HLA-G group and CD4+T cells were mixed-cultured for 24 h and 48 h, CD4+CD25+Foxp3+Treg accounted for (15.3±1.9)% and (14.3±2.1)% of the total T cells respectively, both of which presented statistically significant difference compared with the blank control group and PEGFP-N1 group (all P<0.05). Conclusions Umbilical cord mesenchymal stem cells with HLA-G gene modified can effectively induce the production of CD4+CD25+Foxp3+Treg in vitro.

Objective To evaluate the internal irradiation biological effects of 125I-UdR chitosan nanoparticles in hepatoma cells.Methods The accumulation and distribution of 125I-UdR-CS-DLN in hepatoma cells HepG2 and human liver tissue cells HL-7702 were observed with a confocal microscopy.The internal irradiation biological effects were evaluated by MTT assay,flow cytometry and single cell gel electrophoresis.The apoptosis of in situ rabbit liver tumor treated with 125I-UdR-CS-DLN was assayed by TUNEL staining technique.Results After 30 min of nano-particle treatment,its accumulation in the cytoplasm of HepG2 cells was significantly greater than that in HL-7702 cells.When the concentrations of 125I-UdR-CS-DLN was higher than 37 kBq/ml,the cell viability of HepG2 was significantly lower than that of lL-7702 at 24 and 48 h post-treatment(t =-4.46-6.31,P＜0.05),and the HepG2 cells were arrested at G1 phase and significantly impaired at G2/M phase.In addition,the degrees of DNA doublestrand break of both cell lines irradiated by 125I-UdR-CS-DLN were significantly higher than those treated with 125I-UdR,and the DNA repair capacity of HepG2 cells was significantly lower than that of HL-7702 cells(OTM:t =2.94,P ＜0.05;TDNA％:t =10.64,P ＜0.01).TUNEL staining showed that cell apoptosis could be induced in the rabbit liver carcinoma by 125I-UdR-CS-DLN but not by 125I-UdR.Conclusions The amount of 125I-UdR-CS-DLN absorbed by hepatoma cells is significantly higher than that of 125I-UdR,which suggests that 125 I-UdR-CS-DLN induces more stronger internal radiation biological effects of apoptosis and DNA damage on hepatoma cells.

Objective To investigate the clinical effects of the posterior atlantoaxial pedicle screw fixation combined with unilateral axial spinous process and lamina screws and allogeneic bone graft for atlantoaxial instability.Methods From March 2010 to April 2014,data of 10 patients with atlantoaxial instability who had undergone atlanto-axial vertebral pedicle fixation and interbody fusion combined with posterior atlanto-axial spines lamina nails were retrospectively analyzed.There were 6 males and 4 females with an average age of 39 (range,16-62) years old.The inclusion criteria was atlantoaxial instability together with unilateral vertebral artery segment high cross deformity (7 patients) or atlantoaxial joint break bad involving unilateral pedicle (7 patients).3 patients have spinal cord disease symptoms and physical signs,both suffered limited neck mobility and pain.The VAS scores were 1-8,with an average of 3.70±2.11.Preoperative X-ray,CT three-dimensional reconstruction and MRI were collected.X-ray and CT examination were performed 7 d and 1,3,6,12 months after operation to evaluate the internal fixation and bone grafting fusion.Results There's no occurrence of cervical spinal cord and vertebral artery injury.Screws were successfully implanted.1 case's incision occurred infiltration liquid 3 days after operation.For allograft rejection consideration,we changed the plan,and the infiltrating stopped 5 days later.Other incisions were all primary healing.VAS scores were 1.01±0.89 after operation,which was significantly reduced.X-ray showed good recovery of cervical sequence after the operation,and CT revealed 1 patient with atlas pedicle screw in the medial cortex damage.Spinal canal was without infringing,and the other screw positions were normal.6 months after operation,X-ray or CT examination both showed bony fusion.Conclusion Atlantoaxial pedicle screw fixation combined with unilateral axial spinous process and lamina screws and allograft bone graft fusion for the treatment of atlantoaxial instability can observe good clinical effects.

Objective To observe the effect of early non-invasive positive pressure ventilation(NIPPV)on the treatment of serious hypoxemia induced by acute left heart failure. Methods Forty patients with acute left heart failure( Grade Ⅳ heart function)were randomly divided into two groups. Patients in both groups accepted supportive treatment included cardiotonics, diuretics, vasodilators, in additional to these high concentrations of oxygen were given in conventional group, and non-invasive positive pressure ventilation were given in NIPPV group by biphasic positive airway pressure(BiPAP). Systolic blood pressure, heart rate, respiratory rate, blood-gas analysis( pH, PaO2, PaCO2, SaO2 )and clinical signs were observed at 2 hours after treatments. Results Compared to control,RR( [ 19.55 ± 1.88] vs [21.85 ±3.51 ] ) BPM] ,HR ( [96.40 ±2.80] vs[ 103.20 ±6.78 ] BPM), SBP ( [ 116.30 ± 8.95 ] mm Hg vs [ 122.50 ± 6.13 ] mm Hg), pH (7.404 ± 0.027 vs 7.358 ±0.05) ,SaO2 ( [93.57 ± 1.18]% vs [91.97 ± 1.85]% ) ,PaO2 ( [75.58 ±4.61 ]mm Hg vs [68.38 ±7.95]mm Hg), PaCO2 ( [ 38.69 ± 3.06 ] mm Hg vs [ 43.61 ± 2.65 ] mmHg) were significantly different in NIPPV group( t = 2.582,4.146,2.558,3.534,3.256,3.505,5.428, Ps ＜ 0.05 ). We found no significant differences in the comparisons before treatments. Hypoxia improved in NIPPV group,and the total effective rate was 95% in NIPPV group and 70% in control group,which showed significant difference( x2 =4.329 ,P ＜0.05 ) Conclusion BiPAP non-invasive positive pressure ventilation combined with routine treatment in treating heart failure, could promptly correct hypoxia, improve heart function and shortening disease course.

The correlations between various formation conditions and the membrane pore characterizations of the anodic alumina membrane were investigated for seeking the optimal conditions for the formation of anodic alumina membrane. High purity aluminum foils were used as the starting materials. The anodizations were conducted under three types of electrolytes, 3% sulfuric acid, 5% sulfuric acid and 2.7% oxalic acid, respectively, with different voltages at 0 degrees C for 48 hours. The characterizations of the pore size, the effective porosity and the pore porosity were observed and determined by scanning electron microscopy. The hydraulic conductance of the membranes was measured to confirm that the pores were open and to evaluate the permselectivity of the membranes. The experimental results showed that the ordered pore arrays were obtained for oxidation under our experimental conditions. While the forming voltage was increasing, the pore size and pore porosity increased significantly (P < 0.05), and the effective porosity decreased significantly (P < 0.05). The pore size formed with 3% sulfuric acid or 5% sulfuric acid was much smaller than that with 2.7% oxalic acid as an electrolyte. The hydraulic conductance of anodic alumina membrane that formed under our experimental condition was high than those of the membranes currently available in clinical procedures. The results suggested that the optimal conditions for the formation of anodic alumina membrane to be used in hemodialysis should be 3% or 5% sulfuric acid with 12.5 V to 17.5 V at 0 degrees C for 48 hours.
