OBJECTIVE: To investigate the clinical characteristics and genetic etiology of a child with Cortical dysplasia, complex, with other brain malformations 4 (CDCBM4) and epilepsy due to a TUBG1 gene variant. METHODS: A child diagnosed with CDCBM4 and epilepsy at the Children's Medical Center of the Affiliated Hospital of Guangdong Medical University in May 2024 was selected as the study subject. Clinical data were retrospectively analyzed. Peripheral venous blood samples were collected from the child and her parents for genomic DNA extraction. Trio-based whole-exome sequencing (WES) was performed, and candidate variants were validated by Sanger sequencing. According to the Standards and Guidelines for the Interpretation of Sequence Variants established by the American College of Medical Genetics and Genomics (ACMG), candidate variants were classified for pathogenicity. This study was approved by the Medical Ethics Committee of the Affiliated Hospital of Guangdong Medical University (Ethics No.: PJ2021-097). RESULTS: The child, a 4-month-old female infant, had no special facial features, normal limb muscle strength, and increased muscle tone of infantile onset, with generalized tonic-clonic seizures as the main manifestation. During seizures, she exhibited head retroflexion, tightly closed eyes, and tonic convulsions of the limbs, occurring approximately 2-3 times per day. Electroencephalogram suggested bilateral anterior predominant medium-to-high amplitude 7-8 Hz mixed rhythm discharges. Head MRI revealed ventricular system dilatation and pachygyria. Trio-WES results indicated that the child has harbored a TUBG1 gene variant of c.776C>T (p.Ser259Leu). Sanger sequencing verification showed that neither of her parents had carried the same variant, confirming it as de novo in origin. According to the ACMG guidelines, the variant was rated as pathogenic (PS2+PS3+PM2_Supporting+PP3). Combining the child's clinical phenotype, the child was diagnosed as CDCBM4 with epilepsy. CONCLUSION Children with CDCBM4 and epilepsy due to TUBG1 gene variants may show pachygyria or agyria and commonly present with intellectual and motor developmental delays and seizure disorders of variable severity. The heterozygous TUBG1 c.776C>T (p.Ser259Leu) variant is likely the genetic etiology underlying this disorder. The results of this study has expanded the mutational spectrum of the TUBG1 gene associated with CDCBM4 and epilepsy.

All the 10 patients were followed up for 7(range, 3?12)months, achieving disease-free survival. The visick quality of life grade Ⅰ, Ⅱ, Ⅲ, Ⅳ were observed in 7, 3, 0, 0 patients. Postoperative gastroscopy was completed in 7 patients, in which mild anastomotic strictures were noted in 2 patients, but no treatment was required. There was no reflux esophagitis.Conclusion:Intrathoracic Kamikawa anastomosis in combined thoracoscopic and laparoscopic radical resection for esophagogastric junction cancer is safe and feasible, with satisfactory short-term efficacy.

Objective:To compare the difference between breast bracket combined with polyurethane foam and single polyurethane foam in the accuracy of immobilization, providing a better immobilization for breast cancer radiotherapy.Methods:Fifty breast cancer patients who received radiotherapy in Sun Yat-sen University Cancer Center from March 2021 to July 2021 were selected. Among them, 25 patients were immobilized with polyurethane foam (foam group), and the other 25 patients were immobilized with polyurethane foam combined with breast bracket (combination group). All patients were scanned by CBCT once a week to obtain setup errors in the SI, LR and AP directions for t-test. The formula M PTV=2.5 Σ+0.7 σ was used to calculate the margin of the planning target volume(M PTV). Results:The setup errors in the foam group were SI (2.0±3.26) mm, LR (0.88±2.76) mm, AP (1.22±3.55) mm, Rtn -0.24°±0.85°, Pitch 0.16°±1.11°, Roll -0.32°±1.05°, and the M PTV were 6.75 mm, 8.46 mm and 8.73 mm, respectively. The setup errors in the combination group were SI (1.0±3.01) mm, LR (0.62±2.74) mm, AP (1.82±3.21) mm, Rtn 0.64°±0.59°, Pitch 0.71°±1.22°, Roll 0.29°±0.73°, and the M PTV were 6.35 mm, 7.47 mm, and 7.61 mm, respectively. After comparing the setup errors in the three-dimensional directions between two groups, the t value of LR, SI, AP and Rtn, Pitch, Roll was -4.304, -2.681, 1.384, and -9.457, -3.683, -5.323, respectively. And the differences in the LR, SI, Rtn, Pitch and Roll directions were statistically significant (all P<0.05). Conclusions:The immobilization effect of polyurethane foam combined with breast bracket is better and the M PTV is also smaller than those of polyurethane foam alone. Therefore, it is recommended to use polyurethane foam combined with breast bracket for immobilization in breast cancer radiotherapy.

Objective:To investigate the application value of transanal endoscopic partial intersphincteric resection for ultra-low rectal cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 9 ultra-low rectal cancer patients undergoing transanal endoscopic partial intersphincteric resection at the First Affiliated Hospital of Xiamen University from December 2017 to August 2020 were collected. There were 8 males and 1 female, aged from 39 to 62 years, with a median age of 58 years. Observation indicators: (1) surgical and postoperative situations; (2) postoperative pathological examination; (3) follow-up. Follow-up was conducted using outpatient examination and telephone interview to detect postoperative tumor local recurrence and distant metastasis, survival of patients, ileostomy closure, anus function at 3 months after ileostomy closure, male urinary and sexual function and female sexual function at 6 months after rectal surgery. The follow-up was up to February 2021. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1)Surgical and postoperative situations: all 9 patients underwent surgery successfully, without conversion to open surgery. Seven of the 9 patients underwent transanal endoscopic partial intersphincteric resection and the rest of 2 patients with tumor close to the dentate line underwent transanal endoscopic modified partial intersphincteric resection. The operation time and volume of intraoperative blood loss of 9 patients were (267±48)minutes and 50 mL(range, 30?60 mL), respectively. Five of the 9 patients underwent transanal specimen extraction, and 4 patients underwent specimen extraction by an abdominal incision. All 9 patients underwent transanal hand-sewn coloanal anastomosis and protective ileostomy, and two pelvic drainage tubes were indwelled. Transanal drainage tube was placed after anastomosis in 3 of 9 patients. Three cases had intraoperative adverse events and there were no intraoperative adverse event reported in the remaining 6 cases. The time to postoperative initial stoma exhausting and time to postoperative first semi-liquid food intake of 9 patients were 3 days(range, 2?4 days) and 5 days(range, 4?7 days), respectively. One case had Clavien-Dindo grade Ⅰ complication and 2 cases had Clavien-Dindo grade Ⅱ complication during postoperative 30 days and the rest of 6 cases had no postoperative complication. No anastomotic stricture, hemorrhage or urinary retention occurred in 9 patients. The duration of postoperative hospital stay and cost of hospitalization of 9 patients were 11 days(range, 9?23 days) and (6.8±1.3)×10 4 yuan, respectively. (2) Postoperative pathological examination: the diameter of tumor, the distance of distal resection margin, the number of lymph node dissected and the number of positive lymph node of 9 patients were (3.2±1.4)cm, 0.6 cm(range, 0.5?1.5 cm), 17±7 and 0(range, 0?7), respectively. The tumor histopathological type was adenocarcinoma with negative tumor nodule and nerve infiltration in all 9 patients. Only 1 case of 9 patients was found vascular tumor thrombus. The surgical specimens of all 9 patients showed negative for distal and circumferential margins and complete mesorectum. Results of postoperative pathological TNM staging showed that of 6 cases with preoperative T1-T2 staging tumors, 3 cases were classified as pT2N0M0 stage, and 3 cases were classified as pT2N1M0 stage, pT2N2M0 stage or pT3N1M0 stage, respectively. Three cases with preoperative T3 staging tumors were classified as ypT0N0M0 stage, ypT2N0M0 stage or ypT3N0M0 stage, respectively. (3) Follow-up: all 9 patients were followed up for 6 to 13 months, with a median follow-up time of 9 months. No local recurrence, distant metastasis or tumor-related death was found during follow-up. Of the 9 patients, only 1 case did not receive stoma closure and undergo anus function assessment, and the rest of 8 cases underwent stoma closure. Results of postoperative anus function assessment showed 5 cases of accessibility, 2 cases of mild impairment and 1 case of severe impairment. Results of urogenital function assessment showed 6 cases of the 8 male patients of mild impairment, 1 case of moderate impairment and 1 case of severe impairment in micturition function, respectively, and 3 cases of accessibility, 2 cases of mild impairment and 3 cases of moderate impairment in sexual function, respectively. The female patient underwent accessibility of sexual function and the six-item version of the female sexual function index was 25. Conclusion:Transanal endoscopic partial intersphincteric resection can be used for the treatment of ultra-low rectal cancer.

Objective:To evaluate the safety and preliminary efficacy of total neoadjuvant therapy (TNT) model of" neoadjuvant chemoradiotherapy plus consolidation neoadjuvant chemotherapy (CNCT) followed by surgery" for locally advanced gastric cancer.Methods:From 2018 to 2020, 28 patients clinically diagnosed with locally advanced gastric adenocarcinoma or Siewert Ⅱ/Ⅲ adenocarcinoma gastroesophageal junction cancer were prospectively enrolled. The neoadjuvant chemoradiotherapy (NCRT) was delivered with a total dose of 45 Gy, 1.8 Gy/f. Concurrent chemotherapy was S-1 at a dose of 40-60 mg twice daily. Then, patients received four to six cycles of CNCT of SOX regimen at three weeks after neoadjuvant chemoradiotherapy. D 2 lymphadenectomy was performed at 4-6 weeks after CNCT. Results:A total of 28 patients completed the whole therapy. Grade 3 or above adverse events occurred in 3 cases (11%) during CCRT, including thrombocytopenia, leukopenia and anorexia; 2 cases (7%) developed leukopenia and 3 cases (11%) of thrombocytopenia during CNCT. Twenty patients (71%) completed the surgery. The proportion of patients with pathological complete remission (pCR) was 50%. Three patients experienced surgical complications including anastomotic leak, anastomotic stenosis and intra-abdominal sepsis. All were recovered after symptomatic treatment.Conclusion:Interim analysis results demonstrate that TNT can yield significant down-staging for patients with locally advanced gastric cancer, which causes tolerable adverse events and postoperative complications.

PURPOSE: Mismatch repair (MMR) deficiency plays a critical role in rectal cancer. This study aimed to explore the associations between genetic variations in seven MMR genes and adverse events (AEs) and survival of patients with rectal cancer treated with postoperative chemoradiotherapy (CRT). MATERIALS AND METHODS: Fifty single nucleotide polymorphisms in seven MMR (MLH1, MLH3, MSH2, MSH3, MSH6, PMS1 and PMS2) genes were genotyped by Sequenom MassARRAY method in 365 patients with locally advanced rectal cancer receiving postoperative CRT. The associations between genotypes and AEs were measured by odds ratios and 95% confidence intervals (CIs) by unconditional logistic regression model. The associations between genetic variations and survival were computed by the hazard ratios and 95% CIs by Cox proportional regression model. RESULTS: The most common grade ≥ 2 AEs in those 365 patients, in decreasing order, were diarrhea (44.1%), leukopenia (29.6%), and dermatitis (18.9%). Except 38 cases missing, 61 patients (18.7%) died during the follow-up period. We found MSH3 rs12513549, rs33013 and rs6151627 significantly associated with the risk of grade ≥ 2 diarrhea. PMS1 rs1233255 had an impact on the occurrence of grade ≥2 dermatitis. Meanwhile, PMS1 rs4920657, rs5743030, and rs5743100 were associated with overall survival (OS) time of rectal cancer. CONCLUSION: These results suggest that MSH3 and PMS1 polymorphisms may play important roles in AEs prediction and prognosis of rectal cancer patients receiving postoperative CRT, which can be potential genetic biomarkers for rectal cancer personalized treatment.

Objective: The clinical features and prognosis of diffuse large B-cell lymphoma (DLBCL) were analyzed to optimize the treatment. Methods: We retrospectively collected the clinical data of patients with advanced-stage DLBCL from January 2006 to December 2012 in National Cancer Center/Cancer Hospital. The demographic characteristics, clinical stage, histological diagnosis, treatment and prognostic characteristics of these patients were analyzed. Results: A total of 370 patients with median age of 55 years old were recruited in the study. The male-to-female ratio was 1.3∶1. Among the 361 patients who underwent therapy, 280 cases received chemotherapy alone, 65 cases received chemoradiotherapy, and 16 cases received chemotherapy combined with autologous hematopoietic stem cell transplantation (AHSCT). The median follow-up period was 89 months, the 5-year overall survival (OS) rate of the entire cohort was 42.9%. The 5-year OS rate of chemotherapy alone, chemoradiotherapy and chemotherapy combined with AHSCT were 36.8%, 58.5%, 87.5%, respectively. The 5-year OS rate were significantly different between chemoradiotherapy and chemotherapy alone (P=0.001), and between chemotherapy combined with AHSCT and chemoradiotherapy (P=0.040). Univariate analysis showed that the age, Eastern Cooperative Oncology Group performance status (ECOG PS) score, Ann Arbor stage, B symptom, bulky disease, number of extranodal sites, Ki-67 index, lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), international prognostic index (IPI), therapeutic manner and chemotherapy combined with rituximab were significantly associated with the prognosis of advanced DLBCL patients (all P<0.05). Multivariate analysis demonstrated that the age >60 years, Ann Arbor stage IV, with B symptom, with bulky disease, ECOG PS≥1, Ki-67 index > 90%, CD5 expression, up-regulation of serum LDH and β2-MG, and chemotherapy without rituximab were related with the poor prognosis of patients with advanced-stage DLBCL (all P<0.05). Conclusions Chemotherapy combined with rituximab can improve the outcome of patients with advanced-stage DLBCL. The age, stage, B symptom, bulky disease, ECOG PS score, Ki-67 index, CD5 expression, LDH, β2-MG and chemotherapy combined with rituximab are associated with the prognosis of these patients.

Objective To investigate the independent association of serum Fetuin-B with metabolic syndrome in obese Chinese adults.Methods Cross-sectional data on socio-demographic,lifestyle,clinical characteristics, and serum Fetuin-B were collected for 1 318 Chinese adults with central obesity.Associations of serum Fetuin-B with metabolic syndrome and insulin resistance were analyzed using multivariable Logistic regression analysis.Results A total of 820(62.2%)individuals were identified as metabolic syndrome.Subjects with metabolic syndrome showed significantly increased levels of serum Fetuin-B than those with non-metabolic syndrome[(4.18 ±1.39 vs 4.02 ± 1.35)μg/ml,P=0.043].Increased serum Fetuin-B were significantly associated with increased fasting plasma glucose and insulin levels, as well as prevalences of non-alcoholic fatty liver disease(NAFLD)and insulin resistance.After adjustment for potential confounders, serum Fetuin-B was significantly associated with increased risks of metabolic syndrome and insulin resistance(OR=1.19,95%CI 1.06-1.34,P=0.004;OR=1.15,95%CI 1.01-1.30,P=0.031 respectively).Conclusion Serum Fetuin-B level was significantly associated with NAFLD;and elevated serum Fetuin-B was significantly associated with increased risk of metabolic syndrome.
