Objective To investigate the characteristics of ocular movement disorders in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO), and explore the clinical application of videonystagmograph (VNG) exami?nation in the diagnosis and differential diagnosis of MS. Methods Sixteen MS ,10 NMO and 30 control ( sudden deafness ) patients were enrolled prospectively. Ocular movement disorders including saccades, gaze fixation, smooth pursuits, opto?kinetic nystagmus and spontaneous nystagmus were evaluated by using VNG. Results The positive rate of ocular motility disorders in MS patients detected by VGN was 68.75%. The incidences of abnormalities in saccades, smooth pursuits and optokinetic nystagmus were significantly higher in MS than in control groups (P= 0.000, 0.001 and 0.001, respectively). The positive rate of ocular motility disorders in NMO patients detected by VGN was 80.00%. The incidences of abnormal?ities in saccades, gaze fixation, smooth pursuits and optokinetic nystagmus were significantly higher in NMO than control groups (P=0.000, 0.012, 0.000 and 0.002, respectively). The positive rate of ocular motility disorders was not significant? ly different in MS and MS patients (68.5%vs. 80%,P>0.05). Compared with bedside physical examination, VNG showed a notable higher sensitivity in the detection of ocular motility disorders(68.75% vs. 37.50%). Furthermore, VNG disor?ders might indicate brain lesions undetected by MRI. Conclusion This small sample research indicates that VNG is a valuable tool in the detection of ocular motility disorders as well as brain lesions in MS and NMO patients. However, its role in the differential diagnosis between MS and NMO is not confirmed.

OBJECTIVE: To explore the genetic basis for two patients from a family with BCL11A-related intellectual disability (BCL11A-ID). METHODS: Clinical data of the proband and her family members was analyzed. Chromosomal karyotyping analysis, trio-whole exome sequencing (trio-WES) and copy number variation sequencing (CNV-seq) were carried out. For the suspected genetic variants, Sanger sequencing was used to verify, and pathogenicity assessment was conducted. RESULTS: The proband and her mother both had intellectual and language impairment, and their fetal hemoglobin (HbF) was significantly elevated. A heterozygous c.1327_c.1328delTC (p.Ser443Hisfs*128) variant was found in exon 4 of the BCL11A gene by WES, which has resulted in truncated expression of the encoded protein, and Sanger sequencing has verified that the variant was inherited from the mother. The variant was not found in related databases. The variant was predicted as pathogenic according to the guidelines from the American College of Medical Genetics and Genomics (ACMG) (PVS1+PM2+PP1). No karyotypic abnormality was found in the proband, her parents and brother, and no pathogenic CNVs was found in the proband and her parents. CONCLUSION The c.1327_c.1328delTC (p.Ser443Hisfs*128) variant may underlay the BCL11A-ID in the proband and her mother. This de novo variant has expanded the mutational spectrum of the BCL11A gene.

Peribiliary glands (PBG) is a kind of microscopic structure around the intra-hepatic bile ducts and extrahepatic bile ducts. PBG not only participates in maintaining the normal physiological function of biliary epithelial tissue, but also plays an important role in its damage and repair process. Biliary tree stem/progenitor cells in PBG are important cell sources of biliary epithelial regeneration and repair. PBG and the surrounding peribiliary vascular plexus are key influencing factors for the occurrence of ischemic-type biliary lesions (ITBL) after liver transplantation. Based on relevant literatures and clinical practice, the authors summarize the function of PBG as well as its relationship with ITBL.

Objective:To explore the feasibility of technological modification and innovation of full-left/full-right liver splitting in situ for donors and examine the safety of clinical application for liver transplantation (LT).Methods:From March 2021 to June 2022, clinical and surgical data are retrospectively reviewed for 27 donors undergoing full-left/full-right liver splitting in situ and the corresponding 49 recipients undergoing full-left/full-right LT.According to the split liver technique used in donor liver surgery, they are divided into conventional split group(group A, 13 cases)and innovative split group(group B, 14 cases). The corresponding recipients are divided into two groups of recipient C(25 cases)and recipient D(24 cases). General profiles, intraoperative findings, type of vascular allocation and short-term outcomes in two groups are compared.After full-size split liver transplantation(fSLT), follow-ups continued until the end of September 2022.Results:There are 23 males and 4 females in donors.The causes of mortality for donors are traumatic head injury(12 cases)cerebrovascular accident(13 cases)and anoxia encephalopathy(2 cases). Baseline characteristics of two groups indicate that body weight and body mass index(BMI)are higher in group B and blood sodium level is lower than that in group A( P<0.05). No statistical differences exist for the others.Liver splitting time is significantly shorter in group B than that in group A(175 vs.230 min, P=0.022). No significant inter-group difference exists in type of vascular allocation.Retrohepatic inferior vena cava(IVC)is split in one case in group A and 10 cases in group B( P=0.001). Among 20 cases of right hemiliver requiring a reconstruction of segment Ⅴ/Ⅷ venous outflow, 12 cases in group A and 3 cases in group B are reconstructed with conventional independent bridging method(independent type)while another 5 cases in group B reconstruct with innovated technique by bridging Ⅴ/Ⅷ vein for splitting IVC with iliac vessel and molding all outflows as one for anastomosis(combined typ e). There is significant inter-group difference( P=0.004). No significant differences exist in operative duration, anhepatic phase or blood loss between groups C and B, except for T tube retaining in 7 cases of group A and 14 cases of group D( P=0.032). Twelve cases developed a total of 26 instances of≥Clavien-Dindo grade Ⅲ complications.Of which, 7 cases in group C and 5 cases in group D show no significant difference in postoperative morbidity.However, for serious biliary complications(≥Clavien Dindo grade Ⅲ), there are 6 cases in group C versus none in group D( P=0.016). Two cases died from postoperative complication with a postoperative mortality rate of 4.1%.Postoperative hospital stay is similar in two groups.And accumulates 6/12-month survivals were 95.9% and 87.7% for grafts and 95.9% and 92.4% for recipients respectively. Conclusions:Operative duration of full-left/full-right liver splitting in situ tends to shorten with an accumulation of a certain amount of cases.Technological modification and innovation in IVC splitting and segment Ⅴ/Ⅷ vein reconstruction should be further validated as both feasible and safe by short-term outcomes of the corresponding recipients.

OBJECTIVETo evaluate the efficacy and safety of transumbilical single-site laparoscopic surgery for congenital duodenal obstruction (CDO) in neonates.

METHODSA retrospective analysis of clinical data of 15 patients with CDO undergoing transumbilical single-site laparoscopic treatment during November 2017 and January 2018 (single-site group), and 20 patients with CDO undergoing conventional three-hole laparoscopic treatment during August 2017 and October 2017 (three-hole group) was performed. All patients were from the Children's Hospital, Zhejiang University School of Medicine. The operation time, time of initial feeding, time of adequate feeding, length of hospital stay after operation and postoperative complications were compared between two groups.

RESULTSThe operations were completed in all patients. No patient converted to laparotomy, and no massive hemorrhage was observed during operation. The operation time of single-site group was (90±10) min for patients with duodenal diamond-shaped anastomosis and (81±15) min for patients with Ladd operation, while those of three-hole group were (85±9) min and (72±11) min, respectively. Postoperative initial feeding time of single-site group was (5.0±1.0) d, and that of the three-hole group was (4.8±0.8) d. The adequate feeding time was (9.0±1.2) d in the single-site group, and (9.3±0.8) d in the three-hole group. The length of hospital stay after operation was (11.2±2.5) d in the single-site group, and (11.5±2.8) d in the three-hole group. There was no significant difference in operation time, postoperative initial feeding time, adequate feeding time and length of hospital stay after operation between two groups (all >0.05).

CONCLUSIONSTransumbilical single-site laparoscopic surgery for CDO in neonates is safe and effective, and the postoperative abdominal scar is more hidden.

OBJECTIVE: To summarize the clinical characteristics and treatment of type Ⅲ-b congenital intestinal atresia (CIA). METHODS: The clinical data of 12 type Ⅲ-b CIA treated in the Children's Hospital of Zhejiang University School of Medicine from January 2015 to December 2017 were analyzed retrospectively. RESULTS: Of the 12 patients diagnosed as type Ⅲ-b CIA in operation, treatment was refused during operation by their parents in 2 cases. For one child, only the proximal intestine was partly resected in the first operation, dilatation and dysplasia of the duodenum was diagnosed and total duodenum was resected and sutured in the second operation, as the child had postoperative intestinal obstruction. For one child, due to the long distal normal intestine, distal apple-peel like intestine was partly resected without mesenteric reformation. For the rest 8 children total duodenum resection and mesenteric reformation were performed. During the postoperative follow-up, one case was early rejected for further treatment by parents, one case died from complex congenital heart disease, 5 cases had the complication of short bowel syndrome. All 8 survival children received parenteral nutrition support after operation, 5 of whom received parenteral nutrition support for more than 42 days, and they were followed up for 1-3 years after discharge. The short-time efficacy was satisfactory. CONCLUSIONS For children with type Ⅲ-b CIA, the distal apple-peel like intestine should be preserved as much as possible, the mesenteric reformation should be performed and the proximal dilated bowel should be partly resected and sutured. Postoperative nutritional support and early intestinal rehabilitation contribute to the compensation for rest intestines.

Helicobacter pylori (H. pylori), creating a global infection rate over 50%, presents great challenges in clinical therapies due to its complex pathological microenvironment in vivo. To improve the eradication efficacy, herein we fabricated a pharmaceutical vesicle RHL/Cl-Ch-cal where cholesterol-PEG, calcitriol and first-line antibiotic clarithromycin were co-loaded in the rhamnolipid-composed outer lipid layer. RHL/Cl-Ch-cal could quickly penetrate through gastric mucus layer to reach H. pylori infection sites, and then effectively destroyed the architecture of H. pylori biofilms, killed dispersed H. pylori and inhibited the re-adhesion of residual bacteria (called biofilms eradication tetralogy). Moreover, RHL/Cl-Ch-cal activated the host immune response to H. pylori by replenishing cholesterol to repair lipid raft on the cell membrane of host epithelial cells. Finally, RHL/Cl-Ch-cal killed the intracellular H. pylori through recovering the lysosomal acidification and assisting degradation. In experiments, RHL/Cl-Ch-cal demonstrated prominent anti-H. pylori efficacy in the classical H. pylori-infected mice model. Therefore, the study provides a "comprehensive attack" strategy for anti-H. pylori therapies including biofilms eradication tetralogy, immune activation and intracellular bacteria killing.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.
