RESUMO
Background/Aims@#Previous studies reveal that immune-mediated neuroinflammation plays a key role in the etiology of esophageal achalasia. However, the understanding of leucocyte phenotype and proportion is limited. This study aim to evaluate the phenotypes of leukocytes and peripheral blood mononuclear cells transcriptomes in esophageal achalasia. @*Methods@#We performed high-dimensional flow cytometry to identified subsets of peripheral leukocytes, and further validated in lower esophageal sphincter histologically. RNA sequencing was applied to investigate the transcriptional changes in peripheral blood mononuclear cells of patients with achalasia. Cell-type Identification by Estimating Relative Subsets of RNA Transcripts (CIBERSORT) was used for estimating the immune cell types. A differential gene expression analysis was performed and the differential expressed genes were subjected to gene ontology, Kyoto Encyclopedia of Genes and Genomes network, protein-protein interaction network construction. @*Results@#An imbalance between innate and adaptive immune cells occurred in achalasia. Specifically, neutrophils and CD8+ T cells increased both in peripheral blood and lower esophageal sphincter in achalasia. Eosinophils decreased in peripheral blood but massively infiltrated in lower esophageal sphincter. CIBERSORT analysis of peripheral blood mononuclear cells RNA sequencing displayed an increased prevalence of CD8+ T cells. 170 dysregulated genes were identified in achalasia, which were enriched in immune cells migration, immune response, etc. Proton pump inhibitor analysis revealed the intersections and gained 7 hub genes in achalasia, which were IL-6, Toll-like receptor 2, IL-1β, tumor necrosis factor, complement C3, and complement C1q A chain. @*Conclusion@#Patients with achalasia exhibited an imbalance of systematic innate and adaptive immunity, which may play an important role in the development of achalasia.
RESUMO
Objective:To evaluate the safety and efficacy of a novel endoscopic anastomosis clip for the stomach perforation via an animal trial.Methods:Six pigs were used as experimental animals, and two perforation models (10-20 mm in diameter) were created by an endoscopic needle-knife in the stomach of each pig. The perforations were then closed by the novel detachable endoscopic anastomosis clip. The animal survival and healing of the lesions were recorded. All the clips were taken out 30 days after operation through endoscopy. Half of the animals were immediately after clip extraction and the other half of the animals survived for another 30 days owing to observation.Results:All clips were implanted successfully and all lesions healed during 30 days after the operation. All animals survived. The clip natural shedding rate was 33.3%(4/12), and the rest of clips were successfully disassembled and removed. All animals were alive 30 days after clip removal with lesions healed.Conclusion:The novel anastomosis clip is safe and effective in animal experiments with easy to operate. It could be recommended for further clinical research with good clinical prospect.
RESUMO
Objective:To investigate the effects of nutritional intake in the first two weeks of life on bronchopulmonary dysplasia (BPD) in preterm infants with gestational age (GA) ≤ 32 weeks.Methods:A retrospective case-control study was conducted 154 preterm infants with birth weight ≤ 1500 g and GA ≤ 32 weeks were enrolled from neonatal intensive care unit (NICU) of Affiliated Hospital of Qingdao University between January 1, 2016 and December 31, 2017. These infants were divided into BPD group or non-BPD group. All clinical and nutritional data were collected and analyzed to investigate the effects of early-life (within 2 weeks after birth) nutritional intake on BPD.Results:Among a total of 154 eligible neonates, 68 were without BPD and 86 with BPD (55.8%). Mild, moderate and severe BPD accounted for 39.5% (34/86), 58.1%(50/86)and 2.4%(2/86)of all BPD cases respectively. GA and birth-weight of BPD group were significantly lower than that of non-BPD group [(28.35 ± 1.55)weeks vs. (30.12 ± 1.23)weeks; (1050.91 ± 190.6)g vs. (1205.88 ± 195.83)g, both P = 0.000]. The duration of mechanical ventilation in BPD group was longer than that in non-BPD group [(2.65 ± 1.08)days vs. (0.47 ± 0.12)days, P < 0.05]. The incidences of complications in BPD group, including neonatal asphyxia, sepsis and patent ductus arteriosus, were all higher than those in non-BPD group( P < 0.05). The fluids and caloric intake, enteral fluids and caloric intake were significantly lower in BPD group on Day 7 and 14 of life ( P < 0.05). The macronutrient intake in BPD group was also consistently lower, reaching statistical significance for carbohydrate intake on Day 7 and 14 of life, and for protein and lipid intake on Day 14 of life ( P < 0.05). Multivariate logistic regression analysis showed that mechanical ventilation ( OR = 2.257, 95% CI: 1.143~4.456, P = 0.019) and GA ( OR = 0.325, 95% CI: 0.215~0.49, P = 0.000) were high-risk factors for BPD. The decreased odds of developing BPD were associated with higher levels of enteral calories on Day 14 of life ( OR = 0.96, 95% CI: 0.94~0.98, P = 0.000), fluids on Day 7 of life ( OR = 0.927, 95% CI: 0.876~0.981, P = 0.009) and protein intake on Day 14 of life ( OR = 0.044, 95% CI: 0.011~0.177, P = 0.000). Conclusions:GA and mechanical ventilation were independent high-risk factors for BPD. Higher intake of protein and enteral calories were protective factors. Proactive early enteral nutrition support, adequate protein intake and decreasing the duration of mechanical ventilation may reduce the risk of BPD.

RESUMO
Objective:To detect whether Toll-like receptor 4 ( TLR4) polymorphisms contributed to primary open angle glaucoma (POAG) in a Chinese population. Methods:A Chinese cohort, including 799 unrelated POAG patients and 799 unrelated controls, was enrolled in our case-control association study. The data was collected at Sichuan Provincial People's Hospital from May 2014 to March 2018. TLR4 functional single nucleotide polymorphisms (SNPs), including rs4986790 and rs4986791, were genotyped by SNaPshot method. Genotype and allele frequencies of the two SNPs were evaluated. This study was approved by the Institutional Review Boards of the Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital (No.2016-58), and complied with the guidelines of the Declaration of Helsinki. Written informed consents were obtained from all subjects prior to the study. Results:Allelic association analysis revealed that there were no significant association detected in the allelic distributions between the POAG cases and controls for SNPs rs4986790 ( P=0.317) and rs4986791 ( OR=1.000, 95% CI =0.062 5-16.002 2, P=1.000) in the TLR4 gene. Conditional analysis of the two SNPs did not show any significant difference in genotype and allele frequency between the case and the control groups. No association of the two SNPs with POAG was detected under four different genetic models, including homozygote, heterozygote, dominant and recessive models. Conclusions:Polymorphisms rs4986790 and rs4986791 in the TLR4 gene are not related to POAG in the Chinese cohort.
RESUMO
Objective:To evaluate the efficacy and safety of endoscopic trans-gastric gallbladder-preserving polypectomy in treatment of gallbladder polyps.Methods:A retrospective analysis was performed on data of 25 patients with gallbladder polyps who underwent endoscopic trans-gastric gallbladder-preserving polypectomy in the endoscopy center of Zhongshan Hospital from September 2017 to August 2019. Completion of operation, operation time, postoperative hospital stay, complications and follow-up results of patients were obtained and analyzed.Results:There were 13 cases of single polyp and 12 cases of multiple polyps, 13 cases of simple gallbladder polyps, and 12 cases of polyps and gallstones. The maximum diameter of polyps was 0.2-1.5 cm. The procedure failed in 1 patient (4%) because of the severe adhesion of abdominal cavity and disappearance of gallbladder when passing through the gastric wall. Twenty-four patients (96%) were successfully treated with endoscopic trans-gastric gallbladder-preserving polypectomy. The operation time was 67.1±26.8 min (35-140 min). The median hospital stay was 4 d (2-5 d). No severe adverse events including delayed bleeding, delayed perforation, diffuse peritonitis or abdominal abscess occurred. During the median follow-up time of 8 months (0-23 months), no patient was lost, no recurrence of polyps and no severe adverse events related to metal clips occurred.Conclusion:Endoscopic trans-gastric gallbladder-preserving polypectomy shows good short-term efficacy and is technically feasible, however, long-term outcome still requires further research.
RESUMO
Objective To explore the high-risk factors of metabolic bone disease (MBD) in premature infants by retrospective analysis of the clinical data so as to provide evidence for optimal clinical management. Methods Clinical data of premature infants with birth weight<1500 g admitted in our hospital from January 2016 to December 2017 were retrospectively analyzed. Infants with serum alkaline phosphatase ( ALP )>500 IU/L and blood phosphorus <1. 5 mmol/L were selected as MBD group and premature infants with birth weight <1500 g were selected randomly as non-MBD group. General data, pulmonary surfactant, continuous positive airway pressure, mechanical ventilation, start time of enteral nutrition, parenteral nutrition ( PN) time, breast feeding time and breast milk fortifier adding, drug usage, hospitalization time and complications were re-corded and compared between the two groups. Results A total of 440 premature infants with birth weight<1500 g were admitted to the hospital during the study period. 58 [ 13. 2% ( 58/440) ] infants were enrolled in the MBD group, among which infants with birth weight<1000 g accounting for 56. 9% ( 33/58) . High birth weight (OR=0. 62, 95% CI:0. 389-0. 990) was an independent protective factor of MBD in premature in-fants. The higher the birth weight, the lower the risk of MBD in premature infants. The longer duration of breast feeding time ( OR= 2. 191, 95% CI:1. 628-2. 950) , later initial time of enteral feeding ( OR=2. 695, 95%CI:1. 710-4. 248), longer duration of PN (OR=6. 205, 95% CI:3. 359-11. 463) time, longer duration of respiratory supporting time ( OR=1. 046, 95% CI:1. 026-. 067) , longer hospital stay time ( OR=1. 703, 95% CI:1. 109-2. 615) and small for gestational age ( OR=2. 965, 95% CI:1. 163-5. 658) were inde-pendent risk factors of MBD in premature infants. The duration of PN was the most important independent risk factor of MBD in premature infants (OR=6.205, 95% CI: 3.359-11.463). Conclusion Multiple factors can lead to MBD of premature infants. The high birth weight is an independent protective factor of MBD and the duration of PN is the most important independent risk factor of MBD in premature infants.
RESUMO
Peroral endoscopic myotomy (POEM) is a novel clinical technique developed in 2010, and has been widely accepted for treating achalasia and esophageal motility disorders, because of its minimal invasiveness and good efficacy. Zhongshan Hospital has published the practice guideline (the "Zhongshan experience") of peroral endoscopic myotomy of achalasia (v1.2018) based on experience combined with literatures. (1) Preoperative evaluation includes clinical symptom assessment, gastroscopy, high-resolution manometry and upper gastrointestinal radiography. (2) Absolute indication is idiopathic achalasia, and age is no longer a contraindication. (3) The criteria include the medical centers with legal qualifications and the operators with over 5 years of clinical experience in gastroenterological surgery or gastroenterology and more than 30 cases of esophageal endoscopic submucosal dissection (ESD). (4) The length of the myotomy is 8 to 10 cm. The recommended location of the myotomy is the anterior or posterior wall. Whether a full-thickness or circular muscle myotomy is chosen is based on patient′s condition. (5) If pleural effusion, atelectasis or pneumothorax occurs, CT examination is recommended during the postoperative period. If patients presents with symptoms such as vomiting and high fever, endoscopic examination and upper gastrointestinal radiography should be performed. (6) Major adverse events include mucosal injury, perforation, bleeding, pneumothorax and pleural effusion. (7) The Eckardt score system and endoscopic examination are used for evaluating the effectiveness after POEM.
RESUMO
Mitochondrial DNA(mtDNA)depletion syndromes(MDS)is a type of autosomal recessive genetic disease characterized by a severe reduction in mtDNA content caused by mutations in the nuclear gene,which results in impaired energy production in affected tissues and organs. According to phenotype,MDS are usually classified as 4 forms:myopathic,encephalomyopathic,hepa - tocerebarl and neurogastrointestinal. The following 9 types of related genes have been reported:a myopathic form associated with mutations in TK2;an encephalomyopathic form associated with mutations in SUCLA2,SUCLGl,or RRM2B;a hepa-tocerebral form associated with mutations in DGUOK,MPVl7, POLG,or Cl0orf2;and a neurogastrointestinal form associated with mutations in TYMP. Some MDS can lead to early death in newborns and infants,so early identification is very important. Combination of biochemical testing,histopatholo-gy,respiratory chain complex testing and mtDNA quantification is needed for the diagnosis. The final diagnosis requires genetic testing.
RESUMO
Objective To study the value of endoscopic treatment for patients with gastric submucosal tumor ( G-SMT ) . Methods The data of 1663 patients with G-SMT undergoing endoscopic treatment was retrospective reviewed from January 2008 to December 2013. Patients′ demographics, treatment outcomes, and follow-up were evaluated. Results A total of 1671 lesions of G-SMT were included in the study. The mean maximum size of lesions was (1. 50±1. 02) cm. Twenty lesions were treated by endoscopic mucosal resection, 296 lesions by endoscopic submucosal dissection (ESD), 7 lesions by ESD+nylon endoloop, 1011 lesions by endoscopic submucosal excavation, 44 lesions by submucosal tunneling endoscopic resection, and 285 lesions by endoscopic full-thickness resection. Endoscopic treatment failed in 8 cases. Postoperative pathology diagnosis included 554 liomyoma, 485 gastrointestinal stromal tumors, 160 ectopic pancreas, and other such as lipoma, neuroendocrine tumor and fibroma. There were 16 cases of bleeding and 18 cases of perforation after treatment. Except for 4 cases of bleeding and 2 cases of perforation underwent additional surgical procedures, all patients were managed by conservative treatments. During a median follow-up time of 36 months of 1226 cases, the recurrence rate was 1%( 12/1226) ,and no death occurred. Conclusion Endoscopic treatment is safe and effective in treating G-SMT for long-term outcomes.

Endoscopic resection (ER) has been a preferred treatment for early gastric cancer (EGC) based on the guidelines. In recent years the technique is developing rapidly. Surgical operation, a traditional treatment, still has its advantages such as complete tumor removal and low recurrence rate. In this review, a long-term outcome comparison of these two methods in EGC is discussed.
RESUMO
Objective To investigate whether increased signal intensity (ISI) can help assess the prognosis in patients with cervical spondylotic myelopathy (CSM) by means of measuring the ratio of signal intensity. Methods A retrospective study with two or more years follow-up of 57 patients with CSM underwent posterior cervical decompression were carried out from February 2000 to February 2006. 1.5T MRI was performed in all patients before surgery. T2-weighted images (T2WI) of sagittal ISI on the cervical spinal cord were obtained, For those with ISI, the values of signal intensity of the spinal cord on T2-weighted image (T2Wl) and TI-weighted image (TIWI) of sagittal view were measured at the location where there was ISI on T2WI, and the ratio of signal intensity of T2WI / T1WI (T2/T1 ratio) at the same level of the spinal cord and with similar area was calculated on the computer. Patients with ISI were subdivided into 2 groups according to T2/T1 ratio. Results ISI was not observed in 20 patients (group 1). The range of T2/T1 ratio of other 37 patients was from 1.28 to 2.80 and the median was 1.65. Nineteen patients were divided into group 2 (ratio range, 1.28-1.63), and 18 into group 3 (ratio range, 1.67-2.80). Significant differences were noted in age at surgery, duration of disease, recovery rate, pre and preoperative JOA score among three different groups.Spearman's rank correlation showed that T2/T1 ratio was positively correlated with age at surgery and duration of disease, negatively with pre- and postoperative JOA score and recovery rate. Conclusion Patients with ISI and higher T2/T1 ratio tend to have relatively severe preoperative state of illness and poor prognosis after surgical intervention. Spinal cord signal intensity change on T2-weighted MRI might be a predictor of a poor outcome in terms of functional recovery rate in patients underwent operations for multi-level CSM.
RESUMO
Objective To investigate the efficacy and safety of the resection of cervical posterior longitudinal ligament (PLL) in Bryan cervical disc arthroplasty. Methods Thirty-one patients underwent Bryan cervical disc implantation only in one level from August 2006 to January 2009 were investigated in this study. Cervical PLL was preserved in 14 patients, but not in other 17 patients. The clinical (JOA score,VAS score for neck and arm pain) and radiographic parameters (the FSU angle, ROM and diameter of the spinal cord) were compared between the two groups. Results No differences were found in terms of age, affected segment, gender, follow-up period, operation time and blood loss between the two groups. Patients underwent removal of cervical PLL were significantly superior to those underwent reservation of cervical PLL in term of clinical outcomes. There were no differences between the two groups with regard to the increase of FSU angle and ROM. However, the diameter of the spinal cord had a significant increase in patients underwent removal of cervical PLL. No severe complication was found in the two groups. Conclusion Removal of the cervical PLL is beneficial for the clinical outcomes and does not have an impact on the angle and ROM of the affected segment. The procedure is safe and feasible.
RESUMO
BACKGROUND: Degenerative lumbar spinal stenosis could be treated by laminectomy internal fixation placement,unilateral or bilateral decompression,posterior laminectomy and so on.However,whether laminectomy internal fixation placement can be used remains unclear.OBJECTIVE: To evaluate the efficacy of interbody fusion cage implantation of pedicle screw fixation,in combination with posterior lumbar laminectomy,bilateral resection and decompression of the inferior articular process,autologous facet joint bone transplantation in the treatment of degenerative lumbar spinal stenosis.METHODS: A total of 41 patients of degenerative lumbar spinal stenosis,who failed after 3 months of conservative therapy,including 23 males and 18 females,at a mean of 60.3 years,Received posterior lumbar laminectomy,bilateral inferior articular process resection and decompression,autologous facet joint bone and cage interbody fusion implant pedicle fixation.They were followed up for 24 months,preoperative and postoperative Japanese Orthopedic Association(JOA)score evaluations were performed to assess the therapeutic efficacy of the patients,radiological examination was done to investigate the graft fusion and vertebral stability of surgical segments in patients.RESULTS AND CONCLUSION: During the follow-up,JOA score significantly increased compared with the preoperative score(P<0.01)and clinical excellence rate was 90%; 40 cases obtained bony fusion,with a fusion rate of 98%,1 patient exhibited signs of lumbar instability.There was no loosening,fracture and other complications after internal fixation,but 2 cases appeared dural tear,1 case pedicle position deviation,1 case pseudoarticulation formation.The results suggest that the posterior lumbar laminectomy,bilateral inferior articular process resection and decompression,autogenous facet joint bone and cage interbody fusion implanted pedicle screw fixation show good clinical effects for the treatment of degenerative lumbar spinal stenosis.
RESUMO
Objective To evaluate the effectiveness of rehabilitative treatment after extended open-doorlaminoplasty of the cervical spine for cervical spondylotic myelopathy.Methods Sixty patients(mean age 61.7 ±12 years)who had undergone extended open-door laminoplasty of the cervical spine for cervical spondylotic myelopa-thy were studied for an average of 40.7 months.They are divided into a rehabilitation group and a control group with 30 patients in each.The patients in the rehabilitation group received systematic rehabilitation therapy pre-and post-operation.In both groups,the neurological recovery rate,the cross-sectional areas of the cervical posterior muscles,and the incidence of axial symptoms and post-operative complications were recorded and compared. Results The wounds of patients in the rehabilitation treatment group healed with no complicating infections,but the wounds of three patients in the control group became infected.There was no statistically significant difference in neurological recovery between the two groups.In the rehabilitation treatment group,the rate of atrophy and the cross-sectional areas of the cervical posterior muscles were significantly lower than in the control group.At the same time,the rate of neck axial symptoms was 23% in the rehabilitation group but 60%in the control group.a difference which was statistically significant. Conclusions Although rehabilitation treatment pre-and post-operation may not speed up neurological recovery,it may prevent postoperative atrophy of the cervical extensors and lower the incidence of neck axial symptoms.
