ABSTRACT
ABSTRACT Objective: Interstitial cystitis (IC)/bladder pain syndrome (BPS) is a chronic inflammatory disease that can cause bladder pain and accompanying symptoms, such as long-term urinary frequency and urgency. IC/BPS can be ulcerative or non-ulcerative. The aim of this study was to explore the core genes involved in the pathogenesis of ulcerative IC, and thus the potential biomarkers for clinical treatment. Materials and Methods: First, the gene expression dataset GSE11783 was downloaded using the Gene Expression Omnibus (GEO) database and analyzed using the limma package in R to identify differentially expressed genes (DEGs). Then, the Database for Annotation, Visualization and Integrated Discovery (DAVID) was used for Gene Ontology (GO) functional analysis, and the Kyoto Encyclopedia of Genes and Genomes (KEGG) was used for pathway enrichment analysis. Finally, the protein-protein interaction (PPI) network was constructed, and key modules and hub genes were determined using the STRING and Cytoscape software. The resulting key modules were then analyzed for tissue-specific gene expression using BioGPS. Results: A total of 216 up-regulated DEGs and 267 down-regulated genes were identified, and three key modules and nine hub genes were obtained. Conclusion: The core genes (CXCL8, CXCL1, IL6) obtained in this study may be potential biomarkers of interstitial cystitis with guiding significance for clinical treatment.

OBJECTIVES: Anemia and changes in platelets (PLT) are common in inflammatory bowel disease (IBD). In our study, we aimed to verify whether PLT count can independently reflect the severity of IBD. METHODS: In our hospital, 137 Crohn's Disease (CD), 69 Ulcerative colitis (UC) patients, and 412 healthy controls were included to compare the differences in PLT count. In addition, the effect of anemia, C-reactive protein (CRP), age, CD activity index (CDAI) or Mayo on PLTs was also analyzed. If PLTs independently affected CD or UC, we used the receiver operating characteristic (ROC) curve to verify the diagnostic value and obtain the cut-off value of PLT. RESULTS: CD and UC patients had higher PLT than controls (p<0.001, p<0.001; respectively). In CD patients, the results showed that patients with anemia (P<0.01), Iron Deficiency Anemia (IDA) (p<0.001), CRP≥8 mg/L (p=0.046), and CDAI≥150 (p<0.001) had higher PLT, while in UC patients, those with anemia (p=0.018), CRP≥8 mg/L (p=0.045), and Mayo≥3 (p=0.029) had higher PLT. Univariate analysis showed that CDAI was positively correlated with PLT count (p<0.001), while hemoglobin (p=0.001) and age (p<0.001) were negatively correlated with PLT in CD. In UC patients, Mayo (p=0.001) and CRP (p<0.001) were positively correlated with PLT, while hemoglobin (p=0.002) was negatively correlated. Finally, by linear stepwise multivariate analysis, we clarified the positive relationship between PLT and CD (p<0.001) by eliminating the interference of hemoglobin, and determined the cut-off value of PLT as 298×109/L. For UC, we did not obtain similar results. CONCLUSIONS: PLT can be an indicator of disease severity in CD, while there is a lack of evidence regarding this finding in UC.

BACKGROUND: Elastic intramedullary nail is commonly used in the treatment of fractures of children, but few studies concern the elastic intramedullary nail for treating fractures in adults. OBJECTIVE: To investigate the repair effect of elastic intramedullary nail in the treatment of 22-A fracture in forearm of adults. METHODS: From January 2015 to April 2016, a total of 21 adult patients with the 22-A fracture (35 fractures) were treated with manipulative reduction and elastic intramedullary nail fixation in the First Affiliated Hospital of Guangzhou University of Chinese Medicine. The follow-up time was 12-18 months. Radiographs were taken and the guidance of the limb function training was given at regular intervals. The Andserson scoring system was used to evaluate the patients' forearm limb function. Fracture healing, elbow, wrist joint activity and forearm rotation were recorded. The satisfactory questionnaires were recorded. The patients were divided into three grades as satisfaction, general satisfaction and dissatisfaction; simultaneously, reasons were recorded. RESULTS AND CONCLUSION: (1) The Andserson scoring was satisfactory in 16 cases accounted for 76%, general satisfaction in 3 cases accounted for 14%, dissatisfaction in 2 cases accounted for 10%. (2) Wrist joint activity increased from (172±4)° before the operation to (181±3)° at the end of the follow-up. Elbow joint activity increased from (102±18)° before the operation to (124±13)° at the end of the follow-up. Forearm rotation activity increased from (84±11)° before the operation to (155±13)° at the end of the follow-up (P < 0.05). (3) In the follow-up of the 21 patients, 13 patients were satisfied with the result of surgery; 5 patients were generally satisfied; 2 patients were dissatisfied because the limited limb functions; and 1 patient was dissatisfied because of the nail irritability; the dissatisfaction rate accounted for 14%. (4) Elastic intramedullary nail can obtain affirmative effect in the treatment of adult 22-A fracture of the forearm; and clinical application should be based on the type of fracture.
ABSTRACT
@#Objective To compare the digital drainage system and the traditional drainage system in the patients after lung surgery, and to evaluate the advantages of digital drainage system. Methods A retrospective analysis of consecutive 42 patients with lung surgery between September 2016 and May 2017 in Beijing University International Hospital was done. There were 30 males and 12 females with a median age of 34 years ranging 19-81 years. After the surgery 21 patients adopted Thopaz digital drainage device (a DDS group), and the other 21 patients adopted traditional drainage (a TDS group). Duration of air leakage and chest tube placement, length of hospital stay, thoracic drainage volume within 48 h and hospitalization expenses in the two groups were compared. Results The patients in the two groups were all successfully discharged. Compared with the TDS group, duration of air leakage and chest tube placement and length of hospital stay significantly shortened in the DDS group (35.6±16.3 h vs. 48.2±20.1 h, P=0.02; 50.0±16.1 h vs. 62.0±20.4 h, P=0.03; 5.9±2.3 d vs. 7.8±3.5 d, P=0.02), and thoracic drainage volume within 48 h and hospitalization expenses showed no significant statistical difference between the two groups. Conclusion Using digital drainage system after lung surgery can significantly shorten the duration of air leakage and the postoperative drainage, at the same time, without increasing the overall hospitalization expenses.
ABSTRACT
@#Objective To analyze the early outcomes of 203 neonates with low birth weight (<2 500 g) undergoing cardiac surgery, and to analyze the causes of death during hospitalization. Methods From June 2003 to June 2017, medical records of 203 neonates with low birth weight undergoing congenital heart surgery in Guangdong General Hospital were reviewed retrospectively. There were 124 males and 79 females, including 151 premature infants. The average birth weight was 1 719±515 g, the average age at operation was 32.7±20.2 d and the average weight at operation was 1 994±486 g. The causes of death during hospitalization (including neonates given up on treatments) were analyzed. Results Totally 103 patients had pneumonia, 98 patients needed mechanical ventilation to support breathing and 26 patients needed emergency operation before operation. All patients undergoing congenital heart surgery were treated with general anesthesia with tracheal intubation, including 107 patients under non cardiopulmonary bypass (CPB) and 96 patients under CPB with a mean CPB time of 96.5±71.7 min and a mean aorta cross-clamp time of 51.8±45.5 min. The average postoperative mechanical ventilation time was 9.1±21.5 d and the average postoperative length of stay was 26.7±19.3 d. The major postoperative complications included pneumonia, anemia, atelectasis, septicemia, intrapleural hemorrhage, diaphragm paralysis and cardiac dysfunction. Twenty-nine patients died during hospitalization and the overall mortality rate was 14.3%. Four patients died in the operation room, 14 patients died 72 hours after operation and 2 patients were given up. The main causes of hospitalized death were low cardiac output syndrome, severe infection, disseminated intravascular coagulation disorder, acute renal failure and pulmonary hypertension crisis. Conclusion Overall, early cardiac surgery for low birth weight neonates is safe and effective. The difficulty of the cardiac surgery is the key to the prognosis. Strengthening perioperative management can improve the quality of operation and reduce the risk of mortality and morbidity during hospitalization.
ABSTRACT
We analyzed the epidemiological investigation results of the first case of human infected with avian influenza (H5N6) ,and summarized epidemiological characteristics of this case to provide reference to H 5N6 case screening and investiga‐tion in future works .We retrospectively described and analyzed the investigation progress ,specimen detection results of epi‐demic spot and intimate contact people ,and summarize epidemiological characteristics of this case .Result showed that the first case of human infected with H5N6 in Yunnan was a single case ,and did not showed human‐to‐human transmission .This case had contacts with wild bird and had birds’ market activity before diagnoses ;some environment specimen of birds market near patient’s home has detection results of H5N6 positive .This is a cases of local infection and did not show human‐to‐human transmission .From the investigation ,we could deduced that the transmission route is from birds to human or from birds to en‐vironment and then to human .
ABSTRACT
<p><b>OBJECTIVE</b>To study the clinical characteristics of ecotopic viral integration site-1 (EVI1) and BCR/ABL positive childhood leukemia.</p><p><b>METHODS</b>Clinical data of four children with EVI1 and BCR/ABL positive leukemia and eight children with BCR/ABL positive but EVI1 negative chronic myeloid leukemia (CML) were retrospectively analyzed.</p><p><b>RESULTS</b>In the four children with EVI1 and BCR/ABL positive leukemia, two were initially diagnosed with chronic phase of CML, one with accelerated phase of CML and one with high-risk acute lymphoblastic leukemia (ALL). There were no significant differences in clinical characteristics at diagnosis between the patients with EVI1 and BCR/ABL positive leukemia and BCR/ABL positive but EVI1 negative leukemia. CD33 and CD38 were highly expressed and t(9;22) abnormality was present in all patients with EVI1 and BCR/ABL positive leukemia. Two of the 3 children with EVI1 and BCR/ABL positive CML achieved complete remission one or three months after treatment. Acquired negative status conversion occurred for EVI1 but not BCR/ABL in one CML case. The 3 children with EVI1 and BCR/ABL positive CML survived 20, 13 and 14 months, respectively, without recurrence. The child with EVI1 and BCR/ABL positive ALL failed to achieve complete remission after the first course of treatment and discontinued further treatment.</p><p><b>CONCLUSIONS</b>Co-expression of EVI1 and BCR/ABL fusion gene can be found in childhood CML and ALL. The relatively rare leukemia has not significant difference respect to clinical characteristics. Prognosis of the disease needs to be determined by clinical studies with a larger sample size.</p>
