BACKGROUND:Since cannulated screw has been applied to femoral neck fracture, it is not uncommon that the screw wear penetrates or refunds. What factors affect the stability of cannulated screw for treatment of femoral neck fractures in adults remains unclear. ＜br> OBJECTIVE:To explore factors related to internal fixation failure by cannulated screws in treatment of adult femoral neck fracture and improve the stability of the adult femoral neck fracture by cannulated screws. ＜br> METHODS:A total of 92 adult patients of femoral neck fracture were treated by cannulated screws in our department between June 2007 and June 2011. Their data were retrospectively analyzed. According to clinical information and fol ow-ups, we selected factors such as age, gender, Garden type of fracture, preoperative skeletal traction, timing of surgery, Garden index, standards of pedicle screws, pedicle screw shapes, partial weight bearing time and postoperative complications, which may affect the success rate of cannulated screws for ＜br> treating femoral neck fracture. The selected factors were then grouped and assigned, after unrelated factors were excluded by one-way χ2 analysis, multiariable Logistic regression analysis was performed. ＜br> RESULTS AND CONCLUSION:The involved 92 patients were fol owed up for 18-72 months. According to Harris assessment criteria, hip function was excellent in 28 cases, good in 25 cases, fair in 17 cases, and poor in 22 cases at the final fol ow-up, the excellent and good rate was 58%. Radiographic results showed that, the patients were divided into two groups according to the presence of the displacement, GardenⅠ (n=22) and GardenⅡ (n=29) as a group, and Garden Ⅲ (n=25) and Garden Ⅳ (n=16) as the other group, the fixation failure rate was 12%and 39%, respectively. In normol and abnormal Garden Index groups, the fixation failure rate was 16%and 59%, respectively. In nail position standards and non-attainment standards groups, the fixation failure rate was 19%and 70%, respectively. In the complication and non-complication groups, the fixation failure rate was 14%and 55%, respectively. These factor groups showed significant differences (P＜0.05). Multiariable Logistic regression analysis showed that, Garden type of fracture, Garden index, standards of pedicle screws, and postoperative complications are the risk factors for internal fixation failure using cannulated screws in treatment of the adult femoral neck fracture.

BACKGROUND: Greatly importance has been attached to ceramic-on-ceramic bearing surface due to its excel ent wear resistance. But the risks of squeaking and ceramic fracture also go with it. Up til now, the choice between ceramic-on-ceramic and ceramic-on-polyethylene bearing surfaces in primary total hip arthroplasty remains controversial. OBJECTIVE: To compare the clinical outcomes and safety between ceramic-on-ceramic versus ceramic-on-polyethylene bearing surfaces in total hip arthroplasty based on meta analysis. METHODS: We electronical y searched databases including PubMed/Medline, Embase, Web of Science, Cochrane Col aboration database, Chinese Biomedical Literature Database (CBMdisc) and China National Knowledge Internet for randomized control ed trials on the comparison between ceramic-on-ceramic versus ceramic-on-polyethylene bearing surfaces in total hip arthroplasty from inception to January 2015. References of the included studies were also retrieved. Investigators severely selected the studies, extracted data and assessed the quality according to the inclusion and exclusion criteria. Then, meta-analysis was performed using RevMan 5.2 software. RESULTS AND CONCLUSION: Nine randomized control ed trials were included, involving 1 231 hips with ceramic-on-ceramic prosthesis and 932 hips with ceramic-on-polyethylene prosthesis. Meta analysis showed that both bearing surfaces achieved satisfied function recovery. But ceramic-on-ceramic had significantly increased risks of squeaking and ceramic fracture, meanwhile ceramic-on-polyethylene showed significantly higher wear rate. There were no significant differences in intra- or post-operative dislocation, osteolysis and other complications and prosthesis failure with any reason between two bearing surfaces. These results suggest that during the short- to mid-term fol ow-up period, no sufficient evidence can tel that ceramic-on-ceramic was obviously super than ceramic-on-polyethylene. Long-term fol ow-up is required for further evaluation.

Neonatal chylothorax is a common cause of neonatal congenital pleural effusion and is often caused by the accumulation of chylous fluid in the thoracic cavity due to the rupture of the thoracic duct and its branched lymphatic vessels for a variety of reasons. Neonatal chylothorax caused by malignant tumors is extremely rare, and this is the first case of neonatal mediastinal neuroblastoma with chylothorax in China. The boy was found to have pleural effusion in the left thoracic cavity in the uterus, and experienced apnea at birth, as well as dyspnea and cyanosis as the main manifestations after birth. He was diagnosed with left chylothorax based on conventional biochemical analysis of pleural effusion. After the treatment including persistent chest drainage and symptomatic and supportive treatment, the drainage of the left thoracic cavity reached a volume of 90-180 mL per day. Neonatal refractory chylothorax was considered. Chest radiograph on day 13 after birth showed lesions in the upper left lung field, and contrast-enhanced plain CT scan of the chest suggested the possibility of posterior mediastinal neuroblastoma. The autopsy confirmed giant posterior mediastinal neuroblastoma (poorly differentiated), which involved the C7-T6 spinal canal and the nearby erector spinae, with a small amount of tumor tissue in the liver and both adrenal glands. Mediastinal tumor is considered the underlying cause of chylothorax in this case.

Objective:To evaluate the gene mutation profile and prognostic significance of adult cytogenetically normal acute myeloid leukemia (CN-AML) with CEBPA-bZIP mutation. Methods:Targeted sequencing was implemented on the diagnostic bone marrow DNA samples of 141 adult CN-AML subjects with CEBPA-bZIP mutation. The nomogram model for leukemia-free survival (LFS) rate was generated by combining genetic abnormalities and clinical data. Risk stratification was conducted based on prognostic variables and the effect of risk-adjusted consolidation therapy was investigated by Kaplan-Meier method. Results:Four variables were finally included in our nomogram model after multivariate Cox analysis,and an equation for risk score calculation was obtained,risk score=1.3002×white blood cell (WBC) (≥18.77×109/L)+1.4065×CSF3R mutation positive+2.6489×KMT2A mutation positive+1.0128×DNA methylation-related genes mutation positive. According to the nomogram model,patients were further divided into low-risk group (score=0,n=46) and high-risk group (score>0,n=95). Prognostic analysis showed that the 5-year LFS rate,5-year overall survival (OS) rate,and 5-year cumulative incidence of relapse (CIR) of patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the high-risk group were 93.5％,97.1％,and 3.5％,while those in patients who received maintenance chemotherapy were 32.9％,70.5％,and 63.4％,respectively. The differences were statistically significant (all P<0.05). Allo-HSCT could significantly improve the prognosis of patients in high-risk group. However,no corresponding benefit was observed in the low-risk group. Conclusion:Adult CN-AML with CEBPA-bZIP mutation has a complex co-mutation pattern. The nomogram model based on mutations of CFS3R,KMT2A and DNA methylation-related genes together with WBC count can further divide this subset of patients into a relatively low-risk group and a relatively high-risk group. For individuals in the high-risk group,allo-HSCT is proposed as post-remission therapy. The above data will benefit the prognosis estimation and treatment decision for adult CN-AML with CEBPA-bZIP mutation.

To analyze the genomic sequence characteristics of a human Echovirus 9(ECHO-9) strain isolated from a child with Hand-foot-mouth disease (HFMD) in Kunming, Yunnan Province, in 2010. The complete genome sequence of a human echovirus 9 strain, MSH-KM812-2010 was determined. As other human enterovirus, its genome was 7,424 nucleotides (nts) in length and encoded for 2,203 amino acids (aas). In comparison to other human enteroviruses, MSH-KM812-2010 strain had the highest homology with other strains of human echovirus 9 in structural genomic regions and more homologous to other serotypes of B specie than to human echovirus 9 in non-structural genomic regions. Phylogenetic analysis based on complete VP1 gene revealed that the sequences of human echovirus 9 segregated into three distinct clades A, B and C with more than 15. 0% diversity between clades. All Chinese isolates belonged to the same clade. RDP3 and Blast revealed evident recombination in non-structural genomic regions. This report is the first to, describe the complete genome of the human echovirus 9 in China and provide an overview of the diversity of genetic characteristics of a circulating human echovirus 9.

Eight full-length genes of an avian influenza virus Chinese isolate of H9N2 subtype, A/Chicken/Guangdong/HL/2006 (H9N2) (abbreviated as Ck/GD/HL/06), were amplified by RT-PCR, including the 5' and 3' non-coding region. All the genes were cloned and sequenced. The phylogenetic analysis results showed the HA gene of Ck/GD/HL/06 was located in the same phylogenetic clade as Dk/HK/Y280/97 (H9N2), while the Dk/HK/Y280/97-like viruses had been predominately isolated from chickens in mainland China. After the analysis of glycosylation sites and receptor-binding sites in the HA, it was shown that the HA of Ck/GD/HL/06 exhibited the common feature of H9 subtype avian influenza virus isolated from China, but the leucine (Leu) residue at the amino acid position 226 indicated the potential of binding with SA alpha,2-6 receptor. The three internal genes of Ck/GD/HL/06 (PB1, PA and NP) had the highest nucleotide identity with A/Viet Nam/1203/2004 (abbreviated A/VN/1203/04) isolate, which was shown to be transmitted from chickens to human and caused lethal infection in human. No analogous H9N2 strains was reported in previous studies. Based on the high similarity of Ck/GD/HL/06 three genes to A/VN/1203/04, it was suggested that the possibility of generating new highly pathogenic H5N1 AIVs by recombination was worthy of our attention. Further studies should be needed for molecular epidemiologic surveillance of H9N2 AIV in the south China for a long time.

OBJECTIVE: To compare the efficacy of domestic and imported caffeine citrate in the treatment of apnea in preterm infants. METHODS: A total of 98 preterm infants with a gestational age of 28 - <34 weeks between April 2018 and December 2019 were enrolled. They were randomly administered with domestic (n=48) or imported caffeine citrate (n=50) within 6 hours after birth. The therapeutic effects, complications, adverse effects and clinical outcomes were compared between the two groups. RESULTS: There were no significant differences in the incidence of apnea within 7 days after birth, daily frequency of apnea, the time of apnea disappearance, the failure rate of intubation-surfactant-extubation strategy, the time of non-invasive assisted ventilation, the duration of oxygen therapy, the duration of caffeine citrate therapy, the length of hospital stay, blood gas analysis results, liver and kidney function testing results between the two groups (P>0.05). There were no significant differences in the incidence of complications and the mortality rate between the two groups (P>0.05). There was no significant difference in the incidence of adverse effects between the two groups (P>0.05). CONCLUSIONS The efficacy and safety of domestic caffeine citrate in the treatment of apnea are similar to those of imported caffeine citrate in preterm infants.

PURPOSE: This study differentiates patient and care delays of breast cancer and explores the related factors as well as the associations with the prognosis in Guangzhou, a southern city of China. METHODS: A cohort of female incident breast cancer patients (n=1,551) was recruited from October 2008 to March 2012 and followed up until January 1, 2016 (n=1,374) in the affiliated hospitals of Sun Yat-sen University. The factors associated with patient and care delays were analyzed with multivariable logistic models. Cox proportional hazards regression models were constructed to estimate the impacts of the delays on the prognosis. RESULTS: There were 40.4% patient delay (≥3 months) and 15.5% care delay (≥1 month). The patient delay, but not the care delay, was significantly related to the clinical stage and consequently worsened the prognosis of breast cancer (hazard ratio, 1.45; 95% confidence interval, 1.09 to 1.91 for progression-free survival). The factors related to an increased patient delay included premenopausal status, history of benign breast disease, and less physical examination. CONCLUSION: Patient delay was the main type of delay in Guangzhou and resulted in higher clinical stage and poor prognosis of breast cancer. Screening for breast cancer among premenopausal women may be an effective way to reduce this delay.
