Objective To investigate the autophagy and the expression of its related genes in the peripheral blood mononuclear cells (PBMCs) of active systemic lupus erythematosus (SLE) patients.Methods Patients with newly onset or recently-diagnosed SLE (n=20) were enrolled.RA patients (n=10) and healthy blood donors (n=10) were used as controls.PBMCs from all subjects were immediately isolated by Ficoll-Hypaque density gradient centrifugation.And then monocytes were removed by wall sticking method.The morphology was observed using transmission electron microscopy (TEM).Messenger RNA (mRNA) expression of Beclin 1 and microtubule-associated protein 1-light chain 3 (MAPLC3) were determined by reverse transcription polymerase chain reaction (RT-PCR) and real-time quantitative RT-PCR respectively.Results TEM showed autophagic phenomenon in PBMCs from active SLE.On the mRNA level,expression of Beclin 1 and LC3 was significantly increased in fresh isolated SLE cells as compared with RA or healthy donor's PBMCs.Conclusion Based on these results,we can conclude that autophagy occurs in active SLE and the expression of its related genes is significantly higher in active SLE than in RA or normal controls.The enhanced autophagy may indicate its role in the pathogenesis of SLE.

Family environment plays an important part of the occurrence,development and outcome of attention-deficit/hyperactivity disorder (ADHD).Family and parenting interventions focus on the inter environment,aiming at forming an effective behavioral management,a better communication strategy,which will be conductive for child's symptoms as well as functions.Parents'emotion and self-efficacy as well as family functioning will be affected also.Common family and parenting skills include parent training and systematic family therapy,which respectively focus on behavior management and the whole family in view of system.The Multimodal Treatment Study of Children with ADHD (MTA) may have potential effects compared with single medical treatment and behavioral treatment.In China,parent training and structural family therapy have been proved to be effective.However,further consideration and experiments are necessary,especially on the long-time ending and individual management.

Objective To evaluate the feasibility and safety of vaginal enlarged amputation of cervix to treat patients with cervical cancer of stage Ⅰ a1 and cervical intraepithelial neoplasia grade Ⅲ(CIN Ⅲ)who were unfit for conization surgery.Methods From July 2002 to May 2007,patients with cervical cancer at stage Ⅰ a1,diagnosed by pathology after loop electrosurgical excision procedure(LEEP),large area CIN Ⅲ(the area of lesion≥3/4 on colposcopy),CIN Ⅲ coexisted with vaginal intraepithelial neoplasia (VAIN)in the superior segment of vagina,CIN Ⅱ-Ⅲ recurrence or with residual lesion,positive margin after conization of cervix,who wanted to preserve fertility and(or)corpus uteri were selected to receive vaginal enlarged amputation of cervix.Results Forty-eight eases including 5 with cervical cancer in stage Ⅰ a1,38 with large area CIN Ⅲ(9 with gland involvement),2 with residual lesion and 2 with positive margin after LEEP,1 recurrence after cold knife conization,received the procedure successfully.The median age was 34 years(range 27-40),median operation time was 60 minutes(range 30-100),median blood loss was 40 ml(range 5-300),and median hospital stay was 10 days(range 7-17).After follow-up 1-39 months,no patient had postoperative complications and recurrence,and all patients resumed normal menstrual cycle and sexual life.Condusion Vaginal enlarged amputation of cervix appears to be a safe and feasible procedure for patients with cervical cancer at stage Ⅰ a1 and CIN Ⅲ who are unfit for conization surgery.

Objective To explore the executive function profiles in adults with attention deficit hyperactivity disorder(ADHD)in a Chinese sample population. Methods We identified 68 outpatients fulfilling the diagnostic criteria for ADHD according to the Diagnostic and Statistical Manual of Mental Disorders-IV(DSM-IV)and 74 normal adults.All subjects completed clinical interview, Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) and Cambridge Neuropsychological Test Automated Battery (CANTAB). Results ADHD group had higher scores in all factors of BRIEF-A questionnaire compared with normal control (P<0.01). ADHD group had a higher score in SWM strategy score [(30.84±5.58)vs.(28.80±5.85), t=2.056,P=0.042]compared with control group. Compared with control group, ADHD group had a lower score in RVP total hits [37(33,41.75) vs.3(37,48), Z=-3.184,P<0.01]. Total correct rejections[(508(497.5,518)vs. 516(503,529.5),Z=-2.229,P=0.0260)]were significantly lower,while RVP total misses were significantly higher [(17 (12.25,21)vs.12(7,20),Z=2.293,P=0.022)].ADHD-RS-IV attention deficit score was positively correlated with SWM strategy while RVP total misses were negatively correlated with RVP total hits and RVP correct rejections.Working memory score in BRIEF-A was significantly correlated with the SWM strategy,RVP total hits, RVP total correct rejections and RVP probable of hit as well as RVP total misses. Conclusion Adults with ADHD have executive functioning deficits which is correlated with ADHD core symptoms.

Pancreatic cancer stroma plays a critical role in tumor progression, invasion, metastasis and resistance.Targeting tumor cell alone could not meet the demand for prolonging patients'' survival.Growing studies have laid emphasis on developing combined regimens between targeting pancreatic cancer stroma and chemotherapy, radiotherapy and immunotherapy.We are faced with some new opportunities in spite of the great challenges brought to the research and development of targeting drugs owing to the complicated stroma components, crosstalking signal pathways and abnormal angiogenesis of pancreatic cancer.In this article, recent advances in therapeutic strategies of targeting pancreatic cancer stroma are reviewed and analyzed from the aspects of extracellular matrix (ECM), cancer associated fibroblasts (CAFs) and vessels, in the hope of providing some novel ideas for targeting therapy against pancreatic cancer.

Objective: Bioinformatics methods were used to annotate the suspicious pathogenic genes of congenital microtia in detail, and construct the protein-protein interaction (PPI) networks to clarify the function and interaction of pathogenic genes, so as to predict the potential pathogenic genes. Methods: The pathogenic genes of congenital microtia were searched using the mouse genome informatics (MGI). The results were summarized into the STRING database to construct PPI networks. The Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were carried out. Results: Sixty-eight congenital microtia-related pathogenic genes such as FGF8, EYA1 and HOXA2 were searched by MGI. The PPI network contained 65 nodes and 174 edges. The average node degree was 5.35. The clustering coefficient was 0.437 and the PPI enrichment P = 0. The key node proteins were screened in PPI networks. The top ten were CTNNB1, FGF8, EGFR, BCL2, PAX6, FGF3, FGF10, WNT5A, FGFR1 and MAPK1. GO analysis and KEGG pathway analysis showed: the pathogenic genes were involved in the biological process of ear morphogenesis, ear development and embryonic organ morphogenesis. They also get involved in the molecular regulation, including sequence-specific DNA binding and regulatory region DNA binding. Expression of different genes were located in nucleus and other sub-microscopic cell components. Pathogenic genes were also involved in cancer pathway, melanoma, MAPK signaling pathways, RAS signaling pathways and other signaling pathways. Conclusions By using bioinformatics tools, we constructed the PPI networks of the congenital microtia pathogenic genes, and obtained detailed GO enrichment and KEGG pathway data. The key nodes contained the confirmed pathogenic genes of congenital microtia, which preliminarily proved the feasibility of the bioinformatics method in this study. We found some nodes were closely linked with FGF and WNT, which may be potential mutant genes of congenital microtia, although further study is needed.

Objective: To identify a pig model with bilateral external ear defects accompanied by aural atresia and investigate its application in plastic surgery. Methods: Erhualian×Shaziling F₂ pig inbreeding population was introduced, and examination of external ear morphology was conducted in all individuals. Temporal computed tomography scanning and mutational detection of HOXA1 gene were conducted in one affected and one normal individuals. Results: In Erhualian×Shaziling F₂ pig inbreeding population, there were 57 normal and 18 affected individuals among the 75 pigs. Affected subjects presented bilateral external ear defects accompanied by aural atresia; temporal computed tomography scanning showed bilateral aural atresia and dysplasiaof middle ear; and gene detection identified homozygous mutation of HOXA1 gene. Conclusions Pig model with HOXA1 gene homozygous mutation resembles human microtia at different levels. Our findings provide the theoretical basis for its application to study further pathological mechanism for human microtia.

Objective: To investigate the curative effect of auricular deformity repaired by concha cartilage. Methods: From January 2017 to June 2018, 15 cases with auricular deformities were repaired using the autologous concha cartilage which combined with the retroauricular flap or retroauricular fascia with skin grafting. 9 males and 6 females, aged 10-40 with an average age of 19; 3 cases of upper 1/3 traumatic auricle defect, 2 cases of congenital Stahl's ear, 5 cases of congenital cup-shaped ear and 5 cases of congenital cryptotia. Results: Total 15 patients were followed up for 12-18 months after the surgery. The area of concha cartilage resection was about 0.5 cm×1.0 cm. The shape and size of the repaired ears were similar to the healthy ear. The transplanted cartilages were not absorbed or deformed. The incision was healed well and retroauricular flap, retroauricular fascia, and skin grafting were preserved well without complications like hemorrhage, necrosis, and infection. Conclusions This method is harmless and simple, which has reliable and satisfactory effects on various auricular deformities.
