Objective To understand the types of drug use,medication habits,medical treatment behavior and drug management of urban families in Hefei,and to provide background information for drug safety education and scientific medical education.Methods The questionnaire design covers 32 issues,some teachers and parents of 2 training institutions,part of the staff of the 2 administrative institutions and the residents of the 3 residential areas were investigated.320 questionnaires were distributed,and valid questionnaires were collected from 306 copies.Results 96.1% of Hefei urban family had standing drugs,anti cold drugs was the highest proportion(87.3%),followed by antibacterial drugs(51.0%),the main channel was the purchase pharmacy(89.2%) and hospital(36.3%).When the family was ill,65.7% of the respondents first ate home medicine;the proportion of chosing a large hospital up to 83.3%.74.5% of respondents believed that antibiotics abuse.Up to 83.3% of respondents had been performed intravenous infusion therapy when illness,55.9% of the respondents thought intravenous infusion therapy most unnecessary,and only 5.9% of the respondents thought intravenous infusion therapy was dangerous.Consulting a doctor when they had a problem in 67.7%,followed by the internet query(44.1%) and to the pharmacy consultation(14.7%).40.2% of the respondents hoped to learn medical knowledge.Conclusion Hefei city of Anhui province has a high proportion of urban family with standing drugs,the purchase way is regular,and when the disease,first of all to eat home standing drugs,medical treatment prefers large hospital,most think most intravenous infusion is not necessary;They want to understand the medical knowledge,and hope to establish consultation channels.

BACKGROUND:Many studies concern the comparison of posterior laminectomy and instrumented fusion and posterior laminoplasty for multilevel cervical spondylotic myelopathy, but the sample size of many studies has limitations. There is lack of objective evaluation on advantages and disadvantages of two surgical methods. OBJECTIVE:To compare the efficacy and safety of posterior laminectomy and instrumented fusion and laminoplasty in the treatment of multilevel cervical spondylotic myelopathy. METHODS:A systematic search of al the studies published was conducted on the PubMed, Cochrane Central, EMbase, the ISI Web of Knowledge Database, CMB, CNKI, VIP and Wanfang databases. Randomized and non-randomized control ed trials that compared between posterior laminectomy and instrumented fusion and laminoplasty for multilevel cervical spondylotic myelopathy were identified. Meta-analyses were performed in postoperative Japanese Orthopaedic Association scores, cervical range of motion, cervical curvature index, incidence of C5 nerve root paralysis and incidence of axial symptoms. RESULTS AND CONCLUSION:(1) Fourteen studies involving 1 024 patients were included. Among the patients, 519 underwent laminectomy and instrumented fusion and 505 underwent laminoplasty. (2) The results of the meta-analysis indicated that, compared with laminectomy and instrumented fusion group, laminoplasty group had advantages of a lower incidence of C5 palsy [RR=2.24, 95%CI(1.33,3.75), Z=3.05, P<0.05] and smal degree of cervical rotation injury [SMD=-0.71, 95%CI(-2.21,-1.2), Z=6.63, P<0.05]. However, the two groups had no statistical difference in postoperative Japanese Orthopaedic Association score, cervical curvature index and the incidence of axial symptoms. (3) These results suggested that both laminectomy and instrumented fusion and laminoplasty were demonstrated to be effective for multilevel cervical spondylotic myelopathy. Laminoplasty had obvious advantages of decreasing the degree of cervical rotation injury and lowering incidence of C5 palsy. However, in the process of clinical diagnosis and treatment, the patient’s condition should be combined. The long-term clinical efficacy of the technology needs more clinical work to confirm.

Objective To detect the treatment effect of PC3 cells with triptolide on altering the expression of genes.Methods MTT assay was used to detec the inhibition of proliferation.Apoptosis was detected by Annexin-V/PI staining.RT-PCR was used to analyze the mRNA expressions of BCL-2,BAX,PIG3,P21,FAS,CASPASE3.Results Triptolide caused a time - and dose - dependent inhibition of cell proliferation,and IC50 of 24 h and 48 h were 18.3 ng/ml and 13.5 ng/ml,respectively.Compared with the 24 h group,the low concentration of triptolide(5 ng/ml,t =1.47,P ＞0.05)and the high concentration of triptolide ( 160 ng/ml,t =0.91,P ＞0.05)had no statistical significance in 48 h group,while 10 ng/ml( t =3.26,P ＜0.05),20 ng/ml( t =4.21,P ＜0.05),40 ng/ml( t =4.09,P ＜0.05),80 ng/ml( t =2.91,P ＜ 0.05 )had statistical significance.At the concentration of 18.3 ng/ml,triptolide induced PC3 cells apoptosis in a time - dependent manner.Compared with the control group,Anexin-V( + )/PI(-)was(5.42±2.21)％(t =3.52,P ＜0.05)in 6h,(13.51±3.37)％(t =6.53,P ＜0.01) 12h,(29.3 ±4.53)％ ( t =8.74,P ＜0.01) 24 h group separately,and it had statistical significance.RTPCR showed that 18.3 ng/ml triptolide up-regulated the mRNA expression of BAX and PIG3,down-regulated P21 and BCL-2.FAS and CASPASE3 did not show obvious changes.Conclusions Triptolide inhibits the proliferation of PC3 and induces apoptosis,and the changes of BCL-2,BAX,PIG3 and P21 may play an important role in the apoptosis of PC-3 cells.

Objective To explore the mechanism of LMWH therapy for SAP.Methods 48 wistar rats were random divided into 3 groups,sham group(S group),severe acute pancreatitis group(SAP group)and LMWH therapy group(H group).Serum amylase,IL-6,acinar cell apoptosis and the activity of NF-κB were detected and compared.Results The expression of amylase and IL-6 in SAP group was significantly higher than that in H group(P＜0.01).The apoptosis index of acinar cell in SAP group wag significantly lower than that in H group(P＜0.01),while the activity of NF-κB in SAP groupwas stronger than that in H group.Conclusions LMWH therapy may ameliorate SAP by inducing acinar cell apoptosis through suppressing the activity of NF-κB.

Objective To establish an enterovirus 71(EV71) infection model of tree shrew primary renal cells.Methods Tree shrew primary renal cells were obtained by trypsin digestion.After subculture and purification,EV71 virus was used to infect these primary cells.The culture supernatant of these EV71-infected cells was collected for virus titer detection at 1,2,4,6 and 8 days post-infection.The cells were collected for detection of EV71 VP1 protein by Western blot assay.Furthermore,the expression and location of VP1 protein in the infected cells were detected by indirect immunofluorescence assay.Vero cells were taken as positive control to evaluate the infectivity of EV71 virus to tree shrew primary renal cells.Results Morphologically,the cultured cells were proved to be majorly consisted of the primary renal cells after subculture and purification.The obtained primary cells were infected by EV71 virus.The virus titer was up to 1.3×106 TCID 50/mL during 48-96 h post-infection,proving that EV71 virus infected and proliferated in the tree shrew primary renal cells.Western blot showed that the viral VP1 protein was detected from infected primary cells at 2 to 8 d post infection.VP1 protein was also observed in the cytoplasm at 2 to 6 d post infection by indirect immunofluorescence.Compared with Vero cells,the infectivity of EV71 virus to tree shrew primary renal cells and its proliferation were confirmed.Conclusions Based on the successful establishment of cell culture of tree shrew primary renal cells,the infectivity to the obtained cells and proliferation of EV71 virus in the cells are confirmed.The model of EV71 virus-infected tree shrew primary renal cells is initially established.

BACKGROUND:The in vivo degradation process of chitosan/hydroxyapatite composite porous scaffolds is not very clear. Research on the effects of rat osteoblasts and degradation products is less.
OBJECTIVE:To analyze the biocompatiblity of rat osteoblasts with degradation products of chitosan/hydroxyapatite composite porous scaffolds.
METHODS:The second generation of cultured rat osteoblasts were respectively cultured in the extract of degradation products of chitosan/hydroxyapatite composite scaffolds (experimental group) and Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum (control group). At 2, 4, 6, 8, 10 days of culture, cel counting was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Alkaline phosphatase activity was measured by the recommended method of determination of the Federation, and total protein was determined by BCA method.
RESULTS AND CONCLUSION:The proliferation speed, alkaline phosphatase activity, total cel ular protein synthesis and ratio of alkaline phosphatase to total protein in rat osteoblasts cultured in the experimental group were significantly higher than those in the control group (P<0.05). This experiment showed that the degradation products of chitosan/hydroxyapatite composite porous scaffolds cannot only promote rat osteoblast adhesion, growth and proliferation, but also enhance its ossification function, with good biocompatibility.

Objective To explore the clinical efficacy of rectangle advancement flaps used in the reconstruction of skin defects around the Achilles tendon in children.Methods From May 2014 to June 2015,7 children with skin defects around the Achilles tendon were admitted to our trauma center.The areas of skin defect ranged from 3.4 cm × 2.7 cm to 5.5 cm × 4.0 cm.The integrity of Achilles tendon was preserved in 6 cases but the tendon insertion was partly disrupted in one case.The skin defects were reconstructed with self-designed rectangle advancement flaps after debridement.In the one case with the Achilles tendon partly disrupted,the contaminated tendon ends were excised before wound closure.The injured ankles were immobilized in plantar flexion with one 1.5 mm K-wire and plaster splint to decrease the postoperative tension of the flap.Results All the flaps survived completely by primary intention but local infection occurred in 2 wounds which was cured by second intention of dressing change.The follow-up periods ranged from 8 to 12 months (average,11.5 months).The scar around the flap was remarkable in 2 cases,but the flaps in the other cases appeared normal in terms of color and texture.The ankle function was satisfactorily normal in all the cases.Conclusion Our self-designed rectangle advancement flaps provide a simple,safe and reliable way to repair skin defects around the Achilles tendon in children.

373 adult cases with type Ⅱ diabetes mellitus were treated with, Shenqi Jiung Tang (SJT) Tablet and 108 cases with phenformin as control. The result showed that the symptoms were remarkably alleviated after treatment with SJT tablet. Blood glucose was decreased by 94.36％; 24-hour urine sugar was decreased by 85.79％ the total effective rate was 83.16％. The effect was significantly better than that of control group (p

Background: and Purpose Brainstem gliomas (BSGs) in adults are rare brain tumors with dismal outcomes. The aim of this study was to determine the clinical and genetic features in a series of BSGs and their association with the prognosis. Methods: Fifty patients who underwent a stereotactic biopsy between January 2016 and April 2018 at a single institution were collected. Data on clinicopathological characteristics were analyzed and factors associated with patient survival were identified using a Cox regression model. Results: The median age at diagnosis was 55.5 years, and 62% of the patients were male. Glioblastoma (44%) accounted for the largest proportion of BSGs, and oligodendroglioma (2 of 50) was rarely encountered. The IDH mutation (6 of 44) occurred infrequently in astrocytomas, and IDH-mutant tumors harbored both ATRX loss and MGMT promoter methylation at a relatively low level. Wild-type IDH astrocytomas were identified as having high rates of 1p/19q codeletion (5 of 38) and loss of heterozygosity 1p (8 of 38) or 19q (8 of 38) only. In diffuse midline glioma H3K27M mutant, MGMT promoter methylation occurred in three of four cases. Patients were offered radiotherapy and/or concurrent/adjuvant temozolomide chemotherapy, and their median survival time was 13 months. Multivariate analysis revealed that a low tumor grade, absence of tumor enhancement, duration of symptoms ≥3 months, Karnofsky performance status ≥70, and ATRX loss conferred a survival advantage. Conclusions Adult BSGs showed different molecular genetic characteristics, but also resembled supratentorial gliomas in their clinical features associated with oncological outcomes.
