Objective To observe the effect of CT-aided scalp surrounding needling on infraction dementia by retaining long time. Methods 53 infraction patients following dementia were randomly divided into treatment group (n=26) and control group (n=27). The control group was treated with CT-aided scalp surrounding needling for 30 minutes, while the treatment group was treated with CT-aided scalp surrounding needling for 3 hours. The course was 8 weeks. The therapeutic effect was assessed by Mini-Mental State Examination(MMSE), Hasegawa Dementia Scale(HDS-R) and Activities of Daily Living (ADL). Results The scores of ADL, MMSE, and HDS-R improved obviously after treatment in two groups (P<0.05), and the treatment group was better than the control group (P<0.05). Conclusion CT-aided scalp surrounding needling by retaining long time may facilitate to enhance the clinical effect on infarction dementia.

Objective Studies show that the ERCC1 gene may be involved in secondary cisplatin resistance.This article aims to investigate the effects of shRNA targeting silencing excision repair cross-complementation group 1 (ERCC1-shRNA) on the proliferation and apoptosis of lung cancer A549/DDP cells treated with different concentrations of cisplatin.Methods Lung cancer A549/DDP cells were divided into a negative control, a blank control, an ERCC1-shRNA1, and an ERCC1-shRNA2 group.Human interfering RNA (RNAi) targeting the human ERCC1 gene was constructed and transfected into the A549/DDP cells using Lipofectamine 2000.The mRNA and protein expressions of ERCC1 in the A549/DDP cells were detected by real-time PCR and Western blot respectively, the proliferation-inhibition rate was assessed by MTT, and their cell cycle and apoptosis were determined by flow cytometry.Results ERCC1-shRNA was successfully constructed and transfected into the A549/DDP cells.Both the mRNA and protein expressions of ERCC1 were significantly lower in the ERCC1-shRNA1 (0.20±0.04 and 0.24±0.10) and ERCC1-shRNA2 (0.47±0.28 and 0.37±0.11) than in the negative control (0.96±0.12 and 1.32±0.13) and blank control groups (0.84±0.07 and 1.45±0.23) (P<0.01).Compared with the negative and blank control groups, the ERCC1-shRNA1 group showed a significantly decreased IC50 value (16.71±2.33 and 16.69±1.69 vs 7.78±0.54, P<0.01) and an increased proportion of G0/G1 phase cells ([72.87±3.23] and [71.75±4.56] vs [82.99±4.23]%, P<0.05), with the cell cycle arrested in the G0/G1 phase.The apoptosis rate of the cells in the ERCC1-shRNA1 group was remarkably lower after treated with cisplatin at the concentrations of 6.25 and 12.5 μg/mL than at 0 μg/mL ([8.17±0.65] and [11.91±1.41] vs [29.97±3.14]%, P<0.05).Conclusion ERCC1-shRNA can inhibit the proliferation and enhance the apoptosis of A549/DDP cells by silencing the expression of the ERCC1 gene.

Objective · To investigate the effect of metformin on insulin resistance (IR)-related metabolic parameters in olanzapine-bearing rats.Methods · Thirty female SD rats were randomly divided into metformin intervention group, olanzapine group and control group. During the first 6 weeks,5 mg /(kg·d) olanzapine was given to the two test groups . The control group was given the same amount of saline. From the 7th week, the intervention group began to combine with metformin 500 mg / (kg·d), while the olanzapine group combined with the same amount of saline, continuing for 4 weeks.At the end of 6th week and 10th week, intraperitoneal glucose tolerance and homeostasis model assessment IR index were assessed. Results · The area under the glucose tolerance curve (P=0.040) and the IR index (P=0.000) were significantly higher for the intervention group and the olanzapine group than the control group at the end of 6th week. At the 10th weekend, the glucose tolerance (P=0.015) and IR index in the intervention group were significantly lower than those in the olanzapine group (P=0.001). Conclusion · Metformin may rectify the impaired glucose tolerance and improve IR induced by olanzapine partly.

A 41-year-old female patient developed round,bright yellow patches on the left calvarial region without obvious precipitating factors 40 years prior to the presentation,which gradually grew to form plaques with age.Two years prior to the presentation,nipple-like lesions appeared in the calvarial and temporal region with an erythematous and wet surface; concurrently,black masses developed in the left temporal region and gradually enlarged with central ulceration but no subjective symptoms.At about 1 year of age,pitchy macules developed on the light tan patches located on the left jaw,posterior and anterior neck,trunk and upper limbs,and gradually increased in quantity and size with the involvement of the homolateral dorsal hand and gradual appearance of papules.Skin examination revealed two well-marginated,indurated,bright red neoplasms sized 3 cm × 2 cm and 2 cm × 1 cm respectively,with erosive and cauliflower-like surface; black or pink papules were scattered between these neoplasms.There was a ring-shaped black mass sized 1.5 cm × 1.5 cm in the left temporal region with central ulceration.Pitchy tough macules and papules were observed on the light tan patches located in the left cheek,lower mandible,posterior and anterior neck,protothorax,shoulder and back,upper limbs and dorsal hand.Based on the histopathology of multiple lesions,the cauliflower-like lesions on the head were diagnosed as syringocystadenoma papilliferum,the yellow plaques as syringocystadenoma papilliferum complicated by sebaceous adenoma,the black proliferative lesions in the temporal region as trichoblastoma accompanied by basal cell epithelioma,the black papuloid lesions and brown maculopapuloid lesions on the lower mandible as nevus spilus.The patient was diagnosed with skin adnexal tumor with multipotential differentiation (syringocystadenoma papilliferum,sebaceous adenoma,trichoblastoma and basal cell epithelioma)accompanied by nevus spilus.

Background and purpose:Rabs are members of Ras-related small GTPase superfamily. Rab27A is a unique member in the Rab family and has specific implications in human genetic diseases. We studied the potential role of Rab27A in proliferation, distribution of cell cycle, apoptosis and invasion of breast cancer cells and its mechanism(s). Methods:The eukaryotic expression vector containing Rab27A open reading frame (ORF) pcDNA3.1(+) - Rab27A was constructed and transfected into MDA-MB-231 breast cancer cells. Then we detected the changes in terms of cell growth, cell cycle distribution, apoptosis and in vitro invasion capability before and after transfection. We also applied RT-PCR to investigate the molecular basis.Results:① The expression of Rab27A was increased as invasive and metastatic ability increased in four human breast cancer cell lines. ② Overexpression of Rab27A can promote breast cancer cells to grow faster, increase the proportion of S phase cells, avoid apoptosis and invade in vitro. ③ Rab27A transfectants constitutively enhanced the expression of Cyclin D1, MMP-7 and MMP-9 in MDA-MB-231 cell lines, on the contrary, that of p16 were down-regulated constitutively. Reduced Rab27A expression by RNAi down-regulated the expression of Cyclin D1, MMP-7 and MMP-9, and up-regulated p16 expression.Conclusions:Rab27A can stimulate breast cancer cells to proliferate, increase the proportion of cells in S phase,avoid apoptosis and invade in vitro by regulating the expression of Cyclin D1, MMP-7, MMP-9 and p16.

Objective:To evaluate the feasibility and safety of device closure of patent ductus arteriosus (PDA)using only venous access under echocardiography guidance alone.Methods:A total of 102 consecutive pediatric patients underwent transcatheter PDA closure without arterial access,under the guidance of only echocardiography.The patients were followed up by clinical examination,electrocardiogram,and echocardiogram at 1,3,6 12,and 24 months.Results:Transvenous PDA closure under echocardiographic guidance was successful in 99 (97.1%)patients.There were no acute procedural complications or severe adverse events.The duration ranged from 10 to 65 minutes (median,21 minutes).Immediate complete closure of PDA was achieved in 87 patients (87.9%),and 100% of the patients were completely closed after 24 h.There were no severe adverse events in the period of 1-24 months (median,12 months) follow up.Conclusion:Transvenous PDA closure without fluoroscopy avoids radiation exposure,contrast agent usage and potential arterial complications.It can be used as an alternative procedure,especially for children.
