Objective To explore an effective and hidden incision scar method for epicanthus correction. Methods 80 patients of bi-lateral single eyelid with epicanthus were divided into group A,group B and group C. Twenty-five patients with 50 eyes of group A received“Z” plasty correction of epicanthus,25 cases with 50 eyes of group B received the traditional“Y-V” plasty correction of epicanthus,30 cases with 60 eyes of group C treated with modified “Y-V” plasty correction of epicanthus. The curative effective was observed. Results Three groups were followed up for 6~24 months, the appearances of 25 patients in group A were significantly improved,of whom 2 cases had uni-lateral recurrence,8 cases with obvious postoperative scar. The eyelid shapes of patients in group B were natural after surgery,12 cases with obvious scar. all patients in group C were found no postoperative hypertrophic scars. Conclusion The three surgical treatment were effec-tive for epicanthus,but the design approaches of“Z” plasty correction and“Y-V” plasty correction are more complex,and postoperative scar is obvious,meanwhile the modified “Y-V” plasty correction is simple with incision hidden good shape scar formation.

Objective To observe the effect of virtual reality robotic hand on hand motor function and activities of daily living of pa-tients after stroke. Methods From June, 2015 to June, 2016, 32 patients with hand motor dysfunction were assigned into experimental group (n=16) and control group (n=16). The experimental group received training with virtual reality robotic hand and hand based rehabilitation, while the control group received hand based rehabilitation only, for four weeks. They were evaluated with Fugl-Meyer Assessment (FMA) of fingers and wrists and modified Barthel index (MBI) before and after treatment. Results The total score and the scores of items of FMA and MBI improved after treatment in the experimental group (Z>3.45 or t>3.45, P<0.01). The total score and the scores of the finger, wrist of FMA, and the scores of the eating, dressing and grooming of MBI improved in the control group (Z>2.07 or t>4.18, P<0.05). The total scores and scores of the items of FMA and MBI improved more in the experimental group than in the control group (Z>2.14 or t>3.20, P<0.05). Conclusion Virtual reality robotic hand training can promote the recovery of hand function and activities of daily living in patients af-ter stroke.

Objective: The Thinprep liquid-based cytology test(TCT) is a new technique applied to cytopathologic diagnosis in recent years.The purpose of this study was to analyze the diagnostic coincidence between lung puncture liquid-based cytology and histopathology.Methods: A total of 408 tissue specimens obtained by CT-guided percutaneous translung biopsy were observed under the optical microscope after fixation,embedding,sectioning and staining,and the cells in the washing fluid for puncture needles were detected by TCT.Then the diagnostic coincidence was analyzed between cytological and pathological biopsies.Results: Of the 408 cases detected by liquid-based cytology,148(36.3%) were diagnosed as cancer,32(7.8%) as suspected cancer,38(9.3%) as heterocyst and 190(44.9%) were negative,as compared with 183(44.9%),21(5.1%),22(5.2%) and 182(44.6%) by histopathology.The results showed a correlation between the two methods(P

Objective: To investigate the advantage of ThinPrep cytological test in tumor diagnosis by fine needle aspiration cytology. Methods: Using fine needle aspiration for smears,some of smears were made in conventional smears,the remains aspirating needles were washed with a transport washing solution.ThinPrep slides were made using the ThinPrep Processor. Results: In 84 cases FNA samples,49 cases were breast,29 cases were lymph node and 6 cases were others.Comparing with conventionally prepared specimens,ThinPrep processed samples showed the advantage in sensitivity or specificity.The lack of cellular debris,blood and exudates improve the ability to detect cellular abnormalities and speed up the time required for screening in ThinPrep processed samples.Rapid cell transfer from the sampling device to the transporing fluid containing the fixative ensure preservation of cell details with minimal artifactual changes. Conclusion: The use of Thinprep and by combination of FNAC and immunocytochemistry cytopathological diagnosis can be improved significantly.

Objective:Mutation in the gap junction beta 6 (GJB6) gene has been reported to be associated with an autosomal dominant disorder hidrotic ectodermal dysplasia (HED), characterized by congenital nail clubbing, alopecia and palmoplantar keratoderma. The aim of this study is to investigate relationship between genetic mutation in GJB6 and HED in an affected Chinese family.
Methods:We selected a Chinese HED family consisting of a total of 17 individuals including 8 HED patients (5 males and 3 females). The whole coding region of GJB6 was amplified by polymerase chain reaction and sequenced.
Results:Sequence analysis identified a heterozygous missense mutation c.31G>A (p.G11R) in GJB6 gene of affected individuals, but not in healthy individuals.
Conclusion:A c.31G>A (p.G11R) missense mutation in GJB6 gene is the genotypic characteristic for HED in Chinese population.

Objective To study the effects of the rehabilitation robot-assisted task-oriented training on the hand function in patients after stroke. Methods From June, 2015 to September, 2016, 35 inpatients suffering from stroke were randomly allocated to control group (n=17) and trial group (n=18). Based on the routine rehabilitation, the trial group accepted robot-assisted task-oriented training, while the control group accepted therapist-assisted task-oriented training, for two weeks. They were measured the active range of motion (AROM) of fingers, assessed with fingers motor of Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) invovled with hands before and after train-ing. Results The inpatients dropped three in the control group, two in the trial group. AROM of extension and flexion of all the fingers, the AROM of extension and total of three fingers of thumb, index and middle, and the total AROM of each finger improved in the trial group af-ter training (t>2.937, P<0.05), while the AROM of extension and flexion of all the fingers, AROM of extension, flexion and total of the fin-gers of thumb, index and middle, total AROM of the fingers of thumb, index and little improved in the control group after training (t>2.528, P<0.05);the AROM of extension and total of the fingers of thumb, index and middle, and the total AROM of fingers of thumb and index im-proved more in the trial group than in the control group (t>2.535, P<0.05). The scores of mass flexion, mass extension, opposition, cylinder grip, spherical grip and total score of FMA improved in the trial group after training (Z>2.000, P<0.05), while the scores of mass extension, opposition and the total score of FMA improved in the control group after training (Z>2.000, P<0.05). There was no significant difference between the two groups on the items and total scores after training (P>0.05). The scores of feeding, dressing, toilet transfers, bathing, groom-ing of MBI and the total score of them improved in the trial group after training (Z>2.041, P<0.05), while the total score of MBI improved in the control group after training (Z=-2.527, P<0.05). There was no significant difference between the two groups in the items and total scores after training (P>0.05). Conclusion The rehabilitation robot-assisted task-oriented training can improve AROM of hemiplegic fingers and grip function.

AIM: To investigate in vitro effects of cholecystokinin octapeptide(CCK-8) on the expressions of B7.1 and B7.2 and the costimulatory activity of T lymphocytes in unstimulated macrophages.METHODS: Mouse peritoneal macrophages were isolated and incubated with CCK-8(10-12-10-6 mol/L) for indicated time.The B7.1 and B7.2 expressions of murine peritoneal macrophages were analyzed by flow cytometry.CD4+T cells were isolated from mouse spleen using immunomagnetic beads,and cultured with 1/4 numbers of macrophages which were pretreated with CCK-8 and/or anti-B7.1 antibody,anti-B7.2 antibody,CCK1R antagonist CR1409,CCK2R antagonist CR2945 for 24 h.ConA was added into the culture medium to stimulate CD4+T cell proliferation.The proliferation was determined by measuring -TdR incorporation in a ?-scintillation counter.RESULTS: B7.1 and B7.2 expressions and costimulatory activity of peritoneal macrophages were enhanced by CCK-8 in a dose-dependent manner,and the maximal effects occurred at the concentrations of 10-9 mol/L to 10-7 mol/L.Anti-B7.2 antibody,but not anti-B7.1 antibody,reduced the modulatory role of CCK-8 on costimulatory activity.Both CR1409 and CR2945 reversed the effect of CCK-8 on costimulation,and the role of CR1409 was more significant.CONCLUSION: CCK-8 enhances macrophage costimulatory activity by upregulating B7.2 expression,which is mediated by CCK1R and CCK2R.CCK1R might be the major receptor responsible for the modulation of CCK-8 on costimulation.
