Objective To apply a hand function laserimager to evaluate the effect of acupuncture on hand dysfunction after stroke. Meth-ods From January to June, 2016, 18 stroke patients with upper limb dysfunction were divided into control group (n=9) and acupuncture group (n=9). The control group received routine medication and rehabilitation, while the acupuncture group received acupuncture in addi-tion. They were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) of upper limb motor function and modified Bathel Index (MBI) before and after three-week treatment, while the region of interest (ROI) of their hands was tested with the hand func-tion laserimager. Results The scores of MAS and FMA improved after treatment in both groups (t>4.44, P<0.01), and improved in the score of MBI in the acupuncture group (t=3.95, P<0.01). The scores of MAS, FMA, and MBI improved more in the acupuncture group than in the control group (t>3.17, P<0.01). Meanwhile, the scores of ROI decreased in the affected hands after treatment (t>7.78, P<0.001), and de-creased more in the acupuncture group than in the control group (t=-2.23, P<0.05). No significant difference was observed in the scores of ROI of the unaffected hands (t=-0.11, P>0.05) between groups. Conclusion The hand function laserimager, which responds to the blood perfusion of the hand, can be used as a tool to evaluate the hand function.

ObjectivesTo present the current condition of non-invasive ventilation in newborns in the last ifve years in China, to describe the probable research trends of this ifeld, and to provide the possible research directions in future.Methods Using co-word analysis, the keywords “neonate” and “non-invasive ventilation” were searched in the CNKI database. The search results included 457 articles. Then the relation matrix was built by Excel 2010. Finally the visualized network was drawn by Ucinet 6.3.ResultsNasal continuous positive airway pressure (nCPAP) is primarily for the treatment of neonatal respiratory distress syndrome (NRDS) in China. Meanwhile, nasal intermittent positive pressure ventilation (nIPPV) and bilevel positive airway pressure (BiPAP) are gradually applied in clinic. The application scope of non-invasive ventilation is expanding. Besides the neonatologists, nurses are also paying close attention to non-invasive ventilation.ConclusionsThe visualized network, successfully built by Netdraw, relfects the hot topics and current condition in this ifeld.

OBJECTIVETo investigate the effect of hypoxia on the human pulmonary artery smooth muscle cells two pore domain potassium channels TASK-1 and the regulation of non-receptor tyrosine kinase c-Src in this process.

METHODSThe cultured human pulmonary artery smooth muscle cells (hPASMCs) were divided into: normal group, hypoxia 30 minute group, hypoxia 6 hours group and hypoxia 48 hour group, and hypoxia 48 hour + PP2 group, hypoxia 48 hour + PP3 group, hypoxia 48 hour + bpV group. Flow cytometry was used to analyze the cell cycle, RT-PCR and Western blot technique were carried out to detect the expression changes of TASK-1 mRNA and protein in different groups.

RESULTS(1) Cell Cycle Show: Compared with normal control group, with prolonged hypoxia, the percentages of hPASMCs in S phases of cell cycle were increased. While compared with hypoxia 48 hour group, the percentages of hypoxia 48 hour + PP2 group hPASMCs in S phases of cell cycle were decreased. The expression of TASK-1 mRNA on hPASMCs in acute hypoxia 6 hour group was increased, while the expression of TASK-1 protein on hPASMCs in the acute and chronic hypoxia group was decreased, and the expression of TASK-1 mRNA on hPASMCs in the chronic hypoxia group was decreased; After pre-incubation of a potent and selective inhibitor of the Src family of protein tyrosine kinases PP2, the expression of TASK-1 mRNA and protein in hypoxia 48 hour group was increased, however after pre-incubation of the inhibitor of the Src family of protein tyrosine phosphatase bpV, the expression of TASK-1 protein in hypoxia 48 hour group was decreased.

CONCLUSIONHypoxia promotes human pulmonary artery smooth muscle cell proliferation, and non-receptor tyrosine kinase c-Src may participate in the expression of two pore domain potassium channels TASK-1 regulated by hypoxia. Therefore, we hypothesized that TASK-1 channels and c-Src participatein the acute and chronic hypoxic human pulmonary vasoconstriction.

Objective To review the clinical experience of reconstruction of pulmonary artery(PA) by a pateh of autologus pericardium or azygous venae for non-small cell lung cancer. Methods Between March 1992 and August 2009, 62 patients with locally advanced central lung cancer received sleeve resection and reconstruction of PA. According to PTNM classification, 4 patients were in stage Ⅱb, 46 in stage Ⅲa and 12 in stage Ⅲb. 17 patients had induction chemothoerapy. Sleeve lotrate the PA, the surgical procedures included partial PA tangential resections and reconstructions by a pateh of autologous azygous venas in 18 cases , a patch of autologous pericardium in 38 cases and a complete PA sleeve resection reconstructios by a custom-made autologous pericardial conduit interposition in 6 cases. Partial superior vena cava tangential resctions and reconstructions were performed in 5 patients by a patch of autologous pericardium or azygous venae. 47 patients received pstoperative chemotherapy and 19 had radiotherapy. Results There was 2 early postoperative deaths(3.2%). The cause of death was bronchial anastomotic leak led to respiratory failure in 1 case and severe arrhmia led to heart arrest in 1. No cancerous tissue of all resection margins are checked by frzen section histology and examination of resection specimens in the surgical pathology laboratory. The postoperative complications occurred in 11 patients(17.7%) and all of them recovered uneventfully.Roentgenography, flexible bronchoscopy and echocardiography were in normal range in the remaining 60 patients with no bronchial anastomosis stenosis or vascular thombosis before discharge and at 2-6 months after surgery. The mean follow up time was 49.5 months (6-210 months). The overall 1, 3, 5 and 10 yerr survival rates were 80.2%, 44.7% ,31.4% and 23. 1%, respectively. Conclusion Reonstruction of PA by autologous pericardial patch or autologous azygos vein patch is a safe and effective technique for locally advanced lung cancer.For extended circumferential defects of PA,the autologous pericardial conduit interposition could bue used for reconstruction.

Objective To evaluate the clinical values of complement C3 and C4 and C-reactive protein (CRP) in the differential diagnosis of disease relapse and infection in systemic lupus erythematosus (SLE). Methods Sixty-three hospitalized SLE patients during 2011-2014 were retrospectively analyzed in this study. Patients were grouped according to the presence of infection and SLE disease activity index (SLEDAI). The laboratory findings, including CRP, erythrocyte sedimentation rate(ESR), complement and immunoglobulin were compared between the infected group (n=20) and non-infected group (n=43) and the flare group (n=44) and inactive group (n=19). Correlation analysis was also made between SLEDAI and serum markers. Results The levels of CRP, ESR, IgA, and SLEDAI in the infection group were significantly higher than those of the non-infection group (P<0.05). The levels of ESR and IgG in the flare group were significantly higher and C3 was significantly lower than those in the inactive group (P<0.05). Correlation analysis found that C3 was negatively correlated with SLEDAI (r=-0.666, P<0.01), but CRP was not correlated with C4(r=0.073, r=0.143; P>0.05). Conclusion CRP is elevated when SLE patients have infection, but C3 and C4 have no decrease or only with slight decrease. During flare of SLE patients, C3 is decreased and C4 has no obvious decrease, with CRP not elevated or slightly elevated. It is indicated that C3 and CRP are valuable in the differential diagnosis of disease relapse and infection in SLE.

Objective To investigate the clinical value of proximal femoral nail antirotation ( PFNA) in treatment of intertrochanteric fractures.Methods From April 2007 to July 2009,112 patients with intertrochanteric fractures were treated by using PFNA.There were 34 males and 78 females,at mean age of 76 years.Of all,80 patients were with type 31-A2 fracture and 32 with type 31-A3 fractures according to AO classification.According to Singh index classification,there were 4 patients at grade Ⅰ,21 at grade Ⅱ,70 at grade Ⅲ and 15 at grade Ⅳ.The fracture was caused by low-energy injury in 97 patients and by high-energy injury in 15.The Salvati-Wilson score was used to evaluate the hip function postoperatively.Results Ninety patients received 12-24 months follow-up (average 18.6 months).The Salvati-Wilson score was (29.98 ± 5.18 ) points.The result was excellent in 41 patients,good in 40,fair in 6 and poor in 3,with excellenct rate of 90％.The introduction of the nail in operation was difficult in 22 patients,of which 3 patients suffered femoral cortex rupture.Displacement or separation of the fracture segments occurred in 34 patients and distal locking difficulty in nine during the screw blade tapping process.Local complications included hip pain in 21 patients,thigh pain in 4,apparent coxa vara in 2 and delayed healing in 7.There were no cutting-out or femoral shaft fractures no matter what type of Singh index was.The systemic complications included cardiovascular and cerebrovascular disease in one patient,pulmonary infection in four,deep vein embolism in one and perineum congestion or swelling in seventeen.Conclusion PFNA is effective in treating intertrochanteric fractures especially osteoporotic fractures,but delayed healing of the fractures and the mismatch between the intramedullary nail and the proximal femoral morphology remain to be addressed.

OBJECTIVETo investigate the vascular supply of intrinsic muscles of foot and anatomic basis for muscular flap design.

METHODSA radiopaque injectate (lead oxide-gelatin mixtures, 26 ml/kg) was injected into 10 fresh cadavers. The dissected regions were photographed and each intrinsic muscles on the foot was removed and radiographed. The number, type, diameter of vascular branches of muscles and their distributions were observed. The area of the vascular territory supplied by each source vessel was calculated using Scion Image for Windows software.

RESULTSThere were significant architectural differences among the intrinsic muscles. The muscles length varied from 22.5mm to 116.2mm [average, (66.1 +/- 23.2)mm]. The measured fiber length were relatively consistent, ranging from 14.2 mm to 27.5 mm [average, (20.2 +/- 4.5)mm]. There are 63 vascular branches into the 23 foot muscles, each muscle having average branches of 3.2 +/- 0.8. The average diameter of branches, the length and width of each vascular territorial area is (0.8 +/- 0.3) mm, (2.2 +/- 0.8) cm, and (0.9 +/- 0.4) cm, respectively. Other findings included that some muscles were not present in some cadavers.

CONCLUSIONSThe blood supply of intrinsic muscles of foot is abundant with different diameter and distributions of branches. There is an anatomic basis for muscular or musculoosseous flap design. There are 7 intrinsic muscles with large and reliable vascular supply which can be chosen as muscular flaps.

OBJECTIVETo investigate the effects of butyl alcohol extract of Baitouweng decoction ( BAEB) on yeast-to-hyphae transition of Candida albicans isolates from vulvovaginal candidiasis (VVC) in alkaline pH.

METHODSerial 2-fold dilution assay was used to determine the minimal inhibitory concentrations (MICs) of Baitouweng decoction extracts against C. albicans isolates from VVC, XTT assay was applied to determine the metabolic activity of C. albicans hypha treated by BAEB for 6 h. The morphological change of C. albicans treated by BAEB was inspected at different pH by inverted microscope, fluorescence microscope, scanning electron microscopy (SEM). Solid agar plate and semi-solid agar were utilized to evaluate colony morphology and invasive growth of C. albicans, respectively. Quantitative Real-time PCR (qRT-PCR) was adopted to observe the expressions of hyphae-specific genes including HWP1, ALS3, CSH1, SUN41 and CaPDE2.

RESULTThe MIC of BAEB against C. albicans is less than that of other extracts; hyphae grow best at pH 8. 0; 512 mg · L(-1) and 1,024 mg · L(-1) BAEB could inhibit formation of hyphae and influence colony morphology. When treated by 512 mg · L(-1) and 1,024 mg · L(-1) BAEB, the colonies became smooth; while by 0 and 256 mg · L(-1) BAEB, the colonies became wrinkled. In semi-solid agar, the length of hyphae decreased steadily as the concentration of BAEB lowered. The expression of HWP1, ALS3, CSHl, SUN41 were downregulated by 5.12, 4.26, 3.2 and 2.74 folds, and CaPDE2 was upregulated by 2.38 fold.

CONCLUSIONBAEB could inhibit yeast-to-hyphae transition of C. albicans isolates from VVC in alkaline pH.
