ObjectiveTo study the effects of early rehabilitation on symptom, range of motion (ROM) and motor function of upper extremity of patients with shoulder-hand syndrome after stroke.Methods47 patients were divided into two groups,early rehabilitation group and non-early rehabilitation group.Two groups were treated with comprehensive rehabilitation. The passive ROM, the pain and motor function of affected limb was assessed by Fugl-Meyer Assessment.The evalution was done in pre-treatment and post-treatment respectively. Results1.The passive ROM decreased and the pain of affected limb of the early rehabilitation group were less than the non-early rehabilitation gronp when the shoulder-hand syndrome occour.2.After comprehensive rehabilitation treatment,their clinical symptom ROM and motor function of upper extremity impoved significantly in patients with shoulder-hand syndrome after stroke( P<0.05).The early rehabilitation treatment has better effects. Conclusions The early rehabilitation treatment could decrease the degree of their passive ROM decrease and the pain of affected limb in patients with shoulder-hand syndrome after stroke,and the patients who accepted earlyrehabilitation seemed easly to improve by comprehensive treatment.

Objective To construct cDNA entry library and cDNA expression library of Armillifer agkistrodontis (A.) nymphs and make a preliminary immunoscreening for the cDNA expression library.Methods The nymphs were collected from the Kunming mice infected experimentally with A.agkistrodontis eggs and the total RNA were extracted from the nymphs using TRIzol Reagent.After purifying the mRNA,the synthesized cDNAs were cloned into the donor vector pDONR222 by BP reaction of Gateway technology and the recombinants were transformed into the DH10B cells by electroporation,the cDNA entry library was obtained.Next,the expression vector pDEST17 was ligated with entry clones by LR reaction,and the recombinants were transformed into the BL21 (DE3) cells.Hence,the cDNA expression library was constructed.Then,the expression library was immunoscreened with the mixed sera of mice infected with A.agkistrodontis,and the insertions of positive clones were sequenced.After that,the open reading frame(ORF) of positive slone sequence,the homology of the screened genes and their encoded proteins were analyzed by Finder and BLAST (basic local alignment search tool) program of National Center of Biotechnology Information(NCBI),and the discovered new genes were submitted into the GenBank.Besides,the physico-chemical properties,secondary structure and B cell epitopes of encoded proteins were also analyzed by bioinformatics software.Results The average titer and total clones of the cDNA entry library were 1.45 × 105 CFU/ml(colony-forming unit,CFU) and 1.74 × 106 CFU,respectively,and the range of fragment length of the inserted cDNA was between 0.2-4.0 kb,with an average of 1.4 kb.The total clones of cDNA expression library were 1.00 × 105 CFU,and the fragment length of the inserted cDNA was between 0.3-2.2 kb,with an average of 1.0 kb.Five positive clones,coded S1,S5,A1,D1 and F1,respectively,were obtained through preliminary immunoscreening.The sequence and homology of the five positive clones were sequenced and analyzed by BLAST program.No significant similarities were found in pentastomida species,which meant that they were all novel genes of A.agkistrodontis.The gene sequences were submitted to GenBank,with the accession number from JQ180451 to JQ180455.Also,results obtained by bioinformatics software showed that the predictive encoding proteins were all potential to be valuable recombinant diagnostic antigens.Conclusions The cDNA library of A.agkistrodontis nymphs is successfully constructed,and five new genes of A.agkistrodontis are discovered.The establishment of cDNA library and the discovery of the new genes will lay a foundation for further studying the gene functions and screening the immunodiagnostic antigens.

Objective To investigate the clinical significance of fiberoptic ductoscopy-guided intraductal biopsy in diagnosing nipple discharge.Methods From May 2006 to April 2007,screening fiberoptic ductoscopy was performed for intraductal papillary lesions in 53 ducts among 51 patients.Fiberoptic ductoscopy-guided intraductal biopsy was carried out followed by open microdochectomy. Results Except for a failure in 5 ducts,biopsy found papilloma in 29 cases,ductal hyperplasia in 15 cases,severe ductal hyperplasia in 2 and carcinoma in 2.Microdochectomy revealed 43 benign diseases (12 solitary intraductal papillomas,12 multiple intraductal papillomas,and 25 ductal hyperplasia)and 4 malignancies (3 ductal carcinoma in situ,1 invasive ductal carcinoma).Surgeries performed for the 5 ducts failing a biopsy attempt revealed papilloma in one and adenosis in 4.Compared with conventional microdochectomy,fiberoptic ductoscopy-guided intraductal biopsy can significantly increase the detection rate of solitary papilloma(40.7% vs. 92.6%,P＜0.05).It might also underestimate multiple intraductal papilloma and breast cancer. Conclusion Fiberoptic ductoscopy-guided intraductal biopsy is microinvasive,safe,convenient with a high success rate,and could be as a routine procedure after intraductal lesion found by screening fiberoptic ductoscopy.

Objective To investigate the methods of rectifying the excessive width of fold line and conglutination of the upper eyelid following blepharoplasty. Methods The width of double eyelid was redesigned, ranging from 6 mm to 8 mm. Then the scar of upper eyelid was excised about 1 mm to 2 mm, and the orbital septum fat flap, orbicularis oculi flap, infraorbicularis oculi fat flap and injection of lipochondria were utilized to fill the depression of upper eyelid. Results In our series, there were 20 eyelids of 16 cases receiving rectification. Orbital septum fat flap was used to correct 2 eye-lids, orbicularis oculi flap 4 eyelids, infraorbicularis oculi fat flap 10 eyelids and injection of lipochon-dria 4 cases. Among 12 eases of following-up, 10 of them were satisfied with the postoperative effects. The results were acceptable in other 2 cases. Conclusion It is a good approach to correct the excessive width of fold line and conglutination of the upper eyelid with local flaps, including the orbital septum fat flap, orbicularis oculi flap, infraorbicularis oculi fat flap and injection of lipochondria.

To compare the neuroprotective and anti-dementia pharmacological effects of chiral oxiracetam, glutamate and calcium ions were used to establish neuronal injury models in vitro, and the protective effects of chiral oxiracetam on primary neurons were assayed by MTT. Permanent bilateral common carotid artery occlusion (2-VO)-induced rats were randomly divided into sham group, model group, galantamine 3 mg‧kg^-1 group, oxiracetam groups (30, 100 and 200 mg‧kg^-1), S-oxiracetam groups (30, 100 and 200 mg‧kg^-1) and R-oxiracetam 200 mg‧kg^-1 group. The animal experiments in the present study were performed in accordance with the Ethical Guidelines of the Laboratory Animal Welfare Ethical Committee of Peking Union Medical College. Morris water maze and step-down test were applied to evaluate the cognitive dysfunction induced by cerebral hypoperfusion in rats. Oxiracetam, S-oxiracetam and R-oxiracetam exerted protective effects on primary neuronal damage caused by various stimuli, and oxiracetam and S-oxiracetam showed better neuro-protective effects. Morris water maze and step-down results showed that oxiracetam, S-oxiracetam and R-oxiracetam improved the cognition of 2-VO rats. In summary, S-oxiracetam exerted a better neuro-protective effect than oxiracetam and R-oxiracetam.

A total of 60 ankylosing spondylitis patients scheduled for elective surgery with anticipated difficult airway were enrolled and randomly assigned into either dexmedetomidine (D) or midazolam plus sufentanil (MF) group.Group D:topical nasal anesthesia and a loading dose of dexmedetomidine at 1.0 μg/kg in 10 min; group MF:intravenous infusion of 0.05 mg/kg midazolam plus 3 μg/kg sufentanil.Fiberoptic bronchoscopic (FOB)-assisted awake nasotracheal intubation was performed.Mean arterial pressure (MAP),heart rate (HR),Pulse oxygen saturation (SpO2),Ramsay score and success rate of intubation were recorded and compared between two groups.The intubation conditions and level of comfort were also evaluated.MAP and HR of group D at FOB through postnaris (T1),peep the epiglottis(T2),intubation success immediately(T3)and 1 min after intubation(T4) were significantly lower (P ＜ 0.05 or P ＜ 0.01) than those of group MF while Ramsay sedation scores were obviously higher (P ＜ 0.05) than those of group MF.Group D with endotracheal intubation comfort level 5 score of grade 1-2 were 8 and 14 cases and were significantly higher than 4 and 10 cases of group MF.Immediately after intubation,level 3 scores in grade 1 of group D (n =21) were significantly higher than group MF (n =12) ; initial success rate of intubation in group D was obviously higher than that in group MF (70％,n =21 vs.47％,n =14).And the incidence of unpleasant intubation memory in group D was lower than that in group MF (37％,n =11 vs.67％,n =20).Fiberoptic bronchoscopic-assisted nasotracheal intubation offers better conditions for intubation and reduces the incidence rate of intraoperative awareness.

Objective:To study the influence of thrombus aspiration combined tirofiban on patients with acute ST seg-ment elevation myocardial infarction (STEMI)after primary percutaneous coronary intervention (PCI).Methods:A total of 98 patients,who received primary PCI because of STEMI in our hospital from Jan 2012 to Mar 2013,were selected.They were divided into thrombus aspiration group (n=48,received pure thrombus aspiration)and com-bined treatment group (n = 50,received thrombus aspiration combined intracoronary tirofiban injection during PCI).Coronary angiography (CAG)instantly after PCI and follow-up condition during hospitalization and six months after discharge were compared between two groups.Results:(1)Compared with thrombus aspiration group after PCI,there were significant rise in TIMI blood flow grade [(2.3±0.6)grades vs.(2.7±0.3)grades],per-centage of TIMI flow grade 3 (72.9% vs.90.0%)and ST segment regression >50% rate within 90min after PCI (52.1% vs.74.0%),P < 0.05 or < 0.01,and significant reduction in percentage of postoperative no-reflow (18.8% vs.4.0%,P =0.038)in combined treatment group in hospital;(2)After six-month follow-up,left ven-tricular ejection fraction (LVEF)of combined treatment group was significantly higher than that of thrombus aspi-ration group [(58±6.3)% vs.(51±5.6)%,P <0.05].Conclusion:Thrombus aspiration combined tirofiban can effectively reduce coronary thrombus burden and improve cardiac function in STEMI patients during primary PCI.
