Abundant experiences have already been accumulated in treatment of stroke with acupuncture. Development of rehabilitation theory also brings unprecedented opportunity and challenge to acupuncture. Combined with the modern rehabilitation theory and practice, it is very helpful to deepen the understanding on treatment of acupuncture for cerebral apoplexy and enhance the therapeutic effect in clinic by studying the mechanism of acupuncture treatment, opportunity of intervention, selection of acupoints, needling manipulations and quantity of stimulations etc. Through analysis on the necessity and the way of combination of acupuncture and modern rehabilitation, it is concluded that rehabilitation evaluation, rehabilitation phases and obstacle analysis should be taken as references by acupuncturists to reinforce the therapeutic effect and creditability of acupuncture treatment on cerebral apoplexy.

Objective:To prepare nanobody-based immunotoxin BI7D12-PE38KDEL targeting EGFR and to examine its cytotoxicity against EGFR positive tumor cells.Methods:By using molecular cloning strategy,prokaryotic expression construct of pET28a-BI7D12-PE38KDEL was generated which consisted of nanobody 7D12 targeting EGFR in the form of a divalent fused with PE38KDEL,a truncated form of pseudomonas exotoxin A via a flexible peptide(G4S)4,and then transformed into E.coli BL21(DE3).Protein expression was induced by adding IPTG,purified by Ni-affinity column chromatography,and verified by Western blot.The binding capacity of the resulted immunotoxin to EGFR-positive cells A549,HT29,MCF-7 and EGFR-negative cells CEM,Jurkat were determined by flow cytometry assay,and its cytotoxicity against the target cells was examined.Briefly,tumor cells were treated with different dosage of the immunotoxin,and the killing efficacy of BI7D12-PE38KDEL on these cells were assessed by WST-1 assay after 72 hours.Results:The SDS-PAGE and Western blot results showed the recombinant immunotoxin BI7D12-PE38KDEL was successfully prepared,and majority of them was expressed in soluble form.BI7D12-PE38KDEL could selectively bind to EGFR-positive cells of A549,HT29,and MCF-7.More importantly,the immunotoxin exhibited much more significant killing effect on these EGFR positive cells compared to the negative control group of CEM and Jurkat cells(P<0.01).Conclusion:In the current study,the nanobody-based immunotoxin BI7D12-PE38KDEL targeting EGFR was successfully prepared and exhibited a superior inhibition effect for the growth of EGFR-positive cells.

Objective To investigate the clinical effects of minimally invasive vitrectomy combined with cataract surgery for myopic foveoschisis in young and middle-aged. Methods Sixty myopic eyes with myopic fo-veoschisis diagnosed from September 2013 to October 2015 in our hospital were included in the study. According to different surgical methods ,patients were divided into two groups:combined operation group(vitrectomy combined with lens replacement surgery,30 eyes)and staged operation group(simple vitrectomy group,30 eyes). Cataract surgery were performed according to the opacity of lens. All the patients were followed up for 6~12 months. Reop-eration rate of staged operation group ,the best corrected visual acuity(BCVA),the distant and near visual acuity and retinal reattachment rate of each group were observed. Every patient was interviewed with a questionnaire about visual quality at 6th month after surgery. Results 27 eyes developed lens opacity after operation(90%)in staged operation group,among them,21 eyes underwent secondary cataract surgery(70%). The BCVA recovery,postop-erative distant vision,and preoperative and postoperative distant vision difference in the combined operation group were significantly higher than those in the staged group(P<0.05). There were no significant differences in macu-lar retinal condition and retinal reattachment rate between the two groups(P > 0.05). Six months after operation, the visual quality of the combined operation group was significantly better than that of the staged group(t=-3.95, P = 0.00). In the combined surgery group,the scores of distant vision,stereopsis and visual fatigue were higher than those of staged operation group. The score of dry eye and night glare in staged operation group was higher than that in combined operation group(all P<0.05). Conclusions Vitrectomy combined with intraocular lens replace-ment for myopic foveoschisis in young and middle-aged people can avoid second operations and improves the visual function,proving to be a feasible operation in clinic.

OBJECTIVETo evaluate clinical application and clinical outcomes of free flap pedicled with supracarpal cutaneous branch of ulnar artery in repairing of finger replantation with skin defect.

METHODSFrom April 2007 to March 2013,25 patients affected by finger amputation with skin defect were replanted and repaired by free flap pedicled with supracarpal cutaneous branch of ulnar artery. Among them, 18 patients were male and 7 were female,with an average age of 31.5 years old (ranged 16 to 58). The time of trauma to admission ranged from 45 to 210 min (averaged 105). Fifteen patients were complete separted, and 10 patients were non-complete separated. The area of flaps ranged from 3.5 cm x 2.0 cm to 4.5 cm x 3.0 cm, and the vessels were anastomosed through end-to-end. The functional evaluation standard of finger replantation was used to evaluate the postoperative function.

RESULTSTwenty-four cases were finally survived. Two flaps occurred vascular crisisin within 48 h after operation, one of which was survived after anti-vasospasm treatment and changing dressing,another was replanted finger for failed to survive. One had infection and healed after changing dressing. Twenty-four cases were followed up from 3 to 38 months with an average of 16.5 months. The appearance and texture of flaps were satisfactory, and the superficial senses of pain and touch were recovered,and two-point discrimination was 5.5 to 11 mm (averaged 7.4 mm). According to functional evaluation standard finger replantationissued by Hand Surgery Association of Chinese Medical Association, 8 cases got excellent results, 14 good and 2 poor.

CONCLUSIONThe free flap pedicled with supracarpal cutaneous branch of ulnar artery can be used in complex finger replantation with skin and vessels defect, which can extend operation indications, recover function and appearance for maximum.

OBJECTIVETo investigate and compare the clinical significance of (18)F-FDG single-photon emission computed tomography and computed tomography (SPECT-CT) in the diagnosis and staging of lung cancer.

METHODSFrom July 2005 to July 2007, 71 patients with suspected lung cancer received conventional CT and SPECT-CT examination. Fifty-seven of the 71 patients had definite pathological or cytological diagnosis, consisting of 52 malignant lung tumors and 5 benign pulmonary nodules. Forty-three patients underwent surgical resection with different modes. Thirty-seven of the 43 surgically treated patients had available complete data of CT, SPECT-CT and pathological results.

RESULTSTaking the pathological diagnosis as gold standard, the sensitivity, specificity and accuracy of diagnosing pulmonary lesions suspected as lung cancer were 84.6% (44/52), 80.0% (4/5), 84.2% (48/57) for conventional CT and 92.3% (48/52), 80.0% (4/5), 91.2% (52/57) for SPECT-CT, respectively. If taking the pathological TNM staging results as gold standard, the concordance rates of TNM staging with pathological TNM staging results was 59.5% (22/37) for CT and 67.6% (25/37) for SPECT-CT. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of staging hilar and mediastinal lymph nodes were 76.9%, 79.2%, 78.4%, 66.6%, 86.4% for conventional CT versus 61.5%, 75.0%, 70.3%, 57.1%, 78.3% for SPECT-CT (P > 0.05), respectively. There was no statistically significant difference between conventional CT and SPECT-CT in the accuracy of diagnosing and staging for the suspected pulmonary lesions (P > 0.05).

CONCLUSIONSPECT-CT is likely superior to conventional CT in the diagnosing and staging for lung cancer. It can be used as a non-invasive supplementary tool for differential diagnosis between malignant and benign pulmonary lesions and in diagnosis of lymph node > 1 cm in diameter.

BACKGROUNDDonor-pretreatment with ulinastatin may influence the liver graft during cold preservation. The aim of this research was to determine whether pretreatment of donor liver with Ulinastatin can attenuate cold preservation injury, and to explore the mechanism by which Ulinastatin affects the donor liver graft.

METHODSOne hundred and forty-four Wistar rats were divided into the Ulinastatin treatment group (T group) pretreated with Ulinastatin 50 000 U/kg and control group (C group) treated with 0.9% normal saline via peritoneal injection prior to the anesthetization. After the abdominal cavity was opened and perfused with cold Ringer's lactate solution, the liver was harvested. The harvested liver was preserved in cold Ringer's lactate solution for 0, 2, 6, 24 hours, at which time the liver tissue was sampled for determination of dry weight and wet weight, Na(+)-K(+)-ATPase and Ca(2+)-ATPase activity, lactic acid dehydrogenase (LDH) activity, lactic acid and malondialdehyde levels. Light microscopy and electron microscopy were used to observe liver morphology. The liver cold-preservation solution was taken for measurement of aspartate aminotransferase (AST) and alanine transaminase (ALT) levels. Correlation between ATPase activity and lactic acid level was analyzed by SPSS 13.0 for Windows.

RESULTSThe morphology in the T group had improved cell boundaries vs. the C group at each time point. Dry weight to wet weight in the T group was lower than in the C group at 6 hours (P < 0.05), but the difference was not significant at 24 hours. ALT levels in the T group were lower than that in the C group at 6 hours (P < 0.05) and 24 hours (P < 0.01). AST levels in the T group were lower than those in the C group at 2 hours (P < 0.05), 6 hours (P < 0.01) and 24 hours (P < 0.01). Na(+)-K(+)-ATPase activity in the T group was higher than in the C group and the mean difference between two groups was significant at 0 hour (P < 0.05) and 2 hours (P < 0.05). Ca(2+)-ATPase activity in the T group was higher than in the C group with the mean difference between two groups significant at 2 hours (P < 0.05). The T group had increased lactic acid levels at 0 hour (P < 0.01) and 2 hours (P < 0.05) compared with the C group, but there was no influence on the LDH activity at the same time. There were no obvious differences in the levels of malondialdehyde between the two groups at any time point. A linear correlation between Na(+)-K(+)-ATPase activity and lactic acid levels (r = 0.295, P < 0.05) was found.

CONCLUSIONSDonor-pretreatment with ulinastatin may protect the cells in a liver graft from ischemia injury during cold preservation; the mechanism may be due to its promotion for cell glycolysis and its preservation of ATPase activity.

OBJECTIVETo investigate the pharmacokinetic and distribution character of scutellarin in plasma and tissues in rats, in order to provide some references for rational drug use in the clinic.

METHODThe solution of scutellarin was administered to rats (80 mg x kg(-1)) by oral gavage. A high performance liquid chromatography method determinated the scutellarin concentration in rat plasma and tissue. The plasma samples were performed by solid phase extraction method. The other biological samples were extracted by ethyl acetate.

RESULTThe range of scutellarin in plasma and tissue in rats were 10-1280 ng x mL(-1) (R2 > 0.99), 40-1280 ng x g(-1) (R2 > 0.99), respectively. The lowest detection of scutellarin were 10 ng x mL(-1) and 40 ng x g(-1), the precision were less than 8%. The main pharmacokinetic parameters of scutellarin were as follows: tmax, Cmax, AUC and MRT being (7.7 +/- 0.9) h, (288.0 +/- 75.2) microg x L(-1), (5.6 +/- 1.6) microg x mL(-1) x h(-1), (17.5 +/- 1.4) h(-1), respectively.

CONCLUSIONThese methods applied the study of pharmacokinetics of scutellarin. After oral the scutellarin in rats, the concentration-time course doesn't obey any compartment model. The concentration-time curve is the double peaks.

OBJECTIVETo investigate the possibility to enhance the proliferation of adipose-derived stem cells (ASCs) in a delayed fat flap in rabbits.

METHODSA delayed fat flap was formed in one side of inguinal region of a rabbit. 21 days after operation, the fat tissues at the delayed flaps and at the unoperated side were harvested and digested with 0.25% collagenase and sieved. The cell suspensions were centrifuged. The cells were obtained from tissue precipitate after centrifugation. The expression rates of the surface marker (CD29, CD44, CD14 and CD45) were measured by FCM and compared between the experimental and control groups.

RESULTSExpression rates of CD29 and CD44 were higher in the delayed fat flap (74.06% and 90.74%) than in the contralateral fat tissue (62.88% and 77.54%, P < 0.05), while those of CD14 and CD45 were lower in the delayed fat flap (57.66% and 4.84%) than in the contralateral fat tissue (72.10% and 75.82%, P < 0.05 and P < 0.01).

CONCLUSIONSTissue hypoxic ischemia such as fat tissue in a delayed fat flap can promote proliferation of ASCs. It indicates that tissue in the delayed flap may be transplanted with better survival rate. The ischemia pretreatment of fat tissue may become a new method for fat transplantation.
