To observed the Clinical effect of ropivacaine (Rop) of different concentration used for analgesia of labor, and ex plore the ideal concentration and dosage. Methods: 45 case s of ASA Ⅰ-Ⅱ primiparae nearing labor were vandomly divided three groups rand omly (0.16% Rop group, 0.2% Rop group were assigned 15 cases). The analgesia, in which the cervical os had opened up to 2-3cm; the controlled group was not giv en the analgesia of labor. BP, SpO2, EKG, PETCO2, cerrical contraction , fetal cardiac sounds were monitored continuously in the perinatal analgesia pe riod. The analgesia effects were determined by giving a mark for pain by VAPS, motor nerve blockings were given amark by Bromage scale; Apgar scale were conduc ted 1-5 min after neonates were labored out. Results: The vital signs of three groups were stable in perinatal; the VAPS scale was lower s ignificantly in observed group than in controlled group; while the blocking freq uency and extent of motor nerve were highest from 0.2% Rop, which had light inhi bitory effect to cervical contraction, causing the dosage of oxytocin to increas e relatively; the NACS scale 24 h after labor was more increased significantly in observed group than controlled group. Conclusion: The un ique blockings to sense and motor were obviously separate, having no obvious eff ect to blood stream of uterus and placenta, being benificial to analgesia in per inatal. The 0.16% Rop was a more ideal local anaesthesia agent than 0.2% Rop .

Objective To study a improved technique by releasing the orbicularis retaining ligament in orbicularis oculi muscle supension blepharoplasty. Release of the orbicularis retaining ligament could cut off the contact between orbitomalar skin and periosteum at inferior orbital rim, and carry the point of tightening orbitomalar skin in orbicularis oculi muscle supension blepharoplasty. Methods There were 409 patients with apparent orbitmalar fold. The methods of releasing orbicularis retaining ligament and orbital septum fixation were added to improve the orbicularis oculi muscle supension blepharoplasty. Results 409 cases were treated using this method over the past 3 years. All results were satisfactory. No complications were observed. Conclusion This improved method of orbicularis oculi muscle supension blepharoplasty is useful for orbitomalar skin rolling, especially for orbitmalar fold. The release allows effective redraping and upward mobilization of the orbicularis of the lower lid and the premalar soft tissues. This method is a simple, safe and effective procedure for the correction of tear trough deformity and well-demarcated lid/cheek junction in lower eyelid belpharoplasty. It is one of the best choices for lower eyelid blepharoplasty.

Data is the basis and soul of clinical trials. To obtain accurate data, strict and standard data management is essential, which can be effectively supported by quality control in statistical analysis. In this paper, we briefly introduce the concept of the quality control in clinical trials, and describe its contents and methods. We hope that this work will be helpful to the application of statistical quality control in data management of clinical trials.

AIM:To introduce the concept of bridging study and its strategies in clinical trials for new drug application.METHODS:The concept of bridging study proposed in the ICH E5 guideline was introduced,with a case using bridging strategies in the new drug applications(NDAs)approved by the regulatory authority in Japan.The concrete mode and the development of bridging studies in Asia were summarized.RESULTS:With the application of the ICH E5,some countries and regions have successfully used the bridging strategy in the new drug applications.The bridging strategy is becoming a common and practical basis for the decision making of marketing approvals of new drugs in the Asia-pacific country.CONCLUSION:The currently bridging studies in Asia will play an important role in the extrapolation of foreign clinical data in new drug application.Using bridging study is very helpful in judging ethnic differences of drugs,reducing duplication of clinical trails,as well as shortening clinical development periods.

Objective:To study the distribution pattern of CIK cells re-infused by different manner.Methods:Isotope 32P-? dATP and fluorescence dye CM-DiI were used individually to label CIK cells. CIK cells labeled by the two methods in vitro were inoculated to nude mice by intraperitoneal injection or tail vein injection. Radioactivity quantitative measurement and fluorescence microscopy were used to analysis dynamic distribution of CIK cells among organs of mice.Results:The CIK cells were quickly distributed to organs such as liver, spleen, kidney, lung, stomach and intestine after inoculation into nude mice. Among those organs, the liver, spleen and kidney showed highest distribution concentration of CIK cells. Early stage after infusion, concentration of CIK cells in lung above all reached peak via tail vein, and by means of intraperitoneal injection, distribution of CIK cells in intraperitoneal organs firstly got to max. CIK cells remained alive in liver and spleen for more than 2 weeks.Conclusion:The extensive distribution pattern of CIK cells among organs shows that CIK cells can be used as drugs against various malignant tumors in organism. Infusion of CIK cells via blood vessel maybe suit for tumor of organs with rich blood supply, and application by means of body-cavity way should suit for malignant effusions and limited lesion in it.

Objective To investigate the techniques and influence factors for the respiratory navigator echo triggered whole-heart coronary MR angiography(WH-CMRA)and evaluate its application in visualizing coronary arteries and the image quality.Methods Ninety two volunteers were acquired with WH-CMRA at 3 T MR scanner using respiratory navigator-echo gated TFE sequence.Imaging quality was visually graded as 0—Ⅳ grade according to the visual inspection,average length,diameter and sharpness of coronary arteries.The correlation between the imaging quality and respiratory pattern,heart rate and navigator efficiency was analyzed.Results The imaging quality in 92 cases was that 28 were graded as Ⅳ, 53 were graded as Ⅲ,9 were graded as Ⅱ and 2 were graded as Ⅰ.The successful rate of scan was 88% (81/92).The imaging quality is mainly graded as Ⅳ when the heart rate was less than 75 beats per minute (bpm)and the sharpness of vessel was(48?11)%.When heart rate was more than 75 bpm,the image quality was mostly graded as Ⅲ and the sharpness was(33?15)%.The correlation between heart rate and imaging quality score was negative(r=-0.726,P0.05).Conclusion 3 T WH-CMRA technique could facilitated the visualization of whole coronary arteries at free breathing but having indications on heart rate.

To study the B cell linear epitopes of rabies virus CVS-11 nucleoprotein, peptides were synthesized according to the amino acid sequences of B cell linear epitopes. Linear epitopes predicted by bioinformatics analysis were evaluated with immunological techniques. Indirect enzyme-linked immunosorbent assay showed that titers of antibodies to peptides (355-369 and 385-400 residues of rabies virus CVS-11 nucleoprotein) were above 1:12 800 in mouse sera. The antibodies recognized denatured rabies virus CVS-11 nucleoprotein in Western blot analysis. Purified anti-peptide antibodies recognized natural rabies virus CVS-11 nucleoprotein in BHK-21 cells in indirect fluorescent antibody test. The 355-369 and 385-400 residues of rabies virus CVS-11 nucleoprotein were validated as B cell linear epitopes.

OBJECTIVETo investigate the surgical techniques and therapeutic effect of eyelid divided nevus.

METHODSFrom January 2000 to January 2014, 27 cases with 27 eyelid divided nevi were treated by staged excision (2 cases), or full-thickness skin graft (20 cases) or frontal and facial expanded flaps (3 cases), or combined expanded flaps with skin grafts (2 cases) for large lesions. One case with skin graft underwent secondary treatment with expanded flap due to obvious scar.

RESULTSExcept for one case with residue lesion (0. 5 cm x 0. 5 cm), all the other cases underwent successful treatment with primary healing. All the patients were followed up for 3-48 months (average, 7. 4 months). Except for one case with secondary expanded flap treatment, all the other patients were satisfied with aesthetic and functional results. No occurrence happened.

CONCLUSIONSStaged excision and full-thickness skin grafts are simple and effective method for eyelid divided nevus. For large lesions, expanded flap, or combined with skin graft should be considered.
