OBJECTIVETo investigate the effects of RCCS on cell seeding onto 3-D scaffold and cell-scaffold composite culture in vitro.

METHODSRabbit skin fibroblasts of passage 2 were seeded at 2 x 10(6) cell per cm(3) onto/into polyglycolic acid (PGA) foams by static seeding (dropping a cell suspension onto foams) or dynamic seeding (rotating PGA foams and a cell suspension in RCCS). Attachment of cells in foams was observed by cell-counting after trypsin digestion. The effects of culture condition were next studied by culturing cell-PGA complexes in RCCS versus static culture condition. Distribution and proliferation of cells in foams were investigated with MTT, stereomicroscope and scan electron microscope.

RESULTSNumbers of cells adhering to polymers increased gradually during an initial period of 24 hours. Eight, 12 and 24 hours after seeding, the rates of adhering cells were significantly higher in the dynamic seeding group than in the static seeding group (46.70% + 2.16% vs. 31.50% +/- 3.54%; 56.36% +/- 3.18% vs. 34.28% +/- 3.16%; 66.32% +/- 4.60% vs. 37.38% +/- 4.66%; P < 0.01). The dynamic culture method as compared to the static method resulted in new tissues with a higher cellularity and more uniform cell distribution during a 3 period of weeks.

CONCLUSIONSRCCS has advantages of promoting cell attachment, uniform migration and proliferation in polymer scaffolds and can be used for construction of 3-D cell-polymer tissues in vitro.

OBJECTIVETo observe the fetus protection effects of Zhixue Baotai Decoction (ZBD) on women of early threatened abortion with dark area surrounding pregnancy sac.

METHODSThe 105 patients with early threatened abortion, in whom vaginal bleeding was shown already, were randomly assigned to the treatment group and the control group, who were treated respectively with ZBD and progesterone to protect fetus. The efficacy of treatment was evaluated by dynamic monitoring of serum hormone and B-ultrasonic examination.

RESULTSAmong the 54 cases in the treatment group the fetus was protected successfully, showing a fetus protecting rate of 81.5%; while among the 51 cases in the control group, the protection was effective in 22 cases (43.1%), the success rate in the former was better (P<0.01). The dark area was absorbed in 16 out of 19 cases (84.2%) in the treatment group, while in the control group absorption occurred only in 6 out of 17 (35.3%).

CONCLUSIONThe effect of ZBD is superior to that of progesterone in treating women of early threatened abortion with dark area surrounding pregnancy sac.

Objective To carry out integrative development to available field battle portable X -ray machine,solving functional defect in quondam tripod and inconvenience in transport. Methods We used anthrop -machine engineering,electricity engineering and machinery engineering to undertake integrative design on whole machine. Results The whole machine can be quickly extended and folded in 2 minutes. Centric position of the sucker is 170 cm over the ground,and 45 cm away from column stand when the whole machine working. The machine can work in multi-angle and omnibearing. The whole machine can deposit in an appropriative crate with efficiency of anti-shock and seepage water when folding. Conclusion Integrative design of field battle portable X-ray machine increases projection range,boosts projection effect,strengthens medical service safeguard ability of radio-staff consumedly.

Objective To explore the role of CD 30 on CD4 + T lymphocyte and T lymphocyte subset activation in asthma pathogenesis.Methods Twenty seven asthma active attack patients,16 acute upper respiratory infection patients and 19 control children were randomly selected. Direct immunofluorescence flow cytometry was used to detect the CD 30 positive percentage on CD4 +cell; ELISA was used to detect the levels of interleukin(IL) 4 and IL 13 in culture supernatants of peripheral blood mononuclear cells(PBMC) and plasma total immunoglobulin E(IgE) level.Results Compared with control group and acute upper respiratory infection group, in asthmatic children the CD4 +CD 30 + percentage on CD4 + cell was elevated significantly; 2.The levels of IL 4 and IL 13 in supernatants of cultured lymphocyte were increased significantly, the plasma total IgE level was increased significantly;3.There was a significant positive correlation of CD4 +CD 30 + cell percentage with the levels of IL 4 and IL 13 in culture supernatants and plasma total IgE.Conclusions The cell that could produce Th2 derived cytokine may consist of CD 30 +cell;When CD 30 L combined with CD 30 on CD4 + cells ,it might result in Th2 cell proliferation ,develop and release Th2 derived cytokine; IL 4 and IL 13 could induce B cell production and secrete more IgE. It is suggested that CD 30 and imbalance of Th2 subset may play an important role in asthma pathogenesis.

Objective:To compare two flexible embryo catheters and determine whether clinical out-come differs in the in vitro fertilization-embryo transfer (IVF-ET)cycles.Methods:This prospective control study was conducted by one doctor between July 2012 and November 2013.In the study,2 064 patients undergoing fresh embryo transfer by using IVF-ET/intracytoplasmic sperm injection (ICSI)-ET in Reproductive Medical Center of Peking University Third Hospital were recruited.The subjects were di-vided into two groups.Cook Sydney IVF embryo transfer catheters (product model:K-JETS-7019-SIVF) were used for embryo transfer in group 1 (n =949),and FrydmanCCD catheters (product model:131230301)were used in group 2 (n =1 115).Pregnancy outcomes were compared between these two groups.Results:There was no significant difference in age,diagnosis for infertility and stimulation proto-col used between the two groups.In addition,there was no difference in the number of oocytes collected and in the number and score of embryos transferred.The significantly higher implantation rate,clinical pregnancy rate,and live birth rate (34.40% vs.26.92%,51.21% vs.41.52%,42.57% vs. 33.09%,P <0.05)were observed in group 1 compared with group 2.The abortion rate was not signifi-cantly different between the two groups (11.93% vs.15.98%,P >0.05).The proportion of difficult transfer was higher in group 1 than that in group 2 (5.27% vs.3.41%,P <0.05 ).There was no difference in the clinical pregnancy rate and live birth rate between the two difficult transfer cycles.Con-clusion:The type of embryo transfer catheter affects the clinical outcome in IVF.Good clinical outcome can be obtained by using Cook Sydney IVF catheter,which is worthy of clinical promotion.

To obtain high-yield avilamycin-producing strains,low energy N~+ ion implantation technology and screening of streptomycin-re- sistant mutants are used in the study on breeding mutation.The results show that,“saddle”region,which range is from 3?10~(15) to 5?10~(15) ions/cm~2,has got better induced mutation action.It also means that the strain's resistant mutation and yield mutation closely correlate to each other,and the method of streptomycin resistant screening is feasible.We have isolated a high-yield strain SVT-45 which the productivi- ty is 195% higher than the original strain's in the rotation-flask experiments.These results showed that the ion implantation was an effective method for microbe mutagensis.

OBJECTIVETo study 3 different strategies of urine drainage following hypospadias urethroplasty, the clinical nursing in their application, and their effects.

METHODSWe retrospectively analyzed the clinical data of 595 cases of hypospadias treated by urethroplasty. After surgery, 133 of the patients underwent urine drainage by suprapubic cystostomy (group A), 202 by urethral stent- tube indwelling (group B), and 260 by early initiative micturition with the urethral stent-tube (group C). All the patients received routine postoperative nursing care required for hypospadias repair.

RESULTSOperations were successfully completed in all the cases. Group C showed a remarkably shorter hospital stay and lower incidence rates of urinary fistula and urethral stricture than groups A and B (P<0.05), but there were no significant differences in the three indexes between A and B (P<0.05).

CONCLUSIONFor urine drainage following hypospadias repair, early initiative micturition with the urethral stent-tube can significantly reduce postoperative complications, decrease difficulties and workload of nursing care, and shorten the hospital stay of the patient.
