To introduce the international registration condition of acupuncture clinical research. With the examples of World Health Organization International Clinical Trials Registry Platform and the U. S. National Institutes of Health Clinical Registration Platform, the registration method and current condition of acupuncture clinical trials in international clinical trials registration platform were analyzed. The results indicate that the number of acupuncture clinical trials registration is gradually increased and the registration number from China is on the rise as well. But most domestic acupuncture clinical researches haven't been registered arid the researchers' valuing degree for clinical trials registration and methodology research needs to be improved.

Objective To evaluate the perfectibility of colposcopy directed biopsy for the diagnosis of cervical intraepithelial(CIN)through cervial conization by loop electrosurgical excision procedure(LEEP).Methods Biopsy by colposcopy and biopsy after LEEP were analyzed retrospectively in 108 cases of cervical intraepithelial neoplasia to study the related factors of affecting the coincidence rate.Results Comparison of pathological hanges following both LEEP and colposcopy showed that 69 cases were the same,24 upgrade,and 15 downgrade.Conclusion LEEP is a kind of effective and perfect method for the specific diagnosis and treatment of CIN.Colposcopically directed biopsy has its limitations.

Background Scarring of the filtering bleb is a main cause of filtering surgical failure in glaucoma.It has been reposed that tetrandrine could suppress the proliferation of cultured human fibroblast of Tenons capsule in vitro and thus has the potential effect to prevent scarring after the filtering surgery. Objective Present study was to investigate the anti-cicatricial effect of tetrandrine drug delivery system(Tet DDS)during filtration surgery. Methods Filtration surgery was performed in bilateral eyes of 18 New Zealand white rabbits.The Tet DDS with 0.3 mg Tet,0.2 mg Tet or free-Tet were implanted subcunjunctially during the surgery.The filtering blebs were scored in 1 day,4,7,10,14 days after referring to the corneal thickness and bleb range under the slit-lamp biomicroscopy.The morphology of filtering bleb was assessed by in vivo confocal microscopy in 7 and 14 days after operation.The filtering bleb specimen was prepared in 7 and 14 days for the histopathological examination. Results The filtering bleb scores in Tet DDS implantation groups were significantly higher than those in free-Tet DDS group from 4 days through 14 days after trabeculectomy(P＜0.01),and the scores showed a considerably increase in 0.3 mg Tet DDS group compared with 0.2 mg Tet DDS group from 7 days through 14 days after trabeculectomy(P＜0.05).The filtering blebs of Tet DDS implantation groups were found with distinct subepithelial cystic spaces under the light microscopy and in vivo confocal microscopy on the 7th day and 14th day after surgery.Compared with free-Tet DDS group,the numbers of subepithelial mierocysts were much more(P＜0.01)and the area of microcysts was larger(P＜0.01)in Tet DDS group.The filtering tissue presented with more subepithelial microcysts and larger microcysts range in 0.3 mg Tet DDS group than 0.2 mg Tet DDS group in 7 and 14 days after operation(P＜0.05).The inflammatory cell infiltration wag milder in 0.3 mg Tet DDS group in comparison with 0.2 mg Tet DDS group and free-Ted DDS group.Conclusion Tet DDS has strong inhibitory effects on inflammatory cells activity and fibroblagt activity the early stage after filtering surgery and therefore improve the surgery success rate.

Objective To review the clinical experience of diagnosis and treatment of the congenital diaphragmatic hernia in newborn infants. Methods Thirty-three neonates were diagnosed having congenital diaphragmatic hernia in our hospital from Jan. 1,2004 to Sept. 30, 2009. The clinical data was retrospectively reviewed. Results 21 cases were treated surgically and 17 survived, while 4 cases died. The main cause of death was congenital pulmonary dysplasia. Another 12 cases refused to accept surgical treatment and they all died, one died shortly after he was born. Four cases who had been diagnosed by prenatal ultrasonography were survived. Conclusion The mortality of congenital diaphragmatic hernia in neonates was still high. Prenatal diagnosis of the congenital diaphragmatic hernia is very important and the cooperation between the obstetrics, neonatology and cardiothoracic surgery will improve the survival rate of congenital diaphragmatic hernia in newborn infants.

A strain producing eggshell membrane protease (ESM protease) was isolated from the soil and identified as Pseudomonas aeruginosa. The enzyme isolated from the fermentation liquid of this strain and purified by ammonium sulfate precipitation, quadratic anion-exchange chromatography exhibited eggshell membrane degrading activity of 304.5 U/mg. By SDS-PAGE, the protein molecular mass is 32 kD. The N-terminal amino acid sequence of this protease is: Ala, Glu, Ala, Gly, Gly, Val, Ala, Gly, Lys, Glu, Asp, Ala, Ala, Glu, Leu.

Objective:To explore and compare the perfusion pattern of oral mucosa on Han Chinese and Caucasian by laser-doppler flowmetry.Methods:A cross-sectional study was carried out,in 20 healthy Han Chinese adult subjects (average age:28.4 years)and 20 healthy Caucasian (average age:25.3 years)adult subjects,either gender with 10 subjects.Gingival perfusion was evaluated at 8 points (including upper incisor labial gingival,lower incisor labial gingival,palatal mucosa,cheek mucosa) using a laser-doppler flowmetry(O2C,Medizintechnik GmbH,Germany).Each measurement was car-ried out 25 seconds consisting 5 seconds of foreperiod and 20 seconds of work period,without pressure. The measurements were taken by two well-trained doctors,each measurement was exammed 3 times by an examiner,and the average value was recorded as final data.Each measurement has 4 parame ters:SpO2 (oxygen saturation),rHB (relative amount of hemoglobin),flow (the blood flow of unit interval),and velocity (blood flow velocity).We compared the data by different sites,different genders,and different races.Results:For palatal gingival,the average SpO2 was 77.1% ±10.9%,the average rHB 67.8 ± 11.1,and the average flow 194.1 ±63.7,which presented significant lower values than other oral muco-sa.There was no significant difference among other sites.There was some significant difference between the Caucasian and the Han Chinese:the maxillary central incisor oxygen saturation (SpO2)which were averages of 75.6% ±8.2% and 70.4% ±7.6%;buccal mucosa hemoglobin (rHB)averages of 79.9 ±5.8 and 83.5 ±6.6,which had statistical differences.For most measurement points,the oxygen saturation on men was lower than that on women,which had significant difference.Conclusion:To inves-tigate microcirculation pattern,oral mucosa can be the good observation site.Laser-doppler flowmetry is a well-documented instrument to survey on microcirculation.There may be differences between the genders in hemoglobin oxygen-binding capacity,which may have some impact on the ability of soft tissue healing. Oral mucosa display more blood perfusion than attached gingival.As the recipient site of gingival graft, maxilla and mandible have slight difference in blood supply.

Objective To ob se rve the effects of danazol on hypothalamus-pituitary-gonad axises and expressi ons of hypothalamic GnRH and pituitary GnRH receptor mRNA in female rats. Methods Female rats at 5 days of age were given a sin gle subcutaneous injection of 300 ?g danazol to induce true precocious puberty. Animals were divided into 3 groups: normal control, model group and vehicle gro up. The day of vaginal opening from 25 days of age was monitored, and the establ ishment of first estrus cycle from the day of vaginal opening was investigated b y examination of vaginal smears. The weights of body, pituitary, adrenal, uterus and ovary were measured to identify the developmental status of main organs. Th e expressions of hypothalamic GnRH and pituitary GnRH receptor mRNA were assayed by semi-quantitative RT-PCR. Results Female rats treated with danazol significantly (P

Objective:To provide some experimental basis of cell biomechanics for clinic treatment of massage by exploring synthesis and liberation of NO and IL-1? from fascia tissue cells of rat under pressure stimulation in vitro.Methods:Fascia tissue cells of rat were cultured in vitro.After morphological identi cation,50kPa pressure was forced on these cells,then the contents of NO and IL-1? in culture medium were detected.Results:The fascia tissue cells are mainly made up of broblast cells.The contents of NO and IL-1? in culture medium were both increased signi cantly under pressure stress.Conclusion:Fascia tissue cells can receive the mechanical stimulation,and transform the mechanical signals into biological signals.The reaction to mechanical stimulation may be one of the cell biomechanical principles of massage.
