Recently the combination of acupuncture with assisted reproductive technology (ART) to increase the outcomes of ART is being widely studied. In this article, the literatures concerning random controlled clinical trials since 2002 are reviewed and the designs of the trials, especially the timing of acupuncture, are evaluated. Over the past 5 years, the related clinical trials have primarily showed that acupuncture done immediately before and after embryo transfer might increase the assisted reproduction rates, but still requiring further high quality trials with large samples; in addition, different stimulation modes could produce different result, and so far there has not been a consensus as to the optimal time-point for the acupuncture intervention during the in vitro fertilization-embryo transfer (IVF-ET) course. Since the effects of acupuncture change with women's endocrine cycles, it is important and possible to make a breakthrough in ART outcomes if acupuncture is performed at a suitable time point during the cycle of IVF/ET combined with ART.

Objective To investigate the clinical effect and safety of three dimensional conformal radiotherapy (3D-CRT)for patients with cervical cancer after radical operation in stage ⅠA to ⅡA.Methods The data of 119 patients of cervical cancer in ⅠA-ⅡA with postoperative radiotherapy in our hospital were analyzed retrospectively.Of which 56 patients were treated with 3D-CRT radiotherapy (3D-CRT group),63 patients were treated with conventional radiotherapy (conventional group).The differences radiation reactions and quality of life between two groups were compared.Results The local control rate of 3D-CRT group in the first 12 and 18 months after surgery were 87.50% and 82.14%,respectively,which were significantly higher than those of conventional group(71.43%,65.08%),the difference was statistical significance(P <0.05).The survival rate of 3D-CRT group after 1 year,2 years,3 years were respectively 91.07%,83.93%, 71.43%,compared with the conventional group (84.13%,73.02%,65.08%),the difference was not statistically significant (P >0.05). Patients of 3D-CRT group were followed up for 3 years,the median survival time was 34.29 months,which was longer than the 31.08-month of conventional group,the difference was statistically significant(χ2 =4.116,P =0.042).Quality of life of 3D-CRT group (60.81 ±4.28) point was lower than that of conventional group (63.75 ±5.03)point,and the difference was statistically significant(P <0.05).The rate of early radiation reaction(rectal reaction,vaginitis)and late radiation reaction (mild or moderate radiation proctitis)in 3D-CRT group were lower than those in the conventional group,the difference was statistically significant(P <0.05 ).Conclusion The 3D-CRT has effect on the long-term prognosis of patients with cervical cancer in stage ⅠA-ⅡA,which can significantly reduce the radiation reaction and improve the quality of life of patients.

BACKGROUND: Dihydrolycorine (DL) can inhibit the peripheral release of catecholamine from sympathetic nerve ending and block α, β adrenalinergic receptor. It has multiple pharmacological actions, such as vascular dilation, hypotension, anti-hypoglycemia and anti-ischemia.OBJECTIVE: To investigate the selective effect of DL on basilar artery,thoracic aorta and ventricular papillary muscle of rabbit by means of observing the vasoconstriction induced by noradrenaline bitartrate and KCl.DESIGN: Observation of comparative experiment.SETTING: Pharmacological Department of Yunyang Medical College.MATERIALS: This study was carried out at Pharmacological Department of Yunyang Medical College between March and July 2001, and 46 adult healthy New Zealand rabbits were selected.METHODS: New Zealand rabbits were put to death by intravenous injection of 10 mL air from the vein of aural edge, and soon after death, brain,thoracic aorta and heart were obtained. Basilar artery and thoracic aorta was linked into 4.0-5.0 mm vascular rings; meanwhile, ventricular papillary muscle were separated and connected with tension transducer. Obserdose of noradrenaline bitartrate or KCl: Sub-maximal constriction of thoracic aorta was induced by 0.1 mmol/L noradrenaline bitartrate or W60 mmol/L KCl, and when constriction curve became stable, DL or nimodipine of different dosage was added. Basilar artery was exposed to 0.1 mmol/L noradrenaline bitartrate or 60 mol/L KCl, and rinsing fluid was changed once every 20 minutes and thrice in all when vasocontratcion reached the peak level, then different dosage of DL or nimodipine was added 20 minutes later, and the changes of vasoconstriction curve due to administration of single dose of noradrenaline bitartrate or KCl were obconstriction of ventricular papillary muscular induced by electro-stimulation: Electro-stimulation was used to stimulate the ventricle papillary muscular synchronized constriction with the frequency of once per second,wavelength of 3 ms and threshold voltage of 120%; when constriction curve became stable, DL or nimodipine was administered in a accumulative way.ence of DL or nimodipine on the half-effective concentration of noradrenaline bitartrate or KCl that contributed to the vascular ring constriction of rabbit.RESULTS: Basilar artery, thoracic aorta and ventricular papillary muscle Resting tension of basilar artery was increased by DL but decreased by niof basilar artery and thoracic aorta induced by noradrenaline bitartrate and KCl can be relaxed by DL in a dose dependant manner, and the half-effective concentration was (6.69±3.12)×10-4, (3.41±1.52)×10-3mmol/L for basilar artery, and (1.49±0.59)×10-3, (2.91±0.99)×10-3 mmol/L for thoracic aorta, displaying stronger inhibition on the constriction of basilar artery induced by noradrenaline bitartrate than on the contraction induced by KCl.On the contrary, nimodipine showed stronger depression on KCl-induced constriction than on the constriction induced by noradrenaline bitartrate.ventricle papillary muscular induced by electro-stimulation in a dose-dependant manner, and the half-effective concentration of DL on the contraction of ventricle papillary muscle induced by electro-stimulation was significantly higher than that induced by noradrenaline bitartrate.CONCLUSION: DL displays obvious selective effect on basilar artery of rabbit, the possible existence of constrictive α1 receptor subtype and dilating β receptor on basilar artery might be correlated with the selective function of DL, which benefit, for the improvement of blood supply in the ischemic region.

Objectives To investigate the clinical significance of the airway inflammation mediators,eosinophil cationic protein (ECP) and urinary leukotriene E4 (LTE4),in children with respiratory syncytial virus (RSV) bronchiolitis. Methods A total of 120 inpatients with RSV bronchiolitis were classified into atopic and non-atopic groups. And 30 healthy subjects were se-lected as normal controls. Urinary LTE4 was determined by ELISA and ECP concentration in nasopharyngeal secretions (NPS) was tested by UniCAP100 allergen detector. The differences among groups were compared. Results The urinary LTE4 level in atopic group (172.21 ± 67.29 pg/ml) was elevated significantly (P<0.01) than that of non-atopic group (78.21 ± 28.78 pg/ml) and control group (44.22±16.14pg/ml). Significance was also found between non-atopic and control groups (P<0.01). Statistical anal-ysis indicated that urinary LTE4 positively correlated to serum IgE and ECP in children with RSV bronchiolitis (r=0.57,0.49;P<0.01). Conclusions The level of urinary LTE4 and ECP in NPS can provide the reference for treatment and prognosis of children with RSV bronchiolitis.

Objective To compare clinical outcome of intracytoplasmic sperm injection(ICSI)cycle by using fresh and cryopreserved-thawed testicular and epididymal spermatozoa in azoospermic patients.Methods Between September 2006 and May 2007,208 azoospermic patients underwent in vitro fertilization(IVF)were treated in Center of Reproductive Medicine,Peking University Third Hospital.Those couples were divided into two groups based on their wishes,including 171 cases in fresh group and 37 cases in cryopreserved-thawed group.The cryopreserved testicular or epididymal spermatozoa were thawed and recovered before ICSI procedure iu thawed group.The outcomes of ICSI in each group were compared.including clinical outcomes(two pronuclear fertilization,high quality embryo,clinical pregnancy and embryo implantation)and pregnancy outcomes(spontaneous miscarriage,gestational weeks and neonatal birth weight).Results (1),The utilization rate were 92%(23/25)in cryopreserved-thawed testicular spermatozoa and 100%(12/12)in epididymal spermatozoa.(2)Between fresh and cryopreserved-thawed groups,no statistical difference was observed in two pronuclear fertilization rate[62.25%(973/1563)vs.64.53%(282/437),P=0.960],high quality embryo rate[78.9%(768/973)vs.79.1%(223/282),P=0.985],clinical pregnancy rate per embryo transfer[44.4%(60/135)vs.46.9%(15/32),P:0.688]and embryo implantation rate[29.3%(84/287)vs.33.3%(23/69),P=0.508].(3)No significant difference between flesh and cryopreserved group was found in spontaneous miscarriage rate (11%vs.7%,P＝1.000),gestational weeks(single birth:39.0 weeks vs.38.7 weeks,P:0.538;twins:36.8 weeks vs.36.3 weeks,P=0.571)and birth weight(single birth:3409 g vs.3350 g,P=0.699;twins:2584 g vs.2635 g,P=0.703).Conclusion It suggested that tissue from the azoospermic patients who underwent diagnostic testieular and epididymal biopsy should be eryopreseved for IVF-ET.
