Objective To explore the effect of analgesia management on the analgesic effect and the quality of delivery of labor analgesia. Methods The 80 cases were divided into two groups according to the odd number of labor analgesia, the control group without anesthesia nurse labor analgesia, only the anesthesiologist operation, given routine obstetric care. Anesthesia nursing group for labor analgesia by anesthesiologists and nurse by anesthesia on maternal perinatal period health education and pain management, pain score was compared between the two groups (at full dilatation), mode of delivery, postpartum hemorrhage, neonatal asphyxia. Results The total score of pain in the nursing group was 3.9±0.2, while that of the control group was 8.4±0.8, and the difference was statistically significant (t=-38.5872,P=0.000); anesthesia nursing group cesarean delivery, delivery, were 1 cases, 27 cases, 12 cases; the control group were 9 cases, 21 cases, 10 cases, the difference was statistically significant (χ2=7.31, P<0.05) ; the amount of bleedingof anesthesia nursing group (175.5±42.5) ml; the control group was (226.4±52.5) ml, the difference was statistically significant (t=8.621, P<0.05); the incidence of neonatal asphyxia anesthesia nursing group 1 cases (2.5%); the control group was 3 cases (7.5%), the difference was not statistically significant (χ2=0.263, P>0.05). Conclusions During the perinatal period, the labor management and nursing intervention of the parturient women with labor analgesia are significantly reduced, the cesarean section rate is significantly reduced, and the complication rate is reduced.

Objective To investigate the efficacy and safety of laparoscopic operations of ovarian tumors in children.Methods A total of 24 children with ovarian tumors treated laparoscopically from January 2000 to March 2005 were studied.The laparoscopic operations(tumor enucleation or unilateral adnexectomy) were conducted under general anesthesia with endotracheal intubation.Electrocoagulation of the capsule was performed alongside the borderline of the lesion for tumors 5 cm in diameter.After blunt dissection of the tumor and capsule,the lesion was completely enucleated.Hemostasis of the residual cut surface was accomplished by using electrocoagulation,with no need of suture. For large ovarian cysts disturbing laparoscopic visualization,the aspiration of hydatid fluid was conducted before the enucleation.Results All the operations were successful completed under laparoscope,including 24 cases of tumor enucleation and 2 cases of unilateral adnexectomy.The operation time was 50?20 min,the amount of hemorrhage was 30?10 ml,and the postoperative hospital stay was 2~4 d.No surgical complications or wound infection occurred.Follow-up in the 24 cases for 1 year found no recurrence.Conclusions Laparoscopic operations for ovarian tumor in children is safe and effective.

Objective To explore the value of Ligasure and Ultracision in total laparoscopic hysterectomy (TLH). Methods From January 2002 to December 2006,totally 225 patients received total laparoscopic hysterectomy in our hospital. Among the cases,Ligasure was used in 152 patients,and Ultracision were employed in 72. The clinical data of the patients were reviewed. Results The mean operation time in the Ligasure group was significantly shorter than that in the Ultracision group [(104.9?29.2) min vs. (152.4?46.6) min,t=-9.329,P=0.000]. And the mean blood loss of the Ligasure group was significantly less than that in the other group [(32.9?14.9) ml vs. (126.4?12.1) ml,t=-46.710,P=0.000]. In both the groups,no patient was converted to open surgery or developed complications or surgical injuries. Conclusions Both Ligasure and Ultracision are safe and effective for total laparoscopic hysterectomy. Ligasure is superior in the management of uterine vessels,while the Ultracision is more effective in opening the vesicle and separating the cardinal ligament.

ObjectiveTo compare the therapeutic efficacy of acupuncture at Diji (SP8) versus acupuncture at Dijiand Guanyuan (CV4) in treating primary dysmenorrhea, for exploring the combination relation of the commonly-used acupoints in acupuncture treatment for primary dysmenorrhea.MethodForty patients with primary dysmenorrhea were randomized into a single acupoint group and a double acupoint group, 20 in each group. The single acupoint group was intervened by acupuncture at Diji, while the double acupoint group was by acupuncture at Diji and Guanyuan. The change of Visual Analogue Scale (VAS) score was observed and compared between the two groups.ResultThe changes of VAS score in the double acupoint group were more significant than that in the single acupoint group at each different time point.ConclusionAcupuncture at Diji alone and acupuncture at Diji and Guanyuan both can effectively treat primary dysmenorrhea; however, acupuncture at Diji and Guanyuan tends to produce a more significant effect than acupuncture at Diji alone; Diji and Guanyuan may work synergistically in acupuncture treatment for primary dysmenorrhea.

Sal-like 4 (SALL4) plays an important role in promoting the cellular proliferation and maintaining the pluripotency of embryonic stem cells and tumor cells.In fully differentiated cells,the expression of SALL4 is silenced or down-regulated.However,the expression of SALL4 is found to be restored or up-regulated in a variety of non-germ cell tumors.Besides,the expression of SALL4 is often associated with disease progression,treatment effect and prognosis.Therefore,examining the expression level of SALL4 will be of great importance in the diagnosis of disease and monitoring the disease progression for non-germ cell tumors.

Objective To investigate the effects of Livin antisense oligonucleotide (ASODN) on the proliferation and apoptosis of human leukemia (K562) cells. Methods Specific phosphorothioate ASODN and missense oligonucleotide (MSODN) target Livin mRNA were synthesized and transfected into K562 cells following cationic liposome. The proliferation inhibition of K562 cells was assessed by MTT. The apoptosis rate of each group was detected by Annexin V-FITC. The expression of Livin mRNA was detected by reverse transcription polymerase chain reaction (RT-PCR). Results ASODN at a final concentration of 600 nmol/Lcould inhibit the K562 cells proliferation (IR) was (52.99t2.67) % and the expressions of Livin mRNA (ODR)was (59.75±3.24) %, the apoptosis rate was apparently increased [(36.89±1.08) %] (P ＜0.01); but the difference between Lip-MSODN group, Lip control group and cell control group was not statistically significant (P ＞0.05).Conclusion Livin ASODN may decrease Livin gene expression, suppress K562 cells proliferation effectively, and induce significant apoptosis of K562 cells.

Objective To investigate the effect of different pressures of hyperbaric oxygen (HBO) treatment on neuropathic pain (NP) in rats.Methods Twenty-four healthy male Sprague-Dawley rats were randomly divided into 4 groups (n =6 each):sham operation group (group S),NP group,treatment with HBO at 2.0 atmosphere absolute group (group HBO2.0) and treatment with HBO at 2.5 atmosphere absolute group (group HBO2.5).The animals were anesthetized with intraperitoneal 5 ％ chloral hydrate 300 mg/kg.NP was induced by chronic constrictive injury.The left sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1-mm intervals with 4-0 silk thread.After the rats were placed in the HBO chamber,the pressure was increased at a rate of 10 kPa/min until the desired pressure was reached,and then the pressure was maintained at this level for 60 min.The pressure was then decreased at a rate of 10 kPa/min until the normal pressure was reached.HBO treatment was performed once a day for 5 consecutive days starting from 1st day after operation in groups HBO2.0 and HBO2.5.While the rats were only placed in the HBO chamber and stayed for 100 min in groups S and NP.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 0,1and 2 h after leaving the HBO chamber (T0.2).Results Compared with group S,MWT was significantly decreased and TWL was shortened in group NP (P ＜ 0.05).Compared with group NP,MWT was significantly increased and TWL prolonged at T1 during the treatment (P ＜ 0.05),while no significant change was found in MWT and TWL at T2 during the treatment in groups HBO2.0 and HBO2.5 (P ＞ 0.05).There was no significant difference in MWT and TWL at each time point during the treatment between groups HBO2.0 and HBO2.5 (P ＞ 0.05).Conclusion Treatment with different pressures of HBO can reduce NP in rats,but the change in pressure dose not affect the analgesic efficacy.

Objective To investigate the possible pathway of FITC-dextran to the cochlea after post-aural injection.Methods The FITC-dextran(weight between 3 000~5 000) was chosen as a tracer in this study.A total of 200 suckling mice were randomly divided into four groups, with 50 in each group.Each animal was then administered with FITC-dextran or dextran via either post-auricular or intra-muscular injection, to a total dose of 20 μl (5 mg/ml).Samples were obtained at 0, 1/12, 1/4, 1/2, 1, 3, 5, 7, 12, and 24 hours after adminstmiceion, and the confocal technique was used to observe the distribution of the tracer.Taking into consideration the influence of spontaneous fluorescence, the fluorescence intensity ratio of the experimental and control groups was used as the final statistical data.Results FITC-dextran injected intramuscularly group: The fluorescence signal can be detected in the sigmoid sinus(SS) 3h after management, while in endolymphatic sac and cochlea at 12 h.FITC-dextran injected post-aurally group: After administration, an obvious fluorescence signal could be observed in the sigmoid sinus and endolymphatic sac immediately, cochlea at 30 min.The signal of the sigmoid sinus, endolymphatic sac and cochlea gradually increased successively, peaked at 5~15 min, 30 min and 60 min, and then decreased gradually.At 12 h, another small increases appeared, and the signal could not be detected at 24 h.Conclusion Compared with intramuscularly application, post-auricular injection can allow the drug to directly reach the endolymph.It is possible that the tracer first gathered in the SS via local blood circulation or infiltration, then entered the ES via micro-circulation around, and eventually arrived at the cochlea.
