Objective:To investigate the patient-controlled intravenous analgesia effect of butorphanol combined with remifentanil in uterine artery embolization for uterine myoma. Methods:Totally 68 cases of uterine fibroids patients were divided into the observa-tion group (n=35) and the control group (n=33) according to the admission order, and with time selecting operation. The control group was given fentanyl for patient-controlled intravenous analgesia, while the observation group was treated with butorphanol com-bined with remifeatanil. VAS (visual analog scale), sedation, postoperative pain and adverse reactions in the two groups were ob-served and compared. Results:VAS and sedation score of the observation group were significantly lower than those of the control groups in 1, 4, 12 and 24 h after the operation (P<0. 05). Grade 0 pain rate was 74. 3% in the observation group after the operation, which was significantly higher than that in the control group (48. 5%, P<0. 05). The incidence of adverse drug reactions in the observation group was significantly lower than that in the control group (P<0. 05). Conclusion:The combination of butorphanol and remifentanil in uterine fibroid embolization can effectively reduce postoperative pain and significantly decrease the incidence of adverse reactions with promising safety and reliability, which is worthy of promotion in clinical use.

Objective: To study the application of CT and MRI fusion technique in the diagnosis and treatment of intraocular and orbital tumors. Methods: 2D-images of 13 patients with intraocular and orbital tumors were fused by special-point registration and Iterative Local Closest Point(ILCP) method; 3D-fusion images were reconstructed by Ray Tracing method. Results: A 3D-CT-MRI fusion images of intraocular and orbital tumors were reconstructed and displayed. The CT and MRI data of intraocular and orbital tumors were displayed on the same image as a comprehensive whole,which provided a stereogram of 3D-structure of the normal and abnormal orbital tissues. Anatomical structure of the orbit was clearly visualized by 3D-CT-MRI image. Conclusion: The multi-modality fusion technique can provide more accurate and comprehensive information for clinical diagnosis of intraocular and orbital tumors, which is helpful for doctors' planning of surgical operations,clinical education and doctor-patient communication.

20 children aged 3 years ±3 months with dental caries were randomly divided into 2 groups(n =1 0).The caries tissue was re-moved by conventional bur and Er:YAG laser respectively without the use of mouth speculum,mouth gag and binding belts.In laser group the success rate of treatment at first visit and return visit was higher(P <0.05)and children's dental anxiety grad was lower(P <0.05).The Er:YAG laser is more effective in easing children's dental anxiety and in the dental treatment.

Objective: To explore the value of implanted intensity-modulated bmchytherapy for recurred cervical carcinoma. Metheds: A total of 25 cases of recurred cervical carcinoma were enrolled into the trial group which were treated with pelvic implanted aftedoading intensity-modulated brachytherapy. The other 25 patients with recurred cervical carcinoma treated with routine brachytherapy during the same pedod were en-rolled into the control group. Results: There were 20 cases with CR and 5 cases with PR in the trial group, and 10 cases with CR, 7 cases with PR, 4 cases with SD and 4 cases with PD in the control group, with a signifi-cant difference between the two groups (P<0.05). In the trial group, there were 5 cases with vaginal-rectal fis-tula and 1 case with grade 3 enteritis. In the control group, there were 3 cases with vaginal-rectal fistula. Con-dusion: Pelvic implanted intensity-modulated brachytherapy for recurred cervical carcinoma is satisfactory with better short-term efficacy than that of the routine brachytherapy and tolerable side effects.

Objective To investigate the influence provided by irbesartan on aldosterone escape during an-giotensin-converting enzyme inhibitor(ACEI) therapy in patients with essential hypertension (EH). Methods 166 EH patients were treated with ACEI. Plasma angiotensin Ⅱ ( Ang Ⅱ ) and aldosterone(Ald) concentrations were meas-ured by radioimmunoassay following the therapy of 3 months treatment. Aldosterone escape was estimated by the plas-ma Ald level after 3 months treatment. Patients with aldosterone escape were given irbesartan for 6 months. The aldo-sterone escape were observed following the therapy with irebesartan at 1,3,6 months. Results Following the treat-ment of irbesartan for 1 month, plasma Ang Ⅱ and Ald concentrations significantly decreased (P < 0.01 ). However, it began to increase after 3 and 6 months treatment, still lower than that of the therapy not given irbesartan ( P < 0.01 ).The levels of plasma Ang Ⅱ and Aid were higher in 6 months than in 1,3 months ( P < 0.01 ), but there are no differ-ences between 1 and 3 months(P>0.05). Conclusion Irbesartan can reduce aldosterone escape during 6 months.But aldosterone escape may be occur again after 6 months treatment of irebesartan.

BACKGROUND: How to establish a stable in vitro culture system, including location of corneal limbal epithelial stem cells, in vitro sample harvest, in vitro culture, vector selection, as well as identification methods, play a key role in corneal limbal epithelial stem cells culture. OBJECTIVE: To culture the isolated rabbit corneal limbal epithelial stem cells and to identify the biological properties of cultured cells. METHODS: The primary rabbit cornel limbal epithelial stem cells were isolated and cultured with tissue inoculation using human amniotic membrane as vector. The growth features of cells were observed under an inverted microscope. The morphology of cells was observed by hematoxylin-eosin staining and a scanning electron microscope. Furthermore, the monoclonal antibody AE5 and P63 two-step immunohistochemical staining were used to identify limbal epithelial stem cell protein expression. RESULTS AND CONCLUSION: The rabbit corneal limbal epithelial stem cells could be successfully cultured and maintained a relatively high value-added potential in vitro. Rabbit corneal limbal epithelial stem cells cultured on the amniotic membrane pull netted cellular layer. The AE5 monoclonal antibody positive rate of primary cultured cells was about 5% and P63 monoclonal antibody positive up to 90%. AE5-positive rate increased and P63-positive rate decreased with the increase in the number of subculture. The rabbit limbal epithelial stem cells can be successful culture and amplified on human amniotic membrane in vitro by limbal tissue culture method. The cultured cells maintain the characteristics of corneal epithelial cells. The rabbit corneal limbal epithelial stem cells can form grafts on the amniotic membrane.
