Objective To explore the effect of soup of promoting blood circulation and promoting pregnant on the ovulation function of sterility caused by endometriosis.Methods 60 cases of endometriosis had been randomly divided into treatment group(30 cases)and control group(30 cases),the treatment group treated by the traditional Chinese drug and the control group treated by nemestran.Results After 6 menstrual cycles,the pregnant rate in the test was 50.O%and the control,33.3%.There was no significant difference between two groups(P＞0.05).The diameter of ovarian follicle and the number of mature ovarian went up,there were significant difference in combination with the fro and post-treatment(P＜0.01).The incidence of premature lutionization follicle syndrome(LUFS)caused by ovarian cracking tend tO get down,there were significant difference in combination with the fro and post treatment(P＜0.05).Conclusion The soup of promoting blood circulation and promoting pregnant has effect of improving the growth of ovarian follicle,increasing ovulation and making the chance of pregnancy.

Objective To establish stable Graves disease (GD) mice models with immunization and electroporation (EP).Methods Fifty mice were divided into 3 groups by random number table method:experimental group (n =30),control group (n =10),blank group (n =10).Recombinant plasmid pcDNA3.1/hTSHR268 was constructed and injected to bilateral gastrocnemius in experimental group mice on the 1st,4th,7th and 10th week.The same volume of normal saline was injected in the control group and blank group at the same time.Both experimental group and control group were subjected to EP at the same time and the same location to enhance immunization.Serum T4 was tested with radioimmunoassay.TRAb N-terminal (TRAb N) and TRAb C-terminal (TRAb C) antibodies were tested with ELISA.Whole body 99TcmO4-imaging was performed and then thyroid morphology and pathology were investigated.Data were analyzed by one-way analysis of variance and the least significant difference (LSD) t test.Results GD BALB/c mice models were built successfully (80％,24/30).Serum T4 increased from (16.06±5.16) nmol/L at the basic level to(95.04±68.92) nmol/L on the 12th week(F=18.906,t=-5.598,P＜0.05).Serum TRAb N antibody increased from (0.006±0.002) U/L at the basic level to (0.251±0.110) U/L on the 12th week(F=47.491,t=-10.869,P＜0.05).Serum TRAb C antibody increased from (11.176±2.635)×103 arbitrary unit (AU)/L at the basic level to (46.395±22.001)× 103 AU/L on the 12th week(F=14.642,t =-7.787,P＜0.05).On the 18th week serum T4,TRAb N and TRAb C decreased to (36.64±23.68) nmol/L,(0.094±0.053) U/L and (24.456±6.725)× 103 AU/L respectively,which were still higher than those preimmune levels(t=-4.161,-8.085,-9.008,all P＜0.05).There were no significant change of T4,TRAb N and TRAb C in the control group and blank group.After 4 times of immunization,the 99TcmO4-uptake by thyroids in immunized mice increased.The thyroid glands of immunized mice showed enlargement.Microscope examination showed that there were lymphocytes infiltration,colloid decrease and epithelial cell proliferation in thyroids of immunized mice.Conclusion GD mice models were successfully established by injecting recombinant plasmid pcDNA3.1/hTSHR268 and EP.

Objective To explore the possibility of using 131I as a targeted therapy method for malignant glioma by infecting U87 and U251 cells with conditionally replicative adenovirus Ad-Tp-E1a-Gp-NIS.Methods Human telomerase reverse transcriptase (hTERT) promoter and glial fibrillary acidic protein (GFAP) promoter were cloned and their transcriptional activities were detected by luciferase assay.The conditionally replicative adenovirus Ad-Tp-E1 a-Gp-NIS was constructed,purified,and transfected into U87 and U251 glioma cells.For these transfected cells,the selective replication ability was evaluated by plaque forming assay,and protein expression was detected by Western blot assay.125I-iodide uptake and exflux,the clonoy formation of 131I-iodide treated cells were also measured.Results Transcriptions activity of the GFAP and hTERT promoters was 59.75％-62.10％ (F =11.89,P ＜ 0.01) in U87 cells and 37.31％-49.00％ (F =5.87,P ＜ 0.05) in U251 cells.The Ad-Tp-E1a-Gp-NIS could be selectively replicated and the hNIS gene was successfully expressed in the hTERT-positive and GFAP-positive glioma cells which showed two protein bands with relative molecular mass of 120 × 103 and 49 × 103 in Western blot assay.After infection with Ad-Tp-E1a-Gp-NIS,the cell ability of 125I uptake was increased by 78.80 (F =2 914.58,P ＜0.01) and 92.48 (F =2 275.91,P ＜0.01) times in U87 and U251 cells,respectively.The GFAP-negative MRC-5 cells could not take in 125I.The in vitro clonogenic assay indicated that,after 131I treatment,more than 90％ of the transfected cells were killed,while only about 65％ (t =11.73-78.33,P ＜ 0.01) of control cells were killed.Conclusions The Ad-Tp-E1a-Gp-NIS has a good ability in selective replication and the enhancement of antitumor therapy effect by increasing tumor-specific iodide uptake in malignant glioma cells.

Objective To evaluate the role of autologous septal cartilage in the rhinoplasty of the wide and bulbous nasal tip. Methods A big piece of autologous nasal septal cartilage was removed and transplanted to the front of nasal septum, acting as a septal extender to fix the nasal alar cartilage,and then the shape of nasal tip was reconstructed by middle crus suture technique, excessive soft tissue under skin of tip and a part of lateral crura cartilage were removed to stand out the shape of the nasal tip. Results After one year follow-up, 118 of 126 cases achieved satisfied effects, but 8 cases dissatisfied because of their undue thick skin. Conclusions This method is reliable in the correction of the wide and bulbous nasal tip.

Methods Based on previous test, xenografted ovarian cancer nude model were established in nude mice. The effects of radioactive isotope 99m TcO-4 imaging and radioiodine 131Ⅰ treatment on xenografted ovarian cancer in vivo were investigated. Results After transferring human sodium/iodide symporter (hNIS) gene, the xenografted ovarian cancer in nude mice was imaged by isotope 99m TcO-4 Moreover,131Ⅰ exerted inhibitory effect on the proliferative activity. Conclusion After the transfection of hNIS gene, 131Ⅰ has inhibitory effect on proliferative activity of xenografted ovarian cancer.

Objective To discuss the effect of transplanting autogenous rib cartilage in correction of short and upwardly rotated nose.Methods A piece of autogenous rib cartilage was transplanted into the front of nasal septa to lengthen it,leading to the nasal tip moving forwards and correcting the short and upwardly rotated nose.For low nose cases,simultaneous implants was used into the nasal back.Results The nasal tips were prolonged 0.75 cm on average after operation in 56 patients with short and upturned noses.The nasolabial angle and extent of nostril exposure were normal after operation.The operational consequences were fine in 54 patients,while 2 case were not satisfactory.Efficacy was stable during one year follow-up.Conclusions This method is reliable,and it can be recommended in rhinoplasty of patients with short and upwardly rotated nose.
