10 mg?kg -1?d -1? 5 d. The inhibitory rate of ZD1694( 0.001- 1 000 mmol?L -1)on SGC-7901 cells were increased in concentration and time-dependent manner. The cell numbers in G_0-G_1 phase in SGC-7901 cells were raised by ZD1694 as well. CONCLUSION: ZD1694 can take obvious antitumor effects on S180-bearing mice. The antitumor rate of ZD1694 is in a dose-dependent manner, and it is higher when the total dosage is administered in one day than that the total dosage was divided into 5 consecutive days. ZD1694 can inhibit the growth of SGC-7901 cells and block the cells in G_1 phase in vitro.

Objective To investigate the clinical value of the YSZ-1 uterine manipulator in total laparoscopic hysterectomy.Methods Total laparoscopic hysterectomy was employed in a total of 78 women by using the LigaSure,ultrasonic scalpel,and the YSZ-1 uterine manipulator.The anterior fornix was opened and the manipulator was placed on the lip of the cervix.Then the uterus was completely removed.Results The operation was completed smoothly in all the 78 patients.The operating time was 45~90 min(mean,63 min),and the intraoperative blood loss was 40~100 ml(mean,65 ml).No urinary tract injuries,vaginal bleeding,or other postoperative complications occurred.The length of postoperative hospital stay was 4~7 d(mean,5.3 d).Follow-up examinations in the 78 patients for 3~6 months(mean,4 months) showed that the vaginal wound normally healed up. Conclusions Use of the YSZ-1 uterine manipulator in total laparoscopic hysterectomy makes the procedure easier and safer.The YSZ-1 uterine manipulator is a useful laparoscopic instrument.

Objective To evaluate the efficacy of the parathyroidectomy (PTX) in the treatment of severe secondary hyperparathyroidism (SHPT) with Sagliker syndrome (SS). Methods A retrospective review was undertaken among 212 SS patients underwent PTX in our hospital and with more than 3 years' follow up. The definitions of the efficacy were based on the postoperative intact parathyroid hormone level (iPTH). Cure showed that the iPTH was ＜ 150 ng/L; marked effectiveness was 150-300 ng/L; effectiveness was 301-500 ng/L;ineffectiveness was ＞500 ng/L. The status was defined as persistent SHPT if iPTH was ＞ 150 ng/L after surgery. The status was considered as SHPT recurrence if iPTH was ＜ 100 ng/L in the first week after surgery, and gradually increased and ＞ 150 ng/L with the follow-up. Results ( 1) Ten patients were involved and the average dialysis time was 142 months [male/female: 4/6; age 30-54 (39. 3 ± 10. 4) years]. All patients had severe bone and joint pain, accompanied with progressive facial increases, chicken breast, kyphosis, hip bone deformities, and body height shortening. (2) Preoperative tests: the median of iPTH 2000(1800-2863) ng/L; serum calcium (2. 45 ±0. 21) mmol/L, phosphorus (2. 19 ±0. 51) mmol/L, alkaline phosphatase ( ALP) (1189. 8 ± 780. 0) IU/L. Two to four enlarged parathyroid glands were confirmed by ultrasound and 99Tcm-MIBI parathyroid scintigraphy. ( 3 ) Surgical procedures: local or general anesthesia for PTX. Supplement with calcium and calcitriol implemented low serum calcium after PTX. (4) Follow-up: symptoms, including bone pain, muscle weakness, skin itching, and insomnia, were significantly improved after surgery. Transient hoarseness occurred in 2 cases. The iPTHs of all patients were decreased significantly after surgery. The median of iPTH was 55.5 ( 10-967) ng/L at 1 month post PTX, and was significantly less than prior to PTX (P＜0. 001). Eight patients were cure , 1 marked effectiveness ,and 1 ineffectiveness. Two patients were persistent SHPT, and 1 died of heart failure in the 4th year after PTX. The development of bone deformities was stopped and malnutrition was improved in long-time follow up. The level of iPTH 135(28-390)ng/L(P＜0. 001 ) , serum calcium, phosphorus, and ALP showed normal in the third year. The SHPT recurrence was appeared in the 2nd and 3rd year in 2 out of 8 patients, respectively. Conclusions Total PTX can effectively treat SS by SHPT. It can improve prognosis for patients, such as bone pain disappearing, bone deformities stopping and malnutrition improving, etc. The level of iPTH may rise again in some patients in the future. Therefore, more attentions should be paid to monitoring.

Objective To assess the subgenotypes of pathogenic Cryptococcus gattii isolates from China and to elucidate the epidemiological links between these domestic isolates and those from other parts of the world. Methods DNA was extracted from 9 clinical isolates of Ctyptococcus gattii from China. The partially variable regions of the three unlinked loci, namely IGS1, PLB1 and GEF1, were amplified and sequenced, and the bioinformation at these loci was obtained from GenBank for multi-locus sequences alignment and phylogenetic analysis. Results Of these 9 clinical isolates, 8 were genotype VG Ⅰ and mating type α with the same sequences at the tested regions as the reference strain WM276, which was a representative isolate of an independent subgenotype; 1 was of genotype VG Ⅱ and mating type α, which was the first report in China, with the tested sequences consistent with those of the referrence strain R272. Sequencing and phylogenetic analysis of GEF1 gene, which was located at mating type locus, successfully identified the genotypes and mating types of all the Cryptococcus gattii isolates involved here. Conclusions Multi-locus sequence analysis shows that causative Cryptococcus gattii isolates of genotype VG Ⅰ in China carry similar sequences at the tested loci in IGS1, PLB1 and GEF1 genes, to a widely distributed subgenotype in the world, and the sequences of the first VG Ⅱ genotype isolate from China resemble the less virulent subgenotype VG Ⅱ b found in Vancouver islands.

AIM: To elucidate the anti-inflammatory mechanism of cholecystokinin octapeptide (CCK-8). METHODS: The pulmonary interstitial macrophages (PIMs) from rats were stimulated with LPS (1 mg?L~(-1)) in the presence or absence of CCK-8 (10~(-8)-10~(-6) mol?L~(-1)) or/and CCK receptor antagonist proglumide (2 mg?L~(-1)). The expression of TNF-? mRNA was assayed by reverse transcription polymerase chain reaction (RT-PCR) at 3 h of the stimulation, and nuclear factor-?B (NF-?B) binding activity was analyzed by electrophoretic mobility shift assay (EMSA) at 1 h of stimulation. The I?B? protein level in the cytoplasma at 30 min of the stimulation was detected by Western blot. RESULTS: CCK-8, at concentrations from 10~(-8) mol?L~(-1) to 10~(-6) mol?L~(-1) obviously inhibited LPS-induced TNF-? mRNA expression and NF-?B binding activity in a dose-dependent manner. Stimulation with LPS resulted in a reduction of I?B? protein level in PIMs, which was elevated by CCK-8. The effects of CCK-8 on NF-?B activity and I?B protein level were attenuated by CCK receptor antagonist proglumide. CONCLUSION: CCK-8 inhibits LPS-induced TNF-? mRNA expression by regulating NF-?B activity in rat PIMs, which is mediated through CCK receptors and inhibition of I?B? degradation. This represents one of the anti-inflammatory mechanisms of CCK-8.

Objective:To evaluate the effects of nutrition supplemented with glutamine on immune function and systemic inflammatory response in patients with severe craniocerebral trauma.Methods: Forty postoperative patients with severe craniocerebral trauma were randomized into experiment group(n=20) and control group(n=20).All patients received similar nitrogen and calorie for one week.Patients in experiment group were additionally supplemented with glutamine at dose of 0.50 g/(kg?d).Blood samples were obtained for measurement of IgM,IgG,IgA,CD3,CD4,CD8,CD4/CD8 before and after nutrition support the systemic inflammatory response syndrome(SIRS)was observed daily,and the serum albumin,transferin,hemoglobin and GCS were detected before and after nutrition support.Results: IgG,IgA,CD4,CD4/CD8,GCS and transferin in experiment group increased significantly after nutrition than in control group.Conclusion: Nutrition supplemented with glutamine may improve immune function,GCS and transferin in patients with severe cranial trauma.

Objective The clinical value of ifrst-trimester standard ultrasound views in screening for fetal structural abnormalities. Methods From September 2008 to March 2011, transabdominal sonographic screening by standard ultrasound views was performed in 3 134 viable singleton pregnancies during the ifrst trimester at Beijing Obstetrics and Gynecology Hospital. Used the following views:(1) Fetal proifle;(2) Neck sagittal;(3) Skull and brain;(4) Thorax;(5) Abdomen;(6) Bladder;(7) Upper limbs, and (8) Lower limbs. The women underwent 20-to 24-week and 28-to 32-week ultrasound examination if the anatomical survey was normal during the ifrst trimester. Follow-up was obtained by reviewing of the birth records from hospital charts. Results Sixteen prenatal abnormalities were detected at 11-to 13-week scan (including one case of encephalocele and meningoceles, one case of endothelial cushion defect and single umbilical artery, one case of ectopia cordis, gastroschisis, and spinal abnormalities, two cases of exencephaly, one case of anencephaly, one case of gastroschisis and lower limb malformation, two cases of omphalocele, one case of encephalocele, ectopia cordis, and gastroschisis, one case of single ventricle, one case of endothelial cushion defect, four cases of hyhrop). All of the 13 women decided on termination of pregnancy. Three suspected structural abnormalities (hydrops) detected at the ifrst-trimester scan were found as normal after birth. Seven cases were diagnosed at 20-to 24-week scan (including one case of dextrocardiac and double outlet right ventricle;two cases of endothelial cushion defects;one case of trisomy 21 with VSD;one case of omphalocele, one case of short ulna and radial with wrist distortion, and one case of club foot). One case of diaphragmatic hernia was detected at 32-week scan. Two cases (one case of cardiac defects and one case of ear deformity) were identified after birth. Of all the 3 134 fetuses, follow-up was obtained in 2 822 cases, 312 cases were excluded from the analysis because the outcome of their pregnancy could not be traced. Twenty-three fetuses with at least one major structural defect detected by prenatal ultrasonography were confirmed by follow-up. The sensitivity of the standard first-trimester ultrasound views was 56.5%(13/23), speciifcity was 99.9%(2 796/2 799), CR was 99.6%(2 812/2 822), and the false negative rate was 43.5%(10/23). Conclusions The standard views of the ifrst trimester are feasible and effective in screening the major fetal abnormalities including exencephaly, anencephaly, gastroschisis, omphalocele, ectopia cordis and single ventricle. However, ultrasound screening in early pregnancy still has some limitations, continuous scanning in different stages of pregnancy is necessary.
