Objective To observe the early onset breast cancer ( EOBC) sonographic performance character-istics and explore the diagnostic value of ultrasonography in EOBC .Methods 60 cases EOBC patients younger than 35 years old were seclected as the observation group .Older than 35 years of 50 patients with breast cancer were se-clected as the control group .Two groups were underwent breast color Doppler ultrasound .Results 59 cases in 60 pa-tients with preoperative ultrasound diagnosis of breast cancer ,one case was misdiagnosed as mastitis pseudotumor infil-trating ductal carcinoma ,lobular carcinoma ,ductal carcinoma in ultrasound showed more direct signs ,medullary carci-noma showed more indirect signs .Clumps were main types of breast cancer of the observation group and control group , respectively,accounted for 72.9% and 87.5%,the difference was statistically significant (χ2 =6.293,P<0.05). Two groups of color Doppler richness , lesion shape , boundary definition , without hyperechoic halo , calcification and glitches levy or levy Crab compared were not significant (P>0.05);Compared with the control group ,heterogeneous internal echo,rear attenuation of observation group had significant differences (P<0.05).Foci were observed group EOBC anteroposterior diameter and aspect ratio were significantly lower than that of the control group ,the difference was statistically significant(t =6.720,9.285,all P <0.05);diameter was significantly higher (t =34.962,P <0.05).Conclusion Early-onset breast cancer at diagnosis with color Doppler ultrasound large diameter aspect ratio is small,and the rear common heterogeneous internal echo attenuation less characteristic features ,screening younger women for breast cancer is important .

Objective To analyze the efficacy of prophylactic dexamethasone in the treatment of aortic dissection with stent graft.Methods The clinical data of 87 patients who received aortic dissection with stent implantation were retrospectively analyzed.The treatment group(39 cases)was treated with dexamethasone on the basis of antibiotic prophylaxis to prevent infection,and the control group(48 cases)received antibiotics to prevent infection perioperatively.The curative effect was compared between the two groups.Results The degree of inflammatory reaction in the treatment group significantly reduced,and the treatment group had obvious curative effect(x2=54.88,P<0.01).The total effective rate,significant effective rate and effective rate of the treatment group were 92.31%,61.52%,7.70%,respectively,which were significantly higher than those of the control group(13.00%,6.25%,6.25%),the difference was statistically significant(x2=54.88,P<0.01).Conclusion Prophylactic use of dexamethasone in the treatment of systemic inflammatory response after aortic dissection with stent implantation has significant effect.

Objective To investigate the effectiveness and surgical techniques of the improved laparoscopic treatment of ovarian dermoid cyst to prevent the occurrence of intraoperative rupture of teratomat, so to preserve the ovarian function at the maximum. Methods The modified laparoscopic extra-cavity and cavity outside the teratoma removed surgical suture treatment from February 2005 to February 2009,39 cases with large dermoid cyst were trea-ted by improved surgery and 45 cases treated by normal removal of laparoscope. The rupture, surgery time, bleeding volume,frequency of use of electrocoagulation and the effect of body temperature on intestinal canal and hospitaliza-tion day after operation as well. Results 39 cases of dermoid cyst were successfully managed by improved laparo-scopie surgery, during which no cyst contents broke into the abdominal cavity, no one was placed on electrocoagula-tion to stop bleeding, bleeding volume was (35.13±5.49) ml, operative time was (36.07±12.53) min, significantly leas than that of normal laparoscopic surgery group [the cyst rupture rate was 46.7% (21/45), the frequency of elec-trocoagulation was (5.0±3.0) times, the duration of electrocoagulatian was (5.5±2.5) s, bleeding loss was (40.73±6.04) ml and the time for operation was (67.47±20.73) min], with significant difference between the two groups (P<0.05 or 0.01);howevere, there was no remarkable difference in the effect of the two types of surgery on postoperative body temperature,anal exhaust time,postoperative hospitalization day. Conclusions In addition to minimally invasive laparoscopic surgery in the treatment of gastro-intestinal effects of small, quick recovery, the im-proved laparoscopic surgery for dermoid cyst shortens the operation time. The improved abdominal cavity and suture outside the strip surgical method can effectively prevent the complication caused by intraoperative tumor capsule rup-ture,reduce electrocoagulation injury,and preserve the ovarian function at the maximum.

Objective: To determine the inhibitory effects of maltitol-gum on Streptococcus mutans, Lactobacilli and Actinomyces viscosus in dental plaque. Methods: Thirty 13-15 years old children with DMFS>4 were divided into three groups, maltitol chewing gums group(A group), xylitol chewing gum group(B group) and blank gum base group (C group). The plaque samples were collected and colony forming units were counted. Results: The levels of three-species cariogenic pathogens in three groups were statistically down-regulated when compared with the baseline(P<0.001).Moreover, A group and B group resulted in a higher decrease of Streptococcus mutans levels compare with C group(P<0.05). The levels of Lactobacilli and Actinomyces viscosus were not statistically different between groups(P>0.05). Conclusion: Maltitol-gum can lead to a significant suppression on Streptococcus mutans levels in dental plaque,while the inhibitory effect of the maltitol-gum on Lactobacilli, Actinomyces viscosus is not obvious.

Bone mineral density (BMD) of lumbar spines, femoral neck, Ward′s triangle and greater trochanter was lowered, serum calcium, phosphate, alkaline phosphatase and bone Gla-protein levels were raised, and vitamin D receptor (VDR) contents in lymphocyte was lowered in hyperthyroid patients. Both FT 3 and FT 4 were negatively correlated with BMD, suggesting that hyperthyroidism results in high-turnover type of bone loss which causes the abnormalities of bone metabolic indices and VDR content.

OBJECTIVE:To observe the efficacy of Methyl Carboprost-NEGPF administered per rectum at different time in preventing postpartum hemorrhage in patients with vaginal delivery.METHODS:A total of 300 parturients undergoing vagi-nal delivery with possible postpartum hemorrhage were enrolled:Methyl Carboprost-NEGPF 1 granule(1mg) per rectum (with a suitable inserting depth of 6 cm) were administered in Group A(n=100) when their uterine orifices were fully open and Group B(n=100) after fetal delivery,while Group C(n=100) were injected i.m with oxytocin 10IU after fetal delivery. The three groups were compared in respect of third stage labor duration,postpartum blood loss amount at 2h and 24h and case numbers with postpartum hemorrhage.RESULTS:As compared with Group A and Group B,Group C was significantly different in the duration of third stage of labor and postpartum blood loss amount at 2h and 24h(P

Objective To explore the protective efficacy of antioxidants (vitamin E and Ginkgo biloba extract) on the peripheral nerve damages induced by antiepileptic drugs (AEDs). Methods Adult (2-month old) and infant SD rats (7-day old) were respectively treated with AEDs (phenytoin,or phenobarbital,or clonazepam) alone,or simultaneously with vitamin E or Ginkgo biloba extract for 4 weeks. All the rats were sacrificed,sciatic nerves and serum were collected. The sciatic nerves were analyzed by histologically for their pathological changes,and serum and homogenate of sciatic nerves were investigated for their total antioxidative capacity and antioxidant enzyme activity. Results Incidence of pathological abnormalities of teased fibers significantly reduced in all rats treated with AEDs and antioxidants (P

AIM:To compare the effects of remifentanil and fentanyl for posterior scoliosis correction and the influences on postoperative pain.METHODS:Forty patients scheduled for posterior scoliosis correction(ASAⅠ-Ⅱ,aged 11-18 years)were randomly divided into group remifentanil(group R)and group fentanyl(group F).Anesthesia was maintained with propofol,vecuronium bromide and sevoflurane.Intravenous remifentanil(0.2 ?g?kg-1?min-1)and fentanyl(1 ?g?kg-1?h-1)were continuously administered for analgesia.Vecuronium bromide and analgesics were discontinued around 30 min before the wake-up test.The wake up time from propofol and sevoflurane discontinuation to movement of the patient's toe were recorded.In group R,once remifentanil infusion was stopped before surgery ended,the patients were injected with fentanyl 2 ?g/kg.All of the patients received intravenous fentanyl(10 ?g?kg-1?min-1)for postoperative analgesia and were interviewed for pain degree during the first 24 h after surgery.RESULTS:The wake-up time were(12.3?5.7)min in group R and(21.6?6.5)min in group F(P
