Objective To determine the correlations between breast ultrasonic and mammographic features and molecular classification of breast infiltrating ductal carcinoma in young women.Methods A retrospective review of radiological,clinic-pathology features of breast cancers for women under 40 years at our hospital between January 2011 and May 2016 covering 94 patients.Mammography and ultrasound were available for all 94 patients.Results On sonography,basal like type tumours more often appeared as oval or round masses and microlobulated or indistinct margins luminal type irregular mass and angular or spiculated margins(P =0.000,P =0.000).Basal like type masses were often with abrupt interface,luminal A type with echogenic halo (P =0.000).On mamography,HER-2 enriched type cancers more presented as microcal cification only,basal likc type more masses(P =0.002).Luminal typc masses were more often with spiculated or obscured margins,basal like with indistinct margins(P =0.000).Conclusion The imaging charasteristics of breast infiltrating ductal carcinoma in patients under 40 years appear correlated to breast infiltrating ductal carcinoma.

Objective We used the DNA methylation microarrays to investigate the differential methylation genes and loci sites in Kashin-Beck disease (KBD),to study the relationship between DNA methylation and KBD pathogenesis.Methods Totally 12 KBD adults and 12 healthy adults were selected and peripheral blood samples were collected and DNA was extracted.Illumina 450K bead-chip was applied to detect methylation status in KBD and healthy controls.Aberrant hyper-methylated sites were filtrated according to the P value after correction and methylation differences,together with GenomeStudio soft.Screened genes were validated using bisulfite sequencing polymerase chain reaction (BSP) technology.Results A total of 484 948 loci sites were analyzed and compared,93 differential methylated loci were found by comparing KBD and normal people,including 34 hypermethylated sites and 59 hypomethylated sites.There were 50 genes corresponding to the loci,43 genes not reported in literature.According to gene ontology analysis,the genes were involved in the immune response,antigen processing,phosphate and phosphoric acid metabolism and phosphorylation and the process of metal ions in combination.However,in the verification test using BSP method,there was no significant difference in methylation rate in human leukocyte antigen (HLA)-DRB1 between the case and the control group (48％ vs 70％,x2 =3.688,P ＞ 0.05).Conclusions The high and low differentially methylated sites in peripheral blood DNA of KBD patients are significantly different from those of the health control.HLA-DRB1 locus is not significantly different between the BSP verification test and methylation chip.

Objective To investigate the potential factors affecting the survival rate of extremely low birth weight infant (ELBWI) and to make out a practical strategy. Methods Fourty-four ELBWI were devided to 3 groups according to their birth weight. All the clinical data were reviewed. Results The survival rate on discharge was 52% (22/42) and the mortality rate was 45%(19/42). The survival rate was significantly increased with higher birth weight( P

Objective To study the complications and the outcome of different type of twin pregnancy. Methods Three hundred and thirty two cases of twins from 1981 to 2000 were analyzed retrospectively. Results The incidence of twins is 8.63%.The common complications were pregnancy induced hypertension, premature rupture of fetal membranes, anaemia, premature labor and postpartum hemorrhage. There were no differences between the monozygotic twins and dizygotic twins in the incidences of these complications. The incidence of one fetal death in monozygotic twins was higher than that of the dizygotic twins (P

Objective To seek optimum extraction conditions of Radix Scutellaria in Qinbai ointment by studying on extraction process. Method The optimum extraction regard baicalin as the index. It was investigated by the orthogonal design and determined by HPLC. Result The effect of alcohol concentration has extremely remarkable difference (P

Objective To explore the effect of lidocaine combined with ropivacaine in penile dorsal nerve block for pediatric circumcision.Methods 130 children with pediatric circumcision surgery were divided into observation group and control group by the digital meter method,65 cases in each group.The control group was taken inhaled sevoflurane composite static note ketamine surgery,the observation group was given ropivacaine combined with intravenous infusion of ketamine for penile dorsal nerve block anesthesia.The anesthesia effects of the two groups were recorded.Results In the observation group,10 min after surgery,the rhythm of the heart was (98.47±10.88)times/min,central arterial pressure was (65.13±7.78)mmHg.In the control group,10min after surgery,the rhythm of the heart was (121.78±15.23)times/min,central arterial pressure was (85.27±12.31)mmHg,the differences between the two groups were statistically significant(t=10.040,11.150,all P＜0.05).In the observation group,the used ketamine,waking up time,pain score,incidence rate of pain and irritability were (41.38±11.28)mg,(5.54 ±1.03)min,(2.11±1.13)points,7.69％,respectively,which in the control group were (71.47±16.82)mg,(13.67±2.57)min,(3.89±1.79)points,26.15％,respectively,the differences between the two groups were statistically significant(t=11.978,23.673,6.779,χ2=7.878,all P＜0.05).Conclusion The anesthesia effect of lidocaine combined with ropivacaine in penile dorsal nerve block for pediatric circumcision is stable,safe and reliable,it is worthy of popularization and application in clinic.

Objective To investigate the effect of Fuxin tablet on thrombus formation in the arteries in rats and aggregation of platelet in rabbits. Methods To observe the effect of OT in the arteries through electric stimulation of common carotid artery. To observe the aggregation of platelet by using the PRP of the rabbit and ADP as the accelerant. PAG-1, PAG-3, PAG-5 and PAG-M were examined in the normal saline group and high-dose, middle-dose, low-dose groups of Fuxin tablet. Results High-dose and middle-dose groups of Fuxin tablet could prolong OT and decrease the aggregation of platelet. Conclusion Fuxin tablet could significantly inhibit the formation of thrombus in the arteries and maximal aggregation rate of platelet.

Objective To evaluate the effect of intrathecal administration of ?-conopeptide SO3 on inducible nitric oxide synthase(iNOS)expression of spinal cord and the ligated sciatic nerve in a rat model with chronic constriction injury(CCI).Methods 40 male SD rats were randomly divided into 4 groups of 10 animals each.Rats in the N group served as controls;in group C 4 loose ligatures were placed around the right sciatic nerve for 14 days;in group CN,normal saline 1?l/h was injected intrathecally slowly for 7 days seven days after the ligation;in group CS,?-conopeptide SO3 30ng/h was administered intrathecally slowly for 7 days seven days after the ligature.Local expression of iNOS was assayed in samples taken from injured nerves(between and distal to the CCI site)and the spinal cord using Western blotting analysis,with GAPDH as an internal reference.Results A 130 kDa band,corresponding to iNOS protein was detected in the middle and distal sections of the injured nerves and the spinal cord.The iNOS immunoreactivity was inhibited by continuous intrathecal injection of ?-conopeptide SO3.There was no difference in the expression of iNOS between group CN and group C.Conclusion The expression of iNOS in the spinal cord and injured nerves of CCI rats was enhanced.Intrathecal injection of ?-conopeptide SO3 can inhibit the expression of iNOS.The data suggested that N-type calcium channel blocker took part in the expression of iNOS.

Objective To investigate urinary tract injuries in laparoscopic-assisted vaginal hysterectomy(LAVH).Methods Clinical data of 5 cases of urinary tract injuries from 415 cases of LAVH from December 1995 to January 2006 in this hospital were retrospectively studied. Results Intraoperative bladder injury occurred in 2 cases and an immediate repair was given.Postoperative ureteral injury occurred in 3 cases: 2 cases of ureteral injury were found 4 days after operation because of abdominal pain,and 1 case was found on the 30th day after operation because of massive vaginal discharge.Conclusions Urinary tract injury is one of common complications in laparoscopic-assisted vaginal hysterectomy.High-risk factors include tumor size more than 5 cm,tumor protruding to the broad ligament,and tumor adjacent to the isthmus.Surgical repair is the major treatment.
