Objective To probe into the chnical value of strain rate imaging on the assessment of left atrial function in patients with hypertensive disorder comphcating pregnancy(HDCP).Methods Thirty two patients with HDCP and 20 control subjects were involved.Patients with HDCP were divided into 2 groups:17 with normal left ventricular mass index (LVMI) and 15 with left ventricular hypertrophy.These patients and controls underwent transthoracic echocardiography,strain and strain rate imaging examination.Atrial strain and strain rate imaging values of patients with HDCP were compared with those of controls.Multiple parameters were compared by one-way anova analysis.Results When compared with the controls,peak early diastolic strain rate (ESR) was significantly decreased in HDCP patients with normal LVMI and left ventricular hypertophy [(-1.13 ± 0.15),(-1.04 ± 0.29) s-1 vs.(-1.26 ± 0.23) s-1,P ＜ 0.05].Compared with the normal LVMI,peak late diastolic strain rate (ASR) was significantly decreased in controls and patients with left ventricular hypertrophy [(-1.23 ± 0.25) s-1 vs.(-1.36 ± 0.33),(-1.34 ± 0.32) s-1].There was no significant difference in the others (P ＞ 0.05).Conclusion Left atrial function is decreased in HDCP patients,which with left ventricular hypertrophy,the tendency is more obvious.

A L-arginine-producing mutant UN100-12(SG~(r),AE~(r)) was derived from Corynebacterium glutamicum ATCC138761 by combination treatment with ultraviolet(UV) and N-methyl-N-nitro-N-nitrosoguanidine(NTG). It could accumulate 16.6g/L L-arginine in the medium containing glucose as carbon source and ammonium sulfate as nitrogen source, when it was culrured at 30℃ for 4 days. And also this mutant has good stability of descendiblity of L-arginine.

Objective:To evaluate the diagnostic value of 18G and 16G needle biopsy of breast lesions.Methods: Onr hundred and fifteen patients with breast lesions those were excised through surgery. Each lesion was under ultrasound-guided needle biopsy(US-CNB) with 18G and 16G, then underwent surgical resection of mass and pathological histology. Histological findings of US-CNB and the surgical specimens were analyzed for sensitivities, false negative rates, and underestimate rates.Results: Among 84 cases of breast cancer proved by surgical pathology, the sensitivity, specificity, false negative rate of 18G and 16G biopsy diagnosis were followed by 95.2% and 97.6%, 89.6% and 94.3%, 4.8% and 2.4%. Paired chi-square test showed no significant difference between the two methods.Conclusion: 18G and 16G needle biopsy has no significant difference in the diagnosis of breast lesions.

As an important device of modern medical treatment,medical monitor is a combination of modern electronics technology,computer technology and medical technology.In this paper,the development of medical monitors in China is summarized,especially the main technique characteristics of medical monitor in Chinese market.The examples of monitors made in China are presented.

Recent studies suggest that lacunar infarction is a high risk ischemic cerebrovascular disease highly correlated with the time, which optimistic prognosis is not as good as previously thought.In addition, the role of macrovascular diseases has not been paid attention, it is not conducive to secondary prevention and early intervention for the etiology of lacunar infarction.This review focu-ses on application of imaging diagnosis of lacunar infarction, the etiology of non-lacunar infarct, and differential diagnosis of lacunar in-farction.

Objective To understand the clinical features,differential diagnosis,treatment and prognosis of postpartum hemolytic uremic syndrome (PHUS). Methods Three PHUS cases and relevant literature were reviewed. Results Three patients were admitted because of microangiopathie hemolytic anemia,thrombocytopenia and acute renal failure.which occurred within 3 days after cesarean section.All of them received plasmapheresis and hematodialysis.Now,one of the patients recovered,and the other lives on hematodialysis. Conelusiom Early diagnosis and proper treatment of PHUS ensures a better outcome.

Objective To investigate the different expressions of various subtypes of human leukocyte antigen-G(HLA-G)mRNA in placentas among early and late-onset severe preeclamptic and normal pregnant women. Methods Eleven placental samples from early-onset severe preeclamptic pregnancies and fourteen from late-onset severe preeclamptic pregnancies were collected as study group;eight placental samples from normal pregnancies were collected as control group.The levels of HLA-G mRNA in the three groups were measured by nested RT-PCR. Results Compared with the counterparts in the control group,the leveI of HLA-G1 subtype was significantly decreased (median:Early-onset group:1.37,P<0.05;Late-onset group:24.90,P<0.05;Control group:46.67,P<0.05)and the level of HLA-G5 subtype increased(median:Early-onset group 19.23;Late-onset group:3.65;Control group:1.33)in both early and late-onset severe preeclamptic group.The level of HLA-G2 subtype increased(median:Early-onset group:0;Late-onset group:21.59,P<0.05;Control group:5.39)in the late-onset severe preeclamptic group. Conclusion The reduced expression of HLA-G membrane-bound subtype mRNA in the placenta and the increased expression of HLA-G soluble subtype mRNA in the placenta may be related tO the pathogenesis of preeclampsia.
