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.

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.

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.

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.

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 clinical outcome of the technique of step-by-step in situ rod bending used in posterior internal fixation of lumbar burst fractures.Methods A retrospective case control analysis was conducted on 76 cases of lumbar burst fractures hospitalized between March 2007 and March 2014.There were 48 males and 28 females,with a mean age of 40.4 years (range,18-57 years).Fractured segments included L1 in 32 cases,L2 in 24,L3 in 14 and L4 in 6.According to the different rod bending methods,the subjects were divided into preliminary rod bending group (34 cases) and in suit rod bending group (42 cases).Operation time,amount of bleeding during and after operation,restoration of anterior vertebral height and Cobb angle,and visual analogue score (VAS) were compared between groups.Results Seventy patients were followed up for 12-36 months (mean,20.9 months).One patient in preliminary rod bending group presented internal fixation loosening,and had implant removal 9 months after operation.No implant breakage occurred.Comparison of preliminary rod bending group and in situ rod bending group showed significant differences in operation time [(88.1 ± 16.0)min vs.(79.9 ± 14.7)min],amount of bleeding during operation [(88.3 ± 21.2) ml vs.(74.0 ± 12.5) ml],amount of bleeding after operation [(71.5 ± 17.3)ml vs.(62.1 ± 16.0) ml],restoration of anterior vertebral height [(74.1 ±7.8) ％ vs.(79.5 ± 8.5) ％],and restoration of Cobb angle [(10.2 ± 2.7) °vs.(8.8 ± 2.6) °] (P ＜0.01 or 0.05).VAS presented no significant differences between preliminary rod bending group and in situ rod bending group before operation [(7.5 ± 0.9) points vs.(7.2 ± 1.0)points] and 1 week after operation [(2.9 ± 0.7) points vs.(3.0 ± 0.7) points] (P ＞ 0.05),while there was significant difference 9 months after operation [2.2±0.7)points vs.(1.9 ±0.7)points] (P＜0.01).Conclusion In suit rod bending for lumbar burst fractures has advantages over preliminary rod bending in terms of operation time,blood loss,precise restoration and back pain.

AIM: To analyze the common causes and treatments methods of high intraocular pressure (>21mmHg) after trabeculectomy.
METHODS: Twenty-four eyes of glaucoma patients with high intraocular pressure after trabeculectomy in our hospital from July 2010 to September 2014 were retrospectively studied. The common cause and processing methods were analyzed.
RESULTS:The causes which lead to early postoperative high intraocular pressure included high filtering bleb scar in 11 eyes ( 46%) , filtration obstruction in 4 eyes ( 17%) , malignant glaucoma 3 eyes ( 12%) , iris resection of malignant glaucoma unreasonable 2 eyes ( 8%) , hyphema 2 eyes ( 8%) , wrap cystic filtering bleb 2 eyes (8%), etc. After proper treatments, intraocular pressures of all patients were bellowed 21mmHg.
CONCLUSION: High intraocular pressure with surgery for glaucoma is caused by multiple factors, preoperative and intraoperative avoid as far as possible, postoperative early detection for symptomatic treatment is the key to successful operation.
