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.

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 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.

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.

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.

OBJECTIVETo compare clinical outcomes of bilateral transpedicular balloon kyphoplasty for the treatment of ordinary osteoporotic vertebral compressive fracture (OVCF) and severe osteoporotic vertebral compressive fracture.

METHODSFrom Junary 2009 to Febuary 2011, 60 patients (70 vertebrae) with osteoporotic vertebral compressive fracture were included. All patients were treated by bilateral transpedicular balloon kyphoplasty combined with postural reduction, including 10 males and 50 females aged from 59 to 90 years old with an average of 72.1 years old. In ordinary osteoporotic vertebral compressive fracture group, there were 38 patients (44 vertebrae) including 7 males and 31 females aged from 59 to 87 years old with an average of (71.8±6.1) years old. There were 6 patients with two vertebral fractures, 1 vertebra in T9, 5 vertebrae in T10, 7 vertebrae in T11, 13 vertebrae in T12, 9 vertebrae in L1, 4 vertebrae in L2, 4 vertebrae in L3, 1 vertebra in L4. While in severe osteoporotic vertebral compressive fracture group, there were 22 patients (26 vertebrae) including 3 males and 19 females aged from 63 to 90 years old with an average of (72.6±7.2) years old. There were 4 patients with two vertebral fractures, 1 vertebra in T9, 2 vertebrae in T10, 3 vertebrae in T11, 9 vertebrae in T12, 6 vertebrae in L1, 3 vertebrae in L2, 2 vertebrae in L3. Operative time, volume of bone cement injection, and vertebral height and changes of Cobb angle before and after operation were observed and compared. Postoperative average recovery rate of vertebral height and correct degree of Cobb angle were caculated and compared, VAS scoring were used to evaluate therapeutic effect.

RESULTSAll operations were completed sucessfully, and pain were relieved at 72 h after operation. All patients were followed up from 6 to 13 months with an average of 10.1 months. Postoperative vertebral height, Cobb angle and VAS score were improved better than that of before operation (P<0.05). Operative time in ordinary group was shorter than severe group, while volume of bone cement injection was more than that of severe group. Average recovery rate of vertebral height and correct degree of Cobb angle in ordinarty group was better than that of in severe group (P<0.05). There was no significant differences between two groups in VAS scores before and after operation (P> 0.05). Three cases (3 vertebrae) ocurred bone cement leakage in ordinarty group, while 5 cases (5 vertebrae) ocurred bone cement leakage in severe group, and there was no meaning between two groups (P>0.05).

CONCLUSIONKyphoplasty could receive satisfied curative effect in treating ordinary and servere patients with osteoporotic vertebral compressive fracture, but recovery of vertebral height and correct degree of Cobb angle in ordinary gourp was better than that of in servere group.
