Objective To explore the application value in primary hospitals using conventional ultrasound and ultrasonic elastography in the diagnosis and surgery of breast cancer both in the diagnosis of joint.Methods One hundred and sixteen patients with breast disease confirmed by surgical pathology were studied retrospectively .All the patients were examined by acoustic elastogra-phy and conventional ultrasonography before surgery.Results Pathological results of 116cases were:74 malignanies and 42 benigni-ties.①Preoperative routine ultrasonography in diagnosis of benign breast lesions in 41 cases, 65 cases of malignant lesions.Ultra-sonography showed that benign lesions were round or oval, smooth edge, no obvious signs of malignant microcalcifications, breast cancer spiculation (87.84%, 65/74), intralesional calcification (62.16%, 46/74).With the pathology of routine preoperative ul-trasound diagnosis coincidence rate was 91.38%(106/116).②Ultrasonic elastography in diagnosis of breast benign lesions in 39 ca-ses, 66 cases of malignant lesions, benign lesions of ultrasound elastography score of 1-2 (92.86%, 39/42); malignant lesions of ultrasound elastography score of 3-5 (89.19%, 66/74);and the pathology of preoperative ultrasound elastography diagnosis coinci-dence rate was 90.51% (105/116).③Preoperative ultrasound elastography and conventional ultrasound diagnosis of 42 cases of be-nign lesions, 68 cases of malignant lesions, and pathological diagnosis coincidence rate was 94.82% (110/116).Conclusion Ul-trasound elastography and conventional ultrasound examination can improve the resection of benign and malignant breast lesions diag-nosis in primary hospital diagnosis, as an effective method for the detection of breast cancer before operation .

Objective To observe the relationship between homocysteine (Hcy),C-reactive protein (CRP) and type 2 diabetes peripheral vascular disease (PVD).Methods Fifty-eight patients with type 2 diabetes according to the condition of PVD were divided into simple type 2 diabetes mellitus group (DM group,30 cases) and PVD group (28 cases).Twenty-five healthy people were chosen at the same period as control group.The fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),total cholesterol(TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C),Hcy and CRP levels were detected among 3 groups,and the body mass index (BMI),ankle brachial index(ABI) was calculated.Results The BMI,TG,TC and HDL-C levels among 3 groups had no statistical significance (P ＞0.05).The FBG,HbA1c and LDL-C in DM group and PVD group were significantly higher than those in control group [(7.54 ± 1.25),(8.12 ± 1.57) mmol/L vs.(4.68 ±0.54)mmol/L; (6.92 ± 0.89)％,(7.54 ± 0.97)％ vs.(4.80 ± 0.54)％ ; (3.79 ± 0.73),(4.41 ± 0.93) mmol/L vs.(2.68 ± 0.54) mmol/L],and the difference was statistically significant (P ＜ 0.05).But the difference between PVD group and DM group had no statistical significance (P ＞ 0.05).Hcy and CRP in DM group and PVD group were higher than those in control group [(10.26 ± 3.62),(19.83 ± 5.54) μ mol/L vs.(8.92 ± 2.41)μ mol/L; (4.12 ±0.57),(5.47 ±0.85) mg/L vs.(2.73 ±0.54) mg/L],ABI was lower than that in control group(0.92 ± 0.18,0.81 ± 0.16 vs.1.02 ± 0.23),and the difference was statistically significant (P ＜ 0.05);Hcy,CRP in PVD group were obviously higher than those in DM group,ABI was lower than that in DM group,and the differences were statistically significant (P＜ 0.05).Spearman analysis showed that Hcy was negatively correlated with ABI (r =-0.635,P ＜ 0.05),CRP was negatively correlated with ABI (r =-0.529,P ＜ 0.05),and Hcy was positively correlated with CRP (r =0.528,P ＜ 0.05).The partial correlation analysis results showed that Hcy and ABI still showed a negative correlation (r =-0.315,P ＜ 0.05),CRP and ABI still showed a negative correlation (r =-0.243,P ＜ 0.05).Conclusion Hcy and CRP participating in the occurrence and development of type 2 diabetes PVD,can be used as a predictor of type 2 diabetes PVD.

BACKGROUND:Alpha-calcium sulfate hemiydrate/biphasic bioceramics (α-CSH/BCP) as a bone repair material has been widely used in the clinic, but there are stil some deficiencies. OBJECTIVE:To observe the effect of α-CSH/BCP on the repair of bone defects of the radius in rabbits. METHODS:The unilateral radius of 18 adult New Zealand white rabbits was selected to establish bone defect models, and then these rabbit models were randomized into three groups that were treated with α-CSH,α-CSH/BCP, BCP materials, respectively. At 4, 8, 12 weeks after implantation, bone samples were taken for gross and X-ray observations. RESULTS AND CONCLUSION: (1) Gross observation: At 12 weeks of implantation, the bone defect was completely repaired in the α-CSH/BCP group, and the defected radius recovered basicaly; in the α-CSH group, bone defects were visible; and in the BCP group, there was stil some material for filing and coverage. (2) X-ray observation: In the α-CSH group, the degradation of implanted materials was faster than new bone formation, and bone defects were visible; in the α-CSH/BCP group, bone defects were healed, cortical bone remodeling was good, and the bone marrow cavity was re-canalized; in the BCP group, the implanted materials were stil visible, and bone defects were not repaired. These findings indicate that the α-CSH/BCP bone repair material can significantly promote the repair of bone defects of rabbit radius, with a better repair effect than α-CSH or BCP alone.

OBJECTIVE:To systematically review the efficacy and safety of escitalopram versus paroxetine in treatment of se-nile patients with depression in China,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from CJFD,VIP,Wanfang database,CBM database,randomized controlled trials(RCT)of escitalopram(test group)versus paroxetine (control group) in the treatment of senile patients with depression in China were collected. After quality evaluation and data ex-tract,Meta-analysis was performed by using Rev Man 4.2 statistics software. RESULTS:A total of 14 RCT were included,involv-ing 1 148 patients. Results of Meta-analysis showed there was no significant difference in the cure rate[OR=1.20,95%CI(0.93, 1.53),P=0.16],significant effective rate[OR=1.23,95%CI(0.94,1.61),P=0.12],the incidences of headache[OR=0.81,95%CI (0.40,1.65),P>0.05],the incidences of tachycardia [OR=0.37,95%CI(0.09,1.52),P>0.05],the incidences of insomnia [OR=1.26,95%CI(0.33,4.82),P>0.05] and the incidences of tremor [OR=0.31,95%CI(0.04,2.24),P>0.05] between test group and control group;the incidences of xerostomia[OR=0.50,95%CI(0.31,0.80),P<0.05],the incidences of nausea[OR=0.49,95%CI (0.36,0.66),P<0.05],the incidences of sweating [OR=0.31,95%CI(0.15,0.62),P<0.05],the incidences of constipation[OR=0.31,95%CI(0.15,0.64),P<0.05],the incidences of dizziness[OR=0.38,95%CI(0.20,0.72),P<0.05] and the incidences of an-orexia[OR=0.45,95%CI(0.21,0.99),P<0.05] in test group were significantly lower than control group,there were significant dif-ferences in 2 groups. CONCLUSIONS:The efficacy of escitalopram and paroxetine is similar in the treatment of senile patients with depression,however,the safety of escitalopram is better than paroxetine. Due to the limit of methodological quality and sam-ple size,it remains to be further verified with more rigorously designed and long-term follow-up of large-scale RCT.

Objective: To study the phenylpropanoid constituents from the whole plants of Pedicularis dichotoma and the anti-fatigue activities in vivo. Methods: The n-BuOH fraction of 95% ethanol extract from P. dichotoma was separated and purified by silica gel, re-phase and Sephadex LH-20 column chromatography. The structures of the compounds were identified by physicochemical properties and various spectroscopic methods. The compounds were tested on anti-fatigue activity using mice in swimming model. Results: Twelve phenylpropanoid compounds were isolated and purified. Their structures were identified as verbascoside (1), isoverbascoside (2), leucoseptoside A (3), jionoside D (4), martynoside (5), isomartynoside (6), cis-martynoside (7), citrusin C (8), robustaside B (9), darendoside B (10), zizybeoside I (11), and salidroside (12). Verbascoside could obviously prolong the swimming time of mice. Conclusion: Compounds 1-12 are obtained from the plant for the first time, and compound 11 is reported from the plants of Pedicularis Linn. for the first time. Phenylpropanoids show obvious anti-fatigue activities.

0.05;AGC R 1 to R 2 P 0.05.The invasive depth of the lesion corresponded to the degree of lymph node metastases.No relation was found between tumor size and the survival rate.The prognosis of type Ⅲ EGC and AGC with infiltration was poor.Conclusions: Biological behavior of gastric cancer can be used as a guide to operation type.We proposed that EGC should undergo subtotal gastrectomy plus R 1 or selective R 2 ,and AGC should undergo subtotal gastrectomy or near total gastrectomy plus R 2 or selective R 3 ,with a margin of at least 5 cm from the tumor.

OBJECTIVE:To optimize kind of safe and effective iodophor thinner.METHODS:Iodophor solutions in several different solvents were made and diluted 5,10 and 20 times,respectively.Then their microbicidal potentials on 3 standard strains were monitored.RESULTS:The standard strains were all killed within 5 min by iodophor solution in normal sodium or by low multiple diluted iodophor solution in distilled water;however,there were a few Escherichia coli and Pseudomonas aeruginosa still alive within 5 min in high multiple diluted iodophor solution in distilled water.Iodophor solution in tap water failed to kill all the standard strains,especially the Pseudomonas aeruginosa.CONCLUSION:Normal saline solution and distilled water have been proved to be the ideal iodophor thinners.

Objective To observe the incidence and the rate of embolism in patients undergoing hysteroscopy procedures by using the transesophageal echocardiography (TEE), as well as the changes of respiratoric and haemodynamic variables. Methods Fourty ASA Ⅰ~Ⅱ patients undergoing hysteroscopy procedures under general anesthesia received intraoperative TEE monitoring. The systolic pulmonary artery pressure, the incidence of the venous gas embolism (VGE) and the eegmental wall motion abnormality (SWMAs) were observed. Results In the 40 patients, 38 patients received intravenous anesthesia hysteroscopic surgery, with the intraoperative TEE to monitor the intracardiac VGE. The degree of gas embolism was related with the perfusion and the usage of monopolar or bipolar diathermia (P<0.05). The systolic pulmonary artery pressure promoted and SWMAs were also observed. Conclusions The continue TEE monitor during hysteroscopy could detect the intracardiac gas embolism in time , contributing to early diagnosis and avoiding the occurrence of malignant arrhythmias or myocardial ischemic events.
