Objective To investigate the clinical application value of ultrasound-guided catheter drainage and vacuum-assisted Mammotome system in the treatment of lactational breast abscess. Methods The clinical data of 46 patients with lactational breast abscesses were analyzed retrospectively. All patients were divided into control group (28 patients) and treatment group (18 patients). Homemade irrigation and drainage tube was used in control group,and vacuum-assisted Mammotome system was used in treatment group. The curative effect of 2 groups was compared. Results All patients were cured. The mean healing time in treatment group was (9.5 ± 1.3) d,in control group was (12.5 ± 2.2) d, and there was significant difference (P < 0.01). The rate of breast-feeding in control group was 57.1% (16/28), in treatment group was 13/18,and there was no significant difference (χ2=1.069, P>0.05). All patients recovered well without recurrence. Conclusions Ultrasound-guided catheter drainage should be employed as first line treatment of breast abscess with diameter greater than the 3 cm. If patient′s economic conditions are good and have high requirement on the beauty outcome, vacuum-assisted Mammotome system can be applied as treatment option.

In order to obersve the effect of dexamethasone on the secretion of apolipoproteins A Ⅰ, A Ⅱ, C Ⅲ, B100 and E by cultured HepG2 cells.The apolipoprotiens contents in culture media were measured by radioimmuodiffusion assay (RID) kits developed by authors' research unit. 20-fold lyophilizely condensed culture media were used for the assays. The results showed that dexamethasone can increase the secretion of apoC and E, and inhibit the secretion of apoAⅡ , B100 and CⅢ; and the effect of dexamethasone were strengthened in a dose-dependent manner. When the concentration of dexamethasone was 5.5 × 10-5mol/L in the culture media, the secretion of apolipoprotein A Ⅰ and E increased 36.6% and 49.4%(P ＜ 0.01) respectively, while the secretion of apo AⅡ , B100 and CⅢ decreased 38.9%、 31.9% and 29.8% (P＜0.01) respectively.

The clinical practice of medical students relates to many complicated interests. There exist insufficiency and irregularity in present law,so perfecting the law in medicine stu-dents’clinical practice is necessary. The lawmaking should insist on the balance in every main body’s right,obligation and responsibility,justice in restriction,acknowledgement and agreement and the principle of multi-factors and level partition.

0.05).Conclusion There is no significant difference of short-term effect between the two groups in treating advanced NSCLC,and the method has mild digestive reactions and nephrotoxicity.

The research outputs from 2010 to 2014 in clinical medicine of the top 10 universities announced by the Academic Degrees Center under Education Ministry of China in 2012 were analyzed and assessed according to the index system for assessment of research outputs in clinical medicine we established on the basis of bibliometrics.

Objective: To explore the correlation between serum level of high molecular weight adiponectin (HMW-ADPN) and arteriosclerosis. Methods: Clinical data of 87 middle-aged and aged people living in home, who underwent health examinations in Xiangya second hospital from Jan 2011 to Dec 2011, were collected. According to carotid-femoral pulse wave velocity (cf-PWV) = 9 m/s, they were divided into group A (cf-PWV<9 m/s, n=21) and group B (cf-PWV≥9 m/s, n=66). Blood pressure, blood lipid, blood glucose etc. were measured and compared between two groups. Results: Compared with group A, there were significant rise in blood pressure, levels of low density lipoprotein cholesterol, triglyceride and total cholesterol, and significant reduction in levels of high density lipoprotein cholesterol (HDL-C), serum total ADPN and HMW-ADPN in group B, P<0.05 or <0.01. Multiple regression analysis indicated that serum HMW-ADPN (B= - 4.469，P=0.011), total ADPN ((B= - 3.965，P=0.012), HDL-C（B= - 2.077，P=0.015) and systolic blood pressure levels (B= 0.045，P=0.045) were independent predictors of cf-PWV. Conclusion: Serum high molecular weight adiponectin and total adiponectin levels may be protective factors against arteriosclerosis. Its role in predicting occurrence and development of arteriosclerosis is worthy of further study.

Objective:This study was conducted to investigate Epstein-Barr virus (EBV) infection in gastric cancer in Wuwei ar-ea of Gansu province (China) and the roles of miR-101, EZH2, and COX-2 in EBV-associated gastric carcinomas (EBVaGC). Meth-ods:Tissue microarray technique, immunohistochemistry, and in situ hybridization were performed to detect the expression of EBV-en-coded small RNAs (EBERs), miR-101, EZH2, and COX-2, in gastric cancer tissues (n=120) and the corresponding adjacent tissues (n=120). Results:The positive rate of EBV was 10.0% in 120 cases of gastric cancer tissues. EBVaGC was not significantly associated with lymph node metastasis and developed most often in the cardia and body (P<0.05). The differences in the positive rates of miR-101, EZH2, and COX-2 in 120 cases of gastric cancer tissues and corresponding adjacent tissues were significant (P<0.05). The differences in the positive rates of miR-101, EZH2, and COX-2 in 12 cases of EBVaGC and in 108 cases of EBV-negative gastric can-cer (EBVnGC) tissues were significant (P<0.05). The infection of EBV in gastric cancer tissues was positively related to miR-101 ex-pression. By contrast, miR-101 expression was negatively related to lymph node metastasis and expression of COX-2 and EZH2 in EB-VaGC tissues (P<0.05). Conclusion:EBV infection was related to gastric cancer in Wuwei area of Gansu province. EBVaGC and EB-VnGC have significant differences in lymph node metastasis and in the location of cancer. MiR-101, EZH2, and COX-2 were related to the development of EBVaGC.

Objective To evaluate the effect and safety of combined treatment by laparoscopic cholecystectomy and subsequent ablation in patients with HCC adjacent to the gallbladder. Methods From June 2005 to June 2009,13 patients with HCC nodules( less than 3 cm) adjacent to the gallbladder were treated by ablation after laparoscopic cholecystectomy. The rate of complete necrosis as well as postoperative complications were also analyzed. Results All the patients showed complete necrosis of their tumor lesions after treatment by ablation subsequence of laparoscopic cholecystectomy. During the follow-up period( nearly 2 years), recurrent nodules appeared in other subsegments but not at the original site treated by ablation. Of note, no fatal complications were observed in all the ablation treated patients. Conclusion Combined treatment by laparoscopic cholecystectomy and subsequent PMCT was an effective and safe method for patients with small HCC which was adjacent to gallhladder.

Physician-patient trust is the basis of informed consent,and the informed consent institution is supposed to strengthen the trust.However,it affects trust in an opposite way in practice. This research aimed to analyze the relationship between informed consent and physician-patient trust,and provide with the advice,recommending on such rebuilding.

The study found that the physician-patient trust crisis results from overreliance on technology trust instead of interpersonal trust and institutional trust. The alleged “Paternalistic government innovation”in healthcare service has caused wastes of healthcare resources and gap below public expectancy due to its incompetence in resolving social problems,further eroding institutional legality and intensifying such crisis.This research aimed to identify government accountabilities in building such trust from three aspects.
