Breast cancer is the most common disease in women worldwide, which not only threatened the women’s survival time, but also inlfuenced their quality of life as well. Within this challenge, it’s important to optimize the current multidisciplinary treatment stratagem for breast cancer. Radiotherapy is one of the most important treatment modality for patients with breast cancer, with the trend to shrink the irradiated volume and shorten the total fraction times in recent years. Intraoperative radiation therapy (IORT) as a fast and convenient procedure has the ability to deliver a high, single-fraction radiation dose to tumor beds with minimal exposure of surrounding tissues (lung, heart, etc.), which could be displaced or shielded right after the tumor removal during the surgical procedure. Right now, IORT has been either integrated as a boost technique in multimodal approaches using postoperative EBRT in the treatment of early breast cancer patients undergoing breast conservation surgery or used as a single dose accelerated partial breast irradiation technique for these patients. This review discussed the rationale of IORT, the beneifts and limitations of IORT, the indication and the clinical results of this procedure, including treatment related side-effects as well in order to provide the preliminary evidence based approach for early breast cancer patients.

Objective To map the complete methylation status of the hMLH1 promoter in sporadic colorectal carcinoma and analyze the relationship between MVPs (methylation variable positions) of hMLH1 promoter and the expression of hMLH1. Methods Methylation status of hMLH1 promoter was measured by bisulfite sequencing. hMLH1 protein expression was detected by immunohistochemistry. Results Out of the 30 sporadic colorectal carcinoma specimens, the hypermethylation of CGIs (CpG islands) 1 was in 6 and that of CGIs 2 in 4. The hMLH1 protein was detected in 15 specimens. Chi square test showed the methylation of CGIs 1 was closely related to loss of hMLH1 protein expression (P0.05). Conclusion In CGIs 1, CpG positions from 1 to 28 are the critical region that could influence the expression of hMLH1.

Trans-cinnamaldehyde, the main component of volatile oil from cassia twig or Cinnamomum cassia, which is a traditional Chinese herbal medicine. Trans-cinnamaldehyde is a kind olefine aldehyde of organic compounds and has many pharmacological properties, such as anti-inflammatory, anti-tumor, anti-bacterial, antidiabetic, anti-obesity, and neuroprotection etc. The compound has preventive and therapeutic effects on the nervous system, cardiovascular, cancer, diabetes and other diseases. Trans-cinnamaldehyde, as a preventive care of nature medicine, has great clinical and market potential. This paper gives a review about the pharmacological effects and mechanism of trans-cinnamaldehyde researched in the latest five years. We hope to provide some basic information for further research on trans-cinnamaldehyde.

ObjectiveTo evaluate the clinical value of Young's modulus by supersonic shear wave elastography (SWE) in differential diagnosis of thyroid solid nod1ules.MethodsEighty-three patients with 113 solid nodules were examined by SWE.All the nodules were confirmed by pathology.According to Young's modulus,a receiver operating characteristic (ROC) curve was drawn,and it used to identify the value of optimal operating point for differential diagnosis of thyroid nodules.Results ① The mean of Young's modulus of benign nodules was (23.57 ± 9.35)kPa,which was significantly different from the valve of malignant nodules (43.73 ± 19.82) kPa ( t =6.31,P =0.00).(②) It showed that the optimal operating point of ROC curve as 27.49,with high sensitivity(93.2％),specificity(81.2％) and accuracy (85.8％).The area under ROC curve was 0.91.Conclusions SWE is a newly quantitative technique of ultrasonography,which is helpful to identify and distinguish in the differential diagnosis of thyroid nodules.

Objective To observe the anti‐metastatic effect and mechanism of baicalin on the growth of HeLa cells was measured by MTT assay ,and cell migration baicalin on human cervical cancer HeLa cells .Methods The effects of baicalin on the proliferation and invasion of HeLa cells were analyzed by MTT method and Transwell assay .Moreover ,Real‐time PCR was used for investigating the expressions of MMP‐2 and MMP‐9 at the RNA level .Western blot was used for investigating the expressions of MMP‐2 ,MMP‐9 ,P38 and p‐P38 at the protein level .Results Baicalin could significantly inhibit the proliferation of HeLa cells in the dose‐dependent manner at the concentration above 60 μg/mL . Anti‐metastatic signaling induced by baicalin was characterized by down‐regulating the RNA and protein expressions of MMP‐2 and MMP‐9 ,and down‐regulating the phosphorylation level of P38 . Pre‐treatment of P38 signal pathway inhibitor could enhance the inhibitory effect of baicalin on the expressions of MMP‐2 and MMP‐9 .Conclusion These results indicate that baicalin‐induced anti‐metastatic effect involves the inhibition of MMP‐2 and MMP‐9 in HeLa cells through P38 signal pathway .

Objective Objective To investigate the clinical application of high-dose-rate(HDR)endobronchial brachytherapy for the treatment of primary lung cancer with atelectasis. Methods A total of 142 cases of lung cancer with atelectasis treated with HDR endobronchial brachytherapy and 71 cases(contr01)treated with extemal irradiation only at onr center of cancer were comparatively studied.1n the treatment group,with the aid of bmnchoscope,brachytherapy was applied 2 or 3 times at the dose of 8 Gy each time to a tissue depth of 1 to 1.5 cm.Cases in the contmlgroup,treated with external irradiation,received 60-70 Gy in total.Results Complete recruitment of atelectasis was observed in 80.28%cases of the treatment group and 64.79%in the control,T11ere Was significant difference between the two groups.Survival rates after 1,2 and 3 years in cases with complete remission of atelectasis in treatment group were 60.68%,44.44%and 23.93%,but 36.00%,28.00%and 16.00%in cases with no remission of atelectasis.Significant difference of one-year survival Was found between the two groups(P

Objective:To investigate the effects of propofol on cerebrospinal fluid pressure(CSFP),mean arterial pressure(MAP),cerebral perfusion pressure(CPP) and heart rate(HR)during induction of anesthesia in patients underwent intracranial operation. Methods: In 20 patients scheduled for elective craniotomy, an epidural catheter was placed into subarachanoid. Fentanyl(2 ?g/kg), intravenousl Midazolam (0.04~0.05mg/kg) and propofol (2mg/kg) were administered respectively prior to induction of anesthesia. CSFP,MAP,CPP and HR were monitored at 2min,5min after propofol administration and 2,5,10min after another supplementary dose of propofol 1mg/kg addendum during endotracheal intubation. Results: Compared with the preanesthetic baseline values, CSFP, CPP, and MAP all decreased significantly during induction(P

Objective To investigate the correlation between helicobacter pylori infection and pathological characteristics of gastric mucosal in the elderly.Methods Retrospective analysis was conducted in 278 patients with benign upper gastrointestinal disease from January 2014 to June 2014.The patients were examined by endoscopy and 13C-UBT,and divided into elderly group (aged 60 years and over,n=111) and non-elderly group (aged＜60 years,n=167).The relationships between Hp infection and pathological changes in gastric mucosal tissue (severe chronic inflammation,neutrophil infiltration,lymph follicles,gastric gland atrophy,intestinal metaplasia) were analyzed.Results There was no significant difference in helicobacter pylori infection rate between the elderly group and non-elderly group [27.0％ (30/111) vs.36.5％ (61/167),P＞0.05].The rate of gastric gland atrophy was higher in elderly group than in non-elderly group [13.5％ (15/111) vs.6.0％ (10/167),P=0.028].The rates of severe chronic inflammation,neutrophil infiltration,lymph follicles,gland atrophy and intestinal metaplasia were 73.6％,70.3％,14.3％,18.7％,29.7％ in patients with helicobacter pylori infection,which were higher than those in patients without helicobacter pylori infection (19.8％,3.2％,0.5％,4.3％,8.6％,respectively,all P=0.000).Removing the factor of Hp infection,the rates of glands atrophy and intestinal metaplasia were higher in elderly group than in non-elderly group (8.6％ vs.0.9％,43.3％ vs.23.0％,P=0.013 and 0.045).Conclusions Helicobacter pylori infection correlates with severe chronic gastric mucosal inflammation,neutrophil infiltration,lymph follicles formation.Gland atrophy and intestinal metaplasia are related to the Hp infection,and age is also their influencing factor.
