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.

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.

Objective To explore an effective method for preventing and treating oral mucosal complications of radiotherapy for head and neck cancer. Methods Fifty head and neck cancer patients who were receiving radiotherapy were enrolled between March, 2008 and March, 2010. These patients were randomly assigned to the treatment group and the control group. During the radiotherapy, patients in the treatment group were given IL-11 in the form of atomization inhalation,whereas patients in the control group were not. Results IL-1 1 was well tolerated by the patients. It significantly decreased the level of oral mucosal complications and pains and improved patients' appetites ( P < 0.05 ). In addition, the duration of pain was significantly ( P <0.05 ) reduced from 4.5 ± 1.3 days ( in control group) to 2.3 ± 1.0 ( in treatment group), and the healing period was also significantly ( P < 0.05) reduced from 7.3 ± 1.5 days ( in control group) to 4.1 ± 1.7 ( in treatment group). Conclusion IL-11 is effective in preventing and treating oral mucosal complications of radiotherapy for head and neck cancer,relieving associated pains, and therefore improving patients' quality of life.

AIM: To quantitatively investigate transforming growth factor-β(TGF-β) and its receptors in normal bulbar conjunctival tissues and pterygium tissues. METHODS: Thirty cases of pterygium patients were randomly selected to undergo surgical resection of pterygium lesion, and the normal margin of bulbar con-junctival tissues were collected as control. Gene expres-sion was detected quantitatively by the method of quantitative real-time PCR (QRT-PCR) analysis. RESULTS: The expression level of TGF-β1 and TGF-β2 was 4.26×10-7±1.45×10-7 and 1.08×10-10±0.68×10-10 in normal bulbar conjunctival tissues, while 10.67×10-7±7.47×10-7 and 8.23×10-11±6.63×10-11 in pterygium tissues. The expression level of TGF-βRⅠand TGF-βRⅡwas 0.003015±0.0036 and 5.33×10-5±5.05×10-5in normal bulbar conjunctival tissues, while 0.000379±0.000281 and 1.002×10-5±9.04×10-6 in pterygium tissues. The expression level of TGF-β1 and TGF-β2 in pterygium was elevated (P<0.01). TGF-β1 expression level in pterygium increase 2.9±2.8 times than in normal conjunctiva. TGF-β2 expression level in pterygium increase 7.5±1.4 times than in normal conjunctiva. The expression level of TGF-βRⅠin pterygium was significantly lower (P<0.05). The expression level of TGF-βRII in pterygium was significantly lower (P<0.01). CONCLUSION: QRT-PCR is an effective method to quantitatively detect gene expression in eye. The upregulation of TGF-β1 and TGF-β2 and downregulation of their receptors expression may play an important role in the pathogenesis of pterygium, which is noteworthy further investigation in diagnosis and treatment of pterygium.real-time PCR; gene expression

Objective To evaluate the pelvic floor function in post-hysterectomy patients. Methods Transperineal pelvic ultrasound was used to observe the pelvic organs in post- hysterectomy patients, and parameters of pelvic floor were measured. Taking the inferior margin of public symphysis as the reference plane,the shape and motion of the proximal urethra and bladder neck were observed at rest and on maximum Valsalva maneuver. Bladder neck-symphyseal distance(BSD) and retrovesical angle were measured. And the bladder neck descent(BND),urethral rotation angle and the rotation angle of the bladder neck were also calculated. Interclass correlation coefficients were calculated to evaluate the consistency of data. Results At rest,the BSD and retrovesical angle were (-2.73±0.37)cm and (119.00±22.40)°, while on maximum Valsalva maneuver was (-0.25±0.67)cm and (114.74±21.50)°,respectively. BND was (2.46±0.59)cm,the urethral rotation angle and the rotation angle of the bladder neck was (70.68±19.91)° and (60.81±17.34) °,respectively. Combined with pelvic ultrasound and clinical manifestations,29 cases of pelvic floor dysfunction after hysterectomy were diagnosed (58.00%, 5 cases of stress urinary incontinence, 8 cases of proctoptoma and 16 cases of bladder prolapse). The consistency was very high in measuring BNS, retrovesical angle at rest and on maximum Valsalva maneuver and BND by different observers. The interclass coefficient was 0.90,0.89,0.91,0.88,0.92,respectively. And the interclass coefficient of urethral rotation angle and the rotation angle of the bladder neck was 0.79, 0.88,respectively. These results showed a good interobserver agreement. Conclusion Transperineal pelvic ultrasound is a simple,reproducible and noninvasive imaging method, which can reveal the position and function of female pelvic organ dynamically and evaluate postoperative pelvic floor function.
