1.Will Chinese ovarian cancer patients benefit from knowing the BRCA2 mutation status?
Chinese Journal of Cancer 2012;31(1):1-4
In Western countries, the mutation status of the BRCA1 and BRCA2 genes is commonly determined for genetic counseling among members of families with a history of breast or ovarian cancer, especially for women of the Ashkenazi Jewish ethnicity. Recent studies in the Cancer Genome Atlas project have demonstrated that BRCA2 mutation carriers are more responsive to platinum-based chemotherapy among high-grade serous ovarian cancer patients. Thus, in Western countries, the mutation status of BRCA1 and BRCA2 is recognized to have an important value with which to assess cancer risk and therapeutic response. However, very limited studies of BRCA1 and BRCA2 mutations and their implications for counseling and therapeutic prediction have been conducted in China. Therefore, a potentially important genetic test that is technically simple has not benefited Chinese women with an increased risk of breast or ovarian cancer. This article summarizes the current progress in the study of BRCA1/2 mutation in China and recommends an increased effort in applying advances in genetic testing to the clinical management of Chinese patients with ovarian cancer.

Objective To observe the clinical features of pulmonary infections secondary to lung tuberculosis and explore the nursing care strategy in this condition.Methods Retrospective analysis on in patients of lung tuberculosis with secondary pulmonary infections from Sep 2000 to Aug 2002.Results Of 53 tuberculostic patients who were suffered from lung infection after hospitalization,majority were secondary tuberculosis including chronic fibrosis with cavity information in 21 cases and exudative in 17 cases while other typies like miliaris disseminata in 14 cases.Total mortality was 11.3%.Conclusion Intensive and specific nursing care could reduce the prevalence of nonsocasimal infection in tuberculostic in-patients and improve the outcome.

Objective To explore the therapeutic effect of Xiefu Zhuyu decoction joint brain protein hydrolysate injection in the treatment of patients with traumatic brain injury and its effect on cerebrospinal fluid of endothelin-1 ( ET-1 ) .Methods 102 cases of patients with craniocerebral injury were divided into control group (n=51) and experimental group (n=51),the control group were treated with brain protein hydrolyzate injection, the experimental group based on the control group were treated with Xuefu Zhuyu decoction, the curative effect, ET-1, inflammatory factor, protein, blood rheology, S-100β, neuron specific enolase (NSE), National Institutes of Health Stroke Scale (NIHSS) and complications of two groups were compared.Results The total effective rate of experimental group was higher than the control group (94.11% vs.78.43%), the difference was statistically significant (P<0.05).The ET-1 of experimental group was lower than the control group[(32.45 ±4.05) ng/L vs.(28.11 ±3.50) ng/L] (P<0.05).The inflammatory factor, protein, blood rheology, NSE, S-100βof experimental group were better than those of control group (P<0.05). The NIHSS of experimental group was lower than that of the control group ( P <0.05 ) .The complication rate had no difference between two groups. Conclusion The clinical curative effect of Xiefu Zhuyu decoction joint brain protein hydrolysate injection in the treatment of traumatic brain injury , can reduce cerebrospinal fluid levels of ET-1 and can improve inflammatory factors, proteins and hemorheology.

AIM: To observe the differences in central cornea thickness, anterior chamber depth, corneal anterior curvature and corneal posterior curvature between the Uygur and the Han nationality college emmetropia students, and analyze the relationship of corneal thickness and corneal curvature.
METHODS: More than 500 students in grade one in Xinjiang Medical University were underwent screening, 56 emmetropia eyes in Han nationality students and 51 in Uygur students were selected. Sirius corneal topography was applied to the measurement.
RESULTS: Uygur and the Han nationality college emmetropia students central cornea thickness ( Uygur:0.53±0. 03mm, Han: 0. 54±0. 03mm), anterior chamber depth ( Uygur: 2. 91±0. 26mm, Han: 3. 14±0. 25mm), corneal posterior curvature K2 ( Uygur: -6. 30±0. 23D, Han: -6. 38±0. 28D) had significant difference (P<0. 05). Corneal anterior curvature ( K1, K2 ) before and corneal posterior curvature K1 there was no significant difference (P>0. 05). Han had no significant relationship in corneal thickness and corneal anterior curvature ( r<0 ) , or in corneal posterior curvature ( r < 1 ) . Uygur has no significant relationship in corneal thickness and corneal anterior curvature (r<0), or in corneal posterior curvature (r<1).
CONCLUSION: There are significant differences between the Uygur and the Han nationality college emmetropia students in cornea thickness, anterior chamber depth and corneal posterior curvature K2. There is no significant relationship between corneal thickness and corneal curvature in Uygur and the Han nationality college students.

Electrophysiology examination is an important technique in studying amblyopia, which mainly includes electrooculography( EOG), electroretinography ( ERG), visual evoked potential( VEP). This study does not only summarizes the definition, the mechanisms and the meaning of these indexes in the relevant research progress in recent years, but also makes a comment on the controversies among the relevant research conclusions.

Objective To investigate the gene variation and the dependability and to evaluate the possible tumor suppressor genes on chromosome 9 in the development and progression of EC. Methods LOH was detected in normal esophageal mucosa, high-grade squamous dysplasia and esophageal squamous cell carcinoma by microdissection, polymerase chain reaction, denaturing polyacrylamide gel eleetrophoresis and silver nitrate staining technology. The changes of LOH at six microsatellite markers and the relationship between LOH rate were analyzed. Results In the informative cases, total frequency of LOH was 17.2 % in high-grade squamous dysplasia and 24.9 % in esophageal squamous cell carcinoma. In high grade squamous dysplasia and squamous cell carcinoma, LOH was detected at marker D9S162 (20.8 %, 36.7 %), D9S171 (33.3 %, 36 %), D9S753(34.8 %, 46.2 %), D9S1748(4.2 %, 13.8 %), D9S242(14.3 %, 21.2 %), D9S43(0, 0). The frequency of LOH showed significant difference among the six microsatellite markers (X2=17.26, P< 0.005; X2=22.66,P<0.005). Conclusion The progression from normal squamous epithelium to high-grade Squamous dysplasia and subsequently to squamous cell carcinoma of the esophagus is associated with accumulation of chromosomal change. The situs of D9S171, D9S162, D9S242, D9S753 exist higher LOH and all exceed 20 %. Possible tumor suppressor genes at or near D9S171, D9S162, D9S242, D9S753 may be related to the progression of esophageal squamous cell carcinoma.

Purpose:To study the incidence of pneumonia, pathogenic bacteria and prognosis in patients with neoplasm after chemotherapy.Methods:Sputum culture was made by routine method. Then,to determine the kinds of bacteria bioMrieux ATB expression was used, and general drug-sensitivity test was done by Kirby-Bautr method.Results:Fever occured in 27.3% patients after chemotherapy, while pneumonia in 11.3% patients. 13 kinds of bacteria, 72 strains of bacteria and 2 kinds of fungi were found in 68 positive culture samples. The infection rates were 76.5% in infection of single bacteoia,23.5% in infection of two kinds of bacteria and 22.1% in bacteria with fungi. The infection rate of gram-negative bacteria is much higher than that of gram-positive ones (P<0.01).Conclusions:The incidence of pneumonia in the hospital is higher in patients with neoplasm after chemotherapy. Most pathogenic bacteria are gram-negative and sensitive to aminoglycosides, piperacillin and norfloxacin.
