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 explore diagnostic value of basic head-up tilt table test (HUT)and sublingual nitroglycerin head-up tilt table test (SNHUT)on vasovagal syncope (VVS).Methods:A total of 61 patients,who collapsed be-cause of unknown causes and were highly suspected as VVS,were regarded as VVS group,received HUT,and an-other 22 healthy subjects were regarded as healthy control group.Results:Among the 61 cases of VVS group,57 ca-ses were tilt test positive and the positive rate was 93.44%.Among them,there were 16 cases (26.23%)with posi-tive basic HUT and 41 cases (67.21%)with positive SNHUT.The 22 cases in healthy control group also received basic HUT and SNHUT,one case (4.54%)was basic HUT positive and three cases were SNHUT positive.Positive rates of SNHUT was higher than that of HUT,but there was no significant difference in VVS group (χ2 =0.175,P =0.683).Conclusion:HUT is a noninvasive,repeatable method easily accepted by patients for diagnosing VVS currently.It can elevate positive rate of test when combined with SNHUT.

With the rapid development of Picture Achieving and Communication System(PACS), the interpretation of medical images has been changing rapidly from a procedure based on films and light boxes to one based on computers and medical displays. The function parameters of Soft-Copy Reading carriers——medical grayscale display play an important part in radiodiagnosis because they can greatly influence the quality of medical image. It is very easy for quantitative assessment of this influence by using ROC curve theory, and it can direct hospital to select suitable medical display.

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 bioMrieux 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.

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.

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.

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.
