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.

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 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.

Massage prescriptions for treating infantile anorexia in Chinese Academic Journal Full-Text Database (CNKI, 1979-2012), Chinese Scientific and Technological Journal Full-Text Database (VIP, 1989-2012) and Wanfang Database (1990-2012) were collected. By using Chinese Medicine Inheritance Auxiliary Platform (Version 2.0) Software, 286 massage prescriptions for treatment of infantile anorexia were screened involved 76 acupoints, 20 commonly used acupoints, and 57 core acupoint combinations. Infantile Tuina specific points were used as main acupoints in massage therapy for infantile anorexia, and core acupoints covered Jizhu, Pi meridian, abdomen, Nei-Bagua, Zusanli (ST36), and Ban-men.

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 observe the effect of Pingchuanlingchongji (PCL) on the auricular microcirculation of mice and to investigate the effect mechanism of the treatment for asthma. Methods 50 mice were randomly divided into five groups, group 1 and group 2 were given 0.9% NS (25 mL/kg) as control group; group 3 was given aspirin (0.25 g/kg), 4 group was given low-dose (1.1 g/kg) PCL, group 5 was given high-dose (2.2 g/kg) PCL. Last for seven days. We injected Posterior Pituitary Injection (0.5 U/mL) on the rear vein of 2-5 group mices after the last time of given druy. The diameter of micro-artery in mice auricular, the diameter of micro-vein and blood flow speed were observed. Results As compared with contral group, PCL could expand significantly the diameter of micro-artery and the diameter of micro-vein in mice auricular (P

Objective To evaluate the effect of -477C/T single nucleotide polymorphism (SNP) in promoter region of ABCA1 gene on plasma levels of high density lipoprotein cholesterol (HDL-C) and coronary artery disease (CAD). Methods -477C/T genotypes in promoter region of ABCA1 gene were assessed in 96 CAD patients and 100 healthy individuals with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and distribution of the -477C/T genotypes was compared between CAD group and healthy group, and also between patients with different CAD clinical manifestations. The clinical indexes associated with CAD were also compared among the three genotypes. Results The distributive frequency of CC, CT, or TT genotype of CAD group and healthy group was different from one another, and the proportion of the TT genotype or the T allele was obviously higher in CAD group than in healthy group (P

0.05). Conclusion The genotypes of ABCA1 R1587K polymorphism were associated closely with the plasma levels of HDL-C. The HDL-C levels of K allele carriers were remarkably lower. However, there was no significant association of the ABCA1 R1587K polymorphism and the susceptibility to CAD.
