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.

Homeobox(HOX) gene is a kind of regulatory gene,which can regulate the embryonic development and cell differentiation,and participate in the regulation and control of hematopoietic stem/progenitor cell proliferation,differentiation and maturation,etc.Cluster A in HOX gene family is the master gene for proliferation and differentiation of hematopoietic stem/progenitor cells,which has an influence on the number of hematopoietic stem cells and the differentiation of hematopoietic stem cell into erythroid,myeloid,megakaryocytic and lymphatic system,and has a relationship with the generation of leukemia.In this article,study progress of Cluster A in HOX gene family and its relationship with leukemia were briefly stated.

Objective To explore the decision-making process in different types of behavioral activation (BAS) individuals.Methods According to the behavioral inhibition/activation system scales of China,27 low BAS,32 moderate BAS and 26 high BAS individuals were enrolled.Three different kinds of decision tasks (low-risk,high-risk and ambiguity) were programmed with E-Prime,at the same time recorded the scores of earnings,preference selection,decision-making strategy.Results Under low-risk decision,there was significant differences among low,moderate and high BAS groups (low BAS group(54.00±8.15),moderate BAS group(32.63±8.94),high BAS group(27.69±12.12),F=2.240,P＜0.05).There was no significant difference in the three groups on preference selection (F=0.759-2.926,P＞ 0.05).Under low-risk decision,there were significant differences on stay strategy (low BAS＞moderate BAS,high BAS group,F=3.107,P＜0.05) and shift strategy(moderate BAS,high BAS＞low BAS group,F=2.309,P＜0.05).There was no statistically significant difference on quit strategy in the three groups (F=0.629-1.635,P＞0.05).Conclusion Under the low-risk decision-making,low BAS individuals are easier to get more earnings.Moderate and high BAS individuals are easier to change the decision-making strategy than low BAS individuals.

BACKGROUND: The effect of cognitive therapy on psychological stress is not remarkable and optimal. Some psychocatharsis through physical activities cannot be accepted by many clients.OBJECTIVE: To explore an effective method to treat and relieve psychological stress.DESIGN: A controlled (the blank control and the self-control) observation study and single blind trial.SETTING: Department of Preventive Medicine, Medical College of Jinagsu University.PARTICIPANTS: Clients who suffered from emotional suppression or nervous stress would be tested with "psychological stress test". Forty clients, with scores over 5, were selected as the subjects. They were randomly divided into two groups matching of ages and scores: control group (n=20) and experimental group (n=20).METHODS: Clients in the control group were treated with common cognitive therapy by means of talking, and those in the experimental group accepted a sing a song loudly therapy. The song named as Qinghai-Tibet Plateau was selected for the treatment. The clients were requested to sing the song loudly in order to release their stress and vent their repression.The psychologist used the language introduction by background music to make a client under a special kind of psychological situation and emotional state when the music was played for one to two times. Then the psychologist would turn up gradually the volume of sound to the maximum when the music was played for the third time. The volume from the VCD would overwhelm that from the client's voice in order to cover up the singer's shyness. The client sung the song of Qinghai-Tibet Plateau loudly for four to five times. The therapeutic room was required to have a blanch curtain.The sound insulation also was required. The soundscape of the loudspeakers should be wide. The power magnifier should be strong. The loudspeaker should be high fidelity. The questionnaire of psychological stress test was adopted in both groups before and after therapy respectively. It had 30 items for the self-diagnosis of symptoms. The client was diagnosed as a low stress if his or her score reached 5, 11-20 as sever stress, and above 21 as adaptability disorder.MAIN OUTCOME MEASURES: Scores of stress level were observed before and after therapy in both groups.RESULTS: The scores in the control group before and after therapy were approximately the same (15.6±5.3 vs 14.7±4.8, t=1.739, P ＞ 0.05). The scores in the experimental group after therapy was significantly lower than those before therapy (11.6±5.8 vs 15.5±6.1, t=9.863, P ＜ 0.05). After therapy, the scores in the experimental group were significantly lower than those in the control group (11.6±5.8 vs 14.7±4.8, t=4.811, P ＜ 0.05).CONCLUSION: Sing a song loudly is an effective method that is easy to operate in treating psychological stress.

Objective To understand the effect of butylbenzyl phthalate(BBP) on the levels of DNA-protein crosslinks(DPC) in hepatic cells of mice.Methods Twenty-five male Kunming mice were randomly assigned into five groups(n=5).BBP was administered by intraperitoneal injection at doses of 0(control group),125,250,500,1 000 mg/kg respectively for 14 consecutive days.Then the levels of DNA-protein crosslinks were detected.Results DPC coefficient increased with concentration of BBP increasing.Treatments of 500 and 1 000 mg/kg BBP significantly increased the levels of DPC compared with the control group. Conclusion BBP can not cause DPC at low levels(125 mg/kg),but it can cause DPC significantly at high levels(500 and 1000 mg/kg),which may cause serious DNA damages.

Objective To study the clinical and image features of the aortic dissecting aneurysm(AD) combined with aberrant right subclavian arteries(ARSA),and to discuss the feasibility of endovascular repair for such disorder.Methods The clinical and image data of 4 patients,who suffered from AD combined with ARSA and admitted in the authors' service during 2004 to 2007,were retrospectively reviewed.All the 4 cases complained severe aches in their back,and one of them was companied with aches in upper abdomen.CT-exam showed that the first tear(gap) of AD located near or inside ARSA,the truncus aortae narrowed obviously.Four operational prescriptions were performed respectively for the 4 patients depending on the location of gaps and on the distance between the gap and ARSA.Results All the 4 cases received satisfy operation.A slight early leakage occurred in the first case without steal syndrome,and the lower blood pressure was 80 mmHg on right arm;for the second case,no leakage occurred with normal blood presser on both arms;for the third one a slight early leakage was companied with normal blood presser on both arms and for the fourth one a slight early leakage occurred without steal syndrome,and the lower blood presser was 60mmHg on right arm.Conclusion AD combined with ARSA is a rare case in clinic.The modus operandi of endovascular repair should be designed based on the situation of individual case considering the location of the first tear.Once the target area exposed is not wide enough for operation,subclavian artery bypass would be a right way in reduction of leakage complications and in increasing the opportunity for a successful operation.

Objective To observe the Smad5 gene knockout and induced-changes of auditory physiology and cochlea morphology in mouse, to explore whether Smad5 gene is a new gene related to hearing function. Methods Double blind control methods were used to detect the auditory threshold of auditory brainstem responses (ABR) in the mouse of Smad5 (+/+) to Smad5(+/-) and the cochlea morphology (cochlea paraffin-cut section and basal membrane spreading section). The hair cell count was also taken. Results As shown by ABR audiometry, the average hearing of Smad5 (+/-) mouse (aged 24 weeks) is 90.63?17.65 dB (SPL) and that of Smad5(+/+) mouse is 63?19.94 dB(SPL), which are of significant difference (P0.05). Conclusion Smad5(+/-) gene knockout can cause the mouse a auditory threshold decline in moderate or severe extent. Cochlea morphology indicated that hair cells (mainly outer hair cells) in mouse cochlea basal membrane became deficient. A mechanism of Smad5 gene knockout to caused the deafness and the deficiency of hair cells remained to be further studied.

The patient-physician relationship can be understood from the two aspects of patients′ trust and patients′ satisfaction.Compared with patients′ satisfaction,dimensions and attributes of patients′ trust indicate to better match with the measuring capacity of patients.Thus,the evaluation of the quality of medical services based on patients′ trust is justified theoretically.The existing literatures assert that the research on patients′ trust could help understand patient-physician relationship and eventually improve the quality of medical services.The conceptual model in this paper entails the concept,dimensions and attributes of patients′ trust.Also,this paper points out its effect on the measurement of the quality of medical services through the comparison of patients′ trust and patients′ satisfaction.
