Triple negative breast cancer (TNBC)is difficult to benefit from endocrine therapy or tras-tuzumab targeted drug therapy.Biological overexpression of breast cancer susceptibility gene 1,p53 gene,vas-cular endothelial growth factor and microRNA suggests that TNBC is easy to metastasis and recurrence and has a poor prognosis.Exploring the molecular subtypes of TNBC,setting out the treatment plan for subtypes and finding the corresponding monoclonal antibody targets are the research direction of TNBC in the future.

Objective To study the clinical efficacy and the difference of intervention in appendix inflammatory mass by heavenly cool-inducing technique adopted distant and neighboring point selection. Methods Eighty patients of the appendix inflammatory mass with toxic heat syndrome were randomly divided into control group, distant point selection group, neighboring point selection group, and combined group, 20 cases in each group. The control group adopted the conventional western medicine treatment. On the basis of control group, the rest 3 acupuncture groups adopted the heavenly cool-inducing technique for 14 d. The distant point selection group chose Hegu point and Lanwei point;the neighboring point selection group chose Ashi point and Tianshu point (right);the combined group put them together. The longest diameter and three-dimensional volume of inflammatory mass were determined before and after treatment. The serum levels of white blood cells, C-reactive protein were determined at the same time, and then the clinical effective was estimated. Results The longest diameter, three-dimensional volume of inflammatory mass, the serum levels of white blood cells, and C-reactive protein of patients in 4 groups were reduced after treatment. The above indicators in patients of 3 acupuncture groups were lower than the ones in control group, the indicators in combined group were the lowest (P<0.05, P<0.01), and there was no difference between distant and neighboring point selection groups (P>0.05). The invalid number of cases in 3 acupuncture groups were fewer than the one in control group, and the indicators in combined group were fewest (P<0.05, P<0.01), with no difference between distant and neighboring point selection groups (P>0.05). Conclusion There is obvious therapeutic efficacy of heavenly cool-inducing technique to appendix inflammatory mass, while the combination of distant and neighboring point selection is better than the single methods.

Cervical cancer is a common malignancy in women. Surgery and radiotherapy are the main therapeutic approaches. The recurrence rate of cervical cancer is high and the prognosis is relatively poor. Recurrent cervical cancer can be classified into the central pelvic, lateral pelvic and extra-pelvic recurrence. The management of recurrent cervical cancer mainly depends on previous therapeutic approaches and the recurrence site. Surgical resection is the optimal option for patients who have no history of radiotherapy, if feasible, chemoradiotherapy±brachytherapy can be considered. Patients with central pelvic recurrence after radiotherapy are suitable candidates for pelvic exenteration±intraoperative radiotherapy. However, the indications are highly selective, the incidence of postoperative complications is high and the quality of life is poor. Patients with lateral pelvic recurrence after radiotherapy could be treated by re-radiotherapy or chemotherapy. However, the incidence of serious side effects of re-radiotherapy is higher than that of the initial radiotherapy. The indications for stereotactic body radiotherapy are limited and the surgical skill of the surgeons is demanding. In recent years, radiotherapy technology has become more precise. Image-guided brachytherapy, such as high-dose-rate interstitial brachytherapy and radioactive 125I seed implantation, has achieved high efficacy and safety, which may provide new treatment options for recurrent cervical cancer. In this article, research progress on brachytherapy for recurrent cervical cancer was summarized and reviewed.

Objective To investigate the epidemiological situation and the mode of inheritance of ankylosing spondylitis (AS).Methods The AS prevalence investigation was carried out from three different areas in Shandong Province to investigate the incidence of the 80 patients' family members of sick group and calculate the heritability of AS.Results After the investigation and calculation we found the incidence of primary relatives was 7.23％,the heritability was 85.94％,the incidence of secondary relatives was 0.94％ and the heritability was 57.4％,the incidence of thirdly relatives was 0.39％,the heritability is 36.2％,the average heritability among primary,secondary and thirdly was 68.47％ ± 1.64％.Separation ratio was 0.088 9.Conclusion AS is a polygenic disease,its average heritability was 68.47％ ± 1.64％ and separation ratio is 0.088 9.By this research,the incidence risk of AS patients' pedigree offspring can be assessed,then strengthen protective factors to reduce the incidence of the disease to provide the basis for eugenics.

This study was aimed to reveal the relationship of bronchioloalveolar carcinoma (BAC) syndromes and metastasis, in order to provide new scientific basis for syndrome differentiation, treatment and prognostic assessment, which proved the scientificity and feasibility of internal and external inspection. A total of 60 BAC cases were divid-ed into two groups according to the syndrome of deficiency and excess. Another 30 cases of benign pulmonary nod-ules were simultaneous collected in the physical examination as control group. The quality of life (FACT-L) was scored one day before operation for patients in each group. The thoracoscopic technique was used in the biopsy of targeted tissues, in order to reveal indicators related with metastasis. The results showed that the comparison of FACT-L score of patients from two syndromes of BAC and that of the control group indicated that the score of physi-ological state, social/family condition, emotional condition, functional situation, additional situation and total score of the previous one were obviously higher than the latter one (P < 0.01). And the score of patients in the deficiency syndrome group was higher than that of the excess group with statistical significance (P< 0.01). The comparison be-tween the tumor tissues of patients from two syndromes of BAC and the benign pulmonary nodules showed that the VEGF, MMP-2, MMP-9 of the previous one were higher than the latter one (P< 0.01). The comparison between two syndromes showed that all indexes of the deficiency syndrome were higher than the excess syndrome (P < 0.01). It was concluded that syndromes of BAC was related with metastasis.

RNA dot blot hybridization was employed to investigate the alterations in C-myc, C-H-ras transcript levels in bone marrow and peripheral blood cells from 24 patients with acute nonlymphocytic leukemia. 10 cases of normal bone marrow cells were used as control. We found that the positive rates and intensities of expression of C-myc and C-H-ras in acute nonlymphocytic leukemia were hipher than those of normal control. The C-myc and C-H-ras expressed simultaneously in 10 patients. After having been cultured 5 days with RA and low dose Ara-C combined with low dose Harr, the C-myc transcipt level of C-myc in acute nonlymphocytic leukemia was decreased obviously.
