1.Role and mechanism of XRCC4 in the genesis and development of tumor
International Journal of Surgery 2013;40(10):699-702
DNA double-strand breaks(DSBs) repair protein XRCC4,plays an important role in the genesis and development of tumor,there are many different aspects in the tumor genesis and development.This paper reviews the molecular mechanism of XRCC4 in repairing DSBs,several theories of tumor genesis and development,and the relationship between XRCC4 gene's single nucleotide polymorphisms(SNPs) and tumor.

Objective To investigate the correlation between the disease activity and the serum levels of anti-nuclear autoantibodies against various nuclear components in the patients with systemic lupus erythematosus (SLE). Methods Two hundred and twenty five SLE patients enrolled from 2000 to 2002 were evaluated retrospectively. All patients fulfilled the ACR 1997 diagnostic criteria for SLE. The patients were divided into three groups according to the disease activity: mild group (Group A), moderate group (Group B)and severe group (Group C), as assessed with SLEDAI score. These cases were also divided into 2 groups according to the serum levels of anti-dsDNA antibody. 52 out of 225 patients were followed up further. Results ①There was no correlation between the serum level of anti-dsDNA antibody and SLEDAI score, and between the serum level of ANA and SLEDAI score in 225 patients. ②The serum level of anti-dsDNA antibody in group C was higher than that in group A or group B (P 0.05). Conclusions A positive correlation between the anti-dsDNA antibody and the disease activity was found in the severe group of SLE, but not found in the mild or moderate group. Although the renal damage was more commonly seen in those with higher level of anti-dsDNA antibody, but there is no correlation between the level of anti-dsDNA antibody and the degree of renal lesion.

Gallbladder cancer is a highly malignant tumor of the digestive tract with a poor prognosis. Currently, only radical surgical resection can achieve good results. As an important part of tumor adjuvant treatment and palliative treatment, radiotherapy has been widely used in the treatment of various malignant tumors and achieved certain effect. This article mainly reviews advances of radiotherapy in gallbladder cancer from four aspects: postoperative radiotherapy, preoperative neoadjuvant radiotherapy, intraoperative radiotherapy and palliative radiotherapy for gallbladder cancer.

The completion of human genome project and the progress in medical practice have inevitably lead to the development of precision medicine, which is a medical model that proposes the customization of medical care including medical decisions, practices, and/or medical products with patient's genetic background, environmental factors and life behavior being taken into account. The current work proposed precision stomatology for the first time, and by integrating data reported in recent literature, we described the current practice of precision stomatology in multiple disciplines in modem dentistry. The clinical significance of precision stomatology and its future challenges have also been discussed.

Objective To assess the value of the dynamic enhanced MR (DE-MRI)morphological features in diagnosis of non lac-tation mastitis.Methods We retrospectively studied the breast DE-MRI image data of 1 5 patients with non lactation mastitis con-firmed by pathology were retrospectively studies and the lesion morphological features and distribution were analyzed.Results Amonge 1 5 patients with non lactation mastitis,6 cases were the plasma cell mastitis,5 cases were granulomatous mastitis,2 cases were abscess,and 2 cases were cyst associated with inflammation.The typical features of non lactation mastitis on DE-MRI were fast wash-in,centrifugal enhancement sign,blur boundaries between lesions and normal breast tissue,increasing unilateral vessel sign in diseased breast.Conclusion Breast DE-MRI can show typical morphological features of non lactation mastitis.When dynam-ic information is obtained inconveniently,these are helpful in diagnosing and differential diagnosing non lactation mastitis.

The genetically modified mice , as a helpful model , have been widely used in life scientific research . However, several new issues appeared subsequently with the wide application of the genetically modified mice .Here, we mainly discussed and analyzed the problems in the management and usage of genetically modified mice , which underlies the foundation for establishing management practice of the genetically modified mice .

OBJECTIVE: To discuss the characteristics and regular pattern of the adverse drug reactions(ADR) in our hospital.METHODS: A total of 314 ADR case reports collected by ADR monitoring center in our hospital during 2007 were analyzed statistically.RESULTS: 13 categories(178 kinds) of drugs and 338 cases were involved in the total 314 ADR case reports,mainly anti-infective agents(128 cases,38 kinds) and Chinese drugs preparation(51 cases,20 kinds).The ADR were manifested chiefly as lesions of skin and its appendants(134 cases) followed by gastro-intestinal lesion(56 cases).The patients showed a favorable turn and the death occurred in only 1 case.CONCLUSION: More attention should be paid to the monitoring of rational drug use to avoid or reduce the incidence of ADR.
