With the application of high throughput sequencing and other technologies, in recent years people have found that bacteria are not only the causative factors of common breast diseases such as mastitis, but also may be involved in the occurrence and development of breast cancer. There are unique bacterial communities in the internal tissues of the breast, and their existence may be related to the incidence of breast cancer. Recent studies have found that intestinal flora may also affect the incidence of breast cancer by regulating estrogen and other pathways. Further exploration of the influence of bacteria on breast cancer will provide new ideas for diagnosis and treatment of breast cancer.

Objective To analyse the quality of life in patients with severe acute respiratory syndrome (SARS) for 10 years. Methods Twenty-five SARS patients were collected as SARS group and 25 healthy persons were used as control group. There were no significant differences in general clinical data between two groups. The quality of life of the respondents was evaluated by the MOS item short form health survey (SF-36) including physiological function, physical pain, general health condition, energy, social function, emotional function and mental health. The pulmonary function indicators including forced vital capacity (FVC), one second forced expiratory volume (FEV1), one second rate (FEV1/FVC), total lung capacity (TLC), residual volume (RV), corrected breath diffusing capacity (TLCOc SB) and corrected dispersion rate TLCOc/VA were also compared between two groups. The correlation between each dimension score of pulmonary function indexes and quality of life were analyzed in SARS group. Data of hip and femoral head necrosis were detected by MRI scan in SARS group of patients. Results Total quality of life score was poor in 23 cases (92.0%), and moderate quality of life score in 2 cases (8.0%). The quality of life score was lower in SARS group than that of control group (P<0.01). Data of TLCOc SB was lower in SARS group than that of control group. The score of physiological function was positively correlated with FEV1 and FEV1/FVC. The score of physical pain was positively correlated with FEV1/FVC (P<0.05). There were no significant differences between quality of life score and pulmonary function indicators. There were 11 cases (44%) of avascular necrosis of femoral head, and 14 cases (56%) of non-avascular necrosis of femoral head in SARS group. The score of physiological function was lower in femoral head necrosis group than that of non necrosis group (P<0.05). ConclusionThe lower quality of life in patients with SARS is not only related with psychological factors but also related with physical factors. The damage of pulmonary function and (or) necrosis of femoral head affect the quality of life in patients with SARS, especially the physiological function.

Objective To explore the microsurgical method in treating ruptured aneurysms treatment and evaluating the treatment of the complication during or after the operation.Methods 36 cases of patients with intracranial aneurysm were analyzed retrospectively.All of the patients were subarachnoid hemorrhage (SAH) by CT scan on admission.The intracranial aneurysms were confirmed in 35 cases by DSA examination and A2 aneurysm was confirmed by explorative operation in 1 case.The microsurgical treatment was performed in 36 cases at the early or intermediate stage,22 cases were treated in the early stage,the other 14 cases were treated in the intermediate stage (early stage means within 3 days post SAH;intermediate stage means from 4 days to 10 days post SAH).Results After the operation,21 cases were GOS grade Ⅰ,4 cases were COS grade Ⅱ,4 cases were COS grade Ⅲ,4 cases were GOS grade Ⅳ.Of all the patients,CT scan was done after the operation,finding no intracranial bemorrhage,and cerebral infarction was disclosed in 5 cases.3 cases were dead,one suffered occipital lobe infaret after the PCoA aneurysm clipped,brain hernia occurred at last,one's Hunt Hess grade was Ⅴ,ACoA aneurysm was disclosed by DSA examination,severe brain edema occurred after the operation,the other suffered tonsillar hernia one week after the aneurysm clipping,which ruptured after endovascular treatment of ACoA aneurysm 2 years later.DSA examinations were done in 26 cases after operation,declaring 1 ACoA aneurysm was unclipped,1 PCoA aneurysm was incompletely clipped,and 1 PCoA was sacrificed.Conclusions It is a valuable method to clip the ruptured intracranial aneurysms in early and intermediate stage.The cerebral ischemia is the severe complication after clipping.Especially for the PCoA aneurysms,it is very important to protect the PCoA.Further research should be done for the treatment in the case with mother artery arteriosclerosis and thrombosis within the aneurysms.

OBJECTIVE To invest igate the therapeutic effect and mechanism of PPAR gamma agonist on allergic rhinitis(AR) in mice. METHODS AR murine model was established by OVA sensitization and challenge. The behavior observation was used to understand the improvement effect of PIO on AR symptoms. The morphological characteristics of nasal tissues were observed by HE staining. The total RNA was extracted to investigate the level of mRNA expression of Foxp3, T-bet and GATA-3. The changes of CD4+Foxp3+T cells in spleen of mice were analyzed by flow cytometry. RESULTS BALB/c mice received OVA sensitization followed by OVA intranasal challenge, the frequencies of sneezing and nose-scratching increased signif icantly in AR group compared with control group. The frequencies decreased significantly in PIO group, compared with AR group. The continuity of nasal mucosa ciliated columnar epithelium in AR group was destroyed and appeared to be repaired in PIO group. Inflammatory cells infiltration was also markedly decreased by PIO treatment. PIO significantly increased the expression of Foxp3 mRNA(P ＜0.001) compared with AR and control group. There was no significant difference in T-bet between PIO group and AR group, but the expression of GATA-3 mRA in PIO group was significantly lower than AR group. The proportion of CD4+Foxp3+T cells in AR group (4.43％±0.25％) decreased compared with control group (5.19％±0.39％) (P ＜0.001). PIO treatment induced production of Tregs (6.35％±0.37％) compaered with control group(P ＜0.001). CONCLUSION PPAR-gamma agonist can effectively alleviate allergic symptoms of mice and regulate the balance of Th1/Th2. The role of PPAR gamma agonist in the treatment of AR may be the amplification of Tregs by promoting Foxp3 expression.

ObjectiveTo construct traditional Chinese medicine （TCM） diagnostic scale of turbid toxin syndrome in order to provide corresponding reference for the standardization of TCM syndromes and studies. MethodsWe systematically searched the Chinese Medical Dictionary （CMD）， China Knowledge Network （CNKI）， Wanfang Data Knowledge Service Platform （WF） and VIP database for TCM classics and modern literature on turbid toxin syndrome， and initially screened the four diagnosis information of turbid toxin syndrome， established a pool of information entries， and conducted a cross-sectional clinical survey. Discrete trend method， correlation coefficient method， Cronbach's coefficient method， and factor analysis method were applied to objectively screen the entries. The diagnostic scale of turbid toxin syndrome were constructed through three rounds of Delphi method expert survey to determine the scale entries， using hierarchical analysis to get the judgement matrix scores and relative weight of each entry， after passing consistency test and then isometric expansion of the relative weight of the entries to get the weight of each entry and assign the value. ResultsA total of 35 articles were included， 45 entries were obtained after the initial screening. After the clinical investigation， 12 entries were not suitable by the discrete trend method， 23 entries not suitable by correlation coefficient method， 13 entries by the internal consistency screening were removed with the Cronbach's alpha coefficient rising， and 10 entries not suitable by the factor analysis method. Twenty-two entries were retained after objective screening by the combined use of the four statistical methods. The positive coefficients of experts in the three rounds of Delphi method of expert consultation were 96.67%， the coefficients of expert authority were 0.834， 0.856， and 0.867， and the coefficients of co-ordination were 0.126， 0.326， and 0.312， respectively. After consulting with clinical experts， and three rounds of Delphi method survey and hierarchical analysis method weight assignment， the diagnostic scale entries of turbid toxin syndrome were finally established. Primary symptoms： dark red or purple and dusky tongue， yellowish greasy or dry coating （10 points）； sticky and unpleasant stools （8 points）； disharmony of tastes including halitosis， sticky and greasy taste in the mouth， dry mouth and bitter taste in the mouth （6 points）； unfavourable or yellowish or red urination （5 points）； and dark complexion （4 points）. Secondary symptoms： heavy body （3 points）； dizziness （3 points）； profuse， sticky， foul-smelling secretions （2 points）； wiry and slippery， or slippery， or slippery and rapid pulse （2 points）； feeling of hardness in the abdomen （1 point）. ConclusionUsing Delphi method combined with the hierarchical analysis method， combining qualitative and quantitative study， a diagnostic scale of turbid toxin syndrome was initially developed.
