Objective To investigate the clinical values of extracapsular invasion at sentinel lymph nodes in patients with breast cancer.Methods From Jan,2010 to Jan,2013,80 patients underwent axillary lymph node dissection due to sentinel lymph nodes invasion were enrolled in this prospective study.Patients were signed to extracapsular at sentinel lymph nodes positive group (n =45)and control group (n =35)according to the intra -operative pathology.The primary outcome was rate of positive non -sentinel lymph nodes and the second outcomes were 3 -year recurrence -free survival,mortality and health -related quality of life.Results Compared with the control group,the patients in extracapsular at sentinel lymph nodes positive group got a significantly higher rate of positive non -sentinel lymph nodes (91.11% vs.28.57%,χ2 =33.321,P <0.001 );a significantly lower rate of 3 -year recurrence -free survival(57.78% vs.88.57%,χ2 =9.114,P =0.003);a significantly higher rate of mortality (17.78% vs.2.86%,χ2 =4.390,P =0.036);and a significantly lower level of health -related quality of life[(78.43 ±12.43)vs.(87.54 ±11.89),t =11.324,P =0.000].Conclusion Extracapsular invasion at sentinel lymph nodes was a reliable predictor for non -sentinel lymph nodes invasion and long -term clinical outcomes.

OBJECTIVE: To study the effects of fibroblast growth factor-21 (FGF-21) on acute inflammation induced by lipopolysaccharide (LPS) and its mechanism. METHODS: Mouse model of acute inflammation was established by injection of LPS and treated with FGF-21 at high, medium and low doses, the pathological changes were detected with HE staining, the expression level of TNF-α, IL-1β, IL-6 and IL-17 in serum and peritoneal macrophage were determined by ELISA and Real-time PCR. NF-κB p65 in macrophage cells was analyzed by confocal laser scanning microscope and Western-blotting. RESULTS: FGF-21 treatment reduced lung damage and inflammatory cell infiltration and decreased the expression level of TNF-α, IL-1β, IL-6 and IL-17 in both serum and peritoneal macrophage. The results of confocal laser scanning microscope and Western-blotting both showed that FGF-21 could inhibit NF-κB transferring to the nucleus. CONCLUSION: FGF-21 could regulate the immune system by acting on macrophage. Relieving the inflammatory response in mice through NF-κB signal pathway may be one of the mechanisms FGF-21 regulating immune system.

The progress in integrative medicine (IM) of coronary heart disease (CHD) in 2013 was summarized in this paper. Gratifying progress has taken place both in clinical studies and basic research of IM on CHD during 2013. We got some innovation in Chinese medical etiologies and pathogeneses of CHD. We also got some improvement in researches on Chinese medical syndromes in various fields. Many clinical studies have proved Chinese medicine and pharmacy is playing a role in preventing and improving CHD patients. In-depth basic researches on preventing and treating CHD by IM are gradually undergoing. Acting targets and mechanism are further clarified. Besides, we also pointed out the developing tendency of CHD researches and the current deficiency in CHD researches, hoping to provide reference for further studies in this field.

Objective To determine the prevalence and characteristics of the del(GJB6-D13S1830) in Connexin30(Cx30) gene in children with prelingual deafness.Methods Forty-six prelingual deaf children and 30 children with normal comprehension were obtained,and the del(GJB6-D13S1830)in the Cx30 gene were screened by polymerase chain reaction(PCR) in 2 groups.Results Three cases of 46 deaf children were found to have heterozygous del(GJB6-D13S1830) in Cx30 gene.The rest deaf children and the normal controls did not harbor this deletion.Conclusion The heterozygous del(GJB6-D13S1830) in Cx30 gene is one of causes of prelingual deafness.

Objective To evaluate the usefulness of magnetic resonance spectroscopic imaging in detecting local recurrence in patients with T3N0M0 prostate cancer after cryotherapy.Methods Sixty-five patients with T3N0M0 prostate cancer underwent cryotherapy.The preoperative data of conventional MRI,MRS,transrectal ultrasound (TRUS)-guided prostate biopsy were collected.After cryotherapy,the prostate specific antigen (PSA) of all patients was detected monthly.If PSA ＞5 μg/L,MRI,MRS,and TRUS-guided prostate biopsy were planned within a week.If PSA was unremarkable,MRI,MRS,and TRUS-guided prostate biopsy were planned 12 months after cryotherapy.The prostate was divided 6 regions and the cancerous and noncancerous were marked.The signal-to-noise ratio(S/N) of choline (Cho),citrate (Cit)and the ratios of Cho + creatine ( Cre)/Cit of each regions were measured in pre-operation and postoperation.The patients were divided into non-recurrence and recurrence group according to TRUS-guided biopsy.The S/N of Cho,Cit,and the ratio of Cho + Cre/Cit were compared between the groups before and after cryotherapy by using independent samples t-test.Results ( 1) Fifteen patients were confirmed local recurrence 12 months after cryotherapy,including 11patients with an evaluate PSA level and 4 patients with PSA umemarkable.(2) The S/N of Cho,Cit and the ratios of Cho + Cre/Cit in the cancerous and noncancerous regions before cryotherapy in the sixty-five patients were 25 + 9,11+ 5,and 18 + 5,and 39 ±12,2.33 +0.60,and 0.53 ± 0.19.There had significant difference between that of two groups ( t values were 11.36,9.81,and 13.39,respectively,P =0.00).(3) In the patients with non-recurrence,The S/N of Cho,Cit in the cancerous and noncancerous regions were 4 ± 2 and 3 ± 2 ( t =1.024,P =0.305 ),and 2 +2 and 4 ±3 (t =1.147,P =0.178) and no difference was found.In necrotic area,the ratios of Cho + Cre/Cit could not be calculated because of low level of the S/N of Cho and Cit.(4)In the patients with local recurrence after cryotherapy,the S/N of Cho and Cit in the cancerous and noncancerous regions were 17 ±3 and 3 ± 2 ( t =17.24,p =0.00 ),9 ± 2 and 3 ± 3 ( t =23.66,P =0.00 ) and a significant difference was found.The ratio of Cho + Cre/Cit in the recurrent area was no significant different compared with that of preoperation(t =1.214,P =0.256 ).In necrotic area,the ratios of Cho + Cre/Cit could not be calculated because of low level of the S/N of Cho and Cit.Conclusions MRS is a useful tool to evaluate the changes of the S/N of Cho and Cit,the ratios of the Cho + Cre/Cit and help diagnosis of local recurrence.
