Objective To research the impact of axillary limph node group dissection oriented by senti-nel lymph nodes instead of axillary dissection on upper limb lymph edema and disease -free survival ( DFS ).Methods We designed a randomized controlled research , which included 205 cases of operatable breast cancer (AJCC 7th:stage I or stage IIa)from Jan.2011 to Jan.2013.Those cases were separated into 2 groups randomly ( random number method ):group A underwent mastectomy ( or lumpectomy ) and axillary group lymphadenectomy oriented by sentinel lymph node biopsy ( SLNB) ( if positive continued for ALND ) while group B underwent mastec-tomy(or lumpectomy)and axillary lymph node dissection(ALND).All patients underwent SLNB by blue dye method and received adjuvant therapy after surgery according to National Comprehensive Cancer Network ( NCCN) guideline and Chinese anti-cancer association guideline .Results There were 101 cases in group A and 104 ca-ses in group B , but 1 case in group A was excluded for false negative of SLN.The midium follow-up was 30 months.There were no significant differences of average age , tumor size, grade, estrogen receptor (ER),proges-terone receptor ( PR) and human epidermal growth factor receptor 2 ( HER2 ) expression between the 2 groups. Group A had a lower frequency of lymph edema than group B (4.0%vs 17.3%,χ2 =9.384,P=0.002), and al-so a milder degree ( mild 2%vs 11.5%,middle 2%vs 3.8%,severe 0%vs 1.9%).There were no significant differences of upper limb sensory disorder (14.0%vs 16.3%,χ2 =0.218,P=0.641), neither of DFS(Log-Rank analysis:3-year average DFS 32.89 months vs 33.72 months,χ2 =0.186,P=0.667;Cox risk model analysis:HR=1.395,P=0.495)between the 2 groups.Conclusion Axillary group lymphadenectomy oriented by SLNB can reduce the happening of lymph edema from ALND and has a comparative effect on DFS as ALND .

Objective To investigate expression of TPS, VEGF of beast cancer patients and relationship with clinical pathological.Methods 68 cases of breast cancer were selected as experiment group, 36 cases with breast fibroma were selected as control group.TPS and VEGF were detected by elisa of patients before and after treatment.Serum TPS and VEGF levels and TNM staging were compared after operation.Results TPS and VEGF of the experiment group were higher than control group(P<0.05).TPS and VEGF of experiment group after operation were higher than before operation.TPS and VEGF increased with the grade of tumor, but there was no significance between grade Ⅰ and 0.The expression of VEGF in tumor diameter≤2 cm group was significantly lower than >2 cm group(P<0.05).TPS and VEGF of axillary lymph node metastasis group and axillary lymph node metastasis had significant difference(P<0.05).The concentration of TPS was significantly higher than that of estrogen and progesteronepositive group in estrogen receptor negative, progesterone receptor negative (P<0.05).Conclusion TPS, VEGF levels in the serum of breast cancer patients showed high expression, the expression of TPS, VEGF levels related to axillary lymph node metastasis, estrogen receptor, progesterone receptor.

Objective To investigate effect of anthracyclines of VEGF-C, VEGFR-3, ER and E-cadherin in serum of patients with breast cancer.Methods 43 patients with breast cancer were selected and randomly divided into experimental group and control group, 40 cases in each group.According to the experimental program based on the treatment, serum VEGF-C, VEGFR-3 levels and breast tissue ER and E-cadherin were detected after the end of the treatment.Results Compared with the control group, VEGF-C, VEGFR-3 levels of the experiment group were lower( P<0.05),ER level was lower(P<0.05) and E-cadherin level was higher(P<0.05).Conclusion the ER, VEGFR-3 and VEGF-C levels in breast cancer patients can significantly decrease the E-cadherin level, and it has a guiding significance for clinical.

The studies have shown that the genesis and development process of breast cancer is closely related with microRNAs (miRNAs).Multiple miRNAs are involved in the progress of the incidence of breast cancer,and can be used to assess the prognosis,clinical treatment of breast cancer,and to explore the resistance mechanisms.

Objective To investigate the clinical effects of synthetic medical calcium phosphate and calcium sulfate as the bone replacements for bone defects.MethodsA total of 85 bone trauma patients combined with bone defects treated between February 2000 and October 2011 were randomized to calcium phosphate group ( n =43 ) and calcium sulfate group ( n =42 ) according to bone substitutes.The patients had orthopedic conventional treatment and then received external fixation ( external fixators,plasters) or internal fixation (plates,needles).Forty-three patients in the calcium phosphate group were all treated with medical calcium phosphate and 42 patients in the calcium sulfate group were all treated with medical calcium sulfate.Postoperative complications,fracture healing time and bone substitute absorption time of the two groups were observed and compared.ResultsAfter artificial bone filling for bone defects,all fractures were healed,with average healing time of 12.5 weeks ( range,9-17 weeks) in the calcium phosphate group and 11.3 weeks (range,7-15 weeks) in the calcium sulfate group.No complications or abnormal reactions occurred in the calcium sulfate group,whereas four patients with incision exudation was founded in the calcium phosphate group,and was cured after dressing change.The average follow-up period was 54.5 weeks (range,14-70 weeks).Average absorption time of bone substitute for the calcium phosphate group was 7.3 weeks,longer than that for the calcium sulfate group (P ＜ 0.05 ).Conclusions Medical calcium phosphate and calcium sulfate artificial bones can both be used as bone substitutes and are characterized by convenience,safety and good healing under the auxiliary of internal and external fixators.The calcium sulfate is sturdier and has relatively stronger supporting ability than the calcium phosphate.As the bone substitute,the calcium sulfate has more precise clinical effects,fewer complications and shorter healing time than the calcium phosphate.
