Objective To investigate the clinical effect of the proximal femoral nail anti rotation nail combined with anti osteoporosis drugs in the treatment of intertrochanteric fracture in elderly patients.Methods From October 2014 to October 2015 in our hospital department of orthopedics for PFNA surgical treatment of 80 cases of intertrochanteric fractures in osteoporotic patients, according to the time of admission were divided into simple operation group (control group) and combined group (treatment group),with 40 cases in each group.Both the two groups were treated with PFNA surgery,treatment group were treated with ossification in three alcohol,calcium and calcitonin in the treatment of patients with hip.The fracture healing and hip function were compared between the two groups.Results The treatment group callus appear time,healing time were lower than the control group, the difference was statistically significant (P<0.05);One and three months after operation,the callus scoring of treatment group was higher than control groups (P<0.05);Six months after operation, the bone density of treatment group were higher than control group (P<0.05),the satisfactory rate of treatment group 90.00% was higher than the control group72.50% ( P<0.05 ) .Conclusion PFNA combined with anti-osteoporosis drugs in the treatment of elderly patients with intertrochanteric fracture is conducive to promote fracture healing , improve the condition of osteoporosis in patients with osteoporosis.

OBJECTIVETo establish a mouse model of spinal metastasis of human prostate cancer using fluorescence-labeled PC-3 cells to allow direct observation by in vivo imaging.

METHODSPC-3 cells were infected with a lentivirus carrying green fluorescence protein (GFP) gene. The GFP-positive cell clone was expanded and prepared into cell suspension for injection into the inferior vena cava of nude mice. The tumor growth and metastasis in the mice was directly observed using an in vivo fluorescence imaging system. The tumor-bearing mice were sacrificed after 3 months for histological examination with HE staining.

RESULTSThe labeled cells showed stable GFP expression both in vitro and in vivo. One week after cell injection, green fluorescence signals were detected by the in vivo fluorescence imaging system in the lower back of the mice, and at 4 weeks, the fluorescent tumor mass increased with a bone metastasis rate of 19% (3/16). Dissection of the mice at 3 months revealed lumbar tumor infiltration in 3 mice, showing a consistent result with in vivo fluorescence imaging.

CONCLUSIONThe nude mouse model of spinal bone metastasis of human prostate cancer established using GFP-labeled PC-3 cells facilitates further study of bone metastasis of prostate cancer.

Objective To explore the clinicopathological characteristics,diagnosis,treatment and prognosis of accessory breast cancer.Methods Clinical and pathological data of 37 accessory breast cancer patients from Dec 2005 to Aug 2017 were reviewed.Results 12 patients underwent breast-conserving local wide excision plus axillary lymph node dissection.5 cases were treated by segmental resection and 19 patients by Auchincloss or Halsted mastectomy;One patient abandoned surgery.The most common histological type of accessory breast cancer was infiltrating ductal carcinoma (26 cases,70.3％) followed by adenocarcinoma (4 cases) and miscellaneous type (7 cases).The most common AJCC pathological stages were stage Ⅱ (n =24,65 ％),Ⅰ (n =8),Ⅲ(n =3) and Ⅳ (n =2).The median follow-up time was 6 (1-12) years,the followup rate was 100％.Until Dec 2017,7 patients died from metastasis and the others were alive.Conclusions Accessory breast cancer is rare and with poor prognosis.The diagnosis depends on clinical manifestations,imaging and pathology.Surgery is the mainstay therapy,adjuvant chemo therapy is recommanded.
