Objective To compare the clinical outcome of unipedicular versus bipedicular vertebroplasty treating for osteoporotic vertebral compression fracture.Methods Sixty-four patients(68 vertebra)were divided into two groups by treated methods:unipedicular kyphoplasty group(33 cases)and bipedicular vertebroplasty group(31 cases).The Cobb angle and vasual analogue pain scale(VAS)were measured preoperatively and postoperatively.The operation time was recorded.Compared the Cobb angle,VAS and the operation time between two groups.Results Of unipedicular kyphoplasty group preoperative,24 hours and 3 months after operation,VAS were(8.42 ± 1.33),(2.21 ± 1.67),(2.09 ± 1.58)scores,the Cobb angle were(31.24 ±9.12)°,(14.21 ±9.21)°,(14.43 ±9.36)° ;while those of bipedicular vertebroplasty group were(8.36 ± 1.52),(2.13 ± 1.80),(2.00 ± 1.71)scores and(30.84 ±8.77)°,(13.94 ± 8.87)°,(14.07 ± 9.87)°.VAS and the Cobb angle of both groups at 24 hours and 3 months after operation were lower than those preoperative(P＜ 0.01).VAS and the Cobb angle of both groups were similar at the same time preoperatively and postoperatively(P ＞ 0.05).The operation time of unipedicular kyphoplasty group and bipedicular vertebroplasty was(45.00 ± 8.76),(72.00 ± 9.32)min,respectively,there was statistically significant difference between two groups(P ＜ 0.01).Conclusions Compared with the bipedicular vertebroplasty,the advantages of unipedicular kyphoplasty are as follows:less trauma,less operation time and less X-rays rediation accepted of the patient and the operator.And it has the similar clinical outcome with the bipedicular vertebroplasty.

Objective To study the influence of bFGF gene transfected bone marrow-derived mesenchymal stem cells (BMSCs) on the inflammatory cytokines of COPD rat. Methods The BMSCs were separated from SD rat and cultured and then bFGF gene was imported to BMSCs by liposome transfection method. The samples were prepared into six groups: normal control group, COPD group (A), BMSCs group (B), pcDNA3.1-BMSCs group (C), bFGF-pcDNA3.1-BMSCs group (D), and bFGF group (E). The expressions of TNF-α and IL-1β by QRT-PCR were detected. Results Compared with COPD group, TNF-α and IL-1β genes from groups B to D dropped significantly (P < 0.05). The changes of TNF-α and IL-1β genes among groups B to D showed no significant difference (P > 0.05). Conclusion BFGF transfected BMSCs, sample BMSCs and pcDNA3.1 transfected BMSCs can inhibit the expression of inflammatory cytokines of TNF-α and IL-1β, but there is no obvious advantage in comparison to bFGF transfected BMSCs and sample BMSCs in respect of inhibiting the expression of inflammatory cytokines of TNF-α and IL-1β.

Objective To investigate the effect of intrathecal gastrodin on skin cancer pain in mice.Methods Thirty-two female Balb/c mice,aged 8 weeks,weighing 20-25 g,were randomly divided into 4 groups (n=8 each) using a random number table:sham operation group (group S),skin cancer pain group (group SCP),gastrodin group (group G),and artificial cerebrospinal fluid (ACSF) control group (group ASCF).Skin cancer pain was produced by injecting phosphate buffer solution 20 μl containing about 2 ×105 4T1 breast cancer cells into the plantar surface of the left hindpaw.At 14th day after inoculation of cancer cells,ASCF 5 μl was injected intrathecally in S and ACSF groups,and gastrodin 150 μg/kg (5 μl) was injected intrathecally in group G.Before inoculation,at 30 min before intrathecal injection,and at 15,30,60,90,120 and 150 min after intrathecal injection,the thermal paw withdrawal latency (TWL) was measured.The expression of acid-sensing ion channel (ASIC)-3 mRNA in the spinal dorsal horn was detected using the real-time reverse transcriptase polymerase chain reaction after the last measurement of the pain threshold.Results Compared with group S,the TWL was significantly decreased at each time point before and after intrathecal injection in SCP,ACSF and G groups,and the expression of ASIC-3 mRNA in the spinal dorsal horn was significantly down-regulated in group G (P＜0.05).Compared with group SCP,the TWL was significantly increased at each time point after intrathecal injection,and the expression of ASIC-3 mRNA in the spinal dorsal horn was significantly down-regulated in group G (P＜0.05),and no significant change was found in the parameters mentioned above in group ACSF (P＞0.05).Conclusion Intrathecal gastrodin can reduce skin cancer pain and down-regulate ASIC-3 expression in the spinal dorsal horn which is helpful in maintaining the analgesic effect in mice.

Objective To explore the methodology of choosing the volume and shape of the mammary implant.Methods The changes of the volume and shape were analyzed in 502 cases of breast augmentation,to find out how to select the volume and shape of the mammary implant.Results The thoracic width H was the most important factor of choosing width of the implant; the SN was the important factor of choosing the height of the anatomic implant; After setting the diameter and height of the implant,a bigger breast could be achieved by increasing the projection of implants.For those very thin females with flat chest, anatomic implants were the better choice. Conclusions Thoracic width,breast volume and other data are the most important factors in choosing the mammary implant.Round and anatomic mammary implants have their specific indications.

BACKGROUND:There is no consensus on the choice of anatomic plate or dynamic hip screw for the treatment of intertrochanteric fracture. Current research is limited to smal-sample studies, and it is difficult to carry out a large-sample multicenter analysis. OBJECTIVE:To carry out Meta-analysis about the literature on anatomic plate versus dynamic hip screw in the treatment of intertrochanteric fractures, in order to evaluate the efficacy of anatomic plate versus dynamic hip screw in the treatment of intertrochanteric fractures. METHODS:The PubMed database (1995-2013), EMCC database (1995-2013), CBM database (1995-2013), CNKI database (1995-2013), VIP database (1989-2013) and Wanfang database (1995-2013) were searched by computer to col ect the control ed trials of anatomic plate versus dynamic hip screw for the treatment of intertrochanteric fractures. Then, the retrieved studies were screened according to predefined inclusion and exclusion criteria. The quality of the included studies was evaluated to extract useful y data, and Meta-analysis was performed by using the RevMan5.0 software. RESULTS AND CONCLUSION:A total of 19 control ed trials were included with a total of 1 730 cases. Among them, 764 cases were belonged to the anatomic plate group, and dynamic hip screw group included 966 cases. The Meta-analysis results indicated that there were no statistical y significant differences in fracture healing time, prognosis excellent and good rate and postoperative complications between two groups (P=0.34, 0.58, 0.80);the operative time, intraoperative blood loss and postoperative drainage volume in the anatomic plate group were lower than those in the dynamic hip screw group (P<0.000 01). The results indicate that anatomic plate and dynamic hip screw have the similar clinical efficacy for the treatment of intertrochanteric fractures, but the anatomical plate has relatively simple operation and less bleeding. Due to the poor quality of the included literatures and high bias occur and influence the effect, so more wel-designed multi-center randomized control ed trials should be performed to provide high-quality evidence.
