Objective To compare the clinical effects of 2 common installation positions of the helical blade in the treatment of senile intertrochanteric fractures with proximal femoral nail antirotation (PFNA).Methods From January 2010 to December 2012,166 old patients with intertrochanteric fracture were treated by PFNA.According to the installation position of the helical blade in the femoral head on the postoperative X-ray films,they were divided into a C/C group (87 cases) where the helical blade was at the center of the femoral head in both anteroposterior and lateral views and an I/C group (79 cases) where the helical blade was at the inferior one-third of the femoral head in anteroposterior view and at the center in lateral view.There were no significant differences between the 2 groups in general data preoperation (P ＞ 0.05).The 2 groups were compared in terms of reduction quality,tip-apex distance (TAD),full weight bearing time,fracture healing time,and Harris Hip Score(HHS) at the last follow-up.Results C/C group had 83 patients followed for an average of 13.6 months and I/C group had 76 patients followed for an average of 13.3 months.There were no significant differences between the 2 groups regarding the good-to-excellent reduction rate [94.0％ (78/83) versus 94.7％ (72/76)],full weight bearing time (9.4 ± 1.5 weeks versus 9.3 ± 1.3 weeks),fracture healing time (17.8 ±2.3 weeks versus 17.2 ±2.3 weeks),or HHS (89.6 ±4.6 points versus 89.3 ±4.7 points) (P ＞ 0.05).There was a significant difference in TAD (21.14 ± 3.17 mm versus 24.96 ± 3.48 mm) between the 2 groups(t =-7.242,P =0.000).No infection or cut-out or other related complications of the helical blade occurred in either group.Conclusion The helical blade may lead to satisfactory clinical effects in the treatment of senile intertrochanteric fractures with PFNA no matter at which of the 2 positions it is installed.

To construct a recombinant adenovirus containing CDglyES fusion gene, which can directly inhibit human ovarian cancer cell and indirectly inhibit vascular endothelial cell growth. Methods:We constructed prAdCDglyES using a homolo-gous recombination method in bacteria. The prAdCDglyES was transfected to 293 packaging cells using liposome, in which rAdCDgly-ES was packaged and amplified. MTT was used to observe the proliferation inhibition effect of rAdCDglyES on human ovarian cancer cells and the growth inhibition effect of expressing products of rAdCDglyES on ECV-304. Results:The titer of rAdCDglyES was 1 × 1013.3 TCID50/L, whereas the inhibition rate on human ovarian cancer cell SKOV-3 was (83.1±6.3)%. This result is significantly different from the control rAd-LacZ, which had an inhibition rate of (24.1 ± 13.2)% (P<0.01). The concentrated culture supernatant from cells transfected with rAdCDglyES can inhibit ECV-304 cell proliferation at a rate of (78.7 ± 1.6)%. This rate is significantly different com-pared with that of the control with the same concentration of culture supernatant from cells transfected with rAd-CD, with an effect on ECV-304 cell shown by an inhibition rate of (23.9 ± 9.7)%(P<0.01). Conclusion:The results showed that the recombinant adenovirus rAdCDglyES could inhibit human ovarian cancer cells directly and indirectly.

Objective:To explore the efficacy and safety of Certolizumab pegol in patients with rheumatoid arthritis. Methods:Such databases as Pubmed, Medline, Embase, The Cochrane Library, WANFANG, CNKI, Science, CBM and VIP were searched from their establishment to March 2015 for collecting the randomized controlled trials comparing Certolizumab pegol and placebo in the treatment of RA. The meta-analysis was undertaken using RevMan5. 3 for Windows. Results:Ten publications and eight researches met the inclusion criteria with high quality. The results revealed CZP significantly improved the ACR20,ACR50,ACR70 response rates,and physical function. CZP was associated with a statistically significant reduction in Disease Activity Score in 28 joints-Erythrocyte sedimentation rate, arthritis pain, and fatigue. There were no significant differences of incidence of treatment-related adverse events between CZP group and placebo group. Conclusion:CZP significantly reduced the RA signs and symptoms,improved physical function and life quality as compared with the placebo in the treatment of RA. More large-scale RCTs are needed to evaluate the long-term efficacy and safety of CZP in the treatment of RA.

Objective To explore the related risk factors of central lymph node metastasis ( CLNM) of papillary thyroid microcarcinoma ( PTMC) and the application value of central lymph node dissection ( CLND) . Methods Totally 251 patients who were confirmed as PTMC by pathological biopsy were selected as the research object, and they were divided into the metastasis group (n=42) and the non-metastasis group (n=209) according to the status of lymph node metastasis. The general datum of the two groups were retrospectively analyzed, and the indexes with significant differences after univariate analysis were analyzed by non-conditional Logistic regression analysis. Treated the patients with lymph node metastasis through CLND, and the occurrence rate and recurrence rate of related complications were recorded during the 1 to 3 years of follow-up. Results The comparison of the location of the tumor, complicated adenoma, Hashimoto’ s thyroiditis, nodular goiter, and hyperthyroidism between the two groups was not statistically significant (P>0. 05). In the metastasis group, the rate of patients aged less than 45 years old and the percentage of male patients were both significantly higher than the non-metastasis group, and the difference was of statistical significance (P<0. 05). There were 25 cases (59. 5%) whose tumor diameter were 5~10 mm, 12 cases (28. 6%) with multiple lesions, and 22 cases (52. 4%) breaking through the envelope in the metastasis group, which were significantly higher than 70 cases (33. 5%), 23 cases (11. 0%) and 67 cases (32. 1%) in the non-metastasis group, and the differences were statistically significant (P<0. 05). In the metastasis group after operation, there was 1 cases (2. 3%) of hoarseness, 6 cases (14. 3%) of local numbness, 1 case (2. 3%) of nerve invasion, and 2 cases (4. 8%) of vascular invasion, and there was no choking cough report. During the period of 1 to 3 years of follow-up, there were only 2 cases of recurrence and the recurrence rate was 4. 8%. Conclusion Central lymph node metastasis mostly occurs in the male patients with PTMC who are less than 45 years old. And the main characteristics are diameter of tumor over 5 mm, multifocal lesions, with envelope penetration symptom and so on. In clinic, patients who meet the above-mentioned condition should be taken as the primary concern and given related prevention measures to reduce the occurrence risk of central lymph node metastasis. To treat patients with papillary thyroid microcarcinoma through central lymph node dissection can receive good curative effect and effectively improve the prog-nosis quality, and it is worthy of clinical promotion.
