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.

Objective To analysis the effective ingredients in Huanglianjiedu decoction under different decocting conditions. Methods The detecting method of HPLC was established and the ingredients in Huanglianjiedu decoction under different decocting time and times were analyzed. Result Water- soluble glycoside of gardenoside and baicalin reached balance of dissolution within 20 min and their dissolution rate were about 82% and 60% respectively. Water-soluble alkaloids of berberine and palmatine reached balance of dissolution within 30 min and their dissolution rate were about 45%. The dissolution rate of wogonin was 31% at 60 min. The dissolution rate of Crocin-Ⅰ reached top at 20 min and fell down after 20 min. Decocting times for fat-soluble constitutes was more important than water-soluble constitutes. Conclusion The decocting condition has effect on the dissolution rate and stability of the ingredients in Huanglianjiedu decoction. The decocting condition is very important to the quality control of decoction.

Objective: To investigate the effectiveness of anatomical locking plate internal fixation combined with coracoclavicular ligament reconstruction in treatment of the Neer type Ⅱb distal clavicle fractures by comparing with the simple anatomical locking plate internal fixation. Methods: The clinical data of 40 patients with Neer type Ⅱb distal clavicle fractures who met the criteria between February 2013 and January 2017 were analyzed. Eighteen cases were treated with anatomical locking plate internal fixation and coracoclavicular ligament reconstruction by using a suture anchor (reconstruction group), and 22 cases were treated only with anatomical locking plate internal fixation (non-reconstruction group). There was no significant difference in gender, age, injured side, causes of injury, associated injuries, time from injury to operation between 2 groups ( P>0.05). The operation time, medical expense, postoperative coracoclavicular distance, Constant-Murley scores of injured side, and complications were recorded and compared between 2 groups. Results: All patients were followed up 12-27 months (mean, 16.3 months). One patient in reconstruction group had superficial wound infection. One patient in non-reconstruction group had pullout of screws from the distal fragment and reduction loss at 1 month postoperatively. The operation time and medical expense in reconstruction group significantly increased when compared with those in non-reconstruction group ( P<0.05). All fractures in 2 groups achieved bony union at last follow-up. The rate of coracoclavicular distance increase of injured side in non-reconstruction group was significantly higher than that in reconstruction group ( t=2.371, P=0.023). The Constant-Murley scores at 1 month, 3 months after operation, and last follow-up were significantly improved when compared with preoperative values in 2 groups ( P<0.05), but no significant difference was observed between 2 groups ( P>0.05). Conclusion: Both anatomical locking plate internal fixation with and without coracoclavicular ligament reconstruction can achieve good effectiveness for the Neer type Ⅱb distal clavicle fractures. Therefore, the coracoclavicular ligament reconstruction does not need, except for comminuted fractures with the length of lateral fragment less than 1 cm or the patients with poor compliance.
