[Objective]To evaluate the clinical application and results of the anterolateral acromial approach with minimal incision in the treatment of proximal humerus fracture.[Method]From December 2006 to December 2008,42 patients with proximal humeral fracture were treated by the anterorlateral acromial approach using locking plate.There were 25 males and 17 females.All the fractures were classified with AO/OTA classification.There were 5 A2-fractures,11A3-fractures,7 B1-fractures,12 B2-fractures,3 C1-fractures,4 C2-fractures.Anterolateral acromial approach with minimal incision was applied and the deltoid muscle was seperated to expose the fracture fragments.Under direct vision the direct and indirect reduction of the fractures were performed.The locking plate was inserted distally beneath the deltoid muscle and between the distal plate and the humeral shaft was adjusted through another small skin incision on the lateral upper arm.Locking screws were inserted to the proximal and distal plate.Operation time,incision length,blood loss,reduction,Neer scores at 1 year were analyzed in different time points.[Result]All the cases were completed with minimal incision.There were significant differences(P

[Objective]To explore the clinical effects of titanium plate and morselized hone grafting for the treatment of severe acetabular hone defect.[Method]A total of 27 patients with acetabular defects were treated with this procedure.According to AAOS,the acetabular defects were classified into various types:type Ⅰ in 6 cases,type Ⅱc in 4 and type Ⅲ in 17.The average preoperation Harris score were 37.The postoperative effect should be evaluated by clinical and X-ray manifestations.[Result]All patients were adopted this method to reconstruct the acetabular bone defects.The prosthetic dislocation was found in one case after operation,which was resulted from over-anteverted titanium plate impacted the greater trochanter.The part of trochanteric bone and impact factors were removed to healing.No complications were found in other patients.The average following up was 3 years and average Harris score was 87.The X-ray showed that none of the patients was presented the radiolucent lines in the acetabular mattress,bone transplantation,reconstructive titanium plate and interface of polyethylene liner.[Conclusion]The titanium plate and morselized bone grafting can repair the acetabular bone defects effectively and provide a solid initial fixation for prosthesis and restore the role of rotational center of hip.

Objective:To study the changes of iNOS expression in periodontal tissues of rats with periodontitis in orthodontic tooth movement. Methods:48 SD rats at 10 weeks were divided randomly into two groups: periodontitis teeth group and normal teeth group. The maxillary first molar was pulled mesially both in the two groups. 4 rats were executed each time after activation of pull-spring 1, 2, 3, 7,14 and 21d both in two groups. iNOS immunohistochemistry staining were done to compare the expression variations. Results: There were significant differences between the two groups in 2,3, 7, 14 and 21 d. The periodontitis teeth group had stronger positive signals. Conclusion: Periodontitis will increase the expression of iNOS in the rats periodontal tissue during tooth movement, and influence the reconstruction of periodontium.

Objective To evaluate the therapeutic effect ofBushen-Huoxue decoction combined with oral calcium and vitamin D for senile osteoporosis.Methods A total of 120 patients with OP were enrolled and randomly divided into aBushen-Huoxue decoction group (60 patients) and a elcatonin group (60 patients). Routine use of calcium and vitamin D was adopted. On this basis, theBushen-Huoxue decoction group was treated byBushen-Huoxue decoction combined with oral calcium and vitamin D, while the elcatonin group was treated by intramuscular injection of elcatonin with oral calcium and vitamin D. VAS of low back pain and bone joint pain was evaluated, the changes of BMD in the lumbar spine and femoral neck was observed, serum calcium and phosphorus, ALP concentration changes were also observed.Results After the treatment, the low back pain in the Bushen-Huoxue decoction group (3.30 ± 0.38vs.4.32 ± 0.51,t=11.148), bone joint pain (3.15 ± 0.22vs.3.87 ± 0.26,t=11.880) VAS were significantly lower than those in the elcatonin group.Bushen-Huoxue decoction group L2-4is BMD (L2: 0.74 ± 0.15 g/cm2vs.0.63 ± 0.14 g/cm2,t=4.153; L3: 0.75 ± 0.13 g/cm2vs. 0.70 ± 0.10 g/cm2,t=2.361; L4: 0.76 ± 0.06 g/cm2vs.0.71 ± 0.10 g/cm2,t=3.321) were significantly higher than those in the elcatonin group(P<0.05).Bushen-Huoxue decoction group serum calcium (2.36 ± 0.45 mmol/Lvs. 2.19 ± 0.17mmol/L,t=2.737), serum phosphorus (1.28 ± 0.12 mmol/Lvs.1.22 ± 0.13 mmol/L,t=2.627) were significantly higher than those in the elcatonin group (P<0.05), ALP (89.20 ± 9.41 U/Lvs.114.00 ± 11.80 U/L, t=12.733) was significantly lower than that in the elcatonin group (P<0.01).ConclusionBushen-Huoxue decoction can effectively improve the clinical symptoms of senile osteoporosis, and elevate BMD content.

The effective rates were 61.9% 3 months after transplantation,85.7% 6 months after transplantation, and 90.4% during a follow-up of 12-28 months (mean 18 months).Conclusion:It is feasible and effective to implant the neural stem cells expanded in vitro for treatment of CA,but the long-term effectiveness should be futher observed.

Objective To investigate the influence of perioperative continuing aspirin therapy on tooth extraction surgery in elderly patients with coronary heart disease.Methods A total of 926 patients with coronary heart disease who required tooth extraction were enrolled in this study.Among them,241 patients discontinued aspirin therapy before tooth extraction,685 patients continued aspirin therapy before tooth extraction.The entering rate of operation was evaluated.100 patients continuing aspirin and 100 patients discontinuing aspirin were randomly selected.Systemic pressure,diastolic pressure and heart rate before and after tooth extraction were detected.100 matched healthy elderly patients were selected as normal control group.Multivariate logistic regression analysis was used to estimate the risk for tooth extraction.Results The entering rate of operation was 67.9％ (131 cases) in 193 patients with angina pectoris discontinuing aspirin therapy and 82.1 ％ (312 cases) in 380 patients with angina pectoris continuing aspirin therapy (x2 =14.77,P＜0.01).The entering rate of operation was 41.7％ (20 cases) in 48 patients undergoing coronary revascularization and discontinuing aspirin therapy,and 80.7％ (312 cases) in 305 patients undergoing coronary revascularization and continuing aspirin therapy (x2=33.95,P＜0.01).The changes in systolic blood pressure before versus after dental extraction had a significant difference between the discontinuing aspirin group and control group [(15.9±5.5) mmHg vs.(12.2±4.7)mmHg,P＜0.05,1 mmHg=0.133 kPa],while had no significant difference between the continuing aspirin group and control group [(13.6±4.5) mmHg vs.(12.2±4.7) mmHg,P＞0.05].There were no significant differences in changes in diastolic blood pressure and heart rate in the intraoperative period between the patients and controls (P＞0.05).The bleeding rate in patients continuing aspirin therapy was not significantly different as compared with control group (P＞ 0.05).Multivariate logistic regression analysis revealed that perioperative discontinuing aspirin therapy remained the second significant risk factor for tooth extraction.Conclusions Preoperative administration of aspirin should be continued in dental extraction surgery in elderly patients with coronary heart disease.

BACKGROUND: With the continuous renewal and development of clinical repair techniques, the intraoperatie blood loss has been greatly reduced in the treatment of intertrochanteric fracture; however, no matter what kind of repair methods should be adopted, there are stil a large amount of perioperative hidden blood loss, however, there are few clinical reports for the reasons and related factors. OBJECTIVE: To study the correlation of perioperative hidden blood loss with gender and internal fixation methods in the surgery of elderly femoral intertrochanteric fractures.METHODS: Total y 121 patients with elderly femoral intertrochanteric fractures who received the treatment at Department of Orthopedics, Nanyang City Center Hospital from March 2010 to June 2013 were divided into two groups according to the condition and treatment wishes of patients, and were respectively treated with dynamic hip screw and proximal femoral anti-rotation intramedul ary nail internal fixation. The preoperative hidden blood loss, postoperative hidden blood loss, the total hidden blood loss, dominant blood loss and total blood loss of patients in these two groups were compared. The multiple linear regression analysis on the correlation of perioperative hidden blood loss with gender and internal fixation methods was conducted. RESULTS AND CONCLUSION: There was no significant difference in the preoperative hidden blood loss between these two groups (P > 0.05). The total blood loss, postoperative hidden blood loss and total hidden blood loss in the proximal femoral anti-rotation intramedul ary nail group were significantly higher than those in the dynamic hip screw group (P < 0.05), and the dominant blood loss was significantly lower than that in the dynamic hip screw group (P <0.05). There were significant differences in the preoperative, postoperative hidden blood loss and total hidden blood loss between males and females (P < 0.05), and above indexes in males were significantly lower than in females. The multiple linear regression analysis showed that gender and internal fixation methods were correlated with hidden blood loss (P < 0.05). These results suggest that the perioperative hidden blood loss in surgery for elderly femoral intertrochanteric fractures is closely related to gender and above indexes in internal fixation methods. The perioperative hidden blood loss of male patients is less than that of female patients, and the patients treated with proximal femoral anti-rotation intramedul ary nail fixation have more hidden blood loss than dynamic hip screw fixation.

BACKGROUND:Proximal femoral locking plate and proximal femoral nail anti-rotation are the two common methods for the treatment of femoral intertrochanteric fractures in clinic. However, there were few randomized control ed trials on the comparison of both methods. Most of them are retrospective case analysis, and short of systematic evaluation. OBJECTIVE:To systematical y evaluate the clinical outcomes and safety between locking compression plate and proximal femoral nail anti-rotation for the treatment of the femoral intertrochanteric fractures. METHODS:The Cochrane Library (No.2 in 2015), PubMed(1966-01/2015-06), MEDLINE (1966-01/2015-06), EMbase (1984-01/2015-06), CNKI (1979-01/2015-06), VIP(1989-01/2015-06)and WanFang Data(1990-2015)were searched by computer. Meanwhile, relevant literature from the relevant journals and references were searched by hand. Al the randomized control ed trials concerning locking compression plate and proximal femoral nail anti-rotation for the treatment of the femoral intertrochanteric fractures were col ected. The literature was strictly filtered out according to the inclusion criteria, and was strictly evaluated for the quality. Meta-analysis on the included results was performed with RevMan5.2 software from the Cochrane col aboration. RESULTS AND CONCLUSION:There were 54 potential y relevant papers, and final y, 11 randomized control ed trials were eligible for this investigation. A total of 917 patients were included containing locking compression plate group (464 cases), proximal femoral nail anti-rotation group (453 cases). The Meta-analysis results showed that there were no significant differences in Harris scores, excel ent rate, complications, fracture healing time and hospital stays after treatment between the locking compression plate and proximal femoral nail anti-rotation groups. However, there were significant differences in the time of operation [MD=15.80,95%CI(7.57-24.04), P=0.000 2], peri-operative blood loss [MD=98.01, 95%CI(58.57-137.44),P<0.01], ambulation loading time [MD=8.07,95%CI(3.02-13.12),P=0.002], the length of incision [MD=6.90,95%CI(1.07-12.73), P=0.02] and postoperative drainage volume [MD=41.85,95%CI(23.77-59.93),P<0.01]. These results suggest that the treatment of proximal femoral nail anti-rotation had shortened the length of incision and the time of operation. The treatment of locking compression plate took more time of ambulation loading time, more peri-operative blood loss and postoperative drainage volume. Because the number of cases which this study included are few, and the fol ow-up time was shorter, we should design stricter large sample randomized control ed studies in future increase the strength of the evidence by conducting medium and long-term fol ow-up.

OBJECTIVE:To explore the effects of dehydroepiandrosterone(DHEA)combined with Meloxicam tablets on thera-peutic efficacy of osteoarthritis and biochemical indicator. METHODS:104 patients with osteoarthritis were randomly divided into ex-perimental group and control group with 52 cases in each group. Control group only received Meloxicam tablets,7.5 mg/time,bid;ex-perimental group was additionally given DHEA,25 mg/time,qd,on the basis of control group. The treatment course of 2 groups was four weeks. The clinical efficacy,VAS score before and after treatment,joint function score,levels of IL-1β and TNF-α,cartilage thickness,synovial thickness and score of liquid aggregation of joint cavity were compared between 2 groups. RESULTS:The total ef-fective rate of experimental group(86.54%)was significantly higher than that of control group(69.23%),with statistical significance (P<0.05);compared with before treatment,VAS scores of 2 groups decreased significantly after treatment,while joint function scores increased significantly,with statistical significance(P<0.05). VAS score of experimental group was significantly lower than that of control group,while joint function score was significantly higher than control group,with statistical significance(P<0.05). Af-ter treatment,the serum levels of IL-1βand TNF-αin 2 groups significantly decreased,with statistical significance(P<0.05);those of experimental group were significantly lower than those of control group,with statistical significance(P<0.05);there was no statis-tical significance in the cartilage thickness between 2 groups before and after treatment(P>0.05). Compared with before treatment, the thickness of the synovial membrane and the score of liquid aggregation of joint cavity significantly decreased after treatment,with statistical significance(P<0.05);the thickness of synovial membrane and the score of liquid aggregation of joint cavity in experimen-tal group were significantly lower than in control group,with statistical significance(P<0.05). CONCLUSIONS:DHEA combined with Meloxicam tablets is significant in the treatment of osteoarthritis,can significantly relief the pain and decrease the levels of serum IL-1βand TNF-α.
