Objective To explore the clinical significance of combined detection of plasma BNP and cTnⅠin predicting the prognosis of patients with acute heart failure.Methods 88 patients with acute heart failure were selected in emergency department of our hospital.According to the outcomes of patients'condition,the patients were divided into improved and discharged group (n =58)and died group (n =30).And 50 healthy people were selected as control group during the same period in our hospital.The changes of cTnI and BNP levels in the three groups were compared and analyzed.Results Compared with the control group,in the improved and discharged group and died group,the levels of cTnI were (1.09 ±0.91)ng/mL and (3.07 ±1.35)ng/mL,the levels of BNP were (182.76 ± 34.19)pg/mL and (226.84 ±51.73)pg/mL,which were significantly increased,the differences were statistically significant (t =9.15,9.90,26.11,13.99,all P <0.05 ).Compared with the control group,the patients before discharge in improved and discharged group,the levels of cTnI and BNP were (0.09 ±0.05)ng/mL and (65.33 ± 20.61)pg/mL,which were increased,the differences were not statistically significant (t =1.35,0.83,all P >0.05). Compared with the control group,the patients before death in died group,the levels of cTnI and BNP were (4.38 ± 1.59)ng/mL and (254.39 ±62.81 )pg/mL,which were significantly increased,the differences were statistically significant (t =12.09,13.52,all P <0.05).Compared with the improved and discharged group,the patients in died group admitted to hospital and before death,the levels of cTnI and BNP were increased significantly,the differences were statistically significant (t =6.16,3.59,12.06,13.25,all P <0.05).Compared with the cardiac function in patients with grade Ⅲ,the cardiac function in patients with grade Ⅳ,the levels of cTnI increased significantly,the difference was statistically significant (t =6.64,P <0.05).Conclusion Combined detection cTnⅠ and BNP has a guiding value for the prognosis of patients with acute heart failure.It provides a reference for clinical treatment.

Objective To compare the clinical outcomes between proximal femoral nail antirotation (PFNA) combined with salmon calcitonin and PFNA only for the treatment of unstable intertrochanteric fractures in elderly patients.Methods From January 2009 to December 2011,120 elderly patients with intertrochanteric fracture were randomly divided into two groups:calcitonin group and control group.Patients in calcitonin group were treated with PFNA combined with salmon calcitonin,while patients in control group were treated with PFNA only.According to Evans-Jensen classification,60 patients in calcitonin group (28 males and 32 females,with an average age of 75.1 years) were divided into 20 cases of type Ⅱ A,32 cases of type Ⅱ B and 8 type Ⅲ.Sixty patients in control group (27 males and 33 females,with an average age of 74.9 years) were divided into 22 cases of type Ⅱ A,32 cases of type Ⅱ B and 6 type Ⅲ.Bone healing was assessed with X-ray and bone mineral density (BMD) was measured by dual energy X-ray absorptiometry.Harris hip and SF-12 score,complications,adverse effect of salmon calcitonin and subsequent fragility fractures were evaluated postoperatively.Results One-hundred and thirteen patients were followed up for at least 2 years.In 6 months after surgery,there were 4 cases of delayed healing in control group.However,all fractures were healed in 12 months after surgery.No significant difference was found between the two groups in BMD preoperatively.The changes in BMD were significantly different between the two groups in 6 months,1 year and 2 years after surgery.No significant difference was found between the two groups in Harris hip and 1-year SF-12 score while the 2-year SF-12 score was significantly different between the two groups.There was 1 patient in calcitonin group who suffered from subsequent fragility fracture in 3 months after surgery,while there was 6 patients in control group during 13 to 23 months postoperatively.Conclusion PFNA combined with salmon calcitonin achieves good effect for the treatment of unstable intertrochanteric fractures in elderly patients.

Objective To evaluate the optimized simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) plans in cervical esophageal carcinoma underwent prophylactic lymphatic irradiation.MethodsSix patients with cervical esophageal carcinoma were studied.The gross tumor volume (GTV) and clinical target volume (CTV) (including bilateral mid-lower neck and supraclavicular lymph drainage regions,upper mediastinal lymph drainage regions) were delineated on sim-CT images,GTV and CTV were uniformly expanded by 5 mm to create PGTV and PTV.Five fields(5F) ,7F and 9F SIB-IMRT plans were designed.The prescribed doses to PGTV and PTV were 66 Gy and 60 Gy in 30 fractions respectively.The parameters of dose-volume histograms in three groups planning were compared.Results The values of conformity index(CI) of PGTV were 0.56,0.62 and 0.69 (F =6.22,P ＜0.01 ),the V66 with 88.24% ,95.03% and 94.91% ( F = 4.39,P ＜ 0.05 ) and D95 with 6539.67,6601.83 and 6602.00 cGy (F=4.46,P ＜0.05) in 5F,7F and 9F SIB-IMRT plans.The values of CI,V66 and D95 of PTV were 0.80,0.85 and 0.87 (F=11.29,P＜0.01),with 91.64%,94.05% and 95.06% (F=4.10,P＜0.05) and with 5934.00,5987.17 and 6006.33 cGy (F =4.01,P ＜0.05).The values of maximal dose of spinal cord were 4707.17,4497.83 and 4357.00 cGy( F = 11.26 ,P ＜0.011 ) in 5F ,7F and 9F SIB-IMRT plans.The values of all dosimetic parameters about PGTV and PTV were same in 7F and 9F SIB-IMRT plans ( all P ＞ 0.05 ).Conclusion 7F-SIB-IMRT plan is best one scheme for cervical esophageal carcinoma underwent prophylactic lymphatic irradiation.

One hundred and twenty patients with senile primary osteoporosis were enrolled in the study from January 2012 to April 2013,including 41 males and 79 females.Patients were randomly assigned to two groups:60 patients in study group were treated with salmon calcitonin combined with zoledronic acid (salmon calcitonin 50 IU i.m,q.d for 7 d,then 100 IU q.i.d for 7 d,followed by zoledronic acid 5 mg i.v gtt/y);60 cases in control group were treated with alendronate (70 mg p.o/wk).Both groups received the same doses of calcium.Visual analogue scale (VAS) scores were assessed before,and 1,6 and 12 months after treatment,12-Item Short-Form Health Survey (SF-12) and bone mineral density (BMD) were assessed before and 12 months after treatment.There were no significant differences in all baseline parameters between two groups (P ＞ 0.05).After 1 month of treatment,the VAS scores of study group was lower than that of the control group (2.1 ± 3.0 vs.4.2 ± 3.1,P ＜ 0.05),however,both groups had similar improvements in VAS scores in 6 and 12 months after the treatment (P ＞0.05).Compared to those before treatment,physical component summary and mental component summary of SF-12 scores after 1 year of treatment were improved significantly in both groups (P ＜ 0.05).Also,BMD was significantly improved after 1 year of treatment in both groups (P ＜ 0.05).The incidence of side effect in study group was lower than that in control group (16％ vs.20％,P ＜0.05).The results indicate that salmon calcitonin combined with zoledronic acid is an effective,safe,reliable and well tolerated therapy for senile primary osteoporosis.The long-term outcomes remain to be determined.

Objective To compare the clinical results of arthroscopic rotator cuff repair using a suture bridge technique and conservative therapy as treatment of traumatic shoulder dislocation combined with rotator cuff injury in older patients. Methods From August 2010 to August 2013 a total of 63 patients were prospectively enrolled. In the case of documented tears of the rotator cuff in combination with symptoms persisting after conservative therapy, patients were free to decide between arthroscopic rotator cuff repair using a suture bridge technique and conservative treatment. Patients were monitored for changes in visual analogue scale (VAS) scores, range of motion, the Simple Shoulder Test (SST), the Constant score and recurrences over a minimum follow-up period of 1 year. Results 60 pa-tients (30 in surgical group and 30 in conservative treatment group) were follow-up for at least 1 year. There was no significant difference between the two groups at baseline. The surgical group resulted in better improvements in pre-operative to postoperative VAS scores, range of motion, SST scores and the Constant score. There were five recur-rences in the conservative treatment group, while no recurrences were documented in surgical group. Conclusion In this selected patient group, we believe arthroscopic repair using a suture bridge technique for the treatment of symp-tomatic rotator cuff tear can improve shoulder function and decrease recurrences in older patients suffered from trau-matic shoulder dislocation combined with rotator cuff injury. The long-term outcomes remain to be determined.

During the postoperative follow -up period,the incidence rate of complications of the observation group (4.00%) was significantly lower than the control group (24.00%)(χ2 =4.15,P <0.05).Conclusion For patients with level of Ⅲ meniscus tear,arthroscopic FaxT -Fix technology vertical mattress suture can effectively reduce the surgery and hospitalization time,promote functional recovery of the patients 'knee,significantly improve the postoperative Lysholm knee score and IKDC,but also significantly reduce postoperative wound infection,hematoma,nerve damage vascular complication rate.

Objective To investigate the clinical outcomes of arthroscopic rotator cuff repair using improved-press-ift double-row technique for patients of large rotator cuff tear.Methods From December 2013 to November 2014, 52 patients (20 males, 32 females) with a full-thickness large rotator cuff tear underwent arthroscopic improved-press-ift double-row repair were retrospectively analyzed. The mean age of the patients was 65.6 years (range 51 to 76 years). The visual analog pain scale scores (VAS), the range of motion (ROM), University of California at Los Angeles (UCLA), and American Shoulder and Elbow Surgeons (ASES) were used for clinical and functional evaluations before surgery and at the time of 6 months after arthroscopy.Results The mean duration of follow-up was 10.9 months (range 6 to 17 months). At the time of 6 months after arthroscopy, the mean subjective pain score (VAS) was (1.6 ± 0.9), the mean active forward flexion was (145.6 ± 10.7)°, whereas the mean external rotation at the side was (30.8 ± 8.5)°. The mean UCLA score improved to (32.3 ± 3.5), the mean ASES score improved to (81.8 ± 8.7). There was significant difference postoperatively (P < 0.05). No re-tear occurred.Conclusion The improved-press-ift DR technique is effective in arthroscopic large rotator cuff repairing. Compared with suture-bridge technique, this technique can decrease operation time, costs, and is much easier to process.

Objective To investigate the changes in plasma microRNA-126 and microRNA-1 in children with asthma exacerbation and its relationship with bronchial asthma.Methods From October 2012 to December 2013,48 children with asthma exacerbation from the Outpatient Department and the Inpatient Department in Houjie Hospital Affiliated to Guangdong Medical College were enrolled in the study (asthma group).Meanwhile,52 healthy children wcre selected as the healthy control group.The expression levels of plasma microRNA-126 and microRNA-1 were detected by real-time quantitative PCR (RT-PCR).The content of interleukin-4 (IL-4) and interferon-γ (IFN-γ) in plasma was measured by enzyme-linked immunosorbent assay (ELISA).The predictive value of microRNA-126 and microRNA-1 in plasma to bronchial asthma was evaluated by receiver operating characteristic (ROC) curve.Results The relative expression levels of plasma microRNA-126 in the asthma group were upregulated compared with those in the healthy control group [7.36 (0.96-41.21) vs 3.68 (0.75-38.91),Z =3.135,P =0.038],and microRNA-1 relative expression levels in the asthma group were lower than those of the healthy control group [2.17 (0.18-26.97) vs 5.83 (0.82-39.62),Z =2.156,P =0.045].The content of IL-4 in asthma group was higher than those of the control group [(109.98 ± 74.58) ng/L vs (78.50 ± 75.82) ng/L,t =2.122,P =0.036],and the IFN-γ level in the asthma group was lower than those of the healthy control group [(70.49 ± 12.03) ng/L vs (77.03 ± 17.16) ng/L,t =2.270,P =0.025].In the plasma of patients with asthma exacerbation,the sensitivity of microRNA-126 and microRNA-1 was 85.42％ (41/48 cases)and 79.17％ (38/48 cases),respectively.The specificity of microRNA-126 and microRNA-1 in healthy controls was 78.85％ (41/52 cases) and 73.08％ (38/52 cases),respectively.The area under ROC curve of microRNA-126 and microRNA-1 was 0.919 (95％ CI 0.866-0.973),0.867 (95％ CI 0.796-0.939).Conclusions MicroRNA-126 is significantly elevated in plasma of children with asthma exacerbation.The plasma levels of microRNA-1 were significantly downregulated.These results suggest that microRNA-126 and microRNA-1 may be potential markers for the diagnosis of bronchial asthma.
