0.05). CONCLUSION: Comparatively speaking, Tacrolimus Ointment is safe and effective for local lichen simplex chronicus.

To investigate the effects of Tacrolimus ointment on patients with erosive oral lichen planus. A total of 62 cases were collected and divided into two groups randomly: 31 cases were treated with Tacrolimus ointment (treatment group), and 31 cases with clobetasol propionate ointment (control group). There was no significant difference between two groups of the effective rate and side-effect occurrence during the therapy, and relapse rate within six months after treatment. The results of the present work demonstrate that Tacrolimus ointment is an effective therapy for oral lichen planus.

Objective To compare the effects of surgical versus non-surgical treatment for femoral neck fractures in elderly patients,in order to provide guidance on treatment options.Methods The clinical effects and complications of different approaches from 42 patients with femoral neck fractures who had received treatment at our department from February 2006 to August 2011 were retrospectively analyzed.Results Of the 42 cases,13 cases were treated with artificial hip replacement,18 cases with hollow lag screw fixation,and 11 cases with tibial traction.No death occurred in patients treated with surgery,and 4 patients who had received non-surgical treatment died within 6 months of the followed-up.Conclusions Very elderly patients with femoral neck fractures generally perform well under appropriate perioperative care.Surgical treatment can produce good therapeutic effects,shorten the time for bed rest,improve the quality of life and reduce the mortality rate.

Objective To study the curative effect of anterior cervical discectomy with fusion (ACDF)and anterior cervical corpectomy with fusion (ACCF)for multi segment cervical spondylosis;and to provide effective anterior surgery for the disease.Methods According to digital table,106 cases with multi segment cervical spondylosis were randomly divided into ACCF group of 54 cases and ACDF group of 52 cases.The ACDF group was treated with ACDF,and the ACCF group was treated with ACCF.The operation time,bleeding volume and excellent rate of cervical functional improvement of the two groups were observed,and the bone graft fusion,cervical vertebra height change and the change of cervical curvature of the two groups were evaluated.Results The operation time of the ACDF group was higher than that of the ACCF group,the amount of bleeding of the ACCF group was lower than that of the ACDF group,and the differences werestatistically significant (t =2.857,9.097,all P <0.05 ).After 6 months and 12 months,the segments of the ACDF group were higher than those of the ACCF group,the differences were statistically significant (t =8.157,6.330,all P <0.05).After 6 months and 12 months,the section curvature increases and cervical vertebra increased curvature of the ACDF group were lower than those of the ACCF group,the differences were statistically significant (t =4.707,4.575,4.083,3.987,all P <0.05).The complication rate of the ACDF group was 11.5%(6 /52),which of the ACCF group was 13.0%(7 /54),the difference was not statistically significant (χ2 =0.050, P >0.05).Conclusion For multi segment cervical spondylosis,there are no significant differences in efficacy and stability between ACDF and ACCF;ACCF surgery field is more clear and easy to operate,the operation time is short, and there is the phenomenon of titanium mesh sinking.In the maintenance of cervical curvature,ACCF is better than ACDF.

Objective To observe the tissus implanted into the damaged articular cartilage of rabbits with induced autogeneic mesenchymal cells. Methods The autologous mesenchymal cells derived from bone marrow of New Zealand rabbits were harvested. With basic fibroblast growth factor(bFGF， 25 ng/ml) and transforming growth factor beta 1(TGF-? 1， 2 ng/ml)， the cells were induced and expanded in cell culture. The induced cells with absorbable gelatin sponge as a carrier were then implanted into the damaged articular cartilage in rabbits as experimental group. The absorbable gelatin sponge without cells were served as control. Specimens were harvested at the end of 4, 12 and 24 week after implantation, and were stained with toluidine blue. Results By RT- PCR, it was confirmed that there was expression of typeⅡ procollagen mRNA in the induced mesenchymal cell. After implantation, it was difficult to macroscopically distinguish the repaired tissues from the normal cartilaginous tissue in the experimental group in 24 weeks. While the defect of articular cartilage was filled with white and swampy tissue in the control group at the same time. Histologically, the defective area of the articular cartilage was replaced by the formation of neo- cartilage which showed positive staining of toluidine blue in 4 weeks in the experimental group. The neo- cartilage was modeled to normal cartilage tissues in 12 weeks and was similar to the surrounding cartilage in 24 weeks. But in the control group, the defect of articular cartilage was not repaired by cartilage tissue at every stage and were replaced by fibrocartilage which was shown weakly positive staining of toluidine blue in 24 weeks. Conclusion The transplant of the induced autogeneic mesenchymal cells derived from bone marrow might promote repair of articular cartilage, and restore its structure and function.

OBJECTIVE:To evaluate the role of PDCA cycle management on standardizing clinical use of atomization inhala-tion drug. METHODS:Using a retrospective method,300 medical records of atomization inhalation drug use were collected from our hospital during Jan.-Dec. in 2013(non-intervention group),200 medical records collected during Apr.-Jun. in 2014(one cycle intervention group),and 180 medical records collected during Oct.-Dec. in 2014(two rounds of cycle intervention group). The use of atomization inhalation drugs was compared before and after the application of PDCA cycle management. Before and after two cy-cle intervention,4 types of medical staff were investigated on cognition of the related knowledge of atomization inhalation drugs, as physicians,pharmacists,nurses and mechanic. RESULTS:After two rounds of PDCA cycle management and intervention,the proportion of unsuitable route of administration of antibiotics,long acting glucocorticoid,non-atomization inhalation dosage form of resolving phlegm drugs,protease decreased from 54.0%,62.0%,59.7%,44.7% before intervention to 0.6%,1.1%,15.0%, 1.1% after intervention;those phenomena had not been found,such as unsuitable route of administration of TCM injection and non-atomization dosage form of theophyllines,unsuitable atomization frequence,unsuitable indication,drug mixture for preventing and controlling symptom,etc. The proportion of medical staffs being familiar with medical device,drug classification,drug selec-tion for prerention and treatment and the proportion of hospital drug stock to 93.4%,86.7%,92.4%,96.2% after intervention from 38.0%,79.0%,49.0%,39.5%before intervention. CONCLUSIONS:The application of PDCA cycle management can effec-tively regulate the use of atomization inhalation drugs in our hospital;the method can be promoted and applied.

Objective To investigate the expression of p57kip2 and cyclin D1 in human brain glioma and its clinical significance.Methods The expression of p57kip2 and cyclin D1 was detected by SP immunohistochemical technique in brain glioma(n=55) and normal brain tissues(n=10).Results Positive rate of p57kip2 protein in the 55 cases of brain glioma was 38.2%(21/55),significantly lower than that in normal brain tissues(80%,P

Objective: To investigate the inhibition of tanshinoneⅡA (TanⅡA) on the proliferation of lung cancer cells. Methods: Human lung cancer cell lines A549, SK-MES-1, H446 and H460 were cultured in vitro and treated with TanⅡA at concentrations of 0.3, 0.6, 1.3, 2.5, 5.0, 10.0 mg/mL, while untreated cells served as controls. Cell proliferation was measured by using CCK-8 assay, and apoptosis was measured using flow cytometry, while the expression of apoptosis-related proteins was determined using Western blotting. The apoptotic rate of lung cancer cells was compared between Tan ⅡA-treated cells and untreated cells. Results: Tan ⅡA inhibited lung cancer cell proliferation in a time-dependent and concentration-dependent manner, and the survival rates of A549, SK-MS-1, H446 and H460 cells reduced with the concentration of TanⅡA (t=4.503, 2.114, 2.103 and 3.567; all P<0.05) and the duration of TanⅡA treatment (t=5.189, 3.079, 3.023 and 3.845; all P<0.05). The 48 h half maximal inhibitory concentrations (IC50 values) of TanⅡA were (1.18±0.12), (0.78±0.08), (1.55±0.16) and (1.27±0.14) mg/mL against A549, SK-MES-1, H446 and H460 cells, respectively. Following 48 h treatment with Tan ⅡA at a concentration of 2.5 mg/mL, the apoptotic rates of A549, SK-MS-1, H446 and H460 cells were (34.97±3.78)%, (37.62±2.48)%, (18.27±2.98)% and (19.17±2.30)%, which were significantly significantly higher than those of untreated cells [(4.86±0.36) %, (3.21±0.48) %, (3.25±0.26)% and (2.66±0.19)%, all P<0.05]. Reduced Akt1 protein expression, elevated Bax/Bcl-2 expression ratio, and elevated caspase-9 and caspase-3 protein expression were detected in lung cancer cells treated with 2.5 mg/mL TanⅡA for 48 h relative to untreated cells Conclusion TanⅡA may inhibit lung cancer cell proliferation in a time- and concentration-dependent manner via the Bax/Bcl-2/caspase-9/caspase-3 pathway.

Objective To investigate the effect of isokinetic training on stiff knees after fracture arrest. Methods 38 fracture patients were divided into observation group (n=19) and control group (n=19) by the medical number. Both 2 groups received the Chinese herbs fumigation and joint mobilization. Besides, the observation group received the isokinetic training, while the control group received the instrument training. The range of motion (ROM), maximum peak torque (PT), peak torque/body weight (PT/BW), average power (AP), and hamstrings/quadriceps (H/Q) were tested before and 16 weeks after training. Results The flexion, straightness and flexion radian became significantly better after training. The flexion and the increase of the flexion radian were significantly better in observation group than in control group after training. All indexes of the isokinetic test significantly improved after training (P<0.001) except H/Q (P>0.05). ROM、PT、PT/BW and AP of the knees joint were significantly better in the observation group than in the control group (P<0.001) after training, while there was no significant difference in H/Q between 2 groups (P>0.05) after training. Conclusion Isokinetic training can promote recovery of stiff knees of femur fracture.

Thirty-three patients with esophageal carcinoma (T3N1M0 or less) underwent thoracoscopic surgery in lateral prone position for esophagectomy from February 2010 to November 2012.Their postoperative outcomes and survivals were retrospectively analyzed.The results confirmed the feasibility and safety of this mini-invasive thoracoscopic procedure in lateral prone position for patients with esophageal carcinoma.A possible advantage of lateral prone technique is that in case of an emergency switch to open surgery,precious time may be saved in changing body position.
