OBJECTIVETo explore the feasibility and safety of dexmedetomidine combined with remifentanil for lower eyelid blepharoplasty.
METHODS50 patients undergoing lower eyelid blepharoplasty ASA I - II were randomly divided into 2 groups (25 in each group) as observation group and control group. Dexmedetomidine (0.3 microg x kg(-1) x h(-1)) and remifentanil (0.05 microg x kg(-1) x min(-1)) were used in observation group. Local anesthesia by lidocaine (1%) combined with midazolam (0.04 mg/kg) intravenous sedation were used in control group. HR, mean arterial pressure (MAP), heart rate (HR), breathing rate (RR), pulse oxygen saturation (SpO2) change were monitored and recorded before and after the administration of the drug, as well as at the beginning of operation, during the operation, at the end of the operation, and 5 minutes after the operation. Patients sedation degree was evaluated by Ramsay. Operation time, recovery time, the incidence of adverse reactions, the satisfaction of patients and doctors were also recorded.
RESULTSPatients had no obvious difference of intraoperative MAP, RR, SpO2, operation time and postoperative recovery time between the two groups (P > 0.05). Compared with control group, HR during the operation were decreased significantly [(64.2 +/- 8.2) bpm, P < 0.05] in observation group. In control group, there were 18 cases of patients with agitation, but they endured the operation anyway. In observation group, 24 cases of patients underwent operation without agitation. The satisfaction of patients and the operation doctors (96%) in observation group were markedly higher than that in control group (P < 0.05).
CONCLUSIONDexmedetomidine combined with remifentanil is practical and safe. The effect of reducing HR should be noticed.

Transforming growth factor-β1(TGF-β1)has become an important biological marker and therapeutic target of clinical progression of chronic kidney diseases. Sma- and Mad-related protein (Smad)is a downstream signal transduction protein of the TGF-β family. TGF-β1 activates Smad2 and Smad3 before increasing the transcription of connective tissue growth factors in the nucleus. Smad3 promotes mesangial cell proliferation,extracellular matrix accumulation,epithelial-mesenchymal transition, leading to renal fibrosis. However,Smad2 and Smad7 play a negative regulatory role by inhibiting renal fibrosis. TGF-β1 specific inhibitor (SB431542,etc.) has antifibrosis effect,most of which is in the preclinical stage. The drugs on the market that are effective for DN,such as benzodiazepines,atorvastatin, losartan,and pirfenidone,can inhibit the expression of TGF-β1,while tripterygium wilfordii,cordyceps sinensis,and berberine can delay the process of diabetic nephropathy by reducing TGF-β1 levels.

Objective To evaluate the clinical efficacy of total knee arthroplasty(TKA)in patients of osteo-arthris with valgus knee deformity after lateral meniscectomy(LMT). Methods Twenty six cases of osteo-arthris with valgus knee deformity after lateral meniscectomy were treated with total knee arthroplasty. Operation evaluations including the range of motion(ROM),the tibial and femur angle(T-F angle),Knee Society Score System(KSS)and the function score were performed as follow-up. Results The median follow-up periods was 22 months and ranged from 5 months to 3 years. The average ROM improved from 96° preoperatively to 116° at postoperatively. The average KSS improved from 22. 5 points preoperatively to 84. 4 points postoperatively. The average function score improved from 25. 5 points preoperatively to 84. 4 points postoperatively,and the average T-F angle was corrected from 22°( 13° - 31°) of valgus preoperatively to 7. 6°( 0° - 9°) of valgus postoperatively. Conclusion The TKA can provide excellent in patients undergoing osteo-arthris with valgus knee deformity after lateral meniscectomy.

The conduction of performance appraisal in the hospital is of great significance to the perfection of the appraisal system and the improvement of the managerial efficiency of the hospital. The authors suggest that in the process of establishing an appraisal system of hospital performance, it is necessary to use for reference enterprises' experience in performance appraisal and the theories of performance management. Firstly, single-faceted pursuit of economic benefits should be avoided, the establishment of an external hospital appraisal system and the establishment of an internal hospital appraisal system should be combined, and attention should be paid to the overall application of performance appraisal in performance management. Secondly, in light of their own experience in hospital management, the authors put forward the suggestion of establishing a performance appraisal system of three levels: the hospital , the department and the post. They also argue that attention should be given to the selection of comprehensive appraisal methods, continuous communication about performance, and readjustment in a timely manner.
