ObjectiveTo evaluate the two common anesthesia techniques used in the hip joint replacement surgery (HJRS) and provide references to the most reasonable choice for them. MethodsTo undertake a retrospective study on 34 patients that received continuous epidural anesthesia(CEA) or combined intravenous and inhaled anesthesia(CIIA)respectively in HJRS. Results and Conclusions CEA had higher incidence of bone cement reaction than that of CIIA, whereas there was no significant difference in blood loss and the anesthesia efficacy between them. CIIA seemed to be easier to be performed. CIIA sounds more reasonable than CEA in HJRS although both of them are safe anesthesia techniques.

Background Compare with the lamellar laser refractive surgery,the laser slip on the surface operation is a better method in the correct of refractive error without the flap-related complications.However,whether to remain corneal epithelial flap and its influence for epithelial healing and visual restoration are still under investigation.Objective The aim of this study was to compare the short-term clinical efficacy of epipolis laser insitu keratomileusis (Epi-LASIK) and flap-free Epi-LASIK for correction of refractive error in high myopia.Methods The paired control design was adopted.Sixty eyes of consecutive 30 patients with high myopia were collected in this study.The written consent form was obtained from each patients prior to operation.Regular EpiLASIK was performed in the right eyes and the flap-free Epi-LASIK was carried out in the left eyes.Patients were followed-up for one month.The postoperative ocular irritation symptoms were scored,and the healing period of corneal epithelium and uncorrected visual acuity were examined at 1,3 and 5 days after operation.The naked visual acuity,diopter,best corrected visual acuity and the grading of haze were recorded and compared between the two groups at one month after operation.Results After surgery,the scores of corneal irritation were 3.13 ±0.43 and 3.30±0.47on the first day,showing insignificant differences between these two groups (t =- 1.54,P＞0.05 ).However,there existed statistically significant difference in the scores of corneal irritation on the third day after operation between the two groups (t =- 17.95,P＜0.01 ).The average time of corneal epithelial healing were (2.58 ±0.49 ) days in the flapfree Epi-LASIK group and ( 3.98 ±0.74) days in Epi-LASIK group with the significant difference between them (t=-11.36,P＜0.01 ).There was no statistical difference in uncorrected visual acuity in the first day (0.59±0.12 vs 0.58±0.11,t=0.39,P＞0.05),the fifth day (0.69±0.08 vs 0.67±0.09,t=0.84,P＞0.05) and 1 month (t =-1.90,P＞0.05 ).No significant difference was seen in the diopter between the two groups in 1 month after surgery (-1.03±0.45 vs -1.07 ±0.38,t =-0.31,P＞0.05 ).The eye numbers of corneal haze for 0 grade were 27 ( 90.00％ ) and over the 0.5 grade were 3 ( 10.00％ ) in flap-free Epi-LASIK group respectively,and those of corneal haze for 0 grade were 26(86.66％ ) and above the 0.5 grade were 4 (13.33％) in Epi-LASIK group respectively,showing a considerably difference between the two groups (x2 =0.0031,P＞0.05).Conclusions Both the flapfree or reserved epithelial Epi-LASIK allow the safe and effective correction of refractive error in high myopia,showing good predictability and stability in short term.Flap-free Epi-LASIK can relieve the corneal irritation symptom and accelerate the healing of corneal epithelium and recovery of visual acuity.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion for adjuvant treatment of depression in Parkinson disease and explore its mechanism. Methods: A total of 80 patients with Parkinson disease coupled with depression were randomized into an observation group and a control group, with 40 cases in each group. The control group was treated with levodopa and benserazide hydrochloride tablets and paroxetine tablets, while the observation group was treated with heat-sensitive moxibustion on the basis of the medications in the control group. The treatment course was 2 months. The Hamilton depression scale-17 (HAMD-17), unified Parkinson's disease rating scale (UPDRS) and Parkinson's disease quality of life questionnaire-39 (PDQ-39) were scored before and after the treatment, and the efficacy was evaluated after treatment. Levels of patients' serum dopamine (DA), 5-hydroxytryptamine (5-HT), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before and after the treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). The HAMD-17 scores in the two groups decreased significantly after treatment (both P<0.05), and the score in the observation group was obviously lower than that in the control group (P<0.05). The component scores and total scores of UPDRS in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (all P<0.05). The score of PDQ-39 in the observation group decreased significantly (P<0.05), and was lower than that in the control group (P<0.05). After treatment, the serum DA and 5-HT levels in the observation group increased significantly (both P<0.05) and the TNF-α and IL-6 levels decreased significantly (both P<0.05), which were statistically different from those in the control group (all P<0.05). Conclusion: Heat-sensitive moxibustion has certain auxiliary effect in treating depression in Parkinson disease, significantly improving clinical symptoms and the quality of life, which may be related to the up-regulation of DA and 5-HT levels and down-regulation of TNF-α and IL-6 levels.

OBJECTIVETo investigate the role of perindopril for prevention and treatment of glucocorticoid-induced osteoporosis (GIOP) in rabbits.

METHODSA total of 45 male New Zealand white rabbits (10 months old, weight 3.0 to 3.5 kg) were randomly divided into 3 groups involving normal control group (muscle injection of saline solution, n = 15, group NC), model group (muscle injection of dexamethasone, n = 15, group GIOP), and treatment group (muscle injection of dexamethasone combined with oral perindopril, n = 15, group GIOP+ACEI). All rabbits put to death after 12 weeks' treatment. The changes of bone mass and strength were observed and analyzed by bone histomorphology, biomechanics, metabolic bone related serological indexes and mRNA expression.

RESULTSAt 12 weeks, the analysis of bone histomorphology and biomechanics results showed that the bone mass and bone strength of group GIOP were significantly lower than that of group NC (P < 0.05); after perindopril treatment, the bone mass and bone strength of group GIOP+ACEI were higher obviously than that of group GIOP (P < 0.05). Mineralizing surface,mineral apposition rate and serum osteocalcin in group GIOP decreased than group NC; however, osteoclast number, osteoclast surface, eroded surface, and urinary deoxypyridinoline in group GIOP increased than group NC (P < 0.05); these changes were inhibited after perindopril treatment (P < 0.05). Quantitative RT-PCR revealed that after dexamethasone treatment, the ratio of SOST mRNS expression and RANKL/OPG mRNA expression obviously increased than that of group NC (P < 0.05); and Runx2 expression decreased significantly (P < 0.05); while the changes of mRNA expression were improved by perindopril treatment.

CONCLUSIONPerindopril can promote bone formation and inhibit bone resorption to deduce glucocorticoid-induced osteoporosis. This study provides a new method for prevention and treatment of GIOP.

OBJECTIVETo observe the effect of Schisandra chinensis lignans (SCL) on neuronal apoptosis and PI3K/AKT signaling pathway of rats in the cerebral ischemia injury model, and study its possible mechanism.

METHODRats were orally administered SCL high, middle and low dose groups (100, 50, 25 mg x kg(-1)) for 14 days. The cerebral ischemia injury model was established by using the suture-occluded method to rate the neurological functions. The cerebral infarction area was observed by TTC staining. The pathological changes in brain tissues were determined by HE staining. Bcl-2 and Bax expressions were detected by immunohistochemical assay. The protein expressions of p-AKT and AKT were assayed by Western blotting.

RESULTCompared with the model group, SCL high, middle and low dose groups showed reduction in the cerebral infarction area to varying degrees, improve the pathological changes in brain tissues, promote the expression of apoptin Bcl-2 and p-AKT, and inhibit the expression of apoptin Bax.

CONCLUSIONSCL shows a protective effect on rats with cerebral ischemia injury. Its mechanism may be related to the increase in p-AKT ability and antiischemic brain injury capacity and the inhibition of nerve cells.
