Objective:To explore the relationship between expressions of guococorticoid receptor(GR)? and ? mRNA in peripheral blood mononuclear cell(PBMC) of patients with polymyositis/dermatomyositis(PM/DM) and the glucocorticoid(GC) efficacy.Methods:Reverse transcription-polymerase chain reaction(RT-PCR) was used to semiquantite the expressions of GR? and ? mRNA in PBMC of 18 cases of PM/DM patients sensitive to GC,10 cases of PM/DM patients resistant to GC and 20 cases of health blood donors.The levels of cortisol in sera of PM/DM patients and of health donors were detected using radioimmunoassay.Results:There was no significant difference in the levels of seral cortisol among PM/DM patients sensitive to GC, resistant to GC and the health donors.The expressions of GR? mRNA in PBMC from PM/DM patients either sensitive to GC or resistant to GC were significantly lower those that of the normal control. Moreover,the expression of GR? mRNA in PBMC of PM/DM patients resistant to GC was significantly lower than that of patients sensitive to GC. While the expression of GR? mRNA in PBMC of PM/DM patients was significantly higher than that of the normal control,there was no significant difference of the expression of GR? mRNA between PM/DM patients sensitive and resistant to GC.Conclusion:The lower expression of GR? mRNA in PM/DM patients may be related to resistance to GC therapy,whereas there is no significant role of the expression level of GR? mRNA.

Objective To compare the accuracy of BIS and skin conductance (SC) for assessment of the depth of sedation induced by target-controlled infusion (TCI) of propofol. Methods Thirty ASA Ⅰ orⅡpatients aged 21-56 yr weighing 52-85 kg undergoing orthopedic operation on the lower limb under epidural anesthesia were enrolled in this study.After the onset of epidural anesthesia, TCI of propofol was started at an initial target plasma concentration (Cp) of 0.8 μg/ml. Th Cp was increased by 0.5-0.8 μg/ml every 3 min until OAA/S score=1. OAA/S score, BIS and SC values were recorded, SC change value (△SC) was calculated. Spearman rank-order correlation, receiver operating characteristic curve (area under curve AUC was calculated) and logistic regression were used to analyze the relationship of OAA/S score to BIS and △SC.Results BIS and △SC were significantly correlated with OAA/S scores (r were 0.920 and-0.859 respectively). The AUC of △SC (0.919, 0.946) was significantly better correlated with OAA/S score (5→4, 4→3) than that of BIS (0.761, 0.507), while BIS was better correlated (0.781, 0.959) with OAA/S score (3→2, 2→1) than ASC (0.577, 0.630). Logistic regression correctly predicted loss of consciousness. The accuracy of prediction was 93% for BIS and 82% for △SC. Conclusion The accuracy of SC for assessment of the depth of sedation induced by propofol TCI ishigher than that of BIS before loss of consciousness,while lower than that of BIS after loss of consciousness. BIS is more accurate in monitoring the loss of consciousness.

Objective To detect the expressions of vascular endothelial growth factor(VEGF) and Periostin in patients with diabetic retinopathy (DR),and to explore its chnical significance.Methods A total of 52 patients with DR (DR group),36 non-DR diabetic patients (non-DR group) and 30 healthy person (normal control group) were enrolled.The 52 cases of DR patients were divided into non-proliferative DR (PDR) group (non-PDR group,24 cases) and PDR group (28 cases).The expressions of serum VEGF and Periostin were detected with enzyme-linked immunosorbent assay analysis.Results The serum expressions of VEGF and Periostin were significantly higher in non-DR group and DR group than those in normal control group [(122.63 ±28.74),(163.58 ±42.37) mg/L vs.(91.53 ± 19.58) mg/L,(110.15 ±32.62),(146.51 ± 41.74) mg/L vs.(82.26 ± 21.17) mg/L,P ＜ 0.05 or ＜ 0.01].The serum expressions of VEGF and Periostin were significantly higher in DR group than those in non-DR group (P ＜0.05).The serum expressions of VEGF and Periostin were significantly higher in PDR group than those in non-PDR group [(174.15 ±47.31) mg/L vs.(147.66 ±38.25) mag/L,(160.31 ±46.43) mg/L vs.(132.14 ±35.62)mg/L,P ＜ 0.05].The serum expression of VEGF was positively related with Periostin (r =0.415,P ＜ 0.01).Conclusion The high-expressions of VEGF and Periostin are found in DR patients,and which maybe play a key role in the early diagnosis and assessment the progression of DR patients.

Objective To investigate the effect of rocuronium on spectral entropy during induction of general anesthesia in patients of Uygur nstionality. Methods Forty ASA Ⅰ or Ⅱ patients (Uygur nationality) of both sexes, aged 20-50 yr, weighing 45-70 kg, undergoing elective surgery under general anesthesia, were divided into 2 groups ( n = 20 each): normal saline (NS) group and rocuronium group (group R). Anesthesia was induced with target-controlled infusion of propofol. The initial target plasma concentration wan net at 2 μg/ml. The concentration wan then increased by 0.5 μg/ml every 4 min until response entropy (RE) was decreased to 45 and maintained for 4 min. When the plasma concentration was equal to the effect-site concentration, iv rocuronium 0.6 mg/kg was injected in group R, while group NS received the equal volume of NS instead. Fentanyl 3 μg/kg was injected intravenously at 3 min after recuronium administration. The patients were tracheal intubated and mechanically ventilated. State entropy (SE) and RE were recorded immediately before induction (baseline, To), before rocuronium administration (T1), 2 main after rocuronium administration (T2) and at 0, 1, 2 and 3 min after intubation (T3-6). The difference between RE and SE wan calculated. Results The RE value at T3 and T4 and the difference between RE and SE at T2.5 were significantly lower in group R than in group NS ( P ＜ 0.05). Conclusion Rocuronium can decrease the RE value and degree of increase in the difference between RE and SE during induction of general anesthesia in patients of Uygur nationality, which may affect the accuracy of spectral entropy in monitoring the depth of anesthesia.

BACKGROUND:As for patients with one-side backleg pain who were candidates for surgery treatment of lumbar intervertebral disc herniation, the common treatment includes lumbar vertebral plate opening and decompression, and laminectomy in combination with compression and bilateral pedicle screw fixation. However, these therapeutic approaches are not satisfactory. OBJECTIVE:To explore the feasibility and efficiency of single-side lumbar interbody fusion and unilateral pedicle screw fixation for treatment of lumbar intervertebral disc herniation patients with one-side backleg pain. METHODS:Forty patients with single-side lumbar disc herniation, suffering from unilateral backleg pain, were recruited from Shihezi People’s Hospital, China and were treated with single-side lumbar interbody fusion and unilateral pedicle screw internal fixation. The neurological function of patients was assayed using Japanese Orthopaedic Association score system before and after treatment, the improvement rate and excellent/good rate were calculated. Suk criterion was used to determine fusion status. RESULTS AND CONCLUSION:The mean fol ow-up period for 40 patients was ranging from 6 months to 60 months. Al incisions healed wel , with no infection. The Japanese Orthopaedic Association score after 6 months of treatment was significantly higher than that before treatment (P<0.05), with the excellent and good rate up to 88%. According to Suk criterion, 38 patients achieved bone graft fusion or possible fusion, with interbody fusion rate 95%, as revealed by radiographic and CT evidence. The remaining two patients were detected fusion at 9 months after treatment. Our findings indicate that, single-cage lumbar interbody fusion combined with single-side pedicle screw fixation is the feasible surgical technique and provides satisfactory effects in treating single-side lumbar disc herniation.

Purpose　To observe exogenous epidermal growth factor (EGF) influence upon sensory neurons axotomy-induced and change ultra-structure of sensory.　Methods　Eighteen male Sprague-Dawely rats weighing 180-200 g(8-9 weeks of age)were randomly divided into two groups.One as control,the other was treated with EGF.Sciatic nerve injury model was set up by transecting left side sciatic nerve at 0.5 cm away from performed muscle.The proximal stump of sciatic nerve was ligated to inhibit nerve regeneration.Then 5 μl of normal saline in the control groups and an equal volume of EGF solution (containing 10 μg EGF) in the EGF treated groups were injected into the proximal of ligated nerve.The rats were sacrificed in 7,14,28 days of operative intervals respectively and transcardialy perfused with 4% para-fromaladehyde.The L5 dorsal root ganglion(DRG) were harvested.Eletromicroscope technique was used to observe the changes of L5 DRG sensory neurons axotomy-induced.　Results　A series of changes happened in the control group.The size of the nucles decreased.Nucleoplasm was scattered.The nucleolus was pale.Edema,loss of crest and matrix was found in the mitochondria. Satellite cells detached from the soma.The ultrastructure of L5 DRG sensory neurons in EGF groups get near to normal following nerve injury.　Conclusions　EGF could protect sensory neurons.

Objective To investigate the correlation between uric acid level and macrovascular disease in type 2 diabetic patients.Methods Sixty type 2 diabetic patients with lower limb atherosclerosis of carotid artery were randomly selected in study group who hospitalized in the First Hospital of Zibo from Mar.to Feb.2012.Sixty type 2 diabetes mellitus(T2DM) without carotid and lower limb athemsclerosis were served as control group.The blood pressure,blood lipid,blood glucose and other biochemical indexes,including blood uric acid,serum insulin (FNS),fasting blood glucose (FPG),apolipoprotein a (LP (a)),apolipoprotein A1,B (APO-A1,APO-B),glycosylated hemoglobin (HbA1c),high density lipoprotein cholesterol (HDL-C),low density lipopmtein cholesterol (LDL-C),triacylglycerol (TG) and total cholesterol (TC) were measured and determined.Results There was no significant difference in terms of blood pressure,blood lipid levels,APO-A1,APO-B,HbA1C,FNS and FPG in study group patiems (P ＞ 0.05).The level LP(a) in study group was (0.4 ± 0.2) g/L,significantly higher than that in control group ((0.2 ± 0.2) g/L; t =3.842,P ＜ 0.01).The blood uric acid level in study group was (362.3 ± 112.8)mmol/L,significantly higher than that of the control group((284.8 ±68.6)mmol/L;t =3.188,P＜0.01).Conclusion Uric acid and LP(a) are involved in the oocurrence and development of athemsclemsis,which is close related to the development of type 2 diabetic macmangiopathy.Therefore,in the process of preventing type 2 diabetes with macroangiopathy,we should pay attention to uric acid and LP (a) of the patient beside effective control of blood glucose,blood pressure,blood lipid level.
