PPAR ? is one of the three isoforms of peroxisome proliferator-activated receptors (PPARs) which are essential regulators of lipid storage and metabolism. PPAR ? primarily stimulats lipid metabolism and energy uncoupling in adipocytes and myocytes as well as involvs in the onset and development of many diseases. As the target of medicines, PPAR ? agonists may be powerful drugs for epidermal wound and metabolic syndrome X.

AIM: To observe the interocular symmetry of primary angle-closure suspects` (PACS) parameters using IOL Master.METHODS: A cross-sectional observational study.Totally 112 eyes from 56 subjects were enrolled to detect the difference of the bilateral axial length (AL), anterior chamber depth (ACD) and white to white distance(WTW), and to evaluate the correlation between the interocular differences of △AL, △ACD and △WTW and age, gender.RESULTS: All the parameters were analyzed by paired-samples t test and there were no significant interocular difference (P>0.05).There was no relation of ΔAL,ΔACD and ΔWTW with age and gender.CONCLUSION: Interocular symmetry of parameters by IOL Master was observed in PACS, and we found that the symmetry would not be altered when the age and gender had changed.

Objective To observe the effects of intensive insulin therapy on C-reactive protein (CRP) ,interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α ) in the patients of critical illness complicated with hyperglycemia and its incidence of side effect. Methods Two hundred and nine patients of critical illness complicated with hyperglycemia were randomly divided into intensive insulin therapy group (106 patients,blood glucose maintained at a level of 4.4-6.1 mmol/L) and conventional insulin therapy group ( 103 patients, blood glucose maintained at a level of 9.0-11.1 mmol/L). Serum levels of CRP,TNF- α and IL-6 were determined on 0,24,48,72 h respectively after ICU admission. Results The levels of blood glucose of both groups reached the target level. The incidence rates of the hypoglycemia had no significant difference between two groups [6.60 % (7/106) vs. 4.76% ( 3/63 ),P > 0.05]. After 72 h treatment, serum level of CRP in intensive insulin therapy group was significantly lower than that in conventional insulin therapy group (P < 0.05 ). After 24,48 and 72 h treatment, serum level of IL-6 in intensive insulin therapy group was significantly lower than that in conventional insulin therapy group (P < 0.05 ). After 48 and 72 h treatment, serum level of TNF-αin intensive insulin therapy group was significantly lower than that in conventional insulin therapy group (P < 0.05). Conclusion Intensive insulin therapy can significantly decrease the levels of non-specific inflammatory factors in patients of critical illness complicated with hyperglycemia, which brings beneficial effect to the patients.

Objective To investigate the effects of morphine dependence and withdrawal on neurosteroids and amino acid transmitters of rat amygdala. Methods Morphine dependence was induced by pretreatment with increasing doses of morphine for 7 days. Withdrawal was precipitated by naloxone (2mg/kg). Withdrawal syndromes were observed and scored. After decapitation, amygdala was dissected out. Nomadic and conjugated neurosteroids were extracted using liquid-liquid extraction and solid phase extraction. Concentrations of neurosteroids including dehydroepiandrosterone (DHEA), pregnenolone (PREG), allopregnanolone (AP), dehydroepiandrosterone sulfate (DHEAS) and pregnenolone sulfate (PREGS) were detected with HPLC-MS. Concentrations of glycine (GLY), glutamate (GLU) and gamma-aminobutyric acid (GABA) were quantitated by HPLC-ECD with pre-column OPA derivatization. Results Compared with saline control, the DHEA level in rat amygdala of morphine dependent group decreased by 33% (P＜0.01). Compared with naloxone control, the PREG and AP levels in rat amygdala of morphine withdrawal group increased by 45% (P＜0.05) and 42% (P＜0.05) respectively; the GABA level decreased by 18% (P＜0.01). Compared with morphine dependent group, the PREG and PREGS levels in rat amygdala of morphine withdrawal group increased by 60% and 40% respectively (P＜0.05); the glycine level decreased by 14% (P＜0.05). Conclusion The DHEA in rat amygdala may play a role in the development of morphine dependence but not involved in the manifestation of withdrawal symptoms. Other neurosteroids (including PREG, AP and PREGS) in rat amygdala seem to be involved in withdrawal but not in dependence. The synthesis and release of inhibitory amino acids in amygdala were depressed when withdrawal was precipitated by naloxone. The results suggest that different changes of neurosteroids and amino acids exist in stages of morphine dependence and withdrawal.

Objective To evaluate the value of 18F-FDG PET/CT in histological grading and staging of follicular lymphoma (FL) and prediction of prognosis after first-line treatment.Methods From May 2007 to April 2013,24 patients (11 males,13 females; median age 55 years) with histopathological proof of FL were retrospectively studied.All patients were evaluated by 18F-FDG PET/CT before the first-line treatment and were divided into indolent FL and aggressive FL according to their histological grades and clinical stages.The sensitivity,specificity and SUVmax were calculated.Analysis of variance of factorial design was used to analyze the data.Within the same study period,18F-FDG PET/CT was also performed in 16 FL patients (9 males,7 females; median age 50.5 years) after first-line treatment (7/16 patients belonged to the aforementioned group with pretreatment PET/CT performed) ; and they were then divided into PET/CTpositive and PET/CT-negative groups.All 16 patients were followed for 6-49 months to evaluate the prognosis.The rates of overall survival (OS) and progression-free survival (PFS) were calculated.Results (1)The sensitivities of PET/CT in indolent and aggressive FL were 92.3％ (12/13) and 100％ (11/11),respectively.The SUVmax was 5.26± 1.70 vs 9.54±5.09 (F=5.196,P＜0.05).(2) According to PET/CT,3patients(12.5％,3/24) were upstaged from Ⅰ-Ⅱ to Ⅲ-Ⅳ,and 2 patients(8.3％,2/24) were downstaged from Ⅲ-Ⅳ to Ⅰ-Ⅱ.The SUVmax of stage Ⅰ-Ⅱ and Ⅲ-Ⅳ FL was 5.22±2.92 and 8.04±4.46(F=2.904,P＞0.05).(3)For the 16 FL patients with PET/CT after first-line treatment,the negative and positive groups had different OS and PFS.The 6-month OS,1-year OS and 3-year OS were 100％(13/13),9/9,4/5,respectively for the negative group,and 2/3,2/3,1/2,respectively for the positive group; while the corresponding 6-month PFS,1-year PFS and 3-year PFS were 92.3 ％ (12/13),8/9,3/5 and 2/3,0/3,0/2,respectively.Conclusions 18F-FDG PET/CT is valuable in the evaluation of histological grading and clinical staging of FL patients and in the prediction of prognosis after fist-line treatment.

Calcineurin inhibitors,such as cyclosporin A and tacroli mus,are widely-used i mmuno-suppressive drugs clinically.However,renal toxicity,hyperglycae mia and other side-effects can occur over long-term use.Isolation of novel calcineurin inhibitors fro m medicinal plants in recent years has pro-vided a new approach to the development of new immunosuppressive drugs with high efficiency and low toxicity.Recnt studies have shown that medicinal plant extracts, such as isogarcinol, quercetin, kae mpferol,phenylethanoid glycosides,ere mophilane sesquiterpenes A and B,pisiferdiol,as well as extracts fro m Smilax china L and Jasminum humile L,have obvious inhibitory effect on calcineurin.

Objective To evaluate the efficacy and tolerability of midodrine (Gutron) in female patients with stress incontinence. Methods A randomized,double-blind,parallel,placebo-controlled,multicentric study was carried out.136 female patients with stress incontinence.68 cases in study group received Gutron (2.5 mg,thrice daily) for a course of 4 weeks.68 cases in control group received placebo in the same manner. Results 129 cases completed the treatment.The mean quantity of incontinent urine decreased by 9.9 g in those receiving Gutron ( n =66) and by 3.1 g in placebo ( n =63),respectively ( P 0.05). Conclusions Midodrine hydrochloride at the dose of 2.5 mg thrice daily has greater efficacy on female patients with stress incontinence than placebo, and the tolerability of midodrine was equivalent to that of placebo.
