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 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.

Methods 60 cases of patients with ischemic cerebrovascular disease admitted in our hospital from January 2016 to January 2017, and were randomly divided into control group and observation group, 30 cases in each group. The control group were treated by endovascular treatment, the observation group were treated with simple drug treatment, the two groups of patients treated for 6 months, 12 months to improve blood flow, the incidence of cerebrovascular events, mortality, prognosis Quality of life scores as a comparison basis.Results The patients in the observation group were treated for 6 months, 12 months after the blood flow improved superior to the patients in the control group (P<0.05); the patients in the observation group were treated for 6 months, 12 months of cerebrovascular disease incidence rate lower than that of the control group (P<0.05); the observation group after 6 months treatment and mortality of patients in the control group had no significant difference; the patients in the observation group after 12 months of treatment the mortality rate lower than that of the control group (P<0.05). The patients in the observation group survival quality scores were excellent in the control group (P<0.05). Conclusion The study proves that, in the treatment of patients with ischemic cerebrovascular disease in the treatment can effectively improve the treatment effect of endovascular intervention, improve the blood flow status of patients, reduce the events in patients with cerebrovascular disease incidence and mortality.

Objective To analyze the mechanism of pigment epithelium?derived factor(PEDF)regulation in lung cancer cell proliferation and migration by vascular endothelial growth factor(VEGF). Methods VEGF expression was observed after overexpression or silencing of PEDF. Proliferation and migration were analyzed by MTT and transwell assays. Real?time PCR and Western blotting were performed to investigate the mechanism underlying PEDF regulation of the VEGF/SRC/FAK pathways. Results PEDF could inhibit the proliferation and migration of A549 cells by VEGF. Conclusion PEDF can be considered as a potential therapeutic target for lung cancer.

Objective To investigate the effect of transitional care of physical and mental health of the thoracic spinal cord injury and paraplegic patients discharged on its recovery. Methods Randomized controlled analysis of patients in Spine and Spinal Cord Injury Surgery between June 2014 to October 2015, a total of 65 patients with thoracic spinal cord injury and paraplegic were studied, according to hospital mantissa odd and even numbers divided into observation group (35 cases) and control group (30 cases). The observation group was instituted to extending posthospital care, not the control group. The self-care ability and psychological state were evaluated by Function Independent Measure (FIM), Hamilton Anxiety Scale(HAMA), Hamilton Depression Scale (HAMD)within discharge and in 3 months. And the incidence of complications between the two groups were compared. Results At discharge, the difference of FIM, HAMA, HAMD score between the observation group and the control group was not statistically significant (P>0.05). Discharged after 3 months, the score of FIM, HAMA, HAMD in observation group was(72.35 ± 4.35),(4.80 ± 4.50),(12.13 ± 7.25)points, (63.95 ± 5.02),(10.15 ± 4.91), (19.48 ± 8.31)points in control group. The difference between the two groups was statistically significant (t=-4.798, 3.524, 3.110, P<0.01). There was no significant difference in the incidence of pulmonary infection and blood clots between two groups (P > 0.05); The incidence of urinary tract infection, pressure ulcers, constipation were 8.57% (3/35), 5.71% (2/35), 17.14% (6/35) in observation group, 40.00% (12/30), 33.33%(10/30), 63.33%(19/30) in control group, there were significant differences between, two groups (χ2= 4.324, 4.219, 5.337, P < 0.05). Conclusions Transitional care can significantly improve the psychological state of patients with thoracic spinal cord injury and paraplegia discharged, reduce the incidence of complications and improve quality of life.
