AIM:To investigate changes of retinal nerve fiber layer ( RNFL) thickness and macular retinal thickness in patients with early diabetic retinopathy ( DR ) and disclose the changing trends of RNFL thickness and macular retinal thickness in different stages of early DR.
METHODS:It was a clinical case control study. Through selecting 60 patients ( 120 eyes ) with early DR diagnosed with type 2 diabetes were divided into non - diabetic retinopathy (NDR) group (20 cases, 40 eyes) and mild non-proliferative diabetic retinopathy (NPDR) group (20 cases, 40eyes), moderate NPDR group (20 cases, 40 eyes) . Twenty normal patients ( 40 eyes ) were enrolled as control group. The RNFL thickness of optical nerve ( with circle scan round optic nerve head, scan diameter of 3. 45mm) and the retinal thickness of macular ( around center point with 1000μm diameter ) were measured by optical coherence tomography ( OCT ) , to compare the RNFL thickness changes of the control and early DR patients.
RESULTS:Compared with the control group, the RNFL thickness of optical disc in the inferior quadrant was descended obviously in NDR group ( P < 0. 05 ), with statistically significant difference,; there were no statistically significant difference in other quadrants ( P>0.05). In mild NPDR group, the RNFL thickness of optical disc in the mean and inferior quadrant was significantly descended than that in the NDR group. In moderate NPDR group, the RNFL thickness of optical disc in the mean, superior and inferior quadrant was statistical significance descended than that in the NDR group ( P < 0. 05 ). Compared with the NPDR group, NDR group and control group, the RNFL thickness of optical disc in each quadrant were descended significantly. There was statistically significant difference in macular retinal thickness among the NDR group, mild NPDR and moderate NPDR group ( P<0. 05), the retinal thickness was increased gradually in mild NPDR and moderate NPDR group.
CONCLUSION:With the development in the degree of early DR, RNFL thickness is gradually decreased and retinal thickness is increased, OCT can be observed qualitatively and quantitatively in DR.

ObjectiveTo observe the therapeutic effect of standing bed on orthostatic hypotension with cervical spinal cord injury. Methods36 patients with cervical spinal cord injury were divided randomly into the standing bed group and routine treatment group. The blood pressure of all patients were measured every day during rehabilitation treatment. The function of spinal cord was assessed before and after treatment.ResultsThe function of sensory and motor in the two groups were all improved, but there was no statistical difference between the two groups in the grades of spinal cord function. There were 27 patients who had orthostatic hypotension in the study. All the patients with complete spinal cord injury suffered the orthostatic hypotension. There was no improvement in blood pressure of complete spinal cord injury after treatment. In incomplete spinal cord injury patients, there was a significant improvement and the difference of blood presure between lying and standing was decreased in standing bed group after treatment (P<0.05). Compared with routine treatment group, the blood pressure in standing bed group was improved (P<0.05). Conclusions Cervical spinal cord injury could have orthostatic hypotension. Complete spinal cord injury would suffer orthostatic hypotension in different degree. The standing bed treatment could improve the orthostatic hypotension in incomplete spinal cord injury.

Ischemic stroke is a type of cerebrovascular disease with high morbidity, high mortality and high disability, which brings a huge medical burden to the society. Long non-coding RNA (lncRNA) H19 is closely associated with the pathophysiological mechanisms such as oxidative stress, inflammation, apoptosis, autophagy, and neurogenesis after ischemic stroke. It has received widespread attention in recent years. This article reviews the pathophysiological mechanism of lncRNA H19 in ischemic stroke, in order to provide new ideas for the diagnosis and treatment of ischemic stroke.

Objective To investigate the distribution and antibiotic resistance of Mycoplasma isolates from male genitourinary tract infection for rational use of antibiotics to treat Mycoplasma infections.Methods Isolates were detected using Mycoplasma IES Test Kit supplied by Yeoman Biotech (Zhuhai) Co.Ltd.Results A total of 698 strains (30.5%) of Mycoplasma was de- tected from 2 287 samples, 563 (80.7%) of which were Ureaplasma urealyticum, 26(3.7%)were Mycoplasma hominis. Both U.urea lyticum and M.hominis were identified in 109 (15.6%) specimens.U.urealyticum isolates were most suscepti- ble to josamycin, while all M.hominis isolates were susceptible to doxycyeline and minocycline, but resistant to erythromycin, roxithromycin and clarithromycin.Conclusions The best choice to treat Mycoplasma infections is josamycin, doxycycline and minocycline.The different strains of mycoplasrna may have variable susceptibility to the same kind of antibiotic.Active cul- ture, identification, and susceptibility testing of mycoplasma can provide useful data for rational use of antibiotics.

Objective To discuss the effect of C?reactive protein(CRP) levels in pregnant women with gestational metabolic syndrome ( GMS ) , and to analyze the risk factors of GMS. Methods Seventy pregnant women with GMS received regular check and hospital delivery in Yuebei People’ s Hospital Affiliated to Shantou University from May 2012 to May 2015 were selected as study group,and 100 normal pregnant women as control group. Information regarding age,gestational weeks,admission blood pressure,height and body mass index( BMI) before pregnancy was recorded. Biochemical indicators including C?reactive protein ( CRP ) , fasting plasma glu?cose(FPG),total cholesterol(TC),triglyceride(TG),low density lipoprotein(LDL?C),high density lipoprotein ( HDL?C) were tested. The correlation between CRP and GMS was calculated and the risk factors of GMS were analyzed. According to CRP levels,all pregnant women were divided into four groups to based on quartile method subjects, and the relationship of CRP levels and the incidence of GMS were evaluated between four groups. Results ( 1) The age,pre?pregnancy BMI,baseline blood pressure of GMS group were higher,gestation?al weeks was smaller than the control group(P<0. 05). (2)The CRP,FPG,TC,TG,LDL?C of women with GMS were higher than those of normal women((12. 6±32. 9) mg/L vs. (0. 39±0. 37) mg/L,(6. 04±1. 73) mmol/L vs. (4. 64±0. 29) mmol/L,(6. 77±2. 68) mmol/L vs. (4. 49±0. 57) mmol/L,(4. 54±2. 84) mmol/L vs. (2. 56±0. 90) mmol/L,(3. 69±1. 25) mmol/L vs. (2. 65±0. 51) mmol/L),and the differences were statistical?ly significant( t=2. 21,6. 72,6. 97,5. 63,6. 61;P<0. 05) ,while there was no significant difference about HDL?C level between the two groups(P>0. 05). (3)Multiple regression analysis showed that the risk factors of GMS were age,pre?pregnancy BMI,CRP,TG and TC(OR 1. 530(1. 095?2. 136),18. 427(4. 402?77. 142),4. 917 (1. 928?12. 537),2. 665(1. 379?5. 149),4. 114(2. 304?7. 348),P<0. 01),BMI and TC were the significant risk factors of GMS( P=0. 000) ,while the gestational weeks,LDL?C seemed to had less importance in identifying GMS(P>0. 05). (4)According to CRP levels,the incidence rate of GMS was 20. 69%,42. 67%,56. 06% and 72. 00%(χ2=15. 28,P=0. 002) . When CRP≥20. 0 mg/L,the incidence rate of GMS was significantly higher than the other three groups, and there were statistically differences between different groups ( P<0. 01 ) . Conclusion There are pre pregnancy overweight and / or obesity,abnormal glucose metabolism,blood pres?sure,lipid metabolism disorders such as multiple metabolic abnormalities aggregation in pregnant women with GMS. BMI and TC are the significantly risk factors for GMS. The gestational weeks,HDL?C and LDL?C have less importance in identifying GMS. The blood serum CRP is closely related to GMS and involved in the pathogenesis of GMS. THe increase of CRP level is one of the important signs of the onset and progression of GMS.
