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.

BACKGROUND: Pathogenesy of immunoglobulin A nephropathy (IgAN) is not clear up to now. Present research has verified that the key pathogenetic pathway is abnormalities of IgA1 molecular O-glycosylation induced by decrease of β1, 3-galactosyltranferase activity in IgA1 hinge region of IgAN patients. Prophase study by the authors supposed that the key of IgAN O-glycosylation abnormality might be due to the decrease of β1, 3-galactosyltranferase specific molecular protein chaperone Cosmc in B lymphocyte of peripheral blood in IgAN patients.OBJECTIVE: To measure DNA sequence of β1, 3-galactosyltranferase specific molecular chaperone in coding region of Cosmc gene in IgAN patients, and compared with the sequence of Gene Bank.DESIGN: Case-controlled observation.SETTING: Department of Nephrology, West China Hospital, Sichuan University.PARTICIPANTS: Totally 27 IgAN patients and 10 non-IgAN patients were recruited in Department of Nephrology of West China Hospital of Sichuan University from November 2005 to August 2006, and five normal controls were included in this study. All the subjects knew the fact and agreed to participate in the experiment.METHODS: The experiment was performed at the State Key Laboratory of Biotherapy of Sichuan University. 2 mL peripheral venous blood of all the samples were taken into heparin sodium anticoagulated tubes, from which total genomic DNA were extracted by phenol/chloroform precipitation method. Concentration of DNA was determined by ultraviolet spectrophotometer. The polymerase chain reaction (PCR) was used to amplify the coding region of β1, 3-galactosyltranferase specific molecular chaperone Cosmc gene in all the subjects and direct sequencing was done in PCR products of each subjects. The results of all the sequencing were compared with Gene Bank one by one.MAIN OUTCOME MEASURES: Amplification findings and sequencing of coding region of β1, 3-galactosyltranferase specific molecular chaperone Cosmc gene by PCR.RESULTS: ①Coding region of Cosmc gene located at 257-1 213, and amplified Cosmc gene was 1 247 bp. ②The sequence of Cosmc gene coding region was similar in IgAN patients, non-IgAN patients and normal controls, and no difference of gene sequence was noticed in all the result sequences as compared with the Gene Bank registered sequence.CONCLUSION: No abnormal sequence is found in coding region of Cosmc gene in IgAN patients, suggesting that this coding region probably is not associated with the abnormalities of IgA1 O-glycosylation in IgAN.

In this paper, water content, mineral element and active ingredient concentration on fifteen Inonotus obliquus which comes from all over the world were studied. In the aspect of water content, the free water content of Finnish birch was the highest, reaching 77.21%, significantly better than that of other strains. The free water content of JL04 is the lowest, only 54.6%. The bound water content of HLJ01 which from Heilongjiang is the highest, reaching 10. 74% , significant differences among other strains. The bound water content of Birch Russia was the lowest. In the aspect of mineral element, the calcium content of NBRC9788 was the high- est (3.49 mg · g(-1)), significantly better than other strains. The second was Finnish birch. The lowest was CX02. The phosphorus content of NBRC9788 was the highest (210.12 μg · g(-1)), significantly superior to other strains. The lowest was JL04. In the aspect of active ingredient concentration, the triterpenoids content of HLJ01 was highest (23.7 mg · g(-1)), significantly better than other strains. It was good strains for biological products research and development and then was Finnish birch. The betulin content of MAFF420165 and MAFF420308 was low, they were not suitable for production. The polysaccharide content of Finnish birch was the highest (9.7%), significantly better than the other strains, it is one of the most ideal and good strains to develop polysaccharide. The polysaccharide content from MAFF420308 and MAFF420256 was 1.2%, lower than other strains. We suggest that avoid using these strains in the study of polysaccharide product development.

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.

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.
