They were randomly divided into three groups: the first group was infected by E\^g . in the periodontal tissue, the second group was infected by symbiotic bacteria (s.b.),and the third group was given physiological saline as control.Observation on the periodontal inflammation was made for each group of rats, and the purulent secretion from periodontal abscess was examined for living pathogens.\ Results The incidence of periodontal diseases in rats infected by E\^g . was higher than that of symbiotic bacteria group and that of control ( P

Objective To compare the surgical outcomes between microsurgery lumbar discectomy and microendoscopic discectomy for lumbar disc herniation. Methods A prospective study was conducted on the surgical procedures for lumbar disc herniation.The target of our study was a group of 33 patients who underwent surgery by microsurgery lumbar discectomy(MSLD group)and 36 patients who underwent surgery by microendoscopic discectomy(MED group).The items investigated were the operation time,amount of bleeding,duration of hospitalization,pre-and postoperative scores based on judgment criteria for treatment of lumbar spine disorders established by the Japanese Orthopaedic Association score,visual analog scales (VAS,0 to 10) for lumbago and sciatica before surgery and at discharge,perioperative complications.Results The mean duration of follow-up was 2 years and 2 months (11 months to 4 years).There were no significant differences between the 2 surgical procedures in the frequency of the pre-and postoperative Japanese Orthopaedic Association scores or postoperative VAS for lumbar pain and sciatica,operation time and duration of hospitalization. Statistically significant differences were observed in amount of bleeding and operation time,but the differences were not large, and may not have been clinically significant.Conclusion Both microsurgery lumbar discectomy and microendoscopic discectomy are appropriate for lumbar disc herniation.

Objective To explore the role of glutamate in inducing cortical neuron damage in newborn rats.Methods The model of damage induced by glutamate was established on cultured cortical neurons in newborn rats with primary cultivation technique.To evaluate the severity of neuron injury, the changes of morphology were observed by inverted microscopy, the cell viability and rate of LDH releasing from neuron were detected by MTT assay and biochemical method,respectively;the rate of neuronal apoptosis was measured by flow cytometer system.Results Under the inverted microscopy, neurons showed obvious toxic damage in glutamate treatment group. Compared with controls,the cell viability significantly decreased (t=4.58 P

Objective To investigate the role of chemokine ligand 2 (CCL2) in the spinal cord expression in a rat model of tibia bone cancer pain.Methods Eighty-four female SD rats weighing 160-180 g were randomly divided into 3 groups ( n =28):control group (group C),sham operation group (group S) and tibia bone cancer pain group (group P).Tibia bone cancer pain was induced by intra-tibial inoculation of Walker-256 breast cancer cells.Paw withdral threshold to mechanical stimulation (MWT) was measured with von Frey filaments at 1 d before and at 1,3,7,10,14 and 21 d after inoculation.Six rats in each group were sacrificed after the measurement of MWT at 1 d before inoculation and at 7,14 and 21 d after inoculation.Lumbar 4-6 segments of the spinal cord were removed for determination of the expression of CCL2 by ELISA.The coexpression of CCL2 with Iba-1 (a specific marker of microglia),GFAP(a specific marker of astrocyte) and NeuN (a specific marker of neuron) was determined by double immunofluorescence assay after the measurement of MWT at 14 d after inoculation in group P.Results Compared with groups C and S,MWT was significantly decreased from 7 d to 21 d after inoculation,the expressive of CCI-2 in the spinal cord up-regulated at 7,14 and 21 d after inoculation in group P ( P ＜ 0.05).CCL2 was expressed in the microglia and astrocyte but not in neuron in the spinal cord dorsal horn in a rat model of tibia bone cancer pain.Conclusion Release of CCL2 from microglia and astrocytes in the spinal cord was involved in mechanical hyperalgesia in a rat model of tibia bone cancer pain.

Inosiplex is a compound formulation composed of inosine and p-acetaminobenzoic acid (PABA) salt of N,N-dimethylamino-2-propanol (DIP). This study was to investigate the clinical plasma pharmacokinetic properties of DIP and PABA after single and multiple oral doses of inosiplex tablets in healthy Chinese volunteers. The established LC/MS/MS method for plasma DIP determination had a linear range of 0.02-10 mg/mL, and the HPLC method for plasma PABA determination had a linear range of 0.05-40 mg/mL. Linear pharmacokinetic characteristics were found with single oral doses of 0.5, 1.0 and 2.0 g. No obvious accumulation effects were observed for DIP and PABA.

Objective To examine mycological profile of eryptococcal meningitis in patients with non-acquired immune deficiency syndrome (AIDS) during treatment and follow-up so that to support clinical therapy. Methods Data of 28 cuhure-confirmed cryptoeoccal meningitis patients with non-AIDS were retrospectively analyzed. Fungat smear, count, culture and latex agglutination test of cerebrospinal fluid (CSF) were done during treatment and follow-up. Initial treatment included intravenous amphotericin B plus oral flucytosine or f;uconazole for at least 6 weeks, and consolidation treatment included oral fluconazole and (or) itraeonazole for at least 2 months. All 28 patients were cured. The data were analyzed by rank-sum test. Results The positive rate of CSF fungal smear was 92.9% before treatment and gradually decreased, and the fungal count was significantly reduced over time after treatment. While fungal smears of some patients were still positive after initial treatment. Fungal growth time in culture was gradually extended, and fungal culture turned to be negative in all patients after 2 weeks of treatment. The positive rate of latex agglutination test of CSF was 100%. Cryptococcal antigen titer decreased steadily after treatment, which was not correlated with the decrease of fungal count. Conclusion Mycological tests of patients with eryptococcal meningitis should be interpreted comprehensively during treatment, and result of each test should be specifically analyzed.

Objectives To analyze the spectrum of renal diseases associated with monoclonal gammopathy and unrelated renal diseases.Methods Hospitalized patients in Peking Union Medical College Hospital who underwent renal biopsy between January,2013 and December,2015.They had monoclonal gammopathy on serum protein electrophoresis (SPE),serum immunofixation electrophoresis (IFE),urine IFE and/or serum free light chain (FLC).64 patients met the inclusion criteria and were classified as monoclonal gammopathy of renal significance (MGRS) (n=36),monoclonal gammopathy of undetermined significance (MGUS) (n=17) and hematologic malignancy (n=11).Results Renal lesions in MGRS subgroup included light chain amyloidosis (n=28,77.8％),light chain deposition disease (n=7,19.4％),and fibrillary glomerulopathy (n=l,2.8％).eGFR in light chain amyloidosis subgroup differed significantly,compared with light chain deposition disease [eGFR 93 ml· min-1 · (1.73m2)-1 vs 28 ml· min-1 · (1.73 m2) 1,P ＜ 0.01],as well as HTN incidence (35.7％ vs 100.0％,P ＜ 0.01).Renal diseases in MGUS subgroup included membranous nephropathy (n=10,58.8％),focal segmental glomerulosclerosis (n=3,17.6％),diabetic glomerulopathy (n=l,5.9％),Henoch-Schonlein purpura nephritis (n=l,5.9％),anti-glomerular basement membrane disease concurrent with membranous nephropathy (n=l,5.9％) and glomerulomegaly (n=l,5.9％).Various renal lesions related/unrelated to hematologic malignancy were seen in third subgroup,including light chain cast nephropathy (n=3,27.3％),tubulo-interstitial lesions (n=2,18.2％),light chain amyloidosis (n=1,9.1％),light chain deposition disease(n=1,9.1％),IgA nephropathy (n=1,9.1％),mesangial proliferative glomerulonephritis (n=l,9.1％),endocapillary proliferative glomerulonephritis (n=1,9.1％) and acute tubular necrosis (n=1,9.1％).Positive rates of SPE,serun IFE and urine IFE in MGRS subgroup were 40.6％,52.8％ and 69.4％,respectively.Positive rates of SPE,serum IFE and urine IFE in MGUS subgroup were 68.8％,100.0％ and 37.5％,respectively.Positive rates of SPE,serum IFE and urine IFE in hematologic malignancy subgroup were 54.5％,72.7％ and 81.8％ respectively.MGRS and MGUS subgroups differed significantly in positive rate of serum IFE (P ＜ 0.001).Abnormal rates of serum FLC ratio in above three subgroups were 83.3％,17.6％ and 90.9％,respectively,with that in MGUS group being significantly lower than the rates in other two groups (P ＜ 0.001,respectively).Conclusions The significance of monoclonal gammopathy in patients with renal disease should be evaluated by other clinical data,as well as renal pathology.
