BACKGROUND: Astrocyte distributes the most widely in the central nerve system,but the role of astrocyte in the pathogenisis of neurodegenerative diseases is still unclear.OBJECTIVE :To investigate the effects of lipopolysaccharide (LPS) on the level of the free intracelluar calcium, the production of reactive oxygen species (ROS) and nitric oxide (NO), and the cell viability of astrocytes.DESIGN: Randomized grouping controlled experiment.SETTING: The Brain Circulation Research Laboratory, Second Affiliated Hospital of Suzhou University.MATERIALS: The experiment was carried out in the Brain Circulation Research Laboratory, Second Affiliated Hospital of Suzhou University from May 2005 to August 2005. The astrocytes were derived from the cerebral cortex of 8 Newborn SD rats aged 1-3 days provided by the Animal Experimental Center of Suzhou University. LPS was purchased from Sigma, MTT assay kit and NO assay kit were obtained from Beyotime Biotechnology.METHODS: The astrocytes were isolated and cultured using the method described by Kevin St. P. McNaught. The cells were purified by proliferation repeatedly. Astrocytes were divided into control group, LPS5, 10, 20,40 mg/L group according to different dosage of LPS added. The cell viability at 30 min and 60 min respectively was measured using MTT method.The NO accumulation in cultured cell supernatant at 30 min was assayed with Griess reagent after the treatment of LPS. Calcium and ROS accumulation in cultured astrocyte of rats stimulated by different dosage of LPS was measured at 30 min and 60 min respectively by confocal laser scan microscope (CLSM).MAIN OUTCOME MEASURES: Cell viability of astrocyte, the change of level of NO, calcium and reactive oxygen species of astrocyte.RESULTS: ① The cell viability 60 min after administration of LPS 5 mg/L,LPS 10 mg/L and LPS 20 mg/L was higher than that of control group(P ＜ 0.05). The cell viability of LPS 10 mg/L group was higher than that of LPS 5, 20 mg/L group.② NO production 30 min after LPS treatment of LPS 40 mg/L group was higher than control and the other 3 experimental groups (P ＜ 0.05 ). ③ The calcium of the LPS 5, 10 and 20 mg/L group was 200-400 times higher than that of the base state. The calcium of the LPS 40 mg/L group was 1 000 times than its baseline state; Absolute fluorescence intensity of ROS was superior than the detect range of CLSM, we could speculate that the relative fluorescence intensity of the group LPS 40 mg/L was at least 300-400 times higher than that of its base state.CONCLUSION: LPS could increase the level of the free intracelluar calcium and induce the production of ROS and NO in astrocytes.

Objective To observe the clinical efficacy of Zishen Pingchan Granules in treating non-motor symptoms (NMS) of Parkinson disease (PD). Methods A randomized, double-blind, placebo-controlled trial was used. 124 patients with PD were randomly divided into the treatment group (n=62) and the control group (n=62). Patients not yet taking Western medicine were suspended the application of Western medicine, receiving direct TCM treatment. Patients who had already taken Western medicine were added TCM on the basis of original medicine dosage and method. The treatment group was given Zishen Pingchan Granules, while the control group was treated with placebo granule, once a bag, twice a day. The treatment lasted for 12 weeks. The clinical efficacy was assessed by using unified PD rating scale (UPDRSⅡ–Ⅲ), the scale for outcomes in PD for autonomic symptoms (SCOPA-AUT), Parkinson disease sleep scale (PDSS) and dosage of levodopa. Results The UPDRSⅡ and UPDRS Ⅲscores of the treatment group and the control group after 4, 8, and 12 week of treatment had no difference at each time point compared with before treatment (P>0.05). There was no statistical significance in scores of UPDRSⅡ and UPDRSⅢ after treatment (P>0.05). Efficacy of SCOPA-AUT in treatment group after treatment was significantly better than the control group; There was statistical significance in constipation, salivation, nocturia and sweating in SCOPA-AUT between the two groups after treatment (P<0.05). Compared with before treatment, PDSS scores in treatment group after 8 and 12 weeks of treatment increased significantly (P<0.05). After 4, 8, and 12 weeks of treatment, PDSS scores in treatment group were much higher than control group (P<0.01). By comparing PDSS score in the two groups before and after treatment, it showed that treatment group had better efficacy in extending the time to sleep, reducing nocturia, nightmares, and hallucinations (P<0.05). After 12 weeks of treatment, dosage of levodopa in control group increased significantly, which treatment group was much lower than the control group (P<0.05). Conclusion Zishen Pingchan Granules can improve the autonomic dysfunctionin and sleep quality of PD patients, and can significantly reduce the dosage of levodopa.

Objective To evaluate the possibility and safety of balloon kyphoplasty for the aged osteoporotic thoracolumbar burst fractures. Methods From October 2007 to December 2012, 78 patients with aged osteoporotic thoracolumbar burst fractures were treated by balloon kyphoplasty. The inflatable balloon was inserted through pedicle of vertebal arch to make fracture reduction, then the centrum was stuffed with bone cement. The whole procedure was pinpointed and detected by C-arm x-ray machine. Results All operations were completed successfully. The lumbar and back pain of the patients relieved obviously. The quality of patients' life was significantly improved. Imaging examinations revealed that the vertebrae altitude was recovered and the kyphosis was corrected obviously. Conclusion Balloon kyphoplasty is effective to treat the aged osteoporotic thoracolumbar burst fractures. But the operation had certain risk, we must do a good job in preoperative preparation, strictly handle surgical indication and accurately operate.

Objective To evaluate the clinical efficacy of infliximab (IFX) in Crohn′s disease (CD) and its effects on mucosal healing and promoting fistula closure.Methods Between September 2007 and February 2011,relevant clinical data of CD patients treated with IFX in the Department of Gastroenterology,Ruijin Hospital were collected and the efficacy and safety of IFX were retrospectively analyzed.After IFX therapy,the efficacy evaluation included laboratory index,clinical efficacy,efficacy of fistula closure and mucosal healing.The data were analyzed using t test and Wilcoxon signed-rank test.Results A total of 22 patients were enrolled in this study,11 males and 11 females; the mean age was 29.3 years.The dosage of IFX was 5 mg/kg to 10 mg/kg at week 0,2,6to induce remission,and every 8 weeks on maintenance therapy.Of 22 patients,16 patients were active CD.One case dropped out.At week 14,of the remaining 15 cases,11 cases achieved clinical remission,two cases achieved clinically effective and two cases were ineffective.Crohn′s disease activity index (CDAI) (112±80) and ESR [(13±11) mm/1 h] of week 14 decreased compared with that of week 0 [(186±88),(21± 15) mm/1 h,P=0.04 and 0.007].Two cases of 10 patients with fistula dropped out as a result of ineffective,while eight cases had a partial response and six patients sustained response during the maintenance therapy,but no fistula closed and completely disappear.Seven patients reviewed by endoscopy after five times IFX therapy (24 weeks),after therapy the simple endoscopic score for Crohn′ s disease (SES-CD) ( 3.21 ± 2.89 ) decreased compared with that before treatment (5.86±3.02) (Z＝-2.38,P＝0.018).Eleven times of adverse events were found in nine patients,infusion reaction and respiratory tract infection were more common and no severe adverse effect was observed.Conclusions IFX can rapidly improve clinical symptoms and with good safety.The effects in mucosal healing and fistula closure may occur at early medication.

Developmental changes in children can affect drug disposition and clinical effects. A physiologically-based pharmacokinetic (PBPK) model is a mathematical model that can be used to predict blood drug concentrations in children and gain insight into age-dependent physiological differences in drug disposition impact. Pediatric PBPK (P-PBPK) models have attracted attention over the past decade. With the concerted efforts of academia, pharmaceutical companies, and regulatory agencies, there are more and more examples of pediatric clinical studies using PBPK models. Nevertheless, the number of P-PBPK models and their predictive performance still lag behind adult models. By referring to the literature, we study the process of children adapting to adult absorption, distribution, metabolism, and excretion (ADME) parameters and analyze the general principles of P-PBPK model establishment. In addition, we summarize the functions and application examples of commonly used P-PBPK modeling software to provide a basis for the rational application of modeling software.

OBJECTIVE To investigate the bacterial distribution and antibiotic resistance situation with urinary tract infection(UTI) for the guidance of rational use of antibiotics.METHODS The antibiotic resistance of clinical isolates from urinary tract infection from Mar 2005 to Jul 2006 was analyzed. RESULTS The most common pathogens in urinary tract infection were Escherichia coli(50.2%),Enterococcus(14.4%),Staphyloccus aureus(8.7%),Klebsiella pneumoniae(7.3%),and Proteus mirabilis(3.9%).E.coli,K.pneumoniae,and P.mirabilis were found to be highly resistant to ampicillin,quinolones and SMZ(70.6-100.0%).Enterococcus were highly resistant to penicillin and quinolones(81.0-96.8%).41.4% of E.coli and 31.3% of K.pneumoniae isolates produced ESBLs.HLGR-Enterococcus were 79.4%.78.9% S.aureus isolates were resistant to oxacillin.CONCLUSIONS The high antibiotic resistance of commonly encountered pathogens is a serious problem and much attention should be paid to detect pathogens and their antibiotic resistance.

Objective To study the relationship between serum Treg cells content and superoxide dismutase(SOD) level with the severity and clinical prognosis in the patients with preeclampsia.Methods Forty cases of preeclampsia in our hospital from September 2015 to September 2016 were selected as the research subjects divided into the mild preeclampsia group(25 cases) and severe preeclampsia groups(15 cases) according to the disease severity,and 20 healthy pregnant women served as the control group.The peripheral blood Treg cells and serum SOD level were compared between the two groups.The relationship between Treg cell content and serum SOD level with the disease severity and prognosis in the patients with preeclampsia was investigated.Results The systolic and diastolic blood pressure in the severe preeclampsia group were(145.3±10.6)mm Hg and(102.3±7.8)mm Hg,the occurrence rates of premature delivery,placental abruption and fetal distress were 33.3%,20.0% and 13.3% respectively,BMI before pregnancy was 25.4±1.3,which were significantly higher than those in the mild preeclampsia group and control group,while the mild preeclampsia group was higher than the control group.The Treg cell content and SOD level in the severe preeclampsia group were (2.3±0.7)×106/L and(2.6±0.7)μg/mL,which were significantly lower than those in the mild preeclampsia group and control group and which in the mild preeclampsia group were (3.4±0.6)×106/L and(4.3±0.9)μg/mL,and significantly lower than those in the control group,the differences were statistically significant(P<0.05).The Logistic regression analysis results indicated that BMI index(P=0.018),Treg cell content(P=0.024) and SOD level(P=0.029) were the independent risk factors for poor pregnancy outcome.Conclusion The peripheral blood Treg cells content and serum SOD level are closely related to poor pregnancy outcome in the patients with preeclampsia.

BACKGROUND:Now, domestic total knee arthroplasty surgeries mainly use medial parapatel ar approach, with the disadvantages of large trauma and slower recovery. The quadriceps sparing approach is more accorded with normal anatomy, which can keep the knee extension system intact. The clinical comparison between quadriceps sparing approach and medial parapatel ar approach is rare.
OBJECTIVE:To compare the early effect of total knee arthroplasty through quadriceps sparing approach and medial parapatel ar approach.
METHODS:From January 2009 to January 2010, 55 patients (70 knees) were randomly divided into quadriceps sparing approach group (n=26, 35 knees) and medial parapatel ar approach group (n=29, 35 knees). Patients in two groups received total knee arthroplasty through quadriceps sparing approach and medial parapatel ar
approach respectively. The incision length, operative time, postoperative drainage volume, additional amount of etoricoxib tablets, pain degree, straight leg raising time, start walking time, hospitalization time, range of motion of knee joint, Hospital for Special Surgery Knee Score, radiographic alignment of al components and complications were compared between two groups. Al the prostheses used in this study were the Sigma type prostheses
provided by the rotation platform of Johnson&Johnson Company.
RESULTS AND CONCLUSION:Al the patients were fol owed-up for 12-24 months without infections, deep vein thrombosis, neurovascular injury, prosthesis instability, prosthesis loosening or displacement. Position of al the
prostheses was normal in patients. The operative time in the quadriceps sparing approach group was longer than that in the medial parapatel ar approach group (P=0.00), while the incision length, postoperative drainage volume, additional
amount of etoricoxib tablets, visual analog scale, straight leg raising time, start walking time, hospitalization time, range of motion of knee joint at 3 days after replacement and Hospital for Special Surgery Knee Score in the quadriceps
sparing approach group were better than those in the medial parapatel ar approach group (P<0.05). There were no
significant differences in range of motion of knee joint at 3 days after replacement and Hospital for Special Surgery Knee Score between two groups. The early effect of total knee arthroplasty through quadriceps sparing approach is better than the medial parapatel ar approach, and there is no significant difference in prosthesis alignment between two methods.
