Objective To explore possible poisonous and harmful effect of excessive iodine intake on skeleton in male rats. Methods Male rat models receiving various amounts of excessive iodine were established for 3,6, 12 months, and quantitative bone histomorphometric parameters and bone mineral density (BMD) of femur and lumbar spine( L1-1 ) were measured by means of dual-energy X-ray absorptimetry in vitro, and rats receiving normal diet were considered as control group. Results There was no significant difference in bone mineral quantity and structural parameters after feeding excessive iodine for 3 months in comparison with control group. The BMD of L1-4 was significantly increased in all animal groups when various amounts of excessive iodide was taken for 6 months (all P

Objective To analyze the clinical value of serum and cerebrospinal fluid(CSF) procalcitonin in the diagnosis of adult central nervous system(CNS) infection to provide reference for its clinical diagnosis and treatment .Methods Sixty adult patients with CNS diseases admitted to our hospital from February to December 2015 were selected as the research subjects .All patients were suspected of CNS infection at initial visiting due to suspected CNS symptoms and signs ,and the CSF pathogenic examination and separation were performed to determine the types of infected pathogenic microorganisms .Meanwhile serum and CSF procalcito-nin was detected .The detection results of CSF pathogen and procalcitonin were summarized .The detection results of CSF pathogen served as the gold standard ,serum and CSF procalcitonin> 0 .5 ng/mL as infection positive .The diagnostic test fourfold table was adopted .Then the procalcitonin detection results and CSF pathogenic microorganism detection data were inputted .The consistency of serum and CSF procalcitonin for judging CNS infection was analyzed and calculated .The sensitivity ,specificity and accuracy of serum and CSF procalcitonin detection method for detecting pathogenic microorganisms were analyzed .Results Among 60 cases ,31 cases were bacterial infection ,22 cases were viral infection and no pathogenic bacterium was detected out in 7 cases ,the positive rate was 88 .34% .In the serum procalcitonin detection :49 cases were positive and 11 cases were negative ;in CFS procalcitonin detec-tion:37 cases were positive and 23 cases were negative .The Kappa coefficients of serum procalcitonin and CFS pathogenic detection results was 0 .769 ,indicating that serum procalcitonin and CFS pathogenic detection results had higher consistency ;the Kappa coef-ficients of CSF procalcitonin and CFS pathogenic detection results was 0 .315 ,indicating that CFS procalcitonin and CFS pathogenic detection results had poor consistency .The sensitivity ,accuracy and specificity of serum procalcitonin for diagnosing CNS infection were 96 .08% ,93 .33% and 77 .78% respectively ,which of CSF procalcitonin were 73 .33% ,45 .00% and 38 .46% respectively ;se-rum procalcitonin detection had a higher clinical value in the diagnosis of adult CNS infection ,while CSF procalcitonin detection had little value .Conclusion The serum procalcitonin detection method has higher sensitivity ,accuracy and specificity for the diagnosis of adult CNS infection ,possesses a better guidance role in selecting the treatment scheme and evaluating the curative effect ,and has higher clinical value in adult patients with CNS bacterial infection .

Objective To investigate the feasibility of laparoscopically assisted anorectal pull-through in the repair of high imperforate anus. Methods Four infants (3 boys and 1 girl, age range, 1 d～90 d) with high imperforate anus entered this study. During operations, the rectum was exposed via laparoscope down to the rectourethral fistula, which was ligated and dissected out laparoscopically; and then, by way of a passage through the center of pelvic floor musculature, the rectum was exteriorized to the perineum to perform anorectal anastomosis. Results Laparoscopically assisted anorectal pull-through was successfully performed in all the 4 cases as a primary procedure. The mean duration of the laparoscopy was 71 8 min (range, 45 min～90 min) and the mean blood loss 8 3 ml (range, 5 ml～20 ml), no blood transfusion required and no intraoperative complications occurred. All patients recovered uneventfully. In 3～12 months of follow-up, 1 patient was found anal stenosis at 1 month after the operation and was cured with secondary anorectoplasty. No postoperative complications were seen in the other 3 cases. By now, all the 4 patients have normal fecal continence. Conclusions Laparoscopically assisted anorectal pull-through is an effective technique in the repair of high imperforate anus. Experience has shown that this approach offers minimally invasive wounds, excellent visualization of the rectal fistula and accurate identification of the center of pelvic floor musculature.

Objective:To discuss what impact prone position ventilation (PPV) plays in treatment of acute respiratory distress syndrom (ARDS)originating from pulmonary disease(ARDSp) and extra-pulmonary disease(ARDSexp).Methods: Retrospective case-control cohorts study. Sixty patients with ARDS were included, were classified two groups which were originated from pulmonary disease(n=30) and extra-pulmonary disease(n=30), they were ventilated in PPV. And oxygenation of 0,2,4, and 6 hours in PPV, static compliance(Cst), airway resistance(Raw) of were evaluated. The Ultrasonic Cardiac Output Monitor was applied to monitor the cardiac function.Results:At 2 hours after ventilation in ARDSexp group, PaO2/FiO2 have been improved significantly. The longer duration of PPV seemed to be associated with continuous improvement and peaks at 4 hours. In ARDSexp group PaO2/FiO2 after ventilation at 3 hours exceeds the other groups. At 4 hours after ventilation, PaO2/FiO2 of both ARDSp and ARDSexp groups of PPV have been improved than that of supine position. After ventilation for 4 hours, the RAW of ARDSp decreases dramatically and considerably below the other groups.Conclusion: PPV was a safe and effective maneuver for improving oxygenation in patients with ARDSp and ARDSexp. Both ARDSp and ARDSexp clearly appear to benefit from PPV, particularly in ARDSexp group. PPV aslo influenced haemodynamics in patients rarely.

BACKGROUND: It has been verified pharmacologically that honokiol (HL) and magnolol (ML) have distinct effects on central inhibition and muscle relaxation, and some reports prove that they can relieve morphine withdrawal symptoms in animals.OBJECTIVE: To explore the effects of HL and ML on β-endorphin (β-EP) in relieving morphine withdrawal symptoms in rats.DESIGN: Randomized controlled study.SETTING: Pharmacological Department, the Medical School of Hubei national College.PARTICIPANTS: The experiment was conducted from 13 to 29 April,2003. Among 100 adult male SD rats, 30 rats as control group were randomly divided into three subgroups: saline group, HL group and ML group with 10 in each group. The other 70 rats as morphine-dependent group were divided into normal saline group, 5, 40 and 80 mg/kg HL and ML groups with 10 in each group.METHODS: 0.2 mL normal saline, 80 mg/kg HL and 80 mg/kg ML were injected intraperitoneally into rats in control group. The dose of morphine subcutaneously injected was increased in the rats in morphine-dependent group for 6 days to establish the model of acute morphine dependence and model of natural morphine withdrawal symptoms. The last injection was performed at 9:00 on the morning of day 6, and the intraperitoneal injection was performed at 10:30 on the same morning. 0.2 mL normal saline was injected into the rats of saline group. 5, 40 and 80 mg/kg HL and 5,40 and 80 mg/kg ML were given to rats in the other six groups, respectively. Starting from 11:00, half an hour later, all natural morphine withdrawal symptoms were observed in rats within an hour.compared among rats in the 7 morphine-dependent subgroups.control groups than in normal saline group (P ＜ 0.01), and HL group had higher β-EP level than ML group (P ＜ 0.05). β-EP level was obviously lower in morphine-dependent+saline groups than in control+saline groups (P ＜ 0.01).β-EP level in morphine-dependent+5, 40 and 80 mg/kg HL groups and in morphine-dependent+5, 40 and 80 mg/kg ML groups was obviously higher Scores of natural morphine withdrawal symptoms in rats of morphine-dependent group: Scores of wetshakes, penile licking, escape attempts, and weight lost in HL and ML subgroups were obviously lower than those in saline group (P ＜ 0.01).CONCLUSION: HL and ML can markedly restrain morphine withdrawal symptoms and this restraint is related to the increase of β-EP level in the brain. HL and ML have equal inhibitory effects on morphine-dependent rats, but HL is more effective than ML in normal rats.
