20 patients with myofascial pain dysfunction syndrome(MPDS)were were treated by NTI-tss splint only during night for 2 months.After treatment,VAS decreased(P <0.01)and active maximum mouth opening degree increased(P <0.01).NTI-tss splint is ef-fective in the treatment of MPDS.Its side effect needs to be further observed.

Vertigo is a kind of patients' subjective feelings. The severity of vertigo is closely related to many factors. But we are short of a well accepted quantitative evaluation method capable of accurately and comprehensively evaluating vertigo in clinics. Reducing the onset of vertigo, enhancing the re- covery of equilibrium function, and improving the quality of life of vertigo patients should be taken as the focus of evaluating therapeutic effects. As for establishing a Chinese medical effectiveness evaluation system for vertigo, we believe we should distinguish different "diseases". We could roughly identify it as systemic vertigo and non-systemic vertigo. For systemic vertigo, the efficacy of vertigo could be comprehensively evaluated by UCLA vertigo questionnaire or dizziness handicap inventory combined with equilibrium function testing indices. But for non-systemic vertigo, the efficacy of vertigo could be comprehensively evaluated by taking UCLA vertigo questionnaire or dizziness handicap inventory as main efficacy indices. Secondly, we should analyze different reasons for vertigo, choose symptoms and signs in line with vertigo features as well as with Chinese medical theories, and formulate corresponding syndrome effectiveness standards according to different diseases. We should not simply take syndrome diagnosis standards as efficacy evaluation standards.

Objective To find out the consumption situation of iodized salt in Baotou, identify problems and take appropriate intervention measures, and to provide scientific basis for further consolidating the results of control measures, strengthening and improving the sustainable elimination of iodine deficiency disorders. Methods Three batches of each quarter, 54 salt samples were sampled in Donghe wholesale division and Qingkun wholesale division in Baotou city salt company during 2008 - 2010; each place of Damaoqi, Baiyun district, and Qingshan district were divided into five sampling areas according to the direction of east, west, south, north, and central position, one school was selected in each district, 30 students aged 8 to 10 from each school were selected, and home salt samples were taken, and salt iodine was tested by direct titration(GB/T 13025.7-1999). Results Qualified rate of wholesale iodized salt was 100%(378/378) during 2008 - 2010, and mean salt iodine was 30.4 mg/kg;qualified rate of household iodized salt was 99.8%(2417/2421 ), and mean salt iodine was 30.4 mg/kg; iodized salt coverage rate was 99.6% (2421/2430) and consumption rate of qualified iodized salt was 99.4% (2417/2430).Conclusions Qualified rate of iodized salt, coverage rate of qualified iodized salt and consumption rate of qualified iodized salt are 90% or more, which has reached the standard of sustainable elimination of iodine deficiency disorders.

Objective To explore the relationship between serum advanced glycation end products(AGEs) levels in gestation diabetic mother(GDM) and cardiovascular function of newborn infants.Methods Sixty mid-gestation GDM and 72 late-gestation GDM fulfilling the inclusion criteria were recruited,72 mid-gestation and 80 late-gestation mothers with no pregnancy complications were collected as controls.Fasting blood glucose and serum AGEs levels were analyzed in each group.Clinical data of GDM and their babys were collected.Accor-ding to cardiovascular function of neonates,these neonates were divided into 2 groups:normal neonate group with normal cardiovascular function and anormal neonate group with anormal cardiovascular function.Maternal serum AGEs levels,blood glucose between mid-gestation groups and late-gestation groups were compared.Factors which affected the prevalence of complications of fetal outcome in GDM were analyzed.Results 1.Mid-gestation and late-gestation GDM groups had higher serum AGEs levels and fasting blood glucose compared with those of their respective controls(Pa0.05).3.Abnormal fetal outcome in GDM had significantly higher maternal serum AGEs levels than that in controls with normal fetal outcome(P

Objective The Toxicology study of Tibetan medicine MNXT granules was observed to provide basis for clinical safe medication.Methods The acute toxicity test in mice was conducted with the oral maximum-tolerated dosage,and then toxicity reaction and death situations in mice at 14d after the intragastric administration (ig) one day at 3 times was observed; Long-term toxic test:the does of MNXT granule 13.23 g/kg · d-1,6.667 g/kg· d-1,3.33 g/kg· d-1 (equivalent 100,50,25 times of the clinical dosage) were continuous administered to medicating groups for 30 days,and blank group was given distilled water instead.The rats'behavior,appearance,food intake,water intake,body weight were observed,and the blood,blood biochemical parameters,the main organ coefficient,anatomical,pathological morphology were determined at 30d after administration and 15d after withdrawal.Results The maximum study medication dose of Tibet an medicine MNXT granule was 39 g/kg (equivalent to 300 times the clinical dose) and the mice had not any adverse reaction.Long-term toxicity test:the rats' blood and blood biochemical parameters,the main organ coefficient,anatomical,pathological morphology had not significant differences compared with the blank grou? during the 30d administration and 15d withdrawal.Conclusion Toxicity of the Tibetan medicine MNXT granules was not observed in acute or long-term toxicity test.

Objective To determine the optimum dose of pentazocine when combined with propofol for gastroscopy in elderly patients.Methods One hundred and forty ASA physical status Ⅰ or Ⅱ patients,aged 6575 yr,scheduled for elective gastroscopy under general anesthesia,were randomly assigned into Ⅰ-Ⅳ groups (n =35 each) using a random number table.Before insertion of the gastroscope,pentazocine 0.2,0.4 and 0.8 mg/kg were injected intravenously in Ⅱ-Ⅳ groups,respectively,while the equal volume of normal saline was given in Ⅰ group.Propofol was then administered by target-controlled infusion (TCI).The half-effective concentration (EC50 of propofol was determined by up-and-down sequential trial.The target plasma concentration (Cp) was set at 3.5 μg/ml in the first patient.Gastroscopy was performed at 5 min after the target effect-site and plasma concentrations were balanced.The response to gastroscopy was defined as positive when body movement and/or bucking occurred during gastroscopy.Each time the Cp increased/decreased by 0.3 μg/ml in the next patient depending on whether or not the response to gastroscopy was positive.EC50 and 95 ％ confidence interval of propofol TCI inhibiting the response to gastroscopy were calculated using Probit analysis.The development of respiratory depression and hypotension was observed.Results EC50 (95 ％ confidence interval) of propofol TCI inhibiting the response to gastroscopy was 2.82 (2.63-3.02) μg/ml,2.78 (2.58-2.97) μg/ml,2.16 (2.00-2.32) μg/ml and 2.03 (1.88-2.19) μg/ml in Ⅰ-Ⅳ groups,respectively.Compared with group Ⅰ,EC50 was significantly decreased in Ⅲ and Ⅳ groups,and the incidence of respiratory depression was increased in Ⅳ group (P ＜ 0.05).Conclusion The optimum dose of pentazocine when combined with propofol is 0.4 mg/kg for gastroscopy in elderly patients.

Objective:To investigate the effects of nitric oxide(NO) and inducible nitric oxide synthase (iNOS) in the experimental abdominal aortic aneurysm (AAA) rat model.Methods:An intra-aortic elastase infusion model was used.Control rats received intra-aortic saline infusion.In the remaining groups,intra-aortic elastase infusion was used to induce aneurysm formation.These rats were treated with intraperitoneal injections of saline postoperatively(experimental group),aminoguanidine postoperatively(medicine group).Serum NO and aortic diameter were measured,Changes of histology,iNOS and MMP-9 were observed in the aortic wall.Results:Experimental group produced AAAs with significant production of iNOS,MMPs and serum NO compared with controls.In medicine group reduced aneurysm size and displayed suppression of MMPs expression,inflammatory infiltrates and serum NO production were detected.Conclusion:Expression of iNOS and MMP-9 are induced and serum NO levels are increased in experimental AAA,iNOS and NO production by iNOS play an important role with detrimental effects during experimental aneurysm development.
