Objective To observe and analyze the changes of prostaglandin E2 (PGE-2)and elastase (EA)levels in the pulp blood of the patients with carious tooth complicated with exposed pulp and its influence on the curative effects of direct pulp capping treatment.Methods 80 cases of the patients with carious tooth complicated with exposed pulp treated with direct pulp capping treatment were selected as the observation group and 40 cases of the patients treated with normal removal of impacted third molar were selected as the control group.The levels of PGE-2 and EA in the pulp blood of the patients in the two groups before the treatments were detected and compared.A one-year follow-up was employed for the patients in the observation group and the curative effects were evaluated and compared.Results The levels of PGE-2 and EA in the pulp blood of the patients in the observation group were 132.28±63.55 ng/ml and 114.36±19.57μg/ml respectively,and the levels of PGE-2 and EA in the pulp blood of the patients in the control group were 0.61±1.26 ng/ml and 19.38±6.34μg/ml respectively.There were statistically significant differences between the two groups (t=43.129,29.675,P<0.05). There was a positive relationship between the PGE-2 level and EA level in the pulp blood of the patients in the observation group (r=0.782,P<0.05).The levels of PGE-2 and EA in the pulp blood before the treatment of the patients with suc-cessful effects were 84.63±13.17 ng/ml and 68.25±8.16μg/ml,and the levels of PGE-2 and EA in the pulp blood before the treatment of the patients with failed effects were 177.35±41.42 ng/ml and 152.36±16.28μg/ml.There were statisti-cally significant differences between the two types of patients (t=31.578,21.556,P<0.05).Conclusion The patients with carious tooth complicated with exposed pulp show the significantly increased expression levels of PGE-2 and EA in pulp blood.The higher expression levels of PGE-2 and EA before the treatment could put adverse influence on the curative effects of direct pulp capping treatment.The clinicians should give the comprehensive consideration to the specific condition of pa-tients to choose the proper treatment methods.

Objective To observe the effects of nerve impulses on the expression of carbonic anhydrase Ⅲ ( CAⅢ ) and its phosphatase activity, and to explore whether or not the cause of CAⅢ expressive decreased in skeletal muscles of myasthenia gravis( MG) is resulted from the obstruction of nerve impulse.Methods The motor nerves of extensor digitorum longus (EDL, mainly composed by fast fibers) and soleus (Sol, mainly composed by slow fibers) were cut off by operation of denervation.Levels and phosphatase activities of CAⅢ were analyzed at 7, 14, 28, and 56 d after denervation by Western blot and specific enzyme staining on the membrane following SDS-polyacrylamide gel electrophoresis, respectively.Results (1) Levels of CAⅢ in Sol of normal side (eg denervated contralateral) were much higher than that in EDL of normal side, and the levels in both Sol and EDL had an enhanced tendency with time (age) increase, especially for Sol.After denervation, the levels of CAⅢ in EDL were gradual increased, however, the level in Sol was 14 d after denervation as the boundary of ascension and then decline.( 2) The phosphatase activities of CAⅢ in Sol of normal sides were much higher than that in EDL of normal sides, and there were an enhanced tendency with time (age) increase in Sol, but no significant changes were found in EDL The enzyme activities in denervated Sol were lower(in the 14, 28, and 56 days after denervation: 14.39 ±1.93, 11.48 ±1.46, 9.04 ±1.46) much than their contralaterals(22.75 ± 1.80, 25.26 ±3.15, 25.82 ± 2.97; t = 0.002, 0.005, 0.002, all P ＜ 0.05), the enzyme activities in denervated EDL were also lower than their contralaterals, however, no significant differences were found.(3)It was consistent for CAⅢ levels and phosphatase activities in both Sol and EDL of normal sides.After denervation, however, the deviation of the CAⅢ levels and phosphatase activities happened, the levels of CAⅢ were increased, but the phosphatase activities were decreased.Conclusions The effect of nerve impulse transferring obstructed by denervation on CAⅢ expression of skeletal muscles is different from that by MG auto-antibody.The decrease of CAⅢ protein in the MG muscles may be not resulted from the nerve impulse transferring obstructed by MG auto-antibody.

OBJECTIVE: To investigate the statistical method of tri-allelic patterns of STR loci. METHODS: The DNAs of venous blood and blood stain samples from 8,846 unrelated individuals were extracted using magnetic bead method, and STR genotypes were determined by multiplex fluorescent amplification and capillary electrophoresis and analyzed using GeneMapper ID v3.2 software. The genotype frequency and allele frequency of trizonal were determined by direct counting and formula, respectively, in order to deduce the formula of trizonal in paternity test and individual recognition. RESULTS: Of the 8,846 individuals, four tri-alleles and three tri-genotypes were detected. The multiplying of allele frequency and actual rate showed significantly statistical difference. The formula of trizonal in paternity test and individual recognition was successfully deduced. CONCLUSION The frequency of the two alleles inherited as a whole in the population could be calculated by multiplying the frequencies of each allele in the tri-allelic patterns.

OBJECTIVE:To investigate the effects of etomidate combined with propofol on painless gastrointestinal endoscopy and cognitive function of elderly patients. METHODS:Totally 90 elderly patients with painless gastrointestinal endoscopy were ran-domly divided into propofol group(30 cases),etomidate group(30 cases)and combination group(30 cases). Propofol group was given Fentanyl injection 1 μg/kg+Propofol injection 1.5 mg/kg;etomidate group was given Fentanyl injection 1 μg/kg+Etomidate injection 0.3 mg/kg;combination group was given Fentanyl injection 1 μg/kg+Propofol injection 1 mg/kg+Etomidate injection 0.15 mg/kg. The levels of SBP,DBP,HR,MAP and SpO2 at different time points,examination time,anesthesia induction time,recov-ery time and recovery time of orientation were observed in 3 groups. NCSE and MMSE score at different time points,the occur-rence of ADR were also observed in 3 groups. RESULTS:During examination,SBP,DBP,MAP and SpO2 of propofol group were significantly lower than before anesthesia,after examination and those of combination group,with statistical significance(P<0.05);but there was no statistical significance in above indexes of propofol group between during examination and before anesthesia (P>0.05). The recovery time and recovery time of orientation in combination group were significantly shorter than propofol group and etomidate group,with statistical significance(P<0.05),but there was no statistical significance in above indexes between etomidate group and propofol group(P>0.05). The proportion of patients'memory ability,computing ability,orientation ability passing examination in combination group were significantly higher than propofol group,with statistical significance(P<0.05). There was no statistical significance in above indexes between combination group and etomidate group,between etomidate group and propofol group(P>0.05). There was no statistical significance in MMSE score of combination group at different time points (P>0.05);MMSE score of propofol group 15,30 min after anesthesia and that of etomidate group 15 min after anesthesia were significantly lower before anesthesia and combination group,with statistical significance(P<0.05). There was no statistical signifi-cance in MMSE score of propofol group 1 h after anesthesia,etomidate group 30 min and 1 h after anesthesia,compared to before anesthesia(P>0.05). The incidence of apnea,hypotension and injection pain in combination group and etomidate group were low-er than propofol group,the motor response,myoclonus,nausea and vomiting in combination group and propofol group were lower than etomidate group,the tachycardia ease in combination group was lower than propofol group,with statistical significance(P<0.05). CONCLUSIONS:Etomidate combined with propofol anesthesia shows good therapeutic efficacy for painless gastrointestinal endoscopy of elderly patient,can reduce cognitive dysfunction and shortens recovery time,but doesn't increase the occurrence of ADR.
