Objective To increase the awareness of thyroid diseases through observing the relationship between ultrasound indications of thyroid and thyroid disease,and to enhance the understanding of thyroid disease through outpatient data.Methods Two hundred women aged 25 to 50 with thyroid imaging data were selected from the Department of Ultrasonography,the First Affiliated Hospital of Harbin Medical University.Seven indications including age,body weight,thyroid volume,the number of nodules,nodule size,nature of nodules and thyroid disease were recorded.Thyroid cases were divided into four groups based on their sonographic changes of color Doppler ultrasound:normal group (136 cases):sonographic changes of thyroid were approximately normal ; mild degree group (9 cases):consisting of patients with mild thyroid disease,diffused thyroid enlargement or combined cystic nodules; moderate degree group (38 cases):consisting of patients with moderate thyroid disease,hyperthyroidism or hypothyroidism; severe degree group (17 cases):consisting of patients with severe thyroid disease,thyroiditis and/or with hemorrhage and calcification.Data were analyzed using the method of clinical case observation and SPSS 16.0.Results We found that in mild degree group the discriminant coefficients of thyroid volume,the nature of thyroid nodules and nodule size were 0.085,0.169 and 0.695; but in sever degree group the corresponding values were 0.158,0.344 and 0.484,respectively,and the difference between the two groups was statistically significant (x2 =43.3,df =18,P ＜ 0.01).Conclusions The nature,size and area of thyroid nodules are closely related to the progression of thyroid disease.The color Doppler ultrasound data of outpatients as a part of hospital statistics have important theoretical and practical value.

OBJECTIVETo identify the Cynomorii Herba and its analogues species using DNA barcoding technique.

METHODTotal genomic DNA extracted from all materials using the DNA extraction kit. The internal transcribed spacer 2 (ITS2) regions were amplified using polymerase chain reaction (PCR), and purified PCR products were sequenced bi-directionally. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner 3.7.1. The Kimura 2-Parameter (K2P) distances and GC content were computed using MEGA 5. 0. Species identification analyses were conducted through the species identification system for traditional Chinese medicine and neighbor-joining (NJ) trees.

RESULTThe ITS2 sequence lengths of Cynomorii Herba were 229 bp. The average intra-specific genetic distances of Cynomorii Herba were 0.003. The average inter-specific genetic distances between Cynomorii Herba and its adulterants species were 0.760. The results showed that the minimum inter-specific divergence is larger than the maximum intra-specific divergence. The species identification system for traditional Chinese medicine and NJ trees results indicated that Cynomorii Herba and its adulterants species can be easily identification.

CONCLUSIONThe ITS2 region is an efficient barcode for identification of Cynomorii Herba, which provide a new technique to ensure clinical safety in utilization of traditional Chinese medicine.

Objective To investigate the effects of propofol on the phosphoryhtion of α-amino-3-hydroxy5-methyl-4-isoxazolepropionate(AMPA)receptor GluR1 subunits at Serine-831 and Serine-845 sites in the spinal cord dorsal horn in a rat model of visceral pain.Methods Thirty male SD rars,aged 6-8 weeks,weighing 200300 g,in which intrathecal catheters were successfully placed without complications,were randomly divided into 3 groups(n-=10 each):sham operation group(group Ⅰ),visceral pain group(group Ⅱ)and propofol group (group Ⅲ).Visceral pain was induced by injection of 10％ capsaicin 50μl via the rectum in groups Ⅱ and Ⅲ.While the equal volume of normal saline was given instead in group Ⅰ.Group Ⅲ received intrathecal injection of propofol 20 tg at 10 min before injection of capsaicin.While the equal volume of dimethyl sulfoxide was given instead of propofol in groups Ⅰ and Ⅱ.The cumulative pain score was recorded during 30 min after capsaicin injection.The rats were then sacrificed,and the lumbar segment(L3-6)of the spinal cord was removed for determination of the expression of GluR1 subunits and phosphorylation of GluR1 subunits at Serine-831 and Serine-845 sites in the spinal cord dorsal horn.Results Compared with group Ⅰ,the cumulative pain score and phosphorylation of GluR1 subunits at Serine-831 sites and Serine-845 in the spinal cord dorsal horn were significantly increased(P ＜0.05 or 0.01),but there were no significant differences in the expression of GluR1 subunits in groups Ⅱ and Ⅲ (P ＞ 0.05).Compared with group Ⅱ,the cumulative pain score and phosphorylation of GluRl subunits at Serine831 and Serine-845 sites in the spinal cord dorsal horn were significantly decreased in group Ⅲ(P ＜ 0.05 or 0.01).Conclusion Propofol can attenuate the visceral pain through the inhibition of the phosphorylation of AMPA receptor GluR1 subunits at Serine-831 and Serine-845 sites in tte rat spinal cord dorsal horn.
