This paper is devoted to discussing two research patterns of biological basis of traditional Chinese medicine syndrome and presenting a research strategy for data mining methods. It points out that data mining methods which are based on feature selection are better fit for investigating biological basis of traditional Chinese medicine syndrome. Based on such a discussion, the concept of "characteristic pattern" is proposed to bridge the gap between "golden index" and biological basis of traditional Chinese medicine syndrome. This paper presents a novel research avenue for investigating biological basis of traditional Chinese medicine syndrome.

The aim of the study is to investigate the effect of nardosinone (Nar) on neuronal injury induced by oxygen-glucose deprivation (OGD) in primary cortical cultures isolated from embryos at gestational day 14. MTT method was used to determine the dosage regimen of Nar in primary neuronal cultures and observe the influence of Nar on the neurons suffering OGD; Western blotting analysis was used to detect expressions of protein kinase A (PKA), Ras related protein 1 (Rap1), mitogen-activated protein kinase kinase 1 (MEK1) and phospho-extracellular signal-regulated kinase 1/2 (p-ERK1/2) of OGD-injured or uninjured primary cultured neurons after Nar treatment. Results showed that Nar (50 and 100 micromol x L(-1)) improved the cell viability during OGD damage (P < 0.01) and increased the expression of PKA, Rap1, MEK1 and p-ERK1/2 in injured neurons. Additionally, elevations of PKA, Rapl, MEK1 and p-ERK1/2 in uninjured neurons were caused by Nar (50, 100 and 200 micromol x L(-1)) with a dose-dependent tenclency as well (P < 0.01). In conclusion, Nar could protect against the neuronal injury exposed to OGD, which may be relevant to the promotion of PKA and ERK signaling pathway.

Objective To understand the status of Ascaris eggs pollution in soil at national monitoring spots of soil-transmit-ted nematodiasis,so as to provide the evidence for making countermeasures and evaluating the control effect. Methods Ten households were selected from each of the 22 national monitoring spots annually according to the National Surveillance Program of Soil-Transmitted Nematodiasis(Trial),and the soil samples from vegetable gardens,toilet periphery,courtyards and kitchens were collected and examined by using the modified floatation test with saturated sodium nitrate. Fertilized or unfertilized eggs as well as live or dead fertilized eggs were discriminated and identified. In addition,a SWOT analysis of monitoring of Ascaris eggs pollution in the soil of rural China was carried out. Results A total of 1 090 households were monitored in 22 monitoring spots from 2006 to 2010. The total detection rate of Ascaris eggs in the soil was 30.73%,and the detection rates of fertilized,unfertilized and live fertilized eggs were 13.21%,26.42%and 20.28%,respectively. The total detection rates of Ascaris eggs in the vegetable garden,toilet periphery,courtyard and kitchen were 16.51%,13.49%,14.22% and 10.73% respectively. The SWOT analysis demonstrated that the monitoring work had both advantages and disadvantages,and was faced with opportunities as well as threats. Conclusion The pollution status of Ascaris eggs in the soil is still quite severe at some national monitoring spots,and the counter-measures such as implementing hazard-free treatment of stool,improving water supply and sanitation and reforming environment should be taken to protect people from being infected.

Objective To understand the infection status and variation tendercy of Enterobius vermicularis infection among children at national monitoring spots of soil-transmitted nematodosis from 2006 to 2010,and master the epidemic regularity,so as to provide the evidence for making control strategy and evaluating the control effect. Methods A total of 22 national monitor-ing spots of soil-transmitted nematodosis were established according to the National Surveillance Program of Soil-Transmitted Ne-matodiasis(Trial),and the children aged 3-12 years were examined through adhesive cellophane anal swabs,then the infec-tion rates of children with different ages,genders,nationalities and education levels were analyzed. In addition,the advantage, disadvantage,opportunity and threat of the monitoring work were analyzed by SWOT analysis. Results A total of 17 068 chil-dren were examined in 22 monitoring spots from 2006 to 2010,and 1 363 of them were found being infected with E. vermicu-laris,the average infection rate was 7.99%,and the infection rates of male and female children were 7.39%and 8.70%,respec-tivel;the average infection rates in each year were 10.01%,9.68%,7.41%,6.96%and 6.57%,respectively. From 2006 to 2009,the infection rates of E. vermicularis in children in Fujian Province was the highest,which were 56.15%,53.42%, 37.82%and 49.53%,respectively,but in 2010,the infection rate in Guangdong Province(46.06%)was the highest. The fur-ther analysis demonstrated that the female children,3-6 age group,Li nationality and children at kindergarten stage had relative-ly high infection rates. The SWOT analysis showed that the advantage of E. vermicularis monitoring in China was its wide cover-age and continuity,and the disadvantage was the relatively small investment from the government,the opportunity was that the national monitoring spot could drive the monitoring work at the provincial,county and other levels,and the threat was that the work was paid less and less attention to in recent years. Conclusion Though the infection rate of E. vermicularis in children at national monitoring spots of soil-transmitted nematodosis has been decreased year by year,high-endemic areas still exist,and thus the work on enterobiasis control and prevention still needs to be strengthened.

Chinese Journal of Medical Imaging Technology 2019;35(8):1234-1238
Objective:To explore MRI findings and clinical characteristics of adnexal torsion (AT) in pregnancy. Methods: Clinical and MRI data of 14 patients in pregnancy with pathologically confirmed AT were retrospectively analyzed. Results: There were 2 cases of primary AT and 12 cases of secondary AT (5 with ovarian cyst, 4 with ovarian teratoma, 2 with hydrosalpinx and 1 with tubal mesothelial cyst). AT occurred on the right side in 5 cases and on the left in 9 cases, with torsion angles ranged from 180° to 1 720°. MRI showed that except for 3 cases of solitary AT, ovarian enlargement occurred in 11 cases. Mass in pelvic or abdominal cavity was found in 12 cases, including 8 cystic masses and 4 cystic solid masses. The torsional pedicle next to the masses presented typical "beak sign" in 6 cases, while 1 case showed whirlpool sign, all showed mixed high signal in DWI. Adnexal hemorrhage was noticed in 6 cases and pelvic effusion in 8 cases. The pregnancy outcome was 6 full-term healthy fetuses and 8 preterm infants. Conclusion: MRI findings of AT in pregnancy have certain characteristics, which are helpful to diagnosis of AT combined with clinical manifestations.

Chinese Journal of Interventional Imaging and Therapy 2019;16(7):425-429
Objective To: observe CT and MRI features of endometrial stromal sarcoma (ESS). Methods: Plain and enhanced imaging data, including CT (n=5) and MRI (n=6) of 11 patients with ESS confirmed by postoperative pathology were analyzed retrospectively. Results: There were 9 cases of singe low-grade ESS and 2 cases of single undifferentiated sarcoma. The lesions located in the uterine cavity in 7 cases, in the myometrium in 4 cases, manifested as circular masses in 8 cases and as irregular masses in 3 cases. The mean maximum diameter of lesions was (9.18±1.36)cm. The boundaries of lesions were clear in 4 cases and unclear in 7 cases. Based on CT and MRI findings, there were 4 patients with solid masses, 6 patients with solid-cystic masses and 1 case with cystic mass. Solid component of lesions manifested as iso- or hypo-attenuation compared with myometrium on plain CT images in 5 patients, including 4 cases with nonuniform density lesions and 1 case with uniform density lesion. MRI showed signal reducing on ADC images in 6 patients. Among them, lesions in 5 cases manifested as iso- or hypo-signal on T1WI, hyper-signal or slightly high signal on T2WI, and slightly high signal on DWI, lesion in another case (cystic mass) manifested as hyper-signal on T1WI, high signal on T2WI and high signal in central area of lesion on DWI. Incremental and continuous enhancement were found in 10 cases, while no enhancement was found in the rest one case (cystic mass). Cystic and necrosis changes were found in 8 cases, and invasions of deep layer myometrium were found in 6 cases. Some of the patients had complications, including adenomyosis in 2 cases, uterine fibroid in 5 cases, pelvic effusion in 5 cases, intrauterine hemorrhage in 1 case and salpingian dropsy in 2 cases. Conclusion: ESS has characteristic CT and MRI findings, which can provide useful references for diagnosis.
