OBJECTIVE: To observe the effects of Ginkgolides inhalation on eosinophils infiltration in airway of asthmatic guinea pig model. METHODS: Guinea pigs were divided into seven groups(n=8 in each group): model group, ginkgolides inhalation low, medium and high dosage groups(5, 10, 20mg?kg-1, respectively), ginkgolides ip group (at a dosage of 20 mg?kg-1), Dexamethasone ip group (at a dosage of 10 mg?kg-1), normal control group. The eosinophils (EOS) in bronchoalveolar lavage fluid (BALF) and trachea were counted. RESULTS: As compared with normal control group, the number of EOS in BALF was significantly increased in model group, but that in BALF and trachea of the Ginkgolides inhalation group was significantly reduced(P

Objective To understand the schistosomiasis epidemic situation among migrant population,so as to assess the potential risk of schistosomiasis transmission in Haining City. Methods Five districts in Haining City were randomly selected to investigate the schistosomiasis endemic situation in migrant population from the schistosomiasis endemic provinces. Results Totally 1207 persons were investigated and four positives were found in serological tests,with the positive rate of 0.33%,but no patients were found in pathologic tests. The positive cases in serological tests were mainly between 31-40 years old,with the pos-itive rate of 1.68%,which was higher than that of other age groups( χ2 = 6.590,P < 0.05). Conclusion The schistosomiasis surveillance work in migrant population still should be strengthened in Haining City.

ObjectiveTo evaluate the efficacy of short-segment transpedicular fixation combined with augmentation vertebroplasty in treatment of thoracolumbar burst fractures. MethodsFrom November 2006 to September 2009, 37 patients with thoracolumbar burst fracture were admitted and received transpedicular fixation combined with calcium sulfate cement augmentation vertebroplasty, and the clinical data including fracture types, complications and following-up results were collected for analysis. The multimethod evaluation strategies involved the anterior vertebral body height, the sagittal Cobb's angle, the restoration of nervous function, internal fixation failure, visual analogue scale (VAS) and Oswestry disability index (ODI) were retrospective analyzed. Results All patients were followed up for average 19 months (range, 14-37). There were no internal fixation failure, loss of reduction, neurological complications in all the patients. In 16 patients with partial neurologic deficits, 14 initially improved at the final follow-up, with no deterioration of neurologic functions. The mean time of calcium sulfate cement obvious absorption and union was 3 months and 5 months postoperatively, respectively. The anterior vertebral body height was 55.40%before surgery and 85.46% after surgery on average, ended up with 82.35%. The sagittai Cobb's angle was improved from 22.45° to 6.86°, ended up with 9.66° on average. The mean VAS and ODI at the final followup were respectively 1.2 and 20.4 on average. ConclusionShort-segment transpedicular fixation combined with augmentation vertebroplasty appears to be effective in achieving stable biomechanics with high security,which seems to be a feasible option in the management of thoracolumbar burst fractures.

OBJECTIVETo study the effect of Guanxin No. 2 (GX2) on gene variant expression profile in rats after myocardial infarction (MI).
METHODSSix SD rats were equally randomized into the sham operated group, the model group and the GX2 group, and they received gastric perfusion with water and GX2 (10 g/kg) respectively. MI model was established by ligating the left-anterior descending branch of coronary artery after 10 days of perfusion, and rats' myocardial tissue in the junction zone was assessed 24 h later for gene chip detection with DNA microarray. Then a cluster analysis was conducted, and the different expressions of key genes were verified by real-time reverse transcription-polymerase chain reaction.
RESULTSThe up-regulating gene expressions in myocardial tissue in the junction zone increased after ischemia. After GX2 intervention, the up- or down-regulating gene expressions, especially the 2 genes, all-trans-13,14-dihydroretinol saturase (AF465614) and similar to expressed sequence AW413625 (AA799328) decreased significantly. In the common genes, more genes involving activity of signal transducer presented in the model group and the GX2 group and those in the latter showed a certain specificity.
CONCLUSIONGX2 could improve the characteristics of variant gene expression profile in MI rats to a certain extent.

Objective:To determine the clinical features of papillary thyroid microcarcinoma (PTMC) and the risk factors for central compartment lymph node (CCLN) metastasis in PTMC. Methods:Data of 1 401 patients with PTMC who were treated in Tianjin Medi-cal University Cancer Institute and Hospital between January 2014 and December 2014 were retrospectively analyzed. Chi-square test and multivariate Logistic regression analysis were used to study the risk factors. Results:With regard to clinicopathological features, the sex ratio is 1:3.4 in patients with PTMC. CCLN metastasis affected 427 (30.5%) of the total 1 401 patients. Age (χ2=14.587, P<0.01), sex (χ2=21.636, P<0.01), tumor multifocality (χ2=35.505, P<0.01), tumor size (χ2=58.868, P<0.01), tumor site (χ2=8.385, P<0.05), and extracapsular/extraglandular invasions (χ2=26.481, P<0.01) were significantly correlated with CCLN metastasis. For patients with a soli-tary primary tumor, tumor location in the lower third of the thyroid lobe was associated with a higher risk of CCLN metastasis (48.1%). The male gender, age<45 years, tumor size>6 mm, extracapsular spread, and tumor bilaterality were independently correlated with CCLN metastasis. Conclusion:A prophylactic neck dissection of the central compartment must be considered particularly in male PT-MC patients with age<45 years, tumor size>6 mm, extracapsular spread, and tumor bilaterality.

OBJECTIVETo explore correlation between lung and large intestine and the two meridians under pathological condition in the view of meridian theory.
METHODSNinety-six cases of bronchial asthma were applied palpation at the running course of 12 regular meridians under the elbow and knees and back-shu points. And abnormal reactions were recorded, the affected meridians and back-shu points were discovered.
RESULTSThe abnormal reactions most frequently appeared on the Lung Meridian, followed by the Large Intestine Meridian, the Spleen Meridian, the Liver Meridian, the Stomach Meridian and the Triple Energizer Meridian. And the unusual reaction of the back-shu points most frequently appeared on Feishu (BL 13), and Dachangshu (BL 25) and Pishu (BL 21) followed as the next two.
CONCLUSIONThe existence of correlation between the Lung Meridian and the Large Intestine Meridians under pathological condition can be proved through meridian and acupoint palpation on bronchial asthma patients.

Aim To observe the effects of panaxdiol saponins component ( PDS-C) extracted and isolated
from Chinese ginseng herb as new Chinese patent med-icine on the promotion of hematopoiesis and the regula-tion of the immune system in treating mice models with aplastic anemia ( AA ) . Methods For preparation of immune mediated AA models, BALB/c mice were ex-posed to sublethal doses of 5. 0 Gy γ radiation, fol-lowed by transplanted lymphocytes from DBA/2 donor mice. The mice models were divided into six groups in-cluding normal control, AA model, PDS-C treated groups with lower, medium and higher dosages, cy-closporine ( CsA) as positive drug control. Both PDS-C and CsA were administered by gastrogavage for 15 days. The peripheral blood cells counts and bone mar-row pathological examination were tested, the percenta-ges of Th1/Th2/Treg cells from spleen were measured, the protein expression levels of T-bet, GATA-3 and FOXP3 transcription factors in spleen cells were detec-ted. Results Curative effect of PDS-C on treating AA
mice was satisfactory. The peripheral hemoglobin, white blood cells and platelet counts in PDS-C groups with medium and higher doses were significantly higher than those in model control. Meanwhile, PDS-C ele-vated the percentages of Th2 cells and Treg cells, but decreased the percentage of Th1 cells, as well as up-regulated the GATA-3 , FOXP3 and down-regulated the T-bet protein levels. Conclusion PDS-C possesses the activities of promoting hematopoiesis obviously. It can improve marrow myelosuppression, enhance the re-covery of hematopoiestic function, and elevate the pe-ripheral blood cells counts. PDS-C also pays its immu-noregulatory efficacy though recovering from unbal-anced Th1/Th2/Treg cells in treating immune media-ted AA mice.
