Objective To explore target organ damage in the youth with pre-hypertension. Methods 77 consecutive youth visiting our institution form 2008 to 2010 were divided into pre-hypertension group (n=32) and control group (n=45). The relevance of left ventricular mass index (LVMI), left ventricular end-diastolic diameter (LVDd), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), carotid plaque intima-media thickness (IMT) and glomerular filtration rate (GFR) were compared. Results The blood pressure of pre-hypertension group was higher than that of control group, and the pre-hypertension group followed higher family hypertension history (P<0.05). There was no difference in LVDd, IVST, LVPWT, carotid plaque IMT and GFR between 2 groups (P>0.05). Compared with the control group, LVMI increased (P<0.05) and the E/A ratio decreased (P<0.05). Conclusion Target organ damage in pre-hypertension youth is salient compared with changes in renal function and damage of arteriosclerosis, and heart damage is more often occurred in the obese youth with pre-hypertension.

AIM: To study effects of hyperbaric oxygen (HBO) and cyclosporin A (CsA) on the contents of active oxygens and nitric oxide (NO) in spleens of skin transplanted mice. METHODS: The donor mice BALB/C and receptor mice Cs7BL/6 were tested for skin transplantation. The HBO group mice were,treated with 99.2 % oxygen under 0.25 MPa for 1.5 hours, while CsA group mice were treated with CsA 0.5 rmg· kg- t· d- 1 by abdomen injection. After 14 days, the spleen were extracted the contents of malondialdehyde (MDA) and NO and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH - PX), catalase (CAT) and NO synthases (NOS) were determined. RESULTS: (1) Compared with the control group, the transplantation group, HBO group and CsA group have markedly increased the content of MDA and the activities of GSH - PX and CAT; Compared with the transplantation group, the CsA group have markedly increased activity of SOD and reduced activities of GSH - PX and CAT; the HBO group have markedly reduced the activity of GSH - PX and increased the activities of CAT and SOD (P < 0.01 ). (2) Compared with the control group, the transplantation group have markedly increased the content of NO and the activity of NOS; Compared with the transplantation group, the HBO group have markedly increased the activity of NOS and reduced the content of NO ( P < 0.01 ); The content of NO and the activity of NOS in CsA group was not changed significantly. CONCLUSION: In the lymphocytes of the transplantation group, the peroxidation is intensified, and the content of NO and the activity of NOS increased. HBO and CsA may activate the systems of oxidation/antioxidation and NO/NOS in spleen, which may be related to their mechanism of inhibition rejection.

Objective:To observe the effect of warm-unblocking acupuncture plus fluticasone propionate nasal spray on the pulmonary ventilation, level of interferon-γ (IFN-γ) and sleep quality in patients with allergic rhinitis (AR). Methods: A total of 112 AR patients were enrolled between January 2013 and August 2018 and were divided into an observation group and a control group by the random number table method, with 56 cases in each group. Patients in the observation group received warm-unblocking acupuncture plus fluticasone propionate nasal spray, and patients in the control group only received fluticasone propionate nasal spray. The nasal symptom score, pulmonary function indexes, the levels of IFN-γ and interleukin (IL)-4 in serum, and sleep quality in the two groups were compared. Results: After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The nasal symptom score dropped in both groups after treatment (both P<0.05), and the score in the observation group was lower than that in the control group (P<0.05). The pulmonary ventilation indexes all increased significantly after treatment in the observation group (all P<0.05); the forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio (FEV1/FVC) and the forced expiratory flow at 50%, 75% and 25%-75% of the vital capacity (FEF50%, FEF75%, FEF25%-75%) increased after treatment in the control group (all P<0.05); the pulmonary ventilation indexes were higher in the observation group than those in the control group (all P<0.05). The level of IFN-γ increased significantly after treatment in the two groups (both P<0.05) and the level of IL-4 dropped significantly (both P<0.05); the observation group had a higher IFN-γ level (P<0.05) and a lower IL-4 level (P<0.05) compared with the control group. Regarding the Pittsburgh sleep quality index (PSQI), the scores of subjective sleep quality, habitual sleep efficiency and sleep disturbances and the general PSQI score decreased significantly after treatment in both groups (all P<0.05), and the scores in the observation group were significantly lower than those in the control group (all P<0.05). Conclusion: Warm-unblocking acupuncture plus fluticasone propionate nasal spray can effectively control the clinical symptoms and improve pulmonary function in the treatment of AR; this approach can regulate the levels of IFN-γ and IL-4 towards the normal range in AR patients; it can also improve patient’s sleep quality. This method can produce more significant efficacy than fluticasone propionate nasal spray used alone.

Objective To investigate the expression of caspase-10 in differentiated thyroid carcinoma and association with its development and metastasis. Methods Thyroid samples from 37 patients in a period from January 2006 to December 2007, with differentiated thyroid carcinoma were retrospectively analyzed for caspase-10 by immunohistocbemistry(streptavidin-perosidase, S-P), compared to control group of 46 cases with nodtdar goiter. The relationship between the expression of caspase-10 and the clinical pathologic characteristics of thyroid carcinoma were also explored simultaneously. Results caspase-10 were observed as brown or yellow particles located in the cytoplasm or cell membrane of nodular goiter but there were no significant evidence for its positive expression in thyroid carcinoma, caspase-10 expression was markedly down-regulated in differentiated thyroid carcinoma(29.73%,11/37) compared with benign nodules(71.74%,33/46, χ2=14.528, P<0.01). The positive expression in 18 cases with lymph node metastasis(11.11%,2/18) was significantly lower than those in 19 patients without lymph node metastasis(47.37%,9/19; χ2=4.210, P<0.01). There was no significant correlation(P> 0.05) between the expression of caspase-10 and the clinical pathologic characteristics including male, age, TNM stage and pathologic type. Conclusion Down-regulation of caspase-10 may play a critical role in carcinogenesis and development of differentiated thyroid carcinoma.

Objective To identify the pathogen of an acute epidemic gastroenteritis outbreak in newborn room. Methods Forty five samples were collected from 38 newborn patients at the peak of a diarrhea outbreak, which happened in a newborn room in Inner Mongolia Autonomous Region during December 2008 to February 2009. The presence of rotavirus antigen, Adeno-like virus antigen and Astrovirus antigen were detected by enzyme-linked immunosorbent assay (ELISA). The presence of Astrovirus RNA were detected by reverse transcriptase polymerase chain reaction (RT-PCR) with universal primer of Astrovirus. Thirteen samples positive for Astrovirus nucleic acid were analyzed by sequencing and phylogenetic tree. Four samples positive for both Astrovirus antigen and Astrovirus nucleic acid were observed by immune electron microscopy. Results Both rotavirus antigen and Adeno-like virus antigen were negative in 45 faecal samples. Thirty samples were positive for Astrovirus antigen when checked by ELISA, which resulted in a positive rate of 66.7%. Thirty-one samples were positive for Astrovirus RNA when check by RT-PCR, which resulted in a positive rate of 68.9%. The genotype results confirmed all patients were infected with genotype 1 Astrovirus. The gene sequences of thirteen samples were compared with reference strains of Astrovirus type 1 in GeneBank and the homology rate of nucleotide sequence was 90.9 %- 96.3 %. The homology rate of intra these thirteen sample was 94.7%-100.0%. Four positive samples were randomly selected and observed by immune electron microscopy and a large amount of Astrovirus particles were found in two of these samples. Conclusion Genotype 1 Astrovirus is the pathogen of this diarrhea outbreak in newborn.
