The correlative analysis of the results was performed. Results (1) Serum leptin level in PIH women was (40.02?8.92)?g/L, notably higher than that (24.67?5.23) in normal pregnant women( P

Aim To investigate if anti-depressive effect of venlafaxine was associated with improving oxi-dative stress and expression of hippocampus NET and 5-HTT in rat model induced by CUS. MethodsEighty SD male rats were randomly divided into four groups:model group(MG),normal group(NG), ven-lafaxine-treated normal group ( VNG ) , and venlafax-ine-treated model group ( VMG) . VNG and VMG were given venlafaxine (23. 4 mg·kg-1 ·d-1 ) once daily;NG and MG were given the same volume solvent. Soli-tary condition with chronic unpredicted stress ( CUS ) was taken to establish rat depression model. The force swimming test was used to evaluate the behavior chan-ges of experimental rats. The malondialdehyde ( MDA) level and activity of superoxide dismutase ( SOD ) in serum were determined by biochemical methods. The mRNA and protein expressions of NET and 5-HTT in
hippocampus were determined by Real-Time Reverse transcription polymerase chain reaction ( real-time RT-PCR) and Western blot ( WB) , respectively. Results Compared with NG rats, obviously increasing immo-bile time of rats in force swimming test and serum MDA level, as well as significantly decreasing SOD activity in serum was observed with clearly decreasing 5-HTT expression and elevating NET expression in hippocam-pus of MG rats. The treatment of venlafaxine distinctly suppressed changes above from CUS-induced rats. However, significant changes failed to be found in VNG rats. Conclusion The anti-depressive effect of venlafaxine may at least partly involve in improving ox-idative stress/anti-oxidative stress balance and revers-ing abnormal expression of NET and 5-HTT.

Aim To investigate whether chronically un-predictable stress (CUS)-induced depression-like be-haviors of rats is associated with the variant expression of tryptophan hydroxylase (TPH)and tyrosine hydrox-ylase (TH).Methods 30 male SD rats were ran-domly divided into depression model group(MG)and control group (CG),the former was established using CUS plus solitary condition for 28 d,whereas the latter was fed normally as five rats per cage without CUS. The open field test(OFT)and the sucrose preference test were used to evaluate depressive behaviors.Both mRNA and protein expressions of TPH and TH in hip-pocampus and forebrain cortex were determined by re-al-time fluorescent quantitative PCR and western blot (WB),respectively.Results MG rats showed obvi-ous depressive behaviors with much lower locomotive activity and sucrose preference than CG.Meanwhile, the mRNA and protein expressions of TPH and TH also significantly decreased in MG rats,compared with CG rats.Conclusion The depression behaviors of rats in-duced by CUS may be associated with down-regulation of TPH and TH expression.

Objective To investigate the clinical features and effective treatment of patients with severe type A H1N1 flu in Wenzhou. Methods The clinical data of 42 hospitalized patients with severe type A H1N1 flu were analyzed and the clinical features were summarized. Results A total of 42 patients with severe type A H1N1 flu all began with fever and cough. The symptoms of expectoration, pharyngalgia, chilly accounted for 92. 9%, 90. 5% and 42. 9%, respectively. The peripheral leucocyte counts were normal or reduced. C-reactive protein and erythrocyte sedimentation rate levels both increased in 30 patients (71.4%). About 95.2% (40/42) patients had changes of pulmonary imaging. All of the patients were treated with oseltamivir and effective antibiotic drugs as well as symptomatic management. No patients was treated with glucocorticoid. The patients with underlying diseases were given proper treatment. Three cases were treated with antifungal therapy and 3 pregnant patients were timely terminated of pregnancy. Conclusions Severe type A H1N1 flu progresses rapidly and the lower respiratory tract is involved soon after onset. Therefore, the patient should be diagnosed early and treated promptly after presenting fever, which will lead to good prognosis.

Objective To investigate the isolation rate, distribution and trend of nontuberculous mycobacteria (NTM) in Wenzhou during 2014 to 2016.Methods Sputum or alveolar lavage specimens of patients with suspected pulmonary tuberculosis were collected for mycobacteria culture from January 2014 to December 2016.Mycobacterium culture positive strains were further identified by gene chip, 16S rRNA and hsp65 gene sequencing.SPSS 19.0 software was used to analyze the data.Results After excluding repetitive strains, 3 295 mycobacteria strains (MTB) were isolated from respiratory specimens, included 3 032 mycobacterium tuberculosis complex strains, 238 NTM strains, 20 Gordon genera strains, 3 Nocardia genera strains and 2 Tsukamurella genera strains.The proportion of NTM among confirmed mycobacteria was 8.5％ (86/1 006), 6.7％ (72/1 079) and 6.8％ (80/1 185) in 2014, 2015 and 2016, respectively (x2 =2.459,P ＞ 0.05).The overall prevalence of NTM was 7.3 ％ (238/3 270).There were 15 species of NTM, and the most common NTM strain was Mycobacterium intracellulare (52.5％,125/238), followed by Mycobacterium abscessus (22.7％, 54/238) and Mycobacterium avium (10.1％, 24/238), other species were only accounted for 14.7％ (35/238).The ranking of Mycobacterium avium went up rapidly from the fifth in 2014 to the second in 2016 (x2 =18.259, P ＜ 0.01), while proportion of Mycobacterium abscess, dropped from 34.9％ (30/86) in 2014 to 17.5％ (14/80) in 2016 (x2 =7.335, P＜0.01).Among patients from whom the NTM strains were isolated, 56.7％ (135/238) were male and most of them were aged 45 years or above (79.8％, 190/238).Conclusions In the past three years, the trend of NTM isolation rate in Wenzhou is steady.The most prevalent NTM species is Mycobacterium intracellulare, followed by Mycobacterium abscessus and Mycobacterium avium.Mycobacterium avium shows a continuously upward trend, while the separation of Mycobacterium abscessus shows a downward trend.

OBJECTIVETo investigate the molecular?mechanisms by which triptolide induces apoptosis of human acute T lymphocytic leukemia Jurkat cells.

METHODSMTT assay was employed to detect the proliferation inhibition of Jurkat cells by triptolide, and the IC50 was calculated by OriginPro8. Flow cytometry was used to analyze apoptosis of Jurkat cells. Np9 mRNA levels were detected by RT-PCR and analyzed quantitatively by Kodak 1D 3.6 software. Correlation between the inhibition of Np9 transcription and the cell apoptosis was analyzed by SPSS 19.0.Western blotting was employed to determine Np9 downstream signaling molecules c-myc, β-catenin, ERK, AKT and Notch1 protein level in Jurkat cells after exposure to different concentrations of triptolide for 48 h.

RESULTSTriptolide treatment resulted in dose-dependent inhibition of Jurkat cells proliferation and its IC50 was 12.7 nmol/L. Triptolide induced apoptosis of Jurkat cells in dose- dependent manner. Furthermore, triptolide inhibited Np9 mRNA transcription level in Jurakt cells in a dose-dependent manner. There was a correlation between the triptolide-mediated the apoptosis and the inhibition of Np9 transcription of Jurkat cells (R(2)=0.907). Western blotting results displayed that triptolide inhibited transcription levels of Np9 mRNA with a concomitant decrease of its downstream signaling molecules c-myc, β-catenin, ERK, AKT and Notch1 at protein levels.

CONCLUSIONInhibition of HERV-K Np9 mRNA and its downstream signaling molecules c-myc, β-catenin, ERK, Akt and Notch1 protein might be one of important molecular?mechanisms by which triptolide induces apoptosis of human acute T lymphocytic leukemia Jurkat cells.
