Objective To evaluate the clinical efficacy of percutaneous transluminal angioplasty (PTA) combined with stent implantation in the treatment of transplant renal artery stenosis (TRAS) after renal transplantation. Methods Clinical data of 21 patients with TRAS after renal transplantation undergoing PTA combined with stent implantation were retrospectively analyzed. The incidence of TRAS in renal transplant recipients was summarized. The changes of relevant indexes in patients with TRAS were statistically compared before and after interventional treatment. Clinical prognosis of patients with TRAS was evaluated. Results The incidence of TRAS in renal transplant recipients was 4.1%(21/507). TRAS was diagnosed at postoperative 5 (4, 7) months, and 67% (14/21) of patients developed TRAS within postoperative 6 months. Compared with the values before interventional therapy, the serum creatinine level, systolic and diastolic blood pressure and peak flow velocity of transplant renal artery of patients with TRAS were significantly decreased, and the estimated glomerular filtration rate (eGFR) and interlobar arterial resistance index were significantly increased at 1 week and 1 month after interventional therapy (all P < 0.05). During postoperative follow-up after PTA combined with stent implantation, 1 patient suffered re-stenosis of the transplant renal artery, which was improved after simple balloon dilatation. One patient developed pseudoaneurysm formation at the puncture site of the right femoral artery. One patient presented with renal atrophy and loss of function due to atresia of the transplant renal artery. All the remaining 18 patients were well recovered after surgery. Conclusions PTA combined with stent implantation is the optimal treatment of TRAS after renal transplantation, which can significantly improve the function of transplant kidney and considerably prolong the survival time of transplant kidney.

Objective To investigate the effects of levothyroxine (Levo-thyroid hormone,L-TH4) in pregnancy subclinical hypothyroidism (SCHT), and study the relationship between L-TH4 with thyroid peroxidase (TPO) and glucose metabolism. The research could provide theoretical basis for the treatment of SCHT. Methods Sixty pregnant women were selected and signed the medical informed consent. The pregnancy were divided into three groups, 20 cases in each group.Normal control group: pregnancy underwent routine thyroid function normal; SCHT group: SCHT pregnancy patients who did not use drugs to treat SCHT; L-TH4 group: SCHT pregnancy patients given L-TH4 treatment. The blood was taken to test the contents of glucose level and HbA1c were observed; the activity of TSH and TPO were tested by ELISA method; HE staining method was used to observe the changing of placenta tissue. Results Compared with normal control group, the glucose and HbA1c were significantly increased in SCHT group (P<0.05). However, L-TH4 could decrease these index, compare with the SCHT group, and reduce the level of TSH and the activity of TPO, the difference was statistically significantly (P<0.05). Moreover, L-TH4 could improve the changing of placenta tissue. Conclusion L-TH4 could reduce blood glucose and HbA1c levels, also reduced the level of TSH and the activity of TPO in SCHT. L-TH4 could improve the changing of placenta tissue.

Aim To investigate the effects of endocrinal petptide urocortin on subthalamic nucleus (STN) neuron''s discharge, also observe the convergence effect of UCN with dopamine (DA) and glutamate (GLU), so as to understand the regulation effects of UCN and its mechanism in Parkinson''s disease (PD).Methods Forty Sprague-Dawley rats were used in this experiment.Nerve electrophysiology method-microiontophoresis was used to observe the effects of UCN on STN neuron firing rates and firing wave.Astressin (AST, the blocker of CRF receptor 2), protein kinase A (PKA) were used to observe the effects of UCN whether via CRF-2R and PKA signal pathway.Moreover, given UCN during the period of DA and GLU, the effects of UCN on DA and GLU in STN neurons were determined.Results During the period of using the UCN, UCN could inhibit the firing rate of 82% (27/33) STN neuron (P<0.01), and the firing discharge rates were reduced from(3.65±0.27)Hz to (2.05±0.33) Hz (P<0.01).However, the inhibitory effects of UCN in STN could be antagonized by AST.Given UCN during the period of microiontophoresis of inhibitory neurotransmitter (DA) and excited neurotransmitter (GLU), UCN could enhance the effects of DA and attenuate the excitatory effects of GLU (P<0.01).Conclusion UCN and GLU/DA in STN, UCN play inhibitory and regulated effects on STN neurotransmitters(DA and GLU)via CRF-2 receptor and PKA signal pathway.

Objective To establish the method of identifying MRSA with Taqman-fluorescence quantitative PCR basing on mecA/nuc/fem B three gene combined detecting.Methods Taking the coagulase positive MRSA,which isolated from the clinical samples and confirmed by VITEK 2 compact microbial analyzer,as the research obj ect,designed mecA/nuc/fem B specific PCR primers and Taqman fluorescent probe by bio-software PrimerPremier 5 and Designer Beacon 7,FAM,HEX and ROX markers were used to label the fluorescent probe at 5’,and the end of 3’was labeled with BHQ1,detected by fluo-rescence quantitative PCR instrment.Results ①1 g/dl gel electrophoresis results showed that the primer’s specificity of mec A/nuc/fem B were good,and molecular weight of the amplification band consistent with the expected molecular weight and no non-specific amplification band.②Three genes were obtained specific amplification in a single tube single channel and single tube multiple channel detection in PCR,and the three gene amplification effect in a single tube single tube single chan-nel and multichannel PCR similar.Conclusion Successfully established a method of multi channel Taqman-probe fluores-cence quantitative PCR identification of MRSA,mec A/nuc/fem B combined detection can effectively differentiate coagulase negative and positive MRSA,improve the accuracy of identification.

<p><b>OBJECTIVE</b>To examine the influence of China's economic reforms on population health and regional mortality rates.</p><p><b>METHODS</b>Longitudinal study measuring the mortality trends and their regional variations. Using data from the three most recent national censuses, we used the model life table to adjust the mortality levels within the population for each census, and to calculate life expectancy. We then examined the variation in patterns of mortality and population health by economic status, region and gender from 1980-2000.</p><p><b>RESULTS</b>Life expectancy varied with economic status, province, and gender. Results showed that, although life expectancy in China had increased overall since the early 1980s, regional differences became more pronounced. Life expectancy for populations who live in the eastern coastal provinces are greater than those in the western regions.</p><p><b>CONCLUSION</b>Differences in life expectancy are primarily related to differences in regional economic development, which in turn exacerbate regional health inequalities. Therefore, it is necessary to improve economic development in less developed regions and to improve health policies and the public health system that address the needs of everyone.</p>
