Objective To investigate the state of thyroid hormones and thyrotropin level in different gestation periods. Methods FT3, FT4, TSH and hCG were measured in 623 patients by ACS-180 automatic chemiluninescence analyzer. The urinary iodine was random measured by the use of iodine catalytic reaction mechanism of Arsenic-Cerium, rapid urinary iodine was detected with cold digestion method of quantitative detection. Result Serum FT3,FT4 ,and hCG levels in the first and second trimester were higher than in the third trimester ( F =53. 19,78.00,58.77, P ＜0. 05) ,and TSH levels were lower than in the third trimester ( F =5.68, P ＜0.05). The incidence of thyrotropin level disorder was 7. 54%, there were no significant differences in the gestation periods ( χ2 = 3.92, P ＞ 0. 05 ). The incidence of subclinical hypothyroidism,subclinical hyperthyroidism, hypothyroidism and hyperthyroidism were 3.53%, 2. 57%, 1.12% and 0. 32%, respectively. The incidence of subclinical hypothyroidism in the first and third trimester was high, while the incidence of subclinical hyperthyroidism in the second trimester was high. Conclusions Thyrotropin level in the third trimester was lower than that of the first and second trimester. HCG changes were not the main reason that caused the thyrotropin level disorder during the pregnancy.

Objectives To explore the clinical effect of coupling meglumine cyclic adenylate (MCA)and the human granulocyte colony-ostimulating factor (G-CSF)on rat with diastolic heart failure(DHF).Methods Totally 60 rats of DHF model were evenly divided into 4 groups according to random number:Control group(n=15,control),Model group(n=15,DHF model),MCA group(n =15,treated with MCA)and MCA+GCSF group(n=15,treated with MCA plus G-CSF).MCA group were administered by intragastric injection of MCA 30 mg/kg/d for 15 d,MCA+G-CSF group were administered by intragastric injection of MCA 30 mg/kg/d and plus G-CSF 100 μg/kg/d for 15 d,while Control group and Model group were given same volume of saline solution.BIOPAC SYSTEM was used to analyze the model establishment.The mRNA levels of GATA-4 and Cx43 were measured by RT-PCR.The protein expressions of GATA-4,Cx43,cTNI and c-kit were measured with western blotting.ELISA and flow cytometry were used to detect cAMP and differentiation rate of bone marrow mesenchymal stem cells (BMSCs),respectively.Results Compared with MCA group,the denaturation degree of myocardial tissues in DHF rat was significantly improved than in MCA+G-CSF group.Moreover,the level of GATA-4 (1.62 ± 0.09),Cx43 (1.02 ± 0.07),cTNI (1.42 ± 0.12),c-kit (0.65±0.02),cAMP(283.67± 18.09)nmol/L and BMSCs cell differentiation rate(38.62 ± 1.52)％ in MCA + GCSF group were significantly promoted (all P＜ 0.05)than in MCA group,GATA-4 (0.82±0.07),Cx43 (0.52±0.05),cTNI(0.86 ± 0.13),c-kit (0.48 ± 0.03),cAMP(198.83 ± 16.03) nmol/L and BMSCs cell differentiation rate (19.82 ± 0.89)％.Conclusions The combination of MCA with G-CSF is significantly improved DHF than single MAC treatment,which may regulate BMSCs differentiation though cAMP/PKA signaling pathways.

BACKGROUND:Ankylosing spondylitis is an autoimmune disease involved in chronic systemic inflammation. Tumor necrosis factor and interleukin-6 levels increased in patients with ankylosing spondylitis. Inflammatory factors such as tumor necrosis factor and interleukin-6 can suppress CD36 expression in monocytes. OBJECTIVE: To analyze the correlation between CD36 expression in monocytes and ankylosing spondylitis. METHODS:A total of 84 newly diagnosed ankylosing spondylitis patients and 111 healthy individuals were included in this study. CD36 expressions in monocytes in ankylosing spondylitis patients and healthy individuals were tested using flow cytometer; meanwhile, biochemistry, immunology, routine blood examination and related inflammatory markers were determined between the two groups. RESULTS AND CONCLUSION:Results of baseline data in both groups demonstrated that CD36 fluorescence intensity in monocytes was significantly lower in patients with ankylosing spondylitis compared with healthy controls (P < 0.01). CD36 fluorescence intensity in monocytes was negatively correlated with C-reactive protein, erythrocyte sedimentation, interleukin-6 and tumor necrosis factor. In addition, CD36 fluorescence intensity in monocytes was negatively correlated with BASDAI score. Logistic regression analysis showed that erythrocyte sedimentation, interleukin-6, tumor necrosis factor and CD36 fluorescence intensity in monocytes were associated with ankylosing spondylitis, and risk factors for ankylosing spondylitis (P < 0.05). These findings confirm that inflammatory cytokine in patients with ankylosing spondylitis weakened the expression of CD36 in monocytes. There was a remarkable association between low expression of CD36 expression in monocytes and ankylosing spondylitis. CD36 expression of monocytes clinicaly may be considered to be an effective indicator to evaluate inflammation and disease activity in patients with ankylosing spondylitis.

Acute myocardial infarction (AMI) is caused by acute occlusion of the coronary artery. The partial necrosis of the myocardium is caused by severe and prolonged ischemia,which is characterized by persistent and severe chest pain, the high mortality rate. Fast recovery can be achieved the coronary artery blood circulation by emergency percutaneous coronary intervention (PCI), can improve myocardial is-chemia, save moribund myocardium. The medical profession is generally believed that on the basis of en-suring the safety of patients with AMI, the normal rehabilitation should be carried out as soon as possible. In this article, the domestic in recent years, AMI emergency PCI in early postoperative rehabilitation treatment method, the intensity and evaluation index of three aspects were summarized. The starting time of the early rehabilitation of AMI patients in foreign countries is earlier than our country. As we all know that via radial artery PCI has the smaller puncture and more convenient hemostasis, so there is no doubt that it can pro-vide favorable conditions for recovery of patients. Therefore, it is necessary to expand the research field in order to determine the best rehabilitation opportunity and the most excellent rehabilitation program , so as so determine the best recovery time and the most excellent rehabilitation program in patients with AMI after PCI operation.

OBJECTIVETo compare the difference in the clinical efficacy on mild and moderate female stress urinary incontinence (FSUI) between transcutaneous acupoint electrical stimulation and oral administration of midodrine hydrochloride tablets.

METHODSNinety cases of mild and moderate FSUI were randomized into an observation group and a control group, 45 cases in each one. In the observation group, the transcutaneous acupoint electrical stimulation was applied to Ciliao (BL 32), Shenshu (BL 23), Zigong (EX-CA 1), Guanyuan (CV 4) and Qihai (CV 6), once a day. In the control group, midodrine hydrochloride tablets were prescribed for oral administration, 2. 5 mg per treatment, three times each day. The duration of treatment was 4 weeks. The score of international consultation on incontinence questionnaire-urinary incontinence short form (ICI-Q-SF) and leakage of urine in 1 h urinal pad test were observed before and after treatment in the patients of the two groups, and the efficacy was compared between the two groups.

RESULTSThe score of ICI-Q-SF and leakage of urine in urinal pad test after treatment were all improved apparently as compared with those before treatment in the two groups (all P<0. 01), and the results in the observation group were better than those in the control group (both P<0. 01). The total effective rate was 86. 7% (39/45) in the observation group, which was better than 68. 9% (31/45, P<0. 05) in the control group.

CONCLUSIONThe transcutaneous acupoint electrical stimulation achieves the better efficacy on FSUI as compared with the oral administration of midodrine hydrochloride tablets. This therapy effectively improves the patient's urine control ability and reduces leakage of urine.

MicroRNAs (miRNAs) are small non-coding RNAs that contain 22 to 25 nucleotides and play important roles in post-transcriptional regulation of target genes. MiRNAs are involved in cell proliferation, differentiation, apoptosis, inflammation, and cancer development. Alveolar bone resorption is the main clinical manifestation of periodontitis. Osteoclasts are unique cells regulated by osteoblasts and inflammatory cytokines and are responsible for bone resorption in periodontitis. Recently, miRNAs have emerged as an important regulator of osteoclast differentiation and function. In this study, we review the recent research progress on the effects of miRNAs on osteoclast differentiation and function, particularly the mechanisms of miRNAs-mediated osteoclast formation and bone loss in periodontitis.

Objective To study the surgical skills for parasagittal meningioma at the central cortex. Methods A total of 32 patients with parasagittal meningiomas at the central cortex were treated with microsurgery. Through the arachnoid interfaces between the tumor and the brain tissue, the tumor was removed piece by piece. The vein of central sulcus, other draining veins, and normal brain tissues were protected, and the involved sagittal sinus was appropriately treated. Results Simpson Ⅰ, Ⅱ, and Ⅲ grades resection was achieved in 17 (53.1%), 11(34.4%), and 4 (12.5%) of the 32 patients respectively. None of the patients died. Two patients developed cerebral edema and infarction and were cured by surgical decompression. Hemiparalysis was deteriorated in 10 patients, 8 of them recovered spontaneously in 1 to 6 weeks, and the other 2 developed hemiparesis. Among the patients, 21 patients were followed up for 3 months to 5 years. 4 patients had recurrent meningioma in 1 to 3 years after the operation (Ⅱ grade resection in 2 and Ⅲ grade resection in 2). Conclusions For parasagittal meningiomas at the central cortex, preoperation imaging evaluation and microsurgical techniques are key factors for complete resection and surgical outcomes. The vein of central sulcus, other draining veins, and normal brain tissues should be protected during the procedure.
