Methods 123 cases (including mild 26.67 kPa2/FiO₂≤40.00 kPa,PEEP or CPAP≥0.49 kPa,moderate 13.33 kPa 2/FiO₂≤26.67 kPa,PEEP≥0.49 kPa and severe PaO₂/FiO₂≤13.33 kPa,PEEP≥0.49 kPa)of patients with acute respiratory distress syndrome and 41 cases of non-ARDS were involved. from January 2016 to January 2018 in our hospital and 41 cases of healthy people by routine check-up in our hospital during the same period were selected,then the serum thyroid hormone levels were determined. Results Compared with healthy control group,TSH、FT4、TT4、FTS、TT3 level in non-ARDS group has no statistical difference(P＞0.05),while compared with the rest of the two groups,all indexes in ARDS group were lower (P＜0.05). And TSH、FT4、TT4、FT3、TT3 levels in moderate ARDS group decreased compared with those in relatively mild ARDS (P＜0.05). The level of each index in severe ARDS group decreased compared with the moderate ARDS group (P＜0.05). There was statistical difference in detection index level in three groups. Conclusion The serum thyroid hormone level of ARDS patients is positively correlated with hypoxemia. As the pathological severity changes ,the level of hypoxemia changes are more apparent. Dynamic monitoring of serum thyroid hormone is of great significance in severity judgement and prognosis evaluation.

Objective To investigate the correlation between change characteristics of pregnant genital tract flora and adverse pregnancy outcomes. Methods 90 pregnant women received routine obstetric examination in our obstetrics and gynecology of hospital from January 2015 to September 2015 were selected as research object. According to duration of pregnancy, they were divided into 28 cases of early pregnancy group (gestational weeks<14 weeks), 29 cases of middle pregnancy group (14~28 weeks) and 33 cases of late pregnancy group (29~42 weeks). The vaginal or cervical secretions were collected, and genital tract flora was detected. The genital tract flora distribution of three groups were compared. According to bacteria detection results, patients were divided into 44 cases of positive group and 46 cases of negative group. The adverse pregnancy outcomes of two groups were observed, and the correlation between change characteristics of pregnant genital tract flora and adverse pregnancy outcomes was analyzed. Results Among 90 pregnant women, there were 44 cases of positive bacteria (48.89%), which included 20 cases of ureaplasma urealyticum(45.45%), 9 cases of Candida (20.45%), 8 cases of enterobacter (18.18%), 3 cases of staphylococcus (6.82%), 2 cases of vaginal gardnerella (4.55%) and 2 cases of chlamydia (4.55%); There was no statistical difference in the genital tract flora distribution among early, middle, late pregnancy group (P>0.05); The incidence of premature rupture of membrane, puerperal infection, neonatal infection and premature birth in patients with positive bacteria was higher than that in patients with negative bacteria (P<0.05); There was no statistical difference in the adverse pregnancy outcomes in patients with different types of bacterial genus (P>0.05). Conclusion Pregnant genital tract flora are mainly ureaplasma urealyticum, candida and enterobacter, and the incidence of adverse pregnancy outcomes in patients with positive bacteria is higher, but different types of bacterial genus has no correlation with adverse pregnancy outcomes.

Objective To assess the 25-hydroxyvitamin D (25-OH-D) and interleukin-17(IL-17) status in patients with systemic lupus erythematosus(SLE) and its clinical significance. Methods 40 SLE patients along with 20 matched controls were collected. Chemilumineseent immunoassay (CLIA) was used to detect the levers of serum 25-OH-D. The levels of serum IL-17 were evaluated using enzyme-linked immunosorbent assay (ELISA). Results Serum 25-OH-D level in SLE patients was significantly lower than in healthy controls (P<0.01). Serum 25-OH-D level in active SLE patients was significantly lower than in inactive SLE patients (P<0.01). Lever of IL-17 was significantly higher in SLE patients than in healthy controls (P<0.01). Insufficiency of 25-OH-D was related to renal disorders. Serum 25-OH-D level was negatively correlated with systemic lupus erythematosus disease activity index (SLEDAI) scores(r=-0.844, P<0.01)and serum levels of IL-17(r=-0.596, P<0.01). Conclusion Insufficiency of 25-OH-D is prevalent in SLE patients. It is associated with nephritis, disease activity and high serum levels of IL-17, thus it may play an important part in the inflammatory process in SLE.

Objective Discussion about value of brain natriuretic peptide (BNP) in helping to determine the efficacy and prognostic of pulmonary tuberculosis combine with respiratory failure. Methods 81 cases were admitted from January 2013 to December 2014 in our hospital of early treatment sputum positive pulmonary tuberculosis with respiratory failure. And the cases were carried out BNP, arterial blood gas analysis and chest X-ray before treatment and after two weeks respectively.104 cases of earlier sputum positive pulmonary tuberculosis accompanied with respiratory failure were randomly drawn according to the corresponding random number of hospitalization as a control group. Two sets of data were collected to conduct retrospective case-control study. Results BNP of pulmonary tuberculosis combine with respiratory failure is 11.4 times higher than that of tuberculosis alone (1115.11 pg/mL compare 97.60 pg/mL), the whole TB is 3.4 times higher than non-full-tuberculosis (1549.82 pg/mL t compare 449.47 pg/mL). Before treatment, BNP was negatively correlated to PaO₂, SaO₂ and pH BNP was positively correlated with PaCO₂. There was no correlation after treatment between BNP and PaCO₂.After two weeks BNP is 0.57 times of the pre-treatment (632.41 pg/mL compared 1115.11 pg/mL). The group of death is 8.7 times higher than the survival group (3119.63 pg/mL compared 359.84 pg/mL). Conclusion BNP was significantly increased in patient accompanied tuberculosis with respiratory failure .The condition is continued to decline after treatment. There is likely to be one of the indicators of helping to determine the efficacy and estimate prognosis.

Objective To discuss the effect of electromyographic biofeedback on cerebral hemodynamics in health people. Methods A total of 30 healthy volunteers were enrolled in this study, and randomly divided into biofeedback group (n=20) and control group (n=10). The biofeedback group had been done with electromyographic biofeedback for seven times with 3 days intervals after each test. The data including the mean velocity (Vm) and pulse index (PI) of anterior cerebral artery, middle cerebral artery (MCA) and posterior cerebral artery were collected bilaterally before and after the test using transcranial Doppler in the two groups. Results The values of Vm (P<0.05) were higher and PI (P<0.05) were lower in biofeedback group than those in control group before and after the test. The values of Vm (P<0.05) increased and PI (P<0.05) decreased gradually in biofeedback group from 1st to 7th tests. Conclusion The electromyographic biofeedback can induce to the increasing of velocity of cerebral blood flow and decreasing of PI in MCA, and the additive effect was observed during the 7 tests in biofeedback group.
