Objective To investigate the security of mechanical filter in mechanical ventilation for ICU patients.Methods 60 patients treated with mechanical ventilation and conventional airway humidification were selected and randomly divided into treatment group(mechanical filter treatment) and control group(non filter treatment) ,30 cases in each group.The changes of respiratory function(airway plateau pressure,endogenous PEEP and arterial carbon dioxide partial pressure of 2h,12h,24h at the first day of mechanical ventilation) ,and the incidence and mortality of ventilator-associated pneumonia were observed.Results The study showed airway resistance and the work of breathing in treatment group did not increase,and no hypercapnia due to congestion occurred.The incidence of ventilator-associated pneumonia in treatment group was significantly lower than that of the control group (26.7% vs 56.7% ,x2 = 5.554,P = 0.018).Conclusion Mechanical filer applied in patients with mechanical ventilation was safe and could decrease the incidence of ventilator-associated pneumonia.

Monolithic silica spin column extraction (MonoSpin-SPE) was developed as a simple,sensitive,and eco-friendly pretreatment method which combined with ultra-fast liquid chromatography-mass spectrometry (UFLC-MS) to determine the levels of six phthalate esters,dimethyl-(DMP),diethyl-(DEP),dipropyl-[DPrP],butyl-benzyl-(BBP),dicyclohexyl(DcHP),and di-n-octyl-(DOP) phthalate in physiological saline samples.Under optimized experimental conditions,the method was linear in the following ranges:0.2 - 50 μg/L for DMP,DEP,DPrP,DcHP and DOP; 5- 100,μg/L for BBP.The correlation coefficients (R2 ) were in the range of 0.9951- 0.9995 for all the analytes and the limits of detection (LODs) and limits of quantification (LOQs) were in the ranges of 0.02- 0.9 μg/L and 0.08- 2.7 μg/L,respectively.The pretreatment process showed good reproducibility with inter-day and intra-day relative standard deviations (RSDs) below 8.5％ and 11.2％,respectively.This method was used to determine the levels of six phthalate esters in physiological saline samples and the recoveries ranged from 71.2％ to 107.3％.DMP and DEP were found in actual physical saline samples (brand A and brand B).

After the development of different medical social media in China was summarized , the advantages and trend of social media in medical field of China were analyzed , the challenges facing medical social media were pointed out and their countermeasures were proposed .

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

Objective To investigate T cell receptor(TCR)variable β(BV)chain usage at the maternal-fetal interface and explore the relationship between the skewed TCR BV usage and unexplained recurrent spontaneous abortion(BSA).Methods Eighteen cases with unexplained RSA,together with matched 41 women with normal pregnancies in first trimester from Renji Hospital,Shanghai Jiao Tong University were studied.A high-resolution spectrum typing analysis of complementarity-determining region 3 (CDR3)was used to detect and compare the degree and frequency of TCR BV family expression in deciduas between RSA patients and normal controls.Results(1)The expression degree of BV19(0.029±0.031 vs.0.013±0.010,P=0.038)in RSA group showed a higher usage,while BV5.2(0.040±0.035 vs.0.067±0.052,P=0.046)showed a significantly lower usage when compared with normal controls.No significant difference in the expression of the other TCR BV families between RSA and controls were observed(P>0.05).(2),TCR BV2,3,6,and 7 were the four most common BV families in deciduas of patients with RSA and normal controls,whose frequencies were all mors than 50%.In RSA group,higher frequencies of BV15 (33.3%vs.7.3%,P=0.018),BV19(38.9%vs.14.6%,P=0.049)and BV20(33.3%vs.7.3%,P=0.018)were observed;meanuhile lower frequencies of BV4(33.3%vs.65.9%,P=0.026)and BV7 (66.7%vs.92.7%.P=0.018)distributions were observed.The other TCR BV families did not display significantly different freqencies of distribution(P>0.05).Conclusions It is suggested that a significant skewed TCR BV family occurs at the maternal-fetal interface in patients who undergo abortion.The specific skewed usages of TCR BV might be associated with the susceptibility to unexplained pregnancy loss.

Objective To study the incidence of low triiodothyronine (T3) syndrome in critical patients,and compare the prognosis evaluation value between low T3 syndrome and acute physiology and chronic health evaluation (APACHE) Ⅱ score.Methods A total of 160 critical patients were enrolled.APACHE Ⅱ score of patients were recorded at admission,and thyroid hormone levels were measured on the first and the third day after admission.The patients who were low T3 level were enrolled into observation group,and the patients who were normal T3 level were as control group.The patients were followed up for 28 d,then were divided into death group and survival group according to the prognosis.The prognosis evaluation value was compared between T3 and APACHE Ⅱ score by receiver operating characteristic (ROC) curve.Results The incidence rate of low T3 syndrome was 25.6％ (41/160).During the follow-up phase,the fatality rate in observation group was 41.5％(17/41),and in control group was 29.4％ (35/119),there was statistical difference (P ＜ 0.05).The ROC area under curve of T3 was 0.657 (95％ CI:0.712-0.846),APACHE Ⅱ score was 0.672 (95％ CI:0.721-0.857),and there was no statistical difference (P ＞ 0.05).Best cut-off value of T3 was 0.41 μ g/L resulting in 76.9％(40/52) sensitivity and 78.7％(85/108) specificity.Conclusion Critical patients complicated with low T3 syndrome has poor prognosis,and T3 may be a predictive marker in evaluating the prognosis of critical patients.

Aim: To prepare the influenza vaccine lyophilized liposomes and to characterize its particle distribution, encapsulation efficiency and immunogenicity. Methods: Flu vaccine liposome based on the method of thin-film evaporation was prepared using phospholipids , cholesterol and the purified influenza virus split vaccine, and was further subjected to frozen-drying. The polymorph was observed by microscope; the particle distribution and the average size were analysed by transmission electron microscope; its encapsulation efficiency was determined by Lowry method and the antibody titers were assessed by hemagglutination-inhibition after pulmonary delivery to mice. Results: The reconstitated influenza vaccine liposome under electronic microscope were round or elliptic particles evenly distributed at a mean size of 2. 14 祄, with the encapsulation efficiency of more than 80%. The antibody titer through pulmonary delivery was higher than that through intraperitoneal injection. Conclusion: The prepared influenza vaccine lyophilized liposomes possess high encapsulation efficiency, better particle distribution and marked immunogenicity through pulmonary delivery to mice. Pulmonary delivery of influenza vaccine liposomes is a potential immunization approach worthy of further exploitation.
