Objective:To study the effects of comprehensive warming intervention strategy on the body temperature of preterm infants (gestational age <32 weeks and birth weight <1 500 g) during inter-hospital transportation.Method:From October 2016 to July 2019, eligible preterm infants transported to our hospital were retrospectively analyzed. From October 2016 to March 2018, preterm infants transported with routine transportation strategy were assigned into the control group. From April 2018 to July 2019, preterm infants transported with the comprehensive warming intervention strategy were assigned into the experiment group. The body temperature, complications and prognosis before and after the transportation to our NICU were compared.Result:A total of 1 194 premature infants with gestational age <32 weeks were included with 630 cases in the control group and 564 cases in the experiment group. No significant differences existed in demographic data of the mothers, infants and the transportation time between the two groups ( P>0.05). The body temperatures before and after transportation in the experimental group were (36.8±0.5)℃ and (36.7±0.5)℃, significantly higher than the control group [(36.0±0.4)℃ and (36.3±0.6)℃] ( P<0.01). The incidences of hypoglycemia and mortality in the experimental group were 3.7% (21/564) and 4.8% (27/564), significantly lower than the control group [8.4% (53/630) and 7.9% (50/630)] ( P<0.05). Conclusion:Comprehensive warming intervention strategy in inter-hospital transport can effectively improve the body temperature of preterm infants before and after transportation, reducing the incidences of hypoglycemia and mortality.

Study on the relationship between thyroid imaging reporting and data system and the Bethesda system for reporting thyroid cytopathology / 中国医师进修杂志

Objective To compare effect between thyroid imaging reporting and data system (TI-RADS) and the Bethesda system for reporting thyroid cytopathology (TBSRTC) in the qualitative diagnosis of thyroid nodule. Methods The clinical data of 665 patients with thyroid nodule (1 598 nodules) from April 2013 to October 2016 were retrospectively analyzed. TBSRTC and TI-RADS were used for qualitative diagnosis of thyroid nodule before operation. Pathological diagnosis was performed after the operation. The diagnostic effect of TI-RADS and TBSRTC were assessed, and the factors leading to the diagnostic errors were analyzed. Results Of 1 598 thyroid nodules, the pathological diagnosis showed that benign nodules were in 202, and malignant thyroid nodules were in 1 396. The diagnostic sensitivity and 85.64%(173/202) vs. 74.75%(151/202) and specificity of malignant nodules by TBSRTC were significantly higher than that by TI-RADS: 91.76% (1 281/1 396) vs. 87.11% (1 216/1 396), and there was statistical difference (P＜0.01). The diagnosis positive rate of malignant nodules with diameter＜1 cm by TBSRTC was significantly higher than that by TI-RADS: 77.63% (59/76) vs. 47.37% (36/76), and there was statistical difference (P＜0.01); there was no statistical difference in diagnosis positive rate of malignant nodules with diameter ≥ 1 cm between 2 methods (P＞0.05). Univariate analysis result showed that the diameter of thyroid nodules in patients with TI-RADS false negative was significantly smaller than that in patients with benign thyroid nodules: (1.01 ± 0.48) cm vs. (1.51 ± 0.45) cm, the incidence of malignant thyroid nodules combined with other thyroid diseases was significantly higher than that in patients with benign thyroid nodules: 41.18% (21/51) vs. 11.32% (158/1 396), and there were statistical differences (P＜0.05); the rate of thyroid dysfunction in patients with TBSRTC false positive was significantly higher than that in patients with malignant thyroid nodules: 18.26% (21/115) vs. 6.93% (14/202), and there was statistical difference (P＜0.05). Conclusions The qualitative diagnosis of thyroid nodule requires the cross-reference of TI-RADS and TBSRTC, and the combination of other clinical indicators of patients can improve the detection rate of malignant thyroid nodules.

Clinical diagnostic performance of the simultaneous amplification and testing methods for detection of the Mycobacterium tuberculosis complex for smear-negative or sputum-scarce pulmonary tuberculosis in China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Early detection of pulmonary tuberculosis (PTB) is a big challenge in smear negative and sputum scarce patients in China. Simultaneous amplification and testing methods for detection of the Mycobacterium tuberculosis (MTB) complex (SAT-TB assay) is a novel molecular technique established in our hospital. This method has a high sensitivity and specificity in the lab. In this study, the clinical diagnostic performance of this method in smear-negative or sputum-scarce PTB suspects was investigated and evaluated.</p><p><b>METHODS</b>Two hundred smear negative and 80 sputum-scarce patients were recruited in this study. Samples that included sputum or bronchial washing fluid were collected and sent for both bacteria culture and SAT-TB assay. Diagnosis for these patients was based on the comprehensive evaluation of chestX- ray/CT study, histology examination, lab results, and treatment response. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for each diagnostic test were investigated and calculated using confirmed tuberculosis (TB) and non-TB cases. The time required for detection of MTB was also measured for each method.</p><p><b>RESULTS</b>Ninety-two patients (33%) were diagnosed as definitive TB, 112 patients (40%) were probable PTB, and 76 (27%) were non-TB. The sensitivity, specificity, PPV, and NPV of SAT-TB in smear-negative PTB suspects were 93% (95% CI, 84%-98%), 98% (95% CI, 90%-100%), 98% (95% CI, 91%-100%), and 93% (95% CI, 83%-98%). In sputum scarce PTB suspects, the sensitivity, specificity, PPV, and NPV of the SAT-TB assay on bronchial washing fluids were 90% (95% CI, 74%-98%), 100% (95% CI, 85%-100%), 100% (95% CI, 88%-100%), and 88% (95% CI, 69%-97%). The accuracy of the SAT-TB assay is consistent with the bacteria culture assay. The median time required for detecting MTB in the SAT-TB assay was 0.5 day, which was much faster than bacteria culture (28 days).</p><p><b>CONCLUSIONS</b>The SAT-TB assay is a fast and accurate method for the detection of MTB. It can be widely applied in the clinic and be an asset in early detection and management of PTB suspects, especially in those patients who are smear negative or sputum scarce.</p>

Sulfonation of polyethersulfone sheets effects on adsorbability of beta 2-microglobulin: Whether the adsorbability changes with increased sulfonation degree? / 中国组织工程研究

BACKGROUND: Dialysis-related amyloid may occur during long-term dialysis for patients with uraemia, of which the main evocator is β_2-microglobulin (β_22M); therefore, how to eliminate 132M from blood is always the focus of research. OBJECTIVE: To observe ability of removal of β_2-microglobulin (β_2M) from serum using two kinds of polyethersulfone (PES) membrane materials with various degrees of sulfonation.METHODS: These materials were incubated in radio-labeled β_2M (~(125)Ⅰ-β_2M) solution and human serum respectively at appointed time at 37 ℃, and then the amounts of ~(125)Ⅰ-β_2M and serumβ_2M adsorbed by materials were measured by radio immunoassay. RESULTS AND CONCLUSION: In the ~(125)Ⅰ-β_2M system, amounts of ~(125)Ⅰ-β_2M adsorbed by the materials decreased in the following sequence PES with high degree of sulfonation > PES with low degree of sulfonation > PES, whatever the source of PES was. In the serum system, amounts of β_2M adsorbed reached maximums at 30 minutes and the final adsorptions decreased in sequence of PES with high degree of sulfonation > PES with low degree of sulfonaUon > PES. Sulfonated PES removed β_2M more than PES did and the adsorption of β_2M increases with the increase in the degree of sulfonation. Its ability to remove significant amount of β_2M may result in less β_2M available for incorporation into amyloid. The use of sulfonated PES membranes may lessen the likelihood of development of dialysis-related amyloidosis, which remains a major source of morbidity for patients treated with long-term hemodialysis.

Effect of sulfonation of polyethersulfone sheets on the adsorption of beta2-microglobulin / 生物医学工程学杂志

This study was performed to evaluate the adsorption of beta2-microglobulin(beta2 M) by blood dialysis membrane materials which are polyethersulfone (PES), sulfonated polyethersulfones, (PES-SO3Na-I and PES-SO3Na-I ) in vitro incubated in human serum and radiolabeled beta2M (125I-beta2 M) solution respectively. In these experiments, the materials were incubated in 125I-beta2 M solution and human serum at the appointed time ranging from 15 minutes to four hours at 37 degrees C, and then the amounts of 125I-beta2M and serum beta2M adsorbed by materials were measured by radioimmunoassay (RIA). In the 125I-beta2 M system, amounts of 125I-beta2M adsorbed by the materials decreased in sequence of PES-SO3 Na-II > PES-SO3Na-I > PES. In the serum system, amounts of beta2M adsorbed reached maximums at 30 minutes and the final adsorptions decreased in sequence of PES-SO3Na-II > PES-SO3Na-I > PES. Sulfonated PES removes beta2M more than PES does and the adsorption of beta2M increases with the increase in the degree of sulfonation. Its ability to remove significant amount of beta2M may result in less beta2M available for incorporation into amyloid. The use of PES-SO3Na membranes lessens the likelihood of dialysis-related amyloidosis (DRA) development, which remains a major source of morbidity for patients treated with long-term hemodialysis.
