Congenital pulmonary alveolar proteinosis in a neonate / 中国当代儿科杂志

The male patient was referred to the hospital at 44 days old due to dyspnea after birth and inability to wean off oxygen. His brother died three days after birth due to respiratory failure. The main symptoms observed were respiratory failure, dyspnea, and hypoxemia. A chest CT scan revealed characteristic reduced opacity in both lungs with a "crazy-paving" appearance. The bronchoalveolar lavage fluid (BALF) showed periodic acid-Schiff positive proteinaceous deposits. Genetic testing indicated a compound heterozygous mutation in the ABCA3 gene. The diagnosis for the infant was congenital pulmonary alveolar proteinosis (PAP). Congenital PAP is a significant cause of challenging-to-treat respiratory failure in full-term infants. Therefore, congenital PAP should be considered in infants experiencing persistently difficult-to-treat dyspnea shortly after birth. Early utilization of chest CT scans, BALF pathological examination, and genetic testing may aid in early diagnosis.

Two cases of brucellosis complicated with liver abscess or pancytopenia / 中华全科医师杂志

Two brucellosis patients with rare complications are presented in this report. In case 1, abdominal CT showed two liver abscesses with the maximum diameter>5.0 cm, no puncture and drainage were given. After treatment with anti brucellosis drugs, the abscess lesions disappeared completely. Case 2 had pancytopenia, the platelet count was reduced to 14×10 9/L. After anti brucellosis drug treatment the peripheral blood routine returned to normal. These two cases of rare complications of brucellosis suggests that early identification, diagnosis and treatment can improve the clinical outcomes of the patients.

Application and mechanism of nanomedicine in antifungal infection therapy / 药学学报

The threat of fungal diseases is increasingly rigorous. The clinically invasive fungal infections remain a main cause of morbidity and mortality in certain high-risk groups, especially in critical patients or immunocompromised patients. In drug therapy, the problems of off-target toxicity and antifungal drug resistance are still challenging. With the wide application of biomaterials and nanotechnology, more nanomedicine studies have been carried out on antifungal drugs, such as the amphotericin B liposome which greatly reduced the renal toxicity of drugs has been successfully marketed. For the unique physical and chemical properties, the nano-drug delivery system possessed great potential in improving the bioavailability, reducing the side effects of drugs, increasing the stability of drugs, and achieving cells or tissue-specificity through the modification. This review summarized the applications and limitations of antifungal drugs. Some nanomedicines were summarized in discussion oriented around the antifungal therapy, including liposomes, niosomes, lipid nanoparticles, polymer nanoparticles, microemulsion, dendrimers, inorganic nanocarriers. Nanotechnology and nano-drug delivery system provide promising strategies for the research and development of new formulations that can improve antifungal activity and possibly overcome antifungal drug resistance.

Effects of compound planting on growth and quality of Salvia miltiorrhiza / 中国中药杂志

The effects of four kinds of different plant populations on the morphology, the dry matter accumulation, active ingredient content and antioxidant activty in vitro of Salvia miltiorrhiza were analyzed by setting up four kinds of mixed planting groups, such as S. miltiorrhiza and Cassia obtusifolia, Capsicum annuum, Perilla frutescens and Zea mays. And through the root isolation treatment, we preliminarily explored the formation mechanism of the four kinds of matching plants of the yield and quality of S. miltiorrhiza, and chose the matching plants suitable for the establishment of the compound population with S. miltiorrhiza,and provided the basis for constructing high efficiency compound planting pattern of S. miltiorrhiza. The results showed that there were significant differences in plant morphology, dry matter accumulation of root, active ingredient content and antioxidant activty in vitro of S. miltiorrhiza in different compound population mixed. The growth and yield of S. miltiorrhiza were unfavorable to the combination planting of Cassia obtusifolia, Z. mays and Salvia miltiorrhiza.The compound planting of P. frutescens and S. miltiorrhiza significantly promoted the growth of S. miltiorrhiza, but significantly reduced the quality of S. miltiorrhiza.The yield and quality of S. miltiorrhiza were significantly improved by the combination of C. annuum and S. miltiorrhiza. Therefore, among the four plants of C. obtusifolia, C. annuum, P. frutescens, and Z. mays, the P. frutescens of Solanaceae is the best matching species for the construction of compound planting group with S. miltiorrhiza.

Efficacy and Safety of Teriflunomide in Chinese Patients with Relapsing Forms of Multiple Sclerosis: A Subgroup Analysis of the Phase 3 TOWER Study / 中华医学杂志(英文版)

Background@#Disease-modifying therapy is the standard treatment for patients with multiple sclerosis (MS) in remission. The primary objective of the current analysis was to assess the efficacy and safety of two teriflunomide doses (7 mg and 14 mg) in the subgroup of Chinese patients with relapsing MS included in the TOWER study.@*Methods@#TOWER was a multicenter, multinational, randomized, double-blind, parallel-group (three groups), placebo-controlled study. This subgroup analysis includes 148 Chinese patients randomized to receive either teriflunomide 7 mg (n = 51), teriflunomide 14 mg (n = 43), or placebo (n = 54).@*Results@#Of the 148 patients in the intent-to-treat population, adjusted annualized relapse rates were 0.63 (95% confidence interval [CI]: 0.44, 0.92) in the placebo group, 0.48 (95% CI: 0.33, 0.70) in the teriflunomide 7 mg group, and 0.18 (95% CI: 0.09, 0.36) in the teriflunomide 14 mg group; this corresponded to a significant relative risk reduction in the teriflunomide 14 mg group versus placebo (-71.2%, P = 0.0012). Teriflunomide 14 mg also tended to reduce 12-week confirmed disability worsening by 68.1% compared with placebo (hazard ratio: 0.319, P = 0.1194). There were no differences across all treatment groups in the proportion of patients with treatment-emergent adverse events (TEAEs; 72.2% in the placebo group, 74.5% in the teriflunomide 7 mg group, and 69.8% in the teriflunomide 14 mg group); corresponding proportions for serious adverse events were 11.1%, 3.9%, and 11.6%, respectively. The most frequently reported TEAEs with teriflunomide versus placebo were neutropenia, increased alanine aminotransferase, and hair thinning.@*Conclusions@#Teriflunomide was as effective and safe in the Chinese subpopulation as it was in the overall population of patients in the TOWER trial. Teriflunomide has the potential to meet unmet medical needs for MS patients in China.@*Trial Registration@#ClinicalTrials.gov, NCT00751881; https://clinicaltrials.gov/ct2/show/NCT00751881?term=NCT00751881&rank=1.

The role of IL-22 in T cell reconstitution after thymus damage induced by ionizing radiation / 中华血液学杂志

Objective: To explore the levels of IL-22 in thymus damaged by γ-ray total body irradiation (TBI), and to study the role of IL-22 in T cell reconstitution after thymic injury induced by TBI. Methods: To induce thymic injury, mice were treated by sub-lethal TBI. Levels of intra-thymic and circulatory IL-22 were detected by using ELISA assay. Untreated mice were used as control. After receiving sub-lethal TBI, mice were intraperitoneally injected with PBS or recombinant mouse IL-22, which were marked as TBI+PBS or TBI+IL-22, respectively. Mice were monitored for counts of total thymic cells and circulatory white blood cells. Flow cytometry was applied to analyze percentages of thymic epithelial cells (TEC), thymocyte subsets and circulatory T cells. Real-time PCR assay was applied to analyze the mRNA expression levels of Foxn1, Ccl25, Aire and Dll4 in thymus. Results: ①Sub-lethal TBI treated mice expressed higher levels of intra-thymic and circulatory IL-22, compared with untreated ones (all P<0.05). ②After injection of recombinant IL-22, TBI+IL-22 mice had higher levels of intra-thymic IL-22 than TBI+PBS mice (all P<0.05). ③On day 14 after irradiation, real-time PCR assay showed that TBI+IL-22 mice had higher mRNA levels of Foxn1, Ccl25, Aire and Dll4 in thymus compared with TBI+PBS ones. Meanwhile, the TBI+IL-22 mice had higher counts of total thymic cells[(5.93±3.19)×10(6)/ml vs (1.42±0.46)×10(6)/ml, t=3.128, P=0.033] and circulatory white blood cells[(3.08±0.94)×10(6)/ml vs (1.43±0.30)×10(6)/ml, t=3.730, P=0.015] than those of TBI+PBS mice. Flow cytometry analysis indicated that TBI+IL-22 mice had higher counts of TEC and thymocytes than TBI+PBS mice on day 14 after irradiation (all P<0.05). On days 7 and 14 after irradiation, TBI+IL-22 mice had higher counts of circulatory white blood cells and T cells than TBI+PBS mice (all P<0.05). Conclusion: Sub-lethal TBI induces upregulation of intra-thymic IL-22, and injecting of recombinant IL-22 increases level of IL-22 in thymus. Injecting of recombinant IL-22 improves recovery of TEC and increases numbers of thymocyte subsets and circulatory T cell after thymic injury.

Video versus direct laryngoscopy on successful first-pass endotracheal intubation in ICU patients / 世界急诊医学杂志（英文）

BACKGROUND: Airway management in intensive care unit (ICU) patients is chalenging. The aim of this study was to compare the rate of successful first-pass intubation in the ICU by using the direct laryngoscopy (DL) and that by using the video laryngoscopy (VL). METHODS: A randomized, non-blinded trial comparing first-pass success rate of intubation between VL and DL was performed. Patients were recruited in the period from August 2014 to August 2016. All physicians working at ICU received hands-on training in the use of the video and direct laryngoscope. The primary outcome measure was the first-pass intubation success. RESULTS: A total of 163 ICU patients underwent intubation during the study period (81 patients in VL group and 82 in DL group). The rate of successful first-pass intubation was not significantly different between the VL and the DL group (67.9％ vs. 69.5％,P=0.824). Moreover, the overall intubation success and total number of attempts to achieve intubation success did not differ between the two groups. In patients with successful first-pass intubation, the median duration of the intubation procedure did not differ between the two groups. The Cormack-Lehane grades and the percentage of glottic opening score were similar, and no significant differences were found between the two groups. There were no statistical differences between the VL and the DL group in intubation complications (all P>0.05). CONCLUSION: Among ICU patients requiring intubation, there was no significant difference in the rate of successful first-pass intubation between VL and DL.
