Based on the special environment of high-altitude areas and the characteristics of post-disaster medicines de-mand,this article discussed the difficulties and management strategies for post-earthquake emergency medicines support.Natural conditions such as low temperature,dryness and ultraviolet radiation in high-altitude areas,as well as problems such as weak transportation infrastructure and shortage of medical resources,have posed huge challenges to the stability,transportation,supply,distribution and use of the medicines.Therefore,this paper suggested solutions such as diversified supply channels,transportation reinforcement,temperature and humidity control,light protection measures,sand and corrosion prevention,proposed precautions such as medicine distribution on demand,rational use and strengthening of pharmaceutical care,also emphasized that local cultur-al habits should be respected.Furthermore,according to high-altitude areas environmental characteristics and different rescue sta-ges(emergency period,sub-emergency period,recovery period),the corresponding emergency medicines catalog was recommen-ded.The study aims to provide scientific basis and practical guidance for the medicine supply of earthquake in plateau,improve rescue efficiency,and reduce disaster losses.

Psoriasis, a chronic, immune-mediated inflammatory disease characterized by hyperproliferation of keratinocytes, is difficult to cure and prone to relapse, often leading to systemic damage. Triptolide (TPL) can modulate cutaneous immune responses and inflammation, yet its therapeutic window is narrow with significant toxicity. To enhance skin targeting and retention of TPL while reducing systemic absorption and toxicity, a TPL/hyaluronic acid/phospholipid polymeric micelle (TPL/HA-DOPE) was constructed via HA's targeting of the CD44 receptor on skin cells. The prepared TPL/HA-DOPE exhibited a uniform spherical morphology with particle size of (130.4±1.23) nm, drug loading capacity of (19.74±0.084) %, and encapsulation efficiency of (85.53±1.34) %. Transdermal permeation studies in vitro and in vivo demonstrated that TPL/HA-DOPE not only enhanced uptake in HaCaT cells but also exhibited excellent skin retention. In a murine model of psoriasis, the TPL/HA-DOPE gel at the dose of 50 μg/(kg•d) showed the most significant improvement in erythema, scaling, and epidermal thickening. Histological analysis confirmed that TPL/HA-DOPE markedly reduced stratum corneum thickness, epidermal hyperplasia, and inflammatory cell infiltration. Ki67 immunostaining proved that its anti-inflammatory mechanism might be achieved by reducing the number of Ki67-positive cells and lowering the levels of inflammatory factors IL-6 and TNF-α. The above results demonstrate that HA-DOPE as a drug delivery carrier for the treatment of psoriasis-like skin diseases has high value of scientific research and good prospects for clinical application.

Objective: To investigate the expression of HOXA13 in non-small cell lung cancer (NSCLC) tissues, and to explore the effect of silencing HOXA13 gene on the growth of A549 cells in vitro and xenograft in nude mice. Methods: A total of 112 pairs of NSCLC tissues and corresponding adjacent normal tissues from patients, who underwent surgical resection at the Department of Thoracic surgery, Central Hospital of Jiaozuo Coal Industry Group from March 2014 toApril 2016, were selected for this study. Real-time fluorescence quantitative PCR was used to detect the expressions of HOXA13 in NSCLC tissues and adjacent tissues. A549 cells were cultured and divided into siRNA-HOXA13 group, negative control group and control group. Real-time quantitative PCR was used to detect the expression of HOXA13 in cells, CCK-8 was used to detect cell proliferation, and Transwell assay was used to detect cell invasion. Xenograft model in nude mice was constructed, and the growth of nude mice was observed.After 5 weeks, the mice was sacrificed and weighed, and the tumor-inhibition rate was calculated. Real-time fluorescence quantitative PCR(qPCR) was used to detect the expression of HOXA13 in xenograft tissues. Results: The relative expression level of HOXA13 mRNAin NSCLC tissues was significantly higher than that in the adjacent tissues (1.83±0.13 vs 1.12±0.10, t=47.008, P=0.000), and its expression was correlated to TNM staging, differentiation and lymph node metastasis (all P<0.05). The relative expression level of HOXA13 mRNA in cells of siRNAHOXA13 group was lower than that in the negative control group and the control group (P<0.05). The cell proliferation level (D values) at 24, 48, 72 and 96 h in the siRNA-HOXA13 group were significantly lower than those in the negative control group and control group (F=30.727, 5.427, 13.816 and 24.454, all P<0.05 or P<0.01); the number of invasive cells in the siRNA-HOXA13 group was lower than that in the negative control group and the control group (all P<0.05). The mass of xenograft in nude mice at week 5 in the siRNA-HOXA13 group was smaller than that in the negative control group and control group, while the tumor-inhibition rate was higher than the negative control group (all P<0.05). The relative mRNA expression level of HOXA13 in xenograft tumor tissue in the siRNA-HOXA13 group was lower than that in the negative control group and the control group (all P<0.01). Conclusion: HOXA13 was highly expressed in the non-small cell lung cancer tissues, and was related to oncogenesis, progression and metastasis of cancer. Specific silencing of HOXA13 gene expression could inhibit the proliferation and invasion of tumor cells and suppress the growth of xenograft in nude mice.

Objective: To establish comprehensive laboratory reference intervals for Chinese children. Methods: This was a cross-sectional multicenter study. From June 2013 to December 2014, eligible healthy children aged from 6-month to 17-year were enrolled from 20 medical centers with informed consent. They were assessed by physical examination, questionnaire survey and abdominal ultrasound for eligibility. Fasting blood samples were collected and delivered to central laboratory. Measurements of 15 clinical laboratory parameters were performed, including estradiol (E2), testosterone(T), luteinizing hormone(LH), follicle-stimulating hormone(FSH), alanine transaminase(ALT), serum creatinine(Scr), cystatin C, immunoglobulin A(IgA), immunoglobulin G(IgG), immunoglobulin M(IgM), complement (C3, C4), alkaline phosphatase(ALP), uric acid(UA) and creatine kinase(CK). Reference intervals were established according to central 95% confidence intervals for reference population, stratified by age and sex. Results: In total, 2 259 children were enrolled. Finally, 1 648 children were eligible for this study, including 830 boys and 818 girls, at a mean age of 7.4 years. Age- and sex- specific reference intervals have been established for the parameters. Reference intervals of sex hormones increased gradually with age. Concentrations of ALT, cystatin C, ALP and CK were higher in children under 2 years old. Serum levels of sex hormones, creatinine, immunoglobin, CK, ALP and urea increased rapidly in adolescence, with significant sex difference. In addition, reference intervals were variable depending on assay methods. Concentrations of ALT detected by reagents with pyridoxal 5'-phosphate(PLP) were higher than those detected by reagents without PLP. Compared with enzymatic method, Jaffe assay always got higher results of serum creatinine, especially in children younger than 9 years old. Conclusion This study established age- and sex- specific reference intervals, for 15 clinical laboratory parameters based on defined healthy children.

Objective]The aim of this study was to investigate the level of serum C3,C4 and HDL-C in patients with coronary heart disease and the correlation between C3,C4 and HDL-C in patients with coronary heart disease.[Methods]We collected 251 cases of patient diagnosed with coronary artery disease by coronary angiography in Sun Yat-sen Memorial Hospital ,Sun Yat-Sen University from 2015-12 to 2016-07 and collected over our Boji Medical Center healthy people in 214 cases. These patients were divided into acute coronary syndrome group with 180 cases and stable coronary heart disease group with 71 cases. Each test results was adopted from clinical laboratory of Sun Yat-Sen Memorial Hospital ,Sun Yat-Sen University.[Results]Compared with the healthy control ,the difference of serum C3,C4 and HDL-C from acute coronary syndrome group and stable coronary heart disease group,was statistically significant(P<0.05). However,in patients with acute coronary syndrome and stable coronary artery disease groups,there was no significant correlation(P > 0.05)between C3,C4 and HDL-C. In healthy group,complement C3 negatively correlated with HDL-C,the difference was statistically significant(P<0.05).[Conclusions]In patients with coronary heart disease, the level of C3 and C4 increased,while the level of HDL-C decreased ,and inflammation may affect the relevance judgments between complement and HDL-C.

Objective To investigate the curative effects and adverse reactions of pure radiotherapy and concurrent chemotherapy and radiotherapy for patients with cervical cancer.Methods One hundred and twenty-seven patients with cervical cancer who accepted treatment in the Affliated Hospital of Inner Mongolia Medical Unive.rsity from May 2010 to May 2012 were collected.All patients were divided into two groups:pure radiotherapy group (n =65) and concurrent chemotherapy and radiotherapy group (n =62).The curative effects,adverse reactions and survival of two groups were observed.Results All patients were completed treatment.The median follow-up time was 42 months.The rate of complete response in the pure radiotherapy group was 80.0％ (52/65),and the rate in the concurrent chemotherapy and radiotherapy group was 82.26％ (51/62),with no significant difference (x2 =1.22,P =0.352).The 1-year overall survival rates in the pure radiotherapy group and the concurrent chemotherapy and radiotherapy group were 95.38％ and 95.16％ respectively,with no significant difference (x2 =0.32,P =0.533),but the 3-year overall survival rates were 81.54％ and 90.32％ respectively,the 5-year overall survival rates were 72.31％ and 83.87％ respectively,with significant differences (x2 =5.09,P =0.015;x2=3.87,P =0.039).However,for the patients who were ≥ 60 years,the 1-year overall survival rates in the two groups were 94.62％ and 93.91％ respectively,the 3-year overall survival rates were 85.02％ and 87.25％ respectively,the 5-year overall survival rates were 70.06％ and 73.58％ respectively,with no significant differences (x2 =0.06,P =0.753;x2 =1.16,P =0.279;x2 =0.48,P =0.511).The adverse reactions were mainly in grades 1-2.There were significant differences in the rates of leucopenia (56.10％ vs.72.20％),thrombocytopenia (58.82％ vs.76.80％),nausea and vomiting (34.04％ vs.56.90％) among the two treatment groups (x2 =11.23,P =0.003;x2 =11.82,P=0.002;x2 =12.77,P =0.000).Conclusion The curative effect of concurrent chemotherapy and radiotherapy is better than that with pure radiotherapy for patients with cervical cancer,which can improve the 3-year and 5-year overall survival.But at the same time,it should be noted that the rates of adverse reactions may be increased during the same period.For the age of 60 or more patients with cervical cancer,concurrent chemotherapy and radiotherapy does not achieve even greater survival benefit.

The present case report was designed to summarize the clinical experience of operative technique. lung preservation, lung perfusion, and perioperative management. Of 7 cases who underwent allogenic single lung transplantation (LT), 3 were idiopathic pulmonary fibrosis, 2 were chronic obstructive pulmonary disease, 1 was silicosis, emphysema, and bulla, and I was tuberculosis in both sides and presented with destroyed lung in one side. All donors were already brain death. Donor lungs were well preserved utilizing Euro-Colins liquid or low-potassium dextran solution. Donors and recipients were matched in blood type. Of 7 cases selected,5 received single right lung transplantation, and 2 received single left LT. End-to-end anastomosis was performed for pulmonary branches and pulmonary arteries. while atrium-to-atrium anastomosis was performed for pulmonary vein. Antibiotics and immunosuppressants were routinely used prior to and subsequent to LT. Following LT, heart and lung function, usage of antibiotics, and adjustment of immunosuppressant were monitored. Stomal complications regarding bronchus and pulmonary artery and vein did not appear in any patient. Five cases survived for about 2 months, one for approximately 1 year, and one for nearly 2 years. Four cases died of multi-organ failure caused by pulmonary infection, and one of severe pulmonary hemorrhage caused by aspergillus sydowi infection. Rejection occurred in 6 cases. One case sufiered from rejection three times. Selection of indication, selection and preservafton of donor lung, LT operation and pre-and post-operative management of LT have acquired satisfactory achievements. High mortality occurred in patients with preoperative poor cardiac and pulmonary functions and postoperative severe infections accompany with application of immunosuppressant.
