OBJECTIVETo dicuss the clinical efficacy of Timolol Maleate Eye Drops in the treatment of superficial infantile hemangiomas. Methods From April 2012 to May 2014, 210 patients with superficial infantile hemangiomas were included. According to the parents' choice, a total of 176 cases were treated with Timolol Maleate Eye Drops as the treatment group, and the 34 cases who received the treatment of "wait and see" was included in the control group. In the treatment group, the gauzes were dipped into the eye drops and putted evenly on the surface of the hemangioma, 3-4 times daily and lasted for more than 20 minutes. The gauze should completely cover the surface of the tumor. The follow-up periods were 3 weeks and 6 months after treatment with the pictures to record the treatment effect. The therapeutic effect was graded as: grade I (unable to control the growth of the hemangioma), II (the growth of the hemangioma stagnated), III (hemangioma significantly subsided), IV (the hemangioma completely disappeared). The effective rate included the cases with grade II and above grade II . The cure cases included the cases with grade IV. The data was analyzed with the statistical software SPSS 17.0 and the Chi-square test (P < 0.05).

RESULTS3 cases in the treatment group showed eczema action. Tumor ulcer happened in 1 case in treatment group. The side effect rate was 2.3% . The results at 3 weeks following in the treatment group showed that the growth of the hemangioma were stagnated in 154 cases. The color of hemangioma became darker in different degrees than before, and the texture of the hemangioma became soft in majority of children, and the thickness of hemangioma became thinner in some cases. However, only 4 cases showed the hemangiomas were subsided, 18 cases showed the color of the part of the hemangiomas were brighter than before, and 12 cases of the hemangiomas remained original state in the control group. The results of 6 weeks following the treatment showed that 18 patients in the treatment group reached the standard of the grade IV, 84 patients reached the standard of the grade III, 60 patients achieved in the standard of grade II, and only 14 patients showed the volume of hemangiomas were increased as grade I. The effective rate was 58. 0% , and the cure rate was 10. 2% in treatment group. In control group, no children reached the standard of the grade IV, 4 cases reached the standard of grade III, 13 cases who remained original state reached the standard of grade II, and 17 cases showed the volume of hemangiomas continued to increase as grade I . The effective rate was 11. 8% , and the cure rate was 0. By comparison, the effective rate and the cure rate in the control group were relatively lower than those in the treatment group (P < 0.05).

CONCLUSIONSThe efficacy of Timolol Maleate Eye Drops in the treatment of superficial infantile hemangioma is exact, especially in the proliferative phase of the infantile hemangioma. It is safe and easy to perform with mild side effect. It should be selected as first-line treatment.

Gene knockout by ZFNs (zinc-finger nucleases) is efficient and specific, and successfully applied in more than 10 organisms. Currently, it is unclear whether this technology can be used for knocking-out enhanced green fluorescent protein (EGFP) gene in transgenic goats. Here we constructed and used ZFN-coding plasmids to produce genetic knockouts in the cells of cloned fetus produced from donor cells by microinjection of EGFP gene. Following introduced plasmids into caprine primary cultured fetus fibroblasts by electroporation, targeting of a transgene resulted in sequence mutation. Using the flow cytometric analysis, we confirmed the disappearance of EGFP expression in treated cells. Sequence from PCR products corresponding to targeted site showed that insertion of a G into the exon of EGFP resulted in frame shift mutation. These results suggest that ZFN-mediated gene targeting can apply to caprine fetus fibroblasts, which may open a unique avenue toward the creation of gene knockout goats combining with somatic cell nuclear transfer.

Objective:To illustrate a relatively complete knowledge system (e.g., research outputs, current hotspots, and future trends) in the sepsis field and to help scholars grasp the scientific research direction or clinical focus of treatment.Methods:The relevant literatures of sepsis during the time from 1985 to 2019 in Web of Science database were collected. Sepsis-related research contents were generated using softwares (CiteSpace 5.6.R2 and VOSviewer 1.6.13), which using data mining, information processing and knowledge map methods, to analyze the historical evolution and predict the development trend.Results:A total of 8 189 papers on sepsis were published. The volume of publications were increasing yearly from 1985 to 2019, and reached the top list of 1 276 in 2019. For research contents of sepsis, it has formed the basic characteristics of sepsis which focusing on epidemiological studies and animal experiments. Through cluster analysis, the researches mainly focused on six aspects: septic rat, necrotizingenterocolitis, sepsis-associated encephalopathy, acute kidney injury (AKI), gut-derived sepsis, and inflammatory mediator. And it presented the literature characteristics that related to the injury or dysfunction of intestines, brain, liver, kidney or other organs, but the heart and lung researches were more marginal. Additionally, based on the top key words with the strongest citation bursts, it reflected that the development trend of the continuous attention hotspots with "endotoxin" or "endotoxin shock", the significant attention hotspots with "inflammation", "immunity" and "multiple organ dysfunction syndrome" (MODS), and the novel burst attention hotspots with sepsis management including "diagnosis" and "chemotherapy".Conclusions:Through the hotspots and trends visualization of sepsis, the current researches are prefer to animal experiments, epidemiology, or other basic scientific aspects. Meanwhile, the researches are mostly focusing on inflammatory reaction, immune function or organ dysfunctions. Integrating the knowledge maps of hotspots and trends, based on researches of epidemiology, diagnosis, risk factors, pathogenesis, or treatment, we predict that the future scientific topics will concentrating on childhood sepsis, organ injury mechanism or intervention relating to MODS, and integrated management of sepsis by combining traditional Chinese medicine and Western medicine.

We compared the efficiency of cloning goat using human lactoferrin (hLF) with genetically modified donor cells marked by single (Neo(r)) or double (Neo(r)/GFP) markers. Single marker expression vector (pBLC14) or dual markers expression vector (pAPLM) was delivered to goat fetal fibroblasts (GFF), and then the transgenic GFF was used as donor cells to produce transgenic goats. Respectively, 58.8% (20/34) and 86.7% (26/30) resistant cell lines confirmed the transgenic integration by PCR. Moreover, pAPLM cells lines were subcultured with several passages, only 20% (6/30) cell lines was observed fluorescence from each cell during the cell passage. Somatic cell nuclear transfer using the donor cells harbouring pBLC14 or pAPLM construct, resulting in a total of 806 reconstructed embryos, a pregnancy rate at 35 d (53.8%, 39.1%) and 60 d (26.9%, 21.7%), and an offspring birth rate (1.9%, 1.4%) with 5 and 7 newborn cloned goats, respectively. Transgene was confirmed by PCR and southern-blot in all cloned offspring. There were no significant differences at the reconstructed embryo fusion rates, pregnancy rates and the birth rate (P > 0.05) between single and double markers groups. The Neo(r)/GFP double markers could improve the reliability for accurately and efficiently selecting the genetically modified donor cells. No adverse effect was observed on the efficiency of transgenic goat production by SCNT using somatic cells transfected with double (Neo(r)/GFP) markers vector.

Objective: To understand the cognition and attitudes of men who have sex with men (MSM) towards HIV testing and explore in-depth reasons preventing them from testing. Methods: The function of "opinion" in Blued, a gay geo-social networking application (GSN), was adopted to collect qualitative data of ideas and attitudes towards HIV testing of the users between December 2017 and January 2018. The data was analyzed based on grounded theory approach. Results: 28 269 Blued users participated in the activity and 1 977 posted comments. Four key themes were identified, i.e. no/low risk of contracting HIV, stigmatization of HIV testing, long-term relationship and conventional impediments of HIV testing. Conclusion The cognition and attitudes of the target population derived from the analysis of "opinion" function in Blued, such as the stigmatization of the behavior of HIV testing influencing the attitude of HIV testing, could help researchers build a more accurate detection and promotion strategy instead of a very general intervention on the public.

OBJECTIVEWe sought to master the clinical characteristics and prognosis of hard mental lung disease, improving this disease's diagnosis and treatment quality.

METHODSWe recruited two suspected patients with hard mental lung disease and collected their occupational history, examination results of occupational health, and past medical records. By virtue of laboratory tests, high Kv chest radiography, CT and HRCT of chest, fiberoptic bronchoscopy and ECG examination, diagnostic report was synthesized respectively by respiratory physicians and pathologist from three different agencies. Then the report was submitted to diagnosis organizations of occupational disease, and diagnostic conclusion of occupational disease was drawn after discussion by at least three diagnosticians of occupational disease.

RESULTSWe found that both of the two suspected patients were exposed to dusts of hard metal, and length of exposure service ranged from 8 to 9 years. Clinical manifestations were dominated by dry cough, wheezing after activities, and pathological manifestation was characteristic giant cell interstitial pneumonia. The prognosis and outcome of the disease were different.

CONCLUSIONAccording to exact occupational exposure history, clinical manifestations, combined with the results of high Kv chest radiography, CT of chest and pathological manifestation, it can be diagnosed with hard mental lung disease.
