Objective To summarize the experience of examination and treatment of 237 cases of eye diseases with portable slit lamp in earthquake area of Dujiangyan, Sichuan Province, from May 14 to July 8, 2008. Methods 237 cases of the eye diseases were examined and diagnosed. With portable slit lamp, the foreign bodies in 25 cases of conjunctival foreign body and 62 cases of corneal foreign body were removed. Results Of the 237 cases, 39 were diagnosed as conjunctivitis, 25 as conjunctival foreign body, 13 as pterygium, 27 as keratitis, 11 as corneal ulcer, 62 as cornea foreign body, 24 as cornea injury, 7 as hyphema, 16 as iridocyclitis, 5 as glaucoma and 8 as cataract. With portable slit lamp, the foreign bodies in 25 cases of conjunctival foreign body and 62 cases of corneal foreign body were removed in one lump with no corneal perforation or infection. Follow-up examination showed that the wounded cornea repaired pretty well. Conclusions With portable slit lamp, ophthalmologists can not only make a precise diagnosis for the eye diseases in the anterior segment, but also are able to timely to remove foreign bodies in conjunctiva and cornea. Portable slit lamp is a useful and convenient instrument for ophthalmologists in the field of earthquake disaster relief.

Diabetic macular edema (DME) is a leading cause of vision loss in diabetic patients.It is very important to correctly select a treating approach for DME.At present,the treating methods of DME include retinal laser photocoagulation,application of the glucocorticoid,intravitreous injection of anti-vascular endothelial growth factor (VEGF) drugs,administration of inhibitor of protein kinase C,vitrectomy and combined treatment etc.However,each method has its advantage and disadvantage.Retinal photocoagulation,vitrectomy,intravitreous injection and drug delivery system implantation are invasive treatment methods,and they can not rescue damaged retinal photoreceptors.Therefore,it is recommended that DME should be early diagnosed and effective treatment.The research status at home and abroad and future development trends of DME treatment were summarized.

The Her-2 proto-oncogene encodes a 185kDa transmenbrane glycoprotein p185 which has intrinsic tyrosine kinase activity. It is overexpressed in several malignant human tumors like breast cancer. A chimeric antibody by assembling a single-chain Fv antibody and a human IgG1 Fc fragment was constructed. This chimeric antibody reacts with tumor surface antigen p185c-erbB-2 specifically. In order to put the antibody into clinical application, two steps purification method was used to attain the antibody’s purity more than 95%. Both the lyophilized pharmaceutical formulations of the antibody were found. The formulations can keep the stability and activity of the antibody for at least one year. These results were the foundation of the chimeric antibody for cancer therapy.

Long non-coding RNA ( LncRNA) is a class of transcript (>200 nucleotides) that do not encode proteins. It plays an important role in epigenetic regulation and gene expression at transcriptional or post transcriptional level. The abnormal expression of LncRNA may lead to various pathological processes. Diabetic retinopathy ( DR ) is a multifactorial disease. Recent studies have shown that many specific expressions of LncRNAs are closely related to the genesis of DR. In this review, we summarized the recent advances in the function of LncRNA, the regulatory mechanisms of LncRNA involved in the development of DR, and the related therapies.

Objective:To observe the curative effect of potassium magnesium aspartate in the auxiliary treatment of ventricular pre -mature beat.Methods:Totally 70 patients with ventricular premature beat were randomly divided into the observation group (36 ca-ses) and the control group (34 cases).The patients were treated with metoprolol , and the patients in the observation group was treated with potassium magnesium aspartate as the auxiliary therapy , and the patients in the control group were treated with potassium chloride sustained release tablets as the adjuvant treatment .After 3-week continuous treatment , the changes of serum potassium , serum creatine kinase, creatine kinase, lactate dehydrogenase and ECG were observed in the two groups .The therapeutic effects and adverse drug re-actions were compared between the two groups .Results: After the treatment , the levels of serum potassium , serum creatine kinase isoenzyme, creatine kinase and lactate dehydrogenase were significantly improved when compared with those before the treatment (P<0.05), and the improvement of the observation group were significantly better than that of the control group (P<0.05).After the treatment, the heart rate and PR interval in the two groups were significantly improved (P<0.05), and there was no significant differ-ences between the two groups (P>0.05).The total effective rate of the observation group was 91.67%, which was higher than that of the control group (82.35%, P<0.05).The incidence of adverse drug reactions in the observation group was significantly lower than that in the control group (P<0.05).Conclusion:Potassium magnesium aspartate in the adjuvant treatment of ventricular premature beat can significantly improve the levels of serum potassium and serum myocardial enzyme and heart rate and ECG of the patients , and the efficacy and the incidence of adverse drug reactions are better than those of potassium chloride sustained -release tablets in the adju-vant treatment .

BACKGROUND:Studies have shown that the main functions of mesenchymal stem cels include direct participation in wound healing, growth factor secretion, promoting angiogenesis, immune regulation and inflammation, anti-oxidative stress, which can be used to treat a variety of acute and chronic diseases. OBJECTIVE:To review advances in mesenchymal stem cels in the inflammatory immunomodulation. METHODS: A computer-based search of Wanfang, CNKI and PubMed databases was performed for articles concerning advances in mesenchymal stem cels in the inflammatory immunomodulation published from January 2005 to August 2015. The search terms were “stem cels, mesenchymal stem cels, immune regulation, inflammation, immune cels, inflammatory factors, treatment” in Chinese and English, respectively. Finaly, 40 articles were included in result analysis. RESULTS AND CONCLUSION:Because of their immunomodulation and muti-directional differentiation, mesenchymal stem cels garner increasing attentions. In addition, mesenchymal stem cels can be harvested from different tissues and have goodin vitroamplification capability, which have a broad prospect in the clinical use, including tissue repair and anti-inflammation. As the most promising cels used clinicaly, mesenchymal stem cels show their superiority in the treatment of many diseases, especialy in inflammations induced by immune modulation imbalance. We believe that mesenchymal stem cels wil play an important role in the future cel biotherapy.

It is very important to develop nasal sprays with higher bioavailability and better targeting capability by making further use of advanced technology and new methods according to its characteristics. Intensive research has been searched on nasal sprays quality control methods which have been developed in the last few years. This review discusses the critical quality attributes of nasal sprays and the research progress of the quality control methods. Clarifies the characters examine of the nasal spray (pH, osmolality, particle size distribution and viscosity), content and related substances, packaging materials compatibility studies, spray pattern and droplet distribution methods of quality control.
