RESULTS:ln all cases, conjunctiva healing, completely cover the sclera and conjunctiva socket recover ideal depth after operation in 15 cases, 1 case was fail.
CONCLUSlON: Preserved amniotic membrane transplantation is an effective method to treat conjunctival dehiscence and keeping the ideal conjunctival socket depth after orbital implantation.

OBJECTIVETo investigate a manipulating therapy for treatment of anterior shoulder dislocation in elderly.

METHODSFrom October 2011 to June 2012,27 elderly patients with anterior shoulder dislocation were treated by extorsion traction and pushing manipulation with fingers, including 7 males and 20 females aged from 65 to 86 years old with an average of 77. The course of disease ranged from 1 h to 1 d. The shoulder manifested square deformity, Dugus signs showed positive, and X-ray displayed anterior shoulder dislocation. Dugus fixation was applied for and removed external fixation at 3 weeks after operation and carried out shoulder functional exercise. Functional evaluation standard on shoulder joint injuries was used for evaluate clinical outcomes.

RESULTSAll patients were gained reduction for the first time, and followed up at 3 months after operation, no dislocation occurred. According to functional evaluation standard on shoulder joint injuries, 22 cases got an excellent result,2 cases good,and 1 case moderate.

CONCLUSIONExtorsion traction and pushing manipulating therapy for treatment of anterior shoulder dislocation in elderly, which has advantages of simple, convenient, less painful, and can avoid iatrogenic injury, is feasible to widespread.

The colorimetric method has been well developed to detect the sensitivity of most antiproliferative drugs with the advantages of objectivity and accuracy. Many parameters including the dosage and the absorbance of crystalline violet, the extraction time of the solvent, plate effect and marginal effect were investigated, then the optimized method was applied further to measure the biological activity during the refolding of recombinant human IFN-? inclusion bodies.

The author analyzes the basic information in recent years,including overall students scale,students' age,application trends,etc.Some suggestions are made,regarding to recruiting plan,applicant qualification,recruiting mode,etc,in order to further improve the recruiting and graduate management.

Small molecule fluorescent probes have gained widespread attention for their advantages of high selectivity, sensitivity, and easy to operate, and have played a critical role in the detection of various species. They have also demonstrated great potential in the field of biomedical research. Iron, as the most abundant transition metal in the human body, plays a vital role in many physiological functions. Due to the influence of the reductive microenvironment of cell, ferrous ion (Fe²⁺) is the main component of labile iron in living cells. Heme, consisting of Fe²⁺ and protoporphyrin IX, is one of the main signaling molecules that wrap biological iron in the human body, and also participates in many physiological and pathological processes. Therefore, the development of small molecule fluorescent probes for detecting Fe²⁺ and heme as effective monitoring tools will help to further understand their pathological and physiological functions, with potential applications in other fields. This review summarizes the research progress of small molecule fluorescent probes for Fe²⁺ and heme detection in recent years, and provides insights into future directions for their development.

Abstract: Schistosomiasis is a serious major parasitic disease that threatens human life and health. A better understanding of the mechanism of host-schistosome interactions is the key to designing new prevention and control strategies. MicroRNAs (miRNAs) are endogenous small non-coding RNA molecules, which lead to the degradation of the target messenger RNA (mRNA) or inhibition of its translation in a sequence-specific manner. Both schistosome and its host produce miRNAs, which can be secreted by extracellular vesicles (EVs). There is accumulating evidence that miRNAs from schistosome can be taken up by host cells, and finely manipulate the phenotype of host cells for their survival or pathogenesis in a cross-species manner, even inhibiting the growth and metastases of hepatoma cells. It is still unknown whether host free miRNAs can be taken up by schistosome, but this phenomenon is highly probable. miRNA-mediated cross-species regulation has emerged as a novel mechanism for host-schistosome interactions, and this review summarizes the advances in this regard.

With the application of monoclonal antibody technology more and more widely, its production technology is becoming more and more perfect. Small molecule monoclonal antibody technology is becoming a hot research topic for people. The application of traditional Chinese medicine small molecule monoclonal antibody technology has been more and more widely, the technology for effective Chinese medicine component knockout provide strong technical support. The preparation of monoclonal antibodies and small molecule knockout technology are reviewed in this paper. The preparation of several steps, such as: in the process of preparation of antigen, hapten carrier coupling, coupling ratio determination and identification of artificial antigen and establishment of animal immunization and hybridoma cell lines of monoclonal antibody, the large-scale preparation; small molecule monoclonal antibody on Immune in affinity chromatography column method is discussed in detail. The author believes that this technology will make the traditional Chinese medicine research on a higher level, and improve the level of internationalization of Chinese medicine research.

Objective The objective of the present study was to evaluate the early auditory development in hearing impaired infants by LittlEARS? auditory questionnaire .Methods A total of 162 hearing impaired infants participated in the study .LEAQ consists of 35 items ,which were further divided into receptive auditory behavior , semantic auditory behavior ,and productive auditory behavior .The assessment was performed before hearing aid fit‐ting ,3 ,6 and 12 months after hearing aid fitting ,respectively .Results LEAQ scores improved dramatically in the first 12 months after hearing aid fitting ,total LEAQ scores prior to hearing aid fitting ,3 ,6 and 12 months after hearing aid fitting were 10 .47 ,17 .73 ,20 .64 and 26 .47 ,respectively .The receptive auditory behavior performance improved significantly after 3 months of hearing aid use .The duration of hearing aid use for dramatic improvement of semantic auditory behaviors ,and productive auditory behavior was 6 and 12 months ,respectively .The age of hearing aid fitting ,living environments ,degrees of parent education and degrees of hearing loss influenced LEAQscores significantly .Conclusion Hearing impaired infants exhibited significant auditory improvement in the first 12 months after hearing aids fitting .Early hearing aid fitting ,high level of parent education and well living environ‐ments promote preverbal auditory development .LEAQ is an effective tool for clinical auditory assessment and moni‐toring in infants and little toddlers .

Objective To investigate the immunoregulatory effects of propofol on airway hyperresponsiveness,airway inflammation and Thl/Th2 ratio in the asthmatic mice.Methods One hundred female BALB/c mice,aged 6-8 weeks,weighing 18-20 g,were randomly divided into 5 groups (n =20,each):control group (normal saline i.p.,group C),asthma group (group A),low-dose propofol (50 mg/kg i.p.,group LP),medium-dose propofol (100 mg/kg i.p.,group MP) and high-dose propofol (150 mg/kg i.p.,group HP).Mice of groups A,LP,MP and HP were sensitized with ovalbumin (OVA),mice of group C were sensitized with normal saline.24 h after the last challenge,animals were sacrificed by lethal dose of pentobarbital sodium.Blood and bronchoalveolar lavage fluid (BALF) were collected for determination of serum OVA-specific IgE and the levels of cytokines (IL-4,IL-5 and IFN-γ) in the BALF.Airway responsiveness was measured by the forced-oscillation technique and histological inflammation scores were measured by staining with hematoxylin and eosin.Results Propofol (group LP and group MP) attenuated airway hyperresposiveness to the muscarinic agonist methacholine in OVA-induced asthma.Different doses of propofol (group LP,group MP and group HP) decreased eosinoplils influx in lungs.In addition,propofol treatment reduced expression of IL-4,IL-5 and serum OVA-specific IgE and increased the ratio of IFN-γ/IL-4.Conclusion The study demonstrates a potential protective value of propofol in alleviating airway inflammation,up-regulating Th1/Th2 ratio and attenuating airway hyperresposiveness in the asthmatic mice.
