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.

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.

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.
