Objective To investigate the interaction between NMDA receptor subunit 2B (NR2B) and metabotropic glutamate receptor 5 (mGluR5) in the spinal cord of morphine-tolerant rats. Methods Sixteen male SD rats weighing 220-280 g were randomly divided into 2 groups with 8 rats in each group: control group (C) and morphine group (M). In group M morphine 10μg was administered intrathecally (IT) twice a day for 7 consecutive days. In group C equal volume of normal saline was given instead of morphine. Tail flick latency (TFL) (a segment of tail 4-5 cm long was immersed in 52-53℃ hot water) was used to measure the antinocicepitve effect of morphine before and 30 min after morphine administration every morning. MPE (percentage of maximal possible effect) was calculated (pain threshold after drug administration - baseline pain threshold)/(10- baseline pain threshold)× 100% . The animals were killed at the next day after last IT administration and the dorsal half of L4-5 spinal cord was isolated and homogenized for determination of NR2B and mGluR5 protein expression by Western blot and CO-IP. Results MPE was significantly increased at 1-5 d of drug administration and returned to baseline at 7 d in group M as compared with group C. The mGluR5 protein expression was significantly up-regulated in group M as compared with group C but there was no significant difference in NR2B protein expression between the 2 groups. Conclusion There is interaction between NK2B and mGluR5 in the spinal cord of morphine-tolerant rats.

The Tongmai Yangxin pill (TMYX) has potential clinical effects on no-reflow (NR); however, the effective substances and mechanisms by which this occurs remain unclear. This study evaluates the cardioprotective effects and molecular mechanisms of TMYX against NR. We used a myocardial NR rat model (2 h after myocardial ischemia and 2 h after reperfusion) to confirm the effect and mechanism of action of TMYX in alleviating NR.

Objective To analyze the clinical and radiographic features of short stature combined with skeletal deformity in children,and to diagnose exactly and cure promptly in children.Methods One hundred and twenty children were collected,included 69 males and 51 females.All of the children were collected detail medical history including history of birth,feeding,growth and development and family history and taken both physical and X ray examination that bone age could be evaluate by Gruelich-Pyle method.The children were taken a laboratory examination including calcium,phosphours,alkaline phosphatase,chromosome karyotype,and so on.Results Among 120 children,there were 36 cases(30.0%) of achondroplasia,20 cases(17.0%)of Turner syndrome,10 cases(8.0%)of multiple epiphyseal dysplasia,1 case(0.8%)of spondyloepiphseal dysplasia congenital,7 cases(5.8%) of spondyloepiphyseal dysplasia tarda,2 cases(1.6%) of osteogenesis imperfecta,1 case(0.8%) of cleidocranial dysplasia,5 cases(4.2%)of mucopolysaccharide Ⅳ,5 cases(4.2%) of pseudoachondroplasia,9 cases(7.5%)of hypophosphatemic ricket,24 cases(20%)of short limb dwarf.Among 120 cases,27 were regularity dwarfism(22.5%),93 cases were irregularity dwarfism(77.5%);Among 93 cases of irregularity dwarfism,80 cases were short limb dwarfism including 36 cases of short upper limb(short upper arm 35 cases,shortforearm 1 case),20 cases of short lower limb,24 cases of proportional short stature,13 cases of short trunk.X ray bone age lag 46 cases,ahead of schedule 15 cases(12.5%),normal 59 cases.Conclusions The main causes of short stature combined with skeletal deformity are genetic bone disease.To analyze the feature of clinical and radiographic is a valuble instrument for the children diagnosis of short stature combined with skeletal deformity.Part of them skeletal age were lagged.

OBJECTIVETo Understand the characteristics of the common complications in the gastric malignant tumor inpatients in our country, the related traditional Chinese and western medicine combined usage.
METHODBy using the method of frequency analysis and correlation, analysis the diagnostic and Prescribing information in HIS database of 20 national first-class ternary general hospital inpatients.
RESULTThe most common coexistent disease are malignant tumor in other parts, benign tumor. The most common complications are serous cavity effusion, lung infection, abnormal liver function. In other parts malignant tumor, more than 50% with advanced gastric malignancy; in other parts benign tumor, 86.00% located in the digestive and Urinary system, in the complications, digestive system diseases accounted for 23.80%; further according to the association rules of data mining, and calculate the combination scheme of the most commonly used for acid suppression drugs in combination with the centralizer and eliminate pathogenic traditional Chinese medicine (TCM).
CONCLUSIONIn the real world, most of the gastric malignant tumor disorder crowd is in the advanced stage, with lymph nodes and other parts of the transfer; and at the same time to incorporate the spleen and kidney disease in TCM zang-fu organs dialectical, should notice the reach mark early intervention, achieve the purpose of cure not ill; acid suppression hemostatic drugs combined the centralizer and eliminate pathogenic the three medicine combined treatment of Chinese traditional medicine is relevant.

Alzheimer's disease (AD) is the most common cause of cognitive impairment in older people. With the aging of society is more and more serious, AD caused great burden to patients and society. A β is a classical biomarker of AD, which has been widely used in clinical diagnosis of AD patients. Compared with positron emission tomography (PET) and single photon emission computed tomography (SPECT), near infrared fluorescence imaging has many advantages including highly sensitive, non-invasive, safety and inexpensive. Therefore, many research groups have focused on developing the molecular probes of near-infrared fluorescence (NIRF) imaging. In this article, we will review the progress of the probes of NIRF.
