G protein-coupled receptor 119 (GPR119) has been a promising target for the treatment of type 2 diabetes. It can not only directly promote insulin secretion, but also indirectly increase insulin secretion by stimulating the release of glucose-dependent GIP/CLP-1 without causing hypoglycemia. The remarkable advantages of small molecule GPR119 agonists make it one of the research hotspots for the development of type 2 diabetes drugs. This article reviews the anti-diabetic small molecules based on the GPR119 target in the past five years.

Objective To improve the awareness of the CT and/or MRI appearances and clinical presentations of Kasabach-Merritt syndrome(KMS),6 cases were reported.Methods The CT and/or MRI and clinical characters of 6 cases of KMS were reviewed and analyzed.Results Thrombocytopenia,and consumption coagulopathy were presented in all 6 cases.The paravertebral mass of posterior mediastinum, right pericardial lesion,skin and soft tissue of left arm were shown as iso-,hypointensity on T1-weighted image,iso-,hyper-intensity on T_2-weighted image,and with heterogeneous enhancement after contrast administration in three cases.Splenomegaly was presented in one case,it showed homogenous hypoattenuation on unenhanced CT,and diffused heterogeneous enhancement after contrast administration. On MRI,spleen was shown as hypointensity on T_1-weighted image,hyperintensity on T_2-weighted image, and with heterogeneous enhancement after contrast administration.There were lesions in both bones and spleen in one case.Osteopenia and thinned cortex were shown on the metaphyses of upper and lower extremities.Spleen enlarged and showed multifocal hypoattenuation lesions,the peripheral region enhanced on the early phase,and some of the lesions filled on the delayed phase after the contrast administration.One case showed huge hypoattenuation lesion in the left lobe of liver with gradually filling of the mass after peripheral enhancement.Conclusion Thrombocytopenia and consumption coagulopathy suggest the entity of extensive hemangioma.Splenomegaly with diffuse or focal hypoattenation or hypointensity in MRI infers the diagnosis of hemangioma.

Objective To investigate the effect of excessive fluoride,aluminum on Zn,Fe,Ca,Mg,Cuin rat blood.Methods Forty eight SD rats were randomly divided into 4 groups matched with their weights:control group,high aluminum group,high fluorine group and high fluorine-aluminum group.Aluminum content in their drinking water was 0,90,0,90 mg/L respectively.Fluorine content of their feed was 5.2,5.2,106.0,106.0 mg/kg and aluminum Was 6.8,6.8,19.7,19.7 mg/kg respectively.90 days later,the level of blood Zn,Fe,Ca,Mg, Cu Was detected by the atomic absorption spectrometry.Results Compared among these groups,Zn,Fe,Mg and Cu content of the whole blood had significant difierences(F=46.25,14.74,6.10,2.93,P<0.05),while Ca content of the whole blood did not significantly change(F=2.81.P>0.05).Factorial analysis showed that excessive intake of aluminum could significantly decreased Zn,Fe,Mg content of the blood(F=42.66,5.41,7.04,P<0.05)and excessive intake of fluorine could significantly decreased Zn,Fe,Mg,Cu content of the blood(F=64.50,37.90,9.75,6.74, P<0.05).The coexistence offluorine and Muminum had interaction to the level of Zn(F=31.59,P<0.05)and did not obviously interact with other elements(F=0.91,1.63,1.51.0.00,P>0.05).Compared with the control group [(131.30 ±13.86)μmol/L,(10.24 ±1.02),(1.71 ±0.19)mmol/L,(20.43 ±4.42)μmol/L],Zn content in the high aluminum group[(90.84±9.98)μmol/L]decreased significantly(P<0.05),so did Zn,Fe,Mg content in tlle high fluorine group[(85.85 ±10.92)μmol/L,(8.49 ±0.68),(1.52 ±0.13)mmol/L],the difference being statistically significant(P<0.05)0Zn,Fe,Mg,Cu content in the high fluorine-aluminum group,being(82.82 ±11.00)μmol/L, (8.16±0.45),(1.46±0.09)mmoL/L,(15.69±2.38)μmol/L,respectively,all decreased signitlcarIdy(P<0.05). Compared with the high aluminum group[(9.43±1.09)mmol/L],Fe content of the high fluorine aluminum group[(8.16±0.45)mmol/L]decreased significantly(P<0.05).Conclusions Excessive fluoride can cause blood zn, Fe,Mg,Cu decline,so can excessive aluminum.Combination of excessive fluofine and aiuminum has 8ignificant synergic effect on the level of Zn but have rio influence on Ca.

Objective To explore the effects of virtual reality (VR) combined with motor imagery therapy on the upper limb function of hemiplegic stroke survivors.Methods Thirty-nine hemiplegic stroke patients were divided randomly into a treatment group (n =20) and a control group (n =19).Both groups were treated with motor imagery therapy,but the treatment group also received VR training lasting 20 min/day,6 days/week for 8 weeks.All of the patients were assessed with the Fugl-Meyer (FMA) upper limb assessment,the modified Barthel index (MBI) and electromyography at the beginning and after eight weeks of treatment.Results Before the intervention there was no significant difference between the groups in any of the assessments.After eight weeks of treatment,all the assessment results in the treatment group were significantly better than those in the control group.Conclusion Virtual reality combined with motor imagery therapy can distinctly improve the upper limb motor function of hemiplegic stroke survivors and their ability in the activities of daily living.

OBJECTIVETo evaluate the curative effect of Danxiaoling Pill (DXLP), a Chinese herbal preparation, in treating intrahepatic cholestasis in pregnancy (ICP).

METHODSFifty-eight cases of ICP were divided randomly into two groups and treated by DXLP and Composite Yiganling as control respectively with the other identical conventional treatment. The changes of clinical symptoms, related laboratory parameters after treatment and the condition of labor were observed.

RESULTSThe total effective rate in both groups was 100%, but the markedly effective rate in the DXLP treated group was higher than that in control group (P < 0.01). Levels of blood cholyglycine acid (CGA), alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin, total cholesterol and low density lipoprotein were all decreased in both groups after treatment, but DXL showed a better efficacy in decreasing CGA, ALT and AST than that of Yiganling. Moreover, the amniotic fluid meconium contaminated rate, premature delivery occurrence in the DXLP group were lower than those in the control group, while the weight of newborn baby was higher in the former than in the latter.

CONCLUSIONDXLP could effectively lower the serum bile acid and improve liver function in treating ICP.

The contamination of extrinsic harmful contaminants including mycotoxins, heavy metals and pesticides, etc, brings serious risks to traditional Chinese medicines (TCMs), further to human health. Due to their unique photoluminescence, chemiluminescence, electrochemical and electrochemiluminescence properties, semiconductor quantum dots (QDs) nanoparticles are widely used to immobilize bioprobes and biosensors, etc. In this review, the luminescence characteristics and specific ligands of QDs probles which are used to determine contaminants were summed up. Then, the applications of QDs-coated novel probes in the determination of mycotoxins, heavy metals and pesticides were discussed in detail. In addition, the contamination levels and characteristics of extrinsic harmful residues in TCMs were investigated. Further, the maximum levels of those contaminants in TCMs were compared with those set by various countries. Finally, the future development trends and problems of QDs-coated probes in the determination of those extrinsic residues in TCMs were prospected.
