To study the level of macrophage migration inhibitory factor (MIF) in serum and the expression of MIF mRNA in abdominal subcutaneous adipose tissue,and to investigate its impact on insulin resistance and islet β-cell dysfunction in gestational diabetes mellitus (GDM).120 pregnancy women from the Affiliated Hospital of Qingdao University Medical College and Taian Central Hospital were enrolled,including 60 GDM women and 60 women with normal glucose tolerance (NGT).The serum MIF in GDM group was higher than that of NGT group [(3.58±1.02 vs 1.23±0.62) ng/ml,P<0.01].Multiple stepwise regression analysis showed that body mass index was an independent affective factor of the serum levels of MIF (r2 =0.516).The serum levels of MIF and the expressions of MIF mRNA in abdominal subcutaneous adipose tissue were significantly higher in GDM group than NGT group.MIF may contribute to insulin resistance and β-cell dysfunction in GDM.Body mass index seems to be an independent factor in affecting the serum levels of MIF.

AIM: To explore the way and the feasible time of olfactory ensheathing cells (OECs) transplanting to experimental autoimmune encephalomyelitis (EAE) rats, and to investigate the migration of OECs after transplanted to EAE and the possible mechanism of inducing the protective effect. METHODS: The Lewis rats, which were divided into MOG group and GPSCH group according to the induction by MOG~Igd and GPSCH separately, were used to made EAE model. The animals in MOG group were divided into 3 subsets: OECs blank group (MOG0 group, 4 rats );OECs transplantation by vena caudalis (MOG1 group, 7 rats);OECs transplantation by lateral cerebral ventricle (MOG2 group, 4 rats). The animals in GPSCH group were also divided into 2 subsets: OECs blank group (GPSCH0 group, 4 rats);OECs transplanted by vena caudalis (GPSCH1 group, 4 rats). OECs transplanted through different ways in peak incidence, then the rats were measured to determine whether the symptom was ameliorated. Two weeks after transplantion, the rats were killed and the methods of histofluorescence and histopathology (HE staining and Luxol fast blue staining) were used to examine the distribution of the labeled OECs in EAE rats' bodies and to explore whether there was some amelioration in histology. RESULTS: After OECs transplantation by vena caudalis or lateral cerebral ventricle, the rats' symptom improved. Compared to OECs blank groups, there was significant difference in clinical scores (F=18.470, P<0.01;t=-7.147, P<0.01). No significant difference between MOG1 group and MOG2 group was observed (P>0.05). The labeled OECs entered into the brain through the broken blood-brain-barrier after transplantation by vena caud-alis, the labeled OECs near the subpial area and around the lesions were found. OECs transplantation by the way of lateral cerebral ventricle showed great migration potential, the cells moved towards to the lesions extensively. No significant difference between OECs transplantation group and OECs blank group in histopathology (HE staining and LFB staining) was observed (P>0.05), and the same thing also happened between MOG1 group and MOG2 group (P>0.05). CONCLUSION: The transplantation of adult rats' OECs improves the EAE rats' symptom at some degree by the ways of vena caudalis or lateral cerebral ventricle.

BACKGROUND:Currently, there are few reports on the effects of Caspase inhibitors combined with Cocktail protease inhibitors on isolation and purification of islet cel s. OBJECTIVE:To explore the effects of Caspase inhibitors and Cocktail protease as protectors on islet cel s during isolation and purification process. METHODS:New-born pigs were selected to separate, purify and culture the islet cel s, and after 24 hours of culture, the specimens were divided into three groups:blank control group, experimental group A (Caspase inhibitors and Cocktail protease were added only during digestion process), and experimental group B (Caspase inhibitors and Cocktail protease were added both during digestion and culture processes). AO-EB staining was used to qualitatively observe cel morphology and apoptosis. Flow cytometry was employed to quantitatively detect cel viability and apoptosis. RESULTS AND CONCLUSION:Percentages ofβcel s were 66.91%in blank control group, 84.58%in the experimental group A, and 87.15%in the experimental group B. The proportions of living cel s, apoptotic cel s and dead cel s were 56.52%, 16.15%, 21.25%in the blank control group, 62.27%, 14.66%, 14.47%in the experimental group A, and 73.09%, 6.83%, 10.28%in the experimental group B, respectively. These findings indicate that in the process of digestion and culture in vitro, Caspase inhibitors and Cocktail protease inhibitors can both obviously decrease the loss of cel s, and increase the percentage of islet beta cel s.

BRICS has been dealing with the problem of increase in the number of the patients who require an-tiretroviral therapy and this therapy’s price-rise by promoting medicine to domestic production and reducing the impor-ted drug price. This paper reviewed the situation of BRICS HIV epidemic and prevention, anti-retroviral therapy drugs production and supply, drug security policy and strategy, and the following seven recommendations are straight forwarded to China based on the BRICS AIDS antiretroviral treatment coverage strategic comparison:(1) The estab-lishment of an ARV drugs co-ordination mechanism;(2) The reduction of the drug patent licenses while increasing the domestic generic drugs possibility;(3)Negotiations with the original research process of domestic pharmaceutical enterprises to obtain a voluntary license or speed up the technology transfer;(4) The use of antitrust laws to promote access to medicines for a voluntary license pharmacy localization; ( 5 ) If necessary, starting the compulsory medi-cines licensing to achieve localization;(6) Reducing the drug prices by bargain and negotiation;and (7) Strengthe-ning NGO built-in capacity.

Objective To investigate clinical effects of early postoperative oral enteral nutrition on immune function for colorectal cancer patients,to provide a reference for clinical treatment.Methods We selected 90 colorec-tal cancer surgery patients from January 2012 to April 2015,and they were divided into two groups by random number method.50 cases in the study group were given early oral enteral nutrition,and 40 patients in the control group were given postoperative parenteral nutrition.Before and after treatment,the quality of life,complications,immunology indi-cators,nutrition indicators were compared in two groups.Results In the observation group,the postoperative fever, exhaust time,hospital stay,hospital costs,quality of life scores were (54.29 ±5.76)h,(57.89 ±5.95)h,(10.48 ± 1.63)d,(41 432.85 ±2 165.46)RMB,(79.23 ±5.17)points,which were significantly lower than those in the con-trol group,the differences were statistically significant (t =8.69,P =0.00;t =8.61,P =0.00;t =9.49,P =0.00;t =5.54,P =0.00;t =4.16,P =0.01);7d after the treatment,the IgA,IgG,IgM,CD +4 ,CD +4 /CD +8 in observation group were (1.92 ±0.49)g/L,(11.31 ±2.24)g/L,(0.99 ±0.21)g/L,(41.21 ±5.51)%,(1.72 ±0.32),which were better than those in the control group,the differences were statistically significant (t =2.05,P =0.04;t =2.11, P =0.04;t =2.12,P =0.04;t =3.64,P =0.01;t =2.23,P =0.03).In observation group,postoperative 7d Hb, TRF,ALB,PAB were (113.28 ±13.36)g/L,(3.02 ±0.39)mg/L,(38.97 ±3.15)g/L,(333.15 ±18.35)mg/L, which were better than those in the control group,the differences were statistically significant (t =3.45,P =0.01;t =2.18,P =0.03;t =2.32,P =0.04;t =3.21,P =0.01).7d after operation,the CRP level of observation group was(7.29 ±2.05)mg/L,which was significantly lower than that of the control group,the difference was statistically sig-nificant (t =4.22,P =0.01 ).The incidence rate of postoperative complications in the observation group was 26.00%,that of the control group was 40.00%,the difference was statistically significant (χ2 =4.52,P =0.01). Conclusion Early oral enteral nutrition in patients with colorectal cancer will help to improve immune function, nutritional support,reduce the inflammatory response,which will help postoperative recovery.

Objective To analyze the clinical and imaging characteristics of congenital sensorineural hearing loss (CSNHL)children combined with white matter (WM)lesions in order to provide evidence for clinical practice. Methods With referral to the Department of Pediatrics,Peking University First Hospital from November 201 1 to De-cember 201 5,documents of 78 patients of CSNHL combined with WMlesions were collected and analyzed for the clini-cal and imaging characteristics.Results Bilateral severe -profound hearing loss existed in all 78 cases,48.1 %(25 /52 cases)of the patients exhibited gross motor development delay,98.1 %(51 /52 cases)of them had normal cognition development.One hundred percent (61 /61 cases)of patients had abnormal language development.Infection occurring during pregnancy existed in 21 .2%(1 1 /52 cases)of the patients,the premature and smaller for the gestational age in-fants accounted for 28.9% (1 5 /52 cases).The bilateral multiple WMlesions from the brain MRI were in dot to flake sizes with sharp boundary,the intensity of T1 -weighted imaging decreased,T2 -weighted imaging and fluid attenuated inversion recovery increased.Eighty -two point one percent (64 /78 cases)of the patients were found to have the periventricular and subcortical WM involvement.The most frequently affected periventricular region was the posterior horn (91 .9%,68 /74 cases),followed by the anterior horn and temporal horn,and the least with the body involvement. The former three had a combined lesion tendency (55.4% -68.9%).There was an extensive involvement in the sub-cortical WMof parietal,frontal,temporal and occipital lobes respectively(73.5% -88.2%).Subcortical WM involve-ment of multiple lobes was common (accounted for 67.6% -77.9%).The enlargement of bilateral ventricles existed in 37.2%(29 /78 cases)of the patients and cystic changes in the subcortical WM of anterior temporal lobe could be found in 9.0% (7 /78 cases)patients.Calcification in 2 CT cases was reported.Corpus callosum and basal ganglia of all cases were normal.For cases with MRI scans more than once,WMlesions of 96.0%(24 /25 cases)patients became silent or self -restored.Conclusions The clinical presentations of CSNHL combined with WM lesions are mild,not paralleled with their multiple foci.It is considered as demyelination or a delay of myelination.Due to its benign course, it is probably not the contraindication for the cochlear implantation.

Objective To analyze the clinical characteristics of 3 unrelated boys with paroxysmal nonkinesigenic dyskinesia and developmental delay caused by de novo mutation in KCNMA1,and to expand the knowledge of clinical phenotype of KCNMA1 mutation.Methods Clinical data of patients were collected,including gender,age,condition of the perinatal period,personal history,and family history.And the features of genotype data were collected including features of attack,developmental milestones,physical examinations,treatments,and responses to treatment.The data including blood biochemical results,results of metabolic screening and genetic testing and the pedigree validation were collected,while the relationship between phenotype and genotype was analyzed.Results (1)Phenotypic features:3 unrelated boys were diagnosed.The ages of disease onset were 20 days,7 months and 13 months,respectively.All the patients manifested paroxysmal nonkinesigenic dyskinesia and were characterized by the episodes that occurred during wakefulness,presented with sudden onset of asymmetric limb dystonic posture,sometimes with nystagmus and strabismus,or sudden decrease of voluntary movement of limbs with hypotonia and occasional esotropia and yawning.There was no loss of awareness during attack.No precipitating factors were observed before attacks.The developmental milestones were delayed.Three children had no response to anti-epilepsy drug before diagnosis.After diagnosis,2 cases used Clonazepam and 1 case showed less attack.There was not any epileptic seizure until the last follow-up at the ages of 3 years and 6 months old,7 years old,and 5 years and 8 months old,respectively.The frequency of attacks was decreased.The episodes were recorded during video-electroencephalogram(EEG) monitoring,which showed normal ictal and interictal EEG.(2)Genotypic features:all 3 children were detected to have KCNMA1 genetic heterozygous missense mutation,while c.2650G>A (p.Glu884Lys) mutation was identified in 1 patient,and c.3158A>G(p.Asn1053Ser)mutation in the other 2 patients,but no such mutation was found in their parents.Conclusion This finding expands the phenotype of KCNMA1mutation.KCNMA1 should be considered as one of the candidate genes for screening in patients with early onset of paroxysmal nonkinesigenic dyskinesia without triggers,or early-onset of developmental delay,with or without epilepsy.

The response of glueagon to the change of glucose and its relation to blood pressure in 71 eidely patients with type 2 diabetes was investigated. The results showed that the postprandial increment of glucagon in the group of patients with postprandial 2h plasma glucose increment<2.5 mmol/L was significantly higher than that in the group with plasma glucose inerement≥ 2.5 mmoi/L (P<0. 05). The postprandial increment of glucagon in patients with normal blood pressure was significantly higher than that in patients with hypertension (P<0.05). The results suggest that the decreased response of glucagon to the change in plasma glucose in elderly patients with type 2 diabetes is related to increased blood glucose and high blood pressure.
