Methods FDG‐PET and CT imaging were performed in 62 patients with type 2 diabetes mellitus (T2DM ) or impaired glucose tolerance (IGT ). Lipid and glycemic profiles and inflammatory markers were detected in all patients. These patients randomly received treatments with either pioglitazone or glimepiride for 16 weeks.Results After 16 weeks ,pioglitazone‐treated group versus glimepiride‐treated group showed a significantly decreased visceral fat area[(109.1 ± 45.0) vs(122.5 ± 52.0 )cm2 ] and a significantly decreased visceral fat metabolic activity[(0.47 ± 0.11)vs(0.55 ± 0.11)](P<0.05). Conclusion Our study indicates that pioglitazone decreases the visceral fat volume and its metabolic activity in patients with T 2DM or IGT.

BACKGROUND:Because of deficiency of nerves and blood vessels of articular cartilage, its nutrition is mainly derived from the synovial fluid or synovial vascular osmosis. Limited in their ability to repair itself, so how to repair articular cartilage damage better become medical problems to be solved. OBJECTIVE:To review to the literatures on the repair of cartilage damage method and al ogeneic cartilage in vitro preservation method in recent years, and to find the optimal preservation conditions and the culture medium composition that suitable for in vitro preservation of al ogeneic cartilage tissues, thus enhancing the effect of al ogenic cartilage in vitro preservation. METHODS:A computer-based online search was performed in the PubMed database and the CNKI database to search papers on the in vitro liquid preservation of al ogeneic cartilage graft published from January 1990 to February 2013. The key words were“osteochondral al ograft, tissue culture, chondrocyte survival rate, in vitro”in English and“articular cartilage;al ogeneic transplantation;liquid preservation”in Chinese. The articles published earlier and repetitive researches were excluded. RESULTS AND CONCLUSION:At present, there are two methods for the preservation of al ogenic osteochondral grafts. After cryopreservation, the survival rate of chondrocytes is decreased significantly which can affect the transplantation effect, therefore there is less clinical application. Liquid preservation method can enhance the survival rate of cells, maintain the organization activity, but the preservation time is short that cannot be widely used. Scholars have further improved the environment of liquid preservation and composition of liquid culture medium, extended the in vitro preservation time of cartilage tissue, and improved the effectiveness of cartilage tissue preservation.

Objective:To explore the values of electroencephalogram (EEG) combined with glial fibrillary acidic protein (GFAP) in the early diagnosis and prognosis evaluation of viral encephalitis (VE).Methods:A total of 63 patients with VE admitted to the Hangzhou Seventh People′s Hospital from January 2016 to December 2019 were selected as the observation group. In addition, 80 healthy people suspected of central nervous system disease in the same period were selected as the control group. The data of gender, age, body mass and body mass index (BMI) were recorded, the Niolet V32 digital EEG instrument of American Nigolli Company was used for EEG inspection, and the level of serum GFAP was detected by enzyme-linked immunosorbent assay (ELISA). The general data, abnormal EEG results and the level of serum GFAP of the control group and the observation group were compared. The diagnostic values of EEG and its combination with serum GFAP in VE were analyzed by four grid table; and the diagnostic value of serum GFAP for VE was evaluated by drawing receiver operating characteristic (ROC) curve.Results:There was no significant difference in sex, age, body mass and BMI between the two groups ( P>0.05). The results of EEG diagnosis for VE showed that 11 of 63 cases were missed and 10 of 80 cases in the control group were misdiagnosed, and the sensitivity, specificity and accuracy of EEG diagnosis for VE were 82.54%, 87.50% and 85.31%, respectively. Compared with that of the control group, the level of serum GFAP of the observation group was higher: (460.19 ± 126.53) ng/L vs. (217.36 ± 53.17) ng/L, t =15.525, P<0.05. ROC curve showed that area under curve (AUC) of serum GFAP for VE diagnosis was 0.907 and cutoff value was 238.37 ng/L. The sensitivity, specificity and accuracy of EEG combined with serum GFAP in diagnosing VE were 93.65%, 83.75% and 88.11%, respectively, and the sensitivity and accuracy of EEG combined with serum GFAP were higher than those of EEG and GFAP alone. The results of 12-month follow-up showed that 20 of 63 VE patients had sequel (poor prognosis group), 43 patients had good prognosis (good prognosis group), and the incidence of adverse prognosis was 31.75%(20/63). There were significant differences in EEG and GFAP between the good prognosis group and poor prognosis group ( P<0.05). Conclusions:The sensitivity and accuracy of EEG combined with serum GFAP in the diagnosis of VE are good, which may be used for the early diagnosis and prognosis evaluation of VE.

Objective To investigate the coagulation function,the related factors and prognosis of preterm infants with periventricular hemorrhage-intraventricular hemorrhage (PVH-IVH).Methods Eighty-one preterm infants with PVH-IVH and 81 infants with non-PVH-IVH as a control were enrolled in the study.The changes in activated thromboplastin time(PT),activated partial thromboplastin time (APTT),Fibrinogen and D-dimer were determined by enzyme-linked immunosorbent assay.Clinical factors which were related to PVH-IVH in infants were analyzed with statistical analysis and prognosis was assessed with neonatal behavioral neurological assessment (NBNA).Results The average of gestational age in PVH-IVH group was(30.9 ± 1.79)weeks,in control group were (31.36 ± 1.39)weeks,and there was significant difference between the 2 groups (F =6.52,P =0.012).There were significant differences in APTI,and D-dimer between PVH-IVH and non-PVH-IVH infants(all P ＜ 0.05).Multivariate Logistic regression analysis showed that the related factors included gestational age,neonatal respiratory distress syndrome(NRDS),hyperoxia,and mechanical ventilation(OR =3.98,1.72,2.99,5.65,all P ＜ 0.05).The NBNA scores of the 2 groups were also significantly different(t =9.16,P ＜ 0.05).Conclusions The occurrence of PVH-IVH is very complex resulted from gestational age,NRDS,hyperoxia,mechanical ventilation and other factors.In order to avoid the occurrence of intracranial hemorrhage and improve the life quality of preterm infants,the NRDS was prevented as far as possible,coagulation abnormalities were managed positively and the mechanical ventilation was shortened.
