Objective To investigate the specific expression of endoplasmic reticulum stress-related GRP78 and CHOP in podocyte of MKR mice with diabetic nephropathy (DN);To discuss the intervention effect of Zuogui Jiangtang Yishen Decoction (ZGJTYS). Methods 8-week old MKR mice were randomly divided into five groups:blank group, model group, ZGJTYS group, 4-Phenylbutyric acid group, gliquidone+benazepril group, and normal control group consisting of wild type C57BC/6 mice, 10 mice per group. All mice from model group and each treatment group received high-fat diet feed and unilateral nephrectomy to make the DN model. Mice from treatment groups received medicine intervention for four weeks. The levels of FBG were detected by electrochemical detection method, and the UmAlb was detected by ELISA. The expressions of GRP78, CHOP mRNA, and protein were detected by RT-PCR and Western blot. The morphological structure changes of the podocytes were observed by transmission electron microscopes. Results Compared with blank group, FBG and UmAlb in the model group increased significantly (P<0.01);the expressions of GRP78 mRNA and protein markedly decreased (P<0.01);the expressions of CHOP mRNA and protein increased (P<0.01). Compared with the model group, FBG and UmAlb in each treatment group significantly decreased (P<0.01);the expressions of GRP78 mRNA and protein in the ZGJTYS group and 4-Phenylbutyric acid group increased (P<0.01), the expressions of CHOP mRNA and protein decreased (P<0.01). The renal pathological lesions of each treatment group were significantly improved compared with model group. Conclusion ZGJTYS Decoction can effectively improve the damaged podocyte induced by endoplasmic reticulum stress, delay DN progress.

Objective To investigate the therapeutic effect of Pingyangmycin combined with Triamcinolone Acetonide on the huge faciocervical lymphatic malformations (LMs) in infants.Methods Sixty-seven infants with LMs located in head and neck from January 2009 to June 2014 were retrospectively analyzed in Kunming Children's Hospital.Thirty-five males and 32 females were enrolled,aged from 1 month to 4 years,with a median age of 1.3 years.Computed tomography and ultrasonography were used to evaluate the location,size and extent of LMs before treatment in all the patients.The size of lesion varied from 5.2 cm ×7.5 cm to 9.2 cm × 10.5 cm.All patients were given local injection of Pingyangmycin combined with Triamcinolone Acetonide after puncturing fluid with uhrasonography guiding under general anesthesia.The injection was repeated every 30 d when necessary.Results The number of injections varied from 2 to 5 times,with a median number of 3.9 times.All cases were followed up for 5 to 36 months.Thirty-two cases (62.68％) were cured,improvement in 19 cases (28.36％) and no effect in 6 cases (8.96％).The total effective rate was 91.04％.There was no severe allergic reaction or pulmonary fibrosis.Secondary operation was performed after 6 months in 12 cases.Two post-operative complications were found,1 was minor paralyses of mandibular branch of facial nerve,with mouth askew,the other was trachyphonia,who were both improved after rehabilitation treatment.Conclusions In order to avoid serious complications,the huge LMs may be given local injection of Pingyangmycin combined with Triamcinolone Acetonide after puncturing fluid with ultrasonography guiding.Graded sclerotherapy provides for a less invasive and shorter course of treatment.The complications and risk of secondary resection increase slightly if sclerotherapy has no curative effect.

Objective To investigate the alterations of regional spontaneous activity in patients with classical trigeminal neuralgia (CTN) during resting state.Methods Twenty-seven patients with CTN (CTN group) and 27 healthy subjects (control group) were recruited and underwent a rest-state functional MRI.The regional homogeneity (ReHo) analysis was used to compare the differences of regional synchronization of spontaneous brain activity.And correlation tests were performed between ReHo values in the abnormal brain areas and clinical metrics (visual analogue scale and disease duration) of the disease.Results Compared with control group (P＜0.05,Gaussian random field correction),ReHo increased in bilateral primary somatosensory cortex (S1) and primary motor cortex (M1),right supplementary motor area (SMA),inferotemporal cortex and cerebellum,left thalamus,limbic lobe,parahippocampa gyrus,middle and superior temporal gyrus in CTN group;ReHo decreased in bilateral insula,prefrontal cortex and orbitofrontal cortex,right frontal medial cortex and superior temporal gyrus,left anterior cingulate area,supramarginal gyrus and cerebellum in CTN group.ReHo values in right frontal medial cortex was negatively correlated with the course of disease (r=-0.45,P=0.03).The ReHo values of left primary sensorimotor cortex were positively correlated with the visual analogue scale scores (r=0.46,P=0.02).Conclusion CTN patients has abnormal functional homogeneity of spontaneous brain activity in regions involved in the pain processing,which can help understanding mechanism of CTN.

Objective To explore the developmental characteristics of different functional levels of autism and the diffe-rence in children. Methods A total of 159 autistic children aged 13-71 months including 85 high-functioning autistic (HFA) chil-dren and 74 low-functioning autistic (LFA) children were evaluated for their developmental characteristics by the development scales from the psycho-educational profile-revised (PEP-R). Results Within the same age group, both HFA and LFA children had obvious unbalance in individual ability development (H=41.68~113.51, P<0.01). Impaired cognitive performance is most common in HFA children. The development of cognitive performance was inconsistent with cognitive expression while the gross motor development was normal. The ability development in LFA children were all impaired, especially in imitation, cogni-tive performance and cognitive expression. With increasing age, the scores of imitation, perception, cognitive performance, cog-nitive expression and overall development quotient were increased gradually in HFA children (P<0.05) while the scores of cogni-tive performance and overall development quotient were decreased in LFA children. Conclusions Autistic children tend to have abnormal developmental progress and order, and individual ability development varies by functional level in autistic children with increasing age.
