Diabetes is a common clinical disease, with glucose and lipid metabolism disorder as the main clinical manifestation. The spleen of middle jiao can transport and transform the essence of grain and water. It is also the source of qi and blood, which also provides material foundation for the glucose and lipid metabolism. The spleen deficiency and dampness stasis can lead to the phlegm and blood stagnation, which are closely related to high sugar, high fat, high blood coagulation and vascular endothelial damage. This article discussed the relationship between the changes of spleen function of middle jiao and glucose and lipid metabolism, and provided some theoretical methods for clinical prevention and treatment of diabetes.

OBJECTIVETo investigate the effect of noise on the antioxidant capacity in different regions of brain tissue in guinea pigs.
METHODSThirty male white red-eye guinea pigs were equally and randomly divided into five groups: 1-, 3-, 7-, and 14-day groups after noise exposure and control group. The guinea pigs of the experimental groups were exposed to steady white noise with a sound pressure level at 100 dB for 8 h per day and for 2 consecutive days. The auditory brainstem response (ABR) of guinea pigs, as well as the glutathione (GSH) level, methane dicarboxylic aldehyde (MDA) level, and superoxide dismutase (SOD) activity in the cerebrum, cerebellum, and hippocampus, was determined prior to and 1, 3, 7, and 14 days after noise exposure.
RESULTSAfter noise exposure, the shifts in ABR threshold of the experimental groups were significantly higher than that of the control group (P<0.05). Compared with those in the control group, the SOD activity and GSH level both significantly decreased in the cerebrum tissue of each experimental group after noise exposure (P<0.05) and MDA content significantly increased in the 1-day group (P<0.05). As for cerebellum tissue, the SOD activity and GSH level in the 7-day group were significantly lower than those in the control group (P<0.05), but there was no difference in MDA level between each experimental group and the control group (P>0.05). In comparison with those in the control group, the GSH and MDA levels in the 1-day group after noise exposure were significantly higher, and the GSH and MDA levels in the 3-day group and the MDA level in the 7-day group after noise exposure were significantly lower (all P<0.05).
CONCLUSIONNoise exposure can lead to hearing loss and affect the antioxidant capacity of brain tissue, which indicates that the improvement in antioxidant levels may alleviate noise-induced damage.

Background and purpose:Cervical cancer is one of the most common cancer in Xinjiang, especially for Uygur from southern Xinjiang and its pathogenesis is not clear. MicroRNA (miRNA) is a class of small non-coding RNA playing an important regulatory role. Its expression and dysfunction is closely related to the development of tumors. In this study, we screen and preliminary analyse expression of miRNA in cervical squamous cell carcinoma samples with human papillomavirus (HPV) 16 positive of Uygur patients. The target genes of miRNA were predicted.Methods:miRNAs were pre-screened by using miRNA microarray technology in 5 cases of HPV16 positivity Uygur patients from southern Xinjiang with cervical squamous cell carcinoma. Fifteen cases specimens were examined by qRT-PCR for preliminary veriifcation, and 83 cases of cervical cancer were detected and analysed the expression of miRNA; Targeted genes were predicted by using four softwares of target scan, miRwalk, miRanda and Pictar.Results:Eighteen differentially expressed miRNAs were selected by SAM software in 5 cases of HPV16 positivity southern Xinjiang Uygur cases with cervical squamous cell carcinoma.miRNA-138 and miRNA-720 were found expressed signiifcantly different by initial veriifcation. Contrasted with 40 normal cases, miR-138 and miR-720 were down-regulated in 83 Uygur patients from southern Xinjiang with cervical squamous cell carcinoma (P<0.05),and correlated with lymph node matastasis and vascular invasion (P<0.05), no correlation with age and the range of cervical wall involvement and HPV16 (P>0.05). miRNA-720 was correlated with clinical stage and tumor size (P<0.05); And the commonly targeted gene between miRNA-138 and miRNA-720 was EZH2.Conclusion:miRNA-138 and miRNA-720 were downregulated in Uygur patients from southern Xinjiang with cervical squamous cell carcinoma, and the common target gene was EZH2.The expression of miR-720 and miR-138 were correlated with relevant risk factors of invasion and metastasis.

Objective To discuss the possible molecular mechanisms involved in the protective effects of Biifdobacterium on intestinal tissue of necrotizing enterocolitis (NEC) newborn rats. Methods Seventy-five newborn Sprague-Dawley rats (born within 2 h) were randomly divided into five groups, each group with 15 rats. Group A was the NEC model group, and the rats were fed lipopolysaccharide (LPS) and formula. Group B was the Biifdobacterium treatment group, and the rats were fed LPS and formula and Biifdobacterium micro-capsule. Group C was the artificial feeding control group, and the rats were fed formula. Group D was the Biifdobacterium control group, and the rats were fed formula and Biifdobacterium micro-capsule. Group E was the breastfeeding control group, and the rats were fed rat breast milk by mothers. LPS 30 mg/kg was administered by gavage once per day for 3 days. Bifidobacterium micro-capsules were given as 1×1010 colony forming units/ml by gavage with formula once per day. After fed for 72 h and fasted for 12 h, the five groups of rats were killed by decapitation. Morphological changes in the terminal ileum tissue were observed under a light microscope and intestinal injury was scored. The expression of Toll-like receptor (TLR) 2, TLR4, and nuclear transcription factor (NF)-κB p65 was detected by immunohistochemical methods. Kruskal-Wallis test, analysis of variance, corrected Chi-square test and Fisher's exact test were used for statistics. Results The morbidity of NEC in group A to E was 11/15, 4/15, 3/15, 2/15 and 0/15, respectively;the intestinal injury score in group A to E was 3.37±0.27, 1.53±0.44, 1.75±0.37, 0.92±0.39 and 0.30±0.18, respectively; the expression level of TLR2 in group A to E was 0.35±0.05, 0.30±0.03, 0.32±0.04, 0.30±0.02 and 0.29±0.03, respectively;the expression level of TLR4 in group A to E was 0.48±0.05, 0.34±0.03, 0.36±0.03, 0.37±0.04 and 0.35±0.02, respectively;the expression level of NF-κB p65 in group A to E was 0.43±0.03, 0.29±0.03, 0.35±0.02, 0.32±0.02 and 0.30±0.02, respectively. The differences in NEC morbidity, intestinal injury score, and the expression levels of TLR4, TLR2 and NF-κB p65 among the five groups were all statistically significant (χ2, H or F=23.863, 70.290, 8.803, 38.599 and 75.076, respectively, all P<0.05). The values in the NEC model group were all significantly higher than those in the other four groups (all P<0.05). The morbidity of NEC in the Biifdobacterium treatment group compared with the three control groups was not significantly different (all P > 0.05). The intestinal injury score in the Bifidobacterium treatment group was significantly higher than that in the Bifidobacterium control group and the breastfeeding control group (both P < 0.01), but was not significantly different to that in the artificial feeding control group (P > 0.05). The expression levels of TLR4 and NF-κB p65 in the Biifdobacterium treatment group were significantly lower than those in the artificial feeding control group and the Biifdobacterium control group (all P < 0.05), and were not significantly different to those in the breastfeeding control group (P>0.05). The expression level of TLR2 in the Biifdobacterium treatment group compared with the three control groups was not significantly different (all P > 0.05). Conclusions Biifdobacterium may inhibit pathogenic bacteria or regulate the negative feedback of TLR2 to reduce the expression of TLR2 and TLR4 in intestinal mucosa cells, inhibit the NF-κB pathway, attenuate the inflammatory reaction, and play a role in the prevention and control of NEC.
