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.

Malignant cerebral edema can lead to increased intracranial pressure, rapid deterioration of neurological function, and even the formation of cerebral hernia. It has the characteristics of high mortality and disability rates, and is a common cause of poor prognosis in patients with acute massive cerebral infarction. Early decompressive craniectomy can effectively improve the neurological outcomes of patients with malignant cerebral edema. Therefore, early prediction of malignant cerebral edema is crucial. This article reviews the formation mechanism and related imaging manifestations of malignant cerebral edema, in order to provide reference and assistance for the early diagnosis and reasonable treatment of malignant cerebral edema after massive cerebral infarction.

Objective:To evaluate dental and skeletal changes following slow maxillary expansion with quad helix using Cone-Beam computer tomography (CBCT).Methods:13 patients(5males and 8 females,mean age 14.38 ±2.22 years)requiring maxillary ex-pansion as a part of their comprehensive orthodontic treatment were included.Each patient had CBCT images taken pre-(T1 )and post-(T2)maxillary expansion with quad helix.Changes of the distances between bilateral canines,first premolars,second premo-lars,first molars,the width of basal bone and palatal suture were measured.paired t-test results were analyzed using SPSS 17.0 soft-ware.Results:The distances between the 4 bilateral teeth increased by (2.47 ±1.05)mm,(2.97 ±1.90)mm,(2.79 ±1.21) mm and (3.15 ±1.15)mm,the apical distances decreased by (1.19 ±0.40)mm,(2.12 ±0.68)mm,(2.02 ±0.65)mm and (1.34 ±0.63)mm,respectively.The inclination of the first molars were decreased by (4.45 ±2.86)°and (4.02 ±1.45)°on the left and right side respectively.The width of basal bone and palatal suture increased by (2.37 ±0.96)mm and (1.21 ±0.50)mm respectively,the differences between T1 and T2 were all statistically different(P <0.001).Conclusion:Quad helix expands maxil-lary arch by greater dental changes than by skeletal changes.

Glymphatic system is a fluid transport and material clearance system found in recent years. It promotes the flow and exchange of cerebrospinal fluid and interstitial fluid, remove metabolic waste, and maintain the stability of the internal environment of the brain through the perivascular space and aquaporin 4 on astrocytes. Recent studies have shown that the glymphatic system plays an important role in the intake and discharge of the fluid in brain, and the changes of glymphatic system may be an important reason for brain edema after ischemic stroke. This article reviews the pathophysiological mechanism and related therapeutic targets of glymphatic system in the formation of cerebral edema after ischemic stroke, in order to provide new ideas for the treatment of cerebral edema after ischemic stroke.

Objective To observe the effect of Rhy-SLN on the proliferation of rat vascular smooth muscle cells (VSMC) induced by TGF-β1, and explore the mechanism. Methods The primary culture of rat thoracic aortic vascular smooth muscle cells was studied by tissue block culture method. The cells were divided into the control group, TGF-β1 group, TGF-β1+ the high, medium and low dosage groups of Rhy-SLN. In addition to the control group, the cells of the other groups were involved in the intervention of TGF-β1 of 20 g/L, and the high, medium and low dosage groups of Rhy-SLN cells were involved in the intervention of 25, 50, 100 mg/L of the hook teng solid lipid nanoparticles. After 24 hours of culture, MTT assay was used to detect cell proliferation inhibition rate in each group, and the cell cycle was detected by flow cytometry. The expression of c-myc and c-Fos protein in each group was detected by Western blot method. Results Compared with the TGF-β1 group, the absorbance value (0.457 ± 0.046 vs. 0.975 ± 0.049) of TGF-β1+ rhy-sln high dose group significantly decreased (P<0.01); the number of S phase cells (15.87% ± 2.47%, 15.23% ± 1.69%, 17.02% ± 2.87% vs.38.58% ± 2.68%)of TGF-β1+rhy-sln in each dose group significantly decreased(P<0.01);The c-myc(48.65 ±3.65,50.69 ± 4.16,55.29 ± 3.67 vs.68.21 ± 3.25)and c-Fos(38.78 ± 4.25,43.56 ± 3.69,46.58 ± 3.57 vs.66.54 ± 4.09) of the TGF-β1+ rhy-sln each dose group significantly decreased (P<0.01). Conclusions The Rhy-SLN can inhibit the proliferation of VSMC in rats induced by TGF-β1.Its mechanism is related to the conversion of G0/G1 phase to the S phase and the expression of the reduction of c-myc and c-fos protein.

Objective: To establish a risk assessment system for the prevention and control of infectious diseases in primary and secondary schools in Tianjin and reduce the risk of infectious disease prevention and control through risk assessment and control. Methods: Based on the failure modes and effect analysis method, a quantitative risk assessment of infectious disease prevention and control in 45 primary and secondary schools in Tianjin was carried out. Risk based supervisory process was assessed, while control effect was evaluated for contined improvement in the prevention and control of infectious diseases in the primary and secondary schools. Results: The top three risk aspects found in the infectious disease prevention and control system in primary and secondary schools in Tianjin included failure to provide sanitation professionals (82.22%) in accordance with regulations, no hand sanitizer or disinfectant (35.56%) in wash basins, and drinking water related products without approval (28.89%). The results of the risk assessment indicated that the three risk aspects with the highest risk priority number (RPN) included failure to provide health professionals( n = 144), no morning and afternoon inspection arrangement( n =126), and low quality of morning and afternoon inspections( n =126). After optimizing the supervision measures for the risk aspects with a detectable degree≥7 points, a quantitative risk assessment was carried out again, the RPN values of all risk points fell below 125, indicating reasonable control effect. Conclusion Based on the failure mode and effect analysis method, the establishment of a risk assessment system for the prevention and control of infectious diseases in primary and secondary schools and regular risk assessments can timely detect risk aspects in the infectious disease prevention and control, to promote effective prevention of infectious diseases in schools.
