Objective:To investigate the expression of Plk1 ( Polo-like kinase 1 ) and Chk1/2 ( Checkpoint kinase 1/2 ) in primary hepatic carcinoma tissue and HepG2 cell. Methods: Using immunohistochemistry chemical method detected expression of Plk1,Chk1/2 protein in 40 cases of primary hepatic carcinoma tissue and 16 cases of non-tumor tissue of liver. Western blot was applied to detect the expression of Plk1 and Chk1/2 protein in HepG2 cells, and gray value was measured by using the quantitative analysis. Results:The positive rate of Plk1,Chk1/2 protein expression in primary hepatic carcinoma was 57. 5%,75. 0% and 22. 5%respectively,compared with positive rate in the liver of non-tumor tissue were 0%,25. 0% and 56. 3%. The expression of Plk1 and Chk1 protein in primary hepatic carcinoma tissue is higher than that in non-tumor tissue of liver,and the difference was statistically sig-nificant( P<0. 05 ) . The expression of Chk2 in primary hepatic carcinoma was lower than that in hepatic non-tumor tissue, and the difference was statistically significant(P<0. 05) too. The expression of Plk1,Chk1/2 protein were detected in HepG2 cells and the relative expression rate of Plk1,Chk1/2 protein were 0.39±0.0226,0.08±0.0249 and 0.01±0.0066 respectively,the difference between them was statistically significant. The expression degree was Plk1>Chk1>Chk2. Conclusion: Plk1,Chk1 protein in primary hepatic carcinoma was up-regulated,while Chk2 protein was down-regulated in these tissues. The expression degree was Plk1> Chk1>Chk2. There were relatively selective expression in primary hepatic carcinoma tissue of Plk1,Chk1 protein,then Plk1 and Chk1 might be ideal targets for therapy of primary hepatic carcinoma.

Objective The person's Mesangial Proliferative Glomemlonephritis (MsPGN) were divided into 3 types based on clini- cal manifestations: nephroticsyndrome, hematuria and proteinuria. To investigate the expression of CD11a, CD11b, CD62L and its signifi- cance in the kidneys patients with MsPGN. Methods CD11a, CD11b and CD62L expression in blood of MsPGN patients (n=35) were investigated by flow eytometry method, and the changes of these proteins in kidney were surveyed. Results In MsPGN, CD11a and CD11b expression in blood were significandy lower and CD62L expression in blood were markedly higher than that in normal humans. And the renal glomeruli of MsPGN also expressed CD11a, CD11b and CD62L. Conclusion The expression of CD11a, CD11b and CD62L are abnormal in MsPGN, and apoptosis may play certain role in the pathogenesis of MsPGN.

Bacteria translocation (BT) induced enterogenous infection in multiple organs dysfunction syndrome (MODS) is closely related with the stress pyemia and MODS. For prevention of BT, western medicine stresses to improve the blood and oxygen supply of intestinal tract, mucosa protection, and application of microorganism preparation, while traditional Chinese medicine could also win good effect by using such drugs as rhubarb, red sage root, and compound decoctions.

Objective: To understand the current situation of breakfast consumption and its influencing factors in primary and middle school students in a poor rural area in a city in Guizhou Province, and to provide scientific basis for child nutrition education and intervention. Methods: A stratified cluster sampling method was used to conduct a questionnaire survey of breakfast behavior and influencing factors among 2 833 students from 3 primary schools and 3 middle schools in a area of Guizhou Province from April to June 2019. Results: The most frequently consumed breakfast was rice noodle products(71.66%), followed by fresh vegetables(45.89%), milk(35.55%), meat/egg/fish(29.33%), beans(19.52%), and fresh fruits(18.74%). The proportion of having breakfast everyday among elementary and middle school students who was 62.97%, and having breakfast 4-6 days peer week was 22.80%, and 14.23% with ≤3 days peer week, and the proportion of boys who ate breakfast every day(65.07%) was higher than girls(61.00%)(χ2=10.01, P<0.05). The proportion of low quality breakfast was 71.87%, and girls(73.68%) were higher than boys(69.94%)(χ2=9.29, P<0.05). Logistic regression analysis showed that grade of school, boarding school, and sleep quality are all influencing factors for whether to eat breakfast every day; grade of school, whether to stay at school were factors that affect breakfast quality(P<0.05). Conclusion The frequency and quality of breakfast need more improvement among middle and primary school students in a poor rural area of a city in Guizhou Province. Students, parents, and teachers should be educated on nutrition to promote healthy eating and sleeping habits and improve student health.

Objective:To investigate the clinical values of laboratory inflammation indicators including lymphocyte count, C reactive protein (CRP), serum amyloid A protein (SAA), and procalcitonin (PCT) in the diagnosis and treatment of 2019 novel corona virus disease (COVID-19) patients.Methods:The data of clinical characteristics of 77 hospitalized COVID-19 patients were collected from February to March 2020. According to the guidelines for diagnosis and management of COVID-19, these patients were divided into moderate type (49 cases) and severe type (28 cases). Among them 19 cases were discharged. The differences of lymphocyte count, CRP, SAA and PCT among moderate, severe and discharged groups were compared. The indicators with better predictive value for disease development and prognosis were screened out by logistic regression and receiver operating characteristic curve (ROC) analysis.Results:The severe patients had lower lymphocyte count compared to the moderate patients ( P=0.000), while their CRP ( P=0.000), SAA ( P=0.000) and PCT positive rate ( χ2=11.003, P=0.001) were significantly higher; The lymphocyte count of discharged patients was much higher than that of moderate ( P=0.001) and severe ( P=0.000) patients, while CRP ( P=0.036, P=0.000) and SAA ( P=0.002, P=0.000) were dramatically lower; Although the discharged patients had much lower PCT positive rate than severe patients ( χ2=6.891, P=0.009), they were not significantly different from moderate patients ( χ2=0.169, P=0.681). Logistic regression analysis showed that the increased SAA and CRP were both risk factors for predicting severe illness, but the decreased SAA were demonstrated as an independent indicator for discharge. The ROC curve analysis showed that the sensitivity and specificity of SAA for diagnosis of severe patients were 85.71% and 87.76%, whereas CRP were 82.14% and 93.88%. Further, the sensitivity and specificity of SAA for predicting discharge were 100% and 57.89%. Conclusions:The laboratory inflammation indicators such as lymphocyte count, CRP, SAA and PCT had important clinical significance for the diagnosis and treatment of COVID-19 patients. Among them, SAA was demonstrated as an independent indicator with high sensitivity for evaluating the disease progression and prognosis.

Objective To examine the association of pre?pregnancy body mass and weight gain during pregnancy with macrosomia. Methods From January 2015 to December 2015, a total of 20 477 pregnant women were recruited by probabilistic proportional scale sampling with simple randomization in Sichuan, Yunnan and Guizhou Provinces. Basic information of pregnant women, weight gain during pregnancy and weight of newborn were collected. A multiple logistic regression model was used to assess the association between the pre?pregnancy body mass and gestational weight gain indicators with macrosomia. Results 20 321 mother?infant were included in the final analysis. 20 321 pregnant women were (30.09 ± 4.10) years old and delivered at (39.20 ± 1.29) weeks, among which 12 341 (60.73%) cases were cesarean delivery. The birth weight of 20 321 infants were (3 292.26 ± 431.67) grams, and 970 (4.77%) were macrosomia. The multiple logistic regression model showed that after adjusting for the age of women, compared to the normal weight group in the pre?pregnancy, the overweight and obesity group elevated the risk of macrosomia, with OR (95%CI) about 1.99 (95%CI: 1.69-2.35) and 4.05 (95%CI: 3.05-5.39), respectively. After adjusting for the age, the pre?pregnancy BMI, delivery weeks, delivery mode and infant's gender, compared to the weight?gain appropriate group, higher weight gain rate in the mid?pregnancy and excessive total gestational weight gain elevated the risk of macrosomia, with OR (95%CI) about 1.99 (95%CI:1.66-2.39) and 1.80 (95%CI: 1.55-2.08), respectively. Conclusion The overweight before pregnancy, obesity before pregnancy, the rate of weight gain in the second trimester and the high total weight gain during pregnancy could increase the risk of macrosomia.

Objective: To analyze the effect and adverse reactions of radiotherapy in patients with primary orbital lymphoma. Methods: A total of 28 patients with primary orbital lymphoma from Tianjin Union Medical Center, the First Central Hospital of Tianjin and Tianjin Dagang Oil Company Hospital between March 2006 and August 2012 were retrospectively analyzed. All the patients received orbital tumor dissection or biopsy, then received radiation therapy. Three patients received chemotherapy with CHOP protocol before radiotherapy. Radiotherapy was delivered routinely with 3D-conformal radiation therapy (CRT) technique with daily 2-2.5 Gy for 5 times per week and 3-5 fields. Total dosage was 20-50 Gy. There were 18 cases of 30 Gy, 1 case of 22 Gy, 1 case of 25 Gy, 1 case of 20 Gy, 1 case of 28.8 Gy, 3 cases of 40 Gy, 1 case of 42 Gy, 1 case of 46 Gy and 1 case of 50 Gy. Results: All the patients had complete remission (CR) after radiotherapy during follow-up. One patient recurred after radiotherapy of 4 months and received CR with radiotherapy again. One patient died of lung infiltration. Acute complications during radiotherapy were conjunctivitis (28 cases, 100.0%) and keratitis (1 case, 3.6%), long-term complications with ophthalmoxerosis (10 cases, 35.7%) and decreased visual acuity (1 case, 3.6%). Conclusion Radiotherapy is an effective method for primary orbital lymphoma, and the adverse reactions can be tolerated for most patients.
