Background and purpose:Bladder cancer is the most common urological tumor, and its pathogen-esis is still not fully understood. The study was aimed to observe the expressions of key genes in many tumor-associated signaling pathways in normal bladder tissue and bladder carcinoma, and to provide further evidence for the subsequent study of bladder cancer recurrence and metastasis.Methods:Twenty-seven cases of bladder cancer specimens were col-lected, and normal bladder tissues and bladder cancer tissues were distinguished by frozen section. Then, the expressions of 84 genes of cancer-related signaling pathways in bladder cancer tissues and normal bladder tissues were screened by Cancer Pathway Finder PCR Array produced by QIAGEN company.Results:Compared with the normal bladder tissues, the bladder carcinoma tissues had 8 up-regulated genes and 19 down-regulated genes. In this study, the impact of epithe-lial-mesenchymal transition (EMT) signaling pathway was selected as a research direction in which theGSC,KRT14,DSP were up-regulated,SNAI2,SNAI3 were down-regulated. ThereforeGSC,KRT14,DSP,SNAI2 andSNAI3 were chosen as target genes, and verified by qRT-PCR in many examples. The result showed that the expressions ofGSC gene in bladder cancer tissues were up-regulated, but with no statistical significance;KRT14,DSP expressions in bladder cancer were higher than those in normal bladder tissues (P<0.05);SNAI2,SNAI3 expressions in bladder cancer were lower than those in normal bladder tissues (P<0.05), andSNAI3 showed the most obvious expression differences.Conclusion:KRT14,DSP andSNAI3 may play an important role in bladder cancer’s occurrence, development and metastasis.

UNLABELLEDBACKGROUND AND OBJECTIVE Telomerase and CYFRA21-1 may be positively expressed in malignant pleural effusion, but the sensitivity and specificity of single tumor marker were low. The aim of this study is to investigate the diagnostic value of combining determination of telomerase activity and CYFRA21-1 levels in differentiating benign from malignant pleural effusion caused by lung cancer.

METHODS80 patients with malignant and 50 patients with benign pleural effusion were enrolled into this study. The telomerase activity in pleural effusion was tested by means of telomeric repeat amplification protocal-PCR-ELISA (TRAP-PCR-ELISA) and CYFRA21-1 levels were tested by the EIA method. All the results were analyzed by the statistical method.

RESULTSThe levels of telomerase and CYFRA21-1 in malignant pleural effusion was significantly higher than that in benign one (t = 17.252 and t = 13.951, P < 0.001). The sensitivity of telomerase activity testing for diagnosing malignant pleural effusion was 71.3%; the specificity was 86.0% and the overall accuracy was 76.9%. The sensitivity of CYFRA 21-1 testing was 60.0%, the specificity was 78.0% and the overall accuracy was 66.9%. The sensitivity of the combined testing was 90.0%, the specificity was 76.0% and the overall accuracy was 86.9%. The sensitivity and the overall accuracy of combined testing were higher than those of telomerase and CYFRA21-1 testing single (chi2 = 9.002 and chi2 = 19.201, P < 0.01; chi2 = 4.389 and chi2 = 14.647, P < 0.05).

CONCLUSIONThe combined testing oftelomerase with CYFRA21-1 can increase the sensitivity and overall accuracy of differential diagnosis of benign and malignant pleural effusion diagnosis.

Objective:Use linear programming model to predict the allocation of surgical nursing human resources, and optimize the allocation of nursing staff.Methods:This study was a controlled clinical trial. A total of 91 nurses from 5 surgical departments in Affiliated Hospital of Qingdao University were selected by convenience sampling method. The nurses who participated in the scheduling in August and September 2020 were the routine scheduling groups, and in March and April 2021 were the linear scheduling groups. The linear programming model of surgical nursing human resources was established. The LINGO 11.0 software was used to calculate the minimum number of nurses required for the next day operation. According to the predicted results and the requirements of the operation specialty and rank level, the surgical staff was arranged for the next day. The overtime hours of nurses in the routine scheduling groups and the linear scheduling groups were compared and analyzed.Results:The number of on-duty nurses was the same in 4 groups, the overtime hours of the conventional scheduling groups in August and September 2020 and the linear scheduling groups in March and April 2021 were 865 (505, 1 435), 780 (475, 1 355), 650 (460, 910) and 720 (350, 915) min, the difference of overtime hours was statistically significant ( H=13.66, P<0.05). The overtime hours of the routine scheduling group in August 2020 were significantly different from those of the linear scheduling group in March 2021 and April 2021 respectively ( Z=-2.69, -2.55, both P<0.05). The overtime hours of the routine scheduling group in September 2020 were significantly different from those of the linear scheduling group in March 2021 and April 2021 respectively ( Z=-2.62, -2.58, both P<0.05).

Objective: To investigate the effects of different developmental patterns on the increases of thyroid volume in children from different genders and periods, and to explore whether there is a synergistic effect on the initiation of puberty in girls, so as to provide a theoretical basis for reducing the risk of thyroid abnormalities in adulthood. Methods: A multi-stage cluster sampling was used to select a primary school in Minhang District of Shanghai, Haimen City of Jiangsu Province and Yuhuan city of Zhejiang Province. A total of 784 children aged 8-10 years old were included in "8-10 years school-aged children cohort". At the same time, a total of 491 girls aged 11-13 years were included in the "11-13 years adolescent girls cohort". The content of survey on follow-up was consistent with the one on baseline. B-ultrasonography was used to measure thyroid volume. The physical development indexes such as height (H), weight (W) and waist circumference (WC) were measured. The morning urine samples were collected and the urinary iodine content was detected. The changes of body mass index (BMI), waist circumference (WC), and thyroid volume (V) were calculated (d BMI, d WC, and d V, respectively). According to the changes of BMI and WC, the subjects were classified into four types of developmental changes, namely "B-LW-L (low d BMI, low d WC)" "B-LW-H (low d BMI, high d WC)" "B-HW-L (high d BMI, low d WC)" and "B-HW-H (high d BMI , high d WC)". Results In partial correlation analysis, thyroid volume was significantly correlated with BMI and WC at baseline or follow-up(P<0.05). The changes of thyroid volume in 8-10 years old boys were related to the changes of BMI and WC (P<0.05), the changes of thyroid volume in 8-10 year old girls were only associated with the changes of WC (P=0.03), and no association was found in 11-13 year old girls(P>0.05). In multivariate logistic regression analysis, after adjusting for baseline age, region, and differences of urinary iodine, the risk of thyroid volume increasing in B-HW-H was 2.70 times (95%CI=1.29-5.66) higher than that of B-LW-L in boys aged 8-10 years; among girls aged 11-13 years, the risk of thyroid volume increasing in B-LW-H, B-HW-L and B-HW-H were 2.46 times (95%CI=1.31-4.61), 2.16 times (95%CI=1.15-4.03) and 1.79 times (95%CI=1.07-2.99), respectively; there was no interaction between menarche age and developmental pattern on thyroid volume change trend (P=0.49). Conclusion The thyroid volume in children and adolescents increases with the development of physical development. Different developmental patterns and estrogens have certain effects on thyroid morphological changes. To avoid obesity in childhood (especially with central obesity), timely identify and effectively intervene thyroid morphological abnormalities in childhood，and to reduce the risk of thyroid diseases in adulthood.

Objective:To explore the application and effect of multidisciplinary collaboration in patients with tophi during perioperative period.Methods:Forty-five patients undergoing tophaceous gout surgery in our hospital from May to October 2020 were selected as the control group and treated with routine treatment.From November 2020 to April 2021, 41 patients undergoing tophaceous gout surgery in our hospital who were treated with multidisciplinary collaboration management mode were included as the intervention group. Postoperative pain, blood uric acid level, hospitalization expenses, hospitalization days and patient satisfaction were compared between the two groups.Results:After implementing the multidisciplinary integration man-agement mode, the pain score of the patients at 4 hours, 1 day and 3 days after operation was lower than that of the control group [(3.6±1.0) vs (4.1±1.0), t=2.33, P=0.022; (2.5±0.8) vs (3.0±0.6), t=3.85, P<0.001; (1.8±0.5) vs (2.2±0.7), t=3.52, P<0.001], the serum uric acid level was significantly lower than that of the control group at 1 month and 3 months after operation [(355±58) vs (3928±39), t=3.50, P=0.001; (316±48) vs (366±47), t=4.84, P<0.001], the hospitalization days and hospitalization expenses were significantly decreased [(8.90±2.48) d vs (10.62±3.96) d, t=2.44, P=0.017; (1.00±0.13) ten thousand yuan vs (1.11±0.17) ten thousand yuan, t=3.34, P=0.001], and the patient satisfaction was markedly improved (97.6% vs 82.2%, χ2=3.87, P=0.049). Conclusion:The multi-disciplinary collaboration mode in patients with tophi during perioperative period can effectively reduce the postoperative pain, improve the quality of care, promote reha-bilitation, improve the outcome, and reduce the economic burden of patients, which is worthy of popularization and being applied in clinic.
