Methods Analysis was made on the prevalence of thyroid cancer in Jing′an District in 2014 and its incidence and death trend from 2009 to 2014 based on the data of Shanghai Cancer Registration and Reporting System. Results From 2005 to 2014, the total number of thyroid cancer cases in Jing′an District were 2 430, ranking fourth of all malignant tumors.The crude incidence rate of thyroid cancer was 24.33/100 000, the standardized incidence rate was 16.67/100 000.The ratio of male to female was 0.34 : 1;the difference in incidence between male and female was significant(χ²=579.77, P < 0.01).In different age groups the difference in incidence was also statistically significant(χ²=419.90, P < 0.01).The highest incidence was in 45-64 years old group, followed by 15-44 years old group. Only 155 deaths occurred; the ratio of death to morbidity was 1 : 15.68.Standardized incidence of thyroid cancer was increasing in Jing′an District from 2005 to 2014(trend Chi-square tests, χ²=7.33, P < 0.01).APC was 20.69%(male 23.81%, female 19.44%).The standardized mortality rate from 2005 to 2014 was at a relatively low level, and the trend of change was not statistically significant. Conclusion The government and society should pay high attention to the status of high detection rate and low mortality rate of thyroid cancer.The focus of prevention and control is rational diagnosis and treatment for a large number of thyroid cancer patients.

OBJECTIVETo observe the effect of a microencapsule scaffold capable of sustained release of fibroblast growth factor-2 (FGF-2) and bone morphogenetic protein-2 (BMP-2) in promoting the osteogenic differentiation of rat periosteum-derived stem cells (PDSCs) in vitro.

METHODSPDSCs from 4-week-old SD rats, after identification of the surface markers using flow cytometry, were induced to differentiate into osteoblast, chondroblast, and adipocyte lineages. The differentiated cells were verified by staining with Alizarin red, toluidine blue, alcian blue, oil red O and by immunofluorescence assay. FGF-2/PELA/BMP-2, FGF-2/PELA, PELA/BMP-2 and PELA microcapsules were prepared, examined for surface morphologies using scanning electron microscopy (SEM), and tested for controlled release of FGF-2 and BMP-2 using ELISA. The third passage of PDSCs were cultured in the presence of the aqueous extracts of one of the 4 materials, and alkaline phosphatase (AKP) activity in the culture media was detected at 7 and 14 days of culture; the expression levels of osteogenesis-related genes were quantified with quantitative real-time PCR (qRT-PCR). The osteogenic differentiation ability of the PDSCs cultured with the extracts was compared.

RESULTSThe PDSCs, which expressed mesenchymal stem cell surface markers, were shown to have osteogenic, chondrogenic and adipogenic differentiation potentials. The cells cultured with the extract of FGF-2/PELA/BMP-2 microcapsules showed the highest AKP activity at 7 and 14 days of culture, and their expression levels of OCN and RunX-2 mRNA were the highest among the 4 groups; RunX-2 expression reached its peak level on day 14, and OCN mRNA expression level increased progressively as the culture time extended.

CONCLUSIONFGF-2/PELA/BMP-2 biomimetic controlled release microcapsules preserve the cytokine activities and are capable of promoting the osteogenic differentiation of rat PDSCs.

Objective To study the combined use of indocyanine green (ICG) fluorescence imaging and intraoperative ultrasound in laparoscopic tumor ablation.Methods This retrospective study was conducted between May 2016 and December 2017 on 81 patients with primary liver carcinoma,metastatic liver cancer and hepatic hemangioma who underwent laparoscopic tumor ablation using fluorescence imaging combined with intraoperative ultrasound guidance at the Union Hospital,Tongji Medical College,Huazhong University of Science and Technology.Preoperative venous injection of ICG was used to result in detection of intraoperative positive staining.Results Of 36 patients with primary liver carcinoma,the intrabepatic lesions in 20 patients could not be detected under fluorescence imaging.The ablation was performed under intraoperative ultrasound guidance.However,for all the subcapsular lesions in 16 patients,including 15 patients with tumors with non-distinguishing boundaries under the bright-field model,the lesions were captured on fluorescence imaging.Of 18 patients with metastatic liver cancer with 54 lesions,all the intrahepatic and subcapsular lesions were not stained by ICG,but the subcapsular lesions could be distinguished by staining of the surrounding liver tissues.Of 27 patients with subcapsular hepatic hemangiomas,the lesions were not stained but they could be distinguished by staining of the peripheral liver tissues.All laparoscopic treatments for the 81 patients were performed successfully without conversion to laparotomy.The average ablation time for a single lesion was (8.5 ± 3.5) minutes.The intraoperative blood loss was 0～20 ml.Two patients developed intraoperative subcutaneous emphysema and 1 patient hemoglobinuria.There was no postoperative bleeding,postoperative renal insufficiency,bile leakage and significant collateral tissue damage.Conclusions Laparoscopic ultrasound guided tumor ablation resulted in low intra-and post-operative complications.The procedure was safe and effective.Ultrasound combined with fluorescence imaging clearly distinguished tumors from the adjacent normal tissues.This technique is clinically useful.

OBJECTIVETo explore the effect of Compound Tongtu Granule (CTG) on intestinal permeability in elderly sepsis patients.

METHODSEighty elderly sepsis patients were randomly assigned to the experimental group and the control group by randomized double blinded method, 40 in each group. On the basis of conventional antiseptic treatment program, patients in the experimental group took CTG, while those in the control group took placebos. The dosage for CTG or placebos was 14.3 g each package, one package each time, twice daily for 14 successive days. Patients' abdominal symptoms and signs, levels of serum inflammatory factors (high-sensitivity C-reactive protein and procalcitonin), levels of plasma endotoxin, and the intestinal permeability (IP, represented by urinary lactulose/mannitol excretion rate) were compared between the two groups before and after treatment.

RESULTSAfter 14-day treatment, patients in the experimental group had improved abdominal symptoms, increased frequency of defecation, significantly decreased levels of plasma endotoxin and IP, when compared with the control group (P < 0.05).

CONCLUSIONCTG could improve the intestinal barrier function in elderly sepsis patients.
