Methods:
Data pertaining to the incidence of malignant tumor in Yuyao City from 2011 to 2018 were captured from the Chronic Disease Surveillance Module of Ningbo Municipal Digital Disease Control and Prevention Platform. The crude incidence, Chinese population-standardized incidence, global population-standardized incidence, cumulative incidence (0 to 74 years of age), and truncated age-standardized incidence (35 to 64 years of age) of malignant tumors were estimated, and the trends in incidence of malignant tumors were analyzed in Yuyao City from 2011 to 2018 using average annual percentage change (AAPC).
Results:
The crude incidence, Chinese population-standardized incidence, global population-standardized incidence, cumulative incidence (0 to 74 years of age), and truncated age-standardized incidence (35 to 64 years of age) of malignant tumors were 433.78/105, 289.37/105, 224.22/105, 25.83% and 83.34/105 in Yuyao City from 2011 to 2018, with AAPC of 5.90%, 3.31%, 3.31%, 2.84% and 4.24%, respectively (all P<0.05), and the incidence of malignant tumors appeared an overall tendency towards a rise. The incidence of malignant tumors increased with age in Yuyao City from 2011 to 2018, and the incidence of malignant tumors was significantly higher in women than in men at ages of 20 to 54 years, while higher incidence was seen in men than in women at ages of 55 years and older. The ten most common malignant tumors included lung cancer, gastric cancer, colorectal cancer, liver cancer, breast cancer, esophageal cancer, thyroid cancer, pancreatic cancer, prostate cancer and cervical cancer, accounting for 78.84% of all malignancies, and the the incidence of lung cancer, colorectal cancer, breast cancer, thyroid cancer, pancreatic cancer and prostate cancer appeared a tendency towards a rise year by year, with AAPC of 8.37%, 5.36%, 6.42%, 24.81%, 5.49% and 18.78%, respectively (all P<0.05).
Conclusions
The of malignant tumors appeared a tendency towards a rise in Yuyao City from 2011 to 2018, and lung cancer, thyroid cancer, specific female cancers, male gastrointestinal and prostate cancers should be given a high priority for cancer control in Yuyao City in the future. Early screening and early diagnosis of cancers should be facilitated among high-risk populations.

Objective:To evaluate the clinical value of radioactive nuclide strontium chloride (89SrCl2) combined with 99Tc-MDP in treating patients with breast cancer and osseous metastasis. Methods:A total of 80 patients with breast cancer and experiencing bone pain from osseous metastasis were randomly categorized into three groups. 22 patients were treated with 99Tc-MDP (99Tc-MDP group), 30 were treated with 89SrCl2 (89SrCl2 group), and 28 were treated with the combination therapy of 89SrCl2 and 99Tc-MDP (combination group). The analgesic effect, remission of bone metastases, and quality of life of patients in the three groups were observed before and after treatment. Side effect was also monitored. Results:In the combination group, the overall pain relief rate and the increase rate of life quality score were 92.9%(26/28) and 78.6%(22/28), respectively. The combination group was statistically significantly different from the two single-treatment groups (P<0.05). The effective rate of metastatic lesions was 46.4%(13/28) in the combination group, which was significantly higher than that in the 99Tc-MDP group (18.2%, 4/22;P<0.05). The effective rate of metastatic lesions was not significantly different between the combination and 89SrCl2 groups (33.3%, 10/30) (P>0.05). Conclusion:The treatment of 89SrCl2 com-bined with 99Tc-MDP can increase the analgesic effect and significantly improve the curative effect without overt side effects in patients with breast cancer and bone metastasis.

OBJECTIVE To study the expression of CSE1L gene sifted from the whole genome expression profiling in the aRNA from homogenous human nasopharyngeal carcinoma (NPC) and non-NPC biopsy tissue samples using semi-quantitative RT-PCR (sqRT-PCR). METHODS CSE1L gene was sifted from the whole genome expression profiling from homogenous NPC and non-NPC biopsy tissue samples. RNA later RNA Stabilization Reagent was used to preserve the tissue samples harvested from the nasopharynx of NPC and non-NPC patients. The samples were microdissected to get the homogenous tissue cells and then the total RNA was isolated from them. The antisense RNA (aRNA) was amplified from the total RNA by “in vitro transcription” (IVT). CSE1L gene expression in the homogenous tumor cells of NPC and the pure epithelial pillar cells of normal nasopharyngeal tissue was investigated by sqRT-PCR. RESULTS The high quality total RNA could be harvested from the microdissected homogenous tissue cells, and then the sufficient aRNA was amplified from it. The expression of CSE1L gene was identified using these aRNA by sqRT-PCR. There were significantdifference between the average expression value of CSE1L in NPC tissue (1.740?1.105) and in non-NPC tissue (0.618?0.183; df=30, t=3.159, P=0.004). The expression of CSE1L gene in the whole expression profiling were 1.056?0.296 in NPC tissue and 0.465?0.835 in non-NPC tissue respectively (df=16, t=4.317, P=0.001) . CONCLUSION The whole genome expression profiling with sqRT-PCR could be used to sift the marker genes from biopsy tissue samples. CSE1L may be as a candidate oncogene in NPC.

BACKGROUND:Rapid loss of liver-specific functions of the cultured hepatocytes limits the development of hepatocyte-based therapies. OBJECTIVE:To establish a three-dimensional culture system based on col agen hydrogel that enables to enhance liver-specific functions for a long period during culture of hepatocytes. METHODS:Hepatocytes were isolated from Sprague-Dawley rats and then encapsulated into liquid type Ⅰcol agen solution that was premixed with hepatocyte growth factor and Dulbecco's modified Eagle’s medium to create hepatocyte/col agen hydrogel compounds. The compounds were inoculated into a 96-wel plate. After gelation, culture medium was added. Light microscope, hematoxylin-eosin staining and transmission electron microscopy were used to examine the morphological characteristics and ultrastructure of the cultured hepatocytes. The cellsupernatant was col ected and tested for albumin secretion and urea synthesis. Periodic acid-schiff staining, immunofluorescence staining and quantitative real-time PCR were also used to further clarify liver-specific phenotype or function of the hepatocytes.RESULTS AND CONCLUSION:(1) Light microscope revealed that hepatocytes were round shape and distributed uniformly in col agen hydrogel. The three-dimensional hepatocyte culture system exhibited similarities to liver-like structure and tight junction were formed between hepatocytes after 14 days of culture. (2) Within the three-dimensional culture system, hepatocytes remained positive for periodic acid-schiff staining, albumin and hepatocyte nuclear factor-4αpositive after 14-day culture, which provided the convincing evidence of highly differentiated primary hepatocytes with functions of glycogen and albumin synthesis. (3) The albumin and urea productions in the three-dimensional culture system had a significantly higher level than in the two-dimensional culture, and could remain at a high level at least for 15 days. (4) The expression levels of hepatocyte-specific genes including Albumin, HNF-4α, Claudin-3, CYP1A1, CYP3A1 and G6P were significantly improved in the three-dimensional culture as compared with the two-dimensional culture. The col agen hydrogel based three-dimensional culture system provides a valuable model to enhance the hepatocyte functional maintenance and lay the foundation for the development of hepatocyte-based therapy for liver disease.
