Objective:
To investigate the trends in incidence of malignant tumors in Yuyao City, Zhejiang Province from 2011 to 2018, so as to provide insights into formulation of the malignant tumor control strategy.
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.

Laser scanning confocal microscope (LSCM) is currently the only equipment to observe fluorescence. However, this technique has disadvantages such as high cost and long test process. In this study, we developed a new system of laser-induced fluorescence (LIF) for microfluidic chip applied to detecting the expression of green fluorescent protein (GFP) in Bacillus subtilis. This novel system was comprised of laser device, optics unit, microfluidic chip, photomultiplier and computer treatment unit. The tests indicated that microfluidic chip could detect the expression of GFP as sensitively as LSCM in Bacillus subtilis. Moreover, this LIF detection system could instead of PCR to identify the positive clone in this special case. Nevertheless, the LIF system only was suitable to detect the fluorescent strength of GFP, and could not meet the request of some cases for example protein location. Therefore, this system will be applied in environmental detection with microbe, drug discovery and other cases.

This study was undertaken to assess the effect of different surface microtopograph of Ti-Nb-Zr-Sn alloy on the biological behavior and soft tissue integration of rabbits' lacertus fibroblast. The lacertus fibroblasts of Achilles tendon of rabbits were cultured and inoculated on the surface of smooth Ti-flake (control group), and on the surface of sand blast, microgrooves, thread Ti-flakes respectively (3 treatment groups). The cell's growth ratio and attaching status were examined by MTT test and scanning electron microscopy (SEM). The rabbits' lacertus fibroblasts proliferated regularly on the surface of Ti-flakes, and most results of their inter-group comparison showed statistically significant difference (P<0.05), thus indicating the different effects of different surface microtopographs on cell's proliferation; By SEM, the cells were noted to have no obvious directivity on smooth surface; they attached irregularly on the sand blast surface. But in the other two groups, they were oriented regularly along the texture. The cells were almost shuttle-like on the four kinds of surface except for a part of irregular cells on the sand blast surface, and there were plentiful cell-cell junctions. Under high power lens, we found cells with limpid microvilli in the experiment samples. Owing to the cell's fast proliferation and regular attachment in the experiment, we concluded that the regular microgrooved surface was more suitable for meeting the requirement of the soft tissues' physiological function.

OBJECTIVE:
To investigate the relationship between apoptosis of myocardial cells in spontaneously hypertensive rats (SHRs) and the expressions of Bcl-2 and Bax protein, and the protective effect of stellate ganglion block on apoptosis of myocardial cells.
METHODS:
A total of 32 ten-week-old male SHRs were assigned randomly into 4 groups: a left stellate ganglion block group (group LS), a right stellate ganglion block group (group RS), a captopril group (group D) and a control group (group C). The arterial systolic blood pressure was measured by ALC-NIBP system. After 10 weeks, all rats were anaesthetized by 3% pentobarbital sodium, cardiomyocyte apoptosis index of left ventricle was assessed by TUNEL, and the localization of myocardium Bcl-2, Bax was investigated by immunohistochemistry.
RESULTS:
Compared with group LS and C, the apoptotic index decreased (P<0.05). SHR myocardial expression of Bcl-2 significantly increased (P<0.05), Bax expression significantly decreased (P<0.05) and Bcl-2/Bax was significantly higher (P<0. 05) in group RS.
CONCLUSION
Bcl-2 and Bax play an important role in the apoptosis of myocardial cells in SHRs. Right stellate ganglion block can reduce the apoptosis of myocardial cells and reverse the reconstruction of the left ventricle in SHRs via regulation of apoptosis-related gene proteins.

OBJECTIVE:
To determine the effect of stellate ganglion block on reconstruction of the left ventricle in spontaneously hypertensive rats (SHRs).
METHODS:
Thirty-two 10-week-old male SHRs were randomly assigned into 4 groups: a left stellate ganglion block group (group LS), a right stellate ganglion block group (group RS), a captopril group (group D) and a control group (group C). The arterial systolic blood pressure (SBP) was measured by ALC-NIBP measuring system. After 10 weeks, we observed the left ventricular mass index (LVMI), myocardial pathologic changes, and detected the endothelin (ET-1) and endothelial nitric oxide synthase (eNOS) level in the left ventricle by radioimmunoassay and the collagen protein level in the left ventricle by immunohistochemical method.
RESULTS:
Compared with group LS and group C, the LVMI in group RS was lowered most notably (P<0.05) and pathological changes were improved obviously. The expression of eNOS in group RS was significantly increased and ET-1 significantly decreased (P<0.05) compared with that in group C and group LS. The expression of type I collagen fibers in group RS was significantly lower and type III collagen fibers significantly higher (P<0.05) when compared with that in group C and LS.
CONCLUSION
Right stellate ganglion block can not only decrease the arterial pressure but also reverse the reconstruction of the left ventricle.

With the improvement of the quality of clinical diagnosis and treatment, the traditional scheduled "ward round" mode cannot meet the demands for real-time monitoring of acute and critically ill patients. This paper introduces the Storm, a real-time data stream processing technology and its application in the real time disease early warning system. By collecting the clinical data flow and calculating the MEWS scores in real time, the system can identify the potential deterioration of the disease, and promptly notify the medical staff. Score calculation results can be stored for further analysis and presentation as well.
