ABSTRACT
Objective:To characterize the trends in the incidence and mortality of colorectal cancer in Jing'an District of Shanghai， thus optimizing the prophylactic options for this malignancy. Methods:Data from Shanghai Cancer Registration and Reporting System were used to analyze the colorectal cancer prevalence in Jing'an District from 1993 to 2017. Joinpoint software was used to analyze the trends in the standardized incidence rate and mortality rate by calculating the annual percentage of change （APC） and the average annual percentage of change （AAPC）. Results:A total of 13 580 new cases of colorectal cancer were reported in Jing'an District during 1993 and 2017， with an average crude incidence rate of 52.94/105 and a standardized incidence rate of 24.77/105. The total number of deaths was 7 572， with an average crude mortality rate of 29.52/105 and a standardized mortality rate of 12.20/105. The standardized incidence rate of colorectal cancer in Jing'an District from 1993 to 2017 showed an increasing trend （AAPC=1.64%，P<0.001）， and the standardized incidence rate of colorectal cancer in both sexes increased （AAPC： 2.10% in men， 1.04% in women）. The age-standardized mortality rate （ASMR） did not change significantly. The incidence rate of colorectal cancer increased in men in both age groups of 50 to 74 years and 75 years and older， with an AAPC of 2.07% and 3.32%， respectively. However， this was not evident in women of all age groups. The mortality rate of colorectal cancer in men aged 0-49 years， as well as in men and women at 50-74 age groups， decreased significantly， with an AAPC of -7.46%，-1.13%， and -2.72%， respectively. The mortality rate of colorectal cancer in men of 75 years or older showed no significant trend， while that in women of 75 years or older increased （AAPC=2.30%）. Conclusion:The overall standardized incidence rate of colorectal cancer in Jing'an District from 1993 to 2017 was increased， and ASMR did not change significantly. Public health prophylactic options are suggested， including improvement of lifestyle/physical activity and eradication of precancerous lesion polypus in males aged ≥50 years to reduce the incidence of colorectal cancer， and enforcement of second-grade prophylaxis in females aged ≥75 years to decrease the mortality of colorectal cancer.
ABSTRACT
Objective:To analyze the long-term trend of viral hepatitis mortality in Jing’an District of Shanghai， and to provide a reference for viral hepatitis prevention and control. Methods:Mortality rate， standard mortality rate， PYLL and potential years of life lost rate （PYLL‰） of viral hepatitis in Jing’an district of Shanghai from 1976 to 2015 were calculated. The annual percent change （APC） of the mortality and PYLL‰ were analyzed by Joinpoint regression analysis. Results:From 1976 to 2015， there were 1 342 viral hepatitis death cases， including 832 males and 510 females. The average crude mortality rate was 8.31/100 000， and the average age-standardized mortality rate was 5.45/100 000. Among the deaths of viral hepatitis， men had a higher mortality rate， age-standardized mortality rate and PYLL% than women （χ2Pearson=107.34， 112.93， 39.15， all P<0.01）， men were mainly in the age group of 35-64 years （accounted for 62.62%）， while women were mainly in the age group of 65 years and above （accounted for 55.49 %）， and the average death age of men was earlier than that of women （by rank-sum test： Z=-8.879，P<0.01）. After 1990 （except in 2002）， hepatitis B was the main cause of deaths from viral hepatitis， accounting for 75.00%-100%， and the proportion of other and unclassified cases gradually decreased. Overall， the mortality rate of viral hepatitis declined significantly during 1976-2015 （APC=-2.0%，P<0.05）， with the turning point in 2002. The mortality rate of viral hepatitis declined significantly from 2002 to 2015 （APC=-8.1%，P<0.05）. The overall PYLL‰ of viral hepatitis declined significantly during 1976-2015 （APC=-3.7%，P<0.05）， with the turning point in 1992. After 1992， the PYLL‰ of viral hepatitis declined significantly during 1992-2015 （APC=-6.5%，P<0.05）. Conclusion:There has been a significant decline trend of viral hepatitis in the mortality rate in Jing’an District of Shanghai from 2002 to 2015， with hepatitis B as the main cause of death.

ABSTRACT
Fucoidan(FPS) is an effective component of the Chinese patent medicine named Haikun Shenxi, which treats schronic renal failure in clinics, and has the potential anti-aging effects. However, it is still unclear whether FPS can improve renal aging, especially the molecular mechanism of its anti-aging. The human proximal renal tubular epithelial cells(HK-2) in vitro were divided into normal group(N), D-gal model group(D), low dose of FPS group(L-FPS), high dose of FPS group(H-FPS) and vitamin E group(VE), and treated by the different measures, respectively. More specifically, the HK-2 cells in each group were separately treated by 1 mL of 1% fetal bovine serum(FBS) or D-galactose(D-gal, 75 mmol·L~(-1)) or D-gal(75 mmol·L~(-1))+FPS(25 μg·mL~(-1)) or D-gal(75 mmol·L~(-1))+FPS(50 μg·mL~(-1)) or D-gal(75 mmol·L~(-1))+VE(50 μg·mL~(-1)). After the treatment for 24 h, firstly, the effects of D-gal on senescence-associated β-galactosidase(SA-β-gal) staining characteristics and klotho, P53 and P21 protein expression le-vels, as well as adenosine monophosphate activated protein kinase(AMPK)-uncoordinated 51-like kinase 1(ULK1) signaling pathway activation in the HK-2 cells were detected, respectively. Secondly, the effects of FPS and VE on SA-β-gal staining characteristics and klotho, P53 and P21 protein expression levels in the HK-2 cells exposed to D-gal were investigated, respectively. Finally, the effects of FPS and VE on microtubule-associated protein 1 light chain 3(LC3) protein expression level and AMPK-ULK1 signaling pathway activation in the HK-2 cells exposed to D-gal were examined severally. The results indicated that, for the HK-2 cells, the dose of 75 mmol·L~(-1) D-gal could induce the changes of SA-β-gal staining characteristics and klotho, P53 and P21 protein expression levels. That is causing cells aging. FPS and VE could both ameliorate the changes of SA-β-gal staining characteristics and klotho, P53 and P21 protein expression levels in the HK-2 cells exposed to D-gal. That is anti-cells aging, here, the functions of FPS and VE are similar. D-gal could not only induce cell aging but also increase LC3Ⅱ, phosphorylated-AMPK(p-AMPK) and phosphorylated-ULK1(p-ULK1) protein expressions, and activate autophagy-related AMPK-ULK1 signaling pathway. FPS and VE could both improve the changes of LC3Ⅱ, p-AMPK and p-ULK1 protein expression levels in the HK-2 cells exposed to D-gal. That is inhibiting autophagy-related AMPK-ULK1 signaling pathway activation. On the whole, for the human proximal renal tubular epithelial cells aging models induced by D-gal, FPS similar to VE, can ameliorate renal cells aging by possibly inhibiting autophagy-related AMPK-ULK1 signaling pathway activation. This finding provides the preliminary pharmacologic evidences for FPS protecting against renal aging.

ABSTRACT
Improvements in the imaging of neural circuits are essential for studies of network function in both invertebrates and vertebrates. Therefore, CLARITY, a new imaging enhancement technique developed for mouse brains has attracted broad interest from researchers working on other species. We studied the potential of a modified version of CLARITY to enhance the imaging of ganglia in an invertebrate Aplysia. For example, we have modified the hydrogel solution and designed a small container for the Aplysia ganglia. The ganglia were first processed for immunohistochemistry, and then for CLARITY. We examined the compatibility of these techniques and the extent to which the imaging of fluorescence improved using confocal microscopy. We found that CLARITY did indeed enhance the imaging of CP2 immunopositive neurons in Aplysia ganglia. For example, it improved visualization of small, weak immunoreactive neurons deep in the ganglia. Our modifications of CLARITY make this new method suitable for future use in Aplysia experiments. Furthermore, our techniques are likely to facilitate imaging in other invertebrate ganglia.
ABSTRACT
Objective To explore the application value of dynamic enhanced CT technology in diagnosis of hepatic space occupying lesions.Methods A total of 54 cases of patients with hepatic space occupying lesions from January 2015 to October who were treated in our hospital were selected as the research objects,who were carried out CT plain scan and dynamic contrast-enhanced scan.The lesion display rates,and the lesions,blood vessels and tumor characters in the arterial phase,portal phase and delayed phase were recorded and analyzed,respectively.Results The display rate of plain scan was 64.16％,significantly lower than that in the arterial phase of 98.33％,in the portal phase of 81.67％,and in the delayed phase of 78.33％ of the portal phase of dynamic contrast-enhanced scan,and the differences were significant (all P ＜0.01).In the dynamic contrast-enhanced scan,the display rate of the arterial lesions in the arterial phase was higher than those in the portal phase and delayed phase,while that in the portal phase was higher than that in the delayed phase (all P ＜ 0.05).The total detection rate of the lesions of the plain scan was significantly lower than those of the pathological examination and the dynamic enhanced the third phase scan (both P ＜0.01),and the difference of detection rates between the dynamic enhanced the third phase scan and the pathological examination was not significant (P ＞ 0.05).The differences of the definition of edge sharpness,vascular clarity,and density of the lesions between the second phase scan with the third phase scan were significant (all P ＜ 0.05).The diagnosis rates of malignant and benign liver tumors in the third phase scan were significantly higher than those in the second phase scan,and the tumor characters were significantly higher than those in the second phase scan (all P ＜ 0.05).Conclusions Dynamic enhanced CT scan can effectively improve the detection rate of hepatic space occupying lesions and the effects of qualitative diagnosis and differential diagnosis,and reduce the occurrence of missed diagnosis and misdiagnosis.
ABSTRACT
This study investigated the effects of SIRT1 gene knock-out on osteoarthritis in mice, and the possible roles of SREBP2 protein and the PI3K/AKT signaling pathway in the effects. Mice were randomly divided into a normal group and a SIRT1 gene knock-out group (6 mice in each group). In these groups, one side of the knee anterior cruciate ligament was traversed, and the ipsilateral medial meniscus was cut to establish an osteoarthritis model of knee joint. The countralateral synovial bursa was cut out, serving as controls. The knee joint specimens were then divided into four groups: SIRT1control group (group A, n=6); SIRT1osteoarthritis group (group B, n=6); SIRT1control group (group C, n=6); SIRT1osteoarthritis group (group D, n=6). HE staining, Masson staining, Safranin O-Fast Green staining and Van Gieson staining were used to observe the morphological changes in the articular cartilage of the knee. Immunohistochemical staining was employed to detect the expression of SIRT1, SREBP2, VEGF, AKT, HMGCR and type II collagen proteins. SA-β-gal staining was utilized to evaluate chondrocyte aging. The results showed clear knee joint cartilage destruction and degeneration in the SIRT1osteoarthritis group. The tidal line was twisted and displaced anteriorly. Type II collagen was destroyed and distributed unevenly. Compared with the SIRT1osteoarthritis group and SIRT1control group, SIRT1 protein expression was not obviously changed in the SIRT1osteoarthritis group (P>0.05), while the expression levels of the SREBP2, VEGF and HMGCR proteins were significantly increased (P<0.05) and the levels of AKT and type II collagen proteins were significantly decreased (P<0.05). SIRT1 gene knock-out may aggravate cartilage degeneration in osteoarthritis by activating the SREBP2 protein-mediated PI3K/AKT signalling pathway, suggesting that SIRT1 gene may play a protective role against osteoarthritis.

ABSTRACT
Objective To evaluate the influence of different insertion torque values on stress and strain distributions at implant-bone interface. Methods The three-dimensional finite element model of the whole mandible with dental implants for immediate loading was created by CT scanning and self-developed USIS (universal surgical integration system) software. The insertion torque values of dental implants were supposed to be 0、15、25 N•cm3, respectively. The values of Von Mises stress and strain at implant-bone interface were calculated with ANSYS software, when the dental implants were loaded with vertical and buccolingual force at a 45°oblique angle of 150 N. Results When the dental implants under the three insertion torques were loaded with the vertical force, the maximum Von Mises stress was 33.6, 56.4, 69.6 MPa and the maximum strain was 5 157, 8 645, 15 630 με, respectively, while loaded with the buccolingual force, the maximum Von Mises stress was 95.3, 100.6, 108.3 MPa and the maximum strain was 17 110, 18 690, 21 380 με, respectively. Conclusions With the increased torque value of dental implants, the stress and strain at the implant-bone interface were both increased, but the increase was much slower under buccolingual loading than that under vertical loading.

Normal sodium (20 ml x kg(-1)d(-1)) was apply through intragastric administration in group A, F; Flunarizine (0.8 mg x kg(-1)d(-1)), low dosage Wendantang (1 g x ml(-1)d(-1)), large dosage Wendantang (2 g x ml(-1)d(-1)), Flunarizine combined with large dosage Wendantang were respectively apply through intragastric administration in group B, C, D, E. The velocity and viscosity of blood flow of the vertebral arteries, the apoptotic cell and apoptotic protein in the brain were detected before and after the treatment.</p><p><b>RESULTS</b>Satisfactory animal model were obtained in group A, B, C, D, E. The rabbits of group E had the most improvement of the velocity and viscosity of blood flow of the vertebral arteries while at meantime, which had the lowest apoptotic index and apoptotic related protein expression in the brain.</p><p><b>CONCLUSION</b>The routine treatment for the cervical spondylopathy of the vertebral artery combined with eliminat dampness resolv phlegm method could improve velocity and viscosity of blood flow of the vertebral arteries, which maybe relate with reduction of apoptosis in the brain.</p>
