Objective:
To investigate the mortality of malignant tumors, diabetes, cardio-cerebrovascular diseases and chronic respiratory diseases and trends in probability of premature mortality due to these four chronic diseases in Jiangmen City, Guangdong Province from 2012 to 2021, so as to provide the evidence for perfecting the chronic disease control strategy.
Methods:
The mortality of malignant tumors, diabetes, cardio-cerebrovascular diseases and chronic respiratory diseases among household registered residents in Jiangmen City from 2012 to 2021 were collected from the Guangdong Provincial Population Death Information Registration Management System, and the crude mortality, standardized mortality by the population of the Fifth National Population Census in China in 2000 and probability of premature mortality were calculated. The trends in mortality and probability of premature mortality were analyzed using average annual percent change (AAPC), and whether achieving the targets for the probability of premature mortality due to four chronic diseases in 2025 and 2030 were evaluated.
Results:
A total of 226 012 deaths occurred due to four chronic diseases in Jiangmen City from 2012 to 2021, and the overall crude mortality and standardized mortality rates were 569.22/105 and 283.29/105, with a reduction in the probability of premature mortality from 15.04% to 12.05% (AAPC=-2.403%, Z=-7.603, P<0.001). The probability of premature mortality due to four chronic diseases decreased from 19.21% to 16.38% in males, and from 10.42% to 7.58% in females (AAPC=-1.893% and -3.085%, Z=-5.262 and -9.811, both P<0.001). The probability of premature mortality due to diabetes appeared a tendency towards a rise (AAPC=2.317%, Z=2.548, P=0.034), and the probability of premature mortality due to cardio-cerebrovascular diseases showed a tendency towards a decline (AAPC=-4.826%, Z=-13.590, P<0.001), while no significant changing trend was seen in the probability of premature mortality due to malignant tumors or chronic respiratory diseases (AAPC=-0.751% and -2.461%, Z=-1.532 and -1.730, P=0.125 and 0.122). The predicted probability of premature mortality due to four chronic diseases was 10.92% in 2025 and 9.66% in 2030 in Jiangmen City, which were both lower than the target (11.21% and 9.81%).
Conclusions
The probability of premature mortality due to four chronic diseases appeared a tendency towards a decline in Jiangmen City from 2012 to 2021, which can reach the target in 2025 and 2030. Males should be given a high priority for interventions of chronic diseases, and diabetes control should be reinforced.

Hepcidin are small cationic peptides with antibacterial activity expressed mainly in the liver of living organisms, and they play important roles in the host's immune response against microbial invasion and regulation of iron metabolism. Thus, they are considered to be good substitutes for traditional antibiotics. It is a good choice that the antimicrobial peptides are prepared by recombinant DNA expression. In the present study, two hepcidin mature peptide cDNAs from channel catfish (Ictalurus punctatus) (mCH) and tilapia (Oreochromis niloticus) (mTH) were connected by SOE-PCR in order to obtain more recombinant hepcidin with broad antimicrobial spectrum, and EcoR I and Not I sites were added to 5'- and 3'- ends of the fragment, respectively. The recombinant eukaryotic expression vector "pPIC9K-mCH-mTH" was successfully constructed, and transformed into Pichia pastoris GS115. The transformants containing multicopy gene insertion were selected by using different concentrations of G418 and other specific mediums, and identified by PCR for yeast genomic DNA. Expression was induced by adding 1% methanol at 30 degrees C for different times. Tricine-SDS-PAGE analysis demonstrated that the most appropriate expression time was 72 h, at which a high expression yield (77 mg/L) for the target protein was exhibited. The highly purified target protein was obtained from the fermentation supernatant by SP-Sepharose cation exchange chromatography. Bacteriostatic activity assay demonstrated that the fermentation supernatant containing the target protein and purified recombinant target protein had bacteriostatic activities against gram-positive and gram-negative bacterium. The present result provides the important initial value for industrial production of hepcidin antimicrobial peptide.

Objective:To observe the effects of lentivirus-mediated shRNA silencing of PRL-3 gene on the proliferation, migration and invasion of lung cancer A549 cells and regulation of epithelial-mesenchymal transition (EMT) signaling pathway.Methods:Lung cancer A549 cells were transfected with lentiviral interference vector carrying PRL-3 shRNA to build a stable PRL-3-silencing cell line. The cells were divided into blank control group, NC shRNA group (negative control group) and PRL-3 shRNA group (PRL-3 inhibiting RNAi lentivirus group). CCK-8 method, colony formation assay, Transwell and invasion chamber assay were performed to detect the proliferation, migration and invasion ability of A549 cells respectively. The expressions of E-cadherin and Snail mRNA were detected by real-time fluorescent quantitative PCR.Results:The stable PRL-3-silencing cell line was successfully constructed. The knockdown efficiency of PRL-3 gene in the PRL-3 shRNA group reached 83.5%. CCK-8 method detected the proliferation ability of A549 cells, and the results showed the 24 h absorbance ( A) values of A549 cells in the blank control group, NC shRNA group and PRL-3 shRNA group were 0.296±0.008, 0.342±0.007 and 0.292±0.004, with a statistically significant diffe-rence ( F=106.300, P<0.001), and the PRL-3 shRNA group was significantly lower than the NC shRNA group ( P<0.001); at 48, 72, 96 h after transfection, the cell proliferation abilities of the PRL-3 shRNA group were also significantly inhibited. Colony formation assay showed that the numbers of colony formation in the blank control group, NC shRNA group and PRL-3 shRNA group were 166.7± 6.7, 158.0±6.1 and 119.7±1.5 ( F=67.290, P<0.001). The ability of colony formation of the PRL-3 shRNA group was significantly lower than that of the NC shRNA group ( P<0.001). The numbers of migrated cells in the blank control group, NC shRNA group and PRL-3 shRNA group were 100.0±1.9, 98.8±1.9 and 44.6±7.6 ( F=430.300, P<0.001). The migration ability of the PRL-3 shRNA group was significantly lower than that of the NC shRNA group ( P<0.001). The numbers of invaded cells in the three groups were 117.7±4.1, 113.1±6.6 and 55.6±8.4 ( F=247.200, P<0.001). The invasion ability of the PRL-3shRNA group was significantly lower than that of the NC shRNA group ( P<0.001). Real-time fluorescent quantitative PCR detection results showed that after silencing the expression of PRL-3, the relative expression level of E-cadherin mRNA in A549 cells was significantly up-regulated, and the level of Snail mRNA was significantly down-regulated. Conclusion:PRL-3 silencing can inhibit the proliferation, migration and invasion of A549 cells effectively. PRL-3 may affect the invasion of lung cancer cells through the EMT pathway.

OBJECTIVE To provide a practical action plan which can prevent and control the similar occurrence through studying the epidemiological characteristics of a norovirus-induced diarrhea outbreak in the wards of our hospital. METHODS To obtain the information about the epidemic situation of norovirus involving 15 patients in the two wards of our hospital, during the period from Nov 12 to 15, 2006. RESULTS It was a norovirus gastroenteritis outbreak in the 8 cases among 15 patients and there were other 7 sporadic cases. The consummate monitoring system on nosocomial infection could gain the information of disease, and be very helpful to control its transmission. Beijing Municipal Center for Quality Control and Improvement of the Management of Nosocomial Infection was known the information and shared it among different kinds of hospitals. Thus an unnecessary panic was avoided in Beijing at that time. CONCLUSIONS The social factor, senile situation and immunocompromise are the causes of this norovirus outbreak. The effective control measures and the information exchange in time could prevent the spread of infection. It is shown that the nosocomial infection monitoring network could catch the epidemic tendency of nosocomial infection sensitively, so to strengthen the monitoring network is the key.
