Objective To analyze the death rate and life loss of injuries in Jinshan District of Shanghai from 1990 to 2023, and to provide a scientific basis for the formulation of injury prevention and control measures. Methods Excel 2010 was used to establish a database for injury death reports in Jinshan District from 1990 to 2023, and the crude mortality rate, standardized mortality rate, age-specific mortality rate, potential years of life lost (PYLL), rate of potential years of life lost (PYLLR) and standardized rate of potential years of life lost (SPYLLR) were calculated. Results From 1990 to 2023, the crude mortality rate due to injuries in Jinshan District was 52.25/100 000, while the standardized mortality rate was 36.95/100 000. Based on the standardized mortality rate, the top four causes of injury-related deaths were traffic accidents, falls, drowning, and suicide. Traffic accidents ranked first as the leading cause of death for both males (19.30/100 000) and females (8.41/100 000). The top cause of death for the 0-14 years old group was drowning, the 15-64 years old group was traffic accidents, and the 65 years old and above was falls. Over the 34-year period, according to SPYLLR, the top four causes of death for both genders were consistently traffic accidents, drowning, suicide, and falls. Conclusion From 1990 to 2023, traffic accidents, falls, drowning, and suicide have been the primary causes of injury-related deaths in Jinshan District, Shanghai. It is essential to develop targeted prevention and control strategies based on the specific characteristics of these injury-related fatalities.

ObjectiveTo investigate the effect of modified Weijingtang on the pyroptosis of RAW264.7 macrophages via the cysteinyl aspartate-specific protease-1 （Caspase-1）/gasdermin D （GSDMD） pathway. MethodLipopolysaccharide （LPS） was used to induce pyroptosis of RAW264.7 cells. The blank group was treated with the blank serum， and the intervention groups were treated with the sera containing different doses of modified Weijingtang. After 24 h， the viability of cells in different groups was examined by the cell counting kit-8 （CCK-8）. The pyroptosis and morphology of cells in each group were observed by a scanning electron microscope and a phase-contrast microscope， respectively. The mRNA and protein levels of nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3）， Caspase-1， and GSDMD in each group were determined by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. The levels of interleukin （IL）-18 and IL-1β in each group were measured by enzyme-linked immunosorbent assay. ResultUnder the electron microscope， RAW264.7 cells presented the best morphology and structure in the blank group and obvious pyroptosis and leakage of cell contents in the model （LPS） group. Compared with the model group， the intervention groups showed reduced pyroptosis to varying degrees， and the high-dose group had the closest cell morphology and structure to the blank group. Under the optical microscope， RAW264.7 cells were spherical in the blank group and irregular with protrusions in the model group. Compared with the model group， the intervention groups showed improved cell morphology， and the cell morphology in the group with the dose of 20% was the closest to that in the blank group. The mRNA and protein levels of NLRP3， Caspase-1， and GSDMD in the model group were higher than those in the blank group （P<0.05）. Compared with the model group， each intervention group showed down-regulated expression of the above indicators （P<0.05）. Compared with the blank group， the model group presented elevated levels of IL-18 and IL-1β （P<0.05）， which were lowered in the intervention （10%， 20%） groups （P<0.01）. ConclusionModified Weijingtang inhibits the pyroptosis of macrophages by down-regulating the Caspase-1/GSDMD pathway and reducing the release of proinflammatory cytokines.

Objective To investigate the value of dietary fiber intake in predicting blood pressure control in patients with hypertension. Methods A prospective observational study design was used to collect patients' 3-day dietary diaries for amount of dietary fiber intake; after tracking for 3 months, 24-hour dynamic blood pressure was recorded and analyzed to obtain the average systolic and diastolic blood pressures. The receiver operating characteristic (ROC) curve was used to evaluate the predictive effect of dietary fiber intake on blood pressure control. Results Complete dietary nutrient intake of 166 cases was obtained, of which 148 cases had blood pressure data. Regression analysis showed that dietary fiber intake had a positive effect on systolic blood pressure (OR=0.897, 95%CI, 0.839 to 0.960), and also had a good predictive effect on systolic blood pressure [area under the curve (AUC) was 0.715, sensitivity was 60.0%, and specificity was 76.9%]. Dietary fiber intake did not have a positive effect on diastolic blood pressure. Conclusion Dietary fiber intake has a good predictive effect on the control of systolic blood pressure in hypertension patients, but it fails to effectively predict the control of diastolic blood pressure.

OBJECTIVE To establish the method for monitoring the dynamic changes of odor components in Cornus officinalis during processing . METHODS The decoction pieces of C. officinalis with different processing time were prepared by the wine steaming method . The dynamic changes of odor components were obtained by using ultra -fast gas electronic nose ；odor components were identified by comparing with AroChemBase database ；the dynamic changes of odor compounds were analyzed in combination with peak area ，and the chemical pattern recognition analysis were carried out . RESULTS A total of 12 common peaks of odor components were identified in the fingerprints of raw C. officinalis，and 21 in the fingerprints of decoction pieces of C. officinalis. Eight odor components with the high proportion of peak area during processing were ethanol ， isopropyl alcohol ， 2- methylpropylaldehyde，ethyl acetate ，2-methylbutanal，isoamyl alcohol ，2-hexanol and furfural ，among which ，the peak areas of ethanol，isoamyl alcohol and 2-hexanol showed a trend of first increasing and then decreasing ；at 24 h of processing ，their peak areas were still higher than those of raw products . The peak areas of ethyl acetate ，2-methylbutanal and furfural nearly increased with the increase of processing time . Variable importance in projection of above eight odor components were all greater than 1. CONCLUSIONS The method is established for monitoring the dynamic changes of odor components of C. officinalis during processing. Eight odor components such as ethanol can be used as monitoring indicators of C. officinalis dring processing .

OBJECTIVE：To pro vide reference f or resolving structural imbalance of “supply and demand dislocation ”in each stage of new drug R&D funds in China. METHODS ：Through analyzing the fund demand in each stage of new drug R&D and the problem of “supply and demand dislocation ”in detail ，a financing scheme matching the fund demand of each stage was designed ， and analyzed with the financing process of “Wanke”. RESULTS & CONCLUSIONS ：In the basic stage of new drug R&D ，there was a large demand for funds ，but there were great technical risks ，transformation risks and investment risks ，little attention and support from investors ，resulting in the lack of R&D funds in this stage. It is suggested to increase the investment of R&D enterprises themselves. In the stage of new drug discovery ，the risks of R&D and investment were still high ，more funds were needed and funds were in short supply. It is suggested to attract more venture capital into this stage. From preclinical stage to clinical stage Ⅱ，there was a greater demand for funds. It is suggested that this stage should mainly rely on venture capital and pledge financing with patents. From the clinical stage Ⅲ to pre-marketing ，R&D had entered the mature stage with less investment risk. Therefore ，more venture capital could be obtained in this stage ，and there was a situation of excess capital. At this time ，in addition to venture capital ，R&D enterprises can also choose listing financing. In the post-marketing stage ，the sales right of a certain region in the product sales link could be transferred to provide new reserve funds for the next round of new drug R&D ，so as to achieve a virtuous circle of R&D activities. One of the reasons for the success of “Wanke”R&D financing lied in the combination of various financing methods in the financing process. It is suggested that China should improve the financial financing system and patent value evaluation system at the national level ，so as to promote the drug patent pledge financing in China as soon as possible. Finally ，new drug R&D institute must establish the concept of independent innovation ，speed up the output of technological innovation results ，so as to achieve the improvement of China ’s independent R&D capability.
