OBJECTIVE To explore the safety， effectiveness， and cost-effectiveness of elderly patients with sarcopenia receiving Shenling baizhu powder combined with nutrition and exercise intervention， providing a reference for rational clinical drug use. METHODS A total of 237 elderly sarcopenia patients were randomly assigned to an observation group （118 cases） and a control group （119 cases）. Both groups of patients received nutrition and exercise intervention； the observation group added Shenling baizhu powder （6 g each time， three times daily） on this basis. The safety， effectiveness， and cost-effectiveness of the two plans were compared after 3 months. RESULTS Both groups of patients completed the follow-up. Before intervention， no significant difference was observed in skeletal muscle index （SMI）， grip strength， and 6-minute walk test （6MWT） speed between the two groups （P＞0.05）. After intervention， the grip strength of the patients in the observation group was significantly greater than that of the control group （25.05 kg vs. 23.18 kg， P＜0.01）； the treatment response rate of sarcopenia， SMI， and 6MWT speed were higher than those of the control group， butthe differences were not statistically significant （P＞0.05）. The adverse reaction/event rate of the patients in the observation group was lower than that of the control group （14.41% vs. 16.81%， P＝0.611）， but the difference was not statistically significant. Compared with the control group’s plan， the cost of the observation group’s plan was higher （981.25 yuan vs. 913.94 yuan）， and the effect was better （effectiveness rate： 0.618 6 vs. 0.563 0）， with an incremental cost-effectiveness ratio of 1 210.61 yuan. The results of the sensitivity analysis were consistent with the cost-effectiveness analysis results. CONCLUSION Elderly patients with sarcopenia who receive Shenling baizhu powder combined with nutrition and exercise intervention can significantly strengthen grip strength without increasing the incidence of adverse reactions/events. Compared with the control group plan， the observation group needs to spend an additional 1 210.61 yuan for each additional effective patient with sarcopenia.

ObjectiveTo analyze the epidemic characteristics of measles and rubella in Pudong New Area of Shanghai from 2013 to 2022， and to provide data support for the elimination of measles and rubella. MethodsEnzyme linked immunosorbent assay was used to detect IgM antibodies in serum samples. The sequence of 630 nucleotides at the C-terminal of N gene of measles virus was amplified by reverse transcription-polymerase chain reaction and the phylogenic tree was constructed. ResultsA total of 1 529 suspected cases of measles were detected from 2013 to 2022， among which the positive rate of measles IgM antibody was 33.55% （513/1 529）. The highest positive rate （20.73%） was from March to May ， and the positive rate of rubella IgM antibody was 6.80% （104/1 529）. The positive rate of both IgM was higher in males than that in females （P<0.05）. The IgM against measles was mainly detected in 0‒ years old （63.16%， 96/152） and 20‒ years old （45.61%， 161/353）. The IgM against rubella was mainly detected in 10‒20 years old （27.27%， 18/66）. The IgM antibody could be detected more easily from 4 to 28 days after eruption， and the IgM antibody positive rate of measles/rubella from 2020 to 2022 was significantly lower than previous years （2013‒2019）. There were 2 D8 genotype strains， and the rest were H1a gene subtypes. ConclusionThe positive rate of IgM antibodies against measles/rubella in Pudong New Area of Shanghai decreased significantly. People aged 0‒ years and 20‒ years old are more susceptible to measles， and rubella is concentrated in 10‒ years old. It is necessary to strengthen the vaccination of school-age children， in order to achieve the goal of eliminating measles. The age group with high risk of exposure should be checked for vaccination status to ensure the enhanced immunization， and the surveillance of imported measles cases should be strengthened.

OBJECTIVE To investigate the protective effect and potential mechanism of cornuside on diabetic nephropathy （DN） model mice. METHODS Male KK-Ay mice were fed with high-fat and high-sugar diet for two weeks to reproduce the DN model. The successfully modeled mice were randomly grouped into model group， aminoguanidine group （positive control，100 mg/kg） and cornuside group （100 mg/kg）， and male C57BL/6J mice were included as normal group， with 6 mice in each group. Administration groups were given relevant medicine intragastrically， and normal group and model group were given a constant volume of normal saline intragastrically， once a day， for 8 consecutive weeks. The levels of fasting blood glucose （FBG）， 24 h urinary protein， serum interleukin-12 （IL-12）， IL-10， blood urea nitrogen （BUN） and serum creatinine （Scr） were detected； the pathological injury， fibrotic change and glomerular microstructure of renal tissue were observed； the expressions of the receptor of advanced glycation end products （RAGE）， collagen type Ⅳ （COL-Ⅳ） and inducible nitric oxide synthase （iNOS） in renal cortex were detected in each group. RESULTS Compared with normal group， the renal cortex of mice in model group showed obvious inflammatory cell infiltration and fibrotic changes； the mesangial hyperplasia of glomerulus was serious and the basement membrane had a large number of irregular dark dense deposits； the levels of FBG and 24 h urinary protein， the serum levels of IL- 12， BUN and Scr， and the expression levels of RAGE， COL-Ⅳ and iNOS in the renal cortex were significantly increased， while the serum level of IL-10 was significantly decreased （P＜0.01）. Compared with the model group， the renal pathological injuries， fibrotic changes and glomerular microstructure of mice in administration groups were improved significantly， and the above quantitative indexes were generally improved （P＜0.05 or P＜0.01）. CONCLUSIONS Cornuside has a certain protective effect on DN model mice. It can inhibit the inflammatory response， reduce urinary protein excretion， and alleviate renal fibrosis， which may be related to the inhibition of the advanced glycation end products/RAGE signaling pathway.

Objective:To develop an Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses and test its reliability and validity.Methods:Based on the theory of knowledge, attitude, and practice, a preliminary scale draft was formed through a literature review, three rounds of Delphi expert consultation, and a pre-survey. Using convenience sampling, 311 hemodialysis nurses were selected for a survey from December 2022 to February 2023 for item analysis, exploratory factor analysis and reliability testing. Another survey was conducted on 260 hemodialysis nurses from February to June 2023 for confirmatory factor analysis, convergent validity, and discriminant validity testing.Results:The Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses included three subscales and five dimensions, with a total of 33 items. The content validity index at the item level was 0.867 to 1.000, and the content validity index at the scale level was 0.992. After exploratory factor analysis, two, one, and two common factors were extracted from the knowledge, attitude, and practice subscales, with cumulative variance contribution rates of 70.114%, 75.192%, and 67.467%, respectively.Confirmatory:factor analysis showed that the model fitted well. The Cronbach's α coefficients of the three subscales were 0.929 to 0.943, the half reliability coefficients were 0.861 to 0.903, and the retest reliability coefficients were 0.824 to 0.874. Conclusions The Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses has good reliability and validity and can be used to evaluate the physical examination ability of hemodialysis nurses for arteriovenous fistula.

Fruit cracking is a common physiological disease. Many fruits such as tomato, sweet cherry, apple, jujube, pomegranate, and litchi are liable to crack, causing considerable economic loss and agricultural resources waste. The mechanisms of fruit cracking are comprehensive. Some correlations have been observed between susceptibility of fruit cracking and some fruit traits (genetic, fruit size, fruit shape, fruit growth rate, water content, fruit skin characteristics, related gene expression, etc). Also, environmental condition (temperature, light, rainfall, etc) and orchard management (irrigation, sun-shade, mineral, growth regulator, etc) can influence fruit cracking. Here, progress in studies on fruit cracking is reviewed to provide a reference for prevention and control of fruit cracking.

The environmental gas concentration affects the storage period and quality of fruits and vegetables. High concentration CO₂ treating for a long time will cause damage to fruits, However, the specific molecular mechanism is unclear. To analyze the mechanism of CO₂ injury in apple, high-throughput sequencing technology of Illumina Hiseq 4000 and non-targeted metabolism technology were used to analyze the transcriptome sequencing and metabolomics analysis of browning flesh tissue of damage fruit and normal pulp tissue of the control group. A total of 6 332 differentially expressed genes were obtained, including 4 187 up-regulated genes and 2 145 down regulated genes. Functional analysis of the differentially expressed genes confirmed that the occurrence of CO₂ injury in apple was related to redox process, lipid metabolism, hormone signal transduction process and energy metabolism process. Twenty candidate browning genes were successfully screened, among which grxcr1 (md14g1137800) and gpx (md06g1081300) participated in the reactive oxygen species scavenging process, and pld1_ 2 (md15g1125000) and plcd (md07g1221900) participated in phospholipid acid synthesis and affected membrane metabolism. mdh1 (md05g1238800) participated in TCA cycle and affected energy metabolism. A total of 77 differential metabolites were obtained by metabolomic analysis, mainly organic acids, lipids, sugars and polyketones, including 35 metabolites related to browning. The metabolism of flavonoids was involved in the browning process of apple. Compared with the control tissue, the content of flavonoids such as catechin and quercetin decreased significantly in the damaged apple tissue, the antioxidant capacity of cells decreased, the redox state was unbalanced, and the cell structure was destroyed, resulting in browning. The results of this study further enrich the theoretical basis of CO₂ damage, and provide reference for the practical application of high concentration CO₂ preservation technology.

Objective:To understand the epidemiological characteristics of infectious diarrhea pathogens in Pudong New Areas of Shanghai from 2013 to 2017 to provide evidence for control and prevention of the disease.Methods:From Jan 2013 to Dec 2017, active surveillance program on diarrhea was conducted in 14 sentinel hospitals (three tertiary-level and nine secondary-level, and two primary-level hospitals) in Pudong New Areas of Shanghai, based on location, catchment areas and number of patients. All recruited outpatients were interviewed in hospitals, using a standard questionnaire. Stool specimens were collected and tested for five viral and eight bacterial pathogens.Results:A total of 9 301 cases with infectious diarrhea were included, and the overall positive rate was 55.7 % (5 179). Positive rates of single virus, single bacteria and mixed infections were 26.7 % (2 481), 17.0 % (1 579) and 12.0 % (1 119), respectively. For single infection, the most commonly detected viruses appeared as norovirus (15.4 %, 1 428/9 301) and rotavirus (7.2 %, 667/9 301). The most commonly detected bacteria were diarrheagenic Escherichia coli (6.7 %, 619/9 301) and non-typhoid Salmonella (3.3 %, 305/9 301). The most common mixed infections were caused by virus-bacteria (4.9 %, 459/9 301). Norovirus (17.0 %, 838/4 938) showed the highest positive rates, followed by Escherichia coli (7.2 %, 354/4 938), both seen in the age group of 20-59 years old group. Rotavirus (9.4 %, 178/1 896) and non-typhoid Salmonella (4.9 %, 93/1 896) were the most common pathogens found in the age group of 0-4 years old. The prevalence of norovirus peaked both in spring and autumn. The other peaks were seen as: Rotavirus in winter, diarrheagenic Escherichia coli in summer and non-typhoid Salmonella in summer. Conclusions:Our data showed that the positive rates of infectious diarrhea pathogens were high in Pudong New Areas of Shanghai from 2013 to 2017. The dominant pathogens would include norovirus, rotavirus and diarrheagenic Escherichia coli but with differenct distributions in age groups. Obvious seasonal patterns were also observed.

Objective To analyze the survival and toxicity after concurrent chemoradiotherapy in patients of different ages with stage Ⅳ non-small cell lung cancer (NSCLC).Methods Clinical data of 282 NSCLC patients in two prospective studies were retrospectively analyzed,who completed the protocol (at least 2 cycles of chemotherapy and thoracic radiation doses of ≥36 Gy).Among them,44 patients were assigned into in the young group (≤ 45 years old),161 patients in the middle-age group (46-64 years old) and 77 patients in the elderly group (≥ 65 years old).The clinical characteristics of patients among different groups were analyzed by x2 test.The overall survival (OS) was calculated by Kaplan-Meier method.Stratified analysis was performed by Log-rank test.Multi-factor prognosis analysis was conducted by Cox's proportional hazards regression model.Results The incidence of NSCLC in the male patients in the elderly group was higher than that in the middle-age and young groups.The 1-,2-,3-and 5-year OS did not significantly differ among different groups (P=0.810).The OS did not significantly differ among patients of the same gender,pathological type,T stage,N stage,metastasis status,same chemotherapy cycle,primary tumor dose and comprehensive treatment and short-term response (all P＞0.05).The incidence of adverse events did not considerably differ among different groups.Multivariate analysis demonstrated that age was not an independent factor for survival (P＞ O.05).Conclusion Patients of different ages with stage Ⅳ NSCLC obtain similar survival benefits and adverse events after concurrent chemoradiotherapy.
