The rapid development of the pharmaceutical research and development (R&D) has brought new challenges to occupational health management, including the high uncertainty in the R&D process, emerging hazards, and compliance complexities associated with novel business models. Traditional management approaches exhibit limitations in effectively addressing the occupational health risks associated with these challenges. Based on the perspective of agile governance, this paper proposed an optimized pathway characterized by dynamic response, adaptive flexibility, and multi-stakeholder collaboration. It further offered countermeasures and recommendations from three aspects: concept renewal, mechanism innovation, and tool empowerment, aiming to provide reference for the effective management and control of occupational health risks in the innovation and development of the pharmaceutical R&D industry.

Objective To investigate clinical effect of tendons pulling,poking and kneading for the treatment of external humeral epicondylitis.Metods From January 2018 to December 2021,a multicenter randomized controlled study was per-formed to collect 192 patients with external humeral epicondylitis in Wangjing Hospital,Beijing Dianli Hospital,and Beijing Fengsheng Osteotraumatology Hospital,respectively,and they were divided into treatment group and control group by random number table method.There were 96 patients in treatment group,including 36 males and 60 females,aged from 28 to 60 years old with an average of(41.20±5.50)years old;the course of disease ranged from 1 to 14 days with an average of(5.24±1.35)days;they were treated once every other day for 2 weeks.There were 96 patients in control group,including 33 males and 63 females,aged from 26 to 60 years old with an average of(43.35±7.75)years old;the course of disease ranged from 1 to 14 days with an average of(5.86±1.48)days;they were treated with topical voltaalin combined with elbow joint fixation for 2 weeks.Visual analogue scale(VAS)and Hospital for Surgery Scoring System(HSS)elbow pronation and supination angles,wrist metacarpal flexion and dorsal extension angles,elbow tenderness between two groups were compared before treatment and at 1,3,5,7,11 and 13 days after treatment;Hospital for Surgery Scoring System 2(HSS2)was compared before treatment and the final treatment.Results All patients were followed up for 10 to 14 days with an average of(12±1.6)days.VAS between treatment group and control group before treatment were 6.83±1.36 and 6.79±1.58,respectively,and decreased to 1.49±1.09 and 2.11±1.81 after the final treatment.VAS of treatment group were significantly lower than those of control group at 1,3,5,7,9,11 and 13 days after treatment(P＜0.05).HSS between two groups were 61.73±11.00 and 36.47±12.45 before treatment,respectively,and increased to 94.42±5.9 and 91.44±9.11 at the final treatment.HSS of treatment group were signifi-cantly higher than those of control group at 1,3,5,7,9,11 and 13 days after treatment(P＜0.05).On the 5th day after treat-ment,the external and internal rotation angles of elbow in treatment group were(66.41±12.69)° and(66.35±13.54)°,while those in control group were(62.08±16.03)° and(61.77±16.35)°.On the 7th day after treatment,the external and internal ro-tation angles of elbow were(69.79±12.64)° and(70.02±13.55)° in treatment group,and(65.28±15.86)° and(65.09± 16.67)° in control group.Elbow joint motion in treatment group was higher than that in control group(P＜0.05).On the 5th day after treatment,angles of wrist dorsiflexion and palm flexion were(39.43±15.94)°and(46.68±11.10)° in treatment group,and(38.51±18.49)° and(44.27±13.58)° in control group.On the 7th day after treatment,angles of wrist dorsiflexion and palm flexion were(42.52±16.50)° and(49.23±10.96)° in treatment group,and(41.18±20.09)° and(46.64±14.63)° in control group.The motion of wrist joint in treatment group was higher than that in control group(P＜0.05).On the 13th day after treatment,HSS2 in treatment group 93.61±6.32 were higher than those in control group 92.06±7.94(P＜0.05).There was no significant difference in elbow tenderness between two groups at each time point(P＞0.05).Conclusion Voltaren external treatment combined with elbow fixation and tendons pulling,poking and kneading could effectively improve symptoms of exter-nal humeral epicondylitis.Compared with voltaren external treatment,tendons pulling,poking and kneading has advantages of longer analgesic time and better elbow function recovery.

Objective:To investigate the relationship between walking speed, life-space mobility (LSM), cognitive function and mild cognitive impairment (MCI) in elderly patients with type 2 diabetes mellitus in community, and compare the predictive value of walking speed and LSM alone and combined in elderly patients with type 2 diabetes mellitus.Methods:This was a cross-sectional study. Using the convenient sampling method, a total of 448 elderly patients with type 2 diabetes mellitus from three communities in Hefei City were selected as the research objects from September 2022 to May 2023. Daily walking speed was measured using the 4-Meter Walking Speed, LSM was assessed using the Chinese version of Life-Space Assessment (LSA), and cognitive function was evaluated using the Chinese version of Montreal Cognitive Assessment (MoCA). Participants were divided to the MCI group and non-MCI group. Spearman correlation analysis was used to explore the relationships between walking speed, LSM and cognitive function. Logistic regression analysis was used to analyze the relationship between walking speed, LSM and MCI. Area under the curve ( AUC) of receiver operating characteristic (ROC) curve analysis was performed to compare the effects of walking speed and Chinese version LSA score on the prediction of MCI alone and in combination. Results:The walking speed and the Chinese version LSA score were both positively correlated with the Chinese version MoCA score ( r=0.598, 0.543; P<0.05). Chinese version LSA score ( OR=0.942) and walking speed score ( OR=0.490) were influencing factors for MCI in elderly patients with type 2 diabetes mellitus ( P<0.05). The AUC for walking speed in predicting MCI was 0.875, with a cutoff value of 3 points. Chinese version LSA score in predicting MCI had an AUC of 0.887 with a cutoff value of 59 points. When used in combination, they achieved an AUC of 0.915, with cutoff values of 55 points for Chinese version LSA scores and 3 points for walking speed scores. Conclusions:The combination of walking speed and LSM can more accurately predict the occurrence of MCI in elderly patients with type 2 diabetes mellitus than the single application, which provide a reference for improving the cognitive function of elderly patients with type 2 diabetes mellitus.

Objective:To explore the chain mediating effect of self-rated health and aging attitudes on the relationship between life space and psychological distress of community-dwelling older adults.Methods:From August to November 2023, convenience sampling was used to select older adults from three communities of Baohe District in Hefei City as subjects. General Information Questionnaire, Life Space Assessment (LSA), Self-Rated Health (SRH), Attitudes to Aging Questionnaire (AAQ), and 10-item Kessler Psychological Distress Scale (K10) were used for the survey. Spearman correlation was used to analyze the correlation between life space and self-rated health, aging attitudes, and psychological distress. Process macro program of SPSS 25.0 software was used to test for mediating effects.Results:A total of 700 questionnaires were distributed and 669 valid questionnaires were collected, with a valid response rate of 95.57%. Among 669 community-dwelling older adults, the LSA, SRH, AAQ, and K10 scores were (74.35±19.39), (3.23±0.96), (80.66±13.43), and (19.29±6.26), respectively. Spearman correlation analysis showed a positive correlation between life space and attitudes to aging ( rs=0.568, P<0.01) and negative correlations between life space and self-rated health and psychological distress ( rs=-0.334 and -0.455; both P<0.01). The mediating effect test showed that self-rated health and aging attitudes had chain mediating effects on life space and psychological distress, with a mediating effect value of -0.053, accounting for 11.60% of the total effect. Conclusions:Life space can not only directly affect the psychological distress of community-dwelling older adults but also indirectly predict psychological distress through the mediating effect of self-rated health and aging attitudes.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-positive bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-positive bacteria from blood cultures in member hospitals of National Bloodstream Infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:A total of 3 163 strains of Gram-positive pathogens were collected from 51 member units，and the top five bacteria were Staphylococcus aureus（ n=1 147，36.3%），coagulase-negative Staphylococci（ n=928，29.3%）， Enterococcus faecalis（ n=369，11.7%）， Enterococcus faecium（ n=296，9.4%）and alpha-hemolyticus Streptococci（ n=192，6.1%）. The detection rates of methicillin-resistant Staphylococcus aureus（MRSA）and methicillin-resistant coagulase-negative Staphylococci（MRCNS）were 26.4%（303/1 147）and 66.7%（619/928），respectively. No glycopeptide and daptomycin-resistant Staphylococci were detected. The sensitivity rates of Staphylococcus aureus to cefpirome，rifampin，compound sulfamethoxazole，linezolid，minocycline and tigecycline were all >95.0%. Enterococcus faecium was more prevalent than Enterococcus faecalis. The resistance rates of Enterococcus faecium to vancomycin and teicoplanin were both 0.5%（2/369），and no vancomycin-resistant Enterococcus faecium was detected. The detection rate of MRSA in southern China was significantly lower than that in other regions（ χ2=14.578， P=0.002），while the detection rate of MRCNS in northern China was significantly higher than that in other regions（ χ2=15.195， P=0.002）. The detection rates of MRSA and MRCNS in provincial hospitals were higher than those in municipal hospitals（ χ2=13.519 and 12.136， P<0.001）. The detection rates of MRSA and MRCNS in economically more advanced regions（per capita GDP≥92 059 Yuan in 2022）were higher than those in economically less advanced regions（per capita GDP<92 059 Yuan）（ χ2=9.969 and 7.606， P=0.002和0.006）. Conclusions:Among the Gram-positive pathogens causing bloodstream infections in China， Staphylococci is the most common while the MRSA incidence decreases continuously with time；the detection rate of Enterococcus faecium exceeds that of Enterococcus faecalis. The overall prevalence of vancomycin-resistant Enterococci is still at a low level. The composition ratio of Gram-positive pathogens and resistant profiles varies slightly across regions of China，with the prevalence of MRSA and MRCNS being more pronounced in provincial hospitals and areas with a per capita GDP≥92 059 yuan.

Objective:To investigate the diagnostic value of serum matrix metalloproteinase 3 (MMP-3) combined with anti-mutant citrulline vimentin antibody (anti-MCV) and rheumatoid factor (RF) in rheumatoid arthritis (RA).Methods:A retrospective study was conducted to select 78 patients diagnosed with RA, 30 with Sjogren′s syndrome (SS), 25 with connective tissue disease (CTD), and 38 with antiphospholipid syndrome (APS) from the Nanjing Drum Tower Hospital Clinical College of Nanjing Medical University from August 2022 to April 2024. In the same period, 50 healthy controls were selected from the physical examination center of our hospital. Fasting peripheral blood RF, anti-streptolysin O (ASO), C-reactive protein (CRP), erythrocyte deposition rate (ESR), interleukin-6 (IL-6), procalcitonin (PCT), anti-keratin antibody (AKA), anti-MCV, MMP-3, anti-cyclic citrullinated peptide (anti-CCP) level. Fasting peripheral blood MMP-3 levels in SS, CTD, APS patients and healthy control group were compared, Spearman correlation analysis was used to evaluate the correlation between MMP-3 levels and various indicators, and logistic regression analysis was used to screen the related influencing factors of RA occurrence. The diagnostic value of serum MMP-3, anti-MCV, RF and combined detection for RA was evaluated by receiver operating characteristic (ROC) curve.Results:There were statistically significant differences in RF, CRP, ESR, IL6, AKA, antiMCV, MMP-3 and anti-CCP between RA group and healthy control group (all P<0.001), while there were no statistically significant differences in PCT and ASO between the RA group and the healthy control group (all P>0.05). Serum MMP-3 level in the RA group was significantly higher than that in SS, CTD, APS and healthy control group, and the difference was statistically significant (all P<0.05). MMP-3 was positively correlated with anti-CCP, CRP, ESR, anti-MCV, RF and AKA ( r=0.403, 0.532, 0.530, 0.431, 0.427, 0.391, all P<0.05). Multivariate logistic regression analysis showed that MMP-3 ( OR=1.082, P=0.02), anti-MCV ( OR=1.015, P=0.049) and RF ( OR=1.046, P=0.036) were independent risk factors for RA. ROC curve showed that when the cut-off value of MMP-3 was 53.10 ng/ml, the area under the curve for diagnosing RA was 0.889, the sensitivity was 74.5%, and the specificity was 96.0%. The area under ROC curve of MMP-3 combined with anti-MCV and RF for the diagnosis of RA was 0.975, the sensitivity was 88.2%, and the specificity was 99.7%. Conclusions:MMP-3 has a certain value in the differential diagnosis of RA, and MMP-3 combined with anti-MCV and RF is of great significance in the auxiliary diagnosis of RA.
