Objective: To investigate the self-monitoring blood pressure behavior and its influencing factors among residents in Jiangsu Province, so as to provide the basis for strengthening proactive blood pressure monitoring among residents. Methods: Permanent residents aged 35-75 years in six counties (cities, districts), Jiangsu Province, were selected using the stratified cluster sampling method in 2023. Data on basic information, disease history, and self-monitoring blood pressure behavior were collected, height and weight were measured to calculate the body mass index (BMI); and blood glucose and lipid levels were measured. Self-monitoring blood pressure behavior was defined as having measured blood pressure at least once in the past three months. Factors affecting self-monitoring blood pressure behavior were identified using a multivariable logistic regression model. Results: A total of 12 475 residents were surveyed, including 5 748 males and 6 727 females, with a male-to-female ratio of 1∶1.17. There were 3 855 residents aged 45-<55 years (30.90%) and 5 511 residents who had self-monitoring blood pressure behaviors (44.18%). Multivariable logistic regression analysis showed that the residents who were males (OR=1.167, 95%CI: 1.081-1.261), lived in rural areas (OR=1.430, 95%CI: 1.321-1.547), aged 45-75 years (45-<55 years, OR=1.384, 95%CI: 1.241-1.543; 55-<65 years, OR=1.397, 95%CI: 1.243-1.570; 65-75 years, OR=1.196, 95%CI: 1.049-1.363), had an annual household income ≥30 000 yuan (30 000-<60 000 yuan, OR=1.190, 95%CI: 1.072-1.321; 60 000-<110 000 yuan, OR=1.330, 95%CI: 1.191-1.485; ≥110 000 yuan, OR=1.746, 95%CI: 1.536-1.984), were overweight (OR=1.170, 95%CI: 1.070-1.280) or obese (OR=1.248, 95%CI: 1.120-1.391), were unaware (OR=1.221, 95%CI: 1.103-1.353) or aware (OR=3.937, 95%CI: 3.575-4.335) of having hypertension, were aware of having diabetes (OR=1.538, 95%CI: 1.354-1.749), and aware of having dyslipidemia (OR=1.265, 95%CI: 1.106-1.447) were more likely to have self-monitoring blood pressure behaviors. Conclusions Among the residents aged 35-75 years in Jiangsu Province, 44.18% had self-monitoring blood pressure behavior. Gender, place of residence, age, annual household income, BMI, hypertension, diabetes, and dyslipidemia were identified as influencing factors for self-monitoring blood pressure behavior.

OBJECTIVES: To characterize fine particulate matter (PM _2.5)-bound polycyclic aromatic hydrocarbons (PAHs) emitted from different cooking fumes and their exposure routes and assess their health-associated impact to provide a reference for health risk prevention from PAH exposure across different age and sex groups. METHODS: Sixteen PM _2.5-bound PAHs emitted from 11 cooking styles were analyzed using GC-MS/MS. The health hazards of these PAHs in the Handan City population (stratified by age and sex) were predicted using the incremental lifetime cancer risk ( ILCR) model. The respiratory deposition doses ( RDDs) of the PAHs in children and adults were calculated using the PM _2.5 deposition rates in the upper airway, tracheobronchial, and alveolar regions. RESULTS: The total concentrations of PM _2.5-bound PAHs ranged from 61.10 to 403.80 ng/m ³. Regardless of cooking styles, the ILCR _total values for adults (1.23 × 10 ^-6 to 3.70 × 10 ^-6) and older adults (1.28 × 10 ^-6 to 3.88 × 10 ^-6) exceeded the acceptable limit of 1.00 × 10 ^-6. With increasing age, the ILCR _total value first declined and then increased, varying substantially among the population groups. Cancer risk exhibited particularly high sensitivity to short exposure to barbecue-derived PAHs under equivalent body weights. Furthermore, barbecue, Sichuan and Hunan cuisine, Chinese cuisine, and Chinese fast food were associated with higher RDDs for both adults and children. CONCLUSION ILCR _total values exceeded the acceptable limit for both females and males of adults, with all cooking styles showing a potentially high cancer risk. Our findings serve as an important reference for refining regulatory strategies related to catering emissions and mitigating health risks associated with cooking styles.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective To establish the therapeutic effect prediction model of platelet transfusion in hematological patients,and receiver operating characteristic(ROC)curve and clinical cases are used to evaluate the clinical application value of the predic-tion model.Methods A total of 485 patients with hematological diseases who received platelet transfusion therapy in Kailuan General Hospital from January 2020 to December 2023 were selected,corrected count increment(CCI)was used to divide the patients into platelet transfusion effective group(n=340)and transfusion ineffective group(n=145).Multivariate Logistic regres-sion analysis was used to establish the prediction model of platelet infusion efficacy,and ROC curve was used to evaluate the application effect of the forcasting model.109 clinical cases were used to verify the practical application effect of the model,and the sensitivity,specificity and accuracy were calculated.Results Among 485 patients with hematological diseases,the incidence of ineffective platelet transfusion was 29.90%(145/485).Compated with the effective group,the ineffective group had more previous platelet transfusions was higher,and the difference was statistically significant(t=-4.435,P<0.05).In the ineffective group,there were more cases of hyperplenism,aplastic anemia and lymphoma,higher infection rate and higher positive rate of platelet antibody,and the differences were statistically significant(χ2=6.301～37.522,all P<0.05).Multivariate Logistic regres-sion analysis found that previous platelet infusion times,infection,leukemia,aplastic anemia and platelet antibodies were risk factors for ineffective platelet transfusion in patients with hematological diseases(Wald χ2=5.224～21.548,all P<0.05).Based on these risk factors,platelet infusion effect prediction models 1 and 2 were constructed.ROC curve was used to evaluate the application effect of the prediction model.The area under the curve(AUC),cut-offpoint,sensitivity and specificity of model 1 were 0.884,0.042,82.35%,88.89%.The AUC,cut-offpoint,corresponding sensitivity and specificity of prediction model 2 were 0.910,59.784,81.18%,94.44%,respectively.The Z values of model 1 and model 2 were 12.159 and 13.151,respectively.The prediction effect of model 2 was better than that of model 1.The actual application results showed that the sensitivity,specificity and accuracy of prediction model 1,2 were 85.71%,92.05%,90.89%and 90.48%,93.18%,92.66%,respectively.Conclusion The ineffective rate of platelet transfusion in hematological patients is relatively high.The prediction models 1 and 2 for platelet transfusion effectiveness have good results in predicting ineffective platelet transfusion,and prediction model 2 is better than pre-diction model 1,which can provide reliable basis for hematological patients on accurate platelet transfusion.

Objective To explore the preventive and therapeutic effects of Caryopteris incana decoction in a rat model of primary dysmenorrhea with cold coagulation and blood stasis syndrome.Methods Sixty healthy specific pathogen-free SD female rats were randomly divided into six groups of ten rats each:normal group,model group,ibuprofen group,C.incana high-dose group,C.incana medium-dose group,and C.incana low-dose group.All groups except the normal group were treated with cold stimulation combined with estradiol benzoate and oxytocin to establish a rat model of primary dysmenorrhea with cold coagulation and blood stasis syndrome.On the fifth day of modeling,the rats were intragastrically administered the study drugs for 10 days.Their symptoms were observed and recorded.The writhing response and hemorheological indices were measured.The serum levels of TXB2,6-keto-prostaglandin F1α(6-Keto-PGF1α),estradiol(E2),and progesterone(PROG)were measured.Additionally,the levels of prostaglandin F2α(PGF2α),prostaglandin E2(PGE2),nitric oxide(NO),and calcium(Ca2+)in the uterine tissues were measured.The organ indices of the uterus and ovary were calculated,and histopathological changes were observed.Results Compared with the normal group,the rats in the model group showed obvious symptoms of cold coagulation and blood stasis syndrome and writhing reaction.The morphology of uterus and ovary showed obvious hyperplasia,inflammation,edema and other lesions.The plasma viscosity,packed cell volume and whole blood viscosity were significantly increased(P＜0.01).The serum levels of thromboxane B2 and E2 and the E2/PROG ratio were significantly increased(P＜0.01),the levels of 6-Keto-PGF1α and PROG were significantly decreased(P＜0.01).The uterine index and ovarian index were significantly increased(P＜0.01).The levels of PGF2α and Ca2+and the PGF2α/PGE2 ratio in uterine tissue were significantly increased(P＜0.01),while the levels of PGE2 and NO were significantly decreased(P＜0.01).Compared with the model group,Caryopteris incana significantly improved the symptoms of model rats,improved the morphological lesions of the uterus and ovary,prolonged the latency time of the writhing reaction,and reduced the number of writhing episodes(P＜0.01);significantly reduced the plasma viscosity,packed cell volume,and whole blood viscosity(P＜0.01);significantly reduced the serum levels of TXB2 and E2 and the E2/PROG ratio,increased the serum levels of 6-Keto-PGF1αand PROG,and reduced the uterine and ovarian indices(P＜0.01,P＜0.05);significantly reduced the levels of PGF2αand Ca2+and the PGF2α/PGE2 ratio in uterine tissue(P＜0.01,P＜0.05);and significantly increased the levels of PGE2 and NO in the uterine tissue(P＜0.01).Conclusions Caryopteris incana decoction can effectively improve the clinical symptoms of primary dysmenorrhea in rats with cold coagulation and blood stasis syndrome,and it has a good control effect.Its mechanism may be correlated with the levels of TXB2,6-Keto-PGF1α,E2,and PROG in serum and PGF2α,PGE2,NO,and Ca2+in uterine tissue.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

AIM To study the protective effects and mechanism of pueraria isoflavones on myocardial injury in ovariectomized rats.METHODS Thirty-six rats were randomly divided into the sham operation group,the model group,the estradiol valerate group(0.1 mg/kg)and the low,medium and high dose pueraria isoflavones groups(55,110,220 mg/kg).In contrast to the rats of the sham operation group having their small pieces of adipose tissue removal around the ovaries,rats of the other groups had their bilateral ovaries excised,followed by the 16-week corresponding oral drug administration 2 weeks later at a once daily frequency for,6 days a week.At the end of the 16th week,the rats had their hemodynamics[systolic pressure(SBP),diastolic pressure(DBP),mean pressure(MBP),left ventricular systolic pressure(LVSP),left ventricular diastolic pressure(LVMP),and the maximum rate of increase and decrease of left ventricular pressure during isovolumic contraction(±dp/dtmax)]detected by PowerLab;their cardiac pathological changes observed by HE staining;their levels of creatine kinase(CK),lactate dehydrogenase(LDH),total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)and glucose(Glu)in plasma detected by biochemical analyzer;their myocardial level of adenosine triphosphate(ATP)detected by colorimetry;their mRNA expressions of glucose transporter 4(GLUT4),lactate dehydrogenase A(LDHA),carnitine palmitoyl transferase-1(CPT-1α),acyl coenzyme A carboxylase(ACC),liver kinase B1(LKB1),adenylate-activated protein kinase(AMPK)and peroxisome proliferator-activated receptor γ coactivator factor 1α(PGC-1α)detected by RT-qPCR;and their myocardial expressions of energy metabolism related proteins LKB1,p-AMPK/AMPK and PGC-1α detected by Western blot.RESULTS Compared with the model group,the pueraria isoflavones groups displayed decreased levels of SBP,DBP,MBP,LVSP,LVMP(P＜0.05,P＜0.01);increased-dp/dtmax(P＜0.05,P＜0.01);improved myocardial fibrinolysis,gap widening and inflammatory infiltration caused by ovariectomy;decreased activities of LDH and CK(P＜0.05);increased myocardial ATP level(P＜0.05,P＜0.01);decreased levels of TC,TG,LDL-C and Glu(P＜0.05,P＜0.01);increased HDL-C level(P＜0.05,P＜0.01);increased myocardial mRNA expressions of GLUT4,LDHA,CPT-1α,ACC,LKB1,AMPK and PGC-1α(P＜0.05,P＜0.01);and increased protein expressions of myocardial LKB1,p-AMPK/AMPK and PGC-1α(P＜0.05,P＜0.01).CONCLUSION Pueraria isoflavones are protective to myocardial injury in ovariectomized rats,and the mechanism may lie in the improvement of energy metabolism-related myocardial proteins via LKB1/AMPK/PGC-1α signaling pathway.

ObjectiveTo introduce the basic design， development plan and objectives of a population-based birth cohort in Shanghai， and further present the main data and baseline characteristics of enrolled participants in the cohort， and to provide key information for reproductive health-related studies. MethodsThe Shanghai population-based birth cohort initiated on January 1， 2005， included newborns born in Shanghai every year and their parents， and collected information on reproductive health， reproductive treatment， birth characteristics， growth and development status， as well as the incidence， treatment and death of diseases by employing data linkage technology and investigations. This formed a birth cohort spanning the entire life cycle. ResultsAs of October 2022， a total of 2 978 538 newborns and their parents were included in the cohort. Among them， 2 905 135 （97.54%） were naturally conceived （NC）， and 73 403 （2.46%） were born through assisted reproductive technologies （ART）. The average age of parents was （32.56±4.12） years old for females and （34.62±5.34） years old for males in the ART group， which was higher than （28.02±4.71） years and （30.07±5.54） years for parents in the NC group. Among parents， females and males aged 30 and above accounted for 77.12% and 85.08%， respectively， which were higher than that of parents （35.28% for females and 49.66% for males） in the NC group. Furthermore， the percentage of parents with a college degree or above in the ART group was 73.23% for females and 73.66% for males， which were higher than those in the NC group （49.98% and 50.91%， respectively）. The multiple births rate in the ART group was 33.81%， which was higher than that in the NC group （1.88%）. The incidence of premature birth and low birth weight in the ART group were 24.47% and 19.08%， respectively， which was higher than that in the NC group （5.47% and 3.73%）. ConclusionThe comprehensive collection of reproductive health-related information in the birth cohort in Shanghai can provide essential resources to determine the influence of genetics， environment， reproductive treatment and other related factors on the health of offspring after birth.
