OBJECTIVE To explore the effects of multi-disciplinary comprehensive management team of tertiary hospital collaborated with the pharmacists from community health service center （hereinafter referred to as “community pharmacists”） on elderly patients with hypertension in the community. METHODS Elderly patients with hypertension from May 2020 to May 2021 in Yuhua Community Health Service Center of Nanjing were divided into control group （76 cases） and observation group （76 cases） according to the management style. The control group was treated with regular community medical services and the observation group received regular community medical services plus pharmaceutical care provided by the comprehensive management team collaborated with community pharmacists. The compliance， blood pressure control status and hypertension-related complications were compared between 2 groups before management and after 24 months of management. RESULTS After 24 months of management， the compliance and blood pressure compliance rates in both groups were higher than before management； meanwhile， the observation group was significantly higher than control group at the corresponding period （P＜0.05 or P＜ 0.01）. The blood pressure levels of both groups were significantly lower than before management， and the systolic blood pressure as well as the incidences of the whole complications and cerebrovascular injury in the observation group were significantly lower than control group at the 583867635@qq.com corresponding period （P＜0.05）. There was statistical significance in the effects of the rate of reaching the standard of blood pressure on the complications （P＜0.01）. CONCLUSIONS The hypertension management mode of comprehensive management team collaborated with community pharmacists can significantly improve the compliance and blood pressure compliance rate of elderly patients with hypertension， and reduce the incidence of hypertension-related complications.

Consciousness and unconsciousness represent a compelling topic in psychology and neuroscience, embodying a dynamic interplay between two fundamental cognitive states. Understanding the cognitive and neural mechanisms underlying their interaction poses a significant challenge. While previous studies have predominantly focused on the impact of attention on consciousness, the influence of attention on unconscious processes has often been overlooked. However, the role of attention in modulating unconscious information processing is paramount, as it can regulate various aspects of unconscious visual processing, including simple visual information, semantic content, and emotional stimuli. Within the visual processing pathway, attention operates at early levels to modulate unconscious visual processing, starting at least from the eye-of-origin and visual orientations. In the semantic system, attention can top-down enhance unconscious semantic processes in a goal-dependent manner, enhancing goal-relevant processes while suppressing goal-irrelevant ones. In the emotional system, attentional load, in addition to target relevance, can regulate unconscious emotional processing. These findings suggest that the regulatory role of attention on unconscious processes depends on both goal relevance and the amount of attentional resources. Specifically, the goal-relevance of unconscious processes determines the direction of attentional modulation, while the amount of attentional resources allocated determines the extent of modulation. The once-prevailing notion that unconscious processing is automatic and not subject to attentional modulation has been gradually overturned. Current studies indicate that attention can modulate both conscious and unconscious processes, providing a new perspective on the relationship between attention and consciousness. Spatial attention can operate independently from consciousness at the neural representation level. Furthermore, other factors tightly related to attention, such as goal-related task sets, working memory, and attentional load, can all impact unconscious processes. These findings collectively suggest that attention and consciousness are functionally dissociated, supporting the idea that attention is necessary for both conscious and some unconscious processes. In conclusion, unconscious information processing is a complex and intriguing field where attention plays a crucial role. Continued in-depth research in this area is needed to deepen our understanding of how the human brain processes unconscious information and how attention exerts its regulatory influence. This not only requires studying the commonalities and specificities of different types of attention but also examining the sharing and individuality among different sensory modalities and cognitive modules. Theoretically, this not only helps us understand the mechanisms of attention but also sheds light on the mechanisms of consciousness. Studying these issues is also of practical value. Importantly, the organization and regulation of unconscious processes are closely related to human survival and development. For example, while rapid unconscious emotional processes (such as unconscious fear) are beneficial for rapid threat responses and increased survival chances, excessive and uncontrolled unconscious emotional processes can lead to anxiety disorders, phobias, and other mental disorders. Furthermore, while repeated perceptual and behavioral training can improve efficiency by forming highly automated unconscious processes, excessively stubborn unconscious processes can hinder the learning of new skills. Studying the role of attention in regulating these unconscious processes can help develop new intervention methods to maintain mental health and improve behavioral performance.

Objective To investigate the current situation and health effects of indoor microbial pollution in Xi'an, to analyze the purification effect of air purifiers on indoor microbial pollution, and to provide reference for improving the indoor environment. Methods Through stratified random sampling, 20 families from rural areas and 20 families from upwind and downwind urban areas respectively were selected from Xi'an. Data was collected by questionnaire surveys and on-site environmental sampling. Non-parametric analysis and correlation analysis were used for statistical analysis. Results Overall, the standard-exceeding rate of total count of bacteria was 5.00%. The medians of the total count of bacteria and fungi were 312.50 cfu/m3 and 260.00 cfu/m³, respectively. In terms of health effects, the correlation between rhinitis and cold with total bacterial count was statistically significant (P<0.05), with the correlation coefficients of 0.182 and 0.223, respectively. Purification effect of air purifiers on microbial pollution was statistically significant (P<0.05). After opening for 2 hours, the total numbers of bacteria and fungi decreased significantly. Conclusion The occurrence risk of colds and rhinitis is increased by indoor microbial pollution. Air purifiers have a certain effect on decreasing the total number of bacteria and fungi. It is recommended to use air purifiers with high CADR of particulate matter, double-layer filter and sterilization and dehumidification function, and replace the filters regularly to reduce indoor microbiological contamination.

Breast cancer is the most diagnosed cancer in women worldwide and the leading cause of most cancer-related deaths,posing a serious threat to women′s health worldwide.At present,although the prognosis of some patients with breast cancer has improved,the emergence of drug resistance and the metastasis and recurrence of breast cancer are still the main reasons for poor prognosis.CD36 is a multiligand transmembrane glycoprotein expressed on various cell types.In recent years,studies have confirmed that CD36 can reshape the lipid metabolism of cancer cells;promote the differentiation of tumor-related macrophages into M2 type and recruitment into tumor tissues;regulate the function of Treg cells,CD8+T cells,DCs,and other immune cells,and thus promote tumor development.In addition,CD36 is also associated with breast cancer stem cells,metastasis-initiating cells,and breast drug resistant cells.Therefore,CD36 could be an important potential therapeutic target for breast cancer.

Objective:To investigate which indicator is more advantageous when using arterial oxygen saturation(SaO2)and fingertip pulse oxygen saturation(SpO2)for blood oxygen detection in patients with hyperleukocytic acute leukemia(HAL).Methods:In this prospective research,the difference between SaO2 and SpO2 of 18 HAL patients(observation group)and 14 patients(control group),as well as the relationship between the difference and white blood cell(WBC)counts were analyzed.Results:SaO2 was lower than SpO2 in the observation group(P＜0.05),and SpO2-SaO2 difference was positively correlated with WBC counts(r=0.47).However,there was no statistical difference between SaO2 and SpO2 in the control group.SaO2 and PO2 showed a downward trend with the prolongation of detection time after arterial blood was collected in the observation group,but there was no statistical difference.There was no downward trend of SaO2 and PO2 in the control group.Conclusion:HAL patients have a phenomenon where SaO2 is lower than SpO2,that is pseudohypoxemia,and this phenomenon may be caused by excessive consumption of oxygen by the leukemia cells in vitro.SpO2 can be monitored bedside in real time and is non-invasive,it is a better way to detect the blood oxygen status of HAL patients.

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.

Objective:To analyze clinical efficacy, failure mode and prognostic factors of nasopharyngeal carcinoma (NPC) patients undergoing intensity modulated radiation therapy (IMRT).Methods:Clinical data of 951 locally advanced NPC patients who were newly-treated with IMRT in Hunan Cancer Hospital from January 2018 to January 2019 were retrospectively analyzed. The patients' general data, overall survival (OS), local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), local recurrence-free survival (LRRFS), distant metastasis-free survival (DMFS), and progression-free survival (PFS) were analyzed. Comparison among different groups was performed by one-way ANOVA. Survival rate was calculated by Kaplan-Meier method. Survival difference was compared by log-rank test. Univariate and multivariate analyses were performed by Cox regression model.Results:The median follow-up time was 62.0 months (IQR, 58.0-65.0 months). The 5-year OS, LRFS, RRFS, LRRFS, DMFS, and PFS were 85.4%, 94.0%, 97.7%, 92.6%, 85.7% and 76.9%, respectively. According to the 8th edition staging of American Joint Committee on Cancer (AJCC), there were 10 cases (1.1%) of stage I, 76 cases (8.0%) of stage II, 445 cases (46.8%) of stage III, and 420 cases (44.2%) of stage IVA, respectively. Among them, the OS rates of stage I, II, III and IVA patients were 100%, 97.2%, 88.8% and 79.2%, respectively ( P<0.001); LRRFS rates were 100%, 90.4%, 94.7% and 90.4%, respectively( P=0.104); DMFS rates were 90.0%, 95.9%, 88.0% and 81.1%, respectively ( P<0.001); PFS rates were 90.0%, 89.1%, 80.9% and 70.1% respectively ( P<0.001). There were 183 cases of treatment failure, including 52 cases (5.5%) of local failure, 19 cases (2.0%) of regional failure, 130 cases (13.7%) of distant metastasis, 16 cases of local combined with regional failure (1.7%), 16 cases (1.7%) of local failure combined with distant metastasis, 13 cases (1.4%) of regional failure combined with distant metastasis, and 9 cases (0.9%) of local regional failure combined with distant metastasis, respectively. Multivariate regression analysis suggested that EB virus DNA copy number before treatment, T stage and N stage were the independent prognostic factors affecting OS, DMFS and PFS. Conclusions:Compared with two-dimensional radiotherapy, IMRT has improved the overall therapeutic effect for NPC, especially the local control rate. Distant metastasis is still the main failure mode. Clinical staging, prognostic risk stratification and prognostic biomarkers can be combined to deliver stratified and precise treatment, which may further improve clinical efficacy and reduce treatment-related side effects.

Objective To construct a non-drug intervention program for acute chemotherapy-related nausea and vomiting in children with cancer and to evaluate its efficacy.Methods Through literature review and Delphi expert correspondence,a non-drug intervention program for acute chemotherapy-related nausea and vomiting in children with cancer was constructed.By the convenience sampling method,200 consecutive children who received chemotherapy in the neurosurgery department of a tertiary children's hospital in Zhejiang province from February 1 to October 31,2023 were included as the application subjects,with 100 cases in an experimental group and 100 cases in a control group.The experimental group applied the non-drug intervention program of acute chemotherapy-related nausea and vomiting in children with cancer,and the routine measures were applied in the control group.The incidence of nausea and vomiting,severity of vomiting,compliance rate of normal sleep duration and incidence of negative emotions were compared between the 2 groups.Results The recovery rate of the valid questionnaire in 2 rounds of expert letter inquiry was 100％,and the expert authority coefficient was 0.836.The Kendall harmony coefficients were 0.471 and 0.820(P＜0.001),and the final non-drug intervention program for pediatric acute chemotherapy-related nausea and vomiting included 5 primary,14 secondary and 18 tertiary items.The results showed that the incidence of nausea,vomiting and negative emotions in the experimental group were lower than that in the control group,with statistically significant differences(P＜0.05).The severity of vomiting was less than it in the control group,with statistically significant difference(P＜0.05).The standard rate of normal sleep time was higher than that of the control group,and the difference was statistically significant(all P＜0.05).Conclusion The non-drug intervention program of chemotherapy-related nausea and vomiting in children is scientific and feasible,and the implementation of the program can reduce the incidence of nausea,vomiting and negative emotions,reduce the severity of vomiting,and improve the standard rate of normal bedtime in children.
