OBJECTIVE To evaluate the quality of guidelines/consensus on therapeutic drug monitoring （TDM） of anti-tumor necrosis factor-α （TNF-α） in patients with inflammatory bowel disease （IBD） in China and globally. METHODS PubMed， Embase， CNKI， Wanfang data， VIP， and release websites of guidelines/consensus in China and globally were searched to collect guidelines/expert consensus on TDM with anti-TNF-α for IBD patients. The search period was from database establishment to June 2023. After two investigators independently screened the literature and extracted the data， the methodological quality of the included guidelines/consensuses was evaluated using the Appraisal of Guidelines for Research and Evaluation Ⅱ. The main recommendations of the included guidelines/consensuses were summarized. RESULTS A total of 9 articles were included， 3 were guidelines and 6 were expert consensus. The standardized percentages of the 9 guidelines/consensus in the 6 dimensions （scope and aims， participants， rigor of formulation， clarity of expression， application， and editorial independence） were 90.43%， 41.98%， 52.55%， 85.49%， 19.00%， and 76.85%， respectively. Eight guidelines/consensus had a recommendation of grade B and one consensus of grade C. The main recommendations involve TDM application scenarios， threshold ranges， strategy adjustments， detection methods， and interpretation of results. Most guidelines/consensus recommend passive TDM for non-responders. It is recommended to set the TDM concentration range according to the expected treatment results and make strategy adjustments in combination with the disease condition and TDM results. Additionally， the same test method is recommended for the same patient. Some guidelines/consensus hold that no differences were noted in the interpretation of results between biosimilar and original drug. CONCLUSIONS The overall quality of the included guidelines/consensus was fair， with relatively consistent recommendation. Clinicians need to understand the characteristics and limitations of TDM with this class of drugs， and interpret and apply results of TDM in combination with specific clinical treatment goals.

Objective: To investigate cardiovascular disease (CVD) prevention status among residents with intra-urban migration in Central China, so as to provide insights into targeted prevention and control of CVD. Methods: Basic data of residents aged 35 to 75 years who participated in Early Screening and Comprehensive Intervention Project for CVD high-risk populations in Central China from September 2015 to August 2020 were collected. According to birth place, type of registered residence and current residence, residents were divided into four groups: local residents in old urban area, local residents in new urban area, other urban migrants and other rural migrants. The status of CVD primary and secondary prevention, were analysed by using a robust Poisson regression model. Results: A total of 76 513 residents were recruited, including 29 420 males (38.45%) and 47 093 females (61.55%), and had a mean age of (56.36±9.84) years. There were 45 087 (58.93%) local residents in old urban area, 23 868 (31.19%) local residents in new urban area, 5 668 (7.41%) other urban migrants and 1 890 (2.47%) other rural migrants. After adjusting for variables such as age, gender and educational level, the results of robust Poisson regression analysis showed that compared with local residents in old urban area, local residents in new urban area had lower compliance rates of non- or moderate-drinking (RR=0.987, 95%CI: 0.975-1.000) and healthy diet (RR=0.535, 95%CI: 0.365-0.782), lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.616, 95%CI: 0.511-0.741), lower awareness (RR=0.873, 95%CI: 0.782-0.974) and control rates (RR=0.730, 95%CI: 0.627-0.849) of hypertension; other urban migrants had higher compliance rate of non-smoking (RR=1.045, 95%CI: 1.017-1.075); other rural migrants had lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.826, 95%CI: 0.707-0.966). Conclusion The CVD primaryprevention among local residents in new urban area is relatively poor among four groups of residents in Central China, and key interventions are needed.

Objective To investigate the relationship between correcting abnormal glucose metabolism and mortality risk of malignant tumors of digestive system. Methods A retrospective cohort study was conducted. 1308 patients with abnormal glucose metabolism in our hospital from January 2019 were divided into exposed group (n=777) and non-exposed group (n=531) according to the presence or absence of glucose metabolism correction therapy. The patients were retrospectively followed up until December 2022. The incidence of digestive system tumors and the influencing factors of tumors were compared between the two groups. Results There were 31 patients with digestive system tumor and 9 patients died. The incidence of digestive system tumors was lower in the exposed group (3/777) than in the non-exposed group (28/531). The mortality rate in the exposed group (1/777) was lower than that in the non-exposed group (8/531). Cox regression model analysis showed that correcting abnormal glucose metabolism was a protective factor for the risk of death from malignant tumors of the digestive system in patients (HR value<1, P<0.05) ; increased FBG, combined abnormal lipid metabolism, increased pulse pressure difference, family history of malignant tumors, and alcohol consumption were shown as risk factors for the risk of death from malignant tumors of the digestive system in patients (HR values>1, P<0.05). Conclusion Correcting abnormal glucose metabolism is of positive significance in reducing the risk of death from malignant tumors of digestive system. Patients with increased FBG, abnormal lipid metabolism, increased pulse pressure difference, family history of malignant tumors and alcohol consumption should pay special attention to correct abnormal glucose metabolism in time.

【Objective】 To explore the distribution of serological markers related to samples whose serological test results were inconsistent with HBV DNA test results among voluntary blood donors in Xi′an. 【Methods】 A total of 71 HBsAg ELISA positive and NAT non-reactive (ELISA+ /NAT-)blood samples were collected from Shaanxi Blood Center from November 1, 2022 to April 30, 2023. The serological markers of hepatitis B were detected by electrochemiluminescence method, and the HBV S region and C region gene fragments were amplified by nested-PCR. 【Results】 The positive rate of nested-PCR in double ELISA+ /NAT- group(n=30) was statistically higher than that of ELISA+ /NAT- group(n=41)(60% vs 24.4%, P<0.05). Donors in double ELISA+ /NAT- group were all first-time blood donors, with the positive rate of anti-HBc in serum of 100%, and the serological pattern was mainly positive for items 1, 4 and 5 items(80%). Among the ELISA+ /NAT- group, 31.7% were repeat blood donors, with the positive rate of anti-HBc in serum of only 19.51%, and the serological patterns were mainly single anti-HBs positive (43.90%) and all negative (36.58%). 【Conclusion】 There are false positives in the test results of ELISA+ /NAT- group, which leads to unnecessary blood discarding. Meanwhile, the samples with negative NAT may have low levels of HBV DNA, which may lead to missed detection. It is suggested that multiple systems and methods should be applied to trace the blood donors who are HBsAg positive and NAT non-reactive, so as to improve the accuracy of HBV screening of blood donors and reduce blood waste.

Stroke is one of the most serious complications of transcatheter aortic valve replacement(TAVR),tremendously increasing mortality and the loss of neurocognitive function.Since TAVR is expected to further spread into lower-risk patient groups,there will be greater emphasis to obviate such serious complications.One possible technique for preventing stroke is using cerebral embolic protection devices(CEPDs).CEPDs are designed for capturing or deflecting emboli that are enter route to the brain and hence to protect the brain from embolism.Since this is a rapidly growing field with recent advances,and the impact of CEPD on preventing neurological events is still limited,there is an urgent need for understanding the role of CEPD in preventing clinically significant strokes.Although their clinical utilization is increasing,the risk factors for stroke related to TAVR and evidence for using CEPDs are not yet clear.In this review,we present an overview of the available literature on TAVR related stroke and CEPD,and outline recent advances within this field.

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.

Nanozymes, a groundbreaking discovery by Chinese scientists, represent a novel and remarkable property of nanomaterials. They not only exhibit catalytic activity comparable to natural enzymes, but also boast exceptional stability, tunable reactivity, and the ability to catalyze reactions under mild conditions. The identification of nanozymes has unveiled the biocatalytic potential of inorganic nanomaterials. In parallel, inorganic minerals have long been regarded as pivotal catalysts in the origin of life, driving the synthesis of early biomolecules. These minerals not only facilitate redox reactions that convert simple inorganic compounds into organic molecules but also enable chiral selection, the synthesis of biomacromolecules, and radioprotective functions via their surface structures. Recent advances suggest that inorganic nanomaterials can delicately catalyze the formation of biomolecules, aid in macromolecular assembly, and provide radiation shielding. Furthermore, nanominerals are found in abundance across Earth and extraterrestrial environments. This paper seeks to explore the potential of nanozymes as catalytic agents in the processes that gave rise to life, integrating the catalytic roles of inorganic minerals with the unique attributes of nanozymes, which will provide a new perspective for research of origin of life.
