Diabetes, hypertension, and dyslipidemia, collectively referred to the " Three Highs, " represent increasingly prevalent metabolic risk factors in China. Many individuals experience all three conditions concurrently, significantly heightening the risk of cardiovascular disease and mortality. Although the National Metabolic Management Center(MMC) has been established for over eight years and has its unique features, the awareness, treatment, and control rates of these diseases in China remain low, and the efficiency of community management is insufficient. According to the previous two editions of management guidelines and the most recent domestic and international diagnostic and treatment guidelines, this paper conducts an in-depth analysis of the operational experience and management strategies of the MMC. Its aim is to improve the efficiency of grassroots MMC mode management for " Three Highs" patients and ensure that patients receive more standardized management.

The latest epidemiological data suggests that the situation of adult diabetes in China is severe, and metabolic diseases have become significant chronic illnesses that have a serious impact on public health and social development. After more than six years of practice, the National Metabolic Management Center(MMC) has developed distinctive approaches to manage metabolic patients and has achieved a series of positive outcomes, continuously advancing the standardized diagnosis and treatment model. In order to further improve the efficiency, based on the first edition, the second edition guideline was composed by incorporating experience of the past six years in conjunction with the latest international and domestic guidelines.

End-stage patients experience unbearable pain because of refractory symptoms.Palliative sedation is a form of palliative care which relieves patients' agony by lowering their consciousness.Standard palliative sedation can help patients die with dignity.It is distinct from euthanasia and does not alter the survival of patients.Sufficient palliative care is the premise of palliative sedation.Repeated and detailed clinical evaluation,as well as multidisciplinary involvement,is necessary for the standardized implementation of palliative sedation.Here,we proposed the standard process and specifications of palliative sedation in Peking Union Medical College Hospital.Furthermore,we reported a case of palliative sedation for an advanced cancer patient with refractory delirium and living pain to demonstrate its application in clinical practice.

Chinese patent medicines(CPMs) are unique therapeutic drugs in China. Establishing and improving the evaluation criteria is an important measure to promote the high-quality development of CPMs. Based on the "evaluation criteria of high-grade CPMs with quality as the core index" established by our group in 2018, the "high-quality evaluation criteria for CPMs based on whole process control" was proposed in the present study in 2022. The scope of application and basic principles of the new criteria were clarified. A quality evaluation scoring table was established in the new criteria, including five parts: raw material selection, production process, quality control, efficacy evaluation, and brand building. The technical evaluation indexes involved have increased from 20% in the original criteria to 70% in the new criteria, and efficacy evaluation has been added in the new criteria. The subjective evaluation indicators account for a large proportion in the original criteria, which is prone to bias. The improved criteria overcome this shortcoming. It is expected that the new criteria as a basis can play a better role in the selection of high-quality products of CPMs, guide enterprises and institutions to participate actively in the evaluation and research of high-quality CPMs, and promote the high-quality development of CPMs.

The big brand of Chinese patent medicine, Fufang Danshen Prescription(FDP), effective in promoting blood circulation, resolving blood stasis, regulating qi, and relieving pain, is wide in clinical application and diverse in dosage forms and products, but its quality and price are uneven, which causes problems for doctors and patients. To clarify the key links and weakness of quality control leading to the quality difference of FDP products, the present study carried out a comprehensive evaluation of the whole production cycle of FDP based on the "high-quality Chinese patent medicine evaluation criteria" and analyzed the advantages and disadvantages of production and quality of different FDP products according to scores. The results showed that the scores of various products in the "raw materials selection" varied greatly. The highest score(S1) and the lowest score(S2) differed by more than 3 times, indicating that different manufacturers had inconsistent requirements for the selection of raw materials, leading to fundamental differences in the quality of raw materials. The scores in the "production process" varied slightly, with an average score of 66.8%. The manufacturer S8 obtained the highest score(84.0%), which indicated the emergence of intelligent manufacturing production. The scores(with the average score of 44.0%) in the "quality control" were lower than those of the previous two items, which was attributed to the fact that most FDP products only met the "qualified" benchmark required by the 2020 edition of Chinese Pharmacopoeia, and their consistency and high quality were both uncontrollable. The scores in the "post-marketing research" were the lowest(with an average score of 28.5%), and most manufacturers were scored 0, which reflected little attention paid. Only a few brand manufacturers were scored acceptably and they were willing to carry out relevant research on post-marketing evaluation. The evaluation results demonstrated the key links and weakness leading to the production and quality differences of FDP from different manufacturers. It is expected to improve the quality of FDP, promote the formation of the "high quality and good price" mechanism, and provide information for the centralized procurement of governments.

Modified Da-chai-hu Decoction (MDD), a traditional Chinese medicinal formulation, which was empirically generated from Da-chai-hu decoction, has been utilized to treat severe acute pancreatitis (SAP) for decades. The aim of the present study was to explore its potential organprotective mechanism in SAP. In the present study, rat SAP model was induced by retrograde injection of 3.5% sodium taurocholate into the biliopancreatic duct, MDD (23.35 g/kg body weight, twelve times the clinical dose) were orally given at 2 h before and 10 h after injection. At 12 h after model induction, blood was taken from vena cava for analysis of amylase, diamine oxidase (DAO), pulmonary surfactant protein-A (SP-A), and C-reactive protein (CRP). Histopathological change of pancreas, ileum and lung was assayed by H&E staining, myeloperoxidase (MPO) activity were determinated using colorimetric assay, and the expressions of occludin and nuclear factor-κB (NF-κB) were detected by real-time RT-PCR and western blot, respectively. In addition, the tissue concentrations of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and monocyte chemoattractant protein-1 (MCP-1) were measured by enzyme-linked immunosorbent assay (ELISA). The results showed that in SAP rats, MDD significantly alleviated histopathological damage, depressed the MPO activity and the concentrations of TNF-α, IL-1β, and MCP-1 of pancreas, ileum and lung, and reduced the serum levels of amylase [(3283.4 ± 585.5) U·Lvs (5626.4 ± 795.1)U·L], DAO [(1100.1 ± 334.3) U·Lvs (1666.4 ± 525.3) U·L] and CRP [(7.6 ± 1.2) μg·mLvs (17.8 ± 3.8) μg·mL]. However, the serum SP-A concentration [(106.1 ± 16.6) pg·mLvs (90.1 ± 14.9) pg·mL] was elevated when treated SAP rats with MDD. Furthermore, MDD increased the occludin expression and reduced the NF-κB expression in pancreas, ileum and lung of SAP rats. Our findings suggested that MDD administration was an effective therapeutic approach for SAP treatment. It could up-regulate occludin expression to protect intercellular tight junction and down-regulate NF-κB expression to inhibit inflammatory reaction of pancreas, ileum and lung.
