ObjectiveTo analyze the long-term trends of the disease burden of diabetes attributed to metabolic factors in China from 1990 to 2019, and provide scientific recommendations for diabetes prevention and control in China. MethodsDescriptive analysis was conducted on the disease burden data of diabetes attributed to metabolic factors in China from 1990 to 2019, obtained from GBD 2019, encompassing death form diabetes, disability-adjusted life years (DALY), years of life lost (YLL), and years lived with disability (YLD). Joinpoint regression models were employed to analyze the long-term trends in mortality and DALY rates. Furthermore, the study examined the impact of two metabolic risk factors, high fasting plasma glucose (FPG) levels and high body mass index (BMI) levels, on the disease burden of diabetes. ResultsFrom 1990 to 2019, the overall standardized mortality and DALY rates attributed to metabolic factors for diabetes in the general population in China showed an upward trend, with both average annual percent changes (AAPCs) of 0.1% in the total population. The trend was upward in males with AAPCs of 0.9% and 0.6%, while it was downward in females with AAPCs of -0.4% and -0.3%. As age increased, the disease burden of diabetes attributed to metabolic factors showed an upward trend, with high FPG and high BMI ranking as the top two attributing risk factors. The disease burden of diabetes attributed to metabolic factors was higher in Chinese males than females. ConclusionThe disease burden of diabetes attributed to metabolic factors is increasing among the overall population and particularly among males, while the burden for female is declining. There is a need to increase intervention efforts for males aged 65 and above, provide scientific guidance on residents’ diet and lifestyle habits, and control blood glucose and body weight.

This study using maltodextrin as raw material, 1%-5% polyvinylpyrrolidone K30 as template agent, 1%-5% ammonium bicarbonate as pore-forming agent, curcumin and ibuprofen as model drugs. Porous maltodextrin was prepared by template and pore-forming agent methods, respectively. The structure and drug delivery behavior of porous maltodextrin prepared by different technologies were comprehensively characterized. The results showed that the porous maltodextrin prepared by pore-forming agent method had larger specific surface area (6.449 4 m²·g^-1) and pore size (32.804 2 nm), which was significantly better than that by template agent method (3.670 2 m²·g^-1, 15.278 5 nm). The adsorption kinetics between porous maltodextrin prepared by pore-forming agent method and curcumin were suitable for quasi-first order adsorption kinetic model, and that between porous maltodextrin and ibuprofen were suitable for quasi-second order adsorption kinetic model. While the adsorption kinetics between porous maltodextrin prepared by template agent method and two model drugs were both suitable for the quasi-first order adsorption kinetic model. In addition, the dissolution behavior analysis showed that the porous maltodextrin prepared by the two technologies can significantly improve the dissolution behavior of insoluble drugs, and the drug release was both carried out by diffusion mechanism, which suitable for the Peppas kinetic release model, but the porous maltodextrin prepared by template agent method had a faster release rate. The change of nozzle diameter had no significant effect on the adsorption process and drug release behavior of porous maltodextrin. In conclusion, the porous maltodextrins prepared by two different technologies were both beneficial to the delivery of insoluble drugs, and the template agent method was the best for delivery of insoluble drugs. This study can provide theoretical basis for the preparation of porous particles, promote the application of porous particles in insoluble drugs, and improve the bioavailability of insoluble drugs.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective To develop and evaluate the equivalence of the Mandarin test material for tracking of noise tolerance(TNT)test.Methods Six different speech materials were developed(themes including daily life,entertainment,family,festivals,outdoors,and school).Four-minute TNT tests were measured in 21 normal hear-ing subjects using six different test materials.For each session,the tolerable noise level(TNL)and TNT scores were acquired and calculated for 3 time windows(31～240 s,31～120 s,151～240 s).Results Statistic analysis showed significant differences in the TNL(F=43.611,P＜0.05)among the normal hearing listeners.There were statistically significant differences in standardize z-scored TNT scores of the six different materials in the three time windows(P＜0.05).Post-hoc comparisons revealed that all significant differences involved the family and daily life themes.Conclusion Entertainment,festival,outdoors and school themed test materials can serve as the materials of Mandarin tracking of noise tolerance test and can be appied in research and clinical testing.

Objective: To summarize the clinical characteristics of patients with skip metastasis at esophageal resection margin during radical gastrectomy. Methods: This is a descriptive study of case series. Relevant data from 2006 to 2022 were collected from two major gastric cancer consultation and treatment centers: Nanjing Drum Tower Hospital and Jinling Hospital.Characteristics, surgical approach, number of dissected lymph nodes, immunohistochemical staining, and pathological staging were summarized and analyzed. The distribution of residual tumor cells at the esophageal margins was further analyzed at the cellular and tissue levels. Skip metastasis at the esophageal resection margin was defined as a negative esophageal margin with a positive margin in the cephalad donut. Results: Thirty (0.33%, 30/8972) eligible patients, 24 (80.0%) of whom were male, were identified in the two centers. The mean age was 63.9±11.0 years. Seventeen (56.7%) of these patients had papillary or tubular adenocarcinomas, including 13 (43.3%) poorly- and four (13.3%) moderately-differentiated tumors; four (13.3%) had signet-ring cell carcinomas; four (13.3%) mucinous adenocarcinomas; three (10.0%) mixed adenocarcinomas, including two with poorly-differentiated tubular adenocarcinomas mixed with signet-ring cell carcinoma and mucinous adenocarcinoma; and one had a poorly differentiated tubular adenocarcinoma mixed with signet-ring cell carcinoma. Two patients (6.7%) had other types of cancer, namely adenosquamous carcinoma in one patient and undifferentiated carcinoma in the other one. The predominant tumor sites were the lesser curvature (n=26, 86.7%) and the cardia (n=24, 80.0%). The mean tumor diameter was 6.6 cm, mean distance between tumor and esophageal resection margin was 1.5 cm, and proportions of tumor invasion into the dentate line, nerves, and vessels were 80.0% (24/30), 86.7%(26/30), and 93.3% (28/30), respectively. The mean number of lymph nodes resected was 20.4±8.9. The pathological stage was mainly T4 (n=18, 60.0%) and N3 (n=21, 70.0%), the median Ki67 was 52.7%, and the rates of positivity for HER2, EGFR, VEGFR, E-cadherin and PD-L1 were 40.0% (12/30), 46.7% (14/30), 80.0% (24/30), 86.7% (26/30) and 16.7% (5/30), respectively. At the cellular level, cancer cells were mainly distributed in small focal areas, as cell masses, or as tumor thrombi; large numbers of widely distributed atypic cells were seldom observed. At the tissue level, cancer cells were located in the mucosal layer in seven patients (23.3%), in the submucosal layer in 18 (60.0%), and in the muscular layer in five (16.7%); no cancer cells were identified in the outer membrane. Five of the seven tumors were located in the lamina propria, two in the muscularis mucosae, and none in the mucosal epithelium. Conclusion: Patients with skip metastasis at the esophageal resection margin at radical gastrectomy have unfavorable tumor biology and a high proliferation index, are at a late pathological stage, and the residual cancer is mostly located in the submucosa.

A flavoring agent and a suspension agent were prepared for extemporaneous compounding. The stability of the two agents before and after drug loading was investigated, and the taste of the suspension after extemporaneous compounding was evaluated by electronic tongue technology. The two agents remained stable under the conditions of influence factor test, accelerated test and long-term test. The appearance properties of the two agents did not change. The relative density of the flavoring agent was maintained at 1.053-1.075, and the pH was stable at 4.2-4.5. The relative density of the suspension agent was maintained at 0.999-1.022, and the pH was stable at 4.0-4.5. Seven kinds of drugs, including warfarin sodium tablets and spironolactone tablets, were mixed with these two oral solvents, and the content uniformity and stability were detected respectively. The results showed that the preparations could be evenly dispersed and the physical and chemical properties were stable. The results of taste evaluation showed that in captopril group and chloral hydrate group, the flavoring agent had the best effect on taste correction. In warfarin sodium group, rifampicin group, spironolactone group, vitamin B1 group and vitamin B2 group, the blending agents had the best effect on taste correction.

Currently, the gut-organ axis has become a hot research topic. As increasing attention has been paid to the role of gut microbiota in the health of organs, the complex and integrated dialogue mechanism between the gastrointestinal tract and the associated microbiota has been demonstrated in more and more studies. Skin as the largest organ in the human body serves as the primary barrier protecting the human body from damage. The proposal of the gut-skin axis has established a bidirectional link between the gut and the skin. The disturbance of gut microbiota can lead to the occurrence of skin diseases, the mechanism of which is complex and may involve multiple pathways in immunity, metabolism, and internal secretion. According to the theory of traditional Chinese medicine(TCM), the connection between the intestine and the skin can be established through the lung, and the interior disorders will definitely cause symptoms on the exterior. This paper reviews the research progress in the gut-skin axis and its correlation with TCM theory and provides ideas and a basis for cli-nical treatment and drug development of skin and intestinal diseases.

OBJECTIVE: To investigate the effect of biflavonoid 4'-O-methylochnaflavone (MF) on palmitic acid-induced endothelial dysfunction in rat cavernous endothelial cells (RCECs). METHODS: The isolated RCECs were commercially available and randomly divided into four groups: normal+BSA group (NC group), palmitic acid (PA) group, MF group, and icariside Ⅱ (ICA Ⅱ) group. The protein expression levels of protein kinase B (PKB/AKT) and endothelial nitric oxide synthase (eNOS) in each group were evaluated via Western blotting. The differences in the intracellular nitric oxide of RCECs treated by MF or ICA Ⅱ were detected by DAF-FM DA that served as a nitric oxide fluorescent probe. Effects of MF and ICA Ⅱ on cell proliferation of PA-stimulated RCECs were determined via CCK-8 assay. RESULTS: The content of nitric oxide in RCECs was significantly increased after the treatment of MF and ICA Ⅱ in comparison with the NC group (P < 0.05). Moreover, compared with ICA Ⅱ group, MF demonstrated a more obvious effect in promoting nitric oxide production (P < 0.05). Compared with the NC group, the expression levels of eNOS and AKT in the PA group were significantly decreased, indicating that a model for simulating the high-fat environment in vitro was successfully constructed (P < 0.05). Meanwhile, the intervention of MF and ICA Ⅱ could effectively increase the expression of eNOS and AKT, suggesting that MF and ICA Ⅱ could promote the recovery of endothelial dysfunction caused by high levels of free fatty acids (P < 0.05). The results of CCK-8 assays showed that PA could significantly reduce the proli-feration ability of RCECs (P < 0.05). Furthermore, the decreased cell viability induced by PA was significantly elevated by treatment with ICA Ⅱ and MF (P < 0.05). CONCLUSION In RCECs, MF and ICA Ⅱ could effectively increase the content of nitric oxide. The down-regulation of the expression of proteins associated with the AKT/eNOS pathway after PA treatment revealed that this pathway was involved in the development of endothelial dysfunction, which could be effectively reversed by MF and ICA Ⅱ. In addition, the cell proliferation ability was significantly decreased following PA treatment, but MF and ICA Ⅱ could restore the above changes. Overall, biflavonoid MF has an obvious repairing effect on PA-stimulated endothelial dysfunction.

OBJECTIVE: To investigate the value of HBV RNA for predicting the therapeutic effect of long-term entecavir (ETV) antiviral therapy in patients with chronic hepatitis B (CHB). METHODS: Serum samples were collected from 59 CHB patients treated with ETV for 96 or 108 months. HBV RNA levels, HBV DNA levels, and serological marker (HBeAg) levels were measured at baseline and 3, 6, 9, 12, 36, 72, and 96 (or 108) months during the therapy. RESULTS: Although HBV RNA level decreased after 12 and 36 months of ETV antiviral therapy, no significance changes occurred in HBV RNA negative conversion rate (P>0.05). After 72 months of treatment or longer, 33 patients had HBV RNA levels lower than 100 copies/mL, and among them 29 patients had HBV RNA levels lower than the detection limit, and HBV RNA negative conversion rate was statistically significant (P < 0.05). A lower HBV RNA level was associated with a higher HBeAg negative conversion rate (P < 0.05). Age and HBV RNA level were positively correlated with HBeAg negative conversion rate (P < 0.05). CONCLUSION Prolonged ETV antiviral therapy results in better clearance of HBV RNA and a higher negative conversion rate in CHB patients. The length of antiviral therapy and age are positively correlated with the negative conversion rate of HBV RNA, and earlier administration of the antiviral treatment achieves better therapeutic effect. Serum HBV RNA level can be used as an indicator for predicting conversion to negative HBeAg in CHB patients receiving ETV therapy.

This study aimed to forecast the main active components of Xiaoer Chiqiao Qingre Granules(XECQ) in the treatment of children with acute upper respiratory tract infection by UPLC-MS, network pharmacology, molecular docking and cell biology, and explore the mechanism of action, so as to provide certain reference for the research on its pharmacodynamics substances and mechanism of action. The main chemical components of XECQ were comprehensively analyzed by UPLC-Q-TOF-MS combined with UNIFI platform. According to the MS1 and MS2 data of XECQ, comparison and identification were carried out in combination with reference substances and reference articles. On this basis, the chemical components of XECQ were targeted and enriched by network pharmacology, to screen the main pharmacodynamic substances of XECQ in the treatment of acute upper respiratory tract infection in children and discuss the mechanism of action. In addition, the binding degree of core targets and main active components was verified by molecular docking. The results revealed that 202 compounds were identified from XECQ, among which 22 were the main active components, including obovatol, dihydroartemisinin, and longikaurin A. Enrichment analysis of the key target pathways showed that XECQ played its role in the treatment of children with acute upper respiratory tract infection mainly by regulating PI3K/Akt signaling pathway and MAPK signaling pathway. In the experimental verification by Western Blot(WB), it was found that XECQ significantly inhibited the expression of PI3K and Akt, which was consistent with the prediction results of network pharmacology. In conclusion, the potential pharmacodynamic substances of XECQ were obovatol, dihydroartemisinin, longikaurin A and other 19 active components. It treated children with acute upper respiratory tract infection by regulating the PI3K/Akt signaling pathway.
