Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Abstract: Objective　To explore the spatial epidemiological characteristics of severe cases hand, foot and mouth disease (HFMD) in Guangxi, China, from 2014 to 2018, and to provide a basis for identifying the high-risk regions as well as the prevention and control of severe cases of HFMD in Guangxi. Methods　Spatial-temporal scanning analysis, global and local spatial autocorrelation analysis were used to analyze the spatial clustering of HFMD. The trend surface analysis was used to evaluate the spatial distribution trend of HFMD. Results　From 2014 to 2018, the incidence and severe case fatality rates of HFMD were 3.89/100 000 and 4.23%, respectively. Monte Carlo scanning analysis showed that the first cluster region was Cenxi City, the second cluster was mainly concentrated in northwest of Guangxi, and the aggregation time was mainly concentrated in April to May and August to October. The global spatial autocorrelation analysis showed that the severe HFMD was significant clustering distribution, and the Moran's I coefficients of the sever cases, severe morbidity and severe case fatality rate were 0.088, 0.118, 0.197, respectively (P<0.05). Local spatial autocorrelation analysis showed that hotspots of severe HFMD cases were concentrated in the southern Guangxi, mainly in Lingshan County. Anselin local Moran's I clustering and outlier analysis indicated that 5 high-high (H-H) clustering regions for fatality were Lingshan, Pubei, Zhongshan, Zhaoping and Pinggui County. There were 6 high-high (H-H) clustering regions for severe incidence rate, namely Lingshan, Qinnan, Lingyun, Youjiang, Bama Yao Autonomous and Pinggui County, and 1 high-low (H-L) clustering region, Cenxi County. The trend surface analysis showed that the overall number of severe cases of death decreased from east or west to the middle, and increased from north to middle, and then decreased to south. Conclusions　Severe HFMD cases in Guangxi have obvious spatial-temporal clustering, and the hop spots are mainly concentrated in southern Guangxi. The prevention and control of HFMD in areas with high incidence of severe cases should be strengthened to reduce the burden of HFMD cases.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective:To observe the effects of Huazhuo Jiedu Shugan Prescription （HZJDSG） on learning， memory， and the expression of phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt）/glycogen synthase kinase-3β （GSK-3β） pathway-related proteins in epileptic rats， and to explore its possible mechanism. Method:Forty-eight SPF male SD rats were randomly divided into a normal group， a model group， a sodium valproate （0.19 g·kg^-1） group， and low- （2.7 g·kg^-1）， medium- （5.4 g·kg^-1）， and high-dose （10.8 g·kg^-1） HZJDSG groups， with eight rats in each group. The normal group received 0.9% sodium chloride solution （0.035 g·kg^-1） by intraperitoneal injection， and the other five groups received pentetrazol （PTZ） at the same dose to induce a chronic epilepsy model for a total of 14 times. The drug groups received corresponding drugs and the normal group and the model group received 0.9% sodium chloride solution at the same volume once a day for 28 days. During the drug intervention period， epilepsy was maintained in each modeling group by intraperitoneal injection of PTZ on day 7， 14， 21， and 28. The behavioral changes of rats were observed by Morris water maze and the pathomorphological changes of rat hippocampal neurons by hematoxylin-eosin （HE） staining. The protein expression of phosphorylation Akt（p-Akt）and p-GSK-3β was detected by immunohistochemistry and the protein expression of PI3K， Akt， p-Akt， GSK-3β， and p-GSK-3β by Western blot. Result:Compared with the normal group， the model group showed prolonged platform finding time （P<0.01）， reduced number of platform crossings （P<0.01）， structural damage of neurons in the CA1 region of the hippocampus， down-regulated protein expression of p-Akt and p-GSK-3β in the CA1 region of the hippocampus （P<0.05）， and reduced relative expression of PI3K， p-Akt， and p-GSK-3β in the hippocampus （P<0.01）. Compared with the model group， the sodium valproate group and the HZJDSG groups showed shortened platform finding time （P<0.01） and improved neuronal structure in the CA1 region of the hippocampus， while the sodium valproate group and the high- and medium-dose HZJDSG groups exhibited increased number of platform crossings （P<0.01）， up-regulated protein expression of p-Akt and p-GSK-3β in the CA1 region of the hippocampus （P<0.05）， and elevated relative expression of PI3K， p-Akt， and p-GSK-3β （P<0.01）. Conclusion:HZJDSG can improve the learning and memory of epileptic rats， and its antiepileptic effect may be achieved by the activation of PI3K/Akt/GSK-3β pathway-related proteins.

Delivering water-soluble drugs via carriers often causes problems such as low loading and rapid releasing, so it is an urgent need to construct a high-load sustained-release drug delivery system for the clinical application of water-soluble drugs. Two-dimensional layered nanomaterials exhibit great potential in drug delivery due to their high specific surface area. In this study, bulk graphitic carbon nitride (b-g-C₃N₄) was obtained by calcination of urea. Graphitic carbon nitride nanosheets (g-C₃N₄-NS) were made from an alkali chemical-ultrasonic-assisted stripping process. Scanning electron microscopy, transmission electron microscopy and atomic force microscopy were adopted to observe the morphological characteristics of g-C₃N₄-NS, while the structural characteristics of g-C₃N₄-NS were analyzed by X-ray diffractometer and Fourier transform infrared spectroscopy. Ultraviolet spectrometry and fluorescence spectrometry were used to investigate the optical properties of g-C₃N₄-NS, and scanning electron microscopy and X-ray diffractometer were employed to investigate the stability of g-C₃N₄-NS. Polyethyleneimine (PEI) was applied in the study to functionally modify g-C₃N₄-NS, and salvianolic acid B (Sal B) was used as a water-soluble drug model to investigate the loading capacity and drug releasing behavior of g-C₃N₄-NS. The results showed that g-C₃N₄-NS had a sheet structure, and it is easy to self-assemble in layers in the ionic environment to create flocculating settling. PEI modification can lead to the switching in the surface charge of g-C₃N₄-NS and significantly improve its stability. The results of cytotoxicity test and zebrafish embryo toxicity test showed that the toxicity was low when the concentration of PEI-g-C₃N₄-NS was less than 800 μg·mL^-1. The large specific surface area and surface charge of PEI-g-C₃N₄-NS allow the maximum load factor over Sal B to reach 327.4%. In addition, PEI-g-C₃N₄-NS can continuously release drugs slowly, with a cumulative release rate of 79.2% in seven straight days. The release process conforms to the Higuchi equation. In summary, g-C₃N₄-NS modified by PEI exhibits good biocompatibility and high stability, and shows great potential in high-load and sustained-release applications of water-soluble drugs.
