ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory， Qijia Rougan prescription， combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted， and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis （CHB-HF） who met the diagnosis and inclusion criteria were randomly assigned to an observation group （Qijia Rougan prescription + entecavir） and a control group （entecavir）. The treatment duration was 24 weeks. Liver stiffness measurement （LSM）， fibrosis-4 index （FIB-4）， portal vein diameter， hepatitis B serology， biochemical indicators， hepatic fibrosis markers in serum ［hyaluronic acid （HA）， laminin （LN）， procollagen Ⅲ peptide （PⅢP）， and type Ⅳ collagen （Ⅳ-C）］， and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis， with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment， the observation group showed a significant reduction in LSM and FIB-4 （P<0.01）， as well as notable improvements in LN， Ⅳ-C， and various TCM syndrome scores （P<0.05， P<0.01）. When compared to the control group after treatment， the observation group demonstrated significant improvements in LSM， FIB-4， and various TCM syndrome score indicators （P<0.05， P<0.01）， indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment， the observation group had better improvement in regression of stages F2 and F3 （P<0.05）. When compared to the control group after treatment， the observation group exhibited superior improvement in regression of stage F3 （P<0.05）. No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone， the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3， which is a potential “interception” point of the “Zhu Ke Jiao” theory.

Enhanced recovery after surgery (ERAS) is a series of perioperative optimization measures based on evidence-based medicine aimed at achieving rapid recovery. Existing studies have shown that ERAS can effectively reduce surgical stress, decrease the incidence of complications, shorten hospital stays, save medical costs, and improve patient satisfaction. Although lung transplantation techniques have become increasingly mature, lung transplant recipients still have a high incidence of complications during perioperative period. To further improve the perioperative survival rate of lung transplant recipients, introducing ERAS concept into the perioperative management strategy of lung transplantation is of great significance for reducing incidence of perioperative complications, promoting rapid recovery and long-term survival of lung transplant recipients. This article discusses the advances in application of ERAS concept in the perioperative management of lung transplantation, aiming to provide references for optimizing the perioperative management of lung transplant recipients and reducing perioperative complications.

OBJECTIVE: To investigate the effect of 5-hydroxytryptamine (5-HT) on the proliferation, apoptosis and colony-forming unit-megakaryocyte (CFU-MK) of Meg-01 cells and its possible mechanisms. METHODS: The uptake and metabolism of 5-HT in Meg-01 cells were analysed by reverse-phase high-performance liquid chromatography (RP-HPLC) with electrochemical detection. The expression of 5-HT2B receptor (5-HT2BR) in megakaryocytes was detected by immunofluorescence staining. The cell proliferation and viability were measured by MTT and Trypan blue staining after Meg-01 cells were single-cultured or co-cultured with different concentrations of 5-HT/5-HT2BR inhibitor Ketanserin for 48 h. Meg-01 cells were incubated with 5-HT/ Ketanserin for 72 h, then the flow cytometry was used to detect early apoptosis of the cells and the activity of caspase-3. Using CFU-MK assay to investigate the effect of 5-HT on the differentiation of megakaryocytes. RESULTS: 5-HT could be uptaken by Meg-01 cells, and metabolized into 5-hydroxyindoleacetic acid (5-HIAA). The expression of 5-HT2BR on megakaryocytes could be detected after immunofluorescence staining. 5-HT could promote the proliferation of Meg-01 cells at a dose-dependent manner (r =0.82), with the most significant effect observed at a concentration of 200 nmol/L (P < 0.001). Trypan blue staining also indicated that 200 nmol/L 5-HT had the most significant effect on the viability of Meg-01 cells (P < 0.05). The proliferation of Meg-01 cells treated with 5-HT was increased compared with the untreated control (P < 0.001), while the combination of 5-HT with ketanserin downregulated this effect. 5-HT significantly reduced the early apoptosis rate (P < 0.001) and caspase-3 activity (P < 0.05) of Meg-01 cells, while addition of ketanserin significantly increased the early apoptosis rate of Meg-01 cells (P < 0.001) and caspase-3 activity also increased to some extent. 5-HT promoted the formation of CFU-MK in bone marrow cells in a dose-dependent manner (r =0.89). The addition of ketanserin reduced the promoting effect of 5-HT on CFU-MK formation (P < 0.01). CONCLUSION There may be monoamine oxidase present in megakaryocytes, which can metabolize and decompose 5-HT into 5-HIAA. 5-HT may promote the proliferation and differentiation of megakaryocytes through 5-HT2BR. Besides, 5-HT can also reduce the apoptosis of megakaryocytes, and its anti-apoptotic effect may be mediated by 5-HT2BR and caspase-3 pathways.

Objective To explore the developmental trajectories of oral hygiene compliance and its influencing factors in children after dental caries surgery.Methods A prospective cohort study design was adopted.A total of 268 children who underwent dental caries surgery were selected as the research subjects.General and clinical data of the children were collected.The oral hygiene compli-ance changes after surgery were evaluated using the Oral Hygiene Compliance Scale.The develop-mental trajectories of oral hygiene compliance after surgery were described using the group-based traj-ectory model.Multivariate Logistic regression analysis was used to explore the influencing factors of the compliance developmental trajectories.Results The oral hygiene compliance of children after dental caries surgery could be divided into three types of developmental trajectories:the high-compliance slow-decline group[49(18.28％)],the medium-compliance slow-decline group[56(20.90％)],and the low-compliance stable-change group[163(60.82％)].Multivariate Logistic regression analysis showed that the child's gender,mother's educational level,fathers smoking history,annual per capi-ta household income,Social Support Scale score,Oral Health Self-Efficacy Scale score,and Expec-ted Social Impact Scale score were all independent influencing factors for the oral hygiene compliance to present different types of developmental trajectories(P＜0.05).Conclusion The oral hygiene compliance of children after dental caries surgery presents different types of developmental trajectories,and there are individual differences in their initial compliance levels and rates of change.Clinically,oral hygiene care intervention measures should be implemented according to the specific conditions of children to maintain their oral health.

OBJECTIVE: To analyze the clinical characteristics of a patient with Short rib-polydactyly syndrome type 6 (SRTD6) with long-term misdiagnosis, and improve its clinical recognition by reviewing the relevant literature. METHODS: A patient presented at the Children's Hospital Affiliated to Zhejiang University School of Medicine on August 19, 2024 for the discovery of liver dysfunction for 13 years and vision loss for 9 years was selected as the study subject. Her medical history, clinical data, laboratory findings and results of imaging examination were collected. High-throughput sequencing was carried out, and candidate variants were verified by Sanger sequencing. This study was approved by the Ethics Committee of the Hospital (Ethics No.: 2021-IRB-292). RESULTS: The patient had long-term unexplained liver dysfunction, vision loss, and growth delay. Blood acylcarnitine and urinary organic acid analysis have failed to found any abnormality. Previous genetic testing revealed a homozygous c.203A>C (p.Glu68Ala) missense variant in the ETFDH gene, leading to a misdiagnosis of various acyl-CoA dehydrogenase deficiencies. However, treatment with high-dose vitamin B₂ showed a poor effect. Physical examination revealed small hands, short and stubby fingers, and a narrow chest. Medical imaging showed shortened bilateral ribs, a narrowed chest, and short, thick metacarpals. High-throughput sequencing has detected a pathogenic homozygous c.1957C>T (p.R653*) nonsense variant in the NEK1 gene, confirming the diagnosis of SRTD6. CONCLUSION SRTD6 is characterized by rib and sternum dysplasia as the primary skeletal deformities, which is often accompanied by multi-organ impairment. Genetic testing can facilitate the precise diagnosis.

ObjectiveTo explore the clinical effectiveness and safety of stick-point sinew-soothing and bone-setting manipulation for scapulohumeral periarthritis. MethodsUsing prospective randomised controlled trial method， 60 cases of patients with scapulohumeral periarthritis were collected and randomly divided into 30 cases each in control group and trial group. Both groups of patients were orally treated with celecoxib， on the basis of which the control group was treated with traditional bonesetting manipulation once every other day for 14 days， while the trial group was treated with stick-point sinew-soothing and bone-setting manipulation once every 3~5 days for 14 days. Both groups were treated for 2 courses. The main observation indexes were pain visual analogue scale （VAS） score and shoulder pain and dysfunction index （SPADI）， which were evaluated once before treatment and after 2 and 4 weeks of treatment. The secondary effectiveness indicators included the university of California at Los Angeles shoulder rating scale （UCLA）， traditional Chinese medicine syndrome score （including symptom scores as joint pain， pain in a fixed place， activity limitation， local stiffness）， and serum interleukin （IL-6） and tumour necrosis factor α （TNF-α） levels before and after the treatment， in order to evaluate the clinical effectiveness， and to record the adverse reactions that occurred in the process of diagnosis and treatment. ResultsCompared with the groups before treatment， the pain VAS score， SPADI and scores of joint pain， pain with a fixed place， activity limitation and local stiffness were lower， UCLA score was higher， and serum IL-6 and TNF-α levels were lower at 4 weeks of treatment in the two groups （P＜0.05）. When comparing the two groups between the groups at 2 and 4 weeks of treatment， the pain VAS score， SPADI and TCM scores of each symptom in the study group were lower than those in the control group， the UCLA score was higher than those in the control group （P＜0.01）， and the serum IL-6 and TNF-α levels were lower than those in the control group at 4 weeks of treatment （P＜0.01）. The clinical effectiveness rate of the study group was 66.67%， which was significantly higher than that of the control group， which was 40.00% （P = 0.038）. No adverse reactions were seen in both groups during the study. ConclusionCompared with the traditional massage manipulation， the treatment of scapulohumeral periarthritis with stick-point sinew-soothing and bone-setting manipulation has more advantages in relieving pain symptoms， reducing inflammatory reaction， and promoting the recovery of shoulder joint function.

Objective To summarize the epidemiological and clinical features of infectious diseases of the central nervous system(CNS)by a single-center analysis.Methods A retrospective analysis was conducted on the data of 1247 cases of CNS infectious diseases diagnosed and treated in the First Medical Center of PLA General Hospital from 2001 to 2020.Results The data for this group of CNS infectious diseases by disease type in descending order of number of cases were viruses 743(59.6％),Mycobacterium tuberculosis 249(20.0％),other bacteria 150(12.0％),fungi 68(5.5％),parasites 18(1.4％),Treponema pallidum 18(1.4％)and rickettsia 1(0.1％).The number of cases increased by 177 cases(33.1％)in the latter 10 years compared to the previous 10 years(P<0.05).No significant difference in seasonal distribution pattern of data between disease types(P>0.05).Male to female ratio is 1.87︰1,mostly under 60 years of age.Viruses are more likely to infect students,most often at university/college level and above,farmers are overrepresented among bacteria and Mycobacterium tuberculosis,and more infections of Treponema pallidum in workers.CNS infectious diseases are characterized by fever,headache and signs of meningeal irritation,with the adductor nerve being the more commonly involved cranial nerve.Matagenomic next-generation sequencing improves clinical diagnostic capabilities.The median hospital days for CNS infectious diseases are 18.00(11.00,27.00)and median hospital costs are ￥29,500(￥16,000,￥59,200).The mortality rate from CNS infectious diseases is 1.6％.Conclusions The incidence of CNS infectious diseases is increasing last ten years,with complex clinical presentation,severe symptoms and poor prognosis.Early and accurate diagnosis and standardized clinical treatment can significantly reduce the morbidity and mortality rate and ease the burden of disease.

Objective To compare the ultrasound signs of symptomatic joint lesions in rheumatoid arthritis (RA) and gouty arthritis (GA), musculoskeletal ultrasound (MSUS) was utilized.Methods A retrospective analysis was performed for 85 hospitalized patients with RA and 55 hospitalized patients with GA in the same period, and the differences in general data, diseased joints and ultrasound signs between the two groups were compared.Re-sults The gender, age and diseased joints of the two groups were statistically significant (all P<0.05).The de-tection rate of knee joint lesions was the highest;the RA group had high sensitivity, high specificity of meniscal in-jury, and high diagnostic efficiency of bone erosion, while the diagnostic performance of the three combined ultra-sound signs of punctate strong echo, double track sign and tophi in the GA group was higher than that of any indi-vidual diagnosis, and the sensitivity and specificity were also higher.The course of disease in the RA group was positively correlated with bone erosion (P<0.05) , and the course in the GA group was positively correlated with tophi (P<0.05).Conclusion The ultrasound signs of RA and GA are different, and MSUS has good value in the diagnosis and differential diagnosis of the two.
