Objective To analyze the effect of releasing the lower pulmonary ligament on right residual lung expansion after right upper lobe resection under different body mass index (BMI) levels. Methods The clinical data of patients who underwent thoracoscopic right upper lobe resection in the First Affiliated Hospital with Nanjing Medical University from 2021 to 2022 were retrospectively analyzed. Patients were divided into a group A (17 kg/m2<BMI≤23 kg/m2), a group B (23 kg/m2<BMI≤29 kg/m2) and a group C (BMI>29 kg/m2) according to BMI. The presence of residual cavity was judged by chest X-ray at 7-10 days after operation, the degree of compensation change of the right main bronchus angle was measured, and the changes in lung volume were determined by CT three-dimensional reconstruction. Results A total of 157 patients who underwent thoracoscopic right upper lobe resection were included, including 71 males and 86 females, with an average age of (59.7±11.2) years. There were 50 patients in the group A, 75 patients in the group B, and 32 patients in the group C. In the group A, compared with those without releasing the lower pulmonary ligament, patients with releasing had a lower incidence of postoperative residual cavity (P=0.016), greater changes in bronchus angle (P<0.001), and smaller changes in lung volume (P<0.001). In the group B and C, there was no significant effect of releasing the lower pulmonary ligament on postoperative residual cavity, bronchus angle, and lung volume changes (P>0.05). Conclusion For patients with thin and long body shape and low BMI, releasing the lower pulmonary ligament is helpful to promote the expansion of the residual lung after right upper lobe resection and reduce the occurrence of postoperative residual cavity in patients.

Objective:
To investigate the effect of different surface treatment protocols on the surface properties and immediate shear bond strength (SBS) between 3D-printed zirconia and resin cement to provide a reference for clinical practice.
Methods:
Disc-shaped zirconia specimens (Ø 14 mm× 1.2 mm) with two different surface designs were fabricated using 3D printing technology: a smooth surface (Group S) and microporous surface (Group M), with 40 specimens in each group. Each group was further randomly divided into four subgroups according to surface treatment: untreated (Subgroup U), alumina sandblasting (Subgroup ST), alumina sandblasting + Z-Prime ceramic primer (Subgroup ZP), and alumina sandblasting + Monobond N ceramic primer (Subgroup MN). The surface morphology was examined, roughness was measured, and wettability was evaluated via contact-angle testing. Composite resin cylinders (Ø 3.5 mm× 2.0 mm) were bonded to the zirconia surfaces with resin cement. Immediate SBS was determined by shear testing, and failure modes were analyzed.
Results:
Scanning electron microscopy revealed clear micro-grooves (2-5 μm wide) in Subgroup S-U and micropores (approximately 400 μm in diameter) in Subgroup M-U. After sandblasting, the micro-grooves in Subgroup S-ST were partially destroyed with some micro-cracks, while the microporous structure in Subgroup M-ST remained clear. Compared with Subgroups S-U and M-U, sandblasted zirconia specimens (Subgroups S-ST, S-ZP, S-MN, M-ST, M-ZP, M-MN) showed significantly increased roughness and decreased contact angles. Different surface treatments significantly affected SBS between 3D-printed zirconia and resin. Sandblasted groups (Subgroups S-ST and M-ST) had significantly higher SBS than untreated groups (Subgroups S-U and M-U). The application of ceramic primers after sandblasting (Subgroups S-ZP, S-MN, M-ZP, M-MN) further increased SBS; however, there was no statistically significant difference in SBS between the two primers used after sandblasting (Subgroup S-ZP vs. S-MN, Subgroup M-ZP vs. M-MN). Under the same surface treatment, microporous surface groups (Subgroups M-U, M-ST, M-MN, M-ZP) all exhibited significantly higher SBS than smooth surface groups (Subgroups S-U, S-ST, S-MN, S-ZP).
Conclusion
Fabricating a microporous surface using 3D printing technology can improve resin bonding effectiveness. Sandblasting combined with a ceramic primer yields the highest immediate SBS.

OBJECTIVE To investigate the effects and potential mechanism of curcumin on neurological injury in neonatal rats with bacterial meningitis based on the signal transducer and activator of transcription 1( STAT1)/ nucleotide-binding domain leucine- rich repeat and pyrin domain-containing receptor 3 (NLRP3) signaling pathway. METHODS Neonatal rats, with an equal number of males and females, were randomly divided into control group, model group, curcumin low-dose (Cur-L), medium-dose (Cur- M) and high-dose (Cur-H) groups, and Cur-H+STAT1 transcription enhancer [2-(1,8-naphthyridin-2-yl)phenol] group (Cur-H+2- NP group), with 15 rats in each group. Except for the control group, rats in other groups were injected with a suspension of group B Streptococcus (1×104 cfu/mL, 10 μL) into the cerebellomedullary cistern to establish a bacterial meningitis model. After successful model establishment, rats in Cur-L, Cur-M and Cur-H groups were intraperitoneally injected with 1.25, 2.5 and 5 mg/kg curcumin, respectively, and those in the Cur-H+2-NP group were intraperitoneally injected with 5 mg/kg curcumin and 0.5 mg/kg 2- NP, once a day, for 3 consecutive weeks. After the last administration, modified Loeffler score was conducted, white blood cells (WBC) count in cerebrospinal fluid as well as the contents of inflammatory factors [tumor necrosis factor-α, interleukin-6 (IL-6), IL-1β and IL-18], brain water content and blood-brain barrier permeability were detected; the histopathological changes of hippocampus and cortex tissues were observed. The percentage of apoptosis in hippocampal/cortical tissue cells, the positive expression of ionized calcium-binding adapter molecule-1 (Iba-1), the co-localization of Iba-1 and NLRP3, as well as the expressions of proteins related to the STAT1/NLRP3 signaling pathway (phosphorylated STAT1, NLRP3, apoptosis-associated speck-like protein containing a CARD, gasdermin D, caspase-1, IL-1β and IL-18) were examined. RESULTS Compared with the control group, the neurons in the hippocampal/cortical tissues of rats in the model group exhibited significant morphological abnormalities, accompanied by neuronal edema and necrosis, as well as infiltration of inflammatory cells. The modified Loeffler score and the number of Nissl bodies were significantly decreased/reduced in the model group, while the WBC count, levels of inflammatory factors, brain water content, blood-brain barrier permeability, HE staining score, number of degenerated neurons, percentage of apoptotic cells, positive expression of Iba-1, percentage of Iba-1 and NLRP3 co-localization- positive cells, and expressions of pathway-related proteins were all significantly rose/increased/upregulated (P<0.05). Compared with the model group, the histopathological changes in the hippocampal/cortical tissues of rats in all curcumin dosage groups were alleviated to varying degrees, with significant improvements in all quantitative indicators (P<0.05); conversely, 2-NP significantly reversed the ameliorative effects of curcumin on these quantitative indicators (P<0.05). CONCLUSIONS Curcumin can alleviate cerebral edema and blood-brain barrier damage, reduce neuroinflammation, inhibit cell apoptosis and pyroptosis, and thereby alleviate neuronal injury in neonatal rats with bacterial meningitis. The underlying mechanism may be related to the inhibition of the STAT1/NLRP3 signaling pathway.

To investigate the clinical characteristics and prognosis of extracranial malignant rhabdoid tumor (eMRT) in children, and to provide a reference for the clinical treatment of this disease. A retrospective analysis was performed on the clinical data of children with newly diagnosed eMRT who were admitted and treated in the Department of Pediatric Oncology, Beijing Children's Hospital Affiliated to Capital Medical University, from March 2009 to December 2024. The clinical characteristics were summarized, and survival analysis and prognostic risk factor analysis were conducted. A total of 43 children with eMRT were included in this study, the median age at diagnosis of all patients was 20 months (range: 2-138 months). Among them, 24 cases were malignant renal rhabdoid tumors and 19 cases were extracranial, extrarenal rhabdoid tumors. Of the 43 children, 23 cases (53.5%) were complicated with distant metastasis. Twenty-nine (67.4%) underwent primary tumor resection. Among the children, 24 (55.8%) underwent gross total resection (GTR), 5 (11.6%) partial resection, and 14 (32.6%) biopsy only. Their 3-year overall survival (OS) rates were 40.8%, 35.3%, and 33.3%, respectively ( Children with eMRT have an overall poor prognosis. A diagnostic age < 12 months is an independent risk factor for higher mortality in these children. Further large-scale, long-term follow-up studies are needed to explore the prognostic factors of this disease.

With the increasing demand for dynamic,real-time and rapid qualitative analysis of chemical composition in areas such as emergency response and space exploration,chip-scale mass spectrometers have attracted significant attention.These devices are expected to drive the integration of mass spectrometry with micro/nano-fabrication and intelligent sensing technologies,fostering profound innovation and breakthroughs in analytical chemistry.As an excellent mass analyzer,the ion trap exhibits numerous advantages,and its miniaturization creates favorable conditions for the high-density integration of miniature mass spectrometers.However,the reduction in ion storage capacity may compromise its sensitivity and dynamic range,rendering the study of ion unidirectional ejection in highly miniaturized ion traps of significant practical importance.In this work,a research was conducted on achieving efficient ion unidirectional ejection while maintaining high mass resolution in the extremely miniature hyperbolic linear ion trap(M-HLIT)with a field radius of 1 mm,and an electric field compensation method was proposed,which combined asymmetric electrode stretching and unbalanced RF voltage to achieve high-precision optimization of the electric field composition.Simulations showed that in an ideal structure,this method achieved 100%unidirectional ejection efficiency with the mass resolution of 518,significantly outperforming traditional asymmetric structure method(365)and unbalanced voltage method(321).Following the introduction of ion ejection slots,further optimization through bidirectional stretching and electrical parameters improved the resolution to 790 while maintaining a unidirectional ejection efficiency of 93%.This method eliminated the requirement for additional excitation voltage,offering an ideal solution for the miniature mass analyzer with high detection performance of chip-level mass spectrometers.

Dent disease is a rare X-linked recessive renal tubular disease characterized by low molecular weight proteinuria,hypercalcemia and nephrocalcinosis. It is also a major cause of tubular proteinuria in children. According to different causative genes,Dent disease can be divided into three types:type 1 is caused by mutations in the CLCN5 gene,accounting for about 60%-70%;type 2 is caused by mutations in the OCRL gene,accounting for about 15%-20%;type 3 has a similar clinical phenotype but no known pathogenic gene mutations. CLCN5 encodes the voltage-dependent 2Cl -/1H +exchange channel CIC-5,which is involved in proximal renal tubule endocytosis. Its mutations can cause a variety of proximal tubular dysfunction symptoms,mainly including low molecular weight proteinuria. The use of gene detection technology has resulted in an increase in reports on Dent disease year after year. At present,the specific mechanism underlying Dent disease remains unknown. This article reviews the research progress of CLCN5,hoping to provide new insight for the mechanism research of CLCN5 and the specific treatment of Dent disease type 1.

BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.

As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

Acute lung injury (ALI) is one of the most common and critical diseases in clinical practice, with extremely high morbidity and mortality, seriously threatening human life and health. The pathogenesis of ALI is complex, in which the inflammatory response is a key factor. Studies have shown that NOD-like receptor protein 3 (NLRP3) inflammasomes are involved in ALI through mechanisms such as inflammation induction, increased microvascular permeability, recruitment of neutrophils, oxidative stress, and pyroptosis, playing a key role in the occurrence and progression of ALI. Therefore, regulating NLRP3 inflammasomes and inhibiting the release of inflammatory factors can alleviate the damage in ALI. At present, ALI is mainly treated by mechanical ventilation and oxygen therapy, which have problems such as high costs and poor prognosis. In recent years, studies have shown that traditional Chinese medicine (TCM) can reduce the inflammatory response and the occurrence of oxidative stress and pyroptosis by regulating the NLRP3 inflammasome, thus alleviating the damage and decreasing the mortality of ALI. Based on the relevant literature in recent years, this article reviews the research progress in TCM treatment of ALI by regulating NLRP3 inflammasomes, discusses how NLRP3 inflammasomes participate in ALI, and summarizes the active ingredients, extracts, and compound prescriptions of TCM that regulate NLRP3 inflammasomes, aiming to provide new ideas for the clinical treatment of ALI and the development of relevant drugs.
