OBJECTIVE: To investigate the prenatal manifestation and genetic basis for two fetuses suspected for Osteocraniostenosis (OCS). METHODS: Two fetuses undergoing invasive prenatal diagnosis at Cangzhou People's Hospital in April and August 2021 for short long bones and abnormal skull morphology were selected as the study subjects. Clinical data were collected and analyzed. Genomic DNA was extracted from amniotic fluid and peripheral blood samples of the two couples. Candidate variants were validated by Sanger sequencing. Literature was retrieved from CNKI, Wanfang Data Knowledge Service Platform and PubMed using keywords including "FAM111A gene", "gracile bone dysplasia", "FAM111A" and "osteocraniostenosis" from January 1, 2000 to June 30, 2025. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: K2020-049). RESULTS: Fetus 1 was found to have short limbs, abnormal skull morphology and shallow cerebral sulci. Fetus 2 showed short limbs, irregular skull halo, prominent forehead and bilateral frontal narrowing. Trio-WES revealed that fetus 1 has carried a heterozygous missense variant c.1582G>C (p.Asp528His) in exon 4 of the FAM111A gene, which was unreported previously. Fetus 2 has harbored a heterozygous in-frame deletion c.1020_1022delTTC (p.Ser343del) in exon 6 of the FAM111A gene, which has been recorded as likely pathogenic by the ClinVar and HGMD databases. Sanger sequencing confirmed that the parents of both fetuses were wild-type for the variant sites. A total of 9 previously reported patients with FAM111A-related gracile bone dysplasia/OCS from 4 publications were retrieved. The main clinical features included intrauterine growth restriction, hypomineralized skull, gracile long bones with narrow medullary cavities and characteristic facial anomalies, which were in large in keeping with the prenatal features of the two fetuses. CONCLUSION Both fetuses were diagnosed with FAM111A-related OCS based on the characteristic prenatal findings and identification of the FAM111A variants. Above finding expanded the phenotypic spectrum of FAM111A-associated disorders and provided clues for the prenatal diagnosis and genetic counseling.

It serves as a valuable reference for national scientific and technological strategic layout， research and development decision-making in new drugs of traditional Chinese medicine，research topic planning，and clinical guideline formulation.

Chronic post-surgical pain (CPSP) is a common long-term complication following lung surgery. Its high incidence significantly impacts patients’ quality of life and functional recovery, and imposes a substantial socioeconomic burden. This consensus aims to systematically establish a standardized integrated Chinese and Western medicine diagnostic and treatment framework for chronic post-lung surgery pain (CPLSP). Based on the latest domestic and international evidence-based medical research and multidisciplinary clinical experience, the working group comprehensively elaborates on core issues regarding CPLSP, including its definition, epidemiology, pathogenesis, clinical assessment, Western medical treatment, traditional Chinese medicine (TCM) treatment, and integrated strategies. The consensus emphasizes a patient-centered approach, adhering to the principles of multimodality, individualization, and stepwise management, highlighting the synergistic advantages of integrating Chinese and Western medicine throughout the entire perioperative management cycle encompassing "perioperative anti-inflammation, acute analgesia, and chronic rehabilitation." Through systematic literature retrieval and evidence integration, a total of 9 core recommendations were established to provide scientifically sound and clinically practical guidance.

Objective To investigate the impact of red blood cell suspension infusion across various perioperative periods on patients with valvular heart disease. Methods The patients with valvular heart disease admitted to Tianjin Chest Hospital from 2018 to 2020 were selected. Based on the timing of perioperative red cell suspension infusion, patients were categorized into three groups: a group 1 receiving intraoperative red cell suspension infusion, a group 2 receiving red cell suspension infusion within 24 hours after entering the ICU, and a group 3 receiving red cell suspension infusion at both time points. The laboratory results, perioperative blood component infusion volume, and other relevant parameters were retrospectively analyzed. After propensity score matching, the differences in different variables among the three groups were compared. Results After propensity score matching, 102 patients were enrolled, including 52 males and 50 females, with an average age of (61.74±10.58) years. There were 34 patients in each group. The preoperative hemoglobin (Hb) value of the group 2 was significantly higher than that of the group 1 and the group 3, and the amount of red cell suspension and autoblood transfusion was the lowest (P<0.05). Group 1 had the highest postoperative Hb, as well as the highest Hb and hematocrit (HCT) levels within 24 hours post-surgery (P<0.05). The group 1 had the lowest plasma, platelet and cryoprecipitate infusion volumes, and the shortest cardiopulmonary bypass time, aortic occlusion time, postoperative ICU stay and hospital stay, and the least blood loss and total drainage volume (P<0.05). The difference between postoperative and preoperative Hb (△Hb1) was highest in group 1 (P<0.05). Conclusion For patients with valvular heart disease, intraoperative-only infusion of red blood cell suspension is associated with a better prognosis at discharge and during follow-up.

OBJECTIVE: To carry out genetic testing on two fetuses with prenatal ultrasound finding of polydactyly and renal abnormalities to determine the underlying causes. METHODS: Two fetuses with structural abnormalities detected by prenatal ultrasound at Cangzhou People's Hospital in 2021 were selected as the study subjects. Genomic DNA was extracted from the muscle tissue of the abortus and peripheral blood samples from both parents. Whole-exome sequencing (WES) was conducted on the trio to detect the genetic variants. Quantitative PCR was used to validate the exonic deletions. This study has been approved by the Ethics Committee of Cangzhou People's Hospital (Ethics No.K2020-049). RESULTS: Prenatal ultrasound revealed postaxial polydactylies of fingers and toes and slightly enlarged kidneys with increased echogenicity in fetus 1, along with polydactyly of both hands, enlarged kidneys, and enhanced echogenicity of renal parenchyma in fetus 2. Trio-WES analysis revealed that fetus 1 has harbored a pathogenic c.1339G>A variant of the BBS1 gene, along with a heterozygous 426 bp deletion in the 11q13.2 region, which was unreported previously. The deletion has involved exons 10 and 11 of the BBS1 gene. The two variants were inherited from its mother and father, respectively. Fetus 2 was found to harbor a pathogenic c.539G>A variant and a likely pathogenic c.49G>A variant of the BBS10 gene, which were inherited from its mother and father, respectively. The c.49G>A variant has not been documented in databases and the literature. CONCLUSION Two rare fetuses with Bardet-Biedl syndrome have been diagnosed. Above finding has expanded the mutational spectrum of this syndrome and has important implications for genetic counseling for the affected families.

Objective:To evaluate the safety of neoadjuvant therapy with pembrolizumab combined with 5-fluorouracil (5-FU) and cisplatin in patients with advanced temporal bone squamous cell carcinoma (TBSCC), and its impact on tumor response rate and disease-free survival (DFS).Methods:This prospective, single-arm, open-label clinical study enrolled patients with advanced (Stage Ⅲ/Ⅳ) TBSCC from Sun Yat-sen Memorial Hospital. Patients received 2-3 cycles of neoadjuvant therapy with pembrolizumab, 5-FU, and cisplatin, followed by definitive surgery. Postoperatively, patients received 6 cycles of pembrolizumab combined with radiotherapy. The primary endpoint was the 2-year disease-free survival (DFS) rate. Secondary endpoints included objective response rate (ORR) and safety indicators. Survival analysis was performed using the Kaplan-Meier method. Adverse events (AE) were assessed using the National Cancer Institute′s Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Statistical analyses were conducted using SPSS software, version 22.0.Results:From August 2021 to April 2024, 16 patients with advanced TBSCC were enrolled (13 males and 3 females), with a median age of 54 years and a median follow-up time of 2.32 years. Following neoadjuvant therapy, the objective response rate (ORR) was 64.3% (9/14), and the disease control rate (DCR) was 92.9% (13/14). The 2-year DFS rate was 86.6%. Common treatment-related adverse events (TRAE) included leukopenia (56.3%, 9/16), nausea and vomiting (50.0%, 8/16), diarrhea, oral mucositis, and elevated liver function tests (25.0%, 4/16). One patient (6.25%) experienced a grade 3 adverse event.Conclusion:Neoadjuvant pembrolizumab-chemotherapy significantly enhances objective response rate and disease-free survival in advanced TBSCC.

Objective To investigate the effects and potential mechanism of tuina on pain and depressive behaviors in rats with neuropathic pain(NP).Methods A total of 102 SD rats were randomly divided into blank group,sham-operation group,model group,tuina group,inhibitor group and inhibitor+tuina group,with 17 rats in each group.The NP model was established by chronic constriction injury of the sciatic nerve.Starting from the 8th day post-operation,the rats underwent a 14-day tuina intervention and stereotactic injection of the SIRT1 inhibitor EX-527(20 μg/μL,0.5 μL)into the hippocampal CA1 region.Pain behaviors were assessed using the mechanical withdrawal threshold test one day before operation and on days 7,14 and 21 post-operation.Depressive behaviors were evaluated using the forced swimming test and sucrose preference test.Nissl staining was employed to observe neuronal morphology and quantity in the hippocampal tissue,while Golgi staining was used to examine dendritic spine density,hippocampal expression of SIRT1/BDNF/TrkB signaling pathway related protein and mRNA were analyzed using immunofluorescence,Western blot and RT-qPCR.Results Compared with the sham-operation group,the model group showed a significant decrease in mechanical withdrawal threshold(P<0.001),prolonged immobility time in the forced swimming test and reduced sucrose preference(P<0.001)on days 7,14 and 21 post-operation;the morphology of hippocampal CA1 neurons was abnormal,with a significant decrease in the number of Nissl positive cells(P<0.001)and a significant decrease in dendritic spine density(P<0.001);the expressions of SIRT1,BDNF and TrkB in dentate gyrus of the hippocampus were significantly reduced(P<0.01,P<0.001),and the protein and mRNA expressions of SIRT1,BDNF and TrkB were significantly reduced(P<0.001).Compared with the model group,the tuina group showed a significant increase in mechanical withdrawal threshold(P<0.01,P<0.001)on days 14 and 21 post-operation,shortened immobility time in the forced swimming test(P<0.01,P<0.001)and increased sucrose preference(P<0.001);the hippocampal CA1 neuronal morphology was improved,with significantly increased Nissl positive cells(P<0.001)and dendritic spine density(P<0.001);the expressions of SIRT1,BDNF and TrkB in dentate gyrus of the hippocampus significantly increased(P<0.01,P<0.001),and the protein and mRNA expressions of SIRT1,BDNF and TrkB were significantly increased(P<0.001).The beneficial effects of tuina were significantly inhibited when the SIRT1 inhibitor EX-527 was used.Conclusion Tuina may alleviate pain and depressive behaviors in NP rats by activating the SIRT1/BDNF/TrkB signaling pathway and improving hippocampal neuronal structural plasticity.

Diabetes mellitus is a metabolic disease characterized by chronic hyperglycemia,which long-term loss of control can lead to complications of blood vessels of heart,renal and other multi-system,and even threaten the patient's life.Monitoring for blood glucose is crucial for adjusting treatment and preventing complications.Traditional invasive glucose monitoring technology requires frequent blood collection,which not only leads to significant pain in patients,but also poses the risk of infection at the puncture site,coupled with the reduced compliance brought about by cumbersome operation,which seriously restricts the effectiveness and continuity of blood glucose management.The non-invasive monitoring technique for blood glucose can enhance frequency of monitoring,and comfort level through optical method,biosensing method,etc.,which has key values in optimizing glycemic control,reducing risk of complications,and decreasing medical cost.It is becoming a hot point of research.This review summarized a noninvasive monitoring technique system included sample analysis method,optical method and physiological process-based method,which analyzed principles,advantages,and limitations of its development of each detection method.The review also concluded the challenges of noninvasive monitoring technique for blood glucose in some aspects included overcoming individual differences,enhancing precision of measurement,and improving accuracy and stability.In addition,it proposed some developing directions of noninvasive monitoring technique in future,such as continuous monitoring equipment with low cost,establishment of standardized database,and individual validation,so as to promote implementation of noninvasive monitoring technique for blood glucose,and realize accurate management for diabetes mellitus.
