BACKGROUND:With the development of the aging trend of society,the incidence of femoral neck fractures is increasing.Currently,the preferred surgical treatment is cannulated screw internal fixation.However,post-surgical femoral neck shortening occurs in some cases,resulting in impaired hip functionality.OBJECTIVE:To investigate the incidence of femoral neck shortening following the use of half-threaded cannulated screws for internal fixation in patients with femoral neck fractures,to analyze the effect on hip function,and to identify factors contributing to neck shortening.METHODS:A retrospective analysis was conducted on the medical records of 102 patients treated with half-threaded cannulated screws in an inverted triangle setup for femoral neck fractures at Affiliated Hai'an Hospital of Nantong University from January 2016 to January 2021.This group included 36 males and 66 females at the mean age of(57.2±7.7)years,with 34 cases of Garden type Ⅰ and Ⅱ fractures and 68 of Garden type Ⅲ and Ⅳ fractures.The mean bone mineral density value T was-2.8 SD.The Harris score was used to evaluate the hip function.During the follow-up period,the occurrence of femoral neck shortening was determined using X-ray imagery,and the factors influencing this shortening were examined using both univariate and multivariate regression analyses.RESULTS AND CONCLUSION:(1)Among the 102 patients with femoral neck fractures,30 patients developed femoral neck shortening,accounting for 29.4％.72 patients had no femoral neck shortening(70.6％).(2)The Harris score for patients experiencing neck shortening was significantly lower than that for patients without shortening(P＜0.05).(3)The study identified several factors associated with femoral neck shortening following the internal fixation of femoral neck fractures included age,gender,bone mineral density value T,preoperative Garden classification,and quality of reduction.These factors not only affect the shortening of the femoral neck after surgery,but are also directly related to the functional performance of the patient's hip joint.(4)Femoral neck shortening after surgery for femoral neck fracture is associated with various clinical parameters,especially the patient's age,gender,bone mineral density,preoperative classification,and accuracy of reduction during surgery.

To thoroughly implement the strategic deployment outlined in the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine regarding research on dominant diseases of traditional Chinese medicine and to uphold the development philosophy of equal emphasis on traditional Chinese medicine and western medicine，the China Association of Chinese Medicine has fully played a leading academic role by systematically organizing and conducting a series of academic youth salons on clinical dominant diseases of traditional Chinese medicine. On September 13，2024，the 36^th Youth Salon on Clinical Dominant Diseases was successfully held in Nanjing，focusing on the advantages of traditional Chinese medicine and the integrative traditional Chinese medicine and western medicine in the diagnosis and treatment of erectile dysfunction （ED）. The conference brought together leading experts from traditional Chinese medicine，western medicine，and interdisciplinary fields，facilitating in-depth multidisciplinary discussions that led to key consensus on optimizing traditional Chinese medicine treatment protocols for ED，researching and developing new drugs of traditional Chinese medicine，and advancing interdisciplinary development in traditional Chinese medicine. This salon systematically sorted out the clinical strengths and distinctive features of traditional Chinese medicine in the diagnosis and treatment of ED. Based on current research foundations and clinical needs，it identified key directions for future scientific layout and scientific research tackling： （1） Standardization of syndrome differentiation system of traditional Chinese medicine for ED. （2） Optimization and standardization of intervention methods of integrated traditional Chinese medicine and western medicine. （3） High-quality clinical research guided by evidence-based medicine. （4） In-depth analysis of the pharmacological mechanisms of traditional Chinese medicine in the treatment of ED. （5） Clinical translation and application promotion of new drugs of traditional Chinese medicine. （6） Interdisciplinary integration and innovation in traditional Chinese medicine. For each research direction，key focus areas，expected objectives，and clinical value were further refined，along with the establishment of a scientifically sound priority funding level evaluation system. Therefore，building on the series of salons on the ED-focused dominant diseases of traditional Chinese medicine，this paper provides standardized guidance for clinical practice of traditional Chinese medicine in ED management，effectively contributing to the high-quality development of traditional Chinese medicine. 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 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.

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 investigate the effects of Xuebijing injection on gut microbiota and intestinal mechanical barrier in mice with lipopolysaccharide (LPS)-induced sepsis, and analyze the potential mechanism by which Xuebijing injection protects gastrointestinal tract.Methods:Twenty-four healthy and clean grade male C57BL/6N mice were divided into four groups, control group, LPS group, LPS+ 5 μl/g Xuebijing injection group (5 μl/g Xuebijing injection group), and LPS+ 10 μl/g Xuebijing injection group (10 μl/g Xuebijing injection group), with six mice in each group. A mouse model of sepsis was established by intraperitoneal injection of mice with 10 μg/g LPS. At 0 and 12 h after successful modeling, the mice were intraperitoneally injected with 5 or 10 μl/g Xuebijing injection. Blood, ileum, and colon fecal samples were collected 12 h after the second administration. ELISA was used to detect the levels of diamine oxidase (DAO), D-blood lactic acid (D-Lac), TNF-α, and IL-6. HE staining was used to observe the local ileum damage, and Chiu′s score was used to evaluate the degree of intestinal tissue damage. Immunohistochemical staining and Western blot were used to detect the expression of Claudin-1, Occludin, and zona occludins-1(ZO-1) in ileum tissues, followed by semi quantitative analysis. One-way analysis of variance was used for intergroup comparisons, and LSD or Tamhane′s T2 test was used for pairwise comparisons based on the homogeneity of variance. The diversity and species composition of mouse fecal microbiota, and the differences among groups were analyzed using 16S rRNA sequencing.Results:The levels of DAO, D-Lac, TNF-α, and IL-6 in the LPS group were higher than those in the control group (all P<0.000 1). After the intervention with Xuebijing injection, the levels of DAO, D-Lac, TNF-α, and IL-6 decreased (all P<0.05) and showed no significant differences with those in the control group (all P>0.05). Besides, 10 μl/g Xuebijing injection was more effective than 5 μl/g Xuebijing injection in reducing the concentrations (all P<0.05). Chiu′s score was higher in the LPS group than in the control group and the 10 μl/g Xuebijing injection group (both P<0.05). Western blot showed that the expression levels of Occludin, Claudin-1, and ZO-1 in the LPS group were lower than those in the control group (all P<0.01), and Xuebijing injection intervention significantly increased the expression levels of these proteins in a dose-dependent manner as compared with the LPS group (all P<0.000 1). Apart from the expression level of ZO-1, which showed no significant difference between the two Xuebijing injection groups ( P>0.05), the results of immunohistochemical staining were consistent with those of Western blot. The 16S rRNA sequencing results showed that there were differences in the Alpha and Beta diversity indices, and the composition and structure of gut microbiota among the four groups. The structure of gut microbiota in the mice treated with Xuebijing injection was similar to that in the mice of the control group and it was in a dose-dependent manner. Wilcoxon rank sum test showed that there were statistically significant differences in six gut microbiota groups at the phylum level, and 32 gut microbiota groups at the genus level among the mice of four groups (all P<0.05). Conclusions:Xuebijing injection can provide protective effects on the gastrointestinal tract by protecting the structure of gut microbiota and intestinal barrier function, and the protective effect is somewhat correlated with the drug dosage.
