Objective:To investigate the clinical, radiological and histological features of intraosseous hibernoma.Methods:Two cases of intraosseous hibernoma diagnosed in the Department of Pathology, the Sixth People′s Hospital Affiliated to Shanghai Jiaotong University School of Medicine from 2020 to 2023 were analyzed. Related literature was also reviewed.Results:One case was a 44-year-old female with abnormal signals in the proximal right femur revealed by MRI, who underwent curettage of the lesion. The other case was a 41-year-old female with an occupying lesion in the second sacral vertebrae revealed by CT and MRI, who underwent CT-guided biopsy. Microscopically, both tumors were composed of large polygonal cells, with finely vacuolated cytoplasm and distinct cell membranes and variably admixed mature adipose cells or hematopoietic components within the stroma. Nuclei were small, centrally or paracentrally situated and displayed prominent scalloping. Nuclear atypia was absent. A relatively clear tumor boundary could be observed in one case. Immunohistochemical staining showed that tumor cells were positive for S-100 protein, while negative for keratin, CD68, H3F3A, and Brachyury.Conclusions:Intraosseous hibernoma is extremely rare and tends to affect middle-aged and elderly patients. It most frequently occurs in the spine and pelvis. It needs to be differentiated from metastatic cancer, Erdheim-Chester disease, intraosseous lipoma with necrosis, and benign notochordal cell tumor. Increasing awareness of it helps to avoid missed diagnoses or excessive treatment due to misdiagnosis.

Objective To explore the application effect of traditional Chinese medicine rolling egg therapy in the treatment of infantile diarrhea.Methods A retrospective analysis was conducted on the clinical data of children with diarrhea in Dongguan People's Hospital from April 2022 to April 2024.According to the treatment methods,they were divided into the control group and the combination group.The control group was treated with western medicine,while the combination group was combined with traditional Chinese medicine rolling egg therapy on the basis of the control group.7 d was a course of treatment,and a total of 2 courses of treatment was conducted.The clinical efficacy was evaluated,and the durations of clinical symptom changes after treatment were compared.The intestinal flora,immune function[immunoglobulin (Ig) A,IgG,IgM]and inflammatory factors[interleukin (IL)-6,IL-17,tumor necrosis factor (TNF) α]were observed before and after treatment.The treatment safety was analyzed,and the recurrence within 6 months of follow-up was counted.Results A total of 180 patients were included in the study,with 106 in the control group and 74 in the combination group.The total effective rate of the combination group was higher than that of the control group (P<0.05).After treatment,the time to stop diarrhea,reduce fever and change stool properties to normal in the combination group was lower than that in the control group (P<0.05);the number of Bifidobacteria and Lactobacilli in both groups was higher than that before treatment,and the number of combination group was higher than that of the control group (P<0.05);the number of Enterococcus faecalis and the levels of TNF-α,IL-6 and IL-17 were lower than those before treatment in both groups,and these in the combination group were lower than those in the control group (P<0.05);the levels of IgA,IgG and IgM were higher than those before treatment in the combination group (P<0.05),and the IgA level was significantly higher than that of the control group (P<0.05).At 6 months,the recurrence rate of the combination group was lower than that of the control group (P<0.05).Conclusion Traditional Chinese medicine rolling egg therapy combined with western medicine is effective in the treatment of children with diarrhea,and its mechanism may be related to the improvement of immune function,inflammatory response and intestinal flora.

Background:Intestinal microbiota dysbiosis and impaired intestinal barrier,leading to bacterial translocation,are involved in acute pancreatitis(AP)exacerbation.Antimicrobial peptides participate in the regulation of intestinal microbiota,yet their changes and roles in the course of AP are unclear.Aims:To investigate the dynamic changes and significance of antimicrobial peptides in the ileum and pancreas among three classical AP models.Methods:Three AP mouse models were established by using cathelicidin plus lipopolysaccharide(CAE+LPS),sodium taurocholate(N-Tau)and L-arginine(L-Arg),respectively.The pathological changes of pancreatic and ileal tissues were observed and scored.Real-time PCR was applied to detect the expression levels of the proinflammatory cytokines,and antimicrobial peptides including lysozyme(LZM),secretory phospholipase A2(sPLA2),angiogenin 4(Ang4),regenerating islet-derived protein 3(REG3)family,β-defensin family,cathelicidin-related antimicrobial peptide(CRAMP),and glycoprotein 2(GP2)in ileum and/or pancreas.The association between expressions of antimicrobial peptides and the injuries of pancreas and ileum was analyzed.Results:Pancreatic and ileal injuries could be observed in all three AP models in different time points with various degrees.The pathological scores of the CAE+LPS and N-Tau models reached the highest level and then declined from 0-72 h,while those of L-Arg model progressively increased within 72 hours.Compared with the corresponding controls,the mRNA levels of LZM,sPLA2,and Ang4 in ileal tissue,and the mRNA levels of CRAMP,GP2,and β-defensins in pancreatic tissue,were generally downregulated in all three AP models(all P<0.05).CAE+LPS and N-Tau models showed a trend of initial decrease followed by partial recovery,while L-Arg model exhibited a gradual downregulation trend.The mRNA levels of REG3β and REG3γ in ileum upregulated and reached the peak at 48 h or 24 h and downregulated significantly at 72 h in all three AP models(all P<0.05);while in pancreatic tissue,both REG3β and REG3γ were generally upregulated in all three AP models(all P<0.05),but fell back in CAE+LPS and N-Tau models at 72 h.The mRNA levels of ileal β-defensins upregulated significantly in the early stage of the disease(12 h)in all three AP models(all P<0.05),and then gradually decreased.Spearman correlation coefficient analysis showed that the expressions of ileal LZM,sPLA2,and Ang4,as well as the pancreatic CRAMP,GP2,and β-defensins,were significantly negatively correlated with the pancreatic and ileal pathological scores in all three AP models(all P<0.05);but the expression of REG3β in the pancreas was significantly positively correlated with the pancreatic and ileal pathological scores(all P<0.05).Conclusions:The expressions of LZM,sPLA2,and Ang4 in the ileum,as well as the expressions of CRAMP,GP2,β-defensin family,and REG3β in the pancreas of the three classical AP models,dynamically changed with the severity of the disease.Ileal and pancreatic antimicrobial peptides may affect the injuries of pancreas and intestine during AP by regulating intestinal microbiota.

Postoperative pain seriously affects the recovery process of patients, resulting in prolonged hospital stay and increased care costs. Appropriate application of patient-controlled analgesia devices can effectively relieve perioperative acute pain. In 1994 patient-controlled analgesia began to be used in Peking Union Medical College Hospital, and the Acute Pain Service Working Group was established in 2004. With the cooperation of anesthesiologists and specialist nurses, the group jointly has implemented the whole process and standardized management based on patient-controlled analgesia, and constantly improved and innovated working methods, laying a solid foundation for the development of postoperative pain management. This paper systematically reviews and summarizes the work from the aspects of clinical focus, nursing management experience, promotion and dissemination of pain treatment concepts, and development of acute pain service model under the new situation, with the hope of providing valuable reference for comprehensively strengthening pain management in the process of diagnosis and treatment, and enhancing patients' satisfaction with perioperative analgesia services.

Objective:The clinical and molecular genetic characteristics of 46, XY disorders of sex development caused by NR5A1 gene variants in 15 cases were analyzed to improve the understanding of this disease. Methods:The clinical data of children with NR5A1 gene variants diagnosed at the Children′s Hospital Affiliated to Zhengzhou University from March 2016 to December 2021 were retrospectively analyzed. Whole exome sequencing was performed to confirm the candidate sites, and Sanger sequencing was performed for validation. The patients were treated and followed up according to their disease characteristics. Results:At the initial diagnosis, 5 of the 15 cases were raised as females and 10 as males. The gonadal tissue was testis without residual Müllerian or ooticular structure, and all had various degrees of genital abnormalities. The average EMS masculinity score was 4.8 (1~9), including micropenis (100.0%), hypospadia (86.7%), unfused scrotum (46.7%), and abnormal testicular position (60.0%), in which the hypospadias was Ⅱ°~Ⅳ°. There was no skin pigmentation in 5 patients with growth retardation. Chromosomol karyotypes were 46, XY, adrenocorticotropin and cortisol levels were normal, electrolyte levels were normal, HCG stimulation test in 5 cases had normal response, 9 cases had low response. Anti-Müllerian hormone and statin B had decreased abnormally with age. A total of 14 NR5A1 variants were detected in the 15 children, most of which occurred in exon 4, of which 9 variant loci were not included in the HGMD database as of December 2022. Conclusion:The clinical phenotype of 46, XY abnormal sexual development caused by NR5A1 gene variants is extensive, with the external genitals showing varying degrees of insufficient masculinization. Adrenal involvement is rare.

Objective:To evaluate the efficacy and safety of anaprazole (40 mg and 60 mg) and compared with rabeprazole (20 mg) in the treatment of reflux esophagitis (RE).Methods:This multicenter, randomized, double-blinded, positive drug parallel controlled study was led by the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital) and a total of 24 clinical trial institutions nationwide including the First Affiliated Hospital of Nanchang University, Yichun People′s Hospital, Meihekou Central Hospital, the First Affiliated Hospital of Gannan Medical University, and Jinhua Central Hospital, participated in this research. A total of 156 patients with RE (Los Angeles grade A to D) were enrolled and randomly divided into 3 groups, anaprazole 40 mg group, anaprazole 60 mg group and rabeprazole 20 mg group, using a random number table in a ratio of 1∶1∶1. Patients in the above 3 groups were treated with the appropriate trial medication once per day for 4 or 8 weeks. The endoscopic healing rates were evaluated by Blinded Independent Central Review (BICR) and investigators. In addition, the improvement in the severity of individual symptoms (daytime reflux, daytime heartburn, nighttime reflux, nighttime heartburn) and medication safety were also evaluated. The endoscopic healing rates and 95% confidence intervals (95% CI) at week-8 and -4 were calculated by groups, as well as the difference in the healing rates and their 95% CI among groups. The chi-square test was used for statistical analysis. Results:A total of 153 subjects were included in the full analysis set (FAS), 144 in the per-protocol analysis set (PPS) and 151 in the safety set (SS). In the FAS, after 8 weeks of treatment, the endoscopic healing rates of anaprazole 40 mg group, anaprazde 60 mg group and raberazole 20 mg group blindly assessed by BICR were 86.0% (43/50), 86.5% (45/52) and 86.3% (44/51), respectively, and the 95% CI were 76.4% to 95.6%, 77.3% to 95.8% and 76.8% to 95.7%, respectively.The endoscopic healing rates of anaprazole 40 mg group, anaprazde 60 mg group and raberazole 20 mg group blindly evaluated by investigators were 88.0% (44/50), 90.4% (47/52) and 86.3% (44/51), respectively, and the 95% CI were 79.0% to 97.0%, 82.4% to 98.4% and 76.8% to 95.7%, respectively. The endoscopic healing rates were similar among groups. In the FAS, the differences in healing rates(95% CI) assessed by BICR and investigators between anaprazole 40 mg, anaprazole 60 mg and rabeprazole 20 mg group were -0.3%(-13.7% to 13.2%), 0.6%(-12.3% to 13.6%), respectively and 1.7%(-11.3% to 14.8%), 3.9%(-8.5% to 16.3%), respectively. The results of the PPS were consistent with those of the FAS. After 8 weeks of treatment, the severity scores of individual symptoms (daytime reflux, daytime heartburn, nighttime reflux, nighttime heartburn) decreased in all groups. The differences between post-treatment and baseline in anaprazole 40 mg group, anaprazole 60 mg group and rabeprazole 20 mg group were -1.54±1.00, -1.91±1.00, -1.51±0.76, -1.45±0.71; -1.30±0.94, -1.59±0.96, -1.33±0.65, -1.42±0.60; and -1.74±0.85, -1.76±0.93, -1.45±0.66, -1.66±0.79, respectively. The incidence of treatment emergent adverse event of anaprazole 40 mg group, anaprazole 60 mg group and rabeprazole 20 mg group were 57.1% (28/49), 48.1% (25/52) and 60.0% (30/50), respectively, and the incidence of treatment related adverse event were 18.4% (9/24), 25.0% (13/52) and 24.0% (12/50), respectively. There were no statistically significant differences in the incidence of treatment emergent adverse event and treatment related adverse event among 3 groups (all P>0.05). Conclusion:The efficacy and safety of anaprazole 40, 60 mg/d, and rabeprazole 20 mg/d in the treatment of RE are comparable.

OBJECTIVE To investigate the role of the complement C3/C3aR signaling pathway in the prefrontal cortex and colon neuroglia cell interactions during meth-amphetamine(METH)addiction,to observe the effects of TLR4 inhibitors as well as complement C3 elimination on METH reward and relapse behavior,and to explore the neuroinflammatory mechanisms of complement C3 acti-vation in METH addiction.METHODS ①A 14 d and 28 d rat METH addiction model was established to observe the effects of TLR4 antagonist ibudilast 3 mg·kg-1 and 10 mg·kg-1 on self-administration,reward motivation,relapse,and natural reward behavior in METH-trained 14 d rats and the effects of 0.02 mg·kg-1 complement C3 antago-nist on self-administration behavior in METH-trained 28 d rats.② Differences in the expression of TLR4,NF-κB,GRP94,C3,cathepsin L,CD68,and GFAP in the pre-frontal cortex of each group were examined using West-ern blotting.③ In addition,the expression of ATF6 in the prefrontal cortex of each group and the effects on neuro-nal and microglia/macrophage INOS,CD206 GRP94,and complement C3/C3aR.RESULTS ① Endoplasmic reticulum stress occurred in neurons and microglia after METH exposure depending on GRP94 and unfolded pro-tein responses to the ATF6 pathway.In addition,it acti-vates the TLR4-NF-κB pathway.② Microglia with high complement C3/C3aR expression in the prefrontal cortex were recruited to synaptic pruning and phagocytic responses around neurons with high GRP94,comple-ment C3/C3aR expression and these effects were blocked by complement C3 antagonists.③ In the rec-tum,GRP94 functions as a molecular chaperone for com-plement C3 and cathepsin L.Crosstalk occurs between enteric neurons high in GRP94,complement C3,and macrophages high in C3aR,located in the submucosa,lamina propria,and muscular,respectively,and all of these effects are blocked by complement C3 antago-nists.④ Treatment with the TLR4 antagonist ibudilast inhibits self-administration,reward motivation,and cue-or METH-priming in METH-trained 14 d rats,but fails to affect natural reward behavior.Ibudilast treatment attenu-ates the TLR4-NF-κB inflammatory pathway and comple-ments C3/C3aR pathway in the prefrontal cortex.CON-CLUSION Activation of the complement C3/C3aR signal-ing pathway by TLR4-NF-κB inflammatory signaling in the prefrontal cortex mediates the METH addiction pro-cess,providing an experimental basis for the clinical treatment of METH addiction,and targeting TLR4/NF-κB inflammatory signaling and complement C3/C3aR may be a new way to intervene in METH addiction.
