OBJECTIVE To extract the-SH active fractions(SHF)from Bubali Cornu(water buffalo horn)and evaluate its an-tipyretic activity.METHODS SHF was extracted from Bubali Cornu by SDS-DTT,and the content of native thiols(-SH)was deter-mined by Ellman reagent method.SHF was identified based on nano LC-MS/MS technology.Evaluation of antipyretic activity of SHF was based on LPS-induced fever rat model.The levels of PGE2,IL-1β,and TNF-α in plasma as well as the levels of cAMP,PGE2,and TNF-α in the hypothalamus were measured by ELISA kits.An untargeted metabolomics approach was used to further investigate the intervention of SHF on plasma metabolites in febrile rats.RESULTS SDS-DTT could effectively extract SHF from Bubali Cornu,in which the main components were type Ⅰ,type Ⅱ keratins and keratin-associated proteins,which were rich in Cys,and the ratio of-SH to protein in SHF was increased about 20 times more than that of traditional decoction.SHF could significantly decrease(P＜0.01)the body temperature which lasted for 4.5 hours.SHF could also significantly decrease the levels of PGE2,IL-1β,TNF-α and cAMP in plasma and hypothalamic.A total of 137 potentially differential metabolites were identified from plasma samples of the control and model groups,of which 31 metabolites could be dialed back after SHF administration,including lysophosphatidic acid,phosphatidyli-nositol,phosphatidic acid,triglycerides,phosphatidylcholine and so on,which were mainly involved in the glycerophospholipid meta-bolic pathway.CONCLUSION SHF has precise antipyretic effect,and the dosage of 1/10 of the aqueous extract can show its com-parable antipyretic effect,which provides the direction and basis for the basic research on the antipyretic efficacy of Bubali Cornu.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Detailed characterizations of genomic alterations have not identified subtype-specific vulnerabilities in adult gliomas. Mapping gliomas into developmental programs may uncover new vulnerabilities that are not strictly related to genomic alterations. After identifying conserved gene modules co-expressed with EGFR or PDGFRA (EM or PM), we recently proposed an EM/PM classification scheme for adult gliomas in a histological subtype- and grade-independent manner. By using cohorts of bulk samples, paired primary and recurrent samples, multi-region samples from the same glioma, single-cell RNA-seq samples, and clinical samples, we here demonstrate the temporal and spatial stability of the EM and PM subtypes. The EM and PM subtypes, which progress in a subtype-specific mode, are robustly maintained in paired longitudinal samples. Elevated activities of cell proliferation, genomic instability and microenvironment, rather than subtype switching, mark recurrent gliomas. Within individual gliomas, the EM/PM subtype was preserved across regions and single cells. Malignant cells in the EM and PM gliomas were correlated to neural stem cell and oligodendrocyte progenitor cell compartment, respectively. Thus, while genetic makeup may change during progression and/or within different tumor areas, adult gliomas evolve within a neurodevelopmental framework of the EM and PM molecular subtypes. The dysregulated developmental pathways embedded in these molecular subtypes may contain subtype-specific vulnerabilities.

Objective:To explore the effect of early essential newborn care technology during cesarean section on early health outcomes of mothers and infants and breast feeding.Methods:This study was a randomized controlled study. From October 2020 to August 2021, 104 delivery women and their newborns who were scheduled for full-term cesarean section in Peking University First Hospital were selected as the study subject. The subjects were randomly divided into control group and intervention group, 52 cases in each group. The control group received routine nursing of the newborn after cesarean section, while the intervention group received early essential newborn care technology after cesarean section. The amount of postpartum hemorrhage, hospital stay, Apgar score at one and five minutes after birth, the incidence of abnormal conditions within 90 minutes after birth, the time of umbilical cord shedding, the time of the first feeding sign of the newborn, the success rate of early initiation of breastfeeding and the implementation of breast feeding at discharge were compared between the two groups.Results:There was no statistical difference between the two groups in the amount of postpartum hemorrhage within two hours, the amount of postpartum hemorrhage within two to 24 hours and the number of days in hospital ( P>0.05) . There was no statistical difference between the two groups in Apgar scores at one and five min after birth ( P>0.05) . There was no statistical difference between the two groups in the occurrence of re-attraction, respiratory abnormalities, resuscitation, Neonatal Intensive Care Unit (NICU) transfer and other abnormalities within 90 minutes after birth ( P>0.05) . There was no statistical difference in the time of umbilical cord shedding between the two groups ( P>0.05) , and no umbilical infection occurred. The first foraging reflex in the intervention group was earlier than that in the control group, and the success rate of early initiation of breastfeeding was higher than that in the control group, and the differences was statistically significant ( P<0.05) . There was no statistical difference in the implementation of breast feeding between the two groups at discharge ( P>0.05) . Conclusions:It is safe and feasible to implement early essential newborn care technology during cesarean section, and it can effectively promote early initiation of breastfeeding, which is of great significance for breast feeding and has the value of clinical promotion.

Objective: To compare the therapeutic efficacy between warm needling moxibustion and electroacupuncture (EA) in the treatment of simple obesity due to yang deficiency of the spleen and kidney. Methods: Seventy patients with simple obesity due to yang deficiency of the spleen and kidney were randomly divided into a warm needling moxibustion group and an EA group, with 35 subjects in each group. Same major acupoints were selected for the two groups, including Shuifen (CV 9), Guanyuan (CV 4), Daheng (SP 15), Shuidao (ST 28), Shousanli (LI 10), Zusanli (ST 36), Sanyinjiao (SP 6) and Taixi (KI 3). The warm needling moxibustion group received warm needling moxibustion, while the EA group received EA treatment. The interventions were performed once every other day, with 15 treatments as one course. The therapeutic efficacy, body weight and body mass index (BMI) were then observed and compared. Results: The total effective rate in the warm needling moxibustion group was 85.7％ versus 77.1％ in the EA group, and the between-group difference was statistically significant (P<0.05). The warm needling moxibustion was remarkably superior to the EA in weight loss and lowering BMI, both with statistical significance (P<0.05, P<0.01). At the three-month follow-up, the body weight and BMI further decreased in the warm needling moxibustion group (both P<0.05), and the levels were lower than those in the EA group (P<0.05, P<0.01). Conclusion: Warm needling moxibustion can produce reliable and consistent efficacy in the treatment of simple obesity due to yang deficiency of the spleen and kidney. Compared with EA, warm needling moxibustion shows advantage in both short-term and long-term efficacies, and thus is worth promotion in clinical practice.

Objective To investigate the clinical features of patients with acute ST-segment elevation myocardial infarction (STEMI) comorbid with diabetes mellitus (DM) and to analyze the prognosis within 12 months after primary percutaneous coronary intervention (pre-PCI). Methods A total of 375 STEMI patients were divided into the diabetes group (n=140) and the normal blood glucose group(n=235) according to whether they met the diagnostic criteria of DH. The clinical data,characteristics of coronary artery lesions,type of stent implant,rate of coronary slow flow or no-reflow after pre-PCI, and the prognosis within 12 months after PCI of the two groups were investigated.Results Patient in the diabetes group presented with higher mean age ,higher comorbid rates of hypertension , hyperlipidemia and heart function of Killip class Ш and above than patients in the normal blood glucose group (all P<0.05). patients in the diabetes group had higher rates of slow reflow /no-reflow after PCI(12.9% vs.5.5%,P=0.013),higher percentages of 3-ressel disease(40.7% vs. 28.9%,P=0.019)and lef t main lesions(13.6% vs. 7.2%,P=0.044). The in-hospital mortality rates(6.4% vs.1.7%,P=0.020),revascularization rates within 12 months(7.9% vs.0.9%,P=0.001)and incidence of heart failure(7.9% vs. 2.6%,P=0.017)were all higher in the diabetes group. Conclusions STEMI patients comorbid with DM were relatively older, had higher comorbidities of hypertension,hyperlipidemia, three-vessel disease, left main coronary lesions and higher mortality during hospitalization. No significant increase in cardiac death and recurrent myocardial infarction were deserved during the follow-up period. These patients may benefit more from early intervention.

OBJECTIVES: To observe the preventive and therapeutic action of Yuyin Ruangan Granule (YRG, Traditional Chinese Medicine) in hepatic fibrosis rats model and its effect on transforming growth factor-β1 (TGF-β1) expression. METHODS: The Wistar rats were randomly divided into 6 group (=10), and the model of hepatic fibrosis rats was established by subcutaneous injected with carbon tetrachloride (CCL4), fed on high-fat diet and 20% ethanol for 6 weeks, to survey the effect and mechanism of YRG preventing hypatic fibrosis by detecting liver function (the activity of alanine aminotransferase(ALT), aspartate aminotransferase(AST), etc.) of liver fibrosis rats, liver fibrosis indicators (hyaluronic acid, Ⅲ procollagen, type IV collagen, laminin and hepatic pathology, etc.), and TGF-β1 expression in liver tissue after 6 weeks treated with YRG through intragastric administration (q. d.). RESULTS: At the 7 week, fibrotic lesions appears distinctly in liver tissue of model group compared with control group (<0.01), YRG of 6.2~28.8 g/kg could significantly decrease hepatic index, ALT and AST activities, content of hyaluronic acid(HA), Ⅲ procollagen (PCⅢ), type Ⅳ collagen(C-Ⅳ), laminin (LN) in serum, relieve liver fibrosis pathological changes and inhibit TGF-β1 expression in fibrotic liver tissue (<0.05, <0.01). CONCLUSIONS YRG has significantly preventive effects on liver fibrosis rats model, and it may be one of its mechanisms to inhibit expression of TGF-β1.
