Objective To establish a HPLC fingerprint identification method for the stir-frying product of Selaginella moellendorffii Hieron.Methods RP-HPLC method was performed on Zorbax C18(250 mm? 4.6 mm,5 ? m)column.The chromatographic condition was as follows:mobile phase consisting of 0.5 % acetic acid and acetonitrile,gradient elution,flow rate of 1 mL/min and detection wavelength at 260 nm and 338 nm.Results There were 12 feature peaks,which made up HPLC fingerprint pattern of stir-frying products of Selaginella moellendorffii Hieron.Conclusion The method is simple,accurate with a good repeatability,and can be used for the quality control of stir-frying product of Selaginella moellendorffii Hieron.

This patient presented with fever,seizure and bulging fontanelle when he was 6-month-old.According to the investigations,white blood cell (WBC),erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) increased significantly,and Streptococcus Pneumonia grew in both blood and cerebrospinal fluid (CSF).He responded to standard antibiotic treatment poorly even it lasted long enough.At the same time,the inflammation seemed to be over-activated,the WBC level was still elevated,high fever continued.Thus they thought of primary immunodeficiency and sent blood sample for gene panel testing (Sanger sequencing) but got negative result.At last,they added steroid together with anti-tuberculosis drug therapy,his temperature as well as the intracranial pressure became better ever since.At the age of 1 year and 1 month,he got another Streptococcus Pneumonia meningitis,while he was still on anti-tuberculosis drug therapy and tapering off steroid.At this time,he presented with coarse hair,hypohidrosis and delayed eruption of teeth,which strongly indicated Anhidrotic Ectodermal Dysplasia with Immunodeficiency (EDA-ID).NEMO is the most common gene responsible for EDA-ID and locates on X chromosome.It has a pseudogene named IKBKGP which locates downstream of NEMO.IKBKGP and NEMO share 3-10 exons with the homology of 99.8％,which makes it difficult to find out most real mutations within NEMO with Sanger sequencing.Then they performed PCR with the primer starting upstream of the shared exons.Finally,they found out the pathogenic mutation [c.505G ＞ C(p.A169P)] of NEMO,which has been reported.This finding led us to make the right diagnosis as well as the proper treatment and the prognosis for this patient.

ABSTRACT: Meningiomas are the most common primary intracranial neoplasm with diverse pathological types and complicated clinical manifestations. The fifth edition of the WHO Classification of Tumors of the Central Nervous System (WHO CNS5), published in 2021, introduces major changes that advance the role of molecular diagnostics in meningiomas. To follow the revision of WHO CNS5, this expert consensus statement was formed jointly by the Group of Neuro-Oncology, Society of Neurosurgery, Chinese Medical Association together with neuropathologists and evidence-based experts. The consensus provides reference points to integrate key biomarkers into stratification and clinical decision making for meningioma patients.
