By consulting the ancient and modern literature， the name， origin， quality evaluation， harvesting and processing methods of Curculiginis Rhizoma（CR） were systematically combed and verified， in order to provide a basis for the development and utilization of famous classical formulas containing CR. The results of herbal textual research showed that the name Xianmao was first recorded in Leigong Paozhilun， the name of CR was used in all dynasties and this name came from its efficacy and morphological characteristics， the mainstream source for CR of the past dynasties was the rhizome of Curculigo orchioides or C. capitulata， since modern times， C. orchioides has been the main source of commodities. In ancient times， most of the places of origin of the description were the western regions and southwest China， while in modern times， Sichuan and Guizhou were regarded as genuine places. Since modern times， its quality has been summarized as the best with thick roots， firm texture and black-brown surface， the harvesting and processing methods recorded in the past dynasties are mainly sun drying after harvest in the second， eighth and ninth months of the lunar calendar， and most of them are harvested in autumn and winter in modern times. In ancient times， there were many processing methods of CR， mainly in processing with rice swill， while in modern times， stir-frying with wine was the main processing method. The nature， taste， meridian tropism， functions and indications of CR are basically consistent from ancient to modern times， the taboos for taking are to avoid iron， cow's milk， and beef. Although there are some differences in the understanding of the toxicity of CR in the past dynasties， most of the materia medica are clear that it has a certain toxicity. Based on the research conclusion， it is suggested that the rhizome of C. orchioides of Lycoris family should be used as its source in the famous classical formulas， and the corresponding processing method should be selected according to the processing requirements in the formulas， while the raw products is recommended to be selected as medicine if the processing requirement is not specified.

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.

Objective To evaluate the effect of prone ventilation in children with severe pneumonia at high altitude.Methods By convenience sampling method,80 children with severe pneumonia hospitalized in intensive care department of a tertiary A children's hospital in Xining,Qinghai Province from June 2021 to June 2023 were selected as the study subjects,and the regional randomization group method was used to divide into a test group and a control group with 40 cases in each group.On the basis of routine care,the test group received prone ventilation once a day for 6 to 12 h;the control group received supine ventilation.Respiratory mechanical parameters(oxygenation index,oxygen saturation,arterial oxygen partial pressure,arterial CO2 partial pressure),mechanical ventilation duration and safety parameters(incidence of unplanned extubation,stress injury)at 6 h and 12 h of mechanical ventilation were compared.Results There were no shedding cases.The interaction between oxygenation index,blood oxygen saturation and arterial oxygen partial pressure(P＜0.05)in the 2 groups was compared(P＞0.05).The results of simple effect analysis showed that at 6 h,the oxygen saturation and oxygenation index in the test group were higher than those in the control group,and the difference was statistically significant(P＜0.05).At 12 h of mechanical ventilation,the oxygenation index,blood oxygen saturation and arterial oxygen partial pressure in the test group were higher than those in the control group,and the difference was statistically significant(P＜0.05).The time of mechanical ventilation in the test group was102.00(60.00,153.00)h and 126.00(108.00,156.00)h in the control group,and the difference was statistically significant(P=0.013).The incidence of unplanned extubation and pressure injury were compared,and the differences in 2 groups were not significant(P＞0.05).Conclusion Prone ventilation in children with severe pneumonia at high altitude is safe and feasible,which is helpful to improve the respiratory function and shorten the time of mechanical ventilation.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

The number of patients with neoadjuvant chemotherapy and complete response rate for advanced gastric cancer increases.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

Psoriatic arthritis is a chronic systemic autoimmune disease, characterized by psoriasis skin lesions and inflammation of the spine and joint. It has complicated clinical manifestations and individual variations. Nearly half of the patients will have joints erosion in two years, which is crippling. The severity of the skin and joint disease frequently do not correlate with each other. Currently, the understanding of the disease is insufficient in China with the lack of standardized diagnosis and treatment. Therefore, researchers from the Chinese Rheumatology Association formulated this specification based on the diagnosis and management experience together with guidelines at home and abroad. The specification summarizes the present situation of domestic diagnosis and treatment, aiming to standardize the diagnosis process and treatment protocols of psoriatic arthritis. Furthermore, it can reduce misdiagnosis and missed diagnosis, as well as improve the prognosis.

Objective:To evaluate the efficacy and safety of programmed death 1 (PD-1), programmed death ligand 1 (PD-L1) immune checkpoint inhibitor (ICI) monotherapy for brain metastasis in advanced non-small cell lung cancer (NSCLC), and to explore the timing of immunomonotherapy and the application of hormone on the efficacy of ICI.Methods:By searching literature in CNKI, Wanfang, VIP, PubMed, CBM, Embase, Cochrane Library and Web of Science databases, the advanced NSCLC patients with brain metastasis who received ICI treatment were identified, including patients with symptomatic brain metastasis who had received hormone therapy or brain surgery or radiotherapy. Meta-analysis was performed on the collected data to evaluate the systemic objective response rate (sORR) and intracerebral tumor objective response rate (iORR), the iORR of whether ICI monotherapy was first-line therapy, and the iORR of whether hormone was used were evaluated, and the incidence of adverse reactions was evaluated.Results:Fifteen studies were finally included, with a total of 4 033 patients, including 917 patients with brain metastasis. The iORR of immunomonotherapy was 26% (95% CI 19%-34%) and the sORR was 28% (95% CI 18%-40%). The iORR of first-line immunomonotherapy was 49% (95% CI 39%-58%). The iORR of symptomatic patients with hormone therapy and asymptomatic patients without hormone therapy was 26% (95% CI 20%-33%) and 19% (95% CI 16%-22%), respectively. The overall incidence of grade 3-4 adverse reactions was 14% (95% CI 11%-17%). Conclusions:The efficacy of ICI monotherapy in the first-line treatment of PD-L1-positive NSCLC patients with brain metastasis is better than that in the subsequent line therapy, and the application of hormone does not affect the efficacy of ICI. ICI monotherapy in the treatment of advanced NSCLC patients with brain metastasis is safe.

Objective:To investigate the short- and long-term outcomes of fetuses with selective fetal growth restriction (sFGR).Methods:A retrospective study was conducted on monochorionic diamniotic (MCDA) twins with sFGR admitted to the Neonatal Intensive Care Unit of Peking University Third Hospital from September 2017 to December 2019. MCDA neonates delivered during the same period without significant complications were selected as the control group. MCDA twins with sFGR were divided into type Ⅰ, Ⅱ, and Ⅲ groups and then further divided into the larger and the smaller fetus subgroups according to the birth weight. These children were followed up by telephone at 2-3 years old. Height-for-age and weight-for-age Z-scores were calculated. Ages and Stages Questionnaire-Third Edition (ASQ-3) was used to determine comprehensive development. Independent sample t-test, one-way analysis of variance, non-parameter test, and Chi-square test (or rank-sum test) were used for statistical analysis. Results:(1) A total of 116 pregnant women with sFGR (232 neonates) were enrolled in this study. There were 43, 40, and 33 mothers and 86, 80, and 66 newborns in type Ⅰ, Ⅱ, and Ⅲ groups, respectively. The control group included 31 pregnant women and 62 neonates. The gestational age at onset of sFGR was younger in the type Ⅱ and Ⅲ groups than in type Ⅰ group [(23.8±4.8) and (24.1±3.1) vs (27.0±6.1) weeks, F=5.19, P<0.05; all P<0.017 during pairwise comparisons]. (2) The incidence of sepsis and treatment abandonment/death in neonates in type Ⅱ and Ⅲ groups were higher than those in type Ⅰ and control groups [neonatal sepsis: 11.3% (9/80) and 6.1% (4/66) vs 2.3% (2/86) and 0.0% (0/62), χ2=6.30, P=0.001; death or treatment abandonment rate:13.8% (11/80) and 10.6% (7/66) vs 3.5% (3/86) and 0.0% (0/62), χ2=4.68, P=0.003; all P<0.017 during pairwise comparisons]. In cases with type Ⅱ or type Ⅲ sFGR, the risk of digestive system diseases was significantly higher in the smaller fetus group than in the larger fetus group [type Ⅱ: 46.2% (37/80) vs 38.7% (31/80), χ2=16.72; type Ⅲ: 47.0% (31/66) vs 34.8% (23/66), χ2=39.69; both P<0.001], while the rate of respiratory system diseases was lower in the smaller fetus group [type Ⅱ: 35.0% (28/80) vs 45.0% (36/80), χ2=36.85; type Ⅲ: 37.9% (25/66) vs 45.4% (30/66), χ2=12.55; both P<0.001]. The incidence of neonatal sepsis in smaller fetuses was higher than that in larger ones in type Ⅱ sFGR [7.5% (6/80) vs 3.7% (3/80), χ2=4.68, P=0.034]. The incidence of neurological complications in larger fetuses was higher than that in smaller ones in type Ⅲ sFGR [15.1% (10/66) vs 4.5% (3/66), χ2=5.72, P<0.001]. (3) In type Ⅱ group, seven neonates died (one case of cerebral hemorrhage, two cases of gastrointestinal perforation, two cases of septic shock, and two cases of necrotizing enterocolitis), and four cases withdrew the treatment. In type Ⅲ group, four neonates died (two cases of necrotizing enterocolitis, one case of gastrointestinal perforation, and one case of cerebral hemorrhage), and three cases withdrew from the treatment. (4) Totally, 71 children in type Ⅰ, 61 in type Ⅱ, and 58 in type Ⅲ group were followed up at the age of 2-3. Children with type Ⅱ or type Ⅲ sFGR lagged behind those in type Ⅰ group and control group in physical growth [ M ( P25- P75), Z-scores:－0.46 (－0.87-0.42),－0.35 (－0.62-0.71), 0.05 (－0.61-0.51), and 0.14 (－0.57-0.75); H=6.20, P=0.001]. In type Ⅱ and Ⅲ groups, the smaller fetuses lagged the larger fetuses in physical growth at 2-3 years of age. ASQ-3 scores in communication, gross motor, fine motor, problem-solving and personal-social areas were all lower in type Ⅱ and Ⅲ groups than in type Ⅰ and control groups. ASQ-3 scores in the five dimensions of the smaller fetuses in the type Ⅱ group were lower than those of the larger fetuses. In the type Ⅲ group, the smaller fetuses had lower ASQ-3 scores in communication and gross motor than the larger ones [communication ability: (42.6±18.8) vs (56.4±9.4) scores, t=19.63, P<0.001; gross motor: (45.5±19.7) vs (54.5±9.7) scores, t=12.64, P=0.003]. Conclusion:The neonatal morbidity is significantly increased in type Ⅱ and Ⅲ sFGR, and babies lagged others in height, weight, and ASQ-3 score at 2-3, which is worthy of early attention.

OBJECTIVE：To study the intervention effects of Huan gqi injecti on on leucopenia model mice. METHODS ： Kunming mice were randomly divided into normal group ，model group and drug group ，with 8 mice in each group. Model group and drug group were given intraperitoneal injection of cyclophosphamide to induce leukopenia model. Normal group was given intraperitoneal injection of equal volume of sterile water. After modeling successfully ，normal group and model group were given intraperitoneal injection of equal volume of sterile water ；drug group was given intraperitoneal injection of Huangqi injection 0.04 mL/10 g，once a day ，for consecutive 7 d. Based on the detection of blood routine indexes （leukocyte，lymphocyte，neutrophil， monocyte count ）of mice in each group ，the metabolites in serum were analyzed by LC-MS. Principal component analysis （PCA）， partial least squares discriminant analysis （PLS-DA），orthogonal partial least squares-discriminant analysis （OPLS-DA），HMDB， METLIN， KEGG and other databases as well as related literatures were used to identify the differential metabolites. The metabolic pathways of differential metabolites were analyzed with MetPA online tools ，and the correlation of blood routine indexes and differential metabolites were analyzed on the basis of Pearson correlation coefficient. RESULTS： Compared with normal group ， blood rountine indexes of model group were decreased significantly （P＜ 0.01）. Compared with model group ，above blood r ountine indexes of drug group were all increased siginificantly （P＜0.01）. LC-MS chromatogram of serum samples in normal group and model group were significantly different ，and LC-MS metabonomics data of serum samples in drug group were similar to those of normal group. Multivariate statistical analysis and correlated database analysis revealed that compared with normal group ，serum contents of 17 metabolites as L-isoleucine，eicosapentaenoic acid were increased significantly in model group ，while the contents of 4 metabolites as spermidine were decreased significantly （P＜0.05 or P＜0.01）. Compared with model group ，Huangqi injection could reverse the serum contents of 9 metabolites in mice ，such as citric acid ，L-proline，acetylcarnitine，L-isoleucine， L-phenylalanine，sphingosine-1-phosphate，lysophosphatidylinositol，eicosapentaenoic acid and linoleic acid （P＜0.05 or P＜ 0.01），which were associated with linoleic acid metabolism ，biosynthesis of phenylalanine ，tyrosine and tryptophan ，and phenylalanine metabolism （metabolism pathway influential values were all higher than 0.1）. Correlation analysis showed that there was a significant correlation between blood routine indexes and the contents of D-sphingosine，linoleic acid and citric acid in model group（the absolute values of r were generally greater than 0.5）. CONCLUSIONS ：Huangqi injection can increase the counts of leukocytes，lymphocytes，neutrophils and monocytes in leucopenia model mice. The increase of leukocytes may be related to linoleic acid metabolism ，biosynthesis of phenylalanine ，tyrosine and tryptophan ，and phenylalanine metabolism.
