Magnetic resonance imaging (MRI), as a non-invasive neuroimaging technique, has been widely employed to investigate changes in functional brain regions. In recent years, the application of MRI in the study of lifelong premature ejaculation (LPE) has progressively uncovered the pathological mechanisms underlying abnormalities in LPE-associated brain regions. These mechanisms involve brain areas associated with higher-order cognitive and decision-making regulation, sensory and perceptual processing, as well as emotional regulation and reward systems. The application and findings of MRI in the study of LPE mechanisms will be introduced in this review, with the goal of deepening our understanding of the neuroimaging-based mechanisms of LPE.

Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

Photodynamic therapy is an emerging cancer therapy with clinical prospects, which plays a specific role in the tumor site and causes less harm to the human body. However, the toxicity of small molecules of hydrophobic photosensitizer, the tumor hypoxia microenvironment, and the biodegradability of nano-carrier systems affect its antitumor efficacy and metabolic clearance in vivo. In this paper, hexachloroplatinic acid was used as a novel oxidizing agent to initiate oxidative polymerization of pyrrole/amino pyrrole to achieve the amino functionalization; further reduced platinum acid anion in the nanostructures into platinum nanoclusters by sodium borohydride as a reducing agent to fabricate platinum nanocluster-doped polypyrrole nanoparticles (PtPPy); and finally, this functional nanoparticles delivering meso-tetra (4-carboxyphenyl) porphine (TCPP) were obtained by amide-bonded coupling of photosensitizers TCPP drug (PtPPy@T). The nanomedicine had a spherical structure, uniform morphology, a particle size of 91.93 ± 13.45 nm, and a zeta potential of -18.39 ± 1.4 mV. Experiments demonstrated that PtPPy@T could react with hydrogen peroxide overexpressed in the tumor to generate a large amount of oxygen, which could relieve the tumor hypoxia microenvironment, and at the same time, provided a sufficient substrate for the subsequent PDT; using 658 nm laser irradiation, the photodynamic effect of PtPPy@T was activated, which catalyzed the conversion of oxygen to singlet oxygen, thus triggering oxidative damage and inducing apoptosis in tumor cells; experimental studies showed that the PtPPy@T nanomedicine had a better tumor inhibitory effect in vivo and in vitro. All animal experiments were approved by the Institutional Animal Care and Use Committee of the Institute of Radiological Medicine, Chinese Academy of Medical Sciences and Peking Union Medical College (IRM/2-IACUC-2312-006).

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Photothermal therapy is a new type of tumor therapy that uses near-infrared laser to specifically activate the photothermal agent accumulated in the lesion site, so as to achieve thermal ablation of cancer cells. However, the long metabolic cycle and difficult clearance of photothermal agent materials in vivo are also one of the major obstacles hindering their clinical transformation. In this work, we used hemoglobin as a novel stabilizer, hexachloroplatinic acid as a novel oxidant, and pyrrole as a monomer to prepare hemoglobin-stabilized platinum-based polypyrrole nanoparticles (Hb@PtP) by a one-step oxidative polymerization method and investigated in detail to study their physicochemical properties, such as morphology and structure. After polyethylene glycol modification, the particle size of obtained Hb@PtPP was 99.08 ± 8.3 nm and the zeta potential was -18.7 ± 1.2 mV. Transmission electron microscopy showed that the Hb@PtPP nanoparticles exhibited irregular spherical shape and uniform dispersion in the system. Under the irradiation of 808 nm laser with different power densities, Hb@PtPP showed power density-dependent temperature-raising behavior, and CCK-8 and dead-live staining experiments confirmed that they could effectively exert the photothermal effect to kill tumor cells. Small living animal imaging results demonstrated that Hb@PtPP had good tumor targeting and retention ability, and achieved tumor growth inhibition and ablation in vivo under laser excitation. All animal experiments involved in the study were performed in accordance with the program approved by the Animal Care and Use Committee of the Chinese Academy of Medical Sciences, Beijing Union Medical College, Institute of Radiation Medicine [IRM/2-IACUC-2312-005].

Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

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.

Aim To investigate the effects of Ginkgo biloba extract(GBE)on vascular endothelial dysfunc-tion induced by chronic intermittent hypoxia(CIH)in rats and its related mechanisms.Methods The CIH rat model was established,and 50 and 100 mg·kg-1 GBE was administered by intragastric administration.The systolic blood pressure(SBP)of the tail artery was detected in each group.HE staining was used to detect the morphology of aorta tissue.DAF-FM DA staining and nitric reductase assay were used to detect NO levels.ELISA was used to detect serum ET-1,TNF-α and IL-6 levels.DHE staining was used to de-tect reactive oxygen species(ROS)levels of aortic tis-sue.Kits were used to detect the serum levels of MDA,SOD and GSH-Px.Western blot was used to detect the levels of VCAM-1,ICAM-1,nucleus Nrf2,HO-1 and NQO1 of aortic tissue.Results GBE sig-nificantly decreased the levels of SBP,ET-1,ROS,MDA,VCAM-1,ICAM-1,TNF-α and IL-6,and sig-nificantly increased the levels of NO,SOD,GSH-Px,nuclear Nrf2,HO-1 and NQO1 in CIH rats.GBE sig-nificantly improved the histomorphology of aorta in CIH rats.Conclusions GBE can improve vascular endo-thelial dysfunction and reduce blood pressure in CIH model rats.The mechanism may be related to the acti-vation of Nrf2/ARE pathway and the inhibition of oxi-dative stress and inflammation by GBE.

Professor HAN Wei 's clinical experience of acupuncture and moxibustion with Tongyang Xingshen (promoting yang and regaining consciousness) for adolescent depressive disorder is introduced. It is believed that the internal causes of adolescent depressive disorder are mostly emotional and physical factors, while the external causes are mainly social factors, and yang-qi stagnation and emotional disorder are the key pathogenesis. The key of acupuncture and moxibustion with Tongyang Xingshen is warming and regulating the governor vessel. The governor vessel acupoints at head, neck and back are selected. At head, Baihui (GV 20) and Yintang (GV 24⁺) are selected; at neck, Fengfu (GV 16) and Dazhui (GV 14) are selected; at back, Taodao (GV 13), Shenzhu (GV 12), Shendao (GV 11), Zhiyang (GV 9) and Jinsuo (GV 8) are selected. The combination of disease differentiation and syndrome differentiation should be highly valued, and the moxibustion with Tongyang and acupuncture with Xingshen should be used simultaneously, and the strong stimulation is suggested.

OBJECTIVE: To observe the effect of Tongdu Tiaoshen (promoting the circulation of the governor vessel and regulating the spirit) electroacupuncture (EA) pretreatment on pyroptosis mediated by peroxisome proliferators-activated receptor γ (PPARγ) of the cerebral cortex in rats with cerebral ischemia reperfusion injury (CIRI) and explore the potential mechanism of EA for the prevention and treatment of CIRI. METHODS: A total of 110 clean-grade male SD rats were randomly divided into a sham-operation group, a model group, an EA group, an EA + inhibitor group and an agonist group, 22 rats in each group. In the EA group, before modeling, EA was applied to "Baihui" (GV 20), "Fengfu" (GV 16) and "Dazhui" (GV 14), with disperse-dense wave, 2 Hz/5 Hz in frequency, 1 to 2 mA in intensity, lasting 20 min; once a day, consecutively for 7 days. On the base of the intervention as the EA group, on the day 7, the intraperitoneal injection with the PPARγ inhibitor, GW9662 (10 mg/kg) was delivered in the EA + inhibitor group. In the agonist group, on the day 7, the PPARγ agonist, pioglitazone hydrochloride (10 mg/kg) was injected intraperitoneally. At the end of intervention, except the sham-operation group, the modified thread embolization method was adopted to establish the right CIRI model in the rats of the other groups. Using the score of the modified neurological severity score (mNSS), the neurological defect condition of rats was evaluated. TTC staining was adopted to detect the relative cerebral infarction volume of rat, TUNEL staining was used to detect apoptosis of cerebral cortical nerve cells and the transmission electron microscope was used to observe pyroptosis of cerebral cortical neural cells. The positive expression of PPARγ and nucleotide-binding to oligomerization domain-like receptor protein 3 (NLRP3) in the cerebral cortex was detected with the immunofluorescence staining. The protein expression of PPARγ, NLRP3, cysteinyl aspartate specific protease-1 (caspase-1), gasdermin D (GSDMD) and GSDMD-N terminal (GSDMD-N) in the cerebral cortex was detected with Western blot. Using the quantitative real-time fluorescence-PCR, the mRNA expression of PPARγ, NLRP3, caspase-1 and GSDMD of the cerebral cortex was detected. The contents of interleukin (IL)-1β and IL-18 in the cerebral cortex of rats were determined by ELISA. RESULTS: Compared with the sham-operation group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were increased (P<0.01), pyroptosis was severe, the protein and mRNA expression levels of PPARγ, NLRP3, caspase-1 and GSDMD were elevated (P<0.01); and the protein expression of GSDMD-N and contents of IL-1β and IL-18 were increased (P<0.01) in the model group. When compared with the model group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were decreased (P<0.01), pyroptosis was alleviated, the protein and mRNA expression levels of PPARγ were increased (P<0.01), the protein and mRNA expression levels of NLRP3, caspase-1 and GSDMD were decreased (P<0.01), the protein expression of GSDMD-N was reduced (P<0.01); and the contents of IL-1β and IL-18 were lower (P<0.01) in the EA group and the agonist group; while, in the EA + inhibitor group, the protein expression of PPARγ was increased (P<0.01), the protein and mRNA expression levels of NLRP3 and GSDMD were decreased (P<0.01, P<0.05), the mRNA expression of caspase-1 was reduced (P<0.01); and the contents of IL-1β and IL-18 were lower (P<0.01). When compared with the EA + inhibitor group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were decreased (P<0.05, P<0.01), pyroptosis was alleviated, the protein and mRNA expression levels of PPARγ were increased (P<0.01), the protein and mRNA expression levels of NLRP3, caspase-1 and GSDMD were decreased (P<0.01), the protein expression of GSDMD-N was reduced (P<0.01); and the contents of IL-1β and IL-18 were declined (P<0.01) in the EA group. Compared with the agonist group, in the EA group, the relative cerebral infarction volume and the TUNEL positive cells rate were increased (P<0.05, P<0.01), the mRNA expression of PPARγ was decreased (P<0.01) and the protein expression of GSDMD-N was elevated (P<0.05); and the contents of IL-1β and IL-18 were higher (P<0.01). CONCLUSION Tongdu Tiaoshen EA pretreatment can attenuate the neurological impairment in the rats with CIRI, and the underlying mechanism is related to the up-regulation of PPARγ inducing the inhibition of NLRP3 in the cerebral cortex of rats so that pyroptosis is affected.
