ObjectiveTo assess the therapeutic effectiveness and safety of the traditional Chinese medicine compound Shenlong decoction in addressing the symptoms of pulmonary deficiency and stasis in patients with idiopathic pulmonary fibrosis （IPF）. MethodsSixty eligible patients with lung deficiency and collateral stasis syndrome of IPF were randomly assigned to the observation （30 patients） and control groups （30 patients）. All patients underwent standard Western medical therapy. Additionally，the observation group received Shenlong decoction granules，while the control group received a placebo. Both treatments were packaged in four doses of 10.5 g each，taken twice daily for three months. The indexes of the patients during the treatment cycle were observed，and the main indexes include traditional Chinese medicine （TCM） syndrome scores and 6 min walk test （6MWT）. The secondary indexes include pulmonary function test ［actual value/expected value of total lung volume （TLC%），actual value/expected value of vital capacity（FVC%），actual/predicted diffusing capacity of the lung for carbon monoxide（DLCO%），actual/predicted forced expiratory volume in one second （FEV₁%），and FEV₁/ forced vital capacity （FVC）］，blood gas analysis ［arterial blood diathesis partial pressure of oxygen （PaO₂），partial pressure of carbon dioxide （PaCO₂），and arterial oxygen saturation （SaO₂）］，serum inflammatory factors ［transforming growth factor-β₁ （TGF-β₁），interleukin-4 （IL-4），interleukin-13 （IL-13），interleukin-12 （IL-12），and gamma-interferon （IFN-γ）］，and quality of survival evaluation ［St George's Respiratory Questionnaire （SGRQ） score］. The patients' clinical manifestations were determined at the end of the treatment， and the occurrence of adverse events was recorded. ResultsA total of 53 patients completed the study，comprising 27 in the control group and 26 in the observation group. Upon completion of the treatment period，the control group achieved a total effective rate of 33.33% （9/27），whereas the observation group demonstrated a total effective rate of 53.85% （14/26），which was statistically superior to the control group （χ²=4.034，P<0.05）. After the treatment，the TCM syndrome scores，6MWT，DLCO%，FEV₁%，PaO₂，PaCO₂，TGF-β₁，IL-4，IL-13，IL-12，and IFN-γ in the two groups were all significantly improved （P<0.01）. Compared with those in the control group after treatment at the same period，the TCM syndrome scores，6MWT，PaO₂，and PaCO₂ were significantly improved in the observation group after 60 days and 90 days of medication （P<0.01）. Three months after the end of medication，the SGRQ score in the observation group showed significant improvement when compared to that in the control group （P<0.05），and no severe adverse events were reported during the follow-up period. ConclusionCompound Shenlong decoction can alleviate clinical symptoms such as shortness of breath and wheezing in patients with lung deficiency and collateral stasis syndrome of IPF，enhance exercise tolerance，improve the quality of life，and have certain potential advantages in improving pulmonary function.

Objective To explore the effect of the blood flow restriction(BFR)at 40%arterial oc-clusive pressure(AOP)on ergometer cycling maximal lactate steady state(MLSS).Methods A total of 11 male college students majoring in sports science(age 23±2 yrs,height 176±5 cm,weight 74.6±5.5 kg,body fat 14.5%±4.7%)were selected.The test in this study was divided into 4 parts:① an incremental ramp test to determine the maximal aerobic power(Pmax);② the MLSS test to determine the blood lactate concentration of MLSS(MLSSc),the work load of MLSS(MLSSw),and the percentage of MLSSw relative to Pmax(%MLSSw);③ the 30 min constant load BFR test(MLSS-BFR)of MLSSw based on the test ② to determine the heart rate,blood lactate and subjec-tive fatigue of MLSSw at the BFR;④ MLSS test at BFR(BFR-MLSS)to determine MLSSc and MLSSw.The BFR was performed using an adjustable pressure compression cuff applied externally to the nearest point to the thigh,at a pressure of 40%AOP.Heart rate was monitored throughout the test.When measuring the constant load in test ②③④,restrictive pressure was released for 30 s ev-ery 5 min.During the release,a blood sample was collected from the earlobe for analysis of blood lac-tate.After the constant load test,the perceived exertion was collected immediately.Results MLSSw(152.5±28.8 vs 161.3±28.1 W,P<0.05,ES=0.84)and%MLSSw(53.4%±5.7%vs 56.7%±5.5%,P<0.05,ES=0.82)of BFR-MLSS test were significantly lower than those of MLSS test.However,no significant differences were found between the BFR-MLSS and MLSS test in MLSSc(5.61±1.18 vs 5.61±0.81 mmol/L,P>0.05,ES=0.01),heart rate(152.6±14.8 vs 150.7±10.7 bpm,P>0.05,ES=0.17)and RPE(14.8±3.3 vs 14.9±2.9,P>0.05,ES=0.06).Conclusion BFR exercise achieves MLSS at a lower external load(power output),and does not reduce the internal load of MLSS.Moreover,BFR increases the internal load for the same external load,but the division of the internal load interval seems to be the same during exercise with or without BFR.

Guided by the pathogenesis of"structure-activity imbalance of lung collaterals",this paper proposes that structure-activity imbalance of lung collaterals is the initial factor of idiopathic pulmonary fibrosis(IPF)and elucidates the pathogenesis of abnormal changes in biomechanical properties of IPF.It is postulated that the changes of biomechanical properties of lung tissue are closely related to the injury of lung qi collaterals,the abnormal mechanical stress are closely related to the injury of lung blood collaterals,and the biomechanical response of intrapulmonary resident cells is closely related to the structure-activity imbalance of lung collaterals,which ultimately leading to abnormal increase in lung tissue stiffness and progressive scarring formation in lung tissue.Integrating traditional pathogenesis concepts with microscopic pathological changes,and the in-depth exploration of the correlation between the structure-activity imbalance of lung collaterals and the biomechanical properties of IPF can provide direction for exploring IPF medical-engineering cross research,which are of great significance for enriching the syndrome and treatment system of lung collateral diseases.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective To evaluate the effectiveness of a 1470 nm semiconductor laser therapeutic instrument(referred to as a curestar therapeutic instrument)for prostatectomy in Beagle dogs.Methods Twenty-eight adult male Beagle dogs were randomly divided into three groups:sham(n=3),experimental(n=15),and control(n=10).The experimental group was further divided into three subgroups:120 W/50 W,150 W/50 W,and 160 W/50 W for vaporization cutting/coagulation hemostasis.The control group was divided into two subgroups:120 W/50 W and 150 W/50 W with five in each subgroup.Experimental and control groups underwent canine prostatectomy through the entrance of the bladder neck under electrocision.The operational suitability and effectiveness of the product during surgery were assessed.After the operation,the general condition of the dogs was observed,and blood biochemical and hematological indicators were measured before,immediately after,and at 3,7,and 28 days after the operation.At 1 h and 4 weeks after surgery,B-ultrasound and electric resection were performed under anesthesia to observe the conditions of the urethra and prostate,and prostatic tissue was subjected to HE staining for pathological observations.The thickness of the coagulation layer at 1 h after the operation and repair of the urothelial epithelium at 4 weeks were analyzed.Results During the operation,experimental and control groups had good operability and showed good vaporization cutting and coagulation hemostasis performance.After the operation,no significant effects were observed on the general condition,and blood biochemical and hematological indicators of the dogs.Ultrasound showed that the urethral expansion was visible immediately after the operation,and the echo of the urethral epithelium was slightly enhanced.At 4 weeks,the prostate tissue had a slightly low echo with uniformly distributed small point-like echoes inside,and the capsule had a linearly high echo,consistent with the sham group.The weight of the vaporized prostate tissue in experimental and control groups was 0.91～1.33 g with a resection rate of 17.11％～20.27％.As the power of vaporization cutting increased,the laser emission time gradually decreased,while the vaporization cutting speed and efficiency both increased.However,no significant difference was found between experimental and control groups(P＞0.05).Under the electrocision microscope,a burn-like change was observed in the surgical wounds of the prostate urethra in experimental and control groups at 1 h after surgery,and the boundary between the wound and normal urothelium was visible.At 4 weeks,the urothelium of the prostate had been repaired and flattened,and the boundary with the surrounding normal urothelium was blurred.Similarly,pathological observations showed that experimental and control groups had significant damage to the prostate urethral orifice at 1 h after surgery with a small amount of carbonization and coagulative necrosis on the surface of the wound,a small amount of inflammatory cell infiltration,and a coagulation layer thickness of approximately 0.4 mm.At 4 weeks,the prostate urethral morphology of the sham group was normal,whereas experimental and control groups showed new epithelial growth covering the wound with a uniform thickness and no coagulative necrosis tissue attached to the wound.A mild inflammatory reaction was still present in the surrounding area,fibroblast proliferation was obvious,and stromal and epithelial cell proliferation was visible in the surrounding prostate,some of which showed squamous metaplasia.The prostate capsule was intact and the morphology of the surrounding nerves and blood vessels was normal.Conclusions The curestar therapy instrument is effective for prostatectomy in Beagle dogs with good vaporization cutting and coagulation hemostasis performance.No significant difference was found in postoperative physiological indicators compared with the sham group.

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.
