The purpose of this paper is to explore the decoction and dosing methods of rhubarb root and rhizome in classical prescriptions and to provide a reference basis for the clinical use of rhubarb root and rhizome. By collating the relevant classical prescriptions of rhubarb root and rhizome in Shanghan Lun and Jingui Yaolüe, the relationship between its decoction and dosing methods and the syndrome was analyzed. The decoction of rhubarb root and rhizome in classical prescriptions can be divided into three categories: simultaneous decoction, decoction later, and other methods (impregnation in Mafei decoction, decoction with water from the well spring first taken in the morning, and pills). If it enters the blood level or wants to slow down, rhubarb root and rhizome should be decocted at the same time with other drugs. If it enters the qi level and wants to speed up, rhubarb root and rhizome should be decocted later. If it wants to upwardly move, rhubarb root and rhizome should be immersed in Mafei decoction. If it wants to suppress liver yang, rhubarb root and rhizome should be decocted with water from the well spring first taken in the morning. If the disease is prolonged, rhubarb root and rhizome should be taken in pill form. The dosing methods of rhubarb root and rhizome can be divided into five categories: draught, twice, three times, before meals, and unspecified. For acute and serious illnesses with excess of pathogenic qi and adequate vital qi, we choose draught. For gastrointestinal diseases, we choose to take the medicine twice. For achieving a moderate and long-lasting effect, we choose to take the medicine three times. If the disease is located in the lower part of the heart and abdomen, we choose to take it before meals. The use of rhubarb root and rhizome in clinical practice requires the selection of the appropriate decoction and dosing methods according to the location of the disease, the severity of the disease, the patient′s constitution, and the condition after taking the medicine.

" Lijie and yellowish sweating" originates from the chapter on stroke and arthralgia diseases in Synopsis of Golden Chamber. Later generations typically interpret it as yellow fluid oozing from painful joints, a characteristic manifestation of arthralgia. In Western medicine, Lijie corresponds to diseases such as gouty arthritis, with its primary clinical manifestations being redness, swelling, heat, and painful joints, most often without yellow fluid discharge. Therefore, the interpretation of " Lijie and yellowish sweating" contradicts the clinical manifestations often observed in this disease. Thus, this article reinterprets the meaning of " Lijie and yellowish sweating" from the pathogenesis of " sweat exposure to water, as if water harms the heart" , combined with the viewpoints of other medical practitioners. Determining the meaning of " yellowish sweating" is crucial for understanding the pathogenesis of arthralgia and clarifying the relationship between arthralgia and yellowish sweating. ZHANG Zhongjing mentioned arthralgia and " yellowish sweating" together, not to differentiate between the two diseases but to emphasize the common pathogenesis of the two, namely, the cold and dampness injuring the heart, blood, and vessels. This paper proposes a new explanation of " Lijie and yellowish sweating" , which suggests that " yellowish sweating" is not confined to the joints but can be found all over the body. The pathogenesis of " Lijie and yellowish sweating" lies in the insufficiency of the liver and kidney and exogenous water dampness, leading to disharmony between nutrient qi and defensive qi and between yin and yang. Primary treatment should harmonize yingfen and weifen, as well as tonify and replenish the liver and kidney. The clinical selection of medicines can be considered Guizhi Decotion, a type of formula. The pathogenesis of " Lijie and yellowish sweating" is complex, and clinical treatment should be comprehensively considered to achieve the best therapeutic effect.

Objective:To explore the safety and reliability of retrosigmoid approach BONEBRIDGE implantation in patients with auricle reconstruction using skin expansion flap.Methods:A retrospective analysis was conducted on 43 congenital aural atresia cases (43 ears) who underwent BONEBRIDGE implantation from September 2019 to January 2023 in Beijing Tongren Hospital. 30 males and 13 females were included in this work. The implantation age was 9-36 years old (median age=10 y/o). All cases underwent auricle reconstruction surgery using the posterior ear flap expansion method, with 36 cases using the single expanded postauricular flap method and 7 cases using two-flap method. BONEBRIDGE implant surgery was performed during the third stage of auricle reconstruction or after all stages. The hearing improvements were evaluated by comparing the changes in pure tone hearing threshold and speech recognition rate of patients before and after BONEBRIDGE implantation. Routine follow-up was conducted to observe the hearing results and complications. SPSS 14.0 software was applied for data statistical analysis.Results:All 43 patients healed well and had no surgical complications when discharge. The average bone conduction hearing threshold after surgery was (8.2±6.6) dBHL, and there was no statistically significant difference compared to the preoperative [(8.1±5.7) dBHL] ( P=0.95). After surgery, the threshold of hearing assistance with power on was significantly lower than that without hearing assistance [(32.8±4.6) dBHL vs (60.5±5.5) dBHL], and the difference was statistically significant ( P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased to 72%, 84%, and 98% respectively. The differences were statistically significant ( P<0.001). The speech recognition rate of monosyllabic words, disyllabic words, and short sentences in noise environment was significantly increased by 70%, 80%, and 92% respectively ( P<0.001). After a follow-up of 4 to 47 months (median=24 months), the hearing results were stable and the aesthetic outcomes were satisfying. One patient had delayed hematoma around coil of the implant. After aspiration and compressed dressing for one week, hematoma was not recurrent. Conclusion:For patients after auricle reconstruction using expanded postauricular flap, the preference of retrosigmoid approach is a good choice in terms of safety and reliability of operation, as well as aesthetic appearance.

Inflammation plays an important role in the occurrence, development and outcome of ischemic stroke. As one of the most sensitive indicators of inflammation, interleukin (IL)-6 is associated with the risk of ischemic stroke and plays a dual role in ischemic stroke. In-depth study on the changes and role of IL-6 level in patients with ischemic stroke may help to develop new methods to predict the outcome of ischemic stroke and promote the prevention and treatment of ischemic stroke.

As an extracorporeal life support technology, veno-venous extracorporeal membrane oxygenation (VV-ECMO) has been demonstrated its role in the treatment of patients with severe respiratory failure. Its main advantages include the ability to maintain adequate oxygenation and remove excess CO2, increase oxygen delivery, improve tissue perfusion and metabolism, and implement lung protection strategies. Clinicians should accurately assess and identify the patient's condition, timely and accurately carry out VV-ECMO operation and management. This article will review the patient selection, cannulation strategy, anticoagulation, clinical management and weaning involved in the application of VV-ECMO.

Objective To investigate the imaging features of the cerebral complications of infective endocarditis (IE)and the evolution process of infective cerebral infarction.Methods The clinical and imaging data from 5 patients diagnosed as IE with neurological complications were retrospectively and comprehensively reviewed,so that the imaging features of cerebral complications and infective cerebral infarctions were summarized.Results Among the 5 cases,3 showed multiple acute infarctions,including 2 massive ones.All the 5 cases showed multiple hemorrhagic lesions at different stages.The infarction and hemorrhage were mostly located at the corticalGmedullary junction.1 case of subarachnoid hemorrhage and 1 case of meningitis were also observed.Two massive infarctions mentioned above showed irregular patchy shape,which evolved into cerebral abscesses after 1 2 and 1 5 days of neurological symptoms showing up,then abscesses started shrinking after 33 and 3 1 days,respectively.Conclusion MRI can accurately reflect the features of cerebral complications of IE and the evolution process of infective cerebral infarctions,which provides evidences for physicians to make correct diagnoses and the treatment plans.

Objective: To discuss the safety and efficacy of simultaneous procedures of vibrant soundbridge implantation and auricular reconstruction with congenital external and middle ear malformation. Methods: This is a retrospective study, including 6 patients, 5 boys and 1 girl, aged 7-12 years. All patients received simultaneous operations of vibrant soundbridge implantation and auricular reconstruction. The mean preoperative air conduction threshold was 64.8 dB HL at 0.5, 1, 2, and 4 kHz. The VSB was placed in the third stage of auricle reconstruction, if the soft tissue expansion was performed; otherwise, the VSB was implanted in the second stage. The satisfaction with reconstructed auricle, surgical complications, hearing improvement and speech discrimination scores were evaluated 6 months after surgery. Results: All patients and their families reported satisfaction with their reconstructed auricle. There was no complications, including cartilage framework exposion, infection, hematoma, skin flap necrosis, facial paralysis, tinnitus, vertigo or others. Post-operatively, mean VSB-aided hearing threshold was 36.7 dB HL, which was reduced by 28.1 dB HL. The mean speech discrimination scores measured in a sound field with a presentation level of 65 dB SPL and 80 dB SPL were improved. Conclusions The simultaneous operations of auricle reconstruction and Vibrant Soundbridge implantation is an alternative method for patients with congenital microtia and atresia.

Objective To analyze the clinical,radiological features and risk factors of diplopia in patients with acute lacunar infarction (ALI).Methods Retrospectively retrieved patients of ALI (lesion diameter was less than 1.5 cm in DWI sequence)diagnosed by MR and clinical.We further summarized 13 ALI patients with diplopia and randomly selected 13 ALI patients without diplopia as the control group. SPSS22.0 statistical software was used for statistical analysis.The general clinical data such as sex and age was compared by Ch-i square test and t-test.The risk factors were primarily analyzed by one-way ANOVA and then the risk factors with statistical significance were brought into the logistic regression model for multivariate analysis.Results The incidence of diplopia in ALI patients was about 2.7%(13/489). The infarct sites were all located in the brain stem of the oculomotor-related brain nucleus and the dorsolateral medulla oblongata.Hypertension and hematocrit were negatively correlated with diplopia after infarction (P＜0.05 ).Conclusion The incidence of diplopia is low in ALI patients.The medial longitudinal tract of the dorsolateral medulla is an important area causing diplopia.Hypertension and hematocrit are non-risk factors for diplopia after ALI.

Objective To study the different ischemic characteristics of cerebral gray matter and deep white matter in patients with chronic cerebral artery severe stenosis or occlusion. Methods A retrospective study was conducted on 30 patients with chronic unilateral cerebral artery severe stenosis or occlusion from April 2014 to April 2018 in our hospital. Cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), time of peak time (TTP) and time to delay(TTD) of cerebral cortex gray matter and deep white matter in the blood supply area of the responsible artery (the affected side) and the contralateral hemisphere (the healthy side) were measured. Statistical analysis of the perfusion parameters of cerebral cortex gray matter and deep white matter in the affected side and contralateral side were performed using SPSS13.0 software package. T test was used for variance homogeneity, and t′test was used for variance discrepancy, and P<0.05 was statistically significant. Results The average values of CBF and CBV of the ipsilateral and contralateral cerebral cortex were increased than those of ipsilateral and contralateral cerebral deep white matter respectively(P<0.01). MTT, TTP and TTD of the ipsilateral and contralateral cerebral cortex were decreased than that of ipsilateral and contralateral cerebral deep white matter (P<0.01); CBF of ipsilateral cerebral cortex and CBV of ipsilateral cerebral deep white matter were not different from those of the contralateral cerebral cortex and deep white matter respectively, but CBF of ipsilateral cerebral deep white matter is decreased than that of the contralateral deep white matter (P<0.01). CBV of ipsilateral cerebral cortex is increased than that of the contralateral cerebral cortex (P<0.01). MTT, TTP and TTD of ipsilateral cerebral cortex and deep white matter were increased than those of contralateral cerebral cortex and deep white matter respectively(P<0.01). Conclusion Deep cerebral white matter perfusion decreased more significantly than cortical gray matter in the supply region of chronic cerebral artery severe stenosis or occlusion. CT perfusion imaging can quantify the degree of chronic cerebral ischemia and can provide quantitative diagnostic information for clinical treatment and efficacy evaluation.
