Based on the theory of collateral disease， the treatment of late-stage sequela of cerebrovascular disease is considered to be primarily associated with deficiency and obstruction of cerebral collaterals and dysfunction of the spirit mechanism. Therefore， the fundamental therapeutic principle is to unblock and supplement the brain collaterals. Clinically， the late-stage sequelae of cerebrovascular disease are classified into four patterns， which are malnourishment， deficiency-heat， stasis obstruction， and phlegm clouding of brain collaterals. These are treated respectively with Tiansui Tongqiao Decoction （填髓通窍汤） to supplement essence and nourish the brain through moistening， unblocking and supplementing， Qingnao Touluo Decoction （清脑透络汤） to enrich yin， regulate spirit， and unblock collaterals through clearing and penetrating， Yiqi Tongluo Decoction （益气通络汤） to tonify qi and resolve stasis while softening tendons and unblocking collaterals， and Xinrun Touqiao Beverage （辛润透窍饮） to unblock and tonify yin and yang while unblocking the collaterals through acrid-moistening medicinals. Flexible modification of prescriptions according to individual symptoms was applied， resulting in favorable therapeutic outcomes.

This article summarizes the clinical experience in diagnosing and treating narcolepsy based on the wei qi theory. The key pathogenesis of narcolepsy is considered to be the disharmony of wei qi. In the initial stage， lung， spleen， and kidney deficiency leads to insufficient generation and propulsion of wei qi. In the progressive stage， phlegm-damp and qi stagnation obstruct sanjiao （三焦）， while the interstice of flesh is unrelaxed， and the skin pores are occluded， causing sluggish circulation of wei qi. In the attack stage， pathogens obstruct the upper jiao （焦）， whereas pectoral qi fails to diffuse， and wei qi becomes constrained and blocked in the yin aspect， which may transform into wind or heat and bind with phlegm and stasis， resulting in sudden excessive sleep， cataplexy， dream disturbance， hallucinations， and sleep paralysis. Accordingly， a three-stage differentiation and treatment strategy is proposed， including reinforcing the root and strengthening wei qi in the initial stage with Peiben Shiwei Decoction （培本实卫汤）， resolving phlegm and unblocking the pathways to smooth the flow of wei qi in the progressive stage with Tongjiao Dawei Decoction （通焦达卫汤）， and diffusing wei qi， awakening the spirit， and opening the upper jiao in the attack stage with Xuanwei Xingshen Decoction （宣卫醒神汤）. Clinically， treatment should distinguish deficiency from excess， the primary from the secondary， administer staged and dynamic treatments， and make good use of light， clear， ascending， dispersing， acrid， and aromatic medicinals to restore the movement of wei qi， thereby providing a reference for differentiation and treatment of narcolepsy in traditional Chinese medicine.

Sweet syndrome (acute febrile neutrophilic dermatosis) is a relatively rare inflammatory di-sease, which is characterized by the sudden appearance of tender erythematous skin lesions, often accompanied by pyrexia and elevated neutrophil count. The pathogenesis is not clear yet. Recently, multiple studies have found the association between Sweet syndrome and infections, autoimmune diseases, malignant tumors and the application of multiple drugs. According to different causes, Sweet syndrome can be divided into three types: classical (or idiopathic) Sweet syndrome, malignancy-associated Sweet syndrome and drug-induced Sweet syndrome. Classical Sweet syndrome usually presents in women between the age of 30 to 50 years and may be related to infection, inflammatory bowel disease, or pregnancy. The clinical symptoms typically respond promptly after corticosteroid therapy. The major diagnostic criteria of classical Sweet syndrome include sudden painful erythematous skin lesions, histopathologic evidence of a dense neutrophilic infiltrate without evidence of leukocytoclastic vasculitis; minor criteria include pyrexia over 38 ℃, association with hematologic or visceral malignancies, inflammatory diseases, pregnancy or preceded by infection, prompt response to systemic glucocorticoid or potassium iodide treatment, abnormal laboratory values (three of four: erythrocyte sedimentation rate >20 mm/h, positive C-reactive protein, >8.0×10⁹/L leukocytes, >70% neutrophils). The presence of both major criteria and two of the four minor criteria are required to diagnose classical Sweet syndrome. As for the malignancy-associated Sweet syndrome, skin lesions can be found precede, follow, or at the same time with the diagnosis of hematologic malignancy or a solid tumor. At present, ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) is commonly used as a positron emission tomography computed tomography (PET/CT) imaging agent for diagnosing and screening malignant tumors. Therefore, most of the case reports on the ¹⁸F-FDG PET/CT manifestations of Sweet syndrome are malignancy-associated. Even classical Sweet syndrome is often accompanied by inflammatory bowel disease, autoimmune diseases, etc. Therefore, for patients with suspected or confirmed Sweet syndrome, it is necessary to take ¹⁸F-FDG PET/CT examination to clarify the general condition, whether it is for patients with malignant signs such as elevated tumor markers values and weight loss, or for patients with classical Sweet syndrome to exclude underlying inflammatory diseases. ¹⁸F-FDG PET/CT is often able to detect the solid tumor early, and assess the degree of hematologic malignancy and inflammatory disease. This study reported a classical Sweet syndrome case associated with inflammatory bowel disease, which was confirmed with skin and intestinal histological examination. The clinical manifestations, laboratory values, ¹⁸F-FDG PET/CT manifestations of the patient related diseases were reported, which was to improve nuclear medicine physicians' understanding of Sweet syndrome. Early diagnosis and treatment can often achieve excellent clinical effect.

Alzheimer's disease (AD) is the major form of dementia in the elderly and is closely related to the toxic effects of microglia sustained activation. In AD, sustained microglial activation triggers impaired synaptic pruning, neuroinflammation, neurotoxicity, and cognitive deficits. Accumulating evidence has demonstrated that aberrant expression of deubiquitinating enzymes is associated with regulating microglia function. Here, we use RNA sequencing to identify a deubiquitinase YOD1 as a regulator of microglial function and AD pathology. Further study showed that YOD1 knockout significantly improved the migration, phagocytosis, and inflammatory response of microglia, thereby improving the cognitive impairment of AD model mice. Through LC-MS/MS analysis combined with Co-IP, we found that Myosin heavy chain 9 (MYH9), a key regulator maintaining microglia homeostasis, is an interacting protein of YOD1. Mechanistically, YOD1 binds to MYH9 and maintains its stability by removing the K48 ubiquitin chain from MYH9, thereby mediating the microglia polarization signaling pathway to mediate microglia homeostasis. Taken together, our study reveals a specific role of microglial YOD1 in mediating microglia homeostasis and AD pathology, which provides a potential strategy for targeting microglia to treat AD.

ObjectiveThis paper aims to analyze the clinical characteristics and medication rationality of liver injury related to Epimedii Folium preparation （EP） and explore the possible risk factors of liver injury， so as to provide a reference for the safe clinical application of Epimedii Folium （EF）. MethodA retrospective analysis was conducted on liver injury cases related to EP from 2012 to 2016. ResultThe number of reported liver injury cases and the proportion of severe cases related to the use of EP show an increasing trend， indicating the objective existence of liver injury caused by EP. There are more cases of liver injury related to EP in women than in men， with an onset age range of 15-91 years old and a median onset age of 60 years old （median onset ages for men and women are 59 and 60 years old， respectively）. The time span from taking EP alone to the occurrence of liver injury is 1-386 days， with a median of 38 days. The time span from taking both EP and Western medicine to the occurrence of liver injury is 1-794 days， with a median of 34 days. EF-related liver injury preparations are mostly composed of traditional Chinese medicines that promote immunity and tonify the liver and kidney， indicating that immune stress in the body may be the mechanism of liver injury caused by the use of EP alone or in combination. There is no increasing trend of toxicity with time or dose in the liver injury caused by EP. By further exploring its risk factors， it is found that patients have unreasonable medication methods such as excessive dosage， repeated use， and multi-drug combination， which may also be one of the important risk factors for EF-related liver injury. ConclusionEP has a certain risk of liver injury and should be emphasized in clinical diagnosis and treatment. Immune stress may be the mechanism of liver injury caused by EP， and in clinical use， it is necessary to be vigilant about the risk of liver injury caused by unreasonable use and combined use with Western medicine.

Despite growing prevalence and incidence, the management of gout remains suboptimal. The intermittent nature of the gout makes the long-term urate-lowering therapy (ULT) particularly important for gout management. However, patients are reluctant to take medication day after day to manage incurable occasional gout flares, and suffer from possible long-term toxicity. Therefore, a safe and easy-to-operate drug delivery system with simple preparation for the long-term management of gout is very necessary. Here, a chitosan-containing sustained-release microneedle system co-loaded with colchicine and uricase liposomes were fabricated to achieve this goal. This microneedle system was confirmed to successfully deliver the drug to the skin and maintain a one-week drug retention. Furthermore, its powerful therapeutic potency to manage gout was investigated in both acute gouty and chronic gouty models. Besides, the drug co-delivery system could help avoid long-term daily oral colchicine, a drug with a narrow therapeutic index. This system also avoids mass injection of uricase by improving its stability, enhancing the clinical application value of uricase. In general, this two-drug system reduces the dosage of uricase and colchicine and improves the patient's compliance, which has a strong clinical translation.

Objective:To investigate the effect of visceral obesity on the short-term curative effect of Da Vinci robotic-assisted radical resec-tion for rectal cancers.Methods:Clinical and pathological data of patients with rectal cancer undergoing Da Vinci robotic-assisted surgery,admitted to People's Hospital of Zhengzhou University and Cancer Hospital of Zhengzhou University from November 2019 to June 2022 were retrospectively analyzed.Visceral fat area(VFA)≥100 cm2 was used as the standard to define visceral obesity.Patients were categorized in-to visceral and non-visceral obesity groups.The short-term efficacy of the two groups was evaluated,and the influencing factors of post-operative complications were analyzed using univariate and multivariate Logistic regression.Results:Among a total of 169 patients,93 were included in the visceral obesity group and 76 in the non-visceral obesity group.There was no significant difference in the baseline data between the two groups(P>0.05).There was no conversion to laparotomy in the non-visceral obesity group,and the conversion rate was 1.1%(1/93)in the visceral obesity group.The second operation rate was 2.2%(2/93)in the visceral obesity group and 1.3%(1/76)in the non-visceral obesity group with no statistical difference between the two groups.There were no significant differences in the operation dur-ation,intraoperative blood loss,number of lymph node dissections,and total postoperative complication rate between the two groups(P>0.05).Multivariate Logistic regression analysis revealed that an NRS≥3 independently contributed as a risk factor for postoperative com-plications(OR=3.190,95%CI:1.240-8.210,P=0.016).Conclusions:An NRS≥3 is an independent risk factor for complications post-robotic rad-ical rectal cancer surgery.The robotic surgical platform can overcome obesity-related limitations and is equally safe and effective for pa-tients with visceral obesity presenting with rectal cancer.

Hepatocellular carcinoma (HCC) has the features of high incidence rate, low survival rate, poor treatment outcome, and complex pathogenesis. In recent years, many studies have shown that long non-coding RNA (lncRNA) MALAT1 is upregulated in HCC and can promote the proliferation, invasion, and metastasis of HCC cells, and it can also guide the diagnosis, prognostic evaluation, and treatment of HCC in clinical practice. This article reviews the current status of research on lncRNA MALAT1 in HCC and discusses its expression pattern, mechanism of action, and clinical significance in predicting and monitoring the progression of HCC, so as to gain a deep understanding of the role of lncRNA MALAT1 in the progression of HCC. It is pointed out that lncRNA MALAT1 is expected to become a potential biomarker for the diagnosis and prognostic evaluation of HCC and may be used as a therapeutic target in clinical practice.

Objective To evaluate the clinical effect of chronic subdual hematoma between surgical procedure twist drill craniostomy with injecting urokinase into hematoma space and only with twist drill craniostomy.Methods Two hundred and twenty-five patients with chronic subdual hematoma patients who were admitted in the Affiliated Hospital of Yangzhou University from January 2011 to April 2017 were retrospectively analyzed.They were divided into two groups according to the different surgical methods,group A for twist drill craniostomy with injecting urokinase into hematoma space (n =116),group B only for twist drill craniostomy (n =109).Then the postoperative drainage volume and residual hematoma was analyzed by repeated measures,while radiographic grading system and recurrence rates after operation were compared between groups with statistical analysis which was done by ANOVA analysis or non-parametric rank sum test.Results The drainage volume 48 hours after surgery was(52.41 ± 7.86) ml in group A,(28.42 ± 4.46) ml in group B as well.The residual volumes which were calculated at 1 month,3 months after surgery was (23.35 ±4.18) ml and (15.31 ±6.15) ml in group A,comparing the volumes of (46.07 ± 5.96) ml and (25.60 ± 5.03) ml in group B.The radiographic grading system was evaluated by grade 1-4.There were 75(64.7％) cases in grade 1,32(27.6％) cases in grade 2,8(6.9％) cases in grade 3,1 (0.9％) cases in grade 4 of group A,as well as 42(38.5％) cases in grade 1,55(50.5％) cases in grade 2,11 (10.1％) cases in grade 3,1 (0.9％) cases in grade 4 of group B.The rate of recurrence for chronic subdural hematoma was 6.0％ in group A,while it was 15.6％ in group B.These data all had significant statistical difference between the two groups (P ＜ 0.05).Conclusion Twist drill craniostomy might be a safe,effective and mini-massive method for treating chronic subdual hematoma,while injecting urokinase into the hematoma space could significantly reduce the rate of recurrence and decrease the volume of hematoma.

Purpose To explore multi-slice spiral CT (MSCT) in differential diagnosis of esophageal leiomyoma and esophageal carcinoma.Material and Methods Plain chest CT scan and enhanced inspection image of 26 patients with esophageal leiomyoma and 68 patients with esophageal carcinoma at the same term which had been confirmed by surgery and pathology were retrospectively analyzed.Characteristics such as focus size,morphology,density and tumor-air surface,etc were recorded and compared.Results MSCT of esophageal leiomyoma showed uniform density,possible calcification,polylimited influence of esophageal wall,scarcity of depression in focus niche,smooth tumor-air surface,low degree of enhanced amplification,and cerioid expansion of related lumen of larger focus.However,MSCT in esophageal carcinoma was represented by thickened annulus of esophageal wall,no calcification of focus,familiarity of depression in focus niche,rough tumor-air surface and intermediate degree strengthening.Differences of contrast of calcification,polylimited influence of esophageal wall,scarcity of depression in focus niche,smooth tumor-air surface in sophageal leiomyoma with that of esophageal carcinoma were statistically significant (P＜0.05).Conclusion MSCT can accurately identify sophageal leiomyoma and esophageal carcinoma,offering evidence for clinical diagnosis and treatment.
