Objective To summarize common antibody types and clinical symptoms during the acute phase of autoimmune encephalitis （AE）， to investigate the influencing factors for delayed diagnosis， and ultimately to reduce misdiagnosis rate， improve the prognosis of patients， and reduce medical expenses. Methods Antibody-positive AE patients who were diagnosed in 7 grade A tertiary hospitals from different provinces in China from 2018 to 2022 were enrolled， and related clinical data were collected. Univariate and multivariate logistic regression analyses were used to identify the influencing factors for delayed diagnosis （time from symptom onset to confirmed diagnosis >4 weeks）， and the receiver operating characteristic curve and the nomogram predictive model were constructed. The calibration curve and the Hosmer-Lemeshow goodness-of-fit test were used to assess the degree of calibration of the nomogram predictive model， and a decision curve analysis was used to assess the clinical effectiveness of the nomogram. Results A total of 394 AE patients who met the inclusion and exclusion criteria were enrolled， among whom there were 226 male patients （57.4%）. The median length of hospital stay was 16（12，23） days for all patients， and 89 patients （22.6%） had a history of treatment in the intensive care unit. Of all patients，171（43.4%） experienced delayed diagnosis.Age（OR=1.016）， memory impairment （OR=2.337）， hallucination （OR=1.665）， and sleep disorders（OR=1.818） were independent risk factors for delayed diagnosis.Of all patients，329（83.5%） were misdiagnosed before the confirmed diagnosis of AE. During the acute phase， 332 patients（84.3%）presented with psychiatric and behavioral abnormalities， 289（73.4%） had symptomatic epilepsy， 258（65.5%） had cognitive impairment，and 154（39.1%） had sleep disorders. The CASE scale score was（9.4±4.1） on admission. Electroencephalographic abnormalities were observed in 294 patients（74.6%）， and magnetic resonance imaging abnormalities were detected in 210 patients（53.3%）， with lesions mainly located in the temporal and frontal lobes. Conclusion Delayed diagnosis of AE is common in China， which is mainly associated with an old age， and memory impairment， hallucination， and sleep disorders are also risk factors for delayed diagnosis.

Sudden unexpected death in epilepsy (SUDEP) refers to the sudden, unexpected and unexplained death of epilepsy patients, which is an important reason for the significant increase of the death risk of epilepsy patients. The risk factors of SUDEP are related to poor control of seizures, nocturnal seizures, prone position, antiepileptic drugs, comorbidity, etc. Epilepsy death caused by SUDEP has become a major public health problem. The latest progress in neuropathology and cardiopulmonary pathology of SUDEP was reviewed in this article.

Objective:To evaluate the efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-TSCPC) for refractory glaucoma.Methods:A prospective multicenter observational case series study was conducted.A total of 63 refractory glaucoma patients (67 eyes) who underwent MP-TSCPC treatment were enrolled at Zhongshan Ophthalmic Center, Sun Yat-sen University, Chengdu First People's Hospital (Chengdu Integrated TCM& Western Medicine Hospital), and Changsha Aier Eye Hospital from August 2022 to April 2023.Among these cases, there were 40 eyes (59.7%) with unreduced intraocular pressure (IOP) after glaucoma surgery, 4 eyes (6.0%) with secondary glaucoma after vitrectomy, 2 eyes (3.0%) with secondary glaucoma after keratoplasty, 8 eyes (11.9%) with neovascular glaucoma, 3 eyes (4.5%) with secondary glaucoma due to iridocorneal endothelial syndrome, 6 eyes (9.0%) with primary open-angle glaucoma and 4 eyes (6.0%) with primary angle-closure glaucoma.Best corrected visual acuity (BCVA) was measured using the ETDRS chart and the IOP was measured using the Goldmann applanation tonometry before and 6 months after the surgery.The usage of anti-glaucoma medications before and after surgery and postoperative complications were recorded.Surgical success rate was calculated and surgical success was defined as an IOP reduction of more than 20% from baseline or a reduction in the number of ocular hypotensive medications with no change in IOP.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Zhongshan Ophthalmic Center, Sun Yat-sen University (No.2022KYPJ225).Written informed consent was obtained from each subject.Results:There was a statistically significant overall difference in IOP at different time points before and after surgery ( F=60.10, P<0.001), and the IOP at different time points after surgery was significantly lower than that before surgery, with statistically significant differences (all at P<0.001).IOP reduction at 6 months after surgery was (43.7±20.7)%.The number of anti-glaucoma medications used postoperatively was 2(0, 3) types, which was significantly less than the 3(2, 3) types used preoperatively ( Z=-2.70, P=0.007).The 6-month postoperative BCVA (LogMAR) was 1.40(0.52, 2.70), which showed no significant change compared to the preoperative 1.40(0.70, 2.70) ( Z=-0.10, P=0.952).The surgical success rate was 83.6%(56/67) at 6 months postoperatively.Postoperative complications included mydriasis (11/67), conjunctival hemorrhage (11/67), mild anterior chamber inflammation (1/67), mild ciliary body detachment (3/67), local choroidal detachment (1/67), and cystoid macular edema (1/67), all of which were reversible after treatment. Conclusions:MP-TSCPC appears to be a safe and effective treatment option for refractory glaucoma.

Objective To analyze the relationship between expression levels of long non-coding RNA(LncRNA)LINC00342 and microRNA-203a-3p(miR-203a-3p)in colorectal cancer tissue and the prognosis of patients within 5 years after surgery.Methods Samples of colorectal cancer tissue and paracancer tissue of 133 patients with colorectal cancer were collected.Expression levels of LncRNA LINC00342 and miR-203a-3p were detected by fluorescence quantitative PCR.Survival and death were recorded after 5 years of follow-up.The LncRNA LINC00342 and miR-203a-3p expressions and clinicopathological parameters in patients under different conditions were compared.The correlation between expressions of LncRNA LINC00342 and miR-203a-3p in colorectal cancer tissue was analyzed,and their predictive value for the prognosis was also analyzed.Results The expression level of LncRNA LINC00342 was higher in colorectal cancer tissue than that in paracancer tissue,and the expression level of miR-203a-3p was lower in colorectal cancer tissue than that in paracancer tissue(P＜0.05).The expression levels of LncRNA LINC00342 and miR-203a-3p in colorectal cancer tissue were negatively correlated(P＜0.05).The proportion of patients with low tumor differentiation,TNM stage Ⅲ and lymph node metastasis were higher in the LncRNA LINC00342 high expression group and the miR-203a-3p low expression group than those in the LncRNA LINC00342 low expression group and the miR-203a-3p high expression group,respectively(P＜0.05).The 5-year overall survival rate after operation was lower in the LncRNA LINC00342 high expression group and the miR-203a-3p low expression group(P＜0.05).The proportion of patients with low tumor differentiation,TNM stage Ⅲ,lymph node metastasis,and higher expression level of LncRNA LINC00342 were higher in colorectal cancer tissue of the death group than those in the survival group,and the expression level of miR-203a-3p was lower than that in the survival group(P＜0.05).Low tumor differentiation,TNM stage Ⅲ,lymph node metastasis,high expression of LncRNA LINC00342 and low expression of miR-203a-3p were independent risk factors for death within 5 years after colorectal cancer surgery(P＜0.05).The combined predictive value of LncRNA LINC00342 and miR-203a-3p for prognosis was greater than that of individual prediction.Conclusion LncRNA LINC00342 is higher expressed and miR-203a-3p is lower expressed in colorectal cancer tissue,and the combined detection of the two is expected to become a clinical evaluation indicator for predicting postoperative survival.

Objective:To investigate the relationship between the cerebral small vascular disease (CSVD) total burden and the imaging markers and the degree of unilateral middle cerebral artery (MCA) stenosis.Methods:The study was a cross-sectional study. Clinical and imaging data of patients with chronic unilateral MCA stenosis who underwent multimodal MRI from October 2015 to January 2019 in the First Medical Center of PLA General Hospital were retrospectively analyzed. A total of 261 patients were included, 187 males and 74 females. According to the degree of MCA stenosis, the patients were divided into 102 cases in severe stenosis-occlusion group (stenosis degree ≥70%) and 159 cases in mild-moderate stenosis group (stenosis degree <70%). CSVD imaging marker scores (including white matter hyperintensity, perivascular space, cerebral microbleed, and lacune of presumed vascular origin) were assessed according to the ?standards for reporting vascular changes on neuroimaging 1 in the 2 groups, and the CSVD total burden score was calculated. Mann-Whitney U test was used to compare the indicators between the two groups, and the CSVD total burden score and imaging marker scores were ultimately included in a multifactorial binary logistic regression to assess the association of CSVD imaging markers with severe stenosis-occlusion of the MCA after adjusting for vascular risk factors (age, gender, drinking, smoking, hypertension, hyperlipidemia, atrial fibrillation and coronary heart disease). Results:There were significant differences in the CSVD total burden, centrum semiovale perivascular space and lacune of presumed vascular origin score between the mild-to-moderate stenosis group and the severe stenosis-occlusion group (all P<0.05), and none of the differences in the remaining imaging marker scores were statistically significant (all P>0.05). Multivariate binary logistics regression analysis showed CSVD total burden score ( OR=1.300, 95% CI 1.047-1.613, P=0.017), centrum semiovale perivascular space score ( OR=2.099, 95% CI 1.540-2.860, P<0.001) and lacune of presumed vascular origin score ( OR=2.609, 95% CI 1.294-5.261, P=0.007) were independent associated with severe stenosis-occlusion of MCA. Conclusion:The higher CSVD total burden score, centrum semiovale perivascular space score and lacune of presumed vascular origin score are associated with severe stenosis-occlusion of MCA.

Objective:To evaluate the feasibility, safety and efficacy of indocyanine green (ICG) fluorescence imaging navigation combined with modified pancreaticogastrostomy in laparoscopic duodenum-preserving pancreatic head resection.Methods:The clinical data of 14 patients undergoing laparoscopic duodenum-preserving pancreatic head resection with indocyanine green fluorescence navigation technique combined with modified pancreaticogastrostomy from January 2019 to January 2022 in the Department of Hepatobiliary and Pancreatic Surgery, the First Hospital of Hebei Medical University were retrospectively analyzed, including 4 males and 10 females, aged (40.6±7.1) years. The operation time, intraoperative blood loss, postoperative complications and follow-up were recorded.Results:All 14 operations were successfully completed, and there was no intraoperative ICG allergic reaction. The intraoperative ICG staining facilitated the identification of common bile duct. The operation time was (325.71±23.00) min, and the time of modified pancreaticogastrostomy was (18.32±1.52) min. Intraoperative blood loss was 200 (150, 300) ml. There were no case of intraoperative blood transfusion. Postoperative complications include three cases of grade A pancreatic fistula, one of biliary fistula, and one of biliary stricture. All patients were followed up for one to 18 months, and the median follow-up time was 10 months. One patient had intermittent fever after operation. Magnetic resonance cholangiopancreatography showed biliary stricture in one patient one month after operation, which was managed by endoscopic biliary stent implantation.Conclusion:Indocyanine green fluorescence navigation is safe and feasible in laparoscopic duodenum-preserving pancreatic head resection. Combined with modified pancreaticogastrostomy, it helps skip the jejunal anastomosis and improve the efficiency of surgery.

Objective:To summarize the clinical and neurophysiological characteristics of epilepsy with blink inducing.Methods:The patients with epilepsy with blink test positive who received 24 h-video-electroencephalography (24 h-VEEG) monitoring from May 2017 to May 2022 in the Xijing Hospital, the Air Force Military Medical University were enrolled. Their clinical and electrophysiological characteristics were studied and they were followed up to observe their prognosis.Results:A total of 42 patients with epilepsy with blink test positive were collected, 1 of whom was lost to follow-up. The remaining 41 patients included 18 males (44%) and 23 females (56%), whose age was 3 to 12 (8.1±2.6) years. Self-limited epilepsy with centrotemporal spikes (SeLECTS) was diagnosed in 35 patients, self-limited epilepsy with autonomic seizures in 3, and developmental epileptic encephalopathy with spike-and-wave activation in sleep in 3, respectively. The electrical status epilepticus during sleep (ESES) was found in 31 patients (76%), whereas 10 (24%) without ESES. Thirty-two patients experienced 24 h-VEEG monitoring more than twice, and 23 of them were seizure free, of whom blink inducing disappeared in 14 patients and existed in 9 in the last 24 h-VEEG monitoring. Among the 9 patients who were not seizure free, blink inducing disappeared in 3 patients and remained in 6. There was no statistically significant difference between the two groups ( P>0.05). The age of the patients whose blink inducing disappeared in the last 24 h-VEEG monitoring after treatment was (11.3±3.1) years. Meanwhile the age of the patients whose blink inducing remained was (9.1±2.3) years, and the difference between the two groups was statistically significant ( t=2.254, P=0.030). Conclusions:Blink inducing is highly age-dependent and common in self-limited focal epilepsy and developmental epileptic encephalopathy, especially in SeLECTS. Moreover, patients with ESES are more likely to be blink test positive. There was no correlation between blink inducing and seizure outcome.

Helicobacter pylori （Hp）， a spiral-shaped microaerophilic Gram-negative bacterium that has been classified as a class Ⅰ carcinogen by the World Health Organization， is associated with a variety of digestive system diseases. With the popularization of antibiotic therapy， Hp resistance has become the main reason for the failure of the eradication treatment of Hp. A variety of Chinese medicines have been proved to have anti-Hp effects， which are expected to serve as new options for the eradication of Hp. By reviewing the recent literature in China and abroad， we summarized the understanding of Chinese medicines in the treatment of Hp infection and elaborated on the mechanisms from two aspects： direct killing and indirect inhibition. On the one hand， Chinese medicines can directly kill Hp by inhibiting the growth， respiration， and metabolism of Hp， destroying the morphological structure of Hp， and inhibiting the formation of Hp biofilm. On the other hand， Chinese medicines can inhibit Hp by reducing Hp adhesion and colonization， regulating Hp-caused immune response， inhibiting Hp-caused inflammation， and alleviating the Hp-caused oxidative stress and gastric mucosal injury. Specifically， the indirect inhibition of Hp can be achieved via the following ways. Chinese medicines can reduce Hp adhesion and colonization by reducing Hp motility， inhibiting urease activity and the expression of related genes， and decreasing the production of adhesion proteins. They can regulate the Hp-caused immune responses by enhancing the immune protective response， modulating lysosomal function and immune cytokines， avoiding the immune evasion of Hp， and maintaining the balance between immunity and inflammation. Chinese medicines can inhibit Hp-caused inflammatory responses by inhibiting the release of inflammatory cytokines， down-regulating the expression of virulence factors， and regulating the targets and signaling pathways in the treatment of inflammation. In addition， Chinese medicines can alleviate the Hp-caused oxidative stress and gastric mucosal injury by improving the activities of antioxidant enzymes and oxidases， regulating the generation of reactive oxygen species and reactive nitrogen， and inhibiting inflammatory mediators. This article systematically introduces the mechanisms of Chinese medicines against Hp， aiming to provide a theoretical and scientific basis for the research and clinical application of Chinese medicines against Hp.

ObjectiveTo observe the efficacy and safety of Huashi Runzao prescription for patients with primary Sjögren's syndrome （pSS） of combined dryness and dampness pattern. MethodA total of 105 eligible patients were randomized into the experimental group （65 cases） and control group （40 cases）， and they were respectively treated with Huashi Runzao prescription and hydroxychloroquine for 12 weeks. Visual Analogue Scale （VAS） was employed to assess the symptoms. The symptoms of dryness， fatigue， and pain， European League Against Rheumatism （EULAR） Sjögren's Syndrome Patient Reported Index （ESSPRI）， EULAR Sjögren's syndrome disease activity index （ESSDAI）， and immune inflammatory indicators before and after treatment were compared between the two groups， and adverse reactions were observed. ResultAfter treatment， the ESSPRI score was lower than that before treatment in the experimental groups （P<0.01） and was lower in the experimental group than in the control group （P<0.05）. The VAS scores of dry mouth， dry eyes， overall dryness， fatigue， and pain in the experimental group decreased compared with those before treatment （P<0.01）， and the experimental group had lower VAS scores of dry mouth and overall dryness than the control group （P<0.01）. After treatment， the ESSDAI score of both groups decreased compared with that before treatment （P<0.05， P<0.01）， but there was no significant difference between the groups. After treatment， the level of immunoglobulin M （IgM） decreased （P<0.01） and the level of complement C3 increased （P<0.01） in the experimental group， while the level of complement C3 decreased in the control group （P<0.05）. There was no significant difference in the laboratory indexes between groups. During the treatment， stomachache occurred to one case in the experimental group， which was alleviated after the treatment， and no adverse reaction was observed in the control group. According to the chi-square test， the occurrence of adverse reactions was insignificantly different between the two groups. ConclusionHuashi Runzao prescription can alleviate the symptoms of dryness， fatigue， and pain， and reduce disease activity without associated side effects in pSS patients with combined dampness and dryness pattern.
