Objective:To investigate the risk factors and prognosis of anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis following herpes simplex virus encephalitis (HSE) in children.Methods:A retrospective cohort study was conducted on 83 children with HSE hospitalized at Beijing Children′s Hospital, Capital Medical University, from January 2013 to June 2023. The clinical data, including demographics, clinical manifestations, Glasgow coma scale (GCS) scores, auxiliary examinations, and treatment regimens, were collected. The prognoses of these children were evaluated using the modified Rankin scale (mRS), pediatric cerebral performance category (PCPC) scale, and pediatric quality of life inventory (PedsQL). These children were divided into 2 groups: those who developed secondary anti-NMDAR encephalitis and those who did not. Non-parametric tests were used for intergroup comparisons, and Logistic regression models were applied to identify risk factors for secondary anti-NMDAR encephalitis.Results:Among the 83 children with HSE, 23 children developed secondary anti-NMDAR encephalitis. The secondary anti-NMDAR encephalitis group exhibited a later age of onset compared to the non-secondary group (4.0 (2.2, 7.1) vs. 1.6 (0.8, 5.4) years, Z=2.19, P=0.028), lower GCS scores (8.0 (5.5, 11.5) vs. 14.0 (9.8, 15.0) points, Z=3.74, P<0.001), and worse prognostic outcomes as measured by mRS, PCPC scale and PedsQL (3.0 (2.0, 5.0) vs. 1.0 (0.3, 3.0) points, 3.0 (2.0, 4.0) vs. 2.0 (1.0, 4.0) points, 52.0 (17.0, 67.0) vs. 86.5 (53.3, 97.5) points, Z=3.48, 3.36, 3.09, all P<0.01). Logistic regression analysis identified lower GCS scores during HSE as an independent risk factor for the secondary anti-NMDAR encephalitis ( OR=0.82, 95% CI 0.72-0.94, P=0.003). Conclusion:For the children with HSE who present low GCS scores, regular follow-ups are imperative in order to monitor for the potential development of anti-NMDAR encephalitis, thus facilitating early intervention and improving clinical outcomes.

Objective:To formulate the audit standards of Chinese patent medicine prescriptions, and provide reference for rational prescriptions of Chinese patent medicine.Methods:A three-level evidence system for prescription review of Chinese patent medicine was established according to the national regulatory documents, drug labels, relevant guidelines, and expert consensuses. The catalog of Chinese patent medicines in Army Medical Center of the People′s Liberation Army was integrated and classified, preliminary review criteria including indications, drug selection, usage and dosage, and combination drugs was established and submitted to clinical experts of traditional Chinese medicine for review and revision, and finally the prescription review standard was confirmed.Results:The Chinese patent medicine catalog of the Medical Center contained 218 drugs, which were divided into 23 kinds according to efficacy and 17 kinds according to dosage forms. The prescription review standards of Chinese patent medicine were as follows. (1) Indications: both traditional Chinese medicine and Western medicine diagnosis were required. (2) Drug selection: 37 kinds of Chinese patent medicines were marked as forbidden for pregnant women in the labels, and 16 kinds were not marked but contained forbidden ingredients; 4 kinds were marked with caution for patients with liver dysfunction, and 24 kinds were not marked but contained ingredients with caution; 2 kinds of Chinese patent medicines were marked with caution for patients with renal insufficiency, and 9 kinds were not marked but contained ingredients with caution. (3) Usage and dosage: the usage and dosage rules of Chinese patent medicines for children, the elderly and patients with liver and kidney dysfunction were formulated. (4) Combined medication: 5 and 21 kinds of Chinese patent medicines were marked as "highly toxic" and "toxic" in the labels, respectively, 11 kinds of Chinese patent medicines contained incompatible ingredients of "Shibafan" (eighteen antagonisms) and "Shijiuwei (nineteen incompatibilities), and a new review scale for repeated use of Chinese patent medicine was developed.Conclusions:Based on the existing evidence-based medicine, the evidence system of prescription review of Chinese patent medicine is established, the prescription review standards of Chinese patent medicine prescription based on the pharmaceutical interaction mode is formulated and constructed.

Objective    To investigate the clinical characteristics of thoracic esophageal-gastric cancer (TEGC) and the safety and effectiveness of secondary reconstruction of thoracic and gastrointestinal tract after esophageal and preventriculus cancer (esophagogastric junction) surgery. Methods    The clinical data of 353 patients with esophageal and preventriculus cancer who underwent endoscopic review from July 2007 to December 2019 were retrospectively analyzed. A total of 31 (8.78%) patients with relapsed or recurrent TEGC were found, including 24 males and 7 females with a mean age of 58.5 years (range: 42 to 68 years). There were 18 (58.06%) patients of adenocarcinoma and 13 (41.94%) squamous cell carcinoma. All patients underwent TEGC resection and secondary reconstruction of thoracic gastrointestinal tract. Thoracoabdominal computed tomography (CT) and upper gastrointestinal imaging (GI) were performed during follow-up, and gastroscopy was performed for suspected patients. All the patients were followed-up till death or December 30, 2019. The survival rate was calculated by Kaplan-Meier method, and the survival was analyzed using the log-rank test. Results    Thirty-one patients underwent thoracic esophagectomy and gastric cancer resection, and then reconstruction of the thoracic and gastrointestinal tract. Eight patients underwent residual gastroesophageal thoracic anastomosis, 13 patients colon esophagectomy, 6 patients jejunal esophagectomy (1 patient esophago-jejunal Roux-en-Y anastomosis), and 4 patients cervical esophagogastric anastomosis. The mean operation time and intraoperative blood loss were 404.8 (340-475) min and 378.4 (180-620) mL. The postoperative complications ocurred in 4 patients, including 3 patients of pulmonary infection and 1 patient of cervical incision infection. The mean hospital stay was 17.1 (14-21) d. All patients were followed up, the median survival time of 11 patients in stage Ⅰ-ⅡA was 25 (19.8-35.0) months and 20 patients in stage ⅡB-ⅢA was 16 (12.5-19.5) months. There was a significant difference between the two groups (χ2=7.840 8, P<0.01). Conclusion    Postoperative relapsed and recurrent TEGC occurs after the surgery for esophageal and preventriculus cancers, most of which are caused by metachronous gastric cancer or residual esophageal carcinoma recurrence which leads to invasion of the thoracic and gastric wall. Regular endoscopic review is the main method after operation. It is technically safe and feasible to reconstruct the thoracic and esophageal digestive tract in patients with TEGC after reoperation, which can benefit the survival of patients.

Objective: To construct the expression plasmid of a novel gene human NBEAL1 (neurobeachin like 1), and to study its relationship with the pathological grades of glioma. Methods: Total RNA of human glioma cell line U251 was extracted. NBEAL1 expression plasmid pGEX-KG/NBEAL1 was constructed and transferred into E. coli BL21. Recombinant NBEAL1 protein was induced by IPTG and further purified by GST affinity chromatographic column. The purity of recombinant NBEAL1 protein was examined by Western blotting analysis. A NBEAL1 protein specific monoclonal antibody was prepared and was used to study the relationship of NBEAL1 expression with pathological grades of glioma. Results: The NBEAL1 gene fragment was successfully cloned into pGEX-KG expression plasmid and verified by DNA sequencing. The recombinant NBEAL1 protein was expressed in inclusion bodies, with a yield of more than 30% of total bacterial proteins; the purity of purified NBEAL1 protein was above 95%. Western blotting analysis confirmed that the purified protein containing GST tag and NBEAL protein. NBEAL1 protein was lowly expressed in normal brain tissues and highly expressed in low grade glioma tissues; and the expression of NBEAL1 decreased with the increase of glioma malignancy. Conclusion: The NBEAL1 protein has been successfully cloned, expressed and purified. NBEAL1 protein expression in glioma tissues is negatively associated with the pathological grades of glioma.
