OBJECTIVE: To investigate the effects of acupuncture on the neurotransmitter levels and gut microbiota in a mouse model of Tourette syndrome (TS). METHODS: Thirty-six male C57/BL6 mice were randomly divided into 4 groups using a random number table method: 3,3'-iminodipropionitrile (IDPN) group, control group, acupuncture group, and tiapride group, with 9 mice in each group. In the IDPN group, acupuncture group, and tiapride group, mice received daily intraperitoneal injections of IDPN (300 mg/kg body weight) for 7 consecutive days to induce stereotyped behaviors. Subsequently, in the acupuncture intervention group, standardized acupuncture treatment was administered for 14 consecutive days to IDPN-induced TS model mice. The selected acupoints included Baihui (DU 20), Yintang (DU 29), Waiguan (SJ 5), and Zulinqi (GB 41). In the tiapride group, mice were administered tiapride (50 mg/kg body weight) via oral gavage daily for 14 consecutive days. The control group, IDPN group, and acupuncture group received the same volume of saline orally for 14 consecutive days. Stereotypic behaviors were quantified through behavioral assessments. Neurotransmitter levels, including dopamine (DA), glutamate (Glu), and aspartate (ASP) in striatal tissue were measured using enzyme-linked immunosorbent assay. Dopamine transporter (DAT) expression levels were additionally quantified through quantitative polymerase chain reaction (qPCR). Gut microbial composition was analyzed through 16S ribosomal RNA gene sequencing, while metabolic profiling was conducted using liquid chromatography-mass spectrometry (LC-MS). RESULTS: Acupuncture administration significantly attenuated stereotypic behaviors, concurrently reducing striatal levels of DA, Glu and ASP concentrations while upregulating DAT expression compared with untreated TS controls (P<0.05 or P<0.01). Comparative analysis identified significant differences in Muribaculaceae (P=0.001), Oscillospiraceae (P=0.049), Desulfovibrionaceae (P=0.001), and Marinifilaceae (P=0.014) following acupuncture intervention. Metabolomic profiling revealed alterations in 7 metabolites and 18 metabolic pathways when compared to the TS mice, which involved various amino acid metabolisms associated with DA, Glu, and ASP. CONCLUSIONS Acupuncture demonstrates significant modulatory effects on both central neurotransmitter systems and gut microbial ecology, thereby highlighting its dual therapeutic potential for TS management through gut-brain axis regulation.

Andrographolide sulfonate (AS) is a sulfonated derivative of andrographolide extracted from Andrographis paniculata (Burm.f.) Nees, and has been approved for several decades in China. The present study aimed to investigate the novel therapeutic application and possible mechanisms of AS in the treatment of rheumatoid arthritis. Results indicated that administration of AS by injection or gavage significantly reduced the paw swelling, improved body weights, and attenuated pathological changes in joints of rats with adjuvant-induced arthritis. Additionally, the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1β in the serum and ankle joints were reduced. Bioinformatics analysis, along with the spleen index and measurements of IL-17 and IL-10 levels, suggested a potential relationship between AS and Th17 cells under arthritic conditions. In vitro, AS was shown to block Th17 cell differentiation, as evidenced by the reduced percentages of CD4⁺ IL-17A⁺ T cells and decreased expression levels of RORγt, IL-17A, IL-17F, IL-21, and IL-22, without affecting the cell viability and apoptosis. This effect was attributed to the limited glycolysis, as indicated by metabolomics analysis, reduced glucose uptake, and pH measurements. Further investigation revealed that AS might bind to hexokinase2 (HK2) to down-regulate the protein levels of HK2 but not glyceraldehyde-3-phosphate dehydrogenase (GAPDH) or pyruvate kinase M2 (PKM2), and overexpression of HK2 reversed the inhibition of AS on Th17 cell differentiation. Furthermore, AS impaired the activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signals in vivo and in vitro, which was abolished by the addition of lactate. In conclusion, AS significantly improved adjuvant-induced arthritis (AIA) in rats by inhibiting glycolysis-mediated activation of PI3K/AKT to restrain Th17 cell differentiation.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Traditional decoction pieces have low efficiency, poor batch-to-batch consistency, and irregular physical form, making it difficult to meet the demands of modern automated production and precise and rapid clinical blending. Therefore, this study aims to develop a new type of granular drinking tablet to meet the demand for high-quality development in the traditional Chinese medicine industry. In the current study, the differences and similarities between the new Lonicerae Japonicae Flos (LJF) granular drinking tablets and the traditional ones were evaluated based on the flowability, the paste rate of the standard soup, the characterization fingerprint, the degree of pasting, the content of active ingredients, the transfer rate, and its traditional antipyretic and anti-inflammatory efficacy, using the traditional LJF decoction piece as a reference. The flowability experiments showed that the flowability of medium-sized granules (10-24 mesh) was significantly better than that of traditional drinking tablets (P < 0.01); the results of the paste rate showed that there was no significant difference between the different particle sizes and the original decoction pieces (P > 0.05), but the small particle sizes (24-65 mesh) had poor decoction clarity and gelatinization; the transfer rate was calculated as chlorogenic acid and luteoloside, and there was no significant difference in the transfer rate between traditional slices and different particle sizes (P > 0.05); the pharmacological results showed that the contents of rat tumor necrosis factor-α (TNF-α), rat interleukin-1β (IL-1β) and rat prostaglandin E₂ (PGE₂), xylene ear swelling inhibition rate and granuloma inhibition rate showed that there was no significant difference between the traditional and new granule decoction pieces (P > 0.05). In this study, by examining the fluidity, paste rate, paste degree, and antipyretic and anti-inflammatory effects of the new granular decoction piece of LJF, it was initially revealed that the new granular drinking tablets of LJF were consistent with the basic properties and pharmacological effects of the commercially available traditional drinking tablets. Still, the new granular tablets were characterized by high utilization rate, homogeneous quality, and ease of clinical transfer, which had a good prospect for application. The animal experiment was approved by the Ethics Committee of the China Academy of Chinese Medical Sciences (approval number. 2022B214).

Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions. The professional guideline is required to guide the standardized and efficient clinical comprehensive evaluation of Chinese patent medicine and further improve the authority and quality of evaluation. In combination with the characteristics of Chinese patent medicine and the latest research achievement at home and abroad,the detailed specifications were formulated from six aspects including design,theme selection,content and index,outcome,application and appraisal,and quality control. The guideline was developed based on the guideline development requirements of China Assoication of Chinese medicine. After several rounds of expert consensus and public consultation,the current version of the guideline has been developed.

Atherosclerosis(AS) is caused by impaired lipid metabolism, which deposits lipids in the intima, causes vascular fibrosis and calcification, and then leads to stiffening of the vascular wall. Hyperlipidemia(HLP) is one of the key risk factors for AS. Based on the theory of "nutrients return to the heart and fat accumulates in the channels", it is believed that the excess fat returning to the heart in the vessels is the key pathogenic factor of AS. The accumulation of fat in the vessels over time and the blood stasis are the pathological mechanisms leading to the development of HLP and AS, and "turbid phlegm and fat" and "blood stasis" are the pathological products of the progression of HLP into AS. Didang Decoction(DDD) is a potent prescription effective in activating blood circulation, removing blood stasis, resolving turbidity, lowering lipids, and dredging blood vessels, with the functions of dispelling stasis to promote regeneration, which has certain effects in the treatment of atherosclerotic diseases. This study employed high-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(HPLC-Q-TOF-MS/MS) to screen the main blood components of DDD, explored the targets and mechanisms of DDD against AS and HLP with network pharmacology, and verified the network pharmacological results by in vitro experiments. A total of 231 blood components of DDD were obtained, including 157 compounds with a composite score >60. There were 903 predicted targets obtained from SwissTargetPrediction and 279 disease targets from GeneCards, OMIM, and DisGeNET, and 79 potential target genes of DDD against AS and HLP were obtained by intersection. Gene Ontology(GO) analysis suggested that DDD presumably exerted regulation through biological processes such as cholesterol metabolism and inflammatory response, and Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis suggested that signaling pathways included lipid and atherosclerosis, insulin resistance, chemo-carcinogenesis-receptor activation, and AGE-RAGE signaling pathways in diabetic complications. In vitro experiments showed that DDD could reduce free fatty acid-induced lipid accumulation and cholesterol ester content in L02 cells and improve cellular activity, which might be related to the up-regulation of the expression of PPARα, LPL, PPARG, VEGFA, CETP, CYP1A1, and CYP3A4, and the down-regulation of the expression of TNF-α and IL-6. DDD may play a role in preventing and treating AS and HLP by improving lipid metabolism and inflammatory response, and inhibiting apoptosis with multi-component, multi-target, and multi-pathway characteristics.

Objective: To evaluate the long-term outcomes, failure patterns and prognostic factors of definitive radiotherapy in patients with cervical esophageal carcinoma (CEC). Methods: We retrospectively reviewed the clinical data of 148 CEC patients who treated with definitive radiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2001 to December 2017. The median radiation dose was 66 Gy (59.4-70 Gy) and 33.1% of patients received concurrent chemotherapy. The Kaplan-Meier method was used to calculate survival rates. The log rank test was used for survival comparison and univariate prognostic analysis. The Cox model was used for multivariate prognostic analysis. Results: The median follow-up time was 102.6 months. The median survival time, 2- and 5-year overall survival (OS) were 22.7 months, 49.9% and 28.3%. The median, 2- and 5-year progression-free survival were 12.6 months, 35.8% and 25.8%. The 2- and 5-year locoregional recurrence-free survival were 59.1% and 50.8%. The 2- and 5-year distant metastases-free survival were 74.6% and 65.9%. Multivariate analysis showed that EQD(2)>66 Gy was the only independent prognostic indicator for OS (P=0.040). The median survival time and 5-year OS rate significantly improved in patients who received EQD(2)>66 Gy than those who received≤66 Gy (31.2 months vs. 19.2 months, 40.1% vs. 19.1%, P=0.027). A total of 87 patients (58.8%) developed tumor progression. There were 50 (33.8%), 23 (15.5%) and 39 (26.4%) patients developed local, regional recurrence and distant metastases, respectively. Eleven patients (7.4%) underwent salvage surgery, and the laryngeal preservation rate for entire group was 93.9%. Conclusions: Definitive radiotherapy is an effective treatment for cervical esophageal carcinoma with the advantage of larynx preservation. Local recurrence is the major failure pattern. EQD(2)>66 Gy is associated with the improved overall survival.

Objective: To investigate the effects of long non-coding RNA RP1-90L14.1 on the proliferation, migration and invasion of prostate cancer LNCaP cells and the expressions of GRIN2A and BACE2. METHODS: Using RT-PCR, we detected the expression of RP1-90L14.1 in LNCaP and LNCaP-AI cells, transiently transfected the RP1-90L14.1 overexpression plasmid (the RP1-90L14.1 group) and vector plasmid (the LNCaP-NC group) into the LNCaP cells, and cultured the two groups of cells with ordinary medium and phenol red-free activated carbon adsorption medium (PRF-ACA). Then we examined the proliferation, migration and invasiveness of the cells by CCK-8 and Transwell, and determined the mRNA and protein expressions of GRIN2A and BACE2 by RT-PCR and Western blot. RESULTS: The expression of RP1-90L14.1 was significantly higher in the LNCaP-AI than in the LNCaP cells (8.49 ± 0.43 vs 2.53 ± 0.95, P < 0.05), and so was that of LNCaP-RP1-90L14.1 in the RP1-90L14.1 than in the LNCaP-NC group after transfection (0.71 ± 0.22 vs 0.02 ± 0.01, P < 0.05). The optical densities (OD) of the cells were 51.95% and 50.69% higher in the RP1-90L14.1 than in the LNCaP-NC group after 72 hours of culture with ordinary medium and phenol red-free ACA (1.22 ± 0.08 vs 0.08 ± 0.05, P < 0.05; 0.79 ± 0.02 vs 0.53 ± 0.05, P < 0.05), and 51.72% and 60.23% higher in the former than in the latter after 96 hours (1.72 ± 0.07 vs 1.13 ± 0.05, P < 0.05; 1.18 ± 0.05 vs 0.73 ± 0.08, P < 0.05). The numbers of the migrating cells cultured with common medium and PRF-ACA were markedly higher in the RP1-90L14.1 than in the LNCaP-NC group after transfection (682.0 ± 42.7 vs 422.0 ± 37.1, P < 0.05; 419.0 ± 42.9 vs 251.0 ± 25.9, P < 0.05), and so were those of the invading cells (507.0 ± 22.2 vs 274.0 ± 19.6, P < 0.05; 352.0 ± 14.1 vs 216.0 ± 14.3, P < 0.05). Statistically significant differences were observed between the RP1-90L14.1 and LNCaP-NC groups in the mRNA and protein expressions of GRIN2A (5.13 ± 0.89 vs 2.09 ± 0.54, P < 0.05; 5.88 ± 0.29 vs 2.03 ± 0.22, P < 0.05) and BACE2 (5.82 ± 0.50 vs 2.53 ± 0.30, P < 0.05; 4.89 ± 0.19 vs 3.37 ± 0.13, P < 0.05). CONCLUSIONS 　lncRNA RP1-90L14.1 may play important roles in the proliferation, migration and invasiveness of prostate cancer cells. RP1-90L14.1 can promote the expressions of GRIN2A and BACE2 and may have an endogenous competitive relation with GRIN2A and BACE2.

【Background】 The aim of this prospective randomized study was to evaluate the feasibility of subtotal thyroidectomy leaving a unilateral remnant based on the upper pole. 【Methods】 Patients who underwent the subtotal thyroidectomy and isthmusectomy leaving either a unilateral remnant based on the upper pole（GroupⅠ ，59 patients）or with the bilateral dorsal thyroid tissue remained（Group Ⅱ，54 patients）were prospectively compared in operation time， blood loss，recurrence，and postoperative complications.【Results】The operation time remained similar between the two groups，but the blood loss，the reoperation time，recurrent laryngeal nerve injury，and recurrence in GroupⅠwere much less than those in Group Ⅱ. In addition ，no postoperative hemorrhage occurred in GroupⅠ. Three patients （5.56%） underwent postoperative hemorrhage in Group Ⅱ. Two patients（3.39%）in GroupⅠand 4 patients（7.40%）in Group Ⅱ experienced transient hypocalcemia.【Conclusion】In terms of blood loss，reoperation time，postoperative complication， and recurrence ，subtotal thyroidectomy with recurrent laryngeal nerves identification and the unilateral superior pole remnant of the gland provides a better outcome than subtotal thyroidectomy with bilateral dorsal thyroid tissue remnant.
