ObjectiveTo observe the clinical effectiveness and safety of She medicine （畲药） Diren Zishen Formula（地稔滋肾方） combined with acupuncture as adjunctive treatment for primary biliary cholangitis with liver and kidney yin deficiency syndrome. MethodsSeventy patients of primary biliary cholangitis with liver and kidney yin deficiency syndrome were randomly divided into a control group and a treatment group， with 35 patients in each group. The control group received oral ursodeoxycholic acid capsules （250 mg per dose， three times daily）. The treatment group received She medicine Diren Zishen Formula oral decoction （one dose daily， 200 ml per dose in the morning and evening， served warm） and acupuncture ［bilateral Sanyingjiao （SP6）， Taichong （LR3）， Ganshu （BL18）， Zusanli （ST36）， Fenglong （ST17）， once daily， 5 consecutive days per week］ in addition to the same treatment as the control group. The treatment duration was three months for both groups. Comparisons were made between the two groups before and after treatment for the following parameters， which were four traditional Chinese medicine （TCM） symptoms scores （skin itching， fatigue， jaundice， and flank pain）， TCM syndrome scores， liver function indicators including aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， gamma-glutamyl transferase （GGT） and total bilirubin （TBiL）， liver fibrosis markers including serum laminin （LN）， serum hyaluronic acid （HA）， serum type Ⅳ collagen （Ⅳ-C） and serum type Ⅲ procollagen （PC-Ⅲ）， and inflammatory factor indicators including serum interleukin-6 （IL-6） and tumor necrosis factor-alpha （TNF-α）. The effectiveness of TCM syndrome between the two groups was compared and safety evaluations were also conducted after treatment. ResultsA total of 32 cases were finally analyzed in the treatment group， while the control group had 31 cases. The total effective rate of TCM syndrome in the treatment group （87.50%， 28/32） was higher than that in the control group （67.74%， 20/31） （P＜0.05）. After treatment， the TCM symptom scores， syndrome scores， liver function， and liver fibrosis markers in both groups signi-ficantly decreased， while in the treatment group， the inflammatory factor indicators decreased after treatment， and more decreases were found than those in the control group （P＜0.05 or P＜0.01）. Both groups had good safety， and no adverse reactions were observed. ConclusionThe combination of She medicine Diren Zishen Formula and acupuncture as an adjunctive treatment for primary biliary cholangitis can significantly improve the clinical effectiveness， improve liver function， reduce inflammatory response， and alleviate liver fibrosis， with good safety.

Objective To investigate the role and mechanism of SR8278,a synthetic antagonist of nuclear receptor subfamily 1 group D member 1(NR1D1),in alleviating the structural and functional impairment of the extraorbital lacrimal glands induced by jet lag in mice.Methods Totally 36 healthy wild C57BL/6J mice aged 8-10 weeks were randomly divid-ed into 3 groups(normal group,jet-lag group,and jet-lag+SR8278 group)after adapting to a circadian rhythm chamber under the 12 h light/12 h dark(12 h/12 h LD)cycle for 2 weeks,with 12 mice in each group.Mice in the normal group were fed in a circadian rhythm chamber in a 12 h LD cycle,mice in the jet-lag group were fed in a 12 h/12 h LD cycle with an 8-hour advanced LD schedule,and mice in the jet lag+SR8278 group were fed in a 12 h/12 h LD cycle with an 8-hour advanced LD schedule and received 25 mg·kg-1 SR8278.At the end of 5 days of intervention,locomotor activity,core body temperature and tear secretion of mice in each group were collected,and the weight of lacrimal gland tissues and size of lacrimal gland cells were measured.Immunohistochemical methods were used for histological evaluation of the extraor-bital lacrimal glands in mice.Lacrimal ribonucleic acid(RNA)was extracted for high-throughput RNA-sequencing analysis containing NR1D1,and the obtained transcriptomic data were used for KEGG and GO functional enrichment analysis.Re-sults Compared with the normal group,the jet-lag group had higher daytime activity,lower nighttime activity,higher daytime core body temperature,and lower nighttime core body temperature,with statistically significant differences(all P＜0.05).Compared with the jet-lag group,the jet-lag+SR8278 group had lower daytime activity,higher nighttime activi-ty,lower daytime core body temperature,and higher nighttime core body temperature,with statistically significant differ-ences(all P＜0.05).Compared with the normal group,the jet-lag group showed a decrease in lacrimal gland weight and tear secretion and an increase in size of lacrimal gland cells,with statistical significance(all P＜0.05);compared with the jet-lag group,the jet-lag+SR8278 group had an increase in lacrimal gland weight and tear secretion and a decrease in size of lacrimal gland cells,with statistical significance(all P＜0.05).Compared with the normal group,the jet-lag group showed a higher expression of NR1D1 in the lacrimal gland at night;compared with the jet-lag group,the jet-lag+SR8278 group showed a lower expression of NR1 D1 in the lacrimal gland at night(both P＜0.05).Bioinformatics analysis showed 947 significantly different genes in the jet-lag group and the jet-lag+SR8278 group,of which 43 are significantly upregulated genes,and 904 are significantly downregulated genes.The Notch signaling pathway has the most significant difference.Conclusion SR8278 effectively enhances the tear secretion function of jet-lagged mice by targeting NR1D1 inhibition.This process may be completed through the Notch signaling pathway.

Background/Aims: The occurrence and development of circular RNAs in gastric cancer (GC) has attracted increasing attention. This study focused on investigating the biological role and molecular mechanism of circ_0043947 in GC. Methods: The expression levels of circ_0043947, miR-384 and CAMP response element binding protein (CREB1) were determined by quantitative real-time polymerase chain reaction or Western blotting. Cell proliferation, migration, and invasion, the cell cycle and apoptosis were determined using a cell counting kit-8 assay, 5-ethynyl-2'-deoxyuridine assay, colony formation assay, wound healing assay, transwell assay, and flow cytometry assay. The interaction between miR-384 and circ_0043947 or CREB1 was verified by dual-luciferase reporter assay and RNA pull-down assay. The in vivo assay was conducted using a xenograft mouse model. Results: Circ_0043947 and CREB1 expression levels were significantly upregulated, whereas miR-384 expression levels were downregulated in GC tissues and cells. Functionally, knockdown of circ_0043947 inhibited cell proliferation, migration and invasion and induced G0/G1 phase arrest and apoptosis in vitro. Circ_0043947 could upregulate CREB1 expression by directly sponging miR-384. Rescue experiments showed that a miR-384 inhibitor significantly reversed the inhibitory effect of si-circ_0043947 on GC progression, and CREB1 overexpression significantly reversed the inhibitory effect of miR-384 mimics on the progression of GC cells. Furthermore, silencing of circ_0043947 inhibited tumor growth in vivo. Conclusions Circ_0043947 acted as an oncogenic factor in GC to mediate GC cell proliferation, migration, and invasion, the cell cycle and apoptosis by regulating the miR-384/CREB1 axis.Circ_0043947 may be a potential target for GC diagnosis and therapy.

Corresponding treatment strategies were adopted according to different main pancreatic duct types, the main pancreatic duct was successfully found, and a support drainage tube was inserted.Conclusion:After linear stapler closure of pancreatic neck, corresponding treatment strategies should be adopted according to the classification of the main pancreatic duct, which would help to improve the success rate of finding the main pancreatic duct and placing a support drainage tube.

The heterogeneity of exhausted T cells (Tex) is a critical determinant of immune checkpoint blockade therapy efficacy. However, few studies have explored exhausted T cell subpopulations in human cancers. In the present study, we examined samples from two cohorts of 175 patients with head and neck squamous cell cancer (HNSCC) by multiplex immunohistochemistry (mIHC) to investigate two subsets of Tex, CD8⁺PD1⁺TCF1⁺ progenitor exhausted T cells (TCF1⁺Tex^prog) and CD8⁺PD1⁺TCF1^- terminally exhausted T cells (TCF1^-Tex^term). Moreover, fresh tumor samples from 34 patients with HNSCC were examined by flow cytometry and immunohistochemistry to further investigate their properties and cytotoxic capabilities and their correlation with regulatory T cells (Tregs) in the tumor immune microenvironment (TIME). mIHC and flow cytometry analysis showed that TCF1^-Tex^term represented a greater proportion of CD8⁺PD1⁺Tex than TCF1⁺Tex^prog in most patients. TCF1⁺Tex^prog produced abundant TNFα, while TCF1^-Tex^term expressed higher levels of CD103, TIM-3, CTLA-4, and TIGIT. TCF1^-Tex^term exhibited a polyfunctional TNFα⁺GZMB⁺IFNγ⁺ phenotype; and were associated with better overall survival and recurrence-free survival. The results also indicated that larger proportions of TCF1^-Tex^term were accompanied by an increase in the proportion of Tregs. Therefore, it was concluded that TCF1^-Tex^term was the major CD8⁺PD1⁺Tex subset in the HNSCC TIME and that these cells favor patient survival. A high proportion of TCF1^-Tex^term was associated with greater Treg abundance.
