The Simultaneous Treatment of Pulse and Syndrome of Water Qi Disease chapter of Synopsis of Golden Chamber is regarded as one of its most challenging sections. Although nominally focused on water qi disease, this chapter also discusses yellowish sweating disease, qifen disease, and other diseases. This multiplicity of topics led to the misconception that all these diseases are water qi diseases, complicating the diagnosis and treatment strategies. By distinguishing water qi as both a pathogenic factor and a disease entity, this paper redefines the concept, linking it to the abnormal accumulation of liquid and gaseous water in the body, akin to the disrupted water cycle of the nature. It demonstrates that ZHANG Zhongjing recognizes the primary syndrome, pathogenesis, and therapeutic principles of water qi disease from the generation, aggregation, and dissipation of vaporous water. The study further differentiates water qi disease, yellowish sweating disease, and qifen disease as distinct entities. An analysis of their etiology, pathogenesis, syndromes, and treatment approaches establishes their independence while exploring their interrelations. Moreover, the relationships among the qifen, xuefen, and water phase diseases are clarified. ZHANG Zhongjing′s discussion in the Simultaneous Treatment of Pulse and Syndrome of Water Qi Disease identifies the three diseases around the three " disease of water phase." The clarification of the concepts and relationships of the diseases in the Simultaneous Treatment of Pulse and Syndrome of Water Qi Disease will help to systematically and thoroughly elucidate ZHANG Zhongjing′s principles and thoughts on identifying and treating water qi disease.

BACKGROUND: Growing evidence suggests that long non-coding RNAs (lncRNAs) exert pivotal roles in fostering chemoresistance across diverse tumors. Nevertheless, the precise involvement of lncRNAs in modulating chemoresistance within the context of gallbladder cancer (GBC) remains obscure. This study aimed to uncover how lncRNAs regulate chemoresistance in gallbladder cancer, offering potential targets to overcome drug resistance. METHODS: To elucidate the relationship between gemcitabine sensitivity and small nucleolar RNA host gene 1 ( SNHG1 ) expression, we utilized publicly available GBC databases, GBC tissues from Renji Hospital collected between January 2017 and December 2019, as well as GBC cell lines. The assessment of SNHG1, miR-23b-3p, and phosphatase and tensin homolog (PTEN) expression was performed using in situ  hybridization, quantitative real-time polymerase chain reaction, and western blotting. The cell counting kit-8 (CCK-8) assay was used to quantify the cell viability. Furthermore, a GBC xenograft model was employed to evaluate the impact of SNHG1 on the therapeutic efficacy of gemcitabine. Receiver operating characteristic (ROC) curve analyses were executed to assess the specificity and sensitivity of SNHG1. RESULTS: Our analyses revealed an inverse correlation between the lncRNA SNHG1 and gemcitabine resistance across genomics of drug sensitivity in cancer (GDSC) and Gene Expression Omnibus (GEO) datasets, GBC cell lines, and patients. Gain-of-function investigations underscored that SNHG1 heightened the gemcitabine sensitivity of GBC cells in both in vitro and in vivo  settings. Mechanistic explorations illuminated that SNHG1 could activate PTEN -a commonly suppressed tumor suppressor gene in cancers-thereby curbing the development of gemcitabine resistance in GBC cells. Notably, microRNA (miRNA) target prediction algorithms unveiled the presence of miR-23b-3p binding sites within SNHG1 and the 3'-untranslated region (UTR) of PTEN . Moreover, SNHG1 acted as a sponge for miR-23b-3p, competitively binding to the 3'-UTR of PTEN , thereby amplifying PTEN expression and heightening the susceptibility of GBC cells to gemcitabine. CONCLUSION The SNHG1/miR-23b-3p/PTEN axis emerges as a pivotal regulator of gemcitabine sensitivity in GBC cells, holding potential as a promising therapeutic target for managing GBC patients.

Various chromatographic methods were comprehensively applied to study the chemical composition of the ethyl acetate extract from Aucklandiae Radix. The structures of all compounds were identified by analyzing their physicochemical properties and using spectroscopic methods. Two new sesquiterpenoids, named auclappsines A and B(1 and 2) were isolated and identified. Through in vitro high content screening and with the use of a guggulsterone-induced L02 cells, the effects of 1 and 2 on farnesoid X receptor(FXR) protein expression were investigated. The results showed that 1 had a significant FXR activation effect, providing a scientific basis for the development of drugs for the treatment of liver and gallbladder diseases.

OBJECTIVE: To investigate possible associations between physical function assessment scales, such as Short Physical Performance Battery (SPPB) and Berg Balance Scale (BBS), with all-cause mortality in acute decompensated heart failure (ADHF) patients. METHODS: A total of 108 ADHF patients were analyzed from October 2020 to October 2022, and followed up to May 2023. The association between baseline clinical characteristics and all-cause mortality was analyzed by univariate Cox regression analysis, while for SPPB and BBS, univariate Cox regression analysis was followed by receiver operating characteristic curves, in which the area under the curve represented their predictive accuracy for all-cause mortality. Incremental predictive values for both physical function assessments were measured by calculating net reclassification index and integrated discrimination improvement scores. Optimal cut-off value for BBS was then identified using restricted cubic spline plots, and survival differences below and above that cut-off were compared using Kaplan-Meier survival curves and the log-rank test. The clinical utility of BBS was measured using decision curve analysis. RESULTS: For baseline characteristics, age, female, blood urea nitrogen, as well as statins, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, or angiotensin receptor-neprilysin inhibitors, were predictive for all-cause mortality for ADHF patients. With respect to SPPB and BBS, higher scores were associated with lower all-cause mortality rates for both assessments; similar area under the curves were measured for both (0.774 for SPPB and 0.776 for BBS). Furthermore, BBS ≤ 36.5 was associated with significantly higher mortality, which was still applicable even adjusting for confounding factors; BBS was also found to have great clinical utility under decision curve analysis. CONCLUSIONS BBS or SPPB could be used as tools to assess physical function in ageing ADHF patients, as well as prognosticate on all-cause mortality. Moreover, prioritizing the improvement of balance capabilities of ADHF patients in cardiac rehabilitation regimens could aid in lowering mortality risk.

G protein-coupled receptor (GPR) 40, as one of GPRs family, plays a potential role in regulating glucose and lipid metabolism. To study the effect of GPR40 novel agonist SZZ15-11 on hyperglycemia and hyperlipidemia and its potential mechanism, spontaneous type 2 diabetic KKA^y mice, human hepatocellular carcinoma HepG2 cells and murine mature adipocyte 3T3-L1 cells were used. KKA^y mice were divided into four groups, vehicle group, TAK group, SZZ (50 mg·kg^-1) group and SZZ (100 mg·kg^-1) group, with oral gavage of 0.5% sodium carboxymethylcellulose (CMC), 50 mg·kg^-1 TAK875, 50 and 100 mg·kg^-1 SZZ15-11 respectively for 45 days. Fasting blood glucose, blood triglyceride (TG) and total cholesterol (TC), non-fasting blood glucose were tested. Oral glucose tolerance test and insulin tolerance test were executed. Blood insulin and glucagon were measured via enzyme-linked immunosorbent assay (ELISA). After mice′s execution, liver tissue was harvested to test TG and TC content. Then pathological morphology of liver was observed through hematoxylin-eosin (HE) staining, and the lipid metabolism relative signal pathway was analyzed by Western blot and RT-PCR. The experiments were approved by the Institutional Animal Care and Use Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College. At the same time, Akt phosphorylation level in HepG2 cells and adiponectin in 3T3-L1 cells treated with TNFα were measured with Western blot. The results show that SZZ15-11 not only decreased blood glucose and lipid, improved insulin sensitivity, but also increased fasting blood glucagon and promoted insulin secretion after glucose loading in KKA^y mice. Additionally, SZZ15-11 alleviated hepatic steatosis and liver dysfunction in KKA^y mice. In liver tissue, SZZ15-11 increased AMPKα phosphorylation level and cholesterol metabolism relative gene Abcg8 transcription. In HepG2 cells, SZZ15-11 increased Akt phosphorylation level. In adipocyte 3T3-L1, SZZ15-11 recovered the decreased adiponectin expression by TNFα. This study proved that GPR40 agonist SZZ15-11 could be a candidate compound for regulating glucolipid metabolic disorder.

Objective To observe the levels of serum thymidine kinase 1(TK1)and secreted protein Dikkopf-1(DKK1)in patients with advanced non-small cell lung cancer(NSCLC),and analyze the relation-ship between serum TK1,DKK1 and the prognosis of NSCLC.Methods This study adopted a prospective co-hort study method,a total of 91 chemotherapy patients with advanced NSCLC admitted in Jinshan Branch of Shanghai Sixth People's Hospital from January 2020 to June 2021 were enrolled as the research objects.All patients received the detection of serum TK1 and DKK1 on admission,completed 4 chemotherapy cycles in Jinshan Branch of Shanghai Sixth People's Hospital and were followed up for 3 months.The disease remission rate was evaluated according to the relevant standards.The patients with complete remission and partial re-mission were included in the good prognosis group,and those with the stable and progressive lesions were in-cluded in the poor prognosis group.The levels of serum TK1 and DKK1 were compared between the two groups.Logistic regression was used to analyze the relationship between the levels of serum TK1 and DKK1 and the prognosis of patients with advanced NSCLC.Results Among 91 patients with advanced NSCLC who received chemotherapy,threre were 58 cases(63.74％)in the good prognosis group,and 33 cases(36.26％)in the poor prognosis group.The levels of serum carcinoembryonic antigen(CEA),TK1 and DKK1 in the poor prognosis group were higher than those in the good prognosis group(P＜0.05).Logistic regression anal-ysis showed that the high levels of serum TK1 and DKK1 were the influencing factors of poor prognosis in pa-tients with advanced NSCLC(OR＞1,P＜0.05).The receiver operating characteristic curve was drawn,and the results showed that the area under the curve of serum TK1,DKK1 alone and combined for predicting the poor prognosis in patients with advanced NSCLC was＞0.700,all of which had certain predictive value,and the predictive value of the combined detection was the highest.Conclusion The abnormal increase of serum TK1 and DKK1 levels may indicate a high risk of poor prognosis in patients with advanced NSCLC.Early monito-ring of serum TK1 and DKK1 levels in patients has certain positive significance for predicting and evaluating the prognosis of patients.

Objective:Trigeminal neuralgia(TN)is a severe chronic neuropathic pain that mainly affects the distribution area of the trigeminal nerve with limited treating efficacy.There are numerous treatments for TN,but currently the main clinical approach is to suppress pain by carbamazepine(CBZ).Brain-derived neurotrophic factor(BDNF)is closely related to chronic pain.This study aims to determine the effects of CBZ treatment on BDNF expression in both the trigeminal ganglion(TG)and serum of TN via a chronic constriction injury of the infraorbital nerve(ION-CCI)rat model. Methods:The ION-CCI models were established in male Sprague-Dawley rats and were randomly divided into a sham group,a TN group,a TN+low-dose CBZ treatment group(TN+20 mg/kg CBZ group),a TN+medium-dose CBZ treatment group(TN+40 mg/kg CBZ group),and a TN+high-dose CBZ treatment group(TN+80 mg/kg CBZ group).The mechanical pain threshold in each group of rats was measured regularly before and after surgery.The expressions of BDNF and tyrosine kinase receptor B(TrkB)mRNA in TGs of rats in different groups were determined by real-time PCR,and the expression of BDNF protein on neurons in TGs was observed by immunofluorescence.Western Blotting was used to detect the protein expression of BDNF,TrkB,extracellular regulated protein kinases(ERK),and phospho-extracellular regulated protein kinases(p-ERK)in TGs of rats in different groups.The expression of BDNF in the serum of rats in different groups was detected by enzyme-linked immunosorbent assay(ELISA). Results:The results of mechanical pain sensitivity showed that there was no significant difference in the mechanical pain threshold in the right facial sensory area of the experimental rats in each group before surgery(all P>0.05).From the 3rd day after operation,the mechanical pain threshold of rats in the TN group was significantly lower than that in the sham group(all P<0.01),and the mechanical pain threshold of rats in the TN+80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 CBZ mg/kg group was higher than that in the TN group(all P<0.05).The BDNF and TrkB mRNA and protein expressions in TGs of rats in the TN group were higher than those in the sham group(all P<0.05),and those in the TN+80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 mg/kg CBZ group were lower than the TN group(all P<0.05).The p-ERK levels in TG of rats in the TN+80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 mg/kg CBZ group were significantly decreased compared with the TN group(all P<0.05).The BDNF and neuron-specific nuclear protein(NeuN)were mainly co-expressed in neuron of TGs in the TN group and they were significantly higher than those in the sham group(all P<0.05).The co-labeled expressions of BDNF and NeuN in TGs of the TN+ 80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 mg/kg CBZ group were lower than those in the TN group(all P<0.05).The results of ELISA showed that the level of BDNF in the serum of the TN group was significantly higher than that in the sham group(P<0.05).The levels of BDNF in the TN+80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 mg/kg CBZ group were lower than those in the TN group(all P<0.05).Spearman correlation analysis showed that the BDNF level in serum was negatively correlated with mechanical pain threshold(r=-0.650,P<0.01). Conclusion:CBZ treatment can inhibit the expression of BDNF and TrkB in the TGs of TN rats,reduce the level of BDNF in serum of TN rats and the phosphorylation of ERK signaling pathway,so as to inhibit TN.The serum level of BDNF can be considered as an indicator for the diagnosis and prognosis of TN.

Objective To build the early predictive model for chronic kidney disease(CKD)in hypertension and diabetes patients in the community.Methods The CKD patients were recruited from 4 health care centers in 4 urban areas in Kunming.The control group was residents without hypertension and diabetes(n = 1267).The disease group was residents with hypertension and/or diabetes(n = 566).The questionnaire survey,physical examination,laboratory testing,and 5 SNPs gene types in the PVT1 gene.The risk factors,which were filtered with logistics regression,were used to build predictive models.Four machine learning algorithms were built:support vector machine(SVM),random forest(RF),Na?ve Bayes(NB),and artificial neural network(ANN)models.Results Thirteen indicators included in the final diagnostic model:age,disease type,ethnicity,blood urea nitrogen,creatinine,eGFR from MDRD,ACR,eGFR from EPI2009,PAM13 score,sleep quality survey,staying-up late,PVT1 SNP rs11993333 and rs2720659.The accuracy,specificity,Kappa value,AUC of ROC,and PRC of ANN are greater than those of the other 3 models.The sensitivity of RF is the highest among 4 types of machine learning.Conclusions The ANN predictive model has a good ability of efficiency and classification to predict CKD with hypertension and/or diabetes patients in the community.
