Objective:To discuss the effect of acupuncture on the differentiation and apoptosis of quadriceps muscle satellite cells in model rats with knee osteoarthritis(KOA),and to clarify its related mechanism.Methods:A total of 40 SPF-grade rats were selected and randomly divided into control group,model group,celecoxib group,and acupuncture group,with 10 rats in each group.The rats in control group only underwent joint cavity incision followed by suturing,while the rats in model group,celecoxib group,and acupuncture group were used to replicate the KOA models.The maximum circumference of the femoral segment of the affected limb,rat body mass,and quadriceps wet weight of the rats in various groups were measured;the quadriceps wet weight maintenance rate and quadriceps wet weight/body mass ratio of the rats in various groups were calculated.HE staining was used to observe the pathomorphology of articular cartilage and quadriceps muscle tissue of the rats in various groups;terminal deoxynucleotidyl transferase(TdT)-mediated dUTP nick end labeling(TUNEL)method was used to detect the apoptosis indexes in articular cartilage and quadriceps muscle tissue of the rats in various groups;immunofluorescence method was used to detect the protein expression levels of interleukin-6(IL-6),Janus kinase(JAK),and signal transducer and activator of transcription 3(STAT3)in quadriceps muscle tissue of the rats in various groups;Western blotting method was used to detect the expression levels of IL-6/JAK/STAT3 signaling pathway proteins,and muscle satellite cells,and apoptosis-related proteins in quadriceps muscle tissue of the rats in various groups.Results:Compared with control group,the affected hind limb circumference,quadriceps wet weight,wet weight maintenance rate,and wet weight/body mass ratio of the rats in model group were significantly decreased(P<0.05);compared with model group,the affected hind limb circumference,quadriceps wet weight,wet weight maintenance rate,and wet weight/body mass ratio of the rats in celecoxib group and acupuncture group were significantly increased(P<0.05);compared with celecoxib group,the affected hind limb circumference,quadriceps wet weight,wet weight maintenance rate,and wet weight/body mass ratio of the rats in acupuncture group were significantly increased(P<0.05).The HE staining results showed that the knee articular cartilage of the rats in control group remained intact,chondrocytes were aggregated and horizontally arranged with smooth edges,and quadriceps muscle cells were long cylindrical,orderly arranged,and regular in shape;in model group,the knee articular cartilage was thinner with rough edges,reduced number of cartilage layers,and disordered arrangement,and the quadriceps muscle fibers were disorganized,with some muscle fiber dissolution and muscle cell membrane damage,accompanied by muscle fiber fragments and a large amount of inflammatory exudate;in celecoxib group,the morphology of knee articular cartilage was generally normal,occasionally with irregular cartilage arrangement and reduced thickness,sporadically visible necrotic chondrocytes,quadriceps muscle fibers and sarcolemma were relatively intact,new muscle fibers appeared,some muscle fiber edges were blurred,accompanied by a small amount of cell debris and mild inflammatory infiltration;in acupuncture group,the knee articular cartilage structure remained intact with smooth edges,occasionally rough edges,and chondrocytes were aggregated and orderly arranged.The TUNEL assay results showed that compared with control group,the apoptosis indexes in articular cartilage and quadriceps muscle tissue of the rats in model group were significantly increased(P<0.05);compared with model group,the apoptosis indexes in articular cartilage and quadriceps muscle tissue of the rats in celecoxib group and acupuncture group were significantly decreased(P<0.05);compared with celecoxib group,the apoptosis index in articular cartilage and quadriceps muscle tissue of the rats in acupuncture group were significantly decreased(P<0.05).The immunofluorescence assay results showed that compared with control group,the expression levels of IL-6,JAK,and STAT3 proteins in quadriceps muscle tissue of the rats in model group were significantly decreased(P<0.05);compared with model group,the expression levels of IL-6,JAK,and STAT3 proteins in quadriceps muscle tissue of the rats in celecoxib group and acupuncture group were significantly increased(P<0.05);compared with celecoxib group,the expression levels of IL-6,JAK,and STAT3 proteins in quadriceps muscle tissue of the rats in acupuncture group were significantly increased(P<0.05).The Western blotting results showed that compared with control group,the expression levels of IL-6,JAK,STAT3,paired box transcription factor 7(Pax7),Desmin,Myosin,and Myogenin proteins in quadriceps muscle tissue of the rats in model group were significantly decreased(P<0.05);compared with model group,the expression levels of IL-6,JAK,STAT3,Pax7,Desmin,Myosin,and Myogenin proteins in quadriceps muscle tissue of the rats in celecoxib group and acupuncture group were significantly increased(P<0.05);compared with celecoxib group,the expression levels of IL-6,JAK,STAT3,Pax7,Desmin,Myosin,and Myogenin proteins in quadriceps muscle tissue of the rats in acupuncture group were significantly increased(P<0.05).Compared with control group,the expression levels of B-cell lymphoma 2(Bcl-2),B-cell lymphoma-xl(Bcl-xl),and myeloid cell leukemia 1(MCL1)proteins in quadriceps muscle tissue in model group were significantly decreased(P<0.05),and the expression levels of Bcl-2-associated X protein(Bax)and cysteinyl aspartate specific proteinase-3(Caspase-3)proteins were significantly increased(P<0.05);compared with model group,the expression levels of Bcl-2,Bcl-xl,and MCL1 proteins in quadriceps muscle tissue of the rats in celecoxib group and acupuncture group were significantly increased(P<0.05),and the expression levels of Bax and Caspase-3 proteins were significantly decreased(P<0.05);compared with celecoxib group,the expression levels of Bcl-2,Bcl-xl,and MCL1 proteins in quadriceps muscle tissue of the rats in acupuncture group were significantly increased(P<0.05),and the expression levels of Bax and Caspase-3 proteins were significantly decreased(P<0.05).Conclusion:Acupuncture can promote the differentiation of quadriceps muscle satellite cells and inhibit muscle cell apoptosis in the model rats with KOA,and the mechanism may be related to the up-regulation of expressions of IL-6,JAK,and STAT3 proteins in the quadriceps muscle tissue.

Mitochondria are the main site of energy metabolism in cardiomyocytes, and at the same time mediate apoptosis and immune response, so mitochondrial dysfunction is closely related to the development of heart failure. Combined with the pathogenesis of mitochondrial dysfunction and heart failure, it is proposed that the mitochondrial function is similar to "sweat pore - collaterals - zang and fu organs", according to which the treatment of heart failure is based on the theory of "sweat pore - collaterals - zang and fu organs". It is believed that the core mechanism of heart failure is qi deficiency, and qi deficiency leads to the weakness of the sweat pore opening and closing, or even the sweat pore closure, then resulting in qi deficiency and blood stasis, collaterals stagnation fail to flourish, and qi, blood, and body fluids can not infiltrate and nourish zang-fu organs, so that the heart fail to be nourished, and the disease will develop. The treatment should be based on the method of boosting qi and opening sweat pore, using acridity to unblock the collaterals, and invigorating blood and draining water, with medicinal of boosting qi, invigorating blood, and draining water as treatment.

Purpose:
This study aims to explore whether neoadjuvant chemotherapy with immunotherapy (NACI) leads to different tumor shrinkage patterns, based on magnetic resonance imaging (MRI), compared to neoadjuvant chemotherapy (NAC) alone in patients with triple-negative breast cancer (TNBC). Additionally, the study investigates the relationship between tumor shrinkage patterns and treatment efficacy was investigated.
Methods:
This retrospective study included patients with TNBC patients receiving NAC or NACI from January 2019 until July 2021 at our center. Pre- and post-treatment MRI results were obtained for each patient, and tumor shrinkage patterns were classified into three categories as follows: 1) concentric shrinkage (CS); 2) diffuse decrease; and 3) no change.Tumor shrinkage patterns were compared between the NAC and NACI groups, and the relevance of the patterns to treatment efficacy was assessed.
Results:
Of the 99 patients, 65 received NAC and 34 received NACI. The CS pattern was observed in 53% and 20% of patients in the NAC and NACI groups, respectively. Diffuse decrease pattern was observed in 36% and 68% of patients in the NAC and NACI groups. The association between the treatment regimens (NAC and NACI) and tumor shrinkage patterns was statistically significant (p = 0.004). The postoperative pathological complete response (pCR) rate was 45% and 82% in the NAC and NACI groups (p < 0.001), respectively. In the NACI group, 17% of patients with the CS pattern and 56% of those with the diffuse decrease pattern achieved pCR (p = 0.903). All tumor shrinkage patterns were associated with achieved a high pCR rate in the NACI group.
Conclusion
Our study demonstrates that the diffuse decrease pattern of tumor shrinkage is more common following NACI than that following NAC. Furthermore, our findings suggest that all tumor shrinkage patterns are associated with a high pCR rate in patients with TNBC treated with NACI.

Objective:To investigate the changes of T lymphocyte subsets in peripheral blood of patients with diffuse large B-cell lymphoma (DLBCL) and its clinical significance.Methods:The clinical data of 99 DLBCL patients admitted to the First Affiliated Hospital of Xiamen University from January 2022 to January 2023 were retrospectively analyzed. T lymphocyte subsets in peripheral blood before and after treatment were detected by using flow cytometry. According to the disease status at the time of blood collection and detection, the patients were divided into the newly-diagnosed DLBCL group (28 cases), and the newly-treated remission DLBCL group (71 cases); and 40 healthy volunteers undergoing the physical examination during the same period were selected as the healthy control group. The proportion and absolute count differences of T lymphocytes and the related subsets in 3 groups were compared. Besides, the correlation among T lymphocyte subsets, the correlation of each subset with international prognostic index (IPI) score and treatment response in newly-diagnosed DLBCL patients were further analyzed.Results:The proportion of CD3 + T cells in newly-diagnosed DLBCL group was decreased compared with that in the healthy control group [(58±14)% vs. (67±7)%, P < 0.05]. The absolute count of CD3 + T cells in both newly-diagnosed group and the newly-treated remission group was reduced compared with that in the healthy control group [(875±483) /μl and (808±553) /μl vs. (1 374±279) /μl, P < 0.001]. The absolute count of CD4 + and CD8 + T cells in newly-diagnosed group was decreased compared with that in the healthy control group [(478±313) /μl vs. (695±154) /μl, (316±181) /μl vs. (525±193) /μl, all P < 0.001]. Both the proportion and absolute count of CD4 + T cells in the newly-treated remission DLBCL group were decreased compared with those in the newly-diagnosed DLBCL group and the healthy control group [(40±14)% vs. (53±14)% and (51±9)%, (313±247) /μl vs. (478±313) /μl and (695±154) /μl, all P < 0.05]. The porportion of CD8 + T cells was increased compared with that in the other two groups [(51±15)% vs. (37±12)% and (38±9)%, all P < 0.001]. Compared with the healthy control group, the effect/memory subsets proportion of regulatory T cell (Treg) and conventional T cell (Tcon) were increased in both newly-diagnosed DLBCL group and the newly-treated remission DLBCL group [(79±16)% and (84±12)% vs. (71±11)%,(72±16)% and (76±14)% vs. (62±13)%, all P < 0.05], and the proportion of CD127 + memory Tcon and CD8 + T cell subsets was reduced [(73±14)% and (66±20)% vs. (85±8)%,(39±15)% and (25±21)% vs. (62±16)%, all P < 0.05]. In newly-diagnosed DLBCL group, the absolute counts of CD3 + T and CD4 + T cells were negatively correlated with the proportion of effector Treg ( r = -0.379, P = 0.049; r = -0.384, P = 0.040, respectively). IPI score of DLBCL patients was correlated with the proportion of CD8 + T cells ( Eta2 = 0.15, P = 0.038). The proportion of CD127 + memory Tcon in patients with non-complete remission was increased compared with that in patients with complete remission after treatment ( P = 0.020). Conclusions:The proportion and absolute count of T lymphocyte cells in peripheral blood of newly-diagnosed DLBCL patients is decreased, and the differentiation state of T lymphocyte cells shows change trend, which is related to the clinical characteristics and treatment response of DLBCL patients. Even if DLBCL patients have achieved treatment remission, T lymphocyte cells are not completely return to the normal.

OBJECTIVE To develop a whole-process intelligent model of pharmaceutical care for peritoneal dialysis (PD) patients, and to provide a reference for clinical pharmacists to provide standardized PD pharmaceutical care. METHODS The pharmaceutical care mode of PD patients at home and abroad was investigated and analyzed. Based on the actual situation of the First Affiliated Hospital of Soochow University (hereinafter referred to as “our hospital”), with “home→PD center outpatient→ inpatient department” as the main node, the recycling process of medication reconciliation was optimized. The whole-process intelligent pharmaceutical care model of PD was illustrated by improving the Chinese version of the drug-related problems (DRPs) classification tool, developing the corresponding pharmaceutical care process, and presenting specific cases. RESULTS Based on the medication therapy management (MTM) platform, our hospital had built a closed-loop PD whole-process intelligent pharmaceutical care model of “in-hospital pharmaceutical care (building document)-PD outpatient MTM-home pharmaceutical care (online App management)”. A “double cycle” workflow of “admission→discharge→outpatient” medication reconciliation cycle and “discovery-analysis-intervention-follow-up-record-evaluation” DRPs cycle was formed. CONCLUSIONS The establishment of the whole-process intelligent pharmaceutical care model for PD in our hospital provides experience for standardizing pharmaceutical care for PD patients, and can reduce DRPs.

Background::High-dose dual therapy (HDDT) with proton pump inhibitors (PPIs) and amoxicillin has attracted widespread attention due to its favorable efficacy in eradicating Helicobacter pylori ( H. pylori). This study aimed to compare the efficacy and safety of high-dose PPI–amoxicillin dual therapy and bismuth-containing quadruple therapy for H. pylori rescue treatment. Methods::This was a prospective, randomized, multicenter, non-inferiority trial. Patients recruited from eight centers who had failed previous treatment were randomly (1:1) allocated to two eradication groups: HDDT (esomeprazole 40 mg and amoxicillin 1000 mg three times daily; the HDDT group) and bismuth-containing quadruple therapy (esomeprazole 40 mg, bismuth potassium citrate 220 mg, and furazolidone 100 mg twice daily, combined with tetracycline 500 mg three times daily; the tetracycline, furazolidone, esomeprazole, and bismuth [TFEB] group) for 14 days. The primary endpoint was the H. pylori eradication rate. The secondary endpoints were adverse effects, symptom improvement rates, and patient compliance. Results::A total of 658 patients who met the criteria were enrolled in this study. The HDDT group achieved eradication rates of 75.4% (248/329), 81.0% (248/306), and 81.3% (248/305) asdetermined by the intention-to-treat (ITT), modified intention-to-treat (MITT), and per-protocol (PP) analyses, respectively. The eradication rates were similar to those in the TFEB group: 78.1% (257/329), 84.2% (257/305), and 85.1% (257/302). The lower 95% confidence interval boundary (–9.19% in the ITT analysis, –9.21% in the MITT analysis, and –9.73% in the PP analysis) was greater than the predefined non-inferiority margin of –10%, establishing a non-inferiority of the HDDT group vs. the TFEB group. The incidence of adverse events in the HDDT group was significantly lower than that in the TFEB group (11.1% vs. 26.8%, P < 0.001). Symptom improvement rates and patients’ compliance were similar between the two groups. Conclusions::Fourteen-day HDDT is non-inferior to bismuth-containing quadruple therapy, with fewer adverse effects and good treatment compliance, suggesting HDDT as an alternative for H. pylori rescue treatment in the local region. Trial registration::Clinicaltrials.gov, NCT04678492.

Laparoscopic proximal gastrectomy (LPG) can be selected for the treatment of early upper gastric carcinoma, but gastroesophageal reflux after operation would seriously affect the quality of life of patients. Esophagogastric anastomosis with double flap technique is a digestive tract reconstruction method using the anastomosis between the esophagus and the anterior wall of the stomach. Compared with other digestive tract reconstruction methods, esophagogastric anastomosis with double flap technique can maintain the postoperative body mass of patients in good condition, improve the nutritional status and the long-term quality of life of patients. Esophagogastric anasto-mosis with double flap technique has good anti reflux effects and retain the possibility of endoscopic examination and treatment. By reviewing literatures at home and abroad, and combined with clinical experiences, the authors discuss current status and digestive tract reconstruction methods of LPG, and deeply investigate the application prospect of esophagogastric anastomosis with double flap technique.

Glycolytic metabolism enzymes have been implicated in the immunometabolism field through changes in metabolic status. PGK1 is a catalytic enzyme in the glycolytic pathway. Here, we set up a high-throughput screen platform to identify PGK1 inhibitors. DC-PGKI is an ATP-competitive inhibitor of PGK1 with an affinity of K d = 99.08 nmol/L. DC-PGKI stabilizes PGK1 in vitro and in vivo, and suppresses both glycolytic activity and the kinase function of PGK1. In addition, DC-PGKI unveils that PGK1 regulates production of IL-1β and IL-6 in LPS-stimulated macrophages. Mechanistically, inhibition of PGK1 with DC-PGKI results in NRF2 (nuclear factor-erythroid factor 2-related factor 2, NFE2L2) accumulation, then NRF2 translocates to the nucleus and binds to the proximity region of Il-1β and Il-6 genes, and inhibits LPS-induced expression of these genes. DC-PGKI ameliorates colitis in the dextran sulfate sodium (DSS)-induced colitis mouse model. These data support PGK1 as a regulator of macrophages and suggest potential utility of PGK1 inhibitors in the treatment of inflammatory bowel disease.
