Objective To investigate the influence of magnesium sulfate on C-reactive protein, white blood cells, neutrophils, gastrointestinal function and serum bilirubin levels in patients with acute cholecystitis.Methods 117 patients with acute cholecystitis were randomly divided into two groups (n=60) and control group (n=57).The control group received conventional treatment, and observation group received conventional treatment combined with magnesium sulfate.The leukocyte count and neutrophil percentage, serum total bilirubin and CRP levels, plasma vasoactive intestinal peptide ( VIP) and motilin ( MTL) levels, and disappearance time of fever, abdominal pain, gallbladder enlargement were analysed between two groups of patients.Results After treatment, the leukocyte count and neutrophil percentage of observation group were significantly lower than those before treatment (P<0.05), but there were no significantly differences in above indexes of control group; after treatment, leukocyte count and neutrophil percentage in observation group were significantly lower than those in control group (P<0.05).After treatment, serum CRP and total bilirubin levels in observation group was significantly lower than that before treatment (P<0.05), and CRP level in control group was significantly lower than that before treatment (P<0.05), while total bilirubin level in control group showed no significant change; after treatment, the above indexes in observation group were significantly lower than that in control group (P<0.05).After treatment, plasma VIP levels in both groups was significantly lower than that before treatment, respectively (P<0.05), MTL levels were significantly higher than that before treatment, respectively (P<0.05);after treatment, VIP level was lower, MTL level was higher in observation group than that in control group, respectively (P<0.05).The disappearance time of fever, abdominal pain, gallbladder enlargement in observation group were significantly shorter than that in control group, respectively ( P<0.05 ) .Conclusion The mechanism of magnesium sulfate in the treatment of acute cholecystitis may reduce leukocyte count and neutrophil percentage, serum CRP and total bilirubin, plasma VIP level and increase MTL level.

ObjectiveTo investigate the effect of pulsatilla saponin A (PSA) on proliferation and apoptosis of human Burkitt lymphoma (BL) cell line Raji cells and expression of related pathway proteins. MethodWith Raji cells as the research object, the cell proliferation was detected by cell counting kit-8 (CCK-8) method, and the half-maximal inhibitory concentration (IC50) values of 24 h, 48 h and 72 h were calculated to be 19.77, 18.31, 16.70 μmol·L-1, respectively. In subsequent related experiments, 0, 8, 16, 32 μmol·L-1 PSA were selected according to the IC50 value of Raji cells treated with PAS for 72 h. After 0, 8, 16, 32 μmol·L-1 PSA acted on Raji cells for 24, 48, 72 h, the optical density values of cell growth curve were detected by CCK-8 method. The zymogen activities of cysteine aspartate-specific protease (Caspase)-3, Caspase-8 and Caspase-9 in Raji cells treated with 0, 8, 16 and 32 μmol·L-1 PSA for 24 h were measured by Caspase-3, Caspase-8 and Caspase-9 colorimetric assay kit. The apoptosis rate and cell cycle of Raji cells treated with different concentrations of PSA after 24 h were detected by flow cytometry. The expression of B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), cleaved poly(ADP-ribose) polymerase (cleaved PARP), cleaved cysteinyl aspartate-specific protease-3 (cleaved Caspase-3) apoptosis related protein and Janus kinase 2 (JAK2), signal transducer and activator of transcription 3 (STAT3), phosphorylated-JAK2 (p-JAK2), and phosphorylated- STAT3 (p-STAT3) pathway proteins in Raji cells after 24 h of treatment with 0, 8, 16 and 32 μmol·L-1 PSA were tested by Western blot. ResultCompared with control group, decreased cell survival rate, inhibited cell proliferation, activated zymogens of Caspase-3, Caspase-8 and Caspase-9 (P<0.01), increased apoptosis (P<0.05, P<0.01), and enhanced cell cycle arrest in Gap phase 2 (G2) were observed in 8, 16 and 32 μmol·L-1 PSA groups(P<0.05, P<0.01). Compared with control group, cells treated with 8, 16 and 32 μmol·L-1 PSA had lower expression of Bcl-2, p-JAK2, p-STAT3 proteins (P<0.05, P<0.01), and higher expression of Bax, cleaved PARP and cleaved Caspase-3 protein (P<0.01), while no significant change was found in the expression of JAK2 and STAT3 proteins. ConclusionPSA could inhibit proliferation and induce apoptosis of Raji cells, and its potential mechanism might be related to the regulation of JAK2/STAT3 signaling pathway.

ObjectiveTo investigate the effect of Qiling Baitouweng Tang (QLBTWT) on proliferation and apoptosis, Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway and interleukin-10 (IL-10) in diffuse large B-cell lymphoma (DLBCL). MethodWith human DLBCL cells OCI-LY10 and U2932 as research objects, cell proliferation was detected by cell counting kit-8 (CCK-8) assay. After treatment with 0, 4.6, 9.3, 18.7, 37.5, 75, 150 mg·L-1 QLBTWT for 24 h, the half-inhibitory concentration (IC50) of OCL-LY10 and U2932 cells was calculated to be 9.33, 16.13 mg·L-1, respectively, based on which, 9.5, 19, 38 mg·L-1 QLBTWT were selected for subsequent experiments. After 0, 9.5, 19, 38 mg·L-1 QLBTWT treatment for 24 h, the zymogen activities of Caspase-3, Caspase-8 and Caspase-9 in OCI-LY10 and U2932 cells were detected using corresponding activity assay kits (colorimetric), and the IL-10 expression was detected by enzyme-linked immuno sorbent assay (ELISA). The apoptosis rate and cell cycle of OCI-LY10 and U2932 cells treated with different concentrations of QLBTWT for 24 h were detected by flow cytometry. The expressions of apoptosis-related proteins [B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), cleaved poly adenosine diphosphate ribose polymerase (cleaved PARP), cleaved Caspase-3], JAK2, STAT3, phospho-JAK2 (p-JAK2), phospho-STAT3 (p-STAT3) pathway proteins, and c-Myc protein in OCL-LY10 and U2932 cells after 24 h treatment with 0, 9.5, 19, 38 mg·L-1 QLBTWT were all tested by Western blot. ResultAfter QLBTWT treatment on OCI-LY10 and U2932 cells for 24 h, cell proliferation was inhibited in each QLBTWT group compared with that in the control group (P<0.05, P<0.01). The zymogens of Caspase-3, Caspase-8 and Caspase-9 were activated (P<0.01), and there was an increase in cell apoptosis (P<0.05, P<0.01) and cell cycle arrest at Gap phase1 (G1) phase in 9.5, 19 and 38 mg·L-1 QLBTWT group (P<0.05, P<0.01). After 9.5, 19 and 38 mg·L-1 QLBTWT treatment on OCI-LY10 and U2932 cells for 24 h, the expressions of Bcl-2, p-JAK2 and p-STAT3 proteins were decreased (P<0.01), and the expressions of Bax, cleaved PARP and cleaved Caspase-3 proteins were increased (P<0.01), but no significant change was observed in the expressions of JAK2 and STAT3 proteins. Compared with the conditions in the control group, the expressions of c-Myc, p-JAK2, and p-STAT3 proteins were down-regulated in 19 mg·L-1 QLBTWT group and 19 mg·L-1 QLBTWT+10 μg·L-1 IL-10 group (P<0.05, P<0.01), and up-regulated in 10 μg·L-1 IL-10 group (P<0.05, P<0.01), while there was no difference in JAK2/STAT3 proteins. ConclusionQLBTWT can inhibit proliferation and induce apoptosis of human DLBCL cells OCI-LY10 and U2932, and the potential mechanism may be related to the regulation of JAK2/STAT3 signaling pathway.

【Objective】 To share the technical key points and experience of transvesical robot-assisted radical prostatectomy (TvRARP). 【Methods】 The clinical data of 13 patients with prostate cancer (PCa) receiving TvRARP during Nov.2021 and May 2022 were collected. The operation time, estimated blood loss, blood transfusion rate, catheter removal time, postoperative length of hospital stay, immediate urinary continence rate, postoperative IIEF-5 score and perioperative complications were evaluated. 【Results】 The operation time was (142±39) min, estimated intraoperative blood loss was (76±40) mL, and no transfusion was needed. The median postoperative IIEF-5 score was 16 (12-22), hospital stay 3 (2-5)days, and catheter removal time 7(5-14)days. Of all 13 patients, 12(92.3%) achieved immediate urinary continence at the removal of catheter. There were no postoperative complications of Clavien Ⅲ and above. Clavien Ⅰ-Ⅱ complications were observed in 4 patients (30.8%). 【Conclusion】 TvRARP is feasible and safe for selected patients with clinically localized PCa, which can ensure promising postoperative urinary continence and preserve erectile functional.
