Objective:To evaluate the safety and effectiveness of incision and drainage with Holmium laser under flexible ureteroscope in the treatment of parapelvic cysts.Methods:The clinical data of 21 patients with parapelvic cysts in Beijing Friendship Hospital, Capital Medical University from January 2018 to December 2022 were retrospectively analyzed, including 10 males and 11 females. The average age was (62.86±5.38) years, and median age was 63.0 years, aged from 36-72 years. The maximum diameter of the cyst was 33-71 mm, with an average of (53.46±9.68) mm. There were 15 cases with homolateral hydronephrosis and 6 cases with homolateral renal calculus. The patients included in the study were treated with incision and drainage with Holmium laser under flexible ureteroscope. The double J ureteral catheter was removed and the urinary system ultrasound was repeated one month after surgery. CT on bilateral kidney was repeated every 6 months until 12 months after surgery. Subsequently, ultrasound on bilateral kidney was reviewed regularly every year. Prognostic indexes sunch as operation time, postoperative hospital stay, postoperative time of getting out of bed, intraoperative blood loss, recurrence and shrinkage of renal cysts were recorded.Results:Of the 21 patients who underwent incision and drainage with Holmium laser under flexible ureteroscope, 9 cases (42.9%) underwent the one-stage operation and 12 cases (57.1%) underwent the two-stage operation. The mean operative time was (41.57±10.86) min, the mean postoperative hospitalization time was (2.90±1.06) d, the mean time of getting out of bed was (0.53±0.30) d, and the mean intraoperative blood loss was (6.52±2.15) mL. No significant recurrence of cysts was observed in all patients after 6-60 months of follow-up, and the cysts disappeared completely or shrank significantly.Conclusion:Incision and drainage with Holmium laser under flexible ureteroscope is safe and reliable in patients with parapelvic cysts, with short operation time, minor blood loss, rapid postoperative recovery and low recurrence rate, which is one of the ideal treatment options for parapelvic cysts.

Objective To investigate the effects of Echinococcus multilocularis on the phenotypic transformations of glucose metabolism, polarization types and inflammatory responses in macrophages, so as to provide insights into elucidation of echinococcosis pathogenesis. Methods Bone marrow cells were isolated from C57BL/6J mice at ages of 6 to 8 weeks, and induced into bone marrow-derived macrophages (BMDMs) with mouse macrophage colony-stimulating factor (M-CSF), which served as controls (BMDMs-M0). BMDMs-M0 induced M2 macrophages by interleukin-4 for 24 hours served as the IL-4 induction group, and BMDMs-M0 co-cultured with 2.4 ng/mL E. multilocularis cystic fluid (CF) served as the BMDM-CF co-culture group, while BMDMs-M0 co-cultured with E. multilocularis protoscolex (PSC) at a ratio of 500:1 served as the BMDM-PSC co-culture group. The types of polarization of BMDMs co-cultured with E. multilocularis CF and PSC were analyzed using flow cytometry, and the expression of macrophage markers, inflammatory factors, and glucose metabolism-related enzymes was quantified using fluorescent quantitative real-time PCR (qPCR) and Western blotting assays. Results There were significant differences among the four groups in terms of Arginase-1 (Arg1) (F = 1 457.00, P < 0.000 1), macrophages-derived C-C motif chemokine 22 (Ccl22) (F = 22 203.00, P < 0.000 1), resistin-like α (Retnla) (F = 151.90, P < 0.000 1), inducible nitric oxide synthase (iNOS) (F = 107.80, P < 0.001), hexokinase (HK) (F = 9 389.00, P < 0.000 1), pyruvate kinase (PK) (F = 641.40, P < 0.001), phosphofructokinase 1 (PFK1) (F = 43.97, P < 0.01), glucokinase (GK) (F = 432.50, P < 0.000 1), pyruvate dehydrogenase kinases1 (PDK1) (F = 737.30, P < 0.000 1), lactic dehydrogenase (LDH) (F = 3 632.00, P < 0.000 1), glucose transporter 1 (GLUT1) (F = 532.40, P < 0.000 1), glyceraldehyde-3-phosphate dehydrogenase (GAPDH) (F = 460.00, P < 0.000 1), citrate synthase (CS) (F = 5 642.00, P < 0.01), glycogen synthase1 (GYS1) (F = 273.30, P < 0.000 1), IL-6 (F = 1 823.00, P < 0.000 1), IL-10 (F = 291.70, P < 0.000 1), IL-1β (F = 986.60, P < 0.000 1), and tumor necrosis factor (TNF)-α (F = 334.80, P < 0.000 1) and transforming growth factor (TGF)-β mRNA expression (F = 163.30, P < 0.001). The proportion of M2 macrophages was significantly higher than that of M1 macrophages in the BMDM-PSC co-culture group [(22.87% ±1.48%) vs. (1.70% ±0.17%); t = 24.61, P < 0.001], and the proportion of M2 macrophages was significantly higher than that of M1 macrophages in the BMDM-CF co-culture group [(20.07% ±0.64%) vs. (1.93% ±0.25%); t = 45.73, P < 0.001]. The mRNA expression of M2 macrophages markers Arg1, Ccl22 and Retnla was significantly higher in the BMDM-CF and BMDM-PSC co-culture groups than in the control group (all P values < 0.01), and no significant difference was seen in the mRNA expression of the M1 macrophage marker iNOS among the three groups (P > 0.05), while qPCR assay quantified higher mRNA expression of key glycolytic enzymes HK, PK and PFK, as well as inflammatory factors IL-10, IL-1β, TNF-α and TGF-β in the BMDM-CF and BMDM-PSC co-culture groups than in the control group (all P values < 0.01). Western blotting assay determined higher HK, PK and PFK protein expression in the BMDM-PSC co-culture group than in the control group (all P values < 0.05), and qPCR quantified higher GLUT1, GAPDH and IL-6 mRNA expression in the BMDM-CF co-culture group than in the control group (all P values < 0.05), while higher HK, PK and PFK protein and mRNA expression (all P values < 0.01), as well as lower IL-6 and TNF-α and higher TGF-β mRNA expression (both P values < 0.05) was detected in the IL-4 induction group than in the control group. Glycolytic stress test showed no significant difference in the extracellular acidification rate (ECAR) of mouse BMDM among the control group, IL-4 induction group and BMDM-PSC co-culture group (F = 124.4, P < 0.05), and a higher ECAR was seen in the BMDM-PSC co-culture group and a lower ECAR was found in the IL-4 induction group than in the control group (both P values < 0.05). Conclusions Treatment of E. multilocularis CF or PSC mainly causes polarization of BMDM into M2 macrophages, and phenotypic transformation of glucose metabolism into high-energy and high-glycolytic metabolism, and affects inflammatory responses in BMDM.

Objective:To compare the specific mechanism and effects between christina loosestrife and snowbellleaf tickclover herb on kidney calcium oxalate calculi in rats.Methods:A total of 54 SPF grade SD male rats were fed adaptically for 1 week to 180-200 g, the models of rats with kidney calcium oxalate calculi were established by intragastric administration with glycol, and divided into nine groups according to random number table method and controlled, which were healthy control group (group A), positive control group (model group, group B), low, medium and high doses of christina loosestrife groups (C1, C2, C3, 3 groups), low, medium and high doses of snowbellleaf tickclover herb groups (D1, D2, D3, 3 groups), therapeutic control group (potassium sodium hydrogen citrate group, group E), 6 rats in each group. After 4 weeks, samples were collected to determine the urine and serum biochemical indexes of each group, and Von Kossa staining was used to detect kidney calcium oxalate crystals. Calcium oxalate crystal deposition in kidney tissues of rats was observed under polarization microscope, and the difference of efficacy between the two drug effects was determined by the percentage of positive area in photos and the urine and serum biochemical indexes. The measurement data were expressed as mean ± standard deviation ( ± s), one-way analysis of variance was used for comparison between groups, and SNK- q test was used for comparison between two groups. Kruskal-Wallis test was used to compare crystal formation between groups. Results:Compared with the positive control group and christina loosestrife groups, high dose of snowbellleaf tickclover herb could significantly reduce serum creatinine level ( P<0.01), the mean serum creatinine of rats with christina loosestrife was (86.70±11.49) μmol/L, that of rats with snowbellleaf tickclover herb was (70.72±9.08) μmol/L, the difference was statistically significant ( P<0.01). High dose of christina loosestrife and snowbellleaf tickclover herb could significantly increase urinary magnesium and decrease serum urea levels, and there was no statistical significance between them ( P>0.05). Compared with the positive control group, high dose of christina loosestrife ( P<0.000 1) and snowbellleaf tickclover herb ( P<0.000 1) could both inhibit the formation of calcium oxalate crystals and protect the kidney of rats, and there was no statistical significance between the two effects ( P>0.05). The levels of urine pH value could not be increased, while the levels of urinary calcium urinary oxalic acid and 24 h urine volume, serum calcium, serum phosphorus, serum magnesium, blood uric acid and content of kidney oxalate could not be decreased significantly after using these two drugs. Conclusion:Snowbellleaf tickclover herb is better than christina loosestrife in preventing recurrence of kidney calcium oxalate calculi and protecting renal function.
