Objective: To explore the effects of Cldn14 gene knockout on renal metabolism and stone formation in rats，so as to provide reference for research in the field of urinary calium metabolism and stone formation. Methods: Cldn14 gene knockout homozygous rats and wild-type rats of the same age were randomly divided into 4 groups：wild-type control (WC) group，wild-type ethylene glycol (WE) group，gene knockout control (KC) group and gene knockout ethylene glycol (KE) group，with 10 rats in each group.The WE and KE groups were induced with ethylene glycol + ammonium chloride to form kidney stones，while the WC and KC groups received normal saline gavage.After 4 weeks of standard maintenance feeding，the urine samples were collected to detect the venous blood.The kidneys were collected for HE，Pizzolatto's staining and transmission electron microscopy.The protein in renal tissues was extracted to detect the expressions of Claudin16 and Claudin19. Results: Crystal deposition was observed in the renal tubular lumen of the WE and the KE groups，and more crystals were detected in the KE group.The WE group had a large number of intracytoplasmic black crystalline inclusions observed in renal tubular epithelial cells under transmission electron microscope，followed by the KE and KC groups.Compared with WC and WE groups，KC and KE groups had significantly decreased serum calcium and magnesium levels but significantly increased urinary calcium level.In addition，the urinary calcium level was higher in the WE group than in the WC group and higher in the KE group than in the KC group.The KE group had lower level of Claudin16，but there was no significant difference in the level of Claudin19 among the 4 groups(P>0.05). Conclusion: Knockout of Cldn14 gene alone cannot effectively reduce urinary calcium excretion or reduce the risk of stone formation in rats，which may be related to the decrease of Claudin16 level.

Objective To evaluate the therapeutic efficacy for surgical treatments among patients with hepatic cystic echinococcosis in Gansu Province from 2006 to 2023, so as to provide insights into optimization of the diagnosis and treatment strategies against hepatic cystic echinococcosis. Methods The demographic and clinical data of all echinococcosis cases included in central government fiscal transfer payment program for echinococcosis control and undergoing surgical treatments in Gansu Province from 2006 to 2023 were captured. Hepatic cystic echinococcosis patients with complete medical records and follow-up data were included in the study, and patients’ characteristics, including hospital where patients received diagnosis and treatment, methods of case identification, year of surgery, classification of lesions, number of lesions, size of lesions, course of disease, surgical methods, and post-surgical follow-up data. The cure and recurrence of hepatic cystic echinococcosis were evaluated according to the Guidelines for Management of Echinococcosis Patients in the Central Government Fiscal Transfer Payment Program, and the cure and recurrent rates were calculated. Results Data were collected from 1 686 surgical patients with hepatic cystic echinococcosis. According to the inclusion and exclusion criteria, 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments were included during the period from 2006 to 2022, including 1 166 cured patients (95.42%) and 88 patients with postsurgical recurrence (7.20%), and the cure rate of surgical treatments appeared a tendency towards a rise among patients with hepatic cystic echinococcosis from 2008 to 2022 (χ²_trend = 19.39, P < 0.05). The cure rates of hepatic cystic echinococcosis were 100% (177/177), 94.81% (128/135) and 94.62% (861/910) among patients detected through regular physical examinations, screened by the central government fiscal transfer payment program for echinococcosis control, and those who passively sought healthcare services, respectively (χ² = 9.95, P < 0.05). The cure rates of hepatic cystic echinococcosis were 95.96% (1 046/1 090) among patients with a disease course of 2 years and less and 90.90% (120/132) among patients with a disease course of over 2 years (χ² = 6.87, P < 0.05), and there were significant differences in the cure rates among patients with hepatic cystic echinococcosis in terms of number of lesions (χ² = 24.44, P < 0.05) and surgical methods (P < 0.05). The cure rate of hepatic cystic echinococcosis patients was significantly higher following initiation of the central government fiscal transfer payment program for echinococcosis control (96.06%, 1 096/1 141) than before the program (86.42%, 70/81) (χ² = 16.06, P < 0.05), and the cure rate of hepatic cystic echinococcosis patients was significantly higher in designated hospitals (96.48%, 741/768) than in non-designated hospitals (93.37%, 366/392) (χ² = 5.78, P < 0.05). The median follow-up period was 4 (interquartile range, 7) years among 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments. The recurrent rate of hepatic cystic echinococcosis appeared a tendency towards a decline from 2008 to 2022 (χ²_trend = 36.86, P < 0.05), with a reduction from 23.08% (9/39) in 2008 to 1.85% (1/54) in 2021, and the post-surgical recurrence rate of hepatic cystic echinococcosis was lower following initiation of the central government fiscal transfer payment program for echinococcosis control (5.87%, 67 / 1 141) than before the program (25.93%, 21/81) (χ² = 45.51, P < 0.05). In addition, the post-surgical recurrence rate of hepatic cystic echinococcosis was higher in non-designated hospitals (10.46%, 41/392) than in designated hospitals (5.60%, 43/768) (χ² = 9.12, P < 0.05), and there was a significant difference in the post-surgical recurrence rate among patients with hepatic cystic echinococcosis in terms of surgical methods (P < 0.05), with the highest recurrence rate (11.54%) seen among patients undergoing percutaneous fine-needle aspiration of cyst fluids-based surgical procedures (P < 0.05). Conclusion Since the initiation of the central government fiscal transfer payment program for echinococcosis control in Gansu Province in 2006, an increase in the surgical cure rate and a reduction in the recurrence of hepatic cystic echinococcosis had been found among patients with hepatic cystic echinococcosis, indicating a high overall therapeutic efficacy.

Objective:To discuss the effects of kallikrein 5(KLK5)overexpression on the proliferation,invasion and cisplatin(DDP)sensitivity of cervical cancer cells,and to clarify its mechanism.Methods:Western blotting method was used to verify the stable transfection and overexpression of KLK5 in the cervical cancer cell(ME180-OE-KLK5).The cervical cancer ME180-NC-KLK5 and ME180-OE-KLK5 cells in logarithmic growth phase were subcutaneously inoculated into the nude mice to establish the subcutaneous xenograft models.After successful modeling,the mice were randomly divided into normal saline control group(NC-KLK5+0.9％NaCl group),DDP treatment group(NC-KLK5+DDP group),KLK5 overexpression group(OE-KLK5+0.9％NaCl group)and KLK5 overexpression combined with DDP group(OE-KLK5+DDP group),with 5 mice in each group.The nude mice in NC-KLK5+DDP group and OE-KLK5+DDP group were given intraperitoneal injection of DDP at a dose of 5 mng·kg-1;the nude mice in NC-KLK5+0.9％NaCl group and OE-KLK5+0.9％NaCl group were given intraperitoneal injection of normal saline at a dose of 0.01 mL·g-1.The body weights of nude mice were measured every 2 d,and the long diameter and short diameter of the tumors were recorded to calculate the tumor volume and plot the tumor growth curve.At 24 h after the last administration on day 14,the nude mice were sacrificed,and the tumors were dissected and weighed.HE staining method was used to observe the pathomorphology of tumor tissue in the nude mice in various groups;immunohistochemistry staining method was used to observe the expression levels of KLK5,Ki67 and matrix metalloproteinase-9(MMP-9)proteins in the tumor tissues of the nude mice in various groups.Results:Compared with ME180-NC-KLK5 cells,the expression level of KLK5 protein in ME180-OE-KLK5 cells was increased(P＜0.05).In the first week after subcutaneous xenograft inoculation,the nude mice in various groups showed good feeding and activity status,and their body weights gradually increased.The drug administration phase started from the second week.During the drug treatment period,the feeding and activity status as well as body weight of the nude mice in NC-KLK5+0.9％NaCl group showed no significant changes compared with the first week;compared with NC-KLK5+0.9％NaCl group,the nude mice in NC-KLK5+DDP group began to show loss of appetite,no increase in body weight,and decreased activity.During the drug treatment period in the third week,the feeding and activity status of the nude mice in NC-KLK5+0.9％NaCl group showed no significant changes compared with the second week,while they began to show no increase in body weight;compared with NC-KLK5+0.9％NaCl group,the feeding and activity status of the nude mice in NC-KLK5+DDP group were significantly weakened,and their body weights decreased.Compared with NC-KLK5+0.9％NaCl group,the volume of xenograft tumor in NC-KLK5+DDP group was decreased(P＜0.01);compared with NC-KLK5+DDP group,the volume of xenograft tumor OE-KLK5+DDP group was significantly increased(P＜0.001);compared with NC-KLK5+0.9％NaCl group,the volume of xenograft tumor of the nude mice in OE-KLK5+0.9％NaCl group was increased(P＜0.001);compared with OE-KLK5+0.9％NaCl group,the volume of xenograft tumors in the nude mice in OE-KLK5+DDP group showed no statistically significant difference(P＞0.05).Compared with NC-KLK5+0.9％NaCl group,the weight of xenograft tumor of the nude mice in NC-KLK5+DDP group was decreased(P＜0.05);compared with NC-KLK5+DDP group,the weight of xenograft tumors of the nude mice in OE-KLK5+DDP group was significantly increased(P＜0.001);compared with NC-KLK5+0.9％NaCl group,the weight of xenograft tumor of the nude mice in OE-KLK5+0.9％NaCl group was increased(P＜0.001);compared with OE-KLK5+0.9％NaCl group,the weight of xenograft tumors of the nude mice in OE-KLK5+DDP group showed no statistically significant difference(P＞0.05).Compared with NC-KLK5+0.9％NaCl group,the xenograft tumor cells of the nude mice in OE-KLK5+0.9％NaCl group showed greater nuclear heterogeneity;the xenograft tumor cells of the nude mice in OE-KLK5+DDP group and NC-KLK5+DDP group showed cytomorphological changes,manifested as nuclear pyknosis and fragmentation,reduced cell volume,and the appearance of necrosis and apoptosis.Compared with NC-KLK5+DDP group,the degree of necrosis in xenograft tumor of the nude mice in OE-KLK5+DDP group was more pronounced.Compared with NC-KLK5+0.9％NaCl group,the expression levels of KLK5,Ki67 and MMP-9 proteins in xenograft tumor tissue of the nude mice in NC-KLK5+DDP group were decreased(P＜0.05);compared with NC-KLK5+DDP group,the expression levels of KLK5,Ki67,and MMP-9 proteins in xenograft tumor tissue of the nude mice in OE-KLK5+DDP group were increased(P＜0.001);compared with NC-KLK5+0.9％NaCl group,the expression levels of KLK5,Ki67 and MMP-9 proteins in xenograft tumor tissue of the nude mice in OE-KLK5+0.9％NaCl group were increased(P＜0.001);compared with OE-KLK5+0.9％NaCl group,the expression levels of KLK5,Ki67 and MMP-9 in xenograft tumor tissue of the nude mice in OE-KLK5+DDP group showed no statistically significant differences(P＞0.05).Conclusion:KLK5 overexpression can promote the growth of subcutaneous xenograft tumors of cervical cancer ME 180 cells treated with DDP,up-regulate the expressions of Ki67 and MMP-9 in the xenograft tumor tissue,and reduce the sensitivity of the xenograft tumor to DDP.
