OBJECTIVE: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture. METHODS: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve. RESULTS: Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats. CONCLUSION Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

Objective To describe the changing trend and related factors of prevalence rates of healthcare-associa-ted infection(HAI)in a tertiary hospital in the past 10 years,and analyze the influencing factors for HAI.Methods A cross-sectional survey on HAI was conducted for 10 consecutive years from 2013 to 2022(one day was selected as the survey day each year),data were collected.The distribution and related factors of prevalence rates of HAI were analyzed by trend-x2 test and Pearson correlation coefficient.Multivariate logistic regression and multilayer percep-tron(MLP)models were constructed to analyze the independent effect and significance of factors.Results From 2013 to 2022,the prevalence rates of HAI ranged from 4.66％to 8.07％in this hospital,showing a linear upward trend.The proportions of ICU patients and utilization rate of central venous catheters within 2 days before the sur-vey showed linear upward trends,while the proportion of patients with urinary catheters within 2 days before the survey and proportion of patients undergoing surgery within 30 days before the survey decreased.The MLP model revealed that the top 3 important factors for HAI were length of hospital stay＞10 days,admission in ICU,and in-dwelling central venous catheters within 2 days before the survey.Multivariate logistic regression model indicated that length of hospital stay＞10 days,indwelling central venous catheters or urinary catheters within 2 days before the survey,surgery within 30 days before the survey,and admission in ICU were independent influencing factors for HAI.Conclusion The incidence of HAI in this hospital presents a linear increase in recent 10 years,the causes should be further analyzed and the direction of intervention should be determined through targeted surveillance.Adopting trend test statistical analysis method,logistic regression,MLP multi-factor model can further explore the data value of HAI prevalence survey.

BACKGROUND: It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011. METHODS: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided). RESULTS: The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107). CONCLUSIONS: The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly. TRIAL REGISTRATION NUMBER NCT03620565, https://register.clinicaltrials.gov.

Objective:In the study of urine metabolomics of rats,necessary antiseptic measures should be taken for collection of urine samples,the effect of several antiseptic measures on the endogenous metabolites in urine was studied. Method:The urine samples of rats were collected on ice,sodium azide was added,and both of them were used together to prevent corrosion.Differences of antiseptic measures were analyzed by nuclear magnetic resonance (NMR) metabolomics. Result:The results of NMR metabolomics showed that sodium azide+ice group and ice group had many overlaps,but they clearly separated with the control group and sodium azide group;sodium azide group and the control group had a small part overlap,but there was a tendency of separation.The antiseptic effect of sodium azide+ice group and ice group was similar;compared with control group,valine,betaine and hippuricacid in these two groups increased,but the alanine and 2-ketoglutaric acid decreased. Conclusion:In the study of rat urine metabolomics,low temperature antiseptic measures must be taken when urine samples are collected,and the addition of sodium azide can improve the antiseptic effect slightly under protective conditions.

OBJECTIVETo explore the therapeutic effect of Yishen Qufeng Shengshi Recipe (, YQSR) in patients with glomerular proteinuria METHODS: A total of 145 patients with glomerular proteinuria were selected and randomly assigned to the treatment group (108 cases) and the control group (37 cases) according to a random number table in a ratio of 3:1. All patients received conventional and symptomatic treatment. In addition, patients in the treatment and control groups were given YQSR (200 mL, twice per day, orally) and losartan (50 mg/d orally), respectively for 6 months. The 24-h urine protein quantity, blood urea nitrogen, and serum creatinine in the two groups were measured at multiple time points before and after treatment.

RESULTSAt the end of the study, 5 cases were lost to follow-up in the treatment group and 1 in the control group. Finally, the statistical data included 103 cases in the treatment group and 36 cases in the control group. The total effectiveness after 2, 4, and 6 months was 81.6% (84/103), 87.4% (90/103), and 92.2% (95/103), respectively, in the treatment group and 47.2% (17/36), 55.6% (20/36), and 61.1% (22/36), respectively, in the control group, with significant difference between the two groups (P<0.01 at all observation points). In the treatment group, the curative effect after 6 months was better than that after 2 months (P<0.05). The 24-h urine protein quantity was significantly lower in the treatment group at 3, 4, 5, and 6 months than that in the control group (P<0.05 or P<0.01, respectively) CONCLUSION: YQSR could significantly reduce the amount of glomerular proteinuria in the early stage.

Integrin is a transmembrane receptor that mediates the connection between cells and their external environment, such as extracellular matrix (ECM). Integrin β4 (ITGβ4) plays a number of functions due to its special structures: forms α6β4 with ITGα6 subunit and participates in the formation of hemidesmosomes; mediates cell-to-cell matrix interaction and cell-to-cell interaction, cell proliferation and survival, as well as migration and invasion. Also, ITGβ4 participates in various disease processes by activating multiple signaling pathways. In this paper, the structure, physiological function and function of ITGβ4 in respiratory system, tumor, nervous system and other related diseases will be reviewed.

OBJECTIVETo observe the therapeutic effect of Yishen Qingre Huashi Recipe (YQHR) in treating proteinuria of chronic glomerular disease patients with Pi-Shen deficiency complicated damp-heat syndrome (PSDCDHS).

METHODSTotally 121 stage 1 -2 primary chronic glomerular disease patients with PSDCDHS were randomly assigned to the treated group (85 cases) and the control group (36 cases) according to 2:1. All patients received conventional and symptomatic treatment. Patients in the treated group took YQHR additionally, while those in the control group took Losartan Potassium Tablet (50 mg each time, once per day) additionally. The therapeutic course for all was 6 months. Changes of 24 h urine protein, blood urea nitrogen (BUN), serum creatinine(SCr), and estimated glomerular filtration rate (eGFR) were observed at different time points. And the difference in therapeutic effects were compared between the two groups.

RESULTSCompared with the control group after 6 months of treatment, 24 h urine protein obviously decreased in the treated group (P <0. 05). There was no statistical difference in SCr, BUN, or eGFR between the two groups after 6 months of treatment (P >0. 05). The total effective rate after 2, 4, and 6 months of treatment in the treated group was 77. 6% (66/85 cases), 82. 4% (70/85 cases), and 89. 4% (76/85 cases), respectively. They were 47. 2% (17/36 cases), 55. 6% (20/36 cases), and 61. 1% (22/36 cases) in the control group, respectively. Compared with before treatment in the treated group, the total effective effect after 6 months of treatment was higher than that after 2 months of treatment (χ2=4. 28, P <0. 01). Compared with the control group at the same time points, the total effective rate in the treated group after 2, 4, and 6 months of treatment was higher (χ2=10. 87, 9. 53, 13.16, P <0. 01).

CONCLUSIONYQHR could significantly lower proteinuria in chronic glomerular disease patients with PSDCDHS, improve the clinical effect, thereby providing clinical evidence for treating chronic glomerular disease proteinuria from resolving dampness and clearing heat.

5-Hydroxymethylfurfural (5-HMF), a water-soluble compound extracted from wine-processed Fructus corni, is a novel hepatic protectant for treating acute liver injury. The present study was designed to investigate the protective effect of 5-HMF in human L02 hepatocytes injured by D-galactosamine (GalN) and tumor necrosis factor-α (TNF-α) in vitro and to explore the underlying mechanisms of action. Our results showed that 5-HMF caused significant increase in the viability of L02 cells injured by GalN/TNF-α, in accordance with a dose-dependent decrease in apoptotic cell death confirmed by morphological and flow cytometric analyses. Based on immunofluorescence and Western blot assays, we found that GalN/TNF-α induced ER stress in the cells, as indicated by the disturbance of intracellular Ca(2+) concentration, the activation of protein kinase RNA (PKR)-like ER kinase (PERK), phosphorylation of eukaryotic initiation factor 2 alpha (eIF2α), and expression of ATF4 and CHOP proteins, which was reversed by 5-HMF pre-treatment in a dose-dependent manner. The anti-apoptotic effect of 5-HMF was further evidenced by balancing the expression of Bcl-2 family members. In addition, the knockdown of PERK suppressed the expression of phospho-PERK, phospho-eIF2α, ATF4, and CHOP, resulting in a significant decrease in cell apoptosis after the treatment with GalN/TNF-α. 5-HMF could enhance the effects of PERK knockdown, protecting the cells against the GalN/TNF-α insult. In conclusion, these findings demonstrate that 5-HMF can effectively protect GalN/TNF-α-injured L02 hepatocytes against ER stress-induced apoptosis through the regulation of the PERK-eIF2α signaling pathway, suggesting that it is a possible candidate for liver disease therapy.

Objective To observe the association between preprocedural high sensitivity C-reactive protein (hs-CRP) level and incidence of contrast induced acute kidney injury (CI-AKI) in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) and the impact of atorvastatin pretreatment on CI-AKI. Methods According to the level of preprocedural hs-CRP, 270 ACS patients were divided into three groups: high hs-CRP group (hs-CRP≥3 mg/L, n =176), moderate hsCRP group (hs-CRP 1 -3 mg/L, n =60) and normal hs-CRP group ( hs-CRP ＜ 1 mg/L, n =34).According to the dosage of preprocedural atorvastatin, the high hs-CRP group was further divided into 10 mg group (n =49), 20 mg group (n =66) and 40 mg group (n =61 ). Serum creatinine (Ser), blood urea nitrogen (BUN), cystatin C (Cys C), hs-CRP were measured at before and 24 hours, 48 hours after PCI.CCr and GFR were calculated according to Scr and Cys C. Risk factors for CI-AKI were determined by multivariate logistic regression analysis. Results ( 1 ) Cys C was significantly increased and GFR after PCI significantly reduced in high and moderate hs-CRP groups compared with normal hs-CRP group ( P ＜ 0. 05 ).(2) Incidence of CI-AKI was 43. 18％, 38. 33％ , 20. 59％ in high, moderate and normal hs-CRP groups,respectively (P ＜ 0. 05 ). (3) In high hs-CRP group, postprocedural GFR was significantly higher while postprocedural Cys C and hs-CRP were significantly lower in 40 mg statin subgroup than 10 mg and 20 mg statin subgroups (P ＜ 0. 05), similar trends were documented when comparing 20 mg statin subgroup with 10 mg statin subgroup ( P ＜ 0. 05 ). (4) Multivariate logistic regression analysis showed that pretreatment with high dose atorvastatin was a protective factor for post CI-AKI (20 mg atorvastatin: OR =0. 15, 95％ CI 0. 06 -0. 33, P =0. 00 1 ; 40 mg atorvastatin: OR =0. 10, 95 ％ CI 0. 04 -0. 23, P =0. 001 ), while high levels of preprocedural hs-CRP (OR =2. 06, 95％ CI 1.01 -4. 23, P =0. 048), diabetes mellitus (OR =10.71,95％ CI5.29 -21.70, P=0.001), advanced age (OR =2. 64, 95％ CI 1.05 -6. 63, P =0.038)and renal failure ( OR =5. 14, 95％ CI 1.13 - 23.39, P =0. 034 ) were independent risk factors of CIAKI. Conclusion High hs-CRP level is linked with the development of CI-AKI in ACS patients undergoing PCI and pretreatment with 40 mg atorvastatin is associated with lower incidence CI-AKI, possibly by reducing the postprocedural inflammation responses.
