Abstract
BACKGROUND To assess the outcome of human urinary kallidinogenase (HUK) plus recombinant tissue plasminogen activator (rT-PA) intravenous thrombolysis for stroke patients with an extended time window(4.5 to 9 h). METHODS A total of 92 acute ischemic stroke patients who fulfilled the criteria were included in this study. All patients received basic treatment and intravenous rT-PA, and 49 patients received additional injections of HUK (HUK group) once a day for 14 consecutive days. Outcomes were indicated by the thrombolysis in cerebral infarction score as the primary endpoint and the National Institute of Health Stroke Scale, modified Rankin Scale, and Barthel Index as the secondary endpoints. The safety outcomes were the rate of symptomatic intracranial hemorrhage, bleeding, angioedema, and mortality. RESULTS The National Institute of Health Stroke Scale scores were significantly lower in the HUK group at hospital discharge (4.55 ± 3.78 vs 7.88 ± 7.31, P = 0.009) and day 90 (4.04 ± 3.51 vs 8.12 ± 9.53, P = 0.011). The improvements in the Barthel Index scores were more obvious in the HUK group. Patients in the HUK group achieved favorable functional independence (67.35% vs 46.51%; odds ratio: 2.37; 95% CI: 1.01-5.53) at 90 days. The recanalization rate of the HUK group was 64.10%, whereas that was 41.48% in the control group ( P = 0.050). The complete reperfusion rates were 42.9% and 23.3% in the HUK group and the control group, respectively. No significant differences were observed for adverse events between the two groups. CONCLUSIONS Combination therapy of HUK plus rT-PA in patients with acute ischemic stroke with an extended time window can safely improve their functional outcomes.

Human Urinary Kallidinogenase Pretreatment Inhibits Myocardial Inflammation and Apoptosis after Coronary Microembolization by Activating PI3K/Akt/FoxO1 Axis. FRONT BIOSCI-LANDMRK 2022; 27:298. [PMID: 36336857 DOI: 10.31083/j.fbl2710298] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 08/28/2022] [Accepted: 09/06/2022] [Indexed: 01/07/2023]
Abstract
BACKGROUND As a fatal cardiovascular complication, coronary microembolization (CME) results in severe cardiac dysfunction and arrhythmia associated with myocardial inflammation and apoptosis. Human urinary kallidinogenase (HUK) can provide a protective function for cardiomyocytes by improving microcirculation. However, the therapeutic effects and underlying mechanisms of HUK in CME-induced myocardial injury remain unclear. AIMS We evaluated the effect of HUK on cardiac protection in a rat model of CME and whether it could restrain myocardial inflammation and apoptosis, and alleviate CME-induced myocardial injury. METHODS We established the CME model by injecting 42 μm inert plastic microspheres into the left ventricle of rats in advance, then the rats were randomly and equally divided into CME, CME + HUK (the dose of HUK at 0.016 PNA/kg/day), CME + HUK + LY (the dose of LY294002 at 10 mg/kg, 30 minutes before modeling), and Sham operation groups. Cardiac function, the serum levels of myocardial injury biomarkers, myocardial inflammation and apoptosis-related genes were measured; and the myocardial histopathological examination was performed at 12 h after the operation. RESULTS The results revealed that HUK effectively reducing myocardial inflammation, apoptosis, and myocardial infarction area; and improving CME-induced cardiac injury by activating the PI3K/Akt/FoxO1 axis. In addition, these cardioprotective effects can be reduced by the PI3K specific inhibitor LY294002, suggesting that the aforementioned protective effects may be related to activation of the PI3K/Akt/FoxO1 axis. CONCLUSIONS HUK seems to control inflammatory infiltration and cardiomyocyte apoptosis significantly to improve CME-induced cardiac injury via regulating the PI3K/Akt/FoxO1 axis.

Abstract
OBJECTIVES Some acute ischemic stroke (AIS) patients still suffer from early neurological deterioration (END) after receiving intravenous thrombolysis (IVT), and these patients often have a poor prognosis. The purpose of our study is to observe the efficacy and safety of human urinary kallidinogenase (HUK) treatment in patients with END. METHODS This was a retrospective analysis and 49 patients with END who met the inclusion criteria were divided into the observation group and the control group. All patients received routine treatment of AIS, while patients in the observation group were treated with HUK within 24 h after IVT and the other group without HUK. RESULTS There were 24 patients in the observation group and 25 patients in the control group. After treatment, favorable prognosis (mRS scores ≤2) at 3 months in the observation group with 13 cases (54.17%) was significantly better than that in the control group with four cases (16%) (p = .001), and there was no statistical difference between the two groups in any hemorrhagic complication. CONCLUSION HUK is considered to be safe and may improve the prognosis of AIS patients with END after IVT. More clinical trials are needed to validate these results in the future.

Abstract
INTRODUCTION Several studies have investigated the efficacy of human urinary kallidinogenase (HUK) combined with edaravone (Eda) in acute ischemic stroke (AIS) patients. Our aim was to provide the best available evidence for clinical practice and further research programs for stroke treatment. METHODS We searched the online database for paper published between January 2015 and April 2021. We calculated weighted mean difference (WMD) or odds risk (OR) and their corresponding 95% confidence interval (95% CI) of reported outcomes between HUK plus Eda and Eda groups for each study. The random-effect models or fixed-effect models were used to pool the analysis. RESULTS Thirteen studies with 1242 patients were included. In the pooled analysis, the scores of NIHSS in the HUK plus Eda group were significantly lower than that in patients receiving Eda (WMD = -3.92, 95% CI (-4.82, -3.02), p < .0001). The ADL scores in the HUK plus Eda group were significantly greater than that in patients receiving Eda (WMD = 14.13, 95% CI (10.67, 17.60), p < .0001). Furthermore, HUK plus Eda was associated with a higher rate of total efficacy (OR = 3.97, 95% CI (2.81, 5.59), p < .0001). CONCLUSIONS HUK combined with Eda provides potential clinical benefits as a treatment for AIS. Further high-quality, large-scale randomized trials are needed to confirm these results.

Abstract
Aims Human urinary kallidinogenase (HUK) has shown favorable efficacies in acute ischemic stroke (AIS) treatment. We sought confirmation of the safety and efficacy of HUK for AIS in a large population. Methods RESK study enrolled patients with AIS of anterior circulation to receive HUK infusion. The primary endpoint was the incidence of treatment‐emergent adverse events (AEs). Secondary endpoints assessed neurological and functional improvements and stroke recurrent rate. Results Of 1206 eligible patients, 1202 patients received at least one dose of HUK infusion and 983 (81.5%) completed the study. The incidence of treatment‐emergent AEs and serious AEs were 55.99% and 2.41%, respectively. Pre‐specified AEs of special interest occurred in 21.71% of patients, but the majority were mild and unrelated to therapy. Hypertension, age, treatment time, and drug combination were identified to be associated with drug‐related blood pressure reduction. Neurological and functional evaluations revealed favorable outcomes from baseline to post‐treatment assessment. The cumulative recurrence rate of stroke was 2.50% during the 90‐day assessment. Conclusion HUK had an acceptable safety and tolerability profile in AIS patients. Besides, HUK demonstrated the neurological and functional improvements in AIS, further confirming its clinical efficacy in a real‐world large population.

Abstract
OBJECTIVE To compare the e!cacy and functional outcomes of dl-3-n-Butylphthalide (NBP) and human urinary kallidinogenase (HUK) on ischemic stroke patients and to determine their effects on serum tumor necrosis factor-alpha (TNF-α) and vascular endothelial growth factor (VEGF). METHODS A prospective study was conducted on 57 ischemic stroke patients. Functional outcomes were assessed by the National Institute Health Stroke Scale (NIHSS), the modified Rankin Scale (mRS), and the activities of daily living score (ADL), whereas TNF-α and VEGF expressions were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS TNF-α was significantly down-regulated in the NBP group and upregulated in the control group two weeks after treatment (p=0.017 and p=0.047, respectively). A significant difference in VEGF expressions was observed between the two groups (330.25±120.64 vs. 437.15±137.68, p=0.041) two weeks after treatment. Both groups showed significant improvement in NIHSS and ADL scores three months after treatment (p<0.001), with the NBP group exhibiting improvement in NIHSS scores as early as two weeks after treatment (p=0.008). The three-month NIHSS scores of the two groups were significantly lower than those of the control group (p=0.010 and p=0.008, respectively). Both the NBP and HUK groups showed a significant decline in mRS scores two weeks and three months after treatment (p<0.05). CONCLUSIONS Both treatments are effective and can significantly promote recovery in stroke patients. Additionally, both options have similar effects in promoting long-term recovery, with NBP exerting a greater impact on serum VEGF and TNF-α expressions.

Abstract
INTRODUCTION To evaluate effectiveness of human urinary kallindinogenase (HUK) in patients with acute ischemic stroke (AIS) according to Chinese ischemic stroke subclassification (CISS) and analyzed risk factors of clinical efficacy. METHODS In this retrospective study, 134 patients received conventional therapy were enrolled to control group, and 132 patients received HUK treatment were enrolled to HUK group. National Institute of Health Stroke Scale (NIHSS) score was used to evaluate the clinical efficacy. Multivariate analysis of risk factors was performed by using logistic regression. RESULTS After treatment, NIHSS score of HUK group was significant lower than that of control group (p = .009). Effectiveness rate was 71.2% in HUK group, and 53.7% in control group, respectively (p = .003). The NIHSS of patients with large artery atherosclerosis (LAA) subtype in HUK group was significantly lower than that in control group (p = .005). The absence of HUK (OR = 2.75), homocysteine (OR = 0.15), and CS subtype (OR = 0.18) were risk factors for HUK clinical efficacy. CONCLUSIONS Human urinary kallindinogenase is an effective therapeutic approach for treatment of patients with AIS, especially in patients with LAA subtype. The absence of HUK, elevated homocysteine, and cardiogenic stroke subtype were risk factor for clinical efficacy of HUK.

Abstract
AIM The effectiveness of neuroprotective agents is still unclear. Here we analyzed the clinical outcomes of acute ischemic stroke (AIS) patients treated with human urinary kallidinogenase (HUK) or edaravone (Eda) combined with butylphthalide (NBP). METHODS From January 2016 to December 2017, a total of 165 AIS patients were enrolled in this open-label, randomized controlled clinical study. Patients were randomly allocated into HUK group and Eda group in a ratio of 2:1. All the patients received basic treatments and NBP (200 mg p.o. qid) while HUK group received 0.15 PNA unit of HUK injection (ivgtt. qd) and Eda group received 30 mg Eda (ivgtt. bid) for 14 consecutive days. Independency rate [12-month modified Rankin Scale (mRS) score ≤ 1] and related factors were compared between the two groups. RESULTS Twelve-month mRS score of the HUK group (1, IQR 0~1) was significantly lower compared with Eda group (2, IQR 1~3, p < .0001). The HUK treatment achieved an independency rate of 79.1% while the Eda treatment only had 45.3% (p < .0001). Further binary logistic regression showed that recurrent stroke (RR: 0.1, 95% CI: 0.0~0.1, p = .038) and HUK treatment (RR: 4.2, 95% CI: 1.1~16.5, p = .041) could significantly affect patients' 12-month outcomes. CONCLUSION Human urinary kallidinogenase combined with NBP can enhance AIS patients' long-term independency rate, and the effectiveness of HUK combined therapy is better than Eda.

The Combination of Human Urinary Kallidinogenase and Mild Hypothermia Protects Adult Rats Against Hypoxic-Ischemic Encephalopathy-Induced Injury by Promoting Angiogenesis and Regeneration. Front Aging Neurosci 2018; 10:196. [PMID: 30050428 PMCID: PMC6050362 DOI: 10.3389/fnagi.2018.00196] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2018] [Accepted: 06/11/2018] [Indexed: 12/14/2022] Open
Abstract
Objectives: Human Urinary Kallidinogenase (HUK) is a tissue kallikrein that plays neuroprotective role in ischemic conditions via different mechanisms. Mild hypothermia (MH) is another robust neuroprotectant that reduces mortality but does not profoundly ameliorate the neurological outcome in hypoxic-ischemic encephalopathy (HIE) patients. However, whether the combination of HUK and MH can be used as a promising neuroprotective treatment in HIE is unknown. Methods: One-hundred and forty-four adult Wistar rats were randomly divided into five groups: Sham, HIE, HUK, MH and a combination of HUK and MH treatment. The HIE rat model was established by right carotid dissection followed by hypoxia aspiration. The survival curve was created within 7 days, and the neurological severity scores (NSS) were assessed at days 0, 1, 3, and 7. Nissl staining, Terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL), immunofluorescent staining and western blotting were used to evaluate neuronal survival, apoptosis and necrosis, tight-junction proteins Claudin-1 and Zonula occludens-1 (ZO-1), vascular endothelial growth factor (VEGF), doublecortex (DCX), bradykinin receptor B1 (BDKRB1), BDKRB2 and Ki67 staining. Results: The combined treatment rescued all HIE rats from death and had a best survival curve compared to HIE. The Combination also reduced the NSS scores after HIE at days 7, better than HUK or MH alone. The combination of HUK and MH reserved more cells in Nissl staining and inhibited neuronal apoptosis and necrosis as well as significantly attenuated HIE-induced decreases in claudin-1, ZO-1, cyclin D1 and BDKRB1/B2 in comparison to HUK or MH treatment alone. Moreover, the combined treatment increased the expression of VEGF and DCX as well as the number of Ki67-labeled cells. Conclusions: This study demonstrates that both HUK and MH are neuroprotective after HIE insult; however, the combined therapy with HUK and MH enhanced the efficiency and efficacy of either therapy alone in the treatment of HIE, at least partially by promoting angiogenesis and regeneration and rescuing tight-junction loss. The combination of HUK and MH seems to be a feasible and promising clinical strategy to alleviate cerebral injury following HIE insult. Highlights: -The combination of HUK and MH distinctly reduces neurological dysfunction in HIE rats.-HUK enhances the neuroprotective effects of MH in HIE.-MH attenuates tight-junction disruption, upregulates the BDKR B1/2, DCX and cyclin D1.-The combination of MH and HUK enhances the expressions of MH/HUK mediated-BDKR B1/2, DCX, cyclin D1 and Ki67 positive cells.

Abstract
The term “tissue kallikrein” is used to describe a group of serine proteases shared considerable sequence homology and colocalize in the same chromosomal locus 19q13. 2–q13.4. It has been widely discovered in various tissues and has been proved to be involved in kinds of pathophysiological processes, such as inhibiting oxidative stress, inflammation, apoptosis, fibrosis and promoting angiogenesis, and neurogenesis. Human Urinary Kallidinogenase (HUK) extracted from human urine is a member of tissue kallikrein which could convert kininogen to kinin and hence improve the plasma kinin level. Medical value of HUK has been widely investigated in China, especially on acute ischemic stroke. In this review, we will summarize the therapeutic values of Human Urinary Kallidinogenase on acute ischemic stroke and its potential mechanisms.

Abstract
Aims: To evaluate the clinical efficacy of Human Urinary Kallidinogenase (HUK) and Maixuekang capsule in the treatment of acute ischemic stroke (AIS) patients. Methods: In this study, from January 2016 to July 2016, 60 patients with acute ischemic stroke were enrolled and 56 patients with complete information of whom 21 patients received HUK+ basic treatment (HUK group), 16 patients received HUK+ Maixuekang capsule + basic treatment (HUK+ Maixuekang group), 19 patients received basic treatment (control group). 0.15 PNA unit of HUK injection plus 100 ml saline in intravenous infusion was performed in the HUK group and HUK+ Maixuekang group, with once a day for 14 consecutive days. 0.75 g Maixuekang capsules were taken in HUK+ Maixuekang group, with three times a day for 14 consecutive days. The National Institutes of Health Stroke Scale (NIHSS) scores in three groups were analyzed 7 days after treatment. The modified Rankin Scale (mRS) scores in three groups were analyzed 12 month after the treatment. Results: No difference was found in the NIHSS scores, age, gender, and comorbidities between three groups before treatment (p > 0.05). Seven days after treatment, the NIHSS scores in the HUK group and HUK+ Maixuekang group were significantly decreased than before (p HUK = 0.001, p HUK+Maixuekang < 0.001), and lower than that in the control group (p HUK = 0.032; p HUK+Maixuekang < 0.001). Twelve months after treatment, good functional outcome rate (12 month mRS score ≤ 2) in the HUK group and HUK+ Maixuekang group was significantly higher than that in the control group (p HUK = 0.049, p HUK+Maixuekang = 0.032). Conclusion: The treatment of HUK or HUK combined with Maixuekang capsule can effectively improve the neurological function and promote long-term recovery for AIS patients.

Abstract
AIM To evaluate the clinical efficacy of Human Urinary kallidinogenase (HUK) in the treatment of acute ischemic stroke (AIS) patients with level 3 hypertension. METHODS In this retrospective study, from January 2015 to June 2016, 150 consecutive AIS patients were registered in our database. Among them, 47 with level 3 hypertension received either HUK treatment (HUK group, 22 cases) or basic treatment (control group, 25 cases). Basic treatment was administrated on all patients. 0.15 PNA unit of HUK injection plus 100 ml saline in intravenous infusion was performed in the HUK group, with once a day for 14 consecutive days. The modified Rankin Scale (mRS) scores in two groups were analyzed 3 months after the treatment. RESULTS No difference was found in the NIHSS scores, age, gender, and comorbidities between two groups before treatment (p > .05). While after treatment, 3-month mRS score was significantly lower in the HUK group (2.1 ± 1.4 vs. 3.1 ± 1.3, p = .012) and good recovery rate (3-month mRS score ≤2) in the HUK group was significantly higher than that in the control group (p < .05). CONCLUSION HUK is able to promote long-term recovery for AIS patients with level 3 hypertension remarkably.

Abstract
A total of 29 patients were treated within 48 hours after acute subcortical cerebral infarction with Xuesaitong or Xuesaitong plus human urinary kallidinogenase for 14 days. Neurological deficits, activity of daily living, and evaluations of distal upper limb motor functions at the 6-month follow-up showed that patients treated with Xuesaitong plus human urinary kallidinogenase recovered better than with Xuesaitong alone. In addition, functional MRI revealed that activation sites were primarily at the ipsilesional side of injury in all patients. Human urinary kallidinogenase induced hyperactivation of the ipsilesional primary sensorimotor cortex, premotor cortex, supplementary motor area, and contralesional posterior parietal cortex. Results showed that human urinary kallidinogenase improved symptoms of neurological deficiency by enhancing remodeling of long-term cortical motor function in patients with acute cerebral infarction.

The purpose of this study is to investigate the possible mechanism and the neuroprotective effect of human urinary kallidinogenase (HUK) in cerebral ischemia. The mouse middle cerebral artery occlusion (MCAO) model was used. Mice were treated with HUK (20 PNAU/g per day, intravenous) or saline as control, from the beginning of reperfusion to 72 h. Neurological deficits, infarct size, and BWC were measured at 6, 24, 48, and 72 h after MCAO, respectively. Pathological changes of brain were observed by TUNEL assay. Inflammatory factors were measured by real-time PCR and western blotting. Activation of MAPKs, Akt, and nuclear factor-kappaB (NF-kappaB) was detected by western blotting. Our results indicated that HUK significantly improved neurofunction, decreased infarct size, and suppressed edema, as well as inflammatory mediators as compared with the vehicle group. Furthermore, HUK inhibited the NF-kappaB pathway and activated the MAPK/ERK pathway in this neuroprotection.
