Objective To explore the effect of cinepazide maleate on serum inflammatory factors of intensive care unit (ICU) patients with severe cerebral hemorrhage after surgery. Methods 116 ICU patients with severe cerebral hemorrhage treated in Taian Maternal and Child Health Hospital from June 2018 to June 2020 were selected as the research objects and randomly divided into the control group and experimental group, with 58 patients in each group. The control group was given routine treatment, while the experimental group was additionally given an intravenous drip of cinepazide maleate to compare the clinical efficacy and serum inflammatory factors between the two groups. Results The total effective rate in the experimental group was higher than that in the control group (P < 0.05). After treatment, the Glasgow Coma Scale (GCS), National Institutes of Health Stroke Scale (NIHSS), and Fugl-Meyer scores in both groups were better than those before treatment, and the scores in the experimental group were better than those in the control group (P < 0.05). The oxidative stress indexes such as total antioxidant capacity (T-Aoc), superoxide dismutase (SOD), and glutathione peroxidase (GSH-PX) in the experimental group were higher than those in the control group, while malondialdehyde (MDA) in the experimental group was lower than that in the control group (P < 0.05). The high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) levels in the experimental group were lower than those in the control group (P < 0.05). Compared with the control group, the cerebrovascular function in the experimental group was significantly improved (P < 0.05), with statistically significant differences. Conclusion Cinepazide maleate can effectively reduce the serum inflammatory factor levels of ICU patients with severe cerebral hemorrhage after surgery, alleviate the oxidative stress response in the body, and improve the cerebrovascular function and cerebral nerve function, which is worthy of clinical promotion.


Introduction
Cerebral hemorrhage (also known as spontaneous intracerebral hemorrhage) refers to nontraumatic primary intraparenchymal hemorrhage, accounting for about 20%-30% of acute cerebrovascular diseases [1][2][3][4]. According to clinical statistics, about 80% of patients have cerebral hemorrhage in the cerebral hemisphere, with the remaining 20% in the cerebellum and brainstem. Cerebral hemorrhage is a type of acute cerebrovascular disease with the highest mortality rate, mostly in elderly patients over 50 years old or in patients with a history of hypertension. In clinical treatment, most patients receive medical treatment. In the acute phase, bleeding control and reducing intracranial pressure are the main measures, and supportive medical care is necessary after cerebral hemorrhage is stopped [5][6][7][8]. Cinepazide maleate is a calcium channel blocker to inhibit Ca 2+ influx, relax the vascular smooth muscle, and dilate coronary arteries. In clinical studies, animal experiments have confirmed that this substance has a certain inhibitory effect on the inflammatory response in the process of focal cerebral ischemia-reperfusion injury in rats, protecting the brain [9][10][11][12]. In recent years, the medical research about cinepazide maleate mostly focuses on its effect on hypertensive cerebral hemorrhage (HICH) and lacks studies on severe cerebral hemorrhage. To further clarify the clinical effect of cinepazide maleate on patients with severe cerebral hemorrhage, this paper explored the effect of cinepazide maleate on serum inflammatory factor levels of ICU patients with severe cerebral hemorrhage after surgery, summarized as below.

Methods.
e control group received routine treatment measures immediately after admission, specifically as follows. (1) Dehydration: the patients with cerebral edema received 250 ml of 20% mannitol injection (specification: 250 ml/bottle; manufacturer: Shandong Wego Pharmaceutical Co., Ltd.; SFDA approval no. H20053865) by intravenous drip, 1-2 times a day. e dosage and treatment courses could be adjusted according to the severity of cerebral edema [14]. (2) Anticoagulation: 5000 IU of lowmolecular-weight heparin calcium (1.0 ml: 5000 Axa unit; manufacturer: Shenzhen Scriprogen Biopharmaceutical Co., Ltd.; SFDA approval no. H20060190) was injected subcutaneously into the abdominal wall around the umbilicus every 12 hours. 80 mg of ozagrel sodium (specification: 40 mg; manufacturer: Youcare Pharmaceutical Group Co., Ltd.; SFDA approval no. H20063851) and 250 ml of sodium chloride injection were injected into the patients by intravenous drip, twice a day. e patients also orally took 0.1 g of aspirin enteric-coated tablets (specification: 100 mg/tablet; manufacturer: Bayer Schering Pharmaceutical Health Co., Ltd.; SFDA approval no. J20130078) once a day and continuously for 12 months. (3) Brain protection: the patients received 30 mg of edaravone injection (specification: 30 mg/ vial; manufacturer: Nanjing Simcere Dongyuan Pharmaceutical Co., Ltd.; SFDA approval no. H20031342) and 250 ml of 0.9% sodium chloride injection by intravenous drip, twice a day. (4) Hyperbaric oxygen: hyperbaric oxygen therapy (HBOT) at atmospheric pressure (2.026 × 10 5 Pa) was performed at 1 hour after thrombolysis, and each time lasted for 1 hour, once a day. (5) Symptomatic treatment: patients with hypertension and diabetes received antihypertensive and hypoglycemic treatment, respectively. In addition, it was necessary to prevent infection and maintain the water-electrolyte balance of patients. e experimental group was additionally treated with cinepazide maleate. e patients received 240 mg of cinepazide maleate injection (specification: 320 mg/vial; manufacturer: Beijing Sihuan Pharmaceutical Co., Ltd.; SFDA approval no. H20061204) and 250 ml of 0.9% sodium chloride injection by intravenous drip, once a day. e routine treatment was the same with that in the control group. During the treatment, all patients were prohibited from using other cerebral vasodilators, Ca 2+ antagonists, or nootropic agents. e treatment lasted for 14 days in both groups. [15], the neurological deficit score of patients decreased by more than 90% after treatment, with the disability grade as 0, which was cured. e neurological deficit score decreased by 46%-90%, with the disability grade as levels 1-3, which was markedly effective. e neurological deficit score decreased by 18%-45%, which was improved. e neurological deficit score decreased by less than 17%, which was ineffective. Total effective rate � (improved + markedly effective + cured)/total number × 100%.

Evaluation of Neurological Function. Glasgow Coma
Scale (GCS) was used to evaluate the coma degree, including eye opening response (4 points), verbal response (5 points), and motor response of the nonhemiplegia side (6 points), with a total score of 15 points. A score of 8 or less was considered as coma, and a higher score represented a lower level of coma in patients. e National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the neurological deficits, including 11 large dimensions (consciousness, gaze, visual field, facial paralysis, upper limb movement, lower limb movement, ataxia, sensation, language, dysarthria, and neglect), with a total score of 42 points. A higher score represented more serious neurological deficits. Fugl-Meyer motor function measure scale was used to evaluate the comprehensive motor function of patients, with 17 items and a total score of 100 points. e score <50 was considered as severe dyskinesia, 50-84 as obvious dyskinesia, 85-95 as moderate dyskinesia, and 96-99 as mild dyskinesia.

Oxidative Stress Indexes.
Fasting venous blood from the elbow was taken in the morning and centrifuged at 4000 r/min for 5 min. After the supernatant was placed in an Eppendorf tube, the total antioxidant capacity (T-Aoc) kits (specification: 50T/48S; brand: Solarbio) were used to detect the T-Aoc levels, superoxide dismutase (SOD) activity kits (specification: 50T/24S; brand: Solarbio) were used to detect the SOD level, glutathione peroxidase (GSH-PX) kits (specification: 50T/343T; manufacturer: Shanghai Caiyou Industrial Co., Ltd.) were used to detect the GSH-PX level, and malondialdehyde (MDA) kits (specification: 100T/96S; brand: Solarbio) were used to detect the MDA level of patients.
Venous blood was collected from patients, and serum was separated. Enzyme-linked immunosorbent assay (ELISA) was used to detect the total antioxidant capacity (T-Aoc), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), and malondialdehyde (MDA) levels of patients.

Discussion
Hypertensive cerebral hemorrhage (HICH) is a common high-risk disease in clinics, and most patients in clinics mainly receive medical treatment. If patients with surgical indications have more serious condition or their secondary cause is found, surgical treatment will be adopted to mainly reduce intracranial pressure, remove hematoma, and save the life of patients. In addition, patients need to control blood pressure to reach the standard and be stable for life [16]. e prognosis of the disease is often related to the amount of bleeding, bleeding sites, and complications. Patients are considered to have good prognosis if they experience a small amount of blood loss with no bad complications during treatment, and their bleeding sites do not affect the neurological function. Patients have poor prognosis if they suffer from complications such as pulmonary infection and gastrointestinal bleeding [17][18][19][20]. Clinical statistics suggest that severe intracerebral hemorrhage can account for about half of intracerebral hemorrhage cases. Failure to take timely and effective measures will directly affect the recovery of patients after intervention, leading to sequelae or even death. In recent years, the medical research about cinepazide maleate mostly focuses on its effect on HICH and lacks studies on severe cerebral hemorrhage. erefore, this paper retrospectively analyzed the clinical data of 116 ICU patients with severe cerebral hemorrhage treated in our hospital, observed their serum inflammatory factor levels, and explored the clinical effect of Evidence-Based Complementary and Alternative Medicine cinepazide maleate on the patients, neurological function, inflammatory response, and oxidative stress injury, aiming to provide a reference for the optimization of clinical therapeutic schedules for ICU patients with severe cerebral hemorrhage.
Cinepazide maleate injection is a Ca 2+ antagonist that can prevent Ca 2+ from penetrating into vascular smooth muscle cells across the membrane and relax the vascular smooth muscle, thereby expanding cerebral, peripheral, and coronary vessels to relieve vasospasm, reduce vascular resistance, and increase blood flow. In addition, cinepazide maleate can enhance the role of cyclic adenosine monophosphate and adenosine, reduce oxygen consumption, and increase the content of cyclic adenosine monophosphate by inhibiting cAMP phosphodiesterase. In addition, it can improve the deformability and flexibility of red blood cells to enhance their ability to pass through small blood vessels, thereby reducing blood viscosity and improving microcirculation [21][22][23][24]. is   Evidence-Based Complementary and Alternative Medicine study showed that the total effective rate in the experimental group was higher than that in the control group, indicating that cinepazide maleate can improve the postoperative therapeutic effect of patients with cerebral hemorrhage compared with routine treatment. After treatment, the GCS, NIHSS, and Fugl-Meyer scores in both groups were better than those before treatment, and the scores in the experimental group were better than those in the control group (P < 0.05). GCS was mainly used to evaluate the coma degree of patients with cerebral hemorrhage, NIHSS was to evaluate the neurological deficits, and Fugl-Meyer reflected the comprehensive motor function. It can be seen that cinepazide maleate can effectively enhance the postoperative neurological function of patients, improve brain metabolism, and promote the recovery of brain function. e oxidative stress indexes such as T-Aoc, SOD, and GSH-PX in the experimental group were higher than those in the control group, while MDA in the experimental group was lower than that in the control group. e hsCRP, IL-6, IL-8, and TNF-α levels in the experimental group were lower than those in the control group. Compared with the control group, the cerebrovascular function in the experimental group was significantly improved. Oxidative stress response and inflammatory response are closely related to the pathological changes of nerve injury and edema in patients with cerebral hemorrhage. After cerebral hemorrhage, hematoma occurs rapidly in the lesion area, resulting in the death of a large number of brain nerve cells around the lesions. At the same time, the blood supply area of the bleeding vessel forms reperfusion injury which produces lots of inflammatory factors and then leads to systemic inflammatory response. e further development of inflammation will bring about microglia activation, infiltration of inflammatory cells around the lesions, and release of proinflammatory mediators, eventually resulting in cell death and brain injury. If the inflammatory response is not timely controlled, it will also aggravate the risk of secondary injury after cerebral hemorrhage. When cerebral hemorrhage occurs, the brain tissue will also suffer from oxidative damage, which is a potential damage state in which the oxides and antioxidants in the body lose their dynamic balance. Under the common effect of inflammatory factors, lots of oxygen free radicals are generated in the lesion area, aggravating the damage of surrounding nerve cells. In addition, oxygen free radicals can also form the blood-brain barrier, causing systemic oxidative stress injury. erefore, it is of great significance to improve the inflammatory factor levels and oxidative stress response for the postoperative treatment of patients. In summary, the implementation of cinepazide maleate-combined routine treatment after surgery has a positive effect on patients with severe cerebral hemorrhage, which can improve the cerebral blood flow, promote microcirculation, and have good anti-inflammatory effect, thereby reducing cerebral damage. Jia et al. [25] believed that cinepazide maleate had the effect of reducing serum inflammatory factor levels and blood viscosity and had a good clinical therapeutic effect on cerebral hemorrhage, which is consistent with the results of this study. e study has some shortcomings. For example, it is a single-center study with a small sample size, and the clinical efficacy of cinepazide maleate needs to be further verified by multicenter studies with an expanded sample size. In addition, this study lacks the observation and analysis of the long-term efficacy of patients.
In conclusion, cinepazide maleate can effectively reduce the serum inflammatory factor levels of ICU patients with severe cerebral hemorrhage after surgery, alleviate the oxidative stress response in the body, and improve the cerebrovascular function and cerebral nerve function, which is worthy of clinical promotion.
