An ultrasmall PVP-Fe-Cu-Ni-S nano-agent for synergistic cancer therapy through triggering ferroptosis and autophagy.

Photothermal therapy (PTT) is an emerging field where photothermal agents could convert visible or near-infrared (NIR) radiation into heat to kill tumor cells. However, the low photothermal conversion efficiency of photothermal agents and their limited antitumor activities hinder the development of these agents into monotherapies for cancer. Herein, we have fabricated an ultrasmall polyvinylpyrrolidone (PVP)-Fe-Cu-Ni-S (PVP-NP) nano-agent via a simple hot injection method with excellent photothermal conversion efficiency (∼96%). Photothermal therapy with this nano-agent effectively inhibits tumor growth without apparent toxic side-effects. Mechanistically, our results demonstrated that, after NIR irradiation, PVP-NPs can induce ROS/singlet oxygen generation, decrease the mitochondrial membrane potential, release extracellular Fe2+, and consume glutathione, triggering autophagy and ferroptosis of cancer cells. Moreover, PVP-NPs exhibit excellent contrast enhancement according to magnetic resonance imaging (MRI) analysis. In summary, PVP-NPs have a high photothermal conversion efficiency and can be applied for MRI-guided synergistic photothermal/photodynamic/chemodynamic cancer therapy, resolving the bottleneck of existing phototherapeutic agents.

CuS-NiS2 nanomaterials for MRI guided phototherapy of gastric carcinoma via triggering mitochondria-mediated apoptosis and MLKL/CAPG-mediated necroptosis.

Gastric carcinoma is one of the most lethal malignant tumors. As part of our long-term efforts on seeking effective diagnosis and therapeutic strategies of gastric cancer, we present herein novel ternary copper-based chalcogenide nanoplatform CuS-NiS2 nanomaterials with outstanding photothermal (PT)/photodynamic (PD) property that could effectively suppress human gastric cancer in vitro and in vivo without obvious side effects. We revealed that CuS-NiS2 induced reactive oxygen species (ROS) generation, leading to apoptosis through Bcl-2/Bax pathway of human gastric cancer cells under 808 nm near-infrared (NIR) irradiation. In addition, we also confirmed that the combination of CuS-NiS2 and 808 nm NIR laser treatment triggered necroptosis by regulating the novel pathway MLKL/CAPG of human gastric cancer cells. Moreover, the CuS-NiS2 exhibited excellent contrast enhancement according to magnetic resonance imaging (MRI). Taken together, we reported new ternary copper-based chalcogenide nanomaterials CuS-NiS2, which could be successfully applied for MRI-guided PT/PD therapy of gastric carcinoma through mitochondria-mediated apoptosis and MLKL/CAPG-mediated necroptosis.

Polysaccharide from flammuliana velutipes improves colitis via regulation of colonic microbial dysbiosis and inflammatory responses.

The aim of this study is to investigate whether Flammuliana Velutipes Polysaccharide (FVP) could aid in the prevention of colitis. Effect of FVP on colitis was evaluated using dextran sulfate sodium (DSS)-induced colitis in rats. Influence of FVP on the expression of inflammation related biomarkers and signal pathway element of TLR4\NF-κB were assessed. The composition and taxonomy of colonic microbiota were analyzed by 16S rDNA high throughput sequencing, and the concentrations of caecal short fatty chain acids were assessed by chromatography-mass spectrometry. Our results showed that FVP treatment could regulate the colonic microbial dysbiosis and promote the levels of caecal short fatty chain acids, leading to down-regulation of TLR4\NF-κB signal pathway, which finally ameliorate the colitis. Thus, the present study is the first attempt to elucidate the effect of FVP on colitis and support the potential application of FVP as a functional food ingredient or preventive drugs for colitis.

The Application of Ferric Chloride-Lignin Sulfonate as Shale Inhibitor in Water-Based Drilling Fluid.

A series of ferric chloride-lignin sulfonate (FCLS) was prepared from ferric chloride and lignin sulfonate to be used as shale inhibitor. The swelling rate of clay with FCLS-2 (w/w = 0.3%) decreased to 41.9%. Compared with control, FCLS-2 displayed high inhibitive ability against the hydrating and swelling processes of clay. Thus, the swelling degree of samples with FCLS-2 was much lower than that of the control, as well as the mud ball was more stable in FCLS-2 solution. Essentially, these excellent performances in inhibitor were assigned to the hydrogen bonding, electrostatic interaction and anchoring between FCLS-2 and other components. In addition, FCLS-2 has good compatibility with other common drilling fluid additives, and it can reduce the viscosity of systems, regardless of the room temperature or high temperature.

CuS-MnS2 nano-flowers for magnetic resonance imaging guided photothermal/photodynamic therapy of ovarian cancer through necroptosis.

With a high incidence and high mortality rate, ovarian cancer presents a challenge for clinical practice. It is thus extremely urgent to investigate new diagnosis and therapy methods for the treatment of ovarian cancer. Ternary copper-based chalcogenide nanomaterials are attractive owing to their near infrared (NIR) response for cancer theranostic fields. However, improving the theranostic efficiency of these nanomaterials is challenging. Herein, CuS-MnS2 nano-flowers were easily synthesized and under NIR irradiation exhibited a relatively high photothermal conversion efficiency of 67.5% and a simultaneous reactive oxygen species (ROS) generation effect. Owing to these outstanding photothermal/photodynamic effects, excellent tumor ablation results could be achieved by the combined use of CuS-MnS2 nano-flowers and 808 nm NIR laser treatments. The main anticancer mechanism of CuS-MnS2 nano-flowers + NIR was likely necroptosis. In addition, the nano-flowers showed remarkable contrast enhancement according to magnetic resonance imaging (MRI). These CuS-MnS2 nano-flowers could thus serve as a promising multifunctional nanotheranostic agent for MRI and as a photothermal/photodynamic cancer therapy agent through necroptosis.

[Influence of acupuncture plus moxibustion on changes of synaptic structure and expression of synaptic skeleton related genes and proteins in prefrontal cortex of heroin re-addicted rats].

OBJECTIVE: To observe the effect of acupuncture plus moxibustion on the synaptic ultrastructure and expression of synaptic skeleton related proteins in the prefrontal cortex (PFC) of heroin re-addicted rats, so as to reveal its mechanisms underlying improvement of heroin addiction. METHODS: Twenty-four Wister rats (half male and half female) were randomly divi-ded into normal control, model and acupuncture groups (n＝8 in each group). The heroin re-addicted model was established by muscular injection of heroin into the hind limbs for 8 days (incremental 0.8-3.6 mg, once daily for 6 days, and twice daily for 2 days), followed by conventional breeding for 5 days (detoxification), the procedure (addition－detoxification) was repeated 3 cycles. For rats of the acupuncture group, "Baihui" (GV20) was needled with filiform needles which were retained for 30 min, and moxibustion was then applied to bilateral "Shenshu" (BL23) for 30 min. The treatment was conducted once daily during the deto-xification. On the 39th day of experiment, the bilateral prefrontal cortex tissues were sampled for examining the ultrastructure by using transmission electron microscope (TEM) after fixative solution immersion and for determining the expression of genes and proteins of activity-regulated cytoskeleton-associated protein (Arc), microtubule-asso-ciated protein-2 (MAP-2) and microtubule-associated protein Tau (Tau) with quantitative real-time PCR and Western blot, respectively. RESULTS: After modeling, the expression levels of Arc mRNA and protein were significantly up-regulated, and those of MAP-2 and Tau mRNA and proteins ob-viously down-regulated in the model group relevant to the normal control group (P<0.05). Following the intervention, the up-regulated Arc protein and mRNA and the down-regulated MAP-2 and Tau were obviously reversed relevant to the model group (P<0.05). Outcomes of TEM showed unclear pre- and post-membranes of the synapses, narrowing of the synaptic gap and non-uniform of the density of the thickened dense plaque after modeling, which was relatively milder in the acupuncture group. CONCLUSION: Acupuncture plus moxibustion can improve changes of synaptic ultrastructure in heroin re-addicted rats, which may be related to their effect in regulating the expression of some synaptic skeleton proteins and genes.

Cord-derived mesenchymal stem cells therapy for liver cirrhosis in children with refractory Henoch-Schonlein purpura: A case report.

RATIONALE: To explore the curative effect of human umbilical cord-derived mesenchymal stem cell (ucMSC) therapy for patients with liver cirrhosis complicated with immune thrombocytopenia and refractory Henoch-Schonlein purpura (HSP). PATIENT CONCERNS: A 12-year-old boy presented to our hospital with an 11-month history of purpura on the skin of both lower limbs accompanied by thrombocytopenia. The patient had a history of repeated swelling and painful dorsum pedis, followed by skin redness. DIAGNOSIS: Bone marrow slides showed megakaryocyte maturation disorder. Based on the pathology and drug abuse history, he was diagnosed with nodular cirrhosis, secondary allergic purpura, and thrombocytopenia, etiologies related to his drugs and an immune dysfunction. INTERVENTIONS: ucMSC transplantation was performed, the liver damaging drugs were discontinued, and the appropriate liver immunosuppressive drugs were administered. ucMSCs were injected 8 times/wk in 2 months, with a median cell count of 5.65 × 10/L, ranging from 5.48 to 5.98 × 10/L. OUTCOMES: As the patient's skin rash resolved, his platelets gradually increased to >150 × 10/L and liver transaminase levels gradually decreased to a normal level. Ultrasonography of the abdomen indicated that the round nodules in the liver decreased in size and that the spleen thickness also decreased. LESSONS: This is a unique case of significant HSP with associated thrombocytopenia in a patient with liver cirrhosis. Long-term oral administration of excessive herbal medicine may cause liver damage. We believe that ucMSCs provide a novel approach for the treatment of liver cirrhosis.

PQQ ameliorates D-galactose induced cognitive impairments by reducing glutamate neurotoxicity via the GSK-3ß/Akt signaling pathway in mouse.

Oxidative stress is known to be associated with various age-related diseases. D-galactose (D-gal) has been considered a senescent model which induces oxidative stress response resulting in memory dysfunction. Pyrroloquinoline quinone (PQQ) is a redox cofactor which is found in various foods. In our previous study, we found that PQQ may be converted into a derivative by binding with amino acid, which is beneficial to several pathological processes. In this study, we found a beneficial glutamate mixture which may diminish neurotoxicity by oxidative stress in D-gal induced mouse. Our results showed that PQQ may influence the generation of proinflammatory mediators, including cytokines and prostaglandins during aging process. D-gal-induced mouse showed increased MDA and ROS levels, and decreased T-AOC activities in the hippocampus, these changes were reversed by PQQ supplementation. Furthermore, PQQ statistically enhanced Superoxide Dismutase SOD2 mRNA expression. PQQ could ameliorate the memory deficits and neurotoxicity induced by D-gal via binding with excess glutamate, which provide a link between glutamate-mediated neurotoxicity, inflammation and oxidative stress. In addition, PQQ reduced the up-regulated expression of p-Akt by D-gal and maintained the activity of GSK-3ß, resulting in a down-regulation of p-Tau level in hippocampus. PQQ modulated memory ability partly via Akt/GSK-3ß pathway.

Regulation of the endoplasmic reticulum stress response and neuroprotective effects of acupuncture on brain injury caused by heroin addiction.

OBJECTIVES: To evaluate regulation of the endoplasmic reticulum stress (ERS) response by acupuncture and to investigate its neuroprotective effect on brain injury caused by heroin addiction. METHODS: A total of 48 male Sprague-Dawley rats were randomly divided into a healthy control group (Control), an untreated heroin exposed group (Heroin) and a heroin exposed group receiving electroacupuncture (EA) treatment at GV14 and GV20 (Heroin+acupuncture) with n=16 rats per group. A rat model of heroin addiction was established by intramuscular injection of incremental doses of heroin for 8 consecutive days. A rat model of heroin relapse was established according to the exposure (addiction) → detoxification method. Apoptotic changes in nerve cells in the hippocampus and ventral tegmental area (VTA) were evaluated in each group of rats using terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) assay. PERK, eIF2a, CHOP, IRE1 and JNK gene expression and protein expression were measured using quantitative real-time PCR (RT-qPCR) assay and immunohistochemical assay, respectively. RESULTS: The total number of positive nerve cells in the hippocampus and VTA was significantly lower in the Heroin+acupuncture group than in the Heroin group (p<0.01). Compared with the Heroin group, mRNA and protein expression of PERK, eIF2a, CHOP, IRE1 and JNK in the hippocampus and VTA were significantly downregulated in the Heroin+acupuncture group (p<0.05). CONCLUSION: The acupuncture-regulated ERS response appears to mediate the neuroprotective effect of acupuncture in heroin-addicted rats with brain injury. Inhibition of CHOP and JNK upregulation and reduction of nerve cell apoptosis may be the main mechanisms underlying the effects of acupuncture on heroin addiction-induced brain injury.

Acupuncture regulates the unfolded protein response and inhibits apoptosis in a rat model of heroin relapse.

OBJECT: To explore the unfolded protein response (UPR) in the hippocampus of rats undergoing heroin relapse and the mechanisms underlying the acupuncture-mediated inhibition of brain damage caused by heroin relapse. METHODS: 60 Sprague-Dawley rats (30 females and 30 males) were randomly divided into four groups: Control group, Heroin group, Heroin+acupuncture group, and Heroin+methadone group (n=15 each). In the latter three groups, a model of heroin addiction was established by successive increments of intramuscular heroin injections for 8 days, according to the exposure (addiction)→detoxification method. A UPR RT2 Profiler PCR array was used to screen for differentially expressed genes in the hippocampus. Apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) staining. The protein expression levels of the following three differentially expressed genes were detected by Western blot to validate the results of the PCR array: heat shock protein (HSP)70, HSP105, and valosin-containing protein (Vcp). RESULTS: The UPR RT2 Profiler PCR Array detection results indicated that acupuncture increased the expression levels of the molecular chaperones HSP70, HSP105, and Vcp. The degree of neuronal apoptosis in the hippocampus of rats in the Heroin+acupuncture and Heroin+methadone groups was significantly reduced compared with the untreated Heroin group (p<0.01). Protein expression of HSP70, HSP105, and Vcp in the Heroin+acupuncture and Heroin+methadone groups was significantly higher than the Heroin group (p<0.01). CONCLUSIONS: The positive effects of acupuncture on brain damage caused by heroin may be closely related to up-regulation of HSP70, HSP105, and Vcp, and reduced apoptosis.

Acupuncture at Baihui and Dazhui reduces brain cell apoptosis in heroin readdicts.

Acupuncture at Baihui (GV20) and Dazhui (GV14) reduces neuronal loss and attenuates ultrastructural damage in cerebral ischemic rats. However, whether acupuncture can treat addiction and prevent readdiction through changes to brain cell ultrastructure remains unknown. In this study, cell apoptosis was observed in the hippocampus and frontal lobe of heroin readdicted rats by electron microscopy. Immunohistochemical staining displayed a reduction in Bcl-2 expression and an increase in Bax expression in the hippocampus and frontal lobe. After rats were given acupuncture at Baihui and Dazhui, the pathological damage in the hippocampus and frontal lobe was significantly reduced, Bcl-2 expression was upregulated and Bax expression was downregulated. Acupuncture exerted a similar effect with methadone, a commonly used drug for clinical treatment of drug addiction. Experimental findings suggest that acupuncture at Dazhui and Baihui can prevent brain cell apoptosis in heroin readdicted rats.

Normalization of ventral tegmental area structure following acupuncture in a rat model of heroin relapse.

Drugs can cause obvious damage to the brain. To verify the relationship between acupuncture, neurotrophic factor expression and brain cell structural changes, this study established a rat model of heroin relapse using intramuscular injection of increasing amounts of heroin. During the detoxification period, rat models received acupuncture at Baihui (DU20) and Dazhui (DU14). Electron microscopy demonstrated that the structure of the ventral tegmental area in heroin relapse rats gradually became normalized after acupuncture treatment. Immunohistochemical staining exhibited that the expression of brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor increased in the ventral tegmental area following acupuncture. Moreover, the effects were similar to that of methadone, a type of medicine called an opioid. Results suggested that acupuncture at Baihui and Dazhui protected brain neurons against injury in rats with heroin relapse by promoting brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor expression.

[Survey of studies on drug abstinence with acupuncture in recent 10 years].

The effect of acupuncture on substance withdrawl syndromes and craving relapse prevention of the recent 10 years were reviewed as well as its mechanism. The therapeutic effect and the possible mechanism were analyzed on the basis. From the three aspects of anti protracted abstinence symptoms, craving relapse prevention and mechanism of acupuncture, the development tendency and the prospect of application on drug withdrawl with acupuncture were expected. And it is proposed that clinical observation of acupuncture intervention on craving should be developed, the mechanism of acupuncture impact on cognitive behavior, blocking study and memory processing related to drug addiction should be explored, so as to further give play to the advantages of acupuncture on anti-drug addiction.

[Influence of betulinic acid on proliferation, migration, cell cycle and apoptosis of pancreatic cancer cells].

OBJECTIVE: To investigate the effect of betulinic acid (BA) on the proliferation, migration, apoptosis and cell cycle of pancreatic cancer cells (BxPC-3) in vitro and elucidate the underlying. METHOD: The effect of BA on the proliferation of BxPC-3 was measured by using sulforhodamine B (SRB) assay. Migratory ability of BxPC3 cells were detected by wound healing assay, and the morphological change was observed with light microscope. The influence of BA on cell cycle of BxPC-3 cells was tested by flow cytometry (FCM). Apoptosis was analyzed by using Hochest33342-PI double staining. Western blot technologies were applied to detect the expression of Bcl-2 and Bax. RESULT: BA exhibited significant cell proliferation and migration inhibition, as well as its potency of inducing apoptosis in BxPC-3 cells in vitro in a dose-dependent manner. The IC50 value for 72 h was 16.54 mg x L(-1). Cell migration was significantly inhibited at 5 mg x L(-1) of BA. Cells treated with BA showed increased cell population in G0 phase, with decreased G2/M phase population. The expression of Bax and Bcl-2 was up and down-regulated respectively in BA-treated BxPC-3 cells in a dose-dependent manner. CONCLUSION: BA exerted potent effect on growth inhibition, G0 cell cycle arrest and induction of apoptosis in BxPC-3 cells in vitro, possibly associated with the down-regulation of Bcl-2 and up-regulation of Bax expression. The potent antitumor capacity of BA suggested that it could be a promising new anticancer agent in human pancreatic cancer treatment.

[Influence of acupuncture and moxibustion on conditional position preference and prefrontal cortical ultrastructure in heroin re-addicted rats].

OBJECTIVE: To observe the effect of acupuncture and moxibustion on the conditional position preference (CPP) and prefrontal cortical ultrastructure in heroin re-addicted rats. METHODS: Thirty-two Wistar rats were randomly divided into normal, model, medication and acu-moxibustion (acu-moxi) groups, with 8 cases in each. Re-addiction model was established by repeated intramuscular injection of heroin into the hindlimbs. Rats of medication group were treated with intragastric administration of Methadone during detoxification. For rats in acu-moxi group, acupuncture needle was inserted into "Baihui" (GV 20) and moxibustion treatment was used to bilateral "Shenshu" (BL 23) for 30 min during detoxification. Rats in normal group were given with intramuscular injection of normal saline during addiction. CPP tests were conducted once daily in a spatial place preference box for 8 days. On the 39th day of the experiment, the rats under anesthesia were killed for sampling the prefrontal cortex (PFC) tissue on an ice plate, then, the ultrastructure of the neurons was observed by using a transmission electron microscope. RESULTS: After modeling, the rats' staying duration in the dark-box was shortened obviously (P < 0. 1). After the treatment, the staying duration in dark-box in acu-moxi group was significantly longer than that in model and medication groups (P < 0.01). Compared with normal control group, electron-microscopic results indicated that in PFC tissues of model and medication groups, vacuoles and edema of cytoplasm at different degrees, enlargement of the rough endoplasmic reticulum (REPR), vacuoles or disappearance of mitochondria, reduction of ribosome in number, and widening of the nuclear intermembrance interstice were seen. While in acu-moxi group, the number of mitochondria and ribosome increased slightly, the mitochondrial cristae was clear, the number of REPR increased relatively but dilated slightly, and the intermembrance space was basically normal. CONCLUSION: Acu-moxibustion can improve heroin re-addicted rats' conditional position preference and has a protection effect on the cerebral cortical neurons. disappearance of mitochondria, reduction of ribosome in number, and widening of the nuclear intermembrance interstice were seen. While in acu-moxi group, the number of mitochondria and ribosome increased slightly, the mitochondrial cristae was clear, the number of REPR increased relatively but dilated slightly, and the intermembrance space was basically normal. CONCLUSION: Acu-moxibustion can improve heroin re-addicted rats' conditional position preference and has a protection effect on the cerebral cortical neurons.

[Effect of electroacupuncture on thymocyte apoptosis-related genes in morphine withdrawal rats].

OBJECTIVE: To explore the underlying mechanism of electroacupuncture (EA) in relieving morphine withdrawal syndrome in rats. METHODS: Forty SD rats were randomly divided into normal control group, model group 1, model group 2 and EA group. Morphine withdrawal syndrome model was established by muscular injection of morphine (5 mg/kg on the 1st day, progressively increasing everyday till 100 mg/kg on the 20th day) in the hind limbs. Then, rats of model group 1 were anesthetized (10% chloraldurat) to be killed on the 21st day, and those of model group 2 killed on the 27th day. EA (2/100 Hz, 2-4 mA) was applied to bilateral "Zusanli" (ST 36) for 30 mm, once a day for 7 days. The rat's thymus was removed (after anesthesia), cut into sections (4 pm) and stained with immunohistochemical method for displaying the expression of apoptotic promoters Bax, Fas, Fas Ligand (FasL) as well as anti-apoptotic peptide Bcl-2. RESULTS: Compared with normal group, Bcl-2 immunoreaction (IR)-positive cell number of model group 1 and group 2 decreased significantly while Sax, Fas and FasLIR-positive cell number and Bax/Bcl-2 in two model groups increased considerably (P < 0.01). In comparison with model group 2, Bcl-2 IR-positive cell number of model group 1 decreased significantly (P < 0.05), Bax, Fas and FasL IR-positive cell number and Bax/Bcl-2 of model group 1 were significantly higher (P < 0.01, fl. 05). After EA, in comparison with model group 2, Fas and FasL IR-positive cell number and Bax/Bcl-2 decreased significantly (P < 0.01, 0.05), and Bcl-2 IR-positive cell number increased markedly in EA group (P < 0.05); in comparison with model group 1, Bcl-2 IR-positive cell number increased significantly (P < 0.01), while Bax, Fas and FasL IR-positive cell number and Bax/Bcl-2 decreased evidently in EA group (P < 0.01). CONCLUSION: EA at "Zusanli" (ST 36) can inhibit morphine-induced downregulation of Bcl-2 and upregulation of Fas and FasL expression, which may contribute to its effect in resisting thymus apoptosis in morphine withdrawal rats.

[Effects of extract of Ginkgo biloba on intercellular adhesion molecule-1 and mRNA expression in rats with cerebral injury].

OBJECTIVE: To investigate the effects of Extract of Ginkgo biloba on ICAM-1 and mRNA expression in rats with cerebral injury, and discuss its protective mechanism. METHODS: The acute closed brain injury model was set up in rats according Feeney's method. Seventy-two rats were randomly divided into four groups. The levels of ICAM-1 expression were observed using immunohistochemistry and computerized imaging technique and the expression of mRNA were studied using RT-PCR techniques. RESULTS: ICAM-1 positive cells located in the transitional zone between the necrotic core and normal cortex. ICAM-1 protein and mRNA expression began to show 6 hours after cerebral injury, peaked at 24 hours. As compared with the model group, ICAM-1 and mRNA expression was significantly reduced in the group EGb (P < 0.01). CONCLUSION: EGb can markedly reduce the injury of nerve cell in the transitional zone, alleviate rat cerebral injury, and decrease ICAM-1 and mRNA expression and neutrophils infiltration. The protection may be related with its inhibition on ICAM-1 and mRNA expression.

[Effect of compound Salvia injection on blood coagulation in patients with traumatic cerebral infarction].

OBJECTIVE: To investigate the effect of compound Salvia injection (CSI) on blood coagulatory function in patients with traumatic cerebral infarction (TCI). METHODS: Sixty-four patients with TCI were randomly divided into two groups, 32 in each group. The treated group were treated with CSI plus conventional treatment of western medicine, and the control group treated with conventional treatment alone. Changes of symptoms, levels of plasma P-selectin (P-S), von Willebrand's factor (vWf) and D-dimer were observed with ELISA. RESULTS: The treated group was superior to the control group in Glasgow outcome scale (P < 0.01). Before treatment, the levels of plasma P-S, vWf and D-dimer in the TCI patients were higher than those in healthy people. After treatment, all the parameters lowered in both groups, but the effect of lowering was greater in the treated group than that in the control group. CONCLUSION: Blood coagulation disorder exists in patients with TCI, CSI could improve it, and might alleviate the cerebral damage to a certain extent.
