ABSTRACT

In this experiment, the PK/PD fitting model of Chuanxiong(Chuanxiong Rhizoma) in the treatment of rheumatoid arthritis was established in the form of acupoint combined with external application gel paste. Firstly, the rheumatoid arthritis model was induced by ovalbumin, and the articular fluid of rabbits was extracted by microdialysis. The pharmacokinetic process of Chuanxiong in rabbit articular fluid was analyzed by UPLC-MS/MS, and the pharmacokinetic model was established. The pharmacodynamic effects of Chuanxiong on inflammatory factors IL-1β, TNF-α, and IL-6 were analyzed by enzyme-linked immunosorbent assay(ELISA). The pharmacodynamic model was established, and the PK/PD model was obtained by fitting the data of pharmacokinetics and pharmacodynamics. The results of pharmacokinetics showed that the concentration of ligustrolide A in the articular cavity by drug administration on classical acupoint Zusanli(ST 36) was higher than that by Yanglingquan(GB 34), which reflected the advantage of typical acupoint, while ligustrazine concentration was higher after administration through Yanglingquan than through Zusanli, which was different from the traditional acupoint theory. The results of pharmacodynamics showed that the drug had lag effect. The PK/PD model was constructed by fitting the data. When IL-1β was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=115.28C_e/(3 316.72+C_e), E=108.73C_e/(2 993.47+C_e), and E=101.34C_e/(3 028.51+C_e). When TNF-α was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=68.31C_e/(3 285.16+C_e), E=59.27C_e/(2 919.86+C_e), and E=53.61C_e/(2 862.87+C_e). When IL-6 was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=59.92C_e/(3 461.17+C_e), E=58.34C_e/(2 723.51+C_e), and E=49.17C_e/(2 862.76+C_e). The parameters showed that there were significant differences in E_(max), EC_(e50) and k_(eo). The analysis of data found that the PK/PD fitting effect of Zusanli, a typical acupoint, was the best, which proved that it was still the best site for drug administration. To sum up, it shows that there may be bidirectional selectivity between drugs and acupoints.

ABSTRACT

Abstract Objective To compare the analgesic effect of intercostal nerve block (INB) with ropivacaine when given preventively or at the end of the operation in patients undergoing video-assisted thoracic surgery (VATS). Methods A total of 50 patients undergoing VATS were randomly divided into two groups. The patients in the preventive analgesia group (PR group) were given INB with ropivacaine before the intrathoracic manipulation combined with patient-controlled analgesia (PCA). The patients in the post-procedural block group (PO group) were administered INB with ropivacaine at the end of the operation combined with PCA. To evaluate the analgesic effect, postoperative pain was assessed with the visual analogue scale (VAS) at rest and Prince Henry Pain Scale (PHPS) scale at 6, 12, 24, 48, and 72 hours after surgery. Results At 6 h and 12 h post-surgery, the VAS at rest and PHPS scores in the PR group were significantly lower than those in the PO group. There were no significant differences in pain scores between two groups at 24, 48, and 72 hours post-surgery. Conclusion In patients undergoing VATS, preventive INB with ropivacaine provided a significantly better analgesic effect in the early postoperative period (at least through 12 h post-surgery) than did INB given at the end of surgery.

ABSTRACT

OBJECTIVE@#Cardiovascular diseases are associated with an increased risk of depression, but it remains unclear whether treatment with cardiovascular agents decreases or increases this risk. The effects of drugs on individual usage are also often unknown. This review aimed to examine the correlation between depression and common cardiovascular drugs, develop more potent interventions for depression in cardiovascular patients, and further research on the bio-behavioural mechanisms linking cardiovascular drugs to depression.@*DATA SOURCES@#The data in this review were obtained from articles included in PubMed, EMBASE, and Web of Science.@*STUDY SELECTION@#Clinical trials, observational studies, review literature, and guidelines about depression and cardiovascular drugs were selected for the article.@*RESULTS@#We systematically investigated whether the seven most used cardiovascular drugs were associated with altered risk of incident depression in this literature review. Statins have been proven to have antidepressant effects. Some studies believe angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blocker (ARB) can exert an antidepressant influence by acting on the renin-angiotensin system, but further clinical trials are needed to confirm this. Beta-blockers have previously been associated with depression, but the current study found no significant association between beta blockers and the risk of depression. Aspirin may have antidepressant effects by suppressing the immune response, but its role as an antidepressant remains controversial. calcium channel blockers (CCBs) can regulate nerve signal transduction by adjusting calcium channels, but whether this effect is beneficial or harmful to depression remains unclear. Finally, some cases have reported that nitrates and diuretics are associated with depression, but the current clinical evidence is insufficient.@*CONCLUSIONS@#Statins have been proven to have antidepressant effect, and the antidepressant effects of ACEIs/ARB and aspirin are still controversial. CCBs are associated with depression, but it is unclear whether it is beneficial or harmful. No association has been found with β-blockers, diuretics, and nitrates.

ABSTRACT

OBJECTIVE: Nuclear factor‑κB (NF‑κB) activity is crucial for survival and proliferation of many kinds of malignancies, including gastric cancer (GC). The receptor for activated protein kinase C 1 (RACK1) is known to regulate tumor development, whereas the underlined mechanism has not been described clearly. MATERIALS AND METHODS: We analyzed expression of RACK1 in paired human GC samples by both real‑time polymerase chain reaction (PCR) and western blot. Effects of RACK inhibition with small interfering RNA or its overexpression in cultured GC cell lines were evaluated in cell viabilities. NF‑κB signaling was investigated using luciferase reporter assay and real‑time PCR. RESULTS: RACK1 was significantly decreased in GC samples. Knockdown of RACK elevated GC cell viabilities, whereas overexpression of RACK1 suppressed tumorigenesis of GC cells. Importantly, NF‑κB signaling was enhanced after RACK1 expression was inhibited, suggesting the negative regulation of the pro‑oncogenic NF‑κB activity by RACK1 might contribute to its tumor suppressor role in GC cells. CONCLUSION: Our results support that RACK1 suppresses gastric tumor progression through the NF‑κB signaling pathway.

ABSTRACT

The study is aimed to explore the molecular mechanism of the treatment of apocynin in dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) mice. 5% DSS was used to mimic the UC model, and 2% apocynin was applied to treat the UC mice. HE staining was used for histopathological evaluation. Chemiluminescence technique was used to measure reactive oxygen species (ROS) production, and the rate of consumption of NADPH inhibited by DPI was detected to determine the NADPH oxidases (NOXs) activity. Western blot was applied to identify the level of p38MAPK phosphorylation, Griess reaction assay to analyze NO production, immunoenzymatic method to determine prostaglandin E2 (PGE2) production, real time RT-PCR and Western blot to identify the expression of iNOS and COX2, and enzyme linked immunosorbent assay to detect inflammatory cytokines TNF-α, IL-6, IFN-γ, IL-1β. Rat neutrophils were separated, and then ROS production, NOXs activity, NO and PGE2 production, NOX1 and p-p38MAPK expression were detected. Compared with the UC group, apocynin decreased ROS over-production and NOXs activity (P < 0.01), reduced p38MAPK phosphorylation, inhibited NO, PGE2 and cytokines production (P < 0.01). Apocynin also decreased NOXs activity and ROS over-production (P < 0.01), inhibited p38MAPK phosphorylation and NOX1 expression, and reduced NO and PGE2 production (P < 0.01) in separated neutrophils from UC mice. Therefore, apocynin could relieve inflammation in DSS-induced UC mice through inhibiting NOXs-ROS-p38MAPK signal pathway, and neutrophils play an important role.

ABSTRACT

Hypercoagulable state and thrombosis are major lethal causes of ulcerate colitis (UC). The aim of the present study is to explore the change and role of protein C (PC) system in UC thrombosis. 4% dextran sulfate sodium (DSS) was used to induce the UC model, and the body weight, the length of colon, and the weight of spleen were measured after intake of DSS as drinking water for 1 week. The macroscore and microscore were examined. The quantity of macrophage in colon smooth muscle was observed by immunofluorescence, and TNF-α and IL-6 levels in plasma were evaluated by ELISA. Intravital microscopy was applied to observe colonic mucosal microvascular circulation, activities of PC and protein S (PS) were determined by immunoturbidimetry, endothelial cell protein C receptor (EPCR) and thrombomodulin (TM) expressions were detected by immunohistochemistry. In vitro, TNF-α and IL-6 levels were tested in supernatant of macrophage separated from colonic tissue. After stimulation of mouse colonic mucosa microvascular endothelial cells by TNF-α and IL-6 respectively, the activities of PC, PS, activated protein C (APC) were evaluated, and the expressions of EPCR and TM were detected by Western blotting. The results revealed that compared with control, the DSS mouse showed weight loss (P < 0.05), a shortened colon (P < 0.05), and swelled spleen (P < 0.05), accompanied by higher histological score (P < 0.05), as well as infiltration of macrophages, elevated TNF-α and IL-6 levels in plasma (P < 0.01). The intravital microscopy results revealed that compared with control, DSS mice showed significantly enhanced adhesion of leukocytes and colonic mucosal microvascular endothelial cells (P < 0.01), meanwhile, decreased activity of PC and PS in plasma (P < 0.01 or P < 0.05), and down-regulated expression of EPCR (P < 0.01). The degree of inflammation was negatively correlated with the PC activity. In vitro, TNF-α and IL-6 levels were increased in the supernatant of macrophages from DSS mice colonic tissue (P < 0.05), and after incubation of TNF-α or IL-6 with colonic mucosal microvascular endothelial cells, the APC activity was decreased (P < 0.05 or P < 0.01), and expression of EPCR was down regulated (P < 0.05). These results suggest that PC system is inhibited in UC mouse. Presumably, the mechanism may be due to the secretion of cytokines from macrophages and subsequential influence on the function of endothelia cells. Furthermore, enhancement of PC system activity may serve as a new strategy for the treatment of UC.

ABSTRACT

The aim of the present study was to explore the role of orphan G protein-coupled receptor 55 (GPR55) in diabetic gastroparesis (DG). Streptozotocin (STZ) was used to mimic the DG model, and the body weight and blood glucose concentration were tested 4 weeks after STZ injection (i.p.). Electrogastrogram and phenolsulfonphthalein test were used for detecting gastric emptying. Motilin (MTL), gastrin (GAS), vasoactive intestinal peptide (VIP), and somatostatin (SS) levels in plasma were determined using radioimmunology. Real-time PCR and Western blot were applied to identify the expression of GPR55 in gastric tissue, and immunohistochemistry was used to detect the distribution. The effect of lysophosphatidylinositol (LPI), an agonist of GPR55, was observed. STZ mice showed increased blood glucose concentration, lower body weight, decreased amplitude of slow wave, and delayed gastric emptying. LPI antagonized these effects of STZ. Compared to the control group, STZ caused significant decreases of MTL and GAS levels (P < 0.01), as well as increases of SS and VIP levels (P < 0.01). The changes of these hormones induced by STZ were counteracted when using LPI. GPR55 located in mice stomach, and it was up-regulated in DG. Although LPI showed no effects on the distribution and expression of GPR55 in normal mice, it could inhibit STZ-induced GPR55 up-regulation. These results suggest GPR55 is involved in the regulation of gastric movement of DG, and may serve as a new target of DG treatment. LPI, an agonist of GPR55, can protect against STZ-induced DG, and the mechanism may involve the change of GPR55 expression and modification of gastrointestinal movement regulating hormones.

ABSTRACT

High-altitude hypoxia can induce physiological dysfunction and mountain sickness, but the underlying mechanism is not fully understood. Corticotrophin-releasing factor (CRF) and CRF type-i receptors (CRFR1) are members of the CRF family and the essential controllers of the physiological activity of the hypothalamo-pituitary-adrenal (HPA) axis and modulators of endocrine and behavioral activity in response to various stressors. We have previously found that high-altitude hypoxia induces disorders of the brain-endocrine-immune network through activation of CRF and CRFR1 in the brain and periphery that include activation of the HPA axis in a time- and dose-dependent manner, impaired or improved learning and memory, and anxiety-like behavioral change. Meanwhile, hypoxia induces dysfunctions of the hypothalamo-pituitary-endocrine and immune systems, including suppression of growth and development, as well as inhibition of reproductive, metabolic and immune functions. In contrast, the small mammals that live on the Qinghai-Tibet Plateau alpine meadow display low responsiveness to extreme high-altitude-hypoxia challenge, suggesting well-acclimatized genes and a physiological strategy that developed during evolution through interactions between the genes and environment. All the findings provide evidence for understanding the neuroendocrine mechanisms of hypoxia-induced physiological dysfunction. This review extends these findings.

ABSTRACT

<p><b>OBJECTIVE</b>To screen childhood ALL related microRNAs (miRNAs), analyze association of miRNAs expression profiles with prognosis and relapse in childhood acute lymphoblastic leukemia (ALL) and explore new indicator for predicting relapse and prognosis.</p><p><b>METHODS</b>miRNAs expression profile was analyzed by gene chip in 49 newly diagnosed childhood ALL and 12 primary immune thrombocytopenia (ITP) cases (as control group). Abnormal expression of miRNAs was verified by qRT-PCR. The correlation of miRNAs expression pattern with indicators predicting early prednisone response and relapse within a year was analyzed.</p><p><b>RESULTS</b>Specific expression of miRNAs profiles associated with prednisone response and early relapse in childhood ALL was identified. Eight miRNAs (miR-18a, miR-532, miR-218, miR-625, miR-193a, miR-638, miR-550 and miR-633) could distinguish prednisone sensitive from insensitive. The early relapse of newly diagnosed patients with either high-risk or non-high-risk clinical types had some characteristics of abnormal expression of miRNAs, including miR-7, miR-216 and let-7i upregulated, while miR-486, miR-191, miR-150, miR-487 and miR-342 downregulated.</p><p><b>CONCLUSIONS</b>The initial screening reveals miRNAs differentially expressed from normal in ALL suggesting the potential roles of them in leukemogenesis. MiRNAs expression signatures may be useful for predicting prognosis and relapse in childhood ALL and directing personalized treatment.</p>

ABSTRACT

Objective To explore the effects of gap junctional(GJ)proteins in pathogenesis of cerebral schistosomiasis, through observing the expression of gap junctional proteins Cx37 mRNA in cultured cerebral arterial endothelium incubated with soluble eggs antigen(SEA). MethodsCerebral artery endothelial cells of rabbits were incubated with SEA, and the experiments were divided into control group and SEA 1 - 5 groups (SEA concentrations were 10.0% ,5.0% ,3.3% ,2.5%,2.0%, respectively), reverse transcription polymerase chain reaction (RT-PCR) and Western blotting were used to examine the expression of Cx37 mRNA and protein in cerebral artery endothelial cells of rabbits, respectively. Results Cx37 mRNA levels of control and SEA 1 - 5 groups were 0.239 ± 0.037, 0.260 ± 0.043, 0.218 ± 0.310, 0.647 ± 0.040, 0.419 ± 0.036, and 0.513 ± 0.038, respectively;SEA 3 - 5 groups were higher than control group of mRNA levels(all P< 0.05). Cx37 protein levels of control and SEA 1 - 5 group were 0.401 ± 0.045, 0.485 ± 0.048, 0.749 ± 0.052, 1.119 ± 0.063, 1.015 ± 0.057 and 0.605 ±0.047, respectively, of which SEA 2 - 5 groups were higher than control group(all P < 0.05). ConclusionsExpression levels of Cx37 mRNA and protein in cultured cerebral artery endothelial cells incubated with SEA are higher than those of control cerebral artery endothelial cells, which suggests that the gap junction proteins may play an important role in pathogenesis of cerebral schistosomiasis through SEA and its secretion in infiltration of brain tissue and deposition in the cerebral arteries.

ABSTRACT

<p><b>OBJECTIVE</b>Recent studies have suggested that there is a close relation between microRNA and acute leukemia (AL). The aim of this study was to investigate and better understand the classification and diagnosis of AL as well as pathogenesis and prognosis of this disease.</p><p><b>METHODS</b>A total of 93 children with AL and and 12 cases of idiopathic thrombocytopenic purpura (as control group) were enrolled in this study. Microarray chip analysis of their bone marrow samples was conducted to evaluate the microRNA profiles. Quantitative real-time PCR was performed for validating the abnormal expression of microRNA.</p><p><b>RESULTS</b>The microRNA expression profiles were different between acute granulocytic leukemia and acute lymphoblastic leukemia and also between the three subtypes (M1, M2 and M3) of acute granulocytic leukemia according to FAB classification based on leukemic cell differentiation. These three subtypes of leukemia could be identified by unsupervised hierarchical cluster analysis of microRNA expression and had specific up-regulation of miR-335, miR-126 and miR-125b, respectively. However, in the M2 and M3 subtypes with positive AML1-ETO and PML-RARα, respectively, which have a better prognosis, the expressions of miR-126 and miR-125b were significantly higher than those with negative AML1-ETO and PML-RARα. Further more, miR-335 and miR-146 were up-regulated in acute granulocytic leukemia observed in this study, which are different from those reported for adult patients.</p><p><b>CONCLUSIONS</b>microRNA cascade may serve as new biomarkers for the classification and diagnosis of pediatric AL. It is also suggested that there might be different pathogenesis and prognosis between AL types related to specific expression and regulation of microRNA.</p>

Besides routine therapy, Chonggu (EX-HN 27) and Lianquan (CV 23) were selected in the Chonggu (EX-HN 27) deep insertion group and the Chonggu (EX-HN 27) shallow insertion group; the needles were inserted for 60-75 mm and 30 mm respectively and the electroacupuncture was applied in both groups; in traditional acupuncture group, Fengchi (GB 20), Yifeng (TE 17), Wangu (GB 12) and Lianquan (CV 23), etc. were selected. The needles were retained for 30 min, twice a day and 30 treatments totally in 3 groups. The clinical therapeutic effects were evaluated by Kubota's Water Drinking Test Scale, Standard Swallowing Function Scale and TCM Scale of Dysphagia After Stroke.</p><p><b>RESULTS</b>The total effective rate was 97.0% (96/99) in the Chonggu (EX-HN 27) deep insertion group, superior to that of 64.9% (61/94) in Chonggu (EX-HN 27) shallow insertion group and 70.0% (63/90) in traditional acupuncture group (both P < 0.05). Compared with the scores before and after treatment, significant differences were presented statistically in score reduction of TCM Scale in Chonggu (EX-HN 27) shallow insertion group (P < 0.01); the scores of Kubota's Water Drinking Test Scale, Standard Swallowing Function Scale and TCM Scale of Dysphagia After Stroke were obviously reduced in Chonggu (EX-HN 27) deep insertion group and traditional acupuncture group (all P < 0.01); compared with the scores between groups after treatment, the reduction of scores in Chonggu (EX-HN 27) deep insertion group was superior to those in Chonggu (EX-HN 27) shallow insertion group and traditional acupuncture group ( P < 0.05, P < 0.01) respectively.</p><p><b>CONCLUSION</b>Puncture at Chonggu (EX-HN 27) can improve the dysfunction of swallowing after stroke; it is safe and effective, and the needle should be inserted deeply.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To probe the effect and mechanism of the nuchal acupuncture and abdominal acupuncture for treatment of stroke patients with spastic hemiplegia.</p><p><b>METHODS</b>Sixty cases were randomly divided into an observation group and a control group, 30 cases in each group. Nuchal acupuncture and abdominal acupuncture treatment was used and Fengfu (GV 16), Fengchi (GB 20), Tianzhu (BL 10), Zhongwan (CV 12) and Guanyuan (CV 4) etc. were selected in observation group, routine acupuncture was applied on Binao (LI 14), Quchi (LI 11), Huantiao (GB 30) and Futu (ST 32) etc. in control group. The scale of Ashworth and score of Fugel-Meyer of the spastic lateral upper and lower limbs and the changes of the EMG F-wave in spastic upper limb of patients in two groups were observed before and after treatment.</p><p><b>RESULTS</b>The Ashworth scale and Fugel-Meyer score of the upper and lower limbs were obviously improved, the amplitude was decreased, the duration was shorten and the threshold of the EMG F-wave of the spastic upper limb was increased (all P < 0.01) in the observation group. The observation group was superior to the control group in Fugel-Meyer score of the upper and lower limbs of the patients the Ashworth scale of the lower limb, and the amplitude, duration and threshold of the EMG F-wave of the spastic upper limb (all P < 0.01). The total effective rate of 90.0% in observation group was superior to that of 50.0% in control group (P < 0.01).</p><p><b>CONCLUSION</b>The nuchal acupuncture and abdominal acupuncture treatment can decrease the muscle tension of the stroke patients with spastic hemiplegia.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the correlation of venous return disturbance (VRD), bone marrow edema (BME) and the amount of joint fluid with clinical symptoms in osteonecrosis of the femoral head (ONFH).</p><p><b>METHODS</b>Twenty patients (25 hips) with ONFH proved by pathology were parallelly examined by 1.5 T MR and medullograph.</p><p><b>RESULT</b>In total 25 hips VRD was observed in 16 hips with medullograph and 13 hips with the clinical symptoms (P <0.05). BME was found in 17 with MRI (P <0.01), and the was found in 15 hips with MRI (Spearman=0.949). VRD were found in 16 hydrarthrus.</p><p><b>CONCLUSION</b>ONFH patients with clinical symptoms have VRD, BME and the hydrarthrus. The medullograph is of value in monitoring the development of ONFH.</p>
