RESUMEN
Objective:To evaluate the effect of Qianyang Huoxue Ointment in the adjuvant treatment of patients with hypertension and blood-stasis yang hyperactivity.Methods:According to random number table method, 60 patients with hypertension of blood-stasis yang hyperactivity in The First Affiliated Hospital of University of Science and Technology of China were divided into two groups between January 2020 and June 2021, 30 in each group. The control group was given routine anti-hypertension therapy, while observation group was treated with Qianyang Huoxue Ointment on basis of control group. All patients were continuously treated for 28 d. Before and after treatment, TCM symptoms were scored. 24h ambulatory blood pressure were recorded. The blood pressure was measured before treatment and at 7, 14 and 28 d after treatment. Adverse events during treatment were recorded. Clinical efficacy and efficacy on TCM syndromes were evaluated.Results:The differences in total clinical response rate between observation group and control group were statistically significant [93.3% (28/30) vs. 70.0% (21/30), χ 2=5.46, P=0.020], and differences in total response rate of efficacy on TCM syndromes between observation group and control group were statistically significant [90.0% (27/30) vs. 66.7% (20/30), χ2=4.81, P=0.028]. After treatment, scores of TCM syndromes (dizziness, headache, burning sensation, insomnia, tinnitus, forgetfulness, soreness and weakness of waist and knees) and total score in observation group were significantly lower than those in the control group ( t=5.77, 7.02, 6.97, 6.31, 6.23, 7.49, 9.60, 8.16, P<0.01). At 7, 14 and 28 d after treatment, levels of systolic blood pressure and diastolic blood pressure in observation group were significantly lower than those in the control group ( F=99.18, 49.32, P<0.001). At 24 hour after treatment, levels of systolic blood pressure [(143.91±5.04)mmHg vs. (149.18±4.93)mmHg, t=4.09] and diastolic blood pressure [(92.35±2.98)mmHg vs. (95.66±2.97)mmHg, t=4.31] in observation group were significantly lower than those in the control group ( P<0.01). There were no significant adverse events between both groups. Conclusion:The application of Qianyang Huoxue Ointment on basis of routine western medicine can improve clinical symptoms, control blood pressure level and improve clinical efficacy in the patients with hypertension of blood-stasis yang hyperactivity.
RESUMEN
Objective To compare the effects of bilateral and non- bilateral frontal pneumocephalus on acute agitation after craniotomy for brain tumor. Methods The clinical data of 406 brain tumor patients who had underwent craniotomy in Maoming Traditional Chinese Medicine Hospital and Guangdong Provincial People′s Hospital from January 2014 to January 2019 were retrospectively analyzed. The patients were divided into bilateral frontal pneumocephalus group (92 cases) and unilateral frontal pneumocephalus group (314 cases) according to frontal pneumocephalus within 12 hours after operation. Within 24 hours after operation, the sedation-agitation scale (SAS) was evaluated, and SAS≥ 5 scores was defined as acute agitation. Results The incidence of postoperative acute agitation, rate of postoperative sedatives use and postoperative hospital stay in bilateral frontal pneumocephalus group were significantly higher than those in unilateral frontal pneumocephalus group: 23.9% (22/92) vs. 8.6% (27/314), 14.1% (13/92) vs. 3.5% (11/314) and (12.2 ± 2.6) d vs. (8.5 ± 1.6) d, and there were statistical differences (P＜0.01 or ＜0.05). Conclusions Brain tumor patients who had bilateral frontal pneumocephalus after craniotomy are more likely to develop acute agitation.

Objective To explore the risk factors of pulmonary artery hypertension (PAH) and the its relationship with T cell subsets to provide a foundation for the prevention and treatment of PAH.Methods 154 maintained hemodialysis (MHD) patients in our dialysis center were recruited according to the criterion and divided into two groups subsequently:PAH group (pulmonary artery systolic pressure,PASP ＞ 35 mmHg) and non-PAH group (PASP≤35 mmHg).The related clinical,biochemical and ultrasonic cardiogram data were collected and peripheral blood was acquired to detect the expressions of the surface antigen CD3,CD4,CD8 and CD69 with flow cytometry.Logistic regression analysis was used to find out the relationship between PAH and T cell subsets.Results There was no significant difference between 56 cases of PAH and 98 cases of non-PAH as regards gender,age,mean systolic and diastolic pressure,dialysis durations,morbidities of hypertension and diabetes,smoking rate,and left ventricular diameter.Compared with the non-PAH group,the PAH group demonstrated a lower percent of CD8 T cells and CD8 CD69 T cells,but a much higher left atrial diameter (LAD),Interventricular septum thickness,left ventricular posterior wall thickness,and NT-proBNP.The percentage of T cells,CD4 T cells and CD4 CD69 T cells showed no difference between the two groups.Multivariate analysis confirmed that PAH was negatively independently associated with the percentage of CD8 T cells and CD8CD69 T cells.Conclusions The decreased percentage of CD8 T cells and CD8CD69 T cells in the peripheral blood is a risk factor of PAH in maintained hemodialysis patients,and CD8 T cells may play an important role in the genesis of PAH.

Objective To explore the effect of high voltage alternating electric field therapy on fracture healing in rats. Methods An animal model of cortical bone defect was successfully established in the unilateral proximal tibia of 41 rats.They were then randomized into an experimental group (21 rats) and a control group (20 rats).The animals in the experimentsl group were given high voltage alternating electric field therapy for 30 minutes daily,while those in the control group only had sham exposure to the high voltage alternating electric field therapy.Rats in each group were sacrificed at days 7,14,21 and 28 post-operation.After blood collection,the operated tibias of the rats were resected with muscle and other soft tissue removed.Bone mineral density (BMD) of the callus at the fracture point was measured using dual energy X-ray absorptiometry (DEXA).The calluses were then cut down and fixed,decalcificated and sliced for histological observation.At the same time serum osteocalcin ( OC ) and bone alkaline phosphatase (RAP) were also detected by ABC-ELISA. Results The BMD examination showed that callus BMD in the experimental group was significantly higher than in the control group at days 14 and 28.Serum OC and RAP in the experimental group were also higher at days 14 day 21,and OC was still significantly higher in the experimental group at day 28.Histological examination showed that in the early stages of bone healing hematoma absorption and organization appeared earlier in the experimental group than in the control group,with remarkable osteoblast and chondroblast proliferation.While at the later stage,bone trabeculas connection and mineralization also appeared earlier in the experimental group than in the control group. Conclusions High voltage alternating electric field therapy may promote fracture healing by accelerating hematoma absorption and organization,elevating osteoblast proliferation and differentiation as well as promoting extracellular matrix secretion and mineralization.The underlying therapeutic mechanism might be related to the increased expression of OC and RAP caused by exposure to the high voltage alternating electric field.
RESUMEN
ObjectiveTo evaluate the effect of aminoguanidine on expression of inducible nitric oxide synthase (iNOS) in neurons in the small intestinal nerve plexus of starved rats.MethodsNinety male SD rats weighing 230-270 g were randomly divided into 3 groups:group normal control (group C,n =10) ; group starvation (group S,n=40) and group starvation + aminoguanidine (group A,n =40).The animals were allowed free access to water but no food during starvation in S and A groups.In group A the animals were given aminoguanidine 150 mg·kg-1 ·d-1 intraperitoneally during starvation.Ten animals were sacrificed at 3,5,7 and 9 d of starvation respectively and intestine specimens were taken for determination of ratio of intestinal transit using dextran blue-2000 as indicator.Then the specimens of intestinal myenteric nerve plexus of ileum were collected and stained by histochemistry with nicotinamide-adenine dinucleotide phosphate-d for determination of iNOS expression.ResultsStarvation significantly reduced the small intestinal transit and increased iNOS expression in neurons in the myenteric nerve plexus of small intestine in proportion to days of starvation in group S compared with group C.Intraperitoneal aminoguanidine significantly attenuated the starvation-induced changes in intestinal transit and iNOS expression.ConclusionAminoguanidine can attenuate the up-regulation of the expression of iNOS in neurons in the myenteric nerve plexus of small intestine induced by starvation and is helpful in promoting the intestinal transit in starved rats.
