ObjectiveTo investigate the clinical efficacy of combined traditional Chinese and western medicine for treatment of patients with deep venous thrombosis(DVT)in lower extremity.Methods A retrospective study was conducted. Forty patients with DVT admitted into Mindong Hospital Affiliated to Fujian Medical University were randomly divided into control and treatment groups, 20 cases in each group. Conventional therapy was given in both groups. The patients in control group were hypodermically injected with low molecular heparin 3.075 kU, and orally took warfarin sodium; the former injection was terminated on the 3rd day, and afterwards warfarin was solely administered. On the basis of the treatment in the control group, the patients in treatment group were additionally treated with Huoxue Tongmai decoction(ingredients: peach kernel 15 g, red paeonia 15 g, honeysuckle flower 15 g, rhizoma alismatis 12 g, semen coicis 30 g, semen plantaginis 9 g, suberect spatholobus stem 12 g, radix scrophulariae 9 g, pawpaw 12 g, radix achyranthis bidentatae 12 g), the formula could be modified in accordance with patients' symptoms and signs, and Jiangjun powder was applied at the lesion externally(ingredients of the powder: rhubarb 250 g, mirabilite 200 g, flour 100 g, vinegar 500 g were mixed to form a smooth paste), once a day, 30 days constituting a therapeutic course and totally 2 courses being taken. The perimeter of the affected limb, visual analogy score(VAS), revascularization rate, curative effect and adverse reaction were observed before and after treatment and compared between the two groups.Results The total effective rate in treatment group was higher than that in control group〔90.0%(18/20) vs. 70.0%(14/20),P<0.05〕. After treatment, the perimeter of the affected limb in both groups was significantly smaller than that before treatment, the decrease in treatment group being more marked〔the upper leg(cm):46.21±4.80 vs. 53.18±4.45, the lower leg(cm): 32.57±4.26 vs. 36.21±5.01, bothP<0.05〕. TheVAS scores were significantly decreased in both groups after treatment for 1 month, they reached the valley values after treatment for 2 months, the degree of descent being more significant in the treatment group(2.24±0.58 vs. 3.36±0.61,P<0.01). The revascularization rate of the treatment group after treatment was higher than that of the control group〔85.0%(17/20) vs. 70.0%(14/20),P<0.05〕.ConclusionThe combined treatment of traditional Chinese and western medicine was obviously superior to the sole western medicine for treatment of patients with DVT.

UPLC-MS-MS system was used for the identification of arbidol metabolites in the rat feces, urine and plasma samples. The system was so powerful a way with high ability of separation and analysis, based on both chromatography and mass properties. The isotope of Br was also a good indicator for metabolites finding. There were altogether 9 metabolites detected and identified, including 2 phase I biotransformation products and 7 phase II ones. It is concluded that arbidol mainly undergo metabolic reactions such as N-demethylation, S-oxidation, glucuronidation and sulfation in rats.

BACKGROUND:Hand-foot-mouth disease has become a major public health issue in children in China. In the present prospective study we investigated the clinical characteristics and emergency management of children with severe encephalitis associated with NPE caused by enterovirus 71. METHODS:The study was conducted in 2 pediatric intensive care units (PICUs) over a 2-month period. Clinical records were reviewed of critically ill children with severe encephalitis associated with NPE caused by EV71 who were admitted to PICUs during the period of May to June 2008 in Fuyang. RESULTS:We reviewed the complete records of 36 children, of whom 23 (63.9％) were male and 13 (36.1％) female. Their age ranged from 4 to 48 months, with an average of 15.8 months. Al children except one were under 3 years of age. The overal mortality in these children was 19.4％. The average duration of critical life threatening signs and symptoms was 2.1 days (12 hours-5 days). Nervous system diseases included brainstem encephalitis in 27 children (75％), brainstem encephalitis associated with myelitis in 6 children (16.7％), and general encephalitis in 3 chidren (8.3％), respectively. In 12 patients of NPE (33.3％) pink or bloody bubble sputum and asymmetric pulmonary edema or hemorrhage was the primary manifestation but no typical exanthema was observed. Five children died of acute onset of NPE and / or pulmonary hemorrhage with rapid progression of cardiopulmonary failure within hours after admission. Therapeutic management consisted of mechanical ventilation and administration of mannitol, methylprednisolone, intravenous immunoglobulin (IVIG) and vasoactive drugs, associated with the need of fluid volume resuscitation in 9 (25％) of the 36 children. CONCLUSIONS:In children less than 3 years of age found to be affected by severe EV71 encephalitis associated with NPE, one fifth may die. The major organ systems infected by severe EV71 include the central nervous system, the respiratory system, and the cardiovascular system. Early diagnosis and evaluation, respiratory support, treatment of intracranial hypertension, and mainttenance of function of the cardiovascular system are the most important therapeutic measures.

Objective:To explore the expression of microRNA-4695-5p in the serum of colorectal cancer patients and its effect on the proliferation and invasion of colorectal cancer CACO-2 cells.Methods:A total of 43 serum samples of colorectal cancer patients who were admitted to the Department of Gastrointestinal Surgery, Luoyang Central Hospital Affiliated to Zhengzhou University from March 2018 to November 2021 were selected, and serum samples of 43 healthy people who underwent outpatient physical examination were used as controls. Real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the relative expression levels in the serum of colorectal cancer patients and those of healthy individuals. The miR-4695-5p overexpression plasmid or the negative control plasmid were transfected into CACO-2 cells, namely the miR-4695-5p group and the control group, and the transfection efficiency was verified by qRT-PCR. CCK8 method and Transwell experiment were used to detect the effect of overexpression of miR-4695-5p on the proliferation and invasion of CACO-2 cells. The dual luciferase reporter gene experiment was used to verify the targeted binding relationship between miR-4695-5p and Ras-related C3 botulinum toxin substrate 1 (RAC1). qRT-PCR and Western blot were used to detect the effect of overexpression of miR-4695-5p on the expression of RAC1 gene and Wnt/β-Catenin signaling pathway protein.The software of SPSS28.0 was used to conduct data analysis. The measurement data of normal distribution were espressed by Mean±SD. The t-test was used to compare the means between two groups, and the one-way analysis of variance was used to compare the means of multiple groups. Results:The expression level of miR-4695-5p in the serum of patients with colorectal cancer was significantly lower than that of healthy individuals ( P<0.01). The relative expression levels of miR-4695-5p in the control group and miR-4695-5p group were 1.09 ± 0.65 and 8.83±2.03, respectively. The expression level of miR-4695-5p in CACO-2 cells in the miR-4695-5p group was 8.10 times that of the control group, and CACO-2 cells overexpressing miR-4695-5p were successfully constructed ( P<0.01). Compared with the control group, the proliferation ability of CACO-2 cells in the miR-4695-5p group was significantly reduced ( P<0.05), and the invasion ability of CACO-2 cells was significantly reduced ( P<0.01). Bioinformatics tools and dual luciferase reporter gene experiments confirmed that miR-4695-5p can target and bind RAC1 ( P<0.01). Compared with the control group, the expression of RAC1 gene in the miR-4695-5p group was significantly decreased ( P<0.01), and the expression of Wnt/β-Catenin signaling pathway proteins Wnt3a, β-catenin, and c-MYC decreased significantly. Conclusions:miR-4695-5p is lowly expressed in the serum of colorectal cancer patients. miR-4695-5p inhibits the proliferation and invasion of colorectal cancer CACO-2 cells by targeting the inhibition of RAC1 gene expression and down-regulating the activity of the Wnt/β-Catenin signaling pathway.

Objective To measure the concentration of intracellular free Ca2+ ([Ca2+]i) in neuron-like cells resulted from rat bone mesenchymal stem cell (BMSCs) differentiation induced by salvia miltiorrhiza injection and provide some theoretical basis for the BMSCs transplantation. Methods The rat BMSCs were separated from rat bone marrow and cultured in vitro. After induced by basic fibroblast growth factor and 10mL/L salvia miltiorrhiza injection, the cells were identified with immunofluorescence staining against NeuN. The same procedure was performed on primarily cultured hippocampal neurons. Then, the [Ca2+]i of the differentiated neuron-like cells was determined and compared with primarily cultured hippocampal neurons. Results The BMSCs after induced by basic fibroblast growth factor and salvia miltiorrhiza injection expressed neuronal phenotypes similar to the cell appearance of neurons with NeuN. The average fluorescence intensity of the neuron-like cells derived from BMSCs was 984.75±79.51, while the average fluorescence intensity of the primarily cultured hippocampal neurons was 769.42±60.93. No significant difference was found between them (P>0.05). Conclusion The neuron-like cells from rat BMSCs differentiation induced by salvia miltiorrhiza injection possess certain neuronal properties.

Objective To explore the application of modified CT imaging scale in the assessment of prognosis of comatose patients with severe traumatic brain injury. Methods Retrospective analysis was performed on the clinical data of 90 comatose patients with severe traumatic brain injury; according to the prognosis,they were divided into conscious group (n=47) and coma group (n=43).The modified CT imaging scale was used to analyze the relationship between these CT imaging data and prognosis,and the relationship between these CT imaging data and severity of illness. Results The scores of CT imaging scale in comatose patients were significantly higher than those in conscious patients (P＜0.05). Patients with 3-5 scores in GCS enjoyed higher scores of CT imaging scale as compared with those with 6-8 scores (P＜0.05).The scores of modified CT imaging scale and the GCS scores in these 90 patients showed negative correlation (Spearman's correlation coefficient:r=-0.79,P=0.000). Conclusion The modified CT imaging scale is helpful in assessing the prognosis and guiding the clinical treatment of comatose patients with severe traumatic brain injury.
