Objective To evaluate the efficacy and safety of Dextromethorphan Hydrochloride, Chlorphenamine Malente, and Ammonium Chloride Syrup on eliminating or relieving the symptoms of acute upper respiratory infections in children, by comparing with Guaifenesin, Dextromethorphan Hydrobromide, Methylephedrine Hydrochloride, and Chlorphenamine Maleate Syrup. Methods Random, blind and parallel control method was adopted. A total of 253 pediatric patients were recruited in 11 clinical research centers; 127 patients were assigned in experimental group and finally 118 patients were included in the program set analysis (PPS); 126 patients were assigned into control group and finally 116 patients were included in PPS. The experimental group took Dextromethorphan Hydrochloride, Chlorphenamine Malente, and Ammonium Chloride Syrup and control group took Guaifenesin, Dextromethorphan Hydrobromide, Methylephedrine Hydrochloride, and Chlorphenamine Maleate Syrup. All of the patients took as prescribed at least for 3 days but not more than 7 days. Results There was no significant differences in age, sex, and acute upper respiratory tract infection scores between the two groups (P?>?0.05). PPS showed the median time of symptom relief of acute upper respiratory tract infection in experimental group was 51.0 h (95%CI: 43.0-62.0 h) and 56.0 h (95%CI: 48.0-64.0 h) in control group. There was no difference between two groups (P?>?0.05). After calibration of center and baseline effects, the experimental group was not worse than the control group. There was no difference in the score of acute upper respiratory tract infection between two groups (F=0.14, P=0.710). The individual symptoms disappear rate of acute upper respiratory tract infection and the compliance between two groups were similar (P all?>?0.05). Both groups had 7 cases of adverse events, and one case of adverse drug reactions each. Thus, the adverse reaction rates in two groups were 0.8% each. Conclusions Dextromethorphan Hydrochloride, Chlorphenamine Malente, and Ammonium Chloride Syrup can effectively relieve symptoms rapidly in the treatment of children with acute upper respiratory tract infection, and its efficacy and safety were non worse than traditional Guaifenesin, Dextromethorphan Hydrobromide, Methylephedrine Hydrochloride, and Chlorphenamine Maleate Syrup.

Object detection systems are widely used in many fields. To speed up object detection, a rapid method based on color feature is presented in this paper. Artificial neural network is used for color classification. A series of original objects are gained through searching the most outstanding feature of the marker based on multi-resolution. A set of features obtained from these original objects in the original image, and artificial neural network are used for object classification. Experimental results prove the effectiveness of this method.

Lumbar disc herniation is a common male disease. In the past, More academic attention was directed to its relationship with lumbago and leg pain than to its association with andrological diseases. Studies show that central lumber intervertebral disc herniation may cause cauda equina injury and result in premature ejaculation, erectile dysfunction, chronic pelvic pain syndrome, priapism, and emission. This article presents an overview on the correlation between central lumbar intervertebral disc herniation and andrological diseases, focusing on the aspects of etiology, pathology, and clinical progress, hoping to invite more attention from andrological and osteological clinicians.

Multiple myeloma (MM) is malignant plasma cell clonal disease.Autologous stem cell transplantation (ASCT) strengthen the advantages of the high-dose chemotherapy in treatment of MM,which achieves long-term survival in some patients.Even in the era of targeted novel agents,ASCT can still obviously increase the response rate of treatment.To improve the therapeutic efficacy,targeted novel agents were administrated before and after ASCT.However,targeted novel agents still cannot replace ASCT therapy in the treatment of MM.The direction of future research is to find more reasonable,effective and low toxic treatment.

Objective: To explore whether short hairpin RNA (shRNA) targeting Bcl-2 can enhance the inhibitory effect of methotrexate (MTX) on growth of subcutaneously-transplanted human lymphoma in nude mice. Methods: Recombinant shRNA expression vector targeting the coding region of Bcl-2 mRNA was constructed and preserved in our lab. Human lymphoma Raji cells were injected subcutaneously into 45 nude mice to establish lymphoma models. The polyethylenimine (PEI)/shRNA complex and (or) MTX were injected into tumors. The influence of Bcl-2 shRNA and (or) MTX on tumor growth was observed. The animals were sacrificed 21 days after administration of drugs and the tumors were removed and weighed; the tumor inhibitory rate was calculated. H-E staining was used to observe the pathological morphology of the tumor. The expression of Bcl-2 mRNA in the tumor tissues was examined by RT-PCR. Results: The tumor growth was significantly slower in Bcl-2 shRNA/MTX group than in Bcl-2 shRNA or MTX alone groups (P<0.05). The tumor weight of mice in Bcl-2 shRNA plus MTX group was significantly lower than those in negative shRNA and blank plasmid group (P<0.05). The inhibition rate of tumor growth in Bcl-2 shRNA/MTX was significantly higher than those in the Bcl-2 shRNA or MTX alone groups (P< 0.05). H-E staining showed obvious apoptosis and necrosis in Bcl-2 shRNA group and MTX group. RT-PCR result showed that the expression of Bcl-2 mRNA in tumor cell suspension was significantly decreased in Bcl-2 shRNA group (P<0.05), and kept unchanged in the control group. Conclusion: The shRNA targeting Bcl-2 can enhance the inhibitory effect of MTX on the growth of subcutaneously transplanted human lymphoma in nude mice.

Objective The purpose of this study was to investigate the effects of propofol on the platelet function.Methods Thirty ASA Ⅰ-Ⅱ patients undergoing elective minor surgery were allocated into two groups: propofol group (n=20) and control group (n=10). The mean age of the patients was (37?8)yr. Patients who had blood disease or had been exposed to any medication with known platelet effects were excluded. The patients were premedicated with phenobarbital sodium 2mg?kg -1 and atropine 0.01 mg?kg -1. In propofol group anesthesia was induced with propofol 2 mg?kg -1, fentanyl 4?g?kg -1 and vecuronium 0.1 mg?kg -1 and maintained with 0.8%-1.2% isoflurane inhalation supplemented with fentanyl and vecuronium. The duration of operation averaged (85?15)min. Blood samples were taken from peripheral vein before induction of anesthesia, 5 and 30 min after induction and 1h after termination of propofol infusion for the assessment of CD62P,CD63 and CD41/CD61 on the platelet membrane surface by flow cytometry. Platelet count, bleeding time and ACT were also determined at the same time.Results Following the administration of propofol the expressions of CD62P and CD63 on the platelet membrane surface were significantly decreased, whereas the expression of CD41/CD61, platelet count, bleeding time and ACT did not change significantly.Conclusions Propofol inhibits the expression of platelet membrane glycoproteins CD62P and CD63 and may contribute to the impairment of platelet function.
