Objective To explore the application of the ultrasonic cardiac output monitor(USCOM) in the children with pneumonia complicated with heart failure.Methods Fourteen children with pneumonia complicated with heart failure were enrolled in the experimental group and thirty-two children with common pneumonia were enrolled in the control group.We used the USCOM to measure the cardiac output indicators,including the aortic peak velocity,heart rate,stroke volume index,cardiac index,ejection time and correcting ejection time.Results The heart rate in the experimental group was faster than that of control group[(174 ±10) beats/min vs (133 ± 14) beats/min,P ＜0.05],the aortic peak velocity in the experimental group was lower than that of control group [(1.246 ±0.234) m/s vs (1.449 ±0.300) m/s,P ＜0.05],the stroke volume index in the experimental group was lower than that of control group [(29.357 ± 6.500) ml/m2 vs (40.188 ±5.337) ml/m2,P ＜0.05],and the correcting ejection time in the experimental group was shorter than that of control group [(342.560 ± 8.219) ms vs (354.430 ± 16.500) ms,P ＜ 0.05].Conclusion The cardiac function monitoring by USCOM is accurate and convenient,and USCOM can provide the accurate evidence for the clinical application.

By use of color Doppler ultrasonography (ATLHDI 5000,made in USA),a prospective study was made in 362 aged (greater than or equal to 60 years) patients (252 males and 110 females) for a period of 3 years.There were 176 patients (48.2%,130 males and 46 females) had degenerative vavular disease (DVD).The incidence increased with the aging of the population.There were no evident differences between males and females.Degenerative aortic valvular deformation was most frequently found (in 171 cases),followed by mitral (in 24 cases).The complications were hypertension,diabetes and coronary heart disease.It suggests that the DVD in the elderly mainly occurs in aortic valves,then in mitral value.Its incidence increases with aging.Complications such as hypertension,diabetes and coronary heart disease are important risk factors of DVD.

Objective To investigate the changes of lymphocyte subsets before and after the treatment with operation and chemotherapy in patients with breast cancer.Methods Using cytometer to measure lymphocyte subsets of CD3+,CD4+, CD8+,CD4+/CD8+ and NK of 25 breast cancer patients before and after treatment.The all 25 patients were treated with operation and chemotherapy after pathological diagnosis.The article compared the figures of T cell subsets before and after treatment.Results Compared with before operation and chemotherapy,the CD8+ statistically decreased after 1~3 months of treatment (t=2.57),and NK statistically increased after 3~6 (t=-2.23).After 6 months of treatment,the patients’ CD3+(t=-2.25),CD4+(t=-2.07)were statistically lower and NK (t=-3.56)was statistically higher.There was no significant difference for other items.Conclusion Lymphocyte subsets test against breast cancer patients can reflect immuni-ty level at a certain level during treatment.But how to explain the figures in different stage against treatment effectiveness and prognosis need further research.

Objective To study the effects of glycosaminoglycan extracted from Pinctada martensii on the proliferation, differentiation and mineralization of newborn rat calvarium osteoblast in vitro. Methods MTT, PNPP and ARS methods were used to measure the cell proliferation, activity of ALP and the function of mineral nodes formation of osteoblasts cultured in vitro. Results Glycosaminoglycan at concentration of 0.008～0.5g?L -1 inhibited mildly the proliferation of osteoblast cells, however, this range of concentrations of glycosaminoglycan markedly increased the ALP activity and stimulated mineral node bone formation in osteoblast. Conclusion Glycosaminoglycan extracted from the Pinctada martensii showed stimulating effects on the differentiation and mineralization of newborn rat calvarium osteoblast in vitro, but the stimulating effect on cells proliferation was not observed.

Objective Near-infrared (NIR) reflectance spectroscopy was used to develop a fast quality assessment method by simultaneous material identification and moisture quantification of Radix Ginseng Rubra (RGR). Methods The sample was identified by the comparison of its spectrum with a standard NIR spectral library. Similarity measurement was used as the discriminating parameter. The moisture content of sample was quantified by a partial least square (PLS) calibration model, correlative spectrum calculation was used for wavelength selection and multiplicative signal correction (MSC) was applied for pretreatment in the calibration model. Primary reference data were obtained using the traditional loss on drying (LOD) method. Results The NIR library can distinguish RGR from the counterfeit successfully. The optimized eight-factor PLS calibration model of NIR spectra has a high correlation coefficient (R=(0.999 7).) Conclusion The proposed method is rapid, accurate and can be used routinely in the traditional Chinese materia medica manufacturers for quality control of raw materials.

Objective To select the optimum conditions of the vacuum belt drying process of Radix Salvia Miltiorrhiza(RSM) extract.Methods The process was studied by using orthogonal test design and grading method for multi-index on the parameters of the water content of dried product and drying rate of RSM extract,the average quantity of vapour during unit time span,as the index.Results The optimum process determined by the grading method was listed as follows: water content of the extract before drying was 40%,the feeding speed was 1.5 mL/s,the belt speed was 5 cm/min.Conclusion This technology can increase the average quantity of vapour during unit time span and the drying product has high quality with lower water content and desirable drying rate.

OBJECTIVE: To evaluate the treatment effect, quality of life and side-effect of transcatheter arterial chemoembolization (TACE) and traditional Chinese medicine (TCM) in treating metastatic liver cancer. METHODS: Thirty-nine cases of colon metastatic liver cancer were randomly divided into two groups. Both TACE and TCM were used in the treatment group, while only TACE was used in the control group. The drug used in TACE included floxuridine, pirarubicin, cisplatin, and the herbs for strengthening the spleen and regulating Qi were used in TCM. RESULTS: The response rate in the treatment group was 30% (45% including minor remission patients), and the median survival time was 18.6 months. While in the control group the response rate was 15.8% (36.8% including minor remission patients), and the median survival time was 14.3 months. The 1-, 2-, 3- year survival rates of treatment group and the control group were 70.2%, 40.3%, 13.0% and 68.7%, 29.5%, 10.3% respectively. There were fewer other organ metastases in the treatment group. The score from the EORTC quality of life questionnaire QLQ-C30 in treatment group was higher than that in the control group. CONCLUSION: Integration of TACE and TCM in treating colon metastatic liver cancer has better results.

This experiment was designed to search and identify the active principle as well as the optimal proportion of water-soluble extractives of traditional Chinese medicine (water-soluble extractives) Liqi Huoxue medicinals com-patibility (Qixue Bingzhi Fang-CWQB) in the prevention and treatment of atherosclerosis (As) by optimal uniform design method. The water-soluble extractives of CWQB were divided into 6 sections (A, B, C, D, E, F) through macroporous resin. The effect intensity and step of every component were compared through its effect on blood fat level, platelet aggregation, inflammatory factors, vascular endothelial growth factor (VEGF) and so on among hyper-lipoidemia rat models. The pharmacological experimental results and statistical analysis showed that CWQB water-soluble extractives of component D (mainly is paeoniflorin, accounted for 49.12%), component E (mainly is total flavonoids, accounted for 30.0%) compatibility had better effects on decreasing blood fat and triglyceride (TG). Com-pared with the model group, there was significant difference (P < 0.01). It also had inhibiting effect on endothelin (ET) and maximum platelet aggregation rate (P < 0.01). The component F (mainly is total acids, accounted for 32.7%) had inhibiting effect on serum IL-6 and IL-8 (P< 0.01). It was concluded that different compatibility of wa-ter-soluble extractives of CWQB can be applied to different targets or steps of the body. The active principle extrac-tives include main component of paeoniflorin, flavonoids and total acids. The best proportion is about 1:1:1.

OBJECTIVE: To investigate whether the water extractives of regulating qi and blood prescription (WQBP) had effects on early atherosclerosis of apolipoprotein E-deficient mice (ApoE-mice) at the age of 19 weeks or not, and to explore the possible mechanisms. METHODS: Forty ApoE-mice, six weeks of age, were given high-fat diet and randomly divided into four groups: high-dose WQBP-treated group (360 mg/kg), low-dose WQBP-treated group (72 mg/kg), simvastatin-treated group (25 mg/kg) and untreated group, with ten mice in each group. Meanwhile, ten C57BL/6 mice of same genetic background were allocated to normal control group. Mice in the high- and low-dose WQBP-treated groups and simvastatin-treated group were administered with corresponding drugs from the 15 to 19 weeks. Mice in the untreated and normal control groups were administered with isovolumic water. Sacrificed at 19 weeks, the level of blood-lipid, the plaque construction, plaque integral, and the contents of plaque macrophages and vessel smooth muscle cells of the mice were analyzed by immunohistochemical method and a computer picture processing system. RESULTS: Compared to the untreated group, high-dose WQBP group could obviously decrease the level of low-density lipoprotein cholesterol (LDL-C). Simvastatin group could decrease the levels of LDL-C and total cholesterol (TC) (P<0.01). In high-dose WQBP-treated group and simvastatin-treated group, the thickness of fiber cap and the quantities of vessel smooth muscle cells increased (P<0.05), the quantities of plaque macrophages and the ratio of lipid and plaque reduced (P<0.01). CONCLUSION: WQBP and simvastatin can interfere in early atherosclerosis of ApoE-mice, attenuate and stabilize plaque in some extent. The mechanisms may include adjusting blood lipid, decreasing macrophage number and increasing the quantities of vessel smooth muscle cells.

This study was aimed to optimize the uniform design for effective constituents in water-soluble extractives D, E, F of traditional Chinese medicine (TCM) in Qi-Xue Bing-Zhi Fang (QXBZF) for the further validation of the ratio of different compatibility. A total of 100 SD rats were used in the study. Among them, 90 rats were given high fat feeding for 7 days. Then, stratified randomization was used. The rats were divided into the all-party group; D, E original prescription group; D, E optimized compatible group; D, E between optimized and original group; D, E optimized but anti-compatibility group; all-party group adding F; optimized compatible group adding F; QXBZF with mainly paeoniflorin accounted for 49.12% as component D, total flavonoids accounted for 30.0% as component E, total acids accounted for 32.07% in component F; the positive drug control group (Xue-Zhi-Kang, 0.108 g/kg); and the high fat model group. In addition, a blank control group (with normal diet) was set. Each group was treated with gastric perfusion according to drug compatibility proportion for 14 days. Rats were sacrificed to take blood samples for the detection of serum lipid, platelet aggregation, vasoactive substance, and inflammation level. The results showed that compared with the model group, the QXBZF D, E original prescription group and D, E optimized compatible group had significant decreasing effects on TC (P< 0.05). The lowest level of TC decreased by optimized compatible group was (3.49 ± 0.86) mmol/L. The all-party group, D, E original prescription group and optimized compatible group can inhibit the platelet with maximum aggregation rate effectively(P< 0.05, P< 0.01); while the D, E optimized but anti-compatibility group (with D, E inverse proportion) had no effect on it. All-party group and the D, E original group adding F had significant inhibition on IL-6 and IL-8 (P < 0.05, P < 0.01). The D, E original prescription group, D, E optimized compatible group and D, E between optimized and original group can ascend 6-Keto-PGF1α significantly (P< 0.05). ET-1 was decreased in the D, E optimized compatible group (P< 0.05). Other groups had no obvious effect on vascular active substances. It was concluded that different effects between the QXBZF D, E original prescription group and the D, E optimized compatible group were observed in action segment and strength. When F parts added, inhibitions of inflammation levels were enhanced at certain level.
