OBJECTIVE:To observe the clinical efficacy of herbal desensitizer in the treatment of dentine hypersensitivity. METHODS: 126 patients with dentine hypersensitivity were enrolled: 64(a total of 172 diseased teeth) were randomly assigned to trial group to be treated with herbal desensitizer,and 62(158 diseased teeth) to control group to be treated with sodium fluoride glycerin. The clinical effects observation was scheduled immediately,3 and 6 months after the treatment. Then the results were analyzed using statistics software.RESULTS: Significant differences were found between the trial group and the control group in clinical effects (P

Objective To identify the causes of coronary angiographic hazy lesions by intravascular ultrasound (IVUS) to avoid inappropriate stenting. Methods Twenty-five cases with hazy regions on coronary angiogram were consecutively identified from July 2009 to March 2010. Hazy regions were defined by coronary arteriongraphy as reduced contrast density without a clearly defined intimal tear, dissection,thrombus,or stenosis ( ＞ 50% ). This cohort of patients were subsequently underwent IVUS examinations and treated according to the results of IVUS. Results The lumen CSAs were settled as ＞ 4. 0 mm2 in all examinations. Among all 25 cases,hazy lesions were located in left anterior descending in 12 patients, right coronary artery in 6 patients, left circumflex in 5 patients, and left main artery in 2 patients. According to the IVUS findings, 2 cases showed absolutely normal or near-normal arterial wall structure image, 10 cases showed calcified plaque,5 cases showed plaque rupture,3 cases showed eccentric plaque ,2 cases showed thrombosis formation,2cases showed dissection,1 case showed subintimal hematoma. Seven patients received stent implantation, and the rest accepted medical therapy. There were no in-hospital MACEs reported among all patients. Conclusion Nearly half of the coronary arteriongraphic hazy lesions were caused by calcified plaque. IVUS can distinguish calcified plaques from intimal tears, thrombus and other underlying etiologies,and help to avoid unnecessary stenting.

The fabrication system for the electrochemical microfluidic device was set up based on the pulse driving and controlling of microfluids technology.The nano silver ink and glycerol solution were jetted on the glass substrates to form the microelectrode pattern and the liquid mold pattern for the microchannel.Then the microelectrode and microchannel were obtained through a sintering process and a molding process, respectively.The electrochemical mircrofluidic device was Finally prepared through a bonding process with the microelectrode and the microchannel.The influences of the system parameters on the formation of the droplet were studied, as well as the influences of the droplets diameter and the overlap on the formation of the liquid lines.The minimal width, the thickness and the resistance of the prepared microelectrode were 45 μm, 2.2 μm and 5.2 μΩ cm, respectively.The minimal width of the microelectrode was 35 μm and the surface was smooth.The electrochemical flow detection of glucose concentration was carried out with the device, and the results showed that the glucose concentration had a high linear correlation with the response current, which could be used in the quantitative detection of glucose concentration.The fabrication of the electrochemical microfluidic device based on the pulse driving and controlling of micro fluids technology has many advantages such as simple system structure, lower cost and higher accuracy of the micro droplet and can be used in the preparation of the devices in the biochemical analysis and biosensor areas.

Objective: To observe the effect of polysaccharide ingredients from six TCM complex prescriptions on releasing the cytokine(CK) level of mouse celiac macrophages (M?), to explore the possible mechanism and direct the extractionand separation of active components for above compounds. Methods: The total polysaccharide ingredients of six complex prescriptions were prepared: Siwu Decoction, Sijunzi Decoction, Liuweidihuang Decoction, Guizhi Decoction, Longdanxiegan Decoction and Yupingfeng Pulveres, then the mouse celiac M? were incubated together in 96 holes board. Furthermore, levels for the latter to release CK, including IL-1?, IL-6, IL-8 and TNF-?, were measured. Results: Polysaccharide ingredients of each complex prescription could obviously accelerate mouse celiac M? to release one or more CK, and the e ects had concentration otherness (P

AIM:To establish macrophage mannose receiver Model(MMR),and use it to screen active component with mannose receiver(MR)as target from traditional Chinese herbs.METHODS:The mouse abdominal macrophages was hatched with D-mannose and D-galactose of the different concentration,and the flow cytometry and fluorescence microscope were used to measure the antagonistic effect of M-FITC-BSA(Mannose-fluorescein isothiocyanate-bovine serum albumin)with D-mannose and D-galactose.After the MMR screening model was established to screen MR union ingredients of polysaccharide ingredients from six compound prescriptions,such as Siwu Decoction and so on.RESULTS:Both of measuring methods showed that when D-mannose concentration increased the relevance ratio of M? marked with M-FITC-BSA decreases(P

Objective:To analyze the medication of one patient with ulcerative colitis to provide pharmaceutical care and support for rational drug use in patients with ulcerative colitis. Methods:During the treatment of the patient with severe ulcerative colitis, clin-ical pharmacists analyzed the drugs used by the patient and provided pharmaceutical care for doctors and the patient according to the ex-amination and diagnosis of the patient. Results:The compliance, therapeutic effect and medication safety of the patient were all im-proved by giving clinical drug rationalization suggestions and targeted medication monitoring and education, which fully embodied the necessity of work of clinical pharmacists in the medication of patients. Conclusion:Through case analysis, clinical thinking of clinical pharmacists can be developed to promote rational drug use, avoid adverse drug reactions and achieve optimal effect of drug treatment.

AIM: To explore the effects of heme oxygenase-1(HO-1) protein expression induced by ginkgo biloba extract(EGB761) in rat vascular smooth muscle cells(RVSMC) and the correlative cell signaling pathway.METHODS: The RVSMC lines were revived.Serial passage to 6 generation was carried out and divided into different groups.The cells were treated respectively with vehicle,purely EGB761,EGB761 plus zinc protoporphyrin IX or other specific inhibitors of cell signaling pathway.Western blotting method was used to detect the expression of HO-1 in RVSMC.RESULTS: EGB761 induced HO-1 protein expression in a dose dependent manner.ZnPPⅨ and genitein significantly inhibited HO-1 protein expression induced by EGB761(0.10?0.01,0.07?0.01 vs 0.61?0.07,P0.05,respectively).CONCLUSION:(1) EGB761 significantly induces HO-1 protein expression in RVSMC,and the effect can be inhibited by a specific HO inhibitor ZnPPⅨ.(2) The HO-1 protein expression induced by EGB761 in RVSMC is mediated by tyrosine protein kinase pathway.

Objective To investigate the clinicopathogenical significance of phosphorylation type of c-jun N-terminal kinase(p-JNK)and muhidmg resistance protein P-glycopretein(P-gP),multidrug resistance proteinl(MRP1)and lung resistance protein(LRP)in gastric cancer. Methods The expression of p-JNK,P-gP,MRP1 and LRP was detected in a tissue microarray containing 168 spots of gastric cancer tissue and 27 spots of normal gastric tissue by immunohistochemistry.Results The positive expression rate of p-JNK,P-gp,MRP1 and LRP in gastric cancer wag 45.8%,51.8%,45.8%and 55.4%respectively,which Was significantly higher than that in normal gastric tissue(P＜0.05).The p-JNK expression correlated with depth of invasion(P＜0.01),histology grade(P＜0.05),vessel invasion (P＜0.01),lymph node metastasis and distant metastasis(P＜0.01).The expression of p-JNK,P-gp and MRP1 in a positive relationship(P＜0.05).Kaplan-Meier analysis revealed a significant impact on survival by p-JNK,P-gp and MRPl(P＜0.05). Conclusion The p-JNK expression in gastric cancer is correlated with malignant biological behavior and may be involved in the chemotherapeutic resistance by upregulating the expression of P-g[ and MRP1.
