Objective:To study the surface enhanced Raman scattering ( SERS) of safflower and identify safflower injections by SERS quickly and effectively. Methods:Through comparative analysis of the Raman spectroscopy of safflower injections and the corre-sponding control herbs, the rapid identification of safflower injections was realized. Results:The results showed that several character-istic peaks of safflower were enhanced obviously in SERS, which could be used to identify safflower injections. Conclusion:The meth-od is reliable, rapid, accurate and specific, which can be applied as a method to identify safflower and its injections.

Objective To observe the effects of Uremic Clearance Granule combined with angiotensin receptor blockers (ARB) or angiotensin converting enzyme inhibitors (ACEI) in treating different period of diabetic nephropathy (DN ) .Methods 46 patients with DN were divided into the control group and the treatment group ,23 cases in each group .The two groups were given the rou-tine hypoglycemic therapy .The control group was treated with ACEI or ARB ,while the treatment group was given Uremic Clear-ance Granule 5 g each time ,four times daily for successive 4 weeks .Then the indexes of serum creatinine ,blood urea nitrogen ,cysta-tin-C ,microalbumin and 24 h urine total protein at 24 h before and after treatment were observed .Results The microalbumin and 24 h urine total protein after treatment in the two groups were reduced compared with before treatment (P<0 .01) .In the patients with the stage Ⅲ of DN ,the urine protein decrease after treatment had no statistical difference between the two groups (P>0 .05) . In the patients with the stage Ⅳ of DN ,on the basis of ACEI or ARB adding Uremic Clearance Granule could significantly decrease the urine protein(P<0 .05) .Conclusion ACEI or ARB combined with Uremic Clearance Granule has definite effect for treating massive proteinuria of DN .

Recently,paclitaxel has been used as a new agent on patients with advanced esophageal cancer,and several studies have demonstrated that paclitaxel and paclitaxel-based regimens have significant activity in patients with advanced esophageal cancer and showed highly response rates than the combination of 5-fluorouracil (5-Fu) and cisplatin.However,there have been some problems which need to be solved such as drug-resistance,side effect,and so forth.The new medicament form of paclitaxel can not only depress poison without anti-allergy but also raise medicament curative effect as well as the pharmacal concentration.Although most of the research on the new medicament form of paclitaxel are still limited in the stage of laboratory,it has possessed potential advance in the treatment of advanced esophageal cancer.

OBJECTIVE: To explore the effect of treating periarthritis of shoulder with manipulation through evaluating clinical reports with the theory of evidence-based medicine (EMB). METHODS: By retrieval of some main medical literature databases in the past 5 years, 242 articles on treating periarthritis of shoulder with manipulation were available. Selected by admission standard, 10 of them were evaluated with EBM theory. RESULTS: Both single-application and union-application of manipulation were effective to periarthritis of shoulder, but the evaluated articles were all low-quality articles. CONCLUSION: Because of low quality clinic test and larvaceous publication bias, the extant evidence is not enough to recommend replacing other therapeutic methods by manipulation. The low quality of evaluated articles suggests that there exist some methodology problems in the clinic test on treating periarthritis of shoulder with manipulation.

Objective Statistics and analyze the effect of comprehensive prevention measures for the ventilator associated pneumonia (VAP) morbidity and mortality,and investigate its actual applicate situation in the clinical.Methods Statistics and analyze the clinical date of 183 cases of our ICU mechanical ventilation patients in 2012 (group A),including morbidity,mortality,time of endotracheal intubation,length of stay and the primary pathogenic bacteria,and to compared with the relevant clinical data of 192 cases of our ICU mechanical ventilation patients in 2011 (group B),summarize and analysis the actual applicate situation of the comprehensive prevention measures in the clinical through the data contrast.Results The incidence of VAP in group A was lower than that in group B [31.7％(58/183) vs.58.3％(112/192)] (P ＜ 0.05),but the mortality was no statistical difference in both groups (P ＞ 0.05) ; the endotracheal intubation time and the average length of stay in group A were less than those in group B [6.3 d vs.10.6 d,7.6 d vs.11.9 d](P＜0.05); the main pathogenic bacterium of VAP with mainly gram-negative bacilh.Conclusions Comprehensive prevention measures can effectively reduce the incidence of VAP,but the mortality rate has no significant effect,need further clinical research;comprehensive prevention measures to reduce patients with tube time also confirm its effectiveness.Comprehensive prevention measures are economical and practical,is worth in clinical promotion.

Objective To explore the relationship between calcium channel ?1 subunit (Cav1.1) gene intron 26 -67 A/G polymorphism and thyrotoxic periodic paralysis(TPP). Methods Cav1.1 gene polymorphism at position -67 was determined by polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) in 46 male patients with TPP, 68 male Graves’ disease (GD) patients without TPP and 72 healthy male controls. The difference of genotype and the variation of allele frequencies were analyzed by Chi-square test. Results (1) Frequencies distribution of AG+GG genotype in TPP, GD and control groups were 47.83%, 14.71% and 29.17% respectively, and those of allele G were 44.57%, 13.24% and 27.78% for the three groups respectively. (2) Frequencies of -67 AG+GG genotype in TPP group were significantly higher than those in GD and CON group(OR=5.32, P

0.05);and in combined test,the combined ORe=0.989 7 and ORs=0.565 7 with the combined ORe and ORs(at 95% confidence interval)stood at 0.783 6～1.248 4 and 0.418 8～0.764 1,respectively.In OR combined test:?2=13.790 9(P

The effects of monoterpene perilly alcohol (POH) alone or in combination with STI571 on the proliferation and apoptosis of the cell line K562 positive for Bcr/Abl were investigated. By using cell culture, the effect of the drugs on the proliferation of the cells was studied. TUNEL and flow cytometry assay of FITC-Annexin V and PI labeled cells were applied to detect the effects of the drugs on the apoptosis of the cells. The results showed that at 36 h, IC50 of POH on K562 positive for Bcr/Abl and HL-60 negative for Bcr/Abl were 81.0 +/- 11.3 micromol/L and 113.6 +/- 23.4 micromol/L respectively (P>0.05). POH could inhibit the proliferation of K562 in a time- and dose-dependent manner with the inhibitory rate of 100 micromol/L POH on K562 cells at 36 h being (53.2 +/- 3.65)%. K562 cells were more sensitive to STI571 than POH. IC50 of STI571 on K562 cells in 36 h was (0.256 +/- 0.054) micromol/L. In a time- and dose-dependent manner, POH induced the apoptosis of K562 cells with the percentage of apoptotic cells by 100 micromol/L POH at 40 h being (21.0 +/- 3.3)%. Both 100 micromo/L POH and 0.2 micromol/L STI571 had the same inhibitory effects on the K562 cells at 36 h. But at 12 and 24 h, the inhibitory rate of POH was significantly higher than that of STI571 (P<0.05) and the ability of STI571 inducing apoptosis at 36 h was greater than that of POH. 50 micromol/L, 100 micromol/L and 200 micromol/L POH in combination with 0.2 micromol/L STI571 could obviously increase the inhibitory effects on the cellular proliferation. Combined use of 50 micromol/L, 100 micromol/L, 200 micromol/L with 0.2 micromol/L STI571 could strongly induced apoptosis, especially 200 micromol/L POH in combination with 0.2 micromol/L STI571. It was concluded that the antileukemia effect of POH had no obvious Bcr/Abl positive selectivity. POH can inhibit the proliferation of K562 and induce the apoptosis in a time- and dose-dependent manner. K562 cells were more sensitive to STI571 than POH. POH in combination with STI571 could obviously enhance the abilities of STI571 inhibiting the proliferation and inducing apoptosis of K562 cells.
