ObjectiveTo observe the effect of integrated traditional Chinese medicine therapy on pelvic inflammation. Methods40 patients of chronic pelvic inflammation were as the group of integrated traditional Chinese medicine therapy and received Chinese herbal medicine treatment (by taken orally, clysis and hot compress), acupuncture, mental state therapy etc. Other 36 cases were as the control group and only received Chinese herbal medicine treatment by taken orally. Then effects of two groups were compared. ResultsIt shows that the group of integrated traditional Chinese medicine therapy got obviously better results than the control group (P<0.01). ConclusionsThe integrated traditional Chinese medicine therapy is more effective on chronic pelvic inflammation.

Objective To study the velocity pattern of ischemic myocardium change during systolic phase by Doppler tissue imaging(DTI). Methods Twenty-three dogs were investigated as two groups. In 13 open-chest dogs as group A, regional wall motion abnormalities were induced by occluding branches of left circumflex coronary arteries(LCX). Left ventricular(LV) wall systolic velocity patterns at the mid-wall portion of the middle of LV posterior walls in the short-axis direction were recorded with DTI before and after artery occlusion. Ten dogs as group B were operated to occlude branches of LCX. Before and one week after operation the same parameters were recorded by transthoracic method. Results There were positive velocity peak(IVC 1), negative velocity peak(IVC 2) during isovolumic contraction and positive velocity peak(S) during ejection in DTI spectra of all normal LV posterior walls. The peak velocities of IVC 1 and S decreased significantly, but the peak velocity of IVC 2 increased significantly after occluding branches of LCX in both groups (P

Objective To explore the effect of Renzhu Jianwei Granules(Granule of Semen Coicis and Rhizoma Atractylodis Macro- cephalae for strengthening the stomach)on the patients with precancerous lesions of gastric cancer(PLGC)and its mechanism. Methods The 58 patients of chronic atrophic gastritis(CAG)complicated with intestinal metaplasia(IM)and/or dysplasia(Dys) were randomized into treatment group and control group with 29 in each.The treatment group was administered Renzhu Jianwei Gran- ules while the control group was given Weifuchun Tablets.The numbers of positive cells of carcinoembryonic antigen(CEA)and cy- clooxygenase 2(COX-2)of gastric mueosa before and after treatment were observed.Results The scores of positive cells of CEA and COX-2 of gastric mucosa of both groups were greatly reduced after treatment(P0.05).Conclusion Renzhu Jianwei Granules can reduce CEA and COX-2 of PLGC patients,possibly being one of the mechanisms in treating PLGC.

Objective: To optimize the formula and preparation process of docetaxel-loaded pluronic P123 micelles. Methods:Docetaxel-loaded pluronic P123 micelles were prepared by a thin-film hydration method and optimized by central composite design and response surface methodology. The influencing factors including the quantity of docetaxel, volume of organic phase, volume of hydra-tion and temperature of hydration were investigated with the entrapment efficiency as the index. The morphology of micelles was ob-served under a transmission electron microscope. The particle diameter and zeta potential were determined. The in vitro release property was measured by a dialysis method. Results:The relationship between the influencing factors and the evaluation parameter was fitted by multi-linear equation, quadratic polynomial equation and cubic polynomial equation, respectively. The results showed that the cubic polynomial equation was superior to the others according to the correlation coefficient. Docetaxel-loaded pluronic P123 micelles were spherical with the mean diameter, zeta potential, polydispersity index, encapsulation efficiency and drug loading of 108. 3 nm,-3. 99 mV, 0. 265, (97. 91 ± 0. 28)% and (3. 72 ± 0. 12)%, respectively. The cumulative release in vitro reached 95. 03% in 120 h, and docetaxel-loaded pluronic P123 micelles had notable sustained-release property. Conclusion: The technical process for do-cetaxel-loaded pluronic P123 micelles is simple and usable, and docetaxel-loaded pluronic P123 micelles show high encapsulation effi-ciency and notable sustained-release property.

Magnetic resonance diffusion-weighted imaging (MR-DWI) is a functional technology at the molecular level.Compared to other imaging exams (such as DSA,CT,US),DWI is non invasive,has no radiation,and objective.Thus,it is widely accepted in clinical settings.As a means to assess the therapeutic efficacy of intervention,DWI has a promising prospect.In this article,we review the application of MR-DWI in evaluating the therapeutic efficacy of hepatocellular carcinoma intervention.

Objective To establish a rapid and convenient assay to screen for emerging ganciclovir(GCV) resistant mutations in the UL97 gene of human cytomegalovirus (HCMV) from transplant recipients. Methods Thirteen spefcific oligonucleotide probes were designed according to the target sequence encoding HCMV-UL97 gene. A nested polymerase chain reaction (PCR) amplifying UL97 gene was employed. Line probes assay (LiPA) was configured to detect relevant non-synonymous mutations at codon 460,520,594,595,603, and 607. In parallel, nested-PCR amplicons were subsequently sequenced directly. Results Four of 16 heart and lung transplant recipients had been infected with HCMV resistant strains during GCV therapy. The mutant codons of UL97 gene were at codon 520、595 and 603. All amplicons detected by LiPA were fully concordant with the nucleotide sequenced.Conclusions Long-term prophylaxis and treatment with GCV in heart and lung transplant recipients may develop HCMV resistant strains. HCMV-LiPA proves to be an alternative method for the resistance genotype analysis of HCMV.

The HPLC fingerprint determination method of Jinzhen oral solution was established to provide a new method for quality control of Jinzhen oral solution. RP-HPLC was used for phenomenex Luna C18 (4.6 mm x 250 mm, 5 μm) chromatographic column, with 0.1% H3 PO4 water solution and acetonitrile as the mobile phase for gradient elution. The detection wavelength was 280 nm. HPLC fingerprint of Jinzhen oral solution was established to identify 17 common peaks in Jinzhen oral solution. The similarity of fingerprints of 10 batches of finished products was more than 0. 90. The established HPLC fingerprint has a better precision, reproducibility and stability, and can be applied in quality control of Jinzhen oral solution.

Objective To analyze the factors which influence the present nursing management ability in the alliance and to provide theoretical evidences and methods to improve the management. Methods 120 nursing administrators from 7 hospitals in the alliance were selected in convenience sampling for the site survey with customized questionnaires on nursing management ability appraisal. Results The valid return rate of the questionnaires is 100%;the average score of all respondents is 82.84±10.10;the differences in nursing management between the leading hospital and its members are statistically significant (P <0.05)while the differences among the members are not.Conclusion The leading hospitals play a very important role in improving the nursing management ability and administration in the alliance,which should integrate and leverage leadership roles to develop high quality nursing management among the hospitals in the alliance.

Objective To know the mastery degree of percutaneous coronary intervention (PCI) preoperative nursing knowledge in nurses who are working in emergency department and cardiac ward. Methods 158 cases of nurses who came from three different class Ⅲ grade hospitals with qualification for emergency PCI surgery of the Guizhou province were surveyed with self-made questionnaire. The survey was conducted in nurses who were working in different departments, and the educational background, age, title, category, the cognitive situation of the PCI preoperative nursing knowledge and necessity of preoperative preparations were investigated in nurses. Results The whole pass rate was 48.10%; high qualification, high education, higher title of nurses for the nursing knowledge of the emergency PCI were better; the emergency PCI preoperative preparations for the necessity of cognitive about nurses were on the low side. Conclusion The cognition of the nursing knowledge and the necessity of emergency PCI in preoperative preparations as whole are on the low level, so specialized training should be strengthened to enhance the ability of specialized nursing.
