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 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.

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 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 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.

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 study the molecular mechanism of renal injury of chronic arsenic poisoning rats induced by the expression of cysteine caspase-8 and P53 in renal proximal tubular epithelial cells.Methods Sixty healthy SD rats were divided into three groups,high-,low-dose group,and control group,n =20 in each group.The rats in high and low dose groups were treated with As203 through drinking water,10.0 and 0.4 mg/kg,respectively.The control rats were given distilled water.Four months later,serum and urinary arsenic level was determined,and kidney specimens were taken.The expression of cysteine caspase-8 and P53 in renal proximal tubular epithelial cells was detected by histological technique-HE staining and SABC immunohistochemistry.In addition,cell number counting and image analyses were used in the study.Results The number of caspase-8 positive cells of renal proximal tubule in control group,low-and high-dose group was 3.33±1.32,31.14±8.02 and 46.50±7.20 cell number/visual fields,respectively,which was increased with dose increasing(all P ＜0.05);the average gray value was 151.34±6.40,133.58±4.63 and 128.34±16.28,respectively,decreased with dose increasing(all P ＜0.05).The number of P53 positive cells was 3.17±1.59,26.29±4.23 and 47.00±6.22 cell number/visual fields,respectively,increased with dose increasing (all P ＜ 0.05) ; the average gray value was 142.54±8.06,121.48±5.68 and 101.89±6.35,respectively,decreased with dose increasing (all P ＜ 0.05).Conclusion The increase of caspase-8 and P53 positive cells is one of the molecular mechanisms of renal injury induced by arsenic poisoning.
