Objective To compare the clinical effect of povidone-iedine cream plus vagina scrubbing with traditional preoperative vaginal preparation method in order to seek a more safe,effective,convenient and efficient method to prepare the vagina.Methods 100 cases of married patients undergoing elective gynecological surgery were divided into the observation group and the control group with 50 patients in each.The observation group adopted povidone-iodine cream plus vagina scrubbing and the control group used traditional method.Two groups were prepared in the vagina before and after taking cervical swabs for bacterial culture to compare the positive rate of bacterial culture.Results Intra-group comparison of vaginal bacterial culture before and after vaginal preparation was significantly different,but no statistical significance was seen between the two groups.Conclusions Vagina preparation with povidoneiodine cream plus vagina scrubbing can not only reduce the workload of nurses but also improve patient comfort degree.

Objective To observe the degeneration of Brugia malayi in Meriones unguiculatus model. Methods Microfilaria of Brugia malayi derived from Meriones unguiculatus was used to infect Anopheles sinensis . Infective stage larvae (L 3) from mosquito vector were collected and inoculated into abdomen of Meriones unguiculatus. Successive 33 generations of the parasite in the rodent model have been observed. Results Since 1974 when the animal model was established, the parasite has lasted for 33 generations, the positive rate of Meriones unguiculatus with microfilaria gradually reduced from 80% of the 28th generation to 16% of the 32nd generation and finally to 0 at the 33rd generation. Conclusion It became difficult for the larvae of Brugia malayi to develop and/or reproduce in the animal model after multiple inoculations for generations.

Plasma HDL, HDL2 and HDL3 were determined in 95 untreated and 87 treated patients with NIDDM and 86 cases with IGT using Eder's modified method.The result showed that HDL, HDL2 and HDL3 were all reduced in these three groups in comparison with control group, but the average concentrations of all 3 subfractions of HDL showed no significant difference among these three groups. It also indicated that HDL abnormality may appear quite early in cases with abnormal glucose tolerance, such as in patients with IGT.

ObjectiveTo study the optimal power of self-made polymeric microcapsules with liquid perfluorocarbon enhancing high intensity focused ultrasound (HIFU) ablation of normal bovine in vitro and the treatment efficacy of HIFU ablation of normal rabbit liver in vivo.Methods The experiment was divided into two parts:the first part was HIFU ablation of bovine in vitro:The bovine was injected different drugs before HIFU ablation to find the optimal power and treatment time.It was divided into four groups:①HIFU + 0.9％ NaCl(NACL) group; (② HIFU + poly( lactic-co-glycolic acid) (PLGA) group; ③ HIFU + perfluorohexane(PFH) group; ④ HIFU + PLGA + PFH group; The second part was HIFU ablation of normal rabbit liver.Similarly,It was also divided into four groups as above.Each group was undergone HIFU ablation with same parameters after ear vein injection of drug.Then the ultrasonographic changes and its value,and the actual situation of liver damage in target areas of each group were observed and compared before and after the ablation area.ResultsIn experiments of vitro bovine,gray scale changes and coagulation necrosis could be seen in the liver in group 2,3,4 with HIFU power of 150 W and treatment time of 2 s.In experiment of normal rabbit liver,the average gray-scale of group 3 and 4 were larger than that in group 1 and 2,the difference was statistically significant (P ＜0.001),and its gray change area gradually reduced with time elapsed.While there was no statistically significant difference between group 3 and 4 ( P ＞0.05).In pathological specimens,there was no significant liver damage in group 1 and 2.There was hemorrhagic necrosis and white coagulation necrosis in group 3 and 4.Conclusions The polymeric microcapsules with liquid perfluorocarbon can effectively enhance the efficacy of HIFU ablation and be used as a good synergist for HIFU.

Objective Using infrared spectroscopy to analyze three kinds of lignum Chinese medicine to provide a theoretical basis for the establishment of medicinal overall quality evaluation system. Methods Functional groups identification, Fourier Transform-infrared spectroscopy(FT-IR) and the second derivative infrared spectroscopy (SD-IR) could be applicable to analyze and identify the overall chemical composition of three kinds of lignum Chinese medicine. Results The main chemical components of Aquilariae Lignum Resinatum (ALR), Dalbergiae Odoriferae Lignum (DOL) and Sappan Lignum (SL) were cellulose, lignin and aromatics. The main chemical compositions of Sappan Lignum (SL) were cellulose, lignin and aromatics. The differences in FT-IR and SD-IR of DOL and SL indicated that they had different aromatic compounds. Conclusion Infrared spectroscopy can be used as a simple and accurate quality control method of three kinds of lignum Chinese medicine.

Primary liver cancer is one of the most common malignances worldwide, among which hepatocellular carcinoma (HCC) accounts for about 90% of all cases. Multidisciplinary multimodality therapy involving surgery, ablation, interventional treatment, targeted therapy, and immunotherapy is an effective strategy for the treatment of liver cancer. In recent years, great achievements have been made in multimodality therapy for liver cancer, especially the advances in combination therapy for advanced liver cancer and drug research and development, which improves the overall prognosis of liver cancer patients, and the improvement in targeted drug therapy and immunotherapy is expected to change the pattern of multimodality therapy for liver cancer. This article systematically reviews the recent advances in multimodality therapy for liver cancer from the aspects of local treatment and systemic therapy.

Objective To provide effective reference for quality analysis of the chemical composition and extraction of astragalus separation process by comparing the extract of astragalus and it’s IR spectra. Methods The saponins and flavonoids in astragalus were firstly extracted by the method of circumfluence with ethanol as solvent and the residue of ethanol-extraction was then used to extract polysaccharides by distilled water. Fourier transform infrared spectroscopy (IR) combined with second derivative infrared spectroscopy was applied to quickly identify astragalus herbs powder, water extraction of astragalus, astragalus alcohol extraction and water extraction of the residue of ethanol-extraction. Results The powder and 70% ethanol extract, 80% ethanol extract were around at 1 735 cm-1 (carbonyl stretching vibration absorption peak) has a weak, broad absorption, while the absorption peak was less obvious in boiling water extraction. So the maln components of astragalus water extraction are polysaccharides and also contaln a small amount of water-insoluble flavonoids. Alcohol extraction malnly contalns saponins and flavonoids, and flavonoid extract volume increases with increasing alcohol concentration in a certaln range.Conclusion This method can be a quick and easy identification for astragalus and it’s extraction for its chemical composition class, and provide the basis for further research quality.

Objective To summarize the clinical experience of one stage hybrid operation for aortic arch replacement and explore the indication. Methods From July,2009 to March,2010, 22 consecutive patients received one stage hybrid operation in our hybrid suite for aortic dissection or aortic aneurysm involving aortic arch. Two operative methods are used. (1)Bypass from ascending aorta to brachiocephalic arteries using midstemotomy and normothermia with antegrade aortic arch endovascular stented graft implantation. (2) Ascending aorta replacement and/or aortic valve replacement and/or coronary artery bypass grafting using midstemotomy and cardiopulmonary bypass with antegrade aortic arch endovascular stented graft implantation. Results All patients were technically successful. Angiography during the operation showed 100% patency of all the bypass grafts and no obvious translocation or endoleak of the stents. One patient in the first group died on sixth day after operation due to distal dissection rupture. There was one case of mediastinal lymph effusion in the second group and one case of death due to renal failure and respiratory failure 12 days after operation in the second group. The ICU stay and hospital stay were obviously shorter in hybrid open chest group than that in traditional open chest operation group(P ＜0.05). The blood product consumption and expenditure were also obviously less in hybrid open chest group than that in traditional open chest operation group (P ＜0.05). All the patients were followed up with a mean period of (14.45 ±2.33) months (range: 12 -20 months). All other patients were recovered with normal social life. CT showed neither endoleak nor translocation of the stented grafts. Faulse lumen closure rate at stented-graft segment is 100%. There was no obvious change of distal part of the dissection three months after operation except some thrombosis formation in some of the false lumen. Conclusion One stage hybrid operation for aortic arch replacement is safe and effective in shortening the duration of the operation and reducing the surgical trauma and risk of interval between procedures, shortening the hospital stay and reducing the blood product consumption compared with conventional operation with satisfactory early results. The midterm and long term results are still needed to be followed up.
