Surgery is an important way to treat patients with primary hyperparathyroidism.Recently,conventional bilateral neck exploration is substituted with minimal invasive surgeries gradually due to the development of the technology of pre/intro-operative localization.Video-assisted surgery is one of the minimal invasive surgeries.It includes video-assisted parathyroidectomy and total endoscopic parathyroidectomy.This article summarize the literatures of treatment of primary hyperpatathyroidism with video-assisted surgery in this article.

Objective To optimize the extraction process of Zushima Gel Cream.Methods Setting the content of daphnetin as an investigating index, and the amount of solvent, soak time and the extraction time as investigating factors, the orthogonal experiment was used to optimize the extraction process.Results The best extraction process was as follows:adding 30 mL water to degreasing Zushima Gel Cream;soaking for half an hour;extracting one time for two hours. The average content of daphnetin was 9.83 mg/g.Conclusion The extraction process is stable, reliable, and energy-saving. The study provided experimental evidence for the preparation process of Zushima Gel Cream.

OBJECTIVE:To evaluate the utilization status and trend of anti-vomiting drugs in our hospital. METHODS: The anti-vomiting drugs used in our hospital during the 2001～2006 were analyzed statistically in respect of drug kinds, dosage forms, consumption sum, DDDs etc. RESULTS: Both the drug kinds and the consumption sum of anti-vomiting drugs increased year by year in our hospital over 6 years, dominating the first place was 5-HT3 antagonists, of which, Ondansetron topped the list in consumption sum for five years and its DDDs ranked at the first place for 4 years. Domestic injections took the lead among all the anti-vomiting drugs. CONCLUSION: Consumption quantity of 5-HT3 antagonists has a rapid increase and which occupy a dominate place in our hospital.

Clinical trials are important means to push forward the development of human health. Every new drug needs to under-take clinical trials eventually to determine the efficacy and safety. In the paper, through our clinical trial experiences and extensive lit-erature retrieval, some problems of the communication management in clinical trials were analyzed and relevant countermeasures were suggested to improve the communication management in clinical trials in order to help the development of clinical trials.

AIM:To establish an effective and convenient method for applying HPLC fingerprints to quality control in the production of Shanzhuang Jiangzhi Tablet(Semen cassiae,Fructus crataegi,and Folium nelumbinis).METHODS:Diamonsil~(TM) C_(18)(150 mm×4.6 mm,5 μm)analytical column was used and eluted with a gradient program consisted of phase B(methanol)and phase D(1 % phosphoric acid)and detected at 254 nm;the column temperature was 30℃.The flow rate was 1.0 mL/min.RESULTS:Ten batches of sample tablets were tested and gained HPLC fingerprint of the tablet containing 17 common peaks.CONCLUSION:This validated method is available for quality evaluation and quality control in Shanzhuang Jiangzhi Tablet.

Objective To study the automatic word segmentation scheme suitable for traditional Chinese medical record literature. Methods Hierarchical Hidden Markov Model was used as segmentation model. Totally 300 ancient medical record literature and 300 modern medical record literature were set as experimental subjects to establish the dictionary of traditional Chinese medicine and the test corpus, with a purpose to segment the words and evaluate of the results. Results Without using dictionary of traditional Chinese medicine, the word segmentation accuracy of two kinds of medical record literature was about 75%;the part-of-speech tagging accuracy of ancient medical literature was 56.74%, the modern medical literature accuracy was 64.81%. By using dictionary of tradition Chinese medicine, the word segmentation accuracy of ancient medical record literature was 90.73%, the modern medical record literature accuracy was 95.66%;the part-of-speech tagging accuracy of ancient medical record literature was 78.47%, the modern medical record literature accuracy was 91.45%, which was obviously higher than that of ancient medical record literature. Conclusion The current word segmentation scheme has initially solved the problem of word segmentation of traditional Chinese medical record literature and part-of-speech tagging of modern medical record literature. Part of speech tagging is basically correct, but part-of-speech tagging of ancient medical record literature tagging needs further study for many influencing factors.

Human tumor necrosis factor-related apoptosis-inducing ligand (hTRAIL) might be developed as a novel anti-tumor drug due to its selective cytotoxicity in tumor cells. The predicted Macaca mulatta TRAIL (mmTRAIL) is highly homologous to hTRAIL in nucleotide acid as well as amino acid sequence, suggesting that mmTRAIL might induce apoptosis of human cancer cells. However, the cytotoxicity of mmTRAIL in human cancer cells has not been investigated. In this paper, it is reported that the gene encoding mmTRAIL has been cloned by using reverse-transcriptase polymerase chain reaction (RT-PCR) from monkey peripheral blood mononuclear cells (PBMCs) in our laboratory. Subsequently, an expression plasmid was constructed by inserting mmTRAIL gene into pQE30 plasmid. After induction by addition of Isopropyl β-D-1-Thiogalactopyranoside (IPTG), mmTRAIL was expressed. MmTRAIL was recovered from supernatant of sonicated bacteria by Ni-NTA agarose affinity chromatography. SDS-PAGE and gel filtration chromatography demonstrated that mmTRAIL forms trimer in solution. In vitro assays indicated that mmTRAIL was cytotoxic to human COLO205 tumor cells but not to normal cells at low concentration of nanomole. In addition, antitumor effect of mmTRAIL was evaluated in mice bearing human COLO205 tumor xenografts. Intratumorally injected mmTRAIL significantly inhibited growth of tumor grafts. These results suggested that mmTRAIL was valuable as candidate drug for cancer-targeted therapy.

An improvement of chemiluminescent system for determination of peroxynitrite anion (ONOO－) has been made. In this system, the effect of some antioxidants for scavenging ONOO－ was tested. The constitute of this system and the program of starting were followed as: The ozone (O3) was bubbled through a glass-frit into 10 ml 0.01 mol/L solution of sodium azide in CB(pH 10.5) to generate ONOO－. The 800 μl ozonized solution of azide was injected into a glass tude in situ which contains 100 μl sample and 100 μl luminol solutions to initiate chemiluminescence (CL). The pluses / 6 seconds (CP6S) were determined immediately and continually for 10～30 times. A certain CL intensity (CP6S) was chosen as evaluation index to compare the activity of antioxidants. This chemiluminescent system is sensible, simple and stable. The determination limit was 8.74 μmol/L ONOO－. The linear rang was 8.74～74.04 μmol/L ONOO－. The intra batch and inter batch variation coefficient (CV%) of the analysis were 3.35%(n=10) and 5.52%(n=10) respectively. It was tested that Vit.C, teapolyphenol, procyanidin and thiourea all have effects on scavenging ONOO－.

Objective To explore intervention efficacy of clinical application of antimicrobial agents in internal medicine departments of a hospital.Methods 1 880 medical records from internal medicine and pediatrics departments this hospital in July-December 2010 were randomly selected as control group (before intervention),and 2 207 medical records in July-December 2011 were as trial group (after intervention),antimicrobial use of two groups was compared.Results The over-all usage rate of antimicrobial agents after intervention was lower than before intervention (48.12% vs 58.62%,χ2 =44. 45,P <0.001).Except endocrinology,pediatrics and hematology departments,the usage rates of antimicrobial agents in the other departments after intervention were all obviously lower than before intervention(all P <0.05).The usage rate of antimicrobial agents in endocrinology and hematology departments were both low(<40%),which met the requirements of Ministry of Health.Conclusion Comprehensive intervention in clinical use of antimicrobial agents reduced the usage rate of antimicrobial agents in internal medicine and pediatrics departments in this hospital.
