[ABSTRACT]OBJECTIVETo explore the efficacy and safety of localization for parathyroid glands with intravenous low dosage of methylene blue in thyroidectomy. METHODSWe retrospectively reviewed the clinical data of 41 patients who suffered from thyroid papillary carcinoma between Aug, 2014 and Jan, 2015 (9 males and 32 females, with a median age of 46 years). Thirty eight patients underwent primary thyroidectomy and 3 patients underwent second operation. A variety of thyroidectomy was performed in all patients, and who also underwent intravenous (3-4) mg/kg methylene blue in operation. RESULTSEighty four parathyroid glands were stained. Among 39 patients who's parathyroid glands were stained, the mean dyeing time was (31.27±9.41) min. Dyeing rates and dyeing time were not significantly different between 3 mg/kg group and 4 mg/kg group (t=0.24 and 0.20, all P>0.05). None of patients had the hypoparathyroidism problem such as peri-oral numbness, tingling, muscle aches and spasms. According to postoperative monitoring of parathyroid hormone, all of patients had no permanent hypofunction of the parathyroid gland. Neurotoxic effects and other serious side effects were not observed in all patients. CONCLUSIONIntravenous low-dose methylene blue in thyroidectomy is a safe, easy, and effective technique that facilitates rapid identification of parathyroid gland.

This article is aimed to establish the method of quality standards for highland barley Monascus.Microscopic and TLC were adopted to identify Araliataibaiensis. Referring the relevant method in Chinese Pharmacopoeia (2010 edition) for the determination of its moisture, total ash, acid insoluble ash and extracts,lovastatin in acid and lactone form was determined using high performance liquid chromatography. The characteristics of highland barley Monascus in microscopic and TLC were obvious and specific. The contents in barley red yeast are: water 6.04%-8.78%, total ash 2.15%-2.92%, acid insoluble ash 0.23%-0.29%, water extracts 27.99%-30.17%; alcohol extracts 14.12%-18.51%. The ranges of lovastatin in acid and lactone form are 0.11%-0.29% and 0.02%-0.08%, respectively. The established method is simple, accurate, reliable and duplicable, and can be used to control the quality of highland barley Monascus.

Hepatitis B is a serious infectious disease worldwide, and hepatitis B virus (HBV) is the direct cause of this disease. In recent years, as an essential part of its evolutionary process, HBV mutation has been extensively studied domestically and globally. However, the study on the conserved sequences in HBV sequences is still in its infancy. In this study, we applied multiple EM for motif elicitation (MEME) algorithm to discover HBV motif and proposed a new metric, conservative index (CI), to carry out phylogenetic analysis based on HBV sequences. Then, the constructed phylogenetic tree was subjected to reliability assessment. The results demonstrated that the new metric CI combined with the MEME algorithm can effectively help to discover motifs in HBV sequences and construct a phylogenetic tree based on them and to analyze the evolutionary relationship between HBV sequences; in addition, the possible ancestral sequences of samples may be obtained by conservative analysis. The proposed method is valuable for the exploratory study on large HBV sequence data sets.

The study is aimed to distinguish morphological characteristics of Dalbergiae Lignum collected from crude drug's markets and establish a identification methods and the quality standard for Dalbergiae Lignum. The macroscopic and microscopic features of Dalbergiae Lignum from crude drug's market were observed, analyzed and compared according to Hongmu specification issued by the People's Republic of China in 2000, and by the characteristics recorded in domestic monograph of Mucai Shibie (wood identification). The redwood of Dalbergiae Lignum cut into small pieces as medicinal material are dry heart wood of mahogany (trees from Dalbergia sp.), which characteristics of the small pieces as crude drug are different. There are differences in macroscopic and microscopic features about texture of wood and color, odor, taste, transverse section, radial section, tangential section. The results can provide basis for identification, application and improment of the quality standard of Dalbergiae Lignum as medicinal material.

Objective To observe the effects of levodopa on verbal and spatial working memory in elderly patients with Parkinson's disease (PD).Methods The modified Smith working memory software were applied to study the verbal and spatial working memory in 32 PD patients before and 8 weeks after treatment with levodopa and benserazide hydrochloride tablets.The results of PD patients were compared with those in 32 normal controls matched for age,sex and education.Results The correct rates of phonological verbal and coordinate visuospatial working memory were significantly lower in the PD patients without treatment than in the normal controls (both P＜0.01).The correct rates of semantic verbal and categorical visuospatial working memory had no significant differences between the PD patients without treatment and the normal controls (both P＞0.05).The correct rates of phonological verbal working memory and coordinate visuospatial working memory were significantly higher in the PD patients after administration of levodopa and benserazide tablets than in PD patients without treatment [(88.6±6.5)％ vs.(82.1 ± 6.6)％,(84.2±8.8)％ vs.(75.2±8.9)％,respectively,both P＜0.01],but there were no significant differences in the correct rates of semantic verbal working memory and categorical visuospatial working memory between the above two groups (both P＞0.05).The correct rates of phonological verbal,semantic verbal,coordinate visuospatial and categorical visuospatial working memory were negatively correlated with the course of disease,and had no correlations with age and the degree of education.Conclusions Levodopa can improve the functions of phonological verbal working memory and the coordinate visuospatial working memory,but has no effect on the semantic verbal working memory and the categorical visuospatial working memory.It is postulated that dopamine replacement therapy may have double dissociable effects on the different working memories.

Objective To analyze the long?term efficacy of intensity?modulated radiotherapy (IMRT) with or without chemotherapy in treatment of 454 patients with nasopharyngeal carcinoma (NPC) and its influencing factors. Methods A retrospective analysis was performed on the clinical data of 454 patients with non?metastatic NPC who received IMRT with or without chemotherapy in our center from 2007 to 2012. Prescribed doses of 69. 96?73. 92 Gy in 33 fractions, 69. 96 Gy in 33 fractions, 60. 06 Gy in 33 fractions, and 50. 96 Gy in 28 fractions were applied to nasopharyngeal gross tumor volume, cervical metastatic lymph nodes, high?risk drainage area, and low?risk drainage area, respectively. In all patients, 438 received induction chemotherapy, 420 concurrent chemotherapy, and 216 adjuvant chemotherapy, most of which were based on cisplatin and taxol. The Kaplan?Meier method was used for calculating survival rates and the log?rank test was used for survival difference analysis and univariate prognostic analysis. The Cox model was used for the multivariate prognostic analysis. Results The 3?year sample size was 210. The 3?year overall survival ( OS ) , local recurrence?free survival, nodal relapse?free survival, progression?free survival, and distant metastasis?free survival ( DMFS) rates were 88. 1%, 91. 0%, 90. 7%, 80. 5%, and 85. 1%, respectively. Age, T stage, and N stage were influencing factors for the OS rate ( P=0. 011;P=0. 005;P=0. 033);T stage and N stage were influencing factors for the disease progression?free survival ( P=0. 017;P=0. 005) and DMFS ( P=0. 012;P=0. 019) . The grade≥3 acute and late adverse reactions included hematological toxicity , oral mucositis , xerostomia , dysphagia , and brain injury . Conclusions IMRT promotes the long?term survival rates in patients with NPC. The distant metastasis is the major reason for treatment failure. The adverse reactions induced by IMRT combined with chemotherapy are tolerable.
