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.

[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.

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 characterize emotional memory impairment in untreated patients with Parkinson' s disease (PD) in the early stages of the disease. Methods Emotional memory tasks using standardized sets of emotional pictures including positive, neutral and negative valence were tested in 33 untreated patients with PD in the early stages and 31 healthy controls matched with age, sex, and education.Results Compared with the healthy adults (13.4 ± 1.4), PD patients had significant loss of negative valence picture memorizing ( 8. 9 ± 1.0; t = - 14. 87, P < 0. 01 ).There was no significant difference between PD patients and normal controls in positive ( 11.8 ± 1.0 vs 12. 4 ± 2. 2 , t = - 0. 95 ) and neutral (7.9 ± 1.4 vs 8.2 ± 1.3, t = - 0. 89) valence picture memorizing ( both P > 0. 05 ). ConclusionThe emotional memory for negative valence pictures is impaired but the emotional memory for positive and neutral is relatively spared in early PD patients without treatment.

Objective A large number of injured earthquake patients were accepted by the hospital whilethe professional surgeons were relatively lack. This article introduced the hospital emergency management in 2008Sichuan Wenchuan Earthquake, China. Method Within 3 days, Central Hospital of Mianyang accepted andtreated over 1000 patients after Wenchuan Earthquake jolted on 12 May 2008,and within 2 weeks, the number ofpatients reached 1500. The hospital carded out emergency management plan: (1) emergency comprehensive treat-ment district was established, which was divided into traumatic surgery district, general surgery district, and gen-eral medical district. Traumatic surgery district is responsible for treating traumatic patients, and most doctors andnurses were in this district. The district also had preview, contamination, operation, isolation, monitoring sec-tions, and the tents were numbered and labeled. General surgery district and general medical district were responsi-ble for patients not from earthquake, and only few doctors and nurses were in the two districts. According to the in-jury degree, all the wounded were classified into acute and severe, moderate and minor injuries, and wore red,yellow and blue label on the wrists, respectively. The name, gender, age and diagnosis of each patient and thename of doctor were written on the label. The infectious patients and non-infectious patients were separated.Results Near 200 operations and near 300 operations were performed at one night and at one day, respectively.Within one week, only 1 patient had the lung infection, and one patient with gangrenous emphysema was effective-ly treated. In-hospital cross infection and epidemic of infection disease didn't happen. Conclusions Emergencymanagement model and mechanism, which referred to the model of the battlefield ambulance, played an importantrole in treating a large number of injured patients.
