The compound Chinese materia medica is the medication pattern of the traditional Chinese medicine for the disease prevention and treatment. The single Chinese materia medica (mostly in decoction pieces) is the prescription composition of the compound Chinese materia medica. The study of the effective substance basis of Chinese materia medica should be based on the chemical compositions of the compound Chinese materia medica as an entry point considering the different status of "Monarch, Minister, Assistant, and Guide" for a certain single Chinese materia medica in the different compound Chinese materia medica while substance basis research of a certain single Chinese materia medica should be a full component analysis as well as both stable and controllable quality. Substance basis research on Chinese materia medica is one of key scientific problems of inheriting, development and innovation of Chinese materia medica.

Objective: To analyze the chemical constituents of the essential oil extracted from the seeds of Myristica fragrans Houtt.(nutmeg) in Indonesia and to provide qualities control scientific foundations.Methods: The essential oil was extracted by steam distillation and separated with GC capillary column.The relative content of every compound was determined by normalization method and the chemical compositions were evaluated by GC-MS.Results: Ninety-three chromatographic peaks were isolated and sixty-one compounds were identified,accounting for 97.62% of the total essential oil in nutmeg.Conclusion: The essential components of nutmeg in Indonesia is monoterpenoids and it's derivatives,accounting for 78.87% of the total essential oil.And phenolic compounds were the secondary composition,accounting for 16.79%.The essential oil contains safrole,which can induce genetoxicity and mutagenicity in animal,and myristicin and elemicin which can induce illusion.So,it must be careful when Myristica fragrans Houtt was used.

As a kind of the plant tissue cultures, hairy root culture is characterized by rapid growth without exogenous hormones source and high yield of secondary metabolites, which attracted the attention of scholars in resent years. This work systematically summarized the research of medicinal plant hairy roots, including the mechanism, current situation of medicinal plant hairy roots, and their applications.

The volatile compounds of trogopterorum feces were collected by using a simultaneous distillation and extraction (SDE) equipment. The chemical composition of the enriched volatile was examined by means of capillary gas chromatography (GC) and combined GC-mass spectrometry (MS). Fifty one constituents of the volatile were preliminarily identified by GC-MS, which amounted to 56.3% of the total peak area. Of these compounds, 33 were further verified by measuring their temperature-programmed retention indexes (TPRI) or retention times. They amounted to 35.7 % of the total peak areas. The main constituents of the volatile are dedecanoic acid (7.00%);alphacedrol (4.41%); pyrazine, tetramethyl-(4. 10%); tetradecanoic acid (3.37%); ethanone, 1-(3-methylphenyl)- (2.53%); benzaldehyde (2.42%); phenol, 2-methoxy-(2.11% ). The compound classes consist of alcohols (10), ketones (8), aldehydes (6), olefines (5), acids (4), and phenols (4).

OBJECTIVETo explore clinical efficacy and key matters for the treatment of femoral intertrochanteric fracture and integrity of lateral trochanteric wall by proximal frmoral nail antirotation (PFNA).

METHODSFrom June 2010 to December 2012,210 femoral intertrochanteric fracture patients treated with PFNA were retrospectively analyzed, including 76 males and 134 females aged from 46 to 96 years old with an average of 71 years old. All fracture were caused by injury and classified to type I (5 cases) type II (16 cases), type III (73 cases) and type IV (116 cases) according to Evans classification. The time of getting out of bed, postoperative complications and displacement of screw blade and fracture healing were observed, Baumgaertner criteria were used to evaluate quality of fracture reduction, Harris criteria were used to evaulate hip joint function.

RESULTSAll incisions were healed at stage I, no complications occurred except incomplete of lateral trochanteric wall patients without reconstruction, other patients could get out of bed with crutches at one week and all patients discharged from hospital at 10 days after operation. One hundred and seventy-eight patients were followed up from 3 to 17 months with an average of 10 months. One case occurred unhealed fracture displacement caused by screw blade cutting, 2 cases occurred screw blade transfomed to proximal and out femoral head, other patients obtained fracture healing at 12 to 16 weeks after operation. According to Baumgaertner criteria, 130 cases obtained good results, 45 cases acceptable, and 3 poor; while 107 cases obtained excellent results, 65 good, 3 good and 3 poor according to Harris score.

CONCLUSIONPFNA with mechanical advantage of intramedullary fixation has advantsges of stable fixation, shorter operation time, minimally invasive. Satisfied clinical effects could obtained by grasping fixation principle, dealing with negative factors in operation. Intraoperative reconstruction for integrity of lateral trochanteric wall could assure stable fixation and earlier get out of bed.

Objective To observe the influence of Bailong Jieyu Granules on quality of life (QOL) of patients with cancer-ralated depression. Methods A prospective and self-control clinical trial was carried out. Sixty seven patients with cancer-ralated depression were chosen and treated with Bailong Jieyu Granules. EORTC QLQ-C30 3.0 scores of patients were assessed before and after the treatment. Results After treatment of Bailong Jieyu Granules, the scores of role function, emotional function and global quality of life were increased, while the scores of fatigue, nausea/vomiting, insomnia and appetite loss were decreased, there were significant differences (P

Purpose　The aim is to establish a simple method to extract superoxide dismutase(SOD) from pig blood red cells.Methods　A combined method-microwave heating and adding Cu2+ into the suspension-was used to extract SOD from the red cells. Results　The undesired proteins were denatured by microwave heating and SOD was partly purificated in comparison with hemolysis. The processing time of the former was much shorter than the latter. Conclusion　A novel cell disruption microwave heating, was a rapid and effective technique for the primary extraction of SOD.
