This study aims to develop a method for determination of beta-elemene, curcumol, germacrone and neocurdione in the volatile oil of Curcuma phaeocaulis, and to provide the basis of the quality control method for the volatile oil of C. phaeocaulis and the related preparations. Based on GC-MS, the 4 main compounds were simultaneously determined, with the internal standard n-tridecane. The Agilent 19091S-433 column (0.25 microm x 250 microm x 30 m) was adopted at the temperature of 250 degrees C, the programmed temperature method (60 degrees C for 1 min, 5 degrees C x min x to 110 degrees C for 5 min, 1 degrees C x min(-1) to 140 degrees C, 5 degrees C x min(-1) to 160 degrees C, 10 degrees C x min(-1) to 240 degrees C) was used. Helium gas was used as the carrier gas at a constant flow rat of 1 mL x min(-1), with an injection volume of 1 RL. Mass spectra were taken at 70 eV; the ion-source temperature was 200 degrees C. The relation time and character acteristic ions for each target compound were determined by full scan mode and SIM, and m/z 85.1, 93.1, 121.1, 107.1 and 180.1 were the detection ions of n-tridecane, beta-elemene, curcumol, germacrone and neocurdione. As a result, beta-elemene, curcumol, germacrone and neocurdione were all detected with good separation. They were all in a good linear relationship within each concentration scope. The average recovery rates were in the range of 98.2%-101%. So, the method can be used to control the quality of the volatile of C. phaeocaulis Val. and the preparations related.

Objective To explore the role of coping styles and personalities in the etiology of Graves' disease (GD). Methods All participants (581 patients and 800 normal controls) completed the general information questionnaires,trait coping style questionnaires(TCSQ) and eysenck personality questionnaires revised,short scale for Chinese(EPQ-RSC). Basic characteristics of all subjects were documented, and logistic regression analysis was used to analyze the role of coping styles and personality in etiology of GD. Results The negative coping style(OR = 1.068,P=0.000) ,concealing character(OR = 1. 121, P=0.000) and internal and external personality (OR = 1.089, P = 0.005) neurotic personality (OR > 1.000, P< 0.05) were risk factors of GD( OR = 1. 162, P = 0.000) ,positive coping style was protective factor of GD( OR < 1.000, P<0.05). Conclusion Positive coping style and specific personality adjustment can prevent effectively onset of GD.

The quality markers (Q-markers) of traditional Chinese medicine (TCM) have become a topic of interest in TCM research in recent years. Nonetheless, there is still no consensus on how to scientifically characterize TCM Q-markers. Our study establishes an identification method for TCM Q-markers based on the analytical hierarchy process (AHP) and the entropy weight comprehensive method. By constructing an evaluation system encompassing the target layer, the factor layer and the control layer, AHP can be used to analyze the weight of three core TCM quality attributes, including effectiveness, testability and specificity. Following that, the entropy weight method is employed to analyze the specific indicators for each attribute based on the literature and experimental data. Finally, the comprehensive weight of each index is obtained by combining the two weights, and the comprehensive weight and the specific value of each component is multiplied and summed to obtain the integrated score ranking, and thereby identify the TCM Q-markers. Taking Shaoyao Gancao decoction as an example, the analysis revealed that the top 8 components are as follows: paeoniflorin > quercetin > albiflorin > glycyrrhizic acid > naringenin > liquiritin > oxypaeoniflorin > benzoylpaeoniflorin, and can be identified as Q-markers of Shaoyao Gancao decoction. This study not only provides support for the establishment of quality standards and process quality control of TCM formulae, but also provides innovative ideas and methods for quantitative evaluation and accurate identification of TCM Q-markers.

Objective: To explore the determinants for health-seeking behavior of the residents after cough for more than 3 weeks in Yiwu, Zhejiang Province, in order to provide reference for prevention and control of respiratory diseases. Methods: A multi-stage cluster random sampling method was used to recruit the community residents aged 5 years and above in Yiwu. A face-to-face questionnaire survey was conducted to collect demographic information, features of cough and health-seeking behaviors in the past month. The multivariate logistic regression model was employed to analyze the associated factors for health-seeking behavior after a cough for more than 3 weeks. Results: Among 6 374 residents investigated, 152 cases had a cough for more than 3 weeks in the past month, accounting for 2.48%. They were( 45.00±21.15 ) years old, including 70 ( 46.05% ) males and 82 ( 53.95% ) females. About 58.55% ( 89 ) of them sought medical treatment. The results of multivariate logistic regression analysis showed that females ( OR=2.100, 95%CI: 1.005-4.391 ), middle school education level ( OR=0.406, 95%CI: 0.168-0.983 ), family annual income of 100 000 to 199 999 yuan ( OR=2.993, 95%CI: 1.215-7.373 ) were associated factors for health-seeking behavior after a cough for more than 3 weeks. Conclusion The rate of health-seeking behavior after a cough for more than 3 weeks among the residents in Yiwu is 58.55%, which is associated with gender, education level and income.

Bone turnover is regulated by local concentrations of cytokines such as osteoprotegerin (OPG) and receptor activator of nuclear factor kappaB ligand (RANKL). To explore the in vivo biological function of Opg and the mechanism of osteoporosis due to deficiency of Opg, Opg knockout mice have been generated through homologous recombination. Opg-/- mice exhibit a sharply decrease in bone density and strength as expected. The number of osteoclasts in Opg-/- mice significantly increases. Morphologically, osteoclasts appear more cuboidal in shape in Opg-/- mice than those of wt mice, suggesting that active osteoclastogenesis occurs in the absence of Opg. In consistent with this finding, an increase of osteoblast activity was also observed with accelerated mineral accumulation rate by histomorphometric measurement and elevated serum alkaline phosphatase activity (ALP) in Opg-/- mice. Interestingly, more than 50% of 2-month-old Opg-/- mice manifest medial calcification of aorta with comparable serum concentrations of calcium and phosphorus to wt mice. In conclusion, Opg-/- mice have a high-bone-rurnover type osteoporosis. The aortic calcification in Opg-/- mice is not due to abnormality of calcium and phosphorus metabolism. The mechanism underlying aortic calcification in Opg-/- mice needs to be further investigated.

Objective To improve the level of early detection and treatment of pyonephrosis. Methods This study included 41 cases(17 men and 24 women;mean age,49 years)of pyonephrosis.A variety of examinations,including urinary analysis,blood analysis,kidney nuclear medicine scan,ultrasonog- raphy,intravenous urography(IVU),and CT were used for the early diagnosis of pyonephrosis.Pereutaneous nephrostomy(PCN)drainage was done for the interim management of pyonephrosis,then phase 2 operation was performed in 28 cases.The double-J tube was placed in ureter by ureteroscope for drainage,and then phase 2 operation was done in 2 cases.Emergency operation was done in 10 cases.The remaining 1 case un- derwent ESWL after anti-infective therapy.Results Definite diagnosis of pyonephrosis before operation was made by invasive examinations in 31 cases(75.6%),and by percutaneous drainage in 4 cases;the other 6 cases were detected during operation.Only 6 cases(14.6%)underwent nephrectomy;the other 35 cases (85.4%)underwent kidney-sparing operation.Follow-up of 3 months to 9 years was available in 37 cases. No nephrectomy was needed in 33 cases with spared kidney.Serum creatinine was normal in the 4 cases un- dergoing nephrectomy.Conclusions The key to the treatment of pyonephrosis by kidney-sparing surgery is early diagnosis,timely drainage and relief of obstruction.Ultrasonography plays an important role in the early diagnosis of pyonephrosis,and CT has a high sensibility in the diagnosis.Pereutaneons nephrolithotomy (PCNL)secondary to drainage through pereutaneous nephrostomy was beneficial to the patients with kidney stones or upper ureter stones.

OBJECTIVETo investigate the feasibility of utilizing self-designed score system for lower lumbar vertebral burst fractures to select surgical approach.

METHODSFrom January 2006 to December 2011, the clinical data of 56 patients with lower lumbar vertebra burst fractures who underwent surgical treatment were retrospectively analyzed. There were 42 males and 14 females with an average age of 43.1 years old (ranged, 19 to 65). Causes of injury included falling down (40 cases), traffic accidents (12 cases), and crashing injury by heavy objects(4 cases). Injury site was L3 in 37 cases, L4 in 16 cases, and L5 in 3 cases. According to the AO classification, 17 cases were type A3.1, 14 cases were type A3.2, 25 cases were type A3.3. According to Frankel grade of nerous function, 2 cases were grade B, 5 cases were grade C, 9 cases were grade D and 40 cases were grade E. Surgical methods and approaches were chosen based on the comprehensive evaluation of AO classification, condition of posterior column injury and spinal canal encroachment. Surgical methods and approaches included trans-vertebra fixation (15 cases), intra-vertebra pedicle screw fixation (21 cases), combination of anterior and posterior approaches (11 cases), one-stage posterior approaches (9 cases). Cobb angles, restorations of the affected vertebral anterior border height, and conditions of spinal canal encroachment were compared before and after surgery. Conditions of bone graft fusion and internal fixation (if bending, loosening or breakage existed) were observed. Spinal cord functions were assessed according to Frankel grade. Localized pain and working status of patients were also assessed at the last follow-up.

RESULTSNo incision infection was found and no spinal nerve symptoms improved in all of 56 patients. All patients were followed up for 12 to 60 months with a mean of 28.5 months, without internal fixation loosening or breakage. There was significant differences in Cobb angle, vertebral anterior border height and recovery of spinal canal encroachment between preoperative and postoperative instantly (P < 0.05), however, there was no significant difference between postoperative instantly and final follow-up (P > 0.05). Thirteen cases obtained fusion by trans-vertebra fixation, 20 cases obtained fusion by intra-vertebra fixation, and 20 cases were treated by the combination of anterior and posterior approaches or one-stage posterior approaches all of patients obtained fusion. Spinal nervous function recovered I to II grade, 1 case was grade C, 3 cases were grade D, 52 cases were grade E. Localized pain was assessed as P1 in 52 cases, P2 in 3 cases, and P3 in 1 case. Working status was classified into W1 in 12 cases, W2 in 39 cases, and W3 in 5 cases.

CONCLUSIONThe lower lumbar vertebra and thoracolumbar junction exhibit different injury characteristics due to variations in anatomy and biomechanics. A comprehensive score of the AO classification, posterior column injury and degree of spinal canal encroachment will guide the selection of surgical method and approach for the treatment of lower lumbar vertebra burst fractures.
