Alliinase is immobilized on pre-activated chitosan microspheres by glutaraldehyde.The optimum immobilization conditions are as follows: glutaraldehyde concentration is 4%,alliinase concentration 20.2U,immobilization time 2h.For immobilized alliinase,the highest activity was allowed at pH 7.0 and temperature 35℃,and the Michaelis constant(Km)was disclosed to be 7.9mmol/L by Lineweaver-Burk plot,and after 10 times reuses the immobilized alliinase lost no more than 10% activity.

A total of 1140 medical workers from 8 public hospitals of secondary and tertiary levels in Anhui were surveyed with questionnaire. Their knowledge of the reform, acknowledgement of key points of the reform, desire of participating in the reform and other factors that may influence the reform were investigated as categorized by their hospital, position, title and age. This study comes up with such recommendations as reinforcing communications on public hospital reform, reforming the compensation mechanism to clarify government responsibilities, probing into a better model for multi-institution practice of certified physicians, and encouraging private capital to participate in medical service while ensuring its non-profit nature, and improving the performance appraisal mechanism to ensure incentives of medical workers. These recommendations aim to enable the health administrators in their decision making.

Human violent behavior is a complex behavior which is influenced by genetic and environmental factors. There is a trend in investigating the mechanism of violent behavior by using the genetic methods. This article reviews several candidate genes and advances in epigenetics which are associated with violent behavior. The prospects and significance of violent behavior research from the view of gene polymorphism and epigenetics are also discussed.

Nuclear magnetic resonance (1H-NMR) fingerprint of Rhodiola rosea medicinal materials was established, and used to distinguish the quality of raw materials from different sources. Pulse sequence for water peak inhibition was employed to acquire 1H-NMR spectra with the temperature at 298 K and spectrometer frequency of 400.13 MHz. Through subsection integral method, the obtained NMR data was subjected to similarity analysis and principal component analysis (PCA). 10 batches raw materials of Rhodiola rosea from different origins were successfully distinguished by PCA. The statistical results indicated that rhodiola glucoside, butyl alcohol, maleic acid and alanine were the main differential ingredients. This method provides an auxiliary method of Chinese quality approach to evaluate the quality of Rhodiola crenulata without using natural reference substances.

Anxiety disorder is one of the most common mental disorders and seriously impairs the physical and mental health of patients. Due to the efficacy of acupuncture for tranquilization, acupuncture displays its unique advantage on the treatment of anxiety disorder, but the relevant biological mechanism has not been elaborated. The modern medicine study has proved that the heart and brain have their own independent natriuretic peptide (NP) system. The dysfunction of ANP and its receptor are closely related to the occurrence of anxiety disorder. The ANP acts on anti-anxiety. Hence, focusing on the three aspects, named the anti-anxiety effect of acupuncture based on its tranquilizing effect, the anti-anxiety effect of ANP and the positive regulation of acupuncture on NP, the mechanism on ANP and its receptor was explored in anti-anxiety with acupuncture based on tranquilizing effect, and the idea was put forward on that the anti-anxiety effect of acupuncture was possibly based on its action of tranquilization through regulating the ANP and its receptor. As a result, it is expected to provide the theoretic support for the mechanism study on anti-anxiety with acupuncture based on its tranquilizing effect.

Objective To compare proprotein convertase subtilisin/kexin type 9 (PCSK9) levels between premenopausal and postmenopausal women,and to investigate the relationship between serum PCSK9 and metabolic factors.Methods Totally 515 women were enrolled from the study on diabetes of prediction,prevention,and intervention in Nanjing in 2009.Survey,physical examinations,and determination of related metabolic indexes were performed.Serum PCSK9 level was measured by sandwich ELISA.Results Serum PCSK9 level was positively correlated with low density lipoprotein-cholesterol (LDL-C),total cholesterol (TC),triglyceride,fasting plasma glucose,body mass index,waist-hip ratio,and age in women (all P<0.01).PCSK9 level was significantly lower in premenopausal women than that in postmenopausal women [(58.18 ± 25.44 vs 80.91 ± 33.74) ng/ml,P <0.01].Conclusion Higher level of PCSK9 exists in postmenopausal women compared with premenopausal women.The level of PCSK9 is closely correlated with age,TC,and LDL-C.

After 28 foreign species of AM fungi were inoculated in sterilized soil, the effects of the AM mycorrhizal colonization and the medicine quality of Paris polyphylla var. yunnanensis were observed by combination of inoculation test in pot at room temperature and instrumental analysis. The results showed that, compared with control group (CK), the inoculation of foreign AM fungi in the soil influenced the spore density, mycorrhizal infection rate, and colonization intensity of AM fungi in root system of P. polyphylla var. yunnanensis. The inoculation of foreign AM fungi enhanced the mycorrhiza viability of P. polyphylla var. yunnanensis by increasing the activity of succinic dehydrogenase (SDH) and alkaline phosphatase (ALP) in intraradical hyphae. The content of single steroid saponin in rhizome of P. polyphylla var. yunnanensis showed variation after P. polyphylla var. yunnanensis was inoculated by different foreign species of AM fungi, which was beneficial for increasing the medicine quality; however, the kinds of steroid saponin showed no difference. In a degree, there was a selectivity of symbiosis between P. polyphylla var. yunnanensis and foreign AM fungi. And we found that the Claroideoglomus claroideum and Racocetra coralloidea were best foreign AM fungi species for cultivating P. polyphylla var. yunnanensis under field condition.

Objective To study the effects of cluster nursing intervention on dysuria in hospitalized patients after renal biopsy. Methods A total of 106 hospitalized patients undergoing renal biopsy during April. 2016 to September. 2016 were divided into control group (50 cases) and experimental group (56 cases) by random number table method. The control group were implemented with traditional methods of care and the experimental group were implemented with cluster nursing intervention.The incidence of dysuria, first average urination time and post-operative urination pattern were compared between two groups. Results The incidence of dysuria in the experimental group was 10.7%(6/56), which was significantly lower than 28.0% (14/50) of the control group (χ2=5.156, P<0.05).The first average urination time of experimental group was (2.95±1.17) hours, which was lower than (5.04±2.27) hours of the control group (t =5.401, P<0.05). The proportion of patients with post-operative self-urination in the experimental group was significantly higher than that in the control group (χ2=6.152, P<0.05). Conclusions Cluster nursing intervention can reduce the incidence of dysuria, shorten the first average urination time, promote post-operative self-urination of patients after renel biopsy and enhance comfort.
