At the boundary between pharmacognosy and molecular biology, molecular pharmacognosy has developed as a new borderline discipline. This paper reviews the methods, application, and prospect of molecular pharmacognosy. DNA marker is one of genetic markers and some molecular marker methods which have been successfully used for genetic diversity identification and new medicinal resources development. Recombinant DNA technology provides a powerful tool that enables scientists to engineer DNA sequences. Gene chip technique could be used in determination of gene expression profiles, analyses of polymorphisms, construction of genomic library, analysis of mapping, and sequencing by hybridization. Using the methods and theory of molecular biology and pharmacognosy, molecular pharmacognosy represents an extremely prospective branch of pharmacognosy and focuses on the study of systemic growth of medicinal plants, identification and evaluation of germplasm resources, plant metabolomics and production of active compounds. Furthermore, the great breakthrough of molecular pharmacognosy could be anticipated on DNA fingerprint analysis, cultivar improvement, DNA identification, and a global DNA barcoding system in the future.

Objective To grasp the current situation and trend of health personnel development in public TCM hospitals through the analysis of health personnel statistics data of public TCM hospitals in China; To provide decision-making references for management departments. Methods Data were from the National Health and Family Planning Commission Statistical Information Center. This article analyzed staff number, the average speed of development, the average annual growth rate, health staff age, academic qualifications and job titles and other indicators of TCM public hospitals during 2010-2015. Results From 2010 to 2015, there was an annual increasing tendency of the number of TCM health personnel, and the average annual growth rate was 5.9％, but the growth of the percentage of the TCM health personnel to the total health personnel was only 0.3％. In 2015, the proportion of TCM health personnel was less than 50％; the doctor-to-nurse ratio was 1:1.18; the educational level of postgraduate and undergraduate were 14.0％ and 48.0％ respectively, less than the average level of national hospitals. Conclusion From 2010 to 2015, there is an increasing tendency of the TCM health personnel of public TCM hospitals, but the proportion of TCM health personnel is low. The doctor-to-nurse ratio is reasonable gradually, but there is still a gap compared with the average level of the national hospitals. The average age of technical health personnel tends to be younger. The proportion of high educational level health personnel is increasing, but the proportion of senior technical position is reduced. The management departments should take appropriate measures to promote the rational allocation of human resources and development of TCM hospitals.

BACKGROUND:cAMP response element binding protein (CREB) is a key protein of memory, which is closely related to long-term memory. It wil provide a new way for the treatment of hypoxic ischemic brain damage (HIBD) to study the effects of dental pulp stem cel s transplantation on the long-term behavior and CREB protein via the lateral ventricle in neonatal HIBD rats. OBJECTIVE:To observe the changes in long-term behavior and CREB protein expression in neonatal HIBD rats after human dental pulp stem cel transplantation, thereby providing scientific evidence for clinical treatment of neonatal HIBD. METHODS:Thirty-six healthy 7-day-old Sprague-Dawley rats were randomly divided into normal, HIBD and cel transplantation group. The hypoxic ischemic brain damage models were established in the brain damage and cel transplantation groups. Twenty-four hours after HIBD, human dental pulp stem cel s were injected into the left lateral cerebral ventricle of rats in the cel transplantation group, total y 3×106 living cel s. Equal volume of normal saline was injected into the left lateral cerebral ventricle of rats in the normal control and HIBD groups. RESULTS AND CONCLUSION:The average time to seek water, the average escape latency and escape distance of the human dental pulp stem cel s group were significantly shorter than those of hypoxic ischemic brain injury group (P<0.01), but longer than those in the normal group (P<0.01). Nissl staining showed that the cel s in the hippocampal CA1 region in human dental pulp stem cel s group were more regular, the number of cel s was significantly higher than that of hypoxic ischemic brain injury group, but stil significantly less than that in the normal group (P<0.05). Immunohistochemical staining results showed that the number of CREB positive cel s in human dental pulp stem cel s group was significantly higher than those in HIBD group, but stil significantly less than those in the normal group (P<0.01). It is suggested that human dental pulp stem cel s transplantation could promote the expression of CREB protein in the hippocampal CA1 region, to improve the long-term learning and memory ability of hypoxic ischemic neonatal rats, and thus repair HIBD.

Objective To evaluate the clinical efficacy and adverse effects of brucea javanica oil emulsion combined with DP chemotherapy in treating advanced non-small-cell lung cancer.Methods Totally 48 patients with advanced non-small-cell lung cancer were divided into two groups randomly by mechanical sampling method.Twenty-four cases in treatment group were treated by brucea javanica oil emulsion combined with DP chemotherapy, while 24 cases in control group were treated by DP chemotherapy only.The clinical effects were evaluated after treatment of two cycles.Results The short-term effective rate was 54.2% (13/24) in treatment group and 45.8% (11/24) in control group, and there was no significant difference between two groups ( χ2 = 0.333, P = 0.564).The rate of increased and stable life quality was 87.5%(21/24) in treatment group and 58.3%(14/24) in control group,and there was significant difference between two groups (χ2 = 5.169,P = 0.023).The rate of increased and stable weight was 79.2% (19/24) in treatment group and 45.8%( 11/24) in control group, and there was significant difference between two groups (χ2 = 5.689,P = 0.017).The incidence of nausea or vomiting was 45.8% (11/24) in treatment group and 41.7%( 10/24 ) in control group, and there was no significant difference between two groups (χ2 = 0.085, P = 0.771 ).Compared with those in control group, patients in treatment group had less adverse effects in decreasing of peripheral blood leucocytes and showed better immune function.Conclusion Brucea javanica oil emulsion combined with DP chemotherapy in treating advanced non-small-cell lung cancer has good clinical effect, especially enhances the quality of life, improves immune function and decreases the adverse effects of chemotherapy.
