AIMTo elevate the encapsulation efficiency, decrease the burst release and improve the release of protein entrapped in poly (lactic-co-glycolic acid) (PLGA) microspheres. The bovine serum albumin (BSA) composite microspheres of alginate-chitosan-PLGA were prepared and the release characteristics of BSA from this composite microspheres were studied.
METHODSThe much smaller calcium alginate microcapsules were first prepared by a modified emulsification method in an isopropyl alcohol-washed way and coated with chitosan, then the alginate-chitosan microcapsules were further entrapped in PLGA to form the composite microspheres. The protein concentration was determined using a BCA protein assay kit. The release profiles were changed with various formulation factors.
RESULTSThe average diameter of the composite microcapsules was about 30 microm. Comparing with 60% to 70% of the conventional PLGA microspheres, the average encapsulation efficiency was more than 80%, and the burst releases in phosphate buffer solution of the composite microspheres decreased from 40% and 50% to 25% and further to 5% in saline solution.
CONCLUSIONThe novel composite microspheres were prepared, the drug encapsulation efficiency increased and the burst release decreased. The desired release profiles could be obtained by regulating the ratios of PLG and PLA in the composite microspheres.

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.

To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.

OBJECTIVE:
Aimed to analyse the clinical features of the patients with sphenoid sinus mucocele, achieve earlier diagnosis and more timely intervention and decrease the occurrence of misdiagnoses.
METHOD:
A retrospective study was first conducted in patients with sphenoid sinus mucoele treated in Xiangya hospital from Jan 2000 to Jan 2015. Then literature reports on this disease were collected and analyzed from China National Knowledge Infrastructure (CNKI) and Wan Fang database.
RESULT:
We collected 82 patients with sphenoid sinus mucocele treated in Xiangya hospital. There were 52 patients presented with headache, 31 patients presented with visual impairment, 10 patients presented with cranial nerve palsy, 2 patients presented with exophthalmos, 15 patients presented with nasal symptoms, and 5 patients with no obvious symptoms. There was no significant difference for symptoms distribution between male and female patients (P > 0.05). Among 45 patients with headache as first symptom and 10 patients with ethmoid sinus mucocele, there were 18 patients and 8 patients subsequently suffering from visual impairment, respectively. We also collected 161 patients in literature except for enrolling, the 82 patients treated in Xiangya hospital, and found that headache was the most common symptom, followed by visual impairment, in the two independent cohorts.
CONCLUSION
To the best of our knowledge, this is the study of maximum sample for sphenoid sinus mucocele in China. Headache and visual impairment are the most common symptoms for sphenoid sinus mucocele. Surgical treatment should be early performed when the desease accompanied with headache or ethmoid sinus mucocele, to avoid other complications such as visual impairment and even blindness.
