Objective To introduce an improved extraction method of prefrontal cortical and striatal synaptosomes from SHR rat. Methods Synaptosomes were prepared from SHR rat brain tissue by Percoll density gradient centrifugation.Transmission electron microscopy was used to assess the morphology and structural integrity of the synaptosomes.Results The obtained synaptosomes showed oval structures surrounded by an intact membrane.Presynaptic components contained one or more mitochondria and a large number of synaptic vesicles.The synaptic clefts were clearly visible, and prominent part of the characteristic compact structure was clear, complete and with higher electron-density. The synaptosome presynaptic membrane, synaptic cleft, and postsynaptic membrane were well preserved, and the synaptosomes were densely distributed, showing typical morphological characteristics of synaptosomes.Conclusions The results of our study improved the traditional preparation method and provide a less time-consuming, highly productive protocol for preparation of structurally typical and intact synaptosomes, suitable for further research on neuroscience and neurological diseases.

Objective To investigate the relationship between the expression of Fascin and breast cancer prognosis. Methods Paraffin sections of breast cancer from 110 patients were investigated by immunohostochemistry with monoclonal anti-fascin antibody. Data of the Fascin expression and clinicopathological variables were analyzed for disease-free survival(DFS)and overall survival(OS)by Kaplan-miere and cox model. Results The expression of Fascin was significantly associated with ER negative,PR negative and lymph node metastasis,but not with age,HER2 status and tumor size. The patients with positive expression of Fascin had shorter disease free survival time than those without Fascin expression. Conclusion High expression of Fascin is associated with poor prognosis in breast cancer. Fascin is an independent prognostic indicator of disease-free survival time.

Objective To investigate the diagnostic value of PIgP/SC in diagnosis of primary hepatic cancer.Methods 58 patients with primary hepatic cancer,60 patients with liver cirrhosis and 60 healthy volunteers were studied.4 ml fasting venous blood was collected from all subjects.Serum level of AFP was detected with electrochemical chemiluminescence immunoassay system and plasma PIgR/SC level was detected by ELISA method.The level of PIgR/SC and AFP was detected at one week after surgical resection in patients with hepatic cancer.Results The levels of AFP and PIgR/SC in the three groups were significantly different (P＜0.01),and PIgR/SC was higher than that in patients with cirrhosis and volunteers (P＜0.01).There was no significant difference between patients with liver cirrhosis and liver cirrhosis(P＞0.05).AFP was higher in patients with HCC than patients with cirrhosis and volunteers.AFP was higher in patients with cirrhosis than volunteers,and the difference was statistically significant(P＜0.01).Sensitivity of PIgR/SC and AFP was 89.3％ and 54.8％,specificity was 84.6％ and 91％,Youden index was 0.751 and 0.458,AUC was 0.920 and 0.761,respectively.There was significant difference in AUC (Z=3.251,P＜0.05) of the two detection indexes for detection of primary hepatic cancer.Conclusion The value of PIgR/SC in diagnosis of primary liver cancer may by higher than that of AFP.

Objective To evaluate the safety of morphine hydrochloride injection. Methods Ear verin injection was used to evaluate the vascular irritation using the comparison of left side with right side in rabbits. Quadriceps femoris injection was used to evaluate the muscle irritation using the comparison of left side with right side in rabbits. Guinea pigs were intravenously injected with morphine hydrochloride injection at a dose of 2.8 mg·kg-1 once daily 3 times, stimulation was performed on 14 d after the last sensitization and the booster dose was 2 times the sensitization dose. The allergic reactions were observed. The different concentrations of morphine hydrochloride injection were placed in 2％ rabbit erythrocyte suspension, and then the hemolyzation and agglutination were observed. Results There were no significant vascular or muscular irritation and injury effects of morphine hydrochloride injection in rabbits. There were no evidenceof hemolyzation and agglutination in rabbit erythrocytes in vitro. No allergic reactions on guinea pigs in vivo were observed. Conclusion After treatment of morphine hydrochloride injection, neither obvious vascular /muscle stimulation or sensitization, nor hemolyzation or agglutination appeared in rabbits. The research results provide basic reference for the clinical rational and safe application of morphine hydrochloride injection.

Objective To analyze the differences in immune system between Npc1 gene mutant (Npc1-/ -) and wild-type (Npc1+/ +) mice for better understanding the pathogenesis of Niemann-Pick disease type C1 (NPC1) from an immunological perspective and providing reference for NPC1 treatment in clinic.Methods Body, thymus and spleen weight of Npc1-/ -and Npc1+/ + mice aged (14±2) days, (42±2) days and (63±2) days (Day14±2 , Day42±2 and Day63±2 ) were recorded and the associated organ index were calcu-lated. White blood cell count in peripheral blood of mice aged Day42±2 was examined by routine blood test. Expression of cytokines at mRNA level in mouse peripheral blood was detected by qPCR. Percentages of CD4+, CD8+ and CD19+ lymphocytes in peripheral blood and spleen of mice aged Day42±2 were measured by flow cytometry. Apoptosis and senescence of spleen in mice aged Day63±2 were examined by immunofluores-cence and β-galactosidase staining. Results Compared with Npc1+/ + mice, there was no significant differ-ence in the weight of spleen and thymus in Npc1-/ - mice aged Day14±2; the weight of spleen in Npc1-/ - mice aged Day42±2 significantly increased, but the weight of thymus showed a significant decrease; furthermore, both the weight of spleen and thymus in Npc1-/ - mice aged Day63±2 significantly decreased; and the body weight of Npc1-/ - mice of each age group significantly decreased. Moreover, compared with Npc1+/ + mice, the absolute number of lymphocytes in the peripheral blood of Npc1-/ - mice aged Day42±2 showed no signifi-cant difference, but the percentage in whole white blood cells significantly decreased due to the significantly increased neutrophils. Expression of cytokines ( IL-1, IL-2, IFN-γ, TNF-α, IL-4, granzyme A and granzyme B) at mRNA level in the peripheral blood leukocytes of Npc1-/ - mice aged Day42±2 was abnormal as compared with that in Npc1+/ + mice. The number of T (CD4+ and CD8+) lymphocytes in Npc1-/ - mice aged Day42±2 significantly decreased, while the number of B (CD19+) lymphocytes increased significantly as com-pared with those in the Npc1+/ + mice. Compared with Npc1+/ + mice, apoptosis and senescence of the spleen in Npc1-/ - mice aged Day63±2 aggravated significantly. Conclusion The abnormal lipid metabolism triggered by Npc1 gene mutation causes severe immune dysfunction in Npc1-/ - mice. Therefore, immune dysfunction should be taken into full consideration when treating patients with NPC1, which might help improve the life quality and prolong the survival time.

Complementary and alternative medicine (CAM) describes a broad category of practices and treatments for the prevention or treatment of disease outside the realm of conventional medicine. CAM is widely used in the treatment of allergic rhinitis, acute and chronic rhinosinusitis. This article summarizes a variety of CAM and the efficacy in the treatment of rhinitis and sinusitis, with the purpose of increasing people′s awareness of CAM and enriching the treatment of rhinitis and sinusitis, so that patients can benefit from it.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.
