Objective To evaluate the effect of individualized diet nursing on nasogastric gavage-indueced complications after operations on laryngeal cancer? Methods Sixty patients having undergone surgical operation on laryngeal cancer were randomly divided into experiment group and control group in equal number? The control group received nutritional support by conventional enteral nutrition and the experiment group was managed by individualized diet nursing with nasogastric feeding? On days 3 and 10 after operation,the two groups were compared in terms of body constitution,results of experimental tests and complications?Result Compared to the control group,the experiment group showed no significant difference in terms of body constitution and results of experimental tests(P > 0?05)but significantly lower rate of complications on days 3 and 10(P < 0?05)? Conclusion The individualized diet nursing for laryngeal cancer patients may ensure their needs for nutrition,meanwhile reduce the incidences of complications from enteral nutrition,and thus promote their recovery?

Objective To prepare optimization of palonosetron hydrochloride oral disintegrating tablets by orthogonal test. Methods Palonosetron hydrochloride oral disintegrating tablets were prepared with direct compression process.The content of pal-onosetron hydrochloride was determined by HPLC.The formulation was optimized with disintegration time as evaluation indices. Results The optimal formulation(60 mg/tablet)was as follows:L-HPC 12%,mannitol∶SMCC= 2∶1,magnesium stearate 2%, stevia glycosides 3%.The oral disintegrating tablets showed dine appearance and tested better;the disintegration time was 12 sec-onds;the tablets featured a hardness of 3 kg;4 min dissolution rate was 99%.Conclusion The preparation method is simple and reasonable,and the tablets can disintegrate rapidly.

ObjectiveTo compare therapeutic effects of the bone-guided tissue regeneration in combination with a composite bovine-derived xenograft versus flap surgery only on intra-bony defects in elderly patients with periodontal disease. MethodsThirty elderly patients with periodontal disease were randomly divided into two groups. One group was treated by the bone-guided tissue regeneration in combination with a composite bovine-derived xenograft (experimental group). The other group was treated by flap surgery only (control group). Probing depth (PD)and clinical attachment level (AL) were determined before surgery and six months after treatment in two groups. The change of bone amount was also determined before surgery and six months after treatment through computer-assisted densitometric image analysis(CADIA). ResultsThe changes of PD and CADIA were (3.8+1.7)mm, (20. 3+11.1)g/mm2 in experimental group and were (2.5+1.1)mm, (9.4+8. 6)g/mm2 in control group. The differences between two groups were significant (P.＜0. 05). The change of AL was (3.5+ 1.6)mm in experimental group, compared with control group(2. 3 1.7)mm, which showed more obvious regeneration of alveolar bone (P＜ 0. 01). ConclusionsGuided tissue regeneration in combination with a composite bovine-derived xenograft appears to be more effective than flap surgery only for intra-bony defects in elderly patients with periodontal disease.

Objective:To explore the role of 6-CYANO-2,3-DIHYDROXY-7-NITROQUIN OXALINE (CNQX) in different types of synapse secretion.Methods:The spontaneous mEPSCs and eEPSCs at different extracellular concentrations of CNQX in cultured cortical or hippocampal neurons were recorded respectively.Results:The half inhibitory concentration (IC50) of CNQX in evoked neurotransmitter release was significantly higher than that of spontaneous release,indicating that the spontaneous neurotransmitter release was more sensitive to CNQX.No apparent difference was observed between cortical and hippocampal cells,suggesting that the blocking effect of CNQX was similar in different brain regions.Conclusion:CNQX might have differential regulating mechanisms between excitatory spontaneous and evoked neurotransmitter release,but without brain regions specificity.

Objective:To optimize the water extraction process of traditional Chinese medicine ( TMC) Qubai granule. Methods:The orthogonal test was used to study four influencing factors including water amount, soaking time, extraction time and extraction times with dry extract yielding rate and the content of ferulic acid as the evaluation indices. Results:The optimum extraction process was as follows:A2 B1 C2 D2 , namely adding 10-fold amount of water, without soaking in advance, extracting twice with 2 h for each time. Con-clusion:The process is simple, stable and reproducible, which provides basis for the industrial production.

Objective To systematically evaluate the health status and intervention measures in the US Armed Forces, and to provide reference for the development of health promotion strategies in our army.Methods The PubMed, Medline, Springer, Elservier, HighWire and CNKI Database were searched electronically, with assigned search strategy for American military health status and intervention measures published from Jan.1997 to Dec.2015.Results There were 25 of pieces literature about training injury, low back pain, posttraumatic stress disorder, depression and cardiovascular disease that were screened.Conclusion The main health problems facing the US Armed Forces and the focus of the intervention measures involved training injuries, low back pain, mental illness and cardiovascular disease.Protection of military health is shifting from the single disease prevention to diversified comprehensive maintenance in the new era.

Objective To describe an intelligent three-dimensional technique for automatic visualization of the fetal cranial mid-sagittal view to allow for the differential diagnosis of fetal midline anomalies.Methods Two hundred and twenty pregnant women with singleton pregnancies were imaged to display the mid-sagittal view of fetal head using a new 3D program (Smart MSP) developed by our team.Results The mid-sagittal view of the fetal head was successfully visualized in 190 normal cases (95％) and 18 abnormal cases (90％) by Smart MSP program.The total successful rate was 94.5％ (208/220).Conclusions Smart MSP is a novel and feasible method for the automatic visualization of fetal cranial midsagittal plane and may become a potential tool for routinely screening the fetal midline anomalies.

Objective:To investigate the relationship between herpesviridae and malignant or benign laryngeal diseases.Method:128 paraffin-embedded laryngeal squamous cell carcinoma and laryngeal epithelium hyperplastic lesions were detected by polymerase chain reaction (PCR) and PCR-ISH for herpesviridae. Result:HSV-1 was detected in 10 cases by PCR,among them 3 were laryngeal squamous cell carcinoma (LSCC),1 was carcinoma in situ(CIS),4 were laryngeal polyps and 2 were laryngeal keratosis. Except 1 LSCC and 1 CIS, 8 of 10 cases were positive while detected by PCR-ISH. In benign diseases, signals were shown from basal layer to superficial cell; in malignant lesions, the signals were scattered in the diseases.Conclusion:Most of laryngeal diseases were not related to herpesviridae, but HSV-1 may acts as initiator in the development of a few cases.

Objective To prepare Exosomes secreted by mouse hepatoma cell (H_(22)) and heat stressed Exosomes (HS-Exo) derived from heat stress-treated mouse hepatoma cell (H_(22)), in order to study the possible anti-tumor immune mechanism. Methods Exosomes and HS-Exo were purified by serial ultracentrifugation and sucrose density gradiant centrifugation, and were observed and identified by electron microscope. The components and production of the protein and the effects of the host immune response against hepatocellular carcinoma of HS-Exo were observed by using Exosomes as the control. Their immunological factors were detected by Western blot. Lymphocyte proliferation and specific cytotoxic activity of mouse splenic cells were determined by MTT. CD4~+ and CD8~+ lymphocytes infiltration in mouse tumor tissues immunized by both were analysed by immunohistochemical staining. Results HS-Exo was similar in morphology to the Exosomes, the important immune-ralated protein expressed in HS-Exo was increased (P<0.05). HS-Exo immunized mouse group showed more effective inhibition of tumor growth, better-induced lymphocyte proliferation,more significantly enhanced the cytotoxic activity of spleen lymphocytes, as well as a more prominent role in tumor therapy than Exosomes immunized mouse control group (P<0.05). Conclusions Heat stress treatment method for the preparation of HS-Exo was feasible. HS-Exo had a stronger role in the immuneactivity and tumor treatment than control Exosomes.
