Objective To study the positions,features and sectional anatomy of the palatovaginal canal and vomerovaginal canal,comparing with CT and MRI findings. Methods The palatovaginal canals in 104 sides and vomerovaginal canals in 60 sides of dry skulls were observed.Three adult cephalic specimens were sliced into celloidin contiguous sections on coronal plane(0.5 mm in thickness) and the results were correlated with the CT studies of 11 patients and MR imaging of a cephalic specimen. Results In dry skulls,the palatovaginal canal displayed as complete canal in 79.8% of the cases,while appeared as groof in 15.4%.There was neither significant canal nor groof in 4.8%.The vomerovaginal canal demonstrated as complete canal in 36.7% of the speciments,while appeared as groof in 33.3%.This canal was communicated with the lateral palatovaginal canal in 15% and it was not detected in 15%.Four typical slices of the celloidin and 3 plane of CT and 3 plane of MRI were selected and the key structures were described.Conclusion The palatovaginal canal and vomerovaginal canal can be well depicted on coronal plane.

Objective To investigate the value of bone turnover markers(BTMs) in forecasting the variance of bone mineral density (BMD) by studying the relationships between BTMs and BMD in persons aged 80 and above.Methods A sample of 1 509 subjects aged 80 and above was recruited.All subjects underwent BMD measurement by dual energy X-ray absorptiometry,and BTMs (C-telopeptide of type 1 collagen,N-terminal propeptide of type 1 procolagen,osteocalcin) measurements.The relationships among all the BTMs,and between BMD and BTMs were analysed.Results In subjects aged 80 and above,the relationships among BTMs were moderately positive(all P＜0.05).In men aged 80 and above,BMDs were inversely associated with BTMs(all P＜0.05),and in women,BMDs were inversely associated with osteocalcin (P＜ 0.05).Conclusions The clinical significance of BTMs in persons aged 80 and above indicates bone resorption when BTMs are raised.In men aged 80 and above any of BTMs may be selected to evaluate bone metabolism ; while in women,osteocalcin should be selected.

OBJECTIVE:To evaluate the adverse drug reaction(ADR) induced by Antongding and its safety in use.METHODS:According to the organ/system type recommended by WHO,34 cases with ADRs induced by Antongding were classified.The ADRs in this series were analysed concerning clinical manifestations,severity of symptoms and inducing mechanism and the safety of use of Antongding was discussed.RESULTS:8 organs/systems were involved in 34 cases with ADRs,of them,18 cases had moderate and severe ADRs(52.94%).In vitro experiments showed that Antongding could inhibit CFU-GM in man.CONCLUSION:Antongding is apt to induce ADRs,so it has potential risk in use.

Objective To study the influences of ginsenoside Re on learning and memory abilities of natural apolexis rats and to probe its preliminary mechanism.Method Water maze test for old rats was used to observe the effect of ginsenoside Re on learning and memory,and electrophysiological technique to record the long-term potentiation(LTP)in basic synaptic transmission of the dentate gyrus in anesthetized rats.Results Ginsenoside Re can markedly counteract memory acquisition impairment in natural apolexis rats,and enhance the synaptic transmission in the dentate gyrus and form the LTP consequence.Conclusion Ginsenoside Re can improve the learning and memory obstacle in rats,the mechanism may correlate with its enhancing the basic synaptic transmission and promoting the magnitude of LTP of the dentate gyrus.

Objective To research patients with ophthalmologic perioperative information systems, strengthening the information management of nursing work, achieving consensus and sharing of health care information resources, and then to explore the clinical application effects of this ophthalmologic peri- opera-tive information systems. Methods The convenient sampling method was used in the study. The control group was consisted of 1 740 patients in our hospital from January to March 2013 (before the application of ophthalmologic perioperative information systems). The observation group included 2 078 patients of the same hospital (after the application of ophthalmologic perioperative information systems). The control group adopted routine pre- operative information acquisition method, the observation group applied ophthalmologic perioperative information systems, which included input function, reading function and statistical function. The incidence rate of canceled operation and satisfaction were compared between two groups. Results Ophthalmologic peri- operative information systems provided patients with information gathering, query and analysis in different periods. The rate of the canceled operation reduced in the observation group from 3.74% (65/1 740) to 2.69% (56/2 078) in the control group, χ2=3.91, P<0.05. The satisfaction degree increased from 91.84 % (1 598/1 740) in the observation group to 96.78% (2 011/2 078) in the control group, χ2=44.60, P<0.05, the difference was statistically different. The hospitalization days from April to September in 2013 shortened compared with those of the same period in 2012. Conclusions Ophthalmologic peri- operative information systems promotes the scientific and informatization of nursing information, which is worthy of wide clinic application.

Aim To explore the inhibitory effect of dexamethasone on the expression of SH2-B? in the lung and the visceral sensory afferent system(C7-T5 spinal ganglia and the corresponding posterior horn of the spinal cord)of asthmatic mice.Methods Murine model of asthma of BABL/c mice was induced by ovalbumin in vivo.By means of immunohistochemistry and Western blot,the expression of SH2-B? in the lung,C7-T5 spinal ganglia and corresponding spinal cord was detected and the inhibitory effect of dexamethasone on it was observed.Inspiratory airway resistance was measured with AniRes 2003 lung function system.Results The expression of SH2-B? in the lung,C7-T5 spinal ganglia and the corresponding spinal cord of the asthmatic mice was much higher than that of the control group and the dexamethasone group(P

Objective:To investigate the incidence of sarcopenia in maintenance hemodialysis (MHD) patients and analyze its influencing factors.Methods:Totally 441 non-hospitalized MHD patients in stable condition were selected,by bioelectrical impedance analysis (BIA) to test appendicular skeletal muscle mass(ASM), by testing grip strength of MHD patients, to assess Muscle strength, by gait speed test to measure the 4-m usual walking speed, to assess physical performance of MHD patients.Risk factors of sarcopenia were identified by Logistic regression analysis.Results:The total incidence of sarcopenia in 441 MHD patients was 16.55% (73/441) and the incidence of sarcopenia in patients over 60 years old was 28.91% (61/211).The results showed older age ( OR=0.213, 95% CI 0.099-0.458, P<0.01), Karnofsky ( OR=9.661, 95% CI 3.850-24.244, P<0.01), subjective global assessment ( OR=0.491, 95% CI 0.250-0.965, P=0.039), serum phosphorus ( OR=0.422, 95% CI 0.204-0.875, P=0.020) and body mass index ( OR=0.754, 95% CI 0.609-0.935, P=0.010) were risk factors of sacopenia. Conclusions:The incidence of sarcopenia in elder, performed less physical activity, malnutrition predisposed MHD patients was high, so to those patients we should be paid more attention and gave active interventions to reduce sarcopenia.

Background and purpose: Docetaxel plus prednisone chemotherapy can improve the patients' survival for castrate-resistant prostate cancer. Angiogenesis inhibitors can also inhibit the growth of tumor. The curative effect of combined treatment is still not clear. This study aimed to evaluate the efficacy of docetaxel plus prednisone combined with thalidomide in treating castrate-resistant prostate cancer (CRPC) patients with bone metastasis. Methods:A total number of 78 CRPC patients were selected in Fuzhou General Hospital from Dec. 2008 to Jun. 2015. Seventy-eight patients were divided into two groups: 40 patients in chemotherapy group (docetaxel plus prednisone) and 38 patients in combined treatment group (docetaxel plus prednisone combined with thalidomide). A total number of 78 subjects were evaluated by the effective rate, the remission rate of bone pain, the prostate specific antigen (PSA) progression-free surviv-al, the overall survival and adverse effect. Results: The response rate (65.79%) and the remission rate of bone pain (86.84%) in combined treatment group were both higher than those in chemotherapy group (40.00% and 60.00%, P<0.05). The PSA progression-free survival (4.13 months), progression-free survival (4.25 months) and the overall survival (18.06 months) in combined treatment group were all longer than those in chemotherapy group (3.54, 3.75 and 16.26 months). The PSA pro-gression-free survival was significantly longer in combined treatment group (P<0.05). There was no significant difference in the overall survival between two groups (P>0.05). The rates of adverse effects including peripheral neuritis and lethargy in combined treatment group (26.32% and 55.26%) were higher than those in chemotherapy group (5.00% and 17.50%, P<0.05). Conclusion: Thalidomide combined with docetaxel plus prednisone in CRPC patients with bone metastasis can prolong the PSA progression-free survival and overall survival. The adverse effects are mild. It may become a new choice of treatment for CRPC.

Medical violence is a typical crisis. The survey showed that medical students generally lacked effec-tive strategies to deal with medical violence and also were looking forward to receiving related education and training subjectively. It has positive theoretical and practical significance to carry out the crisis management education of medical violence among medical students. From the four levels of crisis management, through strengthening human-istic education, psychological health education, carrying out crisis experience teaching, conducting crisis response practice in teaching and other tries, to carry out crisis management education of medical violence among medical students can improve medical students' crisis prevention awareness, early-warning ability, handling ability and recovery ability, so as to provide useful reference for preventing and resolving medical violence and building a har-monious doctor-patient relationship.
