Objective To investigate the role of NMDA receptors in central medial thalamus (CMT) in the unconscious?ness induced by general anesthesia. Methods A total of 60 rat models for microinfusion were assigned into 4 groups (n=15 for each group). After induction with propofol, 10 mmol/L (NMDA10 group), 20 mmol/L (NMDA 20 group) and 40 mmol/L (NMDA40 group) of NMDA and normal saline (group C) with equal volume were microinfused into CMT. The incidence of purposeful movement and recovery time of righting reflex were observed in each group respectively. Infusion sites were local?ized by histological method. Results When the microinfusion site localized within CMT, comparing with group C, the recov?ery time of righting reflex reduced notably in three NMDA groups (P<0.05). The recovery time was significantly shorter in NMDA20 group and NMDA40 group than that of NMDA10 group. The incidence of purposeful movement during propofol an?esthesia was higher in NMDA20 group and NMDA40 group than that of group C (P<0.05). When the microinfusion site lo?calized out of CMT, the recovery time of righting reflex was remarkably longer than that within CMT in three NMDA groups (P<0.05), and there was no significant difference in the incidence of purposeful movement and recovery time between four group (P>0.05). Conclusion Microinfusion of NMDA agonist into CMT reverses propofol anesthesia, indicating that NMDA receptor in CMT may contribute to the propofol-induced unconsciousness.

Objective:To evaluate the vomer development of cleft palate patients.Methods:38 patients over 1 4 years(averaged 23.4 years)of age with cleft palate and 76 controls of normal people(aged 22.8 year on average)were included.The 3D computed tomo-graphy reconstruction images of the bony nasal septum were measured.The development of the vomer was evaluated by comparing the L1 (the length of the lower edge of the vomer),L2 (the length from nasal spine to the point of the sella)and S (the approximate area of vomer)among deferent groups.Results:The L1 ,L2,and S of cleft palate patients were smaller than those of the controls(P <0. 05).Compared with the postoperative cleft cases,the S and L2 of preoperative cases were bigger(P <0.05).Conclusion:The vomer development is adversely affected by cleft palate.Not only the vomer-palate fusion is lower,but also the sutura between vomer and na-sal septum cartilage and ethmoid bone are short.And the latter is greatly influenced by surgical trauma.

Objective To analyze the epidemiological characteristics of overseas imported malaria reported in Chongqing City from 2011 to 2015,so as to provide the evidence for improving the imported malaria control strategies. Methods The epi-demiological data of overseas imported malaria cases were collected and analyzed descriptively for the species,original coun-tries,diagnosis and treatment in Chongqing City from 2011 to 2015. Results A total of 148 overseas imported malaria cases were reported in Chongqing City from 2011 to 2015,in which 96(65.54%)cases were falciparum malaria,and 37(24.32%) cases were vivax malaria;125(84.46%)cases were infected in Africa,and the rest of 23(15.54%)cases were infected in Southeast Asia. Most of the patients were 30 to 50 years old male workmen,and the ratio of male to female was 11.42:1. There was no obvious seasonal distribution among the reported timelines of the cases;however,there were two small peaks from June to August and from January to February. The median interval time of imported malaria cases from malaria onset to see a doctor was 1 day and from seeing the doctor to get malaria diagnosis was 2 days. The patients'first selected institutions were county medical institutions(50 cases,33.78%),then provincial medical institutions(36 cases,24.325%)and private doctors(20 cases,13.51%),and only 79(53.38%)patients got malaria diagnoses in their first selected institutions. The standard treatment were provided to 142(95.54%)cases. There were 43(29.05%)patients had serious complications and three patients were dead. Conclusion It is very important to enhance the multi-sector's collaboration to establish the collaborative investigation mechanism for screening malaria patients,and strengthen malaria health education for overseas workers and training courses in primary care medical institutions.
