BACKGROUND: The neurological basis for learning and memory is the high plasticity of central nervous system, and special rehabilitative training is necessary in the process of the functional recombination of central nervous system.OBJECTIVE: To observe the capability of rehabilitative training in differentiating learning ability and memory maintaining of one-trial passive avoidance response, and its correlation with the kinetic properties of Nmethyl-D-aspartic acid (NMDA) receptor channel of contralateral hippocampal neuron in rats with cerebral infarction.DESIGN: A randomized control animal trial.SETTING: Department of Rehabilitative Medicine, Affiliated Hospital of Luzhou Medical College.MATERIALS: The experiment was carried out in the central laboratory of Luzhou Medical College between March 2000 and February 2002. Twentyfour male Wistar rats were randomly divided into three groups with 8 rats in each: free movement after cerebral infarction group (model group), rehabilitative training after cerebral infarction group (rehabilitation group) and normal group.METHODS: ① Model establishment: Rats in the model group and rehabilitation group were made into models of infarction of right middle cerebral artery, and those in the normal group were not given any treatment. ②Rehabilitative training: After 4 days, only the rats in the rehabilitation group were trained with rolling-cage exerciser, screen exerciser and balance exerciser for 4 weeks. ③ Learning and memory tests: The learning and memory performances of all the rats were tested at 35 days postoperatively. The Y-maze test was applied to mainly observe the needed number f training for the rats to reach 9/10 correct response (for running to dark arm), and the multi-functional conditioned reflex box to observe the stayed duration on the diving board (step-through latency). ④ The single channel current property of NMDA receptor in hippocampal neurons was recorded with cell adhesion after learning and memory tests.MAIN OUTCOME MEASURES: ① training times needed for the rats to grasp the structure of the maze in each group; ② step-through latency in each group; ③ single channel current property of NMDA receptor in each group.RESULTS: All the 24 rats were involved in the analysis of results. ① The training times needed for the rats to grasp the structure of the maze in the rehabilitation group and normal group were significantly different from that in the model group [(68.02±11.67), (57.62±10.31), (107.07±16.32) times, P ＜0.05], and there was no significant difference between the rehabilitation group and normal group (P＞0.05). ② The medians of step-through latency before shock in the rehabilitation group and normal group were significantly different from that in the model group (286.7 s, 298.4 s, 126.7 s, P ＞0.05), and there was no significant difference between the rehabilitation group and normal group (P＞0.05). ③ The 35 pS short open NMDA receptor channel mainly existed in the hippocampal neurons of rats in the rehabilitation group, the open proportion was 0.099±0.007. The duration and proportion of 20 pS short and long open and the 35 pS short open NMDA receptor channels in the hippocampal neurons of rats were not significantly different from those in the normal group (P＞0.05). In the model group, 20 pS open channel was mainly observed, and the durations of 20 pS short and long open channels were obviously shorter than those in the rehabilitation group, the open proportion of 35 pS short open channel was 0.036t0.04, which was lower than that in the rehabilitation group,but no 35 pS long open channel was observed.CONCLUSION: Rehabilitative training accelerates the recovery of the learning and memory abilities of rats with cerebral infarction by changing the NMDA receptor channel properties of contralateral hippocampal neurons.

Objective To dynamically measure cardiac output in shock neonates and to explore its clinical values.Methods The cardiac output and stroke volume of left ventricle in 30 shock neonates and 30 normal neonates were measured by noninvasive ultrasonic cardiac output monitor (USCOM) and the measurement was repeated in shock neonates after volume expansion and dopamine(2-4μg/(kg·min))treatment.Results The cardiac output and stroke volume of left ventricle in shock neonates ((0.36 ± 0.24) L/min,(3.5 ± 1.5) cm~3) were significantly lower than those in normal neonates ((0.49 ± 0.15) L/min,(2.7 ± 1.6) cm~3)) and however were improved significantly after volume expansion and dopamine treatment ((0.52 ± 0.28) L/min,(3.8 ± 1.8) cm~3).The urine volume was also increased significantly after treatment (P < 0.05).Conclusions Dynamic measurement of the cardiac output in early shock neonates might offer guidance on clinical fluid resuscitation.

Purpose To discuss the relationship between age of onset and the HPV types infection in cervical adenocarcinoma. Meth-ods This study included 120 specimens of cervical adenocarcinoma in Jiangxi Maternal and Child Health Hospital. The specimen blocks were sliced by sandwich method. DNA was amplified by SPF10-PCR method. DNA genotyping was used with LiPA method. All biopsy specimens had pathologic diagnosis. The HPV infection of cervical adenocarcinoma specimens was analyzed. Results 120 ade-nocarcinoma cases were included in this study. HPV positive rate was 77. 5% (93/120). HPV 18 was the most prevalent type, which took up 43. 01% (40/93) of the total HPV positive cases, as same as HPV 16, which took up 43. 01%(40/93) of the total HPV pos-itive cases. The average ages of HPV 16 and HPV 18 were 43. 41 and 41. 06 years old respectively, other HPV types were 46. 85 years old, which showed statistically difference (F=3. 58, P=0. 032). Conclusion HPV 18 and HPV 16 are two most prevalent HPV types in cervical adenocarcinoma. The cases of HPV 18 infection are younger than other HPV-types infection.

Severe burn is often accompanied by multiple organ damage. Acute lung injury (ALI) is one of the most common complications, and often occurs in the early stage of severe burns. If it is not treated in time, it will progress to acute respiratory distress syndrome (ARDS), which will be a serious threat to the lives of patients. At present, the treatment of ALI in patients with severe burn is still remained in some common ways, such as the liquid resuscitation, the primary wound treatment, ventilation support, and anti-infection. In recently, human umbilical cord mesenchymal stem cells (hUCMSCs) have been found having some good effects on ALI caused by various causes, but few reports on the efficacy of ALI caused by severe burns were reported. By reviewing the mechanism of stem cell therapy for ALI, therapeutic potential of hUCMSCs in the treatment of severe burns with ALI and a new approach for clinical treatment was provided.

BACKGROUND: Lung cancer keeps the first place in malignant tumor death all along. It is quite necessary to clarify the situation and tendency change of residents' lung cancer death for formulating prevention and cure strategy.OBJECTIVE: To investigate the lung cancer death characteristics, death trend and result out potential life loss of the residents in urban areas of Xuzhou.DESIGN: A retrospective descriptive epidemiology study.SETTING: Center for Disease Prevention and Control of Xuzhou.PARTICIPANTS: Totally 3 890 cases died of lung cancer between 1990 and 2003 in the urban areas of Xuzhou city. METHODS: Residents' lung cancer death characteristics and potential life span loss situation with parameters of crude death rate, standardized death rate, age specific death rate and potential life span loss and other indexes of the residents in the urban areas of Xuzhou city in 1990 and 2003were described.MAIN OUTCOME MEASURES: ①Crude death rate of lung cancer;②Potential life span loss; ③Life lost rate.RESULTS: ①During 14 years period , 3 890 cases of lung cancer death happened ,which accounted for 27.43% of total cases of malignant tumor death; ② year average death rate was 28.31/100 thousand, standardized death rate was 24.88/100 thousand, residents' potential life span loss caused by lung cancer death accounted for 24 230 people per year③ life decreasing rate was 1.19/1 000, standardized life decreasing rate was 1.45/1 000, each case of lung cancer death resulted in potential life loss of 6.23 years; males' death rate was higher than females'(x2=575.70,P ＜ 0.01), the ratio of male to female was 2.31:1. Age specific death rate of male and female after 20 years of age increased in an exponential manner.CONCLUSION: Lung cancer is the most serious malignant tumor that threatens the life health of residents in urban areas of Xuzhou city; the potential life span loss caused by lung cancer is very big. The amount of carcinogenic substances exposed in environments is closely related to the occurrence of lung cancer; therefore, prevention and control of lung cancer should be performed actively.

A safe and effective vaccine against the human immunodeficiency virus type 1 (HIV-1) is expected to have a considerable impact on elimination of acquired immune deficiency syndrome. Despite decades of effort, an effective vaccine against HIV-1 remains elusive. In recent years, the Thai HIV Vaccine Efficacy Trial (known as RV144) showed a reduction in HIV-1 acquisition by 31%, but this agent could not delay disease progression in vaccinated individuals. Clinical analyses of experimental data and experiments in vitro have revealed two main types of immunogen design: induction of broad-spectrum neutralizing antibody (bNAb) and cytotoxic T lymphocyte (CTL) responses. bNAb can prevent or reduce acquisition of infection, and its main immunogens are virus-like particles, natural envelope trimers and stable bNAb epitopes. An effective CTL response can slow-down viral infection, and its main immunogens are "mosaic" vaccines, "conserved immunogens", and the "fitness landscape" of HIV-1 proteins. This review summarizes the strategies as well as progress in the design and testing of HIV-1 immunogens to elicit bNAb and CTL responses.
