The effects of morphine and its antagnoist naloxone on the VRR were studied. Morphine, at lower concentration (3.5 ? 10~(-7)～10~(-5)M), enhanced the VRR of toad spinal cord. This effect is proportional to its concentration within certain range, even though it depressed the ARR at higher concentration (5.3?10~(-5)-8.08?10~(-5)M). When naloxone was given alone. it did not excite or depress the VRR. While the VRR was enhanced by morphine, naloxone could antagonixe the exciting effect of the former. Experiments showed that naloxone could antagonize the exciting effect on the VRR produced by morphine.

Visual processing was an important approach to study brain's higher functions such as information process,study,memory,linguistic process,etc.As a major visual area,occipital region became a research focus,and the authors would talk about the working mechanism of occipital region in brain according to the progresses of neuroscience.

In this article, the main effective components of Radix Polygoni Multiflori and their pharmacological effects, toxicity and the possible mechanism, adverse reactions in clinical applications are reviewed.

Objective: To investigate the relationship between G505A polymorphism in the encoding region of thrombin-activated fibrinolysis inhibitor (TAFI) and cerebral infarction in Chinese Han population. Methods: A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used to detect G505A polymorphism in the encoding region of TAFI in 130 patients with cerebral infarction and 118 healthy individuals. Results: The GG genotype of TAFI G505A accounted for 35.4% (46/130) and GA or AA genotype accounted for 64.6% (84/130) in the cerebral infarction group; and they were 49.2% (58/118) and 50.8% (60/118) respectively in the control group. The difference was statistically significant (P = 0.028). The G and A allele frequencies were 60.4% (157/260) and 39.6% (103/260) respectively in the cerebral infarction group, and they were 69.9% (165/236) and 30.1% (71/236) respectively in the control group. The difference was statistically significant (P = 0.026). Multivariate logistic regression analysis showed that G505A polymorphism in the encoding region of TAFI was an independent risk factor for cerebral infarction (OR = 2.660, 95% CI 1.330-5.317, P = 0.006). Conclusion: The TAFI G505A polymorphism may be one of the risk factors for cerebral infarction.

OBJECTIVETo compare the efficacy differences between dog-days medicinal vesiculation and regular-day medicinal vesiculation for perennial allergic rhinitis (PAR), and observe their effects on serum immune globulin E (IgE) and interleukin-4 (IL-4).

METHODSSeventy-two patients were randomly divided into a dog-days moxibustion group (34 cases) and a regular-day moxibustion group (38 cases). In the dog-days moxibustion group, medicinal vesiculation was applied on the 1st dog-day, 2nd dog-day and last dog-day in summer by lunar calendar, 3 treatments per dog-day for totally 9 times. In the regular-day moxibustion group, the moxibustion was given on the regular day for continuous 9 times. The symptom score, rhinoconjunctivitis quality of life questionnaire (RQLQ) and the level of IgE and IL-4 were compared before and after treatment in two groups; the short-term and two-year efficacy evaluation were performed too.

RESULTSThe short-term total effective rate was 88.2% (30/34) in the dog-days moxibustion group, which was not significantly different to 86.8% (33/38) in the regular-day moxibustion group (P>0.05). The long-term total effective rate was 97.1% (33/34) in the dog-days moxibustion group, which was significantly superior to 81.6% (31/38) in the regular-day moxibustion group (P<0.05). After treatment, the serum IgE, IL-4 and RQLQ were significantly reduced (all P<0.01), but the difference between two groups was not significant (all P>0.05).

CONCLUSIONMedicinal moxibustion could be taken as a regular treatment for PAR, which could be performed during the whole year, and dog-days moxibustion could be considered as an enhanced method for prevention and treatment of PAR.

Objective To investigate the changes and possible mechanisms of the expressions of metabolic pattern glutamic acid receptor 1(mGluR1) and mGluR3 in hippocampus of juvenile rats submitted to lithium chloride-pilocarpine induced model of epilepsy in 6 h,5 d,60 d after status epilepticus(SE) onset.Methods Seizures were induced in the juvenile rats with lithium and pilocarpine injected intraperito-neally,and behavioral changes and EEG were observed.Eighteen SD juvenile rats with SE were randomly divided into following groups: groupⅠ,in which the rats were killed at 6 h after SE onset(6 h SE),group Ⅱ,in which the animals were killed during the seizure-free period(5 days after SE onset),and group Ⅲ,in which the animals were killed in 60 days after SE induction(period of spontaneous recurrent seizures).And intraperitoneal injection of saline water control groups were divided into: groupⅠa,group Ⅱa and group Ⅲa.The hippocampus tissues after the rats were put to death were collected,the expressions of mGluR1 and mGluR3 mRNA were detected by reverse transcriptase polymerase chain reaction(RT-PCR) in the hippocampus of juvenile rats.Results EEG of rats in group Ⅰ were abnormal,but normal in groupⅡ,and 5(83%) cases of the juvenile rats in group Ⅲ manifested dissemination of sharp waves,spikes or spike wave.The saline control group did not spontaneously attack.There was more significant upregulation of mGluR1 mRNA expression(Pa0.05).The expressional levels of mGluR3 mRNA were upregulated in groupⅠ,group Ⅱ and group Ⅲ(Pa

ObjectiveTo investigate the effects of dexmedetomidine on postoperative cognitive dysfunction (POCD) in the elderly patients undergoing laparoscopic radical trachelectomy.MethodsSixty ASA Ⅰ or Ⅱ patients (aged 65-80 yr and weighing 55-74 kg) undergoing elective laparoscopic radical trachelectomy were randomly divided into two groups:30 patients received intravenous injection of dexmedetomidine 0.2 μg · kg - 1 ·h- 1 ( group D EX) and 30 received same volume of normal saline (control group,group NS) after induction of anesthesia.Cognitive function was assessed at 1 day before operation and on the 7th day after operation using a battery of nine cognitive dysfunction tests.ResultsCompared with group NS,on the 7th postoperative day,the incidence of POCD was decreased in group DEX ( P ＜ 0.05 ).ConclusionDexmedetomidine can improve POCD in the elderly patients undergoing laparoscopic radicaltrachelectomy.
