Objective: To confirm the cognitive rationale of Guilty Knowledge Test (GKT) with a polygraph lie-detection test,explore the merits of GKT's variation as narrowing unclear range of guilty knowledge, and to discuss the problems of the commonly used scoring method which was introduced by Lykken initially in order to obtain more scientific scoring method in accordance with the cognitive rationale. Methods:40 college students were chosen as participants.The study was designed under non-motivational instructions and neutral materials of meaningless letter strings. Results: The lie detection accuracy of this research was 73% under standard GKT paradigm (namely, the tester knowing the guilty knowledge clearly) with the scoring method introduced by Lykken, which confirmed the cognitive rationale of GKT. The accuracy of reducing guilty knowledge range from 5 to 2 was 78.4% in the condition of unclear-clue GKT (namely, the tester only knowing the guilty knowledge in the range of five items) with the scoring method of height and vicinity.Conclusion: The accuracy of lie detection with standard GKT in this study is similar to top accuracies of foreign studies with the same pattern and verified the rationale of cognition for GKT. The innovative scoring method suggested in this paper bears merits in application and is worth further studying.

The analgesic, sedative and convulsive effects of procaine were determined by animal experiments. The analgesic ED50 of procain were 21.7mg/kg or 52.8ug/ each (iv or icv, hot plate) and 29.2mg/kg or 52.2ug/ each (iv or icv,electral stimulation) in mice.Procaine In subthreshold dose had additive hypnotic effect of phenobarbital in mice and rabbits, but could not de crease spontaneous activity in mice.The convulsive ED50 of procaine were 13.5mg/kg (iv) or 2.4mg/each (icv) in rabbits.There was no influence on the righting reflex in all the experiment animals when iv or icv procaine was given alone.These results suggest that the analgesic and sedative effects of procaine are weak, but may be potentiated when administered concomitantly With other potent drugs.

The interaction between sodium oxybate and ketamine were studied in conscious animals. Sodium oxybate increased the LD_(50) of ketamine, increased the incidence of sleep caused by ke tamine and prolonged the sleep duration and potentiated analgesic action of ketamine. Sodium Oxybate didn't effect the respiratory and circulatory function in rabbits. The results showed sodium oxybate po tentiated the anesthetic action of ketamine and reduced the side effect of ketamine. So It is suggested that sodium oxybate has the anesthetic synergism with ketamine in animals.

Objective To observe the behavioral and the histopathology changes and expression of NR2B subunit in spinal dorsal horn in chronic constriction injury (CCI) rats after pulsed radiofrequency (PRF). Methods Forty-eight adult Sprague-Dawley rats were randomly divided into Sham-Sham (SS), Sham-PRF (SP), CCI-Sham (CS) and CCI-PRF (CP) groups. The right sciatic nerves (SNs) of the CS and CP groups were ligated to create the CCI model. For the SS and SP groups, the right SNs were separated without ligation. The CP and SP groups accepted PRF at the ligation site 15 days after modeling, while the electrode was placed in rats in the SS and CS groups without elec-tricity. The hindpaw withdrawal threshold (HWT) was measured before and 3, 7, 11, 15 days after modeling, and 1, 3, 7, 11, 15 days after treatment. The right SNs at ligation sites were assessed with optical microscopic score 15 days after treatment, and the NR2B expression in the L4-6 spinal dorsal horn were determined with Western blotting. Results HWT was significantly shorter in the CS and CP groups than in the SS and SP groups after modeling, and was more in the CP group than in the CS group. Under the optical microscope, the axonal diame-ter and myelin sheath thickness increased in the CP group compared to those in the CS group (P<0.01), the NR2B expression was less in the CP group than in the CS group after treatment (F=10.769, P<0.05). Conclusion PRF may reduce hyperalgesia and repair damaged SNs in CCI-induced neuropathic pain, which may associate with inhibition of the NR2B subunit expression in spinal dorsal horn.

Objective To explore the tubal patency after laparoscopic salpingotomy and embryo removal for tubal ectopic pregnancy. Methods A retrospective analysis was made on 28 patients receiving laparoscopic salpingotomy at other hospitals from September 2013 to September 2014.Within their 6 postoperative months, these patients were given hysterosalpingography in this gynecological minimally invasive center to evaluate the tubal patency. Results There were 6 cases of ipsilateral tubal patency (21.4%) and 22 cases of tubal obstruction or dropsy (78.6%), while 19 cases of contralateral tubal patency (67.9%) and 9 cases of tubal obstruction or dropsy (32.1%).Bilateral tubal embryo removal was carried out in 3 cases, with hysterosalpingography showing bilateral tubal obstruction in 2 cases and bilateral tubal dropsy in 1 case.One patient had ipsilateral tubal obstruction after tubal embryo patency and developed contralateral tubal patency after conservative treatment.Follow-up of the 28 cases for 6-15 months showed 4 cases of intrauterine pregnancy, 4 cases of examination of ovulation, 7 cases of preparation of assisted reproduction, 3 cases of laparoscopic salpingoplasty 1-2 months after hysterosalpingography, 1 case of endocrine regulation monitoring ovulation, 1 case of abnormal uterine bleeding 13 months later ( hysteroscopic examination showed endometritis and diagnostic curettage found proliferative phase endometrium that consistent with the menstrual cycle), and 8 cases without further treatment. Conclusion Laparoscopic salpingotomy for tubal ectopic pregnancy does not improve patient’ s tubal patency.

OBJECTIVE:To explore the clinical efficacy and safety of oxymatrine membrane,rhEGF gel respectively com-bined with Yunnan baiyao for postoperative cervical wound after LEEP. METHODS:300 patients with cervical intraepithelial neo-plasia(CIN)Ⅱ and Ⅲ were divided into group A,B,C(100 cases in each group)based on CIN grading and stratification and random sampling in each stratification. After conventional LEEP,patients in group A were cleaned the wound by 0.9% Sodium chloride injection,spraying Yunnan baiyao powder,once only after surgery;patients in group B were additionally given recombi-nant human epidermal growth factor (rhEGF) on the basis of group A,once every week after surgery,for 3 weeks;patients in group C were additionally given oxymatrine membrane on the basis of group A,1 tablet every evening after surgery,for 2 weeks. Postoperative bleeding,bleeding duration,rebleeding and duration after postoperative bleeding stopped,postoperative drainage du-ration,the incidence of adverse reactions in 3 groups were observed. RESULTS:The patients of postoperative bleeding,bleeding time ≥7 d and rebleeding after stopping bleeding in group B were significantly lower than group A;the incidence of bleeding time ≥7 d in group C was significantly lower than group A,the proporition of postoperative drainage duration for less than 7 d was significantly higher than group A,for 8-13 d was significantly less than group A;early wound healing rate in group B and group C were significantly better than group A,with statistical significances (P<0.05). There were no significant differences in above-mentioned indexes in group B and group C(P>0.05),and there were no obvious adverse reactions in 3 groups. CONCLU-SIONS:Oxymatrine membrane and rhEGF gel respectively combined with Yunnan baiyao have better healing than Yunnan baiyao alone,do not increase the incidence of adverse reactions,while there is no significant difference in oxymatrine membrane and rhEGF gel.

Objective To establish the model of hyperlipidemie acute pancreatitis(AP)to explore the mechanism of hyperlipidemia in aggravating AP.Methods Sprague-Dawley rats were divided into four groups at radmon:1)control group(C);2)hyperlipidemic group(TG);3)acute pancreatitis group(AP);4)hyperlipidemic acute pancreatitis group(HAP).After 8 weeks,blood,pancreas and peripancreas tissue were collected from each rats for determination of various parameters.Results The levels of hyperilidemic index were elevated in HAP group compared with those of other groups.The ADP/ATP ratio was obviously increased in HAP group.Caspase-3 and caspase-8 of HAP group presented in zymogen forms,while in AP group they were in activity forms.After the pancreas issue were stained bv HE and further analyzed through TUNEL assay,we found that there were more pancreatic acinar cells undergoing necrosis in HAP group.Conclusion Hyperilidemia may promote the course of apoptosis to necrosis of pancreatic acinar cells,which may be the mechanism of deterioration in hyperlipidemic acute pancreatitis.

BACKGROUND: Nano-hydroxyapatite (Nano-HA) has been shown to be a good choice of bone repair material owing to its salts composition consistent with natural bone and its scaffold structure homothetic to natural bone structure. OBJECTIVE: To investigate the feasibility of nano-HA in repair of jaw bone defect in rabbits. DESIGN, TIME AND SETTING: Materials-based animal experimental observation was performed at Laboratory Animal Center of Jiamusi University and Beijing Ji Shui Tan Hospital between January 2003 and June 2005. MATERIALS: Neutralization reaction of calcium biphosphate and calcium hydroxide was used to construct the system. The reactants were managed to be cotloidal by reaction control and using appropriate nucleating agents. Acerata HA crystal obtained under different conditions was sintered to obtain the nano-HA granule with a diameter of 1-56 nm. METHODS: Twenty-four healthy Chinese Harbin rabbits were randomly and evenly divided into an experimental group and a control group. After anesthesia, a penetrating 1.5 cm x1.5 cm defect was made with the GX micro-drill at the mandibular edge in each rabbit. Nano-HA was implanted in defects of the experimental group, and common HA was used in the control group. Antibiotics were used for 5 days afterwards. MAIN OUTCOME MEASURES: Change in bone mineral density after implantation of nano-HA. RESULTS: After repair of bone defect, the bone mineral density in the expedmental group increased gradually to a normal level and tended to be stable; whereas it was gradually decreased in the control group. There was significant difference between the experimental and control groups (P < 0.01). CONCLUSION: Nano-HA can promote new bone maturation, and this material produces favorable results in repair of bone defects.

Objective To evaluate whether serum cystatin C (SCys C) could be used as an ideal index to assess renal function of renal transplant recipients during posttransplant follow-up.Methods Seventy patients who were followed up for at least 6 months after renal transplantation in our centre were recruited in the study. SCys C and serum creatinine (SCr) were determined during the follow-up period, and glomerular filtration rate (GFR) was measured using an isotope Tc99m DTPA.The correlation between SCys C, SCr and GFR was analyzed. The performance of SCys C and SCr in diagnosing the mild impairment of renal allgraft function (GFR ＜ 1 ml/s) was evaluated using ROC curve. Results Both SCys C and SCr had a linear negative correlation with GFR (r = -0. 82 and -0. 66 respectively, P＜0. 01 ). The sensitivity, specificity and positive predictive values (PPV) of SCys C for diagnosing the mild impairment of renal allgraft function were higher than those of SCr,but the AUC of SCys C did not differ from that of SCr significantly (0. 935 vs. 0. 877, P＞0. 05).Conclusion SCys C could be used an ideal index to evaluate the allograft renal function for its better correlation with actual GFR.
