Objective: To explore the effect of traumatic asphyxia on mental health of adolescents. Method: Forty-four adolescents were assessed with Styles Questionnaire (SCL-90), Eysenck Personality Questionnaire (EPQ) after one week, 6 weeks, 10 weeks, 16 weeks and 34 weeks of asphyxia. Post-traumatic Stress Disorder (PTSD) was diagnosed according to CCMD-2-R. Results: All 44 adolescents suffered from traumatic asphyxia had some psychiatric symptoms. Nineteen of them fulfilled the symptomatic criterta of DTSD in the first week,10 of them were diagnosed as PTSD at the 6th week,8 of the them returned to normal after 34 weeks. Conclusion: Mental health of adolescents suffered from traumatic asphyxia need our attention.

Pituitary metastasis is a rare tumor complication, and papillary thyroid carcinoma is a tumor with low hematogenous dissemination tendency. Here we report a rare case with pituitary metastasis from papillary thyroid cancer. This patient was 43 years old and was admitted to our hospital because of " blurred vision in the right eye" . She had partial thyroidectomy because of thyroid nodule 8 years ago, and was diagnosed as papillary thyroid carcinoma, but without any further treatment onwards. After admission, MRI revealed a pituitary mass protruding through the sella turcica into the right sphenoid sinus. Neuro-endoscopic transsphenoidal resection was performed to relieve visual impairment. Pathological result was papillary thyroid carcinoma pituitary metastasis. She underwent thyroidectomy 2 months later. Because tumor of the left lobe invaded the esophagus, it was resected palliatively, and adjuvant therapy with radioactive iodine was performed subsequently. This case suggests that long-term management of papillary thyroid carcinoma should be strengthened to reduce the risk of recurrence and metastasis, additionally radioiodine therapy is an important complementary treatment.

Objective To investigate the value of blood oxygenation level dependent (BOLD) MRI in detecting monkey cerebral ischemic penumbra (IP). Methods Six monkeys were used to make reversible middle cerebral artery occlusion (MCAO) model by an interventional microcatheter method. MR DWI, PWI mean transit time (MTT), T_2WI and quantitative T_2 map, T_2~* map were performed at MCAO (0 h) and 1,3,6,12,24,48 h after reperfusion. Reversible transverse relaxation rate (R_2') BOLD imaging was calculated using quantitative T_2 and T_2~* maps. Lesion volume percentage (lesion volume/bilateral hemispheres volume) were measured on 0 h DWI,48 h T_2WI and TTC staining. Ischemic area was subdivided into infracted core (high signal area on both 0 h DWI and 48 h T_2 WI), IP (high signal on 0 h DWI, iso on 48 h T_2 WI) and oligemia (0 h delayed MTT, iso signal on both 0 h DWI and 48 h T_2 WI). Relative R_2' (rR_2') was calculated to get ratio between the lesion and mirror area in contralateral healthyhemisphere. Paired t test and correlation analysis were used for comparison of lesion volume percentage. rR_2' values at each time point were compared by ANOVA. Results Reversible MCAO models were made successfully in 4 of 6 monkeys. Lesion volume porcentage on 48 h T_2 WI was reduced compared to that on Oh DWI [ (8.16±0.55)% vs (11.37±1.41)% ,t=6.472,P<0.05]. There was no significant difference in lesion volume percentage between TTC staining and 48 h T_2 WI[ (8.15±0.62)% vs (8.16±0.55)%, t= 0.150,P>0.05], which showed significant positive correlation (r=0.98, P<0.05). rR_2' values were significant different at each time point, with highest in ohgemia followed by IP and infarcted core (P< 0.05). rR_2' values in infracted core, IP and oligemia were: 0 h(1.129±0.108,1.329±0.081,1.584± 0.103,F=36.19,P<0.05),1 h(0.668±0.082,1.237±0.072,1.435±0.066,F=134.09,P<0.05), 3 h (0.536±0.075,1.453±0.081,1.770±0.141, F=256.30, P<0.05), 6 h (0.259±0.050,2.435± 0.131,2.957±0.177,F=803.25,P<0.05), 12 h(0.385±0.054,2.447±0.148,3.254±0.184,F= 743.74,P<0.05),24 h(0.083±0.026,1.968±0.127,3.101±0.144,F=1236.26,P<0.05),48 h (0.246±0.058,3.694±0.218,4.297±0.322, F=557.02, P<0.05). After reperfusion, rR_2' values in IP and oligemia showed increased trend with time evolution and reflected positive BOLD effect, while the infracted core showed decreased trend, reflecting negative BOLD effect. Conclusion R_2' BOLD can delineate IP from infracted core according to the difference of oxygen metabolic status in ischemic brain tissue.

Objective To study the influence of defection of Fragile X mental retardation-1 gene (FMR1) on cyclic adenosine monophosphate (cAMP) and to discuss its mechanism. Methods FMR1 gene of peripheral blood mononuclear cell was silenced in vitro by sodium nitrointroprusside. The effect of gene-silencing was detected using reverse transcript polymerase chain reaction (RT-PCR). The specific activity of adenylate cyclase and phosphodiesterase was showed by the activity ratio of yield or consumption of cAMP during a unit time. Spectrophotometry was used to measure the two key enzymes (adenylate cyclase and phosphodiesterase), as to determining the level of intracellular cyclic adenosine monophosphate in the process of cAMP metabolism. Results FMR1 gene was fully silenced by sodium nitrointroprusside at 12th, 24th and 48th hour separately, re-expressed at 72th hour. If the cultivated fluild was replaced with new sodium nitrointroprusside at 48th hour, FMR1 gene would be silenced continuously. The intracellular cAMP level in the gene silenced group was lower, and significant depression of adenylate cyclase specific activity was found in the FMR1 gene silenced group (P=0.000). No significant difference was found on phosphodiesterase specific activity (P=0.983). Conclusions The results suggest that the yield of cAMP could be influenced by defection of FMR1. The depression of adenylate cyclase activity might be one of the causes of the decrease of intracellular cAMP production.

Objective To observe the influences of different analgesic methods on blood sugar, stress hormones and cytokinesMethods According to different postoperative analgesic methods, 30 patients immediately after elective cholecystectomy, were randomly divided into four groups: normal saline was infused epidurally in group C as control; analgesia via epidural infusion of morphine 2 mg in group EM; patient-controlled analgesia via epidural or intravenous fentanyl in group PCEFA or group PCIFABlood sugar, cortisol, insulin, interlukin-2 (IL-2), interlukin-6 (IL-6) and tumor necrosis factor-?(TNF-?) levels were determined during the perioperative periodResults Postoperative visual analog score was higher in group C than that in group EM, group PCEFA or group PCIFA (P005)Conclusions Postoperative application of PCEFA can much more help to maintain the stability of neuroimmunoendocrinal system

Objective To explore the regularity of changes of plasma endothelin (ET), throm-boxame B2(TXB2) and 6-keto-prostaglandin F1α(6-keto-PGF1α) and restenosis after percutaneous transluminal angioplasty (PTCA) in patients with coronary heart disease. Methods Radioimmunoas-say was applied to measuring plasma levels of ET, TXB2and 6-keto-PGF1αat 0,30 min, 1 day and 3 days after PTCA in 41 patients with coronary heart disease. Results The level of ET in the patients with coronary heart disease was significantly decreased in 30 minutes after PTCA (P＜0.05), but no significant difference was observed in 1 day and 3 days after PTCA (P>0.05). The level of plasma TXB2has no statistical difference after PTCA in 30minutes, 1 day and 3 days (P>0.05). The level of 6-keto-prostaglandin F1α(6-keto-PGF1α) of the patients with coronary heart disease was significantly declined in 30 minutes after PTCA (P<0.05) ,but no significant difference was observed in 1 day and 3 days after PTCA (P>0.05). Conclusion PTCA may lead to fluctuation of plasma levels of ET, TXB2and 6-keto-PGF1αThe clarification of changing regularity of these vasoactive substances contrib-utes to prevention of acute artery occlusion or restenosis after PTCA.

Objective To observe the effects of blood nourishing and wind expel formulae on learning and memory capabilities of rats with tic disorders. Methods Intradialytic Parenteral Nutrition peritoneal injection was used to establish the rat model of tic disorders. The successful test subjects were categorized into 5 different groups, namely the model group, the Chinese medicine groups (low dosage, medium dosage and high dosage) and the western medicine group. The test groups were each given gastric perfusion of the related medicine, whereas the control and model groups were each given equal amounts of saline solution continuously for 8 weeks. Open field test and water maze test were carried out in the 1st, 4th and 8th weeks to evalute the learning and memory capabilities. Results In comparison with the control group, the model group showed obvious increase in movement across grid and decrease in vertical locomotion. Statistical significance was obtained showing an increase in vertical locomotion in the treatment groups compared with the model group. In the Chinese medicine groups, the medium and high dosage groups exhibited shorter escape latency and increased exploratory behavior (P<0.05) in the 4th and 8th weeks. Conclusion Among the blood nourishing and wind expel formula, the medium and high dosage showed ameliorating effects on the memory and learning capabilities of rats with tic disorders.

The application of continuous quality improvement program in standardized residency training examination in the central Hospital of Shanghai Jiading was introduced to inquire into the way to improve the quality of standardized training of resident doctors.

The percentage of the students that passed the licensed medical skills examination was 96.6%in that year. 100%of the students passed the graduation comprehen-sive examination. Year-end evaluation showed that the students' satisfaction degree to the teachers increased from 94.5%to 98.2%. Thus, through the implementation of CQI project, we achieved the goal of promoting teaching and promoting learning.

OBJECTIVE:To study the influence of calcineurin gene polymorphism on the efficacy of cyclosporine A (CsA). METHODS:The blood samples of patients treated with CsA were collected. The trough blood concentration of CsA was detected by EMIT. The genotype of PPP3CA and PPP3CB was assayed by RFLP-PCR method. The expression of NFAT-regulated gene IL-2, IFN-γand GM-CSF were measured by RT-qPCR,which were used to define the index of indirect efficacy of CsA. The relationship of gene polymorphism with CsA efficacy was study by relationship analysis and multiple factor regression method,etc. RESULTS:A to-tal of 100 blood samples were collected. There was no significant correlation between the expression of CsA efficacy-related NFAT-reg-ulated gene GM-CSF and trough concentration of CsA(rGM-CSF=-0.04,P=0.238);the expression of IL-2 and IFN-γ were negatively correlated with trough concentration of CsA significantly(rIL-2=-0.384 3,P<0.001;rIFN-γ=-0.335 4,P<0.001). Using the average value of mRNA expression of IL-2 and IFN-γas indirect efficacy index,the polymorphism of PPP3CB rs3763679 site significantly in-fluenced the efficacy of CsA(P<0.05),but PPP3CA rs3804358 had no any effect on it(P>0.05). Stratified analysis showed that among patients with immune disease underwent renal transplantation,efficacy of patients with PPP3CB rs3763679 genovariation(TC+TT) were better than those with wild-type gene (CC)(P<0.05). After the efficacy was normalized by CsA trough concentration, multivariate analysis showed that normalized efficacy of CsA was negatively correlated with gender,PPP3CB rs3763679,lactate dehy-drogenase and creatinine significantly,but positively correlated with PPP3CA rs3804358,leucocyte count,usea nitrogen,glycerin trilaurate,etc. CONCLUSIONS:PPP3CB rs3763679 gene polymorphism influence the efficacy of CsA;among patients with immune disease underwent renal transplantation,efficacy of patients with PPP3CB rs3763679 TT+TC is better than that of CC type. At the same time,gender,PPP3CA rs3804358,leucocyte count,usea nitrogen,glycerin trilaurate and other factors all can influence the nor-malized efficacy of CsA to different extent. Multiple factors should be considered when using CsA.
