Methods We established medical cooperation organization structure to clarify the division of responsibility along with a quick assessment form , a process chart and a green channel for emergencey treat-ment.The above method was applied to intervene 32 patients with psychiatric symptoms secondary to aortic dissection and observe the diagnosis time , the time from diagnosis to surgery , the remission time of psychiatric symptoms , the incidence of adverse events and the length of stay. Results 32 patients were diagnosed within 30min followed by emergency surgery within 30min after diagnosis, which was 1-2 hours shorter than the previous diagnosis and surgery preparation time .5-21 d after surgery , psychiatric symptoms have been effectively controlled.Extubation, falling out of bed, self-injury or injury and other adverse events did not occur .No patient died, and the average length of stay was 13.5d, which was 1.75d shorter than the length of stay of previous similar patients . Conclusion The healthcare cooperation method can quickly identify patients with psychiatric symptoms secondary to aortic dissection , prevent adverse events and shorten the length of stay .

Objective To investigate the incidence and risk factors of deep vein thrombosis (DVT) in a cohort of Chinese patients with traumatic spinal cord injury (TSCI),and in addition,to evaluate the effect of injury types and concomitant injuries of other parts of body.Method Records of 143 casualties admitted to our institute for TSCI were analyzed retrospectively.Both lower extremities of all casualties were examined routinely with color Doppler ultrasonography (CDUS) before major surgical treatment.None of these casualties received any thromboprophylaxis before CDUS.Logistic regression was used to analyze risk factors of DVT.Results Of the 143 patients,32.2％ (n =46) suffered from DVT (proximal n =15,distal n =31).All casualties were diagnosed within one week after injury (mean 3.35 ± 1.65 days).Risk factors associated with DVT induced complete motor paralysis (odds ratio [OR] 5.05,95％ CI 1.70-14.90),concomitant fracture of lower extremities (OR 4.30,95％ CI 1.34-17.64),and lumbar vertebra injury (OR 4.29.95％ CI 1.50-10.83).Conclusions Clinically detectable DVT in TSCI are not uncommon in the Chinese population.Casualties with multiple risk factors may be benefited from early administration of thromboprophylaxis.

Objective:To investigate the effects of acupuncture therapy on acute cerebral infarction. Methods: Eighty patients with acute cerebral infarction were randomly divided into a treatment group of 40 cases and a control group of 40 cases. Xuanzhong(GB 39)-through-Sanyinjiao(SP 6) acupuncture was performed as a main treatment. The curative effects were compared between the two groups and the sizes of cerebral infarct, between pretreatment and posttreatment after one course of treatment. Results: The total recovery rate was 88.5% in the treatment group and 57.5% in the control group after one course of treatment. There was a significant difference between the two(P<0.05). The rate of change in the infarct for the better was significantly higher in the treatment group than in the control group. There was also a significant difference(P<0.05). Conclusion: This treatment is an effective method for lowering the rate of apoplectic disability and raising the cure rate.

Objective:To explore the value of stress hyperglycemia ratio (SHR) in predicting the prognosis of patients with acute heart failure (AHF).Methods:AHF patients admitted to the Emergency Department of Shanghai Jiao Tong University Affiliated Sixth People's Hospital from December 2016 to January 2019 were retrospectively included. Clinical data were recorded and SHR was calculated. According to the survival of the patients within 1 year, they were divided into the death group ( n=89) and the survival group ( n=218). Logistic regression analysis was used to analyze the risk factors of mortality. Kaplan-Meier analysis was used to evaluate the correlation between SHR and the prognosis of AHF patients. Results:A total of 307 patients aged 83 ( range 74-87) years old who met the inclusion criteria were included in this study, including 153 males and 104 females. The age, SHR and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) in the death group were higher than those in the survival group [84 (78, 88) vs 82 (72, 86), 1.11 (0.91, 1.51) vs 1.02 (0.86, 1.27), 5 351 (2 098, 14 039)μg/L vs 4 243 (2 294, 7 565)μg/L ]. The left ventricular ejection fraction (LVEF) in the death group was significantly lower than that of the survival group [53 (45, 57) % vs 58 (44, 64) %, P< 0.05]. Logistic regression analysis showed that SHR was an independent risk factor for death in AHF patients ( OR=2.397, 95% CI: 1.285-4.471, P< 0.05). Median SHR was used to draw the survival curve. Patients with high SHR had a lower cumulative survival rate, and the difference was statistically significant ( P<0.05). Conclusion:SHR can identify critically ill patients and is an independent risk factor for death in AHF patients.

OBJECTIVETo explore the action mechanism of electroacupuncture (EA) at "Shenmen" (HT 7) and "Sanyinjiao" (SP 6) on insomnia.

METHODSThirty SD rats were randomly divided into a blank group, a model group and an EA group, 10 cases in each group. The insomnia model was made by immobilization method in the model group and EA group. After model establishment, rats in the blank group and model group were treated with fixation and no treatment was given. Rats in the EA group were treated with EA at "Shenmen" (HT 7) and "San-yinjiao" (SP 6) for 15 min, once a day for 4 days. After treatment, the level of daytime and nighttime activity, open-arm entry percentage and open-arm time percentage of elevated plus-maze test were measured; the content of noradrenaline (NE), dopamine (DA) and epinephrine (EPI) in plasma and NE, DA in thalamus and brainstem were detected by using euzymelinked immunosorbent assay method.

RESULTSCompared with the blank group, the daytime activity was increased and nighttime activity was reduced in the model group (both P<0. 05); the open-arm entry percentage and open-arm time percentage of elevated plus-maze test were both reduced in the model group (both P<0. 05); the contents of NE, DA, EPI in the plasma and NE, DA in thalamus and brainstem were increased in the model group (all P<0. 05). Compared with the model group, the daytime activity was reduced and nighttime activity was increased in the EA group (both P<0. 05); the open-arm entry percentage and open-arm time percentage of elevated plus-maze test were both increased in the EA group (both P<0. 05); the contents of NE, DA, EPI in the plasma and NE, DA in thalamus and brainstem were reduced in the EA group (all P< 0. 05).

CONCLUSIONElectroacupuncture at "Shenmen" (HT 7) and "Sanyinjiao" (SP 6) can restrain the over-activity of the sympathetic-adrenal medullary system to treat the insomnia.

0bjective To establish a standard curve method with more accuracy employed in fluorescence real-time PCR(RT-PCR)as a alternation of the general method.Methods β-actin and KLK11 plasmid DNA for quantitative standard curve were constructed in our study,and Plasmids of β-actin was employed as a internal control.After serial dilution these plasmid were used as DNA standard to obtained slope.Expression of these two genes in malignant prostate cancer cell line LNCAP were tested by real-time PCR,and we analyzed the RT-PCR results with two different methods and compared their accuracy.Results Thestandards curves made from these linear DNA standards showed good linearity (R2=0.991 and 0.992 for β-actin and KLK11 standards graphs),but also displayed a discrepancy in their PCR efficiency(β-actin 123% and KLK11 99%).There were different results after two different stand curve analytical method:the expression of KLK11 mRNA in LNCAP was downregulated in general standard curve method.In the new analytical method,howerer,KLK11 upregnlated for 4.46-fold.And there was a significant difference between aplification efficiency of targt gene and internal control gene(t=4.829,P<0.05).Conclusions Compared with general standard curve method,the new advanced standard curve method described here avoids an error which considers there is identical amplification efficiency between target gene and internal reference gene.It is considered to be a more correct analytical method in fluorescence real-time PCR.

Objective Retrospectively analyzed the predictive value of imaging evaluation in stage Ⅱ/Ⅲ esophageal carcinoma patients treated with preoperative chemoradiotherapy.Methods A total of 145 stage Ⅱ/Ⅲ esophageal carcinoma pantients were enrolled.We analyzed the overall survival rates of the patients with pathological complete response (pCR) and those without (NpCR),X-film complete response (xCR) and those without (NxCR),RECIST complete response (rCR) and those without (NrCR).And we used Cox model for multivariate analysis.Results The rates of pCR,xCR and rCR were 33.8％,42.8％ and 38.6％ for all patients,respectively.The 1-,3-5-year overall survival rates were 87.8％,79.6％,61.2％ for pCR patients and 75％,40.6％,24.0％ for NpCR patients (x2 =20.215,P ＜0.05),respectively;The 1-,3-5-year overall survival rates were 80.6％,66.1％,51.6％ for xCR patients and 75％,44.6％,25.3％ for NxCR patients(x2 =8.895,P ＜0.05),respectively;The 1-,3-5-year overall survival rates were 83.9％,69.6％,53.6％ for rCR patients and 76.4％,46.1％,25.8％ for NxCR patients(x2 =10.862,P ＜ 0.05),respectively.Multivariate survival analysis using Cox regression model showed that pCR was a positive independent prognostic factor (HR =0.333,95％ CI:0.200-0.554,P ＜ 0.05).Conclusions Short-term imaging evaluation could effectively predict the prognosis of stage Ⅱ/Ⅲ esophageal carcinoma patients treated with preoperative chemoradiotherapy.And pCR was a positive independent prognostic factor.

The HPLC fingerprint differences ofRadix Platycodonis from different origins were studied to provide references for their quality control and production. The total platycodins were purified by DB101 macroporous resin. HPLC-ELSD fingerprints of the total platycodins for 39 batches ofRadix Platycodonis samples from 9 provinces were performed on an Agilent HC-C8 column (4.6 mm x 250 mm, 5μm) with gradient elution. The mobile phase was acetonitrile-0.5% acetic acid. The injection volume was 6μL. The flow rate was 0.5 mL·min-1. The temperature of drift tube was set at 90℃. And the gas flow (N2) was set at 1.2 mL·min-1. The results showed that there were large differences in the quality ofRadix Platycodonis from different origins with the common fingerprints of 6 batches of samples fromChifeng in Inner Mongolia as references. The quality ofRadix Platycodonis was closely related to the seeds, the ecological environment, the way of drying and storing and so on. It was concluded that it was important to strengthen the provenance base construction, standardization of the seeds, reasonable formulation of the regionalization, and standardization of the production processing for the cultivation and production ofRadix Platycodonis.
