Based on the kinetics of alcohol metabolism in animal models,the mathematicalmode for studing of the alcohol kinetics in person of the acute alcohol poisoningwas established.This mathematical mode can be expressed as x(t)=x_0(1-e~(-kat))-k_bt,which allows calculating the absorpion constant (k_a) arld breakdown rate constant(k_b) for alcohol the curve in dynamic change of the alcohol concentration followingadministration of a large amount of alcohal can be obtained the amount of alcoholin human body [x,(t)] after drinking can be checked out.from the urine Theexperimental study in monkeys showed that the parameters derived from the mathe-matical mode agued witk the results obtained from the experiments

Objective To observe the clinical efficacy of electroacupuncture plus ginger-partitioned moxibustion in treating sudden hearing loss. Method Sixty patients with sudden hearing loss were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by electroacupuncture plus ginger-partitioned moxibustion, while the control group was by electroacupuncture alone. The audiometry was conducted before and after intervention, and the therapeutic efficacy was also evaluated.Result Respectively after the first and second treatment course, the threshold of audibility was significantly changed in both groups (P<0.05); there were significant differences in comparing the threshold of audibility between the two groups (P<0.05). The total effective rate was 80.0% and 90.0% respectively after the first and second treatment course in the treatment group, versus 53.3% and 63.3% in the control group, and the differences were statistically significant (P<0.05).Conclusion Electroacupuncture plus ginger-partitioned moxibustion is an effective approach in treating sudden hearing loss.

Objective To evaluate the abilities of plasma perfusion and plasma exchange to remove blood endotoxin and cytokines from hepatic failure patients. Methods Plasma perfusion and plasma exchange were performed on 7 cases and 10 cases for the treatment of chronic severe hepatitis, respectively. Changes of blood endotoxin and cytokines before and after treatment were analyzed. Results The levels of cytokines and endotoxin in patient blood decreased greatly, but bilirubin decreased slightly after treatment with plasma perfusion. The changes of interleukin 6 were very limited. Compared with plasma perfusion, the removal of bilirubin was higher but that of cytokines was lower after plasma exchange. Conclusion Plasma perfusion can remove cytokines with high efficiency and retard the development of hepatic failure.

Objective: To carry out the native assessment of International Affective Picture System(IAPS) among Chinese older adults.Methods:Altogether 116 Chinese older adults,including 51 male and 65 female,from three communities in Dalian City,aged from 60 to 80 years,rated 60 pictures(positive:25,neutral:12,negative:23) selected from the IAPS in terms of valence,arousal and dominance with Self-Assessment Manikin(SAM).The mean affective ratings were compared to the normative ratings of USA National Institute of Mental Health(NIMH).Result: Reliability analysis indicated that the affective ratings of our sample were stable and highly internally consistent.The affective ratings of Chinese older participants were strongly correlated with the normative ratings of NIMH(r=0.92,0.54 and 0.88 respectively for valence,arousal and dominance,P0.05).Conclusion: IAPS is highly internationally accessible just as the expectation of its designers.However,considering about great differences in many aspects such as culture,social living and age between Chinese aged and NIMH sample,they may have different affective experiences to the same emotional stimuli.Therefore it is necessary to do some revisal before the IAPS is applied to Chinese aged.

Objectives: To determine the regulation effects of recombinant human growth hormone(rhGH) on dipeptide transport(PepT1) in normal and severe scalded rats. Methods: Male Sprague Dawley rats inflicted by 30% total body surface area ( TBSA) Ⅲ degree scalding were employed as the model.The rhGH was used in this study with the dose of 2 U/(kg?d). An everted sleeve of intestine was incubated in Kreb’s solution with radioactive dipeptide ( 3 H Glycylsarcosine, 3 H Gly Sar, 10 ?Ci / ml) at 37℃ for 15 min to measure the effects of uptake and transport of PepT1 of small intestinal epithelial cells in normal and severe scalded rats. Results: The transport of dipeptide in normal rats with injection of rhGH was not significantly increased compared with controls ( P =0.192 6) while the uptake was significantly increased compared with controls ( P = 0.025 3 ). The transport and uptake of PepT1 in scalded rats with injection of rhGH were significantly increased compared with controls( P = 0.008 2 and 0.039 1). Conclusions: The effects of uptake and transport of dipeptide transporters in small intestinal epithelial cells with severe injury were markedly upregulated by rhGH.

CONCLUSION: Sansheng Huatan Decoction combined with chemotherapy is a better treatment for non-small-cell lung cancer as compared with chemotherapy.

Microcirculation dysfunction is involved in the onset of diabetes and its complications.The pathophysiological mechanisms behind the relationship between microcirculation and diabetes are multifactorial.Islet microcirculation dysfunction affects function of islet β cells.Impairment of microvascular vasomotion might be associated with insulin resistance.Microcirculation dysfunction of target organs mediates diabetic complications.

Objective To explore the clinical efficacy of modified single-portlaparoscopic radical prostatec-tomy(LRP) by atransperitoneal or extraperitoneal approach, and the impact of either approach on immune function in patients with prostate neoplasms. Methods The clinical data on 39 patients who had undergoneextraperitoneal LRP(group A) and 20 patients who had receivedtranperitoneal LRP (group B) in our department from January 2012 to December 2015 were retrospectivelyanalyzed. The prostate neoplasms were preoperatively diagnosed as cancer by ultrasound, CT or MRI, and pathological examinations. The clinical stage was T1-T2c , N0M0 in all patients.The efficacy was assessed by surgical duration, intraoperative blood loss, timeto intestinal function recovery, and post-operative hospital stay in both groups. The indicators for immune function including prostate specific antigen (TPSA and FPSA), immunoglobulin (IgG, IgA, lgM, C3, and C4) and T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) in patientswith prostate neoplasms before and after surgery were detected. Results 59 patients were operat-ed successfully, without converting to open approach. The mean surgical duration, blood loss, time to intestinal function recovery, and postoperative hospital stay were (133.8 ± 68.6) min, (75.6 ± 51.3) mL, (2.2 ± 0.7) days, and (14.7 ± 3.6) days in group A, while (159.4 ± 78.1) min, (102.2 ± 70.8) mL, (2.9 ± 1.1) days, and (15.2 ± 4.1) days in group B. There were significant differences between the two groups (P<0.05). After surgery, levels of IgG, IgA, C3, C4, CD3+, CD4+and CD4+/CD8+were significantly higherin group Athan in group B (P < 0.05). There were no significant differences between the two groups in levels of TPSA, FPSA and lgM (P>0.05). Average postoperative follow-up was 15 months (range 3-36) in 36 patients. No recurrence or metastasis was found in all the patients by imaging studies,and no long-term complications were found. Conclusions Extraperitoneal LRP, as compared with tranperitoneal LRP, has clearer vision, fewer effects on abdominal organs, shorter surgical duration, less blood loss, faster postoperative recovery, and better protection of immune function. It is worth popularizing clin-ically.

Objective To investigate the suppressive effect of exogenous carbon monoxide (CO) on abnormal platelet exocytosis and its possible molecular mechanism. Methods Venous blood was collected from healthy volunteers. Platelet-rich plasma (PRP) was isolated from the blood by differential centrifugation. The PRP was randomly divided into five groups by random number table, namely normal control group, lipopolysaccharide (LPS) group (challenged with 10 mg/L LPS), inactively exogenous carbon monoxide releasing molecule 2 (iCORM-2) group (given 10 mg/L LPS + 50 μmol/L iCORM-2 for intervention), exogenous carbon monoxide releasing molecule 2 (CORM-2) 10 μmol/L and 50 μmol/L groups (given 10 mg/L LPS + CORM-2 10 μmol/L or 50 μmol/L for intervention). After 30 minutes, enzyme linked immunosorbent assay (ELISA) was used to determine the platelet-derived growth factor BB (PDGF-BB) and matrix metalloproteinase 2 (MMP-2). Chemical fluorescein method was used to determine the platelet adenosine triphosphate (ATP). Flow cytometer was used to determine the expression of P-selectin. The expressions of Toll-like receptor 4 (TLR4), phosphorylation of protein kinase Cθ (PKCθ) and syntaxin binding protein 1 (STXBP-1) were determined by Western Bolt. The soluble N-ethylmaleimide-sensitive factor-attachment protein receptors (SNAREs) complex formation [syntaxin 2-synaptosomal-associated protein 23-vesicle associated membrane protein 8 (STX2-SNAP23-VAMP8)] mediated by STXBP-1 was determined by immunoprecipitation. Results ① Compared with normal control group, the platelet release of PDGF-BB, MMP-2 and ATP was significantly increased after LPS challenge, and the P-selectin expression of platelet was also obviously up-regulated [PDGF-BB (μg/L): 127.53±1.78 vs. 94.35±5.84, MMP-2 (ng/L): 51.87±9.20 vs. 35.83±3.17, ATP (μmol/L): 1.288±0.056 vs. 0.975±0.010, P-selectin: (3.93±0.19)% vs. (0.44±0.10)%, all P < 0.05]. The increases in platelet release of PDGF-BB, MMP-2 and ATP were suppressed by 10 μmol/L or 50 μmol/L CORM-2 administration, as well as high-expression of P-selectin in a dose-dependent manner [PDGF-BB (μg/L): 114.68±1.35, 97.08±6.14 vs. 127.53±1.78, MMP-2 (ng/L): 32.67±8.00, 24.63±1.63 vs. 51.87±9.20, ATP (μmol/L): 0.999±0.015, 0.965±0.008 vs. 1.288±0.056, P-selectin: (1.95±0.27)%, (0.94±0.11)% vs. (3.93±0.19)%, all P < 0.05]. ② Compared with normal control group, LPS challenge resulted in a significant increase in the expression of TLR4 and the phosphorylation of PKCθ and STXBP-1 [TLR4 (gray value): 1.21±0.38 vs. 0.67±0.06, p-PKCθ (gray value): 1.36±0.20 vs. 0.44±0.03, p-STXBP-1 (gray value): 1.13±0.06 vs. 0.59±0.04, all P < 0.05]. The increases in above parameters were suppressed by 10 μmol/L or 50 μmol/L CORM-2 administration in a dose-dependent manner [TLR4 (gray value): 0.76±0.05, 0.65±0.04 vs. 1.21±0.38; p-PKCθ (gray value): 0.71±0.07, 0.47±0.10 vs. 1.36±0.20; p-STXBP-1 (gray value): 0.56±0.02, 0.48±0.01 vs. 1.13±0.06, all P < 0.05]. ③ Compared with normal control group, the SNAREs proteins in platelet that combined with STXBP-1, including STX2, SNAP23 and VAMP8, were obviously increased after LPS challenge [STX2 (gray value): 1.35±0.06 vs. 0.57±0.04, SNAP23 (gray value): 0.97±0.04 vs. 0.30±0.12, VAMP8 (gray value): 1.37±0.12 vs. 0.77±0.10, all P < 0.05]. The increases in SNAREs complex formation were suppressed by 10 μmol/L or 50 μmol/L CORM-2 administration in a dose-dependent manner [STX2 (gray value): 0.77±0.02, 0.39±0.03 vs. 1.35±0.06, SNAP23 (gray value): 0.41±0.03, 0.22±0.08 vs. 0.97±0.04, VAMP8 (gray value): 0.85±0.07, 0.66±0.07 vs. 1.37±0.12, all P < 0.05]. There was no significant difference in the above mentioned parameters between iCORM-2 group and LPS group. Conclusions LPS-induced abnormal secretion of platelet was suppressed by CORM-2 administration. The mechanism may involve the TLR4/PKCθ/STXBP-1 signaling pathway activation and the SNAREs complex formation.

Objective To explore the effect of tetramethylpyrazine (TMP) on serum cytokines and cardiac function in patients with sepsis myocardial injury.Methods Fifty patients with sepsis myocardial injury were admitted in Hangzhou First People's Hospital from June 2015 to September 2016,and according to the computer generated random number,they were divided into conventional treatment group and TMP treatment group,25 cases in each group.The patients in the conventional treatment group were treated with antimicrobial agents,vasoactive drugs,fluid resuscitation and organ function support,etc.;TMP treatment group was treated with traditional Chinese medicine (TCM) TMP on the basis of routine treatment.TMP 120 mg was added to 250 mL normal saline (NS) for intravenous drip once a day for a therapeutic course of 10 days.Plasma N-terminal pro-B type natriuretic peptidec (NT-proBNP) and serum tmnor necrosis factor-oα (TNF-α) levels were measured before treatment and on 1,5 and 10 days after treatment.Left ventricular internal systolic dimension (LVIDs),fractional shortening (FS) and left ventricular ejection fraction (LVEF) were measured by cardiac ultrasound,3 cardiac cycles were measured and the average results were taken.The intensive care unit (ICU) hospital stay and mortality were calculated in the two groups.Results The levels of NT-proBNP and TNF-α in the two groups after treatment were lower than those before treatment,the differences in the levels were statistically significant between those before treatment and 5 days after treatment in the conventional treatment group [NT-proBNP (ng/L):334.25 ± 36.46 vs.577.72 ± 60.34,TNF-α (ng/L):388.48 ± 43.38 vs.507.74-± 31.63,both P ＜ 0.05],and in TMP treatment group,the levels from 1 day after treatment compared with those before treatment,there were statistical significant differences [NT-proBNP (ng/L):387.44 ± 36.39 vs.571.67-± 56.34,TNF-α(ng/L):403.79 ± 23.20 vs.505.82 ± 31.31,both P ＜ 0.05];the degrees of decrease in TMP treatment group were more obvious than those in conventional treatment group (all P ＜ 0.01).After treatment in the two groups,the LVIDs was decreased gradually,FS and LVEF were increased gradually,reaching the lowest or highest level on 10 days after treatment,and the changes of TMP treatment group were more significant than those in the conventional treatment group,LVIDs and LVEF of the two groups showed statistically significant differences on 5 days after treatment [LVIDs (mm):43.23 ± 5.57vs.48.21 ± 2.29,LVEF:0.47 ± 0.02 vs.0.41 ± 0.02,both P ＜ 0.05],FS on 1 day after treatment showed a statistically significant difference [FS:(23.92 ± 1.81)％ vs.(22.84 ± 1.79)％,P ＜ 0.05].The ICU stay in the TMP group was shorter than that in the conventional treatment group (days:13.16 ± 2.67 vs.16.48-± 3.08,P ＜ 0.05),and the mortality was lower than that of conventional treatment group [20％ (5/25) vs.36％ (9/25)],the difference being not statistically significant (P ＞ 0.05).Conclusions In septic myocardial injury,TNF-α plays an important role;after TMP treatment in patients with myocardial injury caused by viral myocarditis,the serum TNF-α level is decreased showing it has antagonizing TNF-α activity,thus it has protective effect on sepsis myocarditis,improves heart function and the disease prognosis.
