Objective To study the effect of skin stratum corneum on transdermal absorption characteristic of Sinomenine Liposome Patch. Methods The normal and stripped stratum corneum skin of back and abdomen was used to study the transdermal absorption characteristic by Franz method. The transdermal absorption sample was taken at the preset sampling time point. The sample content was determined by HPLC. The cumulative transdermal amount of per unit area was fitted with sampling time point, the transdermal rate constant (J value) was selected as comparative standard. Results The transdermal rate constant (J) of skin with stratum corneum stripped increased obviously than that of the normal skin, so was the released rate constant. Conclusion The skin stratum corneum has an notable impact on transdermal absorption characteristic of Sinomenine Liposome Patch. When the skin of experimental animal being prepared, the integrality should be paid more attention.

Aim To evaluate the clinical application of propofol in critical patients with mechanical ventilation. Methods22 patients with mechanical ventilation after major operation were randomly divided into control group and propofol group patient in the propofol group were continually transfused with propofol by micro pump. Clinical manifestations, blood pressure, heart rate and the concentration of epinephrine (E)and norepinephrine (NE) in patients of both groups were observed. Results The patients in propofol group were all in sleeping state, while those in the control group had evidently higher blood pressure,heart rate and the concentration of epinephrine and norepinephrine after wearing of ventilator. There was a significant difference between the two groups ( P<0.05) . Conclusion Propofol can make the critical patients quiet and inasleepingstate,inhilitthereleaseof epinephrine and norepinephrine, which rescdt in hemodynamic stability.

Albendazole and mebendazole were comparatively evaluated in 22 adult patients for their in vivo effects on hookworm eggs. Both drugs were given 200mg twice daily for three consecutive days. Stool specimens wore collected before treatment and during the following five days. The Stool egg count was carried out by Stolls method and each specimen was also cultured by Hara-da-Mori technique for at least eight days. The mean pre-treatment percentage of incubated hookworm eggs that developed to larvae was 75.3% in albendazole group and 68.8% in mebendazole group respectively. One day following the initiation of treatment the mean percentage was remarkably reduced to 0.25% in albeadaole group and no eggs developed to larval stage beyond day 1. 0ne day and two days following the initiation of treatment the mean percentage was 16.23% and 23.13% respectively in mebendazole group. No eggs developed to larval stage on day 3 and thereafter. Albendazole seems to have better ovicidal effect than mebendazole.Albendazole and mebendazole were also comparatively evaluated in 123 adult patients with single or mixed infections of hookworm, ascarisis, and trichuris. A single dose of 400mg was used for both drugs. 2 and 4 weeks after treatment, their stools were examined by brine flotation technique. The hookworm eggs negative conversion ratss 2 weeks after treatment were 78.8% and 26.4% respectively in albeadazole and mebendazole group; while those 4 weeks after treatment were 74.1% and 25.5% respectivley. For ascariasis, the eggs negative conversion rates were 98.0% and 92.0% respectively. For trichuriasis, the negative conversion rates were only 20.6% and 27.7% respectively

Objective To discuss influence factors on prognosis of the patients with capillary leak syndrome (CLS) in ICU.Methods The clinical data of 191 patients with CLS in ICU were reviewed,and the patients were divided into three groups according to prognosis:death group ( n =37),cured group ( n =132) and non-healed group (n =22).The clinical data of death group were compared with those of cured group at admission,during the course of CLS and before discharging from hospital.Results Compared with the cured group,the central venous pressure and serum albumin decreased ( P < 0.01 ) ; anion gap,triglycerides,pressure adjusted heart rate (PAHR) and oxygenation index were lower ( P < 0.01 or P < 0.05) ; serum glucose and SIRS score increased ( P < 0.01 ) in death group.There was higher rate of poor renal function at admission in death group than that in other groups ( P < 0.01 ).There were more many patients treated with intravenous administration of hydroxyethyl starch,ulinastatin and continuous blood filtration therapy in cured group than those in other groups ( P < 0.05).Conclusions The factors influencing the outcomes of the patients with CLS were hypovolemia,severe hypoproteinemia,interior milieu disorder,malnutrition,hypoxemia,renal injury and severe systemic inflammatory response.The outcomes of patients with CLS in ICU could be improved by using hydroxyethyl starch,ulinastatin and continuous blood filtration therapy.

Objective To study the effects of pulse high volume hemofiltration (PHVHF) on the changes of Th17 cells (T helper 17 cells) and CD4 + CD25 + reguratory T cells (Treg cells) in peripheral blood of patients with sepsis and to evaluate the clinical value of this intervention. Methods The patients were included in this prospective study as per the criteria of sepsis set by America Chest Physicians College/America Society for Critic Care Medicine in 1992. The patients were excluded: ① immune system disorder, ② acute stroke, ③ myocardial infarction, ④ virus hepatitis,⑤ human immunodeficiency virus infection, ⑥ under immunosuppressive therapy. Forty patients (24 males, 16 females, aged from 25 to 75years) with sepsis in ICU were enrolled from January. 2008 to November. 2010. According to the severity of disease, the patients were divided into three groups; moderate sepsis group (n = 14, 8 males, 6 females) , severe sepsis group (n = 15, 9 males, 6 females) , and septic shock group (n = 11, 7 males, 4 females). The initially clinical data of three groups were comparable. Twenty healthy individuals served as controls. According to the mode of treatment, forty patients were also divided into two groups: conventional treatment group (group A, n= 15) in which patients were treated without PHVHF within 5 days after admission and trial group (group B, n=25) in which patients were treated with pulsed high volume hemofiltration (PHVHF) within 5 days after admission. In group B, high volume hemofiltration (70 mL · kg-1 · h-1) was given to patients for 6 ~ 8 hours, and then conventional continuous vein - vein hemofiltration (35 mL · kg-1 · h-1) for 16 ~ 18 hours. The total length of period for continuum blood scavenging was 24 hours as one cycle. The interval between two cycles of blood scavenging was 24 hours. The changes of Th17 cells and CD4+ CD25 + Treg cells of 40 patients were detected with flow cytometry on the 1st day and the 5th day after admission. The data were analyzed by using SPSS version 13. 0 software. Measurement data were analyzed with Paired-samples t-test, independent-samples t-test or one way ANOVA . Ratio of small samples was compared with fisher's exact test, and the correlation was analyzed by using Pearson correlation analysis. Results The rates of Th17 cells were( 0.91 ±0.38)%, (2.09 ±0. 53)% , (3.90 ±0. 80)% , and ( 1. 85 ±0.35)% in control, moderate sepsis, severe sepsis, and septic shock groups, respectively, while the rates of CD4+ CD25+ Treg cells were (0.39 ±0.23)%, (1. 72 ±0. 59)% , (2.72 ±0. 22)% , and (3. 55 ±0. 51)% , respectively. The rate of Thl7 cells on the 1st day was higher in severe sepsis group than that in other two groups ( P < 0. 05 ) without significant difference between septic shock and moderate sepsis groups ( P > 0. 05). Moreover , the rate of CD4+ CD25 + Treg cells was up - regulated on the 1st day in the following order from high to low: septic shock group > severe sepsis group > sepsis group (P < 0.05). The rates of Th17 cells and CD4 + CD25 + Treg cells in patients of group B decreased in greater degree than that did in patients of group A (P < 0.05 ). Conclusions The changes of Th17 cells and CD4 + CD25 + Treg cells may play an important role in pathogenesis of sepsis, and the pulsed high volume hemofiltration may be one of the effective treatments for the patients with sepsis by regulating the rates of Thl7 cells and CD4 + CD25 + Treg cells.
