Objective To compare the accuracy of spectrophotometer under different color measurement conditions, so as to provide evidence for clinical color measurement. Methods Spectrophotometer was used to obtain the chromatic value L*, a* and b*(L*:Lightness; a*:Saturation on the red and green axile; b*:Saturation on the yellow and blue axile) of all color pieces in the medium 1/3 of vita classical shade guide under the natural light, incandescent lamp and dark room; the values of chromatism were calculated under different color measurement conditions, and the results were fed to statistical software for analysis. Results The L*, a* and b* values were not significantly different under natural light, incandescent lamp and dark room. The composition ratios of ΔE <1.5 NBS for the natural light and incandescent light, natural light and dark room, incandescent lamp and dark room were 87.50%, 100%, and 93.75%, respectively. Conclusion The measurement accuracy of CM-700d spectrophotometer is high and the environment light has slight effe0ct on the accuracy. The chromatism values of shade guide measured in the dark room is the most true ones, so dark room is recommended for CM-700d spectrophotomete.

Objective: To study the clinical efficacy of Jinghuang tablet (Rhubarb extract tablet, RET) in treating simple obesity. Methods: Four hundred and seventy-two simple obesity patients were randomly divided into 3 pairs of groups: (1) RET-2 treated group (50 cases): treated with RET vs western drug fenfluramine control group (50 cases). (2) RET treated group vs Chinese patent drug Xiaopangmei (XPM) control group with 50 cases randomly divided into each. (3) RET-1 treated group with 137 cases vs blank control of 135 cases. The aim was to observe markedly effective rate, effective rate and side-effect of RET group and fenfluramine and XPM control groups. At the same time, the slimming efficacy of RET-1 treated group and the blank control group were observed. Results: The slimming effective rate of RET is similar to that of fenfluramine (P<0.05), and better than domestically well accepted slimming Chinese patent drug XPM (P<0.05). In comparing RET-1 group with blank control group, the difference of weight loss of the 2 groups after 1 week treatment was 0.93 kg on average, which was significant. Conclusion: The efficacy of RET in treating simple obesity was similar to that of fenfluramine, but the side-effect was obviously less than that of fenfluramine, while the markedly effective rate and effective rate in slimming were significantly better than that of XPM.

OBJECTIVETo explore the molecular mechanism of exocrine immune inflammatory injury of Sjögren's Syndrome and the intervention of Banxia Qinlian Decoction (BQD).

METHODSTotally 18 female NOD mice were randomly divided into the model group, the positive drug group, and the BQD group, 6 in each group. Six female BALB/c mice were recruited as a blank control group. Mice in the blank control group and the model group were gavaged with deionized water at the daily dose of 0.1 mL/10 g body weight. Tripterygium Tablet was administered by gastrogavage to mice in the positive group at the daily dose of 10 mg/kg. BQD was administered by gastrogavage to mice in the BQD group at the daily dose of 60 g crude drugs/kg. After 12 weeks of medication, mice were sacrificed. Their eyeballs were excised and blood collected. Tissues of bilateral parotids and submandibular glands were kept. mRNA transcriptional levels of IL-17, IL-6, type 3 muscarinic acetylcholine receptors (M3R), aquaporin protein-5 (AQP5) were detected by RT-PCR. Expression levels of M3R and AQP5 protein were detected by Western blot. Protein expression levels of IL-17 and IL-6 were detected by ELISA.

RESULTSCompared with the normal group, mRNA transcriptional levels and protein expression levels of IL-17, IL-6, M3R, and AQP5 were significantly up-regulated in the model group (P < 0.01). Compared with the model group, mRNA transcriptional levels and protein expression levels of IL-17, IL-6, M3R, and AQP5 were significantly down-regulated in the positive drug group and the BQD group with statistical difference (P < 0.01, P < 0.05). Compared with the BQD group, mRNA-transcriptional levels of IL-17, IL-6, and M3R, as well as M3R and AQP5 protein expression levels were significantly down-regulated in the positive drug group (all P < 0.01).

CONCLUSIONThe molecular mechanism of BQD in inhibiting SS exocrine neurotoxic injury might be possibly related to regulating Th17/IL-17 immune inflammatory way.

Objective To understand the occurrence of surgical site infection(SSI)following caesarean section,analyze risk factors,implement intervention measures,and evaluate intervention efficacy. Methods All puerperas who underwent caesarean section in the obstetric department of a hospital from January to December 2013 were mo-nitored,investigation were performed in two stages:evaluation stage(January-June,2013)and intervention stage (July-December,2013). Targeted intervention and clinical intervention were combined to intervene the risk factors. Occurrence of SSI,length of hospital stay,and hospitalization expense before and after intervention were compared. Results A total of 1 593 patients with caesarean section were monitored,31(1.95%)had SSI,incidence of SSI in evaluation stage and intervention stage were 3.40% and 0.95% respectively;incidence of SSI before and after inter-vention was significantly different(χ2= 12.02,P<0.01). Univariate analysis on evaluation stage showed that risk factors for SSI in patients with caesarean section were duration of operation≥1 hour,body mass index≥26 kg/m2,intraoperative blood loss ≥300 mL,underlying diseases,premature rupture of membranes,and without antimicro-bial prophylaxis(all P<0.05). In evaluation stage,648 patients received post-operative antimicrobial prophylaxis for>48 hours(n= 395,60.96%);in intervention stage,945 patients received post-operative antimicrobial prophy-laxis for<24 hours(n= 776,82.12%),different time distribution of post-operative antimicrobial prophylaxis in two stages after intervention was compared,difference was statistically significant(χ2= 673.26,P<0.01). The mean length of hospital stay of 31 SSI patients were(13.83±3.26)days,non-SSI patients were(7.06±1.66) days,difference was statistically significant(t= 7.86,P<0.01);the average hospitalization expenses for patients with SSI were(9 044.77±2 649.19)yuan,non-SSI patients were(6 254.73±638.52)yuan,difference was statis-tically significant(t= 4.344,P<0.01).Conclusion Intervention measures for risk factors of SSI after caesarean section can effectively reduce the incidence of SSI in caesarean section.

OBJECTIVETo investigate the molecular mechanism of adiponectin inhibiting activation of hepatic stellate cells in non-alcoholic fatty liver fibrosis.

METHODSThe rat models of non-alcoholic fatty liver fibrosis were successfully established by fat-rich diet administration. The expression of adiponectin mRNA and protein were respectively detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. LX-2 cells were cultured in an adipogenic differentiation mixture to induce quiescent adipocytic phenotypes, and then they were treated with TGFβ1, adiponectin and TGFβ1 + adiponectin, respectively. RT-PCR and Western blot were used to determine the expressions of mRNAs and proteins of a-smooth muscle actin (a-SMA), Collagen, adenosine monophosphate-activated protein kinase (AMPK), inducible nitric oxide synthase (iNOS), and endothelial NOS (eNOS). The results were analyzed using one-way ANOVA, Student-Newman-Keuls test, and linear correlation analysis. A P value of less than 0.05 was considered as statistically significant.

RESULTSIn vivo, with the progress of non-alcoholic fatty liver fibrosis, the model rats gradually showed hepatic steatosis, inflammation, necrosis and fibrosis. Compared with the control group, the level of serum adiponectin (2.49 ± 0.86 vs 5.81 ± 0.87, P < 0.05) and hepatic expressions of adiponectin mRNA and protein (0.26 ± 0.04 vs 0.72 ± 0.08; 0.64 ± 0.07 vs 0.21 ± 0.07, all P < 0.05) were all decreased in the 24th week group, and were negatively correlated with the level of Collagen which increased gradually. In vitro, TGFβ1 could activate quiescent LX-2 cells by decreasing mRNA and protein expression of eNOS (0.30 ± 0.10 vs 0.44 ± 0.08; 0.30 ± 0.09 vs 0.46 ± 0.07, all P < 0.05) and increasing the expression of iNOS (0.53 ± 0.07 vs 0.37 ± 0.04; 0.55 ± 0.07 vs 0.39 ± 0.05, all P < 0.05). Recombinant adiponectin not only maintained the quiescent phenotype of LX-2 cells but also inhibited LX-2 cells activation due to TGFβ1 by increasing the expression of eNOS (0.43 ± 0.08 vs 0.30 ± 0.10; 0.42 ± 0.07 vs 0.30 ± 0.09, all P < 0.05) and phosphorylation of AMPK (0.43 ± 0.07 vs 0.24 ± 0.04, P < 0.05) and decreasing the expression of iNOS (0.44 ± 0.05 vs 0.53 ± 0.07; 0.46 ± 0.07 vs 0.55 ± 0.07, all P < 0.05).

CONCLUSIONSData suggested that adiponectin could play a protective role on the pathogenesis of non-alcoholic fatty liver fibrosis by inhibiting the activation of hepatic stellate cells via up-regulating the expression of eNOS, which might associate with increased phosphorylation of AMPK.
