Objective To evaluate the pathogenesis and disease progression by detecting the expression of Serum High mobility group protein 1 (HMGB1) and TLR2 in monocytes of patients with systemic lupus erythematosus (SLE).Methods Forty patients with SLE were selected randomly,20 patients were in active disease group and others were in stable disease group.The expression of HMGB1 in the serum of these cases were detected by enzyme linked immunosorbent assay (ELISA) and TLR2 on CD14+ monocytes in the peripheral blood were detected by FCM.The correlation between these indexes and clinical,laboratory indexes about SLE were analyzed using one-way ANOVA,and Kruskal-Wallis test.Results The expression levels of HMGB-1 in serum was [(48.9±11.3) μg/L] in the active group,while that was [(14.8±1.9) μg/L] in the stable group was,and [(13.5±3.6) μg/L] in the control group.HMGB1 in the active SLE group was significantly higher (P＜0.05) when compared with that of the stable and control group.The expression of TLR2 in the peripheral blood mononuclear cells was [(96.7±1.3)％] in the active group,[(83.5±9.1)％] in the stable group,and [(83.3±9.9)％] in the control group TLR2 in the active SLE group was up-regulated when compared with the stable and control groups (P＞0.05).There were positive correlation between the serum levels of HMGB1and TLR2 in the peripheral blood mononuclear cells (r=0.551,P＜0.05).Conclusion The expression levels of HMGB-1 in serum and the expression of TLR2 in peripheral blood mononuclear cells may participate in the pathological processes of SLE.

Objective To investigate the therapeutic effect of topical corticosteroids injection and systemic application in the treatment of sudden hearing loss.Methods Total of 58 patients with sudden hearing loss were ran-domly divided into two groups.The systemic application group:dexamethasone (DEX)was applied by intravenous injection in dose of 10mg ×3d,followed by 5mg ×4d.And the postauricular injection group:methylprednisolone sodium succinate of 40mg was injected into cortical bone of mastoid region every three days,until hearing back to normal,or 15 days.SPSS 13.0 software was used to analyze the data.Results The total effective rate of systemic application group was 67.7%,the total effective rate of postauricular injection group was 64.7%.There was no statistical differ-ence between the two groups (χ2 =2.58,P =0.316).The recovery rate in cases with postauricular injection group was significantly increased in comparison with the systemic application group,but no statistical difference between the two groups(t =2.71,P =0.062).Patients with hearing loss in low frequencies(250Hz,500Hz),the recovery rate in cases with postauricular injection group was significantly increased in comparison with the systemic application group (t =3.82,P =0.031;t =3.26,P =0.042).Conclusion Postauricular topical injection and systemic application of glucocorticoids in the treatment of sudden hearing loss are all have good curative effect.Systemic application is select-ed by conventional treatment,and topical injection has a better effect in the hearing loss of low -middle frequencies.

Objective To investigate the effect of modified suture on the maternal skin healing, scar healing and satisfaction to cesarean section. Methods A total of 244 cases of cesarean section in our hospital from January 2015 to January 2016 were randomly collected and divided into observation group (n=143) and control group (n=101). Patients in the observation group were treated with the modified suture method, and the control group was given the conventional method to suture the skin. The VAS score, suture time and complication rate were observed in the 2 groups. Results The VAS scores were significantly lower at one week and one month after operation (1.15±0.43 and 0.07±0.01, respectively) than those of the control group (1.40±0.51 and 0.13±0.03, respectively, P<0.05). The suture time were significantly shorter in the observation group (5.12±0.95) than those of control group (7.28±0.83, P<0.05). Postoperative complication rate was significantly lower in observation group (2.80%) than that of control group (9.90%, P<0.05). The comfort level to incision and satisfaction rate to scar were significantly higher (94.41% and 95.10%, respectively) than those of control group (83.17% and 87.13%, respectively). The average thickness of scars at day 90 and day 180 after operation were significantly less in the observation group [(2.14±0.32) mm and (3.08±1.02) mm, respectively] than those of the control group [(3.10±0.48) mm and (5.22±1.10) mm, respectively, P<0.05)]. Conclusion The improved suture method after cesarean section has the advantages of shorter suture time, less poor wound healing, higher maternal satisfaction rate.

Object To study the expression of miRNA-146a in sepsis-induced acute lung injury (ALI) patients and its effect on the inflammation in mouse models.Methods miRNA-146a expression in peripheral blood was determined in sepsisinduced ALI patients and healthy volunteers by qRT-PCR.Sepsis-induced ALI mouse model were reproduced by LPS treatment and miRNA-146a mimic,miRNA-146a NC and miRNA-146a inhibitors were injected through trachea.The expressions of miRNA-146a,TNF-α,IL-1β and COX-2 mRNA were determined by qRT-PCR 24h after the intervention.Results The miRNA-146a expression in peripheral blood significantly increased in severe sepsis with ALI patients,compared with the control subjects.For mouse model,the expressions of TNF-o,IL-1β and COX-2 mRNA significantly decreased in miRNA-146a group,while increased in miRNA-146a inhibitor group compared with miRNA-146a NC group (P＜0.05).The TNF-α and IL-1β expressions significantly decreased in miRNA-146a inhibitor+COX-2 inhibitor group compared with miRNA-146a inhibitor group (P＜0.05).Conclusion MiR-146a treatment can effectively alleviate the lung inflammation in sepsis-induced ALI mice.

Objective To evaluate the effect of remifentanil on cell apoptosis during renal ischemia-reperfusion (I/R) in rats.Methods Seventy-five male Sprague-Dawley rats,weighing 220-250 g,were randomly divided into 3 groups (n =25 each):sham operation group (group S),I/R group,and remifentanil group (group R).Renal ischemia was induced by occlusion of the bilateral renal arteries for 45 min followed by reperfusion in groups I/R and R.Remifentanil was infused at 1.0 μg· kg-1 · min-1 via the caudal vein starting from 15 min before ischemia until 30 min of reperfusion in group R,while the equal volume of normal saline was given instead of remifentanil in groups S and I/R.At 15 min before ischemia (T0) and 3,6,12,24 h of reperfusion (T1-4),5rats were anesthetized and sacrificed,and renal specimens were obtained to detect the apoptotic rate and expression of Bax and Bcl-2 protein (by flow cytometry) and mRNA (by RT-PCR).The ratios between Bcl-2/Bax protein and mRNA expression were calculated.The pathological changes of renal tubules were scored.Results Compared with group S,the pathological scores and apoptotic rate were significantly increased at T1-4,and ratios between Bcl-2/Bax protein and mRNA expression were increased at T1,2,while decreased at T3,4 in groups R and I/R (P ＜0.01).Compared with group I/R,the pathological scores and apoptotic rate were significantly decreased at T1-4,while the ratios between Bcl-2/Bax protein and mRNA expression were increased in group R (P ＜ 0.05 or 0.01).Compared with the baseline value at T0,the pathological scores and apoptotic rates were significantly increased at T1 4,and the ratios of Bcl-2/Bax protein and mRNA expression were increased at T1,2,while decreased at T3,4 in groups R and I/R (P ＜ 0.01).Conclusion Regulation of Bcl-2/Bax expression and inhibition of cell apoptosis in renal tissues are involved in the mechanism by which remifentanil reduces renal I/R injury in rats.

Objective To investigate the impact of percutaneous coronary interventional (PCI) on the inflammatory indices and postoperative vascular restenosis.Methods This study involved 90 patients undergoing PCI procedures for Coronary artery disease (CAD) compromising a single coronary artery.Fourty healthy individuals with normal findings by coronary angiography were selected as the control group.Before and after PCI or coronary angiography,plasma hs-CRP and IL-6 were measured in all the subjects by immunonephelometry and enzyme-linked immunosorbant assay (ELISA),respectively.Results (1) In the CAD patients,the plasma hs-CRP level was significantly elevated after PCI as compared with the preoperative level((18.69 ±5.14) mg/L vs (14.45 ± 4.32) mg/L,t =1.42,P ＜ 0.01),whereas in the control group,the hs-CRP level underwent no significant changes after coronary angiography((13.59 ±5.99) mg/L vs(12.46 ±5.35) mg/L,t =1.25,P ＞ 0.05).(2) PCI procedures also resulted in significant elevation of plasma IL-6 level in the CAD patients((1.87±0.45) pg/L vs (1.35 ±0.39) pg/L,t =1.33,P＜0.01),but in the control group,IL-6 showed no significant variation after coronary angiography ((1.32 ± 0.41) pg/L vs (1.21 ± 0.38)pg/L,t =1.16,P ＞ 0.05).We observed significant difference of hs-CRP and IL-6 levels between the CAD patient group and the control group (t =4.96,6.61 respectively,P ＜ 0.01).Conclusion Plasma hs-CRP and IL-6 are elevated in CAD patients following PCI procedures.But the roles of elevated hs-CRP and IL-6 in the vascular restenosis following the procedures need further investigation.

This study was aimed to observe the antipyresis and cholagogue effect of theFructus Gardeniae-Fructus Forsythiaeherb couple in order to explore the possible pharmacodynamic mechanism. Dry yeast suspension was subcutaneously injected into the back of rat to establish the fever model. The freeze-dried powders ofF. Gardeniae,F. Forsythiae, andF. Gardeniae-F. Forsythiaeherb couple were prepared. They were dissolved in the water for intragastric administration. SD rats were randomly divided into the normal group, model group, positive control group and Chinese medicine group. The Chinese medicine group was subdivided into the group ofF. Gardeniae,F. Forsythiae, andF. Gardeniae-F. Forsythiaeherb couple. The concentration of herbal water extract was 10 mL·kg-1 (which equaled to 3 g·kg-1 of a single crude herb). The concentration of positive control was 10 mL·kg-1. Intragastric administration of equal amount of normal saline was given to the blank group and the model group. Except rats in the normal group, rats in other groups were subcutaneously injected with 10 mL·kg-1 of 15% dry yeast suspension on the back of to establish the fever model. Electronic thermometer was used to record the body temperature of rats at 0, 1, 4, 5, 6, 7 and 8 h after the injection, respectively. Meanwhile, bile was collected from 1-1, 1-2, 2-4, 4-6, 6-8, 8-12, 12-24 h, respectively. Observation was given on changes of body temperature and bile amount of rat. The results showed thatF. Gardeniae,F. Forsythiae, andF. Gardeniae- F. Forsythiaeherb couple had certain effect to reduce the body temperature of rats. The temperature-reducing effect of the combination of both herbs was better than a single herb. TheF. Gardeniae -F. Forsythiae herb couple can reduce the body temperature of fever rat (P < 0.05, orP < 0.01). It had a little effect on the body temperature of normal rat. TheF. Gardeniae - F. Forsythiaeherb couple can promote the bile secretion, which was better than the single using of F. Gardeniae (P < 0.05). It was concluded that theF. Gardeniae - F. Forsythiaeherb couple had better temperature-reducing effect than the using of a single herb; however, there was no significant difference. But it had obvious effect on the promotion of bile secretion, which indicated the strengthening of cholagogue effect.

Objective To observe the effect of Shoutaiwan on the expression ofα-enolase in the decidua tissue of recurrent abortion mice. Methods The abortion-prone CBA/J × DBA/2 matings were established as the model of recurrent abortion and the nonabortion-prone CBA/J×BALB/C matings were used as the model of normal pregnancy. The model of recurrent abortion CBA/J × DBA/2 of pregnant mice were randomly divided into model group and Shoutaiwan high-, medium-, low-dose groups, pregnant mice of every group were orally administrated in different doses. On the 14th day of pregnancy, the mice were killed. The expression ofα-enolase was detected by using immunohistochemical method and Western Blot. Results α-enolase expression in the model group was significantly higher than the normal pregnancy group (P<0.01). Compared with the model group, Shoutaiwan low-, medium- and high-dose group significantly decreasedα-enolase expression of pregnant mice (P <0.01). Compared with high-dose group, Shoutaiwan medium-and low-dose group showed no significant difference (P>0.05). Conclusion Shoutaiwan could down-regulate the expression ofα-enolase in the decidua tissues of recurrent abortion mice, which may be one of its mechanisms of preventing miscarriage.
