Objective To explore the correlation between cystatin C (Cys C) and intima-media thickness of carotid artery (CIMT) in patients with hypertension.Methods One hundred and one patients with hypertension (hypertension group) and 54 healthy people (control group) were enrolled in this study.The level of serum Cys C was measured and CIMT was detected by B ultrasound.The correlation between Cys C and CIMT was analyzed.Results The level of Cys C and CIMT in hypertension group were significantly higher than those in control group [(0.92 ±0.21) mg/L vs.(0.85 ±0.20) mg/L,(0.91 ±0.16) mm vs.(0.65 ± 0.15) mm] (P ＜ 0.05 or ＜ 0.01).Multiple linear correlation analysis showed that Cys C and CIMT was positively correlated in total population or hypertension group or control group (r =0.412,0.443,0.315,P ＜0.01).Conclusion Serum Cys C is associated with the degree of hypertension arteriosclerosis,and Cys C may be involved in atherosclerosis.

Objective To investigate neuroprotective function of peroxisome proliferator-activated receptor gamma (PPARγ) agonist, rosiglitazone against reperfusion injury after focal cerebral ischemia in mice model.Methods To establish cerebral isebemia-reperfusion injury mice model, adult male mice underwent 2 hours of middle cerebral artery occlusion followed by 22 hours reperfusion (MCAO/R). One hour before MCAO/R, mice were treated with either vehicle (MCAO/R group) or rosiglitazone (6 mg/kg, rosiglitazone group). 2,3,5-triphenyhetrazolium chloride (TIC) staining was applied to determine the volume of cerebralinfarction.TheneurologicaldeficitwasscoredatZeaLonga 5-pointscale. Myeloperoxidase (MPO) activity was measured in brain tissue as an index of neutrophil accumulation. RT-PCR, immunohistochemistry and Western blot were performed to examine the mRNA and protein expression of pro-inflammatory mediators (ICAM-1, IL-1β and COX-2).Results (1) The volume of cerebral infarction in rosiglitazone group was significantly decreased from that of MCAO/R group ( 29. 1 ± 6. 6 vs 57.8 ± 9. 7 ,t = 5. 980, P < 0. 01 ), and rosiglitazone markedly improved neurological function in treated mice than MCAO/R mice(1.2 +0.4 vs 3.3 ±0.8, t =5.812, P<0.01). (2) Compared with MCAO/R group, MPO activity in the rosiglitazone-treated group was significantly lower ((0. 049 + 0. 005 ) U/g vs (0. 083 ±0. 008) U/g,t =5. 904, P <0. 01 ). (3) The mRNA and protein expression of pro-inflammatory mediators (ICAM-1, IL-1β and COX-2) in rosiglitazone group were also significantly decreased from those in MCAO/R group, as demonstrated by RT-PCR (0.313 ±0.024, 0.205 ±0.007, 0.359 ±0.060, t = 7.464, 19.656, 29.319, P <0.01, respectively) and Western blot (0.274±0.014, 0.205±0.025, 0. 146±0.015, t=79.909, 21.392, 95. 105, P<0.01, respectively). ConclusionThe present study suggests that PPARγ agonist, rosiglitazone, has neureprotective properties to cerebral ischemia-reperfusian injury and that the protection is partially mediated via anti-inflarmmatory actions.

Objective To investigate the clinical effect of shuxuening treatment on organophosphorus pesti-cide poisoning with toxic myocarditis.Methods 60 patients with organophosphorus toxic myocarditis were selected in our hospital as the research subjects,and 60 cases were divided into two groups:observation group(n =30) and control group(n =30).Control group was given conventional treatment,treatment group was given shuxuening injec-tion 14 days on the basis of conventional treatment.After treatment,creatine kinase isoenzyme (CKMB),troponin (TNI),interleukin 6 (IL -6) and cholinesterase(ChE) were compared,and the changes of clinical symptoms were observed at the same time.Results There was no significant difference between the observation group and the control group(χ2 =0.630,P =0.730).The TNI,IL -6,CKMB could reflect the severity of myocardial injury in patients with different degrees of organic phosphorus poisoning,TNI,CK -MB,IL -6 increased with the degree of poisoning,the differences were statistically significant(F =11.863,4.512,3.774;P =0.000,0.015,0.029).After treatment for 4, 9,14 days,TnI,CK,CK -MB,levels of IL -6 in the two groups were recovered,but the recovery levels of TnI,CK -MB and IL -6 of the observation group significantly better than the control group,the differences were statistically sig-nificant(Fourth days,t =8.125,5.128,10.461;P =0.000,0.001,0.000;Ninth days,t =5.464,4.674,9.510;P =0.001,0.002,0.000,t =6.162,8.248,5.523;P =0.000,0.000,0.001).Conclusion Conventional treatment combined with shuxuening in the treatment of organophosphorus pesticide poisoning with toxic myocarditis has better therapeutic effect,it is worthy of promotion.

Objective To explore the mechanisms of posterior pilon fractures and evaluate the curative effects of different types of fixation on the treatment of posterior pilon fractures.Methods We included in this retrospective study 20 patients with posterior pilon fracture who had been treated from January 2012 to January 2015 at our department.They were 10 men and 10 women,from 23 to 77 years of age (average,50.6 years).According to the classification by Yu Guangrong,5 cases belonged to type Ⅰ,3 to type Ⅱa,4 to type Ⅱb,and 7 to type Ⅲ.One was not indentified because of lacking CT examination.The mechanisms included ground level fall in 2 cases,motor vehicle accident in 7,fall off stairs in 5,sport injury in 2,fall from a bike in one and fall from a height in 3.More than 25％ of the articular surface was involved in 13 patients.Syndesmosis injury was identified in 6 patients by Cotton test during operation.Internal fixation varied accordingly.We recorded the mechanism,classification,proportion of the articular surface involved (more or less than 25％),and syndesmosis injury to figure out the characteristics of posterior pilon fractures.We used the Burwell-Charnley radiographic criteria to assess the postoperative reduction of the articular surface,and the Olerud-Molander scoring scale and visual analogue scale (VAS) to assess the ankle function.The curative effects of different types of fixation on the treatment of posterior pilon fractures were compared.Results Of the 20 patients,17 were available for follow-up for 6 to 36 months (average,17.8 months).Two patients received reoperation because of implant failure after cannulated screw fixation from anterior to posterior.The Burwell-Charnley radiographic evaluation revealed 12 anatoinical reducations and 8 fair reductions.The mean Olerud-Molander score for the 17 patients at the final follow-ups was 81.5 (range,from 35 to 100) and the mean walking VAS was 1 (from 0 to 3).Conclusions Posterior pilon fractures are mostly caused by medium to high energy violence,resulting from a combination of rotational and vertical forces.Since there is a high risk of implant failure,the cannulated screw fixation from anterior to posterior is not recommended.Good clinical outcomes are observed in the cannulated screw fixation from posterior to anterior and the plate/cannulated screw fixation for posterior pilon fractures.

This article was aimed to study the effect ofXiao-Qing-LongDecoction (XQLD) on plasma AngⅡ, ALD, Na+-k+-ATPase content, and plasma AT1 and AT2 mRNA expressions in Cor pulmonale rats, in order to further explore the mechanism of ventilating lung qi for diuresis. A total of 60 Wistar rats were randomly divided into the normal group, model group and XQLD, with 20 rats in each group. The enzyme-linked immunosorbent assay (ELISA) method was used to determine the AngⅡ, ALD and Na+-k+-ATPase content. The fluorescence quantitative PCR was used to detect the AT1 and AT2 mRNA expression. The results showed that compared with the normal group, the AngⅡ, ALD and Na+-k+-ATPase contents in the model group were significantly increased (P< 0.05, orP< 0.01). Compared with the model group, the AngⅡ, ALD and Na+-k+-ATPase contents in the XQLD group were obviously decreased (P< 0.05). Compared with the normal group, AT1 mRNA expression was increased; and AT2 mRNA expression was decreased in the model group (P<0.05, orP< 0.01). Compared with the model group, AT1 mRNA expression was decreased; and AT2 mRNA expression was increased in the XQLD group (P < 0.01). It was concluded that XQLD can effectively regulate the AT1 and AT2 mRNA expressions, influence ALD content to ventilate lungqi for dieresis.

Objective To study the effect of Shuanghuanglian injection on CRP, PCT and IL-6 in pneumonia children.Methods 68 cases of pneumonia children were selected and divided into the control group and the experiment group.33 case in the control group and 35 cases in the experiment group.The two groups were treated with conventional symptomatic treatment and anti infection treatment for the two groups were implemented routine symptomatic treatment and anti infection treatment.The control group were treated with cefotaxime sodium injection, the experiment group were treated on the base with Shuanghuanglian injection.CRP, PCT and IL-6 in serum were compared before and after the treatment.Results Compared with the control group, the level of CRP in serum was lower(P<0.05), the level of PCT in serum was lower(P<0.05), the level of IL-6 in serum was lower(P<0.05).Conclusion Shuanghuanglian injection has a good clinical effect on children’s pneumonia.It is speculated that the mechanism is related to the decrease of serum CRP and IL-6 level.
