Objective To observe the long-term result of brachial plexus injury.Methods41 cases of brachial plexus injury were divided into the non-operation group (n=11), neurolysis group (n=17), never repair group (n=13). Retrospective analysis of the charts and follow-up survey of the functional recovery of shoulder joint and elbow joint were carried out. Gilbert score and Mallett score were adopted at the follow-up.ResultsIn the non-operation group, 9 cases were graded as excellent, 1 case as good, 1 case as bad. In the neurolysis group, 2 cases were graded as excellent and good. In the never repair group, 2 cases of shoulder joint obtained excellent, 4 cases of elbow joint were grade as good.ConclusionThe simple surgical result of brachial plexus injury is not satisfactory, it should be combined with postoperative rehabilitation.

The aim is to study the intestinal absorption of different combinations of active compounds out of Gegenqinlian decoction. Rat single pass intestinal perfusion model with jugular vein cannulated was used. Samples were obtained continuously from the outlet perfusate and the mesenteric vein. The levels of puerarin, daidzin, liquilitin, baicalin, wogonoside, jatrorrhizine, berberine and palmatine were determined by LC-MS/MS and their permeability coefficients were calculated. The results showed that Glycyrrhiza could promote the absorption of the active ingredients in Pueraria which is the monarch herb; meanwhile, Pueraria also played a role in promoting the absorption of liquilitin. Based on the Gegenqinlian decoction and the different combinations experiments, the results concerning the absorption of baicalin and wogonoside were as follows. For baicalin, Pueraria and Glycyrrhiza could promote its absorption and the effect of Pueraria was more obvious. For wogonoside, Pueraria could also promote its absorption, while Glycyrrhiza played a opposite role. Pueraria and Glycyrrhiza both played a part in promoting the absorption of jateorhizine, berberine and palmatine, the effective compounds in Coptis.

This study was aimed to observe the influence on angiogenesis factor and expression of its receptor protein on estrogen-induced uterine fibroids rat models with Y i-Qi Xiao-Zheng (YQXZ) method, in order to explore the mechanism of this method in the inhibition of angiogenesis in the treatment of uterine fibroids. Castration and estro-gen-induced method were used in the establishment of guinea pig uterine fibroids rat model. And then, different doses of Chinese medicine of YQXZ method were given. The immunohistochemical method was used in the detection of microvessel density (MVD) and vascular endothelial growth factor (VEGF) protein expression of the uterine tissues. The RT-PCR method was used to detect the expression of VEGFR1 mRNA and VEGFR2 mRNA. Then, statistical analysis was given on indexes mentioned above. The results showed that compared with the normal control group, ex-pression of MVD, VEGF and VEGFR of uterine muscle tissues in the model group was significantly higher (P <0.01). Compared with the model group, Chinese medicine group of different doses showed different reducing. Among them, the high-dose group was the most obvious one. It showed that the high-dose Chinese medicine of YQXZ group was able to significantly inhibit the expression of MVD, VEGF and theirs receptors. It was concluded that YQXZ method can antagonize proliferation of the leiomyoma cell by inhibiting angiogenesis. Therefore, it may be one of the mechanisms of this method in the treatment of uterine fibroids.

Objective To determine the role of activated status of peroxisome proliferator-activated receptorγ/nuclear factor-κB ( PPAR-γ/NF-κB ) in coagulation disorders induced by sepsis. Methods Forty male Sprague-Dawley ( SD ) rats were randomly divided into four groups, n = 10 in each group: control group, lipopolysaccharide ( LPS ) challenged group, rosiglitazone ( ROSI, selective agonist of PPAR-γ) pretreatment group, and GW9662 ( PPAR-γ antagonist ) pretreatment group. The sepsis model was reproduced by injection of 6 mg/kg LPS via sublingual vein, and the rats in control group were injected with 2 mL/kg normal saline. The rats in ROSI pretreatment group were given 0.3 mg/kg ROSI by sublingual venous injection followed by injection of LPS 30 minutes later;and in GW9662 pretreatment group rats were given 0.3 mg/kg GW9662 by sublingual venous injection followed by 0.3 mg/kg ROSI 15 minutes later, followed by injection of LPS 30 minutes later. Blood was collected at 4 hours after LPS administration, and the expressions of PPAR-γ and NF-κBp65 in peripheral blood mononuclear cell ( PBMC ) were determined with immunocytocheminal technique and graph analysis. Plasma prothrombin time ( PT ), activated partial thromboplastin time ( APTT ), fibrinogen ( FIB ), and D-dimer were determined simultaneously. Results① PPAR-γ/NF-κB pathway: the expressions of PPAR-γ and NF-κBp65 were lowered in control group, and they were expressed in cytoplasm. In LPS challenged group the expression of PPAR-γ ( gray value ) was slightly increased but with no significant difference as compared with control group ( 111.01±4.06 vs. 98.46±5.99, P >0.05 ). In ROSI pretreatment group the expression of PPAR-γ( gray value ) was significantly higher than that in LPS challenged group ( 214.38±5.79 vs. 111.01±4.06, P<0.01 ), with dislocation into nuclei. In GW9662 pretreatment group the expression of PPAR-γ ( gray value ) was lowered but without significant difference compared with that of control group ( 44.21±2.64 vs. 98.46±5.99, P>0.05 ). In LPS challenged group the expression of NF-κBp65 ( gray value ) was significantly higher than that in control group ( 249.48±6.86 vs. 105.81±10.19, P < 0.01 ), and it was translocated into the nuclei. In ROSI pretreatment group the expression of NF-κBp65 ( gray value ) was significantly lower than that in LPS challenged group ( 102.47±8.05 vs. 249.48±6.86, P < 0.01 ), and it lied in cytoplasm. In GW9662 pretreatment group the expression of NF-κBp65 ( gray value ) showed no significant difference as compared with that of LPS challenged group ( 214.84±7.91 vs. 249.48±6.86, P>0.05 ).②Coagulation:compared with control group, PT and APTT were significantly prolonged, FIB was significantly decreased, and D-dimer was significantly increased in LPS challenged group [ PT ( s ):18.32±2.03 vs. 12.22±1.38, APTT ( s ):40.05±2.72 vs. 26.64±2.73, FIB ( g/L ): 1.65±0.51 vs. 3.60±0.37, D-dimer ( mg/L ): 2.58±0.73 vs. 0.37±0.06, all P < 0.01 ]. Compared with LPS challenged group, APTT and PT were significantly shortened, FIB was significantly increased, and D-dimer was significantly lowered in ROSI pretreatment group [ PT ( s ):13.93±1.67 vs. 18.32±2.03, APTT ( s ):30.29±0.86 vs. 40.05±2.72, FIB ( g/L ):3.18±0.69 vs 1.65±0.51, D-dimer ( mg/L ):0.40±0.12 vs. 2.58±0.73, all P<0.01 ]. All parameters in GW9662 pretreatment group showed no significant difference as compared with those of LPS challenged group. Conclusions PPAR-γagonist ROSI may ameliorate coagulation disorders in septic rats. PPAR-γ/NF-κB transduction pathway plays an important role in septic coagulopathy.

To analyse and compare the characteristics of the intestinal absorption of puerarin, baicalin, berberine and liquiritin in different combinations of Gegenqinlian decoction based on pharmacokinetic parameters, a sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was applied for the quantification of four components in rat's plasma. And pharmacokinetic parameters were determined from the plasma concentration-time data with the DAS software package. The influence of different combinations on pharmacokinetics of four components was studied to analyse and compare the absorption difference of four components, together with the results of the in vitro everted gut model and the rat single pass intestinal perfusion model. The results showed that compared with other combinations, the AUC values of puerarin, baicalin and berberine were increased significantly in Gegenqinlian decoction group, while the AUC value of liquiritin was reduced. Moreover, the absorption of four components was increased significantly supported by the results from the in vitro everted gut model and the rat single pass intestinal perfusion model, which indicated that the Gegenqinlian decoction may promote the absorption of four components and accelerate the metabolism of liquiritin by the cytochrome P450.

Objective To evaluate the capacity of atopy patch test in diagnosis of food allergy in children with atopic dermatitis (AD).Methods Egg and milk,as the most common food allergens among Chinese children,were employed in this study.Skin prick test (SPT) and atopy patch test (APT) with fresh egg and milk were carried out in 68 children with AD.Oral food challenges in an open style were performed to confirm the diagnosis of food allergy.Resuits Of these patients,58(85.3%)were sensitive to egg,40(58.8%)to milk and 34(50.0%) to both.Of 98 patients with positive challenge,47 showed late response,10 immediate reactions.and 41 mixed reactions.The sensitivity,specificity,positive predictive value (PPV),negative predictive value (NPV) and the agreement with food challenges in diagnosis of egg/milk allergy were 96.6%/67.5%.90.0%/82.1%,98.2%/84.4%,81.8%/63.9% and 95.6%/73.5%,respectively for APT alone,37.9%/30.0%,100%/89.3%,100%/80.0%,21.7%/47.2% and 47.1%/54.4%,respectively for SPT alone.APT was found to be more sensitive in diagnosis of late-phase reactions than SPT (P<0.01).No significant difference was found in the sensitivity between APT alone and the combination of APT and SPT in parallel algorithm for diagnosis of egg or milk allergy (x2=0.509,0.549,both P>0.05) or in the specificity between APT alone and that in serial algorithm( P=1.000;x2=3.514,P>0.05).Conclusions APT is superior to SPT in diagnosis of late responses to food,and the combination of SPT and APT does not facilitate the diagnosis of food or milk allergy compared with APT alone.

Objective To evaluate the significance of human interleukin-31(IL-31)in the pathogenesis of atopic dermatitis and its correlation with pruritus in patients with atopic dermatitis(AD).Methods Twenty-two children with mild to severe atopic dermatitis and 22 age-matched healthy controls were included in this study.Patients and controls were randomly and equally assigned into stimulation and non-stimulation groups.Venous blood samples were obtained from all participants,peripheral blood mononuclear cells were isolated from these samples and cultured with(stimulation groups)or without(non-stimulation groups)staphylococcal enterotoxin B(SEB)for 24 hours.Then,the mRNA expression of IL-31 on PBMCs was assessed via real-time reverse transcription-PCR.ELISA was used to detect the total serum IgE level in these objects.The severity of AD in patients was rated according to scoring atopic dermatitis(SCORAD).The relationship between the mRNA expression of IL-31 and the level of serum total IgE.severity of atopic dermatitis,and degree of pruritus.was evaluated.Results The expression of IL-31 mRNA on non-stimulated PBMCs from patients was 23.2 folds as high as that from the healthy controls(P＜0.01).The stimulation with SEB upregulated the mRNA expression of IL-31 on PBMCs.and the increase on PBMCs from patients was 20.44 times of that from the controls.The total serum IgE level was 260.05 IU/mL(5.9-1131.01 IU/mL)and 17.7 IU/mL(5-140.7 IU/mL)in the Patients and controls respectively(P＜0.01).There was no significant correlation between the mRNA expression of IL-31 and disease severity or total serum IgE level(r=0.07.0.22respectively.both P＞0.05)in patients witll AD.Condusions IL.3 1 is involved in t11e pathogenesis of AD,which is unlikely to be IgE-dependent.SEB can induce the rapid expression of IL-31 on PBMCs of healthy human,and is an important modulator for the production of IL-31.
