OBJECTIVE: To establish quality standards of Liuwei gancao pills. METHODS: TLC method was adopted for qualitative identification of Glycyrrhiza uralensis in prescription. The content of liquiritoside was detected by HPLC. RESULTS: TLC spot was separated well and clear; the linear range of liquiritoside was 4.024 0～24.144 0 ?g?mL-1(r=0.999 7) with an average recovery of 98.3%(RSD=0.96%,n=6); the content of G. uralensis in each pill was not less than 2.8 mg by the content of liquiritoside. CONCLUSION: Established quality standards can be used for the quality control of Liuwei gancao pills.

Objective To investigate the variation of coagulation parameters in type 2 diabetes mellitus(T2DM)patients with microvascular complication. Methods Coagulation and fibrinolysis parameters were measured in 40 healthy controls (control group) and 80 T2DM patients (T2DM group) with (47 patients) and without (33 patients) microvasular complications. Results Compared with those in control group, the serum levels of fibrinogenand D-D dimmersin in T2DM group were found to be increased significantly:(4.29±1.70) mg/L vs. (3.12±0.49) mg/L, 0.395 (0.265-0.910) mg/L vs. 0.215 (0.163-0.300) mg/L, P<0.05;while the activity of antithrombin III and protein S levels were significantly decreased in T2DM group:(94.11±25.04)%vs. (103.90±12.48)%,(70.23±23.22)%vs. (90.35±17.35)%, P<0.05. Amongst the T2DM patients, the serum levels of APTT, fibrinogen,D-D dimmers, and the activity of protein S in patients with microvascular complication were found to be significantly higher than those in patients without microvascular complication:(38.09±5.73) s vs. (34.53±4.13) s,(4.60±1.93) mg/L vs.(3.86±1.21) mg/L, 0.630(0.320-1.200) mg/L vs 0.310(0.240-0.405) mg/L, (79.4± 22.16)%vs. (57.15±18.05)%, P<0.05. Conclusion Hypercoagulable state and decreased anti-coagulation ability may contribute to the risk of development of microvascular complication in T2DM patients.

Objective To investigate value of peripheral NLR and PLR for the survival of patients with primary gastric cancer.Methods The clinical data of 132 primary gastric cancer patients and 30 healthy controls were analyzed by the Kaplan-Meier, Log-rank test and multivariate COX regression.Results NLR, PLR levels of the case group were significantly higher than that in the healthy control group (t=6.67, P=0.000;t=13.23, P=0.000); the higher the age, the greater tumor diameter, the higher the degree of differentiation, lymph node metastasis, and not be treated with surgery, NLR and PLR could increase (P<0.05);NLR and PLR showed a significant positive correlation (r=0.3164, P=0.0002);survival time of low NLR group was (57.59 ±2.23) months and high NLR group was (35.22 ±3.09) months(P<0.05);survival time of low PLR group was (54.09 ±2.66) months and high PLR group was (35.22 ±2.75 ) months(P<0.05);age, clinical stage, lymph node metastasis and NLR, PLR levels were independent factors for the overall survival in patients with gastric cancer ( P<0.05 ) .Conclusion NLR and PLR of gastric cancer patients increase significantly and are closely related to tumor size, metastasis, clinical stage, and the deterioration, which showes some predictive value for the survival prognosis of the patients.

OBJECTIVE:To study the judgment method of allergens in TCM decoction.METHODS:Judgment methods and thinking of suspected drugs in TCM decoction were summarized by analyzing clinical case and the literatures.RESULTS:The allergens in the TCM decoction can be found out using prescription analysis and patch test.Bioresonance system also can be applied to detect and analyze allergens in TCM decoction.CONCLUSION:TCM decoction can cause allergic reaction,and the allergens can be identified by comprehensive methods.

Objective To observe the effects of cystamine, a tissue transglutaminase (tTG) inhibitor, on the development of rat liver fibrosis induced by carbon tetrachloride. Methods One hundred male SD rats were randomly divided into control group (n=20), hepatic fibrosis group (n=40) and cystamine group (n=40) . Liver fibrosis model was induced by intraperitoneal injection of carbon tetrachloride. Cystamine (112 mg·kg-1·d-1) was administered by intraperitoneal injection 2 days before injection of carbon tetrachloride. The rats were sacrificed at weeks 4 and 8, and the liver tissues and serum specimens were obtained. The mRNA expression of tTG, smooth muscle-alpha (α-SMA), collagen-Ⅰ and tissue inhibitors of metalloproteinase-1 (TIMP-1) were detected by real time PCR. The protein expression of tTG and α-SMA, liver function and content of hydroxyproline in liver tissues were determined by Western blot. Histological changes of the liver was observed under microscope. The fibrosis conditions of rat liver in each group were evaluated according to the semi-quantita-tive scoring system. All the data were analyzed by one-way ANOVA. Results Eight weeks after the injection of carbon tetrachloride, obvious injury of the liver in liver fibrosis group was observed. The levels of alanine trans-aminase (ALT), total bile acid, total bilirubin, hydroxyproline, tTG, α-SMA, collagen-Ⅰ and TIMP-1 were (1313±157)U/L, (99.9±18.5)μmol/L, (10.9±1.6)μmoL/L, (55±12)μg/g, 145.6±51.2, 130.3±44.6, 211.3±75.1 and 162.4±53.5. After administration of cystamine, the levels of ALT, total bile acid, total bilirubin, hydroxyproline, tTG, α-SMA, collagen-Ⅰ and TIMP-1 were (378±87) U/L, (61.0±12.7) μmol/L, (9.8±1.7) μmol/L, (70±14 ) μg/g, 48.6±12.3, 40.7±12.3, 63.9±16.0, 59.2μ23.4. Conclusion Cystamine can alleviate the carbon tetrachloride-induced rat liver fibrosis by inhibiting the tTG pathway.

Objective To investigate the anti-fibrosis effect of a 5-lipoxygenase (5-LO)specific inhibitor AA-861 on liver fibrosis. Methods Liver fibrosis was induced in male Sprague Dawley rats by intraperitoneal injection of carbon tetrachloride(CCI4).AA-861(0.2 mg/100 g/d)was administrated by intraperitoneal injection starting 2 days before the first dosage of CCI4 and rats were killed at weeks 2,4,and 6.Liver specimens were obtained from each animal and fixed with 4%formaldehyde for histological analysis. The Mrna expression of 5-LO,smooth muscle-alpha(α-SMA),Collagen-1,matrix metalloproteinase-2(MMP-2)and tissue inhibitors of metalloproteinase-1(TIMP-1),the protein expression of 5-LO were evaluated by real time PCR and Western blot respectively. Histological analysis was performed by microscopy observation. Fibrosis conditions in rat liver in each group were evaluated according to the semi-quantitative scoring system (SSS), Hyp in rat livers and the hepatic functional biochemistry were also detected. Results Along with the aggravation of liver fibrosis, the gene expression of 5-Lo,α-SMA,Collagen-1,MMP-2 and TIMP-1 increased gradually, and the level of ALT, TBA, Hyp and SSS score also increased gradually. With the administration of AA-861,the Mrna expression of 5-LO,α-SMA,Collagen-1,MMP-2,TIMP-1 and the protein expression of 5-LO decreased remarkably, and the reduction in TIMP-1 Mrna expression was more significant than that in MMP-2.Six weeks after AA-861 treatment, the level of ALT, TBA, Hyp and SSS score were also decreased significantly. Conclusion AA-861 ameliorates CCI4 induced rat liver fibrosis by inhibiting the 5-LO pathway and decreasing the expression of 5-LO,α-SMA,Collagen-1,MMP-2 and TIMP-1.

The hair cycle is effected by various components in the microenvironment of hair follicle niche. The dermal adipocytes, as an important part, has been shown to be relevant to epidermal homoeostasis during hair follicle regeneration, and the periodic change of hair also affects the dermal adipocytes. This article reviewed the relationship between dermal adipocytes and hair follicle, and tried to find a new sight in the field of hair regenerations.
