Objective To approach the effects of decoction changed from Didangtang and Xiaoxianxiongtang Modified Formula on mucoprotein in stratum medium and the III-type collagen level of serum in experimental rats with fibrosis disease in lung interstitial tissue. Methods 40 male Wistar rats were randomly divided into 4 groups, that is pseudo-operation group, model control group, traditional Chinese drug group (TCD) and western medicine group (WM). Every group has 10 rats. Acid hydroc bleocin was dripped disposably into trachea of every group rats except pseudo-operation group, and Sodium Chloride with same volume as Acid hydroc bleocin was dripped disposably into trachea of pseudo-operation group. 24 hours after operation, the rats of TCD was lavaged with Decoction changed from Didangtang and Xiaoxianxiongtang Modified Formula, and the rats of WM was lavaged with Prednisone physiological saline solution. The rats of pseudo-operation group and model control group was lavaged with Sodium Chloride of same volume as TCD and WM. 28 days after operation, the rats was executed. And contents of mucoprotein in stratum medium of and the III-type collagen serum was detected. Results Didangtang and Xiaoxianxiongtang Modified Formula could decrease contents of mucoprotein in stratum medium of and the III-type collagen in serum of experimental rats, and extenuate fibro-accrementition in lung interstitial tissue. Conclusion Didangtang and Xiaoxianxiongtang Modified Formula has the function of treating fibrosis disease in lung interstitial tissue probably by decreasing contents of extracellular matrix in experimental rats with fibrosis disease in lung interstitial tissue.

Objective To explore the mechanism of nanometer calcium combined with tonifying kidney herbs on osteoporosis by studying the expression of CaBP-D9K mRNA and protein in the intestinal mucosa of osteoporosis rats due to kidney deficiency. Method The rat model of osteoporosis due to kidney deficiency was established by ovariectomy. Applying the nanometer calcium and nanometer calcium combined with tonifying kidney herbs (big, middle and small dosage) to the rats for 12 weeks, choosing Gushukang, E2 and Gai’erqiD600 as the control drugs. The expression of the CaBP-D9K mRNA and protein in the intestinal mucosa of the osteoporosis rats due to kidney deficiency was determined by the method of RT-PCR and western blotting. Result There was CaBP-D9K and protein expression in the normal rats intestinal mucosa tissue, which plays an important role in the process of the intestinal calcium absorption. The episode of the rat osteoporosis due to kidney deficiency is related to the change of the CaBP-D9K and protein expression and has influence on the intestinal calcium absorption. Conclusion The nanometer calcium combined with tonifying kidney Chinese herbs can stimulate the calcium absorption of intestine, prevent and treat the osteoporosis due to kidney deficiency through regulating the expression of CaBP-D9K mRNA and protein in the intestinal mucosa.

Objective To observe the effects of Purpura decoction and its disassembled prescriptions on peripheral blood reticulated platelets (RP) and serum thrombopoietin (TPO) of idiopathic thrombocytopenic purpura (ITP) model mice, to explore the action mechanism and core structure of the prescription. Methods Totally 84 BalB/c mice were randomly divided into normal group, model group, prednisone group, Purpura decoction group, Buyi Qixue group, Buqi Huoxue group and Buxue Huoxue group. ITP mouse model was made by injecting intraperitoneally guinea pig-antimouse platelet serum. From the 5th day of modeling, mice were intragastrically administered. The normal group and model group were fed with normal saline 0.2 mL per mouse. Purpura decoction group was fed with Purpura decoction 0.43 mL per mouse. Buyi Qixue group was fed with Buyi Qixue decoction 0.36 mL per mouse. Buqi Huoxue group was fed with Buqi Huoxue decoction 0.27 mL per mouse. Buxue Huoxue group was fed with Buxue Huoxue decoction 0.3 mL per mouse. Prednisone group was fed with prednisone acetate suspension 0.2 mL per mouse. Ten days later, took the blood from the eyeball and isolated serum, the mouse peripheral platelet, RP and TPO were observed. Results After treatment, the platelet count of treatment groups was improved. Compared with before treatment, Purpura decoction group,Buqi Huoxue group and prednisone group had significant difference in platelet count (P<0.05). The RP of model group was significantly higher than the normal group (P<0.05), but RP absolute value was lower than the normal group (P<0.05). Compared with the model group, RP of treatment groups reduced (P<0.05), and RP was negatively correlated with platelet count (P<0.05). TPO level of the model group was higher than that of the normal group (P<0.01). TPO of treatment groups declined significantly, and had significant differences with that of the model group (P<0.05). Conclusion Core structure of Purpura decoction is qi tonifying and blood activating drug. The mechanism of treating ITP is related with lowering RP and TPO.

This study was aimed to observe four kinds of kidney-tonification medicine, which were Epimedium, pso-ralen, Ligustrum lucidum, Polygonum with the active ingredient of icariin, psoralen, oleanolic acid, stilbene glucoside and their orthogonal compatibility. There were two kinds of non-kidney tonification medicine, which were Chuanx-iong and astragalus with the active ingredient of TMP and astragaloside. The observation was made on the regulatory role of rat bone marrow stem cells (BMSCs). A total of 65 SD rats were randomly divided into the normal control group, positive transformed control group, kidney-tonification compatibility group (including Group 1, Group 2, Group 3, Group 4, Group 5, Group 6, Group 7, Group 8, and Group 9), non-kidney tonification medicine control group (in-cluding TMP group and astragaloside group). Intragastric administration of medication was given to the kidney-tonifi-cation compatibility group and the non-kidney tonification medicine control group, once a day for 3 consecutive days. Intragastric administration of equal amount of normal saline was given to the normal control group and the posi-tive transformed control group. On the third day of intragastric administration, rats in each group were sacrificed. Serum containing medication was used in the culture of BMSCs for 6, 12, or 18 days. ELISA method was used to quantitatively detect the expression activity and content of BMP2 on the 6th, 12th, or 18th day, in order to evaluate the degree of bone cell differentiation degree. Real-time quantitative PCR method was used for detection of expression of Bmp2, Smad1, Smad4 mRNA in serum containing medication in the culture of BMSCs on the 18th day. The results showed that the kidney-tonification compatibility can improve the expression activity and content of BMP2 culture in vitro, with the peak on the 12th day. The kidney-tonification compatibility groups can upregulate expressions of Bmp2, Smad1, Smad4 mRNA. It was concluded that the active ingredient compatibility of kidney-tonification medicine can promote BMSCs. Its mechanism may be related to the upregulation of expression of Bmp2, Smad1, Smad4 mRNA, and the activity and content of Bmp2.

Objective To observe the effects of nourishing-kidney herbs on rat model with glucocorticoid-induced osteoporosis.Methods 60 Wistar rats male and female half and half were randomly divided into a normal group,a model group and a nourishing-kidney group.By intramuscular injection of dexamethasone (2.5 mg/kg) twice a week to replicate osteoporosis rat model.All groups were treated for 9 weeks.Detected the BMD of femur in vitro and determined the bone metabolism marker in serum by biochemical process.Results The BMD decreased obviously (0.109± 0.007)g/cm2 and the content of TRAP in serum increased evidently (9.96± 1.15) μg/ml in the model group.In the nourishing-kidney group,the BMD was up-regulated (0.116 ± 0.007)g/cm2,and TRAP down-regulated(5.76 ± 0.85)μg/ml.Conclusion Intramuscular injection of dexamethasone can induce GIO rat model,and nourishing-kidney herbs have the effect of anti-osteoporosis.

ObjectiveTo analyze the clinicopathologic features of hereditary cutaneomucosal venous malformation (VMCM) in a Chinese family.MethodsFamily history was investigated in a family with VMCM,and tissue specimens were obtained from the lesions of the proband and subjected to histopathological analysis.ResultsAmong 65 members from 5 generations of the family,19 were affected by VMCM,hinting an autosomal dominant inheritance.None of the family members experienced gastrointestinal bleeding,central nervous system disorders,or cardiac defects.Affected individuals usually presented with multiple irregularly sized,blue-violet,elevated and slightly indurated masses located in the oral mucosa and subcutaneous tissue of the extremities.Pathological analysis showed malformed veins with abnormally dilated cavities and irregularly thickened walls.Although small veins were abnormally proliferating and clustered,there was no endothelial discontinuity.The smooth muscle layer was thickned in a varying degree or absent.ConclusionA diagnosis of VMCM is made according to the inheritance manner,clinical manifestation and pathological findings.

ObjectiveTo investigate the change of mood and cognitive function of patients with liver cirrhosis before and after liver transplantation (LT).MethodsA total of 26 patients with liver cirrhosis before LT and 24 patients after LT admitted in the Third Afifliated Hospital of Sun Yat-sen University from September 2012 to September 2013 were included in this prospective study. Moreover, 26 healthy controls were also included in normal control group. The informed consents of all participants were obtained and the local ethical committee approval had been received. The 26 patients before LT were assigned in preoperative group, among them, 23 were males and 3 were females with the average age of (50±9) years old. The 24 patients after LT were assigned in postoperative group, among them, 22 were males and 2 were females with the average age of (50±6) years old. Among the healthy controls, 23 were males and 3 were females with the average age of (49±9) years old. Clinical data of the three groups were collected respectively. The mood status and the cognitive function of the participants were assessed with Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Scale (HAMA), Number Connection Test A (NCT-A) , Digit Symbol Test (DST). The results of multiple groups were compared with one-way analysis of variance and pairwise comparisons were conducted with LSD-t test.ResultsThe HAMD, HAMA scores, NCT-A results and DST scores of the preoperative group were (16.2±3.5), (17±5), (56±13) s and (36±11) and those of the postoperative group were (14.2±3.7), (16±3), (52±12) s and (42±7) and those of the normal control group were (7.3±2.4), (8±3), (38±8) s and (54±9). Compared with the normal control group, the HAMD, HAMA scores and NCT-A results of the preoperative group increased significantly (LSD-t=11.919, 8.596, 6.883;P<0.05) and the DST scores decreased significantly (LSD-t=-6.972,P<0.05). Compared with the normal control group, the HAMD, HAMA scores and NCT-A results of the postoperative group increased significantly (LSD-t=8.591, 9.942, 5.475;P<0.05) and the DST scores decreased significantly (LSD-t=-5.599,P<0.05). Compared with preoperative group, the HAMD scores of the postoperative group decreased significantly (LSD-t=-2.209,P<0.05) and the DST scores increased significantly (LSD-t=1.243,P<0.05).ConclusionsPatients with liver cirrhosis have obvious depression, anxiety and cognitive disorder before LT. A month after LT, depression and cognitive disorder improve obviously, but cannot recover to the normal level. The anxiety improvement is not obvious.
