In this paper we present a study on the microscopic identification of Dingkundan.For this purpose,a total of 29 constitutive Chinese medicines in Dingkundan were all detected and the characters of every constitutive Chinese medicine for microscopic identification were briefly described.We also provide the microscopic character pictures attached.

Objective This study is to explore the infratentoriat-supracerebellar keyhole approach for microsurgical treatment of pineal region tumors and to evaluate its curative efficacy and safety.Methods According to hi-fi quality MRI images,individual operation schemes were designed.Microsurgical infratentori- al-supracerebellar keyhole approach was used to resect lesions in 7 consecutive patients with prone postition.A 2.0 cm?2.5 cm surgical bone window was performed with its superior margin reaching to the inferior margin of the transverse sinus and confluence sinus.Results Among the 7 pineal region tumors,there were 2 ger- minomas,2 pineocytomas,1 pineoblastoma,1 glioma and 1 chlesteatoma.All cases were re-examined with MRI after operation and it was found that 6 lesions were totally removed and 1 was subtotally removed.The outcome of the treatment was satisfying.There was no infection,bleeding or death after surgery.The follow-up result in the near future was good.Conclusion The infratentorial-supracerebellar keyhole approach for the excision of pineal region tumors was proved to be a satisfactory means with a total removal rate,an excellent curative effect and small surgical trauma.

Objective: To investigate the effect of Scutellaria barbata D. Don on the expression of ADAM10 (a disintegrin and metalloproteinase 10) in primary liver cancer tissues in rats. Methods: Total of 120 Wistar rats were randomly divided into four groups: normal, model, matrine and Scutellaria barbata D. Don groups. The model of rat bearing primary liver cancer was induced by diethylnitrosamine. The rats in the matrine group and Scutellaria barbata D. Don group were fed with matrine and Scutellaria barbata D. Don powder, respectively. The rats in the normal group and model group were fed with 0.9% sodium chloride solution. The number of hepatocellular carcinoma nodules was calculated, and the tumor growth inhibition rate was also calculated. The pathologic changes of hepatic tissues in rats of each group were observed by hematoxylin and eosin staining. The expressions of ADAM10 in liver cancer tissues in these four groups were determined by immunohistochemistry and Western boltting. Results: The number of hepatocellular carcinoma nodules of the matrine group and Scutellaria barbata D. Don group was less than that of the model group (P < 0.05) with the appearance of apoptotic bodies. The tumor growth inhibition rate of Scutellaria barbata D. Don group was higher than that of the matrine group (P < 0.05). The positive expression rate and the expression level of ADAM10 in liver cancer tissues of the model group were significantly higher than those of the normal group (P < 0.05). The positive expression rate and the expression level of ADAM10 in liver cancer tissues of matrine group and Scutellaria barbata D. Don group were lower than those of the model group (P < 0.05). The positive expression rate and the expression level of ADAM10 in liver cancer tissues of Scutellaria barbata D. Don group were lower than those of matrine group (P < 0.05). Conclusion: Scutellaria barbata D. Don may inhibit the growth of primary liver cancer in rats through down-regulating the expression of ADAM10. Copyright © 2013 by TUMOR.

Objective To explore the changes of cytokines in myasthenia gravis children and the effect of glucocorticoid on the serum levels of them.Methods Forty cases of myasthenia gravis children were the observation group which was divided to group one (pre-glucocorticoid therapy)and group two (post-glucocorticoid therapy),and 20 cases of healthy children in the same period as the normal control group.The serum levels of cytokines INF-γ,TGF-β1,IL-10 and IL-18 of the observation group one and two and the normal control group were detected by ELISA and were compared between the observation group one and the normal control group and the observation group one and two.Results The serum levels of cytokine INF-γand IL-18 were higher and IL-10 and TGF-β1 were lower in the observation group than in the normal control group,the differences were statistically significant (t =4.45 ~16.72,P <0.01 ).Significant difference of INF-γ,TGF-β1 and IL-18 was found between the observation group one and two (t =8.12 ~10.68,P <0.01)and the sera level of IL-10 had no significant difference (P >0.05).Conclusions Cytokines INF-γ,TGF-β1,IL-10 and IL-18 are involved and probably play different roles in the pathogene-sis of myasthenia gravis in children;Glucocorticoid could affect the secretion of cytokines IFN-γ,TGF-β1 and IL-18 of myasthenia gravis children,which would ultimately to achieve the aim of interfering and con-trolling the clinical symptom of myasthenia gravis in children.

There are a lot of reports about the neuroprotection of mild hypothermia in the acute phase brain injury of aneurysmal subarachnoid hemorrhage. There are many mechanisms of brain damage involving in the development of brain damage in the acute phase of aneurysmal subarachnoid hemorrhage. Mild hypothermia can protect against various brain damages in the early stage of cerebral infarction. It may play a role in brain protection when it is used in the acute phase of aneurysmal subarachnoid hemorrhage.

The physical and chemical factors affecting the allergenic potency of the house bdust mite Dermatophagoides farinae extract were determined by skin test and ELISA technique in the asthmatic patients sensitive to the mite. The results showed that the allergenic potency of the extract could be reduced by heat sterilization, trypsin trea-tment and lyophization,but not lost completely,and that the potency could be increasedby supersonic treatment and repeated freeze-thaw(but less than 10 times).It was alsoshowed that the allergenic potency of the extract preserved at -20℃ was more stablethan those preserved at 4℃ or at room temperature,and that the mite extract preservedat 4℃ more than 9 years still had allergenic potency.
