RESUMO
[Objective]To summarize the experience in treating malignant tumors based on the syndrome differentiation of the six meridians and the usage characteristics of classic formulas in the Treatise on Febrile and Miscellaneous Diseases.[Methods]Based on the analysis of the disease classification method of"six channels differentiation of syndromes"in Treatise on Febrile Diseases and Miscellaneous Diseases and the process of malignant tumor onset,advance and prognosis is dynamized and the possibility of traditional Chinese medicine in the prevention and treatment of malignant tumors by"preventing the disease before it changes"is explored.At the same time,the common clinical strategies for the treatment of malignant tumor adverse reactions are listed,the modern application of classic formulas in the treatment of malignant tumor according to the clinical characteristics of the disease and literature research is summarized.[Results]As a positioning method in the process of disease development,the differentiation of six meridians can indicate the depth of the disease and the state of the struggle between positive and evil Qi during the development of malignant tumors,providing theoretical reference for the formation mechanism,site of onset,and prognosis of malignant tumors.Classic formulas have the characteristics of clinical universality,standardization of addition and subtraction methods,and comprehensive participation in anti-tumor treatment,reflecting the potential advantages of traditional Chinese medicine in treating malignant tumors.Classical formulas have practical value in treating cancer fever,cancer pain,radiation inflammation,nerve damage,digestive tract reaction and so on.[Conclusion]The application of classic formulas can effectively improve the quality of life of patients with malignant tumors,with the characteristics of full process,overall,and flexibility.The role of classic formulas in the treatment of malignant tumors is worth further exploration.
RESUMO
【Objective】 To investigate the relationship between cerebrospinal fluid exosome-derived miR-630 and the function of brain microvascular endothelial cells （BMECs）. 【Methods】 The subarachnoid hemorrhage endothelial cell model was established to evaluate the effect of hemorrhagic cerebrospinal fluid （BCSF） on BMECs’ proliferation by MTT assay and cell cycle analysis. qRT-PCR and immunofluorescence staining were used to detect the expressions of endothelial cell tight junction protein （ZO-1） and adhesion molecule （ICAM-1 and VCAM-1）. Changes in NOx concentration were detected by radioimmunoassay. The cerebrospinal fluid exosomes in the experimental group （co-incubated with BCSF） and the control group （normal cerebrospinal fluid） were isolated and identified， and differences in the expressions of cerebrospinal fluid exosomal miR-630 between the two groups were compared. BMECs work changes after the intervention with miR-630 analogue were observed. 【Results】 The proliferation of BMECs was significantly inhibited in the experimental group； the mRNA and protein levels of ICAM-1， VCAM-1 and ZO-1 were significantly decreased， and the function of endothelial cells was significantly inhibited （P<0.05）. After the successful separation and identification of cerebrospinal fluid exosomes， the expression of miR-630 was significantly lower in the experimental group than in the control group （P<0.05）. The function of BMECs was significantly improved with miR-630 mimics. 【Conclusion】 The low expression of miR-630 in cerebrospinal fluid exosomes after subarachnoid hemorrhage is closely related to BMECs injury.
RESUMO
Objective To explore the therapeutic effect of subcutaneous negative pressure drainage and absorbable suture in preventing postoperative complications of cranioplasty.Methods The clinical data of 175 cases of skull defect admitted and treated in Department of Neurosurgeryof the Affiliated Hospital of Binzhou Medical University from January 2012 to February 2018 were retrospectively analyzed.According to the different intraoperative treatment methods,97 cases were treated with thread suture to the galea aponeurotica combined with general drainage (the general drainage group),and 78 cases were treated with absorbable suture to the galea aponeurotica combined with negative pressure drainage(the negative pressure drainage group).The galea aponeurotica were sutured intermittently with both silk thread and absorbable suture,and the drainage tube was placed outside the metal titanium plate under the skin,and removed after 48-72 hours.The postoperative complications of the two groups were compared.Results The incidence rates of subcutaneous hemorrhage,knotting reaction,infection of incision in the negative pressure drainage group were 1.3％ (1/78),0.0％ (0/78),and 0.0％ (0/78),respectively,which were significantly lower than those in the average drainage group [11.3％ (11/97),20.6％ (20/97),7.2％ (7/97)],the differences were statistically significant (x2 =6.85,18.16,4.13,all P ＜ 0.05).Conclusion The application of absorbable suture suturing galea aponeurotica and subcutaneous negative pressure drainage in skull repair can significantly reduce and prevent postoperative complications of cranioplasty.

RESUMO
Objective To investigate the mechanism of unbalanced expressions of endothelin receptors (ETA/ETB )in cerebral vasospasm (CVS)after subarachnoid hemorrhage (SAH).Methods The rat CVS models were established by injecting autologous blood into the cisterna magna the second time.Basilar artery morphology was observed under light microscope and immunofluorescence staining was conducted to dynamically detect ETA/ETB receptor expression.Results The cross-sectional area of the basilar artery in the SAH model group decreased at 2 d to 3 d,and then gradually returned to normal.ETA receptor expression in endothelial cells of the basilar artery increased at 2 d after SAH,peaked at 3 d and remained increased till 14 d.ETB receptor expression increased significantly in endothelial cells at 3 d,peaked at 7 d and remained the same level till 14 d.Conclusion The results suggest that ETA/ETB receptors play an important role in cerebral vasospasm after SAH.The specific expression differences of ETB receptor subtypes in the brain vascular layers need further study.
