RESUMO
Gastric cancer is one of the most common malignant tumors, which seriously threatens people's life and health with high morbidity and mortality. Operation-centered comprehensive therapy is the most vital method for treating gastric cancer.With the development of surgical concepts, science and technology, as well as the development of a large number of high-standard clinical studies, the treatment of gastric cancer has made great progress, and the surgical method has gradually changed from open surgery to minimally invasive surgery.The research focus of early gastric cancer is to protect function and reduce trauma.Consensus has also been reached on the scope of lymph node dissection for locally advanced gastric cancer, and minimally invasive surgical methods have achieved certain results in terms of safety and effectiveness.For advanced gastric cancer with only one incurable factor, aggressive surgical treatment can also achieve good results.In recent years, high-definition laparoscopy, 3D laparoscopy, fluorescent laparoscopy, surgical robots and artificial intelligence have all promoted the development of gastric cancer diagnosis and treatment technology.This paper reviews the current surgical treatment of gastric cancer in order to better guide clinical treatment and benefit patients.
RESUMO
OBJECTIVE：To investigate the effects of dexmedetomidine on regional cerebral oxygen saturation and cerebral function in patients undergoing intracranial aneurysm embolization. METHODS ：Totally 44 patients undergoing intracranial aneurysm embolization in the First Affiliated Hospital of Hunan University of TCM during Jun. 2017-Aug. 2019 were collected and randomly divided into group D （22 cases）and group C （22 cases）. Ten minutes before anesthesia induction ，group D was given intravenous injection of Dexmedetomidine hydrochloride injection 1 μg/kg；group C was given buffered normal saline 20 μL. Both groups were induced with Propofol emulsion injection+Midazolam injection+Fentanyl citrate injection+Cisatracurium besylate for injection. During the operation ，group D was given Dexmedetomidine hydrochloride injection 0.5 μg（/ kg·h）+Fentanyl citrate injection+Benzsulfosum atracurium for injection+Propofol emulsion injection to maintain anesthesia ；group C was continuously pumped with buffered normal saline 0.5 μg（/ kg·h）+Fentanyl citrate injection + Benzsulfosum aratracurium for injection Propofol emulsion injection to maintain anesthesia. Before anesthesia induction （T0）， immediately after anesthesia。induction （T1）， 1 min after tracheal intubation （T2）， immediately after operation finished （T3），immediately afte extubation（T4），the mean arterial pressure（MAP），heart rate 中国药房 2021年第32卷第7期 China Pharmacy 2021Vol. 32 No. 7 ·865· （HR），regional cerebral oxygen satur ation（rSO2）were observed in 2 groups. The levels of neuron specific enolase （NSE）and S100 β protein in serum were measured at T1，T3，6 h after operation （T6）. The recovery time ，intraoperative blood loss ， nitroglycerin amount and the occurrence of ADR were recorded. RESULTS ：MAP and HR of group D at T 2-T4 were significantly lower than those at T 0；MAP and HR of group C at T 2-T4 were significantly higher than those at T 0；the group D were significantly lower than the group C at the same period （P＜0.05）；there was no statistical significance in rSO 2 between 2 groups at T 0-T4（P＞ 0.05）. The levels of serum NSE and S 100β protein in 2 groups at T 3 were significantly higher than at T 1；those in 2 groups at T 6 were significantly lower than at T 3，but those of group D were significantly lower than the group C at T 3（P＜0.05）；there was no statistical significance in the levels of serum NSE or S 100β protein between 2 groups at T 1（P＞0.05）. The recovery time of anesthesia，the amount of nitroglycerin ，the incidence of tachycardia ，nausea and vomiting ，restlessness，shivering and cough in group D were significantly shorter or lower than group C （P＜0.05）；there was no statistical significance in the intraoperative blood loss between 2 groups（P＞0.05）. CONCLUSIONS ：Dexmedetomidine can maintain the hemodynamic stability of patients with intracranial aneurysm embolization during the perioperative period ，has little effect on rSO 2 and brain function ，and has good safety.
RESUMO
Objective Through clinical observation and statistics, to get the best curative effect of surgical operation in treating pigment nevus method and provide clinical guidance. Methods We reviewed of face and neck patients (1100 patients) with pigmented nevus in the department in the department of the dermatology,plastic surgery from January 2013 to October 2015, two different methods was designed on each parts and effect of the treatment, especially satisfaction degree was analyzed by statistical methods.Results In 100 cases of patients, only 20 patients had mild scar hyperplasia at the neck incision and the rest of the patients were satisfactory. For special parts such as mouth,nose and eye around,along thedirection of the muscle, arc and along the direction of dermatoglyph incision was designed respectively, patients obtained with higher postoperative satisfaction (P<0.05) . Conclusion In pigmented nevus of face and neck surgery treatment, surgical incision design requires dynamic and static combining method,incision design is important for the postoperative effect and patients' satisfaction.
RESUMO
This article began from the characteristic and research method of the syndrome in Traditional Chinese Medicine(TCM)and proteomics,analyzed the superiority and the feasibility of introduction of proteomics into the study of syndrome essence.The author thought that proteome and syndrome in TCM were amazing similar in the aspects of integrity,developments,space and complexity,there was maybe some kind of inner link and the corresponding relations between them.Therefore, the proteomics had the special superiority when it was compared with the general microscopic parameter in study of syndrome essence,also even more accord with the characteristics of syndrome in itself.This article also generalized the research achievement of syndromic proteomics in TCM in recent years from the aspects of specification,thought and method,the relativity of concrete syndrome type and proteome.This article demonstrated the magnificent prospect of proteomics in the study of the syndrome essence of the TCM.
