Objective To explore the function of stereotactic radiation therapy (SRT) and wholebrain radiation therapy (WBRT) in treatment of multiple brain metastasis tumor.Methods Fifty-two patients with multiple brain metastasis tumor were retrospectively analyzed.The patients were divided into simple stereotactic radiation therapy group (22 cases) and whole-brain radiation therapy + stereotactic radiation therapy group (30 cases) according to the radiation therapy method.The median overall survival time and distant brain tumor recurrence rate in 1 year etc.were compared between 2 groups.Results There were no statistical differences in the median overall survival time and fatality rate between simple stereotactic radiation therapy group and whole-brain radiation therapy + stereotactic radiation therapy group:13.0 months (95％ CI 8.05-27.84) vs.13.4 months (95％ CI 8.57-19.48),86.36％ (19/22) vs.86.67％ (26/30),P＞ 0.05.The distant brain tumor recurrence rate in 1 year in simple stereotactic radiation therapy group was significantly higher than that in whole-brain radiation therapy + stereotactic radiation therapy group:45.45％ (10/22) vs.20.00％ (6/30),and there was statistical difference (x2 =3,861,P =0.049).Conclusion Stereotactic radiation therapy and whole-brain radiotherapy can achieved similar median overall survival time.

Objective To explore the clinical characteristics,changes of neuroendocrine hormone before and aftter operation in patients with craniopharyngioma,so as to provide the basis for the replacement therapy after operation and educational practice.Methods The clinical data of 183 patients with craniopharyngioma were retrospectively analyzed. Results (1)Symptoms mainly were headache with nausea,disevesight,the second symptom was polydipsia and polyuria,in child,growth and development retardation was more,and another was hypothalamus syndrome.(2)Functions in endocrine:functions in thyreoid,adrenal and gonad(except PRL),the dysfunctions in neurohypophysis was displayed with completed insipidus and immaturity insipidus,contrasted it anteoperation to that postoperation,it was obvious in statishcs meanings (P＜0.05). Conclusions In patients with craniopharyngioma,children and adolescent is more than the other people,clinical situation is complicated,neuroendocrine hormone is derangement before and after operation,tumor itself to oppress and operation trauma are the basic reasons for the hypofunction of neuroendocrine hormpne,hormones replacement therapy and monitoring should be catch earlier.

Objective To research the expressions of Sirtuin 1 (SIRT1) in colorectal cancer and normal tissue and the relationship with clinicopathologic features.Methods The expression levels of SIRT1 mRNA and protein were detected respectively by quantitative real-time reverse transcriptase PCR (RT-QPCR) and immunohistochemistry (IHC) in 45 cases of colorectal carcinoma and 30 cases of normal mucous membrane tissue,and the relationships between the expression status and clinicopathologic features were analyzed.Results In colorectal carcinoma,the expression of SIRT1 mRNA were higher than that in control group [M(QR):2.488(3.447) vs.1.563(2.867),Z =-2.304,P ＜0.05],so was the protein level (71.1％ vs.43.3％,x2 =5.787,P =0.029).The expression of SIRTI was associated with lymph node metastasis (RT-QPCR:Z =-2.160,P =0.031;IHC:P =0.043),neoplasm stages (RT-QPCR:Z =-2.411,P =0.016;IHC:P =0.008),and might associated with the tissue differentiation (RT-QPCR:x2 =10.864,P =0.004;IHC:P =0.322).On the other hand,no significant differences were observed regarding age,sex,tumor size,gross type,depth of invasion,tumor site and distant metastasis.Conclusion The expression of SIRT1 in colorectal cancer is higher than that in control group,the high level of SIRT1 is related to the tumorigenesis and progression of colorectal cancer as well as correlated with prognosis in colorectal cancer.

Objective To compare the effect of occupy effects of tumor in situ before surgery(OETS) and after neurosurgery (ANS) on neuroendocrine dysfunction and grading of neuroendocrine function in children with craniopharyngioma. Methods The grading evaluation criteria of neuroendocrine dysfunction in children with craniopharyngioma were drew up according to references and the endocrine feedback principle. Based on these grading evaluation criteria, the clinical date of 227 cases of children with craniopharyngioma who underwent neurosurgical treatment were retrospectively studied. These children were divided into pre-pubertal group (167 cases) and pubertal group (60 cases). The neuroendocrine impairment status before and after the surgery were evaluated separately. Results Among 227 children with craniopharyngioma, after the surgery, the incidence of the hypothalamus-pituitary-thyroid dysfunction increased from 16.74%(38/227) to 67.40%(153/227), the incidence of the hypothalamus-pituitary-adrenal gland dysfunction increased from 14.54%(33/227) to 44.49%(101/227), and the the incidence of pituitary function impairment increased from 17.62%(40/227) to 21.15%(48/227). Meanwhile, the incidence of body temperature dysregulation, sleeping disorder, personality abnormality and cognitive abnormality all increased after the surgery. The scoring and grading on neuroendocrine dysfunction in pre-pubertal group were increased after the surgery (Z=-5.20, P<0.01; Z=-4.94, P<0.01,). The scoring and grading on neuroendocrine dysfunction in pubertal group were increased after the surgery( Z=-4.10, P<0.01;Z=-4.25, P<0.01). Conclusions Both the mass effect of tumor in situ of craniopharyngioma and the neurosurgical treatment can be harmful to the neuroendocrine function. Even though the surgery can remove the mass effect of tumor in situ in the saddle area, it can increase the level of grading of neuroendocrine dysfunction. The status of neuroendocrine dysfunction can be evaluated by the grading evaluation criteria of neuroendocrine dysfunction in children with craniopharyngioma, which then provides an effective evaluation tool for the reconstruction and rehabilitation of neuroendocrine function.

The mollusicidal effect and toxicity to fish with META-Li in field were tested in mountain areas in Zhejiang Province. The snail control test, which had 3 groups including a META-Li group, niclosamide group and control group, were performed by the spraying method. The adjusted mortalities of snails in the META-Li group on the 3rd, 7th and 15th day were 89.76% , 87.98% and 94.10% , respectively, in the niclosamide group were 89.70% , 83.22% and 94.72% , respectively .and there was no significant difference between the two groups ( P > 0.05), but they were decreased obviously compared with the control group, which were 9.24% , 9.50% and 15.21% , respectively(P <0.05). The toxicity test to fish with META-Li included 3 groups, namely a high concentration META-Li group, low concentration META-Li group and control group, and none fish was dead. It is suggested META-Li has low toxicity to fish, and is suitable to snail control in aquiculture areas.

OBJECTIVE: To determine the effect of lung protection mechanical ventilation on respiratory function in the elderly undergoing spinal fusion. METHODS: Sixty 70-85 year old patients, ASA class II or III, undergoing spinal fusion were randomly assigned into 2 groups (30 in each group): a protection mechanical ventilation group (group P) and a conventional mechanical ventilation group (group C). Low VT and low level positive end expiratory pressure (PEEP) mechanical ventilation were applied in group P (VT=6mL/kg, RR=12-18 b/min, I:E=1:2, PEEP=10 cmH2O, alveolar recruitment performed once every 15 min), while traditional ventilation was used in group C ( VT=10-12 mL/kg, RR=12 b/min, I:E=1:2). Arterial blood samples were taken and pH, PaO2, PaCO2, PaO2/FiO2, A-aDO2, HR, SBP, DBP and CVP were recorded before the operation (T0), 1 h after tracheal intubation (T1), tracheal extubation immediately (T2), 1 h after tracheal extubation (T3), 1 d, 2 d, and 3 d after the operation (T4, T5, and T6). The pulmonary complication was also examined 1 d after the operation. RESULTS: At T1, T2, T3, T4 and T5, PaO2 and PaO2/FiO2 in group P were higher than those in group C, but A-aDO2 in group P was lower than that in group C. Five patients had bronchitis, 5 had hyoxemia, and 3 had atelectasis in group C, but 2 bronchitis in group P. The incidence of pulmonary complication was 43.3% in group C and 6.6% in group P. There was no significant difference in HR, SBP, DBP and CVP between the 2 groups. CONCLUSION Lung protection mechanical ventilation improves the arterial oxygenation and accelerates the recovery of respiratory functions in elderly patients after spinal fusion operation, with no influence on hemodynamics.

Objective:To preliminarily investigate dermoscopic characteristics of trichoblastoma, and to provide ideas for clinical diagnosis of trichoblastoma.Methods:Clinical data were collected from 5 patients with trichoblastoma who underwent both dermoscopic and histopathological examinations in Wuhan No.1 Hospital from November 2018 to July 2021, and dermoscopic features were analyzed retrospectively.Results:According to the presence or absence of pigments, trichoblastoma was divided into 2 subtypes: pigmented trichoblastoma (3 cases) and non-pigmented trichoblastoma (2 cases) . Dermoscopic examination of the 3 cases of pigmented trichoblastoma showed blue-gray ovoid nests (3 cases) , arborizing vessels (2 cases) , blue-gray globules (2 cases) , bright white structureless areas (2 cases) , concentric structures (1 case) and ulcers (1 case) ; no yellow-whitish homogenous structure was found. As for non-pigmented trichoblastoma, dermoscopic features included arborizing vessels (2 cases) , yellow-whitish homogenous structures (2 cases) , bright white structureless areas (2 cases) and blue-gray globules (1 case) ; no ulcers or blue-gray ovoid nests were observed in either case.Conclusion:Dermoscopic patterns differ between pigmented and non-pigmented trichoblastoma, so dermoscopy can provide preliminary diagnostic clues for trichoblastoma.

Laparoscopic pancreaticoduodenectomy is an important surgical undertaking, mostly used for benign and malignant tumors in the pancreatic head and periampullary region. The postoperative pancreatic fistula is the main factor to cause death after pancreaticoduodenectomy, and pancreaticojejunostomy is an independent risk factor for pancreatic fistula. In order to reduce the incidence of pancreatic fistula, surgeons have proposed dozens of pancreaticojejunostomy, but so far there are no randomized trials proved which method of pancreaticojejunostomy is better than the others. This article reviews the methods and characteristics of different pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.
