Objective To explore the clinical effect of early mechanical ventilation coupled with mild hypothermia in the treatment of severe traumatic brain injury(STBI)and its effect on serum C -reactive protein (CRP)and hemorheology.Methods According to the order of admission,110 patients with STBI were divided into two groups.55 cases in the control group were given conventional symptomatic treatment and early mechanical ventilation, while 55 patients in the observation group were given early mechanical ventilation coupled with mild hypothermia.The clinical efficacy was compared between the two groups.Results The good prognosis rate was 74.55% in the observation group,which was significantly higher than 56.36% of the control group (χ2 =7.65,P <0.05).The serum CRP in the observation group admitted to hospital 2,3,5,7d were significantly decreased compared with the control group(t =7.48,8.04,7.34,7.82,all P <0.05).After treatment,the hear whole blood viscosity was (6.03 ±0.89)mPa·s, low shear whole blood viscosity was (3.18 ±0.19)mPa·s,plasma viscosity was (1.21 ±0.18)mPa·s,hematocrit was (37.56 ±3.23)%,and those were decreased compared with before treatment(t =8.45,7.54,7.04,8.02,all P <0.05).And there were significant differences compared with the control group(t =7.77,6.69,6.44,7.49,all P <0.05).Conclusion The effect of early mechanical ventilation coupled with mild hypothermia in the treatment of STBI has good effect,and it can reduce serum CRP levels,improve blood rheology,which is conducive to patients'prognosis.

Objective To explore the clinical curative effect of hyperbaric oxygen therapy for severe cranio-cerebral injury,and its influence on the level of serum interleukin -1 beta(IL -1 )and interleukin -6(IL -6). Methods 150 patients with severe craniocerebral injury were selected and divided into two groups by random and single blind method.75 patients of the control group were treated with conventional therapy,75 patients of the observation group were given hyperbaric oxygen on the basis of the conventional treatment,and the clinical efficacy was compared between the two groups.Results The total effective rate of the observation group was 94.67%,which was significantly higher than 77.33% of the control group,the difference was statistically significant(χ2 =7.83,P <0.05).There were no significant differences in GCS and ADL scores between the two groups(t =1.22,2.39,all P >0.05).After treat-ment,the GCS and ADL scores of the observation group were (12.18 ±2.13)points,(67.46 ±12.55)points,which were significantly higher than those before treatment(t =8.01,7.76,all P <0.05),and there were significant differ-ences between the two groups(t =7.23,6.82,all P <0.05).Before treatment,there were no significant differences in the serum levels of IL -6 and IL -1 between the two groups(t =2.10,1.01,all P >0.05).After treatment,the serum levels of IL -1 and IL -6 in the observation group were (127.48 ±16.35)pg/mL,(89.66 ±13.47)pg/mL, which were significantly lower than before treatment(t =8.34,7.89,all P <0.05),there were significant differences between the two groups(t =7.65,7.22,all P <0.05).Conclusion Implementation of hyperbaric oxygen in patients with severe traumatic brain injury on the basis of conventional symptomatic treatment can effectively improve the clinical symptoms and signs,reduce the serum IL -1 and IL -6 levels,promote the recovery of brain function and ability of daily life,and which is worth to be promoted in clinical.

Background and purpose: The position of thymidine kinase 1 (TK1) expression during cell division is in the cytoplasm. It is a catalytic enzyme to convert deoxythymidine into thymidylate. It is the key enzyme of pyrimidine salvage pathway. The aim of this study was to analyze the serum expression level of TK1 in patients with breast cancer, and explore the application of serum TK1 test in clinical assessments of diagnosis, treatment and prognosis for breast cancer. Methods: Patient data were collected from the patients admitted in Comprehensive Breast Health Center at Rui Jin Hospital. Chemiluminesence dot blot assay was used to detect serum TK1 levels in 145 breast cancer patients and 55 patients with breast ifbroadenoma. The correlations of serum TK1 levels with breast tumor biological behavior was further studied. Results:Serum TK1 expression levels was signiifcantly increased in breast cancer patients [(2.749±0.122)pmol/L] when compared to breast fibroadenoma patients[(1.319±0.126)pmol/L, P<0.000 1]. Serum TK1 levels were statistically increased in patients with lymph node metastasis (P=0.049), distal metastasis (P=0.003 1), and late TNM stages (P=0.01). No serum TK1 level differences were found in patients with different ages (P>0.05), different tumor grades (P=0.453) and different tumor size (P=0.908). Preoperative imaging results including breast ultrasound, breast mammography and breast magnetic resonance were analyzed by assessments of BI-RADS category, and serum TK1 levels in patients with different BI-RADS categories were studied. Serum TK1 levels in patients with breast ultrasound BI-RADS categories 4C-6 were signiifcantly higher than those with category 0-4B (P<0.001). Consistently, the serum TK1 levels in patients with MR BI-RADS categories 4C-6 were higher than categories 0-4B (P=0.005). The serum TK1 levels in patients with mammography BI-RADS categories 4C-6 were higher than categories 0-4B (P=0.032). The serum TK1 levels were signiifcantly increased in patients with ER high expression in breast tumor tissues than those with low expression (P=0.034). Serum TK1 levels had no differences in patients with different expression levels of PR, HER-2 and MIB-1 (P>0.05). Most patients were followed up in our outpatient department for about 2 years. No progression-free survival differences were found in 2years. Conclusion:Serum TK1 test might be a potential tool for screening, prognosis determination and effect evaluations of targeted therapy in breast carcinoma.

Objective:To investigate the calcium-phosphate metabolic condition in maintenance hemodialysis patients with chronic kidney disease (CKD), and to observe the effect of large dose calcitriol on secondary hyperparathyroidism (SHPT).
Methods:We tested and compared the serum levels of calcium, phosphate, intact parathyroid hormone (iPTH), and alkaline phosphatase (AKP) in hemodialysis patients at different hemodialysis time (Group A with hemodialysis period≤3 years and Group B with hemodialysis period>3 years). We also detected those indexes before and after treating SHPT with large dose calcitriol. Twenty SHPT patients were divided into Group I (enlargement of parathyroid gland or nodule detected by color Doppler ultrasound) and Group II (normal parathyroid gland detected by color Doppler ultrasound).
Results:In the maintenance hemodialysis patients, the serum phosphate was (2.11±0.38) mmol/L and iPTH was (581.11±487.75) pg/mL. The serum level of iPTH in Group B was higher than that in Group A [(828.13±690.39) pg/mL vs (477.94±324.73) pg/mL, P<0.001]. In Group I, the serum level of iPTH [before vs after:(2471.7±898.3) pg/mL vs (2510.4±825.7) pg/mL] and AKP [before vs after:(524.2±18.8)U/L vs (511.3±19.3)U/L] did not change after the treatment of large dose calcitriol (P>0.05). In Group II, the serum level of iPTH [before vs after:(1358.5±302.8) pg/mL vs (369.3±43.4) pg/mL, P<0.001] and AKP [before vs after:(565.9±23.9)U/L vs (234.8±21.1)U/L, P<0.001] decreased signiifcantly after the treatment of large dose calcitriol.
Conclusion:Patients with longer time of hemodialysis have a higher level of iPTH. Large dose calcitriol can improve the clinical syndrome of SHPT, and decrease the level of iPTH and AKP in SHPT patients with normal parathyroid gland.

Objective To discuss MRI characteristics of dysplastic gangliocytoma of the cerebellum.Methods MRI manifesta-tions of 13 cases with dysplastic gangliocytoma of the cerebellum verified by operation and pathology were analyzed retrospectively. Results All of 13 cases were located in the cerebellar hemisphere and vermis.The lesions presented striated pattern of iso-intensity signal and hypo-intensity signal on T1-weighted images.The sign of tiger stripes was the feature in dysplastic gangliocytoma on T2-weighted and FLAIR images.All of the tumors showed slightly striated enhancement after intravenous administration of contrast agent.The mass effects of dysplastic gangliocytoma of the cerebellum along with the forth ventricle and brain stem oppressed were seen in all cases.NAA was mildly reduced on magnetic resonance spectroscopy (MRS)in 7 cases of dysplastic gangliocytoma of the cerebellum.Conclusion There are distinctive manifestations in MRI images for dysplastic gangliocytoma of the cerebellum,which has crucial diagnostic value before operation.
