ObjectiveTo explore the effects of hemofiltration on serum enzyme (SE),endotoxin (ET) and malonaldehyde (MDA) of dogs with heat stroke caused shock.MethodsSixteen healthy male hybrid dogs were randomly divided into 2 groups,8 for each:as heat stroke group (HS group ) and hemofiltration group (HF group).Severe heat stroke model was induced with high temperature.The dogs were taken out of the heating cabin when it reached heat stroke level,and then observed under normal temperature without treatment.The dogs in HF group was immediately treated with hemofiltration.The changes of SE,ET,MDA of two groups of dogs were observed and the survival time between two groups was compared,ResultsThe time from heat exposure to shock was ( 107.00 ± 28.52 ) and ( 111.38 ± 22.24 )minutes in HS group and HF group respectively ( t =- 0.354,P =0.729 ).The SE ( CK,LDH,ALT,AST) of the dogs were all higher after heat stroke,and the dogs of two groups showed no siginificant difference (P > 0.05).At three hours after heat stroke,the SE increased apparently in HS group and HF group,but the level was significantly lower in HF group. Before heat stroke,the serum ET showed no siginificant difference between two groups ( P > 0.05 ).After heat stroke,the serm ET was much higher than before ( P <0.01 ),but there was still no siginificant difference between two groups ( P >0.05 ).At three hours after heat stroke,the ET increased both in HF group and HS group,but the level was lower in HF group.Before heat stroke,the serm MDA had no siginificant difference between two groups ( P > 0.05 ).After heat stroke,the serm MDA was much higher than before ( P < 0.0l ),but there was still no siginificant difference between two groups (P > 0.05 ).After heat stroke in three hours,the MDA of HS group rose apparently while HF group slowly declined.The median survival time of HF group was 180 min while HS group was 75 min,the survival rate showed siginificant difference (P < 0.01 ).Conc4usions HF can improve the prognosis of dogs with heat stroke caused shock,prolong its survival time,reduce mortality.The mechanism is probably that HF clear serum MDA,partially clear serum ET and then eventually reduce cell and tissue injury and reduce SE.

Objective To retrospectively investigate the impact of postoperative radiotherapy ( RT) on the relationship between molecular subtype and survival in patients with breast cancer ( BC ) . Methods A total of 716 women who were admitted to our hospital in 2008 and newly received unilateral mastectomy were divided into Luminal A ( LA ) , Luminal B?HER?2?negative ( LB1 ) , Luminal B?HER?2?positive ( LB2) , HER?2 overexpression ( HER?2+) , triple?negative ( TN) , and unassigned subtypes according to the 2011 St. Gallen Consensus. The Cox model was used to analyze the differences in overall survival ( OS) and disease?free survival ( DFS ) rates between subtypes in all patients, RT group, or non?RT group. The Kaplan?Meier method was used to calculate OS and DFS rates. The Cox model was used to perform the factor analysis. Results In all patients, the median follow?up time was 71?4 months;the overall mortality rate was 10?5%;the incidence of treatment failure ( death+relapse+metastasis) was 14?9%;217 patients ( 30?3%) received RT. The multivariate analysis showed that there was no significant difference in OS between subtypes in any group ( all P>0?05 ) . In all patients, patients with LB1 subtype or unassigned subtype had significantly poorer DFS rates than those with LA subtype ( HR= 1?881, P= 0?035;HR= 1?907, P=0?049) . In the non?RT group, patients with LB1 subtype had significantly poorer DFS rates than those with LA subtype (HR=3?324, P=0?01). In the RT group, there was no significant difference in DFS rate between subtypes ( all P>0?05) . The two?dimensional cross analyses of RT and subtype demonstrated that patients with LB1 subtype in the non?RT group had lower OS and DFS rates than patients with LA subtype in the RT group ( P=0?09,0?06) . Conclusions Patients with LB1 subtype have lower OS and DFS rates than patients with LA subtype, especially in the non?RT patients. RT has no impact on the relationship between subtype and prognosis.

Objective To investigate the clinical significance of the gray head B ultrasound quantitative determination on early detection for preterm low birth weight infants with cerebral white matter damage. Methods From 2013 January to August 2014 in the NICU department of our hospital, 100 cases of preterm and low birth weight infants were ran-domly divided into the treatment group and the control group. After birth 72 hours, the value of cerebral white matter was measured by head B ultrasound combined with medical image analysis software. The cases, whose early values of cerebral white matter were above 130, were treated with early brain nerve nutrition and rehabilitation. The develop-ment of nerve growth was followed up in 3 months and 6 months after birth, respectively. Results The NBNA score of premature and low birth weight infants was significantly higher than that of the control group. By the follow-up investi-gation in 3 months and 6 months after birth, the nerve growth of the treatment group was significantly better than that of the control group. Conclusion The head B ultrasound gray-scale quantitative analysis has important guiding signifi-cance for early diagnosis of premature and low birth weight infants with cerebral white matter injury,and it can help to judge the prognosis and guide early clinical treatment.

Objective:To analyze the prognosis and influencing factors of patients with brain metastases from non-small cell lung cancer (NSCLC) treated with different doses of whole brain radiotherapy (WBRT).Methods:A total of 244 NSCLC patients with brain metastases who underwent WBRT in the Fourth Hospital of Hebei Medical University from 2013 to 2015 were analyzed retrospectively. According to different doses of WBRT (EQD 2Gy), they were divided into the 30-39 Gy group ( n= 104) and ≥40 Gy group ( n= 140). The intracranial progression-free survival (iPFS) and overall survival (OS) were compared betweentwo groups. According to the number of brain metastases, GPA score, KPS score, chemotherapy and targeted therapy, the prognosis of different doses of WBRT was further analyzed. Results:The median iPFS and OS of all patients were 6.9 months and 11.8 months, respectively. Univariate survival analysis: the 1-year iPFS and 1-year OS between two groups were 22.5% and 25.4%( P=0.430) and 41.1% and 46.4%( P=0.068), respectively. Multivariate survival analysis: different doses of WBRT were not associated with the improvement of iPFS and OS; independent factors influencing iPFS included local boost, gender, number of brain metastases, chemotherapy and targeted therapy; independent factors influencing OS included gender, number of brain metastases, chemotherapy and targeted therapy. Subgroup analysis: in patients with KPS≥90, the 1-year iPFS and OS of patients with WBRT ≥ 40 Gy were seemingly better than those of their counterparts with 30-39 Gy, but the difference was statistically significant only in OS ( P=0.047), the difference was not statistically significant in iPFS ( P=0.068); in patients with chemotherapy, the 1-year iPFS and OS of patients with WBRT≥40 Gy were better than those of their counterparts with 30-39 Gy ( P=0.017, P=0.012); in patients with targeted therapy, the 1-year iPFS and OS in the WBRT≥40 Gy group were better than those in the 30-39 Gy group ( P=0.012, P=0.045). Conclusions:The 30-39 Gy may be the appropriate dose of WBRT for NSCLC patients with brain metastases. WBRT≥40 Gy does not bring more benefits. WBRT≥40 Gy may benefit NSCLC patients with brain metastases with high KPS score or active systemic therapy.

Objective:To analyze the prognosis and influencing factors of different radiotherapy modes in patients with brain metastases from non-small cell lung cancer (NSCLC), and to explore the best benefit population with radiotherapy boost under different prognostic scores.Methods:634 patients with brain metastasis from NSCLC admitted to the Fourth Hospital of Hebei Medical University from 2013 to 2015 were analyzed retrospectively. According to different radiotherapy modes, they were divided into three groups: no radiotherapy group ( n=330), whole-brain radiotherapy group (WBRT)( n=127) and whole-brain radiotherapy combined with boost group (WBRT+ boost)( n=177). The intracranial progression-free survival (iPFS) and overall survival (OS) were calculated by Kaplan-Meier method. The multivariate prognostic factors were analyzed by the Cox models. Results:The median iPFS and OS of all patients were 6.9 months and 9.0 months, respectively. In the no radiotherapy, WBRT and WBRT+ boost groups, the 1-year iPFS was 15.1%, 16.3% and 40.2%( P=0.002), and the 1-year OS was 33.7%, 38.2% and 48.1%( P<0.001), respectively. Multivariate survival analysis demonstrated that different radiotherapy modes were the independent factors affecting iPFS and OS. Subgroup analysis revealed that for patients with 1-3 brain metastases, the 1-year OS and iPFS in the WBRT+ boost group were better than those of WBRT alone ( P=0.026, P=0.044) when GPA score was 2.5-4.0; the 1-year OS and iPFSin the WBRT+ boost group were better than those of WBRT alone ( P=0.036, P=0.049) when there was no targeted therapy; for patients with ≥4 brain metastases, the 1-year iPFS in the WBRT+ boost group was better than that of WBRT alone ( P=0.019, P=0.012) when GPA score was 2.5-4.0 and there was no targeted therapy. When the GPA score was 0-2 or there was targeted therapy, the 1-year OS and iPFS in the WBRT+ boost group were better than those of WBRT alone, but the difference was not statistically significant (all P>0.05). Conclusions:Radiotherapy can significantly improve the iPFS and OS of NSCLC patients with brain metastases. When the number of brain metastases is 1-3, GPA score is 2.5-4.0 or no targeted therapy, boost may improve the iPFS and OS; when the number of brain metastases is more than 4, GPA score is 2.5-4.0 or no targeted therapy, boost may only bring iPFS benefit; when GPA score is 0-2 or targeted therapy, boost may not benefit significantly.

Malfunction of the ventral subiculum (vSub), the main subregion controlling the output connections from the hippocampus, is associated with major depressive disorder (MDD). Although the vSub receives cholinergic innervation from the medial septum and diagonal band of Broca (MSDB), whether and how the MSDB-to-vSub cholinergic circuit is involved in MDD is elusive. Here, we found that chronic unpredictable mild stress (CUMS) induced depression-like behaviors with hyperactivation of vSub neurons, measured by c-fos staining and whole-cell patch-clamp recording. By retrograde and anterograde tracing, we confirmed the dense MSDB cholinergic innervation of the vSub. In addition, transient restraint stress in CUMS increased the level of ACh in the vSub. Furthermore, chemogenetic stimulation of this MSDB-vSub innervation in ChAT-Cre mice induced hyperactivation of vSub pyramidal neurons along with depression-like behaviors; and local infusion of atropine, a muscarinic receptor antagonist, into the vSub attenuated the depression-like behaviors induced by chemogenetic stimulation of this pathway and CUMS. Together, these findings suggest that activating the MSDB-vSub cholinergic pathway induces hyperactivation of vSub pyramidal neurons and depression-like behaviors, revealing a novel circuit underlying vSub pyramidal neuronal hyperactivation and its associated depression.
