Objective To analysis the clinical feaures and risk factors of recurrent intracerebral hemorrhage(ICH). Methods Analysis clinical data of 68 recurrent ICH patients and compared with those of patients with first-ever ICH. Results 43 recurrences were seen in 38 patients.The mean interval between 2 episodes was(3.9?2.8)years.The most common type of recurrence was"ganglionic-ganglionic",next was"ganglionic-thalamic",and"ganglionic-lo- bar"seldom.Most recurrences occurred contrala-terally and seldom at the same site as the first episode.In contrast to those with first-ever ICH,patients with recurrent ICH most have a hypertension and course of longer,all with a poor control.Analysis showed that the hypertension course was positively and the age of the first hemorrhage was negatively associated with the recurrence of ICH.Conclusion The risk of recurrence of ICH is relatively high within the first 4 years after the previous hemorrhage.Positively control hypertension to normal level,It will have impartant meaning to prevent occurrence of recurrent ICH.

Objective To develop a rapid and sensitive method for the determination of bisphenol A in drinking water by liquid chromatography-electrospray tandem mass spectrometry. Methods Bisphenol A was extracted from the drinking water sample by a SEP-PAK C18 column,eluted with methanol and concentrated with a rotary evaporator. The extract was analyzed by liquid chromatography-tandem mass spectrometry with electrospray ionization. Results The calibration curve of bisphenol A was linear in the range of 5 -100 ng/ml,the linear equation was y =6 796.61x -8 655.64 and the correlation coefficients of linear calibration curve was 0.999 2. The limit of detection (S/N=3) and the limit of quantification (S/N=10) of bisphenol A were 0.007 5 ng/ml and 0.025 ng/ml,respectively. The rates of recovery of bisphenol A were from 83.46% to 94.00% and the relative standard deviation was 3.06% -4.60%. Conclusion The method is simple,rapid,accurate and is applicable to the qualitative and quantitative determination of bisphenol A in drinking water.

Objective To observe the effects of early exercise on the expression of synaptophysin pro-tein and Nissl bodies in the hippocampus after hypoxic-ischemic brain damage( HIBD) , and to investigate possi-ble mechanisms. Methods A total of 35 neonatal Wistar rats aged 7 days were randomly divided into a train-ing group of 13, a control group of 11 and a sham-operation group of 11. HIBD was induced in the rats of the training and control groups, while those in the sham-operation group had the left common carotid artery separa-ted, but without ligation. Seven days after successful modeling, the training group began swimming training for 10 min every day lasting for 14 days, while the other groups were not trained. Western blotting was used to detect the expression of synaptophysin in the affected hippocampus of the brain based on the ratio of the gray band val-ues for synaptophysin and beta. Nissl staining was applied to observe the number of Nissl bodies and the morphol-ogy of the neurons in the hippocampus. Results The average expression of synaptophysin in the sinistrocere-bral hippocampus of the rats in the control group was significantly lower than that in the sham-operation group, but significantly higher than that of the training group. The control group had significantly fewer Nissl bodies than the sham-operation group, but significantly more than the training group. Conclusion Early training can in-crease the expression of synaptophysin and the number of Nissl body in the hippocampus after hypoxic-ischemic brain damage.

Objective To explore the risk factors influencing the prognosis of patients with acute poisoning by analysis of clinical data of 356 patients in order to provide the scientific evidence for planning therapeutic strategies in ICU.Methods The clinical data of 356 patients with acute poisoning were collected during the period from January 1,2005 through December 30,2009,and the clinical findings from close observation were filled into the tables of specially designed “ Clinical observation of acute poisoning patients”.Some risk factors of 356 cases with complete clinical data were studied by single-factor analysis and Logistic multiple regression,such as gender,age,mode and cause of poisoning,kind of poison agents,time elapsed from poisoning to admission into the hospital,time elapsed from poisoning to admission into ICU,length of hospital stay,cardiopulmonary resuscitation,mechanical ventilation,APACHE Ⅱ score.Results Three hundred fifty-six patients with complete data were divided into survival group (n =260) and death group (n =96).Univariate analysis showed the length of hospital stay (5.72 ± 4.37) d,APACHE Ⅱ score (10.27 ±7.77),time elapsed from poisoning to admission into ICU (17.16 ± 31.22)h in the survival group,and the length of hospital stay (3.53 ± 5.79) d,APACHE Ⅱ score (18.78 ±8.66),time elapsed from poisoning to admission into the ICU (37.21 ±67.35) h in the death group (P ＜0.05 or P ＜ 0.01).The differences in rates of CPR,mechanical ventilation and kind of poison agents between the two groups were statistically significant (P ＜ 0.05).Multivariate Logistic regression analysis revealed that the length of hospital stay,APACHE Ⅱ score,rates of cardiopulmonary resuscitation,mechanical ventilation and kind of poison agents were positively correlated with prognosis of patients with acute poisoning (P ＜ 0.05).Model to predict mortality was established:Y =-0.817-0.137X1 +0.140X3 + 2.133X4 + 1.039X5-0.291X6.Conclusions Hospital stay,APACHE Ⅱ score,cardiopulmonary resuscitation,mechanical ventilation and kind of poison agents were independent risk factors for predicting prognosis.APACHE Ⅱ score system and Logistic regression analysis can be used to evaluate the severity and prognosis of patients with acute poisoning.

ObjectiveTo explore the clinical characteristics and radiological manifestations of immune reconstitution inflammatory syndrome(IRIS)in acquired immunodeficiency syndrome(AIDS)patients with tuberculosis(TB)during highly active antiretroviral therapy(HAART).MethodsThe clinical and radiological data in 4 AIDS patients with TB who presented IRIS were analyzed retrospectively.ResultsThe clinical presentations of IRIS in 4 patients included fever(4 cases),weakness and weight loss(3 cases),abdominal pain(2 cases),cough with sputum(1 case),dyspnea(1 case).Cervical and(or)supra-clavicular lymph node enlargement were seen in 3 patients,inguinal lymph node enlargement in 1 patient,abdominal lymph node enlargement in 1 patient,hilar or mediastinal lymph node enlargement in 2 patients,pulmonary parenchyma and liver were involved in 2 patients,the involvement of kidney,adrenal gland,mesentery,peritoneum,psoas,brain and cutis was respectively found in 1 patient.The clinical and radiological presentations of IRIS were temporary and self-limited,improvement can be seen with antituberculosis therapy and HAART. ConclusionsIt is possible to have IRIS during HAART in AIDS patients with TB.Imaging examinations play an important role in the early diagnosis,monitoting and evaluating the response to therapy of IRIS.

Objective Tocheck and evaluate on clinical practice teaching files for providing a foundation of improved clinical teaching levels with enhanced establishment of practice teaching files. Methods The practice teaching files of eighteen clinical departments in a military medical university were selected as the subject and were evenly divided into teaching plans and teaching records as well as teach-ing summary three parts and 15 items. Each item had 2 scores in which quantity had one score and quality has another one. Evaluation results were converted into 100 points system. Results Among practice teach-ing files of eighteen clinical departments, 4 scored more than 90, 8 scored between 80 to 89, 3 scored between 70 to 79, 3 scored between 60 to 69. Three advanced departments are obstetrics and gynecology, auxiliary department and emergency department. There were no significant differences in the scores of major surgery and internal medicine. Compared with that of other departments in the hospital, the specialty of hospital had low scores. It showed that most of the clinical practice of the file information was relatively sound with complete records and some departments had missing items or incomplete and non-standard doc-umentation records. Conclusion Qualitative study on practice teaching files can reflect clinical practice teaching quality. And it is meaningful for us to enhance teaching files construction and to improve clinical practice teaching levels.

Objective To investigate the effect of recipient's pre-transplant triglyceride (TG) abnormalities on early graft function (EGF) after kidney transplantation.Methods According to the inclusion and exclusion criteria,154 identified living-kidney transplant recipients in the 309 Hospital of Chinese PLA from Jan.2011 to Dec.2014 were enrolled in present study,including 124 males and 30 females,and aged of 31.9 ± 8.4 years.The cohort was divided into two groups:TG normal group (0.40＜TG≤1.70mmol/L,n=107) and TG abnormalities group (TG＞l.70mmol/L or require lipid lowering therapy,n=47).The incidences of poor early graft renal function (PEGF),slow graft function (SGF) and delayed graft function (DGF) were compared between the two groups,and then the serum creatinine (Scr) levels were compared among the patients showing immediate graft function (IGF) at 3rd,7th and 30th day after transplantation.The ROC curve was drawn up taking TG as diagnosis index to explore the optimal cut-offvalue for predicting PEGF,SGF and DGF after transplantation.Results Compared with the TG normal group,the TG abnormalities group showed significantly higher incidence of PEGF and DGF (P＜0.05).Among the IGF patients,the TG abnormalities group showed higher Scr level at the 7th and 30th day after transplantation (P＜0.05).The area under ROC curve (AUC) reflected TG levels for PEGF,SGF and DGF were 0.774,0.704 and 0.818,respectively (P＜0.05).The optimal cut-offvalues were all 1.37mmol/L.Conclusions Recipients with abnormal pre-transplant TG level may have worse EGF after renal transplantation.The risk of developing PEGF,S GF and D GF tends to emerge when pre-transplant TG level is higher than 1.37mmol/L.

Objective To investigate whether the donor's glomerular filtration rate (GFR) to recipient's weight ratio (Dg/Rw) is a useful tool to predict early clinical outcome in living-related do-nor transplantation.Methods A total number of 108 living donor transplant recipients in the Chinese Military 309th Hospital from Jan.2014 to July 2015 were enrolled in this study.The patients who had multi-organ transplantation or developed grafts rejection,delayed graft function,hydronephrosis or renal vascular stenosis were excluded.The 90 qualified recipients were divided into G1 group (Dg/Rw ≤0.81),G2 group (Dg/Rw 0.81～1.11),and G3 group (Dg/Rw≥1.12).We respectively analyzed the relationship between recipient's serum creatinine Scr and Dg/Rw at 3-,7-,30-day and 1 year after transplantation.Results Scr at 3-,7-,30-day and 1 year after transplantation had linear correlation with Dg/Rw.As compared with G1 and G2 groups,Scr level was significantly reduced in G3 group at different time points (P＜0.05).Conclusion Dg/Rw has a negative relationship with Scr level after renal transplantation.Pre-transplant Dg/Rw is a potential index to predict the early clinical outcome in living-related donor transplantation.

Objective To investigate the correlation between de nove anti-endothelial cell antibodies (AECA) and adverse events after renal transplantation and the effect of transplanted renal function within six months after operation.Methods The expression of AECA in serum of 85 renal transplant recipients was detected by indirect immunofluorescence assay (ⅡF) before and 1 day,3 days,7 days,15 days and 1 month after renal transplantation.The patients were divided into double positive group (AECA positive before and after surgery),single positive group (postoperative de nove AECA positive) and negative group (preoperative and postoperative AECA negative) according to AECA test results.The occurrence of adverse events in each group such as DGF,rejection,infection and so on,as well as the serum creatinine levels were recorded at each time point within six months.Results Of the 85 recipients,29 were positive for AECA,including 19 in the double positive group,10 in the single positive group,and 56 in the negative group.The incidence of rejection in single positive group (30％) was higher than that in the rest two groups (5.3％ for double positive group,and 17.9％ for negative group),but there was no statistically significant difference (P =0.21).The incidence of DGF in the single positive group,double positive group and negative group was 70.0％,26.3 ％ and 32.1 ％ respectively.The positive rate of the single positive group was significantly higher than that of the rest two groups (P =0.04),and the duration of DGF was significantly longer in the single positive group than that of the rest two groups (P＜0.01).The incidence of infection in the single positive group,double positive group and negative group was 20.0％,21.1％ and 8.9％respectively,and there was no significant difference among the three groups (P =0.31).As compared with the double positive group and the negative group,the serum creatinine level was significantly increased in the single positive group at 1st week,1st month,3rd month and 6th month after operation (P =0.02,P =0.04,P =0.04 and P =0.02 respectively).Conclusion Postoperative AECA can increase the risk of DGF,prolong the duration of DGF,and affect the recovery of renal function within 6 months after renal transplantation.
