Objective Transesophageal Doppler monitoring ( TDM) has been widely applied to fluid therapy in some major op-erations but rarely used in aortic valve replacement.The purpose of this study was to assess the value of TDM in fluid therapy, vasoactive drugs use, and left ventricular function in patients undergoing aorta valve replacement after cardiopulmonary bypass. Methods This study included 40 patients undergoing aotic valve replacement after cardiopulmonary bypass in Anhui Provincial Hospital from March 2014 to June 2015, which were randomly assigned to a TDM and a control group of equal number.TDM was used for the guidance of fluid infu-sion and vasoactive drug administration for the patients in the former group, while central venous pressure, mean arterial pressure, and heart rate were employed for those in the latter.The fluid volume infused, urine volume, blood loss, hemodynamics, arterial blood lac-tate, and outcomes were compared between the two groups. Results Compared with the control, the TDM group showed significantly increases in the colloidal fluid volume ([303 ±60] vs [373 ±65]mL, P<0.05), crystal fluid volume ([533 ±87] vs [596 ±83]mL, P<0.05), and urine volume ([274 ±95] vs [338 ±84]mL, P<0.05), but remarkable decreases in the red blood cell count, blood plasma vol-ume, postoperative extubation time, doses of dopamine and dobu-tamine, and length of hospital stay (all P<0.05).The hemodynamics were more stable and arterial blood lactate was lower in the TDM group than in the control (P<0.05). Conclusio n Transesophageal Doppler monitoring can timely and exactly manifest the hemodynamic changes and left ventricular function of the patient undergoing aotic valve replacement and provide precise guidance for fluid therapy and vasoactive drug administration.

The medical records of all 12 patients diagnosed as chronic active Epstein-Barr virus (CAEBV) infection at our hospital were analyzed retrospectively.There were 7 males and 5 females with a median onset age of 28 years.CAEBV was characterized by fever,splenomegaly,hepatomegaly and lymphadenopathy,etc.The abnormalities of laboratory examination included liver dysfunction,thrombocytopenia,anemia and leucopenia.EBV-DNA detected by real-time polymerase chain reaction was (1.7 × 103-3.5 × 107) copies/μg DNA in peripheral blood mononuclear cell.Among them,the outcomes were death (n =5),lost to follow-up (n =2) and T cell lymphoma (n =1).It is necessary to improve our awareness of CAEBV infection because of its poor prognosis and high mortality.

Objective To explore the applied value of thyroid imaging reporting and data system (TI-RADS) strati?fication in diagnosing thyroid nodules in patients with different ages.Methods A total of 527 patients with thyroid nod?ules (aged 26-65) were divided into four groups:aged 26-35 group, aged 36-45 group, aged 46-55 group and aged 56-65 group. TI-RADS was used to evaluate patients in four groups. The results of TI-RADS were compared with the pathologic di?agnostic analysis. Results For the low aged groups (aged 26-35 group and aged 36-45 group), the positive predictive val?ue, the negative predictive value and accuracy rate were more than 90%. With regard to the patients aged 46-55, the positive and negative predictive values and accuracy rate were 81.5%, 87.5%, and 81.9%, respectively. The positive and negative predictive values, accuracy rate were 76.6%,88.8%and 77.9%for patients aged 56-65 group. The diagnostic rate of TI-RADS in patients with thyroid lesions was lower in aged 56-65 group than that of other groups. Conclusion TI-RADS method is affected by age. The diagnostic rate is lower in the high age group than that of the low age group.

Objective To improve the diagnosis and treatment of Q fever endocarditis.Methods From 2008 to 2013,four cases of Q fever endocarditis were diagnosed in Peking Union Medical College Hospital.Clinical features,laboratory test,management and prognosis were analyzed with literature review.Result All four cases had long period of fever and heart murmur.Two patients represented with respiratory symptom and one with non-specific rash.General laboratory tests including complete blood cell count,ESR,C-reactive protein(CRP),liver function and radiology of lung did not show specific abnormalities.Signs of endocarditis were shown by ultrasound and important for diagnosis.Repeated blood culture was negative.All of the diagnoses were confirmed by serum antibody detection and the patients recovered well with treatment based on doxycycline or minocycline.Conclusions Endocarditis is the most common form of chronic Q fever,which is easily misdiagnosed because its blood culture is negative and may accompanied with varied manifestation such as pneumonia and liver injury.For the patients with chronic fever and blood culture negative endocarditis,chronic Q fever should be considered as differential diagnosis.The confirmatory method for diagnosis is serum antibody detection.Early and sufficient treatment may improve the prognosis.

Objective To explore the relationship of molecular biology characteristic and the treatment outcome,and influence factors of neoadjuvant chemotherapy (NAC) in inflammatory breast cancer (IBC).Methods The clinicopathological data of 103 IBC patients who were treated with NAC from January 2005 to June 2013 were analyzed retrospectively.Immunohistochemical method was used to detect the expression of estrogen receptor (ER),progesteron receptor (PR),human epidermal growth factor receptor 2 (HER-2) and E-cadherin.The treatment outcome were evaluated.Results In 103 IBC patients,ER negative was 48 patients,PR negative was 51 patients,HER-2 positive was 45 patients,E-cadherin positive was 66 patients.The effective rate of chemotherapy was 72.8％ (75/103).The effective rate of chemotherapy in taxane-based group was significantly higher than that in anthracycline-based group [80.6％ (50/62) vs.61.0％(25/41)],and there was significant difference (P ＜ 0.05).The effective rate of chemotherapy in ER,PR,E-cadherin negative patients was significantly higher than that in ER,PR,E-cadherin positive patients [83.3％ (40/48) vs.63.6％ (35/55),82.4％ (42/51) vs.63.5％ (33/52),83.8％ (31/37) vs.66.7％ (44/66)],and there was significant difference (P ＜ 0.05).The effective rate of chemotherapy in taxane-based group with E-cadherin positive patients was significantly higher than that in anthracycline-based group with E-cadherin positive patients [77.5％ (31/40) vs.50.0％ (13/26)] (P ＜0.05).No correlation existed between the expression of HER-2 and the treatment outcome of chemotherapy (P ＞ 0.05).Conclusion ER,PR and E-cadherin negative patients with IBC is chemosensitive to NAC.The positive expression of E-cadherin may be an important factor of chemotherapy resistance.For the patients with E-cadherin positive,taxane-based chemotherapy regimen can achieve a better effective rate.

Objective To investigate the effects of early Xuebijing injection on procalcitonin (PCT) with septic shock patients.Methods Sixty-five patients with septic shock were randomly divided into the control group and Xuebijing injection group.The patients in Xuebijing injection group were received Xuebijing injection therapy(50 ml Xuebijing + 100 ml 0.9％ NaCl injection,2 times/d,for 7 d) besides basic treatment,while in the control group were received basic treatment including antibiotic susceptibility + early fluid resuscitation + correct acidosis.At the entering the ICU day and 1,3,5 d after treatment,patients were collected 5 ml venous blood serum C reactive protein(CRP) and PCT,and before treatment and at the 5th,7th day after treatment conducted APACHE Ⅱ evaluation to observation of curative effect of two groups.Results Before treatment,there were no significant difference in terms of heart rate,blood pressure,PCT,CRP,APACHE Ⅱ scores between the two groups (P ＞ 0.05).There was no significant difference in terms of PCT and CRP between the two groups at the 1 d after treatment(P ＞0.05).While at the 3th day after treatment,PCT and CRP of Xuebijing group were lower than of control group and the differences were significant ((7.37 ± 2.58) μg/L vs.(12.25 ± 3.32) μg/L,(64.32 ± 11.12) mg/L vs.(72.37 ± 12.42) mg/L;P ＜0.05).The APACHEⅡ score in control group at before and 5th,7th day after treatment were (20.48 ± 4.41),(16.52 ± 3.45),(12.78 ± 2.91) respectively,in Xuebijing injection group were (20.74 ± 4.73),(12.48 ± 2.76),(9.24 ± 6.67) respectively.And all indices were significant different time points between groups (P ＜ 0.05).At 7th day after treatment,15 cases were improved,10 cases progressed and 8 cases died in the control group and the effect rate was 75.8％ (25/33).Meanwhile,22 cases were improved,5 cases progressed and 5 cases died in the Xuebijing group and effect rate was 84.8％ (27/32).There was significant difference between two group(x2 =7.27,P =0.03).Conclusion Early Xuebijing injection application can inhibit the PCT r~tion of septic shock patients and improve the prognosis.

Objective To explore the effects of Shenfu injection combined with low-dose hydrocortisone on plasma lev?els of human leukocyte antigen (HLA)-DR and procalcitonin (PCT) in patients with septic multiple organ dysfunction syn?drome. Methods A total of 118 patients with septic multiple organ dysfunction syndrome were divided into three groups:control group (n=39), experimental group 1 (n=39) and experimental group 2 (n=40). The control group received conventioanl medicine therapy, while the experimental group 1 received Shenfu injection (100 mL, 2/d, for 7 d) combined with conventio?anl medicine therapy, and the experimental group 2 received Shenfu injection combined with low-dose hydrocortisone (200 mg/d, for 14 d) besides conventional medicine therapy. The peripheral blood samples were collected for the detection of HLA-DR, PCT and lipoperoxide (LPO) before treatment, 1 d, 3 d amd 7 d after treatment. The mortality in 14 d was record?ed. Results The mortality rates in 14 d were 61.5%(24/39), 41.0%(16/39) and 25.0%(10/40) for control group, experimen?tal group 1 and experimental group 2 (χ2=8.15, P<0.05). There were no significant differences in PCT, HLA-DR and LPO levels before treatment and 1 d after treatment between the three groups (P>0.05). The plasma levels of PCT and LPO were significantly decreased in control group, experimental group 1 and experimental group 2 after 3-d and 7-d treatment, but the levels of HLA-DR was significantly increased (P < 0.05). Conclusion The combination therapy of Shenfu injection and low-dose hydrocortisone can effectively reduce PCT level and increase HLA-DR level, which promotes the improve?ment of patients with septic multiple organ dysfunction syndrome.

Objective To explore the efficiency of temporary cardiac pacing on the acute poisoning patients with serious bradycardia.Methods Thirty-eight cases of the acute poisoning patients with serious bradycardia were treated randomly with temporary cardiac pacing (pacing group, 18 cases) and drug therapy (control group,20 cases) and followed with treatment for poisoning. Results Right ventricular pacing were successfully performed in 18 cases and the temporary cardiac pacemaker were placed. With the further treatment of poisoning, in the pacing group, the efficiency of anit-bradycardia and the poisoning cure rate was 100% and 88. 9% , respectively, whereas being 60% and 65.0% in the control group, respectively. The efficiency of anit-bradycardia and the poisoning cure rate were significantly different between the two groups (P < 0.01 or P < 0.05 ). Conclusions The treatment of temporary cardiac pacing has effect on the acute poisoning patients with serious bradycardi. It can effectively improve the rate of patients' resuscitation.
