Objective To observe the efficacy of invasive ventilation (Ⅳ) in treatment of acute pulmonary edema (APE), and to explore the factors associated with prognosis. Method From March 2005 to December 2007, 23 APE patients, who were hospitalized in the EICU of People' s Hospital of Peking University and the con-ventional treatment and noninvasive ventilation were not effective, were treated by Ⅳ (PEEP 5~18 cmH2O). Blood pressure, heart rate, respiratory rate, and arterial blood gas values were recorded accurately before and after ventilation and compared with each other. Regression analysis was used to analyze the factors associated with prog-nosis. Resets Three hours after Ⅳ, the blood pressure, heart rate, respiratory rate, arterial blood gas were sig-nificanfly improved (P <0.01). Among the 23 patients, 11 survived, and the other 12 patients died. Nine pa-tients died of MOF. Among 16 patients with cardiac function Ⅲ-Ⅳ, 10 died. Among 15 patients with acute my-ocardial infarction, 9 died. Among 11 patients with renal insufficiency, 9 died. The multivariate logistic regression analysis showed that the reduced left ventricular ejection fraction, the lower mean arterial pressure, and the in-creased creatinine were the independent predictor of prognosis. Conclusions Invasive ventilation is an effective method of treating patients with acute pulmonary edema. Proper ventilation may improve the cardiac function and clinical symptoms, but it's not the fundamental measure for increasing cure rate. 1he renal insufficiency and heart failure are the independent predictor of prognosis.

Objective To investigate the prognostic significance of serum lactate level and lactate clearance rate for critical illness patients.Methods Two hundred and eighty-six patients with hyperlactacidemia were investigated by analyzing the clinical data,laboratory data and outcomes.Comparison of mortality rate and APACHE Ⅱ score between different stratified levels of serum lactate was carried out.The blood pH,HCO3-,BE,and Lac were compared between survivors and non-survivors in terms of in-hospital death in seven days after admission.The above variables of blood gas analysis were studied in patients with severe hyperlactacidemia as well as the different lactate clearance rates and APACHE Ⅱ scores were compared between survivors and non-survivors.The mortality rates and APACHE Ⅱ scores were compared between high and low lactate-clearance rate groups.Results The mortality rates of different stratified levels of serum lactate (≥2,<4 mmol/L; ≥4,< 10mmol/L; ≥ 10 mmoL/L) were 14.04%,46.67%,78.79%,respectively.As the serum level of lactate increased,the decompensation rate of pH,APACHE Ⅱ score and mortality rate increased consequently.Compared with non-survivors,survivors had a higher lactate clearance rate (P < 0.01),and lower APACHE Ⅱ score (P < 0.01).The high-clearance group had lower mortality rate and 6-hour APACHE Ⅱ score compared with the low-clearance group (P < 0.01),but the initiate levels of serum lactate and APACHE Ⅱ scores were not noticeably different between the two groups (P > 0.05).Serum lactate level had a significant positive relationship with APACHE Ⅱ score (r =0.868,P < 0.01),but lactate clearance rate had a significant reverse relationship with APACHE Ⅱ score (r =-0.823,P < 0.01).Conclusions Both serum lactate levels and early lactate clearance rate had high prognostic value for critical illness patients,and in combination with changes in APACHE Ⅱ score,they could guide clinical treatment and give precise evaluation of the prognosis.

Objective:To investigate the prognostic value of platelet volume indices (PVIs), neutrophil/lymphocyte ratio (NLR) and the combination of these parameters for the neurological function of acute ischemic stroke (AIS) patients after intravenous thrombolysis.Methods:From January 2016 to January 2019, the data of 147 AIS patients with intravenous thrombolysis in the Emergency Department of Peking University People's Hospital who met the diagnostic criteria of AIS were retrospectively analyzed. The patients were divided into two groups according to modified rank in scale (MRS) score: MRS≤2 and MRS≥3. The general information, past medical history and laboratory examination results of each group were compared. Logistic regression analysis was used to analyze the risk factors of poor prognosis of neurological function in AIS patients with thrombolysis.Results:NLR ( OR=1.045, 95% CI: 1.032-2.350, P=0.032), mean platelet volume (MPV) ( OR=4.212, 95% CI:1.074-16.513, P=0.039), MPV×NLR/PLT ( OR=5.711, 95% CI: 1.342-24.298, P=0.018), platelet distribution width (PDW) ( OR=1.015, 95% CI: 1.001-2.372, P=0.032), and NIHSS score ( OR=1.266, 95% CI: 1.111-1.443, P<0.01) were related with poor prognosis neurological function of AIS patients with intravenous thrombolysis. Conclusions:MPV, NLR, MPV×NLR/PLT PDW and NIHSS scores are the risk factors for poor prognosis of neurological function in AIS patients with thrombolysis. MPV×NLR/PLT can predict the neurological severity of AIS after 3 months.

Objective To retrospectively analyze the engraftment, transplant-related complications and survival after unrelated cord blood transplantation (UCBT) in patients with hematologic malignancies. Methods Fifty consecutive patients with hematological malignancies (median age, 19 years; median weight, 53 kg) were treated with UCBT in single center from April 2000 to August 2009. Thirty-nine patients were high-risk or refractory. Double UCB grafts were used for 26 patients, while single UCB graft for 24 patients. Myeloablative conditioning was given to 45 cases and non-myeloablative regimens to 5 cases. All patients were given a combination of cyclosporin A (CsA) and mycophenolate mofetil (MMF) for graft-versus-host disease (GVHD) prophylaxis. Results The median total nucleated cell (TNC) dose was 4.0 (range, 1.95-16.24)×10~7 TNC/ kginfused, and CD34~+ cell dose was 2.74(range, 0.67-29.28)×10~5/kginfused. Forty-two of 50 patients acquired engraftment with implantation rate being 86%. The median time to engraftment (absolute neutrophil count>500/mm~3 and platelets 20 000/L) was 19 and 34 days. The cumulative incidence of neutrophil engraftment by day 42 was 86.3%(95% confidence interval [CI] 0.769-0.957); the cumulative incidence of platelets engraftment by day 120 was 72.3% (95% CI 0.620-0.821). Twenty cases developed acute GVHD, and the incidence of acute GVHD of grades Ⅲ/Ⅳ by day 100 was 7.1%. The incidence of chronic GVHD within 2 years was 17.4%. During a median follow-up period of 22 months (range 4-116), Overall 6-month, 1-year and 2-year survival rate was 66.2%(95% CI 0.590-0.734), 57.4%(95% CI 0.496-0.652), 54.2%(95% CI 0.462-0.622), respectively. For the patients with non-advanced hemotologic malignancies, 6-month, 1-year and 2-year survival rate was 73.2% (95% CI 0.659-0.805), 66.1% (95% CI 0.579-0.743), and 62.2% (95% CI 0.542-0.682) respectively. Five cases relapsed. The cumulative incidence of relapse within 2 years was 16.2% (95% CI 0.099-0.225). Twenty-one cases died mainly due to infection. Conclusion UCBT could be safely and effectively used for adult patients with hematologic malignancies.

Objective:To explore the clinical characteristics, diagnosis and treatment of acute leukemia patients during pregnancy.Methods:The clinical data of 16 cases with acute leukemia during pregnancy from January 2009 to December 2018 in the First Affiliated Hospital of USTC were retrospectively analyzed. The diagnosis and treatment regimens, pregnancy outcome, the early fetus and survival status of patients were also analyzed.Results:All 16 leukemia cases were confirmedly diagnosed and classified by bone marrow puncture, including 13 cases of acute myeloid leukemia (5 cases of non-acute promyelocytic leukemia and 8 cases of acute promyelocytic leukemia) and 3 cases of acute lymphoblastic leukemia. At the time of confirmed diagnosis, 6 patients were in first trimester, 6 cases in second trimester and 4 cases in late trimester. As for pregnancy outcome, 1 patient had natural birthing, 5 patients underwent cesarean operation, 9 patients underwent artificial abortion and 1 patient had spontaneous abortion. Chemotherapy was performed in 15 patients during pregnancy, 11 patients received chemotherapy for treatment of primary disease after pregnancy, 3 patients died during the treatment. During the follow-up of 13 cases, 8 patients survived and 5 patients lost follow-up.Conclusions:Early diagnosis of acute leukemia during pregnancy is very important. Bone marrow puncture should be performed timely to make clear diagnosis when blood routine result is abnormal during antenatal care. Multidisciplinary consultation should be initiated in time, and the best treatment plan should be worked out to guard against serious complications during pregnancy.

Objective To observe the effect of surface electromyographic biofeedback on the pharyngeal phase activities in patients with dysphagia after stroke. Methods Seventy-six consecutive patients with pharyngeal dysphagia after stroke admitted to the departments of rehabilitation and neurology,brain hospital affiliated to nanjing medical university from August 2014 to February 2015 were enrolled retrospectively. After excluding 40 patients,the remaining 36 patients were divided into either a conventional training group (n =19)or a biofeedback group (n =17)by using the random number table. The patients of the conventional training group received swallowing function training only,while those of the biofeedback group also received the surface electromyographic biofeedback treatment on the basis of the therapy program of the conventional training group. The patients of both groups were treated 6 times a week for 4 weeks. The assessment of swallowing angiography,the digital measurement and analysis were performed before and after treatment. The outcome measures included the degree of openness of upper esophageal sphincter (UES),0pharyngeal transit time (PTT),and the maximum displacement of the hyoid bone (HmaxD). Results (1)The proportions of UES complete opening of the conventional training group before and after training were 26. 3% (5 / 19)and 47. 4% (9 / 19)respectively. There was significant difference between before and after training (χ2 = 5. 08, P =0.020). The proportions of UES complete opening of the biofeedback group before and after training were 47.1% (8/ 17)and 82.4% (14/ 17)respectively. There was significant difference between before training and after training (χ2 =11.46,P = 0. 001). There was no significant difference in the degrees of UES complete opening before training between the conventional training group and the biofeedback group (P >0. 05). There was significant difference in the degree of UES complete opening after training between the 2 groups (χ2 =4. 63,P = 0. 040). (2)PTT of the conventional training group before and after training was 0.24 ±0.07 and 0.19 ±0.06 s respectively. PTT of the biofeedback before and after training was 0.23 ±0.06 and 0. 15 ± 0. 05 s. There was significant difference between before training and after training (F = 154. 50,P = 0. 000). There was no significant difference in PTT before training between the conventional training group and the biofeedback group (P > 0. 05). There was significant difference in PTT after training between the 2 groups (F =4.66,P = 0. 038). (3)The HmaxD distances of the conventional training group before and after training were 0. 5 ± 0. 4 and 0. 9 ± 0. 4 cm respectively,the PTT of the biofeedback training before and after training was 0. 6 ± 0. 4 and 1. 3 ± 0. 6 cm respectively. There was significant difference between before training and after training (F = 137. 56,P = 0. 000). There was no significant difference in the HmaxD distance of the conventional training group and the biofeedback training group before training (P > 0. 05). There was significant difference in the HmaxD distance after training between the 2 groups (F = 4. 29,P = 0. 033). Conclusion The surface electromyographic biofeedback therapy in combination with the conventional swallowing training for the treatment of dysphagia after stroke has the synergistic efficacy.

Objective To observe the character of amplitude of myoelectric activity with surface electromyography (sEMG) on pharyn-geal swallowing in healthy middle-aged and elderly people. Methods From January, 2015 to January, 2016, 78 healthy subjects were separat-ed into middle-aged group (38~60 years old, n=38) and elderly group (61~82 years old, n=40). The amplitudes of sEMG activity of related muscles under different swallowing modes were recorded by sEMG technique and analysis system. The root mean square (RMS) was ana-lyzed. Results There was significant difference in RMS among different swallowing modes (F>105.120, P<0.001). There was no difference in RMS between two muscles under all the swallowing modes in both groups (t<1.135, P>0.05). There was no difference between two groups in both muscles under relax and dry swallow (t<1.412, P>0.05), and was different under water swallow and continuous drinking (t>2.700, P<0.05). Conclusion sEMG could be used for analyzing the characteristics of amplitude of myoelectric activity in healthy mid-dle-aged and elderly people during pharyngeal swallowing in different swallowing modes, that can be used to evaluate and screen swallow-ing and dysphagia in clinic.

Objective To assess the histological characteristics of cervical cancer using intravoxel incoherent motion magnetic resonance imaging ( IVIMMRI) and to investigate the performance of IVIMMRI in evaluation of the efficacy of concurrent chemoradiotherapy in the treatment of intermediate/advanced cervical cancer. Methods Pelvic MRI scans, containing T2WI, IVIM (14 b values, b=0?1 000 s/mm2), and contrast?enhanced T1 scans were performed in 23 patients pathologically diagnosed with intermediate/advanced cervical cancer ( stage ≥Ⅱb ) before chemoradiotherapy, after two and four weeks of treatment, and at the end of treatment. The IVIMMRI data were processed with the bi?exponential model to generate three parameters, containing pure diffusion coefficient ( D ) , pseudodiffusion coefficient ( D?) , and perfusion fraction ( f ) . Apparent diffusion coefficient ( ADC ) was obtained using the mono?exponential model. The IVIMMRI parameters were measured at each time point and their dynamics and correlation were analyzed. Results The ADC, D, and f values were significantly higher after complete treatment ( 0?96 × 10-3 vs. 1?77 × 10-3 mm2/s, P=0?000;0?76 × 10-3 vs. 1.34± 0?12 × 10-3 mm2/s, P=0?000;0?14% vs. 0?24%, P=0?012). The above three values significantly increased after two weeks of treatment (all P=0?000) and kept increasing until the end of the treatment. In contrast, the D? value was reduced from the second week to the end of the treatment. Conclusions IVIMMRI can monitor the dynamic functional changes and early tumor responses during chemoradiotherapy for cervical cancer, which holds promise for clinical application.
