BACKGROUND: Spinal somatosensory evoked potential(SEP) monitoring is widely used intraoperatively due to the easiness to operate and its reliability.OBJECTIVE: This study was designed to assess the significance of improving SEP signals in intraoperative spinal monitoring on predicting the post-operative spinal function.DESIGN: A non-randomized concurrent controlled study was conducted on selected patients.SETTING: This study was conducted at the Orthopedic Department of Peking Union Medical College Hospital.PARTICIPANTS: Totally 34 patients with cervical spondylosis underwent surgical treatment at the Orthopaedic Department of Peking Union Medical College Hospital were selected from January to October in 2001. Of all the patients, 24 underwent anterior decompression and fusion, 3 single door operation and 7 double door operation. According to the variance of intraoperative SEP, the patients were divided into the improvement group(12 cases)and the non-improvement group(22 cases).METHODS: All the patients' neurologic deficits were assessed according to the Japanese Orthopaedic Association scoring system(JOA score), prior to operation and postoperative week 1, 2, and 4 and month 3, 6. Each patient received the intraoperative spinal SEP monitoring. The variance of SEP signals in amplitude and latency were classified as improvement(an increase in amplitude of 50% or more, or a decrease in latency of 10% or more), decrease(a decrease in amplitude of 50% or more, or an increase in latency of 10% or more), and no improvement.MAIN OUTCOME MEASURES: JOA scores were calculated in two groups in the study at all time points.RESULTS: All the 34 patients entered the statistical analysis procedure. In postoperative week 1 and week 2, the improvement group showed a larger increase in JOA score than the non-improvement group did[improvement group:(14.08±1.44), (14.17±1.11) points; no improvement group:( 12.73 ± 1.42), ( 12.86 ± 1.28)points, P < 0.05]. In postoperative week 4, month 3 and month 6, both groups showed an increase in JOA scores [improvement group: (14.00±1.04), (13.58±1.08), (13.68±1.61)points; no improvement group: (13.82 ± 1.01), (13.41 ± 1.22), (13.41± 1.47)points], but there was no significant difference( P > 0.05).CONCLUSION: Improvement of intraoperative SEP can be used to predict the good early clinical outcomes in surgery for cervical spondylosis.

Objective To evaluate clinical features,therapeutic effects and outcomes of patients with non-human immunodeficiency virus(HIV)-infected cryptococcal meningitis treated with fluconazole or fluconazole and flucytosine.Methods Twenty-four cases of non-HIV-infected cryptococcal meningitis(fluconazole with or without flucytosine as initial therapy)in Huashan Hospital,Fudan University from 1997 to 2007 were retrospectively reviewed.Clinical manifestations,therapeutic effects and outcomes of the patients were collected.Results Fluconazole was administered with median dosage of 400 mg/d,for a median duration of 20.5 days.After fluconazole initial therapy for 2 weeks,16.7% showed partial response,83.3% showed no response,and the overall response rate was 16.7%.After 10 weeks,33.3% showed partial response,29.2% showed complete response,16.7% showed no response,and the overall response rate was 62.5%.Mortality at week 10 was 20.8%.Twenty-two patients who failed to respond to initial therapy were switched to other antifungal drugs(amphotericin B,amphotericin B colloidal dispersion,itraconazole)or other fluconazole containing combined therapy.Eleven out of the 24 patients died during one-year follow-up,8 of whom died of eryptococcal meningitis,and 3 died of other diseases.Conclusions The initial therapy of fluconazole with or without flucytosine is inefficient,and most of the patients need other antifungal drugs because of initial therapy failure.Therefore,fluconazole might not be appropriate for initial therapy in non-HIV-infected cryptococcal meningitis.

Background::Hypothermia therapy has been suggested to attenuate myocardial necrosis; however, the clinical implementation as a valid therapeutic strategy has failed, and new approaches are needed to translate into clinical applications. This study aimed to assess the feasibility, safety, and efficacy of a novel selective intracoronary hypothermia (SICH) device in mitigating myocardial reperfusion injury.Methods::This study comprised two phases. The first phase of the SICH was performed in a normal porcine model for 30 minutes ( n = 5) to evaluate its feasibility. The second phase was conducted in a porcine myocardial infarction (MI) model of myocardial ischemia/reperfusion which was performed by balloon occlusion of the left anterior descending coronary artery for 60 minutes and maintained for 42 days. Pigs in the hypothermia group ( n = 8) received hypothermia intervention onset reperfusion for 30 minutes and controls ( n = 8) received no intervention. All animals were followed for 42 days. Cardiac magnetic resonance analysis (five and 42 days post-MI) and a series of biomarkers/histological studies were performed. Results::The average time to lower temperatures to a steady state was 4.8 ± 0.8 s. SICH had no impact on blood pressure or heart rate and was safely performed without complications by using a 3.9 F catheter. Interleukin-6 (IL-6), tumor necrosis factor-α, C-reactive protein (CRP), and brain natriuretic peptide (BNP) were lower at 60 min post perfusion in pigs that underwent SICH as compared with the control group. On day 5 post MI/R, edema, intramyocardial hemorrhage, and microvascular obstruction were reduced in the hypothermia group. On day 42 post MI/R, the infarct size, IL-6, CRP, BNP, and matrix metalloproteinase-9 were reduced, and the ejection fraction was improved in pigs that underwent SICH.Conclusions::The SICH device safely and effectively reduced the infarct size and improved heart function in a pig model of MI/R. These beneficial effects indicate the clinical potential of SICH for treatment of myocardial reperfusion injury.

We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia (GTN). In this trial (NCT01823315), 276 patients were analyzed. Patients were allocated to three initiated regimens: single-course methotrexate (MTX), single-course MTX + dactinomycin (ACTD), and multi-course MTX (control arm). The primary endpoint was the complete remission (CR) rate by initial drug(s). The primary CR rate was 64.4% with multi-course MTX in the control arm. For the single-course MTX arm, the CR rate was 35.8% by one course; it increased to 59.3% after subsequent multi-course MTX, with non-inferiority to the control (difference -5.1%,95% confidence interval (CI) -19.4% to 9.2%, P = 0.014). After further treatment with multi-course ACTD, the CR rate (93.3%) was similar to that of the control (95.2%, P = 0.577). For the single-course MTX + ACTD arm, the CR rate was 46.7% by one course, which increased to 89.1% after subsequent multi-course, with non-inferiority (difference 24.7%, 95% CI 12.8%-36.6%, P < 0.001) to the control. It was similar to the CR rate by MTX and further ACTD in the control arm (89.1% vs. 95.2%, P =0.135). Four patients experienced recurrence, with no death, during the 2-year follow-up. We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.
