Objective To analyze rick factors for postoperative recurrence of spontaneous pneumothorax surgery. Methods The clinic characteristics of 1128 patients who received spontaneous pneumothorax surgery in Tianjin Chest Hospital were collected from January 2009 to March 2015. The relationship between clinic characteristics and the pulmonary bullae was analyzed. Logistic regression analysis was used to assess factors affecting the postoperative relapse of spontaneous pneumothorax. Results The pulmonary bullae were found in 877 patients of 1128 during the operation. The incidence of pulmonary bullae was significantly high in patients with age below 25 years compared with patients over 25 years (P<0.05). The duration of surgery was significantly longer in patients with pulmonary bullae compared with that of patients without pulmonary bullae (P<0.05). Postoperative recurrence occurred in 21 cases, with a recurrence rate of 1.86%. Logistic regression analysis showed that pulmonary bullae, pleurodesis without pleura friction, delayed drainage duration (> 3 d) were independent risk factors of postoperative recurrence for spontaneous pneumothorax (P<0.05). Conclusion Pulmonary bullae, pleurodesis without pleura friction and delayed drainage duration are risk factors of postoperative recurrence for spontaneous pneumothorax, which should be paid more attention in clinic.

Objective To explore the effects of early glucocorticoids (GC) therapy on the outcome of patients with acute respiratory distress syndrome (ARDS). Methods The clinical data of all ARDS patients admitted from January 2008 to December 2011 in Chengdu Military General Hospital of Chinese PLA were retrospectively analyzed. The adult patients whose diagnosis was in accord to the Berlin ARDS diagnostic criteria published in 2012 were enrolled, and based on whether using glucocorticoid or not, they were divided into GC group and non-GC group. All the patients in GC group received low dosage of intravenous GC within 48 hours after the onset of ARDS, including different kinds of GC, methylprednisolone, dexamethasone and hydrocortisone (hydrocortisone dosage < 5 mg·kg-1·d-1, the dosage of former two kinds of GC being converted to that of hydrocortisone), and the therapeutic course of the two groups was 7 to 21 days. The patients in non-GC group received no GC therapy after the occurrence of ARDS. The duration of mechanical ventilation, the length of intensive care unit (ICU) stay and totally in hospital, medical cost and 28-day survival rate were compared between the two groups. Results One hundred and seventeen patients with ARDS were collected, including 56 cases (47.86%) in GC group and 61 cases (52.14%) in non-GC group. The duration of mechanical ventilation in GC group was significantly shorter than that in non-GC group [days:0 (0, 2.50) vs. 2.00 (0, 2.50), Z=2.015, P=0.044]. The 28-day survival rate in GC group was significantly higher than that in non-GC group [71.43%(40/56) vs. 50.82%(31/61),χ2=5.198, P=0.023]. There were no significant differences in the length of ICU stay [days:7.50 (2.00, 11.00) vs. 4.00 (1.00, 9.00), Z=1.879, P=0.060] and stay totally in hospital [days:16.00 (10.00, 27.75) vs. 15.00 (7.00, 28.00), Z=0.592, P=0.552] between GC group and non-GC group. However, the medical cost in non-GC group was significant lower than that in GC group [10 thousand Chinese yuan:3.15 (1.51, 5.78) vs. 4.39 (1.66, 10.88), Z=2.204, P=0.028]. Conclusion The early GC therapy may improve the outcome of patients with ARDS, especially beneficial to the 28-day survival rate.

BACKGROUND: Combined use of multiple interventions for different targets play superimposed or synergistic effects,which has become the current idea for spinal cord injury treatment.OBJECTIVE: To investigate the synergistic effects of low doses of 17-β estradiol combined with bone marrow mesenchymal stem cells (BMSCs) transplantation on the recovery of motor function and inflammatory reactions after spinal cord injury in rats.METHODS: The 10 of 70 male Sprague-Dawley rats served as sham group in which the spinal cord was only exposed but with no treatment, and the rest 60 rats were used to make animal models of spinal cord injury using modified Allen's method and then randomized into four groups (n=15 per group): model, estrogen, stem cell and combined treatment groups. Rats in the stem cell and combined treatment groups were given BMSCs transplantation at injured side; rats in the estrogen and combined treatment groups were given intramuscular injection of 17-β estradiol at 1 and 24 hours after modeling. At 1, 3, 5 and 7 days after modeling, rat functional recovery was evaluated by the Basso, Beatlie, Bresnahan score. The expressions of interleukin-1β and tumor necrosis factor-α in the injured spinal cord were detected by ELISA at 6, 12, 24, and 72 hours after modeling. Apoptosis in nerve cells was observed using TUNEL staining. RESULTS AND CONCLUSION: The Basso, Beatlie, Bresnahan scores were declined significantly after modeling,increased at 5 and 7 days after stem cell transplantation, estrogen treatment or their combined treatment (P < 0.05),especially in the combined treatment group (P < 0.05). The levels of interleukin-1β and tumor necrosis factor-α were elevated gradually after spinal cord injury (P < 0.05), but the levels decreased significantly at 12 and 24 hours in stem cell,estrogen and combined treatment groups (P < 0.05), and this decrease trend was more significant in the combined treatment group compared with the stem cell and estrogen groups (P < 0.05). At 72 hours after modeling, the rate of TUNEL positive cells was highest in the model group (P < 0.05) and lowest in the combined treatment group (P < 0.05).To conclude, the combined use of low doses of 17-β estradiol and BMSCs transplantation can facilitate the recovery of motor function after spinal cord injury by effectively inhibiting apoptosis in nerve cells.

ObjectiveTo develop and validate a predictive model to individually predict the risk of patients with stroke in the eICU Collaborative Research Database for early clinical identification and intervention. MethodIndividual patient data (200 859 cases) from a national multicenter cohort study (eICU database) were selected, and the patients with stroke in neurological diseases (9 037 cases) were selected for statistical analysis. The main outcome was hospital mortality. The Glasgow Coma scale (GCS) was used to divide all patients with stroke into stroke in meridian and stroke in viscera (GCS≤14 for stroke in viscera and GCS=15 for stroke in meridian). The patients were then divided into a training set and a test set according to 7∶3, respectively, to evaluate the differences in hospital mortality between the two groups. The multivariate logistic regression was used to analyze the related factors affecting the prognosis of the two groups, and a predictive model was established. Receiver operator characteristic (ROC) curves were used to assess the discrimination of the predictive model. ResultThe predictive model based on 9 037 patients with stroke was established. The predictors of the stroke in meridian (4 475 cases) included pulmonary infection, mechanical ventilation, acute physiology, and chronic health status scoring system Ⅳ (APACHE Ⅳ) score. The predictors of the stroke in viscera (4 562 cases) included anticoagulation therapy (AT), mechanical ventilation, acute physiology, and APACHE Ⅳ score. According to the predictors, the predictive models of the stroke in meridian and the stroke in viscera were constructed, respectively. The areas under the curve (AUC) of ROC of the training set and the test set of the predictive models of the stroke in meridian were 0.845 [95% confidence interval (CI) (0.811, 0.879)] and 0.807 [95% CI (0.751, 0.863)], respectively. The areas under the ROC curve of the training set and test set of the predictive models of the stroke in viscera were 0.799 [95% CI (0.781, 0.817)] and 0.805 [95% CI (0.778, 0.832)], respectively. The AUC of the predictive model of the training set and the test set were both above 0.7. ConclusionThe model established in this study can conveniently, directly, and accurately predict the hospital mortality risk of patients with stroke. Physicians and other healthcare professionals can use this predictive approach to provide early care planning and clinical interventions for patients with stroke during their hospital stay.
