OBJECTIVE:
To evaluate the predictive accuracy of the triage early warning score (TEWS) in the prognosis and emergency treatment for trauma patients admitted to the emergency department (ED).
METHODS:
A total of 456 trauma patients (>12 years old) admitted to ED at an education and research hospital in approximately 4 months were prospectively studied. Th e TEWS was recorded in all patients. Th e primary end-point was during 28 days and the emergency responses (such as cardiopulmonary resuscitation/electrical defibrillation, mechanical ventilation) in the ED.
RESULTS:
Patients with TEWS less than or equal to 9, from 10 to 13, or greater or equal to 14 had mortality rates of 0.98%, 52.63%, or 80%, respectively. An increase in 1 point within the range of 17-point TEWS would be associated with an odds ratio (OR) of 2.14 for death [95% confidence interval (CI): 1.759 to 2.604]. In predicting mortality rates during 28 days, the cut-point was greater than 8, the sensitivity was 87.10% (95% CI: 70.2% to 96.4%), the specificity was 92.47% (95% CI: 89.5% to 94.8%), and the areas under the receiver operating characteristic curves (AUCROC) was 0.929 (95% CI: 0.902 to 0.951). Th e AUCROC of TEWS in predicting the emergency responses for CPR/electrical defibrillation application or mechanical ventilation was 0.969 (95% CI: 0.949 to 0.983) or 0.897 (95% CI: 0.865 to 0.923), respectively.
CONCLUSION
TEWS is effective in predicting the prognosis and emergency treatment for trauma patients admitted to ED.

Objective:To explore the clinical outcome of early endoscopic realignment with flexible cystoscope for pelvic fracture urethral injury.Methods:We retrospectively collected and analyzed the clinical data of patients with pelvic fracture urethral injuries in ER of Beijing Jishuitan Hospital from March 2018 to June 2022.Seventy-six male patients with PFUI were reviewed and 60 patients were included due to the integrity of data collected. The patients were divided into early endoscopic realignment (EER) group and suprapubic cystostomy (SC) group according to the acute management. There were 33 patients and 27 patients in EER group and SC group, respectively. The age of the patients were (42.2±13.8)years and (44.1±15.0) years in EER group and SC group, respectively. The causes of the injuries were car accident, falling and crush, the percentage of the patients were 60.6%(20 cases), 33.3%(11 cases), 6.1%(2 cases) and 55.6%(15 cases), 44.4%(12 cases), 0 in EER group and SC group, respectively. The difference between two groups was statistically insignificant. The procedure of EER began with a cystostomy guided by B ultrasound, then an antegrade cystoscopy was performed through the cystostomy while negociating the bladder neck to the proximal side of injured urethra. A ureteral stent was inserted into the broken urethra and retrieved by a forceps through retrograde urethroscopy with another flexible cystoscope. We inserted a guidewire into the ureteral stent before removing it and placed a 16F urethral catheter along the guidewire. We analyzed the difference between two groups including the incidence, the length and the management of urethral stricture and the complexity of urethroplasty if needed. The simple urethroplasty was defined as performing anastomosis after dissection of the bulbar urethral and removing the scar tissue, while the procedure was defined as complex urethroplasty if ancillary procedures, such as separating the corporal bodies and partial pubectomy, was needed.Results:The EER group and SC group had 33 patients and 27 patients, respectively. The mean operation time of EER was (24.5±7.0)minutes and there was no intra-operative complications. Postoperatively, 4 cases of bleeding and 2 cases of UTI were found, which were successfully treated by conservative managements. Twenty-eight out of 33 patients(84.8%) in EER group developed urethral stricture and the mean length of it was (3.10±1.20)cm. However, all patients in SC group developed urethral stricture (100.0%) with the mean stricture length of (3.83±1.18)cm. The difference between two groups in term of the length of stricture was statistically significant ( P=0.026). 24 patients(85.7%) in EER group were treated by urethroplsty, 2 patients(7.1%) with endoscopic urethrotomy and 2 patients (7.1%) with dilation. All were treated with urethroplasty but 2 patients with endoscopic in SC group. In EER group, 8 strictures (33.3%)finished with simple urethroplasty and 16 strictures (66.7%) with complex urethroplasty.While in SC group, 6 strictures(24.0%) completed with simple urethroplasty and 19 strictures (76.0%)with complex urethroplasty. The complexity of urethroplasty performed in EER group was not statistically significant when compared with it in SC group( P=0.538). Conclusions:The procedure of EER with flexible cystoscope is reliable and safe. Most patients with formed urethral stricture after PFUI would be treated with urethroplasty. EER can reduce the urethral stricture formation and may decrease the need of the ancillary procedures during the urethroplasties if needed.

OBJECTIVE:
To investigate the current status on knowledge for unintentional injury and risky behavior among school-age children in Changsha, China, and to provide scientific evidence for the preventive strategies.
METHODS:
A cross-sectional study was conducted on 866 students who were between 6 and 12 years old in Changsha. Two primary schools were selected by stratified cluster random sampling from all primary schools of Changsha city to collect the information regarding knowledge for unintentional injury and risky behavior occurring in the 6-month period before the survey.
RESULTS:
The mean score for knowledge of unintentional injury was 11.83±2.38. The levels of knowledge for unintentional injury differed significantly in child's age, parents' education background and child's injury history (P<0.05). The child's knowledge level was correlated with child's age, mother's education, child's injury history. The mean score for risky behavior was 17.61±10.35. The levels of risky behavior differed significantly in child's gender, father's age to have the child, parents' marriage status, whom does/do child live with, child's injury history and medical history since the birthday (P<0.05). There was a linear regression relationship between risky behavior and child's injury history, parents' marriage status, child's gender. There was no significant correlation between knowledge and risky behavior (P>0.05).
CONCLUSION
It is a common phenomenon in school-age children who are lack of the knowledge for unintentional injury and risky behavior. This study provides useful information on the risk factors for unintentional injury and risky behavior, which would be significant for prevention program.

Tumors are new organisms formed by uncontrollable cell proliferation of local tissues driven by various oncogenic factors. The cause of tumors is unknown with life-threating outcome. Tumors can be classified into benign tumors, borderline tumors, and malignant tumors according to their pathological properties. Among them, malignant tumor is commonly known as cancer, with no specific medicines or reliable cure means, so this is a hot spot and difficult point in current medical research. In ancient literatures, there are many records about the efficacy of Chinese herbal medicine in treating tumor, and modern pharmacological researches have shown that more and more active ingredients of traditional Chinese medicine(TCM) have gradually highlighted their inhibitory effect on various types of tumor.

OBJECTIVE To study the pharmacological substance basis of Shaoyao gancao decoction for relieving acute and chronic pain. METHODS The antispasmodic effect of Shaoyao gancao decoction, ethyl acetate extract of Shaoyao gancao decoction and its effluent part of macroporous resin and 90% ethanol elution part of macroporous resin (the concentration of 4 drugs was 13.44 g/mL according to crude drug) was observed by in vitro small intestine tension test in rats. The acetic acid writhing test was conducted in mice to evaluate the analgesic effects of macroporous resin efflux site and macroporous resin 90% ethanol elution site (the dosage of 2.4 g/kg according to crude drug). The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL- 1β), prostaglandin E2 (PGE2) and cyclooxygenase-2 (COX-2) in serum of mice were detected. The serum prototype and metabolites of mice after intragastric administration of macroporous resin 90% ethanol elution site were identified by high performance liquid chromatogre-time-of-flight mass spectrometry. RESULTS In vitro experiment showed that 90% ethanol eluting part of macroporous resin represented the best antispasmodic effect, and the inhibitory rate of small intestine tension was significantly higher than macroporous resin efflux site of Shaoyao gancao decoction (P<0.05) without statistical significance, compared with Shaoyao gancao decoction (P>0.05). In the acetic acid writhing experiment, compared with model group, the writhing times of mice in the macroporous resin 90% ethanol elution part group were reduced significantly (P<0.05), the writhing latency was prolonged significantly (P<0.05), and the levels of COX-2, IL-1β, PGE2 and TNF-α in serum were decreased significantly (P<0.05). Ten kinds of protoproducts including paeoniflorin and glycyrrhizic acid were identified from serum of mice, and twenty-two kinds of metabolites including hydroxylated glycyrrhizin and glucosylated liquiritin were identified. CONCLUSIONS The effective part of Shaoyao gancao decoction for relieving acute and chronic pain is 90% ethanol elution part prepared by macroporous resin from the ethyl acetate extract. Ten components, including glycyrrhetinic acid and paeoniflorin, may be the basis of its pharmacological substances.
