ABSTRACT

BACKGROUND@#We aimed to describe and analyze the pre-hospital emergency medical service (EMS) in Beijing and provide information for the government and medical institutions to optimize EMS.@*METHODS@#We collected all pre-hospital emergency data in Beijing from 2008 to 2017. The chief complaint in each case was classified according to the Medical Priority Dispatch System (MPDS). The sites' administrative districts were determined through geo-encoding of addresses and then classified into four functional regions. We analyzed the demand for EMS, emergency response times (ERT), and disease spectrum for Beijing as a whole, and for each functional region.@*RESULTS@#A total of 4,192,870 pre-hospital EMS cases met the inclusion criteria, with a significant increase (P < 0.001) of 51.60% from 2008 to 2017. EMS demand was positively associated with population (r = 0.946, P < 0.001). The pre-hospital EMS demand rate was 1907.05 in 2008 and 2172.23 in 2017 per 100,000, with no significant change (P = 0.57). ERT increased significantly (P = 0.001), from 19.18 min in 2008 to 24.51 min in 2016. According to MPDS classifications, the demand for pre-hospital care increased for 14 diseases, remained stable for 19, and decreased for only 1 disease. Cases of injury-related disease increased significantly from approximately 90,000 in 2017, accounting for 20% of all pre-hospital EMS cases, and the demand rate decreased in the core region but increased in the sub-urban regions. Cases of heart problems and stroke/transient ischemic attack also increased significantly in the four functional regions, with the highest demand rate in the Core Functional Region.@*CONCLUSIONS@#More resources and effort should be devoted to pre-hospital EMS according to the increased pre-hospital EMS demand and prolonged ERT in Beijing over our 10-year study period. Changes in disease spectrum and differences between functional regions should also be considered.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effect of short-course kidney-invigorating therapy on near-term semen quality in asthenozoospermic men with kidney deficiency.</p><p><b>METHODS</b>Based on the differential types in traditional Chinese medicine, 121 asthenozoospermia patients received at our clinic of andrology were divided into groups A (kidney-yin deficiency), B (kidney-yang deficiency) and C (spleen and kidney deficiency), and treated with Yougui Decoction plus Wuziyanzong Pills, Jinkuishenqi Pills plus Wuziyanzong Pills, and Shizi Decoction plus Liujunzi Decoction, respectively, all given once daily for 4 weeks. Sperm parameters of the patients were analyzed with the computer-assisted sperm analysis system before and after treatment and compared among the three groups.</p><p><b>RESULTS</b>The baseline sperm concentrations in groups A, B and C ([70.4 +/- 38.6], [73.5 +/- 40.2] and [56.0 +/-34.4] x 10(6)/ml) showed no significant differences from those after medication ([74.4 +/- 32.6], [67.0 +/- 30.8] and [58.6 +/- 24.6] x 10(6)/ml) (P > 0.05). The percentages of grade a sperm in the three groups were (12.9 +/- 5.3)%, (13.7 +/- 7.7)% and (12.9 +/- 6.4)% respectively after treatment, significantly higher than (9.9 +/- 6.7)%, (9.3 +/- 5.4)% and (9.0 +/- 6.8)% before treatment (P < 0.05), and so were the percentages of grade a + b sperm ([37.4 +/- 10.2 ]%, [35.7 +/- 13.7]% and [35.9 +/- 12.3]% after treatment versus [29.6 +/- 13.2]%, [27.5 +/- 10.4]% and [28.3 +/- 12.1]% before treatment, P < 0.05). All the three groups showed significantly increased sperm motility after treatment ([53.8 +/- 10.5]%, [52.6 +/- 15.2]% and [51.1 +/- 13.1]%) as compared with the baseline levels ([44.3 +/- 14.0]%, [43.5 +/- 15.0]% and [42.4 +/- 14.9]%) (P < 0.05). The cure rate and total effectiveness rate were significantly higher in group B than in A (P < 0.05), but had no significant differences between either A and C or B and C (P > 0.05).</p><p><b>CONCLUSION</b>Short-course kidney-invigorating therapy can significantly improve near-term semen quality in asthenozoospermic men with kidney asthenia, especially in those with kidney-yang deficiency, and it has no obvious adverse effects.</p>

ABSTRACT

<p><b>BACKGROUND</b>Road traffic injuries (RTIs) are a worldwide issue associated with increasing development and motorization. However, statistical studies do not include any analyses of Beijing's geriatric population. Using data from the Beijing Emergency Medical Center, we present the main characteristics of traffic injuries involving the elderly in Beijing. We also provide objective information for those concerned with the safety of traffic systems and the prevention of traffic injuries.</p><p><b>METHODS</b>In a longitudinal, retrospective study, data were collected on 1706 victims aged 65 years and older who sustained traffic injuries in Beijing between 2004 and 2010. Personal information, time of injury event, emergency care response time, road user type, striking vehicle type, injury site, and severity of injury were analyzed using χ(2) tests and Logistic regression analysis.</p><p><b>RESULTS</b>The annual rate of traffic injuries was 21.80 per 100 000 elderly people in Beijing, and the morbidity rate decreased from 2004 to 2010 (P < 0.001). The mean age was (72.92 ± 5.67) years, and 911 (53.40%) of the victims were male. The majority of victims sustained head and lower limb injuries and were classified as being of medium severity. Traffic collisions occurred most frequently in the daytime excluding rush hours; these collisions included being hit by a car (85.64%) and pedestrian victim injuries (79.19%). Our statistical analysis found three factors for injury severity: abdominal injuries (P < 0.001), number of injury sites (P = 0.027), and head injuries (P = 0.034). The decline in traffic injuries is due to a decrease in victims aged 65-74 years and pedestrians; the severity of RTIs also decreased.</p><p><b>CONCLUSIONS</b>This study highlights the declining trend in traffic injuries among older adults in Beijing. However, traffic injuries remain a serious public health problem for the elderly and effective measures are required to reduce their incidence.</p>

ABSTRACT

<p><b>BACKGROUND</b>Nucleus pulposus of intervertebral discs has proinflammatory characteristics that play a key role in neuropathic pain in lumbar herniated intervertebral disc. One of the most commonly used animal models (the traditional model) of non-compressive lumbar herniated intervertebral disc is created by L4-L5 hemilaminectomy and the application of autologous nucleus pulposus to cover the left L4 and L5 nerve roots in rats. However, such procedures have the disadvantages of excessive trauma and low success rate. We proposed a modified model of non-compressive lumbar herniated intervertebral disc in which only the left L5 dorsal root ganglion is exposed and transplanted with autologous nucleus pulposus following incision of epineurium. We aimed to compare the modified model with the traditional one with regard to trauma and success rate.</p><p><b>METHODS</b>Thirty Sprague-Dawley male rats were randomized into three groups: sham operation group (n = 6), traditional group (n = 12), and modified group (n = 12). The amount of blood loss and operative time for each group were analyzed. The paw withdrawal threshold of the left hind limb to mechanical stimuli and paw withdrawal latency to heat stimuli were examined from the day before surgery to day 35 after surgery.</p><p><b>RESULTS</b>Compared with the traditional group, the modified group had shorter operative time, smaller amount of blood loss, and higher success rate (91.7% versus 58.3%, P < 0.05). There was no decrease in paw withdrawal latency in any group. The sham operation group had no decrease in postoperative paw withdrawal threshold, whereas the modified and traditional groups had significant reduction in paw withdrawal threshold after surgery (mechanical hyperalgesia).</p><p><b>CONCLUSIONS</b>Transplantation of nucleus pulposus onto the L5 dorsal root ganglion following incision of epineurium in rats established an improved animal model of non-compressive lumbar herniated intervertebral disc with less trauma and more stable pain ethology.</p>

ABSTRACT

BACKGROUND: Beijing successfully hosted the 2008 Olympic Games, and the services including medical services were widely appreciated by both participants and visitors. We retrospectively analyzed the quality of the medical services provided to athletes, spectators, VIPs, and the workforce during the Beijing 2008 Olympic Games. The information thus gathered would be useful for planning strategies for managing mass gatherings. METHODS: Medical encounter forms filled during the Beijing 2008 Olympic Games were retrospectively reviewed. Descriptive statistics was used to characterize the data by accreditation and diagnostic categories. RESULTS: A total of 22892 medical encounters were documented during the Beijing 2008 Olympic Games. Among them, 10549 (46.08%) involved the workforce, 3365 (14.70%) athletes, 3019 (13.19%) spectators, 585 (2.56%) members of the media, 1065 (4.65%) VIPs, and 4309 (18.82%) others. Of the 22892 cases, physical injury accounted for 27.90% (6386), respiratory disease 18.21% (4169), and heat-related illnesses 2.68% (615). CONCLUSIONS: Preparations of the medical service for the Beijing 2008 Olympic Games were made for 7 years, and the service provided has been praised worldwide. This study provides valuable information that may be useful for planning medical services for upcoming Olympic Games, including the London 2012 Olympic Games and other mass gatherings.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effects of Stragalus membranaceus injection on nitric oxide and endothelin levels of intestinal mucosa in reperfusion injury after hemorrhage shock.</p><p><b>METHOD</b>32 SD rats were randomly divided into four groups: normal group, model group, low dosage group, (treated with Astragalus membranaceus 10 g x kg(-1)); high dosage group (treated with Astragalus membranaceus 20 g x kg(-1)). Models of hemorrhagic shock for 60 minutes and reperfusion for 90 minutes were created. The animals were administrated 3 mL therapeutic solution before reperfusion. At the end of study, intestinal pathology was observed, and the concentration of lactic acid (LD), nitric oxide (NO), endothelin (ET) of intestinal mucosa were detected.</p><p><b>RESULT</b>The intestinal pathology showed that intestinal mucosa epithelial cells damage in model group was severe, in low dosage group was medium, in high dosage group was slight, and no obvious damage was found in normal group. The concentration of LD and NO of small intestine mucous membrane in model group and low dosage group were significantly higher than those in high dosage group and normal group (P < 0.05), but there were no significant differences between high dosage group and normal group (P > 0.05). The concentration of ET of small intestine mucous membrane in model group was the highest of the four groups (P < 0.05). The concentration of ET in low dosage group was significantly higher than that in high dosage group and normal group (P < 0.05), but there were no significant differences between high dosage group and normal group (P > 0.05).</p><p><b>CONCLUSION</b>Stragalus membranaceus injection can reduce small intestine mucous damage by protecting endothelium function in injury after hemorrhage shock-reperfusion.</p>
