Objective To detect the epidemiologic features of pediatric patients with fall from height injury in an effort to provide a reference for prevention and scientific treatment.Methods Data of pediatric patients with fall from height injury treated from January 2011 to December 2012 were collected in the form of questionnaires.Epidemiologic features and relationship of associated factors were measured.Results Pediatric fall injury occurred very often in warmer season,namely on April and May,and in a day,it was more likely to happen when parents slacked at noon and night.Stairs and balconies were the most common sites of falls and head was most vulnerable to the injury.Falling height was the primary factor to the severity of injury.Conclusion To strengthen the protection reform in key areas,the supervision in peak time for falls and the care to children of the migrant workers can reduce fall injury in a certain extent.

Objective To determine the effect of fast passage for patients' access to the emergency department of hospital on rescuing and triaging the traumatic casualties referred from the site of accident by collision between two bullet trains occurred at Wenzhou station on 23 July 2011 in order to accumulate experience of treating large number of traumatized casualties happened in a major accident or disaster.Methods A retrospective study was carried out to collect the data including the different courses of treatment for various types of injury in casualties and the length of stay of traumatized patients with different degrees of severity in the emergency department after casualties entered into the emergency department of hospital via fast passage.Results There were 136 traumatic casualties referred to hospital within 72 hours after the bullet train accident occurred at Wenzhou station.The average length of stay of patients with uncomplicated single injury in the hospital was 27min,and the average length of stay of 108 patients with multiple injuries in the emergency department was 62 min.In last year,the annually average length of stay of casualties in emergency department was 50 min longer when there was no fast passage available for patient to enter into.Conclusions The fast passage for casualties entering into emergency department not only guarantees the traumatized patients rescued in no time after bullet train accident but also shortens the length of stay in the Emergency Department.

Objective To analyze the injury features of the wounded in the bullet train crash in July 23,2011 in Wenzhou of Zhejiang and explore treatment experience.Methods A total of 177 cases who were injured or died in the 7.23 Wenzhou bullet train crash were involved in the study.The age,gender,injury types,injury regions and injury severity were analyzed by using Trauma Database System V3.0 ( produced by China Trauma Data Center of Third Military Medical University). Results A total of 137 cases were admitted to our hospital within 24 hours after the bullet train crash in Wenzhou.There were 76 males and 61 females,with no significant difference.Of the 137 cases,136 survived and one died after medical treatment.The major injury types included impact injury,crush injury and heavy weight falling injury.Among the 136 survivors,108 cases were with multiple injuries,accounting for 79.4％.The most common injury region of the survivors was the chest,followed by the head and limb.The minimum trauma index (TI) was 5 points and the maximum 27 points.There were 4 cases(3.7％ )with TI ≤9 points,86 (79.6％) with 10-16 points and 18 (16.7％) with ≥ 17 points.Of all,78 cases (72.2％) had ISS score ＜ 16 points and 30 (27.8％) had ≥16 points.The minimum ISS was 3 points and maximum 75 points.There were 40 deaths including the one died after medical treatment,who were all with multiple injuries,with head injury the main cause.ConclusionsThe causes of the bullet train crashes are complicated,with high incidence of multiple injuries.The injury severity is varied,but the overall situation is not serious.Distribution of common injury regions is significantly different between the wounded and the dead.Injury triage,patient transfer and specialist treatment of the wounded should be carried out appropriately during the initial stage of medical rescue based on those injury features after the bullet train crashes.

The objective of study was to investigate the expressions of CD80, CD86 and its ligand CD28 on peripheral lymphocytes in patients with idiopathic thrombocytopenic purpura (ITP), to explore the effect of interleukin 18 (IL-18) and its clinical significance in ITP. The expressions of co-stimulatory molecules (CD80, CD86 and its ligand CD28) on peripheral lymphocytes from 34 ITP patients and 34 normal humans were detected by immunofluorescence and flow cytometry. The IL-18 in the plasma was detected by using enzyme linked immunosorbent assay (ELISA). The results showed that the expressions of CD80 and CD86 on peripheral lymphocytes from ITP patients were higher than that of the normal control (4.21 +/- 2.27%, 7.19 +/- 5.16% vs 2.34 +/- 0.87%, 4.08 +/- 1.96%) (P < 0.01); the concentration of IL-18 in plasma of ITP patients was (538.31 +/- 111.33) pg/ml, but the concentration of IL-18 in plasma of controls was (489.44 +/- 49.07) pg/ml. The level of IL-18 negatively correlated with the platelet counts in peripheral blood (r = -0.395, P < 0.05). It is concluded that the CD28/CD80 and CD28/CD86 costimulatory molecules are overexpressed, when the IL-18 level in ITP patients is obviously higher than that in normal controls. When ITP occurred, and the co-stimulatory molecules CD80 and CD86 are closely associated with ITP, it seems that IL-18 may play an important role in ITP pathogenesis.

Objective To investigate the clinical effects of the stent-laparoscopy approach in treatment of elderly patients with malignant colorectal obstruction.Methods Clinical data of 55 elderly hospitalized patients with colorectal cancer-induced bowel obstruction in Wenzhou Central Hospital from January 2009 to January 2014 were evaluated retrospectively.All patients were treated with expandable metallic stents for remission of bowel obstruction.Patients were divided to laparoscopy surgeryobservation group (n =14) receiving laparoscopic surgery after decompression and the laparotomy surgery-control group (n=41) receiving conventional open colorectal cancer operation.The intraoperative information,postoperative complications and long-term curative effect were compared between the laparoscopy surgery-observation vs laparotomy surgery-control group.Results During laparoscopy surgery period,two patients operated by laparoscopy surgery were converted to laparotomy surgery.Surgical time was significantly longer in the laparoscopy surgery-observation group than in laparotomy surgery-control group[(178 ± 33) min vs.(145 ± 31) min,t =3.384,P =0.001],and bowel function recovery and postoperative hospital stay were significantly shorter in the laparoscopy surgery-observation group than in laparotomy surgery-control group[3.1 ± 0.9) d vs.(4.3 ± 1.3) d and (7.1±1.3) d vs.(12.6±5.7) d,t=3.193 and t=2.911,P=0.002 and P=0.005].Intraoperative blood loss was less in the laparoscopy surgery-observation group than in the laparotomy surgery-control group[(63 ± 29) ml vs (86 ± 37) ml,t =2.11,P =0.04],with no significant differences in postoperative complications between the two groups (0.0 vs 9.76 ％,x2 =1.47,P=0.225).Fifty-five patients were followed up for 2 years.All patients survived in the laparoscopy surgery-observation group,but one patient died from the cerebrovascular accident in the laparotomy surgery-control group.Conclusions The stent-laparoscopy approach to treat colorectal cancer (CRC) patients with acute colorectal obstruction is a safe,effective,recovery quick and minimally invasive option for elderly patients.Emergency surgery may be converted to a limited operation by this method.Laparoscopic radical surgery with one-stage anastomosis is feasible.

OBJECTIVETo investigate the expression pattern of resistin (RSTN) in skeletal muscle tissue and its influence on glycometabolism in rats with traumatic brain injury (TBI).

METHODSSeventy-eight SD rats were randomly divided into traumatic group (n=36), RSTN group (n=36) and sham operation group (n=6). Fluid percussion TBI model was developed in traumatic and RSTN groups and the latter received additional 1 mg RSTN antibody treatment for each rat. At respectively 12 h, 24 h, 72 h, 1 w, 2 w, and 4 w after operation, venous blood was collected and the right hind leg skeletal muscle tissue was sampled. We used real-time PCR to determine mRNA expression of RSTN in skeletal muscles, western blot to determine RSTN protein expression and ELISA to assess serum insulin as well as fasting blood glucose (FBG) levels. Calculation of the quantitative insulin sensitivity check index (Q value) was also conducted. The above mentioned indicators and their correction were statistically analyzed.

RESULTSCompared with sham operation group, the RSTN expression in the skeletal muscle as well as serum insulin and FBG levels revealed significant elevation (P<0.05), and reduced Q value (P<0.05) in traumatic group. Single factor linear correlation analysis showed a significant negative correlation between RSTN expression and Q values (P<0.001) in traumatic group.

CONCLUSIONThe expression of RSTN has been greatly increased in the muscular tissue of TBI rats and it was closely related to the index of glycometabolism. RSTN may play an important role in the process of insulin resistance after TBI.

Contagious ecthyma (also known as orf) is an acute skin zoonosis caused by orf virus (ORFV), which affects sheep, goats and humans. As one of the typical species of the Parapoxvirus genus of the Poxviridae family, orf virus has distinctive and unique characteristics of these species. A range of immuno-modulatory/pathogenesis -related genes acquired by virus that function is to limit (at least transiently) the effectiveness of host immunity during its evolution. This review is aimed to describe the latest progress on the molecular characteristics of ORFV, and upon which we analyzed molecular mechanism of the immune escape designed and a set of strategies developed for ORFV to effective against immune clearance of the host. Known as an essential component in evolutionary system, host is regulated by ORFV for using in population evolution. By the ORFV evolutional immune regulation components and its effect approach, we can understand the viral biological characteristics of ORFV, and it is helpful for us to further study the counter-measures of this disease.

Objective To describe the epidemiological characteristics of cervical spine fracture combined with trauma cervical spinal cord injury (TCSCI) in Guangxi province. Methods A total of 385 patients met the inclusion criteria were enrolled for retrospective investigation. Detailed information included age, sex, marital status, occupation, date of admission, mechanisms of trauma, level of injury, ASIA grade, concomitant injuries, length of hospital stay, complications, and mortality. Results The ratio of Male/Female was 4.4:1. The average age of the patients was 47.9 years, and 88.8％ of the patients were married. 72.9％ of TCSCI occurred between the age of 35-64 years. Farmers accounted for the largest number of patients with TCSCIs, and 63％ of patients with TCSCI were caused by falling. The damage was located at the C3-C5 level, accounting for 63.8％. More than half of the patients with CSCI had brain injury. The most common complication was respiratory infection (54.5％). Among the injury levels, the proportions of ASIA grade A, B, C, and D were 34.8％, 8.5％, 35.5％, and 21％, respectively. During the treatment, 58 patients required cardiopulmonary resuscitation, and 36 patients required mechanical ventilation. The average length of hospital stay was (26.5±21.6) d. Of the 375 patients discharged from the hospital, 51.2％ patients had no improvement in the muscle strength. Conclusions Falling is the main cause of CSCI and men are more likely to be exposed to the injury. Patients with TCSCI have long treatment time and poor treatment results. Additionally, complications during the treatment should not be ignored.

Objective:To explore the clinical efficacy of kidney transplantation(KT)from senile living-related donors aged over 70 years.Methods:Between 2017 and 2019, perioperative and follow-up data from 18 pairs of donors and recipients were retrospectively reviewed.Results:Operations of all 18 pairs of recipients and donors were conducted successfully without serious perioperative complications.No delayed graft function occurred.There was 1 episode(5.6%)of acute rejection.The mean level of serum creatinine(SCr)at Day 3 post-KT and at discharge was(155.7±63.5)and(97.6±28.7)μmol/L.The median follow-up period was 37.5 months.All 18 donors survived with normal renal function.And no proteinuria or kidney donation related hospitalization events occurred.SCr was(84.4±15.0)μmol/L at the last follow-up and there was no statistical significance as compared with SCr level at discharge( P=0.610). No recipient mortality or graft loss occurred.Levels of SCr were(92.1±18.3), (95.5±21.9)and(100.1±21.2)μmol/L at Month 12/24 and the last follow-up.No statistical difference existed in posttransplant SCr level at these follow-up timepoints( P=0.507). Posttransplant proteinuria occurred in 3 recipients(16.7%). In 8 donors, donated kidney glomerular filtration rate(GFR)was lower than 40 ml/(min·1.73m 2). No statistical difference existed in posttransplant SCr level between this group and higher GFR group( P>0.05). Conclusions:After thorough preoperative assessments, satisfactory short-term outcomes may be achieved for KT from living-related donors aged over 70 years.The long-term outcome should be further explored.
