Objective To investigate the epidemiological characteristics of multiple-injuries of bone and joint in the belief that a better knowledge of such injuries may help their prevention and treatment. Methods A retrospective study was done on the data of 346 patients with multiple-injuries of bone and joint who had been ad- mitted to our department from January 2001 to December 2004. On the basis of CAI's classification, the following data were statistically analyzed: gender, age, cause of injury, injured part, number of injured parts, associated injuries and mortality. Results Of the 346 injured patients, there were 278 males and 68 females, with an av- erage age of 32.8 years (9months to 89 years). Two hundred and twenty-six cases resulted from traffic accidents, 65 from crush by a heavy object, and 52 from falling. There were 159 fractures of shaft of tibia and fibula, 96 fractures of femoral shaft, 87 fractures of shaft of ulna and radius, 58 fractures of ankle and foot, 57 chest injuries, 50 knee injuries, 50 hip injuries, 49 injuries at the pelvis region, 46 wrist and hand injuries, 36 injuries of shoulder, 36 skull fractures, 33 fractures of humeral shaft, 23 spinal fractures, and 17 elbow injuries. Two hundred and forty-two patients had two parts injured, 83 had three parts, 20 had four parts, and one had six parts. The average number of injured parts was 2.3. Two hundred and five patients suffered from close injuries, and 141 from open ones. The associated injuries included skull and brain injury in 51 cases, chest injury in 23, abdomen injury in five, urine system injury in three, nerve and vessel injury in 21, shock in 78, and fat embolism in six. Five patients died. Conclusions Male young people tend to be the majority of victims of multiple-injuries of bone and joint. Traffic accidents result in most of such injuries. Since multiple-injuries mostly involve lower limbs, they are easy to diagnose while the associated close injuries involving brain, chest, abdomen and pelvic are likely to be overlooked or misdiagnosed. Strengthening safety education and technical training of first aid is important to im- provement of treatment and to decrease of disability rate and mortality.

OBJECTIVETo study the mutual influences between intra-abdominal hypertension (IAH) and intestinal dysfunction, and to observe the efficacy of Tongfu Granule (TFG) in treating IAH of patients with multiorgan dysfunction syndrome (MODS).

METHODSAdopting randomized, double-blinded, controlled method, 60 MODS patients hospitalized in authors' ICU wards from August 2007 to January 2008 were equally assigned to two groups: A and B, that is, the TFG group and the placebo group, all were treated by conventional treatment but different in the administration of TFG and placebo, respectively 1 bag, three times per day, for 7 days via oral intake or gastric infusion. On the 1st, 3rd and 7th day or before death, patients were monitored in terms of symptoms (abdominal distention, defecation, borborygmus, abdominal circumference, intra-abdominal pressure, and occult blood in stool), gastrointestinal function score, APACHE II score, and 28-day outcome. The blind outcome was shown up by specified tester by the end of the observation of 60 cases, A is the TFG group, B is the placebo group.

RESULTSAs compared with the placebo group, intestinal peristalsis and borborygmus were increased, the intra-abdominal pressure and circumference were decreased in the TFG group significantly, which could reduce the possibility of gastrointestinal hemorrhage. Moreover, the gastrointestinal function score and APACHE II score were improved and the 28-day mortality was reduced to a certain degree in the TFG group.

CONCLUSIONTFG could promote the recovering of gastrointestinal function and relieve the heightened intra-abdominal pressure in patients with MODS so as to improve patients' prognosis to some extents.

Objective To explore the risk factors of the occurence and 28-day death of acute respiratory distress syndrome (ARDS) in intensive care unit (ICU). Methods A prospective multicentral cohort study was conducted. The patients from five ICUs of grade A tertiary hospitals in Beijing from July 2009 to March 2014, including sepsis,septic shock,trauma,pneumonia,aspiration,massive blood transfusion,bacteremia and pulmonary contusion,were enrolled. Researchers in each center reported the records with uniform tables,which included demographic,systemic conditions,the primary disease,and the severity within 24 hours,past history and so on. According to the admission diagnosis in ICU,these patients were divided into ARDS group and other severe disease control group. The risk factors of occurence and prognosis of ARDS were analyzed by univariate analysis,multivariate logistic regression and multivariate COX regression analysis. Kaplan-Meier method was applied to draw the 28-day survival curves of the two groups. Results There were 343 critical patients included in this prospective multicenter cohort study,of which 163 patients who developed ARDS were considered as ARDS group(2 case lost to follow-up, and 49 died)and 180 patients who did not developed ARDS regarded as severe control group(1 case lost to follow-up, and 34 died). The 28-day mortality of ARDS group was significantly higher than that of severe control group〔30.43%(49/161)vs. 18.99%(34/179),χ2=6.013,P=0.014〕. Multivariate logistic analysis showed that aspiration〔odds ratio(OR)=6.390,95% confidence interval(95%CI)=2.046-19.953,P=0.001〕,history of alcohol (OR=4.854,95%CI=1.730-13.617,P=0.003),sepsis(OR=2.859,95%CI=1.507-5.425,P=0.001), pneumonia(OR=2.822,95%CI=1.640-4.855,P<0.001),acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score(OR=1.050,95%CI=1.007-1.094,P=0.022)were significantly associated with increased risk of ARDS occurence. When respiratory rate>30 beats/min(OR=3.305,95%CI=1.910-5.721,P<0.001), heart rate>100 beats/min(OR=2.101,95%CI=1.048-4.213,P=0.037)happened in critically ill patients, it highly suggested ARDS would happen. The proportion of the patients whose serum creatinine>176.8 μmol/L in ARDS group was lower than that in control group(OR=0.387,95%CI=0.205-0.733,P=0.004). Multivariate COX regression analysis showed that old age and septic shock were significantly associated with the increased risk of in 28-day death of ARDS〔advanced age:hazard ratio(HR)=1.040,95%CI=1.018-1.064,P<0.001;septic shock:HR=3.209,95%CI=1.676-6.146,P<0.001〕. Kaplan-Meier showed that the survival patients in ARDS group was significantly lower than those in severe control group(χ2=7.032,P=0.008). Conclusions Among critical ill patients,aspiration,history of alcohol,sepsis,pneumonia,increased APACHEⅡ score were the risk factors of ARDS development. Respiratory rate>30 beats/min and heart rate>100 beats/min could predict the occurrence of ARDS in critical patients. Old age and septic shock were the risk factors of 28-day death of ARDS.

OBJECTIVESTo screen and clone the genes encoding hepatocellular carcinoma associated tumor antigens.

METHODSA hepatocellular carcinoma cDNA express library was constructed with ZAP vector and analyzed by serological analysis of recombinant cDNA expression library (SEREX) with sera from autologous and allogenous patients. Monoclonalized positive phage clones were converted into pBK-CMV phagemid forms by in vivo excision. The cDNA inserts were determined by restriction endonuclease digestion with EcoR I and Xho I. The cDNA inserts were sequenced and analyzed with bioinformatics. LIMS1 insert was cut from the clone HCL5-70 and constructed into pQE 31 express vector. The recombinant LIMS1 was expressed in M15 and analyzed with SDS-PAGE and Western blot.

RESULTSFourteen genes were cloned from autologous screening and eleven genes were obtained with allogeneous analysis. One gene, kinectin, was identified in both autologous and allogeneous screening. Eight of the total twenty-four genes were unknown for their functions; the other sixteen genes can be classified into eight groups according to their established or putative function. Recombinant LIMS1 was expressed in M15.

CONCLUSIONThe identification of hepatocellular carcinoma associated tumor antigens provides potential targets for immunotherapy of hepatocellular carcinoma patients and will help in the understanding of the carcinogenesis of hepatocellular carcinoma.

Objective:To explore the clinical characteristics and genetic variants in three children with late-onset Multiple acyl-Coenzyme A dehydrogenase deficiency (MADD type Ⅲ).Methods:Clinical data of three children diagnosed with late-onset MADD at the Children′s Hospital Affiliated to Zhengzhou University between March 2020 and March 2022 were retrospectively analyzed. All children were subjected to whole exome sequencing (WES), and candidate variants were verified by Sanger sequencing. All children had received improved metabolic therapy and followed up for 1 ~ 3 years.Results:The children had included 2 males and 1 female, and aged from 2 months to 11 years and 7 months. Child 1 had intermittent vomiting, child 2 had weakness in lower limbs, while child 3 had no symptom except abnormal neonatal screening. Tandem mass spectrometry of the three children showed elevation of multiple acylcarnitines with short, medium and long chains. Children 1 and 2 showed increased glutaric acid and multiple dicarboxylic acids by urine Gas chromatography-mass spectrometry (GC-MS) analysis. All children were found to harbor compound heterozygous variants of the ETFDH gene, including a paternal c. 1211T>C (p.M404T) and a maternal c. 488-22T>G variant in child 1, a paternal c. 1717C>T (p.Q573X) and a maternal c. 250G>A (p.A84T) variant in child 2, and a paternal c. 1285+ 1G>A and maternal c. 629A>G (p.S210N) variant in child 3. As for the treatment, high-dose vitamin B2, levocarnitine and coenzyme Q 10 were given to improve the metabolism, in addition with a low fat, hypoproteinic and high carbohydrate diet. All children showed a stable condition with normal growth and development during the follow-up. Conclusion:The compound heterozygous variants of the ETFDH gene probably underlay the muscle weakness, remittent vomiting, elevated short, medium, and long chain acylcarnitine, as well as elevated glutaric acid and various dicarboxylic acids in the three children with type Ⅲ MADD.

OBJECTIVE: To evaluate clinical efficacy of arthroscopic with platelet-rich plasma (PRP) in treating meniscus injury. METHODS: From January 2015 to December 2019, clinical control study on repair meniscus injury by arthroscopic with PRP between arthroscopic were searched by PubMed, Science Direct, Cochrane library, Chinese Journal Full-text Database, Wanfang and VIP database. Literature screening, data extraction and quality evaluation according to inclusion and exclusion criteria. Visual analogue scale(VAS) of knee joint and Lysholm score at 1, 6 and 12 months after opertaion between two groups were compared, and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) at 3, 6 and 12 months after opertaion between twogroups were also compared. RESULTS: Totally 9 literatures and 329 patients with meniscal injuries were screened, include 146 patients treated by arthroscopic with PRP and 183 patients treated by arthroscopic. There were no statistical differences in VAS between two groups at 1, 6 and 12 months after opertaion. There were differences in Lysholm score at 1 and 6 months after operation between two groups [ CONCLUSION Arthroscopic with PRP for repair meniscus injury has short term efficacy of knee function and delay arthritis, while has similar effect in long term clinical efficacy and relieve pain.

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.
