Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

In recent years， the incidence of neurological diseases has been increasing year by year. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of neurological disorders， identify the breakthrough point of integrating TCM with western medicine， and further standardize the clinical diagnosis and treatment of TCM， the China Association of Chinese Medicine organized neurologists in TCM and western medicine to carry out in-depth discussion on the neurological diseases responding specifically to TCM and integrated TCM and western medicine， such as stroke， headache， vertigo， multiple sclerosis， and epilepsy， aiming to formulate a well-recognized and integrated treatment protocol for TCM and western medicine and improve the efficacy of neurological disorders. Furthermore， the treatment suggestions of the corresponding diseases in TCM and western medicine were proposed to provide references for clinical practice and scientific research.

BACKGROUNDStreptococcus pneumoniae (S. pneumoniae) is a major causative agent of severe infections, including sepsis, pneumonia, meningitis, and otitis media, and has become a major public health concern. We report the pneumococcal serotype and sequence type (ST) distribution, and antimicrobial resistance of 39 S. pneumoniae strains from seven hospitals in China.

METHODSBlood/cerebrospinal fluid (CSF) and sputum isolates from patients were analyzed to determine S. pneumoniae serotypes by polymerase chain reaction (PCR) and the Neufeld Quellung reaction, the multilocus sequence types (MLST) by PCR and sequencing, and susceptibility to antimicrobial agents by the VITEK Gram Positive Susceptibility Card.

RESULTSA total of 39 isolates were collected including 21 blood/CSF and 18 sputum isolates. Conventional serotyping by the Quellung reaction required 749 reactions. In contrast, PCR based typing needed only 106 PCR reactions. The most frequent serotypes from the blood/CSF isolates were 14 (38.1%), 19A (14.3%), 23F (9.5%), and 18C (9.5%). In the sputum isolates the most frequent serotypes were 19F (33.3%), 23F (16.7%), 19A (11.1%), and 3 (11.1%). The incidence of penicillin resistance in the blood/CSF and sputum isolates was 66.7% and 55.6%, respectively. Statistical analysis showed that patients = 5 years old had a higher resistance to penicillin when they compared with the patients = 65 years old (P = 0.011). Serotypes 14, 19A and 19F were significantly associated with penicillin resistance (P < 0.001). ST320, ST271, and ST876 isolates showed high resistant rates to several antibiotics including penicillin (P = 0.006). All of the isolates of serotype 19A were resistant to both penicillin and erythromycin, and they were all multi-drug resistant (MDR) isolates.

CONCLUSIONSThe specificity and sensitivity of multiplex-PCR are good, and this method represents a substantial savings of time and money, and can be widely used in the laboratory and clinical practice. Data from this research showed an extremely high prevalence of penicillin resistance and an increasing prevalence of multi-drug resistant (MDR) rate in S. pneumoniae. A distinctive emergence of serotype 19A was observed which was also associated with the increasing prevalence of antimicrobial resistance. Therefore, nationwide surveillance of pneumococcal resistance and serotypes is strongly warranted.

BACKGROUNDStaphylococcus aureus (S. aureus) remains as an important microbial pathogen resulting in community and nosocomial acquired infections with significant morbidity and mortality. Few reports for S. aureus in lower respiratory tract infections (LRTIs) have been documented. The aim of this study was to explore the molecular epidemiology of S. aureus in LRTIs in China.

METHODSA multicenter study of the molecular epidemiology of S. aureus in LRTIs was conducted in 21 hospitals in Beijing, Shanghai and twelve other provinces from November 2007 to February 2009. All the collected S. aureus strains were classified as minimum inhibitory concentration (MIC), mecA gene, virulence genes Panton-Valentine Leukocidin (PVL) and γ-hemolysin (hlg), staphylococcal cassette chromosome mec (SCCmec) type, agr type, and Multilocus Sequence Typing (MLST).

RESULTSTotally, nine methicillin-sensitive S. aureus (MSSA) and 29 methicillin-resistant S. aureus (MRSA) strains were isolated after culture from a total of 2829 sputums or bronchoalveolar lavages. The majority of MRSA strains (22/29) had a MIC value of ≥ 512 µg/ml for cefoxitin. The mecA gene acting as the conservative gene was carried by all MRSA strains. PVL genes were detected in only one S. aureus strain (2.63%, 1/38). The hlg gene was detected in almost the all S. aureus (100% in MSSA and 96.56% in MRSA strains). About 75.86% of MRSA strains carried SCCmec III. Agr type 1 was predominant (78.95%) among the identified three agr types (agr types 1, 2, and 3). Totally, ten sequence type (ST) of S. aureus strains were detected. A new sequence type (ST1445) was found besides confirming ST239 as the major sequence type (60.53%). A dendrogram generated from our own MLST database showed all the bootstrap values ≤ 50%.

CONCLUSIONOur preliminary epidemiology data show SCCmec III, ST239 and agr type 1 of S. aureus as the predominant strains in LRTIs in Mainland of China.

BACKGROUNDEndogenous hydrogen sulfide (H(2)S) plays an important role in hypertension. The aim of this study was to investigate the role of erythrocyte and serum H(2)S in patients with untreated essential hypertension.

METHODSWe recruited 62 patients (age 22 - 74 years) with untreated prehypertension or hypertension, and 64 normotensive subjects (age 18 - 64 years). We assessed the 3-mercaptopyruvate sulphurtransferase (MPST) protein expression in erythrocytes and measured the H(2)S production from erythrocytes and serum H(2)S levels, then analyzed the association of erythrocytic or serum H(2)S content and blood pressure or cardiovascular risk factors (e.g., age, body mass index (BMI) and dyslipidemia). A stepwise regression analysis was used to evaluate the possible relationship of erythrocytic H(2)S in hypertension.

RESULTSIn hypertensive patients, erythrocyte H(2)S production ((111.04 ± 29.20) nmol/min per 10(8) erythrocytes) was higher than that in controls ((78.85 ± 19.38) nmol/min per 10(8) erythrocytes), and serum H(2)S was also higher. The erythrocytic H(2)S production was associated with increased systolic blood pressure (sBP), diastolic blood pressure (dBP), age, BMI, level of C-reactive protein (CRP), as well as triglycerides (TG) and high density lipoprotein cholesterol (HDL-C). Serum H(2)S was not associated with age or CRP. Stepwise regression analysis showed that erythrocytic H(2)S production was correlated with sBP, TG, HDL-C, low density lipoprotein cholesterol (LDL-C) and blood urea nitrogen (BUN) and serum H(2)S was correlated with dBP and TG. Results of receiver-operating characteristic curve analysis suggested that erythrocytic H(2)S production was a more sensitive predictor of hypertension development than serum H(2)S.

CONCLUSIONErythrocytic or serum H(2)S production is sensitive predictor of hypertension.

Objective To study the reliability of transcutaneous bilirubin (TCB) of different parts of neonates as predictive alarm of serum bilirubin ( SB ). Methods 132 cases of full-term neonates in Handan Central Hospital from May to July 2010 were divided into spontaneous delivery group and cesarean section group by random number. A KJ8000 transcutaneous bilirubinmeter was used to test their TCB at forehead, chest and abdomen on the fourth day after birth. The neonates were measured SB once TCB readings were more than 12.9 mg/dl. TCB of different parts and SB of the two groups were compared. Results The spontaneous delivery group had 17 cases of the. Neonates whose TCB readings were more than 12.9 mg/dl while the cesarean section group had 21 cases. TCB and SB of the same part by the same method showed no statistical significance between the two groups (t =0. 71, 2. 0, 1.25, 1. 0, 1.5;P ＞0. 05). TCB readings of chest were of no significant difference as compared with SB of the same group ( t =1. 72, 1. 33 ; P ＞ 0. 05 ). Conclusions SB of the spontaneous delivery group and the cesarean section group was of no significant difference. TCB reading of chest was closer to SB.

BACKGROUNDAcinetobacter baumanii (A. baumanii ) remains an important microbial pathogen resulting in nosocomial acquired infections with significant morbidity and mortality. The mechanism by which nosocomial bacteria, like A. baumanii, attain multidrug resistance to antibiotics is of considerable interest. The aim in this study was to investigate the spread status of antibiotic resistance genes, such as multiple β-lactamase genes and aminoglycoside-modifying enzyme genes, from A. baumanii strains isolated from patients with lower respiratory tract infections (LRTIs).

METHODSTwo thousand six hundred and ninety-eight sputum or the bronchoalveolar lavage samples from inpatients with LRTIs were collected in 21 hospitals in the mainland of China from November 2007 to February 2009. All samples were routinely inoculated. The isolated bacterial strains and their susceptibility were analyzed via VITEK-2 expert system. Several kinds of antibiotic resistant genes were further differentiated via polymerase chain reaction and sequencing methods.

RESULTSTotally, 39 A. baumanii strains were isolated from 2698 sputum or bronchoalveolar lavage samples. There was not only a high resistant rate of the isolated A. baumanii strains to ampicillin and first- and second-generation cephalosporins (94.87%, 100% and 97.44%, respectively), but also to the third-generation cephalosporins (ceftriaxone at 92.31%, ceftazidine at 51.28%) and imipenem (43.59%) as well. The lowest antibiotic resistance rate of 20.51% was found to amikacin. The OXA-23 gene was identified in 17 strains of A. baumanii, and the AmpC gene in 23 strains. The TEM-1 gene was carried in 15 strains. PER-1 and SHV-2 genes were detected in two different strains. Aminoglycoside-modifying enzyme gene aac-3-Ia was found in 23 strains, and the aac-6'-Ib gene in 19 strains. aac-3-Ia and aac-6'-Ib genes hibernated in three A. baumanii strains that showed no drug-resistant phenotype.

CONCLUSIONSA. baumanii can carry multiple drug-resistant genes at the same time and result in multi-drug resistance. Aminoglycoside-modifying enzyme genes could be hibernating in aminoglycoside sensitive strains without expressing their phenotype.

BACKGROUNDBacterial vaginosis (BV) is one of the most common infectious diseases among sexually active women and is associated with the increased acquisition of a variety of sexually transmitted diseases. This study aimed to compare the efficacy of a non-antibiotic sucrose gel against an antibiotic metronidazole gel for the treatment of BV.

METHODSA randomized, double-blinded, multi-center, parallel-group, placebo-controlled phase III clinical trial was conducted at eight hospitals in China. A total of 560 subjects with clinically diagnosed BV were randomly assigned into three groups for vaginally receiving sucrose, metronidazole, and placebo gels, respectively, twice daily for five consecutive days. The efficacy of therapeutic cure, defined as an achievement of both microbiologic cure (a Nugent score of 3 or less) and clinical cure (a resolution of the clinical findings from the baseline visit), was evaluated at the 1st and 2nd test-of-cure (TOC) visits at 7-10 and 21-35 days after the start of treatment, respectively.

RESULTSTherapeutic cure rates for sucrose, metronidazole, and placebo gel groups were 83.13%, 71.30% and 0.92%, at the 1st TOC, and 61.04%, 66.67% and 7.34%, at the 2nd TOC, respectively. While there was no significant difference between the sucrose and metronidazole gel groups at the 2nd TOC (P = 0.305), and sucrose gel was more effective than metronidazole gel at the 1st TOC (P = 0.009).

CONCLUSIONThese findings suggest that sucrose gel restores normal vaginal flora more rapidly than metronidazole gel and can be used as a novel treatment for BV.
