Objectives:To explore the possible mechanisms of ischemic postconditioning on alleviating myocardial ischemia-reperfusion injury, focusing on the inflammatory-thrombus related mechanisms. Methods:Rats were randomly divided into six groups (n=10 each):sham group, ischemia-reperfusion injury group, postconditioning group, SB203580 group, anisomycin+postconditioning (Ani+postconditioning) group and anisomycin (Ani) group. After establising the model of myocardial ischemia reperfusion in rats, the levels of myocardial injury markers troponin I (TnI) and creatine kinase isoenzyme (CK-MB), level of leukocyte-platelet aggregation (PLA) were detected by flow cytometry at different time points, myocardial infarction area was measured by using TTC staining and the level of phosphorylation of p38 MAPK (P-p38 MAPK) was determined by Western blot. Results:Compared with the I/R group, the levels of CK-MB, TnI, the infarct size and the expression of PLA at 60 min and 3 h reperfusion were significantly reduced in the postconditioning group and SB203580 group (P＜0.05). Compared with the postconditioning group, the levels of above parameters were significantly higher in the SB203580 group, Ani+postconditioning group and Ani group (P＜0.05). Compared with the I/R group, the expression of P-p38 MAPK in the postconditioning group, SB203580 group, Ani+postconditioning group was significantly reduced (P＜0.05), while it was significantly upregulated in the Ani group (P＜0.05). Furthermore, compared with the postconditioning group, the expression of P-p38 MAPK in the Ani+postconditioning group and Ani group was significantly upregulated (P＜0.05). SB203580 group presented the similar protection effect as the postconditioning group. Cardioprotective effects of postconditioning was partially reduced in the Ani+postconditioning group. Conclusions:Ischemia postconditioning can reduce the expression of PLA during reperfusion by inhibiting the phosphorylation of p38MAPK, thereby attenuating myocardial ischemia-reperfusion injury.

Objective To observe the effect of postconditioning (PostC) on the expression of platelet-leukocyte aggregation (PLA) during the process of myocardial ischemia and reperfusion in rats, and to explore the mechanisms of ischemic postconditioning (PostC) alleviating myocardial ischemia-reperfusion injury (MIRI). Methods Sixty rats were randomly divided into six groups:sham,reperfusion injury(I/R),postconditioning(PostC),SP600125(inhibition of c-Jun N-terminal kinase,I-JNK),anisomycin and postconditioning(Ani+PostC)and anisomycin(Ani)groups.After constructing the model of myocardial ischemia reperfusion in rats,the levels of myocardial injury markers were detected by using the CK-MB kits and TnI kits. The levels of PLA at different time points were detected by using flow cytometry.The myocardial infarction area were measured by using 2.3.5-Triphenyte-trazoliumchloride(TTC)staining,and the level of phosphorylation of JNK(P-JNK) was determined by using Western blot method. Results (1) The levels of CK-MB, TnI and the infarct size were significantly higher in the I/R group than those in the Sham group(P<0.05).The levels of CK-MB,TnI and the infarct size were significantly lower in the PostC group and I-JNK group than those in the I/R group(P<0.05).Compared with the PostC group,the levels of CK-MB,TnI and the infarct size were significantly higher in the Ani+PostC group and Ani group(P<0.05).(2)Compared with the Sham group,the expression levels of PLA significantly increased in the I/R group at different time points after ischemia (P<0.05). At different time points of MIRI, the expressions of PLA increased gradually in I/R group, Ani+PostC group and Ani group (P<0.05). At the time point of reperfusion for 60 minutes and reperfusion for 3 hours,the expressions of PLA were significantly lower in the PostC group and I-JNK group compared with those of I/R group (P<0.05).Compared with the PostC group,the expressions of PLA were significantly higher in the Ani+PostC group and Ani group (P<0.05). (3) Compared with the Sham group, the expression levels of P-JNK were significantly higher in the I/R group(P<0.05).PostC and I-JNK inhibited the production of P-JNK(P<0.05),while Ani promoted the increase of P-JNK (P<0.05).Compared with the PostC group,the expression levels of P-JNK were significantly higher in the Ani+PostC group and Ani group (P<0.05). Conclusion PostC can reduce the expression of PLA during reperfusion by inhibiting the phosphorylation of JNK,thereby reducing myocardial ischemia-reperfusion injury.

OBJECTIVETo investigate the current situation of drug cost, hospitalization cost and direct medical expense in community health management of hypertensive patients, in order to lay foundation for evaluating whether the community health management in basic public health service has cost-effect in Health Economics.

METHODSA total of 8326 hypertensive patients from 10 survey pilots in 5 provinces were selected by cluster sampling methods, including 3967 patients who took part in community health management for over 1 year as management group and 4359 cases who have never taken part in community health management as control group. The essential information of research objects were collected by questionnaire; and the medical cost information in the last year (from November 2009 to November 2010) were collected retrospectively. The different annual medical treatment cost, hospitalization cost and direct medical expense in the two groups were compared and analyzed.

RESULTSThe average annual drug cost in hypertension was (621.50 ± 1337.78) yuan per patient; while the cost was (616.13 ± 1248.40) yuan in management group and (626.44 ± 1414.30) yuan in control group respectively. The average annual drug cost of hypertensive patients who took medicine therapy was (702.05 ± 1401.79) yuan per person, while the cost in the management group ((688.50 ± 1300.70) yuan) was much lower than it in control group ((714.64 ± 1489.60) yuan). The annual average drug cost in urban was (731.88 ± 1403.31) yuan per person, which was higher than it in rural as (407.44 ± 1171.44) yuan per person. The average hospitalized rate was 12.2% (1014/8326), and the average annual cost among the hospitalized patients was (9264.47 ± 18 088.49) yuan per person; while the cost was (7583.70 ± 13 267.00) yuan in management group, which was lower than it in control group as (11 028.00 ± 21 919.00) yuan. The average annual hospitalized cost in hypertension was (1064.87 ± 6804.83) yuan per person; while the cost was (936.73 ± 5284.90) yuan in management group, which was lower than it in control group as (1181.50 ± 7937.90) yuan. The average annual direct medical expense in hypertension was (2275.08 ± 8225.66) yuan per person; while the expense was (2165.10 ± 6564.60) yuan in management group and (2375.20 ± 9487.60) yuan in control group. The average annual direct medical expense in urban ((2801.06 ± 9428.54) yuan per person) was higher than it in rural ((1254.70 ± 4990.27) yuan per person).

CONCLUSIONThe community health or standardized management of hypertensive patients can reduce the average annual drug cost and hospitalization cost (around 26 yuan and 245 yuan separately); and thereby save the annual direct medical expense per capita in hypertension (around 210 yuan). In the reform and development of national medical health system, we should enhance and promote the standardized community health management of hypertensive patients.

The CatSper channel is known as one of the most important Ca²⁺ channels on the cell membrane of mammalian sperm and plays a key role in the motility, hyperactivation and fertilization function of sperm. The CatSper protein, expressed exclusively in the principal piece of the sperm tail, is composed of CatSper1-4 and 5 auxiliary unitsβ,γ,δ and ε, and has an essential part in the functional and structural domains of Ca²⁺as well as in the spatiotemporal regulation of the P-Tyr protein, sperm hyperactivation, efficient sperm migration in the oviduct, egg penetration, and normal fertility. Recent studies show that functional deficiency of CatSper seriously affects sperm function,and the loss of any one of its 9 subunits may lead to male reproductive dysfunction. This paper outlines recent advances in the studies of the CatSperprotein, focusing on its expression, location, structure, and regulation,as well as itsinfluence on sperm hyperactivation and male reproduction.

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.

OBJECTIVE: To investigate the effect of Rictor on the hematopoiesis of fetal liver by specific knock-out of Rictor in hematopoietic cells of Vav-Cre mice. METHODS: E12.5 0.08ee fetal liver cells from the experimental group Vav-Cre; Rictor embryos and control group Rictor or Rictor embryos were transplanted to recipients respectively to observe the effect of Rictor on reconstitution ability of hematopoietic stem cells. In the meantime, E14.5 0, 10, 20, 40, 60, 80 sorted hematopoietic stem cells from the Vav-Cre; Rictor fetal liver of experimental group and Rictor or Rictor fetal liver of control group were transplanted in to recipients to analyze the numbers of functional hematopoietic stem cells after Rictor was knocked-out. Furthermore, the self-renewal capacity was investigated by secondary transplantation of BM cells from primary recipients that had been successfully repopulated with E12.5 fetal liver-derived cells and by cell cycle analysis. RESULTS: All the recipients receiving E12.5 Rictor or Rictor cells were repopulated (8/8, from 2 independent experiments) with an average chimerism of 77.2%±11.1% at 4 months post-transplantation, which resulted in 57 LT-RU per FL. In comparison, 8 out of 8 recipients receiving Vav-Cre; Rictor cells were repopulated with significantly reduced chimerism (37.0%±16.3%) (P＜0.01), which was equivalent to 8 LT-RU per FL. The limiting dilution transplantation experiment showed that there was one functional hematopoietic stem cell out of 17 sorted SLAM cells in the control group, and one functional hematopoietic stem cell out of 39 sorted SLAM cells in the experimental group. The secondary transplantation experiments showed that 2 out of 4 recipients were reconstructed in the control group after 1 month, and 0 was reconstructed in the experimental group by transplanting 4×10 donor cells respectively. What＇s more, the percentage of S/G/M cells in the experimental group increased when compared with controls. CONCLUSION In the process of fetal liver hematopoiesis, the specifically knocking-out the Rictor in hematopoietic system can lead to defect of reconstitution ability, decrease of the functional hematopoietic stem cell numbers and reduction of self-renewal ability of hematopoietic stem cells.

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.
