Acute traumatic coagulopathy (ATC) attacks suddenly with a rapid progress and has an extremely highly mortality.Of late years more and more relative studies have made a great progress on the pathogenesis,diagnosis and treatment of ATC.However,there are currently no medical guidelines for ATC.There are still some problems such as nonstandard treatment,outdated concept and so on in clinic.Based on the latest research progresses home and abroad,this paper expounds emphatically the first-aid and treatment of ATC in order to bring helps to the clinical doctors.

Around the world, the supply of health services faces challenges, especially in developing nations that suffer from inadequate infrastructure and aging equipment, frequent shortages of medicine and supplies, and low capacity and efficiency of primary health care. At present, more and more governments adopt public-private partner-ships to achieve public policy goals. Among those, Brazil, South Africa, and India have made greater achievements in changing the roles of local government, increasing the supply of primary health care and health care quality, pro-moting health care equality, meeting the needs of multi-level medical services, and promoting health capabilities by using public-private partnerships. This paper provides an overview of public-private partnership practices in the three countries, discusses their reform experiences, and concludes with implications which may be helpful for promoting and scaling up PPP in primary health care in China.

Objective To explore the effect of postural reduction and balloon dilation on the correction of vertebral height following balloon percutaneous kyphoplasty (PKP) for osteoporotic vertebral coinpressive fracture (OVCF).Methods From June 2012 to December 2013,47 OVCF patients involving 57 fractured thoracolumbar vertebrae with intact posterior wall underwent PKP.In all patients postural reduction was performed under general anesthesia.The percentages of vertebral height loss before and after balloon dilation were compared.The curative effects were evaluated by comparing preoperative and postoperative visual analogue scale(VAS) scores and cobb angles.Results Compared with preoperation,the vertebral heights of anterior and middle columns were significantly improved after postural reduction,balloon dilation and PKP (P ＜ 0.05),but there was no significant improvement before and after balloon dilation (P ＞0.05).The postoperative average cobb angle (22.8°± 8.1°) was significantly decreased compared with the preoperative one (22.8° ± 8.1°) (P ＜ 0.05).The VAS scores at preoperation,one day postoperation and the final follow-up were respectively 8.5 ± 0.4,3.4 ± 0.2 and 3.1 ± 0.3.The postoperative ones were significantly lower than the preoperative one (F =7.518,P =0.006).Conclusions In PKP,postural reduction under general anesthesia plays an important role,but balloon dilation may exert an insignificant effect on restoration of vertebral height.

ObjectiveTo investigate whether the effects of trait anxiety on decision making under risk　and decision making under ambiguity are the same.Methods 185 subjects were grouped into high trait anxiety　(HTA),medium trait anxiety (MTA) and low trait anxiety (LTA) groups based on their trait anxiety scores.All　subjects were assessed by the Iowa Gambling Task (IGT),the Game of Dice Task (GDT) and the Wisconsin Card　Sorting Task (WCST).ResultsHTA and LTA subjects compared to MTA subjects were impaired in decision　making under ambiguity( MTA:2.08 ± 18.51 ; HTA:5.62 ± 20.35 ; LTA:5.94 ± 10.96,F =3.86,P =0.023 ),the relation between trait anxiety and IGT performance resembled the curved shape of an inverted U.Performances　of the three groups had no differences on decision making under risk (MTA:4.55 ± 10.17; HTA:4.00 ± 9.75;LTA:4.33 ± 11.20,F=0.03,P=0.968 ),and had no differences on executive functions and feedback processing.ConclusionTrait anxiety has effect on decision making under ambiguity,but not decision making under risk.The results provide support for the idea that decision making under ambiguity and decision making under risk are　different processes,moreover,support and extend the view that emotion has an impact on cognitive function.

Objective To search for the most appropriate subzero nonfreezing temperature,and explore the effect of subzero nonfreezing preservation of rat kidney by comparing with the kidney preservation with conventional temperature (4 ℃,0 ℃) and freezing temperature (-4 ℃).Method The thermocouple probeand the temperature data logging device were used to detect the temperature decreasing curves in different parts of the rat kidney and determine the freezing point of the kidney.The perfused kidneys in rats were removed and put into the sterile tubes containing 2.5 mL hypertonic citrate adenine.Following 6 group were set up:-0.8 ℃ group (subzero nonfreezing),-0.5 ℃group (subzero nonfreezing),0 ℃ group (zero nonfreezing),-4 ℃ group (control group),-1 ℃group(subzero freezing)、-4 ℃ group (subzero freezing).After the cryopreservation for 24 and 48 h,the preservative fluid was harvested for measurement of the contents of LDH and AST,and the paraffin sections from the upper pole of the kidney were made for observation of the pathological changes and apoptosis.Result The freezing temperature of kidney was-1℃ and the most appropriate subzero nonfreezing temperature for preserving the rat kidney was-0.8 ℃.Subzero nonfreezing significantly inhibited the basal metabolic rate of the histiocytes,reduced the contents of LDH and AST released due to the membrane damage,and decreased the apoptosis rate [48 h:-0.8 ℃ (40.1 ± 7.0) ％ vs.4 ℃ (47.1 ± 7.6) ％].Under the light microscope after preservation for 48 h,the pathological changes in-0.8 ℃ group were less than in 4 ℃ group.Conclusion Compared with the organ preservation in conventional temperature (0 ℃-4 ℃),the subzero nonfreezing (-0.8 ℃) can further inhibit the basal metabolic rate of histocytes obviously,reduce its energy consumption,and lower the apoptosis caused by low temperature damage.

Abstract: Objective　To understand the contamination status, drug resistance, virulence gene carrying status, and molecular typing characteristics of Vibrio parahaemolyticus (VP) in aquatic products sold in Nanchang City. Methods　A total of 170 commercial crayfishes, freshwater fish frogs and related smears samples were collected from various farmers' markets in Nanchang from March to September 2021. The strains of V. parahaemolyticus were detected and isolated from the samples. Antibiotic resistance test, virulence gene test, and pulsed-field gel electrophoresis (PFGE) molecular typing analysis were carried out. Results　Among the collected samples, V.parahaemolyticus was only isolated from crayfish and crayfish smear samples, with a total of 35 strains of VP isolated. No V.parahaemolyticus strain was isolated from other freshwater fish, frogs, and their smear samples. Among the 17 common antibiotics tested, only two trains showed resistance to ampicillin, and one strain to streptomycin, , and all were sensitive to other antibiotics; all 35 strains of V. parahaemolyticus carried the gene, but only one strain carried the heat-resistant related hemolysin gene trh, and no direct heat-resistant hemolysin gene tdh positive strain was found; PFGE pattern clustering showed that there was no strain with the same PFGE pattern, and there was no obvious dominant cluster among these strains, and their genetic relationship was relatively distant. Conclusions　The contamination of V. parahaemolyticus in small and medium-sized crayfish sold in the market in Nanchang City is relatively serious. The V. parahaemolyticus isolates in these polluted crayfish generally do not carry key virulence genes such as tdh, are sensitive to common antibiotics, and only have low-level resistance to ampicillin and streptomycin. PFGE pattern clustering showed that V. parahaemolyticus does not have no obvious dominant cluster, and these strains have rich genetic diversity, indicating that they may have different sources.

Objective To investigate the existence of neglect and explore the relationship between spacial attentional deficits and hemisphere in patients with schizophrenia. Methods 51 schizophrenic patients and 55 healthy controls were measured with line bisection test and number bisection test、 Results In the Line Bisection Test,shcizophrenic patients group showed a negative deviation, in which the 2cm line( -0.03 ± 0. 74 )% and mean ( - 0. 02 ± 0. 03 ) % deviation rates were more significantly leftward than that of the normals ( ( 0. 00 ±0.02 ) %, ( - 0.00 ± - 0.01 ) %, P ＜ 0. 05 ) respectively. The mean deviation rates of the patients (P ＜ 0. 01 ) and control groups (P ＜ 0. 05 ) were also significantly leftward compared with zero value. In the number bisection test,schizophrenic patients group showed a negative deviation and a significant leftward bias on the interval 5 ( - 0.07 ±0.18)% ,7( -0.08 ±0.22)% and 9( -0.09 ±0.28)% ) than that of the normals(( -0.01 ±0.05)% ,(0.01± 0. 08 ) % and (0.00 ± 0.14 ) %, P ＜ 0.05 respectively). Conclusion Schizophrenic patients have a right-neglect, suggesting that spacial attentional deficits exist, and it may be related to the left cerebral hemisphere dysfunction.

Objective To investigate decision making under risk in patients with antisocial personality disorder(ASPD).Methods The game of dice task (GDT) was a commonly used measure of decision making under risk.31 ASPD patients and 33 healthy controls (HC) were investigated by GDT with explicit probability.Results ASPD patients performed poorly in the entire task.ASPD selected more risky options (ASPD:10.06 ±5.26,HC:5.42 ± 3.29,t =4.201,P ＜ 0.01) compared with healthy controls.The most frequent choice made by ASPD patients was two numbers.Accordingly,the most frequent choice made by HC group was three numbers(one number:the median of ASPD patients was 1 (1-8),the median of HC was 1 (0-2.5),Z =-2.295,P =0.022) ;three numbers:ASPD:4.77 ±4.23;HC:6.79 ±3.43; t=-2.100,P=0.04;four numbers:ASPD:3.06 ±3.53;HC:5.82 ± 3.41 ; t =3.176,P=0.002).The frequency of choosing the risky options had correlation with the rate of using negative feedback(r =-0.613,P ＜ 0.01),impulsiveness (r =0.481,P =0.006) and the results of Stroop test (r =0.566,P ＜ 0.01).Conclusion Main results reveal that patients with ASPD make risky decisions significantly more often than the HC.Moreover,they show lack of capacity to advantageously utilize feedback,and correlation with executive function,impulsiveness,and negative feedback.

OBJECTIVETo investigate the effect of paraquat (PQ) on reactive oxygen species (ROS) and neutrophil apoptosis and its possible signal transduction pathways.

METHODSCultured neutrophils were treated with different concentrations of PQ for 6-24 h. The apoptosis rate of neutrophils and ROS content were determined by flow cytometry. The exoressions of nuclear factor kappa B (NF-κB) and Caspase 3 were detected by Western blot. These parameters were checked again after NF-κB and Caspase 3 antagonist were applied.

RESULTSPQ could boost ROS generation and depress neutrophil apoptosis significantly. At the same time PQ could enhance the expression of NF-κB and inhibit the expression of Caspase 3. These effects could be reversed by ROS inhibitor diphenyleneiodonium (DPI) and NF-κB inhibitor pyrrolidinedithiocarbamate (PDTC).

CONCLUSIONPQ is a potent inducer of ROS and can inhibit neutrophil apoptosis by activating NF-κB and surpressing Caspase 3 activity.

Literatures on pain intervention with transcutaneous electrical acupoint stimulation (TEAS) were collected by searching the databases both in Chinese and English, and summarized to understand the research progress of TEAS effects on pain mediators in recent years. This will provide a more objective and scientific theoretical basis for clinical practice of TEAS to treat pain syndrome, thus promoting the clinical application of TEAS. Our literature analysis indicated that TEAS effectively regulated the release levels of various pain factors such as prostaglandin, 5-hydroxytryptamine, interleukins, substance P and tumor necrosis factor-α to achieve the analgesic effects by affecting the conduction pathways. TEAS is a safe, non-invasive and effective treatment for pain syndrome. However, further research is necessary due to the lack of rigor of the current clinical trial design.
