Objective : To investigate the prevalence of negative emotions in hospitalized youth patients with type 2 diabetes(T2DM) and its correlation with coping strategies and psychological resilience. Methods : 141 youth T2DM patients who met the research standards were selected. Blood glucose related indicators, blood pressure, body mass index(BMI), diabetes chronic complications screening results and other data were collected. The basic information and disease related information questionnaire, self-rating depression scale(SDS), self-rating anxiety scale(SAS), diabetes distress scale(DDS), medical coping modes questionnaire(MCMQ) and Connor-Davidson resilience scale(CD-RISC) were completed. Results: Among 141 hospitalized youth T2DM patients, 37.6% were combined with depression, 32.6% were combined with anxiety, and 35.5% were combined with diabetic distress(DD). Univariate analysis showed that systolic blood pressure(P<0.01), educational level, and the form of hospitalization expenses(P<0.05) were significantly correlated with depression. Marital status(P<0.01), family residence, blood glucose monitoring methods, and the last fasting blood glucose(P<0.05) were significantly correlated with anxiety. BMI, whether it was first diagnosed or treated(P<0.01), gender, occupation, disease course, weekly blood glucose monitoring frequency, and the presence of chronic complications(P<0.05) were significantly correlated with DD. In multivariate analysis, systolic blood pressure(P<0.01), educational level, and the form of hospitalization expenses were significantly correlated with depression, marital status(P<0.05) was significantly correlated with anxiety; BMI and weekly blood glucose monitoring frequency(P<0.01) were significantly correlated with DD. SDS, SAS, total scores and dimensions of DDS were negatively correlated with the total score and dimensions of CD-RISC(rs=-0.182--0.467, P<0.05 or 0.01), and positively correlated with the yielding coping strategies(rs=0.177-0.271,P<0.05 or 0.01). SAS,total scores and dimensions of DDS were positively correlated with avoiding coping strategies(rs=0.237-0.419,P<0.05 or 0.01). The total and dimensions of CD-RISC were positively correlated with facing coping strategies(rs=0.215-0.349,P<0.05 or 0.01),and negatively correlated with yielding coping strategies(rs=-0.234--0.325,P<0.01). Conclusion More than 30% of hospitalized youth T2DM may experience negative emotions such as depression,anxiety,and DD. The occurrence of negative emotions in such patients may be related to disease management or socio-economic issues such as systolic blood pressure,educational level,hospitalization expenses,marital status,BMI,and frequency of blood glucose monitoring,as well as decreased psychological resilience and negative coping strategies.

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.

To summarize the nursing care experience of a case of idiopathic multicentric Castleman's disease TAFRO syndrome complicated with diffuse alveolar hemorrhage.Key points of nursing:prone position ventilation with high blood risk nursing observation and bleeding prevention;early rehabilitation exercise and the reduction of the lymphedema;the optimization of transitional care to avoid unplanned returns to the ICU.The patient was transferred to the respiratory ward for further treatment after 19 days,and 33 days later,she recovered and was discharged.At 1 month of follow-up after discharge,the patient recovered well.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on perioperative anxiety and postoperative pain in living kidney donors (LKDs).Methods:Seventy-two American Society of Anesthesiologists physical status Ⅰ or Ⅱ LKDs, aged 18-64 yr, with body mass index of 18-28 kg/m 2, undergoing living kidney transplantation, were selected, and divided into 2 groups ( n=36 each) using a random number table method: TEAS group (group T) and sham stimulation group (group S). In group T, TEAS was performed on the forenoon at 1 day before surgery (T 0), at 30 min before anesthesia induction on the morning of the operation day (T 1) and on the forenoon at 1 day after surgery (T 2) at bilateral Neiguan, Taichong and Yintang with a frequency 2-100 Hz, disperse-dense waves and current intensity 6-15 mA, and each TEAS lasted for 30 min.Only electrode patches were applied at the same acupoint and at the same time point, but no stimulation was applied in group S. In T and S groups, brachial venous blood samples were collected before each stimulation for measurement of the plasma 5-hydroxytryptamine (5-HT) concentration.The Hospital Anxiety Depression Scale-Anxiety subscale (HADS-A) scores at T 0, T 1, T 2, on day 3 after surgery (T 3) and before discharge (T 4) in the 2 groups were recorded.The consumption of anesthetics during operation, laryngeal mask airway removal time, requirement for rescue analgesia within 72 h after surgery and the development of postoperative complications were recorded.The LKDs were followed up by telephone at 3 months after surgery (T 5) to record the scores of HADS-A and Leeds Assessment of Neuropathic Symptoms and Sign (LANSS) scale. Results:Compared to group S, the incidence of anxiety was significantly decreased T 1, T 2 and T 3, the incidence of rescue analgesia within 72 h after surgery was decreased, plasma concentration of 5-HT was increased at T 1 and T 2, the incidence of postoperative nausea and vomiting was decreased, and the time to first flatus was shortened in group T ( P<0.05). There was no significant difference in the consumption of anesthetics during operation, laryngeal mask airway removal time, and the incidence of anxiety and neuropathic pain within 3 months after surgery between the 2 groups ( P>0.05). Conclusion:TEAS can relieve early preoperative and postoperative anxiety and alleviate postoperative pain in LKDs.

Objective To investigate the effects of baicalein (Bai) on acute lung injury (ALI) induced by intestinal ischemia/reperfusion (I/R) and its mechanism in mice.Methods Twenty-four male C57BL/6J mice were divided into three groups by random number table:namely sham group,I/R group and Bai+I/R group,with 8 mice in each group.Intestinal I/R induced lung injury model was reproduced by clamping superior mesenteric artery for 90 minutes,followed by reperfusion.Bai (100 mg/kg) was intraperitoneally injected 1 hour before ischemic challenge in the Bai+I/Rgroup.The mice in sham group underwent the similar procedure with I/R group but without vascular occlusion.All mice were sacrificed at 4 hours of reperfusion,and blood was collected from inferior vena cava and lung tissues were harvested.Lung tissues were stained with hematoxylin-eosin (HE),and histological changes were examined under light microscope for pathological score.Lung wet/dry (W/D) ratio was calculated.Lung cell apoptosis was determined by TdT-mediated dUTP nick end labeling (TUNEL) technique.Serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6(IL-6) were determined by enzyme-linked immunosorbent assay (ELISA).The mRNA expressions of TNF-α and IL-6 in lung tissues were determined by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR).The protein expression levels of cytoplasmic inhibitory factor-α of nuclear factor-κB (IκB-α) and nucleus NF-κB were determined by Western Blot.Results Under light microscope,a normal lung tissue structure was shown in the sham group and no evidence of obvious lung injury was found.In the I/R group,the alveolar structure was seriously damaged.The alveolar wall was widened and there was significant interstitial edema and leukocytes infiltration.In the Bai+I/R group,pathological damage was significantly decreased as indicated by reduced lung tissue edema and leukocytes infiltration.Compared with the sham group,the lung pathological scores,W/D ratio and cellular apoptosis in the I/R group were significantly increased.Bothserum TNF-α and IL-6 contents and lung TNF-α and IL-6 mRNA expressions were significantly increased.Furthermore,I/R significantly resulted in a decrease of IκB-α in the cytoplasm and an increase of NF-κB in the nucleus.Notably,Bai treatment significantly attenuated ALI induced by intestinal I/R injury.Compared with the I/R group,the lung pathological scores and W/D ratio in the Bai+I/R group were significantly decreased (lung pathological score:4.59±1.17 vs.6.27±1.34,W/D ratio:3.79±0.28 vs.4.32±0.57),cellular apoptosis was significantly decreased [(4.85 ± 2.47)％ vs.(8.15 ± 2.33)％],both serum TNF-α and IL-6 contents and lung TNF-α and IL-6 mRNA expressions were significantly decreased [serum TNF-α (pg/L):124.18±30.49 vs.167.72 ± 38.65,IL-6 (ng/L):1.65 ± 0.69 vs.2.43 ± 0.57;lung TNF-α mRNA (2-△△Ct:4.75 ± 2.38 vs.7.69 ± 2.32,IL-6 mRNA (2-△△ Ct):16.45 ±4.39 vs.27.69 ± 6.82],additionally,Bai pretreatment significantly increased cytoplasmic IκB-α protein expression (gray value:0.47 ± 0.11 vs.0.27 ± 0.09),while decreased nuclear NF-κB protein expression (gray value:0.57 ± 0.13 vs.1.07 ± 0.14,all P ＜ 0.05).Conclusion Bai could attenuate intestinal I/R injury induced ALI via the inhibition of inflammation and apoptosis.

Spectrophotometric seawater pH measurement system is an urgent need of device due to its quick speed and high precision. Based on spectrophotometric method and flow injection analysis technique, an automated system for pH measurement of seawater was developed by integrating pump and valve flow path, LED light source, flow cell and spectrophotometer. This measurement system effectively avoided bubbles. The indicator of concentration gradient in the seawater sample was used to correct for the pH perturbation caused by the indicator, thus the operation of system was simple and convenient. with this system, only 1. 5 min was needed for a sample measurement with a precision of 0. 0013 pH units and an offset of 0. 0059 pH units. This system could be used for the rapid determination of pH of seawater collected by laboratory or research ship with high precision pH values.

OBJECTIVETo investigate the treatment for tibial exposure wounds.

METHODS39 patients with tibial exposure wounds were divided into three groups according to the exposure location (upper, medium and below). The local muscular flaps were designed to cover the tibial exposure, followed by skin grafts and VSD. VSD was removed one week later.

RESULTSAll the muscular flap and skin graft survived. Mild epidermis erosion happened in 2 cases, which healed spontaneously after dressing. The patients were followed up for 3-6 months with good healing and no walking malfunction.

CONCLUSIONSThe local muscular flap combined with skin graft and VSD is a simple and effective method for tibial exposure wound with short healing time and high successful rate.

Methods NTHi ATCC49247 was investigated in the present study,Pseudomonas aeruginosa (PA)PAO1 was cultured as positive control,at the same time blank control group was set up.The BF of the bacteria were cultured and then collected on day 1,2,3,4,5,6,and 7.The BF formation was detected by crystal violet staining and plate counting and the structure of BF formed by ATCC49247 was observed under SEM on day 3.Results The plate colony counting of biofilm BF by ATCC49247 and PAO1 raised during first 3 d, and then declined to (0.823 6±0.007 5)×107 cfu·mL-1 and (0.942 6±0.019 9)×107cfu·mL-1 respectively on day 7. The differences between two groups were statistically significant on day 3,4,5,and 6 (P<0.05).The differences between different time points in the same bacteria group were statistically significant (P<0.05).The densities of BF formed by ATCC49247 and PAO1 raised during the first 3 d.The absorbances on 570 nm wavelength (A570 )in two groups were 2.717 4±0.017 2 and 2.885 3±0.039 0 ,respectively;and then the A570 values in two groups declined to 0.151 7±0.074 5 and 1.196 9±1.108 5,respectively on day 7;the differences between bacteria groups and blank control were statistically significant (P<0.05 );the differences between two bacteria groups were statistically significant on day 3,4,5,and 6 (P<0.05);the differences between different time points in the same bacteria group were statistically significant (P<0.05).On day 3,the obvious BF formed by ATCC49247 were observed under SEM.Conclusion BF could be formed by NTHi in vitro;crystal violet staining,plate colony counting and SEM could be taken as conventional methods to detect BF.

OBJECTIVETo investigate the clinical application of the vacuum-sealing drainage (VSD) in the prevention of lymph leakage after inguinal lymphadenectomy.

METHODSFrom September 2003 to September 2013, 60 cases who underwent inguinal lymph nodes dissection received VSD (n = 30), or traditional pressure dressing and drainage( control group, n = 30) after operation. The flap blood supply, healing process and incidence rate of lymph leakage were observed.

RESULTSTwenty-eight cases in VSD group were effective. Eleven cases were cured, ten cases were effective, and nine cases were invalid in control group. The cure rate, effective rate and healing period were significantly different between the two groups (P < 0.01).

CONCLUSIONSThe incidence of lymph leakage after inguinal lymphadenectomy can markedly decrease with VSD application. VSD could be an ideal preventive method for post-operative lymph leakage.
