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.

OBJECTIVE To observe the clinical efficacy and safety of albumin-bound paclitaxel combined with nedaplatin inductive chemotherapy followed by concurrent radiochemotherapy in the treatment of loco-regionally advanced nasopharyngeal carcinoma. METHODS The clinical data of 45 patients （observation group ） with loco-regionally advanced nasopharyngeal carcinoma（Ⅲ/Ⅳa stage ）who received albumin-bound paclitaxel combined with nedaplatin inductive chemotherapy in our hospital from August 2017 to July 2018 were retrospectively analyzed. Propensity score was used to match 45 patients（control group ）with loco-regionally advanced nasopharyngeal carcinoma who received docetaxel combined with cisplatin and fluorouracil inductive chemotherapy. After inductive chemotherapy ，both groups received intensity-modulated radiochemotherapy （IMRT）；observation group was additionally given concurrent nedaplatin chemotherapy ，and control groups was given concurrent cisplatin chemotherapy. Clinical efficacy and the incidence of ADR were compared between 2 groups. RESULTS All patients completed treatment and 3-year follow-up. After inductive chemotherapy and 1，3 months after concurrent radiochemotherapy ，there was no statistical significance in short-term response between 2 groups（P＞0.05）. There was no significantly difference in 3-years local control rate and 3-years free from distant metastasis between 2 groups（P＞0.05）. The incidences of leucopenia （grade 3 or above ）in the observation group were significantly lower than those in the control group ，and the incidence of peripheral neuropathy in observation group was higher than that in control group （P＜0.05）. The incidences of thrombocytopenia （grade 2 or above ），rash and vomiting （grade 2 or above ）in the observation group were lower than those in the control group ，but the difference was not statistically significant （P＞0.05）. There was no significant difference in the incidence of other ADR between 2 groups（P＞0.05）. CONCLUSIONS Albumin-bound paclitaxel combined with nedaplatin inductive chemotherapy followed by concurrent chemoradiotherapy in the treatment of loco-regionally advanced nasopharyngeal carcinoma is effective and tolerable ．

Objective To analyze the efficacy of no-touch technique and traditional technique in drawing great saphenous vein during coronary artery bypass grafting. Methods We searched the literatures on no-touch technique versus traditional technique in drawing great saphenous vein during coronary artery bypass grafting in PubMed, Cochrane Library, Chinese Journal Full-text Database, Wanfang database between January 1997 and November 2017. Jadad scale was used for quality verification. RevMan 5.0 was used for analysis. Results Six studies were included. Jadad scale for both 6 randomized controlled trials was 5 points. Meta-analysis showed that there was no statistical difference in postoperative mortality between the two groups with RR=0.68 and 95%CI 0.11 to 4.11(P=0.67). There was no statistical difference in leg wounds with RR=1.46 and 95%CI 0.23 to 9.16 (P=0.68). There was no statistical difference in short-term cardiogenic death with RR=0.33, 95%CI 0.10 to 1.03 ( P=0.06). The no-touch group’s long-term cardiogenic death was significantly lower than the traditional group withRR=0.36, 95%CI 0.16 to 0.79(P=0.01). Postoperative no-touch group’s short-term patency rate was significantly better than that of the traditional group with MD=3.08 and 95%CI 1.58 to 5.99 (P<0.01). The long-term patency rate in the no-touch group was also higher than that of the traditional group withMD=3.08 and 95%CI 1.58 to 5.99 (P<0.01). Conclusion Compared with the traditional group, the no-touch group increases postoperative long-term survival rate, short-term and long-term patency rate.

Objective To investigate the relationship between the serum level of vancomycin and its clinical efficacy as well as adverse reactions in adult patient so as to provide recommendations for clinical management. Methods An open observational research was performed from 1st July 2013 to 31st December 2017 in Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, which recruited the adult patients who were infected with Gram positive (G+) bacteria and treated with vancomycin. The initial dose was decided by the patient's creatinine clearance rate, and the treating dose was directed by the serum drug concentration and the patient's clinical response. By recording the associated clinical information (pathogen eradication, blood test results, adverse reactions, etc.), the clinical outcome and adverse reactions for vancomycin to treat G+bacterial infections were analyzed. Results Eighty-nine cases who meet research standards were finally recruited, with 67.42% of male patients, and an average age of (50.5±17.9) years. The most common type of infection was bloodstream infection (61.80%), followed by low respiratory infection (17.98%). Infections caused by Staphylococcus aureus accounted for 39.33%. The bacterial eradication rate was 89.89% (80/89) and the total effective rate was 77.53% (69/89). The effective rate was 80.30% (53/66) with minimum inhibitory concentration (MIC) < 2 mg/L vs. 69.57% (16/23) with MIC ≥ 2 mg/L, the difference was not statistically significant (χ2= 1.129, P = 0.288). The effective rate was 72.92% (35/48) with trough levels <10 mg/L vs. 82.93% (34/41) with trough levels ≥ 10 mg/L, the difference was not statistically significant (χ2= 1.272, P = 0.259). There were 4 cases of vancomycin associated nephrotoxicity, the incidence of nephrotoxicity was 4.49%, and the vancomycin serum trough levels were 17.22-28.53 mg/L. There were 33 cases of liver dysfunction, and elevated γ-glutamine transferase, alkaline phosphatase and aspartate aminotransferase were most common. There were 2 cases of neutropenia and 2 patients appeared rash during vancomycin period. Conclusions Treatment outcomes were similar regardless of vancomycin MIC and serum trough level. The incidence of vancomycin associated nephrotoxicity rises apparently when serum trough level is over 15 mg/L. Clinical Trial Registry Chinese Clinical Trail Registry, ChiCTR-OPC-16007920.

Objective To explore the correlation between psychological health service demand and loneliness and anxiety depression in rural left-behind women.Methods 260 left-behind wo nen in Hebei province were surveyed by psychological health service demand scale,UCLA loneliness scale,trait anxiety scale and the center for epidemiologic studies depression scale (CES-D).Results There were statistically significant differences between the only child and non-only child left-behind women in mental health service demand ((131.72±13.91) vs (122.94±14.76)),loneliness ((52.94±5.65) vs (49.864±5.90)) and anxiety ((50.97±6.38) vs (47.16±4.80)) (t=3.313,2.899,4.151,P＜0.01).The mental health service demand,loneliness,anxiety and depression of left-behind women were different in the age of marriage (F=6.196,9.441,5.257,4.221,all P＜0.01),husband go out time (F=2.761,27.020,4.550,2.830,all P＜0.05) and degree of farm work (F=12.142,6.403,4.115,5.366,all P＜0.001).The anxiety of left-behind women was positively correlated with service content,service demand and depression (r=0.138-0.221,P＜0.01).Depression was negatively correlated with mental health service demand and service teams (r=-0.352--0.223,P＜ 0.01).Loneliness was positively correlated with service content,anxiety and depression (r=0.177-0.262,P＜ 0.01).Multiple linear regression showed that husbands go out time (β=0.326),farm work in very heavy degree (β=-0.376) and relatively heavy degree (β=-0.281),depression (β=-0.194) had a predictive effect on mental health services.Conclusion The mental health service demand of left-behind women are affected by their age,whether the only child,the age of marriage,their husbands' go out time and the degree of heavy farm work.

Objective To compare the patency of the postoperative vessel bridge grafts between the notouch technique and the conventional technique for saphenous vein harvest in the coronary artery bypass grafting. Methods A total of 70 patients underwent coronary artery bypass grafting from January 2014 to January 2015 in the First Affiliated Hospital of Zhengzhou University. They were randomly divided into a conventional technique group (saphenous vein obtained by traditional technique) and a no-touch technique group (saphenous vein obtained by notouch technique). There were 34 patients in the conventional technique group, including 16 males and 18 females with an average age of 61.6±6.4 years. There were 36 patients in the no-touch technique group, including 16 males and 20 females with an average age of 62.2±6.6 years. The 1-year postoperative coronary CT angiography (CTA) results were compared. Results Seventy patients underwent coronary CTA examination 1 year postoperatively. The patency rate of the conventional technique group and no-touch technique group were 83/116 (71.6%) and 113/122 (92.6%). Logistic regression analysis showed a statistical difference between the non-touch technique and the conventional technique (P<0.05). Conclusion The short-term patency rate of vessel bridge grafts is higher when the no-touch technique is used.

Objective:To establish a high performance size-exclusion chromatography ( HPSEC) method for the determination of impurities including polymers in latamoxef sodium. Methods:The analysis was performed on a Zenix SEC-150 column(7. 8 mm × 300 mm, 3 μm)with the mobile phase of 0. 005 mol·L-1 phosphate buffer solution [0. 005 mol·L-1 disodium hydrogen phosphate-0. 005 mol·L-1 sodium dihydrogen phosphate (61∶39), pH 7. 0] at a flow rate of 0. 8 ml·min-1. The detection wavelength was set at 254 nm. The column tempretrue was 25℃ and the injection volume was 10μl. Results:The impurities including polymers in latamoxef so-dium were completely separated from latamoxef. The linear range of latamoxef was 0. 98-97. 73 μg·ml-1(r=0. 999 9). The limit of quantitation of latamoxef was 2. 9 ng, and the detection limit was 1. 0 ng. The linear range of the total impurities was 0. 45-2. 8 mg· ml-1(r=0. 999 5). Conclusion: The established method is accurate, rapid and reproducible, and suitable for the determination of impurities including polymers in latamoxef sodium.

[ ABSTRACT] AIM:To investigate the antipyretic effect of patchouli oil on lipopolysaccharide ( LPS)-induced fe-ver in rabbits.METHODS:Male rabbits (n=42) were randomly divided into 7 groups according to their body weight and basal body temperature, including control group, model group, western medical positive group, traditional Chinese medical positive group, and high, middle and low doses (2%, 1%and 0.5%) of patchouli oil groups.Subsequently, except the controls, the rabbits were injected with LPS at a dose of 1 mL/kg (2 mg/L) through marginal ear vein to establish rabbit fever model and the rabbits in control group received the same volume of NS.The rabbits in control group and model group were injected with 0.5%Tween-80 0.5 h late, and the rabbits in the other groups were treated with correspoonding drugs. The effect of patchouli oil on the body temperature was observed, and the levels of interleukin-1β( IL-1β) and tumor nec-rosis factor-α(TNF-α) in the serum, and prostaglandin E2(PGE2) and cyclic adenosine monophosphate (cAMP) in the hypothalamus were measured by radioimmunoassay.RESULTS: The body temperature and the levels of IL-1β, TNF-α, cAMP and PGE2 in model group were significant higher than those in control group.Patchouli oil notably inhibited the body temperature in the febrile rabbits.From 1.5 h to 5.5 h after administration, the body temperatures were increased by (1.06 ±1.55), (1.62 ±1.36), (1.38 ±1.22), (0.98 ±0.98) and (0.48 ±0.95) ℃in high patchouli oil group, re-spectively.From 3.5 to 5.5 h after administration, the body temperatures were elevated by ( 1.47 ±0.73 ) , ( 1.15 ± 0.68) and (0.63 ±0.54) ℃ in middle patchouli oil group, respectively.A tendency of downregulation of the elevated body temperatures was observed at every time point after administration in low patchouli oil group.Patchouli oil significantly decreased the levels of TNF-αin the serum and cAMP content in the hypothalamus, and attenuated the elevated tendency of the IL-1βlevel in the serum and PGE2 level in the hypothalamus.CONCLUSION:Patchouli oil evidently has antipyretic effect on LPS-induced fever in the rabbits.The antipyretic mechanism might be related to the inhibition of TNF-αlevel in serum and cAMP content in the hypothalamus.
