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 explore the effect of ultra-early nursing intervention on postoperative cognitive behavior and prognosis of patients with cerebral hemorrhage.Methods:Using the convenient sampling method, a total of 82 patients with cerebral hemorrhage who were admitted to the First Affiliated Hospital of Zhengzhou University from March 2019 to January 2021 were selected as the research objects. According to the random number table method, they were divided into the control group and the observation group, with 41 cases in each group. Both groups received surgical treatment. The control group received routine nursing, while the observation group received ultra-early nursing intervention on the basis of routine nursing when vital signs were stable 48 hours after operation. The differences in neurological function (National Institutes of Health Stroke Scale, NIHSS) , cognitive function (Loewenstein Occupational Therapy Cognitive Assessment, LOTCA) and activity of daily living scores were compared between the two groups at 48 hours and 1 month after operation.Results:The NIHSS score at 1 month after surgery in both groups was lower than that at 48 hours after surgery and the NIHSS score at 1 month after surgery in observation group was lower than that in control group ( P<0.05) . The LOTCA dimension scores of the two groups at 1 month after operation were higher than those at 48 hours after operation and the LOTCA dimension scores of the observation group at 1 month after operation were higher than those of the control group ( P<0.05) . The activity of daily living scores of the two groups at 1 month after operation were higher than those at 48 hours after operation and the activity of daily living score of the observation group at 1 month after operation was higher than that of the control group , the differences were statistically significant ( P<0.05) . Conclusions:Ultra-early nursing intervention can effectively promote the recovery of postoperative neurological function and cognitive function in patients with cerebral hemorrhage and improve the activity of daily living of patients.

Objective: To explore the application value of 3.0 T MultiVane XD (MVXD) technique in female patients with uterine adenomyosis and fibroids. Methods: Patients diagnosed with uterine fibroids with ultrasound and suspected of adenomyosis were involved prospectively from March to May 2018, 3.0 T pelvic MRI examinations were performed during peri-ovulatory period. Axialconventional turbo spin echo (TSE) T₂WI, axial MVXD T₂WI, sagittal conventional TSE T₂WI and MVXD sagittal T₂WI were acquired. Two observers rated those 4 series in the aspects of sharpness of uterine border, motion artifacts, identification capability of lesions, confidence of diagnosis and overall image quality. Cohen Kappa analysis was used to evaluate the consistency of scores between 2 observers. Scores of TSE T₂WI and MVXD T₂WI qualities were compared using Wilcoxon matched-pairs signed-ranks test. Results: Twenty patients were enrolled. Axial conventional TSE T₂WI, axial MVXD T₂WI were aquired on all of them. Sagittal conventional TSE T₂WI, sagittal MVXD T₂WI were aquired on 19 among them. Nine patients had only obvious adenomyosis, 6 had only uterinefibroids, and 5 had adenomyosis and uterine fibroids. Compared to conventional TSE technique, scores of two observers in the sharpness of uterine border, motion artifacts, and overall image quality is higher by MVXD with significant difference (P<0.05). The Kappa values for image quality scores of two observers ranged from 0.615 to 0.971, the agreement was good or very good. Conclusion Applying MVXD T₂WI technique to patients with uterine fibroids and adenomyosiscould improve image quality, without sacrificing the ability to recognize and diagnose lesions, compared to conventional TSE T₂WI technique.

OBJECTIVE: To investigate the prevalence and relevant influencing factors of gynecological diseases of grassroot level female medical staffs. METHODS: A total of 2 308 female medical workers from county, town and village in hengxian County of Guangxi Zhuang Autonomous Region were selected as study subjects by cluster sampling method. The basic information, occupational history, reproductive health and fertility of these subjects were investigated by Reproducetive Health Survey Questionnaine of Female Workers. RESULTS: The total prevalence of gynecological diseases in female medical staffs was 21.6%. Among them, the prevalence of genital tract infections was 15.6%, and gynecological tumors was 6.0%. The top three gynecologic diseases were vaginitis(9.2%), uterine fibroids(4.3%) and cervicitis(3.5%). Multivariate logistic regression analysis results indicated that the younger the patients, the higher the risk of reproductive tract infectious diseases(P<0.01), and the lower the risk of gynecological tumors(P<0.01). The risk of reproductive tract infectious diseases and gynecological tumors in married patients was higher than that in unmarried staffs(P<0.05). The higher the number of abortions, the higher the risk of reproductive tract infectious diseases and gynecological tumors(P<0.01). The risk of reproductive tract infectious diseases was higher and the risk of gynecological tumors was lower in female shift workers than that of non-shift workers(P<0.05). CONCLUSION: Vaginitis, uterine fibroids and cervicitis are the main gynecological diseases in grassroot level female medical staffs. The incidence of gynecological diseases is related to age, history of marriage, childbirth and abortion, and work-shifts.

Objective To investigate the clinical features of cerebral venous sinus thrombosis (CVST)in patients with malignancy as well as its underlying pathogenesis. Methods The clinical data, including clinical presentation, laboratory results, neurological images were retrospectively reviewed in hospital patients with active malignant tumor and cerebral venous thrombosis from January 2006 to December 2016. Results Among the 586 CVST patients, 24 patients (4.10%) were with malignant tumor. Among these 24 patients, there were 8 males and 16 females with an average age of (39.88 ± 21.71) years old. Four patients (16.67%) had the risk factors of cerebral venous sinus thrombosis, while the other 20 patients(83.33%)had not any such risk factors.At the symptom onset of CVST, 22 patients(91.67%) had headache and focal neurological deficit, such as limbs weakness and numbness. The common substyles of malignant tumor were lung cancer (33.33%), breast cancer (29.17%)and acute lymphocytic leukemia(20.83%).Most patients(58.33%)were found to have cerebral metastasis.22 patients (91.67%) had elevated plasma D-dimmer level, and 19 patients (79.17%) had elevated plasma cancer biochemical marker levels.Conclusions Cancer-related CVST had the features including lacking conventional risk factors, elevated plasma D-dimmer and cancer biochemical marker levels.Cerebral metastasis and hypercoagulable state may be responsible for the pathogenesis of CVST.

Foodborne disease is one of the most important public health issues worldwide. China faces various and unprecedented challenges in all aspects of the food chain. Data from laboratory-based foodborne disease surveillance systems from 2013 to 2016, as well as different regions and ages, can be found along with differences in the patterns of pathogens detected with diverse characteristics. Vibrio parahaemolyticus has been the leading cause of infectious diarrhea in China, especially among adults in coastal regions. Salmonella has been a serious and widely distributed pathogen responsible for substantial socioeconomic burden. Shigella was mostly identified in Northwest China and the inland province (Henan) with less-developed regions among children under 5 years. Data from foodborne disease outbreak reporting system from 2011 to 2016 showed that poisonous animals and plant factors responsible for most deaths were poisonous mushrooms (54.7%) in remote districts in southwest regions. The biological hazard that caused most cases reported (42.3%) was attributed to V. parahaemolyticus, the leading cause of foodborne outbreaks. In this review, we summarize the recent monitoring approach to foodborne diseases in China and compare the results with those in developed countries.

Objective To study the clinical features and possible pathogenesis of acute ischemic stroke in renal cell cancer patients. Methods The clinical data from in-hospital patients with renal cell cancer who developed acute ischemic stroke were collected, including the patients with renal cell cancer who developed acute ischemic stroke during anti-cancer therapies and those patients with acute ischemic stroke who were firstly diagnosed to have renal cell cancer during anti-stroke therapies between January 2003 and December 2015. Results A total of 2516 patients with renal cell cancer were screened, and there were 36 patients (1.43%) with acute ischemic stroke. Out of the 36 patients, there were 29 men (80.56%) and 7 women (19.44%). Their age ranged from 45 to 68 years, with a average age of (65.11 ± 14.77) years. Eight patients (22.22%) had some conventional cardiovascular risk factors, while the other 28 patients (77.78%) had no such risk factors. Magnetic resonance imaging (MRI) scans at the acute stage of ischemic stroke were carried out for all these patients. Based on the diffusion weighted imaging (DWI) of MRI, 8 patients (22.22%) had single lesion and 28 patients (77.78%) had multiple lesions in different arterial territories in their brains. The pathological types of renal cell cancer were:suprarenal epithelioma (18 patients, 50.00%), papillary cell carcinoma (12 patients, 33.33%) and chromophobe renal cell carcinoma (6 patients, 16.67%). Metastases were found 10 patients (27.78%) out of the 36 patients. Blood biochemical examination showed that 28 patients had elevated plasma D-dimer level, 22 patients had elevated plasma cancer antigen (CA)125 level, and 17 patients had elevated plasma carcinoembryonic antigen (CEA) levels. Conclusions It is suggested that the renal cell cancer associated stroke is characterized by lacking of traditional risk factors and having multiple lesions in brain;and that the elevated plasma D-dimer, CA125 and CEA levels may lead to hypercoagulable state and lead to ischemic stroke eventually .

BACKGROUND:Dexmedetomidine is an effective high-selectivityα2-adrenoceptor agonist that has sedative, analgesic, anxiolytic effects, but slightly affects respiration.
OBJECTIVE:To observe the analgesic effect of dexmedetomidine on selective damage of sciatic nerve branch in a rat model by intrathecal injection.
METHODS:A total of 36 male Sprague-Dawley rats were randomly divided into normal control group, physiological saline group and dexmedetomidine group. A rat model of selective damage of sciatic nerve branch was established by knotting off the common peroneal nerve and tibial nerve in the physiological saline group and dexmedetomidine group. Rats in the dexmedetomidine group were daily injected with dexmedetomidine 3μg/kg by intrathecal injection within 14 days after injury. Rats in the physiological saline group were injected with physiological saline.
RESULTS AND CONCLUSION:Compared with the physiological saline group, the mechanical withdrawal threshold and the thermal withdrawal latency were significantly increased in the dexmedetomidine group (P<0.05). Neuronal nitric oxide synthase mRNA and protein expression levels were significantly decreased in the spinal dorsal horn (P<0.05). The injury to spinal dorsal horn neurons was obviously lessened. Moreover, neuronal nitric oxide synthase mRNA and protein expression levels and the injury to spinal dorsal horn neurons were similar between 14 days after administration and normal control group. Results indicated that intrathecal injection of dexmedetomidine could inhibit the expression of neuronal nitric oxide synthase in the spinal dorsal horn and relieve the pain induced by sciatic nerve injury.
