Soldiers are a group whose mental level are significantly low when special tasks in military exercises and actual combat training and other military stress. And one of main reasons caused in combat effectiveness reducing or potential non-combat loss is psychological and physiological and pathological damage which caused by military stress. This article reviewed the research about psychological stress reaction under military stress in the past years.

Objective To explore expression of endogenous ouabain(EO) in multiple adrenal tumors.Methods Thirty-one cases of adrenal tumors and 6 cases of healthy adrenal tissues were selected. The expression of EO in the adrenal tiss ue was detected with immunohistochemical streptavidin peroxadase conjugated(SP) method.Results Most of EO positive products were localized in cy toplasm of the zona reticularis of human adrenal cortex, and positive products s howed to be fine granular. There was no positive signal in the medulla. EO showe d on diffused positive in patients with pheochromocytoma accompanied high blood pressure[SBP:(165.22±7.61) mmHg, DBP:(105.52±4.26) mmHg], but there were neg ative in ones with normative blood pressure[SBP:(118.52±4.58) mmHg, DBP:(83±3.60) m mHg]. The expression of EO was positive in all adrenocortical hyperplasic, aden oma an d carcinoma, no matter its high or normative blood pressure. The degree of expre ssion of EO in adrenal tissues was related to the level of BP.Conclusion Expression of endogenous ouabain(EO) in health y adrenal tissue and adrenal tumors was a valuable morphological and pathophysio logical clue for the research on ouabain.

There are no reports in China, and only one case is reported abroad. We analyzed the clinical data of one case of bacterial meningitis caused by Brevundimonas vesicularis in our department, in order to improve the understanding of the disease.

Background:CT portography(CTP)permits comprehensive evaluation of portal vein and its collateral pathways. It is widely used for assessment of portal hypertension in clinical practice. Aims:To assess the value of CTP in esophagogastric varices in cirrhotic patients. Methods:A retrospective cohort study was performed in 143 cirrhotic patients admitted from Jan. 2013 to Sep. 2015 at the Affiliated Hospital of Qingdao University. All patients fulfilled the inclusion criteria and underwent CTP and gastroscopy within 7 days after admission. According to the occurrence of gastrointestinal bleeding at admission,patients were allocated into two groups:bleeding group( n = 70 ) and non-bleeding group( n = 73 ). Consistency of the results of CTP and gastroscopy was analyzed by kappa coefficient;the accuracy of CTP parameters, including diameters of main portal vein(MPV),splenic vein(SPV)and left gastric vein(LGV)for prediction of variceal bleeding was evaluated by ROC curve. Results:CTP and gastroscopy had a good consistency in typing and grading of esophagogastric varices,with the kappa value of 0. 793 and 0. 775,respectively. The diameters of MPV,SPV and LGV were significantly higher in bleeding group than in non-bleeding group(P < 0. 01),and their area under the ROC curve (AUC)in predicting variceal bleeding was 0. 741,0. 627 and 0. 816,respectively. The accuracy of diameter of LGV was superior to that of MPV and SPV. With the cutoff value of 6. 1 mm,the sensitivity and specificity of diameter of LGV were 65. 71% and 84. 93% ,respectively. With the cutoff value of 16. 3 mm,the sensitivity of diameter of MPV was 75. 71% , which was higher than that of LGV and SPV. Conclusions:CTP can be used in clinical diagnosis of esophagogastric varices in cirrhotic patients,and two CTP parameters,the diameters of LGV and MPV,might be helpful for prediction of variceal bleeding.

This study was aimed to observe the influence of Discornin Tablets on activation nuclear transcription factor NF-κBp65 of rheumatoid arthritis (RA) cell model as well as the expression of MMP-9, VEGF and tumor necrosis factor-α (TNF-α). Interleukin-17 (IL-17) and TNF-α were used for stimulating RSC-364 cells. Discornin Tablets at different concentrations were used for intervention. The influence of Discornin Tablets in different concentrations on cell viability was detected by MTT method. Expressions of NF-κBp65 and its inhibitory protein (IκB-α) in each group were detected by western blot method. Changes in VEGF, MMP-9 and TNF-α protein levels in cell broth supernatant were checked by ELISA. The results showed that Discornin Tablets can promote the expression of κB inhibitory pro-tein, reduce the high expression of NF-κB protein level, and inhibit the cellular secretion of VEGF, MMP-9 and TNF-α. It was concluded that Discornin Tablets had negative regulation effect on nuclear transcription factor κB of RSC-364 cells. It can increase the expression of IκB-α, as well as reduce the secretion of inflammation factors and blood vessel newborn factors. It suggested that Discornin Tablets may have the potential regulation effect on RA.

Objective To investigate the impact of PET-CT on the target volume delineation and precise radiothera?py planning for patients with advanced non-small cell lung cancer (NSCLC). Methods PET-CT scanning was performed in 30 histologically proved NSCLC patients. The gross tumor volume (GTV) was delineated, and radiotherapy planning was es?tablished with identical parameters based on the CT image and PET-CT fused image, respectively. The differences of doses between GTV, planning target volume (PTV) and organsat rise (OAR) were compared. Results PET-CT image results changed the target volume delineation in 30 patients with 8 increased and 22 decreased. There were no differences in GTV and PTV between the VGTV and VPTV statistically, although PET-CT image changed conventional CT image size sketch of GTV and PTV. The V20 of total lung decreased in the PlanPET-CT compared with that of PlanCT (P<0.05), but no differences were found in the V30 of total lung, mean lung dose (MLD), the data of spinal cord, esophagus and heart. Conclusion PET-CT may reduce the radiation injuries in the lung and improve the target dose.

Objective:To analyze the injury characteristics of peritalar dislocations using ankle models reconstructed with software Mimics.Methods:A retrospective study was conducted to analyze the medical records of 36 patients with peritalar dislocation who had been treated at Department of Orthopaedics, The Fourth Hospital of Wuhan from January 2008 to April 2022. There were 28 males and 8 females with an age of (46.0±14.6) years, and 16 left and 20 right limbs. Their CT data were imported into software Mimics to reconstruct ankle models to observe the fractures of the postero-medial process of the talus, the affiliated injuries to the surrounding bone structures outside the talus, and the complete or incomplete dislocations of the talonavicular articulation.Results:32 patients (88.9%, 32/36) had fracture of the postero-medial process of the talus, and 24 patients (66.7%, 24/36) a total of 33 affiliated injuries to the surrounding bone structures outside the talus, including 12 lateral malleolus ones, 4 medial malleolus ones, 7 scaphoid ones, 6 calcaneus ones, 3 fractures of the cuboid and 1 fracture of the fifth metatarsal. Sixteen patients were complicated with 1 affiliated injury, 7 patients with 2 affiliated injuries, and 1 patient with 3 affiliated injuries. The 8 patients with 2 or more affiliated injuries all had complete dislocation of the talonavicular articulation. Of the 36 patients, 26 had complete dislocation of the talonavicular articulation and 10 incomplete dislocation of the talonavicular articulation. The incidence of affiliated injuries [84.6% (22/26)] in the patients with complete dislocation of the talonavicular articulation was significantly higher than that [20.0% (2/10)] in those with incomplete dislocation of the talonavicular articulation ( P=0.001). Conclusions:Most of the peritalar dislocations are combined with the fracture of the postero-medial process of the talus. The incidence of complete dislocation of the talonavicular articulation is high. Patients with complete dislocation of the talonavicular articulation are more likely to have an affiliated injury, or even more than two injuries.

OBJECTIVEThrough comparing the literature on the randomized controlled trials (RCTs) of acupuncture for anxiety in Chinese and English versions, the participants, the interventions and the outcomes of the therapeutic effect evaluation in acupuncture treatment for anxiety were analyzed so as to provide the references to the high quality clinical research in the future.

METHODSThe literature was retrieved on RCTs of acupuncture for anxiety at home and abroad. According to the principles and the methods of the evidence-based medicine, the information on the type of clinical research, participants, interventions and outcomes was extracted and analyzed.

RESULTSA total of 106 valid papers of the Chinese and English versions were collected. In the study at home and abroad, the concepts and recognitions were indistinct among anxiety disorder, anxious emotion and secondary anxiety disorder. The diagnostic criteria were different. Regarding the intervention, the body acupuncture was predominated in the study at home and abroad, focusing on the mind regulation. The acupoints were mainly selected for tranquilizing the mind, promoting the circulation of the governor vessel and removing irritability. Additionally, the auricular acupuncture was often adopted in the treatment of anxious emotion in foreign countries. Regarding the outcomes in the effect evaluation, the scales were not so standardized in the selection and application. The analysis was limited on the factors of the anxiety scales and the survival quality.

CONCLUSIONThere are the differences in the diagnostic criteria, participant inclusion, intervention and outcomes in the clinical research of anxiety treated with acupuncture at home and abroad. A rigorous design is required in the high quality clinical research for the evaluation on the therapeutic effects of acupuncture on anxiety.

Objective To evaluate the efficacy and safety of tigecycline combined with cefoperazone-sulbactam sodium in the treatment of multi-/extensively-drug resistant Acinetobacter baumannii(MDRAB/XDRAB)associated central nervous system(CNS)infection,and to provide clinical evidence for antibiotic treatment of MDRAB/XDRAB-related intracranial disease.Methods The Wanfang Data Knowledge Service Platform,Chinese Biomedical Literature Database,VIP Chinese Science and Technology Journal Full-text Database,China National Knowledge Infrastructure(CNKI),Pubmed,Embase database,and Cochrane Library were searched to extract the literature of randomized controlled studies on tigecycline and cefoperazone sulbactam in the treatment of MDRAB/XDRAB CNS infection until September 1st,2022.The included studies were assessed for quality using the Cochrane Collaboration Risk of Bias assessment tool,and valid data were extracted and meta-analyzed using RevMan5.4 software.Results A total of 184 articles were screened and 4 Chinese RCTs were finally included,with a sample size of 267 cases.Meta-analysis showed that the overall efficacy of combination therapy for MDRAB/XDRAB CNS infection was better than monotherapy[OR = 4.30,95%CI =(1.93,9.58),P＜0.01].Combination therapy had a better bacterial clearance[OR=4.20,95%CI=(2.08,8.48),P＜0.01].And combination therapy resulted in a lower incidence of adverse effects[OR= 0.19,95%CI =(0.05,0.67),P＜0.05].There was no apparent difference in cure rate between combination therapy and monotherapy(P＞0.05).Conclusion Current evidence suggests that tigecycline combined with cefoperazone-sulbactam sodium may have better clinical efficacy and safety than monotherapy for MDRAB/XDRAB CNS infections.Limited by the number and quality of included studies,needs to be verified by more and higher-quality studies.
