0.05).After treatment,in neuromus- cular electric stimulation therapy group and ice-massage therapy group,SSA scores and degrade of SaO_2 were improved. There was significant difference between before and after treatment(P

Objective:To explore the influence of intensive analgesia on the incidence of post-traumatic stress disorder (PTSD) in acute trauma patients, and to develop new ideas for the prevention and treatment of PTSD.Methods:From January 2018 to November 2019, a prospective study was conducted on trauma patients who visited the Emergency Center of Affiliated Hospital of Xuzhou Medical University and met the enrollment criteria. The patients were divided into the intensive analgesia group (< 4) and non-intensive analgesia group (≥ 4) according to the mean pain score in 30 days. The epidemiological data, trauma-related parameters, analgesic schemes, VAS score, PCL-5 score, HADS score and incidence of PTSD of enrolled patients were collected. Appropriate statistical methods were used to analyze differences among the indicators between the two groups.Results:Eighty-four acute trauma cases were included in the study, 39 cases in the intensive analgesia group and 45 in the non-intensive analgesia group. There was no significant difference in baseline data between the two groups (all P>0.05). The incidence rate of PTSD and PCL-5 score of patients in the intensive analgesia group were all significantly lower than those in the non-intensive analgesia group in 1 month after the trauma (all P< 0.05). The HADS anxiety and depression scores of patients in the intensive analgesic group were significantly lower than those in the non-intensive analgesic group (all P< 0.05). All the analgesics were converted into the dosage of dezocine for comparison. The total dosage of analgesics (dezocine) used in patients of the intensive analgesia group was significantly higher than that in the non-intensive analgesia group within 30 days after injury ( P< 0.05). Conclusion:In the acute trauma patients, intensive analgesia after trauma can significantly reduce the incidence of PTSD as well as improve anxiety and depression symptoms.

Objective:To investigate the relationship between the changes in inflammatory markers levels and the onset of post-traumatic stress disorder (PTSD) in the early stage of acute trauma..Methods:From January 2018 to June 2020, patients with acute trauma who were admitted to the Affiliated Hospital of Xuzhou Medical University were selected as subjects. Peripheral venous blood was collected on admission, on the 3rd and 7th day after trauma for routine blood test, C-reactive protein (CRP) and procalcitonin (PCT). The neutrophil to lymphocyte ratio (NLR) was calculated. The PCL-5 scale was used to evaluate PTSD symptoms one month later. The patients were divided into the PTSD group and non-PTSD group with the score of 38 as the boundary. The change rule of NLR in the PTSD group and the non-PTSD group were analyzed.Results:Ninety-one trauma patients were enrolled, including 23 patients in the PTSD group and 68 patients in the non-PTSD group. Compared with the healthy control group, the NLR of 91 trauma patients on admission, on the 3rd and 7th day were significantly higher (all P< 0.01). The NLR of the PTSD group was increased on the 7th day after trauma, which was significantly higher than that of the non-PTSD group ( P= 0.025). The non-PTSD group showed a decreasing trend, of which NLR on the 7th day was significantly lower than that on admission ( P= 0.001). In addition, high level of NLR on the 7th day after trauma (β= 0.206, P= 0.01) was a risk factor for PTSD onset. Conclusions:Dynamic monitoring of the changes in NLR after acute trauma would be of great clinical value to early warning of PTSD.

Diabetic rats were induced by intraperitoneal injection of streptozotocin.TUNEL and immunohistochemistry results showed that the renal tubular cell apoptosis index(AI)and Bax protein expression were significantly reduced,and the Bcl-2 protein expression in glomeruli was significantly increased in diabetic rats with stable hyperglycemia treated by benazepril compared with diabetic rats with stable hyperglycemia treated by vehicle(all P

Objective To investigate the diagnostic value of dual-energy CT pulmonary angiography (DE-CTPA) and dual-energy CT lung perfusion (DE-CTLP) in the assessment of pulmonary embolism comparing with pulmonary ventilation-perfusion scintigraphy. Methods Fifty patients suspected of PE (26 males, 24 females) underwent both DE-CTPA, DE-CTLP and pulmonary ventilation-perfusion scintigraphy. The results were compared and the correlation between the intravascular clots in DE-CTPA and the perfusion defects in DE-CTLP was analyzed. The sensitivity, specificity and accuracy of DE-CTLP for PE were assessed according to scintigraphic results which was considered as a "gold" standard. Result ( 1 ) Of 50 cases,920 segments in 46 cases were diagnostable, 4 cases were not included because of the poor image quality. lntravascular clots were found in 262 segments on DE-CTPA and perfusion defects in 266 segments were identified on DE-CTLP, while 268 segments were positive on scintigraphy. (2) The perfusion defects on DE-CTLP were correlated well with the clots on CTPA ( r = 0. 883, P < 0. 01 ). The Dual energy CT Lung perfusion imaging had a good consistence with scintigraphy (Kappa = 0. 940, P <0. 01 ). The sensitivity, specificity, positive and negative predictive value were 96. 2% (279/290), 98.0%(641/654), 95. 5% (279/292) and 98. 3% (641/652), respectively. (3)The radiation dose of DE-CTPA and CE-CTLP scan was(4. 37 ± 0. 47) mSv by using CareDose 4D technique. Conclusion DE-CTPA and CE-CTLP can provide pulmonary vascular morphology and parenchyma perfusion information which are useful and valuable for the diagnosis of PE.

OBJECTIVETo investigate the effect of Kangning granules on inflammatory and immunology.

METHODPedal swelling induced by 1% agar in mice, dermal capillary hyper-permeability induced by histamine in rats were used to evaluate the anti-inflammatory of Kangning granules, and the clearance rate of intravenous charcoal particles was used to study its effect on non-specific immunologic functions. Serum haemolysin level and the number of antibody secretory cells in spleen were determined to assess its effects of specific immunologic functions. MTT colored method was used to determine the effect of Kangning granules on T- or B-Lymphocytes proliferation.

RESULT5, 10, 20 g x kg(-1) of Kangning Granules significantly inhibited pedal swelling induced by agar in mice (P < 0.05, P < 0.01). 2.4, 4.8, 9.6 g x kg(-1) of Kangning Granules evidently decreased dermal capillary hyper-permeability induced by histamine in rats (P < 0.05, P < 0.01). 10, 20 g x kg(-1) of Kangning Granules enhanced the phagocytic function and phagocytosing velocity in mice (P < 0.05). 5, 10, 20 g x kg(-1) of Kangning Granules obviously increased serum haemolysin level and the number of antibody secretory cells in spleen (P < 0.05, P < 0.01). 20 g x kg(-1) of Kangning Granules promoted B-Lymphocytes proliferation (P < 0.05).

CONCLUSIONKangning granules significantly inhibited inflammatory reaction and increase immune functions in animals.

OBJECTIVETo set up random amplified polymorphic DNAs (RAPD) method in genotyping Neisseria gonorrhoeae on DNA level, and to explore its use to trace the source of infection.

METHODSFour different pretreatments were used to extract the Neisseria gonorrhoeae genomic DNA with its advantages and disadvantages compared. Arbitrary sequence was then used to amplify the genomic DNA of Neisseria gonorrhoeae and RAPD fingerprint maps was applied to distinct the Neisseria gonorrhoeae strains. Finally, RAPD fingerprint of Neisseria gonorrhoeae strain between patient and his/her sexual partner was compared.

RESULTSCetyltrimethylammonium bromide method was classical in extracting genomic DNA, and could get integrated genomic DNA and good fingerprint maps, since main segments were common to all the Neisseria gonorrhoeae but some were different among strains so that the fingerprint of different Neisseria gonorrhoeae were distinctive. However, fingerprint maps of Neisseria gonorrhoeae collected from sex partners were quite similar.

CONCLUSIONBased on genomic levels, effective fingerprint maps could be identified and to classify the Neisseria gonorrhoeae into different genotypes. RAPD fingerprint maps could be used to trace the source of infection.

OBJECTIVEUsing molecular epidemiology methods to investigate relationship between genotypes and drug-resistance of neisseria (N.) gonorrhoeae in Shanghai area.

METHODSA random amplified polymorphic DNA (RAPD) fingerprint method at the molecular level was used to differentiate the strains which were isolated from the outpatients of sexually transmitted disease clinics. The sensitivity to antibiotic of the 78 N. gonorrhoeae strains on 9 different antibiotics was tested and the relationship between different genotypes and phenotypes was studied.

RESULTSSelected RAPD primer could give out a group of amplification polymerase chain reaction bands with some main segments common to all the N. gonorrhoeae strains tested and some segments were different among the N. gonorrhoeae strains. All the 78 N. gonorrhoeae strains could be classified as three different groups (I, II and III). The strains could also be distinguished as four types (A, B, C and D) according to drug-resistance status. Using correspondence analysis method, the relationship between the three genotypes and four resistance types could be identified.

CONCLUSIONRAPD fingerprint seemed a useful genotyping method and could be used for molecular epidemiological studies.
