Objective:To explore the standardization of totally implantable venous power port of nursing process in CT enhancement and application effect of contrast medium injection, so as to provide a safer and more efficient way for contrast medium injection in CT enhanced examination for patients with malignant tumors.Methods:A non-randomized prospective study was conducted, 358 patients with malignant tumors were selected in Sun Yat-sen Memorial Hospital, Sun Yat-sen University who underwent CT enhanced examination from August 1, 2022 to July 31, 2023, 179 patients who had been implanted totally implantable venous power port were selected as the experimental group, and the standardized nursing procedure was given. The other 179 patients were the control group, using radiology routine high-pressure intravenous indwelling needle as the contrast medium access, with routine peripheral venous nursing process. The incidence of contrast medium extravasation during CT enhanced examination was observed and compared between the two groups.Results:All the patients were included. There were 85 males and 94 females, aged (55.50±11.72) years old in the control group. There were 83 males and 96 females, aged (54.50±12.24) years old in the experimental group. The incidence of contrast medium extravasation was 0 in the experimental group and 3.35%(6/179) in the control group. The difference between the two groups was statistically significant (Fisher exact probability, P<0.05). Conclusions:The application of standardized nursing procedure of totally implantable venous power port to the injection of contrast medium in CT enhanced examination of malignant tumor patients, can significantly reduce the incidence of contrast medium extravasation.

Objective:To investigate the clinical significance of plasma thrombin-antithrombin complex (TAT) levels in patients with sepsis-induced cardiomyopathy(SIC).Methods:One hundred and seven sepsis patients who were admitted to intensive care units (ICU) of the 908th Hospital of Chinese PLA Logistical Support Force were enrolled in the study. Patients were divided into sepsis group ( n=79) and the sepsis-induced cardiomyopathy group ( n=28) according to whether the cardiac ultrasound examination in 2 hours after admission, and the differences of each indicators between the two groups were compared including acute physiological and chronic health score (APACHEⅡ), lactate, blood routine, liver and kidney function, cardiac troponin I, N-terminal?pro-brain?natriuretic?peptide (NT-pro BNP), conventional coagulation tests and molecular markers of coagulation [tissue plasminogen activator-inhibitor complex (t-PAIC), thrombomodulin (TM), TAT, plasmin-α2-plasmin inhibitor complex (PIC)].Logistical?regression?was?used?to analyze the?risk?factors?for sepsis-induced cardiomyopathy and the receiver operating characteristic (ROC) curve was to analyze their cut-off values. The effect of low-molecular-weight heparin anticoagulation therapy on sepsis patients with TAT>8.26 ng/ml was evaluated by Kaplan-Meier analysis. Results:Compared with the cardiac troponin I[0.02(0.01, 0.09) ng/ml], NT-proBNP [1 118.09 (333.25, 2687.00) pg/ml], lactate[1.35(0.90, 2.60) mmol/L], TAT[6.50(3.94, 12.14) ng/ml], PIC[1.256 (0.668, 2.045) μg/ml] and t-PAIC[10.50 (6.70, 21.30) ng/ml] in sepsis group, the cardiac troponin I [0.75(0.01, 6.02) ng/ml], NT-proBNP[12 125.14(4 185.89, 33 611.62) pg/ml], lactate[2.35(1.43, 4.34) mmol/L], TAT[19.85 (9.08, 45.78) ng/ml], PIC[2.115 (0.878, 4.114) μg/ml] and t-PAIC [22.03(15.61,33.20) ng/ml] levels in the sepsis-induced cardiomyopathy group were significantly increased ( P<0.05). Logistical regression showed that positive NT-pro BNP and elevated TAT levels were independent risk factors for sepsis-induced cardiomyopathy. ROC curve analysis showed that the area under the curve of plasma TAT level for predicting sepsis-induced cardiomyopathy was 0.78. The sensitivity and specificity at the cut-off value of plasma TAT level with 8.26 ng/ml were 0.82 and 0.63, respectively. Conclusions:The elevated TAT level was an independent risk factor for the development of sepsis-induced cardiomyopathy. Low-molecular-weight heparin anticoagulation therapy can improve the 28-day survival rate of sepsis patients with TAT>8.26 ng/ml.

OBJECTIVES: Intrauterine adhesions (IUA) is the damage of the basal layer of the endometrium caused by various reasons, resulting in adhesion of the uterine muscle walls to each other, which is manifested as clinical symptoms such as spanomenorrhea, amenorrhea, and infertility. Hysteroscopic adhesiolysis (HA) is the main treatment, for patients with moderate or severe adhesion or angular adhesion, the incidence of postoperative adhesion is high. Traditional Chinese medicine "Yangmo decoction" can promote endometrial growth. Three-dimensional transvaginal ultrasonography (3D-TVUS) can judge IUA and evaluate uterine receptivity through three-dimensional imaging. This study aims to investigate the value of 3D-TVUS in judging the efficacy of Yangmo decoction in the treatment of intrauterine adhesions. METHODS: The clinical data of patients who underwent HA at two different centers in department of Gynecology of Third Xiangya Hospital of Central South University and Changsha Jiangwan Hospital from January 2021 to August 2021 were retrospectively collected. A total of 275 eligible patients were included. According to the postoperative management measures, the selected patients were divided into two groups. Yangmo decoction group (n=138): the use of Yangmo decoction and uterine-shaped silicon stent post HA; Hormone group (n=137): the use of estrogen, progesterone and uterine-shaped silicon stent post HA. The preoperative general data, preoperative and postoperative 3D-TVUS parameters of the two groups were analyzed. RESULTS: The endometrial thickness of Yangmo decoction group was thicker than that of hormone group (P<0.001), the intercornual distance was wider (P=0.016), the endometrial echo was more homogeneous (P=0.018), the percentage of bilaterally visible tubal opening was higher (P<0.001), the endometrial morphology was better (P=0.012), and endometrial blood flow, endometrial motility and uterine motion were better in Yangmo decoction group than that in the hormone group (all P<0.001). CONCLUSIONS The endometrial thickness, echo, blood flow, and peristalsis, the number of visible tubal opening, uterine motion, and the intercornual distance obtained by 3D-TVUS examination are important factors to evaluate the prognosis of postoperative drug treatment for IUA. 3D-TVUS is of great significance in evaluating the efficacy of Yangmo decoction in the treatment of IUA.

Objective To investigate the value of thromboelastography ( TEG) in evaluating the prognosis of polytrauma patients. Methods A retrospective case control study was conducted to analyze the clinical data of 155 polytrauma patients admitted to 94th Hospital of People's Liberation Army from September 2015 to December 2017. There were 118 males and 37 females, aged 18-88 years [(49. 0 ± 1. 3)years]. Injury severity score (ISS) was (26. 4 ± 11. 0)points. According to the prognosis of patients 90 days after injury, the patients were divided into survival group ( 143 patients ) and death group (12 patients). The ISS on admission, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), Glasgow coma score ( GCS ) , systolic blood pressure ( SBP ) , respiratory rate ( RR ) and outcome of 90 days after injury were collected. Red blood cells( RBC) , hemoglobin( Hb) , plasma prothrombin time ( PT) , activated partial thromboplastin time ( APTT) , fibrinogen ( FIB) , international normalized ratio ( INR) , thrombin time ( TT) , platelet count ( PLT) and TEG-related indicators within 2 hours after ICU admission were collected. TEG-related indicators including TCG clotting reaction time ( R ) , clot formation rate (K), clot formation kinetics (α angle), maximum amplitude (MA), coagulation index (CI), blood clotting strength (G), elasticity constant (E) and clot lysis time (CLT) were collected within 2 hours after admission to ICU. The changes of TEG-related indicators were compared between the two groups, and logistic regression analysis and receiver operating characteristic ( ROC) curve analysis were performed. Results Compared with the survival group, ISS and APACHE II scores in the death group were significantly higher, while GCS, SBP, RR, RBC and Hb were significantly lower (P<0. 05). Compared with the survival group, death group showed significantly prolonged PT [(21. 1 ± 9. 1) s vs. (16. 5 ± 4. 3)s] as well as reduced FIB [(1. 7 ± 1. 5)g/L vs. (2. 7 ± 1. 7)g/L] (P<0. 05). Compared with the survival group, the K value in the death group was significantly prolonged [5. 2(1. 8,8. 0)min vs. 2. 9(2. 1,4. 2)min] (P<0. 05). Compared with the survival group, death group showed significant decrease in G value (3762. 4 ± 3346. 7 vs. 6366. 5 ± 3886. 1), E value (75. 3 ± 67. 0 vs. 127. 3 ± 77.7),αangle[(38.4±19.7)°vs. (49.4±16.6)°],MA[(37.4±17.5)mmvs.(52.0±13.3)mm], CI [-6. 8(-9. 5, 1. 5) vs. -2. 9 ( -5. 9, -0. 7)] and CLT [39. 2 (32. 5, 46. 9) min vs. 46. 4 (32. 7, 60.8) min] (P<0. 05). There were no significant differences in APTT, TT, INR, PLT and R between the two groups (P>0. 05). Logistic regression analysis showed that MA was significantly associated with the prognosis of polytrauma patients (OR=1. 15, 95％ CI 1. 04-1. 28, P<0. 05). The area under the ROC curve of MA was 0. 756 (P <0. 05). When the MA threshold was 43. 1 mm, the sensitivity, specificity, positive predictive value and negative predictive value of predicted survival were 77. 5％, 76. 9％, 76. 1％ and 97. 3％, respectively. Conclusion TEG index MA can determine the prognosis of polytrauma patients, and the mortality rate is significantly increased at MA<43. 1 mm.

Objective Secretion and aggregation dysfunction of platelets are closely related with uncontrollable septic inflammation and abnormal blood coagulation.This study was to investigate the effect of emodin on platelet aggregation (PA) and secretion in mice with late sepsis.Methods We randomly divided 111 healthy SPF male C57BL/6 mice into a sham operation (SO) group, a cecal ligation (CL) group, and an emodin (Em) group and treated those of the Em group intragastrically with emodin after cecal ligation.At 72 hours after operation, we recorded the survival rate of the mice, measured the platelet count and the levels of serum alanine aminotransferase (ALT) and creatinine (Cr), and detected the PA rate by aggregometry, the P-selectin level by flow cytometry, the serum 5-HT concentration by ELISA, and the expressions of Rab27 mRNA and protein by RT-PCR and Western blot, respectively.Results At 72 hours after cecal ligation, the survival rates in the SO, CL and Em groups were 100%, 60% and 66.7%, respectively.The platelet count was significantly decreased in the CL group as compared with that in the SO group ([461.00±64.77] vs [775.00±65.89]×109/L, P<0.05) but remarkably increased in the Em group ([635.20±83.57]×109/L) in comparison with that in the CL group (P<0.05);the levels of ALT and Cr were markedly higher in the CL than in the SO group (ALT: [194.02±31.85] vs [41.55±1.24] U/L, P<0.05;Cr: [1.94±0.29] vs [0.72±0.11] mg/dL, P<0.05), but lower in the Em (ALT: [162.56±31.51] U/L;Cr: [1.53±0.30] mg/dL) than in the CL group (P<0.05);the PA rate and serum 5-HT concentration were significantly reduced in the CL group as compared with the SO group (PA: [12.67±4.04] vs [43.33±2.89]%, P<0.05;5-HT: [13.18±2.31] vs [34.35±5.79] ng/L, P<0.05), but the former was remarkably elevated ([24.67±2.52]%) while the latter showed no significant difference in the Em group ([17.41±2.16] ng/L) as compared with the CL group (P<0.05);the P-selectin expression was markedly higher in the CL than in the SO group ([16.78±1.60] vs [2.33±0.14] %, P<0.05), but lower in the Em ([12.58±2.28] %) than in the CL group (P<0.05).No statistically significant differences were observed at 72 hours postoperatively among the SO, CL and Em groups in the expression Rab27b mRNA (1.85±0.04 vs 1.84±0.02 vs 1.87±0.29, P>0.05).The Rab27b protein expression was markedly lower in the CL and Em groups than in the SO group (0.093±0.015 and 0.140±0.026 vs 10.380±0.036, P<0.05) but with no significant difference between the former two groups (P>0.05).Conclusion Emodin can improve platelet count and aggregation, down-regulate the expression of P-selectin, protect the liver and kidney function, and reduce mortality from late sepsis.

Objective To investigate the status quo of cancer pain level and cancer pain self-efficacy in the patients with cancer pain and to analyze the influencing factors of cancer pain self-efficacy.Methods The cross sectional investigation was adopted.A total of 200 inpatients with cancer pain in the Affiliated Hospital and Affiliated Hospital of Traditional Chinese Medicine of Southwest Medical University from February to September 2016 were recruited as the respondents by using the convenience sampling method.The questionnaire investigation was performed by adopting the general data questionnaire from,pain degree scale and chro nic pain self-efficacy scale.Results The total score of cancer pain self-efficacy was (45.82±15.47) points,and the score of pain management self-efficacy,symptom coping self-efficacy and somatic function self-efficacy were (10.32 ± 2.93),(17.34 ± 6.22) and (18.16 ± 8.38) points respectively.The five factors of maximal influence degree on cancer pain self-efficacy were the physical exercise situation after illness(| b| =9.96),family economic status(| b| =6.89),maximal pain degree at nearest 24 h(| b | =5.44),average pain degree at nearest 24 h(| b| =4.31) and age(|b| =0.27).Conclusion The cancer pain self-efficacy in the respondents was in the middle-to-low level.The patients with smaller age,good family economic status,usual physical exercise after illness and milder degree in maximal pain within 24 h had higher cancer pain self-efficacy.

OBJECTIVE: To compare the results of the three methods of Suresight handheld autorefractor, table-mounted autorefractor and retinoscopy in examination of juveniles patients with or without cycloplegia.
 METHODS: Firstly, 156 eyes of 78 juveniles (5 to 17 years old) were examined by using WelchAllyn Suresight handheld autorefractor and NIDEK ARK-510A table-mounted autorefractor with or without cycloplegia; secondly, retinoscopy was performed with cycloplegia.
 RESULTS: The spherical power measured by methods without cycloplegia were significantly greater than those measured with cycloplegia (P<0.05); without cycloplegia, there was no significant difference in spherical power, cylindrical power and cylindrical axis between Suresight handheld autorefractor and retinoscopy (P>0.05). These results were highly consistent, suggesting a tendency towards a short sight. However, the spherical power and cylindrical power measured by table-mounted autorefractor was significantly different (P<0.05); with cycloplegia, there was significant difference in spherical power between Suresight handheld autorefractor and retinoscopy (P<0.05).
 CONCLUSION Cycloplegic retinoscopy is necessary for juvenile refraction examination. Under natural pupil situation, Suresight handheld autorefractor is better than table-mounted autorefractor, though both show a myopia tendency. Nevertheless, table-mounted autorefractor can be taken as a recommendation for the prescription of lens trial. As a strong reference for subjective optometry, retinoscopy should be the gold standard for measuring refractive errors.

Objective: To investigate the effect of adiponectin levels with its related mechanism in diabetic myocardial ischemia-reperfusion injury and ischemia post-conditioning in experimental rats. Methods: A total of 80 male SD rats were randomly divided into 6 groups: Normal sham (NS) group,n=8, Normal ischemia-reperfusion injury (NIRI) group,n=16, Normal ischemia post-conditioning (NIPO) group,n=16 and Diabetic mellitus sham (DMS) group,n=8, Diabetic mellitus ischemia-reperfusion injury (DMIRI) group,n=16, Diabetic mellitus ischemic post-conditioning (DMIPO) group,n=16. DM rats model was established by intraperitoneal injection of streptozotocin; IR model was established by occlusion of left anterior descending (LAD) coronary artery for 30 min followed by reperfusion for 120min; IPO model was established by 3 cycles of ischemia for 10s and reperfusion for10s; the rats in Sham group received silk line wrapping of LAD without occlusion. The myocardial infarction (MI) area was measured by TTC staining, plasma adiponectin level was examined by ELISA, the protein expressions of p-Akt and total-Akt were detected by Western blot analysis. Results: Compared with NIRI group, NIPO group had decreased MI area,P<0.05, while DMIRI group and DMIPO group had increased MI area,P<0.01; compared with NS group, NIRI group and NIPO group showed up-regulated expression of adiponectin and p-Akt,P<0.05 and DMS group showed down-regulated p-Akt,P<0.05. Compared with NIPO group, three DM groups presented down-regulated adiponectin and p-Akt,P<0.05. Linear correlation analysis indicated that plasma adiponectin expression level was negatively related to MI area and positively related to myocardial tissue p-Akt expression with the correlation coefifcient at 0.63 and 0.65 respectively, P<0.01. Conclusion: Down-regulated plasma adiponectin expression may cause the inactivation of PI3K/Akt signal pathway and therefore aggravate DM ischemia-reperfusion injury which cannot be protected by ischemic post-conditioning in experimental rats.

Objective To compare the clinical effect of two hemostatic methods for patients with pelvic fracture combined with hemorrhagic shock in the early stage.Methods A retrospective analysis was done on clinical data of 90 patients with unstable pelvic fracture combined with hemorrhagic shock managed by damage control resuscitation from January 2008 to December 2012.Unstable blood pressure and abdominal distension were noted postoperatively.Forty patients in Group A received laparotomy and bilateral internal iliac artery ligation from January 2008 to January 2010.Fifty patients in Group B underwent internal iliac artery embolization from February 2010 to December 2012.Comparative measurement was made on parameters of mortality,24-hour blood transfusion volume,24-hour lactic acid value,postoperative systolic blood pressure,postoperative body temperature,and postoperative prothrombin time (PT).Results Following parameters differed significantly between Groups A and B (P ＜ 0.05):mortality rate (53％ vs 12％),24-hour blood transfusion volume[(3 865.5 ±451.3)ml vs (2 108.8 ±336.4)ml],24-hour lactic acid value[(13.0 ± 2.0)mmol/L vs (5.4 ± 1.2)mmol/L],postoperative systolic blood pressure [(80.50 ± 22.73) mmHg vs (113.23 ± 20.89) mmHg],postoperative body temperature [(32.4 ± 0.2)℃ vs (36.1 ±0.3)℃],postoperative PT [(24.5 ±3.6)s vs (18.4±2.1)s].Conclusion For pelvic fracture combined with hemorrhagic shock,if the indications of abdominal viscera rupture are unclear,the interventional embolization can gain advantage over laparotomy in improving treatment success rate and reducing mortality and complications.

Objective To observe the clinical features and to identify γ-secretase gene mutations in a Chinese family with follicular occlusion triad (FOT).Methods Clinical evaluation was carried out in a family with FOT through field investigation.Peripheral blood samples were obtained from the family members and 100 unrelated healthy controls.DNA was extracted from the blood samples,and PCR was performed to amplify all the coding regions of PSEN1,PSENEN and NCSTN genes followed by DNA sequencing and comparative analysis.Results There were 14 members over 3 generations in this family,of whom,6 (4 males and 2 females) were affected by FOT.FOT was inherited in an autosomal dominant manner in this family.Clinical manifestations varied greatly among the 4 surviving affected members.DNA sequencing revealed a novel missense mutation,c.647A ＞ C (p.Q216P),in the exon 6 of NCSTN gene in the proband,which was cosegregated perfectly with affected,but not with unaffected,members in the family.The mutation was not found in any of the unrelated controls and had not been registered in the single nucleotide polymorphism (SNP) database in NCBI.Conclusions There is a novel heterozygous missense mutation,c.647A＞C in the exon 6 of NCSTN gene,which may be the molecular basis of pathogenesis of FOT in this family.
