ABSTRACT
Objective:To investigate the clinical application value of commonly used preoperative indicators of sarcopenia in predicting postoperative pneumonia in patients aged 70 years and above with esophageal cancer.Methods:A retrospective analysis was conducted on the clinical data of 398 elderly patients(≥70 years old)with esophageal squamous cell carcinoma who underwent thoracic laparoscopic radical resection of esophageal cancer in our hospital from January 2020 to December 2021.The study aimed to investigate the correlation between clinical pathological indicators and commonly used measurement indicators of sarcopenia and postoperative pneumonia.Statistical analysis was performed to analyze the data.Results:The study found that the proportion of postoperative pneumonia in esophageal squamous cell carcinoma patients aged 70 years and above was 27.9%(111 out of 398). The pneumonia group had significantly lower preoperative BMI and peak expiratory flow(PEF)measurements compared to the non-pneumonia group, with statistically significant differences( t=2.799, 2.674, both P<0.05). Logistic multivariate analysis revealed that low PEF, low psoas major muscle index(PMI), and low psoas muscle density(PMD)were the primary risk factors for postoperative pneumonia in esophageal cancer patients aged 70 years and above(Wald χ2 values were 7.577, 6.091, 6.845, all P<0.05). The risk of postoperative pneumonia in esophageal cancer patients aged 70 years and above with low PEF, low PMI, and low PMD was found to be 1.969 times higher(95% CI: 1.215-3.185, P=0.006), 1.912 times higher(95% CI: 1.143-3.205, P=0.014), and 1.832 times higher(95% CI: 1.164-2.882, P=0.009)respectively, compared to patients with high PEF, high PMI, and high PMD. Conclusions:Low PEF, low PMI, and low PMD are significant risk factors for postoperative pneumonia in esophageal cancer patients aged 70 years and older.Preoperative PEF, PMI, and PMD, which are commonly utilized measurement indicators for sarcopenia, can be utilized as early screening indicators for postoperative pneumonia.
ABSTRACT
In order to explore the medical and social problems related to postoperative lymphedema in breast cancer patients, improve the compliance of rehabilitation treatment and help patients return to society. The self-designed questionnaire was used to investigate 76 patients who met the criteria of lymphedema after breast cancer and refused or failed to adhere to rehabilitation threapy. According to the relevant measurement scale theory and method, the computer-aided software was used to analyze the data to find out the problem and analyze the cause. The prominent problems of poor compliance in patients with breast cancer after operation were successively: subjective factors, objective factors, family social and ethical factors, multidisciplinary factors, hospital management and policy issues. For the above ethical problems, we should adopt positive coping strategies to increase the compliance of patients and improve their quality of life.
ABSTRACT
Microorganisms can form biofilms, complex, heterogeneous, multicellular communities that adhere to surfaces. Biofilm formation on the surface of structures in water will accelerate structures’ corrosion, seriously affect their service efficiency and life, and significantly impact the growth of animals, plants, and human life. Hence, clarifying the mechanism of biofilm formation contributes to developing new strategies to control biofilm formation on surface and then reduce infections, biofouling, and contaminations. Biofilm-targeting strategies include the regulation of established biofilms or the modulation of single-cell attachment. In most studies, physicochemical mechanism is frequently applied to explain the initial bacterial adhesion phenomena but rarely to explain other stages of biofilm formation. This review presents a five-step comprehensive description of the physicochemical process from film formation to biofilm maturation: (1) period of film formation; (2) period of bacterial adhesion; (3) period of extracellular-polymeric-substances (EPSs) membrane formation; (4) period of regulating biofilm by quorum sensing (QS); (5) period of biofilm maturation. We first clarify how the film formed by compound molecules affects the surface’s physicochemical properties and initial adhesion, summarizing many factors that affect bacterial adhesion. We then review the types of EPSs and signal molecules secreted by bacteria after irreversible adhesion, as well as their role and QS mechanism in biofilm maturation. Finally, we discuss how bacteria or microcolonies separate from the mature biofilm by physicochemical action and summarize the morphology and adhesion characterization methods after the biofilm matures. This review redefines the role of physicochemical in the whole process of biofilm formation and provides a theoretical basis for the prevention, removal, and utilization of biofilm and other related research fields.
ABSTRACT
Objective:To explore the role of conducting a"thematic morning report"based on post-competency in the standardized residents training in hospital in the Intensive Care Unit(ICU).Methods:A total of 60 resident training physicians who participated in the standardized residents training in hospital in the ICU of this hospital from January 2020 to December 2022 were included,and randomly divided into an observation group and a control group,with 30 in each group.The observation group adopted an interactive teaching method of themed morning report based on post-competency,while the control group adopted the traditional teaching method.The assessment results of clinical theoretical knowledge and operational skills of the two groups of resident training physicians under different teaching methods were compared.The 360°assessment method was used to record the multi-directional evaluation of patients or their families,nurses,colleagues,and teaching teachers on the post-competence of resident training physicians(self-learning ability,team collaboration ability,effective communication ability,and learning interest).Results:The assessment scores of clinical theoretical knowledge and practical skills in the observation group after teaching were higher than those in the control group,with statistically significant differences(theoretical assessment:t=2.101,P<0.05;practical assessment:t=9.647,P<0.05).The post-competence scores of nurses,colleagues,and teaching teachers on resident training physicians in the observation group were higher than those in the control group after one-month regular training,and the differences were statistically significant(nurses'evaluation of self-learning ability:t=3.182,P=0.002,team collaboration ability:t=3.978,P<0.05,effective communication ability:t=2.180,P=0.0335,learning interest:t=3.884,P<0.05;colleagues'evaluation of self-learning ability:t=2.888,P=0.005,team cooperation ability:t=6.816,P<0.05,effective communication ability:t=3.833,P<0.05,learning interest:t=4.086,P< 0.05;teaching teacher's evaluation of self-learning ability:t=3.429,P=0.001,team cooperation ability:t=3.086,P=0.003,effective communication ability:t=3.493,P=0.001,learning interest:t=3.126,P=0.003).There was a statistically significant difference in the satisfaction scores of patients or their familymembers towards the two groups of resident training physicians(t=3.126,P=0.003).Conclusion:The use of the interactive teaching method of thematic morning report based on post-competency in the standardized residents training in hospital in the ICU can not only improve the theoretical practice and case analysis test scores of resident training physicians,but also improve the post-competence and the satisfaction of patients and their families.
ABSTRACT
Anatomical right superior segmentectomy has always been a difficult surgical procedure in laparoscopic liver resection. How to accurately judge the interface between liver segments, so as to achieve a true sense of anatomic resection based on portal territory is a new requirement in the era of precision liver surgery. The portal vein puncture and indocyanine green (ICG) fluorescence positive staining technique can effectively solve this problem, which has a series of advantages and certain technical requirements in anatomical right superior segmentectomy. ICG fluorescence staining can intuitively define the three-dimensional range of the liver segment, which is a more accurate navigation mode that helps liver surgeons identify the range of the right superior liver segment, thus conducting surgery more safely and normatively. The authors consult relevant studies and combined with clinical practice to explore the application value of laparoscopic ultrosound guided puncture and positive staining technique in anatomical right superior segmentectomy.
ABSTRACT
Objective:To calculate the relative biological effectiveness (RBE) value of the released low-energy electrons in gadolinium neutron capture therapy ( 157GdNCT) based on microdosimetry. Methods:The Monte Carlo (MC) code Geant4-DNA package was used to simulate the energy deposition distribution and microdosimetry parameters of low-energy electrons released during gadolinium neutron capture treatment in different sensitive target volumes and physical models on track structures. On this basis, RBE value was obtained based on the microdosimetry kinetic model (MKM).Results:The low-energy electron RBE value was highly variable in different sensitive target volumes and decreases with increasing sensitive target volumes. With 6-nm-diameter sensitive target as reference, RBE value was 1.77 for 6-nm diameter, 1.53 for 10 nm diameter with percentage difference 13%, and 1.40 for 15-nm diameter with percentage difference of 21%, respectively. The effect of different Geant4-DNA physical models on the RBE of low-energy electrons was small. Using the RBE value of 1.53 for physical model option2 as reference, the RBE values of option6 and option7 were 1.49 and 1.52, respectively, with the percentage differences of 2.6% and 0.6%, respectively.Conclusions:The RBE values of low energy electrons released by 157GdNCT in different sensitive target volumes and physical models were calculated by MKM to be 1.40-1.77.
ABSTRACT
Objectives: To evaluate the positive rate of left posterior lymph nodes of the superior mesenteric artery (14cd-LN) in patients undergoing pancreaticoduodenectomy for pancreatic head carcinoma,to analyze the impact of 14cd-LN dissection on lymph node staging and tumor TNM staging. Methods: The clinical and pathological data of 103 consecutive patients with pancreatic cancer who underwent pancreaticoduodenectomy at Pancreatic Center,the First Affiliated Hospital of Nanjing Medical University from January to December 2022 were analyzed,retrospectively. There were 69 males and 34 females,with an age(M (IQR))of 63.0 (14.0) years (range:48.0 to 86.0 years). The χ2 test and Fisher's exact probability method was used for comparison of the count data between the groups,respectively. The rank sum test was used for comparison of the measurement data between groups. Univariate and multivariate Logistic regression analyzes were used for the analysis of risk factors. Results: All 103 patients underwent pancreaticoduodenectomy successfully using the left-sided uncinate process and the artery first approach. Pathological examination showed pancreatic ductal adenocarcinoma in all cases. The location of the tumors was the pancreatic head in 40 cases,pancreatic head-uncinate in 45 cases,and pancreatic head-neck in 18 cases. Of the 103 patients,38 cases had moderately differentiated tumor and 65 cases had poorly differentiated tumor. The diameter of the lesions was 3.2 (0.8) cm (range:1.7 to 6.5 cm),the number of lymph nodes harvested was 25 (10) (range:11 to 53),and the number of positive lymph nodes was 1 (3) (range:0 to 40). The lymph node stage was stage N0 in 35 cases (34.0%),stage N1 in 43 cases (41.7%),and stage N2 in 25 cases (24.3%). TNM staging was stage ⅠA in 5 cases (4.9%),stage ⅠB in 19 cases (18.4%),stage ⅡA in 2 cases (1.9%),stage ⅡB in 38 cases (36.9%),stage Ⅲ in 38 cases (36.9%),and stage Ⅳ in 1 case (1.0%). In 103 patients with pancreatic head cancer,the overall positivity rate for 14cd-LN was 31.1% (32/103),and the positive rates for 14c-LN and 14d-LN were 21.4% (22/103) and 18.4% (19/103),respectively. 14cd-LN dissection increased the number of lymph nodes (P<0.01) and positive lymph nodes (P<0.01). As a result of the 14cd-LN dissection,the lymph node stage was changed in 6 patients,including 5 patients changed from N0 to N1 and 1 patient changed from N1 to N2. Similarly,the TNM stage was changed in 5 patients,including 2 patients changed from stage ⅠB to ⅡB,2 patients changed from stage ⅡA to ⅡB,and 1 patient changed from stage ⅡB to Ⅲ. Tumors located in the pancreatic head-uncinate (OR=3.43,95%CI:1.08 to 10.93,P=0.037) and the positivity of 7,8,9,12 LN (OR=5.45,95%CI:1.45 to 20.44,P=0.012) were independent risk factors for 14c-LN metastasis; while tumors with diameter >3 cm (OR=3.93,95%CI:1.08 to 14.33,P=0.038) and the positivity of 7,8,9,12 LN (OR=11.09,95%CI:2.69 to 45.80,P=0.001) were independent risk factors for 14d-LN metastasis. Conclusion: Due to its high positive rate in pancreatic head cancer,dissection of 14cd-LN during pancreaticoduodenectomy should be recommended,which can increase the number of lymph nodes harvested,provide a more accurate lymph node staging and TNM staging.

Tuberculosis (TB) prophylactic therapy for latent infection, which can reduce the risk for the development of active TB, is an important measure in TB control. China recommends prophylactic therapy for latent tuberculosis infection (LTBI) in some key populations to reduce the risk for TB. Contacts of patients with multi-drug and rifampicin-resistant TB (MDR/RR-TB) are at high risk for the infection with drug-resistant pathogen, however, no unified prophylactic therapy regimen has been recommended for LTBI due to exposure to MDR/RR-TB patients. This paper summarizes the current MDR/RR-TB prophylactic therapy regimen and its protection effect based on the results of the retrieval of literature, guidelines, expert consensus and technical specifications to provide reference for the prevention and control of LTBI.

Objective:To develop an ex vivo normothermic mechanical perfusion(NMP)and compare the effect of air-oxygenated NMP versus oxygen-oxygenated NMP on reducing renal injury from donor after cardiac death(DCD).Methods:All kidneys from DCD rats were subjected to 30 min in situ warm ischemia after cardiac attest.And harvested kidneys were stored for 8h under static cold preservation after NMP for 2h.In experimental groups, kidneys were subjected to either air-oxygenated NMP(group A, n=6)or oxygen-oxygenated NMP(group O, n=6). Sham operation(group C, n=6)and DCD kidneys under static cold preservation without NMP(group SCS, n=6)were employed as controls.The evaluation parameters included creatinine(Cr), aspartate amino transferase(AST)and lactate dehydrogenase(LDH)in perfusate, pathological changes by hematoxylin-eosin(HE)staining, histological criteria, expressions of myeloperoxidase and intercellular adhesion molecular-1(ICAM-1)by immunohistochemistry and Western blot, tumor necrosis factor-alpha(TNF-α)and interleukin-6(IL-6)by enzyme-linked immunoadsorbent assay and level of malondialdehyde(MDA)by thiobarbital method and activity of superoxide dismutase(SOD)by WST-8 in renal tissues.Differences between two groups were analyzed by two-tailed unpaired Student's test and differences among more than two groups by one-way ANOVA.Results:Renal arterial oxygen tensions in NMP perfusate were(576.3±68.2)mmHg with oxygen-oxygenation and(137.0±39.1)mmHg with air-oxygenation.There was significant difference( P<0.05). The pathological injury scores in groups SCS, O and A by HE staining were(7.0±0.1), (5.0±0.9)and(2.5±0.5); injury scores and the expressions of renal proximal tubular epithelial cell vacuolar degeneration in groups O and A were lower than those in group SCS( P<0.05)and injury score in group A was lower than group O( P<0.05). In perfusate, the levels of △Cr, △AST and △LDH in groups O and A were(43.9±52.8)μmol/L and(12.6±3.5)μmol/L, (532.3±52.8)U/L and(49.1±50.4)U/L and(9998.0±2014.4)U/L and(1477.0±810.4)U/L.There were significant differences( P<0.05). In perfused kidneys, the MDA level and SOD activity in groups O and A were(0.192±0.018)mmol/g, (0.162±0.023)mmol/g, (0.6±0.3)×10 3 U/g, (1.7±0.4)×10 3 U/g; TNF-α and IL-6 levels in groups O and A were(124.376±19.635)and(89.331±13.123)ng/g, and(4.038±1.026)×10 3 and(1.774±0.518)×10 3 ng/g.After air-oxygenated NMP, lower renal damage indices were characterized by a lower MDA level and a higher SOD activity, the lower levels of TNF-α and IL-6 and the lower expressions of MPO and ICAM-1 than those in oxygen-oxygenated NMP( P<0.05). Conclusions:NMP with air-oxygenation mimics renal perfusion under physiological conditions and decreases oxidative stress and inflammation injury.It may confer a better retrieval in DCD kidney against warm ischemia injury.
ABSTRACT
Objective:To explore the influencing and prognosis factors of emphysematous urinary tract infection (EUTI).Methods:The baseline clinical data of the patients admitted to Shandong University Qilu Hospital (Qingdao) from December 2013 to June 2020 and diagnosed with EUTI were analyzed retrospectively. The patients with non-EUTI (NEUTI) during the same period were selected as the control group. The baseline characteristics between the two groups were compared. Logistic regression analysis method was used to analyze the influencing factors of EUTI.Results:(1) 24 EUTI patients and 53 NEUTI patients were included in the present study. Compared with the NEUTI group, the hemoglobin level was lower ( t=-5.245, P<0.001) and the levels of blood urine nitrogen ( Z=-4.361, P<0.001), serum creatinine (Scr, Z=-4.543, P<0.001), blood glucose ( Z=-2.608, P=0.009), and triacylglycerol ( Z=-2.408, P=0.016) were higher in the EUTI group. The proportions of diabetes mellitus ( χ2=13.453, P<0.001) and chronic kidney disease ( χ2=17.936, P<0.001) in the EUTI group were higher than those in the NEUTI group. Increasing Scr was the risk factor of EUTI in patients with urinary tract infection ( OR=1.011, 95% CI 1.001-1.020, P=0.025). (2) Escherichia coli ( E.coli, 14 cases, 58.3%) was the most common causative organism. The other causative organisms included Klebsiella pneumoniae (2 cases, 8.3%), Enterococcus faecium (1 case, 4.2%), Pantoea (1 case, 4.2%), and mixed bacteria of E.coli and Enterococcus faecium (1 case, 4.2%). Ten cases of E.coli were extended-spectrum β-lactamases (ESBL)-positive. (3) Of the 24 patients with EUTI, 4 patients had adverse outcomes. The length of stay ( Z=-2.457, P=0.014), blood urea nitrogen ( t=2.432, P=0.024), shock ( P=0.002), autoimmune disease ( P=0.022), and white blood cell count ( Z=-2.091, P=0.036) were statistically different between good prognosis group ( n=20) and poor prognosis group ( n=4). However, logistic regression analysis results showed that neither was the influencing factor of poor prognosis of EUTI. Conclusions:The elevated Scr level is the independent influencing factor of EUTI among urinary infection patients. E.coli is the most common pathogenic bacteria, and ESBL-positive bacteria are common.
ABSTRACT
Objective: To compare and analyze the clinical efficacy of pancreaticoduodenectomy for distal bile duct cancer and pancreatic head cancer. Methods: Clinical data of 1 005 patients who underwent pancreaticoduodenectomy and postoperative pathological examination confirmed the diagnosis of distal bile duct cancer and pancreatic head cancer at the Pancreas Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2020 were analyzed retrospectively. There were 112 cases in the distal bile duct cancer group, 71 males and 41 females,with age (M(IQR)) of 65(15) years(range: 40 to 87 years); 893 cases in the pancreatic head cancer group, 534 males and 359 females,with age of 64(13)years(range: 16 to 91 years). The differences between clinicopathological characteristics and postoperative overall survival of the two groups were analyzed by χ2 test, Fisher's exact probability method, rank sum test or log-rank test, respectively. The difference in postoperative overall survival between the two groups was compared using Kaplan-Meier method after propensity score matching (1∶1). Results: Compared with the pancreatic head cancer group,the distal bile duct cancer group had shorter operative time (240.0(134.0) minutes vs. 261.0(97.0) minutes, Z=2.712, P=0.007),less proportion of combined venous resection (4.5% (5/112) vs. 19.4% (173/893), χ²=15.177,P<0.01),smaller tumor diameter (2.0(1.0) cm vs. 3.0(1.5) cm,Z=10.567,P<0.01),higher well/moderate differentiation ratio (51.4% (56/112) vs. 38.0% (337/893), χ²=7.328, P=0.007),fewer positive lymph nodes (0(1) vs. 1(3), Z=5.824, P<0.01),and higher R0 resection rate (77.7% (87/112) vs. 38.3%(342/893), χ²=64.399, P<0.01),but with a higher incidence of overall postoperative complications (50.0% (56/112) vs. 36.3% (324/892), χ²=7.913,P=0.005),postoperative pancreatic fistula (28.6% (32/112) vs. 13.9% (124/893), χ²=16.318,P<0.01),and postoperative abdominal infection (21.4% (24/112) vs. 8.6% (77/892), χ²=18.001,P<0.01). After propensity score matching, there was no statistical difference in postoperative overall survival time between patients in the distal bile duct cancer group and the pancreatic head cancer group (50.6 months vs. 35.1 months,Z=1.640,P=0.201),and multifactorial analysis showed that tumor site was not an independent risk factor affecting the prognosis of patients in both groups after matching (HR=0.73,95%CI:0.43 to 1.23,P=0.238). Conclusions: Patients with distal bile duct cancer are more likely to benefit from early diagnosis and surgical treatment than patients with pancreatic head cancer,but with a relative higher postoperative complication rates. The different tumor origin site is not an independent risk factor for prognosis of patients with distal bile duct cancer and pancreatic head cancer after propensity score matching.

Objective: To compare the outcomes of modified Appleby procedure and sub-adventitial divestment technique for locally advanced or borderline resectable pancreatic body cancer. Methods: A total of consecutive 58 patients(33 males and 25 females) who were diagnosed as locally advanced or borderline resectable pancreatic body cancer and underwent distal pancreatectomy at Pancreas Center, First Affiliated Hospital of Nanjing Medical University between September 2013 and May 2019 were retrospectively reviewed. The age(M(IQR)) was 62(9)years(range: 43 to 79 years). Thirty-one patients underwent distal pancreatectomy with celiac axis resection (DP-CAR) and 27 patients underwent distal pancreatectomy with sub-adventitial divestment technique(SDT). Perioperative parameters and follow-up data of these patients were analyzed. Quantitative data were compared with Wilcoxon test while categorical variables were compared with χ2 test or Fisher's exact test. Survival results were estimated by the Kaplan-Meier survival method with a Log-rank test. Results: There were no differences in age,gender,body mass index,abdominal symptoms,comorbidity or preoperative serum CA19-9 between two groups(all P>0.05). Obvious preoperative weight loss was more common in the group of SDT(48.1%(13/27) vs. 19.4%(6/31),χ²=5.431,P=0.020). Longer operative time(310(123) minutes vs. 254(137)minutes, Z=2.277,P=0.023),higher rate of combined organ resection(41.9%(13/31) vs. 14.8%(4/27),χ²=5.123,P=0.041) and longer postoperative hospital stay(15(10) days vs. 11(5)days,Z=2.292,P=0.022) were observed in the group of DP-CAR. Moreover,rate of overall morbidities was also higher (71.0%(22/31) vs. 29.6%(8/27),χ2=9.876,P=0.003),implicated by clinically relevant postoperative pancreatic fistula(61.3%(19/31) vs. 29.6%(8/27),χ2=5.814,P=0.020) in the DP-CAR group. Tumor size of the DP-CAR group was bigger(4.9(1.5)cm vs. 4.0(1.2)cm,Z=2.343,P=0.019) but no difference was seen between the DP-CAR group and SDT group in R0+R1(<1 mm) resection rate (84.0%(21/25) vs. 90.0%(18/20),P=0.678) and LNR(12.0(23.0)% vs. 9.0(18.0)%,Z=1.238,P=0.216),as well as median disease free survival(11.7 months vs. 11.4 months,Z=0.019,P=0.892) and median overall survival(16.3 months vs. 13.7 months,Z=0.172,P=0.679). Conclusions: Both DP-CAR and distal pancreatectomy with SDT are relatively safe and feasible for locally advanced or borderline resectable pancreatic body cancer. Compared with arterial resection,SDT may contribute to lower rates of postoperative complications and shorter duration of hospitalization,but no significant benefit is seen in long-term survival.

ObjectiveTo systematically evaluate the clinical effectiveness and safety of Chinese medicinal injection (CMI) in the treatment of unstable angina pectoris (UAP). MethodEight databases, i.e., China National Knowledge Infrastructure (CNKI),VIP,Wanfang Data,CBM,PubMed,EMBASE,The Cochrane Library,and Web of Science were searched for randomized controlled trials (RCT) of conventional treatment combined with CMI (treatment group) versus conventional treatment (CT)(control group)in the treatment of UAP published from database inception to March 31th 2021. Stata 16.0 was used for network Meta-analysis. ResultThirty-nine RCT involving 3 407 patients were included. As revealed by the results of network Meta-analysis, in terms of the total effective rate in angina pectoris improvement, the therapeutic protocols were ranked as Tanreqing injection(TRQI)+CT>Xiangdan injection(XDI)+CT>Ciwujia injection(CWJI)+CT=Shengmai injection(SMI)+CT>Xuesaitong injection(XSTS)+CT>Breviscapine injection(BI)+CT>Shuxuetong injection(SXTI)+CT>Kudiezi injection(KDZI)+CT>Shuxuening injection(SXNI)+CT>Danshen injection (DSI)+CT>Guanxinning injection(GXNI)+CT>Dengzhanxixin injection(DZXXI)+CT>Xueshuantong injection(XSTI)+CT>Gualoupi injection(GLPI)+CT>CT;for the total effective rate in ECG improvement, SXTI+CT>XDI+CT>TRQI+CT>CWJI+CT>XSTI+CT>BI+CT>XSTI+CT>SXNI+CT>GXNI+CT>KDZI+CT>DZXXI+CT>GLPI+CT>CT>SMI+CT;for the adverse reactions, DZXXI+CT>XDI+CT>DSI+CT>BI+CT>SMI+CT>SXNI+CT>CT>GLPI+CT>GXNI+CT>SXTI+CT>KDZI+CT>CWJI+CT;for the reduction of fibrinogen (FIB), BI+CT>SXTI+CT>XSTI+CT>CT>KDZI+CT;for the reduction of C-reactive protein (CRP), DSI+CT>DZXXI+CT>XSTI+CT>CT;for the reduction of high-sensitivity C-reactive protein (hs-CRP), SXNI+CT>KDZI+CT>SXTI+CT>DZXXI+CT>GLPI+CT>TRQI+CT>XSTI+CT>CT. The results of subgroup analyses were consistent with those of the overall Meta-analysis. ConclusionCMI combined with CT can improve angina pectoris and ECG,reduce adverse reactions,and also improve FIB,CRP,and hs-CRP to varying degrees. However,due to the differences in the quality and quantity of CMIs in RCTs,clinical application should be performed based on the specific conditions.
ABSTRACT
In order to explore the medical and social problems related to postoperative lymphedema in breast cancer patients, improve the compliance of rehabilitation treatment and help patients return to society. The self-designed questionnaire was used to investigate 76 patients who met the criteria of lymphedema after breast cancer and refused or failed to adhere to rehabilitation threapy. According to the relevant measurement scale theory and method, the computer-aided software was used to analyze the data to find out the problem and analyze the cause. The prominent problems of poor compliance in patients with breast cancer after operation were successively: subjective factors, objective factors, family social and ethical factors, multidisciplinary factors, hospital management and policy issues. For the above ethical problems, we should adopt positive coping strategies to increase the compliance of patients and improve their quality of life.
ABSTRACT
Objective:To characterize the geriatric osteoporotic pelvic fractures using 3-D computed tomography (CT) fracture mapping.Methods:Retrospectively analyzed were the 79 elderly patients with pelvic fracture who had been admitted to Department of Orthopaedics, The 7th Medical Center of PLA General Hospital between January 2017 and December 2021. There were 24 men and 55 women, aged from 60 to 98 years (average, 74.3 years). The CT scan data of the pelvis from all patients were imported into the software (Mimics Medical 18.0, Geomagic Studio 2014, Rhinoceros 6.0, and Matlab) to create a 3-D pelvic fracture model. The fracture pieces were imported into a standard pelvic template to obtain the morphology of the fracture lines after fitting. A map of fracture line distribution frequency and a fracture heat map were created by fitting the fracture lines of all patients into a common pelvic template.Results:Of the 79 elderly patients with pelvic fracture, 69 (87.3%) had fractures of both the anterior and the posterior rings. The fracture map and heat map of geriatric pelvic fractures showed the following: the fracture lines of the anterior ring were concentrated in the junction of the cancellous bone and cortical bone of the superior and inferior pubic rami; the fracture lines of the posterior ring were concentrated in the middle and posterior 1/3 of the ilium and in the sacral wing; the fracture frequencies incurred by the pubic bone, sacrum, and ilium were from the highest to the lowest.Conclusions:Fracture mapping can visually characterize the distribution of fracture lines of the geriatric pelvic fractures. Simultaneous fractures of the anterior and posterior rings of the pelvis are the most typical kind of pelvic fractures in the elderly. The junction of the cancellous and cortical bones of the superior and inferior pubic rami and the area surrounding the sacroiliac joint are the most frequent locations for the fractures.
ABSTRACT
【Objective】 To explore whether the effect of functional electrical stimulation combined with respiratory training on patients with mechanical ventilation is superior to that of single lung rehabilitation scheme. 【Methods】 We selected 90 patients with mechanical ventilation hospitalized in the central ICU of our hospital from March 2018 to October 2019 and randomly assigned them into the functional electrical stimulation group (30 cases), respiratory function training group (30 cases), and the combined rehabilitation group (functional electrical stimulation combined with respiratory training) (30 cases). The treatment time in the three groups was 40 minutes each time. The treatment was given once a day, 6 times a week, and lasted for 2 weeks. B-ultrasound was used to measure the changes of the diaphragm and calculate the score of diaphragm thickening. The success rate of weaning, incidence of ventilator-associated pneumonia (VAP), duration of mechanical ventilation, and length of stay in ICU can be quantified according to the clinical nursing records. 【Results】 There were significant differences in the success rate of weaning, incidence of VAP, time of mechanical ventilation, and length of ICU stay in the three groups. However, the success rate of weaning, incidence of VAP, time of mechanical ventilation, and the length of ICU stay in the combined rehabilitation group were better than those in the other two groups (P<0.05). 【Conclusion】 The effect of functional electrical stimulation combined with respiratory training on patients with mechanical ventilation is significantly better than that of single lung rehabilitation scheme. The former one is superior to the single rehabilitation scheme in improving the success rate of weaning, increasing the activity of diaphragm, shortening the time of mechanical ventilation, and the length of stay in ICU.
ABSTRACT
Liver resection is an important method for the treatment of benign and malig-nant hepatobiliary diseases. Due to severe surgical injury, complicated surgical procedures and operation difficulty, the postoperative complications are relatively more common, and infections are the frequent complications. Postoperative infection not only increases the economic burden and treatment difficulty of patients, but also affects the prognosis. There are many risk factors leading to postoperative infection. Controlling and improving these factors are effective measures to reduce or avoid postoperative infection. By reviewing the domestic and abroad literatures, and combined with the clinical experiences, the authors discuss the types of postoperative infection, the related risk factor and the corresponding prevention and treatment strategies after liver resection.
ABSTRACT
DNA hypermethylation is an epigenetic modification that plays a critical role in the oncogenesis of myelodysplastic syndromes (MDS). Aberrant DNA methylation represses the transcription of promotors of tumor suppressor genes, inducing gene silencing. Realgar (α-As4S4) is a traditional medicine used for the treatment of various diseases in the ancient time. Realgar was reported to have efficacy for acute promyelocytic leukemia (APL). It has been demonstrated that realgar could efficiently reduce DNA hypermethylation of MDS. This review discusses the mechanisms of realgar on inhibiting DNA hypermethylation of MDS, as well as the species and metabolisms of arsenic in vivo.

Laparoscopic anatomic hepatectomy (LAH) has been widely approved as an essential procedure for safety and availability, and has gradually become the mainstream method of hepatec-tomy. Through a renewed understanding of the Laennec capsule, the authors have found that there exists a natural gap between the Laennec capsule and the adjacent tissues, such as Glisson pedicles and hepatic veins. Consequently, Laennec capsule can serve as the anatomical approach for LAH. The left lobe, right anterior lobe and right posterior lobe has an independent Glisson pedicle respectively, which can be used to perform Glisson pedicle transection sectionectomy via Laennec capsule approach without damaging the liver parenchyma. The exposure of hepatic veins on the detached plane can also be achieved through this approach. Laennec capsule approach provides a new idea for laparoscopic anatomic liver sectionectomy, which is safe, reliable, convenient and highly repeatable.
ABSTRACT
Objective:To study the clinical features of the "migration birds" population in Hainan Province in winter presenting with acute cholecystitis.Methods:Patients who were diagnosed to suffer from acute cholecystitis in the winter months from November to February of the following year of 2017, 2018 and 2019 and admitted in Hainan Hospital of Chinese PLA General Hospital were included in this study. The "migration birds" patients who arrived in Hainan Province in less than 30 days were defined as the short-term group ( n=49), 30-89 days as the mid-term group ( n=24), more than 90 days as the long-term group ( n=48). The general information, associated medical diseases, clinical presentations, interventional strategies and in-hospital outcomes were compared, and further analyze the clinical characteristics of patients with purulent cholecystitis and non-purulent cholecystitis in the short-term group. Results:Of 120 patients, there were 49 patients in the short-term group (29 males and 20 females with an average age of 65.18±15.02 years), 24 patients in the mid-term group (13 males and 11 females with an average age of 66.21±11.93 years), and 48 patients in the long-term group (30 males and 18 females with an average of 60.73±12.54 years). The general information, interventional strategies and in-hospital outcomes were similar among the three groups. When compared with patients in the long-term group, patients in the short-term group had higher incidences of hypertension [20.83% (10/48) vs 48.98% (24/49)] and diabetes [10.42% (5/48) vs 30.61% (15/49)]. The gallbladder wall in the short-term group was significantly thicker than that in the long-term group [0.60(0.40, 0.70) cm vs 0.50(0.30, 0.60) cm, P<0.017]. The proportion of purulent cholecystitis in the short-term group was significantly higher than that in the long-term group [48.15% (13/27) vs 17.24% (5/29) , P<0.017] . In the short-term group, the incidences of silt-like stones of purulent cholecystitis [38.46% (5/13) vs 14.29% (2/14)], gallbladder perforation [30.77% (4/13) vs 0], gallbladder gangrene [53.85% (7/13) vs 7.14% (1/14)], perigallbladder effusion [76.92% (10/13) vs 14.29% (2/14)], abdominal effusion [46.15% (6/13) vs 7.14% (1/14)] were significantly higher than that of patients with non-purulent cholecystitis, (all P<0.05). Conclusion:Patients presenting with acute cholecystitis after arrival in Hainan in the short term had more severe inflammation with complications of suppuration, perforation and gangrene. Patients with hypertension and diabetes were the high risk group of patients presenting with acute cholecystitis after short-term arrival in Hainan.
