Objective To explore the effects of seven-step complex decongestion therapy (CDT) on post-operative upper limb lymphede-ma of breast cancer. Methods From August, 2015 to September, 2016, 71 patients with upper limb lymphedema after breast cancer surgery accepted CDT for 20 days, including skin care, opening of lymphatic pathway, relief of scar tissue, manual lymphatic drainage, bandage compression, air pressure wave therapy and functional exercise. The circumference of eight sites of both limbs was measured and the differ-ences were calculated before treatment, and one, five, ten, fifteen and twenty days of the treatment. Results The differences of circumfer-ence increased one to 15 days of the treatment (Z>2.03, P<0.05), and decreased 20 days of the treatment (Z=3.01, P<0.01). Conclusion CDT is effective on lymphedema after breast cancer surgery for 20 days of a course, but may worsen in the first 15 days, which may be relat-ed to acute stress response or redistribution of lymph.

Objective To investigate the incidence of healthcare-associated infection (HAI)in patients in a respiratory in-tensive care unit (RICU)of a teaching hospital,and provide reference for HAI prevention and control.Methods All pa-tients admitted to this RICU from January to December 2014 were surveyed with prospective targeted monitoring method, surveyed data were analyzed statistically.Results A total of 561 patients were surveyed,43 patients developed 44 times HAI,HAI rate and HAI case rate were 7.66% and 7.84% respectively,incidence of HAI and adjusted incidence of HAI per 1 000 patient-days were 6.26‰ and 1.79‰ respectively.The main infection site was urinary tract (45.46%,n=20). Incidence of ventilator-associated pneumonia (VAP ),catheter-related bloodstream infection (CRBSI),and catheter-associat-ed urinary tract infection (CAUTI)per 1 000 catheter-days were 2.73‰(n=13),1.57‰(n=2),and 3.78‰(n=18)re-spectively.Incidence of HAI per 1 000 patient-days between the first and second half year of 2014 was significantly differ-ent(4.59‰ vs 7.89‰;u=-1.75,P =0.04).A total of 47 pathogenic strains were isolated,the main pathogens were gram-negative bacteria(n=26,55.32%).Conclusion The major HAI in RICU is device-associated infection,it is necessary to strengthen the management of invasive procedures;targeted monitoring can find the weak links of infection control prac-tice and helpful for taking effective prevention and control measures to reduce the incidence of HAI in ICU.

In this study, the mechanism by which Ad-p27mt inhibits the growth, invasion and metastasis of transplanted liver tumor was studied by examining the effects of Ad-27mt gene transfer on the expression of Bax, Bcl-2, VEGF and MMP-9 in the transplanted liver tumors in nude mice. The model of transplanted hepatic tumor was established in nude mice. The mice were then divided into three groups, which were injected with PBS, Ad-LacZ and Ad-p27mt and the growth of the transplanted liver tumor was observed. The expressions of P27, Bax and Bcl-2 proteins were detected by Western blotting and the expressions of VEGF and MMP-9 were immunohistochemically determined. Our result showed that the tumor size, expressions of Bax, Bcl-2 proteins, VEGF and MMP-9 were all lower than those in PBS and Ad-LacZ groups and the differences were statistically significant (P<0.05). Our study suggested that Ad-p27mt could inhibit the growth, invasion and metastasis of hepatic cancer by lowering the expressions of VEGF and MMP-9.

Objective:To analyze the characteristics of clinical manifestation, auxiliary examination and gene mutation of 3-hydroxy-isobutyryl-coenzyme A hydrolase (HIBCH) deficiency to better understand this disease.Methods:The clinical manifestations and genetic results of a patient with HIBCH deficiency were analyzed. The clinical features and genetic characteristics of HIBCH deficiency were summarized based on the literature review.Results:The proband, female, one year and four months old, was admitted to Children′s Hospital Affiliated to Zhengzhou University for “vomiting and diarrhea for 15 days, dyspnea and intermittent convulsions for 13 days after digestive tract infection”. The intelligence was normal, however, the motor development was slightly delayed before onset. Physical examination showed light coma, poor response and insensitivity to light. She also had shortness of breath, weak positive three concave signs and coarse breath sound in both lungs with sputum purrs. In addition, the muscle tension of extremities was increased. Bilateral Brudzinski′s sign, Babinski′s sign and Kernig′s sign were negative. Serum hydroxybutyryl carnitine (C4OH) was increased. Cranial magnetic resonance imaging (MRI) showed atrophy in bilateral cerebral hemispheres and abnormal symmetry signals in bilateral globus pallidus and cerebral peduncle. Novel compound heterozygous variants of HIBCH, c.489T>A (p. C163*) and c.740A>G (p. Y247C), were found in the patient, which respectively inherited from her healthy parents. Her symptoms were relieved after“cocktail”therapy and symptomatic treatment. Literature related to HIBCH deficiency published all around the world was reviewed. As a result, 17 articles, including 24 cases, had been reported. The majority of patients presented with poor feeding, dystonia and progressive motor developmental delay in early infancy. Cranial MRI showed lesions in bilateral basal ganglia. Serum C4OH concentration was elevated. And compound heterozygous or homozygous variants of HIBCH gene were found in patients with HIBCH deficiency.Conclusions:The detection of serum amino acids and acylcarnitine profiles on HIBCH deficiency was relatively specific and it was helpful to make a clear diagnosis by combining with cranial MRI and genetic tests. In this study, a case of HIBCH deficiency was confirmed, which expanded the mutation spectrum of HIBCH gene. Meanwhile, summarizing the clinical and genetic characteristics of cases reported improved understanding of HIBCH deficiency.

Objective:To discuss the perioperative management strategy of the HeartCon left ventricular assist device in the treatment of adult patients with end-stage heart failure and evaluate the effectiveness of blood pump.Methods:Ten consecutive patients with end-stage heart failure treated with the LVAD HeartCon at the Department of Cardiovascular Surgery, Jiangsu Province Hospital from July 2021 to July 2023 were enrolled in this study. The clinical data and follow-up results were retrospectively analyzed. Blood pump parameter, cardiac function classification, liver and kidney function, coagulation, myocardial markers, N-terminal pro-B-type natriuretic peptide, von Willebrand factor antigen, echocardiography, cardiothoracic ratio, and 6-minute walking distance test (6MWT) were evaluated before and after implantation of LVAD in 30, 60, 90, 180, 360, 540, and 720 days. EQ-5D-5L questionnaire was used to evaluate the quality of life.Results:There were 9 males and 1 female with a mean age of (53.7±9.7) years. All patients survived. Renal insufficiency occurred in 1 patient and recurrent aseptic granuloma occurred in 1 patient. There were no significant differences in aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), serum creatinine (Scr), blood urea nitrogen (BUN), right ventricular fractional area change (FAC) and tricuspid annular plane systolic excursion (TAPSE) between pre-operation and 30, 60 and 90 days post-operation( P>0.05). The levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), von Willbrand factor (vWF) antigen, left ventricular end-diastolic diameter (LVDd) and cardiothoracic ratio decreased significantly on the 30th, 60th and 90th day after operation ( P<0.05). The left ventricular ejection fraction (LVEF), 6MWT and EQ-5D-5L scores were significantly increased at 30, 60 and 90 days after operation compared with those before operation ( P<0.05). Conclusion:With the left ventricular assist device HeartCon, the cardiac function and quality of life of patients were significantly improved within 3 months after operation, and no serious complications were observed, proving that the device is safe and effective.

Objective To determine the scores of patients with a confirmed diagnosis of drug-induced liver injury(DILI)using Roussel Uclaf Causality Assessment Method(RUCAM),Maria&Victorino assessment scale,and Revised Electronic Causality Assessment Method(RECAM),to compare the accuracy of the three scales in diagnosis,and to investigate their clinical significance in the diagnosis of DILI.Methods A total of 98 patients with a confirmed diagnosis of DILI who were hospitalized in Peking University First Hospital from January 2011 to December 2022 were enrolled,with liver biopsy results supporting DILI and a clear history of medication.Clinical data were collected from all subjects,and the above causality assessment scales were used for scoring.The chi-square test was used to analyze the diagnostic accuracy of the causality assessment scales,and the weighted kappa coefficient was used to analyze the consistency between the three scales.Results For all patients with DILI enrolled,RECAM had the highest accuracy,with a significant difference compared with RUCAM(χ2=5.667,P=0.017).RUCAM and RECAM had moderate consistency in diagnosis(κw=0.469),while RECAM and Maria&Victorino scale had poor consistency(κw=0.156).For the patients with acute DILI,RECAM,RUCAM,and Maria&Victorino scales had a diagnostic inconsistency rate of 3.7%,11.1%,and 42.6%,respectively;for the patients with hepatocellular type DILI,the three scales of a diagnostic inconsistency rate of 8.9%,21.4%,and 62.5%,respectively;for the patients with cholestasis type or mixed type DILI,the three scales of a diagnostic inconsistency rate of 10.0%,22.5%,and 47.5%,respectively.Conclusion The use of RECAM and RUCAM scales in acute DILI can improve diagnostic rate,and for hepatocellular type DILI and DILI with the clinical manifestation of cholestasis(cholestasis type DILI and mixed type DILI),the use of RECAM and RUCAM scales can also improve diagnostic rate.The selection of causality assessment scales with a relatively high accuracy based on the course and clinical classification of the disease may help to further improve clinical diagnostic rate.

OBJECTIVE: To assess the value of detecting the rearrangement of mixed lineage leukemia (MLL) gene in children with acute mononuclear leukemia (AML). METHODS: Dual-color fluorescence in situ hybridization (FISH) probe was used to detect MLL gene rearrangement in 68 children with AML by interphase FISH. The results were compared with that of conventional G banding chromosomal analysis. RESULTS: Among the 68 children, 28 were detected by FISH with positive hybridization signals, with a detection rate for MLL gene rearrangement being 41.2%. Twelve (17.6%) reciprocal translocations and interruption of 11q23 were detected by G banding analysis. The difference in the detection rates between the two methods was statistically significant (P< 0.05). CONCLUSION The sensitivity of FISH assay for MLL gene rearrangement was significantly higher than that of G banding chromosomal karyotyping. Combined use of both methods for children with AML can improve the detection rate of MLL gene rearrangements and provide crucial clues for clinical diagnosis, treatment and prognosis.
