ABSTRACT

Objective:To investigate the surgical method and clinical effect of O-arm navigation mini-open burring for osteoid osteoma.Methods:Eighteen patients with osteoid osteoma were treated with O-arm guided grinding drill from June 2021 to May 2022, including 15 males and 3 females, the age was (18.4 ±10.9) years (range 2 to 44 years), and the course of disease ranged from 1 week to 3 years (mean 14.2 months). The lesions sites included 6 cases of proximal femur, 3 cases of distal femur, 4 cases of proximal tibia, 1 case of distal tibia, 2 cases of proximal fibula and 1 case of distal and proximal humerus. During the operation, the O-arm navigation was used to determine the location of the focus, the muscle and soft tissue was peeled off to the bone surface through a 1-4 cm small incision, the channel retractor was placed, and the burr was registered as a navigation recognition device to gradually remove the bone on the surface of the tumor nest, and the tumor nest was scraped with a curette for pathological examination; according to the navigation image, the focus was enlarged removed with burr and the grinding range was confirmed by the O-arm X-ray machine before the end of the operation. The patients were followed up for 6 to 15 months (mean 9.5 months). CT scans were performed before and after surgery for imaging comparison in order to figure out whether it had residual lesions or recurrence. The visual analogue score (VAS) of pain was used as a parameter for evaluating the clinical efficacy.Results:The operation time of 18 cases was 40-175 min, with an average of 89.3 min. The time required to establish navigation image was 18.0 ±4.1 min (range 13 ~ 22 min). The length of the incision was 2.7±1.1 cm (range 1-4 cm). All patients achieved complete curettage of the lesions, and osteoid osteoma was confirmed by pathology after operation. All the patients could move to the ground 24 hours after operation, and the pain was significantly relieved from 3 to 7 d after operation, and the pain almost disappeared 3 months after operation. The VAS score of 18 cases was 5.33±1.24 before surgery, 2.79±1.32 on the 3rd day, 1.86±1.21 on the 7th day, 0.86±0.93 on the 1st month, 0.33±0.48 on the 3rd month, and 0.09±0.29 on the 6th month after operation, and the difference was statistically significant ( F=58.50, P<0.001). There were no serious complications during and after operation, and the success rate of treatment (no recurrence of symptoms, no residual recurrence of imaging lesions, no serious complications after operation) was 100%. Conclusion:Treatment of osteoid osteoma with mini-open excision using burrs under the navigation of O-arm is a simple, safe, minimally invasive and efficient technique. Intraoperative precise positioning and the use of burr with navigation to remove a larger area than the tumor nest are the keys to successful treatment.

ABSTRACT

Objective:To explore the relation among self-esteem, psychological flexibility and mental health in medical students, and to provide scientific reference for mental health education for medical students.Methods:A total of 788 medical students selected from a medical university in Chongqing City were investigated with the symptom checklist 90 (SCL-90), self-esteem scale (SES), acceptance and action questionnaire-Ⅱ (AAQ-Ⅱ), and cognitive fusion questionnaire-fusion (CFQ-F). SPSS 22.0 software was used for statistical analysis. T test, ANOVA, correlation analysis and tests for mediation effects were conducted. Results:There were significant differences in self-esteem and mental health level among medical students in gender and different grades ( t=-2.55, P<0.05; F=6.53, P<0.05). Mental health, self-esteem and psychological flexibility of medical students were correlated in pairs ( r=-0.528-0.694, P<0.01). Psychological flexibility played a partial mediation role between self-esteem and mental health of medical students, and the mediating effect accounted for 60.03% of the total effect. Conclusion:Self-esteem can directly predict the mental health of medical students, and can also indirectly affect mental health through psychological flexibility. Medical universities should carry out psychological education and promotion work with pertinence.

ABSTRACT

ObjectiveTo investigate the value of percutaneous and intravenous contrast-enhanced ultrasound(P-Ⅳ-CEUS) in sentinel lymph nodes(SLNs) after resection of early-stage primary breast cancer. MethodsA retrospective analysis was done on the clinical and imaging data of 42 early breast cancer patients. Following primary tumor resection, all these patients underwent reoperation in our hospital. SLNs were examined by preoperative P-Ⅳ-CEUS and intraoperative sentinel lymph node biopsy(SLNB) was performed by using Methylene blue as a tracer. Then we analyzed the detection and false-negative rate in CEUS and SLNB respectively. By using the surgical pathological results as the gold standard, the diagnostic efficacy of CEUS for SLNs was explored. ResultsThe detection rate and false negative rate of SLNs in percutaneous contrast-enhanced ultrasound (P-CEUS) were 92.9% (39/42) and 7.1% (3/42), respectively. The detection rate in methylene blue staining was 100% (41/41) and one patient underwent neoadjuvant therapy due to biopsy-confirmed metastasis. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of P-Ⅳ-CEUS were 66.7% (2/3), 100% (37/37), 100% (2/2), 97.3% (36/37) and 97.4% (38/39), respectively. ConclusionsP-Ⅳ-CEUS after resection of early-stage primary breast cancer can accurately detect SLNs and characterize their status, which is a reliable clinical basis for reducing invasive SLNB.

ABSTRACT

OBJECTIVE To reevaluate systematic reviews/meta-analysis of efficacy and safety of tolvaptan for hyponatremia. METHODS Retrieved from CNKI, Wanfang Data, VIP, CBM, PubMed, Embase and the Cochrane Library database, systematic reviews/meta-analysis about tolvaptan for the treatment of hyponatremia were included from the inception to June 15, 2022. After screening literature and extracting data, the PRISMA statement, AMSTAR 2 scale and GRADE method were used to evaluate the reporting quality, methodological quality and evidence quality of the included literature, respectively. RESULTS A total of 6 articles were included, of which 1 was systematic review and 5 were meta-analysis, including 56 outcome indicators. All of the 6 studies had PRISMA scores ranging from 15.0 to 20.5, and the quality of them was moderate. Results of the AMSTAR 2 scale showed that the methodological quality of 5 literatures were very low, and the quality of 1 literature was low. The quality of GRADE evidence showed that there were 6 moderate-quality indicators, 13 low-quality indicators, 35 very low-quality indicators, and 2 indicators that could not be assessed due to missing data. The main factors causing degradation were limitations, inconsistency, imprecision and publication bias. In terms of efficacy, tolvaptan could effectively increase the level of serum sodium, increase urine volume, reduce body weight, reduce abdominal circumference, relieve edema, and reduce alaninetransaminase level. In terms of safety, the incidence of total adverse drug reaction induced by tolvaptan was controversial; it may increase the risk of dry mouth, thirst, frequent urination or excessive correction of serum sodium. CONCLUSIONS Tolvaptan has great efficacy in the treatment of hyponatremia, but serum sodium overcorrection should be avoided in terms of safety. Relevant systematic reviews/meta-analysis have shortcomings of low reporting quality, methodological quality and evidence quality, which may reduce the reliability of the results, so the results should be treated with caution.

ABSTRACT

Objective: To investigate the morphology and immunohistochemical (IHC) expression of pseudostratified ependymal tubules in ovarian mature teratoma (MT). Methods: Five cases of ovarian MT with pseudostratified ependymal tubules were collected from Shenzhen Hospital(Futian) of Guangzhou University of Chinese Medicine and the Eighth Affiliated Hospital of Sun Yat-sen University from March 2019 to March 2022. In addition, 15 cases of ovarian MT with monolayer ependymal epithelium from Shenzhen Hospital (Futian) of Guangzhou University of Chinese medicine and seven cases of immature teratoma (IMT) from Hainan Provincial People's Hospital from March 2019 to March 2022 were collected as control. The morphologic characteristics and immunophenotypes of pseudostratified ependymal tubules, monolayer ependymal epithelium, and primitive neural epithelial tubules were observed and compared by H&E stain and IHC expression pattern of genes related to the differentiation status of neuroepithelium, namely SALL4, Glypican3, nestin, SOX2, Foxj1, and Ki-67. Results: Mean age of the five patients of ovarian MT with pseudostratified ependymal tubules was 26 years (range from 19 to 31 years). Two tumors were located in the left ovary and three in the right. All five cases were excised, and clinical follow-up was available (mean follow-up 1.5 years; range 0.5 to 3 years). No recurrence was noted in any cases. The pseudostratified ependymal tubules of ovarian MT, which were lined with columnar or oval epithelia up to 4-6 layers, were morphologically similar to the primitive neuroepithelial tubules of IMT and different from monolayer ependymal epithelium of ovarian MT. By immunohistochemistry, SALL4 and Glypican3 were negative, Foxj1 was positive and Ki-67 index was lower in the pseudostratified ependymal tubules and the monolayer ependymal epithelium of ovarian MT. However, the primitive neuroepithelial tubules of IMT showed variably expression of SALL4 and Glypican3, were negative for Foxj1 and high Ki-67 index. All the above three groups expressed nestin and SOX2. Conclusions: The pseudostratified ependymal tubules of ovarian MT, which have morphological similarities to the primitive neuroepithelial tubules of IMT, are similar to the monolayer ependymal epithelia of the MT in immunophenotype. IHC assessment of Foxj1 and Ki-67 is helpful to differentiate the pseudostratified ependymal tubules of ovarian MT from the primitive neuroepithelial tubules of IMT.

ABSTRACT

Objectives: To analyze the long-term survival of patients with localized renal cell carcinoma after partical nephrectomy. Methods: The clinicopathological records and survival follow-up data of 2 046 patients with localized renal cell carcinoma, who were treated with partial nephrectomy from August 2001 to February 2021 in the Department of Urology, Sun Yat-sen University Cancer Center, were retrospectively analyzed. There were 1 402 males and 644 females, aged (M(IQR)) 51 (19) years (range: 6 to 86 years). The primary end point of this study was cancer-specific survival. Survival curves were estimated using the Kaplan-Meier method, and the difference test was performed by Log-rank test. Univariate and multivariate Cox analysis were fitted to determine factors associated with cancer-specific survival. Results: The follow-up time was 49.2 (48.0) months (range: 1 to 229 months), with 1 974 patients surviving and 72 dying. The median cancer-specific survival time has not yet been reached. The 5- and 10-year cancer specific survival rates were 97.0% and 91.2%, respectively. The 10-year cancer-specific survival rates for stage pT1a (n=1 447), pT1b (n=523) and pT2 (n=58) were 95.3%, 81.8%, and 81.7%, respectively. The 10-year cancer-specific survival rates of patients with nuclear grade 1 (n=226), 2 (n=1 244) and 3 to 4 (n=278) were 96.6%, 89.4%, and 85.5%, respectively. There were no significant differences in 5-year cancer-specific survival rates among patients underwent open, laparoscopic, or robotic surgery (96.7% vs. 97.1% vs. 97.5%, P=0.600). Multivariate analysis showed that age≥50 years (HR=3.93, 95%CI: 1.82 to 8.47, P<0.01), T stage (T1b vs. T1a: HR=3.31, 95%CI: 1.83 to 5.99, P<0.01; T2+T3 vs. T1a: HR=2.88, 95%CI: 1.00 to 8.28, P=0.049) and nuclear grade (G3 to 4 vs. G1: HR=2.81, 95%CI: 1.01 to 7.82, P=0.048) were independent prognostic factors of localized renal cell carcinoma after partial nephrectomy. Conclusions: The long-term cancer-specific survival rates of patients with localized renal cancer after partial nephrectomy are satisfactory. The type of operation (open, laparoscopic, or robotic) has no significant effect on survival. However, patients with older age, higher nuclear grade, and higher T stage have a lower cancer-specific survival rate. Grasping surgical indications, attaching importance to preoperative evaluation, perioperative management, and postoperative follow-up, could benefit achieving satisfactory long-term survival.

ABSTRACT

OBJECTIVE To evaluate the effect of “Cloud Pharmacy Service System” electronic management platform in medication therapy management (MTM) of chronic airway diseases. METHODS MTM module setting of “Cloud Pharmaceutical Service System” was introduced. Totally 371 patients with chronic airway disease admitted to our hospital from January 2021 to March 2022 were selected for MTM based on the “Cloud Pharmacy Service System”. The standardization of inhalation device mastery and compliance of patients before and after intervention were compared with self-made inhalation device evaluation scale and Morisky medication adherence scale-8 (MMAS-8). The satisfaction of patients with pharmacist after intervention was investigated. RESULTS “Cloud Pharmaceutical Service System” is mainly divided into 4 modules, such as medication therapy review, pharmacist intervention, personal medication record and the medication-related action plan, other functions. Among 371 patients, there were 237 outpatients (142 cases of asthma, 95 cases of chronic obstructive pulmonary disease) and 134 inpatients (19 cases of asthma and 115 cases of chronic obstructive pulmonary disease). The score of the patients using inhalation device increased from 74.76±24.71 before intervention to 99.45±2.12 after intervention (P<0.05). MMAS-8 score increased from 7.14± 1.15 before intervention to 7.88±0.44 after intervention (P<0.05). The degree of patients’ satisfaction with pharmacists reached 100% after intervention. CONCLUSIONS “Cloud Pharmacy Service System” is helpful to improve the effects of pharmaceutical service for patients with chronic airway disease by providing whole-process, online, visual and immediate MTM.

ABSTRACT

BACKGROUND@#Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations.@*METHODS@#In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively.@*RESULTS@#81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count.@*CONCLUSIONS@#In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

ABSTRACT

This study aims to investigate the expression, prognosis, and clinical significance of C5orf46 in gastric cancer and to study the interaction between the active components of C5orf46 and tarditional Chinese medicine. The ggplot2 package was utilized for differential expression analysis of C5orf46 in gastric cancer tissues and normal tissues. The survival package was used for survival analysis, univariate regression analysis, and multivariate regression analysis. Nomogram analysis was used to assess the connection between C5orf46 expression in gastric cancer and overall survival. The abundance of tumor-infiltrating lymphocytes was calculated by GSVA package. Coremine database, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) database, and PubChem database were used to search the potential components corresponding to C5orf46 gene and tarditional Chinese medicine. Molecular docking was performed to explore the binding affinity of potential components to C5orf46. Cell experiments were performed to explore the expression of C5orf46 gene in cells of the blank group, model group, and drug administration groups. As compared with normal tissues, C5orf46 expression was higher in gastric cancer tissues, which had more significant predictive effects in the early stages(T2, N0, and M0). The more advanced the tumor node metastasis(TNM) stage, the higher the C5orf46 expression and the lower the probability of survival of patients with gastric cancer. The expression of C5orf46 positively correlated with the helper T cells1 in gastric cancer and the macrophage infiltration level in gastric cancer, and negatively correlated with B cells, central memory T cells, helper T cells 17, and follicular helper T cells. Seven potential components of C5orf46 were obtained, and three active components were obtained after the screening, which matched five tarditional Chinese medicines, namely, Sojae Semen Nigrum, Jujubae Fructus, Trichosanthis Fructus, Silybi Fructus, and Bambusae Concretio Silicea. Molecular docking revealed that sialic acid and adeno-sine monophosphate(AMP) had a good binding ability to C5orf46. The results of real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot showed that, as compared with the model group, the mRNA and protein expression levels of C5orf46 were significantly lower in the drug administration groups. The lowest expression level was found at the concentration of 40 μmol·L~(-1). The results of this study provide ideas for the clinical development of traditional Chinese medicine compounds for the treatment of gastric cancer as well as other cancers.

ABSTRACT

Objective To construct a human health literacy indicator system for prevention of parasitic diseases based on Delphi method. Methods Based on literature reviews and expert interviews, a questionnaire was designed and a two-round Delphi consultation was performed. A human health literacy indicator system for prevention of parasitic diseases was constructed according to the deletion criteria and experts’ advice. Results A total of 14 experts completed the two-round consultation. The second-round authority coefficients were 0.91 to 0.96 for the first-level indicators, 0.87 to 0.97 for the second-level indicators and 0.86 to 0.97 for the third-level indicators. A human health literacy indicator system for prevention of parasitic diseases was constructed with the main framework of basic knowledge and awareness, healthy behaviors, and healthy skills, which contained 3 first-level indicators, 12 second-level indicators and 48 third-level indicators. Among the three first-level indicators, basic knowledge and awareness had the highest weighting coefficient (0.336 5), followed by healthy behaviors (0.334 9), and healthy skills had the lowest weighting coefficient (0.328 6). The three secondary-level indicators with the highest combined weights included awareness of the epidemic status (0.088 2), awareness of the resource of infection (0.085 8) and basic awareness of parasitic diseases (0.085 5). Conclusion A human health literacy indicator system for prevention of parasitic diseases is preliminarily constructed, which provides insights into the development of health literacy evaluation tools for prevention of parasitic diseases in the new era.

ABSTRACT

OBJECTIVES@#To investigate the association between maternal job burnout and adolescent depression and the mediating effect of maternal depression and parenting style.@*METHODS@#A cross-sectional study was conducted. The cluster random sampling method was used to select 2 572 adolescents from 7 middle schools in Shanghai, China, from April to May, 2021. A survey was performed for these adolescents and their mothers. The research tools included a general information questionnaire, Maslach Burnout Inventory-General Survey, Center for Epidemiologic Studies Depression Scale, short-form of Egna Minnen av Barndoms Uppfostran, and Children's Depression Inventory. A structural equation model was established, and the Bootstrap method was used to investigate the mediating effect.@*RESULTS@#The detection rate of depressive symptoms was 12.71% (327/2 572) among the adolescents. The scores of maternal job burnout, maternal depression, and negative parenting style were positively correlated with the score of adolescent depression (P<0.05), and the score of positive parenting style was negatively correlated with the score of adolescent depression (P<0.05). Maternal depression and parenting style played a mediating role between maternal job burnout and adolescent depression, including the individual mediating effect of maternal depression, the individual mediating effect of positive parenting style, and the chain mediating effect of maternal depression-negative/positive parenting style.@*CONCLUSIONS@#Maternal job burnout may affect adolescent depression through the mediating effect of depression, parenting style, and depression-parenting style, suggesting that the symptoms of adolescent depression can be reduced by alleviating maternal job burnout, improving maternal depression, increasing positive parenting behaviors, and reducing negative parenting behaviors.

ABSTRACT

OBJECTIVES@#To study the influence of family structure on depression and anxiety symptoms in adolescents and its mechanism.@*METHODS@#The cluster sampling method was used to select the students from seven middle schools in Shanghai, China. An online questionnaire survey was conducted using a self-made general status questionnaire, Childhood Trauma Questionnaire, Children's Depression Inventory, and Screen for Child Anxiety Related Emotional Disorders. The methods including one-way analysis of variance, chi-square test, binary logistic regression analysis, and mediating effect analysis were used to evaluate depression and anxiety symptoms in adolescents and the difference in childhood trauma and its mediating effect.@*RESULTS@#Compared with the adolescents from nuclear families, the adolescents from three-generation lineal families had a lower risk of depression symptoms (OR=0.794, 95%CI: 0.649-0.972, P<0.05), while those from host families had a higher risk of depression symptoms (OR=4.548, 95%CI: 1.113-18.580, P<0.05). The adolescents from inter-generational families and host families had a significantly higher score on the Childhood Trauma Questionnaire subscale of emotional neglect (P<0.05). Emotional neglect played a mediating role in the influence of inter-generational families and host families on depression symptoms in adolescents.@*CONCLUSIONS@#Parents and grandparents have a certain positive effect in family structures. Separation from parents may make adolescents perceive more emotional neglect, which may increase the occurrence of depression symptoms.

ABSTRACT

Autosomal recessive congenital ichthyosis caused by CERS3 mutations is extremely rare in clinical practice. We recently identified a family of autosomal recessive congenital ichthyosis and performed multigene exome sequencing for hereditary skin diseases to identify causative genes. Mutation analysis revealed compound heterozygous mutations of c.746A>G(from the mother) and exon12 deletion(from the father)in CERS3 were detected in the proband, which were verified by Sanger sequencing and co-segregated with the ichthyosis phenotype in the proband and her parents. These mutations were both reported for the first time. For the treatment, the proband received an oral acitretin capsules of 20 mg once daily. After 3-month follow up, the patient's lesion improved significantly.

ABSTRACT

Bone marrow mesenchymal stem cells (BMSCs) are derived from stem cells isolated from bone marrow and have the potential for multidirectional differentiation and self-renewal. Under certain conditions, BMSCs can be induced to differentiate into osteoblast (OB), chondrocyte, adipocyte, fibroblast, etc. BMSCs play an important role in maintaining the stability of bone structure and balancing bone metabolism. Promoting the proliferation of BMSCs and inducing their differentiation into OB of great significance for the clinical prevention and treatment of osteoporosis, bone defects, fracture healing, and other diseases. Because the proliferation and osteogenic differentiation of BMSCs are complex processes controlled by multiple genes and regulated by multiple signal transduction pathways, traditional Chinese medicine (TCM) happens to have the advantages of multi-bioactive component, multi-target, and multi-pathway synergism, which can affect the proliferation and differentiation of BMSCs through multiple channels and induce the proliferation of BMSCs. The transcription and expression of genes related to osteogenesis can be enhanced to promote the differentiation of BMSCs into OB, so as to achieve the purpose of preventing and treating osteoporosis, bone defects, and other bone diseases. Based on the literature on the intervention of TCM monomers and compounds in the proliferation and osteogenic differentiation of BMSCs, this study reviewed TCM monomers and compounds in promoting the proliferation and osteogenic differentiation of BMSCs by regulating secreted glycoprotein (Wnt), neurogenic locus notch homolog protein (Notch), mitogen-activated protein kinase (MAPK), phosphatidylinositol-3 kinase (PI3K) /protein kinase B (Akt), bone morphogenetic protein (BMP)/Smad, Janus kinase (JAK)/signal transducer and activator of transcription protein (STAT), osteoprotegerin (OPG)/receptor activator of nuclear factor-kappa B (RANK)/RANK ligand (RANKL), and other signaling pathways to provide new ideas for the research and clinical application of Chinese medicine in the prevention and treatment of orthopedic diseases.

ABSTRACT

OBJECTIVE To investigate the efficacy and safety of aerosol inhalation of polycolistin B in the treatment of severe pneumonia combined with mechanical ventilation, and to provide a reference of real-world data for clinical drug therapy. METHODS A retrospective cohort study was conducted to analyze the clinical data of 87 patients with severe pneumonia combined with mechanical ventilation at the First Affiliated Hospital of Shandong First Medical University from January 2021 to February 2023. According to route of administration, all patients were divided into combined group (24 cases, receiving aerosol YXH2021ZX013) inhibition of polycolistin B combined with intravenous dripping) and routine group (63 cases, intravenous dripping of polycolistin B alone). The differences in efficacy (mortality,clinical response rate and bacterial clearance rate)and safety (elevated serum creatinine, bronchospasm and skin pigmentation) were compared between two groups; the influential factors of primary outcome index as mortality were analyzed through univariate analysis and multivariate Logistic regression analysis. RESULTS In terms of efficacy, there were no statistical differences in mortality(37.50% vs. 41.27%, P=0.749), clinical response rate (54.17% vs. 55.56%, P=0.907) and bacterial clearance rate (45.83% vs. 44.44%, P=0.907) between the two groups. In terms of safety, the incidence of bronchospasm in the combined group was significantly higher than that of the routine group (12.50% vs. 0, P=0.028), but the differences in incidence of elevated serum creatinine and skin pigmentation between two groups were not statistically significant (P>0.05). Univariate analysis showed that the moralities were higher in the case of infected with Acinetobacter baumannii, Klebsiella pneumoniae and combined use of quinolones (P<0.05); multivariate Logistic regression analysis showed that infection with A. baumannii (OR=3.36, P=0.014) and combined use of quinolones (OR=3.54, P=0.013) were independently associated with mortality (P<0.05). CONCLUSIONS For severe pneumonia patients with mechanical ventilation, intravenous dripping of polycolistin B combined with aerosol inhalation does not show superior efficacy compared with intravenous dipping of polycolistin B alone, but significantly increases the incidence of bronchospasm. Infection with A. baumannii and combined use of quinolones are independent risk factors for the increase of mortality.
