ABSTRACT

Objective To explore the epidemic characteristics of pyogenic liver abscess (PLA) in the elderly and to screen risk factors affecting prognosis. Methods A total of 406 elderly PLA patients admitted to our hospital from April 2018 to December 2022 were selected to collect their clinical data and Microbiological culture; According to the treatment results, it is divided into improvement (Group A), deterioration or death (Group B), and logistic regression model is used to analyze the prognostic factors. Results Among the 406 patients, there were 274 males and 132 females; The common manifestation was fever in 341 cases (83.99%); The main complications were 158 cases of diabetes (38.92%), followed by 77 cases of biliary diseases (18.97%). Among 243 cases with positive Microbiological culture, 124 cases (51.03%) were Escherichia coli, followed by 46 cases (18.93%) of Pseudomonas aeruginosa. There were 258 cases in group A and 148 cases in group B. There were significant differences between the two groups in age, liver abscess diameter, diabetes, Alkaline phosphatase, lactate deaminase, Prothrombin time, total bilirubin and globulin levels (P<0.05). Age, diameter of liver abscess, Alkaline phosphatase and Prothrombin time were independent risk factors for poor prognosis (P<0.05). Conclusion The main symptoms of elderly PLA patients are fever, diabetes and other diseases. Most of the pathogenic bacteria are Escherichia coli.

ABSTRACT

Objective: To evaluate the feasibility of identification and preservation of arm lymphatics (DEPART) in axillary lymph node dissection (ALND) for breast cancer to prevent arm lymphedema. Methods: A randomized controlled study method was used. Two hundred and sixty-five patients who underwent breast cancer surgery at the Department of Thyroid and Breast Surgery, Zhongnan Hospital of Wuhan University from November 2017 to June 2018 were included, and the patients were randomly divided into ALND+ DEPART group (132 patients) and standard ALND group (133 patients) by random number table method. In the ALND+ DEPART group, indocyanine green and methylene blue were injected as tracers before surgery, and the arm sentinel nodes was visualized by staged tracing during intraoperative dissection of axillary lymph nodes. Partial frozen sections were made of arm lymph nodes >1 cm in length and hard and suspicious of metastasis, and arm lymph nodes and lymphatic vessels were selectively preserved. Patients in the standard ALND group underwent standard ALND. Objective and subjective indexes of arm lymphedema were evaluated by 5-point circumference measurement and Norman questionnaire. Results: Among 132 breast cancer patients in the ALND+ DEPART group, 121 (91.7%) completed DEPART. There were no statistically significant differences in age, body mass index, pathological type, dissection number of axillary lymph node, N stage, TNM stage, molecular typing, and regional radiotherapy between the ALND+ DEPART and standard ALND groups (P>0.05). At a median follow-up of 24 months, assessment by the 5-point circumference measurement showed that the incidence rates of lymphedema in the ALND+ DEPART and standard ALND groups were 5.0% (6/121) and 15.8% (21/133), respectively, with statistically significant differences (P=0.005). Assessment by the Norman questionnaire showed that the incidence rates of lymphedema in the ALND+ DEPART and standard ALND groups were 5.8% (7/121) and 21.8% (29/133), respectively, with a statistically significant difference (P<0.001). No local regional recurrence was observed in either group during the follow-up period. Conclusion: For breast cancer patients with positive axillary lymph nodes, the administration of DEPART during ALND can reduce or avoid the occurrence of arm lymphedema without compromising oncology safety.

ABSTRACT

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by the degeneration of upper and lower motor neurons selectively. Although the motor system lesion is the most predominant clinical manifestation of ALS, with the progression of the understanding of the pathogenesis and clinical detection of the disease, more and more patients are found to have extra-motor features of ALS, such as somatosensory involvement, etc. The research results demonstrated that ALS might be a kind of disorder combined with sensory disturbance according to the electrophysiology, neuropathology, neuroimaging, animal model simulation, genetic evidence, and other methods detected. We, herein, review the prevalence and detection methods especially the aspect of genetic associations implicated in the sensory nerve disturbance of ALS.

ABSTRACT

OBJECTIVE:To provide reference for clinical empirical treatme nt of non-fermentative Gram-negative bacilli (NFGNB)infection. METHODS :All kinds of clinical specimens were collected from Jan. 2010 to Dec. 2019 in a tertiary hospital from Hanzhong city of Shaanxi province ;the distribution and drug resistance of NFGNB were analyzed retrospectively. RESULTS : A total of 26 386 strains of pathogenic bacteria were detected in the hospital during 2010-2019,including 4 077 strains of NFGNB (15.45%),mainly from patients ≥60 years old (1 836 strains,45.05%). During the 10 years,the detection rate of NFGNB decreased from 20.14% in 2010 to 15.36% in 2019 (P<0.001). Acinetobacter baumannii (1 359 strains),Pseudomonas aeruginosa (1 269 strains),Stenotrophomonas maltophilia (447 strains) and Burkholderia cepacia (351 strains) were main pathogens. The detected NFGNB mainly came from hospitalized patients (4 001 strains),and most of them were found in ICU (17.05%),neurosurgery department (14.52%),respiratory department (12.41%),and respiratory tract (66.69%),secretion (7.80%)specimens. The detection rates of A. baumannii and P. aeruginosa in oncology department ,blood specimens and urine specimens showed an overall upward trend ,while the detection rates in ICU of the hospital showed a downward trend (P<0.05); the detection rate of P. aeruginosa in neurosurgery department showed an upward trend (P<0.05),and that of A. baumannii in respiratory department showed an upward trend (P<0.05). The resistance rate of A. baumannii to carbapenems increased from about 10% in 2010 to about 75% in 2019,and the guyh3201@163.com resistance rate to cephalosporins exceeded 78%. The resistance rates of P. aeruginosa to imipenem and me ropenem were lower than 35% and 30% respectively,and the trend of drug resistance did not change significantly (P>0.05);the resistance rates to 12 kinds of clinically commonly used antibiotics as piperacillin and aztreonam were lower than 40%. The resistance rate of S. maltophilia to compound sulfamethoxazole showed a decreasing trend (P<0.001),and the resistance rate to ceftazidime was high (54.70%-74.10%). The resistance rates of B. cepacia to compound sulfamethoxazole,meropenem and ceftazidime showed a downward trend (P<0.01),and were lower than 15% after 2014. CONCLUSIONS:Although the detection rate of NFGNB in our hospital showed a downward trend ,the multi-drug resistance and pan-drug resistance of A. baumannii are serious ,and the resistance rate to carbapenems is increased. Sensitive drugs such as cefoperazone/sulbactam,amikacin,levofloxacin and ceftazidime should be selected for NFGNB infection according to the results of drug sensitivity tests.

ABSTRACT

To explore the regularity of traditional Chinese patent medicines for the treatment of hyperlipidemia recorded in Newly Edited National Chinese Traditional Patent Medicines,the Composition Principles of Chinese Patent Drugs,New Drug Conversion Standard,the Compilation of National Standard for Traditional Chinese Medicines and Chinese Pharmacopoeia. Researchers extracted the information of prescriptions from these cases according to the inclusion and exclusion criteria. Then microsoft excel 2010 was used to conduct frequency statistics and count the frequency of traditional Chinese medicine. SPSS Clementine( ver.12. 0) and SPSS( ver. 18. 0)were adopted respectively for frequency analysis,association rules analysis,cluster analysis and factor analysis. Besides,KMO test and Bartlett spherical test were performed for factor adaptation test. Finally,a total of 173 traditional Chinese medicines were included,involving 94 Chinese patent medicine prescriptions. The frequency results of traditional Chinese medicine showed that there were 33 kinds of high-frequency traditional Chinese medicine,mainly including those for tonifying medicine,activating blood and resolving stasis and blood-stasis,and clearing damp. The association rules analysis found out 12 association rules of drug pairs,3-herb pairs of 25 and4-herb pairs of 6. Totally 11 medicine groups with relevance were respectively extracted by cluster analysis. KMO test and Bartlett spherical test indicated that the method was suitable for factor analysis and 11 common factors were respectively extracted by factor analysis. The association rules reflected the therapeutic method for tonify the liver and kidney,activating blood and resolving stasis. Cluster analysis and factor analysis showed the therapeutic method of Qi-enriching and Yin-nourishing,and the factor analysis focused more on removing blood stasis and dampness. The decision tree with hawthorn as the dependent variable reflects the importance of alisma orientalis and fructus schisandrae in the drug matching. In conclusion,data mining technique can comprehensively analyze the regularity of prescriptions of traditional Chinese patent medicine for hyperlipidemia,and is helpful for guiding the development of Chinese patent medicines and the clinical practice of traditional Chinese medicine.

ABSTRACT

Objective To collect the laboratory parameters and clinical parameters of blood culture positive samples,and analyze the composition and laboratory characteristics of real pathogens by combining with clinical follow-up and anti-infectious treatment outcomes.Methods We conducted a prospective study to isolate the 483 strains of pathogens from 4313 cases of blood samples for clinical examination between March 2013 and March 2015.The results of laboratory and clinical infections were collected for each positive culture and were followed up for clinical follow-up to understand the responsible doctors' experience-based judgment and targeted clinical treatment of antibiotics.After comprehensive analysis we determined the real pathogens and contaminants.Results Of the 483 positive cultures,331 were finally determined as pathogenic ones,accounting for 68.5% of the number of positive isolates; 97 were contaminated bacteria (20.1%); and 55 strains with uncertain pathogenic nature (11.4%).Escherichia coli accounted for the highest proportion (41.2%)of pathogenic bacteria.Coagulase-negative staphylococci took up the highest proportion (75.3%)of the contaminated bacteria.As many as 253 strains (52.4%)were detected from the aerobic or anaerobic bottles.The detection rate of Escherichia coli in anaerobic bottles (23.9%)was higher than that in aerobic bottles (13.8%)(P <0.05).Of 97 strains of positive isolates,only one bottle was reported positive for 90 strains,accounting for (92.8%),and more than two bottles of 7 positive strains,accounting for (7.2%)(P <0.05).34 positive in 24 h (35.1%),77 positive in 48 h (79.4%),the positivebacteria ratio within 48 h (79.4%)was higher than that of bacteria contamination ratio within 24 h (χ2 =38.935, P =0.000),with a significant difference.Conclusion Establishment of contaminated bacteria in blood culture cannot rely solely on laboratory or clinical parameters.It should be combined with the experience of clinicians to determine the clinical response to comprehensive judgments.For the laboratory to determine the presence of contamination,the number of positive bottles and the amount of sun are still two factors of important value.Paying attention to inspection of anaerobic bottles is more conducive to the detection of Escherichia coli.

ABSTRACT

Multiple system atrophy (MSA) is a progressive neurodegenerative disorder. Widespread presence of glial cytoplasmic inclusions is the neuropathologic hallmark of MSA. The disease has long been considered as a sporadic disorder. However, in recent years, a few familial cases of MSA have been reported, and researches have verified certain genetic variants could increase the risk of MSA. These indicated genetic factors may play an imported role in the pathogenesis of MSA. In this review, the emerging evidence in favor of genetic players in MSA is discussed.
