RESUMEN
Objective To investigate the risk factors of infection of Pseudomonas aeruginosa combined with Elizabethkingia anophelis in patients with cerebral hemorrhage and the antimicrobial treatment plan. Methods Clinical pharmacists participated in the treatment of pulmonary infection caused by Pseudomonas aeruginosa combined with Elizabethkingia anophelis in a patient with cerebral hemorrhage. The risk factors of Elizabethkingia anophelis infection and antimicrobial treatment plan were analyzed by referring to literature and combining the patient’s condition, medical history, drug use history and related examination results. Results Based on the infection site, the characteristics of mixed bacterial infection, and the metabolic/pharmacodynamic characteristics of antimicrobial agents, clinical pharmacists made drug recommendations for clinicians in the adjustment of anti-infection protocols, and patients’ systemic infections were effectively controlled. Conclusion Elizabethkingia anophelis is a conditional pathogen with low virulence and is not easy to infect healthy people. When the patient's immunity is low, it is easy to transform into pathogenic bacteria, which should be paid attention to.
RESUMEN
Objective To study the activity of ten kinds of antipyretic-antidotal traditional Chinese medicine(TCM),including radix tinosporae.herb of blin conyza and turmeric,against extensively drug-resistant Acineto-bacter baumannii(XDR-AB)infection,screen out the extracts of antipyretic-antidotal TCM which have in vivo anti-infection activity,provide a research basis for the discovery of novel antimicrobials against XD-RAB infection.Methods Ten antipyretic-antidotal TCM were extracted with water,50%ethanol and 95%ethanol respectively,and TCM extracts with different concentrations were prepared,which were co-incubated with the model of XDR-AB-infected Caenorhabditis elegans previously optimized by the research group.The in vivo activity of antipyretic-antidotal TCM against XDR-AB infection was judged through the survival rate of Caenorhabditis elegans.Results With the increase of concentration of turmeric and cortex pseudolaricis extracts,the survival rate of XDR-AB-infec-ted nematodes continued to improve.The water extract,50%ethanol extract,and 95%ethanol extract of turmeric at a concentration of 1 000 μg/mL could increase the survival rates of XDR-AB-infected Caenorhabditis elegans to 54.2%(compared to the negative control group,P<0.001),18.8%,and 13.3%,respectively.The water ex-tract,50%ethanol extract,and 95%ethanol extract of cortex pseudolaricis at a concentration of 1 000 μg/mL could increase the survival rates of XDR-AB-infected Caenorhabditis elegans to 47.4%(compared to the negative control group,P<0.001),23.8%,and 15.8%,respectively.Conclusion The water extracts of turmeric and cortex pseudolaricis have good activity against XDR-AB infection,and their main chemical components can be tested for in vitro antimicrobial efficacy to discover novel antimicrobial agents against XDR-AB infection.
RESUMEN
OBJECTIVE To explore the way to re-use epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) in patients with EGFR-TKI-induced interstitial pneumonia (IP), using osimertinib as an example. METHODS The IP treatment regimen and re-use of EGFR-TKI regimen in a patient who developed IP after the use of osimertinib were analyzed. And a literature review was made by combining the characteristics of the cases which reported in the literature and the characteristics of this case. RESULTS The patient’s IP symptoms due to treatment with osimertinib had resolved after treatment. The patient’s IP symptoms also did not worsen after using almonertinib in combination with hormones as re-use of EGFR-TKI regimen. However, almonertinib was discontinued as the patient experienced disease progression. The adverse reactions of IP needed to be dealt with in time, the EGFR-TKI should be discontinued and symptomatic treatment should be given. CONCLUSIONS EGFR-TKI targeted therapy could be re-selected by replacing EGFR-TKI, adjusting the dose of EGFR-TKI, and using hormones in combination. EGFR-TKI-induced adverse drug reactions of IP are rare, but need to be observed closely. If other EGFR-TKI is used, close monitoring of adverse reactions and curative effects are also required in order to adjust the patient’s treatment plan in time.
RESUMEN
OBJECTIVE To systematically evaluate the safety of paroxetine in the treatment of pregnant patients with depression in the second and third trimesters of pregnancy, and provide reference for rational clinical use of it. METHODS Retrieved from Cochrane Library, PubMed, Embase, VIP, CNKI, Wanfang database and SinoMed database, by manual search, randomized controlled studies or observational studies were collected on depression patients who were given paroxetine vs. selective serotonin reuptake inhibitor (SSRI) in the second and third trimesters of pregnancy during the inception to Aug. 2022. Methodological qualities of the included studies were assessed by Cochrane Handbook 5.1.0 or Newcastle-Ottawa Scale (NOS). Meta-analysis was performed with RevMan 5.4.1 software. RESULTS Finally, 9 observational studies were included, and all included studies were of high quality in NOS scale. Meta-analysis was performed on 8 cohort studies. Meta-analysis showed that the total incidence of adverse pregnancy outcomes of mothers and infants [RR=0.99, 95%CI(0.89,1.10),P=0.87], total incidence of maternal adverse pregnancy outcomes [RR=0.98, 95%CI (0.87,1.10), P=0.69] and premature birth [RR=0.89, 95%CI (0.43, 1.83), P=0.75] in the second and third trimesters of pregnancy were lower than that with other SSRI, without statistical significance. The incidence of neonatal complications with paroxetine in the second and third trimesters of pregnancy was higher than that with other SSRI, but the difference was not statistically significant [RR=1.02, 95%CI (0.82,1.29), P=0.84]. One study reported that the incidence of neonatal pulmonary hypertension in paroxetine group was higher than that in other SSRI group (0.4% vs. 0.3%). CONCLUSIONS The safety of peroxetine in the second and third trimesters of pregnancy is comparable with that of other SSRI, but it is necessary to be alert to the occurrence of neonatal pulmonary hypertension.

Patient-derived tumor organoids (PDOs) currently represent important modeling tools in pre-clinical investigation of malignancies. Organoid cultures conserve the genetic and phenotypic characteristics of the original tumor and maintain its heterogeneity, allowing their application in many research fields. PDOs derived from colorectal cancer (CRC) have been used for genetic modeling to investigate the function of driver genes. Some researchers have been exploring the value of CRC PDOs in chemotherapy, targeted therapy, and radiotherapy response prediction. The successful generation of PDOs derived from CRC could deepen our understanding of CRC biology and provide novel tools for cancer modeling, for realizing precision medicine by assessing specimens from individual patients ex vivo. The present review discusses recently reported advances in CRC PDOs and the challenges they face as pre-clinical models in CRC research.
RESUMEN
OBJECTIVE@#To explore the risk factors of osteonecrosis of femoral head after internal fixation of femoral neck fracture in young patients, to describe the quality of life of patients with surviving femoral head, and to quantify the predictive factors.@*METHODS@#From January 2013 to December 2016, 172 patients (174 hips) with femoral neck fracture treated by closed reduction and cannulated screw internal fixation were selected for retrospective analysis. The general data of the patients were summarized, including age, gender, body mass index, trauma mechanism, trauma operation interval, trauma season and whether the internal fixation was removed. The imaging data included the Garden classification and Pauwel classification of fractures, femoral head retroversion angle, postoperative fracture reduction, screw distribution. Single factor analysis and multi-factor Logistic regression analysis were carried out to explore the risk factors of femoral head necrosis and internal fixation failure. The patients who survived the internal fixation were followed up. The quality of life of the patients was evaluated by the health survey of SF-36. The Harris score of hip joint function was used to evaluate the hip joint function. The predictors of the quality of life of the patients after the operation of femoral neck fracture were analyzed by multiple linear regression analysis.@*RESULTS@#Total 172 patients(174 hips) were included in the study, 29 patients(16.67%) had necrosis of the femoral head. In multivariate Logistic regression analysis, the significant differences were reduction quality (=0.126, =0.027) and posterior inclination angle (=4.380, =0.010). One hundred and thirty six patients (137 hips) who survived the femoral head were included in the quality of life survey. Harris score was 90.14±7.92, including excellent 96 hips (70.07%), good 28 hips (20.44%), medium 13 hips (9.49%) and poor 0 hip. In SF-36 score, physical health summary (PCS) was 46.12±9.12, mental health summary(MCS) was 50.21±3.97, there was no linear correlation between them (>0.05). In multiple linear regression analysis, the variables with significant difference in PCS were reduction quality and retroversion angle, and the variables with significant difference in MCS were fracture displacement and trauma mechanism.@*CONCLUSION@#Poor reduction quality and posterior inclination angle>15° are the risk factors of femoral head necrosis. The function of hip joint and MCS of patients with femoral neck fracture recovered well, but PCS could not recover to the average level of normal people. The reduction quality and retroversion angle could be used as the predictors of PCS, and the displacement and trauma mechanism of fracture could be used as the predictors of MCS.

RESUMEN
BACKGROUND: Percutaneous kyphoplasty (PKP) and percutaneous vertebroplasty (PVP) have been shown to obtain satisfactory clinical efficacy in the treatment of spinal sandwich fracture compared with conventional conservative method, but a further investigation on the related biomechanical characteristics is required. OBJECTIVE: To compare the biomechanics characteristics of PVP and PKP for spinal sandwich fracture. METHODS: The finite element models of PVP and PKP were constructed based on the finite element model of spinal sandwich fracture. The deformation and stress distribution characteristics were analyzed after loaded. RESULTS AND CONCLUSION: After PVP for L1, T11sandwich fracture, the stiffness at the thoracic and lumbar segments, the maximum stress and deformation at the sandwich vertebrae showed no obvious improvement, and the stress concentration at the anterior column of sandwich vertebrae was not improved significantly (from 26.12 Mpa to 23.37 Mpa, reduced by 10.53%). Meanwhile, PKP significantly increased the stiffness at the thoracic and lumbar segments, the maximum stress and deformation of the sandwich vertebrae were significantly decreased (from 27.15 Mpa to 17.52 Mpa, reduced by 36.71%).
RESUMEN
To clarify the effect of the sympathetic nerves on the body's physiopathological changes and acupuncture effect by the alphal-AR mediation in the past 30 years.The paper has referred to the database of CNKI and Pubmed,and systematically reviewed the publications in the past 30 years about the research of the alphal-AR mediation of the sympathetic nerves to the body's physiological andpathological changes and acupuncture effect.Alphal-AR not only mediated the sympathetic nerves on the inotropic change of the heart,and the contraction of the vascular smooth muscles,bladder sphincter,and uterine smooth muscles and other physiological effect,but also mediated cardiac arrhythmia,myocardial hypertrophy and other pathological process.In addition,Alphal-AR also mediated the acupuncture signal transmission,and acupuncture was able to adjust the sympathetic nervous tension.The body's physiopathological changes are closely related to alpha1-AR and subtype alteration.The in-depth study of alphal-AR helps to explain physiopathological mechanism of the body,as well as provide theoretical basis and the corresponding pharmacological models for better selective drugs.Studying Alpha1-AR on meridians contributes to the discovery of meridian essence and the substantial basis of acupuncture effects.
RESUMEN
Objective To observe over-time changes in rat blood flow in the skins of related meridian points during physiological status, the pathological state of ischemic myocardial injury and low or high frequency electroacupuncture intervention and explore the post effect of different frequency electroacupuncture on related meridian points after treating ischemic myocardial injury. Method Fifty male Wister rats were randomized into five groups: blank control, sham operation, model, low frequency electroacupuncture (meridian point A) and high frequency electroacupuncture (meridian point B), 10 rats each. Blood flow in the skins of bilateral points Neiguan (PC6), Ximen (PC4) and Tianquan (PC2), and non-meridian and non-acupoint control points was measured by laser speckle contrast imaging in every group immediately and at 30 and 60 min after the end of three treatments. Statistical analysis was made. Result Blood flow in the skins of bilateral points Neiguan, Ximen and Tianquan was significantly lower in the blank control group than in the model group (P<0.01,P<0.05). Blood flow in the skin of every acupoint increased in varing degrees after low or high frequency electroacupuncture treatment. Blood flow in bilateral points Neiguan, Ximen and Tianquan regions in meridian point group A was closer to that in the blank control group immediately after treatment. Blood flow in three left-side and three right-side acupoint regions in meridian point group B was closer to that in the blank control group at 30 and 60 min, respectively, after treatment. Conclusion The immediate effect of low frequency electroacupuncture on blood flow in acupoint regions is better than high frequency electroacupuncture during intervention in ischemic myocardial injury. The post effect of high frequency electroacupuncture on blood flow in acupoint regions is better than low frequency electroacupuncture during intervention in ischemic myocardial injury.
RESUMEN
Objective To observe the analgesic effect of acupuncture at Guanyuan (CV4) and its effect on vasomotor substances in rats with dysmenorrhea due to coagulated cold syndrome. Method The coagulated-cold dysmenorrhea rat model was developed by Estrodiol benzoate and Oxytocin injectin plus physical freezing. The writhing response (writhing latency, writhing frequency, and writhing score) was observed, and the contents of TXB2 and 6-keto-PGF1a were detected by using enzyme-linked immunosorbent assay (ELISA). Result Compared with the saline water group, the writhing latency was significantly shortened, the writhing frequency was significantly increased, and the writhing score was more significantly increased in the model group (P0.05) in the model group. Compared with the model group, the content of plasma 6-keto-PGF1a showed an increasing tendency (P>0.05) and the content of plasma TXB2 showed a decreasing tendency (P>0.05) in the acupuncture group. Conclusion The vasomotor substances are obviously disordered in the blood of cold-coagulated dysmenorrhea rat models. Acupuncture at Guanyuan can improve the writhing response and release pain, and meanwhile positively regulate the vasomotor substances such as TXB2 and 6-keto-PGF1a. The vasomotor substances are plausibly one of the major substances in the action of acupuncture in preventing and treating dysmenorrhea.

Compared with the tail-suspension group, the content of ACTH in hypothalamus was significantly decreased (P< 0.05) in the EA at "Neiguan" (PC 6) group; the content of CRH, ACTH and CORT was significantly decreased (P < 0.01, P < 0.05) in the EA at "Sanyinjiao" (SP 6) group. Compared with the EA at "Neiguan" (PC 6) group, the content of CORT was decreased (P < 0.05) in the EA at "Sanyinjiao" (SP 6) group.</p><p><b>CONCLUSION</b>EA can regulate the content of 5-HT in hypothalamus in tail-suspension rats, inhibit the hyperactivity of the HPA axis, in which EA at "Sanyinjiao" (SP 6) had more significant effects than "Neiguan" (PC 6), but no obvious effects on NE and DA were observed.</p>

OBJECTIVE@#To study the effect of low intensity pulsed ultrasound (LIPUS) on the expression of tissue inhibitor of metalloproteinase-2 (TIMP-2) in the serum and expression of matrix metallopeptidase 13 (MMP-13) in the articular cartilage cells of rabbits with knee osteoarthritis (OA).@*METHODS@#Inner patellar ligament defect method was used to establish the model of knee OA. Four weeks after the modeling, the arterial blood was drawn from the ear of each rabbit, while ELISA was employed to detect the expression of TIMP-2 in the serum. The chondrocytes were separated from animals in each group and then cultured in vitro. All rabbits were divided into control group, OA model group and OA + LIPUS group. Cells in the control and OA groups were not treated, while cells in the OA + LIPUS group were treated with LIPUS (40 mW/cm(2), 1 time/day). Cells were collected 7 d later and the RNA and total protein were extracted respectively. Real-time PCR and Western blotting were employed to analyze the expression of MMP-13 in chondrocytes at the mRNA and protein level, respectively.@*RESULTS@#The success rate of establishment of OA model was 83%. The results of ELISA showed that the content of TIMP-2 in the serum of animals with OA was 22.3%, lower than the one in the control group (P < 0.05). Compared with the normal control group, the expression of TIMP-2 in the OA model group was significantly increased, while the expression of MMP-13 was significantly increased (P < 0.05). After the stimulation of LIPUS, the expression of TIMP-2 and MMP-13 was close to the one in the normal control group.@*CONCLUSIONS@#The inner patellar ligament defect method is a mature method to establish the rabbit OA model, with high success rate. The expression of serum TIMP-2 in the OA model group is significantly decreased. LIPUS can up-regulate TIMP-2 and down-regulate MMP-13.
