ABSTRACT

Objective@#To explore the clinical and radiological features of myelin oligodendrocyte glycoprotein (MOG) antibody associated disease.@*Methods@#The clinical data of 22 MOG antibody associated disease cases treated in the Department of Neurology, Qilu Hospital of Shandong University from January 2017 to June 2019 were retrospectively analyzed. The clinical data of MOG antibody associated disease were summarized, including clinical and imaging features.@*Results@#Of the 22 included patients with MOG antibody associated disease, the average age was 38.5 years, 13 were male and nine were female. Among them, 11 cases manifested as aquaporin-4 (AQP4)-negative neuromyelitis optica spectrum disorder (NMOSD), four cases optic neuritis, two cases transverse myelitis, one case acute disseminated encephalomyelitis (ADEM), two cases cortical encephalitis and two cases vestibular neuronitis. Magnetic resonance imaging (MRI) results showed that multiple anatomical areas were involved. Among the nine patients with optic nerve involvement, five patients had longitudinally extensive optic nerve lesions, which were longitudinally enhanced. In eight patients, MRI lesions in the spinal cord showed mostly long or short segments involvement, involving 2-5 spinal cord segments. Five cases involved the cervical spinal cord, six cases involved the thoracic spinal cord, and one case involved the lumbar spinal cord. Brain MRI abnormalities were found in 13 cases and the lesions were mostly patchy and point-shaped. MRI lesions demonstrated T2 hyperintensity and some of them could be strengthened, which may involve the basal ganglia, thalamus, radiographic crown, frontal temporal lobe, brain stem and other parts. Among them, 16 patients were sensitive to high-dose intravenous/oral methylprednisolone in the acute phase. Seven patients had recurrence after two months to two years of follow-up.@*Conclusions@#MOG antibody associated disease include multiple manifestations. Among them, AQP4-negative NMOSD is the most common form. The clinical manifestations of patients showed diversity. Imaging is characterized by multiple parts involvement such as optic nerve, spinal cord, and brain. Most patients are sensitive to high-dose intravenous/oral methylprednisolone, and have a good prognosis in the acute phase, but some patients may relapse.

ABSTRACT

Objective:To investigate the effects of long-chain non coding RNA (lncRNA) XIST on the proliferation and migration of pancreatic cancer PANC1 cells, and clarify the targeting relationship between lncRNA XIST and miR-101/enhancer of zeste homologz(EZH2).Methods:Ninety cases of pancreatic cancer surgically resected and pathologically confirmed in the first hospital of Jiaxing city from July 2010 to September 2018 and its corresponding paracarcinoma normal tissue were collected. PANC1 cells were divided into sh-XIST group, SH control group, MiR control group and miR-101 group. The expression of LncRNA XIST and miR-101 in pancreatic cancer tissue and PANC1 cells in each group were detected by fluorescence quantitative PCR. The relationship between the expression of LncRNA XIST and miR-101 and the clinicopathological parameters of tumor was analyzed. The proliferation and migration ability of PANC1 cells in each group were analyzed by CCK8 method and transwell chamber test. The EZH2 expression level of PANC1 cells in each group were analyzed by western blot. PANC1 cells in each group was inoculated into BALB/C nude mice with a cell density of 3×10 6 cells/100 μl and the tumor volume was measured. The relationship between LncRNA XIST and its miR-101 and targeting gene EZH2 were analyzed by bioinformatics and double luciferase reporter genes. Results:Compared with the paracancerous tissues, the level of LncRNA XIST in pancreatic cancer tissue was significantly increased 2.89±0.42 vs (1.12±0.22, P<0.05), and the level of miR-101 was significantly decreased 0.32±0.12 vs (1.25±0.22, P<0.05), and the differences were statistically significant ( P<0.05). LncRNA XIST expression in pancreatic cancer tissue was obviously increased along with higher differentiation degree, advanced TNM stage and lymph node metastasis, while miR-101 was greatly decreased. Compared with the cells in the sh-control group, the expression level of LncRNA XIST in the sh-XIST group was significantly decreased (0.34±0.18 vs 1.21±0.27). Compared with miR-control cells, the level of miR-101 cells in miR-101 group significantly increased (2.94±0.31 vs 1.54±0.29 ), and the differences were statistically significant ( P<0.05). After 72 h cell culture, the light absorption value at 450 nm in sh-control group, sh-XIST group, miR-control group and miR-101 group was 1.98±0.24, 1.21±0.20, 1.87±0.21 and 1.11±0.17; the number of transmembrane cells were (74.25±6.79 ), (29.11±5.17), (61.27±5.19) and (20.47±4.58)per 200 times visual field; the cell proliferation activity and migration ability in sh-XIST group were significantly decreased than sh-control group, miR-101 group and miR-control group and the xenograft tumor grew obviously slowly, all the differences were statistically significant (all P<0.05). Conclusions:LncRNA XIST can target miR-101/EZH2, regulating the proliferation and migration of pancreatic cancer cells, which promotes the occurrence and development of pancreatic cancer.

ABSTRACT

Krüppel-like factors (KLFs) play extremely important roles in genesis and development of tumors. Simultaneously, KLFs have been proven to affect the proliferation, differentiation and migration of hepatocellular carcinoma cells. Nine members in the KLFs family (KLF2, KLF4, KLF5, KLF6, KLF8, KLF9, KLF10, KLF14 and KLF17) are involved in the occurrence and development of hepatocellular carcinoma in various ways as an oncogene and tumor suppressor gene. Therefore, the KLFs family will hopefully become biological therapeutic targets for hepatocellular carcinoma.

ABSTRACT

Objective:To investigate the clinical features, imaging features, gene diagnosis, treatment and prognosis of autosomal dominant lateral temporal epilepsy (ADLTE) with heterozygous RELN mutation.Methods:Clinical data of an ADLTE family caused by a heterozygous mutation in the RELN gene diagnosed in September 2019 at Qilu Hospital of Shandong University were collected. The clinical characteristics of ADLTE were analyzed, and literature review was conducted.Results:The male proband, 22 years old, was admitted with the clinical manifestations including seizures begun at temporal lobe, which specifically manifested as a sudden emergence of binaural hum, lasting for more than 10 seconds, and the symptoms can self-recover quickly. Half a month later, generalized tonic-clonic seizures attacked subsequently after a similar auditory aura. There were no abnormal findings in interictal electroencephalography (EEG) and magnetic resonance imaging (MRI). Following the family history, his father had similar auditory symptoms around the age of 20, and occasional secondarily generalized tonic-clonic seizures appeared. Antiepileptic drug can control better. The whole exome sequencing of three people in the family revealed that both the proband and his father had NM-005045: c.6068T>C heterozygous mutation in the RELN gene.Conclusions:ADLTE mostly occurs in juveniles or early adulthood. The main clinical manifestations are focal seizures with auditory auras, which can be followed by generalized tonic-clonic seizures. There are no abnormal findings in the interictal EEG and MRI. ADLTE is sensitive to drug treatment and has good clinical prognosis. The study identified a novel heterozygous mutation NM-005045: c.6068T>C in RELN gene, which is responsible for the development of ADLTE.

ABSTRACT

Leishmaniasis is a prevalent cause of death and animal morbidity in underdeveloped countries of endemic area. However, there is few vaccine and effective drugs. Antimicrobial peptides are involved in the innate immune response in many organisms and are being developed as novel drugs against parasitic infections. In the present study, we synthesized a 5-amino acid peptide REDLK, which mutated the C-terminus of Pseudomonas exotoxin, to identify its effect on the Leishmania tarentolae. Promastigotes were incubated with different concentration of REDLK peptide, and the viability of parasite was assessed using MTT and Trypan blue dye. Morphologic damage of Leishmania was analyzed by light and electron microscopy. Cellular apoptosis was observed using the annexin V-FITC/PI apoptosis detection kit, mitochondrial membrane potential assay kit and flow cytometry. Our results showed that Leishmania tarentolae was susceptible to REDLK in a dose-dependent manner, disrupt the surface membrane integrity and caused parasite apoptosis. In our study, we demonstrated the leishmanicidal activity of an antimicrobial peptide REDLK from Pseudomonas aeruginosa against Leishmania tarentolae in vitro and present a foundation for further research of anti-leishmanial drugs.

ABSTRACT

OBJECTIVE: To explore the role of clinical pharmacist in individualized treatment for osteosarcoma patients with periprosthetic joint infection (PJI). METHODS: An osteosarcoma patient was admitted to our hospital and then suffered from PJI after operation. Clinical pharmacist adjusted the initial anti-infection plan and carried out pharmaceutical care according to the results of patients’ etiology and drug sensitivity. According to the PK-PD principle, combined with the therapeutic drug monitoring (TDM), the dose of antibiotics was adjusted. With the occurrence of ADR, the antibiotic therapeutic regimen was adjusted again. RESULTS: The patient was administrated cefotiam for empiric therapy initially after the diagnosis of PJI. After obtaining the results of etiology and drug sensitivity, the clinical pharmacist suggested that vancomycin sensitive to penicillin-resistant Staphylococcus epidermidis should be used for targeted anti-infection treatment. After adjusting the dosage according to the steady-state valley concentration, the patient had slight liver function damage, accompanied with chest tightness and shortness of breath. After analysis, the clinical pharmacist considered the adverse drug reactions related to vancomycin, and again suggested that the patient should be treated with teicoplanin. After the doctor adopted the treatment plan recommended by the clinical pharmacist, PJI of the patient was effectively controlled, and the adverse reaction symptoms disappeared. The patient was effectively cured for PJI and discharged eventually. During the treatment period, the clinical pharmacist also carried out medication education for the drugs used by the patient. CONCLUSIONS: Clinical pharmacist should master the principle of antibiotic drug PK-PD theory and evaluate the clinical efficacy and safety of anti-infective drugs dynamically based on the guidance of TDM, so as to develop individualized anti-infection therapeutic regimen for osteosarcoma patient with PJI, improve the effect of clinical treatment and guarantee the safety of drug use.

ABSTRACT

The narrow therapeutic index, non-linear pharmacokinetics and unpredictable absorption require regular therapeutic monitoring of phenytoin. The influence of genetic differences, sex,age and race on the phenytoin plasma levels and its metabolites is well recognized. This study is aimed at evaluating phenytoin plasma drug concentration and its relationship with clinicalrespone, persistent seizures and toxicity in different gender and various age group of Chinese epileptic patients. This knowledge will help the clinicians in adjusting the drug dosages of phenytoin in various sub-groups of epileptic patients for enhancing the safety. efficacy and minimizing the toxicity of phenytoin. A total of 48 plasma samples of epileptic patients for measuring the olasma phenytoin concentration were received. Only patients displaying persistent seizures or suspected adverse effects were requested for drug monitoring. All these samples were analyzed for therapeutic drug monitoring with Enzyme-multiplied immunoassay technique. Suprisingly, it was found that majorities [85.5%] of samples were out of the reference range, of which 69% of samples were in sub-therapeutic levels and 16.5% of samples were above therapeutic levels. Only 14.5% of all samples had phenytoin levels in the therapeutic range. The difference in plasma concentration of phenytoin was notably altered in gender and various age groups. Careful attention must be applied to specific gender and particular age group on an individual basis in the interpretation of plasma concentration results, in order to facilitate the modification of doses and develop the best approach in treatment and to obtain the desired clinical response because multiple factors can effect the phenytoin plasma concentration. Through these results, it can be concluded that a good correlation exists between phenytoin plasma concentration and clinical response. Therefore, regular therapeutic monitoring of phenytoin and screening of HLA-A, B,C and DRB1 genotypes before prescribing phenytoin in epileptic patients is essentially required to achieve maximum clinical response and prevent the serious toxicity

ABSTRACT

The unpredictable and unfavorable connection of dose and plasma concentration of valproic acis supports the nescessity to regularly measure its plasma concentration. The present study is drug monitoring of valproic acid and comparative evaluation of therapeutic monitoring results of valproic acid for assessment of clinical response, safety and toxicity in different age and gender groups of Chinese epileptic patients. This knowledge will help the clinicians in adjusting the drug dosages of valproic acid in various sub-groups of epileptic patients for enhancing the safety and minimizing the toxicity of valproic acid. A total of 206 plasma samples [126 males and 80 females] of epileptic patients using valproic acid were requested for therapeutic drug monitoring by neurology department of Qilu Hospital. It was found that 29% of the total samples were found in sub-therapeutic levels. 13% of the samples had toxic levels and 58% of all samples had valproic acid levels in therapeutic range. The difference in plasma concentration of valproiv acid is notably altered in gender and various age groups. However, this requires further investigation. Despite the majority of samples in the therapeutic range, there was an unfavorable clinical response. The outcomes of the current research work exposed that there was a poor correlation between the plasma concentration and clinical response. Careful attention must be applied to specific gender and particular age group on an individual basis in the interpretation of plasma concentration results, in order to facilitate the modification of doses and develop the best approach in treatment and to obtain the desired clinical response because multiple factors can effect the valproic acid plasma concentration. Through these results, it can be concluded that poor correlation exists between valproic acid plasma concentration and clinical response

ABSTRACT

Objective To investigate the value of laparoscopy in comprehensive early ovarian cancer staging by comparing the feasibility and safety of laparoscopy and laparotomy in surgical staging of early-stage epithelial ovarian cancer (EOC). Methods A total of 102 patients with EOC who underwent comprehensive laparoscopic (LPS group, n=71) or laparotomic (LPT group, n=31) staging at Southwest Hospital from November 2007 to November 2014 were retrospectively analyzed. The perioperative parameters, postoperative complication rate and the long-term curative effect were compared between the two groups. Results (1)LPS group had less intra-operative blood loss [(288±239) vs (631±463) ml], lower rate of blood transfusion(14%vs 58%), larger number of pelvic dissected lymph nodes (18.1±5.6 vs 15.5± 4.6), lower vasual analogue scalescore(VAS) pain score (2.1 ± 1.6 vs 3.0 ± 1.1), shorter gastrointestinal recovery time [(2.6 ± 0.8) vs (3.5 ± 0.9) days] and shorter hospital stay [(9.9 ± 2.9) vs (11.3 ± 5.0) days] when compared with LPT group (all P0.05). (2) No significant difference was found in postoperative rate of complications [11%(8/71) vs 19%(6/31),χ2=1.192, P=0.275]. (3) No significant difference was found in recurrence rate [17%(11/66) vs 14%(4/29), χ2=0.125, P=0.724] and 5-year overall survival (86.7% vs 86.8%, P=0.874). Conclusion Compared with LPT group, there are no significance differences in recurrence rate and mortality between two groups, laparoscopic staging, which could be recommended as a choice of surgical treatment of early ovarian cancer, shows more favorable operative outcomes including minimally invasive, less intra-operative blood loss, less postoperative pain and quicker recovery.

ABSTRACT

The present study was performed to investigate the seroprevalence and risk factors for Dirofilaria immitis infection in cats from Liaoning province, northeastern China. From October 2014 to September 2016, sera of 651 cats, including 364 domestic cats and 287 feral cats (332 females and 319 males) were assessed. They were tested for the presence of D. immitis antigen using SNAP Heartworm RT test kit. In this population, the average prevalence was 4.5%. Age and rearing conditions (feral or domestic) were found to be associated with the prevalence of D. immitis. The prevalence was significantly higher in feral cats compared with domestic cats (8.4% vs 1.4%, P 0.05), but older cats (≥3 years old) showed a statistically higher prevalence compared with younger cats ( 0.05), all these results suggest that outdoor exposure time may be one of the most important factors for D. immitis prevalence in cats. Results reveal that D. immitis are prevalence in domestic and feral cats in northeastern China, which indicates that appropriate preventive measures should be taken to decrease the incidence of feline heartworm disease in Liaoning province, northeastern China.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the impact of occupational stress on serum monoamine neurotransmitters in nurses.</p><p><b>METHODS</b>A total of 131 nurses were included as study subjects by stratified cluster sampling. The occupational health information collection system (based on the Internet of things) was used to measure occupational stress. Serum levels of monoamine neurotransmitters were also measured.</p><p><b>RESULTS</b>Epinephrine (E) was negatively correlated with superior support (P < 0.05) and colleague support (P < 0.05). Negative correlation was also found between dopamine (DA) and job prospect (P < 0.05). Level of 5-hydroxytryptamine was negatively correlated with promotion opportunities (P < 0.05). Norepinephrine (NE), E, and DA were all negatively correlated with work satisfaction (P < 0.05) and positively correlated with daily stress (P < 0.01). NE and E were negatively correlated with sufficient confidence (P < 0.05) and positively correlated with physical complaints (P < 0.01). There was a negative correlation between NE and psychological satisfaction (P < 0.05).</p><p><b>CONCLUSION</b>Occupational stress in nurses is correlated with serum monoamine neurotransmitters, and it may affect serum levels of monoamine neurotransmitters to a certain extent.</p>
