ABSTRACT
Objective:To observe the susceptibility factors of elderly patients with corynebacterium striata in sputum of lower respiratory tract and analyze its clinical therapeutic effect.Methods:The clinical data of 192 elderly inpatients infected with corynebacterium striatum detected in sputum of lower respiratory tract were retrospectively analyzed in Quanzhou First Hospital Affiliated to Fujian Medical University from January 2019 to June 2021.The detection rate of corynebacterium striata was calculated, and the susceptibility factors and clinical efficacy were compared between the infection group(n=102)and the colonization group(n=90).Results:The detection rate of corynebacterium striata(detected cases / numbers of qualified lower respiratory tract sputum specimen)was 0.8%(72/8976)from January to December 2019, 2.3%(134/5877)from January to December 2020, and 3.0%(121/4 039)from January to June 2021, the difference was statistically significant( χ2=93.93, P<0.01). The detection rates of corynebacterium striatum during three corresponding periods in elderly patients were 0.6%(57/8 976), 1.4%(81/5 877)and 1.9%(78/4 039), respectively, with statistically significant differences( χ2=45.57, P<0.01). The incidences or values of following indexes were higher in infection group than in colonization group: age of patients, admission of intensive care unit, malnutrition, use of hormones, combined use of antibiotics, use of invasive mechanical ventilation, use of fiber bronchoscope, reduced cough reflex, other basic diseases, and so on, but the differences were not statistically significant(all P>0.05). The clinical effective rates were 41.2%(42/102)in the infection group and 48.9%(44/90)in the colonization group, respectively, and the differences was not statistically significant( P>0.05). Only 25 patients(24.5%)in the infected group were treated on corynebacterium striatum according to drug sensitivity results.Among them, the clinical effective rate of the treatment group and the untreated group was 68.0%(17/25)and 32.5%(25/77), respectively, the difference was statistically significant( χ2=9.84, P<0.01). The clinical effective rate of untreated group was lower than that of colonization group, the difference was statistically significant( χ2=4.62, P<0.05). Conclusions:The detection rate of corynebacterium striatum in elderly patients is high, and increases year by year.Patients infected with corynebacterium striatum usually has a variety of susceptibility factors, if not taking effective treatment measures, may have adverse outcomes.In clinical work, it is necessary to pay attention to and reduce the susceptibility factors of corynebacterium striatum, and to correctly interpret the etiological reports, so as to adopt a reasonable and effective therapeutic schedule.

ABSTRACT
Proximal symphalangism is a rare hereditary bone disease caused by NOG or GDF5 gene mutations, of which NOG gene mutations account for the majority. A family of SYM1 was reported. Patient was a man with proximal interphalangeal joint stiffness of bilateral fingers for more than 20 years. Combined with laboratory and imaging examinations, the patient was diagnosed with proximal symphalangism. 4 other subjects in this family are affected. The detection of NOG gene mutations of the proband and his mother and son showed that there were heterozygous missense mutations in exon 1, c.667C>T, resulting in p. Pro223Ser. The pathogenesis, clinical and imaging manifestations of SYM1 were reviewed in combination with literature to improve clinicians′ understanding of the disease.

ABSTRACT
Objective To construct a model of Graves'disease ( GD ) with ( or ) Graves'ophthalmopathy ( GO) in BALB/c mice by immunization with pcDNA3. 1/TSHR289. Methods pcDNA3. 1/TSHR289 was injected into the bilateral gastrocnemius muscle of 35 model mice and electroporation was immediately performed. 10 control mice were injected with sterile saline and electroporated, while 5 blank mice were injected with sterile saline only. Each group of mice was immunized at 1, 4, 7, and 10 weeks, respectively. Serum total T4 , TSH, TSAb, and TSBAb were measured before immunization, 2 weeks after each immunization, as well as 5 and 8 weeks after the last immunization. CT scan was used to evaluate the morphological changes of the eyes of the mice.99m TcO4- imaging was used to measure the thyroid uptake function, and the pathological changes of the thyroid and orbital tissues were evaluated by HE staining. Results After the 2nd time immunization, the serum concentrations of TT4 , TSAb and TSBAb in GD mice were significantly higher than those of control and blank groups( F=13.781, 31.435, 36.112, P<0.01, respectively).The TSH continued to be significantly lower than that of control and blank groups(F=13.966, P<0.01) . After the 4th time immunizations, the ability of uptaking99m TcO4- in GD mice thyroid was significantly enhanced compared with the control group. The thyroid goiter with a large amount of lymphocyte infiltration, and the thyroid follicle was thin. CT scan of GO mice showed thickening and swelling of the extraocular muscles, and no abnormalities in tendon and muscle attachment points. HE staining showed thickening of extraocular muscle fibers, lymphocyte infiltration of extraocular muscles and orbital tissue, increased hyaluronic acid, and infiltration of fat cells. Conclusion GD or GO model can be successfully induced by multiple intramuscular injection of pcDNA3.1/TSHR289 in BALB/c mice.
ABSTRACT
Objective To analyze the clinical efficacy and safety of thalidomide combined with VAD regimen (vincristine+epirubicin+dexamethasone) or VAD regimen alone in treatment of multiple myeloma (MM) by using metaˉanalysis. Methods Thalidomide combined with VAD regimen was selected as the experimental group and VAD regimen alone was selected as the control group. The literatures were searched from CNKI, Wanfang and VIP database. And then the inclusive literatures were further searched. Randomized controlled trials eligible to the exclusive criteria were extracted, and the quality was evaluated. Metaˉanalysis was conducted by using Stata14.0 software. Results A total of 17 studies and 940 patients were included. The experimental group had a higher total effective rate compared with the control group , and the difference was statistically significant ( RR＝ 1.41, 95% CI 1.30-1.59, P< 0.01). Meanwhile, the experimental group had a better efficacy in improving hemoglobin and deducing βˉmacroglobulin (MG), M protein and myeloma cells compared with the control group; however, the experimental group also had a worse gastrointestinal reaction, and the difference was statistically significant ( RR＝ 1.36, 95% CI 1.04-1.78, P＝ 0.024). Conclusion Thalidomide combined with VAD regimen in treatment of MM has a better clinical efficacy compared with VAD regimen alone, but it also has a worse adverse reaction.
ABSTRACT
Purpose To explore the clinical pathological features and differential diagnoses and therapeutics of hyalinizing trabecular tumours ( HTT) of thyroid. Methods The clinical manifestations, high-frequency color doppler ultrasonography, histopathological and immunohistochemical features were analysed in six cases of HTT of thyroid. Related literatures were reviewed. Results On his-topathological examination, polygonal and elongated cells arranged in pattern of trabecular and organoid, with a clear perinucleolus ha-lo. Basement membrane-like material deposited intertrabeculae widespreadly. The tumour cells are completely filled with eosinophilic and granular material in their cytoplasm, nuclei with prominent grooves and pseudoinclusions. Immunohistochemically, the tumour cells were positive for TG, TTF-1 and CD56, CK19 and Galectin-3 interspersed expression. And all of them were negative for Calcito-nin, MC, CEA, Syn, CgA, Ki-67, p53 were lower expression. The differential diagnosis included solid variant of papillary carcinoma, medullary thyroid carcinoma and paraganglioma and so on. Conclusion HTT is an uncommon thyroid tumor, the majority of them be-have as benign neiplasms and that, correct pathologic diagnosis may play an important role in standard treatment and prognostic evalua-tion of HTT.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of puerarin on infarction size, fatty acids metabolism, inflammatory response and atherosclerotic plaque stability in patients with acute myocardial infarction (AMI).</p><p><b>METHODS</b>Sixty-one patients with AMI were randomly divided into two groups, the control group (n = 30) and the treated group (n = 31). All were treated with conventional treatment, but to the treated group, puerarin injection was given additionally by injecting 500 mg per day for 2 weeks. Before and after treatment, blood levels of free fatty acids (FFA), matrix metalloproteinases-9 (MMP-9) and C-reactive protein (CRP) were assayed, and the size of infarction was determined by Ideker QRS scoring method.</p><p><b>RESULTS</b>Before treatment, the size of infarction was positively correlated to the levels of FFA, MMP-9 and CRP (r = 0.43, 0.42 and 0.39, respectively, all P<0.01). As compared with those before treatment, after treatment, the three parameters lowered by 30%, 41% and 23%, respectively and the size of infarction significantly reduced in the treated group (P<0.01), while in the control group, no significant change was found (P>0.05).</p><p><b>CONCLUSION</b>Puerarin treatment could significantly reduce the size of infarction in patients with AMI, the mechanism is possibly related with its effects in lowering plasma levels of FFA, inhibiting inflammation and stabilizing atherosclerotic plaque.</p>

The effects of vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) on proliferation of bovine coronary artery endothelial cells (BCAEC) and smooth muscle cells (BCASMC) were studied in vitro. BCAEC and BCASMC were isolated and cultured and divided into control group, VEGF (50ng/ml) group and HGF (50ng/ml) group. Cells proliferation was measured using MTT method. The results showed that the OD values of control, VEGF, and HGF group in BCAEC cultures were 0.23?0.02, 0.58?0.10, and 0.42?0.12, respectively, and those in BCASMC were 0.31?0.08, 0.45?0.09, and 0.40?0.11, respectively. The proliferation ratios of BCAEC and BCASMC induced by HGF were 152.2%?33.8% and 45.2%?25.3%, respectively, and that by VEGF were 82.6%?18.7% and 29.0%?20.4%, respectively. The results suggested that HGF could promote proliferation and migration of BCAEC and BCASMC, while VEGF could promote proliferation of BCAEC but not BCASMC. The effect of HGF on BCAEC was stronger than that on BCASMC, and the induction strength of HGF was higher than VEGF.
ABSTRACT
This paper is to study the clinical characteristics of Brugada syndrome (BrS) in Chinese by analyzing clinical and ECG data of BrS patients. Data were included by computerized and manual research, and was analyzed by 2 doctors alone. The data of repetition and of non-Chinese were rejected. Forty-nine BrS patients were included (45 males and 4 females). Main manifestations included sudden death in 29 and syncope in 27 patients. Malignant ventricular arrhythmia (MVA) occurred in 14 of 17 patients with family history of sudden death or syncope and in 15 out of 32 ones without family history. Occurrence of MVA in 11 of 14 patients was within the period from 7pm to 7am. ECG revealed that sloped ST segment elevation appeared mainly in V1, V2 leads and coved ST segment elevation appeared mainly in V3 lead. BrS is not rare in Chinese people,and its clinical characteristics is similar to that overseas data.
ABSTRACT
The effects of hepatocyte growth factor(HGF) on the secretion of vascular endothelial growth factor(VEGF) in cultured bovine coronary artery endothelial cells(BCAEC), bovine coronary artery smooth muscle cells(BCASMC) and mouse cardiomyocytes were observed in vitro . The concentrations of VEGF in BCAEC control and HGF group at 12h were 10.51?2.90pg/ml and 9.31?2.78pg/ml, respectively. The concentrations of VEGF at 12h in BCASMC control and HGF group were 3.35 and 3.93 times of that at 3h respectively, the concentration of VEGF at 3h and 12h in BCASMC HGF group was 2.06 and 2.42 times respectively, of that in control group. The concentrations of VEGF at 12h in cardiomyocyte control and HGF group were 5.43 and 4.09 times, respectively, of that at 3h, and the concentrations of VEGF at 3h and 12h in cardiomyocyte HGF group was 2.74 and 2.06 times, respectively, of that in control group. These results indicated that BCAEC, BCASMC and mouse cardiomyocytes could secrete VEGF, and HGF could promote VEGF secretion in BCASMC and cardiomyocytes, but not in BCAEC.
