RESUMO

AIM: To evaluate the prevalence of coronary artery calcification (CAC) on non-contrast computed tomography (CT) of the thorax in patients with interstitial lung disease (ILD), assess consistency of CAC reporting and assess incidence of subsequent cardiac events. MATERIALS AND METHODS: Patients with known interstitial lung disease who underwent a CT thorax over a 2-year period were retrospectively reviewed. Presence of CAC was assessed using a visual scale for CAC reporting and graded as mild, moderate, or severe by two cardiothoracic radiologists. CT reports were reviewed to determine if presence of CAC had been described. Electronic medical records were reviewed for any subsequent cardiothoracic events from the date of the CT thorax to present. RESULTS: 254 patients were included in the analysis (54.7% men; mean age 59.9 yo). 43.7% had CAC on their CT thorax; however, in 87.3% of those, reports did not comment on its presence. 8 patients had cardiac events; 7 of them had CAC on CT although only in 1 case this was reported. Global CAC and LAD CAC Patients with cardiac events had a significantly higher global CAC (p=0.016) and LAD CAC (p=0.048) when compared to patients without. CONCLUSION: We demonstrated a high prevalence of CAC in ILD patients and its significant association with adverse cardiac events. Unfortunately, CAC on CT thorax is still largely unreported. As per recent BSCI/BSCCT and BSTI guidelines, reporting of CAC should become part of routine practice, as may prompt prevention and impact on patients outcome.

RESUMO

AIM: To characterise the corticoreticular pathway (CRP) in a case-control cohort of adolescent idiopathic scoliosis (AIS) patients using high-resolution slice-accelerated readout-segmented echo-planar diffusion tensor imaging (DTI) to enhance the discrimination of small brainstem nuclei in comparison to automated whole-brain volumetry and tractography and their clinical correlates. MATERIALS AND METHODS: Thirty-four participants (16 AIS patients, 18 healthy controls) underwent clinical and orthopaedic assessments and brain magnetic resonance imaging (MRI) on a 3 T MRI machine. Automated whole-brain volume-based morphometry, tract-based spatial statistics analysis, and manual CRP tractography by two independent raters were performed. Intra-rater and inter-rater agreement of DTI metrics from CRP tractography were assessed by intraclass correlation coefficient. Normalised structural brain volumes and DTI metrics were compared between groups using Student's t-tests. Linear correlation analysis between imaging parameters and clinical scores was also performed. RESULTS: AIS patients demonstrated a significantly larger pons volume compared to controls (p=0.006). Significant inter-side CRP differences in mean (p=0.02) and axial diffusivity (p=0.01) were found in patients only. Asymmetry in CRP fractional anisotropy significantly correlated with the Cobb angle (p=0.03). CONCLUSION: Relative pontine hypertrophy and asymmetry in CRP DTI metrics suggest central supranuclear inter-hemispheric imbalance in AIS, and support the role of the CRP in axial muscle tone. Longitudinal evaluation of CRP DTI metrics in the prediction of AIS progression may be clinically relevant.

RESUMO

OBJECTIVE: The standard treatment for regional failure in nasopharyngeal carcinoma (NPC) is the radical neck dissection (RND). Our study sought to determine if magnetic resonance imaging (MRI) may accurately predict nodal involvement to allow selected levels of neck dissection to be preserved. STUDY DESIGN AND SETTING: We analysed retrospectively all NPC patients in our centre undergoing neck dissections as salvage therapy for nodal recurrence. Nodal involvement based on the preoperative MRI was assessed and compared with postoperative histopathology. METHODS: This is a retrospective study conducted on patients in our centre with recurrent NPC from February 2002 to February 2017. Patients were identified from the database of the otolaryngology oncology division at our institution. Of these, 28 patients met all our inclusion and exclusion criteria. We calculated sensitivity and specificity as well as average number of nodes per patient. RESULTS: In our study, we calculated the false negative and false positive rates of preoperative MRI neck by levels. Overall sensitivity of MRI picking up disease by level was 76% and specificity was 86%. CONCLUSION: Based on our study, we will be missing a total of 10 (7.1%) diseased neck levels in eight (28.5%) patients. MRI alone, therefore, does not provide enough information to allow safe selective preservation of neck levels in surgical salvage of neck recurrences in NPC.

RESUMO

Objective: To analyze the efficacy of different targets low-frequency repetitive transcranial magnetic stimulation (rTMS) for the treatment of tremor Parkinson's disease(PD). Method: A total of 82 patients with primary PD who were admitted to the Department of Neurology, Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 1, 2020 to March 31, 2021 were prospectively collected. According to the clinical characteristics of major movement disorders, 82 patients with tremor type (TD) were selected to enroll.The patients were randomly divided into 3 groups at a 1∶1∶1 ratio according to the randomized coding sequence of the trial: the primary motor cortex (M1) group with 26 cases, the cerebellum group with 26 cases and the dual-site (M1, cerebellum) group with 30 cases. All patients were treated with 1 Hz low-frequency stimulation of the corresponding target once a day for 5 days a week for 2 weeks, a total of 10 times; The dosage remained unchanged during the treatment for all groups. Before and after 2 weeks' treatment, the patients were assessed with the Unified PD Rating Scale (UPDRS) and PD Quality of Life Questionnaire-39 (PDQ-39) without medication. Cortical excitability, namely transcranial magnetic stimulation motor evoked potential (TMS-MEP), [including resting motor threshold (rMT) and active motor threshold (aMT) examinations], timed up and go (TUG) and electromyographic tremor were conducted. Result: There were 82 patients, 39 males and 43 females, with an average age of (67±8) years. Before the treatment, there was no statistically significant difference in the evaluation indicators among the three groups (all P>0.05). After the treatment, the differences of the UPDRS-Ⅲ score [(38.9±2.5) vs (29.2±3.6) ], UPDRS tremor score [(23.7±2.1) vs (14.6±3.1) ], TUG time [(44.8±3.1) s vs (33.7±4.1) s], tremor amplitude [(480±126) µV vs (276±94) µV], PDQ-39 score [(51±13) vs (45±13) ], rMT [(36±17)% vs (43±13)%], and aMT [(26±16)% vs (31±12)%] were statistically significant (all P<0.01) from those before the treatment. There was no statistical difference in the above factors between the M1 group and cerebellum group (all P>0.05). There was no statistically significant difference in tremor peak frequency among the three groups before and after the treatment (all P>0.05). Conclusions: Dual-site low-frequency rTMS can improve PD tremor, while M1 or cerebellar low-frequency rTMS does not significantly improve PD tremor. Its mechanism may be to improve PD tremor symptoms by regulating cortical excitability.

RESUMO

Objective: To explore a simple and feasible method for the isolation and purification of hepatocytes, hepatic stellate cells (HSC), and lymphocytes from mice. Methods: The cell suspension was obtained from male C57bl/6 mice by hepatic perfusion through the portal vein digestion method and then isolated and purified by discontinuous Percoll gradient centrifugation. Trypan blue exclusion was used to determine cell viability. Glycogen staining, cytokeratin 18, and transmission electron microscopy were used to identify hepatic cells. Immunofluorescence was used to detect α-smooth muscle actin combined with desmin in HSCs. Flow cytometry was used to analyze lymphocyte subsets in the liver. Results: After isolation and purification, about 2.7×10(7) hepatocytes, 5.7×10(5) HSCS, and 4.6×106 hepatic mononuclear cells were obtained from the liver of mice with a body weight of about 22g. The cell survival rate in each group was > 95%. Hepatocytes were apparent in glycogen deposited purple-red granules and cytokeratin 18. Electron microscopy showed that there were abundant organelles in hepatocytes and tight junctions between cells. HSC had expressed α-smooth muscle actin and desmin. Flow cytometry showed hepatic mononuclear cells, including lymphocyte subsets such as CD4, CD8, NKs, and NKTs. Conclusion: The hepatic perfusion through the portal vein digestion method can isolate multiple primary cells from the liver of mice at once and has the features of simplicity and efficiency.

RESUMO

Objectives: To evaluate the clinical efficacy of the stratification medical treatment based on the motor complications risk estimation in improving the quality of life, motor symptoms and delaying the motor complications in Parkinson's patients. Methods: Outpatients and inpatients from Xinhua Hospital, Shanghai Jiao Tong University, were recruited between November 2019 and June 2020. The participants were all clinically diagnosed with PD and treated with anti-PD medications, but had no history of motor complications, with the 8-item Parkinson's disease questionnaire summary index (PDQ-8 SI)>18.59. At baseline, the demographic characteristics, PD medical history, levodopa dosage (LD) and levodopa equivalent dosage (LED) were collected, and the evaluation of PDQ-8, Unified Parkinson's disease rating scale (UPDRS)-Ⅱ and Ⅲ, Hoehn and Yahr (H&Y) grade, Hamilton anxiety scale-14 (HAMA-14), Hamilton depression scale-24 (HAMD-24), mini-mental state examination (MMSE), Pittsburgh sleep quality index (PSQI), and Epworth sleepiness scale (ESS) tools was accomplished in all participants. Meanwhile, a Parkinson's disease risk estimation scale for motor complications was used to assess patients' risk of motor complications, and thus the medication was stratified in PD patients accordingly. During the 6-month and 12-month follow-ups, the evaluation of the above-mentioned parameters was repeated in all participants. At the 3-month and 9-month follow-ups, the information of anti-PD medications, the occurrence of motor complications (motor fluctuations and dyskinesia) and adverse drug reactions were recorded, and PDQ-8 was also evaluated. Results: Two hundred and fifty-one patients completed the 1-year follow-up, with 135 males and 116 females. At baseline, the median age of the patients was 66 (60, 71) years and the median PDQ-8 SI was 31.2 (21.9, 40.6). Additionally, 15.9% (40/251) of the patients were at high risk of motor fluctuation, and 7.2% (18/251) were at high risk of dyskinesia. There were significant differences in the age of onset, disease duration, PD treatment duration, the scores of UPDRS-Ⅱ and Ⅲ, H&Y Grade, and PDQ-8 SI among PD patients of different risk groups (all P<0.05). In the 12th month, the median of PDQ-8 SI, Δ PDQ-8 SI and Δ UPDRS-Ⅲ was 12.5 (9.4, 18.8), -15.6 (-21.9, -9.4) and -9(-16, -4), respectively, which was statistically different from that of baseline (all P<0.05). The change of UPDRS-Ⅱ scores in the group with high risk of motor fluctuation was statistically different from that in the groups with low and moderate risk (P<0.05). The changes of PSQI score, LD and LED in the group with high risk of dyskinesia was statistically different from those in the groups with low and moderate risk (all P<0.05). During the follow-up, the incidence of motor fluctuation and dyskinesia was 9.56% (24/251) and 5.97% (15/251), respectively. Conclusion: The stratification medical treatment might have a positive intervention effect on promoting a better quality of life, improving motor symptoms and delaying motor complications in PD patients.

RESUMO

Objective: To investigate the clinical efficacy and safety analysis of bronchial thermoplasty (BT) in the treatment of severe asthma and asthma-chronic obstructive pulmonary disease overlap. Methods: The clinical data of 49 patients with asthma-COPD overlap who received BT in the University of Chinese Academy of Sciences Shenzhen Hospital from January 2016 to December 2018 and 50 patients with severe asthma who received BT in the same period were retrospectively analyzed. Patients were divided into overlap group and asthma group, and the baseline data of two groups were recorded. The pulmonary function before and after treatment (including forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), FEV1 as a percentage of predicted value (FEV1% pred)), hormone consumption, asthma control test (ACT) score, asthma quality of life questionnaire (AQLQ) score, asthma control questionnaire (ACQ) score, the overlap group before and after treatment COPD assessment test (CAT) score, modified British Medical Research Council (mMRC) score and postoperative respiratory adverse events in the next 3 weeks were comparatively analyzed. Results: The general baseline characteristics of the two groups are compared. The patients in the overlap group were older than those in the asthma group, and the course of disease and smoking history were longer than those in the asthma group. The inhaled hormone dosage in asthma group was greater than those in the overlap group ((64±11) years vs (48±11) years; 10.00 (10.00, 25.00) years vs 9.00 (1.75, 20.00) years; 20.00(2.00, 40.00) years vs 0 (0, 10.00) years; 320 (320, 640) µg/d vs 960 (320, 960) µg/d) (all P<0.05). The predicted values of lung function indexes FVC, FEV1, FEV1% pred in the overlap group before treatment were all lower than those in the asthma group (1.98 (1.43, 2.43) L vs 2.54 (2.02, 3.15) L; 0.92 (0.61, 1.26) L vs 1.69(1.17, 2.16) L; (50±16) L vs (65±14) L) (all P<0.05). There were no significant differences in ACT, ACQ, and AQLQ scores between the two groups before treatment (all P>0.05). Within 3 months after treatment, except for no significant improvement in FEV1% predicted value and inhaled hormone dosage in the overlap group (all P>0.05), other indexes in both groups were improved compared with those before treatment (all P<0.05). After 1 year of treatment, all indexes of the two groups were significantly improved than those before treatment, and all indexes of the asthma group were better than those of the overlap group (all P<0.05). In terms of respiratory adverse events occurring within 3 weeks after the operation, the incidence of cough and bloody sputum in the overlap group was higher than that in the asthma group, while the incidence of sputum and short-term wheezing was lower than that in the asthma group (all P<0.05). There were no statistically significant differences in the incidence of chest tightness, chest pain, segmental atelectasis and pneumonia between the two groups (all P>0.05), and the postoperative adverse reactions could be effectively controlled in a short period of time. Conclusion: BT treatment could not only improve the lung function, clinical symptoms and quality of life of asthmatic patients, but was also effective for asthma-COPD overlap patients. However, BT treatment had more benefits for asthmatic patients without serious adverse events occurred.

RESUMO

Objective: To evaluate the long-term effect and safety of chrono-chemotherapy combined with intensity modulated radiotherapy (IMRT) in locally advanced nasopharyngeal carcinoma (NPC). Methods: 160 patients with locally advanced NPC were randomly divided into a chrono group and conventional group according to random number table. In the first stage, all patients underwent two cycles of induced chemotherapy, consisting of docetaxel, cisplatin and 5-Fu every 21 days. Notably, patients received chrono-moduated chemotherapy according to circadian rhythm in the chrono group, and conventional chemotherapy in the conventional group. Then, 21 days after the completion of first stage, three cycles of concurrent cisplatin chemotherapy every 21 days were given to all patients during IMRT. The median follow-up after the completion of radiotherapy was 31 months. Long-term side effects and the survival of patients were observed. Results: Patients in the chrono group had significantly lower rates of hearing loss (22.72%), dysphagia (0) and neck fibrosis (4.54%) compared with those in the conventional group (39.13%、8.69%, 15.94%, respectively, all P<0.05). Meanwhile, the 1- year overall survival rates (97.0% vs 92.8%), 3-year overall survival rates (80.3% vs 81.2%), 1-year progression free survival rates (95.5% vs 87.0%), 3-year progression free survival rates (71.2% vs 73.9%), 1-year locoregional relapse-free survival rates (97.0% vs 95.7%), 1-year locoregional relapse-free survival rates (92.4% vs 92.8%), 1-year distant metastasis-free survival rates (97.0% vs 98.6%) and 3-year distant metastasis-free survival rates (90.9% vs 91.3%) between the chrono group and the conventional group were not statistically significant (all P>0.05). Conclusions: Compared with conventional chemotherapy, chrono-chemotherapy combined with IMRT didn't affect long-term survival, but reducing the incidence of adverse events in patients with locally advanced NPC.

RESUMO

Objective: To investigate the feasibility of cationic antimicrobial peptide cathelicidin-PY(PY) therapy through a mouse model of acute liver failure. Methods: The ability of different concentrations of antimicrobial peptide PY to neutralize endotoxin / lipopolysaccharide (LPS) in vitro was detected by Limulus Amebocyte Lysate (LAL) assay. Cell counting kit-8 (CCK-8) was used to detect the toxic effect of different concentrations of antimicrobial peptide PY on mouse monocyte macrophages (RAW264.7). An in vitro hemolysis experiment was used to evaluate the activity of antimicrobial peptide PY on healthy human erythrocytes. D-galactosamine combined with LPS- induced mouse model of acute liver failure was constructed. The antimicrobial peptide PY effect on survival rate of mouse model was observed. HE staining was used to observe the pathological changes of liver tissue. Immunohistochemistry and Western blotting were used to detect the expression of apoptosis-associated protein caspase-3. Intra-group comparisons were performed using t-test and analysis of variance. χ (2) test was used for the comparison of rates. Results: An in vitro experiment showed that the endotoxin neutralization rate was higher at very low dose (0.01 µmol/L), and exceeded 70% at medium-dose (10-40 µmol/L), and the difference between groups with different concentration was statistically significant (F = 569.22, P < 0.05). Medium-dose antimicrobial peptide PY had strong endotoxin neutralizing effect, low cytotoxicity and hemolytic activity. Moreover, in vivo experiments showed that the degree of liver injury and survival rate of mouse model was significantly improved with the medium-dose of antimicrobial peptide PY. Immunohistochemistry results showed that the expression of caspase-3 in the liver tissue was significantly depleted in the medium-dose group than that of the liver failure group, and the results were consistent with protein immunoblotting testing. Conclusion: Antimicrobial peptide PY possesses a strong ability to neutralize endotoxin and few toxic side effects. A specific dose of antimicrobial peptide PY can attenuate hepatocyte apoptosis and significantly improve the survival rate of animal model, and thus provides a new idea for the liver failure treatment.

RESUMO

Objective: To explore the clinical characteristics and establish a corresponding prognostic scoring model in patients with early-stage clinical features of hepatitis B-induced acute-on-chronic liver failure (HBV-ACLF). Methods: Clinical characteristics of 725 cases with hepatitis B-related acute-on-chronic hepatic dysfunction (HBV-ACHD) were retrospectively analyzed using Chinese group on the study of severe hepatitis B (COSSH). The independent risk factors associated with 90-day prognosis to establish a prognostic scoring model was analyzed by multivariate Cox regression, and was validated by 500 internal and 390 external HBV-ACHD patients. Results: Among 725 cases with HBV-ACHD, 76.8% were male, 96.8% had cirrhosis base,66.5% had complications of ascites, 4.1% had coagulation failure in respect to organ failure, and 9.2% had 90-day mortality rate. Multivariate Cox regression analysis showed that TBil, WBC and ALP were the best predictors of 90-day mortality rate in HBV-ACHD patients. The established scoring model was COSS-HACHADs = 0.75 × ln(WBC) + 0.57 × ln(TBil)-0.94 × ln(ALP) +10. The area under the receiver operating characteristic curve (AUROC) of subjects was significantly higher than MELD, MELD-Na, CTP and CLIF-C ADs(P < 0.05). An analysis of 500 and 390 cases of internal random selection group and external group had similar verified results. Conclusion: HBV-ACHD patients are a group of people with decompensated cirrhosis combined with small number of organ failure, and the 90-day mortality rate is 9.2%. COSSH-ACHDs have a higher predictive effect on HBV-ACHD patients' 90-day prognosis, and thus provide evidence-based medicine for early clinical diagnosis and treatment.

RESUMO

Objective: To investigate the effect of different drugs on tracheal stenosis caused by transforming growth factor-ß/rapamycin target protein (TGF-ß/mTOR) signaling pathway. Methods: Thirty rabbits were randomly divided into normal control group, normal saline group, penicillin group, budesonide group and erythromycin group. The normal control group was not treated,and tracheal stenosis models were established in the other groups. From the 1st to 10th day after modeling, each group was respectively administered with normal saline (0.75 ml/kg, 2 times/d), intramuscular injection of penicillin (40 000 U/kg, 2 times/d), gastric administration of erythromycin (12.5 mg/kg, 2 times/d), inhalation of budesonide (0.05 mg/kg, 2 times/d). Rabbits were sacrificed on the 11th day after surgery, and tracheal specimens were collected to measure the degree of tracheal stenosis. Relative mRNA expression level of interleukin-6 (IL-6), transforming growth factor-ß (TGF-ß), Type Ⅰ collagen (COL-1), Type Ⅲ collagen (COL-3), and Sirtuin 1 (SIRT-1) were detected by Real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR); protein expression of mTOR, phosphorylated protein kinase B (p-AKT), vascular endothelial growth factor (VEGF),SIRT-1 were detected by immunohistochemical analysis; protein expression of nuclear factor κB (NF-κB),phosphorylated nuclear factor κB (p-NF-κB),protein kinase B (AKT),p-AKT,mTOR were detected by Western blotting. Results: The degree of stenosis of normal control group was (14.02±2.86)%, saline group was (64.14±3.21)%, penicillin group was (49.11±2.96)%, budesonide group was (39.52±2.09)%, erythromycin group was (32.60±4.27)%. The differences between any two groups were statistically significant (all P<0.05). Except between erythromycin group and normal control group, the differences in relative expression of IL-6 mRNA between any two groups (1.00±0.00, 9.02±1.50, 4.25±0.87, 2.53±0.17, 1.31±0.56) was statistically significant (all P<0.05), and the differences in relative expression of TGF-ß mRNA among all groups (1.00±0.00, 6.92±0.84, 3.83±0.44, 2.13±0.25, 1.40±0.15) were statistically significant (all P<0.05). The relative expression of SIRT-1 mRNA among all the groups (1.000±0.000, 0.209±0.042, 0.375±0.034, 0.555±0.028, 0.667±0.032) was statistically significant different (all P<0.05); except between erythromycin group and budesonide group,the protein levels of SIRT-1 among all other groups (16.93±2.28, 4.77±1.45, 7.70±0.61, 10.76±1.04, 11.03±1.10) were statistically significant different (all P<0.05). The protein levels of mTOR (9.28±4.56, 58.18±8.12, 44.75±5.56, 32.82±5.99, 24.73±3.56) and p-AKT (16.57±4.86, 61.79±6.66, 42.98±5.99, 32.79±5.34, 24.00±4.40) determined through immunohistochemistry of all groups were statistically significant different (all P<0.05). The protein levels of NF-κB, p-NF-κB, AKT, p-AKT and mTOR determined through Western blotting had the same trend as that of determined through immunohistochemistry. The protein expression of NF-κB,AKT and mTOR in saline group were significantly higher than other groups; those protein expression of erythromycin group was lower than budesonide group and penicillin group. Except between the erythromycin group and the normal control group, the protein expression of mTOR in other groups was statistically significant different (all P<0.05). Conclusion: Penicillin,erythromycin and budesonide can alleviate inflammation by increasing SIRT-1, alleviate tracheal scar hyperplasia induced by TGF-beta/mTOR pathway, and reduce the degree of tracheal stenosis in rabbits.

RESUMO

Objective: To explore the prognostic value of model for end-stage liver disease (MELD) combined with arterial blood lactate (Lac) in admitted patients with hepatitis B virus-associated acute- on-chronic liver failure (HBV-ACLF). Methods: Clinical data of 97 cases with hepatitis B virus-associated acute- on-chronic liver failure (HBV-ACLF) admitted to the First Affiliated Hospital of Suzhou University between March 2016 and March 2018 was retrospectively analyzed. Age, gender, complications, MELD score, lactic acid (Lac), total bilirubin (TBil), creatinine (Cr), serum albumin (Alb), high-sensitivity C-reactive protein (CRP), white blood cell count (WBC), platelet count (PLT), hematocrit (Hct), quantification of HBV DNA and HBsAg, and organ support treatment (artificial liver support system, renal replacement therapy and mechanical ventilation ) were documented after admission. The primary endpoint of treatment was death due to ineffective medical treatment during hospitalization, abandonment of medical treatment due to deterioration of the health condition, and switch to liver transplantation for patients with poor medical treatment. The risk factors for primary endpoint of treatment were analyzed by binary logistic regression. Hosmer-Lemeshow test was used to evaluate the goodness of fit for the scoring system, and the ROC to predict the prognosis of MELD-Lac. Results: Ninety-seven cases with HBV-ACLF were included, 56 cases had good prognosis, and 41 cases had bad prognosis (including two cases with poor medical treatment and liver transplantation). The overall improvement rate was 57.7%. MELD score and Lac value in treated group was significantly lower than non-treated group. Bivariable and multivariable logistic regression analysis showed that the MELD score [odds ratio (OR = 1.806)], and Lac score [odds ratio (OR = 1.820)] was the risk factor for hospitalization and mortality in patients with liver failure (P < 0.05). The area under the ROC curve (AUC) and the 95% confidence interval (95% CI) of prognostic patients with MELD-Lac were significantly better than Lac and MELD scores [0.923 (0.84 to 1.00) vs. 0.804 (0.067 to 0.942) and 0.864 (0.75). 0.977)], P < 0.05. When the MELD-Lac Youden index was set at 0.746, the optimal threshold was 18.36, and the sensitivity and specificity were 91.3% and 83.3%, respectively. Conclusion: MELD-Lac score has a high prognostic value in HBV-ACLF patients.

RESUMO

Objective: To investigate the methods of optometric refraction adopted for adolescents in spectacles stores in Anyang city of Henan Province and the professional performance of optometric refraction. Methods: Cross-sectional study. Maps and yellow pages were used to collect the information of 131 spectacles stores in Anyang city. A questionnaire was used to investigate spectacles stores that had optometry equipment and can provide refraction prescription and spectacles in this city. The questionnaire covered (1) the process of optometric refraction, including whether cycloplegic refraction was conducted for adolescents and children if it was their first-time optometry and the type of cycloplegics,and (2) the opticians' knowledge on optometric refraction for adolescents and children, such as necessity of cycloplegic refraction for adolescents and children and age cut-offs. According to whether they used a comprehensive refractometer, the optometry methods were divided into conventional optometry and medical optometry. Results: Of 131 spectacles stores in Anyang city, 127 were enrolled. A total of 127 questionnaires were distributed and returned with an effective rate of 100%. Conventional optometric refraction was performed in 53 stores (41.73%), and medical optometric refraction was performed in 74 stores (58.27%). Cycloplegic refraction was conducted in only 4 spectacles stores (3.15%) for adolescents and children upon their first-time optometry. The fogging method of refraction was adopted in 31 stores (24.41%), while optometric refraction was directly conducted in 92 stores (72.44%) without controlling accommodation. As for the use of cycloplegia at initial optometric refraction of children, cycloplegia was objected to in 4 stores,and thought to be no need in 28 stores including 6 stores in which the fogging method was used to replace cycloplegia. In 68 stores, cycloplegia was performed if wanted, or children could go to a hospital for it. In 12 stores, the use of cycloplegics was determined by children's vision and diopters. In 5 stores, children were suggested to go to a hospital for cycloplegic refraction. Cycloplegic refraction was required in only 4 stores. As to the age cut-offs of cycloplegic refraction, 6 years old, 12 years old, and 18 years old were considered as the boundary in 7 stores, 33 stores, and 9 stores, respectively.In 11 stores, age was only considered for amblyopia and hyperopia, and in 67 stores, it was not realized. Conclusions: Cycloplegic refraction was found to be conducted for adolescents and children in only 3% of the spectacles stores in Anyang city. Moreover, most of the spectacles store opticians did not support to use cycloplegia before optometric refraction for adolescents and children and lacked knowledge on the age cut-offs of cycloplegic refraction.Standardized training of cycloplegic refraction should be further strengthened.

RESUMO

GSK2878175 is a potent, pan-genotypic, non-nucleoside, nonstructural protein 5B palm polymerase inhibitor being developed for the treatment of chronic hepatitis C (CHC). A first-in-human, randomized, placebo-controlled, dose escalation study, evaluated the safety and pharmacokinetics of GSK2878175 administered as single and repeat oral doses (once daily for 14 days) to healthy volunteers. A separate proof-of-concept, placebo-controlled, repeat dose (once daily for 2 days) study evaluated the safety, pharmacokinetics and antiviral activity of GSK2878175 monotherapy in treatment-naïve, noncirrhotic, subjects with hepatitis C virus (HCV) genotype 1 [1a and 1b], 2, or 3. No deaths or SAEs were reported in either study, and treatment was well-tolerated. Across all the HCV genotypes, GSK2878175 monotherapy at doses of 10, 30 or 60 mg once daily for 2 days produced a statistically significant multilog reduction (P<.001) in plasma HCV RNA log10 IU/mL from Baseline to 24, 48 and 72 hours after the first dose of GSK2878175 compared to placebo. The reduction in HCV RNA was sustained for a prolonged period across all of the active treatment groups, consistent with the long apparent half-life of GSK2878175 that was observed (mean t1/2 range: 60-63 hours in the CHC subjects). In summary, GSK2878175, when administered to healthy subjects and subjects with CHC, did not reveal any safety concerns that would limit or preclude further clinical development. GSK2878175 monotherapy across a wide dose range produced substantial reduction in HCV RNA, irrespective of HCV genotype. The results from these studies support further evaluation of GSK2878175-based regimens.

RESUMO

A new technique for the realization of a stable Q-switched operation in a single-frequency fiber laser based on self-injecting polarization modulation is demonstrated, for the first time to the best of our knowledge. A piezoelectric fiber stretcher was utilized to introduce periodic stress-induced polarization changes. Then the modulation of polarization state transformed into Q switching by virtue of a designed distributed Bragg reflector (DBR) resonant cavity with polarizations loss anisotropy. Finally, a stable actively Q-switched single-frequency fiber laser at 1.5 µm with Gaussian-shape pulse output was achieved. We experimentally found that, the repetition frequency (several hundred kHz) coincided with the working frequency of the polarization modulation, and the pulse width (several hundred ns) reduced with the increasing of the modulating frequency, the modulating amplitude, as well as the pump power. This stable Q-switched single-frequency fiber laser is promising for applications in optical time-domain reflectometry, coherent Doppler wind radar, and optical coherent detection. More importantly, this novel Q-switched technology may be applicable to other DBR single-frequency fiber lasers.

RESUMO

Objective: To observe the clinical efficacy and safety of the LOP regimen (L-asparaginase, vincristine, dexamethasone) combined with intensity modulated radiation therapy(IMRT)in the treatment of early nasal NK/T cell lymphoma. Method: Clinical data of 65 patients with nasal NK/T cell lymphoma treated with LOP chemotherapy combined with IMRT at the Guizhou Province Tumor Hospital between March 2010 and January 2015 were retrospectively analyzed. Results: Among the 65 patients, 39 cases obtained complete remission (CR), 18 cases obtained partial remission(PR), 1 case obtained stable disease (SD), 7 cases had progressive disease(PD). The objective response rate (ORR) was 87.7%, the disease control rates (DCR) was 89.2%. The DCR was lower in the patients with B symptoms or over age of 60. Patients with super cavity obtained a worse progression-free survival(PFS). The 1-, 2-, 3-year PFS were 91.7%, 74.8% and 61.3%, the overall survival(OS) were 91.8%, 81.3% and 78.9%, respectively. Main adverse reactions were myelosuppression, gastrointestinal reaction, hepatic lesion, hypoproteinemia, percutaneous reaction and oral mucosa reaction. No severe pancreatitis, severe anaphylaxis and toxic related death were observed. Conclusion: The LOP regimen combined with IMRT treatment for nasal NK/T cell lymphoma may have a good therapeutic effect, low toxicity, and good tolerance.

RESUMO

Objective: To investigate the expression and significance of autophagy in rabbit model of tracheal stenosis. Methods: A total of 18 rabbits were equally divided into 3 groups (blank control group, saline group, erythromycin group) in accordance with the random number table. After rabbit model of tracheal stenosis was established, no treatment was done with blank control group. Saline group was atomized with saline (0.54 mg/kg, 2 times/day), and erythromycin group was fed on erythromycin (7.5 mg/kg, 2 times/day) for 7 days before and 10 days after the operation. On the eleventh day, rabbits were executed, and their trachea were collected. The proportion of collagen fiber area of tracheal lamina propria (LP) and epithelium (EP) was assessed by Masson staining. The mRNA of autophagy associated gene-3 (ATG3) and autophagy associated gene-5 (ATG5) of tracheal mucosa were assessed by Real-Time Polymerase Chain Reaction (RT-PCR). The protein of microtubule-associated protein 1 light chain ß(3) (LC3B), ATG3 and ATG5 were assessed by Western blot. Results: The proportion of collagen fiber area of tracheal LP and EP of blank control group was (6.79±0.67)%, saline group was (40.55±5.40)%, erythromycin group was (27.48±0.43)%. The differences between any two groups was all statistically significant (all P<0.01). The relative value of ATG3 mRNA and ATG5 mRNA in saline group were significantly lower than blank control group (all P<0.01). Those value in erythromycin group were significantly higher than the saline group (all P<0.01). The protein levels of LC3B-Ⅱ/Ⅰ, ATG3 and ATG5 in saline group were significantly lower than blank control group (all P<0.01). After low dose of erythromycin intervention, all the protein levels were significantly higher than the saline group (all P<0.01). Conclusions: The expression of autophagy is decreased in rabbit model of trachea stenosis. Low dose of erythromycin could increase the expression of autophagy and at the same time alleviate the degree of fibrosis of the tracheal mucosa. Autophagy may alleviate tracheal fibrosis through up-regulating its expression level and play a protective role.

RESUMO

Objective: To investigate the effect of low dose erythromycin on the proliferation of granulation tissue after tracheal injury. Methods: Forty-two rabbits were randomly divided into 7 groups (n=6 each), group A (saline control group), group B (penicillin group), group C (low dose erythromycin group), group D (low dose erythromycin and penicillin group), group E (budesonide group), group F (low dose erythromycin and budesonide group), group G (low dose erythromycin, penicillin and budesonide group). All rabbits received tracheotomy, and the tracheal mucosa was scraped with a nylon brush 20 times for tracheal stenosis model. Rabbits were treated with corresponding drugs from a week before operation to 9 days after operation. The serum concentrations of transforming growth factor - beta 1 (TGF-ß(1)), vascular endothelial growth factor (VEGF), interleukin (IL) -6, IL-8 were determined and the tracheal specimens were harvested for measuring degree of stenosis on the 10th day after operation. Results: Serum concentrations of TGF-ß(1) in group A, B, C, D, E, F and G were (17.6±1.3), (18.2±3.1), (13.0±1.1), (14.0±1.0), (21.0±6.1), (13.6± 3.5), (8.2±1.3) ng/L; VEGF were (88.1±4.1), (85.8±4.3), (58.1±6.3), (56.5±2.4), (87.8±2.8), (57.0±3.7), (34.3±6.7) ng/L; IL-6 were (67.8±4.0), (66.1±3.5), (54.1±4.8), (52.1±3.2), (64.6±4.9), (49.4±4.2), (35.9±3.7) ng/L; IL-8 were (112.8±5.2), (116.6±4.1), (88.0±6.2), (85.5±3.5), (114.4±4.6), (82.6±3.8), (55.9±6.0) ng/L, respectively. The serum concentrations of TGF-ß(1), VEGF, IL-6 and IL-8 in group C, D, F and G were significantly lower than those in group A, B and E (all P<0.05). Compared with the other groups, the serum concentrations in group G were the lowest (all P<0.05). All 42 rabbits had tracheal stenosis with different degrees of proliferation of granulation tissue. The degree of tracheal stenosis in Group A, B, C, D, E, F and G were (53.3±4.4)%, (48.2±5.0)%, (24.3±4.4)%, (29.5±3.2)%, (47.8±6.5)%, (27.9±3.1)%, (15.6±2.0)%, respectively. The degree of tracheal stenosis in group C, D, F and G was significantly lower than that in group A, B and E, which had statistical differences (all P<0.05). Compared with the other groups, the degree of tracheal stenosis in group G was the lowest (all P<0.05). Conclusions: Low dose of erythromycin can effectively inhibit the proliferation of granulation tissue after tracheal injury in rabbits. And it has better effectiveness when combined with other antibiotics and hormone.

RESUMO

Liver failure refers to a series of clinical syndromes manifesting as coagulation disorders, jaundice, hepatic encephalopathy, ascites, and other decompensated abnormalities due to serious hepatic dysfunction or decompensation in terms of synthesis, detoxification, excretion, and biological transformation caused by a variety of factors. In recent years, with the development of the research on immunological pathogenesis of liver failure, the "three-hit" theory clarifies the pathogenesis of liver failure. Major therapeutic strategies for liver failure are to prevent hepatocyte necrosis, promote hepatocyte regeneration, create a good internal environment for hepatocyte regeneration, and actively prevent and treat complications. An understanding of the immune status of liver failure patients and early application of glucocorticoids at right timing may help to improve prognosis and reduce adverse reactions. Establishment of a quantitative or functional balance between different cell subsets and new thoughts on some key cytokines may provide new directions and targets for immune regulation of liver failure.

RESUMO

Objective: To investigate the present situation of diagnosis and treatment for primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG) and awareness of the relevant progress among Chinese ophthalmologists. Methods: This study was a cross-sectional, non-randomized sampling survey. Participants were ophthalmologists who attended the 11st Chinese Glaucoma Society Congress during November 11 to 12, 2016. They were invited to fill out a questionnaire. The questionnaire included participants' basic information and their knowledge about glaucoma diagnosis and treatment. The data collected through questionnaire were analyzed with SAS9.4. Results: A total of 450 questionnaires were distributed and 372 valid questionnaires were retrieved, with a response rate of 82. 7%(372/450). ISGEO classification system was adopted by 58.9% (219/372) of the participants as the diagnostic criteria for PACG. Of the respondents, 48.1% (179/372) of the participants believed that "anterior chamber angle closure mechanism-based PACG classification system" was more instructive for treatment, the percentage was higher than ISGEO classification system (42.2%, 157/372). Most (72.3%, 269/372) of the participants knew the 3-minute dark room prone test, but only 27.7%(103/372) of them applied it in clinical practice. A total of 83.4%(310/372) of the participants believed that low cerebrospinal fluid pressure is a risk factor for POAG. In all, 71.8% (267/372) of the participants reported that their institutes had applied compound trabeculectomy with adjustable suture, with 76.9%(286/372) of the participants agreeing that the adjustable suture reduced the rate of complications after trabeculectomy. Conclusions: Currently, both ISGEO classification system and anterior chamber angle closure mechanism-based PACG classification system were adopted in the diagnosis and treatment of glaucoma. Low cerebrospinal fluid pressure as new risk factors for POAG has been widely acknowledged and given attentions by Chinese ophthalmologists. The 3-minute darkroom prone test and compound trabeculectomy with adjustable suture still need to be promoted. (Chin J Ophthalmol, 2017, 53: 115-120).
