The result indicated that the sphenopalatine ganglion stimulation with acupuncture as the main treatment of AR showed the better total response rate compared to conventional drugs, theOR(95%CI) was 3.22(1.81 - 5.75); however the change of total symptom score had no statistical significant difference, the MD(95%CI) was 0.69 (-0.56 - 1.93), the change of IgE had no statistical significant difference,theSMD(95%CI) was -0.07 (-0.97 - 0.83).Conclusion The main treatment on AR by sphenopalatine ganglion stimulation with acupuncture may has better efficacy than western medicine. But due to the methodological biases existed in most studies, future high-quality RCTs were needed to be included into Meta-analysis to test today’s study conclusion.

Objective: To explore the effect of modified cold therapy instrument on postoperative pain and swelling of patients with tibiofibular fracture. Methods: Eighty patients with tibia and fibula fracture who underwent surgery in Changzhou Cancer Hospital from June 2016 to June 2017 were selected and divided into control group and experimental group according to random number table method, 40 cases in each group. Patients in the control group were treated with conventional ice care, and the experimental group was treated with a modified cold therapy device. The Numerical Rating Scale (NRS) scores, tension blisters and skin dermatoglyphics, swelling and complications were observed before and after treatment. Results: Before the intervention, the difference in pain score and swelling degree between the two groups was not statistically significant (P>0.05). After nursing intervention, the pain scores of the two groups decreased, but the score of the experimental group was 2.2 ± 0.3, which was significantly lower than that of the control group (3.6 ± 0.5) (t= 15.185, P < 0.05); the incidence of tension blisters, the incidence of dermatoglyph and moderate swelling in the experimental group were 10% (4/40), 77.5% (31/40), 10% (4/40), which were lower than 30% (12/40), higher than 50% (20/20), less than 27.5% (11/40) of the control group (χ²= 5.000, 6.545, 4.021, P<0.05); no complications such as deep vein thrombosis and compartment syndrome were found in both groups. Conclusion The improved cold therapy device cold compress is better than the conventional ice dressing treatment, and can reduce the swelling and pain degree of the patients with tibiofibular fracture, which is beneficial to the rehabilitation of the patient and is worthy of clinical application.

Objective To investigate the prevalence of tuberculosis among silicosis patients and silica exposure patients,and to analysis the risk factors of tuberculosis among these population.Methods A total of 1 227 silica exposure patients from Wenling,Zhejiang were enrolled in this field study.Basic demographic information was collected and chest X-ray was taken for each patient.Sputum was collected for Mycobacterium tuberculosis culture and strain identification. In univariate analysis,t test was performed for continuous variables andχ2 test for categorical variables.In multivariate analysis,the odds ratio (OR )was calculated along with a 95 % confidence interval (CI )by binary Logistic regression. Results A total of 1 204 silica exposure patients had full basic information and 99.8% were male patients with mean age of (59.4 ± 6.8 )years.The patients in phase 0 + to phase Ⅲ were 172 (14.3%),255 (21 .2%),160 (13.3%)and 617 (51 .2%),respectively.The tuberculosis prevalence rate was about 7.3% among these population.The risk factors for tuberculosis including phase Ⅱ silicosis (OR =2.96, 95 %CI :1 .05 -8.32,P =0.04)and phase Ⅲ silicosis (OR=3.88,95 %CI :1 .58-9.56,P <0.01),and contacting with tuberculosis patients (OR=4.14,95 %CI :1 .91 -8.98,P <0.01).Patients complicated with tuberculosis lacked specific symptoms,but fever and weight loss were more frequent.Conclusion Tuberculosis is highly prevalent in silicotic patients,especially in patients with phase Ⅱ/Ⅲ silicosis and in patients with tuberculosis contact history.

Objective:To investigate the clinical characteristics of central nervous system tuberculosis in adults and the possible factors affecting the mortality and disability of the patients.Methods:The clinical data of patients diagnosed as "tuberculous meningitis" "tuberculous meningoencephalitis" "tuberculous cerebrospinal meningitis" or "tuberculous brain ubscess" in Huashan Hospital, Fudan University and Jing′an Branch, Huashan Hospital, Fudan University in Shanghai from January 1, 2010 to December 31, 2017 were collected, and a retrospective cohort was established. The clinical characteristics were analyzed, Medical Research Council (MRC) grade system was used to assess the severity of meningitis, and the modified Rankin Scale was used to assess the impairment of self-care. Survival rate and disability rate of the cohort were analyzed. Binary logistic regression was used for multivariate analysis. Kaplan-Meier survival curve was used for survival analysis.Results:A total of 161 patients with central nervous system tuberculosis were enrolled. Among the 161 patients, 55 cases (34.2%) were confirmed, 72 cases (44.7%) were highly suspected and 34 cases (21.1%) were suspected diagnosis. There were 56 cases (34.8%) with MRC grade Ⅰ, 76 cases (47.2%) with MRC grade Ⅱ and 29 cases (18.0%) patients with MRC grade Ⅲ before treatment. Up to January 1, 2019, ten (6.2%) patients died, 32 (19.9%) patients lost to follow-up, 119 (73.9%) patients survived. The five-year survival rate was 92.83%. There were 72 patients with no impact on life, 34 patients with moderate impact and 13 patients with severe impact. The disability rate was 39.5% (47/119). Binary logistic regression analysis showed that increasing age (odds ratio ( OR)=1.06, 95%confidence interval ( CI) 1.00 to 1.13, P=0.032) and deterioration of MRC grade during anti-tuberculosis treatment ( OR=89.00, 95% CI4.46 to 1 779.00, P=0.003) were independent risk factors for death. When severe disability and death were used as adverse outcomes, logistic regression analysis showed increasing age ( OR=1.07, 95% CI 1.01 to 1.13, P=0.035) and deterioration of MRC grade during anti-tuberculosis treatment ( OR=77.17, 95% CI4.45 to 1 337.00, P=0.003) were still independent risk factors for adverse outcomes. Conclusions:The mortality of central nervous system tuberculosis in adults in this cohort is relatively low, but the disability rate is still high. Increasing age and deterioration of MRC grade during anti-tuberculosis treatment are independent risk factors for death and disability.

Objective This study aimed to investigate the clinical characteristics of cryptogenic stroke as the first manifestation of occult systemic malignancy (OSM) and to determine whether plasma D-dimer levels and lesions in multiple vascular regions could predict occult systemic malignancy in patients with cryptogenic stroke. Methods Data from 83 patients including 9 patients with OSM and 74 patients without OSM were extracted from the stroke database of Beijing Shijitan Hospital. Clinical variables were analyzed between cryptogenic stroke patients with OSM and without OSM. The relationshiop between plasma D-dimer levels or lesions in multiple vascular regions and OSM were analyzed by multiple logistic regression analysis. Results Compare to patients without OSM, patients with OSM was older (66.8± 7.5 vs.56.4±15.7,P=0.004)and had lower hemoglobin levels (127.9±19.8 vs.143.6±17.7,P=0.015),higher conut score [3(1,3) vs. 1(0,2), P=0.011], higher plasma D-dimer levels (77.7% vs. 13.5%, P<0.001) and more common lesions in multiple vascular regions(100% vs.23.0%, P<0.001).Multiple logistic regression analysis revealed that high plasma D-dimer levels are independent risk factors for OSM (OR=26.250,95%CI:3.041-226.604,P=0.003).Conclusions Patients with OSM are elderly people and have poorer nutritional status, higher plasma D-dimer levels and more common lesions in multiple vascular regions. High plasma D-dimer levels can be useful to predict OSM in patients with cryptogenic stroke at earlier stages.

Objective:To take a broad overview of the current allocation of diagnosis and treatment resources and management for patients with tuberculous meningitis (TBM) in 49 hospitals in China.Methods:A cross-sectional survey about TBM was carried out in 49 hospitals from 27 provinces across China, by means of electronic questionnaire.The electronic questionnaire was filled by doctors in charge of the departments where TBM patients were routinely admitted from September to December 2018. The availability of medical resources, diagnosis, evaluation, treatment and surveillance in these hospitals were analyzed from the questionnaire. The count data were expressed as percentage.Results:Among the 49 participating hospitals, 37(75.5%) hospitals had less than 50 admissions of suspected TBM per year. Less than 20 TBM patients were confirmed by etiological diagnosis per year in 42(85.7%) participating hospitals.The availability of conventional medical imaging including computed tomography (CT), magnetic resonance imaging (MRI), enhanced MRI, cerebral angiography and magnetic resonance angiography (MRA) were 100.00%(49/49), 95.92%(47/49), 91.84%(45/49), 61.22%(30/49) and 67.35%(33/49), respectively. The rate of access to classic etiological diagnostic methods including acid-fast bacilli smear, mycobacterial culture and T cell spot test of tuberculosis infection were 77.55%(38/49), 95.92%(47/49) and 83.67%(41/49), respectively. Rifampin (100.0%, 49/49), isoniazid (100.0%, 49/49), pyrazinamide (98.0%, 48/49) and ethambutol (95.9%, 47/49) were most commonly used in initial anti-tuberculosis treatment of non-severe patients with TBM. The course of anti-tuberculosis treatment was 18 months in 25(51.0%) hospitals, and 12 months in 17(34.7%) hospitals. Intrathecal glucocorticoid and isoniazid were used in 39(79.6%) hospitals. Dexamethasone was used as part of treatment in 24(49.0%) hospitals, and the duration of glucocorticoid was about two months in 28(57.1%) hospitals. As for hyponatremia, 32(65.3%) hospitals didn′t investigate the cause, and hypertonic saline (83.7%, 41/49) and oral rehydration salts (71.4%, 35/49) were considered as the most common treatment strategy. Lumbar puncture was most commonly used for intracranial pressure surveillance in 48(98.0%) hospitals.Conclusions:The TBM cases admitted to the investigation hospitals are characterized by scattered sources and few confirmed cases of etiology. There are obvious heterogeneities in the diagnosis and treatment of TBM and the management of complications.The standardized plan for diagnosis and treatment of TBM are needed to improve the management.
