RESUMO
BACKGROUND:Scoliosis mainly refers to sequence abnormalities in the coronal,sagittal,and axial positions of the spine,with a Cobb angle of≥10°.The patients may experience symptoms such as unequal shoulder height and back asymmetry.Severe cases may affect the patient's cardiopulmonary function,thereby affecting their daily life.Conservative treatment can control the progression of scoliosis and avoid later surgery.Scoliosis orthosis is currently a commonly used and effective treatment measure in conservative treatment. OBJECTIVE:To summarize and analyze the current research status,hotspots,and trends of scoliosis orthoses both domestically and internationally,providing reference for related research. METHODS:Using bibliometrics and visual analysis as tools,and using a comparison between China and foreign countries as a method,this paper analyzes the literature on scoliosis orthosis journals in the past decade.Based on bibliometrics,the current status of research on scoliosis orthoses is determined.Citespace software is used to analyze key words and identify the current hotspots and future trends in scoliosis orthosis research. RESULTS AND CONCLUSION:(1)At present,the number of literature on scoliosis orthoses is still on a fluctuating upward trend.China and the United States are the main countries for research,with a literature share of over 40%.However,the average citation rate of foreign language literature by Chinese scholars is relatively low.(2)The basic fields of domestic research are mainly surgery and pediatrics,while orthotics and clinical neurology are mainly studied abroad.Among them,there is also a certain number of documents in domestic Chinese medicine,indicating that China is also engaged in the combination of Chinese and Western treatment of scoliosis.The National Natural Science Foundation of China has the highest proportion in the aspect of Chinese and foreign literature,reflecting the importance of the fund attaches to the research of scoliosis orthosis.(3)The authors with the highest number of publications are Qiu Yong and Negrini Stefano,and the most published institutions are the Spinal Surgery Department of Gulou Hospital affiliated to Nanjing University Medical College and UDICE-French Research University.Domestic and foreign authors and institutions have certain communications about this,but not closely,which requires relevant institutions and scholars to further explore and study.(4)From the research hotspots and future trends,the main treatment type is adolescent idiopathic scoliosis,while the production method of the short-column side bending orthosis is three-dimensinoal printing,and the main treatment index is convex progression.The ultimate purpose of treatment is to improve the quality of life of the patients.
RESUMO
Objective:To analyze the epidemiological and clinical characteristics of hospitalized patients with dengue fever in Guangdong Province in 2019, so as to provide reference for clinical diagnosis and treatment of dengue fever.Methods:The general data, laboratory examination data, clinical manifestations and prognosis data of 480 inpatients with dengue fever admitted to Eight People′s Hospital Affiliated to Guangzhou Medical University between January 4 and October 31, 2019 were analyzed retrospectively. The clinical and onset characteristics of patients with dengue fever were described.Results:Among 480 dengue patients, 442(92.1%) were dengue fever, 38(7.9%) were severe dengue, and 136(28.3%) had underlying diseases. The peak age of onset was mainly in young adults aged 20 to 49 years old, accounting for 66.0%(317/480) in total. The seasonal peak was mainly in August to October. There were 399(83.1%) local cases and 61(12.7%) imported cases. The most common clinical manifestations were fever (98.1%, 471/480), chills (72.9%, 350/480), headache (58.5%, 281/480) and bone/joint/muscle pain (67.1%, 322/480), followed by digestive tract symptoms and respiratory tract symptoms. Among 446 serum samples, 358 (80.3%) were dengue virus (DENV)-1, 54 (12.1%) were DENV-2, 34 (7.6%) were DENV-3. The main laboratory tests of the patients were leucopenia (65.8%, 316/480), low hematocrit (30.2%, 145/480), thrombocytopenia (48.3%, 232/480), neutropenia (44.8%, 215/480), elevated alanine aminotransferase (ALT) (37.7%, 181/480) and aspartate aminotransferase (AST) (59.4%, 285/480). Treatment mainly adopted symptomatic support treatment and active prevention of complications. The length of stay was (5.8±3.1) days (range 1.0-38.0 days). A total of 461(96.0%) patients were cured or improved.Conclusions:In 2019, the majority of dengue fever patients in Guangdong Province are young adults aged 20 to 49 years old, and the proportion of severe patients is high, with DENV-1 infection as the main type. After symptomatic support treatment and active prevention of complications, most of the dengue fever patients have a good prognosis.
RESUMO
Objective:To investigate the clinical characteristics and CT imaging features of patients with different clinical types of coronavirus disease 2019 (COVID-19), so as to provide a reference for the treatment and evaluation of COVID-19.Methods:The clinical data of 278 patients with COVID-19 admitted to Guangzhou Eighth People's Hospital from January 20th to February 10th in 2020 were collected. The patients were divided into mild, ordinary, severe and critical types. The differences of clinical symptoms and signs, laboratory examination indexes and CT image features of lung in different clinical types were analyzed and compared, and the relationship between clinical and imaging features and clinical types of diseases were analyzed.Results:Among the 278 patients with COVID-19, 130 were male (46.8%) and 148 were female (53.2%), of whom 88.8% (247/278) were 20 to 69 years old. 238 (85.6%) patients combined one or more basic diseases. The source of cases was mainly imported cases ( n = 201, 72.3%), of whom 89 cases were imported from Wuhan, accounting for 44.3% of all imported cases. With the aggravation of the disease, the male composition ratio, age and the number of basic diseases of patients gradually increased, and the incidences of fever, dry cough, chilly or chills, and fatigue in severe and critical patients were significantly higher than those in the mild and ordinary ones. The white blood cell count (WBC), neutrophil counts (NEU) and proportions (NEU%) of the severe and critical patients were higher than those of the mild and ordinary patients [WBC (×10 9/L): 5.7±3.1, 6.5±2.4 vs. 5.4±1.7, 4.9±1.6; NEU (×10 9/L): 4.4±3.1, 4.9±2.5 vs. 2.8±1.2, 2.9±1.3; NEU%: 0.72±0.13, 0.73±0.14 vs. 0.51±0.12, 0.59±0.11; all P < 0.01], while the lymphocyte count (LYM) and ratio (LYM%), platelet count (PLT) were lower than those in the mild and ordinary patients [LYM (×10 9/L): 1.0±0.4, 1.2±0.8 vs. 2.1±0.9, 1.5±0.6; LYM%: 0.21±0.11, 0.20±0.12 vs. 0.40±0.11, 0.32±0.11; PLT (×10 9/L): 177.1±47.8, 157.7±51.6 vs. 215.3±59.7, 191.8±64.3; all P < 0.05]. The level of albumin (Alb) was the lowest in the critical patients and the level of total bilirubin (TBil) was the highest, which was statistically significant as compared with the mild, ordinary and severe patients [Alb (g/L): 33.0±5.8 vs. 42.8±4.4, 39.6±5.1, 34.4±4.2; TBil (μmol/L): 20.1±12.8 vs. 12.0±8.7, 10.9±6.3, 12.2±8.3; both P < 0.01]. Lactate dehydration (LDH) and cardiac troponin I (cTnI) in the severe and critical patients were significantly higher than those in the mild and ordinary patients [LDH (μmol·s -1·L -1): 5.6±2.2, 5.0±2.9 vs. 2.8±0.9, 3.3±1.2; cTnI (μg/L): 0.010 (0.006, 0.012), 0.010 (0.006, 0.012) vs. 0.005 (0.003, 0.006), 0.005 (0.001, 0.008); both P < 0.05]. C-reactive protein (CRP) level of severe patients were higher than that in the mild, ordinary and critical patients [mg/L: 43.3 (33.2, 72.1) vs. 22.1 (16.2, 25.7), 29.7 (19.8, 43.1), 25.8 (23.0, 36.7), P < 0.01]. The level of procalcitonin (PCT) in the severe and critical patients was higher than that in the mild and ordinary patients [μg/L: 0.17 (0.12, 0.26), 0.13 (0.09, 0.24) vs. 0.06 (0.05, 0.08), 0.05 (0.04, 0.09), P < 0.01]. The typical CT imaging features were as follows: the ordinary type mainly showed the single or multiple ground glass shadows on the chest image; the severe type mainly showed the multiple ground glass shadows, infiltration shadows or solid transformation shadows. Compared with the ordinary patients, the lesions increase, and the scope of the lesion expanded to show double lungs. Critical type was mainly manifested as diffuse consolidation of both lungs with multiple patchy density increase shadows, multiple leafy patchy density increase shadows were seen on each leaf, most of them were ground glass-like density, and some were shown separately lung consolidation. Conclusions:Men, advanced aged, and combining multiple underlying diseases are high-risk populations of COVID-19, and they should pay close attention to the risk of progressing to severe or critical type. CT imaging features could be used as an important supplement when diagnosing severe and critical COVID-19.

Objective:To analyze the clinical characteristics of patients with different types of coronavirus disease 2019 (COVID-19).Methods:A total of 272 eligible COVID-19 patients who were admitted to Guangzhou Eighth People′s Hospital, Guangzhou Medical University from January 22 to February 15, 2020 were retrospectively enrolled. General characteristics, the first laboratory examination and imaging data of these patients were collected. According to the clinical classification, there were 236 cases in non-severe group (mild+ common type) and 36 cases in severe group (severe+ critical type). Comparisons between groups were performed by t test, chi-square test or rank-sum test when appropriate. Results:There were 23 males and 13 females in the severe group, 103 males and 133 females in the non-severe group, and the difference was statistically significant ( χ2=5.149, P=0.023). The age of severe group was (60.5±11.2) years, which was higher than that of non-severe group (46.8±15.7) years. The difference was statistically significant ( t=6.43, P<0.01). The lymphocyte (LYM) count, platelet (PLT) count and arterial partial pressure of oxygen (PaO 2) in the severe group were 0.90(0.55, 1.10)×10 9/L, 170.00(143.50, 198.00)×10 9/L and 73.50(69.70, 83.00) mmHg(1 mmHg=0.133 kPa), respectively, which were all lower than those in the non-severe group (1.42(1.09, 1.95)×10 9/L, 187.00(148.00, 230.00)×10 9/L and 96.00(83.20, 108.00) mmHg, respectively). The differences were all statistically significant ( Z=5.59, 2.00 and 5.00, respectively, all P<0.05). The levels of creatine kinase (CK), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), C reaction protein (CRP) and procalcitonin (PCT) in the severe group were 123.00(79.00, 212.00) U/L, 32.10(27.00, 47.40) U/L, 305.50(216.00, 396.00) U/L, 37.02(23.92, 63.66) mg/L and 0.09(0.05, 0.19) μg/L, respectively, which were all higher than those in the non-severe group (68.00(48.00, 103.00) U/L, 20.10(16.70, 26.20) U/L, 179.00(150.00, 222.00) U/L, 26.55(18.11, 36.96) mg/L and 0.04(0.03, 0.06) μg/L respectively), and the differences were all statistically significant ( Z=3.89, 5.60, 5.12, 2.85 and 5.43, respectively, all P<0.01). No significant differences were observed in white blood cell count, creatine kinase isoenzyme and blood lactate between the two groups ( Z=1.53, 0.41 and 1.00, respectively, all P>0.05). Conclusion:Gender, age, LYM count, PLT count, PaO 2, CK, AST, LDH, CRP and PCT could be used to provide reference for clinical classification of COVID-19 patients.
RESUMO
Objective:To retrospective analyze the epidemiology, clinical characteristics, treatment and prognosis in patients with coronavirus disease 2019 (COVID-19).Methods:A total of 278 patients with COVID-19 admitted to Guangzhou Eighth People′s Hospital from January 20 to February 10, 2020 were selected. The general demographic data, epidemiological data, clinical symptoms, laboratory examinations, lung CT imaging, treatment and prognosis were analyzed.Results:There were 130 male patients (46.8%) and 148 females (53.2%) with age (48.1±17.0) years and 88.8% patients between 20-69 years. Two hundred and thirty-six (84.9%) patients had comorbidities. Two hundred and eleven cases (75.9%) were common type. The in-hospital mortality was 0.4% (1/278). The majority (201, 72.3%) were imported cases mainly from Wuhan (89, 44.3%). The most common clinical manifestations were fever (70.9%) and dry cough (61.5%). In some patients, hemoglobin (10.4%), platelets (12.6%) and albumin (55.4%) were lower than the normal range. Other biochemical tests according to liver and function were normal, while lactic dehydrogenase (LDH) was elevated in 61 patients (21.9%), creatine kinase increased in 26 patients (9.4%). Prolonged activated partial thromboplastin time (APTT) was seen in 52 patients (18.7%), D-dimer higher than normal in 140 patients (50.4%), while 117 patients (42.1%) had elevated high-sensitivity C-reactive protein. Typical CT manifestations included single or multiple ground glass shadows especially in lung periphery in early disease which infiltrated and enlarged during progressive stage. Diffuse consolidation with multiple patchy density in severe/critical cases and even "white lung" presented in a few patients. Two hundred and forty-two patients (87.1%) received one or more antiviral agents, 242 (87.1%) combined with antibacterials, 191 (68.7%) with oxygen therapy. There were 198 patients (71.2%) treated with traditional Chinese medicine.Conclusions:COVID-19 could attack patients in all ages with majority of common type and low mortality rate. Clinical manifestations involve multiple organs or systems. Progression of the disease results in critical status which should be paid much attention.
RESUMO
Objective To evaluate the application value of early lung ultrasound score(LUS)in the eval-uation of severity and prognosis of severe pneumonia and investigate its correlations with oxygenation index(OI), alveolar-arterial oxygen difference(A-aDO2),lymphocyte count(LYM),positive end-expiratory pressure(PEEP), acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score,and clinical pulmonary infection score (CPIS). Methods Thirty severe pneumonia patients admitted to intensive care unit(ICU)of Guangzhou Eighth People's Hospital from May 2015 to July 2017 were enrolled,including 14 cases with low PEEP and 16 cases with high PEEP. Among them,17 patients were diagnosed with non-viral pneumonia and 13 ones with viral pneumonia;15 of them survived,and 15 died. The clinical data and cores of all patients were recorded by one observer,including baseline date,OI,A-aDO2,LYM,PEEP,and APACHEⅡ and CPIS score. The other observer was specifically responsible for pulmonary ultrasonography and LUS. The correlation between LUS and OI,A-aDO2,LYM,PEEP, as well as APACHEⅡand CPIS scores was analyzed by bivariate correlation analysis. Receiver operator character-istic curves(ROC)were plotted,and the prediction value,sensitivity and specificity of high PEEP and mortality by LUS were calculated respectively. Results LUS had a negative correlation with OI(r =-0.755,P = 0.000) and LYM(r =-0.518,P = 0.03),and a good positive correlation with A-aDO2(r = 0.642,P = 0.000),PEEP (r = 0.583,P = 0.001),APACHEⅡ(r = 0.461,P = 0.010)and CPIS(r = 0.595,P = 0.001)was respectively found. LUS in the survival group was significantly lower than the death group(15.00 ± 5.90 vs. 22.27 ± 4.68,P<0.01),low PEEP group was obviously lower than high PEEP group(14.23 ± 5.40 vs. 22.00 ± 4.98,P < 0.01), and there was no significant difference between non-viral pneumonia group and viral pneumonia group(18.59 ± 6.49 vs. 18.69 ± 6.56,P > 0.05). The area under ROC cure(AUC)was calculated:the predictive value for high PEEP by LUS was 19,with the sensitivity of 77% and specificity of 92%,and the patients with LUS > 17 had a high mortality,with the sensitivity for predicting death of 87% and specificity of 67%. Conclusion Bedside lung ultrasound can easily evaluate the changes in pulmonary ventilation area ,and early LUS has important clinical application value in assessing the severity and prognosis of severe pneumonia patients.
RESUMO
Objective To explore the clinical effect of ulinastatin on capillary injury improvement of renal syndrome hemorrhagic fever and renal leakage. Methods Patients were divided into 2 groups according to the random number table. The experimental group(25 cases)was given with ulinastatin and the control group(25 cases) was given 5% sugar solution as a blank control. All patients were treated with nutritional support ,rehydration , prevention of bleeding and other symptoms. In addition,according to the number of days of fever in the experimental group,the patients were divided into two groups. The experimental group A(9 cases)had fever 1 ~ 4 days;the experimental group B(16 cases)had fever 5 ~ 7 days. All patients were measured in microalbuminuria ,serum creatinine,plasma albumin and other clinical indicators after 7 day treatment. Results Compared with the control group,microalbuminuria of the experimental group was significantly decreased;Creatinine recovery rate was faster than that in the control group;Plasma albumin had significantly increased;The number of symptomatic days of concurrent perfusion of other tissues had also significantly reduced. Compared with the experimental group B , microalbuminuria of the experimental group A was significantly decreased;Creatinine recovery rate was faster than that in the experimental group B;Plasma albumin had significantly increased;The number of symptomatic days of concurrent perfusion of other tissues was also significantly reduced. Conclusion Ulinastatin could effectively treat vascular injury and syndrome due to capillary leakage caused by epidemic hemorrhagic fever virus ,and the best effect occurs in early application in the fever.
