Objective To investigate the relationship between Oxfordshire community stroke project (OCSP) classification and MRI classification in acute cerebral infarction. Methods A total of 282 patients with acute cerebral infarction were retrospectively evaluated with OCSP classification and imaging characteristics. Results According to OCSP classification, of all 282 patients with acute cerebral infarction, 32 (11.3%) experienced total anterior circulation infarction (TACI), 86 (30.5%) partial anterior circulation infarction (PACI), 111 (39.4%) lacunar infarction (LACI), and 53 (18.8%) posterior circulation infarction (POCI). The consistency was found in 201 cases (71.3%) between the OCSP classification and imaging classification, with the accuracy of 77% (27/35) for TACI, 79% (42/53) for PACI, 69% (95/137) for LACI and 65% (37/57) for POCI. Conclusion OCSP classification can predict the location and size of cerebral infarction with a high accuracy, and is well consistent with the MRI findings.
Objective To investigate the treatment method of senile patients with femoral intertrochanteric fractures and its cl inical outcomes. Methods From January 2005 to December 2007, 192 senile patients with femoral intertrochanteric fractures were treated, including 85 males and 107 females aged 65-92 years old (average 75 years old). The injury was causedby fall on walking in 106 cases, fall when riding a bicycle in 55 cases, and traffic accidents in 31 cases. According to Evans classification, there were 12 cases of type I A, 43 cases of type I B, 29 cases of type II, 24 cases of type III A, 23 cases of type III B, 26 cases of type IV, and 35 cases of type V. One hundred and fifty patients were associated with cardio-cerebrovascular diseases, 120 patients were compl icated with chronicle hypertension, 90 cases were associated with bronchitis, and 75 cases were compl icated with diabetes. The time from injury to hospital admission was 1 hour to 14 days. Among those patients, 108 were treated with conservative treatment, 68 received dynamic hip screw (DHS) fixation, and 16 underwent proximal femoral Gamma nail fixation. Results All the patients were followed up for 12-36 months (average 18 months). The fracture all reached bone union without occurrence of nonunion and delayed union. Patients could take care of themselves, and there were no occurrences of serious pains and dysfunctions. The therapeutic effect was satisfactory. The conservative treatment group: the average hospital stay length was 48 days; the average bone heal ing time was 14 weeks; 23 cases had different degrees of coxa adducta; Harris score system was adopted to evaluate hip joint function, 45 cases were graded as excellent, 31 as good, 10 as fair, and 22 as poor, and the excellent and good rate was 70.4%. DHS internal fixation group: the average operation time was 60 minutes; the average bleeding volume during operation was 200 mL, the average hospital stay length was 24 days; the average bone heal ing time after operation was 12 weeks; Harris score system was adopted to evaluate the injured hip joint function, 38 cases were graded as excellent, 21 as good, 8 as fair, and 1 as poor, and the excellent and good rate was 86.8%. Gamma nailfixation group: the average operation time was 70 minutes; the average bleeding volume during operation was 200 mL, the average hospital stay length was 14 days; the average bone heal ing time after operation was 12 weeks; Harris score system was adopted to evaluate the injured hip joint function, 11 cases were graded as excellent, 4 as good, 1 as fair, and the excellent and good rate was 93.8%. Conclusion For geriatric femoral intertrochanteric fractures, operative treatment should be performed, the preoperative preparation should be sufficient, and individual-oriented treatment method should be selected on the basis of physical conditions of patients and the types of fractures.
Objective The baseline, clinical characteristics, and risk factors were analyzed in the stroke registry program of the Xinjiang Production Constraction Corp’s Hospital aimed to aid the clinical management and stroke prevention. Method A single center prospective method based on Lausanne Stroke Registry was used in this study. Patients generally, past history, living conditions, onset to treatment time, the stroke scale were collected with 1 year follow up. The investigators of follow up were single blinded. Result Eight hundred and ten ischemic stroke patients were included, of which 478 (59.01%) were male, 332 (40.99%) were female. The average age of these patients was 66.50±10.66 years. One year loss rate of follow up was 4.64%. Seven hundred and sixty-nine patients were diagnosis as acute cerebral infarction, 41 patients were TIA. The median time from onset to treatment was 15 hours. Lacunar infarction was the most common type with 334 (43.43%) patients. The average score of the National Institutes of Heath Stroke Scale was 5.55±7.24. The incidence of carotid artery plaque was 82.2%. Conclution Xinjiang region has its own characteristics of stroke with a higher carotid artery plaque rate and thrombolytic therapy ratio. Good stroke registration system could standardize the clinical behavior and promote the continuous improvement of medical quality.
Objective To explore the clinical characteristics of patients who were infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) of different genotypes. Methods A retrospective study was conducted on 111 SARS-CoV-2 infected cases at home and abroad admitted to Chengdu Public Health Clinical Medical Center between January and September 2020. The basic information, gene sequencing results (Pangolin typing method), clinical typing, first laboratory examinations 24 hours after admission, and whether repositive after discharge were collected. According to Pangolin typing, patients were divided into five groups: A, B, B.X, B.1.X and B.1.1.X. The basic information (age, sex, and origin), laboratory test results (lymphocyte count, C-reactive protein, serum amyloid A, CD3+ T lymphocytes, CD4+ T lymphocytes, and CD8+ T lymphocytes), clinical classification and whether repositive were compared among different genotype infected patients. Results Among the 111 infected patients, 54 (48.6%) were males and 57 (51.4%) were females. Their ages ranged from 16 to 87 years, with a median age of 49 years. In terms of clinical classification, there were 10 asymptomatic cases (9.0%), 10 mild cases (9.0%), 64 ordinary cases (57.7%), 13 severe cases (11.7%), and 14 critical cases (12.6%). There were 75 domestic cases (67.6%) and 36 imported cases (32.4%). Eighty cases (72.1%) did not return to positive, and 31 cases (27.9%) returned to positive. There were 8 cases infected by type A virus, 18 cases infected by type B virus, 26 cases infected by type B.X virus, 5 cases infected by type B.1.X virus, and 54 cases infected by type B.1.1.X virus. Among patients infected by different genotype viruses, no statistically significant difference was found in sex, age, clinical type, laboratory examination, or whether repositive (P>0.05), but there was statistically significant difference in the distribution of domestic and imported cases (P=0.016). Type B virus infected patients were mostly domestic cases, while type B.X virus infected patients were mostly imported cases. Conclusion The distribution of domestic and imported cases is different among SARS-CoV-2 of different genotypes.
