Objective To explore the characteristics of diagnosis and treatment for the rectal cancer in the young patients （≤40 years）．Methods The domestic and abroad literatures about the research on the progress of rectal cancer in the young patients were reviewed, the clinical data of patients with rectal cancer were compared between the young patients and the other age patients, the characteristics of diagnosis and treatment for the rectal cancer in the young patients were summarized．Results The onsets of the young patients with rectal cancer were related to the diet，lifestyle, and genetic factors．Compared with the older patients, more later stage, higher percentage of poor differentiation, earlier lymph node metastasis were found in the young patients with rectal cancer．Rectal cancer of the young patients was often misdiagnosed and with a poor prognosis．Currently，surgery assisted with neoadjuvant therapy was generally acknowledged as a better method．Conclusions It has specificity in epidemiology, pathology, treatment, prognosis, and so on for rectal cancer in the young patients, but surgery needs further research．
ObjectiveTo explore the clinical features and prognosis of ischemic cerebral infarction in young population,and to provide a reference for clinical prevention of cerebral infarction in young population. MethodsA total of 547 patients with ischemic cerebral infarction diagnosed between January 2008 and June 2013 were included,and the difference in clinical data and outcomes between young and old patients were retrospectively compared. ResultsThe 547 patients included 233 young and 314 old patients,and there were more male patients in young group.As compared to the old group,the proportion of hypertension was significantly lower in young group (51.9%,64.3%;P=0.004);while smoking (51.9%,5.7%;P=0.000) and alcoholism (53.2%,28.3%;P=0.000) were significantly higher in young group.Moreover,there were more patients with vascular malformations in young group than that in old group (7.3%,3.2%;P=0.028).And there were also more patients in young group received thrombolytic therapy and antiplatelet therapy (98.3%,86.9;P=0.000),and the prognosis of young patients was significantly better than that of old patients. ConclusionThe prognosis of young patients with ischemic stroke prognosis is relatively good,and changing bad habits would be an effective measure to prevent and reduce the occurrence of ischemic cerebral infarction in young population.
Objective To evaluate the therapeutic outcome of artificial total hip arthroplasty (THA) with collum femoris preserving for hip joint desease in young and middle-aged patients. Methods From March 2002 to March 2005, 26 cases (31 hips) of hip joint disease were treated with artificial THA with collum femoris preserving, including 19 males (23 hips)and 7 females (8 hips) and aged 32-48 years with an average of 37 years. In 31 hips, 17 left hips and 14 right hips were involved. There were 9 cases of osteoarthritis of the hip joint caused by avascular necrosis of the femoral head (ANFH), 7 cases of ANFH, 3 cases of femoral head necrosis caused by dysplasia of acetabular, 1 case of osteoarthritis of the hip joint caused by ankylosing spondyl itis, and 2 cases of rheumatoid arthritis; the course of disease was 2-11 years (5.6 years on average). Two cases of femoral neck fracture (Garden IV), and 2 cases of non-union femoral neck fractures (1 for Garden III and 1 for Garden IV), the course of disease was 5 days, 24 months, and 26 months. The prime symptoms were pain, difficult walk and l imp. All patients were taken X-ray to exclude osteoporosis. Results The right distal femur prosthesis of a bilateral patient cracked owing to excessive amputation of collum femoris, and fracture healed after symptomatic treatment. All the incisions healed by first intention and no compl ications occurred. All patients were followed up for 4-7 years, with an average of 5.6 years. One case had poor hip function because he did not follow rehabil itation procedure, and the others achieved good outcome with normal gait. One case complained of persistent pain 6 months after operation, and was rel ieved by administration of some non-steroidal antiinflammatory drugs and anti-osteoporosis drugs 6 months later. The X-ray films after operation and at last follow up showed good location of prosthesis and no bone resorption. Harris score at last follow-up was 91.31 ± 0.77, and it was significantly higher than that before operation (50.88 ± 0.90), (P lt; 0.05). The excellent and good rate was 93.5% (excellent in 11 hips, good in 18 hips, and fair in 2 hips). Conclusion Artificial THA with collum femoris preserving can retain more bone, be easier for revision, and has an excellent outcome.
ObjectiveTo investigate the clinical characteristics and prognosis of cerebral hemorrhage in young and elderly patients, to provide evidences for individual clinical diagnosis and treatment, and lay a foundation for building a predictive model of prognosis in cerebral hemorrhage.MethodsPatients with spontaneous cerebral hemorrhage in the Third People’s Hospital of Chengdu were recruited prospectively and continuously from January 2014 to January 2019. They were divided into the youth group (≤50 years old) and the elderly group (>50 years old), and their risk factors, disease characteristics, etiology, and prognosis were analyzed.ResultsA total of 757 patients were recruited. There were 160 cases (21.1%) in the youth group, including 120 males and 40 females, aged from 17 to 50 years, with an average age of (42.06±7.62) years old; 597 cases (78.9%) in the elderly group, including 361 males and 236 females, aged from 51 to 96 years, with an average age of (69.34±10.56) years old. The incidences of hypertension (74.2% vs. 51.2%), diabetes (15.1% vs. 4.4%), coronary heart disease (12.1% vs. 1.3%), and the level of blood glucose at admission [7.1 (5.8, 8.4) vs. 6.3 (5.3, 8.1) mmol/L] in the elderly group were higher than those in the youth group (P<0.05), respectively. However, the proportions of males (60.5% vs. 75.0%), smoking (24.5% vs. 36.9%), and the diastolic blood pressure at admission [(92.37±18.50) vs. (100.95±25.25) mm Hg (1 mm Hg=0.133 kPa)] in the elderly group were lower than those in the youth group (P<0.05), respectively. There was no significant difference between the two groups in systolic blood pressure at admission, Glasgow Coma Score, National Institutes of Health Stroke Scale score, initial hematoma volume, hematoma enlargement, brain hernia, location of hemorrhage, midline shift, hydrocephalus, combined subarachnoid hemorrhage, or intraventricular extension (P>0.05). Hypertension was the most common etiology in the two groups. There was a significant difference in the etiology of cerebral hemorrhage between the two groups (P<0.05), the difference was mainly reflected in cerebral amyloid angiopathy, cavernous hemangioma, and arteriovenous malformation. The fatality rate during hospitalization (9.4% vs. 20.9%), 3 months after discharge (10.3% vs. 26.3%), and at 1 year follow-up (19.0% vs. 37.6%) in the youth group was lower than that in the elderly group (P<0.05), respectively. The disability rate 3 months after discharge and at 1 year follow-up in the youth group was lower than that in the elderly group (32.1% vs. 44.2%, 16.9% vs. 34.4%; P<0.05), respectively.ConclusionsThe education of healthy lifestyles should be strengthened to reduce the adverse effects of smoking in young patients. Young patients should choose antihypertensives that can control diastolic blood pressure better. There are more structural abnormalities in young patients, so routine vascular examination is reasonable. It is necessary to focus on whether the original underlying diseases are stable in elderly patients. Cerebral amyloid angiopathy is an important cause of cerebral hemorrhage in elderly patients, and is a risk factor of recurrence. Anticoagulation or antiplatelet therapy should be cautious.
Objective To study the application and the curative effect of compressed screw and sartorius bone flap in treating femoral neck fractures in youth or middle age. Methods From February 1996 to December 2004, 86 patients with femoral neck fracture were treated by open reduction compressed screw and sartorius bone flap, aging from 21 to 49 years. Fracture was caused by traffic accident in 35 cases, fall from height in 27 cases and fall in 24 cases. Accoding to Garden classification, 23 cases were type Ⅱ, 25 cases were type Ⅲ, and 15 cases were type Ⅳ. We analyzed fracture healing and evaluate function by observation of the postoperative X-ray films. Results Of the 86 patients, 62 were followed up 6 months to 7 years (2 years and 5 months on average). According to Weijie’s criterion for nonunion and necrosis offemoral head, nonunion occurred in 4 cases; the healing rate of fracture was 93.5%. In healed patients, necrosis of femoral head occurred in 7 cases (11.3%) after 3 years. The results of hip joint function evaluation were excellent in 44 cases, good in 8 cases, fair in 6 cases and poor in 4 cases; and the excellent and good rate was 83.9%. Conclusion Compressed screw and sartorius bone flap was simple and effective for femoral neck fractures in youth or middle age.
ObjectiveTo investigate the predictive value of volatile organic compounds (VOCs) on pulmonary nodules in people aged less than 50 years.MethodsThe 147 patients with pulmonary nodules and aged less than 50 years who were treated in the Department of Thoracic Surgery of Sichuan Cancer Hospital from August 1, 2019 to January 15, 2020 were divided into a lung cancer group and a lung benign disease group. The lung cancer group included 36 males and 68 females, with the age of 27-49 (43.54±5.73) years. The benign lung disease group included 23 males and 20 females, with the age of 22-49 (42.49±6.83) years. Clinical data and exhaled breath samples were collected prospectively from the two groups. Exhaled breath VOCs were analyzed by gas chromatography mass spectrometry. Binary logistic regression analysis was used to select variables and establish a prediction model. The sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve of the prediction model were calculated.ResultsThere were statistically significant differences in sex (P=0.034), smoking history (P=0.047), cyclopentane (P=0.002), 3-methyl pentane (P=0.043) and ethylbenzene (P=0.009) between the two groups. The sensitivity, specificity and area under the ROC curve of the prediction model with gender, cyclopentane, 3-methyl pentane, ethylbenzene and N,N-dimethylformamide as variables were 80.8%, 60.5% and 0.781, respectively.ConclusionThe combination of VOCs and clinical characteristics has a certain predictive value for the benign and malignant pulmonary nodules in people aged less than 50 years.
