ObjectiveTo study the epidemiologic characteristics of primary liver cancer (PLC). MethodsThe literatures about regional distribution and etiologic epidemiology of PLC were reviewed. Results PLC was mainly distributed on caostland in the south-east of China. The main cause of PLC was hepatitis B virus, aflatoxin and contamination of drinking water. Otherwise, PLS was also related with lack of some trace element, sex horemones, genealogy cause and so on.Conclusion The genesis of PLC was by multiple factors.
Objective To analyze the epidemiological features of clavicle fractures.Methods A total of 363 cases of clavicle fractures were treated from February 1993 to November 2002, their case history data were reviewed and evaluated by epidemiological method.Results Out of 363 cases, there were 269 males and 94 females, aged from new born to 96 years. The locations of fractures were on left side in 159 cases and on right side in 204 cases. Neonatal clavicle fracture occurred in the case of delivery (0.28%). The causes of disease for adult clavicle fractures were traffic injury (52.1%) and daily falling injury(31.1%). There were232 cases of simple fractures and 131 cases of comminuted fractures. The fracture positions included inner(6 cases), middle(328 cases) and outer parts(29 cases). Multiinjuries occurred in 78 cases, the rib fractures concomitant with clavicle fractures were the commonest(31 cases).Conclusion The clavicle fractures are the common injury. Of them, traffic injury and daily falling injury arethe most common. The rib fractures are always accompanied with clavicle fractures.The main position of fracture is on the middle part.
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 epidemiological characteristics, clinical manifestations, laboratory examination and imaging findings of patients with coronavirus disease 2019 (COVID-19) outside Hubei Province in 2019.MethodsFrom January 21, 2020 to February 18, 2020, 17 patients with COVID-19 diagnosed by SARS-CoV-2 nucleic acid test in Xianyang Central Hospital of Shaanxi Province and 23 patients in Liaocheng Infectious Disease Hospital of Shandong Province were collected. The information of epidemiology, age, time of onset, first symptom, white blood cell, lymphocyte count, procalcitonin (PCT), serum amyloid protein A (SAA), C-reactive protein (CRP) and chest CT were collected and analyzed.Results40.0% of the 40 patients had a clear history of contact with Wuhan or other areas of Hubei, 60.0% had no clear exposure history, 60.0% were aggregative diseases, 40.0% were imported patients; the average visit time was (4.9±3.5) d, 35% of the patients had underlying diseases; 75.0% of the patients had fever, 7.5% of the initial symptoms were cough, 5.0% pharyngitis, 2.5% headache, and 10.0% were asymptomatic. In the laboratory examination, 77.5% of the patients' white blood cells were normal, 45.0% of the patients' lymphocyte count could be decreased, 72.5% and 55.0% of the patients' SAA and CRP increased respectively, 92.5% of the patients' PCT was normal, 92.5% of the patients were positive for the first nucleic acid test, and 72.5% of the patients' chest CT showed multiple ground glass lesions in one or both lungs, and the positive coincidence rate between the initial nucleic acid test and the chest CT test was 92.5%. 90% of the patients in the group were common type, and all patients were treated with aerosol inhalation of α-interferon combined with lopinavir/ritonavir tablets, 62.5% were treated with antibiotics and 15.0% were treated with glucocorticoid. All patients were improved and 14 patients were cured and discharged from hospital.ConclusionsSARS-COV-2 is highly contagious, family aggregation infection and asymptomatic infection may be the main mode of transmission outside Hubei Province, mild and common types are common, there are no specific changes in laboratory examination, and the condition is stable after treatment.
【Abstract】 Objective To explore the features of Ki-ras mutations at codon 12 in Chinese patients of pancreatic cancer and to compare these features with those in Western countries. Methods Fifty-nine samples were collected during operations for pancreatic adenocarcinoma in our hospital from December 1989 to November 1997. The patients, age ranged from 30 to 73 years 〔(55.5±10.4) years〕,with 38 males and 21 female. TNM staging of the patients: stage Ⅰ(n=4); stage Ⅱ(n=8), stage Ⅲ(n=42),stage Ⅳ(n=5). PCR was used to amplify target gene and Dot blot hybridization for detecting Ki-ras mutations at codon 12 was performed in fifty-nine specimens of Chinese pancreatic cancer. The data of Ki-ras mutations at codon 12 from Western countries were gotten by Medline system. Results Ki-ras mutation at codon 12 was detected in 76.3% of the patients in this group. The frequency of double mutation of Ki-ras at codon 12 in this group (15.6%) was highest than that in western countries. Our results were compared with those reported in Western countries. The results suggested that there were the significant differences in the substitution of Ki-ras mutations at codon 12 and in the ratio of transition to transversion in pancreatic cancer among various countries. Conclusion Ki-ras mutations at codon 12 is frequent in Chinese pancreatic cancer, and a gene component to pancreatic cancer may be different among various countries. In addition, the effect of Ki-ras mutations at codon 12 on prognosis of patients with pancreatic cancer is different in various countries.
ObjectiveTo investigate the current situation of ketogenic diet treatment centers in China, including the target, quantity, indication diseases, staffing and regional distribution of ketogenic diet therapy centers.MethodsMembers from the China Association Against Epilepsy (CAAE) received an investigation on the development situation of ketogenic diet therapy in their own epilepsy centers through an online survey. ResultsAt present, there are 91 centers for ketogenic diet therapy in China, and among them, there are 74 centers (81.32%) only treat pediatric patients. 59 centers of them (64.83%) were established between 2010 and 2020; patients of 63 centers (69.23%) have been treated with ketogenic therapy for status epilepticus (SE), among which only 9 centers (14.29%) have 5 or more epileptic patients on averge per month. 35 centers (38.46%) are offering ketogenic diet treatment for indications other than epilepsy. The main diseases are autism spectrum disorder, encephalitis, febrile infection related epilepsy syndrome (FIRES), rare diseases and glycolipid metabolic diseases. All ketogenic diet treatment centers are equipped with high-quality professionals, mainly neurologists and pediatric physicians; There are significant differences in regional distribution, with centers in the eastern region accounting for more than half (53.85%). ConclusionsThe development of ketogenic diet therapy in China has achieved initial results, but there are still some problems such as small number of patients treated and uneven geographical distribution.
Objective To investigate the clinical manifestation and radiological features of unknownetiology ostearthritic disease in Shigeng village of Chongzhou city in Sichuan province so as to lay a basis for further study. Methods The data were analyzed retrospectively. The epidemiology investigation, physical examination, movement functional assessment, lab test and X-ray examination were performed on 116 villagers of 3 years and more than. Quantitative analysis on roentgenography was conducted. Results Sixty-four villagers had unknown ostearthritic disease，the prevalence was 55.2%；17 patients were limp, the prevalence of limp was 26.6%，onset age mainly focused under 40 years. Main manifestation of osteoarthritic disease was fixed pain of knee joint or hip joint, and bilateral pain was significantly more than single pain, but local fever and swelling were not obvious. Mild or moderate pain account for 73.5% of patients, and pain was aggravated after physical labor or movement and could be relieved after rest. Joint pain had no influence on joint movement function for long time, leading to a limp due to the joint functional disorders at late stage. Physical examination illustrated the flexion contracture of the hip and limitation of internal and external rotation. The Harris scores were 86.5±17.1(left hip) and 86.3±17.2. 46 (right hip), and the excellent or good result was achieved in 46 patients, fair and poor results in 18 patients. The average HSS scores were 88.4±9.3(left knee) and 88.2±11.0(right knee). The excellent or good result was achieved in 61 patients, fair and poor results in 3 patients. The X-ray films showed degenerative disorders of hip joint such as narrowing of the joint space (47.6%)，articular surface sclerosis and deformation (30.2%), shallow and increased density acetabulum, increased obliquity and insuffi cient coverage of the femoral head by the acetabulum, and increased femoral neck-shaft angles. Radiological features of knee joint were bony spur or bony bridge，osteoporosis，incomplete and thickening articular surface with sclerosis and deformation，degenerative disorders. Conclusion Main clinical manifestation of unknown osteoarthritic disease in Chongzhou city was fixed pain of bilateral knee joint or combined with hip joint pain at early stage，and functional limitation in hip joint at late stage. Main radiological feature was hip joint degeneration. To effectively control the osteoarthritic disease ofthis area, much more etiology researches should be done.
ObjectiveTo analyze the diagnosis status and epidemiological characteristics of anti-N-methyl-D-aspartate receptor encephalitis (anti-NMDAR encephalitis) in the Sichuan province of China. MethodsIn the retrospective survey study, data of cases suspected as autoimmune encephalitis in Sichuan province from January 2012 to February 2017 were collected from the third-party test center.The diagnosis status and epidemiological characteristics of anti-NMDAR encephalitis were analyzed. Results① A total of 1 714 cases had been suspected as autoimmune encephalitis with anti NMDA receptor antibodies tested.In hospitals of capital city, cerebrospinal fluid or serum of 1 511 cases were tested since 2012.In other cities, 203 cases were tested since 2014.Hospitals with anti NMDA receptor antibodies tested increased by year.The cases distributed in the department of neurology, psychology, pychiatric, ICU, pediatrics, geriatrics, otolaryngology, infection, the mergency department and pneumology.② Cases with anti NMDA receptor antibodies tested increased by year.A total of 155 cases were confirmed as anti-NMDAR encephalitis, with the average onset age of (27.9±12.0) years ranged from 9 years to 77 years, including 89 women and 66 male.The female average age were (26.5±11.31) years, while the male were(29.0±13.0) years.③ Among the 155 confirmed cases, 127 cases with detailed clinical data were analyzed further.Seizure and behavior disorder were the main symptoms at onset.Among the 127 cases, 107 cases were misdiagnosed at their first hospital visit, with the misdiagnose rate of 84.3%.18 cases were reported with tumors (17 female), mainly with teratoma(11/17). ConclusionIn Sichuan province, the doctors of hospitals in non-capital city should strengthen the identification of autoimmune encephalitis.Anti-NMDAR encephalitis could be misdiagnosed easily and non-neurological physicians should also take attention;
ObjectiveTo investigate the clinicopathologic and epidemiological characteristics of patients with gastric cancer at our hospital in the past six years． Methods A total of 958 patients with gastric cancer were selected from January 2004 to December 2009 and clinicopathologic characteristics such as basic data, pathological type, tumor location, and TNM stage were retrospectively analyzed. ResultsOf the 958 patients，697 cases (72.8%) were male and 261 cases (27.2%) were female, and the age ranged from 26 to 91 years old (mean 62.6 years old). The occurrence rate of gastric cancer was higher in the patients of 46-65 years old (49.4%, 473/958) than that in the patients of ≥66 years old (42.3%, 405/958) and ≤45 years old (8.3%, 80/958). Regarding pathologic type, the majority of advanced gastric cancers (70.1%) were Borrmann Ⅱ, the adenocarcinoma and signetring cell carcinoma accounted for 82.3% and 7.8%, respectively. The cancer of gastric cardia accounted for 53.0%. Stagestratified analysis revealed that the majority of gastric cancers (47.4%) were stage Ⅲ. Conclusion①A prevalence of gastric cancer is found in middle, elderly male patients. Poorly differentiated adenocarcinoma in cardia is prominent. ②Patients with high malignant ganstrie cancer are younger. ③The majority of patients who underwent the surgical treatments have advanced or metastatic tumor, therefore it is necessary to improve the early diagnosis of gastric cancer.
ObjectiveTo analyze the clinical characteristics and epidemiological characteristics of patients with coronavirus disease 2019 treated early in Jiangxi province.MethodsFour-night patients with coronavirus disease 2019 treated in this hospital from January 21st to 27th, 2020 were included in this study. The epidemiological and clinical data of patients after admission were collected, and laboratory tests such as blood routine, urine routine, stool routine, liver and kidney function, electrolytes, myocardial enzymes, erythrocyte sedimentation (ESR), C-reactive protein (CRP), calcitonin, coagulation, T cell subset and Chest CT were reviewed. The clinical results of common and severe/critically ill patients were compared.ResultsOf the 49 patients, 40 were common and 9 were severe/critical. Fourty-six patients had a clear history of contact with Wuhan or other areas of Hubei. The sex ratio was 2.06∶1, and the average age was 42.9 years. The symptoms were mainly fever (78.7%), cough (38.8%), and fatigue (18.4%). 28.6% (14 cases) of patients had hypertension and diabetes. Serum lymphocyte count and calcium concentration of the patients were decreased, but lactate dehydrogenase, ESR, CRP and serum amyloid A were increased in these patients. T lymphocyte subsets (CD3+, CD4+, CD8+) decreased significantly in these patients. Forty-seven patients (95.9%) had single or scattered patchy ground glass density shadows on the chest CT. Compared with common patients, the patients with severe/critical patients were older (P=0.023), hospitalized later (P=0.002), and had higher comorbidities (P=0.017). ESR (P=0.001）, CRP (P=0.010) and the serum amyloid A (P=0.040) increased significantly, while CD3+ (P<0.001), CD4+ (P=0.012), CD8+ (P=0.006) decreased significantly in severe/critical patients.ConclusionsThe patients with coronavirus disease 2019 in Jiangxi province are commonly imported from Wuhan. Severe/critical patients are older, hospitalized later, and have more medical complications and more severe systemic inflammatory reactions than common patients.
