Objective To study the data of combined hepatocellular cholangiocarcinoma (CHCC) and to explore its clinical characteristics and prognostic factors. Methods Clinical data of 41 patients with radical resection of CHCC were retrospectively analyzed, and the prognostic factors were analyzed by univariate and multivariate analysis. Results In 36.6% cases of 41 patients with CHCC, the elevated levels of both AFP and CA19-9 were detected. And 78.0% cases got the elevated levels of CK7 and (or) CK19 and Glypcian-3 and (or) hepatocyte. Multiple analysis revealed lymph node involvement was independent prognostic factor for overall survival. Conclusions CHCC is a special type of primary liver cancer and shows some intermediated characteristics between hepatocellular carcinoma and cholangiocarcinoma. The long-term survival of the patients should be affected by the residual of metastasis lymph nodes, and the surgical treatment should be individualized at the present stage.
Carney complex (CNC) is a rare autosomal dominant syndrome, characterized by pigmented lesions of the skin and mucosa, cardiac, cutaneous and other myxomas and multiple endocrine tumors. The disease is caused by inactivating mutations or large deletions of the PRKAR1A gene located at 17q22–24 coding for the regulatory subunit type Ⅰ alpha of protein kinase A (PKA) gene. Most recently, components of the complex have been associated with defects of other PKA subunits, such as the catalytic subunits PRKACA (adrenal hyperplasia) and PRKACB (pigmented spots, myxomas, pituitary adenomas). We reviewed CNC’s clinical features, diagnosis, treatment and molecular etiology.
ObjectiveTo investigate the clinical manifestations of patients with cardiac myxoma and the factors affecting the occurrence of embolic events. Methods A retrospective study of 38 patients with cardiac myxoma diagnosed and surgically removed from January 2010 to December 2017 was performed. There were 11 males and 27 females at age of 32-75 (50.00±16.12) years. The patients were divided into a non-embolized group and an embolized group. The clinical manifestations of the patients were summarized and the factors leading to embolism were analyzed. RseultsOf the 26 patients in the non-embolized group, 22 patients (84.62%) had dyspnea, 14 patients (53.85%) had palpitations, 4 patients (15.38%) had angina pectoris, and 1 patient (3.85%) had heart failure. Of the 12 patients in the embolized group, 4 patients (33.33%) had dyspnea, 3 patients (25%) had palpitations, and 1 patient (8.33%) had angina pectoris. The mean diameter of the non-embolized group was 5.71±1.63 cm, and the maximum diameter of the tumor in the embolized group was 4.52±1.88 cm. There was no significant difference between the maximum diameter of the tumor in the embolized group and the maximum diameter of the non-embolized group (P>0.05). Atrial fibrillation occurred in 2 patients in the non-embolized group before operation. Atrial fibrillation occurred in 5 patients in the embolized group. Atrial fibrillation was more likely to occur in the embolized group (P<0.05). Conclusion Atrial fibrillation in the patients with cardiac myxoma is closely related to embolic events. The size of myxoma is not related to the occurrence of embolic events.
ObjectiveTo investigate the clinical characteristics and genetic phenotype of mitochondrial myopathy associated with lactic acidemia and stroke-like seizure syndrome (MELAS) in DNA A3243G mutation, and to improve the clinical understanding and diagnosis.MethodsThe clinical data and imaging characteristics of 4 patients with DNA A3243G mutation-related MELAS syndrome who were diagnosed and treated in the Department of Pediatric Neurology, Henan Provincial People's Hospital from June 2017 to June 2018 were retrospectively reviewed.ResultsOf the 4 patients, 3 were caused by convulsions, 1 was caused by dizziness, and the MELAS syndrome caused by mitochondrial DNA A3243G mutation was confirmed by genetic testing. The patients were treated with anti-epilepsy drugs. The patients were followed up for at least 1 year, and 2 of 4 patients were stable, 1 patient still had seizures, and 1 patient did not improved.ConclusionsThe clinical phenotypic heterogeneity of patients with DNA A3243G mutation-related MELAS syndrome is caused by the " heterogeneity” and " threshold effect” of DNA mutation. The mutation rate of DNA A3243G is as high as 80%. In the era of promoting precision medicine, genes examination can help early diagnosis and early treatment of MELAS syndrome as well as improve the quality of life of patients and improve the prognosis.
ObjectiveTo investigate the clinical features and influencing factors for new-onset atrial fibrillation (AF) early after coronary artery bypass grafting.MethodsThe clinical data of 339 patients undergoing coronary artery bypass grafting in our hospital from January 2012 to January 2019 were retrospectively analyzed. There were 267 males and 72 females with an average age of 37-83 (58.03±8.90) years. The clinical features and influencing factors for new-onset AF after surgery were investigated.ResultsThere were 234 patients of off-pump coronary artery bypass grafting (OPCABG), with 36 (15.4%) new-onset AF patients after operation, among whom 16.1% were males and 12.5% were females. There were 105 patients of on-pump coronary artery bypass grafting (CABG), with 39 (37.1%) new-onset AF patients, among whom 40.7% were males and 25.0% were females. The incidence was higher after the CABG surgery than that after the OPCABG surgery (37.1% vs. 15.4%, P<0.05). There was no statistical difference in the incidence rate between males and females (P>0.05). The incidence of new-onset AF after surgery was higher in ≥60 years patients for both operations (18.9% and 45.8%), which was significantly higher than that in <45 years patients (P<0.05). For both operations, the incidence of new-onset AF after surgery was high on the second day (24-48 h) after surgery, and most of the AF lasted for 1 day (P<0.05). The hypertension (OR=4.983, P=0.036), frequent premature atrial contraction or atrial tachycardia (OR=17.682, P=0.002), postoperative creatine kinase isoenzyme MB (CKMB) (OR=0.152, P=0.042), left anterior and posterior diameters (OR=17.614, P<0.001) and preoperative ejection fraction (OR=7.094, P=0.011) were influencing factors for new-onset AF after OPCABG. Diabetes (OR=11.631, P=0.020), other cardiac malformations (OR=29.023, P=0.002), frequent premature ventricular contraction or ventricular tachycardia (OR=0.047, P=0.001), and postoperative CKMB (OR=3.672, P=0.040) were influencing factors for new-onset AF after CABG.ConclusionThe incidence of new-onset AF after CABG is higher than that after OPCABG, and it increases with age increasing. There is no difference in the incidence between males and females. The influencing factors for the two operations are different.
ObjectiveTo compare the clinical features of bacterial liver abscess (BLA) with or without diabetes and provide reference for clinical diagnosis and treatment.MethodsThe clinical data of 312 patients with BLA admitted to Huaian First People’s Hospital of Nanjing Medical University from January 2016 to January 2020 were collected. The differences in the clinical symptoms and signs, results of laboratory, imaging, etiological tests, treatment methods, and outcomes of the patients between with and without diabetes were compared.ResultsA total of 312 patients with BLA were collected, 128 BLA patients with diabetes and 184 BLA patients without diabetes. ① There were no significant differences in gender and age between patients with and without diabetes, but the boby mass index of BLA patients with diabetes was higher than that of the patients without diabetes [(25.54±4.99) kg/m2 versus (23.75±3.92) kg/m2, t=3.546, P<0.001]. ② In terms of etiology, the main cause of BLA was the biliary tract infection [37.18% (116/312)]. The incidence of cryptogenic infections in the BLA patients with diabetes was significantly higher than that of the BLA patients without diabetes [39.06% versus 26.63%, χ2=5.386, P=0.020]. ③ In terms of clinical manifestations, the fever was the main symptom of BLA [97.76% (305/312)]. The incidences of abdominal pain and percussion pain in the liver area of BLA patients with diabetes were significantly lower than those in the BLA patients without diabetes [32.03% versus 51.63%, χ2=11.793, P=0.001; 15.63% versus 30.98%, χ2=9.572, P=0.002]. ④ In terms of laboratory tests, compared with the patients without diabetes, the albumin level was lower [(30.88±5.25) g/L versus (33.67±4.33) g/L, t=–5.139, P<0.001], the procalcitonin level and neutral cell ratio were higher [(44.22±39.56) μg/L versus (36.03±22.73) μg/L, t=2.312, P=0.021; (86.68±7.05)% versus (80.73±8.12)%, t=6.710, P<0.001] in the patients with diabetes. ⑤ In terms of imaging findings, the BLA was mainly single abscesses [77.56% (242/312)] and mainly in the right lobe [66.34% (207/312)]. ⑥ In terms of microbiological examination, the bacterial positive detection rate of all patients was 71.15% (222/312). The main pathogen was Klebsiella pneumoniae [71.62% (159/222)]. The Klebsiella pneumoniae infection rate in the BLA patients with diabetes was higher than that in the BLA patients without diabetes [79.30% versus 66.67%, χ2=4.161, P=0.041]. ⑦ The septic shock occurred in 20 (6.41%) patients with BLA. After treatment of all patients, 4 cases of BLA with diabetes and 2 cases of BLA without diabetes died. The patients who died all came from septic shock.ConclusionsClinical manifestations of BLA patients with diabetes are atypical and main infection is Klebsiella pneumoniae. When BLA combined with septic shock, individual treatment strategy should be chosen basing on actual situation of patient.
ObjectiveTo analyze the clinical features and prognosis of coronavirus disease 2019 (COVID-19) patients.MethodsA total of 379 confirmed COVID-19 patients admitted to Public Health Clinical Center of Chengdu from January 16 to November 30, 2020 were divided into two groups including an elderly group (42 patients, ≥60 years) and a non-elderly group (337 patients, <60 years) by age. The epidemiology, clinical features, laboratory tests, treatment and prognosis of the two groups were compared.ResultsAmong the 379 patients, 286 (75.5%) were males and 93 (24.5%) were females, aged from 2 months to 87 years, with an average age of 41.2 years. The average age of the elderly group was 69.5 years, and 61.9% of them were females. They were imported from Wuhan or local secondary patients (73.8%), mainly common or critical type (88.1%). While, the average age of the non-elderly group was 37.8 years, and males were more common (80.1%). There were mostly from foreign input (75.7%), mainly mild or ordinary type (95.0%). A total of 179 patients (47.2%) had one or more underlying diseases. Hypertension (15 patients, 35.7%) and diabetes (11 patients, 26.2%) were more common in the elderly group, while non-alcoholic steatohepatitis (132 patients, 39.2%) was more frequent in the non-elderly group. The most common clinical manifestations were fever (138 patients, 36.4%) and cough (129 patients, 34.0%). Fever, cough, dyspnea, and fatigue were more common in the elderly group than those in the non-elderly group (P<0.05). Compared with the non-elderly group, the elderly group had lower total lymphocyte count, CD4+ and CD8+ T-cell count, higher level of myocardial injury or inflammation markers (P<0.05). Abnormal echocardiography in 139 patients (36.7%) was mainly caused by decreased left ventricular diastolic function (22.7%) and heart valve regurgitation (14.0%), and the rate in the elderly group was significantly higher than that in the non-elderly group (85.7% vs. 30.6%, P<0.05). After treatment, 3 patients in the elderly group died, and the others were cured and discharged. The hospitalization duration of the elderly group was longer than that of the non-elderly group (22.1 d vs. 18.8 d, P=0.033).ConclusionsElderly COVID-19 patients are mainly imported from Wuhan or secondary to the local population, mainly common or critical type, often associated with basic diseases such as hypertension or diabetes. While, non-elderly COVID-19 patients are mainly imported from abroad, mainly mild or common type, often associated with non-alcoholic steatohepatitis. After treatment, most of the patients have a good prognosis.
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.
Objective To investigate the clinical characteristics and death risk factors of patients with community acquired pneumonia and sepsis. Methods Data of 350 patients with community-acquired pneumonia and sepsis admitted to the Intensive Care Unit of Third Xiangya Hospital of Central South University from January 2015 to October 2021 were retrospectively analyzed, and their basic characteristics, laboratory results and treatment were analyzed. Results The absolute value of white blood cell, neutrophil ratio, absolute value of neutrophil, inflammatory index, liver and kidney function, coagulation function, cardiac enzymology, lactic acid and sequential organ failure evaluation score of patients with community acquired pneumonia sepsis in the non-survival group were higher than those in the survival group. Logistic regression analysis showed that respiratory rate, heart rate, mean arterial pressure, blood oxygen saturation, C-reactive protein, D-dimer, lactic acid, creatinine and lymphocyte ratio may be independent risk factors for 28-day death in patients with community-acquired pneumonia and sepsis.The receiver operating characteristic curve shows that the combination of the above indicators to predict the risk of death of patients has the best sensitivity, specificity and maximum area under the curve, which is superior to the prediction value of individual variables. Conclusions Patients in the non-survivor group of community-acquired pneumonia sepsis had more severe inflammatory response and organ function impairment. Respiratory rate, heart rate, mean arterial pressure, blood oxygen saturation, C-reactive protein, D-dimer, lactic acid, creatinine, lymphocyte ratio and other indicators are independent risk factors for death of patients with community-acquired pneumonia and sepsis, which have better prognostic value when combined.
Objective To present the pooled quantitative evidence of clinical features and current treatments of programmed death 1 (PD-1) / programmed death-ligand 1 (PD-L1) inhibitor-associated vasculitis. Methods Medline, Embase, EBM, CNKI, WanFang Data and VIP databases were searched for all available studies reporting PD-1/PD-L1 inhibitor-associated vasculitis till March 23, 2022. We summarized and systematically reviewed the included articles, and analyzed the data results with descriptive statistical methods. Results A total of 38 articles were included, including 43 patients. The median age [median (minimum, maximum)] was 62 (31, 89) years, and most of patients were male (64.3%). Lung cancer was the most common tumor (47.6%). The median onset time of vasculitis [median (minimum, maximum)] was 12 (1, 120) weeks after medication. Small vasculitis (62.8%) and cutaneous vasculitis (26.7%) were the most common types. The Common Terminology Criteria for Adverse Events of vasculitis was predominantly 3-4 (83.7%). After diagnosed with vasculitis, PD-1/PD-L1 inhibitors were discontinued in 81.6% of patients, and glucocorticoid was administrated in 88.4% of patients. After treatment, 90.0% of patients had significant improvement during follow-up. However, when the discontinuation of PD-1/PD-L1 inhibitors, 55.6% of patients tumor progressions, and 35.0% of patients dead. Conclusions Special attention should be paid to the occurrence of vasculitis when using PD-1/PD-L1 inhibitors for malignant tumor therapies. Stopping PD-1/PD-L1 inhibitors and using glucocorticoid are the essential methods to treat vasculitis, but the above treatments may bring a high risk of tumor progression.
