RESUMO
Objective:To explore the relationship between the abnormal adipose tissue around the primary tumor of colon cancer and the prognosis.Methods:From January 2015 to December 2017, 448 patients with colon cancer in Peking University Cancer Hospital were retrospectively and consecutively collected. The scores were assigned to the severity, horizontal and vertical ranges of peritumoral adipose tissue (PAT) abnormalities, and the cumulative scores were calculated to establish the PAT grades from 1 to 3. We defined a score of 0 or 1 as PAT grade 1, a score of 2 as PAT grade 2, a score of 3 as PAT grade 3. The patients were followed up, and the overall survival (OS) and metastasis-free survival (MFS) were recorded. The Kaplan-Meier curve, log-rank test and Cox regression analysis were used to evaluate its impact on prognosis, and the hazard ratio (HR) and 95% confidence interval (CI) were calculated.Results:Among the 448 patients, patients with PAT grade 1, 2, and 3 accounted for 70.1% (314/448), 18.1% (81/448), and 11.8% (53/448), respectively. The Kaplan-Meier survival curve showed that patients with PAT grade 1 had the best OS, patients with grade 3 had the worst OS, and patients with grade 2 were in between, and the difference was statistically significant (χ 2=27.38, P<0.001). There were statistically significant differences between the grades in pairs ( P<0.05). There was no significant difference in MFS between different PAT grades (χ 2=2.85, P=0.240). The results of Cox regression analysis showed that PAT grade was an independent factor affecting the OS. Compared with PAT grade 1, the risk of death in patients with PAT grade 2 and 3 was significantly increased (HR 2.563, 95%CI 1.181-5.561; HR 2.269, 95%CI 1.005-5.121; P=0.034). PAT grade was not an independent factor of MFS ( P=0.253). Conclusion:The PAT grade established based on the degree and scope of abnormal PAT in colon cancer is an independent factor for poor prognosis of colon cancer.
RESUMO
Objective:To investigate the value of CT findings in predicting thetransformation of clinical types of COVID-19.Methods:From January 24 to February 6, 2020, the clinical and chest CT data of patients with common COVID-19 were analyzed retrospectively. A total of 64 patients were enrolled, including 32 males and 32 females, aged 18-76 (45±15) years. Based on the fact whether patients’ conditions had deteriorated into severe type, all the cases were divided into common type group (51 cases) and deteriorated type group (13 cases). Differences of CT findings in the two groups of patients were analyzed, and visual semi-quantitative scores were introduced to evaluate the pneumonia.Results:Compared with the common type group, the deteriorated type group was more likely to involve the left upper lobe, the right middle lobe and the lung far away from the pleura. The differences between the two groups were statistically significant (χ2= 5.897, P=0.027; χ2=8.549, P=0.005; χ2=10.169, P=0.002). The median of the involved lobes were 2 (1,5) in the common type group and 5 (4,5) in the deteriorated type group. The difference between the two groups was statistically significant (Z =-3.303, P=0.001). Taking the involved lobes ( n=4) as the threshold, the sensitivity and specificity of the diagnosis of the common type to the deteriorated type patients were the highest, 76.9% and 74.5% respectively, and the area under the ROC curve was 0.787. Pneumonia score of the deteriorated group was 10 (4,16), higher than that of the common group [4 (1,13)], and the difference was statistically significant ( Z=-4.040, P<0.001). Pneumonia score 8 as the threshold, the sensitivity and specificity of the general severe group were the highest, 69.2% and 86.3% respectively, and the area under ROC curve was 0.863. Conclusions:CT imaging has a profound value in the early prediction of deterioration in clinical type of COVID-19. It can help evaluate the severity of pneumonia in early stage. Range of lesions might be an important indicator for prognosis of common type COVID-19.

RESUMO
The infructescence of Platycarya strobilacea is the dry infructescence of P. strobilacea, which is a traditional medicinal plant in China. It has functions of clearing up heat and detoxification, dispelling wind and relieving pain, activating blood circulation and removing stasis, clearing orifices and expelling pus. It is commonly used by people to treat various complications caused by acute and chronic rhinitis, sinusitis and acute upper respiratory tract infection, and is a kind of Chinese medicine with excellent development space and utilization value and has broad market prospects. There are many chemical constituents in the infructescence of P. strobilacea, including volatile oils, Phenols, flavonoids, terpenoids, carbohydrates and other compounds. Among them, volatile oils are the most abundant, but lack of correlated activity studies. Phenolic compounds, flavonoids and terpenoids are the main pharmacogenetics constituents. However, few of these compounds have been isolated and identified. Modern pharmacological studies have shown that the infructescence of P. strobilacea has many pharmacological activities, such as anti-tumor, anti-virus, anti-inflammatory and bacteriostasis, anti-aging, growth promotion, hypotension and sedation, but the existing studies mainly focus on anti-virus, anti-inflammatory and bacteriostasis, anti-tumor effects, and other activities have not been further explored. In the future, the chemical constituents and pharmacological activities of the infructescence of P. strobilacea should be studied in depth, and its mechanism should be further clarified so that it can be more fully and reasonably applied. By consulting domestic and foreign literature in recent years in CNKI, VIP database, Wanfang date, PubMed and other databases. The chemical constituents, pharmacological effects and clinical application of the infructescence of P. strobilacea were summarized and expounded its research progress in order to provide theoretical reference for further research and further development and application of the Infructescence of P. strobilacea.
RESUMO
Objective To investigate the feasibility,safety and efficacy of endovascular recanalization of the symptomatic occlusion of large intracranial artery in anterior circulation.Methods From October 2015 to December 2017,13 patients with symptomatic non-acute occlusion of large intracranial artery in anterior circulation were enrolled into this study and underwent endovascular recanalization.The initial procedural results,including the rate of successful recanalization and perioprocedural complications,and angiographic and clinical follow-up results were collected.The functional outcome was evaluated at discharge and 90 days.Results Recanalization was successful in 11 out of 13 patients.Perioperative complications occurred in 8 cases,including distal embolization in 7 cases (3 with symptom and 4 without),in which intracerebral hemorrhage associated with embolectomy was found in 1 case;and distal embolization concomitant with artery dissection in 1 case.At discharge,the symptoms of 10 out of 11 patients with successful recanalization were improved and 1 was unchanged;one of 2 patients with recanalization failure was aggravated and 1 was unchanged.After the procedure,1 patient with successful recanalization,but complicated with intracerebral hemorrhage associated with embolectomy was lost at follow-up,thus angiographic follow-up was available in the remaining 10 patients.Of the 10 patients,1 patient developed in-stent restenosis at 12 months and 9 patients had no hemodynamic stenosis/reocclusion.The clinical follow-up was available in 12 patients.No recurrence of TIA or stroke was found in 9 cases with successful recanalization except for 1 case who developed in-stent stenosis and suffered from TIA.At the follow-up of 90 days,l0 patients with successful recanalization showed good function (mRS∶0-2),2 patients with recanalization failure were deteriorated.Conclusions In strictly selected patients with symptomatic non-acute occlusion of large intracranial artery in anterior circulation,endovascular recanalization was feasible and safe,which may improve patients' symptoms in a short term and reduce the recurrence rate of stroke,but its definite efficacy needs to be confirmed by studies with larger sample and longer follow-up.
RESUMO
Objectives: To compare the clinical features and long-term outcomes of patients with apical hypertrophic cardiomyopathy (ApHCM) and patients with asymmetric septal hypertrophic cardiomyopathy (ASHCM). Methods: Data from 600 patients (300 with ApHCM and 300 with ASHCM) identified in a consecutive single-center cohort between 1996 and 2014 were retrospectively analyzed. The two groups were 1:1 matched by age of diagnosis, gender and the presence of outflow tract obstruction. Clinical features, cardiovascular mortalities, incidence of sudden cardiac death and cardiovascular morbidity (including unexplained syncope, atrial fibrillation, nonsustained ventricular tachycardia, progressive heart failure, embolic stroke or transient ischemic attack and myocardial infarction) were compared between the two groups. Results: Forty-two patients (14.0%) had a maximum LV wall thickness of ≥30 mm in the ASHCM group compared to only 11 patients (3.7%) in the ApHCM group (P<0.01). 156 patients in ApHCM group (52.0%)and 168 patients in ASHCM group(56.0%)underwent cardiovascular NMR examination, the incidence of late gadolinium enhancement was significantly lower in ApHCM group than in ASHCM group(26.9% vs 76.2%,P<0.01). The mean follow-up durations for ApHCM and ASHCM were (7.5 ± 4.0) years and (6.6 ± 5.4) years, respectively. The incidence of cardiovascular death (1.0% vs 5.7%), sudden cardiac death (0.33% vs 3.3%) and major adverse cardiovascular event (18.3% vs 40.3%) were significantly lower in the ApHCM group than in the ASHCM group (all P<0.01). Unexplained syncope, nonsustained ventricular tachycardia, and progressive heart failure were less common in ApHCM group than in ASHCM group (all P<0.05). Multivariate COX regression analysis showed that late gadolinium enhancement positivity (HR=4.62, 95% CI: 2.28- 68.0, P=0.02) and unexplained syncope (HR=8.56, 95% CI: 2.1-16.6, P<0.01) were independent predictors of cardiovascular mortality. Unexplained syncope was independent predictor for sudden cardiac death (HR=4.40, 95% CI: 1.5-15.2, P=0.02). Conclusions: After eliminating the interference of age at diagnosis, gender and outflow tract obstruction, patients with ApHCM represent a more benign prognosis with a lower incidence of cardiovascular mortality and morbidity than patients with ASHCM.

Objective To evaluate the diagnostic value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)for the differential diagnosis of the adenoid cystic carcinoma and pleomorphic adenoma of the head and neck.Methods Thirty-one pa-tients with histopathologically proved adenoid cystic carcinoma and pleomorphic adenoma were examined with DCE-MRI,in which 10 cases were benign and 21 cases were malignant.The data of the conventional 3.0T DCE-MRI were improved by the 3D fast spoiled gradient-echo sequence (FSPGR)method.Z-test was performed on the quantitative parameters for benign and malignant le-sions,including volume transfer constant (Ktrans ),rate constant (Kep )and extravascular extracellular space fraction (Ve ).The re-ceiver operating characteristic (ROC)curves were plotted to investigate the diagnosis.Results The mean Ktranss of the adenoid cystic carcinoma group and pleomorphic adenoma group were (0.266 ± 0.103 )min-1 and (0.1 55 ± 0.080)min-1 respectively,and the difference between them were statistically significant (Z =-2.699,P 0.05).The areas under the ROC curves of the Ktrans and kep were 0.813 and 0.763 respectively.Choosing the optimal diagnostic cut-off points corresponding to the maximum Youden indexes 0.173 min-1 and 0.818 min-1 ,the sensitivities of Ktrans and kep for identifying the adenoid cystic carcinoma and pleomorphic adenoma were 90.9% and 81.8%,and the specificities were 77.8% and 66.7%.Ktrans was of the highest sensitivity and specificity for the identification of the adenoid cystic carcinoma and pleomorphic adenoma.Conclu-sion The dynamic contrast-enhanced parameter Ktrans plays a certain role in the differential diagnosis of the adenoid cystic carcinoma and pleomorphic adenoma of the head and neck.
RESUMO
Objective To evaluate the safety and therapeutic effect of covered expandable metallic stent placement combined with interventional chemotherapy in treating malignant esophago-tracheal fistulae. Methods A total of 60 patients with esophago-tracheal fistula were enrolled in this study. The patients were randomly divided into control group (n=28) and study group (n=32). Patients of the control group were treated with covered stent implantation only, while patients of the study group were treated with combination use of covered stent implantation and interventional chemotherapy. All the patients were followed up regularly, the short-term and long-term results were determined, and the effect rate, median survival time and complications were statistically analyzed. Results Among the 60 patients, successful obstruction of the fistula was obtained in 58 with a success rate of 96.7%. The median survival time of the 58 patients was 5.8 months. The median survival time of the control group and the study group was 3.6 months and 8.7 months respectively, the difference between the two groups was statistically significant (P<0.05). The one-month, 3-month and 6-month effect rates were 78.1%, 68.8% and 62.5% respectively. The incidence of esophageal stent re-stenosis in the study group was much lower than that in the control group. Conclusion The combination use of covered stent implantation and interventional chemotherapy can effectively improve the median survival time of patients with malignant esophago-tracheal fistula, and reduce the occurrence of stent-related complications. Therefore, covered expandable metallic stent placement combined with interventional chemotherapy is an effective and safe treatment for malignant esophago-tracheal fistulae.
RESUMO
Objective To detect the volume changes of cerebral gray and white matter in patients with maintaining hemodialysis using voxel-based morphometry(VBM) and to correlate these changes with cognitive function. Methods Forty-two patients with maintaining hemodialysis and 41 age and sex matched normal subjects were recruited in this study. MMSE was obtained to evaluate their neuropsychiatric conditions. Whole brain high-resolution T1WI was performed on 3.0 T MR scanner in both patients and normal controls. The data were analyzed by VBM based on SPM8, using analysis of functional neuroimages (AFNI) software package with the Monte Carlo simulation method(AlphaSim method) for multiple cluster level comparisons correction. Independent sample t test analysis was used to compare the volume of gray and white matter between the patients and normal controls. In addition, Stepwise multiple linear regression analysis was performed to explore the correlation between the voxel value of cerebral volume changes area and dialysis duration and clinical laboratory examination, and Spearman correlation analysis was used for the correlation between the left insula voxel values and neuropsychological test scores. Results Compared with normal controls, patients showed significantly decreased volume in the grey matter of the right putamen, the left putamen, the left insula (numbers of voxel in clusters were 455, 561, 162, t=-9.5681,-5.9516,-5.7185,P<0.001, AlphaSim-corrected). There was negative correlation between decreased grey matter volume of the right putamen[(0.53 ± 0.12)mm3]and the left putamen[(0.48 ± 0.12)mm3] and dialysis duration [19.0(1.5-114.0)months] (r=-0.330,-0.307,P<0.05). MMSE score of patients[29(21-30)score] was significantly lower than normal controls[30(28-30)score] (Z=-30.58,P<0.01). Decreased grey matter volume of the left insula [(0.39 ± 0.12) mm3] was positively correlated with MMSE(r=0.320, P<0.05). Conclusions The patients with maintaining hemodialysis show grey matter atrophy which is associated with neurocognitive dysfunction. Dialysis duration may be an important risk factor for decreased gray matter in patients with maintaining hemodialysis.
RESUMO
Objective To evaluate the distribution and age-related changes of brain iron content in healthy people using MR quantitative susceptibility mapping (QSM).Methods Sixty three healthy right-handed volunteers underwent the routine MRI and SWI scan to get SWI-unfiltered phase images and magnitude images.QSM were reconstructed from the SWI-unfiltered phase images and magnitude images using SMART software.The regions of interest at the bilateral frontal white matter and nuclei (caudate nuclews,globus pallidus,putamen,substantia nigra,dorsal thalamus,red nucleus and dental nucleus) were drawn manually,and the susceptibility was measured.The linear correlation between the susceptibility and iron concentration cited from Hallgren and Sourander's post-mortem brain study was calculated.Wilcoxon test were applied to calculate the difference between the bilateral frontal white matter and bilateral nuclei.The correlation of age with susceptibility of bilateral frontal white matter and bilateral nuclei were analyzed by Spearman correlation analysis.Results The median susceptibility (extent) of frontal white matter,caudate nucleus,globus pallidus,putamen,dorsal thalamus,substantia nigra,red nucleus and dentate nucleus of 63 healthy people were-12.81 (-31.56,8.72),39.27 (22.35,75.13),93.99 (19.19,158.75),29.16 (4.11,81.53),2.91 (-27.80,27.95),83.14 (38.57,185.79),63.49 (13.83,142.09),63.30 (36.78,128.53) ppb (× 10-9),respectively.There was high consistency with Hallgren and Sourander's study (r=0.91,P<0.05).The susceptibility of globus pallidus was the highest,followed by substantia nigra.The least susceptibility was seen in the frontal white matter.The susceptibility of right caudate nucleus,substantia nigra,red nucleus and dental nucleus was higher than that of left side (Z value was-3.18,-4.44,-3.70 and-2.64,respectively,P<0.05).The susceptibility of bilateral globus pallidus of the male was significantly different from that of the female (Z value was-2.27 and-2.42,respectively,P<0.05).There was positive correlation between age and the susceptibility of bilateral caudate nucleus,putamen,red nucleus and dental nucleus (r value was 0.30 to 0.49,P<0.05).Conclusions QSM based on the SWI-unfiltered phase and magnitude images can clearly display the cerebral nuclei and evaluate the brain iron content accurately,which is consistent with the histopathological results.Iron content of bilateral caudate nucleus,putamen,red nucleus and dental nucleus increase with aging.

<p><b>OBJECTIVE</b>To compare the efficacy between perioperative enteral and parenteral nutrition support for esophageal cancer patients complicated with diabetes mellitus.</p><p><b>METHODS</b>Thirty esophageal cancer patients complicated with diabetes mellitus between September and November 2012 were prospectively enrolled in this trial. According to random number table, 30 cases were randomly divided into enteral group (n=15) and parenteral group (n=15). During the period between 3 days before operation and 8 days after operation, patients received enteral nutrition (AnSure) and parenteral nutrition support respectively. The daily dynamic monitoring of blood glucose was performed. Nutritional indexes (albumin and prealbumin) were evaluated 1-day before operation and 8-day after operation. Postoperative recovery time of gastrointestinal function and complications associated with nutritional support were observed. The cost of nutritional support was calculated.</p><p><b>RESULTS</b>Patients in the two groups achieved satisfactory perioperative blood glucose control. Finger tip blood glucose was 5.0-9.0 mmol/L before meal, 7.0-10.0 mmol/L 2-hour after meal, and 4.0-8.0 mmol/L at 10 PM and 3 AM. No hypoglycemia (<3.5 mmol/L) was found in all the patients. The time to first flatus after surgery was (62.4±15.7) in the enteral group, significantly earlier than (90.8±22.4) h in the parenteral group (P<0.01). Postoperative nutritional indices and associated complications were not significantly different between two groups (all P>0.05). Cost in the enteral group was significantly lower than that in the parenteral group [(650.8±45.8) RMB vs. (3016.5±152.6) RMB, P<0.01].</p><p><b>CONCLUSION</b>Perioperative nutrition support can effectively control blood glucose and improve perioperative nutritional status simultaneously for esophageal cancer patients with diabetes mellitus. Compared with parenteral nutrition, enteral nutrition can accelerate the recovery of gastric bowel function and reduce the cost of nutritional support.</p>

Licorice, the oldest Chinese traditional medicine, is widely used in the treatment of human diseases. Due to the deficiency of wild resource, selecting and breeding becomes a key issue to expanding the supply of licorice. Spaceflight technology will become a new method for medicinal plants. The aim of this study was to investigate the effect of spaceflight on the components and anti-inflammatory activity in licorice. After flowing on a recoverable satellite for 18 days, licorice seeds were germinated and grown to maturity and the parallel ground-based seeds were also planted under the same conditions. The main components in licorice root were analyzed through HPLC. The contents of two components in spaceflight groups were higher than that of the ground control ones. Three acute inflammatory models including xylene-induced auricular edema, carrageenan-induced paw edema and acetic acid-induced vascular permeability were utilized to compare the anti-inflammatory activity of licorice pre and post spaceflight. The licorice extract showed the significant anti-inflammation activity. After the spaceflight, the pharmacological activity of licorice got higher than that of the ground control one. All of the models gained the tendency that the spaceflight group of species Hangjinqi had the strongest activity than other groups. The research provided the scientific data for a new breeding of medicinal plant through the spaceflight and indicated that the technology of space flight may be a new effective method for the breeding and cultivation of licorice

<p><b>OBJECTIVE</b>To investigate the feasibility and safety of minimally invasive esophagectomy (MIE) for esophageal carcinoma.</p><p><b>METHODS</b>Clinical data of 298 esophageal carcinoma cases who were treated by MIE in the Fujian Provincial Cancer Hospital from June 2008 to April 2012 were retrospectively reviewed.</p><p><b>RESULTS</b>All the patients underwent MIE successfully except one conversion to open surgery. The mean operative time was (242.3±58.7) min. The postoperative length of hospital stay was (17.4±9.8) d. The number of harvested lymph nodes of total, the mediastinum, the abdomen and the cervix was 27.5±12.2, 10.7±5.7, 13.3±7.8, and 7.7±8.1, respectively. Postoperative complication rate was 29.9%, including pneumonia (n=41), recurrent laryngeal nerve injury (n=25), anastomotic leak (n=9), wound infection (n=7), and others (n=7). After follow up of 2 to 47 months, 3 patients were found to develop anastomotic stricture. There were no recurrence, metastasis, or death.</p><p><b>CONCLUSION</b>Minimally invasive esophagectomy is a safe, feasible, effective and minimally invasive surgical technique.</p>

Space breeding in medicinal plants is special characteristics in China. Compared with other plants, in spite of a relatively small number, Medicinal plants have more obvious characteristics and advantages. Research on medicinal plants has also been carried into all aspects, such as biological traits, physiology and biochemistry, genomics, as well as differences in chemical composition, and chemical composition analysis is also involved. However, compared with other plants, especially crops and vegetables, biological research is an obvious deficiency, that is mainly reflected in the insufficient genetics and breeding researches, the stability of genetic traits from generation to generation were not followed up and in-depth study in breeding areas was not carried out. If medicinal plants resources from space with the genetic stability good quality were selected, it would address the problem of lack of resources and ease the pressure on wild resources of medicinal plants. It would at the same time play an important role in promoting the development of medicinal botany space breeding and the implementation of modernization of traditional Chinese medicine.

<p><b>OBJECTIVE</b>To investigate the space environment on the role of licorice mutagenesis analysis of proteins.</p><p><b>METHOD</b>Licorice (Glycyrrhiza uralensis) seeds were carried by a recoverable satellite for 18 days (the average radiation dose in the flight recovery module was 0.102 m x d(-1), the orbit semidiameter 350 km, gravity 10(-6)). After return, The satellite-flown seeds and the unflown seeds (ground control) were planted in the fields of experimental farm. The leaves of each group were used for studying the effects of space flight on CAT, SOD activity, the protein content and electrophoresis.</p><p><b>RESULT</b>After the space flight, CAT, SOD activity of licorice increased in varying degrees, the difference was significant (P<0.05), two types of enzyme activity of sample from Ordos were higher than that from Hangjinqi. The protein content of licorice increased in a certain extent, the difference was significant (P<0.05), while protein electrophoresis also showed differences, weak new bands appeared.</p><p><b>CONCLUSION</b>These results indicated that spaceflight has effect on protein of licorice, these changes may be used as a tool for accelerating the progress in G. uralensis breeding.</p>
