Objective To investigate the value of echocardiography in monitoring the treatment of extracorporeal membrane oxygenation (ECMO) in patients with cardiogenic shock (CS).Methods A total of 21 patientss were included into the present study,who were treated by ECMO due to CS in Wuhan Asia Heart Hospital from January 2013 to December 2015.The left ventricular ejection fraction (LVEF) and Tei index were measured by echocardiography before,in the middle of (flow reduced to one half)and immediately after the process of ECMO.The systolic blood pressure (SBP) and the arterial oxygen saturation (SaO2) were also recorded,and the parameters were compared.The differences of LVEF,Tei index,SBP and SaO2 among different phases of ECMO were compared by using one-way ANOVA and LSD-t test.The differences of heart beat rate,the diameters of left ventricle,diameters of inferior vena cava,subsidence rate of inferior vena cava,pulmonary capillary wedge pressure and central venous pressure among different phases of ECMO were also compared by paired-samples t test.Results Compared with the pre-ECMO level,the LVEF increased during and immediately after the ECMO (t=31.952,59.404,both P ＜ 0.01),while the Tei index decreased significantly (t=34.406,58.969,both P ＜ 0.01).Compared with the pre-ECMO level,the SBP,SaO2 and subsidence rate of inferior vena cava all increased during and immediately after the ECMO,while the diameter of left ventricle,pulmonary capillary wedge pressure and central venous pressure all decreased significantly (t=7.382,37.785,-11.286,3.294,13.923,16.971,all P ＜ 0.01 or 0.05).In contrast,there was no significant change for the parameters of heart beat rate and diameter of inferior vena cava.Conclusion When treating CS patients with ECMO,the echocardiography can monitor the cardiac function effectively,and provide important parameters for the clinical doctors to estimate the ECMO efficacy and decide the weaning time.

Cassiae Semen is a common traditional Chinese medicine, and contents of anthraquinones of Cassiae Semen different significantly from area to area. According to Chinese Pharmacopoeia (2010 edition), only contents of aurantio obtusin and chrysophanol were used to evaluate the quality of Cassiae Semen, another data could be added later. Ten batches of Cassiae Semen from different areas were determined, and total anthraquinones, total free anthraquinones and total combined anthraquinones contents were assessed by ultraviolet visible spectrophotometer, contents of aurantio obtusin, rhein, aloe emodin, emodin, chrysophanol and physcion were determined by HPLC. After that, principal components analysis was used to evaluate these data determined previous by dimension reduction analysis. At last, the result suggests that three main components were found out, it shows that content of aloe emodin could be used to evaluate the quality of Cassiae Semen as well as contents of aurantio obtusin and chrysophanol. And Cassiae Semen from Hebei province posseses higher quality than Cassiae Semen from other different areas. All these results can provide a good reference for quality evaluating of Cassiae Semen medicinal materials at a certain extent.

Objective According to the data collected from gastric cancer families comparative study, the influence factors of Hardy-Weinberg (H-W) equilibrium in the association studies of gene polymorphism and disease were analyzed to reveal the reasons that affecting the equilibrium deviation in the group. Methods Varieties of risk genotype for gastric cancer were analyzed and detected with H-W equilibrium, genetic linkage disequilibrium analysis and Cochran-Armitage trend test. Results (1) Significant deviations from H-W equilibrium were observed in IL-1B-31, IL-IB-511, IL-IRN and TNF-A-308 of the cases and controls (P<0.01). MIF-173 tended to be equilibrium in the population. (2)Deviations from expectations of phenotypes combination probability were observed in two-site H-W χ2 tests (P< 0.01). (3)The Cochran-Armitage trend test showed that distribution of IL-1B-511 and IL-1RN were significantly different(P<0.05), suggesting that population stratification might have existed in the group. Conclusions (1)Affected by frequency-dependent selection, under the combination of linkage disequilibrium, mutations and interaction, genotype frequency of IL-1B-31, IL-1B-511, IL-1RN and TNF-A-308 showed deviation from H-W equilibrium in population. (2)Two-site genetic equilibrium test model seemed better to reflect the differences of phenotypic combination fitness. (3)Population stratification was another factor to express the deviation from H-W equilibrium.

Flexible matching has recently been proposed as a method of improving interactions efficiency. In this study, the concept of flexible matching has been introduced, and the applicability of this strategy has also been described based on the power calculation of interaction between HER-2 polymorphism and smoking with breast cancer. A large-sample approximation method is used to estimate the power and efficiency of gene-environment interactions. In the basic scenario, power of interaction between HER-2 polymorphism and smoking of unmatched case-control study appears to be 30% while in the frequency matching case-control study it is 56%. However, when increasing the smoking prevalence in controls, greater power can be obtained (power=74%). Conclusions: Flexible matching strategies can increase the power and efficiency of case-control studies to detect and estimate the gene-environment interactions when compared with traditional frequency matching and it is especially useful under those scenarios when low environmental exposure of population, adverse gene-environment interactions or less paired controls are seen. Optimal matching design should be made available by weighing the benefits and loss due to flexible matching.

OBJECTIVEIBS-D rat model was established to assess the effect of Shen warming Pi strengthening method (SWPSM) for intervening diarrhea-predominant irritable bowel syndrome (IBS-D) by observing rats' general state, stool properties, AWR ranking, and histopathological changes.

METHODSTotally 72 rats were randomly divided into 6 groups, i.e. the normal group, the model group, the high, middle, low dose SWPSM groups, and the control group, 12 in each group. The IBS-D rat model was successfully established referring to AL-Chaer ED's modeling method. After modeling high, middle, and low dose SWPS Recipe boil-free granules were given by gastrogavage to rats in corresponding treatment groups. Sishen Pill boil-free granule was given by gastrogavage to those in the control group. Equal volume of normal saline was given by gastrogavage to rats in the model group. The medication lasted for 2 weeks. Rats' general state, stool properties, abdominal withdrawal reflex (AWR) ranking, and histopathological changes were observed.

RESULTSAfter treatment, the general state of all rats got im- provement to various degrees. The improvement in the high and middle dose SWPS Recipe groups were superior to that in the low dose SWPS Recipe group and the control group (P < 0.05). There was no statistical difference in the growth rate between after and before treatment in each group (P > 0.05). Compared with the model group and the low dose SWPS Recipe group, the defecation amount within 4 h was less in the high and middle dose SWPS Recipe groups and the control group (P < 0.05). The Bristol ranking score, average ranking of loose stool, ratio of dry stool and wet stool were lower in the high and middle dose SWPS Recipe groups than in the control group and the low dose SWPS Recipe group (P < 0.05). The AWR ranking score was lower in the high and middle dose SWPS Recipe groups than in the control group when the volume of balloon dilation was 1.5 mL. There was no organic change of histological or morphological observation.

CONCLUSIONSHigh sensitive IBS-D model was proved to be reliable. SWPSM could reduce the quantity of stools, lower Bristol ranking score, average ranking of loose stools as well as ratios of dry stool and wet stool, contributing to reducing the high sensitivity of rats' visceral organs to some extent.

Abstract: Objective　To collect and organize malaria case data in Hubei Province from 2017 to 2021, compare and analyze the malaria epidemic characteristics on the before and after malaria elimination, and provide scientific support for Hubei Province to further optimize the comprehensive strategies to prevent re-transmission after the elimination of malaria. Methods The study was conducted by collecting the data of reported malaria cases of Hubei during 2017-2021 from the Infectious Disease Surveillance Reporting and Management System, and conducting the epidemiological characteristics of malaria on pre-elimination (2017-2019) and post-elimination (2020-2021). Results A total of 429 cases of imported malaria were reported in Hubei Province from 2017 to 2021, and the malaria epidemic showed an obvious trend of rising first and then falling. On the pre-malaria elimination, 374 malaria cases were reported, including 262 cases of P.falciparum (70.05%); on the post-malaria elimination, 55 malaria cases were reported, including 25 cases of P.falciparum (45.45%). There was a statistically significant difference in the proportion of infections caused by the four types of malaria parasites before and after the elimination of malaria (χ2=14.248, P<0.05). On the pre-malaria elimination, the peak of disease onset mainly occurred in January, July, and November; on the post-malaria elimination, the peak of disease onset mainly occurred in January to February, and December. Both before and after malaria elimination, the reported cases were mainly concentrated in Wuhan, Yichang, Huangshi, Xiangyang, Shiyan and Huanggang, but the range of cases showed a clear trend of narrowing. Before and after malaria elimination, malaria cases in Hubei Province were mainly among young and middle-aged males aged 30-49. The proportions of workers and migrant workers increased from 37.70% and 9.09% before the elimination to 50.91% and 18.18% after the elimination, respectively, with a statistically significant difference (χ2=17.839, P<0.05). The percentage of interval from onset of illness to initial diagnosis ≥ 5d decreased from 21.66% before the elimination to 10.91% after the elimination (χ2=6.448, P<0.05). The percentage of definitive diagnosis of malaria at initial diagnosis in town clinic increased from 18.18% before the elimination to 50.00% after the elimination. The proportion of malaria cases diagnosed by county-level medical institutions increased from 22.73% before the elimination to 34.55% after elimination. There was no statistically significant difference in the proportion of malaria cases diagnosed by medical institutions at all levels before and after the elimination of malaria (χ2=5.630, P>0.05). The proportion of cases with the interval between initial diagnosis and diagnosis within 24h increased from 43.85% before the elimination to 70.91% after the elimination. There was a statistically significant difference in the proportion of cases with the interval between initial diagnosis and diagnosis before and after the elimination of malaria (χ2=14.006, P<0.05). Before and after malaria elimination, all reported cases were mainly imported from African countries. Conclusions There are imported malaria cases reported every year in Hubei Province before and after the elimination of malaria, which poses a great challenge to the prevention of re-transmission. Therefore, it is necessary to strengthen the surveillance system, detect and standardize the treatment of imported malaria cases in a timely manner, conduct targeted retransmission risk surveys and assessments, and consolidate the achievements of malaria elimination.
