Objective:
To investigate the factors associated with the patient's adherence to screening in the five years before the diagnosis of hepatocellular carcinoma (HCC) related to chronic hepatitis B ( CHB ), so as to provide reference for improving the screening rate.
Methods:
From June 2016 to April 2018, the patients with newly diagnosed HCC and a history of CHB for more than five years in Southwest Hospital in Chongqing were interviewed. The information about socio-demographic characteristics, health status, medical care and HCC screening in the past five years were collected. A multivariate logistic regression model was used to analyze the factors associated with adherence to screening.
Results:
Among 420 participants, 140 ( 33.33% ) adhered to HCC screening, 124 ( 29.53% ) had irregular/incomplete screening, while 156 ( 37.14% ) never had screening. The proportion of early-stage HCC at diagnosis was significantly higher in patients who adhered to screening ( 77.14% ) than that in patients who had irregular/incomplete screening (35.48%) or no screening ( 12.82% ) and the differences were statistically significant ( P<0.05 ). The multivariate analysis demonstrated that five factors were significantly associated with patient's adherence to screening, including education level of high school and above ( OR=2.346, 95%CI: 1.370-4.017), family history of HCC ( OR=2.795, 95%CI: 1.457-5.362 ), history of chronic diseases ( OR=3.860, 95%CI: 2.052-7.262), acceptance of antiviral therapy ( OR=17.816, 95%CI: 9.702-32.716 ) and specialized clinic visits ( OR=8.332, 95%CI: 1.588-43.710 ).
Conclusions
Adherence to screening is conducive to the early detection of HCC, but the screening rate is low in the patients with CHB. Education level, history of HCC, health status and medical status are significantly related to screening adherence.

Abstract: Objective To analyze a case of bloodstream infection caused by Ureaplasma urealyticum after abortion in Anxi County Hospital, so as to provide basis for the clinical diagnosis and treatment. Methods The diagnosis of Ureaplasma urealyticum in this patient with bloodstream infection was retrospectively analyzed. The basic clinical data and laboratory diagnosis data were collected, including the characteristics of blood culture curve, Wright staining of culture medium, drug sensitivity of Mycoplasma liquid identification, colony characteristics of solid medium, and the conclusion of targeted DNA sequencing. Through the comprehensive analysis of the above data, the rapid diagnosis of this case can be realized by optimizing the detection and diagnosis process. Results The clinical manifestations of this patient were fever of 38.5 ℃, CRP:14.85 mg/L, WBC:14.33×109/L, NET: 85.40%, PCT: 0.12 ng/mL, IL-6: 665.6 pg/mL, positive after 3 days of blood culture, no bacteria were found in Gram stain, and sand-like purple bacteria were observed after adding Wright's stain. After inoculation in blood agar, Mycoplasma solid and liquid medium, no colonies were grown in blood agar, after 48 h and 5 d. On Mycoplasma A7 agar, the edge of brown fried egg colony was striature, and it could be identified as Ureaplasma urealyticum with the Mycoplasma ID & AST panel, which was resistant to quinolones and spectinomycin, but sensitive to macrolides, tetracyclines and lincomycin. Subsequent targeted DNA sequencing results were also confirmed for Ureaplasma urealyticum. Before receiving the report, clinical experience treatment with ceftriaxone metronidazole was used to fight infection with negative bacilli and anaerobic bacteria. Mycoplasma was not treated with targeted treatment. After 3 days, the patient's body temperature returned to normal, inflammation index decreased, and the patient asked to be discharged. Conclusions At present, there are few reports of bloodstream infection caused by Ureaplasma urealyticum, and the lack of clinical understanding can easily lead to misdiagnosis and missed diagnosis. In order to improve the detection rate of Mycoplasma in blood culture, it is necessary to optimize the detection procedure of blood culture and provide accurate diagnosis and treatment basis for clinical practice. However, it is clear from this case that Mycoplasma bloodstream infection cases are self-limited infection and can recover by themselves without targeted treatment in patients with normal immunity. Therefore, it is very important to protect the immunity of patients.

Objective To study the relationship between metabolic syndrome (MS) and anterior circulation infarction (ACI). Methods 271 ACI patients (166 men and 105 women) who fulfilled the diagnostic criteria of China Guideline for Cerebrovascular Disease Prevention and Treatment were enrolled. 147 control subjects (67 men and 80 women) without the clinical signs of cerebral infarction but with detailed case history, physical examination and CT or MRI were also selected. The prevalence and risk of MS were observed in the ACI and control group. MS was defined with the modified criteria in Chinese. Results The prevalence of MS in the ACI group and control subjects was respectively 43.17% and 19.05%. The prevalence of MS was significantly higher in the ACI group as compared with the control subjects (P<0.01). The component level of MS were significandy different between the two groups (P< 0.05). MS was associated with a 3.7 fold higher risk of ACI (P<0.01). Conclusions There is a close relationship between MS and ACI. MS is an important risk factor of ACI.

Curcumin-ethyl-cellulose (EC) sustained-release composite particles were prepared by using supercritical CO2 anti-solvent technology. With drug loading and yield of inclusion complex as evaluation indexes, on the basis of single factor tests, orthogonal experimental design was used to optimize the preparation process of curcumin-EC sustained-release composite particles. The experiments such as drug loading, yield, particle size distribution, electron microscope analysis (SEM) , infrared spectrum (IR), differential scanning calorimetry (DSC) and in vitro dissolution were used to analyze the optimal process combination. The orthogonal experimental optimization process conditions were set as follows: crystallization temperature 45 degrees C, crystallization pressure 10 MPa, curcumin concentration 8 g x L(-1), solvent flow rate 0.9 mL x min(-1), and CO2 velocity 4 L x min(-1). Under the optimal conditions, the average drug loading and yield of curcumin-EC sustained-release composite particles were 33.01% and 83.97%, and the average particle size of the particles was 20.632 μm. IR and DSC analysis showed that curcumin might complex with EC. The experiments of in vitro dissolution showed that curcumin-EC composite particles had good sustained-release effect. Curcumin-EC sustained-release composite particles can be prepared by supercritical CO2 anti-solvent technology.

OBJECTIVETo explore the genetic basis of using three species of Asarum as Herba Asari to determine the taxonomic positions of Asarum heterotropoides and A. siebodii; and to apply DNA molecular analysis as a tool for identification of Herba Asari.
METHODPCR, purification, sequence analysis were prerformed.
RESULTMS sequences of the three Asarum species were obtained. 3 botanical sources of Herba Asari are closely clustered together on the topology tree; one inner branch is composed of A. heterotropoides and A. sieboldii, whereas another branch contains A. sieboldii. Their ITS sequences are different.
CONCLUSIONThree plant species of Herba Asari are closely related, and there are genetic reasons that they are used as the sources of the same medicine. The classification placement of A. sieboldii is not certain. The differences of ITS sequences of the botanical sources of Herba Asari can be used as a means of identification.
