Commensal microorganisms that colonize barrier surfaces of all multicellular organisms exist in harmony with their hosts and have an important effect on both immune and non-immune functions of their hosts. Numerous researches have shown that gastrointestinal microbiota being one of the most important commensal microorganisms plays a critical role in the occurrence, development and treatment of cancer. As-signing causal roles in cancer to specific microbes and microbiotas, unraveling host-microbiota interactions with environmental factors in carcinogenesis, and applying such knowledge to cancer diagnosis and treatment are areas of intensive interest. This review considers how microbes and the microbiota may amplify or miti-gate carcinogenesis, responsiveness to cancer therapeutics, and cancer-associated complications.

OBJECTIVE:
To perform morphometric analysis of bilateral cochleae in all subjects based on computed 3-dimensional reconstruction tomographic data and assist the surgeon in diagnosing the inner ear abnormality or surgical strategies.
METHOD:
Two hundred normal developed cochleae from 100 patients were divided into 5 groups according to age. Morphometric analysis of bilateral cochleae was performed in all subjects by 3D reconstructions and 2D multiplanar reformation. The length and width of the cochlear base, the length within the cochlear base, the height of the cochlea, the angle between the first and second turn of the cochlea, and the cochlear orientation within the cranial base were measured and compared in different age, sex and bilateral groups.
RESULT:
The length of the cochlear base was (8.56 +/- 0.52)mm, the width was (6.63 +/- 0.56)mm, the length within the cochlear base was (7.33 +/- 10.56)mm, the height of the cochlea was (3.76 +/- 0.28)mm, and the angle between the first and second turn of the cochlea was (15.82 +/- 2.78)degrees. All index above did not change significantly in different aging, sex or side (P > 0. 05). Variability in the angle between the first and second turn of the cochlea was considerable, and a smaller angle (from the midsagittal line) was showed in the older age groups than the younger groups (P < 0.05).
CONCLUSION
3D and 2D volume rendering enables us to evaluate the features of cochlear morphology and orientation that may assist the surgeon in diagnosing the inner ear abnormality or surgical strategies.

Abstract: Objective To explore the value of real-time shear wave elastography in evaluating the severity of liver fibrosis in hepatitis B, and to analyze the factors that affecting its accuracy. Methods A total of 196 chronic hepatitis B patients, who admitted to the Third Affiliated Hospital of Chengdu Medical College from February 2018 to October 2020, were selected for retrospective analysis. Demographic indicators such as gender, age, body mass index(BMI), and laboratory indicators such as fasting blood glucose, liver function, and blood lipid composition were collected. The patients were detected by real-time shear wave elastography. Taking the pathological test results as the gold standard, the diagnostic value of real-time shear wave elastography in the severity of liver fibrosis in chronic hepatitis B was analyzed, and the comprehensive effect of various factors on the diagnostic accuracy of real-time shear wave elastography was evaluated by Logistic regression analysis. Results The differences in real-time shear wave elastography of patients with different severity of liver fibrosis in hepatitis B were statistically significant, and F0 grade

Background Asthma is a complex disease involving genetic and environment interactions.Atopy is a strong risk factor for asthma.The airway epithelium not only forms a physical barrier but also provides immune defense against harmful materials.To explore the effects of airway epithelium on asthma,we hypothesized that environmental injuries could act on bronchial epithelial cells and damage the physical barrier,which might facilitate allergens to stimulate immunoreactions and play an important role in the pathogenesis of asthma.Methods Thirty eight-week-old male Wistar rats were randomly divided into five groups with six rats in each group:control group,asthma group,ovalbumin (OVA)+OVA group,lipopolysaccharide (LPS) group and LPS+OVA group.In the control group,0.9% saline was injected intraperitoneally on day 1.Fourteen days later,the rats were exposed to aerosolized 0.9% saline.In the asthma group,the rats were sensitized with an injection of 10 mg of OVA,followed by an aerosolized 2% OVA challenge14 days later.The OVA+OVA group was sensitized by an inhalation 2% OVA,20 minutes a day,from day 1 to day 7,and then OVA challenged in the same way as the asthma group.In the LPS group,LPS (200 μl,1 μg/μl) was given by airway on day 1 and day 3,with a simultaneous aerosol inhalation of 2% OVA for 20 minutes a day from day 1 to day 7.Fourteen days later,the rats were challenged with saline as in the control group.While in the LPS+OVA group,LPS (200 μl,1 μg/μl) was given by airway on day 1 and day 3,with a simultaneous aerosol inhalation of 2% OVA for 20 minutes a day from day 1 to day 7.Fourteen days later,the rats were challenged with OVA as in the asthma group.The expression of interleukin (IL)-4,interferon-gamma (IFN-y) and thymic stromal lymphopoietin (TSLP) in the lungs was detected by reverse transcription polymerase chain reaction (RT-PCR) and the pulmonary pathological changes were also observed.The level of IL-4,IFN-γ and IgE in plasma was detected by enzyme-linked immunosorbent assay (ELISA).Bronchoalveolar lavage fluid (BALF) was collected to conduct differential cell counts.Flow cytometry analysis was also used to count Th1 and Th2 cells.Results The pathological changes in the LPS+OVA group were similar to the asthma group,while in other groups,the pathological changes were not obvious.The ratio of lymphocytes in BALF,IL-4/IFN-γ in plasma and the expression of the TSLP and IL-4 in the asthma and LPS+OVA groups were higher than in the control group and the OVA+OVA group (P <0.05).The level of IgE was higher in the asthma,LPS and LPS+OVA groups than in the control group and the OVA+OVA group (P <0.05).By flow cytometry analysis,the Th1/Th2 ratio was lower in the LPS+OVA and asthma groups than in other groups (P <0.05).Conclusions The experiment results show that the injury to the bronchial epithelial layer may be the initial event of allergic responses.This finding implies that a rational approach to therapeutics would be to increase the resistance of the airways to environmental injuries rather than concentrating on suppressing inflammation.

Objective To assess the irregular shape of hematoma with math methods,which is one of the risk factors of hematoma enlargement.Methods We reviewed images data of patients with spontaneous intracerebral hemorrhage treated nonsurgically who underwent initial computed tomography (CT) within 6 hours and repeated CT within 48 hours of onset.The area(s),the circumference(L),the greatest diameter(A)and the transverse diameter(B)of the greatest hemorrhage CT slice was measured.The formula X=L/S waft used to calculate the value.We calculated the area(S1)and the circumference (L1) of the ellipse with A as its long diameter and B as its short diameter.The formula X1=S1/L1 was used to calculate the value. We used formula R=X/X1 to assess the irregular hematoma shape.The relationships between hematoma enlargement and R was analyzed. Results Thirty-one patients(25.8%) showed enlarged hematomas after admission.The larger the value of R,the more irregular the shape of hematoma.When R≥1.3,the shape of the hematoma was significantly irregular.36.0% patients with R≥1.3 had hematoma enlarged.compared with only 18.6% those with R<1.3(χ2=4.62,P=0.032).Conclusions The irregular shape index R Can be used to assess the shape of a hematoma. A particularly high likelihood of hematoma enlargement is observed in patients with an irregularly shape index R≥1.3.
