Objective To investigate the relationship between multi-slice spiral CT perfusion imaging and tumor angiogenesis and cell cycle protein D1 (cyclinD1) expression in patients with peripheral lung cancer. Methods Seventy-three patients with peripheral lung cancer underwent 16-slice spiral CTperfusion imaging. The CT perfusion imaging were analyzed for time density curve (TDC), perfusion parametric maps and the respective perfusion parameters (BF, BV, PS, PH, and PHpm/PHa). Correlation between the respective perfusion parameters and immunohistochemical findings of MVD measurement and cyclinD1 expression were evaluated. Statistical method used one factor analysis of variance (One-wayANOVA) and Pearson correlation analysis. Results The shape of TDC of three groups of peripheral lung cancers (adenocarcinoma, squamous cell carcinoma, and other type of cancer) was similar. They showed a steeper slope, was obvious increase of nodular HU value [ peak height of TDC is respectively (44. 87±6. 83), (34. 91 ± 8.05), (40. 66±5. 87) HU ], changed little after reaching peak height, became flat at peak, had a platform. Forty-four patients were cyclinD1 positive expression, the peripheral lung cancers with cyclinD1 positive expression showed significantly higher MVD value than that of the peripheral lung cancers with cyclinD1 negative expression [ respectively (33.88± 14. 81), (23. 17±11.66) band/high magnification, P < 0. 01]. The cancers with cyclinD1 positive expression showed significantly higher PH,PHpm/PHa, BF,BV, PS value than those of the cancers with cyelinD1 negative expression[respectively P <0. 05]. MVD was positively correlated with PH, PHpm/PHa, BF, BV, and PS of the three groups ofcancers with cyclinD1 positive expression. Among, the correlation coefficient (r value) of BV, PS, BF was0. 409, 0. 517,0. 503 respectively(all P < 0. 01). MVD was significantly correlated with them. The r valueof PH, PHpm/PHa is 0. 319,0. 324 respectively(all P < 0. 05). MVD was less correlated with them. MVDwas not correlated with PH, PHpm/PHa, BF, BV, and PS of the three groups of cancers with cyclinD1 negative expression. Conclusions Multi-slice spiral CT perfusion imaging moderately correlated with tumorangiogenesis and reflected MVD measurement and cyclinD1 expression. It provided not only a noninvasive method of quantitative assessment for blood flow patterns of peripheral lung cancer but also an applicable diagnostic method for peripheral lung cancer.

PrME and NS1 gene were the two main immuneprotect proteins of Japanese encephalitis virus (JEV), and they were also N-linked glycosylation proteins. To clear the effect of N-glycosylation on JEV immunity, the N-glycosylation site of prME and NS1 gene were eliminated by site-directed mutant PCR, subtituting the N to Q. And the the mutant genes were subcloned into eukaryotic expression plasmid. Four-weeks female mice were immuned with the wildtype and mutant gene by twice. The antibodies against prME were detected by ELISA and the neutralization antibodies were tested by viral neutralizing assay. The immunoprotection were determined by attack with JEV virulent strain. Compare with the wild-type gene immuned-groups, one N-glycan eliminated prME gene could induce a little higher ELISA antibody, neutralization antibody and immunoprotection, but the immunity of gene with both N-glycan absence was decreased. The similar status were observed in the wildtype and mutant NS1 groups. Thus these results show that the N-linked glycosylation in the prME and NS1 gene were correlated with the immunity, one glycan absent would enhance the immunity but both two loss would impair it.

Three cases of flagellate shiitake mushroom dermatitis caused by Pleurotus ostreatus, Auricularia auricula, and Flammulina velutipes respectively were reported. Case 1, a 45-year-old male patient, developed multiple flagellate erythematous patches and papules on the trunk, axillae and abdomen without any subjective discomfort 8 hours after ingestion of a large amount of grilled Pleurotus ostreatus. Case 2, a 33-year-old female patient, developed multiple flagellate erythematous patches with mild swelling and itching on the back 1.5 days after consuming a fresh Auricularia auricula salad, and millet-sized papules were densely distributed on the erythematous patches. Case 3, a 54-year-old female patient, developed cord-like, flagellate edematous erythema and papules on the neck, trunk and proximal extremities 72 hours after consuming Flammulina velutipes. Histopathological examination of the dorsal lesions in case 3 showed epidermal spongiosis, intraepidermal blisters, papillary dermal edema, superficial dermal vasodilation, erythrocyte extravasation, inflammatory infiltration composed mainly of lymphocytes around dilated blood vessels, and a few scattered eosinophils. The 3 patients were all diagnosed with flagellate shiitake mushroom dermatitis. Case 1 received no treatment, while cases 2 and 3 were symptomatically treated with topical fluticasone propionate ointment, and achieved recovery of skin lesions after 1 week.

Recombinant baculovirus containing sigmaC gene of Avian reovirus was constructed using Bac-To-Bac Baculovirus expression system, and recombinant sigmaC protein was expressed by infecting the sf9 cell with recombinant baculovirus. Firstly, sigmaC gene of Avian reovirus was cloned and inserted into donor plasmid pFastBacHTA to obtain recombinant donor plasmid pFsigmaC. Plasmid pFsigmaC was transformed into E. coli DH10Bac for integration into bacmid vector and the recombinant bacmid plasmid BacmidsigmaC was obtained. Recombinant baculovirus rBacsigmaC was obtained by transfection of the sf9 cells with BacmidsigmaC. Western blot and indirect immunofluorescence assay (IFA) were carried and the results showed that the recombinant sigmaC protein with 37 kDa molecular weight was expressed successfully.

BACKGROUNDThe clinical outcome of percutaneous coronary intervention (PCI) is poorer in women than that in men. This study aimed at comparing the impact of gender difference on the strategy of primary PCI in patients with acute ST-segment elevation myocardial infarction (STEMI).
METHODSTwo hundred and fifty-nine patients with STEMI who underwent primary PCI within 12 hours of symptom onset were enrolled. The male group consisted of 143 men aged > 55 years, and a female group included 116 women without age limitation. Procedural success was defined as residual stenosis < 20% with thrombolysis in myocardial infarction flow grade > 2 and without death, emergency bypass surgery or disabling cerebral events during the hospitalization. The rate of major adverse cardiac events (MACE), including death, nonfatal myocardial infarction and target vessel revascularization during follow-up, was recorded.
RESULTSFemale patients were more hypertensive and diabetic and with fewer cigarette smokers than male counterparts. The prevalence of angiographic 3-vessel disease was higher in the female group, but the procedural success rate was comparable between the two groups (94.4% vs 92.2%). The occurrence rate of MACE did not differ during the hospitalization (4.2% vs 6.0%, P = 0.50), but was significantly higher in the female group during follow-up (mean (16.0 +/- 11.2) months) than that in the male group (5.4% vs 0.7%, P = 0.02).
CONCLUSIONDespite a similar success rate of primary PCI and in-hospital outcomes in both genders, female patients with acute STEMI still have a worse prognosis during the long-term follow-up.

OBJECTIVETo investigate associations between health-promoting lifestyle and suboptimal health status (SHS) in the population of Guangdong province.
METHODSA cross-sectional survey was conducted in a clustered sample of 24 159 individuals aged 12-80 years from 2012 to 2013. Health-promoting lifestyle was assessed via the Health-Promoting Lifestyle Profile (HPLP-II), and SHS was evaluated using the medical examination report and Sub-health Measurement Scale V1.0 (SHMS V1.0).
RESULTSOf the 24159 participants, subjects with SHS (46.0%) and disease status (35.2%) accounted for a much higher percentage than healthy subjects (18.8%). Regression analyses revealed a significant association between health status and healthy lifestyle (P<0.001). Unhealthy lifestyle was an important risk factor for SHS and disease, especially the former. Compared with the participants with a healthy lifestyle (minimal exposure), after demographic adjustment, subjects with a 'poor' lifestyle (maximal exposure) were at a 43 times higher risk of developing SHS (OR: 42.825, 95% CI: 30.567-59.997), those with a general lifestyle were at a 21 times higher risk of SHS (OR: 21.072, 95%CI: 17.258-25.729), and those with a suboptimal lifestyle had a 4 times higher risk (OR: 4.085, 95%CI: 3.352-4.979). In the general population, the major risk factors for SHS included poor stress management, poor self-actualization, inactive exercise and poor interpersonal relationship.
CONCLUSIONs Unhealthy lifestyles are significantly related to an increased risk of SHS. Intervention of unhealthy lifestyles, controlling the risk factors of SHS, and rigorous management of the time window of SHS are necessary to promote the heath status.

Objective:To investigate the safety and dose of 4D template (real-time adjustable angle template) in the treatment of advanced malignant tumors with 125I seeds. Methods:98 patients with advanced malignant tumors admitted to Department of Thoracic Surgery of Shaanxi Provincial Tumor Hospital were treated with 4D template-navigated radioactive 125I seed implantation from June 2018 to December 2019. Preoperative TPS plan, intraoperative optimization, postoperative verification of immediate dose and postoperative evaluation of implantation dose were performed. The treatment results were observed. Results:All 98 patients completed the seed implantation. The implantation dose of GTV of implantation site receiving external irradiation was (12 489±414) cGy and the dose of no external irradiation was (15 036±514) cGy. V 100% was 84.7%-94.1%, and 88.2%-93.7%. The implantation dose of CTV was (7 450±621) cGy, and (9 080±761) cGy. The quality of dose implantation was evaluated as: excellent in 89 cases (91%, 89/98), good in 7 cases (7%, 7/98), fair in 2 cases (2%, 2/98), and poor in 0 case, respectively. The symptom relief rate of patients with pain was 92%(36/39). The 1-and 2-year local control rates were 61%, 36% and 82%, 54% in patients treated with and without external irradiation, respectively. The difference was statistically significant ( P=0.02). The incidence rates of pneumothorax and hemoptysis were 19%(9/48) and 10%(5/48). No corresponding complications were observed in other parts of the patients. Conclusion:4D template-assisted 125I seed therapy is safe and effective for malignant tumors, and intraoperative adjustment of needle angle and dose optimization can realize the precise control of implantation dose.

Background/Aims:
Chronic hepatitis B (CHB) and fatty liver (FL) often co-exist, but natural history data of this dual condition (CHB-FL) are sparse. Via a systematic review, conventional meta-analysis (MA) and individual patient-level data MA (IPDMA), we compared liver-related outcomes and mortality between CHB-FL and CHB-no FL patients.
Methods:
We searched 4 databases from inception to December 2021 and pooled study-level estimates using a random- effects model for conventional MA. For IPDMA, we evaluated outcomes after balancing the two study groups with inverse probability treatment weighting (IPTW) on age, sex, cirrhosis, diabetes, ALT, HBeAg, HBV DNA, and antiviral treatment.
Results:
We screened 2,157 articles and included 19 eligible studies (17,955 patients: 11,908 CHB-no FL; 6,047 CHB-FL) in conventional MA, which found severe heterogeneity (I2=88–95%) and no significant differences in HCC, cirrhosis, mortality, or HBsAg seroclearance incidence (P=0.27–0.93). IPDMA included 13,262 patients: 8,625 CHB-no FL and 4,637 CHB-FL patients who differed in several characteristics. The IPTW cohort included 6,955 CHB-no FL and 3,346 CHB-FL well-matched patients. CHB-FL patients (vs. CHB-no FL) had significantly lower HCC, cirrhosis, mortality and higher HBsAg seroclearance incidence (all p≤0.002), with consistent results in subgroups. CHB-FL diagnosed by liver biopsy had a higher 10-year cumulative HCC incidence than CHB-FL diagnosed with non-invasive methods (63.6% vs. 4.3%, p<0.0001).
Conclusions
IPDMA data with well-matched CHB patient groups showed that FL (vs. no FL) was associated with significantly lower HCC, cirrhosis, and mortality risk and higher HBsAg seroclearance probability.
