To explore the expression of heme oxygenase-1 (HO-1) in the peripheral blood mononuclear cells (PBMCs) and its relationship with pulmonary ventilation function in asthmatic patients, 18 asthmatic patients and 18 healthy subjects were selected. HO-1 protein and mRNA levels in PBMCs were measured by immunohistochemical staining and reverse transcription-polymerase chain reaction (RT-PCR), respectively. Blood carbon monoxide Hb (COHb), serum total IgE and pulmonary ventilatory function were observed. Our results showed that the percentage of cells positive for immunohistochemical staining of HO-1 were significantly higher in asthmatic patients (41.72 +/- 7.44) % than that in with healthy subjects (10.45 +/- 4.36) % (P < 0.001) and the optical density of PBMC HO-1 mRNA was higher in asthmatic patients (26.05 +/- 4.14) than that in healthy subjects (10. 82 +/- 4.26) (P < 0.001). The relation analysis showed that PBMC HO-1 protein and mRNA levels had significantly negative relation with FEV1%, PEFR, MEFR50%, respectively (r = -0.51-0.89, P < 0.05-0.001, respectively) and a positive relation with COHb and serum total IgE (r = 0.48-0. 85, 0.05-0.001, respectively). It is concluded that the expression of PBMC HO-1 protein and mRNA increased significantly in asthmatic patients, and HO-1 may play a significant role in the pathogenesis of asthma. The expression of HO-1 may bear a relation with severity of asthma.

Near infrared spectroscopy (NIR) was used to detect trans fatty acids (TFA) in edible vegetable oils quantitatively. And prediction model of TFA was optimized through band selection, pretreatment method, variable selection and modeling method. NIR spectra of 98 edible vegetable oil samples were collected in spectral range of 4000-10000 cm-1 using an Antaris Ⅱ Fourier transform near infrared spectrometer, and the true content of TFA was measured by gas chromatography. First, optimization of waveband and pretreatment method was conducted on original spectra. On this basis, competitive adaptive reweighted sampling (CARS) was used to select important variables that related to TFA. Finally, the prediction models of TFA content in edible vegetable oils were established using principal component regression ( PCR), partial least square (PLS) and least square support vector machine (LS-SVM). The results indicated that NIR spectroscopy was feasible for detecting TFA content in edible vegetable oils, R2 of the best prediction model after optimized in calibration and prediction sets were 0. 992 and 0. 989, and root mean square error of calibration (RMSEC) and root mean square error of prediction ( RMSEP) were 0. 071% and 0. 075% , respectively. Only 26 variables were used in the best prediction model, accounting for 0. 854% of the whole waveband variables. In addition, compared with the full waveband PLS prediction model, the R2 in prediction set increased from 0. 904 to 0. 989, and RMSEP decreased from 0. 230% to 0. 075% . It shows that model optimization is very necessary, CARS method can select important variables related to TFA effectively and immensely reduce the number of modeling variables, so it can simplify the prediction model, and greatly improve the accuracy and stability of prediction model.

ObjectiveTo investigate the clinical effect of Fuhe Beihua prescription combined with transcatheter arterial chemoembolization (TACE) in the treatment of primary liver cancer patients with liver depression and spleen deficiency and its effect on T lymphocyte subsets. MethodsA retrospective analysis was performed for the clinical data of stage Ⅲ primary liver cancer patients with liver depression and spleen deficiency who were treated in Department of Hepatology and Department of Oncology in The First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2018 to January 2020. According to whether the traditional Chinese medicine Fuhe Beihua prescription was used, the patients were divided into treatment group (treated with routine TACE and oral administration of Fuhe Beihua prescription) and control group (treated with routine TACE alone), and the course of treatment was 16 weeks for both groups. The two groups were compared in terms of short-term response rate, quality-of-life score, serum alpha-fetoprotein (AFP) level, four indicators of liver fibrosis, coagulation function parameters, peripheral blood T lymphocyte subsets, and liver function parameters. The independent samples t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. A repeated-measures analysis of variance was used for comparison of continuous data between different groups at different time points. ResultsA total of 218 patients were selected, with 118 in the control group and 100 in the treatment group. The treatment group had an objective response rate of 33% and a disease control rate of 66% at week 8 of treatment and an objective response rate of 34% and a disease control rate of 69% at week 16 of treatment, and the control group had an objective response rate of 26.27% and a disease control rate of 68.64% at week 8 of treatment and an objective response rate of 30.51% and a disease control rate of 68.64% at week 16 of treatment; there was a significant difference in objective response rate between the two groups at weeks 8 and 16 of treatment (P＜0.05). Both groups had significant increases in Karnofsky Performance Scale (KPS) score, fibrinogen, and albumin (Alb) from before treatment to weeks 8 and 16 of treatment (all P＜0.05), and there were significant differences in KPS score, fibrinogen, and Alb between the two groups at weeks 8 and 16 of treatment (all P＜0.05). Both groups had significant reductions in AFP, the four indicators of liver fibrosis, alanine aminotransferase (ALT), aspartate aminotransferase (AST), prothrombin time (PT), and traditional Chinese medicine (TCM) syndrome score after treatment (all P＜0.05), and at weeks 8 and 16 of treatment, there were significant differences between the two groups in AFP, the four indicators of liver fibrosis, ALT, AST, PT, and TCM syndrome score (all P＜0.05). At weeks 8 and 16 of treatment, the treatment group had significant increases in the levels of CD3+, CD4+, and CD4+/CD8+ (all P＜0.05) and a significant reduction in the level of CD8+ (P＜0.05), and there were significant differences in the levels of T lymphocyte subsets between the two groups at weeks 8 and 16 of treatment (all P＜0.05). ConclusionFuhe Beihua prescription combined with routine TACE has a better clinical effect than TACE alone in the treatment of primary liver cancer patients with liver depression and spleen deficiency, possibly by regulating the levels of T lymphocyte subsets.

Objective To establish mouse models of intracerebral hemorrhage using autologous arterial blood,to study the physiological property of hippocampal neurons,brain edema changes and learning ability in the mouse models after intracerebral hemorrhage.Methods Eighty male C57/BL6 mice were randomly divided into intracerebral hemorrhage group and control group (n=40); 20 μL arterial blood from the tail arteries or normal saline were injected into the caudate nucleus of intracerebral hemorrhage group and control group by stereotactic technique,respectively.One,three,five and seven d after injection,the neurological impairment was scored; the behavioral changes of the mice in the Morris water maze (navigation test and space exploration experiment) were observed; brain edema was measured by wet and dry weight method and electrophysiological differences of hippocampal neurons were recorded by whole-cell patch-clamp technique and computer software.Results As compared with those in the control group,significantly increased neurological deficit scores one,three,five and seven d after injection,statistically decreased residence time in the platform on the fifth d of training,obviously increased water content around the brain edema one,three,five and seven d after injection,and significantly decreased resting membrane potential and input resistance in the hippocampal CA1 pyramidal cells five d after injection of mice in the intracerebral hemorrhage group were noted (P＜0.05).Conclusion The hippocampus-dependent spatial leaming ability of intracerebral hemorrhage mice is decreased,and the permeability of potassium channels is enhanced.

BACKGROUNDIt was reported that telomerase expression is closely associated with cellular immortality and cancer. This study was designed to investigate the relationship between telomerase expression and the carcinogenesis of cervical cancer, the possible use of telomerase as a marker of cervical intraepithelial neoplasia (CIN) progression or regression, and the natural history of CIN.

METHODSTelomeric repeat amplification protocol (TRAP) assay was used to measure telomerase activity in cervical scrapings and biopsy samples obtained from 105 cases affected with various cervical conditions, including chronic cervicitis (n = 20), CIN (n = 64, 16 cases of CIN I, 20 cases of CIN II, and 28 cases of CIN III), and invasive squamous cell carcinoma (n = 21).

RESULTSIn exfoliated cell samples, telomerase activity was detected in 5 of 20 (25.0%) cases of cervicitis, 10 of 16 (62.5%) cases of CIN I, 11 of 20 (55.0%) cases of CIN II, 23 of 28 (82.1%) cases of CIN III, and 13 of 21 (61.9%) cases of carcinoma. In cervical biopsy samples, telomerase activity was detected in 6 of 20 (30.0%) cases of cervicitis, 8 of 16 (50.0%) cases of CIN I, 9 of 20 (45.0%) cases of CIN II, 27 of 28 (96.4%) cases of CIN III, and 20 of 21 (95.2%) cases of carcinoma. Telomerase activation was significantly higher in CIN samples than in cervicitis samples. Telomerase activity was detected at similar frequency in samples from cervical scrapings and cervical biopsies.

CONCLUSIONThese results seem to suggest that telomerase expression may be associated with carcinogenesis of the cervix. TRAP assay of cervical scraping samples could be used to monitor and predict the development of CIN in clinical practice.

AIMTo explore the effect of Triptolide on airway remodeling and the expression of Phosphoinositide 3-Kinases in asthmatic rats.

METHODS40 rats were randomly divided into 5 groups (n = 8): (1) Control group; (2) Asthmatic 4 weeks group; (3) Asthmatic 6 weeks group; (4) Therapeutic 4 weeks group; (5) Therapeutic 6 weeks group. The airway resistance and eosinophilic inflammation of airway wall were observed. The airway wall thickness (WA/Pi), the bronchial smooth muscle thickness (smooth muscle area/Pi) and the number of bronchial smooth muscle nucleus (N/Pi) were measured by image analysis system. The expression of PI3K protein and mRNA were determined by immunohistochemical staining and reverse transcription-polymerase chain reaction (RT-PCR).

RESULTS(1) The expression of PI3K p85alpha protein and mRNA in asthmatic 4 weeks group and asthmatic 6 weeks group were significantly higher than control group, respectively (P < 0.01). The above-mentioned parameters of therapeutic 6 weeks group were significantly lower than those of asthmatic 4 weeks group, asthmatic 6 weeks group and therapeutic 4 weeks group, respectively (P < 0.01, P < 0.01 P < 0.05). (2) The WA/Pi, the smooth muscle area/Pi and the N/Pi of asthmatic 4 weeks group and asthmatic 6 weeks group were significantly higher than control group, respectively (P < 0.01). The above-mentioned parameters of therapeutic 6 weeks group were significantly lower than those of asthmatic 4 weeks group, asthmatic 6 weeks group and therapeutic 4 weeks group, respectively (P < 0.01). (3) The airway resistance of asthmatic 4 weeks group and asthmatic 6 weeks group were significantly higher than the control group, respectively (P < 0.01). The above-mentioned parameters of therapeutic 6 weeks group were significantly lower than those of asthmatic 4 weeks group, asthmatic 6 weeks group and therapeutic 4 weeks group, respectively (P < 0.01, P < 0.01, P < 0.05).

CONCLUSIONThe proliferation of airway smooth muscle is a remarkable character of airway remodeling in asthma. The PI3K signal pathway may be involved in the process. Triptolide may reduce AHR and decrease the proliferation of ASMCs by inhibiting the expression of PI3K. It may have potential therapeutic effects in the asthmatic airway remodeling.

OBJECTIVETo explore the clinical and pathological features and the diagnosis of childhood Alport syndrome (AS).

METHODSA retrospective analysis was performed on clinical data of 91 children with AS.

RESULTSHematuria was observed in all 91 patients, of whom 86 were accompanied with proteinuria. Sixty-one children with X-Linked AS (XL-AS) had positive family history. Renal biopsy was performed on 82 children. Mild to moderate mesangial proliferation was observed in 74 cases. Small amounts of immune complexes deposits in the glomerular mesangial area were observed in 48 cases. Glomerular basement membrane (GBM) attenuation, thickening and layering were observed in 53 cases by electron microscopy (EM). In 63 cases receiving renal tissue type IV collagen α3 and α5 chain immunofluorescence detection, 58 were diagnosed with AS, including 53 cases of XL-AS and 5 cases of autosomal recessive AS. In 91 cases of AS, 58 were diagnosed as AS by renal tissue type IV collagen α3 and α5 chain immunofluorescence, 21 were diagnosed by EM, one was diagnosed by skin biopsy, and 12 were diagnosed by gene detection. Six novel mutations of COL4A5 gene were found. Forty-five cases were misdiagnosed before the diagnosis of AS. Forty-one of the 45 cases received steroids and/or immunosuppressant therapy.

CONCLUSIONSThe clinical manifestations and pathological changes are not specific in children with AS, resulting in a higher rate of misdiagnosis. Typical lesions of GBM under EM are only observed in a part of patients. There is a high novel mutation rate of COL4A5 in the detected AS children.
