ABSTRACT

Objective:To investigate the clinical efficacy of Huoxue Quban Decoction combined with Xiyu chloasma patch in the treatment of chloasma.Methods:Randomized controlled trial. A total of 126 chloasma patients were selected and divided into two groups according to the random number table method, 63 in each group. The control group were treated with Xiyu chloasma patch, and the observation group received Huoxue Quban Decoction combined with Xiyu chloasma patch. Both groups were treated continuously for 12 weeks. TCM syndrome scores were performed before and after treatment, and the severity of skin lesions was evaluated by the Melasma Area and Severity Index (MASI). Quality of life was evaluated by the Melasma Quality of Life (MELASQOL) scale. Serum SOD levels were measured by enzyme rate method, MDA levels were measured by micro method, and GSH-Px levels were measured by colorimetric method. Adverse reactions during treatment were recorded and clinical efficacy was evaluatedResults:The total effective rate of the observation group was 90.48% (57/63), while the control group was 71.43% (45/63). The difference between the two groups was statistically significant ( χ2=7.41, P=0.006). After treatment, the scores of traditional Chinese medicine syndrome scores ( Z=8.13), MASI ( Z=8.92), and MELASQOL ( t=11.52) in the observation group were significantly lower than those in the control group ( P<0.01). After treatment, the serum SOD [(203.07±25.24) g/L vs. (176.24±33.98) g/L, t=5.03] and GSH-Px [(8.28±1.27) U/L vs. (7.33±1.28) U/L, t=4.18] levels in the observation group were significantly higher than those in the control group ( P<0.01); MDA[(3.36±1.17) μmol/L vs. (5.20 ± 1.23) μmol/L, t=8.62] was significantly lower than that of the control group ( P<0.01). No significant adverse reactions occurred during the treatment period in both groups. Conclusion:The Huoxue Quban Decoction combined with Xiyu chloasma patch can improve the color, area and quality of life of chloasma lesions and reduce oxidative stress with high safety.

ABSTRACT

Objective:To explore the diagnostic value of CT pulmonary vascular quantitative parameters in patients with chronic obstructive pulmonary disease (COPD) and high-risk groups.Methods:A retrospective study of 1 126 patients who underwent chest CT examination and pulmonary function test in Shanghai Tongji Hospital from January 2015 to August 2020. According to lung function, they were divided into COPD group (471 cases), high-risk group (454 cases), and normal control group (201 cases). Pulmonary vascular parameters on chest CT, including the total number of vessels (N total), the number cross-sectional area of vessels under 5 mm 2 (N CSA<5), lung surface area (LSA), number of pulmonary blood vessels per unit lung surface area (N total/LSA) and the total area of vessels (VA total) at a 9, 15, 21 mm depth from the pleural surface, and the total blood vessel volume (TBV), blood vessel volume under 5 mm 2 and 10 mm 2(BV5 and BV10) were measured quantitatively. Kruskal-Wallis H test was used to compare the differences of quantitative parameters of pulmonary vascular in the three groups; Spearman rank test was used to analyze the correlation between CT pulmonary vascular parameters and pulmonary function. Results:There were significant differences in N total/LSA at a 9, 15, 21 mm depth from the pleural surface among three groups ( P<0.05). There were significant differences in N CSA<5, N total at a 9 mm depth from the pleural surface among three groups ( P<0.05). There were significant differences in LSA at a 9 mm depth from the pleural surface, N CSA<5, N total, LSA, VA total at a 15, 21 mm depth from the pleural surface and TBV, BV5 and BV10 among three groups ( P<0.05). In high-risk group, there were positive correlation between N total/LSA, VA total at a 9 mm depth from the pleural surface and some pulmonary function parameters ( r=0.095-0.139, P<0.05). N CSA<5, N total, LSA, N total/LSA, TBV, BV5 and BV10 at different depth from pleural surface were negatively correlated with some pulmonary function parameters ( r=-0.110--0.215, P<0.05). In COPD group, number of vessels at a 9 mm depth from the pleural surface was positively correlated with the diffusion capacity for carbon monoxide of the lung single breath ( r=0.105, 0.103, P<0.05). In addition to N total/LSA were positively correlated with lung function parameters ( r=0.181-0.324, P<0.05), the remaining pulmonary vascular parameters were negatively correlated with some pulmonary function parameters ( r=-0.092--0.431, P<0.05). Conclusion:Quantitative chest CT imaging are able to effectively evaluate pulmonary vascular changes in COPD patients and high-risk groups, and the quantitative parameters of pulmonary vascular CT may distinguish COPD from high-risk groups, providing a novel means for early diagnosis of COPD and prediction of high-risk groups.

ABSTRACT

Crohn disease is prone to complications such as intestinal fibrosis, stenosis, and even intestinal obstruction, with limited treatment options and unsatisfactory results. Its pathogenesis involves genetic, immune, environmental, and gut microbiota aspects. Exploring early predictive factors for intestinal fibrosis stenosis in Crohn disease plays an important role in early disease prediction, disease assessment, treatment evaluation, and recurrence monitoring. This article provides a series of reviews on the current biomarkers of Crohn disease-related intestinal fibrosis.

ABSTRACT

Objective:To investigate the efficacy and safety of radiotherapy for all metastases in patients with metachronous oligo-metastatic prostate cancer after radical treatment.Methods:From October 2011 to February 2021, 41 patients with prostate cancer with less than 5 metastases after radical treatment were retrospectively analyzed in a single center. The median age at radiotherapy was 68 (57-81) years. Forty patients (98%) received androgen deprivation therapy (ADT). There were 28 patients in the hormone sensitive (HSPC) group and 13 patients in the hormone resistant (CRPC) group. The median initial PSA was 24.4 (7.4-399.0) ng/ml. Tumor stage: T 2 stage 11 patients, T 3 stage 27 patients, T 4 stage 3 patients.30 patients were in N 0 stage and 11 patients in N 1 stage. Gleason score was 7 in 12 patients, 8 in 9 patients, 9 in 18 patients, and 10 in 2 patients.33 patients were treated with surgery, and 8 patients were treated with radiotherapy. The time span from diagnosis to metastasis was 3.1 (0.2-1.8) years. Conventional imaging examination (CT/ MRI/bone scan) before radiotherapy was used in 7 patients, and PSMA PET/CT examination was used in 34 patients.The median PSA before radiotherapy was 1.3(0.1-33.8) ng/ml. There were 62 metastases in 41 patients, including 1 lesion in 28 patients, 2 lesions in 9 patients, 3 lesions in 2 patients, and 5 lesions in 2 patients. Fifty-four patients had bone metastases and eight had retroperitoneal lymph node metastases. Twenty-two bone metastases were located in the pelvis, 18 in the vertebral body, 12 in the ribs, one in the femur and one in the sternum.The median metastatic volume was 5.8(0.2-81.7) cm 3.Daily image-guided rotational intensity modulated radiotherapy was used to cover all metastases.Dose segmentation modes include 37.5Gy/7.5Gy/5F, 60Gy/3Gy/20F, 65-70Gy/2.6-2.8Gy/25F.The median biological effective dose (BED 3) was 120 (67-147) Gy. The primary endpoint was biochemical progression-free survival (BPFS), the secondary endpoints were acute and late toxic side effects, local relapse-free survival (LPFS), and overall survival (OS). Results:The median follow-up time was 21 months (range 5-72 months). All patients completed radiotherapy, and 16 patients had grade 1 to 2 acute toxicity and side effects, and no grade 3 or above acute and late stage side effects. 1-year LPFS was 97.1%.The 1-year and 2-year BPFS were 77.5% and 59.2%, respectively. The median BPFS time was 29 months (range 13.9-44.2 months). Univariate analysis showed that the HSPC group ( P<0.001) and the group with total metastatic volume ≤ 5.8cm 3 ( P=0.010) had higher BPFS. The median BPFS time was 37 months in the retroperitoneal lymph node metastases subgroup and 17 months in the bone metastases subgroup ( P=0.141). In the HSPC group, the median BPFS was 30(22-38) months. After radiotherapy, PSA decreased in all 28 patients, and increased in 6 patients. The median BPFS was 12(4-18) months. In the CRPC group, the median BPFS was 4(0-8) months. PSA decreased in 10 patients (76.9%) after radiotherapy, and PSA decreased in 6 patients. The median BPFS was 5(3-28) months. Three patients’PSA did not decrease after radiotherapy, and they were treated with new endocrine therapy drugs, chemotherapy, immunotherapy and other systemic therapy. Conclusions:For patients with metachronous metastases after radical treatment, full coverage radiotherapy has good safety and high local control rate. HSPC patients and patients with low tumor load could be recommended to receive radiotherapy for all metastatic lesions preferentially, and patients with only retroperitoneal lymph node metastases may have better prognosis after radiotherapy than patients with bone metastases.

ABSTRACT

Cullin-RING E3 ubiquitin ligase (CRL)-4 is a member of the large CRL family in eukaryotes. It plays important roles in a wide range of cellular processes, organismal development, and physiological and pathological conditions. DDB1- and CUL4-associated factor 8 (DCAF8) is a WD40 repeat-containing protein, which serves as a substrate receptor for CRL4. The physiological role of DCAF8 is unknown. In this study, we constructed Dcaf8 knockout mice. Homozygous mice were viable with no noticeable abnormalities. However, the fertility of Dcaf8-deficient male mice was markedly impaired, consistent with the high expression of DCAF8 in adult mouse testis. Sperm movement characteristics, including progressive motility, path velocity, progressive velocity, and track speed, were significantly lower in Dcaf8 knockout mice than in wild-type (WT) mice. However, the total motility was similar between WT and Dcaf8 knockout sperm. More than 40% of spermatids in Dcaf8 knockout mice showed pronounced morphological abnormalities with typical bent head malformation. The acrosome and nucleus of Dcaf8 knockout sperm looked similar to those of WT sperm. In vitro tests showed that the fertilization rate of Dcaf8 knockout mice was significantly reduced. The results demonstrated that DCAF8 plays a critical role in spermatogenesis, and DCAF8 is a key component of CRL4 function in the reproductive system.

ABSTRACT

Objective:To investigate the effects of cancer susceptibility candidate gene 19 (CASC19) regulating the expression of microRNA-449b-5p (miR-449b-5p) on the proliferation, apoptosis and radiation sensitivity of cervical cancer cells.Methods:(1) HeLa cells of cervical cancer cell line were cultured. HeLa cells were irradiated with X-ray at different doses (0, 2, 4, 6, 8 Gy, respectively), then the expression level of CASC19 mRNA and miR-449b-5p were detected by real-time quantitative PCR. (2) HeLa cell proliferation, apoptosis, radiation sensitivity (expressed as a survival fraction) and its related protein expression included cyclin D1, cleaved-caspase-3, and histone variant H2AX (γ-H2AX) were examined after different treatment including silencing CASC19 expression, over-expressing miR-449b-5p, down-regulating miR-449b-5p and silencing CASC19 expression. (3) The dual luciferase reporter gene experiment and real-time quantitative PCR technology were used to verify the targeting relationship between CASC19 and miR-449b-5p.Results:(1) With the increase of X-ray irradiation different dose (0, 2, 4, 6, 8 Gy), the expression level of CASC19 mRNA in HeLa cells gradually increased ( F=502.681, P=0.000), and the expression level of miR-449b-5p gradually decreased ( F=202.936, P=0.000).(2) After silencing CASC19 expression or over-expressing miR-449b-5p, the survival rate of HeLa cells was significantly reduced ( P<0.05), the apoptosis rate was significantly increased ( P<0.05), the survival fraction was significantly reduced ( P<0.05), the expression level of cyclin D1 protein was significantly reduced ( P<0.05), and the expression levels of cleaved-caspase-3 and γ-H2AX protein were significantly increased ( P<0.05). After down-regulating miR-449b-5p and silencing CASC19 expression, the survival rate of HeLa cells was significantly reduced ( P<0.05), the apoptosis rate was significantly increased ( P<0.05), the survival fraction was significantly reduced ( P<0.05), the expression levels of cyclin D1 and γ-H2AX protein were significantly increased ( P<0.05), and the expression level of cleaved-caspase-3 was significantly decreased ( P<0.05). (3) Over expression of miR-449b-5p could significantly reduce the luciferase activity of CASC19 wild type (1.00±0.09 versus 0.37±0.05, P<0.01), but there were no significant effect on the luciferase activity of CASC19 mutant type (0.92±0.07 versus 0.94±0.05, P>0.05). After the expression of CASC19 was silenced, the expression level of miR-449b-5p in HeLa cells increased significantly (1.00±0.12 versus 4.84±0.49, P<0.05). After overexpression of CASC19, the expression level of miR-449b-5p in HeLa cells was significantly reduced (1.00±0.09 versus 0.38±0.04, P<0.05). Conclusion:CASC19 in HeLa cells negatively regulates the expression of miR-449b-5p, and down-regulating the expression of miR-449b-5p could partially reverse the effects of silencing CASC19 on HeLa cell proliferation, apoptosis and radiation sensitivity.

ABSTRACT

Objective To analyze the 10-year survival outcome and failure patterns for patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT),aiming to provide reference for optimized treatment for NPC.Methods Clinical data of 866 patients with NPC receiving IMRT from January 2001 to December 2008 were retrospectively analyzed.Survival analysis was performed using the Kaplan-Meier estimator.Univariate analysis was carried out by log-rank test and multivariate analysis was performed using Cox proportional hazards model.Results The median follow-up time was 132 months.The 10-year local recurrence-free survival (LRFS),distant metastasis-free survival (DMFS),progression-free survival (PFS) and disease specific survival (DSS) were 92.0%,83.4%,75.7% and 78.6%,respectively.A total of 210 patients died including 124 patients (59.0%) from distant metastasis,which was the primary cause of death,and 47 (22.3%) from local regional recurrence.Independent negative factors of DSS included age>50 years (P=0.00),LDH ≥ 245 IU/L (P=0.00),Hb< 120 g/L (P=0.01),T2-T4 staging (P=0.00),N1-N3 staging (P=0.00) and GTV-nx>20 cm3(P=0.00).The 10-year LRFS,DMFS and DSS of stage Ⅱ NPC patients did not significantly differ after IMRT alone and chemoradiotherapy (P=0.83,0.22,0.23).For patients with stage Ⅲ NPC,the 10-year LRFS and DSS in the chemoradiotherapy arm were significantly higher than those in the IMRT alone (P=0.01,0.01),whereas no statistical significance was observed in the DMFS between two groups (P=0.14).The overall survival of stage Ⅳa+Ⅳb NPC patients is relatively poor.Conclusions IMRT can improve the long-term survival of NPC patients.Distant metastasis is the primary failure pattern.Patients with stage Ⅰ-Ⅱ NPC can obtain satisfactory survival outcomes after IMRT alone.The addition of chemotherapy can further enhance the LRFS and DSS of stage Ⅲ NPC patients.However,the optimal therapeutic strategy remains to be urgently investigated for stage a+ Ⅳb NPC patients.

ABSTRACT

A thin layer chromatograph-fluorescent method was used to assay content of scopoletin in Erycibe obtusi folia Benth.. The method showed that it not only can minimize analytical errors in thin layer scan and column contamination in HPLC,but also eliminated mutual interference of components in the preparation. It provides a good assay technique for quality control of hebal preparations. The method was carried out on thin layer plates of silica gel H(40?)with benzene-ether (1. 1: 1 )as the developer,at an excitation spectrum of 347nm,fluorescence spectrum of 420nm and a temperture of 25??1℃.The method showed good linearity(r= 0. 9998, n = 5)in the range of 0.08~0. 40?g/?l of scopoletin and the average recovery was 98. 52 % ~ 102. 67 % with RSD

ABSTRACT

Uracil (I) (2,4-Diketo-pyrimidine) was isolated from the radix aconiti collected from Jiangyou region of Sichuan Province.The chemical structure of this principle was determined by elemental analysis,IR,UV,MS,'H and 13C-NMR spectral data. The experiments were made to study the effect of uracil (I) on the cardiac contractile force and beating rate of the isolated toad hearts in comparison with uracil (II) (artificial synthesis). The results indicated that the 5?mol/L of uracil (I) and uracil (II) both had the effect of increasing the amplitude of myocardial contraction (P0.05) at 3 and 5 min. When the concentration was increased to 10 and 20?mol/L, the amplitudes of myocardial contraction were more incremental and 3 min later,the estimated value of uracil (I) and uracil (II) to increase the amplitude of myocardial contraction by 50% approached to 4.17 and 4.68, respectively. As described above, uracil (I) is a new cardiotonic in Jiangyou Fuzi.
