ABSTRACT

Elemene, derived from Curcuma wenyujin, one of the "8 famous genuine medicinal materials of Zhejiang province," exhibits remarkable antitumor activity. It has gained wide recognition in clinical practice for effectiveness on tumors. Dr. XIE Tian, introduced the innovative concept of "molecular compatibility theory" by combining Chinese medicine principles, specifically the "monarch, minister, assistant, and envoy" theory, with modern biomedical technology. This groundbreaking approach, along with a systematic analysis of Chinese medicine and modern biomedical knowledge, led to the development of elemene nanoliposome formulations. These novel formulations offer numerous advantages, including low toxicity, well-defined composition, synergistic effects on multiple targets, and excellent biocompatibility. Following the principles of the "molecular compatibility theory", further exploration of cancer treatment strategies and methods based on elemene was undertaken. This comprehensive review consolidates the current understanding of elemene's potential antitumor mechanisms, recent clinical investigations, advancements in drug delivery systems, and structural modifications. The ultimate goal of this review is to establish a solid theoretical foundation for researchers, empowering them to develop more effective antitumor drugs based on the principles of "molecular compatibility theory".

ABSTRACT

OBJECTIVE To provide feasible regulatory paths for the online sales supervision of Chinese medicinal materials from the perspective of the characteristics of new online sales and the characteristics of Chinese medicinal materials. METHODS Through the investigation of the sales form of Chinese medicinal materials on the e-commerce platform and the search of Chinese medicinal materials online dispute cases, the difficulties and existing problems in the supervision of Chinese medicinal materials under the new online sales model were analyzed, and corresponding countermeasures were proposed. RESULTS & CONCLUSIONS Clarifying the conceptual boundary between Chinese medicinal materials and their decoction pieces, agricultural products and food is the key to standardizing the online sale of Chinese medicinal materials. The regulatory criteria, which determine whether Chinese medicinal materials belong to drug management based on whether they had been included in medicinal channels, didn’t consider the diversity of online sales channels for Chinese medicinal materials, their safety and the disguised sales of Chinese herbal decoction pieces. It is necessary to establish the concept of hierarchical management of Chinese medicinal materials, strictly restrict the behavior of claiming the efficacy of Chinese medicinal materials and selling Chinese herbal decoction pieces in live streaming, improve the defining path of false propaganda of Chinese medicinal materials, implement the responsibilities and obligations of live streaming marketing subjects and platforms, and safeguard the legitimate rights of consumers.

ABSTRACT

Cryptococcus gattii is a kind of Cryptococcus that infects the lungs and central nervous system through the inhalation of infectious particles such as spores or Cryptococcus yeast cells. The development of clinical disease of Cryptococcus gattii may be determined by the sex, immunity and genetics of the host factors, in which immune system factors play an important role in host injury. Their defects will have serious clinical consequences. Cryptococcus gattii mainly infects the population with normal immune, and the infection of immunosuppressed population is rare. The infection mechanism, molecular types, clinical characteristics, treatment and prognosis of Cryptococcus gattii meningitis were different between the two populations. This article reviews the main differences in different immune status with Cryptococcus gattii meningitis.

ABSTRACT

Objective:To explore the efficacy and safety of blinatumomab in treatment of relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL).Methods:The data of 8 patients with relapsed/refractory B-ALL treated with blinatumomab in Shanghai Zhaxin Traditional Chinese and Western Medicine Hospital from September 2020 to December 2021 were retrospectively analyzed, and their clinical characteristics, overall survival, lymphocyte subsets, cytokines, tandem transplantation and adverse reactions were analyzed.Results:The median follow-up time of 8 patients was 143 d (range: 41-534 d). Five of the 8 patients were alive; among them, 4 of 6 patients assessed to be in minimal residual disease (MRD)-negative complete remission (CR) and 1 of 2 patients assessed to be in non-remission at the time of belintuzumab discontinuation were alive. The median duration of treatment with belintuzumab was 28 d (10-56 d), and it was 23 d (10-56 d) for patients with MRD-positive at baseline and 28 d (25-31 d) for the 4 non-remission patients. Six patients achieved MRD-negative CR after treatment, of which 4 were assessed as MRD-positive at baseline and 2 were assessed as non-remission at baseline. All 4 patients with MRD-positive CR achieved MRD-negative CR after treatment with belintuzumab, including 1 patient with Philadelphia chromosome-positive (Ph +) ALL bridged to autologous hematopoietic stem cell transplantation, and 1 patient with Ph + ALL and 1 patient with Ph - ALL received sequential allogeneic hematopoietic stem cell transplantation and had persistent MRD-negative CR. Two of the 4 non-remission patients achieved MRD-negative CR after treatment with belintuzumab, including 1 patient with Ph + ALL bridged to autologous hematopoietic stem cell transplantation, and 1 patient with Ph - ALL received sequential allogeneic hematopoietic stem cell transplantation, and the 2 patients had persistent MRD-negative CR. Leukocyte counts and neutrophils decreased in both MRD-positive CR and non-remission patients after receiving belintumomab. The proportion and absolute number of CD3 + T and CD3 + CD8 + T lymphocytes in patients with MRD-positive CR were higher than those in patients without remission, and both decreased after drug administration. Median interleukin-6 (46.23, 1.42 pg/ml), interleukin-8 (17.85, 2.10 pg/ml), interleukin-10 (7.43, 1.49 pg/ml) and interferon-γ (11.82, 0.39 pg/ml) levels were elevated in MRD-positive CR and non-remission patients at week 3 of treatment. Grade 1 cytokine release syndrome occurred in 1 case with clinical manifestations of fever, which improved after drug suspension. Three cases developed infections, 2 of which were pulmonary and 1 of which was upper respiratory tract infection. No immune effector cell-associated neurotoxic syndrome was observed. Conclusions:Belintumomab is effective for MRD clearance in relapsed/refractory B-ALL with manageable adverse reactions, providing an effective therapeutic option for bridging hematopoietic stem cell transplantation to prolong the survival of patients.

ABSTRACT

OBJECTIVES@#To study the protective effect of melatonin (Mel) against oxygen-induced retinopathy (OIR) in neonatal mice and the role of the HMGB1/NF-κB/NLRP3 axis.@*METHODS@#Neonatal C57BL/6J mice, aged 7 days, were randomly divided into a control group, a model group (OIR group), and a Mel treatment group (OIR+Mel group), with 9 mice in each group. The hyperoxia induction method was used to establish a model of OIR. Hematoxylin and eosin staining and retinal flat-mount preparation were used to observe retinal structure and neovascularization. Immunofluorescent staining was used to measure the expression of proteins and inflammatory factors associated with the HMGB1/NF-κB/NLRP3 axis and lymphocyte antigen 6G. Colorimetry was used to measure the activity of myeloperoxidase.@*RESULTS@#The OIR group had destruction of retinal structure with a large perfusion-free area and neovascularization, while the OIR+Mel group had improvement in destruction of retinal structure with reductions in neovascularization and perfusion-free area. Compared with the control group, the OIR group had significant increases in the expression of proteins and inflammatory factors associated with the HMGB1/NF-κB/NLRP3 axis, the expression of lymphocyte antigen 6G, and the activity of myeloperoxidase (P<0.05). Compared with the OIR group, the OIR+Mel group had significant reductions in the above indices (P<0.05). Compared with the control group, the OIR group had significant reductions in the expression of melatonin receptors in the retina (P<0.05). Compared with the OIR group, the OIR+Mel group had significant increases in the expression of melatonin receptors (P<0.05).@*CONCLUSIONS@#Mel can alleviate OIR-induced retinal damage in neonatal mice by inhibiting the HMGB1/NF-κB/NLRP3 axis and may exert an effect through the melatonin receptor pathway.

ABSTRACT

OBJECTIVES@#To summarize the clinical features of neonates infected with Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).@*METHODS@#The medical data of 23 neonates with Omicron variant of SARS-CoV-2 infection admitted to the City North Campus of Urumqi First People's Hospital from October to December 2022 were retrospectively reviewed.@*RESULTS@#All 23 infants had a history of exposure to confirmed caregivers with SARS-CoV-2 infection after birth, and none of them was vertically transmitted. Clinical classification: 5 cases of asymptomatic infection, 18 cases of mild infection, and no cases of moderate, severe, or critically ill. The first symptoms were fever in 13 cases, cough in 3 cases, nasal congestion in 1 case, and diarrhea in 1 case. Blood white blood cell counts decreased in 2 cases, and C-reactive protein increased in 1 case. Seven infants underwent chest X-ray examination due to cough or shortness of breath, and one of which showed focal exudative changes, while the rest showed no abnormal changes. All infants were discharged after symptomatic treatment and the median hospital stay was 6 days. The duration of nucleic acid positivity of SARS-CoV-2 was negatively correlated with N gene Ct values and ORF1ab gene Ct values (rs=-0.719 and -0.699, respectively; P<0.05). One month after discharge, all infants had no symptoms or signs of nucleic acid re-positivity.@*CONCLUSIONS@#The clinical manifestations are usually mild or asymptomatic in neonates infected with SARS-CoV-2 Omicron variant. The lower the Ct values of the N and ORF1ab genes of SARS-CoV-2, the longer the duration of nucleic acid positivity. Neonates infected with SARS-CoV-2 Omicron variant can have a good prognosis after symptomatic treatment.

ABSTRACT

The development of anticancer drugs targeting AKT1 has been reported in a variety of cancers, but there are few related studies on Chinese medicinals targeting AKT1- In this study, Compound stomachache capsules (CSC) was used for inhibiting prostate cancer (PC) cells growth by targeting AKT1 in vitro and in vivo. Through mass spectrum, target prediction and bioinformatics analysis, it is found that 37 of CSC compounds have anticancer activity, and 6 compounds such as (+)-Magnoflorine, 7-hydroxycoumarin may be their main active components against prostate cancer- The results showed that CSC had significant in vitro inhibition on the growth of prostate cancer cells (P<0- 01), and the growth inhibition rate of PC3 cells reached about 35% at 80 μg/ mL- CSC also increased ROS production, and significantly promoted apoptosis (P <0- 01) and G

ABSTRACT

Objective: To explore the efficacy of immunosuppression intensified conditioning regimen in patients who have strongly positive donor-specific Anti-HLA antibodies (DSAs) and received a haploidentical hematopoietic stem cell transplantation (haplo-HSCT) . Methods: Clinical data of 10 patients with strongly positive pretransplant DSAs (defined as MFI ≥10000) were retrospectively analyzed in this study. All of them received a haplo-HSCT in the Hematology Department of Shanghai Zhaxin Traditional Chinese & Western Medicine Hospital. Results: ① Of all ten patients, three were males, and seven were females, with a median age of 53.5 (36-64) years. Of the 10 patients, three were diagnosed with acute myeloid leukemia, two were myelodysplastic syndromes (MDS), two were chronic myelomonocytic leukemia (CMML), two were in an accelerated phase of chronic myeloid leukemia (CML-AP), and one was primary myelofibrosis (PMF). ② Conditioning regimen consisted of fludarabine (Flu) /busulfan (Bu) combined with whole-body irradiation (TBI) /cyclophosphamide (Cy). ③ On the seventh day after transplantation, the median pretransplant DSA level was MFI 15 999 (10 210-23 417) and 10 787 (0-22 720). ④ Eight patients acquired hematopoietic reconstitution; the median time of neutrophil engraftment was 14 (10-16) days; and 18 (14-20) days for platelet engraftment. After a median follow-up of 12.5 (1.5-27) months, primary graft failure was found in one patient and another with poor graft function. Seven patients remained in a disease remission state, and all were DSA-negative. Conclusions: An intensified immunosuppression conditioning regimen can efficiently decrease the level of donor-specific anti-HLA antibodies (DSAs), leading to good short-term efficacy.

ABSTRACT

Objective To explore the residual level of FPMs in indoor dust samples in Shenzhen from 2020 and 2021, and to analyze its temporal distribution characteristics. Methods In the present study, indoor dust samples (n=193) from residential buildings in Shenzhen. were collected to analyze the temporal variation characteristics of FPMs. Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was applied to determine the concentrations of FP and its four major metabolites (fipronil-sulfone, fipronil-sulfide, fipronil-desulfinyl, and fipronil-amide; abbreviated as FP-SFO, FP-SFI, FP-DES, and FP-AM) in the samples. The sum of the concentrations of FP and its four metabolites was represented as additive mass concentration (ΣFPMs). Additionaly, Wilcoxon test was performed to determine the temporal distribution differences of FPMs’ concentrations. Results From 2020 to 2021, the concentration of ΣFPMs for the in door dust samples in Shenzhen ranged from 0.51 to 4 415 ng/g (median: 18.8ng/g). FP, FP-SFO AND FP-SFI were the major target analytes in the sample with detection rates of 90.60%,86.20% and 75.40%, respectively. The detection rates of other metabolites were low (≤ 44.3%). Analysis of the temporal variation trend of FPMs’ concentrations showed that there was no significant difference in the levels of ΣFPMs between warm season(spring and summer)and cold season(autumn and winter)in the indoor dust samples from 2020 to 2021(2.38 vs 2.84ng/g , P > 0.05). However , the concentrations of FP-SFI and ΣFPMs in the indoor dust samples collected from 2021 showed an significantly increasing trend compared with 2020(1.02 vs 1.89 , 17.80vs. 20.10 ng/g , P < 0.05). Conclusion From 2020 to 2021 , the detection level of FPMs in indoor dust in Shenzhen is relatively high and shows an upward trend , with no obvious seasonal difference. However, whether the residual level of FPMs in indoor dust poses a risk to human health needs further study.

ABSTRACT

Objective: In this study, we aimed to investigate the prevalence of low anterior resection syndrome (LARS) in patients who had survived for more than 5 years after sphincter-preserving surgery for rectal cancer and to analyze its relationship with postoperative time. Methods: This was a single-center, retrospective, cross-sectional study. The study cohort comprised patients who had survived for at least 5 years (60 months) after undergoing sphincter- preserving radical resection of pathologically diagnosed rectal adenocarcinoma within 15 cm of the anal verge in the Department of Gastrointestinal Surgery, Peking University People's Hospital from January 2005 to May 2016. Patients who had undergone local resection, had permanent stomas, recurrent intestinal infection, local recurrence, history of previous anorectal surgery, or long- term preoperative defecation disorders were excluded. A LARS questionnaire was administered by telephone interview, points being allocated for incontinence for flatus (0-7 points), incontinence for liquid stools (0-3 points), frequency of bowel movements (0-5 points), clustering of stools (0-11 points), and urgency (0-16 points). The patients were allocated to three groups based on these scores: no LARS (0-20 points), minor LARS (21-29 points), and major LARS (30-42 points). The prevalence of LARS and major LARS in patients who had survived more than 5 years after surgery, correlation between postoperative time and LARS score, and whether postoperative time was a risk factor for major LARS and LARS symptoms were analyzed. Results: The median follow-up time of the 160 patients who completed the telephone interview was 97 (60-193) months; 81 (50.6%) of them had LARS, comprising 34 (21.3%) with minor LARS and 47 (29.4%) with major LARS. Spearman correlation analysis showed no significant correlation between LARS score and postoperative time (correlation coefficient α=-0.016, P=0.832). Multivariate analysis identified anastomotic height (RR=0.850, P=0.022) and radiotherapy (RR=5.760, P<0.001) as independent risk factors for major LARS; whereas the postoperative time was not a significant risk factor (RR=1.003, P=0.598). The postoperative time was also not associated with LARS score rank and frequency of bowel movements, clustering, or urgency (P>0.05). However, the rates of incontinence for flatus (3/31, P=0.003) and incontinence for liquid stools (8/31, P=0.005) were lower in patients who had survived more than 10 years after surgery. Conclusions: Patients with rectal cancer who have survived more than 5 years after sphincter-preserving surgery still have a high prevalence of LARS. We found no evidence of major LARS symptoms resolving over time.

ABSTRACT

Objective: To propose a new staging system for presacral recurrence of rectal cancer and explore the factors influencing radical resection of such recurrences based on this staging system. Methods: In this retrospective observational study, clinical data of 51 patients with presacral recurrence of rectal cancer who had undergone surgical treatment in the Department of Gastrointestinal Surgery, Peking University People's Hospital between January 2008 and September 2022 were collected. Inclusion criteria were as follows: (1) primary rectal cancer without distant metastasis that had been radically resected; (2) pre-sacral recurrence of rectal cancer confirmed by multi-disciplinary team assessment based on CT, MRI, positron emission tomography, physical examination, surgical exploration, and pathological examination of biopsy tissue in some cases; and (3) complete inpatient, outpatient and follow-up data. The patients were allocated to radical resection and non-radical resection groups according to postoperative pathological findings. The study included: (1) classification of pre-sacral recurrence of rectal cancer according to its anatomical characteristics as follows: Type I: no involvement of the sacrum; Type II: involvement of the low sacrum, but no other sites; Type III: involvement of the high sacrum, but no other sites; and Type IV: involvement of the sacrum and other sites. (2) Assessment of postoperative presacral recurrence, overall survival from surgery to recurrence, and duration of disease-free survival. (3) Analysis of factors affecting radical resection of pre-sacral recurrence of rectal cancer. Non-normally distributed measures are expressed as median (range). The Mann-Whitney U test was used for comparison between groups. Results: The median follow-up was 25 (2-96) months with a 100% follow-up rate. The rate of metachronic distant metastasis was significantly lower in the radical resection than in the non-radical resection group (24.1% [7/29] vs. 54.5% [12/22], χ2=8.333, P=0.026). Postoperative disease-free survival was longer in the radical resection group (32.7 months [3.0-63.0] vs. 16.1 [1.0-41.0], Z=8.907, P=0.005). Overall survival was longer in the radical resection group (39.2 [3.0-66.0] months vs. 28.1 [1.0-52.0] months, Z=1.042, P=0.354). According to univariate analysis, age, sex, distance between the tumor and anal verge, primary tumor pT stage, and primary tumor grading were not associated with achieving R0 resection of presacral recurrences of rectal cancer (all P>0.05), whereas primary tumor pN stage, anatomic staging of presacral recurrence, and procedure for managing presacral recurrence were associated with rate of R0 resection (all P<0.05). According to multifactorial analysis, the pathological stage of the primary tumor pN1-2 (OR=3.506, 95% CI: 1.089-11.291, P=0.035), type of procedure (transabdominal resection: OR=29.250, 95% CI: 2.789 - 306.811, P=0.005; combined abdominal perineal resection: OR=26.000, 95% CI: 2.219-304.702, P=0.009), and anatomical stage of presacral recurrence (Type III: OR=16.000, 95% CI: 1.542 - 166.305, P = 0.020; type IV: OR= 36.667, 95% CI: 3.261 - 412.258, P = 0.004) were all independent risk factors for achieving radical resection of anterior sacral recurrence after rectal cancer surgery. Conclusion: Stage of presacral recurrences of rectal cancer is an independent predictor of achieving R0 resection. It is possible to predict whether radical resection can be achieved on the basis of the patient's medical history.

ABSTRACT

OBJECTIVE@#To investigate the mechanism of self-efficacy between self-management ability and self-management behavior and its differences among patients with different disease courses through mediation tests.@*METHODS@#In the study, 489 patients with type 2 diabetes who attended the endocrinology departments of four hospitals in Shanxi Province and Inner Mongolia Autonomous Region from July to September 2022 were enrolled as the study population. They were investigated by General Information Questionnaire, Diabetes Self-Management Scale, Chinese version of Diabetes Empowerment Simplified Scale, and Diabetes Self-Efficacy Scale. Mediation analyses were performed using the linear regression model, Sobel test, and Bootstrap test in the software Stata version 15.0 and divided the patients into different disease course groups for subgroup analysis according to whether the disease course was > 5 years.@*RESULTS@#In this study, the score of self-management behavior in the patients with type 2 diabetes was 6.16±1.41, the score of self-management ability was 3.99±0.74, and the score of self-efficacy was 7.05±1.90. The results of the study showed that self-efficacy was positively correlated with self-management ability (r=0.33) as well as self-management behavior (r=0.47) in the patients with type 2 diabetes (P < 0.01). The mediating effect of self-efficacy accounted for 38.28% of the total effect of self-management ability on self-management behaviors and was higher in the behaviors of blood glucose monitoring (43.45%) and diet control (52.63%). The mediating effect of self-efficacy accounted for approximately 40.99% of the total effect for the patients with disease course ≤ 5 years, while for the patients with disease course > 5 years, the mediating effect accounted for 39.20% of the total effect.@*CONCLUSION@#Self-efficacy enhanced the effect of self-management ability on the behavior of the patients with type 2 diabetes, and this positive effect was more significant for the patients with shorter disease course. Targeted health education should be carried out to enhance patients' self-efficacy and self-management ability according to their disease characteristics, to stimulate their inner action, to promote the development of their self-management behaviors, and to form a more stable and long-term mechanism for disease management.

The scores of the core knowledge of chronic disease prevention and control were described by median and interquartile range, the Wilcoxon rank sum test or the Kruskal Wallis test was used for the inter-group comparison, and the correlation factors of the total score were analyzed by the multilinear regression model. Results: A total of 172 808 participants were surveyed in 302 counties and districts, of which 42.60%(73 623) were male and 57.40%(99 185) were female; The proportion of respondents aged 18-44, 45-59, and 60 years old and above was 54.74% (94 594), 30.91% (53 423) and 14.35% (24 791), respectively. The total score of the core knowledge of chronic prevention and control in the total population was 66(13), and the scores of different characteristic groups were different, and the differences were statistically significant: the eastern region had the highest score at 67(11) (H=840.66, P<0.01), the urban 66(12) was higher than the rural 65(14) (Z=-31.35, P<0.01), and the male 66(14) was lower than female 66(12) (Z=-11.66, P<0.01), 18-24 years old 64(13) was lower than other age groups(H=115.80, P<0.01), and undergraduate degree and above had the highest score compared to other academic qualifications, with 68(9) points(H=2 547.25, P<0.01). Multivariate analysis showed that eastern (t=27.42, P<0.01), central (t=17.33, P<0.01), urban (t=5.69, P<0.01), female (t=17.81, P<0.01), high age (t=46.04, P<0.01) and high education (t=57.77, P<0.01) had higher scores of core knowledge of chronic disease prevention and control than other groups, the scores of core knowledge of chronic disease prevention and control of professional and technical personnel (t=8.63, P<0.01), state enterprises and institutions (t=38.67, P<0.01), agriculture, forestry, animal husbandry, fishery and water conservancy production (t=5.30, P<0.01), production, transportation and commercial personnel (t=24.87, P<0.01), and other workers (t=8.89, P<0.01) were higher than those of non-employed people. Conclusion: There are differences in the total scores of the core knowledge of chronic disease prevention and control in different characteristics of people in China, and in the future, health education on the prevention and treatment of chronic diseases should be strengthened for specific groups to improve the knowledge level of residents.

ABSTRACT

Objective To explore the protective mechanism of transdifferentiation of glomerular endothelial cells based on the differentiated embryonic chondrocyte gene 2 (DEC2) via the TGF-β/ROCK1 signaling pathway. Methods The 24 mice were randomly divided into sham group, UUO group, UUO combined with vector group and UUO combined with DEC2 group, with 6 mice in each group. A unilateral ureteral obstruction (UUO) model was established in each group, except for the sham group. In the UUO combined with vector group and UUO combined with DEC2 group, 10 μL (108 PFU) of vector or DEC2 was injected into each kidney on day 0 (immediately after UUO) under the guidance of the ultrasound system. The mice were sacrificed 14 days after the operation, and the kidneys were collected for histological examination and Western blot analysis: HE staining was used to observe the histological changes of kidneys, Masson staining to observe the renal fibrosis, and Western blot analysis to detect the protein expression. In vitro, normal human glomerular endothelial cells (GEnCs) was selected as the research objects. GEnCs stimulated with TGF-β were treated with ROCK1 inhibitor Y-27632 or DEC2 transfection. Western blot analysis was used to detect the expression of ROCK1, α-SMA, DEC2 and E-cadherin in GEnC exposed to transforming growth factor β (TGF-β). The localization of ROCK1 and DEC2 in GEnCs cells was detected by immunofluorescence cytochemistry. The relationship between the ROCK1 and DEC2 was confirmed by co-immunoprecipitation. Results Compared with the sham group, the UUO groups showed significant renal fibrosis and collagen accumulation on the 14th day. In the UUO groups, the expression of DEC2 and E-cadherin in the kidney tissue of the mice was significantly reduced, and the expression of α-SMA significantly increased. Compared with the UUO combined with vector group, the kidney fibrosis and collagen accumulation in the UUO combined with DEC2 group decreased, and the expression of ROCK1 and α-SMA decreased and the expression of DEC2 and E-cadherin increased in the kidney tissue. TGF-β enhanced the expression of ROCK1 and α-SMA in GEnCs cells in a time-dependent manner, and the levels of DEC2 and E-cadherin decreased. Treatment with the ROCK1 inhibitor Y-27632 partially abrogated the TGF-β-induced increase in the expression of ROCK1 and α-SMA and decrease in the expression of DEC2 and E-cadherin. In addition, transfection of GEnCs cells with DEC2 before TGF-β stimulation reduced the expression of ROCK1 and α-SMA, and increased the expression of DEC2 and E-cadherin. Immunofluorescence cytochemical staining showed that DEC2 co-localized with ROCK1 in GEnCs, and the co-immunoprecipitation showed that DEC2 and ROCK1 pulled down each other. Conclusions DEC2 is down-regulated in fibrotic renal tissue, while up-regulated DEC2 inhibits epithelial myofibroblast transdifferentiation and renal fibrosis of GEnC by blocking TGF-β/ROCK1 signaling pathway.

ABSTRACT

The growth environment of medicinal plants plays an important role in the formation of their medicinal quality. However, there is a lack of combined analysis studying the close relationship between the growth environment, chemical components, and related biological activities of medicinal plants. Therefore, this study investigated the effect of different soil moisture treatments on the efficacy to eliminate dampness and relieve jaundice and the flavonoid content of Sedum sarmentosum, and explored their correlation. The flavonoid content in the decoction of S. sarmentosum growing under field conditions with soil moisture levels of 35%-40%(T1), 55%-60%(T2), 75%-80%(T3), and 95%-100%(T4) was compared. The effects of these treatments on liver function parameters, liver inflammation, and oxidative damage in mice with dampness-heat jaundice were evaluated, and the correlation between pharmacological indicators and flavonoid content was analyzed. The results showed that the total flavonoid and total phenolic acid content in the decoction of S. sarmentosum were highest in the T1 treatment, followed by the T3 treatment. The content of quercetin, kaempferol, and isorhamnetin was highest in the T2, T1, and T3 treatments, respectively. Among the different moisture treatments, the T3 group of S. sarmentosum effectively reduced the levels of serum ALT, AKP, TBIL, DBIL, TBA, as well as hepatic TNF-α and IL-6 in mice with jaundice, followed by T2 treatment, especially in reducing AST level. The T4 treatment had the poorest effect. Correlation analysis showed a significant negative correlation between AST, ALT, AKP levels in mice and the total content of quercetin and the three flavonoids. MDA showed a significant negative correlation with the total flavonoid content and kaempferol. TNF-α exhibited a significant negative correlation with the content of isorhamnetin. In conclusion, S. sarmentosum growing under field conditions with a soil moisture level of 75%-80% exhibited the best efficacy to eliminate dampness and relieve jaundice. This study provides insights for optimizing the cultivation mode of medicinal plants guided by pharmacological experiments.

ABSTRACT

AIM: To investigate the mechanism of pyrrolidine dithiocarbamate(PDTC)on transforming growth factor-beta 2(TGF-β2)-induced epithelial-mesenchymal transition(EMT)in human lens epithelial cells(LECs).METHODS: LECs were treated with various doses of PDTC chemicals following TGF-β2 caused EMT on these cells. Cell proliferation and lateral migration were discovered using the CCK-8 and cell scratch test. The markers of EMT, including E-cadherin, α-SMA and nuclear factor-κB(NF-κB)signaling pathway-related expression, were tested by Western Blot as well as the changes in the expression of the apoptosis-related proteins BAX, BCL-2, Caspase-3, and Cyclin D1.RESULTS: The proliferation and migration viability of cells in the TGF-β2 treated group was increased compared to the group without TGF-β2, and the expression of α-SMA increased whereas the E-cadherin expression decreased. With the effect of TGF-β2, NF-κB p65 and phosphorylated NF-κB p65 expression increased, the concentration of TGF-β2 that had the greatest capacity for proliferation and migration was 10 ng/mL(P&#x003C;0.05). Mechanism study of PDTC-induced EMT reversal and apoptosis showed that cell viability and migratory capability were both significantly reduced after PDTC intervention; PDTC prevents IκB phosphorylation, thus inhibiting NF-κB nuclear translocation. Protein associated to the NF-κB signaling pathway, and protein expression of NF-κB/IκBα/p-IκBα/Iκκ-α/p-Iκκ-α was decreased(P&#x003C;0.05), PDTC increased the expression of the pro-apoptotic protein BAX/Caspase-3, expression of the inhibitor of apoptosis protein BCL-2 and the cell cycle protein Cyclin D1 was reduced. The expression of NF-κB/IκB mRNA was reduced, expression of the apoptosis-related mRNA BAX increased, while BCL-2 reduced.CONCLUSION: The EMT in LECs cells induced by TGF-β2 can be significantly reversed by PDTC, which may be related to the decreased expression of NF-κB p65/IκB/Iκκ-α and activation of apoptosis-related protein. PDTC can reverse EMT by inhibiting NF-κB signaling pathway and induce apoptosis of abnormally proliferated cells, which will provide new potential therapeutic agents for posterior capsular opacification(PCO)treatment.

ABSTRACT

BACKGROUND@#The benefits of healthy lifestyles are well recognized. However, the extent to which improving unhealthy lifestyles reduces cardiovascular disease (CVD) risk needs to be discussed. We evaluated the impact of lifestyle improvement on CVD incidence using data from the China-PAR project (Prediction for Atherosclerotic Cardiovascular Disease Risk in China).@*METHODS@#A total of 12,588 participants free of CVD were followed up for three visits after the baseline examination. Changes in four lifestyle factors (LFs) (smoking, diet, physical activity, and alcohol consumption) were assessed through questionnaires from the baseline to the first follow-up visit. Cox proportional hazard models were used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). The risk advancement periods (RAPs: the age difference between exposed and unexposed participants reaching the same incident CVD risk) and population-attributable risk percentage (PAR%) were also calculated.@*RESULTS@#A total of 909 incident CVD cases occurred over a median follow-up of 11.14 years. Compared with maintaining 0-1 healthy LFs, maintaining 3-4 healthy LFs was associated with a 40% risk reduction of incident CVD (HR = 0.60, 95% CI: 0.45-0.79) and delayed CVD risk by 6.31 years (RAP: -6.31 [-9.92, -2.70] years). The PAR% of maintaining 3-4 unhealthy LFs was 22.0% compared to maintaining 0-1 unhealthy LFs. Besides, compared with maintaining two healthy LFs, improving healthy LFs from 2 to 3-4 was associated with a 23% lower risk of CVD (HR = 0.77, 95% CI: 0.60-0.98).@*CONCLUSIONS@#Long-term sustenance of healthy lifestyles or improving unhealthy lifestyles can reduce and delay CVD risk.

ABSTRACT

OBJECTIVE@#To explore the genotypes and prenatal diagnosis of thalassemia in couples of childbearing age in Quanzhou, Fujian Province.@*METHODS@#Blood routine and hemoglobin electrophoresis were performed for initial thalassemia screening in 76 328 couples in Quanzhou region from July 2017 to July 2020. The couples with positive initial screening results further underwent thalassemia gene test. Couples carrying homotypic thalassemia genes underwent prenatal diagnosis in the second trimester.@*RESULTS@#Among 76 328 couples of childbearing age, 1 809 couples of positive initial thalassemia screening were identified, with the positive rate about 2.37%. Further results of genetic detection of the 1 809 couples showed that 985 cases were diagnosed as α- thalassemia, of which --sea/αα was the most frequency, followed by -α3.7/αα and ααQS/αα; 296 cases were diagnosed as β-thalassemia, the most frequency mutations were 654M/N and 41-42M/N; 26 cases of compound α and β-thalassemia were detected. In addition, 3 rare cases of thalassemia were detected, including --THAI/αα, SEA-HPFH, and -α6.9/--sea. Among them, 108 couples were confirmed as homologous thalassemia, with the detection rate about 5.97%, including 96 couples of homologous α-thalassemia, 9 couples of homologous β-thalassemia, and 3 couples with one had compound α- and β-thalassemia. Among them, 17 couples with homologous α-thalassemia underwent prenatal diagnosis in the second trimester, of which 1 case of Hb Bart's Hydrops Syndrome, 3 cases of HbH disease, 9 cases of silent thalassemia or α-thalassemia minor, and 4 cases of healthy fetuses were detected. Fetal chromosome karyotype analysis showed that 16 cases were normal and 1 case diagnosed as Down syndrome.@*CONCLUSION@#Thalassemia screening in pre-marital and pre-pregnancy, and prenatal diagnosis can effectively reduce the birth of children with thalassemia intermediate and thalassemia major. It is necessary to perform chromosome karyotype analysis at the same time as prenatal diagnosis of thalassemia gene in order to avoid fetus with abnormal chromosome.

ABSTRACT

OBJECTIVE@#To analyze the efficacy of children with B-cell acute lymphoblastic leukemia (B-ALL) without prognostic fusion genes treated by CCLG-ALL 2008, and investigate the related factors affecting the recurrence of the patients.@*METHODS@#B-ALL patients without prognostic fusion genes treated by the protocol of CCLG-ALL 2008 in our hospital from March 2008 to December 2012 were retrospectively analyzed. Follow-up time was ended in August 31, 2019. The median follow-up time was 92 months (range 0-136 months). Kaplan-Meier was used to detect the RFS, and COX multivariate regression analysis was employed to identify the independent factors affecting the recurrence of the patients.@*RESULTS@#There were 140 males and 99 females enrolled in this study. The ratio of male to female was 1.41∶1. The median age was 4.4 years old and the median number of WBC at initial stage was 4.98×109/L. There were 77 cases relapsed during the observation while 162 without relapsed, 16 cases lost to follow-up and 72 cases died. The recurrence and mortality rate was 32.22% and 30.1%, respectively, in which 45 cases died of recurrence (62.5% of the total deaths). Univariate analysis showed that the age≥6 years old, WBC >100×109/L, the bone marrow blasts on day 15≥25%, the bone marrow minimal residual disease (MRD) at week 12 >10-4, and the higher risk were the main factors affecting the recurrence of the patients (P<0.05). Multivariate COX regression analysis showed that age≥6 years old, WBC >100×109/L, bone marrow MRD >10-4 at the 12th week were the independent risk factors affecting recurrence of the patients.@*CONCLUSION@#Age, initial WBC, and bone marrow MRD at the 12th week were correlated with recurrence in children with B-ALL without prognostic fusion genes, which can be used as prognostic indices of recurrence risk in clinical.

ABSTRACT

Objective To discuss the epidemiological characteristics of the dynamic changes of serum FT3, FT4, and TSH levels in patients with hemorrhagic stroke under the age of 45, and to discuss the prognostic evaluation effects and influencing factors of these indicators. Methods From January 2017 to January 2020, 227 patients with multicenter hemorrhagic stroke in our hospital were selected for analysis. Collect and analyze prognosis (death, rebleeding, no adverse prognosis) at baseline and 12 months of follow-up; monitor serum FT3, FT4, and TSH levels during treatment at the same time during follow-up, 7 days after treatment, and 14 days after treatment. Observe the trend characteristics of dynamic changes. The assay method is enzyme-linked immunosorbent assay. At the end of the follow-up, the subjects were divided into three groups: death, rebleeding, and no adverse prognosis according to the prognostic outcome of the 12-month short-term follow-up. The epidemiological characteristics of patients with different prognosis and the dynamic change trend of FT3, FT4 and TSH in the same serum were compared. The interconnectedness. Results There were no statistically significant differences in gender and age between the three groups (P>0.05), but the differences in hypertension, hyperglycemia, and hyperlipidemia were statistically significant (P0.05). The FT4 level of the case group was significantly higher than that of the control group at all times (P0.05). The TSH level of the case group was significantly higher than that of the control group at all times (P0.05). With the decrease of the patient's age, the serum FT3 level has a gradually increasing trend, and the serum FT4, TSH level, mortality and rebleeding rate have a gradually decreasing trend (P<0.05). Conclusion The continuous decrease of FT3 level and the continuous increase of FT4 and TSH levels are potentially associated with the poor prognosis of patients with hemorrhagic stroke, which is worthy of clinical attention.
