Objective To observe the clinical efficacy of therapy of resolving blood stasis and tranquilizing mind in the treatment of insomnia with internal blockage of blood stasis type.Methods A parallel randomized controlled trial was conducted on 88 cases of insomnia patients with internal blockage of blood stasis type who admitted to Bao'an Traditional Chinese Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine from January 2024 to June 2024.The patients were randomly divided into an observation group and a control group,with 44 cases in each group.The observation group was treated with the self-made Huayu Anshen Prescription(modified Xuefu Zhuyu Decoction)orally following the therapy of resolving blood stasis and tranquilizing mind,while the control group was treated with Dexzopiclone Tablets orally.The course of treatment for the two groups covered four weeks.The changes in the scores of traditional Chinese medicine(TCM)syndrome,Pittsburgh Sleep Quality Index(PSQI),Self-Rating Depression Scale(SDS),and Self-Rating Anxiety Scale(SAS)in the two groups before and after treatment were observed,and then the clinical efficacy and medication safety of the patients in the two groups were evaluated.Results(1)After four weeks of treatment,the total effective rate of the observation group was 86.36%(38/44)and that of the control group was 70.45%(31/44),and the intergroup comparison showed that the clinical efficacy of the observation group was significantly superior to that of the control group,the difference being statistically significant(χ2=8.080,P<0.05).(2)After treatment,the scores of TCM syndrome,PSQI,SDS,and SAS of patients in the two groups were all significantly decreased compared with those before treatment(P<0.01),and the decrease in the observation group was significantly superior to that in the control group,the differences all being statistically significant(P<0.05).(3)During the treatment,there were no obvious adverse reactions occurred in the two groups,with higher safety.Conclusion Therapy of resolving blood stasis and tranquilizing mind for treating insomnia with internal blockage of blood stasis type can effectively alleviate patients'clinical symptoms,improve their sleep quality and relieve depression and anxiety,with stronger clinical efficacy and higher safety.

Objective To investigate the clinical efficacy of Xiaozhi Tea(composed of Eupatorii Herba,Nelumbinis Folium,Chrysanthemi Flos,Cassiae Semen,Crataegi Fructus,bran-fried Atractylodis Macrocephalae Rhizoma,Poria,Pseudostellariae Radix,Citri Reticulatae Pericarpium,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle)combined with Atorvastatin Calcium Tablets for the treatment of hyperlipidemia patients with turbid phlegm obstruction syndrome.Methods A retrospective cohort study was conducted in 200 hyperlipidemia patients with turbid phlegm obstruction syndrome who visited the outpatient department of Shenzhen Bao'an Traditional Chinese Medicine Hospital Group from September 2023 to September 2024.The patients were equally divided into a trial group and a control group based on the treatment regimen,with 100 cases in each group.The control group received oral use of Atorvastatin Calcium Tablets alone,while the trial group received Xiaozhi Tea in addition to Atorvastatin Calcium Tablets orally,both groups were treated for 8 weeks.Changes in traditional Chinese medicine(TCM)syndrome scores and lipid profiles of total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C)in the two groups were observed before and after treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)There were 3 patients in the control group dropping out due to lack of follow-up data,leaving 197 patients who eventually completed the study,100 cases in the trial group and 97 cases in the control group.(2)After 8 weeks of treatment,the total effective rate in the trial group was 97.00%(97/100)and that in the control group was 87.63%(85/97).The intergroup comparison(tested by chi-square test)showed that the trial group showed significantly stronger efficacy than the control group(P＜0.05).(3)Both groups exhibited significant reductions in TCM syndrome scores after treatment in comparison with those before treatment(P＜0.05),and a more pronounced reduction was presented in the trial group(P＜0.05).(4)Both groups showed decreased TC,TG,and LDL-C levels(P＜0.05)and increased HDL-C level after treatment in comparison with those before treatment(P＜0.05).The trial group demonstrated more obvious reduction of TC,TG,LDL-C,and more obvious elevation of HDL-C than the control group(P＜0.05).(5)In terms of safety,no severe adverse reactions occurred in either group.The incidence of adverse reactions in the trial group was 1.00%(1/100)and that in the control group was 2.06%(2/97),with no statistically significant difference between groups(P＞0.05).Conclusion Xiaozhi Tea combined with Atorvastatin Calcium Tablets exerts certain efficacy in treating hyperlipidemia with turbid phlegm obstruction syndrome,and is effective on significantly improving lipid profiles and clinical symptoms.The combination therapy demonstrates superior efficacy compared to Atorvastatin Calcium Tablets alone.

Small intestinal bacterial overgrowth（SIBO）is a clinically common but poorly recognized disease with clinical symptoms that overlap with those of functional gastrointestinal disorders（FGID）. FGID is a common risk factor for the occurrence of SIBO，and its SIBO incidence rate is significantly higher than that of healthy people，and has a certain correlation. Intestinal microbiota dysbiosis（including SIBO）plays an important role in the pathophysiology of FGID. At present，the diagnosis and treatment of SIBO still face challenges，and the treatment plan of FGID is gradually introduced into the treatment of SIBO. SIBO and FGID are closely related in clinical manifestations，incidence rate，pathophysiology，treatment and other aspects，but there is little research on the relationship between them. Prospective and large-scale clinical research is still needed to improve understanding and diagnostic accuracy.This article reviews the research progress on the relationship between SIBO and FGID.

Four novel β-galactoside prodrugs were designed and synthesized from anthraquinones HAQ-OH and AQ-OH in an attempt to use the prodrugs to selectively release superoxide anion (O2−) in cancer cells and to achieve selected anticancer activity by utilizing the Warburg effect and the elevated level of β-galactosidase in certain cancer cells. Cellular assays showed that the prodrugs Gal-HAQ and Gal-AQ selectively inhibited the proliferation and induced apoptosis of ovarian cancer OVCAR-3 cells overexpressing β-galactosidase. Using O2− fluorescent probe, it was found that in OVCAR-3 cells Gal-HAQ and Gal-AQ could time-dependently release O2−, which was essential for their anticancer activity. Furthermore, it was found that Gal-HAQ and Gal-AQ were effective senolytics toward senescent cells overexpressing β-galactosidase without affecting the viability of corresponding non-senescent cells, further confirming the β-galactosidase-dependent cytotoxicity of the prodrugs. In conclusion, Gal-HAQ and Gal-AQ, which release O2− in response to β-galactosidase, are expected to serve as candidate prodrugs targeting cancer cells.

Objective:This study aims to investigate the relationship between plague epidemics and environmental factors in Lincang City.Methods:Epidemiological survey data and environmental factors (including altitude, temperature, rainfall, and season) from plague occurrence sites in Lincang City from 1990 to 2020 were collected from Lincang Center for Disease Control and Prevention and the data sharing platform of the data sharing service network of the China Meteorological Administration, and analyzed using multiple correspondence analysis (MCA).Results:From 1990 to 2005, a total of 38 outbreaks of plague among rodents had been reported, 17 of which involved human beings. Since 2006, the plague had entered a dormant period, with no further epidemics reported up to 2020. The plague epidemic in Lincang City exhibited a clear seasonal variation, with the primary epidemic season occurred from autumn to early winter, peaking in September and October. Furthermore, the plague epidemic in Lincang City exhibited a pronounced spatial aggregation, with the primary affected regions including Linxiang County, Gengma Dai and Va Autonomous County, Zhenkang County, and Yun County. MCA showed that the Cronbach' α coefficients of all variables in the first and second dimensions were 0.87 and 0.82, respectively, and the characteristic roots were 3.27 and 2.91, respectively. The cumulative contribution rate of the two dimensions was 84.60%. Plague outbreaks were more likely in winter in areas at altitudes of > 1 400 - 1 650 m with 1 000 - 1 200 mm average annual rainfall and 16.0 - 17.9 ℃ average annual temperature, with increased severity. Regions at altitudes of > 500 - 700 m and > 900 - 1 150 m, with average annual rainfall of < 1 000, 1 201 - 1 400 and > 1 600 mm and average annual temperature of 18.0 - 19.9 ℃, showed a higher susceptibility to plague outbreaks, with notably pronounced incidences.Conclusions:The prevalence of plague epidemics is closely related to the local climatic conditions of natural foci in Lincang City. Therefore, it is imperative to enhance the monitoring of these climatic conditions, particularly meteorological data, to facilitate more effective prevention and control of plague outbreaks.

Objective:To investigate the clinicopathological characteristics of lung transplantation and post-transplantation changes in patients with pneumoconiosis.Methods:A retrospective study was conducted to analyze the clinical and pathological data of 28 patients with pulmonary silicosis who underwent lung transplantation and were managed at the Department of Internal Medicine, Henan Provincial People′s Hospital, Zhengzhou, China from January 2015 to December 2024. Among them, 8 patients underwent lung biopsy 6-20 months after transplantation to evaluate the histopathological changes of the recipient and the donor lungs post-transplantation. The expression of relevant indicators was examined using immunohistochemical EnVision staining, while presence of microorganisms was assessed using histochemical special staining. The patients were all followed up.Results:Among the 28 patients with pneumoconiosis who underwent lung transplantation, 26 were male and 2 were female, with a male-to-female ratio of 13∶1. Their ages ranged from 23 to 68 years, median 50.0 (46.0, 53.5) years. They were diagnosed with pneumoconiosis at local occupational disease prevention and control centers for 3 to 15 years (mean, 9.65 years), including 13 left single lung transplants and 15 right single lung transplants. Gross examination showed fleshy nodules with irregular cystic cavities at the periphery. The cut surfaces exhibited gray-brown color and firm texture. Microscopically, most alveolar structures of the lung were obliterated, with nodular or diffuse proliferation of collagen fibers accompanied by hyaline degeneration. Focal massive carbon dust deposition and massive silicotic fibrosis were observed, surrounded by lung parenchyma with emphysematous changes and localized bullae formation. Seven patients underwent re-biopsy after transplantation that showed extensive infiltration of inflammatory cells. In 4 cases, microscopy revealed complete coagulative necrosis, with negative acid-fast staining and TB-DNA results. Of the 4 cases, 3 cases exhibited Aspergillus infection confirmed by Grocott′s methenamine silver and PAS stains, while 2 cases showed chronic bronchitis with squamous metaplasia. Follow-up revealed that 8 patients died of acute respiratory failure due to severe infection, while the remaining 20 demonstrated significant postoperative improvement in lung function.Conclusions:For patients with advanced pulmonary dust deposition disease who undergo lung transplantation, it is necessary to conduct standardized sampling and pathological assessment of the recipient lungs. In the early post-transplant period, the complications of re-biopsy tissues are mainly fungal infections. The combination of morphological manifestations and immunohistochemical detection is helpful to distinguish infection from rejection reactions. At the same time, it is essential to integrate clinical information and laboratory results to provide post-transplantation pathological assessment for individualized treatment.

[Objective] To investigate the correlation between human leukocyte antigen (HLA) gene polymorphism and hepatitis B virus (HBV) infection. [Methods] Venous blood samples were collected from 501 healthy individuals undergoing physical examinations at Yan’an Hospital in Kunming, Yunnan Province. Enzyme linked immunosorbent assay (ELISA) was used to detect HBV halves. Based on the results of HBV half detection, the patients were divided into three groups: HBV carrier group, previous infection group, and healthy control group. The HLA-A antigen genotype was detected using polymerase chain reaction with sequence specific primers (PCR-SSP) genotyping technology, and the distribution frequency of HLA-A gene polymorphism was compared between HBV carrier group and healthy control group, as well as between previous infection group and healthy control group. SPSS17.0 software was used for data statistical analysis. [Results] In the healthy control group, the HLA-A2 positivity rate was 47.49%, and the allele frequency was 31.29%.The overall frequency of gene distribution in the healthy control group was consistent with the HLA-A allele table commonly and confirmed in China published by the Chinese Bone Marrow Bank. The HLA-A2 positivity rate and allele frequency in the HBV carrier group were 63.04% and 42.23%, respectively; The difference in HLA-A2 positivity rate and allele frequency among carriers was statistically significant (P<0.05). the HLA-A2 positivity rate and allele frequency in the HBV previous infection group were 56.14% and 35.97%, respectively, which did not significantly differ from those in the healthy control group (P>0.05). [Conclusion] HLA-A2 gene may be a susceptibility gene for chronic hepatitis B HBV carriers.
