Objective: To investigate the survival rate of female breast cancer patients in Panyu District, Guangzhou City, so as to provide the basis for improving the prognosis of breast cancer patients. Methods: Basic information including age, clinical stage and surgical treatment of female breast cancer patients registered in Panyu District and diagnosed in 2017 were collected through the Guangzhou Municipal Cancer Registration and Reporting Management System, and were followed up until December 31, 2022. The survival rate was calculated using the life table. Factors affecting survival time among female breast cancer patients were analyzed using a multivariable Cox proportional hazard regression model. Results: A total of 227 female breast cancer patients were reported in Panyu District in 2017, and had a median age of 51 (interquartile range, 17) years. There were 43 cases (18.94%) in stage Ⅰ, 55 cases (24.23%) in stage Ⅱ, 63 cases (27.75%) in stage Ⅲ, 27 cases (11.89%) in stage Ⅳ, and 39 cases (17.18%) with unknown staging. Surgical treatment was performed in 204 cases (89.87%), and chemotherapy was administered in 73 cases (32.16%). By December 31, 2022, there were 40 deaths and 14 patients lost to follow-up. The one-year, three-year and five-year survival rates were 96.44%, 87.45% and 82.87%, respectively. Multivariable Cox proportional hazard regression analysis showed that older age (HR=1.023, 95%CI: 1.002-1.046), clinical stage Ⅲ (HR=10.050, 95%CI: 1.324-76.270) or IV (HR=42.663, 95%CI: 5.588-325.742) were associated with a higher risk of mortality in female breast cancer patients, while surgical treatment (HR=0.278, 95%CI: 0.130-0.598) was associated with a lower risk of mortality. Conclusions The five-year survival rate of female breast cancer patients in Panyu District was 82.87%. Age, clinical stage and surgical treatment were the main influencing factors for the survival time of female breast cancer patients.

Objective To investigate the correlation of solute carrier protein 17 family member 1 (SLC17A1) gene single nucleotide polymorphisms (SNPs) and susceptibility to hyperuricemia (HUA) in automotive manufacturing workers. Methods A total of 192 Han male workers diagnosed with HUA were selected as the case group, 192 Han male workers without HUA from the same enterprises were selected as the control group. These workers were determined by the matching factor of age, total length of service, and body mass index by the 1∶1 case-control study method. Peripheral venous blood from the workers was collected for DNA extraction. Two SNPs of SLC17A1 were genotyped by MassArray system. Results The gene frequency distributions of SLC17A1 rs2096386 and rs1183201 of workers in the control group were in consistent with the Hardy-Weinberg equilibrium test (both P>0.05). The allele frequency distribution of rs2096386, and the genotype and allele frequency distribution of rs1183201 were significantly different between workers in the two groups (all P<0.05). There was no significant difference in genotype frequency distribution of rs2096386 between workers in the two groups (P>0.05). The results of conditional logistic regression analysis showed that workers with G allele at rs2096386 increased the risk of HUA [odds ratio (OR)=1.43, 95% confidence interval (CI)=1.01-2.04], workers with T allele at rs1183201 increased the risk of HUA (OR=2.03, 95%CI =1.29-3.19), after adjusting for confounding factors such as serum creatinine, blood urea nitrogen, alanin aminotransferase and aspartate aminotransferase. While workers with TA and TA+AA genotypes at rs1183201 had a lower risk of HUA than those with TT genotype (OR=0.51, 95%CI =0.30-0.85; OR=0.50, 95%CI =0.30-0.83), workers with TA genotype at rs1183201 had a lower risk of HUA than those with TT+AA genotype (OR=0.53, 95%CI =0.32-0.88). Conclusion The polymorphisms at rs2096386 and rs1183201 of SLC17A1 gene may be correlated with HUA susceptibility among automobile manufacturing workers in Guangzhou City.

The gut microbiota regulates intestinal nutrient absorption, participates in modulating host glucolipid metabolism, and contributes to ameliorating glucolipid metabolism disorder. Dysbiosis of the gut microbiota can compromise the integrity of the intestinal mucosal barrier, induce inflammatory responses, and exacerbate insulin resistance and abnormal lipid metabolism in the host. Dangua Humai Oral Liquid, a hospital-developed formulation for regulating glucolipid metabolism, has been granted a national invention patent and demonstrates significant clinical efficacy. This study aimed to investigate the effects of Dangua Humai Oral Liquid on gut microbiota and the intestinal mucosal barrier in a mouse model with glucolipid metabolism disorder. A glucolipid metabolism disorder model was established by feeding mice a high-glucose and high-fat diet. The mice were divided into a normal group, a model group, and a treatment group, with eight mice in each group. The treatment group received a daily gavage of Dangua Humai Oral Liquid(20 g·kg~(-1)), while the normal group and model group were given an equivalent volume of sterile water. After 15 weeks of intervention, glucolipid metabolism, intestinal mucosal barrier function, and inflammatory responses were evaluated. Metagenomics and untargeted metabolomics were employed to analyze changes in gut microbiota and associated metabolic pathways. Significant differences were observed between the indicators of the normal group and the model group. Compared with the model group, the treatment group exhibited marked improvements in glucolipid metabolism disorder, alleviated pathological damage in the liver and small intestine tissue, elevated expression of recombinant claudin 1(CLDN1), occluding(OCLN), and zonula occludens 1(ZO-1) in the small intestine tissue, and reduced serum levels of inflammatory factors lipopolysaccharides(LPS), lipopolysaccharide-binding protein(LBP), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α). At the phylum level, the relative abundance of Bacteroidota decreased, while that of Firmicutes increased. Lipid-related metabolic pathways were significantly altered. In conclusion, based on the successful establishment of the mouse model of glucolipid metabolism disorder, this study confirmed that Dangua Humai Oral Liquid effectively modulates gut microbiota and mucosal barrier function, reduces serum inflammatory factor levels, and regulates lipid-related metabolic pathways, thereby ameliorating glucolipid metabolism disorder.

OBJECTIVE To understand the information labeling of children’s medication in the instructions of antitussive and expectorant drugs commonly used in children’s medical institutions， analyze the existing problems， and propose relevant suggestions. METHODS The instructions for 100 antitussive and expectorant drugs commonly used in 20 tertiary children’s hospitals （centers） and 14 maternal and child health hospitals （centers） with regional representativeness in China were collected， and the information labeling of children’s medication in the instructions was investigated and analyzed. RESULTS There were only 7 kinds of antitussive and expectorant drugs for children， and the others were non-specific drugs for children. Among antitussive and expectorant drugs， tablets accounted for 18.00%， injections for 18.00%， and capsules for 4.00%. Among 100 antitussive and expectorant drugs， 72 （72.00%） labeled the usage and dosage for children， 63 （63.00%） labeled the medication items for children， 59 （59.00%） indicated the information of children in the precautions， and pharmacokinetic parameters for children were absent. Compared with imported antitussive and expectorant drugs or the drugs manufactured by joint ventures， there were many missing labeling of medication information for children with Chinese drugs. Among 63 kinds of drug instructions labeled with medication items for children， various instructions information had little guiding significance. CONCLUSIONS There is a lack of labeling in the instructions of antitussive and expectorant drugs for children， and the proportion of special drugs for children remains low. Pediatric drug information in the instructions has little guiding significance for pediatric medication. Relevant departments should further promote the completeness of pediatric medication information in the instructions of antitussive and expectorant drugs to ensure the rational use of children’s medication.

OBJECTIVE To observe the clinical efficacy of Huatan Tongluo Decoction in the treatment of post-stroke cognitive impairment(PSCI)with phlegm stasis obstructing collaterals syndrome,and its influence on the serum brain-derived neurotrophic fac-tor(BDNF)pathway-related factors.METHODS Sixty patients who met the inclusion criteria were collected and randomly divided into a control group and a treatment group with 30 patients each.The control group was given basic treatment and nimodipine,while the treatment group was given Huatan Tongluo Decoction on the basis of the treatment in the control group.The treatment course for both groups was 4 weeks.Changes in Mini-Mental State Examination(MMSE),TCM syndrome scores and serum levels of BDNF,nuclear transcription factor κB(NF-κB),B lymphocyte tumor-2(Bcl-2)and Bcl-2-associated X protein(Bax)were compared between the two groups before and after treatment.The TCM clinical efficacy in the two groups of patients was evaluated after treatment,and the oc-currence of adverse reactions was observed during treatment.RESULTS After treatment,the MMSE scores of the patients in the two groups increased significantly,the total TCM syndrome scores decreased significantly(P<0.01),and the treatment group was better than the control group(P<0.01);the serum BDNF,NF-κB,and Bcl-2 levels of the two groups of patients were significantly in-creased(P<0.05,P<0.01),and the Bax level was significantly decreased(P<0.01).The treatment group was better than the control group(P<0.01).CONCLUSION Huatan Tongluo Decoction can improve the clinical symptoms of PSCI patients with phlegm stasis obstructing collaterals,and is safe and effective.Its therapeutic mechanism may be related to regulating the BDNF pathway to protect nerve cells and inhibit nerve cell apoptosis.

Objective To investigate the clinical efficacy of Guiyuan Shujin Mixture in the treatment of patients with lumbar disc herniation(LDH)and to explore its possible therapeutic mechanism.Methods Sixty-eight patients with LDH of qi stagnation and blood stasis syndrome were randomly divided into trial group and control group,with 34 cases in each group.The control group was treated with Celecoxib Tablets and Mecobalamin Tablets orally,and the trial group was treated with Guiyuan Shujin Mixture on the basis of treatment for the control group.The course of treatment lasted for 4 weeks.Before and after treatment,the two groups were observed in the changes of the Visual Analogue Scale(VAS)score of low back pain and lower limb pain,Oswestry Disability Index(ODI)score,modified Japanese Orthopedic Association(JOA)score,serum levels of inflammatory factors of tumor necrosis factor α(TNF-α),interleukin 6(IL-6)and interleukin 1β(IL-1β),and serum nuclear factor-κB p65(NF-κB p65)level.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)During the trial,one case fell off in the trial group and 3 cases fell off in the control group.Eventually,33 cases in the trial group and 31 cases in the control group were included for the efficacy statistics.(2)After 4 weeks of treatment,the total effective rate of the trial group was 96.97%(32/33),and that of the control group was 87.10%(27/31).The intergroup comparison(tested by rank sum test)showed that the curative effect of the trial group was significantly superior to that of the control group(P＜0.05).(3)After treatment,the VAS score and ODI score of low back pain and lower limb pain in the two groups were lower than those before treatment(P＜0.05 or P＜0.01),and the modified JOA score was higher than that before treatment(P＜0.01).The decrease of VAS score and ODI score of low back pain and lower limb pain and the increase of modified JOA score in the trial group were significantly superior to those in the control group(P＜0.05 or P＜0.01).(4)After treatment,the serum levels of inflammation-related indicators of TNF-α,IL-6,IL-1β and NF-κB p65 in the two groups were lower than those before treatment(P＜0.01),and the decrease in the trial group was significantly superior to that in the control group(P＜0.01).(5)During the treatment,the incidence of adverse events in the trial group was 2.94%(1/34)and that in the control group was 8.82%(3/34),and the difference between the two groups was not significant(P＞0.05).Conclusion Guiyuan Shujin Mixture exerts certain effect in the treatment of LDH patients with qi stagnation and blood stasis syndrome.It can effectively relieve the pain symptoms of patients,improve the lumbar function of patients,and reduce the expression levels of serum inflammatory factors and NF-κB p65.The mechanism may be related with the decrease of the level of inflammatory factors and with the inhibition of the activation of NF-κB signaling pathway.

Objective To observe the clinical efficacy of Shuangye San(the prescription mainly composed of Mori Folium and Nelumbinis Folium)in the treatment of type 2 diabetes mellitus(T2DM)complicated with non-alcoholic fatty liver disease(NAFLD)of spleen deficiency and phlegm stasis type.Methods A total of 80 patients with T2DM complicated with NAFLD of spleen deficiency and phlegm stasis type were randomly divided into a treatment group and a control group,with 40 cases in each group.The control group was treated with conventional western medicine for lowering blood glucose and lipid,protecting liver and lowering enzymes.The treatment group was treated with the granules of Shuangye San orally on the basis of treatment for the control group.The course of treatment lasted for three months.The changes of traditional Chinese medicine(TCM)syndrome scores,homeostasis model assessment of insulin resistance(HOMA-IR),fasting insulin(FINS),fasting blood glucose(FBG),2-hour postprandial blood glucose(2hPG),glycosylated hemoglobin(HbA1C),total cholesterol(TC),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),liver function indicators and B-ultrasound grading of fatty liver 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)After three months of treatment,the total effective rate of the treatment group was 85.00％(34/40),and that of the control group was 70.00％(28/40).The intergroup comparison(tested by chi-square test)showed that the efficacy of the treatment group was significantly superior to that of the control group(P＜0.01).(2)After treatment,the scores of TCM symptoms of obese physique,heaviness and weakness in the limbs,shortness of breath and unwilling to talk,tightness and stabbing pain in the chest,abdominal distension and poor appetite in the two groups were decreased compared with those before treatment(P＜0.05),and the decrease of TCM syndrome scores in the treatment group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the levels of glucose and lipid metabolism indicators of FINS,HOMA-IR,FBG,2hPG,HbA1C,TC,TG and LDL-C in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the level of HDL-C was significantly increased compared with that before treatment(P＜0.05).The decrease of FINS,HOMA-IR,FBG,2hPG,HbA1C,TC,TG and LDL-C levels and the increase of HDL-C levels in the treatment group were significantly superior to those in the control group(P＜0.05).(4)After treatment,the levels of liver function indicators of alanine aminotransferase(ALT),aspartate aminotransferase(AST)and gamma-glutamyl transpeptidase(GGT)in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease of liver function indicators in the treatment group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the B-ultrasound grading of fatty liver of the two groups was significantly improved compared with that before treatment(P＜0.05),and the improvement of fatty liver B-ultrasound grading in the treatment group was significantly superior to that in the control group,and the difference was statistically significant(P＜0.05).(6)During the treatment,there were no adverse reactions such as impairment of liver and kidney function and abnormalities in routine blood,urine and stool test in the two groups.Conclusion Shuangye San exerts certain effect in the treatment of T2DM complicated with NAFLD of spleen deficiency and phlegm stasis type.It can alleviate the clinical symptoms of patients,correct the disorder of glucose and lipid metabolism,and improve liver function and fatty liver B-ultrasound grading.

Objective:Peritoneal free cancer cells can negatively impact disease progression and patient outcomes in gastric cancer.This study aimed to investigate the feasibility of using golden-angle radial sampling dynamic contrast-enhanced magnetic resonance imaging(GRASP DCE-MRI)to predict the presence of peritoneal free cancer cells in gastric cancer patients.Methods:All enrolled patients were consecutively divided into analysis and validation groups.Preoperative magnetic resonance imaging(MRI)scans and perfusion were performed in patients with gastric cancer undergoing surgery,and peritoneal lavage specimens were collected for examination.Based on the peritoneal lavage cytology(PLC)results,patients were divided into negative and positive lavage fluid groups.The data collected included clinical and MR information.A nomogram prediction model was constructed to predict the positive rate of peritoneal lavage fluid,and the validity of the model was verified based on data from the verification group.Results:There was no statistical difference between the proportion of PLC-positive cases predicted by GRASP DCE-MR and the actual PLC test.MR tumor stage,tumor thickness,and perfusion parameter Tofts-Ketty model volume transfer constant(Ktrans)were independent predictors of positive peritoneal lavage fluid.The nomogram model featured a concordance index(C-index)of 0.785 and 0.742 for the modeling and validation groups,respectively.Conclusions:GRASP DCE-MR could effectively predict peritoneal free cancer cells in gastric cancer patients.The nomogram model constructed using these predictors may help clinicians to better predict the risk of peritoneal free cancer cells being present in gastric cancer patients.

Objective:To explore the effects of online mindfulness-based stress reduction(MBSR)on the anxiety and depression status,and quality of life in the caregivers of patients with severe mental disorders.Methods:Ninety-three caregivers for patients with schizophrenia or bipolar disorder,who were hospitalized in Yunnan Provincial Mental Hospital in March 2021,were enrolled and randomly divided into control group(n=47)and MBSR intervention group(n=46).Both groups received basic health education and rehabilitation skill training,while the intervention group received additional online MBSR for 8 weeks.The anxiety and depression status,and the quality of life of the caregivers were evaluated by Self-rating Anxiety Scale(SAS),Self-rating Depression Scale(SDS)and the 36-item Short Form Health Survey(SF-36)before and 8 weeks after intervention,respectively.Results:Thirteen caregivers dropped out of the study,and 80 subjects(40 in each group)were included in the final analysis.At the baseline,there were no significant differences in SAS,SDS and SF-36 scores between two groups(all P>0.05).Compared with the baseline,SAS and SDS scores in the intervention group significantly decreased after 8 weeks of intervention(both P<0.01)and were significantly lower than those in the control group(both P<0.01).There were no significant changes in the control group(all P>0.05).Except the physiological function dimension,the total score and the scores of each dimension of SF-36 in the intervention group were significantly increased after 8-week intervention(all P<0.05),and were significantly higher than those in the control group(all P<0.01).There were no significant changes in the control group before and after intervention(all P>0.05).Conclusion:Online MBSR can reduce the anxiety and depression levels,improve the quality of life in the caregivers of patients with severe mental disorders.

AIM:To explore the roles and associations of hepatocyte nuclear factor 4 alpha(HNF4A)and mu-protocadherin(MUCDHL)in the kidney of diabetic mice.METHODS:(1)A cohort of six 12-week-old db/m mice and six db/db mice were selected and maintained on a standard diet until 16 weeks.The protein levels of fibronectin(FN),collagen type III(Col-III),E-cadherin,α-smooth muscle actin(α-SMA),HNF4A,Snail and MUCDHL in renal tissues were scrutinized using Western blot.Immunohistochemical staining was conducted to observe the distribution and expres-sion of FN,HNF4A and MUCDHL.(2)Mouse renal tubular epithelial cells(mRTEC)were cultured in vitro and catego-rized into groups:normal glucose(NG)group,high glucose(HG)group,overexpression control groups(NG+vector and HG+vector),overexpression groups(NG+OE-MUCDHL,HG+OE-MUCDHL,NG+OE-HNF4A and HG+OE-HNF4A),knockdown control groups(NG+control and HG+control),and knockdown groups(NG+si-MUCDHL,HG+si-MUCDHL,NG+si-HNF4A and HG+si-HNF4A).The relevant protein levels were also detected by Western blot.RESULTS:(1)In db/db group,elevated body weight,blood glucose and urine albumin-to-creatinine ratio(UACR)indicated significant re-nal injury.Compared with db/m group,the mice in db/db group exhibited increased expression of FN,Col-III,α-SMA and Snail,and decreased expression of E-cadherin,HNF4A and MUCDHL.MUCDHL was predominantly expressed in the apical membrane of renal tubular epithelial cells,FN in the tubular mesenchyme,and HNF4A in the plasma and nu-cleus of renal tubular cells.(2)In HG group,there was an up-regulation in the expression of fibrosis-related proteins and a down-regulation in the expression of E-cadherin,HNF4A and MUCDHL compared with NG group.Overexpression of MUCDHL led to a decrease in the expression of FN,Col-III,α-SMA and Snail proteins,an increase in the expression of E-cadherin and MUCDHL proteins,and unaltered expression of HNF4A.Knockdown of MUCDHL resulted in a reversal of the aforementioned effects,with HNF4A expression remaining unaltered.Overexpression of HNF4A led to an increased ex-pression of MUCDHL,and the expression changes of the remaining indicators were consistent with the overexpression of MUCDHL.Knockdown of HNF4A reversed the aforementioned effects.MUCDHL may represent a downstream target gene of HNF4A.CONCLUSION:The diminished expression of HNF4A and MUCDHL in the renal tubules of diabetic mice implies their involvement in the progression of renal fibrosis in diabetic kidney disease(DKD).HNF4A may potentially impede the progression of renal fibrosis in DKD by up-regulating the expression of MUCDHL.
