This paper summarizes Professor LIU Shangyi's clinical experience in treating acute mastitis based on the "membrane collaterals" theory. It is considered that constraint and stagnation of the membrane collaterrals is the primary pathogenic factor， with damp， heat， phlegm， and stasis being the secondary manifestations. If untreated， the condition can progress to heat toxin injuring the membrane. In treatment， the emphasis is diffusing and unblocking membrane collaterals， unblocking breast and relieving constraint. The clinical course of the disease can be divided into three stages including the early stage with mild constraint heat， the middle stage with escalating toxic heat， and the later stage with a decline of pathogens but deficiency of healthy qi. In correspondence， self-made Tongru Formula （通乳方） for diffusing membrane and venting constraint， self-made Toumo Jiedu Formula （透膜解毒方） for unblocking membrane and relieving toxin， and Tuoli Xiaodu Powder （托里消毒散） with modifications for restoring membrane and rectifying healthy qi should be used， respectively.

In response to the current problems in the traditional methods used for teaching the course of "maternal, child, and adolescent health", including the monotony of teaching modes, poor learning outcomes, limited use of information technology-based teaching, and the need for improved faculty professionalism, this study explored the reform and practice of teaching modes for this course. Teaching reform centered on a task-driven pre-class learning guide, supported by the development of a resource platform. This platform was used to assign pre-class and post-class tasks. An information technology-based platform facilitated teaching implementation during class. Systematical analysis and evaluation were performed on the teaching process and implementation effects. By continuously optimizing course design, adjusting teaching strategies, and improving the autonomy and learning efficiency of students, the system can be used to improve teaching effectiveness and quality. This system provides a reference for information technology-based teaching reform in similar courses.

Objective:To investigate the effects of combination therapy with aqueous extract of corn silk(CS)and training on exercise capacity and glycolipid metabolism in mice with metabolic syndrome(MS).Methods:In this study,db/db mice were used as the animal model of MS.The mice were administered aqueous extract of CS via gavage and subjected to different intensities of training for 12 weeks(3 months).The specific experimental design was as follows:24 db/db mice were randomly divided into four groups on average:negative control group(NC),aqueous extract of CS group(CS),aqueous extract of CS+moderate-intensity training group(CS+MT),and CS aqueous extract of CS+high-intensity training group(CS+HT).The maximum running speed,forelimb grip strength,body weight and fasting blood glucose of mice were measured before and after treatment.After the intervention,oral glucose tolerance test(OGTT)and insulin tolerance test(ITT)were conducted to assess glucose metabolism,while serum triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C)levels were measured to evaluate lipid metabolism.Results:After 3 months of intervention,there were significant differences in the maximum running speed and forelimb grip strength among the four groups(P＜0.05).The maximum running speed and forelimb grip strength of CS group,CS+MT group and CS+HT group were higher than those of NC group(P＜0.05).The CS+MT group exhibited higher forelimb grip strength,and the CS+HT group showed higher maximum running speed and forelimb grip strength compared to the CS group(P＜0.05),while no significant difference was found between the CS+MT and CS+HT groups(P＞0.05).Significant differences in body weight were observed among the four groups after 3 months of intervention(P＜0.05).Specifically,the CS+MT and CS+HT groups exhibited significantly lower body weight compared to both the NC and CS groups(P＜0.05),with the CS+MT group having the lowest body weight(P＜0.05).Fasting blood glucose levels also differed significantly among the groups after 2 and 3 months of intervention(P＜0.05).The CS,CS+MT,and CS+HT groups had lower fasting blood glucose levels compared to the NC group(P＜0.05),with the CS+MT and CS+HT groups showing the lowest levels(P＜0.05).No significant difference was found between the CS+MT and CS+HT groups(P＞0.05).After 3 months of intervention,significant differences in the area under the curve(AUC)of OGTT and ITT were observed among the four groups(P＜0.05).The AUC of OGTT and ITT were significantly lower in the CS,CS+MT,and CS+HT groups compared to the NC group(P＜0.05).The CS+MT and CS+HT groups exhibited the lowest AUC values for both OGTT and ITT(P＜0.05),with the CS+MT group showing the lowest AUC for OGTT(P＜0.05).Significant differences in serum lipid levels were observed among the four groups after 3 months of intervention(P＜0.05).TG,TC,and LDL-C levels were significantly lower,while HDL-C levels were higher in the CS,CS+MT,and CS+HT groups compared to the NC group(P＜0.05).The CS+MT group had the lowest TG levels and the highest HDL-C levels compared to the CS+HT group(P＜0.05),with no significant differences in TC and LDL-C levels between these two groups(P＞0.05).Conclusion:Aqueous extract of CS combined with different intensity training can significantly improve the exercise capacity and glycolipid metabolism of MS mice and reduce body weight,especially CS combined with MT treatment is more effective in improving lipid metabolism.In addition,when combined with HT,aqueous extract of CS can also play an auxiliary role in reducing the side effects of high-intensity exercise and improving the therapeutic effect.

[Purpose]To analyze cancer incidence and mortality in Xinjiang cancer registration ar-eas in 2020 and the trends from 2016 to 2020.[Methods]Incidence and mortality data of cancer reported by four cancer registration areas in Xinjiang in 2020 were collected.Crude incidence and mortality rates,age-standardized incidence and mortality rates by Chinese standard population(ASIRC/ASMRC),and world standard population(ASIRW,ASMRW),and cumulative rate(0～74 years old)were calculated.The Chinese standard population(2000 national census)and Segi's world standard population were used for standardization.Joinpoint regression was applied to ana-lyze the trends of incidence and mortality from 2016 to 2020,and the average annual percentage change(AAPC)was calculated.[Results]In 2020,the crude incidence rate of cancer in Xinjiang cancer registration areas was 291.67/105(286.64/105 for male,296.64/105 for female),ASIRC and ASIRW were 190.43/105 and 206.58/105,and the cumulative incidence rate(0～74 years old)was 20.51％.The crude mortality rate was 185.58/105(2 1 8.79/105 for male,152.78/105 for female),ASMRC and ASMRW were 109.13/105 and 126.64/105,and the cumulative mortality rate(0～74 years old)was 11.54％.In 2020,the incidence and mortality rates increased with age,peaking in the age groups of 80～84 and ≥85 years old,respectively.Lung cancer was the leading cause of incidence(crude incidence rate:51.13/10s),followed by female breast cancer,thyroid cancer,colorectal cancer and stomach cancer.Lung cancer was also the leading cause of mortality(crude mortality rate:41.14/105),followed by liver cancer,colorectal cancer,stomach cancer and fe-male breast cancer.There was no significant change in the ASIRC/ASMRC from 2016 to 2020(incidence AAPC=2.95％,mortality AAPC=8.51％,both P＞0.05).[Conclusion]The incidence and mortality of cancer in Xinjiang cancer registration areas were stable from 2016 to 2020.Lung cancer,digestive system cancers(colorectal,gastric,liver cancers),and female breast cancer re-main the main cancers threatening the health of Xinjiang residents,indicating the need to strengthen screening and early diagnosis and treatment.

AIM To investigate the clinical effects of Yifei Tongluo Decoction combined with azithromycin on patients with childern severe Mycoplasma pneumoniae pneumonia due to Toxic Heat Blocking Lung.METHODS One hundred and fifty-six patients were randomly assigned into control group(78 cases)for 7-day administration of azithromycin,and observation group(78 cases)for 7-day administration of both Yifei Tongluo Decoction and azithromycin.The changes in clinical effects,disappearance time of local symptoms,mycoplasmas,pulmonary imaging score,Toxic Heat Blocking Lung score,pulmonary function indices(PEF,VPTEF,MMF,TPTEF),inflammatory factors(sB7-H3,Cgp-39,sICAM-1,CCL5),immune function indices(RBC-C3bR,RBC-ICR,CD3+,CD4+)and safety indices were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05),along with shorter disappearance time of local symptoms(P＜0.05).After the treatment,the two groups displayed decreased mycoplasmas,pulmonary imaging score,Toxic Heat Blocking Lung score,inflammatory factors,RBC-ICR(P＜0.05),and increased pulmonary function indices,RBC-C3bR,CD3+,CD4+(P＜0.05),especially for the observation group(P＜0.05).No obvious difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with childern severe Mycoplasma pneumoniae pneumonia due to Toxic Heat Blocking Lung,Yifei Tongluo Decoction combined with azithromycin can safely and effectively alleviate clinical symptoms,improve pulmonary functions,and reduce body inflammatory responses.

Objective To investigate the effect and mechanism of miR-195-5p on myocardial fibro-sis in rats with atrial fibrillation(AF).Methods A total of 72 male SD rats were randomly divid-ed into control group,AF group,negative control group,miR-195-5p inhibitor group,recombinant adeno-associated virus serotype 9(rAAV9)group(miR-195-5p inhibitor+rAAV9-negative con-trol),and combination group[miR-195-5p inhibitor+rAAV9-siRNA-SMAD homolog 7(Smad)],with 12 rats in each group.Except for the control group,the rats in the other groups were inflicted to construct AF model.After receiving corresponding intervention measures,elec-trocardiography was conducted to record the incidence and the duration of AF.HE staining and Masson staining were used to observe the pathological changes and fibrosis in the myocardial tis-sues,respectively.qRT-PCR was applied to detect the mRNA levels of miR-195-5p and Smad7,and Western blotting was performed to detect the expression of TGF-β1,Smad2,p-Smad2,Smad3,p-Smad3,Smad7,Collagen-Ⅰ and Collagen-Ⅲ in the myocardial tissues.Dual luciferase assay was used to verify the regulatory effect of miR-195-5p on Smad7.Results Compared with the control group,the AF group had significantly higher AF incidence(75.0％vs 0)and longer duration(27.02±2.65 s vs 0 s),larger collagen volume fraction(CVF)[(14.47±0.89)％vs(2.12±0.35)％],and increased expression levels of miR-195-5p(3.27±0.21 vs 1.00±0.10),TGF-β1(0.76±0.08 vs 0.23±0.04),Collagen-Ⅰ(0.58±0.07 vs 0.20±0.04),Collagen-Ⅲ(0.46±0.05 vs 0.11±0.02),p-Smad2/Smad2(0.92±0.10 vs 0.37±0.05),and p-Smad3/Smad3(0.65±0.06 vs 0.14±0.03),but notably decreased expression of Smad7 at mRNA(0.32±0.06 vs 1.02±0.09)and protein(0.19±0.03 vs 0.58±0.07)levels in the myocardial tissues(P＜0.05).The AF incidence and duration,CVF,miR-195-5p level,and protein levels of TGF-β1,Collagen-Ⅰ,Colla-gen-Ⅲ,p-Smad2/Smad2,and p-Smad3/Smad3 were significantly decreased,and the mRNA and protein levels of Smad7 were significantly increased in the miR-195-5p inhibitor group than the AF group and the negative control group(P＜0.05).The combined treatment increased the inci-dence and duration of AF,CVF,myocardial TGF-β1,Collagen-Ⅰ,Collagen-Ⅲ,p-Smad2/Smad2 and p-Smad3/Smad3 expression levels,and decreased the mRNA and protein expressions of Smad7 when compared with the miR-195-5p inhibitor group and the rAAV9 group(P＜0.05).Conclusion Down-regulation of miR-195-5p alleviates myocardial fibrosis in AF rats probably by targeting Smad7 to inhibit TGF-β1 signaling.

Aim To investigate the neuroprotective effect of Takeda G protein-coupled receptor-5(TGR5)activated by INT-777 on hypoxic-ischemic encephalop-athy(HIE)in neonatal rats.Methods Seven-day-old SD rats were randomly divided into the sham opera-tion group(Sham,S),model group(HIE,G),INT-777 low-dose(L),medium-dose(M),and high-dose(H)groups.The modified Rice-Vanucci method was used to construct the HIE model and Intranasal admin-istration 1 h after modeling.Short-term neurobehavioral tests were performed 48 h after modeling to evaluate the neurological function of neonatal rats,TTC staining was used to determine the volume of cerebral infarction,dry and wet specific gravity was used to determine the brain water content,ferrous ion kit was used to deter-mine the brain ferrous ion content,HE staining was used to observe the pathological damage of brain tis-sue,Nissl staining was used to observe the loss of Nissl substance,Transmission electron microscopy(TEM)was used to observe the mitochondrial morphological changes of cortical neurons,and Western blot was em-ployed to detect the expression of ferroptosis-related proteins TFR1 and GPX4.Results Compared with group S,group G had increased short-term neurobehav-ioral test consumption time,higher scores,increased cerebral infarct volume,brain water content,and brain ferrous iron content,significant brain tissue damage on the affected side,severe loss of Nissl substance,smaller neuronal mitochondria,decreased mitochondrial cris-tae,and increased expression of TFR1 and reduced ex-pression of GPX4.Compared with group G,the INT-777 administration group had a shorter consumption time for short-term neurobehavioral tests,lower scores,the cerebral infarction volume,brain water content,and brain ferrous ion content decreased,the brain tissue damage on the affected side was reduced,and there was insignificant loss of Nissl substance,larger neuronal mi-tochondrial volume,increased mitochondrial cristae,re-duced expression of TFR1,and increased expression of GPX4.Conclusions INT-777 agonist TGR5 has a protective effect against hypoxic-ischemic encephalopa-thy in neonatal rats,and its mechanism of action may be related to the inhibition of neuronal ferroptosis.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.
