Objective To observe the clinical efficacy of thumb-tack needling therapy combined with Oxycodone Hydrochloride Sustained-Release Tablets in treating patients with severe cancer pain caused by malignant tumors.Methods A total of 60 patients diagnosed with severe cancer pain who were admitted to the Traditional Chinese Medicine Department of Qingpu Branch,Zhongshan Hospital Affiliated to Fudan University between November 2023 and December 2024 were selected as study subjects.Patients were randomly divided into an observation group and a control group using a random number table,with 30 cases in each group.The control group received conventional western medicine pain management,while the observation group received additional thumb-tack needling therapy based on the control group's treatment.The treatment duration was 2 weeks.After treatment,clinical efficacy was evaluated by observing changes in European Quality of Life-5 Dimensions(EQ-5D)scores,Numerical Rating Scale(NRS)scores,Cancer Pain Self-Efficacy Scale(CPSS)scores,and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30)scores in both groups before and after treatment.Changes in serum levels of prostaglandin E2,endothelin-1,β-endorphin,and substance P were also compared.Safety and adverse reactions were assessed.Results(1)The total analgesic effective rate was 76.67％(23/30)in the observation group and 46.67％(14/30)in the control group.The total effective rate in the observation group was significantly higher than that in the control group,with a statistically significant difference(P＜0.05).(2)After treatment,serum levels of prostaglandin E2,endothelin-1,β-endorphin,and substance P were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(3)After treatment,EQ-5D scores,NRS scores,and CPSS scores were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(4)After treatment,EORTC QLQ-C30 scores were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(5)The incidence of adverse reactions was 53.33％(16/30)in the observation group and 83.33％(25/30)in the control group.The incidence of adverse reactions in the observation group was significantly lower than that in the control group,with a statistically significant difference(P＜0.05).Conclusion Thumb-tack needling therapy combined with Oxycodone Hydrochloride Sustained-Release Tablets significantly alleviates pain symptoms,improves health status and self-efficacy,and enhances the quality of life in patients with severe cancer pain caused by malignant tumors.

Objective To investigate the therapeutic effects of the newly developed phosphodiesterase 5 inhibitor,CPD1,on pathological myocardial hypertrophy induced by abdominal aortic constriction(AAC)in rats,and its impact on activation of the autophagy signaling pathway in myocardial tissue.Methods Male Sprague Dawley rats weighing 180～200 g were divided randomly into five groups:Control,Sham,model(AAC),CPD1 treatment(AAC-CPD1,5 mg/kg),and sildenafil treatment(AAC-Sif,20 mg/kg)groups.Rats in all groups except the Control group underwent blunt dissection of the abdominal aorta at the branch point of the left renal artery.Rats in the AAC and treatment groups also underwent constriction and ligation surgery,while rats in the Sham group underwent dissection without ligation.After 3 days of modeling,rats in the treatment groups received either CPD1 or sildenafil via gavage,while rats in the Control,Sham,and AAC groups received an equal volume of physiological saline by gavage,once daily for 8 weeks.Small-animal ultra-high-resolution echocardiography and left ventricular catheterization were employed to assess left heart function and the heart mass index,and expression levels of the hypertrophy indicator,atrial natriuretic peptide(ANP),the key autophagy pathway factor,p62,and LC3A/B in rat left heart tissue were evaluated by Western blot and reverse transcription-polymerase chain reaction.Results Abdominal aortic stenosis affected left heart function in rats,characterized by an increased cardiac mass index and significant enlargement of myocardial cell cross-sectional area.ANP expression levels in left heart tissue were significantly elevated(P＜0.05),while autophagy signaling activity was reduced,with notable accumulation of LC3Ⅰprotein and reduced conversion to LC3Ⅱ.Expression levels of p62 protein were significantly increased.CPD1 and sildenafil significantly improved left ventricular function in AAC rats,reduced cardiac hypertrophy,inhibited expression levels of ANP and p62 proteins(P＜0.05),activated autophagy signaling,and promoted the conversion of LC3Ⅰ to LC3Ⅱ.Notably,low-dose CPD1 treatment was equivalent to high-dose sildenafil.Conclusions CPD1 promotes the activation of the autophagy signaling pathway in left heart tissue,inhibits the expression of p62 and ANP,reduces the cross-sectional area of myocardial cells,and improves pathological myocardial hypertrophy and left heart function impairment caused by AAC.CPD1 also has the advantage of a lower effective dose compared with sildenafil,offering a new treatment option for pathological myocardial hypertrophy.

This study explores the diagnosis and treatment of needle knife therapy for ankylosing spondylitis (AS) at middle and advanced stage based on the theory of meridian tendons, from a holistic perspective and syndrome differentiation. The treatment strategy includes "harmonizing yin and yang" to address root causes and "tendons-based release" to harmonize qi and blood, with the "tendons nodule points" as the core acupoint selection criterion. Based on this approach, the study systematically elaborates on two needle knife methods for AS: "governor vessel bone-piercing technique" and "below-the-umbilicus release technique", covering indications, acupoint location, and procedures. Clinical case examples are provided to enrich needle knife therapy guided by the theory of meridian tendons, offering insights for clinical and research work on AS.

Background With the events reporting on odors in drinking water, odorous substances in water have become a hot topic in water quality analysis. Due to the low concentration of the odor threshold and the complexity of the odor components in water, it is difficult to make accurate qualitative and quantitative analysis. So it is necessary to develop a highly sensitive and accurate qualitative and quantitative analysis method. Objective To establish a method for simultaneous determination of four odorous substances, including dimethyl disulfide, dimethyl trisulfide, 2-methylisoborneol, and geosmin in water by purge and trap-gas chromatography-tandem mass spectrometry. Methods A certain amount of water sample was stored in the sample vial of a purge and trapinstrument. Through nitrogen purging, the odorous substances in water were purged out and enriched in the trap. Subsequently, the odorous substances were rapidly released at high temperatures after heating the trap, and then carried by carrier gas into gas chromatograph. After temperature programming, the substances were separated by an Agilent DB-624 capillary chromatographic column (30 m×0.25 mm, 1.4 μm) and determined by tandem mass spectrometry in multiple reaction monitoring modes, with internal standard method for quantification. The current project optimized purge time, sodium chloride concentration in water sample, desorption temperature, desorption time, and split ratio during the experimental process. Under the optimized experimental conditions, the standard curve, detection limit, and quantification limit were validated. Recovery tests with spiking concentrations of 5.0, 10.0, 30.0, 80.0 ng·L⁻¹ and precision tests were conducted on water samples. Finally, the established method was applied to detect odorous substances in source water, finished water, and pipeline water in Deqing County of Huzhou City. Result After the optimization, the purge time was 20 min, the desorption temperature was 280 ℃, the desorption time was 2 min, the split ratio was 10∶1, and no sodium chloride was added during the purge process. Under the optimized experimental conditions, the calibration curves for the four odorous substances showed an excellent linearity in the range of 1 to 100 ng·L⁻¹ (R>0.999), with 0.3 ng·L⁻¹ limit of detection and 1.0 ng·L⁻¹ limit of quantitation. The average recoveries were from 85.5% to 102.4% and relative standard deviations (RSD) from 1.6% to 5.2%. After applying this method to detect local source water, finished water, and pipeline water, it was found that the positive rates of 2-methylisoborneo, and geosmin were relatively high, while the positive rates of dimethyl disulfide and dimethyl trisulfide were relatively low. Only one sample of source water tested positive for dimethyl disulfide, and all samples were negative for dimethyl trisulfide. Conclusion Combined with the superiority of purge and trap and tandem mass spectrometry, the method has the advantages of easy to perform, strong anti-interference ability, good accuracy and precision, which meet the limit requirements of the four odorous substances in the expanded indices and reference indices of Hygienic standards for drinking water (GB 5749-2022). It also provides technical support for water quality assessment and analysis of odorous substances.

Aim To explore the application value of a predictive model constructed based on superb microvascu-lar imaging(SMI)blood flow grading indicators and serological indicators in evaluating the risk of carotid plaque shedding.Methods A total of 122 patients diagnosed with carotid plaque in Lishui Central Hospital from February 2019 to February 2021 were selected.SMI was used to observe the blood flow grading and plaque characteristics in carotid plaque,and baseline clinical data of the patients were recorded.All patients were followed up for a period of 2 years,with the occur-rence of transient ischemic attack(TIA)or acute ischemic stroke(AIS)as the endpoint event,and were divided into plaque shedding group and non-shedding group.Clinical data of the two groups were compared and analyzed,and multiple regression analysis was conducted to identify the relevant factors affecting carotid plaque shedding.According to the SMI ultrasound characteristics and serological indicators,R software was adopted to establish the nomogram model and evaluate effectiveness of the model.Results During the 2-year follow-up period,21 TIA cases and 14 AIS cases were found in the remaining 112 patients excluding 10 lost to follow up.The SMI blood flow grading,neutrophil to lymphocyte ratio(NLR),matrix metalloproteinase-9(MMP-9),and low density lipoprotein cholesterol(LDLC)levels in the plaque shedding group were higher than those in the non-shedding group,and the differences were statistically significant(P＜0.05).Multivariate Logistic regression analysis showed that SMI blood flow grade 3(OR=38.095),LDLC(OR=19.730),NLR(OR=34.525)and MMP-9(OR=1.225)were independent risk factors for carotid plaque shedding(P＜0.05).The R software established a column chart model and applied it to the ROC curve analysis.The AUC of the col-umn chart model in early prediction of plaque shedding was 0.917,with a sensitivity of 82.86％and a specificity of 90.91％.Conclusion The predictive model constructed by combining blood flow grading within carotid artery plaques and serological indicators through SMI can provide early warning of plaque shedding and guide clinical early intervention to reduce the risk of TIA and AIS.
