ObjectiveTo investigate whether Shenmai injection （SMI） improves cisplatin resistance in non-small cell lung cancer （NSCLC） by modulating lipid metabolism and inducing ferroptosis. MethodsHuman lung adenocarcinoma cisplatin-resistant A549/DDP cells were divided into the following groups： Blank group， cisplatin group （23.3 μmol·L^-1 cisplatin）， SMI group （20 g·L^-1 SMI）， cisplatin combined with SMI group （23.3 μmol·L^-1 cisplatin + 20 g·L^-1 SMI）， cisplatin combined with ferroptosis inhibitor/inducer Ferrostatin-1/Erastin group （23.3 μmol·L^-1 cisplatin + 10 μmol·L^-1 Ferrostatin-1/5 μmol·L^-1 Erastin）， and cisplatin combined with SMI and Ferrostatin-1/Erastin group （23.3 μmol·L^-1 cisplatin + 20 g·L^-1 SMI + 10 μmol·L^-1 Ferrostatin-1/5 μmol·L^-1 Erastin）. Network pharmacology， transcriptomics and metabolomics， Cell Counting Kit-8 （CCK-8） assay， transmission electron microscopy （TEM）， colorimetric assays， and Western blot analysis were employed to evaluate the effects of these treatments on A549/DDP cell viability， lipid droplet formation， lipid metabolite levels， mitochondrial function， lipid peroxidation， glutathione （GSH） content， total and ferrous iron content， and effects on ferroptiosis and autophagy related protein expression levels. ResultsSMI improved cisplatin resistance in NSCLC mainly by targeting lipid metabolism-related pathways in A549/DDP cells， affecting tumor cell lipid metabolism via autophagy， ferroptosis， and glycerophospholipid metabolism pathways. Compared with the cisplatin group， the cisplatin combined with SMI group showed significantly decreased cell viability （P<0.01）， increased lipid droplet accumulation （P<0.01）， and reduced mitochondrial maximal respiration， basal respiration， mitochondrial membrane potential， GSH content， total iron， and ferrous iron （all P<0.01）. Mitochondrial reactive oxygen species （ROS） was significantly elevated（P<0.01）， and lipid peroxidation levels were significantly increased. Protein expression analysis showed significant downregulation of solute carrier family 7 member 11 （SLC7A11） and p62 （P<0.05，P<0.01） and upregulation of ferritin heavy chain （FTH） and microtubule-associated protein 1 light chain 3Ⅱ （LC3Ⅱ） （P<0.05，P<0.01）. Compared with the cisplatin combined with SMI group， addition of Ferrostatin-1 significantly increased cell viability （P<0.05）， decreased mitochondrial ROS levels （P<0.05）， alleviated mitochondrial shrinkage， and reduced lipid peroxidation. Conversely， addition of Erastin further decreased cell viability （P<0.01）. ConclusionSMI improves cisplatin resistance in NSCLC by inducing oxidative stress， which may trigger ferroptosis through upregulation of lipophagy.

OBJECTIVE To explore the improvement effect and mechanism of salidroside on radiation-induced parotid gland injury in rats. METHODS Rats were randomly assigned into normal group， radiation group， salidroside low-dose （salidroside-L， 50 mg/kg） group， salidroside high-dose （salidroside-H， 100 mg/kg） group， and salidroside-H+inhibitor （100 mg/kg salidroside+0.1 µmol/kg H-89） group， with 10 rats in each group. Except for the normal group， rats in the other groups were subjected to radiation exposure to establish a model of radiation-induced parotid gland injury. Rats in each group were intraperitoneally injected with the corresponding drug or normal saline， once a day， for 40 consecutive days. After the last administration， the levels of reactive oxygen species （ROS）， cyclic adenosine monophosphate （cAMP）， superoxide dismutase （SOD）， and amylase in serum were detected； the pathological changes of parotid gland tissue were observed； the apoptosis rate of parotid gland tissue cells， the expression levels of B-cell lymphoma-2 （Bcl-2） and its associated X protein （Bax）， mRNA expression levels of interleukin-6 （IL- 6） and tumor necrosis factor-α （TNF-α）， the protein expression levels of type Ⅲ collagen （Col Ⅲ）， vasoactive intestinal peptide （VIP）， and the phosphorylation level of protein kinase A （PKA） in parotid gland tissue were determined. RESULTS Compared with normal group， the levels of ROS， amylase， apoptosis rate， Bax expression level， mRNA expression levels of IL-6 and TNF- α， and protein expression level of Col Ⅲ in the radiation group were significantly increased， while the levels of cAMP， SOD， Bcl-2 expression level， VIP protein expression level and PKA phosphorylation level were significantly decreased （P＜0.05）. Compared with radiation group， the above indicators in the salidroside-L group and salidroside-H group were significantly improved （P＜0.05）， and the improvement in the salidroside-H group was more significant （P＜0.05）； inhibitor H-89 significantly reversed the changes in the above indicators of the salidroside-H group （P＜0.05）. CONCLUSIONS Salidroside can effectively alleviate radiation-induced parotid gland injury in rats， and its mechanism may be related to the activation of the VIP-cAMP pathway.

The occurrence and development of laryngopharyngeal reflux(LPR)are closely related to the changes in the qi movement of the spleen,stomach,liver and lungs.The authors believed that"earth stagnation and wood depression"is the key to the onset of LPR.Based on this,the disease could be treated in three stages.In the early stage,the main symptoms are spleen clearing but not rising,difficulty in reducing gastric turbidity and abnormal rise and fall.Treatment should focus on regulating the spleen and stomach,promoting clearing and reducing turbidity,and commonly using modified Liujunzi Decoction;at the beginning of the middle stage,the main symptoms are earth stagnation,stagnation of qi and reflux of the throat.The treatment is suitable for using herbs clearing wood and promoting earth,regulating qi movement,and commonly using Sini Powder combined with modified Banxia Houpo Decoction or Chaihu Shugan Powder;at the end of the middle stage,the main treatment methods are wood stagnation turning into fire,horizontal rebellion invading the earth and upper inflammation punishing the metal.The treatment is suitable for using herbs acid in flavour for dispersing and herbs bitter in flavour foe descending,clearing the liver and stomach,and commonly using modified Banxia Xiexin Decoction and Zuojin Pills;in the later stage,the main symptoms are spleen and stomach deficiency,failure of earth to produce gold and failure of gold to break through without making a sound.The treatment is suitable for using herbs cultivating earth to produce gold,nourishing the throat and benefiting the throat,and commonly using modified Maimendong Decoction or Shenling Baizhu Powder,in order to provide theoretical basis for the treatment of LPR with TCM,broaden the thinking of diagnosis and treatment,and better improve clinical efficacy.

Objective To develop a quality evaluation indicator system for"Internet+indwelling tubes home nursing services"for a standardised evaluation process.Methods Based on the structure-process-outcome(SPO)model,a quality assessment indicator system for"Internet+indwelling tubes home nursing services"was developed.This system was refined via a comprehensive literature review,semi-structured interviews,clinical expertise,and a two-round Delphi consultation involving 20 experts from clinical nursing,nursing management,human resource management,public health and information technology.Results The effective recovery rate from both rounds of Delphi consultation was 100.00%.The authority coefficients for two-rounds of expert consultation were both at 0.785.Kendall's W coefficients for secondary indicators were 0.201 and 0.280,and 0.214 and 0.226 for tertiary indicators,all were statistically significant(P<0.05).After 2 rounds of expert consultation,the system demonstrated strong reliability:mean importance weights for all indicators exceeded 4.0,coefficients of variation were below 0.2,and full score rates included or surpassed 20%.The finalised quality evaluation indicator system for"Internet+indwelling tubes home nursing services"included 3 primary indicators(allocation of pipeline nursing service resources,implementation of pipeline nursing service resources,and feedback on the effectiveness of pipeline nursing service resources),12 secondary indicators,and 70 tertiary indicators.Conclusion The quality evaluation indicator system for"Internet+indwelling tubes home nursing services"developed in this study is scientifically reliable,practical and applicable for evaluation of the quality of"Internet+"pipeline home nursing services.

Objective To investigate the therapeutic effects of combined magnetic and electrical stimulation with an"intelligent exercise prescription"and novel matrix radiofrequency therapy in patients with pelvic organ prolapse(POP).Methods A total of 158 patients with POP who received treatment at the Gynecological Pelvic Floor Rehabilitation Center of the Eighth Affiliated Hospital of Southern Medical University between October 2022 and July 2025 were retrospectively enrolled and divided into an observation group(n=64)and a control group(n=94)based on their treatment plans.The control group underwent magnetic and electrical stimulation combined with an"intelligent exercise prescription"regimen.Specifically,patients received 10 sessions of electrical stimulation,5 sessions of magnetic stimulation,and performed 15～20 minutes of daily home exercise training guided by the"intelligent exercise prescription."The observation group received,in addition to the aforementioned treatments,four sessions of novel matrix radiofrequency therapy.Changes in the muscle strength grades of type Ⅰ and type Ⅱ pelvic floor muscles,Glazer surface electromyography(EMG)values,and POP-Q staging were compared between the two groups before and after treatment.Results After treatment,both groups demonstrated significant improvements in type Ⅰ and type Ⅱ muscle fiber strength compared to baseline(all P<0.05),with the observation group showing greater improvement in type Ⅰ muscle fiber strength than the control group(P<0.05).The muscle potential values of the observation group during rapid contraction,tense contraction,and endurance contraction stages were markedly increased compared to pre-treatment levels.Moreover,the muscle potential values during the pre-resting stage were significantly reduced after treatment(P<0.05).In the observation group,POP-Q grades of the anterior vaginal wall,uterus,and posterior vaginal wall were all significantly lower post-treatment than pre-treatment(all P<0.05).However,no statistically significant differences were observed between the observation group and the control group in these parameters(P>0.05).Both groups exhibited relatively high compliance rates(both≥75.0%),with no significant difference between them(P>0.05).The treatment cost for the observation group was significantly higher than that for the control group(P<0.05).Conclusions The combination of magneto-electrical stimulation,an"intelligent exercise prescription,"and novel matrix radiofrequency therapy can significantly improve pelvic floor muscle strength and muscle potential values in the short term,compared to pre-treatment levels.This integrated approach also effectively alleviates the prolapse of the anterior vaginal wall,uterus,and posterior vaginal wall.Furthermore,the combination of magnetic and electrical stimulation,"intelligent exercise prescription,"and matrix radiofrequency therapy demonstrates superior efficacy in enhancing type Ⅰ pelvic floor muscle fiber strength when compared to the combination of magnetic and electrical stimulation with"intelligent exercise prescription"alone.However,this treatment protocol entails a relatively high economic burden,and its clinical application should be carefully evaluated in consideration of patients'functional needs and financial conditions.

Objective:To assess the efficacy and safety of Gongxuening Capsules in reducing post-abortion bleeding following artificial abortion.Methods:A multicenter, randomized, double-blind study was conducted. From May 31, 2022 to March 31, 2023, 484 women who underwent vacuum aspiration abortion for early intrauterine pregnancy were enrolled in 11 centers and randomly assigned to control group and the study group at a 1∶1 ratio using a center-block randomization method. Control group were administered a placebo of Gongxuening Capsules for 9 d, while the study group received the actual Gongxuening Capsules for the same duration. The outcomes measured included vaginal bleeding volume, duration of vaginal bleeding, endometrial thickness, time to menstrual recovery, and complications.Results:1) A total of 484 subjects were enrolled, and 472 completed the study. Totally 450 subjects were included in the efficacy analysis set, with 224 in control group and 226 in the study group; 468 subjects were included in the safety analysis set, with 236 in control group and 232 in the study group. The baseline characteristics of the two groups were comparable (all P>0.05). 2) The vaginal bleeding volume was lower in the study group [(13.30±12.14) mL] than in control group [(19.00±17.67) mL, P<0.001]. The proportion of subjects in the study group with bleeding days less than 4 d [29.65% (67/226)] was higher than that in control group [19.20% (43/224), P=0.010]. 3) No significant differences were observed between the two groups in terms of time to menstrual recovery and endometrial thickness (all P>0.05). 4) In the study group, 3 subjects experienced non-therapeutic-related complications, while 11 subjects in control group. The incidence of complications was lower in the study group [1.29% (3/232)] than in control group [4.66% (11/236), P=0.033]. Conclusion:The administration of Gongxuening Capsules to women following artificial abortion significantly reduced vaginal bleeding volume and was associated with good safety, with the treatment being well-tolerated by the subjects.

Objective To investigate the prognostic value of thrombin-antithrombin III complex(TAT),plasmin-α2-plasmin inhibitor complex(PIC),thrombomodulin(TM)and tissue plasminogen activator-inhibitor complex(t-PAIC)in patients with myelodysplastic syndrome(MDS).Methods Selected 88 primary MDS patients diagnosed at the 521 Hospital of Ordnance Industry from January 2018 to January 2021.Plasma levels of TAT,PIC,TM,t-PAIC,fibrin degradation products(FDP)and D-dimer(D-D)were measured.A multivariate approach was used to analyze the association between overall survival(OS)and the levels of each coagulation marker.Coagulation markers significantly associated with OS were used to construct a coagulation prognostic scoring system.Based on the median coagulation marker score,MDS patients were divided into high and low score groups.Kaplan-Meier analysis was used to plot survival curves.Results TAT(OR=1.667),PIC(OR=0.734),TM(OR=1.294)and t-PAIC(OR=1.523)were independent factors influencing OS in MDS patients(Wald χ2=0.671～10.751,all P<0.05).The β-values were integrated as statistical weights to construct a coagulation marker score,calculated as follows:[TAT]×0.502-[PIC]×1.013+[TM]×0.181+[t-PAIC]×0.381.The OS(median 14.6 months)and leukemia free survival(LFS)(median 10.3 months)of patients in the high coagulation marker score group were significantly lower than those in the low score group(33.6 months,35.2 months)(Log rank=20.57,26.84,all P<0.001).Subgroup analysis indicated that in both the low-risk IPSS-R subgroup(very low,low,and intermediate risk)and the high-risk IPSS-R subgroup(high and very high risk),the OS(Log rank=9.12,4.30)and LFS(Log rank=4.54,8.51)of the high coagulation marker score group were lower than those of the low score group(all P<0.05).Bivariate analysis showed a moderate correlation between the coagulation marker score and Revise International Prognostic Scoring System(IPSS-R)(PCC=0.536,P<0.001).Multivariate analysis indicated that IPSS-R and high coagulation marker scores were independent risk factors for OS and LFS in MDS patients(P<0.05).Conclusion The coagulation marker score,based on TAT,PIC,TM and t-PAIC,can serve as an independent prognostic factor for OS and LFS in MDS patients.

Objective:To explore the treatment methods and prognosis of pregnancy-related uterine arteriovenous malformation (UAVM).Methods:A retrospective analysis was conducted on clinical data from 81 patients with UAVM treated at Peking Union Medical College Hospital between March 2019 and March 2024. Clinical manifestations, diagnostic approaches, treatment strategies and prognosis were evaluated.Results:(1) General Information: the age of patients with UAVM was (32.7±4.6) years, with median gravidity and parity of 1 (quartile range: 1, 2) and 0 (0, 1), respectively. Pregnancy termination methods included surgical abortion or curettage in 46 cases (57%, 46/81), medical induction in 17 cases (21%, 17/81), spontaneous abortion in 16 cases (20%, 16/81), vaginal delivery in 1 case (1%, 1/81), and laparoscopic pregnancy tissue removal in 1 case (1%, 1/81). (2) Clinical manifestations: clinical presentations comprised vaginal bleeding in 59 cases [73%, 59/81; median blood loss: 740 ml (440, 1 360 ml)], massive hemorrhage in 9 cases (11%, 9/81, and bleeding combined with lower abdominal pain in 8 cases (10%, 8/81). Ultrasonography revealed intrauterine masses in 65 cases [80%, 65/81; median size: 2.5 cm (1.8, 4.2 cm)]. Elevated serum human chorionic gonadotrophin-β subunit (β-hCG) levels were observed in in 55 cases [85%, 55/65; median: 62.6 U/L (14.9, 300.1 U/L)]. The median time to UAVM diagnosis via ultrasound was 30.0 days (16.0, 52.0 days) after pregnancy termination, with median peak systolic velocity (PSV) and resistance index of 59.8 cm/s (45.0, 79.6 cm/s) and 0.39 (0.36, 0.43), respectively. (3) Treatment and prognosis: treatment modalities included expectant management in 49 cases (36%, 29/81), medication in 13 cases (16%, 13/81), lesion resection in 31 cases (38%, 31/81), and uterine artery angiography in 8 cases (10%, 8/81; 5 confirmed as arteriovenous fistula). The median time of PSV returning to normal after treatment was 53.8 days (36.0, 93.4 days). The average time for β-hCG returning to normal was (60.4±20.4) days. The median return time of menses was 59.0 days (43.0, 75.4 days).Conclusions:Pregnancy-related UAVM carries a high risk of life-threatening hemorrhage, necessitating management in centers equipped for emergency uterine artery embolization. Informed consent must emphasize disease progression risks and prognosis. Treatment stratification should integrate clinical parameters and imaging features.

The incidence rate of allergic rhinitis(AR)is high and difficult to cure,which seriously affects the quality of life of patients.The theory of"deficient qi inducing stagnation"is highly consistent with the occurrence and development of this disease.This article believed that the"deficient qi"state of the deficiency of the lungs,spleen and kidney was the fundamental factor of the onset of AR,and the external pathogenic factors,cold,dampness and endogenous phlegm,stasis and turbidity caused by"deficient qi"were the inducing and aggravating factors of AR.It proposed to cultivate the earth to produce gold,gold and water to"replenish the deficient qi",to dispel the wind,to dissipate cold and dampness,to dispel phlegm and dampness,and to reducing stasis and promoting circulation,and to use the two-way regulation of strengthening the healthy qi and dispelling the pathogens,so that the healthy qi could be filled and the pathogen stagnation could be dispelled,in order to provide ideas for the TCM treatment of this disease.
