OBJECTIVE: To observe the clinical efficacy and safety of automatic pressure-controlled pressure cupping in patients with lumbar disc herniation, and compare it with traditional cupping. METHODS: A total of 100 patients diagnosed with lumbar disc herniation from January 2022 to August 2024 were selected and divided into two groups:the automatic pressure-controlled pressure cupping group (controlled pressure cupping group) and the traditional cupping group (control group), 50 cases in each group. In the controlled pressure cupping group, there were 18 males and 32 females, with an age of (51.98±12.69) years;in the control group, there were 16 males and 34 females, with an age of (51.32±12.05) years. The visual analogue scale(VAS), comfort score, and lumbar range of motion were observed before treatment and after the 1st, 3rd, and 7th treatments to evaluate the efficacy and safety. RESULTS: All patients completed the treatment intervention, with complete follow-up data collected. No adverse reactions or complications occurred during treatment and follow-up. After the 3rd treatment, the VAS score of the controlled pressure cupping group was (2.38±0.49), which was lower than that of the control group (2.94±0.68), with a statistically significant difference (P<0.001). In the controlled pressure cupping group, the VAS scores after the 1st, 3rd, and 7th treatments were significantly better than those before treatment (P=0.026);in the control group, the VAS scores after the 3rd and 7th treatments were better than those before treatment, but the difference was not statistically significant(P=0.182). Repeated-measures analysis of variance (ANOVA) on VAS scores at different time points in both groups showed that there were statistically significant differences in inter-group, time, and interaction effects (P<0.05). After the 1st treatment, in the controlled pressure cupping group, 0 patients felt comfortable, 42 patients (84%) felt mild discomfort, and 8 patients (16%) felt moderate discomfort;in the control group, 0 patients felt comfortable, 28 patients (56%) felt mild discomfort, and 22 patients(44%) felt moderate discomfort;the difference between the two groups was statistically significant(P=0.005). After the 3rd treatment, in the controlled pressure cupping group, 30 patients(60%) felt comfortable, 20 patients (40%) felt mild discomfort, and 0 patients felt moderate discomfort; in the control group, 9 patients (18%) felt comfortable, 41 patients (82%) felt mild discomfort, and 0 patients felt moderate discomfort;the difference between the two groups was statistically significant(P<0.001). There was no statistically significant difference in comfort between the two groups after the 7th treatment(P>0.001). There was no statistically significant difference in lumbar range of motion between the two groups before and after treatment(P>0.05);compared with before treatment, the lumbar range of motion of both groups after treatment was significantly improved, with statistically significant differences (P<0.001). CONCLUSION Automatic pressure-controlled pressure cupping can effectively relieve symptoms in patients with lumbar disc herniation, with excellent safety.

OBJECTIVE: To analyze the distribution characteristics of glucose-6-phosphate-dehydrogenase (G6PD) mutations and their enzyme activity in newborns patients with G6PD deficiency in Guilin region. METHODS: From July 2022 to July 2024, umbilical cord blood samples from 4 554 newborns in Guilin were analyzed for G6PD mutations using fluorescence PCR melting curve analysis. Enzyme activity was detected in 4 467 cases using the rate assay. RESULTS: Among 4 467 newborns who underwent G6PD activity testing, 162 newborns (3.63%) were identified as G6PD-deficient, including 142 males (6.04%) and 20 females (0.94%), the prevalence of G6PD deficiency was significantly higher in males than in females (P < 0.001). Genetic analysis of 4 554 newborns detected G6PD mutations in 410 cases (9%), including 171 males (7.13%) and 239 females (11.09%), with a significantly higher mutation detection rate in females than in males (P < 0.001). A total of nine single mutations and four compound heterozygous mutations were identified. The most common mutations were c.1388G>A (33.66%), c.1376G>T (23.66%) and c.95A>G (16.34%). Among newborns who underwent both enzyme activity and genetic mutation testing, males with G6PD mutations had significantly lower enzyme activity than that of females with G6PD mutations(P < 0.001). Specifically, among newborns carrying the mutations c.1388G>A, c.1376G>T, c.95A>G, c.1024C>T or c.871G>A, males consistently exhibited lower enzymatic activity than females with the same mutations (P < 0.001). Furthermore, in male G6PD-deficient newborns, the enzyme activity levels in those carrying c.1388G>A, c.1376G>T, c.95A>G, c.1024C>T, or c.871G>A were lower than those in both the control group and the c.519C>T group (P < 0.05). CONCLUSION This study provides a comprehensive profile of G6PD deficiency incidence and mutation spectrum in the Guilin region. By analyzing enzyme activity and genetic mutation results, this study provides insights into potential intervention strategies and personalized management approaches for the prevention and treatment of neonatal G6PD deficiency in the region.

A method for determination and targeted screening of diflorasone components in health products using ultra performance liquid chromatography-quadrupole time of flight mass spectrometry(UPLC-Q-TOF/MS)was established.Four representative diflorasone and esters(diflorasone,diflorasone diacetate,diflorasone-17-propionate,and diflorasone-21-propionate)were selected to optimize the pretreatment conditions,and 10 mL of extraction solvent dosage,15 min of extraction time and 5 g of salting-out agent as the optimal conditions were selected by response surface methodology.The results showed that the four analytes exhibited good linearity within the concentration range of 2.0?100 μg/L with the chromatographic peak area,and the correlation coefficients(R2)were all greater than 0.9990,while the results of recovery and relative standard deviation could satisfy the requirements of determination.The common characteristic ions of diflorasone and esters werem/z121 andm/z335,and their specific structures were obtained by analyzing the cleavage pathway based on the optimized determination conditions.A targeted screening method for other esters of diflorasone based on characteristic ions guidance strategy was established.This method had many advantages such as high efficiency,high sensitivity and good reproducibility,and could be used for targeted screening of diflorasone and esters in health products.The developed characteristic ion guided strategy could be employed to construct mass spectral databases for various glucocorticoids,enabling comprehensive targeted screening across a broad range of compounds.

A qualitative identification method for Salmonella using high-performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)with multiple reaction monitoring(MRM)mode was established.Eight characteristic peptides were selected,and their MRM parameters were optimized.Furthermore,the performance of this HPLC-MS/MS method in species identification was further evaluated.Experimental results demonstrated that this method exhibited high specificity,enabling accurate differentiation of Salmonella from conventional food-borne pathogens.In a milk matrix,the 50%limit of detection(LOD50)was determined to be 0.35 CFU/25 g.This method was successfully applied to qualitatively identify Salmonellain five artificially contaminated food samples.The method presented here,in contrast to traditional biochemical assays,offered both speed and specificity,providing a novel means for the rapid and accurate identification of Salmonella in food.It held significant implications for the surveillance,prevention,and control of food-borne diseases.

Objective:To explore the mechanism of Xiaojinwan in treating breast cancer bone metastases through cell experiments and bioinformatic analysis. Method:The inhibitory effect of Xiaojinwan on MCF-7 cell viability was detected by cell counting kit-8 （CCK-8） assay. The key components and targets responsible for Xiaojinwan in inhibiting breast cancer bone metastases were predicted by network pharmacology and molecular docking. The active components and targets of Xiaojinwan were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCSMP） and SwissTarget Prediction， and the breast cancer bone metastases-related targets from GeneCards and DisGeNET. The results were imported into STRING for constructing a protein-protein interaction （PPI） network， followed by Gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis using DAVID. A network of the active components of Xiaojinwan-breast cancer bone metastases-related targets-pathways was constructed using Cytoscape 3.7.2. AutoDock 4 was employed for molecular docking. The protein expression levels of matrix metallopmteinase-9 （MMP-9）， hypoxia-inducible factor 1α （HIF1A）， and androgen receptor （AR） were assayed by Western blot. Result:Xiaojinwan inhibited the viability of MCF-7 cells and acted on breast cancer bone metastases through such processes as redox and protein autophosphorylation. KEGG enrichment analysis showed that HIF-1， vascular endothelial growth factor （VEGF） and phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） pathways were involved. As verified by molecular docking， the active components such as eucalyptin stably bound to AR and MMP-9. Western blot indicated that Xiaojinwan dose-dependently inhibited the expression of MMP-9 and HIF1A proteins in MCF-7 cells. Conclusion:Xiaojinwan acts on AR and MMP-9 through HIF， VEGF and other related signaling pathways， thereby improving hypoxia in tumor microenvironment， inhibiting angiogenesis， and reducing cell invasion and viability.

ObjectiveThe present study was conducted to investigate the protective effect on cardiac function and potential mechanism of Compound Danshen Dripping Pills （CDDPs） on myocardial ischemia reperfusion in rats. MethodsThirty two male SD rats were underwent cardiac reperfusion following 45 minutes of left anterior descending coronary artery ligation， and randomly divided into 4 groups （n= 8 ）， rats in each group were given different doses of CDDPs （40，80，120 mg·kg^-1·d^-1 ）， or normal saline （control group） by gavage. Another 8 rats underwent similar procedure but without LAD ligation were set as sham group （were also given same volume of normal saline by gavage）. The treatment lasted for 4 weeks. Then echocardiography was conducted to evaluate the end-point cardiac function. HE and Masson’s trichrome staining were performed to observe the change of histomorphology and fibrosis. CD31/α-SMA immunofluorescence was implemented to investigate the endothelial to mesenchymal transition in cardiac microvessels. Western Blot was used to analyze the expression of α-SMA and CD31 in ventricular tissue of infarcted border zone. Data were analyzed by one-way ANOVA or Kruskal-Wallis H non-parametric test. ResultsCompared with normal saline group， treatment with different doses of CDDP could increase ejection fraction and fractional shortening significantly （P＜0.05 at least）， decrease left ventricular end-diastolic volume and the E/A ratio significantly （P＜0.05 at least）， reduce the cardiac collagen volume fraction （both P<0.05）， and suppress the expression of mesenchymal marker α-SMA in cardiac microvessels detected by immunofluorescent staining（P＜0.05 at least）， and decrease the expression of α-SMA and increase the expression of CD31 in ventricular tissue of infarcted border zone detected by Western blot. ConclusionTreatment with 40/80/120 mg·kg^-1·d^-1 doses of CDDPs for 4 weeks could improve cardiac function in rats underwent ischemia-reperfusion， this might be through reducing the occurrence of endothelial to mesenchymal transition in microvessels within heart tissue， and subsequently decreasing the cardiac fibrosis.

OBJECTIVE: To evaluate the efficacy and safety of Chinese medicine (CM) improving pregnancy outcomes after surgery for endometriosis-associated infertility. METHODS: A multicenter, randomized, double-blind placebo parallel controlled clinical trial was designed. A total of 202 patients who had laparoscopy for endometriosis-associated infertility with qi stagnation and blood stasis syndrome were included and randomly divided into the CM treatment group and placebo control group at a ratio of 1:1 using a central block randomization from May 2014 to September 2017, 101 patients in each group. The two groups received continuous intervention at 1-5 days after surgery, for 6 menstrual cycles. Before ovulation, the CM group was treated Huoxue Xiaoyi Granule (); after ovulation, Bushen Zhuyun Granule ( was involved. The control group was treated with placebo. Transvaginal ultrasonography was performed every menstrual cycle during the treatment, and female hormone levels in the follicular and luteal phases were measured during the 1st, 3rd and 6th menstrual cycles. The analysis was continued until pregnancy. The primary outcomes were clinical pregnancy rate and pregnancy outcome, and the secondary outcomes were follicular development and endometrial receptivity. Safety evaluations were performed before and after treatment. RESULTS: (1) Clinical pregnancy and live birth rates: the clinical pregnancy and live birth rates of the CM group were significantly higher than those of the placebo group [44.6% (45/101) vs. 29.7% (30/101), 34.7% (35/101) vs. 20.8% (21/101), both P<0.05]. (2) Follicle development: the incidence of dominant follicles, rate of cumulative cycle ovulation, and rate of cumulative cycle mature follicle ovulation were significantly higher in the CM group than those in the placebo group [93.8% (350/373) vs. 89.5% (341/381), 80.4% (275/342) vs. 69.1% (253/366), 65.8% (181/275) vs 56.1% (142/253), P<0.05 or P<0.01]). The incidence of cumulative cycle luteinized unruptured follicle syndrome was significantly lower in the CM group than in the placebo group [11.7% (40/342) vs. 17.8% (65/366), P<0.05). (3) Endometrial receptivity: after treatment, both endometrial types and endometrial blood flow types in the CM group were mainly types A and B, while those in the placebo group were mainly types B and C, with a significant difference between the two groups (both P<0.05). (4) Adverse events: the incidence of adverse events between the two groups was not significantly different (P>0.05). CONCLUSION Strategies for activating blood circulation-regulating Gan (Liver)-tonifying Shen (Kidney) sequential therapy can effectively improve the clinical pregnancy rate and live birth rate of endometriosis-associated infertility with qi stagnation and blood stasis after laparoscopy, improve follicular development, promote ovulation, improve endometrial receptivity, while being a safe treatment option.
