ObjectiveBased on the concept of quality by design(QbD), the processing process of calcined Pyritum was optimized, and its X-ray diffraction(XRD) fingerprint was established. MethodsThe safety, effectiveness and quality controllability of calcined Pyritum were taken as the quality profile(QTPP), the color, hardness, metallic luster, phase composition, the contents of heavy metals and hazardous elements were taken as the critical quality attributes(CQAs), and the calcination temperature, calcination time, paving thickness and particle size were determined as the critical process parameters(CPPs). Differential thermal analysis, X-ray diffraction(XRD) and inductively coupled plasma mass spectrometry(ICP-MS) were used to analyze the correlation between the calcination temperature and CQAs of calcined Pyritum. Then, based on the criteria importance through intercriteria correlation(CRITIC)-entropy weight method, the optimal processing process of calcined Pyritum was optimized by orthogonal test. Powder XRD was used to analyze the phase of calcined Pyritum samples processed according to the best process, and the mean and median maps of calcined Pyritum were established by the superposition of geometric topological figures, and similarity evaluation and cluster analysis were carried out. ResultsThe results of single factor experiments showed that the physical phase of Pyritum changed from FeS2 to Fe7S8 during the process of temperature increase, the color gradually deepened from dark yellow, and the contents of heavy metals and harmful elements decreased. The optimized processing process of calcined Pyritum was as follows:calcination temperature at 750 ℃, calcination time of 2.5 h, paving thickness of 3 cm, particle size of 0.8-1.2 cm, vinegar quenching 1 time[Pyritum-vinegar(10∶3)]. After calcination, the internal structure of Pyritum was honeycomb-shaped, which was conducive to the dissolution of active ingredients. XRD fingerprints of 13 batches of calcined Pyritum characterized by 10 common peaks were established. The similarities of the relative peak intensities of the XRD fingerprints of the analyzed samples were>0.96, and it could effectively distinguish the raw products and unqualified products. ConclusionTemperature is the main factor affecting the quality of calcined Pyritum. After processing, the dissolution of the effective components in Pyritum increases, and the contents of heavy metals and harmful substances decrease, reflecting the function of processing to increase efficiency and reduce toxicity. The optimized processing process is stable and feasible, and the established XRD fingerprint can be used as one of the quality control standards of calcined Pyritum.

[Objective] To analyze the effects of different factors and red blood cell transfusion thresholds on the efficacy of neonatal red blood cell (RBC) transfusion, in order to provide more references for neonatal transfusions to better achieve rational and effective blood use. [Methods] A retrospective collection of data from 282 neonates who received RBC transfusions at our hospital from 2022 to 2023 was conducted, including birth weight, gestational age, number of blood transfusions, length of hospital stay, assisted ventilation during RBC transfusion, and laboratory test results before and after transfusion. SPSS software was used for statistical analysis to comprehensively analyze the impact of different factors on the efficacy of RBC transfusion in neonates. [Results] The results showed that the gestational age and weight of newborns at birth were negatively correlated with their length of hospital stay and the number of RBC transfusions during hospitalization. Newborns with younger gestational age and lower weight had longer hospital stays and more RBC transfusions during hospitalization. After administering RBCs according to the standard of 15 mL/kg, there was a statistically significant difference in the efficacy of RBC transfusion at different transfusion thresholds. In non-critical situations, RBC transfusions were ineffective when the pre-transfusion hemoglobin (Hb) level was >120 g/L. When the pre-transfusion Hb level was ≤70 g/L, RBC transfusions achieved higher efficacy in both critical and non-critical situations. [Conclusion] In critical situations, the group with pre-transfusion Hb values ≤ 70 g/L has the best RBC transfusion effect, while in non-critical situations, the group with pre-transfusion Hb levels between 81 and 90 g/L has the best RBC transfusion effect. Overall, the efficacy of RBC transfusion in non-critical situations is higher than that in critical situations.

ObjectiveTo investigate the effect and mechanism of Polygonatum neutral polysaccharides from sibiricum (PSP-NP) on colon injury in mice with chronic obstructive pulmonary disease (COPD). MethodsMale C57BL/6J mice were randomly divided into a control group, a COPD model group, and a PSP-NP group. The COPD model was established using smoke exposure combined with intranasal LPS administration. The PSP-NP group was simultaneously treated daily with 200 mg/kg of PSP-NP via intragastric gavage, while the other groups received an equal volume of saline. HE staining was used to observe the pathological changes in the colon. ELISA was employed to detect the levels of LPS in serum and the expressions of ZO-1, Occludin, IL-6, and TNF-α in colon tissue. UPLC-MS was used to detect the types and contents of bile acids in colonic content, and to screen for differential bile acids. Differential microbial flora were identified using 16S rRNA gene sequencing, and correlation analysis was conducted with differential bile acids. PSP-NP was combined with the differential bile acids cholic acid (CA), and deoxycholic acid (DCA) in vitro to analyze the binding capacity of PSP-NP for CA and DCA. PSP-NP was applied to NCM460 normal colonic epithelial cells cultured in CA and DCA. Cell migration ability was assessed using the scratch assay, and the mRNA expression levels of inflammatory cytokines TNF-α, IL-6, and NF-κB were measured by RT-qPCR. ResultsPSP-NP effectively improved colonic damage in COPD model mice, enhanced mechanical barrier function, alleviated inflammatory response, and regulated abnormal changes in colonic flora and bile acid metabolism. Correlation analysis further revealed that PSP-NP regulated colonic bile acid metabolism and reduced the redundancy of secondary bile acids by increasing the relative abundance of Bacteroidota, Verrucomicrobiota, Bacteroides, and Akkermansia, while decreasing the relative abundance of Lactobacillus and Bifidobacterium. Notably, in vitro binding assays demonstrated that PSP-NP bound to differential bile acids DCA and CA, with the strongest binding capacity for DCA at 58.2%. In cellular functional studies, DCA inhibited the migration ability of colonic epithelial cells NCM460 and significantly increased the relative mRNA expression levels of inflammatory factors TNF-α, IL-6, and NF-κB. Importantly, co-treatment with PSP-NP significantly ameliorated the impact of DCA on NCM460 cells. ConclusionsPSP-NP may significantly improve colonic damage in COPD model mice. The mechanism may involve the regulation of colonic bile acid metabolism and bile acid profiles through both microbial modulation and direct binding, thereby reducing the damage caused by secondary bile acids such as DCA to colonic epithelial cells.

ObjectiveThrough qualitatively and quantitatively analysis of the differences in chemical composition between the combined decoction and single decoction of Huaganjian and comparison of their core efficacy, to explore the rationality of the flexible clinical application of Huaganjian compound preparations and single-flavored dispensing granules. MethodsUltra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS) was used to qualitatively analyze the combined decoction and single decoction samples of Huaganjian, and meanwhile, the contents of four index components(geniposide, paeoniflorin, hesperidin and paeonol) were quantitatively analyzed by high performance liquid chromatography(HPLC). Nonalcoholic fatty liver disease(NAFLD) rat model induced by high-fat diet was applied to compare the efficacy of combined decoction and single decoction of Huaganjian. A total of 30 male SD rats were randomly divided into the control group, model group, lovastatin group(1.8 mg·kg-1), combined decoction group(1.26 g·kg-1) and single decoction group(1.18 g·kg-1). After successful modeling, lovastatin group, combined decoction group and single decoction group were given corresponding doses of drugs by intragastric administration every day, and the control group and model group were given equal amounts of normal saline by intragastric administration, after 4 weeks of administration, the serum and liver tissues were collected, and the contents of alanine aminotransferase(ALT), aspartate aminotransferase(AST), total cholesterol(TC), triglyceride(TG), low-density lipoprotein cholesterol(LDL-C) and high-density lipoprotein cholesterol(HDL-C) in serum of rats were detected, and the liver pathological examination was carried out by hematoxylin-eosin(HE) staining and oil red O staining, so as to compare differences of their efficacy. ResultsSeventy chemical components were initially identified and attributed from the lyophilized powder of the combined decoction and single decoction samples of Huaganjian, and there was no obvious difference in composition between the two. Further quantitative analysis showed that the contents of geniposide, paeoniflorin, hesperidin and paeonol in the combined decoction samples were significantly increased when compared with those of the single decoction samples(P<0.01). The pharmacodynamic results showed that compared with the model group, both the combined and single decoction groups of Huaganjian could improve the liver index of NAFLD rats, reduce the serum levels of AST, ALT, TC, TG and LDL-C, increase the serum level of HDL-C, and ameliorate the pathological changes of liver cell steatosis and fat accumulation. However, there was no significant difference in pharmacodynamic effects between the combined decoction group and the single decoction group. ConclusionThere is no significant difference between the combined decoction and single decoction of Huaganjian in terms of chemical composition, but the contents of the four index components show significantly difference. Both of them can significantly improve the fat accumulation and liver function in NAFLD rats. This study provides a reference basis for the rational clinical application and evaluation of famous classical formula compound preparations and single-flavored dispensing granules.

Objective To compare the long-term survival of elderly patients with esophageal squamous cell carcinoma (ESCC) treated with surgical versus non-surgical treatment. Methods A retrospective analysis was conducted on the clinical data of elderly patients aged ≥70 years with ESCC who underwent esophagectomy or radiotherapy/chemotherapy at Sichuan Cancer Hospital from January 2009 to September 2017. Patients were divided into a surgical group (S group) and a non-surgical group (NS group) according to the treatment method. The propensity score matching method was used to match the two groups of patients at a ratio of 1∶1, and the survival of the two groups before and after matching was analyzed. Results A total of 726 elderly patients with ESCC were included, including 552 males and 174 females, with 651 patients aged ≥70-80 years and 75 patients aged ≥80-90 years. There were 515 patients in the S group and 211 patients in the NS group. The median follow-up time was 60.8 months, and the median overall survival of the S group was 41.9 months [95%CI (35.2, 48.5)], while that of the NS group was only 24.0 months [95%CI (19.8, 28.3)]. The 1-, 3-, and 5-year overall survival rates of the S group were 84%, 54%, and 40%, respectively, while those of the NS group were 72%, 40%, and 30%, respectively [HR=0.689, 95%CI (0.559, 0.849), P<0.001]. After matching, 138 patients were included in each group, and there was no statistical difference in the overall survival between the two groups [HR=0.871, 95%CI (0.649, 1.167), P=0.352]. Conclusion Compared with conservative treatment, there is no significant difference in the long-term survival of elderly patients aged ≥70 years who undergo esophagectomy for ESCC. Neoadjuvant therapy combined with surgery is still an important choice to potentially improve the survival of elderly patients with ESCC.

ObjectiveTo explore the effect of Yishen Tongluo prescription on sperm DNA fragmentation index (DFI) and sperm mitochondrial membrane potential (MMP) in patients with asymptomatic idiopathic asthenospermia infertility. MethodsA total of 128 patients with asymptomatic idiopathic asthenospermia were randomly assigned to an experimental group (64 cases) and a control group (64 cases). The experimental group received Yishen Tongluo prescription, while the control group was treated with Wuzi Yanzongwan combined with L-carnitine oral solution. One treatment course lasted 12 weeks. Spouse pregnancy rate, sperm progressive motility (PR), total sperm motility (PR+NP), sperm function (sperm tail hypotonic swelling rate, sperm acrosin activity), sperm DFI, and sperm MMP were compared between the two groups before and after treatment. Adverse reactions were observed and recorded during the study, and clinical efficacy and safety were systematically evaluated. ResultsA total of 121 patients completed the study, including 61 in the experimental group and 60 in the control group. The spouse pregnancy rate in the experimental group was 14.75% (9/61), higher than that in the control group at 6.67% (4/60), though the difference was not statistically significant. Clinical efficacy in the experimental group was superior to that in the control group (P<0.05). Compared with the results before treatment, sperm PR, PR + NP, sperm tail hypotonic swelling rate, sperm acrosin activity, sperm DFI, and sperm MMP were significantly improved in both groups after treatment (P<0.05), with greater improvements in the experimental group (P<0.05). However, there was no significant change in sperm concentration in either group after treatment. During the study, no abnormal safety indicators or significant adverse reactions occurred in either group. ConclusionThe kidney-tonifying and collateral-dredging method shows good clinical efficacy in the treatment of asymptomatic idiopathic asthenospermia infertility. Yishen Tongluo prescription can improve sperm motility, increase spouse pregnancy rate, enhance sperm function, and demonstrates good safety. Its mechanism may be related to reducing sperm DFI and increasing sperm MMP.

Background::Breast cancer is ranked among the most prevalent malignancies in the Chinese female population. However, comprehensive reports detailing the latest epidemiological data and attributable disease burden have not been extensively documented.Methods::In 2018, high-quality cancer surveillance data were recorded in 700 population-based cancer registries in China. We extracted data on female breast cancers (International Classification of Diseases, Tenth Revision [ICD-10]: C50) and estimated the incidence and mortality in 2022 according to the baseline data and corresponding trends from 2010 to 2018. Pathological types were classified according to the ICD for Oncology, 3rd Edition codes. Disability-adjusted life years (DALYs) were calculated as the sum of the years of life lost (YLLs) and years lived with disability (YLDs).Results::In 2022, approximately 357,200 new female breast cancer cases and 75,000 deaths occurred in China, accounting for 15.59% and 7.94% of total new cancer cases and deaths, respectively. The age-standardized incidence rate (ASIR) was 33.04 per 100,000. When analyzed by pathological type, the ASIRs for papillary neoplasms, invasive breast carcinoma, rare and salivary gland-type tumors, and other types were 1.13, 29.79, 0.24, and 1.88 per 100,000, respectively. The age-standardized mortality rate (ASMR) was 6.10 per 100,000. A total of 2,628,000 DALYs were found to be attributable to female breast cancer in China, comprising 2,278,300 YLLs and 349,700 YLDs. The ASIR, ASMR, and age-standardized rate (ASR) for DALYs in urban areas were consistently higher than those in rural areas. We observed a four-fold increase in the ASIR and ASR for DALYs and an eight-fold increase in the ASMR among females over 55 years compared with those aged under 55 years.Conclusion::These data provide invaluable insights into the latest epidemiology of female breast cancer in China and highlight the urgency for disease prevention and control strategy formulation.
