Objective:
To investigate the mechanism of Yishen Tongluo Formula in ameliorating renal pyroptosis in diabetic nephropathy mice by regulating the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-κB (NF-κB) signaling pathway.
Methods:
Sixty C57BL/6 male mice were randomly divided into control (10 mice) and intervention groups (50 mice) using random number table method. The diabetes nephropathy model was established by intraperitoneally injecting streptozotocin(50 mg/kg). After modeling, the intervention group was further divided into model, semaglutide (40 μg/kg), and high-, medium-, and low-dose Yishen Tongluo Formula groups (15.6, 7.8, and 3.9 g/kg, respectively) using random number table method. The high-, medium-, and low-dose Yishen Tongluo Formula groups were administered corresponding doses of medication by gavage, the semaglutide group received a subcutaneous injection of semaglutide injection, and the control group and model groups were administered distilled water by gavage for 12 consecutive weeks. Random blood glucose levels of mice in each group were monitored, and the 24-h urinary protein content was measured using biochemical method every 4 weeks; after treatment, the serum creatinine and urea nitrogen levels were measured using biochemical method. The weight of the kidneys was measured, and the renal index was calculated. Hematoxylin and eosin, periodic acid-Schiff, periodic Schiff-methenamine, and Masson staining were used to observe the pathological changes in renal tissue. An enzyme-linked immunosorbent assay was used to detect urinary β2-microglobulin (β2-MG), neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) levels. Western blotting and real-time fluorescence PCR were used to detect the relative protein and mRNA expression levels of nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3), Caspase-1, gasdermin D (GSDMD), interleukin-1β (IL-1β), and interleukin-18 (IL-18) in renal tissue. Immunohistochemistry was used to detect the proportion of protein staining area of the TLR4, MyD88, and NF-κB in renal tissue.
Results:
Compared with the control group, the random blood glucose, 24-h urinary protein, serum creatinine, urea nitrogen, and renal index of the model group increased, and the urine β2-MG, NGAL, and KIM-1 levels increased. The relative protein and mRNA expression levels of NLRP3, Caspase-1, GSDMD, IL-1β, and IL-18 in renal tissue increased, and the proportion of TLR4, MyD88, and NF-κB protein positive staining areas increased (P<0.05). Pathological changes such as glomerular hypertrophy were observed in the renal tissue of the model group. Compared with the model group, the Yishen Tongluo Formula high-dose group showed a decrease in random blood glucose after 12 weeks of treatment (P<0.05). The Yishen Tongluo Formula high- and medium-dose groups showed a decrease in 24-h urinary protein, creatinine, urea nitrogen, and renal index, as well as decreased β2-MG, NGAL, and KIM-1 levels. NLRP3, Caspase-1, GSDMD, IL-1 β, and IL-18 relative protein and mRNA expression levels were also reduced, and the proportion of TLR4, MyD88, and NF-κB protein positive staining areas was reduced (P<0.05). Pathological damage to renal tissue was ameliorated.
Conclusion
Yishen Tongluo Formula may exert protective renal effects by inhibiting renal pyroptosis and alleviating tubular interstitial injury in diabetic nephropathy mice by regulating the TLR4/MyD88/NF-κB signaling pathway.

Objective:To explore the effect of timely induction intervention on postpartum urination in primipara during vaginal delivery, so as to provide the evidence for preventing the occurrence of postpartum urinary retention and relieving the pain of primipara.Methods:This study adopted a randomized controlled trial design, and selected 400 cases of primipara who were hospitalized for vaginal delivery in the Obstetric Department of Dalian Women and Children's Medical Group Sports New Town Hospital from June 2021 to September 2022 as the study objects by convenience sampling method. They were divided into the intervention group and the control group with 200 cases each by random number table method, and the control group received routine postpartum care. Instruct active urination within 6 hours after delivery. The intervention received timely induction urination intervention. The general condition and bladder urine volume of the women in the intervention group were evaluated at 2, 4, 6 h after delivery, respectively, and personalized guidance was implemented, including the frequency of massage of the bottom of the uterus, the control of water intake, the selection of methods and timing of inducing urination, etc., and routine postpartum care was given when the women completed their first urination and had no complaints of discomfort. The first urination time, first urination volume, first bladder irritation during the first urination and the incidence of postpartum urinary retention in different periods were compared between the two groups.Results:The patients in the control group were (29.60 ± 3.20) years old, while the patients in the intervention group were (28.81 ± 3.42) years old. The first urination time in the intervention group was (6.89 ± 2.18) h, which was shorter than that in the control group (9.11 ± 3.86) h, and the difference was statistically significant ( t=-2.49, P<0.01). The first urination volume in the intervention group was (322.36 ± 120.15) ml, which was higher than that in the control group (262.93 ± 105.68) ml, and the difference was statistically significant ( t=3.39, P<0.05). The incidence of the first bladder irritation in the intervention group was 22.0%(44/200), which was lower than that in the control group 33.5%(67/200), and the difference was statistically significant ( χ2=6.60, P<0.05). The incidence of postpartum urinary retention within 24 h in the intervention group was 5.5%(11/200), which was lower than that in the control group 11.5%(23/200), and the difference was statistically significant ( χ2=4.63, P<0.05). The incidence of postpartum urinary retention within 1 week in the intervention group was 9.5%(19/200), which was lower than that in the control group 16.5%(33/200), and the difference was statistically significant ( χ2=4.33, P<0.05). There was no significant difference in the incidence of postpartum urinary retention within 24 to 72 h between the two groups ( P>0.05). Conclusions:Timely induction intervention can reduce the incidence of postpartum urinary retention, shorten the time of first urination, increase the volume of first urination and improve the comfort of first urination, which is worthy of clinical application.

Objective:To summarize the clinical features and postoperative efficacy of patients with oval window atresia accompanied by facial nerve aberration.Methods:The clinical data of patients with congenital middle ear malformation with facial nerve aberration admitted to our hospital from January 2015 to March 2023 were retrospectively analyzed. There were 97 cases (133 ears) in total. Among them, 39 patients (44 ears) had complete follow-up data, including 27 male patients and 12 females, aged 7-48 years old, with an average age of 17.8 years old. Of these, 14 cases (16 ears) were patients combined with facial nerve aberration, and 25 cases (28 ears) were without facial nerve aberration. The results of imaging examination, pure-tone audiometry, selection of surgical strategy, intraoperative findings and postoperative hearing improvement were summarized and analyzed. The malformations of malleus, incus, stapes, oval window and facial nerve were recorded. Prism 9 software was used to statistically analyze the mean bone conductance and air-bone gap of patients before and after surgery.Results:All the 14 patients (16 ears) with middle ear malformation accompanied by facial nerve aberration and oval window atresia showed poor hearing and no facial palsy since childhood. High resolution CT (HRCT) examination of temporal bone, pure tone audiometry and Gelle test were performed before surgery. The malformations of malleus, incus, stapes, oval window and facial nerve were recorded. Preoperative high-resolution CT (HRCT) examination of temporal bone found 12 ears with 4 or more deformities, accounting for 75.00%, in the group of patients with facial nerve malformation. The preoperative average bone conductive threshold was (15.3±10.4) dB and the average air-bone gap was (46.3±10.6) dB in pure-tone audiometry (0.5, 1, 2, 4kHz). According to the different degrees of facial nerve and ossicle malformation, we performed three different hearing reconstruction strategies for the 14 patients (16 ears) with facial nerve aberration and oval window atresia, including 7 ears of incus bypass artificial stape implantation, 7 ears of Malleostapedotomy (MS) and 2 ears of Malleus-cochlear-prothesis (MCP). After 3 months to 18 months of follow-up, all patients showed no facial paralysis. The postoperative mean bone conductive threshold was (15.7±7.9) dB and air-bone gap was (19.8±8.5) dB. There were significant differences in mean air-bone gap before and after operation ( t=7.766, P<0.05), and there was no significant difference between the mean bone conductive threshold before and after surgery ( t=0.225, P=0.824). There was no significant difference of mean reduction of air-bone gap between patients with and without facial nerve aberration ( t=1.412, P=0.165). There was no significant difference between the three hearing reconstruction strategies. There was no significant displacement of the Piston examined by U-HRCT. Conclusion:For patients of middle ear malformation whose facial nerve cover the oval window partially, incus bypass artificial stape implantation or Malleostapedotomy (MS) can be selected according to the specific condition of auditory ossis malformation, and for patients whose facial nerve completely covers the oval window area, Malleus-cochlear-prothesis (MCP) can be selected. Three types of stapes surgery are safe and reliable for patients with oval window atresia accompanied by facial nerve aberration. There was no significant difference in efficacy between them. Preoperative HRCT assessment of middle ear malformation is effective. There is no significant difference of surgical effect with or without facial nerve aberration. The U-HRCT can be used to evaluate the middle ear malformation before surgery and the Piston implantation status after surgery. Due to the risks of surgery, those who do not want to undergo surgery can choose artificial hearing AIDS, such as hearing aid, vibrating soundbridge, bone bridge or bone-anchored hearing aid.

By reviewing ancient materia medica, medical and prescription books, combined with modern literature, the textual research of Stephaniae Tetrandrae Radix has been conducted to verify the name, origin, producing area, harvesting and processing methods. Through textual research, the results show that the mainstream name of this herb recorded in the past dynasties is Fangji, which is also called Hanzhong Fangji because it is produced in Hanzhong city, and after the Tang dynasty, it was gradually divided into Hanfangji and Mufangji, and there is the saying that Han Zhushuiqi, Mu Zhufengqi. The names of Fenfangji and Guangfangji were first seen in the republic of China. In addition, Fenfangji was once distributed in Hankou, so it was also known as "Hanfangji", which is easily confused with the traditional Hanzhong Fangji for short. Based on the original research, it is concluded that Aristolochia heterophylla(Hanzhong Fangji)is the mainstream of Stephaniae Tetrandrae Radix used in the Qing dynasty and before, and the application history of Cocculus orbiculatus can be traced back to before the Tang dynasty. After the Ming dynasty, Stephania tetrandra gradually became another main origin, and in the Republic of China, A. fangchi was used as a medicine for Stephaniae Tetrandrae Radix, but in modern times it was banned because it contained aristolochic acid as a toxic ingredient, and S. tetrandra has become the mainstream legal origin. The traditional production area of Hanzhong Fangji is Hanzhong, Shaanxi province, while today the mainstream of S. tetrandra is manly produced in Jiangxi and other places. Based on the quality evaluation research, the quality of Hanzhong Fangji is better with the radial texture of section used as radial solution, yellow solid and fragrant. Fenfangji with solid quality, white inside, powdered enough, less fiber and radiating texture is better. From the harvesting and processing research, the root of Fangji is mostly harvested in spring and autumn, and the outer bark should be removed in some literature. Before the Ming dynasty, this herb was dried in the shade, and after the Ming dynasty, it was dried in the sun. The modern production processing of Fangji is to harvest it in autumn, wash it, remove the rough bark, dry it to half dry, cut it into sections, and then cut it longitudinally if it is large, and dry it. Based on the results, combined with current studies on the toxicity of aristolochic acid and influencing factors such as commercial circulation, it is suggested that S. tetrandra should be used as the origin of Fangji, the processed products are selected according to the prescription requirements, and those without specified requirements can be processed by referring to the raw products in the 2020 edition of Chinese Pharmacopoeia.

Through reviewing the ancient and modern literature, the name, origin, producing area, quality evaluation, harvesting and processing methods of Trichosanthis Fructus(TF) and Trichosanthis Radix(TR) in famous classical formulas were systematically sorted out following the chronological order. The results showed that there were many nicknames of TF and TR, and Gualou and Tianhuafen have become the mainstream names for its fruit and root, respectively. Both of them took Trichosanthes kirilowii as the mainstream base. TF and TR have been used as medicines in the Han dynasty, and since the North and South dynasties, Leigong Paozhilun had been clear that the effects of peels, seeds, stems, roots were different. TF was used as medicine with intact fruits, harvested after maturity from September to October, hung and dried in the shade, and its quality has been summarized in recent times as being best for those who are mature, large, thick and pliable peels, orange-yellow in color, and with sufficient sugary properties. In ancient times, the processing of TR was mostly crushed or shredded with the peels and seeds, or processing for pancakes and creams. TR was used as medicine with the roots, it is harvested from November to December, peeled and dried in the sun, and its quality was best when it was deep in the soil, large, white, powdery, firm and delicate with few muscles and veins, and it was considered to be toxic when it was born in briney land. Processing method of TR was to do powder into the medicine in the Tang dynasty, and gradually evolved into direct slicing use in the Ming and Qing dynasties. Since the modern era, the authentic producing areas of TF and TR were in the vicinity of Lingbao, Henan province, known as Anyang Huafen, and in modern times, there are well-known production areas such as Anguo, which produces Qihuafen, and Jinan, which produces Changqing Gualou. In the Song dynasty, there was a habit of substituting Trichosanthis Semen for the whole herb, which was later corrected by the materia medica in Ming dynasty. Based on the results, It is suggested that T. kirilowii be selected as the basal plant for the development of famous classical formulas involving TR and TF. In Qingjin Huatantang, Trichosanthis Semen is processed by stir-frying method, while TR and TF in other five formulas from the Catalogue of Ancient Famous Classical Formulas(The First Batch) were all used in raw form.

【Objective】 To study how blood donation intention among college students was influenced by publicity information (framework effect), individual characteristic (altruistic personality) and micro-system of the social ecological systems(organization trust) through the viewpoints of social psychology, sociology and behavioral economics, aiming at providing new strategies for donors recruitment in colleges. 【Methods】 A total of 1 225 questionnaires were distributed to four universities in Xiamen and Quanzhou, Fujian Province from June 2021 to December 2021, with blood donation publicity information included, to investigate the blood donation intention, altruistic personality, organization trust and demographic characteristics. 【Results】 A total of 99.18%(1 215/1 225)of the collected questionnaires were valid.The average score of blood donation intention was (76.40 ± 24.31) (the range of value was 0-100). Multiple linear regression showed that altruistic personality and organization trust were positively associated with donation intention (P<0.05). Altruistic personality and organization trust had a significant interaction; with the increase of organization trust, the correlation between altruistic personality and donation intention would decrease (P<0.05). In addition, the publicity information had significant frame effect on blood donation intention when other variables in the regression model were controlled (P<0.05). Compared to the negative framework, the positive framework can promote the donation intention better. 【Conclusion】 When recruiting potential blood donors among college students, positive image of blood centers is conductive to promote organization trust therefore promote donation intention.The effective use of framework effect to boost blood donation intention might improve the efficiency of donor recruitment to a certain extent.

Objective To investigate the impact of optical coherence tomography(OCT) imaging on physician decision-making during primary percutaneous coronary intervention(PCI) in patients with ST-segment elevation myocardial infarction (STEMI). Methods From January 2016 to May 2017, OCT was performed in 100 cases pre- and post- primary PCI. The pathogenesis of myocardial infarction was determined and immediate effect of PCI evaluated by OCT. Clinical outcome during a 12-months follow up was analyzed. Results The data from 17 patients were excluded for further study due to poor OCT images quality. The rates of plaque rupture, plaque erosion, calcification nodules, stent malapposition and coronary spasm were 65.1%(54/83), 26.5%(22/83), 3.6%(3/83), 2.4%(2/83) respectively among the remaining 83 patients with sufficient OCT quality images. of the overall rate of stent malposition, tissue prolapse and incomplete stent expansion was 21.7%(18/83). The incidence of edge dissection was 19.3%(16/83), and among them 2 patients required treatment with stent implantation. Among the 17 patients without stenting:coronary spasm were found in 2 cases, thrombus overload in 1 case after thrombus aspiration, plaque rupture in 7 cases , plaque erosion in 4 cases and stent malposition in 3 cases. One patient died in hospital for cardiogenic shock and one patient had subacute stent thrombosis . There were no major adverse cardiac events occurred in the remaining patients during the (11.0±4.0) months of follow-up. Conclusions OCT can identify nonoptimal stent deployment in approximately one-fourth of STEMI patients undergoing primary PCI, thus providing preliminary guidance to the physician for further mangement.
