Xiaoji Yinzi is one of the classic prescriptions for treating urinary diseases， originated from the Yan's Prescriptions to Aid the Living （Yan Shi Ji Sheng Fang） written by YAN Yonghe in the Song dynasty. Xiaoji Yinzi is composed of Rehmanniae Radix， Cirsii Herba， Talcum， Akebiae Caulis， Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， Angelicae Sinensis Radix， Gardeniae Fructus， and Glycyrrhizae Radix et Rhizoma and has the effects of cooling blood and stopping bleeding， draining water and relieving stranguria. The medical experts of later generations have inherited the original prescription recorded in the Yan's Prescriptions to Aid the Living， while dispute has emerged during the inheritance of this prescription. In this study， the method of bibliometrics was employed to review and analyze the ancient documents and modern clinical studies involving Xiaoji Yinzi. The results showed that Xiaoji Yinzi has two dosage forms： powder and decoction. According to the measurement system in the Song Dynasty， the modern doses of hers in Xiaoji Yinzi were transformed. In the prepration of Xiaoji Yinzi powder， 149.2 g of Rehmanniae Radix and 20.65 g each of Cirsii Herba， Talcum， Akebiae Caulis， stir-fried Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， wine-processed Angelicae Sinensis Radix， stir-fried Gardeniae Fructus， and stir-fried Glycyrrhizae Radix et Rhizoma are grounded into fine powder with the particle size of 4-10 meshes and a decocted with 450 mL water to reach a volume of 240 mL. After removal of the residue， the decoction was taken warm before meals， 3 times a day （i.e.， 7.77 g Rehmanniae Radix and 0.97 g each of the other herbs each time）. In the preparation of Xiaoji Yinzi decoction， 20.65 g each of the above 10 herbs are used， with stir-fried Typhae Pollen， wine-processed Angelica Sinensis Radix， stir-fired Gardeniae Fructus， stir-fired Glycyrrhizae Radix et Rhizoma， and raw materials of other herbs. Xiaoji Yinzi is specialized in treating hematuresis and blood stranguria due to heat accumulation in lower energizer， which causes injury of the blood collaterals of gallbladder and dysfunction of Qi transformation. In modern clinical practice， Xiaoji Yinzi is specifically used for treating urinary diseases and can be expanded to treat diseases of the cardiovascular system and other systems according to pathogenesis. The comprehensive research on the key information could provide a scientific reference for the future development of Xiaoji Yinzi.

Keratoconus is a blinding corneal disease characterized by central or paracentral corneal thinning and conical ectasia, and usually happens in adolescence. Currently, the etiology of keratoconus is unclear. Multiple studies have identified an association between genetics, eye rubbing, allergic diseases, ultraviolet exposure and keratoconus. Recently, several studies identified that sex hormones also played important roles in the pathogenesis of keratoconus. The disturbance of sex hormones may increase the risk of occurrence and progress of keratoconus. This review aims to summarize the pathophysiological effects of sex hormones on the cornea, clarify the effects of sex hormones on keratoconus and its related inflammatory or immune mechanisms, and explore the role of sex hormones in the early diagnosis and treatment of keratoconus, providing reference and help for clinical work.

In order to develop a more effective drug for dry eye disease, the preparation of lifitegrast eye drops was carried out, and the safety and efficacy of lifitegrast eye drops in vitro and in vivo were investigated. First the method for the determination of lifitegrast content was established, and then the composition and preparation process of the preparation were determined by literature review and single factor experiment. Finally, the safety of lifitegrast eye drops was evaluated by Draize eye irritation test and HE staining, and the therapeutic efficacy was evaluated by Schirmer test and ELISA test. The results showed that the final prescription of lifitegrast eye drops consisted of 5% lifitegrast, 0.4% sodium chloride, 0.3%−0.4% anhydrous disodium hydrogen phosphate, 0.3% sodium thiosulfate pentahydrate and 0.3% sodium hydroxide. The appearance of lifitegrast eye drops was transparent and slightly brownish yellow solution, the pH was7.75±0.05, the osmotic pressure was in the range of 200−330 mOsmol/kg and it had good stability at 60℃ for 3 months. There was no significant difference in irritation study compared with normal saline. Schirmer test showed that tear secretion was increased and the expression of inflammatory factors IL-6, IL-1β and TNF-α in tears were significantly decreased after treatment with lifitegrast eye drops and compared to the commercially available emulsion cyclosporine eye drops, it takes effect faster. The above results indicate that lifitegrast eye drops are simple to prepare and stable, which is a better choice for the rapid treatment of dry eye disease.

Objective To observe the incidence and prognosis of respiratory failure in patients after cardiac surgery,and the risk factors were analyzed.Methods A total of 559 patients who underwent cardiac surgery were enrolled in Tongji Hospital,Tongji Medical College of Huazhong University of Science and Technology from July 2020 to November 2023.Clinical data were extracted through the hospital information system(HIS).This included general data such as gender,age,body mass index(BMI),smoking history,alcohol history,comorbidities,and basic disease data like occurrence of respiratory tract infection in the past 1 month before surgery,preoperative use of antimicrobial drugs,ejection fraction,operation time,cardiopulmonary bypass time,intraoperative blood transfusion,nasogastric tube indwelling,nosocomial infection,secondary thoracotomy,preoperative white blood cell count(WBC),length of intensive care unit(ICU)stay,secondary intubation and tracheostomy,discharge diagnosis,and outcome.The patients were divided into two groups according to whether or not they had expiratory failure.The difference of the above data between the two groups was compared.Multivariate Logistic regression was used to analyze the risk factors of respiratory failure in patients after cardiac surgery,the prediction model was constructed based on the above risk factors,and the receiver operator characteristic curve(ROC curve)was drawn to analyze the predictive value of the prediction model for patients with respiratory failure.Results The incidence of respiratory failure in patients after cardiac surgery was 7.51%(42 cases).Multivariate Logistic regression analysis showed that intraoperative blood transfusion>2000 mL,nasogastric tube,and nosocomial infection were risk factors for respiratory failure in patients after cardiac surgery[odds ratio(OR)and 95%confidence interval(95%CI)were 4.136(1.794-9.535),3.162(1.454-6.878)and 3.488(1.262-9.638),all P<0.05].The ROC curve analysis showed that the prediction model had a certain predictive value for the occurrence of respiratory failure in patients after cardiac surgery[area under the curve(AUC)=0.738,95%CI was 0.658-0.818,P<0.001].The length of ICU stay of patients in the group with respiratory failure was significantly longer than that in the group without respiratory failure(hours:8.16±7.62 vs.4.52±3.95),the secondary intubation rate[80.95%(34/42)vs.0(0/517)]and the tracheostomy rate[88.10%(37/42)vs.0(0/517)]were significantly higher than those in the non-respiratory failure group,and the recovery/improvement rate was significantly lower than that in the non-respiratory failure group[59.52%(25/42)vs.90.13%(466/517)],the differences were statistically significant(all P<0.05).Conclusions Patients with intraoperative blood transfusion>2000 mL,nasogastric tube inserted,and nosocomial infection are the high-risk groups for respiratory failure after cardiac surgery.Medical staff should strengthen the identification of high-risk groups and actively take intervention measures to improve the prognosis of patients.

Objective:To investigate the effects and mechanism of Jinlong Bushen Mixture against lipid metabolism disorders induced by high-sugar and high-fat diet in rats with metabolic syndrome by combining network pharmacology and experimental validation.Methods:TCMSP and related literature were retrieved to obtain the active components and targets of wolfberry, golden cherry, longan meat, jujube, gynostemma, rosmarinus officinalis, and motherwort in Jinlong Bushen Mixture, and GeneCards online database was retrieved to obtain metabolic syndrome-related targets. Venny 2.1.0 was used to obtain the intersection targets of Jinlong Bushen Mixture and metabolic syndrome, and STRING online STRING online database was used to construct the PPI network of intersecting targets. Core targets in the top 50 degree values were screened using the Cyto NCA plugin in Cytoscape 3.9.0. The DAVID Bioinformatics Resources 6.8 online analysis platform was used for GO functional enrichment and KEGG pathway enrichment analysis. Metabolic syndrome rat model was established using high sugar, high salt, and high fat feed for 20 weeks. The successfully modeling rats were divided into model groups, positive control group and Jinlong Bushen Mixture group according to random number table, and a blank control group was also set up, with 8 rats in each group. Jinlong Bushen Mixture group was gavaged with Jinlong Bushen Mixture 1.8 ml/kg, a positive control group was gavaged with Metformin 90 mg/kg, and the blank and model groups were gavaged with an equal volume of saline, 1 time/d, for 4 weeks. The changes in body weight, abdominal circumference, and fasting blood glucose in rats were observed. The blood lipid level in rats was detected. The pathological changes of liver tissues were detected by HE staining. The levels of ATP, IL-1β, and IL-6 in liver tissues were determined by ELISA. The mRNA expression of liver kinase B1 (LKB1), AMPK, Akt1, carnitine palmitoyltransferase 1A (CPT1A), and downregulated lactate dehydrogenase A (LDH-A) in liver tissue were detected by qRT-PCR. Western blot was used to determine the expression of p-LKB1, LKB1, p-AMPK, AMPK, p-Akt1, and Akt1 in liver tissue were detected by Western blotting.Results:A total of 141 main active components, 841 active targets, 18 763 metabolic syndrome targets, and 820 drug-disease intersection targets of Jinlong Bushen Mixture were obtained. The KEGG pathway enrichment analysis yielded 173 entries, including mainly the PI3K-Akt, and HIF-1 signalling pathway. The experimental results showed that the weight, fasting blood glucose, and lipid levels of rats in the Jinlong Bushen mixture group decreased, and the disorder of liver glucose and lipid metabolism in rats improved; the levels of ATP, IL-1β and IL-6 decreased ( P<0.05); The mRNA expression of LKB1, AMPK, Akt1, and CPT1A in liver tissue increased ( P<0.05), while LDH-A mRNA expression decreased ( P<0.05). The p-LKB1/LKB1, p-AMPK/AMPK, and p-Akt1/Akt1 ratio increased ( P<0.05). Conclusion:Jinlong Bushen Mixture may restore lipid metabolism disorders in the metabolic syndrome through multiple targets and pathways. Its mechanism may exert pharmacological effects through the LKB1/AMPK/Akt signaling pathway.

Objective:To evaluate the effectiveness of correcting breast ptosis using the rotational filling of an inferolaterally pedicled tongue-shaped parenchymal flap via a double periareolar incision.Methods:A retrospective study was conducted on 34 female patients (68 breasts) with breast ptosis treated at the Department of Plastic Surgery at the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University from January 2016 to June 2023. The patients＇ ages ranged from 23 to 53 years, with an average of (37.4±7.9) years. All patients underwent correction of breast ptosis using an inferolaterally pedicled tongue-shaped parenchymal flap via a double periareolar incision. Pre-operative and post-operative measurements were taken to assess the corrective outcomes, including mammary base width (MBW), areola diameter (AD), nipple-to-nipple distance (NN), suprasternal notch-to-nipple distance (SSN-N), nipple-to-inframammary fold distance (N-IMF), and thoracic circumference at the nipple level (TN). Patients＇ satisfaction was assessed using the BREAST-questionnaire (BREAST-Q) module.Results:Postoperative first-stage wound healing was achieved in all 34 patients without complications such as hematoma, infection, or nipple necrosis. The follow-up period ranged from 6 to 60 months, with a median of 12 months. Early postoperative observations showed periareolar folds, which disappeared within 3 to 6 months in 31 cases, while mild periareolar folds, persisted for up to 12 months in 3 cases. Four patients reported reduced nipple sensation postoperatively. Measurements showed a statistically significant increase in TN and a reduction in NN, SSN-N, AD, N-IMF, and MBW compared to preoperative values (all P<0.001). BREAST-Q scores indicated significant improvements in satisfaction with breasts, psychosocial well-being and physical well-being, with preoperative scores of (21.6±8.9), (42.4±11.9) and (49.7±12.9) scores increasing to (82.3±8.5), (81.9±8.1) and (81.2±8.3) scores, respectively (all P<0.001). Conclusions:The double periareolar incision technique with rotational filling of an inferolaterally pedicled tongue-shaped glandular flap is a safe and effective method for correcting breast ptosis.
