Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.

Testicular radiation injury is a structural and functional abnormality of the testes caused directly or indirectly by radiation, which disrupts spermatogenesis and compromises male fertility. The development of effective preventive and therapeutic interventions is essential because of the high prevalence of this condition in clinical settings and its profound effect on patients′ reproductive health and overall well-being. The concept of "the struggle between vital qi and pathogen" is first seen in the Treatise on Cold Pathogenic Diseases. It denotes the dynamic struggle between vital and pathogenic qi. The occurrence, development, and sequelae of all diseases reflect this ongoing conflict. In this context, this study defines the "vital qi" of the testis as its capacity to generate and preserve the essence of reproduction and to resist damage. The pathogenic qi associated with testicular radiation injury is categorized into two types: ionizing poison and retaining evil. The pathogenesis of testicular radiation damage is delineated into three stages by integrating the characteristics of vital and pathogenic qi: the injury, adhesion, and recovery phases. Based on the theoretical framework advanced by this study, the therapeutic approach for testicular radiation injury should adhere to the fundamental principle of strengthening vital qi and eliminating pathogenic factors. Although the primary focus of treatment should be on strengthening vital qi, it should also be complemented by strategies to eliminate pathogenic influences. This paper aims to provide a novel perspective and strategic approach to the traditional Chinese medicine diagnosis, prevention, and treatment of testicular radiation injury. By elucidating the process of testicular radiation injury and its corresponding treatment principles, it seeks to offer valuable insights for clinical practice.

Objective To explore the promoting effect of long-term administration of nicotiflorin on the recovery of neurological function in rats with cerebral ischemia-reperfusion injury （CIRI）. Methods The CIRI model was established and nicotiflorin was injected intraperitoneally after 1 hour of obstruction for 8 weeks. Tail suspension deflection experiment, balance beam experiment and water maze test were performed in the 2nd, 4th and 8th weeks. After 8 weeks, TTC staining was used to observe the volume of infarct atrophy, transcriptome sequencing was employed to screen differential expressed genes （DEGs） and highly enriched pathways were analyzed, Western-bloting and Elisa were used to assess proteins expression related to the pyroptosis pathway and inflammatory cytokines IL-1β and IL-18. Results By long-term administration of nicotiflorin, the contralateral deflection rate was significantly reduced and beam experiment score of CIRI rats was balanced, the number of crossing the platform in water maze test was increased （P<0.05）, the volume of cerebral infarction atrophy was decreased （P<0.01）, which significantly promoted the recovery of neurological function in rats. Transcriptome sequencing found that the expression of genes in the pyroptosis-related signaling pathways in the brain tissue of rats in the nicotiflorin group was significantly down-regulated （P<0.05）. Western-blot and Elisa experiments showed that nicotiflorin reduced the expression levels of Caspase-1 and GSDMD-N and other pyroptosis-related proteins, and at the same time, the release of inflammatory factors IL-1β and IL-18 was significantly reduced （P<0.05）, indicating that nicotiflorin could inhibit the inflammatory process of pyroptosis. Conclusion Nicotiflorin exhibited a significant long-term promotion effect on the recovery of neurological function in CIRI rats, which potentially attributed from its ability to inhibit pyroptosis.

Dexmedetomidine,which is an α2 adrenergic receptor agonist with sedative,analgesic,anxiolytic and anti-sympathetic effects,has become a widely used drug in clinical anesthesia and intensive care unit(ICU).Compared with other drugs in the department of anesthesiology,dexmedetomidine has no obvious respiratory depression and no obvious hemodynamic changes,and can significantly reduce the dosage of sedative and analgesic drugs when combined with other anesthetics.In clinical applications,dexmedetomidine has been found to induce a sedative response that is associated with rapid arousal.Dexmedetomidine is traditionally thought to act through α2 adrenergic receptors to lower blood pressure,dilate blood vessels and lower heart rate,but it is unclear how it affects neural circuits in the brain.In recent years,there has been an increasing number of studies on the mechanism of action of dexmedetomidine,which has confirmed that the ventrolateral preoptic nucleus(VLPO),locus coeruleus(LC)and ventral tegmental area(VTA)of the hypothalamus are involved in the sedation mediated by dexmedetomidine,the dorsal root ganglion(DRG)and superior cervical ganglion(SCG)are involved in dexmedetomidine-mediated analgesia,and the hypothalamic preoptic area(PO)and hypothalamic paraventricular nucleus(PVN)are involved in the changes in body temperature and water-electrolyte balance mediated by dexmedetomidine,providing a new direction for understanding the mechanism of dexmedetomidine in the central nervous system.

The pricing and reimbursement of orphan drugs are related to the accessibility of patients,and are of great significance to the prevention and guarantee of rare diseases.European countries have formed special standards and paths for health technology evaluation,and established special payment funds and diversified risk-sharing agreements,which have effectively improved the accessibility of orphan drugs.Based on this,it selected typical European countries to compare the orphan drug pricing and reimbursement methods.Then,it put forward some suggestions"building orphan drug health technology evaluation accelerated program,exploring the health of orphan drug classification security mechanism,and attaining supply incentives and development incentives through orphan drug pricing and adjustment",to optimize the basis for the orphan drug market access mechanism to provide reference.

Objective To understand the HIV/AIDS burden and the disease burden attributed to various risk factors in four countries with different socio-demographic index (SDI) (China, United States, Russia, and Afghanistan) from 1990 to 2019, and to predict the HIV/AIDS attributable disease burden from 2020 to 2029. Methods The 2019 Global Burden of Disease Study data was used to describe and compare the incidence, prevalence, death, and DALYs of HIV/AIDS in the four countries. The standardized DALYs attributed to various risk factors in different age groups of HIV/AIDS in the four countries in 1990 and 2019 were compared. R4.3.0 was used to construct an autoregressive moving average mixed model to predict the attributable disease burden in each country over the next decade. Results Compared with 1990, in 2019, the standardized incidence rate, standardized prevalence rate, standardized mortality rate, and standardized DALYs rate in China and the other two countries, except the United States, showed an increase. People aged 10 to 49 years old were a key group for disease burden, and the main risk factors for disease burden varied among different countries and age groups. The autoregressive moving average mixed model predicted that the main risk factor for Russia in the next decade would be injecting drugs, while unsafe sexual behavior would occur in the other three countries. Conclusion There are differences in disease burden and risk factors among different genders and age groups globally and in the four different SDI countries. Therefore, differences should be fully considered to determine the focus of HIV/AIDS prevention and control and rationally allocate health resources.

Objective To observe the effect of oxycodone hydrochloride combined with parecoxib sodium preemptive analgesia on postoperative pain in patients undergoing gynecologic laparoscopic surgery.Methods The clinical data of patients who underwent gynecological laparoscopic surgery at the General Hospital of Huainan Oriental Hospital Group from July 2021 to February 2023 were retrospectively analyzed and the patients were divided into a control group(parecoxib sodium)and a combined group(oxycodone hydrochloride combined with parecoxib sodium)according to the different preemptive analgesic regimens.The observational indexes of this study included opioid consumption within 24 h postoperatively,visual analog scale(VAS)scores at 0,2,6,12 and 24 h postoperatively,the number of effective presses of the patient controlled analgesiac(PCA),the time of the first press of the PCA,the number of remedial analgesia,the satisfaction of analgesia,and the occurrence of postoperative adverse reactions.Results A total of 80 patients were included in the study,with 39 in the control group and 41 in the combined group.The time of the first press of the analgesic pump was significantly longer in the combined group than in the control group(P＜0.05),while the number of effective presses and sufentanil consumption were significantly lower in the combined group than in the control group(P＜0.05).The difference in the number of remedial analgesia between the two groups was not statistically significant(P＞0.05).The VAS scores at 0 h,2 h and 6 h postoperatively in the combined group were significantly lower than those in the control group(P＜0.05),and the differences between the VAS scores at 12 h and 24 h postoperatively were not statistically significant(P＞0.05).The analgesic satisfaction score of patients in the combined group was significantly higher than that of the control group(P＜0.05),and the difference in the incidence of adverse reactions was not statistically significant(P＞0.05).Conclusion The preemptive analgesia regimen of oxycodone hydrochloride combined with parecoxib sodium significantly reduced the consumption of opioid drugs in patients after gynecological laparoscopic surgery,alleviated postoperative pain,and improved patient satisfaction.

Myeloid neoplasms (MNs) belong to a group of hematological malignancies characterized by the abnormal biological functions of hematopoietic stem progenitor cells. The abnormal immune and hematopoietic microenvironment of patients with MN interact with malignant clonal hematopoietic stem cells, promoting the occurrence and development of their diseases. MN large granular lymphocyte proliferation (MN-LGLP) is a special and rare clinical phenomenon in this type of disease. Currently, research on this disease in domestic and international cohorts is limited. This study analyzes the clinical and laboratory characteristics of this type of patient and explores the impact of LGLP on the clinical characteristics and survival of patients with MN. Patients with MN-LGLP are prone to neutropenia and splenomegaly. The presence of LGLP is not a risk factor affecting the survival of patients with MN-LGLP. STAG, ASXL1, and TET2 are the most common accompanying gene mutations in MN-LGLP, and patients with MN-LGLP and STAG2 mutations have poor prognoses.
