Objective:
To explore incidence trend of hepatitis C in Chifeng City, Inner Mongolia Autonomous Region from 2008 to 2022, so as to provide the basis for formulating prevention and control measures for hepatitis C.
Methods:
Data of reported hepatitis C cases in Chifeng City from 2008 to 2022 was collected through the Infectious Disease Information Reporting Management System. Trends in incidence of hepatitis C were analyzed using annual percent change (APC) and average annual percent change (AAPC). Impact of age, period and birth cohort on the risk of developing hepatitis C were analyzed by an age-period-cohort model.
Results:
The annual average reported incidence rate of hepatitis C in Chifeng City was 59.13/105 from 2008 to 2022. The incidence showed an upward trend from 2008 to 2018 (APC=9.405%, P<0.05) and a downward trend from 2018 to 2022 (APC=-17.475%, P<0.05), but the overall trend was not statistically significant (AAPC=0.937%, P>0.05). The age-period-cohort model analysis showed that the incidence risks of hepatitis C in the residents aged 0 to 4 years and 45 to 84 years were higher than those in the residents aged 40 to 44 years (the control group). The incidence risk of hepatitis C increased with age from 40 to 79 years. Compared with 2008-2012, the incidence risk of hepatitis C showed an increasing trend followed by a decline in 2008-2022. The incidence risk was higher in 2013-2017 and lower in 2018-2022 than in 2008-2012. The incidence risk of hepatitis C showed an increasing trend followed by a decreasing trend by using the birth cohort from 1968 to 1972 as the control. The birth cohort from 1953 to 1977 had a higher incidence risk of hepatitis C than other birth cohorts.
Conclusions
The overall incidence of hepatitis C in Chifeng City from 2008 to 2022 appeared a tendency towards a decline, and the incidence risk increased with age. Screening and health education for the elderly and high-risk birth cohorts should be strengthened.

Objective:To systematically retrieve, analyze and evaluate risk prediction models of postoperative urinary retention, so as to provide a basis for the application and optimization of the model.Methods:The research on the risk prediction model of postoperative urinary retention was electronically retrieved in PubMed, Web of Science, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure, WanFang Data, VIP, China Biology Medicine disc and other databases. The language of the literature was Chinese or English. The search period was from database establishment to February 20, 2023. Two researchers independently conducted literature screening and data extraction, and independently evaluated the bias risk and applicability of the included literature using the Prediction Model Risk of Bias Assessment Tool.Results:A total of 10 articles were included, including 17 risk prediction models for postoperative urinary retention. The areas under the receiver operating characteristic curve of 17 models were 0.700 to 0.920. The five most common predictors included in the model were age, gender, postoperative analgesia, diabetes, and operation time. The applicability of the model was good among the 10 studies, but there was some bias, mainly due to insufficient sample size, neglect of missing data and processing methods, overfitting issues, conversion of continuous variables into binary variables, and use of single factor screening for predictive factors.Conclusions:The risk prediction model of postoperative urinary retention has good prediction performance, but there is a certain risk of bias. The clinical value of the model needs further verification. External validation and continuous optimization are required for existing prediction models. Prospective research should also be carried out to develop a universal prediction model with good prediction performance, so as to provide an accurate and practical tool for clinical evaluation of postoperative urinary retention.

Objective:To evaluate the efficacy and safety of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of pseudomyxoma peritonei (PMP).Methods:In this descriptive case series study, we retrospective analyzed the records of PMP patients treated with CRS and HIPEC between January 2013 and June 2023 at Affiliated Cancer Hospital and Institute of Guangzhou Medical University. The inclusion criteria were as follows: (1) Aged 18 to 75 years and nonpregnant women. (2) Histologically confirmed diagnosis of pseudomyxoma peritonei. (3) Karnofsky Performance Scale (KPS)>70. (4) The functions of major organs such as the heart, liver, lungs, and kidneys can tolerate major surgery for long periods of time. (5) No evidence of extra-abdominal metastasis. Patients with extensive intra-abdominal adhesions or severe infectious diseases were excluded. The main outcomes were overall survival (OS) and postoperative major complications. The postoperative major complications were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 5.0). We used the peritoneal cancer index (PCI) score to quantitatively assess the peritoneal metastases and the completeness of cytoreduction (CCR) score at the end of surgery (CCR-0 and CCR-1 considered to be complete CRS).Results:A total of the 186 PMP patients with a median age of 56 (interquartile range extremes (IQRE), 48-64) years were included, 65 (34.9%) males and 121 (65.1%) females. The median peritoneal cancer index (PCI) score was 28 (20-34). Appendiceal origin accounted for 91.4%. Histological types were low grade in 99 patients (53.2%), high grade in 57 patients (30.6%), and 55 patients (29.6%) received complete cytoreduction (CCR-0/1). The median operative duration was 300 (211-430) minutes for all patients. Treatment-related 30-day mortality was 2.7%; 90-day mortality 4.3%; reoperation 1.6%; and severe morbidity 43.0%. Within the entire series, anemia(27.4%), electrolyte disturbance(11.6%), and hypoalbuminemia(7.5%) were the most frequent major complications (grade 3-4). The incidences of gastrointestinal anastomotic leakage, abdominal bleeding, and abdominal infection were 2.2%, 2.2%, and 4.3%, respectively. After a median follow-up of 38.1 (95%CI:31.2-45.1) months, the 5-year OS was 50.3% (95%CI: 40.7%-59.9%) with a median survival time of 66.1 (95%CI: 43.1-89.1) months. The survival analysis showed that patients with pathological low grade, low PCI, and low CCR score had better survival with statistically significant differences (all P<0.05). Further stratified into complete and incomplete CRS subgroups, the 5-year OS of the CCR-0 and CCR-1 subgroups was 88.9% (95%CI: 68.3%-100.0%) and 77.6% (95%CI: 62.7%-92.5%), respectively; and 42.0% (95%CI: 29.5%-54.5%) in the CCR-2/3 subgroup. Conclusions:CRS and HIPEC may result in a long-term survival benefit for PMP patients with acceptable perioperative morbidity and mortality. This strategy, when complete CRS is possible, could significantly prolong survival for strictly selected patients at experienced centers.

ObjectiveTo study the effect of Bufei Tongbi decoction on pulmonary fibrosis in diabetic rats via the transforming growth factor-β1 (TGF-β1)/phosphorylated Smad family member 3 (p-Smad3) signaling pathway. MethodsStreptozotocin (60 mg·kg-1) and bleomycin (24.80 U·kg-1) were used to prepare the rat model of diabetes with pulmonary fibrosis by intratracheal injection. Sixty rats were randomly assigned into blank, model, low-, medium-, and high-dose (3.98, 7.95, and 15.90 g·kg-1, respectively) Bufei Tongbi decoction, and pirfenidone (0.36 mg·kg-1) groups (n=10). The successfully modeled rats in each group were administrated with corresponding agents once per day for four consecutive weeks. After drug administration, fasting blood glucose and lung function indicators were measured. Chemical immunoassay was employed to determine the serum levels of hydroxyproline (Hyp), hyaluronic acid (HA), and laminin (LN). The lung index was determined by the wet and dry methods. The pathological changes in the lung tissue were observed by hematoxylin-eosin (HE) staining, and the degree of fibrosis was detected by Masson staining. The mRNA and protein levels of TGF-β1, p-Smad3, Smad3, α-smooth muscle actin (α-SMA), collagen type Ⅰ alpha 1 (Col1A1), and fibronectin were determined by PCR and Western blotting, respectively. ResultsCompared with the blank group, the model group showed alveolar septa thickening, obvious thickening of the basement membrane of pulmonary blood vessels, severe destruction of the alveolar structure, structural disarrangement of the lung parenchyma, and an increase in the proportion of inflammatory cell infiltration in the lung tissue, together with a large amount of blue collagen deposition and a large amount of collagen fibroplasia in the bronchial wall, vessel wall, interstitium, and alveolar wall, which indicated severe fibrosis. Bufei Tongbi decoction groups and the pirfenidone group showed lower fasting blood glucose level (P<0.05) and higher forced vital capacity (FVC), cytoplasmic dynein (Cydn), FEV0.3/FEV ratio, and lung index (P<0.05) than the model group. Moreover, these groups demonstrated alleviated lung fibrosis, elevated Hyp, HA, and LN levels, down-regulated mRNA levels of α-SMA, Col1A1, and fibronectin, and down-regulated protein levels of TGF-β1, Smad3, p-Smad3, α-SMA, Col1A1, and fibronectin (P<0.05). ConclusionBufei Tongbi decoction can inhibit pulmonary fibrosis in diabetic rats by inhibiting the TGF-β1/p-Smad3 signaling pathway.

Atherosclerosis (AS) is a chronic inflammatory pathological process in which lipid and/or fibrous substances are deposited in the intima of arteries, and it is one of the pathological bases of many cardiovascular and cerebrovascular diseases. Endoplasmic reticulum stress (ERS) is a protective mechanism of cell adaptation. Moderate ERS can reduce abnormal protein aggregation and increase the degradation of misfolded proteins to repair and stabilize the internal environment, while excessive ERS can cause unfolded protein reaction, activate inflammation, oxidative stress, apoptosis, autophagy, and other downstream pathways, and lead to cell damage, or even apoptosis. A large number of studies have shown that ERS mediates a variety of pathological processes related to AS, affects endothelial cells, smooth muscle cells, macrophages, endothelial progenitor cells, and other cell components closely related to its occurrence and development, influences the progress of AS by regulating cell function, and promotes the formation of AS plaque, the transformation of stable plaque to unstable plaque, and the rupture of unstable plaque. Regulation of ERS may be a key target for the prevention and treatment of AS, and it is a research hotspot at present. Traditional Chinese medicine (TCM) believes that the origin of AS is the imbalance of Yin and Yang, the disharmony of Zangfu organs, and the abnormal operation of Qi, blood, and body fluid, which leads to the accumulation of phlegm, blood stasis, and other pathological products in the pulse channels, making the blood flow blocked or misfunction and causing the disease, which belongs to the syndrome of deficiency in origin and excess in superficiality. As the pathogenesis of AS is complex, and the symptoms are diverse, TCM has significant advantages in treating AS because of its multiple targets, multiple pathways, stable efficacy, strong individualization, and high safety. This paper systematically elaborated on the role of ERS in the occurrence and development of AS and summarized the mechanism research on the regulation and control of ERS by Chinese herbal monomer, Chinese herbal extract, Chinese herbal compound, and proprietary medicine, so as to provide a theoretical basis for clinical research and drug development in the prevention and treatment of AS.

The basic pathological change of diabetic macroangiopathy is atherosclerosis (AS), which is mainly associated with vascular endothelial cells (VECs) injury, oxidative stress, glucose and lipid metabolism disorders, hemorheological abnormalities, and endoplasmic reticulum stress. The injury and dysfunction of VECs are the initiating factors of diabetic macroangiopathy. Autophagy is a subcellular self-protection mechanism that regulates basic intracellular metabolism through lysosome-mediated degradation of proteins and damaged organelles to maintain homeostasis. Insufficient autophagy of VECs leads to enhanced inflammation, apoptosis, and oxidative stress of VECs, which promotes AS. According to the theory of traditional Chinese medicine (TCM), diabetic macroangiopathy corresponds to the syndrome of internal deficiency and pathogen invasion, with Qi deficiency and stagnation as the key pathogenesis. Qi deficiency is the root cause, and Qi stagnation is the manifestation. The disease occurs with the initial cause of nutrient-defense disharmony and instability of vessels, the main cause of the deficiency of kidney Qi and the lack of source for generation and transformation, the internal cause of Qi and blood loss in the viscera and the stagnation of Qi, blood, and fluid, and the superficial cause of the stagnation of pathological products and the damage of vessels. Autophagy is a microscopic manifestation of Qi, which has the function of dispelling pathogens and maintaining homeostasis. Insufficient autophagy of VECs leads to Qi deficiency and stagnation, and the gradual deficiency and heavy stagnation of Qi lead to insufficient autophagy, which form a vicious cycle. Modern research has demonstrated that regulating the autophagy of VECs is the main way to prevent and treat AS, and TCM can exert the therapeutic effect in a multi-target and multi-pathway manner. Therefore, based on the theory of Qi deficiency and stagnation, the method of tonifying deficiency of and removing stagnation can be adopted to select prescriptions for regulating the autophagy of VECs and treating AS, which can slow down the procession of diabetic macroangiopathy.

Currently, in precision cardiac surgery, there are still some pressing issues that need to be addressed. For example, cardiopulmonary bypass remains a critical factor in precise surgical treatment, and many core aspects still rely on the experience and subjective judgment of cardiopulmonary bypass specialists and surgeons, lacking precise data feedback. With the increasing elderly population and rising surgical complexity, precise feedback during cardiopulmonary bypass becomes crucial for improving surgical success rates and facilitating high-complexity procedures. Overcoming these key challenges requires not only a solid medical background but also close collaboration among multiple interdisciplinary fields. Establishing a multidisciplinary team encompassing professionals from the medical, information, software, and related industries can provide high-quality solutions to these challenges. This article shows several patents from a collaborative medical and electronic information team, illustrating how to identify unresolved technical issues and find corresponding solutions in the field of precision cardiac surgery while sharing experiences in applying for invention patents.
