This article systematically analyzes the historical evolution of the name, medicinal parts, origin, harvesting, processing and other aspects of Houttuyniae Herba(HH) by referring to the medical books, prescription books and other documents of the past dynasties, combined with the research materials related to modern and contemporary times, in order to provide a basis for the development of famous classical formulas containing this herb. In ancient literature, HH was often referred to as "Ji" and "Jicai", the name of "Ji" was first recorded in Mingyi Bielu during the Han and Wei dynasties, and the name of Yuxingcao was first seen in Lyuchanyan Bencao during the southern Song dynasty and has continued to this day. The origin of HH used throughout history is consistent, all of which are the whole herb or aboveground parts of Houttuynia cordata in Saururaceae family. HH recorded throughout history has a wide range of production areas, mostly self-produced self-marketing. In ancient times, fresh HH was often used as medicine by pounding its juice without involving any processing steps. Both fresh and dried products can be used as medicine, the fresh products uses the whole plant, while the dried products uses the aboveground parts, which are cleaned, selected and processed before use. Fresh products are harvested regardless of season, while dried products are harvested in both summer and autumn, with summer as the best. In ancient times, there were no specific requirements for the quality of HH, while in modern times, "intact stems and leaves with a strong fishy smell" are preferred. In addition, the medicinal properties of HH have undergone significant changes from ancient to modern times. In the early period, it was believed that its medicinal property was slightly warm, until the 1977 edition of Chinese Pharmacopoeia officially changed it to slightly cold. Both ancient and modern literature states that HH can be used for the treatment of carbuncle and malignant sores, Lyuchanyan Bencao for the first time introduced HH fresh juice can relieve summer heat, since Diannan Bencao recorded that it can be used for lung carbuncle, and gradually developed into the first choice for the treatment of lung carbuncle. Based on the research results, it is suggested that fresh herb or dried aboveground parts of H. cordata are used as medicine when developing famous classical formulas.

Objective To explore the mechanism by which zinc-regulated transporters, iron-regulated transporter-likeprotein 4 (ZIP4) regulates glycolysis and its impact on tumor progression in cholangiocarcinoma (CCA), providing a theoretical basis for targeted therapy of CCA. Methods ZIP4 expression in CCA was analyzed using the GEPIA database. Immuno-histochemistry (IHC) was used to detect ZIP4 expression in 20 paired CCA and adjacent non-tumor tissues. Stable ZIP4-overexpressing CCA cell lines (ZIP4-OE) were established. Gene set enrichment analysis was used to screen differentially expressed genes and pathways in ZIP-OE CCA cells. ZIP4, N-myc proto-oncogene protein (MYCN), and histone-lysine N-methyltransferase 2E (KMT2E) were knocked down using small interfering RNAs (siRNAs). The expression of glycolysis-related gene (glucose transporter 1 [Glut1], hexokinase 2 [HK2], and lactate dehydrogenase A [LDHA]) was measured by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). Glycolytic activity was assessed by measuring the extracellular acidification rate (ECAR). Cell proliferation was evaluated using colony formation assays, and cell migration was assessed using Transwell assays. A xenograft mouse model was constructed to examine CCA tumor growth. Protein levels of ZIP4, KMT2E, H3K4me3 (tri-methylation of lysine 4 on histone H3), and MYCN were detected by Western blotting. Results GEPIA database analysis and IHC results confirmed significantly higher ZIP4 expression levels in CCA tissues compared to adjacent non-tumor tissues (P<0.05). Compared to the control group, the ZIP4-OE group exhibited a significantly increased ECAR, along with significantly enhanced proliferation and migration abilities (P<0.01). Conversely, knockdown of ZIP4 suppressed CCA cells proliferation and migration. GEPIA analysis indicated that ZIP4 upregulates the transcription of oncogene MYCN, as well as glycolysis-related genes. Knockdown of MYCN abolished the ZIP4 overexpression-induced upregulation of Glut1, HK2, and LDHA gene transcription, reduced glycolysis, and significantly inhibited CCA cell proliferation and migration (P<0.05). Mechanistic studies demonstrated that ZIP4 increases H3K4me3 level via KMT2E, leading to MYCN transcription. Knockdown of KMT2E in CCA cells suppressed the ZIP4 overexpression-induced enhancement in H3K4me3 modification, resulting in MYCN downregulation and significantly reduced CCA cells proliferation and migration (P<0.05). Conclusions ZIP4 upregulates H3K4me3 modification through KMT2E, which recruits transcription factors to activate the transcription of MYCN. This subsequently enhances cellular glycolysis and promotes the proliferation and migration of CCA cells.

Objective:
To evaluate the effectiveness for the construction of the "mosquito-free village" in Jinzishan Village, Fuling District, Chongqing Municipality, so as to provide references for improving mosquito control practices in hilly and mountainous rural areas.
Methods:
The "mosquito-free village" initiative in Fuling District was launched in April 2023. Mosquito density monitoring was conducted annually from April to October. Larval mosquito density was monitored using the path method and scoop-catch method, and adult mosquito density was monitored using human-baited landing catch. One hundred and fifty-two villagers were randomly conducted before the "mosquito-free village" construction (April 2023) and one hundred and sixty-seven villagers were randomly conducted after the construction (November 2024). Knowledge awareness rate and correct behavioral practices regarding mosquito control among villagers were assessed. The satisfaction among villagers were evaluated in November 2024. The effectiveness of the initiative was evaluated based on mosquito density data, health education outcomes from 2023 to 2024, and satisfaction.
Results:
The average larval mosquitoes path index in Jinshanzi Village decreased from 1.50 spots/km in 2023 to 0.07 spots/km in 2024 (P<0.05). The average sampling spoon index of larval mosquitoes decreased from 3.43% in 2023 to 0 in 2024. The average landing rate index of adult mosquitoes decreased from 3.90 mosquitoes/(person·time) in 2023 to 0.38 mosquitoes/(person·time) in 2024 (P<0.05). The awareness rate of mosquito control knowledge and the formation rate of correct behaviors among villagers increased from 59.87% and 57.24% in 2023 to 92.22% and 90.42% in 2024, respectively (both P<0.05). In 2024, the satisfaction of villagers was 92.81%.
Conclusion
The mosquito density, health education effectiveness, and satisfaction of villagers in Jinzishan Village have all met the evaluation criteria for a "mosquito-free village", providing a replicable model for promotion in hilly and mountainous rural areas.

OBJECTIVES:
To study the molecular mechanisms of LDH-loaded si-NEAT1 for regulating paclitaxel resistance and tumor-associated macrophage (TAM) polarization in breast cancer.
METHODS:
qRT-PCR and Western blotting were used to detect the expression of lncRNA NEAT1, miR-133b, and PD-L1 in breast cancer SKBR3 cells and paclitaxel-resistant SKBR3 cells (SKBR3-PR). The effects of transfection with si-NEAT1 and miR-133b mimics on MRP, MCRP and PD-L1 expressions and cell proliferation, migration and apoptosis were investigated using qRT-PCR, Western blotting, scratch and Transwell assays, and flow cytometry. Rescue experiments were conducted using si-NEAT1 and miR-133b inhibitor. Human THP-1 macrophages were cultured in the presence of conditioned media (CM) derived from SKBR3 and SKBR3-PR cells with or with si-NEAT1 transfection for comparison of IL-4-induced macrophage polarization by detecting the surface markers. LDH@si-NEAT1 nanocarriers were constructed, and their effects on MRP, MCRP and PD-L1 expressions and cell behaviors of the tumor cells were examined. THP-1 cells were treated with the CM from LDH@si-NEAT1-treated tumor cells, and the changes in their polarization were assessed.
RESULTS:
SKBR3-PR cells showered significantly upregulated NEAT1 and PD-L1 expressions and lowered miR-133b expression as compared with their parental cells. Transfection with si-NEAT1 and miR-133b mimics inhibited viability, promoted apoptosis and enhanced MRP and BCRP expressions in SKBR3-PR cells. NEAT1 knockdown obvious upregulated miR-133b and downregulated PD-L1, MRP and BCRP expressions. The CM from SKBR3-PR cells obviously promoted M2 polarization of THP-1 macrophages, which was significantly inhibited by CM from si-NEAT1-transfected cells. Treatment with LDH@si-NEAT1 effectively inhibited migration and invasion, promoted apoptosis, and reduced MRP, BCRP and PD-L1 expressions in the tumor cells. The CM from LDH@si-NEAT1-treated SKBR3-PR cells significantly downregulated Arg-1, CD163, IL-10, and PD-L1 and upregulated miR-133b expression in THP-1 macrophages.
CONCLUSIONS
LDH@si-NEAT1 reduces paclitaxel resistance of breast cancer cells and inhibits TAM polarization by targeting the miR-133b/PD-L1 axis.

Objective:To evaluate the effect of lung recruitment maneuvers combined with individualized positive end-expiratory pressure(PEEP) on the degree of postoperative atelectasis in elderly patients undergoing laparoscopic surgery.Methods:One hundred and forty-three elderly patients, aged ≥65 yr, with body mass index of 18.5-30.0 kg/m 2, scheduled for elective laparoscopic surgery, were assigned to either individualized PEEP combined with recruitment maneuvers (group Ⅱ) or fixed PEEP (group Ⅰ) using a random number table method. PEEP was maintained at 6 cmH 2O starting from the beginning of procedure until the end of the procedure in group I. Individualized PEEP titration was performed after induction of anesthesia in group Ⅱ. The primary outcome measure was the 12-zone lung ultrasound score at 15 min after tracheal extubation. Other outcome measures were the occurrence of postoperative pulmonary complications within 7 days after surgery, Quality of Recovery-15 scale score on 3rd day after surgery, rate of unplanned admission to intensive care units, length of hospital stay, incidence of intraoperative hypoxemia, usage rate of intraoperative vasoactive drugs, and incidence of postoperative hypotension. Results:Compared with group Ⅰ, the lung ultrasound score, driving pressure and postoperative pulmonary complications were significantly decreased, the dynamic lung compliance was increased ( P<0.05 or 0.01), and no significant changes were found in the other parameters in group Ⅱ ( P>0.05). Conclusions:Individualized PEEP combined with recruitment maneuvers can reduce the degree of postoperative atelectasis in elderly patients undergoing laparoscopic surgery.

Nasal drug delivery efficiency is highly dependent on the position in which the drug is deposited in the nasal cavity. However, no reliable method is currently available to assess its impact on delivery performance. In this study, a biomimetic nasal model based on three-dimensional (3D) reconstruction and three-dimensional printing (3DP) technology was developed for visualizing the deposition of drug powders in the nasal cavity. The results showed significant differences in cavity area and volume and powder distribution in the anterior part of the biomimetic nasal model of Chinese males and females. The nasal cavity model was modified with dimethicone and validated to be suitable for the deposition test. The experimental device produced the most satisfactory results with five spray times. Furthermore, particle sizes and spray angles were found to significantly affect the experimental device's performance and alter drug distribution, respectively. Additionally, mometasone furoate (MF) nasal spray (NS) distribution patterns were investigated in a goat nasal cavity model and three male goat noses, confirming the in vitro and in vivo correlation. In conclusion, the developed human nasal structure biomimetic device has the potential to be a valuable tool for assessing nasal drug delivery system deposition and distribution.

Objective:To explore the safety and feasibility of adrenal tumor resection under day surgery mode for the treatment of unilateral primary aldosteronism (UPA).Methods:The clinical data of 83 patients who underwent adrenalectomy for the treatment of UPA from January 2020 to January 2023 were retrospectively analyzed. There were 42 males (50.6%)and 41 females (49.4%), age (49.0±12.3)years old. Body mass index (25.4±3.6)kg/m 2. There were 17 patients with diabetes, 58 patients with preoperative hypertension, and the duration of hypertension was 8.2(1, 15)years. Systolic blood pressure was 151.8(137.0, 160.0)mmHg (1 mmHg=0.133 kPa), and diastolic blood pressure was 97.4(87.0, 107.0)mmHg. 20 cases had severe preoperative hypokalemia, with preoperative blood potassium levels of (2.9±0.6)mmol/L. The ratio of preoperative plasma aldosterone to renin activity was 54.1(13.0, 77.2). Tumors were located on the left side in 47 cases (56.6%)and on the right side in 36 cases (43.4%). The maximum diameter of the tumor is 1.5(1.0, 1.7)cm. Patients diagnosed with unilateral primary aldosteronism were included, and patients diagnosed with adrenal pheochromocytoma, adrenal malignancy, or severe cardiovascular disease that cannot tolerate surgery were excluded. The patient was admitted to the hospital on the same day, underwent surgery on the same day, and was evaluated after extubation within one day after surgery. The patient had no fever or lower back pain after surgery, was able to freely get out of bed, and had no obvious abnormalities in blood routine, electrolyte and other test indicators. The patient was discharged from the hospital and received continuous care outside the hospital. The patient was guided to undergo regular outpatient follow-up. Evaluate the efficacy using the Primary Aldosterone Hyperaldosteronism Surgical Outcome (PASO)criteria. Results:The patients had a mean length of hospital stay of 43.0(40.3, 44.6)hours, an operation time of 89.6(70.0, 103.0)minutes, and an operation cost of 23 820.2 (21 150.8, 24 948. 3)yuan. The postoperative free position time was 29.5(20.8, 39.7)hours, the postoperative time for fluid placement of the diet was 25.2(20.1, 27.8) hours, and 42.2(37.9, 41.9)hours of postoperative drain removal. The overall postoperative clinical remission rate was 85.5%. There were four postoperative complications, accounting for 4.8% of cases. These included two cases of interosseous vein thrombosis, one case of delayed healing, and one case of peritoneal rupture. No case of readmission was reported within 30 days.Conclusions:UPA adrenal tumour resection in ambulatory mode is safe and effective when strict inclusion and exclusion criteria are followed, adequate preoperative preparation is carried out, and expert physician assessment is provided.
