[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

OBJECTIVE To establish a method for simultaneous determination of 7 anti-tumor drugs (irinotecan, capecitabine, paclitaxel, docetaxel, tamoxifen, letrozole and methotrexate) in human plasma and apply it to the clinic. METHODS After precipitating with a methanol-acetonitrile mixture (1∶ 1, V/V) containing 0.1% formic acid, liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to determine the plasma concentration, using deuterium isotopes of each analyte as internal standards. The chromatography was performed on the Agilent Eclipse Plus C18 column with a gradient elution of water (containing 0.1% formic acid+0.04% 5 mmol/L ammonium formate) as mobile phase A and acetonitrile (containing 0.1% formic acid) as mobile phase B. The flow rate was 0.6 mL/min, and the column temperature was set at 40 ℃ . The sample size was 10 μL, and the analysis lasted for 5.5 min. Electrospray ionization was used in positive and negative ion mode, and multiple reaction monitoring mode was used. The ion pairs used for quantitative analysis were m/z 587.1→167.1 (irinotecan), m/z 360.1→244.1 (capecitabine), m/z 876.4→308.0 (paclitaxel), m/z 830.3→304.2 (docetaxel), m/z 372.1→129.1 (tamoxifen), m/z 284.1→242.1 (letrozole), and m/z 455.0→ 308.0 (methotrexate). A total of 97 patients with malignant tumors in our hospital were selected to measure the plasma concentrations of 7 anti-tumor drugs using the above method. RESULTS The linear ranges of irinotecan, capecitabine, paclitaxel, docetaxel, tamoxifen, letrozole and methotrexate were 2-1 000 ng/mL (r=0.994 3), 20-10 000 ng/mL (r=0.997 5), 2-1 000 ng/mL (r=0.997 9), 1-500 ng/mL (r=0.995 8), 1-500 ng/mL (r=0.995 2), 1-500 ng/mL (r=0.996 4), 10-5 000 (r=0.997 7), respectively. The quantitative lower limits were 2, 20, 2, 1, 1, 1 and 10 ng/mL; RSDs of intra-assay precision were 0.08%-14.86% (n=6). RSDs of inter-batch precision were 1.51%-11.55% (n=3), and the accuracies were 89.17%-114.93% (n=6). The matrix effects ranged from 89.89%-119.74% (n=6). RSDs of the stability tests were 1.98%-14.88% (n=6). The results of E-mail:hangpengzhou@163.com clinical application showed, the average plasma concentrations of irinotecan, capecitabine, paclitaxel and docetaxel were 704.09, 909.40, 36.45, 150.43 ng/mL, respectively. The values of the coefficient of variation were 25.24%, 62.65%, 122.69%, and 92.27%. CONCLUSIONS The established LC-MS/MS method is simple and rapid, and can be used for the simultaneous determination of 7 commonly used anti-tumor drugs in the plasma of patients with malignancy.

ObjectiveTo investigate the analgesic effect of Tuina at the "Weizhong (BL 40)" on neuropathic pain in a rat model of chronic constriction injury (CCI) of the sciatic nerve and its potential central spinal mechanisms. MethodsThirty-two Sprague-Dawley rats were randomly divided into four groups (8 rats in each group), sham-operated group, model group, Tuina group, and blockade group. The CCI model was established in the model group, Tuina group, and the blockade group by ligating the sciatic nerve with catgut, while the sham-operated group underwent only sciatic nerve exposure without ligation. From postoperative day 4 to day 14, rats in the Tuina group and the blockade group received Tuina manipulation at the "Weizhong (BL 40)" using a dynamic pressure distribution measurement system (5 N pressure, 2 Hz frequency, 10 min per session, once daily). The blockade group also received intraperitoneal injections of the microglial inhibitor minocycline (10 mg/kg) once daily. The sham-operated and the model group underwent the same handling and fixation as the Tuina group without actual Tuina. Mechanical withdrawal threshold (MWT) and paw withdrawal latency (PWL) were measured before surgery and on day 3, 7, 10, and 14 post-surgery. Transmission electron microscopy was used to evaluate sciatic nerve injury and repair, measuring axon diameter and total myelinated fiber diameter to calculate the g-ratio. Western Blotting was performed to detect the protein levels of ionized calcium-binding adapter molecule 1 (Iba-1), CD206, CD68, interleukin-10 (IL-10), and β-endorphin (β-EP) precursor pro-opiomelanocortin (POMC) in the ipsilateral spinal dorsal horn. ResultsCompared with the sham-operated group, the model group showed significantly reduced MWT and PWL on day 3, 7, 10, and 14 (P<0.01). Compared with the model group, the Tuina group and the blockade group showed increased MWT and PWL on day 10 and 14 (P<0.05). Compared with the Tuina group, the blockade group exhibited higher MWT on day 7, 10, and 14, and higher PWL on day 10 (P<0.05). Sciatic nerve pathological morphology revealed intact and well-structured myelin in the sham-operated group, while the model group exhibited myelin collapse, distortion, and myelin ovoid formation. The Tuina group displayed partially irregular myelin with occasional myelin collapse, whereas the blockade group exhibited partial myelin irregularities and phospholipid shedding. Compared with the sham-operated group, the model group showed a decreased g-ratio and increased levels of Iba-1 and CD68 in the spinal dorsal horn (P<0.05 or P<0.01). Compared with the model group, the Tuina group and the blockade group exhibited an increased g-ratio and reduced Iba-1 and CD68 levels. Additionally, the Tuina group showed elevated levels of CD206, IL-10, and POMC, whereas the blockade group had decreased CD206 levels (P<0.05). ConclusionTuina at "Weizhong (BL 40)" alleviates neuropathic pain in CCI rats, potentially by regulating microglial activation in the spinal cord, inhibiting M1 polarization while promoting M2 polarization, and activating the IL-10/β-EP pathway to exert analgesic effects.

With the rapid advancement of refractive surgery, small incision lenticule extraction(SMILE)has become a mainstream procedure due to its biomechanical advantage in preserving the integrity of the anterior elastic layer and epithelium. However,postoperative stromal tissue removal and stress redistribution may still compromise corneal biomechanical stability, potentially affecting long-term corneal stability and visual quality. This review focuses on the mechanisms underlying biomechanical changes after SMILE, summarizing recent findings on corneal thinning, reduced mechanical strength, and stress remodeling, and their impact on corneal morphology and visual quality. It further explores potential contributors to postoperative ectasia, increased higher-order aberrations(HOAs), and visual fluctuations, highlighting individual variability and current controversies in the literature. Moreover, current evidence on adjunctive strategies such as corneal cross-linking(CXL)in enhancing biomechanical strength, reducing complications, and improving optical quality was analyzed. Finally, optimal timing for CXL, threshold values of biomechanical metrics, and the role of individualized preoperative assessment and postoperative management was discussed, aiming to provide a theoretical and clinical basis for improving safety and visual outcomes following SMILE.

Guided by the theories of yin-yang and collateral disease, this paper identifies the dysregulation of yang qi ascent and descent as the core pathomechanism of hypertension. Based on clinical experience, a treatment approach centered on the method of raising yang and promoting descent was proposed. Clinically, three major syndrome types were identified. Firstly, deficiency of zong qi (ancestral qi) with blood stasis, obstruction of phlegm-turbidity and blood stasis, and hyperactivity of liver yang. Corresponding empirical formulation, Yizong Huoxue Decoction (益宗活血汤) was applied to tonify zong qi, invigorate blood, and raise yang. Secondly, Lizong Huoxue Decoction (理宗活血汤) was used to resolve phlegm, promote yang qi circulation, and regulate qi and blood. Thirdly, Qinggan Tongluo Decoction (清肝通络饮) was used to clear the liver, dredge collaterals, and subdue hyperactive yang. For special types such as non-dipper hypertension, time-specific syndrome differentiation and treatment can be applied based on a thorough understanding of the underlying pathomechanism, aiming to provide new insights into clinical diagnosis and treatment of hypertension.

Through data collection and collation combined with bibliometrics, this study conducted a series of textual research on Yanghetang, such as the name and origin, the evolution of prescription composition and modern clinical application. Yanghetang was first recorded in Bencao Yidu of WANG Ang in the Qing dynasty. In addition to Yanghetang, there were 3 bynames of Jiawei Yanghetang, Quanshengji Yanghetang and Zhenjun Yanghetang. Regarding the composition of the formula, a total of 4 versions of Yanghetang were collected. The first version is the 5 medicines version of Cervi Cornus Colla, Rehmanniae Radix Praeparata, Cinnamomi Cortex, Zingiberis Rhizoma and Ephedrae Herba in Bencao Yidu. The second version is the 7 medicines version of Waike Zhengzhi Quanshengji, changing Zingiberis Rhizoma to Zingiberis Rhizoma Praeparatum Carbonisata(ZRPC) and adding Sinapis Semen and Glycyrrhizae Radix et Rhizoma(GRR) on the basis of Bencao Yidu, and most of the Yanghetang is of this version. The third version is the 6 medicines version of Wushi Yifang Huibian, that is, on the basis of Bencao Yidu, Zingiberis Rhizoma is changed into ZRPC, and Sinapis Semen is added. The fourth version is the 6 medicines version in Yifang Jiedu, that is, on the basis of Bencao Yidu, Zingiberis Rhizoma is changed into Zingiberis Rhizoma Praeparatum, and GRR Praeparata cum Melle is added. Regarding the dose of Yanghetang, the doses of the medicines in Waike Zhengzhi Quanshengji was converted into the modern doses as follows:37.3 g of Rehmanniae Radix Praeparata, 1.87 g of Ephedrae Herba, 11.19 g of Cervi Cornus Colla, 7.46 g of Sinapis Semen, 3.73 g of Cinnamomi Cortex, 3.73 g of GRR, and 1.87 g of ZRPC. The origins of the above medicines are consistent with the 2020 edition of Chinese Pharmacopoeia. The processing specification of Rehmanniae Radix Praeparata is steaming method, ZRPC is ginger charcoal, Sinapis Semen is the fried products, and the rest of the medicines are raw products. The decoction method was verified by the decoction method in Chonglou Yuyao, which is similar in the time, and it is recommended that the above medicines should be added with 600 mL of water, decocted to 100 mL, and taken warmly 30 min after meal. For each dose, it is recommended to use 1-3 doses per day according to the doctor's advice in combination with clinical practice. The diseases involved in the ancient applications involved 42 diseases in 11 departments, including orthopedics, dermatology and gynecology, which were dominated by Yin-cold syndrome. However, the diseases involved in modern research also include 148 related diseases in 10 departments, such as orthopedics, obstetrics and gynecology, which is consistent with the ancient books. In recent years, the research hotspots of Yanghetang have focused on more than 10 fields, including osteoblasts, malignant tumors, wound healing, traditional Chinese medicine fumigation and so on, which are widely used. It is suitable for comprehensive research and development because of its rational formula composition, clear origin, processing and decoction method, and wide clinical application.

ObjectiveTo evaluate the pharmacological effect of Buzhong Yiqitang on brain development in offspring of rats with subclinical hypothyroidism (SCH) during pregnancy and explore its potential mechanism. MethodsForty-eight SPF female SD rats were divided into sham operation group (n=8) and model group (n=40). The rat model of subclinical hypothyroidism (SCH) was constructed by total thyroidectomy combined with postoperative subcutaneous injection of levothyroxine (L-T4). The modeled rats were randomly allocated into model, low-, medium-, and high-dose (5.58, 11.16, 22.32 g∙kg-1, respectively) Buzhong Yiqitang, and euthyrox (4.5×10-6 g∙kg-1) groups, with 8 rats in each group. These rats were co-housed with normal male rats for mating. Drug administration started 2 weeks before pregnancy and continued until delivery. Hematoxylin-eosin staining and Golgi-cox staining were used to observe pathological changes in the hippocampal tissue of offspring rats. Western blot was employed to detect the effects of Buzhong Yiqitang on the protein levels of cytochrome C oxidase subunitⅠ (COX)Ⅰ and COXⅣ in the hippocampal tissue of offspring rats. A colorimetric method was used to measure the mitochondrial adenosine triphosphate (ATP) content in the hippocampal tissue of offspring rats. For in vitro experiments, a hydrogen peroxide (H2O2)-induced oxidative damage model was established with rat pheochromocytoma cells (PC12). Interventions included the DNA methyltransferase inhibitor (SGI-1027), Buzhong Yiqitang-medicated serum, and euthyrox-medicated serum. The cell counting kit-8 (CCK-8) assay was used to examine the effect of Buzhong Yiqitang on cell proliferation. Immunofluorescence staining was performed to evaluate the effect on tubulin beta 3 class Ⅲ (TUBB3) in PC12 cells. Western blot was employed to assess the effects on the protein levels of DNA methyltransferases (TETs and DNMTs) in PC12 cells. The fluorescent probe 2′,7′-dichlorodihydrofluorescein diacetate (DCFH-DA), luciferase assay, and JC-1 staining were employed to assess the effects of Buzhong Yiqitang on the levels of reactive oxygen species (ROS) and ATP and the mitochondrial membrane potential in PC12 cells. ResultsCompared with the sham group, the model group showed a reduction in the number of hippocampal neurons, incomplete pyramidal cell bodies, loose arrangement, shortened average dendrite length, decreased dendritic complexity and dendritic spine density, and reduced expression levels of COXⅠ and COXⅣ and content of ATP in the brain tissue (P<0.05, P<0.01). Compared with the model group, after administration of Buzhong Yiqitang and euthyrox, hippocampal neurons exhibited regular arrangement, complete morphology, extended dendrite, increased dendritic complexity and dendritic spine density, and restored expression levels of COXⅠ and COXⅣ and content of ATP (P<0.05, P<0.01), with the medium-dose Buzhong Yiqitang group showing the best therapeutic effect. In the PC12 cell model of oxidative damage, Buzhong Yiqitang increased the cell viability (P<0.01), enhanced neuronal differentiation, down-regulated the expression levels of DNMTs (P<0.05), up-regulated the expression levels of TETs (P<0.05), decreased the ROS content (P<0.01), and restored the ATP content and mitochondrial membrane potential (P<0.01). ConclusionBuzhong Yiqitang protects brain development in offspring of pregnant rats with SCH. It mainly acts on the oxidative stress and mitochondrial dysfunction resulted from abnormal mtDNA methylation, with DNMTs and TETs as the key proteins for its effects.

Objective: To investigate the feasibility of magnetic anastomosis for uretero-ileal anastomosis using experimental rabbit models. Methods: Six experimental rabbits were used as the models.The lower part of the left ureter was cut with scissors,the daughter magnet (DM) was placed in the middle of the ureter,and the distal end of the ureter was ligated.After that,the ileum wall was opened,the parent magnet (PM) was inserted through it,the positions of the PM and DM were adjusted so that their ends were attracted to each other,and then ileum wall incision was sutured.The operation time,intraoperative blood loss,postoperative complications and magnet discharge time were recorded.Two weeks after operation,left ureterography was performed to obtain the specimens of the uretero-ileal anastomosis,and to observe the patency of the anastomosis.The formation of the anastomosis was observed with naked eyes and light microscope. Results: Uretero-ileal magnetic anastomosis was performed successfully in 6 experimental rabbits.The operation time was 28-39(32.50±3.94) min,and the intraoperative blood loss was less than 5 mL.The rabbits recovered well after operation,and no complications were observed.All animals survived to the end point of observation.The disconnection time of magnet after operation was 9-13(10.83±1.72) days.The gross specimen showed that the anastomosis was patent.The histological observation showed that the mucosa of the anastomosis was continuous and smooth,and the anastomosis was well formed. Conclusion: Magnetic anastomosis is feasible for uretero-ileal anastomosis with simple operation and good anastomosis formation.After further experimental verification,this technique is expected to be used in clinical practice.

In this study, bibliometric methods were used to systematically investigate the name and origin, the evolution of prescription composition, dose evolution, origin and processing method, decoction method, ancient application, modified application, modern application and other information of Huoxiang Zhengqisan. After research, Huoxiang Zhengqisan, also known as Huoxiang Zhengqitang, was first recorded in Taiping Huimin Hejijufang. The original formula is composed of 41.3 g of Arecae Pericarpium, 41.3 g of Angelicae Dahuricae Radix, 41.3 g of Perilla frutescens(actually Perillae Folium), 41.3 g of Poria, 82.6 g of Pinelliae Rhizoma, 82.6 g of Atractylodis Macrocephalae Rhizoma, 82.6 g of Citri Reticulatae Pericarpium(actually Citri Exocarpium Rubbum), 82.6 g of Magnoliae Officinalis Cortex, 82.6 g of Platycodonis Radix, 123.9 g of Pogostemonis Herba, and 103.25 g of Glycyrrhizae Radix et Rhizoma. In this formula, Magnoliae Officinalis Cortex is processed according to the specifications for ginger-processed products, Glycyrrhizae Radix et Rhizoma is processed according to the specifications for stir-fried products, and other herbs are used in their raw products. The botanical sources of the herbs are consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The above herbs are ground into a fine powder with a particle size passing through a No. 5 sieve. For each dose, take 8.26 g of the powdered formula, add 300 mL of water, along with 3 g of Zingiberis Rhizoma Recens and 3 g of Jujubae Fructus, and decoct until reduced to 140 mL. The decoction should be administered hot, with three times daily. To induce sweating, the patient should be kept warm under a quilt, and an additional dose should be prepared and taken if needed. This formula is traditionally used to relieve the exterior and resolve dampness, regulate Qi and harmonize the middle, which is mainly used to treat a series of diseases of digestive and respiratory systems. However, potential adverse reactions, including allergies, purpura and disulfiram-like reactions, should be considered during clinical use. Huoxiang Zhengqisan features a rational composition, extensive clinical application, and strong potential for further research and development.
