ABSTRACT

OBJECTIVE@#To investigate a Met-controlled allosteric module (AM) of neural generation as a potential therapeutic target for brain ischemia.@*METHODS@#We selected Markov clustering algorithm (MCL) to mine functional modules in the related target networks. According to the topological similarity, one functional module was predicted in the modules of baicalin (BA), jasminoidin (JA), cholic acid (CA), compared with I/R model modules. This functional module included three genes: Inppl1, Met and Dapk3 (IMD). By gene ontology enrichment analysis, biological process related to this functional module was obtained. This functional module participated in generation of neurons. Western blotting was applied to present the compound-dependent regulation of IMD. Co-immunoprecipitation was used to reveal the relationship among the three members. We used IF to determine the number of newborn neurons between compound treatment group and ischemia/reperfusion group. The expressions of vascular endothelial growth factor (VEGF) and matrix metalloproteinase 9 (MMP-9) were supposed to show the changing circumstances for neural generation under cerebral ischemia.@*RESULTS@#Significant reduction in infarction volume and pathological changes were shown in the compound treatment groups compared with the I/R model group (P<0.05). Three nodes in one novel module of IMD were found to exert diverse compound-dependent ischemic-specific excitatory regulatory activities. An anti-ischemic excitatory allosteric module (AM@*CONCLUSIONS@#AM

ABSTRACT

Ureteral artery fistula (UAF) is a rare complication after long-term indwelling of ureteral stent. In this study, two cases were presented. Both of them underwent pelvic tumor surgery and radiotherapy, and had a history of cutaneous terminal ureterostomy and long-term indwelling of ureteral stents. The first case, a 52-year-old female, was admitted to hospital because of intermittent bleeding from ureteral dermostomy for 1 week on April 2, 2020. CT examination revealed hematocele in the left upper urinary tract, and left nephrectomy was performed.However, bleeding still presented and the distal ureteral resection was performed at the same time, and partial ureteral was ligated. Postoperative diagnostic was ureteral artery fistula. After 8 months of follow-up, no recurrent bleeding presented. Another case, a 82-year-old male, was admitted to hospital because of bleeding at the ureteral dermostomy for an hour on June 15, 2020. Contrast enhanced CT examination revealed intersecting of the left ureter and common iliac artery, and interventional surgery was performed, by which UAF was diagnosed. Embolization of left internal iliac artery and stent implantation of common iliac artery and external iliac artery were performed intraoperatively. The bleeding stopped immediately after the operation, and there was no further bleeding during follow-up of 6 months.

ABSTRACT

Objective:To investigate the application of continuous intracranial pressure (ICP) combined with regional cerebral oxygen saturation (rScO 2) monitoring in patients with hypertensive intracerebral hemorrhage before and after operation of the removal hematoma through small bone window and the effect on the prognosis of patients. Methods:The clinical data of 37 patients with supratentorial hypertensive intracerebral hemorrhage admitted to the neurosurgical intensive care unit of the people′s Hospital of Inner Mongolia Autonomous Region from April 2018 to October 2020 were retrospectively analyzed.ICP monitoring and near infrared spectroscopy (NIRS) were used to monitor the intracranial pressure and rScO 2 concentration before and after the operation, and the changes of intracranial pressure and rScO 2 before and after the operation were analyzed.According to Glasgow Outcome Score (GOS), patients with GOS score>3 were classified as good prognosis group (21 cases), and those with GOS score ≤3 were classified as poor prognosis group (16 cases). Results:The postoperative intracranial pressure((15.80±6.70) mmHg)of patientswith hypertensive intracerebral hemorrhage was lower than that before operation((20.40±5.80) mmHg), and the difference was statistically significant( t=3.226, P=0.002). The postoperative rScO 2 ((62.31±3.85)% )of patientswith hypertensive intracerebral hemorrhage was higher than that before operation((59.73±3.13)%), and the difference was statistically significant( t=3.171, P=0.002). The decrease of intracranial pressure in patients with good prognosis((6.53±2.21) mmHg)was more obvious than that in patients with poor prognosis((4.24±2.30) mmHg). The concentration of rScO 2 increased in both groups.But in the group with good prognosis, the rScO 2 increased((3.99±2.34)%)was significantly higher than that in poor prognosis group((2.32±2.25)%). Six months after operation, there were significant differences in preoperative and postoperative intracranial pressure and rScO 2 between good prognosis group and poor prognosis group, and the difference was statistically significant( t=3.090, 2.176; P=0.004, 0.036). Conclusion:Small bone window evacuation of intracerebral hematoma can significantly reduce the concentration of intracranial pressure and increase the concentration of rScO 2 in patients with intracerebral hemorrhage.The changes of intracranial pressure and rScO 2 before and after operation have potential value in judging the prognosis of patients.

ABSTRACT

Objective:To observe the expression of glucose regulated protein 78 (GRP78) in glioma and its clinical value in evaluating clinical prognosis.Methods:A total of 163 patients with glioma who were surgically removed and confirmed after surgery in the People′s Hospital of Inner Mongolia Autonomous Region were collected from March 2012 to October 2015. Immunohistochemical staining was used to observe the expression of GRP78 in patients with different WHO grades of glioma. Chi square test was used to compare the expression of GRP78 in glioma patients with different age, gender and WHO grade. Whether COX regression analysis GRP78 can be used as an independent prognostic indicator was investigated. Time series test and Kaplan Meier analysis were used to analyze the survival time of patients with different GRP78 expression levels.Results:The expression of GRP78 was up-regulated in glioma, and the patients with high expression of GRP78 (positive expression/strongly positive expression) were more common in stage Ⅲ/Ⅳ than in stage Ⅰ/Ⅱ. The expression of GRP78 was not statistically significant in different age and gender groups ( P>0.05), but was statistically significant in different WHO stages ( P<0.01). GRP78 was an independent prognostic factor for glioma ( P = 0.045). The median survival time of patients with glioma was 28 months (95% CI 37.594 to 47.046), of which the survival time of patients with high expression of GRP78 was 15 months (95% CI 12.922 to 40.801); the survival time of patients with low expression of GRP78 was 35 months (95% CI 39.807 to 51.352), and the difference was statistically significant ( P<0.01). The survival time of patients with high expression of GRP78 was significantly shorter than that of patients with low expression of GRP78 ( χ2 = 13.588, P<0.01). Conclusions:The expression level of GRP78 in glioma is significantly increased; high expression of GRP78 is more common in Ⅲ/Ⅳ glioma, and GRP78 can be used as an effective index to evaluate the poor prognosis of glioma.

The clinicopathological data of 2 female patients who underwent LARH via Laennec approach in the First Affiliated Hospital of Kangda College of Nanjing Medical University from May to July 2020 were collected. The two patients were 51 and 57 years old, respectively. Observation indicators: (1) surgical situations; (2) postoperative situations and follow-up. Follow-up using outpatient examination and telephone interview was conducted to detect post-operative survival and tumor recurrence of patients up to December 2020. Count data were repre-sented as absolute numbers.Results:(1) Surgical situations: 2 patients successfully underwent LARH via Laennec approach, without conversion to open surgery. The operation time was 180 minutes and 185 minutes, and the volume of intraoperative blood loss was 200 mL and 400 mL, respectively. No blood transfusion or gastrointestinal decompression was performed in either patient. (2) Postoperative situations and follow-up: 2 patients began to take liquid diet on the first day and out-of-bed activities on the postoperative second to third day. There was no postoperative bile fistula or bleeding, but different degrees of peritoneal and pleural effusion occurred to the 2 patients after operation. One case was improved after right-sided thoracentesis and chest tube drainage due to dyspnea, and the other case was cured after conservative therapy. There was no perioperative death. The duration of postoperative hospital stay of 2 patients was 13 days and 11 days, respectively. Results of pathological examination showed 1 case of hepatic hemangioma and 1 case of primary liver cancer, respectively. The Laennec capsule was observed on the hepatic vein branches of segment Ⅴ, Ⅵ, Ⅶ, Ⅷ, and the gap existed between the Laennec capsule and the hepatic vein. Two patients were followed up for 7 months and 5 months,respectively. They survived during the follow-up,without tumor recurrence.Conclusion:It is safe and feasible to perform LARH by Laennec approach.

ABSTRACT

Tsaoko Fructus is a type of food with the homology of medicine and food,and has a long history of cultivation and application in China. With the deepening of the development and utilization of Tsaoko Fructus,its economic value has appeared obviously,and relevant industries have great potential,with an important role in poverty alleviation in mountainous areas. However,the plants source of Tsaoko Fructus are confused in the process of actual production and resource utilization,and there is a lack of systematic report about the origin of varieties and medicinal history. The paper focused on a textual research for its names,plant sources,changes of the genuine producing areas and traditional efficacy through consulting the herbal works and the analysis of modern literature. The results showed that the medicine of Tsaoko Fructus was first recorded in ancient literatures of the Song dynasty,and there were many aliases and synonyms of the herb, with a great difference between ancient and modern times. In modern records,the medicinal alias names such as Hongcaoguo,Tucaoguo,Caoguoren are similar with the Chinese name of Caoguo,but they are not the same kind of plant and shall be distinguished. In the Ming dynasty,variety and source of the herb was complicated,and it was often recorded as the same class of medicinal materials with Amomi Fructus Rotundus and Alpiniae Katsumadai Semen,until it was listed as a class of medicinal material and distinguished from confounding medicines in the Qing Dynasty. The prescriptions containing Tsaoko Fructus include Caoguoyin,Caoguosan,Caoguowan,Caoguoshushui. Tsaoko Fructus could be used as medicine with peel or only kernel according to different diseases,and mainly processed with water or wine. In addition,there are other processing methods,such as frying,salt-processing, ginger- processing,simmering flour. Ancient literatures have basically the same records on properties,efficacies and indications of Tsaoko Fructus,considering it was warm in nature with the effect in relieving vomiting,eliminating food,intercepting malaria,expelling phlegm. This study provided a theoretical basis for its origin,quality control and resource development and utilization.

ABSTRACT

Cardiovascular and cerebrovascular diseases are one of the major diseases endangering human health, and its morbidity and mortality are still in the rising stage in our country. Traditional Chinese medicine (TCM) injections play an important role in the prevention and treatment of cardiovascular and cerebrovascular diseases due to their advantages of rapid onset, remarkable curative effect, and convenient use. Among them, Danhong injection (DHI), a Chinese medicine injection for promoting blood circulation and removing blood stasis, is widely used in the clinical treatment of cardio-cerebrovascular diseases. DHI is composed of Salviae Miltiorrhizae Radix et Rhizoma (Danshen in Chinese) and Carthami Flos (Honghua in Chinese), and mainly contains phenolic acids, tanshinones and flavonoids. A large number of studies have shown that DHI has a significant effect in the treatment of ischemic cardio-cerebrovascular diseases, is a representative drug of co-therapy of brain and heart of TCM, its pharmacological effects related to many aspects such as anti-inflammatory, anti-oxidation, anti-coagulation. At the same time, Other studies have also explained the protective effects of DHI on cardiovascular and cerebrovascular diseases through the overall regulation and intervention of multiple targets and pathways. However, DHI has a wide range of clinical applications, there are still many unknown pharmacological effects to be further explored. Therefore, this article summarizes the current researches on the chemical components of DHI, the multi-target and multi-path pharmacological mechanisms of DHI in the treatment of cardiovascular and cerebrovascular diseases, and introduces the latest pharmacological research progress, so as to provide theoretical guidance for clinical rational drug use and subsequent in-depth research.

ABSTRACT

Polygonati Rhizoma was first recorded in Mingyi Bielu(《名医别录》) as both medicine and food due to its high edible and medicinal values.However,there is no systematic textual research on its use as medicine and food. Polygonati Rhizoma and Polygonati Odorati Rhizoma show similar morphology,so they are often confused.Clematis apiifolia and Polygonatum odoratum are often regarded as the original plants of Polygonati Odorati Rhizoma. By reviewing the related records in Chinese herbal books of the past dynasties,this paper aimed to clarify the relationship between Polygonati Rhizoma,C.apiifolia and P.odoratum,trace the historical evolution of Polygonati Rhizoma as medicine and food from the name,harvesting and processing,property,flavor and meridian tropism,efficacy and indications,edible and medicinal records,and contraindications,and summarize its application in ethnic medicine,in order to inherit and develop the ethnic medicine. The findings demonstrated that the name of Polygonati Rhizoma and its synonyms were derived from its pictogram,function,and place of origin,containing a wealth of myth implication and Taoism thought.Polygonati Rhizoma,C.apiifolia and P.odoratum are three species,different from the conclusions in previous textual research. The seedlings,flowers,seeds,and rhizomes of Polygonati Rhizoma all could be used for edible and medicinal purposes,with its edible records exceeding the medicinal records. There were 22 medical books from the ethnic minority groups such as The Annals of National Medicine in Yunnan,Zhongguo Minzu Yaozhi Yao,and Dictionary of Chinese Ethnic Medicine recording the knowledge and application of 12 species in Polygonatum by 26 ethnic minorities.Due to their different living environments,lifestyles,and cultural customs,ethnic minorities have formed their unique medical cultures.

ABSTRACT

Objective To evaluate the impact of water pollutants, water levels and meteorological factors on the Oncomelania hupensis density in Eastern Dongting Lake regions, so as to provide insights into schistosomiasis control. Methods O. hupensis snails were surveyed using a systematic sampling method in snail-infested marshlands in Eastern Dongting Lake regions from 2007 to 2014, and data pertaining to water pollutants, water levels and meteorological factors were collected. The duration of submergence and the date of the start of submergence were calculated. The snail density and its influencing factors were descriptively analyzed, and a linear mixed model was generated to examine the impacts of variables on the snail density. In addition, smooth curves were fitted to investigate the relationship between snail density and variables. Results The snail density appeared a fluctuation in Eastern Dongting Lake regions during the period from 2007 to 2014, with the highest density on October, 2010 (52.79 snails/0.1 m2) and the lowest density on January 2009 (2.15 snails/0.1 m2). Linear mixed-model analysis showed that permanganate index, total phosphorus and the date of the start of submergence affected the snail density (t = 6.386, −2.920 and −3.892, all P values < 0.01). Smooth curve analysis revealed that the associations of the snail density with the permanganate index and total phosphorus appeared an approximately quadratic curve. After the end of April, the earlier date of the start of submergence resulted in a higher snail density. Conclusion Permenganate index, total phosphorus and the date of the start of submergence affect the O. hupensis snail density in Eastern Dongting Lake regions.

ABSTRACT

Although there is guidance from different regulatory agencies, there are opportunities to bring greater consistency and stronger applicability to address the practical issues of establishing and operating a data monitoring committee (DMC) for clinical studies of Chinese medicine. We names it as a Chinese Medicine Data Monitoring Committee (CMDMC). A panel composed of clinical and statistical experts shared their experience and thoughts on the important aspects of CMDMCs. Subsequently, a community standard on CMDMCs (T/CACM 1323-2019) was issued by the China Association of Chinese Medicine on September 12, 2019. This paper summarizes the key content of this standard to help the sponsors of clinical studies establish and operate CMDMCs, which will further develop the scientific integrity and quality of clinical studies.

ABSTRACT

Surgical correction can be considered for treating patients with a chronic phase of Peyronie's disease (PD) and persistent penile curvature. In clinical practice, some patients pay too much attention to surgical complications and refuse the recommended feasible surgical types. Meanwhile, they require operations according to their preferences. This study aimed to evaluate the effects of patients' own choice of surgical type on postoperative satisfaction. This retrospective study analyzed data from 108 patients with PD who underwent surgical correction according to doctors' recommendations or patients' own demands. The objective and subjective surgical outcomes were assessed. Patients' understanding of the disease was analyzed using a questionnaire survey. Objective measurements of surgical outcomes, including penile straightening, penile length, and sexual function, in patients who received the recommended surgery, were similar to those in patients who did not accept the recommended surgery. However, subjective evaluations, including erectile pain, discomfort because of nodules on the penis, and decreased sensitivity in the penis, were more obvious in patients who did not follow doctors' recommendations. In addition, a questionnaire survey showed that understanding PD and the purpose of surgery of patients who did not follow doctors' advice were inappropriate, as they did not conform to the principle of treatment. The present study showed that surgical correction seemed to be an objectively effective option in the management of patients in the stable chronic phase of PD. Low patient satisfaction might be related to patients' lack of correct understanding of the disease and its treatment strategy as well as unrealistic expectations.

ABSTRACT

The aim of this paper was to investigate the effect of berberine hydrochloride on the cell wall integrity of Candida albicans hypha. The minimal inhibitory concentration(MIC) of berberine hydrochloride against clinical and standard C. albicans strains was detected by micro liquid-based dilution method; the effect of berberine hydrochloride on the colony formation of C. albicans SC5314 was investigated by spot assay; the effect of berberine hydrochloride on the metabolism of C. albicans SC5314 hypha was checked by XTT reduction assay, and the viability of C. albicans SC5314 hypha was tested by fluorescent staining assay. The effect of berberine hydrochloride on the morphology of C. albicans SC5314 hypha was examined by scanning electron microscope. The changes in the cell wall of C. albicans SC5314 hypha after berberine hydrochloride treatment were detected by transmission electron microscopy. The effect of berberine hydrochloride on β-glucan from C. albicans SC5314 was detected by flow cytometry. The effect of berberine hydrochloride on hypha-specific gene ECE1 and β-glucan synthase genes FKS1 and FKS2 in C. albicans was examined by qRT-PCR. The results showed that berberine hydrochloride showed a strong inhibitory effect on both clinical and standard strains of C. albicans, and the MIC was 64-128 μg·mL~(-1). Spot assay, XTT redunction assay and fluorescent staining assay showed that with the increase of berberine hydrochloride concentration, the viability of C. albicans SC5314 gradually decreased. The transmission electron microscopy scanning assay showed that this compound could cause cell wall damage of C. albicans. The flow cytometry analysis showed the exposure degree of C. albicans β-glucan. The qRT-PCR further showed that berberine hydrochloride could significantly down-regulate hypha-specific gene ECE1 and β-glucan synthase-related gene FKS1 and FKS2. In conclusion, this compound can down-regulate C. albicans and β-glucan synthase-related gene expressions, so as to destroy the cell wall structure of C. albicans, expose β-glucan and damage the integrity of the wall.

ABSTRACT

Ma-Xing-Shi-Gan Decoction is a classic prescription. However, the interaction among multiple components of the decoction and the change of phase state are not clear. Moreover, the relationship between the physical phase state aggregated by multiple components and the efficacy still needs to be studied. In this study, we monitored the particle size changes of Ma-Xing-Shi-Gan Decoction in real time. Then we isolated different phase states by centrifugation, analyzed their composition distribution and tested their antibacterial activity. We added chemical interference agents to investigate the interaction of multi-component physical phase states accompanied by the observation of particle size change and morphology. We also studied the correlation between antibacterial activity and physical structure of phase states. The results showed during boiling process the degree of hybridization of particles was decreased and the particle size distribution was narrowed and stabilized at 170 nm. The distribution of organic and inorganic components was heterogeneous among different phase states. S-13500, supernatant isolated by 13 500 ×g centrifugation, constituted by ephedrine, amygdalin, glycyrrhizic acid and inorganic components Ca, K, Mg, etc., had the strongest antibacterial activity. The molecular interaction force in the active physical phase state was mainly hydrophobic and hydrogen bond. The destruction of the interaction force will lead to the change of phase structure and the decrease of antibacterial activity in vitro and in vivo. This study confirms that, in the boiling process of the Ma-Xing-Shi-Gan Decoction, the chemical components interweave and interact to form new physical phase states, leading to heterogeneous distribution of components. The antimicrobial activity of the active phase depends on both chemical composition and physical structure, which provides a direct evidence for the physical basis of the efficacy of traditional Chinese medicine.

ABSTRACT

Objective:To investigate the effects of continuous monitoring intracranial pressure (ICP) and brain oxygen partial pressure (PbtO 2) on the prognosis of patients with severe craniocerebral injury. Methods:A prospective randomized controlled trial was conducted. Seventy patients with severe craniocerebral injury with a Glasgow coma score (GCS) 4-8 admitted to the neurosurgical intensive care unit (NICU) of the People's Hospital of Inner Mongolia Autonomous Region from January 2017 to May 2020 were enrolled, and they were divided into ICP monitoring group and ICP+PbtO 2 monitoring group by random number table. Patients in ICP monitoring group received ICP monitoring and were given traditional treatment of controlling ICP and cerebral perfusion pressure (CPP), the therapeutic target was ICP < 20 mmHg (1 mmHg = 0.133 kPa) and CPP > 60 mmHg. Patients in ICP+PbtO 2 monitoring group were given ICP and PbtO 2 monitoring at the same time, and oxygen flow was adjusted on the basis of controlling ICP and CPP to maintain the PbtO 2 > 20 mmHg, and the therapeutic target of ICP and CPP was the same as the ICP monitoring group. ICP and PbtO 2 values were recorded during monitoring in the two groups, the results of CPP, GCS and arterial blood gas analysis were recorded, and the prognosis at 3 months and 6 months after injury was compared by Glasgow outcome scale (GOS) score between the two groups. GOS score > 3 was considered as good prognosis. Kaplan-Meier survival curve was drawn, and the 3-month and 6-month cumulative survival rates of the two groups were analyzed. Linear regression analysis was used to further evaluate the relationship between PbtO 2 and GOS score. Results:Finally, a total of 70 patients with severe craniocerebral injury were enrolled in the analysis, 34 patients received ICP combined with PbtO 2 monitoring and guided therapy, and 36 patients received ICP monitoring alone. The average ICP of ICP+PbtO 2 monitoring group was significantly lower than that of ICP monitoring group (mmHg: 13.4±3.2 vs. 18.2±8.3, P < 0.01). Although the CPP in both groups was great than 60 mmHg, the average CPP of ICP+PbtO 2 monitoring group was significantly higher than that of ICP monitoring group (mmHg: 82.1±10.5 vs. 74.5±11.6, P < 0.01). No significant difference was found in average GCS score or arterial partial pressure of carbon dioxide (PaCO 2) between the ICP+PbtO 2 monitoring group and ICP monitoring group [GCS score: 5.3±2.3 vs. 5.2±2.2, PaCO 2 (mmHg): 33.5±4.8 vs. 32.6±5.2, both P > 0.05]. The average arterial partial pressure of oxygen (PaO 2) of ICP+PbtO 2 monitoring group was obviously higher than that of ICP monitoring group (mmHg: 228.4±93.6 vs. 167.3±81.2, P < 0.01). Compared with the ICP monitoring group, the good outcome rates of 3 months and 6 months after injury in the ICP+PbtO 2 monitoring group were significantly higher (3 months: 67.6% vs. 38.9%, 6 months: 70.6% vs. 41.7%, both P < 0.05). Kaplan-Meier survival curve showed that the 3-month and 6-month cumulative survival rates of ICP+PbtO 2 monitoring group were significantly higher than those of ICP monitoring group (3 months: 85.3% vs. 61.1%, Log-Rank test: χ2 = 5.171, P = 0.023; 6 months: 79.4% vs. 55.6%, Log-Rank test: χ2 = 4.511, P = 0.034). Linear regression analysis showed that PbtO 2 was significantly correlated with GOS score at 3 months and 6 months after injury in patients with severe craniocerebral injury ( r values were 0.951 and 0.933, both P < 0.01). Conclusions:PbtO 2 compared with ICP monitoring guiding therapy is valuable in improving the prognosis of patients with severe craniocerebral injury. It can improve the prognosis at 3-6 months after injury.

ABSTRACT

Monocarboxylic acid transporter 1 (MCT1) maintains axonal function by transferring lactic acid from oligodendrocytes to axons. Subarachnoid hemorrhage (SAH) induces white matter injury, but the involvement of MCT1 is unclear. In this study, the SAH model of adult male Sprague-Dawley rats was used to explore the role of MCT1 in white matter injury after SAH. At 48 h after SAH, oligodendrocyte MCT1 was significantly reduced, and the exogenous overexpression of MCT1 significantly improved white matter integrity and long-term cognitive function. Motor training after SAH significantly increased the number of ITPR2

ABSTRACT

Objective@#To evaluate the safety and clinical efficiency of holmium laser enucleation of the prostate (HoLEP) in the treatment of small-volume BPH (SBPH) complicated by severe lower urinary tract symptoms (LUTS).@*METHODS@#We retrospectively analyzed the clinical data on 82 cases of SBPH with severe LUTS treated by HoLEP from January 2017 to December 2018. The patients were aged (65.5 ± 7.6) years, with a mean prostate volume of <40 ml, a total IPSS of 24.8 ± 4.6, a QOL score of 5.2 ± 0.8, the maximum urinary flow rate (Qmax) of (7.6 ± 3.7) ml/s, and a mean PSA level of (1.8 ± 1.4) μg/L.@*RESULTS@#All the operations were successfully completed, the mean operation time averaging (30.2 ± 5.0) min, enucleation time (26.7 ± 5.6) min and comminution time (3.5 ± 1.1) min, and the enucleated tissue weighing (20.3 ± 4.9) g. After surgery, the bladders were irrigated for (3.5 ± 1.9) h, with (3.0 ± 1.7) L of rinse solution, and catheterization lasted (24.8 ± 9.7) h. Histopathology revealed moderate or severe lymphocytic infiltration in 69 cases (84.1%). At 6 months after operation, significant improvement was observed in the IPSS, QOL, Qmax and PSA level compared with the baseline (P < 0.05). To date, no urethral stricture-related reoperation was ever necessitated.@*CONCLUSIONS@#HoLEP is safe and effective for the treatment of SBPH complicated by severe LUTS and can be employed after adequate preoperative evaluation of the patient.《.

ABSTRACT

This study explored the mechanism of Sanhuang Decoction(SHD) in treating dextran sulfate sodium(DSS)-induced ulcerative colitis(UC) in mice with Candida albicans(Ca) colonization via high-throughput transcriptome sequencing. Specifically, the animal model was established by oral administration of 3.0% DSS for 7 days followed by intragastrical administration of Ca suspension at 1.0 × 10~8 cells for 4 days and then the mice were treated with SHD enema for 7 days. Afterwards, the general signs were observed and the disease activity index(DAI) was recorded every day. After mice were sacrificed, colon length and colon mucosa damage index(CMDI) were determined and the histomorphology was observed with the HE staining method. The fungal loads of feces were detected with the plate method. Anti-saccharomyces cerevisiae antibody(ASCA) and β-1,3-glucan in serum, and TNF-α, IL-1β, and IL-6 in serum and colon were detected by ELISA. High-throughput RNA sequencing method was adopted to identify transcriptome of colon tissues from the control, model and SHD(15.0 g·kg~(-1)) groups. Differentially expressed genes(DEGs) among groups were screened and the GO and KEGG pathway enrichment analysis of the DEGs was performed. The expression levels of NLRP3, ASC, caspase-1, and IL-1β genes related to the NOD-like receptor signaling pathway which involved 9 DEGs, were examined by qRT-PCR and Western blot. The results demonstrated that SHD improved the general signs, decreased DAI and Ca loads of feaces, alleviated colon edema, erosion, and shortening, and lowered the content of β-1,3-glucan in serum and TNF-α, IL-1β, and IL-6 in serum and colon tissues of mice. Transcriptome sequencing revealed 383 DEGs between SHD and model groups, which were mainly involved in the biological processes of immune system, response to bacterium, and innate immune response. They were mainly enriched in the NOD-like signaling pathway, cytokine-cytokine interaction pathway, and retinol metabolism pathway. Moreover, SHD down-regulated the mRNA and protein levels of NLRP3, caspase-1, and IL-1β. In a word, SHD ameliorates DSS-induced UC in mice colonized with Ca, which probably relates to its regulation of NOD-like receptor signaling pathway.

ABSTRACT

The present study aims to investigate the effects of the main components(aesculin, berberine hydrochloride, and anemoside B4) in the butyl alcohol extract of Baitouweng Decoction(BAEB) on the chemotaxis of neutrophils induced by dimethyl sulfoxide(DMSO). HL60 cells were cultivated in RPMI-1640 complete medium, and transferred into a 6-well plate(2 × 10~5 per mL) with 4 mL in each well, followed by incubation with DMSO at 1.3% for five days. The morphologic changes of cells were observed under an inverted microscope. The CD11 b expression after DMSO induction was analyzed by flow cytometry. The effects of aesculin, berberine hydrochloride, and anemoside B4 on the cell proliferation and migration were detected by CCK8 assay and Transwell assay, respectively. The effects of the main components on the production and polarization of F-actin protein were also examined by flow cytometry and laser confocal microscopy. PI3 K/Akt signaling pathway was checked by Western blot. As revealed by the results, neutrophil-like HL60 cells were observed after DMSO induction. The CD11 b expression in these cells increased significantly as indicated by the flow cytometry. Additionally, 100 μg·mL~(-1) aesculin, 8 μg·mL~(-1) berberine hydrochloride, and 80 μg·mL~(-1) anemoside B4 were potent in inhibiting the migration of neutrophils and reducing F-actin expression. Berberine hydrochloride was verified to be capable of diminishing phosphorylated PI3 K/Akt protein expression. The findings indicate that aesculin, anemoside B4, and especially berberine hydrochloride in the BAEB can inhibit the chemotaxis of neutrophils, which is possibly achieved by the inhibition of F-actin and PI3 K/Akt signaling pathway.
