Precise Clinical Positioning of Chinese Patent Medicine in Paradigm of "Target Spectral Effect of Prescription"： A Case Study of Qizhi Tongluo Capsules / 中国实验方剂学杂志

The clinical value of Chinese patent medicine is the core direction of the development of the traditional Chinese medicine industry. The precise clinical positioning determines the way to prove the value of the drug， and is a key link to highlight the clinical value. This paper presented a case study of clinical positioning for Chinese patent medicine， namely Qizhi Tongluo capsules， and the key technical framework of precise clinical positioning of Chinese patent medicine， which was manifested as a comparison of prescription target spectral effect， discovery of core value of prescription， and confirmation of clinical positioning trial. The technical framework was designed to address a range of issues in the realm of precise clinical positioning. Before the clinical positioning trial， based on the multi-component， multi-target， and multi-phenotype data of prescription and clinical indication， the multi-omics network analysis technology was used to identify the core value of the traditional Chinese medicine varieties and predict the potential clinical advantages. Then， based on the predicted clinical advantages， reasonable efficacy indicators were selected， and the clinical efficacy was judged and verified by dynamic and flexible innovative clinical trials to improve the success rate of clinical positioning. This research paradigm integrates "omics technology" with "evidence-based" principles and follows the "precise evidence-based" concept. This research aims to provide a new strategy and method for the precise medication and positioning of Chinese patent medicine with traditional Chinese medicine characteristics after being put into the market and provide more technical thinking for traditional Chinese medicine to move towards precise medicine.

Comparison of two analysis methods of opioid consumption sum in medical institutions / 中国药房

OBJECTIVE To compare the similarities and differences of the two methods in analyzing the use of opioids in third grade class A medical institutions and provide a reference for the management of opioids in medical institutions. METHODS Two methods， Defined Daily Dose （DDD） and Oral Morphine Equivalent （OME）， were used to count the opioid prescription data of five comprehensive medical institutions of third grade class A （named H1-H5） in Shanxi province in 2020， calculate consumption sum of opioid， annual per capita consumption sum， patient cost burden and drug consumption sum ratio， compare the index results presented by the two analysis methods， and explore the application scenarios of the advantages of each of the two evaluation methods. RESULTS The ranking of consumption sum of opioid and patient cost burden calculated by the two methods was the same in the five sample medical institutions， but the ranking of per capita consumption sum was different. Taking the 5 medical institutions as a whole， the top 4 rankings of consumption sum ratio for each species of opioid compared by both methods were the same， i. e. remifentanil＞sufentanil＞oxycodone＞morphine. The ratio of remifentanil was close to 50%. When comparing the ranking of consumption sum ratio in each medical institution， the ranking calculated by the two methods was different for those medical institutions except for H1 medical institutions. The consumption sum ratio of fentanyl calculated by DDD method was significantly higher than that of OME method； whereas consumption sum ratio of remifentanil calculated by OME method was significantly higher than that of DDD method. Perioperative patients had the highest consumption sum ratio， about 50%. The consumption sum ratio of critically ill patients in H3 jwsydey@163.com medical institutions and inpatient patients with cancer pain and other patients in H5 medical institutions calculated by DDD method was significantly higher than that by OME method. There were differences in the order of cost burden of different types of patients calculated by two methods. CONCLUSIONS DDD method can accurately reflect the dosage of opioid drugs and facilitate the monitoring and management of the dosage； OME method can more reflect the analgesic effect and compare the cost burden of patients.

Three oral Chinese patent medicines for children with tic disorder: a rapid health technology assessment / 中国中药杂志

This study aims to comprehensively evaluate the clinical value of Shaoma Zhijing Granules(SZG), Changma Xifeng Tablets(CXT), and Jiuwei Xifeng Granules(JXG) in the treatment of children with tic disorder with the method of rapid health technology assessment(RHTA), which is expected to serve as a reference for medical and health decision-making and clinical rational use of drugs in children. To be specific, relevant articles were retrieved from eight databases and three clinical trial registry platforms. After the quality evaluation, rapid assessment was carried out from the dimensions of disease burden and unmet needs, technical characteristics, safety, efficacy and economy, and the results were analyzed and presented descriptively. A total of 22 articles(1 in English, 21 in Chinese) were screened out: 18 randomized controlled trials(RCTs) and 4 clinical controlled trials(CCTs). Among them, 5 were about the SZG(all RCTs) and 9 were on CXT(6 RCTs and 3 CCTs). The rest 8 focused on JXG(7 RCTs and 1 CCT). Moreover, the overall risk of bias for 94.40% RCTs was evaluated as "some concerns" and only one(5.60%) had high risk of bias. In terms of quality, the 4 CCTs scored 5-6 points(<7 points), suggesting low quality. SZG alone or in combination with tiapride has obvious advantages in improving traditional Chinese medicine syndromes and tic symptoms compared with tiapride alone, with the average daily cost of CNY 79.44-119.16. Compared with conventional western medicine or placebo, CXT alone or in combination with conventional western medicine can improve the total effective rate and alleviate tic symptoms, and the average daily cost is CNY 22.50-67.50. JXG alone or in combination with conventional western medicine can effectively relieve tic symptoms compared with conventio-nal western medicine or placebo, with the average daily cost of CNY 82.42-164.85. The adverse events related to the three Chinese patent medicines mainly occurred in the digestive, respiratory, and nervous systems, all of which were mild. In general, SZG, CXT, and JXG are effective for children with tic disorder. They have been approved to be used in this field, of which SZG was approved in 2019, with the most up-to-date research evidence and high-quality RCT in Q1 journals. However, the comparative analysis of the three was affected by many factors, which should be further clarified. Based on the large sample data available in multiple dimensions, a comprehensive comparative evaluation of the three Chinese patent medicines should be carried out, thereby highlighting the advantages and disadvantages of them and serving a reference for rational clinical use and drug supervision.

Better timing for HoLEP: a retrospective analysis of patients treated with HoLEP over a 10-year period with a 1-year follow-up / 亚洲男科学杂志(英文版)

The aim of this study was to explore the optimal timing of holmium laser enucleation of the prostate (HoLEP) in patients presenting benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). A retrospective analysis was conducted based on the perioperative and postoperative outcome data of 1212 patients who underwent HoLEP in Shanghai Ninth People's Hospital (Shanghai, China) between January 2009 and December 2018. According to the preoperative International Prostate Symptom Score (IPSS), all patients whom we analyzed were divided into Group A (IPSS of 8-18) and Group B (IPSS of 19-35). Peri- and postoperative outcome data were obtained during the 1-year follow-up. IPSS changes were the main postoperative outcomes. The postoperative IPSS, quality of life, peak urinary flow rate, postvoid residual, and overactive bladder symptom score (OABSS) improved significantly. The IPSS improved further in the group with severe LUTS symptoms, but the postoperative IPSS was still higher than that in the moderate LUTS group. OABSSs showing moderate and severe cases after follow-up were more frequent in Group B (9.1%) than in Group A (5.2%) (P < 0.05). There were no significant intergroup differences in the intraoperative American Society of Anesthesiologists or hospitalization expense scores, and the medication costs, as well as the total costs, were significantly higher in Group B. In this retrospective study, HoLEP was an effective treatment for symptomatic BPH. For patients with LUTS, earlier surgery in patients with moderate severity may result in a marginally better 12-month IPSS than that in men with severe symptoms.

Mechanism of n-butanol alcohol extract of Baitouweng Decoction in treatment of vulvovaginal candidiasis based on negative regulation of NLRP3 inflammasome via PKCδ/NLRC4/IL-1Ra axis / 中国中药杂志

This study aimed to explore the mechanism of n-butanol alcohol extract of Baitouweng Decoction(BAEB) in the treatment of vulvovaginal candidiasis(VVC) in mice based on the negative regulation of NLRP3 inflammasome via PKCδ/NLRC4/IL-1Ra axis. In the experiment, female C57BL/6 mice were divided randomly into the following six groups: a blank control group, a VVC model group, high-, medium-, and low-dose BAEB groups(80, 40, and 20 mg·kg~(-1)), and a fluconazole group(20 mg·kg~(-1)). The VVC model was induced in mice except for those in the blank control group by the estrogen dependence method. After modeling, no treatment was carried out in the blank control group. The mice in the high-, medium-, and low-dose BAEB groups were treated with BAEB at 80, 40, and 20 mg·kg~(-1), respectively, and those in the fluconazole group were treated with fluconazole at 20 mg·kg~(-1). The mice in the VVC model group received the same volume of normal saline. The general state and body weight of mice in each group were observed every day, and the morphological changes of Candida albicans in the vaginal lavage of mice were examined by Gram staining. The fungal load in the vaginal lavage of mice was detected by microdilution assay. After the mice were killed, the degree of neutrophil infiltration in the vaginal lavage was detected by Papanicolaou staining. The content of inflammatory cytokines interleukin(IL)-1β, IL-18, and lactate dehydrogenase(LDH) in the vaginal lavage was tested by enzyme-linked immunosorbent assay(ELISA), and vaginal histopathology was analyzed by hematoxylin-eosin(HE) staining. The expression and distribution of NLRP3, PKCδ, pNLRC4, and IL-1Ra in vaginal tissues were measured by immunohistochemistry(IHC), and the expression and distribution of pNLRC4 and IL-1Ra in vaginal tissues were detected by immunofluorescence(IF). The protein expression of NLRP3, PKCδ, pNLRC4, and IL-1Ra was detected by Western blot(WB), and the mRNA expression of NLRP3, PKCδ, pNLRC4, and IL-1Ra was detected by qRT-PCR. The results showed that compared with the blank control group, the VVC model group showed redness, edema, and white secretions in the vagina. Compared with the VVC model group, the BAEB groups showed improved general state of VVC mice. As revealed by Gram staining, Papanicolaou staining, microdilution assay, and HE staining, compared with the blank control group, the VVC model group showed a large number of hyphae, neutrophils infiltration, and increased fungal load in the vaginal lavage, destroyed vaginal mucosa, and infiltration of a large number of inflammatory cells. BAEB could reduce the transformation of C. albicans from yeast to hyphae. High-dose BAEB could significantly reduce neutrophil infiltration and fungal load. Low-and medium-dose BAEB could reduce the da-mage to the vaginal tissue, while high-dose BAEB could restore the damaged vaginal tissues to normal levels. ELISA results showed that the content of inflammatory cytokines IL-1β, IL-18, and LDH in the VVC model group significantly increased compared with that in the blank control group, and the content of IL-1β, IL-18 and LDH in the medium-and high-dose BAEB groups was significantly reduced compared with that in the VVC model group. WB and qRT-PCR results showed that compared with the blank control group, the VVC model group showed reduced protein and mRNA expression of PKCδ, pNLRC4, and IL-1Ra in vaginal tissues of mice and increased protein and mRNA expression of NLRP3. Compared with the VVC model group, the medium-and high-dose BAEB groups showed up-regulated protein and mRNA expression of PKCδ, pNLRC4, and IL-1Ra in vaginal tissues and inhibited protein and mRNA expression of NLRP3 in vaginal tissues. This study indicated that the therapeutic effect of BAEB on VVC mice was presumably related to the negative regulation of NLRP3 inflammasome by promoting PKCδ/NLRC4/IL-1Ra axis.

Tensor decomposition: new strategy for deciphering mechanism of precision medicine for same treatment of different diseases / 中国中药杂志

The aging society has led to a substantial increase in the number of clinical comorbidities. To meet the needs of comorbidity treatment, polypharmacy is widely used in clinical practice. However, polypharmacy has drawbacks such as treatment conflict. Same treatment of different diseases refers to treating different diseases with same treatment. Therefore, the principle of same treatment of different diseases can alleviate the problems caused by polypharmacy. Under the research background of precision medicine, it becomes possible to explore the mechanism of same treatment of different diseases and achieve its clinical application. However, drugs successfully developed in the past have revealed shortcomings in clinical use. To better interpret the mechanism of precision medicine for same treatment of different diseases, under the multi-dimensional attributes including dynamic space and time, omics was performed, and a new strategy of tensor decomposition was proposed. With the characteristics of complete data, tensor decomposition is advantageous in data mining and can fully grasp the connotation of precision treatment of different diseases with same treatment under dynamic spatiotemporal changes. This method is used for drug repositioning in some biocomputations. By taking advantage of the dimensionality reduction of tensor decomposition and integrating the dual influences of time and space, this study achieved accurate target prediction of same treatment of different diseases at each stage, and discovered the mechanism of precision medicine of same treatment for different diseases, providing scientific support for precision prescription and treatment of different diseases with same treatment in clinical practice. This study thus conducted preliminary exploration of the pharmacological mechanism of precision Chinese medicine treatment.

Objective:To establish a model of improving diagnostic capability in infiltration depth of colorectal cancer (CRC) with combining narrow band imaging system(NBI) and endoscopic ultrasonography (EUS).Methods:CRC patients who were treated in Chongqing Fifth People′s Hospital from April 2015 to March 2021 were selected retrospectively as the research objects. All patients were diagnosed by postoperative pathological diagnosis. In the end, a total of 288 CRC patients were included. Using the random number table method, the study subjects were divided into modeling group ( n=192) and verification group ( n=96) at a ratio of 2∶1. The patients′ general information, NBI and EUS examination results were collected; logistic regression was used to analyze the independent risk factors of CRC submucosal infiltration, and a model was built to predict the depth of CRC infiltration; receiver operating characteristic (ROC) was used to identify the diagnostic ability of model. The diagnostic efficacy of CRC submucosal infiltration was verified internally by the verification group. Results:In the modeling group, lymph node metastasis ( OR=6.492, 95% CI: 5.128-7.855, P<0.001), low tumor differentiation ( OR=2.736, 95% CI: 1.731-3.741, P<0.001) and tumor length ( OR=2.049, 95% CI: 1.524-2.574, P<0.001) were independent risk factors for submucosal infiltration in CRC patients; The nomograph model constructed according to the above independent risk factors had a strong diagnostic ability for the depth of submucosal infiltration of CRC, and was internally validated in the validation group. AUC values of the modeling group and the validation group were 0.945 (0.935-0.955) and 0.951 (0.942-0.961), respectively. Conclusions:The nomogram model established by the combination of endoscopic narrow band imaging technology and ultrasound endoscopy can diagnose the depth of CRC infiltration better.

Epigenetic regulation of microglia-mediated innate immune memory and neurological diseases / 生理学报

Microglia have the ability to mediate innate immune memory and can be reprogrammed by primary stimuli to enhance or inhibit the immune response of microglia to secondary stimuli. Inflammatory stimulation is an important factor for microglia to mediate innate immune memory. Single or repeated stimulation can induce microglia to form different phenotypes. Microglia-mediated innate immune response is involved in the regulation of immune memory. Enhancer modification is a key pathway of microglia epigenetic regulation, and the H3K27ac enhancer marker is closely related to immune training. TGF-β1 mediates the interaction between IL-10 and IL-1β, thereby influencing the microglial phenotype. Microglia glycolysis activity is increased after immune training, and oxidative phosphorylation is associated with immune tolerance. Innate immune memory is closely associated with neurodegenerative diseases, brain tumors, brain damage and psychosis. Further study on the mechanism of microglia-mediated innate immune memory is helpful to understand the occurrence and development of central nervous system diseases and provide new options for the treatment of central nervous system diseases.

Design of non-metallic crown for primary molars and analyzation of stress distribution: a finite element study / 中华口腔医学杂志

Objectives: To study the design of nonmetallic crowns for deciduous molars by means of computer aided design and to analyze the key parameters of the nonmetallic crowns of deciduous molars using finite element method. Methods: The three-dimensional model of a mandibular second primary molar was constructed by using a micro-CT system. The thickness of the crown was limited to 0.5 mm and four different crown shapes (chamfer+anatomic, chamfer+non-anatomic, knife edge+anatomic and knife edge+non-anatomic) were designed. Then, the crown shape was limited as chamfer+non-anatomic and five different thicknesses of the crown (0.50, 0.75, 1.00, 1.25, 1.50 mm) were designed, and three different materials, including polyetherketoneketone (PEKK), polymethylmethacrylate (PMMA) resin and resin-infiltrated ceramic, were applied to make the crown. Stress distribution and fatigue of each component of the model under vertical and oblique loadings were analyzed by using finite element method. Non-axial retention analysis was performed on chamfer+non-anatomic crowns, made of PMMA resin, with thicknesses of 0.50, 0.75, 1.00, 1.25 and 1.50 mm. Results: Among the four crown shape designs, the chamfer+non-anatomic type crown showed the lowest von Mises stress and the highest safety factor. By comparing three different materials, the resin-infiltrated ceramic group showed obvious stress concentration on the buccal edge of the crown and the PEKK group showed stress concentration in the adhesive layer. Results of non-axial retention analysis showed that the torques required by the crowns with five thicknesses at the same rotation angle were as follows: 4 856.1, 4 038.1, 3 497.3, 3 256.3 and 3 074.3 N⋅m, respectively. The comparison of areas of the adhesives fracture among groups were as follows: 0.5 mm group < 0.75 mm group < 1.00 mm group < 1.25 mm group < 1.50 mm group. Conclusions: In the design of nonmetallic crowns for primary molars, the edge of the crown should be designed as chamfer, the shape of the inner crown should be non-anatomical and the minimum preparation amount of the occlusal surface should be 1.00 mm. Among the three materials, PMMA resin, of which elastic modulus is similar to the dentin and the dental adhesive, might be the most suitable material for the crowns of primary molars.

In mild and moderate functional disorder patients, the muscle strength in flexion, extension and left and right flexion direction was greater, the difference was statistically significant (P <0.01). Conclusion: There is a negative correlation between cervical functional disorder and cervical muscle strength in office workers, suggesting that strengthening cervical muscle strength may be a way to improve cervical spine function.

Continuous monitoring of intracranial pressure and partial oxygen pressure of brain tissue in patients with severe traumatic brain injury after standard decompressive craniectomy and microscopic hematoma removal / 中国综合临床

Objective:To investigate the effect of continuous intracranial pressure (ICP) and brain oxygen partial pressure (PbtO 2) monitoring and guiding treatment after the application of standard large bone flap decompression and microhematoma removal in patients with severe traumatic brain injury (TBI). Methods:A retrospective analysis was done of 41 patients with TBI in Department of Neurosurgery in the Inner Mongolia People's Hospital from January 2018 to May 2020. Patients with Glasgow coma scale (GCS)<8 points were treatesd with microscopical removal of hematoma and contusion brain tissue and standard large bone flap decompression. Intraoperative intracranial pressure and brain tissue oxygen partial pressure monitoring probes were placed. Postoperatively, continuous intracranial pressure monitoring and partial oxygen pressure monitoring of brain tissue were performed, and target-based treatment under ICP and PbtO 2 monitoring was performed. According to the Glasgow Outcome (GOS) score after six months, patients were divided into a good outcome group (4-5 scores) and a poor outcome group (1-3 scores). There were 26 cases in good prognosis group and 15 cases in poor prognosis group. Linear regression analysis was used to further evaluate the relationship between PbtO 2, ICP and GOS score. The measurement data of normal distribution were compared by independent sample t-test. The counting data were expressed in cases (%), and the comparison between groups was adopted χ 2 inspection. The general linear bivariate Pearson correlation test was used. Results:The mean value of PbtO 2 (17.42±5.34) mmHg in the poor prognosis group was lower than that in the good prognosis group (24.65±5.61) mmHg, with statistical significance ( t=4.04, P<0.001). The mean value of ICP (22.32±3.45) mmHg in the poor prognosis group was higher than that (17.32±3.23) mmHg in the good prognosis group, with statistical significance ( t=4.15, P<0.001). Using PbtO 2 and ICP as independent variables and GOS score after 6 months as dependent variable, a regression equation was established ( Y=4.040 X+7.497; Y=-2.549 X+28.63). The mean value of PbtO 2 was positively correlated with GOS scores after 6 months in patients with severe head injury ( r=0.75, P<0.001). The mean value of ICP was negatively correlated with the prognosis of patients with severe head injury ( r=-0.87, P<0.001). Conclusion:The treatment guided by ICP combined with PbtO 2 monitoring is valuable in improving the prognosis of patients with severe traumatic brain injury after standard decompressive craniectomy, and may improve the prognosis 6 months after the injury.

Research progress in the application of chemical space in the field of Traditional Chinese Medicine / 国际中医中药杂志

Combined with the related research progress of the application of chemical space in the field of Traditional Chinese Medicine (TCM), the common database resources and calculation tools of chemical space research are summarized and analyzed. The compatibility law of chemical space in TCM prescriptions, the screening of effective ingredients of TCMs, and TCM compounds are summarized. It was found that the current studies mainly focus on the efficacy and multi-target studies of TCMs and TCM compound, among which there are more studies on osteoarthritis and rheumatoid arthritis. The existing studies have clarified the efficacy and targets of TCMs or TCM compound for diseases, but there is still a lack of a database on the main components of all TCMs and the efficacy and main targets of TCM compound. Therefore, there needs a new database for the main efficacy molecules and targets of TCMs.

Distribution Mechanism of Network Modules in Combined Treatment of Liver Cancer with Jiuwei Zhengxiao Granules / 中国实验方剂学杂志

ObjectiveTo explore the distribution mechanism of network modules in the combined treatment of liver cancer with Jiuwei Zhengxiao granules （JWZX） based on the analysis framework of module pharmacology. MethodThe cell experiment and the animal experiment were carried out to investigate the in vitro anti-liver cancer efficacy of JWZX of different concentrations and the effect on the survival time of H22 ascites tumor mice. By virtue of the analysis strategy of modular pharmacology，the distribution characteristics of nine Chinese drugs in the liver cancer disease network modules were investigated based on the constructed liver cancer disease network and module division by MCODE. In this study，the average degree （AD） of the nodes in the modules was used as an index to screen the main modules of the disease，and the intervention of the sovereign drugs，minister drugs，and assistant drugs on the main modules was explored. Finally，the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis was performed on the drug-acted modules by Metascape. ResultAs revealed by the cell experiment，JWZX could significantly inhibit the proliferation of H22 cells. The animal experiment demonstrated that the medium- and high-dose JWZX could significantly prolong the survival time of mice with H22 ascites tumor （P<0.05，P<0.01）. The distribution of targets of JWZX in the liver cancer disease network modules showed that JWZX interfered with tumor necrosis factor （TNF），epidermal growth factor receptor （EGFR），vascular endothelial growth factor A （VEGFA），transcription factor （JUN），tumor protein p53 （TP53），and other 26 targets and 8 modules. The sovereign drug Ginkgo Semen mainly intervened in modules 3 and 8，and the minister drugs such as Centipeda Herba jointly intervened in modules 1，3，5，8，10，and 12. Centipeda Herba and Phyllanthi Fructus intervened in module 7 and module 19 individually. Artemisiae Annuae Herba and other assistant drugs jointly intervened in modules 3，5，10，and 12. KEGG pathway enrichment analysis found that 135 pathways were enriched in 8 modules，and the pathway functions involved 12 categories including cancer，signal transduction，immune system，endocrine system，and amino acid metabolism. The functions of the four major modules involved cancer，signal transduction，and immune system. According to the results of literature verification，the key links of JWZX on the liver cancer disease network and the core mechanism were presumedly related to the inhibition of phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） and hypoxia-inducible factor-1 （HIF-1） signaling pathways，reduction of the immunosuppressive effect in the tumor microenvironment，and improvement of the anti-tumor immune response. ConclusionJWZX possesses pharmacological activity against liver cancer，and the therapeutic efficacy was achieved through the multiple targets，multiple modules，and multiple functions of drugs alone or in combination to intervene in the disease. The present study reduced the complexity of drug-disease target network analysis with module analysis strategy and explored the network module distribution mechanism of JWZX in the treatment of liver cancer，which provides a new idea for interpreting the complex mechanism of prescription compatibility.

Effects of plication procedures in special cases of Peyronie's disease: a single-center retrospective study of 72 patients / 亚洲男科学杂志(英文版)

General recommendations regarding surgical techniques are not always appropriate for all Peyronie's disease (PD) patients. Therefore, the purpose of this study was to investigate the effects of plication procedures in PD patients with severe penile curvature and the effects of early surgical correction in patients who no longer have progressive deformities. The clinical data from 72 patients who underwent plication procedures were analyzed in this study. Patients were divided into Groups A and B according to the curvature severity (≤60° or >60°) and Groups 1 and 2 according to the duration of disease stabilization (≥3 months or <3 months). At the 1-year follow-up, 90.0% (36/40) and 90.6% (29/32) patients reported complete penile straightening, and 60.0% (24/40) and 100.0% (32/32) patients reported penile shortening in Groups A and B, respectively. No curvature recurrence occurred in any patient, and no significant differences were observed in postoperative International Index of Erectile Function-Erectile Function domain (IIEF-EF), erectile pain, sensitivity, or suture knots on the penis whether such outcomes were grouped according to the curvature severity or the duration of stabilization. However, the duration from symptom onset to surgical management in Group 1 was significantly longer than that in Group 2 (mean ± standard deviation [s.d.]: 20.9 ± 2.0 months and 14.3 ± 1.2 months, respectively, P < 0.001). The present study showed that the plication procedures seemed to be an effective choice for the surgical treatment of PD patients with severe penile curvature. In addition, the early surgical treatment seemed to benefit those patients who already had no erectile pain and no longer exhibited progressive deformity.

Butyl alcohol extract of Baitouweng Decoction alleviates vulvovaginal candidiasis in mice by downregulating NLRP3 inflammasome and related signal pathways / 中国中药杂志

This study aims to explore the effect of butyl alcohol extract of Baitouweng Decoction(BAEB) on vulvovaginal candidiasis(VVC) in mice and to clarify the mechanism from Toll-like receptors(TLRs)/MyD88 and Dectin-1/Syk signal pathways and NLRP3 inflammasome. To be specific, female KM mice were randomized into control group(i.g., normal saline), model group, fluco-nazole group(i.g., 20 mg·kg~(-1)), and low-dose, medium-dose, and high-dose BAEB groups(i.g., 20, 40, and 80 mg·kg~(-1), respectively). VVC was induced in mice except the control group. After the modeling, administration began and lasted 7 days. The ge-neral conditions and body weight of mice were recorded every day. On the 1 st, 3 rd, 7 th, and 14 th after vaginal infection by Candida albicans, the fungal load in the vaginal lavage fluid of the mice was measured with the plate method, and the morphology of C. albicans in vaginal lavage fluid was observed based on Gram staining. After the mice were killed, vaginal tissues were subjected to hematoxylin-eosin(HE) staining and periodic acid-Schiff(PAS) staining for vaginal histopathological analysis. The content of cytokines in vaginal lavage fluid, such as interleukin(IL)-1β, IL-18, tumor necrosis factor-α(TNF-α), IL-6, and S100 a8, was determined by enzyme-linked immunosorbent assay(ELISA), and content of reactive oxygen species(ROS) in vaginal tissues by tissue ROS detection kit. The protein expression of NLRP3, ASC, caspase-1, Dectin-1, Syk, MyD88, TLR2, TLR4, and nuclear factor-κB(NF-κB) in vaginal tissues was detected by Western blot, and the levels and distribution of NLRP3, Dectin-1, Syk, MyD88, TLR2, and TLR4 in vaginal tissues were determined with the immunohistochemical method. The results show that BAEB can improve the general conditions of VVC mice, reduce the fungal load and C. albicans hyphae in vaginal secretion, decrease ROS content in vaginal tissues and content of cytokines in vaginal lavage fluid, and down-regulate the expression of NLRP3, ASC, caspase-1, Dectin-1, Syk, MyD88, TLR2, TLR4, and NF-κB in vaginal tissues. The above results indicate that BAEB exerts therapeutic effect on VVC mice by down-regulating the key proteins in the TLRs/MyD88 and Dectin-1/Syk signal pathways and NLRP3 inflammasome.

Originality and innovation of disciplinary development of traditional Chinese medicine / 中国中药杂志

Adhering to Chinese culture and philosophy, the development of traditional Chinese medicine(TCM) should be cooperative and open. TCM should learn from the achievements of ancient and modern scientific and technological civilization in human history and promote cultural exchange. TCM advocates unity, harmony, and interaction, and keeps going in a new information and digital era with Big Science and Extensive Health. The disciplinary development of TCM should embrace inheritance and innovation, and explore the scientific research and transformation of clinical experience. The dual attributes of science and humanity of TCM should be followed. In terms of education, "reading classics, acquiring clinical experience, and consulting experienced tutors" cannot be ignored. Underpinned by Xiang-thinking, TCM development should highlight the originality and learn from the failures of excessive westernization in the past with an inclusive attitude to forge through disciplines to the leading position.
