Nerve decompression surgery for combined sacral plexus nerve injury through the lateral-rectus approach after sacral fracture fixation / 中华创伤骨科杂志

Objective:To investigate the efficacy and safety of nerve decompression surgery through the lateral-rectus approach for sacral plexus nerve injury after sacral fracture fixation.Methods:A retrospective study was conducted to analyze the 10 patients with combined sacral plexus nerve injury after sacral fracture fixation who had been admitted to Department of Orthopedics, Xiangya Hospital between May 2022 and May 2023. There were 2 males and 8 females with an age of 16.5 (15.0, 26.3) years. At the time of injury, the patients had been clearly diagnosed as sacral fracture combined with sacral plexus nerve injury. By the Denis classification of sacral fractures: 7 cases of type Ⅱ and 3 cases of type Ⅲ; sacral plexus nerve injury sites: 1 case of L 4, 8 cases of L 5, 7 cases of S 1, and 2 cases of S 2. All of them were treated with reduction and internal fixation via the posterior approach within 2 weeks after injury, but after surgery their manifestations of sacral plexus nerve injury still persisted which were confirmed by CT, magnetic resonance imaging and neuromuscular electromyography. Therefore, at (4.0±2.3) months after internal fixation, all patients were treated with nerve decompression surgery through the lateral-rectus approach. The operative time, intraoperative bleeding, length of hospitalization, Gibbons nerve damage score and neurological recovery at the last follow-up were recorded. Results:In the 10 patients, the operative time was (112.0±21.5) min, intraoperative bleeding (215.0±91.3) mL, and length of hospitalization 7.0 (6.0, 8.5) d. Intraoperatively, sacral plexus nerve compression was found in 9 cases (6 cases of nerve compression and pulling due to fracture displacement, 3 cases of nerve entrapment due to soft tissue scar adhesion), and 1 case of nerve root avulsion injury. No other intraoperative complications occurred. The 10 patients were followed up for (9.2±2.3) months after surgery. At the last follow-up, the Gibbons score for the 10 patients improved from preoperative 3.0 (3.0, 3.3) points to 1.0 (1.0, 2.0) point, and their British Medical Research Council (BMRC) nerve injury grading was improved from the preoperative grade 0.0 (0.0, 1.3) to grade 3.5 (2.8, 4.0) (1 case of M5, 4 cases of M4, 4 cases of M3, and 1 case of M2).Conclusion:The lateral-rectus approach is effective and safe for exploration and decompression of the sacral plexus nerve in patients combined with sacral plexus nerve injury despite sacral fracture fixation.

Promoting Reform of Talent Evaluation Based on China Clinical Cases Library of Traditional Chinese Medicine / 中国实验方剂学杂志

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

Expert Consensus on Clinical Diseases Responding Specifically to Traditional Chinese Medicine： Pulmonary Nodules / 中国实验方剂学杂志

In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

The clinical efficacy of robot-assisted internal fixation with sacroiliac screws for posterior pelvic ring fractures: a meta-analysis / 中华骨科杂志

Objective:To compare the clinical efficacy of robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures.Methods:China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Medical Journal Full-text Database, PubMed, Web of Science and ScienceDirect were searched for literature on robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures. The search time was from the establishment of each database to March 2023. Meta-analysis was performed on the included literature. The random-effects model was used when the heterogeneity between groups was large, and the fixed-effects model was used when the heterogeneity between groups was small.Results:A total of 15 studies were included in the meta-analysis, including 465 patients in the robot-assisted group and 396 patients in the fluoroscopy-assisted group. Meta-analysis showed that the number of fluoroscopies [ SMD=-3.12, 95% CI (-4.34, -1.89), P<0.001], the number of guide pin adjustments [ SMD=-3.75, 95% CI (-6.77, -0.72), P=0.015], intraoperative blood loss [ SMD=-0.83, 95% CI (-1.18, -0.49), P<0.001], and operative time [ SMD=-2.59, 95% CI (-4.11, -1.08), P<0.001] were smaller than those in the fluoroscopy-assisted group. The rate of excellent screw implantation [ OR=10.13, 95% CI (3.67,27.98), P<0.001] of the robot-assisted was larger than the fluoroscopy-assisted group. There was no significant difference in Majeed functional score [ SMD=0.28, 95% CI (-0.0003, 0.55), P=0.050] and fracture healing time [ SMD=-0.14, 95% CI (-0.46, 0.17), P=0.367] between the two groups. Conclusion:Robot-assisted percutaneous sacroiliac screw fixation for posterior pelvic ring fractures has the advantages of less fluoroscopy, less guide pin adjustment, less intraoperative blood loss, shorter operation time, and higher rate of excellent screw position. However, there is no difference in Majeed score and fracture healing time between robot-assisted percutaneous sacroiliac screw fixation and fluoroscopy-assisted percutaneous sacroiliac screw fixation.

Radix Tetrastigme Polysaccharide Promotes Antitumor Immune Response in Lewis Lung Cancer Mice / 中国肺癌杂志

BACKGROUND@#Lung cancer has a high incidence and mortality rate, but the treatment of lung cancer still lacks low toxicity and efficient anti-tumor drugs. Polysaccharide from radix tetrastigme has development value in anti-tumor treatment methods. This study was to observe the effect of polysaccharide from radix tetrastigme on immune response of Lewis lung cancer mice and explore its molecular mechanism.@*METHODS@#Lewis lung cancer mouse models were established and randomly grouped. The spleen polypeptide group was intragastric with 50 mg/kg spleen polypeptide, and the radix tetrastigme polysaccharide low, medium and high dose groups were intragastric with 62.5, 125 and 250 mg/kg radix tetrastigme polysaccharide, respectively, and the model group and the control group were intragastric with equivolume normal saline. Tumor formation and metastasis were compared. Haematoxylin-eosin (HE) staining was used to observe the pathological changes of tumor cells. Macrophage phagocytosis, apoptosis, M1/M2 polarization, T cell subsets and cytokine levels in peripheral blood were detected by flow cytometry. The proliferation activity of macrophages was detected by methyl thiazolyldiphenyl tetrazolium (MTT) assay. Dendritic cell (DC) antigen presenting function was detected by chlorophenol red-β-D-galactopyranoside (CPRG) method. Tumor tissue differentiation antigen cluster 47 (CD47) mRNA and protein expression and macrophage signal regulatory protein α (SIRRP α) expression were detected by real time quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB).@*RESULTS@#The tumor inhibition rates and anti-metastasis rates in the 3-dose radix tetrastigme polysaccharide group and the spleen polypeptide group were higher than those in the model group, and the pathological injury of tumor tissue were severer, and the positive rate of phagocytosis of ink by macrophages and the efficiency of phagocytosis of tumor cells were increased; the apoptosis rate of macrophages was decreased; the proliferation activity of macrophages, polarization ratio of macrophages to M1 type, DC antigen presenting ability, CD4+, CD4+/CD8+ levels were increased; the level of serum tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and the expression of tumor tissue CD47, macrophage SH2-containing protein tyrosine phosphatase 1 (SHP-1), SH2-containing protein tyrosine phosphatase 2 (SHP-2), and phosphorylation signal regulatory protein α (p-SIRPα) were decreased, and the differences were statistically significant (P<0.05). There were no significant differences in the above indexes between low-dose radix tetrastigme polysaccharide group and spleen polypeptide group (P>0.05), and the effects of radix tetrastigme polysaccharide were dose-dependent.@*CONCLUSIONS@#Radix tetrastigme polysaccharide can inhibit tumor growth, metastasis and immune response in Lewis lung cancer mice, and its mechanism may be related to inhibiting SIRP/CD47 signaling pathway.

Male Infertility Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

In recent years，with the change in lifestyle and social environment and the increase in pressure in both life and work，male fertility has decreased significantly in China，and the incidence of male infertility has increased year by year，which has brought great challenges to andrologists. Traditional Chinese medicine （TCM） has a definite curative effect in the treatment of male infertility and is widely applied in clinical practice. In order to clarify the role of TCM in different types and each stage of male infertility，the China Association of Chinese Medicine （CACM） invited outstanding young andrologists in the clinic of TCM and western medicine to discuss topics such as idiopathic oligospermia and teratospermia，abnormal semen liquefaction，varicocele，immune infertility，improving success ratio of assisted reproductive technology，and ameliorating depression or anxiety. They conducted in-depth discussions on the advantages，characteristics，disadvantages，diseases responding specifically，and advantageous aspects of TCM treatment. The causes of male infertility and related links of treatment were summarized. Due to the unclear etiology and complex pathogenesis of male infertility，western medicine cannot achieve a good curative effect，while TCM，taking the holistic view as the core，specializes in improving functional diseases and can correspond to multiple targets and factors，with comprehensive treatments such as internal treatment and external treatment. This study summarized the advantageous diseases and advantageous stages of TCM treatment alone and integrated TCM and western medicine treatment and put forward suggestions for the treatment of the diseases by TCM and western medicine in order to promote the therapeutic effects and advantages of TCM among andrologists，increase mutual learning and communication between TCM and western physicians，provide patients with excellent and personalized treatment plans in clinical practice，and improve the curative effect of male infertility and fertility of males in China.

Therapeutic effects of the extract of Sancao Formula, a Chinese herbal compound, on imiquimod-induced psoriasis via cysteine-rich protein 61 / 中西医结合学报

OBJECTIVE@#Psoriasis is a common chronic inflammatory skin disease that is prone to recurrence, and the proinflammatory factor, cysteine-rich protein 61 (Cyr61), is important in its pathophysiology. Long-term clinical practice has shown that Sancao Formula (SC), a Chinese herbal compound, is effective in the treatment of psoriasis, but the precise mechanism remains unknown. In this study, we investigate the mechanism by which SC extract alleviates imiquimod (IMQ)-induced psoriasis.@*METHODS@#The expression of Cyr61 in psoriatic lesions and normal healthy skin was detected using immunohistochemical analysis to investigate the biological role of Cyr61 in models of psoriatic inflammation. A psoriatic mouse model was established by topical application of IMQ, and the effect of topical application of SC extract was evaluated using the psoriasis area and severity index (PASI) score, hematoxylin-eosin staining, and histopathological features of the skin. Next, a HaCaT cell inflammation model was established using interferon-γ (IFN-γ), and the effect of SC extract on the mRNA and protein levels of Cyr61 and intercellular cell adhesion molecule-1 (ICAM-1) was confirmed using Western blot and quantitative real-time polymerase chain reaction analyses.@*RESULTS@#Immunohistochemical staining showed that the expression of Cyr61 in psoriatic lesions was higher than that in normal skin samples (78.26% vs 41.18%, P < 0.05), and the number of Cyr61-positive cells in psoriatic lesions was also significantly higher than in normal skin (18.66 ± 2.51 vs 4.33 ± 1.52, P < 0.05). Treatment in mice with IMQ-induced psoriasis showed that SC extract could significantly improve the inflammatory phenotype, PASI score (10.875 ± 0.744 vs 3.875 ± 0.582, P < 0.05), and pathological features compared with those in IMQ model group; SC treatment was also associated with decreased levels of Cyr61 and ICAM-1. In the IFN-γ-induced inflammatory cell model, the mRNA and protein levels of Cyr61 and ICAM-1 were upregulated, while the SC extract downregulated the levels of Cyr61 and ICAM-1.@*CONCLUSION@#The results provide a theoretical basis for the involvement of Cyr61 in the pathogenesis of psoriasis, and suggest that SC should be used to target Cyr61 for the prevention of psoriasis recurrence.

Advantages of Chinese Medicine in Treating Dominant Disease： Benign Prostatic Hyperplasia / 中国实验方剂学杂志

China Association of Chinese Medicine organized specialists in andrology of Chinese and western medicine to explore the population and treatment stage of benign prostatic hyperplasia （BPH） with Chinese medicine as the leading therapy. Chinese medicine has great advantages in the treatment of benign prostatic hyperplasia. However， it is necessary to make clear the stage when Chinese medicine or modern medical treatment can be used as the leading therapy， and the conditions under which Chinese and western medicine can be combined to achieve the best treatment efficacy. The specialists agreed Chinese medicine as the leading therapy for the treatment of BPH in the following populations or conditions： the elderly and weak patients with basic diseases， BPH symptoms， and cannot tolerate anesthesia and surgery， the patients with BPH symptoms and cannot tolerate the adverse reactions or the possible adverse reactions of western medicine； the patients with mild ［international prostatic symptom score （IPSS） ≤ 7］ or moderate lower urinary tract symptoms （IPSS ≥ 8） and the quality of life not significantly affected， the patients with bladder detrusor hypofunction， bladder dysfunction and cannot be treated surgically， or with incomplete bladder emptying after surgical treatment； the BPH patients with prostatitis as the main clinical manifestation， the patients with non-acute complications after operation. BPH is one of the dominant diseases in urology and andrology of Chinese medicine， and the symptoms， complications， and prognosis of BPH patients need to be fully considered during the clinical treatment. When Chinese medicine is taken as the leading therapy， it is essential to regularly review the serum level of prostate-specific antigen to exclude the possibility of prostate cancer， and apply Chinese medicine for full treatment course and cycle. At the same time， Chinese and western medicine can be combined to achieve the most effective， convenient， economical， and satisfactory treatment， which can carry forward the advantages of Chinese medicine in treating this disease.

Vascular endothelial growth factor induces inflammatory injury of pancreatic tissue by activating autophagy in hyperlipidemic acute pancreatitis rats / 生理学报

This study was to investigate the changes of autophagy in pancreatic tissue cells from hyperlipidemic acute pancreatitis (HLAP) rats and the molecular mechanism of autophagy to induce inflammatory injury in pancreatic tissue cells. Male Sprague Dawley (SD) rats were intraperitoneally injected with caerulein to establish acute pancreatitis (AP) model and then given a high fat diet to further prepare HLAP model. The HLAP rats were treated with autophagy inducer rapamycin or inhibitor 3-methyladenine. Pancreatic acinar (AR42J) cells were treated with caerulein to establish HLAP cell model. The HLAP cell model were treated with rapamycin or transfected with vascular endothelial growth factor (VEGF) siRNA. The inflammatory factors in serum and cell culture supernatant were detected by ELISA method. The histopathological changes of pancreatic tissue were observed by HE staining. The changes of ultrastructure and autophagy in pancreatic tissue were observed by electron microscopy. The expression levels of Beclin-1, microtubule- associated protein light chain 3-II (LC3-II), mammalian target of rapamycin complex 1 (mTORC1), and VEGF were measured by immunohistochemistry and Western blot. The results showed that, compared with control group, the autophagy levels and inflammatory injury of pancreatic tissue cells from HLAP model rats were obviously increased, and these changes were aggravated by rapamycin treatment, but alleviated by 3-methyladenine treatment. In HLAP cell model, rapamycin aggravated the autophagy levels and inflammatory injury, whereas VEGF siRNA transfection increased mTORC1 protein expression, thus alleviating the autophagy and inflammatory injury of HLAP cell model. These results suggest that VEGF-induced autophagy plays a key role in HLAP pancreatic tissue cell injury, and interference with VEGF-mTORC1 pathway can reduce the autophagy levels and alleviate the inflammatory injury. The present study provides a new target for prevention and treatment of HLAP.

Modified strict sperm morphology threshold aids in the clinical selection of conventional in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) / 亚洲男科学杂志(英文版)

For infertility treatment, the selection of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is decided by multiplying indicators (including fallopian tube factors, semen count, and semen motility), except for sperm morphology. In this study, we conducted a retrospective analysis, from implantation to birth, over a period of 5 years. A total of 1873 couples with primary or secondary fallopian tube factors and an increased defective sperm morphology rate (DSMR) were divided into different groups to receive IVF or ICSI cycles. By comparing the outcomes, we found that the F1 group (DSMR <96%, IVF group 1) had higher cleavage rate, biochemical pregnancy rate, clinical pregnancy rate, and live birth rate than the F3 group (DSMR >98%, IVF group 3; P < 0.05). In contrast, there was no significant difference in the ICSI subgroups. Furthermore, a comparison of the outcomes between IVF and ICSI showed that the S3 group (DSMR >98%, ICSI group 3) had higher cleavage rate (P < 0.001), biochemical pregnancy rate (P < 0.05), clinical pregnancy rate (P < 0.05) and live birth rate (P < 0.05) than the F3 group. However, the ICSI subgroup had a lower two pronuclei fertilization rate than the IVF subgroup (P < 0.05). Our data suggest that the sperm morphology should also be considered when selecting IVF or ICSI combined with other semen parameters before the first assisted reproductive technologies (ART) cycle, especially for males with severe sperm defects.

Impact of socioeconomic status，population mobility and control measures on COVID-10 development in major cities of China / 浙江大学学报·医学版

:To evaluate the impact of socioeconomic status，population mobility，prevention and control measures on the early-stage coronavirus disease 2019 (COVID-19) development in major cities of China. : The rate of daily new confirmed COVID-19 cases in the 51 cities with the largest number of cumulative confirmed cases as of February 19，2020 (except those in Hubei province) were collected and analyzed using the time series cluster analysis. It was then assessed according to three aspects，that is, socioeconomic status，population mobility，and control measures for the pandemic. : According to the analysis on the 51 cities，4 development patterns of COVID-19 were obtained，including a high-incidence pattern (in Xinyu)，a late high-incidence pattern (in Ganzi)，a moderate incidence pattern (in Wenzhou and other 12 cities)，and a low and stable incidence pattern (in Hangzhou and other 35 cities). Cities with different types and within the same type both had different scores on the three aspects. : There were relatively large difference on the COVID-19 development among different cities in China，possibly affected by socioeconomic status，population mobility and prevention and control measures that were taken. Therefore，a timely public health emergency response and travel restriction measures inside the city can interfere the development of the pandemic. Population flow from high risk area can largely affect the number of cumulative confirmed cases.

OBJECTIVE：To study the mechanism of H uanglian jiedu decoction （HJD）regulating macrophage polarization in order to explore its anti-inflammatory mechanism. METHODS ：The active components and predicted targets of HJD were screened through TCMSP and Swiss Target Prediction database ；the related targets of macrophage polarization were obtained by GeneCards and OMIM database ，and the network diagram of active ingredient-macrophage polarization target of HJD was drawn by using Cytoscape 3.6.0 software；protein interaction network was constructed by String database and core targets were extracted. Gene ontology（GO）enrichment analysis and Kyoto Encyclopedia of genes and genomes （KEGG）pathway enrichment analysis were carried out by using Cytoscape 3.6.0 software and DAVID website. Combined with the results of network pharmacology analysis ， RAW264.7 macrophage cells were divided into blank control group ，model group ，simvastatin group （10 μmol/L）and serum containing HJD group （obtained from the blood after the rats were given HJD at the dose of 10 g/kg）. Except the blank control group and model group were added culture medium ， the other groups were added with 100 μ L of relevant drug solution or serum containing drug. After 2 h of culture ，except for the blank control group ，LPS solution （100 μg/L）was added to the other groups for 24 h to induce inflammation. Western blot assay was used to detect the expression of AMPK. mRNA expression of M 1 type polarization factor （IL-1 β，iNOS）and M 2 type polarization factor （IL-10，Fizz1）were detected by RT-PCR. RESULTS ：A total of 50 active components of HJD （such as acacetin ，wogonin，quercetin，β-sitosterol）were screened ， which could regulate macrophage polarization through 12 GO items （such as anoikis ，astrocyte activation ），and 20 KEGG pathways（such as estrogen signaling pathway ，bladder cancer pathway ，AMPK signaling pathway ）. The results of cell test showed that compared with blank control group ，the expression of AMPK protein ，Fizz1 and IL- 10 mRNA in model group were significantly decreased （P＜0.01），while the expression of IL- 1β and iNOS mRNA were significantly increased（P＜0.01）； compared with model group ，the expression of AMPK protein ，Fizz1 and IL- 10 mRNA in serum containing HJD group and simvastatin group were significantly increased （P＜0.05 or P＜0.01），while the expression of IL- 1β and iNOS mRNA were significantly decreased （P＜0.01）. CONCLUSIONS ：HJD can regulate macrophage polarization through multiple targets and pathways；it can up regulate the expression of M 2-type polarization factors and down-regulate the expression of M 1-type polarization factors through AMPK signaling pathway ，regulate macrophage polarization and play an anti-inflammatory role.

Sirius red staining was used to observe the formation of collagen fibers in the aorta of mice. The serum contents of iNOS and CD 206 were determined by ELISA. mRNA expression levels of IL- 1β，iNOS，TNF-α，YM1 and Fizz1 in the aorta were detected by RT-PCR. RESULTS ：Compared with blank control group ，the serum contents of TC ，TG， LDL-C and iNOS ，mRNA expression levels of IL- 1β，iNOS，TNF-α in the aorta were significantly increased in model group（P＜ 0.05 or P＜0.01），while the serum contents of HDL-C and CD 206 and mRNA expression levels of IL- 10，YM1，Fizz1 in the aorta were significantly decreased （P＜0.01）. There was a thick layer of collagen fibers under the endothelium of aorta. Compared with model group ，above serum indexes of mice were improved significantly in administration groups （P＜0.05 or P＜0.01）；mRNA expression levels of IL- 1 ，iNOS and TNF-α in the aorta in Huanglian jiedu decoction medium-dose and high-dose groups were decreased significantly （P＜0.01），while mRNA expression levels of IL- 10，YM1 and Fizz 1 were increased significantly （P＜0.05 or P＜0.01）. The vascular endothelium was relatively smooth. CONCLUSIONS ：Huanglian jiedu decoction can inhibit the polarization of M 1 macrophages and promote the polarization of M 2 macrophages，reduce the inflammatory reaction ，maintain the stability of atherosclerotic plaque in artery ，so as to play the role of anti-AS.

Obstetric Diseases Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

In recent years， with the change in life style， social environment， and national childbearing policy， the proportion of high-risk pregnant women has increased significantly， triggering the spectrum of obstetric diseases to constantly change， which has brought new challenges to the diagnosis and treatment of obstetrics. Traditional Chinese medicine （TCM） has been proved effective in dealing with a variety of obstetric diseases， and various treatment methods are available， which can serve as alternative means for solving refractory obstetric diseases. However， most obstetric clinicians are currently less aware of the therapeutic effects of TCM， which has significantly hindered its participation in clinical treatment. Therefore， the China Association of Chinese Medicine （CACM） organized the outstanding young obstetricians of TCM and western medicine to discuss 15 obstetric diseases responding specifically to TCM or integrated TCM and western medicine， including hyperemesis gravidarum， threatened abortion， ectopic gestation， cough during pregnancy， pregnancy-induced hypertension syndrome， maternal-fetal ABO incompatibility， postpartum hypogalactia， residual pregnancy tissue in uterine cavity， puerperal infection， pantalgia after childbirth， hematoma/undesirable healing after caesarean section， postpartum urinary retention， ileus after cesarean section， pelvic floor dysfunction， and postnatal depression. The suggestions for their treatment with TCM or integrated TCM and western medicine were also proposed， aiming to provide patients with effective and personalized treatments in clinical practice and improve the diagnosis and treatment effects of obstetric diseases， thus benefiting the public. At the same time， more obstetrical clinicians are expected to understand the therapeutic effects and advantages of TCM and draw on the strengths of both TCM and western， thereby promoting the establishment of an obstetric diagnosis and treatment system with Chinese characteristics.

Expert Consensus on Otorhinolaryngology Head and Neck Diseases Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

Traditional Chinese medicine （TCM） and western medicine have their respective advantages and limitations in the diagnosis and treatment of common otorhinolaryngology head and neck diseases. Although the integrated TCM and western medicine exhibits definite curative effects， there is no consensus on the otorhinolaryngology head and neck diseases responding specifically to TCM or integrated TCM and western medicine， as well as the diagnosis and treatment schemes. The China Association of Chinese Medicine （CACM） thus organized the otorhinolaryngology head and neck specialists of both TCM and western medicine to discuss the etiology， pathogenesis， and clinical diagnosis and treatment methods of common otorhinolaryngology head and neck diseases with the results of multiple clinical trials taken into account. The acute pharyngitis， chronic pharyngolaryngitis， paraesthesia pharyngis， hysterical aphasia， allergic rhinitis， subjective tinnitus， and otogenic vertigo were confirmed to respond specifically to TCM or integrated TCM and western medicine. Then a mutually agreed diagnosis and treatment scheme and recommendation with integrated TCM and western medicine was formulated as a reference for clinical practice， thus benefiting more patients.

Chinese Expert's Perspectives on Andrological Diseases Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

In recent years， the incidence rate of andrological diseases has shown a significant growth trend. Considering the unavailability of a perfect theoretical system for andrology in traditional Chinese medicine （TCM） and the complex pathogenesis despite of the limited types of andrological diseases， it is necessary to improve the clinical efficacy of andrological diseases so as to satisfy the needs of patients. Therefore， the China Association of Chinese Medicine （CACM） organized the andrologists of TCM and western medicine and the outstanding young clinicians to discuss the andrological diseases responding specifically to TCM or integrated TCM and western medicine， such as chronic prostatitis， male infertility， benign prostatic hyperplasia， erectile dysfunction， and premature ejaculation， determine their diagnostic criteria in western medicine， and standardize the specifications for TCM diagnosis and treatment based on syndrome differentiation， thus formulating recognized and integrated diagnosis and treatment protocols. Apart from proposing suggestions on the treatment of such andrological diseases with TCM and western medicine， the experts have also figured out the andrological diseases responding specifically to TCM， the optimal intervention time of TCM and western medicine， and the suitable measures including surgery. The resulting consensus helps to better guide the formulation of accurate， personalized， and optimized treatment plans in clinical practice and improve the diagnosis and treatment effects of andrological diseases by giving full play to the advantages of TCM， which will in turn contribute to further innovation and development of TCM.
