ObjectiveTo investigate the impact of varying concentrations of baicalein on the proliferation and biological responses of MC3T3-E1 cells, as well as the antibacterial efficacy of baicalein against prevalent oral bacteria, and to elucidate the underlying mechanisms. MethodsMC3T3-E1 cells were exposed to different concentrations of baicalein (0, 6, 12, 18, and 24 μmol/L) and cell viability was determined by using the CCK-8 assay. Alkaline phosphatase (ALP) activity of MC3T3-E1 cells following osteogenic induction was assessed. RT-PCR was used to examine the expression of RunX2, BMP2, and Osterix. After 24 hours of treatment, the antibacterial potential of baicalein against Escherichia coli, Staphylococcus Aureus and Streptococcus Sanguis was evaluated by using the K-B paper disk method. ResultsBaicalein exhibited a modest reduction in proliferation of MC3T3-E1 cells but without affecting their sustained proliferation. Baicalein at a concentration of 18 μmol/L enhanced ALP activity of MC3T3-E1 cells, upregulated BMP2 and Osterix expression, downregulated RunX2 expression, significantly inhibited the proliferation of Staphylococcus Aureus and Streptococcus Sanguis (P < 0.05). ConclusionsBaicalein at an optimal concentration (18 μmol/L) demonstrated a promotional effect on the osteogenic differentiation of MC3T3-E1 cells and effectively suppressed the proliferation of common oral bacteria, including Staphylococcus Aureus and Streptococcus Sanguis.

Aim To investigate whether diallyl disul-fide (DADS) augments the sensitivity of DJ-1 (protein/ nucleic acid deglycase) overexpressed human gastric SGC7901 cells to 5-FU (5-fluorouracil). Methods The experimental groups include control group, DADS group, VCR (vincristine) group, VCR + DADS group, DJ-1 group, DJ-1 + DADS group. MTT was used to analyze the effect of DADS on 5 -FU (5 -fluorou- racil) induced proliferation inhibition. Flow cytometry was performed to examine the effect of DADS on cell apoptosis. RT-PCR, Western blot, and immunofluo-rescence were used for determine the effect of DADS on the drug resistance associated gene expression. Results DADS enhanced the proliferation inhibitory effect of 5-FU on DJ-1 overexpressed cells and VCR resistant cells. DADS could induce apoptosis in VCR-resistant cells. DADS downregulated the expression of DJ-1 while inducing apoptosis in DJ-1 overexpressed cells. DJ-1 overexpression upregulated the expression of P-gp (P-glycoprotein), Bcl-2, and XIAP (X-linked inhibitor of apoptosis protein), downregulated the expression of caspase-3. DADS decreased the expression of P-gp, Bcl-2, and XIAP, while increased the expression of caspase-3 in DJ-1 overexpressed cells and VCR-resistant cells. Conclusions DADS can augment the sensitivity of DJ-1 overexpressed cells to 5-FU, which is related to its antagonism against DJ-1 mediated upregula- tion of P-gp, Bcl-2, XIAP, and downregulation of caspase-3.

Objective:To investigate the efficacy of oblique lumbar interbody fusion (OLIF) combined with percutaneous transforaminal endoscopic decompression (PTED) and posterior pedicle fixation through Wiltse approach in the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis.Methods:From June 2017 to February 2022, 103 patients (50 males and 53 females) of lumbar spondylolisthesis accompanied with lumbar spinal stenosis were performed with OLIF combined with PTED and posterior pedicle fixation. The mean age was 64.1±5.2 years (range, 42-87 years). All involved cases were single-segment and included 83 cases of L 4, 5, 17 cases of L 3, 4, and 3 cases of L 2, 3. Among them, 94 cases were performed for the first time, and other 9 were revision surgery treated by posterior lumbar laminectomy previously. The visual analog scale (VAS) was used to evaluate the low back pain and leg pain, and the Oswestry disability index (ODI) was used to evaluate the lumbar function. The VAS and ODI scores were recorded respectively before the operation, at discharge, 1, 3, 6 months after the operation and at the last follow-up. Macnab criteria was used to evaluate the clinical efficacy at the last follow-up. At the same time, imaging measurements were conducted, including the anterior and posterior disc height, segmental lordotic angle, percentage of slip on lateral X-ray film and the vertebral canal area on axial MRI before and after surgery. Results:All of 103 patients were successfully operated in one stage with an average operation time of 177.7±21.5 min (range, 155-220 min), and an average intraoperative blood loss of 55.9±18.3 ml (range, 30-150 ml). The mean follow-up time were 15.1±2.6 months (range, 6-36 months). There were significant differences in both VAS scores of back and leg and ODI scores at each postoperative time point when compared with preoperative ( F=508.25, F=1524.82, F=1148.68, P<0.001). Macnab criteria of the last follow-up was evaluated as follow: excellent in 85 cases, good in 14, fair in 4, and the excellent and good rate was 96.1%. The radiographic results showed the mean immediate postoperative anterior disc height, posterior disc height, segmental lordotic angle, percentage of slip and axial area of the vertebral canal were 15.23±2.97 mm, 9.32±2.31 mm, 14.36°±4.18°, 3.89%±3.11%, 113.37±47.27 mm 2, and thus all of those increased significantly compared to the mean preoperative 11.93±3.17 mm, 7.21±2.03 mm, 6.15°±3.99°, 23.66%±7.79%, 57.63±28.91 mm 2, respectively ( t=7.84, t=7.07, t=14.91, t=27.62, t=9.68, P<0.001). All cases achieved bony fusion during 6-12 months after operation. The incidence of surgery-related complications was 10.7% (11/103). There were 3 cases of end plate fracture and 2 cases of dural injury, which had no complaint after operation. There was 1 case of pedicle screw entering into the spinal canal by mistake, and the symptoms of nerve damage appeared after operation. After 1 year it basically returned to normal. There were 2 cases of thigh numbness and 1 case of psoas major weakness after operation, all of which relieved after 4 weeks. There was 1 case continuous pain of abdominal incision after surgery. There was 1 case of cage subsidence at the last follow-up. Conclusion:OLIF combined with PTED and posterior pedicle fixation through Wiltse approach is a minimally invasive surgical method for the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis. With the combined minimally invasive techniques, the decompression, fusion and fixation of the lumbar spine can be fulfilled perfectly. It has the advantages of minimally invasive, good clical outcome, few complications and rapid rehabilitation.

Aim To investigate the effect of RORα antagonist T0901317 promoting EMT (epithelial-mesenchymal transition) of human gastric cancer MGC803 cells by RORα/β-catenin signal. Methods Cell proliferation was detected by MTT. Cell migration and invasion were detected by cell scratch and Transwell assay respectively. RORα/β-catenin signaling molecules were detected by Western blot and immunofluorescence. RORα binding to β-catenin protein was detected by immunoprecipitation. Results MTT assay showed that the proliferation ability of T0901317 cells increased in a time-dependent manner compared with MGC803 cells (P < 0. 05). Cell scratches and Transwell experiments showed that the migration and invasion ability of T0901317 cells were significantly enhanced compared with MGC803 cells (P < 0. 05). Western blot analysis showed that RORα protein was significantly down-regulated after T0901317 compared with untreated group (P < 0. 05), and total β-catenin protein and nuclear β-catenin in MGC803 cells were up-regulated after T0901317 (P < 0. 05). Compared with the control group, RORα protein binding to β-catenin protein significantly decreased after T0901317 treatment (P < 0. 05). Compared with MGC803 cells treated with T0901317, the long spindle cells increased and the heteromorphism was more obvious. T0901317 significantly up-regulated the expression of Rac1, TGFβ1 and Vimentin in MGC803 cells (P < 0. 05), and inhibited the expression of E-cadherin (P < 0. 05). Conclusion T0901317 can promote the proliferation, migration, invasion and EMT in human gastric cancer MGC803 cells by RORα/β-catenin signal.

OBJECTIVES@#To compare the efficacy of needle retaining after electroacupuncture combined with cognitive training and electroacupuncture combined with cognitive training in the treatment of post-stroke cognitive impairment (PSCI).@*METHODS@#A total of 206 patients with PSCI were randomized into a needle retaining group (103 cases, 9 cases dropped out) and an electroacupuncture group (103 cases, 6 cases dropped out). In addition to the conventional basic medical treatment and the rehabilitation treatment, in the needle retaining group, electroacupuncture at Shenting (GV 24) and Baihui (GV 20) was applied, with continuous wave of 50 Hz in the first 15 min and with disperse-dense wave of 2 Hz/50 Hz in the last 15 min, the needles were continuously retained for 1 h after electroacupuncture, during which cognitive training was adopted; in the electroacupuncture group, cognitive training was performed after the same electric stimulation exerted for 30 min, without additional needles retaining. The treatment was given once a day, 5 times a week for totally 8 weeks in the two groups. Before and after 8-week treatment, the TCM syndrome score was observed; before and after 4,8-week treatment, the scores of mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA) and ability of daily living were observed in the two groups. The clinical efficacy of the two groups was evaluated after 8-week treatment.@*RESULTS@#After 8-week treatment, the TCM syndrome scores were increased compared with those before treatment in both groups (P<0.05); the TCM syndrome score in the needle retaining group was higher than that in the electroacupuncture group (P<0.05).After 4,8-week treatment, the scores of MMSE, MoCA and ability of daily living were increased compared with those before treatment in both groups (P<0.05); MMSE, MoCA scores after 4,8-week treatment and ability of daily living score after 8-week treatment in the needle retaining group were higher than those in the electroacupuncture group (P<0.05). The total effective rate was 90.4% (85/94) in the needle retaining group, which was superior to 82.5% (80/97) in the electroacupuncture group (P<0.05).@*CONCLUSIONS@#Both needle retaining after electroacupuncture combined with cognitive training and electroacupuncture combined with cognitive training can effectively treat PSCI, improve the clinical symptom, cognitive function and ability of daily living in PSCI patients. Needle retaining after electroacupuncture combined with cognitive training has a better therapeutic effect.

Objective:To analyze the relationship between blood electrolytes and the prognosis of patients with severe coronavirus disease 2019 (COVID-19) and to provide assistance for clinical decision-making.Methods:The clinical data of patients with severe COVID-19 admitted to intensive care unit (ICU) of the Wuhan Third Hospital by the Shanghai aid-Hubei medical team from January 21 to March 4, 2020 were collected. Excluding ineligible patients, 110 patients were finally enrolled. The patients' gender, age, temperature, heart rate, systolic and diastolic blood pressure, clinical symptoms at admission, time of symptom onset, duration of fever, and relevant indicators at admission to ICU (including blood potassium, chloride, sodium, calcium, phosphorus, and magnesium, etc.) and prognosis were analyzed. The patients were grouped by blood potassium or calcium levels or blood potassium/calcium ratio. The Kaplan-Meier survival curves were used to analyze the survival of patients in each group. The relationship between the potassium/calcium ratio and the prognosis was analyzed using restricted cubic spline plots. The relationship between each index in the different models and the prognosis was analyzed using Cox regression models.Results:Among 110 severe COVID-19 patients, 78 cases survived, and 32 cases died. Compared with the surviving group, patients in the death group had higher blood potassium levels [mmol/L: 4.25 (3.80, 4.65) vs. 3.90 (3.60, 4.20), P < 0.05] and lower blood calcium levels (mmol/L: 2.00±0.14 vs. 2.19±0.18, P < 0.05). The Kaplan-Meier survival curves showed that patients in the potassium > 4.2 mmol/L group had a worse prognosis than the potassium < 3.8 mmol/L group and the potassium 3.8-4.2 mmol/L group ( P = 0.011), patients in the calcium > 2.23 mmol/L group had a better prognosis than the calcium < 2.03 mmol/L group and the calcium 2.03-2.23 mmol/L group, and the lower calcium group had a worse prognosis ( P = 0.000 15). Cox regression analysis showed that the hazard ratio ( HR) of blood potassium and calcium were 2.08 and 0.01, respectively, in model 1 (single blood potassium or calcium) and in model 2 (model 1 plus age and gender), the HR of blood potassium and calcium were 1.98 and 0.01 respectively, which were significantly associated with patient prognosis (all P < 0.05). Patients in the group with the potassium/calcium ratio > 1.9 had higher blood potassium levels and a higher proportion of mechanical ventilation, lower calcium levels and lower proportion of survival, and longer time of ICU admission compared with the groups with the potassium/calcium ratio < 1.7 and 1.7-1.9. The Kaplan-Meier survival curves showed that the survival rate of the potassium/calcium ratio > 1.9 group was the lowest ( P < 0.000 1), and there was no statistically significant difference in survival between the potassium/calcium ratio < 1.7 group and the potassium/calcium ratio 1.7-1.9 group. A restricted cubic spline plot corrected for age and gender showed that patients in the potassium/calcium ratio > 1.8 group had HR values > 1. Cox regression analysis corrected for other indicators showed that the potassium/calcium ratio was still associated with patient prognosis ( HR = 4.85, P = 0.033). Conclusions:Blood potassium, calcium, and the potassium/calcium ratio at ICU admission are related to the prognosis of patients with severe COVID-19, and the potassium/calcium ratio is an independent risk factor for the death of patients. The higher the potassium/calcium ratio, the worse the prognosis of patients.

OBJECTIVE@#To investigate the characteristics of pathogen infection and to establish a prediction model of infections in oral squamous cell carcinoma patients undergoing surgery with free flap reconstruction.@*METHODS@#The retrospective cohort study consisted of 1 596 patients undergoing tumor resection and free flap reconstruction for oral squamous cell carcinoma from January 2018 to December 2020. According to the postoperative infection, the patients were divided into the infected group (n=154) and non-infected group (n=1 442). The characteristics of pathogens were analyzed in the infected patients. The primary outcome variable was postoperative infection, and Logistic regression was used to determine risk factors of the infection. The prediction model was established and the discriminatory accuracy of the model was evaluated using receiver operating characteristic (ROC) curve.@*RESULTS@#Totally 154 cases were infected in the 1 596 cases undergoing surgery with free flap reconstruction, and the infection rate was 9.65%. The most frequent sites of infection were the surgical wound and respiratory tract. A total of 268 pathogens were isolated and cultured, including 240 strains of Gram-negative bacteria, accounting for 89.55%, mainly Pseudomonas aeruginosa and Klebsiella pneumoniae; 23 strains of Gram-positive bacteria, accounting for 8.58%, mainly Enterococcus faecalis and Staphylococcus aureus; and 5 strains of fungi, accounting for 1.87%. The isolated Pseudomonas aeruginosa had high resistant rate to imipenem and meropenem, and was sensitive to antibiotics, such as ciprofloxacin. The isolated Staphylococcus aureus had high resistant rate to erythromycin and clindamycin, and was sensitive to vancomycin. According to the multivariate Logistic analysis, four independent variables were significantly associated with an increased risk of postoperative infection (P < 0.05): clinical N category≥1, the American Society of Anesthesiologists (ASA) grade ≥2, tracheotomy and length of hospital stay >13 d. The prediction model was established based on these factors and the expression of the risk prediction model was as follows: predicted probability value P=1/(1+e-a), a=-0.803+0.674×(clinical N category ≥1)+0.518×(the ASA grade ≥2)+0.918×(tracheotomy)+1.581×(length of hospital stay >13 d), Hosmer-Lemeshow χ2=10.647, P=0.223, the degree of fitting of the model was good. The area under the ROC curve was 0.818 and 95%CI of the model for predicting infection was 0.789-0.846.@*CONCLUSION@#Oral squamous cell carcinoma patients undergoing surgery with free flap reconstruction are prone to have a high incidence of postoperative infection and Gram-negative bacteria are the main pathogens causing an infection. The established prediction model is of good predictive effect. Rational antimicrobial use coupled with awareness of infection control measures is paramount to reduce the incidence of postoperative infection in the oral squamous cell carcinoma patients undergoing surgery with free flap reconstruction.

Due to the complicated anatomical structures in the furcation area of multirooted mandibular first molars, dental hygiene is greatly compromised once the furcation is involved in the periodontitis, leading to the unfavorable prognosis of teeth with furcation involvement. A patient came to a dental office with the chief complaint of "mobile mandibular posterior tooth" 27 years ago. The periapical film showed alveolar bone resorption at the root furcation of the right mandibular first molar. Flap surgery and fine supportive therapy were conducted. The patient was diagnosed with "furcation involvement Class Ⅲ" during a revisit three years ago. Satisfactory and healthy periodontal statuses were observed 2, 9, 24, and 33 months after the periodontal flap surgery plus tunneling procedures. A follow-up of 27 years in the present case demonstrated that a favorable prognosis of furcation involvement can be achieved after adequate periodontal treatment.

Objective:To review and summarize the current research status of traditional Chinese medicine(TCM) for the treatment of chronic atrophic gastritis(CAG),provide references and hints for relevant studies,and contribute to the further understanding of TCM and the application of TCM in the treatment of CAG with scientific evidence. Method:The PubMed and Web of Science databases were searched for relevant literature on the treatment of CAG with TCM from their establishment to August 31,2020. Eligible randomized controlled trials (RCTs) and animal studies were included according to the inclusion and exclusion criteria,and then the information of the included studies was extracted,summarized,and organized for further analysis. Result:A total of 4 RCTs and 21 animal studies (including 13 papers on compound studies,3 papers on single herb studies,and 5 papers on monomer studies) about TCM treatment for CAG were included in this study. RCTs showed that TCM could work well in improving the pathological state of gastric mucosa and clinical symptoms in patients. However,there were problems of low study quality,and non-uniform diagnostic criteria for gastric mucosal pathology and clinical efficiency evaluation. Animal experiments mainly focused on the study of drug mechanism exploration,and their results showed that TCM treatment of CAG was characterized by multi-target action. However,the animal experiments also had some problems such as inconsistence of CAG animal model establishment,positive drug selection,drug intervention methods as well as intervention cycles among different experiments. Conclusion:The efficacy of TCM in the treatment of CAG has gradually gained global recognition,but there is still a need for further standardization and unification of research methods. In the future,high-quality clinical trials and standardized animal experiments are still needed to conduct in-depth studies on the time for intervention,intervention methods,active ingredients and mechanisms of TCM,so as to make contributions to the full understanding and application of TCM in the treatment of CAG.

Objective:To explore the effect of phacoemulsification through corneoscleral incision on cataract patients with type 2 diabetes mellitus.Methods:A prospective case-control study was conducted to collect cataract patients with type 2 diabetes who were admitted to the First Hospital of Hebei Medical University from January 2018 to June 2019. All patients were treated with phacoemulsification. They were randomly divided into three groups: 40 cases (68 eyes) of corneoscleral incision, 40 cases (66 eyes) of upper transparent corneal incision and 40 cases (70 eyes) of temporal transparent corneal incision. The dry eye symptom scale score, corneal fluorescein staining (FL) score, tear rupture time (BUT) and Schirmer I test (SIt) were compared in three groups; The levels of interleukin-6 (IL-6) and interleukin-8 (IL-8) in aqueous humor were compared among the three groups before and 7 days after operation.Results:⑴ The levels of IL-6 and IL-8 in aqueous humor of the three groups were significantly lower than those before operation, especially in group A ( P<0.05), but there was no significant difference in the levels of IL-6 and IL-8 in aqueous humor of group B and C ( P>0.05); ⑵ The scores of dry eye symptoms in group B were significantly higher than those in group A at 1 and 7 days after operation ( P<0.05); The scores of dry eye symptoms in group C were significantly higher than those in group A and B at 1, 7 and 30 days after operation ( P<0.05); The dry eye symptom score in group A and B decreased to the preoperative level 30 days after operation ( P>0.05), and that in group C decreased to the preoperative level 90 days after operation ( P>0.05); ⑶ The postoperative 1, 7 and 30 d BUT in group A and C were significantly higher than those in group B ( P<0.05), and the level of SIt was significantly lower than that in group B ( P<0.05); At 1 and 7 days after operation, SIt in group A was significantly lower than that in group C ( P<0.05); the FLS score in group A and C was significantly lower than that in group B at 1 and 7 days after operation ( P<0.05). Conclusions:The incision of corneoscleral margin has little effect on tear film stability and ocular surface function of cataract patients with type 2 diabetes mellitus treated by phacoemulsification, which is worthy of clinical recommendation.
Résumé
Melasma, as a kind of melanosis, often occurs over the face of young and middle-aged women, which seriously affects the physical and mental health of patients. At present, it is believed that the occurrence of melasma is related to various factors such as ultraviolet radiation and changes in sex hormone levels in the body. However, the exact pathogenesis of melasma is still unclear and its clinical efficacy is not ideal. Therefore, it is of great clinical significance and social value to carry out basic researches on melasma diseases. Among them, the animal model of melasma acts as an important tool for studying melasma, and it is particularly important to clarify the pathophysiological mechanism of the occurrence and development of melasma. The common modeling methods include ultraviolet modeling, progesterone modeling and ultraviolet combined with progesterone modeling. However, there are still some problems in the practical application of animal models of melasma due to many influencing factors in the preparation of such animal models, and there is still a lack of a more complete and recognized model preparation scheme to this day, which reduces the success rate of model preparation and limits its application and popularization to some extent. In view of the key problems in the establishment and application of animal models of melasma, we comprehensively summarized the research status of the models from such aspects as experimental animals, modeling methods and model evaluation, and discussed the effects of different modeling methods and animal species, animal age and other factors on animal model of melasma by referring to and sorting out the recent literatures at home and abroad in recent years. This is to provide references for the preparation of more scientific, reasonable, economic and convenient animal models of melasma, lay a foundation for in-depth researches on the pathogenesis, prevention and treatment of melasma, and also provide reference for other animal model research.

Descriptive epidemiology (population distribution, time distribution, regional distribution) and clinical characteristics analysis of brucellosis were conducted in Huai'an City from 2013 to 2018. Results Totally 704 cases of brucellosis had been reported in Jiangsu Province, with an average annual incidence of 0.1467/100000, among which 32 cases (4.55%) had been reported in Huai'an, with an average annual incidence of 0.1100/100000 from 2013 to 2018. The annual outcomes (incidence rates) were 2 (0.0416/100000), 4 (0.0834/100000), 6 (0.1247/100000), 6 (0.1232/100000), 8 (0.1636/100000) and 6 (0.1221/100000), respectively. Most of the cases were males (20 cases, 62.5%), and aged mainly focused from 40 - < 60 years old (20 cases, 62.5%). The occupation was mainly farmers (21 cases, 65.6%). The contact with animals was mainly sheep, and the contact mode was feeding and slaughtering. The cases mainly occurred from March to September (26 cases), and all districts had cases except Hongze. The main clinical manifestations were fever, fatigue, hyperhidrosis and arthromyalgia, with 30 cases (93.8%), 28 cases (87.5%), 25 cases (78.1%) and 22 cases (68.8%), respectively. Some cases showed enlargement of liver, spleen, lymph nodes and testis. Conclusions The incidence of brucellosis in Huai'an City is on the rise, and the characteristics of population distribution, time distribution and regional distribution are obvious. The clinical features are mainly fever, fatigue, and hyperhidrosis. We should strengthen the monitoring of brucellosis, carry out health education for high -risk groups, and reduce the occurrence of brucellosis.
Résumé
Objective To discuss the expression of caspase-7 (CASP7) and its prognostic role in colon cancer. Methods CASP7 expression data was retrieved from Ualcan database, and the survival data of CASP7 down-regulated colon cancer patients was retrieved from Ualcan database and Oncolnc database. Results In colon cancer, the expression of CASP7 was down-regulated and indicated a relatively worse prognosis. The expression of CASP7 was correlated with KRAS and TP53I3. Conclusions CASP7 is down-regulated in colon cancer and indicates a worse prognosis.
Résumé
Objective To explore the clinical value of neutrophil/lymphocyte ratio (NLR) in staging of stage Ⅱ/Ⅲ middle and low rectal cancer. Methods The clinical and pathological data of 111 patients with middle and low rectal cancer who underwent surgical treatment were retrospectively analyzed. The NLR values along with various clinical factors and pathological parameters were also statistically analyzed, and then the relationship between preoperative NLR and various clinical factors was determined. All patients were divided into high and low groups based on NLR, with the cut-off value of 1.99. Then, the clinical, pathological parameters and disease-free survival of the two groups were analyzed. Results The maximum diameter of the tumor and the NLR value were positively correlated (P < 0.05). The patients with high and low NLR had significant differences in age, stage Ⅱ and Ⅲ, N stage, pathological type, maximum diameter of the tumor, and disease-free survival (P < 0.05). Conclusion Preoperative NLR values may be used as predictive values for the pathological parameters of stage Ⅱ and Ⅲ middle and low rectal cancer, and NLR may be an indicator of its prognostic assessment.

Résumé
Objective:Based on the experience of famous doctors, the pattern of syndromes of benign prostatic hyperplasia (BPH) and the distribution of syndrome elements are defined to provide a basis for guiding clinical practice and scientific research. Method:The name list of famous doctors was defined. Relevant literatures on famous doctors' diagnosis and treatment of BPH between January 1, 1997 and December 31, 2018, were systematically retrieved in CNKI, CBM, CQVIP, Wanfang database. According to the inclusion criteria and exclusion criteria, relevant literatures were read, and eligible literatures were included. A literature analysis database was established for analysis and integration of relevant content of traditional Chinese medicine(TCM) syndromes and syndrome elements. SPSS 20.0 software was used for statistics and analysis of BPH TCM syndrome types and distribution characteristics of syndrome elements. Result:This study included a total of 141 eligible documents, involving 92 famous doctors. Based on the doctors' overall discussion of BPH and medical case examples, common types of BPH syndrome included kidney deficiency and blood stasis syndrome, bladder dampness syndrome, kidney Yin deficiency syndrome, kidney Yang deficiency Syndrome, liver Qi stagnation syndrome, main symptom factors of disease location included kidney, bladder, spleen, lung, liver, and main symptom factors of disease nature included blood stasis, Qi deficiency, heat, yang deficiency, and dampness. The characteristics of the symptoms in the medical case were collected and summarized, including frequent urinary symptoms, frequent urination, urinary drip, urgency, nocturia, difficulty in urinating, the tongue is mainly light red, red, dark red, and sputum, the tongue coating is mainly yellow, thin white, thin yellow and white greasy, and the pulse is mainly composed of deep, fine, string and slipping.
