ObjectiveTo investigate the distribution of traditional Chinese medicine (TCM) syndrome types and syndrome elements of nonalcoholic fatty liver disease (NAFLD). MethodsRelated databases (CNKI, Wanfang Dota, and VIP)were searched for articles on the syndrome differentiation of NAFLD published up to July 2020. Two investigators independently performed literature screening and collection and summarization of syndrome types based on the inclusion and exclusion criteria, and an Excel 2010 database was established after the standardization of syndrome names, re-decomposition of syndrome types, and extraction of syndrome elements. The data were imported into SPSS 25.0 statistical software for the analysis of frequency distribution. ResultsA total of 45 qualified articles were collected, with a total of 8703 cases reported. A total of 14 syndrome types were obtained after standardization, and 10 syndrome elements reflecting the nature of disease and 4 syndrome elements of disease location were obtained after the syndrome types were disassembled. Stagnation of liver Qi and spleen deficiency syndrome (26.47%) and damp-heat accumulation syndrome (22.16%) were the most common syndrome types, followed by stagnation of phlegm dampness, intermingled phlegm and blood stasis, and stagnation of liver Qi and Qi stagnation. Dampness (23.75%), Qi stagnation (19.82%), Qi deficiency (17.12%), phlegm (15.43%), and heat (12.13%) were the most common syndrome elements reflecting the nature of disease, followed by stasis, Yin deficiency, and Yang deficiency, while fire and cold were relatively uncommon. Qi stagnation and Qi deficiency (26.63%), dampness and heat (22.30%), phlegm and dampness (16.17%), and phlegm and stasis (12.19%) were the most common combinations of syndrome elements. The liver and the spleen were the most common syndrome elements of disease location, accounting for 90.95% of the constituent ratio, and the combination of the liver and the spleen with the same disease accounted for 54.01%. The combination of one, two, three, or four syndrome elements was observed, and the combination of two syndrome elements accounted for 76.03%. ConclusionStagnation of liver Qi and spleen deficiency are the basic pathogeneses of NAFLD, and liver, spleen, dampness, Qi stagnation, Qi deficiency, phlegm, and heat are common syndrome elements. Dampness, phlegm, and heat are important factors for the development and progression of this disease.

Objective To study the efficacy and safety of bronchial artery embolization(BAE)with tris-acryl gelatin microspheres(TAGM)combined with platinum spring coil with fiber(microcoils)in the treatment of acute severe hemoptysis caused by bronchiectasis.Methods A retrospective analysis of 48 patients with bronchiectasis was performed.After the lesion vessels were confirmed by angiography,the distal capillary bed was embolized with TAGM(300-500 μm),the middle blood flow was embolized with microcoils according to the diameter of the small artery,and then the proximal vessels were embolized with TAGM(500-700 μm)again.In patients with pulmonary artery/vein fistula,appropriate TAGM(500-700 μm)was selected according to the size of the fistula and the blood flow velocity,followed by dense embolization with multiple microcoils.The complete occlusion of the lesion vessel was confirmed again by arteriography after embolization.Results The overall success rate of operation was 95.83％.There were 36 patients with immediately stopped bleeding,6 cases with effective treatment,4 cases with improved treatment,1 case with invalid treatment due to the leakage of the responsible blood vessel,which was improved after the second embolization.There was 1 case died in surgery due to sudden massive hemoptysis,choking and suffocation.During the 3-51 months follow-up,1 patient died due to sudden massive hemoptysis;4 patients had recurrent hemoptysis due to poor control of infection and collateral circulation,which were controlled after reemboliza-tion,and 1 patient with bronchiectasis and pulmonary tuberculosis had repeated hemoptysis caused by multiple pulmonary lesions and severe pulmonary infection,performing on four times embolization.There was no patient with recurrent hemoptysis occurring recanalization of primary embolized vessel.During the follow-up,the overall survival rate was 97.87％,and the hemoptysis control rate was 87.23％.Conclusion TAGM combined with microcoils is safe and effective in the treatment of acute massive hemoptysis,which has good short-term effect and long-term prognosis.

Prostate cancer (PCa) is one of the most common tumors in men.In recent years, various researches on this disease and clinical applications have benefited patients.Exosome is a subclass of extracellular vesicles (EVs).Many studies have explored the mechanisms of exosome in mediating epithelial mesenchymal transformation, angiogenesis, tumor microenvironment establishment, immune escape and drug resistance acquisition in PCa, which provides a new perspective for finding new diagnostic markers.This article reviews the role of exosome in the pathogenesis of PCa and its diagnostic application.

There are few reports on the use of Allium stents in the treatment of membranous urethral stricture in China. Its safety and effectiveness need to be observed. This study retrospectively analyzed the data of 5 patients admitted to our hospital for the treatment of membranous urethral stricture using Allium-covered metal urethral stents in the past 5 years. The preoperative International Prostatic Symptom Score (IPSS) score was 8.80±1.30, quality of life(QOL)score was 4.20 ±0.84, and the International Index of Erectile Function-5(IIEF-5) score was 20.20 ± 1.92, respectively. Six months after the operation, the IPSS score was 3.60±1.52, the QOL score was 1, and the IIEF-5 score was 19.80±1.48. This operation is easy with little invasion. It can alleviate the dysuria of patients with membranous urethral stricture and has little impact on the sexual function of patients. It is generally safe and controllable, but the appropriate time for implantation still needs to be explored.

Objective To explore the erectile function preservational mechanism of Non-transecting urethroplasty(NTU) for posterior urethral stricture.Methods From May 2012 to September 2016,62 patients with posterior urethral stricture,who were treated with NTU,were enrolled in this study.The mean age was 37.5 years old,ranging 18-48 years old.The causes were pelvic fracture urethral injury in 53 cases and iatrogenic injury in 9 cases.Preoperative urethrography and urethroscopy revealed the strictures located in posterior urethra,which was at the distal of verumontanum.The mean length of stricture was 2.1 cm,ranging 0.5-2.5 cm.The average period between trauma and surgery was 6.4 months,ranging 3 months-2 years.All patients had no previous history of urethroplasty.Their sexual hormones were in normal level.Among those patients,the IIEF-5 scores were more than 12 and number of events during NPT test were more than twice.Finally,43 cases were underwent NTU and 19 cases accepted inferior pubectomy (IP)+ NTU.All patients had a general anesthesia.The bulbar urethra was mobilized dorsally from the tunica albuginea of the corpora cavernosa and then extended proximally up toward the perineal membrane.Scar tissue surrounding the urethra was excised and inferior pubectomy (IP) was performed as a supplemental technique to keep the suturing position without tension.The ventral hemi-circumference was then sutured with interrupted 4-0 polyglycolic sutures with tension-free anastomosis.The 18-Fr indwelling catheter was inserted.Result Average follow-up was 20.2 months,ranged from 12 to 36 months.In NTU group,NPT test revealed no significant difference in number of events (2.7 ± 0.7 vs.3.0 ± 1.0,P ＞ 0.05),duration of best episode [(16.4 ± 3.5) min vs.(16.4 ± 3.8) min,P ＞ 0.05)] or tip rigidity [(31.2 ± 4.7) ％ vs.(30.8 ± 3.5) ％,P ＞ 0.05)] between pre-and post-operation,respectively.The IIEF-5 score (19.7 ± 1.9 vs.20.4±2.1,P＜0.05)and Qmax[(8.7 ±4.0)ml/s vs.(25.5 ±4.7)ml/s,P＜0.05)] increased significant pre-and post-operation,respectively.In IP + NTU group,Qmax [(8.4 ± 4.4) ml/s vs.(23.1 ± 3.5)ml/s,P ＜ 0.05)] increased significant pre and post operation.The NPT test revealed slight decrease in number of events(2.3 ± 0.6 vs.1.6 ± 1.0,P ＜ 0.05),duration of best episode [(15.6 ± 2.4) min vs.(14.5±2.4)min,P＜0.05)] or tip rigidity [(29.8±3.0)％ vs.(25.6 ±7.1)％,P＜0.05)] between pre-and post-operation,respectively.However,the IIEF-5 scores (17.3 ± 1.6 vs.16.5 ± 2.1,P ＜ 0.05) didn't show significant difference pre-and post-operation.Stricture recurrence occurred in 3 patients,the success rate was 95.2％ (59/62) during 12 months following.Conclusion NTU is not only a safe and promising procedure for posterior urethral stricture less than 2.5cm,but also a new minimally invasive approach to preserve erectile function.

Objective:To verify the clinical efficacy and safety of Qufeng Tongxuan method in treating low- and moderate-volume intracerebral hemorrhage at acute stage.Methods:A prospective, multicenter, randomized, double-blind, placebo-controlled study was performed; patients with low- and moderate-volume intracerebral hemorrhage at the basal ganglia and/or thalamus accepted treatment in 16 hospitals from September 2019 to April 2022 were enrolled. These patients were divided into experimental and control groups with a block randomized method by SAS software. Patients in control group were given conventional western medicine treatment; those in experimental group accepted Qufeng Tongxuan method (sequential therapy of Shexiang Huayu Xingnao granules and Zhilong Huoxue Tongyu granules) besides conventional western medicine treatment. NIHSS was used to assess neurological function before treatment and on 7 th, 14 th, 30 th, and 90 th d of treatment. Prognoses of these patients were assessed by modified Rankin scale (mRS) before treatment and on 180 th d of treatment. Brain CT was performed before treatment and on 7 th and 14 th d of treatment to calculate the hematoma volume. Before treatment and on 14 th d of treatment, changes of coagulation function, liver and kidney functions of the 2 groups were compared. Adverse reactions during treatment in the 2 groups were recorded. Results:No significant differences in NIHSS scores were noted between the 2 groups before treatment, on 7 th, 14 th, and 30 th d of treatment ( P>0.05); NIHSS scores in experimental group on 90 th d of treatment were signficantly lower than those in control group ( P<0.05); NIHSS scores in experimental group decreased gradually before treatment and on 7 th, 14 th, 30 th and 90 th d of treatment, with statistical significances ( P<0.05). No significant differences in mRS scores were noted between the 2 groups before treatment ( P>0.05); mRS scores in experimental group on 180 th d of treatment were signfciantly lower than those in control group ( P<0.05). No significant difference in hematoma volume was noted between the 2 groups before treatment and on 7 th and 14 th d of treatment ( P>0.05); both groups had gradually decreased hematoma volumes before treatment and on 7 th and 14 th d of treatment, respectively, with significant differences ( P<0.05); the volume difference of hematoma between 14 th d of treatment and before treatment in experimental group (6.42[4.10, 11.73]) was significantly higher than that in control group (4.00[1.25, 10.58], P<0.05). No significant differences in liver and kidney function indexes or coagulation function indexes were noted between the 2 groups before treatment and on 14 th d of treatment ( P>0.05). Adverse reaction incidence was 9.52% ( n=12) in experimental group and 10.34% ( n=12) in control group, without statistical difference ( P>0.05). Conclusion:Under premise of conventional western medicine treatment, Qufeng Tongxuan method can promote hematoma absorption and improve neurological deficit symptoms in low- and moderate-volume intracerebral hemorrhage at acute stage, without obvious adverse reactions.
