Shengyutang is a famous classical formula of tonic， which is made from Siwutang with Ginseng Radix et Rhizoma and Astragali Radix. It is included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. Based on the Principles of Key Information Research of Ancient Famous Classical Formulas， this paper used bibliometrics to sort out and research the key information of Shengyutang in the aspects of history， composition， origin and processing， dosage， decocting method， efficacy and indications. After research， it has been found that this formula was first recorded in Lanshi Micang written by LI Dongyuan during the Jin dynasty， composed of Rehmanniae Radix， Rehmanniae Radix Praeparata， Chuanxiong Rhizoma， Ginseng Radix et Rhizoma， Astragali Radix and Angelicae Sinensis taproot. The name of the formula passed down through generations was relatively unified， with clear origins and veins. In later generations， this formula was the mainstream， and adjustments were made to the dosage and composition according to the indication. In the formula， Astragalus membranaceus var. mongholicus was selected as the origin of Astragali Radix， and the origins of other medicinal materials were consistent with the 2020 edition of Chinese Pharmacopoeia. Except for Rehmanniae Radix Praeparata， the other medicinal materials were made from raw products， and the dosage form was boiled powder. According to the measurement standard in the Jin dynasty， the recommended usage and dosage were 1.24 g of Rehmanniae Radix， Rehmanniae Radix Praeparata， Chuanxiong Rhizoma， Ginseng Radix et Rhizoma each， 2.07 g of Astragali Radix and Angelicae Sinensis taproot each， crushed into coarse particles that pass through the 4 mesh sieve but can't pass through the 10 mesh sieve， added 1 200 mL of water and boiled to 300 mL， and removed the residue. Shengyutang has the functions of tonifying Qi and blood， and blood intake， treating various sores， and restlessness and insomnia caused by excessive blood flow. In ancient times， this formula was widely used in the treatment of surgical sores， gynecological diseases， deficiency syndrome， etc. In modern clinical practice， it is mostly used to treat gynecological， neurological， musculoskeletal， hematological diseases caused by Qi and blood deficiency. In this paper， the key information of Shengyutang was researched by reviewing relevant ancient literature， in order to provide reference for the modern application and development of this formula.

[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

BACKGROUND:Buqi Huoxue Compounds have significant clinical efficacy in treating ischemic stroke with Qi deficiency and phlegm stasis;however,the exact mechanism of action is not clear. OBJECTIVE:To observe the effect of Buqi Huoxue Compounds on the expression of vascular endothelial growth factor,basic fibroblast growth factor,brain-derived neurotrophic factor and autophagy related protein Beclin1 and p62 in a rat model of cerebral ischemia/reperfusion. METHODS:Forty male Sprague-Dawley rats were randomly divided into sham operation group,model group,Buqi Huoxue Compounds group and autophagy inhibitor group,with 10 rats in each group.In the latter three groups,a rat model of cerebral ischemia/reperfusion injury was established.The Buqi Huoxue Compounds group was intragastrically given Buqi Huoxue Compounds(6.49 g/kg,administered three times a day)2 hours after reperfusion;the autophagy inhibitor group was intragastrically given Buqi Huoxue Compounds(6.49 g/kg,administered three times a day)2 hours after reperfusion and intraperitoneally given 3-methyladenine 2 hours before gavage and at days 1-3 of gavage.The sham operation group and model group were given equal amounts of saline by gavage for 7 consecutive days.Neurological function,cerebral infarct volume,brain tissue morphology and expression of vascular endothelial growth factor,basic fibroblast growth factor,brain-derived neurotrophic factor and autophagy-related proteins Beclin1 and p62 in the ischemic cortical region of rats were detected at 24 hours after the final administration. RESULTS AND CONCLUSION:Zea-Longa scoring results showed that the neurological function of rats was severely damaged after modeling and neurological deficit of rats in the Buqi Huoxue Compounds group was less than that in the model group and the autophagy inhibitor group(P＜0.05).TTC staining showed that cerebral infarct foci were observed in the model group,Buqi Huoxue Compounds group,and autophagy inhibitor group,and the cerebral infarct volume in the Buqi Huoxue Compounds group was lower than that in the model group and the autophagy inhibitor group(P＜0.05).The results of hematoxylin-eosin staining in ischemic brain tissues showed that there were large gaps between nerve cells in the model group and cell arrangement was not neat,and cytoplasmic agglutination and pyknosis were observed.Immunohistochemical staining results showed that vascular endothelial growth factor was mostly expressed in neuronal cells,glial cells and capillary endothelium;basic fibroblast growth factor and brain-derived neurotrophic factor were mostly expressed in neuronal cells and glial cells;and there was no significant difference in the expression of vascular endothelial growth factor,basic fibroblast growth factor,and brain-derived neurotrophic factor among the four groups(P＞0.05).The results of western blot assay showed that compared with the sham operation group,Beclin1 protein expression was decreased(P＜0.05)and p62 protein expression was elevated(P＜0.05)in the model group;compared with the model group,Beclin1 protein expression was increased(P＜0.05)and p62 protein expression was reduced(P＜0.05)in the Buqi Huoxue Compounds group;compared with the Buqi Huoxue Compounds group,Beclin1 protein expression was decreased(P＜0.05)and p62 protein expression was elevated(P＜0.05)in the autophagy inhibitor group.To conclude,Buqi Huoxue Compounds attenuate cerebral ischemia-reperfusion injury in rats by promoting autophagy.

As one of the major diseases threatening human health,the early accurate diagnosis and localization of tumors are crucial for formulating effective treatment plans.In recent years,molecular probes(MPs)have made significant progress in the field of biological imaging.With advantages such as high sensitivity,high specificity,and non-invasiveness,they have become a research hotspot in the field of tumor diagnosis and treatment.This paper systematically reviews the applications of MPs in tumor diagnosis and treatment,covering their classifications(such as fluorescent,photoacoustic,chemiluminescent,bioluminescent,and multimodal probes),design strategies(including active/pas-sive targeting mechanisms and the synergistic construction of identification units,imaging units,signal conversion units and treatment units),as well as detection principles.It also focuses on elabo-rating the research progress of MPs based on enzymes,receptors,reactive substances,and tumor microenvironment.Meanwhile,this paper emphasizes the advantages of multifunctional integration and multimodal imaging,and analyzes the challenges faced by MPs in clinical translation(such as biocompatibility and optimization of supporting equipment).It aims to provide ideas for the develop-ment of high-performance MPs and promote the advancement of precise and personalized tumor di-agnosis and treatment.

BACKGROUND:Buqi Huoxue Compounds have shown significant clinical effects on the treatment of ischemic stroke due to qi deficiency and phlegm stasis,but its specific mechanism of action needs to be further clarified.OBJECTIVE:To observe the effects of Buqi Huoxue Compounds on the neurological function,p-Akt and serum exosome expression in a rat model of cerebral ischemia-reperfusion injury.METHODS:Forty adult male SPF Sprague-Dawley rats,6 weeks old,were randomly divided into sham operation group,model group,Buqi Huoxue Compounds group,Buqi Huoxue Compounds+GW4869 group,with 10 rats in each group.In the latter three groups,a rat model of cerebral ischemia-reperfusion injury was established using thread technique.The sham operation group was given incision and separation without inserting a suture.The Buqi Huoxue Compounds group was intragastrically given Buqi Huoxue Compounds(6.49 g/kg,administered three times a day)2 hours after reperfusion;the GW4869+Buqi Huoxue Compounds group was intragastrically given Buqi Huoxue Compounds(6.49 g/kg,administered three times a day)2 hours after reperfusion and intraperitoneally given GW4869[2.5 mg/(kg·d)]2 hours before gavage with 3 days after modeling.Both the sham operation group and model group received equal amounts of saline via gavage,three times a day,for 7 consecutive days.Neurological function,cerebral infarct volume,brain tissue morphology,characterization of serum exosome,p-Akt in the cortical area and CD63 and TSG101 in serum exosome were detected after 7 days of administration.RESULTS AND CONCLUSION:(1)After modeling,compared with the sham operation group,the neurological function scores of the model group,Buqi Huoxue Compounds group,and Buqi Huoxue Compounds+GW4869 group were significantly increased(P＜0.01 or P＜0.05).After 7 days of intervention,the neurological function scores of the Buqi Huoxue Compounds group were significantly lower than those of the model group and Buqi Huoxue Compounds+GW4869 group(all P＜0.01).(2)The results of 2,3,5-triphenyltetrazolium chloride staining showed that cerebral infarct foci were observed in the model group,Buqi Huoxue Compounds group,and Buqi Huoxue Compounds+GW4869 group,and the cerebral infarct volume in the Buqi Huoxue Compounds group was smaller than that in the model group and the Buqi Huoxue Compounds+GW4869 group(P＜0.01).(3)The results of hematoxylin-eosin staining showed that the morphological and structural abnormalities of nerve cells in the Buqi Huoxue Compounds group and Buqi Huoxue Compounds+GW4869 group were less severe than those in the model group,but some cells still exhibited cytoplasmic agglutination and pyknosis in the Buqi Huoxue Compounds group and Buqi Huoxue Compounds+GW4869 group.(4)NanoSight analysis showed that the diameters of the isolated particles ranged from 60 nm to 300 nm,consistent with the characteristic size of exosomes.(5)Western blot results showed that the expression of p-Akt in the infarct zone and expression of CD63 and TSG101 in serum exosomes were significantly lower in the model group compared with the sham operation group(P＜0.05 or P＜0.01).Compared with the model group,the expression of p-Akt in the infarct zone and expression of CD63 and TSG101 in serum exosomes were significantly higher in the Buqi Huoxue Compounds group than in the model group(P＜0.05 or P＜0.01).However,the p-Akt expression in the infarct zone and CD63 expression in serum exosomes decreased significantly in the Buqi Huoxue Compounds+GW4869 group(P＜0.05),while TSG101 expression decreased without significant difference after the addition of GW4869.(6)To conclude,Buqi Huoxue Compounds attenuate cerebral ischemia-reperfusion injury and increase the expression of p-Akt in rats by promoting exosome secretion.
