Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.

Xiang thinking is the key way of thinking to construct the life model of human body in traditional Chinese medicine （TCM）， and the theory of ascending and descending of qi movement is an important manifestation of xiang thinking in the theory of TCM. Based on the theory of qi movement， this paper interpreted the mechanism of ischemic stroke through the perspective of xiang thinking "earth weakness - wood constraint - fire hyperactivity"， as "earth weakness in the central and dampness accumulated to phlegm" "wood constraint and stirring wind led to blood stasis" and "fire hyperactivity and fire toxin showed flaming upward" due to disorder of qi movement. Combined with the "xiang of medicinal properties and therapy methods" to discuss the treatment and prescriptions of ischaemic stroke， applying wind medicinals to elevate ji-earth （己土） and yi-wood （乙木）， so that phlegm and stasis can be eliminated， and cold medicinals to descend jia-wood （甲木） and wu-earth （戊土） so that fire toxin can be cleared， with a view to restore ascending and descending of qi movement for ischaemic stroke.

Objective To investigate the effect of blue light on the dioptric development of the eyes of lens-induced myopia(LIM)guinea pigs.Methods Three-week-old trichromatic guinea pigs were randomly divided into three groups:control group,white light LIM(WL)group,and blue light LIM(BL)group(420 nm LED light,with an illuminance of 700 lx);guinea pigs in the latter two groups wore-10.00 D lenses in their right eyes to induce myopia.All guinea pigs under-went a 12 h light/12 h dark treatment cycle.Before and 2,4 weeks after the intervention,the diopter,axial length,retinal thickness and choroidal thickness were measured in all groups.After 4 weeks of intervention,the corneal fluorescent stai-ning and retinal Hematoxylin and Eosin(HE)staining were conducted.Results Compared with the control group,from week 0 to week 2 of the intervention(changes in weeks 0-2),the eyes in the WL group drifted(-2.22±1.28)D towards myopia,the axial length lengthened by(0.40±0.05)mm,and the retinal and choroidal thicknesses reduced by(-7.42± 7.04)μm and(-6.29±4.66)μm,respectively;compared with the WL group,in the BL group,the eyes drifted toward hyperopia by(0.48±1.16)D,the axial length increased by(0.20±0.10)mm,and retinal and choroidal thicknesses in-creased by(1.36±7.46)μm and(8.05±8.08)μm,respectively(all P＜0.05).From week 2 to week 4(changes in weeks 2-4),compared with the control group,the diopter in the WL and BL groups progressed towards myopia,with changes of(-4.64±0.50)D and(-2.11±2.02)D,respectively(both P＜0.05);the axial length lengthened,and reti-nal and choroidal thicknesses reduced in the WL group,with changes of(0.44±0.06)mm,(-7.35±5.87)μm and(-4.84±2.61)μm,while the choroidal thickness and the retinal thickness decreased in the BL group,with changes of(-0.33±5.95)μm and(-4.78±4.96)μm,respectively.Observations of corneal fluorescence staining and retinal HE staining indicated that prolonged blue light exposure could lead to damage to corneal and retinal cells.Conclusion Blue light may influence the development of myopia through choroid-related mechanisms,but its inhibitory effect is not positive-ly correlated with time.Prolonged exposure to blue light can damage the cornea and retina,thereby reducing the inhibitory effect.

ObjectiveBy starting with the combination of Os Draconis， Bupleuri Radix， and Ostreae Concha， the role of mineral medicine Os Draconis in the combination of the Bupleuri Radix-containing tri-herbal medicines was preliminarily explored from the perspective of supramolecular system formation. Method① The appearance and Tyndall phenomenon of single decoction of Os Draconis， Bupleuri Radix， and Ostreae Concha， as well as co-decoction of Bupleuri Radix-Os Draconis， Bupleuri Radix-Os Draconis-Ostreae Concha， and Bupleuri Radix-Ostreae Concha were observed， and the average particle size， dispersion coefficient， and Zeta potential of suspension particles in each decoction were determined. The micromorphology of supramolecular structures was observed by scanning electron microscope （SEM）. ② The pH of different compatibility systems， liquid viscosity coefficient， liquid surface tension， freeze-dried powder yield rate， and other physical properties were determined， and the interaction of different compatibility systems was detected by infrared absorption spectroscopy （FTIR） and UV-visible spectrophotometry （UV-Vis）. ③ The composition and content difference of different compatible systems were determined by high-performance liquid chromatography （HPLC） and ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry （UPLC-Q-TOF-MS）. ResultCompared with the single decoction， the co-decoction had more obvious turbidity and Tyndall phenomenon. The particles in the co-decoction suspension were smaller and more evenly distributed， and the Zeta potential was reduced， indicating a more stable system. Under SEM， Bupleuri Radix was irregularly lamellar， and Bupleuri Radix-Os Draconis and Bupleuri Radix-Os Draconis-Ostreae Concha were mainly spherical nanoparticles. Bupleuri Radix-Ostreae Concha was irregularly lamellar， with a small number of spherical nanoparticles. The pH of the single decoction of Bupleuri Radix and co-decoction increased， and the viscosity coefficient increased. The liquid surface tension decreased. The freeze-dried powder yield rate of the Bupleuri Radix-Os Draconis co-decoction was the highest， followed by Bupleuri Radix-Ostreae Concha decoction and Bupleuri Radix-Os Draconis-Ostreae Concha decoction， and the yield rate of Bupleuri Radix single decoction was the lowest. The main change of FTIR was the stretching vibration of -OH， and the co-decoction moved to the low-frequency direction obviously. UV-Vis showed that the maximum absorption occurred at 295.8 nm for all groups， and the absorption intensity was different （Bupleuri Radix-Os Draconis>Bupleuri Radix-Os Draconis-Ostreae Concha>Bupleuri Radix-Ostreae Concha>Bupleuri Radix）. The components of Bupleuri Radix were used as the indexes， and the content of methanol extract determined by HPLC was higher than that of water extract， and the components of Bupleuri Radix single decoction were mainly saikosaponin a （SSa） and saikosaponin c （SSc）， which were slightly higher after co-decoction compatibility. UPLC-Q-TOF-MS could identify 37 compounds in both single decoction and co-decoction. ConclusionThe combination of Bupleuri Radix， Os Draconis， and Ostreae Concha can form a smaller， more uniform， and stable nano-sized supramolecular system， which is conducive to the dissolution of the main components of Bupleuri Radix， and the Os Draconis contributes the most in this process.

Myogenous temporomandibular disorder(M-TMD)is one of the main subtypes of temporomandibular dis-order(TMD)and typically manifests as masticatory myofascial pain;the incidence of TMD has been increasing annually in recent years.Botulinum toxin type A(BTX-A)is a potent neurotoxin produced by Clostridium botulinum.BTX-A in-hibits the release of acetylcholine from the presynaptic membrane,thereby blocking neuromuscular junction signaling.The noncosmetic application of BTX-A in the oral and maxillofacial regions is a prominent research topic.In recent years,an increasing number of studies have focused on the application of BTX-A in the treatment of M-TMD.The re-sults of a literature review revealed that an appropriate dose(10-50 U unilaterally)of BTX-A administered in a single in-jection into the masticatory muscles can effectively treat myalgia over a period of 3-6 months.Common adverse effects,such as masticatory weakness and facial paralysis,are transient and can be avoided by standardized injection tech-niques.However,there is a lack of standardized guidelines for injection techniques in clinical practice.

AIM:Bone morphogenetic protein 7(BMP7)reduces the expression of Yes-related protein 1(YAP1)by down-regulating Ajuba level and decreasing extracellular matrix(ECM)deposition.This study aimed to inves-tigate the influence of these factors on modifying the degree of renal fibrosis in rats with diabetic nephropathy.METH-ODS:Eighteen Sprague-Dawley(SD)rats were randomly divided into three groups:the normal control(NC)group,the diabetes mellitus(DM)group,and the DM group treated with BMP7 overexpressing adeno-associated virus(DM+rAAV-BMP7).Each group consisted of six rats.Diabetic kidney disease(DKD)was established in the DM and DM+rAAV-BMP7 groups by injecting 55 mg/kg streptozotocin(STZ)via the tail vein.NRK-52E cells were divided into three groups:the normal glucose(NG)group,the high glucose(HG)group,and the high glucose group treated with recombinant hu-man BMP7(HG+rhBMP7)group.Pathological changes in renal tissues were observed using hematoxylin and eosin(HE)and Sirius red staining.Immunohistochemical staining was performed to examine the expression sites of Ajuba and YAP1 in the renal cortex.Western blot analysis was conducted to determine the expression levels of BMP7,Ajuba,YAP1,colla-gen type Ⅲ(Col-Ⅲ),and fibronectin(FN)in the rat renal cortex and NRK-52E cells.RT-qPCR was used to measure the mRNA levels of Ajuba and YAP1 in the rat renal cortex.RESULTS:Biochemical indices revealed significantly ele-vated levels of blood glucose,serum creatinine,triglycerides,total cholesterol,and 24-hour urinary protein in the DM group compared to the NC group(P<0.05).In the DM+rAAV-BMP7 group,the levels of serum creatinine,24-hour uri-nary protein,triglycerides,and total cholesterol were lower than those in the DM group(P<0.05).Pathological staining demonstrated that the renal interstitium of the DM group exhibited inflammatory cell infiltration,fibrous tissue,collagen fi-ber deposition,disordered renal tubule arrangement,atrophy,and vacuolar degeneration,which were ameliorated in the DM+rAAV-BMP7 group.Immunohistochemistry revealed that Ajuba and YAP1 were mainly expressed in the cytoplasm and nucleus,with high expression in the cytoplasm of the DM group,which was significantly decreased in the DM+rAAV-BMP7 group.Western blot results indicated that the protein levels of FN,Col-Ⅲ,Ajuba,and YAP1 were up-regulated in the DM and the HG groups(P<0.05),but significantly down-regulated in the DM+rAAV-BMP7 group(P<0.05).RT-qP-CR results demonstrated that the mRNA levels of Ajuba and YAP1 were higher in the DM group and significantly lower in the DM+rAAV-BMP7 group(P<0.05).CONCLUSION:The overexpression of BMP7 can ameliorate renal fibrosis in rats with DKD.This effect is likely mediated by the down-regulation of Ajuba,reduction of YAP1 expression,and subse-quent inhibition of ECM deposition.

Objective To observe changes of CT quantitative indexes in patients with untreated chronic obstructive pulmonary disease(COPD)and relationships with pulmonary function indicators.Methods Totally 99 patients with untreated COPD were retrospectively enrolled.According to the degrees of airflow obstruction,the patients were divided into group A(GOLD grade 1 with mild obstruction,n=36),group B(GOLD 2 with moderate obstruction,n=37)and group C(GOLD 3 or 4 with obvious obstruction,n=26).The results of chest CT and pulmonary function tests conducted at the first diagnosis and the follow-up,as well as their correlations were analyzed.CT quantitative indicators included the whole lung volume,low-attenuation areas less than-950 percentage(LAA％),total number of vessels per 1 cm2 of lung surface area(Ntotal/LSA),total number of vessels with area less than 5 mm2 per 1 cm2 of lung surface area(N＜5mm2/LSA),the square root of the wall area of a hypothetical airway with a 10 mm internal perimeter(Pi10),the entire volume,wall thickness and wall area percentage(WA％)of airway wall,etc.,while results of pulmonary function tests included the forced expiratory volume in one second(FEV1)after administration of a bronchodilator,forced vital capacity(FVC),the ratio FEV1/FVC and FEV1 expressed as percent predicted(FEV1％).Results Compared with those at the first diagnosis,the follow-up results of FVC,FEV1,FEV1/FVC,Ntotal/LSA and N＜5mm2/LSA were lower,whereas LAA％,Pi10 and entire volume of airway were all higher in each group(all P＜0.05).Compared with those in group A,group B and C had decreased LAA％and increased Pi10,and the magnitude increased with the severity of airflow obstruction(all P＜0.05).LAA％,Pi1o and entire volume of airway wall were negatively correlated with pulmonary function indicators(all P＜0.05),while Ntotal/LSA and N＜5 mm2/LSA were positively correlated with pulmonary function indicators(all P＜0.05).Conclusion CT quantitative parameters,including LAA％,Ntotal/LSA,N＜5mm2/LSA,Pi10 and entire volume of airway wall were related to pulmonary function,which might reflect the longitudinal changes of airways and blood vessels in COPD patients.

Myeloid neoplasms (MNs) belong to a group of hematological malignancies characterized by the abnormal biological functions of hematopoietic stem progenitor cells. The abnormal immune and hematopoietic microenvironment of patients with MN interact with malignant clonal hematopoietic stem cells, promoting the occurrence and development of their diseases. MN large granular lymphocyte proliferation (MN-LGLP) is a special and rare clinical phenomenon in this type of disease. Currently, research on this disease in domestic and international cohorts is limited. This study analyzes the clinical and laboratory characteristics of this type of patient and explores the impact of LGLP on the clinical characteristics and survival of patients with MN. Patients with MN-LGLP are prone to neutropenia and splenomegaly. The presence of LGLP is not a risk factor affecting the survival of patients with MN-LGLP. STAG, ASXL1, and TET2 are the most common accompanying gene mutations in MN-LGLP, and patients with MN-LGLP and STAG2 mutations have poor prognoses.

Objective To explore the effects of monocular deprivation(MD)on the expression of astrocytes in the superior colliculus,hippocampus,and visual cortex in mice during the critical period of visual development.Methods Eighteen C57BL/6J mice were randomly divided into the normal control group(CON group)and the MD group,with 9 mice in each group.Mice were bred under the 12 h/12 h dark/light conditions.Mice in the CON group received no treat-ment,while mice in the MD group underwent MD of the right eye on postnatal day 27,and the tissue was removed after 7 days.The mRNA and protein expression levels of glial fibrillary acidic protein(GFAP)in the superior colliculus,hippo-campus and visual cortex of mice in the two groups were detected using the real-time reverse transcription quantitative pol-ymerase chain reaction(RT-qPCR)and Western blot,respectively.The number of astrocytes labeled by GFAP and central nervous system specific protein β(S100β)in the superior colliculus,hippocampus and visual cortex of mice in the two groups was detected using the immunofluorescence staining.Results RT-qPCR and Western blot results showed that compared with the CON group,the mRNA and protein expression levels of GFAP in the superior colliculus,hippocampus(CA1,CA3 and dentate gyrus)and visual cortex of mice in the MD group decreased,and the differences were statistically significant(all P＜0.05).The immunofluorescence staining results showed that compared with the CON group,the number of GFAP and S1OOβ co-labeled astrocytes in the superior colliculus,hippocampus(CA1,CA3 and dentate gyrus)and visual cortex of mice in the MD group decreased,and the differences were statistically significant(all P＜0.05).Conclusion MD of mice during the critical period of visual development can result in a decrease in the number of astrocytes in the supe-rior colliculus,hippocampus and visual cortex.
