Objective To investigate the therapeutic effects of bone marrow mesenchymal stem cells (BMSCs) for radiation-induced lung injury (RILI) and the underlying mechanism. Methods Forty-five healthy adult male C57BL/6 mice were randomly divided into control, model, and BMSCs groups. The model and BMSCs groups received a single irradiation dose of 20 Gy to the chest, while the control group did not receive X-ray irradiation. For the BMSCs group, an injection of 1 × 10⁶ BMSCs cells was administered via the tail vein within 6 h after irradiation. In the 5th week, the lung tissue was taken to observe pathological changes with HE staining; examine the expression of the inflammatory factors interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) with immunohistochemical staining; observe the polarization of macrophages with immunofluorescence staining; and measure the expression of the epithelial-mesenchymal transition markers E-cadherin, N-cadherin, and vimentin proteins by Western blot. Results After radiation, the model group developed pulmonary vasodilation and congestion with septal thickening and inflammatory cell infiltration, and these changes were markedly reduced in the BMSCs group. The model group showed significantly down-regulated expression of IL-6 and TNF-α compared with significantly increased levels in the model group (P < 0.01, P < 0.05). Treatment with BMSCs significantly increased the polarization of lung macrophages towards the M2 type, while significantly decreasing the abnormally increased N-cadherin and vimentin levels in RILI mice (P < 0.05, P < 0.01). Conclusion BMSCs have therapeutic effects for RILI mice, which may be through promoting macrophage polarization from M1 to M2.

Objective To explore the application value of stage rehabilitation intervention under the Health action process approach(HAPA)model(SRI-HAPAM)combined with tranexamic acid(TXA)in elderly patients with femoral neck fracture(FNF)undergoing total hip arthroplasty(THA).Methods Elderly FNF patients with unilateral THA in the First Affiliated Hospital of Wenzhou Medical University from December 2022 to June 2023 were enrolled.According to the random number table method,the patients were divided into routine nursing(RN)group and TXA+SRI-HAPAM group.The RN group received conventional treatment after surgery,and the TXA+SRI-HAPAM group received TXA combined with SRI-HAPAM after surgery.The bleeding indexes[hidden blood loss(HBL),explicit blood loss(EBL)and blood transfusion volume(BTV)],and the levels of hemoglobin(Hb),C-reactive protein(CRP)and D-dimer(DD)were compared between the two groups at 24 h after surgery.The hip function[joint deformity(JD),joint function(JF),joint pain(JP),joint motion(JM)and total hip function(THF)],anxiety and depression[self-rating anxiety scale and self-rating depression scale],satisfaction with care,and complications were compared between the two groups at 3 months after surgery.Results A total of 100 elderly patients with unilateral THA due to FNF were included in the study,including 54 in the TXA+SRI-HAPAM group and 46 in the RN group.Before operation,there was no significant difference in Hb,CRP,DD,JD,JF,JP,JM,THF and SAS between the two groups(P>0.05).At 24 hours after operation,Hb decreased in the two groups,while CRP and DD increased(P<0.05),and the decrease in Hb and the increase in CRP and DD,as well as HBL,EBL and BTV in the TXA+SRI-HAPAM group,were lower than those in the RN group(P<0.05).At 3 months after operation,JD,JF,JP,JM and THF in both groups increased compared with those before operation,while SAS and SDS decreased compared with those before operation(P<0.05),and the functional scores of JD,JF,JP,JM and THF in the TXA+SRI-HAPAM group were significantly higher than those in the RN group,and the scores of SAS and SDS were lower than those in the RN group(P<0.05).3 months after surgery,the nursing satisfaction of the TXA+SRI-HAPAM group was significantly higher than that of the RN group,and the total complication rate was lower than that of the RN group(P<0.05).Conclusion Compared the Routine nursing,TXA combined with SRI-HAPAM more effectively promotes postoperative recovery in patients with THA.

It is believed that the endoscopic manifestations of interstitial cystitis/bladder pain syndrome （IC/BPS） such as extensive bleeding and Hunner's ulcers as well as its recurrent and prolonged condition are in line with the characteristics of sores and ulcers in traditional Chinese medicine （TCM）， and the treatment can be referred to TCM theory of sores and ulcers. The mechanism of IC/BPS is characterized by root deficiency and branch excess. The root cause is deficiency of the spleen and kidney qi， while the manifesting factors are dampness-heat and blood stasis. The treatment is based on the principles of promoting and supplementing， combining with resolving therapy， so that the symptoms could be relieved by promoting blood circulation and clearing heat， unblocking the collaterals and relieve pain. In clinical practice， modified Neituo Shengji Powder （内托生肌散） was commonly used to boost qi and invigorate blood， expel swollen sore and express toxin； combining with Sijunzi Decoction （四君子汤） or Suoquan Pill （缩泉丸） based on specific symptoms to strengthen the spleen and kidneys， thereby reinforcing healthy qi； according to concurrent symptoms like blood stasis， dampness heat， prescription with Sanleng （Cyperus rotundus）， Ezhu （Curcuma aromatica Salisb） to invigorate blood and dissolve stasis， or Yiyiren （Coix lacryma-jobi）， Zexie （Alisma plantago-aquatica） to clear heat and drain dampness.

BACKGROUND:Gold nanoparticles are of great significance in the development of multifunctional transdermal drug delivery systems.Smaller gold nanoparticles can penetrate the dermis through the intercellular pathway,but are limited to their easy agglomeration and colloidal morphology,which makes it difficult to exert effects on low delivery efficiency. OBJECTIVE:To develop an ultrasound-optimized hydrogel delivery system by combining phase change nanodroplets with bio-adhesive hydrogel for percutaneous delivery of gold nanoparticles. METHODS:The ultrasound-responsive nanodroplets loaded with gold nanoparticles were prepared by the emulsion solvent evaporation method and loaded into the polydopamine-modified methylacryloyl gelatin hydrogel to prepare a composite hydrogel scaffold.The structure and chemical composition of the ultrasound-responsive nanogold carrier were characterized.The microstructure,porosity,permeability,rheology,in vitro hemostasis,and antibacterial properties of the composite hydrogel were characterized.The cell compatibility of the hydrogel scaffold was evaluated by live/dead staining,and the optimization effects of low-intensity pulsed ultrasound on the permeability,porosity,and mechanical properties of hydrogel were evaluated. RESULTS AND CONCLUSION:(1)Transmission electron microscopy and ultraviolet-visible spectroscopy proved the successful construction of nanogold carriers.The particle size and potential results demonstrated that the synthesized nanoscaled ultrasonic responsive carrier had good stability.(2)Live/dead cell staining proved that the prepared composite hydrogel scaffold had certain biocompatibility.(3)Scanning electron microscopy exhibited that the prepared composite hydrogel scaffold had a porous network structure,and numerous pores of about 2 μm appeared inside the macropores after the addition of nanodroplets and ultrasonic irradiation.The permeability experiment displayed that low-intensity pulsed ultrasound could optimize the porosity and permeability of hydrogel materials.The hemostatic performance of the composite hydrogel scaffold was better than that of the hemostatic sponge and polydopamine@methylacrylylated gelatin hydrogel scaffold.Under the irradiation of low-intensity pulsed ultrasound,the composite hydrogel scaffolds had good antioxidant effects and antibacterial properties.(4)Thermal imaging results manifested that gold nanoparticles were encapsulated in ultrasound-responsive nanobubbles,and more uniform dispersion could be obtained under ultrasonic excitation.(5)The results of the mechanical property test demonstrated that the storage modulus of the hydrogel increased before and after loading gold nanoparticles-nanodroplets,which showed stronger mechanical properties.The elongation at break was 122%,and the ductility was better than that without gold nanoparticles-nanodroplets(P<0.05).(6)These findings indicate that the composite hydrogel scaffold has good biocompatibility,antibacterial property,oxidation resistance,and hemostatic effect.

Ulcerative colitis （UC） is a chronic， non-specific inflammatory bowel disease. The pathogenesis of this disease is complex and is attributed to multiple factors. Intestinal mucosal barrier damage is the basic pathological change of UC， and intestinal flora disorder is one of the important characteristics of UC. Intestinal flora plays a key role in the pathological process of UC by regulating intestinal mucosal immunity and inflammatory response to repair the damaged intestinal mucosal barrier. At present， western medicine has the advantages of rapid action onset and significant short-term efficacy， but the curative effect of long-term use is not good， accompanied by many adverse reactions， causing great physical and mental pain to patients. Therefore， it is urgent to explore new treatment methods with definite long-term efficacy and mild adverse reactions. A large number of studies have shown that Chinese medicine can regulate intestinal flora through multiple targets in an all-around way， restore the homeostasis of the flora， and repair the damaged intestinal mucosal barrier， thereby inhibiting the progression of UC. Numerous studies have shown that the active components， monomers， and compounds of Chinese medicine can effectively antagonize UC by regulating the intestinal flora to improve the intestinal mucosal immunity， reduce the inflammatory response of the intestinal mucosa， and restore the normal physiological function of the intestinal mucosal barrier， providing a new strategy for UC prevention and treatment. Although there are some studies of the regulation of intestinal flora by Chinese medicine to prevent and treat UC， those studies have the shortcomings of systematic and comprehensive inadequacy. Therefore， based on the research status of UC， intestinal flora， and Chinese medicine treatment， this study reviewed the relationship between intestinal flora and UC and clarified the key role of intestinal flora in the occurrence and development of UC. At the same time， this paper comprehensively summarized the Chinese medicine that targeted the regulation of intestinal flora for the treatment of UC in the past five years to provide new strategies and ideas for UC treatment.

Ulcerative colitis （UC） is a chronic inflammatory bowel disease with complex etiology. The pathogenesis of this disease， due to a combination of factors， is complex and has not yet been elucidated. Among them， intestinal mucosal barrier damage is the basic pathological change of UC. As a non-destructive response of cells， autophagy regulates intestinal mucosal immunity， inflammation， oxidative stress， and bacterial homeostasis through degradation and reabsorption to actively repair damaged intestinal mucosal barrier， exerting a key role in the occurrence and development of UC. The disease is mainly treated clinically with aminosalicylic acid preparations， glucocorticoids， and immunosuppressants. Western medicine treatment of the disease has a fast onset of effect， and the short-term efficacy is definite， but the long-term application is easy to be accompanied by more adverse reactions. Moreover， some drugs are expensive， bringing great physical and mental pain and economic burden to patients. Therefore， it is urgent to explore new therapies with stable efficacy and mild adverse effects. In recent years， a large number of studies have shown that Chinese medicine can regulate autophagy of the intestinal mucosa with multiple targets and effects and repair the intestinal mucosal barrier function， thereby inhibiting the development of UC. Many experiments have shown that the active ingredient or monomers and compound formulas of Chinese medicine can improve the immunity of the intestinal mucosa， inflammation， oxidative stress， and flora by regulating the level of autophagy to maintain the normal function of the intestinal mucosal barrier to effectively intervene in UC， providing a new measure for the prevention and treatment of UC. However， there is a lack of systematic review of Chinese medicine in regulating the level of autophagy in the intestinal mucosa for the prevention and treatment of UC. Therefore， based on the current research on UC， autophagy process， and Chinese medicine treatment， this article reviewed the relationship of autophagy and its key target proteins with UC to clarify the key role of autophagy in UC production and systematically summarized Chinese medicines targeting the regulation of autophagy to treat UC in recent years to provide new ideas for the treatment and drug development of UC.

Background: Overactive bladder (OAB) is a prevalent condition that substantially degrades patient quality of life. Acupuncture is recognized as an effective therapeutic approach for various urological diseases. However, there is limited evidence validating the effectiveness and safety of acupuncture for OABs. Objective: To assess the therapeutic efficacy of acupuncture for OAB and to investigate the potential mechanisms by analyzing its effects on relevant urinary biomarkers. Methods: This is a randomized, participants and outcome assessors blinded, sham acupuncture controlled trial. A total of 110 patients with OABs will be randomly divided in a 1:1 ratio between the acupuncture and sham acupuncture groups. Participants in the acupuncture group will undergo 30-min authentic acupuncture, while their counterparts in the sham acupuncture group will undergo sham acupuncture needling non-acupoints superficially three times weekly for a duration of 8 weeks. The two co-primary outcomes will be the change in the mean number of micturitions per 24 h from baseline to the end of the 8-week treatment and 20-week follow-up. The secondary outcomes will encompass the change in Overactive Bladder Symptom Score, Overactive Bladder Questionnaire Short Form, and average 24 h values of urgency, daytime micturition, nocturia, and mean volume voided per micturition from baseline to weeks 8 and 20. Urinary nerve growth factor, brain-derived neurotrophic factor, and monocyte chemoattractant protein-1 levels will be measured at baseline and week 8. Adverse events will also be documented. Discussion The results of this trial will provide evidence for the effectiveness and safety of acupuncture in the management of OAB.

Objective:To investigate clinical efficacy of parasacral perforator flap (PPF) on postoperative wound healing in pilonidal sinus diseases (PSDs).Methods:The surgery steps were as follows: (1) To preoperatively detect parasacral perforator arteries with the handhold Doppler probe and mark them; (2) To remove the infected and necrotic tissues of PSDs completely; (3) To design the PPF according to the wound size and the parasacral perforator arteries' localization; (4) To harvest the flap from the gluteus maximus muscle surface and transfer it to the wound without tension.
