The crosstalk between macrophages and bone marrow mesen chymal stem cells （BMSCs） plays a vital role in regulating tendon-bone healing. Based on the traditional Chinese medicine （TCM） theory that the kidney governs the bones and generates marrow， yin-nourishing and kidney-tonifying Chinese medicines can promote the osteogenic differentiation of BMSCs and the M1-to-M2 polarization of macrophages， thereby facilitating tendon-bone healing. A variety of related medicinal monomers （such as diosgenin and oleanolic acid）， extracts and effective fractions （such as artificial tiger bone powder and total flavonoids of Drynaria fortunei ）， as well as compound prescriptions （such as Liuwei dihuang pill， Xujin jiegu decoction and Duhuo jisheng decoction）， can modulate the crosstalk between macrophages and BMSCs by regulating the Wnt/β-catenin， nuclear factor kappa-B， phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin and transforming growth factor-β/Smad signaling pathways. They further exert anti-inflammatory， antioxidant and osteogenic effects to effectively accelerate tendon-bone healing. However， current evidence was limited to animal experiments exhibiting such as limitations insufficent alignment between animal models and clinical injury types， research focusing mostly on single signaling pathways， and unclear core active ingredients. Future studies shall optimize animal models and carry out large-sample randomized controlled trials， clarify the interactive networks of multiple signaling pathways， and isolate the core active substances of yin-nourishing and kidney-tonifying Chinese medicines， so as to advance the precise application of traditional Chinese medicines.

Objective To evaluate the efficacy and safety of 450 nm blue laser vaporization enucleation of the prostate in the treatment of benign prostatic hyperplasia(BPH)complicated with urinary retention, so as to promote its clinical application. Methods A retrospective analysis was conducted on the clinical data of 60 patients with BPH and urinary retention who underwent 450 nm blue laser vaporization enucleation of the prostate in our hospital during Feb. 2023 and Apr. 2024. All patients had urinary catheters indwelt preoperatively due to urinary retention. The perioperative indicators and complications were recorded. The maximum urinary flow rate(Qmax), postvoid residual(PVR), international prostate symptom score(IPSS), and quality of life score(QoL)were compared before surgery and 3 months after surgery. Results All procedures were completed successfully without conversion to transurethral resection of the prostate(TURP). No cases of severe intraoperative bleeding or transfusion were reported. The average operation time was(60.5±21.5)min, postoperative hemoglobin reduction(3.2±0.8)g/L, catheterization time(3.1±0.4)days, and hospital stay(3.2±0.4)days. No bladder perforation or urethral injury occurred. At 3 months postoperatively, Qmax [(19.2±4.9)mL/s vs.(3.5±2.3)mL/s], PVR [(50.8±20.1)mL vs.(369.2±163.2)mL], IPSS [(9.7±0.9)vs.(21.8±3.2)], and QoL [(1.4±0.5)vs.(4.9±0.1)]were significantly improved compared with preoperative values(P＜0.001). Urinary retention occurred in 2 patients after catheter removal on postoperative day 3, which was resolved one week after re-catheterization. Conclusion The 450 nm blue laser vaporization enucleation of the prostate is a safe and effective treatment for BPH complicated with urinary retention. It can significantly improve the short-term voiding function and quality of life with a low incidence of postoperative complications, demonstrating promising potential for clinical adoption.

OBJECTIVES: To evaluate the clinical efficacy of hospital-prepared Chinese medicine Feigan granules for influenza patients. This study has been registered at the International Traditional Medicine Clinical Trial Registry platform (ITMCTR2025000162). METHODS: A prospective observational study was conducted on influenza patients who visited the Fever Clinic of the First Affiliated Hospital, Zhejiang University School of Medicine between February and March 2024. Patients were divided into the observation group (Feigan granules combined with conventional Western medicine) and the control group (conventional Western medicine). Main symptoms (including fever, cough and sore throat) and secondary symptoms (including chest tightness, poor appetite, muscle soreness and dry mouth) were evaluated with traditional Chinese medicine (TCM) symptom scale on the first day of the patient's visit and the third day after treatment. The degrees of improvement in the TCM symptom scores before and after treatment were compared using paired rank-sum test, and the differences in the overall symptom efficacy index between two groups were compared using the Wilcoxon test. RESULTS: A total of 217 influenza patients were included. After treatment, the TCM symptom scores of both groups were significantly improved compared with those before treatment (all P<0.01). The median differences in the main symptom score before and after treatment in the observation and the control groups were 7 points (95%CI: 6.0-8.0) and 6 points (95%CI: 6.0-8.0), respectively. The median difference in the secondary symptom score was 3 points (95%CI: 2.0-4.0) in both groups. The median differences in the total score were 9 points (95%CI: 8.0-10.5) and 8 points (95%CI: 7.0-10.0) in the observation and control groups, respectively. In the subgroup with an initial cough score >2, the improvement rates of total score (97.06% vs. 92.59%) and secondary symptoms (92.31% vs. 85.11%) in observation group were significantly higher than those in the control group (P<0.05); while there was no significant difference in the improvement rate of the main symptoms (95.59% vs. 90.74%, P>0.05). CONCLUSIONS Feigan granules can improve the TCM syndromes of influenza patients, especially for patients with more severe cough.

Objective:To analyze the influences of coronary angiography(CAG)of transradial artery on the success rate,radiation dose and safety in elderly patients with coronary heart disease(CHD).Methods:This study conducted a prospective study.A total of 150 elderly CHD patients who admitted to Heilongjiang Rad Cross Sengong General Hospital from November 2022 to November 2023 were selected,and they were randomly divided into three groups using a random number table,which included the femoral artery group(n=50),radial artery group(n=50),and ulnar artery group(n=50).The femoral artery group underwent CAG by using the femoral artery approach,and the radial artery group underwent CAG by using the radial artery approach,and the ulnar artery group underwent CAG by using the ulnar artery approach.The CAG success rate and CAG indicators[dosage of contrast agent,X-ray exposure time,time of conducting puncture,corrected TIMI frame count(CTFC)]were compared among the three groups.The radiation-related parameters[cumulative dose(CD),dose-area product(DAP)]also were compared among three groups.The patients'comfort degrees of three groups were assessed by adopting General Comfort Questionnaire(GCQ)at three time points(pre-CAG,during CAG,at the 12th hour post-CAG).In addition,the complications of three groups were recorded.Results:The numbers of success angiography were respectively 47 cases,48 cases and 46 cases in femoral artery group,radial artery group and ulnar artery group,and the success rates of them were respectively 94.00%(47/50),96.00%(48/50)and 92.00%(46/50),without statistically significant differences among three groups(P>0.05).There were not significant differences in the dosage of contrast agent,X-ray exposure time,time of conducting puncture,CTFC,CD and DAP among three groups(P>0.05).In the GCQ scores,the scores pre-CAG of all three groups were highest,followed by those at the 12th hour post-CAG,and then,those during CAG were lowest,which appeared a trend of rise after decline.The total incidence of complication was lowest(6.25%)in the radial artery group,followed by the ulnar artery group(10.87%),and that(21.28%)of the femoral artery group was the highest,but there was not statistically significant difference in that among three groups(P>0.05).Conclusion:The CAG success rates of the radial artery,femoral artery and ulnar artery are similar,and there is not significant difference in radiation dose.However,compared with CAG of femoral artery and ulnar artery,the CAG of radial artery has higher safety,and higher comfort degree at the same time.

Objective:To investigate the feasibility and advantages of 30°reverse trendelenburg combined with semi-prone position in single-port thoracoscopic surgery for lung cancer.Methods:This study is a prospective, randomized controlled trial. Between October 2022 and December 2023, patients with lung cancer who met the inclusion and exclusion criteria were prospectively enrolled at the Department of Thoracic Surgery, the First Affiliated Hospital of Zhengzhou University,and randomized using a simple randomization design to generate a random number table. Patients were allocated in a 1∶1 ratio to either the modified positioning group (30°reverse trendelenburg combined with semi-prone position) or the conventional positioning group (lateral decubitus position). Comparative analysis was performed on feasibility metrics including operative time, postoperative pain scores, surgeon and assistant fatigue levels, number of lymph nodes dissected, duration of postoperative chest tube drainage, and postoperative hospital stay. Inter-group comparisons were conducted using independent sample t-tests, χ2 tests or Kruskal-Wallis. Results:A total of 211 patients were included.The modified positioning group comprised 105 patients (58 males, 47 females) with an age of (56.2±10.3）years (range: 23 to 74 years). The conventional positioning group included 106 patients (55 males, 51 females) with an age of (57.8±11.7）years (range: 21 to 76 years). All patients underwent successful single-port thoracoscopic lung cancer surgery without severe perioperative complications. No statistically significant differences were observed between groups in operative time ((98±34) minutes vs. (114±36) minutes, t=-1.642, P=0.221), number of lymph nodes dissected (13.4±2.5 vs. 12.8±3.2, t=0.702, P=0.763), postoperative chest tube duration ((4.3±1.5) days vs. (5.1±1.8) days, t=-1.348, P=0.247), or postoperative hospital stay ((5.0±1.2) days vs. (5.6±1.5) days, t=-0.831, P=0.682). The modified positioning group demonstrated significantly lower postoperative day 1 pain scores on the visual analog scale (3.1±2.0 vs. 4.6±1.9, t=-4.321, P=0.027) and postoperative surgeon-reported fatigue scores (primary surgeon: 13.6±2.5 vs. 18.5±3.3, t=-6.963, P=0.002; assistant surgeon: 12.1±2.0 vs. 17.1±3.1, t=-6.133, P=0.003) compared with the conventional group, with all differences reaching statistical significance. Conclusions:The application of 30°reverse trendelenburg combined with semi-prone position during single-port thoracoscopic lung cancer surgery is both safe and feasible. Compared with the conventional lateral decubitus position, this modified positioning demonstrates significant advantages in reducing postoperative pain and alleviating surgical team fatigue (including both primary and assistant surgeons).

Objective To investigate the effect of triptolide(TPL)on renal interstitial fibrosis in mice with unilateral ureteral obstruction(UUO)and its mechanism.Methods Six male C57BL/6J mice were randomly selected as the sham group,and 12 mice with UUO modeling were randomly divided into the model group(UUO)and the triptolide group(TPL).Changes in serum creatinine(SCr),blood urea nitrogen(BUN),and body weight were compared among the groups.Renal tissue specimens were collected at 14 d after UUO for HE and Masson staining.Immunohistochemistry staining was performed to observe the expression of α-smooth muscle actin(α-SMA)and fibronectin(Fn)in kidney tissues.Western blotting analysis was used to detect the protein expression levels of nucleotide combined with structure of oligomerization domain receptor protein 3(NLRP3),GSDMD,cGSDMD,IL-1β and IL-18.Results At week 1,the body weight of mice in the UUO and TPL groups significantly decreased compared with that in the sham group(P＜0.05).Body weight reduced in the TPL group compared with that in the Sham group at week 2(P＜0.01).There was no significant difference in body weight between the TPL and UUO groups.BUN levels did not differ significantly between the three groups.Compared with the sham group,the SCr level in the UUO group significantly increased[(15.680±1.508)μmol/L](P＜0.01).A reduction in SCr level was observed following TPL administration[(12.550±3.004)μmol/L](P＜0.05).HE staining showed that the renal tubules of mice in the UUO group were significantly dilated and atrophic,with interstitial edema and increased inflammatory cell infiltration,while the pathological damage of renal tissues was significantly alleviated after TPL treatment.Masson staining revealed that interstitial collagen deposition significantly increased in the UUO group(36.350±5.183)％(P＜0.01)and reduced after TPL administration(20.820±3.290)％(P＜0.01).Immunohistochemistry results demonstrated that the IOD levels of α-SMA(1.233±0.045)and Fn(1.337±0.045)were higher in UUO group mice than in the sham group,while the IOD levels of α-SMA(1.047±0.025)and Fn(1.113±0.021)were lower in the TPL group than in the UUO group(P＜0.05).Western blotting analysis indicated that the expression levels of NLRP3,cGSDMD,IL-1β and IL-18 in the UUO group mice were higher than those in the sham group,while the protein expression levels of the above-mentioned indicators significantly decreased after TPL treatment(P＜0.05).Conclusion TPL ameliorates renal interstitial fibrosis in mice with UUO by inhibiting NLRP3-mediated pyroptosis.
