Objective: To investigate the efficacy，safety and feasibility of regional lymph node dissection in laparoscopic radical surgery for bladder cancer under the guidance of indocyanine green fluorescence imaging. Methods: A total of 30 patients with muscle invasive bladder cancer (T2/T3NxM0) who volunteered to enter the clinical trial were randomly divided into the indocyanine green imaging guided laparoscopic regional lymph node dissection group (n=15) and the standard pelvic lymph node dissection group (n=15).The number of positive lymph nodes，operation time，intraoperative bleeding volume，incidence of lymph leakage，and tumor recurrence and metastasis rate 2-year after surgery were collected. Results: The number of positive lymph nodes was (4.20±1.66) and (4.60±1.72) respectively in the indocyanine green and standard groups，with no statistically significant difference (P>0.05).There were no statistically significant difference in the tumor recurrence and metastasis rates 2-year after surgery between the two groups (P>0.05).However，the indocyanine green group had shorter operation time，less intraoperative bleeding volume，and lower incidence of lymphatic leakage than the standard group (P<0.05). Conclusion: Indocyanine green fluorescence imaging guided laparoscopic lymph node dissection has comparable clinical efficacy to standard lymph node dissection，but with fewer complications.

Based on the theory of the five-body constituents from Huangdi Neijing (Yellow Emperor's Internal Classic), the approach and methods of acupuncture for facial aging are explored. Acupuncture for facial aging can be guided by the concept of the five-body constituents, targeting the facial "skin, flesh, vessels, tendons, and bones", and utilizing five different types of needles-facial needles, needle knives, filiform needles, retaining needles, and elongated needles and filiform needles-to maximize their respective advantages in treating facial aging. Facial needles are applied to the "skin" by selecting facial acupoints or local ashi points (at wrinkle or pigmentation sites). Needle knives are used for the "flesh" to perform longitudinal dredging and transverse dissection of the facial muscle layers. Filiform needles target the "vessels" with needling at Renying (ST9) to improve facial complexion. Retaining needles act on the "tendons" with needling from Taiyang (EX-HN5) to Xiaguan (ST7), and Jiache (ST6) to Daying (ST5), using clockwise twisting to generate a retaining needle sensation and lifting to achieve an overall facial lifting effect.

The small-molecule alkaloid halofuginone (HF) is obtained from febrifugine. Recent studies on HF have aroused widespread attention owing to its universal range of noteworthy biological activities and therapeutic functions, which range from parasite infections and fibrosis to autoimmune diseases. In particular, HF is believed to play an excellent anticancer role by suppressing the proliferation, adhesion, metastasis, and invasion of cancers. This review supports the goal of demonstrating various anticancer effects and molecular mechanisms of HF. In the studies covered in this review, the anticancer molecular mechanisms of HF mainly included transforming growth factor-β (TGF-β)/Smad-3/nuclear factor erythroid 2-related factor 2 (Nrf2), serine/threonine kinase proteins (Akt)/mechanistic target of rapamycin complex 1(mTORC1)/wingless/integrated (Wnt)/β-catenin, the exosomal microRNA-31 (miR-31)/histone deacetylase 2 (HDAC2) signaling pathway, and the interaction of the extracellular matrix (ECM) and immune cells. Notably, HF, as a novel type of adenosine triphosphate (ATP)-dependent inhibitor that is often combined with prolyl transfer RNA synthetase (ProRS) and amino acid starvation therapy (AAS) to suppress the formation of ribosome, further exerts a significant effect on the tumor microenvironment (TME). Additionally, the combination of HF with other drugs or therapies obtained universal attention. Our results showed that HF has significant potential for clinical cancer treatment.

OBJECTIVE Notoginseng Radix et Rhizoma residues were used as raw material to compare the difference in the im-pact of different probiotics and composite probiotic on various indicator components through probiotic fermentation,aiming to explore the optimal fermentation process.METHODS The fermentation process was optimized using single factor and Box-Behnken response surface methodology,and the antioxidant capacity of the fermentation product was assessed through in vitro antioxidant experiments.RESULTS The results showed the optimum fermentation processes were 48 h of aerobic fermentation,36 h of anaerobic fermentation,ratio of 2∶3∶1 for Streptococcus thermophilus,Bifidobacterium bifidum and Lactobacillus acidophilus,solid-liquid ratio of 0.14 g·mL-1,inoculation quantity 5%,fermentation temperature 33℃.Under the optimal fermentation conditions,the content of neutral polysaccharide,acidic polysaccharide,and total flavonoid in Notoginseng Radix et Rhizoma residue increased by 105.64%,96.98%and 123.83%,respectively,which were high than those single-strain fermentation.The IC50 values of scavenging DPPH and ABTS free radicals in the fermentation products were 1.774 mg·mL-1 and 3.065 mg·mL-1,respectively,and the power of reducing Fe3+was 0.138 mmol FeSO4 g-1.The antioxidant capacity was significantly enhanced compared to the unfermented residues.CON-CLUSION The optimum fermentation process can significantly elevate the content of indicator components in Notoginseng Radix et Rhizoma residues and enhance its antioxidant capacity.Compared to single-strain fermentation,the content of various indicator compo-nents is significantly increased,showing no apparent antagonistic effect among the probiotics mentioned above.The study provides sci-entific evidence and data support for the resource utilization of Notoginseng Radix et Rhizoma residues.
