Traditional open head and neck surgery often leaves permanent scars,significantly affecting appearance.The emergence of surgical robots has introduced a new era for minimally invasive surgery.However,the complex anatomy of the head and neck region,particularly the oral and maxillofacial areas,combined with the high costs associated with established systems such as the da Vinci,has limited the widespread adoption of surgical robots in this field.Recently,surgical robotic platform in China has developed rapidly,exemplified by the promise shown by the KangDuo Surgical Robot(KD-SR).Although the KD-SR has achieved some results comparable to the da Vinci surgical robot in urology and colorectal surgery,its performance in complex head and neck regions remains untested.This study evaluated the feasibility,effectiveness,and safety of the newly developed KD-SR-01,comparing it with standard endoscopic systems in head and neck procedures on porcine models.We performed parotidectomy,submandibular gland resection,and neck dissection,collected baseline characteristics,perioperative data,and specifically assessed cognitive workload using the NASA-TLX.None of the robotic procedures were converted to endoscopic or open surgery.The results showed no significant difference in operation time between the two groups(P=0.126),better intraoperative bleeding control(P=0.001),and a significant reduction in cognitive workload(P<0.001)in the robotic group.In conclusion,the KD-SR-01 is feasible,effective,and safe for head and neck surgery.Further investigation through well-designed clinical trials with long-term follow-up is necessary to establish the full potential of this emerging robotic platform.

Chang-Kang-Fang (CKF) formula, a Traditional Chinese Medicine (TCM) prescription, has been widely used for the treatment of irritable bowel syndrome (IBS). However, its potential material basis and underlying mechanism remain elusive. Therefore, this study employed an integrated approach that combined ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q/TOF-MS) with network pharmacology to systematically characterize the phytochemical components and metabolites of CKF, as well as elucidating its underlying mechanism. Through this comprehensive analysis, a total of 150 components were identified or tentatively characterized within the CKF formula. Notably, six N-acetyldopamine oligomers from CicadaePeriostracum and eight resin glycosides from Cuscutae Semen were characterized in this formula for the first time. Meanwhile, 149 xenobiotics (58 prototypes and 91 metabolites) were detected in plasma, urine, feces, brain, and intestinal contents, and the in vivo metabolic pathways of resin glycosides were elaborated for the first time. Furthermore, network pharmacology and molecular docking analyses revealed that alkaloids, flavonoids, chromones, monoterpenes, N-acetyldopamine dimers, p-hydroxycinnamic acid, and Cus-3/isomer might be responsible for the beneficial effects of CKF in treating IBS, and CASP8, MARK14, PIK3C, PIK3R1, TLR4, and TNF may be its potential targets. These discoveries offer a comprehensive understanding of the potential material basis and clarify the underlying mechanism of the CKF formula in treating IBS, facilitating the broader application of CKF in the field of medicine.

Objective:To explore the clinical efficacy and safety of the camrelizumab combined with apatinib and chemotherapy as second-line or later therapy in human epidermal growth factor receptor-2 (HER-2) negative advanced gastric cancer.Methods:A total of 66 patients with HER-2 negative advanced gastric cancer and first-line treatment failure in Shandong Cancer Hospital Affiliated to Shandong First Medical University from March 2018 to September 2021 were selected. They were divided into study group ( n=22) and control group ( n=44) according to the different treatment regimens. The patients in the study group were treated with camrelizumab combined with apatinib and chemotherapy, and the patients in the control group were treated with chemotherapy alone. The short-term efficacy, progression-free survival (PFS) , overall survival (OS) and the occurrence of adverse reactions were compared, and Cox regression analysis was used to analyze the influencing factors of prognosis. Results:After at least 2-4 cycles of treatment, the ORR in the study group and the control group were 9.1% (2/22) and 0 (0/44) respectively, with no statistically significant difference ( P=0.108) . DCR in the two groups were 77.3% (17/22) and 45.5% (20/44) respectively, with a statistically significant difference ( χ2=6.03, P=0.014) . The study group didn’t reach median OS and the median OS in the control group was 11.7 months, with no statistically significant difference ( χ2=1.59, P=0.207) . The study group didn’t reach median PFS and the median PFS in the control group was 3.2 months, with a statistically significant difference ( χ2=10.13, P=0.001) . Multivariate Cox regression analysis showed that treatment method was an independent influencing factor for PFS in patients with HER-2 negative advanced gastric cancer ( HR=0.33, 95% CI: 0.15-0.75, P=0.008) . In terms of adverse reactions, there was a statistically significant difference in the incidence of elevated alanine aminotransferase between the study group and the control group [31.8% (7/22) vs. 6.8% (3/44) , χ2=5.32, P=0.021]. There were no adverse-related deaths in both groups. Conclusion:Compared with chemotherapy alone, camrelizumab combined with apatinib and chemotherapy as a second-line or later therapy in HER-2 negative advanced gastric cancer can prolong PFS and improve DCR, but the incidence of elevated alanine aminotransferase increases significantly.

Objective:To explore the effect of adipose derived mesenchymal stem cells to regulate the differentiation of macrophage RAW264.7.Methods:First,we used RAW264.7 cells to simulate macrophage and induced them to M 1 macrophage with lipopolysaccharide ( LPS,1 μg/ml) .Then we cultured these RAW264.7 cells in culture mediums which were previously used to culture adipose derived mesenchymal stem cells to imitate the transplantation of ADMSC .Last,the mRNA relative expression of IL-10, IGF-1,Arg-1,TNF-α,FIZZ1,SPHK-1 was detected by real-time PCR.The protein expression of IL-12 p40,IL-27 Rα,IL-10 was detected by Western blot.Results:After been cultured in ADMSCCM and induced by LPS ,M1 markers (TNF-αmRNA,IL-12 p40;P<0.05) of the RAW264.7 cells declined while M2 markers (IGF-1 mRNA,IL-10 mRNA,IL-10;P<0.05) rose.Conclusion: ADMSC can secrete soluble cytokines to induce the RAW264.7 cell,which have been induced to the M1 macrophages,to differentiate towards M2 macrophages.

Objective:To evaluate the effectiveness of Minqing Ao dental desensitizer in the treatment of early childhood caries (ECC).Methods:41 0 teeth with ECC in 1 1 0 cases were divided into 3 groups.Minqing Ao dental desensitizer,fluoride toothpaste and ordinary toothpaste without fluoride were respectively used in group A,B and C.The laser fluorescence value(LFV)was meas-ured and compared before treatment,2,4,6 weeks and 6 months after treatment.Results:2 weeks after treatment,the LFV was not significantly changed in the 3 groups.4 weeks after treatment LFV in group A was decreased(P<0.01 ),the LFV in group A was lower than that in group B(P<0.05)and in group C(P<0.01 ).While there was no significant difference between group B and C(P>0.05).6 weeks after treatment LFV in group A and B was decreased(P<0.01 and P<0.05),there was significant difference be-tween each 2 groups(P<0.05).6 weeks and 6 months after treatment LFV in group A was lower than that in group B(P<0.01 ),and in group B was lower than that in group C(P<0.01 ).Conclusion:Minqing Ao is effective for treatment of early childhood caries.
