In recent years, clinical studies on targeted therapy and immunotherapy for advanced hepatocellular carcinoma used alone or in combination have provided abundant evidence on efficacy and safety for the selection of first-line therapies. However, no consensus has been reached on the selection of second-line therapies in various clinical guidelines for hepatocellular carcinoma, which is caused by the fact that existing evidence is limited to the options after failure of sorafenib and that there is still a lack of high-level evidence for new first-line therapies such as second-line therapies after resistance to targeted therapy and immunotherapy for hepatocellular carcinoma. This article reviews the results of current clinical trials and summarizes the studies on second-line therapies for hepatocellular carcinoma after resistance to first-line targeted therapy and immunotherapy for hepatocellular carcinoma based on the different mechanisms of action of drugs, as well as the research advances in recent years. For hepatocellular carcinoma patients with resistance to first-line targeted therapy and immunotherapy, targeted combination therapy and dual-immune therapy are expected to improve treatment outcome and survival, and more prospective clinical studies are needed in the future to provide effective and safe treatment regimens for hepatocellular carcinoma patients with resistance to targeted therapy and immunotherapy.

BACKGROUND:The proximal femoral nail antirotation is the preferred treatment for reverse osteoporotic intertrochanteric fractures.Bone cement enhancement can reduce the probability of proximal femoral nail antirotation cut-out and cut-through,but there are no relevant biomechanical studies demonstrating the effect of bone cement content and location on the stress and displacement of the fracture end. OBJECTIVE:To investigate the effects of different contents and locations of bone cement in cement-reinforced proximal femoral nail antirotation on stress,strain,and displacement of reverse osteoporotic femoral intertrochanteric fractures in the elderly by finite element analysis. METHODS:A healthy adult female right femur model was extracted by Mimics software and smoothed in Geometric software.Five types of internal fixation methods of proximal femoral nail antirotation(cementless,cephalic spherical 1 mL,cephalic spherical 2 mL,cephalic spherical 3.4 mL,and cylindrical 5 mL around spiral blade)and femoral intertrochanteric fracture(AO subtype 31-A3.1 type)model were established in Solidworks software.After assembly,the total stress distribution,peak stress and displacement of the five models of implants with the femur were compared in Ansys software. RESULTS AND CONCLUSION:(1)The peak stresses of proximal femoral nail antirotation with head-end spherical 1 mL,head-end spherical 2 mL,head-end spherical 3.4 mL,and cylindrical 5 mL enhanced proximal femoral nail antirotation around the spiral blade respectively were 571.07 MPa(located at the junction of the spiral blade and the main nail),495.45 MPa(located at the junction of the spiral blade and the main nail),467.20 MPa(located at the junction of the main nail and the distal screw connection),642.70 MPa(located at the junction of the main nail and distal screw connection),and 458.58 MPa(located at the junction of the spiral blade and the main nail).(2)The maximum displacements of proximal femoral nail antirotation with head end sphere 1 mL,head end sphere 2 mL,head end sphere 3.4 mL,and with cylindrical 5 mL enhancement around the spiral blade were 9.260 5,7.589 1,7.316 8,6.790 7,and 6.615 7 mm,respectively,all of which were located at the proximal end of the femoral head.(3)These findings revealed that for reverse femoral intertrochanteric fractures treated with proximal femoral nail antirotation,the bone cement enhancement had significant mechanical stability compared with no enhancement,and the enhancement of the spiral blade 5 mL around the perimeter was the best,which is more preferable for aged unstable intertrochanteric fractures.

Objective:To retrospectively analyze and summarize the clinical experience and therapeutic effect of anterograde Needle-perc combined with RIRS, namely N+ R (Needle perc + RIRS) technique in the treatment of complex calyceal diverticular stone.Methods:Retrospective analysis of 23 cases of complex renal caliceal diverticulum stones admitted to our hospital from January 2020 to December 2022. The complex factors mainly include the invisible cervical orifice of diverticulum, large stone volume, and special anatomical location, which makes single RIRS or PCNL treatment difficult or unsuccessful. There were 14 males and 9 females with an average age of (42.3±6.1) years. Three cases were upper calyceal diverticular stone, average size was (0.9±0.2)cm. Nine patients had diverticular stone in the middle posterior calyx, and the average size was (1.2±0.3)cm. The average size of four diverticular stone was (1.8±0.2)cm in the anterior middle calyx. Seven patients had diverticular stone with an average size of (1.3±0.1)cm in lower calyx. Among them, 12 patients underwent RIRS which were difficult or stone undiscovered, and 3 patients underwent PCNL and the operation was terminated due to failure of channel establishment. In our center, oblique supine lithotomy position (male) or prone split-leg position (female) was adopted, and the combined treatment of Needle-perc and RIRS was performed. Needle-perc puncture was completed under the guidance of full ultrasound. During the operation, methylene blue reagent or mutual guidance of two endoscopes was used to find the diverticulum neck and expand the outlet with holmium laser incision. Depending on the size and location of the stones, a single Needle-perc laser lithotripsy combined with stone removal in flexible ureteroscope was used, or dual lasers were be used simultaneously for stone removal under double endoscopes. The first stage stone free rate, operation time, hemoglobin decrease, complications, postoperative hospital stay and other conditions were analyzed.Results:All the 23 operations were completed successfully. The stone free rate within 48 hours and one month after surgery was 78.2% and 100.0% respectively. The average operation time was (61.5±12.2)min. The mean postoperative hospital stay was (2.8±0.6) days. The mean decrease of hemoglobin was (3.6±0.4)g/L. Three patients had fever and one patient had renal subcapsular effusion. After anti-inflammatory and symptomatic treatment, the patient was discharged. There was no incidence of Clavien-Dindo≥Ⅱcomplications such as blood transfusion, abdominal organ injury or urosepsis.Conclusions:Treatment of complex renal caliceal diverticulum stones using N+ R technique of anterograde needle-perc combined with RIRS can effectively improve the success rate of first-stage surgery. Overall, it is safe, efficient and feasible with the advantages of high stone free rate, lower damage, and few postoperative complications.

ObjectiveTo investigate the mechanism of Xumingtang in Gu Jin Lu Yan (《古今录验》) in regulating cell pyroptosis through the hypoxia-inducible factor-1α (HIF-1α)/NOD-like receptor pyrin domain-containing protein 3 (NLRP3) pathway in ischemic stroke (IS). MethodSD rats were randomly divided into a sham operation group, a model group, low- and high-dose Xumingtang groups, and a metformin group, with 20 rats in each group. Oral administration was performed for 3 days, and tissue samples were collected. Differential messenger RNA (mRNA) was screened using high-throughput sequencing, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed on key differentially expressed genes. The modified neurological severity score (mNSS) and 2,3,5-triphenyltetrazolium chloride (TTC) staining were used to evaluate the effect of brain infarction. Hematoxylin-eosin (HE) staining was used for pathological morphological observation of brain tissue. Enzyme-linked immunosorbent assay (ELISA) was used to compare the levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) in the ischemic cortical region. Double staining immunohistochemistry was used to detect the co-localization of HIF-1α and NLRP3. Real-time quantitative polymerase chain reaction (PCR) was performed to detect the mRNA expression of NLRP3, HIF-1α, Caspase-1 (CASP-1), and gasdermin D (GSDMD). Western blot was used to detect the protein expression of HIF-1α, NLRP3, CASP-1, and GSDMD. ResultA total of 5 705 differentially expressed genes (2 733 downregulated and 2 972 upregulated) were obtained by mRNA sequencing. After conversion to homologous genes and intersection with the pyroptosis gene set, 95 key differentially expressed pyroptosis genes were obtained. Compared with the sham operation group, the model group showed significantly increased mNSS scores, larger brain infarction areas (P<0.01), diverse neuronal morphology, disordered arrangement, widened cell gaps, significantly increased levels of IL-1β and IL-18 in the ischemic cortical region (P<0.01), enhanced co-localization fluorescence intensity, and significantly increased mRNA and protein expression levels of HIF-1α, NLRP3, CASP-1, and GSDMD (P<0.01). Compared with the model group, the high-dose Xumingtang group showed the most significant improvement in neurological function scores and brain infarction areas (P<0.01). The neuronal integrity and arrangement were more complete, and the cell gaps were narrower in all groups with drug treatment, with significantly reduced co-localization fluorescence intensity. Xumingtang could reduce the levels of IL-1β, IL-18, and the mRNA and protein expression of HIF-1α, NLRP3, CASP-1, and GSDMD (P<0.05, P<0.01), with the high-dose Xumingtang group showing the most significant effect (P<0.01). ConclusionXumingtang in Gu Jin Lu Yan can inhibit cell pyroptosis and promote neurological function recovery after IS, which may be related to the inhibition of the HIF-1α/NLRP3 pathway.
