This study compared the changes in chemical components during the processing of different types of Aconiti Lateralis Radix Praeparata(ALRP) in "Jianchang" faction, i.e., dried ginger-steamed ALRP pieces(Yin-FP), sand-fried ALRP pieces(Yang-FP), and rice swill water-bleached ALRP pieces(DFP), and provided a scientific basis for the mechanism in toxicity reduction and efficacy enhancement from a compositional perspective. Samples were collected during the processing of the three types of ALRP pieces, yielding raw ALRP pieces, water-bleached Yin-FP, ginger juice-moistened Yin-FP, steamed Yin-FP, water-bleached Yang-FP, sand-fried Yang-FP, water-bleached DFP, rice swill water-bleached DFP, and roasted DFP. Aconitine, mesaconitine, hypaconitine, benzoylaconine, benzoylmesaconine, benzoylhypaconine, aconine, mesaconine, hypaconine, salsolinol, fuziline, and higenamine in the extracts were determined by UPLC-MS/MS, and then content analysis and cluster heatmap analysis were performed on 11 sets of samples. During the processing of the three types of ALRP pieces, bleaching significantly reduced the content of 12 alkaloids; steaming, stir-frying, and roasting significantly reduced the content of diester-type alkaloids(aconitine, mesaconitine, and hypaconitine) and significantly increased the content of monoester-type alkaloids(benzoylaconine, benzoylmesaconine, and benzoylhypaconine) and aminoalcohol-type alkaloids(aconine, mesaconine, and hypaconine). During the processing of Yin-FP, the diester-type alkaloids continuously decreased, while the monoester-type and aminoalcohol-type alkaloids showed an initial decrease followed by an increase. During the processing of Yin-FP, Yang-FP, and DFP, the diester-type alkaloids continuously decreased, while the monoester-type and aminoalcohol-type alkaloids showed an initial decrease followed by an increase. Steamed Yin-FP showed a higher increase in content than fried Yang-FP and roasted DFP. Comprehensive analysis of content differences in toxic and therapeutic components in three ALRP pieces suggests that the distinctive processing methods in "Jianchang" faction can indeed achieve detoxification and efficacy enhancement on ALRP. This study provides references for understanding the mechanisms of action of the three processing methods.

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

Objective: To study the therapeutic effect of Huoxue Tongluo Decoction (HXTLD) on erectile dysfunction caused by ischemic stroke and identify the mechanisms involved. Methods: Network pharmacology was used to predict the key active ingredients and targets of HXTLD. Surgical methods were used to create a rat model of ischemic stroke. The rats were then given a suspension of HXTLD by ig administration. Erectile function was evaluated by Apomorphine (APO) induction. Real-time fluorescence quantitative reverse transcription-polymerase chain reaction (Real-time PCR) and Western blotting were used to detect the expression of related mRNAs and proteins in rat penile corpus cavernous tissue and brain tissue. Hematoxylin & Eosin (HE) staining was used to investigate structural changes in the penile cavernous tissue. Results: Network pharmacology showed that tumor necrosis factor (TNF), nitric oxide synthase 3 (eNOS), and vascular endothelial growth factor (VEGF) were the key targets of HXTLD in the treatment of erectile dysfunction caused by ischemic stroke. Experimental studies showed that HXTLD improved erectile dysfunction caused by ischemic stroke. HE results showed that HXTLD improved the structure of the corpus cavernosa. HXTLD also inhibited the expression of TNF and VEGF proteins in penile tissue (P < 0.05) and enhanced the expression of eNOS protein in penile tissue (P < 0.05). Conclusion: HXTLD improved the erectile function of rats with erectile dysfunction caused by ischemic stroke by regulating the mRNA and protein levels of TNF, eNOS and VEGF.

Objective To explore the efficacy and prognostic factors of cetuximab therapy for KRAS or all RAS wild-type(WT)metastatic colorectal cancer(mCRC).Methods We screened mCRC patients receiving at least two cycles of cetuximb and chemotherapy from those with KRAS WT(before November 2013)or all-RAS-WT(after November 2013)in the Department of Medical Oncology,Peking Union Medical College Hospital from November 2007 to December 2016. The relationship between the clinicopathological characteristics and the efficacy was retrospectively analyzed.Results A total of 60 patients were included. For the 34 patients receiving cetuximab as first-line treatment,the objective response rate(ORR)was 55.9%,and the progression-free survival and overall survival(OS)was 10 and 24 months,respectively. All-RAS-WT mCRC had significantly lower risk of progression than those with KRAS-only-WT(P=0.012),and left-sided colorectal cancer had higher ORR than right-sided colon cancer(62.1% vs. 0,P=0.033)during the first-line treatment. The median OS of the eight patients continuing cetuximab beyond first-line progression was 35.0(95%CI:23.6-46.4)months.Conclusions The efficacy of cetuximab for left-sided colorectal cancer was better than for right-sided colon cancer,and patients with all-RAS-WT have lower risk of progression than those with KRAS-only-WT. Patients benefiting from first-line cetuximab and continuing cetuximab beyond progression survive longer.

BACKGROUND: The immediate implantation in the anterior maxillary region is in a high risk of aesthetic complications. OBJECTIVE: To assess the prognosis of the labial bone plate after anterior maxillary repair with immediate implant combined with immediate restoration. METHODS: Thirty-two patients with single failed tooth in the anterior maxillary region were subjected to implantation of ZIMMER implants immediately after minimally invasive extraction. Good primary stability was achieved and immediate restoration was carried out. Final restoration was finished after 6-12 months of osteosynthesis and gingival shaping. The loading situation of the labial bone plate was recorded at 6 months post operation. RESULTS AND CONCLUSION: Final restoration was finished with normal loading in all the patients. No bleeding and swelling of the gingiva was recorded. The horizontal absorption of the labial bone plate at the upper margin, 5 mm and 10 mm below the upper margin was (-2.12±0.05), (-1.54±0.04), and (-1.01±0.06) mm, respectively. Therefore, absorption of the labial bone plate with varying degrees exists after anterior maxillary repair with immediate implant combined with immediate restoration.

Objective To study virulence factors and drug resistance mechanism of linezolid-intermediate Enterococcus faecalis(E.faecalis) isolated from patients with bloodstream infection.Methods Two linezolid-intermediate E.faecalis strains,namely A and B,were isolated from two patients with bloodstream infection,the treatment of two patients was analyzed.The minimum inhibitory concentration (MIC) of linezolid and vancomycin were determined.The virulence genes (esp,asa1,gelE,ace,agg,efaA,cylA,and hyl) and linezolid resistance genes (domain V region of the 23SrRNA,cfr,cfr[B],optrA) were amplified by polymerase chain reaction (PCR).PCR products of domain V region of 23SrRNA gene were sequenced and analyzed.Results Symptoms of two patients who isolated two linezolid-intermediate E.faecalis strains were controlled after accepted linezolid therapy.Strains A and B were both susceptible to vancomycin(MICs were 1μg/mL and 4μg/mL respectively),teicoplain,ampicillin,and nitrofurantoin,while intermediate to linezolid(MIC were both 4μg/mL).Two strains both contained multiple virulence factors,strain A were negative for cylA and hyl,strain B were negative for hyl and esp,but positive for other virulence genes.There was G2621T mutation in domain V region of 23SrRNA in strain A,and no variation was found in strain B.Drug resistance genes of cfr,cfr(B),and optrA were all negative in both strain A and B.Conclusion In the present study,two linezolid-intermediate E.faecalis strains isolated from patients with bloodstream infection were susceptible to vancomycin and ampicillin,although the treatment of linezolid in two patients is effective,the utilization of linezolid therapy in clinical practice still needs to be cautious.The mutation of target site is a significant resistance mechanism,it is necessary for us to pay more attention to these clinical strains which are non-susceptible to such antimicrobial agents,and the treatment strategy needs further study.

OBJECTIVETo identify the anatomical variability of the left spermatic vein (LSV) and determine its effect on the induction of experimental left varicocele (ELV) in adolescent rats.

METHODSWe equally randomized 30 adolescent male SD rats to groups A (LSV collaterals fully ligated and the left renal vein constricted), B (only the left renal vein constricted), and C (sham operation), observed the courses of the LSVs and measured their diameters. At 30 days after operation, we analyzed the changes in the left kidneys and the diameters of the LSVs.

RESULTSIrregular collaterals were observed in 90% of the LSVs and no abnormal changes were found in the left kidneys after surgery. The postoperative LSV diameter was remarkably increased in group A as compared with the baseline ([1.47 +/- 0.15 ] vs [0.16 +/- 0.08] mm, P < 0.01), but showed no significant difference in group B ([0.31 +/- 0.49] vs [0.15 +/- 0.07] mm, P > 0.05) and C ([0.17 +/- 0.07] vs [0.16 +/- 0.06] mm, P > 0.05), and it was significantly longer in A than in B (P < 0.01). The success rate of ELV induction was 100% in group A and 10% in group B, but no varicocele was observed in group C.

CONCLUSIONCorrect identification of the anatomical course of the LSV and ligation of its irregular collaterals are essential for the establishment of a stable and consistent ELV model.
