Purpose::This study evaluated the methods and clinical effects of multidisciplinary collaborative treatment for occlusal reconstruction in patients with old jaw fractures and dentition defects.Methods::Patients with old jaw fractures and dentition defects who underwent occlusal reconstruction at the Third Affiliated Hospital of Air Force Military Medical University from January 2018 to December 2022 were enrolled. Clinical treatment was classified into 3 phases. In phase I, techniques such as orthognathic surgery, microsurgery, and distraction osteogenesis were employed to reconstruct the correct 3-dimensional (3D) jaw position relationship. In phase II, bone augmentation and soft tissue management techniques were utilized to address insufficient alveolar bone mass and poor gingival soft tissue conditions. In phase III, implant-supported overdentures or fixed dentures were used for occlusal reconstruction. A summary of treatment methods, clinical efficacy evaluation, comparative analysis of imageological examinations, and satisfaction questionnaire survey were utilized to evaluate the therapeutic efficacy in patients with traumatic old jaw fractures and dentition defects. All data are summarized using the arithmetic mean ± standard deviation and compared using independent sample t-tests. Results::In 15 patients with old jaw fractures and dentition defects (an average age of 32 years, ranging from 18 to 53 years), there were 7 cases of malocclusion of single maxillary fracture, 6 of malocclusion of single mandible fracture, and 2 of malocclusion of both maxillary and mandible fractures. There were 5 patients with single maxillary dentition defects, 2 with single mandibular dentition defects, and 8 with both maxillary and mandibular dentition defects. To reconstruct the correct 3D jaw positional relationship, 5 patients underwent Le Fort I osteotomy of the maxilla, 3 underwent bilateral sagittal split ramus osteotomy of the mandible, 4 underwent open reduction and internal fixation for old jaw fractures, 3 underwent temporomandibular joint surgery, and 4 underwent distraction osteogenesis. All patients underwent jawbone augmentation, of whom 4 patients underwent a free composite vascularized bone flap (26.66%) and the remaining patients underwent local alveolar bone augmentation. Free gingival graft and connective tissue graft were the main methods for soft tissue augmentation (73.33%). The 15 patients received 81 implants, of whom 11 patients received implant-supported fixed dentures and 4 received implant-supported removable dentures. The survival rate of all implants was 93.82%. The final imageological examination of 15 patients confirmed that the malocclusion was corrected, and the clinical treatment ultimately achieved occlusal function reconstruction. The patient satisfaction questionnaire survey showed that they were satisfied with the efficacy, phonetics, aesthetics, and comfort after treatment.Conclusion::Occlusal reconstruction of old jaw fractures and dentition defects requires a phased sequential comprehensive treatment, consisting of 3D spatial jaw correction, alveolar bone augmentation and soft tissue augmentation, and implant-supported occlusal reconstruction, achieving satisfactory clinical therapeutic efficacy.

The paper explores the evolution of "bone-approaching" acupuncture, its effect target and mechanism. The concrete operation procedure of "bone-approaching" method is recorded originally in Huangdi Neijing (Inner Canon of Yellow Emperor) as short needling and Shu needling (referring to the category of the five needling technique). The periosteum is the most effective stimulation target of "bone-approaching" acupuncture for analgesia, regaining consciousness and regulating spirit. The "bone-approaching" acupuncture is not only prominently effective on bone bi syndrome, but also has the unique effect on painful, encephalogenic and emotional diseases. The paper summarizes and improves "bone-approaching" acupuncture, i.e. "touching bone surface" with needle tip by slow insertion, "touching bone surface" without pain by swift insertion and "touching bone" with needle body by oblique insertion. It contributes to the inheritance, development and supplementation to the bone needling techniques in Huangdi Neijing and is significant for broadening the clinical application range of acupuncture.

A resurging interest in targeted covalent inhibitors (TCIs) focus on compounds capable of irreversibly reacting with nucleophilic amino acids in a druggable target. p97 is an emerging protein target for cancer therapy, viral infections and neurodegenerative diseases. Extensive efforts were devoted to the development of p97 inhibitors. The most promising inhibitor of p97 was in phase 1 clinical trials, but failed due to the off-target-induced toxicity, suggesting the selective inhibitors of p97 are highly needed. We report herein a new type of TCIs (i.e., FL-18) that showed proteome-wide selectivity towards p97. Equipped with a Michael acceptor and a basic imidazole, FL-18 showed potent inhibition towards U87MG tumor cells, and in proteome-wide profiling, selectively modified endogenous p97 as confirmed by in situ fluorescence scanning, label-free quantitative proteomics and functional validations. FL-18 selectively modified cysteine residues located within the D2 ATP site of p97. This covalent labeling of cysteine residue in p97 was verified by LC‒MS/MS-based site-mapping and site-directed mutagenesis. Further structure-activity relationship (SAR) studies with FL-18 analogs were established. Collectively, FL-18 is the first known small-molecule TCI capable of covalent engagement of p97 with proteome-wide selectivity, thus providing a promising scaffold for cancer therapy.

Background/Aims:
Depression and anxiety are associated with poorer outcomes in patients with hepatocellular carcinoma (HCC). However, the prevalence of depression and anxiety in HCC are unclear. We aimed to establish the prevalence of depression and anxiety in patients with HCC.
Methods:
MEDLINE and Embase were searched and original articles reporting prevalence of anxiety or depression in patients with HCC were included. A generalized linear mixed model with Clopper-Pearson intervals was used to obtain the pooled prevalence of depression and anxiety in patients with HCC. Risk factors were analyzed via a fractional-logistic regression model.
Results:
Seventeen articles involving 64,247 patients with HCC were included. The pooled prevalence of depression and anxiety in patients with HCC was 24.04% (95% confidence interval [CI], 13.99–38.11%) and 22.20% (95% CI, 10.07–42.09%) respectively. Subgroup analysis determined that the prevalence of depression was lowest in studies where depression was diagnosed via clinician-administered scales (16.07%;95% CI, 4.42–44.20%) and highest in self-reported scales (30.03%; 95% CI, 17.19–47.01%). Depression in patients with HCC was lowest in the Americas (16.44%; 95% CI, 6.37–36.27%) and highest in South-East Asia (66.67%; 95% CI, 56.68–75.35%). Alcohol consumption, cirrhosis, and college education significantly increased risk of depression in patients with HCC.
Conclusions
One in four patients with HCC have depression, while one in five have anxiety. Further studies are required to validate these findings, as seen from the wide CIs in certain subgroup analyses. Screening strategies for depression and anxiety should also be developed for patients with HCC.

Panax ginseng and Panax quinquefolius have similar bioactive components and morphological characteristics, but they are known to have different medicinal values, high-sensitive and accurate method is expected to identify the sources of ginseng products and evaluate the quality, but with a huge challenge. Our established UHPLC-TOF/MS method coupled with orthogonal partial least squares discriminant analysis (OPLS-DA) model based on 18 ginsenosides was applied to discriminate the sources of raw medicinal materials in ginseng products, and nested PCR strategy was used to discover 6 novel single nucleotide polymorphism (SNP) sites in functional dammarenediol synthase (DS) gene for genetic authentication of P. ginseng and P. quinquefolius for the first time. OPLS-DA model could identify the sources of raw ginseng materials are real or not. SNP markers were applied to identify ginseng fresh samples as well as commercial products, and proved to be successful. This established molecular method can tell exact source information of adulterants, and it was highly sensitive and specific even when total DNA amount was only 0.1 ng and the adulteration was as low as 1%. Therefore, this study made an attempt at the exploration of new type SNP marker for variety authentication and function regulation at the same time, and the combination of chemical and molecular discrimination methods provided the comprehensive evaluation and authentication for the sources of ginseng herbs and products.

Objective:
To observe the dynamic impacts of shock waves on the severity of lung injury in rats with different injury distances.
Methods:
Simulate open-field shock waves; detect the biomechanical effects of explosion sources at distances of 40, 44, and 48 cm from rats; and examine the changes in the gross anatomy of the lungs, lung wet/dry weight ratio, hemoglobin concentration, blood gas analysis, and pathology.
Results:
Biomechanical parameters such as the overpressure peak and impulse were gradually attenuated with an increase in the injury distance. The lung tissue hemorrhage, edema, oxygenation index, and pathology changed more significantly for the 40 cm group than for the 44 and 48 cm groups. The overpressure peak and impulse were significantly higher for the 40 cm group than for the 44 and 48 cm groups ( < 0.05 or < 0.01). The animal mortality was significantly higher for the 40 cm group than for the other two groups (41.2% . 17.8% and 10.0%, < 0.05). The healing time of injured lung tissues for the 40 cm group was longer than those for the 44 and 48 cm groups.
Conclusions
The effects of simulated open-field shock waves on the severity of lung injuries in rats were correlated with the injury distances, the peak overpressure, and the overpressure impulse.

【Objective】To explore the effects of overexpressed senescence marker protein 30 (SMP30) on cell proliferation and antioxidative activity in human lens epithelial cell(HLEC)line SRA01/04 under high-calcium mediated oxidative stress. 【Methods】There were 3 groups in this experiment:SMP30 overexpressed group (OE,experimental group),NCOE group (negative control group) and SRA01/04 group (blank control group). OE and NCOE lentiviral vectors were used to transfect SRA01/04 respectively. A high- calcium- mediated- stress cell model was established by culturing cells with medium containing 15 mmol/L CaCl2 for 24 h. BrdU assay was used to measure cell proliferation. SOD assay kit and GSSG/T- GSH assay kit were used to detect the level of intracellular oxidative stress. 【Results】Green fluorescence protein could be observed in all transfected cell groups under fluorescence microscope and the transfection efficiency was close to 80% ,suggesting that OE cell model was constructed successfully. Under the high calcium culture conditions,the activity of relative cell proliferation and SOD in OE group[(3.89 ± 0.20)and(47.5 ± 4.3 U/mg)]were significantly higher than that in NCOE group[(2.82 ± 0.34)and(30.6 ± 4.2 U/mg)]and SRA01/04 group[(2.96 ± 0.25)and(26.8 ± 1.5 U/mg)],the ratio of GSSG/T-GSH in OE group(2.36 ± 0.51)was significantly lower than that in NCOE group(16.36 ± 2.48)and SRA01/04 group(20.12 ± 2.54)(n=3,P<0.05);there was no significant difference between NCOE group and SRA01/04 group (n=3,P>0.05). 【Conclusions】Overexpression of SMP30 increased the activity of cell proliferation and SOD,but decreased the ratio of GSSG/T- GSH in SRA01/04 cell(HLEC),indicating that SMP30 may alleviate the progression of high-calcium-mediated oxidative cell damage and possess the cytoprotective functions in HLEC.

Objective Mini-invasive Carisolv is an aid to treat dental caries for patients with dental phobia. The article was to investigate the level of pain in caries removal using mini-invasive Carisolv III gel and mechanical methods with four psychological indicators. Methods We collected 120 primary molar tooth caries of 60 children treated in our hospital. Two primary molar tooth caries of each child were respectively treated with Carisolv III gel (Group A) and mechanical method (Group B) for caries removal. Psychological indicators including the visual analog scale (VAS), the Frank1 behavior rating scale (Frank1), the Kuttner law (Kuttner), and the Houpt behavior rating scale (Houpt) were used to assess the level of pain, degree of cooperation, pain tolerance and comfort. The clinical efficiency after six months and treatment time were compared between the two groups. Results There was no statistically significant difference before treatment between the two groups using the four psychological indicators (P>0.05) , while significant differences were found during and after the treatment between the two groups (P<0.05). Then, Carisolv III gel and mechanical groups for careis removal were compared before, during and after treatment themselves. In the Carisolv III gel group, there was no statistically significant difference using the four psychological indicators (P>0.05). In the mechanical group, there were statistically significant differences before and during treatment or before and after treatment using the four psychological indicators (P<0.05). The treatment time in Carisolv III gel group was longer than in mechanical group (P=0.001). There was no statistical difference between the two groups in filling examination after six months (P=0.082). Conclusion Carisolv III gel for caries removal can effectively avoid pain, improve comfort and decrease fear in children, which can be promoted in clinical application.
