Temporomandibular disorders (TMD) is a common oral disease characterized by complex etiology, diverse symptomatology and varied treatment approaches. When managing TMD patients, dentists should adopt a generalist mindset, grasp the core connotation of "patient-centeredness", guided by the biopsychosocial model, and make a comprehensive judgment from a multi-dimensional, multi-systemic, and multi-factorial perspective to reach a reasonable etiological analysis and an accurate diagnosis, in order to realize the personalized and holistic treatment of TMD under the guidance of general practice thinking and multi-disciplinary collaboration.

Objective:To compare the short-term clinical outcomes of thoracoscopy-assisted minimally invasive mitral valve surgery(minimally invasive cardiac surgery MICS group)versus conven-tional median sternotomy mitral valve surgery(conventional surgery group),including surgical metrics,postoperative complications,transfusion volume,and in-hospital mortality rate.Methods:A ret-rospective analysis was performed for 141 patients who underwent mitral valve surgery in Chongqing General Hospital from January 2021 to June 2022,and these patients were divided into MICS group with 42 patients and conventional surgery group with 99 patients.Propensity score matching at a ratio of 1∶1 was performed to ob-tain 82 patients,with 41 patients in each group,and related data were collected and compared,including surgical procedure,cardiopul-monary bypass time,postoperative ventilation time,transfusion volume,and in-hospital mortality.Results:There were no significant differences between the MICS group and the conventional surgery group in sex,age,cardiac functional grading,and comorbidity with diabetes or hypertension,and as for the surgical procedure,there was no significant difference between the two groups in the number of patients undergoing atrial fibrillation radiofrequency ablation(11/42 vs.26/99,P=0.583)or tricuspid valvuloplasty(14/42 vs.39/99,P=0.310).Compared with the conventional surgery group,the MICS group had significantly longer aortic cross-clamp time[(122±48)min vs.(91±50)min,P=0.031]and cardiopulmonary bypass time[(180±73)min vs.(136±72)min,P=0.033],while there was no significant difference in postoperative ventilation time between the two groups after surgery[18.6(12.0,36.2)h vs.24.0(15.5,33.1)h,P=0.265].There was no significant difference in the number of patients with acute renal failure after surgery between the MICS group and the conventional surgery group[grade 1:3(42)vs.7(99);grade 2:0(42)vs.2(99);grade 3:1(42)vs.9(99);P=0.398].There was also no significant difference in the number of patients receiving hemodialysis after surgery between the two groups[1(42)vs.4(99),P=0.531].The MICS group had a significantly lower postoperative transfusion volume than the conventional surgery group[120(80,240)mL vs.400(200,600)mL,P=0.002],and there was no significant difference in in-hospital mortality rate between the two groups[1(42)vs.2(99),P=0.665].After propensity score matching,there were no significant differences between the two groups in general characteristics(sex,age,and comorbidities).Compared with the conventional surgery group,the MICS group had longer cardiopulmonary bypass time[(165±73)min vs.(122±74)min,P=0.053]and aortic cross-clamp time[(119±48)min vs.(98±52)min,P=0.073]and a significantly lower postoperative transfusion volume[120(80,240)mL vs.400(200,600)mL,P<0.001].There were no significant differences between the two groups in 30-day in-hospital mortality rate and postoperative compli-cations(including acute renal failure and requirement for hemodialysis).Conclusion:Thoracoscopy-assisted minimally invasive mitral valve surgery has comparable short-term clinical outcomes and safety to conventional sternotomy.Although MICS requires longer cardiopulmonary bypass time and aortic cross-clamp time,it has relatively low requirements for postoperative transfusion and shows favorable clinical outcomes.

Background Pneumoconiosis is a chronic inflammatory disease that cannot be completely cured. Therefore, how to control lung inflammation and delay of the body aging is one of the keys to treating pneumoconiosis. The studies in past two decades suggested that many small molecule drugs are able to enhance cardiopulmonary function. Objective To explore the effects of homeopathic dosing and combined dosing of β-nicotinamide mononucleotide and taurine on experimental silicosis in rats. Methods Seventy-two SD specific pathogen-free rats were randomized into 4 groups (18 mice in each group): negative control group (ultrapure water, without dust), positive control group, homeopathic treatment group, co-administered treatment group. One mL of quartz dust suspension was injected into the rat trachea by disposable non-exposed tracheal injection method (50 mg·mL⁻¹) to establish a rat silicosis model. Rats were administered by gavage since the 4th day after dust exposure. The homeopathic treatment group rats received taurine solution (0.03 g·mL⁻¹) in the morning and β-nicotinamide mononucleotide (0.03 g·mL⁻¹) in the afternoon; the co-administered treatment group rats received a mixed solution (0.015 g·mL⁻¹ β-nicotinamide mononucleotide + 0.015 g·mL⁻¹ taurine) twice, in the morning and afternoon respectively. The positive and negative control groups received equivalent of ultrapure water in the morning and afternoon. All groups of rats were administered 5 d a week for a total of 6 weeks. The rats were neutralized after 6 weeks of administration. Organ coefficient, lung hydroxyproline content, whole lung dry and wet weights, whole lung free silica content, and cell count and classification in lung lavage fluid were measured and calculated, and lung histopathological changes in lung samples were observed. Results Compared with the positive control group, the whole lung wet weight, whole lung dry weight , total cell count, neutrophil rate, lung organ coefficient, lung hydroxyproline content, and whole lung free silica content were reduce in the homeopathic treatment group, and the co-administered treatment group (P＜0.05). Compared with the negative control group, the total cell count, neutrophil rate, lung organ coefficient, lung hydroxyproline content, and whole lung free silica content were elevated in the homeopathic treatment group and the co-administered treatment group, the whole lung dry weight was elevated in the co-administered treatment group, and those differences were all statistically significant (P＜0.05). The rat lung histopathological results showed that, in the positive control group, round or oval nodules were formed in the lung tissue, which were phagocytic cellular nodules, and the alveolar structures in some areas still existed. The histopathological changes in the homeopathic treatment group and the co-administered treatment group were similar to those of the positive group, but less severe. No pathological change was observed in the lung tissue of the negative control group. Conclusion Some improvement and dust removal in experimental silicosis rats by homeopathic dosing and combined dosing of β-nicotinamide mononucleotide and taurine are observed.

Objective:To explore the effects of different combination of Er∶YAG laser irradiation parameters on the dentinal tu-bule sealing.Methods:160 dentin discs with 2 mm thickness were etched with 0.5 mmol/L EDTA to establish the dentine hyper-sensitivity models.The discs were randomly divided into 16 groups(n=10).The R02 and R14 handpieces were used to deliver Er∶YAG laser to the dentin discs according to the different output power(W),irradiation distance(cm)and irradiation time(s/cm2).Then,the samples of each group were divided into immediate irradiation subgroup and acid etching and wear subgroup(n=5).The dentinal tubules were observed with SEM,and the exposed area,the sealed rate and the occlusion depth of dentinal tubules were e-valuated with ImageE-Pro Plus 6.0 software.Results:The dentinal tubules in the control group opened uniformly with clear perime-ter,they were enlarged and opened after acid etching and tooth brushing.The dentinal tubules shrinked or sealed well with the melt layer after treatment by Er∶YAG laser irradiation with either parameter combination.Especially,uniform and seamless melt layer as well as similar dentin surface morphology before and post the acid etching and tooth brushing were obtained when the dentin discs were exposed to the following Er∶YAG laser irradiation parameter combinations,i.e.(R02,0.5 W,3 cm,20 s/cm2),(R14,0.5 W,3 cm,20 s/cm2)and(R14,0.6 W,3 cm,20 s/cm2).Significantly decreased exposed area and increased seal rate in the dentinal tubules treated in the above 3 laser irradiation parameter combina-tion groups were observed than those in the other groups(P＜0.05).Morphological analysis confirmed that whether the acid etching and tooth brushing were exerted.The occlusion depth of dentin tubule was more than 2.0 μm in the dentinal tubules treated in the above 3 groups.Conclusion:Er∶YAG laser irradiation parameter combinations of R02,0.5 W,3 cm,20 s/cm2,R14,0.5 W,3 cm,20 s/cm2 and R14,0.6 W,3 cm,20 s/cm2 are suitable for the best dentin tubule sealing.
