Objective:To explore the experience and learning curve of single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach.Methods:Clinical data of 138 patients undergoing single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via oral vestibular approach from Sep. 2019 to Dec. 2021 in the Department of Thyroid and Breast Surgery of Affiliated Hospital of North Sichuan Medical College were retrospectively analyzed. The cumulative sum (CUSUM) method and best-fit curve analysis were used to compare the differences in each index such as operative time, intraoperative bleeding, number of lymph nodes cleared in the central region and postoperative related complications at various stages of the learning curve.Results:All 138 patients underwent single-line suspension rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach, and one patient was converted to open surgery due to large intraoperative bleeding in the mass. There were 14 males and 124 females, mean age (36.07±8.49) years (20-55 years), thyroid tumor size (7.74±6.49) mm (2.4-50mm), 5 cases underwent Subtotal thyroidectomy, 129 cases underwent Unilateral lobectomy + lymph node dissection in the middle region, and 4 cases total thyroidectomy + central zone lymph node dissection. The number of surgical cases corresponding to the apex of the CUSUM learning curve was 45, and the learning curve was divided into two stages: the learning improvement stage (1-45 cases) and the mastery stage (46-138 cases). The operative time, intraoperative bleeding, postoperative hospital stay, and chin numbness were all lower in the proficiency period than in the learning and training period ( P<0.05), and the number of lymph nodes cleared in the central region was larger than that in the learning and improvement stage ( P<0.05), while the differences in other indexes between the two stages were not statistically significant ( P>0.05) . Conclusion:The single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach has clinical application value and is worth promoting, and the number of surgical cases to be accumulated to master this technique is 45.

Background::Limited information exists regarding the impact of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection on psoriasis patients. The objective of this study was to identify clinical factors associated with the prognosis of psoriasis following SARS-CoV-2 infection.Methods::A retrospective, multicenter study was conducted between March and May 2023. Univariable and multivariable logistic regression analyses were employed to identify factors associated with coronavirus disease 2019 (COVID-19)-related psoriasis outcomes. The study included 2371 psoriasis patients from 12 clinical centers, with 2049 of them having been infected with SARS-CoV-2.Results::Among the infected groups, lower exacerbation rates were observed in individuals treated with biologics compared to those receiving traditional systemic or nonsystemic treatments (22.3% [236/1058] vs. 39.8% [92/231] vs. 37.5% [140/373], P <0.001). Psoriasis progression with lesions (adjusted odds ratio [OR] = 8.197, 95% confidence interval [95% CI] = 5.685–11.820, compared to no lesions), hypertension (adjusted OR = 1.582, 95% CI = 1.068–2.343), traditional systemic (adjusted OR = 1.887, 95% CI= 1.263–2.818), and nonsystemic treatment (adjusted OR= 1.602, 95% CI= 1.117–2.297) were found to be associated with exacerbation of psoriasis after SARS-CoV-2 infection, but not biologics (adjusted OR = 0.931, 95% CI = 0.680–1.274, compared to no treatment), according to multivariable logistic regression analysis. Conclusions::A reduced risk of psoriasis exacerbation after SARS-CoV-2 infection was observed with biologics compared to traditional systemic and nonsystemic treatments. Significant risk factors for exacerbation after infection were identified as existing psoriatic lesions and hypertension.

Objective Previous studies on the association between lipid profiles and chronic kidney disease(CKD)have yielded inconsistent results and no defined thresholds for blood lipids. Methods A prospective cohort study including 32,351 subjects who completed baseline and follow-up surveys over 5 years was conducted.Restricted cubic splines and Cox models were used to examine the association between the lipid profiles and CKD.A regression discontinuity design was used to determine the cutoff value of lipid profiles that was significantly associated with increased the risk of CKD. Results Over a median follow-up time of 2.2(0.5,4.2)years,648(2.00%)subjects developed CKD.The lipid profiles that were significantly and linearly related to CKD included total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),TC/HDL-C,and TG/HDL-C,whereas low-density lipoprotein cholesterol(LDL-C)and LDL-C/HDL-C were nonlinearly correlated with CKD.TC,TG,TC/HDL-C,and TG/HDL-C showed an upward jump at the cutoff value,increasing the risk of CKD by 0.90%,1.50%,2.30%,and 1.60%,respectively,whereas HDL-C showed a downward jump at the cutoff value,reducing this risk by 1.0%.Female and participants with dyslipidemia had a higher risk of CKD,while the cutoff values for the different characteristics of the population were different. Conclusion There was a significant association between lipid profiles and CKD in a prospective cohort from Northwest China,while TG,TC/HDL-C,and TG/HDL-C showed a stronger risk association.The specific cutoff values of lipid profiles may provide a clinical reference for screening or diagnosing CKD risk.

Non-neonatal tetanus is an acute, specific, toxic disease in patients over 28 days of age, characterized by continuous rigidity and paroxysmal spasms of the skeletal muscles throughout the body caused by the intrusion of Clostridium tetani through skin or mucosal membrane into the body and reproducing in anaerobic environments to produce exotoxins. The mortality rate of severe patients is close to 100% without medical intervention. Even with aggressive comprehensive treatment, the global mortality rate remains at 30%-50%, making it a potentially fatal disease. In order to standardize the diagnosis, treatment and prevention of non-neonatal tetanus, based on "Regulation for Diagnosis and Treatment of Non-neonatal Tetanus (2019 Edition)", experts have revised this regulation according to clinical practice and recent research progress in this field to guide medical institutions in the prevention and control of non-neonatal tetanus. This article interprets the key points and basis for updating the 2024 edition regulation to guide clinical implementation and application.

OBJECTIVE To explore the molecular mechanism of Compound Dihuang Granule in treating Parkinson's disease(PD)with yin-deficiency and dynamic wind syndrome by regulating the changes of ubiquitin-proteasome system-related proteins.METHODS SPF male SD rats were randomly selected as normal control group and sham operation group,13 rats in each group.The remaining rats were treated with 6-hydroxydopamine lateral brain injection to damage the substantia nigra to establish PD yin-deficien-cy and dynamic wind syndrome rat model.The established rats were randomly divided into model group,madopar group(150 mg·kg-1),low,medium and high dose groups of Compound Dihuang Granule(1.75,3.5,7 g·kg-1),13 rats in each group.Each group was given drugs by intragastric gavage for 28 d.The general conditions and neurobehavioral manifestations of the rats were observed;the expression of ubiquitin(UB),ubiquitin activating enzyme(UBE1),ubiquitin conjugating enzyme(UBE2A)and ubiquitin carboxyl terminal hydrolase(UCH-L1)positive cells,protein and mRNA expression levels in the damaged lateral stria-tum of the brain of rats were detected by immunohistochemistry,Western blot and qPCR methods;changes of dopamine(DA)content in the damaged lateral striatum of the brain of rats were detected by ELISA.RESULTS There was no significant difference in general conditions between the normal control group and the sham operation group,and there was no significant difference in the number of ro-tations,suspension time and number of moving grids.Compared to the sham-op group,the model group rats showed poor spirit,irrita-bility,limb tremor,slow movement,dark yellow fur,less food intake,reduced body weight;the modeling increased number of rota-tions,decreased hanging time and number of moving grids(P<0.01),significantly decreased expression of UB,UBE1,UBE2A,and UCH-L1 positive cells,mRNA and protein expression levels in the damaged lateral striatum(P<0.01),and significantly decreased DA content(P<0.01).Compared with the model group,the general condition of the rats in the madopar group and Compound Di-huang Granule groups was improved,the number of rotations was reduced,the hanging time and number of moving grids were increased(P<0.05,P<0.01),the expression of UB,UBE1,UBE2A,and UCH-L1 positive cells,mRNA and protein expression levels were increased(P<0.05,P<0.01),and the DA content was increased(P<0.01);behavioral tests and the expression levels of various in-dicators were most significantly improved in the madopar group and the high-dose Compound Dihuang Granule group(P<0.05,P<0.01),and there was no statistical significance between the two groups.CONCLUSION Compound Dihuang Granule may play a role in treating PD yin-deficiency and dynamic wind syndrome by regulating the expression of ubiquitin-proteasome system-related proteins,reducing abnormal protein aggregation,and thus alleviating DA content deficiency,and the high-dose Compound Dihuang Granule has the best effect.
