Objective To explore the feasibility of endoscopic thyroidectomy through the approach of areola of breasts.Methods Endoscopic thyroidectomy via areola of breasts approach was carried out in 26 cases from March 2003 to September 2005.Thyroid nodules were right-sided in 13 cases,left-sided in 10 cases,bilateral in 1 case,and not palpable in 2 cases of hyperthyroidism(grade 1).There were 9 cases of solitary nodule and 15 cases of multiple nodules.The nodules were cystic in 5 cases,solid in 13 cases,and mixed in 6 cases,with 1~4 cm in diameter.Preoperative diagnoses included 9 cases of thyroid adenoma,15 cases of nodular goiter,and 2 cases of primary hyperthyroidism.Results The thyroidectomy was performed successfully under endoscope in 25 cases,with an operation time of 50~210 min(mean,112 min),including 4 cases of tumor enucleation,10 cases of unilateral partial thyroidectomy,8 cases of bilateral partial thyroidectomy,and 3 cases of bilateral subtotal thyroidectomy with isthmus resection.A conversion to open surgery was required in 1 case owing to thyroid carcinoma with trachea involvement.Pathological findings showed 4 cases of thyroid adenoma,18 cases of nodular goiter,2 cases of primary hyperthyroidism,and 2 cases of thyroid carcinoma.The drainage tubes were removed at 24~48 hours after operation.No nerve or parathyroid injuries occurred.The length of postoperative hospital stay was 3~6 d(mean,4.2 d).Follow-up observations in 25 cases for 3~33 months(mean,13 months) revealed no local recurrence.The patients were satisfied with cosmetic effects.The 2 cases of thyroid carcinoma were followed for 9 and 11 months,respectively,presenting no recurrence or metastasis.Conclusions Endoscopic thyroidectomy via areola of breasts approach is feasible and effective,offering satisfactory cosmetic outcomes.

OBJECTIVE:To study the relevance between HLA-B27 gene and ankylosing spondylitis in Jiangxi province,and to discuss the diagnostic significance to ankylosing spondylitis.METHODS:A total of 1246 patients with suspected ankylosing spondylitis and related diseases were collected from the First Affiliated Hospital of Nanchang University from October 2007 to December 2008.Among all cases,323 were diagnosed as ankylosing spondylitis,and other 923 were rheumatoid arthdtis or related diseases.A total of 135 healthy subjects were collected as control group.Sequence-specific primer-polymerase chain method(PCR-SSP)was used to detect HLA-B27 gene in 1246patients and 135 healthy controls.The distribution of HLA-B27 gene,correlation between HLA-B27 gene and age,and relation between ankylosing spondylitis and HLA-B27 gene were studied.RESULTS:Total positive rate of HLA-B27 gene was 32.5%in 1246 patients with suspected ankylosing spondylitis.3.7%in 135healthy controls.and 91.6%in 323 patients with ankylosing spondylitis,respectively.The positive rate and incidence rates of male were significantly higher than female(P＜0.01)and mainly concentrated in the age of adolescence.The sensitivity of HLA-B27 genewas 91.64%and the specificity was 88.19%in patients with ankylosing spondylitis.CONCLUSION:HLA-B27 gene was highly correlated with ankylosing spondylitis in Jiangxi province,which was the same as other regions,suggesting that HLA-B27 gene is significance for diagnosis of ankylosing spondylitis in an eedy phase.

The changes of leucocyte deformability (LD) and effects of PGMS and PSS on LD in patients with acute cerebral infarction (ACT) were observed. The results showed that leucocyte filtration index (IF) was higher significantly in patients with ACI than that in the normal control ( P

BACKGROUND: This study aimed to determine the reasons for conversion and elucidate the safety and efficacy of transition to tenofovir alafenamide/emtricitabine/bictegravir sodium (TAF/FTC/BIC) in highly active antiretroviral therapy (HAART)-experienced HIV-infected patients in real-world settings. METHODS: We conducted a retrospective cohort study. The treatment conversion rationales, safety, and effectiveness in 1684 HIV-infected patients with previous HAART experience who switched to TAF/FTC/BIC were evaluated at Beijing Ditan Hospital from September 2021 to Auguest 2022. RESULTS: Regimen simplification (990/1684, 58.79%) was the most common reason for switching, followed by osteoporosis or osteopenia (375/1684, 22.27%), liver dysfunction (231/1684, 13.72%), decline in tenofovir alafenamide/emtricitabine/elvitegravir/cobicistat (TAF/FTC/EVG/c) with food restriction (215/1684, 12.77%), virological failure (116/1684, 6.89%), and renal dysfunction (90/1684, 5.34%). In patients receiving non-nucleotide reverse transcriptase inhibitors (NNRTI)-containing regimens, lipid panel changes 1 year after switching indicated a difference of 3.27 ± 1.10 mmol/L vs . 3.40 ± 1.59 mmol/L in triglyceride ( P  = 0.014), 4.82 ± 0.74 mmol/L vs . 4.88 ± 0.72 mmol/L in total cholesterol ( P  = 0.038), 3.09 ± 0.70 mmol/L vs . 3.18 ± 0.66 mmol/L in low-density lipoprotein ( P  <0.001), and 0.99 ± 0.11 mmol/L vs . 0.95 ± 0.10 mmol/L in high-density lipoprotein ( P  <0.001). Conversely, among patients receiving booster-containing regimens, including TAF/FTC/EVG/c and lopinavir/ritonavir (LPV/r), lipid panel changes presented decreased trends. We also observed an improved trend in viral load suppression, and alanine transaminase (ALT), aspartate transaminase (AST), estimated glomerular filtration rate (eGFR), and serum creatinine levels after the transition ( P  <0.001). CONCLUSION The transition to TAF/FTC/BIC demonstrated good treatment potency. Furthermore, this study elucidates the motivations behind the adoption of TAF/FTC/BIC in real-world scenarios, providing clinical evidence supporting the stable conversion to TAF/FTC/BIC for HAART-experienced patients.

Partial least square (PLS) combining with Raman spectroscopy was applied to develop predictive models for plasma paclitaxel concentration detection. In this experiment, 312 samples were scanned by Raman spectroscopy. High performance liquid chromatography (HPLC) was applied to determine the paclitaxel concentration in 312 rat plasma samples. Monte Carlo partial least square (MCPLS) method was successfully performed to identify the outliers and the numbers of calibration set. Based on the values of degree of approach ( ), moving window partial least square (MWPLS) was used to choose the suitable preprocessing method, optimum wavelength variables and the number of latent variables. The correlation coefficients between reference values and predictive values in both calibration set ( ) and validation set ( ) of optimum PLS model were 0.933 1 and 0.926 4, respectively. Furthermore, an independent verification test was performed on the prediction model. The results showed that the correlation error of the 20 validation samples was 9.36%±2.03%, which confirmed the well predictive ability of established PLS quantitative analysis model.
