Objective To investigate the risk factors of hypoparathyroidism after total thyroidectomy and bilateral central lymph node dissection in patients with papillary thyroid carcinoma.Methods Data of patients with PTC who accepted total thyroidectomy and bilateral central lymph node dissection in the Department of Thyroid Surgery from Jan.2013 to Jun.2016 were collected and analyzed retrospectively.The patients were divided into normal group,transient hypoparathyroidism group and permanent hypoparathyroidism group according to the level of serum parathyroid hormone within 6 months after surgery.Clinical data were collected for comparison between the three groups.The risk factors of hypoparathyroidism were indentified with univariate analysis and multivariate analysis.Results A total of 468 patients,241 in the normal group and 227 in the hypoparathyroidism group (220 in the transient hypoparathyroidism group and 7 in the permanent hypoparathyroidism group),were included in the study.Univariate analysis showed that without application of carbon nanoparticles (P=0.04) and autotransplantation of more than one parathyroid gland (P＜0.001) were risk factors of hypoparathyroidism,and without application of carbon nanoparticles (P=0.047),incidental parathyroidectomy of one parathyroid gland (P=0.04),gross extrathyroidal extension (P=0.006) and c N1a were risk factors of permanent hypoparathyroidism.Multivariate analysis showed that without application of carbon nanoparticles (OR,0.437;95％ CI,0.243-0.789;P=0.006) and autotransplantation of more than one parathyroid gland (OR,3.025;95％ CI,1999-4579;,P=0.000) were independent risk fact ors of hypoparathyroidism,and without application of carbon nanoparticles (OR,0.197;95％ CI,0.039-0.982;P=0.048) and gross extrathyroidal extension (OR,12.381;95％ CI,1.432-107.036;P=0.022) were independent risk factors of permanent hypoparathyroidism.Conclusion When total thyroidectomy and bilateral central lymph nodes dissection were performed,carbon nanoparticles were routinely applied.Although autotransplantation of more than one parathyroid gland can increase the incidence of transient hypoparathyroidism,it can reduce the incidence of permanent hypoparathyroidism.If extrathyroidal extension is suspected,hypoparathyroidism should be emphasized to patient,and accurate operation should be done to reduce the incidence of hypoparathyroidism.

Objective To evaluate the quality of life for tuberculosis patients after anterior debridement, autograft bone fusion and anterolateral fixation operation. Methods 17 cases of thoracolumbar spinal tuberculosis were treated surgically from January 2008 to March 2011. All the cases underwent anterior debridement, autograft bone fusion and anterolateral fixation operation. MOS health survey 36-item Short Form (SF-36), Japanese Orthopaedic Association Scores (JOA) and Visual Analogue Scale (VAS) were used to evaluate the quality of life, spine function and pain symptom before and 1 and 6 months after surgery. Results Compared to the results 1 month after surgery, the scores of physical function (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social function (SF), role emotional (RE), and mental health (MH), and JOA subjective symptoms, JOA clinical signs, and JOA daily activity limitation, and VAS improved (P<0.05) 6 months after surgery; compared to pretreatment, the scores of PF, BP, GH, VT, SF, and MH, and JOA subjective symptoms, JOA clinical signs, and JOA daily activity limitation, and VAS improved (P<0.05). Conclusion The anterior debridement, autograft bone fusion and anterior fixation operation is effective to improve the quality of life, spine function and pain symptom for tuberculosis patients.

Objective To study the expression of leukemia-related protein 16 (LRP16) in human pituitary prolactin adenomas (PRL adenomas), and the relationship between LRP16 and estrogen receptorα (ERα).Methods From October 2009 to September 2014, thirty-one adult patients diagnosed and pathologically confirmed as pituitary prolactin (PRL) adenomas (observation group) and 22 pituitary non-PRL adenomas (control group) in the Chinese PLA General Hospital were verified by the pathological examination. Immunohistochemical method was used to detect the expression levels of LRP16, PRL and ERα.Results Of the patients in observation group, those aged under 30 were predominantly females, while male patients were more common in those aged over 30. LRP16 positively existed in 26 cases (83.9%, 26/31), and ERα was positive in 28 cases (90.3%, 28/31), the both ratios were significantly higher than those in control group. ERα and LRP16 increased synchronously both in expressive content and intensity, showing a certain positive correlation between them.Conclusions Higher body mass index may be a high-risk factor badly affected the occurrence, development and prognosis in male patients with pituitary PRL; LRP16 may take part in the proliferation and formation of pituitary PRL adenomas through ERα.

Objective:To investigate the expression profile variation of long non-coding RNA( lncRNA) in the peripheral blood mononuclear cells of rheumatoid arthritis ( RA ) and healthy controls, and explore the role of lncRNA in the pathogenesis of RA.Methods:A total of 12 RA patients and 11 age-matched healthy controls from University Hospital of Hubei University for Nationalities were recruited.Using lncRNA microarray technology to detect differently expressed lncRNAs in 3 cases of RA PBMCs and 3 cases of healthy controls.GO and Pathway analysis was performed.The coding-non-coding gene co-expression networks of lncRNA and mRNA was constructed based on the correlation analysis,and then searched lncRNA in pathogenesis of RA through the cis-analysis and trans-analysis.Results:A total of 1 615 deregulated lncRNAs and 878 deregulated mRNAs were detected in RA patients.GO analysis of different expressed mRNA may involve in metal ion binding,protein kinase binding,nucleotide binding,regulation of transcription,et al.Pathway analysis of different expressed mRNA may involve in TNF signaling pathway,B cell receptor signaling pathway,pancreatic cancer,system lupus erythematosus endometrial cancer,et al.REL,SMAD3 and ETS1 may play an important role in the pathogenesis and development of RA through cis-analysis and trans-analysis.As the NONHSAG027875,FR378506 and NONHSAT031501 also had the similar function,and they may be related to the pathogenesis and development of RA.Conclusion:Differentially expressed lncRNAs may exert a partial role in RA,and may provide potential targets for future treatment of RA.

Hypoparathyroidism is one of the most common complications of thyroid surgery. Permanent hypoparathyroidism would bring great pain to patients, seriously affect the postoperative quality of life, is becoming the source of medical disputes. Parathyroid autotransplantation can effectively reduce the incidence of postoperative permanent hypoparathyroidism. However, there are still some dispute about the choice, including the time, the number, the method and the location of parathyroid autotransplantation, which need to be further researched. As a result, the program and survival rate of parathyroid autotransplantation will be optimized and improved, respectively.

Pituitary stalk interruption syndrome (PSIS) is a newly discovered rare endocrinological syndrome characterized by structrual defect of pituitary and multiple deficiencies of a series of hypothalamic hormones, and thus leading to a cluster of clinical symptoms. This review will illustrate the genetic pathogenic factors influence on embryonic development, and briefly introduce the current studies of Whole-Exome Sequencing on PSIS.

Objective To observe the effects of 12-week pilates exercise and trunk strength training on the scores of visual analog scale(VAS)and Roland-Morris disability questionnaire(RMDQ),trunk extension/flexion strength and dynamic balance of female college students with chronic non-specific low back pain(CNSLBP),so as to offer a practical-based evidence for the rehabilitation treatment for female college students with CNSLBP.Methods A total of 45 female college students with CNSLBP were randomly divided into pilates(n=22)and strength training groups(n=23).Then,the scores of VAS and RMDQ,trunk extension/flexion strength and dynamic balance were measured before and after the exercise.Results After the 12-week exercise program,compared with the pre-exercise period,the VAS and RMDQ scores in the pilates and strength training groups were significantly decreased;the extensor peak torque(EPT)at 30°/s and 90°/s angular velocities in both groups and the flexor peak torque(FPT)at 90°/s angular velocities in the Pilates group were significantly increased,and the ratio of flexor/extensor(F/E)at 30°/s and 90°/s angular velocities in both groups were significantly decreased.In the eyes-open condition,only the anterior/posterior stability index(APSI)significantly decreased in the Pilates group.With eyes closed,the APSI,stability index(SI),and medial/lateral stability index(MLSI)significantly decreased in the pilates group,and only the APSI significantly decreased in the strength training group.After 12-week exercise,compared with strength training group,the VAS scores and F/E at 30°/s and 90°/s angular velocities decreased significantly in the pilates group,and EPT at 30°/s and 90°/s angular velocities increased significantly.In the eyes-closed condition,the SI,APSI,and MLSI in the pilates group were significantly lower than those in strength training group.Conclusions Compared with strength training,pilates exercise can significantly increase and balance the trunk flexion/extension muscle strength of female college students with NSLBP,enhance dynamic balance ability under eyes-closed conditions,and improve the low back pain of CNSLBP female college students with CNSLBP.

Objective: To compare the effects of aerobic exercise at maximal fat oxidation (FATmax) and FATmax intensity exercise combined with resistance training (RT), and dietary restriction on the body composition, vascular endothelial function and ferroptosis in obese female university students, so as to provide a reference for exploring the mechanisms by which exercise improves vascular endothelial function. Methods: From February to May 2024, 70 obese female university students were recruited from Shanxi University and randomly divided into control group ( n =24), FATmax group ( n =24) and FATmax+RT group ( n =22). From March 4 to May 26, 2024 control group maintained their normal living habits, FATmax group performed aerobic exercise at FATmax intensity three times per week for 60 minutes per session; FATmax +RT group performed combined aerobic and resistance exercise at FATmax intensity three times per week for 60 minutes per session. The daily dietary calorie intake for all groups was determined according to resting energy expenditure. Body composition, vascular endothelial function and ferroptosis were measured before and after the intervention. Results: After 12 weeks of intervention, there were statistically significant differences in body mass, BMI, body fat, waist hip ratio and muscle mass among the three groups ( F =10.93, 5.88, 65.28, 21.14, 2.25, all P < 0.05). Compared with the control group, participants in both the FATmax group and the FATmax+RT group showed significant reductions in body weight, BMI, body fat and waist hip ratio (all P <0.05). Body fat and waist hip ratio in FATmax+RT group were lower than those in FATmax group, and muscle mass was higher than those in FATmax group and control group (both P <0.05). After 12 weeks of intervention, significant differences were observed among the three groups in serum NO, GSH, serum ferritin levels and FMD ( F = 9.14, 9.67, 4.78, 135.70, all P <0.05). Compared with the control group, the serum NO, GSH levels and FMD significantly increased, and the serum ferritin level decreased (all P <0.05) of obese female university students in FATmax group and FATmax+RT group. Serum GSH level and FMD increased and serum ferritin level decreased in FATmax +RT group when compared with FATmax group (all P <0.05). Conclusions With the same exercise training duration and frequency, FATmax intensity aerobic exercise, alone or combined with resistance and dietary restriction, can significantly improve the body composition, vascular endothelial function and inhibit ferroptosis of obese female university students. However, FATmax intensity aerobic exercise combined with resistance training has more pronounced effects.

Objective:To investigate the effect of 25 hydroxyvitamin D [25 (OH) D] on postoperative parathyroid function in patients with papillary thyroid carcinoma (PTC) .Methods:426 patients who diagnosed as PTC and underwent at least total thyroidectomy plus central lymph node dissection (including lateral lymph node dissection) in Center of Thyroid and Parathyroid Surgery of West China Hospital, Sichuan University, from Jun. 2017 to Sep. 2019 were retrospectively analyzed. Among them, 313 were women and 113 were men, they were divided into vitamin D deficient (VDD) group ( n=297) and normal group ( n=129) according to preoperative 25 (OH) D levels ≤ 20ng/ml and > 20ng/ml. SPSS 23.0 statistical software was used for data processing. Pearson χ2 test or Fisher exact test were used to compare the incidence of clinical hypoparathyroidism, biochemical temporary and biochemical permanent hypoparathyroidism between the two groups. Univariate and multivariate logistic regression analysis were used to analyze the related factors of postoperative hypoparathyroidism between the two groups. Results:Preoperative 25 (OH) D level was significantly correlated with postoperative biochemical temporary hypoparathyroidism ( P=0.04, OR=1.11) . Compared with patients with adequate preoperative vitamin D, preoperative vitamin D deficiency increased the risk of biochemical transient hypoparathyroidism by 6.67 times ( P=0.03;OR=6.67) . There was no significant correlation between preoperative vitamin D deficiency and early postoperative clinical hypoparathyroidism (2.7% vs 3.9%, P=0.55) . Conclusion:Correction of vitamin D deficiency before operation may reduce the incidence of postoperative temporary hypoparathyroidism caused by 25 (OH) D deficiency.
