Sestamibi Single-Positron Emission Computed Tomography/Diagnostic-quality Computed Tomography for the localization of abnormal parathyroid glands in patients with primary hyperparathyroidism: What clinicopathologic factors affect its accuracy?

PURPOSE: Sestamibi Single-Positron Emission Computed Tomography/Diagnostic-quality Computed Tomography (MIBI-SPECT/CT) is a common technology used for primary hyperparathyroidism (PHPT) localization in clinical practice. However, the clinicopathologic factors affecting the accuracy of MIBI-SPECT/CT and the potential limitations remain unclear. METHODS: Retrospectively enrolled PHPT patients (n = 280) were analyzed from August 2017 to December 2019. RESULTS: Of 96 patients with PHPT (mean age, 54 years; 63 females), 17 had discordance between MIBI-SPECT/CT and intraoperative findings. Among the 17 patients with discordance, 58.8% had major discordance, which occurred in most patients with multigland disease (MGD). Compared with concordant patients, discordant patients exhibited increased frequencies of autoimmune thyroid disease (29.4% vs 10.1%, p = 0.035), MDG (41.2% vs 3.8%, p = 0.035), higher PTH (296 pg/mL vs 146 pg/mL; p = 0.012),and lower phosphorus levels (0.77 mmol/L vs 0.90 mmol/L; p = 0.024). MDG (odds ratio [OR], 16.95; 95% CI 2.10-142.86), parathyroid lesion size of 12 mm or less (OR, 6.93; 95% CI 1.41-34.10), and a PTH level higher than 192.5 pg/mL (OR, 12.66; 95% CI 2.17-71.43) were independently associated with discordant MIBI-SPECT/CT results. CONCLUSION: MGD was most strongly associated with discordance between MIBI-SPECT/CT and intraoperative findings followed by a PTH level higher than 192.5 pg/mL and parathyroid lesion size of 12 mm or less. Surgeons should recognize these potential limitations, which may improve the preoperative procedure by encouraging further localization imaging and promptly facilitate intraoperative troubleshooting.

Xiangshao granules can relieve emotional symptoms in menopausal women: a randomized controlled trial.

OBJECTIVE: This study aimed to investigate the safety and efficacy of Xiangshao granules for treating emotional disorders in perimenopausal and postmenopausal women. METHODS: The current investigation was a double-blind, randomized, placebo-controlled, multicenter trial that included 300 perimenopausal and postmenopausal Chinese women aged 40-60 years. Participants received either a placebo (n = 150) or Xiangshao granules (n = 150) for 8 weeks. Outcome measures included Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale (HAMA) scores, which were assessed at baseline, 4 weeks, and 8 weeks. The primary efficacy variables were changes in HAMD and HAMA scores after 8 weeks. RESULTS: After 8 weeks, the mean HAMD scores decreased from 15.0 to 7.9 in the Xiangshao group and from 16.3 to 10.0 in the placebo group, and the respective mean reductions in HAMA scores were from 16.0 to 8.5 and from 17.1 to 10.9. Clinical improvements in symptoms of both depression and anxiety after 8 weeks differed significantly in the two groups (p < 0.05). The cure rate was significantly higher in the Xiangshao group. There were no significant differences in the rates of adverse events in the two groups. CONCLUSIONS: Xiangshao granules can relieve symptoms of depression and anxiety significantly and safely.

The protective effect of Shenfu injection against elderly severe pneumonia.

OBJECTIVE: The purpose of this study is to investigate the effect of Shenfu injection (SFI) on the tumor necrosis factor-α (TNF-α) and the interleukin (IL-6, IL-8, IL-10) of elderly patients who suffered from severe pneumonia. METHODS: From June 2012 to September 2014, we performed in our department 89 cases of elderly patients with severe pneumonia. These patients were randomly divided into two groups: the treatment group (45 cases) and the control group (44 cases). The control group was given the treatment of anti-infection, reducing sputum, and support therapy, while the treatment group was fed by SFI intravenously based on the control group. The TNF-α and the interleukin were detected by enzyme-linked immunosorbent assay (ELISA). Meanwhile, the changes in the inflammatory response indicators, the blood gas analysis, and the parameters of vital signs were measured and compared before and after therapy. RESULTS: Prior to treatment, there is no significant difference between the treatment group and the control group (p > 0.05); after the treatment for 7 days, the levels of TNF-α, IL-6, and IL-8 were significantly decreased, while the level of IL-10 was obviously increased. The APACHE II score was significantly decreased in comparison to that before the treatment (p < 0.05), and the time of mechanical ventilation, the duration of time in ICU, and the application time of vasoactive drugs were notably shortened. CONCLUSION: The application of Shenfu injection exhibited a positive and effective effect on removing the inflammation media during the treatment of elderly severe pneumonia.

Polymorphisms of CASR gene increase the risk of primary hyperparathyroidism.

OBJECTIVE: To evaluate correlations between polymorphisms of calcium-sensing receptor (CASR) gene [A986S (rs1081725), R990G (rs1042636) and Q1011E (rs1801726)] and the risk of primary hyperparathyroidism (PHPT) among human population. METHODS: Relevant studies were retrieved from online databases using computer-based search strategies, which were then supplemented by manual search strategies. Case-control studies related to our topic were identified based on strict inclusion and exclusion criteria. Statistical analyses were conducted using the Comprehensive Meta-analysis 2.0 (Biostat Inc., Englewood, NJ, USA). RESULTS: We retrieved 202 studies from online databases and other sources initially and eventually enrolled six studies into our meta-analysis. These six studies contained a sum of 693 PHPT patients and 1252 healthy controls. Our meta-analysis results showed that single nucleotide polymorphisms (SNPs) of CASR gene A986S (rs1081725) and R990G (rs1042636), but not Q1011E (rs1801726), may increase the risk of PHPT [A986S (rs1081725): allele model: P = 0.013; dominant model: P = 0.044; R990G (rs1042636): allele model: P = 0.023; dominant model: P = 0.026)]. Subgroup analyses based on ethnicity showed that among Asians, A986S (rs1081725) increased the PHPT risk (P = 0.04) under the allele model, but not under the dominant model. Among Caucasians, there was no association between gene frequencies and PHPT under both the allele and dominant model. In Asians, no significant association was observed between R990G (rs1042636) and PHPT risk, but in Caucasians, R990G (rs1042636) significantly increased the incidence of PHPT [R990G (rs1042636): allele model: P = 0.015; dominant model: P = 0.009)]. CONCLUSION: Our results indicate that SNPs of CASR gene A986S (rs1081725) and R990G (rs1042636) may increase the risk of PHPT, and the polymorphisms can potentially be used as important biological markers for early diagnosis of PHPT.
