OBJECTIVE: To investigate the clinical manifestations and diagnostic method of hyperparathyroidism due to parathyroid tumors and to evaluate the intra-operative detection of parathyroid hormone in surgical treatment. METHOD: Thirty-seven cases with functional parathyroid tumors from January 2003 to October 2012 were retrospectively analyzed. The clinical manifestation, examination and operation method, changes of parathyroid hormone before and after operation were collected. RESULT: All cases were definitely diagnosed before operation. The sensitivity and the positively predictive values of neck ultrasonography were 86.5% and 97.6% respectively, and the same data of Tc-99m-MIBI was 97.2% and 100.0%. The PTH levels declined by 84.9% ten minutes after tumor resecting compared with the level before operation. The serum calcium and PTH returned to normal levels and symptomatic relief occurred after operation. CONCLUSION Recurrent bone disease, long-term urinary calculus and obscure gastrointestinal symptoms were common symptoms of hyperparathyroidism due to parathyroid tumors. The neck ultrasonography and Tc-99m-MIBI were suitable for location of parathyroid tumors. Surgical operation was an effective treatment for parathyroid tumor. Intra-operative PTH assay would be able to ensure the radical excision and the operative safety for functional parathyroid tumors.

Objective To investigate the effects of cholinergic pathway on acute renal tubular cell injury induced by acute oxygen and glucose deprivation. Methods Rat kidney macrophages were isolated and cultured for constructing macrophages and renal epithelial cells co-cultivating model of oxygen-glucose deprivation (OGD), and the model cells were divided into three groups: OGD alone group, acetylcholine (ACh 100μmol/L)+OGD group and ACh + galantamine (Gal 10μmol/L)+OGD group. The cells underwent OGD treatment for 1 hour, and normally cultured for 24 hours. The expressions of TNF alpha, IL-1 beta, and IL-10 in supernatant fluid were detected by ELISA, the renal tubular cell viability was determined by MTT assay, the expression of acetylcholine esterase (AChE) mRNA and protein were determined by RT-qPCR and Western blotting. The activity of AChE was determined by colorimetric method. Results The expressions of TNF alpha (pg/ml) in OGD, Ach+OGD group, Ach+Gal+OGD groups were 140.2±44.81, 119.46±4.42 and 103.31±1.62 respectively (P<0.05), those of IL-1β (pg/ml) were 172.26±13.51,144.34±5.53 and 119.37±11.42 respectively (P<0.05), and those of IL-10 (pg/ml) were 181.47±16.01, 173.62±10.12 and 188.36±8.73 respectively (P>0.05); The values of renal tubular cell proliferation were 55.02%±6.28%, 66.65%±6.47%, and 79.75%±4.22% respectively (P<0.01); the expressions of AChE mRNA in macrophages were 4.07±0.03, 4.22±0.15 and 3.98±0.29 respectively in the three groups (P>0.05); those of AchE protein were 0.66±0.07, 0.74±0.04 and 0.67±0.06 respectively (P>0.05); The activity of AChE (kU/L) was 0.51±0.02, 0.35±0.05 and 0.32±0.04 respectively (P=0.001, 0.001 and 0.368). Conclusions ACh and Gal could inhibit the secretion of inflammatory mediators and cholinesterase activity and can reduce the acute hypoxic renal tubular cell injury. The modulation of the cholinergic pathway in macrophages may be the important treatment method for acute renal injury in the future.

Objective:To construct a nomogram model for predicting frailty in elderly hypertensive patients, and to evaluate the discrimination and consistency of the model.Methods:A total of 317 patients with essential hypertension who were admitted to Hebei Eighth People′s Hospital from February 2021 to June 2022 were taken, they were divided into modeling group (190 cases) and verification group (127 cases) according to the proportion of 6∶4, the patients in the modeling group were divided into the asthenic group (45 cases) and the non asthenic group (145 cases) according to whether the patients in the modeling group had asthenia. The nomograph model was constructed based on the results of Logistic analysis.Results:The age, obesity or overweight ratio, diabetes ratio and systolic blood pressure in the frail group were significantly higher than those in the non-frail group: (76.25 ± 3.64)years vs.(70.44 ± 3.82) years, 51.11%(23/45) vs. 24.83%(36/145), 46.67%(21/45) vs. 17.24%(25/145), (156.46 ± 18.64) mmHg (1 mmHg = 0.133 kPa) vs. (143.25 ± 12.38) mmHg, and the mini-nutrition assessment summary form (MNA-SF) score was significantly lower than that in the non-frail group: (11.45 ± 2.06) scores vs. (13.12 ± 1.22) scores, there were statistical differences ( P<0.05). Logistic results showed that age, body mass index, diabetes, and systolic blood pressure were the risk factors for frailty ( P<0.05). The receiver operating characteristic (ROC) curve evaluation showed that the area under the curve (AUC) in the modeling group was 0.998, and AUC in the validation group was 0.954. The Hosmer-Lemeshow goodness of fit test showed: modeling group χ2 = 6.18, P = 0.627; validation group χ2 = 6.58, P = 0.582.
