Parathyroid hormone (PTH) exerts multiple effects such as regulating bone remodeling, promoting angiogenesis, etc., and it is an active factor with great application potential for bone repair. In recent years, with the development of scaffold material loading strategies and parathyroid hormone-related peptides (PTHrPs), in situ loading of PTH or PTHrPs on scaffold materials to promote bone defect healing gradually becomes possible. Based on the current status and challenges of intermittent PTH (iPTH) for bone tissue engineering, the review summarizes the in-situ application strategies of PTH and the construction of PTHrPs as well as current problems and further directions in this field, with a view to propel the clinical application of scaffold materials loaded with PTH or PTHrPs in situ.
Objective To evaluate whether the classification of parathyroid can be used to evaluate how difficult it is that the parathyroid glands get preserved in situ during thyroid surgery. Methods Clinical date were retrospectively collected from the patients with thyroid nodules, who had undergone the initial thyroidectomy in the Department of Thyroid Surgery, West China Hospital of Sichuan University between January 2014 and June 2016. The number of parathyroid glands was counted according to the classification of parathyroid. It got comparative analysis that the rates of parathyroid glands in situ among the different types. Results A total of 996 patients were included in the study, and 3 269 pieces of parathyroid glands were identified. The mean number of parathyroid identification was 3.3 pieces. These parathyroid glands consisted of 77.5% (2 532/3 269) type A and 22.5% (737/3 269) type B. The rate of parathyroid glands in situ was 77.1% (1 951/2 532) in type A, and 80.7% (595/737) in type B, the difference was significant (P=0.03). And the rate of parathyroid glands in situ in type A1 was significantly higher than that in type A2 (80.5%vs 21.4%,P<0.001). The parathyroid of type A3 couldn’t get preserved in situ. The rate of superior parathyroid glands in situ in type B1 was higher than that in type A1 (97.5%vs 93.7,P<0.01). But the rate of inferior parathyroid glands in type B1 was closed to that in type A1 (62.2%vs 65.7%,P=0.23), and both the rates were significant less than that in type B2 (86.0%) and in type B3 (90.2%),PA1vs B2=0.001,PA1vs B3<0.001,PB1vs B2=0.004,PB1vs B3=0.001. Conclusion The classification of parathyroid can be used to evaluate effectively how difficult it is that the parathyroid glands get preserved in situ during thyroid surgery.
Objective To evaluate the diagnostic significance and to analyze reasons of false negative cases forpreoperative ultrasonography, 99Tcm-sestamibi scintigraphy (MIBI scintigraphy), and CT in primary hyperparathyroidism(PHPT). Methods Clinical data of 69 patients with PHPT, who underwent operation in Affiliated Shengjing Hospital of China Medical University between Jan. 2003 and Aug. 2012 were retrospectively analyzed. Results There were 76 parathyroid lesions in 69 PHPT patients proved by operation and pathology, including 58 cases of parathyroid adenoma with 60 lesions, 7 cases of parathyroid hyperplasia with 11 lesions, and 4 cases of parathyroid carcinoma with 5 lesions. The sensitivity of ultrasonography, CT, and 99Tcm-MIBI scintigraphy were 81.94% (59/72), 61.76% (21/34), and 69.57% (16/23), the accuracy of 3 kinds of tests were 78.67% (59/75), 61.76% (21/34), and 66.67% (16/24), the positive predictive value were 95.16% (59/62), 100% (21/21), and 94.12% (16/17) respectively. There was significant differ-ence only between ultrasonography and CT in sensitivity (P=0.03), no other significant difference was found (P>0.05).Conclusions Ultrasonography is complementary to 99Tcm-MIBI scintigraphy, but CT has little significance in diagnosis of PHPT. Both of ultrasonography and 99Tcm-MIBI scintigraphy should be used before operation routinely to localize parathyroid lesions.
ObjectiveTo understand the methods of judging the blood supply of parathyroid during thyroidectomy at home and abroad in recent years. MethodThe literature on parathyroid blood supply was collected, the research progress was reviewed, and the advantages and disadvantages of related methods were analyzed. ResultsIn recent years, near-infrared fluorescence, laser speckle contrast imaging and other technologies had been applied. They showed better advantages as compared with naked eye observation. The research on parathyroid blood supply at home and abroad was still in its infancy, and more clinical samples and related equipment optimization were still needed. ConclusionFluorescence imaging technology has a certain auxiliary role in the judgment of intraoperative parathyroid blood supply and can reduce the incidence of hypoparathyroidism to a certain extent.
This is the first successful case expriences,a method of the procurement of the fetal cadavertic multiple argans for transplantation of the pancreas and thyroid-pararthyroid glands was produced. The liver,pancreas,duodenum,spleen,and both kidneys were harvested en bloc by a group of surgeons,and the right hem-ithyroid-parathyroid glands with pedicle of thd blood vessels wre removed by another group.The pancreas together with the spleen were transplanted to a patient having diabetes mellitus. The thyroid-parathyroid glands were given to another case with bypothyroidism and hypoparathyroidism.Both cases had good results.This method had dicreased the warm ischemia of the transplants,and could provide liver,pancreas,spleen,kidneys and thyroid-parathyroid glands to solve the problem of shortage of fetal organs.
Objective To investigate the function and survival of parathyroid tissue transplanted into the rectus of rat by different pre-treatment. Methods Male,adult Wistar rats (seventy)as donors and adult SD rats (thirty-five)as receptors. Model rats were established by resection of parathyroid and randomly divided into five groups (digital random method):direct transplantation group, high-oxygen culture group, ciclosporin A (CsA) group, 60Co irradiated group, and integrated treatment group. Each receptor received four PTG from two donors and the PTG were transplanted into the rectus of the receptors. Changes in concentration of serum calcium and PTH at different time points before and after parathyroid transplantation in each group recipient rats were observed. Results Serum calcium and PTH could reach or remain normal level after thyroid tissue transplantation in all groups in 1 week after operation, which significantly differed from those of pre-transplanted (P<0.01). The survival time among the five groups were different: the duration for keeping serum calcium and PTH at normal level(only 3 week and 4 weeks)in direct transplantation group was shortest than that in high-oxygen culture group (5 weeks and 8 weeks), CsA group (6 weeks and 8 weeks), 60Co irradiated group (5 weeks and 7 weeks), and integrated treatment group (5 weeks and 9 weeks). Compared with direct transplantation group, the levels of serum calcium and PTH in high-oxygen culture group,CsA group,60Co irradiated group, and integrated treatment group were significantly higher in 4-9 weeks point (P<0.05, except high-oxygen culture group in 9 weeks and 60Co irradiated group in 8 weeks after operation had no significant difference). Compared with integrated treatment group, the levels of serum calcium and PTH in high-oxygen culture group,CsA group, and 60Co irradiated group were significantly lower in 7-9 weeks point (P<0.05). Conclusions PTG tissues transplanted in rectus can maintain serum calcium level at normal range,and measurement on graft or receptors can prolong the survival period of parathyroid graft. Tissue transplantation of parathyroid after culture may provide a potent way to cure hypothyroidism.

Objective To compare the clinical features and surgical effect between ectopic and orthotopic parathyroid lesions. Methods The clinical data of 136 patients with parathyroid lesions who had undergone parathyroidectomy between May 2010 and May 2017 were retrospectively analyzed. Results The ectopic parathyroid location was detected in 20 patients (14.7%) of the 136 patients with parathyroid lesions. Of the 20 patients, prevalence of superior mediastinal ectopic lesions accounted for 30.0% (6/20), prevalence of thyrothymic ligament accounted for 20.0% (4/20), prevalence of intrathymic accounted for 15.0% (3/20), prevalence of tracheoesophageal groove accounted for 25.0% (5/20), prevalence of submandibular accounted for 5.0% (1/20), prevalence of carotid sheath accounted for 5.0% (1/20), respectively. Patients with ectopic lesions had significantly higher level of serum parathyroid hormone (PTH) and alkaline phosphatase (AKP) than patients with orthotopic parathyroid lesions (P≤0.05). In addition, osteitis fibrosa cystica of metabolic bone disease was significantly more frequent in patients with ectopic parathyroid lesions than those with orthotopic parathyroid lesions (P=0.04). Preoperative ultrasonography had a sensitivity of 50.0% (10/20) for ectopic lesions and 90.1% (100/111) for orthotopic lesions. Preoperative 99Tcm methoxyisobutylisonitrile (99Tcm-MIBI) had a sensitivity of 100% (19/19)for ectopic lesions and 95.3% (101/106) for orthotopic lesions. Preoperative CT had a sensitivity of 81.3% (13/14) for ectopic lesions and 93.6% (102/109) for orthotopic lesions. Preoperative combination examination had a sensitivity of 100% (20/20) for ectopic lesions and 99.1% (108/109) for orthotopic lesions. Of the 20 patients with ectopic leisions, 17 patients (85.0%) had undergone 1 time of operation, 2 patients (10.0%) had undergone twice operations, 1 patient (5.0%) had undergone trice operations. The onset of hypocalcemia happened in 13 patients (65.0%) after operation. Of 116 patients with orthotopic leisions, only 1 patient had twice operations, the onset of hypocalcemia happened in 74 patients (63.8%) after operation. The reoperation rate of orthotopic leisions was lower than that of patients with ectopic leisions (P=0.01), but there was no significant difference on the incidence of hypocalcemia (P=0.92). Excessive bleeding and recurrent laryngeal nerve injury didn’t happen after all operations. Of 136 patients, 111 patients had followed-up, among which 17 patients with ectopic leisions and 94 patients with orthotopic leisions. During the followed-up period, there were no recurrence happened. Conclusions The ectopic parathyroid lesions are associated with higher serum PTH and AKP levels and more frequent metabolic bone disease in comparison with the orthotopic parathyroid lesions, as well as high reoperation rate. Combined examination, including cervical ultrasonography, 99Tcm-MIBI, and cervical enhanced CT are needed for preoperative location. Parathyroid lesions resection is the main surgical approach, and patients with parathyroid lesions are prone to be onset of hypocalcemia.
