Chinese Journal of Endocrinology and Metabolism 2015;31(4):300-305
Objective To summarize the clinical manifestations,diagnosis and treatment of the primary hyperparathyroidism (PHPT).Methods The clinical data of 89 patients with PHPT admitted during 1991 to 2013 were retrospectively analyzed.Results The mean age of the 89 patients was (44.7 ± 15.8) years (13-86 years),male to female ratio was 1 ∶ 2.1.79% of the 89 patients were symptomatic.62% of the 89 patients had been misdiagnosed.52% had been misdiagnosed as kidney stones or bone diseases (fracture,tumor,and metabolic bone disease).The remaining subjects had been misdiagnosed as peptic ulcer,rheumatoid arthritis or pancreatitis.The median serum parathyroid hormone (PTH) level in 88 patients was 697.3 pg/ml (26.4-5 000.0 pg/ml,n =88),the mean serum calcium level was (3.03 ± 0.56) mmol/L (n =88).The 24 h urine calcium was (10.02 ± 4.73)mmol/24 h (n =36).The sensitivity of localization of the parathyroid lesions with technetium-99m methoxy-isobutylisonitrile (99mTc-MIBI) was 96%,being higher than ultrasound (71%),CT (71%),and MRI (72%) (P<0.05,respectively).79 cases had been treated surgically.The median serum PTH level was 748.2 pg/ml (46.1-5 000.0 pg/ml) before surgery,79.9 pg/ml (11.35-838.0 pg/ml) 15 minutes after surgical removal of the lesions (P<0.05 vs preoperative) and 22.9 pg/ml (2.3-1 203.0 pg/ml) on the first postoperative day (P<0.05 vs preoperative).Serum calcium was (3.03 ± 0.56) mmol/L before surgery,(2.25 ± 0.37) mmol/L on the first postoperative day (P<0.05 vs preoperative) and (2.08 ± 0.36) mmol/L on the second postoperative day (P< 0.05 vs preoperative).After the operation,42 cases(53%) had perioral and limb numbness,2 cases (3%) had hoarseness of voice and bucking while drinking,1 case(1%) had tetany.All these symptoms were improved after calcium supplementation.67 patients (85%) had been diagnosed as parathyroid adenoma pathologically,7 patients (9%) as hyperplasia,3 patients (4%)as cysts,and 2 patients (3%) as carcinoma.Among 67 cases of adenomas,62 cases had a single parathyroid adenoma,1 case with multiple parathyroid adenomas,and 4 cases with ectopic parathyroid adenomas.The ectopic lesions were located below the thyroid,in the rib cage,left mediastinum,and above the sternum.Conclusions The majority of domestic PHPT was symptomatic.Delayed diagnosis of PHPT is still very frequent.The clinical presentations of PHPT are variable,determination of serum calcium and PTH level simultaneously is the keypoint for early identification and diagnosis of PHPT.The clinician should be familiar with the various clinical manifestations of PHPT and thus enhance understanding of pathogenesis of the disease.99mTc-MIBI scintigraphy remained the first choice of preoperative imaging localization of the parathyroid lesions,followed by ultrasound,CT,and MRI.Surgical removal of the lesions is effective and safe.

Objective To look for suitable short-term weight loss and long-term maintenance method for army cadres. Method A total of 142 patients with simple overweight and obesity were randomly selected as the research subjects, and were followed up for 2 years, 130 of them were valid for analysis, 97 were male, and 33 female, age 27-59 years, average(47.41±7.55)years. SPSS 16.0 was used for analysis. Repeated measurements analysis of variance was used for data analysis, K-related samples nonparametric test was used for enumeration data. Result The army cadres population weight intervention management model was divided into three stages. They were respectively intensified weight loss stage for 6 months, the consolidation of weight loss for 6 months, and self-management stage maintained for 12 months, totally 24 months. Variance analysis results showed that after two years of focused intervention and health management, the body mass index(BMI)fell from(27.42 ± 2.81)kg/m2 to(24.69 ± 2.63)kg/m2 (F=2 649.945, P<0.05), waist circumference decreased from(91.09±8.24)cm to(85.26±7.76)cm(F=1 207.248, P<0.05). Nonparametric test results showed that after two years intervention management the behavior patterns concerning physical exercise became better. Exercisers increased from 33.8%to 73.3%(H=68.448, P<0.05); proportion of smoking decreased from 38.5% to 20.0%(H=33.692, P<0.05); drinking alcohol decreased from 50.8%to 20.8%(H=59.128, P<0.05);high salt diet decreased from 39.2%to 23.1%(H=31.722, P<0.05);high-fat diet decreased from 46.2%to 27.7%(H=41.571, P<0.05). Conclusion The practice showed that the short-term intensified weight loss, long-term maintenance, exercise and psychological intervention, changed the cadres population from passive to active on the weight control and self-management with remarkable effects, therefore such intervention is worthy of promoting.

Objective To study the feasibility,effectiveness and safety of temporary pacing at the right ventricular outflow tract area in patients with inferior acute myocardial infarction(AMI)and two or three degree atrioventricular block(AVB). Methods Ninety-five patients with inferior AMI and two or three degree AVB admitted into Cangzhou People's Hospital were randomly divided into right ventricular apex pacing group(47 cases) and right ventricular outflow tract region pacing group(48 cases). Seldinger method was used to perform the right femoral vein puncture in which a 6F sheath tube was placed,and a diode temporary pacing electrode was introduced into it in the two groups. Under the X-ray guidance,in the right ventricular apex pacing group,the electrode was pushed from the inferior vena cava to enter into the right atrium,then cross the tricuspid and finally reach the right ventricular apical portion pacing. In the right ventricular outflow tract region pacing group,under the X-ray guidance, after the electrode was withdrawn and rotated slightly clockwise,it was sent forward to the right ventricular outflow tract region pacing. The duration from the puncture at the right femoral vein to the implanted electrode reaching the pacing region,the pacing threshold,the un-favorable pacing,the incidence of ventricular arrhythmia and prognosis were observed in the two groups. Results The pacing time and pacing threshold in right ventricular apex pacing group were obviously higher than those in the right ventricular outflow tract region pacing group〔pacing time(s):336±150 vs. 354±152,pacing threshold(V):0.9±0.4 vs. 0.7±0.3,both P<0.05〕. The mortality in intensive care unit (ICU)〔0(0/48)vs. 2.13%(1/47)〕,the incidence of bad pacing〔10.42%(5/48)vs. 17.02%(8/47)〕and ventricular fibrillation(VF),sustained ventricular tachycardia,contraction of non-sustained ventricular tachycardia or frequent ventricular premature beat(VPB)and other arrhythmia incidence of complications〔10.42%(5/48)vs. 12.77%(6/47)〕in the right ventricular outflow tract region pacing group were all lower than those in the right ventricular apex pacing group. Conclusion The application of right ventricular outflow tract pacing in patients with inferior AMI and two or three degree AVB is safe and effective,and its stability is fine.
