This article reported a case of a male patient with primary hyperparathyroidism(PHPT) caused by an ectopic parathyroid adenoma in the anterior superior mediastinal. Hospital routine examinations indicated hyperlipidemia, hyperuricemia, type 2 diabetes with nephropathy, chronic kidney disease in stage Ⅳ, elevated PTH, hypercalcemia, hypophosphatemia, clinically highly suspected hyperparathyroidism. There was no obvious abnormality of parathyroid ultrasound, while 18F-FDG systemic metabolic imaging and 99mTc-MIBI dual-phase parathyroid imaging suggested that an ectopic parathyroid gland in the anterior superior mediastinal which was hyperactive. Evaluations of anterior pituitary function, pancreas, and endocrine-related hormones showed no obvious abnormalities, and thus we ruled out the possibility of multiple endocrine adenomas, combined with the patient′s symptoms and previous medical history, and ruled out the possibility of tertiary hyperparathyroidism, the patient was diagnosed as PHPT caused by the anterior superior mediastinal ectopic parathyroid adenoma. To restore the blood calcium to normal, the patient was treated with intravenous rehydration, diuresis, calcitonin to promote urinary calcium excretion, and zoledronic acid to inhibit bone resorption. Further thoracoscopic mediastinal tumor resection was performed, and the diagnosis of parathyroid adenoma was confirmed by pathology. All the indicators were normal and no recurrence of hyperparathyroidism was found during the follow-up. Integration of the patient′s clinical manifestations, biochemical indicators, and imaging examinations are necessary to diagnose PHPT qualitatively and location-specifically. In particular, it is necessary to pay attention to whether there is the possibilities of ectopic adenoma and multiple endocrine adenomas, to reduce the rates of missed diagnosis and recurrence.

OBJECTIVEAn unhealthy food consumption habit attributes to one of the etiology of gastro-esophageal reflux. The purpose of this article was to study the influence of food intake before going to bed on the nighttime gastro-esophageal reflux.

METHODSThirty-eight children with upper gastrointestinal symptoms were divided into two groups on the basis of taking (Group A, n=16) or not taking (Group B, n=22) food (non-stimulating) within 2 hrs before going to bed. All of them underwent 24 hr esophageal pH monitoring. The times of reflux episode, the longest duration of reflux, the times of reflux duration > 5 min, and the percentage of time of pH < 4 were compared between the two groups.

RESULTSThere were no significant differences in the parameters of pH monitoring between Groups A and B, with the times of reflux episode of 32 (21.5-43.5) vs 24 (15-37.3) , the longest duration of reflux of 6.6 (2.4-29.8) min vs 4.5 (2.5-13.2) min, the times of reflux episode longer than 5 min of 1.5 (0-3) vs 0 (0-3), and the percentage of time of pH < 4 of 4.3 (2.1-15.0)% vs 4.1 (2.0-7.2)% .

CONCLUSIONSNon-stimulating food intake before going to bed did not adversely affect the nighttime gastro-esophageal reflux.

Objective To explore the effect of " hospital informationized blood glucose management" on perioperative diabetic patients. Methods Three hundred patients with type 2 diabetes mellitus, who underwent selective operations from orthopedics, general surgery, urological surgery, and thoracic surgery were divided into two groups: 150 cases of blood glucose information management group and 150 cases of traditional blood glucose monitoring and management group. The blood glucose on target rate, percent of hypoglycemic events, percent of hyperglycemic events, the blood glucose level on the first postoperative day, the average hospitalization day, perioperative infection rate were evaluated for efficacy. Results The blood glucose on target rate in informationized blood glucose management group was significantly higher than that of the control group [(52.52 ± 18.31)%vs (14.88 ± 8.39)%, P＜0.01]. The frequency of hyperglycemia, the average daily blood glucose, the average blood glucose on fasting, after three meals and at night, the fasting and postprandial blood glucose level on the first postoperative day in informationized blood glucose management group were significantly lower than that of the control group [( 45. 31 ± 18.87)%vs (84.41±8.86)%, (8.59±1.34 vs 12.47±2.37) mmol/L, (7.33±1.41 vs 10.01±1.99)mmol/L, (8.89 ±2.34vs13.61±3.47)mmol/L,(9.47±1.94vs13.46±2.77)mmol/L,(9.40±2.72vs13.28±2.94)mmol/L, (8.28±2.11vs11.31±2.89)mmol/L,(8.29±2.51vs11.58±3.52)mmol/L,(8.25±3.67vs17.65±19.68) mmol/L, all P＜0.01]. In addition, the average hospitalization day of the informationized blood glucose management group was significantly shorter than that of the control group [(16±7 vs 21±15)d, P＜0.05]. The infection rate of the management group and the control group were 41. 2% and 58. 8% respectively. There was no significant difference between two groups (P＞0.05). Conclusion The " hospital informationized blood glucose management" is simple and practical, which may significantly improve the rate of blood glucose control in each period, reduce the average hospitalization day, and decrease perioperative infection tendency.

Objective To explore the relationship between hemoglobin (Hb) level during the first trimester of pregnancy and gestational diabetes mellitus (GDM). Methods A total of 1 276 participants, who underwent scheduled prenatal examination and normal singleton delivery at the Fifth People′s Hospital of Shanghai and Hospital of Intergrated Chinese and Western Medicine in Minhang District, from January 2016 to May 2018 were included. There were 99 cases of GDM (GDM group) and 1 177 cases of normal (control group) pregnant women.Based on the serum Hb level during the first trimester of pregnancy, participants were divided into three groups, 236 cases of low Hb level group (Hb<110 g/L), 868 cases of normal Hb level group (110 g/L≤Hb<130 g/L), and 172 cases of high Hb level group (Hb≥130 g/L). Maternal clinical data were collected, including Hb level during the first trimester of pregnancy, three-point blood glucose (BG) of oral glucose tolerance test (OGTT) and fasting insulin during the second trimester of pregnancy. Homeostasis model assessment of insulin resistance index (HOMA-IR) and homeostasis model assessment of pancreatic β cell function index (HOMA-β) were used to evaluate insulin resistance and pancreatic β cell function. Results (1) Hb level during the first trimester of pregnancy in GDM group was significantly higher than that in control group [(123±10),(119±11) g/L, P<0.05]. There were no significant difference in gravidity, parity, index of liver and renal function (all P>0.05). (2) Pre-pregnancy body mass index (BMI), 1-hour BG and 2-hour BG of OGTT were significantly increased in the high Hb level group during the first trimester of pregnancy, which were (23±4) kg/m2, (7.3±2.0) mmol/L, and (6.5±1.4) mmol/L (P<0.05), respectively. The pre-pregnancy BMI, 1-hour BG and 2-hour BG of the normal or low Hb level group were (22±3) kg/m2, (6.7±1.6) mmol/L, (6.1± 1.2) mmol/L; (22±3) kg/m2, (6.5±1.5) mmol/L, (5.9±1.1) mmol/L, respectively. There were no statistically significant difference in levels of fasting blood glucose, fasting insulin, HOMA-IR and HOMA-β within 3 groups (all P>0.05). (3) In the high Hb level group, prevalence of pregnancy overweight or obesity and GDM were the highest, which were 37.2%(64/172) and 15.1%(26/172), respectively; the differences were statistically significant (all P<0.05). (4) The serum Hb level in the first trimester was positively related with pre-pregnancy BMI (r=0.130, P<0.05), 1-hour BG (r=0.129, P<0.05), 2-hour BG (r=0.134, P<0.05), fasting insulin (r=0.096, P<0.05), and HOMA-IR (r=0.101, P<0.05).Logistic regression indicated that Hb≥130 g/L during the first trimester of pregnancy was an independent risk factor for GDM ( OR=2.799, 95% CI :1.186-6.604; P<0.05). Conclusion The high level of Hb (Hb≥130 g/L) during the first trimester of pregnancy is associated with GDM.

Objective To investigate the threshold values of insulin resistance ( IR) assessed by homeostasis model and the prevalence of IR in elderly people over 60 years old in Minhang district of Shanghai, and to evaluate the relationship between IR and metabolic syndrome ( MS) . Methods A total of 3003 elderly people aged 60 and over in the Jiangchuan community of Minhang District, Shanghai, were recruited, including 1286 males and 1717 females. Blood pressure, waist circumference, BMI, blood routine, serum creatinine, blood lipids, glucose, and fasting insulin were measured in all populations studied. Homeostasis model assessment ( HOMA) was used to estimate IR, and MS, and defined according to three diagnostic criteria including NCEP-ATPIII, IDF, and CDS. Results 75th percentile, 80th percentile and 90th percentile of HOMA values in 268 subjects with normotensive and normal BMI, glucose tolerance were considered as the thresholds of IR. The cut-off values were 2. 78, 3. 01 and 3. 56, respectively. And the prevalence of IR were 50. 0％, 42. 1％, and 27. 2％, respectively. IR level was significantly higher in people with MS. Based on the receiver operating characteristic ( ROC ) curve analysis, HOMA-IR and QUICKI index predicted MS well, and the optimal thresholds for diagnosing MS of HOMA-IR were 3. 17 for NCEP-ATPⅢ, 3. 02 for IDF and 3. 03 for CDS. BMI was the best factor for diagnosing IR among different MS components. Logistic regression analysis showed that gender, WC, BMI, SBP, HDL-C, TG, FBG and WBC were independent risk factors for IR. FBG≥5.84 mmol/L was the most dangerous factor of IR (OR=3.603,P<0.01), followed by WC≥85.4 cm(OR=2.152, P<0.01) and BMI≥24.6 kg/m2(OR=2.150,P<0.01). Conclusion The cut-off values of IR estimated by HOMA and the prevalence of IR were higher in elder subjects than other populations. IR was significantly positively correlated with MS. Excluding the conditions that insulin measurement were affected by external factors, HOMA-IR may predict the risk of MS. The components of MS were relative specific measurements of IR, FBG, BMI and WC were important risk predictors of IR in the elderly.

Objective:To Investigate comprehensive predictive ability of first-trimester complete blood count combined with maternal characteristics for gestational diabetes mellitus (GDM).Methods:From May 2015 to July 2018, 1 412 pregnant women were retrospectively screened at the Fifth People′s Hospital of Shanghai, Fudan University. We recruited 258 women who developed GDM and 1 154 women who had normal glucose level during pregnancy. At the first visit, clinical data and complete blood count result were obtained. GDM prediction models were established through logistic regression analysis of GDM related risk factors and the prediction abilities of each model were compared.Results:Logistic regression analyses identified age, pre-pregnancy body mass index, previous GDM history, family history of diabetes mellitus, the neutrophil-to-lymphocyte ratio, leukocyte, neutrophil, and monocyte counts were significantly independent predictors of GDM. In the entire cohort, the predictive ability of neutrophil and monocyte counts together with maternal basal characteristics model for the development of GDM [areas under the receiver operating characteristic curve (AUC-ROC)=0.809, integrated discrimination improvement (IDI)=0.056, P=0.001] was the best among various models (basal characteristics model, AUC-ROC=0.753; Monocyte count+ basal characteristics model, AUC-ROC=0.764; neutrophil count + basal characteristics model, AUC-ROC=0.775). Similar results obtained by the same way in all pregnant women without previous GDM history. Conclusion:It could improve the prediction of GDM with model incorporated maternal characteristics and first-trimester neutrophil and monocyte counts.

Objective:To investigate the effects of persistent isolated hypothyroxinemia in the first and second trimester of pregnancy on complications and adverse outcomes of pregnancy.Methods:A retrospective analysis was conducted in 784 pregnant women including 111 cases of persistent isolated hypothyroxinemia in the first and second trimester of pregnancy and 673 pregnant women with normal thyroid function as control group. All women were registered and delivered in the Department of Obstetrics of our hospital from April 2016 to April 2017. The complications and adverse outcomes of pregnancy in the two groups were analyzed.Results:Age, body weight before pregnancy, body mass index(BMI), 1 h plasma glucose and 2 h plasma glucose during oral glucose tolerance test in persistent isolated hypothyroxinemia group were higher than those in control group( P<0.05), with increased incidence of anemia during pregnancy( P<0.05). However, there were no significant differences in the incidences of gestational diabetes mellitus and gestational hypertension between the two groups( P>0.05). No significant statistical differences were found in macrosomia, stillbirth, neonatal malformation, postpartum hemorrhage, acute delivery, premature delivery, fetal intrauterine development delay, and small full-term infants between the two groups( P>0.05). Logistic regression analysis showed that age( OR=1.1, 95% CI 1.0-1.1, P=0.002) and pre-pregnancy body weight( OR=1.0, 95% CI 1.0-1.1, P=0.046) were risk factors for the occurrence of persistent isolated hypothyroxinemia in the first and second trimesters of pregnancy. Persistent isolated hypothyroxinemia in the first and second trimesters was associated with anemia during pregnancy( OR=1.9, 95% CI 1.1-3.2, P=0.024). Conclusions:Pregnant women who are older and heavier before pregnancy should pay more attention to their thyroid function. Pregnant women with persistent isolated hypothyroxinemia in the first and second trimesters should be concerned for anemia.
