Hereditary Severe Insulin-resistance Syndrome and Acanthosis Nigricans Caused by Novel Mutations in the INSR Gene.

Most cases associated with Hereditary Severe Insulin Resistance Syndrome (H-SIRS) are linked to mutations in the insulin receptor (INSR) gene. Patients with H-SIRS typically manifest symptoms of hyperinsulinemia, insulin resistance, and diabetes mellitus. Other symptoms include impaired glucose regulation, hyperandrogenism, and the presence of acanthosis nigricans (AN). In this report, we present two cases of H-SIRS in female children exhibiting various symptoms, such as hyperinsulinemia, fasting hypoglycemia, postprandial hyperglycemia, overweight, fatty liver, hyperandrogenism, and varying degrees of AN. One patient also presented with mental retardation. Gene sequencing identified specific mutations in the INSR gene for both patients: c.2663A > G (p.Tyr888Cys) and c.38_61del (p.Pro13_Ala20del). These mutations have the potential to disrupt the interaction between INSR and insulin, leading to abnormal insulin signaling, insulin resistance, and various clinical manifestations.

Research progress on the relationship between hypoglycemic drugs and sarcopenia / 中国临床药理学与治疗学

Sarcopenia is a disease characterized by a decrease in muscle mass and function that can induce adverse events such as falls, weakness, and death. The latest research shows that the use of many hypoglycemic drugs is associated with sarcopenia. Different types of hypoglycemic drugs may have different effects and mechanisms for the quality and function of skeletal muscle. In this paper, we review the research progress of the relationship between hypoglycemic drugs and sarcopenia and the molecular mechanism in recent years to provide a reference for the diagnosis and treatment prevention of sarcopenia in clinical areas.

Influencing factors of adult thyroid volume in Lanzhou City / 中华地方病学杂志

Objective:To investigate the thyroid volume of adults in Lanzhou City, and analyze its influencing factors.Methods:In June 2016, according to the principle of multi-stage stratified cluster sampling, Han residents aged 18 and above in Chengguan, Xigu and Qilihe districts of Lanzhou City who had lived there for more than 5 years were selected as research subjects, and a portable B-ultrasound machine was used for thyroid examination. Morning urine samples of the subjects were collected to test urinary iodine; fasting venous blood samples of the subjects were collected to test serum thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), anti-thyroglobulin antibody (TgAb), blood lipids [triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL)] and blood uric acid (Ua) levels. At the same time, body indexes systolic blood pressure (SP), diastolic blood pressure (DP), waist circumference, height and weight were measured, and the body mass index (BMI) was calculated. Multiple linear regression was used to analyze the influencing factors of thyroid volume.Results:A total of 1 009 subjects were included, aged (43.50 ± 15.16) years, and the thyroid volume was (8.74 ± 3.39) ml. Among them, 534 males had a thyroid volume of (9.46 ± 3.43) ml; 475 females had a thyroid volume of (7.93 ± 3.15) ml, the thyroid volume of males was larger than that of females ( t = 7.36, P < 0.01). Thyroid volume was positively correlated with age, height, weight, BMI, SP, waist circumference, LDL, Ua and TgAb ( r = 0.07, 0.23, 0.33, 0.27, 0.10, 0.27, 0.10, 0.08, 0.07, P < 0.05), and it was negatively correlated with thyroid nodules, TPOAb, TSH and urinary iodine ( r = - 0.16, - 0.07, - 0.10, - 0.08, P < 0.05). After multiple linear regression analysis, TSH, TPOAb, TgAb and thyroid nodules were included in the regression equation, and the standardized B values were - 0.135, - 0.065, 0.123 and - 0.197, respectively. Conclusions:The thyroid volume of males is larger than that of females in Lanzhou City. TSH, TPOAb, TgAb and thyroid nodules are influencing factors of thyroid volume.

Correlation Between Serum TSH Levels Within Normal Range and Serum Lipid Profile.

The aim of the work was to investigate the correlation between serum TSH (thyrotropin) levels within normal range and serum lipids. A total of 1962 subjects with normal thyroid function were enrolled. The subjects were divided into four groups according to the quartiles of serum normal TSH levels, [Q1 (0.27-1.68) mIU/l, Q2 (1.69-2.35) mIU/l, Q3 (2.36-3.07) mIU/l, and Q4 (3.08-4.20) mIU/l]. The effect of serum normal TSH levels on serum lipid profiles of different age or gender was analyzed. The total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) levels of the Q3 group and TG levels of the Q4 group were higher than those of the Q1 group in youth (p <0.05). The TC levels of the Q3 group were higher than those of the Q2 group in middle age (p <0.05). The LDL-C levels of middle age or elderly were higher than those of youth at the same TSH levels (p <0.05), while the TC levels of middle age were higher than those of youth in Q1, Q3, or Q4 group (p <0.05), and the TC and HDL-C levels of elderly were higher than those of youth in the Q2 group (p <0.05). The TG levels of the Q3 group were higher than those of Q1 group in males (p <0.05). The LDL-C levels of the Q3 group were higher than those of the Q1 group in females (p <0.05). In conclusion, the normal serum TSH levels were found to be closely related to serum lipid profiles, and with increasing TSH levels, serum lipids levels increased gradually.

Detection of thyroid nodules in people with abnormal lipid metabolism and related factors / 中华地方病学杂志

Objective:To investigate the detection rate and related factors of thyroid nodules in people with abnormal lipid metabolism.Methods:From September 4, 2016 to February 1, 2017, community residents living in Lanzhou City, Longnan City, Dingxi City and Linxia City of Gansu Province for more than 5 years were selected as the respondents. General data were recorded, venous blood was collected, blood lipid related biochemical indexes were detected, and thyroid ultrasound was performed. By comparing the general data and biochemical indexes, the detection of abnormal lipid metabolism and thyroid nodules were analyzed, and the risk factors of thyroid nodules in people with abnormal lipid metabolism were analyzed by logistic regression.Results:Two thousand and fifty-nine residents were included in this study (1 049 males and 1 010 females). The total detection rate of thyroid nodules was 23.17% (477/2 059). The detection rate of thyroid nodules in people with abnormal lipid metabolism [34.16%(151/442)] was significantly higher than that in people with normal lipid metabolism [20.16% (326/1 617) , P < 0.01], and the detection rate of thyroid nodules of women [43.37% (85/196) ] was higher than that of men [26.83% (66/246) , P < 0.01]. Among the people with abnormal lipid metabolism, the highest detection rate of thyroid nodules was in mixed hyperlipidemia [57.14% (16/28)], followed by hypertriglyceridemia [34.59% (92/266)]. The detection rates of thyroid nodules in the groups with elevated total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels [35.16% (32/91), 34.85% (23/66)] were higher than those in the marginal elevated group [27.04%(86/318), 30.42% (73/240)] and the normal groups [21.76% (359/1 650), 21.73% (381/1 753), P < 0.05]. The results of logistic regression analysis showed that the risk factors of thyroid nodules in people with abnormal lipid metabolism were increased age, elevated fasting blood glucose (FPG), elevated blood glucose 2 hours (2 h PG) after oral glucose tolerance test (OGTT) load and elevated glycosylated hemoglobin [HbA1c, odds ratio ( OR)=1.065, 1.387, 1.866, 1.384, P < 0.05]. Conclusions:The prevalence of TN is higher in populations with abnormal lipid metabolism. The control of blood sugar and blood lipid levels may play a role in the prevention of thyroid nodules.

Analysis on the related factors of obstructive sleep apnea hypopnea syndrome among the elderly in Changsha / 中国医师杂志

Objective:To explore the possible associated factors and parameters of obstructive sleep apnea hypopnea syndrome (OSAHS) among the elderly in Changsha.Methods:In the investigation of chronic diseases among the elderly in Changsha and the promotion and popularization of community standardized prevention and control, 500 elderly people >65 years old in Yuhua District of Changsha City were selected by multi-stage sampling method. Polysomnography (PSG) was used to detect sleep apnea hypopnea syndrome and collect physical examination indexes. A total of 70 cases met the diagnostic criteria of OSAHS apnea hypopnea index were divided into mild (42 cases), moderate (16 cases) and severe (12 cases). 20 cases of non OSAHS were selected as control group. The general information, PSG level and dynamic blood glucose level were compared between the two groups. Pearson correlation analysis was performed between ambulatory blood glucose level and sleep apnea hypopnea index in OSAHS patients.Results:There were significant differences in body mass index (BMI), girth ratio, smoking history, drinking history, apnea frequency, longest duration of hypoventilation, lowest oxygen saturation, supine apnea index and non supine apnea index between OSAHS group and control group ( P<0.05). The amplitude of blood glucose fluctuation was positively correlated with sleep apnea hypopnea index ( P<0.05). Conclusions:Among the many associated factors on OSAHS, BMI and the ratio of neck circumference to length and body position have the most notable influence. Patients with OSAHS are more prone to blood glucose fluctuations, and gradually worsen with the progression of OSAHS. Therefore, we should take targeted intervention measures.

Relationship between dietary phosphorus intake and nutritional status and calcium and phosphorus metabolism in patients with chronic kidney disease / 中华肾脏病杂志

Objective@#To evaluate the dietary phosphorus intake of non-dialysis patients with chronic kidney disease (CKD) 3-5 stage, and to explore the relationship between dietary phosphorus intake, nutritional status, and calcium and phosphorus metabolism.@*Methods@#A cross-sectional study was conducted. Non-dialysis patients of CKD 3-5 stage in Huashan Hospital outpatient clinic were selected. Three-day dietary diaries, anthropometric indicators, subjective global assessment (SGA) scores, blood and 24-hour urine biochemical indicators were collected. According to the median dietary phosphorus intake (873 mg/d), the patients were divided into high phosphorus intake group (≥ 873 mg/d) and low phosphorus intake group (<873 mg/d). The differences of characteristics, anthropometric indicators, SGA scores, blood and urine biochemical indicators between the two groups were compared. Multivariate linear regression analysis was used to analyze the correlation between dietary phosphorus intake and different kinds of food intake.@*Results@#A total of 118 patients were enrolled. The daily energy intake was (25.48±4.45) kcal/kg, protein intake was (0.88±0.22) g/kg and phosphorus intake was(862.85±233.02) mg/d. There were no significant differences in body mass index and SGA scores between high phosphorus intake group and low phosphorus intake group. The waist circumference, hip circumference, waist-hip ratio and leg circumference of male patients in high phosphorus intake group were higher than those in low phosphorus intake group (all P<0.05). There were no significant differences in anthropometric indicators between the two groups of female patients. The serum levels of intact parathyroid hormone (iPTH), sodium, triglyceride, blood RBC count, alanine aminotransferase, 24-hour urine urea nitrogen, 24-hour urine creatinine and 24-hour urine phosphate in the high phosphorus intake group were higher than those in the low phosphorus intake group (all P<0.05). Multivariate regression analysis showed that pork and chicken contributed the most to dietary phosphorus intake, followed by fish and dairy.@*Conclusions@#The daily dietary phosphorus intake of non-dialysis of CKD 3-5 stage patients is slightly higher than the recommended intake. The increase of dietary phosphorus intake may lead to the increase of serum iPTH and sodium levels. Proper control of dietary phosphorus intake will not impair the nutritional status of CKD patients.

Mechanism of Therapeutic Effect of Ligustrazine on Hepatic Veno-occlusive Disease Induced by Sedum aizoon in Mice / 胃肠病学

Background:Hepatic veno-occlusive disease( HVOD) is a disease characterized by hepatomegaly,jaundice, ascites,weight gain and lack of effective treatment currently. Our prophase research showed that ligustrazine had therapeutic effect on Sedum aizoon induced HVOD in mice. Aims:To investigate the mechanism of therapeutic effect of ligustrazine on Sedum aizoon induced HVOD in mice. Methods:A total of 115 mice were randomly divided into 4 groups:mice in group A were intragastrically administrated with 30 mg·kg-1 ·d-1 Sedum aizoon to induce HVOD and served as model group;mice in group B were given 30 mg·kg-1 ·d-1 Sedum aizoon + 100 mg·kg-1 ·d-1 ligustrazine and served as low dose ligustrazine intervention group;mice in group C were given 30 mg·kg-1 ·d-1 Sedum aizoon + 200 mg·kg-1 ·d-1 ligustrazine and served as high dose ligustrazine intervention group;mice in group D were given 30 mg·kg-1 ·d-1 PBS and served as normal control group. After 30 days,all the mice were sacrificed. HE staining and Masson staining were performed for histological examination. The mRNA and protein expressions of tissue factor(TF),nuclear factor(NF)-κBp65 and early growth response factor( Egr)-1 in liver tissue were determined by RT-PCR and Western blotting, respectively. Results:HE staining and Masson staining histological examination showed that ligustrazine could obviously ameliorate the pathological injury of liver tissue in HVOD mice. Compared with group D,the mRNA and protein expressions of TF,NF-κBp65,Egr-1 were significantly increased in group A( P 0. 05). Conclusions:Ligustrazine has therapeutic effect on HVOD,the possible mechanism is that ligustrazine could interrupt the activation of coagulation system by reducing the expression of TF via down regulating the expressions of NF-κBp65 and Egr-1,especially in high dose ligustrazine group.
