Objectives To investigate the mutational characteristics of MSX1 and PAX9 genes in a family affected by non-syndromic oligodonti so as to study the pathogenesis of oligodontia from a molecular prospective. Methods A family with oligodontia, but of different descent and unrelated healthy controls were enrolled in our study. Genomic DNA was isolated from the blood samples. Mutation analyses were performed by amplifying MSX1 and PAX9 exons and sequencing the products. Results DNA sequencing revealed a novel missense mutation c.348C>T in a highly conserved homeobox sequence of MSX1 and a known polymorphisms c. 469+35- c.469+45del in exon 1 and in intron in the two patients and in two unrelated healthy controls. But we did not detect any mutation in PAX9. Conclusion Our finding suggests the samesense mutation (c.348C>T) and the polymorphisms (c.469+35- c.469+45del) may be responsible for oligodontia phenotype in this Chinese family.

Objective To explore the influence of type 2 diabetes mellitus combined with subclinical hypothyroidism on diabetic vascular complications.Methods One hundred and two patients with type 2 diabetes mellitus were selected.The serum free triiodothyronine (FT3),free thyroxine (FT4),thyroid stimulating hormone (TSH),anti-thyroid peroxidase antibody (TPO-Ab),thyroglobulin antibody (TG-Ab) levels were measured by chemiluminescence method.The patients were divided into type 2 diabctes mellitus combined with subclinical hypothyroidism group (47 cases) and type 2 diabetes mellitus with normal thyroid function group (55 cases) according to the thyroid function.The glycated hemoglobin (HbA1c),total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),triacylglycerol (TG),high-density lipoprotein cholesterol (HDL-C),urea nitrogen,creatinine and albumin levels were measured.The estimated glomerular filtration rate (eGFR) was calculated according to the formula of modification of diet in renal disease (MDRD).The presence of diabetic retinopathy was examined by fundus examination,and the presence of lower limb artery lesions was measured by vascular ultrasound.All indicators were compared between 2 groups.Results There were no statistical differences in age,disease course,HbA1c,body mass index (BMI),TC,TG,HDL-C,LDL-C,incidence of lower limb artery lesions and incidence of diabetic retinopathy between 2 groups (P＞ 0.05).TheeGRF in type 2 diabetes mellitus combined with subclinical hypothyroidism group was significantly lower than that in type 2 diabetes mellitus with normal thyroid function group:(83.74 ± 21.55) ml/(min· 1.73 m2) vs.(115.02 ± 12.29) ml/(min· 1.73 m2),and there was statistical difference (t =4.274,P ＜ 0.01).The incidence of diabetic nephropathy in type 2 diabetes mellitus combined with subclinical hypothyroidism group was significanlty higher than that in type 2 diabetes mellitus with normal thyroid function group:48.9％ (23/47) vs.23.6％(13/55),and there was statistical difference (x2 =7.103,P＜ 0.01).Logistic regression analysis showed that subclinical hypothyroidism was a risk factor for diabetic nephropathy (OR =0.524,95％ CI 0.12-0.93,P ＜ 0.05),but it was not the risk factor for diabetic retinopathy (OR =0.618,95％ CI0.19-2.16,P =0.475) and lower limb artery lesions (OR =0.485,95％ CI 0.32-2.13,P =0.689).Conclusion Subclinical hypothyroidism in patients with type 2 diabetes mellitus has no obvious effect on lower limb arterial complications and diabetic retinopathy,but may increase the risk of diabetic nephropathy.

Objective To observe the sedative effectiveness of dexmedetomidine (DEX) in digital subtraction angiography (DSA),and to investigate the optimal and safe administration dose.Methods Seventy-five patients undergoing DSA were divided into three groups by random digits table with 25 cases each group.Three groups were treated with constant infusion of DEX by micro-pump 10 min before surgery with the same dose of saline.Then group A,B,C respectively were given 0.3,0.5,0.7 μg/ (kg·h) of the maintenance infusion rate,and stop infusion 10 min before the end of the surgery.At administration (T0),10 (T1),20 (T2) and 30 (T3) min after administration,10 min after surgery (T4),the heart rate (HR),mean arterial pressure (MAP),peripheral oxygen saturation (SpO2),Ramsay score,number of cases that appeared body movement were recorded,and their forgotten degree of operating memory were compared.Results The HR,MAP in three groups at T1-T3 was significandy lower than that at T0 (P＜ 0.05),T4 levels returned to T0 (P＞ 0.05).The HR,MAP in group C at T2,T3 was significantly lower than that in group A and group B at the same time (P ＜ 0.05).The Ramsay score in three groups at T2,T3 was significantly higher than that at T0(P ＜0.05),group B and group C at T2,T3 was significantly higher than that in group A at the same time (P ＜0.05).The SpO2 in three groups at each time point compared within and among groups was no significant difference (P ＞ 0.05).Group B and group C intraoperative involuntary movement in response patients were significantly less than in group A (5,3 cases vs.10 cases).Group A and group C surgery requires intervention patients was significantly more than in group B (8,10 cases vs.3 cases).Group B and group C amnesia grade Ⅲ rate was significantly higher than that in group A [64％ (16/25),72％ (18/25) vs.40％(10/25),P ＜ 0.05].Conclusion Infusion with 0.5 μ g/(kg· h) DEX 10 min after intravenous injection with 0.5 μ g/kg can get a better sedative effect,stable vital signs and less intraoperative adverse memory,and it can also improve patients' comfortable degree,which is safe and appropriate sedative dosage in DSA.

Objective To explore the efficacy and safety of low-dose ketamine for prevention of shivering during cesarean section under subarachnoid space and epidural anesthesia.Methods Ninety pregnant women who scheduled cesarean delivery under subarachnoid space and epidural anesthesia were randomized divided into three groups:control group (30 patients) low-dose ketamine group (30 patients) and high-dose ketamine group (30 patients).0.9％ sodium chloride,0.25 mg/kg(3 ml),and 0.50 mg/kg (3 ml) ketamine were given in three groups before operation.The incidence of shivering and adverse effect were recorded respectively before anesthesia,after anesthesia 15 min and 30 min and after operation 1 h.Results The level of mean arterial pressure (MAP) in control group after anesthesia 15 main and 30 min and after operation 1 h[(62 ± 10),(58 ± 8),(61 ± 11) mm Hg(1 mm Hg =0.133 kPa)] were significantly lower than those in high-dose ketamine group [(78 ± 12),(82 ± 8),(76 ± 11)mm Hg] and low-dose ketamine group [(72 ± 10),(76 ± 6),(80 ± 7) mm Hg],there was significant difference (P ＜ 0.05).There was no shivering need treat in low-dose ketamine group and high-dose ketamine group.The rate of hallucinations and nystagmus in low-dose ketamine group [0,6.7％ (2/30)] was significantly lower than that in high-dose ketamine group [20.0％ (6/30),50.0％ (15/30)],there was significant difference (P ＜ 0.05).Conclusion The pretreatment with low-dose ketamine on shivering during cesarean section under subarachnoid space and epidural anesthesia has better preventive effectiveness,0.25 mg/kg of ketamine is more effective than 0.50mg/kg.

Transcuataneous electrical nerve stimulation (TENS) analgesia as a non-drug method has received people's more and more attention recently. Considering problems of existing products, such as unstable performance and unsatisfied effectiveness, we developed a new analgesia therapy system for delivery based on bio-feedback TENS in our laboratory. We proposed a new idea for stimulation signal design, that is, we modulated a middle frequency signal by a traditional low frequency TENS wave in the new system. We designed different prescription waves for pain relief during a uterine contraction or massage between contractions. In the end, a bio-feedback TENS method was proposed, in which the waveforms of stimulation signals were selected and their parameters were modified automatically based on feedback from uterine pressure, etc. It was proved through quality tests and clinical trials that the system had good performance and satisfied analgesia effectiveness.
