Objective To discuss the effect of blood glucose monitoring during pregnancy and pregnancy outcome in patients with gestational diabetes mellitus (GDM). Methods One hundred and fifty-three GDM patients from July 2007 to July 2008 were analysed.The cases were divided into satisfactory group (74 cases)and unsatisfactory group (79 cases) based on the level of bleod glucose and compared the pregnancy outcome between the two groups. Results The incidences of pre-eclampsia, polyhydramnios, macrosomia, neonatal hypoglycemia, hyperbilirubinemia of satisfactory group were lower than those of unsatisfactory group(5.41% vs 17.72%,4.05% vs 20.25%, 12.16% vs 31.65% , 5.41% vs 20.25%,8.11% vs 30.38%). The difference is statistically significant (P <0.05). The incidence of premature rupture of membranes, premature birth, postpartum hemorrhage, fetal distress of satisfactory group were lower than those of unsatisfactory group, but there was no significant difference between the two groups. Conclusion GDM can cause great harm to maternal and child health, and satisfactory blood glucose control during pregnancy may reduce maternal and child complications.

Objective To investigate the results and related key points in operative treatment of talar body fractures. Methods From April 2002 to July 2008, 44 patients with talar body fractures underwent the operation. There were 3 females and 41 males. The mean age of the patients was 31.7 years. The fractures occurred on the left side in 26 patients and on the right side in 18 patients. According to Sneppen classification, 24 type Ⅱ, 20 type V. Eleave cases were open fractures, according to the Gustilo-Anderson classification, there were 3 cases in type Ⅰ , 7 in type Ⅱ, 1 type in Ⅲ A. The mean interval between injury and surgical treatment for open fractures and close fractures was 5.3 hours and 8.9 days. The mechanism of injury was a fall from the height in 18 patients, a traffic accident in 13 patients, a crush injury in 8 patients, a sprain injury in 4 patients and a cut injury in 1 patient. Anteromedial approach was used for 15 close fractures, anterolateral approach for 3 and combined anteromedial-anterolateral approach for 15. K-wires fixation were utilized for 3 fractures, screws and temporary K-wires fixation for 5 cases, bioabsorbable screws for 2fractures, cannulated screws for 30 fractures and cannulated screws and threaded cancellous screws for 4cases. Results Thirty-five patients were followed up 21 to 89 months (average, 44.5 months). Necrosis of incision was found in 4 cases, wound infection occurred in 1 case. All fractures had achieved bone union;the average healing time was 22 weeks. Functional results were assessed according to AOFAS score, the average score was 77.3, There were 11 patients in excellent results, 13 in good, 10 in fair and 1 in poor. The overall excellent and good rate was 68.6%. Avascular necrosis occurred in 5 cases. Traumatic arthritis occurred in 19 cases. Arthrodesis was needed in 5 cases. Conclusion The timing and approach of surgery is determined by the condition of the talar fractures and soft tissue. Anatomical reduction, preservation of the blood supply and early active pain-free mobilization are key points in the treatment of the talar body fractures.

Objective To explore a new method for one-stage repair of the intestinal leakage based on the principle of magnetic compression anastomosis. Methods Twenty-four dogs were randomly divided into experimental group (n = 12) and control group (n = 12) according to random number table. The model of upper and multiple intestinal leakages was established by making transverse incisions of 1 cm in length on the jejunum wall about 50 cm and 100 cm away from the Treitz ligament. Forty-eight hours later, two NdFeB magnetic rings with the magnetic flux of 2500 G were put into the intestine from the leak sites. The leak sites were pressed between the two rings. The ventages in the control group were sutured. The condition of the dogs was observed after the repair of the leakage. The excreting time was recorded, and the leakage pressures of the anastomotic stoma were detected.The positions of the magnetic rings in the experimental group were detected by X ray. Tissues of the anastomotic stoma were processed by hematoxylin eosin and Masson staining. All data were analyzed using the two-sample t test. Results Severe abdominal infection occurred 48 hours after the establishment of the model. All the intestinal leakages in the experimental group were successfully repaired and the dogs survived for a long time. The magnetic rings were excreted six or seven days after the repair. Eight dogs of the control group survived. The leakage pressure of the anastomotic stoma seven days after the repair was (134 ±23)mm Hg (1 mm Hg =0. 133 kPa) in the experimental group and (91 ± 18)mm Hg in the control group, respectively, with a significant difference between the two groups (t = 3.225, P ＜ 0.05). The leakage pressure of the anastomotic stoma 14 days after the repair was (281 ±7)mm Hg in the experimental group and (271 ±21) mm Hg in the control group, respectively, with no significant difference between the two groups (t =0. 988, P ＞ 0.05). Histological observation showed that after the magnetic compression anastomosis, the intestinal muscle and mucosa recovered well, inflammatory reaction was slight and less collagen fiber and scar was formed. Conclusions Application of magnetic ring with the magnetic flux of 2500 G in one-stage repair of the intestinal leakage in the state of severe abdominal infection is safe and reliable.

OBJECTIVETo investigate elastic changes of the radial artery, a medium-sized muscular peripheral conduit artery, in patients with borderline systolic hypertension.

METHODSUsing a non-invasive high-resolution echo-tracking device coupled to a photoplethysmography (Finapres system) allowing simultaneous arterial diameter and finger blood pressure monitoring, we measured radial artery elastic parameters of 20 patients with borderline systolic hypertension and 20 normal subjects according to Langewouters model.

RESULTSThe diameter of the radial artery of control subjects and those with borderline systolic hypertension at the isobaric level of 100 mmHg and mean arterial pressure was similar, but the compliance and distensibility at similar conditions in patients with borderline systolic hypertension did not further reduced and even increased.

CONCLUSIONIn patients with borderline systolic hypertension, the adaptive responses of the radial artery compliance and distensibility to increased pressure were directed to maintain its elasticity, contributing to the homeostasis of the cardiovascular system.

OBJECTIVETo probe the clinical and pathological characteristics of nodular lymphocyte predominant Hodgkin lymphoma (NLPHL).

METHODSThe pathologically confirmed 14 cases of NLPHL patients (since January 2001 to December 2012) were collected from Tianjin Medical University Cancer Hospital. The laboratory examinations' results, clinical manifestations, short-term and long-term outcomes of these cases were analyzed in this study.

RESULTSThe immunohistochemistry of all cases showed CD20 (+)/weak (+) and CD30 (-), most of them CD15 (-). The morbidity of NLPHL during the same period of Hodgkin's lymphoma (HL) was around 6.3%. The median age was 38 (13-54) years old, 92.9% of the patients sought medical advice according to self-feeling of superficial lymph nodes. All patients' disease progressed slowly and the sizes of lymph nodes were within 3 cm. Of the 14 patients, 7 patients were treated with chemotherapy and 7 patients chemoradiotherapy. The treatment results showed CR+CRu rate as 85.7% and ORR 100.0%. The rates of 5-year event-free survival (EFS) and overall survival (OS) were 85.7% and 100.0% respectively. Short and long term efficacies between chemotherapy and chemoradiotherapy had no significant differences. Meanwhile, varieties chemotherapy regimens showed no significant effects on short- and long-term efficacies (P>0.05).

CONCLUSIONThe pathologically confirmed 14 cases of NLPHL had the classical and tumorous maxi cell, which showed CD20 (+)/weak (+) and CD30 (-), very few cases showed weak CD15 (+). The incidence of NLPHL was low. The majority of the NLPHL patients were middle-aged and youth. Moreover, the better short- and long-term outcomes over classical HL ones were observed regardless of patients' stage.
