Objective To investigate the relationship of thyroid hormones and serum lipid profile during Pregnancy. Methods 30 cases of healthy pregnant women were recruited in the study. The thyrotropin (TSH), free triiodothyronine (FT3), free thyroxine (FT4) and serum lipid profile were examined at 9 ~ 12, 14 ~ 17, 23 ~ 26 and 37 ~ 40 weeks of gestation and the correlations between them were analyzed. Results Positive correlation could be found between serum TSH and total cholesterol (CHOL), triglyceride (TRIG), low density lipoprotein cholesterol (LDL-C), ApolipoproteinA-I (APOA-I), ApolipoproteinB (APOB). Negative correlations could be found between serum FT3, FT4 and total cholesterol (CHOL), triglyceride (TRIG), low density lipoprotein cholesterol (LDL-C), ApolipoproteinA-I (APOA-I), ApolipoproteinB (APOB). And no correlation was found between serum thyroid hormones and high density lipoprotein cholesterol (HDL-C). Conclusion The thyroid hormones were closely related to serum lipid profile except of HDL-C.

Objective:To study the metabolism of high density lipoprotein cholesterol ( HDL-C ) and apolipoprotein A-Ⅰ( ApoA-Ⅰ) in different thyroid function status during pregnancy. Methods:This study re-cruited thirty cases of euthyroid, with nineteen cases of subclinical hypothyroid and eight cases of subclini-cal hyperthyroid pregnancy. The concentrations of fasting serum HDL-C and ApoA-Ⅰwere detected and ana-lyzed from 9-12, 14-17, 23-26, and 37-40 gestational weeks. Friedman repeated measures ANOVA on ranks was adopted to analyze the changes of serum HDL-C and ApoA-Ⅰat different stages. General line-ar model ( GLM) was adopted to analyze the differences of serum HDL-C and ApoA-Ⅰin different thyroid function status during pregnancy. Results:There were no significant differences of maternal serum HDL-C among different stages (χ2 =5. 428,P=0. 143,χ2 =2. 027,P=0. 567,χ2 =2. 885,P=0. 410). There were significant differences of serum ApoA-Ⅰduring euthyroid and subclinical hypothyroid pregnancies (χ2 =46. 343, P<0. 001,χ2 =35. 984, P<0. 001), and no significant difference during subclinical hyperthy-roid pregnancy (χ2 =6. 750, P=0. 080). There were significant differences of serum HDL-C and ApoA-Ⅰbetween euthyroid and subclinical hyperthyroid pregnancies (P=0. 025,P=0. 027), and no significant differences between euthyroid and subclinical hypothyroid pregnancies (P=0. 378,P=0. 549). Conclu-sion:Subclinical hyperthyroidism affected the metabolism of maternal serum HDL-C and ApoA-Ⅰ, which could affect the fetal growth and development. Subclinical hypothyroidism ( after treatment with drugs) had no obvious effect on the metabolism of maternal serum HDL-C and ApoA-Ⅰ.

[Objective]To study changes of ultrastructures and respiratory function of the spinal cord mitochondrial in experimental spinal cord injury.[Method]Forty-eight SCI models in adult SD rats were built based on modified Allen's method.Mitochondria was extracted from injuried spinal cord tissue by using modified Estabrook's method at 6h,12h and 24h after SCI.Then ultrastructural changes and respiratory function,including R3,R4,RCR,P/O were observed.[Result]Ultrastructure of mitochondria was damaged greatly.The results revealed that R3、RCR and P/O of injuried spinal cord mitochondria decreased significantly after injury compared to the normal control group(P

OBJECTIVETo analyze causes of missed diagnosis of hiding post-malleolar fractures in treating ankle joint fractures of pronation-external rotation type according to Lauge-Hansen classification and assess its medium-term outcomes.

METHODSAmong 103 patients with ankle joint fracture of pronation-external rotation type treated from March 2002 to June 2010,9 patients were missed diagnosis,including 6 males and 3 females,with a mean age of 35.2 years old (ranged, 18 to 55 years old) . Four patients were diagnosed during operation, 2 patients were diagnosed 2 or 3 days after first surgery and 3 patients came from other hospital. All the patients were treated remedially with lag screws and lock plates internal fixation. After operation,ankle joint function was evaluated according to American Orthopaedic Foot and Ankle Society (AOFAS).

RESULTSAll the 9 patients were followed up, and the duration ranged from 14 to 30 months (averaged, 17 months). No incision infection was found, and all incision healed at the first stage. At the latest follow-up, AOFAS was 83.0 +/- 4.4, the score of 4 patients diagnosed during operation was 85.0 +/- 2.9, and the score of 5 patients treated by secondary operation was 81.0 +/- 5.3. All the patients got fracture union observed by X-ray at a mean time of 2.2 months after operation. There were no complications such as internal fixation loosing, broken and vascular or nerve injuries.

CONCLUSIONAnkle joint fracture of pronation-external rotation type may be combined with hiding post-malleolar fractures. So to patients with ankle joint fracture of pronation-external rotation type, lateral X-ray should be read carefully, and if necessary, CT or MRI examination should be performed. If adding lateral X-ray examination after reduction of exterior and interior ankle joint fixation, the missed diagnosis may be avoided.

Objective To explore the changes in angiotensin Ⅱ(AngⅡ)produced by Langerhan islets of Syrian hamsters after blockage of renin-angiotensin system(RAS)by different inhibitors.Methods Islet cells from Syrian golden hamster were isolated and purified,and angiotensin Ⅰ was added.The experiment was then divided into six groups:control group(PBS was added),captopril group,chymostatin group,aprotinin group,?-antitrypsin group,and captopril+chymostatin group(according to inhibitors added).The content of AngⅡ in supernatant was detected by enzyme-linked immunosorbent assay(ELISA).Results Compared with control group,the AngⅡ content decreased by 42.50% and 50.94% in captopril group and chymostatin group,respectively(P

Objective To study the role of endoscopic retrograde cholangiopancreatography (ERCP) in diagnosing and treating iatrogenic bile duct injury after laparoscopic cholecystectomy (LC).Methods A retrospective study was conducted on 45 patients with iatrogenic bile duct injury after LC who were investigated and treated by ERCP from December 2002 to August 2015.Results Using the StrasbergBismuth classification,there were 14 patients with type A and 4 with type C who were managed successfully using endoscopic nasobiliary drainage (ENBD) and interventional ultrasound abdominal localized puncture and drainage ; 7 patients with type D were managed successfully using endoscopic sphincterotomy (EST) and endoscopic retrograde biliary drainage (ERBD).For the 5 patients with type E Ⅰ and 3 patients with type E Ⅱ who were treated by EST and ERBD,one patient who had common bile duct transection required cholangioenteric Roux-en-Y anastomosis.For the 6 patients with type E Ⅲ and 6 patients with type EⅣ who were treated by EST and ERBD,a patient required a cholangioenteric Roux-en-Y anastomosis to achieve good results.Conclusions When iatrogenic bile duct injury is suspected after LC,correct assessment with ERCP should be taken immediately.ERCP when combined with ENBD and (or) ERBD could reduce bile duct pressure and dilate stenotic bile ducts to avoid further operation.

BACKGROUND:Lumbar spinal stenosis is clinical repaired with decompression, bone fusion and internal fixation, and different internal fixation materials can be chosen during the surgery. OBJECTIVE:To explore the influence of polyetheretherketone (PEEK) pedicle screw fixation combined with interbody fusion on the bone fusion rate of patients with lumbar spinal stenosis. METHODS:A retrospective analysis was performed in 63 cases of lumbar spinal stenosis undergoing decompression and interbody fusion. These patients were divided into control group (titanium internal fixation system,n=31) and experimental group (PEEK pedicle internal fixation system,n=32) according the internal fixation materials folowed by posterior spinal decompression with interbody fusion. The Oswestry dysfunction index scores before and 4, 12, 24 weeks postoperatively and bone fusion rates at 4, 12, 24 weeks postoperatively were compared between the two groups. RESULTS AND CONCLUSION:Oswestry dysfunction index scores showed a gradual decline in both two groups before and 4, 12 and 24 weeks after treatment, but there was no difference at different time (P > 0.05). At 4 and 24 weeks after treatment, there was no difference in the bone fusion rates between the two groups (P > 0.05), but at 12 weeks after treatment, the bone fusion rate in the experimental group was better than that in the control group (P < 0.05). During the surgery, no infection and other adverse events occurred in the two groups. These results indicate that both PEEK and titanium internal fixation systems for lumbar tube stenosis have obtained good results, but PEEK material has a better role in the bone fusion at 4-12 weeks after internal fixation.
