Objective To evaluate the efficacy of the coated metallic stent insertion in patients with complexity esophageal stricture and(or) fistula caused by carcinoma. Metheds 51 cases with complexity esophageal stricture and (or) fistula caused by carcinoma had undergone the treatment in our hospital. Different methods were used with different patients.Patients were evaluated for symptomatic dysphagia improvement 1-month and 12-month after treament. Results It were succeeded in placement of stents in all cases. All of them nearly complete symptomatic dysphagia relief or significant improvement .The diameter of the stricture increased from(4.05?1.34) mm to (13.03?3.99) mm (P

The first case of Hurthle cell tumor of the thyroid gland(HCT) was described in the literature a century ago. Since then, researches of HCT have been progressing from cellular to molecular level. We reviewed the literatures about HCT researching, with emphasis on differentiated diagnosis of benign and malignant HCT.

Objective: To separate and determine two constituents of Danshensu and protocatechuic aldehyde in compound Danshen Dropping Pill. Methods: The chromatographic conditions were as follow: Nucleosil C18 column, a mixture of methanol-water-acetic acid glacial (19∶80∶1) as the mobile phase with a flow rate of 1 mL per minute and the detection wavelength at 279 nm. P-hydroxybenoic acid was used as internal standard. Results: The calibration curves were linear in the range of 10～80 mg/L (r=0.9995) for Danshensu and 2～16 mg/L (r=0.9996) for protocatechuic aldehyde . The average recovery of Danshensu and protocatechuic aldehyde were 99.4 %and 99.5 %respectively. Conclusion: This method is accurate, simple and convenient, rapid and reproducible and can be used for the quality control of compound Danshen Pill.

Objective To study the interaction of tetramethylpyrazine and human serum albumin(HSA).Methods The fluorescent quenching of HSA with te tramethylpyrazine has been detecte d by fluorimetry.Results It was found that fluo-rescence of HSA were quenched by tetr amethylpyrazine.The fluorescent q uenching data were analyzed accordi ng to Stern -volmer equation and the bindi ng constant was obtained.Conclusion The mechanism of fluorescent quench ing is considered to be the formation of HSA-tetramethylpyrazine complex.

Objective To evaluate early and mid-term results in infants,weighing less than 2 500 g,who underwent early cardiac surgery on cardiopulmonary bypass (CPB).Method Since November 2003 to December 2007,28 consecutive infants of less than 2 500 g underwent early cardiac surgery on CPB in Children's Hospital Affiliated to Fudan University.Sixteen infants were male,and 12 infants were female.The mean pregnancy period was 34 weeks (30 to 41 weeks) ,and 14 patients were premature,and the mean birth weight was 2 010 g(1 370-2 500 g).Mean age at operation was 27.46 d (range 1～61 d),and mean weight was 2 391 g (range 1 500～2 500 g).Deep hypothermia circulatory arrest was used in 9.Indications for surgery were:ventricular septal defect (10 infants),transposition of great arteries (6 iofants),totally anomalous pulmonary venom return (5 infants),pulmonary atresia with intact ventricular septum(2 infants),coarctation of aorta (1 infants) ,interrupted aortic arch (1 infants),cortriatriatum(1 infants),abnormal original of fight pulmonary artery (1 infants).Resuits Two (7.14%) infants died after operation at early phase.Mean duration of mechanical ventilation and intensive care unit stay were 113.9 h and 14.4 d,respectively.During follow-up (mean 16.87 months),one died.Two patients needed reintervention.About 84.4% infants didn' t need reintervention at the end of 12-month followup.Conclusions If medicine is aseless,infants woth low birth weight and congenital heart defect can obtain satisfactory outcome after CPB.Perioperative proration for virtual organs should be payed attention to.

The basic pain threshold and pain tolerance were measured by use of radiant heat stimulation in healthy volunteers, which were close to normal distribution. The stability was obtained by repeated determination for same individuals in different time. With this method, a clinical assessment of analgesic drugs was carried out among healthy volunteers. Acetaminophen-Codeine tablet ( 2 tablets ) was able to depress pain response by increasing pain threshold and tolerance of 23% and 12% ( P

Buprenorphine, a synthetic derivative of Thebaine, is a strong new analgesic agent. It was compared with pethidine in doudle-blind trial of 86 burn and plastic patients with severe or moderate pain. The result showed that the analgesic effect of Buprenorphine 0.3 mg I. M. appeared superior to Pethidine 50mg ( P

Diffusion tensor imaging is a non-invasive MRI technique which can identify changes of cerebral microstructure that CT and MRI is difficult to find, especially in the change of nerve fibers direction, which can be used for the researches of evaluation, recovery mechanism and prognosis of neurology. It has been applied in rehabilitation of motor, language and recognition of post-stroke patients.

Objective To examine the interrelations among vascular calcification, bone denaity,osteoprotegerin (OPG) and soluble receptor activator of NF-kB ligand (sRANKL) in maintenance hemodialysis (MHD) patients. Methods The levels of serum OPG and sRANKL from 39 MHD patients were measured by ELISA. The vascular calcification was detected by plain radiographs. Bone mineral density (BMD) was measured with dual-energy X-ray absorptionmeter.Interrelations among above parameters were examined statistically. Results (1) Among 39 MHD patients, 25 cases were identified as vascular calcification by radiographic film. The proportion of patients with mild vascular calcification was 41.0% (16 cases), moderate and severe vascular calcification was 23.1% (9 cases). Compared to patients with mild vascular calcification,serum OPG level [(342.50±171.53) ng/L vs (206.21±137.88) ng/L,t=-2.253, P=0.0251 and OPG/sRANKL ratio (454.65±455.63 vs 135.31±136.81, t=59, P=0.035)were significantly higher in patients with moderate and severe vascular calcification,while serum sRANKL level [(0.10±0.08) pmol/L vs (0.12±0.08) pmol/L, t=0.534, P>0.05] was not significantly different. Multiple linear regression analysis showed that OPG/sRANKL ratio was independent factor of vascular calcification score. (2)Compared to patients with normal bone volume, the patients with abnormal bone volume had higher serum OPG level [(249.05±137.66) ng/L vs (226.67±170.12) ng/L], lowerserum sRANKL level [(0.11±0.08) pmol/L vs (0.12±0.02) pmol/L], and higher OPG/sRANKL ratio(202.31±219.24 vs 148.08±210.10), but these parameters were not significantly different betweenthese two groups. Multiple linear regression analysis showed that OPG/sRANKL ratio was anindependent factor of T score of lumbar vertebra. (3)Muhiple linear regression analysis revealed that vascular calcification score was an independent factor of T score of lumbar vertebra and hip.Conclusions Vascular calcification score is an independent factor of BMD of lumbar vertebra and hip in MHD patients. Serum OPG/sRANKL ratio may play an important role in the association between vascular calcification and BMD in MHD patients.
