Objective To explore frequency distribution of vitamin D receptor (VDR) genotype and the correlations between polymorphism of VDR gene Bsm Ⅰ sites and bone mineral density in the patients undergoing maintenance peritoneal dialysis.Methods A case-control study was conducted based on 82 patients with maintenance peritoneal dialysis and 80 healthy people.The frequency distribution of VDR genotype in two groups was detected and analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).Serum biochemistry and bone mineral density of the patients undergoing maintenance peritoneal dialysis were detected by dual energy X-ray absorption (DEXA) and automatic biochemical analyzer,respectively.All data was analyzed with SPSS 19.0 software.Results The frequency distribution of VDR genotype between case group and control group had no significant difference (P ＞ 0.05).The serum biochemical index such as Ca,P,alkaline phosphatase (ALP) and parathyroid hormone (PTH)] of patients with maintenance peritoneal dialysis had no significant difference among three VDR genotypes(P ＞0.05).Compared to VDR bb genotype,the serum Ca was significantly higher in VDR BB genotype (P ＜0.05).The bone mineral density (BMD) and T-Score of patients with VDR BB genotype were the lowest,the BB genotype was the highest,and the difference was statistically significant among three genotypes (P ＜0.05).Conclusions The frequency distribution of VDR genotype between case group and control group had no significant difference.However,there is a correlation between VDR gene BsmⅠ sites and bone mineral density of maintenance peritoneal dialysis patients.

Objective To explore the effect of N-acetylcysteine (NAC) on intercellular adhesion molecule-1(ICAM-1) expression and apoptosis in neonatal rats brain after hypoxic and ischemic brain damage (HIBD). Methods Ninety 7-day old SD rats were divided into sham operative group, HIBD group and NAC treatment group, each group containing 30 animals. ICAM-1 expression and the apoptotic rate of brain cells were measureed at 6h, 12h, 24h, 48h and 7days after model establishment by immunohistochemistry and TUNEL, respectively. Results Compared with sham operative group and NAC treatment group, the number of ICAM-1 expression cells and apoptotic cells in the brain tissue significantly increased in HIBD group. Conclusion NAC could inhibit ICAM-1 expression and cell apoptosis in the brain with HIBD, and had the preventive effect on hypoxic and ischemic brain damage in neonatal rats.

Objective To present a method for breast reconstruction with the deep inferior epigastric perforator (DIEP) flap and to summarize the operative experiences. Methods DIEP flaps were elevated without carrying rectus abdominis muscle. The breast was shaped after the deep inferior epigastric artery and vein were anastomosed to the internal mammary artery and vein. Results Since 2000, we have used the DIEP flaps in 15 cases of breast reconstruction. There were 100 % survival in 10 flaps, distal skin necrosis in 2 flaps, and a full loss in 2 flaps. With the follow-up of 6～12 months, the reconstructed breasts were well-shaped and there were no complications such as abdominal heria, bulge and weakness in donor sites. Conclusion DIEP flap is the development and refinement of TRAM flap and possesses of advantages such as rich blood supply, abundant tissue volume, minimal donor site morbidity and easy shaping. It is a new but reliable and safe technique for autologous breast reconstruction.

Objective To supply anatomic foundation for TRAM and DIEP flaps breast reconstruction with both sensory innervation and rectus abdominis muscle function preserved. Methods Dissections of T8～T12 nerves in anterior abdominal wall were performed on 9 embalmed female cadavers (18 sides). By reconstructing DIEP flaps in 15 cases, the natures of the intercostal nerves and the relations with deep inferior epigastric perforators were investigated. Results Most intercostal nerves pierced the rectus abdominis muscle in the lateral one third. There were interconnections between muscular branches of segmental nerves. Sensory branches traveling with vascular perforators were divided into medial branch and lateral branch. The mean length of pure sensory nerve was (27.6?12.2)mm. Conclusion It is possible to preserve sensory innervation by coapting lower intercostal nerves to the 4th thoracic nerve in TRAM and DIEP breast reconstruction. Sparing lateral one third of rectus abdominis muscle does not cause denervated atrophy in the rectus abdominis muscle after TRAM breast reconstruction.

Pulmonary arterial hypertension is common in patients with congenital heart disease.An effective reduction in pulmonary vascular resistance could improve the survival rate in the future.Research in the pathophysiology of pulmonary arterial hypertension shows that phosphodiesterase 5 inhibitors result in pulmonary vasodilation,decrease vascular resistance.Sildenafil,a inhibitor of phosphodiesterase 5 has been permitted to treat pulmonary arterial hypertension oversea now.Phosphodiesterase 5 inhibitors are proved to reduce pulmonary vascular resistance significantly,improve the survival rate in the future and be well tolerated.This review contains the changes of hemodynamics,exercise tolerance,side effect and pharmacokinetics of phosphodiesterase 5 inhibitors.

Objective To investigate the accuracy and reliability of the ABC/2 formula for measurement of intrace?rebral hematoma (ICH) volume by comparing it with software 3D-Slicer. Methods Computed tomographic image data of 184 patients with spontaneous ICH were collected. Hematoma volumes were estimated by using the ABC/2 formula and 3D-Slicer. Based on the volume calculated by 3D-Slicer, patients were further divided into three groups. Group 1 con?tained 55 patients with volume less than 30 ml, group 2 contained 68 patients with volume of 30-60 ml, and group 3 con?tained 61 patients with volume larger than 60 mL. Shape of the ICH was divided into regular (59 cases), irregular with frayed margins (107 cases) and multilobular (18 cases). Results of these two methods were compared according to hemato?ma size and shape. Results The estimated hematoma volume was (58.85 ± 37.38) mL in the ABC/2 formula and (50.08 ± 31.10) mL in 3D Slicer. The ABC/2 formula produced a mean overestimation of 8.77 mL and the mean percent deviation was 17.23%. The mean estimation errors were 2.90 mL (16.22%), 5.89 mL (13.55%), and 17.27 mL (18.76%) in groups 1, 2, and 3 when patients were grouped by hematoma size. The estimation errors were 3.46mL (8.76%), 7.99 mL (17.26%), and 30.81 mL (38.26%) in regular, irregular and multilobular hematomas when patients were grouped by shape. Conclusions The ABC/2 formula is a rough method for volume assessment of intracerebral hematoma and produc?es significant estimation errors. The size of estimation errors largely depends on hematoma shape.

Objective To explore a method for establishing the hamster model of Clostridium difficile-associated diarrhea (CDAD)and the indicators for its evaluation.Methods Clindamycin was administered to hamsters subcutaneously (day 1),and 24 h later infected with C.difficile clinical isolates KH1 (ribotype 027,106-108 CFU/mL)or SH9 (ribotype 001 ,108-1010 CFU/mL)by gavage.Animals were observed for CDAD symptoms such as diarrhea,weight loss and death.At the end of ob-servation period (day 7 or death),the cecum was collected from each animal for histological evaluation of inflammation.Results Following a single dose of 100 mg/kg clindamycin subcutaneously,all the animals challenged with KH1 (108 CFU/mL)devel-oped diarrhea and then died within 5 days.All the hamsters challenged with SH9 (1010 CFU/mL)developed diarrhea as well but only 66.7% died at the end of observation period.Among other groups,only one or none developed diarrhea and then died. The symptoms of hamsters with diarrhea included loose stool,wet tail and weight loss.On histological examination,conges-tion,hemorrhage and neutrophil infiltration of the mucosa were observed in the hamsters died of CDAD.Conclusions We have successfully established a hamster CDAD model that allows for future investigations.

Objective To study the clinical characteristics, diagnosis, treatment and prognosis of cancer metastasis to the thyroid gland. Methods A restropective review was performed on 35 patients with cancer metastasis to the thyroid gland in our hospital from 1958 to 2010. Diagnosis was confirmed by fineneedle aspiration cytology or histopathology in all cases. Results Primary tumor origin was identified in all but three cases. The lung was the most common primary tumor site( n = 16), followed by esophagus( n =9),breast ( n = 2), kidney ( n = 2), hypopharynx ( n= 1 ), nasopharynx ( n = 1 ) and soft palate ( n = 1 ). Thyroid metastasis was found before the diagnosis of the primary tumor was established in 12 cases; in the other 23 cases, the time lapse from diagnosis of the primary tumor to metastasis to the thyroid gland ranged from 0- 168 months, median 24 months. In 6 patients, this interval was more than 36 months. Fine-needle aspiration cytology ( FNAC ) confirmed metastatic malignancy in 7 patients, histology in 24, combined application confirmed the diagnosis in 4. After the metastasis to the thyroid gland was established, the median survival time for the entire group was 11.5 months, the 1-, 3- and 5-year survival rate was 43.8%,27. 8% and 11.9%, respectively. 28 patients were treated surgically, and 7 received nonsurgical therapy.The overall survival rate in the surgical group was higher than that in the nonsurgical group (P ＜0. 01 ). In those patients with metastatic cervical lymph nodes, median survival time did not vary from patients undergoing thyroidectomy with neck dissection to those undergoing thyroidectomy alone (P ＞ 0. 05 ).Conclusions Metastasis of carcinoma to the thyroid gland has an occult occurrence, thyroid metastases can be detected conclusively with FNAC. Metastasis to the thyroid gland implies advanced malignant tumors,often with poor prognosis.
