OBJECTIVETo evaluate the virological response of managing chronic hepatitis C (CHC) with peg-interferon alpha-2b (PEG-IFN alpha-2b) and ribavirin.
METHODSWe retrospectively analyzed the virological response of 40 patients with different genotypes of hepatitis C virus (HCV) infection after anti-HCV management. Patients were given different dosages of PEG-IFN alpha-2b and ribavirin based on their weights. The duration of treatment was 48 weeks for patients infected by HCV genotype 1, and was 24 weeks for the others. HCV RNA was tested before treatment, 12 weeks post management, end of treatment, and 24 weeks after treatment stopped.
RESULTSData from 40 patients were collected. Among them, 24 cases experienced HCV genotype 1 infection, and 16 cases were infected with other genotypes. Between these two groups, the early virological responses were 75.0% (18/24) and 87.5% (14/16), the end-of-treatment virological responses were 80.0% (16/20) and 85.7% (12/14), and the sustained virological responses were 56.2% (9/16) and 78.5% (11/14), respectively.
CONCLUSIONBody weight-based customized PEG-IFN alpha-2b in combination with ribavirin can effectively treat patients with different genotypes of CHC.

It is now clear that continued stimulation o f the neurohormonal system in heart failure (HF) has serious deleterious effects on the heart. The increase of circulating catecholamines exerts direct toxic ef fect on cardiac myocytes, increases membrane permeability and myocardial fibrosi s; lead to aggravation of HF. β-blockers are commonly used in the treatment of HF including propranolol, metoprolol, bisoprolol, bucindolol and carvedilol. These drugs are used in combination with ACEIs, digitalis and diuretics. Genera lly, the benefits of β-blockade therapy in HF include improving symptoms, decr easing morbidity, mortality, elevating need for hospitalization and quality of l ife. β- blockade therapy arrests and reverts LV remodeling and improves the ri sk of life threatening arrhythmias and sudden cardiac death. A few serious adver se effects include hypotension, heart blocks, bradycardia and fluid retention.

OBJECTIVETo detect changes of Foxp3 expression in the decidua in patients with preeclampsia and investigate the correlation of Foxp3-924 (rs2232365) polymorphisms with preeclampsia.
METHODSFrom October 2011 to December 2012, 252 normal pregnant women and 156 preeclampsia patients of Han nationality from the same geographic region were tested for Foxp3-924 genotypes by polymerase chain reaction with sequence-specific primer (PCR-SSP). Sixty-eight of the patients with preeclampsia (33 with mild and 35 with severe preeclampsia) and 30 of the normal pregnant women were also examined for Foxp3 expression in the decidua using immunohistochemical method.
RESULTSFoxp3 positive expression rates in the decidua was 51.52% in mild preeclampsia and 28.57% in severe preeclampsia cases, significantly lower than that in the control group (86.67%, P<0.05). In preeclampsia patients, the frequencies of Foxp3-924G/G, G/A, and A/A genotypes were 0.1346, 0.4615 and 0.4038, respectively, and the frequencies of Foxp3-924A and Foxp3-924 G were 0.6346 and 0.3654, respectively. The genotype frequencies of Foxp3-924G/G, G/A and A/A in the control group were 0.1508, 0.4087 and 0.4405, respectively, and the frequencies of Foxp3-924 A and Foxp3-924 G were 0.6448 and 0.3552, respectively. No significant differences were found in the gene frequencies of Foxp3-924G/A between preeclampsia patients and the control group (P>0.05).
CONCLUSIONThe expression level of Foxp3 in the placental tissue of preeclampsia patients is significantly lower than that in normal pregnant women, suggesting that lowered Foxp3 expression decreases the immunosuppressive function and causes imbalance of immune tolerance between maternal-fetal to induce preeclampsia. Foxp3-924 polymorphisms is not significantly correlated with the occurrence of preeclampsia.

OBJECTIVETo investigate the clinical application of free forearm flap in the functional hemitongue reconstruction.
METHODSFrom July 2002 to November 2006, 40 patients with tongue cancer underwent hemiglossectomy and primary hemitongue reconstruction with free forearm flaps. In some cases, the lateral antebrachial cutaneous nerves of the flaps were anastomosed with the lingual nerve to restore the flap sensation.
RESULTSAll patients recovered uneventfully after surgery with no morbidity in the donor site. All free flaps survived. The average follow-up period was 2 years and 6 months. The aesthetic and functional results were both satisfactory. The swallowing and speech function were almost normal. The flap sensation was partially restored.
CONCLUSIONSGood functional hemitongue reconstruction can be achieved with free forearm flaps.

OBJECTIVETo investigate the value of microsurgical reconstruction of the tongue after hemiglossectomy with lateral arm free flaps in the treatment of tongue cancer.
METHODSFrom October 2006 to April 2007, ten patients underwent simultaneous reconstruction of the tongue and oral floor defects with lateral arm free flaps after resection of squamous cell carcinoma of tongue in our hospital. The flaps ranged from 8 cm x 5 cm to 9 cm x 6 cm in size, and were adjusted to the defect of the tongue. The vascular pedicle included the posterior radial collateral artery and the accompanying veins. The outcome of reconstruction was evaluated by follow-up examinations, including the contour and mobility of the reconstructed tongue, the swallowing function and the speech function.
RESULTSAll patients recovered uneventfully from surgery, without any major postoperative complications. The transplanted flaps survived. During follow-up period the contour of the reconstructed tongues was satisfactory. The patients demonstrated good functional mobility of the reconstructed and remaining tongue. Postoperatively, the swallowing and speech function was nearly at normal levels and the patients could ingest a solid or semisolid diet.
CONCLUSIONSMicrovascular reconstruction of the tongue with lateral arm free flaps after hemiglossectomy is an ideal and safe method, but long term results need to be further studied.

OBJECTIVETo explore the operation indication and safety of presacral tumor.
METHODSClinical data of 36 patients with presacral tumor from November 1990 to May 2006 treated in our hospital, in whom 23 patients underwent trans-sacral operation, were analyzed retrospectively.
RESULTSThe operation time was from 43 to 210 min (average 94 min). The volume of blood loss was from 30 to 2000 ml (average 350 ml). Hospital stay was from 8 to 16 days (average 10.7 days). There were 13 different pathology types of tumors in the 36 patients including 26.4% of malignancy. Complications of trans-sacral operation included 1 case of ureteral damage, 1 case of sacral wound hernia, 1 case of presacral abscess who was healed by sigmoid stoma and wound drainage.
CONCLUSIONTrans-sacral resection of low presacral tumor is safe and effective with less trauma, less bleeding and quick recovery.

Replication of duck plague virus(DPV) in artificially infected ducks were detected by in situ hybridization (ISH) which employed a 37bp oligonucleotide as probe designed according to DPV DNA sequence in GenBank. The results indicated that DPV DNA was detected in liver, intestine and bursa Fabricius at 4 h, in spleen and esophagus at 6h, in thymus at 12h post infection; DPV DNA in lung and kidney was detected only in dead ducks and no positive signal was detected in muscle, heart, cerebrum and pancreas. DPV DNA was distributed in cell nucleus and cytoplasm. Hepatocytes, sinus endodermal cells and Kuffer's cells were the mainly infected cell types in liver. DPV DNA was mainly detected in epithelium of villi, in lamina propria of intestinal villi of duodenum, in stratum spinosum of esophagus, and in epithelium, cortex, medulla of bursa Fabricius. The positive signals were mainly detected in medulla of thymus, lymphocytes and macrophages of spleen. The research suggests that ISH is a direct and specific method in detecting DPV DNA in paraffin sections and it's also a good method for virus diagnosis and DNA location of DPV.
