BACKGROUND:Hyaluronan with special linear macromolecular structure and rheologic property has good biocompatibility and becomes a signal matter of the cel surface, which possesses a promising application potential in tissue-engineering field. OBJECTIVE:To review the research progress in medical hyaluronan composites. METHODS:Related literatures concerning preparation, safety evaluation and clinical trials of hyaluronan composites were extensively reviewed and comprehensively analyzed in the three folowing aspects: cartilage scaffold, cornea scaffold and submucous bulking agent. RESULTS AND CONCLUSION:The hyaluronan composite has a potential use in cartilage scaffold and cornea scaffold as its suitable porosity and pore size, biomimetic three-dimensional microstructure, excelent physical and chemical property and biological property. The hyaluronan composite as a bulking agent has been applied clinicaly, and results from some clinical trials have shown that the composite used as bulking agent has the problems about low efficacy and complications, which need to do further improvement. More researches are needed in product design, evaluation of performance and safety for expending and optimizing the clinical applications of the hyaluronan composite.

Idiopathic hypogonadotropic hypogonadism (IHH) is characterized by delayed or absent puberty and lowered sexual function as a result of impaired pulsatile gonadotropin-realeasing hormone (GnRH) secretion.Identification of TAC3/TACR3 mutations as the culprits of IHH revealed that neurokinin B (NKB) signaling pathway was involved in the regulation of pulsatile GnRH secretion.This review focuses on the involvement of NKB signaling in pulsatile GnRH release,the discovery of TAC3/TACR3 mutations and the phenotypes,and treatment of patients who carry TAC3 or/and TACR3 mutations.

Objective To evaluate the efficacy of oral etopside (VP16) and oral cyclophosphamide (CPM) combination in the treatment of hormone-refractory prostate cancer (HRPC). Methods Between June 2000 and July 2003,9 patients with HRPC were treated with oral etopside (50 mg/d) and oral cyclophosphamide (100 mg/d) for 21 days with every 28 days as a cycle.Inclusion criteria were previous complete androgen blockade,anti-androgen (flutamide) withdrawal evaluation,and clinical or biochemical disease progression.The therapy was continued until there was evidence of disease progression or the patients could not tolerate the adverse effects of the medications. Results All the 9 patients had a mean follow-up of 7.5 months.PSA levels decreased by at least 50%,from pre-treatment of (90.5?43.6)ng/ml to post-treatment of (24.8?22.2)ng/ml,in 4 patients. The mean duration of response was 6.8 months (range,2-15 months).An objective response was obtained in 2 patients (1 of CR and 1 of PR).Toxic and adverse effects were minimal. Conclusions The combination of oral VP16 and CPM may be an efficacious and well-tolerated regimen in patients with HRPC.

50% for more than 1 month as effective,and the efficacy for soft tissue metastases were classified as complete,partial remission,stabilization and progression.Results All patients were followed up for 6-24 months(mean,12 months) with the evaluation of efficacy and toxicity.PSA levels decreased by at least 50% in 6 of 12 cases(50%);it decreased from(63.9?47.3)ng/ml before treatment to(14.4?8.8)ng/ml after treatment,with a mean duration of response being 7.5 months(range,5-12 months).Partial remission of soft tissue metastases was obtained in 2 cases;the metastatic lesions were reduced from 4.0 cm?5.0 cm,(3.0cm?)(3.5) cm to 2.0 cm?2.0 cm,1.0 cm?1.5 cm,respectively,by the treatment,with response duration being 3 and 8 months,respectively.Toxicities were minimal with leukopenia at grade Ⅰ in 1 case,anemia at grade Ⅰ in 1,baldness at grade Ⅰ in 1,nausea at grade Ⅰ in 2 and impaired liver function at grade Ⅱ in 1.Conclusions The combination of oral estramustine phosphate and oral etoposide may be an effective and well-tolerated regimen in patients with HRPC.

[Summary] Patients with infertility and non-obese polycystic ovary syndrome ( PCOS) were treated with continuous subcutaneous pulse infusion of GnRH. After the treatment, a 32-year old female had regular menstrual cramps. Dominant follicle occurred after 2 months of treatment. The patient was pregnant and now has a healthy baby boy. It shows that the pulse infusion of GnRH could induce spontaneous ovulation and natural fertilization of the patients with non-obese PCOS.

Objective To investigate the value of magnetic resonance (MR) diffusion weighted imaging(DWI) in the diagnosis of prostate cancer(PCa). Methods Fifty-seven patients with suspected prostate cancer underwent DWI and T_2-weighted imaging (T_2W). These images and apparent diffusion coefficient (ADC) maps results were compared with histopathologic findings. Receiver operating characteristic(ROC) analysis was used to compare the cancer detection performance of them. The results were rated on a scale of scores Ⅰ (benign) to Ⅴ (malignant) on the basis of ADC maps. Abnormal voxels were overlaid on the corresponding transverse TRUS images and used to perform voxel-guided biopsy. Results DWI had a sensitivity of 85%, specificity of 82%, positive predictive value of 80%, negative predictive value of 86% , and accuracy of 83%. T2WI had a sensitivity of 77%, specificity of 71%, positive predictive value of 69%, negative predictive value of 79%, and accuracy of 74%. The areas under the ROC curves for DWI and T_2WI were 0. 830 and 0. 742, respectively. The performance of DWI in PCa detection was significantly better than of T_2WI (P<0. 05). 6 of 30 patients with negative DWI results also had negative biopsy findings. PCa was detected in 17(85%) of 24 men findings with voxel score Ⅳ , with a sensitivity of 100%, specificity of 46%, positive predictive value of 71 %, negative predictive value of 100% , and accuracy of 77%. Conclusions The performance of DWI in PCa detection was better than of T_2 WI. ADC maps can be transferred to TRUS images and used to sample regions of cancer in men with rising PSA levels and negative findings at prior biopsy with good accuracy. DWI appears to be a robust and reliable method to examine the whole prostate within an acceptable scan time in clinical settings.

OBJECTIVE To study the causes of recurrence and treatment methods in patients with recurrent sinonasal melanoma. METHODS From 1993 to 2003, a retrospective analysis of consecutive 11 cases with recurrent sinonasal melanoma was conducted. RESULTS Four out of the 11 cases with recurrent sinonasal melanoma were caused by misdiagnosis, while the other 7 cases recurred after operation with pathological diagnosis. Among the 7 cases, 5 were found recurrences after operation alone, and the other 2 after the operation and radiation therapy. The recurrence lesions located in nasal and paranasal sinus in 7 cases, in orbit, skull base, soft and hard palate in 1 case, in parotid gland and skin in 1 case. In face, orbit and extended skull base in 1 case. Cervical lymph node recurrence developed in 1 patient. The time of first relapse was 10 months after therapy. The 1-, 2-and 3-year survival rates after reoperation were 72.7 %, 18.2 % and 9.1 % respectively. CONCLUSION The reasonable treatment and decrease the misdignosis are the main measures to improve the cure rate of recurrent sinonasal melanoma.
