Objective To report the clinical results of the treatment for recurrent immunologic disorders of cornea and conjunctiva by conjunctival resection with amniotic membrane transplantation(AMT). Design A retrospective clinical case series. Participants Five patients 5 eyes with recurrent immunologic disorders of cornea and conjunctiva were enrolled into this study, including 2 eyes of phlytenular keratoconjunctivitis with corneal lesion, 1 eye of nodular episcleritis, 2 eyes of corneoscleral interstitial keratitis. Methods Patients were treated with partial conjunctiva resection and AMT. After operation, steroids and cyclosporin eye-drops were given for 2-3 weeks, and patients were followed up for 6-12 months. Main Outcome Measures Complications and recurrent situations were observed. Results The corneal disease kept quiescent, and the blood vessel subsidized. There were no recurrences during the follow up period in 4 cases. Recurrent signs were noted in one patient at 12 months after surgery. But no recurrence of corneal lesion was noted although the conjunctivitis was severe. Conclusion Local conjunctiva resection combined with AMT is a useful method for recurrent cases of immunologic disorders of cornea and conjunctiva. (Ophthalmol CHN, 2006,15:177-179)

In recent years, a large number of studies have found that central lymph node metastasis of the papillary thyroid microcarcinoma (PTMC) is significantly related with some risk factors.These high risk factors include age below 45 years old, BRAF gene mutation, vascular epithelial growth factor-C high expression, tumor diameter≥5 mm, multifocal and bilateral tumor, thyroid capsule invasion and so on.These high risk factors involve in disease process, and interact with each other.The studies of the high risk factors can help us to predict the risk of central lymph node metastasis in the patients with PTMC, thus to effectively guide the patients' treatment.

Objective To know the masons of delaying to receive medical treatment among patients with breast cancer, and then reference to related health education. Methods 13 patients with breast cancer were selected in this research, interviewed them by phenomenological method to know their reasons of delaying to receive medical treatment, analized the results of interview by Clolaizzi method. Results The were five themes for patients with breast cancer about delaying to receive medical treatment, they were not understand breast cancer-related knowledge, shortage of method of self-examination, psychological factors, working pressure and family factors, social environment factors. Conclusions We should strengthen breast cancer-related health education when changed women's traditional ideas and ameliorated their family and social environment.

A reusable chronocoulometric adenosine triphosphate (ATP)-aptamer sensor was developed in this work.A short chain of DNA marked as cDNA containing complementary sequence was immobilized on gold electrode based on Au-S self-assembly.The ATP aptamer was hybridized with cDNA.The surface-confined DNA could bind with [Ru(NH3)63+ (RuHex) in the electrolyte via electrostatic interaction.Upon target ATP binding, the aptamer confined onto electrode surface was disassociated from the cDNA oligonucleotides into the solution.Such surface density change of DNA lead to the decrease of chronocoulometric signal for the RuHex which confined on the electrode surface.The chronocoulometric signals showed a linear relationship with logrithm of ATP concentration in the range of 1 nmol/L to 100 μmol/L, and the detection limit of this aptamer sensor could reach 0.5 nmol/L (S/N=3).This aptamer sensor could be regenerated 5 times by simple steps.With this aptamer sensor, the basal level of ATP in the brain cortex micorodialysate was determined to be 19.2±3.7 nmol/L (n=3).

Objective To explore the related structures of retrosigmoid approach by microanatomy and virtual anatomy and provide a reliable approach with more morphologic data. Methods Twenty sides of 10 adult cadaveric heads were dissected to simulate retrosigmoid approach under the microscope. The neurovascular structures of pontocerebellar trigone were observed, and the related structures were simultaneously measured based on the junction of superior petrosal sinus and sigmoid sinus and internal acoustic pore. The internal auditory canal was opened by drilling the margin of the internal auditory meatus and its structures were watched. With the help of Dexotroscope system, the data of five patients' CT and MRI were applied to reconstruct and anatomize the structure of retrosigmoid approach. Results It was found that the distance from the junction of superior petrosal sinus and sigmoid sinus to the trigeminal nerve was (38.50±2.64)mm, to the acoustic-facial bundle (27.80±2.25)mm, to the glossopharyngeal nerve (32.70±2.11)mm, to the hypoglossal nerve (44.30±2.05)mm, and the distance from internal acoustic pore to the trigeminal nerve was (5.68±1.55)mm, to the abducent nerve (13.80±1.81)mm, to the tentorium of cerebellum (5.00±0.66)mm, to the glossopharyngeal nerve (6.34±1.24)mm. The pontocerebellar trigone was divided into the anterior compartment, the middle compartment, the posterior compartment built on the acoustic-facial bundle and the glossopharyngeal nerve. Their structures were displayed after drilling the margin of the internal auditory meatus. Dexotroscope system clearly displayed asterion, the angle of transverse and sigmoid sinus, jugular foramen, internal acoustic pore, basilar artery and its branches, and theirs spatial relationship.Conclusion The three compartments of the pontocerebellar trigone are helpful to understand the feature of the neurovascular layer, the measurement is favorable to quantize the relation of the related structures and to judge the space of each compartment. Recognizing the anatomical marker of internal acoustic pore can support preservation of the inner structures. Virtual anatomy of Dexotroscope system can display local anatomical structure respectively. Both microanatomy and virtual anatomy have their advantages and disadvantages respectively and integration can be beneficial to understand neurovascular structures in the pontocerebellar trigone.

Objective To discuss the relationship between leptin level and polycystic ovary syndrome (PCOS) in adolescent patients with polycystic ovary syndrome, and to explore the classification diagnosis method of adolescent PCOS and indicator for clinical monitoring of obese patients. Methods All enrolled adolescent individuals were assigned into four groups: 30 normal adolescent individuals in the control group, 30 simple adolescent obese individuals in the simple obesity group,27 obese adolescent PCOS patients in the obese PCOS group and 14 nonobese adolescent PCOS patients in the nonobese PCOS group. The fasting serum samples were prepared for leptin level measurement and analysis, Results The serum leptin level of in the control group, the simple obesity group, the obese PCOS group and the nonobese PCOS group were ( 19.44 ± 6. 63 ) μg/L vs.(23.09 ±7. 39) μg/L, (42. 99 ±9. 83) μg/L and (31, 92 ±7, 02) μg/L,respectively. Leptin in the obese PCOS group was significantly higher than that in the control group and the simple obese group (t = 2. 903 and 2. 714 respectively,Ps ＜ 0. 05 ). Conclusion Monitoring the serum level of leptin can not only aid the classification of adolescent PCOS patients and guide the treatment, but also can serve as a indicator for therapeutic monitoring of obese adolescent PCOS.
