?As a globally recognized irreversible blindness disease, glaucoma can lead to pathological intraocular hypertension, loss of optic ganglion cells and axonal progressive, more and more deep optic cup, and the expanded visual field defect. Various researches show that excitatory amino acid toxicity, oxidative damage, apoptosis, intracellular Ca2+overloading etc. , pathogenic factors are all involved in the occurrence and development of glaucoma. Now, a variety of clinical drugs and operation treatment are applied to control the glaucoma progress. Further more, there are many new drugs and methods in the process of development. This is an article on the current anti-glaucoma drugs.

Objective To compare the effect of different puncture positions in the combined spinal epidural anesthesia (CSEA)in cesarean section.Methods Ninety uterogestation women under-going elective Caesarean section were randomly divided into two groups,45 in each group.L3-4 inter-vertebral space was selected as puncture point.Group R kept right lateral position for two minutes af-ter puncture and turned 30°left tilt supine position until ready for surgery.Group L was turned to su-pine position after left lateral punctured and then turned to 30 left tilt supine position until ready for surgery.1% ropivacaine 1.5 ml+ 10% glucose 0.5 ml was used for spinal anesthesia.The sensory block level and adverse reaction within 1 5 min after the spinal anesthesia were observed,and the neo-natal Apgar score and the pH value of umbilical artery blood were recorded.Results The final block level of the group R was significantly lower than group L,and the time achieving final block height was significantly shorter than that in group L(P <0.05 ).The ephedrine dosage of group R 0 (0-6) mg was significantly lower than that of group L6 (0-12)mg (P <0.05).The PH value of umbilical artery blood in group R was significantly higher than that in group L (P <0.05).There was no sig-nificant difference in neonatal Apgar score.Conclusion In Cesarean section,keeping right lateral puncture position for two minutes after infusion and then turning 30° left tilt supine position can a-chieve better effects than 30°left tilt supine position immediately after puncturing.

Objective:China was categorized as one of the 68 countdown countries to achieve the United Nations Millennium Development Goals (MDG) 5. This paper aimed to analyze the situation of maternal survival, and coverage of proven cost effective interventions in China, where specific attention was paid to disparities. Methods: National maternal and child mortality surveillance data were used to estimate maternal mortality ratio (MMR). Coverage for proven interventions was analyzed based on National Health Services Survey, where experts' consultations were made for complementation. Results: There had been a significant reduction of MMR in China, however great disparities existed, with rural Ⅱ to Ⅳ areas experiencing 2 to 5 times higher maternal mortality risks than urban areas and accounting for over 70% maternal mortality burdens. Postpartum hemorrhage, pregnancy associated hypertension, embolism and sepsis were the leading causes, and over 75% of the maternal mortality was caused by preventable or curable causes. Maternal health services utilization decreased in accordance with region' s development level. Socioeconomic factors like financial difficulties were the main obstacles hindering access of care.Even those who made deliveries in hospitals faced different probabilities in receiving qualified care according to their socioeconomic standings. Conclusion: China is on track to achieve MDG 5, however great disparities exist. It is necessary to specifically target rural types Ⅱ to Ⅳ areas. Major causes of maternal mortality which can be prevented or averted through the provision of essential obstetrical care. Yet as compared with maternity health needs, insufficient coverage of maternal and child health (MCH) care services and poor service quality are the leading predisposing factors contributing to maternal mortality in China.

The morbidity of diabetes has been increasing rapidly in recent years. Delayed wound healing has become a common complication in diabetes, which seriously affects the orthobiosis of patients. Exploring and finding the molecular mechanisms of diabetic wound healing and the effective therapies to promote wound healing have important clinical significances. Stem cells transplant has become a research hotspot in accelerating diabetic wound healing. This article reviewed the present approaches concerning stem cells transplant in diabetic wound healing both at domestic and abroad, and looked forward the clinical therapy of stem cells on diabetic wound healing.

Objective To study normal flora components of conjunctiva, explore the relationship between normal flora and ocu- lar bacterial infections.Methods The data of 1 198 bacterial cultures of conjunctiva in non-infectious cataract patients were re- viewed and compared with the results of 985 specimens of conjunctivitis, keratitis and endophthalmitis from January 2000 to December 2004.Results Positive culture of conjunctiva in non-infectious cataract patients was 628 in 1 198 specimens (52.4%).These bacteria including gram-positive cocci and gram-neganve bacilli constituted the normal flora of conjunctiva. Staphylococcus epidermidis was the predominant bacteria (51.1%, 341/667) and its prevalence increased during this 5-year period.S.epidermidis and S.aureus were also the most frequently isolated pathogens in specimens of conjunctivitis, keratitis and endophthalmitis.The correlation was statistically significant between the positive rate in normal eye and conjunctivitis or keratitis in terms of these two species, but not statistically significant between normal eye and endophthalmitis.The resistance rate of normal flora of conjunctiva to ampicillin, amikacin, tobramycin, ciprofloxacin, and ofloxacin increased year by year. The resistance rate to gentamicin and the combination of two drugs decreased.The changing resistant pattern was similar in pa- tients with eye infection.Conclusions There is a close relationship between the normal flora S.aureus and S.epidermidis of conjunctiva and the bacterial infection of ocular surface, but no significant correlation between normal flora and the pathogen of endophthalmitis.

Objective To investigate the clinical significance of thyroglobulin antibody (ATG) and thyroid peroxidase antibody (ATPO) in patients with vitiligo. Methods Venous blood samples were obtained from 87 patients with vitiligo and 90 age- and sex-matched normal human controls. Chemiluminescence was applied to measure the serum levels of ATG, ATPO, free triiodothyronine, free tetraiodothyronine and thyroid stimulating hormone (TSH). Results There was a significant increase in the positivity rates of ATG (23.0% vs 6.7%, P < 0.01) and ATPO (24.1% vs 7.8%, P < 0.01) as well as the serum level of TSH (3.4 ± 2.4 vs 2.4 ± 1.2 pmol/L, P < 0.05) in the patients with vitiligo compared with the normal human controls. It is worth mentioning that all patients positive for ATG or ATPO were diagnosed with vitiligo vulgaris. The positivity rates of ATG and ATPO in patients with vitiligo aged from 11 to 20 years and 21 to 40 years were significantly higher than those in age-matched normal controls (all P < 0.05). Also, female patients had a higher positivity rate of ATG and ATPO than female controls did (34.1% vs 8.5%, χ2 = 8.90, P < 0.01; 34.1% vs 10.6%,χ2 = 7.29, P < 0.05). The highest positivity rates of both ATG and ATPO were 53.3%, which were observed in vitiligo patients aged from 11 to 20 years, followed by patients from 21 to 40 years (ATG 34.5%, ATPO 34.5%). In patients with vitiligo positive for both ATG and ATPO, the occurrence of autoimmune thyroid disease was 70% (14/20), significantly higher than that in ATG- and ATPO- positive healthy controls (16.7%, χ2 = 5.4, P < 0.05). Conclusions ATG and ATPO were observed in young female patients with vitiligo vulgaris, and they may be associated with the development of autoimmune thyroid diseases.
