AIM: To evaluate the safety, efficacy and stability of posterior chamber phakic intraocular lens ( ICL ) implanation and clear lens extraction for the correction of high myopia.
METHODS: The study enrolled 56 cases ( 100 eyes ) of high myopia. Group I comprised 32 cases ( 58 eyes ) receiving ICL implantation and Group II comprised 24 cases (42 eyes) undergoing clear lens extraction. In this study, we evaluated the two groups of subject's the visual and refractive results, intraocular pressure ( IOP ) , endothelial cell density ( ECD ) , anterior chamber depth ( ACD) , lens transparency, the surgical complications as well as visual adverse symptoms before and after surgery.
RESULTS: The postoperative subjects in group I and group II were followed, uncorrected vision acuity ( UCVA)>0. 5 were 69. 0% in group I and 71. 4% in group II after 3mo. UCVA>0. 5 were 72. 4% in group I and 73. 8% in group II after 1a. Predictability of the manifest spherical equivalent refraction within±1. 00D was achieved in 62. 1%of eyes in group I and 57. 1% in group II after 1a. The central vault of the ICL ( distance from posterior surface of ICL to the crystalline lens ) measured with anterior segment optical coherence tomography ( AS-OCT ) was 0. 35-0. 54 (0. 40±0. 16) mm. Twelve point one percent of eyes in group I and 7. 1% of eyes in group II had transient mild increase in IOP. Here were statistically significant differences between preoperative and postoperative ECD (P<0. 001 ). Complications of surgery: 1 eye had ICL spontaneous rotation, 2 eyes had anterior subcapsular cataract, 4 eyes noticed halos around lights at night in group I. Three eyes had posterior capsule mild opacification, 3 eyes noticed halos around lights at night, 12 eyes had difficulty in near vision in group II.
CONCLUSION: ICL implantation and clear lens extraction are effective, safe and predictable surgical option for the management of high myopia. No severe complications occurred, but its long time effect and safety still need more time to prove.

OBJECTIVEAlthough primary ciliary dyskinesia (PCD) is a group of inherited diseases, accurate diagnosis and appropriate clinical care to prevent and treat the complications could maintain patients' quality of life and normal life span. The diagnosis of PCD may often be delayed because it is frequently misdiagnosed as bronchitis, sinusitis and otitis. This study aimed to analyze and summarize the clinical features of PCD and explore diagnostic and differential diagnostic procedures in children.

METHODSPatients were all chosen from the inpatient department of Beijing Children's Hospital, Capital Medical University between 1990 - 2006. The tunica mucosa bronchiorum and/or nasal mucous membrane were gained through bronchoscope in children suspected to have PCD. The ciliary ultrastructures were analyzed through the electron microscope. The clinical features and procedures of the diagnosis and differential diagnosis in children with PCD were analyzed.

RESULTSThere were totally 26 children diagnosed as PCD with 10 (38.5%) Kartagener syndrome. All Kartagener syndrome children had mirror image dextrocardia with normal cardiac structure and situs inversus viscerum. The bronchoscopy performed in eight of 10 Kartagener syndrome children showed bronchus transposition. Twenty-six children came from twenty-five families. Although the siblings of four probands also had the symptoms of chronic cough with sputum, running nose and recurrent respiratory infections, only a boy and his sister were diagnosed as Kartagener syndrome simultaneously. Their parents and the other family members were healthy. Of the 26 patients, 11 were boys and 15 were girls. The median age at diagnosis was 8.7 years. The age of onset was between the second day after delivery and fifteen years old, median age was 3 years. The course of disease before diagnosis was eleven days to twelve years (median 3.5 years). All the children had the symptom of cough, 24 of which had productive cough. Seven cases were found to have clubbing fingers. Dynein arm defect was found in 10 children, 6 of them had total absence of dynein arms and 4 had decreased dynein arm numbers. Microtube derangements were found in 8 children. One Kartagener syndrome child had a normal cilia structure. Bronchiectasis, consolidation and increased lung markings were found in 8, 6 and 7 patients separately on the radiographic study. Twenty patients had sinusitis. Nine of sixteen children had decreased PEF, FEV1 and/or FEF 25 - 75 on the pulmonary function test. Fifteen culture samples obtained from 6 children's sputum and/or bronchoalveolar lavage fluid were positive for 8 strains of Pseudomonas aeruginosa, 5 strains of Streptococcus pneumoniae and 2 strains of Candida albicans. In 1 subject more than one organism were found in the same sample. Hearing lost and gastroesophageal reflux were detected in 3 of 4 and 3 of 5 examined children respectively.

CONCLUSIONSThe onset of PCD can occur from neonate to adolescence and usually has a chronic course. The common symptom of pediatric PCD was productive cough and significant growth retardation. The most common ultrastructural abnormalities associated with PCD were the total absence of dynein arms, decreased dynein arm numbers and microtube derangement. Some patients have normal ciliary structures. Bronchiectasis, consolidation and sinusitis were usually seen on the radiography. Pseudomonas aeruginosa and Streptococcus pneumoniae were the two common bacterial organisms obtained from sputum and/or bronchoalveolar lavage fluid of PCD children. Some patients have mixed infections. PCD children have high percentages of hearing lost and gastroesophageal reflux.

OBJECTIVETo investigate the relationship between respiratory diseases onset and the meteorological factors in the same period and in a specific environment. METHODS METHODS: By using the data of daily incidence of respiratory diseases obtained from Dongzhimen Hospital Affiliated to Beijing University of Chinese Medicine from January 1, 1998 to December 31, 2007, and the data of 16 items of meteorological factors (such as the average, maximum, and minimum temperatures, etc., including meteorological factors derived) obtained from the Beijing Municipal Meteorological Observatory, mathematical statistical methods were applied to achieve the non-linear correlation analysis, or the correlation test, between the incidence of respiratory diseases and the time-related meteorological factors.

RESULTSThe simple correlation coefficients of the relationship between the incidence of respiratory diseases and 9 meteorological elements, including the average values of temperature, maximum temperature, minimum temperature, degree of comfort, precipitation, vapor pressure, low cloud cover, change of vapor pressure, and change of wind speed, were all greater than 0.8286, in which one of the relationship between the incidence of respiratory diseases and the maximum temperature is as high as 0.9670. Statistical tests showed R>Rα=0.05 and F>Fα=0.05.

CONCLUSIONSThe incidence of respiratory diseases was closely correlated to meteorological factors, such as air temperature, vapor pressure, precipitation, wind speed, etc. To a certain extent, this conclusion confirmed the scientificity and objectivity of the theory of five evolutive phases and six climatic factors (Wu Yun Liu Qi ) in Huang Di Nei Jing (The Yellow Emperor's Canon of Internal Medicine).

OBJECTIVETo summarize clinical and molecular features of two children with autosomal recessive chronic granulomatous disease caused by CYBA mutations.

METHODThe clinical records and CYBA mutations were reviewed for analysis of infections and inflammatory complications.

RESULTThe first case was a girl diagnosed with "liver and spleen abscess" in our hospital when she was 2.9 years old, with past history of neonatal impetigo and recurrent purulent lymphadenitis and positive family history. The results of DHR123 flow-cytometry showed that positive phagocytes after phorbol ester (PMA) stimulation was 84.63%. CYBA mutation analysis showed that she had heterozygous 35C > T, Q3X and IVS-2A > G. The second case was a boy diagnosed with "sepsis (salmonella D)" when he was 4 years old with a past history of impetigo, sepsis, perianal abscess, skin infection and positive family history. The results of flow cytometry showed that positive phagocytes after PMA stimulation was 96.13%. CYBA mutation analysis showed that he had homozygous 35C > T, Q3X and his parents were all carriers. All of them had BCG related axillary lymphnode calcification.

CONCLUSIONA22CGD cases had recurrent purulent infections (skin, lymphnode, liver and spleen, lung, blood), DHR123 flow cytometric analysis helped the diagnosis of CGD, CYBA mutation analysis ascertained the diagnosis of A22CGD.

OBJECTIVETo study the newborn's Apgar score in 'one minute' and relevant factors.

METHODSOne year inpatient woman from a Maternal and Child Health Hospital of Anhui province were selected by cluster sampling method and newborn asphyxia situation was investigated using Apgar score and self-designed questionnaire.

RESULTSThe Apgar score in 'one minute' which marking 8 to 10, 4 to 7 and 0 to 3 were found in 1875 (73.78%), 426 (16.77%) and 240 infants (9.45%) respectively. The average Apgar score in 'one minute' and five minutes were (7.69 +/- 2.27) and (9.01 +/- 1.89) respectively, The Apgar score in 'one minute' was significantly correlated with that of five minutes (Pearson coefficient correlation r = 0.841, P = 0.00). Ordinal regression analysis revealed that parturient age (OR = 1.04), being farmer (OR = 2.22), parity (OR = 1.26), assistant vaginal delivery (OR = 4.93), caesarean section (OR = 1.95), pregnancy-induced hypertension syndrome (OR = 1.42), albuminuria in gestational period (OR = 1.44), newborn being male (OR = 1.23), low birth weight (OR = 2.94), inborn abnormality (OR = 12.12), premature birth (OR = 1.22) and complications of delivery (OR = 5.04) were risk factors while the number of years under study (OR = 0.91), prenatal check-up (OR = 0.48), body length of newborn infant (OR = 0.88) and single birth (OR = 0.57) were protective factors.

CONCLUSIONApgar score in 'one minute' of newborn infant was affected by several factors as stated above. Health care program in earlier period toward community parturient should be strengthened in order to discover and control high risk factors of duration of pregnancy in earlier period.

OBJECTIVE: To localize the gene of autosomal dominant familial dilated cardiomyopathy with conduction defect. METHODS: A Chinese family which was diagnosed as dilated cardiomyopathy with conduction defect was studied. Venous blood (3 - 5 mL) from some family members was collected, and genomic DNA was extracted from the blood. Then whole genome wide scan was performed after excluding the known markers on the candidate loci (CMD1A, CMD1 E, CMD1F, and CMD1H) by two-point linkage analysis. RESULTS: No significant evidence for linkage was found in the two point linkage analyses to the known markers in the analyzed family. And the whole genome wide scan showed the maximum LOD score reached 2.68 at marker D3S1614 ( at recombination fraction theta = 0). CONCLUSION The related gene in this kindred is located on 3q26 other than on CMD1A, CMD1H, CMD1E, and CMD1F.

BACKGROUNDEfficient cell adhesion and proliferation is a central issue in cell-based tissue engineering, which offers great promise for repair of urethral defects or strictures. This study evaluated the adhesion and growth of rabbit uroepithelium on a surface-modified three-dimensional poly-L-lactic acid (PLLA) scaffold.

METHODSUrethral mucosa were harvested from male New Zealand rabbits and the urothelium were dissociated and then cultured. Immunocytochemistry on cultured uroepithelium for pancytokeratin and uroplakin II and TE-7 confirmed pure populations. After in vitro proliferation, cells were seeded onto a surface-modified urethral scaffold with non-knitted filaments. The morphology and viability of the cells were examined by immunohistochemical and fluorescence staining. Inverted and scanning microscopes were used to document cell growth and adhesion.

RESULTSThree to five days after primary culture, the uroepithelial cells gradually became confluent, assuming a cobblestone pattern. The filaments of the urethral scaffold had excellent biocompatibility and allowed growth of the uroepithelium, without affecting viability. The uroepithelial cells adhered to and grew well on the scaffold. After 3 - 7 days, the cells grew vigorously and meshes of the scaffold were full of uroepitheliums.

CONCLUSIONSThe surface-modified urethral scaffold with non-knitted filaments allows the growth of uroepithelium and can serve as a carrier for the tissue engineering of urethra.
