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.

Objective To analyse the characterisitics of daily blood glucose profiles of insulinoma using continuous glucose monitoring system(CGMS) and to investigate the value of CGMS in the diagnosis of insulinoma. Methods The blood glucose of 6 patients with pathologically-confirmed insulinoma(insulinoma group) were detected by CGMS for 3 consecutive days.The mean blood glucose(MBG),M-value of Schlichtkrull(M-value),frequency distribution of glucose levels and the hypoglycemic episodes of CGMS were measured,and the results were compared with those of normal glucose regulation(n=6,control group) and patients with newly-diagnosed type 2 diabetes with reactive hypoglycemia(n=5,diabetes group). Results The M-value of insulinoma group was significantly higher than that of control group(P0.05).The M-value and MBG of diabetes group were higher than those of insulinoma group and control group(P

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.

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.

Objective To evaluate the pathophysiological change of diabetes and its significance in the treatment of newly-diagnosed type 2 diabetic patients.Methods A total of 322 newly-diagnosed type 2 diabetic patients were included in this study and were divided into 2 groups with normal or impaired islet first-phase insulin secretion according to arginine stimulation test.The former group was assigned to repaglinide (Novo Norm), rosiglitazone (Avandia) and mefformin subgroups and the latter one to repaglinide,rosiglitazone and glipizide subgroups randomly.Results (1)Compared with baseline,fasting plasma glucose,2 h postprandial plasma glucose and HbA_(1C) were significantly decreased in all subgroups after 3 and 6 months of treatment (all P

Objective To evaluate the effect of an integrated control strategy and to quantify the spatial-temporal variation of infected snails in the bottomland areas after the strategy was implemented.Methods Based on the geographic database of infected snail distribution at the village level during 2004-2010 in Anxiang county,Hunan province,spatial autocorrelation analysis and spatial scan statistics were applied to analyze the spatial-temporal characteristics on the distribution of infected snails.Results The number of embankments with infected snails in Anxiang county decreased from 23 in 2004 to 10 in 2010,while the rate of frame with infected snail in embankments decreased from 4.32‰ in 2004 to 0.12‰ in 2010.The spatial distribution of infected snails was nonrandom,only in 2004 and 2005 with Moran's I=0.21 (P＜0.10) and Moran's I=0.13 (P＜0.10) respectively.Data from the local spatial auto-correlation analysis showed that the number of villages with H-H types of auto-correlation model had been gradually decreasing.The results of SaTScan statistics appeared the same as from the local spatial auto-correlation analysis,showing that the number of areas with increased risk was decreasing.Conclusion The comprehensive measures with emphasis on infectious source control seemed effective for schistosomiasis control program.The current distribution characteristics provided us with evidence that the resource assignment could be more reasonably implemented so as to control schistosomiasis in a more effective way.

OBJECTIVETo evaluate the therapeutic effect of retained copper wires combined with pingyangmycin (PYM) injection for complicated cavernous venous malformation.

METHODSThe location of venous malformation was detected by physical examination and MRI. The copper wires in 0.2 mm width were used to puncture the lesion repeatedly and retained in the lesion to form a net. After that, 8 mg PYM was injected into the residue malformed veins. 8-10 days later, the copper wires were taken out and necrotic tissue was squeezed out. The wounds of punctual holes healed through dressing. The patients received postoperative MRI to evaluate the therapeutic effect.

RESULTSFrom Jan. 2002 to Dec. 2008, 45 cases were treated. The patients were followed up for 1-3 years. 51.1% (23/45) of the lesions shrinked markedly or even disappeared. 42.2% (19/45) of the lesions reduced. 6.67% (3/45) of the lesions didn't change. There was no complication like invasive infection.

CONCLUSIONSIt is very effective to treat complicated cavernous venous malformation with retained copper wires combined with pingyangmycin injection.
