AIM: To analyze the electronic product use time, writing time, playing piano time and outdoor activity time and the distribution of myopia in 586 cases of school age children in our hospital. ·METHODS: A retrospective analysis of 586 cases of children aged 6 to 12 years old in the outpatient department was established. Personalized files were used to record the uncorrected visual acuity, optometry, slit lamp, fundus mirror and strabismus. The cumulative use time of electronic products ( including computer, mobile phone, iPad) , writing time, whether to play the piano and outdoor activities time with the eye situation were recorded. Statistical analysis of the age group of myopia, the cumulative use of electronic age in different age groups, writing time, whether playing piano and outdoor activities and the distribution of myopia occurred. · RESULTS: ( 1 ) With the increasing of age, the distribution of uncorrected eyesight was in children mostly mild myopia, and the proportion of mild myopia was significantly higher than that of moderate and high myopia. ( 2 ) Electronic products use time distribution:the proportion of playing electronic products ( including mobilephone, computers, iPad) accounted for 76. 8%, of which 9 years old, 10 years old the cumulative use of electronic products with a long time was higher than other age groups. ( 3 ) Distribution of writing time: the proportion of write homework ≤1h was significantly lower than the proportion of writing homework > 1h (37. 2% vs 62. 8%), of which 9 and 10 years old children cumulative write time was higher than other age group. ( 4 ) Distribution of playing the piano: the proportion of playing piano time less than 1h was significantly higher than the proportion of playing piano time more than 1h ( 89. 1% vs 10. 9%). ( 5 ) Distribution of outdoor activities: the proportion of outdoor activities ≤1h in children at school age was significantly higher than that of outdoor activities > 1h (91. 8% vs 8. 9%). ·CONCLUSION: With the age exposure to electronic products becoming younger, heavy learning tasks and less outdoor activities, myopia occurred in advance of age. So health examination and eye guidance, reducing the amount of work appropriately, increasing outdoor activities will slow the development of early childhood myopia.

OBJECTIVESince glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common hereditary hemolytic erythrocyte enzyme deficiency, most cases have single nucleotide mutations in the coding region, and current test methods for gene mutation have some missed detections, this study aimed to investigate the feasibility of RT-PCR sequencing in the detection of gene mutation in G6PD deficiency.
METHODSAccording to the G6PD/6GPD ratio, 195 children with anemia of unknown cause or who underwent physical examination between August 2013 and July 2014 were classified into G6PD-deficiency group with 130 children (G6PD/6GPD ratio <1.00) and control group with 65 children (G6PD/6GPD ratio≥1.00). The primer design and PCR amplification conditions were optimized, and RT-PCR sequencing was used to analyze the complete coding sequence and verify the genomic DNA sequence in the two groups.
RESULTSIn the G6PD-deficiency group, the detection rate of gene mutation was 100% and 13 missense mutations were detected, including one new mutation. In the control group, no missense mutation was detected in 28 boys; 13 heterozygous missense mutations, 1 homozygous same-sense mutation (C1191T) which had not been reported in China and abroad, and 14 single nucleotide polymorphisms of C1311T were detected in 37 girls. The control group showed a high rate of missed detection of G6PD deficiency (carriers) in the specimens from girls (35%, 13/37).
CONCLUSIONSRT-PCR sequencing has a high detection rate of G6PD gene mutation and a certain value in clinical diagnosis of G6PD deficiency.

Objective To develop an effective way to evaluate the accurate platelet count in a patient with anticoagulants-induced pseudothrombocytopenia (PTCP).Methods It was studied that various anticoagulants effect on the platelets count for an infrequent patient with anticoagulants-dependent PTCP. When vitamin B6,aminophylline,gentamicin and amikacin were separately added to four anticoagulated blood samples from anticoagulants-dependent patient within 15 min after blood withdrawal,platelets count and morphological changes of blood cells after 4 hours of incubation at room temperature were investigated. The best anti-aggregating agent and its optimal concentration among them were explored.Results The four anticoagulants all could not inhibit the aggregation of the patient's platelets.Only amikaein among the above anti-aggregating agents can prevent and dissociate the aggregation of platelets without apparent morphological changes of blood cells and the platelet counts was stable within 4 hours after blood drawn when amikacin was added either before or after blood sampling.With increasing the concentration of amikaein,the platelet counts increase and then tend to be stable.The optimal concentration of amikacin is 5 mg/ml blood.Conclusions The supplementation of amikaein either before or after blood sampling is a useful method for the diagnosis anticoagulants-dependent PTCP and for the eva/uation of platelet counts in infrequent patients with anticoagulants-dependent PTCP.

OBJECTIVETo search for a safe and convenient surgical method for management of urethral disruption.
METHODSWe performed urethral realignment for 18 cases of posterior urethral disruption and 4 cases of ruptured bulbous urethra using the urethral guidance probe following bladder puncture stoma.
RESULTSUrethral realignment was accomplished in 21 of the cases, 18 under epidural and 3 under local anesthesia, with the mean blood loss of 20 ml and the average operation time of 18 minutes. Open surgery was necessitated in 1 case due to the complication of bladder rupture. Routine postoperative urethral dilation extended for 3 months, and all the cases were followed up for 3 to 24 months. The maximum urine flow rate was 15-22 ml/s in 13 cases and 10-14 ml/s in 7. One case received urethral anastomosis 3 months later because of urethrostenosis.
CONCLUSIONSUrethral realignment with the urethral guidance probe is a safe, convenient and effective surgical strategy for the management of urethral disruption.

OBJECTIVETo study the effect of Fuzheng Sanjie recipe in regulating tumor-associated macrophages (TAMs) in Lewis lung cancer mice.
METHODEfforts were made to establish the Lewis lung cancer mouse model, weigh tumors and calculate the anti-tumor rate. The immunohistochemical method was used to examine the infiltration degree of CD68 + in tumor tissues in each group. ELISA was used to examine the content of IFN-γ, TGF-β, IL-4, IL-13, IL-6, IL-10, IL-12, TNF-α in mice serum.
RESULTCompared with the tumor-bearing model group, all of the other groups showed higher tumor inhibition rates, i. e. 50.28% for the DDP group, 34.37% for the TCM-preventing group and 66.76% for the Chinese and western medicine group, with statistical difference (P < 0.05), but without statistical difference in the infiltration degree of CD68+. The expressions of the IFN-γ, IL-6, IL-12 in tumor-bearing groups were lower than that in the blank control group, but with higher contents of IL-4, IL-13, TGF-β. Intervened with different drugs, there were significant differences in content among some relevant cytokines (P < 0.05), as well as statistical differences among the TCM prevention group, the Chinese and western medicine group and the tumor-bearing control group (P <0. 05) , but without statistical difference in TNF-α and IL-10 content from the tumor-bearing control group (P < 0.05).
CONCLUSIONFuzheng Sanjie recipe could reverse the immune remodeling effect and control the tumor growth by down-regulating the expressions of IL-4, IL-13, TGF-α in lung cancer immune microenvironment and up-regulating the expression of IFN-γ.

OBJECTIVETo analyze the similarities and differences of the clinical manifestations between the children with upper airway resistance syndrome (UARS) and obstructive sleep apnea-hypopnea syndrome (OSAHS), and to explore the clinical features and characteristics of sleep respiratory parameters.
METHODSUsing the double-blind method, all children were diagnosed as UARS or OSAHS through the polysomnography test and the results of all children were analyzed by a sleep technician and an otolaryngologist. Another ENT doctor recorded their clinical and physical examination in detail.
RESULTSPolysomnography showed that the apnea-hypopnea index (AHI) and the lowest oxygen in 253 children with OSAHS were 3.60[2.00;7.55] times/h and 0.90[0.85;0.91], and were 0.90[0.50;1.10] times/h and 0.95[0.92;0.96] in 102 children with UARS, the difference of the two groups by rank test was statistically significant. The proportion of UARS and OSAHS was more common during preschool period than during school-age period. The chief complaint in two groups was sleep snoring, and the main symptoms were sleep restless, attention deficit/hyperactivity and breath with mouth open. The incidence rate of above symptoms were as follows, 94.1%, 72.5%, 62.7% and 37.3% in children with UARS, 92.9%, 78.7%, 57.7% and 45.5% in children with OSAHS. The difference was not significant by chi-square test (P>0.05). Tonsil and adenoid hypertrophy were also observed in the two groups, the difference was not significant (chi2 = 0.27, P= 0.87). However, the children with OSAHS were more apt to have the sleep apnea than with UARS, the difference was statistically significant (chi2 = 34.07, P<0.001).
CONCLUSIONSThe clinical manifestations of two groups are similar, the difference between UARS and OSAHS can not be determined by the patient's clinical performance. Sleep apnea can be more easily observed in children with OSAHS than that in UARS, the final diagnosis is based on polysomnography.

Ongoing study on the chemical constituents of the roots of Macleaya microcarpa led to the isolation of eight compounds of derivatives of triterpenes and organic acids in addition to some previously identified benzophenanthridines. The eight compounds were identified by spectroscopic methods as well as comparison with literature values as 1-oxo-2, 22 (30)-hopandien-29-oic acid (1), 3-oxo-12-oleanen-30-oic acid (2), 3α-hydroxy-12-oleanen-30-oic acid (3), 3β-hydroxy-12-oleanen-30-oic acid (4), ferulic acid (5), ferulic acid 4-O-β-D-glucoside (6), 3-O-feruloylquinic acid (7), and methyl 3-O-feruloylquinate (8). Of which, 1 is a new triterpenoid of hopanes and 2-8 are isolated from M microcarpa for the first time. In order to discover natural active compounds as potential agents of anti-ulcerative colitis (UC), an in vitro drug high-throughput screening model targeted x-box-binding protein 1 (xbp1) was employed to evaluate the activity of the major chemical constituents of M microcarpa. The result confirmed that two dihydrobenzophenanthridines, dihydrosanguinarine (9) and dihydrochelerythrine (10), showed a certain activity on activating the transcription of xbpl, a transcription factor (TF) associated with the occurrence, development, and potential treatment of UC, with their relative activating ratios being 1.76 and 1.77 times, respectively, as compared with control group.
