AIM:To evaluate the poor vision condition and analyze the myopia etiological factor in primary school He'xi district of Sanya.
METHODS: A cohort of 1 218 subjects were recruited randomly from grade 1~6 of two primary schools. Visual activity test, dioptroscopy and risk factor questionnaire were evaluated.
RESULTS: The prevalence of poor vision was 29. 55%. The incidence of myopia increased with grade, and was significantly higher in girls than that in boys. The outdoor activity time of myopic pupil ( 7. 25 ± 5. 35h/wk ) was significantly lower than emmetropic pupil (11. 86±6. 65h/wk) ( P < 0. 05 ). The usage of electronic product ( TV, computater and cell phone) time of myopic pupil (13. 36±8. 35h/wk) was significantly higher than emmetropic pupil (7. 75±5. 83h/wk) (P<0. 05).
CONCLUSION: The increase of myopia incidence is closely related with sparing outdoor activity and excess usage of electronic product.

Objective: To develop parental punishment style the questionnaire. Methods: Based upon previous literature about parental punishment style and expert interview, data were collected for the parental punishment style questionnaire. A sample of 1028 junior high school students were asked to complete the questionnaire and 158 of them was given retest after a month. Results: Taken from the questionnaire by exploratory factor analysis four factors were compatible. The results of confirmatory factor analysis showed a good fit to the data. The internal consistency reliability of father and mother questionnaire was satisfactory, with Cronbach ? coefficient 0.91; and the test-retest reliability was also satisfactory, with test-retest correlation coefficient 0.88 and 0.89, which showed good content validity and high construct validity. Conclusion: The questionnaire has good reliability and validity, and meets the need of psychometrics.

Objective To explore the correlation between vitamin A (VA) level andMycoplasma pneumonia (MP). Methods Children aged 0-12 years hospitalized with acute infectious respiratory diseases during March 2015 to December 2015 were randomly selected. The level of serum VA was detected by high performance liquid chromatography (HPLC). MP-DNA on nasopharyngeal swab was detected by polymerase chain reaction (PCR). The serum MP-IgM was detected by enzyme linked immunosorbent assay (ELISA). The MP infection rate among subclinical VA deficiency (SVAD) group, suspicious subclinical VA deifciency (SSVAD) group and VA normal group were analyzed and compared.Results Among 600 children, there were 83 cases of SVAD (13.83%) and 193 cases of SSVAD (32.17%). There were statistical differences of the incidences between SVAD and SSVAD in children younger than 1-year-old, 1-3 years old, 3-6 years old and≥6 years old (P all<0.001), among which SVAD and SSVAD groups had the highest incidence rates in infants younger than 1 year old (26.36% and 49.10%respectively). Among 600 children, MP was positive in 201 children (33.5%), in whom 57 children (28.35%) were SVAD and 70 children (34.83%) were SSVAD. The incidence rate of SVAD in children with MP positive was higher than that in children with MP negative (P<0.001). In 201 children with MP positive, there were signiifcant differences in the distribution of SVAD, SSVAD and VA among different age groups (P=0.003), and the incidence rate of SVAD in infants younger than 1 year old was higher (48.39%).Conclusions SSVAD and SVAD are common in infants younger than 1 year old; SVAD may be associated with MP infection in children.

In this study, by using the method of literature research, 35 prescriptions related to asthma therapy has been screened out from Hui medicine through collecting the ancient and modern literature. A comparison of fragrant medicine between the name in Arab and Chinese herbal medicine is done. The countif function in Microsoft Excel 2007 is used to get the prescriptions of the drug on the frequency statistics, summarizing the common drugs of Hui medicine for asthma are Pinellia, almond, white sugar, walnut. According to the commonly used drugs, the pathogeny and treatment principle about Hui medicine for asthma is preliminarily inferred combining literature research and the related Hui medical theory. In this study, those prescriptions have been classified into 21 cases which are effective and can be used in medical therapy according to the relevant literatures with the development of the Hui people in their long process of formation of the unique diet culture, 14 useful and convenient Halal diet therapies are made up according to the indications, therapies, party name and composition. Halal diet and "medicine and food" herbs are preliminarily analyzed and summarized, which can be convenient for the people to reduce pains through the diet and improve health awareness.

Objective To improve the knowledge,diagnostic level on concealed penis in children,and explore the operative treatment methods of concealed penis.Methods Ten children with concealed penis were reviewed retrospectively in the First Hospital of Jilin University from Jun.2005 to Jul.2007.Patients were 6-12 years old.Penis length was 1.2-2.6 cm.Patients growthing and micturition were normal,the results of androgne and estrogen examination were normal.The etiology was simple obesity in one case,fiber streak of penis sarcolemma in 9 cases.The clinical symptoms and signs,diagnosis and operative method were analyzed.Results The diagnosis of 10 children were correct,and all patients were treated by Devine's operation and 10 cases patients had healed in one stage.There was no vessel,nerve and urethra injury during the operation.The length of penis was 3.0-5.5 cm,average in 3.6 cm after operation.Followed up 3 months to 2 years,10 children's phimosis were removed,the micturition were normal;the appearance of penis was also satisfactory after operation.One patient with under-developed penis had a amelioration after treatment with HCG postoperatively.The penis contour was dissatisfactory in 1 obesity patient,but it was ameliorated gradually while growing up.Conclusions The correct diagnosis and differential diagnosis are very important for operative treatment depend on the different etiology and pathologic changes of concealed penis.Suitable operation can extend the length;moreover,ameliorate the symptom of micturition and the appearance of the penis.

Objective To investigate the oxalate-degrading and growth abilities of lactic acid bacteria coming from yoghourt in vitro culture broth. Methods The species of lactic acid bacteria obtained from 6 brands of yoghourt were identified. Different brands of yoghourt were separately cultured in broth and incubated at 37 ℃,5% CO2 for 48 h, getting the concentration of lactic acid bacteria through slab counting method. The brand of yoghourt with the highest quantity of bacteria was chosen as the study subject. Three species of bacteria and the mixture bacteria obtained from the chosen brand of yoghourt were cultured separately for 72 h in MRS broth which contained three different concentrations of ammonium oxalate, and the broth without inoculating of bacterium was prepared as control. The amount of bacteria in culture was detected, the concentration of ammonium oxalate was detected through photometric determination of oxalic acid by its catalytic reaction of methyl red by potassium chromate. Results Three species of lactic acid bacteria (L.bulgaria, L.acidophilus and L.thermophilus) were detected in each brand of yoghourt. The quantity of bacteria in Weiquan yoghourt is the highest. After 72 h incubation, the concentrations of oxalate in all the broths containing bacteria were lower than those in the control. L.acidophilus showed the best degrading activity. The higher the concentration of oxalate was, the bigger the amount of oxalate degraded was, the smaller the percent of degrading was, and the less the growth ability of bacteria was. Conclusion All the species coming from yoghourt have the ability of oxalate degrading, which increases with the concentration of oxalate in culture.But the high concentration of oxalate restrains the growth of bacteria.
