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 study the mechanism of sacral plexus injury resulting from anteroposteri- or compression zone-Ⅱsacral fractures.Methods Six short-term(within one year)embalmed pelves were obtained from Anatomic Department of Hebei Medical University.The preserved sacral plexus and re- sected pubic symphysis were used to make the models of anteropesterior compression zone-Ⅱsacral frac- tures.Quantitative analysis for fracture displacement was carried out to observe the characteristics and mechanism of sacral plexus injury.The removed sacral plexus was replaced by proportional diameter silica gel pips filled with contrast medium.The experimental procedure was repeated under X-ray.The experi- mental data were analyzed by SPSS 10.0 statistic software to obtain result.Results In anteropostefior compression sacral fracture,sacral nerve canal was gradually opened and its volume raised.No sacral nerve was opressed in nerve canal.However ilium external rotation prolonged sacral nerves,especially S_1,S_4 and the more the pubic symphsis was separated the more the sacral plexus nerves were prolonged.At the same time,the sharp border of fracture segment stabbed the nerves,especially L_5(6 cases),S_1(5 cases)and S_2 (3 eases).Conclsions Sacral plexus is tightly connected with the wall of pelvic cavity and fixed. When zone-Ⅱsacral fractures happen sacral plexus is easily damaged.In anteroposterior compression sacral fracture,nerves S_1 and S_4 are likely to be damaged by dragment,and nerve compression injury is attributed to stabbing by fracture segment border,with L_5 and S_1.more hackneyed.

Objective To evaluate the feasibility to detect Prototheca in a mouse model of Prototheca zopfii cutaneous infection by using fluorescence in situ hybridization (FISH).Methods The model of Prototheca zopfii cutaneous infection was established by abdominal subcutaneous inoculation of Prototheca zopfii suspensions into 20 male BALB/c mice.Seven days after the inoculation,the mice were sacrificed,and tissue specimens were obtained from abdominal skin and subjected to microscopic examination,fungal culture and paraffin embedding.A PZ-probe was artificially synthesized and used to detect Prototheca in paraffin-embedded sections by using FISH.Moreover,both periodic acid-Schiff (PAS) and hematoxylin-eosin (HE) staining were performed to examine the paraffin-embedded sections.Skin specimens obtained from normal mice and Candida albicans-or Cryptococcus neoformans-infected mice served as the negative control.Results Clinical presentations,pathological examination and fungal culture results all confirmed the successful establishment of Prototheca zopfii skin infection model in mice.Prototheca was identified by FISH with the PZ-probe in the paraffin-embedded skin tissue sections from the murine model of Prototheca zopfii cutaneous infection,but not detected in the negative control tissue specimens,which was consistent with the results of PAS and HE staining.Conclusion FISH can be used to detect Prototheca in paraffin-embedded skin sections from the mouse model of Prototheca zopfii cutaneous infection.

BacKground:Helicobacter pylori ( Hp ) infection is an important etioIogicaI factor of gastric uIcer. AIthough eradicating Hp can heIp gastric uIcer heaIing,there is stiII a high recurrence rate of gastric uIcer. Therefore,other factors pIaying a roIe in the pathogenesis of gastric uIcer shouId be in concern. Aims:To investigate the non-reinfectious recurrence factors of gastric uIcer after Hp eradication. Methods:A totaI of 164 newIy diagnosed gastric uIcer patients with Hp infection from January 2011 to June 2012 at Ren Ji HospitaI,SchooI of Medicine,Shanghai Jiao Tong University were enroIIed. AII patients were given Hp eradication therapy and treatment of gastric uIcer. Patients with successfuI Hp eradication and heaIing of gastric uIcer were foIIowed up at 3,6,12 months after uIcer heaIing. Suspected risk factors of gastric uIcer recurrence were coIIected,and their reIationships with recurrence were anaIyzed. Results:A totaI of 123 patients positive for Hp infection compIeted the 12 months foIIow-up,gastric uIcer recurred in 18(14. 6%)of them. Chi-square test reveaIed that age,gender,smoking/drinking,non-steroidaI anti-infIammatory drugs( NSAIDs ),negative emotions and unheaIthy eating habits were significantIy associated with the recurrence of gastric uIcer(P<0. 05). Of the unheaIthy eating habits, irreguIar eating, and preference of indigestibIe food and fast food/carbonated drinks were significantIy associated with recurrence of gastric uIcer( P <0. 05 ). Conclusions:Patients with gastric uIcer shouId change their unheaIthy Iiving habits,foIIow rationaI use of drugs,and keep heaIthy mentaI status and eating habits for avoiding the recurrence of gastric uIcer.

Objective To explore the association between C reactive protein (CRP)with prostatic cancer (PCa)and benign prostatic hyperplasia (BPH).Methods Retrospective analysis the 110 patients of the First Affiliated Hospital of Zhejiang University In January 2010 to August 2012 whose TPSA>4 ng/ml,postoperative pathology confirmed the diagnosis of 54 cases of prostate cancer,5 6 cases of benign prostatic hyperplasia.Detected serum CRP levels by using transmission turbidim-etry and TPSA levels by using chemiluminescence immunoassay of 54 PCa and 56 BPH patients.According to the Gleason score,PCa patients were divided into high-risk and low-risk PCa two groups,the differences among high-risk PCa,low-risk PCa and BPH groups were analyzed by nonparametric statistics analysis.Results The CRP level of high-risk PCa was 4.20~2.12 mg/L,the CRP level of low-risk PCa was 1.90~0.91 mg/L and the CRP levels in BNP patients was 1.49±0.87 mg/L,the high-risk and low-risk PCa serum CRP level obviously higher than that of patients with BPH,the differences were statistically significant (P<0.05).Conclusion Serum CRP levels of PCa patients were increased significantly,espe-cially in high-risk PCa patients.

Objective: To study the effect of community intervention on mental health of patients with type 2 diabetes mellitus (DM) Method:Two communities in a city of Shandong province were chosen as intervention community and control community respectively after an epidemiological investigation of diabetes mellitus in 1997 After four years intervention, a case-control study was done by assessing mental status with SAS (self-rating anxiety scale), SDS (self-rating depression scale) and SSRS (social support rating scale) Result:Compared with baseline levels, after intervention for 4 years, the SAS score, SDS score and SSRS score (including subject score and object score) of patients in intervention community improved significantly, while the counterparts of patients in control community had no improvement But patients in intervention community still had poorer results than health controls By adjustment of the potential confounding effect of age, sex and occupations, diabetes mellitus still had influence on anxiety, depression and social support with ORs of 1 41, 1 69 and 0 69 respectively Multivariable stepwise analysis showed that, suffering from other chronic diseases was risk factor for mental health of diabetes patients, and the higher the education level, the better results of intervention Conclusion:The DM community intervention program improves mental health of patients significantly, but patients still have poorer mental health than healthy control Education level and suffering from other chronic disease are main factors having influence on effects of the intervention
