AIM: To evaluate the changes in central corneal thickness (CCF) caused by mydriasis with Mydrin-P.METHODS: A total of 106 eyes of 53 patients with refractive errors were studied. Each eye had instillation of Mydrin-P to obtain mydriasis. CCT was examined before and after mydriasis using ultrasonic pachymeter.RESULTS: CCT increased significantly after mydriasis with Mydrin-P.CONCLUSION: Mydrin-P can affect the measurement of CCT.

OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).

METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.

RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).

CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.

Clinical practice record manual contains the information about medical students' clinical studying process, clinical teaching process and the concept of clinical teaching management. First, we should design and optimize clinical practice record manual and then collect and analyze the relevant data. In addition, we should give the analysis to the students, teachers, clinical departments and hospitals on time, and at the same time, get their feedback. Through these steps, we can find and solve the problem efficiently and promote the quality of teaching, learning and management of clinical internship, so as to improve the clinical teaching quality control standard.

This paper is based on conflicting issues in clinical teaching between undergraduates and residents, also around cultivating goals on clinical competency. In order to enhance medicine-education collaboration and conception of continue education and improve clinical teaching management system for integration of undergraduates and residents, five measures should be put into practice. First, define the re-sponsibility of physicians at all levels. Then, accord training standards for clinical teachers' admission. Next, accord clinical teaching norms and documents. In addition, clinical teaching assistants are selected from intermediate physician for guiding clinical teachers. Finally, explore the integration of clinical teaching mood for training between undergraduates and residents, to promote the connection of clinical teaching for graduates and residents.

OBJECTIVETo explore the relationship between exon 3 mutation in the methyl CpG-binding protein 2 (MeCP2-E3) gene and Hirschsprung disease (HSCR) and anorectal malformations (ARMs).

METHODSPCR and DNA sequencing were used to detect the mutation of MeCP2-E3 in 120 healthy controls, 120 HSCR, and 50 ARMs.

RESULTSOn sequencing, 45(37.5%) children with HSCR had basic replacement in MeCP2-E3, 12(10.0%) of them were homozygous mutation. Fourteen(28.0%) children with ARMs had basic replacement in MeCP2-E3, 4(8%) of them were homozygous mutation. There were no mutation in the control group.

CONCLUSIONSMutation of MeCP2-E3 is present in the peripheral blood of children with HSCR or ARMs, which may contribute to the development of Hirschsprung disease or anorectal malformations.

Objective To observe the prevalence of hyperuricemia(HUA)among obese children,and to ex-plore the association between uric acid(UA)levels and cardiometabolic risk factors,acanthosis nigricans and non - al-cohol fatty liver disease(NAFLD). Methods By using representative sampling method,1 753 obese children aged 6 -17 years old from 18 schools in 3 districts of Beijing(Xicheng,Haidian,Miyun)were selected to participate in the clini-cal examinations,including anthropometric measurements(height,weight)and blood pressure. Serum biochemical pa-rameters were assessed,including fasting plasma glucose(FPG),total cholesterol(TC),triglyceride(TG),high - densi-ty lipoprotein cholesterol(HDL - C),low - density lipoprotein cholesterol(LDL - C)and UA. Acanthosis nigricans and B - model ultrasonography of the liver were conducted. Results The prevalence of hypertension,impaired fasting glu-cose,dyslipidemia,acanthosis nigricans,and NAFLD among these 1 753 obese children was 33. 6%(589 cases), 66. 5%(1 156 cases),54. 3%(943 cases),23. 3%(408 cases),and 17. 0%(298 cases),respectively. The preva-lence of HUA was 40. 70%(714 / 1 753 cases),with 50. 17%(581 / 1 158 cases)in boys and 22. 34%(133 / 595 ca-ses)in girls. There was a significant increase in body mass index,systolic blood pressure,diastolic blood pressure, FPG,TG and LDL - C with the increase of UA,but there was a decrease in HLD - C with the increase of UA(all P ﹤0. 05). In boys,the adjusted odds ratios( OR)and 95% CI of the highest quartile of UA for hypertension,impaired fasting glucose,dyslipidemia,acanthosis nigricans,and NAFLD were 1. 16(0. 77 - 1. 74),1. 34(0. 90 - 1. 99),1. 29 (0. 89 - 1. 87),1. 89(1. 17 - 3. 04),and 1. 71(1. 03 - 2. 84),respectively;in girls,the adjusted OR and 95% CI of the highest quartile of UA for hypertension,impaired fas-ting glucose,dyslipidemia,acanthosis nigricans,and NAFLD was 0. 70(0. 40 - 1. 24),0. 60(0. 40 - 1. 00),1. 69(1. 04 - 2. 70),1. 67(0. 80 - 3. 49),and 1. 33(0. 48 - 3. 66),re-spectively. Conclusions The prevalence of HUA is relatively high in obese children and there is a strong association between UA and some car-diovascular metabolic disorders,acanthosis nigricans and NAFLD.

OBJECTIVETo investigate the effect of advanced maternal age on birth defects and postnatal complications of neonates.

METHODSAmong the 1 109 neonates who were born at The First People's Hospital of Yunnan Province between January 2014 and December 2015, 536 neonates whose mothers were aged ≥35 years were enrolled as advanced age group and 573 neonates whose mothers were aged <35 years were enrolled as appropriate-age group. The incidences of the comorbidities in pregnancy, fetal intrauterine distress, neonatal birth defects, and postnatal complications were compared between the two groups. A univariate logistic regression analysis was performed to analyze the effect of advanced maternal age on neonatal comorbidities during perinatal period.

RESULTSCompared with the appropriate-age group, the advanced age group had significantly higher rate of caesarean section and incidence rates of multiple birth, gestational diabetes, pregnancy-induced hypertension, in vitro fertilization, and fetal intrauterine distress (P<0.01). The neonates in the advanced age group had a significantly higher incidence rate of cleft lip and palate and a significantly lower rate of skeletal dysplasia than in the appropriate-age group (P<0.05). Advanced maternal age was the risk factor for fetal intrauterine distress (OR=2.27, 95%CI: 1.33-3.88, P=0.003), neonatal resuscitation (OR=1.66, 95%CI: 1.19-2.31, P=0.003), and intracranial hemorrhage (OR=2.70, 95%CI: 1.21-6.04, P=0.02).

CONCLUSIONSThe women of maternal advanced age have higher incidence rates of pregnancy comorbidities than those of appropriate age, and the neonates born to the mothers of advanced maternal age have a higher incidence rate of cleft lip and palate. Advanced maternal age may increase the risks of fetal intrauterine distress, neonatal resuscitation, and intracranial hemorrhage.

OBJECTIVETo study the subcellular localization of severe fever with thrombocytopenia syndrome virus (SFTSV) in macrophages and understand the replication and assembly mechanism of SFTSV in host cells.

METHODSUsing two types of human macrophage cell lines THP-1 and U937, the study analyzed the intracellular colocalization of SFTSV with Golgi apparatus and endoplasmic reticulum by immunefluorescence staining and confocal microscopy.

RESULTSSFTSV infected macrophage cell lines THP-1 and U937. Immunofluorescence staining showed that the SFTSV nuclear protein colocalized with Golgi apparatus and closely surrounded by endoplasmic reticulum in the perinuclear region.

CONCLUSIONThe results suggested that Golgi complex and endoplasmic reticulum are probably the sites for formation and maturation of SFTSV viral particles.
