Objective To investigate the clinical features, etiological classification and staging of epiretinal macular membrane(MEM). Methods Clinical materials of 194 cases of MEM diagnosed by fundus fluorescein angiography in outpatient department of eye clinic in this hospital from 1983 to 2000 were retrospectively analyzed. Results There were typical clinical symptoms and signs of MEM in all of this 222 eyes of 194 patients. Etiological classification revealed that 4 cases were congenital(2.12%), 22 cases were secondary(11.34%), and 168 cases were idiopathic(86.60%). Staging of course of disease indicated that 119 eyes were in early stage(53.60%), 72 eyes were in middle stage(32.43%), and 31 eyes were in late stage(13.96%). Conclusion MEM may be classified as congenital, secondary and idiopathic type according to its pathogenesis, as early, middle and late stage according to the clinical course of disease. This can be helpful in treating the disease.

The effects of Amrinone (AMR)on left ventricular function in 30 cases of congestive heart failure patients was assessed by M-mode and pulsed Doppler echocardiography. AMR improves the systolic and diastolic function of left ventricle during and after 10 min (AMR lmg ? kg-1, infusion ). The mean stroke volume increased 20% and 18% ; cardiac output increased 23% , 19% ; cardiac index increased 23% and 23% ; ejection fraction increased 32% , 30%; mVcf increased 50% and 48% ; filling velocity in early diastole increased 30% and 21 %; respectively. There were no significant differently between during and after AMR infusion, but there were signifcantly difference a-mong before, during and after AMR infusion. The heart rate changed slightly without statistic significance. The results suggest that AMR could improve the systolic and diastolic function of left ventricle in congestive heart failure patients.

A new sonographic pattern of fetal hydrocephalus-midline-waved sign, and its mechanism were reported in this paper. When the abdominal wall of the pregnant woman was percussed by hand during ultrasound examination, the wave of midline echo was observed on sonoimage. The diagnosis of hydro-cephalus was made by this sign in all 12 fetuses, and confirmed by autopsy. No dilatation of the cerebral ventricle was observed in 5 out of 12 fetuses. It would be difficult to make the diagnosis of hy-drocephalus would previous diagnostic criteria be used. This sign is negative in normal fetuses, therefore-this finding has the practical value in the early and differential diagnoses of hydrocephalus.

OBJECTIVETo investigate the therapeutic effect of heating and bandage treatment for chronic lymphedema of extremities accompanied with erysipelas.

METHODSFrom March 2004 to March 2013, 80 patients with chronic lymphedema of extremities accompanied with erysipelas were analyzed retrospectively. The patients underwent heating treatment (42 degree centigrade) with infrared light machine made by Shanghai Ninth People's Hospital, 2 hours a day, 20 hours for a session. Bandage treatment was adopted after heating treatment. 1 or 2 sessions were performed for each patient every year. The erysipelas occurring frequency, patients subjective feeling, treatment sessions and elastic material usage was recorded during the follow-up period. The erysipelas occurring frequency was tested by the method of rank and inspection. SPSS 17. 0 was used for statistical analysis.

RESULTSAfter heating and bandage treatment, the occurrence frequency of erysipelas was obviously controlled (Z = 7.598, P = 0.000). Erysipelas was not occurred any more in 60 (75%)patients. Remarkable reduction of occurrence frequency of erysipelas caused by various reasons was showed after treatment. Primary and secondary lymphedema after treatment were compared with those before treatment respectively, showing statistical difference (Z = 3.417 and 5.009, P = 0.001 and 0.000). Most of patients felt better subjectively. The relapse rate of erysipelas and lymphedema was lower if keeping using elastic material to give more pressure on extremities after therapy.

CONLUSIONSHeating and bandage treatment can obviously reduce the occurrence frequency of erysipelas. It can improve the quality of patients' lives. Simultaneously, the subsequent elastic material pressure therapy is essential.

Objective To investigate the viral etiology and the epidemilogy of acute upper respiratory tract infection in Hebei Province from 2013 to 2015,providing scientific basis for diagnosis,prevention and control of the respiratory tract infection.Methods l 551 throat swab samples of the acute upper respiratory infection patients from four hospitals in Hebei Province were collected,Multiplex real-time PCR was used to detect 15 kinds of respiratory tract viruses for all specimens after nucleic acids extraction.Results Totally 714 positive samples were obtained from 1 551 samples,with a positive rate of 46.03％.Human rhinovirus(186,11.99％)was detected as the most common viral species,followed by human parainfluenza 3(167,10.77％),respiratory syncytial virus (122,7.87％),adenovirus (108,6.96％),influenza B virus (56,3.61％),human metapneumovirus(40,2.58％),influenza A virus(39,2.51％),human boca virus (38,2.45％),human parainfluenza 1 (35,2.26％),human coronavirus-229E/NL63 (33,2.13％),human enterovirus (32,2.06％),human parainfluenza 4(31,2.00％),human coronavirus-OC43 (30,1.93％),and human parainfluenza 2(11,0.71％).176 cases (11.35％) were detected as co-infection.The infection rate(56.07％) of under 5 years old group was higher than that of other groups.Conclusions The predominant respiratory viruses,who are responsible for acute upper respiratory tract infections in Hebei Province,are HRV,PIV3,RSV,ADV and IFV.Each virus possess the specific epidemiological feature.

Smu_195c is a protein with 86 amino acids in Streptococcus mutans, a primary pathogen for human dental caries. The specific function of Smu_195c is still unknown and there are no conserved domains in it. In order to find out its function, the gene encodes Smu_195c was cloned and expressed in E. coli as N-terminally 6*His tagged recombinant protein. Two crystal forms were obtained by the hanging drop method. Form Ⅰ belongs to space group P6122 or P6522 with the unit cell parameters a = b = 62.93 (A), c= 90.63 (A), γ=120° and form Ⅱ belongs to the space group P41212 or P43212 with the unit cell parameters a =b=57.97 (A), c = 103.51 (A).Crystals from the protein with His-tag belong to form Ⅰ, however, crystals from the protein without His-tag belong to both.

Objective To investigate the effects of music therapy in treating cognitive dysfunction in early stroke patients. Methods Forty patients who had suffered a stroke in the previous four weeks were randomly di-vided into two groups of 20. One received music therapy as part of their cognitive training ( observation group) , and the other did not (control group). Before and after 6 weeks of treatment, cognitive functioning was evaluated using the second Chinese edition of Loewenstein's occupational therapy cognitive assessment (LOTCA). The patients' a-bility in the activities of daily living was also evaluated using the modified Barthel index (MBI). Results After treatment, the total LOTCA and MBI scores in both groups were significantly higher than before. Both LOTCA and MBI scores in the observation group were significantly higher than in the control group, and there were also signifi-cant differences between the observation and control groups on all of the LOTCA sub-items except spatial percep-tion. Conclusions Music therapy can improve the effects of rehabilitation on cognition and the ADL ability of early stroke patients.

Objectives To explore the clinical application of deceleration capacity of rate (DC), acceleration capacity of rate (AC) and heart rate variability (HRV) in children with precardial distress of unknown origin. Methods A total of 56 children with precardial distress of unknown origin and 63 healthy children aged 6 to 17 years were examined by 24 h dynamic elec-trocardiogram, and the indexes of DC and HRV were compared between these two groups. Results DC value of children with precardial distress is less than that of the control group (P<0.05), AC value is greater than that of the control group (P<0.05), and heat rate (HR) is greater than that of the control group (P<0.05). No statistical differences were observed in the indexes of HRV between the two groups. The indexes of DC show a signiifcant positive correlation with HRV in children with precardial distress(r=0.27~0.40, P<0.05), while appear a negative relation with HR (r=-0.46, P=0.000). In contrast, the indexes of AC show a signiifcant negative correlation with HRV (r=-0.57~-0.34, P<0.05), and appears a positive relation with HR(r=0.61, P=0.000). HR value is higher in male children less than 12 years old with precardial distress than that of age-matched males in control group, and RMSSD is lower than the latter. DC value of male children more than 12 years with precardial distress is lower than that of age-matched males in control group, while AC value is higher than that of the latter;DC value is signiifcant lower in fe-male children more than 12 yeares with precardial distress than that of age-matched females in the control group (P<0.05). Con-clusions The activity of vagus nerve in children with precardial distress of unknown origin is decreased. DC value is signiifcantly lower than that of control group, and shows correlation with indexes of HRV. There is no signiifcant difference in DC and HRV value between male and female children with precardial distress. DC value is lower in children aged 12 or older with precardial distress than that of age-matched children in the control group, which indicates adolescents are vulnerable to autonomic nerve functional disorder.
