Objective: To explore the cognitive level and the mental status of the patients suffering from perimenopausal syndrome in Shanghai, and to identify the traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome. Methods: The cognitive level of the perimenopausal women was evaluated by using general living problem questionnaire. The mental status of the perimenopausal women was evaluated by using self-rating depressive scale. The traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome was identified by using traditional Chinese medical symptoms questionnaire. Results: A total of 634 perimenopausal women finished the investigation. There were 74.76% (474/634) patients who knew little about the perimenopausal syndrome; 77.29% (490/634) patients had a depressive tendency; 8.36% (53/634) patients had depressive disorder. There were 72.40% (459/634) patients who had the symptoms such as susceptibility to anger and restlessness, restless sleep at night, thirst with dry throat and bitter taste, and all these symptoms could be classified into hyperactivity of heart and liver fire syndrome. Conclusion: Patients suffering from perimenopausal syndrome know little about this disease and mostly have depressive tendency, and the major traditional Chinese medicine syndrome pattern is hyperactivity of heart and liver fire based on the chief clinical manifestations of the patients.

Objectives To investigate the significance of electronic bronchoscopy and bronchoalveolar lavage in diagno-sis and treatment in children with pulmonary mass lesion. Methods A total of 74 hospitalized children from January 2011 to June 2012 whose imaging examinations showed massive patchy shadow were examined and treated by electronic bronchoscopy and bronchoalveolar lavage. Their clinical data were retrospectively analyzed. Results The major cause for the massive shadow was infection according to electronic bronchoscopy examination (68/74, 91.89%), 65 cases of them were lobar pneumonia, 3 cas-es were pulmonary tuberculosis followed by 5 cases of foreign body (6.76%) and one case of pneumorrhagia (1.35%).The lower left lung was the most frequently seen site of infection, followed by lower right lung. The agreement between infection sites and imaging examination was 97.30%. Bronchoalveolar lavage fluid showed that the primary pathogen of lobar pneumonia infection is Mycoplasma pneumoniae (MP) (42/65, 64.62%). The highest detection rate of MP was found in preschool group and the detec-tion rate between different age groups indicated statistically significant difference (P<0.01). The imaging examination showed pulmonary lesions in 61.54%children with lobar pneumonia improved significantly in one week. The improvement rate of pul-monary lesions was higher in infected children with short duration (1-2 weeks, 90.91%) between disease onset and electronic bronchoscopy inspection than those with longer duration (2-3 weeks, 51.72% and >3 weeks, 35.71%) (P<0.05). Conclusions Electronic bronchoscopy and bronchoalveolar lavage play dual roles in etiological diagnosis and therapy in children with pulmo-nary mass lesion.

Objective To discuss the pulmonary function change in infants with human bocavirus (HBoV) pneumonia or mycoplasma pneumonia (MP) and its clinical signiifcance. Methods One hundred and forty infants under 3 years old who were admitted due to pulmonary infection were recruited from January, 2013 to October, 2013. Among them, HBoV-DNA was detected in 64 cases, and MP-DNA was detected in 76 cases. Thirty eight normal age-matched infants were selected as controls. The shape of tidal breathing lfow-volume loops (TBFVLs) and change of every index were measured with a Pulmonary Testing System (Jaeger MasterScope). Results The ratio of time to peak tidal expiratory lfow (PTEF) to total expiratory time (TPTEF/TE), the ratio of VPTEF to expiratory volume (VPTEF/VE), tidal expiratory lfow at 25%of the remaining tidal volume (TEF25%) and the ratio of TEF25%to PTEF (25/PF) were signiifcantly decreased in infants with HBoV and MP infection as compared with healthy infants (P<0.05). However, there was no signiifcant difference of the above indices between infants with HBoV and MP infection (P>0.05). The shape of TBFVLs in infants with HBoV and MP pneumonia was changed and characterized by left-shifted PTEF and trough-like concave in descending limb. The PTEF was decreased in infants with pulmonary infection. Conclusions HBoV or MP infection results in impaired pulmonary function with manifestations of obstruction in small airway. The shape of TBFVLs in infants with HBoV and MP pneumonia is characterized by left-shifted PTEF and trough-like concave in descending limb.

Objective To study the epidemiological and clinical features of human parainfluenza virus (HPIV) infection in children in Suzhou,and to provide the evidence-based foundation for early warning,diagnosis and treatment of respiratory infection in children.Methods The sputum specimens and medical history were obtained from children with acute respiratory tract infection hospitalized at the Childen's Hospital Affiliated to Soochow University from January 2006 to December 2015.Seven kinds of common respiratory viruses including respiratory syncytial virus,influenza virus A,influenza virus B,HPIV Ⅰ,HPIV Ⅱ,HPⅣV Ⅲ and adenovirus were detected by using the direct im-munofluorescence.Mycoplasma pneumoniae(MP),chlamydia pneumoniae,human bocavirns (hBoV) were detected by using fluorescence quantitative PCR.Rhinovirus and human metapneumovirus were detected by using reverse transcription-PCR.Sputum was cultured for bacteria.Results In 21 769 cases,the detection rate of HPIV positive was 3.21％ (829 cases),among which,HPIV Ⅰ,HPIV Ⅱ,HPIV Ⅲ were respectively detected in 113 cases (0.52％),16 cases (0.07 ％) and 700 cases (3.21％),respectively.There were 378 cases of simple infection and 428 cases of mixed infection,and the mixed infection was very common in Streptococcus pneumoniae,Haemophilus influenza,MP and hBoV.There was a difference in HPIV infection among genders,and the detection rate of the boys was higher than that of girls[4.14％ (563/13 591 cases) vs.3.25％ (266/8 178 cases),x2 =11.036,P =0.001].In the 28 d-1 year old and ＞ 1-3 year old group,the detection rate of HPIV was higher[4.71％ (494/10 476 cases) and 4.21％ (244/5 793 cases),respectively].In spring and summer,there was a higher detection rate of HPIV infection.The clinical manifestations with simple infection of HPIV Ⅰ and HPIV Ⅲ were cough,fever and wheezing.The rate of fever and shortness of breath in those of HPIV Ⅰ was 71.74％ (33/46 cases),10.87％ (5/46 cases),and that in HPIV Ⅲ was 40.12％ (134/334 cases),2.10％ (7/334 cases),HPIV Ⅰ infection was more likely to cause fever and shortness of breath than those of HPIV Ⅲ,there were significant differences (x2 =16.410,P ＜ 0.001;x2 =10.177,P =0.001).Pneumonia had the highest detection rate of viral infection.Conclusions HPIV Ⅲ is the leading pathogen among the types of HPIV in the hospitalized children in Suzhou area.Among the subtypes of HPIV,the peak of HPIV infection occurs in spring and summer.The children less than 3 years old are the most susceptible to parainfluenza virus,and the HPIV detection rate is gradually declines with age.
