Chronic obstructive pulmonary disease and asthma are complex inflammatory diseases with airway obstruction as the main characteristics, and have become common respiratory diseases that seriously affect human health. Compared with the clinical use of PDE3 or PDE4 inhibitors alone, dual PDE3/4 inhibitors have synergistic anti-inflammatory and bronchodilator effects, and have attracted widespread attention in recent years. This article reviews the representative research results of dual PDE3/4 inhibitors currently in the preclinical and clinical research stages, summarizing their latest progress and their potential for the treatment of chronic obstructive pulmonary disease and asthma.

Since Fujita first described uvulopalatopharyngoplasty(UPPP)in 1981,UPPP and its modified procedures have been widely used to treat obstructive sleep apnea and hyponea syndrome(OSAHS).However,despite of its wide application,the success rates was uncertain,ranging from 20% to 80%,with patients of varing Friedman stages.It is well known that the principle of UPPP is to remove the redundant tissue of palate,elongated uvula and hypertrophic tonsils in order to widen the anteroposterior space at the level of palate.But recently,surgeons have found that not only the collapse of soft palate but also the collapse of lateral wall at the palate level can contribute to the obstruction of upper airway at the level of palate.As a result,many surgeries which can widen the lateral velopharyneal space have sprung up in these years.This review focuses on the development of techniques that emphasize the enlargement of lateral velopharyneal space in patients with OSAHS.

Objective To investigate the clinical characteristics and related risk factors of infarction secondary to severe traumatic brain injury.Methods 480 traumatic brain injury patients were chosen.Depending on the occurrence of cerebral infarction,patients were divided into TCI groups and non-TCI group,clinical symptoms and signs of TCI group were observed,and its related risk factors was analyzed.Results In 480 cases patients,there were 30 cases of patients with traumatic brain injury secondary to cerebral infarction,the rate was 6.25%.Clinical manifestations included unilateral limb motor and sensory dysfunction,visual dysfunction,language dysfunction,dizziness,headache.10 cases Prognosis were good,6 cases were mild disability,3 cases were severe disability,1 case was plant survival,10 patients died.Univariate analysis showed that the rates of aged ≥50 years,GCS score ＜ 8 points,hernia,hypotension,subarachnoid hemorrhage,large doses of non-dehydrating agent in the TCI group were higher than those of non-TCI group,the differences were statistically significant (x2 =12.311 3,14.725 4,19.867 8,5.296 9,9.242 6,11.713 6,all P ＜ 0.05).Logistic multivariate analysis showed that age ≥50 years,GCS score ＜ 8 points,hernia,cerebral hypotension were important risk factors.Conclusion Brain injury patients with cerebral infarction secondary to clinical manifestations have some characteristics.Age ≥50 years,GCS score ＜ 8 points,hernia,hypotension are important risk factors.

OBJECTIVE:To explore the optimal steaming time of Carapax trionycis during cleansing period,and to optimize and improve production technology of Carapax trionycis recorded by current Chinese Pharmacopoeia. METHODS:The mechanical processing replaced the artificial processing method in Chinese Pharmacopoeia. The content of protein and the appearance of Cara-pax trionycis were investigated after steaming for 30,60,90,120,180,240 min during cleansing period. The extract,decoction, ash content,appearance and property of Carapax trionycis decoction piece processed with vinegar were also investigated after cleansed Carapax trionycis decoction piece was processed by sand scalding and vinegar quenching method. RESULTS:The differ-ent steaming time obtained different quality of cleansed Carapax trionycis decoction piece and Carapax trionycis decoction piece pro-cessed with vinegar. Compared with decoction piece steamed for other duration,when the steaming time was 90 min,the content of protein in cleansed Carapax trionycis decoction piece was higher(31.16%),and its appearance was up to the requirement. Cara-pax trionycis decoction piece processed with vinegar had higher contents of extract and decoction(9.13%,11.39%)and lower con-tent of ash(66.29%),and its appearance was up to the requirement. CONCLUSIONS:Different steaming time have certain effect on the quality of cleansed Carapax trionycis and Carapax trionycis processed with vinegar,the optimal steaming time of Carapax tri-onycis is about 90 min during cleansing. The mechanical processing method maybe replace the artificial processing on Carapax tri-onycis for improving its production efficiency.

Objective To analyse the changes of a district general hospital before and after management by Shanghai Renji Medical Group through current situation survey,and explore the conditions for the development of district general hospitals.Methods The Zhujiajiao People's Hospital of Qingpu District in Shanghai was selected,and patients(n=50)and hospital staff(n=100) were conducted current situation survey with questionnaires which included the knowledge and evaluation of the hospital's current situation as well as the changes before and after management by Shanghai Renji Medical Group.Results Half year after management by Shanghai Renji Medical Group,great progress in medical work was achieved,with a favourable development trend.The rate of satisfaction on medical service evaluated by inpatients reached 89.60%,and 81.91% hospital staff had confidence in the sustainable development of the hospital. Conclusion Management by Shanghai Renji Medical Group has brought prospects for the Zhujiajiao People's Hospital.Under current environment,only certain conditions are met can a district general hospital achieve sustainable development.

In this study, the effect of prophylactic anti-inflammation on the development of smoke-induced emphysema was investigated. Young male guinea-pigs aged 1.5-2 months (weighing 198.3+/-26.9 g) were randomly divided into 4 groups: group A (cigarette smoke exposure only), group B (cigarette smoke exposure plus pentoxifylline-rich (PTX, 10 mg/d) forage feeding), group C (cigarette smoke exposure plus intermittent cortical steroid injection (Triamcinolone acetonide, 3 mg, i.m., every three weeks) and control group (group D: animals with sham smoke exposure, raised under the same conditions). Animals in group A, B and C were exposed to smoke of cigarettes for 1 to 1.5 h twice a day, 5 days a week. All animals were killed at the 16th week and followed by morphometrical analysis of the midsagittal sectioned lung slices. Smoke exposure of 16 weeks resulted in visible emphysematous development in Group A but not in Group B and C. It was evidenced by the indicator of air-space size, mean linear intercept (Lm): 120.6+/-16.0 microm in Group A; 89.8+/-9.2 microm in Group B and 102.4+/-17.7 microm in Group C. The average Lm in either group B or group C was shorter than that in Group A (ANOVA and Newman-Keuls test, F=8.80, P=0.0002) but comparable to that (94.8+/-13.2 microm) in group D (P>0.05). It is concluded that long-term prophylactic anti-inflammation inhibits pulmonary emphysema induced by cigarette smoking in the guinea pigs.

Objective To investigate the infection status in patients with vitiligo.Methods A total of 434 patients with vitiligo were collected eligible data by a uniform questionnaire.Anti-HEV IgG and anti-HEV IgM were detected by enzyme-linked immunosorbent assay(ELISA).The correlation between the positive rate of anti-HEV IgG and sex,age,duration and immunology in-dex were analyzed.Results Out of the 434 patients,26.26％ of the total subjects were anti-HEV IgG positive.The positivity of anti-HEV IgG in adults and the progress of vitiligo patients was higher than that of teenagers and stabilization of vitiligo patients,the difference was statistically significant(P<0.05).Compared to the normal cases of IgA,IgG,C4,the positivity of anti-HEV IgG was significantly higher in the abnormal cases,the difference was statistically significant(P<0.05).Those 10 cases who were anti-HEV IgM positive,were anti-HEV IgG positive also.Conclusion The infection status in patients with vitiligo is serious and effective prevention strategies are required in future for reducing HEV transmission in these patients in order to reduce the incidence.
