This review snmmarized and estimated the management of cataract blindness in China recently,and introduced the purport of clinic medical economics.Based on it,it was proposed that our service system of cataract blindness could use the experiences of other countries as reference and engaged in more investigations in search of Chinese way for cataract blindness.

Objective To investigate the correlation between the expression of human leukocyte antigen B27(HLA-B27)antigen and ankylosing spondylitis(AS),and its implications for the diagnosis and differential diagnosis of AS.Methods Flow cytometry was used to detect HLA-B27.354 suspected AS patients,35 patients final diagnosed with AS and 30 patients diagnosed with rheu-matoid arthritis(RA)were enrolled in the study.Results The positive rate of HLA-B27 in 354 patients with suspected AS was 22.0%,in patients diagnosed with AS was 85.7%,which was higher than the RA group(P <0.05).In AS patients,Males accoun-ted for 77.1%,females accounted for 22.9%,and the patients′age mainly concentrated in youth.The sensitivity and specificity of HLA-B27 test was 85.7% and 100.0% respectively in the diagnosis of AS.Conclusion HLA-B27 antigen detection is important for early diagnosis and differential diagnosis of AS patients.

Objective To investigate the causes,diagnostic methods,prevention and cure of postmenopausal bleeding(PMB).Methods The clinical and pathological data of 210 PMB patients admitted in this hospital were retrospectively analyzed.Results The causes for PMB were benign diseases(69.5%),the most of which were infec- tious diseases(49.5%),non-organic disease(20.5%)and malignant tumor(10.0%).Compared with benign diseases and non-organic diseases,the attack age of malignant tumor was higher[(67.1?6.9)years old],menopausal dura- tion was longer(11.6?2.9)years,bleeding duration was longer[(157.6?26.4)days],and mucous membrane was obviously thickened[(14.6?3.2)mm](P0.05).Conclusion The main cause for PMB is benign diseases,followed by non-organic diseases.More attentions should be paid to the PMB patients with higher attack age,longer menopausal duration and bleeding dura- tion,and obviously thickened mucous membrane,so as to be precautions to the occurrence of malignant tumor.

Objective To investigate the effect of different stimulating culture conditions and detecting methods on the frequency of Th17 cells and to set up and optimize the experimental method for detecting the frequencies of human Th 17 cells in peripheral blood by flow cytometry (FCM ) .Methods The peripheral blood in the healthy people was performed the stimulating culture by phorbol myristate acetate (PMA) at different final concentrations(50 ,100 ,150 ,200 ,250 ,300 ng/mL) and ionomycin 1 μg/mL .The frequencies of Th17 cells were assessed by FCM after different stimulating time points (4 ,6 ,8 ,10 ,12 h) .The mean fluorescence in-tensity(MFI) and percentage of the ratio of CD4 positive cells on the cellular surface and inside cell membrane were measured be-fore and after PMA stimulation .Results The frequency of Th17 cells was highest with the good stimulation effect under the condi-tion of PMA 150 ng/mL and ionomycin1μg/mL stimulation for 6 h (P<0 .05) .MFI of CD4 inside cellular membrane after stimula-tion was lower than that in the cells with stimulation after labeling membrane surface CD 4(P<0 .05) ,and the Th17 cell frequencies and the ratio of CD4 positive cells were higher than those in the latter ,but the differences were not statistically significant (P>0 .05) .Conclusion After stimulating whole blood with the final concentration of PMA 150ng/mL and ionomycin1μg/mL for 6 h , measuring intracytoplasm CD4 and IL-17 levels is the simple and effective method for detecting the frequency of human Th 17 cells .

Objective To investigate the dynamic variation of flavonoids contents in the flowers of Citrus grandis at different flowering periods. Methods The content of total flavonoids in the flowers of Citrus grandis was determined by means of ultraviolet-visible absorption spectroscopy ,and the contents of naringin and rhoifolin were determined by HPLC. Results The content of total flavonoids in the flowers during the flower withering period ,the young fruit period ,the blossom period,and the budding period was 306.90 mg.g-1,277.93 mg.g-1,215.55 mg.g-1 and 162.74 mg.g-1 respectively. The naringin content during the above four different periods was 246.31 mg.g-1,213.93 mg.g-1,175.94 mg.g-1 and 130.90 mg.g-1 respectively. The rhoifolin content during the four periods was unchanged. Conclusion The contents of total flavonoids and naringin in flowers of Citrus grandis during flower withering period are the highest.

Objective To explore the function of intensive care unit (ICU) in earthquake disaster. Mothod ICU in tent set by doctors from Second Military Medical University and Sichuan Jiangyou People's Hospital in 5·12 Wenchuan earthquake disaster. The value of ICU in tent was estimated by retrospective analysis of the experi-ence of emergency treatment for the critical injuries. Results Inside ICU in tent,there were many critical patients successfully rescued, including a soldier with septic shock, a casualty with traumatic shock during aftershock, a middle school student with crush injury and cornpartment syndrone, a peasant trapped under mined buildings for 168 hours with capillary leak syndrome, and a traffic victim and an aged patient with cardiac arrest. Patients after replatation of severed limb and patients after thoracic operation were monitored. Teaching rounds in the wards and logistics health drilling were made as well. Conclusions ICU in tent as a place where the critical casualties and patients after major operations could be rescued,cared for and monitored successfully,as well as the venue of teach-ing activity and logistics health drilling.

Objective To investigate the pathological diagnosis of high-grade intraepithelial neoplasia in gastric biopsy.MethodsOne hundred and forty-three cases diagnosed by gastric biopsy as high-grade intraepithelial neoplasia were analyzed by light microscopy,and were compared with the pathological findings of surgical specimens in 60 cases and a second biopsy in 13 cases.Results Among the sixty cases treated surgically following the gastric biopsies,no carcinoma was found in 6,while the other 54 were diagnosed as gastric adenocarcinoma,27 in advanced stage and 27 in early stage,respectively.Fifteen cases were well-differentiated,24 moderately-differentiated,12 poorly-differentiated and 3 were of mucinous type.Four of the 13 cases with a second biopsy were diagnosed as well-differentiated adenocarcinoma,8 low-grade intraepithelial neoplasia and 1 chronic inflammation.The colorectal adenomas-like changes were morphologically found in 6 surgically-treated cases without carcinoma,5 of whom mucous muscles were not found by biopsy.Fibroblastic reactions were found in 9 cases,all of which were diagnosed as adenocarcinoma in surgical specimens.Conclusion Ninety percent of the cases who are diagnosed as high-grade intraepithelial neoplasia by biopsy may have already been complicated with adenocarcinoma.The location and depth of the specimen in gastric biopsy have a considerable influence on pathological diagnosis.The fibroblastic reaction may be considered as an important marker for gastric adenocarcinoma in pathological diagnosis of gastric biopsy.

ObjectiveTo investigate sleep disorder of patients with depression and find out the regularity.Methods78 depression cases in the east-region of Shenyang were evaluated by Pittsburgh Sleep Quality Index (PSQI) questionnaire and mental health symptom checklist-90 (SCL-90). The results were contrasted with normal control group.Results63 depression cases (80%) had sleep disorder (PSQI scores≥8) and were significantly higher than normal control group. The PSQI evaluation showed that sleep quality, enter-sleep time, sleep efficiency, sleep disorder, hypnotige drugs, function of daytime and total scores of PSQI of the depression group were significantly higher than that of normal control group (P<0.05～0.01). The SCL-90 test showed that scores of somatic, obsessive, depressive, anxiety, phobia, paranoid and mental-illness, etc. and total quota of bad-sleep quality group were significantly higher than that of the fine-sleep quality group (P<0.05～0.01).ConclusionDepression patients have significantly descent in sleep quality, latter is often closely related to the mental psychotic expressiveness of somatic, obsession, depression, anxiety, phobia, etc.
