Using immunohistochemical method,the antigens were shown to be mainly located in the cecum,tegument,esophagus,pharynx,excretory bladder,uterus and oral sucker of Pagumogonimus skrjabini.Histochemical analyses showed that antigens contained enzymes such as acid phosphatase (ACP),alkaline phosphatase (AKP),and acetyleholinesterase (AChE).Other chemical substances,for example,alkaline protein,basic protein,glycogen and acid mucopolysaccharides were also detected in the antigens of P.skrjabini.

Objective To investigate the relationship between plasma homocysteine levels and lipids in aged patients with acute cerebral infarction(ACI).Methods Fourty-eight cases(observation group),who had been inpatients with cerebral infarction during May 2006 to May 2007,thirty healthy people(control group)contrasted and analyzed.Results The mean plasma homocysteine level and cholesterol(TC),triglycerides(TG),low density lipoprotein(LDL)of aged patients with acute cereral infarction were significantly,higher than those of the control group,but high density lipoprotein(HDL)was lower(P＜0.01).No significant correlation between Hcy level and TC,TG,HDL-C,LDL-C level in serum.Conclusion Plasma homocysteine lexrel and lipids all siginificantly increased in aged patients with acute cereral infarction,and homocysteinemia is not related with lipids,but is an independent risk factor for cerebral infarction.

ObjectiveLamiophlomis rotate is the rare perfumes Tibetan medicine.This article aimed to explore the current research of Lamiophlomis rotate on the base of literature.MethodsEstablish database of researching literature on Lamiophlomis rotate in domestic published between 2000 and 2010.Results Altogether 210 articles distributed in 112 kinds of journals were found.These articles involved with 8 areas of clinical research(113 article),pharmacological research(18 article),component analysis(35 article),preparation process (15 article),breed and cultivation of seeds (4 article),new drug testing (3 article),biological characteristics and drug economics.32 articles gained fimancial assistance from fund.Three articles on breed and cultivation of seeds gained financial assistance from fund,occupying 75.00％ of such research.Conclusion There were few articles published in core journals,besides relatively scattered distribution of researching institute and journals.Studies on breed and cultivation of seeds should be strengthened.

OBJECTIVE To evaluate the bioethical principles which should be followed in the epidemiological study of AIDS.METHODS Practicality of bioethical principles in epidemiological study of AIDS was evaluated by theoretical analysis method.RESULTS The important principles in the epidemiological study of AIDS are respect,beneficence/nonmaleficence and justice principles.CONCLUSIONS Following bioehical principle is the basis of epidemiological study of AIDS.

Objective To establish an acoustic perceptual method analyzing the compensatory articulation errors in children with operated cleft palate via the formants of Chinese pure vowels. Methods The first three formants which represent vocal transmission character in Chinese pure vowels of 84 subjects with operated cleft palate, were measured by Computerized Speech Signal Processing System (CSSPS). The Chinese vowel graph of postoperative patients with cleft palate was stated by the first formant frequencies (F1) and the second formant frequencies (F2) of the Chinese pure vowels between the two groups. Results Values of F1 and F2 of vowels except [a] in the poor articulation group (Group A) were significantly different from those in the good articulation group (Group B) (P<0.05 or P<0.01). As compared with that in Group B, the vowel graph demonstrated the decreased perceptual distances in Group A. These findings indicated that there might still be the backward movements of tongue, perverted mandibular movements and disharmonious lip movements in addition to the velopharyngeal insufficiency (VPI) in Group A. Conclusion The speech articulation of children with repaired cleft palate should be gained by correcting the aberrant compensatory articulation errors in the condition of velopharyngeal competence. Computerized Speech Signal Processing System (CSSPS), which is regarded as the content of objective quantitative measurement, is a precise, simple, reliable and atroumatic technique for children with cleft palate to analyze pathological compensatory articulation errors.

Objective This paper analyzes the situation of confidential blood discarding in voluntary blood donation in Jiaxing in 2011-2016 years,and provides scientific evidence for ensuring the blood safety.Methods During 2011-2016 years,15 voluntary blood donors who required confidential blood donation in the blood bank were investigated for their reasons and characteristics.Results The blood discarding rate was 0.011％.15 cases were abandoned in the confidential blood discarding of voluntary blood donation in Jiaxing,in which 14 blood donors' 4 infectious disease markers were negative,1 blood donor was HIV positive,18-30 years old unmarried males are the main category of secrecy abandoned blood donors,the number of secondary donors who have high-risk behaviors or diseases are relatively small.The causes of confidentiality were mainly high risk behaviors (27％) and feculent sexual history (20％).Conclusion Blood donors' conscience to report the truth is quite important to improve the safety of blood transfusion,it is a must to prepare the training of staffs,to broaden the back way,strengthen the propaganda and education,strengthen the consultation work before the blood donation and provide a private security environment of abandoned blood for blood donors.

Analysised the transmission routes of AIDS in hospital,preventive strategies and existing ethic problems.Putting forward the importance of respecting the proper right of AIDS patients and health care workers in the prevention of nosocomial-transmitted HIV.On the basis of scientific study,strengthening the propagating of the knowledge of AIDS in the whole society,respecting the right and statue of AIDS prevention and timely treatment among both patients and health care workers.Respecting their medical treatment right and secrets,detecting HIV of patients on the informed consent.Respecting health care workers' right,providing profession guide and preventive strategies for prevention and control of nosocomial-transmitted AIDS.

Objective To explore the improvement of minocycline on negative symptoms in patients with schizophrenia and its influence on tumor necrosis factor (TNF)-α.Methods Patients with schizophrenia were randomly assigned into two groups.One was olanzapine combined with placebo group (control group, 37 cases).The other was olanzapine combined with minocycline group (treatment group, 200 mg ·d-1,po,bid, 38 cases).Both groups were assessed by the positive and negative syndrome scale (PANSS), the scale for the assessment of negative symptoms (SANS), and also tested the level of TNF-α before and after 12 weeks treatments.Results After 12 weeks treatments, the scores of SANS and PANSS in treatment group were significantly lower than those of control group (P<0.05).The level of TNF-α in treatment group[(6.5±1.3) pg ·mL-1]was significantly lower than that of control group[(7.6±1.8) pg ·mL-1] (P<0.01).Conclusion Minocycline can improve negative symptoms in patients with schizophrenia, and the mechanism may be related to lower the level of TNF-α.

Objective This study was designed to determine the serum CA-Hb 3 level in human colorectal carcinoma and analyze its clinical significance.Methods The level of serum CA-Hb 3 was measured by ELISA in 72 patients with colorectal carcinoma and 36 normal persons as the control group.Results The level of serum CA-Hb 3 in colorectal carcinoma was significantly higher than that of normal control .The level of serum CA-Hb 3 was positively related with tumor size,clinical pathological staging.With progression of clinical pathological staging (Dukes'stage),the level of CA-Hb 3 increased significantly,but its relation to tumor size,age,and sex was not significant.Conclusion Serum CA-Hb 3 assay may be a potentially valuable marker in assessment of pathological staging and judgement of clinical prognosis of colorectal carcinoma.
