Objective To observe the effects of different doses of dexmedetomidine combined with ropiva-caine for ultrasound-guided fascia iliaca compartment block on postoperative analgesia and rehabilitation in patients undergoing total hip replacement surgery. Methods 80 patients with ASAⅠ~Ⅱundergoing total hip arthroplasty were ramdonly divided into 4 groups. Records of patients with ultrasound guided fascia iliaca compartment block onset time,block fading time,VAS at 4 h,8 h,12 h,24 h,48 h;duration of operation,intraoperative remifent-anil and propofol requirement;24 h and 48h of sufentanil use;after the operation were recorded for the first time , ambulation time,hospitalization time and observe whether bradycardia,intraoperative awareness and other adverse reactions. Results Compared with group A and B,the onset time of C were shorter(P<0.05);the VAS was less (P<0.05);the remifentanil equirement was significantly was reduced(P<0.05);the amount of sufentanil after operation 24 h and 48 h was reduced(P<0.05);the first time out of bed time and total hospitalization time was shorter(P < 0.05);patient satisfaction increased(P < 0.05);The extubation time was significantly longer and the occurrences of tachycardia were significantly increased in group D compared to other groups respectively. Conclusion 1.0μg/kg dexmedetomidine combined with 0.3%ropivacaine ultrasound-guided fascia iliaca compart-ment block can provide better postoperative analgesic and recover rapidly with fewer side effects in total hip replace-ment surgery.

Objective To observe the effect of 2,3,5,4'-tetrahydroxy stilbene-2-?-D-glycoside (TSG)on learning and memory and free radicals metabolism in mice with dementia induced by ?-amyloid(A?).Methods The mice models were established by injection of A?1-40 into the right lateral ventricle,and the treatment group was administered with TSG for 8 weeks by gastrogavage.Morris water maze and step-through test were performed in all the mice and then the mice were killed and radioimmunoassay was used to detect the content of interleukin-6(IL-6).Results The learning and memory in model mice were worse and the cortical IL-6 content increased compared to the normal control mice.TSG improved the learning and memory of A?-induced model mice and reduced cortical IL-6 content.Conclusion TSG could improve the learning and memory of dementia mice and decrease cortical IL-6 content,indicating a promising prospect in the treatment of dementia disease such as Alzheimer's disease.

Objective To evaluate the application of M2A capsule endoscopies ( CE) in the diagnosis of digestive tract diseases. Methods Forty - five patients (26 males, 19 females) , suffered from gastrointestinal bleeding, abdominal pain or chronic diarrhea were referred to this study and underwent capsule endoscopies. Their average age was 47. 8 years old (a range of 15 - 78). Capsule endoscopies were performed with the Given M2A video capsule system. The conventional diagnostic procedures (including small bowel radiograph, gastroenteroscopy, colonoscopy, etc. ) were done in 31 patients before or after the CE, thus the results of both procedures were compared. Results Among 45 patients, 44 have completed CE successfully. Any complication never experienced. The quality of photos was excellent. The significant pathological findings were revealed in 37 patients, diagnostic yield was therefore 84. 1% . Patients with esophagogastric diseases, small bowel diseases and colon diseases were found in 5,29 and 3 cases respectively. Thirty -one patients received a conventional diagnostic procedure before or after CE. Twenty one of them suffered from GI bleeding, pathological changes were found in 17 patients by capsule endoscopies, only 4 patients by conventional procedure; five of them suffered from abdominal pain, pathological changes were found in 5 patients by CE, only 2 patients by conventional procedure; 4 of them suffered from chronic diarrhea, pathological changes were found in 4 patients by CE, only 1 patient by conventional procedure. The pathological sites located by CE were quite similar to those by conventional diagnostic work-up. Conclusion CE has the advantages of high safety, excellent visualization and precise localization. Its efficiency in diagnosis is much better than that of conventional procedure, and is indispensable in the diagnosis of digestive tract diseases.

Objective To investigate the therapeutic effects of intravenous gammaglobulin (IVIG) on septicemia in premature infants.Methods The level of sero-IgG was observed in 20 septicemic premature infants before and after IVIG treatment,compared with those of 20 cases without IVIG treatment as controls.Results After IVIG treatment,the level of sero-IgG was remarkably higher than those before IVIG treatment and controls.Conclusion It is suggested that IVIG is safe and effective for treatment of septicemia in premature infants.

ObjectiveTo observe the effect of 2,3,5,4'-tetrahydroxy stilbene-2-β-D-glycoside(TSG) on learning and memory ability and free radicals metabolism in dementia model mice induced by β-amyloid (Aβ).MethodsAβ1-40 was given to the right lateral ventricle in the model group, and the TSG had been administered to the therapy group for 8 weeks by gastrogavage.All the mice of different groups were tested with Morris water maze and step-through test. Then the mice were killed and biochemical assays of neurol MDA,MAO-B,T-AOC were performed.ResultsThe model mice showed worse ability in learning and memory compared with control mice. The MDA cotent, MAO-B activity in the cortical increased in model mice compared with normal control; TSG reduced the MDA content, MAO-B activity,and increased T-AOC activity.ConclusionTSG can improve the learning and memory ability of model mice, decrease peroxidation level of brain, and increase antioxidation ability of brain, which suggest that TSG may have a promising application in treatment of dementia disease such as AD.

In healthy control group(group A),impaired fasting glucose group (group B) and diabetes group(group C),serum ferritin levels gradually raised[(170.7±91.8),(255.2±161.9) and (362.8±298.5) μmol/L].Hemoglobin Was elevated in impaired fasting glucose group,while returned to normal or even lower in diabetes group[group A(141.0±9.5),group B(148.2±11.2),group C(132.3±19.2)g/L].There was no difference in high sensitivity C-reactive protein among the groups.

According to the experience of teaching the science of Chinese Medical Herbs Preparation,the author gives some advice such as choosing typical drugs,providing examples and setting up comprehensive and contriving experiments etc,which is worth referring to in teaching es-pecially for those who have less time in experiments.

Background and purpose:Physical and psychological trauma has been a challenge for both clinician and patients with breast cancer after modified radical mastectomy,and now more and more patients have begun to accept breast reconstruction,especially Ⅰ stage reconstruction after surgery.The aim of our study was to investigate a breast reconstruction procedure that can not only achieve radical tumor excision but also retain the aesthetic appearance of breast.Methods:15 patients from January 2006 to April 2007 were enrolled with early stage breast cancer have received surgical treatment with conservation of breast skin,breast tissue excision and axillary lymph nodes;latissimus dorsi muscle flap has been used for breast reconstruction.Results:The results of the 15 cases:excellent in 11 cases(83.3%),good in four cases(16.7%).Conclusions:Immediate breast reconstruction after radical mastectomy with conservation of skin has shown good results in terms of aesthetic appearance of breast,this procedure has been proved to be a safe and feasible method of treatment for the patients with early stage breast cancer.

Objective To understand the need on AIDS related knowledge and its awareness level on the part of migrants,a special group of people,in north Anhui where there is a high incidence of AIDS,so as to provide basis for making AIDS intervention measures aimed at the group.Methods In the two towns of Linquan County in Anhui,four villages comparatively far away from each other were extracted at random in the unit of village,totally 552 migrants,were surveyed with the self-designed questionnaires.Results Among the 552 research subjects,457 male migrants and 95 female migrants,the female were lower(P
