Medical has the dual attributes essentially , which is not only a science but also a humanology . Therefore , it needs to be nourished by rich humanistic spirit .At present , the generalization of medical technology , the abnormal development of medicine socialization and the less care from humanities to medical and many other reasons lead to the lack of humanistic spirit of medicine .To correct the phenomenon of the disorder, we should explore the effective means actively to provide powerful support for the returning of the medical humanism .There-fore, using an appropriate method to strengthen the humanities education of medical students and attention in the classroom will be regarded as good path in medical humanities spirit returning .

AlM: To explore clinical efficacy of hyperosmotic glucose after cataract surgery.METHODS: Eighty eyes ( 80 cases ) with ll level and above grades corneal edema after small incision cataract operation were enrolled. They were randomly divided into treatment group and control group. Control group used TobraDex eye drops and other conventional treatment and the treatment group received hyperosmotic glucose(500g/L) with the bases of the control group. The regression of corneal edema was observed by slit lamp microscope. SPSS 17. 0 statistical software was used for statistical analysis.RESULTS: The level of corneal edema at the first day after surgery, age, sexuality and nuclear hardness in the treated group were compared with those in the control group, the differences were without significances ( P>0. 05). Disappearance time of corneal edema was 4. 95 ± 3. 62d of the treatment group, and was 6. 80±3. 33d of the control group, the treatment group was better than control group (t=8. 55, P=0. 00).CONCLUSlON: Hyperosmotic glucose has exact and obvious efficacy for early corneal edema after cataract surgery.

AIM: To investigate clinical effects of local resection of eyelid tumors and pathological examination or frozen section examination as well as the stage I recovery.
METHODS: For all 92 cases 92 eyes of eyelid tumor patients who underwent local resection, reconstruction in stage Ⅰ and routine pathological examination ( 37 cases of suspected malignant tumors using frozen section examination. If it was malignant, excision by Moths surgery) . Using free palate mucosa autograft in stage I or reconstruction by Hughes surgery combined with eye flaps repaired eyelid defects.
RESULTS: The postoperative pathological diagnosis:52 cases were benign tumors, and 40 cases malignant tumors. All cases of eye flaps and hard palate mucosa grafts were survived. Followed up for more than 6mo, no tumor were recurred. The appearance and function of eyelid were satisfactory.
CONCLUSION: In this group of cases, nearly half of eyelid tumors are malignant tumors. It should be treated and operated as early as possible. For suspected malignant tumors, we use frozen section examination to confirm its properties in order to excision cleanly in stageⅠ, reducing the recurrence and metastasis. According to the eyelid defect after resection, we could do repair operation in stage Ⅰ. The inner larger defect is repaired by using hard palate mucosa transplantation or Hughes surgery. The outer layer of the eyelid defect is repaired by using eye flap glide, the free flap, the kite flap, the simple suture, etc. It should be careful when using the hard palate mucosa transplantation in the upper eyelid defect.

Objective To evaluate the efficacy of endovenous laser treatment(EVLT) in the treatment of varicose veins in lower limbs. Methods A total of 450 cases of varicose veins in lower limbs(606 limbs) received EVLT with 940 nm diode laser under a continuous mode from October 2003 to February 2006.All the patients were evaluated with color ultrasonography after the operation.Results The follow-up duration was 2～29 months(mean,16 months).Satisfactory effects were achieved in XXX cases,with varicose veins subsided and sense of swelling and heaviness significantly relieved.In 49 cases accompanying active ulcers before operation,the ulcer healed within 10 days after operation in 44 cases and within 16 days in 5 cases.Five cases experiencing a heat injury were dismissed from hospital on the 7th day after operation.Conclusions EVLT is a minimally invasive operation possessing safety,simple performance,and effectiveness,and without leaving any scar.It is an ideal method in the treatment of varicose veins of lower limbs.

Objective:To evaluate the in vitro release behavior of doxorubicin(Dox)-loaded microspheres and the stability of Dox during encapsulation process and in vitro release.Methods: Dox-loaded microspheres were prepared by double emulsion(W/O/W) method with poly(lactic-co-glycolic acid)(PLGA) as the carrier material.The physical and chemical characteristics of microspheres,including the mean diameter,morphology,drug entrapment efficiency and loading rate,were evaluated.The in vitro release behavior and its influencing factors were determined by ultraviolet spectrophotometry.Dox stability was evaluated by HPLC method during the encapsulation process and in vitro release.Results: The prepared microspheres had a complete spheric shape and dispersive quality.The mean diameter of the microspheres was 85 ?m;the drug entrapment efficiency was 95.1%;and the loading rate was 14.8%.Releasing rate of the microspheres slowed down with the increase of PLGA concentration and the decrease of W/O value.The encapsulation process had no obvious effect on the stability of Dox,while Dox degraded during in vitro release as the prolongation of time.On day 10,the peak area of degraded material accounted for 2.46%.Conclusion: Dox can be encapsulated in the microspheres by double emulsion method and different release rates of Dox can be achieved by adjusting PLGA concentration and W/O volume ratio.

BACKGROUND: Advanced oxidation protein products (AOPPs) are a crucial pathogenic link to such long-term uremic complications in hemodialysis patients as immune system dysregulation, accelerated atherosclerosis, dialysis-related amyloldosis and so on. However, basic studies on AOPPs are relatively few, and one of the main reasons is the fact that it is difficult to obtain AOPPs with high pudty and biological activity.OBJECTIVE: To prepare, pudfy and indentify AOPPs, with the hope of searching for a method of preparing AOPPs with high purity and biological activity.DESIGN, TIME AND SETTING: A single sample observation was completed in the Clinical Biochemistry Section of Ecsomatics Department, Third Military Medical University of Chinese PLA from September to November in 2008. MATERIALS: Human serum albumin (HSA) was provided by Chengdu Rongsheng Company Ltd. Hitrap 26/60 sephacryl S-300 was purchased from GE Healthcare.METHODS: Hypochloric acid was used in the oxidation of purified HSA to prepare in vitro the AOPPs-modified HSA (AOPPs-HSA), which was then isolated by Hitrap 26/60 sephacryl S-300. Relative molecular mass was determined by sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE), native polyacrylamide gel electrophoresis (PAGE) and molecular weight standards. Structural features and biological activities were identified in the experiment of tumor necrosis factor α (TNF-α) release from monocytes.MAIN OUTCOME MEASURES: ①The purification and gel electrophoresis results of HSA. ②The purification and gel electrophoresis results of AOPPs. ③The dose-effect relationship between AOPPs-HSA and TNF-α release from monocytes. RESULTS: The relative molecular mass of AOPPs-HSA was 670 000 according to SDS-PAGE, native PAGE and molecular weight standards. Moreover, AOPPs-HSA could encourage the release of TNF-α from monocytes. The time effects showed that TNF-α release volume significantly increased after 6 hours of stimulation by AOPPs-HSA (1 g/L) and reached a peak at hour 12. CONCLUSION: Highly purified and bioactive AOPPs can be successfully prepared by the above-mentioned method, which builds a basis for further study on AOPPs.

Objective To investigate the serum cystatin C (CysC) level and explore its relationship with cytokines and atherosclerosis (AS) in maintenance hemodialysis (MHD) patients.Methods A total of 110 stable MHD patients undergoing hemodialysis for at least six months and 60 healthy control people were enrolled in the study.Serum levels of CysC and high-sensitivity Creactive protein (hsCRP) were measured by immunoturbidimetry.The serum levels of total homocysteine (tHcy),IL-1β,IL-6 and TNF-α were determined by ELISA.Prevalence of atherosclerosis was detected by carotid ultrasonography.The relationship of CysC level and cardiac geometry incidence in MHD patients was analyzed by Logistic regression model.Results The serum CysC level was significantly higher in MHD patients as compared with healthy controls [(6.19±0.95) mg/L vs (0.76±0.21) mg/L,P＜0.01],and the serum levels of hsCRP,tHcy,IL-1β,IL-6,TNF-α were significantly higher in MHD patients than those in healthy control group (P＜0.05 or P＜0.01).The serum CysC level was higher in MHD patients with carotid artery atherosclerosis compared to patients without carotid artery atherosclerosis (P＜0.05).CysC was positively correlated with hsCRP,tHcy,IL-1β,IL-6,TNF-α respectively (P＜0.05 or P＜O.01),and was positively correlated with carotid intimal medial thickness (IMT) and AS.Besides,a negative correlation was found between the serum CysC level and the serum albumin level (P＜0.05),while CysC was positively correlated with dialysis duration,systolic pressure and iPTH (P ＜0.05).Conclusion Serum CysC level is significantly higher in MHD patients and is correlated with hsCRP,tHcy,IL-1β,IL-6,TNF-α as well as carotid artery atherosclerosis,which indicates that CysC is an independent risk factor of AS in MHD patients.
