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.

Objective To study and assess clinical application of two Nickel-Titanium(NiTi)rotary instru- ments,namely ProTaper and Hero 642,in preparation of root canals.Methods 125 teeth were divided into three groups and respectively instrumented by stainless K-files,ProTaper or Hero 642 rotary instruments.All teeth were obturated with lateral condensation method.The efficiency of preparation and obturation was analyzed with radio- graphs.Results NiTi rotary instruments were better in keeping the curvature and flow of curved canals than stain- less K files.There was no transportation,apical blockage and ledge in NiTi groups.The operative time was shorter and endodontic flare-up seldom occurred in NiTi groups.Conclusion The NiTi rotary instrumentation technique could be used to prepare curved root canals effectively and quickly.The future use of NiTi engine-driven rotary in- strument appeared to be promising.

METHODS: The model of diabetic rat was induced by strepotozotocin. The animals were randomly divided into six groups:TMN minimal dose group, TMN mild moderate dose group, TMN maximal dose group, methycobal group, model group and normal control group. All TMN groups were treated with TMN Granule through tube feeding (2.95 g/kg、5.90g/kg、11.80g/kg). Methycobal group was treated with methycobal tablets through tube feeding (0.14mg/kg). The duration of treatment was 3 weeks. The caudal nerve conduction velocity, RBC S content were investigated before and after treatment. RESULTS: It showed that TMN Granule could increase the caudal nerve conduction velocity significantly in the maximal dose group and the mild moderate dose gorup ( P

Objective To explore the thyroid function changes of episodes period and remissions period in children with primary nephrotic syndrome (NS).Methods The urinary protein quantitation and serum albumin,total cholesterol,thyroid hormone level [total triiodothyronine (TT3),total thyroxine (TT4),free triiodothyronine (FT3),free thyroxine (FT4) and thyroid stimulating hormone (TSH)] of episodes period and remissions period in 15 children with primary NS were retrospectively analyzed.Results There were statistical differences in urinary protein quantitation and serum albumin,total cholesterol in children with NS between episodes period and remissions period (P ＜ 0.05).The TT3,TT4,FT3,FT4 in episodes period were significantly lower than those in remissions period [(0.6 ± 0.3) μ g/L vs.(1.3 ± 0.3) μ g/L,(40.0 ± 23.0)μ g/L vs.(68.0 ± 15.0) μ g/L,(1.6 ± 0.3) pmol/L vs.(3.3 ± 0.3) pmol/L,(8.6 ± 2.5) pmol/L vs.(12.2 ± 2.0) pmol/L],TSH was significantly higher than that in remissions period [(5.6 ± 2.1) mU/L vs.(2.5 ± 1.1) mU/L],there were statistical differences (P ＜ 0.05).Conclusions Thyroid function of episodes period in children with primary NS is decreased temporarily,associated with heavy proteinuria leads to thyroid hormone missing from urine.Detecting thyroid function plays an important role in estimating the state and guiding the treatment of primary NS.

Objective To observe the effect of exhaustive exercise on the function of the kidney in rats and explore the mechanism. Methods Fourteen male Sprague-Dawley rats were divided into sedentary control group (group C) and exhaustive exercise group (group E). They were measured the urine protein, uric acid, glucose, and blood urea nitrogen after exercise. The reactive oxygen species, inducible ni-tric oxide synthase, nitro tyrosine in kidney, and nephrin protein in the kidney were detected with fluorescent probe and Western blotting, re-spectively, and observed under Harris staining. Results There were significant differences between groups C and E in urine protein, uric ac-id, glucose, blood urea nitrogen, reactive oxygen species, inducible nitric oxide synthase, nitrotyrosine and nephrin protein (P<0.05). The glomerular morphology and the deformation of capillary basement membrane were found under the fluorescence microscope in group E. Conclusion Exhaustive exercise may damage the structure of kidney in rats, which may associate with oxidative stress.
