The self-designed experimental teaching method is introduced in detail in this paper,including the preparative work before class,discussion of experimental designing proposal,and accomplishment of specific experiment and so on.The teaching method innovations on pathophysiology experiment are very helpful to cultivate the students' ability to solve practical problem and lay the foundation to cultivate talented medical science personal.

To compare and analyze the clinical treatment effect of primary pterygium with amniotic membrane transplantation, autologous corneal limbus stem cell transplantation and intraoperative application of 0. 2g/L mitomycin C.METHODS: Retrospective analysis of 232 patients who were underwent primary pterygium surgery was performed. Eighty-two cases were treated with amniotic membrane transplantation, 90 with autologous corneal limbus stem cell transplantation, and 60 with intraoperative application of 0. 2g/L mitomycin C. The postoperative recurrence and complications of three operative methods were compared.RESULTS: The recurrence rate of autologous corneal limbus stem cell transplantation and intraoperative application of 0. 2g/L mitomycin C was lower than that of amniotic membrane transplantation ( P < 0. 05 ). The recurrence rate between autologous corneal limbus stem cell transplantation and intraoperative application of 0. 2g/L mitomycin C had no difference ( P > 0. 05 ). Corneal epithelium defect, tears and photophobia were higher in 0.2g/L mitomycin C group (P<0. 05), which were no statistical difference between autologous corneal limbus stem cell transplantation and amniotic membrane transplantation (P>0. 05). Conjunctival congestion and subconjunctival hemorrhage in three groups had no statistical difference (P>0. 05).CONCLUSlON: Compared with other two operative methods, autologous corneal limbus stem cell transplantation for primary pterygium has the advantages of lower recurrence rate and less complications.

AIM:To observe the changes of macular thickness in patients after cataract operation.
METHODS: A total of 126 patients ( 133 eyes ) were divided into two groups that were included in this study. The group (68 eyes of 64 case) with phacoemulsification combined intraocular lens implantation and ( 65 eyes of 62 cases ) with manual small incision cataract surgery ( MSICS) . There was no complication before and during the surgery. Optical coherence tomography ( OCT) was examined 1, 3mo before and after surgery. The visual acuity and macular thickness were compared after surgery. The SPSS 17. 0 software was used for statistical analysis. The paired t-test was used before and after surgery. Independent-samples t test was used in two groups before and after surgery,α=0. 05.
RESULTS: The cataract phacoemulsification group:preoperative and 1mo after surgery, the mean macular thickness was 241. 3±10. 9μm and 279. 7±16. 5μm, with significant difference ( P < 0. 01 ). The mean macular thickness was 245. 6±12. 6μm 3mo after surgery without statistical difference compared with preoperative ( P>0-05). The mean macular thickness was 279. 7±16. 5μm 1mo after surgery and 245. 6±12. 6μm 3mo after surgery with statistical difference(P<0. 05). Three eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes of them was resolved 3mo after surgery. The group of MSICS: preoperative and 1mo after surgery, the mean macular thickness was 240-5±11. 9μm and 280. 7±16. 8μm, with significant difference (P<0. 01). The mean macular thickness was 246. 6±13. 2μm 3mo after surgery without statistical difference compared with preoperative ( P >0-05). One month after surgery and 3mo after surgery, the mean macular thickness were 280. 7±16. 8μm and 246-6±13. 2μm, with statistical difference (P<0. 05). Two eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes were resolved 3mo after surgery. Between the two groups pre-operation or after operation for 1, 3mo respectively P values were without statistical difference (P>0. 05).
CONCLUSION: The macular thickness and macular edema can be found 1mo after cataract phacoemulsification and MSICS. Three months post-operatively, macular edema disappears and does not show statistical difference compared with preoperative. The increase of macular thickness has no obvious relationship with the choice of surgery.

BACKGROUND: It has been recognized that the traditional herbal treatment and daoyin exercises(physical and breathing exercise) can relieve the symptoms such as tiredness of cancer patients and strengthen the tolerance to chemical drugs. But the criterion of quantitative evaluation for the effect should be scientific.OBJECTIVE: To evaluate the influence of Chinese herb for strengthening the body resistance and daoyin exercises on the survival state of lung cancer patients with the evaluation scale of life quality.DESIGN: Non-randomized and concurrent controlled trial.SETTING: Department of Integrated Traditional Chinese and Western Medicine, Clinical Cancer Research Center, Guangzhou Medical College;Zhaoqing First People's Hospital.PARTICIPANTS: Totally 60 inpatients of the Department of Integrated Traditional Chinese and Western Medicine of Clinical Cancer Research Center of Guangzhou Medical College were enrolled from October 1997 to March 2001 in the study. All of them were volunteers. There were 41 males and 19 females, 30 patients in the treatment group and 30 in the control group.METHODS: The treatment group was given chemical therapy, at the same time, the herbal treatment and daoyin exercises. The control group was given chemical therapy only. The same chemical therapy was applied to both groups. The appointed doctor familiar with the evaluation table of quality of life was responsible for evaluating the quality of life of the patients in the two groups before and after treatment and the observation of their accomplishment of chemical therapy. The evaluation table of quality of life of Chinese lung cancer patients was used in the evaluation. The table included 5 factors: the physiological state caused by lung cancer, social/family state, relation of altitude towards doctor and disease, emotional state, and functional state. The statistical analysis was done to see the accomplishment of chemical therapy of two groups.chemical therapy of the two groups.RESULTS: According to the intention-to-treat analysis, 60 patients all completed the whole process of study. The comparison of the score before physiological state after treatment was obviously lower than that before treatment[ (14. 1 ± 3.2), (31.7 ±2.9) scores, P ＜ 0.01] and of control state was obviously higher than that before treatment[(25.2±3.1),(12.2 ±2.3)scores, P ＜0.01] and of control group[(19.1 ±2.2) scores,after treatment was obviously higher than that before treatment[ (37.4 ± 5.2),(24.2 ±3.5) scores, P ＜0. 01 ]and of control group[ (29. 1 ±3.4)scores, P before treatment[ (43.8 ± 5.6), (28.5 ± 4. 7) scores, P ＜ 0. 01 ] and of tional state after treatment was obviously higher than that of before treatment [(26.3±2.3), (17.3±3.3) scores, P ＜ 0.01] and of control group [ (20. 3 ± 1.1) scores, P ＜ 0. 05] . The accomplishment rate of chemical control group, 26 patients accomplished 1 course(87%, 26/30) and 18rate of 2 courses of chemical therapy of treatment group was obviously higher than that of control group ( P ＜ 0.05 ).CONCLUSION: The herbal treatment combined with daoyin exercises can improve the tolerance of lung cancer patients for chemical therapy and relieve the symptoms, thus improving their quality of life.

The authors think the problems at present in clinical slimming treatment of acupuncture and moxibustion, such as the effect and the mechanism of slimming, local slimming and the rebounding of body weight after slimming therapy, etc.. Holding that acupuncture and moxibustion slimming therapy has a certain therapeutic effect, acupuncture and moxibustion treatment combined with proper control of diet, sports and other methods can increase the effect of reduction of body weight; and regulation of the satiety center, inhibition of excessive appetite and mobilization of decomposition of lipids are an ideal program for acupuncture and moxibustion slimming treatment; local slimming treatment should be conducted on the basis of general slimming treatment; regulation of the satiety center, scientific combination of diet and proper sports are a tactic for prevention from rebounding of body weight after slimming treatment.
