Objective To analyze the surgical treatment choice of hepatolithiasis and its curative effect. Methods The clinical data of 120 patients with hepatolithiasis admitted in our hospital were randomly selected and retrospectively analyzed. 43 cases were undergone cho-ledocholithotomy, 37 cases were given merotomy of live, 31 cases were given hepatic duct plasty and choledochojejunostomy, and 9 cases were performed fiber choledochoscope lithotomy. Results All the 120 cases were followed-up from 1 year to 10 years. The postoperative re-sidual stone rate, good rate, and occurrence rate of complications were respectively:42. 23%, 78. 69%, 9. 23% in group of choledocho-lithotomy;8. 05%, 95. 93%, 18. 09% in group of merotomy of live;13. 33%, 87. 33%, 21. 32% in group of hepatic duct plasty and cho-ledochojejunostomy;31. 98%, 78. 04%, 15. 69% in group of fiber choledochoscope lithotomy. The total residual stone rate was 24. 17%, the total good rate was 85. 83%, and the occurrence rate of complications was 15. 83%. Conclusion Choose the suitable operation method according to medical history of patients is the the key to reduce the residual stone rate and the occurrence rate of complications, thus elevating therapeutic efficacy of hepatolithiasis.

The professionalism view of qualified person and some reasonable proposals for the promotion of the professionalism are put forward. The necessity of the professionalization of qualified person and the effective measures of perfecting the professionalization are studied by the comparative analysis between home and abroad combined with the game model analysis. Under the current national conditions, qualified person are repositioned, and after learning the advanced experience of the EU, the registration system is strictly carried out, which can promote the professionalism of qualified person and make relevant measures in order to restrict the behavior of qualified person.

Objective To explore whether ganoderma spores could help the neural epithelial cell of embryonic neural tube stagnated by retinoic acid in G-0/G-1 phase reenter the cell cycle,keep on proliferating and differentiating,and could reduce the occurrence of neural tube defects(NTDs). Methods When E7.75d,mice of the control group and the ganoderma spores group were given intragastrically onetime retinoic acid all-trans.Then the ganoderma spores solution was given intragastrically to the ganoderma spores group.At E10.5d,The embryos of the two groups were taken out and the ratio of NTDs was counted respectively Immunofluorescence histochemistry and flow cytometry were applied to examine the expression of nestin,and DNA quantity staining and RT-PCR to detect the mRNA transcriptions of Cdk2 and Cdk4. Results The radio of NTDs in the ganoderma spores group was lower than that in the control group remarkably,but the level of nestin was higher.With the neural tube cell cycles compared the cell radio of G-0/G-1 phase in the control group was higher than that in the ganoderma spores group,while the ratio in the S phase in the control group,it was lower than that of the normal embryos in the ganoderma spores group.The neural epithelial cell of embryonic neural tube in the ganoderma spores group could transcript Cdk4 mRNA normally,with a low transcription rate in the control group.Conclusion Ganoderma spores can reduce the occurrence of embryonic NTDs induced by retinoic acid in pregnant mice.

Objective To observe effects of soaking therapy with traditional Chinese medicine on athlete's foot. Methods346 cases of the treatment group (175 cases of erosive type and 171 cases of bullous type) were treated with soaking therapy by traditional Chinese medicine and 335 cases of the control group (170 cases of erosive type and 165 cases of bullous type) were treated with 3% Clotrimazolum ointment. Effects of two groups were compared.Results Effect of the treatment group was obviously more superior to that of the control group (P<0.0001). ConclusionsIt shows easy and effective that patients with athlete's foot were treated by soaking therapy with traditional Chinese medicine.

BACKGROUND:Different structures of matrix models, such as grating, holes and pil ars make different effects on the differentiation of neural stem cel s. OBJECTIVE:To explore the effects of the diameter and spacing, known as physical signals of micro pil ars on neural stem cel differentiation. METHODS:Micro pil ars with different diameters and spacing, both of which had four dimensions of 2.5, 5, 10 and 20μm, were fabricated on silicon substrates by photolithographic method. Purified primary neural stem cel s were incubated on the each micro pil ar for 7 days in vitro. Then the differentiation of neural stem cel s into neuron-like cel s was observed using immunofluorescence staining and quantitative real-time PCR. RESULTS AND CONCLUSION:When the diameters of the micro pil ars were constant and the spacing of micro pil ars varied in the range of 2.5-10μm, the differentiation rate of neural stem cel s increased with the spacing increase. When the spacing was invariable and the diameters changed in the range of 2.5-20μm, the differentiation rate of neural stem cel s declined with the diameter increase. Especial y, the micro pil ars with 2.5μm diameter and 10μm spacing significantly promoted the differentiation of neural stem cel s into neuron-like cel s. These results show that specific micro pil ars with smal diameters and large spacing facilitate the differentiation of neural stem cel s, thus providing guidance for developing tissue-engineered scaffolds.

Objective To investigate the feasibility and techniques of laparoscopic biliary re-operations. Methods Laparoscopic surgery was performed in 13 patients with bile duct stones who already had undergone biliary tract operations. Results Laparoscopic choledochotomy was successfully completed in 12 cases, while a conversion to open surgery was required in 1 case. The success rate of laparoscopic surgery was 92.3% (12/13). The operation time was (101～300) min, with a mean of 155 min. No intra- or post- operative complications occurred. Conclusions Laparoscopic biliary re-operations are feasible and experiences are needed to ensure the success of surgery.

Objective To explore the feasibility and curative effect of treating tubal pregnancy through the fallopian tube with interventional catheterization decrease the difficulty of the procedure and shorten the consuming time. Methods Applying the method of interventional catheterization of fallopian tube and injecting 0.5mg atropine at the cervix beforehand, then 70mg MTX was administered into the fallopian tube. Results 113 patients were successfully recovered with health except one without any adversary complication. Conclusions The interventional fallopian tube catheterization for treating ectopic pregnancy is a simple, safe, minitraumatic, quick and effective method.
