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.

Objective To detect the expression of orphan nuclear receptor RORC gene and the level of serum interleukin-17 in acute lung injury (ALI) rats, and to explore the effects and possible regulation mechanisms of helper T lymphocyte 17 (Th17) in the ALI.Methods Twenty four SD male rats were randomly assigned to three groups, control group, model group, and pyrrolidine dithiocarbamates (PDTC) prevention group.The rats in model group and PDTC prevention group were intravenously injected LPS (6 mg/kg) for inducing ALI.The PDTC prevention group had been intraperitoneally injected PDTC (120 mg/kg) thirty minutes before LPS injection.All rats were killed twelve hours after LPS injecttion.The lung wet/dry weight ratio was measured.Lung pathologic tissue scored after hematoxylin-eosin (HE) stain.The expression of alveolar macrophages (AM) nuclear factor-KBP65 (NF-κBP65) was detected by immunohistochemistry.The level of serum IL-17 was detected by ELISA method.The expression of AM orphan nuclear receptor RORC gene was determined by SYBR Green Ⅰ real-time polymerase chain reaction.Results Compared with control group.the lung wet/dry weight ratio.lung pathologic tissue score, the expression of AM NF-κBP65.the level of serum IL-17 and the expression of AM orphan nuclear receptor RORC gene were significantly increased (P < 0.05).However, compared with model group, these changes were prevented in PDTC prevention group.Conclusions Th17 might participate in the pathological process of ALI.Activation of NF-кB might influence RORC gene expression, induce Th17 differentiation, and elevate the level of serum IL-17.

This paper analyzed the cultivation of postgraduates of anesthesiology and the academic achievements in anesthesiology department from 2003 to 2010 in our hospital and explored the experiences in postgraduate cultivation.Cultivation of postgraduates of anesthesiology should focus on multidisciplinary integration,cross-discipline communication,extension of scientific thinking,enhancement of clinical skills so as to create the opportunity for clinical and research work.

ObjectivesTo explore the clinical manifestations and treatment ofMycoplasma pneumoniae pneumonia (MPP) combined with venous thrombosis.MethodsThe clinical manifestations and treatment of MPP combined with venous thrombosis were retrospectively analyzed.ResultsTwo male patients were 5 years 2 months and 3 years 6 months old respec-tively. After treatment with erythromycin, corticosteroids, immunoglobulin, bronchoalveolar lavage and thrombolytic, both cases were cured. Conclusions It is necessary to pay attention to the occurrence of thrombosis in MPP. Early diagnosis and treatment of thrombosis is very important for the prognosis. The prevention of thrombosis needs to be further studied.

Residency training is the mainstream model of doctor training around the world. Radiol-ogy teaching is an important part of the resident practice training. The purpose is improving and upgrading the quality of the residency training by establishing rigorous management system, intensifying the teachers disposition, setting tutorial system and reforming the examination and supervisor system, the residents.

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.
