This paper introduces the development situation and mode of physician group in China, and analyzes its main legal risks and countermeasures.The main legal risks include: the nature of the Physician group is fuzzy and specific laws and regulations lack a clear stipulation;the legitimacy of the cooperative mode of the physician group is difficult to define and lacks legal protection for its contract effectiveness and implementation;the practice is driven by the interests and loopholes in legal norms and physicians may illegally transfer the patients;the multipoint practice policy is not perfect and brought legal risks for the development of the physician group.Therefore, the following measures are proposed to take adequate precautions: firstly, the nature of the physician group and its standards of supervision and taxes should be identified and clarified;secondly, the legitimacy standard for the physician group should be established for its cooperation mode to standardize the doctors` behavioral standards;and finally, we should make sure the multipoint practice policy and physician practice law are coherent during implementation.

The amount-based restriction of negotiation in private when resolving medical disputes is quite com-mon in much local legislation.This kind of provision is legitimate in general, because the rights and interests it pro-tects overweigh those it limits, and the measures it takes are proper.However, there are several flaws.Firstly, as a provision which impairs the rights of citizen, the level of legislation and legal effect need to be upgraded.Secondly, the set of the amount of limitation is arbitrary.Thirdly, differential treatment of public and non-public medical insti-tution in the provision cannot be justified;it actually shows confliction between different government functions.Last-ly, blindly limitation of negotiation in private has neglect something important, that is the self-government functions behind autonomous disputes settlement mechanism.Based on these flaws, several improvement suggestions are pro-vided.

Objective To explore the clinical features of primary cervical adenocarcinoma in order to improve the level of diagnosis and treatment.Methods The clinical data of 25 patients with primary cervical adenocarcinoma were retrospectively analyzed.Results The age was 18-75 (53.23 ± 11.37) years old and 20 (80％,20/25) patients was postmenopause.The gynecologic examination showed that cervical shape was irregular,cervical canals pachynsis,hardening,extension and widen.The gross type included 1 case of erosio lump type,2 cases of fungating type,17 cases of nodus and induration ulcer type,5 cases of cervical canals type.Twenty-two patients received extensive hysterectomy and 2 patients received sub-extensive excision,1 patient was forbiddened and was only received chemical therapy for the abdominal extensively adhesions with little ascites.Twenty-three patients were performed surgery and extracorporeal irradiation or high to midst dose rate after loading program radiotherapy; twelve of them were performed chemoradiation,but eleven patients couldn' t tolerable the chemical side effects and only took radiotherapy.The 5-year survival rate was 76％ (19/25).The poorest prognostic patients were the stage Ⅳ women,which died after 3 months and 9 months respectively from first visit the doctor.The mass diameter and the early FIGO stage were correlated with prognosis (P ＜0.05).But age,gross type,pathological type,treated methods had no correlation with prognosis (P ＞ 0.05).Conclusions Cervical adenocarcinoma would be predilection postmenopause female.The common signs include cervical shape irregular,cervical canals pachynsis,hardening,extension and widen.The 5-year survival rate of the patients who received operation combined modality therapy in early stage and with small mass size is higher.The prognosis would be poor relatively in late FIGO stage and mass diameter over 4 cm.So,early discovery,early diagnosis and early treatment would be the key ways to improve 5-year survival rate.

TCM hospital preparation, which is only used inside its own orgnations, is an important part of clinical medicine in TCM. In recent years, the lack of a corresponding constitution of legal safeguard seriously hampered the prosperities of TCM hospital preparations. It's a high time to settle a targeted legal safeguard constitution of TCM preparations developed by the hospital. The author takes hospital of TCM preparation as the research object, starting from the current situation and problems of development of hospital of TCM to dig out the reasons. It has great significance to ensure the status of TCM preparation developed by the hospital at first, to combine with other measures. and to put forward about the establishment of comprehensive legal safeguard mechanism for the development TCM hospital preparation.
