ABSTRACT
Under the background of " Internet+ medical treatment" and the continuous deepening of face recognition technology research, the face recognition industry has continued to mature, and face recognition has been initially applied in medical fields such as hospital management, auxiliary medical care, and epidemic prevention and control. At the same time, face recognition technology brings problems including error risk, technical cracking risk, privacy risk, equality risk, abuse risk, and other issues in practice, which seriously threaten the personal and property rights and interests of the public. On the basis of summarizing the specific application direction of face recognition technology in hospitals, the authors sorted out the legal regulation of face recognition in China, and proposed that it should be based on technology research and development, strengthen the " gatekeeper" responsibility of medical institutions, improve legal system and recommendations for strengthening judicial leadership in order to improve the legal regulations of face recognition technology, reduce the risk of infringement by medical institutions in the application of face recognition technology, and protect the legitimate rights and interests of citizens.
ABSTRACT
With the steady progress of the rule of law for Internet in China, " Internet+medicine" is drawing greater attention and legislative demand. The enactment of E-commerce Law in early 2019 has provided rich legal connotations of " Internet+" commerce scenario, clarifying its legal subject scope and legal service scope.The authors analyzed the legal system of medical E-commerce, and the legal obligations of medical E-commerce. From the following four aspects of legitimate business conduct, consumer rights protection, platform responsibility and intellectual property protection, the authors held that the current legal regulation of medical E-commerce is plagued by major setbacks as follows.These setbacks include incomplete legislation, low legal ranking, ambiguous subject definition and legal guidance, as well as lack of behavior regulation and unclear legal obligations.In this regard, the state is recommended to advocate the enactment of the Pharmaceutical E-commerce Law, speed up the revision of a series of laws and regulations, and improve the supporting service policies as a whole, so as to strengthen the rule of law regulation of future pharmaceutical E-commerce.

ABSTRACT
Objective To determine the clinicopathologic characteristics and prognostic factors that may be used to predict the poor outcome of patients with borderline ovarian tumors. Methods All cases with borderline ovarian tumors treated in the West China Second University Hospital from January 2001 to June 2007 were analyzed retrospectively for elinicopathologic features, treatment parameters and outcome of treatment. Univariate and multivariate analyses were used to assess independent prognostic factors using the logistic regression model. Results The median age of 234 patients was 40. 1 years with a range of 14 to 80 years. There were 101 (43.2%), 94 (40.2% ) , 19 (8.1% ), 12 (5.1%) , 8 (3.4%) cases of serous, mutinous, mixed, endometrioid and clear cell tumors, respectively. Out of 234 cases, 182 (77.8%) underwent laparotomy and 45 ( 19.2% ) underwent laparoscopy. Seven women underwent laparoconversion. Fertility sparing surgery was performed on 119 cases (50.9% ) and radical surgery was performed on 115 cases (49.1% ). Totally 161 (68.8% ) patients had stage Ⅰ , 19 ( 8.1% ) had stage Ⅱ, 54 ( 23.1% ) had stage Ⅲ, and none had stage Ⅳ disease. Sixty-four women received postoperative chemotherapy. The median follow-up was 40 months with a range of 8 to 78 months. Recurrence was found in 26 cases (11.1%) during follow-up, and no tumor-related death was reported. The logistic regression model showed that surgery procedure ( OR=2.304, P=0.024), cyst rupture ( OR=2.213, P=0.038 ), stage ( OR= 4.114, P<0.01 ), microinvasion ( OR=2.291, P=0.046) and peritoneal implants ( OR=2.101, P = 0.016) were the five independent prognostic factors affecting recurrence. Conclusions Although patients with borderline ovarian tumors have an excellent prognosis, the risk of recurrence remains in some patients. Emphasis should be put on these patients with high risk factors and preventive strategies should be taken to prevent their progression.
