Objective:To investigate the clinical efficacy of arthroscopy combined with sodium hyaluronate and platelet-rich plasma in the treatment of Stoller grade III meniscus injury.Methods:Sixty patients with Stoller grade III meniscus injury who received treatment in The Second People's Hospital of Liaocheng from October 2019 to October 2020 were included in this study. They were randomly divided into an observation group and a control group ( n = 30 per group). Patients in the observation group were treated with arthroscopy combined with sodium hyaluronate and platelet-rich plasma, while patients in the control group were treated with arthroscopy combined with sodium hyaluronate. Before and 1, 3, and 6 months after surgery, the Visual Analogue Scale (VAS) score, Lysholm score, and The Western Ontario and McMaster Universities Arthritis Index (WOMAC) score of the knee joint were compared between the two groups. Results:There were no serious complications in each group. Compared with pre-treatment, the VAS and Lysholm scores of the knee joint in both groups significantly decreased at 1, 3, and 6 months after surgery, while the WOMAC score showed a significant increase ( F = 514.96, 673.19, 96.31, 124.16, 230.99, 531.84, all P < 0.001). After 3 and 6 months of treatment, the VAS score in the observation group was (1.1 ± 0.5) points and (0.8 ± 0.4) points, respectively, which were significantly lower than (2.5 ± 0.7) points and (1.3 ± 0.5) points in the control group ( t = 8.91, 4.28, both P < 0.001). After 3 and 6 months of treatment, the Lysholm score of the knee joint in the observation group was (86.2 ± 9.1) points and (93.8 ± 13.2) points, respectively, which were significantly higher than (79.8 ± 11.3) points and (87.5 ± 9.2) points in the control group ( t = 2.42, 2.14, both P < 0.05). After 3 and 6 months of treatment, the WOMAC score in the observation group was (17.5 ± 3.6) points and (16.5 ± 3.2) points, respectively, which were significantly lower than (25.4 ± 5.2) points and (24.8 ± 6.4) points in the control group ( t = 6.84, 6.35, both P < 0.001). Conclusion:Arthroscopy combined with sodium hyaluronate and platelet-rich plasma is more effective in treating Stoller III grade meniscus injury than arthroscopy combined with sodium hyaluronate. The former therapy can be promoted in the clinic.

Rapid growth of high technology nowadays presents subversive characteristics, which may pose potential threats and challenges to the survival of human beings. However, the existing science and technology ethics can hardly cope with such a situation. Therefore, it is necessary to develop and establish an ethics system with strict logic and complete system, and of Chinese characteristics as well. In view of the practice in medical and life science field, this paper put forward suggestions in this regard.

Objective: To present the evolutionary path of Chinese Medical Ethics, analyze the development vein of periodical, explore the journal' s research focuses, and provide reference for related personnel to understand the development of the current research status in the field through visualization technology. Methods:Using biblio-metric method,taking "China National Knowledge Infrastructure" as source of data collection, we used the visual-ization software CiteSpace to draw scientific knowledge maps and analyzed literatures published from 1990 to 2014 in Chinese Medical Ethics. Results:The annualvolume of journal articles fluctuated upwards,with peaks in 1992, 2000 and 2009, and of which the most was in 2009, with 393 articles. "Medical Ethics" and "Doctor-patient Relationship" were hotwords in this field. The publications of domestic and foreign scholars promoted the interna-tional exchange and the development of Chinese medical ethics, and the most productive institutions were often col-leges or universities. Conclusion:Chinese Medical Ethics has effectively promoted the development of bioethics in China, more and more scholars are involved in the relative research of medical ethics, and the old, middle and young scientists and research teams inherit, cooperate and develop with each other. The cross-regional, inter-a-gency and interdisciplinary collaboration remains very limited, whichwill become the important factorinfluencingthe development of the field of Chinese medical ethics in the future.

This paper, on top of its introduction of the concept of medical ethics counseling, analyzed the necessity of establishing a medical ethics consultation system in China.By reviewing the development of the medical ethics counseling system in other countries, the authors, in view of China′s medical practice, put forward specific recommendations on establishing a medical ethics counseling system in China.Issues on the construction of organ donation ethics counseling system in China were also discussed in focus.

Objective:To investigate the reasons of the tension of doctor-patient relationship and the medical violence from the perspective of the doctors, in order to provide a reference for finding a viable solution. Methods:Questionnaires survey were conducted about doctors' working conditions in 45 hospitals of 9 provinces. Results:On-ly 3. 6% medical staff had a harmonious doctor-patient relationship, the causes for the tense doctor-patient rela-tionship were poor communication with patients (75%), medical limitations (46. 2%);From the patients perspec-tive, the patients 'unpleasant caused by overtreatment due to complex illness accounted for 54. 2%;Institutional health-related reasons accounted for 82 . 6%. Conclusions:In the past five years after the new health care re-form, the tense doctor-patient relationship has not been released. So, should focus on training to enhance the com-munication skills of medical personnel and medical humanities education while the implementation of the national health care reform, in order to reduce iatrogenic conflicts.

This paper discussed the main point specifically from the three aspects which are the certainty and uncertainty of technological function , the predictability and unpredictability of technological efficiency , and“should do”or“not should do”of technological application .It presented an ethics argument of medical technology clinical admittance restriction and defends the standpoint -what we can do does not mean what we should do , aiming to provide moral theoretical support of ethical review of medical technology application .

Objective To investigate epidemic characteristics of HCV and the distribution of naturally occurring resistance mutations of HCVNS5B in Hubei province,and provide the basis for individualized antiviral treatment for HCV infected pa-tients.Methods Collected HCV blood samples of 253 patients from March 2011 to May 2014 in Renming Hospital of Wu-han University,and determined the subtypes of HCVNS5B by first generation of sequencing technology,then compared the result with the nucleotide sequence of HCVNS5B online,located drug resistance loci and record.Results There were 4 gen-otypes and 6 different genetic subtypes in these 253 cases,namely 1a subtype 3,1b subtype 192,2a subtype 38,3a subtype 3, 3b subtypes 11 and 6a subtypes 6.Found 27 gene locus of resistance from 234 different places.The main drug resistance lo-ciare L159F (475-477)26.42%,followed by C316Y (946-948)16.98%,V321I (961-963)15.09% and S282T (844-846) 12.58%.Conclusion The epidemic characteristics of HCV in Hubei province were consistent with those of current in Chi-na;subtype 1b was the main types,followed by 2a subtype.The number of drug-resistant of HCVNS5B was more and com-plex,and presented some popular distributions.It was complex in mutations of 2a subtype,including 13 mutations of natural resistance.There were fewer mutations in subtype 1b,including sites of L159F and C316N.These results may provide the basis for antiviral therapy for HCV patients in this region.

We should explicitly put forward the concept of health quotient(HQ).That is to say,HQ reflection of the health consciousness,health knowledge and health level of individual and residents in a region;also the degree of HQ can be reflection through peoples' having health consciousness,health knowledge,health ability with those should have.The author thinks HQ is very important for people's health;furthermore,some suggestions how to raise HQ was proposed.

With the development of knowledge economy, society has more and more high demand for professional quality. Medical students are the reserve talents for the health care industry of our country, so it plays an important role in keeping people's health by improving the professional quality of medical students. Therefore, we should put more emphasis on the education of professional consciousness, professional moral, professional spirit, professional ideal and professional rights and interests, making students form the healthy medical professional personality, to establish the foundation for the sustainable development of the health care industry.
