BACKGROUND: The complicated localization of intramedullary nails and osteotomy more dependent on surgeons' experience limit the application of conventional total knee arthroplasty (TKA). The occurrence of three-dimensional (3D) printing technology can achieve precise localization and osteotomy in TKA.OBJECTIVE: To explore the effectiveness of 3D printing technology-aided TKA versus conventional TKA for genu varum.METHODS: Thirty-four patients with genu varum undergoing primary unilateral TKA were recruited and were then divided into two groups (n=17 per group) in accordance with the random number table. One group was treated with TKA with 3D printing guild plate (3D printing group), while the other group received the conventional TKA (conventional group).The intraoperative and postoperative blood loss, operation time, as well as the Hospital for Special Surgery score, range of motion, and lower limb mechanical alignment at 2 weeks postoperatively were compared between two groups.RESULTS AND CONCLUSION: (1) The range of motion of knee in the 3D printing group was larger than that in the conventional group, but had no significant difference at 2 weeks postoperatively (P=0.744). (2) There was no significant difference in the Hospital for Special Surgery scores between two groups at 2 weeks postoperatively (P= 0.532). (3) The postoperative lower limb mechanical alignment showed no significant difference between two groups (t=0.218, P=0.632).(4) The operation time in the 3D printing group was significantly shorter than that in the conventional group (P=0.000). (5) The blood loss in the 3D printing group was significantly less than that in the conventional group (P=0.000). (6) Our findings indicate that 3D printing technology-aided TKA exhibits similar results to the conventional TKA in the Hospital for Special Surgery scores, range of motion, and lower limb mechanical alignment, but it shortens the operation time,reduces the blood loss, and achieves precise osteotomy, which is available for the elderly with poor basic condition, and weak tolerance of surgery.

Objective:To explore the clinical effect of Bobath manipulation combined with traditional Chinese medicine fumigation and intradermal acupuncture on shoulder hand syndrome(SHS) after stroke.Methods:From April 2017 to August 2019, 80 patients with SHS after stroke admitted to the People's Hospital of Deqing County were selected, and they were divided into control group and observation group according to the random digital table method, with 40 cases in each group.The control group was treated by Bobath therapy, and the observation group was treated by Bobath therapy combined with acupuncture(intradermal acupuncture) and traditional Chinese medicine fumigation.After 8 weeks of treatment, the ROM scale, FMA scale, BI scale and VAS scores were used to evaluate the improvement in the mobility of the shoulder and wrist joints, motor function of the upper limbs, quality of life and pain, and the clinical efficacy of the two groups was compared.Results:Compared with before treatment, the ROM scale score of all dimensions of shoulder and wrist mobility, FMA scale score and BI scale score of all patients after treatment increased significantly, and the VAS score decreased significantly, the differences were statistically significant(all P<0.05). Compared with the control group after treatment, the improvement of the indicators mentioned above of the observation group were better[shoulder joint flexion ROM score: (154.83±25.63)points vs.(133.82±22.03)points; shoulder joint abduction ROM score: (152.36±25.68)points vs.(133.35±19.96 )points; shoulder joint external rotation ROM score: (75.87±14.69)points vs.(60.82±16.57 )points; wrist joint palm flexion ROM score: (73.94±14.37)points vs.(57.37±9.47)points; wrist joint back extension ROM score: (60.83±7.61)points vs.(42.27±6.37 )points; FMA scale score: (45.74±6.82)points vs.(34.19±4.07)points; BI scale score: (70.36±12.09)points vs.(58.70±12.53)points; VAS score: (1.05±0.49)points vs.(3.37±1.14)points, t=3.703, 3.715, 3.257, 5.576, 7.964, 3.037, 8.746, 3.153, all P<0.05]. The total effective rate of the observation group was significantly higher than that of the control group[97.5%(39/40) vs.62.5%(25/40), χ 2=15.313, P<0.05)]. Conclusion:The combination of Bobath therapy with traditional Chinese medicine fumigation and intradermal acupuncture can improve the pain degree, joint mobility disorder, upper limb motor function and quality of life of SHS patients, the efficacy is better than single Bobath therapy.The clinical effect is accurate, and it is worthy of further promotion and application.

In the past ten years, the research and application of microbiome has continued to increase. The microbiome has gradually become the research focus in the fields of life science, environmental science, and medicine. Meanwhile, many countries and organizations around the world are launching their own microbiome projects and conducting a multi-faceted layout, striving to gain a strategic position in this promising field. In addition, whether it is scientific research or industrial applications, there has been a climax of research and a wave of investment and financing, accordingly, products and services related to the microbiome are constantly emerging. However, due to the rapid development of microbiome sequencing and analysis related technologies and methods, the research and application from various countries have not yet unified on the standards of technology, programs, and data. Domestic industry participants also have insufficient understanding of the microbiome. New methods, technologies, and theories have not yet been fully accepted and used. In addition, some of the existing standards and guidelines are too general with poor practicality. This not only causes obstacles in the integration of scientific research data and waste of resources, but also gives related companies unfair competition opportunity. More importantly, China still lacks national standards related to the microbiome, and the national microbiome project is still in the process of preparation. In this context, the experts and practitioners of the microbiome worked together and developed the consensus of experts. It can not only guide domestic scientific research and industrial institutions to regulate the production, learning and research of the microbiome, the application can also provide reference technical basis for the relevant national functional departments, protect the scale and standardized corporate company's interests, strengthen industry self-discipline, avoid unregulated enterprises from disrupting the market, and ultimately promote the benign development of microbiome-related industries.
