【Objective】 To investigate the effects of different anticoagulants on platelet-rich plasma(PRP) release content of growth factor and injection pain. 【Methods】 A total of 15 voluntary blood donors were selected, with each blood donor using four kinds of anticoagulant tubes with EDTA-K2 anticoagulation, EDTA-NA2 anticoagulation, citrate anticoagulation, ACD-A anticoagulation respectively as group A, B, C and D. PRP was isolated and prepared by the rich plasma method, and the contents of PDGF-AA, TGF-β, IGF-1, VEGF, and PF-4 were detected by enzyme-linked immunosorbent assay. Meanwhile, SD rats (20, 4 / group) were injected subcutaneously or intradermally with the supernatant of PRP and PG gel prepared in the 4 groups and normal saline in the control group. The pain status of SD rats during the injection was observed and recorded. The pain status of the 5 groups of experimental animals was evaluated according to the American Laboratory Animal Pain Guide. 【Results】 The platelet counts in PRP in group D was the highest [(1 294.53±277.37) × 10⁹/L], which was significantly higher than that in group A [ (789.13±377.13) ×10⁹/L] and group C [ (990.94±493.12) ×10⁹/L] (P<0.05). The OD value of PDGF-AA in group A, B, C, and D were 1.51± 0.18, 1.69±0.21, 0.66±0.19and 1.72±0.13, respectively, with statistically significant difference between groups (P<0.05 ) and group D better than the other three groups. The OD value of PF-4 was 1.18±0.24, 1.61±0.14, 0.65±0.26 and 1.72±0.10 respectively, with statistically significant difference between groups (P<0.05) and group D better than other three groups. The OD value of IGF-1 was 1.02±0.08, 0.98±0.11, 1.06±0.11 and 1.32±0.65 respectively, with no significant difference between groups (P>0.05). The OD value of VEGF was 0.13±0.04, 0.21±0.14, 0.08±0.02 and 0.13±0.04 respectively, with statistically significant difference between group B and C (P<0.05). The OD value of TGF-β was 0.14±0.01, 0.15±0.01, 0.28±0.17 and 1.10±0.37 respectively, with statistically significant difference between groups (P<0.05) and group D better than other three groups. Comparison of injection pain: when the supernatant of PRP and PG gel was injected, there were significant differences between group A, B, C and D, and the control group (P<0.05) . The median pain scores of PRP injection of group A, B, C, and D were 6 (1.5), 5 (0.75), 4.5 (2.5), and 3(3) respectively, with group D lower than other three groups, and no statistically significant difference was noticed (P>0.05) . The median pain scores of the PG supernatant injection of group A, B, C, and D were 4 (2.25), 3 (2.75), 4 (3), 1 (1.5), and the difference was not statistically significant (P>0.05). There was no significant difference between the PRP injection group and the PG supernatant group (P> 0.05). 【Conclusion】 PRP prepared by two-step centrifugation with ACD-A anticoagulant can obtain the higher platelet counts and the maximum release of PDGF-AA, PF-4, IGF-1, and TGF-β. In terms of pain, ACD-A anticoagulant injection has the lowest pain with the animals.

【Objective】 To develop a spray-on membrane dressing for wound repair containing platelet rich plasma (PRP) sodium alginate (SA)/agarose(AG)/carboxymethyl chitosan (CMCS). 【Methods】 SA/AG/ CMCS were mixed in different proportions to prepare biodegradable quick setting spray (BQSS) by blending film method, and the film-forming time, moisture retention and compression resistance of the prepared BQSS were tested. Then PRP and BQSS were mixed in the proportion of 3∶7, 4∶6, 5∶5, 6∶4 and 7∶3 to prepare PRP-BQSS spray film dressings. The film-forming time, moisture retention, compressive strength, porosity and slow-release effect of growth factors of PRP-BQSS spray film dressings were studied. 【Results】 In the preparation of BQSS compound spray film solution, when SA, AG, CMCS and sterile distilled water were 0.6∶0.6∶0.6∶98.2g, the film-forming time (7.73±0.31) s, moisture retention (75. 54±3.03) % and compression resistance (791.00±68.02) g of the spray-film dressing were the best. The basic properties of PRP-BQSS spray-on film dressings and the release of growth factors show that PRP-BQSS spray-on film dressings can exist in different forms, and with the decrease of PRP concentration percentage, its film-forming time, moisturizing performance and compressive strength showed an upward trend. When the PRP content is 30%, the porosity of the dressing is the highest, about(84.34±0.90)%. The release of platelet-derived growth factor-AA(PDGF-AA), platelet factor-4(PF-4) and transforming growth factor beta (TGF-β) was in a slow upward trend, and the release of the three growth factors was higher than that of PRP group in 48 hours. 【Conclusion】 The preparation method of PRP-BQSS spray film dressing designed in this study is simple and mild, and can form a film quickly, with good biological properties and better growth factor inhibition and sustained-release effect.

In recent years, the artificial intelligence machine learning and deep learning technology have made leap progress. Using clinical decision support system for auxiliary diagnosis and treatment is the inevitable developing trend of wisdom medical. Clinicians tend to ignore the interpretability of models while pursuing its high accuracy, which leads to the lack of trust of users and hamper the application of clinical decision support system. From the perspective of explainable artificial intelligence, the authors make some preliminary exploration on the construction of clinical decision support system in the field of liver disease. While pursuing high accuracy of the model, the data governance techniques, intrinsic interpretability models, post-hoc visualization of complex models, design of human-computer interactions, providing knowledge map based on clinical guidelines and data sources are used to endow the system with interpretability.

【Objective】 To analyze the influencing factors of clinical efficacy of autologous platelet-rich plasma in the treatment of androgenetic alopecia. 【Methods】 From January, 2019 to December, 2021, 151 outpatients with androgenetic alopecia were treated in our hospital. All patients were treated with autologous PRP injection once a month and planned to received injection for 4-6 occasions. According to the hair growth before and after treatment, the treatment results were evaluated. The influencing factors in the treatment results were grouped and analyzed, including the treatment numbers (divided into 1-6 occasions), the grade of alopecia(three grades: mild, moderate and severe alopecia) and the Plt concentration in PRP[five grades(×10⁹/L): extremely low concentration (<800), low concentration (801-1 000) and medium concentration (1 001-1 200), high concentration(1 201-1 500)and extremely high concentration(>1 501)]. 【Results】 The correlation coefficient between the number of treatments and the effective rate was pearson=0.986, P<0.001, showing a positive correlation. There was a statistical difference in the total number of treatments between groups (P<0.01). As to the severity of alopecia: The effective rates of mild and moderate alopecia patients (66.67%, 56.95%) were higher than those of severe alopecia patients (35%). The difference between groups was statistically significant (P<0.01). As to the concentration of Plt in PRP: The concentration of Plt directly affected the therapeutic effect. When the Plt count was (1 200-1 500)×10⁹/L, the effect was optimal, reaching 68.12%, which was significantly higher than the other four groups(P<0.01). The treatment numbers, alopecia grade and Plt concentration in PRP were all related to the effectiveness of treatment (P<0.05). When the OR value of treatment numbers and Plt concentration was >1, the effective rate increased by 2.619 times and 2.033 times, respectively, as treatment numbers and Plt concentration increased. When the OR value of the grade of alopecia was 0.338 (0<0.338<1), the effective rate decreased with the increase of alopecia severity; For each grade increased, the effective rate would be compromised by 0.338. 【Conclusion】 When PRP is applied to treat AGA patients, the clinical therapeutic effect will be better in patients who received more treatments, PRP with higher Plt count, and be in the early degree of hair loss. Whether the higher the concentration of Plt in PRP, the better the therapeutic effect will be, remains to be further verified.

To explore the mode of"one-day outpatient"based continuous management and examine its feasibility and preliminary effects for improving menopausal syndrome and mood among menopausal women.Clinical intervention study was conducted in Obstetrics and Gynecology Center of the Third Affiliated Hospital of Chongqing Medical University from May 2020 to May 2021.The continuous management mode of "one-day outpatient service" for menopause was constructed in terms of multidisciplinary resources, including offline "one-day outpatient" health education, online 7-week group continuous intervention on "healthy lifestyle" and offline half-day focus group interview. Pre-and post-scores of the modified Kupperman scale and the positive/negative emotional scale (PANAS) were measured to compare the status of menopausal syndrome and emotional experience of Seventy-eight female participants (40-60 years old), meanwhile, before and after comparison of the blood lipid and body composition indexes of participants were also performed. Paired t test or Wilcoxon signed rank test were used.Results show that the pre-and post Kupperman scores were 14.65±8.51 vs 10.26±5.83 ( t=-5.59, P<0.01), and the positive emotional scores (pre- 28.53±5.85 vs post- 30.13±6.30) were improved ( t=2.59, P=0.012) and negative emotional scores [pre- 20.5(10) vs post- 17.0(7)] were decreased ( Z=-5.09, P<0.01). The triglyceride level of participants declined from (1.27±0.54) mmol/L to (1.09±0.38) mmol/L ( t=-2.45, P<0.05). In addition, the body mass index(pre- 22.52±2.34 vs post- 22.06±2.22), percentage of body fat (pre- 31.72±6.22 vs post- 30.91±6.52)and Visceral fat area(pre- 83.96±30.26 vs post- 79.66±29.71) were all improved ( t=-3.58, t=-2.57, t=-2.59, P<0.05). Therefore,the mode of"one-day outpatient"based continuous management can effectively improve menopausal syndrome and adverse mood, reduce patients′ blood lipid, improve the body composition, and maybe contribute to the prevention of long-term chronic diseases.
