Yttrium-90 selective internal radiation therapy (⁹⁰Y-SIRT) is a treatment technique that delivers radioactive microspheres precisely to the arterial vascular bed of neoplasms, utilizing beta radiation to administer a high local dose of radiation to the neoplasm tissues. This technology has demonstrated significant efficacy in patients with unresectable pirmary liver cancers and liver metastases. This article systematically reviews the development history and clinical application status of ⁹⁰Y-SIRT in the treatment of liver cancer, and looks forward to future development directions.

This article inherited and summarized the application of Professor Tang Xudong's"New Eight Principles in the Syndrome Differentiation and Treatment of Spleen and Stomach Diseases"(abbreviated as"New Eight Principles")in the field of chronic liver disease.It believed that chronic liver disease should be distinguished from the four aspects of"zangfu organs-qi and blood-deficiency and excess-cold and heat".The differentiation of zangfu organs is mainly focused on regulating the liver and spleen,while also taking into account other organs;the differentiation of qi and blood emphasizes the knowing of its excess and deficiency,and the administrative levels of the disease;the differentiation of deficiency and excess is based on the principle of qi-deficency and blood-stasis,and strengthens body resistance and eliminating evil;for the differentiation of cold and heat,liver-gallbladder dampness-heat syndrome is the most common,but do not forget the liver cold syndrome.On this basis,Tongjiang theory is used as the treatment legislation,making it easier to be mastered,and guiding the prescription and medication of chronic liver disease throughout the entire stage,which can achieve good efficacy.

Objective    To investigate the effect of in vitro fenestration on reconstruction of left subclavian artery in endovascular treatment of aortic dissection. Methods    A total of 89 patients with aortic dissection involving left subclavian artery were treated by endovascular treatment in the Second Affiliated Hospital of Fujian Medical University from February 2017 to January 2020. There were 44 patients in the test group, including 36 males and 8 females, with an average age of 58.02±13.58 years. There were 45 patients in the control group, including 35 males and 10 females, with an average age of 54.10±12.32 years. The left subclavian artery was reconstructed by in vitro fenestration in the test group and by chimney technique in the control group. The clinical data were compared between the two groups. Results    The operation time of the test group was longer than that of the control group (126.16±7.53 min vs. 96.49±6.52 min, P<0.01). The median follow-up time was 31 (13-48) months. The incidence of endoleak in the test group (4.7%) was lower than that in the control group (18.6%, P=0.04) during the follow-up. There was no statistical difference in the incidence of stroke, myocardial infarction, false lumen thrombosis, retrograde aortic dissection or left subclavian artery occlusion between the two groups (P>0.05). Conclusion     In vitro fenestration for reconstructing left subclavian artery in thoracic endovascular aortic repair of aortic dissection is safe and feasible, which is worthy of further clinical promotion.

The chemical complexity of traditional Chinese medicines (TCMs) makes the active and functional annotation of natural compounds challenging. Herein, we developed the TCMs-Compounds Functional Annotation platform (TCMs-CFA) for large-scale predicting active compounds with potential mechanisms from TCM complex system, without isolating and activity testing every single compound one by one. The platform was established based on the integration of TCMs knowledge base, chemome profiling, and high-content imaging. It mainly included: (1) selection of herbal drugs of target based on TCMs knowledge base; (2) chemome profiling of TCMs extract library by LC‒MS; (3) cytological profiling of TCMs extract library by high-content cell-based imaging; (4) active compounds discovery by combining each mass signal and multi-parametric cell phenotypes; (5) construction of functional annotation map for predicting the potential mechanisms of lead compounds. In this stud TCMs with myocardial protection were applied as a case study, and validated for the feasibility and utility of the platform. Seven frequently used herbal drugs (Ginseng, etc.) were screened from 100,000 TCMs formulas for myocardial protection and subsequently prepared as a library of 700 extracts. By using TCMs-CFA platform, 81 lead compounds, including 10 novel bioactive ones, were quickly identified by correlating 8089 mass signals with 170,100 cytological parameters from an extract library. The TCMs-CFA platform described a new evidence-led tool for the rapid discovery process by data mining strategies, which is valuable for novel lead compounds from TCMs. All computations are done through Python and are publicly available on GitHub.

Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary. RESULTS: A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001). CONCLUSIONS The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.

Objective To evaluate changes of the urodynamics of extraperitoneal Studer orthotropic ileal neobladder after radical cystectomy.Methods Between July 2013 and October 2017,Retrospective analysis was performed on 58 bladder cancer patients.58 patients who underwent retrograde extraperitoneal approach of radical cystectomy and Studer orthotopic ileal neobladder.The patients were comprised of 56 male and 2 female patients with average age of 62 years.There were 9 cases of T1,26 cases of T2,20 cases of T3,and 3 cases of T4.All operations were completed by open suprapubic extraperitoneal approach,then entered the abdominal cavity.An ileal segment 50-55 cm long was isolated which was 25 cm proximal to the ileocecum.The 35-40 cm ileal segment was detubularized along its antimesenteric border.The anterior wall was folded forward with U-shaped and the edges were sutured to formed a neobladder.The proximal 15cm was reserved for the double isoperistaltic afferent limb.The lowest part of the neobladder was anastomosed with urethral stump,the peritoneum was closed at the mesentery,and the neobladder was completely placed extraperitoneal.Upper urinary tract function was examined by renal function test,enhanced CT,IVU or cystography.Uroflowmetry,urodynamic evaluation,diurnal and nocturnal continence were performed at 3,6,12,24 months following the surgery.Results After removed of the catheter,all patients were able to urinate through the urethra.The 3,6,12,24 month follow-up data of urodynamic were compared.The maximum neobladder capacity was[(378 ±66) vs.(381 ± 102)vs.(438 ± 75)vs.(472 ±96)] ml,the maximum flow rate [(10.2 ± 2.8) vs.(14.9 ± 4.3) vs.(16.4 ± 3.6) vs.(17.6 ± 2.1)] ml/s,maximum bladder pressure during filling was [(23.0 ± 4.6) vs.(21.7 ± 7.1) vs.(20.6 ± 6.4) vs.(18.8 ±6.3)] cmH2 O,the PVR was[(68.0 ± 33.2) vs.(36.2 ± 10.1) vs.(30.6 ± 11.9) vs.(14.0 t 9.6)] ml.There were significant differences between the 6-month and 12-month.There were no significant differences in the maximum bladder pressure during flowing [(38.6 ± 7.4) vs.(49.2 ± 6.8) vs.(58.4 ± 10.5) vs.(56.8 ± 7.4)] cmH2O.53 cases were followed up 12 months after surgery.Excellent daytime and nighttime continence was 98％ (52/53)and 83 ％ (44/53)in the first year.Mild unilateral hydronephrosis occurred in 2 cases 1 month after surgery.Blood electrolytes and renal function were within the normal range.1 case presented bilateral mild hydronephrosis 12 months after surgery,without bladder and ureter regurgitation.The blood electrolyte and renal function of the other patients were in normal range with no signs of ureteral stricture and upper urinary tract hydronephrosis.Conclusions Extraperitoneal Studer orthotopic ileal neobladder reduced the interference of postoperative intraperitoneal intestinal tract on neobladder function.Postoperative patients have a smooth urination,a safe pressure during the storage period.The urination period,and the function of day and night urinary control is close to normal physiological characteristics.

Objective? To explore the effects of hydrocolloid dressing on preventing nasotracheal intubation related nasal alar pressure injury among patients with orthognathic surgery. Methods? From November 2016 to September 2017, we selected 450 patients with orthognathic surgery in Peking University School and Hospital of Stomatology by the study design of synchronous randomized controlled trial. All of the patients were divided into observation group and control group with the random number table, 225 cases in each group. Control group carried out nasotracheal intubation fixed by conventional method. Observation group received fixing by hydrocolloid dressing. We compared the incidence of nasal alar pressure injury of patients between two groups. Results? The incidence of nasal alar pressure injury of patients in observation group and control group was 4.44%(10/225) and 14.22%(32/225) respectively. The incidence of observation group was lower than that of control group with a statistical difference (χ2=12.710, P＜0.01). Conclusions? Nasotracheal intubation fixed by hydrocolloid dressing helps to protect the skin of nasal alar among patients with orthognathic surgery to reduce the incidence of nasal alar pressure injury.
