Objective:To compare the differences of short and long-term outcomes between laparoscopic surgery and open surgery treatment of intrahepatic cholangiocarcinoma patients.Methods:A retrospective cohort study was conducted to collect the clinical data of 118 patients with intrahepatic cholangiocarcinoma who underwent surgery in Qilu Hospital of Shandong University from January 2015 to June 2020. They were divided into laparoscopy group and open group according to the operation methods. The perioperative data, such as intraoperative surgical conditions, hospital costs, postoperative complications, postoperative blood biochemical tests, and the follow-up data of the two groups were compared.Results:In the laparoscopic group, there were 40 patients, 18 males and 22 females, aged (61.5±9.1) years. There were 78 patients in the open group, 48 males and 30 females, aged (61.2±8.3) years. The tumor size of the laparoscopic group was (4.4±1.8) cm, which was smaller than that of the open group (6.0±3.3) cm, and the differences were statistically significant ( P<0.05). In the laparoscopic group, 4 cases (10%) were converted to open surgery. The intraoperative blood loss, intraoperative blood transfusion proportion, 3 or more liver segments resection proportion and hospital costs of laparoscopic group were lower than those of open group [200.0(100.0, 261.8) ml vs. 300.0(100.0, 400.0) ml, 5.0%(2/40) vs. 26.9%(21/78), 37.5%(15/40) vs. 66.7%(52/78), (6.2±2.0) wan yuan vs. (7.2±2.3) wan yuan], the differences were statistically significant (all P<0.05). There were no significant differences in the incidence of postoperative complications between the two groups ( P>0.05). On the first post-operative day, ALT serum level and the third post-operative day TBil serum level in the laparoscopic group were lower than those in the open group [188.5(130.5, 274.0) U/L vs. 320.0(144.0, 427.0) U/L, 26.4(18.3, 26.4) μmol/L vs. 31.6(18.8, 37.5) μmol/l], the differences were statistically significant ( P<0.05). There were no significant differences in 1-year and 2-year overall survival rate and disease-free survival rate between the two groups ( P>0.05). Conclusion:Compared with open surgery, laparoscopic surgery in the treatment of intrahepatic cholangiocarcinoma has better short-term outcomes, and can achieve similar results in medium- or long-term outcomes.

Objective To investigate the effect of medial unicompartmental knee arthroplasty (UKA) surgery on knee biomechanics during stair ascent. Methods Nine osteoarthritis patients who received fixed-bearing medial UKA participated in this study. All patients completed pre-surgical (3 weeks before UKA surgery) and post-surgical [(7±2) months after UKA surgery] test. Their synchronized biplane radiographs during stair ascent were collected. Motion of the femur, tibia, and implants were tracked using an automated volumetric model-based tracking process that matched subject-specific 3D models of the bones and prostheses to the biplane radiographs with sub-millimeter accuracy. Anatomic coordinate systems were created within the femur and tibia and used to calculate tibiofemoral kinematics. Additional outcome measures included the center of contact in the medial and lateral compartments, and the lateral compartment dynamic joint space. Results The UKA knee was in 4.8° varus compared with the pre-surgical contralateral knee. The post-surgical UKA knee was in 3.1°valgus compared with the pre-surgical knee. The post-surgical UKA knee was 4.4° externally rotated compared with the pre-surgical contralateral knee. However, the medial tibia contact center of the UKA knee moved posteriorly 2.5 mm compared with that of the contralateral knee (P0.05). Conclusions UKA can effectively improve varus of the knee joint and restore biomechanical characteristics of UKA knee rotation, without affecting lateral compartment joint space. However, changes are found in contact center of the medial tibia compartment of the UKA knee after surgery.

Résumé
This study aims to develop the quality standards of Fructus Corni piece standard decoction. Morroniside and loganin were considered as index components. The content determination method of morroniside and loganin were developed. The fingerprint analysis method was also established. The standard decoctions of 15 batches of Fructus Corni pieces from Henan, Zhejiang, and Shaanxi were analyzed. The similarity values of fingerprint were all above 0.99. The transfer rates of morroniside were all higher than 100%. The quality evaluation indices of standard decoction were discussed. The transfer rate of an index component was not easy to be measured accurately and its concept was not rigorous. Therefore, index component yield was suggested as an evaluation index of standard decoction. Two methods for setting quality standards of standard decoctions, which were the ■ method and the ■ method, were compared. It was found that the standard range of ■ method was wider and more suitable for smaller sample size of standard decoction. The quality standards of Fructus Corni standard decoction were as follows, dry matter extraction ratio 37.48%-69.60%; morroniside yield 8.719-16.19 mg·g~(-1) piece; loganin yield 4.342-8.064 mg·g~(-1) piece.

This study aimed to establish characteristic chromatogram and content determination method for Chan Taoren formula granules,evaluate the production processes of Chan Taoren formula granules based on the correlation of characteristic chromatogram and the transfer rate of D-amygdalin,and clarify the key control points. The optimized analytical method was carried out on a Waters CORTECS C18 column(4. 6 mm×150 mm,2. 7 μm) with acetonitrile-0. 1% phosphoric acid aqueous solution as the mobile phase at a flow rate of 0. 6 m L·min-1. The detection wavelength was 207 nm,and the column temperature was 20 ℃ . As compared with the standard decoction of Chan Taoren,there were five characteristic peaks in the decoction pieces,extracts,concentrates,spray-dried powders and formula granules,basically consistent in relative retention time and peak pattern; in addition,the transfer rate of D-amygdalin from Chan Taoren pieces to the formula granules was within the transfer rate range of standard decoction. The average transfer rate of D-amygdalin was 56.65%,72.85%,94.58% and 99.29% respectively in the extraction,concentration,spray drying and granulation processes. Therefore,the factors affecting D-amygdalin in the extraction process were further studied. The results showed that D-amygdalin was easily converted to L-amygdalin in the water extraction process,leading to a low transfer rate of D-amygdalin in this process.D-amygdalin was unstable under alkaline conditions and prone to isomerization. Both liquid to solid ratio and extraction time had significant effects on the extraction rate of D-amygdalin. In this study,the key links in the production process of Chan Taoren formula granules was clarified based on the characteristic chromatogram and the quantity transmission of D-amygdalin,which provided a theoretical basis for production and quality control.

<p><b>Objective</b>A comprehensive review of the network regulation of exosomes and microRNAs (miRNAs) in neurodegenerative diseases was done, centering on the mechanism of the formation of exosomes and miRNAs and the sorting mechanism of exosomal miRNAs, with the aim to provide a theoretical basis in the search of biomarkers and the treatment of neurodegenerative diseases.</p><p><b>Data Sources</b>The comprehensive search used online literature databases including NCBI PubMed, Web of Science, Google Scholar, and Baidu Scholar.</p><p><b>Study Selection</b>The study selection was based on the following keywords: exosomes, miRNAs, central nervous system (CNS), and neurodegenerative diseases. The time limit for literature retrieval was from the year 2000 to 2018, with language restriction in English. Relevant articles were carefully reviewed, with no exclusions applied to study design and publication type.</p><p><b>Results</b>Exosomes are the smallest nanoscale membranous microvesicles secreted by cells and contain important miRNAs, among other rich contents. In the CNS, exosomes can transport amyloid β-protein, α-synuclein, Huntington-associated protein 1, and superoxide dismutase I to other cells. These events relieve the abnormal accumulation of proteins and aggravating neurological diseases. In some neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, miRNAs are pathologically altered as an inexorable course, suggesting that miRNAs may contribute neurodegeneration. Exosomes and miRNAs form a network to regulate the homeostasis of the CNS, both synergistically and individually.</p><p><b>Conclusion</b>The network of exosomes and miRNAs that regulates CNS homeostasis is a promising biomarker for the diagnosis and treatment of neurodegenerative diseases.</p>

OBJECTIVE@#To investigate the effects of preoperative portal venous injection of donor spleen cells (PVIDSC) and intraperitoneal injection of rapamycin in the acute rejection of cardiac allograft in mice and the underlying mechanisms.@*METHODS@#Homogenous female B6 mice and BALB/c mice were used as recipients and donors of heart transplantation. These mice were randomly divided into different groups and received PVIDSC alone, rapamycin alone, or PVIDSC and rapamycin combined therapy. In addition, the underlying mechanism was studied by measuring a number of cytokines.@*RESULTS@#Preoperative combination of PVIDSC and intraperitoneal injection of rapamycin significantly prolonged the survival of heterotopic cardiac allograft in mice, but had no effects on the survival time of cardiac allografts in mice pre-sensitized by skin grafting. Preoperative combination of PVIDSC and intraperitoneal injection of rapamycin increased the expression of IL-10 and Foxp3 and reduced the expression of INF-. Short-term preoperative administration of rapamycin promotes the expression of CD4CD25Foxp3 regulator T cells. However, preoperative using alone of rapamycin, or combination of PVIDSC and rapamycin had no effects on the inhibition of proliferation of memory T cells.@*CONCLUSIONS@#Preoperative application of combination of PVIDSC and rapamycin significantly prolonged the survival time of cardiac allografts in mice but not in mice pre-sensitized by skin grafting. This may be explained by the fact that combination of PVIDSC and rapamycin inhibited the cellular immune response and induced the expression of IL-10 from Tr1 cells and CD4CD25FoxP3 regulatory T cells.

Methods 427 clinicians from various departments in tertiary hospitals selected by cluster sampling method were investigate by self-rating anxiety scale ( SAS) .Statistical software SPSS 17.0 was used to analyze data for multivariate logistic regression analysis of its relevant influencing factors.Results 38.2%of the clini-cians had anxiety symptoms (55.0%was mild anxiety,26.1%was moderate anxiety,18.9%was severe anxi-ety) .Factors like education (χ2=7.3, P=0.03) ,job title (χ2=53.24, P<0.01) ,divisions (χ2=46.46, P<0.01) ,work experience (χ2=9.78, P=0.04) ,work overtime (χ2=4.29, P=0.03) ,worry of medical mal-practice (χ2=9.54, P<0.01),doctor-patient relationship tension (χ2=7.50, P<0.01),fear for personal safety (χ2=10.27, P<0.01) ,job promotion competition (χ2=11.40, P<0.01) ,labor and payment situation (χ2=6.36, P=0.01) ,colleagues'understanding and support (χ2=15.77, P=0.01) ,work environment (χ2=21.85, P<0.01) and leaders'attention (χ2=7.17, P=0.01) had significant differences between anxiety and non-anxiety clinicians.Multivariate logistic regression analysis revealed that factors like divisions ( com-pared with internal medicine,OB&GYNβ=0.98,surgeryβ=0.95,pediatricsβ=0.86,emergencyβ=0.69) , work overtime (β=0.18),fear for personal safety (β=0.86),fear of medical malpractice (β=0.79) and doctor-patient relationship tension (β=0.28) had a negative impact on anxiety,while factors like education ( compared with bachelors,mastersβ=-1.38,doctorsβ=-1.65) ,job title ( compared with primary,intermedi-ateβ=-0.33,highβ=-0.45,advancedβ=-0.59) ,work experience (β=-0.18 ) and work environment (β=-0.32) were protective factors.Conclusion There is a certain degree of anxiety among clinicians in tertiary hospitals,resulting in a heavy psychological burden on them.Active measures should be taken to improve the clinicians'psychological health.
