ABSTRACT
This paper summarized professor ZHANG Boli's experience in treating stubborn bi （痹） with the herbal pair of Ruxiang （Olibanum）- Moyao （Myrrha）. The basic pathogenesis of stubborn bi is channel and collateral stasis and obstruction. Ruxiang and Moyao are thus used in mutual reinforcement to rectify qi and diffuse bi， activate blood and relieve pain， thereby removing static and obstructed qi and blood， unblocking the obstructed channels and colla-terals， which is especially suitable for stubborn bi caused by channel and collateral obstruction. In clinical practice， the herbal pair of Ruxiang-Moyao is used together with qi-moving and blood-activating medicinals to treat chest bi by expelling stasis and diffusing stagnation， dissipating cold and unblocking vessels. To treat long-term wither and weakness in late stage of stroke， the medicinals of boosting qi and invigorating blood， unblocking channels and venting collaterals can be added to the herbal pair so as to soothe and drain vessels and collaterals， harmonize and regulate qi and blood. Simiao Yongan Decoction （四妙勇安汤） can be integrated in the treatment of vessel bi by moving qi and dissolving stasis， and for the long-term stubborn vessel bi， integrated internal and external treatment is suggested by external use of Ruxiang-Moyao to vent bi with aromatics. Moreover， it is emphasized to use the herbal pair of Ruxiang-Moyao in accordance with indications and cautions.
ABSTRACT
ObjectiveTo investigate the effect of LncRNA GAPLINC on the cell proliferation of RA-FLSs. MethodsRA-FLSs were cultured from synovial specimens. The expression of LncRNA GAPLINC in RA-FLSs and trauma-FLSs groups was detected by qRCR. GAPLINC suppression was transfected by siRNA and the inhibition efficiency was detected by qRCR. Flow cytometry was adopted to determine the change of cell growth and cell cycle distribution. 【ResμLts】 The expression of LncRNA GAPLINC was significantly higher in RA-FLSs than that of the trauma-FLSs （P<0.05）.Transfection of GAPLINC-siRNA significantly decreased the expression of LncRNA GAPLINC. GAPLINC silence in RA-FLSs revealed significant inhibition in cell proliferation which was showed by the reduced cell number in S phase（P<0.05）. Moreover， flow cytometry assay showed GAPIINC-siRNA treatment group had an accumμLation of cells in the G0/G1 phase and decreased RA-FLSs in the S and G2/M phase（P<0.05）. After GAPLINC knockdown， mRNA and protein levels of Cyclin D1 and PCNA， which were positively correlated with proliferative phenotype， were decreased （P<0.05）， while p21， which was negatively correlated with proliferative phenotype， was up-regμLated （P<0.05）. ConclusionsThe mRNA expression of GAPLINC was higher in RA-FLSs compared with trauma-FLSs ，which was statistically significant（P<0.05）. The silence of LncRNA GAPLINC coμLd significantly inhibit RA-FLSs cell growth and suppress the cell cycle transformation， which suggests that GAPLINC may play a role in the regμLation of proliferation of RA-FLSs， leading to synovial hyperplasia and contributing to RA progression.

Abstract Objective To analyze the Prolyl 4-Hydroxylase subunit Alpha-2 (P4HA2) expression in Lung Adenocarcinoma (LAUD). Methods The authors assessed P4HA2 expression in the LUAD tumor ecosystem using single-cell analysis. The authors analyzed the relationship between P4HA2 expression and clinical features in LUAD and Brain Metastasis (BM) cases. The authors assessed the biological functions of P4HA2 using The Cancer Genome Atlas-LUAD dataset. Results P4HA2 was more highly expressed in fibroblasts than in epithelial cells in normal lung and lung adenocarcinoma tissues (p < 0.001). P4HA2 was more highly expressed in malignant epithelial cells than in fibroblasts in the BM tissue (p = 0.002). P4HA2 expression was significantly higher in female cases than in male cases (p = 0.049) and was related to lymph node metastasis (p = 0.019) and a higher TNM stage (p = 0.020). High P4HA2 expression indicated a poor prognosis and served as an independent prognostic risk factor in lung cancer. P4HA2 was mainly enriched in the extracellular matrix organization, NADH regeneration, and canonical glycolysis. P4HA2 expression was negatively correlated with naive B cells, T-cells, CD8, and activated natural killer cells, but positively correlated with CD4 memory-activated T cells, regulatory T-cells, resting dendritic cells, and dendritic cell activation. P4HA2 messenger RNA expression was correlated with programmed death-ligand 1 and cytotoxic T-lymphocyte-associated protein 4. Conclusion P4HA2 is highly expressed in LUAD tumor cells, especially for the BM subtype, and is a valuable prognostic indicator of LUAD. It may be involved in a biological activity of distant metastasis of LUAD tumor cells and serve as a potential treatment target.
ABSTRACT
Objective:To explore the relationship between executive functioning and community integration after a traumatic brain injury and to identify the main factors influencing community integration.Methods:A cross-sectional study of 30 traumatic brain injury survivors was conducted recording their gender, age, years of education, days in coma, living status and mobility. Their executive functioning was assessed using the Disorders of Executive Function Questionnaire (DEX) and the Wisconsin Card Sorting Test (WCST). Their community integration was evaluated using the Community Integration Questionnaire (CIQ). The independent correlations of demographic characteristics, life status, mobility and executive functioning with CIQ score were quantified.Results:The average total CIQ score was negatively correlated with the average WCST-RP, DEX and WCST-RPE scores, but it was positively correlated with mobility. It was also significantly correlated with life status. DEX scores and WCST-RP scores were significant independent predictors of community integration. The average CIQ family integration score was negatively correlated with days spent in a coma and significantly correlated with living status. The average CIQ social integration score was positively correlated with mobility (and negatively correlated with DEX, WCST-RP and WCST-RPE score. WCST-RP score and mobility were significant independent predictors of CIQ social integration scores. The average CIQ productive activity scores correlated negatively with the DEX, WCST-RP and WCST-RPE scores, and with the DEX and WCST-RP executive function scores. They were significant independent predictors of CIQ productive activity scores.Conclusions:Executive functioning can predict community integration, especially its social integration dimension.
ABSTRACT
To compare the incidence of hypoglycemia between day-before bowel preparation and split-dose bowel preparation in colonoscopy patients. The effects of enterald ietary nutrients on the prevention of hypoglycemia and the preparation quality of the intestine during colonoscopy were compared. The patients who underwent colonoscopy were divided into the day-before bowel preparation group, the split-dose bowel preparation group, and the split-dose bowel preparation + enteral nutrient diet group. All patients had their finger blood sugar tested before colonoscopy. The peripheral blood glucose level was measured before operation. After the endoscopic examination, the intestinal cleanliness of the patients was evaluated through the Boston intestinal preparation scale by endoscopists. The incidence of day-before bowel preparation group and split-dose bowel preparation group and enteral nutrient intervention group were 14.38%(23/160), 17.50% (28/160)and 6.45% (4/62), respectively. The proportions of high quality intestinal cleaning were 31.25% (50/160), 35.00% (56/160) and 82.26% (51/62) in the three groups respectively. The incidence of hypoglycemia was higher in split-dose bowel preparation group than that in day-before bowel preparation group. Enteral nutrient intervention can effectively reduce the incidence of hypoglycemia and improve the quality of intestinal preparation, which is a recommended intestinal preparation method.
ABSTRACT
Objective:To evaluate the prognostic accuracy of the sequential organ failure assessment (SOFA), quick sequential organ failure assessment (qSOFA) and systemic inflammatory response syndrome (SIRS) criteria in predicting the mortality in patients with infection or suspected infection by using network Meta-analysis.Methods:Five databases including Wanfang Data, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), PubMed, Web of Science were searched from February 23, 2016 to September 5, 2020 to identify the relevant literatures comparing the prognostic accuracy of two or more scores for mortality in patients with infection or suspected infection. The literatures screening, data extraction and the quality assessment of the included studies were all conducted independently by two reviewers. Stata 14.0 software was used to test the heterogeneity between the original studies of pairwise comparison of each of the three scoring systems. Ring inconsistency test was used to judge the consistency between direct comparison and indirect comparison. Then network Meta-analysis was performed and the results were ranked. The predictive ability of the three scoring systems was evaluated by surface under cumulative ranking curve (SUCRA). A "comparison-correction" funnel plot was drawn to assess whether there was publication bias in the included studies.Results:A total of 38 studies were enrolled, the overall quality was high. Network meta-analysis showed that SOFA had a great prognostic performance in predicting mortality for patients with infection or suspected infection, which was followed by qSOFA [mean difference ( MD) = 0.07, 95% confidence interval (95% CI) was 0.05-0.09] and SIRS scores ( MD = 0.16, 95% CI was 0.14-0.18), and the qSOFA score was better than SIRS score ( MD = 0.09, 95% CI was 0.07-0.11). In the order of predicting the death risk of patients with infection or suspected infection, SOFA score had higher predictive value, followed by qSOFA score, and SIRS score was the lowest, with SUCRA values of 1.0, 0.5 and 0, respectively. Funnel plot showed that all the studies were distributed on both sides of the midline, but the distribution was not symmetrical, suggesting that there was a high possibility of publication bias and small sample effect. Conclusions:SOFA score had the best prognostic performance in predicting mortality of patients with infection or suspected infection as compared with qSOFA score and SIRS score. However, the funnel plot showed that included literatures may exist small sample effects or publication bias. So the final results should be validated by more prospective studies with multicenters and large samples.
ABSTRACT
Objective:To investigate the influencing factors of nursing interns' satisfaction with having internship in third-grade class-A hospitals in Luzhou City.Methods:Using self-compiled satisfaction questionnaire and mentor's behavior scale (MBS), the internship situation of nursing interns in third-grade class-A hospitals in Luzhou City were investigated.

The MBS scores of 567 nursing interns were (3.54±0.72) and 81.1% (460/567) were satisfied with the clinical internship. The teaching mode ( OR=3.570) and the behavior of mentors ( OR=1.056) were the influencing factors of students' internship satisfaction. Conclusion:During the internship, one-to-one clinical teaching mode should be adopted in the process of internship, for improving students' internship experience. Meanwhile, teachers' behavior should be standardized to improve students' learning satisfaction and clinical teaching quality.
ABSTRACT
The classic acupuncture theory is an important component of the basic theory of TCM. Due to clinical disciplinary division and other factors, the relationship of acupuncture theory with each division of "Chinese herbal formula and pulse" has been gradually alienated. In this paper, by taking the progress of syndrome/pattern differentiation and treatment of 3 medical cases as the examples, the feasibility of clinical application of classical formulas guided by the classic acupuncture theory and clinical effect are explained. It shows that the accuracy of syndrome/pattern differentiation and the therapeutic effect can be obviously improved if the classic acupuncture theory is correctly applied to the syndrome/pattern differentiation and treatment with classical Chinese herbal formulas. It also proves the inner communication and high complementarity in terms of the theory between acupuncture and classical Chinese herbal formula. It is anticipated to provide the references for the theoretic integration among academic disciplines and for the mutual reference as well as for the application of the characteristic theories among specialties.

Objective:To detect the changes in mental arithmetic competence and the related influencing factors in patients with early Parkinson's disease(PD)by using mental arithmetic task behavioral experiment.Methods:Thirty-one patients with early PD and 40 healthy controls were enrolled in this study.The cognitive functions were tested by mini-mental state examination(MMSE)and Montreal cognitive assessment(MoCA). The differences of mental arithmetic competence between the two groups were measured by behavioral experiment.Results:There was no significant difference in correct rate, reaction time and post-corrected reaction time while performing baseline tasks and easy mental arithmetic tasks between the two groups( P>0.05). The reaction time had no significant difference between the two groups after adjusting some confounding factors( P>0.05). However, the correct rate while performing difficult mental arithmetic tasks was significantly lower( t=-2.232, P=0.029)and the reaction time was significantly longer( t=2.149, P=0.035)in PD group than in the controls, and the significant difference in reaction time persisted even after adjusting some confounding factors( t=3.139, P=0.003). In PD group, the correct rate of difficult mental arithmetic tasks was positively associated with MoCA scores( r=0.561, P=0.004), and negatively associated with age( r=-0.532, P=0.008). The reaction time and post-corrected reaction time while performing difficult metal arithmetic task were negatively associated with MoCA scores( r=-0.525, P=0.01; r=-0.554, P=0.005)and positively associated with age( r=0.485, P=0.037; r=0.514, P=0.012)in PD group. Conclusions:The difficult mental arithmetic competence is impaired in early PD patients, which is statistically significantly correlated with cognitive function and age.
ABSTRACT
@#With the development and prevalence of artificial intelligence(AI), the application of AI has become a global trend in medical field recent years. The combination of AI and clinical medicine is becoming a hot spot in medical research. It is remarkable that the AI based on deep learning(DL)has achieved great accomplishments in image recognition, speech recognition and natural language processing, especially the application of convolutional neural network(CNN)in image recognition. CNN has been applied to the detection and diagnosis of various of ophthalmological diseases such as diabetic retinopathy, retinopathy of prematurity, glaucoma and age-related macular degeneration. Meanwhile, there are many public databases on ocular including large amount of images of fundus photographs, optical coherence tomography and visual field for researchers to train and test the AI algorithms. However, training the algorithm based on AI technology is still costly and time-consuming. The medical ethic of AI is another challengefor its application. Although DL has bought revolutionary change in ophthalmology field, it still has a long way to go for its world wide application. The article aims to synthesize the researches on the applications of AI technology in ophthalmology, and give a review on the present situation, existing problems and future outlook.
ABSTRACT
ObjectiveIn cerebral ischemia, free radicals form in large quantities and activate the inflammasome nod-like recepter protein 3(NLRP3), thereby exacerbating brain damage. Edaravone has the effect of scavenging free radicals, but the relationgship between its neuroprotective effect and inflammasome NLRP3 has not been reported. To study the neuroprotective effects of edaravone on inflammasome NLRP3 and associated protein of the blood-brain barrier against cerebral ischemia injury.Methods60 male Sprague-Dawley rats were randomly divided into Sham group, cerebral embolism group and edaravone group, respectively. Rat thromboembolic MCAO models were established and edaravone (3mg/kg) was intravenous injected immediately after occlusion and 4 hours after occlusion. In the sham group, cervical blood vessels were separated only, and no embolus was injected. At 24 hours after thrombi injected, mNSS score was used to evaluate neurological function deficits. Brain infarct volume was estimated by TTC staining. The expression of inflammasome NLRP3, occludin and ZO-1 was detected by Western blot. Immunohistochemistry was used to measure IgG leakage.ResultsThe mNSS score and infarct volume of cerebral embolism group at 24 hours after stroke were significantly higher than Sham group (P<0.05). The expression of inflammasome NLRP3 in the brain increased (P<0.05), occludin and ZO-1 blood brain barrier associated protein decreased (P<0.05), and IgG leakage increased. But compared with cerebral embolism group, the mNSS score（4.50±2.12 vs 6.50±1.35, P<0.05）and infarct volume （19.29±11.92 vs 29.99±7.56, P<0.05）decreased when treated with edaravone. Edaravone treatment significantly attenuated inflammasome NLRP3 expression in cerebral ischemic area (0.97±0.47 vs 1.58±0.86, P<0.05), degradation of BBB components (occludin, ZO-1) (1.04±0.19 vs 0.53±0.09, 0.66±0.05 vs 0.30±0.04,P<0.05) and IgG leakage decreased.ConclusionInflammasome NLRP3 play an important role in acute cerebral ischemia injury. Edaravone may provide neuroprotection by inhibiting expression of inflammasome NLRP3 and degradation of associated protein of blood brain barrier.
ABSTRACT
Objective To evaluate the effects of turmeric volatile oil (TVO) combined with cisplatin on the proliferation and apoptosis of a human cutaneous squamous cell carcinoma cell line A431,and to explore their mechanisms.Methods Some cultured A431 cells at exponential growth phase were divided into several groups to be treated with 5,10,20,40 and 80 mg/L TVO,as well as high-glucose Dulbecco's modified Eagle's medium (DMEM) containing 1％ dimethyl sulfoxide (DMSO,control group),respectively.After 24-hour treatment,cell counting kit 8 (CCK8) assay was performed to estimate the proliferative activity of A431 cells in the above groups.Some other A431 cells were divided into 4 groups:control group treated with high-glucose DMEM containing 1％ DMSO,TVO group treated with 40 mg/LTVO,cisplatin group treated with 10 mg/L cisplatin,and TVO + cisplatin group treated with 40 mg/L TVO and 10 mg/L cisplatin.After 24-hour treatment,CCK8 assay was performed to estimate the cellular proliferative activity,inverted microscopy to observe changes in cell morphology,fluorescence microscopy to detect cell apoptosis after acridine orange (AO)/ethidium bromide (EB) double-staining,colorimetry to evaluate the activity of Caspase-3 and Caspase-9,and Western blot analysis to determine the protein expression of Caspase-3 and p-glycoprotein.Results After 24-hour treatment with 5,10,20,40 and 80 mg/L TVO,the cell proliferation rates were inhibited by (12.83 ± 6.4)％,(16.27 ± 11.4)％,(21.61 ± 9.1)％,(33.11 ± 2.0)％ and (46.00 ± 3.3)％ respectively,and the inhibition rates were all significantly higher in these groups than in the control group (4.03％ ± 1.4％,all P ＜ 0.05).The 50％ inhibitory concentration (IC50) of TVO at 24 hours was (61.66 ± 1.03) mg/L.Compared with the control group,the proliferation inhibition rates significantly increased in the TVO group,cisplatin group and TVO + cisplatin group (all P ＜ 0.05),suggesting that the combination of TVO and cisplatin showed synergistic inhibitory effects with a combination index of 1.366.Moreover,A431 cells turned round to different extents and became apoptotic in the TVO group and cisplatin group,and the TVO + cisplatin group showed obviously decreased number of cells and a large number of cell debris.The TVO + cisplatin group also showed significantly increased activity of Caspase-3 (1.520 ± 0.115) and Caspase-9 (2.760 ± 0.297) as well as protein expression of Caspase-3 (1.482 ± 0.016) compared with the TVO group (Caspase-3 activity:1.117 ± 0.095;Caspase-9 activity:1.259 ± 0.059;Caspase-3 protein expression:1.156 ± 0.006,all P ＜ 0.01) and cisplatin group (Caspase-3 activity:1.381 ± 0.089;Caspase-9 activity:1.829 ± 0.171;Caspase-3 protein expression:1.296 ± 0.021,all P ＜ 0.01),but significantly decreased p-glycoprotein expression (0.528 ± 0.014) compared with the TVO group (1.311 ± 0.011,P ＜ 0.01) and cisplatin group (1.169 ± 0.012,P ＜ 0.01).Conclusion TVO combined with cisplatin can synergistically inhibit the proliferation of A431 cells and induce cell apoptosis,which may be associated with activation of the caspase system and decreased expression of pglycoprotein.

ABSTRACT
Objective To investigate the indication and clinical experience of laparoscopic subtotal cholecystectomy. Methods We performed a retrospective analysis on the clinical data of 468 patients who underwent laparoscopic subtotal cholecystectomy from January 2012 to December 2015. Results There were no deaths. 7 cases that underwent laparoscopic cholecystectomy were converted to open surgery with laparoscopic subtotal cholecystectomy. 5 cases that were diagnosed with Mirizzi syndrome (3 cases with type I and 2 with type II) and 456 cases underwent laparoscopic subtotal cholecystectomy. No severe complication was detected after surgery. 16 cases with biliary leakage and 2 with duodenum leakage. The patients got recovered after a short time of drainage. 362 cases were followed up and the median follow-up time was (21.0 ± 4.9) months. 18 ones were with dyspepsia and 11 ones with upper or right upper discomfort. Conclusion Laparoscopic subtotal cholecystectomy was a safe choice and avoided injury of biliary duct for patients with severe adhesion of calot's triangle. The biliary leakage should be mainly observed during and after surgery.
