ABSTRACT

Objective: To observe the effects of acupoint thread-embedding therapy and low-carbohydrate diet therapy on obese patients with food addiction. Methods: Sixty-five eligible patients were randomized into a thread-embedding group of 33 cases and a diet group of 32 cases to respectively receive 12-week treatment. Before treatment, after treatment and at 6-month follow-up, the two groups were observed and compared in terms of body mass (BM), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), body mass index (BMI), body fat rate (BFR), basal metabolic rate (BMR) and Yale food addiction scale version 2.0 (YFAS 2.0). Results: At the end of treatment, there were no significant differences in the general efficacy, and the improvements in BM, BMI, WC, HC, WHR and BFR between the thread-embedding group and diet group (all P>0.05). At follow-up, the thread-embedding group showed more significant improvements in all the aforementioned indicators compared with the diet group except HC (all P<0.05). At the end of treatment and follow-up, BMR and YFSA 2.0 had more significant improvements in the thread-embedding group than in the diet group (all P<0.05). Conclusion: Acupoint thread-embedding therapy can produce significant efficacy in treating obese patients with food addiction; it can improve the food addiction state and work better in maintaining the efficacy compared with low-carbohydrate diet therapy.

ABSTRACT

Objective:1. To detect any change in the PTEN/Akt/FoxO1 signaling pathway in the muscles of rats with chronic hypoxia-hypercapnia treated using neuromuscular electrical stimulation (NMES), and 2. To document the role of chronic hypoxia-hypercapnia in inducing muscle atrophy.Methods:Thirty-two male Sprague-Dawley rats were randomly divided into a control group, a model group, a mock stimulation group, and an NMES group, each of eight. All of the rats in the model group, the mock stimulation group and the NMES group were placed in a hypoxia-hypercapnia chamber with a 9-11% O 2 and 5.5-6.5% CO 2 atmosphere for 8h per day and 7d per week, lasting 4 weeks. The control group were placed in a similar chamber with normal air. In the last 2 weeks, after the 8h in the chamber, the NMES group were given 30min of electrical stimulation at 100Hz to the calf muscles of their bound lower limbs. The mock stimulation group were only bound without any electrical stimulation. After the 4-week intervention, the gastrocnemius muscles were resected and their cross-sectional areas (CSAs) were observed using hematoxylin-eosin staining. Immunohistochemistry and western blotting were employed to detect the protein expression of phosphatase and tensin (PTEN), p-Akt, Akt and FoxO1. Results:Compared with the control group, a significant decrease was observed in the average CSA and in the expression of p-Akt and Akt in the model group, while a significant increase was found in the average protein expression of PTEN and FoxO1. Compared with the model group, there was a significant increase in the average CSA, as well as the average expression of p-Akt and Akt in the NMES group, but a significant decrease in the average expression of PTEN and FoxO1.Conclusion:Neuromuscular electrical stimulation can relieve muscle atrophy from chronic hypoxia-hypercapnia by inducing skeletal muscle protein synthesis through regulating the PTEN/Akt/FoxO1 signaling pathway, at least in rats.

ABSTRACT

Objective:The aim of this study was to analyze the relationship between the changes of pre- and post-operation PET/CT metabolic parameters and prognosis for liver cancer patients.Methods:A retrospective study was carried out among 92 patients with liver cancer who received liver transplantation and PET/CT examination in our hospital from October 2013 to May 2017.According to Deauville criteria, the lesions were classified into PET negative, weak positive, and strong positive. The metabolic parameters including SUV max, SUL, MTV, TMR, TLR, TLG, UVP of normal liver parenchyma, liver cancer lesions and mediastinum were measured or calculated. The relationship between metabolic parameters and recurrence was analyzed. The relationship of Deauville score and metabolic parameters and the changing characters of metabolic parameters between the PET/CT of pre and post transplantation were analyzed. Results:Thirty cases did not relapse after LT, among which 16, 7 and 7 cases had Deauville score of 3, 4 and 5 respectively in pre-operation PET/CT. The recurrence time of 62 patients in recurrence group was (10.90±10.30) months. MTV, TLG, UVP-M, UVP-LB in recurrence group were significant higher( P<0.05). Patients with low metabolic parameters show better prognosis than patients with high metabolic parameters. Metabolic parameters of 5 score group were higher than that of 4score. The metabolic parameters of recurrence group were higher than those in non-recurrence group. MTV, TLG, UVP-M, UVP-LB in post-operation PET/CT were lower than those in pre-operation PET/CT, however, SUV max, TMR, TLR, SUL had no significantly difference. Conclusions:PET/CT metabolic burden parameters should be evaluated before LT to select patients with better prognosis. For liver transplantation patients with high metabolic parameters, PET/CT examination should be performed early after surgery to improve the detection of recurrence and metastasis, and relevant treatment should be timely conducted.

ABSTRACT

Objective:To explore relationship between serum 25-hydroxy vitamin D ( 25OHD ) level and ketosis-prone in patients with newly-diagnosed type 2 diabetes mellitus(T2DM).Methods:One hundred and thirty-four patients with newly diagnosed T2DM (103 males, 31 females) admitted in The Third Affiliated Hospital, Southern Medical University from January 2017 to January 2019 were enrolled into this study, including 36 patients with ketosis-prone (KPDM group) and 98 patients without ketosis(NKPDM group). Clinical characteristics, including height, weight, and history of hypertensive disease were collected. Serum 25OHD levels, lipid profile, islet function and glycosylated hemoglobin (HbA 1C)levels, ICA, IAA, GAD-Ab, etc., were measured. Results:Among the 134 patients, the patients with vitamin D deficiency, insufficiency, and sufficiency were 71 cases(52.99%), 52 cases(38.81%), and 11 cases(8.20%), respectively. KPDM group had significantly lower serum 25OHD level than NKPDM group[(44.12±9.77) nmol/L vs (55.35±15.31) nmol/L, P<0.01]. The rate of vitamin D deficiency was significantly higher in KPDM group compared to that in NKPDM group [(77.78% vs 43.88%), P<0.01]. The prevalence of KPDM varied significantly in different vitamin D status groups( P<0.01). Logistic regression analysis suggested that low serum 25OHD, younger age, high HbA 1C, and triglyceride were risk factors to ketosis-prone in newly diagnosed T2DM( P<0.01). Conclusion:Vitamin D deficiency is a common problem in newly diagnosed T2DM, especially in KPDM. Low serum 25OHD level seems to be an independent risk factor for ketosis-prone in patients with newly diagnosed T2DM.

ABSTRACT

Objective:To investigate the effect of fine anatomy combined with exposure of recurrent laryngeal nerve in cricothyroid space in differentiated thyroid cancer surgery.Methods:Sixty patients with differentiated thyroid cancer who received treatment in Ningbo Hospital of Traditional Chinese Medicine from January 2017 to April 2020 were included in this study. They were randomly assigned to receive either fine anatomy combined with exposure of recurrent laryngeal nerve in cricothyroid space (observation group, n = 30) or routine surgery + inferior thyroid artery exposure of recurrent laryngeal nerve (control group, n = 30). Operative time, the volume of intraoperative blood loss, and the number of lymph node dissected were compared between the two groups. Parathyroid hormone (PTH) and blood calcium (Ca 2+) concentrations in the two groups were determined. The adverse reactions such as recurrent laryngeal nerve and parathyroid injury were observed in each group. Results:Operative time, the volume of intraoperative blood loss, and the number of lymph node dissected in the observation group were (71.28 ± 10.08) minutes, (16.69 ± 4.65) mL, and (4.78 ± 1.26), respectively, which were significantly different from those in the control group [(69.27 ± 11.89) minutes, (17.14 ± 4.52) mL, (4.76 ± 1.22), t = 0.706, 0.380, 0.062, all P > 0.05]. Before surgery, there were no significant differences in PTH and Ca 2+ concentrations between the two groups [PTH: (50.24 ± 11.21) g/L vs. (50.21 ± 11.19) g/L; Ca 2+: (2.18 ± 0.08) mmol/L vs. (2.17 ± 0.09) mmol/L, t = 0.010, 0.454, both P > 0.05]. After surgery, PTH and Ca 2+ concentrations in the observation group were significantly higher than those in the control group [PTH: [(31.44 ± 6.09) g/L vs. (16.57 ± 2.35) g/L; Ca 2+: (2.07 ± 0.10) mmol/L vs. (1.23 ± 0.12) mmol/L, t = 12.477, 29.454, both P < 0.01]. Total incidence of adverse reactions in the observation group was significantly lower than that in the control group [10.00% (3/30) vs. 46.67% (14/30), χ2 = 9.931, P < 0.01). Conclusion:Application of fine anatomy combined with exposure of recurrent laryngeal nerve in cricothyroid space in differentiated thyroid cancer surgery is highly effective in the clinic. Accurate identification of recurrent laryngeal nerve in cricothyroid space is helpful to preserve the parathyroid gland and blood supply in situ, leads to a small range of changes in PTH and Ca 2+ concentrations, reduces postoperative complications, so as to protect the recurrent laryngeal nerve and parathyroid gland and thereby promote postoperative recovery.

ABSTRACT

In May 2018, the World Health Organization (WHO) called for the "global elimination of cervical cancer" and China committed to join 194 countries worldwide to "eliminate cervical cancer". In November 2020, WHO released the Global Strategy for Accelerating the Elimination of Cervical Cancer, specifying the 2030 strategic goal. China has a large population, which makes the task of eliminating cervical cancer difficult. Based on the global and local burden of cervical cancer,we discussed the current situation of cervical cancer in China in the achievement of the elimination. We showed that in order to achieve the phased elimination goal of cervical cancer by 2030, the supply of HPV vaccine needs to increase by 38% every year, the HPV vaccination coverage needs to increase by 45% every year, and the screening coverage of cervical cancer in appropriate-aged women needs to increase by 10% every year. In conclusion, efforts should be made to expand cervical cancer screening, and to incorporate HPV vaccination into the national immunization program.

ABSTRACT

Objective:To systematically review the effectiveness of pediatric wheelchairs on the function of children with disabilities. Methods:Literatures about clinical application of pediatric wheelchairs were researched from the PubMed, Web of Science, Embase, Cochrane Library, EBSCO (CINAHL), CNKI, Wanfang Database and VIP Database, till February, 2021. The clinical application effectiveness of pediatric wheelchairs was extracted and analyzed by inductive approach. Results:A total of ten case studies, one randomized controlled study and one cohort study were included, and quality assessment showed low quality. There were different types of pediatric wheelchairs for all ages over twelve months and different disease types of children, mostly for cerebral palsy. The review showed that pediatric wheelchairs mainly improved the motor function of disabled children, promoted the development of cognitive functions, and improved activities and participation abilities. The wheelchairs could be individually adapted to manual wheelchairs, electric wheelchairs and smart wheelchairs, according to the individual conditions of the children, with additional postural support devices for adaptive transformation. Conclusion:Pediatric wheelchairs can be used to improve the function and quality of life of children with disabilities. Although functional rehabilitation effects of pediatric wheelchairs have shown a promising trend, most of the current studies are case reports, and there is a lack of high-quality clinical control studies, and the unified adaptation standard has not been established yet.

ABSTRACT

Lung cancer despite advancement in the medical field continues to be a major threat to human lives and accounts for a high proportion of fatalities caused by cancers globally. The current study investigated vanillin oxime, a derivative of vanillin, against lung cancer cells for development of treatment and explored the mechanism. Cell viability changes by vanillin oxime were measured using MTT assay. Vanillin oxime-mediated apoptosis was detected in A549 and NCI-H2170 cells at 48 h of exposure by flow cytometry. The CEBP homologous protein (CHOP) and death receptor 5 (DR5) levels were analysed by RT-PCR and protein levels by Western blotting. Vanillin oxime in concentration-dependent way suppressed A549 and NCI-H2170 cell viabilities. On exposure to 12.5 and 15 μM concentrations of vanillin oxime elevated Bax, caspase-3, and -9 levels in A549 and NCI-H2170 cells were observed. Vanillin oxime exposure suppressed levels of Bcl-2, survivin, Bcl-xL, cFLIP, and IAPs proteins in A549 and NCI-H2170 cells. It stimulated significant elevation in DR4 and DR5 levels in A549 and NCI-H2170 cells. In A549 and NCI-H2170 cells vanillin oxime exposure caused significant (p < 0.05) enhancement in CHOP and DR5 mRNA expression. Vanillin oxime exposure of A549 and NCI-H2170 cells led to significant (p < 0.05) enhancement in levels of phosphorylated extracellular-signal-regulated kinase and c-Jun N-terminal kinase. Thus, vanillin oxime inhibits pulmonary cell proliferation via induction of apoptosis through tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) mediated pathway. Therefore, vanillin oxime may be studied further to develop a treatment for lung cancer.

ABSTRACT

Colorectal cancer is a malignancy with high mortality. Huangqin Tea(HQT) can exert potential preventive and therapeutic effects on colorectal cancer. Flavonoids are the main compounds in HQT, but the pharmacodynamic material basis and mechanism are unclear. Network pharmacology and molecular docking were used to predict and analyze the targets and signaling pathways of HQT in the prevention and treatment of colorectal cancer. The active components of flavonoids in HQT were searched and screened out by literature review and FAFDrugs4. The related targets of active components were predicted by SwissTargetPrediction, STITCH, and TCMSP. Colorectal cancer-related genes were collected from OMIM, TTD, and GeneCards. The common targets were obtained as the potential targets of HQT in the prevention and treatment of colorectal cancer. Metascape was used for GO function enrichment and KEGG pathway enrichment analyses. Cytoscape was used to construct the protein-protein interaction(PPI) network and "component-target-disease-pathway" network to obtained and analyze core targets and key components. AutoDock Vina was used for molecular docking verification of key components and core targets. The results showed that apigenin, luteolin, wogonin, and baicalein were presumedly the key active components in the prevention and treatment of colorectal cancer, and core targets included TP53, AKT1, VEGFA, PIK3 CA, and SRC. The key KEGG signaling pathways mainly involved PI3 K-AKT, AGE-RAGE, p53, NF-κB, Wnt, Hippo, and calcium signaling pathways. Further molecular docking results showed that four key components showed strong hydrogen bonding ability with the five core targets. This study preliminarily reveals the pharmacodynamic material basis and potential mechanism of HQT in the prevention and treatment of colorectal cancer and provides a theoretical and scientific basis for the application of HQT.

ABSTRACT

Objective:To investigate the effect of JAK2 V617F gene mutation status and burden on BCR-ABL-negative myeloproliferative neoplasms (MPN).Methods:Clinical data of 199 patients with MPN in Cangzhou Central Hospital in Hebei Province from September 2015 to January 2020 were retrospectively analyzed, and the correlations of JAK2 V617F gene mutation burden with clinicopathological features and prognostic score of MPN patients were analyzed.Results:Of the 199 BCR-ABL-negative MPN patients, 138 patients (69.4%) were positive for JAK2 V617F mutation; of these patients, 64 (88.9%) of 72 patients with polycythemia vera (PV) were mutation-positive, 54 (53.5%) of 101 patients with essential thrombocytosis (ET) were positive, 20 (80.0%) of 25 patients with myelofibrosis (MF) were mutation-positive, and 1 patient with hypereosinophilic syndrome (HES) was mutation-positive. About 55.1% (76/138) of patients had a high JAK2 V617F mutation burden. The mutation burden in PV group was the highest, MF was the second, and ET was the lowest; the mutation burdens in these three groups were (73.9±18.3)%, (59.9±25.2)% and (25.0±16.5)%, respectively. Mutation burden was positively correlated with the white blood cell counts of patients with PV, ET and MF ( r values were 0.626, 0.675 and 0.796, all P < 0.01). JAK2 V617F mutation burden was positively correlated with the prognostic scores of patients with PV and ET ( r values were 0.296 and 0.404, both P < 0.05). Conclusion:The JAK2 V617F mutation burden of BCR-ABL-negative MPN patients is related to clinicopathological factors, and the prognosis of patients with high JAK2 V617F mutation burden is poor.

ABSTRACT

Paris saponin VII (PSVII), a bioactive constituent extracted from Trillium tschonoskii Maxim., is cytotoxic to several cancer types. This study was designed to explore whether PSVII prevents non-small-cell lung cancer (NSCLC) proliferation and to investigate its molecular target. AMP-activated protein kinase (AMPK) has been implicated in the activation of autophagy in distinct tissues. In cultured human NSCLC cell lines, PSVII induces autophagy by activating AMPK and inhibiting mTOR signaling. Furthermore, PSVII-induced autophagy activation was reversed by the AMPK inhibitor compound C. Computational docking analysis showed that PSVII directly interacted with the allosteric drug and metabolite site of AMPK to stabilize its activation. Microscale thermophoresis assay and drug affinity responsive target stability assay further confirmed the high affinity between PSVII and AMPK. In summary, PSVII acts as a direct AMPK activator to induce cell autophagy, which inhibits the growth of NSCLC cells. In the future, PSVII therapy should be applied to treat patients with NSCLC.

ABSTRACT

Objective:To investigate the number of necroptotic renal tubular epithelial cells in renal tissues of patients with chronic kidney disease (CKD) and the correlation with clinicopathologic parameters, and explore its role in the progression of the excessive loss of renal tubular cells and chronic kidney injury.Methods:Renal tissue samples from 60 patients (18-65 years old) with CKD proven by kidney biopsy in the First Affiliated Hospital of Hainan Medical University from June 2017 to June 2019 were collected. According to internationally accepted K/DOQI guidelines, the patients were divided into 1-4 stages of CKD, with 15 cases in each stage. The number of necroptotic renal tubular epithelial cells in patients with different stages of CKD was detected using receptor-interacting protein 3 (RIP3) and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) fluorescent staining, and the expression of RIP3 and MLKL, marker protein of necroptosis, was detected by immunohistochemistry. Pearson correlation analysis was used to analyze the correlation between the percentage of necroptotic renal tubular epithelial cells and clinicopathologic parameters. In addition, the expression of angiotensinogen Ⅱ receptor (AT2R) in renal tissue and its correlation with the percentage of necroptotic renal tubular epithelial cells were analyzed.Results:With the development of CKD, the structural destruction of renal tubules in patients with CKD was gradually aggravated, and the renal tubules in the corresponding areas were atrophied, accompanied by worsening interstitial fibrosis. The adjacent renal tubules were focally dilated and numerous protein tubules were seen in the tubules. Importantly, renal tubular injury score in second and third stage of CKD was significantly higher than that in control group (both P<0.01). TUNEL+RIP3 immunofluorescence staining results showed that the percentage of TUNEL/RIP3 double positive renal tubular epithelial cells (necroptotic renal tubular epithelial cells) in renal tubules of the second and third stage of CKD was higher (all P<0.01). Immunohistochemical results showed that RIP3, MLKL and AT2R proteins were mainly expressed in cytoplasm of renal tubular epithelial cells, and the expression of RIP3, MLKL and AT2R in renal tubular epithelial cells was higher in the second and third stage of CKD patients (all P<0.05). Pearson correlation analysis showed that the percentage of necroptotic renal tubular epithelial cells was positively correlated with blood urea nitrogen ( r=0.514, P=0.003), serum creatinine ( r=0.507, P=0.019), serum cystatin C ( r=0.571, P=0.026), serum uric acid ( r=0.592, P=0.008), renal tubules injury score ( r=0.901, P<0.001), renal interstitial fibrosis index ( r=0.700, P=0.001) and the expression of AT2R protein in renal tissue ( r=0.715, P=0.001). Conclusions:As CKD progresses, necroptosis of renal tubular epithelial cells in CKD patients occurs. The necroptotic cell death may be an important factor leading to renal tubular epithelial cell excessive death and the progression of chronic kidney injury. Furthermore, necroptosis of renal tubular epithelial cells may be related to the high expression of AT2R in kidney tissue.

ABSTRACT

Objective:To visualize the research hot spots and frontiers of non-surgical treatments for idiopathic scoliosis (IS) based on CiteSpace.Methods:The Web of Science Core Database and China National Knowledge Infrastructure from 1990 to 2020 were searched for studies of non-surgical treatments of idiopathic scoliosis. The time, distributions of nations, institutions, academic disciplines and keywords of literature were analyzed. With CiteSpace 5.7.R4 and Excel 2017, the visualized knowledge graphs and the data tables were generated.Results:A total of 822 studies including 548 articles in English and 274 articles in Chinese were retrieved, including 378 articles published during 2015—2020. The top three nations with higher number of published articles were USA (114 studies), Canada (77 studies) and China (68 studies). Studies covered 33 disciplines, including rehabilitation, engineering and orthopedics, and the betweenness centrality of rehabilitation medicine was the highest (0.59). The non-surgical treatment research was focused on adolescents (187 studies) and brace treatment (116 studies). From 1990 to 2014, the non-surgical treatment of IS mainly focused on the brace treatment (70.4%,69/98) in domestic studies. After 2014, comprehensive treatments such as exercise therapy and manual therapy gradually became the research trend in this field (61.3%,92/150). Research hotspots included different forms of brace treatment (betweenness centrality: 0.31), exercise (6 studies), manual therapy (3 studies), guide of medicine (2 studies), acupuncture therapy (2 studies) of non-surgical treatments. Among top 30 research institutions for domestic publication of Chinese literature, there were 22 tertiary hospitals, 1 secondary hospital, 5 schools, 1 comprehensive rehabilitation service organization, and 1 community health service center.Conclusion:The research content of non-surgical treatment for idiopathic scoliosis tends to be diversified, comprehensive treatment of exercise therapy, brace therapy, and manual therapy are currently the main research hotspots.

ABSTRACT

Objective:In general, patients with seropositive rheumatoid arthritis (RA) are considered to show an aggressive disease course. However, the relationship between the two subgroups in disease severity is controversial. Our study is aimed to compare the clinical characteristics and prognosis of double-seropositive and seronegative RA in China through a real-world large scale study.Methods:RA patients who met the 1987 American College of Rheumatology (ACR) classification criteria or the 2010 ACR/European Anti-Rheumatism Alliance RA classification criteria, and who attended the 10 hospitals across the country from September 2015 to January 2020, were enrolled. According to the serological status, patients were divided into 4 subgroups [rheumatoid factor (RF)(-) anti-cyclic citrullinated peptide (CCP) antibody (-), RF(+), RF(+) anti-CCP antibody(+), anti-CCP antibody(+)] and compared the disease characteristics and treatment response. One-way analysis of variance was used for measurement data that conformed to normal distribution, Kruskal-Wallis H test was used for measurement data that did not conform to normal distribution; paired t test was used for comparison before and after treatment within the group if the data was normally distributed else paired rank sum test was used; χ2 test was used for count data. Results:① A total of 2 461 patients were included, including 1 813 RF(+) anti-CCP antibody(+) patients (73.67%), 129 RF(+) patients (5.24%), 245 RF(-) anti-CCP antibody(-) patients (9.96%), 74 anti-CCP antibody(+) patients (11.13%). ② Regardless of the CCP status, RF(+) patients had an early age of onset [RF(-) anti-CCP antibody(-) (51±14) years old, anti-CCP antibody(+) (50±15) years old, RF(+) anti-CCP antibody(+) (48±14) years old, RF(+)(48±13) years old, F=3.003, P=0.029], longer disease duration [RF(-) anti-CCP antibody(-) 50 (20, 126) months, anti-CCP antibody(+) 60(24, 150) months, RF(+) anti-CCP antibody(+) 89(35, 179) months, RF(+) 83(25, 160) months, H=22.001, P<0.01], more joint swelling counts (SJC) [RF(-) anti-CCP antibody(-) 2(0, 6), Anti-CCP antibody(+) 2(0, 5), RF(+) anti-CCP antibody(+) 2(0, 7), RF(+) 2(0, 6), H=8.939, P=0.03] and tender joint counts (TJC) [RF(-) anti-CCP antibody(-) 3(0, 8), anti-CCP antibody(+) 2(0, 6), RF(+) anti-CCP antibody(+) 3(1, 9), RF(+) 2(0, 8), H=11.341, P=0.01] and the morning stiff time was longer [RF(-) anti-CCP antibody(-) 30(0, 60) min, anti-CCP antibody(+) 20(0, 60) min, RF(+) anti-CCP antibody(+) 30(10, 60) min, RF(+) 30(10, 60) min, H=13.32, P<0.01]; ESR [RF(-) anti-CCP antibody(-) 17(9, 38) mm/1 h, anti-CCP antibody(+) 20(10, 35) mm/1 h, RF(+) anti-CCP antibody(+) 26(14, 45) mm/1 h, RF(+) 28(14, 50) mm/1 h, H=37.084, P<0.01] and CRP [RF(-) anti-CCP antibody(-) 2.3 (0.8, 15.9) mm/L, Anti-CCP antibody(+) 2.7(0.7, 12.1) mm/L, RF(+) anti-CCP antibody(+) 5.2(1.3, 17.2) mm/L, RF (+) 5.2(0.9, 16.2) mm/L, H=22.141, P<0.01] of the RF(+)patients were significantly higher than RF(-) patients, and RF(+) patients had higher disease severity(DAS28-ESR) [RF(-) anti-CCP antibody(-) (4.0±1.8), anti-CCP antibody(+) (3.8±1.6), RF(+) anti-CCP antibody(+) (4.3±1.8), RF(+) (4.1±1.7), F=7.269, P<0.01]. ③ The RF(+) anti-CCP antibody(+) patients were divided into 4 subgroups, and it was found that RF-H anti-CCP antibody-L patients had higher disease severity [RF-H anti-CCP antibody-H 4.3(2.9, 5.6), RF-L anti-CCP antibody-L 4.5(3.0, 5.7), RF-H anti-CCP antibody-L 4.9(3.1, 6.2), RF-L anti-CCP antibody-H 2.8(1.8, 3.9), H=20.374, P<0.01]. ④ After 3-month follow up, the clinical characteristics of the four groups were improved, but there was no significant difference in the improvement of the four groups, indicating that the RF and anti-CCP antibody status did not affect the remission within 3 months. Conclusion:Among RA patients, the disease activity of RA patients is closely related to RF and the RF(+) patients have more severe disease than RF(-) patients. Patients with higher RF titer also have more severe disease than that of patients with low RF titer. After 3 months of medication treatment, the antibody status does not affect the disease remission rate.

ABSTRACT

Objective:To find out the problems still existing in the teaching reform through the investigation and research of eight-year program graduates of clinical medicine.Methods:In 2017, 118 questionnaires were issued to Batch 2005-2006 graduates of eight-year program in clinical medicine, and 103 valid questionnaires were retrieved. The questionnaire was based on that of the Fuyi Design of the Education Department in Zhongshan Hospital affiliated to Fudan University. The questionnaire was revised on the basis of the pre-survey and the statistical analysis was carried out on the data using Excel 2010.Results:We found that 60.2% of the graduates were satisfied with the training mode of eight-year program, 69.9% of the graduates gave a satisfactory evaluation on the teaching quality in the teaching hospital, and 63.1% of the graduates believed that the curriculum still need partial adjustment.Conclusion:Based on the finding, medical talent training mode is relatively mature in Batch 2005-2006 eight-year program of clinical medicine. The future medical education reform of the eight-year program should be more embodied in innovating the grafting mode of professional medical degree system, strengthening enrollment publicity, adopting diversified enrollment, strictly controlling procedure, carrying out integrated curriculum reform, enhancing clinical teaching design, at the same time further improving teachers' comprehensive quality, and speeding up the construction of clinical teaching staff.
