ABSTRACT

Objective To quantitatively study the influence of changes in probe position on the quality control test results of dental panoramic radiography and to provide a reference for analyzing the sources of deviations in quality control test results. Methods Eight different models of dental panoramic X-ray machines were selected for this study. The film analysis method was used to determine the position of the central axis of the main beam on the image detector. The position of the probe was accurately controlled through an auxiliary moving device. The tube voltage, radiation output, and half-value layer of the useful beam were measured for positions at the center of the beam; 1 cm upward, downward, left, and right from the center of the beam; and 2 cm upward, downward, left, and right from the center of the beam. Results The tube voltage, radiation output, and half-value layer had a maximum value at the center of the beam, with a decrease in the value as the position deviated from the center. There were significant differences in the probe position sensitivity between different models of dental panoramic radiography equipment. A 2 cm deviation in the probe position resulted in an impact on the measured tube voltage of less than 5.3 kV (5.8%) for less sensitive equipment. A 2 mm deviation in the probe position resulted in an impact on the measured tube voltage of less than 5.4 kV (6.0%) for sensitive equipment. Conclusion The probe position can lead to deviation in the quality control test results of dental panoramic photography. Therefore, determining the position of the central axis of the main beam on the image detector for accurate positioning of the probe is crucial for quality control testing.

ABSTRACT

Objective To investigate the change in interleukin-33 (IL-33) in the peripheral blood of hepatocellular carcinoma (HCC) patients and the role and potential mechanism of IL-33 in regulating CD8 + T cell function in HCC patients. Methods A total of 44 HCC patients who attended Shaanxi Provincial People's Hospital from April 2019 to January 2020 and 20 healthy controls were enrolled. Peripheral blood was collected, and plasma and peripheral blood mononucleated cells (PBMCs) were isolated; ELISA was used to measure the plasma levels of IL-33 and its receptor ST2, and quantitative real-time PCR was used to measure the relative mRNA expression levels of IL-33 and ST2 in PBMCs. CD8 + T cells were purified and stimulated with recombinant IL-33; CCK-8 assay was used to assess cell proliferation, enzyme-linked immunospot assay was used to measure the secretion of perforin and granzyme B, and flow cytometry was used to measure the expression of PD-1, LAG-3, and CTLA-4; changes in cell proliferation, secretion of cytotoxic molecules, and immune checkpoint molecules after IL-33 stimulation were compared. CD8 + T cells were co-cultured with HepG2 cells; the expression of lactate dehydrogenase was measured to calculate the proportion of dead HepG2 cells induced by CD8 + T cells, and the change in the killing function of CD8 + T cells after IL-33 stimulation was compared. The t -test or the paired t -test was used for comparison of continuous data between two groups, and a Pearson correlation analysis was performed. Results Compared with the control group, the HCC group had significantly lower plasma level of IL-33 (269.80±63.08 pg/ml vs 339.50±64.43 pg/ml, t =4.072, P 0.05). The proportion of CD8 + T cells was not correlated with the plasma level of IL-33 or ST2 (both P > 0.05). Compared with the control group, the HCC group had significantly lower levels of perforin and granzyme B (both P 0.05), but it promoted the secretion of perforin and granzyme B ( P < 0.05). Compared with the control group, the HCC group had a significant reduction in the killing activity of CD8 + T cells ( P < 0.05), and stimulation with recombinant IL-33 enhanced the killing function of CD8 + T cells, which was mainly reflected in the increases in the proportion of dead HepG2 cells ( P < 0.05) and the secretion of IFNγ and TNFα ( P < 0.05). Conclusion There is a reduction in the plasma level of IL-33 in HCC patients. IL-33 can enhance the killing activity of CD8 + T cells by promoting the secretion of perforin and granzyme B, which provides a new target for the treatment of HCC.

ABSTRACT

Objective:To investigate the effect of arthroscopically-assisted open reduction and internal fixation of intra-articular distal radius fracture.Methods:A retrospective cohort study was made on clinical data of 44 patients with distal radial intraarticular fracture admitted to Jing′an District Central Hospital, Fudan University between June 2017 and August 2020. There were 13 males and 31 females, at age of 35-85years [(62.5±12.9)years]. According to AO/OTA fracture classification system, there were 7 patients with type B and 37 with type C. Open reduction and internal fixation with volar plate was used in all patients, among which 22 were operated on using arthroscopy assistance (arthroscopy group) and 22 were operated on with traditional intraoperative fluoroscopy (fluoroscopy group). The operation time in both groups and triangular fibrocartilage complex (TFCC) injury and fracture displacement in arthroscopy group were recorded. Patient-rated wrist evaluation (PRWE) score, disabilities of the arm, shoulder and hand (DASH) questionnaire and range of wrist motion were compared between the two groups at 12 months after operation. The incidence of complications was observed.Results:All patients were followed up for 12-15 months [(13.3±1.1)months]. The operation time in arthroscopy group was (104.0±40.5)minutes, longer than (71.3±32.1)minutes in fluoroscopy group ( P<0.05). In arthroscopy group, 14 patients (64%) with TFCC injury were diagnosed intraoperatively, with the fracture displacement gap and step for 0.8 (0.3, 0.8)mm and 1.0 (0.3, 1.5)mm under arthroscopic vision, which were reduced to 0.3 (0.0, 0.5)mm and 0.5 (0.0, 0.5)mm after arthroscopically-assisted reduction (all P<0.05). The PRWE score in arthroscopy group was (9.8±4.9)points at 12 months after operation, lower than (13.4±5.8)points in fluoroscopy group ( P<0.05). The DASH questionnaire in arthroscopy group was (9.0±5.0)points at 12 months after operation, lower than (13.0±6.1)points in fluoroscopy group ( P<0.05). The dorsal extension and posterior rotation of the wrist in arthroscopy group were (73.8±8.9)° and (82.5±8.0)°, higher than (65.8±14.2)° and (76.3±10.4)° in fluoroscopy group (all P<0.05). There were no postoperative complications such as loosened or broken screws, vascular nerve damage, incision infection or traumatic arthritis in both groups. Conclusion:Arthroscopic-assisted open reduction and internal fixation of intra-articular distal radius fracture can increase the accuracy of joint surface reduction, improve postoperative wrist function and confirm the diagnosis of TFCC injury during operation.

ABSTRACT

Traditional methods of non-contact human respiratory rate measurement usually require complex devices or algorithms. Aiming at this problem, a non-contact respiratory rate measurement method based on only the RGB video information was proposed in this paper. The method consisted of four steps. Firstly, spatial filtering was applied to each frame of the input video. Secondly, a gray compensation algorithm was used to compensate for the gray level change caused by the environmental light. Thirdly, the gray levels of each pixel over time were filtered separately by a low-pass filter. Finally, the region of interest was determined based on the filtering results, and the respiration rate of the human is measured. The physical measurement experiments were designed, and the measurement accuracy was compared with that of the biological radar. The error of the proposed method was between - 5.5% and 3% in different detection directions. The results show that the non-contact respiration rate measurement method can effectively measure the human respiration rate.

ABSTRACT

In consideration of the population aging and growing demands for elderly health care, medical institutions in China are faced with severe challenges. Medical knowledge, given its potential to guide clinical practice, cannot apply to clinical practice directly, and a synergy research network should be built among diversified organizations instead. Authors of this paper described the roadblocks against building a medical synergy network, and presented the experiences of Huashan Hospital, Fudan University in its exploration and development of National Clinical Research Center for Aging and Medicine. In view of major setbacks such as the absence of the following factors, namely the trust towards medical evidences produced in other facilities, a trans-organizational information sharing system, a referral procedure, clear requirements at hospital management level, and a well-functioning reimbursement mechanism. Hence the hospital is required to enhance its functionality of clinical research and play a more active role in the clinical research eco-system.

ABSTRACT

Objective To explore the correlation between acute infarctions in different parts of the brain and the risk of vascular cognitive impairment (VCI). Methods 212 patients with acute cerebral infarction were tested using Mini Mental State Examination(MMSE)and Montreal cognitive assessment(MoCA),and were divid-ed into normal cognition group,VCI group,vascular dementia group,and mixed dementia group. We analyzed the gender,age,past medical history,personal history,MMSE and MoCA scores,and imaging data. Results Of the 212 patients,61(28.77%)had normal cognition level,74(34.91%)had VCI,56(26.42%)had vascular demen-tia,and 21(9.91%)had mixed dementia. Multiple regression analysis showed that frontal lobe infarct increased the risk of VCI(OR,41.72)and vascular dementia(OR,48.49);cerebellar infarction also increased the risk of vascular dementia(OR,4.70)and mixed dementia(OR,12.38);and temporal lobe infarction increased the risk of mixed dementia significantly(OR,56.98). Conclusions Approximately 71.3%of the patients with acute cere-bral infarction develop vascular cognitive impairment. The infarcts occurring in the frontal lobe ,temporal lobe and cerebellum increase the risk of VCI significantly ,which should be given interventional therapies.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the expression level of high mobility group box-1 (HMGB1) in human colorectal cancer and its relation with different clinicopathological characteristics and prognosis of colorectal cancer patients.</p><p><b>METHODS</b>Immunohistochemical method was used to detect the HMGB1 expression in tissue samples of 86 colorectal cancer patients and 32 normal colorectal tissue samples. Positive rates of HMGB1 expression were compared among different clinicopathological characteristics. Relation of HMGB1 expression with survival was analyzed.</p><p><b>RESULTS</b>HMGB1 expression was mainly in colorectal cancer cell nucleus, with a few appearance of co-expression in nucleus and cytoplasm. Positive rate of HMGB1 expression in normal tissues was significantly lower than that in colorectal cancers [9.4% (3/32) vs. 66.3% (57/86), P=0.000], and it was much higher in large cancers, lower differentiation, invasion to outside serosa, advanced clinical stage and lymph node metastasis (all P<0.05), but was similar in terms of age and gender (P>0.05). Survival analysis showed that 3-year survival rate of patients with positive HMGB1 expression was significantly lower as compared to those with negative HMGB1 expression (56.1% vs. 85.7%, P=0.021), meanwhile it was significantly lower in patients with co-expression in nucleus and cytoplasm as compared to those with simple nuclear expression (41.4% vs. 75.0%, P=0.013).</p><p><b>CONCLUSIONS</b>HMGB1 expression in colorectal cancer is high, and its positive rate increases with the low differentiation, invasion and metastasis. HMGB1 co-expression in nucleus and cytoplasm indicates poor prognosis of colorectal cancer patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To inquire into the influence of silencing HMGB1 expression by small interfering RNA (siRNA) on cell growth, proliferation, invasion and metastasis of colorectal cancer LoVo cells both in vitro and in vivo.</p><p><b>METHODS</b>Lentivirus-mediated HMGB1 siRNA was transfected into LoVo cells to silence the HMGB1 expression. The HMGB1 mRNA and protein expression after siRNA transfection was detected by RT-PCR and Western blot. MTT assay was used to observe the cell proliferation and to draw a growth curve. Cell cycle was measured by flow cytometry. The ability of invasion and speed of cell migration were evaluated by transwell chamber invasion and cell scratch assay. The influence of HMGB1 silencing on the proliferation of LoVo cells in vivo was observed in LoVo tumor-bearing nude mice.</p><p><b>RESULTS</b>Lentivirus-mediated siRNA was successfully transfected into colorectal cancer cell line LoVo. The expression of HMGB1 mRNA and protein in the HMGB1-siRNA group were 0.24±0.04 and 0.21±0.03, respectively. Compared with the HMGB1-siRNA-Neg group (0.82±0.13, 1.15±0.18) and control group (0.93±0.15, 1.21±0.20), the difference was significant (P<0.05). MTT assay showed that the cell proliferation in the HMGB1-siRNA group was significantly inhibited when compared with that in the HMGB1-siRNA-Neg group and control group (P<0.05). Flow cytometry showed that the proliferation index (PI) of HMGB1-siRNA group was 38.27±1.32, significantly lower than 54.66±1.74 in the HMGB1-siRNA-Neg group and 57.43±1.29 in the control group (P<0.05). The transwell assay showed that the number of penetrated cells in the HMGB1-siRNA group was 14.0±3.5, significantly lower than 51.0±6.7 in the HMGB1-siRNA-Neg group and 68.0±5.3 in the control group (P<0.05). Similarly, the scrape wound recovered significantly slower in the HMGB1-siRNA group (83.61±23.21) µm than that in the other two groups (202.86±46.46) µm and (214.58±57.38) µm(P<0.05). The nude mouse xenograft tumor experiment showed that the final tumor volume was (521±34) mm3 in the HMGB1-siRNA group, significantly smaller than that in the HMGB1-siRNA-Neg group of (763±46) mm3 and control group of (802±51) mm3 (P<0.05).</p><p><b>CONCLUSIONS</b>Lentivirus-mediated HMGBl-siRNA can effectively inhibit the HMGB1 expression in colorectal cancer LoVo cells both in vitro and in vivo. HMGB1 gene silencing can slow the growth of colorectal cancer cells, extend the cell proliferation cycle, decrease their invasion and migration, and significantly inhibit the growth of xenograft tumor in nude mice.</p>

ABSTRACT

<p><b>BACKGROUND</b>Several studies found that vitamin D3 might alter glucose metabolism, protect kidney from injury and even proposed the mechanisms. But results from previous studies have been conflicting. The aim of this study was to evaluate the efficacy and safety of vitamin D3 in patients with diabetic nephropathy. The underlying mechanism of vitamin D3 decreasing proteinuria is also discussed.</p><p><b>METHODS</b>We conducted a search of English and Chinese articles using database of Pubmed, Embase, Sinomed, CNKI, Wanfang and clinical trial register centers, for randomized controlled trials of vitamin D3 in diabetic nephropathy patients. Two reviewers performed independently. Meta-analysis was used when studies were homogeneous enough.</p><p><b>RESULTS</b>Twenty studies, including 1 497 patients with diabetic nephropathy, were involved in this systemic review. Vitamin D3-treated patients with diabetic nephropathy had a statistically significant reduction in 24-hour proteinuria (weighted mean difference -0.44, 95% CI -0.54 to -0.34, Z = 8.80, P < 0.000 01) and urine albumin/creatine ratio (standardized mean difference -0.29, 95% CI -0.48 to -0.10, Z = 2.96, P = 0.003). But vitamin D3 supplementation did not significantly reduce blood pressure and hemoglobin A1c compared with control group. The potential mechanisms about the renal protection of vitamin D3, including the inhibition of rennin-angiotensin system, the protection of kidney from inflammation, fibrosis and the structure change of kidney are discussed. In addition, vitamin D3 did not significantly increase the incidence of adverse effects, including total adverse effects, gastrointestinal adverse effects and fluctuation of blood pressure.</p><p><b>CONCLUSIONS</b>Vitamin D3 can ameliorate proteinuria and protect kidney from injury in patients with diabetic nephropathy. This renoprotective effect is independent of blood pressure and glucose reduction. And it does not increase any adverse effects than control, even in combination therapy with angiotensin converting enzyme inhibitors/angiotensin receptor blockers. But due to the limited randomized controlled trials of high quality, more clinical researches should be taken in the future.</p>

Objective To explore the effect of probiotics on patients with severe acute pancreatitis.Methods Randomized controlled trials of probiotics in patients with severe acute pancreatitis were searched in Cochrane Library(2010),Medline(1966 to September 2010),China Academic Literature Full-text Database,Chinese Science and Technology Journal Database and WanFang Database between 1966 and September 2010.Evaluation of literature quality and data extraction were independently completed by two researchers.Data were analyzed with RevMan4.3 software.Results A total of 313 papers had been searched.After excluded duplicated and low-level paper,six articles were included in this study.The result showed that the infection rate(OR=0.88,95%CI[0.56,1.38])and mortality rate(OR=1.44,95%CI[0.78,2.64])of patients with severe acute pancreatitis in intervention group were not lower than control group,however the length of stay in hospital was shorter in intervention group than control group(WMD=-4.69,95% CI[-7.73,-1.65]).There was no significant difference between intervention group and control group in systemic inflammatory response syndrome(OR =1.33,95 % CI[0.63,2.83]),multiple organ failure (OR=1.50,95 % CI[0.89,2.52])and transfering to surgery department for further treatment(OR=0.92,95%CI[0.56,1.51]).Conclusion So far the studies indicated that probiotics could not lower the infection rate and mortality rate in patients with severe acute pancreatitis.Large sample and highquality randomized controlled trials are needed for further evaluation.

ABSTRACT

Objective To compare the differences of cardiac function and interstitial remodeling between diastolic heart failure(DHF) and systolic heart failure(SHF) rabbit models. Methods To establish DHF model with abdo-mial aorta constriction and SHF model with abdomial aorta constriction plus aortic insufficiency. The cardiac func-tion was examined by UCG parameters and homodynamic parameters. The collagen content was measured through hydroxyproline colorimetric assay and shown as collagen area(CA), collagen volume fraction(CVF) and area ratio of Ⅰ to Ⅲ type collagen with PSR. Results Compared with control group, there were significantly increased thick-ness and stiffness of myocardium, impaired diastolic function but normal ejection fraction (EF), and significantly increased collagen content, CA, CVF and area ratio of Ⅰ to Ⅲ type collagen in DHF group; heart chamber was sig-nificantly enlarged, systolic function decreased, and collagen content, CA, CVF significantly increased, but ratio of Ⅰ to Ⅲ type collagen decreased in SHF group(P <0.05 or P <0.01). Conclusion DHF and SHF rabbit mod-els were established successfully, which can simulate clinical profiles and provide technical support to future re-search.

ABSTRACT

0.05). There were 7 cased in the polypropylene mesh group had abdominal discomfort due to stiffness, which higher than that of the expanded polytetrafluroethylene patch and control groups (P 0.05). CONCLUSION: Both prosthetic patches are safe and effective when used in the repair of inguinal hernia in aged patients with low recurrence rate, especially, the expanded polytetrafluroethylene patch, which is more comfortable than polypropylene mesh.

ABSTRACT

Objective To investigate the heterogeneity of chemosensitivity in colorectal cancer using an ATP-tumor chemosensitivity assay (ATP-TCA) and the feasibility of individual chemotherapy.Methods An ATP-TCA were used to determine the effect of 16 single or combined cytotoxic drugs in surgical specimens from 50 patients with colorectal cancer.Results There were considerable differences in chemosensitivity between individuals.The most active single drugs in the assay was identified as Navelbine, Hydroxycamptothecin, 5-Fluorouracil and Paclitaxel; 34.1%, 31.6%, 27.6% and 24.3% of specimens showed sensitivity to them, respectively.5-Fluorouracil+Mitomycin+Aytarabine was found to be the most effective combination, for 100% (11/11)specimens were sensitive to this regimen.5-Fluorouracil+Cisplatin+Adriamycin and Gemcitabine+Cisplatin were moderately active regimens.Conclusions There was the heterogeneity of the in vitro chemosensitivity in colorectal cancer.The use of the ATP-TCA provides a method of selecting appropriate anti-cancer drugs in colorectal cancer.
