Objective To compare the difference between a vertical line (AA) drawn to the line connecting the inner edge of the patellar tendon with the mid-point of the ending point in the posterior cruciate ligament, tibial posterior condylar line (PC), tibial plateau anterior line (AC), the maximal mediolateral distance (MMLD) and a vertical line (BB) drawn to aligning the mid-point of ending point in the posterior cruciate ligament with the medial 1 / 3 of the patellar tendon relative to the surigical transepicondylar axis (STEA) by MRI, and to explore a reliable reference to determine tibial component rotation in total knee arthroplasty , and whether it will change in knees with varus deformity. Methods Thirty healthy volunteers (Group1) and thirty osteoarthritis patients (Group2) were enrolled in this study. The angles were measured among the five tibial rotation axes and STEA after MRI. Results The angles were (-1.48 ± 2.38)°, (6.16 ± 4.53)°, (6.45 ± 5.24)° ,(5.08 ± 4.99)° and (3.24 ± 2.68)° respectively in group 1 and (-1.88 ± 2.21)°, (-3.13 ± 4.66)°, (11.13 ± 5.72)°, (4.11 ± 4.15)° and (5.12 ± 4.87)° respectively in group 2. The angle between AA and STEA was not affected by varus deformity (P > 0.05), but the others were (P < 0.05). Conclusion The angle between AA and STEA is the smallest which is used to determine tibial component rotation in knees with varus deformity is the most reliable one.

Objective:To explore the application feasibility of modified sentinel lymph node biopsy (SLNB) for acral malignant melanoma.Methods:The data of 60 patients with acral malignant melanoma in the Affiliated Tumor Hospital of Xinjiang Medical University from January 2017 to January 2020 were retrospectively analyzed. According to the sentinel lymph node (SLN) detection method, they were divided into observation group (30 cases) and control group (30 cases). The observation group used contrast-enhanced ultrasound combined with subcutaneous injection of methylene blue around the wrist or ankle joint to detect SLN; the control group used peritumoral injection of methylene blue to detect SLN. The patients were regularly followed up to evaluate the postoperative effect. The detection number, detection rate, sensitivity, false negative rate and the size of SLN were compared between the two groups.Results:In the observation group, the detection rate of SLN was 100.0% (30/30), the sensitivity was 87.5% (7/8), and the false negative rate was 3.3% (1/30); in the control group, the detection rate of SLN was 83.3% (25/30), the sensitivity was 62.5% (5/8), and the false negative rate was 12.0% (3/25); the differences were statistically significant (all P < 0.05). The number of SLN detected in the observation group (3.5±1.2) was significantly more than that in the control group (2.0±1.1), and the difference was statistically significant ( t = 7.121, P < 0.05). The minimum long-axis diameter of SLN detected in the observation group was (5.4±2.2) mm (range, 1.5-12.3 mm), and that in the control group was (11.8±5.4) mm (range, 10.0-16.8 mm), the difference between the two groups was statistically significant ( t = 6.353, P < 0.05). Conclusion:The modified SLNB for acral malignant melanoma has a higher application value in the detection of acral SLN than the peritumoral injection method, and a higher accuracy rate can be obtained.

Objective To investigate the specific humoral immune response and cellular immune response induced by DNA vaccine with Neisseria gonorrhoeae porin B (PorB) fused with B subunit of Escherichia coli heat-labile enterotoxin B (LTB) in mice. Methods Target genes of porB, ltB and ltB-porB were amplified by polymerase chain reaction (PCR) and cloned into eukaryotic vector pcDNA3.1(-). The recombinants were identified by PCR, enzyme digestion and DNA sequencing.The vectors were transfected into Hela cells, and expressed proteins were checked by cytoimmunofluorescence. Female BALB/c mice were intranasally immunized with recombination vectors. The humoral immune response and cellular immune response were detected by enzyme linked immunosorbent assay (ELISA) and methyl thiazolyl tetrazolium (MTT) colorimetric assay. The expressions of recombination vectors in intranasal mucosal tissues of the immunized mice were detected by immunohistochemistry. The means between groups were compared by analysis of variance. Results All the three recombinants were expressed in Hela cells and intranasal mucosal tissues. The PorB specific IgG in serum and sIgA in vaginal secretions in DNA vaccine immunized mice were significantly higher than those in controls (P＜0.01 ; P＜0.05). Moreover, the sIgA level in pcDNA3.1 (-)/ltB-porB group was higher than that in peDNA3, 1(-)/porB group (P＝0. 002). The levels of interferon-gamma (IFN-γ) and interleukin-4 (IL-4) in the supernatants and stimulation index (SI) of spleen lymphocyte culture in pcDNA3, 1(-)/porB group were (170.04±23.89) pg/mL, (114.68±14.27) pg/mL and 1. 68±0.19, respectively; and those in pcDNA3, 1(-)/ltB-porB group were (161.42±27.50) pg/mL, (124.16±19.04) pg/mL and 1.73±0.28, respectively; which were both higher than those in pcDNA3.1(-)/ phosphate buffered saliae (PBS) group (P＜0. 01; P＜0.05) and pcDNA3.1 (-)/ltB group (all P＜0.05), while there was no significant difference between pcDNA3.1 (-)/ltB-porB group and pcDNA3. 1 (-)/porB group (0. 998, 0. 696, 0. 994; all P＞0.05). Conclusions The constructed DNA vaccines are all successfully expressed in Hela cells and murine intranasal mucosal tissues. The mucosal immunization of the vaccines [pcDNA3. 1 (- )/porB and pcDNA3.1 ( -)/ltBporB] could induce humoral immune response and cellular immune response, especially mucosal immune response. It is confirmed that mucosal adjuvant LTB could promote PorB to induce higher level of mucosal immune response in mice.

Objective:To investigate the clinical value of ankle-brachial index (ABI) in evaluating vascular cognitive dysfunction (VCI) in the elderly.Methods:According to the mini mental state examination (MMSE) and Montreal cognitive assessment (MoCA), 200 elderly inpatients from May 2016 to February 2018 in our hospital were selected. MoCA scale was used to evaluate the cognitive function of the patients. The patients were divided into cognitive dysfunction group ( n=110) and cognitive normal group ( n=90). The clinical data of the two groups were analyzed and compared. The correlation between ABI and MMSE, MOCA and clinical indicators was observed. The receiver operating characteristic (ROC) curve of ABI value to the predictive value of VCI in the elderly was drawn. Results:⑴ There was no significant difference between the two groups in terms of gender, the first fasting blood glucose value in hospital and the situation of diabetes, hypertension and hyperlipidemia ( P>0.05); there was significant difference in age, low-density lipoprotein cholesterol (LDL-C) level, history of small cerebral vessels and ABI between the two groups ( P<0.05). ⑵ Logistic regression analysis showed that ABI was the related factor of VCI in the elderly ( P<0.01). ⑶ Pearson correlation analysis showed that MMSE score was positively correlated with ABI ( r=0.887, P<0.01), MOCA score was positively correlated with ABI ( r=0.843, P<0.01). ⑷ The area under ROC curve of ABI prediction value for VCI in the elderly was (0.965±0.01) [95% CI (0.945, 0.985), P<0.01]. When ABI ≤0.9, the sensitivity and specificity were 88.2%, 91.1% respectively; the accuracy and the yordan index were 89.5% and 0.793. Conclusions:⑴ ABI is an influencing factor of VCI in the elderly and is positively correlated with the severity of cognitive impairment in patients. ⑵ ABI has a high predictive value for VCI of the elderly, and ABI≤0.9 can be used as an early warning factor for VCI of the elderly.

OBJECTIVE: To explore the correlation between endothelial microparticles(EMPs) and subacute 1,2-dichloroethane(1,2-DCE) toxic encephalopathy. METHODS: A total of 24 patients with subacute 1,2-DCE toxic encephalopathy were selected as the case group, and 24 healthy individuals were selected as the control group using a convenient sampling method. Blood plasma was collected from the fasting venous blood of patients in these two groups, and the level of EMPs in the plasma was detected by flow cytometry. RESULTS: The levels of plasma EMPs of patients in the control group and the case group were(692.0±174.4) ×10~3/L and(839.8±155.8) ×10~3/L respectively. The levels of plasma EMPs in patients with mild, moderate and severe case subgroups were(691.6±101.9) ×10~3/L,(900.6±46.6) ×10~3/L and(1 026.8±69.8)×10~3/L respectively. The EMPs level of patients in the case group was higher than that of the control group(P<0.01). The level of EMPs in the moderate and severe case subgroups was higher than that of the control group and mild case subgroup(P<0.01). CONCLUSION: Endothelial injury was found in patients with subacute 1,2-DCE toxic encephalopathy and endothelial injury is related to the severity of poisoning.
