RESUMEN
Avulsion fracture of the anterior superior iliac crest (ASIC) following autogenous bone grafting for anterior lumbar fusion (ALF) is an extremely rare complication. We describe a very rare case of avulsion fracture of the ASIC following autograft for ALF in a revision surgery for treating lumbar tuberculosis. A 68-year-old woman with lumbar tuberculosis underwent posterior debridement and posterior iliac crest bone graft fusion; however, her lumbar tuberculosis recurred 9 months after surgery. She then underwent a lumbar revision surgery, including removal of the posterior instrumentation and debridement, followed by anterior L2 corpectomy, debridement, anterior left iliac crest bone graft fusion, and internal fixation. When walking for the first time on postoperative day 3, she experienced a sharp, sudden-onset pain in the anterior iliac crest harvest area. X-ray revealed an avulsion fracture of the ASIC. Considering her failure to respond to conservative treatment for one week and large displacement of the fracture ends, an open reduction and internal fixation surgery was scheduled. Her pain symptoms were significantly relieved after the operation. Although rare, fracture of the ASIC following autograft for ALF should not be ignored. Fracture of the ASIC is usually treated conservatively. Additional surgical treatment is required only when intractable pain fails to respond to conservative treatment or when there is a large displacement of fracture ends that are not expected to heal spontaneously.
RESUMEN
BACKGROUND: The efficiency of the target versus sub-target dose of renin-angiotensin system inhibitors (RASIs) in elderly patients with heart failure (HF) with reduced ejection fraction (HErEF) remains unclear. METHODS: PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched from database inception through March 2022 for randomized controlled trials (RCTs) and observational studies considering the effect of the target versus sub-target dose of RASIs on survival in elderly patients (≥ 60 years) with HErEF. The primary outcome was all-cause mortality. The secondary outcomes were cardiac mortality, HF hospitalization, and the composite endpoint of mortality or HF hospitalization. A meta-analysis was conducted to generate combined hazard ratio (HR) and 95% CI. RESULTS: Seven studies (two RCTs and five observational studies) enrolling 16,634 patients were included. A pooled analysis suggested that the target versus sub-target dose of RASIs led to lower rates of all-cause mortality (HR = 0.92, 95% CI: 0.87-0.98, I2 = 21%) and cardiac mortality (HR = 0.93, 95% CI: 0.85-1.00, I2 = 15%) but not reduced rates of HF hospitalization (HR = 0.94, 95% CI: 0.88-1.01, I2 = 0) and the composite endpoint (HR = 1.03, 95% CI: 0.91-1.15, I2 = 51%). However, the target dose of RASIs was associated with a similar primary outcome (HR = 0.85, 95% CI: 0.64-1.14, I2 = 0) in a subgroup of very elderly patients > 75 years of age. CONCLUSIONS: Our analysis suggests that the target dose of RASIs has a better survival benefit in elderly patients with HFrEF compared to the sub-target dose of RASIs. However, the sub-target dose of RASIs is associated with a similar mortality rate in very elderly patients > 75 years of age. Future high-quality and adequately powered RCTs are warranted.
RESUMEN
RATIONALE: Plasmacytoma is a rare plasma cell dyscrasia that grows within the axial skeleton or soft tissue structures as solitary or multiple masses. The primary types are solitary plasmacytoma, including solitary bone plasmacytoma (SBP) and solitary extramedullary plasmacytoma, and multiple solitary plasmacytomas. SBP is characterized by localized proliferation of monoclonal plasma cells and is rare. However, SBP with chronic osteomyelitis is even rarer. PATIENT CONCERNS: A 47-year-old man previously diagnosed with chronic osteomyelitis presented with repeated discharge and ulceration in the front of his right tibia. DIAGNOSIS, INTERVENTIONS AND OUTCOMES: Lower extremity magnetic resonance imaging (MRI) and computed tomography (CT) examinations showed dead bone formation and surrounding inflammatory edema. Thus, the patient underwent dead bone excision and fenestration of the bone marrow cavity. The histopathologic examination results indicated plasmacytoma. Therefore, we administered radiotherapy with satisfactory results. LESSONS: Physicians should pay close attention to chronic osteomyelitis because it may be accompanied by plasmacytoma. Postoperative pathological and immunohistochemical examinations are crucial, and surgical resection of the lesion and local radiotherapy are effective treatment methods.

BACKGROUND: Cavernous transformation of the portal vein (CTPV) due to portal vein obstruction is a rare vascular anomaly defined as the formation of multiple collateral vessels in the hepatic hilum. This study aimed to investigate the imaging features of intrahepatic portal vein in adult patients with CTPV and establish the relationship between the manifestations of intrahepatic portal vein and the progression of CTPV. METHODS: We retrospectively analyzed 14 CTPV patients in Beijing Tsinghua Changgung Hospital. All patients underwent both direct portal venography (DPV) and computed tomography angiography (CTA) to reveal the manifestations of the portal venous system. The vessels measured included the left portal vein (LPV), right portal vein (RPV), main portal vein (MPV) and the portal vein bifurcation (PVB). RESULTS: Nine males and 5 females, with a median age of 40.5 years, were included in the study. No significant difference was found in the diameters of the LPV or RPV measured by DPV and CTA. The visualization in terms of LPV, RPV and PVB measured by DPV was higher than that by CTA. There was a significant association between LPV/RPV and PVB/MPV in term of visibility revealed with DPV (P = 0.01), while this association was not observed with CTA. According to the imaging features of the portal vein measured by DPV, CTPV was classified into three categories to facilitate the diagnosis and treatment. CONCLUSIONS: DPV was more accurate than CTA for revealing the course of the intrahepatic portal vein in patients with CTPV. The classification of CTPV, that originated from the imaging features of the portal vein revealed by DPV, may provide a new perspective for the diagnosis and treatment of CTPV.
RESUMEN
OBJECTIVE: To study the epidemiological correlation and drug resistance of external factors of infection caused by open injury of limbs to pathogens. METHODS: This experiment is a retrospective study. We took the geographical location and climate of Nanchang, Jiangxi Province, China as the background, analyzed 2017 strains of pathogens from 1589 patients with limb trauma infection in a University Affiliated Hospital from 2012 to 2017. Patients were divided into three groups according to the type of incision: I, In-hospital infection of clean limb incision, II, In-hospital infection with open injury, III, Community infection with open injury of the limb. Groups II and Groups III were divided into six subgroups according to the causes of trauma, including: accidents from non-motor vehicles, machinery, cutting/piercing, pedestrian injuries, struck by/against, pedal cycles, and other injuries. We found eight common pathogens of orthopedic infection, which were mainly divided into Gram-positive bacteria (G+, mainly including Staphylococcus) and Gram-negative bacteria (G-, mainly Enterobacteriaceae). The relationship between main pathogens and damage mechanism, apparent temperature and relative humidity was discussed in this study. SPSS v22.0 was used for statistical analysis of the data. Friedman's two-way ANOVA was used to analyze the difference between the injury mechanism and incidence of pathogenic bacteria. Linear regression was used to determine the trend between the incidence of major pathogens and seasonal temperature and humidity. The level of significance was set as P < 0.05. RESULTS: There was no significant difference in the distribution of pathogens between Groups II and Groups III (P>0.05). The drug resistance of Groups III was significantly higher than that of Groups II and Groups I. G+ bacteria were resistant to cephalosporin, ceftriaxone and other cephalosporins and erythromycin and other macrolides. They were sensitive to vancomycin and linezolid. G- were resistant to the first- and the second-generation cephalosporins, including cefotetan and cefazolin, and ampicillin and other penicillins, while they were sensitive to third-generation cephalosporins, such as ceftazidime, as well as to levofloxacin and other quinolones, meropenem, and other beta-lactamases. The correlation between the injury mechanism and infection of pathogenic bacteria was not significant. The monthly average apparent temperature and relative humidity were correlated with the infection rate of pathogenic bacteria. CONCLUSION: In open injury of extremities, apparent temperature and relative humidity is an important risk factor for infection by pathogenic bacteria and the drug resistance of pathogenic bacteria in out-of-hospital infection was lower than that of hospital infection.

AIM: To compare the short-term impacts of femtosecond lenticule extraction (FLEx) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) on ocular surface measures and tear inflammatory mediators. METHODS: This prospective comparative nonrandomized clinical study comprised 75 eyes (75 patients). Totally 20 male and 15 female patients (age 21.62±3.25y) with 35 eyes underwent FLEx, and 26 male and 14 female patients (age 20.18±3.59y) with 40 eyes underwent FS-LASIK. Central corneal sensitivity, noninvasive tear breakup time, corneal fluorescein staining, Schirmer I test, tear meniscus height, and ocular surface disease index were evaluated in all patients. Tear concentrations of nerve growth factor (NGF), interleukin-1α (IL-1α), transforming growth factor-ß1 (TGF-ß1), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), and matrix metalloproteinase-9 (MMP-9) were assessed by multiplex antibody microarray. All measurements were performed preoperatively, and 1d, 1wk, and 1mo postoperatively. RESULTS: Patients who underwent FLEx exhibited a more moderate reduction in central corneal sensation and less corneal fluorescein staining than those in the FS-LASIK group 1wk after the procedure (P<0.01). NGF was significantly higher 1d and 1wk after surgery in the FS-LASIK group than in the FLEx group (P<0.01). By contrast, compared to those in the FLEx group, higher postoperative values and slower recovery of tear TGF-ß1, IL-1α, and TNF-α concentrations were observed in the FS-LASIK group (P<0.01). Tear concentrations of NGF, TGF-ß1, TNF-α, and IL-1α were correlated with ocular surface changes after FLEx or FS-LASIK surgery. CONCLUSION: There is less early ocular surface disruption and a reduced inflammatory response after FLEx than after FS-LASIK. NGF, TGF-ß1, TNF-α, and IL-1α may contribute to the process of ocular surface recovery.
RESUMEN
A pandemic of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection broke out all over the world; however, epidemiological data and viral shedding in pediatric patients are limited. We conducted a retrospective, multicenter study, and followed-up with all children from the families with SARS-CoV-2 infected members in Zhejiang Province, China. All infections were confirmed by testing the SARS-CoV-2 RNA with real-time reverse transcription PCR method, and epidemiological data between children and adults in the same families were compared. Effect of antiviral therapy was evaluated observationally and fecal-viral excretion times among groups with different antiviral regiments were compared with Kaplan-Meier plot. By 29 February 2020, 1298 cases from 883 families were confirmed with SARS-CoV-2 infection and 314 of which were families with children. Incidence of infection in child close contacts was significantly lower than that in adult contacts (13.2% vs 21.2%). The mean age of 43 pediatric cases was 8.2 years and mean incubation period was 9.1 days. Forty (93.0%) were family clustering. Thirty-three children had coronavirus disease 2019 (20 pneumonia) with mild symptoms and 10 were asymptomatic. Fecal SARS-CoV-2 RNA detection was positive in 91.4% (32/35) cases and some children had viral excretion time over 70 days. Viral clearance time was not different among the groups treated with different antiviral regiments. No subsequent infection was observed in family contacts of fecal-viral-excreting children. Children have lower susceptibility of SARS-CoV-2 infection, longer incubation, and fecal-viral excretion time. Positive results of fecal SARS-CoV-2 RNA detection were not used as indication for hospitalization or quarantine.

Background: Infection, including mixed infection, is not uncommon in orthopedic surgical incision. This study aimed to investigate the epidemiology and drug resistance of mixed infections after orthopedic surgical procedures. Methods: We retrospectively analyzed 533 orthopedic surgical site infections (SSIs) in a university hospital from 2012 to 2017. Eighty-six patients (218 strains) with bacterial culture results showing more than one strain were screened to explore their epidemiology and drug resistance. Results: Of 218 bacterial strains, 2-7 bacterial infections were noted in each wound. Most infections were caused by two kinds of bacteria (65.1%). The number of infections decreased with increased number of strains. The combinations of pathogenic micro-organisms were all gram-negative, 55.81%; gram-positive and gram-negative, 30.23%; all gram-positive, 12.79%; and gram-positive and fungi, 1.16%. Their resistance is consistent with the bacterial resistance of 447 cases of single bacterial SSI during the same period. Hospitalization duration was longer (9.8-20.6 d). Conclusion: Our study shows no significant changes in epidemiology and drug resistance caused by mixed infections in the orthopedic surgical site because of coordination and competition among micro-organisms. These bacteria are difficult to control, leading to extended hospitalization. Antibiotic agents should be chosen strictly according to drug sensitivity, and ineffective antibiotic agents must be avoided.

The aim of this study was to explore the effect of emodin on lipid accumulation and inflammation in hepatocytes. The cell morphology was observed by microscopy. LDH release was detected by the kit. Levels of intracellular lipid droplets were observed by oil red O staining. The contents of TC and TG in cells were detected by the kit. Western blot was used to determine protein expressions of FASN,SREBF2,APOB,IL-6 and p-NF-κB in hepatocytes. The results showed that the levels of L02 cell LDH were significantly increased after being treated with emodin,and the cells showed shrinkage,volume reduction,decrease in quantity with the increase of dose. Red lipid droplets were observed in L02 hepatocytes. Intracellular TC and TG contents of L02 cell increased in a concentrationdependent manner,with significant differences between medium and high-dose groups( P < 0. 05). Protein expressions of FASN,SREBF2,IL-6 and p-NF-κB were significantly higher than those of the control group,and the expression level of APOB was significantly lower than that of the control group( P<0. 05). In conclusion,emodin could induce lipid accumulation and inflammatory damage in hepatocytes in a dose-dependent manner,which in turn could damage liver cells. This process was related to the up-regulation of FASN,SREBF2,IL-6,p-NF-κB,as well as the down-regulation of the protein expression of APOB.

Tumor samples of pancreatic ductal adenocarcinoma patients, who underwent resection surgery, were implanted into NOD/SCID mice to construct pancreatic cancer patient-derived xenograft (PDX) models and explore the biological changes in the different generations of PDXs. Ten PDXs were successfully generated, and the tumor formation rate of F1 PDXs was found to be 38.46%, which was lower than F2 (77.78%) and F3 (71.43%) PDXs. In addition, latent periods of tumorigenesis of F2 and F3 PDXs were significantly shorter, compared to that in F1 PDXs (P<0.05). Comparison of H&E staining of tumor tissue from primary pancreatic cancer and PDXs showed that all three generations of PDXs had similar histopathology to primary pancreatic cancer, indicating that PDXs may well reproduce the histological patterns of primary human cancer. Besides, Ki67 expression was increased in all three generations of PDXs compared to primary tumors of patients, and additionally, EpCAM expression was increased in F3 PDXs. These results were corroborated by the real-time qPCR and western blot results. Therefore, we concluded that PDXs are able to preserve the differentiation degree, morphological characteristics, and structural features of tumor cells. Furthermore, the latent periods of tumorigenesis are shortened after the first generation, which may be attributed to an increase in expression levels of tumor promoters such as Ki67 and EpCAM. PDX models may become an efficient tool for pancreatic cancer research.
RESUMEN
Objective To investigate the relationship between body mass index(BMI)and risk levels of thyroid nodules in a multi-center healthy population. Methods A total of 6070 subjects were enrolled from five medical physical examination centers in China from January 2015 to December 2017. All the participants'general information and parameters were recorded. Thyroid nodules were detected by color Doppler ultrasonography. All ultrasound doctors received uniform training before study. Results Among all the subjects,5773(95.1%;with 4274 nodules identified in 2833 subjects)were from northern China and 297(4.9%,with 183 nodules identified in 158 subjects)from central China(χ2=1.923,P=0.092). The nodules were single in 1479 of 2991 subjects(49.4%)and multiple in 1512 subjects(50.6%). Nodules larger than 1 cm accounted for 13.3% and nodules smaller than 1 cm accounted for 86.7%. Compared with the non-thyroid nodule group,the thyroid nodule group had significantly more women(χ2=156.36,P=0.000),older age(t=-18.768,P=0.000),and higher fasting blood glucose(FBG) level(t=-3.808,P=0.000). Among all the nodules,the prevalence rates of benign,very-low-risk,low-risk,moderate risk,and high risk were 4.5%,6.6%,85.0%,0.1%,and 3.7%,respectively,according to the ATA guidelines. Notably,there were 4291 nodules at moderate or lower risks and 166 nodules at high risk. Compared with the former,patients with high-risk nodules had significantly lower BMI(χ2=25.161,P=0.000)and high FBG(t=3.357,P=0.000). Multivariate non-conditional Logistic regression showed low BMI(OR=2.900,95%CI:1.461-5.783,P=0.002)and high FBG level(OR=0.803,95%CI:0.675-0.955,P=0.013)were independent risk factors for high-risk nodules. Compared with subjects with normal weight or obese populations,subjects with low BMI had significantly higher detection rate of high-risk nodules(χ2=25.16,P=0.000). In ≥55 year-old group,significantly more high-risk nodules were detected in low BMI group(χ2=44.868,P=0.000). Conclusion Low weight is associated with high-risk thyroid nodules among people ≥55 years old.

Objective: The objectives of this study were to examine the clinical profile of critically ill patients with septic acute kidney injury (AKI) and to investigate clinical characteristics associated with the outcome of patients. Methods: Data from 582 critically ill patients were collected and retrospectively reviewed. Patients were divided into two groups: without AKI development and with AKI development. Baseline characteristics, laboratory, and other clinical data were compared between these two groups, and correlations between the characteristics and AKI development were examined. Patients with AKI development were further divided into two groups according to the survival outcome, and variables associated with the outcome were determined. Results: AKI was developed in 54.12% (n = 315) of patients, and these patients had blood pressure, SOFA score, APACHE II score, GCS, and various blood chemistry and hematology characteristics significantly different from the patients without AKI. Demographic characteristics (e.g. age and weight) were comparable between the two groups of patients. Among the 315 patients with AKI, 136 of them died during the study period. Multivariate logistic regression analysis revealed that the outcome of patients was associated with lung infection, coagulation system dysfunction, staphylococcus aureus infection, and use of various treatments (epinephrine, norepinephrine, and the use of mechanical ventilation) after AKI development. Conclusion: AKI occurred in approximately half of the critically ill patients admitted to ICU. The site and type of infections, as well as the use of vasopressor agents, were associated with the outcome.

Background: Cutaneous lichen amyloidosis (CLA) has been reported in some multiple endocrine neoplasia type 2A (MEN 2A) families affected by specific germline RET mutations C634F/G/R/W/Y or V804M, as a characteristic of the clinical manifestation in 'MEN 2A with CLA', one of four variants of MEN 2A, which was strictly located in the scapular region of the upper back. Patient Findings: This study reports a large south-eastern Chinese pedigree with 17 individuals carrying the MEN 2A-harboring germline C611Y (c.1832G>A) RET mutation by Sanger sequencing. One individual presented MEN 2A-related clinical features, including typical CLA in the interscapular region; another individual exhibited neurological pruritus and scratching in the upper back but lacked CLA skin lesions. Both subjects presented with CLA or pruritic symptoms several years before the onset of medullary thyroid carcinoma (MTC) and/or pheochromocytoma. The remaining 15 RET mutation carriers did not exhibit CLA; of these, one presented with MTC and pheochromocytoma, nine with MTC only, two with elevated serum calcitonin and three younger subjects with normal serum calcitonin levels. This family's clinical data revealed a later diagnosis of MTC (mean age, 45.9 (range: 2373) years), a lower penetrance of pheochromocytoma (2/17, 11.8%) and CLA (1/17, 5.9%). However, no hyperparathyroidism and Hirschsprung disease were reported in this family. Summary and Conclusions: This is the first description of a family with MEN 2A-related CLA due to a germline RET C611Y mutation, which might exhibit a novel and diversified genotypephenotype spectrum in MEN 2A.
RESUMEN
This study retrospectively evaluated the effect of smoking cessation intervention in pregnant women with smoking.A total of 176 pregnant smokers were included in this study. Ninety-five participants received smoking cessation intervention plus physical activity, and were assigned into a treatment group. Eighty-one participants underwent physical activity only, and were assigned into a control group. Primary outcomes included the number of participants quit smoking, daily cigarettes consumption, and quit attempts. The secondary outcomes included infant outcomes. All primary outcomes were measured after 12-week treatment and at delivery. Secondary outcomes were measured at delivery only.After 12-week treatment, participants in the treatment group did not significantly reduce the number of participants quit smoking; decrease daily cigarettes consumption, and quit attempts in pregnant smokers, compared with subjects in the control group. At delivery, the comparison also did not show significant differences in the number of participants quit smoking, decreasing daily cigarettes consumption, and quitting attempts in pregnant smokers, as well as all infant outcomes between 2 groups.The results of this retrospective study did not found that smoking cessation intervention may help to quit smoking for pregnant smokers.

OBJECTIVE: To compare the radiologic and clinical outcomes between oblique lumbar interbody fusion (OLIF) without laminectomy and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF). METHODS: This was a retrospective study. Between April 2012 and January 2017, 25 patients in each of the MI-TLIF and OLIF groups were recruited as matched pairs. Clinical outcomes included visual analogue scale, Oswestry Disability Index, and satisfaction rates. Radiographic outcomes comprised disc height (DH) and fusion status. Intraoperative data and complications were collected. All patients completed the clinical and radiologic outcomes. Outcomes were compared preoperatively and postoperatively. RESULTS: Matched pairs were compared between 2 groups in terms of demographic data and preoperative measurements; less blood loss and shorter operative time were found in OLIF versus MI-TLIF (P < 0.001). The total complication rate was 36% in OLIF and 32% in MI-TLIF (P = 0.77). The outcomes of visual analogue scale and Oswestry Disability Index were significantly improved in both groups, and there was no significant difference between 2 groups. Satisfaction rates of the both groups were more than 90%. OLIF was superior to MI-TLIF with respect its capability to restore DH (P < 0.001). Earlier time of fusion was observed in OLIF (80%) compared with MI-TLIF (52%) at 6 months (P = 0.04). CONCLUSIONS: OLIF may achieve equivalent clinical and radiologic outcomes compared with MI-TLIF when the stenosis is minimal because the decompression performed is indirect. Furthermore, the OLIF shows less blood loss and shorter operative time, better restoration of DH, and earlier time to fusion than the MI-TLIF.

OBJECTIVES: Hypoalbuminaemia has been proved to be a biomarker of poor prognosis in many diseases. The objective of this study was to investigate the significance of hypoalbuminaemia in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS: Data of 117 AAV patients were analysed retrospectively. The relationship between hypoalbuminaemia and disease severity were studied. The influence of albumin on the pathogenetic role of ANCA was investigated in vitro. RESULTS: Among all patients, 52 had light hypoalbuminaemia (30g/L<=albumin<35g/L) and 40 had nephrotic hypoalbuminaemia (albumin <30g/L). Patients with hypoalbuminaemia had higher inflammation levels and more severe kidney injury than patients without hypoalbuminaemia, but no significant difference of the urinary protein levels were found between patients with nephrotic and light hypoalbuminaemia. Multivariate analysis showed serum albumin correlated with age (r=-0.566, p=0.018), C-reactive protein (r=-0.521, p=0.032) and haemoglobin (r=0.512, p=0.036). Patients with nephrotic hypoalbuminaemia had higher incidence of infection, end stage renal disease and all cause mortality during treatment than patients with light hypoalbuminaemia or normal serum albumin. In vitro study indicated albumin could inhibit the binding between ANCA and neutrophils in a concentration dependent manner. Albumin also inhibited the ANCA-induced respiratory burst and neutrophil extracellular traps formation. CONCLUSIONS: Serum albumin have an inhibitory effect on the binding between ANCA and its antigen. The incidence of hypoalbuminaemia in AAV with kidney involvement is high but is not caused by heavy proteinuria. Hypoalbuminaemia is correlated with the high inflammation level and poor prognosis of AAV. Therapy targeting hypoalbuminaemia might benefit patients with AAV.

OBJECTIVE: We investigated the feasibility and efficacy of cognitive training for older adults in rural settings and with low education levels, who have mild cognitive impairment (MCI). METHODS: Forty-five older adults (ages >65 years) with MCI were assigned to treatment or control groups, at a 2:1 ratio. Cognitive training occurred in the treatment group for 2 months. The cognitive abilities of the participants were assessed at pre-training, metaphase, and post-training time points, using the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Loewenstein Occupational Therapy Cognitive Assessment (LOTCA), and Hamilton Depression Scale (HAM-D). RESULTS: Following training, cognitive abilities improved in the treatment group, based on the total scores of all 4 measures, as well as specifically on the MoCA and LOTCA. There were differences in the main effects of group and time point on some subscales, but these differences had little, if any, effect on the overall analyses. CONCLUSION: The present study demonstrated that cognitive training has beneficial effects on attention, language, orientation, visual perception, organization of visual movement, and logical questioning in patients with MCI. Furthermore, the observed effects are long-term changes.

The knee joint is extremely susceptible to injury, which is usually identified by magnetic resonance imaging (MRI). In the present study, MRI was applied to quantitatively detect the association between anterior cruciate ligament (ACL) rupture and anatomic morphologic changes of the intercondylar notch. Forty patients with unilateral ACL rupture who were treated between July, 2013 and October, 2014 were enrolled in the present study. The patients were divided into the observation (affected side) and control (healthy side) groups. MRI measurements were undertaken based on parameters associated with intercondylar notch of double knee joints. The results showed that intercondylar notch width (ICW) in the observation group was significantly smaller than that in the control group, and differences were statistically significant (P<0.05). Differences on the intercondylar notch height and femoral condyle width [epicondylar width (EW)] between the two groups were not statistically significant (P>0.05). Notch width index (NWI) and notch shape index (NSI) in the observation group were significantly less than those in the control group and differences were statistically significant (P<0.05). Differences of Lysholm and Tegner scoring between the two groups were not statistically significant (P>0.05). The differential value of ICW in the observation group was 2.6±1.3 mm and the ACL rupture time of the affected knee was 20.4±1.3 months on average. The correlation was statistically significant (P<0.05). The correlation of Lysholm scoring, Tegner scoring and intercondylar notch stenosis degree on the affected knee was not statistically significant (P>0.05). In conclusion, after ACL rupture, ICW on the affected knee had significant stenosis, NSI and NWI were significantly reduced and the stenosis degree was aggravated with the prolongation of course. By contrast, Lysholm and Tegner scoring of patients with different degrees of stenosis had no correlation.
RESUMEN
Interleukin 8 (IL8) is an important chemokine that elicits host immune response against tuberculosis (TB). However, whether there is an association between IL8 gene polymorphism and TB susceptibility in the Chinese population is unknown. IL8 gene was amplified and sequenced to search for nucleotide polymorphisms among the Chinese population. Four single nucleotide polymorphisms (SNPs) were identified, selected, and analyzed in a cohort of 438 patients with TB and 536 healthy controls. Allelic, genotypic, and haplotypic analysis demonstrated that the distribution of the four IL8 SNPs between patients with TB and healthy controls was not significantly different (P>0.05). The four IL8 SNPs detected in this study were not associated with TB susceptibility in the Chinese population. Secretion of IL8 by peripheral blood cells was greatly stimulated upon exposure to Mycobacterium tuberculosis whole cell extract, but such enhanced secretion was not associated with the IL8 rs4073 alleles.
