ABSTRACT

BACKGROUND@#Total knee arthroplasty (TKA) can reduce severe joint pain and improve functional disability in hemophilia. However, the long-term outcomes have rarely been reported in China. Therefore, this study aimed to evaluate the long-term outcomes and complications of TKA in Chinese patients with hemophilic arthropathy.@*METHODS@#We retrospectively reviewed patients with hemophilia who underwent TKA between 2003 and 2020, with at least 10 years of follow-up. The clinical results, patellar scores, patients' overall satisfaction ratings, and radiological findings were evaluated. Revision surgery for implants during the follow-up period was recorded.@*RESULTS@#Twenty-six patients with 36 TKAs were successfully followed up for an average of 12.4 years. Their Hospital for Special Surgery Knee Score improved from an average of 45.8 to 85.9. The average flexion contracture statistically significantly decreased from 18.1° to 4.2°. The range of motion (ROM) improved from 60.6° to 84.8°. All the patients accepted patelloplasty, and the patients' patellar score improved from 7.8 preoperatively to 24.9 at the last follow-up. There was no statistically significant difference in clinical outcomes between the unilateral and bilateral procedures, except for a better ROM at follow-up in the unilateral group. Mild and enduring anterior knee pain was reported in seven knees (19%). The annual bleeding event was 2.7 times/year at the last follow-up. A total of 25 patients with 35 TKAs were satisfied with the procedure (97%). Revision surgery was performed in seven knees, with 10- and 15-year prosthesis survival rates of 85.8% and 75.7%, respectively.@*CONCLUSIONS@#TKA is an effective procedure for patients with end-stage hemophilic arthropathy, which relieves pain, improves knee functions, decreases flexion contracture, and provides a high rate of satisfaction after more than ten years of follow-up.

ABSTRACT

Objective To evaluate the impact of overall burden of cerebral small vessel disease(CSVD)combined with intracranial large artery atherosclerosis(ICAS)on cognitive function in very old patients.Methods A total of 178 advanced elderly patients admitted to Department of General Medicine of Wuhan Central Hospital between January 2013 and December 2022 were re-cruited in this retrospective study.According to the results of Montreal Cognitive Assessment Scale,they were divided into dementia group(n=83)and non-dementia group(n=95).All pa-tients underwent brain MRI imaging,MRI susceptibility weighted imaging and cerebral angiogra-phy.Based on these imaging findings of MRI,the effect of total burden score of CSVD and athero-sclerosis on cognition were evaluated.The volumes of 14 different gyri in the left and right brain were measured in the patients with CSVD burden score ≤2 and those ≥3.Results There were significantly more patients with numbers of microbleeding foci>10 and lacunar foci ≥5 in the dementia group than the non-dementia group(P<0.01).But,no statistical difference was seen in intracranial and extracranial arterial stenosis between the two groups(P>0.05).The volumes of left and right anterior cingulate gyrus,left and right paracingulate cortex,right hippocampus,left parahippocampal gyrus,right transverse temporal gyrus and left inferior temporal gyrus were no-tably smaller in the CSVD score ≥3 group than the CSVD ≤2 group(1723.444 vs 1867.167,1590.167 vs 1595.670,1481.466 vs 1509.540,1543.831 vs 1585.505,1038.345 vs 1305.831,1220.525 vs 1392.352,P<0.05).Conclusion Cognitive function in the advanced elderly is mainly affected by the burden of CSVD,and atherosclerotic stenosis of large arteries is not the main fac-tor affecting cognitive function.The total burden of CSVD is correlated with atrophy of some gyri.

ABSTRACT

Objective:To compare the diagnostic efficacy of 18F-prostate specific membrane antigen (PSMA)-1007 PET/CT and mpMRI in the diagnosis of pelvic lymph node metastasis of prostate cancer (PCa). Methods:The clinical data of 30 patients who underwent 18F-PSMA-1007 PET/CT and mpMRI examinations in Sichuan Cancer Hospital from November 2018 to April 2021 were analyzed. The average age was (68.4±6.4) years old. The preoperative total PSA was 45.70(16.07, 100.00)ng/ml. Among 30 patients, 14 cases were found lymph node positive by PET/CT and 7 cases were found lymph node positive by mpMRI.Combined with the two preoperative imaging methods and the patient's PSA level, there was 1 patient in stage T 1, 20 patients in stage T 2, 6 patients in stage T 3, and 3 patients in stage T 4. Twenty-nine cases were classified as high risk group and one case was in moderate risk group.All 30 patients underwent laparoscopic radical prostatectomy and enlarged pelvic lymph node dissection (ePLND). According to the postoperative pathological results, the sensitivity, specificity, positive predictive value and negative predictive value of the two imaging techniques for the diagnosis of PCa pelvic lymph node metastasis were calculated, and the consistency of the two imaging techniques for the postoperative pathological results was observed by Kappa test. Results:All the 30 patients were confirmed to be PCa by postoperative pathology, among which 10 patients were positive for pelvic lymph node biopsy. The sensitivity, specificity, positive predictive value and negative predictive value of 18F-PSMA-1007 PET/CT for pelvic lymph node metastasis were 100.0% (10/10), 80.0% (16/20), 71.4%(10/14) and 100.0%(16/16) respectively, and Kappa value was 0.727. The sensitivity and specificity of mpMRI were 70.0% (7/10) and 100.0% (20/20), the positive and negative predictive values were 100.0% (7/7) and 87.0%(20/23)respectively, and the Kappa value was 0.757. The P values of sensitivity, specificity, positive predictive value and negative predictive value between the two imaging methods were 0.18, 0.07, 0.30, <0.01, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of 18F-PSMA-1007 PET/CT in diagnosing the number of pelvic lymph node metastasis were 100%(28/28), 98.2% (373/380), 80.0% (28/35) and 100.0%(373/373), respectively. The sensitivity, specificity, positive predictive value and negative predictive value of mpMRI in diagnosing the number of pelvic lymph node metastasis were 78.6% (22/28), 100.0% (380/380), 100.0% (22/22) and 98.4%(380/386), respectively. The P values of the sensitivity, specificity, positive predictive value and negative predictive value of lymph node detection by the two imaging methods were all <0.01, and the differences were statistically significant. Conclusions:The sensitivity and negative predictive value of 18F-PSMA-1007 PET/CT for the detection of positive lymph node were higher than mpMRI. The specificity and positive predictive value of mpMRI in detecting positive lymph node metastasis were higher than 18F-PSMA-1007 PET/CT examination.

ABSTRACT

Objective:To explore the early warning value of laboratory parameters in patients with severe hemorrhagic fever with renal syndrome (HFRS).Methods:The clinical data of 101 patients with HFRS hospitalized in the Department of Infectious Diseases of the First Hospital of Changsha from December 2013 to December 2020 were collected and analyzed. The differences of clinical routine laboratory parameters between mild and severe HFRS patients were compared and analyzed. The statistical methods including independent sample t test, rank sum test, chi-square test, Spearman rank correlation analysis, logistic regression analysis and receiver operator characteristic curve were used. Results:Among 101 patients with HFRS, 38 cases were in severe group and 63 cases in mild group. White blood cell count, aspartate aminotransferase (AST), prothrombin time (PT), creatine kinase (CK), creatine kinase isoenzyme (CK-MB), serum creatinine, urea nitrogen and D-dimer in severe group were higher than those in mild group, while platelet count and albumin were lower than those in mild group, and the differences were all statistically significant ( t=8.61, Z=-3.76, t=4.19, Z=-2.84, Z=-7.23, t=4.98, t=4.64, t=36.02, Z=-5.49 and t=4.14, respectively; all P<0.050). Severe HFRS was positively correlated with white blood cell count, AST, PT, activated partial thromboplastin time (APTT), CK-MB, serum creatinine, urea nitrogen and D-dimer ( r=0.629, 0.376, 0.549, 0.471, 0.723, 0.500, 0.341 and 0.588, respectively; all P<0.001). White blood cell count, albumin, PT and CK-MB were independent influencing factors for the progression of severe HFRS (odds ratio ( OR)=0.922, 1.374, 0.730 and 0.938, respectively; all P<0.050). The area under curve (AUC) of white blood cell count, albumin, PT and CK-MB for the early warning prediction of severe HFRS were 0.869, 0.739, 0.785 and 0.931, respectively, with the optimal thresholds for prediction of 26.38×10 9/L, 26.05 g/L, 15.95 s and 35.5 U/L, respectively.And the AUC of the combined detection of the above laboratory parameters was 0.950, with the sensitivity of 87.3% and the specificity of 94.7%. Conclusions:White blood cell count, albumin, PT and CK-MB could be used as independent influencing factors for early warning of severe HFRS. Combined detection is more helpful for early warning of severe HFRS than single detection.

ABSTRACT

Objective: To explore the molecular mechanism of cleft palate in mice induced by 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD). Methods: The pregnant mice were randomly divided into TCDD-treated group (n=42) and control group (n=42). TCDD-treated group was given by gavage a single dose of TCDD (64 μg/kg) at 8: 00 AM on gestation day 10 (GD10) and the control group was given by gavage the isopyknic corn oil. At GD13-GD15, the fetal mice palate development was observed by HE staining. The mouse embryonic palatal mesenchymal cell proliferation was detected by 5-bromo-2-deoxyuridine (BrdU) immunofluorescence. The localization and expression of maternally expressed gene3 (MEG3) in mouse embryonic palatal mesenchymal cells was detected by situ hybridization and real-time PCR (RT-PCR). The key protein expressions of transforming growth factor-β (TGF-β)/Smad signaling pathway in mouse embryonic palatal mesenchyme were analyzed by Western blotting. The interaction of MEG3 and TGF-β receptor Ⅰ (TGF-βRⅠ) was examined by RNA binding protein immunoprecipitation (RIP). Results: At GD13 and GD14, compared with the control group, the ratio of BrdU-positive cells in the palatal mesenchyme of TCDD-treated fetuses decreased significantly (GD13, t=6.66, P=0.003; GD14, t=6.56, P=0.003). However, at GD15, the ratio of BrdU-positive cells was significantly increased (t=-5.98, P=0.004). MEG3 was mainly expressed in the nuclei of fetal mouse palatal mesenchymal cells, and the expression of MEG3 in TCDD group was significantly increased at GD13, GD14 and GD15(GD13, t=39.28, P=0.012; GD14, t=18.75, P=0.042; GD15, t=28.36, P=0.045). At GD14, TCDD decreased the levels of p-Smad2 and Smad4 in embryonic palate mesenchymal cells (p-Smad2, t=9.48, P=0.001;Smad4, t=63.10, P=0.001), whereas the expression of Smad7 was significantly increased at GD14 (t=30.77, P<0.001). The results of the RIP experiment showed that the amount of TGF-βRⅠ-bound MEG3 in mouse embryonic palatal mesenchymal cells in the TCDD group (23.940±1.301) was higher than that in the control group (8.537±1.523)(t=24.55, P<0.001). Conclusions: MEG3 is involved in the suppression of mouse embryonic palatal mesenchymal cell proliferation, functioning at least in part via interacting with the TGF-βRⅠ protein and thereby suppressing Smad signaling in the context of TCDD induced cleft palate.

ABSTRACT

Objective: To analyze the feasibility and safety of bridge therapy with active fixed electrodes connected to external permanent pacemakers (AFLEP) for patients with infective endocarditis after lead removal and before permanent pacemaker implantation. Methods: A total of 44 pacemaker-dependent patients, who underwent lead removal due to infective endocarditis in our center from January 2015 to January 2020, were included. According to AFLEP or temporary pacemaker option during the transition period, patients were divided into AFLEP group or temporary pacemaker group. Information including age, sex, comorbidities, indications and types of cardial implantable electionic device (CIED) implantation, lead age, duration of temporary pacemaker or AFLEP use, and perioperative complications were collected through Haitai Medical Record System. The incidence of pacemaker perception, abnormal pacing function, lead perforation, lead dislocation, lead vegetation, cardiac tamponade, pulmonary embolism, death and newly infection of implanted pacemaker were compared between the two groups. Pneumothorax, hematoma and the incidence of deep vein thrombosis were also analyzed. Results: Among the 44 patients, 24 were in the AFLEP group and 20 in the temporary pacemaker group. Age was younger in the AFLEP group than in the temporary pacemaker group (57.5(45.5, 66.0) years vs. 67.0(57.3, 71.8) years, P=0.023). Male, prevalence of hypertension, diabetes mellitus, chronic renal dysfunction and old myocardial infarction were similar between the two groups (all P>0.05). Lead duration was 11.0(8.0,13.0) years in the AFLEP group and 8.5(7.0,13.0) years in the temporary pacemaker group(P=0.292). Lead vegetation diameter was (8.2±2.4)mm in the AFLEP group and (9.1±3.0)mm in the temporary pacemaker group. Lead removal was successful in all patients. The follow-up time in the AFLEP group was 23.0(20.5, 25.5) months, and the temporary pacemaker group was 17.0(14.5, 18.5) months. In the temporary pacemaker group, there were 2 cases (10.0%) of lead dislocation, 2 cases (10.0%) of sensory dysfunction, 2 cases (10.0%) of pacing dysfunction, and 2 cases (10.0%) of death. In the AFLEP group, there were 2 cases of abnormal pacing function, which improved after adjusting the output voltage of the pacemaker, there was no lead dislocation, abnormal perception and death. Femoral vein access was used in 8 patients (40.0%) in the temporary pacemaker group, and 4 patients developed lower extremity deep venous thrombosis. There was no deep venous thrombosis in the AFLEP group. The transition treatment time was significantly longer in the AFLEP group than in the temporary pacemaker group (19.5(16.0, 25.8) days vs. 14.0(12.0, 16.8) days, P=0.001). During the follow-up period, there were no reinfections with newly implanted pacemakers in the AFLEP group, and reinfection occurred in 2 patients (10.0%) in the temporary pacemaker group. Conclusions: Bridge therapy with AFLEP for patients with infective endocarditis after lead removal and before permanent pacemaker implantation is feasible and safe. Compared with temporary pacemaker, AFLEP is safer in the implantation process and more stable with lower lead dislocation rate, less sensory and pacing dysfunction.

ABSTRACT

ObjectiveTo investigate the value of liver stiffness measurement (LSM) and spleen stiffness measurement (SSM) based on FibroTouch (FT) transient elastography combined with serum adenosine deaminase (ADA) in predicting severe esophageal varices (EV) in patients with hepatitis B cirrhosis. MethodsRelated clinical data were collected from 120 patients with hepatitis B cirrhosis who attended Department of Infectious Diseases, Changsha First Hospital, from December 2017 to June 2020. FT was used to measure LSM and SSM, and related examinations were performed, including electronic gastroscopy and serum levels of ADA, hemoglobin, albumin, alanine aminotransferase, and aspartate aminotransferase and platelet count. The serum liver fibrosis markers aspartate aminotransferase-to-platelet ratio index (APRI), aspartate aminotransferase/alanine aminotransferase ratio (AAR), and fibrosis-4 (FIB-4) were calculated. According to the severity of EV under gastroscopy, the subjects were divided into severe EV group with 58 patients and non-severe EV (without EV or with mild-to-moderate EV) group with 62 patients. The t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. The Spearman rank correlation test was used to investigate the correlation of LSM, SSM, and ADA with severe EV. The receiver operating characteristic (ROC) curve was used to analyze the efficacy of LSM, SSM, and ADA in the diagnosis of severe EV, and sensitivity and specificity were calculated. A multivariate binary logistic regression analysis was performed to calculate the area under the ROC curve (AUC) of the combined indicators, and the Z test was used for comparison of AUC. ResultsThere were significant differences in LSM, SSM, and ADA between the two groups (all P<0.05). LSM, SSM, and ADA were positively correlated with severe EV, with a correlation coefficient of 0.686, 0.743, and 0.723, respectively (all P<0.05). The optimal cut-off value was 22.35 kPa for LSM, 45.25 kPa for SSM, and 34.50 U/L for ADA in predicting severe EV, with an AUC of 0746, 0.802, and 0.791, respectively, a sensitivity of 82.8%, 75.9%, and 58.6%, respectively, and a specificity of 65.6%, 77.4%, and 90.2%, respectively. LSM+ADA, SSM+ADA, and LSM+SSM+ADA had an AUC of 0.826, 0.853, and 0.907, respectively, in predicting severe EV (all P<0.05). ConclusionLiver/spleen stiffness combined with serum ADA has a good value in predicting severe EV, which can provide a preliminary diagnostic basis for severe EV in patients who refuse to undergo gastroscopy.

ABSTRACT

BACKGROUND@#Aspirin has demonstrated safety and efficacy for venous thromboembolism (VTE) prophylaxis following total hip arthroplasty (THA); however, inconsistent dose regimens have been reported in the literature. This study aimed to evaluate and compare the safety and efficacy of 100 mg aspirin twice daily with rivaroxaban in VTE prophylaxis following THA.@*METHODS@#Patients undergoing elective unilateral primary THA between January 2019 and January 2020 were prospectively enrolled in the study and randomly allocated to receive 5 weeks of VTE prophylaxis with either oral enteric-coated aspirin (100 mg twice daily) or rivaroxaban (10 mg once daily). Medication safety and efficacy were comprehensively evaluated through symptomatic VTE incidence, deep vein thrombosis (DVT) on Doppler ultrasonography, total blood loss (TBL), laboratory bloodwork, Harris hip score (HHS), post-operative recovery, and the incidence of other complications.@*RESULTS@#We included 70 patients in this study; 34 and 36 were allocated to receive aspirin and rivaroxaban prophylaxis, respectively. No cases of symptomatic VTE occurred in this study. The DVT rate on Doppler ultrasonography in the aspirin group was not significantly different from that in the rivaroxaban group (8.8% vs. 8.3%, χ2 = 0.01, P = 0.91), confirming the non-inferiority of aspirin for DVT prophylaxis (χ2 = 2.29, P = 0.01). The calculated TBL in the aspirin group (944.9 mL [658.5-1137.8 mL]) was similar to that in the rivaroxaban group (978.3 mL [747.4-1740.6mL]) (χ2 = 1.55, P = 0.12). However, there were no significant inter-group differences in HHS at post-operative day (POD) 30 (Aspirin: 81.0 [78.8-83.0], Rivaroxaban: 81.0 [79.3-83.0], χ2 = 0.43, P = 0.67) and POD 90 (Aspirin: 90.0 [89.0-92.0], Rivaroxaban: 91.5 [88.3-92.8], χ2 = 0.77, P = 0.44), the incidence of bleeding events (2.9% vs. 8.3%, χ2 = 0.96, P = 0.33), or gastrointestinal complications (2.9% vs. 5.6%, χ2 = 1.13, P = 0.29).@*CONCLUSION@#In terms of safety and efficacy, the prophylactic use of 100 mg aspirin twice daily was not statistically different from that of rivaroxaban in preventing VTE and reducing the risk of blood loss following elective primary THA. This supports the use of aspirin chemoprophylaxis following THA as a less expensive and more widely available option for future THAs.@*TRIAL REGISTRATION@#Chictr.org, ChiCTR18000202894; http://www.chictr.org.cn/showproj.aspx?proj=33284.

ABSTRACT

Objective@#To understand the health education demands of primary and middle school students in Guiyang.@*Methods@#A multi-stage stratified cluster random sampling was used to conduct a questionnaire survey for 5 540 students in grades 3-9 in Guiyang.@*Results@#The report rate of dental caries decreases with the increase of school age(P<0.05), and the reporting rate of myopia and the appearance of sexual development characteristics increases with the increase of school age(P<0.05). Proportion of middle and primary school students who could get enough sleep every day(17.6% and 22.0%) and one hour of outdoor activities every day(13.9% and 20.9%) was relatively low.The proportion of graduating students with running away from home and suicide/self-injury ideas/plans and behaviors was higher than other grades in the same school period(P<0.05).The proportion of middle school female students who have thoughts/plans of running away from home, suicidal/self-injury plans and behaviors was higher than that of male students.Students with greater academic pressure,fewer friends,and lack of communication with their parents were more likely to have thoughts/plans or behaviors of running away from home and suicide/self-harm(P<0.05). There were 4 600 students(83.3%) who expressed the demands for health education.School was the primary source of health knowledge for students,with the class meetings accounted for the most practices.Health education on healthy behaviors and lifestyles were highly expected.@*Conclusion@#The health education demands of primary and middle school students in Guiyang show age and sex specific characteristics.Health education should follow the physical and psychological development characteristics of students and adapt to the needs of students.

ABSTRACT

The diagnostic accuracy of dermoscopy (DS) for scabies, a highly contagious parasitic disease, remains disputed. This study aimed to assess the diagnostic accuracy of DS in scabies, analyze the factors influencing DS, and explore its role in post-treatment evaluation. Patients with suspected scabies were randomly divided into 2 groups: 71 patients in the skin scraping (SS) group and 73 patients in the DS group. The diagnostic efficiencies of SS and DS in these groups were calculated. We also analyzed the influence of body part and investigator competence on the accuracy of DS. Then 16 body parts with typical signs of scabies were monitored by DS 2 and 4 day after sulfur ointment treatment. The sensitivity and specificity of DS were 98.3% and 88.5%, respectively. Hands, arms, and the abdomen had higher positivity rates than other body parts (P<0.001). The accuracy of dermatologists’ interpretations of images negative for scabies in the intermediate- and high-level groups was higher than that in the low-level group (P<0.001). At follow-up, the mites were still visible on 43.8% to 62.5% of the skin lesions 2 and 4 day after sulfur ointment treatment. These results showed that DS could significantly increase the accuracy of diagnosing scabies owing to its high sensitivity and specificity. Therefore, it may be useful for monitoring clinical responses to anti-parasitic treatment.

ABSTRACT

Objective To study the medical malpractice cases involving death, and discuss the identification ideas and methods of medical malpractice cases. Methods A total of 291 medical malpractice cases involving death accepted and settled from January 2012 to December 2017 at the Judicial Appraisal Center of Southern Medical University were collected. Based on the age, gender, hospital level, clinical department, whether or not autopsy was performed, cause of death, cause of medical mistakes, causality and causative potency of the appraised person, statistical analysis was made. Results There were more males than females in medical malpractice cases involving death. Mostly young adults or children were involved in these cases. The number of cases involving tertiary hospitals was the highest; among the clinical departments, the internal medicine department had the largest number of cases, followed by surgery, obstetrics and gynecology, pediatrics, etc. Autopsy rate has a trend of increasing year by year. Most patients die from the natural outcomes of their disease or ineffective treatment. Most hospitals have certain medical mistakes, and have an indirect correlation with the patient's death, mainly slight factors. Conclusion Judicial appraisal of medical malpractice should follow the principle of "one-effect and multi-cause", and comprehensively consider various factors such as, the diseases and constitution of the patient, natural outcomes of the diseases, the current medical technology and the level of diagnosis and treatment of the hospital, etc.

ABSTRACT

@#【Objective】To study the relationship between circulation tumor cell(CTC)and clinicopathological characteristics in early and middlestage colorectal cancer,and to evaluate the diagnostic and prognostic value of peripheral blood CTC through dynamically monitoring the changes of peripheral blood CTC in the patients before and after operation.【Methods】 Prospectively 67 patients with early and middle stage colorectal cancer were included,and 20 healthy volunteers served as contrast during the same period. Peripheral venous blood(7.5 mL)was collected 24 h before radical operation,3 months after radical operation and in control group. SE- iFISH technique was used to isolate and identify CTC. The cutoff value of CTC in diagnosis of colorectal cancer was determined by the receiver operating curve(ROC)and Youden index. Kaplan-Meier and log-rank methods were used for survival analysis and multivariate COX regression analysis for multivariate correction. The value of CTC in the diagnosis of early and middle stage colorectal cancer was evaluated comprehensively,and then the relationship between CTC in peripheral blood and clinicopathological characteristics and prognosis was synthetically evaluated combined with clinicopathological characteristics and postoperative follow- up data. 【Results】The positive rate of CTC in patients with early and middle stage colorectal cancer was significantly higher than that in healthy people(91.0% vs. 5.0% ,P<0.01). The CTC enumeration was significantly correlated with the depth of invasion and tumor location(P = 0.001,P = 0.044),but not with gender,age,tumor size,lymph node metastasis,TNM stage ,CEA level and CA-199 level. The preoperative CTC enumeration were not correlated with the above-mentioned clinicopathological parameters. Preoperative CTC had no predictive significance for disease free survival(DFS)and total survival(OS)(AUC = 0.359,P = 0.068;AUC = 0.428,P = 0.423),and postoperative CTC critical point of 3/7.5 mL had predictive significance for DFS and OS(AUC = 0.936 ,P < 0.001 ;AUC = 0.863 ,P < 0.001). It was found that patients with early and middle stage colorectal cancer were divided into two groups :good prognosis group(CTC < 3 after operation or the number of CTC after operation was equal or decreased with the number of CTC before operation)and bad prognosis group(CTC ≥ 3 after operation or the number of CTC after operation was higher than the number of CTC before operation). The DFS of the good prognosis group was significantly longer than that of the poor prognosis group (43.7 months vs. 20.4 months,P < 0.001;48.7 months vs. 26.8 months,P < 0.001),and the OS was also significantly longer (54.7 months vs. 43.3 months,P < 0.001;54.8 months vs. 45.1 months,P < 0.001). Multivariate analysis showed that CTC ≥ 3/7.5 mL was a bad independent factor of DFS and OS.【Conclusions】CTC has high clinical value in patients with early and middle stage colorectal cancer. Preoperative CTC values can not predict the prognosis of early and middle stage colorectal cancer ,but postoperative CTC values and dynamic detection for CTC changes before and after operation can independently predict the prognosis of early and middle stage colorectal cancer.

ABSTRACT

Objective To observe the influence of nape acupuncture therapy on swallowing function of patients with cerebral infarction. Methods Eighty patients with dysphagia after cerebral infarction were recruited and randomly allocated to the nape acupuncture group and the control group, 40 each group. Both groups were given general medicine therapy and swallowing functional training, while the nape acupuncture group was given nape acupuncture based on the control group, and fiberoptic nasopharyngoscopy was used for the swallowing function before and after treatment. Rosenbek Penetration-Aspiration Scale (PAS) score of 5ml pudding food, 5ml and 10ml liquid food, and the scores for bedside water-swallowing test and standardized swallowing assessment (SSA) were obtained. Before and after treatment, the differences between the two groups were identified respectively. Results After treatment, the scores of SSA and PAS of swallowing of 3 kinds of food in both groups were significantly improved compared with those before treatment (P<0.05). The improvement of SSA and PAS scores of 5ml and 10ml liquid food in the nape acupuncture group were superior to the control group (P<0.05). The total effective rate of the nape acupunture group was significantly higher than that of control group (χ2=5.00, P<0.05). Conclusion Nape acupuncture therapy may significantly improve the swallowing function of patients with dysphagia following cerebral infarction.

ABSTRACT

ABSTRACT Background: Clinical characteristics are keys to improve identification and treatment of Crohn´s disease (CD) so that large sample analysis is of great value. Aim: To explore the clinical characteristics of perianal fistulising CD. Methods: Analysis of 139 cases focused on their clinical data. Results: The proportion of males and females is 3.3:1; the mean age is 28.2 years; 47.5% of patients had anal fistula before CD diagnosis. Patients with prior perianal surgery and medication accounted for 64.7% and 74.1% respectively. The L3 type of lesion was present in 49.6% and the B1 and B2 types for 51.8% and 48.2% respectively; complex anal fistula was diagnosed in 90.6%. Symptoms of diarrhea were found in 46% and perianal lesions alone in 29.5% of patients. Abnormal BMI values was present in 44.6%; active CD activity index in 64.7%; and 94.2% had active perianal disease activity index. A proportion of patients manifest abnormal C-reactive protein, erythrocyte sedimentation rate, platelet, hemoglobin and albumin. Conclusion: We suggest that patients with anal fistula associated to these clinical features should alert the medical team to the possibility of CD, which should be further investigated through endoscopy and imaging examination of alimentary tract to avoid the damage of anal function by routine anal fistula surgery.

ABSTRACT

<p><b>Objective</b>To investigate the effect of Kangshuailing Gao (KG) on benign prostatic hyperplasia (BPH) in rats and its action mechanisms.</p><p><b>METHODS</b>Fifty BPH model rats were randomized into five groups of equal number, BPH model control, finasteride control, and high-, medium- and low-dose KG, to be treated intragastrically with distilled water, finasteride solution at 0.52 mg/kg, and KG solution at 4.16, 2.08 and 1.04 g/kg respectively once a day for 30 days consecutively. Another 10 normal healthy rats were taken as blank controls. The rats were weighed once a week during the treatment. The wet weight and index of the prostate were obtained after treatment, followed by measurement of the contents of serum estradiol (E2) and dihydrotestosterone (DHT), testosterone (T) and hypoxia-inducible factor-1α (HIF-1α) in the prostatic tissue, and observation of histomorphological changes in the prostate under the light microscope.</p><p><b>RESULTS</b>Compared with the BPH model control group, high- and medium-dose KG significantly reduced the prostate wet weight ([0.84 ± 0.08] vs [0.69 ± 0.04] and [0.71 ± 0.07] g, P < 0.01), the prostatic index ([0.28 ± 0.03]% vs [0.20 ± 0.02]% and [0.22 ± 0.03]%, P < 0.01), and the levels of T ([4.63 ± 1.25] vs [2.44 ± 0.47] and [2.91 ± 0.69] ng/L, P < 0.01) and DHT ([154.44 ± 20.25] vs [88.23 ± 13.63] and [90.52 ± 16.44] nmol/L, P < 0.01), but increased the level of E2 ([0.95 ± 0.24] vs [1.19 ± 0.14] and [1.20 ± 0.22] nmol/L, P < 0.01) in the serum. High-dose KG remarkably reduced the overexpression of HIF-1α in the prostate tissue of the BPH model rats (P < 0.01) and alleviated such BPH-related symptoms as epithelium thinning, intraglandular secretion reduction, and interstitial substance decrease.</p><p><b>CONCLUSIONS</b>Kangshuailing Gao acted effectively on BPH in the model rats by reducing the androgen level, balancing the estrogen/androgen ratio, and downregulating the expression of HIF-1α in the prostate tissue.</p>

ABSTRACT

Objective To compare the applicability of different occupational health risk assessment methods in small furniture manufacturing industry. Methods American EPA inhalation risk model, Singapore semi-quantitative risk assessment model of occupational exposure to chemical substances and Australian Occupational Health and Safety Risk Assessment model, were used to assess the occupational health risk in a small furniture manufacturing industry from a city of Zhejiang Province. Results The results of American EPA model showed that the workers who exposed to benzene and formaldehyde had low risk of carcinogens, and who exposed to benzene and xylene had very high risk of non-carcinogens. According to Singapore semi-quantitative risk assessment model, there were low and medium health risk caused by toluene and xylene, and high risk caused by wood dust in preparation and polishing jobs. Similar to the results of other models, Australia qualitative risk assessment model showed that there were medium health risk caused by toluene and xylene, and high risk caused by benzene, wood dust and noise. All of the three methods could found the key risk control point in furniture manufacturing industry. The risk ratios of the three methods were higher than the toxic work classification ratio (P<0.01), and the risk ratio of EPA model were higher than the results of Singapore model and Australia model (P<0.05) . Conclusion All of the three methods can be applied to assess the occupational health risk in furniture manufacturing industry, and the combined application of multiple risk assessment methods can be used as one of the risk assessment strategies.

ABSTRACT

Lead exposure is a known potential risk factor for neurodegenerative diseases such as Alzheimer's disease (AD). Exposure to lead during the critical phase of brain development has been linked with mental retardation and hypophrenia in later life. This study was aimed to investigate the effects of lead exposure of pregnant mice on the expressions of insulin-degrading enzyme (IDE) and nerve growth factor (NGF) in the hippocampus of their offspring. Blood samples were collected from the tail vein, and after anesthetizing the pups, the brain was excised on postnatal day 21. Lead concentrations were determined by graphite furnace atomic absorption spectrophotometry, and the expressions of IDE and NGF were determined by immunohistochemistry and Western blotting. Results showed that the reduction in IDE and NGF expression in the hippocampus of pups might be associated with impairment of learning and memory and dementia induced by maternal lead exposure during pregnancy and lactation.

ABSTRACT

Rational nutritional support shall be based on nutritional screening and nutritional assessment.This study is aimed to explore nutritional risk screening and its influencing factors of hospitalized patients in central urban area.It is helpful for the early detection of problems in nutritional supports,nutrition management and the implementation of intervention measures,which will contribute a lot to improving the patient's poor clinical outcome.A total of three tertiary medical institutions were enrolled in this study.From October 2015 to June 2016,1202 hospitalized patients aged ≥18 years were enrolled in Nutrition Risk Screening 2002 (NRS2002) for nutritional risk screening,including 8 cases who refused to participate,5 cases of same-day surgery and 5 cases of coma.A single-factor chi-square test was performed on 312 patients with nutritional risk and 872 hospitalized patients without nutritional risk.Logistic regression analysis was performed with univariate analysis (P<0.05),to investigate the incidence of nutritional risk and influencing factors.The incidence of nutritional risk was 26.35% in the inpatients,25.90% in male and 26.84% in female,respectively.The single-factor analysis showed that the age ≥60,sleeping disorder,fasting,intraoperative bleeding,the surgery in recent month,digestive diseases,metabolic diseases and endocrine system diseases had significant effects on nutritional risk (P<0.05).Having considered the above-mentioned factors as independent variables and nutritional risk (Y=1,N=0)as dependent variable,logistic regression analysis revealed that the age ≥60,fasting,sleeping disorders,the surgery in recent month and digestive diseases are hazardous factors for nutritional risk.Nutritional risk exists in hospitalized patients in central urban areas.Nutritional risk screening should be conducted for inpatients.Nutritional intervention programs should be formulated in consideration of those influencing factors,which enable to reduce the nutritional risk and to promote the rehabilitation of inpatients.
