Objective:To determine the status of nutritional literacy and its influencing factors among the peritoneal dialysis (PD) patients. Methods:The patients who underwent PD and long-term follow-up in the Department of Nephrology,General Hospital of Eastern Theater Command between January and October,2023 were enrolled in this study. The status of nutritional literacy in the patients was assessed through collecting and analyzing the data on the patients' general information,the current nutritional status,and laboratory-and dialysis-related indicators. Results:The average score of nutritional literacy in the enrolled patients were (24.49±3.35). Significant differences in nutritional literacy scoring were observed in the different patient subgroups according to the patients' educational background,dialysis time or times of receiving multidisciplinary diet guidance (all P values<0.05). The nutritional literacy levels of PD patients were negatively correlated to the concentrations of serum calcium and prealbumin,and left ventricular posterior wall thickness,and postively correlated to prealbumin level(P<0.05). Basing on multiple linear regression analysis,the times of receiving multidisciplinary diet guidance,educational background and serum prealbumin level were identified as independent influencing factors for the nutritional literacy levels in PD patients,respectively (all P values<0.05). Conclusions:The present study showed that the nutritional literacy of PD patients was in the middle level. In clinical practice,to enhance multidisciplinary diet guidance and management at the early stage of PD could contribute to improve the nutritional status of PD patients. In addition,to increase the patients' nutritional knowledge and health management ability might be also helpful for the nutritional levels of PD patients.

In view of the problem of slow development of intensive care medicine in Xizang, the research team made full use of the national partner assistance to Xizang, gathered resources across all cities in Xizang, and formed a national academic platform for critical care medicine in plateau areas. Adhering to the academic orientation with hemodynamics as the main topic, critical care ultrasound as the bedside dynamic monitoring and evaluation method, and blood flow-oxygen flow resuscitation as the core connotation, we have achieved the goals of improving the critical care talent echelon throughout Xizang, driving the overall progress of intensive care medicine in Xizang, making a figure in China, and focusing on training of top-notch talents.

BACKGROUND: Core muscle functional strength training (CMFST) has been reported to reduce injuries to the lower extremity. However, no study has confirmed whether CMFST can reduce the risk of low back pain (LBP). OBJECTIVE: This study identified the effects of CMFST on the incidence of LBP in military recruits. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: We performed a prospective, open-label, randomized, controlled study in a population of young healthy male naval recruits from a Chinese basic combat training program. Participants were randomly assigned to either the core group or the control group. In additional to normal basic combat training, recruits in the core group underwent a CMFST program for 12 weeks, while recruits in the control group received no extra training. MAIN OUTCOME MEASURES: At the beginning of the study and at the 12th week, the number of participants with LBP was counted, and lumbar muscle endurance was measured. In addition, when participants complained of LBP, they were assessed using the visual analog scale (VAS) and Roland Morris Disability Questionnaire (RMDQ). RESULTS: A total of 588 participants were included in the final analysis (295 in the core group and 293 in the control group). The incidence of LBP in the control group was about twice that of the core group over the 12-week study (20.8% vs 10.8%, odds ratio: 2.161-2.159, P < 0.001). The core group had better lumbar muscle endurance at 12 weeks than the control group ([200.80 ± 92.98] s vs [147.00 ± 84.51] s, P < 0.01). There was no significant difference in VAS score between groups, but the core group had a significantly lower RMDQ score at week 12 than the control group (3.33 ± 0.58 vs 5.47 ± 4.41, P < 0.05). CONCLUSION This study demonstrated that the CMFST effectively reduced the incidence of LBP, improved lumbar muscle endurance, and relieved the dysfunction of LBP during basic military training.

OBJECTIVETo assess the acceptability and influence factors of early antiretroviral therapy (ART) among HIV-positive men who have sex with men (MSM) .

METHODSFrom June to August 2012, through convenience sampling, HIV-positive MSM who were willing to cooperate with the survey were selected from the Hangzhou and Ningbo AIDS prevention and control database. A total of 280 HIV-positive MSM who did not receive ART participated in the study.Using self-designed questionnaire, general demographic information, awareness of AIDS knowledge, sexual behavior, use of condom, current physical condition, awareness and attitude towards early ART were investigated.Excluding 60 HIV-infected MSM whose CD4(+)T count didn't meet the inclusion criteria, a total of 220 subjects were included in the analysis. Chi-square was used to compare the difference of early ART acceptance among subjects with different characteristics.Non-conditional logistic regression was used to analyze the influence factors of the acceptability of early ART.

RESULTSThe acceptance rate of early ART among HIV-infected MSM was 62.7% (138/220). Delaying the disease development, preventing partners from infection, not worrying others to suspect them of having HIV, and partners unknowing the HIV-infected status were the factors which had a relatively higher acceptance rate of early ART. Correspondingly, the acceptance rate was 68.8% (130/189), 68.7% (103/150), 78.4% (69/88) and 72.5% (74/102) respectively and the acceptance rate among subjects with opposite opinions or characteristics was 24.1% (7/29) , 50.0% (30/60), 52.7% (68/129) and 45.8% (58/107) respectively (chi-square values were 21.46, 6.43, 14.84 7.55, all P values <0.05).Logistic regression analysis showed that delaying the disease development (OR = 11.50, 95%CI:3.29-40.22) and preventing partners from infection (OR = 3.72, 95%CI:1.53-9.03) were inclined to the acceptance of early ATR.While concerning others' suspection of them having HIV (OR = 0.19, 95%CI:0.08-0.48) and partners knowing the HIV-infected status were inclined to unacceptance of ART(OR = 0.31, 95%CI:0.13-0.70).

CONCLUSIONThe acceptability of early ART among HIV-positive MSM is high. The recognition of early ART and concern of privacy leak are the major influence factors which can stimulate the acceptance of early ART.

BACKGROUNDOperative decision-making of Pilon fractures are of great challenges until now. The aim of this study was to investigate the guidance of the four-column theory in decision-making therapeutic strategies for Pilon fractures and its result.

METHODSOne hundred and ten cases (107 patients) of Pilon fractures classified by the four-column theory and treated by ORIF, were reviewed. According to the four-column classification scheme, lateral column of 85 cases, posterior column of 66 cases, medial column of 77 cases, and anterior column of 61 cases are involved. Among all the 110 cases, single column of 14 cases, two columns of 46 cases, three columns of 17 cases, and all of four columns of 33 cases are involved.

RESULTSOne hundred and eight cases have been followed up. The average follow up time is 14.7 months, varying between 7 and 52 months. The average healing time is 3.6 months, ranging from 2.5 to 8.0 months. Reduction of 86.1% reviewed Pilon cases are good or acceptable according to Burwell and Charley's Radiology Evaluation System. Ankle function of 87.1% cases are excellent or good according to the AOFAS evaluation system.

CONCLUSIONAs a simple and comprehensive classification, the four-column classification can contribute to reasonable operation decision-making and good prognosis of Pilon fracture.

OBJECTIVE: To explore the postmortem changes of cornea thickness measured by ultrasonic pachymetry. METHODS: Eleven rabbits were randomly divided into two groups: one group with intact corneal epithelium and another group without intact corneal epithelium. In the later group, the corneal epithelium of the rabbit was scraped using mechanical elimination method. The corneal thickness was monitored continuously by ultrasonic pachymetry at several postmortem interval points in rabbits of the two groups. The changes of corneal thickness and postmortem interval were explored by relative regression analysis. RESULTS: The thickness of the cornea showed a strong non-linear correlation with the postmortem interval in the group with intact corneal epithelium. The group with intact corneal epithelium showed the correlation coefficient 0.922 and the group without intact corneal epithelium showed the correlation coefficient 0.822, respectively. CONCLUSION The corneal thickness measured by ultrasonic pachymetry shows a potential value for estimating early postmortem interval. The intact corneal epithelium is a crucial factor for the measurement of cornea thickness by ultrasonic pachymetry.

OBJECTIVETo detect lymphangiogenesis by labeling the lymphatic endothelial marker, lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1), and study the prognostic relevance of lymphangiogenesis in laryngeal squamous carcinoma.

METHODSClinical files and specimens of 78 patients with histologically diagnosed laryngeal carcinoma were stained with LYVE-1 as a specific lymphatic endothelial marker. The lymphatic vessel density (LVD) was measured, and the correlation between LVD and clinicopathological features of the tumor cases was analyzed.

RESULTSThe mean LVD in laryngeal carcinoma (13.24 ± 5.09) was significantly higher than that in adult laryngeal papilloma (5.54 ± 3.15) and squamous dysplasia (6.76 ± 4.45, P < 0.05). The LVD of poorly differentiated tumors (15.74 ± 5.24) was significantly higher than that in the moderately differentiated tumors (13.84 ± 6.20), and the LVD in the moderately differentiated tumors was significantly higher than that in the well-differentiated tumors (11.68 ± 6.34). The LVD in stage 0 to stage II group (10.66 ± 5.70) was significantly lower than that in the stage III to IV group (17.01 ± 6.35). The lymph node metastasis group (17.25 ± 7.37) was significantly higher than non-lymph node metastasis group (8.60 ± 5.23, P < 0.05). There was no significant association between LVD and age, sex, primary site and distant metastasis. The overall survival in the patients with a LVD higher than the mean value was 33.5 month, and that of cases with a LVD lower than the mean value was 81.6 month (P < 0.05). The multivariate survival analysis showed that the clinical stage and LVD were independent prognostic factors of laryngeal cancer.

CONCLUSIONSThe LYVE-1 staining histochemistry demonstrates that the lymphangiogenesis occurrs mainly at the edge of the tumors, and lymphangiogenesis plays an important role in the carcinogenesis, cancer progression and lymph node metastasis in laryngeal cancer. LVD may be an independent indicator of poor prognosis of laryngeal cancer.

BACKGROUNDThe morbidity and mortality of prostate cancer have been increasing rapidly in recent China. There were few studies investigating prostate-specific antigen (PSA) values ranges in the healthy Chinese population. We performed this study to determine the distribution of serum PSA in a large healthy Chinese population.

METHODSFrom January 2001 to May 2008, 11 150 healthy Chinese men aged 30 - 79 years came to our hospital for routine health check-up. All subjects without a previous diagnosis of prostate cancer, a history of prostate surgery, or urogenital tract infection were proposed to undergo systematic serum PSA measurement and digital rectal examination (DRE). Men with normal DRE and PSA ≤ 4.0 ng/ml and those PSA > 4.0 ng/ml or abnormal DRE but without adverse findings on prostate biopsy were included (n = 9358). Age and serum PSA concentration were recorded and correlated through Logistic regression analysis.

RESULTSThe 95th percentile serum PSA concentration was 1.89 ng/ml for men aged 30 to 39 years, 2.19 ng/ml for men aged 40 to 49 years, 2.88 ng/ml for men aged 50 to 59 years, 4.42 ng/ml for men aged 60 to 69 years, and 6.52 ng/ml for men aged 70 to 79 years. The serum PSA concentration correlated with age (P < 0.0001) with an annual increase of 0.97% for men in 40 years, 1.58% for men in 50 years, 3.04% for men in 60 years, and 3.99% for men in 70 years.

CONCLUSIONSThe serum PSA level correlates directly with age in Chinese men older than 40 years, not in Chinese men younger than 40 years old. Chinese men have lower PSA level compared with white men above 60 years of age, not in those under 60 years of age.

BACKGROUNDRandomized studies have shown beneficial effects of drug-eluting stent (DES) in reducing the risk of repeated revascularization. Other studies have shown higher proportion of death, myocardial infarction (MI) and increased cost concerning DES. However the long term safety and effectiveness of DES have been questioned recently.

METHODSTo compare long term clinical outcomes, health-related quality of life (HRQOL) and cost-utility after sirolimus-eluting stent (SES) and bare metal stent (BMS) implantation in angina patients in China, 1241 patients undergoing percutaneous coronary revascularization (PCI) with either SES (n = 632) or BMS (n = 609) were enrolled continuously in this prospective, nonrandomized, multi-center registry study.

RESULTSTotally 1570 stents were implanted for 1334 lesions. Follow-up was completed in 1205 (97.1%) patients at 12 months. Rates of MI, all causes of death were similar between the two groups. Significant differences were found at rate of cardiovascular re-hospitalization (136 (22.4%) in BMS group vs. 68 (10.8%) in SES group, P = 0.001) and recurrent angina (149 (24.5%) vs. 71 (11.3%), P = 0.001). Dramatic difference was observed when compared the baseline and 9-month HRQOL scores intra-group (P < 0.001). However no significant difference was found inter-group either in baseline or follow-up HRQOL. Compared with SES, the total cost in BMS was significantly lower on discharge (62 546.0 vs. 78 245.0 Yuan, P = 0.001). And follow-up expenditure was remarkably higher in the BMS group than that in the SES group (13 412.0 vs. 8 812.0 Yuan, P = 0.0001).

CONCLUSIONSThere were no significant differences on death, in-stent thrombosis, MI irrespective of stent type. SES was superior to BMS on improvement of life quality. SES was with higher cost-utility compared to BMS.

BACKGROUNDAlthough thrombolytic therapy with rescue percutaneous coronary intervention (PCI) is a common treatment strategy for ST-segment elevation acute myocardial infarction (STEMI), scant data are available on its efficacy relative to primary PCI, and comparison was therefore the aim of this study.

METHODSThis multicenter, open-label, randomized, parallel trial was conducted in 12 hospitals on patients (age < or = 70 years) with STEMI who presented within 12 hours of symptom onset (mean interval > 3 hours). Patients were randomized to three groups: primary PCI group (n = 101); recombinant staphylokinase (r-Sak) group (n = 104); and recombinant tissue-type plasminogen activator (rt-PA) group (n = 106). For all patients allocated to the thrombolytic therapy arm, coronary angiography was performed at 90 minutes after drug therapy to confirm infarct-related artery (IRA) patency; rescue PCI was performed in cases with TIMI flow grade < or = 2. Bare-metal stent implantation was planned for all patients.

RESULTSAfter randomization it required an average of 113.4 minutes to start thrombolytic therapy (door-to-needle time) and 141.2 minutes to perform first balloon inflation in the IRA (door to balloon time). Rates of IRA patency (TIMI flow grade 2 or 3) and TIMI flow grade 3 were significantly lower in the thrombolysis group at 90 minutes after drug therapy than in the primary PCI group at the end of the procedure (70.5% vs. 98.0%, P < 0.0001, and 53.0% vs. 85.9%, P < 0.0001, respectively). Rescue PCI with stenting was performed in 117 patients (55.7%) in the thrombolytic therapy arm. Rates of patency and TIMI flow grade 3 were still significantly lower in the rescue PCI than in the primary PCI group (88.9% vs. 97.9%, P = 0.0222, and 68.4% vs. 85.0%, P = 0.0190, respectively). At 30 days post-therapy, mortality rate was significantly higher in the thrombolysis combined with rescue PCI group than in primary PCI group (7.1% vs. 0, P = 0.0034). Rates of death/MI and bleeding complications were significantly higher in the thrombolysis with rescue PCI group than in the primary PCI group (10.0% vs. 1.0%, P = 0.0380, and 28.10% vs. 8.91%, P = 0.0001, respectively).

CONCLUSIONSThrombolytic therapy with rescue PCI was associated with significantly lower rates of coronary patency and TIMI flow grade 3, but with significantly higher rates of mortality, death/MI and hemorrhagic complications at 30 days, as compared with primary PCI in this group of Chinese STEMI patients with late presentation and delayed treatments.
