ABSTRACT

Objective:To discover the clinical features of nocturnal enuresis (NE) in adults and to detect factors that correlated with the symptom severity.Methods:This cross-sectional study recruited NE subjects from September 2017 through December 2020. All patients had experienced enuresis at least once per week and with a symptom duration of 3 months or longer. Followed by documentation of history and medical records, three-day bladder diary was adopted to assess their voiding pattern, and urodynamic parameters were obtained to evaluate lower urinary tract function.Results:A total of 106 NE patients (43 male and 63 female) were identified. There is no statistical difference regarding the average age (men: 57.8±15.6 vs. women: 56.1±14.0, P>0.05) and BMI (men: 23.9±3.4 vs. women: 23.3±4.3, P>0.05) between men and women. Comorbidities are extremely common in NE patients (n=85, 80.2%), with the incidence rate higher in men compared to women [88.4% (38/43)vs. 74.6% (47/63), P<0.05]. Hypertension (n=58, 54.7%), hyperlipemia (n=41, 38.7%), diabetes mellitus (n=38, 35.8%), coronary heart disease (n=22, 20.8%) were the most frequently reported conditions. On bladder diaries, subjects were frequently manifested nocturnal polyuria (NP, 47/106, 44.3%), reduced nocturnal bladder capacity (NBC, 74/106, 69.8%), or combination of both(33/106, 31.3%). Urodynamic studies suggested that the incidence of reduce bladder compliance, detrusor overactivity (DO), stress incontinence, bladder outlet obstruction(BOO), detrusor underactivity(DU)and detrusor hyperreflexia with impaired contractility(DHIC)was 27.4%(29/106), 39.6%(42/106), 17.9%(19/106), 9.4%(10/106), 25.5%(27/106)and 15.1%(16/106), respectively. Women were more likely to suffer from stress urinary incontinence [2.3%(1/43) men vs. 28.6% (18/63) women, P<0.01], while men were prone to have bladder outlet obstruction [ 23.3%(10/43) men vs. 0 women, P<0.01]. Correlation analysis demonstrated that obesity( r=0.63, P<0.01), systemic comorbidities( r=0.40, P<0.01), presence of NP( r=0.50, P<0.01) and NP+ NBC( r=0.47, P<0.01), post-void residual( r=0.53, P<0.01), reduced compliance( r=0.21, P=0.04), DU( r=0.28, P<0.01), stress incontinence( r=0.42, P<0.01)and DHIC ( r=0.35, P<0.01)are positively correlated with NE severity. Whereas, reduced Q max( r=-0.35, P<0.01), low capacity( r=0.21, P=0.03), and reduced bladder sensation( r=-0.21, P=0.03) correlate negatively with NE severity. Conclusions:The presence of NE is not only a sign of bladder dysfunction, but also an implication of obesity, systematic chronic diseases, urine production malfunctioning. Therefore, a thorough history regarding the lower urinary tract function and systemic comorbidities should be taken carefully, so that, an integrated and personalized treatment can be carried out.

ABSTRACT

Objective:To investigate the safety and efficacy of sacral neuromodulation(SNM)therapy for the treatment of lower urinary tract dysfunction(LUTD)in elderly patients.Methods:Clinical data of 91 elderly patients with LUTD from multiple medical institutions who received SNM during the period from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into four groups: the interstitial cystitis(IC)group(n=28), the neurogenic bladder(NB)group(n=36), the overactive bladder syndrome(OAB)group(n=13)and the idiopathic dysuria(ID)group(n=14). Different sets of evaluation parameters were used for different diseases.Patients’ baseline data and data in stage I(test phase)and stage Ⅱ(permanent SNM)were recorded, statistically analyzed and compared.Results:Ninety-one people underwent SNM treatment.Of them, 53 patients received permanent implants(stage Ⅱ), and the total conversion rate of stage I to stage Ⅱ was 58.2%(53/91). Patients receiving permanent implants(stage Ⅱ)had a preoperative period ranging from 3 months to 30 years, and were followed up for 2 to 58 months after treatment, with an average follow-up of 19.6 months.The improvement rates in stage I for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 35.4%, 31.6%, 33.7%, 32.6%, 49.2%, 43.2% and 13.2%, respectively.The improvement rates in stage Ⅱ for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 43.2%, 40.0%, 37.8%, 50.5%, 70.5%, 70.4% and 43.2%, respectively.Three adverse events occurred, including 1 case of recurrent symptoms, 1 case of moderate infection, and 1 case of electrical lead dislocation.Conclusions:Sacral nerve stimulation has definitive and consistent curative effects on LUTD in elderly people.The follow-up time should be extended to further study the safety of sacral nerve stimulation.

ABSTRACT

Objective:To explore the clinical predictive effect of the preoperative ratio of C reactive protein to albumin (CAR) on perioperative delirium (POD) in geriatric patients with femoral intertrochanteric fracture.Methods:The clinical data were analyzed retrospectively of the 398 patients who had undergone surgery for femoral intertrochanteric fractures at Department of Orthopedics, Xuanwu Hospital from January 2013 to March 2016. According to the presence or absence of POD, all the patients were divided into 2 groups: a delirium group and a normal group. The 2 groups were compared in terms of general clinical data like gender, age, body mass index, blood routine, CAR, biochemical indicators, blood coagulation indicators and concomitant internal diseases. After a single factor logistic regression analysis of the general clinical data of the patients, factors with P<0.10 were introduced into the multivariate logistic binary regression model to screen out the risk factors for POD in geriatric patients with femoral intertrochanteric fracture. The receiver operating characteristic (ROC) curve was drawn to analyze the predictive value and optimal cut-off point of CAR for POD in geriatric patients with femoral intertrochanteric fracture. Results:The incidence of POD in this cohort was 14.32%(57/398). The age, C-reactive protein, CAR, platelet and probability of pulmonary infection in the delirium group were significantly higher than those in the normal group, but the hemoglobin, albumin and prealbumin in the former were significantly lower than those in the latter ( P< 0.05). The multivariate logistic binary regression analysis showed that hemoglobin ( OR=0.975, 95% CI: 0.957 to 0.993, P=0.006) and CAR( OR=53.713, 95% CI: 17.713 to 162.876, P<0.001) were risk factors for POD in geriatric patients with femoral intertrochanteric fracture. The area under ROC of CAR in predicting POD in geriatric patients with femoral intertrochanteric fracture was 0.906 (95% CI: 0.873 to 0.933, P<0.001), and the cut-off point was 2.06. When CAR>2.06, its predicted incidence of POD was 50.50%, with a sensitivity of 89.47% and a specificity of 85.34%. Conclusion:As CAR is a risk factor for POD in geriatric patients with femoral intertrochanteric fracture, it can be used as an effective indicator to predict POD.

ABSTRACT

The angiogenic capacity of vascular endothelial cells is influenced by multiple mechanical factors. Mechanical factors guide the rearrangement of cytoskeleton, mediate intracellular signal transduction, affect cell migration, orientation and other behaviors, and then regulate their angiogenic capacity. However, different types of mechanical stimulation have different effects on their angiogenic capacity. This article summarizes and discusses the research work and progress of the influence of five mechanical factors (shear force, stretch stress, low-intensity pulsed ultrasound, microgravity, material properties) on vascular endothelial cell angiogenesis, which provides a basis and ideas for in-depth research of vascular biomechanics.

ABSTRACT

Purpose@#Titanium implants are widely used in the treatment of dentition defects; however, due to problems such as osseointegration failure, peri-implant bone resorption, and periimplant inflammation, their application is subject to certain restrictions. The surface modification of titanium implants can improve the implant success rate and meet the needs of clinical applications. The goal of this study was to evaluate the effect of the use of porous titanium with a chitosan/hydroxyapatite coating on osseointegration. @*Methods@#Titanium implants with a dense core and a porous outer structure were prepared using a computer-aided design model and selective laser sintering technology, with a fabricated chitosan/hydroxyapatite composite coating on their surfaces. in vivo and in vitro experiments were used to assess osteogenesis. @*Results@#The quasi-elastic gradient and compressive strength of porous titanium implants were observed to decrease as the porosity increased. The in vitro experiments demonstrated that, the porous titanium implants had no biological toxicity; additionally, the porous structure was shown to be superior to dense titanium with regard to facilitating the adhesion and proliferation of osteoblast-like MC3T3-E1 cells. The in vivo experimental results also showed that the porous structure was beneficial, as bone tissue could grow into the pores, thereby exhibiting good osseointegration. @*Conclusions@#Porous titanium with a chitosan/hydroxyapatite coating promoted MC3T3-E1 cell proliferation and differentiation, and also improved osseointegration in vitro. This study has meaningful implications for research into ways of improving the surface structures of implants and promoting implant osseointegration.

ABSTRACT

Microplastics refer to plastic particles with a diameter of less than 5 mm. Because of their wide distribution in the environment, it has gradually become one of the environmental hot issues of global concern in recent years. Microplastics are characterized by small particle size and strong adsorption. Existing studies have confirmed the biotoxic effects of microplastics in marine organisms and in experimental animals, suggesting their potential harm to human health. However, there have been few studies on the effects of microplastics on human health, and the research results have been inconsistent. Therefore, by summarizing the recent domestic and foreign studies about human exposure to microplastics as well as their potential effects on human body, this paper provides ideas and theoretical basis for further exploring the effects of microplastics on human health and related mechanisms.

ABSTRACT

It is well known that parenteral and enteral nutrition support is helpful to improve clinical outcomes in patients with malnutrition or nutritional risk, and surgical nutrition has been used in China for 40 years. However, there is still insufficient awareness of malnutrition among clinical workers. There were different opinions from many experts after the publications of the European Society for Parenteral and Enteral Nutrition (ESPEN) consensus of malnutrition assessment 2015 and ESPEN guidelines on definitions and terminology of clinical nutrition 2017. Global Leadership Initiative on Malnutrition (GLIM) criteria for the diagnosis of malnutrition has also been published in 2018. Though it is lack of clinical validation, it is a big step forward. In order to achieve better prevention and treatment of malnutrition in clinical work, this present paper analyzes and compares the core contents of malnutrition assessment (diagnosis) in recent years, proposes current practical strategy for Chinese clinical workers, emphasizes that GLIM criteria cannot replace the three steps named "screening-assessment-intervention" .

ABSTRACT

Objective@#The aim was to investigate the genotype distribution of two major epitopes of large surface protein (PreS1) of hepatitis B in Chinese patients and to explore the association between the genotypes of these two epitopes, and to determine whether PreS1 full-length genotype could be revealed according to the polypeptide sequence of key epitopes. @*Methods@#HBV DNA was extracted from the serum of patients for PCR amplification. 278 samples amplified successfully were sequenced and compared with the known HBV sequences in Genbank to determine the two key epitopes of HBV PreS1 genotype (amino acid epitope 21-47 and 94-117, abbreviated as P21 and P94) and PreS1 full-length genotypes. The correlation among three genotyping approaches was analyzed by Cohen’s kappa coefficient to verify the consistency between the key-epitope genotyping and the full-length preS1 genotyping. @*Results@#232 samples were successfully sequenced. The genotyping based on the kind of P21 epitope protein sequence, 201 cases for genotype C, 23 cases for genotype B and 8 cases for uncertain genotypes and genotyping based on the form of P94 epitope protein sequence, 199 cases for genotype C, 25 cases for genotype B and 8 cases for indeterminate genotypes. Lastly, the genotyping based on sequence of the full-length PreS1 sequence, 207 and 25 cases for genotype C and B. P21 or P94 epitope genotyping and PreS1 full length genotyping were highly consistent, respectively, 96.55% and 96.12%, and the two epitopes (P21and P94) genotyping have parallel consistency (93.10%). @*Conclusion@#In this study, an innovatively genotyping method based on the amino acid sequence of key epitopes was proposed. The genotypes of HBV in china were mainly B and C genotypes, and the genotypes of key conserved epitopes of HBV PreS1 were highly consistent with the full-length genotyping ( > 96%). Moreover, genotyping with one or two key epitopes can be used in place of the full-length genotyping.

ABSTRACT

Objective@#The effect and mechanism of cadmium telluride quantum dots (CdTe QDs) on cytochrome P450 (CYP450) in the liver of rat were investigated.@*Methods@#CdTe QDs (Ex 350 nm, Em 600 nm) were incubated with microsomes in final concentrations (0.5, 5, 50 μmol/L) using rat liver. And the content of CYP450 was determined by mixed incubation system as time (15, 30, 45 min) went on. Relationship also was detected between particle sizes (Em 620, 580, 540 nm; CdTe QDs-2, CdTe QDs-3, CdTe QDs-4) and expression of CYP450. Twenty male Wistar rats were randomly divided into exposed groups at various concentrations (0.25, 2.5 and 12.5 μmol/kg) of CdTe QDs via tail vein injection, the control group was injected with PBS.@*Results@#In vitro, CdTe QDs(0.5, 5, 50 μmol/L) could significantly increase the content of CYP450 in rat liver microsomes(P<0.05), which increased first and then decreased with the dose adding. Moreover, the trend along with the exposure time (15, 30, 45 min) was the same as that in dosages at certain concentration (P<0.01). For different particle sizes, the smaller CdTe QDs were, the higher content increased, the content of CYP450 in group CdTe QDs-4 was the highest (P<0.05). In vivo, experiment proved that CdTe QDs (0.25, 2.5 and 12.5 μmol/kg) could obviously induce the expression of CYP450 (P<0.01). The content level showed a tendency to rise and then fall.@*Conclusion@#CdTe QDs could promote the content of CYP450 in rat liver microsomes, it indicated that CdTe QDs had dose-effect relationship both in vivo and vitro. There was a certain relationship in time-effect. In addition, the smaller particle size was, the greater impact had.

ABSTRACT

Objective@#To compare the application of iASSIST assisted total knee arthroplasty (TKA) and three-dimentional(3D) printing personal specific instrument (PSI) assist TKA in the treatment of osteoarthritis (OA).@*Methods@#Clinical data of 47 patients with OA admitted at Department of Orthopaedic Surgery in Nanjing Medical University Nanjing Hospital between April and September 2016 were retrospectively reviewed, including 20 males and 27 females, aging from 57 to 77 years with mean age of (63.8±8.2) years. They were randomly divided into iASSIST-TKA group (23 patients) and PSI-TKA group (24 patients). The data such as hip knee ankle (HKA) angle, frontal femoral component (FFC) angle, frontal tibial component (FTC) angle, lateral femoral component (LFC) angle, lateral tibial component (LTC) angle, time of operation, post-operative wound drainage, period of hospitalization, visual analog scale (VAS) and Knee Society Score (KSS) at 1 day, 7 days, 14 days, 1 month and 3 months were recorded and compared between the two groups. T test was used to compare measurement data, Fisher exact test and χ2 test were applied to enumeration data in comparison among groups, and Kruskal-Wallis test was applied to ranked data.@*Results@#The deviation values of HKA, FFC, LFC, FTC and LTC angles were all below 3°(-2° to 2°), and there were no significant difference between iASSIST-TKA group and PSI-TKA group (Z=-0.610 to 0.000, P=0.542 to 1.000). Compared to PSI-TKA group, the time of operation was long((80.7±8.8) minutes vs.(60.2±7.8) minutes), the amount of post-operative wound drainage was increased((210.7±32.1) ml vs.(185.5±30.2)ml) and the period of hospitalization decreased((5.4±2.4) d vs.(6.7±1.6) d) in iASSIST-TKA group, there were significant difference(t=-2.190 to 8.460, P=0.000 to 0.033). There were no significant difference in intra-operative blood drainage((18.4±5.4) ml vs.(17.3±6.2) ml) between the two groups(t=0.650, P=0.521). PSI-TKA group had a superior VAS score(4.8±0.6 vs. 5.5±0.9, 3.6±0.8 vs. 4.3±0.9), KSS clinical score(49.3±5.5 vs. 44.2±6.4, 54.9±4.0 vs. 50.8±4.2) and KSS function score(44.1±2.9 vs. 41.2±3.5, 49.6±3.8 vs. 46.6±3.2) in 1 day and 7 days post-operation(t=-3.420 to 3.150, P=0.001 to 0.007). There were no significant difference in VAS and KSS score in 14 days, 1 month and 3 months post-operation(t=-1.390 to 0.530, P=0.170 to 1.000) between the two groups.@*Conclusions@#The iASSIST-TKA and PSI-TKA can help to make TKA procedure more accurately. iASSIST-TKA may take longer time of operation and have slower recovery, PSI-TKA may need more X-ray input and longer period of hospitalization. The long-term research of both techniques may be valuable for the further clinical usage.

ABSTRACT

Objective To investigate the recognition of nurses and patients on chosing daily caregivers and analyze the influencing factors. Method Totally 1,119 nurses and 1,134 patients from five first-class and two second-class hospitals in Zhuhai participated in the survey using self-designed questionnaires from April to June in 2014. Results There were significant differences between nurses and patients in all life nursing projects (P<0.001) except making beds for patients. The top three factors influencing the nurses′recognition were shortage of nursing staff and time, less presence of professional values and feeling no respects. The top three factors influencing the patients′recognition included tending to be nursed by family members, worries about medical expenses, and nurses′being too busy on treatment. Conclusion The different recognitions of nurses and patients on daily caregivers are influenced by multiple factors. Therefore , nursing managers should take some effective strategies to change the concepts of nurses and patients so as to improve quality of nursing service.

Objective To investigate prospectively the nutritional risks,undernutrition,and nutritional support in hospitalized patients with later but non-end-stage malignancies in a second grade hospital in Beijing.Methods All patients who were admitted in the department of oncology in this hospital from October 2011 to April 2013 were consecutively recorded.Nutritional Risk Screening (NRS 2002) was used for screening nutrition risks,the undernutrition assessment was performed on the first morning for patients meet the inclusion criteria,and nutritional support was evaluated until the discharge.For patients with no nutritional risk,NRS 2002 was repeated weekly during the hospitalization.Results A total of 305 cases of inpatients admitted,and 224cases meeting the inclusion criteria were screened by NRS 2002,among whom only 171 patients with non-endstage later stage cancer entered the final analysis.Among these 171 patients,116 (67.8%) were at nutritional risks.Furthermore,for different types of tumor,the nutritional risk was 45.7% for lung cancer,89.4% for digestive-tract cancers,81.3% for liver-biliary and pancreatic cancers,and 83.3% for head-and-neck cancers.The undernutrition rate was 12.3% (21/171) if based on body mass index < 18.5 kg/m2 and 19.9% (34/171) if evaluated from the score of nutritional defect part of NRS 2002.Only 71 patients (61.2%) at nutritional risk received nutritional support,while 5 of 55 patients (9.1%) without nutritional risk received nutritional support.The average ratio of parenteral nutrition to enteral nutrition was 23∶ 1.Intravenous calories intake was 56.78 ± 8.20 k J/ (kg · d) ; the intake of nitrogen was 0.06 ± 0.01 g/ (kg · d),and the ratio of calories to nitrogen was 204∶ 1.Conclusions A large proportion of inpatients with non-end-stage later cancer were at nutritional risk,which is associated with tumor types.The application of nutritional support should be further standardized,particularly for patients at nutritional risk but with low nutritional support.Furthermore,whether the clinical outcome of inpatients at nutritional risk may be improved by nutritional support still requires further investigation.

ABSTRACT

ObjectiveTo explore the ideal minimally invasive surgical method for degenerative lumbar spine stenosis.MethodsFrom March 2008 to August 2010,73 cases with lumbar spinal stenosis underwent minimal invasive surgery were retrospectively analyzed.The patients were divided into different groups by clinical features,imaging manifestations,and concurrent diseases.The minimal invasive surgical methods were chosen according to the classification.Operation time,intra-operative bleeding,and complications were recorded.The lumbar function was evaluated by Oswestry disability index (ODI),and the clinical results were assessed by JOA pre- and postoperatively.ResultsMinimal invasive surgery was completed in all cases,which included 25 cases with bilateral decompression and 48 cases with unilateral approach for bilateral decompression.Twenty-three cases used interbody fusion and percutaneous pedicle screw fixation after decompression.Intraoperative blood loss and operation time were related to surgical methods.One case was complicated with dural tear.Cage was inserted into upper vertebral body during interbody fusion in 1case with osteoporosis,removed the cage and implanted bone fusion.Incisions of 3 cases were poor healing after surgery.The average follow up time was 13 months(range,10-35).JOA score and ODI before surgery were 9.2±5.1 and 62.3%±18.5% respectively; while 6 months after surgery,JOA score and ODI were 23.5±7.2 and 18.4%±6.4% respectively.JOA score and ODI showed statistically significant improvements after operation(P<0.01).Twenty-two cases got solid fusion at the final follow-up.ConclusionTreatment of lumbar spinal stenosis by minimal invasive surgery has satisfactory surgical outcomes,but the proper minimal invasive strategy should be chosen according to specific patients,surgeons and hospitals.
