Objective:To systematically evaluate the correlation between chronic periodontitis and postmenopausal osteoporosis (PMOP).Methods:Electronic searches were conducted on Cochrane Library, Pubmed, Embase, Ovid, CNKI, CBM, VIP, and WF databases to collect research literature on the correlation between chronic periodontitis and PMOP. The Newcastle Ottawa Scale (NOS) criteria were used to evaluate the quality of the included literature, and RevMan 5.3 software was used for meta-analysis. The outcome measures were clinical attachment loss (CAL), probing depth (PD), plaque index (PI), calculus index (CI), bleeding on probing (BOP), and simplified oral hygiene index (OHI-S).Results:A total of 16 articles were included, with a total of 1587 patients. Compared with the postmenopausal non osteoporosis group, the osteoporosis group showed significant abnormalities in CAL [standardized mean difference (SMD)=1.09, 95% CI: 0.62-1.57, P<0.001], PD(SMD=0.71, 95% CI: 0.28-1.14, P<0.001), PI(SMD=0.43, 95% CI: 0.29-0.56, P<0.001), and OHI-S(SMD=0.28, 95% CI: 0.22-0.35, P<0.001) indicators, as well as in BOP(SMD=0.01, 95% CI: -0.48-0.49, P=0.97) and GI(SMD=0.01, 95% CI: -0.48-0.49, P=0.97). At the level of 0.24 and 95% CI: -0.34 to 0.81, P=0.42, there was no statistically significant difference. Conclusions:Women with PMOP exhibit more significant changes in indicators such as CAL, PD, PI, and OHI-S, suggesting that postmenopausal women with osteoporosis are more likely to suffer from periodontitis.

In order to establish a rapid,specific and sensitive detection method for Streptococcus equi subspecies zooepidemicus(SEZ)and to understand the infection status of SEZ in horses ente-ring China,specific primers were designed and synthesized based on the conserved gene comB of standard strain SEZ(ATCC 43079)in this work.Then,the pMD19-T-comB recombinant plasmid was constructed and used as a standard positive template.After that,the fluorescence-based quantitative PCR(qPCR)detection method based on SYBR Green Ⅰ dye was established.Totally,477 equine entry serum samples from 6 countries,including Netherlands,Belgium,Japan,Germa-ny,Argentina and New Zealand,during 2018 to 2023,were randomly selected and detected for SEZ by the qPCR method.Results showed that the established qPCR method had specific amplification for only SEZ,which illustrated a good specificity.Sensitivity test of the method showed that the limited detection amount was 4.58 X101 copies/μL.And the repeatability test showed that the coef-ficient of variation of intra-batch repeatability was less than 0.5％,while the inter-batch repeat-ability was less than 3.0％,which indicated good repeatability and high stability.Retrospective a-nalysis showed that totally 11 of 477 positive samples were detected,with a relatively low positive rate of 2.31％(11/477).Among them,all the 40 samples from Netherlands in 2018 were negative(0/40).In the samples of 2019,one positive was detected from Belgium(1/20),while all other 36 samples which form Japan and Germany were negative.In the samples of 2021,three samples(3/34)from Japan and one sample(1/20)from Argentina were positive,and all the other 40 samples from the Netherlands were negative.In the samples of 2022,76 samples from Netherlands were all negative.While in the 2023,5(5/126)of 126 samples from Netherlands and one(1/88)of 88 from New Zealand were found positive with SEZ.To summarize,The SYBR Green Ⅰ qPCR method for the diagnosis of SEZ was successfully established,and it could provide necessary technical support for the rapid quarantine of China's entry-exit and port departments,as well as the epidemiological investigation of the disease.

ObjectiveTo investigate the feasibility of apical sodium-dependent bile salt transporter (ASBT) and asialoglycoprotein receptor (ASGPR) in the design of oral liver-targeting preparations for the treatment of hepatic alveolar echinococcosis (HAE) by measuring the expression of ASBT and ASGPR. MethodsA total of 18 male Sprague-Dawley rats were selected, among which 10 were used to establish a model of HAE (HAE group) and 8 were used as controls (normal group). Immunofluorescence assay, Western blotting, and quantitative real-time PCR were used to measure the expression distribution, protein expression level, and mRNA expression level of ASBT in the ileal tissue of HAE model rats and normal rats; the same methods were used to measure the expression level of ASGPR in the non-diseased liver tissue and the marginal zone of liver tissue lesion of HAE model rats and the liver tissue of normal rats. The t-test was used for comparison of normally distributed continuous data between two groups; a one-way analysis of variance was used for comparison between three groups, and the least significant difference t-test was used for comparison between two groups. ResultsThe results of immunofluorescence assay, Western blotting, and quantitative real-time PCR showed that compared with the normal group, the HAE group had significantly upregulated expression of ASBT in the ileal tissue (t=5309, 4.110, and 28.060, all P＜0.05) and a significantly higher expression level of ASGPR (the closer to the lesion, the higher the expression) (F=110666, 128.201, and 143.879, all P＜0.001). ConclusionASBT and ASGPR can be used as potential mediated receptors for oral liver-targeting preparations for HAE, which provides a theoretical basis for the design of oral liver-targeting preparations for the treatment of HAE.

Objective:To understand the content of fluorine in tea leachate in Shijiazhuang City.Methods:From 2017 to 2019, different varieties of tea (including 7 varieties of green tea, scented tea, dark tea, oolong tea, black tea, white tea, and yellow tea) with high sales volume were purchased at the Shijiazhuang Tea Market. The fluoride content in tea was determined by fluoride ion selective electrode method through different soaking time (5, 10, 15, 20 min) and soaking times (1, 2, 3 times).Results:A total of 82 tea samples were detected, including 25 kinds of green tea (30.49%), 5 kinds of scented tea (6.10%), 11 kinds of dark tea (13.41%), 17 kinds of oolong tea (20.73%), 15 kinds of black tea (18.29%), 7 kinds of white tea (8.54%) and 2 kinds of yellow tea (2.44%). After soaking for 20 min, the fluorine contents in tea leachate of green tea, oolong tea, black tea, and dark tea (40.63, 65.43, 26.39, 58.90 mg/kg) were significantly higher than those in 5 min(23.09, 32.24, 15.77, 32.00 mg/kg, P < 0.05). Taking the fluorine content of the tea leachate soaking for 20 min as the total fluorine content, oolong tea was the highest, with a median of 65.43 mg/kg; black tea was the lowest, with a median of 26.39 mg/kg; The fluorine contents of oolong tea, dark tea and scented tea were significantly higher than that of black tea( P < 0.05). With the increase of soaking times of green tea, oolong tea, black tea, dark tea and white tea, the fluorine contents in tea leachate decreased significantly ( P < 0.05). Conclusions:In this study, the content of fluorine in the oolong tea is the highest, and the lowest is black tea. It is suggested that local residents in Shijiazhuang should drink black tea.

Objective: To explore the influence of cluster nursing intervention on inadequate drainage in vacuum sealing drainage (VSD) for inpatients in burn unit. Methods: From October to December 2016, 60 patients, aged (43.6±2.8) years admitted to our department, receiving VSD treatment and conforming to the inclusion criteria, were included in the routine nursing group, and among the patients, 37 cases were male and 23 cases were female. From May to July 2017, 58 patients, aged (44.2±3.2) years admitted to our department, receiving VSD treatment and conforming to the inclusion criteria, were included in the cluster nursing group, and among the patients, 36 cases were male and 22 cases were female. The patients′ medical records were retrospectively analyzed. After VSD treatment, patients in routine nursing group received routine nursing, and patients in cluster nursing group received cluster nursing. A cluster intervention group was formed and headed by a chief surgeon. The cluster nursing plan was formulated and implemented strictly from the following six aspects of material preparation, negative pressure value control and negative pressure mode setting, drainage tube nursing, semi-permeable membrane reinforcement, standardizing changing process and timing of drainage capsule, and health education. During VSD treatment, the incidence of inadequate drainage, reasons of inadequate drainage and the occurrences, occurrences of inadequate drainage of wounds in different types and sites, and satisfaction of patients in two groups were observed and calculated. The patient satisfaction items included procedure of drainage capsule replacement, the method of tube fixation, the content and form of health education. Data were processed with independent sample t test and chi-square test. Results: (1) During VSD treatment, the incidence of inadequate drainage of patients in routine nursing group was 43.33% (130/300), which was significantly higher than 17.24% (50/290) in cluster nursing group (χ²=43.350, P<0.01). (2) During VSD treatment, the incidences of inadequate drainage caused by blockage of drainage tube due to scabbing of drainage, low negative pressure, air leakage of semi-permeable membrane, improper changing process of drainage capsule, shedding, compression, reversal of drainage tube of patients in cluster nursing group were 7.93% (23/290), 4.48% (13/290), 1.72% (5/290), 1.03% (3/290), and 2.07% (6/290), respectively, significantly lower than 16.67% (50/300), 11.67% (35/300), 4.33% (13/300), 4.00% (12/300), and 6.67% (20/300) in routine nursing group (χ²=10.379, 22.951, 4.832, 7.840, 7.399, P<0.05 or P<0.01). (3) During VSD treatment, the incidences of inadequate drainage of burn wounds, trauma wounds, pressure ulcer, venous ulcer in lower limbs, and diabetic foot of patients in cluster nursing group were significantly lower than those in routine nursing group (χ²=17.835, 6.809, 9.478, 4.939, 8.631, P<0.05 or P<0.01). During VSD treatment, the incidences of inadequate drainage of wounds in different types of patients in the same group were close (χ²=0.434, 0.057, P>0.05). (4) During VSD treatment, the incidences of inadequate drainage of wounds in limbs, trunk, buttocks, and sacrococcyx of patients in cluster nursing group were significantly lower than those in routine nursing group (χ²=31.892, 9.588, 4.939, 4.549, P<0.05 or P<0.01). During VSD treatment, the incidences of inadequate drainage of wounds in different wound sites of patients in the same group were close (χ²=0.071, 0.069, P>0.05). (5) The satisfaction scores in changing process of drainage capsule, method of tube fixation, content and form of health education of patients in cluster nursing group after VSD treatment were significantly higher than those in routine nursing group (t=5.166, 4.471, 7.958, 8.975, P<0.01). Conclusions Cluster nursing intervention on patients receiving VSD treatment could reduce the incidences of inadequate drainage of wounds in different types and sites caused by various reasons. It also can improve patient satisfaction.

At present, there are many monitoring devices for vital signs parameters for clinical selection, but urine monitoring has not received enough attention. The traditional manual visual measurement, intermittent measurement of urine pH value, and other methods are still in use, so the authors designed a multifunctional urine bag. The urine bag can set up an alarm system per unit time according to patient′s age and condition as well as set up urine pH value detection area in hard plastic measuring bottle. This device can not only accurately monitor urine volume per unit time, but also hopefully realize the alarm automation of abnormal urine volume per unit time, as well as real-time dynamic monitoring of urine pH value. It is helpful for medical staff to make accurate judgment on patients′ condition changes, to guide the formulation and modification of clinical treatment plans, and to reduce the workload of clinical nursing staff to a certain extent.

Objective: To explore the influences of comprehensive nursing intervention on the caregivers of severely burned children. Methods: Eighty severely burned children, admitted to our department from November 2016 to November 2017 and conforming to the study criteria, were included in this study. They were divided into comprehensive group and control group according to the random number table, with 40 children in each group. One caregiver for each child was included in the same group. Children and caregivers in control group had routine nursing care while children and caregivers in comprehensive group had comprehensive nursing care on the base of routine nursing care, including comprehensive psychological nursing of children and caregivers, guidance of rehabilitation for caregivers throughout the entire recovery process, individualized propaganda and education for caregivers on account of disease of children, perfecting social support system, sustained attention of children during follow-up. Anxiety self-rating scale and social support rating scale were used to assess the levels of anxiety and social support of caregivers of children in the two groups at the time of admission (before intervention) and the second month after discharge (the third time follow-up, after intervention). On the day of discharge, the nursing service satisfaction questionnaire of our department was used to evaluate the nursing service satisfaction of caregivers of children. Data were processed with chi-square test and independent sample t test. Results: (1) Before intervention, the anxiety and social support scores of caregivers of children in control group were respectively (64.5±3.8) and (40.4±2.5) points, similar to (63.5±4.9) and (40.5±2.6) points in comprehensive group (t=0.988, 0.177, P>0.05). After intervention, the anxiety score [(47.2±1.9) points] of caregivers of children in comprehensive group was significantly lower than that of control group [(57.6±4.3) points, t=13.917, P<0.01], and the social support score [(45.3±1.9) points] was significantly higher than (35.9±2.1) points in control group (t=-21.282, P<0.01). After intervention, scores of objective support, subjective support, and social support utilization in the social support evaluation rating of caregivers of children in comprehensive group were significantly higher than those in control group (t=12.678, -11.079, -10.031, P<0.01). (2) At the time of discharge, scores of clinical care, propaganda and education content and form in the nursing service satisfaction questionnaire of caregivers of children in comprehensive group were significantly higher than those of control group (t=-14.757, -15.627, -33.221, P<0.01). Conclusions Comprehensive nursing intervention method can effectively reduce the anxiety of the caregivers of severely burned children, help them to make better use of social support system, and improve the satisfaction of caregivers in nursing services.
