Abstract: Objective　The tuberculosis data of students registered and reported in Xuzhou from 2016 to 2020 were analyzed to provide a basis for Xuzhou to formulate tuberculosis prevention and control measures in schools. Method　The epidemiological characteristics of tuberculosis among students in Xuzhou from 2016 to 2020 were analyzed based on the data from Tuberculosis Information Management System and Xuzhou Statistical Yearbook 2021. Results　From 2016 to 2020, a total of 574 student tuberculosis patients were registered in Xuzhou, with an annual average registration rate of 5.64/100 000. The reported incidence of tuberculosis among students in Xuzhou showed an increasing trend year by year (χ2trend=22.521, P<0.001). There were 365 males and 209 females, respectively, with a sex ratio of 1.75:1. The tuberculosis patients were mainly in the 15-19 years old group and 20-24 years old group. According to the statistical analysis by different levels of education, students from ordinary higher institutions accounted for 48.61% of the total number of confirmed cases, followed by senior high schools and secondary vocational schools, accounting for 20.91% and 14.46%, respectively. Preschool education had the lowest number of confirmed cases, accounting for 1.05%. There was significant difference in the reported incidence of tuberculosis among students at different educational levels (χ2=1 522.39, P<0.001). The highest incidence was reported in ordinary higher institutions, followed by senior high schools and secondary vocational schools, and the lowest incidence was reported in preschool education. Conclusion　Xuzhou city school tuberculosis epidemic integral is on the rise, we should further strengthen tuberculosis control work of school tuberculosis prevention and control measures of implementation in the future, at the same time to strengthen school tuberculosis prevention knowledge propaganda and standardize the schools for disposal of tuberculosis epidemic situation. We should also further strengthen the newborn matriculation examination and students absent from class because of illness monitoring work.

Neuropathic pain is the clinically common disease and does great harm to physical and mental health.Because its pathogenesis is still unclear and there aren′t effective therapeutic tools and the course of chronic pain lasts a long time,the study of neuropathic pain has become the hot spot and the focal point of pain research area.This article reviews various kinds of animal models of neuropathic pain,which can repeat neuropathic pain symptoms of mankind and may be effective ways to make research.By acting on P2X receptors,ATP is the signal of an important transmitting pain.By utilizing animal models of neuropathic pain,it shows that P2X receptors have an important role in the formation,transmission and regulation of pain and may be a new target of neuropathic pain therapy.

Objective To assess the efficacy and safety of smoking intervention by anesthesiol-ogists in surgical patients.Methods A total of 182 male patients,aged 18-79 years,ASA grade Ⅰ-Ⅲ,scheduled for elective noncardiovascular and nonthoracic surgery,were assessed preoperatively. Patients were randomized to either the control group or the intervention group,n =91 each.The con-trol group did not receive specific smoking cessation intervention.The intervention group received brief counseling by the anesthesiologist,leaflets on smoking cessation,including pictorial health warning labels,smoking cessation clinic’s smokers’hot line and WeChat public number.Anesthesia methods,operation time,treatment time in PACU,the rate of smoking cessation at 30 days postop-eratively,perioperative complications and smoking status at 30 days postoperatively were recorded. Results One hundred and sixty-six patients were included in the analysis finally.There was no signif-icant difference between two groups in 30 days of follow-up postoperatively.Self-reported smoking re-duction in the postoperative 30 days the intervention group was significantly lower than that in the control group (36.9% vs.22.0%,P <0.05).For smokers,there was a relationship between the lev-el of eCO and the smoking cessation rate,it was 83.3% in the intervention group and 40.0% in the control group (P <0.05).There was no significant difference of overall rate of combined intraopera-tive and immediate postoperative complications between two groups.Conclusion Smoking cessation intervention launched by anesthesiologists promotes 30 days of abstinence postoperatively.

Ca2+signaling is fundamental for information process-ing in the peripheral nervous system,which regulates a variety of physiological activities.Ca2+signaling and calcium homeostasis are directly associated with neuropathology.Recently,studies on Ca2+signaling contribute to a deeper comprehension of the path-ogenesis of diabetic peripheral neuropathies,which provide a new research direction for the treatment of diabetic peripheralneuropathies.This review aims to highlight the relationship be-tween calcium signaling,sensory neurones and neuroglial cells in the context of diabetic peripheral neuropathies.

OBJECTIVE The aim of this study was to evaluate the outcomes of rehabilitation after cochlear implantation in children with malformed inner ear and compare them with a group of congenitally deaf children implantees with a normal inner ear.METHODS 21 children with inner ear malformation were retrospectively studied. The postoperative outcomes of these 21 cases were compared with that of 21 cases with normal inner ear structure. The assessment of all the children included the hearing levels, language ability , categories of auditory performance (CAP) and speech intelligibility rating (SIR) respectively before cochlear implantation, 6 months and 1 year after surgery. The data was analyzed using SPSS 17.0. RESULTS The results of rehabilitation in 9 children with Large Vestibular Aqueduct Syndrome and 6 cases with Mondini abnormality had no significant difference comparing with the control cases. The outcomes of 1case with severe Mondini abnormality and 5 cases with common cavity indicated significant worse than the control cases. CONCLUSION The effect of rehabilitation had no difference between the children with large vestibular aqueduct syndrome and the cases with normal inner structure after cochlear implantation, but was poorer in children with severe Mondini abnormality and common cavity. It was necessary to evaluate the degree of malformation of inner ear structure before cochlear implantation. The hearing abilities have improved quickly 6 months after cochlear implantation. The language abilities will need at least one year to get improved while the SIR need even more time. The development of language functions requires individualized rehabilitation guidance and integrated education.

Objective To observe the effect of heroin on EGF and IL-2 positive cells in the submandibular gland of rats. Methods Normal SD rats were divided into normal control group (NGC),saline control group (SCG)and heroin dependence group (HDG). The heroin dependent model of rats was established by subcutaneous injection of heroin, and submandibular glands were excised on the following days respectively: the 10th, 17th, 24th, 31th and 38th. Immunohistochemical SABC method, image analysis and cells calculation were used in the study. Results 1. As compared with those of the NCG, the number of EGF and IL-2 positive cells and the intensity of staining in SCG didn't change obviously. 2. During heroin dependence, the immunohistochemical staining showed that the number of EGF and IL-2 positive cells increased obviously(P

Bronchial asthma is one of the most common children health problems, with still increasing prevalence.Bronchial hyperresponsiveness is a characteristic feature of asthma,and its measurement may provide a useful adjunct in the diagnosis of asthma. Many children with asthma go into long-term clinical remission at adolescence, but bronchial hyperresponsiveness persists in approximately one half of these subjects, so implement the bronchial provocative tests in children with asthma remission may appears very important.

Aim To study the effect of oxymatrine (OMT)on protecting human umbilical vein endothelial cells (HUVECs)from toxicity induced by high glucose in vitro.Methods The HUVECs were cultured with medium containing different concentrations of glucose or OMT. The cells were randomly divided into 6 groups:5.5 mmol·L -1 control group(Control),22.2 mmol·L -1 high glucose (22.2 mmol·L -1 ),44.4 mmol·L -1 high glucose (44.4 mmol·L -1 ),control+OMT(control +OMT),22.2 mmol·L -1 high glu-cose +OMT(22.2 mmol·L -1 +OMT),44.4 mmol ·L -1 high glucose +OMT (44.4 mmol · L -1 +OMT).The protective effect of oxymatrine was as-sessed by MTS assays.The expression of A2B in HU-VECs was detected by Real-time quantitative PCR (qPCR)and Western Blot methods.Results The glucose was shown to have caused cytotoxicity in HU-VECs.Oxymatrine (3 μmol·L -1 )was found to have protected HUVECs from glucose toxicity effectively, and reduced the expression of A2B significantly.Con-clusion Oxymatrine can obviously protect HUVECs from cytotoxicity induced by high glucose and the effect is performed partly by decreasing A2B expression.

Objective To evaluate the levels of neutrophil gelatinase associated lipocalin (NGAL) in prediction of acute kidney injury (AKI) in children with burn. Methods Forty seven children with burn were selected in this study and thirty healthy children were enrolled as a control group. Levels of blood routine, urine routine, serum creatinine (Scr), serum NGAL (SNGAL), urine NGAL (UNGAL), blood urea nitrogen (BUN) and C-reactive protein (CRP) were measured. Receiver operating characteristic (ROC) curve were used to estimate the AKI diagnostic value of serum NGAL, urine NGAL and Scr. Results On the day of admission, serum NGAL and urine NGAL were significantly increased in patients with AKI , while Scr did not change significantly as compared with those in non-AKI patients and the healthy controls. In AKI group, serum NGAL and urine NGAL were positively correlated with WBC and CRP on the day of admission , and positively related with Scr on the seventh day. ROC analysis showed the AUC of serum NGAL, urine NGAL and Scr on admission were 0.737(95%CI: 0.653 ~ 0.779, P < 0.05), 0.772(95%CI: 0.632 ~ 0.793, P < 0.05), and 0.508(95%CI: 0.454~0.618, P < 0.05) respectively. The cut-off value of serum NGAL and urine NGAL were 318 μg/L (sensitivity of 72.8% and specificity of 81.6%) and 105 μg/L (sensitivity of 75.6% and specificity of 83.7%). Conclusions Elevation in levels of serum NGAL and urine NGAL occurs earlier than that in Scr level in children with burn. Both serum and urine NGAL level can be used as a biomarker for early prediction of AKI.

[Objective]To explore the dependability between heredity and hallux valgus.[Method]A total(1 491) cases of family heredity of hallux valgus patients were investigated,the ages of these patients,ages of onset,ages of aggravation,hallux valgus angles were analyzed statistically.[Result]Conclusive family medical history exists in 69.48% of the(1 491) hallux valgus patients.There was distinguished difference between the patients with family history and those without heredity background on visiting ages,ages of onset,ages of aggravation;but no any difference between these two groups of patients on hallux valgus angles.[Conclusion]Heredity factor is the main cause of hallux valgus.It can influence only the onset of hallux valgus,but not the severe degree of latter.The patients with family history are earlier than those without heredity background about visiting ages,ages of onset,ages of aggravation.
