Objective To investigate the effect of open nursing management on hospital rehabilitation of patients with schizophrenia.MethodsThe outcome of group A,which included 113 patients in open nursing management,and group B,which included 141 patients in close nursing management at the same time,were evaluated with the Brief Psychiatric Rating Scale(BPRS)and the Nurses' Observation Scale for Impatient Evaluation(NOSIE),etc.ResultsThe difference between the two groups in such as the time of symptoms improved,drugs administration,effective rates were not significant(P>0.05).The compliance of medicine,social capability and personal sanitation of group A were improved compared with those in group B(P<0.05),while the time stay in hospital obviously shortened(P<0.01).ConclusionThe open nursing management is helpful to improve the rehabilitation and shorten the time stay in hospital of patients with schizophrenia.

Objective To investigate the effect of electro-acupuncture on behavior alterations,the expression of amyloid precursor protein(APP),amyloid β-protein(Aβ) proteins and neuroapoptosis in the cerebral cortex in the APPswe/PS1dE9 double transgenic mice with Alzheimer's disease (AD) induced by isoflurane.Methods Sixmonth-old AD mice and wild-type mice at the same age were randomly divided into wile-type control group,AD group,isoflurane group,electro-acupuncture group (N =8).The mice were given pretreatment with electro-acupuncture at Baihui(GV20) acupoint and Yongquan(KI 1) acupoint once a day for 3 successive days,15 min each time.And then the mice in electro-acupuncture group and isoflurane group were exposed to a box full of 1.2％ isoflurane for 4 hours.Morris water maze was used to test the learning and memory abilities of the mice,Western blotting method was used to detect the expression of APP-C83,APP-C99 and Aβ,and terminal deoxynucleotidyl transferase(TdT)-mediated dUTP nick end labeling(TUNEL) was used to detect neuroapoptosis in the cerebral cortex.Results The escape latency of AD group was longer than that of wild-type mice group(P＜0.05),and the latency of isoflurane group was longer than that of AD group (P ＜ 0.05),while the latency of electro-acupuncture group was shorter than that of isoflurane group(P ＜ 0.05).The percentage of retention time in the target quadrant and the times for crossing the target quadrant in isoflurane group were lower than those of AD group (P ＜ 0.05),but were higher in electro-acupuncture group than those in isoflurane group (P ＜ 0.05).APPC83 expression level in isoflurane group was significantly lower than that in AD group (P ＜ 0.05),while APP-C83 expression level in electro-acupuncture group was higher than that in isoflurane group (P ＜ 0.05).APP-C99 expression level in isoflurane group was significantly higher than that in AD group (P ＜ 0.05),and APP-C99 expression level in electro-acupuncture group was lower than that in isoflurane group (P ＜ 0.05).The cortical apoptosis index in isoflurane group was significantly higher than that in AD group (P ＜ 0.05),and the cortical apoptosis index in electro-acupuncture group was lower than that in isoflurane group (P ＜ 0.05).The expression level of Aβ in AD group,isoflurane group and electro-acupuncture group was significantly higher than wild-type control group (P ＜ 0.05).Conclusion Electro-acupuncture can relieve the AD-like neurotoxicity induced by isoflurane and inhibit the decline of learning and memory abilities of AD mice,and the mechanism is probably related with suppressing the overexpression of APP-C99 and reducing the production and accumulation of Aβ,thereby alleviating the neuroapoptosis.

Objective:To analyze the sleep quality before treatment and related risk factors of sleep disorder in patients with nasopharyngeal carcinoma (NPC). Methods: Totally 143 patients first diagnosed as nasopharyngeal carcinoma were selected [ average age (43 ± 10) years, 100 males and 43 females] in a NPC ward of one hospital, the Chinese version of Pittsburgh Sleep Quality Index (PSQI, total score ＞ 5 diagnosed as sleep disorder) was used to investigate the sleep quality before treatment, and the logistic regression analysis was used to analyze related factors of the sleep disorder before treatment Results: The rate of sleep disorder was 50.3％. The logistic regression analysis showed that age was a risk factor of sleep disorder before treatment in patients with NPC (OR = 1.04, 95％ CI: 1.01-1.08), while gender, culture degree, clinical stage, body mass index were not correlated with sleep disorder (Ps＞0.05). Conclusion: It suggests that patients with NPC may have a higher incidence of sleep disorder before treatment, and older patients may be more prone to pre-treatment sleep disorder.

Objective To analyze the difference of serum levels of anti-Mullenan hormone (AMH) in chil-dren with different ages and different types of cryptorchidism,and to explore its role in the evaluation of tes-ticular development.Methods 60 children with simple cryptorchidism were selected as case group and 52 healthy children were selected as control group.The levels of serum AMH in two groups of children were measured and the differences were compared.Results (1)The level of AMH in the case group was lower than that in control group (P < 0.05),and there was no statistical significance between two subgroups of >6 to 11 years old children with cryptorchidism and healthy children (P>0.05).(2)The level of AMH in bi-lateral cryptorchidism group was lower than that in unilateral cryptorchidism group (P<0.05),and there was no significant difference between two subgroups of >6 to 11 years old children with bilateral cryptorchidism and unilateral cryptorchidism (P>0.05).(3)The level of AMH in the high level cryptorchidism group was lower than that of the low level cryptorchidism group (P<0.05),and there was no statistical difference be-tween between two subgroups of 3~11 year old children with cryptorchidism and low level cryptorchidism (P>0.05).(4)AMH level was negatively correlated with age,and positively correlated with testicular devel-opment.Conclusion AMH can be used as an important indicator of testicular development in children with cryptorchidism.

Objective:To analyze the detection rate of hyperuricemia (HUA) and the distribution of serum uric acid (SUA) levels by multiple correlation analysis in middle-aged and elderly population receiving health examination.Methods:In this cross-sectional study, the study object were 25 587 middle-aged and elderly people who receiving health examination in Nanfang Hospital from January to December in 2014. According to the latest diagnostic criteria, the population was divided into HUA and non-HUA groups. Furthermore, the subjects were divided into 4 groups with the level of SUA (Q 1: SUA<313 μmol/L, Q 2:313 μmol/L≤SUA<375 μmol/L, Q 3:375 μmol/L≤SUA<440 μmol/L, Q 4: SUA≥440 μmol/L). According to the data types, two independent sample t test, Mann-Whitney U test, Chi-square test and multiple correspondence analysis were used for statistical analysis. Results:The mean age of the study subjects was (54.78±8.80) years with 16 570 males (64.8%) and 9 017 females (35.2%). The overall detection rate of HUA was 31.5%, and it was higher in men (43.1%) than in women (10.1%). The body mass index(BMI), systolic blood pressure, diastolic blood pressure, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and fasting blood glucose (FBG) in the HUA group were all higher than those in the non-HUA group (all P<0.001); and high-density lipoprotein cholesterol (HDL-C) was lower than that in the non-HUA group( P<0.001). In multiple correspondence analysis, Cronbach′s α coefficients of the first dimension and the second dimension was 0.608 and 0.237, respectively. Further analysis was performed stratified by gender, it indicated that 45-<55 years old male and overweight were closely associated with the Q 3 group, fatty liver and hyperlipidemia were closely associated with Q 4 group; the 55-<65 years old female, hyperlipidemia, fatty liver and obesity were closely associated with the Q 3 group, while hyperglycemia and hypertension were closely associated with the Q 4 group. Conclusion:The detection rate of HUA in middle-aged and elderly population receiving health examination was high, and the detection rate of HUA in male was higher than that in female. SUA levels are higher in middle-aged and elderly men who have fatty liver and hyperlipidemia. While SUA levels are higher in middle-aged and elderly women who have hyperglycemia and hypertension.

Objective To discuss the extent and characteristics of symptoms and symptom distress, and find the individualized management for patients undergoing bladder perfusion chemotherapy after transurethral bladder resection of bladder tumor. Methods The general information questionnaire, M. D. Anderson Symptom Inventory ( MDASI) and additional entries were used to investigate 84 patients undergoing bladder perfusion chemotherapy after transurethral bladder resection of bladder tumor. After individualized treatment, scores of symptoms were observed. Results Symptom score of patients in this group was (3. 12 ± 1. 02), which was at the mild level. Symptoms subscale score entries sorted successively as poor appetite, fatigue, disturbed sleep, nausea, and vomiting. Symptom distress score was (2. 85 ± 2. 02), which was at the mild level. Distress subscale score in the order of entries were work, mood and general activity, enjoyment of life, walking and relationship. Added entries score in the order were burning sensation in the bladder, bladder irritation and gastrointestinal reactions. Scores of some symptoms were significantly lower than before ( P < 0. 05 ). Conclusions Symptom distress is prevalent in patients undergoing bladder perfusion chemotherapy after transurethral bladder resection of bladder tumor, prompting that the intervention should be individualized according to the patient′s symptom distress features to alleviate their symptoms distress.

Objective To observe the effect of electroacupuncture on corneal Toll-like receptor 4(TLR4)-mediated inflammatory signaling pathway in diabetic dry eye rats and to explore the mechanism of electroacupuncture in the treat-ment of diabetic dry eye.Methods A type 2 diabetic rat model was established in 32 healthy male Sprague-Dawley(SD)rats by intraperitoneal injection of streptozotocin(30 mg·kg-1)for 12 weeks after feeding with high-sugar and high-fat di-et for 4 weeks.Twenty-five successfully modeled diabetic dry eye rats were randomly divided into the model group(non-in-tervention),electroacupuncture group(the"Jingming","Cuanzhu","Sizhukong","Taiyang"and"Tongziliao"acupoints were treated with acupuncture,and then"Cuanzhu"and"Tongzilao"acupoints were treated with electroacupuncture,15 min for each time,once a day),sham acupuncture group(blunt-tip needle pricking was performed at the same acupoints as the electroacupuncture group),and fluorometholone group(1 g·L-1fluorometholone eye drops were used in both eyes at 8 o'clock,13 o'clock,and 18 o'clock,1 drop each time),with 6 rats in each group,lasting for 2 weeks.Another 6 healthy male SD rats were selected as a blank group.Random blood glucose,tear film breakup time(BUT),tear secre-tion,corneal fluorescein staining(FL)score,and corneal touch threshold(CTT)of rats in each group were detected be-fore modeling,after modeling,and after the intervention.Hematoxylin and Eosin(HE)staining was performed to observe the corneal morphologic changes in each group.Immunofluorescence histochemical staining was adopted to detect the cor-neal TLR4-positive expression in each group.The TLR4,phosphorylated nuclear factor-kappa P65(P-NF-KB P65),inter-leukin(IL)-1β,and IL-18 expression levels in the cornea were detected by Western blot.Results After modeling,com-pared with the blank group,BUT,tear secretion and CTT decreased and FL increased in all experimental groups,and the differences were statistically significant(all P＜0.01).After the intervention,compared with the model group,FL de-creased,and BUT,tear secretion and CTT increased in the electroacupuncture group,and the differences were statistically significant(all P＜0.05).Corneal HE staining showed that after the intervention,the corneal surface of rats in the model group and sham acupuncture group was not smooth,and the corneal epithelial cells were thickened and disorganized;the corneal surface of rats in the electroacupuncture group and fluorometholone group was smooth,and the corneal epithelial cells were arranged neatly.After the intervention,compared with the blank group,the corneal TLR4 expression of rats in all other groups was elevated,and the differences were statistically significant(all P＜0.05);compared with the model group,the corneal TLR4 expression of rats in the electroacupuncture group and fluorometholone group was reduced(both P＜0.01).Compared with the blank group,corneal TLR4,P-NF-κBP65,IL-1β and IL-18 protein expressions increased in the model group and sham acupuncture group(all P＜0.05);compared with the model group,these expressions decreased in the electroacupuncture group and the fluorometholone group(all P＜0.05).Conclusion Electroacupuncture can im-prove the ocular surface signs and inhibit the expressions of TLR4,P-NF-κB P65,IL-1 β,and IL-18 in the cornea of type 2 diabetic dry eye rats,and its mechanism of action may be related to the regulation of TLR4-mediated inflammatory signaling pathway,which inhibits ocular surface inflammation in diabetic dry eye rats.

Objective To compare the efficiency of nomogram and different machine learning algo-rithms for constructing the dental caries predictive models for middle-aged and elderly people.Methods The multi-stage stratified random sampling method was used to select 510 middle-aged and elderly people from Nanning City,Guigang City and Chongzuo City as the research subjects for conducting the questionnaire sur-vey and oral cavity examination.The univariate analysis and Lasso regression were used to screen the related variables,and the multivariate logistic regression analysis was used to determine the final independent influen-cing factors.Based on the salient features,the nomogram predictive model was established,and the seven ma-chine learning algorithms,including linear discriminant analysis (LDA),partial least squares (PLS),range Doppler algorithm (RDA),generalized linear models (GLM),random forest (RF),support vector machine (SVM) kernel function (SVM-Radial),and SVM linear kernel function (SVM-Linear),were used to construct the seven kinds of dental caries risk predictive models.The area under the receiver operating characteristic (ROC) curve (AUC) was adopted to evaluate the predictive performance of various models and the predictive performance of models constructed using different variable screening methods.Results The detection rate of dental caries in middle-aged and elderly people was 71.18％.After feature screening,the five predictive factors were ultimately retained,which were the age (OR=0.945,95％CI:0.917-0.973),brushing frequency (OR=0.688,95％CI:0.475-0.997),whether having teeth cleaning in the past one year (OR=0.303,95％CI:0.103-0.890),number of remaining teeth (OR=1.062,95％CI:1.038-1.087) and oral health assess-ment tool (OHAT) score (OR=1.363,95％CI:1.234-1.505).The results of comparison of various models showed that the predictive model constructed by the RF algorithm performed the best,the median of AUC was 0.747,followed by the nomogram,and the median of AUC was 0.733.The median of AUCs in the predic-tion model constructed by single factor+Lasso+multivariate logistic (Lasso+logistic) screening independent variables were higher than those constructed by RF algorithm screening independent variables.ConclusionBased on Lasso+logistic screening variables,RF provide more reliable predictive efficiency in predicting dental caries in middle-aged and elderly people than nomogram and the other machine learning algorithms.
