Objective To explore the effect of psychological nursing on anxiety and depression and quality of life of patients with multi drug resistant pulmonary tuberculosis.Methods 58 patients with multi -drug resistant pulmonary tuberculosis were randomly divided into observation group and control group,29 cases in each group.The control group received routine nursing care,the observation group received psychological nursing on the basis of the control group.Before and after psychological nursing intervention,the self rating anxiety scale(SAS)and depression self rating scale(SDS),health survey(SF -36)score were observed,and the clinical curative effect and compliance of the two groups were observed.Results After psychological nursing intervention,the SAS and SDS scores of the observation group[(36.83 ±7.61)points and (40.07 ±5.49)points]were significantly lower than the control group [(44.07 ±9.16)points and (43.90 ±7.91)points],the differences were statistically significant(t =3.27,2.14,all P <0.05).The SF -36 scores showed that after psychological nursing intervention,the physiological function(PF), physiological functions(RP),general health(GH),vitality(VT),social function(SF),role emotional(RE),mental health(MH),the seven dimensions scores of the observation group were significantly higher than those in the control group,the differences were statistically significant(t =7.18,10.22,8.85,12.71,12.04,9.68,4.79,all P <0.05). The compliance of the observation group was 93.10%,which of the control group was 72.41%,the difference was significant(χ2 =4.35,P <0.05).The total effective rate of the observation group was 86.21%,which of the control group was 62.07%,the difference was statistically significant(χ2 =4.41,P <0.05).Conclusion The psychological nursing intervention can improve the anxiety and depression of patients with multi -drug resistant tuberculosis, improve the quality of life of patients,improve the treatment compliance of patients,and improve the clinical efficacy.

Objective To develop a nested PCR for the detection of early syphilis and genotyping of Treponema pallidum (TP), and to investigate the distribution of genotypes of TP in Guangzhou. Methods Specimens were consecutively collected from genital ulcers of patients with suspected chancre during 2002-2004, and were detected by dark-field microscopy and nested PCR. The acidic repeat protein (arp) gene and the T. pallidum repeat (tpr) gene family were amplified with the positive specimens above. The number of repeats presented in the arp gene and the restriction fragment length polymorphism by Mse I in the tpr gene were analyzed by electrophoresis. The strains were genotyped according to Pillay's criteria. Results Out of 62 patients with suspected chancre, 33 cases (53.2%) were positive by dark-field microscopy and 54 cases (87.1%) by nested PCR. Of 47 TP-positive specimens genotyped by arp gene, 36 (76.6%) were type 14, while of 49 cases genotyped by tpr gene 39 (79.6%) were type d. By combining genotypes of arp and tpr genes, 7 genotypes were found, including 14d (31, 66.0%), 13d (5, 10.6%), 14b (4, 8.5%), 12b (3, 6.4%), 12d (2, 4.3%), 15d(l, 2.2%) and 14i (1, 2.2%). Conclusions Nested PCR shows a high sensitivity in early detection of TP. Genotype 14d seems the predominant type of TP in Guangzhou.

Objective The aim of this study was to explore the inhibitory effect of alcohol extracts of Narcissus bulb on melanogenesis in zebrafish embryos.Methods Zebrafish embryos were exposed to different concentrations of alcohol extracts of Narcissus (0, 50, 100, 200, and 500 μg/mL), and then the formation of melanin was observed.Furthermore, we measured the enzyme activity of tyrosinase (TYR), which plays a pivotal role in melanogenesis.Meanwhile, the spatial and temporal pattern of melanin-specific marker genes were detected.Arbutin (Ar) was used as a positive control in all these experiments.Results The treatment of alcohol extracts of Narcissus bulb inhibited melanogenesis in the zebrafish embryos in a dose-dependent manner.Furthermore, the mRNA expression levels of melanin-related genes such as tyrosinase (TYR), silver (SILV) and Mitfa were significantly reduced after treatment with different concentrations of Narcissus extracts by in-situ and semi-quantitative PCR.Finally, the enzyme activity of tyrosinase was also gradually decreased with increasing concentrations of the alcohol extracts.Conclusions Narcissus alcohol extracts can effectively inhibit the production of melanin in zebrafish embryos.This study provides potential evidence and approaches for the screening of natural whitening compounds using zebrafish models.

Objective To investigate the diagnostic correlation and sensitivity of amplitude integrated electroencephalogram (aEEG),brainstem auditory evoked potential (BAEP) and cranial magnetic resonance imaging (MRI) for acute bilirubin encephalopathy (ABE) in the newborn.Method Term and near-term neonates (gestational age ≥ 35 weeks) with hyperbilirubinemia (the level of bilirubin over than 95th percentile) of high and intermediate risk group admitted in the neonatal ward of Guangxi Maternal and Child Health Care Hospital from Jan 2014 to Dec 2015 were recruited retrospectively.The infants were assigned to ABE group and non-ABE group according to the diagnostic criteria of ABE.The clinical data of the newborns were collected and the diagnostic correlation between clinical diagnosis and aEEG,BAEP and cranial MRI were analyzed.The receiver operating characteristic (ROC) curve was adopted to assess the diagnostic efficiency of the peak level of serum bilirubin,aEEG,BAEP and cranial MRI on the early diagnosis of ABE.Result A total of 152 newborns with hyperbilirubinemia were recruited,including 33 cases in the ABE group and 119 cases in non-ABE group.(1) The results of aEEG and MRI were marginally positively correlated with clinical diagnosis of ABE (aEEG:r =0.487,P ＜ 0.001;MRI:r =0.220,P=0.018),while the results of BAEP were closely related to the clinical diagnosis of ABE (r =0.593,P ＜ 0.001);(2) The results of BAEP and MRI on the diagnosis of ABE were positively correlated with those of aEEG (BAEP:r =0.424,P ＜ 0.001;MRI:r =0.307,P ＜ 0.001).(3) The area under the ROC curves for predicting the onset of ABE were 0.899 for the peak level of serum bilirubin,0.767 for BAEP,0.738 for aEEG and 0.590 for MRI.Conclusion There was the correlation on the diagnosis of ABE among the methods of aEEG,BAEP and MRI.The combined diagnosis of the three methods could play a complementary role.The aEEG contributed to the early diagnosis of ABE with high sensitivity.

Objective: To investigate the characteristics of neuropsychological factors in patients with persistent postural-perceptual dizziness(PPPD) and provide the basis for the psychosomatic comprehensive treatment. Methods: Cartel Personality Test (16PF), Symptom Checklist 90 (SCL-90), HAMA, HDMD, SAS and SDS were used to evaluate personality and mental state in patients with PPPD(PPPD group, n=65) and control group(n=63). Dizziness handicap inventory(DHI) was used to evaluate the degree of vertigo.The correlation analysis was carried out between the DHI scores and 16-PF, SCL-90 factor scores. Results: (1)16PF factor scores: the factor scores of assertiveness(8.50±1.84), excitability (6.59±1.73), boldness (7.46±1.78), sensitivity (7.25±1.79), doubtfulness (6.55±1.74), fantasy(6.20±1.60), anxiety(7.67±1.61) and tension(6.81±1.67)in PPPD group were higher than those in the control group, and the differences were statistically significant (all P<0.05). The gregariousness (4.38±1.65), intelligence (4.51±1.67), stability (3.51±1.75), independence (4.39±1.56) and self-discipline (4.70±1.82) factor scores in PPPD group were lower than those in the control group, and the differences were statistically significant (all P<0.05). (2)SCL-90 factor scores: the factor scores of somatization(1.62±0.40), anxiety (1.64±0.56), interpersonal sensitivity (1.79±0.42), terrifying(1.71±0.53), total points(150.77±21.60), total average score (1.62±0.51) in PPPD group were higher than those in control group (all P<0.05). There were no differences in obsessive-compulsive (1.50±0.55), depression (1.45±0.44), hostility (1.69±0.60), paranoia (1.76±0.53), somatization (1.42±0.49) and psychotic (1.29±0.35) between PPPD group and the control group (all P>0.05). (3)The factor scores of HAMA(9.08±1.77) and SAS(37.88±2.96)in patients with PPPD were higher than that in the control group, and the differences were statistically significant (all P<0.05). There was no significant difference in HAMD (6.19±2.82) and SDS (36.36±4.71) scores between PPPD group and control group (all P>0.05). (4)The DHI scores were positively correlated with assertiveness, sensitivity, tension and doubtfulness factors of 16PF.The DHI scores were positively correlated with somatization, interpersonal sensitivity, anxiety and terrifying factors of SCL-90. Conclusion Patients with persistent postural-perceptual dizziness suffer from personality changes, mental disorders and anxiety disorder.

ObjectiveTo discuss the effects of targeted nursing intervention on pregnancy outcome and neonatal weight in patients with gestational diabetes mellitus (GDM). MethodsTotally 108 GDM patients treated in our hospital from July 2017 to February 2019 were selected and divided into intervention (n=54) and control (n=54) groups according to the random number table. Patients in the control group received conventional nursing care, while patients in the intervention group received targeted care on this basis. Patient＇s blood glucose level, pregnancy outcome, neonatal weight and satisfaction with nursing before and after nursing care were compared between the two groups. ResultsThere was no statistically significant difference in blood glucose levels between the two groups before nursing intervention (P＞0.05). Fasting blood glucose, 2 h postprandial blood glucose and glycosylated hemoglobin levels were lower after nursing intervention in both groups. The levels of the intervention group were even lower than those of the control group, and there were statistically significant differences between the two groups (P＜ 0.05). The incidence of malignant pregnancy outcome and neonatal complications of the intervention group were lower than those of the control group after nursing intervention, and patient＇s satisfaction with nursing was higher in the intervention group than in the control group, and there were statistically significant differences between the two groups (P＜ 0.05). ConclusionsTargeted nursing intervention can effectively reduce blood glucose levels of GDM patients and the incidence rate of adverse maternal and neonatal outcome, and improve patient＇s satisfaction, which is worth promoting in clinical practice.

Objective To explore the effect of Lee-Silverman voice treatment (LSVT) on language re-habilitation of dysarthria in Parkinson's disease (PD).Methods A total of 84 patients with PD dysarthria ad-mitted to our hospital from February 2019 to February 2022 were selected as the research objects.According to the random number table method,they were divided into observation group and control group,with 42 cases in each group.The control group received routine speech rehabilitation training,and the observation group re-ceived LSVT for four weeks.The scores of Western Aphasia Battery (WAB) and Aphasia Quotient (AQ) be-fore and after intervention were compared between the two groups,and the differences of electroglottographic parameters such as jitter,F0,shimmer,normalized noise energy (NNE) and harmonic noise ratio (HNR) were compared between the two groups.Results Before intervention,there was no significant difference in WAB scores (listening comprehension,repetition,spontaneous speech,naming) and AQ scores between the two groups (P>0.05).After intervention,the above scores of the two groups were significantly improved,and the observation group was higher than the control group,the difference was statistically significant (P<0.05). Before intervention,the jitter,F0,shimmer,NNE,HNR of vowels "a""i""u" in the two groups were not sta-tistically significant (P>0.05).After intervention,the above-mentioned electroglottic parameters of the two groups were significantly improved.The jitter and NNE of vowels "a""i""u" in the observation group were lower than those in the control group,and the HNR was higher than that in the control group,the differences were statistically significant (P<0.05).Conclusion LSVT can improve the electroglottographic parameters and speech function of patients with PD dysarthria,and the language rehabilitation effect of PD dysarthria is obvious.
