Objective To construct a lentiviral vector-based short hairpin RNA (shRNA) targeting the gene encoding tryptophan-aspartate containing coat protein ( TACO) and to evaluate its inhibitory effect on the expression of TACO , and to further elucidate its effects on the phagocytosing and intracellular killing of My-cobacterium tuberculosis (M.tb) by macrophages and the possible mechanisms.Methods Three shRNA frag-ments targeting TACO gene and a scrambling control shRNA fragments were designed and cloned into the lentivi -ral vector pSicoR .The recombinant lentiviral vectors were identified by sequencing analysis and then packed in 293T cells.Real-time RT-PCR and Western blot assay were performed to evaluate the gene-silencing efficiency of the recombinant lentiviral vectors among RAW 264.7 cells transfected with the concentrated lentivirus .The most effective lentivirus was screened out to transfect the RAW 264.7 cells for 48 hours, followed by infection those cells with M.tb strains.The entry and intracellular survival of M .tb strains in RAW264.7 cells were de-termined by bacterial culture at indicated time points .The colocalization of M .tb and lysosomes was detected by immunofluorescence staining .The cyto-ID autophagy kit was used to detect the cellular autophagy and the auto-phagy-associated protein LC 3 was determined by Western blot assay .Results The recombinant lentiviral vec-tors were successfully constructed and confirmed by sequencing analysis .Decreased expression of TACO in RAW264 .7 cells was detected after transfecting the cells with the lentiviral vector-based shRNA vectors targeting TACO gene for 48 hours.The most effective lentivirus , LV-pSRT1, decreased the expression of TACO by 85.24%and 69.00%at the mRNA and protein levels, respectively.The bacterial loads in LV-pSRT1 trans-fected RAW264.7 cells were significantly decreased at the time point of 0 h after M.tb infection as compared with those in the control lentivirus treated cells (5.50×104 vs 8.1 ×104, P<0.05).Compared with the RAW264 .7 cells transfected with control lentivirus , the survival rate of intracellular M .tb strains in LV-pSRT1 transfected cells was significantly decreased at the time point of 48 h (134.54% vs 213.58%, P<0.05) and 72 h (148.18%vs 262.96%, P<0.05) considering the bacterial load at the time point of 0 h as the standard. The immunofluorescence staining demonstrated that the colocalization of M .tb strains with lysosomes was signifi-cantly enhanced in LV-pSRT1 transfected cells as compared with that in control lentivirus treated cells (75.67%vs 10.66%, P<0.05).Moreover, significantly enhanced autophagy and relative expression of LC 3Ⅱ protein were observed in RAW264.7 cells with TACO gene knockdown (16.20%vs 8.50%, P<0.05;0.51 vs 0.34, P<0.05).Conclusion The lentiviral vector-based shRNA targeting TACO gene could effectively knockdown the expression of TACO protein , decrease the entry and increase the intracellular killing of M .tb strains in mac-rophages.The enhanced intracellular killing of M .tb strains by macrophages was associated with the increased fusion of M.tb-containing phagosome and lysosome .

Objective:To explore the related risk factors of antepartum depression and anxiety,and to provide the theoretical support for early screening,clinical intervention and prevention of antepartum depression and anxiety.Methods:At the time of 28 weeks of prenatal examination,the Edinburgh Postnatal Depression Scale (EP-DS),Self-Rating Anxiety Scale (SAS)were used to survey 2112 pregnant women who were selected from Maternal and Child Health Hospital of Kunming City.Non conditional logistic regression analysis was used to explore the re-lated risk factors of prenatal depression and anxiety.Results:At the 28 weeks of pregnancy,the detection rate of de-pression symptoms and anxiety symptoms were 25.4% and 6.6%.Logistic regression analysis showed that the risk factors for perinatal depression symptoms were younger age (OR =0.80,95%CI:0.68 -0.94),not stick to work during pregnancy (OR =1.18,95%CI:1.02 -1.36),not satisfied with the living environment (OR =1.50,95%CI:1.23 -1.83),expectations for boys (OR =0.86,95%CI:0.77 -0.96),not only daughter (OR =1.37,95%CI:1.06 -1.76),unplanned pregnancy (OR =1.38,95%CI:1.10 -1.72).The risk factors for perinatal anxiety symp-toms were being not satisfied with the living environment (OR =1.64,95%CI:1.19 -2.26),not harmonious with her husband (OR =2.01,95%CI:1.20 -3.37),unplanned pregnancy (OR =1.50,95%CI:1.05 -2.14).Conclu-sion:It suggests that the pregnant women with younger age,less working during pregnancy,being not satisfied with the living environment,having more expectations for boys,being not only daughter,with unplanned pregnancy are more likely to suffer from antepartum depression;those being not satisfied with living environment,having harmoni-ous relation with her husband,and with unplanned pregnancy are more likely to suffer from antepartum anxiety.

Objective To evaluate the effect of spinal cord stimulation on the expression of neuronal nitric oxide synthase (nNOS) in the rats with diabetic neuropathic pain.Methods Forty-eight pathogen-free healthy male Sprague-Dawley rats,aged 2 nonths,weighing 250-300 g,were divided into 4 groups (n =12 each) using a random number table:control group (group C),diabetes mellitus group (group DM),sham operation group (group S) and spinal cord stimulation group (group SCS).Diabetic neuropathic pain was produced by intraperitoneal injection of 1％ streptozocin 75 mg/kg and confirmed by blood glucose level＞16.7 mmol/L on day 2 after streptozocin injection.Electrodes were implanted into the epidural space at 19 days after successful establishment of the model in S and SCS groups,and in addition spinal cord stimulation (frequency 50 Hz,pulse width 0.2 ms,intensity=2/3 of the lowest intensity) was performed for 30 min once a day at 26-28 days after successful establishment of the model in group SCS.The mechanical paw withdrawal threshold (MWT) was measured at 1 day before establishment of the model (T1) and 2,7,14 and 28 days after successful establishment of the model (T2-5).The rats were sacrificed after the last measurenent of MWT at T5,and the lumbar segment of the spinal cord was removed for determination of nitric oxide (NO) content and nNOS expression in spinal cord tissues.Results Compared with group C,the MWT was significantly decreased at T4.5,and the NO content and nNOS expression in the spinal cord were increased in DM,S and SCS groups (P＜0.05).Compared with group DM,the MWT was significantly increased at Ts,and the NO content and nNOS expression in the spinal cord were decreased in group SCS (P＜0.05).Conclusion The mechanism by which spinal cord stimulation allenuales diabetie neuropalhic pain is related to inhibiting nNOS expression and reducing NO production in rals.

Objective To observe the effect of spinal cord stimulation on expression of spinal GLT-1 and GLAST in rats with diabetic neuropatbic pain.Methods Forty-eight healthy male SD rats,only 2 months old,weighting 250-300 g,using the random number table method,were divided into four groups (n=12):the control group (group C),diabetes neuralgia group (group D),false stimulation group (group N)and spinal cord stimulation group (group S).The model of diabetes was induced by the pedtoneal injec-tion of streptozocin (STZ),electrodes were placed into the epidural space 1 9 days after injection of STZ in groups N and S,in addition,group S was performed 26-28 days after injection of STZ.Mechanical contrac-tion leg threshold (MWT)were determined one day before STZ injection,2 d,7 d,14 d and 28 d after STZ injection.The rats were sacrificed,the lumbar spinal cord tissue were obtained for determination of GLT-1 and GLAST expression in spinal cord tissues on 28 d after measurement of MWT.Results Compared with group C,MWT was decreased 14 d and 28 d after STZ injection,and expression levels of GLT-1 and GLAST mRNA were increased on 14 d and 28 d (P<0.05);Compared with before STZ injection,MWT of group D,group N and group S was decreased on 14 d and 28 d (P<0.05);Compared with group D, MWT was increased,and expression levels of GLT-1 and GLAST mRNA were increased in group S on 28 d after STZ injection (P<0.05 ).Conclusion The mechanism of spinal cord stimulation reducing rats diabetes neuralgia may be related to elevating the expression of GLT-1 and GLAST.

Objective: To understand parents attitudes towards adolescent sexual education in Baoshan City of Yunnan Province, and to explore the correlation between attitudes and their proactive behavior in adolescent sexual education, so as to provide reference for improving parents initiative in adolescent sexual health education. Methods: From November to December 2022, a stratified random cluster sampling method was used to select 7 389 parents of students from 35 primary, middle, and high schools in Baoshan City of Yunnan Province for a questionnaire survey on adolescent sexual health education in parents schools. Chi-square tests were conducted to compare the attitudes of parents towards sexual health education among different groups and their proactive behavior in providing sexual health education to their children. A multivariate Logistic regression model was used to analyze the correlation between parents attitudes towards sexual education and proactive sexual health education. Results: Totally 43.17% ( 3 190 ) of parents had a more open attitude towards sex education for their children, with parents of girls, parents of elementary school students, mothers, <30 years old, junior high school education, workers, service personnel, married, harmonious relationships with their children and democratic parents had a higher rate of actively providing sex education for their children ( χ 2=4.65, 401.92, 23.53 , 197.50, 38.18, 13.65, 6.54, 8.07, 32.17, 96.58, P <0.05). Parents with a more conservative attitude towards sex education and parents of boys were negatively correlated with parents actively providing adolescent sexual health education to their children ( OR =0.86, 0.38, P <0.05). Parents who were <30, 30-<40, 40-50 years old, individuals/businesses, married, divorced, had a good and decent relationship with their children were positively correlated with their parents proactive adolescent sexual health education for their children ( OR =1.50, 1.90, 1.37, 1.22, 1.60, 1.32, 1.94, 1.53, P <0.05). Conclusion A more open attitude towards adolescent sexual health education can serve as a predictive factor for proactive adolescent sexual health education. In order to increase the rate of family sexual health education, it is recommended to enhance parents awareness of their responsibility for their children s sexual health education, promote harmonious parent-child relationships between parents and children, and communicate with their children with an open attitude.

ObjectiveBy exploring the volatile components， polysaccharide composition and changes in the contents of five carbohydrate components of Polygonatum cyrtonema rhizoma before and after processing， and then the effect of yellow rice wine on the odour formation of P. cyrtonema rhizoma was investigated. MethodThe volatile components of P. cyrtonema rhizoma before and after processing were detected by headspace gas chromatography-mass spectrometry（HS-GC-MS）， and sample data were subjected to principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） using SIMCA 14.1， then the differences between these components of P. cyrtonema rhizoma before and after processing were screened according to the principle of variable importance in the projection（VIP） value>1. Crude carbohydrate components in raw and wine-processed P. cyrtonema rhizoma were subjected to oxime and silylation， the carbohydrate components were analyzed by gas chromatography-mass spectrometry（GC-MS/MS）， and the relative contents of various components were calculated by peak area normalization， then quantitative analysis of four carbohydrate components was also carried out. ResultA total of 23 volatile components were identified from the raw products and the wine-processed products， including 15 components in raw products and 20 components in wine-processed products. Among them， 2-methylbutyraldehyde and isovaleraldehyde had a sweet odor and their contents increased after processing， but the contents of hexanal and caproic acid decreased， new components such as 2-acetylfuran and 5-methylfuranal were produced after processing. PCA and OPLS-DA results showed that there were significant differences between raw products and the wine-processed products， a total of 13 differential compounds were screened out， of which 7 showed an upward trend in relative content and 6 showed a downward trend. A total of 7 carbohydrate components， including 5 monosaccharides and 2 disaccharides， were identified in raw products and the wine-processed products. The results of determination showed that the contents of fructose， glucose， mannose and sucrose in P. cyrtonema rhizoma increased after wine-processing， and their increases were 4.54， 1.51， 2.93， 3.66 times， respectively. ConclusionAfter processing， the increase of aromatic flavor of P. cyrtonema rhizoma may be related to the increase of the contents of aldehydes such as 2-methylbutyraldehyde and isovaleraldehyde， while the decrease of raw flavor may be related to the decrease of the contents of volatile components such as hexanal and hexanoic acid， the increase of sweet flavor may be related to the increase of the contents of monosaccharides and oligosaccharides such as fructose and sucrose.
