Objective To investigate the prevalence rates of sleep disorders and the correlatives in the elderly from Taiyuan city.Methods All of the 3173 elderly (aged 60 years to 100 years) in Taiyuan city were investigated at home through questionnaires,regarding their sleep condition.Subjects with sleep disorders were then screened through questionnaires and reexamined/diagnosed by special doctors.Results (1) Among the 3173 elderly,2132 subjects complained of having sleep disorders.The total prevalence of sleep disorders was 67.2%.The prevalence rates of chronic insomnia,multi-dreams,habitual snoring and daytime drowsiness were 39.65%,38.58%,26.66% and 34.32% respectively.(2)In the male elderly,the prevalence rates of being awaken early,having more urination at night,daytime drowsiness,sleep-respiratory disturbance and indiscriminate sleep rhythm increased with age(P＜0.01).However,in the female elderly,the prevalence rates of being awaken early,having daytime drowsiness and indiscriminate sleep rhythm also had a tendency of increase (P＜0.01).(3) Living alone,emotional disorder,pain and nocturia (P＜0.01) were the risk factors of chronic insomnia in the male elderly while living alone,numbness/pruritus(P＜0.01),emotional disorder (P＜0.05),were the risk factors of chronic insomnia in the female elderly.Conclusion The prevalence rates of some sleep disturbances in the elderly in Taiyuan city were generally correspondent with prevalence rates reported elsewhere that called for more attention be paid to the effect of mood disturbance and diseases related to sleep condition among the eldexly.

Objective: To explore the points selection pattern of acupuncture for sleep apnea syndromes by data mining technique. Methods: Clinical literature about acupuncture therapy for sleep apnea syndromes was derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed and Science Direct between the time that databases were created and March 25th,2017. Relevant excel database was established and descriptive studies and association rules were analyzed. Results: The most frequently used point was Lianquan (CV 23) and the most frequently used meridian was the Stomach Meridian. The analysis of association rules showed that the clinical choice of acupuncture points was highly correlated, among which the combination of the highest degree of confidence and the highest degree of support was Shenmen (HT 7) and Sishencong (EX-HN 1); Lieque (LU 7), lianquan (CV 23) and Zhaohai (KI 6). Conclusion: Acupuncture treatment of sleep apnea syndromes has specific selection rules of points, providing certain references for clinical and scientific research.

Abstract: Objective　To investigate the diagnostic efficacy of rifampin-resistant real-time fluorescent quantitative nucleic acid amplification detection technology (GeneXpert MTB/RIF) in bronchoalveolar lavage fluid (BALF) combined with peripheral blood tuberculosis infection T cell spot test (T-SPOT) and tuberculosis antibody (TB-Ab) in smear-negative pulmonary tuberculosis. Methods　The clinical data of 114 cases of clinically diagnosed smear-negative pulmonary tuberculosis, 80 cases of non-tuberculous pulmonary diseases and 22 cases of smear-positive pulmonary tuberculosis in our hospital from January 2019 to January 2021 were retrospectively analyzed. The detection results of peripheral blood T-SPOT, TB-Ab and BALF GeneXpert in the three groups were analyzed. The sensitivity, specificity, negative predictive value, positive predictive value, false negative rate, false positive rate and Youden index of the three detection methods were compared. The differences in the positive detection rate of smear-negative pulmonary tuberculosis between the separate detection and the combined detection of the three methods were compared. The receiver operating characteristic curve (ROC) was performed to calculate the area under the curve (AUC). Results　The sensitivity of BALF GeneXpert and peripheral blood T-SPOT and TB-Ab was 66.91%, 80.88% and 90.44%, respectively. The specificity was 98.75%, 73.75% and 41.25%, respectively; the diagnostic coincidence rates were 78.70%, 78.24% and 72.22%, respectively, which were higher than 70.00%. In the smear-negative pulmonary tuberculosis group, the positive detection rates of these three methods in the smear-negative pulmonary tuberculosis group were 63.15%, 79.82% and 90.35%, respectively, and the differences were statistically significant compared with those in the non-tuberculosis pulmonary disease group (all P<0.01). The positive detection rate of the three combined methods in the smear-negative pulmonary tuberculosis group was 96.49 %, which was significantly higher than that of TB-GeneXpert method and T-SPOT, and the differences were statistically significant (χ2=37.283, P<0.01; χ2=13.612, P<0.01); the Youden index of combined detection was significantly higher than that of single detection, and the AUC of combined detection was 0.977, which was significantly higher than that of single detection. Conclusion　BALF GeneXpert combined with peripheral blood T-SPOT and TB-Ab can significantly improve the diagnostic rate of bacterial-negative pulmonary tuberculosis, providing a strong basis for guiding clinical treatment.

OBJECTIVEQuantitative determination was made of ethyl-p-hydroxybenzoate in Dracaena cochinchinensis extracted with two technologies.

METHODThe sample was resolved with methanol and isolated by TLC, purged with methanol. Tge sample solution was chroma to graphed on a C18 column with acetonitrile-1% acetic acid (31:69) as mobile phase, detecting at 257 nm and content was calculated with external standard method.

OBJECTIVETo isolate and identify nisin resistance determinant (NSR) gene from Lactococcus lactis.

METHODSThe Lactococcus lactis strains harboring NSR gene were isolated from different milk samples by selective culture supplemented with nisin and confirmed by PCR detection of 16S rRNA. Nisin resistance determinant gene was determined by PCR amplification, enzyme digestion and sequencing.

RESULTSThirty nisin-resistant Lactococcus lactis strains from fresh milk samples were obtained. Three of these strains contained NSR gene of about 1000 bp as determined by agarose gel electrophoresis and further confirmed by enzyme digestion and sequence analysis. The NSR gene was located on the plasmid of Lactococcus lactis.

CONCLUSIONComplete NSR gene, located on the bacterial plasmid, has been successfully isolated from nisin-resistant Lactococcus lactis strains from fresh milk.

OBJECTIVETo establish discriminant functions of diarrhea-predominant irritable bowel syndrome (IBS-D) by studying it from quantitative diagnosis angle, hoping to reduce interference of subjective factors in diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

METHODSA Chinese medical clinical epidemiological survey was carried out in 439 IBS-D patients using Clinical Information Collection Table of IBS. Initial syndromes were obtained by cluster analysis. They were analyzed using step-by-step discrimination by taking information of four Chinese medical diagnostic methods and serum brain-gut peptides (BGP) as variables.

RESULTSClustering results were Gan stagnation Pi deficiency syndrome (GSPDS), Pi-Wei weakness syndrome (PWWS), Gan stagnation qi stasis syndrome (GSQSS), Pi-Shen yang deficiency syndrome (PSYDS), Pi-Wei damp-heat syndrome (PWDHS), cold-damp disturbing Pi syndrome (CDDPS). Of them, GSPDS was mostly often seen with effective percentage of 34. 2%, while CDDPS was the least often seen with effective percentage of 5.5%. A total of 5 discriminant functions for GSPDS, PWWS, GSQSS, PSYDS, and PWDHS were obtained by step-by-step dis- crimination method. The retrospective misjudgment rate was 4.1% (16/390), while the cross-validation misjudgment rate was 15.4% (60/390).

CONCLUSIONThe establishment of discriminant functions is of value in objectively diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

Objective To identify and monitor potential risk areas of schistosomiasis in Dongting Lake area. Methods With remote sensing (RS)and geographic information system(GIS) technology, potential risk areas of schistosomiasis in Dongting Lake area were extracted by using spectral characteristics and environmental factors. Based on epidemiological data and land use data, the regional epidemic index and environmental susceptibility index were fused with potential epidemic risk areas in the grid system of Dongting Lake area to form the epidemic risk surveillance map of schistosomiasis in Dongting Lake area from 2006 to 2016. Results From 2006 to 2016, the high risk areas of schistosomiasis epidemic in Dongting Lake area were concentrated in the central and Northern lakeside areas of Changde City (Annual average epidemic index R-=0.330 5, Regional average susceptibility index Y-=2.458 2), the sensitive land types were Lake area (Sensitivity coefficient β=1.236 6), the surrounding area of Datong Lake in Nanxian and Northern Yuanjiang City (R-=0.426 0, Y-=0.836 8), paddy field area (β=0.202 1) and other construction land (β=0.308 0). The extremely high risk areas were concentrated in some lake-facing areas in Jinshi (R-=0.449 1, Y-=3.917 0) and the sensitive land type is woodland(β=1.234 5). The risk of river basin from high to low was respectively the Lishui River, the Yuanjiang River, the Zijiang River and the Xiangjiang River. Conclusions The high-risk and extremely high-risk areas should be the focus of future epidemic control. The snail control and environmental renovation of epidemic-sensitive areas such as sparse woodland, grassland with high coverage, reservoir pits and ponds should be done well in Dongting Lake area.
