Objective:Based on the health ecological model, this paper systematically explores the influencing factors of mild cognitive impairment among the elderly herders in Nanshan pastoral area of Xinjiang, and provides the basis for local medical institutions to formulate prevention and control strategies for mild cognitive impairment among the elderly herders.Methods:A total of 1 145 valid questionnaires were collected, all of them were permanent herdsmen aged over 60 years in Nanshan pastoral area of Xinjiang were selected from June 2022 to February 2023 by stratified cluster random sampling method in a cross-sectional survey. Under the guidance of health ecological model, the research variables were included from five dimensions: physiology, psychology, behavioral lifestyle, social network and medical and health environment, and questionnaires were conducted. SPSS 23.0 was used for chi-square test and binary Logistic regression to analyze the influencing factors of mild cognitive impairment in elderly herders.Results:There were 564 males and 581 females with age of (70.84 ± 5.69) years old in the study. The prevalence rate of mild cognitive impairment among elderly herdsmen in Nanshan pastoral area of Xinjiang was 36.1%(413/1 145). Binary Logistic regression analysis showed that: personal monthly income (1 000-2 999 yuan)( OR = 0.583, 95% CI 0.366 - 0.926, P<0.05), education level (junior high school and above)( OR = 0.479, 95% CI 0.315 - 0.728, P<0.01) were the protective factors for mild cognitive impairment among the elderly herdsmen in Nanshan pastoral area. Hypertension ( OR = 1.842, 95% CI 1.256 - 2.702, P<0.01), dyslipidemia ( OR = 1.449, 95% CI 1.069 - 1.964, P<0.05) and chronic pain ( OR = 1.549, 95% CI 1.082 - 2.216, P<0.05) were the risk factors of mild cognitive impairment in elderly herders in Nanshan pastoral area. Conclusions:The prevalence rate of mild cognitive impairment among elderly herders in Nanshan pastoral area of Xinjiang is high, so it is necessary to carry out mild cognitive impairment screening as soon as possible, especially focusing on people suffering from hypertension, dyslipidemia and chronic pain, and making intervention plans to delay the occurrence and development of mild cognitive impairment and improve the quality of life of elderly herders.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

OBJECTIVE: To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12. RESULTS: In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred. CONCLUSIONS GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI. (Registration No. ChiCTR1800014291).

Hd-Zip, a unique transcription factor in plant kingdom, influences the growth, development, and secondary metabolism of plants. Hd-zip Ⅳ is thought to play an important role in trichome development of Schizonepeta tenuifolia. This study aims to explore the functions of StHD1 and StHD8 in Hd-zip Ⅳ subfamily in peltate glandular trichome development. To be specific, the expression patterns of the two genes and interaction between the proteins encoded by them were analyzed based on transcriptome sequencing and two-hybrid screening. The subcellular localization was performed and functions of the genes were verified in tobacco and S. tenuifolia. The results showed that StHD1 and StHD8 had high similarity to HD-Zip Ⅳ proteins of other plants and they all had the characteristic conserved domains of HD-Zip Ⅳ subfamily. They were located in the nucleus. The two genes mainly expressed in young tissues and spikes, and StHD1 and StHD8 proteins interacted with each other. The density and length of glandular trichomes increased significantly in tobacco plants with the overexpression of StHD1 and StHD8. Inhibiting the expression of StHD1 and StHD8 by VIGS(virus-induced gene silencing) in S. tenuifolia resulted in the reduction in the density of peltate glandular trichomes, the expression of key genes related to mono-terpene synthesis, and the relative content of limonene and pulegone, the main components of monoterpene. These results suggested that StHD1 and StHD8 of S. tenuifolia formed a complex to regulate glandular trichomes and affect the biosynthesis of monoterpenes.

Objective:To explore the relationship between seizure cluster of temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) and cortisol (COR) rhythm, and understand its mechanism from the perspective of neuroendocrine.Methods:Fifty-seven patients with unilateral TLE-HS were recruited from the Qinghai Provincial People′s Hospital from May 1st 2012 to December 31st 2020. According to the history of seizure clusters one month before admission, 27 patients were enrolled in seizure clusters group (SC group), 30 patients were included in without seizures cluster group (NSC group). The clinical characteristics were systematically analyzed and compared between the SC and NSC groups. Plasma COR levels were measured at 8:00, 16:00 and 24:00 (COR8, COR16 and COR0) on the same day, and bilateral magnetic resonance spectroscopy (MRS) diagnosis was performed in two groups. Independent sample t test, chi-square test, repeated analysis of variance, covariance analysis, and multivariate Logistic regression were used for statistical analysis. Results:Time effect, grouping effect and the interaction effect of the time and grouping in the level of COR were statistically significant. Covariance analysis excluded age as an influential factor, COR16, COR0 and the slope of COR8-16 in the SC group [(126.22±19.98) μg/L, (51.63±21.43) μg/L, -7.78±4.54] were higher than the NSC group [(97.70±18.55) μg/L, (31.90±10.73) μg/L, -12.40±4.16], and the difference was statistically significant ( F=5.587, 4.320, 4.013, all P<0.05). The slope of COR0-8 in the SC group (17.11±6.32) was lower than that in the NSC group (20.62±6.54), and the difference was statistically significant ( F=-2.065, P<0.05). There was no significant difference in lateralization of hippocampal sclerosis between the two groups, and there was no significant difference in the ratio of N-acetyl aspartic acid(NAA)/[choline(Cho)+creatinine(Cr)] in the unilateral hippocampal sclerosis zone of the two groups, but the NAA/(Cho±Cr) ratio of the contralateral hippocampus in the SC group (0.71±0.03) was lower than that in the NSC group (0.76±0.06),and the difference was statistically significant ( t=4.999, P=0.029). Multivariate Logistic regression analysis showed that COR16 ( OR=1.328, 95% CI 1.073-1.642, P=0.009), COR8-16 ( OR=3.657, 95% CI 1.404-9.525, P=0.008) were independent risk factors of seizure clusters in TLE-HS. Conclusion:COR rhythm disturbance may be the neuroendocrine basis of seizure clusters in patients with TLE-HS.

BACKGROUND: It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011. METHODS: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided). RESULTS: The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107). CONCLUSIONS: The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly. TRIAL REGISTRATION NUMBER NCT03620565, https://register.clinicaltrials.gov.

BACKGROUND: Drug-coated balloons (DCBs) have emerged as potential alternatives to drug-eluting stents in specific lesion subsets for de novo coronary lesions. Quantitative flow ratio (QFR) is a method based on the three-dimensional quantitative coronary angiography and contrast flow velocity during coronary angiography (CAG), obviating the need for an invasive fractional flow reserve procedural. This study aimed to assess the serial angiographic changes of de novo lesions post-DCB therapy and further explore the cut-off values of lesion and vessel QFR, which predict vessel restenosis (diameter stenosis [DS] ≥50%) at mid-term follow-up. METHODS: The data of patients who underwent DCB therapy between January 2014 and December 2019 from the multicenter hospital were retrospectively collected for QFR analysis. From their QFR performances, which were analyzed by CAG images at follow-up, we divided them into two groups: group A, showing target vessel DS ≥50%, and group B, showing target vessel DS <50%. The median follow-up time was 287 days in group A and 227 days in group B. We compared the clinical characteristics, parameters during DCB therapy, and QFR performances, which were analyzed by CAG images between the two groups, in need to explore the cut-off value of lesion/vessel QFR which can predict vessel restenosis. Student's t test was used for the comparison of normally distributed continuous data, Mann-Whitney U test for the comparison of non-normally distributed continuous data, and receiver operating characteristic (ROC) curves for the evaluation of QFR performance which can predict vessel restenosis (DS ≥50%) at mid-term follow-up using the area under the curve (AUC). RESULTS: A total of 112 patients with 112 target vessels were enrolled in this study. Group A had 41 patients, while group B had 71. Vessel QFR and lesion QFR were lower in group A than in group B post-DCB therapy, and the cut-off values of lesion QFR and vessel QFR in the ROC analysis to predict target vessel DS ≥50% post-DCB therapy were 0.905 (AUC, 0.741 [95% confidence interval, CI: 0.645, 0.837]; sensitivity, 0.817; specificity, 0.561; P < 0.001) and 0.890 (AUC, 0.796 [95% CI: 0.709, 0.882]; sensitivity, 0.746; specificity, 0.780; P < 0.001). CONCLUSIONS The cut-off values of lesion QFR and vessel QFR can assist in predicting the angiographic changes post-DCB therapy. When lesion/vessel QFR values are <0.905/0.890 post-DCB therapy, a higher risk of vessel restenosis is potentially predicted at follow-up.

Objective To analyze the components of proteins from Echinococcus granulosus cyst fluid using the shotgun method, and to identify the active components with potential regulatory effects for immune dysregulation diseases. Methods The E. granulosus cyst fluid was collected aseptically from the hepatic cysts of patients with cystic echinococcosis, and characterized by liquid chromatography (LC) tandem mass spectrometry (MS/MS) following digestion with trypsin. The protein data were searched using the software MaxQuant version 1.6.1.0 and the cellular components, molecular functions, and biological processes of the identified proteins were analyzed using the Gene Ontology (GO) method. Results The E. granulosus cyst fluid separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) had a relative molecular mass of 25 to 70 kDa. LS-MS/MS analysis identified 37 proteins, including 32 known proteins and 5 unknown proteins. At least 4 proteins were preliminarily found to exhibit potential regulatory effects for immune dysregulation diseases, including antigen B, glutathione-S-transferase (GST), thioredoxin peroxidase (TPX) and malate dehydrogenase (MDH). GO enrichment analysis showed that the identified proteins had 149 molecular functions and were involved in 341 biological processes. Conclusions E. granulosus cyst fluid has a variety of protein components, and four known proteins are preliminarily identified to be associated with immune dysregulation diseases.

Objective:This paper aims to clone the cDNA sequence of limonene-3-hydroxylase（StL3OH） in Schizonepeta tenuifolia and analyze its sequence by bioinformatics. Method:Specific primers were designed based on sequences of StL3OH gene screened from transcriptome sequencing data of S. tenuifolia and the cDNA sequence of StL3OH gene was cloned by reverse transcription polymerase chain reaction （RT-PCR） and analyzed for its bioinformatics. Result:The StL3OH gene cDNA sequence length was 1 598 bp，containing a 1 497 bp long complete open reading frame which encoded 498 amino acids. StL3OH protein had a theoretical relative molecular mass of 56.40 kDa，with a hydrophilic and unstable nature. Bioinformatics analysis showed that StL3OH protein had no signal peptide but had a transmembrane domain which might be located in endoplasmic reticulum. Multiple sequence alignment and cluster analysis showed that the amino acid sequence of MsL3OH protein had a high similarity with StL3OH protein，both of which contained cytochrome P450 heme binding region，belonging to the D subfamily of cytochrome CYP71 family. Codon bias analysis showed that StL3OH gene preferred guanine/cytosine（G/C） ending codon，with 27 skewed codons， and Nicotiana benthamiana was proven to be the most suitable host for exogenous expression of StL3OH gene. Conclusion:The cDNA sequence of StL3OH gene was cloned from S. tenuifolia for the first time，which will provide a basis for further study on the structure and function of StL3OH protein and the regulation mechanism of StL3OH gene in the accumulation and biosynthesis of monoterpenes in S. tenuifolia.
