OBJECTIVE: To observe the effects of Tiaoshu Anshen (regulating the hinge and calming the mind) acupuncture on sleep quality and serum levels of 5-hydroxytryptamine (5-HT) and dopamine (DA) in patients with chronic insomnia. METHODS: A total of 58 patients with chronic insomnia were randomly divided into an acupuncture group and a medication group, 29 cases in each group. Tiaoshu Anshen acupuncture was applied at Baihui (GV20) and bilateral Shenmen (HT7), Sanyinjiao (SP6), Benshen (GB13) in the acupuncture group, once a day, 1-day interval was taken after 6 consecutive days of treatment. Estazolam tablet was given orally before bed in the medication group, 1 mg each time. The 4-week treatment was required in both groups. Before and after treatment, the sleep quality was assessed by Pittsburgh sleep quality index (PSQI) and polysomnography (PSG), the serum levels of 5-HT and DA were detected by ELISA. RESULTS: After treatment, the item scores and total scores of PSQI were decreased compared with those before treatment in the two groups (P<0.05); in the acupuncture group, the scores of sleep quality, sleep latency, sleep time, sleep efficiency, sleep disorders and total score of PSQI were lower than those in the medication group (P<0.05). After treatment, the total sleep time (TST) was prolonged (P<0.05), the sleep latency (SL) and wake after sleep onset (WASO) were shortened (P<0.05), the sleep efficiency (SE%), percentage of non-rapid eye movement stage 3 (N3%), percentage of rapid eye movement stage (REM%) and serum levels of 5-HT were increased (P<0.05) compared with those before treatment; the percentage of non-rapid eye movement stage 1 (N1%), percentage of non-rapid eye movement stage 2 (N2%) and serum levels of DA were decreased (P<0.05) compared with those before treatment in the two groups. After treatment, in the acupuncture group, TST was longer, while SL and WASO were shorter than those in the medication group (P<0.05), SE%, N3%, REM% and serum level of 5-HT were higher, while N1%, N2% and serum level of DA were lower than those in the medication group (P<0.05). CONCLUSION Tiaoshu Anshen acupuncture may improve the sleep quality by regulating the serum neurotransmitter levels i.e. 5-HT and DA in patients with chronic insomnia.

OBJECTIVES: To verify whether hesperetin (Hes) alleviates doxorubicin (DOX)-induced cardiotoxicity by reducing inflammation via regulating the AMPK/NLRP3 pathway. METHODS: C57/bl6 mice and H9c2 cells treated with DOX to mimic cardiotoxicity were randomly divided into Sham (or control) group, DOX group, DOX+Hes group, DOX+Hes+compound C (CC, an AMPK inhibitor) group. Cardiac function and myocardial pathologies of the mice were evaluated, and the changes in H9c2 cell morphology and viability were assessed. Lactate dehydrogenase (LDH) activity in mouse myocardial tissues and H9c2 cells was measured using ELISA, and H9c2 cell apoptosis was detected with TUNEL staining. In both H9c2 cells and the myocardial tissues of the mice, cellular expression levels of TNF-α, IL-6 and IL-1β mRNAs and cleaved caspase-3, Bcl2, Bax, IL-1β, IL-18, p-AMPK, AMPK, p-mTOR, mTOR, NLRP3, ASC and caspase-1 proteins were detected using RT-PCR and Western blotting. RESULTS: DOX treatment caused cell swelling, decreased cell viability and increased LDH activity in H9c2 cells, resulting also in significantly increased cell apoptosis and cleaved caspase-3 expression and decreased Bcl2/Bax ratio. The DOX-treated mice showed obvious myocardial fiber swelling and inflammatory infiltration, decreased cardiac function and significantly increased myocardial LDH activity. In H9c2 cells, DOX treatment significantly increased the mRNA expressions of TNF-α, IL-6 and IL-1β and protein expressions of IL-1β and IL-18, lowered the expressions of p-AMPK and p-mTOR, and increased the expressions of NLRP3, ASC and caspase-1. Hes treatment obviously reduced these toxic effects of DOX in H9c2 cells, but its protective effects were blocked by application of compound C. CONCLUSIONS Hes reduces DOX-induced cardiotoxicity by inhibiting inflammation via regulating the AMPK/NLRP3 pathway.

Objectives:To evaluate the cost-effectiveness of typical pharmaceutical smoking cessation intervention strategies in China in the context of primary cancer prevention.Methods:Markov cohort simulation models were established to simulate the burden of 12 smoking caused cancer, including lung cancer, oral cancer, nasopharyngeal cancer, laryngeal cancer, esophageal cancer, gastric cancer, pancreatic cancer, liver cancer, kidney cancer, bladder cancer, cervical cancer, and acute myeloid leukemia. Taking incremental cost effectiveness ratio (ICER) as the main indicator, the model sets one year as the cycling period for 50 periods and simulates the cohort of 10 000 thirty-five-year-old current smokers with various smoking cessation strategies. To ensure the robustness of conclusion, univariate sensitivity analysis, probability sensitivity analysis, and age-group sensitivity analysis were conducted.Results:The results showed that varenicline intervention was the most cost-effective intervention. Compared to the next most effective option, incremental cost of each additional quality-adjusted life year is 11 140.28 yuan, which is below the threshold of willingness to pay (1 year GDP per capita). The value of ICER increased as the increasing age group of adopting intervention, but neither exceeded the threshold of willingness to pay. One-way sensitivity analysis showed that the value of discount rate, the hazard ratio and cost of intervention strategy had a greater impact on the result of ICER.Conclusion:In China, the use of varenicline to quit smoking is highly cost effective in the context of cancer primary prevention, especially for younger smokers.

Objective:To investigate the associations of onset age, diabetes duration, and glycated hemoglobin (HbA1c) levels with ischemic stroke risk in type 2 diabetes patients.Methods:The participants were from Comprehensive Research on the Prevention and Control of the Diabetes in Jiangsu Province. The study used data from baseline survey from December 2013 to January 2014 and follow-up until December 31, 2021. After excluding the participants who had been diagnosed with stroke at baseline survey and those with incomplete information on onset age, diabetes duration, and HbA1c level, a total of 17 576 type 2 diabetes patients were included. Cox proportional hazard model was used to calculate the hazard ratio ( HR) and 95% CI of onset age, diabetes duration, and HbA1c level for ischemic stroke. Results:During the median follow-up time of 8.02 years, 2 622 ischemic stroke cases were registered. Multivariate Cox proportional risk regression model showed that a 5-year increase in type 2 diabetes onset age was significantly associated with a 5% decreased risk for ischemic stroke ( HR=0.95, 95% CI: 0.92-0.99). A 5-year increase in diabetes duration was associated with a 5% increased risk for ischemic stroke ( HR=1.05, 95% CI: 1.02-1.10). Higher HbA1c (per 1 standard deviation increase: HR=1.17, 95% CI: 1.13-1.21) was associated with an increased risk for ischemic stroke. Conclusion:The earlier onset age of diabetes, longer diabetes duration, and high levels of HbA1c are associated with an increased risk for ischemic stroke in type 2 diabetes patients.

Objective To visualize the research status and hotspots of women's common disease screening based on CiteSpace 6.1.R6,and to provide a reference for the in-depth research in this field thereafter.Methods The relevant articles were retrieved from the China National Knowledge Infrastructure with the time in-terval from January 1,1992 to December 13,2022.The analysis was conducted on the number of annual publica-tions,countries(regions),institutions,author collaboration networks,keyword co-occurrence,clustering,and bursts.Results A total of 900 papers that met the criteria were included,and the number of annual publications showed a trend of first increasing and then decreasing.The cross-institutional collaboration network was mature.The re-search hotspots mainly covered women's health,the prevalence of women's diseases,reproductive health,and breast diseases.The hotspots have evolved from an initial focus on reproductive health care to gynecological disease management,and eventually to reproductive health and holistic health care in women.Conclusions The attention should be kept on the screening of women's common diseases.It is advisable to synchronize the screening of women's common diseases with the screening of cervical and breast cancers to expand the screening coverage,promote early disease detection and treatment,and comprehensively safeguard women's health.

Objective:To analyze the influencing factors of genotypic drug resistance mutations in people living with human immunodeficiency virus and acquired immunodeficiency syndrome(PLWHA) who failed anti-retroviral therapy (ART) in Henan Province, in order to provide a basis for adjusting ART regimens and reducing drug resistance.Methods:PLWHA with virological failure (human immunodeficiency virus (HIV) RNA≥500 copies/mL) after receiving ART for more than 24 weeks were included in Henan Province from January 2018 to December 2022. Baseline CD4 + T lymphocyte counts, ART regimens and other clinical data were collected. HIV-1 gene subtypes and their drug resistance sequence mutations were detected in the Sixth People′s Hospital of Zhengzhou, and the sequences were submitted to the HIV Drug Resistance Interpretation System of Stanford University for comparison of test results. Genotypic drug resistance to nucleotide reverse transcriptase inhibitors (NRTI), non-nucleoside reverse transcriptase inhibitors (NNRTI), protease inhibitors (PI) and integrase inhibitors (INSTI) was determined. Multivariate logistic regression was used to analyze the influencing factors of drug resistance in patients with ART failure. Results:Among 982 PLWHA, the sequences of 899 cases were successfully amplified, and drug resistance was detected in 737 cases, with the drug resistance rate of 81.98%(737/899). The rates of resistance to NRTIs, NNRTIs, PIs and INSTIs were 71.97%(647/899), 79.31%(713/899), 5.23%(47/899) and 2.72%(20/734), respectively.The largest number of those who developed concomitant resistance to two classes of drugs was 588 cases (79.78%), mainly NRTI and NNRTI concomitant resistance in 583 cases (79.10%). There were 99 cases (13.43%) who developed resistance to only one class of drugs, and those who developed concurrent resistance to three classes of drugs were 48 cases (6.51%), and two cases (0.27%) were found to be resistant to all four classes of drugs mentioned above. A total of 10 HIV genotypes were detected, among which subtype B accounted for the most (59.73%(537/899)), followed by circulating recombinant form (CRF)01_AE subtype (21.91%(197/899)) and CRF07_BC subtype (9.45%(85/899)). The risk factors affecting the development of drug resistance were baseline CD4 + T lymphocyte counts, ART regimens and HIV-1 genotypes. The risk of drug resistance in patients with baseline CD4 + T lymphocyte counts <100/μL was 4.55 times (95% confidence interval ( CI) 2.69 to 7.70) higher than patients with CD4 + T lymphocyte counts≥250/μL, the risk of drug resistance in patients using 2NRTIs+ NNRTI regimen was 4.51 times (95% CI 1.75 to 11.63) higer than those using 2NRTIs+ INSTI regimen, and patients infected with B and CRF01_AE subtype was 2.18 times (95% CI 1.10 to 4.29) and 2.70 times (95% CI 1.26 to 5.78) higer than those with CRF07_BC subtype, respectively. Conclusions:The incidence of genotypic drug resistance in PLWHA with ART failure in Henan Province is high. Low baseline CD4 + T lymphocyte counts, 2NRTIs+ NNRTI regimens, and genotype B and CRF01_AE are risk factors for drug resistance in PLWHA.

Objective:To investigate the effects of glycopyrrolate on intestinal spasm and hemodynamics in painless colonoscopy.Methods:A total of 100 patients who were scheduled to undergo painless colonoscopy were selected as the study subjects and randomly divided into two groups by a computerized number method. Ten patients in both groups dropped out because of disruption of the study protocol, and 45 patients from each group were included in the final analysis. Before anesthesia induction, patients in group glycopyrrolate (group G) were injected with 0.2 mg glycopyrrolate, while those in congtrol group (group C) were injected with an equal amount of saline. The heart rate, systolic blood pressure, and diastolic blood pressure were recorded at T 0 (baseline period), T 1 (after anesthesia induction), T 2 (colonoscopy over sigmoid colon), T 3 (colonoscopy over the liver region), T 4 (after the end of examination), and T 5 (at the awakening phase), and the degree of intestinal spasm was assessed intraoperatively using the Likert′s four-point scale. The numerical rating scale (NRS) was used to assess preoperative and postoperative pain. The incidence of adverse events was recorded. Results:The general data at baseline were not statistically different between the two groups ( P>0.05). During the procedure, patients in group G had lower intraoperative intestinal spasm scores than those in group C ( P=0.028). Intraoperative hypotension and bradycardia occurrence were lower in group G than in group C ( P<0.05), and intraoperative norepinephrine use was also lower than in the group C ( P=0.034). Postoperative visual analog scale pain scores were lower in group G ( P=0.047), but patients who used glycopyrrolate had a higher proportion of dry mouth ( P=0.035). Conclusion:During painless colonoscopy, preoperative administration of glycopyrrolate significantly improved intraoperative hemodynamic fluctuations, reduced the incidence of hypotension and bradycardia, and relieved postoperative pain. However, glycopyrrolate use resulted in the risk of dry mouth.

African swine fever(ASF),caused by the African swine fever virus(ASFV),is a highly contagious infectious disease of pigs.This disease has been spread rapidly in China since 2018,po-sing a huge threat to China's pig farming industry.To rapid detect the ASFV,a loop-mediated iso-thermal amplification(LAMP)combined with the disposable nucleic acid visualization test strip was established for visual detection of the nucleic acid of ASFV B646L gene.The method was easy to operate without special instruments and equipment,while it effectively avoided the disadvantage of false positives caused by aerosol contamination.The method was able to detect 1.16 copies/μL of the recombinant plasmid in 50 min at 65 ℃.In addition,the method was specific with no cross-re-action with classical swine fever virus,porcine reproductive and respiratory syndrome virus,por-cine parvovirus,transmissible gastroenteritis virus.The results in this study provides a rapid,con-venient,sensitive and reliable method for early diagnosis and screening for ASFV suspected infec-tion cases.

The PCR-amplified severe fever with thrombocytopenia syndrome virus(SFTSV)Gn-DⅢ-Ⅲ gene was inserted into the pET-30a(+)prokaryotic expression vector to generate the re-combinant plasmid pET-SFTSV-Gn-D Ⅲ-Ⅲ.The plasmid was transformed into E.coli BL21(DE3)for Gn-DⅢ-m protein expression and the expression conditions were optimized.The Gn-DⅢ-Ⅲ protein purified with Ni-NTA column affinity chromatography was applied as the captured antigen to establish an indirect ELISA method for the detection of SFTSV antibody.The results demonstrated that the recombinant plasmid pET-SFTSV-Gn-D Ⅲ-Ⅲ was successfully constructed as identified by PCR and sequencing.The recombinant protein SFTSV Gn-D m-Ⅲ was soluble ex-pression in E.coli under the optimal induction conditions of 0.4 mmol/L IPTG at 25 ℃ for 4 h,and the protein purity was 91.77％after purification by Ni-NTA column.The optimal reaction con-ditions for the indirect ELISA of SFTSV antibody were as follows:coating antigen concentration(5 μg/mL),primary antibody(incubation at 37 ℃ for 1.5 h),and secondary antibody(diluted 1:10 000 and incubated at 37 ℃ for 1 h).The established method had no cross-reactivity with Rift Valley fever virus(RVFV),Ebola virus(EBOV),and tick-borne encephalitis virus(TBEV)posi-tive sera.The method had a high sensitivity,with P/N＞2.1 for SFTSV-positive sera diluted to 81920.Coefficients of variation for intra-and inter-batch reactions were less than 10％.Detection of four SFTSV-infected human clinical serum samples showed the serum samples from patients in re-mission were tested as positive(P/N＞2.1),while serum samples from patients with multiple or-gan failure were detected as negative(P/N＜2.1).The results indicated that the SFTSV Gn-D Ⅲ-Ⅲ protein was successfully expressed and purified,and it was used as the coating protein to estab-lish an indirect ELISA assay for SFTSV antibody,which possesses good specificity,sensitivity and reproducibility.This method might be applied to detect human SFTSV clinical serum samples.

Objective:To establish the reference values and growth curves of skeletal muscle mass among children in the Nanjing area.Methods:A cross-sectional study was conducted with children who underwent physical examination at the Department of Child Health Care, Children′s Hospital of Nanjing Medical University from 2020 January to 2022 September. Their height, weight, body fat mass and skeletal muscle mass were measured. Body mass index, percentage of body fat mass, percentage of skeletal muscle mass, relative skeletal muscle mass index and the ratio of skeletal muscle to body fat were calculated. The associations between skeletal muscle mass indices and physical measurements index were analyzed through the Spearman correlation test. The Mann-Kendall test was used to assess the trend for skeletal muscle mass. Generalized additive models for location, scale and shape were used to construct percentile reference values and growth curves of male and female skeletal muscle mass indices at different ages.Results:A total of 32 690 children aged 4-14 years were enrolled in this study, including 19 912 boys (60.91%). Skeletal muscle mass, percentage of skeletal muscle mass, relative skeletal muscle mass index and the ratio of skeletal muscle to body fat of boys and girls was 11.10 (8.40, 14.90) and 10.30 (7.90, 13.20) kg, 40.36% (37.01%, 43.13%) and 39.38% (36.43%, 41.88%), 6.70 (6.07, 7.52) and 6.33 (5.79, 7.00), 2.39 (1.46, 3.47) and 2.14 (1.45, 3.00) kg/m 2, respectively. Skeletal muscle mass of both boys and girls was all positively associated with weight ( r=0.97, 0.96), body mass index ( r=0.68, 0.63) and percentage of body fat mass ( r=0.40, 0.43) (all P<0.01). The reference values and growth curves showed that the percentage of skeletal muscle mass P50 ranged from 37.75%-44.61% in boys and from 36.22%-40.55% in girls. The relative skeletal muscle mass index P50 ranged from 5.80-9.68 kg/m 2 in boys and from 5.57-7.98 kg/m 2 in girls. The ratio of skeletal muscle to body fat P50 ranged from 1.86-2.67 in boys and from 1.29-2.41 in girls. There was an increasing trend with age for both boys and girls in the growth of skeletal muscle mass ( Z=4.20, 3.75, both Ptrend<0.01), and increased slightly before 9 years of age and then increased rapidly until 14 years of age in both boys and girls. Conclusions:The skeletal muscle mass indices change with age and gender during childhood. Percentile reference values for pediatric skeletal muscle mass indices can be used to evaluate the muscular growth and development in children in the Nanjing area.
