Peptidomic analysis of follicular fluid in patients with polycystic ovarian syndrome.

Objective: The aim of this study was to analyze and compare the differential expression of peptides within the follicular fluid of polycystic ovary syndrome (PCOS) patients versus normal women by using peptidomics techniques. The underlying mechanisms involved in PCOS pathogenesis will be explored, together with screening and identification of potential functional peptides via bioinformatics analysis. Materials and methods: A total of 12 patients who underwent in vitro fertilization and embryo transfer (IVF-ET) at the Reproductive Medicine Center of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from 1 September 2022 to 1 November 2022 were included in this study. The follicular fluid of PCOS patients (n = 6) and normal women (n = 6) were collected. The presence and concentration differences of various peptides were detected by the LC-MS/MS method. GO and KEGG analysis were performed on the precursor proteins of the differentially-expressed peptides, and protein network interaction analysis was carried out to identify functionally-relevant peptides among the various peptides. Results: A variety of peptides within the follicular fluid of PCOS versus normal patients were detected by peptidomics techniques. Altogether, 843 upregulated peptides and 236 downregulated peptides were detected (absolute fold change ≥2 and p < 0.05). Of these, 718 (718 = 488 + 230) peptides were only detected in the PCOS group, while 205 (205 = 174 + 31) were only detected in the control group. Gene Ontology enrichment and pathway analysis were performed to characterize peptides through their precursor proteins. We identified 18 peptides from 7 precursor proteins associated with PCOS, and 4 peptide sequences were located in the functional domains of their corresponding precursor proteins. Conclusion: In this study, differences in the follicular development of PCOS versus normal patients were revealed from the polypeptidomics of follicular development, which thus provided new insights for future studies on the pathological mechanisms of PCOS development.

Optimized electroacupuncture treatment for female stress urinary incontinence: study protocol for a multi-center randomized controlled trial.

Background: Stress urinary incontinence (SUI) is a common condition that can severely affect women's life quality. Electroacupuncture (EA) has been proved to be an optional treatment for SUI, but the tolerance of EA becomes a factor affecting efficiency, which should not be ignored and needs to be solved urgently. The purpose of this study is to find out whether the use of alternating acupoints combination can solve this problem or not and provide an optimization of EA treatment for female SUI. Methods: This multi-center randomized controlled trial will enroll 360 patients with SUI. They will be randomly assigned to one of the three groups-sacral acupoints group (sacral group), abdominal acupoints group (abdominal group), or alternating acupoints group (alternating group)-at a 1:1:1 ratio. The patients will receive 18 sessions of EA treatment and will be followed up for 48 weeks after the treatment. The primary outcome measure of the study is the change of urine leakage at week 6. The secondary outcomes include the incontinence episode frequency (IEF), International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), severity of SUI, patient self-evaluation of therapeutic effects, weekly usage of urine pads, ultrasonography of pelvic floor, specialty therapies for SUI, evaluation of discomfort during EA treatment, patient acceptability evaluation and adverse events related to intervention. Discussion: This trial is specifically designed to offer an optimized EA treatment for female SUI, aiming to enhance their quality of life.Clinical trial registration: ClinicalTrials.gov, identifier ID:NCT05635669.

New ophiobolin sesterterpenoid and drimane sesquiterpenoids from a marine-alga-derived fungus Aspergillus sp.

Further investigation of secondary metabolites of a marine-alga-derived fungus Aspergillus sp. RR-YLW-12 led to isolate one new ophiobolin-type sesterterpenoid (1), four new drimane-type sesquiterpenoids (2-5) and one natural occurring compound (6), together with seven known compounds (7-13). Their structures and stereochemistry were elucidated by extensive spectroscopic analysis of NMR and HRMS experiments, and by comparison with the literature data. All isolates were evaluated for growth inhibition of five marine harmful microalgae. The new compounds exhibited significant to moderate inhibitory effects towards all tested microalgae species with IC50 values ranging from 5.8 to 54.5 µg/mL.

Effects of body mass index on IVF outcomes in different age groups.

BACKGROUND: Herein, we aimed to analyse the effects of body mass index (BMI) on the treatment outcomes of in vitro fertilisation (IVF) in a cohort of women undergoing their first IVF cycle. METHODS: A total of 2311 cycles from 986 women undergoing their first IVF/intracytoplasmic sperm injection cycle with fresh/frozen embryo transfer between January 2018 and December 2021 at the Center of Reproductive Medicine, Shuguang Hospital affiliated to Shanghai University of Traditional Chinese Medicine, were considered in this retrospective cohort study. First, the included patients were classified into four groups based on their BMI: underweight (BMI < 18.5 kg/m2, 78 patients), normal weight (18.5 ≤ BMI < 24 kg/m2, 721patients), overweight (24 ≤ BMI < 28 kg/m2, 147 patients), and obese (BMI ≥ 28 kg/m2, 40 patients). The IVF outcomes included the Gn medication days; Gn dosage; number of retrieved oocytes, mature oocytes, fertilized oocytes, cleavages, and available embryos and high-quality embryos; implantation rate; clinical pregnancy rate and live birth rate. Next, all the obtained data were segregated into three different subgroups according to the patient age: < 30 years, 30-38 years and > 38 years; the IVF pregnancy outcomes were compared among the groups. RESULTS: Compared with the other three groups, the underweight group had a higher number of fertilized oocytes, cleavage and available embryos and a smaller Gn medication days and required a lower Gn dosage. There was no difference in the number of retrieved oocytes and mature oocytes among the groups. Moreover, compared with the women aged 30-38 years in the overweight group, those in the normal weight group had a significantly higher implantation rate, clinical pregnancy rate and live birth rate (p = 0.013 OR 1.75, p = 0.033 OR 1.735, p = 0.020 OR 1.252 respectively). The clinical pregnancy rate was also significantly higher in those aged 30-38 years in the normal weight group than in the obese group (p = 0.036 OR 4.236). CONCLUSIONS: Although the BMI can greatly affect the pregnancy outcomes of women aged 30-38 years, it has almost no effects on the outcomes of younger or older women.

Analysis of factors influencing patient delay by patients with pulmonary tuberculosis in Lishui City, Zhejiang Province.

OBJECTIVE: The purpose of this study was to collect data on the current state of patient delay by patients with tuberculosis (TB) in Lishui City, Zhejiang Province who were under the care of a TB-designated hospital from 2011 to 2021 and to analyze the factors that contribute to this problem in order to provide a scientific basis for the prevention and control of TB. METHODS: In this observational study, we collected data on patients with pulmonary TB that were reported to the Chinese government's disease prevention and control information system by the Traditional Chinese Medicine Hospital in Lishui City between 2011 and 2021. The data included demographics like age, gender, occupation, household registration, current address, date of symptoms, date of first visit, and etiology results. Multivariate logistic regression analysis was used to analyze the factors influencing patient delay by patients with pulmonary TB. RESULTS: There were 3,190 cases of pulmonary TB treated in a TB-designated hospital in Lishui City, Zhejiang Province, between 2011 and 2021. Of these, 2,268 involved patient delay, with the delay rate of 71.10% and the median (Q25, Q75) days of patient delay being 36 (25, 72) days. Results of multivariate logistic regression analysis indicated the presence of risk factors-age > 60 years old (OR = 1.367, 95% CI: 1.144 ~ 1.632), pathogen positive (OR = 1.211, 95% CI: 1.033 ~ 1.419), and employed as peasants (OR = 1.353, 95% CI:1.144 ~ 1.601) for patient delay in patients with pulmonary TB. Patients with diabetes mellitus made up 64.94% of the pulmonary TB population, which was lower than the 71.58% of patients without diabetes mellitus (χ2 = 4.602, P = 0.032). Additionally, the presence of diabetes mellitus may be a protective factor in patient delay in patients with pulmonary TB (OR = 0.641, 95% CI: 0.481 ~ 0.856). CONCLUSION: High rates of patient delay, age > 60 years old, a positive etiology, and being employed as peasants are all possible risk factors for pulmonary TB in Lishui City, Zhejiang Province.

[Immediate analgesic effect of electroacupuncture combined with diclofenac sodium on acute gouty arthritis: a randomized controlled trial].

OBJECTIVE: To observe the immediate analgesic effect of electroacupuncture (EA) combined with diclofenac sodium on acute gouty arthritis (AGA). METHODS: A total of 90 patients with AGA were randomly divided into a low-dose medication (LM) group (30 cases, 1 case was eliminated, 1 case dropped off), a conventional medication (CM) group (30 cases, 1 case dropped off) and a combination of acupuncture and medication (AM) group (30 cases ). The LM group was given oral administration of 50 mg diclofenac sodium sustained-release capsule; the CM group was given oral administration of 100 mg diclofenac sodium sustained-release capsule; on the basis of the treatment of LM group, the AM group was treated with electroacupuncture at ashi points, Dadu (SP 2), Taichong (LR 3), Taibai (SP 3), Neiting (ST 44), Sanyinjiao (SP 6), Zusanli (ST 36) and Yinlingquan (SP 9) on the affected side, and Taichong (LR 3) and Zusanli (ST 36), Sanyinjiao (SP 6) and Yinlingquan (SP 9) were connected to electroacupuncture respectively, continuous wave, 2 Hz in frequency. The visual analogue scale (VAS) scores of pain before treatment and after 10 min, 2 h, 4 h and 6 h of treatment completion, joint tenderness and swelling scores before treatment and after 10 min and 6 h of treatment completion were compared, and the rate of diclofenac sodium addition within 24 h after treatment completion was recorded among the three groups. RESULTS: After 10 min of treatment completion, the scores of VAS, joint tenderness and joint swelling in the AM group were lower than those before treatment (P<0.05), and the VAS score in the AM group was lower than that in the other two groups (P<0.05). After 2, 4 and 6 h of treatment completion, the VAS scores of the three groups were lower than those before treatment (P<0.05), and the scores in the AM group were lower than those in the LM group (P<0.05). After 6 h of treatment completion, the joint tenderness scores of the three groups and the joint swelling scores of the AM group and the CM group were lower than those before treatment (P<0.05), and the joint tenderness and swelling scores of the AM group were lower than those of the LM group (P<0.05). The rate of diclofenac sodium addition was 3.3 % (1/30) and 3.4 % (1/29) in the AM group and the CM group, respectively, which were lower than 17.9% (5/28) in the LM group (P<0.05). CONCLUSION: Electroacupuncture combined with diclofenac sodium have a good immediate analgesic effect in the treatment of AGA, and have the advantages of small dosage of analgesic drugs and less adverse reactions.

Assessment of Effective Anti-TB Regimens and Adverse Outcomes Related Risk Factors in the Elderly and Senile-Aged TB Patients.

Objective: Compared to younger patients with tuberculosis (TB), elderly and senile-aged patients with TB had a higher incidence of adverse outcomes particularly in terms of lost to follow-up and deaths. Our study aimed to gain insight into the effectiveness of anti-tuberculosis (anti-TB) treatment in the elderly or senile-aged patients and identify the risk factors for adverse outcomes. Methods: The case information was obtained from the "Tuberculosis Management Information System". From January 2011 to December 2021, this retrospective analysis was conducted in Lishui City, Zhejiang Province to observe and record the outcomes of elderly patients diagnosed with TB who agreed to receive anti-TB and(or) traditional Chinese medicine(TCM) treatment. We also employed a logistic regression model to analyze the risk factors for adverse outcomes. Results: Among the 1191 elderly or senile-aged patients with TB who received the treatment, the success rate was 84.80% (1010/1191). Using logistic regression analysis, several risk factors for adverse outcomes (failure, death, loss to follow-up) were identified, including age ≥ 80 years (OR 2.186, 95% CI 1.517~3.152, P<0.001), lesion area ≥ 3 lung fields (OR 0.410, 95% CI 0.260~0.648, P<0.001), radiographic lesions failing to improve after 2 months of treatment (OR 2.048, 95% CI 1.302~3.223, P=0.002), sputum bacteriology failing to turn negative after 2 months of treatment (OR 2.213, 95% CI 1.227~3.990, P=0.008), lack of a standardized treatment plan (OR 2.095, 95% CI 1.398~3.139, P<0.001), and non-involvement of traditional Chinese medicine (OR 2.589, 95% CI 1.589~4.216, P<0.001). Conclusion: The anti-TB treatment success rate in the elderly and senile-aged patients is suboptimal. Contributing factors include advanced age, extensive lesions, and low sputum negative conversion rate during the intensive treatment phase. The results will informative and could be useful for policy maker for to control of reemergence of TB in big cities.

Pharmacokinetic analysis for simultaneous quantification of Saikosaponin A- paeoniflorin in normal and poststroke depression rats: A comparative study.

Bupleurum and Paeonia are common compatibilities for the treatment of depression, most of which are used in classical prescriptions. The main active ingredients saikosaponin A (SSA) and paeoniflorin (PF) have significant therapeutic effects on poststroke depression (PSD). However, the pharmacokinetic (PK) behavior based on the combination of the two components has not been reported in rats. The aim of this study was to compare the pharmacokinetic characteristics of combined administration of SSA and PF in normal and PSD rats. Plasma samples were collected after SSA and PF were injected into the rat tail vein, and plasma pretreatments were analyzed by HPLC. Based on the concentration levels of SSA and PF in plasma, Drug and Statistics 3.2.6 (DAS 3.2.6) software was used to establish the blood drug concentration model. PK data showed that compared with the normal rats, the values of related parameters t1/2α, AUC(0-t), AUC(0-∞) were decreased in diseased rats, while the values of CL1 was increased. These findings suggest that PSD can significantly affect the PK parameters of SSA-PF. This study established a PK model to explore the time-effect relationship, in order to provide experimental and theoretical support for clinical application.

[Effects of electroacupuncture on pregnancy outcome in poor ovarian response patients of kidney essence deficiency and undergoing in vitro fertilization-embryo transfer].

OBJECTIVE: To observe the effects of electroacupuncture (EA) on ovarian reaction, egg and embryo quality, as well as pregnancy rate in poor ovarian response (POR) patients of kidney essence deficiency and undergoing in vitro fertilization-embryo transfer (IVF-ET). METHODS: Ninety-six patients who met the inclusion criteria were randomly divided into an EA group and a control group, with 48 cases in each group. Before IVF-ET, the patients in the EA group received EA, once daily, 2 or 3 treatments a week for 12 weeks. Before and after the treatment, traditional Chinese medicine (TCM) syndrome score and clinical pregnancy rate were assessed in two groups. The concentrations of serum follicle-stimulating hormone (FSH), luteinsing hormone, estradiol, progesterone and anti-mullerian hormone were detected by chemiluminescence; the contents of serum insulin-like growth factor-1, serum inhibin B (INHB) and Kisspeptin in follicular fluid were determined by enzyme linked immunosorbent assay (ELISA); the antral follicle counting (AFC) was detected by color Doppler ultrasonography; and the egg and embryo conditions were observed under microscope. Fourteen days after embryo transfer, the positive rate of serum hemchoriconic gonadotropin (HCG) and clinical pregnancy rate were calculated. RESULTS: After the treatment, the TCM syndrome score and level of serum FSH were reduced (P<0.05); the INHB in serum and AFC were increased (P<0.05) when compared with those before the treatment in the EA group. After the treatment, in comparison with the control group, the TCM syndrome score and level of serum FSH were lower (P<0.05); and the contents of serum INHB, AFC, the numbers of MⅡ eggs and high-quality embryos, as well as serum HCG positive rate were all increased (P<0.05) in the EA group. CONCLUSION: EA can relieve the clinical symptoms of TCM in POR patients of kidney essence deficiency and undergoing IVF-ET, increase the ovarian reserve, reduce the serum FSH level, and improve the content of serum INHB, and the quality of eggs and embryos. This therapy tends to improve the clinical pregnancy rate and clinical pregnancy outcome.

"Huoling Shengji granule" for amyotrophic lateral sclerosis: protocol for a multicenter, randomized, double-blind, riluzole parallel controlled clinical trial.

Background: There is still a large demand for effective treatments to delay disease deterioration in amyotrophic lateral sclerosis (ALS). Typical symptoms of ALS are considered "flaccidity syndrome" in traditional Chinese medicine (TCM). Huoling Shengji Granule (HLSJ) is a TCM formula used to treat flaccidity syndrome. Results of preclinical tests and a previous clinical study support HLSJ as a novel drug for ALS patients. This trial proposed to examine whether a 48-week course of HLSJ is effective and safe for ALS patients diagnosed with the Chinese medicine syndrome of spleen qi insufficiency and kidney yang deficiency. Methods and analysis: In this phase II, multicenter, randomized, double-blind, riluzole parallel-controlled, superiority-design study, eligible participants had the equal opportunity to be assigned to receive either HLSJ or riluzole randomly. Eleven specialized ALS centers in Mainland China will recruit 144 patients for this trial. The primary and secondary outcomes included the change in the ALSFRS-R score and the Rasch-Built Overall Amyotrophic Lateral Sclerosis Disability Scale (ROADS) from baseline to Week 48. Discussion: Here, we endeavored to evaluate TCM for ALS using a standard evidence-based approach for the first time. In addition, the ROADS, a self-report linear-weighted questionnaire, was selected as a secondary outcome measure. We expect to offer a new reference for the outcome evaluation of ALS trials.Clinical trial registration:http://www.Chictr.org.cn, identifier ChiCTR2100044085.

Non-pharmaceutical interventions in complementary and alternative medicine for insomnia in breast cancer survivors: a protocol for a systematic review and network meta-analysis.

INTRODUCTION: Insomnia has a high incidence in patients with breast cancer, which not only affects the quality of life of patients, but also affects the efficiency of later treatment and rehabilitation. Although the sedative and hypnotic drugs commonly used in clinical practice have a rapid onset of action, they are also accompanied by different degrees of sequelae, withdrawal effects and dependence and addiction. Complementary and alternative medicine (CAM) or complementary and integrative medicine, complementary integrative therapies, including natural nutritional supplement therapy, psychotherapy, physical and mental exercise, physiotherapy, have been reported to be used to treat cancer-related insomnia. Its clinical results are increasingly recognised and accepted by patients. However, the effectiveness and safety of these CAM are uneven, and there is no standard clinical application method. Therefore, in order to objectively evaluate the effects of different non-pharmaceutical interventions in CAM on insomnia, we will conduct a network meta-analysis (NMA) to explore the effects of different CAM interventions on improving sleep quality in patients with breast cancer. METHODS AND ANALYSIS: We will search all Chinese and English databases from the inception of the database to 31 December 2022. The databases include PubMed, Medline, Embase, Web of Science and Cochrane Central Register of Controlled Trials and the Chinese literature databases include CBM, CNKI, VIP, WANFANG. The Insomnia Severity Index and the Pittsburgh Sleep Quality Index will be considered as the primary outcomes in the study. STATA V.15.0 software will be used to conduct pairwise meta-analysis and NMA. Finally, we will use the recommended risk assessment tool RoB2 for risk and bias assessment, and use the Grading of Recommendations Assessment, Development and Evaluation evaluation method to evaluate the quality of evidence. ETHICS AND DISSEMINATION: Ethical approval will not be required because the study will not include the original information of participants. The results will be published in a peer-reviewed journal or disseminated in relevant conferences. PROSPERO REGISTRATION NUMBER: CRD42022382602.

Effect of Lianhua Qingwen capsules on the positive rate of COVID-19 close contacts: A retrospective analysis of a large-scale population-based cohort study.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is still spreading worldwide. COVID-19 close contact is a key point of this epidemic. However, no medication is now available for close contact. This study aims to evaluate the beneficial effect and safety of the Lianhua Qingwen capsule (LHQW) on COVID-19 close contacts via a large, retrospective cohort study. METHODS: A total of 25,002 close contacts from 199 quarantine sites in Changchun, Jilin, who underwent medical observation, were included. The information about these close contacts were collected for further epidemiological research. Moreover, subjects were divided into an exposure group (LHQW group, oral, 4 capsules/time, t.i.d.; 18,579 subjects) and a non-exposure group (control group; 6,423 subjects). Inverse probability of treatment weighting (IPTW) with propensity score was employed to evaluate the positive rate of the SARS-CoV-2 nucleic acid test in nasal and throat swabs confirmed by polymerase chain reaction (PCR). RESULTS: A total of 22,975 subjects were included in the analysis, 17,286 cases in the LHQW group and 5,689 cases in the control group. The positive rate of nucleic acid testing in the LHQW group was 5.12%, and that in the control group was 9.70% before the adjustment of IPTW of the propensity score; the difference between the two groups was -4.58% (95% CI -5.44- -3.77%, p <  0.001). After adjusting IPTW, the positive rate of nucleic acid testing in the LHQW group and the control group was 5.10% and 9.80%, respectively; the difference between the two groups was -4.70% (95% CI -5.18- -4.23, p < 0.001). The conclusions before and after the IPTW adjustment were consistent. No test drug-related adverse reactions were observed during the study period. CONCLUSION: LHQW has a beneficial effect and safety on the close contacts of SARS-CoV-2 who are under medical observation at the quarantine sites and can be used as an optional drug for those close contacts.

The Nature and Types of Community Palliative and end-of-Life Care Services: A Content Analysis of Service Provider Websites in Hong Kong.

OBJECTIVE: To analyze the nature and types of community palliative and end-of-life care (PEoLC) services in Hong Kong in order to inform future service development. METHODS: This cross-sectional descriptive study systematically searched the eligible websites of service providers concerning community PEoLC services for patients and their family caregivers using the Hong Kong version of the Google Search engine in August 2021. Search terms included different traditional Chinese translations of palliative care, end-of- lifecare, and hospice care. For the included websites, information regarding the characteristics and types of PEoLC services were extracted and coded using content analysis. RESULTS: Sixteen websites providing community PEoLC services were included in this analysis, which were almost all provided by non-governmental organizations (NGOs). Around half of the service providers targeted the geriatric group and served the population in some major geographic areas and districts only. Ten types of services were identified, including (1) information and advice; (2) psychological support; (3) dying and bereavement care; (4) spiritual support; (5) medical and nursing care; (6) leisure and social well-being activities; (7) support with household and other practical tasks; (8) referral resources; (9) financial support; and (10) caregiving skills training. CONCLUSION: Existing community PEoLC services in Hong Kong are provided mainly by NGOs, with a focus on comprehensive care for patients in some areas and districts but few support services for caregivers. There is a need for continued efforts to optimize the PEoLC services to support patients and caregivers locally.

Tibial nerve electrical stimulation for fecal incontinence: a systematic review and meta-analysis.

Tibial nerve stimulation (TNS) therapy is widely used to treat fecal incontinence (FI), but still, some controversy exists. This study aimed to determine whether TNS could improve FI from different evaluation angles. A systematic review and meta-analysis were conducted to provide indirect evidence of TNS treatment for FI. We searched for the original studies in PubMed, Embase, Web of Science, Ebsco Medline, Ovid Medline, and Cochrane Central Register of Controlled Trials published before November 31, 2021. The standardized mean difference was the efficacy analysis statistic, and the effect was expressed by the 95% confidence interval (CI). For the case series, we calculated the mean difference of the number of patients evaluated at baseline and last follow-up. Four randomized controlled trials (RCTs, four hundred and sixty participants) and eighteen case series (eight hundred and thirty-eight participants) were included in the study. The results of the RCTs showed that the number of weekly episodes of FI significantly reduced in the TNS group compared with the sham stimulation group. The results of the case series showed that TNS reduced the number of patients with FI per week. The Cleveland Clinic Florida FI Score significantly reduced. The post-treatment results of maximum squeeze pressure and maximum resting pressure were significantly different from baseline. This study showed that TNS to some extent reduced the number of patients with FI, reduced clinical symptoms, and improved anal physiological function. Despite the low quality of overall evidence, TNS still shows some potential as a safe treatment for FI.

Electroacupuncture improves follicular development and metabolism and regulates the expression of adiponectin, AMPK and ACC in an obese rat model of polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by hyperandrogenism and follicular arrest. Electroacupuncture (EA) has been shown to be effective at improving hyperandrogenism and follicular arrest in PCOS; however, its mechanism of action remains to be deciphered. OBJECTIVE: In this study, we investigated whether EA improved follicular development in an obese rat model of PCOS and regulated the expression of adiponectin, AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC). METHODS: EA was administered at CV3, CV4 and ST40. Changes in body weight, paraovarian fat, estrus cycle, ovarian morphology, levels of related hormones, and glucose and lipid metabolism were evaluated. In addition, protein and mRNA expression of adiponectin, AMPK and ACC was measured. RESULTS: The body weight and paraovarian fat of rats in the EA group were reduced, while estrus cyclicity and ovarian morphology improved. Levels of free fatty acids, triglycerides, total cholesterol and low-density lipoprotein cholesterol were significantly reduced in the EA group, as well as blood glucose levels. Furthermore, levels of testosterone and luteinizing hormone were reduced in the EA group, while estradiol levels were increased. Protein and mRNA expression of adiponectin, AMPKα1 and liver kinase B1 (LKB1) was found to be increased in the EA group, while protein and mRNA expression of ACC were significantly reduced.Conclusion: Our findings suggest that EA improved follicular development and metabolism and regulated expression levels of adiponectin, AMPKα1, LKB1 and ACC in our obese rat model of PCOS.

Neurological mechanism and efficacy of acupuncture for breast cancer-related insomnia: a study protocol for randomized clinical trial.

Background: Breast cancer survivors (BCSs) are at a higher risk of developing insomnia. The negative effects of cancer-related insomnia (CRI) include depression, anxiety, fatigue, aggressive pain, impaired immune functioning, decreased quality of life, and even increased cancer mortality. Although preliminary progress has been made in the treatment of CRI with acupuncture, the evidence is insufficient and the neurological mechanism underlying the effect of acupuncture is still unclear. Methods: The study employs a single-blinded, randomized, controlled trial design. A total of 80 participants will be randomly allocated in a 1:1 ratio to either the treatment group (n = 40) or the control group (n = 40). The former will receive acupuncture treatment, while the latter will receive sham acupuncture treatment. Both groups will receive 12 sessions over a 4-week period, three times per week (every other day), and each session will last for 30 min. Follow-up assessments will be conducted in week 8. The primary outcome will be the treatment response rate. Secondary outcomes include the change in Insomnia Severity Index (ISI), the treatment remission rate, actigraphy sleep assessment, Generalized Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Quality of Life Core Scale (QLQ-C30), the weekly usage of remedial drugs, and functional magnetic resonance imaging (fMRI) analysis. Data for the outcomes will be collected at week 0 (the baseline), week 1 (the intervention period), week 4 (the post-treatment period), and week 8 (the follow-up period). Discussion: The objective of this study is to assess the efficacy of acupuncture for patients with CRI in comparison with sham acupuncture. Additionally, the research aims to explore the neuropathological mechanisms of CRI and provide the first evidence on the characteristics of acupuncture treatment using fMRI. We expect that the results of this study will provide valuable scientific evidence of acupuncture treatment for CRI.Clinical trial registration: Chinese Clinical Trial Registry, identifier ChiCTR2300070349: https://www.chictr.org.cn/showproj.html?proj=188677.

Clinical Observation on Therapeutic Effect of Electroacupuncture Combined with Diclofenac Sodium in Treatment of Acute Gouty Arthritis: A Randomized Controlled Study.

Objective: To observe the clinical effect of electroacupuncture (EA) combined with diclofenac sodium (DS) in the treatment of acute gouty arthritis (AGA). Methods: Patients with AGA were randomly divided into three groups: the EA + DS treatment group (i.e., EA + DS group), the low-dose DS treatment group (i.e., low-dose DS group), and the conventional-dose DS treatment group (i. e., conventional DS group). Patients in the low-dose DS group took 50 mg of DS sustained-release capsules once a day. Patients in the conventional DS group took 100 mg of DS sustained-release capsules once a day. Patients in the EA + DS group were treated with EA three times in 7 days combined with 50 mg of DS sustained-release capsules once a day. For all the three groups, 7 days were regarded as a course of treatment. Outcome indicators included pain visual analog scale (VAS), joint tenderness, joint swelling and activity limitation, and levels of inflammatory indicators (C-reactive protein (CRP)/white blood cells (WBC)/percentage of neutrophils (NE%)), level of serum uric acid (SUA), gout impact scale (GIS), and frequency of adverse reactions). Results: After a course of treatment, indicators regarding the VAS, joint tenderness, joint swelling, activity limitation, GIS, inflammatory indicators (CRP/WBC/NE%), and SUA were all improved (P < 0.05) with no adverse reactions in the EA + DS group. The EA + DS group performed better than the low-dose DS group in improving indicators regarding the VAS, joint tenderness, activity limitation, GIS, inflammatory markers (WBC/NE%), and SUA (P < 0.05). Similarly, the EA + DS group performed better than the conventional DS group in improving indicators regarding GIS, SUA, and adverse reactions (P < 0.05). Conclusion: EA combined with DS can improve AGA patients' joint pain and functional status, thus improving their quality of life. Moreover, this combined treatment can reduce the levels of inflammatory markers and SUA, leading to fewer adverse reactions in AGA patients.

[Mechanism and material basis of Sparganii Rhizoma and vinegar-processed Sparganii Rhizoma in treatment of hyperlipidemia based on network pharmacology].

The present study explored the effective components, functional targets, and mechanism of Sparganii Rhizoma(vinegar-processed Sparganii Rhizoma) in the treatment of hyperlipidemia based on network pharmacology and experimental verification. In the network pharmacology, the screening of active components, target prediction, and pathway enrichment analysis of Sparganii Rhizoma were carried out, followed by the comparison with targets and pathways related to hyperlipidemia. In the experimental verification, the hyperlipidemia model in rats was induced to detect hemorheological parameters and coagulation function. The liver index was observed by HE staining, and PCR technology was used to verify the results of the network pharmacological analysis. Compared with the model group, the Sparganii Rhizoma and vinegar-processed Sparganii Rhizoma groups showed decreased liver index(P<0.05), reduced liver lipid deposition, dwindled serum low-density lipoprotein cholesterol(LDL-c) level(P<0.05), diminished blood viscosity, and increased prothrombin time(PT), thrombin time(TT), and activated partial thrombin time(APTT)(P<0.05). As revealed by the PCR assay, Sparganii Rhizoma could affect LDL-c and high-density lipoprotein cholesterol(HDL-c) levels and reduce the inhibitory effect of cholesterol ester transporter by regulating the expression of Apol2, Apof, and Stab2, thereby treating hyperlipidemia. Vinegar-processed Sparganii Rhizoma could enhance triglyceride metabolism and cholesterol reversal by regulating the expression of Hmgcr, Hmgcs2, Abca1, Abcg1, Cyp7 b1, and Stab2. Compared with the Sparganii Rhizoma, the vinegar-processed one was potent in treating hyperlipidemia. The active components of Sparganii Rhizoma in the treatment of hyperlipidemia may be L-alpha-palmitin,(1S,2S)-1,2-bis(2-furyl)ethane-1,2-diol, cis-zimtsaeure, o-acetyl-p-cresol, sanleng, and 9-hexadecenoic acid. Based on the network pharmacology and experimental verification, this study preliminarily explored the potential active components and possible mechanism of Sparganii Rhizoma in the treatment of hyperlipidemia, which is expected to provide a certain basis for in-depth research on active components, mechanism, and clinical application.

Development of the Applied Mindfulness Process Scale as a Process Evaluation Measure for Mindfulness Practice in a Chinese Context.

With the rising popularity of mindfulness practice, it is necessary and crucial to evaluate mindfulness using comprehensive and objective measures. The instruments to assess mindfulness in China mainly evaluate mindfulness as a state or trait mode. Few process measures have been developed to clarify effective therapy benefits of the alterations obtained using mindfulness practice. Therefore, this study aims to adapt the Applied Mindfulness Process Scale (AMPS) into Mandarin and explore in detail the reliability and validity of this novel-translated measure. Following cross-cultural modification for original AMPS into Mandarin as per established guidelines, psychometric evaluation was performed on a cohort of 234 Chinese adults. Construct validity was analyzed through exploratory factor analysis (n = 115), together with confirmatory factor analysis (n = 119). Reliability was assessed by internal consistency together with test-retest reliability. Findings indicated that the internal consistency was high, with Cronbach's alpha being 0.936. The principal component analysis led to a three-factor structure that explained 67.374% of all variations. The three-factor model was consistent with the original scale model. Based upon confirmatory factor analyses, all fitting indices satisfied the standard, which showed a close fit to the data. Therefore, the newly multi-culturally modified AMPS has sufficient validity, test-retest reliability, together with internal consistency. Chinese AMPS may offer researchers and clinicians a psychometrically optimized tool for evaluating the application of mindfulness and change process within mindfulness-based interventions (MBIs) in Mainland China.
