A randomized controlled study on acupuncture for peri-operative pain after open radical prostatectomy.

OBJECTIVES: To evaluate the advantages of adding acupuncture to standard postoperative pain management for open radical prostatectomy (RP). MATERIALS AND METHODS: A randomized controlled trial (1:1:1) comparing routine postoperative analgesic care (control [CON]) vs the addition of press tack needle acupuncture (ACU) or press tack placebo acupressure (SHAM) for pain management after open RP was performed. A total of 126 patients were enrolled between February 2020 and April 2021. After open RP, the CON group received standard postoperative analgesia, the ACU group received long-term acupuncture with press tacks at specific points (P-6, Shenmen and SP-6) along with standard analgesia, and the SHAM group received placebo press tacks at the same acupuncture points alongside standard analgesia. The primary endpoint was postoperative pain measured on a numeric rating scale, the NRS-11, calculated as the area under the curve. The cumulative use of routine postoperative analgesics, time to first defaecation, and quality of life were analysed using the Kruskal-Wallis rank sum test, Fisher's exact test, and Pearson's chi-squared test. RESULTS: The ACU group reported significantly less postoperative pain compared to the SHAM (P = 0.007) and CON groups (P = 0.02). There were no significant difference in median (interquartile range) cumulative pain medication usage, time to first defaecation (CON: 37 [33, 44] h; SHAM: 37 [33, 42] h; ACU: 37 [33, 41] h; P > 0.9), or health status at discharge (EuroQol five-dimension, five-level general health assessment questionnaire: CON: 70 [65-83]; SHAM: 70 [60-80]; ACU: 70 [50-80]). CONCLUSION: Incorporating acupuncture into postoperative pain management can improve patient postoperative outcomes.

Effects of contralateral versus ipsilateral electroacupuncture for analgesia and rehabilitation after unilateral total knee arthroplasty: a randomized controlled trial.

PURPOSE: Total knee arthroplasty (TKA) is a treatment for advanced knee osteoarthritis. Since postoperative pain affects rehabilitation, this study aimed to determine whether electroacupuncture (EA) contralateral to the surgical site is more effective than ipsilateral EA or sham EA in terms of relieving postoperative pain and promoting post-TKA rehabilitation. METHODS: In this parallel, single-blind randomized controlled trial, 114 patients undergoing unilateral TKA were assigned to the contralateral EA (EA on the contralateral side + sham EA on the ipsilateral), ipsilateral EA (EA on the ipsilateral + sham EA on the contralateral side), or sham EA (sham EA on both sides) groups (n = 38 each). Treatment was performed once daily on postoperative days 1-3. The visual analog scale (VAS) scores, additional opioid doses via patient-controlled analgesia (PCA) pump, Hospital for Special Surgery (HSS) knee scores, active/passive range of motion (AROM/PROM), swelling around the knee joint, and Hamilton anxiety scale (HAMA) scores were used for postoperative evaluation. RESULTS: At 3 days postoperatively, the VAS scores, HSS scores, AROM/PROM, swelling around the knee, and HAMA scores in the contralateral EA and ipsilateral EA groups were significantly improved compared with baseline. In addition, VAS scores, HSS scores, PROM and swelling around the knee were significantly better in the contralateral and ipsilateral EA groups than in the sham EA group, but similar in the two true EA groups. Furthermore, PCA additional dose release was significantly higher in the sham EA group than in the two true EA groups (which did not significantly differ). At 10 days postoperatively, the HSS scores, AROM/PROM, and HAMA scores were better in the contralateral and ipsilateral EA groups than in the sham EA group, but similar in the two true EA groups. CONCLUSION: Contralateral EA is more effective than sham EA for treating postoperative pain following TKA, but has an analgesic effect similar to that of ipsilateral EA.

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.

Mechanotransduction in the urothelium: ATP signalling and mechanoreceptors.

The urothelium, which covers the inner surface of the bladder, is continuously exposed to a complex physical environment where it is stimulated by, and responds to, a wide range of mechanical cues. Mechanically activated ion channels endow the urothelium with functioning in the conversion of mechanical stimuli into biochemical events that influence the surface of the urothelium itself as well as suburothelial tissues, including afferent nerve fibres, interstitial cells of Cajal and detrusor smooth muscle cells, to ensure normal urinary function during the cycle of filling and voiding. However, under prolonged and abnormal loading conditions, the urothelial sensory system can become maladaptive, leading to the development of bladder dysfunction. In this review, we summarize developments in the understanding of urothelial mechanotransduction from two perspectives: first, with regard to the functions of urothelial mechanotransduction, particularly stretch-mediated ATP signalling and the regulation of urothelial surface area; and secondly, with regard to the mechanoreceptors present in the urothelium, primarily transient receptor potential channels and mechanosensitive Piezo channels, and the potential pathophysiological role of these channels in the bladder. A more thorough understanding of urothelial mechanotransduction function may inspire the development of new therapeutic strategies for lower urinary tract diseases.

Impact factors of Blastocystis hominis infection in persons living with human immunodeficiency virus: a large-scale, multi-center observational study from China.

BACKGROUND: Blastocystis hominis (Bh) is zoonotic parasitic pathogen with a high prevalent globally, causing opportunistic infections and diarrhea disease. Human immunodeficiency virus (HIV) infection disrupts the immune system by depleting CD4+ T lymphocyte (CD4+ T) cell counts, thereby increasing Bh infection risk among persons living with HIV (PLWH). However, the precise association between Bh infection risk and HIV-related biological markers and treatment processes remains poorly understood. Hence, the purpose of the study was to explore the association between Bh infection risk and CD4+ T cell counts, HIV viral load (VL), and duration of interruption in antiviral therapy among PLWH. METHODS: A large-scale multi-center cross-sectional study was conducted in China from June 2020 to December 2022. The genetic presence of Bh in fecal samples was detected by real-time fluorescence quantitative polymerase chain reaction, the CD4+ T cell counts in venous blood was measured using flowcytometry, and the HIV VL in serum was quantified using fluorescence-based instruments. Restricted cubic spline (RCS) was applied to assess the non-linear association between Bh infection risk and CD4+ T cell counts, HIV VL, and duration of interruption in highly active antiretroviral therapy (HARRT). RESULTS: A total of 1245 PLWH were enrolled in the study, the average age of PLWH was 43 years [interquartile range (IQR): 33, 52], with 452 (36.3%) being female, 50.4% (n = 628) had no immunosuppression (CD4+ T cell counts > 500 cells/µl), and 78.1% (n = 972) achieved full virological suppression (HIV VL < 50 copies/ml). Approximately 10.5% (n = 131) of PLWH had interruption. The prevalence of Bh was found to be 4.9% [95% confidence interval (CI): 3.8-6.4%] among PLWH. Significant nonlinear associations were observed between the Bh infection risk and CD4+ T cell counts (Pfor nonlinearity < 0.001, L-shaped), HIV VL (Pfor nonlinearity < 0.001, inverted U-shaped), and duration of interruption in HARRT (Pfor nonlinearity < 0.001, inverted U-shaped). CONCLUSIONS: The study revealed that VL was a better predictor of Bh infection than CD4+ T cell counts. It is crucial to consider the simultaneous surveillance of HIV VL and CD4+ T cell counts in PLWH in the regions with high level of socioeconomic development. The integrated approach can offer more comprehensive and accurate understanding in the aspects of Bh infection and other opportunistic infections, the efficacy of therapeutic drugs, and the assessment of preventive and control strategies.

A marginal structural model analysis for the effect modification by education on the association between cancer diagnosis history and major depressive symptoms: Findings from Midlife Development in the U.S. (MIDUS).

BACKGROUND: Limited research has employed a longitudinal approach to investigate the role of education level as an effect modifier on the relationship between cancer diagnosis history and the experience of major depressive disorder (MDD) with a nationally representative sample. METHODS: We harnessed data from three installments of the MIDUS Longitudinal study (n = 7108). A Marginal Structural Model facilitated the investigation of associations between a history of cancer diagnosis, MDD, and potential modifying effects of education level. Inverse probability weighting helped manage confounding factors. RESULTS: Findings indicated that a cancer diagnosis made one year prior was linked with 3.741 times greater odds of experiencing MDD (95 % CI: 1.411-9.918, p < 0.01). This connection was absent for diagnoses made two years earlier. Among individuals with education up to high school, a recent cancer diagnosis significantly increased the likelihood of MDD in the subsequent wave by 3.45 times (95 % CI: 1.31-9.08, p < 0.05). This pattern was not apparent among better-educated individuals. LIMITATIONS: As the exposure variable was dependent on self-reported questionnaires, recall bias could be a potential limitation. Moreover, unaccounted variables like genetic factors could introduce confounding. CONCLUSIONS: A recent cancer diagnosis, particularly among less educated individuals, correlated with an increased probability of MDD, while the impact was not observed for older diagnoses. These findings emphasize that the timing of a cancer diagnosis and education level need consideration in the mental health assessment of cancer survivors.

[Effects of electroacupuncture on the secretion function of ovarian cells and kisspeptin/kiss1r system in rats with polycystic ovarian syndrome].

OBJECTIVE: To observe the effects of electroacupuncture （EA） on hormone secretion function of ovarian granulosa cells and theca cells, as well as the expression changes of kisspeptin and kiss1r in rats with polycystic ovarian syndrome （PCOS）, so as to explore the mechanism of EA for relieving ovarian dysfunction in PCOS rats. METHODS: Forty-eight SD female rats were randomly divided into control group, model group, EA group and flutamide group, with 12 rats in each group. PCOS rat model was replicated with the gavage of letrozole （0.1 mg/mL, 10 mL•kg-1•d-1）. In the EA group, EA （2 Hz, 2 mA） was used to stimulate "Guanyuan" （CV4） for 20 min each time. In the flutamide group, flutamide solution （50 mg•kg-1•d-1） was administrated by gavage. The treatments were given once daily for 14 days in each group. After the modeling and treatment, the body and ovarian weights of the rats were measured, and the ovarian index was calculated. Using HE staining, the morphological changes of ovary were observed. ELISA was adopted to detect the contents of testosterone （T）, luteinizing hormone （LH） and estradiol （E2） in serum, the contents of E2 and T in the culture medium of ovarian granulosa cells and theca cells, as well as the content of kisspeptin in the ovarian tissue. The positive expression of kisspeptin in ovary was observed by immunohistochemical method, and the protein expression of its receptor kiss1r was detected by Western blot. RESULTS: Compared with the control group, the body and ovarian weights, ovarian index, the contents of T and LH in serum and that of T in the culture medium of theca cells, as well as the content and positive expression of kisspeptin in ovary were all increased （P<0.01, P<0.05）； and the content of E2 in the culture medium of granulosa cells was decreased （P<0.01） in the model group. When compared with the model group, in the EA and flutamide groups, the body and ovarian weights, ovarian index, the contents of T and LH in serum and that of T in the culture medium of theca cells, as well as the content and expression of kisspeptin in ovary were all decreased （P<0.01, P<0.05）； and the content of E2 in the culture medium of granulosa cells was increased （P<0.05, P<0.01）. CONCLUSION: EA regulates the serum sex hormone levels, the secretion function of the ovarian granulosa cells and theca cells, and the ovarian kisspeptin/kiss1r protein expression in PCOS rats, showing the similar effect as receptor blockade intervention. It is suggested that the improvement of EA in ovarian dysfunction of PCOS rats may be related to the kisspeptin/kiss1r system.

[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.

Comparative study of two different rat models of stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to compare the success rate and urodynamic characteristics of the rat model of stress Urinary incontinence established by ovariectomy at different times after vaginal dilation. METHODS: Eighty female rats were randomly divided into three groups: the control group (n = 20), model group A (n = 30), i.e., the animals received colpectasis and bilateral oophorectomy within 1 day; model group B (n = 30), i.e., the animals received bilateral oophorectomy 1 week after colpectasis. The sneeze test and urodynamics were tested. RESULTS: There was no significant difference between the model group A and the model group B (p > 0.05) in the sneeze test. The leak point pressure (LPP) of model groups A and B was lower than that of the control group (p < 0.05). The LPP value of model group A was lower than that of model group B (p < 0.05). There was no significant difference in maximum bladder capacity (MBC) between model group A and the control group (p > 0.05); the MBC value of model group B was lower than that of the control group and model group A (p < 0.05). CONCLUSIONS: Models of stress urinary incontinence in rats can be successfully established by both modeling methods. In terms of LPP, model groups A and B had lower values than the control group, and model group A had lower values than model group B. In terms of MBC, there was no difference between model group A and the control group, and model group B had lower values than the control group and model group A.

Reduced SARS-CoV-2 infection risk is associated with the use of Seven-Flavor Herb Tea: A multi-center observational study in Shanghai, China.

OBJECTIVE: Omicron, a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant, is responsible for numerous infections in China. This study investigates the association between the use of Seven-Flavor Herb Tea (SFHT) and the risk of SARS-CoV-2 infection to develop precise and differentiated strategies for control of the coronavirus disease 2019 (COVID-19). METHODS: This case-control study was conducted at shelter hospitals and quarantine hotels in China. A total of 5348 laboratory-confirmed COVID-19 patients were enrolled between April 1 and May 31, 2022, while 2190 uninfected individuals served as healthy controls. Structured questionnaires were used to collect data on demographics, underlying diseases, vaccination status, and use of SFHT. Patients were propensity-score-matched using 1:1 nearest-neighbor matching of the logit of the propensity score. Subsequently, a conditional logistic regression model was used for data analysis. RESULTS: Overall, 7538 eligible subjects were recruited, with an average age of [45.54 ± 16.94] years. The age of COVID-19 patients was significantly higher than that of uninfected individuals ([48.25 ± 17.48] years vs [38.92 ± 13.41] years; t = 22.437, P < 0.001). A total of 2190 COVID-19 cases were matched with uninfected individuals at a 1:1 ratio. The use of SFHT (odds ratio = 0.753, 95% confidence interval: 0.692, 0.820) was associated with a lower risk of SARS-CoV-2 infection compared to untreated individuals. CONCLUSION: Our findings suggest that taking SFHT reduces the risk of SARS-CoV-2 infection. This is a useful study in the larger picture of COVID-19 management, but data from large-sample multi-center, randomized clinical trial are warranted to confirm the finding.

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 electroacupuncture on the morphology of prostate and degranulation of mast cells in rats with chronic nonbacterial prostatitis].

OBJECTIVE: To observe the effect of electroacupuncture (EA) on the morphology of prostate and degranulation of mast cells in prostate of rats with chronic nonbacterial prostatitis (CNP). METHODS: Male SD rats were randomly divided into sham operation group, model group and EA group, with 8 rats in each group. CNP model was established by surgical castration combined with 17-ß estradiol injection once daily for 30 days. EA was applied to "Zhongji" (CV3), "Guanyuan" (CV4) and bilateral "Dahe" (KI12) for 20 min, once daily for 8 days. The mechanical pain threshold of scrotum skin area was tested before modeling, after modeling and after intervention. The pathological morphology of the prostate was observed by HE staining. Collagenous fiber was observed by Masson staining. The infiltration of mast cells was observed by toluidine blue staining. The contents of interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) in prostate were determined by ELISA. The protein expression levels of tryptase and transforming growth factor ß1 (TGF-ß1) in prostate were detected by Western blot. RESULTS: A normal appearance with little inflammatory cell infiltration was observed in the prostate of the sham operation group. Gland atrophy, epithelial destruction, hyperemia and edema, diffuse inflammatory cell infiltration and visible collagen fiber deposition were observed in prostate of the model group. The degree of infiltration of inflammatory cells and collagen fiber deposition were reduced in the EA group. Compared with the sham operation group, mechanical pain threshold was decreased (P<0.01), while the collagen volu-me fraction (CVF) of prostate, the degranulated rate of mast cells, the protein expression levels of tryptase and TGF-ß1, and the contents of IL-6 and TNF-α were increased (P<0.01) in the model group. Following EA intervention, compared with the model group, the mechanical pain threshold was increased (P<0.01), CVF of the prostate, the degranulated rate of mast cells, the protein expression levels of tryptase and TGF-ß1, and the contents of IL-6 and TNF-α were decreased (P<0.05, P<0.01) in the EA group. CONCLUSION: EA can relieve pain and reduce inflammation and fibrosis of prostate in CNP rats, which may be related to inhibiting the degranulation of prostate mast cells and down-regulating the expression of inflammatory factors and TGF-ß1.

Effects of electroacupuncture on the kisspeptin-gonadotropin-releasing hormone (GnRH) /luteinizing hormone (LH) neural circuit abnormalities and androgen receptor expression of kisspeptin/neurokinin B/dynorphin neurons in PCOS rats.

BACKGROUND: Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism, anovulation, and polycystic ovaries. Electroacupuncture (EA) can effectively improve hyperandrogenism and increase ovulation frequency in patients with PCOS. Pieces of suggest that androgen activity in the brain is associated with impaired steroid negative feedback in such patients. Studies have shown that EA regulated androgen receptor (AR) expression and local factor levels (such as anti-Müllerian hormone and inhibin B) in the ovary of PCOS rats. However, few studies have explored the effect of EA on androgen activity in the brain. OBJECTIVE: This study investigated the effect of EA on the kisspeptin-gonadotropin-releasing hormone (GnRH)/luteinizing hormone (LH) neural circuit and sex hormone receptor expression in the hypothalamus of PCOS rats. METHODS: PCOS signs were induced by letrozole administration, and the induced rats were treated with low-frequency EA at Guan Yuan acupoint (CV4). The effect of EA on PCOS-like signs was evaluated by observing changes in the body weight, ovarian quality, ovarian morphology, and serum sex hormone levels in rats. To explore the mechanism of the effect of EA on PCOS-like signs, the neuropeptide content of the kisspeptin-GnRH/LH neural circuit was assessed using enzyme-linked immunosorbent assay(ELISA); AR and estrogen receptor α (ERα) coexpression on kisspeptin/neurokinin B/dynorphin (KNDy) neurons was determined via triple-label immunofluorescence; and protein and mRNA expression of Kiss1, Ar, Esr1, and kisspeptin receptor (Kiss1r) was evaluated via western blotting and Reverse Transcription-Polymerase Chain Reaction (RT-PCR). RESULTS: The results revealed that the estrous cycle of rats in the EA treatment group recovered, and their body and ovary weight reduced; ovarian morphology improved; serum testosterone and LH levels significantly decreased; and kisspeptin, GnRH, and dynorphin levels in hypothalamic arcuate nucleus significantly decreased. Compared with controls, the number of AR/Kiss1-positive cells increased, number of ERα/Kiss1-positive cells decreased, and protein and mRNA expression of Kiss1, Ar, and Kiss1r significantly increased in PCOS rats. However, EA treatment reversed these changes and reduced the expression of Kiss1, Ar, and Kiss1r significantly. CONCLUSION: Improvement in the reproductive hallmarks of PCOS rats via EA may be achieved by regulating the kisspeptin-GnRH/LH circuit via androgen activity attenuation. Thus, the results provide an experimental basis for acupuncture as an adjuvant medical therapy on PCOS.

Effect of Electroacupuncture Added to Pelvic Floor Muscle Training in Women with Stress Urinary Incontinence: A Randomized Clinical Trial.

BACKGROUND: Pelvic floor muscle training (PFMT) is a first-line conservative therapy for stress urinary incontinence (SUI). Electroacupuncture (EA) has been used to treat SUI recently. OBJECTIVE: To compare the effectiveness of PFMT + EA versus PFMT + sham EA for SUI in women. DESIGN, SETTING, AND PARTICIPANTS: A prospective, multicenter, randomized, controlled clinical trial was conducted at four hospitals in China involving 304 women with SUI from May 20, 2014 to November 21, 2017. Data were analyzed from April 20 to December 21, 2018. INTERVENTION: Participants were randomized to receive 8 wk of PFMT+ EA (n = 154) or PFMT + sham EA (n = 150). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was the change in the amount of urine leakage measured on a 1-hr pad test. Student's t test, the χ2 test, and the Wilcoxon rank-sum test were used for data analysis. RESULTS AND LIMITATIONS: Among the 304 participants randomized, 286 completed the study. The mean age was 57.6 yr (standard deviation [SD] 8.9) for the PFMT + sham EA group and 57.2 yr (SD 9.1) for the PFMT + EA group. The mean urine leakage at baseline was 13.6 g for the PFMT + sham EA group and 13.9 g for the PFMT + EA group. After the 8-wk intervention, the PFMT + EA group had a greater decrease in mean urine leakage (-9.8 g) than the PFMT + sham EA group (-5.8 g) with a mean difference of 4.0 g (95% confidence interval [CI] 0.8-7.2). Significantly more patients experienced a ≥50% reduction in urine leakage and the mean number of incontinence episodes in 24 h in the PFMT + EA group than in the PFMT + sham EA group (26.3%, 95%CI 15.8-36.8%). The PFMT + EA group experienced better improvement in participant-reported SUI severity at 6 wk (p < 0.001) and 8 wk (p < 0.001) and self-evaluated therapeutic effects at 2-32 wk (p < 0.001) after the intervention. Lack of measurement of the amount of urine leakage during follow-up is a limitation. CONCLUSIONS: In this randomized clinical trial, 8-wk combined treatment with PFMT + EA led to a greater improvement in SUI symptoms and better outcomes than with PFMT + sham EA. PATIENT SUMMARY: We evaluated the effectiveness and safety of pelvic floor muscle training combined with electroacupuncture for stress urinary incontinence in women, Our results show that this is a promising therapeutic approach for the treatment of stress urinary incontinence.

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.

The rapid and efficient strategy for SARS-CoV-2 Omicron transmission control: analysis of outbreaks at the city level.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron (B.1.1.529) variant is highly transmissible with potential immune escape. Hence, control measures are continuously being optimized to guard against large-scale coronavirus disease 2019 (COVID-19) outbreaks. This study aimed to explore the relationship between the intensity of control measures in response to different SARS-CoV-2 variants and the degree of outbreak control at city level. METHODS: A retrospective study was conducted in 49 cities with COVID-19 outbreaks between January 2020 and June 2022. Epidemiological data on COVID-19 were extracted from the National Health Commission, People's Republic of China, and the population flow data were sourced from the Baidu migration data provided by the Baidu platform. Outbreak control was quantified by calculating the degree of infection growth and the time-varying reproduction number ([Formula: see text]). The intensity of the outbreak response was quantified by calculating the reduction in population mobility during the outbreak period. Correlation and regression analyses of the intensity of the control measures and the degree of outbreak control for the Omicron variant and non-Omicron mutants were conducted, respectively. RESULTS: Overall, 65 outbreaks occurred in 49 cities in China from January 2020 to June 2022. Of them, 66.2% were Omicron outbreaks and 33.8% were non-Omicron outbreaks. The intensity of the control measures was positively correlated with the degree of outbreak control (r = 0.351, P = 0.03). The degree of reduction in population mobility was negatively correlated with the Rt value (r = - 0.612, P < 0.01). Therefore, under the same control measure intensity, the number of new daily Omicron infections was 6.04 times higher than those attributed to non-Omicron variants, and the Rt value of Omicron outbreaks was 2.6 times higher than that of non-Omicron variants. In addition, the duration of non-Omicron variant outbreaks was shorter than that of the outbreaks caused by the Omicron variant (23.0 ± 10.7, 32.9 ± 16.3, t = 2.243, P = 0.031). CONCLUSIONS: Greater intensity of control measures was associated with more effective outbreak control. Thus, in response to the Omicron variant, the management to restrict population movement should be used to control its spread quickly, especially in the case of community transmission occurs widely. Faster than is needed for non-Omicron variants, and decisive control measures should be imposed and dynamically adjusted in accordance with the evolving epidemic situation.

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.

Effect of electroacupuncture on the intestinal microflora in rats with stress urinary incontinence.

Objective: To examine the effect of electroacupuncture on the urodynamics and gut microbiota of rats with stress urinary incontinence (SUI). Materials and methods: Thirty 2-month-old female Sprague-Dawley (SD) rats were randomly assigned to 4 groups: normal (N), model (M), nonacupoint electric acupuncture control (NAAC), and electroacupuncture (EA). An SUI rat model was established through vaginal balloon dilatation and bilateral oophorectomy. After various treatments, urodynamic tests were performed, and feces were collected. 16S rRNA sequencing analysis was used to investigate SUI-related changes in the intestinal flora. Results: After treatment, compared with those of the M group, the leak point pressure and maximum bladder capacity of the electroacupuncture groups increased (P<0.05). The species community compositions of the N and M groups differed at the genus level, and there were 15 differentially abundant bacterial genera (P<0.05). The Blautia proportion was increased by electroacupuncture treatment (P<0.05) and was significantly positively correlated with the electroacupuncture treatment of SUI (according to Spearman correlation analysis). Conclusion: Electroacupuncture treatment can improve signs of urine leakage in rats with SUI rats by increasing the leak point pressure and maximum bladder capacity. The enrichment of Blautia by electroacupuncture treatment enrichment may be related to SUI sign improvement.

Piezo channels in the urinary system.

The Piezo channel family, including Piezo1 and Piezo2, includes essential mechanosensitive transduction molecules in mammals. Functioning in the conversion of mechanical signals to biological signals to regulate a plethora of physiological processes, Piezo channels, which have a unique homotrimeric three-blade propeller-shaped structure, utilize a cap-motion and plug-and-latch mechanism to gate their ion-conducting pathways. Piezo channels have a wide range of biological roles in various human systems, both in vitro and in vivo. Currently, there is a lack of comprehensive understanding of their antagonists and agonists, and therefore further investigation is needed. Remarkably, increasingly compelling evidence demonstrates that Piezo channel function in the urinary system is important. This review article systematically summarizes the existing evidence of the importance of Piezo channels, including protein structure, mechanogating mechanisms, and pharmacological characteristics, with a particular focus on their physiological and pathophysiological roles in the urinary system. Collectively, this review aims to provide a direction for future clinical applications in urinary system diseases.
