Clinical study on improving the function of female bladder in controlling urine by acupuncture Zhibian (BL54) under ultrasound guidance.

OBJECTIVE: To observe the effect of acupuncture Zhibian (BL54) on the function of the bladder in controlling urine in women under ultrasound. METHOD: 74 healthy subjects were randomly divided into deep acupuncture group of 37 cases and shallow acupuncture group of 37 cases. Under the guidance of ultrasound, the two groups of subjects were acupunctured at bilateral BL54. The deep acupuncture group was acupunctured to the pudendal nerve, and the shallow acupuncture group was acupunctured to the superficial fascia. Ultrasound was used to observe the peak systolic velocity (PSV), time average maximum velocity (TAMX), end diastolic velocity (EDV), pulsation index (PI), resistance index (RI) of the pudendal arteries, and bladder volume of two groups of subjects before and after acupuncture. The anatomical hierarchical structure of bilateral BL54 and score of Chinese version of the Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS) of all subjects was measured. RESULT: After acupuncture, the PSV, TMAX of the pudendal artery, bladder volume, and the Score of C-MASS Scale in the deep acupuncture group were higher than in the shallow acupuncture group (P < 0.05). The RI of the pudendal arteries in the shallow acupuncture group decreased compared to before acupuncture (P < 0.05). CONCLUSION: Acupuncture at the BL54 can increase the blood flow velocity of the pudendal artery, improve the function of the bladder in controlling urine in women, and different depths of acupuncture will have different therapeutic effects.

Efficacy of Warm Acupuncture Therapy Combined with Kegel Exercise on Postpartum Pelvic Floor Dysfunction in Women.

INTRODUCTION AND HYPOTHESIS: The objective was to observe the clinical efficacy of warm acupuncture combined with Kegel exercise in treating postpartum pelvic floor dysfunction in women. METHODS: A total of 70 primiparous women with postpartum pelvic floor muscle (PFM) injury were randomly divided into a combination group (n = 35, receiving warm acupuncture at Zhibian (BL54) acupoint and Kegel exercise) and a sham control group (n = 35, receiving sham warm acupuncture and Kegel exercise). Both groups were treated three times a week for 4 consecutive weeks. The recovery of PFM strength and changes in Urethral Rotation Angle (URA), Bladder Neck Descent (BND), and Retrovesical Angle (RVA) in pelvic floor ultrasound reports, the scores of pelvic floor dysfunction-related questionnaires, and the efficacy of urinary incontinence treatment of the two groups were compared before and after treatment. RESULTS: After treatment, the recovery rates of type I and II PFM strength, pelvic floor ultrasound parameters, pelvic floor dysfunction-related scale scores, and urinary incontinence treatment efficacy in the combination group were significantly better than those in the sham control group (p < 0.05). CONCLUSION: Warm acupuncture combined with Kegel exercise can significantly improve PFM strength and promote the recovery of postpartum pelvic floor function in women.

Effect on serum metabolomics of rats with premature ovarian insufficiency by Zhibian (BL54) through Shuidao (ST28) acupuncture.

OBJECTIVE: To analyze the serum metabolic targets of the "Zhibian (BL54) through Shuidao (ST28)" acupuncture technique in cyclophosphamide (CTX)-induced premature ovarian insufficiency (POI) model rats and to elucidate the potential molecular mechanism of acupuncture in improving POI. METHODS: We used an intraperitoneal injection of CTX to establish the POI rat model (POI group) and compared serum hormone levels and ovarian histopathological changes to evaluate the effect of the Zhibian (BL54) through Shuidao (ST28) technique (ZS + POI group) on ovarian function. Then, nontargeted metabolomics was performed using rat serum by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS). RESULTS: After acupuncture intervention, the serum hormone levels and ovarian pathological morphology of POI rats were effectively improved. Moreover, UPLC-Q-TOF/MS results showed that the ZS + POI group showed a significant reversal of the levels of 6 differential metabolites. Among them, the levels of four serum metabolic markers, divanillyltetrahydrofuran ferulate, trans-ferulic acid, tryptamine, and neuraminic acid, increased significantly. Further analysis of biological effects showed that all metabolites were involved in the regulation of reproductive hormone levels and antioxidant and antiapoptotic effects. CONCLUSIONS: The "Zhibian (BL54) through Shuidao (ST28)" acupuncture method may improve the ovarian function of POI rats by regulating serum metabolite markers to exert antioxidant and antiapoptotic effects, which provides a theoretical basis for the clinical application of acupuncture in the treatment of POI.

[Effect of acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) on PI3K/AKT/FOXO3a pathway in mice with poor ovarian response].

OBJECTIVE: To observe the protective effect of acupuncture at "Zhibian" (BL 54) through "Shuidao (ST 28)" based on the PI3K/AKT/FOXO3a pathway in mice with poor ovarian response (POR), and to explore the possible mechanism of acupuncture in inhibiting ovarian granulosa cells apoptosis in POR. METHODS: A total of 45 mice with regular estrous cycles were randomly divided into a blank group, a model group and an acupuncture group, with 15 mice in each group. Mice in the model group and the acupuncture group were given triptolide suspension (50 mg•kg-1•d-1) by gavage for 2 weeks to establish POR model. After successful modeling, mice in the acupuncture group were given acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) for 2 weeks, once a day, 20 min each time. Ovulation induction was started the day after the intervention ended, and samples were taken from each group after ovulation induction. Vaginal smears were used to observe changes in the estrous cycle of mice. The number of oocytes retrieved, ovarian wet weight, final body weight, and ovarian index were measured. The levels of anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), estradiol (E2), and luteinizing hormone (LH) in serum were detected by ELISA. The morphology of ovarian tissue was observed by HE staining. The apoptosis of ovarian granulosa cells was detected by TUNEL staining. The mRNA expression of PI3K, AKT, and FOXO3a in ovarian tissue was detected by real-time fluorescence quantitative PCR. The protein expression of Bcl-2 associated X protein (BAX), caspase-3, phosphorylated phosphatidylinositol 3-kinase (p-PI3K), and phosphorylated protein kinase B (p-AKT) in ovarian tissue was detected by Western blot. RESULTS: Compared with the blank group, the rate of estrous cycle disorder in the model group was increased (P<0.01); compared with the model group, the rate of estrous cycle disorder in the acupuncture group was decreased (P<0.01). Compared with the blank group, the number of oocytes retrieved, ovarian wet weight, ovarian index, and final body weight in the model group were decreased (P<0.01); compared with the model group, the number of oocytes retrieved, ovarian index, and ovarian wet weight were increased (P<0.01, P<0.05), and there was no significant difference in final body weight (P>0.05) in the acupuncture group. Compared with the blank group, the serum levels of FSH and LH were increased (P<0.01), and the serum levels of AMH and E2 were decreased (P<0.01) in the model group; compared with the model group, the serum levels of FSH and LH were decreased (P<0.01, P<0.05), and the serum levels of AMH and E2 were increased (P<0.01, P<0.05) in the acupuncture group. Compared with the blank group, the number of normal developing follicles in ovarian tissue in the model group was decreased and the morphology was poor, while the number of atretic follicles increased; compared with the model group, the number, morphology, and granulosa cell structure of follicles in the acupuncture group improved to varying degrees, and the number of atretic follicles decreased. Compared with the blank group, the apoptosis rate of ovarian granulosa cells in the model group was increased (P<0.01); compared with the model group, the apoptosis rate of ovarian granulosa cells in the acupuncture group was decreased (P<0.01). Compared with the blank group, the FOXO3a mRNA expression and caspase-3 and BAX protein expression in ovarian tissue in the model group were increased (P<0.01), and the mRNA expression of PI3K and AKT and the protein expression of p-PI3K, p-AKT, and p-FOXO3a in ovarian tissue were decreased (P<0.01); compared with the model group, the mRNA expression of FOXO3a and protein expression of caspase-3 and BAX in ovarian tissue in the acupuncture group were decreased (P<0.05, P<0.01), and the mRNA expression of PI3K and AKT and the protein expression of p-PI3K, p-AKT, and p-FOXO3a in ovarian tissue were increased (P<0.01, P<0.05). CONCLUSION: Acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) could inhibit ovarian cell apoptosis, and improve ovarian function in POR mice, and its mechanism may be related to the regulation of key factors in the PI3K/AKT/FOXO3a pathway.

[Effect of penetrative needling of "Zhibian" (BL54) through "Shuidao" (ST28) on expression of TRAIL and its receptors in rats with premature ovarian insufficiency].

OBJECTIVE: To observe the effect of penetrative needling of "Zhibian" (BL54) through "Shuidao" (ST28) on the expressions of death receptor pathway-related protein tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its receptors, as death receptor 4 (DR4), death receptor 5 (DR5), decoy receptor 1 (DcR1) and decoy receptor 2 (DcR2) in premature ovarian insufficiency (POI) rats, so as to explore its mechanisms underlying improvement of POI. METHODS: Forty female SD rats were randomly divided into blank control, model, penetrative needling and medication (estradiol valerate) groups, with 10 rats in each group. The POI model was established by intraperitoneal injection of cyclophosphamide (D1: 50 mg·kg-1·d-1, D2 to D15: 8 mg·kg-1·d-1, for a total of 15 d). After successful modeling, the rats in the penetrative needling group received penetrative needling of BL54 through ST28, with the needle retained for 30 min, once a day for a total of 4 weeks. Rats of the medication group received gavage of estradiol valerate (0.09 mg·kg-1·d-1) once daily for 4 weeks. After the intervention, the content of serum follicles of stimulation hormone (FSH),lateinizing hormone (LH),estradiol (E2) and vascular endothelial growth factor (VEGF) were assayed using enzyme-linked immunosorbent assay, and histopathological changes of ovarian tissue and the number of follicles were observed under light microscope after H.E. staining. The expression levels of TRAIL, DR4, DR5, DcR1, DcR2, and Fas-associated death domain (FADD) in ovarian tissues were detected using quantitative real-time PCR, and the immunoactivity of ovarian TRAIL, DR4 and DR5 detected using immunohistochemistry. The body weight and the damp weight of ovary were measured for calculating the ovarian coefficient. RESULTS: Compared with the blank control group, the E2 and VEGF contents, ovarian coefficient, and the number of the primary, secondary and sinus follicles were significantly decreased (P<0.01) in the model group, whereas FSH and LH contents, the atretic follicle number, TRAIL, DR4 and DR5 immunoactivity, and the expression levels of TRAIL, DR4, DR5 and FADD mRNAs considerably increased in the model group (P<0.01). In comparison with the model group, the decrease of the VEGF content, ovarian coefficient, and the number of the primary, secondary and sinus follicles, and the increase of the atretic follicle number, TRAIL, DR4 and DR5 immunoactivity, and expression levels of TRAIL, DR4, DR5 and FADD mRNAs were reversed in both penetrative needling and medication groups (P<0.01, P<0.05). The number of primary follicles was significantly more in the medication group than in the penetrative needling group (P<0.01). CONCLUSION: Penetrative needling of BL54 and ST28 can improve ovarian weight and promote follicular development in POI rats, which may be associated with its function in down-regulating the expression of pro-apoptotic proteins TRAIL, DR4, DR5 and FADD of the death receptor pathway to inhibit apoptosis of ovarian granulosa cells.

[Effect of acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) on the expression of apoptosis-related factors in rats with premature ovarian insufficiency based on oxidative stress].

OBJECTIVE: To explore the possible mechanism of acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) on premature ovarian insufficiency (POI) from the perspective of oxidative stress. METHODS: Sixty female SD rats were randomly divided into a blank group, a model group, a sham acupuncture group, a medication group, and an acupuncture group, 12 rats in each group. Except the blank group, the rats in the remaining groups were intraperitoneally injected with cyclophosphamide to establish the POI model. After the model was successfully established, the rats in the acupuncture group were treated with acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28), with a depth of about 12 mm, and the needle was retained for 30 min; the acupuncture was given once a day, for a total of 4 weeks. The rats in the sham acupuncture group were treated with blunt-head needle to tap the skin surface of "Zhibian" (BL 54), without penetrating the skin, once a day for 4 weeks. The rats in the medication group were treated with estradiol valerate by gastric gavage for 4 weeks. After the intervention, the level of reactive oxygen species (ROS) in the ovarian tissue was detected by fluorescence probe; the expression of c-Jun N-terminal kinase (JNK), forkhead box O1 (FoxO1), tumor suppressor gene protein 53 (p53) and p53 up-regulated modulator of apoptosis (Puma) mRNA and protein in ovarian tissue were detected by real-time fluorescence quantitative PCR and Western blot. RESULTS: Compared with the blank group, the level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the model group were increased (P<0.01). Compared with the model group, the level of ROS and the expression of p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the sham acupuncture group were slightly reduced, but the difference was not statistically significant (P>0.05). The level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the acupuncture group and the medication group were reduced (P<0.01). CONCLUSION: Acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) could improve the level of oxidative stress, down-regulate the expression of apoptosis-related factors JNK, FoxO1, p53 and Puma induced by oxidative stress, and inhibit the premature failure of ovarian reserve function caused by apoptosis of ovarian granulosa cells in POI rats.

[Effect of "Zhibian" (BL 54)-to-"Shuidao" (ST 28) needle insertion on the expression of Fas/FADD/Caspase-8 of death receptor pathway in rats with primary ovarian insufficiency].

OBJECTIVE: To explore the effect of "Zhibian" (BL 54)-to-"Shuidao" (ST 28) needle insertion on the ovarian function in the rats with primary ovarian insufficiency (POI) and the potential effect mechanism based on the Fas/FADD/Caspase-8 of death receptor pathway. METHODS: Forty-eight female SD rats were randomly divided into a blank group, a model group, a medication group and an acupuncture group, with 12 rats in each group. Except in the blank group, the rats in the other groups were intraperitoneally injected with cyclophosphamide to establish the POI model. In the acupuncture group, after successful modeling, the intervention was given with "Zhibian" (BL 54)-to- "Shuidao" (ST 28) needle insertion, once daily, 30 min in each intervention; and the duration of intervention was 4 weeks. In the medication group, estradiol valerate tablets were administered intragastrically, 0.09 mg•kg-1•d-1, for 4 weeks. The general situation and the estrous cycle of the rats were compared among groups. Using ELISA, the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in the serum were detected. HE staining was adopted to observe the morphological changes of ovarian tissue of rats. The protein expression of Fas, FADD and Caspase-8 in ovarian tissue was detected with immunohistochemistry and Western blot. RESULTS: After modeling, except the rats of the blank group, the rats of the other groups had dry fur, lost hair, low spirits, reduced food intake, increased urination and loose stool. After intervention, the stool became regular gradually in the acupuncture group and the medication group. The percentage of estrous cycle disturbance was increased in the rats of the model group when compared with the blank group (P<0.01); in comparison with the model group, the percentages of estrous cycle disturbance were reduced in the acupuncture group and the medication group after intervention (P<0.01). When compared with the blank group, the body mass and E2 content in the serum were lower (P<0.01), the levels of FSH and LH in the serum and the protein expression levels of Fas, FADD and Caspase-8 were increased (P<0.01) in the model group. Compared with the model group, the body mass and E2 contents in the serum were higher (P<0.01), the levels of FSH and LH in the serum and the protein expression levels of Fas, FADD and Caspase-8 were reduced (P<0.01) in the acupuncture group and the medication group. CONCLUSION: "Zhibian" (BL 54)-to-"Shuidao" (ST 28) needle insertion can effectively improve the ovarian function of POI rats, and its effect mechanism may be related to regulating the serum sex hormone levels, reducing the expression of Fas, FADD and Caspase-8 in ovarian tissue and retarding apoptosis of ovarian cells.

OBJECTIVE: To observe effect of "Zhibian (BL 54) through Shuidao (ST 28)" acupuncture for quality of life of female patients with stress urinary incontinence. METHODS: A total of 90 female patients were randomly divided into an observation group and a control group, 45 cases in each group. The patients in the observation group were treated with "Zhibian (BL 54) through Shuidao (ST 28)" acupuncture method, and the patients in the control group were treated with non-permeable sham acupuncture at Zhibian (BL 54). The needles were retained for 30 min in both groups, once a day, and the treatment was totally given 10 times. The score of urinary incontinence quality of life questionnaire (I-QOL) was recorded before and after treatment and during the follow-up 1 month after treatment in the two groups, and the 1 h urine pad test and the 72 h urination diary card were used to evaluate the 1 h urine leakage and the 24 h urine leakage frequency of the two groups. RESULTS: After treatment and during follow-up, the I-QOL scores in the observation group were higher than those before treatment (P<0.05), and were higher than those in the control group (P<0.05). After treatment and during follow-up, the 1 h urine leakage and the 24 h urine leakage frequency in the observation group were lower than those before treatment (P<0.05), and less than those in the control group (P<0.05). CONCLUSION: Acupuncture of "Zhibian (BL 54) through Shuidao (ST 28)" can improve the quality of life of female patients with stress urinary incontinence, and improve the volume and frequency of urine leakage.

[Effects on urinary retention after spinal cord injury treated with acupuncture at Zhibian (BL 54) and Shuidao (ST 28) with elongated needle].

OBJECTIVE: To explore the clinical effects of acupuncture with elongated needle on urinary retention after spinal cord injury. METHODS: A total of 66 patients with urinary retention after spinal cord injury were randomized into an elongated needle group (34 cases) and a filiform needle group (32 cases). In both of the groups, the routine orthopedic treatment and the bladder function training were adopted. Additionally, in the elongated needle group, the acupuncture at Zhibian (BL 54) and Shuidao (ST 28) was used with the elongated needle. In the filiform needle group, the acupuncture with filiform needle was used at Zhibian (BL 54) and Shuidao (ST 28). In both of the groups, acupuncture treatment was provided once every two days, for 2 months consecutively. Separately, before treatment and after 1, 2 month treatment, the residual urine volume, urodynamic parameters (bladder capacity, peak urinary flow rate and bladder pressure) and safety indicators were observed in the patients of the two groups. The clinical therapeutic effects were compared between the two groups. RESULTS: As compared with the results before treatment, the residual urine volume was reduced obviously (all P<0.01), bladder capacity, peak urinary flow rate and bladder pressure were improved obviously (all P<0.01) after 1, 2 month treatment in the two groups. After 1, 2 month treatment, the residual urine volume in the elongated needle group was lower than the filiform needle group (both P<0.01). The improvements in bladder capacity, peak urinary flow rate and bladder pressure in the elongated needle group were superior to the filiform needle (all P<0.01). The total effective rate was 94.1% (32/34) in the elongated needle group, higher than 71.9% (23/32) in the filiform needle group (P<0.01). During treatment, there was no damage of kidney function, no fainting or broken needle happened in the two groups. CONCLUSION: Acupuncture with elongated needle achieves the significant effects on urinary retention after spinal cord injury. This therapy is better than acupuncture with filiform needle and safe in operation.

The study of traditional Chinese medical elongated-needle therapy promoting neurological recovery mechanism after spinal cord injury in rats.

ETHNOPHARMACOLOGICAL RELEVANCE: Acupuncture is a key part of traditional Chinese medicine, shown to induce favorable neuroplasticity for injuries in the central and peripheral nervous systems. Recent studies report elongated needle therapy (ENT) with BL54 and ST28 may restore acute spinal cord injury (ASCI). However, the precise mechanism for this has not been elucidated. AIM OF THE STUDY: In our current study, we investigated the effects of ENT on inflammation and neuronal apoptosis induced by ASCI, and whether PI3K/Akt and MAPK/ERK signaling pathways are involved in the ENT restoration effect. MATERIALS AND METHODS: Rat models of moderate SCI were established in accordance with the modified Allen's method and were treated with ENT continuously for 7 days. Spontaneous activities were evaluated by the Basso Beattie and Bresnahan locomotor scale. Levels of inflammatory cytokines, such as tumor necrosis factor alpha, interleukin-6, IL-1ß, and nuclear factor kappa-ß, were determined by enzyme-linked immunosorbent assay. Cell apoptosis was examined by the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The proportions of cells with positive Bcl-2 and Bax expression were determined by immunohistochemical assays, whilst the expression profiles of p-AKT and p-ERK in spinal cord tissues were evaluated by western blotting. Furthermore, the expression profiles of Cytochrome-C (Cyt-C) and caspase-3 in vivo were analyzed by reverse transcription polymerase chain reaction. The potential inhibitory effects downstream of the Akt and ERK signaling pathways were examined by administration of specific inhibitors LY294002 and PD98059 in vivo. RESULTS: As indicated by this study, inflammation as well as PI3K/Akt- and MAPK/ERK signaling pathway-mediated neuronal apoptosis were involved in the course of SCI in rats. The neuro-protective effect of ENT was associated with reduced Bax protein-positive neurons and increased Bcl-2 protein-positive neurons. ENT enhanced recovery of rat activities. Activation of p-Akt and p-ERK in the PI3K/Akt and MAPK/ERK signaling pathways, inhibited expression of the critical component Cyt-C. Cyt-C is required for the mitochondrial apoptosis pathway and cascade of caspase-3, which is involved in activation of neuronal apoptosis through down-regulation of Bax protein and up-regulation of Bcl-2, as determined by TUNEL. The administration of PI3K/Akt and MAPK/ERK signaling pathway specific inhibitors, LY294002 and PD98059, suppressed expression of both p-Akt and p-ERK. CONCLUSION: ENT with BL54 and ST28 points can promote the recovery of ASCI. And the neuro-protective effect of ENT during the restoration of SCI may be associated with the suppression of both inflammation and activation of PI3K/Akt and MAPK/ERK signaling pathways, resulting from down-regulation of Bax protein, up-regulation of Bcl-2, and inhibition of the mitochondrial apoptosis pathway.
