Antipruritic effects of electroacupuncture on morphine-induced pruritus model mice through the TLR2/4-MyD88-NF-κB pathway.

Pruritus is one of the common side effects of intrathecal or epidural injection of opioids. The aim of this study was to test the antipruritic effect of acupuncture and its possible mechanism. We used electroacupuncture (EA), toll-like receptor (TLR)2/4 antagonist sparstolonin B (SsnB), and TLR2/4 agonist peptidoglycan (PGN) to precondition female wild-type BALB/c mice, and then prepared a morphine-induced pruritus model. The mRNA and protein expression levels of TLR2, TLR4, MyD88, and NF-κB were detected by RT-PCR and western blotting. The contents of interleukin (IL)-1, IL-6, IL-12, IL-10, and tumor necrosis factor-α in serum were measured by ELISA assays. Flow cytometry was performed to analyze the ratio of M1-phenotype to M2-phenotype macrophages. Our results showed that EA preconditioning improved pruritus; reduced the expressions of TLR2, TLR4, MyD88, and NF-κB both at the mRNA and protein levels (P<0.05); reduced the expression of proinflammatory cytokines IL-1, IL-6, IL-12, and tumor necrosis factor-α; and increased the expression of anti-inflammatory cytokine IL-10 (P<0.05). EA promoted M2-phenotype macrophage differentiation. Moreover, these results showed no significant difference between the SsnB group and the EA+SsnB group (P>0.05), but showed a significant difference between the PGN group and the EA+PGN group (P<0.05). Therefore, we propose that EA may be involved in the remission of pruritus in morphine-induced pruritus model mice through the TLR2/4-MyD88-NF-κB pathway. EA is a potential therapeutic treatment for pruritus.

Acupuncture for preventing complications after radical hysterectomy: a randomized controlled clinical trial.

We aimed to investigate the preventive effects of acupuncture for complications after radical hysterectomy. A single-center randomized controlled single-blinded trial was performed in a western-style hospital in China. One hundred and twenty patients after radical hysterectomy were randomly allocated to two groups and started acupuncture from sixth postoperative day for five consecutive days. Sanyinjiao (SP6), Shuidao (ST28), and Epangxian III (MS4) were selected with electrical stimulation and Zusanli (ST36) without electrical stimulation for thirty minutes in treatment group. Binao (LI14) was selected as sham acupuncture point without any stimulation in control group. The main outcome measures were bladder function and prevalence of postoperative complications. Compared with control group, treatment group reported significantly improved bladder function in terms of maximal cystometric capacity, first voiding desire, maximal flow rate, residual urine, and bladder compliance, and decreased bladder sensory loss, incontinence, and urinary retention on fifteenth and thirtieth postoperative days. Treatment group showed significant advantage in reduction of urinary tract infection on thirtieth postoperative day. But no significant difference between groups was observed for lymphocyst formation. By improving postoperative bladder function, early intervention of acupuncture may provide a valuable alternative method to prevent bladder dysfunctional disorders and urinary tract infection after radical hysterectomy.

Clinical observation on the acupuncture treatment in patients with urinary retention after radical hysterectomy.

OBJECTIVE: To observe the acupuncture therapy effect on the urinary retention after radical: hysterectomy. METHODS METHODS: Eighty cases of urinary retention after radical hysterectomy were randomly assigned to: the treatment group and control group according to the random number table method, 40 cases in each group. From the 15th day post operation, the patients in the two groups started to be treated and 7 days as a course with 5 days treatment and 2 days interval. The treatment group applied acupuncture with modalities of common needling on Zusanli (ST36) bilaterally, electroacupuncture on Sanyinjiao (SP6), Shuidao (ST28), and Scalp Reproduction Area bilaterally, moxibustion on Shenque (CV8). The control group applied acupoint injection with vitamin B B12 12, and Sanyinjiao and Zusanli were selected. Take turns on both sides. The courses for the recovery, of bladder function and residual urine volume for those who had voluntary micturition more than 200 mL after the first and second course of treatment were compared between the two groups. RESULTS: Within 1 course and 2: courses of treatment, the patients with bladder function recovery in the treatment group were 21 (21/40) and 36 (36/40), and those in the control group were 12 (12/40) and 29 (29/40), both with a significant difference (P<0.05). After the first course and second course, residual urine volume for those who had voluntary micturition more than 200 mL in the treatment group was 91.7 ± 17.5 mL and 93.5 ± 15.5 mL, in the control group 102.4 ± 13.7 mL and 102.5 ± 15.7 mL, both with a significant difference (P<0.05). CONCLUSIONS: Combination of acupuncture: modalities was better than acupoint injection for the recovery of bladder function in urinary retention after radical hysterectomy. It would shorten the course of treatment and get a better recovery, decrease urinary retention cases of refractoriness, and extending the treatment could raise the healing rate of urinary retention.

[Effects of electroacupuncture on urinary bladder function after radical hysterectomy].

OBJECTIVE: To observe the effect of electroacupuncture on recovery of urinary bladder function after radical hysterectomy. METHODS: One hundred and ten cases were randomly divided into an electroacupuncture (EA) group and a control group, 55 cases in each group. In the control group, the urinary tube was placed and kept with routine method and the urinary bladder was rinsed, and from the eighth day the abdomen was radiated with TDP, 30 min each day, for 5 days. In the EA group, on the basis of treatment in the control group EA was given at Sanyinjiao (SP 6), Zusanli (ST 36), Waiguan (TE 5), Shuidao (ST 28), Guilai (ST 29), etc. from the eighth day to twelfth day after operation. The recovery time of urinary bladder function after radical hysterectomy, urine dynamic indexes and hospitalization days were compared between the two groups. RESULTS: The cases of the bladder function recovery, retention of urine, urinary incontinence were 51(51/55), 4(4/55), 0 on the 14 th day after operation and 53(53/55), 2(2/55), 0 on the 28 th day in the EA group, and 27(27/55), 25(25/55), 3(3/55) on the 14 th day and 43(43/55), 11(11/55), 1(1/55) on the 28th day in the control group, respectively, with a very significant difference between the two groups (P < 0.01); the EA group in residual urine volume, bladder volume, mean urinary flowing rate was better than the control group on the 14 th day after operation (P < 0.01 or P < 0.05); the hospitalization days after operation was (21.1 +/- 3.3) days in the EA group and (25.5 +/- 3.5) days in the control group, the former being shorter than the later (P < 0.01). CONCLUSION: EA can promote recovery of bladder function, shorten the keeping time of urinary tube after radical hysterectomy, which is benefit to decreasing incidence rate of urinary system infection and shortening hospitalization days.

[The effect of gengnianningshentang on treating 72 patients with female climacteric syndrome of fever due to yin-deficiency].

OBJECTIVE: To observe the clinical effect of gengnianningshentang on the treatment of the climacteric syndrome of fever due to yin-deficiency. METHODS: 108 patients with climacteric syndrome of fever due to yin-deficiency were divided randomly into treatment group (76 cases)and control group (32 cases). Treatment group was treated by gengnianningshentang, and control group was treated by Vitamin E for 3 months. Level of serum E2, LH and FSH were determined, while the variation of symptom scores of climacteric syndrome was observed. RESULTS: Level of serum E2 in treatment group increased significantly and serum LH and FSH decreased significantly after treatment (p < 0.01). The post treatment total scores of climacteric syndrome in the treament group were significantly improved (p < 0.01). CONCLUSION: Gengnianningshentang can significantly improve the levels of E2, FSH and LH, and climacteric syndrome in patients of fever due to yin-deficiency. The total effect of gengnianningshentang is much better than western medicine.
