Acupuncture Versus Biofeedback for Treatment of Functional Anorectal Pain.

BACKGROUND/AIMS: Functional anorectal pain is one of several types of functional anorectal disorders. In this study, we compared the effectiveness of acupuncture (intervention) and biofeedback (control) as treatment for patients with functional anorectal pain. MATERIALS AND METHODS: This prospective, single-center, randomized, and comparative study examined 68 patients with functional anorectal pain who were recruited from June 2017 to January 2019 at the Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine. Patients were randomly assigned to receive acupuncture or biofeedback. Patients in the acupuncture group received acupuncture at Zhongliao (BL33), Xialiao (BL34), Ganshu (BL18), Shenshu (BL23), and Dachangshu (BL25). Patients in the biofeedback group received pelvic floor biofeedback therapy, consisting of Kegel pelvic floor muscle training and electrical stimulation. Patients in both groups received 20 treatments over 4 weeks. The primary outcome was pain score on a visual analog scale, and the secondary outcomes were results from the MOS 36-item short-form health survey (SF-36) quality of life questionnaire, the self-rating depression scale, and the self-rating anxiety scale. RESULTS: Visual analog scale pain scores significantly decreased in both of the groups with treatment (both P < .01). The final visual analog scale score was significantly lower in patients with pelvic floor dyssynergia who were treated with biofeedback (1.40 ± 0.97 vs. 5.30 ± 1.70) (P < .05). The 2 groups had similar decreases in self-rating depression scale and self-rating anxiety scale scores. Intriguingly, the acupuncture group had better mental health outcomes (P <.05). CONCLUSION: Both acupuncture and biofeedback therapy reduced the pain of patients with functional anorectal pain. Biofeedback provided more relief in patients with pelvic floor dyssynergia, and acupuncture provided greater improvements in mental health status.

Ding's herbal enema treats dextran sulfate sodium-induced colitis in mice by regulating the gut microbiota and maintaining the Treg/Th17 cell balance.

Ding's herbal enema (DHEP) is a traditional Chinese medicinal therapy that has been used to treat ulcerative colitis (UC) in China. The present study determined the molecular mechanism of the effect of DHEP in UC treatment. C57BL/6J mice were treated with 3.5% (w/v) dextran sulfate sodium (DSS) for 7 days to establish an animal model of colitis. The mice were divided into five groups (n=5): Control, vehicle, DHEP, mesalazine and ß-sitosterol. After oral administration for 7 days, the body weight, disease activity index, histopathology and inflammatory factors were analyzed. The fractions of CD4+Foxp3+ regulatory T (Treg) cells and CD4+IL-17A+ T helper (Th) cells were determined by flow cytometry. Gut microbiota composition was analyzed by next-generation sequencing. The results revealed that DHEP and ß-sitosterol could significantly alleviate the symptoms of DSS-induced UC. Furthermore, the levels of IL-6, cyclooxygenase-2, TNF-α and p65 were reduced after administration of DHEP. Additionally, the data indicated that DHEP could increase the abundance of seven operational taxonomic units (OTUs) and decrease the abundance of 12 OTUs in the gut microbiota. The content of short-chain fatty acids in the colon remodeled the balance of Treg/Th17 cells in DSS-induced UC in mice. The present study preliminarily defined the mechanism of action of DHEP in UC that may be associated with the regulation of the gut microbiota composition, and maintenance of the balance between Treg and Th17 cells. Furthermore, ß-sitosterol exhibited the same effects with DHEP and it could be a possible substitute for DHEP in UC treatment.

[Symptom distribution of female pelvic floor dysfunction patients with constipation as chief complaint].

OBJECTIVE: To observe the multiple symptom distribution, severity and quality of life of female pelvic floor dysfunction(FPFD) patients with constipation as chief complaint. METHODS: One hundred FPFD patients with constipation as chief complaint from Speciaty Outpatient Clinic, Pelvic Floor Center of Nanjing Municipal Hospital of Traditional Chinese Medicine between September 2015 and February 2017 were retrospectively enrolled in this study. A comprehensive medical history questionnaire survey and systematical evaluation of severity and quality of life of these patients with constipation was conducted. Constipation scoring system scale (CSS) and patient-assessment of constipation quality of life questionnaire (PAC-QOL) were applied to evaluate the constipation. Other scales included: (1)pain visual analogue scale (VAS) and short form-36 questionnaire (SF-36): if combined with chronic functional anal rectal pain; (2) international consultation on incontinence questionnaire-short form (ICIQ-SF) and urinary incontinence quality of life questionnaires (I-QOL):if combined with urinary incontinence; (3) fecal incontinence severity score scale (Wexner-FIS) and fecal incontinence quality of life questionnaire (FI-QOL):if combined with fecal incontinence. RESULTS: The mean age of 100 FPFD patients was (57.9±13.9) (24-89) years and the mean disease course was (7.0±8.2)(0.5-40.0) years. Seventy-five cases (75%) were complicated with anal pain, 70 with urinary incontinence, 37 with rectocele, 19 with nocturia, 11 with urinary frequency, 10 with defecation incontinence. Complication with only one symptom was observed in 20 cases (20%), and with two or more symptoms was observed in 80 cases (80%). Pelvic floor relaxation syndrome patients were dominant (58 cases, 58%). The severity of constipation (CSS) was 6-22 (13.89±3.79) points and the quality of life (PAC-QOL) was 45-133 (87.13±18.57) points in FPFD patients. VAS and SF-36 of patients combined with chronic functional anal rectal pain were 1-8 (3.0±1.9) points and 14.4-137.0(71.5±31.4) points respectively. ICIQ-SF and I-QOL of patients combined with urinary incontinence were 1-17 (6.1±3.6) points and 52-110 (90.0±15.8) points respectively. Wexner-FIS and FI-QOL of patients combined with fecal incontinence were 1-11 (4.4±3.0) points and 52-116 (83.4±23.3) points respectively. CONCLUSIONS: The symptoms of FPFD patients with constipation as chief complaint are complex. They are mainly complicated with anal diseases, then urinary incontinence, and mostly with more than 2 symptoms. Their quality of life is poor.

[Efficacy analysis of acupuncture with biofeedback in the treatment of patients with functional anorectal pain].

OBJECTIVE: To observe the short- and long-term efficacy of acupuncture combined with biofeedback in the treatment of functional anorectal pain (FARP). METHODS: Clinical data of 142 patients who met the functional gastrointestinal disorders and functional anorectal pain based on criteria of Rome III( undergoing acupuncture with biofeedback therapy from August 2010 to November 2015 in Pelvic Floor Center of The Third Affiliated Hospital of Nanjing University of Chinese Medicine were retrospectively analyzed. Telephone and outpatient clinic recheck were used as standard follow-up. The clinical effect of short-term and long-term data collected from the disease-based database was evaluated with visual analogue pain scale (VAS) (0-10 points), short form health survey questionnaire (SF-36) (0-148 points). The overall satisfaction and effectiveness (VAS was >30%) were evaluated at the end of treatment (short-term) and during follow-up (long-term). RESULTS: The effective follow-up data were obtained from 71.1%(101/142) of patients and the median follow-up time was 28(3-67) months. The VAS of 101 cases was 6.09±1.78, 1.99±1.89 and 3.55±2.60 before treatment, at the end of treatment and during follow-up respectively. Though the VAS during follow-up was higher than that at the end of treatment, but still significantly lower than that before treatment(P<0.05). The SF-36 score of 31 patients was 82.0±16.9, 94.0±15.1 and 88.1±15.3 before treatment, at the end of treatment and during follow-up respectively. Though the SF-36 score during follow-up was lower compared to at the end of treatment, but still significantly higher compared to before treatment (P<0.05). The effective rates were 85.9%(122/142) at the end of treatment and 75.2%(76/101) during follow-up, and the satisfactory rates were 92.3%(131/142) and 84.2%(85/101), respectively. CONCLUSION: Acupuncture with biofeedback has significant short-term and long-term efficacy in treating functional anorectal pain, and its degree of satisfaction is high.

[Variation of Locations of Baliao Acupoints in 290 Volunteer Subjects Analyzed by Using Computed Tomography-aided Three-dimensional Reconstruction Technique].

OBJECTIVE: To observe the variation of sacral vertebrates and foramen involving the bilateral Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33) and Xialiao (BL 34, Baliao acupoints), so as to provide an anatomic basis of acupoint needling in clinical practice. METHODS: A total of 290 patients[161 men and 129 women, mean age and standard devia-tion, (63.6±13.3)years old and (59.5±13.3) years old, respectively] with intact pelvic structure were recruited in the present study. Computed tomography (CT) scans of intact pelves were taken using a SOMATOM Definition AS 128 and the acquired signals were imported into Siemens Syngo Inspace platform for 3 D reconstruction, followed by identification, classification and analysis of the variation of sacral foramen (Baliao acupoint). RESULTS: The total variation rate of posterior sacral foramen (Baliao acupoint) was 20.34%(59/290). The detected three types of variation were sacral vertebrae number variation (4 sacral vertebraes, 6 sacral vertebraes), fusion variant (lumbosacral fusion, sacrococcygeal fusion, lumbosacral & sacrococcygeal fusion, and lumbosacral fusion & S 4 variation) and mixed type. CONCLUSIONS: Variations of sacral vertebrae including the number and fusion exist in the human body, suggesting an increase of the difficulty of acupoint needling. Since posterior iliac spine does not change generally, it is recommended to be used as a reference point for locating the Baliao acupoint.

[Observation on effect characteristics of electroacupuncture for different types of functional constipation].

OBJECTIVE: To explore the differences of electroacupuncture (EA) on onset time and symptom improvement for treatment of different types of functional constipation. METHODS: Thirty-eight cases of constipation were selected, including 9 cases of constipation-predominant irritable bowel syndrome (IBS-C), 10 cases of slow transit constipation (STC), 10 cases of pelvic floor dyssynergia (PFD) and 9 cases of inadequate defecatory propulsion (IDP). The electroacupuncture was applied at Tianshu (ST 25), Fujie (SP 14), Shenshu (BL 23), Dachangshu (BL 25) and so on in abdominal and lumbosacral area, 5 times per week, 10 times as a treatment course. The onset time, score of clinical symptoms of constipation and improvement of every symptom in each group were compared. RESULTS: (1) The onset time was (1.78 +/- 0.83) days in IBS-C type, (3.11 +/- 1.90) days in IDP type, (4.10 +/- 1.85) days in STC type and (4.30 +/- 2.00) days in PFD type, indicating statistical differences between IBS-C type and STC type, IBS-C type and PFD type (both P < 0.05). (2) Compared before the treatment, the total scores of symptoms on the onset day in each group were all improved (P < 0.05, P < 0.01), and score of IBS-C type was superior to the rest 3 types (P < 0.05, P < 0.01). (3) EA improved desire to defecate or frequency of defecation in each type (P < 0.05, P < 0.01), in which both were improved in STC type and PFD type, and the improvement of defecation frequency was more significant in STC type (P < 0.01). EA relieved unsmooth defecation or pendant-expansion feeling in each type (all P < 0.05), in which both were improved in IBS-C type (both P < 0.05). EA relieved abdominal distension and pain in IBS-C type, STC type and PFD type (all P < 0.05), while its effects were not obvious on defecation difficulty, defecation time and defecation texture (all P > 0.05). CONCLUSION: The electroacupuncture for treatment of 4 types of constipation is characterized by rapid onset; the improved symptoms are not identical in the electroacupuncture treatment plan for each type of defecation; the main improvement of symptoms are lied on desire to defecate and frequency of defecation, unsmooth defecation or pendant-expansion feeling and abdominal distension and pain. Meanwhile the improvements of defecation texture, defecation difficulty and defecation time were not signi-ficant.

[Study on the measurement and locating of Baliao points (eight sacral foramina)].

OBJECTIVE: To seek the problems of position, measuring and locating methods of Baliao points (posterior sacral foramina) in modern researches. METHODS: Using Baliao (eight sacral foramina), Shangliao(BL 31), Ciliao(BL 32), Zhongliao(BL 33), Xialiao(BL 34), Dihoukong (posterior sacral foramina), Dikong (sacral foramina) and Digu(sacrum) as the key words, literature in the database of the CNKI from 1957 to 2012 were re trieved and analyzed. RESULTS: Problems were found in the past researches including limited numbers of relative literature, disunity of the measurement targets, complicated terms of indices, disunity of the starting and ending point of measurement, unclear weight of indices, deviation of results, lacking of combination with clinical practice and variety of locating methods. CONCLUSION: Position of Baliao points (eight sacral foramina) are clear. However, the locating methods are blurred and vary a lot. Study on living body has more significance for measurement and researches. Factors of gender, body weight, height and childbearing should also be taken into consideration. Therefore, it is necessary to find a more accurate and easier way of locating.

[Influence of microsatellite instability on survival of patients with sporadic colorectal cancer in China].

OBJECTIVE: To investigate the role of microsatellite instability(MSI) in Chinese sporadic coloretal cancer. METHODS: A total of 146 patients with colorectal cancer were treated surgically from August 2004 to September 2006 in the Third Affiliated Hospital of Nanjing University of Traditional Chinese Medicine. Data were collected prospectively. Univariate and multivariable analyses were performed for parameters such as age, gender, tumor location, differentiation, MSI, tumor type, lymph node metastasis, TNM stage, and survival. RESULTS: Follow-up was available in 134 patients including telephone call and office visit. MSI(P=0.029), tumor type(P=0.000), TNM stage(P=0.000) were independently associated with survival on Cox regression model. There were 26 patients with MSI, and the 1-, 3-, and 5-year survival rates were 100%, 92.3%, and 92.3%, respectively. The remaining 108 patients had microsatellite stable tumor, and the 1-, 3-, and 5-year survival rates were 96.3%, 72.2%, and 63.5%, respectively. The difference was statistically significant(P=0.016). CONCLUSION: Microsatellite instability is an important factor associated with patient survival in Chinese sporadic colorectal cancer.

[Tea polyphenol inhibits colorectal cancer with microsatellite instability by regulating the expressions of HES1, JAG1, MT2A and MAFA].

OBJECTIVE: To investigate the mechanism of tea polyphenol in inhibiting microsatellite instability (MSI) of colorectal cancer. METHODS: Using LoVo cells and SW480 cells treated with aqueous solution of tea polyphenol, cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) method, changes in microsatellite sequences were detected by genescan method and changes in gene expression of LoVo cells were detected by illumina expression arrays and quantitative real-time polymerase chain reaction (PCR). RESULTS: The proliferation inhibition rates of LoVo and SW480 cells treated with tea polyphenol increased with the increasing of drug concentration and showed an increasing tendency with time. The proliferation inhibition rate of LoVo cells with tea polyphenol was higher than that of SW480 cells, and there was a significant difference in the proliferation inhibition rates at 24 h, 72 h and one week. The microsatellite sequence of LoVo cells treated with tea polyphenol remained stable. The gene expression arrays and quantitative real-time PCR suggested that tea polyphenol inhibited the gene expressions of MT2A, MAFA, HES1 and JAG1 nearly two-fold over controls. It was also found that tea polyphenol inhibited the BAX and p38 genes with a more than two-fold difference but did not significantly inhibit the nuclear factor-κB pathway. CONCLUSION: Tea polyphenol significantly inhibited the proliferation of MSI colorectal cancer cells and stably maintained the microsatellite state in MSI colorectal cancer. Tea polyphenol inhibited the gene expressions of HES1, JAG1, MT2A and MAFA, up-regulated the gene expression of BAX and down-regulated that of P38. Further research is required to investigate how these pathways are interrelated.

The study of effect of tea polyphenols on microsatellite instability colorectal cancer and its molecular mechanism.

INTRODUCTION: Tea polyphenol has been shown to have anti-colorectal cancer and anti-gene mutation effects, although the mechanism of inhibition of microsatellite instability (MSI) colorectal cancer is not known. MATERIALS AND METHODS: Using LoVo, HCT-116, HT-29, and SW480 cells treated with an aqueous solution of tea polyphenol, cell proliferation was detected by the methyl thiazolyl tetrazolium method, changes in microsatellite sequences by the Genescan method and changes in the gene expression of LoVo cells using Illumina expression arrays. RESULTS: The proliferation inhibition rate of LoVo, HCT-116, HT-29, and SW480 cells treated with tea polyphenol increased with increasing drug concentration and showed an increasing tendency with time. The proliferation inhibition rate of LoVo and HCT-116 cells with tea polyphenols was higher than that of HT-29 and SW480 cells, and there was a significant difference in the proliferation inhibition rate at 24, 72 h and 1 week. The microsatellite sequence of LoVo cells treated with tea polyphenols remained stable. DISCUSSION: The gene expression arrays and quantitative RT-PCR suggested that tea polyphenol inhibited the gene expression of metallothionein 2A (MT2A), transcription factor (MAFA), hairy and enhancer of split 1 (HES1), and jagged1 (JAG1) nearly twofold over controls. It was also found that tea polyphenol inhibited the BAX and p38 genes with a more than twofold difference but did not significantly inhibited the NFκB pathway. CONCLUSION: Tea polyphenol significantly inhibited the proliferation of MSI colorectal cancer signals maintained stable at the microsatellite state in MSI colorectal cancer. Tea polyphenol inhibited the gene expression of HES1, JAG1, MT2A, and MAFA but upregulated the gene expression of BAX and downregulated that of (P)38. Further research is required to investigate how these pathways are interrelated.

[Clinical study on acupuncture for treatment of chronic functional constipation].

OBJECTIVE: To discuss the effect of acupuncture for treatment of chronic functional constipation (CFC). METHODS: Ninety cases were treated with acupuncture. The following two groups of acupoints were used alternatively once every other day. The acupoints in the first group were Tianshu (ST 25), Qihai (CV 6), Shangjuxu (ST 37) etc., and Zhongliao (BL 33), Xialiao (BL 34), Dachangshu (BL 25) etc. in the second group, electroacupuncture was used at Zhongliao (BL 33), Xialiao (BL 34), Tianshu (ST 25) and Shangjuxu (ST 37), once a day, 10 times constituting one course. The defecation frequency, difficulty degree of defecation, defecation time, endless sensation of defecation, stool quality and awareness of defecation were observed and the Patient Assessment of Constipation Quality of Life (PAC-QOL) was evaluated by constipation patients' diaries. RESULTS: The scores of defecation frequency, difficulty degree of defecation, defecation time, endless sensation of defecation, stool quality, awareness of defecation and PAC-QOL were obviously improved after treatment (all P < 0.01). The total effective rate was 67.7% (61/90). The effect of acupuncture for chronic functional constipation in different dynamic mechanism was different. The effect of slow transit constipation (STC) was better than that of spastic pelvic floor syndrome (SPFS) (P < 0.05), and the effect of constipation caused by irritable bowel syndrome (IBS-C) was better than that of SPFS and relaxant pelvic floor syndrome (RPFS) (both P < 0.05). Fifty-two cases were effectively followed up. Three cases were cured, 6 cases were remarkably effective, 23 cases were effective and 20 cases were ineffective after 1 month of treatment. Three cases were cured, 5 cases were remarkably effective, 16 cases were effective and 28 cases were ineffective after 3 months. CONCLUSION: The effect of acupuncture for CFC with exact etiology, disease location and classification diagnosis is definite, but different dynamic mechanism has different effect. The treatment programs for SPFS and RPFS need to be optimized to improve the therapeutic effect.

[Study on thirty patients with slow-transmission constipation treated by acupuncture and moxibustion].

OBJECTIVE: To assess the therapeutic effects and acting specialty of acupuncture and moxibustion for treatment of slow-transmission constipation (STC). METHODS: A clinical pathway was created and Patient-Reported Outcomes (PROs) method was taken for efficacy evaluation dominantly. Acupuncture and moxibustion were applied to 30 STC patients on two groups of acupoints in alternation, with acupoints of Tianshu (ST25), Daheng (SP15), Fujie (SP14), Qihai (RN6), Guanyuan (RN4), Zusanli (ST36), and Shangjuxu (ST37) as group 1; Dachangshu (BL25), Shenshu (BL23), Baliao (BL31, BL32, BL33, BL34), and Sishencong (Ex-HN1) as group 2. Deep needling was applied on acupoints of abdominal and back region and moxibustion was put on Sishencong, 20 times as one course. The therapeutic effect was assessed based on the Patient Assessment of Constipation Quality of Life Questionnaire (PAC-QOL) method by comparing the Bristol scoring on quality of stool, awareness and frequency of defecation, degree of abdominal fullness sensation, and patients' quality of life (QOL) at different time points, i.e., pre-treatment, after 1, 2 and 3 weeks of treatment. RESULTS: Compared with the condition of pre-treatment, after 1, 2 and 3 weeks of treatment, cases using irritant laxative or glycerin enema reduced, with quality of stool normalized, scores for awareness and frequency of defecation increased, and abdominal fullness sensation lessened (all P < 0.01); both the total score and scores on the 4 domains of QOL (malaise, psychosocial complaint, anxiety and interest related to constipation, and satisfaction) were obviously reduced. No adverse event occurred during the treatment course. Therapeutic effectiveness assessment at the end of treatment showed that 13 patients were cured, 9 improved and 8 treated in vain; the corresponding cases assessed at 1 month after treatment were 10, 7, 13; and those at 3 months after were 7, 8, 15, respectively. CONCLUSION: Establishing a clinical pathway is helpful to patients in their continuous diagnosis and treatment. Using PROs method to evaluate the therapeutic effect could clearly reveal the superiority of acupuncture and moxibustion in improving symptoms and QOL in patients of STC.

[Anticancer effects of tea polyphenols on colorectal cancer with microsatellite instability in nude mice].

OBJECTIVE: To study the anticancer effects of tea polyphenols on colorectal cancer with microsatellite instability (MSI) in nude mice and to explore its mechanism. METHODS: A colostomy was performed on the caecum of nude mice. Tumor fragments collected from the subcutaneous tumor of hMSH2-absence colon carcinoma Lovo cell line were surgically implanted onto the submucosa of the caecum during colostomy to establish the model. Then, the nude mice were divided into untreated group and 50, 75 and 100 mg/kg tea polyphenols groups. The mice in tea polyphenols-treated groups were given intra-abdominal injection of 50, 75 and 100 mg/kg tea polyphenols respectively. The inhibition rates of tumors were calculated, and microsatellite instability (MSI) and the alteration of transforming growth factor-beta1 (TGF-beta1), TGF-beta2 and insulin-like growth factor (IGF) were detected by Genescan method at different times after the injection. RESULTS: The tumor volumes of the three groups began to decrease at the 1st week and decreased most greatly from 2 to 3 weeks after treatment, and then the tumors tended to increase. The study found that tea polyphenols could inhibit the tumor growth. The tumor inhibition rates in the three treated groups were significantly higher than those in untreated group 1, 2, 3 and 4 weeks after treatment (P<0.01). Detection of MSI showed that the colorectal tumor in the untreated group presented with four MSI signs, including BAT-25, D2S123, D5S346 and D17S250, and TGF-beta1, TGF-beta2, IGF expressions. After using the tea polyphenols, the microsatellite tended to become stable. CONCLUSION: Tea polyphenols can inhibit the mismatch-repair-gene deficient colorectal cancer in nude mice by down-regulating the microsatellite instability.

[Diagnosis and surgical management of adult Hirschsprung disease].

OBJECTIVE: To investigate the diagnosis and surgical treatment of adult Hirschsprung disease (AHD). METHODS: Clinical data of 10 patients with AHD undergoing operation from May 1985 to May 2005 were analyzed retrospectively. RESULTS: There were 7 males and 3 females with an age ranged from 14 to 40 years. All the cases had constipation, and were diagnosed by barium enema. Aganglionosis was located in distal sigmoid and rectum in 2 cases, in rectum in 7 cases, unknown in one case. Colostomy was performed in one, Ikeda s operation in 6, Rehbein operation in two,modified Swenson operation in one. After radical operation,7 patients had excellent continence function, one had good function, one had poor function. CONCLUSIONS: The diagnosis of adult HD mainly depends on the history of constipation, barium enema and manometry examination. The pull-through procedures are effective surgical treatments for adult HD. The operation type should be selected individually.
