ABSTRACT
OBJECTIVE@#Based on magnetic resonance imaging technology, the dangerous depth of straight needling and the safety of deep needling at Dachangshu (BL 25) are discussed, and data support is provided for standardizing deep needling at Dachangshu (BL 25).@*METHODS@#The horizontal cross-sectional images of 148 healthy adult subjects under the spinous process of the 4th lumbar vertebra were collected by magnetic resonance instrument, the anatomical structure was analyzed, and the dangerous depth of straight needling at Dachangshu (BL 25) was measured.@*RESULTS@#The dangerous depth of straight needling at Dachangshu (BL 25) was (11.2±1.3) cm and (11.0±1.2) cm on the left and right sides of males, and (9.8±1.3) cm and (9.7±1.3) cm on the left and right sides of females. There was a positive correlation between the dangerous depth of straight needling at Dachangshu (BL 25) and body mass index (BMI). In the case of similar body size, the dangerous depth of straight needling at Dachangshu(BL 25) in males was greater than that in females (P<0.01).@*CONCLUSION@#At present, the deep needling at Dachangshu (BL 25) used in clinic is safe. In clinical application of the deep needling at Dachangshu (BL 25), the depth of needle insertion can be determined according to body size and gender.

<p><b>OBJECTIVE</b>To observe the clinical therapeutic effects on severe acute pancreatitis (SAP) treated with electroacupuncture (EA), sparse-dense wave and 2 Hz/15 Hz, at Dachangshu (BL 25) and Shangjuxu (ST 37) assisting ulinastetin and explore the effective therapeutic method for SAP.</p><p><b>METHODS</b>A total of 120 patients of SAP were randomized into an observation group and a control group, 60 cases in each one. In the control group, the routine western medicine was adopted with the intravenous drip with ulinastatin. In the observation group, on the basis of the treatment as the control group, EA was applied at Dachangshu (BL 25) and Shangjuxu (ST 37). The treatment was given once every day, 20 min each time. The treatment was 2 weeks in the two groups. The recovery time of defecation, the recovery time of bowel sound, the remission time of abdominal pain and the hospitalization time were recorded in the patients of the two groups. The changes in the tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6) and amylase, as well as the scores in the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) were compared in the patients of the two groups before treatment, and on the 3rd, 8th and 14th days of treatment. The therapeutic effects, the cases of surgical transfer or the cases of the transfer of intensive care unit (ICU) were compared between the two groups.</p><p><b>RESULTS</b>The recovery time of defecation, the recovery time of bowel sound and the remission time of abdominal pain, as well as the hospitalization time in the observation group were shorter than those in the control group (all<0.05). The levels of TNF-α, IL-6 and amylase, as well as the scores of APACHE Ⅱ on the 3rd, 8th and 14th days of treatment were all reduced as compared with those before treatment in the two groups (all<0.05). The results in the observation group were lower than those in the control group (all<0.05). The total effective rate was 95.0% (57/60) in the observation group, better than 81.7% (49/60) in the control group (<0.05). There were 1 case of surgical transfer and 0 case in ICU transfer in the observation group, 3 cases of surgical transfer and 2 cases in ICU transfer in the control group, indicating the significant differences between the two groups (both<0.05). .</p><p><b>CONCLUSION</b>EA at Dachangshu (BL 25) and Shangjuxu (ST 37) displays the satisfactory accessory therapeutic effects on SAP treated with ulinastatin.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To compare the effects of electroacupuncture (EA) at "Dachangshu" (BL 25) or "Tianshu" (ST 25) for visceral sensitivity, gene expression product c-kit of colonic Cajal interstitial cells (ICC) and capsaicin receptor 1 (TRPV1) of irritable bowel syndrome (IBS) rats, so as to investigate the effect and mechanism differences of EA at the back point and the front point of large intestine for IBS rats.</p><p><b>METHODS</b>Forty-two Wistar neonatal rats were randomly divided into a blank group (9 rats) and a model group (33 rats). IBS model was established with mother and child separation, acetic acid enema in young rats and colorectal dilatation method. Twenty-seven IBS rats in life were randomly divided into a model control group, a Dachangshu group and a Tianshu group, 9 rats in each group. EA (disperse-dense wave, 2 Hz/100 Hz, 0.1-0.3 mA) for 20 min was used at "Dachangshu" (BL 25) and "Tianshu" (ST 25) respectively in the Dachangshu and Tianshu groups, once every other day, totally 5 times. The rats in the model control group were fixed with soft cloth sleeve for 20 min, without acupuncture. No intervention was used in the blank group. The stool property Bristol grading score was recorded before and after intervention in each group. The visceral sensitivity was evaluated by abdominal withdrawal reflex. The latency until the first systolic wave occurred and the number of systolic wave within 90 s were observed. Immunohistochemical was used to detect the positive expressions of c-kit and TRPV1, the ICC colon specific marker.</p><p><b>RESULTS</b>Compared with the blank group, the Bristol score increased，latency period shortened, systolic wave number increased, c-kit and TRPV1 positive expressions increased in the model control group (all <0.01). Compared with the model control group, the Bristol score decreased, latency period increased, systolic wave number decreased, c-kit and TRPV1 positive expressions decreased after intervention in the Dachangshu and Tianshu groups (<0.05, <0.01). Compared with the Dachangshu group, the TRPV1 positive expression decreased after intervention in the Tianshu group (<0.05).</p><p><b>CONCLUSION</b>EA at "Dachangshu" (BL 25) or "Tianshu"(ST 25) can improve the diarrhea in IBS model rats, reduce the visceral sensitivity, and its mechanism may be related to regulating the expressions of colon c-kit and TRPV1. EA at "Tianshu" (ST 25) is more apparent for TRPV1 than at "Dachangshu" (BL 25).</p>
