OBJECTIVE: To observe the clinical efficacy of acupuncture combined with thunder-fire moxibustion in treating low back pain with cold-damp. METHODS: Seventy-two patients of low back pain with cold-damp were randomly divided into an observation group (36 cases, 1 case was eliminated) and a control group (36 cases, 1 case dropped out). The control group received acupuncture at Jizhong (GV6), Yaoyangguan (GV3), ashi points, bilateral Shenshu (BL23), Dachangshu (BL25), and Weizhong (BL40) for 30 min daily. The observation group was treated with thunder-fire moxibustion in addition to the same acupuncture regimen as the control group, once daily. Both groups were treated for 6 consecutive days followed by one rest day, for a total duration of 4 weeks. The visual analog scale (VAS) score, Oswestry disability index (ODI) score, Japanese Orthopedic Association (JOA) score, present pain intensity (PPI) score, and serum levels of β-endorphin (β-EP), 5-hydroxytryp tamin (5-HT), and substance P (SP) were compared before and after treatment, and the clinical efficacy was also compared between the two groups. RESULTS: Compared before treatment, the VAS scores, ODI scores, PPI scores, and serum levels of 5-HT and SP were decreased (P<0.01), while JOA scores and serum levels of β-EP were increased (P<0.01) in both groups after treatment. The observation group showed lower VAS, ODI, and PPI scores and serum levels of 5-HT and SP than those in the control group (P<0.05), as well as higher JOA score and serum level of β-EP (P<0.05). The total effective rate in the observation group was 94.3% (33/35), higher than 82.9% (29/35) in the control group (P<0.05). CONCLUSION Acupuncture combined with thunder-fire moxibustion could effectively alleviate pain and improve lumbar function in patients of low back pain with cold-damp, possibly by regulating β-EP, 5-HT, and SP levels.

OBJECTIVE: To observe the effect of perioperative transcutaneous electrical acupoint stimulation (TEAS) on postoperative fatigue syndrome (POFS) in elderly patients undergoing laparoscopic radical gastrectomy. METHODS: A total of 80 elderly patients scheduled for laparoscopic radical gastrectomy were randomized into a TEAS group and a sham TEAS group, 40 cases in each one. In the TEAS group, TEAS intervention was applied at bilateral Hegu (LI4), Neiguan (PC6), Zusanli (ST36) and Sanyinjiao (SP6) from 30 min before anesthesia induction until surgery completion, and at 18:00 on 1st, 2nd and 3rd days after surgery, once a day, 30 min a time. In the sham TEAS group, the same acupoints were selected and connected to the electroacupuncture device at the same time, without electrical stimulation. One day before surgery and 1, 3, 7 days after surgery, the 10-item short form of identity consequence fatigue scale (ICFS-10) score was observed, and the POFS incidence rate of 1, 3, 7 days after surgery was assessed in the two groups. One day before surgery, surgery completion, and 1, 3 days after surgery, the serum levels of superoxide dismutase (SOD), β-endorphin (β-EP) were detected; 1 day before surgery and 1, 3, 7 days after surgery, the serum level of tumor necrosis factor-α (TNF-α) was detected in the two groups. The pain visual analog scale (VAS) score was observed at 24, 48 and 72 h after surgery; the intraoperative dosage of propofol and remifentanil, and the incidence rate of postoperative nausea and vomiting, itching, respiratory depression were recorded in the two groups. RESULTS: In the TEAS group, on 1, 3, 7 days after surgery, except for the scores of item 8-10, the item scores and the total scores of ICFS-10 were lower than those in the sham TEAS group (P<0.001); on 3 and 7 days after surgery, the POFS incidence rates were lower than those in the sham TEAS group (P<0.05). In the TEAS group, on 1 and 3 days after surgery, the serum levels of SOD were higher than those in the sham TEAS group (P<0.05, P<0.01); at surgery completion, and on 1, 3 days after surgery, the serum levels of β-EP were higher than those in the sham TEAS group (P<0.001, P<0.01); on 1, 3, 7 days after surgery, the serum levels of TNF-α were lower than those in the sham TEAS group (P<0.01, P<0.001). In the TEAS group, at 24, 48 and 72 h after surgery, the pain VAS scores were lower than those in the sham TEAS group (P<0.001, P<0.01, P<0.05); the intraoperative dosage of remifentanil was lower than that in the sham TEAS group (P<0.001); the incidence rate of postoperative nausea and vomiting was lower than that in the sham TEAS group (P<0.01). CONCLUSION Perioperative TEAS intervention can effectively reduce the incidence rate of POFS, improve fatigue symptom and mental state in elderly patients undergoing laparoscopic radical gastrectomy, its mechanism may related to enhancing endogenous β-EP release, inhibiting inflammatory response, and reducing central oxidative stress, thereby promoting postoperative recovery.

OBJECTIVETo explore the protection of high intensity microwave radiation on hypothalamo-pituitary-adrenal axis (HPAA) activity and hippocampal CA1 structure in rats and the protectiveeffect of Qindan Granule (QG) on radiation injured rats.

METHODSTotally 48 Wistar rats were randomlydivided into 8 groups, i.e., the normal control group, post-radiation day 1, 7, and 10 groups, 7 and 10days prevention groups, day 7 and 10 treatment groups, 6 in each group. Rats in prevention groups wererespectively administered with QG liquid (1 mL/100 g, 4. 75 g crude drugs) for 7 days and 10 days bygastrogavage and then microwave radiation. Then preventive effect for radiation injury was statisticallycalculated with the normal control group and the post-radiation day 1 group. Rats in treatment groupswere firstly irradiated, and then administered with QG liquid (1 mL/100 g, 4.75 g crude drugs). Finally preventive effect for radiation injury was statistically calculated with the normal control group, post-radiation day 7 and 10 groups. Contents of corticotrophin releasing hormone (CRH), beta endorphin (beta-EP), adrenocorticotropic hormone (ACTH), and heat shock protein 70 (HSP70) were detected. Morphological changes and structure of hippocampal CA1 region were observed under light microscope.

RESULTSCompared with the normal control group, contents of CRH and beta-EP significantly decreased in each radiation group. Serum contents of ACTH and beta-EP significantly increased in post-radiation day 1 and 7 groups (P < 0.05). Compared with radiation groups, beta-EP content in serum and pituitary significantly increased, and serum ACTH content significantly decreased in prevention groups (P < 0.05). Pituitary contents of CRH and beta-EP significantly increased in prevention groups. Serum contents of ACTH, beta-EP, and HSP70 were significantly lower in day 7 treatment group than post-radiation day 7 group (P < 0.05). Morphological results showed that pyramidal neurons in the hippocampal CA1 region arranged in disorder, with swollen cells, shrunken and condensed nucleus, dark dyeing cytoplasm, unclear structure. Vessels in partial regions were dilated with static blood; tissues were swollen and sparse. In prevention and treatment groups pathological damage of hippocampal CA1 region was obviously attenuated; neurons were arranged more regularly; swollen, pycnotic, or deleted neuron number were decreased; vascular dilatation and congestion was lessened.

CONCLUSIONQG could affect HPAA function and activity of high intensity microwave radiated rats, showing certain preventive and therapeutic effects of microwave radiated rats by adjusting synthesis and release of partial bioactive peptides and hormones in HPAA, improving pathological injury in hippocampal CA1 region.

OBJECTIVETo investigate the clinical significance of dynamic changes in the serum inflammatory cell factors consisting of &beta;-endorphin (&beta;-EP) , endothelins (ET) , tumor necrosis factor (TNF) , and nitric oxide (NO) after acute paraquat poisoning (APP).

METHODSThe 26 patients with APP (as observation group) were treated and the serum levels of plasma &beta;-EP, ET, TNF, and NO were measured simultaneously. The 20 healthy volunteers from relatives of the patients (as control group) were also included in the study and their serum levels of &beta;-EP, ET, TNF, and NO were measured.

RESULTSIn the 26 patients with APP, 10 were cured and 16 died. The serum levels of &beta;-EP, ET, NO, and TNF in the 10 cured patients increased significantly immediately after admission, reached the peak values on day 2, and then decreased gradually and returned to the normal ranges after day 9. The serum levels of &beta;-EP, ET, NO, and TNF in the 16 dead patients increased significantly on admission and kept rising in the course of treatment. The dead patients had significantly increased serum levels of &beta;-EP, ET, NO, and TNF compared with the cured patients (all P<0.01).

CONCLUSIONCompared with those in cured patients with APP, the serum levels of &beta;-EP, ET, NO, and TNF in dead patients with APP are significantly higher, keep rising, and maintain at high levels, indicating a severe condition.

OBJECTIVETo investigate the relationship of the common Traditional Chinese Medicine (TCM) syndrome pattern of chronic pelvic pain syndrome (CPPS) with the contents of substance p and beta endorphin in the plasma, and provide reference data for the clinical diagnosis, differentiation and treatment of CPPS by TCM.

METHODSWe observed 98 cases of CPPS, which were classified into a lower-part damp-heat invasion group (group A, n = 32), a blood stasis-induced collateral obstruction group (group B, n = 34), and a damp-heat stagnation group (group C, n = 32) according to the TCM syndrome differentiation. Another 35 normal healthy young men were enrolled as controls. We measured the contents of substance p and beta endorphin in the plasma by immunoradiometry and ELISA, and analyzed their relationship with the TCM syndrome pattern.

RESULTSThe contents of plasma substance p were significantly higher in groups A ([1135.76 +/- 166.45] pg/ml), B ([1 337.84 +/- 170.81] pg/ml), and C ([1 210.01 +/- 162.27] pg/ml) than in the control ([574.99 +/- 113.09] pg/ml) (all P < 0.01), while the contents of plasma beta endorphin in groups A ([212.70 +/- 29.49] pg/ml), B ([157.99 +/- 24.01] pg/ml), and C ([180.81 +/- 20.20] pg/ml) were remarkably lower than that in the control ([274.73 +/- 27.64] pg/ml) (all P < 0.01).

CONCLUSIONIn the plasma of CPPS patients, the content of substance p is significantly elevated and that of beta endorphin markedly reduced, which suggests that they may be involved in the inflammatory reaction of CPPS. The levels of plasma substance p and beta endorphin can be used as valuable reference for the TCM classification of chronic prostatitis.

OBJECTIVETo observe the effectiveness and safety of electroacupuncture (EA) at Neimadian (Extra) and Neiguan (PC 6) for analgesia after thoracic surgery.

METHODSOne hundred and twenty cases of thoracic surgery were randomly divided into an electroacupuncture (EA) group (60 cases) and a medication group (60 cases). EA was applied at Neimadian (Extra) and Neiguan (PC 6) for postoperation analgesia in the EA group, while patient-controlled intravenous analgesia (PCIA) was applied in the medication group. The score of visual analogue scale (VAS), analgesia effect, safety and beta-endorphin level after the treatment in both groups were compared.

RESULTSCompared with those before the treatment, the VAS scores in every time point after surgery were decreased (all P < 0.05), which were lower in the EA group (P < 0.01). The excellent and good rates were 96.7% (58/60) and 75.0% (45/60) seperately, the analgesia effect in the EA group (2 h after operation) was superior to that in the medication group (P < 0.01). The safety degree in EA group was higher to that in the medication group (P < 0.01). Compared with that before the treatment, the beta-endorphin level in two groups after treatment was both increased, which was higher in the EA group (P < 0.01).

CONCLUSIONElectroacupuncture at Neimadian (Extra) and Neiguan (PC 6) has better analgesia effect (2 h after operation) and safety than PICA on analgesia after thoracic surgery.

OBJECTIVETo observe the analgesia effectiveness and safety of electroacupuncture at Neimadian(Extra) for postoperation of abdominal surgery.

METHODSOne hundred and twenty patients with routine abdominal surgery were randomly divided into an acupuncture group and a medication group, 60 cases in each group. The acupuncture group was treated with electroacupuncture at Neimadian(Extra), which was located on the inside of lower leg, 7 cun above the internal malleolus and 0.5 cun from post edge of tibial. The medication group was treated with patient-controlled intravenous analgesia (PCIA) with Sufentanil. After the treatment, the Visual Analogue Scale (VAS), the security, the analgesic effect and beta-endorphin content were compared.

RESULTSThe postoperative VAS score at 2, 4, 8, 16, 24 and 48 h in the acupuncture group was lower than those in the medication group (all P < 0.05). The analgesic effect at 2, 4, 16 and 24 h after surgery in the acupuncture group were superior to those in the medication group (P < 0.05, P < 0.01). The beta-endorphin content at 0, 8, 16 and 48 h after surgery in both groups were increased, and the acupuncture group was superior to the medication group (all P < 0.05). The security class after surgery in the acupuncture group was higher than that in the medication group (P < 0.05).

CONCLUSIONThe analgesic effect and safety of electroacupuncture at Neimadian(Extra) in postoperation of abdominal surgery are superior to those of the PCIA with Sufentanil.

OBJECTIVETo explore the clinical effect and mechanism of electroacupuncture at Jiaji (EX-B 2) on drug craving of heroin addicts.

METHODSOne hundred and twenty cases of heroin addicts were randomly divided into 4 groups, 30 cases in each. In acupuncture group 1, the Jiaji (EX-B 2) points of T5-T7 and Shenshu (BL 23) were selected with electroacupuncture; in acupuncture group 2, Neiguan (PC 6), Shenmen (HT 7) and Zusanli (ST 36) etc. were selected with electroacupuncture; in simulation group, Zusanli (ST 36) and Sanyinjiao (SP 6) were selected with analog electrical stimulation, and in blank group no any therapy was applied. The changes of drug craving were evaluated by Visual Analogue Scale (VAS) and the changes of beta-EP and Dyn-A in plasma before and after treatment were tested by radioimmunoassay.

RESULTSThe relapse rate of 77.3% (17/22) in acupuncture group 1 was lower than those of 88.5% (23/26) in acupuncture group 2, 90.5% (19/21) in simulation group and 95.7% (22/23) in blank group (all P < 0.05). At the 8th and 10th week of treatment, the VAS scores in acupuncture group 1 and 2 were much lower than those in blank group and simulation group (all P < 0.01); in which, it was lower in acupuncture group 1 than that in acupuncture group 2 (P < 0.05), and lower in simulation group than that in blank group. After 10 weeks of treatment, compared with the status before treatment, beta-EP and Dyn-A in plasma were increased in acupuncture group 1 and 2 (P < 0.05, P < 0.01), Dyn-A was decreased in both simulation and blank groups (both P < 0. 01) which was less obvious than those in both acupuncture groups (both P < 0.01) and superior in acupuncture group 1 than that in group 2 (P < 0.05).

CONCLUSIONElectroacupuncture at Jiaji (EX-B 2) can suppress the drug craving and reduce the relapse rate, and the mechanism may be related with the content of beta-EP, especially the increase of Dyn-A in plasma.

OBJECTIVETo probe into the optimal frequency of electroacupuncture for the access to the best anesthesia.

METHODSSixty cases of optional thyroid surgery were randomly divided into group A, group B and group C, 20 cases in each group. In group A, 2 Hz/100 Hz disperse-dense wave was selected in stimulation. In group B, 2 Hz/15 Hz disperse-dense wave was selected. Group C was the control group without electric stimulation applied. Hegu (LI 4) and Neiguan (PC 6) were stimulated bilaterally. Cervical plexus block was produced after 15 min acupuncture. The concentration changes in plasma cortisone (COR) and beta-endorphin (beta-EP) were compared among 4 time-points, named before anesthesia (T1), before skin incision after induction (T2), thyroid traction in surgery (T3) and the end of surgery (T4).

RESULTSGroup B achieved the highest significant rate of analgesia (50.0%, 10/20) and that in group C was the lowest (10.0%, 2/20). COR content was the highest at T2 in group A and that was the lowest at T3 in group B. At the end of surgery, COR content was up the maximum in 3 groups, but still COR content was the lowest in group B in comparison. The plasma beta-EP content decreased apparently at T3 and T4 in group B as compared with the value before (both P < 0.05).

CONCLUSIONIn electroacupuncture-assisted anesthesia, 2 Hz/15 Hz disperse-dense wave achieves the optimal anesthesia compared with 2 Hz/100 Hz disperse-dense wave, and moreover inhibits stress reaction induced by anesthesia surgery.

OBJECTIVETo evaluate the adjuvant effect of transcutaneous electrical acupoint stimulation (TEAS) in propofol-fentanyl anesthesia in partial mastectomy.

METHODSNinety patients undergoing partial mastectomy were randomly divided into 3 groups (n=30), namely group A with propofol-fentanyl anesthesia (PFVA), group B with PFVA and TEAS at Hegu-Laogong and Neiguan-WaiGuan acupoints, and group C with PFVA and TEAS at Hegu-Laogong, Neiguan-Waiguan, and bilateral Jianjing acupoints. The bispectral index (BIS), heart rate (HR), saturation of pulse oxygen (SpO2), blood pressure (BP), the reaction of patients to the incision and awakening quality were observed at different time points. Blood samples were obtained from the dorsal artery of the foot to determine the levels of adrenaline and beta-endorphin using the enzyme-linked immunosorbent assay before TEAS (entry into the OR in group A) and at 30 min after TEAS (30 min after entry into the OR in group A), 5 min after incision, end of the surgery and awakening.

RESULTSThirty minutes after TEAS (or 30 min after entry into the OR in group A), BIS, BP and HR were all decreased significantly in groups B and C (P<0.05) but remained stable in group A (P>0.05). The plasma propofol concentration of groups B and C were significantly lower than that in group A, and group B had the highest plasma propofol concentration (P<0.05). The total dose of propofol in groups B and C were decreased by 19% and 27% in comparison with that in group A, respectively. Compared with the basal value, the content of beta-endorphin in groups B and C increased obviously 30 min after TEAS, being the highest in group C (P<0.05); the adrenaline level in groups B and C remained stable after TEAS (P>0.05).

CONCLUSIONTEAS provides an adjuvant effect in propofol-fentanyl anesthesia and obviously enhances the analgesia effect.
