OBJECTIVETo observe treatment efficacy of acupuncture at different distal acupoints for acute lumbar sprain after massage.

METHODSOne hundred and fifty patients with acute lumbar sprain were randomly divided into a Yaotongdian (Extra) group, a Houxi (SI 3) group, a Weizhong (BL 40) group, a Chengshan (BL 57) group and a Shuigou (GV 26) group, total 5 groups, 30 cases in each one. After the same massage treatment and based on groups divided, different distal acupoints above-mentioned were selected to be acupunctured. Visual analogue scale (VAS) scores, lumbar activity and treatment efficacy of patients in 5 groups were evaluated.

RESULTSWith acupuncture at distal acupoints after massage,VAS scores of patients in 5 groups were decreased compared with those after massage treatment (all P<0.05); lumbar activity was all obviously improved (all P<0.01); and cured and markedly effective rates were all increased in comparison with those after massage (all P<0.01). But among 5 groups the differences of VAS scores, lumbar activity and cured and markedly effective rates were not statistically significant(all P>0.05).

CONCLUSIONBased on massage treatment, acupuncture at distal acupoints could further improve the treatment efficacy for acute lumbar sprain, but there is no obvious effective difference among every distal acupoint. As long as choosing acupoints with lower pain threshold and stimulating enough, good efficacy could be acquired for acute lumbar sprain.

Objective To evaluate the clinical efficacy of intraarterial infusion chemotherapy in patients with advanced and/or recurrent breast cancer. Methods From February 2000 to March 2003, 18 patients with advanced and/or recurrent breast cancer were treated with interaarterial chemotherapy (IAC). The Seldinger's technique was used in all patients. IAC was administered for 2-3 courses every 3-4 weeks for each patient. Results The proceduce was successfully performed in all 18 patients including one with a complete response, 12 of a partial response, none in 3, and with progression in 2. The overall response rate was 72.2%. The frequent adverse effects were fever, leukopenia, nausea, and vomiting but no severe complication occurred. Conclusion Intraarterial infusion chemotherapy is a safe, simple, complication-free and effective in the patients with advanced and/or recurrent breast cancer.

Objective To investigate the successful rate and the therapeutic effect of loosening posterior tubercle of cervical transverse process with CT-guided insertion or blind insertion of small needle knife for cervical spondylotic radiculopathy. Methods Ninety patients with cervical spondylotic radiculopathy were divided into CT-guided insertion group and blind insertion group in the admission order using the random number table method, 45 cases in each group. CT-guided insertion group adopted the insertion of small needle knife following by the guide of CT, and the blind insertion group adopted the insertion of small needle knife following by cervical bony landmarks and muscles. After insertion, the position of the small needle knife in patients of the two groups was located by CT scan. If the needle knife did not arrive to the foci, it will be inserted again following by the guide of CT till successful insertion and location. The successful rate for the two times of insertion was calculated, and the pain scores were evaluated by visual analogue scale(VAS). Results(1) The successful rate for the first insertion of CT-guided insertion group was 73.3％, and that of the blind insertion group was 47.8％, the difference being significant(P < 0.01). The successful rate for the second insertion of CT-guided insertion group was 92.2％, and that of the blind insertion group was 80.0％, the difference being significant (P<0.01). (2) After treatment for one week, pain VAS scores of the two group were decreased (P < 0.01 compared with those before treatment) , and the decrease in the CT-guided insertion group was more obvious than the blind insertion group (P < 0.05). Conclusion CT-guided insertion makes the small needle knife therapy be more accurate and safer, ensures much better therapeutic effect, and brings less pain in the patients.

Objective To evaluated the clinical outcomes of intravesical instillation resiniferatoxin(RTX) for the treatment of patients with idiopathic overactive bladder(IOAB).Methods 26 cases with IOAB were randomly divided into test(A,14 cases) and control(B,12 cases) groups.The patients in group A were treated by intravesical instillation with 40ml of 0.5% idocain retained within the bladder for 3 minutes at first and with 100ml of 100nmol/L RTX retained within the bladder for 30 minutes late.The patients in group B were treated by the same method,however,the furacilin solution(placebo) at a dilution 1∶5000 was used instead of 100nmol/L RTX.The efficacy(daily voiding frequency,urgent uresis,FDV,MCBC,Qmax) of the 2 groups were evaluated before,1 month and 3 months after treatment.Results The pre-treatment comparion with prost-treatmen at 1 month and 3 months of A group was significant(P0.05).14 patients(54%) had slightly stimulating symptom in the urethra or bladder,and were otherwise generally well tolerated.Conclusion Single administration of RTX is safe and effective in patients with IOAB.

Objective: To optimize the ultrahigh pressure extraction ( UPE) process for forsythoside from Forsythia suspensa by Box-Behnken experimental design. Methods:On the basis of single factor screening, a three-factor and three-level Box-Behnken ex-perimental design was employed with liquid/material ratio( X1 ) , extraction pressure ( X2 ) and extraction time ( X3 ) as the independent variables. The response variable was the extraction yield of forsythoside. Results:The optimal UPE conditions for forsythoside were as follows:the ratio of solvent to material (ml·g-1) was 70, the extraction pressure was 151 MPa, and the extraction time was 114 s. With the optimal extraction process, the extraction yield of forsythoside was 13. 15 mg·g-1 . Conclusion:As a novel extraction tech-nology for Chinese herbal medicines, UPE procedure has higher extraction yield, lower extraction temperature, shorter extraction time and less power consumption, which provides a brand-new method for the extraction of forsythoside from Forsythia suspensa.

Purpose To investigate the expression and clinical significance of p63 in nodular lymphocyte predominant Hodgkin lym-phoma (NLPHL) and classical Hodgkin lymphoma (CHL). Methods 15 cases of NLPHL and 54 cases of CHL were stained for CD45, CD30, p63, PAX5, CD20, CD15, Oct-2, BOB1, MUM1, EMA, EBV-LMP1 and Ki-67 by immunohistochemical methods of EliVision. EBER were detected by in situ hybridization method in 12 cases of CHL. Results The expression of p63 in NLPHL (53. 3%, 8/15) was significantly higher than that in CHL (0, 0/54) (P<0. 05). Conclusions p63 protein is frequently expressed in NLPHL and helpful in the differential diagnosis between NLPHL and CHL.
