OBJECTIVETo probe the effect of previous analgesia of scalp acupuncture.

METHODSSixty cases of radical operation of intestinal cancer were randomly divided into 2 groups: a scalp acupuncture plus epidural analgesia (scalp acupuncture group) and an epidural analgesia group, 30 cases in each group. The scalp acupuncture group received scalp acupuncture from 20 min before operation to the end of the operation, and epidural analgesia at the end of the operation. The epidural analgesia group only received epidural analgesia at the end of the operation. Recovery of VAS scores, BCS scores and gastrointestinal function after operation were investigated to probe into effects of scalp acupuncture on epidural morphine analgesia after operation in the patient of intestinal cancer.

RESULTSThe VAS scores at 6 h, 12 h, 24 h and 48 h in the scalp acupuncture group were lower than the epidural analgesia group, with significant differences at 6 h and 12 h between the two groups (P < 0.05). BCS scores at the 4 time points in the scalp acupuncture group were lower than the epidural analgesia group with significant differences between the two groups (all P < 0.05). The scalp acupuncture group in recovery of bowel sound, exsufflation from the anus in the scalp acupuncture group was faster than the epidural analgesia group (P < 0.01).

CONCLUSIONScalp acupuncture has a certain previous analgesic effect, reducing discomfort of the patient after operation and promoting the recovery of gastrointestinal functions.

Objective:To investigate the effects of Chlamydia pneumoniae(Cpn) on SR-A1 and CD36 expression in THP-1-derived macrophages and role of c-Jun NH_2-terminal signal transduction pathway in the process.Methods:Cpn was propagated in Hep-2 cells.THP-1 monocytes were induced into macrophages by 160 nmol/L phorbol myristate acetate(PMA)for 48h,and were randomly allocated into four groups to be incubated continually: control group;Cpn infection group;Cpn and SP600125(a JNK inhibiter)group and SP600125 group.Lipid droplets in cytoplasm were observed by oil red O staining.The contents of intracellular cholesterol ester were detected by enzyme-fluorescence.The expression of SR-A1 and CD36mRNA and protein were determined by RT-PCR and Western blot, respectively. Results:THP-1-derived macrophages infected with Cpn resulted in large accumulation of lipid droplets and foam cell formation when co-cultured with LDL.Meanwhile,the expression of SR-A1 mRNA and protein were up-regulated by Cpn infection (P<0.05).However,the expressions of CD36 mRNA and protein in THP-1-derived macrophages infected with Cpn were unchanged.Moreover,the up-regulation of SR-A1 and foam cell formation induced by Cpn could be restrained by the JNK inhibiter SP600125 in a dose-dependent manner,and SP600125 had little impact on the expression of CD36 in THP-1-derived macrophages infected with Cpn.Conclusion:The up-regulation of SR-A1 but not CD36 expression is involved in mechanisms of Cpn inducing foam cell formation.And Chlamydia pneumoniae up-regulates the expression of SR-A1 via the JNK signal transduction pathway.This may be a novel mechanism for the foam cell formation induced by Cpn.

Objective To investigate the mechanisms of Chlamydia pneumoniae (C. pn)-induced foam cell formation, the expression of ATP binding cassette transporter AI ( ABCA1 ) and perexisome prolif-erator-activated receptor γ (PPARγ) were examined. Methods THP-1 monneytes were induced into mac-rophages after the addition of 160 nmol/L phorbol myristate acetate (PMA) for 72 h. THP-1-dorived macro-phages when co-cuhured 50 mg/L low density lipoprotein (LDL) were designated randomly in four groups: control (uninfected) group, C. pn infection group, rosiglitazone + C. pn infection group and rosiglitazone group. Lipid droplets in cytoplasm were observed by oil red O staining. The contents of intracellnlur choles-terol ester were detected by enzyme-flnoreseence. The expression of ABCA1, PPARγ, mRNA and protein were determined by RT-PCR and Western blot, respectively. Results C. pn down-regulated the expression of ABCA1, PPARγ at mRNA and protein levels in a concentration-dependent manner in THP-1-derived mac-rophages when co-incubated with LDL. Resiglitazone not only concentration-dependently alleviated the down-regulation of ABCA1 expression by C. pn infection (P<0.05), but also markedly suppressed the accumula- tion of lipid droplets and cholesteryl ester by C. pn at higher concentrations ( 10 and 20 μaol/L). Condu-sion C. pn induces foam cell formation by down-regulating the expression of ABCA1 via PPART pathway, which may provide a new evidence for the development and progression of atherosclerosis initiated by C. pn infection.

Objective To investigate the role of c-Jun N-terminal kinase (JNK) signal transduction pathway on the up-regulation of the expression of acyl-coenzyme A: cholesterol acyltransferasel (ACAT1) induced by Chlamydia pneumoniae (C. pn), and to discuss the mechanism of macrophages-derived foam cell formation induced by C. pn. Methods C. pn was propagated in Hep-2 cells. THP-1 monocytes were induced into macrophages by 160 nmol/L phorbol myristate acetate(PMA) for 48 h, and were randomly allocated into four groups to be incubated continually: control group, C. pn infection group, C. pn and SP600125 (a special JNK inhibitor)group and SP600125 group. Lipid droplets in cytoplasm were observed by oil red O staining. The contents of intracellular cholesterol ester were detected by enzyme fluorescence analysis. The expressions of ACAT1 mRNA and protein were determined by reverse transcriptase polymerase chain reaction(RT-PCR) and Western blot, respectively. Results Compared with the control group, the expressions of ACAT1 mRNA and protein were up-regulated in C. pn infection group [(4.16±0.26) vs. (2.17±0.18), (1.20±0.10)vs. (0.61±0.03), both P<0.05], and C. pn-induced foam cell formation was observed. The expressions of ACAT1 mRNA and protein and the foam cell formation were inhibited by SP600125 in a concentration-dependent manner (r = - 0.92, P<0.05; r= - 0. 96, P<0.05, respectively). Conclusions The up-regulation of ACAT1 expression is induced by C. pn via JNK signal transduction pathway, which is involved in the mechanism of C. pn-induced macrophage-derived foam cell formation.

AIM: To investigate the signal transduction mechanism of Chlamydia pneumoniae (Cpn) in down-regulating the expression of ATP binding cassette A1 (ABCA1) and ATP binding cassette G1 (ABCG1),the key molecules in cholesterol efflux and atherogenesis,from THP-1-derived macrophages. METHODS: Cpn was propagated in Hep-2 cells. THP-1 monocytes were induced into macrophages by 160 nmol/L phorbol myristate acetate (PMA) for 48 h,and were randomly allocated into 4 groups to incubate continually: control group,50 mg/L low density lipoprotein (LDL); Cpn infection group,Cpn (1×10~6 IFU) and 50 mg/L LDL; Cpn and SP600125 (a special JNK inhibiter) group,THP-1 macrophages were previously treated with different concentrations (1-20 μmol/L) of SP600125 for 1 h,and then infected with Cpn (1×10~6 IFU) and 50 mg/L LDL; SP600125 group,SP600125(20 μmol/L)and 50 mg/L LDL. The expressions of ABCA1/ABCG1 and peroxisome proliferator-activated receptor γ (PPARγ) from each group were detected then. The cholesterol efflux was detected by enzyme-fluorescence. The expressions of ABCA1/ABCG1 and PPARγ mRNA and protein were determined by RT-PCR and Western blotting,respectively. RESULTS: Cpn not only down-regulated the ABCA1/ABCG1 expression,but also down-regulated the expression of PPARγ,which regulated the ABCA1/ABCG1 genes transcriptions. However,the mentioned effects of Cpn infection were restrained by the special JNK inhibitor SP600125 in a dose-dependent manner. CONCLUSION: Chlamydia pneumoniae may down-regulate ABCA1/ABCG1 expression from THP-1-derived macrophages via JNK-PPARγ signal transduction pathway.

OBJECTIVETo observe the differences of therapeutic effect in primary trigeminal neuralgia (PTN) of hyperactive of liver yang type treated by deep and shallow puncturing at Xiaguan (ST 7).

METHODSSixty-three cases of PTN of hyperactive of liver yang type were randomly divided into a deep puncturing group (32 cases) and a shallow puncturing group (31 cases). Xiaguan (ST 7) of affected region, Hegu (LI 4) and Taichong (LV 3) of bilateral sides, Cuanzhu (BL 2), Sibai (ST 2) and Jiachengjiang (Extra) relevant to the affected branch of nerve stem were selected in both groups. In deep puncturing group, Xiaguan (ST 7) was punctured to the depth of spheno-palatine ganglion (SPG); Cuanzhu (BL 2), Sibai (ST 2) and Jiachengjiang (Extra) were respectively punctured to the depth of supraorbital foramen, infraorbital foramen and mental foramen. In shallow group, routine puncturing was applied; the needles were connected with G6805 electric acupuncture apparatus, and switched on for 30 min every time; the treatment was applied every other day. Pain index, traditional Chinese medicine symptoms index and clinical therapeutic effect were observed after 2 courses of treatment.

RESULTSIn deep puncturing group, the VAS scores and the traditional Chinese medicine symptoms scores (pain degree, pain frequency, upsetting, conjunctival congestion, bitter mouth and hypochondriac pain) after treatment were much more lower than those before treatment (all P < 0.01); in shallow puncturing group, except hypochondriac pain (P > 0.05), other indices above after treatment were obviously lower than those before treatment (P < 0.01, P < 0.05). Compared with the indices in both groups after treatment, the VAS scores, the pain degree, conjunctival congestion and total scores of traditional Chinese medicine symptoms in deep puncturing group were more significant (all P < 0.05). The total effective rate was 93.8% (30/32) in deep puncturing group, superior to that of 87.1% (27/31) in shallow puncturing group (P < 0.05). No any adverse reaction was observed in both groups.

CONCLUSIONThe therapeutic effect of trigeminal neuralgia of hyperactive of liver yang type treated with electroacupuncture is remarkable, and deep puncturing at Xiaguan(ST 7) to SPG is more effective than routine puncturing.

OBJECTIVETo study on regulative action of scalp acupuncture on oxidative stress reaction at operation stage.

METHODSFifty two cases selected for radical operation of intestinal cancer were randomly divided into a scalp acupuncture plus general anesthesia (scalp acupuncture group) and a simple general anesthesia group (general anesthesia group), 26 cases in each group. The scalp acupuncture group were treated first with scalp acupuncture for 20 min, followed by general anesthesia, with scalp acupuncture lasted till the end of operation. The general anesthesia group were treated only with simple intratracheal anesthesia. Effects of scalp acupuncture on malondialdehyde (MDA) level and superoxide dismutase (SOD) activity at the operation stage were observed.

RESULTSAfter operation, MDA levels decreased significantly (P < 0.05) in the two groups, but with no difference between the two groups in the different values of MDA before and after treatment (P > 0.05); there was no significant change in SOD before and after treatment in the scalp acupuncture group, and significantly decreased in the general anesthesia group (P < 0.05). There was a significant difference between the two groups in the different value of SOD before and after the operation (P < 0.05).

CONCLUSIONScalp acupuncture can inhibit the decrease of SOD activity, reducing oxidative stress reaction at operation stage.

OBJECTIVETo investigate the clinicopathological manifestations of early renal amyloidosis (AL) and its diagnostic criteria.

METHODSFifteen cases with early renal amyloidosis admitted from 1994 to 2001 were collected from the hospital, and their clinical and pathological features were reviewed. Of them, the initial diagnoses were not made by depending findings from the light microscopy (LM) and immunofluorescense (IF), but confirmed by electron microscopy (EM) afterwards. Immuno-electron microscopy (IEM) were applied for amyloidosis typing.

RESULTSMost patients of early renal AL were in the middle to old age. Nephrotic syndrome was the most prominent symptoms and signs accompanying with rare microscopic hematuria and hypertension. Most of them had a normal renal function. Pathological examinations of renal biopsies using LM and IF showed mild mesangial proliferation and mild thickening of glomerular basement membrane (GBM). Immunoglobulins and complements were negative or only scanty in certain cases, but in all cases there was a light chain protein deposition homogeously. There were 4 cases of minimal change glomerulopathy, 5 cases of mild mesangial proliferative glomerulonephritis, 5 cases of stage I membranous nephropathy, and 1 case of cast nephropathy diagnosed with LM. The amyloid fibrils (diameter 8 - 10 nm) were randomly distributed in the mesangium, along GBM and at the arteriolar wall under EM. Additionally, Congo red staining was positive. IEM demonstrated that amyloid fibrils labeled with colloid gold was combined with a kind of light chain protein which was confirmed as the light chain type of AL.

CONCLUSIONSThe diagnosis of early renal AL was occasionally neglected by depending only findings of LM and LF. However, special amyloid fibrils can be detected using EM. EM observation is an indispensable technique for the diagnosis of early renal AL and the typing of AL may further be determined by using IEM.

To investigate the anti-tumor and side effect of CpG ODN 1826 and CpG ODN2006 as an adjuvants on leukemic tumor in mouse-models, an acute lymphocytic leukemic tumor in mouse model was established, then inoculated inactivated L1210 cells alone or with different vaccine adjuvants were injected subcutaneously into each DBA/2 model mouse at different times. The activities of mice, the tumor formation rate and the growth status of leukemic tumor were observed. The tumor was examined by pathologic section. The results showed that the vaccine of inactivated L1210 cells and CpG ODN 1826 could decrease the leukemic tumor formation rate, slow down the growth of leukemic tumor mass in mice and obviously cause necrosis of tumor cells, but it could not prolong the life spans of the tumor-burden mice; while CpG ODN2006 could not only decrease the tumor formation rate, slow down the growth of tumor mass in mice and result in obvious necrosis of tumor cells, but also could eliminate the existing tumor mass in mice, and prolong the life spans of the tumor-burden mice. It is concluded that using CpG ODN2006 as an adjuvant enhances the anti-tumor effect against the leukemic tumor, prolong the life span of tumor-burden mice without obvious side effect.
