This paper reviewed the present situation of acupoints and meridians issue from the angle of acupuncture and the infrasonic sound. Researches regarding the acupuncture process are studied from the angle of energy. The lifting-inserting method in acupuncture is considered as a way of inputting energy directly, and entwisting needle is considered as a way of inputting energy indirectly. As a result, the two ways caused meridian material (glue flexible body) oscillating. By the frequency of infrasonic wave, the energy is transmitted through the meridian lines, and the magnifying process is induced. Accordingly, the energy result of the body will be transmitted with acupuncture energy. At last, the dynamics equation and the energy equation analysis are given, from the angles of classic and modern physics, shows that the acupuncture function effect is the combined action effect produced by nervous system which stimulated by infrasonic sound energy.

OBJECTIVE:To investigate the relationship between therapeutic effects of N-acetylcysteine(NAC) on animals with fulminant hepatic failure and contents of plasma amino-acids METHODS:Plasma amino-acids were analysed as their precolumn derivatives with O-phthol-dialdehyde by reversed-phase high-performance liquid chromatographic separation and fluorescence detection RESULTS:NAC could decrease the contents of plasma amino-acids,increase the ratio of BCAA/AAA and decrease the mortality of fulminant hepatic failure animals CONCLUSION:Therapeutic effects of NAC on animals with fulminant hepatic failure were related to its effect on the contents of plasma amino-acids

E2Fs transcription factors can control transcription of genes involved in cellular proliferation,differentiation and apoptosis.So far,in mammals,E2F family has seven identified members,E2F-1,E2F-2,E2F-3,(E2F-4),E2F-5,E2F-6 and E2F-7,and each of has special function.Recently,many investigations have demonstrated that E2F-1 has an apparently unique capability to induce apoptosis,and its functions relate to P53、P73、APAF-1、Caspase3 、Caspase7、BcL-2 family members、DIP、SIVA 、NF-?B factor and so on.According to the dependence on P53,molecular mechanisms of E2F-1 induced apoptosis are classified as both P53-dependent and P53-independent.Therefore,(E2F-1) is a novel target site of tumor genetherapy.

Colorectal neoplasms always present with thickness of the intestinal wall or a soft tissue mass in the enteric cavity. Multi-slice computed tomography (MSCT) with high spatial resolution and advanced post-processing techniques can demonstrate the above signs of the tumor, and the invasive signs of adjacent structures and lymph node metastasis. Combined with three dimensional reformation images, MSCT shows a higher sensitivity than that of double contrast barium enema and electronic colonoscope. MSCT is promising in the diagnosis and preoperative evaluation of colorectal neoplasms.

Objective To investigate the role of the classification of Lauren in staging of gastric carcinoma and preoperative assessment using spiral CT. Methods Forty eight patients, 32 men and 16 women, who were 24～78 years old, with histologically and endoscopically proven gastric carcinoma, underwent spiral CT scans in prone position, with drug induced hypotonia and water filling. To induce gastric wall hypotonia and to maintain it during the entire examination, 10～15 mg of 654 2 was administered iv before basal scanning. All patinets underwent 2D, 3D and axial imaging using spiral CT, and 46 patients underwent dual phase contrast within one breathhold each. All patients with gastric carcinoma underwent staging and preoperative assessment by two radiologists according to the classification of Lauren. Results Spiral CT correctly detected all tumours. In our series, gastric carcinoma was of the diffuse type in 33 cases, of intestinal type in 15 cases; first stage in 2 cases, second stage in 18 cases, third stage in 15 cases and forth stage in 13 cases. There were 40 patients being performed operation, gastrectomy was performed in 33 patients and laparotomy was performed in 7 patients. The staging and preoperative assessment accuracy was 85.4% and 95.0% respectively, overstaging was 10.4%, and understaging was 4.2% according to the classification of Lauren. Correct rate of spiral CT detected lymph nodes (N1,N2) was 74.1% and 82.7% respectively. There are about 18 patienes whose arteries were invaded by tumors. With dual phase contrast, spiral CT can get well in detecting tumour, especially in staging gastric carcinoma in artery phase. Conclusions The classification of Lauren is recommended for staging of gastric carcinoma and preoperative assessment using spiral CT.

Objective To study the therapeutic effect of arbutin combined with glycyrrhizin on immune-inflammation. Methods The effect of arbutin combined with glycyrrhizin on adjuvant arthritis and on oxzolone induced mice ear swelling were investigated. PGE2 level in inflammatory tissue and LTB4 content from peritoneal macrophage of rat treated with arbutin and glycyrrhizin were determined. Results Arbutin combined with glycyrrhizin could inhibit Freund's complete adjuvant induced rat primary and secondary foot swelling. The combined group could also inhibit oxazolone induced mice ear swelling and decrease CD4+ T cell in blood. Compared with control group,PGE2 level in combined group was remarkable lower,and there was no difference between combined group and GL 400 mg/kg group. Arbutin combined with glycyrrhizin could inhibit LTB4 release from rat peritoneal macrophage. Conclusion Arbutin and glycyrrhizin has synergetic therapeutic effect on immune-inflammation.

Objective To investigate the short-term outcome of vacuum sealing drainage (VSD) in the treatment of infection early after tibiofibular fracture surgery.Methods A retrospective analysis was performed on 19 patients sustaining early infection after tibiofibular fracture surgery from December 2012 to December 2014.The patients consisted of 13 males and 6 females,aged from 26 to 57 years [(37.0 ± 5.3) years].There were 4 cases of isolate tibial fracture,2 isolate fibular fracture,and 13 tibial and fibular fracture.Open fractures were noted in 13 cases and close fractures in 6 cases.Infection occurred 14-21 days [(18.0 ± 3.3) days] after open reduction and internal fixation and was treated with gentamicin and VSD.Parameters were monitored dynamically after operation,including white blood cell count (WBC),C-reactive protein (CRP),erythrocyte sedimentation rate (ESR) and limb perimeter.Results The wound was basically debrided 7-10 days after VSD.Eighteen cases had one-stage wound closure with instrumentation preservance,and one case with progressed infection from soft tissue to bone marrow had instrumentation removal and wound suture.VSD decreased markers of inflammation including WBC,CRP,and ESR as well as limb perimeter.A follow-up of 6-24 month [(11.0 ± 2.3)months] showed fracture healing,without complications of detectable deformity growth,dysfunction,or chronic osteomyelitis.Conclusion VSD results in sufficient wound drain,reduction of swelling,decreased levels in CRP and ESR and controlled wound infection,which facilitates wound closure.

Objective To improve the applied value of Multi-slice CT (MSCT) in the diagnosis and treatment of the colonic tumours.Methods MSCT axial images reconstruction 4-D,MIP and CT virtual colonoscopy (CTVC) in 30 patients with colonic tumours proved histologically were analysed and compared these results with that of barium enema and colon endoscopy.Results The diagnostic correctly rate in this group was 100% by MSCT,while the diagnostic rate by CTVE and colon endoscopy was basicly identical.Conclusion MSCT is recommended for the diagnosis and treatment of the colonic tumour.

Objective To evaluate the contrast-enhanced 64-slice spiral CT(64-SCT) features and pathologic findings of coloniccancer comparatively.Methods 56 cases of colonic cancer underwent 64-SCT dynamic enhancement scans.All cases were classifiedaccording to 64-SCT features of arterial phase and then analysed pre-operatively with pathological comparation.Results There werecharacteristic manifestations on arterial phase of contrast-enhanced CT scan in all cases,the tumors with well differentiation appeared as slight-medial homongeneous enhancement in 23 cases,while undifferentiation tumors appeared as obviously inhomogeneous enhancement or layer-like enhancement in 33 cases.The tumors were classified according to their features on contrast-enhanced CT,the accuracy rate was 91.07%,the accuracy rate evaluated pre-operation was 92.86%.Conclusion 64-SCT dynamic scan has distinctive superiority in diagnosis and treatment of the colonic tumor.

Objective To study the metabolic characteristic of prostate cancer(PCa) in peripheral zone (PZ) with three-dimensional proton MR spectroscopic imaging (3D MRSI),and to evaluate the value of 3D MRSI in the differential diagnosis of prostate cancer in PZ. Methods 3D MRSI findings were reviewed in 18 benign prostatic hyperplasia (BPH) cases and 21 PCa cases.(Cho+Cre)/Cit and Cho/Cre ratios of PCa and PZ of BPH were retrospectively measured,(Cho+Cre)/Cit and Cho/Cre of PCa voxels were compared with BPH voxels. Results PZ of BPH showed dominant Cit,which was markedly higher than Cho and Cre. Significantly higher choline levels and lower citrate levels were observed in PCa compared with that of BPH. It showed statistically significant difference between (Cho+Cre)/Cit ratios of PCa voxels and BPH voxels,PCa voxels had minimal overlap with BPH voxels. It also showed statistically significant differences between Cho/Cre ratio of PCa voxels and BPH voxels,but there was some overlap between two groups. Conclusion 3D MRSI can be successfully applied to the diagnosis of cancer in the PZ on the basis of the elevation of Cho and the reduction Cit in cancerous tissue compared with that of PZ tissue of BPH.
