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 study the effect of hypoxial endothelia cell conditional medium(HECCM)on the proliferation of pulmonary arterial muscle cell(PASMC).Methods MTT assay was used to test the proliferation,immuno-cytochemistry was used to identify the expression of ?-SM-actin.Results(1)HECCM could promote the proliferation of PASMC,down-regulate their expression of ?-SM-actin.(2)DDPH could up-regulate the expression of ?-SM-actin in PASMC which was time-dependant.Conclusions DDPH could reverse the phenotype transformation of PASMC exposed to HECCM,the action was time-dependant.After some time DDPH could reversly transform PASMC to the normal contractile phenotype.

Objective To introduce the procedures and evaluate the clinic value of CT-guided interstitial 125I seeds implantation in treating lung cancer. Methods Thirty-one cases patients with lung cancer underwent CT-guided interstitial 125I seeds implantation. All patients were scanned on multi-spiral CT (Philips, MX 8000) with optical navigating system (pinpoint), and treatment plan system, needle, and 125I seeds (Chinese Academy of Science) were used. First of all, according to the size of tumor, TPS calculated the optimal quantity of seeds. Then, under the guidance of CT, 125I seeds were percutaneously implanted into the tumors for interstitial radiotherapy. CT follow-up examinations were performed 1, 2, and 6 months after the therapy, respectively. According to the size of tumor, curative effects were graded as 4 grades: grade Ⅰ: obvious relief (OR) (the size of tumor reduced up to 50%), grade Ⅱ: relief (PR) (the size of tumor reduced by 25%-50%), grade Ⅲ: slight relief (SD) (the size of tumor reduced by 1%-25%), and grade Ⅳ: no effect (PD) (the size of tumor did not reduce or increase, and clinic symptoms showed no relief). Results At 1 month, 9 cases were classified as grade Ⅰ, 6 as grade Ⅱ, 13 as grade Ⅲ, and 3 as grade Ⅳ, respectively. At 2 months, 17 cases were grade Ⅰ, 8 grade Ⅱ, 3 grade Ⅲ, and 3 grade Ⅳ, respectively. At 6 months, 23 cases were grade Ⅰ, 3 grade Ⅱ, 2 grade Ⅲ, and 3 grade Ⅳ, respectively. Conclusion CT-guided interstitial 125I seeds implanted was a safe, reliable, and effective curative method for lung cancer.
