Based on the structure and function of acupoint and in association of the definition and principle of sensor, the acupoint is the sensitive element, being sensitive to the physical stimulation with acupuncture and moxibustion and sensitively responded to the disorders; the acupoint is the sensing element, transforming the changes of the acupoint information via the complicated internet conduction, integration and regulation, so as to generate the effects on organic body; the acupoint is the conversion element, transforming every irritation into the bioelectric signal or optical signal so that the organic body could recognize it. Therefore, the acupoint is regarded as the sensor of information in the organic body.

Xiatianwu tablet is based on the theory of traditional Chinese medicine (TCM), combined with modern TCM pharmacology and selected 33 famous traditional Chinese crude drugs to compose. Its recipe helps cure rheumatism, relax tendons, promote blood circulation to relieve pain, et al. Although Xiatianwu tablets are widely applied to clinical remedy such as rheumatic arthritis, lumbar disc hernia, osteoarthritis and so on, there is no report about its application in fracture. This article is to observe the efficacy of compound Xiatianwu tablets in elderly patients with osteoporotic distal radius fractures and its impact on the wrist function and complications. 180 elderly patients with osteoporotic distal radius fractures, from January 2011 to June 2014, were divided into observation group and control group by the method of random number table, each group had 90 cases. The control group were gave Caltrate D after manipulative reduction and plaster immobilization, observation group were treated with compound Xiatianwu tablets in the basis of the control group. Efficacy, wrist function and complication rates were observed in two groups after treatment. The excellent and good rate was 95.56% in observation group better than 77.78% in control group, the difference was statistically significant (χ2 = 4.712, P < 0.05). The complication rate in observation group was significantly lower compared with the control group (P < 0.05). This study shows that compound Xiatianwu tablets can improve the efficacy in elderly patients with osteoporotic distal radius fractures, reduce the incidence of complications and relieve the pain of patients which plays a significant role in improving the quality of life.

Designed the degenerate primers of alcohol dehydeogenase and L-lactate dehydrogenase to aug- ment Ethanoligenens harbinense B49 genomic DNA, and obtained about 780 bp and 610 bp PCR product respectively. Augmented flank sequences of the two PCR fragments with the Cassette PCR method. Similar- ity alignment showed that the products of the cloned DNA were very high similar to those of alcohol dehy- drogenase genes and L-lactate dehydrogenase genes respectively. One of the two sequences was 1902 bp long, and the ORF of adh was 1101 bp long and encoded 366 amino acids. Its putative molecular weight was about 39.71 kD, its calculational isoionic point was pH 5.93. The maximal identity and positive was 51% and 73% with Clostridium thermocellum ATCC 27405 adh. The other one was 2490 bp long, and the ORF of adh was 951 bp long and encoded 316 amino acids. Its putative molecular weight was 34.23 kD, its calcula-tional isoionic point was pH 6.09. The maximal identity and positive was 55% and 74% with Bacillus megaterium L-ldh. Successfully cloning these two genes would not only enrich the gene resources of L-lactate dehydrogenase and alcohol dehydrogenase genes, but also give the scientific warrant for the meta- bolic engineering research and the construction of the gene-engineering bacteria.

Objective To study the clinical features,diagnosis and treatment of eosinophilic granuloma of bone(EGB).Methods Twelve cases(8 male and 4 female)of EGB and their medical record,imaging examinations,follow-up data were reviewed,and the lesion sites,symptom and clinical features were analyzed with reference to relative literature.Results Nine unifocal cases were found in the cervical spine(3 cases),the thoracic spine(1 case),the lumber spine(1 case),the femur(1 case),the metacarpal bones(1 case),and the ilium(2 cases).Three multifocal cases were found in the thoracic and lumber spine(1 case),in the femur,the multiple ribs,the skull,the scapula(1 case)and in the skull,the femur,the ilium(1 case).The most common presenting symptom was pain at the lesion site and restricted motion was obviously in the cervical lesion.The case of the thoracic lesions was found neurologic deficit.Osteolytic destruction was found in the radiologic examination in EGB and the periosteal reaction was found in the long bone lesions,and vertebra plana was considered as typical cha-racteristics in the spine lesion.The lesions not in the spine were diagnosed by biopsy,exclusive methods and close following-up were performed in the spine lesions.Two unifocal were healed spontaneously and three were performed with curettage with one bone grafting.Multifocal and the lesions in the spine underwent chemotherapy.All cases were followed up and no recurrence was found.Conclusions EGB is commonly solitary and not seldom in the spine.Topical pain may be chief complaint.Osteolytic image was found in the radiologic examination.Biopsy and exclusive methods combining closely follow-up were used for diagnosis.EGB is self-limited observation,so curettage or chemotherapy can be used in treatment,and prognosis is good.

OBJECTIVETo investigate the selective killing of colorectal tumor cells by lentivirus-mediated double suicide gene under the regulation of KDR promoter.

METHODS293T packaging cells were transfected with the plasmid FGW-KDRP-CD/TK to obtain the infectious viruses. KDR-expressing LoVo cells and LS174T cells that did not produce KDR were transfected with the recombinant virus, and the transfection efficiency was evaluated by the fluorecence microscope. RT-PCR was employed to examine the expression of CDglyTK. After treatment of the cells with 5-FC and GCV, the killing effects on the two cell lines were evaluated.

RESULTSThe recombinant construct showed similar infection rate of the two cell lines. RT-PCR demonstrated that CDglyTK gene was expressed only in LoVo cells infected with FGW-KDRP-CD/TK but not in LS147T cells, and the sensitivity of the two cell lines to the prodrugs was significantly different (P<0.001). The killing effect of the double suicide gene was much stronger than that of single suicide gene administered (P<0.001).

CONCLUSIONThe double suicide gene driven by KDR promoter has specific killing effect on the KDR-expressing colorectal tumor cells.

Objective:To explore the urgent management strategy for quadriplegia following China Wenchuan earthquake under filed condition.Methods:The 57-year-old male patient was sent to the earthquake relief team of Changzheng Hospital,Second Military Medical University.He was hit by heavy object during the Sichuan earthquake 6 days ago.Physical examination revealed cervical spinal cord injury accompanied by incomplete paralysis.The patient underwent cervical 3-7 laminectomy under general anesthesia.Results: After surgery,the muscle strength of lower limbs recovered to grade four from grade one;the muscle strength of upper limbs recovered to grade five from grade three.Sensory loss was found below the nipple level and totally recovered after operation.Conclusion:Early surgery for quadriplegia following earthquake trauma can timely relieve compression to the spinal cord and therefore improve prognosis of patients.Under field condition where facilities are not readily available,decompression of spinal cord can be achieved by lamineetomy via posterior approach.The key to successful operation is correct diagnosis and skillful manipulation.

Objective: To observe the effects of moxibustion at Shenshu (BL 23), Zusanli (ST 36) and Shenque (CV 8) on the energy metabolism and endocrine metabolism indicators of rats undergoing one-time exhaustive swimming, and to explore the differences between moxibustion at different points in the effects on anti-exercise fatigue. Methods: Forty-eight male SPF rats were randomly divided into a blank group, a model group, a non-meridian and non-acupoint group, a Shenshu (BL 23) group, a Zusanli (ST 36) group, and a Shenque (CV 8) group using random number table method, with eight rats in each group. Except for the blank group, rats in the other groups were subjected to replicating the one-time exhaustive model using the weight-bearing swimming experiment. Except for the model group, the other model rats received mild moxibustion immediately after swimming. Rats in the non-meridian and non-acupoint group received mild moxibustion at bilateral subcostal non-meridian and non-acupoint points, those in the Shenshu (BL 23) group received mild moxibustion at bilateral Shenshu (BL 23), those in the Zusanli (ST 36) group received mild moxibustion at bilateral Zusanli (ST 36), and those in the Shenque (CV 8) group received mild moxibustion at Shenque (CV 8) for 15 min. Four hours after the exhaustive swimming, femoral artery blood was collected to detect blood lactate (BLA), lactate dehydrogenase (LDH), creatine kinase (CK), creatinine (CRE), blood urea nitrogen (BUN), cortisol (C) and testosterone (T) levels, and calculate the T/C ratio. Results: Compared with the blank group, rat's serum levels of BLA, LDH, CK, BUN and C in the model group and the non-meridian and non-acupoint group were increased, and serum levels of CRE and T, and T/C ratios were decreased (P<0.01 or P<0.05); compared with the model group and the non-meridian and non-acupoint group, the serum levels of BLA, LDH, CK, BUN and C in the Shenshu (BL 23) group, Zusanli (ST 36) group and Shenque (CV 8) group were decreased, and the serum CRE and T levels, and the T/C ratios were increased (all P<0.01); compared with the Shenshu (BL 23) group, the serum CK level was decreased in the Shenque (CV 8) group (P<0.01), the serum levels of T and C were decreased in the Zusanli (ST 36) group and Shenque (CV 8) group (P<0.01 or P<0.05), and the T/C ratio was increased in the Shenque (CV 8) group (P<0.01); compared with the Zusanli (ST 36) group, the serum CK and BUN levels were decreased (P<0.01, P<0.05), and the T/C ratio was increased in the Shenque (CV 8) group (P<0.05). Conclusion: Moxibustion at Shenshu (BL 23), Zusanli (ST 36) and Shenque (CV 8) shows different anti-fatigue effects by regulating the energy metabolism and endocrine metabolism in rats undergoing one-time exhaustive swimming. Moxibustion at Shenshu (BL 23) is better in promoting energy synthesis. Moxibustion at Shenque (CV 8) is more effective in regulating synthesis and decomposition of the skeletal muscle proteins.

OBJECTIVETo study the effects of electromagnetic pulse (EMP) exposure on the morphological change and excretion functions of mouse microglia (BV-2) cells and possible mechanism.

METHODSBV-2 cells were divided into two groups: the group exposed to EMP at 200 kV/m for 200 pulses and sham exposure group. At 1, 6, 12 and 24 hour after exposure the cells and culture supernatant were collected. Cellular morphological change was observed under invert microscope, the levels of TNF-α, IL-1β and IL-10 in culture supernatant were determined by enzyme-linked immunosorbent assay (ELISA), nitric oxide (NO) and reactive oxygen species (ROS) were detected by nitrate reductase method and DCFH-DA probe, respectively. The protein and phosphorylation levels of ERK, JNK and p38 were measured by Western Blot method. After the cells pre-treated with the inhibitor of p38 (SB203580) were exposed to EMP, the levels of NO and ROS in culture supernatant were detected.

RESULTSIt was found that the large ameboid shape appeared in some microglia cells exposed to EMP for 1, 6 and 12 h. Moreover, the number of microglia cells with ameboid shape increased significantly at 1 h, 6 h and 12 h after EMP exposure compared with sham group (P < 0.05). The levels of cytokines, such as TNF-α, IL-1β and IL-10, in culture supernatant did not change obviously after EMP exposure. The levels of NO and ROS increased significantly at 1h after EMP exposure, reached the peak at 6 h, began to recover at 12 h and recovered to sham group level at 24 h (P < 0.05). Western blot results showed that the protein and protein phosphorylation levels of ERK and JNK did not change significantly after EMP exposure, however, the protein and protein phosphorylation levels of p38 increased obviously at 1 h and 6 h after EMP exposure, compared with sham group (P < 0.05). In addition, the pretreatment of p38 inhibitor (SB203580) significantly decreased NO and ROS production induced by EMP.

CONCLUSIONEMP exposure may activate microglia cells and promote the production of NO and ROS in mouse microglia cells, and p38 pathway is involved in this process.
