Objective To study the effect of Chinese medicine fumigation bath combined with acupuncture and hemorrhoids on improving the pain edema of elderly patients after anorectal pain.MethodsA total of 168 elderly patients with anorectal surgery were enrolled in our hospital from April 2013 to April 2016.The patients were randomly divided into two groups: the group (n=84) and the conventional treatment group (n=84) N=84).Routine treatment group given conventional Western medicine and potassium permanganate solution bath treatment, fumigation acupuncture group on the basis of conventional Western medicine treatment to give Chinese fumigation bath and acupuncture hemorrhoids treatment, compared the two groups of clinical efficacy, pain, Wound recovery and skin adverse reactions.ResultsThe total effective rate, no pain rate, edema disappearance time and wound healing time were 94.0%, 38.1%, (5.13±1.59) d, (16.47±4.06) d, respectively, compared with those in the conventional treatment group 84.5%, 22.6%, (6.74±1.23) d, (19.38±3.75) d, the difference was statistically significant (P<0.05).ConclusionChinese medicine fumigation bath combined acupuncture hemorrhoids acupuncture points can improve the local blood circulation, anti-bacterial anti-inflammatory pain, relieve senile patients after anorectal pain edema symptoms, speed up the rehabilitation process.

Objective To study the effects of 900 MHz electromagnetic field(EMF)on DNA and the protein expression of p53 gene in human embryonic lung cells.Methods Single cell gel electrophoresis(SCGE)and Western Blot were used for the research.Results The results showed that 900 MHz EMF could not damage the DNA of human embryonic lung cells when the exposure time was 1 h and the exposure doses were 1,2,5 and 8 mW/cm2 respectively;900 MHz EMF could not affect the protein expression of p53 gene in human embryonic lung cells when the exposure time was 12 h and the exposure doses were 1,2,5 and 8 mW/cm2 respectively.Conclusion At the exposure doses in the present research,900 MHz EMF neither can damage the DNA of cells,nor can affect the protein expression of p53 gene,so the results can not sustain the issue that 900 MHz EMF may cause cancer.

Objective To observe the efficacy of CTLA-4Ig gene local transfection on the survival of renal allografts. Methods The kidneys of BN rats were transfected with CTLA-4Ig gene-recombined adenovirus. The transfected kidneys were transplanted to Lewis rats (transfection group). BN→Lewis kidney transplantation with non-transplanted kidneys served as controls. The allograft survival time and the allograft function between the two groups were compared. Results The allograft survival time of transfection group was longer than that of controls significantly (32? 8.0?days vs 8.5 ? 1.4?days , P

Objective To investigate effects of co-grafts of bone marrow stromal cells (BMSCs) combined with nerve growth factor (NGF) suspension on repair of spinal cord injury (SCI) in adult rats so as to determine whether the co-grafts are more effective than a single protocol.Methods Spinal cords of adult rats (n=32) were injured by the modified Allen's method.One week after injury,the injured cords were injected with Dubecco-modified Eagles Medium,BMSCs,NGF,and BMSCs plus NGF respectively.One month and two months after injury,rats were respectively sacrificed-and their injured cord tissues were sectioned to identify the transplanted cells under fluorescent microscopy.We observed axonal regeneration and differentiation of BMSCs through immunocytochemical staining conducted with neurofilament (NF) and Neuron-Specific Nuclear Protein (NeuN) and glial fibrillary acidic protein (GFAP).We measured the cavity volume by staining with hematoxylin-eosin (HE).At the same time,rats were subjected to behavioral tests using the open-field BBB (blood brain battier) scoring system.Results One month and two months after transplantation,immunocytochemical staining showed that transplanted cells partially expressed NeuN and GFAP.At the same time,significant reduction in lesion area (P＜0.05) and improvement in BBB lo- comotor rating scale (P＜0.05) were observed in the cases that received implantation,as compared with those that received vehicle injection.More importantly,further reduction in lesion area and improvement in function were ob- served in the combined treatment group.Conclusions BMSCs can differentiate into neurons and astroeytes. BMSCs and NGF can reduce lesion size,promote axonal regeneration and improve functional recovery,and may have a synergistic effect.

Objective To investigate the hemodynamics and structural effect of rat endothelial progenitor cells (EPC) transplant on pulmonary artery hypertension (PAH) induced by monocrotaline(MCT) in rats.Methods EPCs were identified and marked.Twenty-one days after injection of EPCs,the pulmonary hemodynamic parame- ters,average pulmonary artery pressure (mPAP),right heart index were determined.The vascular endothelial cells and pulmonary vascular structural changes were verified by fluoresccuse microscope.Results Compared with the model,EPCs treatment(n=10) decreased mPAP significantly (mPAP,EPCs:25.9?0.7 mmHg vs model group:29.3?2.2 mmHg,P

The study aimed to establish a population pharmacokinetic/pharmacodynamic (PPK/PD) model of warfarin. PCR-RFLP technique was used to genotype the CYP2C9 and VKORC1 polymorphisms of 73 patients. RP-HPLC-UV method was used to determine the 190 plasma concentrations of warfarin. Application of NONMEM, the clinical information and 263 international normalized ratio (INR) monitoring data were used to investigate the effect of genetic, physiological, pathological factors, other medication on clearance and anticoagulant response. The final model of warfarin PPK/PD was described as follows: CL = θCL · (WT/60)θWT · θCYP · eηCL (if CYP2C9*1/*1, θCYP = 1; if *1/*3, θCYP = 0.708); EC50 = θEC50 · θVKOR · eηEC50 (if VKORC1- 1639AA, θVKOR = 1; if GA, θVKOR = 2.01; V = θV; K(E0) = θK(E0); Emax = θEmax; E0 = θE0 · eηE0. Among them, the body weight (WT), CYP2C9 and VKORC1 genotype had conspicuous effect on warfarin PK/PD parameters. The goodness diagnosis, Bootstrap, NPDE verification showed that the final model was stable, effective and predictable. It may provide a reference for opitimizing the dose regimen of warfarin.

Objective To investigate the environmental quality and water quality of bathing beach in Haikou,Hainan province and the effects on human health.Methods The investigation of the bathing beach environment and the water quality were conducted according to Bathing Beach Monitoring Regulations(2002).The water samples were collected at PM 3:00-5.00 on May 28th to June 3th in 2007 from three sampling sites,No.1(easily be polluted),No.2(crowded),No.3(less pollution).The questionnaire survey was conducted on the present day and 7 days later,the items included the respiratory,digestive systems infection and eye,ear,nose and skin inflammation,the survey was completed in two days.Results The environment survey of bathing beach suggested that non-point source pollution caused by domestic wastewater emerged on raining days,the salinity was 31‰-33‰,clarity exceeded 30 centimeter and no heat pollution was found.The pH value,chroma,dissolved oxygen,nitrate nitrogen,chemical oxygen demand,inorganic nitrogen,fecal coli group was 8.01-8.10,11.42-15.00 NTU,5.60-6.71 mg/L,0.16- 0.17mg/L,2.70-3.40mg/L,0.19-0.21 mg/L and 35.0-36.0/L respectively.Four hundred and eight questionnaires were eligible, the response rate was over 90%.The results demonstrated that the swimmers were facing to the increased illness risk from the water quality,such as skin pruritus,gastrointestinal allergies,throat sore,eye and ear and nose infections.There was distinct higher proportion in the participants with water contact and complained one or more symptoms than those without water contact(P

Objective To identify the expression pattern of IGF-1 and IGF-1R in NK/T-cell lymphoma (NK/TCL) cell lines and to investigate the role of IGF-1/IGF-1R signaling in regulation of cell migration and invasion.Methods RT-PCR and immunofluorescence were performed to detect the expression of IGF-1 and IGF-1R.Transwell assay was applied to observe the effects of IGF-1/IGF-1R signaling and downstream kinases activities on cell migration and invasion.Concentrations of MMP-2 and MMP-9 were quantified by ELISA.Results Co-expression of IGF-1 and its receptor IGF-1R were identified in two NK/TCL cell lines,SNK-1 and SNK-6,while normal NK cells lack the IGF-1R expression.IGF-1R inhibitors significantly reduced SNK-1 and SNK-6 cells migration and invasion rates.Exogenous IGF-1 promoted both cell lines migration and invasion,but these effects were both blocked by IGF-1R inhibitors.Inhibition of AKT,p38 and JNK,the possible IGF-1R downstream kinases,reduced cell migration rates.Further more,exogenous IGF-1 significantly increased MMP-2 and MMP-9 secretion,while decreased secretion of MMP-2 and MMP-9 were observed when IGF-1R inhibitors were applied.Conclusion An autocrine IGF-1/IGF-1R signaling loop is aberrantly expressed on NK/TCL cells and the autocrine loop significantly promotes cell migration and invasion through activation of p38,PI3K and JNK signaling and enhances secretion of MMP-2 and MMP-9.

Objective To further elaborate the clinical characteristics,diagnosis,treatment and prognosis of primary cutaneous invasive epidermo-tropic CD8 positive cytotoxicity T-cell lymphoma.Methods The clinical characteristics,diagnosis and treatment of a patient with primary cutaneous invasive epidermotropic CD8 positive cytotoxicity T-cell lymphoma were summarized,and diagnosis and treatment of the disease from published literature were reviewed.Results After one year long,recurrence of exudative maculopapule on his body and limbs,a middle-aged male patient visited our hospital.Then,the patient was diagnosed as T2N0M0 Ⅰ phase of primary cutaneous invasive epidermo-tropic CD8 positive cytotoxicity T-cell lymphoma based on results of skin biopsy,immunohistochemistry,T-cell gene rearrangement and PET-CT.Through integrative medicine treatment (combination of bruceolic oil emulsion and chemotherapy with GDP regimen),the patient achieved complete remission (CR).The treatment and follow-up continues till now and his condition was stable.Conclusions Clinical occurrence of primary cutaneous invasive epidermo-tropic CD8 positive cytotoxicity T-cell lymphoma is rare and early diagnosis is difficult.It could be diagnosed with histopathology combined with T-cell gene rearrangement.In order to avoid misdiagnosis,great caution should be taken during disease history inquiry and physical examination,should be early lesion for delayed healing of recurrent lesions,biopsy should be conducted as soon as possible and immunohistochemistry should be performed simultaneously,which will provide a good basis for further treatment.

Objective To explore the therapeutic potential and mechanism of stem cells mobilized by granulocyte colony-stimulating factor (G-CSF) and AMD3100 to repair global cerebral ischemia injuries in a rat model of cardiac arrest (CA) and cardiopulmonary resuscitation (CPR).Methods Cardiac arrest was induced by asphyxia.Fifty-six SD rats were randomly assigned into four groups:G-CSF group,G-CSF + AMD3100 group,CPR control group and sham operated group.The animals were sacrificed at 3d and 6d after CPR respectively.The neurological status and morphological changes of damaged cerebrum,the apoptosis of nerve cells and vascular endothelial growth factor (VEGF) expressed in brain tissue and capillary density in hippocampus and temporal lobe cortex were measured and analyzed by means of neurological deficit score (NDS),adhesive tape removal test (TRT),ELISA,MRI and immunofluorescence.Results NDS in G-CSF + AMD3100 group (61.4 ± 10.7) was significantly higher than that in CPR control group (49.9 ± 10.4) at 3 d after CPR (P ＜0.05).And less time consumption for TRT found in G-CSF + AMD3100 group (85.5 ±28.9) s rather than was in CPR control group (148.1 ± 23.8) s and G-CSF group (118.5 ± 30.4) s (P ＜ 0.05).The severity of cerebral injury assessed by MRI was significantly milder at both 3 d and 6 d in the two stem cell mobilization groups.The apoptosis rate of nerve cells in G-CSF + AMD3100 group (0.23 ± 0.06) was significantly lower than that in G-CSF group (0.34 ±0.08) at 3 d after CPR,and that in both stem cell mobilization groups was lower than that in CPR control group (0.44 ± 0.09) (P ＜ 0.05).At 3 d and 6 d after CPR,the levels of VEGF in brain tissue were (106.2 ±23.3) pg/mL and (79.9 ± 18.4) pg/mL in G-CSF + AMD3100 group,and were (50.6 ± 13.7) pg/mL and (73.9 ± 16.6) pg/mL in G-CSF group,which were both significantly higher than that in CPR control group (23.1 ± 10.2) pg/mL and (36.2 ± 12.8) pg/mL (P ＜0.05).At 3 d after CPR,the cerebral capillary density (351.8 ±67.9) branches in every high power field (A/HPF) was significantly higher in G-CSF + AMD3100 group than that (301.4 ± 77.3) A/HPF in G-CSF group and (250.4 ± 48.0) A/HPF in CPR control group (P ＜ 0.05).The cerebral capillary density in G-CSF group elevated to (348.4 ±76.7) A/HPF at 6 d after CPR which was significantly higher than that at 3 d (P ＜0.05),and there was no difference between that at 3 d and 6 d in G-CSF + AMD3100 group.Conclusions The mobilization stem cells improve the impaired neurological function.The increased expression of VEGF in brain tissue,the neo-vascularization promoted by the mobilized stem cells and the inhibition of nerve cell apoptosis may be associated with the protective effects of the stem cell mobilization.
