OBJECTIVE:To observe the clinical efficacy of acupoint application of antiemetic cream in the treatment of che-motherapy-induced nausea and vomiting. METHODS:90 cases of non-small cell lung cancer(NSCLC)(stage Ⅱ to Ⅲ)treated by chemotherapy(taxol+cisplatin)were randomly divided into antiemetic cream group,Weifuan group and control group,with 30 cas-es in each groupby drawing lots. Control group was given intravenous injection of ondansetron hydrochloride 8 mg 30 min before chemotherapy;antiemetic cream group was additionally given acupoint application of antiemetic cream 30 min before medication on first-forth day on the basis of control group;Weifuan group was additionally given acupoint injection of metoclopramide(brand name:Weifuan) 30 min before medication on first-forth day on the basis of control group. The clinical efficacy of 3 groups were observed during and 3 days after chemotherapy. RESULTS:After chemotherapy,the total control rates of antiemetic cream group (93.33%)and Weifuan group(90.00%)were apparently higher than the control group(66.67%),with statistical significance(P<0.01 or P<0.05);The total effective rates of TCM syndrome in antiemetic cream group (90.00%) and Weifuan group(83.33%) were apparently higher than in control group(60.00%),with statistical significance(P<0.01 or P<0.05). Therapeutic efficacy of antiemetic cream group was similar to Weifuan group,without any statistical significance(P>0.05). However,8 patients had obvi-ously pain at the injection site in Weifuan group,but tolerated to the drugs basically. CONCLUSIONS:The acupoint application of antiemetic cream combined with intravenous injection of ondansetron is effective and easy to operate in the treatment of nausea and vomiting induced by chemotherapy for stage Ⅱ to Ⅲ of NSCLC without pain,scar and sequela,and easy to be accepted by patients.

Objective To study the distribution of intestinal autofluorescent microorganisms in the rat intestine at different developmental stages. Methods The distribution of intestinal autofluorescent microorganisms in rat intestine at va-rious developmental stages was tested and evaluated using a small animals living imaging system. First, standard E. coli strain was tested by fluorescence detection in vitro. Then, the distribution of E. coli under the same test conditions was tested. The intestinal autofluorescent bacteria distribution was detected in the SD rats at 3 days,14 days and 60 days of age. After expanding the range of excitation wavelength fluorescence detection,removing the background of fluorescence feed and feces and other foreign autofluorescent substances. Results E. coli can be excited in the range of 485 -535 nm wave?length and to emit fluorescence. E. coli mainly existed in the stomach and only a few E. coli were found in the ileum of 3?days old SD rat. . In the 14?days old rats, E. coli mainly existed in the stomach and cecum, and only a few E. coli were found in the ileum. In the 60-days old SD rats, E. coli mainly existed in the ileum, and only a few E. coli were found in the colon, cecum and jejunum. After the expansion of the excitation light wavelength range of fluorescence detection, E. co?li were observed mainly in the ileum, and only a few E. coli were found in the stomach in 3?days old SD rat. E. coli mainly existed in the stomach, then the cecum and only a few E. coli were found in the ileum and jejunum in 14-days old SD rats. E. coli could be found in the whole intestinal system but mainly in the ileum and cecumin of the 60-days old rats. Conclu?sions Examining the intestinal autofluorescent microbes with the small animal in vivo imaging system can be helpful and make guidance to study the distribution of intestinal microbes in the host at different developmental stages, and to provide a basis for studying the relationship of intestinal microbes with its host and the gastrointestinal drug administration.

Objective To explore the method of culture of rat adipose-derived stem cells(ADSCs) and differentiation induction into myoblasts. Methods Adipose tissues were obtained from SD rats,and were isolated by enzyme digestion and cultured into ADSCs.The expression of surface antigen CD90,CD105 and CD34 was detected by immunofluorescence and flow cytometry.ADSCs of the second passage with logarithmic growth were obtained,and culture media containing 5-azacytidine(5-aza) and basic culture media were employed for cells in induction group and control group,respectively.The induction lasted for 7 d,14 d,21 d,28 d and 35 d,respectively.Cell growth and cell morphology were observed by inverted phase contrast microscope,and immunofluorescence and flow cytometry were utilized to detect the expression of myoblast specific antigens desmin and myosin. Results ADSCs were successfully isolated and cultured,and were identified to be stem cells.On the 28th day of induction,cells in induction group displayed "swirl" morpholgy,and multinucleation was observed.It was revealed by immunofluorescence and flow cytometry that the highest expression rates of desmin and myosin were 52.57% and 50.04%,respectively on the 28th day of induction,while there was no expression before induction and in control group. Conclusion ADSCs can be isolated and cultured from rat adipose tissues,and can further differentiate into myoblasts after induction by culture media with 5-aza.The expression of myoblast specific antigen is the highest on the 28th day of induction.

Objective To explore the effect of different indexes on evaluating insulin resistance in obese children. Methods Oral glucose tolerance test (OGTT) was performed in obese children (n= 61) and age - matched normal volunteers( n= 23) Serum glucose and insulin levels were determined at 0,30,60,120,180 min after OGTT, insulin resistance was estimated by homeostasis model assessment of insulin resistance (HOMA-IR). Indexes such as the ratio of area under the curve of glucose(AUCG)/area under the curve of insulin(AUCI), the ratio of fasting blood sugar(FBG) and fasting blood insulin (FINS) were meanwhile calculated. Results The level of serum FINS was significantly higher in obese children(P

BACKGROUND: Because of the prevalence of diabetes, the treatment of diabetic foot is still challenging. Even an exactly proved effective and practical method can't be listed except vascular surgery which is not a long-term way for it. Spinal cord stimulation (SCS) is a very promising option in the treatment algorithm of inoperable chronic critical leg ischemia (CLI). DATA SOURCES: We searched Pubmed database with key words or terms such as "spinal cord stimulation", "ischemic pain" and "limb ischemia" appeared in the last five years. RESULTS: The mechanism of SCS is unclear. Two theories have emerged to interpret the benefits of SCS. Pain relief from SCS can be confirmed by a majority of the studies, while limb salvage and other more ambitious improvements have not come to an agreement. The complications of SCS are not fatal, but most of them are lead migration, lead connection failure, and local infection. CONCLUSIONS: SCS is a safe, promising treatment for patients with inoperable CLI. It is effective in pain reduction compared with traditional medical treatment.

Objective To evaluate the efficacy and safety of recombinant adenovirus-p53 (rhAd-p53) combined with neoadjuvant chemotherapy in treatment of locally advanced cervical cancer.Methods Forty patients with stage Ⅰ R2-Ⅲ A locally advanced cervical cancer were randomly divided into 2 groups,gene therapy + neoadjuvant chemotherapy group (rhAd-p53+PVB group,n =20.They received one course of chemotherapy consisting of PVB.rhAd-p53 solution 1 ×1012 VP was injected intratumorally every three days for three circles since the 3rd day of PVB chemotherapy) and chemotherapy group (PVB group,n=20,the above course of chemotherapy was conducted).The volums of tumors was observed.Patients were monitored for adverse event.The expression of VEGF,p53 pertein and MVD in tumor tissue was detected by immunohistochemistry.Results The evaluation was performed three weeks after the completion of chemotherapy.The PVB group response rate (CR+PR) was 75 ％,while the effective rate was 95 ％ of the PVB combined with gene group.After using of the PVB chemotherapy,the tumor was shrunk by (11.42±2.78) cm2.However,the volums of tumor were significantly shrunk by (15.25±4.00) cm2 using the PVB combined with gene therapy,and P ＜ 0.05.The positive expression rate of VEGF,p53 protein and MVD were reduced respectively in PVB group and rhAd-p53 + PVB group with statistic significance.There were no additional adverse events by recombinant adenovirus-p53 combined with neoadjuvant chemotherapy.Conclusion A potentially gene therapeutic agent for cervical cancer treatment,intratumoral injection of rhAd-p53 is effective.

Objective To investigate the production path of major histocompatibility complex class Ⅰ chain-related gene A(MICA) antibodies and the impact on the therapeutic efficacy after acute rejection in renal transplantation recipients.Methods Luminex flow cytometry was used to detect antiMICA antibodies and the antibody specificity in 157 pre-transplant kidney transplant recipients randomly selected.The clinical data were collected,anti-MICA antibody production pathway and immunoglobulin types were analyzed,and the impact of IgM anti-MICA antibody and IgM&IgG complex anti-MICA antibodies on acute rejection (AR) incidence and therapeutic efficacy after renal transplantation.Results Of the total 157 recipients,19 recipients were positive for anti-MICA antibodies before renal transplantation in 68 recipients who had history of blood transfusion,pregnancy and transplant sensitized experience (27.9％ ); In 89 recipients having no sensitized experience,MICA antibodies were positive in 26 recipients (29.2％ ) (P＞0.05).In 45 anti-MICA antibody-positive recipients,the anti-MICA antibodies type was IgM in 26 cases having no sensitized experience; and that was IgG and IgM complex in 19 cases having sensitized experience.In 38 antiMICA antibody-positive recipients undergoing kidney transplantation,7 out of 22 IgM anti-MICA antibodies recipients had AR (31.8％) that was reversed by methylprednisolone pulse therapy,and 7out of 16 IgM&IgG complex anti-MICA antibodies recipients had AR (43.8％) and treated with methylprednisolone pulse therapy:reversion in 3 recipients (42.9％),and the graft function loss in 4 recipients.The AR incidence was not associated with the two immunoglobulin types of MICA antibodies(P＞0.05),but there was significant difference in the reversal rate of AR (P＜0.05).Conclusion For non-allergenic history recipients,there exists the classic “natural antibodies” pathway in the production of the anti-MICA antibodies whose immunoglobulin type was IgM.In addition,the reversal effect of AR in recipients with IgM anti-MICA antibodies was much better.We need to attach importance to IgM&IgG complex anti-MICA antibodies for the pre-transplant anti-MICA antibodies in renal transplant recipients,because their AR treatment outcome is poor.

Aim To screen a more suitable transfection recep-tor,and improve the efficiency of constructing cell lines highly expressing human peptide transporters 1 (hPepT1 ).Methods The recombinant plasmid pcDNA3.1 (+)-hPepT1 was transfect-ed into MDCK cells and HeLa cells by LipofectamineTM 2000 transfection reagent,respectively.The monoclonal cells were se-lected and cultured.Expression of hPepT1 mRNA and protein were determined by qRT-PCR and Western blot,respectively. The uptake capacity of Glysar in transfected cells was examined. Results Compared with wild type cells,the expression of hPepT1 and the uptake of Glysar in transfected MDCK cells and HeLa cells significantly increased (P <0.05).Although the up-take of Glysar in HeLa cells was higher than that of MDCK cells,on the contrary,the expression of hPepT1 and the uptake of Glysar in MDCK-hPepT1 cells was higher than that of HeLa-hPepT1 cells.Conclusion MDCK cells may serve as a more suitable transfected receptor for the construction of a cellular model with high expression of hPepT1 ,which would make the construction of a cell model highly expressing hPepT1 more effi-cient.
