Objective To observe the effect of acupuncture at Tianzhu (BL10) on Blood Stasis Type lumbar disc herniation (LDH). Methods From October, 2013 to October, 2015, 108 LDH cases were randomized into observation group (n=53) and control group (n=55) in accordance with the order of visiting. The observation group received Tuina and acupuncture mainly at Tianzhu, while the control group only received Tuina, for four weeks. The clinical efficacy and improvement of Japanese Orthopaedic Association (JOA) scores were record-ed, and the Visual Analogue Scale (VAS) and serum levels of interleukin-6 (IL-6) were measured before and after treatment. Results The VAS score and IL-6 content decreased in both groups after treatment (t>4.220, P<0.001), and decreased more in the observation group than in the control group (t>3.745, P<0.001). The total effective rate was 94.34% in the observation group, more than 81.82% in the control group (χ2=3.997, P=0.046). The incidence of impromvement of JOA scores was 90.57%in the observation group, more than 76.36%in the control group (χ2=3.920, P=0.048). Conclusion Acupuncture at Tianzhu based on Tuina is more effective on Blood Stasis Type lumbar disc herniation, in term of pain and function, which may relate with decrease of the level of IL-6.

In order to explore the relationship between the expression of TGF ? 1,its receptor and the wound age during the healing process of rats skin incision wound,a preliminary study were performed on the vital skin wound 0 5～168h after injury by using the immunohistochemical and the molecular biological methods.The results were then compared with those of the postmortem skin injury.The results revealed that the expression of the cytokine TGF ? 1 in the epithelial cells were enhanced 0 5h after the antemortem skin incision and the strongest reactions were seen at 24～96h post injury.The expression of TGF ? 1 was also found in the macrophages and the fibroblasts in the granulation tissues.Analysis of the immunoblotting(Western blot)results showed that the peak value of the TGF ? 1 protein was appeared at 168h after the antemortem skin incision and peaked at 96h.TGF ? 1 was detected 0 5～3h after postmorten skin injury by using the immunohistochemical method.No expression of mRNA was found.It is suggested that some regular and characteristic expression of TGF ? 1 in the incised skin wounds were related with the wound age.It might be used for timing of skin wound on rat.

Objective To study the effect of different doses of atorvastatin in the treatment of coronary heart disease with chronic heart failure. Methods 100 patients with chronic heart failure who were admitted to Ankang Hospital from April 2013 to April 2016 were selected and randomly divided into the experimental group and the control group with a total of 50 patients in each group. Two groups of patients were treated with conventional treatment, the control group was given 20 mg of calcium a day, the experimental group was given a daily dose of 40 mg of calcium. The therapeutic effects of the two groups were compared. Results After treatment, the left ventricular end diastolic diameter in the control group was significantly higher than that in the experimental group, the left ventricular ejection fraction and E/A were significantly lower than those in the experimental group, and the difference was statistically significant (P<0.05). Patients in the control group were significantly higher than those in the experimental group in the incidence of cardiac death and recurrence of heart failure (P<0.05). Before treatment, there was no significant difference between the experimental group and the control group in serum NT-proBNP, hs-CRP levels and 6MWT. After treatment, the serum levels of NT-proBNP, hs-CRP in the control group were significantly higher than those in the experimental group, 6MWT was significantly shorter than that in the experimental group, and the difference was statistically significant (proBNP) (P<0.05). Conclusion Compared with 20mg/d, 40mg/d dose atorvastatin in the treatment of coronary heart disease with chronic heart failure curative effect, low recurrence rate, high safety, worthy of further promotion in clinical.

Camptothecin is known to possess a broad spectrum of anticancer activities, however due to its high toxicity and low solubility in water, camptothecin is severely limited in clinic. To optimize the effects of camptothecin in the treatment of malignancies, besides the structural modification and reconstruction of camptothecin, the establishment of new drug delivery systems becomes a hot topic in the camptothecin research. This paper aims to summarize the advanced progress in the delivery system and function of camptothecin at recent years. The advances in improving the poor solubility, lactone ring instability, controlled release systems and targeting delivery systems of camptothecin are also reviewed. As the related methods and technologies are improved and developed, camptothecin will be a group of prospective anticancer drugs.

Objective To explore the digital morphological and chromatic characteristics of erythrocytes infected with Plasmodium vivax. Methods The images of both normal and P. vivax infected erythrocytes were segmented and measured for morphologic parameters including area, length, breadth, perimeter, roundness, aspect ratio, equivalent circle diameter, as well as chromatic parameters including saturation and color (red, green, blue). A statistic analysis was performed for these parameters. Results Both morphological and chromatic parameters showed high significant differences between the normal and the infected erythrocytes, and high significant differences between the normal and the erythrocytes infected with different stages of P. vivax. Conclusion The differences mentioned above could be used as the basis for automatic identification of P.vivax in thin peripheral blood smears.

Methods 187 cases were treated by anal pad-preserving ligation resection, while 77 cases by routine procedures of stripping off the varicose masses of the external hemorrhoids and ligation the internal one as the control. Results Healing time of the operative wound were (17?4)d in the the study group and (24?4)d in the controls respectively( t =9.24, P 0.05). Postoperative urinary dysfunction: 14.4% of cases developed in the study group and 27.3% in the controls(? 2=8.42, P

Objective: To investigate the effect of retinoic acid on the differentiation and development of B lymphocytes, and explore the mechanism of vitaminA in increasing the production of antibodies. Method: In vitro cultured cells from children’s normal mesentery lymph nodes, before and after administration of retinoic acid or retinoic acid antagonist, the changes of cell surface markers were analyzed by flowcytometry to observe the differentiation and maturation of B cells. Results: During culture in vitro, the percent of mature CD19+IgM+ B cells increased and relatively immature CD19+IgM- B cells decreased gradually, and the changes were especially obvious at 48 h. The administration of retinoic acid further increased the percent of CD19+IgM+ B cells, and the enhancement was markedly at 24 and 48 h (P

Objective To research the early effect and side effect on the radiotherapy of nasopharyngeal carcinoma patient using IMRT compared with conventional radiotherapy. Methods Seventy eight nasopharyngeal carcinoma patients were divided into IMRT group (38 patients) and conventional radiotherapy group (40 patients). After CT-sim, the radiation oncologist and physician delineated the outline of GTV, CTV, parotid gland, spinal cord and brain stem. The receiving volume of parotid, spinal cord and PTV was respectively calculated by using inversing plan. Face-neck, supracalvicular field, amte-aural field and postaural field were adopted to receive electrons during conventional radiotherapy. Seven to nine conformal fields including 80-100 sub-fields were adopted during IMRT. The reaction of skin, parotid (xerostomia) and oral mucosa were recorded during radiotherapy. Results The nasopharyngeal and para-nasopharyngeal lesions regressed completely after radiotherapy. The volume received by the parotid, spinal cord and PTV was 30%?4.8, 56%?6.7, 95%?8.6, 92%?8.1 respectively in IMRT group, and 98%?9.4, 56%?10.7, 100%?9.7, 99%?9.5 respectively in conventional radiotherapy group. The received volume of parotid in IMRT group was significantly lower than in conventional radiotherapy group. The reaction of skin was grade I in IMRT group and grade II, III in conventional radiotherapy group. The reaction of parotid (xerostomia) was grade I and II in IMRT group and grade II and III in conventional radiotherapy group. The reaction of oral mucosa was grade I to II in IMRT group and grade II and III in conventional radiotherapy group. The reactions of skin and parotid (xerostomia) were lighter in IMRT group compared with those in conventional radiotherapy group. The time of radiotherapy was 45?4.4 days in IMRT group and 51?5.3 days in conventional radiotherapy group respectively. Conclusion The radiotherapy using IMRT regime can decrease the reaction of parotid (xerostomia) and skin to complete the radiotherapy course of nasopharyngeal carcinoma patients. Moreover, it can increase the life quality in nasopharyngeal carcinoma patients after radiotherapy and also shorten the time of radiotherapy.

Objective To explore the relation between changes in apurinic/apyrimidinic endonuclease (APE1) gene expression and effects of melphalan on multiple myeloma (MM) cells. Methods Expression of APE1 protein was detected in MM cell line KM3 using immunocytochemical staining and Western blot assay after 0~15?mol/L melphalan treatment for 1~2d. Integral optical density was determined by means of image analysis system. Results There was positive relationship between levels of APE1 protein in KM3 cells and the treatment time and dose of melphalan. Conclusion Expression of APE1 protein could be induced by melphalan treatment. The result suggests that a high expression of APE1 protein may play a certain role in the resistance of multiple myeloma to melphalan.
