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.

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 robe of interleukin-6 in the apoptosis of multiple myeloma (MM) cell lines KM_3 induced by melphalan and its molecular mechanism. Methods Apoptosis was confirmed by flow cytometry, DNA fragmentation rate and TUNEL. The expression of caspase-3, caspase-8 proteins in KM_3 cell, which was assessed by Western blot analysis, after melphalan treatment and cultured with or without interleukin-6. Results KM3 cells in the presence of interleukin-6 showed lower rate of apoptosis compared with that in the absence of interleukin-6 (P

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.

Objective: To investigate the influence of the expression of retinoic acid receptor genes on the development of B cells in lymph nodes of young children. Method: In situ hybridization was performed on the frozen section of lymph node of young children (≤age 5 ). Six digoxin labeled antisense RNA probes for retinoic acid receptors mRNA(RAR?、?、?、RXR?、?、?)were used. The expression and distribution of retinoic acid receptor genes in lymph nodes and their influence on the differentiation and maturation of B cell were observed. RT-fluorescent PCR was also used to observe the expression levels of retinoic acid receptor genes and their relation to the maturation of B cells. Results: In situ hybridization showed all the 6 retinoic acid receptor genes were expressed in lymphocytes and reticular cells of lymph node, and the distribution was widespread. RT fluorescent PCR also showed a varying expression of 6 retinoic acid receptor genes in lymph node among different age children, but lower in children younger than 1 year, and then increased gradually with the development of immune system. Conclusion: The expression and regulation of retinoic acid receptor genes may take part in the ontogenesis of B cells, and play a key role in the regulation of retinoic acid and enforce the anti-infective immunity in children.

Aim To investigate the effects of 4-aminopyridine (4-AP),K+ channel blocker, on the gastrointestinal function of murine. Methods Charcoal suspension was used to detect the effects of 4-AP on gastrointestinal motility of mice in vivo, contraction of isolated fundus longitudinal strips and duodenum of rats were studied in vitro,gastric acid secretion was measured by Gastric Secretion Test. Results 4-AP(5 mg?kg -1,ig)inhibited the gastrointestinal motility of mice. 4-AP(5 mmol?L -1) increased the maximum contractive force and minimum relaxation force, decreased the amplitude and frequency of the isolated duodenum peristaltic contraction. 4-AP(2.5 mg?kg -1,ip) significantly enhanced gastric acid secretion of rats. Conclusion 4-AP inhibited gastrointestinal motility and enhanced gastric acid secretion in murine.

Objective To investigate the influence of retinoic acid (RA) in differentiation,maturation and function of intestinal dendritic cells (DC),and probe into the effect of Vitamin A (VA) on intestinal mucosal immunity and pathway. Method Rat intestinal mucosa was cultured in vitro,supplemented with all-trans RA and/or retinoid acid receptor ? (RAR?) antagonist (Ro 41-5253). After cultured for 24h and 48h,the surface markers OX62、OX6 and CD86 on DCs were detected by flow cytometry,to observe the effect of RA on differentiation and maturation of DC. The cytokines and RAR? were measured in mRNA levels by RT-PCR to analyze the influence of RA on mucosal immunity and the pathway. Results RA promoted the maturation of DC in mucosa cultured in vitro,and up-regulated RAR? mRNA levels,the changes were marked at 24h. Moreover,when RA was present in the culture,IL-12 and IFN-? (Th1 cytokine) mRNA were reduced,and IL-10 was increased significantly compared with control . However,the actions of RA above can be inversed by Ro 41-5253. Conclusion The modulation of RA on DC could be one of the important mechanisms that VA influences intestinal mucosal immunity. RAR? participates in the regulation of RA on DC.
