Objective:To observe the clinical effects of acupuncture plus external medicine application for cervical radiculopathy.Methods:A total of 98 patients with cervical radiculopathy were randomly divided into an observation group and a control group based on the random digital table.The observation group (50 cases) was treated by acupuncture plus external medicine application and the control group (48 cases) was treated by acupuncture alone.The patients received the treatment every day.Ten sessions made a course.Cervical spondylosis symptom scale was used to assess the cases before and after the treatment.The clinical efficacy was compared between the two groups after the treatment.Results:The total effective rate was 98.1％ in the observation group versus 87.6％ in the control group with a statistically significant difference between the two groups (P＜0.05).The cure rate was 52.0％ in the observation group versus 18.8％ in the control group with a significant difference between the two groups (P＜0.05).There was no significant difference in the score of cervical spondylosis symptom scale between the two groups before the treatment (P＞0.05).It increased with a significant difference in both groups after the treatment (both P＜0.05),while a significant difference was found in the results between the two groups after the treatment (P＜0.05).Conclusion:Acupuncture plus external medicine application is more effective than acupuncture alone for treating cervical radiculopathy.The method also effectively improves the clinical symptoms.

Objective To evaluate the safety and efficacy of 125I radioactive seeds implantation combined with postoperative chemotherapy as a treatment option for thoracic advanced esophageal squamous cell carcinoma(ESCC). Methods A prospective cohort study was carried out between 2000and 2005. According to preoperative CT staging criteria,298 patients in phase Ⅱ-Ⅲ of ESCC, who had were admitted to Oncology Center Surgery of Nanjing First Hospital Affiliated to Nanjing Medical University and Thoracic Surgery of YanCheng Oncology Hospital, were randomly divided into three groups: intraoperative 125I seeds implantation combined with postoperative chemotherapy (group A, 98cases), postoperative chemoradiotherapy (group B, 100 cases) and surgery alone (group C, 100cases). All patients received radical resection of esophageal cancer. According to pTNM staging criteria after operation, 233 patients in phase Ⅱb-Ⅲ of ESCC were finally enrolled in the study (78 in group A, 75 in group B, and 80 in group C). With 0. 5 m Ci of single seed, total activity of 5-11 mCi and matched peripheral dose in 60-70 Gy, 10-22 125I seeds were implanted into the target of patients in group A under direct vision in accordance with treatment planning system. The validation and quality assessment of radioactive seeds were demonstrated according to CT scan or X-ray imaging. The postoperative complications were observed. The local recurrence of the cancer was demonstrated using CT scan. The survival rate of patients was followed up for 1-,3-,5- and 10 years. Results The satisfied quality assessment of 125I seeds was observed. There was no displacement or loss of seed. The local recurrence in group A, B and C was 11. 5%, 13. 3% and 38. 8%, respectively, with statistical significance (P ＜ 0. 05). There was no significant difference among three groups with respect to complications and 1-year survival (P＞0. 05). However, the overall survival rate 3-, 5- and 10-years was 64.8%,37. 7% and 25. 1% in group A respectively; 63.3%, 36.9% and 24.9% in group Brespectively; 43. 6i%, 25.0%, and 12.6% in group C, respectively (all P＜0. 05). The 3-,5- and 10-year progression free survival rates were 63.5 %, 37.4 % and 15.1% in group A respectively; 62.5 %,36.6% and 14. 4% in group B respectively; 42.5%, 25.6% and 6.2% in group C respectively (all P＜0. 05). Conclusions It is a safe, effective and simple method for intraoperative 125I seeds implantation combined with postoperative chemotherapy in treatment of advanced ESCC, which may reduce the local recurrence and improve survival rates in patients with ESCC.

Purpose To study NF-κB gene expression level in mouse hepatocellular carcinoma cell lines with differently lymphatic metastasis potentials and to discuss its roles in lymphatic metastasis.Methods Using real-time quantitative PCR, NF-κB gene expression level was detected in mouse hepatocellular carcinoma cell lines, including Hca-P with low lymphatic metastasis potential and Hca-F with high lymphatic metastasis potential.Results NF-κB mRNA expression in Hca-P and Hca-F cell lines were (1.41±0.48)×10~(-3),and (2.95±0.22)×10~(-3) (P<0.01),respectively.NF-κB mRNA expression levels were increased with metastasis potential.Conclusion NF-κB gene may play an important role in lymphatic metastasis of hepatocellular carcinoma.

[Objective]To study the effect of curcumin on the cholesterol metabolism of nonalcoholic fatty liver disease(NAFLD) cells model induced in vitro and its potential mechanism. [ Methods]The cellmodel of nonalcoholic fatty liver disease(NAFLD) was established by oleic acid and treated with curcumin. The method of oil red O staining was used to observe accumulation of intracellular lipid while the intracellular content of TG, FC and TC was detected by enzymatic method. Meanwhile, the mRNA levels of SR-BΙand HMGCR were detected with qPCR.[ Results] The NAFLD cellmodel was successful y established by culturing with 30 μg·mL-1 oleic acid. After curcumin intervention, TG, FC and intracellular lipid accumulation levels were significantly reduced in NAFLD cellmodel. Meanwhile, curcumin can reduce HMGCR mRNA expression and raise SR-BΙ mRNA expression. [Conclusion] Curcumin can decrease FC level in NAFLD cellmodel and the mechanism might be related with its capacity of restraining endogenous cholesterol biosynthesis and promoting foreign cholesterol transfer into the liver cells for metabolism.
