Objective To explore an anatomical basis for the lateral tarsal artery pedicle flap on front and lateral compartment of leg and the feasibility of repairing skin defects on forepart of feet. Methods The branches, course and anastomosis of the lateral tarsal artery, perforator of peroneal artery up external malleolus, superficial peroneal artery were studied in 20 legs of adult cadavers.The flap was designed on these grounds. 8 cases repaired by lateral tarsal artery pedicle flap on front and lateral compartment of leg, 5 cases of skin defects on dorsum of foots, 3 cases of skin defects on footplates.The area of defect on forepart of foot was 5 cm× 4 cm-cm × 5 cm. The donor sites were resurfaced with skin grafts or sutured directly. The lateral tarsal artery, perforator of peroneal artery up external malleolus, perforator of anterior tibial artery superficial peroneal artery were anastomosed each other, formed single band blood vessel axle on lateral foot, fore external malleolus, front and lateral compartment of leg. The area of flap was 6 cm × 4 cm - 10 cm × 6 cm.Results All of the flaps survived completely. All cases were followed up, followed up 6- 12 months, averaged 8 months. The color, appearance and texture of the flaps were good, without ulcer on the flap. The patients can walk freely. Conclusion The flap on front and lateral compartment of leg should be designed according to the lateral tarsal artery. Blood supply of flap was reliable, little trauma. The flap's vessel pedicle is enough long. It could repair any defect on forepart of foots.

Objective To study the expression and prognostic significance of neuroendocrine differentiation markers chromogranin A(CgA)and synaptophysin(SYN) in patients with resectable non-small cell lung cancer(NSCLC).Methods From January 2000 to January 2003,123 patients with NSCLC who received operations were investigated.The resected specimens and clinical data were collected.Immunohistochemical Elivison method was used to detecte the expression of CgA and SYN.Kaplan-Meier survival curve and Cox proportional hazard model multivariate analysis were applied for the prognostic factors. Results The positive expression rates of CgA and SYN were 22%,17.9%,respectively.The expression of SYN was associated with histological differentiation(P=0.001).No significant association was found between NSCLC with neuroendocrine differentiation(NSCLC-ND) and sex,age,smoke index,TNM Stage and pathology classification.No evidence showed the patients with positive expression of CgA or SYN could be tolerant with more cycles of chemotherapy(P=0.406).Kaplan-Meier survival curve indicated the survival had a relation with the expression of CgA and SYN.It was revealed by Cox analysis that SYN(P=0.001),TNM stage(P=0.02)and the maximal diameter of tumor(P=0.049) were independent prognostic factors. Conclusion The patients with NSCLC-ND had a poorer prognosis.SYN may be one of the prognostic factors in patients with NSCLC.

Objective:To detect the expression levels of neuropilin1 (NRP1)mRNA and miR-9 in non-small cell lung cancer (NSCLC)tissue samples, and to explore the correlations between the expressions of NRP1 mRNA, miR-9 and the clinicopathological characteristics of the patients with NSCLC.Methods:Informed consent was obtained from each patient before surgery.The tissue samples including 45 NSCLC tissue ,45 adjacent carcinoma tissue and 45 normal lung tissue were collected from China-Japan Union Hospital of Jilin University from 2010 to 2011.qRT-PCR was used to detect the expression levels of NRP1 mRNA and miR-9 in three kinds of lung tissue, and the correlation between the expressions of NRP1 mRNA, miR-9 and clinicopathological characteristics of the patients with NSCLC was analyzed.Results:Compared with normal tissue,the expression level of NRP1 mRNA in adjacent carcinoma tissue had no change (P>0.05),but the expression level of NRP1 mRNA in non-small cell lung cancer tissue was significantly decreased (P<0.05).Compared with normal tissue,the expression level of miR-9 in adjacent carcinoma tissue had no change (P>0.05),but the expression level of miR-9 in non-small cell lung cancer tissue was significantly increased (P < 0.05 ). Furthermore, in adjacent carcinoma tissue, the expression level of miR-9 in the males was lower than that in the females (P<0.05 ). In NSCLC tissue, the expression level of NRP1 mRNA had no relationship with sex,age,differentiation degree,TNM stage and clinical stage,but was significantly correlated to the histological subtype and lymph node metastasis (P<0.05).In NSCLC tissue,the expression level of miR-9 had no relationship with age, pathological type, lymph node metastasis, differentiation degree,TNM stage,and clinical stage (P>0.05),but was correlated to the sex (P<0.05). Conclusion:The expression level of miR-9 is up-regulated and the expression level of NRP1 mRNA is down-regulated significantly in non-small cell lung cancer tissue. The detection of the expression level of NRP1 mRNA contributes to j udge the histological subtype and lymph node metastasis of NSCLC.

OBJECTIVETo observe the clinical efficacy difference between segmentation scraping and conventional acupuncture for cervical spondylosis (CS) so as to provide effective treatment method.

METHODSEighty-five cases of cervical type of CS were randomly divided into a scraping group (44 cases) and an acupuncture group (41 cases). The segmentation scraping therapy was used in the scraping group. The scraping group was treated with focusing on scraping the head and joint part of neck and occiput in the upper cervical spine injury, and focusing on scraping the lower section of cervical and shoulder in the lower cervical spine injury, once every seven days, totally for 3 times. In the acupuncture group, Fengchi (GB 20),Wangu (TE 5), Tianzhu (BL 10),Neck-Jiaji (EX-B 2), etc. were selected,once daily,for 15 days. The visual analogue scale (VAS) was used to evaluate the immediate analgesic effect after the first treatment and the clinical efficacy was observed after the end of treatment.

RESULTSAfter the first treatment, the score of VAS was decreased significantly in the scaping group (P < 0.01), but there was no significant difference in the acupuncture group compared with those before treatment (P > 0.05); the score of VAS in the scaping group after the first treatment was lower than that in the acupuncture group (3.66 +/- 0.74 vs 5.43 +/- 0.35, P < 0.01). Compared with before treatment, the scores of VAS were decreased significantly after treatment in two groups (both P < 0.01), but without significant difference between two groups (P > 0.05); the effective rate was 95.5% (42/44) in the scaping group and 87.8% (36/41) in the acupuncture group, the curative effects were similar (P > 0.05).

CONCLUSIONBoth of scraping and acupuncture therapies have good analgesic effect for cervical spondylosis, and overall effects are similar, but the immediate analgesic effect of scraping thrapy is better than that of conventional acupuncture.
