Chinese Journal of Primary Medicine and Pharmacy 2010;17(23):3175-3177
Objective To study the value of neoadjuvant chemotherapy in the treatment of cervical carcinoma. MethodsA clinical prospective study was carried out from Jan.1997 to Dec.2003,118 patients with cervical carcinoma were given two cycles of combined chemotherapy before operation(neoadjuvant chemotherapy group,group A).102 patients accepted surgery alone in our hospital from Jan.1997 to Dec.2003 were chosen as the comparison group(group B).Survival rate and complications were observed and analysed. Results5 year survival rate in group A was significantly higher than that in group B(P<0.01),The 5 year survival rate was significantly higher in group A than in group B,despite of different pathological types,with or without radiochemotherapy(P<0.05).The recurrent rate was lower in group A than that in group B,which show significant difference in the 5 year recurrent rate(P<0.05). ConclusionNeoadjuvant chemotherapy is an effective method for the treatment of cervical carcinoma in early stage.Because of satisfactory short-term control rate,excision rate,long-term survival rate and low recurrent and metastatic rate,neoadjuvant chemotherapy is worth popularizing in clinical treatment.

OBJECTIVE:
To discuss the clinical features and treatment methods for simple orbital blowout fracture.
METHOD:
Retrospective analysis of the CT images of 16 orbital blowout fracture case, and identification of the sites, degree, patterns and features of fractures. Among the 16 cases, 2 cases adopted conservative treatment; 11 cases gained a reduction of orbital fracture through endoscopic transnasal surgery; the other 3 patients choosed endoscopic transnasal surgery and Caldwell-Luc operations.
RESULT:
Among 16 diplopia cases, 13 cases were completely cured, and 3 patients' vision were significantly improved. Among 11 enophthalmos cases, 10 patients were cured, and the effect of the other one was not satisfied. Among the 15 eye movement disorder cases, 13 patients' eye movement gained a full recovery, and the other 2 cases were nearly normal. All patients' vision were improved in different extents, and no one got a complication.
CONCLUSION
Computerized Tomography is helpful to the diagnosis of simple orbital blowout fracture. Caldwell-Luc operation with transnasal endoscope is an effective method for the treatment of orbital fractures.

Objective: To study the feasibility of percutaneous absorption of Compound Patch of Hyperosteogeny(CPH). Methods: The content of ferulic acid,an index composition in percutaneous receptor fluid and release receptor fluid were determined by HPLC.Results: The results of in vitro transdermal delivery experiment and in vitro release experiment showed that ferulic acid permeated at the constant speed of 0.2142?g?cm -2 ?h -1 in 24 hours and its release coincided with Higuchi Equation.Futhermore,the release rate was 14.53?g?cm -2 ?h -1/2 . Conclusion: CPH is a skeleton controlledtransdermal delivery system whose permeation speed is limited by skin.

Aim To study inhibitory effect of 5-fluorouracil encapsulated by galactosylceramide liposomes (5-Fu-GCL)on 5-Fu-resistent HepG_2 cells and its mechanisms. Methods Inhibitory effect of 5-Fu-GCL on established model of 5-Fu-resistant HepG_2 cells was assessed with MTT assay in vitro. The concentration-time course of 5-Fu-GCL in intracellular fluid was detected with high performance liquid chromatography (HPLC). Thymidylic acid synthase (TS) expression was observed with immunohistochemical method,and NO content was determined with chemical method. Results Obvious inhibitory effects of 5-Fu-GCL (75,150,300,600,1200?mol?L-1) on 5-Fu-resistant HepG_2 cells were observed with IC_ 50 of 158.6 ?mol?L-1,far lower than that of free 5-Fu (400.9 ?mol?L-1). 5-Fu-GCL (300 ?mol?L-1) inhibited 5-Fu-resistant HepG_2 cells in a time-dependent manner,and the inhibitory effect of 5-Fu-GCL was stronger than that of free 5-Fu during 12~48 h. Compared with free 5-Fu,5-Fu-GCL (300 ?mol?L-1) increased the content of intracellular fluid in 5-Fu-resistant HepG_2 cells. 5-Fu-GCL(62.5,300,1200 ?mol?L-1) not only inhibited the expression of TS,but also increased the production of NO in 5-Fu-resistant HepG_2 cells,and these effects of 5-Fu-GCL(300,1200 ?mol?L-1) were stronger than those of free 5-Fu. Conclusion 5-Fu-GCL has inhibitory effect on 5-Fu-resistant HepG_2 cells. The effect may be related to the increased concentration of 5-Fu-GCL in intracellular fluid,inhibited expression of TS and increased production of NO.

OBJECTIVETo investigate the emergency treatment for large amputated ear defect.
METHODSFrom Feb. 2010 to Oct. 2013, 5 cases with large unilateral amputated ear defects were treated. The amputated auricular cartilage was replanted subcutaneously in mastoid area at the first stage. Cranioauricular sulcus was reconstructed and skin grafting was performed at the second stage.
RESULTSAll cases were followed up for 3-6 months with satisfactory result. The reconstructed helix, scapha and cavity of auricular concha had similar color and elasticity as the ear at healthy side. Scar at donor sites, such as inguinal region and armpit, was inconspicuous.
CONCLUSIONSThe method of auricular cartilage replantation is an effective way for emergency treatment of large amputated auricular defect with less morbidity at donor site.

ObjectiveTo examine the relationship between HIF-1αt and VEGF expression and the clinicopathological characteristics in hypopharyngeal squamous cell carcinoma. Methods The expression status of HIF-1α and VEGF were examined by immunohistochemistric method (IHC) in 62 tumor tissue and 19 paracancerous normal tissue.The relationships between the expression of HIF-1α and VEGF and clinicopathological characteristic were analyzed. Results HIF-1αt and VEGF expression were higher in hypopharyngeal carcinoma tissues than those in paracancerous normal tissues (66. 1%:26. 3% ;x2 =18. 02,P <0. 05 ;67. 7% : 31.6% ; x2 =19.22, P < 0. 05 ). The expression intensity of HIF-1 α was related to T stage, N stage and TNM stage ( x2 =4. 23,5.83,9.94,all P <0. 05). The expression intensity of VEGF was related to metastasis, T stage, N stage and TNM stage (x2 =5.62,7. 38,15.75,4. 29 ,all P <0. 05 ). There was minus relationship between overall survival and expression level of HIF-1 α and/or VEGF (x2 =29. 25, P<0.01; x2 =24.88, P< 0.01 ).On multivariate analysis,HIF-1α expression and T stage were independent prognostic factors for overall survival (x2 =4.80,5.74, all P<0. 05).ConclusionsHIF-1α and VEGF may be considered as a parameter in evaluation of progression, metastasis and prognosis of hypopharyngeal carcinoma and also may be a direction of molecular target therapy.

OBJECTIVE:
To study a surgical and repairing method for defects after the resection of basal cell carcinoma of external nose.
METHOD:
There are 26 cases of basal cell carcinoma that tumors have been resected completely after operation. For defect repairing in those 26 cases, 2 cases adopt direct suture method; 2 cases use skin graft repairing methods; 18 cases employ naselabial skin flap repairing method; 4 cases choose forehead pedicle skin flap repairing methods.
RESULT:
the wound of all the 26 cases was primary healed. Additionally, skin flap and skin graft were all survived. Follow-up studied in patients 1 to 3 years after the surgery showed that the local scar was not obvious and no tumor recurred or transferred.
CONCLUSION
Different surgical and repairing methods are performed to obtain a satisfactory results based on the area of defect and its location in nose. Naselabial skin flap is especially an ideal method to repair defects.
