OBJECTIVETo study the over-expression of mutant p53 protein in non-mucinous adenocarcinoma in-situ (NMAIS) and invasive adenocarcinoma, NOS of lung.

METHODSImmunohistochemical study for p53 protein was performed on 17 cases of NMAIS and 70 cases of invasive adenocarcinoma, NOS of lung. The difference in p53 over-expression between the two tumor subtypes was analyzed.

RESULTSThe over-expression of mutant p53 protein was observed in 0 case (0%) of NMAIS and 37 cases (52.9%) of invasive adenocarcinoma, NOS of lung. The difference was of statistical significance (P = 0.000).

CONCLUSIONMutant p53 protein over-expression may play a role in the progression of NMAIS to invasive adenocarcinoma, NOS.

Objective:To discuss the significance of standardized treatment for cancer pain, according to the Cancer Pain Treat-ment Specification (2011 Edition) issued by the Ministry of Health, PR China. Methods:Clinical data of 126 patients with cancer pain, who were admitted to the Department of Medical Oncology, The Fourth Hospital of Hebei Medical University, were collected to com-pare the improvement of the Numeric Rating Scale (NRS) score, number of breakthrough pain, and quality of life score after treatment. The relationships between different pain grades, disease entities, and treatment effect were analyzed. The influence factors of pain relief were also analyzed by using Logistic regression analysis. Results:1). Following standardized treatment, the improvement rate of NRS score has shown significant differences in pain grading (P=0.001) and gender (P=0.000). However, no significant differences were ob-served between different diseases (P=0.112). The improvement rate of the life quality score and the number of breakthrough pain had no significant difference after standardized treatment. 2). The grading of cancer pain and the disease entities had little effect on cancer pain relief. 3). The anti-tumor treatment and“no distant metastasis”were the independent factors that brought about the decrease in NRS and quality of life scores.“No distant metastasis”(P=0.046) was the independent factor that reduced the number of pain out-breaks. Conclusion: The standardized treatment positively affects the NRS score, number of breakthrough pain, and quality of life score. Patients who received anti-neoplastic therapy and who had no distant metastasis showed significant treatment effectiveness in pain management.

A novel biosensor for aflatoxin B1 detecting has been reported. The biosensor electrode for AFB1 detecting was assembled by immobilized aflatoxin-oxidoreductase using open-ended multi-walled carbon nanotubes as matrix. Its linear range was between 0.16?M and 3.2?M. And if the specific anti-aflatoxin B1 antibody and aflatoxin oxidoreductase were both immobilized on the electrode with Multi-Walled carbon nanotubes, the detection limit of the modified electrode could be 16 nM with a 10 times improved sensitivity. The aflatoxin enzyme biosensor assembled this way strode one step forward its practical application.

Mongolian folk medicine resource is the origin of Mongolian medicine development, even more important of which is the specialized Mongolian folk medicine resources with regional and high medicine quality, it processes distinctive national characteristics with irreplaceable important position in traditional Mongolian medicine. Nevertheless, due to the serious destroy of ecological environment and sharp increase of demands, etc. A lot of specialized Mongolian folk medicine resources were endangered, and there still existed some problems in the protection and exploitation and utilization. This paper intends to provide comprehensive insight into the species protection and exploitation and utilization states of specialized Mongolian folk medicine resources. The application and protection status and the existing problems were reviewed, and the development strategies of Mongolian folk medicine resource were analyzed.

Objective To explore the ideal treatment mode of brain metastases by Meta-analysis.Methods Articles were searched for from the databases at home and abroad using English and Chinese keywords.Searching time limited from the databases setting up to December 30,2012.Jadad score was applied to evaluate the qualities of literatures.RevMan5.0 software was applied to perform the Meta-analysis.A totle of 25 articles including 2 750 patients were eligible for the Meta-analysis,which divided into groups with different treatment.Results Compared with monotherapy,combined therapy improved 1-year survival (OR =0.58,95％ CI:0.46 ～0.71,P ＜0.000 01).In combined therapy groups,compared with two methods,three kinds of therapies improved 1-year survival (OR =0.63,95 ％ CI:0.50 ～ 0.80,P =0.000 1).Compared with local therapy only or systemic therapy only,systemic combined local therapy improved 1-year survival (OR =0.68,95％ CI:0.53 ～ 0.86,P =0.001 ; OR =0.59,95％ CI:0.41 ～ 0.86,P =0.006).In systemic combined local therapy groups,three kinds of treatments improved 1-year survival compared with two methods (OR =0.52,95％ CI:0.35 ～ 0.78,P =0.002).Compared with non-molecular targeted therapy,molecular targeted therapy improved 1-year survival (OR =0.76,95％ CI:0.67 ～ 0.87,P ＜ 0.000 1).Conclusion The reasonable treatment for patients with brain metastases is combined treatment with operation,radiotherapy and chemotherapy.There is better curative effect added molecular targeted therapy based on original scheme,if patients have targeted therapy indications.

Objective To investigate and compare the action of curcuminoids on the causal pathogens of Candida albicans growth.Methods The effects of curcumin (CUR) and demethoxycurcumin (DMC) on C.albicans growth were first investigated and compared by microcalorimetry coupled with multiple analytical methods.The quantitative thermo-kinetic parameters obtained from these curves were analyzed to show difference of the actions.Results By analyzing the main parameters screened from principal component analysis together with 50％ inhibiting concentration values,it was demonstrated that both CUR and DMC showed good antifungal activities and CUR was stronger.It was further concluded from structure-activity relationship that the existence of methoxy group might enhance lipophilicity of the mother nucleus,which made it easier for the molecular to enter into the cell membrane of fungi to inhibit its growth.Conclusion This study provides a new method for screening new antifungal agents with high efficacy and low toxicity.Meanwhile,it contributes to the application of curcuminoids as food additive,colorant,and drug.Microcalorimetry is real-time,online,and dynamic,and it could be used to characterize the subtle difference among the effects of synthetic and natural products on the vital process of fungi.

Objective To investigate the protective effects of Ulinastatin (UTI) and 1, 6 fructose diphosphate (FDP) on cerebral ischemia-reperfusion injury, and to discuss the protective mechanisms of UT1 and FDP on cerebral ischemia-repeffusion injury. Method Rabbit ischemia-repeffusion injury models were prepared by"four arteries occlusion". All rabbits were divided into four groups (n=6): control group, UTI (10 U/kg) group, FDP (200 mg/kg) group, UTI+ FDP group. Salt water, UTI, FDP and UTI + FDP were respectively used immediately after ischemia-reperfusion. Plasmic MDA and GSH-Px were measured at 30 minutes, 1 hour, 3 hours and 6 hours after reperfusion. Results The concentrations of plasmic MDA in every group were significantly improved compared with those in control group (P0.05 ), but significant difference could be found after 3 hours (P

Objective To discuss the surgical outcome and operative technique of the modified trans-petrosal presigmoid approach in treating cases with facial nerve palsy after petral bone fracture trea- ted with facial nerve canal decompression method.Methods A total of 15 cases with facial nerve pal- sy were treated with traumatic facial nerve canal decompression technique with the trans-petrosal presig- mold approach combined with high-dose hormone therapy,whereas 12 cases were treated with traditional Chinese medicine.The clinical data were analysed and compared retrospectively according to House- Brackmann facial nerve grading scale.Results At acute stage,eight(53.3%)out of 15 cases recov- ered to levelⅠ(P＜0.05),with no significant postoperative complications such as CSF leakage. Conclusions This approach is simple and safe and can expose extensively the facial nerve bone canal and effectively alleviate the edemous facial nerve aided by high-dose hormone therapy.Therefore,it is suitable for surgical treatment of acute facial nerve palsy after petral bone fractures.
